05958122 | 1 | E2fsprogs 1.42.8 (June 20, 2013) |
6e2393fd TT |
2 | ================================ |
3 | ||
4 | As a part of mke2fs's option parsing cleanup, the use of the -R option | |
5 | will give a warning that it is depreated (it has been so documented | |
6 | since 2005) and -E should be used instead. | |
7 | ||
8 | Mke2fs will not give warnings about the bigalloc and quota options in | |
9 | quiet mode. | |
10 | ||
05958122 TT |
11 | If an invalid journal size is given to mke2fs, it will now complain |
12 | and exit sooner. | |
13 | ||
6e2393fd TT |
14 | Debugfs was erroneously giving spurious error messages for certain |
15 | extent_inode subcommands which take arguments (split_node, | |
16 | replace_node, and insert_node). This has been fixed. | |
17 | ||
18 | Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among | |
19 | other programs is used by mke2fs. | |
20 | ||
21 | Change mke2fs so that it does not set the root directory to the real | |
22 | uid/gid of the mke2fs process. Add the extended option root_owner to | |
23 | override this behavior. | |
24 | ||
05958122 TT |
25 | Fix resize2fs when shrinking file systems to make sure that bitmap |
26 | blocks aren't left outside the bounds of the shrunken file system. | |
27 | This could happen with flex_bg file systems that were grown using | |
28 | the old online resizing algorithm. | |
29 | ||
6e2393fd TT |
30 | E2fsck will now detect and repair corrupted extent trees which contain |
31 | invalid extents at the end of the extent tree leaf block. | |
32 | ||
33 | E2fsck will now longer complain about zero length extended attribute | |
34 | values. | |
35 | ||
36 | Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s | |
37 | to crash. | |
38 | ||
39 | Add safety check so tune2fs will not attempt to set the inode size to | |
40 | be larger than the block size. | |
41 | ||
42 | Fix e2fsck so it can check a read-only root file system with an | |
43 | external journal. (Addresses Debian Bug: #707030 | |
44 | ||
45 | Fix off-line resizing of file systems with flex_bg && !resize_inode | |
46 | (Addresses Debian Bug: #696746) | |
47 | ||
48 | Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug: | |
49 | #703067) | |
50 | ||
51 | Enhance chattr to allow clearing the extent flag if the kernel allows | |
52 | migrating extent based files to use indirect blocks. | |
53 | ||
54 | Update German translation. | |
55 | ||
56 | Updated/fixed various man pages. (Addresses Debian Bugs: #712429, | |
57 | #712430, #707609) | |
58 | ||
59 | Fixed various Debian Packaging Issues (Addresses Debian Bug #708307) | |
60 | ||
61 | Programmer's Notes | |
62 | ------------------ | |
63 | ||
64 | Use secure_getenv() in preference to __secure_getenv(). | |
65 | ||
66 | Optimize CPU utilization of ext2fs_bg_has_super(). | |
67 | ||
68 | Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when | |
69 | SEEK_CUR is used with large files. | |
70 | ||
71 | The ext2fs_read_inode_full() function will no longer use | |
72 | fs->read_inode() if the caller has requested more than the base 128 | |
73 | byte inode structure and the inode size is greater than 128 bytes. | |
74 | ||
75 | Fix build failure with --enable-jbd-debug. | |
76 | ||
77 | Clean up filtering of outputs for the regression tests by using a | |
78 | common sed script. | |
79 | ||
80 | Fix gcc -Wall and clang nits. | |

8359f626 | 84 | =================================== |
73c427d2 | 85 | |
511ba985 TT |
86 | Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and |
87 | quota features are still under development. For more information | |
88 | please see: | |
89 | * https://ext4.wiki.kernel.org/index.php/Bigalloc | |
90 | * https://ext4.wiki.kernel.org/index.php/Quota | |
91 | ||
73c427d2 TT |
92 | Add some new options to filefrag from Lustre's patches to e2fsprogs: |
93 | * add -k option to print extents in kB-sized units (like df -k) | |
94 | * add -b {blocksize} to print extents in blocksize units | |
95 | * add -e option to print extent format, even when FIBMAP is used | |
96 | * add -X option to print extents in hexadecimal format | |
97 | ||
98 | Fix resize2fs so that it can handle off-line resizes of file systems | |
99 | with the flex_bg feature but without a resize_inode (or if we run out | |
100 | of reserved gdt blocks). This also fixes a problem where if the user | |
101 | creates a filesystem with a restricted number of reserved gdt blocks, | |
102 | an off-line resize which grows the file system could potentially | |
103 | result in file system corruption. | |
104 | ||
511ba985 TT |
105 | Fix a resize2fs bug which could cause it to corrupt bigalloc file |
106 | systems when doing an off-line resize. | |
107 | ||
8359f626 TT |
108 | Further optimize resize2fs so it doesn't use quite as much CPU when |
109 | resizing very large file systems. | |
110 | ||
111 | Fixed 32-bit overflow bugs which could cause resize2fs to fail and | |
112 | possibly corrupt the file system while resizing 64-bit file systems. | |
113 | ||
73c427d2 TT |
114 | Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a |
115 | mke2fs crash due to a divide-by-zero if the 64bit file system feature | |
116 | is enabled. | |
117 | ||
8359f626 TT |
118 | Add better error checking to mke2fs to check for invalid parameters |
119 | when creating bigalloc file system. | |
120 | ||
121 | When creating bigalloc filesystems, the -g option to mke2fs will now | |
122 | specify the number of clusters per block group. | |
123 | ||
73c427d2 TT |
124 | Add to debugfs the functionality to corrupt a specific file system |
125 | block via the "zap_block" command. | |
126 | ||
127 | Add to debugfs the functionality to print out a hex dump of a block in | |
128 | the file system via the "block_dump" command. | |
129 | ||
130 | Add to debugfs the functionality to manipulate the extent tree | |
131 | directly via the "extent_open" command. | |
132 | ||
8359f626 TT |
133 | Fixed debugfs's mknod command so that it updates the block group |
134 | statistics. | |
135 | ||
73c427d2 TT |
136 | Fix e2fsck so it can detect and fix inconsistencies in the interior |
137 | nodes of an inode's extent tree. | |
138 | ||
8359f626 TT |
139 | Fix a potential memory corruption failure in e2fsck's error path if |
140 | the call to ext2fs_open2() fails. | |
141 | ||
142 | Fix e2fsck if its logging function is enabled in e2fsck.conf, and the | |
143 | resulting file name for the log file is longer than 100 bytes, that it | |
144 | properly handles this situation instead of crashing. | |
145 | ||
146 | E2fsck will now report the amount of memory that it attempted to | |
147 | allocate when a memory allocation request fails, to make it easier to | |
148 | track down the problem. | |
149 | ||
73c427d2 TT |
150 | Fix mke2fs's handling of the mmp_update_interval option. (Addresses |
151 | Lustre Bug: LU-1888) | |
152 | ||
8359f626 TT |
153 | E2image can now include all data blocks in the e2image output file |
154 | when the user specifies the -a option. | |
155 | ||
73c427d2 TT |
156 | If e2fsprogs is compiled without --enable-quota, make sure that |
157 | tune2fs can not turn on the feature for new-style quota support, since | |
158 | afterwards, none of the e2fsprogs tools will be willing to touch that | |
159 | file system. | |
160 | ||
161 | Optimize e2fsck's so that it uses much less CPU for large file | |
162 | systems. This can result in significant speedups, especially on | |
163 | CPU-constrained systems. This was primarily done by optimizing | |
164 | libext2fs's bitmap functions. (Addresses Google Bug: #7534813) | |
165 | ||
166 | Fix debugfs's htree command so that all its messages are sent through | |
167 | the pager. | |
168 | ||
169 | Fixed debugfs's "dump_file" and "cat" functions work correctly | |
170 | on file systems whose block size is greater than 8k. | |
171 | ||
172 | Fix e2freefrag so it works on 64-bit file systems, and so it uses much | |
173 | less memory. (Addresses Google Bug: 7269948) | |
174 | ||
511ba985 TT |
175 | Update the spd_readdir.c file in the contrib directory to include some |
176 | additions which were made in 2008 that didn't get folded into the | |
177 | version which we checked into the e2fsprogs source tree. These | |
178 | enhancements include thread safety, support for readdir64_r(), and | |
179 | safe_getenv() support in case spd_readdir.so is used for setuid binaries. | |
180 | ||
8359f626 TT |
181 | Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese |
182 | translations | |
183 | ||
184 | Add a command to debugfs to create symlinks. | |
185 | ||
186 | Document the bigalloc feature in the mke2fs man page. (Addresses | |
187 | Debian Bug: #669730) | |

189 | |
190 | Programmer's Notes | |
191 | ------------------ | |
192 | ||
193 | Fix gcc -Wall nits. | |
194 | ||
195 | Fix a spelling typo in the libext2fs texinfo documentation. | |
196 | ||
197 | Change the output from "make check" so that tools such as emacs's "M-x | |
198 | compile" does not mistake the output as containing a compiler error. | |
199 | ||
200 | Export two new functions from libext2fs: ext2fs_extent_node_split() | |
201 | and ext2fs_extent_goto2(). | |
202 | ||
203 | The ext2fs_extents_fix_parents() was fixed so it does not modify the | |
204 | location of the extent handle if its current location is at an | |
205 | interior node, rather than a leaf node of an inode's extent tree. | |
206 | ||
511ba985 | 207 | Add a regression test to assure that e2fsck can correctly fix an |
73c427d2 TT |
208 | inconsistent interior node in an inode's extent tree. |
209 | ||
511ba985 TT |
210 | The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now |
211 | correctly support bigalloc file systems which use store block usage | |
212 | information in units of clusters. | |
213 | ||
73c427d2 TT |
214 | Fixed the help text in the configure script for --enable-quota. |
215 | ||
216 | The m68k-specific bitops code has been removed since they were | |
217 | incorrectly treating bit numbers with the high bit set as signed | |
218 | integers. Furthermore, modern compilers do a good enough job | |
219 | optimizing the generic code there is no point in having the m68k | |
220 | specific asm statements. | |
221 | ||
222 | Fixed how we link the test programs so they always use the static | |
223 | libraries, so that we test using the libraries which we have just | |
224 | built. | |
225 | ||
8359f626 TT |
226 | Update config.guess and config.sub to the latest versions from the GNU |
227 | project. | |
228 | ||
229 | Fixed the com_err.texinfo file so that it can produce a valid | |
230 | postscript/pdf printed output. | |
231 | ||
232 | Add a regression test which checks debugfs's ability to create | |
233 | symlinks, named FIFO's, and device nodes. | |
234 | ||
235 | Add a function ext2fs_symlink(), which creates symlinks to the | |
236 | libext2fs library. | |
237 | ||
238 | Add debugging code so we can test old kernel interfaces for online | |
239 | resize to resize2fs. This backwards compatibility checking is keyed | |
240 | off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to | |
241 | test the functionality of the kernel's older resize ioctls without | |
242 | needing to install an old version of resize2fs, and to also test a | |
243 | modern resize2fs's ability to work with older kernels without having | |
244 | to install an older version of the kernel. | |
245 | ||

247 | E2fsprogs 1.42.6 (September 21, 2012) |
248 | ===================================== | |
249 | ||
250 | When mke2fs creates file systems with lazy itable initialization, the | |
251 | progress updates for writing the inode table happens so quickly that | |
252 | on a serial console, the time to write the progress updates can be the | |
253 | bottleneck. So mke2fs will now only update its progress indicators | |
254 | once a second. | |
255 | ||
256 | Resize2fs will skip initializing the inode tables if the kernel | |
257 | supports lazy_itable_init, which speeds up growing off-line growth of | |
258 | uninit_bg file systems significantly. Resize2fs will now also | |
259 | correctly set the itable_unused field in the block group descriptor to | |
260 | speed up the first e2fsck after the file system is grown. | |
261 | ||
262 | Resize2fs has been fixed so that on-line resizing of meta_bg file | |
263 | systems work correctly. This is needed to grow file system which are | |
264 | larger than 16T. | |
265 | ||
266 | Resize2fs will now correctly handle resizing file systems to 16TB on | |
267 | 32-bit file systems when "16TB" is specified on the command line. | |
268 | ||
269 | Fix mke2fs so that it will be careful to set the reserved blocks ratio | |
270 | larger than 50%; this can happen when creating small file systems and | |
271 | when the last block group is dropped because there are not enough | |
272 | blocks to support the metadata blocks in the last block group. | |
273 | ||
274 | Fixed spelling mistake in debugfs's help message. | |
275 | ||
276 | Fixed a potential seg fault in e2fsck when there is an I/O error while | |
277 | reading the superblock. | |
278 | ||
279 | Fixed various Debian Packaging Issues (Addresses Debian Bug #677497) | |
280 | ||
281 | Updated/fixed various man pages. (Addresses Sourceforge Bug: | |
282 | #3559210) | |
283 | ||
284 | Programmer's Notes | |
285 | ------------------ | |
286 | ||
287 | The configure option --enable-relative-symlink was broken so that it | |
288 | needed to be --enable-symlink-relative-symlinks. We will support both | |
289 | for at least two years, but then the worng configure option will be | |
290 | removed. | |
291 | ||
292 | Fixed a regression introduced in 1.42.5 so the link order for | |
293 | e2fsprogs' libraries will be correct for both static and shared | |
294 | linking. (Addresses Sourceforge Bug: #3554345) | |
295 | ||
296 | Add support for e2fsprogs to be compiled using clang/LLVM. | |
297 | ||
298 | Fix portability problems on non-Linux systems: avoid compile failures | |
299 | on systems that don't have malloc.h | |
300 | ||
301 | Fix f_mmp regression test suite so that debugfs gets killed if the | |
302 | test is interrupted. | |
303 | ||

67b3721d TT |
306 | E2fsprogs 1.42.5 (July 29, 2012) |
307 | ================================ | |
308 | ||
309 | Fixed a bug with mke2fs where if there is only 8 inodes per block | |
310 | group, the calculation of the number of uninitialized inodes in the | |
311 | first block group would go negative. This resulted in "mke2fs -N 256 | |
312 | -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp | |
313 | would run out of space. (Addresses Sourceforge Bug: #3528892) | |
314 | ||
315 | Fixed a bug in how e2fsck would uniquify directory entry names. | |
316 | (AddressesSourceforge Bug: #3540545) | |
317 | ||
318 | Previously, e2fsck would only allow a mounted file system to be | |
319 | checked if it was the root file system and it was mounted read-only. | |
320 | Now it will allow any file system mounted read-only to be checked if | |
321 | the -f option is specified. This makes it easier to test how e2fsck | |
322 | handles checking file systems which are mounted without having to test | |
323 | on the root file system. | |
324 | ||
325 | Fixed a problem if e2fsck where if the root file system is mounted | |
326 | read-only, e2fsck would not clear an error indication in the journal | |
327 | superblock. Combined with a kernel bug, this would cause the e2fsck | |
328 | to check the file system after every single boot. | |
329 | ||
330 | The e4defrag program can now handle device symlinks, such as | |
331 | /dev/mapper/testvg-testlv, instead of insisting on a less | |
332 | human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla: | |
333 | #707209) | |
334 | ||
335 | Fixed filefrag so it will not crash with a segfault on files from a | |
336 | virtual file system such as /proc. (e.g., "filefrag | |
337 | /proc/partitions") | |
338 | ||
339 | Fixed filefrag so that it correctly reports the number of extents. | |
340 | (Addresses Red Hat Bugzilla: #840848) | |
341 | ||
342 | Fixed a file descriptor leak in logsave which could cause it to hang. | |
343 | (Addresses Debian Bug: #682592) | |
344 | ||
345 | Fixed e2fsck so that the file system is marked as containing an error | |
346 | if the user chooses not to fix the quota usage information. | |
347 | ||
348 | Fixed tune2fs so that it correctly removes the quota feature when the | |
349 | last quota inode is removed. | |
350 | ||
351 | Fix tune2fs so that after removing a quota inode, the block bitmap is | |
352 | updated; otherwise, e2fsck would complain after running 'tune2fs -O | |
353 | ^quota <dev>'. | |
354 | ||
355 | Fix tune2fs so that when converting a file system from using legacy | |
356 | quota files to the new quota file system feature with hidden quota | |
357 | files, the accounting for these files is handled correctly so that | |
358 | e2fsck doesn't complain. | |
359 | ||
360 | Improved e2fsck's verbose reporting statistics, and allow the more | |
361 | verbose reporting to be enabled via /etc/e2fsck.conf. | |
362 | ||
363 | Fixed various Debian Packaging Issues (Addresses Debian Bug #678395) | |
364 | ||
365 | Updated/fixed various man pages. (Addresses Debian Bugs: #680114) | |
366 | ||
367 | ||
368 | Programmer's Notes | |
369 | ------------------ | |
370 | ||
371 | Fixed portability problems on other operating systems (e.g., Hurd and | |
372 | FreeBsd) caused by the attempted inclusion of <sys/quota.h>. | |
373 | ||
374 | Make sure that shared libraries link with the shared libraries built | |
375 | in the build tree, instead of the system provided libraries. | |
376 | Previously, libraries and executables were linked with the system | |
377 | libraries if present, and possibly using static archives instead of | |
378 | shared libraries. This was also problematic since if libext2fs.so is | |
379 | linked with a static libcom_err.a from system, the build system would | |
380 | attempt to link without -lpthread. (Addresses Sourceforge Bug: | |
381 | #3542572) | |

d6a3e411 TT |
384 | E2fsprogs 1.42.4 (June 12, 2012) |
385 | ================================ | |
386 | ||
387 | Fixed more 64-bit block number bugs (which could end up corrupting | |
388 | file systems!) in e2fsck, debugfs, and libext2fs. | |
389 | ||
390 | Fixed e2fsck's handling of the journal's s_errno field. E2fsck was | |
391 | not properly propagating the journal's s_errno field to the superblock | |
392 | field; it was not checking this field if the journal had already been | |
393 | replayed, and if the journal *was* being replayed, the "error bit" | |
394 | wasn't getting flushed out to disk. | |
395 | ||
396 | Fixed a false positive complaint by e2fsck if all of the extents in | |
397 | the last extent tree block are uninitalized and located after the end | |
398 | of the file as defined by i_size. | |
399 | ||
400 | The dumpe2fs will now display the journal's s_errno field if it is | |
401 | non-zero, and it will also display the journal's 64-bit feature flag | |
402 | if present. | |
403 | ||
404 | Fix e2fsck so that it always opens the device file in exclusive mode | |
405 | when it might need to modify the file system, and never if the -n | |
406 | option is specified. (Previously, there were a few corner cases where | |
407 | it might get things wrong in either direction.) | |
408 | ||
409 | E2fsck now correctly truncates or deallocates extent-mapped inodes on | |
410 | the orphan list. The root cause was a bug in libext2fs's block | |
411 | iterator which could end up skipping an extent when the last block in | |
412 | an extent is removed, causing the current extent to be removed from | |
413 | the extent tree. | |
414 | ||
415 | E2fsck now correctly sets the global free block and inode counts when | |
416 | truncating or removing inodes on the orphan list in preen mode. | |
417 | Previously, it would leave these values would be set incorrectly, | |
418 | which is largely a cosmetic issue since the kernel no longer pays | |
419 | attention to those fields, but it can cause spurious complaints in | |
420 | subsequent e2fsck runs. | |
421 | ||
422 | Fix i_blocks accounting when the libext2fs library needs to add or | |
423 | remove an extent tree block on bigalloc file systems. | |
424 | ||
425 | The lsattr and chattr programs now support the No_COW flag for the | |
426 | benefit of btrfs. | |
427 | ||
428 | Debugfs now interprets date strings of the form @ddd as ddd seconds | |
429 | after the beginning of the epoch. This is handy when setting an inode | |
430 | number into the d_time field when debugging orphan list handling. | |
431 | ||
432 | Fix a precedence bug with built-in quota support which might result in | |
433 | e2fsck paying attention to the quota inode field even if the built-in | |
434 | quota feature flag is not set. Fortunately, in practice that | |
435 | superblock field should be zero for non-built-in quota file systems, | |
436 | so it's unlikely this bug would have caused problems. | |
437 | ||
438 | Updated/fixed various man pages. (Addresses Debian Bugs: #674453, | |
439 | #674694) | |

441 | Programmer's Notes | |
442 | ------------------ | |
443 | ||
444 | The regression test suite can now run the integration tests in the | |
445 | tests directory in parallel, via "make -jN check". | |
446 | ||
447 | Add new test, f_zero_extent_length which tests e2fsck's handling of | |
448 | the case where all of the extents in the last extent tree block are | |
449 | uninitialized extents after i_size. | |
450 | ||
451 | Add a new test, f_jnl_errno, which checks handling of an error | |
452 | indication set in the journal superblock. | |
453 | ||
454 | Fix the test f_jnl_64bit so that it properly checks e2fsck's handling | |
455 | of a 64-bit journal. | |
456 | ||
457 | Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which | |
458 | tests e2fsck's handling of orphan inodes in preen mode, and truncation | |
459 | of extent inodes on the orphan list. | |

464 | E2fsprogs 1.42.3 (May 14, 2012) |
465 | =============================== | |
466 | ||
467 | Fix a bug in the Unix I/O manager which could cause corruption of file | |
468 | systems with more than 16TB when e2fsprogs is compiled in 32-bit mode | |
469 | (i.e., when unsigned long is 32-bits). Also fix a bug which caused | |
470 | dumpe2fs to incorrectly display block numbers > 32-bits. | |
471 | ||
472 | Improve the support for integrated quota files (where quota is a first | |
473 | class supported feature using hidden files in the ext4 file system). | |
474 | Previously the quota file was getting rewritten even when it was not | |
475 | necessary, and e2fsck would erroneously try to hide quota files which | |
476 | were already hidden. | |
477 | ||
478 | Quiet complaints in e2fsck when the total free blocks or inodes are | |
479 | incorrect in the superblock after an system crash, since we don't | |
480 | update nor depend on the superblock summaries at each commit boundary. | |
481 | ||
482 | Fixed a regression introduced in 1.42.2 which would cause applications | |
483 | outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so | |
484 | would were still using the legacy 32-bit bitmaps) to crash. This was | |
485 | due to missing 32-bit compat code in side the function | |
486 | ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla: | |
487 | #808421) | |
488 | ||
489 | Fix a bug which would cause mke2fs to fail creating the journal if | |
490 | /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug: | |
491 | #3509398) | |
492 | ||
493 | Updated/fixed various man pages. | |
494 | ||
495 | Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese | |
496 | translations | |
497 | ||
498 | Fixed various Debian Packaging issues. | |
499 | ||
500 | ||
501 | Programmer's Notes | |
502 | ------------------ | |
503 | ||
504 | Change the nonsensically wrong types in the function signature of the | |
505 | inline function ext2fs_find_first_zero_block_bitmap2(). This was | |
506 | caused by a cut and paste error; fortunately no code in e2fsprogs used | |
507 | this inline function, and there are any users of this functions | |
508 | outside of e2fsprogs. | |
509 | ||
510 | Add support for systems which have valloc(), but which do have | |
511 | posix_memalign() nor memalign() (such as MacOS 10.5). | |
512 | ||
513 | Refactor and clean up the allocation of aligned buffers for Direct I/O | |
514 | support. Previously some allocations were requesting a greater | |
515 | alignment factor that what was strictly necessary. Also optimize | |
516 | reading and writing bitmaps using Direct I/O when the size of the | |
517 | bitmap did not fully cover the file system blocksize. | |
518 | ||
519 | Reserve the codepoints for the INCOMPAT features LARGEDATA and | |
520 | INLINEDATA. | |
521 | ||
522 | Improved the regression test suite by adding some new integration | |
523 | tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk | |
524 | jbd2 format, as well as f_eofblocks which tests the new handling of | |
525 | uninitialized and initialized blocks beyond i_size. Also add a new | |
526 | unit test which verifies 32-bit bitmaps support and the new | |
527 | find_first_zero primitives. | |
528 | ||
529 | Add a few dependencies to fix parallel (make -j) builds. | |
530 | ||
531 | Removed bash'isms which were breaking the regression test suite on | |
532 | systems where /bin/sh is not bash. | |
533 | ||
534 | The config.guess and config.sub have been updated to the 2012-02-10 | |
535 | version. | |
536 | ||
537 | Fix a portability problem caused by assuming the present of mntent.h | |
538 | means that setmntent() exists. Instead, explicitly test for this in | |
539 | the configure script. | |
540 | ||
541 | If the sys/signal.h header file does not exist, don't try to include | |
542 | it, since it's not available on all systems. | |
543 | ||
544 | Add support for systems that do not support getpwuid_r() | |
545 | ||
546 | The configure script now supports a new option, | |
547 | --enable-relative-symlinks, which will install relative symlinks for | |
548 | the ELF shared library files. (Addresses Sourceforge Bug: #3520767). | |
549 | ||
550 | When building BSD shared libraries make sure the LDFLAGS variable is | |
551 | passed to the linker. Fixing this allows, for example, e2fsprogs to | |
552 | be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug: | |
553 | #3517272) | |
554 | ||
555 | Fix gcc -Wall nitpicks | |
556 | ||
557 | ||
70d7281d TT |
558 | E2fsprogs 1.42.2 (March 27, 2012) |
559 | ================================= | |
560 | ||
561 | The resize2fs program uses much less CPU and is much faster for very | |
562 | large file systems. (Addresses Debian Bug: #663237) | |
563 | ||
564 | The seti and freei commands in debugfs can now take an optional length | |
565 | argument to set and clear a contiguous range of inodes. | |
566 | ||
567 | E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we | |
568 | plan to remove support for it from the kernel file system driver. It | |
569 | really wasn't very useful and was causing more problems than it | |
570 | solves. Since e2fsck will complain if inodes that should have | |
571 | EOFBLOCKS_FL do not have the flag set, we are going to remove this | |
572 | check from e2fsprogs first, and then only remove the flag from the | |
573 | kernel much later. | |
574 | ||
575 | The mke2fs program can now use direct I/O via "mke2fs -D". This will | |
576 | slow down the mke2fs, but it makes it more polite on a loaded server | |
577 | by limiting the amount of memory that gets dirtied by mke2fs when it | |
578 | is using buffered I/O. | |
579 | ||
580 | E2fsck was needlessly closing and re-opening the file system as a side | |
581 | effect of adding Multiple Mount Protection (MMP). This isn't | |
582 | necessary for non-MMP file systems, so drop it. | |
583 | ||
584 | Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we | |
585 | can more easily diagnose memory allocation failures caused by | |
586 | insufficient memory. E2fsck will now abort if there are memory | |
587 | allocation failures when the file system is initially opened and | |
588 | during the block group descriptor checks. (Addresses Google Bug: | |
589 | #6208183) | |
590 | ||
591 | If there are incorrect block group checks, e2fsck will now report the | |
592 | incorrect and corrected checksum values. | |
593 | ||
594 | The e2fsck progam can now write log files containing the details of | |
595 | the problems that were found and fixed directly, via configuration | |
596 | parameters in /etc/e2fsck.conf. | |
597 | ||
598 | Added the ability to limit the number of messages reported by e2fsck | |
599 | for a given problem type. This avoids a potential bottleneck if there | |
600 | is a serial console which can cause a boot sequence to take a long | |
601 | time if e2fsck needs to report many, many file system errors. | |
602 | ||
603 | The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause | |
604 | them to use much less memory for large file systems. | |
605 | ||
606 | The dumpe2fs program will now print the expected block group checksum | |
607 | if it is incorrect. This helps to diagnose problems caused by | |
608 | incorrect block group checksums. | |
609 | ||
610 | E2fsck now checks for extents with a zero length, since the kernel | |
611 | will oops if it comes accross such a corrupted data structure. (See | |
612 | https://bugzilla.kernel.org/show_bug.cgi?id=42859) | |
613 | ||
614 | E2fsck has a number of bugs relating to discard that have been fixed. | |
615 | (1) Fixed a bug which could cause e2fsck to discard portions of the | |
616 | inode table which were actually in use. (2) E2fsck will now avoid | |
617 | using discard if the block device doesn't zero data on discard, since | |
618 | otherwise this could cause problems if the file system gets corrupted | |
619 | in the future. (3) E2fsck will now avoid using discard when it is run | |
620 | in read-only mode. (4) Fixed a bug which caused e2fsck to not issue | |
621 | discards in the last block group. | |
622 | ||
623 | E2fsck's CPU utilization in pass 5 has been optimized, which will | |
624 | speed up e2fsck slightly. | |
625 | ||
626 | E2image will now skip copying uninitialized bitmap and inode table | |
627 | blocks. | |
628 | ||
629 | Fixed mke2fs -S so it does not corrupt the first block group's | |
630 | information. | |
631 | ||
632 | E2fsck will now check the new sysfs interface to determine if we are | |
633 | using the battery or AC mains. (Addresses SourceForge Bug: #3439277) | |
634 | ||
635 | Updated/fixed various man pages. (Addresses Debian Bug: #665427) | |
636 | ||
637 | Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885) | |
638 | ||
639 | Programmer's Notes | |
640 | ------------------ | |
641 | ||
642 | Fixed various portability issues for non-Linux systems, particularly | |
643 | MacOS X, as well as Linux systems running with the just-released glibc | |
644 | 2.15. | |
645 | ||
646 | Fix file descriptor leak in ext2fs_close() if the file system with | |
647 | uninit_bg is opened read/only with a backup superblock. (Addresses | |
648 | SourceForge Bug: #3444351) | |
649 | ||
650 | Fixed an invalid return in a non-void function in the quota code. | |
651 | (Addresses SourceForge Bug: #3468423) | |
652 | ||
653 | Fixed the debian rules file so that the calls to dpkg-buildflags works | |
654 | when the shell is dash. | |
655 | ||
656 | The debian package build now uses V=1 so that there is more | |
657 | information about potential build failures in debian buildd logs. | |
658 | ||
659 | If the uninit flags get cleared by functions such as | |
660 | ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the | |
661 | superblock is marked dirty and the block group descriptor checksum is | |
662 | updated if necessary. | |
663 | ||
664 | The debian rules file will now try to load debian/rules.custom of it | |
665 | exists. This flie can skip various builds for speed reasons if there | |
666 | is no need for the e2fsck-static or udeb packages. Available | |
667 | customizations in the rules file includes SKIP_STATIC=yes, | |
668 | SKIP_BF=yes, and SKIP_DIETLIBC=yes. | |
669 | ||
670 | In addition, if the file misc/mke2fs.conf.custom.in exists in the | |
671 | source tree, it will be used instead of the standard misc.conf file in | |
672 | the upstream sources. This makes it easier for Debian-derived systems | |
673 | to distribute a custom mke2fs.conf file without having to worry about | |
674 | merge issues if future versions of e2fsprogs makes changes in the | |
675 | upstream default version of mke2fs.conf. | |
676 | ||
677 | ||
91b9eade TT |
678 | E2fsprogs 1.42.1 (February 17, 2012) |
679 | =================================== | |
680 | ||
681 | The mke2fs and e2fsck now use significantly less memory when creating | |
682 | or checking very large file systems. This was enabled by adding | |
683 | extent-based bitmaps which are stored using a red-block tree, since | |
684 | block and inode allocations tend to be contiguous. | |
685 | ||
686 | The command mke2fs -S is used as a last ditch recovery command to | |
687 | write new superblock and block group descriptors, but _not_ to destroy | |
688 | the inode table in hopes of recovering from a badly corrupted file | |
689 | system. So if the uninit_bg feature is enabled, mke2fs -S will now | |
690 | set the unused inodes count field to zero. Otherwise, e2fsck -fy | |
691 | after using mke2fs -S would leave the file system completely empty. | |
692 | ||
693 | Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also | |
694 | honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has | |
695 | installed an mke2fs binary using that name. | |
696 | ||
697 | The usage and help messages for the -G, -t and -T options in mke2fs | |
698 | have been fixed. | |
699 | ||
700 | If e2fsck needs to use the backup group descriptors, the | |
701 | ext2fs_open2() function clears the UNINIT bits to ensure all of the | |
702 | inodes in the file systems get scanned. However, the code which reset | |
703 | the UNINIT flags did not also recalculate the checksum, which produced | |
704 | many spurious (and scary) e2fsck messages. This has been fixed by | |
705 | resetting cheksums when the UNINIT bits are cleared. | |
706 | ||
707 | Relax a check in e2fsck which required that the block bitmap to be | |
708 | initialized when the inode bitmap is in use. This will allow us to | |
709 | eventually eliminate code from the kernel which forcibly initialized | |
710 | the block bitmap when the inode bitmap is first used, requiring an | |
711 | extra journal credit and disk write. (Addresses Google Bug: #5944440) | |
712 | ||
713 | Make sure rdebugfs (which may be installed setuid or setgid disk) does | |
714 | not honor environment variables if euid != uid or egid != gid. | |
715 | ||
716 | Debugfs's ncheck command has been optimized and now is much more | |
717 | robust with faced with corrupted file systems. The ncheck command | |
718 | also now has a -c option which will verify the file type information | |
719 | in the directory entry to see if matches the inode's mode bits. This | |
720 | is extremely useful when trying to use debugsfs to determine which | |
721 | parts of the file system metadata can be trusted. | |
722 | ||
723 | E2image will try to use ftruncate64() to set the i_size for raw | |
724 | images, instead of writing a single null byte. This avoid allocating | |
725 | an extra block to the raw image, for those file systems and/or | |
726 | operating systems that support this. (Linux does.) In addition, fix | |
727 | a logic bug that caused the file to not be properly extended if the | |
728 | size of the last hole was exactly an multiple of a megabyte. | |
729 | ||
730 | Fixed a bug in resize2fs where for 1k and 2k file systems, where | |
731 | s_first_data_block is non-zero, this wasn't taken into account when | |
732 | calculate the minimum file system size for use with the -M option. | |
733 | ||
734 | Fixed the badblocks program to honor the -s flag when in read-only -t | |
735 | mode. (Addresses Debian Bug #646629) | |
736 | ||
737 | Update Czech, Dutch, French, Polish, and Sweedish translation from the | |
738 | Translation Project. | |
739 | ||
740 | Fixed various Debian Packaging issues so that dpkg-buildflags is used | |
741 | if present, which allows e2fsprogs to be built with security hardening | |
742 | flags. (Addresses Debian Bugs: #654457) | |
743 | ||
744 | Programmer's Notes | |
745 | ------------------ | |
746 | ||
747 | Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps. | |
748 | This was only an issue for programs compiled against e2fsprogs 1.41 | |
749 | that manipulate bitmaps directly. (Addresses Sourceforge Bugs: | |
750 | #3451486) | |
751 | ||
752 | The libext2fs library now uses sysconf() to fetch the page size, instead | |
753 | of the deprecated getpagesize(). | |
754 | ||
755 | The ext2fs_get_pathname() function will return a partial path if an a | |
756 | directory in the path is not a directory, displaying it as an inode | |
757 | number in angle brackets instead of giving up and displaying an error. | |
758 | This is much more helpful when a user is trying to debug a corrupted | |
759 | file system. | |
760 | ||
761 | Codepoints for the RO_COMPAT_REPLICA feature has been reserved. | |
762 | ||
763 | Added a new library function, ext2fs_file_get_inode_num(), for use by | |
764 | fuse2fs. | |
765 | ||
766 | Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a | |
767 | file, it actually works. | |
768 | ||
769 | The block iterator now properly honors the BLOCK_ABORT flag for | |
770 | extent-based flags. Previously, it didn't, which generally made code | |
771 | be less efficient, but it could cause bugs in ext2fs_link(), for | |
772 | example, by causing it to insert multiple directory entries. | |
773 | ||
774 | Fixed an (harmless other than causing a compiler warning) use of an | |
775 | uninitialized variable in e2fsck's MMP code. | |
776 | ||

778 | E2fsprogs 1.42 (November 29, 2011) |
779 | ================================== | |
c0b3deb5 | 780 | |
c2ac6c5f TT |
781 | This release of e2fsprogs has support for file systems > 16TB. Online |
782 | resize requires kernel support which will hopefully be in Linux | |
783 | version 3.2. Offline support is not yet available for > 16TB file | |
784 | systems, but will be coming. | |
c0b3deb5 | 785 | |
2406de54 TT |
786 | This release of e2fsprogs has support for clustered allocation. This |
787 | reduces the number of block (now cluster) bitmaps by allocating and | |
788 | deallocating space in contiguous power-of-2 collections of blocks, | |
789 | which are called clustered. This is a file system level feature, | |
790 | called 'bigalloc', which must be enabled when the file system is | |
791 | initially formatted. It is not backwards compatible with older | |
792 | kernels. | |
793 | ||
8a0ef9ed TT |
794 | Added support for the Multi-Mount Protection (MMP) feature. |
795 | ||
499d5ec5 TT |
796 | E2fsck more efficiently uses scratch files for really big file |
797 | systems. (This is a feature that has to be turned on explicitly; see | |
798 | [scratch_files] in the e2fsck.conf man page.) | |
799 | ||
c0b3deb5 TT |
800 | Fix a bug in e2fsck where if the free blocks and inodes counts are |
801 | incorrect, e2fsck would fix them without printing an error message. | |
802 | This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without | |
803 | any explanation of what was fixed. | |
804 | ||
805 | E2fsck will no longer attempt to clone an extended attribute block in | |
806 | pass1b handling if the file system does not support extended | |
807 | attributes. | |
808 | ||
809 | E2fsck will be more careful accidentally asking the user to continue | |
810 | if the file system is mounted, so that an escape sequence won't cause | |
811 | a false positive. (Addresses Debian Bug: #619859) | |
812 | ||
813 | E2fsck now uses less cpu time in pass 5 when large portions of the | |
814 | bitmaps are uninitialized. | |
815 | ||
816 | E2fsck will no longer segault when a corrupted file system has a bad | |
817 | extent, and removing it leads to a block needing to be deallocated. | |
818 | (Addresses SourceForge Bug: #2971800) | |
819 | ||
2406de54 TT |
820 | E2fsck will catch termination signals (segfaults, bus errors, sigfpe) |
821 | and print debugging information to make it easier to find potential | |
822 | problems. | |
823 | ||
c2ac6c5f TT |
824 | E2fsck will check to see if the bad block inode looks insane, and will |
825 | skip trying to use if it certain fields which should be zero look | |
826 | non-zero. This is to avoid a corrupted bad block inode causing e2fsck | |
827 | to get confused and do more harm than good. | |
828 | ||
829 | If e2fsck modifies certain superblock fields which the kernel doesn't | |
830 | look at, it will now mark the superblock as dirty without marking the | |
831 | file system as changed. This avoids signalling the init scripts that | |
832 | a reboot is necessary, since the kernel isn't going to look at those | |
833 | fields, so it won't care if they have been changed. | |
834 | ||
2406de54 TT |
835 | Fixed a bug in the libext2fs library (in the binary search routine of |
836 | the icount abstraction) that could (very, very rarely) cause e2fsck to | |
837 | die in the middle of pass 1 or pass 2 processing. | |
838 | ||
839 | E2fsck will not try to do a discard operation if the -n option was | |
840 | specified on the command line. | |
841 | ||
c0b3deb5 TT |
842 | E2fsck now supports an extended "discard" option which will cause |
843 | e2fsck to attempt discard all unused blocks after a full, successful | |
844 | file system check. | |
845 | ||
c2ac6c5f TT |
846 | E2fsck will check for the bad block inode to make sure it looks sane |
847 | before trusting it, to avoid causing more harm than good to the file | |
848 | system. | |
849 | ||
3a4ab830 TT |
850 | E2fsck now returns additional status bits in its exit code if it |
851 | aborts early in the e2fsck run. | |
852 | ||
499d5ec5 TT |
853 | E2fsck now correctly calculates the maximum file size in the case of |
854 | the huge_file file system feature enabled without extents. | |
855 | ||
2406de54 TT |
856 | The mke2fs and e2fsck programs now tries to use the punch hole command |
857 | as a "discard" when operating on normal files. | |
858 | ||
c0b3deb5 TT |
859 | The e2image program now supports the qcow2 format, which is a more |
860 | efficient way of capturing file system dumps. | |
861 | ||
862 | Mke2fs now supports the [devices] stanza in mke2fs.conf which allows | |
863 | per-device defaults to be specified in the configuration file. | |
864 | ||
865 | Mke2fs now supports the reserved_ratio relation in the [defaults] and | |
866 | [fs_types] section in mke2fs.conf. | |
867 | ||
868 | Mke2fs now creates extent-mapped directories for the root and | |
869 | lost+found directories. | |
870 | ||
871 | Mke2fs will skip zero'ing the journal if the extended option | |
872 | "lazy_journal_init" is specified. This can save a lot of time, but it | |
873 | does add a small amount of risk if the system crashes before the | |
874 | journal is overwritten entirely once. It is epsecially useful for | |
875 | testing. | |
876 | ||
877 | Mke2fs will now create file systems that enable user namespace | |
878 | extended attributes and with time- and mount count-based file | |
879 | system checks disabled. | |
880 | ||
881 | Mke2fs will not set a stride or strip size of one block based on block | |
882 | device attributes obtained from sysfs. | |
883 | ||
884 | Mke2fs now displays a progress report during the discard process. | |
885 | ||
886 | Mke2fs now handles extreme file system parameters correctly which | |
887 | previously caused the inodes per group to drop below 8, leading to a | |
888 | segfault. (The inodes per group must be a multiple of 8, but the code | |
889 | didn't correctly deal with an inodes per group count less than 8.) | |
890 | ||
2406de54 TT |
891 | Mke2fs and tune2fs previously would give an error if the user tried |
892 | setting the stride and stripe-width parameters to zero; but this is | |
893 | necessary to disable the stride and stripe-width settings. So allow | |
894 | setting these superblock fields to zero. (Addresses Google Bug: | |
895 | #4988557) | |
896 | ||
897 | Mke2fs now gives a warning if the auto-detected block size exceeds the | |
898 | system's page size. | |
899 | ||
c2ac6c5f TT |
900 | If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which |
901 | is the default), mke2fs will now set the s_max_mnt_count superblock | |
902 | field to -1, instead of 0. Kernels older then 3.0 will print a | |
903 | spurious message on each mount then they see a s_max_mnt_count set to | |
904 | 0, which will annoy users. (Addresses Debian Bug: #632637) | |
905 | ||
fd7c37fe TT |
906 | The default mke2fs.conf now has entries for "big" and "huge", which |
907 | are needed for very big file systems. | |
908 | ||
2406de54 TT |
909 | The resize2fs program now has support for a new online resize ioctl |
910 | that can support file systems > 16TB, once it arrives in v3.x kernels. | |
911 | ||
6b967cd6 TT |
912 | Fixed bug which caused resize2fs to fail when shrinking an empty file |
913 | system down to its minimal size. (Addresses Sourceforge Bug #3404051) | |
914 | ||
2406de54 TT |
915 | Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667) |
916 | ||
8a0ef9ed TT |
917 | Allow tune2fs to remove external journals if the device can not be |
918 | found. | |
919 | ||
c0b3deb5 TT |
920 | Debugfs's icheck will now correctly find inodes which use the |
921 | searched-for block as an extended attribute block. | |
922 | ||
923 | Debugfs now has a new "punch" command which remove blocks from the | |
924 | middle of an inode. | |
925 | ||
3a4ab830 TT |
926 | Debugfs now has a new "e2freefrag" command which analyzes the free |
927 | space fragmentation of the file system, using the same code as the | |
928 | e2freefrag program. | |
929 | ||
930 | Debugfs now has a "filefrag" command which displays information about | |
931 | a file's fragmentation. | |
932 | ||
933 | Add support to build a metadata-only, read-only, stripped-down version | |
934 | of debugfs called rdebugfs. | |
935 | ||
936 | Fixed a potential stack overrun bug in debugfs. | |
937 | ||
c0b3deb5 TT |
938 | The badblocks program now correctly recovers from I/O errors when |
939 | direct I/O is being used. The badblocks command now also supports a | |
940 | -B option which forces the use of buffered I/O, and the -v option will | |
941 | provide a more detailed breakdown of read, write, and failed | |
942 | comparison errors. | |
943 | ||
944 | Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl. | |
945 | ||
946 | Added support for journals larger than 2GB. | |
947 | ||
948 | Support using both hard links and symlinks when installing e2fsprogs. | |
949 | ||
950 | Add overflow checking to tune2fs -i's fsck interval, which must fit in | |
951 | a 32-bit field. | |
952 | ||
2406de54 TT |
953 | The debugfs command now has a new 'blocks' command which prints out |
954 | data blocks of a particular inode in a format which is useful for | |
955 | scripting. | |
956 | ||
c0b3deb5 TT |
957 | Filefrag will report 0 extents correctly in verbose mode. (Addresses |
958 | RedHat Bugzilla: #653234) | |
959 | ||
3871db6d | 960 | Filefrag has been fixed so its -v report prints the correct expected |
c2ac6c5f TT |
961 | block number (previously there had been an off-by-one error). In |
962 | addition, it will now display the number of contiguous extents when -v | |
963 | is not specified. This makes it consistent with the number of extents | |
964 | printed when the -v option was specified. In addition, the number of | |
965 | contiguous extents is far more interesting/useful than the number of | |
966 | physical extents for very large files. (Addresses Debian Bug: | |
3871db6d | 967 | #631498, #644792) |
c2ac6c5f | 968 | |
c0b3deb5 TT |
969 | Logsave's usage message has been fixed. (Addresses Debian Bug: |
970 | #619788) | |
971 | ||
3a4ab830 TT |
972 | Avoid an infinite loop in ext2fs_find_block_device() if there are |
973 | symlink loops in /dev caused by a buggy udev. | |
974 | ||
c0b3deb5 TT |
975 | Added a useful "fallocate" program to the contrib directory. |
976 | ||
2406de54 TT |
977 | Fixed an ABI compatibility problem in libext2fs which broke the dump |
978 | program. Also added back some macros which dump needed so it could | |
979 | compile against the latest version of ext2_fs.h (Addresses Debian Bug: | |
980 | #636418) | |
981 | ||
982 | Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses | |
983 | Debian Bug: #641667) | |
984 | ||
fd7c37fe TT |
985 | Added internationalization support for libcom_err error table strings. |
986 | ||
3871db6d TT |
987 | Fixed various spelling mistakes found in various output strings found |
988 | by I18N translators. | |
989 | ||
c0b3deb5 | 990 | Update translations: French, Chinese, Germany, Indonesian, Swedish, |

1000 | Programmer's Notes |
1001 | ------------------ | |
c0b3deb5 | 1002 | |
7becb206 TT |
1003 | Initial support for quota as an integrated feature, where the quota |
1004 | files are hidden system files that are automatically maintained by | |
1005 | e2fsck is present, although disabled by default. It must be enabled | |
1006 | by using the configure option --enable-quota. | |
1007 | ||
2406de54 TT |
1008 | Reserved the on-disk fields for the metadata checksum and snapshot |
1009 | features, which are currently in development. | |
1010 | ||
c0b3deb5 TT |
1011 | The ext2fs library now has the new functions ext2fs_punch(), |
1012 | ext2fs_get_memzero() and ext2fs_file_get_inode(). | |
1013 | ||
2406de54 TT |
1014 | The ext2fs library now has support for calculating the crc32c checksum |
1015 | (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le). | |
1016 | ||
c0b3deb5 TT |
1017 | The I/O manager now supports the discard operation. |
1018 | ||
1019 | Reserved file system code points for new 1st class quota feature. | |
1020 | ||
8a0ef9ed TT |
1021 | Shortened the compilation lines by moving the autoconf defines to |
1022 | a config.h header file. | |
1023 | ||
c0b3deb5 TT |
1024 | Fixed a potential free of an unitialized pointer in |
1025 | ext2fs_update_bb_inode(). | |
1026 | ||
8a0ef9ed | 1027 | Fixed miscellaneous gcc -Wall and coverity warnings. |
c0b3deb5 | 1028 | |
fd7c37fe | 1029 | Fixed portability issues for Mac OS X, Hurd, and FreeBSD. |
c0b3deb5 TT |
1030 | |
1031 | Fixed a build failure when OMIT_COM_ERR is defined. | |
1032 | ||
1033 | Improved error checking and fixed memory leaks caused by error return | |
1034 | paths. | |
1035 | ||
8a0ef9ed TT |
1036 | Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow |
1037 | the fsync() to be skipped. | |
1038 | ||
2406de54 | 1039 | Added a test for extent-mapped journals by mke2fs and tune2fs. |
c0b3deb5 TT |
1040 | |
1041 | Added a test for creating a large (over 4GB) journal using mke2fs. | |
1042 | ||
2406de54 TT |
1043 | Added a test to make sure the inode size remains constant. |
1044 | ||
1045 | The regression test script now prints the list of which tests failed. | |
1046 | ||
1047 | The regression test system now uses /tmp for its scratch files, which | |
1048 | is often a tmpfs mounted file system and hence much faster. | |
1049 | ||
1050 | The i_e2image test was fixed so it works with valgrind. | |
1051 | ||
1052 | Tests that rely on debugfs are now skipped if debugfs wasn't built. | |
1053 | ||
c0b3deb5 TT |
1054 | Fixed the dependencies for "make check" so all required dependencies |
1055 | are built before running the gression tests. | |
1056 | ||
1057 | A link to com_err.h is installed in $(includedir) during a "make install". | |
1058 | ||
fd7c37fe TT |
1059 | The po/*.gmo files are automatically rebuilt if they are missing or |
1060 | out of date. This helps out Debian packaging. | |
1061 | ||
6b967cd6 TT |
1062 | Allow ext2fs_get_memalign() to compile on systems that don't have |
1063 | posix_memalign(). | |
1064 | ||
3a4ab830 TT |
1065 | Fixed a namespace leak in libext2fs (tdb_null). |
1066 | ||
c0b3deb5 | 1067 | |
7267e3d3 TT |
1068 | E2fsprogs 1.41.14 (December 22, 2010) |
1069 | ===================================== | |
1070 | ||
1071 | Fix spurious complaint in mke2fs where it would complain if the file | |
1072 | system type "default" is not defined in mke2fs.conf. | |
1073 | ||
1074 | The resize2fs program will no longer clear the resize_inode feature | |
1075 | when the number reserved group descriptor blocks reaches zero. This | |
1076 | allows for subsequent shrinks of the file system to work cleanly for | |
1077 | flex_bg file systems. | |
1078 | ||
1079 | The resize2fs program now handles devices which are exactly 16T; | |
1080 | previously it would give an error saying that the file system was too | |
1081 | big. | |
1082 | ||
1083 | E2fsck (and the libext2fs library) will not use the extended rec_len | |
1084 | encoding for file systems whose block size is less than 64k, for | |
1085 | consistency with the kernel. | |
1086 | ||
1087 | Programming notes | |
1088 | ----------------- | |
1089 | ||
1090 | E2fsprogs 1.41.13 would not compile on big-endian systems. This has | |
1091 | been fixed. (Addresses Sourceforge Bug: #3138115) | |
1092 | ||
1093 | The ext2fs_block_iterator2() function passed an incorrect ref_offset | |
1094 | to its callback function in the case of sparse files. (Addresses | |
1095 | Sourceforge Bug: #3081087) | |
1096 | ||
1097 | Fix some type-punning warnings generated by newer versions of gcc. | |
1098 | ||
1099 | ||
d085f61f | 1100 | E2fsprogs 1.41.13 (December 13, 2010) |
d5b8a1e9 TT |
1101 | ===================================== |
1102 | ||
d085f61f TT |
1103 | E2fsck now supports the extended option "-E journal_only", which |
1104 | causes it to only do a journal replay. This is useful for scripts | |
1105 | that want to first replay the journal and then check to see if it | |
1106 | contains errors. | |
1107 | ||
1108 | E2fsck will now support UUID= and LABEL= specifiers for the -j option | |
1109 | (which specifies where to find the external journal). (Addresses | |
1110 | Debian Bug #559315) | |
1111 | ||
1112 | E2fsck now has support for the problems/<problem code>/force_no | |
1113 | configuration option in e2fsck.conf, which forces a problem to not be | |
1114 | fixed. | |
1115 | ||
1116 | Dumpe2fs will now avoid printing large negative offsets for the bitmap | |
1117 | blocks and instead print a message which is a bit more helpful for | |
1118 | flex_bg file systems. | |
1119 | ||
1120 | Mke2fs will now check the file system type (specified with the -t | |
1121 | option) to make sure it is defined in the mke2fs.conf file; if it is | |
1122 | not, it will print an error and abort. If the usage type (specified | |
1123 | with the -T option) is not defined in mke2fs.conf, mke2fs will print a | |
1124 | warning but will continue. (Addresses Debian Bug #594609) | |
1125 | ||
1126 | Clarified error message from resize2fs clarifying that on-line | |
1127 | shrinking is not supported at all. (Addresses Debian Bug #599786) | |
1128 | ||
1129 | Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be | |
1130 | displayed. (Addresses Debian Bug #555456) | |
1131 | ||
d5b8a1e9 TT |
1132 | E2fsck will open the external journal in exclusive mode, to prevent |
1133 | the journal from getting truncated while it is in use due to a user | |
1134 | accidentally trying to run e2fsck on a snapshotted file system volume. | |
d085f61f | 1135 | (Addresses Debian Bug #587531) |
d5b8a1e9 TT |
1136 | |
1137 | Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL | |
1138 | flag. | |
1139 | ||
1140 | The tune2fs program can now set the uninit_bg feature without | |
1141 | requiring an fsck. | |
1142 | ||
1143 | The tune2fs, dumpe2fs, and debugfs programs now support the new ext4 | |
1144 | default mount options settings which were added in 2.6.35. | |
1145 | ||
1146 | The e2fsck and dumpe2fs programs now support the new ext4 superblock | |
1147 | fields which track where and when the first and most recent file | |
1148 | system errors occurred. These fields are displayed by dumpe2fs and | |
1149 | cleared by e2fsck. These new superblock fields were added in 2.6.36. | |
1150 | ||
1151 | Debugfs now uses a more concicse format for listing extents in its | |
1152 | stat command. This format also includes the interior extent tree | |
1153 | blocks, which previously was missing from stat's output for | |
1154 | extent-based files. | |
1155 | ||
1156 | Debugfs has a new option, -D, which will request Direct I/O access of | |
1157 | the file system. | |
1158 | ||
1159 | Mke2fs will skip initializing the inode table if a device supports | |
1160 | discard and the discard operation will result in zero'ed blocks. | |
1161 | ||
1162 | Badblocks will now correctly backspace over UTF-8 characters when | |
1163 | displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses | |
1164 | Debian Bugs #583782 and #587834) | |
1165 | ||
1166 | E2freefrag will now display the total number of free extents. | |
1167 | ||
1168 | Resize2fs -P no longer requires a freshly checked filesystem before | |
1169 | printing the minimum resize size. | |
1170 | ||
1171 | Fixed a floating point precision error in a binary tree search routine | |
1172 | that can lead to seg fault in e2fsck and resize2fs. | |
1173 | ||
1174 | Fixed a bug in e2fsck where if both the original and backup superblock | |
1175 | are invalid in some way, e2fsck will fail going back to the original | |
1176 | superblock because it didn't close the backup superblock first, and | |
1177 | the exclusive open prevented the file system from being reopened. | |
1178 | ||
1179 | Fixed a big in e2freefrag which caused getopt parsing to fail on | |
1180 | architectures with unsigned chars. (Addresses Gentoo Bug: #299386) | |
1181 | ||
1182 | Clarified an mke2fs error message so a missed common in an -E option | |
1183 | (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1") | |
1184 | results in a more understandable explanation to the user. | |
1185 | ||
1186 | Mke2fs now displays the correct valid inode ratio range when | |
1187 | complaining about an invalid inode ratio specified by the user. | |
1188 | ||
1189 | Mke2fs now understands the extended option "discard" and "nodiscard", | |
1190 | and the older option -K is deprecated. The default of whether | |
1191 | discards are enabled by default can be controled by the mke2fs.conf | |
1192 | file. | |
1193 | ||
1194 | Mke2fs's handling of logical and physical sector sizes has been | |
1195 | improved to reflect the fact that there will be some SSD's with 8k and | |
1196 | 16k physical sectors arriving soon. Mke2fs will no longer force block | |
1197 | size to be the physical sector size, since there will be devices where | |
1198 | the physical sector size is larger than the system's page size, and | |
1199 | hence larger than the maximal supported block size. In addition, if | |
1200 | the minimal and optimal io size are not exported by the device, and | |
1201 | the physical sector size is larger than the block size, the physical | |
1202 | sector size will be used to set the Raid I/O optimization hints in the | |
1203 | superblock. | |
1204 | ||
1205 | E2fsck will now display a better, more specific error message when the | |
1206 | user enters a typo'ed device name, instead of blathering on about | |
1207 | alternate superblocks. | |
1208 | ||
1209 | Fixed various Debian Packaging Issues | |

1252 | Resize2fs -P will now refuse to print a minimum size if the file | |
1253 | system is not clean. Previously it would go ahead and print a minimum | |
1254 | size anyway, which might not be correct, leading to user confusion. | |
1255 | ||
1256 | E2fsck now tests for extents that begin at physical block 0 and | |
1257 | rejects them as invalid. (Addresses Google Bug: #2573806) | |
1258 | ||
1259 | Fixed a bug in e2fsck which could cause it to crash when trying to | |
1260 | remove an invalid extent and the block bitmaps hadn't yet been loaded. | |
1261 | (Addresses SourceForge Bug: #2971800) | |
1262 | ||
1263 | E2fsck now will completely skip time-based checks if the system clock | |
1264 | looks insane or the option broken_system_clock is set in | |
1265 | /etc/e2fsck.conf. | |
1266 | ||
1267 | E2fsck would previously report an i_blocks corruption for a 4T file | |
1268 | created using posix_fallocate; this bug has been fixed. | |
1269 | ||
1270 | E2fsck will now correctly mark a sparse journal as invalid and will | |
1271 | delete and recreate the journal to address the problem. | |
1272 | ||
1273 | E2fsck would previously incorrectly ask the user whether she would | |
1274 | like to abort the file system check after finding a problem --- and | |
1275 | then abort regardless of the user's answer. This is annoying, and | |
1276 | has been fixed. | |
1277 | ||
1278 | E2fsck can now continue even if it fails to recreate the resize | |
1279 | inode; previously it would just abort the file system check | |
1280 | altogether. | |
1281 | ||
1282 | E2fsck could potentially remove directory entries for inodes found in | |
1283 | the unused region of the inode table; this would generally happen on | |
1284 | ext4 file systems that do not use journaling. This bug has been fixed | |
1285 | by not clearing these directory entries once it has been established | |
1286 | that bg_unused_inodes may not be trustworthy; once pass #2 has been | |
1287 | completed, e2fsck will restart the file system check from the | |
1288 | beginning, and then it will be safe to delete any directory entries | |
1289 | pointing to inodes that appear to be deleted. (Addresses Google Bug: | |
1290 | #2642165) | |
1291 | ||
1292 | E2fsck will not try to set the block group checksums if the user | |
1293 | cancels the fsck with a control-C. It's a bad idea to set the | |
1294 | checksums if e2fsck hasn't been completed, and it often results an the | |
1295 | error message, "Inode bitmap not loaded while setting block group | |
1296 | checksum info". (Addresses Launchpad Bug: #582035) | |
1297 | ||
1298 | The mke2fs program now queries the kernel for the physical as well as | |
1299 | the logical sector size, and will not allow a blocksize below the | |
1300 | logical, and will strongly encourage a blocksize at least as big as | |
1301 | the physical blocksize. This is needed for 4k sector drives that | |
1302 | emulate 512 byte sector sizes. | |
1303 | ||
1304 | Mke2fs will now allow a flex_bg size of 1. This is unusual, and | |
1305 | rarely needed, but it is a legal value. | |
1306 | ||
1307 | E2fsck will check for cases where the EOFBLOCKS_FL is set when it is | |
1308 | not needed, and offer to clear it; this is a sign of a kernel bug, but | |
1309 | more importantly, some released kernels may crash when this situation | |
1310 | is encountered on ext4 file systems. (Addresses Google Bug: #2604224) | |
1311 | ||
1312 | E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether | |
1313 | i_size is correct. (Kernels starting with 2.6.34 will set | |
1314 | EOFBLOCKS_FL.) | |
1315 | ||
1316 | The com_err library will now only output ^M (a CR character) when the | |
1317 | tty is in raw mode. | |
1318 | ||
1319 | Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish, | |
1320 | and Vietnamese translations. | |
1321 | ||

1326 | Programmer's Notes | |
1327 | ------------------ | |
1328 | ||
1329 | The regression test suite now uses its own mke2fs.conf file, so that | |
1330 | downstream distributions want change the mke2fs.conf file which is | |
1331 | distributed in the RPM or dpkg file, without worrying about screwing | |
1332 | up the regression test results. | |
1333 | ||
1334 | Always build namei.o so that building with configure --disable-debugfs | |
1335 | works correctly. Long-term, if we care about reduced e2fsprogs | |
1336 | builds, we need a more general solution for deciding what .o files are | |
1337 | needed for a particular build. Given that install floppies are going | |
1338 | (gone?) the way the dodo bird, we probably don't care, though. | |
1339 | (Addresses Sourceforge Bug: #2911433) | |
1340 | ||
1341 | Add configure options --enable-symlink-build and | |
1342 | --enable-symlink-install, which allow e2fsprogs be built using | |
1343 | symlinks instad of hard links, and to be installed using symlinks | |
1344 | instead of hard links, respectively. It is useful when the file | |
1345 | system where the build is taking place, or the file system where | |
1346 | e2fsprogs is installed, can't handle hard links for some reason. | |

1352 | E2fsprogs 1.41.11 (March 14, 2010) |
1353 | ================================== | |
1354 | ||
1355 | E2fsck will no longer give a fatal error and abort if the physical | |
1356 | device has been resized beyond 2**32 blocks. (Addresses Launchpad | |
1357 | Bug: #521648) | |
1358 | ||
1359 | Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows | |
1360 | the allocation status of the block <blk>. (Addresses Debian Bug: | |
1361 | #564084) | |
1362 | ||
1363 | E2fsck now prints a much more emphatic and hopefully scary message | |
1364 | when a file system is detected as mounted while doing a read/write | |
1365 | check of the filesystem. Hopefully this will dissuade users from | |
1366 | thinking, "surely that message doesn't apply to *me*" :-( | |
1367 | ||
1368 | E2fsck -n will now always open the file system read-only. We now | |
1369 | disallow certain combination of options which previously were manual | |
1370 | exceptions; this is bad because it causes users to think they are | |
1371 | smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n | |
1372 | -D" are no longer supported. (Addresses Launchpad Bug: #537483) | |
1373 | ||
1374 | In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if | |
1375 | it detected a badly aligned partition. Unfortunately, this broke some | |
1376 | distribution installation scripts, so it now just prints the warning | |
1377 | message and proceeds. (Addresses Red Hat Bug: #569021. Addresses | |
1378 | Launchpad Bug: #530071) | |
1379 | ||
1380 | Mke2fs would take a long time to create very large journal files for | |
1381 | ext4. This was caused by a bug in ext2fs_block_iterate2(), which is | |
1382 | now fixed. | |
1383 | ||
1384 | E2fsck now understands the EOFBLOCKS_FL flag which will be used in | |
1385 | 2.6.34 kernels to make e2fsck not complain about blocks deliberately | |
1386 | fallocated() beyond an inode's i_size. | |
1387 | ||
1388 | E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where | |
1389 | e2fsck -fD can corrupt non-indexed directories when are exists one or | |
1390 | more file names which alphabetically sort before ".". This can happen | |
1391 | with ext2 filesystems or for small directories (take less than a lock) | |
1392 | which contain filenames that begin with a space or some other | |
1393 | punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad | |

1408 | E2fsprogs 1.41.10 (February 7, 2010) |
1409 | ==================================== | |
1410 | ||
1411 | Fix resize2fs bug which causes it to access invalid memory. | |
1412 | ||
1413 | Add libss support for libreadline.so.6. | |
1414 | ||
1415 | Fix e2fsck's check for extent-mapped directory with an incorrect file | |
1416 | type. | |
1417 | ||
1418 | Add new e2fsck.conf configuration option, default/broken_system_clock | |
1419 | to support systems with broken CMOS hardware clocks. Also, since too | |
1420 | many distributions seem to have broken virtualization scripts now, | |
1421 | e2fsck will by default accept dates which are off by up to 24 hours by | |
1422 | default. (Addresses Debian Bugs: #559776, #557636) | |
1423 | ||
1424 | Fix a bug where mke2fs may not use the best placement of the inode | |
1425 | table when there is only room for a single block group in the last | |
1426 | flex_bg. | |
1427 | ||
1428 | E2fsck is now smarter when it needs to allocate blocks in the course | |
1429 | of fixing file system problems. This reduces the number of spurious | |
1430 | differences found in pass #5. | |
1431 | ||
1432 | E2fsck will no longer rehash directories which fit in a single | |
1433 | directory block. | |
1434 | ||
1435 | E2fsck now correctly handles holes in extent-mapped directories (i.e., | |
1436 | sparse directories which use extents). | |
1437 | ||
1438 | Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2(). | |
1439 | ||
1440 | Fix a bug in filefrag where on platforms which can allow file systems | |
1441 | with 8k blocks, that it doesn't core dump when it sees a file system | |
1442 | with 8k block sizes. (Thanks to Mikulas Patocka for pointing this | |
1443 | out.) | |
1444 | ||
1445 | E2fsck will correctly fix directories that are have an inaccurate | |
1446 | i_size as well as other problems in a single pass, instead of | |
1447 | requiring two e2fsck runs before the file system is fully fixed. | |
1448 | ||
1449 | Fix e2fsck so it will correctly find and detect duplicate directory | |
1450 | entries for non-indexed directories. ( Addresses Sourceforge Bug: | |
1451 | #2862551) | |
1452 | ||
1453 | Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or | |
1454 | thinly-provisioned storage device. This can be disabled using the -K | |
1455 | option. | |
1456 | ||
1457 | Enhance libext2fs so it works around bug in Linux version 2.6.19 | |
1458 | and earlier where the /proc/swaps file was missing the header on | |
1459 | the first line. | |
1460 | ||
1461 | Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file | |
1462 | was missing the header on the first line. | |
1463 | ||
1464 | Fix some big-endian bugs in e2fsck and libext2fs. | |
1465 | ||
1466 | Fix resize2fs so it works correctly on file systems with external | |
1467 | journals instead of failing early with the error "Illegal inode | |
1468 | number". | |
1469 | ||
1470 | Fix libss so that it does not seg fault when using a readline library | |
1471 | which does not supply a readline_shutdown() function. | |
1472 | ||
1473 | Updated dumpe2fs's usage message so it correctly gives the right | |
1474 | arguments summary for "-o superblock=<num>" and "-o blocksize=<num>". | |
1475 | (Addresses Launchpad Bug: #448099) | |
1476 | ||
1477 | Teach libext2fs to ignore the high 32 bits of the i_blocks field | |
1478 | when huge_file file system feature is set, but the inode does not | |
1479 | have the HUGE_FILE_FL flag set. | |
1480 | ||
1481 | Fix e2fsck's handling of 64-bit i_blocks fields. | |
1482 | ||
1483 | E2fsck will now print "Illegal indirect block", "Illegal | |
1484 | double-indirect block", etc., instead of "Illegal block #-1" or | |
1485 | "Illegal block #-2", etc. This makes it easier for users to | |
1486 | understand what has gone wrong. (Addresses SourceForge Bug: #2871782) | |
1487 | ||
1488 | Mke2fs now will obtain get device topology information from blkid and | |
1489 | use it to populate the superblock stride and stripe sizes. It will | |
1490 | also warn if the block device is misaligned | |
1491 | ||
1492 | Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug: | |
1493 | ##524526) | |
1494 | ||
1495 | Fix the libext2fs library code to round up the bitmap size to a 4-byte | |
1496 | boundary, to prevent spurious seg faults caused by the x86 | |
1497 | architecture. This doesn't affect Linux systems, but was a major | |
1498 | problem on a number of *BSD systems. (Addresses Sourceforge Bug: | |
1499 | #2328708) | |
1500 | ||
1501 | Fix resize2fs's minimum size required for a file system so it doesn't | |
1502 | fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131) | |
1503 | ||
1504 | Dumpe2fs now prints summary information about the contents of the | |
1505 | journal. | |
1506 | ||
1507 | Avoid printing scary error messages when e2fsck starts running | |
1508 | problems on low-memory systems, as it tends to panic and mislead the | |
1509 | user. (Addresses Debian Bug: #509529) | |
1510 | ||
1511 | Fix blkid's modules.dep parser so it handles compressed (.ko.gz) | |
1512 | modules files. (Address Red Hat Bug: #518572) | |
1513 | ||
1514 | Fix tune2fs so it can add a journal when an extent-enabled file system | |
1515 | is mounted. (Addresses Launchpad bug: #416648) | |
1516 | ||
1517 | Update Czech, Indonesian, Polish and Vietnamese translations (from the | |

1526 | ------------------ | |
1527 | ||
1528 | The configure script supports the --with-cc, --with-ccopts, and | |
1529 | --with-ldopts options. Instead, the more standard use of CC=, | |
1530 | CCFLAGS=, and LDFLAGS= in the configure command line is used instead. | |
1531 | Also, --with-ld, which never worked, was also removed. | |
1532 | (Addresses Sourceforge Bug: #2843248) | |
1533 | ||
1534 | The in-tree header files are only used if the in-tree uuid or blkid | |

1543 | E2fsprogs 1.41.9 (August 22, 2009) |
1544 | ================================== | |
1545 | ||
1546 | Fix a bug in e2fsck routines for reallocating an inode table which | |
1547 | could cause it to loop forever on an ext4 filesystem with the FLEX_BG | |
1548 | filesystem feature with a relatively rare (and specific) filesystem | |
1549 | corruption. This fix causes e2fsck to try to find space for a new | |
1550 | portion of the inode table in the containing flex_bg, and if that | |
1551 | fails, the new portion of the inode table will be allocated in any | |
1552 | free space available in the filesystem. | |
1553 | ||
1554 | Make e2fsck less annoying by only asking for permission to relocate a | |
1555 | block group's inode table once, instead of for every overlapping | |
1556 | block. Similarly, only ask once to recompute the block group | |
1557 | checksums, instead of once for each corrupted block group's checksum. | |
1558 | ||
1559 | Fix filefrag to avoid print the extent header if the FIEMAP ioctl is | |
1560 | not present, and it needs to fall back to using the FIBMAP ioctl. | |
1561 | ||
1562 | Fix filefrag to correctly print the number of extents for zero-length | |
1563 | files. (Addresses Debian Bug: #540376) | |
1564 | ||
1565 | Filefrag now has a -B option which forces the use of the FIBMAP ioctl | |
1566 | to more easily debug the FIBMAP code. | |
1567 | ||
1568 | Fixed filefrag for non-extent based files. | |
1569 | ||
1570 | Add a new program, e2freefrag, which displays information about the | |
1571 | free space fragmentation in an ext2/3/4 filesystem. | |
1572 | ||
1573 | Fix inode resizing via tune2fs -I so that it works correctly in the | |
1574 | face of non-empty bad blocks inodes, and if the filesystem was | |
1575 | formatted using the "mke2fs -E stride=N" option for RAID arrays. | |
776a374a TT |
1576 | |
1577 | Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail | |
1578 | and corrupt large directories if the directory needs to shrink by more | |
1579 | than one block. (Addresses Debian Bug: #537510) | |
1580 | ||
1581 | Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or | |
1582 | last mount times are in the future, they are corrected even if | |
1583 | buggy_init_scripts is set. This is needed because otherwise resize2fs | |
1584 | will refuse to resize the filesystem, even after running "e2fsck -f". | |
1585 | (Addresses Launchpad bug: #373409) | |
edde3e51 TT |
1586 | |
1587 | E2fsck will now print much fuller information when the last mount time | |

1589 | believe their distribution has buggy init scripts, or they have a | |
1590 | failed CMOS/RTS clock battery. | |
1591 | ||

1634 | the uuidd work directory. | |
1635 | ||
1636 | Add safety checks (for non-Linux systems) so that uuidd isn't run with | |
1637 | file descriptors 0, 1, and 2 closed; and if they are closed, uuidd | |
1638 | will be careful not to close the file descriptor for its unix domain | |
1639 | socket when it detaches itself from the controlling tty. Also add | |
1640 | safety checks so that if the unix domain socket between the uuid | |
1641 | library and uuidd program is closed for any reason, both the library | |
1642 | and the uuidd will return an appropriate error code instead of looping | |
1643 | in an infinite loop. | |

1659 | Programmer's Notes | |
1660 | ------------------ | |
1661 | ||
1662 | Fix compilation problem when configured with --disable-uuid. | |
1663 | ||
1664 | Don't build uuidgen if configured with --disable-uuid. | |
1665 | ||
989a01f8 TT |
1666 | Add the new library function ext2fs_test_inode_bitmap_range(), and |
1667 | optimized ext2fs_test_block_bitmap_range(), which will be needed for | |
1668 | future optimizations for e2fsck. | |
1669 | ||
24a24cc6 TT |
1670 | Fix makefile dependencies for libcom_err so that the Makefiles work |
1671 | well on non-GNU make program. (Addresses Sourceforge Patches: #2813809) | |
1672 | ||
1673 | Enhance the build system so that the full set of commands executed by | |
1674 | the Makefiles are displayed, instead of the Linux kernel summary | |
1675 | output, if the build was configured with --enable-verbose-makecmds, or | |
1676 | if GNU make is in use and the V variable is non-null, i.e., via "make | |
1677 | V=1". | |

1680 | E2fsprogs 1.41.7 (June 29, 2009) |
1681 | ================================ | |
1682 | ||
1683 | Fix a bug in libext2fs which can cause e2fsck and resize2fs to write | |
1684 | uninitalized data into the portion of the inode beyond the first 128 | |
1685 | bytes when operating on inodes mapped via extents; potentially | |
1686 | corrupting filesystems. | |
1687 | ||
1688 | Fix memory leaks in e2fsprogs, including a very large memory leak | |
1689 | which can cause e2fsck to run out of memory when checking very large | |
1690 | filesystems using extents. | |
1691 | ||
1692 | The logsave program will now filter out the ^A and ^B characters when | |
1693 | writing to the console. | |
1694 | ||
1695 | Harden ext2fs_validate_entry() so that lsdel will not read beyond the | |
1696 | end of the block even if the directory block is corrupted. | |
1697 | ||
1698 | Fix debugfs from core dumping if the logdump command fails to open the | |
1699 | output file. | |
1700 | ||
1701 | Enhance badblocks to print the currently tested block number when | |
1702 | interrupted with ^C. | |
1703 | ||
1704 | Fix lsattr to exit with a non-zero status when it encounters errors. | |
1705 | (Addresses RedHat Bugzilla #489841) | |
1706 | ||
1707 | Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger) | |
1708 | filesystems as the kernel when encoding rec_len >= 64k. For 64k | |
1709 | filesystems (currently all that is supported by e2fsprogs, this is | |
1710 | only a minor corner case). | |
1711 | ||
1712 | Resize2fs will now update the journal backup fileds in the sup0erblock | |
1713 | if the journal is moved; this avoids an unnecessary full fsck after | |
1714 | resizing the filesystem. (Addresses RedHat Bugzilla: #505339) | |
1715 | ||
1716 | Fix libext2fs to properly initialize i_extra_size when creating the | |
1717 | journal and resize inodes. | |
1718 | ||
1719 | Change badblocks to allow block sizes larger than 4k. | |
1720 | ||
1721 | Fix filefrag progam so it correctly checks for errors from the fiemap ioctl. | |
1722 | ||
1723 | Update Chinese and Czech translation from the Translation Project. | |
1724 | ||
1725 | Clean up various man pages. (Addresses Debian Bug #531385 and #523063) | |
1726 | ||
1727 | ||
1728 | Programmer's Notes | |
1729 | ------------------ | |
1730 | ||
1731 | Add --disable-libuuid option to configure which uses an in-system | |
1732 | installed version of libuuid; the private version is enabled by | |
1733 | default. | |
1734 | ||
1735 | Add --valgrind-leakcheck option to the test_script program which runs | |
1736 | valgrind with the appropriate options to find memory leaks. | |
1737 | ||

1739 | E2fsprogs 1.41.6 (May 30, 2009) |
1740 | =============================== | |
1741 | ||
1742 | Fix a critical regression in e2fsck introduced version 1.41.5 which | |
1743 | can undo updates to the block group descriptors after a journal replay. | |
1744 | ||
1745 | If e2fsck receives an I/O error while replaying the journal, prompt | |
1746 | the user whether they want to ignore the error or not; if e2fsck is | |
1747 | run in preen mode, force fsck to abort the preen pass. | |
1748 | ||
1749 | Fix a bug which would cause e2fsck to core dump if the filesystem | |
1750 | contains a corrupt extent header, and the user declines to clear the | |
1751 | inode. (Addresses Sourceforge Bug: #2791794) | |
1752 | ||
1753 | Fix e2fsck to restart only once in the case of multiple block groups | |
1754 | which inodes in use that are in the uninitialized part of the block | |
1755 | group's inode table. | |
1756 | ||
1757 | To reduce user confusion, if the /etc/mtab file is missing | |
1758 | ext2fs_check_mount_point and ext2fs_check_if_mounted will return a | |
1759 | new, explicit error code to indicate this case. This will cause | |
1760 | e2fsck to give a clearer error message when the user is using buggy | |
1761 | rescue CD's that don't properly set up /etc/mtab. (Addresses Debian | |
1762 | Bug: #527859) | |
1763 | ||
1764 | Fix e2fsck so that if the primary group descriptors are corrupted, but | |
1765 | the backup superblock is entirely invalid, to go back to using (and | |
1766 | fixing) the priary group descriptors instead of completely giving up | |
1767 | on the filesystem. (Addresses Debian Bug: #516820) | |
1768 | ||
1769 | Change e2fsck to not abort a preen pass if an inode is found to have | |
1770 | i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer | |
1771 | kernels (post 2.6.29) will ignore this field. So let's fix it | |
1772 | automatically during the preen pass instead of forcing the user to fix | |
1773 | this up manually. (Addresses Debian Bug: #526524) | |
1774 | ||
1775 | Add resource tracking for e2fsck passes 1b through 1d. | |
1776 | ||
1777 | Speed up e2fsck by eliminating unnecessary journal checks if the | |
1778 | filesystem is already mounted and doesn't need recovery (since the | |
1779 | kernel would have run the journal when the filesystem was mounted.) | |
1780 | Also speed up e2fsck by avoiding unnecessary block group descriptor | |
1781 | updates in ext2fs_close(). | |
1782 | ||
1783 | Add support to chattr to migrate inodes from using direct/indirect | |
1784 | blocks to extents. | |
1785 | ||
1786 | Avoid corrupting the filesystem if there is an attempt to shrink a | |
1787 | filesystem using resize2fs smaller than posible by making | |
1788 | ext2fs_set_bmap() more careful not to delete the old block until the | |
1789 | new block can be inserted. In addition, fix a bug in how the minimum | |
1790 | size of the filesystem (plus a safety margin) is calculated, and | |
1791 | modify resize2fs to refuse to shrink the filesystem below that minimum | |
1792 | size without the force flag. | |
1793 | ||
1794 | Teach blkid to try to figure out DM device names using take advantage | |
1795 | of information in sysfs when running on kernels (2.6.29 and later) | |
1796 | which provide this information in /sys/block/dm-<N>/dm/name; this is | |
1797 | much faster than scanning for the devncie number in /dev/mapper. | |
1798 | ||
1799 | Fix blkid to prefer /dev/mapper/<name> device names instad of the | |
1800 | private /dev/dm-X names. | |
1801 | ||
1802 | Add an -a option to debugfs's close_filesys command which writes any | |
1803 | changes to the superblock or block group descriptors to all of the | |
1804 | backup superblock locations. | |
1805 | ||
1806 | Add support to the filefrag program to use the FIEMAP ioctl. | |
1807 | ||
1808 | Update Chinese translation from the Translation Project. | |
1809 | ||
1810 | Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and | |
1811 | Launchpad Bug: #381854) | |
1812 | ||
1813 | Fixed various Debian packaging issues --- see debian/changelog for | |
1814 | details. (Addresses Debian Bug #506064) | |
1815 | ||
1816 | ||
1817 | Programmer's Notes | |
1818 | ------------------ | |
1819 | ||
1820 | Add test code to make sure e2fsck's problem.c doesn't have two problem | |
1821 | codes assigned to duplicate values. | |
1822 | ||
1823 | Avoid using a hard-coded path for /bin/rm in block's test_probe.in. | |
1824 | (Addresses Sourceforge Bug: #2780205) | |
1825 | ||
1826 | Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty | |
1827 | function declaration for init_resource_track() and | |
1828 | print_resource_track() when RESOURCE_TRACK is not defined. | |
1829 | ||
1830 | The test code which is used to build the tst_csum progam has been | |
1831 | moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to | |
1832 | avoid compile problems caused by not having a prototype for | |
1833 | ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331) | |
1834 | ||
1835 | Update the config.guess and config.sub file to the latest from the | |
1836 | FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses | |
1837 | Debian Bug: #528330) | |
1838 | ||
1839 | Add a new function, ext2fs_extent_open2(), which behaves like | |
1840 | pext2fs_extent_open(), but uses the user-supplied inode structure | |
1841 | when opening an extent instead of reading the inode from disk. | |
1842 | ||
1843 | ||
898ddb06 TT |
1844 | E2fsprogs 1.41.5 (April 23, 2009) |
1845 | ================================= | |
daf3c82d TT |
1846 | |
1847 | Fix a number of filesystem corruption bugs in resize2fs when growing | |
1848 | or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem | |
1849 | is not mounted). | |
1850 | ||
1851 | Debugfs can now set i_file_acl_high via the set_inodes_field command, | |
1852 | and print a 64-bit file acl. This is useful for debugging filesystem | |
898ddb06 TT |
1853 | corruptions where the high bits of i_file_acl_high are set. E2fsck |
1854 | will detect and fix non-zero i_file_acl_high on 32-bit filesystems | |
1855 | since some Linux kernel versions pay attention to this field even when | |
1856 | they shouldn't. | |
daf3c82d | 1857 | |
e60c25b0 TT |
1858 | Speed up e2fsck when checking clean filesystems by avoiding |
1859 | unnecessary block reads, and coalescing the block group descriptor | |
1860 | blocks so they are read using a single read operation. | |
1861 | ||
daf3c82d TT |
1862 | The libuuid library will now close all file descriptors before running |
1863 | uuidd. This avoids problems when the calling program has open sockets | |
1864 | which then never get closed because uuidd is a long-running helper | |
1865 | daeomn. (Addresses Launchpad bug: #305057) | |
1866 | ||
1867 | In order to avoid unnecessary full filesystem checks by e2fsck after | |
1868 | an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on | |
1869 | the backup superblocks. (Addresses Red Hat Bugzilla: #471925) | |
1870 | ||
1871 | Mke2fs will avoid trying to create the journal when run in | |
1872 | superblock-only mode (mke2fs -S), since the left-over journal in the | |
1873 | inode table will cause mke2fs to fail. | |
1874 | ||
e60c25b0 TT |
1875 | Fix a bug in libext2fs functions that check to see if a particular |
1876 | device or filesystem image is mounted, which would cause these | |
1877 | functions to report that a file identical to the (relative) pathname | |
1878 | used by a pseudo-filesystem was mounted when in fact it was not. | |
1879 | ||
daf3c82d TT |
1880 | Update Czech translation from the Translation Project. |
1881 | ||
e60c25b0 TT |
1882 | Add Chinese (simplified) translation from the Translation Project. |
1883 | ||
daf3c82d TT |
1884 | Fix support for external journals (which was broken in e2fsprogs |
1885 | 1.41.4). | |
1886 | ||
1887 | Fix a regression in debugfs where the "stat" command when no | |
1888 | filesystem was open would cause debugfs to crash with a segmentation | |
1889 | violation. | |
1890 | ||
1891 | Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be | |
1892 | used to support filesystems without a journal. Update the blkid | |
1893 | library so it understands this. | |
1894 | ||
e60c25b0 TT |
1895 | The blkid library will remove an entry from the blkid cache |
1896 | representing the entire disk if partitions are found, since presuambly | |
1897 | the device previously had no partition table, but has now transitioned | |
1898 | to using a partition table. | |
1899 | ||
daf3c82d TT |
1900 | Add a check to mke2fs and tune2fs that the argument to the -m option |
1901 | (which specifies the reserved ratio) must be greater than zero. | |
1902 | (Addresses Debian Bug: #517015) | |
1903 | ||
1904 | Add support for tracking the number kilobytes written to the | |
1905 | filesystem via the superblock field s_kbytes_written. It will be | |
1906 | updated by the kernel as well as by e2fsprogs programs which write to | |
1907 | the filesystem. This is useful for tracking the wear to filesystems | |
1908 | on Solid Sstate Drives. | |
1909 | ||
1910 | Fix compatibility issue in the libext2fs info file and makeinfo | |
1911 | version 4.12. (Addresses Red Hat Bugzilla: #481620) | |
1912 | ||
e60c25b0 | 1913 | Update/clarify man pages. (Addresses Debian Bug: #515693, #365619) |
daf3c82d TT |
1914 | |
1915 | Fixed various Debian packaging issues --- see debian/changelog for | |
1916 | details. (Addresses Debian Bug: #506279) | |
1917 | ||
1918 | Programmer's Notes | |
1919 | ------------------ | |
1920 | ||
1921 | Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian | |
1922 | Bug: #521602) | |
1923 | ||
1924 | Fix various gcc compilation warnings and other programming cleanups. | |
e60c25b0 | 1925 | (Addresses Red Hat Bugzilla: #486997) |
daf3c82d TT |
1926 | |
1927 | Add support for building the blkid command statically. | |
1928 | ||
e60c25b0 TT |
1929 | Add support for disabling the built-in blkid library in favor of a |
1930 | system-installed blkid implementation via the configure option | |
1931 | --disable-libblkid. | |
1932 | ||
daf3c82d | 1933 | |
b2ca48f4 TT |
1934 | E2fsprogs 1.41.4 (January 27, 2009) |
1935 | =================================== | |
1936 | ||
1937 | Fixed a bug which could sometimes cause blkid to return an exit value | |
1938 | of zero for a non-existent device (Addresses Debian Bug: #502541) | |
1939 | ||
1940 | Blkid will now recognize ext3 filesystems that have the test_fs flag | |
1941 | set as ext3 filesystems. | |
1942 | ||
1943 | The blkid library will now recognize btrfs filesystems and swap | |
1944 | devices currently used by user-level software suspend. | |
1945 | ||
1946 | Tune2fs now updates the block group checksums when changing the UUID | |
1947 | to avoid causing e2fsck to complain vociferously at the next reboot. | |
1948 | ||
1949 | Tune2fs's inode size resizing algorithms have been fixed so it is not | |
1950 | vastly inefficient for moderate-to-large filesystems, due to some | |
1951 | O(n**2) and O(n*m) algorithms that didn't scale well at all. | |
1952 | ||
1953 | Fix tune2fs's inode resizing algorithm so it will not corrupt | |
1954 | filesystems laid out for RAID filesystems; in addition, tune2fs will | |
1955 | refuse to change the inode size for filesystems that have the flex_bg | |
1956 | feature enabled. (This is a limitation in the current implementation | |
1957 | of tune2fs -I.) | |
1958 | ||
1959 | E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4 | |
1960 | filesystems with 32-bit block numbers, when the headers for 64-bit | |
1961 | block numbers was added. This regression has been fixed. | |
1962 | ||
1963 | Debugfs's ncheck command has been fixed to avoid printing garbage | |
1964 | characters at the end of file names. | |
1965 | ||
1966 | Fix resize2fs for ext4 filesystems. Some blocks that that need moving | |
1967 | when shrinking filesystems with uninit_bg feature would not be moved. | |
1968 | In addition, blocks and inode table blocks were not being correctly | |
1969 | freed when shrinking filesystems with the flex_bg feable, which caused | |
1970 | resize2fs -M to fail. Finally, when blocks are moved, make sure the | |
1971 | uninitialized flag in extents is preserved. | |
1972 | ||
1973 | Fix bug which caused dumpe2fs to abort with an error if run on a | |
1974 | filesystem that contained an external journal. | |
1975 | ||
1976 | Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check | |
1977 | for this in argv[0] to provide better legacy support for these | |
1978 | distributions. This is a practice that should NOT be continued, | |
1979 | however. | |
1980 | ||
1981 | Mke2fs now has a new option -U, which allows the user to specify the | |
1982 | UUID that should be used for the new filesystem. | |
1983 | ||
1984 | Mke2fs will treat devices that are exactly 16TB as if they were 16TB | |
1985 | minus one block. This allows users who have read that ext3 supports | |
1986 | up to 16TB filesystems and who create a 16TB LVM to not get confused, | |
1987 | since the true limit is really 16TB minus one block. | |
1988 | ||
1989 | E2fsck will no longer abort an fsck run if block group has an errant | |
1990 | INODE_UNINIT flag. | |
1991 | ||
1992 | E2fsck now distinguishes between fragmented directories and fragmented | |
1993 | files in verbose mode statistics and in the fragcheck report. | |
1994 | ||
1995 | Fix a bug in e2fsck which casued it double count non-contiguous | |
1996 | extent-based inodes. | |
1997 | ||
1998 | E2fsck will leave some slack space when repacking directories to allow | |
1999 | room for a few directory entries to be added without causing leaf | |
2000 | nodes to be split right away. | |
2001 | ||
2002 | Fix a bug which caused e2fsck to crash when it comes across a | |
2003 | corrupted interior node in an extent tree with the error message: | |
2004 | "Error1: Corrupt extent header on inode XXXXXX" | |
2005 | ||
2006 | E2fsck problem descriptions involving the journal are no longer | |
2007 | referred to as "ext3" problems, since ext4 filesystems also have | |
2008 | journals. | |
2009 | ||
2010 | Fix a long-standing bug in e2fsck which would cause it to crash when | |
2011 | replying journals for filesystems with block sizes greater than 8k. | |
2012 | ||
2013 | Update Catalan translation from the Translation Project. | |
2014 | ||
2015 | Fixed various Debian packaging issues --- see debian/changelog for | |
2016 | details. (Addresses Debian Bugs: #503057, #502323, #511207) | |
2017 | ||
2018 | Programmer's Notes | |
2019 | ------------------ | |
2020 | ||
2021 | Fix build of e2fsck.profiled, and add support for building profiled | |
2022 | binaries in the misc directory if configured with --enable-profile. | |
2023 | ||
2024 | The ext2fs_open() function now performs more sanity checks on the | |
2025 | superblock to avoid potential divide by zero errors by other parts of | |
2026 | library. | |
2027 | ||
2028 | The ext2fs_read_inode_full() function now has a safety check to avoid | |
2029 | a segmentation fault on corrupted filesystems. | |
2030 | ||
2031 | The ext2fs_new_inode() function now has a sanity check so that if the | |
2032 | s_first_inode field in the superblock is insane, it will return | |
2033 | EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number. | |
2034 | ||
2035 | To avoid segmentation faults, ext2fs_block_alloc_stats() and | |
2036 | ext2fs_inode_alloc_stats() now validates the passed inode or block | |
2037 | number to avoid overrunning an array boundary. | |
2038 | ||
2039 | Various signed/unsigned errors for variables containing block numbers | |
2040 | have been fixed. | |
2041 | ||
2042 | Accomodations for gcc's stupidity in not realizing that constant | |
2043 | strings that do not contain a '%' character are safe to use in format | |
2044 | strings have been made so that distributions that want to compile | |
2045 | e2fsprogs with -Werror=format-security have an easier time doing so. | |
2046 | ||
2047 | Added a new 64-bit getsize interface, ext2fs_get_device_size2(). | |
2048 | ||
2049 | Added the utility make-sparse.c to the contrib directory. | |
2050 | ||
2051 | The ext2fs_block_iterate2() function now reflects errors from | |
2052 | ext2fs_extent_set_bmap() to the caller, if the callback tries to | |
2053 | change a block on an extent-based file, and ext2fs_extent_set_bmap() | |
2054 | fails for some reason (for example, there isn't enough disk space to | |
2055 | split a node and expand the extent tree. | |
2056 | ||
2057 | The ext2fs_block_iterate2() function will preserve the uninit flag in | |
2058 | extents when the callback function modifies a block in an extent-based | |
2059 | file. | |
2060 | ||
2061 | E2fsck will now flag filesystems that have an insane s_first_ino field | |
2062 | in their superblock, and attempt to use a backup superblock to repair | |
2063 | the filesystem. | |

2067 | =================================== | |
2068 | ||
2069 | E2fsck has been fixed so it prints the correct inode number for | |
2070 | uinit_bg related problems. | |
2071 | ||
2072 | E2fsck will now offer to clear the test_fs flag if the ext4 filesystem | |
2073 | is available on linux. This can be disabled via a configuration | |
2074 | option in /etc/e2fsck.conf. | |
2075 | ||
2076 | Fix a file descriptor leak in libblkid when checking to see if an ext4 | |
2077 | or ext4dev module exists. | |
2078 | ||
2079 | Fix a bug in e2fsck where in preen mode, if there are disk I/O errors | |
2080 | while trying to close a filesystem can lead to infinite loops. | |
2081 | (Addresses Red Hat Bugzilla #465679) | |
2082 | ||
2083 | Fix a bug in resize2fs where passing in a bogus new size of 0 blocks | |
2084 | will cause resize2fs to drop into an infinite loop. (Addresses Red | |
2085 | Hat Bugzilla: #465984) | |
2086 | ||
2087 | Add a check in the Unix I/O functions in libext2fs so that when a | |
2088 | device is opened read/write, return an error if the device is | |
2089 | read-only using the BLKROGET ioctl. | |
2090 | ||
2091 | Fix debugfs's ncheck command so that it prints all of the names of | |
2092 | hardlinks in the same directory. | |
2093 | ||
2094 | Fix a bug in libblkid so it correctly detects whether the ext4 and | |
2095 | ext4dev filesystems are available, so that the ext4dev->ext4 | |
2096 | fallback code works correctly. | |

2101 | Fix a parallel build problem by making sure util/subst is built before | |
2102 | trying to build the lib/et directory. (Addresses Sourceforge Bug: | |

2108 | E2fsprogs 1.41.2 (October 2, 2008) |
2109 | ================================== | |
2110 | ||
2111 | Fix e2fsck's automatic blocksize detection. This fixes a regression | |
2112 | from e2fsprogs 1.40.7 which caused e2fsck to fail if the user | |
2113 | specifies a block number using the -b option if the blocksize option | |
2114 | isn't also specified using -B. Unfortunately, users very commonly | |
2115 | invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup | |
2116 | superblock; in fack e2fsck will often suggest this kind of command | |
2117 | line. Oops. | |
2118 | ||
2119 | Enhance the debugfs's "ncheck" command so it will print all of the | |
2120 | pathnames for the specified inodes. (Previously, in some cases ncheck | |
2121 | might not print a pathname for an inode at all if some of the other | |
2122 | inodes had multiple hard links.) | |
2123 | ||
2124 | Enhance debugfs's "hash" command so the hash seed can be specified via | |
2125 | a command-line option. In addition, allow the hash algorithm to be | |
2126 | specified by name instead of just by number. | |
2127 | ||
2128 | Fix e2fsck so that we don't accidentally print the translation file's | |
2129 | header when asking the user a custom question so there is no prompt | |
2130 | defined for a particular problem record. For example, the question | |
2131 | "Run journal anyway" will get the PO header tacked on because e2fsck | |
2132 | erroneously passed the null string to _(). (Addresses Launchpad Bug: | |
2133 | #246892) | |
2134 | ||
2135 | Enhance badblocks so that it can test a normal file which is greater | |
2136 | than 2GB. | |
2137 | ||
2138 | Enhance the badblocks command so that it displays the time and | |
2139 | percentage complete when in verbose mode. (Addresses Debian Bug: | |
2140 | #429739) | |
2141 | ||
2142 | Fix a potential memory leak in a error handling path in debugfs's | |
2143 | ncheck function. | |
2144 | ||
2145 | Fix a potential memory corruption problem if a memory allocation fails | |
2146 | in resize2fs. | |
2147 | ||
2148 | Fix the usage message for debugfs's logdump command to be consistent | |
2149 | with its man manpage. | |
2150 | ||
2151 | Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech, | |
2152 | and Sweedish translation from the Translation Project. | |
2153 | ||
2154 | Add documentation for the file I/O functions to the libext2fs.texinfo | |
2155 | file. (Addresses Debian Bug: #484877) | |
2156 | ||
2157 | Update and clarified various man pages. (Addresses Launchpad Bug | |
2158 | #275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103) | |
2159 | ||
2160 | Fixed various Debian packaging issues --- see debian/changelog for | |
2161 | details. (Addresses Debian Bug: #497619) | |
2162 | ||
2163 | Programmer's Notes | |
2164 | ------------------ | |
2165 | ||
2166 | Fix a potential file descriptor leack in libcom_err by setting the | |
2167 | close-on-exec flag for a fd used for debugging. (Addresses Red Hat | |
2168 | Bugzilla #464689) | |
2169 | ||
2170 | Fix a potential race in libcom_err by using sem_post/sem_init. SuSE | |
2171 | has been carrying a patch for a long time to prevent a largely | |
2172 | theoretical race condition if a multi-threaded application adds and | |
2173 | removes error tables in multiple threads. Unfortunately SuSE's | |
2174 | approach breaks compatibility by forcing applications to link and | |
2175 | compile with the -pthread option; using pthread mutexes has | |
2176 | historically been problematic. We fix this by using sem_post/sem_init | |
2177 | instead. | |
2178 | ||
2179 | Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses | |
2180 | Sourceforge Bug: #2087502) | |
2181 | ||
2182 | Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded | |
2183 | libraries when using ELF shared libraries. | |
2184 | ||
2185 | Fix ELF shared library when building on systems that don't already | |
2186 | have the e2fsprogs shared libraries already installed. (Addresses | |
2187 | Sourceforge Bug: #2088537) | |
2188 | ||
2189 | Fix the pkg-config files so they work correctly when linking with | |
2190 | static libraries and fix the include directory so programs don't have | |
2191 | to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h> | |
2192 | instead. (Addresses Sourceforge Bug: #2089537) | |
2193 | ||
2194 | Make sure ext2fs_swab64() is compiled for all platforms, and not just | |
2195 | for x86. (Addresses Debian Bug: #497515) | |
2196 | ||
2197 | Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all | |
2198 | non-x86 platforms. (They had been removed for x86 earlier.) | |
2199 | ||
2200 | Fix diet libc compilation support, which had bitrotted due to lack of | |
2201 | TLC. Fixing this improves general portability. | |
2202 | ||
2203 | When installing the link library when using ELF shared libraries, | |
2204 | avoid using absolute pathnames if the link library and the shared | |
2205 | library are installed in the same directory. (Addresses Sourceforge | |
2206 | Bug: #1782913) | |
2207 | ||
2208 | Fix gen-tarball so it will work even if the top-level directory has | |
2209 | been renamed to something other than "e2fsprogs". Also make | |
2210 | gen-tarball print the size of the resulting tar.gz file. | |

2213 | E2fsprogs 1.41.1 (September 1, 2008) |
2214 | ==================================== | |
30ab7f4c TT |
2215 | |
2216 | Many people are forgetting to update their mke2fs.conf file, and this | |
2217 | causes ext3, ext4, and ext4dev filesystems won't get created with the | |
2218 | proper features enabled. We address this in two ways. First, mke2fs | |
2219 | will issue a warning if there is not definition for an ext3, ext4, or | |
2220 | ext4dev filesystem and the user is trying to create such a filesystem | |
2221 | type. Secondly, when installing from a source build, "make install" | |
2222 | will provide basic configuration file handling for /etc/mke2fs.conf. | |
2223 | If it exists, and does not mention ext4dev, it will be moved aside to | |
2224 | /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will | |
2225 | be installed. If the existing /etc/mke2fs.conf file does mention | |
2226 | ext4dev, then "make install" will install official mke2fs.conf file as | |
2227 | /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that | |
2228 | they should look to see if any changes need to be merged. | |
2229 | ||
31d64878 TT |
2230 | The mke2fs program will now create the journal in the middle of the |
2231 | filesystem, since this minimizes seek times on average for fsync-heavy | |
2232 | workloads. In addition, mke2fs will now create journals using extents | |
2233 | for filesystems that support them. This results in a more efficient | |
2234 | encoding for the journal since it eliminates the need for using | |
2235 | indirect blocks. | |
2236 | ||
2237 | The mke2fs program will avoid allocating an extra block to the | |
2238 | journal. (Addresses Sourceforge Bug: #1483791) | |
2239 | ||
2240 | Mke2fs will correctly enforce the prohibition against features | |
2241 | (specifically read-only features) in revision 0 filesystems. (Thanks | |
2242 | to Benno Schulenberg for noticing this problem.) | |
2243 | ||
2244 | Mke2fs previously would occasionaly create some slightly non-optimally | |
2245 | placed inode tables; this bug has been fixed. | |
2246 | ||
2247 | The mke2fs and tune2fs programs now print the correct usage message | |
2248 | describing the maximum journal size. (Addresses Debian Bug: #491620) | |
2249 | ||
2250 | Add support for setting the default hash algorithm used in b-tree | |
2251 | directories in tune2fs (from a command-line option) or mke2fs (via | |
2252 | mke2fs.conf). In addition, change the default hash algorithm to | |
2253 | half_md4, since it is faster and better. | |
30ab7f4c TT |
2254 | |
2255 | The blkid library will now recognize MacOS hfsx filesystems, and | |
2256 | correctly extract the label and uuid for hfs, hfsx, and hfsplus | |
2257 | filesystems. (Addresses Sourceforge Feature Requests: #2060292) | |
2258 | ||
31d64878 TT |
2259 | The blkid library has improved detection of JFS and HPFS filesystems. |
2260 | (Addresses Launchpad Bug: #255255) | |
2261 | ||
2262 | The blkid library is now much more efficiently handling devicemapper | |
2263 | devices, mainly by no longer using the devicemapper library. This can | |
2264 | speed up access for systems with a large number of device mapper | |
2265 | devices. | |
2266 | ||
2267 | Blkid had a number of cache validation bugs in libblkid that have been | |
2268 | fixed. (Addresses Debian Bug: #493216) | |
2269 | ||
30ab7f4c TT |
2270 | Resize2fs will now properly close out the "updating inode references" |
2271 | progress bar so there is a newline printed before printing the final | |
2272 | "resize is successful" message. | |
2273 | ||
2274 | Resize2fs will now correctly handle filesystems with extents and/o | |
2275 | uninitialized block groups correctly when file/directory blocks need | |
2276 | to relocated (i.e., when shrinking a filesystem or if the resize_inode | |
2277 | is not present). To support this, the ext2fs library now supports | |
2278 | initializing inode and block bitmaps that are not yet initialized when | |
2279 | allocating them using ext2fs_new_block() and ext2fs_new_inode(). In | |
2280 | addition, e2fs_block_iterate2() can now support changing the location | |
2281 | of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has | |
2282 | been optimized to avoid creating unnecessary new extents when updating | |
2283 | the location of blocks in the extent tree. This will also help out | |
2284 | e2fsck's recovery of obscurely corrupted filesystems with extents, | |
2285 | when blocks are claimed by multiple inodes. | |
2286 | ||
31d64878 TT |
2287 | Add support for on-line resizing ext4 filesystem with the flex_bg |
2288 | filesystem feature. The method for doing so is not optimal, but to do | |
2289 | a better job will require kernel support. | |
2290 | ||
30ab7f4c TT |
2291 | E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and |
2292 | debugfs programs to not be able to read e2image files; the signed | |
2293 | vs. unsigned bug in the code which read bitmaps from the e2image has | |
2294 | been fixed. (Addresses Debian Bug: #495830) | |
2295 | ||
2296 | Resize2fs is now correctly managing the directory in-use counts when | |
2297 | shrinking filesystems and directory inodes needed to be moved from one | |
2298 | block group to another. This bug has been around since e2fsprogs | |
2299 | 1.26, and is largely harmless, but does cause a filesystem corruption | |
2300 | which will be flagged by e2fsck after the filesystem has been shrunk. | |
2301 | ||
2302 | E2fsck will no longer issue spurious complaints about the inode size | |
2303 | caused by very large extent-based files, and by blocks reallocated | |
2304 | using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses | |
2305 | Kernel Bugzilla: #11341) | |
2306 | ||
2307 | Mke2fs will now set the creation timestamp on the lost+found directory | |
2308 | and the root directory. (More generally, all new inodes created using | |
2309 | the ext2fs library will correctly set the creation timestamp.) | |
2310 | ||
2311 | E2fsck now correctly calculates ind/dind/tind statistics in the | |
2312 | presence of extent-based files. In addition, "e2fsck -v" will report | |
2313 | statistics of the depth of extent trees in the filesystem. E2fsck can | |
2314 | also give an inode fragmentation report using "e2fsck -E fragcheck" | |
2315 | which can be useful when debugging the kernel block allocation | |
2316 | routines. | |
2317 | ||
31d64878 TT |
2318 | Fix support for empty directory blocks in ext4 filesystems with 64k |
2319 | blocksize filesystems. | |
2320 | ||
2321 | E2fsck will now print the depth of corrupt htree directories. | |
30ab7f4c TT |
2322 | |
2323 | Debugfs's htree command now correctly understands extent-based | |
2324 | directories. It will also print out the minor hash as well as the | |
2325 | major hash. | |
2326 | ||
31d64878 TT |
2327 | Debugfs has a new command which will print the supported features of |
2328 | e2fsprogs, to enable scripts to know whether the installed version of | |
2329 | e2fsprogs can support a specific feature. | |
2330 | ||
2331 | Debugfs will now write files using extents for filesystems that | |
2332 | support them. | |
2333 | ||
30ab7f4c TT |
2334 | The error message printed by "tune2fs -I" if the inode size was too |
2335 | small was rather confusing, so it has been improved. Also, we won't | |
2336 | try to create an undo log until we know that command-line-specified | |
2337 | parameters such as "tune2fs -I <inode size>" are valid. | |
2338 | ||
30ab7f4c TT |
2339 | Given some filesystems found "in the wild" that had non-zero block |
2340 | group checksums even though the uninit_bg/gdt_sum feature was not | |
2341 | enabled, e2fsck would issue spurious error messages. Teach | |
2342 | ext2fs_group_desc_csum_verify() to ignore the block group checksum | |
2343 | entirely if the feature flag is not set. (Addresses Debian Bug: | |
2344 | #490637) | |
2345 | ||
2346 | The blkid program will now print out a user-friendly listing of all of | |
2347 | the block devices in the system and what they contain when given the | |
2348 | -L option. (Addresses Debian Bug: #490527) | |
2349 | ||
31d64878 TT |
2350 | The filefrag program now has a more accurate calculation for the |
2351 | number of ideal extents. (Addresses Debian Bug: #458306) | |
2352 | ||
2353 | The test I/O manager is now enabled by default, but its overhead is | |
2354 | only incurred when it would be enabled via the TEST_IO_FLAGS or | |
2355 | TEST_IO_BLOCK environment variables. | |
2356 | ||
30ab7f4c TT |
2357 | Typographical errors in various program strings and usage messages |
2358 | have been fixed; most of these were pointed out by the e2fsprogs | |
2359 | message catalog translators. (Thanks, translators!) | |
2360 | ||
2361 | Update and clarified various man pages, as well as some typographical | |
2362 | errors in the libext2fs texinfo file. | |
2363 | ||
2364 | Fixed various Debian packaging issues --- see debian/changelog for | |
2365 | details. | |
2366 | ||
2367 | Add Indonesian and update French, Polish, Dutch, German, Sweedish, | |
2368 | Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697, | |

2371 | Programmer's Notes | |
2372 | ------------------ | |
2373 | ||
2374 | Fix portability problem with the badblocks group; for systems that | |
2375 | don't have nanosleep(), try using usleep() instead. | |
2376 | ||
2377 | The "make check" target in the e2fsck directory now sets | |
2378 | LD_LIBRARY_PATH before running the various e2fsck internal library | |
2379 | regression tests. | |
2380 | ||
2381 | The crc32 regression test in the e2fsck library is now portable to | |
2382 | greater varienty of environments, including big-endian systems and | |
2383 | when cross-building e2fsprogs for embedded systems. (Addresses | |
2384 | Sourceforge Bug: #2019287) | |
2385 | ||
2386 | The ext2fs_extent_set_bmap() had some bugs when setting the first | |
2387 | block in a file, or when replacing a single block extent. Those cases | |
2388 | fortunately were came up relatively rarely when e2fsck was checking | |
2389 | files, but caused some problems when resize2fs was shrinking | |
2390 | extent-based files. | |
2391 | ||
31d64878 TT |
2392 | Fix a potential core-dumping bug in libe2p's iterate_on_dir() |
2393 | function. | |
2394 | ||
2395 | Various ext2fs library functions --- ext2fs_block_iterate2(), | |
2396 | ext2fs_initialize() and ext2fs_extent_open() --- now correctly free | |
2397 | allocated memory to avoid memory leaks in all of their error return | |
2398 | paths. | |
30ab7f4c TT |
2399 | |
2400 | Ext2ed was failing to build because masix support had been removed in | |
2401 | the rest of e2fsprogs, so ext2ed no longer has masix support, either. | |
2402 | ||
2403 | The configure script now respects the LDFLAGS environment variable if | |
2404 | it is set when configure is called. (Addresses Sourceforge Feature | |
2405 | Request: #1937287) | |
2406 | ||
2407 | Libuuid is now more portable to the Windows platform. (Addresses | |
2408 | Sourceforge Feature Request: #1937287) | |
2409 | ||
2410 | The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of | |
2411 | bare echo commands so that configure flags such as --quiet work | |
2412 | correctly. (Addresses Sourceforge Patches: #2058794) | |
2413 | ||
2414 | A few uses of sprintf have been removed from the ext2fs library to | |
2415 | make life easier for bootloaders with a limited libc environment. | |
2416 | (Addresses Sourceforge Bug: #2049120) | |
2417 | ||
2418 | The ext2fs_read_inode() checks the validity of the inode number passed | |
2419 | to it earlier, to avoid doing some needless work when it would fail | |
2420 | anyway. | |
2421 | ||
2422 | The ext2fs_open() checks the validity of the blocksize parameter | |
2423 | passed to it earlier, to avoid doing some needless work when it would | |
2424 | fail anyway. | |
2425 | ||
2426 | Disable a very annoying automatic "%.sh -> %" GNU make rule in the | |
2427 | top-level Makefile. That automatic rule is used to better support | |
2428 | SCCS, but it caused problems for a particular niche distribution which | |
2429 | likes to use configure.sh files to store the configure options used to | |
2430 | build a package. Unfortuntaely GNU make will use the configure.sh to | |
2431 | replace the configure script, resulting in a self-inflicted fork bomb | |
2432 | leading to an out-of-memory crash. | |
2433 | ||
31d64878 TT |
2434 | To support old GNU C compilers don't use C99/C++ comments, but only |
2435 | K&R style comments, and don't try to use __builtin_expect if __GNUC__ | |
2436 | is less than 3. (__builtin_expect is only supported for gcc versions | |
2437 | 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since | |
2438 | this is an optimization, we only try to use __builtin_expect for gcc 3 | |
2439 | and up.) | |
2440 | ||
2441 | In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of | |
2442 | __LITTLE_ENDIAN, which are only defined by glibc's header files and | |
2443 | hence isn't portable. | |
2444 | ||
2445 | For the convenience for some distributions that need a static tune2fs, | |
2446 | the Makefile for misc/ now has a tune2fs.static target. | |
2447 | ||
2448 | The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND | |
2449 | for extent-based files | |
2450 | ||
2451 | The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based | |
2452 | files. | |
2453 | ||
2454 | All source files no longer have any trailing white space. | |
2455 | ||
2456 | The io_channel_read_blk64() and io_channel_write_blk64() functions are | |
2457 | now functions instead of C preprocessor macros to provide better | |
2458 | forward compatibility. | |
2459 | ||
2460 | The e2fpsrogs translation template now expands the @x abbrevation. | |
2461 | ||
2462 | Various namespace leackages in libblkid, libe2p, and libext2fs have | |
2463 | been fixed. | |
2464 | ||
2465 | Fix a parallel build problem in e2fsprogs. | |
2466 | ||
30ab7f4c TT |
2467 | E2fsprogs is now more portable to Solaris. |
2468 | * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's | |
2469 | are always present. | |
2470 | * Scripts do not assume that /bin/true is always in /bin | |
2471 | * Don't use __FUNCTION__ since Solaris's C99 doesn't support it. | |
2472 | * Flush stdio handles before calling setbuf(), since Solaris will | |
2473 | discard any pending output to the stream. | |
2474 | * Define _XOPEN_SOURCE to 600 since Solaris's header files are very | |
2475 | picky about which C compiler can beused for SUSv3 conformance. | |
2476 | Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500), | |
2477 | and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600). | |
2478 | Since we need some SUSv3 functions, consistently use SUSv3 so | |
2479 | that e2fsprogs will build on Solaris using c99. | |
2480 | * Solaris C99 does not support varargs C preprocessor macros | |
2481 | * Solaris header files pollute the C namespace if in/netinet.h | |
2482 | is included, which conflicts with e2fsprogs' use of the kmem_cache_t | |
2483 | typedef. | |
2484 | * Solaris ships with a pathetically ancient shell in /bin/sh so we | |
2485 | avoid the use of various more avanced shell constructs such as $(). | |
2486 | ||
31d64878 TT |
2487 | The "make rpm" command will now take some extra configure optiosn from |
2488 | the build environment without needing to patch the source tree. | |
30ab7f4c | 2489 | |
31d64878 TT |
2490 | The ext2fs_add_dir_block() function will now grow the dblist more |
2491 | aggressively as an optimization to avoid copying the array too often. | |
30ab7f4c | 2492 | |
31d64878 TT |
2493 | The e2fsck_write_bitmaps() will write the block and inode bitmaps |
2494 | together instead of in two passes. | |

2497 | E2fsprogs 1.41 (July 10, 2008) |
2498 | ============================== | |
795de67f TT |
2499 | |
2500 | Add support for ext4 filesystem features, in particular extents, | |
2501 | uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add | |
2502 | support for checking journal checksums. Debugfs will print new | |
2503 | superblock and inode fields that were defined for ext4. For example, | |
2504 | the nanosecond and i_version fields of an inode, and the | |
2505 | s_min_extra_isize and s_wanted_extra_isize fields from the superblock. | |
2506 | Note: Resize2fs doesn't currently support the combination of flex_bg | |
2507 | and !resize_inode. (Addresses Debian Bug: #388452, #425477) | |
2508 | ||
2509 | Tune2fs can support migrating a filesystem from using 128 byte inodes | |
2510 | to 256 byte inodes, so it can take advantage of the full features of | |
2511 | ext4. | |
2512 | ||
2513 | Add support for "undo" support. E2fsck and mke2fs can optionally | |
2514 | record an undo log which can replayed by the program e2undo. | |
2515 | ||
92e49d85 TT |
2516 | E2fsck could damage a filesystem by trying to relocate inode tables |
2517 | due to corrupted block group descriptors, where the attempted inode | |
2518 | table relocation would do far more harm than good. E2fsck has been | |
2519 | fixed to detect this these sorts of corrupted block group descriptors | |
2520 | much earlier in e2fsck processing, so it can try to use the backup | |
2521 | superblock and block group descriptors first. This should be a much | |
2522 | better strategy for recovering these types of corrupted filesystems. | |
2523 | (Addresses Sourceforge Bug: #1840291) | |
2524 | ||
795de67f TT |
2525 | E2fsck will display a more understandable message when the last check |
2526 | field in the superblock is in the future. (Addresses Debian Bug: | |
2527 | #446005). | |
2528 | ||
92e49d85 TT |
2529 | E2fsck now performs more extensive and careful checks of extended |
2530 | attributes stored in the inode. | |
2531 | ||
a41d5ac8 TT |
2532 | Enhance mke2fs to print a more explanatory error message when |
2533 | ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug: | |
2534 | #488663) | |
2535 | ||
2536 | Fix mke2fs to use a default block size of 4k when formatting an | |
2537 | external journal device. This is done by using a fixed filesystem | |
2538 | type list that consists only of the single filesystem type "journal" | |
2539 | when looking up configuration keys in /etc/mke2fs.conf. (Addresses | |
2540 | Debian Bug: #488663) | |
2541 | ||
795de67f TT |
2542 | Speed up how mke2fs writes the journal data blocks by writing the disk |
2543 | blocks in larger chunks. | |
2544 | ||
a41d5ac8 TT |
2545 | Fix blkid handling of stale devices. Fix a bug which could cause a |
2546 | core dump while garbage collecting the blkid cache, and assure that | |
2547 | blkid_find_dev_with_tag() never returns a non-existent device. Also, | |
2548 | if a filesystem is found at a new /dev location, eliminate any | |
2549 | duplicate stale entries which can not be verified. | |
daf3c82d | 2550 | (Addresses Debian Bugs: #487758, #487783) |
a41d5ac8 | 2551 | |
795de67f TT |
2552 | Add more paranoid checks for LVM volumes and swap partitions in |
2553 | blkid's probe function, to reduce the chances of false positives. | |
2554 | ||
2555 | The mke2fs program now has a much more sophisticated system for | |
2556 | controlling configuration parameters of a newly created filesystem | |
2557 | based on a split filesystem and usage type system. The -t option to | |
2558 | mke2fs was a deprecated alias to -c; it now specifies a filesystem | |
2559 | type (ext2, ext3, ext4, etc.), while the -T option can now be a comma | |
2560 | separated usage list. The filesystem type information and type | |
2561 | information is used to extract configuration parameters from the | |
2562 | /etc/mke2fs.conf file. | |
2563 | ||
795de67f TT |
2564 | The mke2fs program will no longer complain and request the -f option |
2565 | when the user tries to create a filesystem with greater than 2**31 | |
2566 | blocks. | |
2567 | ||
92e49d85 TT |
2568 | When creating a filesystem for the GNU Hurd use a fs-type of Hurd and |
2569 | adjust the mke2fs.conf file so filesystems for the Hurd are created | |
2570 | with a blocksize of 4096 and inode size of 128, which is all it knows | |
2571 | how to handle. (Addresses Debian Bug: #471977) | |
2572 | ||
795de67f TT |
2573 | Mke2fs will always make sure that lost+found always has at least 2 |
2574 | blocks, even for filesystems with very large blocksizes (i.e., 64kb). | |
2575 | ||
92e49d85 TT |
2576 | Resize2fs will now print the minimum needed filesystem size if given |
2577 | the -P option, and will resize the filesystem to the smallest possible | |
2578 | size if given the -M option. | |
2579 | ||
2580 | Fix resize2fs to clean up the resize_inode if all of the reserved gdt | |
2581 | blocks are consumed during an off-line resize. | |
2582 | ||
795de67f TT |
2583 | The "ls" command in debugfs now supports the -p option, which causes |
2584 | it to quote the filenames so that spaces or tabs in directory entries | |
2585 | are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses | |
2586 | Sourceforge Feature Request: #1201667) | |
2587 | ||
2588 | Fix a potential off-by-one buffer oveflow in the fs_device_name in an | |
2589 | e2image file. | |
2590 | ||
2591 | The chattr program will return a non-zero exit code in case of | |
2592 | failures, and error messages can be suppressed with the -f option. | |
a41d5ac8 TT |
2593 | (Addresses Red Hat Bugzilla: #180596) |
2594 | ||
2595 | Fix a bug in badblocks which caused it to overrun an array and likely | |
2596 | crash if more than 8 test patterns are specified using the -t option. | |
2597 | (Addresses Debian Bug: #487298) | |
795de67f | 2598 | |
a41d5ac8 TT |
2599 | Add support to badblocks to limit how quickly it reads from the disk |
2600 | drive (so it can be used for background scrubbing), and so it will | |
2601 | abort after finding a given number of errors. | |
2602 | ||
795de67f TT |
2603 | Remove support for the legacy big-endian filesystem format which only |
2604 | existed on extremely long-dead PowerPC kernels almost a decade ago. | |
2605 | ||
2606 | Remove MASIX support from e2fsprogs. | |
2607 | ||
2608 | Add I/O statistics reporting to e2fsck. | |
2609 | ||
a41d5ac8 TT |
2610 | Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch, |
2611 | Czech translations. | |
2612 | ||
2613 | Fixed various Debian packaging issues --- see debian/changelog for | |
92e49d85 | 2614 | details. (Addresses Debian Bugs: #487443, #487675, #490003) |
a41d5ac8 TT |
2615 | |
2616 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |

2619 | Programmer's Notes |
2620 | ------------------ | |
2621 | ||
2622 | Factor out bitmap code in preparation for adding 64-bit new-style | |
2623 | bitmaps. | |
2624 | ||
2625 | Fix gcc -Wall warnings | |
2626 | ||
2627 | Fix the pkg-config files so that private librares are specified in | |
2628 | "Libs.private:". | |
2629 | ||
2630 | Fix the libext2fs.texinfo manual so it builds with modern versions of | |
2631 | texinfo. | |
2632 | ||
2633 | Silence the makefile from showing the awk command used to build the | |
2634 | ||
2635 | Clean up the badblocks group so to make it more portable and robust. | |
2636 | ||
2637 | Avoid using predictable filenames in /tmp in blkid's regression test | |
2638 | suite. Also remove bashism's in the regression test script. | |
2639 | ||
92e49d85 TT |
2640 | If the configure script is given --with-diet-libc, don't use thread |
2641 | local storage, since diet libc doesn't support TLS. (Addresses | |
2642 | Sourceforge Bug: #2000654) | |
2643 | ||
2644 | Fix the blkid regression test suite to tolerate older versions of | |
2645 | mkswap that don't support the -U option. | |
2646 | ||
795de67f TT |
2647 | A few library routines have been converted to support 64-bit block |
2648 | numbers; in particular, the I/O manager functions, the test_io, | |
2649 | inode_io, and unix_io managers have all be converted to support 64-bit | |
2650 | operation. | |
2651 | ||
2652 | Debugfs can now be extended for use by test programs. See | |
2653 | lib/ext2fs/extents.c for an example for how it can be used. The test | |
2654 | program links against the debugfs object files, and provides | |
2655 | additional commands by defining an auxiliary libss command table. | |
2656 | ||
2657 | The lazy_bg filesystem feature, which was only used by developer's | |
2658 | testing, has been removed since it has been largely supplanted by | |
2659 | uninit_bg. This also simplifies the code. | |

2666 | percentage of reserved blocks. (Addresses Debian Bug: #452639) | |
2667 | ||
2668 | Updated Spanish and Catalan translations. | |
2669 | ||

2682 | portable for older compilers. | |
2683 | ||
2684 | Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473) | |
2685 | ||

2690 | E2fsprogs 1.40.10 (May 21, 2008) |
2691 | ================================ | |
2692 | ||
2693 | When deciding whether or not to revalidate a blkid cache entry, if the | |
2694 | device's mtime is newer than the last time the cached entry was | |
2695 | validated, force a revalidation. | |
2696 | ||
2697 | Fix a potential data corruption bug in e2fsck in the journal replay. | |
2698 | The chances of this is happening is extremely remote, especially the | |
2699 | default data=ordered or data=writeback modes. However, if a block | |
2700 | which has been journalled starts with the first four bytes 0xc03b3998, | |
2701 | when e2fsck replays the journal, those four bytes will be replaced | |
2702 | with zero's. Fortunately, it is highly, highly unlikely for e2fsck | |
2703 | metadata to begin with those fatal 4 byte sequence, and unless | |
2704 | data=ordered mode is in use, data blocks are never journaled. | |
2705 | ||
2706 | Updated German, Dutch, Sweedish, and Vietnamese translations. | |
2707 | ||

2720 | |
2721 | SuSE's security team audited uuidd and came up with a few minor | |
2722 | issues. None of them are serious given that uuidd runs setuid as a | |
2723 | unprivileged user which has no special access other than libuuid | |
2724 | directory, but it's good to get them fixed. | |
2725 | ||
2726 | One additional fix in ext2fs_swap_inode_full() needed for resize2fs to | |
2727 | work correctly with in-inode extended attributes. | |

2740 | in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug: | |
2741 | #203323, Addresses Sourceforge Bug: #1926023) | |
2742 | ||
2743 | Fix fsck so that progress information is sent back correctly when | |
2744 | multiple filesystems are being check and the output of fsck is being | |
2745 | redirected to a file descriptor. Also, include the device name (w/o | |
2746 | spaces) in the progress information sent back via a file descriptor. | |
2747 | (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug: | |
2748 | #1926023) | |

2750 | Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems. | |
2751 | ||
2752 | If logsave receives a SIGTERM or SIGINT signal, it will now pass that | |
2753 | signal to its child process. | |
2754 | ||
2755 | Fix mke2fs's creation of are resize inode when there is a non-standard | |
2756 | s_first_data_block setting. | |
2757 | ||
2758 | Fix bug in blkid when run by an unprivileged user; most devices were | |
2759 | not reported correctly. 9Addresses Launchpad Bug: #220275) | |
2760 | ||
2761 | Mke2fs will not allow the logically incorect combination of | |
2762 | resize_inode and meta_bg, which had previously caused mke2fs to create | |
2763 | a corrupt fileystem. | |
2764 | ||

2788 | E2fsprogs 1.40.8 (March 13, 2008) |
2789 | ================================= | |
2790 | ||
2791 | Fixed e2image -I so it works on image files which are larger than 2GB. | |
2792 | ||
2793 | Fixed e2fsck's handling of directory inodes with a corrupt size field. If | |
2794 | the size is larger than the number of blocks found in the inode, don't | |
2795 | try to allocate extra empty blocks at the end of the directory to make | |
2796 | up the difference; there's no point to doing that. In addition, if | |
2797 | the size is not a multiple of a blocksize, always fix it. | |
2798 | ||
2799 | E2fsck handled a pass 2 "should never happen error" by not giving | |
2800 | enough information and then core dumping. Unfortunately, it was all | |
2801 | too easy to trigger the "should never happen" situation if a | |
2802 | directory's inode size was not correct. This has been fixed, but | |
2803 | e2fsck has also been taught how to handle this situation more | |
2804 | gracefully, by simply removing the inode hash tree information, so | |
2805 | that it can be rebuilt again after e2fsck's pass 3. (Addresses | |
2806 | Launchpad Bug: #129395) | |
2807 | ||
2808 | Resize2fs had a bug resizing large inodes with extended attributes | |
2809 | that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed | |
2810 | completely on big-endian systems such as PowerPC. The bug should be | |
2811 | completely fixed now. Yay for regression test suites. (Addresses Red | |
2812 | Hat Bugzilla: #434893) | |
2813 | ||
2814 | Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese | |

2816 | up to become the new German translation maintainer! (Addresses Debian | |
2817 | Bugs: #302512, #370247, #401092, #412882). | |
2818 | ||
2819 | When e2fsck is clearing a corrupt inode's HTREE directory information, | |
2820 | make it clear that it is just clearing the HTREE information, not the | |
2821 | entire inode. | |
2822 | ||
2823 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
2824 | ||
2825 | Programmer's notes | |
2826 | ------------------ | |
2827 | ||
2828 | Add new functions, ext2fs_dblist_get_last() and | |
2829 | ext2fs_dblist_drop_last(), which allows the caller to examine the last | |
2830 | directory block entry added to the list, and to drop if it necessary. | |
2831 | ||
2832 | Fixed a portability problem in libblkid with DJGPP. | |
2833 | ||
2834 | Fix an obvious typo in an "internal error" message in e2fsck. Thanks | |
2835 | to Philipp Thomas for pointing this out. | |

2841 | E2fsprogs 1.40.7 (February 28, 2008) |
2842 | ==================================== | |
2843 | ||
2844 | Remove support for clearing the SPARSE_SUPER feature from tune2fs, and | |
2845 | depreciate the -s option, since it can result in filesystems which | |
2846 | e2fsck can't fix easily. There are very good reasons for wanting to | |
2847 | disable sparse_super; users who wants to turn off sparse_super can use | |
2848 | debugfs. (Addresses Sourceforge Bug: #1840286) | |
2849 | ||
2850 | Add missing options to mke2fs's usage message. (Addresses Sourceforge | |
2851 | Bug: #1751393) | |
2852 | ||
2853 | Fix bug in resize2fs when large (greater than 128 byte) inodes are | |
2854 | moved when a filesystem is shrunk; it was only moving the first 128 | |
2855 | bytes, so extended attributes were not getting moved. (Addresses Red | |
2856 | Hat Bugzilla: #434893) | |
2857 | ||
2858 | E2fsck now prints an explicit message when the bad block inode is | |
2859 | updated, to avoid confusion about why the filesystem was modified. | |
2860 | (Addresses Sourceforge Bug: #756460) | |
2861 | ||
2862 | Allow mke2fs and tune2fs manipulate the large_file feature. | |
2863 | Previously we just let the kernel and e2fsck do this automatically, | |
2864 | but e2fsck will no longer automatically clear the large_file feature. | |
2865 | It still isn't really necessary to worry about this feature flag | |
2866 | explicitly, but some users seem to care. (Addresses Red Hat Bugzilla: | |
2867 | #258381) | |
2868 | ||
2869 | Suppress message about an old-style fstab if the fstab file is empty. | |
2870 | (Addresses Debian Bug: #468176) | |
2871 | ||
2872 | Fix (really minor) bug in debugfs's find_free_block so it avoids | |
2873 | reporting a free block more than once if there are too few free blocks | |
2874 | in the filesystem. (Addresses Sourceforge Bug: #1096315) | |
2875 | ||
2876 | Change e2fsck to no longer clear the LARGE_FILES feature flag | |
2877 | automatically, when there are no more > 2GB files in the filesystem. | |
2878 | It's been almost a decade since there have been kernels that don't | |
2879 | support this flag, and e2fsck clears it quietly without telling the | |
2880 | user why the filesystem has been changed. | |
2881 | ||
2882 | Fix bug which could cause libblkid to seg fault if a device mapper | |
2883 | volume disappears while it is being probed. (Addresses RedHat | |
2884 | Bugzilla: #433857) | |
2885 | ||
2886 | Inhance e2fsck's reporting of unsupported filesystem feature flags. | |
2887 | (Addresses Sourceforge Feature Request: #1175808) | |
2888 | ||
2889 | Fix option syntax in dumpe2fs for explicit superblock and blocksize | |
2890 | parameters. What was currently documented in the man page has been | |
2891 | broken for some time, due to getopt() implementation changes. The | |
2892 | option sytax has been changed to one which is can be more portable | |
2893 | supported and which is consistent with the format for extended options | |
2894 | in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994) | |
2895 | ||
2896 | Add support to tune2fs to clear the resize_inode feature. This | |
2897 | requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816) | |
2898 | ||
2899 | Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat | |
2900 | Bugzilla: #409321) | |
2901 | ||
2902 | Add support for setting RAID stride and stripe-width via mke2fs and | |
2903 | tune2fs. Teach dumpe2fs to print the RAID parameters. | |
2904 | ||
2905 | Add support for setting new superblock fields to debugfs's | |
2906 | set_super_value. | |
2907 | ||
2908 | Add support for printing "mostly-printable" extended attributes in | |
2909 | Debugfs. | |
2910 | ||
2911 | Add support for the -M option to fsck, which causes it to ignore | |
2912 | mounted filesystem. | |
2913 | ||
2914 | Fix uuidd so that it creates the pid file with the correct pid number. | |
2915 | (Addresses Sourceforge Bug: #1893244) | |
2916 | ||
2917 | Fix various gcc -Wall warnings. | |
2918 | ||
2919 | Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations | |
2920 | ||
2921 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
2922 | (Addresses Sourceforge Patch: #1399325) | |

2925 | Programmer's notes: | |
2926 | ------------------- | |
2927 | ||
2928 | Fixed various Debian packaging issues --- see debian/changelog for | |
2929 | details. (Addresses Debian Bug: #466929) | |
2930 | ||
2931 | Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a | |
2932 | partially filled-in filesystem object on an error, so that e2fsck can | |
2933 | print more intelligent error messages. | |
2934 | ||
2935 | Add a new function e2p_edit_feature2() which allows the caller to | |
2936 | specify which feature flags are OK to set or clear, and which returns | |
2937 | more specific information about feature flags which are not allowed to | |
2938 | be set/cleared. | |
2939 | ||
2940 | Set the C locale in the test_script driver since it uses [A-Za-z]. | |
2941 | (Addresses Sourceforge Bug: #1890526) | |
2942 | ||
2943 | Use fcntl locking instead of lockf in libuuid since Cygwin doesn't | |
2944 | support lockf(). | |
2945 | ||
2946 | Change configure.in to avoid using the 'dc' command unless it is | |
2947 | absolutely needed. (i.e., when using parsing a WIP-style version | |
2948 | number) (Addresses Sourceforge Bug: #1893024) | |
2949 | ||
2950 | Add portability checks to support compilation under DJGPP. | |
2951 | ||
2952 | Update to the latest samba tdb code before the LGPLv3 change, which | |
2953 | fixes a realloc() leak on failure. | |
2954 | ||
2955 | Fix memory leak in ext2fs_alloc_block(). | |
2956 | ||
2957 | Fix makefile dependency issues for various install targets. | |
2958 | (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456) | |
2959 | ||
2960 | Improve descriptions for the r_move_itable and r_resize_inode tests. | |

2963 | E2fsprogs 1.40.6 (February 9, 2008) |
2964 | =================================== | |
2965 | ||
2966 | Add support for returning labels for UDF filesystems in the blkid | |
2967 | library. | |
2968 | ||
2969 | Fix bug in the blkid library where cached filesystems was not being | |
2970 | flushed when opening USB devices returned the error ENOMEDIUM. | |
2971 | (Addresses Debian Bug: #463787) | |
2972 | ||
2973 | Added logic to the blkid library to automatically choose whether a | |
2974 | filesystem should be mounted as ext4 or ext4dev, as appropriate. | |
2975 | ||
2976 | Allow tune2fs to set and clear the test_fs flag on ext4 filesystems. | |
2977 | ||
2978 | Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been | |
2979 | configured with --enable-jbd-debug. | |
2980 | ||
2981 | Document the BLKID_FILE environment variable in the libblkid man page | |
2982 | ||
2983 | Programmer's Notes: | |
2984 | ------------------- | |
2985 | ||
2986 | Update e2fsprogs translation template and Vietnamese and Czech translations | |
2987 | ||
2988 | Fixed various Debian packaging issues --- see debian/changelog for | |
2989 | details. (Addresses Debian Bugs: #436058) | |
2990 | ||
2991 | Don't try to create $DESTDIR/etc/init.d as part of make install as we | |
2992 | don't install the init.d script (and it's not the recommended way to | |
2993 | start uuidd anyway). (Addresses Sourceforge Bug: #1885085) | |
2994 | ||
2995 | Use thread local storage to fix a theoretical race condition if two | |
2996 | threads try to format an unknown error code at the same time in the | |
2997 | com_err library. | |
2998 | ||

3000 | E2fsprogs 1.40.5 (January 27, 2008) |
3001 | =================================== | |
3002 | ||
3003 | Fix a potential overflow big in e2image if the device name is too | |
3004 | long. | |
3005 | ||
3006 | Mke2fs will now create new filesystems with 256 byte inodes and the | |
3007 | ext_attr feature flag by default. This allows for much better future | |
3008 | compatibity with ext4 and speeds up extended attributes even on ext3 | |
3009 | filesystems. | |
3010 | ||
3011 | Teach e2fsck to ignore certain "safe" filesystem features which are | |
3012 | set automatically by the kernel. Having the kernel set features | |
3013 | automagically behind the user's back is a bad idea, and we should try | |
3014 | to break the kernel of this habit, especially for the newer ext4 | |
3015 | feature flags. But for now, we will try to avoid needless full checks | |
3016 | which can annoy users who are doing fresh installs. | |
3017 | ||
3018 | Add support in tune2fs and mke2fs for making a filesystem as being "ok | |
3019 | to be used with test kernel code". This will be needed for using test | |
3020 | filesystems with the latest ext4 kernel code. | |
3021 | ||
3022 | Change e2fsck -fD so that it sorts non-htree directories by inode | |
3023 | numbers instead of by name, since that optimizes performances much | |
3024 | more significantly. (Addresses-Sourceforge-Feature-Request: #532439) | |
3025 | ||
3026 | If e2image fills the disk, fix it so it exits right away instead of | |
3027 | spewing large numbers of error messages. | |
3028 | (Addresses-Sourceforge-Feature-Request: #606508) | |
3029 | ||
3030 | If ftruncate64() is not available for resize2fs, let it use ftrucate() | |
3031 | instead, but have it check to see if the size would get truncated, and | |
3032 | skip calling ftruncate in that case. | |
3033 | ||
3034 | Add support for detecting HFS+ filesystems in the blkid library. | |
3035 | ||
3036 | Add supprt in the blkid library for ext4/ext4dev filesystems. | |
3037 | ||
3038 | Fix a bug in blkid where it could die on a floating point exception | |
3039 | when presented with a corrupt reiserfs image. | |
3040 | ||
3041 | Fix blkid's handling of ntfs UUID's so that leading zeros are printed | |
3042 | such that UUID string is a fixed length. | |
3043 | ||
3044 | Add sample python bindings for the uuid library to the contrib | |
3045 | directory. (Addresses-Sourceforge-Patches: #778817) | |
3046 | ||
3047 | Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it | |
3048 | will work with large files. (Addresses Sourceforge Feature Request: | |
3049 | #1257500 and Sourceforge Support Request: #1253511) | |
3050 | ||
3051 | Allow the debugfs 'undel' command to undelete an inode without linking | |
3052 | it to a specific destination directory, since this might require | |
3053 | allocating blocks that could overwrite some yet-to-be-recovered | |
3054 | deleted files. (Addresses-Sourceforge-Feature-Request: #967141) | |
3055 | ||
3056 | Update Swedish translations from the Translation Project. | |
3057 | ||
3058 | Programmer's Notes: | |
3059 | ------------------- | |
3060 | ||
3061 | Fix configure handling of --sbindir (which should rarely be used, but | |
3062 | someone did complain, so let's fix it). (Addresses Sourceforge Bug: | |
3063 | #498381) | |
3064 | ||
3065 | Updated e2fsprogs.spec file to include a new uuidd package | |
3066 | ||
3067 | Use pkg-config to determine where to find the devmapper library so we | |
3068 | can find out where it is located on different distributions. | |
3069 | ||
3070 | Fix Makefile race so that "make -j3 distclean" works correctly | |
3071 | ||
3072 | Fix portability problems on non-Linux/non-Hurd/non-Masix systems, | |
3073 | especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633, | |
3074 | #1819034, #1863819) | |
3075 | ||
3076 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
3077 | ||
3078 | Fixed various Debian packaging issues --- see debian/changelog for | |
3079 | details. (Addresses Debian Bugs: #459403, #459475, #459614) | |
3080 | ||
3081 | Remove the --enable-dynamic-static configure option, and build e2fsck | |
3082 | dynamically by default. If the user wants e2fsck.static, he/she will | |
3083 | need to build it via "make -C e2fsck e2fsck.static" | |
3084 | ||
3085 | Fix various build warnings due to missing prototypes. | |

3089 | E2fsprogs 1.40.4 (December 31, 2007) |
3090 | ==================================== | |
3091 | ||
3092 | Improve time-based UUID generation. A new daemon uuidd, is started | |
3093 | automatically by libuuid if necessary. This daemon is setuid to allow | |
3094 | updates to /var/lib/libuuid, so the clock sequence number can be | |
3095 | stored and so if the clock is set backwards, it can be detected. | |
3096 | (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla: | |
3097 | #233471) | |
3098 | ||
3099 | Filter out the NEEDS_RECOVERY feature flag when writing out the backup | |
3100 | superblocks. This avoids e2fsck from concluding that a full | |
3101 | filesystem check is required before backing up the superblock due to | |
3102 | changes in the feature flags. (Addresses Debian Bug: #454926) | |
3103 | ||
3104 | Fix fsck to only treat the '#' character as a comment at the beginning | |
3105 | of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem | |
3106 | will cause fsck to issue an bogus warning message. | |
3107 | (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147) | |
3108 | ||
3109 | Format control characters and characters with the high eighth bit set | |
3110 | when printing the contents of the blkid cache, to prevent filesystems | |
3111 | with garbage labels from sending escape sequences to the user's screen | |
3112 | that might, for example place it in graphics mode. (Addresses Ubuntu | |
3113 | Bug: #78087) | |
3114 | ||
3115 | Fix sign-extension problem on 64-bit systems in in the com_err | |
3116 | library. (Addresses Sourceforge Bug: #1809658) | |
3117 | ||
3118 | Avoid division by zero error when probing an invalid FAT filesystem in | |
3119 | the blkid library. (Addresses Sourceforge Bug: #1831627) | |
3120 | ||
3121 | Update Dutch, Polish, and Vietnamese translations from the Translation | |
3122 | Project. Remove the Rwandan translation upon advice of the | |
3123 | Translation Project. | |
3124 | ||
3125 | Programmer's Notes: | |
3126 | ------------------- | |
3127 | ||
3128 | Fix the libss "make check" regression test so that it works if the | |
3129 | current directory is not in the user's path or if the libss shared | |
3130 | library is not installed. (Addresses Sourceforge Bug: #1848974) | |
3131 | ||
3132 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
3133 | (Addresses Debian Bugs: #444883, #441872) | |
3134 | ||
3135 | Fixed various Debian packaging issues --- see debian/changelog for | |
3136 | details. (Addresses Debian Bugs: #437720, #451172, #458017) | |
3137 | ||
3138 | Fix build failure on non-Linux/non-Hurd/non-Masix systems. | |
3139 | (Addresses Sourceforge Bug: #1859778) | |
3140 | ||
3141 | Fix Hurd portability issues. (Addresses Debian Bug: #437720) | |

3144 | E2fsprogs 1.40.3 (December 5, 2007) |
3145 | =================================== | |
3146 | ||
3147 | Fix a potential security vulnerability where an untrusted filesystem | |
3148 | can be corrupted in such a way that a program using libext2fs will | |
3149 | allocate a buffer which is far too small. This can lead to either a | |
3150 | crash or potentially a heap-based buffer overflow crash. No known | |
3151 | exploits exist, but main concern is where an untrusted user who | |
3152 | possesses privileged access in a guest Xen environment could corrupt a | |
3153 | filesystem which is then accessed by the pygrub program, running as | |
3154 | root in the dom0 host environment, thus allowing the untrusted user to | |
3155 | gain privileged access in the host OS. Thanks to the McAfee AVERT | |
3156 | Research group for reporting this issue. (Addresses CVE-2007-5497.) | |
3157 | ||
3158 | Fix hueristics in blkid which could cause a disk without partitions to | |
3159 | be incorrectly skipped when a loopback device is present. (Addresses | |
3160 | Red Hat Bugzilla #400321.) | |
3161 | ||
3162 | Fix e2image so that in raw mode it does not create an image file which | |
3163 | is one byte too large. | |
3164 | ||
3165 | Change mke2fs's usage message so it recommends the preferred -E option | |
3166 | instead of the deprecated -R option. | |
3167 | ||
3168 | Enhance the blkid library so it will recognize squashfs filesystems. | |
3169 | (Addresses Red Hat Bugzilla #305151.) | |
3170 | ||
3171 | Enhance e2fsck so it will force the backup superblocks to be backed up | |
3172 | if the filesystem is consistent and key constants have been changed | |
3173 | (i.e., by an on-line resize) or by e2fsck in the course of its | |
3174 | operations. | |
3175 | ||
3176 | Enhance blkid's detection of FAT filesystems; so that USB disks with | |
3177 | only a single bootable partition will not get missed. | |
3178 | ||
3179 | E2fsck will no longer mark a filesystem as invalid if it has time | |
3180 | errors (i.e., if superblock mount time or last write time is in the | |
3181 | future) and the user refuses to fix the problem. | |
3182 | ||
3183 | The Ubuntu init scripts don't properly set the system time correctly | |
3184 | from hardware clock if the hardware clock is configured to tick local | |
3185 | time instead of GMT time. Work around this as best as we can by | |
3186 | providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can | |
3187 | be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu | |
3188 | Bug #131201.) | |
3189 | ||
3190 | Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red | |
3191 | Hat Bugzilla #151533.) | |
3192 | ||
3193 | Fix e2fsck so that if the superblock is corrupt, but still looks | |
3194 | vaguely like an ext2/3/4 superblock, that it automatically tries to | |
3195 | fall back to the backup superblock, instead of failing with a hard | |
3196 | error. | |
3197 | ||
3198 | Make the e2fsprogs program more robust so that they will not crash | |
3199 | when opening a corrupt filesystem where s_inode_size is zero. | |
3200 | ||
3201 | Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric | |
3202 | arguments are detected as such and the parse error is reported to the | |
3203 | user. (Addresses Debian Bug #435381.) | |
3204 | ||
3205 | Change e2fsck so it will not complain if a file has blocks reallocated | |
3206 | up to the next multiple of a system's page size. | |
3207 | ||
3208 | Fix bug in ext2fs_check_desc() which will cause e2fsck to complain | |
3209 | about (valid) filesystems where the inode table extends to the last | |
3210 | block of the block group. (Addresses Red Hat Bugzilla #214765.) | |
3211 | ||
3212 | Fix a bug in ext2fs_initialize() which causes mke2fs to fail while | |
3213 | allocating inode tables for some relatively rare odd disk sizes. | |
3214 | (Addresses Red Hat Bugzilla #241767.) | |
3215 | ||
3216 | Add Catalan translation and update Dutch and Swedish translations | |
3217 | from the Translation Project. | |
3218 | ||
3219 | Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We | |
3220 | still had an issue when trying to figure out whether we need to | |
3221 | byte-swap fast symlinks that contained extended attributes. | |
3222 | ||
3223 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
3224 | (Addresses SourceForge Bug #1821333.) | |
3225 | ||
3226 | ||
3227 | Programmer's Notes: | |
3228 | ------------------- | |
3229 | ||
3230 | Fix mke2fs tests to avoid needing any significant ^M (CR) characters | |
3231 | ||
3232 | Add "make check" to the RPM spec file | |
3233 | ||
3234 | Fix "make install" and 'make unstall" in misc/Makefile.in so that it | |
3235 | works correctly when the prefix is not the root directory. | |
3236 | ||
3237 | Fix the resize2fs tests, r_move_itable and r_resize_inode, so they | |
3238 | clena up after themselves by deleting the test.img temporary file | |
3239 | after completing the test. | |
3240 | ||
3241 | Fixed a corner case bug ext2fs_unlink() when trying to delete the | |
3242 | first directory entry in a directory block and the last directory | |
3243 | entry in the previous directory block is not in use. Fortunately | |
3244 | ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in | |
3245 | places where it is extremely unlikely to run into this corner case. | |
3246 | ||
3247 | Fix missing dependency which would cuase parallel builds to fail. | |
3248 | (Addresses Sourceforge Bug #1842331.) | |

3260 | E2fsprogs 1.40.2 (July 12, 2007) |
3261 | ================================ | |
3262 | ||
3263 | A recent change to e2fsck_add_dir_info() to use tdb files to check | |
3264 | filesystems with a very large number of filesystems had a typo which | |
3265 | caused us to resize the wrong data structure. This would cause a | |
3266 | array overrun leading to malloc pointer corruptions and segfaults. | |
3267 | Since we normally can very accurately predict how big the the dirinfo | |
3268 | array needs to be, this bug only got triggered on very badly corrupted | |
3269 | filesystems. | |
3270 | ||
3271 | Fix a bug in e2fsck which caused it to incorrectly salvange | |
3272 | directories when the last entry's rec_len is bogusly too big. This | |
3273 | resulted in a nonsense filesystem corruption to be reported, and | |
3274 | required a second run of e2fsck to fully fix up the directory. | |
3275 | ||
3276 | Update tune2fs man page to include more discussion of reserved blocks | |
3277 | (Addresses Launchpad bug #47817) | |

3285 | |
3286 | Fix bug which could cause libblkid to loop forever. When revalidating | |
3287 | a partition where there is obsolete information in /etc/blkid.tab, we | |
3288 | end up freeing a the type tag without clearing dev->bid_type, causing | |
3289 | blkid_verify() to loop forever. (Addresses Debian Bug: #432052) | |
3290 | ||
3291 | The Turkish translation has a bug in it where it has the translation | |
3292 | of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at | |
3293 | @E, recursively, forever, until the stack fills up and e2fsck core | |
3294 | dumps. We fix this by making e2fsck stop @-expansions after a | |
3295 | recursive depth of 10, which is far more than we need. | |

3297 | |
3298 | Compile the default mke2fs.conf into mke2fs program. People are | |
3299 | getting surprised by mke2fs creating filesystems with different | |
3300 | defaults than earlier versions of mke2fs if mke2fs.conf is not | |
3301 | present. So we now create a built in version of mke2fs.conf file | |
3302 | which is used by mke2fs if the /etc/mke2fs.conf is not present. | |
3303 | (Addresses SourceforgeBug: #1745818) | |
3304 | ||
3305 | Improve the config/parse_types.sh helper script. Fix a potential | |
3306 | security problem if e2fsprogs is built as root (as Gentoo does!). In | |
3307 | addition fix the script and how it is called from the configure script | |
3308 | so that it does the right thing when cross-compiling. (Fixes Gentoo | |
3309 | bug: #146903) | |
3310 | ||
3311 | Update Vietnamese, French, and Dutch PO files from the Translation | |
3312 | Project. Also created a new e2fsprogs.pot file for translator. | |
3313 | ||
3314 | Fix bogus strip permission errors when building under Debian. When | |
3315 | building the e2fsprogs dpkg's, the dh_strip command emits a large | |
3316 | number of error messages caused by the permissions not being right. | |
3317 | So run dh_fixperms before running dh_strip. | |

3318 | |
3319 | Programmer's Notes: | |
3320 | ------------------- | |
3321 | ||
3322 | Add new function: profile_set_default(). This function sets the value | |
3323 | of the pseudo file "<default>". If the file "<default>" had | |
3324 | previously been passed to profile_init(), then def_string parameter | |
3325 | will be parsed and used as the profile information for the "<default>" | |
3326 | file. | |
3327 | ||
3328 | Fix mk_cmds's error reporting so that it is unambiguous that it is the | |
3329 | mk_cmds script which is generating the error. (Obviates Gentoo patch: | |
3330 | e2fsprogs-1.32-mk_cmds-cosmetic.patch) | |
3331 | ||
3332 | Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high | |
3333 | priority" environment variable that overrides all others, where as | |
3334 | LANG is the lowest priorty environment variable. If LC_ALL is set, it | |
3335 | doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and | |
3336 | the all the rest are set. This will assure that the locale when | |
3337 | running the test suites is the "C" locale. (Obviates Gentoo patch: | |
3338 | e2fsprogs-1.38-tests-locale.patch) | |

3343 | ||
3344 | Fix divide by zero error in blkid's NTFS probing logic. | |
d7b64725 TT |
3345 | |
3346 | Add new blkid -g option which causes the blkid cache to be garbage | |
3347 | collected. | |
3348 | ||
3349 | Fix a bug in libblkid which could cause the internal field bid_type to | |
3350 | become corrupted. Fortunately bid_type isn't used much, and bid_label | |
3351 | and bid_uuid is only used by debugging code, so the impact of this bug | |
3352 | was very minor. | |
3353 | ||
3354 | Mke2fs will now store the RAID stride value when a filesystem is | |
3355 | created with a requested RAID stride, and then use it automatically in | |
3356 | resize2fs. | |
3357 | ||
3358 | Mke2fs has a sanity check added to make sure (inode_size * num_inodes) | |
3359 | isn't too big. In some cases Lustre users have tried specifying an | |
3360 | inode size of 4096 bytes, while keeping an inode ratio of one inode | |
3361 | per 4096 bytes. | |
3362 | ||
3363 | Improve sanity check in e2fsck's algorithm for finding a backup | |
3364 | superblock, so that it won't accidentally find a superblock that was | |
3365 | located in the journal, and then later reject it as being not a valid | |
3366 | backup superblock. | |
3367 | ||
3368 | Fix e2fsck get_size logic so that it will work with the Linux floppy | |
3369 | driver. The Linux floppy driver is a bit different from the other | |
3370 | block device drivers, in that if the device has been opened with | |
3371 | O_EXCL, it disallows another open(), even if the second open() does | |
3372 | not have the O_EXCL flag. (Addresses Debian Bug: #410569) | |
3373 | ||
3374 | Fix error checking of badblock's last-block and start-block arguments. | |
3375 | (Addresses Debian Bug: #416477) | |
3376 | ||
3377 | Fix e2fsck so that it doesn't overwrite the backup superblocks when | |
3378 | recovering a journal until the master superblock has been confirmed as | |
3379 | being sane. | |
3380 | ||
3381 | Change the blkid library to be much more paranoid about concluding | |
3382 | that a partition contains an NTFS filesystem, and fetch the UUID and | |
3383 | LABEL information from NTFS filesystems. (Addresses Launchpad Bug: | |
3384 | #110138) | |
3385 | ||
3386 | Factor out the code which sets the default journal size and move it | |
3387 | into libext2fs. | |
3388 | ||
3389 | Enhance e2fsck so it will recreate the ext3 journal if the original | |
3390 | journal inode was cleared to due it being corrupt after finishing the | |
3391 | filesystem check. | |
3392 | ||
3393 | Fix e2fsck so that it updates the journal inode if it is corrupted and | |
3394 | the backup journal information from the superblock was successfully | |
3395 | used to recover the filesystem. | |
3396 | ||
3397 | Fix e2fsck so that it checks all of the blocks in the journal inode | |
3398 | for validity. The original code only checked the direct blocks to | |
3399 | make sure the journal inode was sane. Unfortunately, if some or all | |
3400 | of the indirect or doubly indirect blocks were corrupted, this would | |
3401 | not be caught. | |
3402 | ||
3403 | Add support in blkid to detect LUKS encrypted partitions. | |
3404 | ||
3405 | Add extra sanity checks for extended attributes in the case where the | |
3406 | size is zero but the offset is very large. | |
3407 | ||
3408 | Fix byte-swapping issues for large inodes in ext2fs_read_inode_full() | |
3409 | and ext2fs_get_next_inode_full(). | |
3410 | ||
3411 | Clarify the copyright licenses used by the various libraries in | |
3412 | the top-level COPYING file (Red Hat Bugzilla: 166058) | |
3413 | ||
3414 | Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane. | |
3415 | ||
3416 | Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's. | |
3417 | ||
3418 | Remove check in e2fsck which requires EA's in inodes to be sorted; | |
3419 | they don't need to be sorted, and e2fsck was previously wrongly | |
3420 | clearing unsorted EA's stored in the inode structure. | |
3421 | ||
3422 | Allow mke2fs or tune2fs to create a substantially larger journal (up | |
3423 | to 10,240,000 blocks). | |
3424 | ||
3425 | Fix MD superblock detection, and make sure the correct UUID is | |
3426 | reported from the MD superblock. | |
3427 | ||
3428 | Fix a signed vs. unsigned bug in debugfs. | |
3429 | ||
3430 | Enhance debugfs's date parser so that it accepts integer values. | |
3431 | ||
3432 | Fix e2fsck's pass1c accounting so it doesn't terminate too early if a | |
3433 | file with multiply claimed blocks is hard linked. or not at all if the | |
3434 | root directory contains shared blocks | |
3435 | ||
3436 | Enhance debugfs so it can modify the block group descriptors using the | |
3437 | command set_block_group_descriptor. | |
3438 | ||
3439 | Improve e2fsck's reporting of I/O errors so it's clearer what it was | |
3440 | trying to do when an error happens | |
3441 | ||
3442 | Fix a bug in in how e2fsprogs byte swaps inodes containing fast | |
3443 | symlinks that have extended attributes. (Addresses Red Hat Bugzilla: | |
3444 | #232663 and LTC Bugzilla: #27634) | |

3447 | error case. | |

3451 | Impove badblocks -n/-w exclusive usage message. | |
3452 | ||
3453 | Fix dump_unused segfault in debugfs when a filesystem is not open | |
3454 | ||
3455 | Fix memory leak in blkid library. (Addresses Debian Bug: #413661) | |
3456 | ||
3457 | Allow the debugfs lcd command to work w/o a filesystem being open. | |
3458 | (Addresses LTC Bugzilla #27513) | |
3459 | ||
3460 | Fix e2fsck to clear i_size for special devices with a bogus i_blocks | |
3461 | field on the first pass. | |
3462 | ||
3463 | Fix e2fsck to set the file type of the '..' entry when connecting | |
3464 | a directory to lost+found. (Addresses Lustre Bug: #11645) | |
3465 | ||
3466 | Enhance e2fsck to recover directories whose modes field were corrupted | |
3467 | to look like special files. This is probably only useful in | |
3468 | artificial test cases, but it will be useful if we ever do the "inodes | |
3469 | in directory" idea for ext4. | |
3470 | ||
3471 | Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug: | |
3472 | #412614) | |
3473 | ||
3474 | Fix resize2fs parsing of size parameter (in sector units). This was | |
3475 | actually a bug in libe2p's parse_num_blocks() function. When handling | |
3476 | the 's' suffix, it was ignoring the blocksize information passed in | |
3477 | from the caller and always interpreting the number in terms of a 1k | |
3478 | blocksize. (Addresses Debian Bug: #408298) | |
3479 | ||
3480 | There was a floating point precision error which could cause e2fsck to | |
3481 | loop forever on really big filesystems with a large inode count. | |
3482 | (Addresses Debian Bug: #411838) | |
3483 | ||
3484 | Fix memory leak in ext2fs_write_new_inode() | |
3485 | ||
3486 | Add support for using a scratch files directory to reduce e2fsck's | |
499d5ec5 | 3487 | memory utilization on really big filesystems. This uses the TDB |
a0d42548 TT |
3488 | library. See the [scratch_files] section of the e2fsck.conf man page |

3496 | ||
3497 | Allow debugfs and dumpe2fs to support fs features under development. | |
3498 | ||
3499 | Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to | |
3500 | ext2fs_open() , which allows application to open filesystes with features | |
3501 | which are currently only partially supported by e2fsprogs. | |

3505 | |
3506 | Fixed overflow and signed/unsigned problems caused by the number of | |
7809bc56 TT |
3507 | blocks or inodes exceeding 2**31 or being close to 2**32-1. |
3508 | ||
3509 | Add support for unsigned directory hash calculations with hints in the | |
3510 | superblock to fix cross-architectural portability for htree | |
3511 | directories with filenames where the high 8th bit is set. (Addresses | |
3512 | Debian: #389772) | |
26bcc2ca TT |
3513 | |
3514 | Fix resize2fs so that it gives user-intelligible error messages if the | |
3515 | filesystem or the kernel does not support on-line resizing. | |
3516 | (Addresses Debian Bug: #380548) | |
3517 | ||
3518 | Require mke2fs -F -F for really dangerous operations, since -F is | |
3519 | needed for less dangerous operations such as creating filesystems | |
3520 | images in regular files, or creating filesystems on whole block | |
3521 | devices. These relatively innocuous usages should NOT be confused | |
3522 | with running mke2fs on an apparently-mounted or in-use filesystem. | |
3523 | ||
3524 | Allow the default inode size to be specified into the mke2fs.conf | |
3525 | file. | |
3526 | ||
3527 | Make the smallest default journal size is big enough so that on-line | |
3528 | resizing should always work. | |

3539 | Add support in lsattr so it will display the EXT4_EXTENTS_FL flag. | |
3540 | ||
3541 | Device mapper scanning wasn't working in the blkid library because the | |
3542 | pathnames had an extra "/dev" when they were being probed. | |
3543 | ||
3544 | Add GFS/GFS2 support to the blkid library. | |
3545 | ||
3546 | Fix blkid support of empty FAT filesystem labels. | |
3547 | ||
3548 | Avoid recursing forever (or for a long time) when the blkid library | |
3549 | searches for a device and there are symlinks to directories in /dev. | |
3550 | ||
3551 | Avoid unaligned halfword access in blkid when accessing FAT | |
3552 | superblocks, as this will cause Sparc/Solaris systems to throw a | |
3553 | SIGBUS error. | |

3576 | don't have do the dfsg tarball. Also remove the rule that only tried | |

a0d42548 TT |
3597 | E2fsck now supports the %It expansion when printing a problem report. |
3598 | It will print the type of the inode in the problem context. | |
3599 | ||
26bcc2ca TT |
3600 | Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet |
3601 | (Addresses Sourceforge Bug: #1565561) | |
3602 | ||
3603 | Remove unused variables and other lint/gcc -Wall cleanups | |
3604 | ||
3605 | Add check to ext2fs_get_device_size() so it will return EFBIG for for | |
3606 | filesystems contained in regular files where the filesystem image size | |
3607 | is returned by stat64(). | |
3608 | ||
7809bc56 TT |
3609 | Set local environment variables to C so mk_cmds and compile_et always |
3610 | work. (Addresses SourceForge Bug: #1532177) | |
3611 | ||
26bcc2ca TT |
3612 | Added the 64-bit byte swapping function ext2fs_swab64(). |
3613 | ||
3614 | Added two new helper functions to prevent 2**31/2**32-1 overflow | |
3615 | problems: ext2fs_div_ceil() and e2p_percent(). | |
3616 | ||
3617 | Create new ext2fs library inline functions ext2fs_group_first_block() | |
3618 | and ext2fs_group_last_block() in order to calculate the starting and | |
3619 | ending blocks in a block group. | |
3620 | ||
3621 | Create the generated files read-only to remind developers not to edit them. | |
3622 | ||
7809bc56 TT |
3623 | Add support for autoconf 2.60 (with backwards compatibility for older |
3624 | versions of autoconf). | |
3625 | ||
26bcc2ca TT |
3626 | Added an "make rpm" target to top-level Makefile |
3627 | ||
3628 | Added various FreeBSD portability fixes. | |
3629 | ||
3630 | Exclude mercurial files from the RPM build tree to speed up copy/build. | |
3631 | ||
3632 | Use root_sysconfdir to define the locations of mke2fs.conf and | |
3633 | e2fsck.conf instead of using a hard-coded /etc pathname. | |
3634 | ||
3635 | Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times. | |
3636 | ||
3637 | Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files. | |

3645 | EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT, | |
3646 | EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE | |
3647 | ||
3648 | Add a new make target "checked-failed" in the tests directory which | |
3649 | reruns any failed tests | |
3650 | ||
3651 | Update draft-leach-uuids-guids-01.txt with rfc4122.txt | |
3652 | ||
a0d42548 TT |
3653 | Fix miscellaneous bugs reported by Coverity: Dead code, potential nul |
3654 | pointer dereferences, memory leaks, etc. None were security-criticial | |
3655 | problems. | |
3656 | ||
3657 | Fix up usage and decrement error messages in the test_icount program | |
3658 | ||
3659 | Add debugging code to the com_err library; if the environment variable | |
3660 | COMERR_DEBUG is set to 1, print out debugging messages as error tables | |
3661 | are added and removed from the com_err library. If the | |
3662 | COMERR_DEBUG_FILE environment variable is set (and the process is not | |
3663 | setuid) the debugging messages may be redirected to a file. | |
3664 | ||
3665 | Change all of the e2fsprogs programs to use the newer add_error_table() | |
3666 | and remove_error_table() interfaces instead of the much older | |
3667 | initialize_*_error_table() function. | |
3668 | ||
3669 | Add TDB support into the ext2fs library. This allows us to have a | |
3670 | guaranteed library we can count on always being present so we can | |
3671 | store data in an on-disk database. | |
3672 | ||
3673 | Add support for using TDB to store the icount data, so we don't run out | |
3674 | of memory when checking really large filesystems. | |
3675 | ||
d7b64725 TT |
3676 | Change the regression test suite so that it skips empty test directories. |
3677 | ||
3678 | Define the l_i_iversion field in ext2_inode. The l_i_version field is | |
3679 | now defined from the old l_i_reserved1 field in the ext2 inode. This | |
3680 | field will be used to store high 32 bits of the 64-bit inode version | |
3681 | number. | |
3682 | ||
3683 | Add Makefile production rule for e2fsprogs.spec in case it gets | |
3684 | deleted. | |
3685 | ||
3686 | Add new function profile_get_uint() to allow for a clean way to fetch | |
3687 | unsigned integers from the context. | |
3688 | ||
3689 | Add test to make sure the ext2 superblock structure is 1024 bytes. | |
3690 | ||
3691 | Fix typo in name of f_dup4 regression test | |
3692 | ||
3693 | Add new function blkid_gc_cache() which performs a garbage collection | |
3694 | pass on the /etc/blkid.tab file. | |
3695 | ||
3696 | The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In | |
3697 | general, only e2fsck (after the filesystem is clean), tune2fs, and | |
3698 | resize2fs should change the backup superblocks by default. Most | |
3699 | callers of ext2fs_open() should not be touching any superblock fields | |
3700 | which require the backups to be touched. | |
3701 | ||
3702 | Add new function to libext2fs, ext2fs_default_journal_size(), which | |
3703 | returns the default journal size. | |
3704 | ||

3706 | E2fsprogs 1.39 (May 29, 2006) |
3707 | ============================= | |
34a2611c | 3708 | |
34a2611c TT |
3709 | Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems |
3710 | between 2**31 and 2**32 blocks. | |
3711 | ||
34a2611c TT |
3712 | Change mke2fs to use /etc/mke2fs.conf as a configuration file to |
3713 | configure the filesystem features, blocksize, and inode_ratio for | |
3714 | different filesystem types. | |
3715 | ||
6c09475b TT |
3716 | Mke2fs will now create filesystems hash trees and on-line resizing |
3717 | enabled by default, based on the new /etc/mke2fs.conf file. | |
3718 | ||
34a2611c TT |
3719 | The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the |
3720 | filesystem device node in exclusive mode to prevent accidents by | |
3721 | system administrators. In the case of resize2fs and mke2fs, it will | |
3722 | only use exclusive mode if the filesystem is not mounted. | |
3723 | ||
3724 | Fixed a bug in mke2fs which caused it to to fail when creating the | |
3725 | resize inode for large filesystems. (Addresses Debian Bug #346580) | |
3726 | ||
bae55640 TT |
3727 | When allocating space for the RAID filesystems with the stride |
3728 | parameter, mke2fs will now place each portion of the group's inode | |
3729 | table right up after the superblock (if present) in order to minimize | |
3730 | fragmentation of the freespace. | |
3731 | ||
3732 | Speed up mke2fs and e2fsck by writing inode and block bitmaps more | |
3733 | efficiently by writing the inode and block bitmaps in one pass, thus | |
3734 | reducing the number of disk seeks required. | |
3735 | ||
34a2611c TT |
3736 | Add support for on-line resizing to resize2fs. |
3737 | ||
3738 | Fix blkid library so that logic to determine whether or not a device's | |
3739 | cached information in /etc/blkid.tab needs to be verified or not | |
3740 | doesn't get confused by a system clock which is insane (for example, | |
3741 | if the battery is dead on a Macintosh running PPC Linux. (Addresses | |
3742 | Red Hat Bug: #182188) | |
3743 | ||
3744 | The blkid library will now store the UUID of the external journal used | |
3745 | by ext3 filesystems, so that in the future, the userspace mount binary | |
3746 | can use this to find the location of the external journal and pass | |
3747 | this information to the kernel. | |
f3227850 TT |
3748 | |
3749 | E2fsck will now consult a configuration file, /etc/e2fsck.conf to | |
34a2611c TT |
3750 | control how various options should be handled. See the e2fsck.conf |
3751 | man page for more details. (Addresses Debian Bug: #150295) | |
f3227850 | 3752 | |
34a2611c TT |
3753 | E2fsck now prints an explanatory message when delaying a filesystem |
3754 | check when the system is running on battery. (Addresses Debian Bug: | |
3755 | #350306) | |
f2b74cda | 3756 | |
4c02c41c TT |
3757 | E2fsck will detect if the superblock's last mount field or last write |
3758 | field is in the future, and offer to fix if so. (Addresses Debian Bug | |
f3227850 TT |
3759 | #327580) These problems will be fixed automatically in preen mode |
3760 | since Debian's boot sequence bogusly doesn't set the time correctly | |
3761 | until potentially very late in the bootup process, and this can cause | |
3762 | false positives which will cause users' systems to fail to boot. | |
3763 | (Addresses Debian Bugs #343662 and #343645) | |
f2b74cda | 3764 | |
34a2611c TT |
3765 | E2fsck now checks to see if the superblock hint for the location of |
3766 | the external journal is incorrect, and if so, offer to update it. | |
3767 | (Addresses Debian Bug: #355644) | |
3768 | ||
f2b74cda TT |
3769 | Fix e2fsck from segfaulting on disconnected inodes that contain one or |
3770 | more extended attributes. (Addresses Debian Bug: #316736, #318463) | |
3771 | ||
4c02c41c TT |
3772 | E2fsck will stop and print a warning if the user tries running a |
3773 | read/write badblocks test on a read-only mounted root filesystem. | |
3774 | ||
bae55640 TT |
3775 | Fix a memory leak in e2fsck's error paths. (Thanks to Michael |
3776 | C. Thompson for pointing these out; they were originally found using | |
3777 | Coverity.) | |
3778 | ||
f3227850 TT |
3779 | When resizing a file containing a filesystem, resize2fs will expand or |
3780 | truncate a file as necessary. (Addresses Debian Bug: #271607) | |
3781 | ||
bae55640 TT |
3782 | Resize2fs will now automatically determine the RAID stride parameter that |
3783 | had been used to create the filesystem, and use that for newly created | |
3784 | block groups. The RAID stride parameter may also be manually specified | |
3785 | on the command line using the new -S option to resize2fs. | |
3786 | ||
4c02c41c TT |
3787 | Fix mke2fs so that it correctly creates external journals on |
3788 | big-endian machines (such as a S/390). | |
3789 | ||
bae55640 TT |
3790 | Fix a bug in the e2p library which could cause dumpe2fs to (rarely) |
3791 | fail to print out the journal or hash seed UUID. (Thanks to Guillaume | |
3792 | Chambraud for pointing this out.) | |
3793 | ||
3794 | Dumpe2fs will now print the size of the journal (if present). | |
3795 | ||
4c02c41c TT |
3796 | Fix debugfs's set_inode_field command so it can properly set the frag, |
3797 | fsize, uid_high, gid_high, and author fields in the inode instead of | |
3798 | silently failing, and so that setting the i_size actually sets i_size | |
3799 | correctly. | |
3800 | ||
3801 | Add a new debugfs command, set_current_time, which sets fs->now so | |
3802 | that regression test suites can repeatedly modify the filesystem's | |
3803 | last_write fields. | |
3804 | ||
34a2611c TT |
3805 | Fix a bug in debugfs's icheck which would incorrectly report the owner |
3806 | of an extended attribute block. | |
3807 | ||
bae55640 TT |
3808 | Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a |
3809 | print a usage message when an illegal option character is given. | |
3810 | ||
6c09475b TT |
3811 | Fix debugfs's dump_unsued command on filesystems with a 64k blocksize |
3812 | so it won't core dump. (Addresses SourceForge bug #1424311) | |
3813 | ||
bae55640 TT |
3814 | Fix mklost+found so that it creates a full-sized directory on |
3815 | filesystems with larger block sizes. | |
3816 | ||
3817 | Fix a file descriptor leak in blkid library. | |
3818 | ||
4c02c41c TT |
3819 | Fix a display bug in "badblocks -sv" so that the done message properly |
3820 | clears the block number at the end of the test. (Addresses Debian Bug | |
3821 | #322231) | |
3822 | ||
f2b74cda TT |
3823 | Allow fractional percentages to the -m option in mke2fs and tune2fs |
3824 | (Addresses Debian Bug: #80205) | |
3825 | ||
3826 | Use fstat/fstat64 in getsize.c if the the target is a regular file, | |
3827 | instead of attempting to do a binary search. Fix some fd leaks in | |
3828 | error cases. | |
3829 | ||
34a2611c TT |
3830 | Add support for device mapper library to the blkid library to ensure |
3831 | that the "best" (i.e., leaf) device is probed by the blkid library. | |
3832 | ||
4c02c41c TT |
3833 | Fix the blkid library so that it notices when an ext2 filesystem is |
3834 | upgraded to ext3. | |
3835 | ||
3836 | Improve the blkid's library VFAT/FAT detection; it now understands | |
3837 | labels stored in the root directory, and is more paranoid about | |
3838 | checking the FAT superblock values. | |
3839 | ||
34a2611c TT |
3840 | Fixed a fd leak in the uuid library which was causing problems for the |
3841 | LVM tools. (Addresses Debian Bug: #345832) | |
3842 | ||
4c02c41c TT |
3843 | Add support for the reiser4 and software suspend partitions to the |
3844 | blkid library. Also add support for extract the label from iso9660 | |
3845 | filesystems. | |
3846 | ||
f2b74cda TT |
3847 | Fix a compile_et bug which miscount the number of error messages if |
3848 | continuations are used in the .et file. | |
3849 | ||
3850 | Add extra sanity checks to protect users from unusual cirucmstances | |
3851 | where /etc/mtab may not be sane, by checking to see if the device is | |
3852 | reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug | |
3853 | #319002) | |
3854 | ||
34a2611c TT |
3855 | Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian |
3856 | Bug: #343149, #341911, #300871, #316604, #316782, #330789) | |
4c02c41c | 3857 | |
f2b74cda TT |
3858 | Fix use-after-free bug in e2fsck when finishing up the use of the |
3859 | e2fsck context structure. | |
3860 | ||
34a2611c TT |
3861 | Fixed spelling mistakes, typos, and otherwise clarified man pages and |
3862 | documentation. (Addresses Debian Bugs: #329859, #322188, #316811, | |

3872 | Programmer's notes: | |
3873 | ------------------- | |
3874 | ||
7e2ec011 TT |
3875 | Update config.guess and config.sub to latest version (2006-02-23) from |
3876 | FSF. | |
3877 | ||
3878 | Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian | |
3879 | Bugs: #360661, #360317) | |
3880 | ||
34a2611c TT |
3881 | Fixed the Makefile so that they work correctly on newer versions of |
3882 | GNU make (i.e., 3.81). | |
3883 | ||
f2b74cda TT |
3884 | Add valgrind support to the regression test suites, and eliminate |
3885 | false positives from valgrind. | |
3886 | ||
4c02c41c TT |
3887 | Add a regression test suite for the blkid library. |
3888 | ||
f2b74cda TT |
3889 | Fix a fencepost error in resize2fs caught by valgrind. |
3890 | ||
4c02c41c TT |
3891 | Fix compiler warnings about missing memcpy prototypes. |
3892 | ||
3893 | We no longer have the sparc assembly code in the header file any more, | |
3894 | so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would | |
3895 | break compiles on the sparc architectures when using gcc. | |
3896 | ||
3897 | In the libext2fs library, add the new field fs->now which if non-zero | |
3898 | is used instead of the system time when setting various filesystem | |
3899 | fields (last modified time, last write time, etc.) | |
3900 | ||
3901 | Fix gcc 4.01 complaints by adding a missing #include <string.h> to | |
3902 | ext2fs.h which is needed since the inline functions use memcpy(). | |
3903 | (Addresses Sourceforge Bug #1251062) | |
3904 | ||
3905 | Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in | |
3906 | the build system when building files in the util directory which are | |
3907 | needed during the build process. This avoids potential problems when | |
3908 | cross-compiling and some of the options specified in CFLAGS or LDFLAGS | |
3909 | are not recognized as valid by the host compiler. (Addresses | |
3910 | Sourceforge Bug #1261547) | |
3911 | ||
3912 | Clean up the blkid library by making the superblock and generic i/o | |
3913 | functions to be more generic. Clean up interface to the probe | |
3914 | function, and fix memory leak. Finallly, remove an unneeded reference | |
3915 | to probe.h in the lib/blkid/resolve.c | |
3916 | ||
3285a9c9 TT |
3917 | Add an ext2fs_read_bb_FILE regression test to confirm proper detection |
3918 | of invalid block #'s. | |
3919 | ||
34a2611c TT |
3920 | The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to |
3921 | indicate that the the function read/writes the memory location. | |
3922 | ||
3285a9c9 TT |
3923 | Fix various gcc -Wall complaints. |
3924 | ||
3925 | Add a dependency to make sure that the subdirectories are created | |
3926 | before creating all of the object files, in order to address parallel | |
3927 | build problem in the library Makefiles. (Addresses Sourceforge Bug: | |
3928 | #1261553) | |
3929 | ||
3930 | Add $(LDFLAGS) to the command line argument when generating an ELF or | |
3931 | Solaris shared library, to allow cross-compile and other builds that | |
3932 | might need to specify -L paths to needed libraries. (Addresses | |
3933 | Sourceforge Bug #1261549) | |
3934 | ||
bae55640 TT |
3935 | Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially |
3936 | intended for testing purposes. It allows an ext2/ext3 developer to | |
3937 | create very large filesystems using sparse files where most of the | |
3938 | block groups are not initialized and so do not require much disk | |
3939 | space. Eventually it could be used as a way of speeding up mke2fs and | |
3940 | e2fsck for large filesystem, but that would be best done by adding an | |
3941 | RO_COMPAT extension to the filesystem to allow the inode table to be | |
3942 | lazily initialized on a per-block basis, instead of being entirely | |
3943 | initialized or entirely unused on a per-blockgroup basis. | |
3944 | ||
6c09475b TT |
3945 | Fix backwards compatibility so e2fsprogs will better compile on Linux |
3946 | 2.0.35 systems. | |
3947 | ||
3948 | Make test scripts more robust against locale-related environment variables | |
3949 | ||
3950 | Fix type warning problem with sizeof() in ext2fs_open2(). | |
3951 | ||
3952 | Fix type warning problem with time_t in debugfs. | |

fea95ffc | 3955 | E2fsprogs 1.38 (June 30, 2005) |
1f965c8d TT |
3956 | ============================== |
3957 | ||
3958 | Fix blkid's test programs (built with "make check") compile correctly | |
3959 | even without "configure --enable-blkid-debug". | |
3960 | ||
3961 | Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict | |
3962 | type aliasing rules on newer gcc compilers. (Addresses Red Hat | |
3963 | Bugzilla ##161183.) | |
3964 | ||
3965 | Fix com_err library to make it more compatible with recent changes | |
3966 | made to the com_err library in MIT Kerberos V5 version 1.4. | |
3967 | (Addresses Sourcefroge Bug #1150146) | |
3968 | ||
3969 | General cleanup of messages printed by e2fsprogs programs for grammar, | |
3970 | consistency, and to make life easier for translators. Fixed a few | |
3971 | strings containing English that had not been marked as needing | |
3972 | translations. Removed strings that do not need to be translated, to | |
3973 | make life easier for translators. | |
3974 | ||
3975 | Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to | |
3976 | test to see if a device appears to be in use instead of just relying | |
3977 | on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594). | |
3978 | ||
3979 | Fix portability problem in the filefrag program affecting platforms | |
3980 | where the size of an integer is smaller than the size of a long. | |
3981 | (Addresses Debian Bug #309655) | |
3982 | ||
3983 | Mke2fs will now use a larger journal by default for filesystems | |
3984 | greater than 4GB. (128 MB instead of 32MB). | |
3985 | ||
3986 | Mke2fs will refuse to create filesystems greater than 2**31-1 blocks, | |
3987 | unless forced. This is to avoid signed vs. unsigned kernel bugs in | |
3988 | block numbers that still need to be fixed. | |
3989 | ||
3990 | The blkid program has a new option which will more efficiently search | |
3991 | for device when it is known (or expected) that only one matching | |
3992 | device will be found in the system, such as when doing a lookup by | |
3993 | UUID. | |
3994 | ||
3995 | Debian's e2fsprogs-specific initrd fragment will avoid including | |
3996 | unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD | |
3997 | and LD_LIBRARY_PATH, and filtering out libraries found in | |
3998 | /etc/ld.so.preload. (Addresses Debian Bug: #304003) | |
3999 | ||
4000 | Fixed a potential portability issue in the blkid programs for | |
4001 | architectures where the char type is unsigned. (Addresses Sourceforge | |
4002 | Bug: #1180585) | |
4003 | ||
4004 | Fix a bug in filefrag so that it doesn't falsely count an extra | |
4005 | discontinuity when the first block found is an indirect block. | |
4006 | (Addresses Debian Bug #307607). | |
4007 | ||
4008 | Fix blkid's recognition of cramfs filesystems, and enhance it to be | |
4009 | able to handle cramfs labels. | |
4010 | ||
4011 | Fix debugfs's stat command to not core dump when a filesystem is not | |
4012 | open. | |
4013 | ||
4014 | Fix e2fsck's handling of error conditions caused by the resize inode | |
4015 | claiming blocks that are also used by other inodes, a filesystem | |
4016 | corruption which was commonly caused by a bug in Fedora Core 3's | |
4017 | resize2fs program. | |
4018 | ||
4019 | Fixed bug in filefrag which caused it to fail on non-ext2/3 | |
4020 | filesystems. (Addresses Debian Bug: #303509) | |
4021 | ||
4022 | If the superblock last mount time indicates that the system clock may | |
4023 | not be accurate, then e2fsck will omit checking inodes' deletion time | |
4024 | field for indications of a potential corrupted orphaned inode list. | |
4025 | (Previously e2fsck only ommited these LOW_DTIME checks when the | |
4026 | superblock's last write time looked insane.) | |
4027 | ||
4028 | Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs. | |
4029 | (Addresses Debian bug #302200) | |
4030 | ||
4031 | Make the blkid library more paranoid about being run from setgid | |
4032 | programs, and to use __secure_getenv() from libc if it is available. | |
4033 | ||
4034 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
4035 | (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593 | |
4036 | and Sourceforge Bug: #1189803) | |
4037 | ||
4038 | Updated and fixed translations. | |
4039 | ||
4040 | Fixed various Debian packaging issues --- see debian/changelog for | |
4041 | details. | |
4042 | ||
4043 | Programmer's notes: | |
4044 | ------------------- | |
4045 | ||
4046 | Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been | |
4047 | changed to take an unsigned int for the bit number. Negative bit | |
4048 | numbers were never allowed (and didn't make any sense), so this should | |
4049 | be a safe change. This is needed to allow safe use of block numbers | |
4050 | greater than or equal to 2**31. | |
4051 | ||
4052 | The compile_et program will avoid recreating generated foo_err.c and | |
4053 | foo_err.h files if no changes are necessary. The compile_et program | |
4054 | will also atomically replace these files to avoid a potential parallel | |
4055 | build race problem on SMP systems. (Addresses Sourceforge Bug: | |
4056 | #1157933) | |
4057 | ||
4058 | Added a new function to the blkid library, blkid_probe_all_new(), | |
4059 | which only probes newly added disk devices, and change | |
4060 | blkid_find_dev_with_tag() to use this function so that when a | |
4061 | requested tag is not found, devices that were previously not checked | |
4062 | are searched before searching all devices in the system. | |
4063 | ||
4064 | Added new functions to the blkid library, blkid_dev_set_search() and | |
4065 | blkid_dev_has_tag(). | |
4066 | ||
4067 | E2fsck's problem strings can now use @m and @n as abbrevations for | |
4068 | "multiply-claimed" and "invalid", respectively. | |
4069 | ||
4070 | The e2fsprog.pot file now has an explanation of how the @-expansion | |
4071 | and %-expansion works, and strings in e2fsck/problem.c which contain @ | |
4072 | characters now have comments in e2fsprogs.pot with the @-expansion to | |
4073 | make life easier for translators. | |
4074 | ||
4075 | Fixed missing return values in the ext2fs library which could cause it | |
4076 | to return random garbage in certain error conditions. | |
4077 | ||
4078 | Allow the current time to be overriden via the E2FSCK_TIME environment | |
4079 | variable for use in regression tests. | |
4080 | ||
4081 | The test scrpit driver program now exits with a non-zero status if | |
4082 | there any of its test that it ran failed. | |
4083 | ||
4084 | Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge | |
4085 | Bug: #1157933) | |
4086 | ||
4087 | Fixed "make check" so that it compiles correctly even when e2fsprogs' | |
4088 | header files have not be installed in the system include directories. | |
4089 | (Addresses Sourceforge Bug: #1180572) | |
4090 | ||
4091 | Fixed gcc -Wall nits. | |
4092 | ||
4093 | ||
fd4b28ef TT |
4094 | E2fsprogs 1.37 (March 21, 2005) |
4095 | =============================== | |
4096 | ||
4097 | Add support for checking the validity of Extended Attributes stored in | |
4098 | inodes to e2fsck. | |
4099 | ||
4100 | Add support for dumping the contents of large inodes to debugfs, | |
4101 | including the extended attributes stored in inodes. | |
4102 | ||
4103 | Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that | |
4104 | when we create a new inode we make sure that the extra information in | |
4105 | the inode (any extra fields in a large inode and any ea-in-inode | |
4106 | information) is initialized correctly. This can take place when | |
4107 | mke2fs creates the root and lost+found directory, when e2fsck creates | |
4108 | a new root inode or a new lost+found directory, and when the user uses | |
4109 | the debugfs write, mknod, or mkdir commands. Otherwise, the newly | |
4110 | create inode could inherit garbage (or old EA information) from a | |
4111 | previously deleted inode. | |
4112 | ||
4113 | Fixed a bug in e2fsck so it would notice if a file with an extended | |
4114 | attribute block was exactly 2**32 blocks, such that i_blocks wrapped | |
4115 | to zero. | |
4116 | ||
4117 | Added support to filefrag to detect files which are using the new | |
4118 | experimental file extents format, and use the non-ext2 algorithm in | |
4119 | that case. Fixed a bug to avoid reporting a false discontinuity if | |
4120 | there is one or more unallocated blocks at the beginning of a file. | |
4121 | ||
4122 | Duplicated a check for noticing whether or not the number of blocks | |
4123 | (given a certain blocksize) is greater than 2**32 when the | |
4124 | BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This | |
4125 | allows mke2fs to automatically use a larger blocksize when creating a | |
4126 | filesystem on a very large device when run on systems that do not | |
4127 | support BLKGETSIZE64. | |
4128 | ||
4129 | Fix the I18N build which was broken in e2fsprogs 1.36 because the | |
4130 | build system had been switched to treat the .gmo files as shipped | |
4131 | files (for backwards compatibility with systems that have older GNU | |
4132 | I18N tools installed), but the gen_tarball.in script was still | |
4133 | removing the .gmo files from the official source distribution. | |
4134 | ||
4135 | Fixed various Debian packaging issues --- see debian/changelog for | |
4136 | details. (Addresses Debian Bugs ##296769, #299341) | |
4137 | ||
4138 | Programmer's notes: | |
4139 | ------------------- | |
4140 | ||
4141 | Added new functions to the e2p library which convert between a string | |
4142 | and os_type: e2p_os2string() and e2p_string2os(), and used them to | |
4143 | make the generated binaries more compact. | |
4144 | ||
4145 | Fixed a compile-time error on Darwin systems. | |
4146 | ||
4147 | Cleaned up the lib/ext2fs Makefile slightly. | |
4148 | ||
4149 | ||
3eee5e9e TT |
4150 | E2fsprogs 1.36 (February 4, 2005) |
4151 | ================================= | |
2b0dc0ac TT |
4152 | |
4153 | All of the patches that were applied to Fedore Core 3's | |
4154 | e2fsprogs-1.35-11.2 have been integrated, although sometimes with a | |
4155 | lot of bug fixes first. Users of Fedora Core 3 are strongly | |
4156 | encouraged to upgrade to e2fsprogs 1.36 as soon as possible. | |
4157 | ||
4158 | Add support for filesystem with the online resizing via resize inode | |
4159 | feature. Fixed numerous bugs from the Fedora patches. The Fedora | |
4160 | patches also didn't bother to do any consistency checking on the | |
4161 | resize inode, or add any tests to the regression test suite. The "-R | |
4162 | resize=4g" option to mke2fs was a no-op in the Fedora patches, despite | |
4163 | being listed in mke2fs's usage message. All of these shortcomings | |
4164 | have been corrected. | |
4165 | ||
4166 | E2fsck can also also fix filesystems trashed by Fedora's resize2fs | |
4167 | program. In order to do this, the user must run the commands: | |
4168 | ||
d0a3b46c | 4169 | debugfs -w /dev/hdXXX -R "features ^resize_inode" |
2b0dc0ac TT |
4170 | e2fsck -f /dev/hdXXX |
4171 | ||
4172 | Optionally, the ext2prepare command can be used to re-enable online | |
4173 | resizing after the filesystem has been fixed. | |
4174 | ||
4175 | The fsck program will now accept an optional filedescriptor argument | |
4176 | to the -C option. (The Fedora version of this patch would sometimes | |
4177 | cause fsck to ignore a parameter on fsck's command line in some rare | |
4178 | cases, sigh.) | |
4179 | ||
dc256973 TT |
4180 | Make sure e2fsprogs doesn't write garbage into the reserved portion of |
4181 | large inodes. | |
4182 | ||
4183 | Make sure resize2fs releases the blocks belonging to the old inode | |
4184 | table blocks when moving the inode table. (Addresses Debian Bug: | |
4185 | #290894) | |
4186 | ||
4187 | Skip the r_resize_inode test if resize2fs is not compiled (due to | |
4188 | configure --disable-resizer) | |
4189 | ||
4190 | E2fsck now checks the summary filesystem accounting information, and | |
4191 | if any of the information is obviously wrong, it will force a full | |
4192 | filesystem check. (Addresses Debian Bug #291571) | |
4193 | ||
4194 | Fix e2fsck to not complain when the resize_inode feature is enabled, | |
4195 | s_reserved_gdt_blocks is zero, and there is no DIND block allocated in | |
4196 | the resize inode. | |
4197 | ||
8ceb55f0 TT |
4198 | Fix e2fsck to note delete symlinks that contain an extended attribute |
4199 | after the ext_attr feature flag has been cleared. (Addresses Red Hat | |
4200 | Bugzilla #146284). | |
4201 | ||
dc256973 TT |
4202 | Add new utility program, copy_sparse.c, which is very useful |
4203 | for dealing with large sparse files (such as e2image files). | |
4204 | ||
4205 | Add support for jnl_blocks[] for debugfs's set_super_value. | |
4206 | ||
4207 | Fix filefrag so that it works correctly with sparse files. | |
4208 | ||
3eee5e9e TT |
4209 | Filefrag -v will print first and last blocks. |
4210 | ||
dc256973 TT |
4211 | Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs |
4212 | and dumpe2fs. | |
4213 | ||
8ceb55f0 TT |
4214 | Add mke2fs support so that it can support filesystems larger than 4TB |
4215 | automatically, by retrying with a 4k blocksize if the device size is | |
4216 | too big to be expressed using a 1k blocksize. (Addresses Sourceforge | |
4217 | bug #1106631) | |
4218 | ||
dc256973 TT |
4219 | Change blkid to test for NTFS first because Windows sometimes doesn't |
4220 | clear enough of the parition to confuse the probing routines into | |
4221 | thinking the old filesystem type is still valid. (Addresses Debian | |
4222 | Bug #291990) | |
4223 | ||
66fa0de8 TT |
4224 | Add support for swap partition label and uuid's in the blkid library. |
4225 | ||
dc256973 TT |
4226 | Add support to the blkid library to recognize Oracle ASM volumes. |
4227 | ||
4228 | Make blkid -t display all devices that match the specified criteria, | |
8ceb55f0 TT |
4229 | not just the first one, and work more consistently when the blkid |
4230 | cache file is not available or set to /dev/null. (Addresses Debian | |
4231 | Bug #290530 and #292425) | |
dc256973 | 4232 | |
2b0dc0ac TT |
4233 | Badblocks will now correctly display block numbers greater than |
4234 | 999,999,999 in its progress display. | |
4235 | ||
4236 | The tune2fs program will not allow the user from setting a ridiculous | |
4237 | number of reserved blocks which would cause e2fsck to assume the | |
4238 | superblock was corrupt. E2fsck's standards for what is a ridiculous | |
4239 | number of reserved block has also been relaxed to 50% of the blocks in | |
4240 | the filesystem. | |
4241 | ||
4242 | The blkid library will return vfat in preference to msdos, and ext3 in | |
4243 | preference to ext2 (if the journalling flag is set) so that mount will | |
4244 | do the right thing. (Addresses Debian bug #287455) | |
4245 | ||
4246 | Mke2fs will now use the -E option for extended options; the old -R | |
4247 | (raid options) option is still accepted for backwards compatibility. | |
4248 | Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707) | |
4249 | ||
4250 | Mke2fs will now accept a size in megabytes, gigabytes, and other units | |
4251 | (via "32m" or "4g" on the command line) if the user finds this more | |
4252 | convenient than specifying a block count. | |
4253 | ||
4254 | Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode | |
4255 | cache conherency problem. | |
4256 | ||
4257 | Debugfs now supports a new command, set_inode_field, which allows a | |
4258 | user to manually set a specific inode field more conveniently, as well | |
4259 | as set entries in the indirect block map. | |
4260 | ||
4261 | Debugfs's set_super_value command has been enhanced so that the user | |
4262 | can set most superblock fields, including the date/time fields and | |
4263 | some of the more newsly added superblock fields. | |
4264 | ||
4265 | E2fsprogs programs now accept an offset to be passed to the file | |
4266 | specifiers, via the syntax: "/tmp/test.img?offset=1024". | |
4267 | ||
4268 | E2fsprogs programs will now accept blocksizes up to 65536; kernel | |
4269 | support on the x86 doesn't exist for now, but it can be useful on | |
8ceb55f0 TT |
4270 | other architectures with page sizes greater than 4k. There are 2.6 |
4271 | kernel patches out there which enable this, but they are of this | |
4272 | writing still experimental. | |
2b0dc0ac | 4273 | |
4ee558fc TT |
4274 | The e2image command now takes the -s option which will scramble |
4275 | directory entries for raw image files. | |
4276 | ||
4277 | Fix a file descriptor leak in the filefrag program. | |
4278 | ||
4279 | Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not | |
4280 | present. | |
4281 | ||
2b0dc0ac TT |
4282 | Fix bug in debugfs where kill_file would lead to errors when deleting |
4283 | devices and symlinks. (Sourceforge Bugs #954741 and #957244) | |
4284 | ||
4285 | Fix bug in the blkid library when detecting the ocfs1 filesystem | |
4286 | ||
4287 | Remove obsolete EVMS 1.x and a.out DLL support. | |
4288 | ||
4289 | E2fsck will attempt to recover from a journal containing illegal blocks. | |
48301129 TT |
4290 | |
4291 | Fixed two potential ordering constraint problems in e2fsck which might | |
4292 | cause the filesystem to be corrupted if e2fsck is interrupted during a | |
4293 | (extremely narrow) race window. Thanks to Junfeng Yang from the | |
4294 | Stanford Metacompilation group for pointing this out. | |
4295 | ||
4296 | Fixed bug in e2fsck where it would not accurately detect whether or | |
4297 | not the system is running on adaptor if the ACPI device representing | |
4298 | the AC adapter didn't correspond to the what was used on IBM | |
4299 | Thinkpads. | |
4300 | ||
4301 | Change e2fsck to accept directories greater than 32MB. | |
4302 | ||
4303 | Fix e2fsck so that a checkinterval of zero disables a time-based check | |
4304 | of the filesystem. | |
4305 | ||
4306 | Debugfs will check the DEBUGFS_PAGER enviroment variable in preference | |
4307 | to the PAGER environment variable. (Addresses Debian Bug #239547) | |
4308 | ||
4309 | Tune2fs will not mark rewrite the superblock if the feature bitmasks | |
4310 | are not modified. | |
4311 | ||
4312 | The debugfs program will set the filetype information when creating a | |
4313 | link. | |
4314 | ||
4315 | Add debugfs -d option to use a separate source of data blocks when | |
4316 | reading from an e2image file. | |
4317 | ||
4318 | Add e2image -I option which allows the e2image metadata to be | |
4319 | installed into a filesystem. | |
4320 | ||
4321 | Fixed bug in the badblocks program which caused "done" to always | |
4322 | appear in english even when a translation was available. (Addresses | |
4323 | Debian Bug #252836) | |
4324 | ||
4325 | The blkid program has a new option -o which controls the output format | |
4326 | of the blkid program; this is makes blkid more convenient to use in | |
4327 | shell scripts. | |
4328 | ||
4329 | Fix a minor bug in uuid library, which was not using the full 14 bits | |
4330 | of clock sequence when generating UUID's. | |
4331 | ||
4332 | Fix a Y8.8888K problem in the uuid library. | |
4333 | ||
4334 | Logsave now creates a new session id for itself to avoid getting | |
4335 | killed by init whan transitioning between init levels. | |
4336 | ||
4337 | Change the licensing of the UUID library to be the 3-clause BSD-style | |
4338 | license; this allows Apple to use the uuid library in Darwin. | |
4339 | ||
4340 | Add ocfs and ocfs2 probe support into the blkid library. | |
4341 | ||
4342 | Fix a memory and file descriptor leak in the blkid library. | |
4343 | ||
4344 | The blkid library will revalidate the device if the system time is | |
4345 | earlier than last verification time of the device, since that | |
4346 | indicates that the system time is probably nottrustworthy. | |
4347 | ||
4348 | The blkid library will override the default location of the blkid.tab | |
4349 | file by the BLKID_FILE environment variable, if it is available. | |
4350 | ||
4351 | Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6. | |
4352 | ||
4353 | Add various portability fixes for lame new versions of glibc, Darwin | |
4354 | and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian | |
2b0dc0ac TT |
4355 | Bugs #239934, #264630, #269044, #255589, #289133) |
4356 | ||
4357 | Add support for Windows 9x/NT under Cygwin. | |
48301129 TT |
4358 | |
4359 | Updated and clarified various man pages. (Addresses Debian Bugs #236383, | |
2b0dc0ac | 4360 | #241940, #238741, #242995, #256669, #268148, #256760, #273679) |
48301129 TT |
4361 | |
4362 | Updated and fixed translations. (Addresses Debian bugs #244105, #262836) | |
4363 | ||
4364 | Update the rpm spec files so that it works better with Fedora core 2 | |
4365 | and RH9. | |
4366 | ||
4367 | Fixed various Debian packaging issues (see debian/changelog). In | |
4368 | particular, fixed the Debian initrd scripts. (#241183, #248050, | |
4369 | #253595, #247775) | |
4370 | ||
4371 | ||
4372 | Programmer's notes: | |
4373 | ------------------- | |
4374 | ||
2b0dc0ac | 4375 | Fixed various gcc -Wall warnings. |
48301129 TT |
4376 | |
4377 | The uuid library now has new functions uuid_unparse_upper() and | |
4378 | uuid_unparse_lower() which forces the case of the hex digits to be | |
4379 | upper case, or lower case. | |
4380 | ||
4381 | The build process has been speeded up by enhancing the subst program | |
4382 | to update the modtime on the generated files even when the generated | |
4383 | file hasn't changed. | |
4384 | ||
4385 | The uuid library now uses C99 stdint.h types instead of custom types. | |
4386 | ||
4387 | Updated config.guess and config.sub with newer versions from the FSF. | |
4388 | ||
4389 | Removed out of date .cvsignore files from the source distribution. | |
4390 | ||
2b0dc0ac TT |
4391 | The ext2fs_unlink() function will return an error if both the name and |
4392 | inode number are unspecified, to avoid doing something surprising | |
4393 | (such as unconditionally deleting the first directory entry). | |
4394 | Directory entries are now deleted by coalescing them with the previous | |
4395 | directory entry if possible, to avoid directory fragmentation. This | |
4396 | is not an issue with the e2fsprogs suite, but may be a problem for | |
4397 | some of the users of libext2fs, such as e2tools. | |
4398 | ||
4399 | Add support for version numbers of the form "1.36-rc1". | |
4400 | ||
48301129 TT |
4401 | Fix build of mke2fs.static. |
4402 | ||
dc256973 TT |
4403 | Add basic ext2fs library support for large (EA in inode) inodes. |
4404 | ||
48301129 TT |
4405 | The test_io mechanism can now abort after n reads or writes to a |
4406 | particular block. The block is specified by TEST_IO_BLOCK environment | |
4407 | variable, and the read/write count by the TEST_IO_READ_ABORT and | |
4408 | TEST_IO_WRITE_ABORT environment variables. The block data is now only | |
4409 | dumped if the 0x10 bit is set in TEST_IO_FLAGS. | |
4410 | ||
4411 | UUID_DEFINE() in the uuid library now creates a static variable, with | |
4412 | __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can | |
4413 | be used in header files. | |
4414 | ||
2b0dc0ac TT |
4415 | Add support for the install-strip and install-shlibs-strip targets, as |
4416 | suggested by the GNU coding guielines. "make install" no longer | |
4417 | strips the binaries which are installed. | |
4418 | ||
3eee5e9e TT |
4419 | Remove support for the --enable-old-bitops configure option which was |
4420 | only for very old sparc systems. | |
4421 | ||
4422 | Remove support for --enable-clear-htree; this was only needed during | |
4423 | the early development of the htree patch. | |
4424 | ||
2b0dc0ac TT |
4425 | Use Linux-kernel-style makefile output so it is easier to see compiler |
4426 | warnings. | |
4427 | ||
4428 | Update gettext files to version 0.14.1. | |
4429 | ||
4430 | Update to use autoconf 2.5x. | |
4431 | ||
4432 | Improved support for compiling e2fsprogs under dietlibc. | |
4433 | ||
4ee558fc TT |
4434 | Make e2fsprogs portable to Solaris and FreeBSD systems. |
4435 | ||
8ceb55f0 TT |
4436 | Add blkid_verify(), blkid_get_library_version(), and |
4437 | blkid_parse_version_string() functions to the blkid library. | |
dc256973 TT |
4438 | |
4439 | Add pkg-config files for e2fsprogs's libraries. | |
4440 | ||
4441 | Fix "make uninstall" to so that it removes everything that is installed. | |
4442 | ||
3eee5e9e TT |
4443 | Add a configure --enable-maintainer-mode option which enables the |
4444 | makefile rules to rebuild the configure script from configure.in, and | |
4445 | to reubuild the .gmo files in po directory. | |
4446 | ||
4447 | Drop the sparc assembly bitwise operations; it's less efficient | |
4448 | than the GCC 3.4 compile code and triggers compiler warnings on | |
4449 | sparc64. Thanks to Matthias Andree for his analysis and suggestions. | |

4453 | E2fsprogs 1.35 (February 28, 2004) |
4454 | ================================== | |
4455 | ||
48301129 | 4456 | E2fsck has a new -k option, which in conjunction with the -c options, |
b70b1167 TT |
4457 | preserves the existing badblocks list. |
4458 | ||
48301129 | 4459 | Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d. |
b70b1167 TT |
4460 | |
4461 | E2fsprogs will now deal correctly with symlinks that contain | |
4462 | extended attribute information, which can be created using SE Linux. | |
4463 | (Addresses Debian Bug #232328) | |
4464 | ||
4465 | Remove a double longjump into an invalid stack frame bug in e2fsck. | |
4466 | (This was during an abort sequence, which normally worked on Linux and | |
4467 | caused a core dump on other operating systems.) | |
c4c30b20 | 4468 | |
1daf7585 TT |
4469 | Fix NLS bug in e2fsck, by avoiding trying to expand an empty string |
4470 | (the NLS library will replace "" with the .po header information). | |
4471 | ||
c4c30b20 TT |
4472 | Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core |
4473 | dump due to a division by zero error. (Addresses Debian bug #207082) | |
4474 | ||
151a7162 TT |
4475 | Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem |
4476 | when reconnecting a directory requires creating a lost+found | |
4477 | directory. (Addresses Debian bug #219640). | |
4478 | ||
4479 | Fixed a bug where e2fsck would bomb out if a journal needed to be | |
4480 | replayed when using an alternate superblock. | |
4481 | ||
48301129 | 4482 | E2fsck will give an extra grace period before actually forcing a check |
c4c30b20 TT |
4483 | if the laptop is running on battery. The next time fsck runs while |
4484 | the system is on the AC mains, or after the grace period is exceeded, | |
4485 | the filesystem will be checked. (Addresses Debian bug #205177) | |
4486 | ||
4487 | E2fsck will inform the user when there are 5 or fewer mounts before a | |
4488 | filesystem check will be forced. (Addresses Debian bug #157194) | |
4489 | ||
4490 | Fix e2fsck's handling of corrupted indirect blocks in the bad block. | |
4491 | We now correctly handle the case where there is an overlap between a | |
4492 | block group descriptor or a superblock and a bad block indirect block. | |
4493 | In the case where the indirect block is corrupted, we now suggest | |
4494 | "e2fsck -c". | |
4495 | ||
1daf7585 TT |
4496 | Fix byte swap bugs in e2fsck that caused the journal backup location |
4497 | in the superblock and symlinks created by SE Linux to be cleared | |
4498 | by e2fsck on big-endian machines. (Addresses Debian bug #228723) | |
4499 | ||
c4c30b20 TT |
4500 | E2fsck -c now replaces the current list of bad blocks with the ones |
4501 | found by badblocks. | |
4502 | ||
4503 | Fix bugs in e2fsck and tune2fs which could cause a core dump if a | |
4504 | non-existent LABEL or UUID specifier is to e2fsck or tune2fs. | |
4505 | ||
4506 | Fix a potential bug in e2fsck which could cause it to core dump when | |
4507 | trying to print the location of the backup superblock. | |
4508 | ||
4509 | Protect against a potential core dump in e2fsck when printing a | |
4510 | message about backup superblocks. | |
858dd7b1 | 4511 | |
6826bde5 TT |
4512 | Add support for backing up the journal inode location in the |
4513 | superblock. E2fsck will automatically save the journal information in | |
4514 | the superblock if it is not there already, and will use it if the | |
4515 | journal inode appears to be corrupted. ext2fs_add_journal_inode() | |
4516 | will also save the backup information, so that new filesystems created | |
4517 | by mke2fs and filesystems that have journals added via tune2fs will | |
4518 | also have journal location written to the superblock as well. | |
4519 | Debugfs's logdump command has been enhanced so that it can use the | |
4520 | journal information in the superblock. | |
c4c30b20 TT |
4521 | |
4522 | E2fsck will now update all superblocks when moving the journal inode. | |
6826bde5 TT |
4523 | |
4524 | Shrink the size of the e2fsck executable by moving some initialized | |
4525 | variables to the BSS segment. | |
4526 | ||
4527 | E2fsck will avoid printing the ^A and ^B characters which bracket the | |
4528 | progress bar when stdout and stdin are a tty device instead of a pipe | |
4529 | to another program. (Addresses Debian bug #204137) | |
4530 | ||
151a7162 TT |
4531 | Debugfs's mkdir command will automatically expand the directory if |
4532 | necessary. (Addresses Debian Bug: #217892) | |
4533 | ||
4534 | Fixed a bug in debugfs so that copying a file from /dev/null uses the | |
4535 | correct mode bits. (Addresses Debian Bug: #217456) | |
4536 | ||
4537 | If the environment variables DEBUFS_PAGER and PAGER are not set, | |
4538 | debugfs now searches for the appropriate pager to use, beginning with | |
2b5ddd75 | 4539 | /usr/bin/pager, and then falling back to 'more' and 'less'. |
1daf7585 TT |
4540 | (Addresses Debian bug #221977) |
4541 | ||
b70b1167 TT |
4542 | Debugfs will now support 2.6 device numbers where the major or minor |
4543 | number may be larger than 255. (Addresses Sourceforge bug #865289) | |
4544 | ||
48301129 TT |
4545 | Fix debugging printf in resize2fs. (Addresses Debian Bug #271605) |
4546 | ||
1daf7585 TT |
4547 | Chattr now stops processing options when it sees '--'. (Addresses |
4548 | Debian bug #225188) | |
151a7162 | 4549 | |
858dd7b1 TT |
4550 | Fix regression tests so they work correctly when e2fsprogs is compiled |
4551 | with configure --disable-htree. | |
4552 | ||
1daf7585 TT |
4553 | Fix bug in uuid library when there is no network card and the library |
4554 | is generating a time-based uuid. The random MAC address was not | |
4555 | correctly generated to be a multicast address. | |
4556 | ||
858dd7b1 | 4557 | Add compile_et extensions from Heimdall that were missed the first time |
48301129 | 4558 | around. |
858dd7b1 TT |
4559 | |
4560 | Fix bug in badblocks when using O_DIRECT; we need to make sure that | |
4561 | we're reading from an offset which is page aligned. For read-only and | |
4562 | read-write tests, we try to recover after an error so that we can | |
4563 | continue reading on page-aligned boundaries. (Addresses Debian Bug | |
4564 | #203713) | |
4565 | ||
b70b1167 TT |
4566 | Badblocks now checks 64 blocks at a time instead of 16. (Addresses |
4567 | Debian bug #232240) | |

4576 | Programmer's notes: | |
4577 | ------------------- | |
4578 | ||
b70b1167 TT |
4579 | Fixed a build problem so that e2fsprogs would compile with the |
4580 | --enable-profile option to configure selected. (Addresses Sourceforge | |
4581 | bug #811408) | |
4582 | ||
4583 | Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat | |
4584 | Bugzilla Bug #112448) | |
4585 | ||
c4c30b20 TT |
4586 | Centralize code which calculates the location of the superblock |
4587 | and block group descriptors so that it is in a single library routine. | |
4588 | ||
6826bde5 TT |
4589 | Added two new functions, ext2fs_file_open2() and |
4590 | ext2fs_inode_io_intern2() which take a pointer to an inode structure. | |
4591 | ||
4592 | Fix compile_et to output the correct prototype for | |
4593 | initialize_xxx_err_table_r() in the header file. (Addresses Debian | |
4594 | bug #204332) | |
4595 | ||
4596 | In the lib/et makefile, make sure com_err.info is deleted on "make clean". | |
4597 | ||
858dd7b1 TT |
4598 | Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if |
4599 | present. This is for when we try stuffing an int into void * pointer. | |
4600 | ||
4601 | Fix type-punning which can cause gcc 3.x to miscompile code by getting | |
4602 | confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(), | |
4603 | and ext2fs_resize_mem() all now take a 'void *' instead of a 'void | |
4604 | **'. The EVMS code uses an ugly union approach since we don't want to | |
4605 | modify the EVMS interfaces. | |
4606 | ||
4607 | Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to | |
4608 | aid build process on systems can use invoke GNU make as "gmake". | |
4609 | ||
c4c30b20 TT |
4610 | Added regression testing for mke2fs. |
4611 | ||
4612 | Fixed gcc -Wall nitpicks. | |
4613 | ||
1daf7585 TT |
4614 | Fixed various compiler warnings. |
4615 | ||
4616 | Add portability fixes for FreeBSD and for using fsctl under Darwin to | |
4617 | support ext2 ioctl's. | |
4618 | ||
858dd7b1 | 4619 | |
9c7ec178 TT |
4620 | E2fsprogs 1.34 (July 25, 2003) |
4621 | =============================== | |
4622 | ||
4623 | Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in | |
4624 | a tight loop while waiting for a child fsck to exit in some cases. | |
4625 | This burns CPU times which slows down the low-level filesystem check. | |
4626 | ||
4627 | Added code to mke2fs to assure that the default block size for a | |
4628 | filesystem is at least as big as the sector size of the device, if it | |
4629 | can be determined. | |
4630 | ||
4631 | Changed mke2fs and resize2fs to round the default size of a filesystem | |
4632 | to be an even multiple of the VM pagesize in order to avoid a Linux | |
4633 | kernel bug introduced when the storage of the buffer cache was moved | |
4634 | into the page cache. | |
4635 | ||
4636 | Mke2fs will warn the user when creating a filesystem with journaling | |
4637 | and a blocksize greater than 4096. (Addresses Debian bug #193773) | |
4638 | ||
4639 | Fixed a bug in resize2fs which caused it to fail on filesystems with a | |
4640 | non-empty bad block list. Resize2fs now discards any blocks on the | |
4641 | badblock list which are no longer part of the filesystem as the result | |
4642 | of a filesystem shrink. (Note: this means that shrinking and then | |
4643 | enlarging a filesystem is no longer a reversible operation; | |
4644 | information about bad blocks in the part of the filesystem which is to | |
4645 | be chopped off will be lost.) | |
4646 | ||
4647 | Changed resize2fs so the user can use prefixes to specify the units of | |
4648 | the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), | |
4649 | and to make the error and informational messages explicitly display | |
4650 | the blocksize used by the filesystem, in order to avoid confusion. | |
4651 | (Addresses Debian bug: #189814) | |
4652 | ||
4653 | Added a new debugfs command, dump_unused, which dumps the contents of | |
4654 | all unused blocks to stdout. (Useful as an emergency try-to-find | |
4655 | deleted data command.) | |
4656 | ||
4657 | Added a new debugfs command, imap, which prints the location of a | |
4658 | specified inode in the inode table. | |
4659 | ||
4660 | Fixed a bug in the badblocks program which caused it to use one bit of | |
4661 | randomness in its non-destructive read/write test, instead of using a | |
4662 | full 8 bits of randomness. | |
4663 | ||
4664 | Added a new option (-t) to badblocks, which allows the user to control | |
4665 | the test pattern(s) used when checking a disk. | |
4666 | ||
4667 | The blkid probe function now more correctly detects UDF filesystems. | |
4668 | ||
4669 | Fixed a bug in the blkid library which caused it to not update its | |
4670 | cache if a filesystem changes from having a label to not having a | |
4671 | label. | |
4672 | ||
4673 | Fixed a bug in the blkid library wihch could avoid an infinite loop | |
4674 | in blkid_find_dev_with_tag() if /proc is not mounted and there the | |
4675 | /etc/blkid.tab file has not yet been created. | |
4676 | ||
4677 | Fixed the badblocks program so that the destructive read/write test | |
4678 | honors the -c option, and to use O_DIRECT when possible to avoid | |
4679 | thrashing the system block buffer cache. | |
4680 | ||
4681 | Fixed various NLS issues. | |
c8a40402 | 4682 | - Added Czech and Swedish translations |
9c7ec178 TT |
4683 | - Removed testing NYC translation |
4684 | - Fixed NLS support for message abbrevations in e2fsck | |
4685 | - Remove de-utf.po, since we shouldn't have two versions using different | |
4686 | charset encodings. | |
4687 | - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to | |
4688 | simplify the statistics reporting in e2fsck. | |
4689 | ||
4690 | Changed configure.in so that its defaults for *BSD systems no longer | |
4691 | build an fsck wrapper, and not to install in /usr/local by default. | |
4692 | ||
4693 | Fixed some minor spelling errors/typo's in e2fsck and the configure | |
4694 | script. | |
4695 | ||
4696 | Fixed various Debian packaging issues (see debian/changelog). | |
4697 | ||
4698 | Updated and clarified man pages. (Addresses Debian Bug #195616) | |
4699 | ||
4700 | Programmer's notes: | |
4701 | ------------------- | |
4702 | ||
4703 | Fix gcc -Wall nitpicks. | |
4704 | ||
4705 | Updated gettext implementation used by e2fsprogs to 0.11.5, and enable | |
4706 | NLS support by default. (Added partial workaround for gettext/Darwin | |
4707 | incompatibility problems.) | |
4708 | ||
4709 | Added full MIT KRB5 and Himdall compaibility support to the com_err | |
4710 | library and the compile_et program. (Addresses Debian bug #191900) | |
4711 | ||
4712 | Added the blkid_known_fstype() function to the blkid library, which | |
4713 | returns true if it is passed a filesystem type which is recognized by | |
4714 | the blkid probing functions. | |
4715 | ||
4716 | Improved the documentation for the blkid library. | |
4717 | ||
4718 | Added the ext2fs_get_device_sectsize() function the the ext2fs library, which | |
4719 | returns the hardware sector size of a device, if it is available. | |
4720 | ||
4721 | Added a dependency in the blkid library's .so file to the uuid | |
4722 | library, since the former uses the latter. (Addresses Debian bug | |
4723 | #194094) | |
4724 | ||
4725 | Added --with-diet-libc and --disable-evms to the configure script. | |
4726 | ||
4727 | Fixed a minor memory leak in the badblocks program. | |
4728 | ||
4729 | Fixed a portability problem in tune2fs --- not all systems have strptime(). | |
4730 | ||
4731 | Fixed a portability problem in debugfs with the use of getopt() more | |
4732 | than once. Old-style BSD, new-style BSD, and Linux C libraries all do | |
4733 | things differently. | |
4734 | ||
4735 | Add support Windows support to ext2fs_get_device_size(). | |
4736 | ||
4737 | Added (normally disabled) debugging code to the Unix I/O manager which | |
4738 | causes it to disable all userspace caching if the NO_IO_CACHE is | |
4739 | defined. | |
4740 | ||
4741 | Changed the test I/O manager so it can always be linked into e2fsck, | |
4742 | mke2fs, and tune2fs if enabled via --enable-test-io-debug to the | |
4743 | configure script. The test I/O manager will only print any debugging | |
4744 | information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment | |
4745 | variables are set, which specifies which I/O operations are logged and | |
4746 | a block number to watch, respectively. The log messages are sent to | |
4747 | stderr by default, unless a filename is specified via the | |
4748 | TEST_IO_LOGFILE environment variable. | |
4749 | ||
4750 | ||
71df0dc3 | 4751 | E2fsprogs 1.33 (April 21, 2003) |
9c7ec178 | 4752 | =============================== |
508d7f3c | 4753 | |
ba142c1b TT |
4754 | Added a new utility program, logsave, which captures the output of a |
4755 | command in a log file, even if the containing directory hasn't been | |
4756 | mounted yet (in which case the it saves the output in memory until it | |
4757 | can write out the logfile). This is useful for capturing the | |
4758 | output of fsck during the boot sequence. | |
4759 | ||
4760 | Fixed some portability problems that were causing problems under | |
4761 | the Cygwin32 environment. | |
4762 | ||
4763 | Mke2fs now interprets a negative number to the -b option as a minimum | |
4764 | block size. | |
4765 | ||
4766 | Fixed a bug in mke2fs which was incorrectly checking the argument to | |
4767 | the -g option if the default block size was used. (Addresses Debian | |
4768 | bug #188319) | |
4769 | ||
4770 | Fsck now explicitly ignores tmpfs and devpts, and it will complain if | |
4771 | it can not find filesystem checkers for jfs, reseirfs, and xfs. | |
4772 | ||
4773 | E2fsck now updates the global free block and inode counters from the | |
4774 | block group specific counters quietly. This is needed for an | |
4775 | experimental patch which eliminates locking the entire filesystem when | |
4776 | allocating blocks or inodes; if the filesystem is not unmounted | |
4777 | cleanly, the global counts may not be accurate. | |
4778 | ||
4779 | Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS | |
4780 | 2.0 is not yet supported; this only pulled in the bug fixes: fixed | |
4781 | possible hangs caused by bugs in calling waitpid, and not setting the | |
4782 | pipe to non-blocking mode; also fixed a file descriptor leak; made | |
4783 | sure all functions call log entry/exit functions.) | |
4784 | ||
4785 | Badblocks now flushes its output file as bad blocks are discovered. | |
4786 | ||
4787 | The uuid library is now more paranoid about assuming the correctness | |
4788 | of the /dev/random device; it mixes in a stream of bytes from | |
4789 | random/srandom, just in case. | |
4790 | ||
39d38b05 | 4791 | Update Debian files to reflect the fact that I am now the Debian |
ba142c1b TT |
4792 | maintainer of e2fsprogs. Other various Debian-specific packaging |
4793 | cleanups. | |
39d38b05 TT |
4794 | |
4795 | Move the source tarball generation functions from the top-level | |
4796 | makefile to the util/gen-tarball script. | |
4797 | ||
4798 | Updated the Turkish .po translation file. | |
4799 | ||
1daf7585 | 4800 | Added Heimdal and MIT krb5 extensions to the com_err library to make |
39d38b05 TT |
4801 | it more compatible with com_err libraries from those distributions. |
4802 | ||
4803 | Changed dumpe2fs to always display the superblock fields relating to | |
4804 | the journalling and/or directory indexing feature even if those | |
4805 | features are not enabled. | |
4806 | ||
508d7f3c TT |
4807 | Updated and clarify copyright statement vis-a-vis alpha releases of |
4808 | e2fsprogs. | |
4809 | ||
4810 | The ss library will now try to dynamically link to the readline | |
4811 | library and use it if it is present in the system. This means that | |
ba142c1b TT |
4812 | the debugfs program now has line editing and history features. The |
4813 | SS_READLINE_PATH environment variable is used to find a readline or | |
4814 | readline-compatible library. | |
3809bf1d | 4815 | |
e5dced7f TT |
4816 | E2fsck now finds most duplicate filenames (all when rebuilding all |
4817 | directories via the -D option) and offers to delete or rename | |
4818 | duplicate filenames/directory entries. (Addresses Debian Bug #176814). | |
4819 | ||
4820 | Fix bug in e2image. When writing out a raw image file, include data | |
4821 | blocks from symlinks that do not store the symlink within the inode. | |
4822 | ||
3809bf1d TT |
4823 | Fix bug in resize2fs which incorrectly moved the block and inode |
4824 | bitmaps for sparse superblock filesystems and incorrectly marked | |
4825 | blocks as in use. (Addresses Debian bug #174766) | |
4826 | ||
4827 | Added a new shared library, the blkid library, which efficiently | |
4828 | allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL | |
4829 | and UUID filesystem specifiers without needing to search all of the | |
4830 | devices in the system. Instead, the device is looked up in a cache | |
4831 | file, and then verified to make sure the blkid cache is correct. | |
4832 | ||
4833 | Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for | |
4834 | the device name, using the blkid library. (Addresses Debian bugs | |
4835 | #166048, #179671) | |
4836 | ||
4837 | Fsck now supports backslash escapes in /etc/fstab so that \040 can be | |
4838 | used for spaces in device labels. | |
4839 | ||
4840 | Removed 32-bit limitations for debugfs's dump command. | |
4841 | ||
4842 | If the user specifies a large number of inodes, Mke2fs will | |
4843 | automatically adjust the number of blocks per group to find a valid | |
4844 | set of filesystem parameters. | |
4845 | ||
4846 | Add workaround to detect broken MD devices where when some of the | |
4847 | underlying devices are marked read-only, writes to the MD device are | |
4848 | silently dropped. E2fsck will detect if there is an attempt to run | |
4849 | the journal twice, and abort with an error if this is the case. | |
4850 | (Addresses IBM Bugzilla bug #1226) | |
4851 | ||
4852 | E2fsck will print an error if more than one of the -p/-a, -n or -y | |
4853 | options are specified. | |
4854 | ||
4855 | E2fsck will fix HTREE corruptions in preen mode, without stopping the | |
4856 | boot process. This is needed because the 2.4 ext2 filesystem | |
4857 | accidentally had the INDEX_FL backwards compatibility code removed. | |
4858 | ||
4859 | Mke2fs no longer creates filesystems with the dir_index flag set by | |
4860 | default; the user has to specifically request it. | |
4861 | ||
4862 | Update and clarified various man pages. (Addresses Debian bugs | |
ba142c1b | 4863 | #173612, #175233, #175113, and #170497, #185945, #188318) |
3809bf1d | 4864 | |
508d7f3c TT |
4865 | Created man page for the mk_cmds program (from the libss library). |
4866 | ||
3809bf1d TT |
4867 | Programmer's notes: |
4868 | ------------------- | |
4869 | ||
4870 | Fix various gcc -Wall nits. | |
4871 | ||
4872 | Fixed a lot of portability problems that caused e2fsprogs not to build | |
e5dced7f TT |
4873 | successfully under Solaris and Apple/Darwin. |
4874 | ||
4875 | Fixed a Makefile dependency to allow building e2fsprogs using parallel | |
4876 | make jobs. | |
3809bf1d TT |
4877 | |
4878 | Changes to create a subset distribution which consists only of the | |
4879 | et, ss, uuid, and blkid libraries. The configure script and top-level | |
4880 | makefile were changed to support working with a subset distribution. | |
4881 | ||
ba142c1b TT |
4882 | Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not |
4883 | actually used, and might people who are looking for | |
4884 | EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use. | |
4885 | ||
508d7f3c TT |
4886 | Updated debian files to fix a number of Lintian warnings. |
4887 | ||
4888 | Updated config.guess and config.sub with newer versions from the FSF. | |
3809bf1d | 4889 | |
71df0dc3 TT |
4890 | Removed unnecessary libraries from being linked into the fsck, lsattr, |
4891 | chattr, and blkid executables. | |
4892 | ||
38513011 TT |
4893 | E2fsprogs 1.32 (Nomvember 9, 2002) |
4894 | ================================== | |
4895 | ||
4896 | Fixed a bug in the Unix I/O routines which caused needless writebacks | |
4897 | of clean blocks from the unix_io cache (they were erroneously marked | |
4898 | as being dirty, so they were getting written back to disk before | |
4899 | getting evicted from the disk cache). This was harmless, but it | |
4900 | significantly slowed down e2fsck. | |
4901 | ||
4902 | Made some other minor optimizations to the Unix I/O routines to save a | |
4903 | small amount of CPU time. | |
4904 | ||
4905 | Updated internationalization files. | |
4906 | ||
3809bf1d | 4907 | |
ae65b29f TT |
4908 | E2fsprogs 1.31 (Nomvember 8, 2002) |
4909 | ================================== | |
4910 | ||
4911 | Update EVMS ext2fsim plugin with EVMS 1.2. (We still support | |
4912 | compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error | |
4913 | handling for child process that die unexpectly. Add a hack to force | |
4914 | mkfs to create filesystems that won't cause problems with hardware | |
4915 | that has 2k or 4k minimum blocksize requirements. Read from child | |
4916 | processes in non-blocking mode, so that the GUI continues to update. | |
4917 | ||
4918 | Fix e2fsck so that it returns the appropriate exit code when the root | |
4919 | filesystem has been changed, so that system's rc scripts will be told that | |
4920 | the system needs to be rebooted. | |
4921 | ||
4922 | Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag | |
4923 | was set, some of the descriptor blocks that should have been written | |
4924 | out were getting skipped. | |
4925 | ||
4926 | Changed e2fsck to force out changes to the backup copies of the | |
4927 | superblock and block group descriptors when important changes are made | |
4928 | to those data structures. | |
4929 | ||
4930 | Fix a bug where e2fsck could erroneously mark a filesystem as being | |
4931 | clean if a check of dirty filesystem is interrupted with a ^C. (Bug | |
4932 | introduced in e2fsprogs 1.28.) | |
4933 | ||
4934 | If journal debuging is enabled using --enable-jbd-debug, the debugging | |
4935 | level is now set via the E2FSCK_JBD_DEBUG environment variable. | |
4936 | ||
4937 | If byteswapping support is disabled using configure --disable-swapfs, | |
4938 | skip the tests which depend on byte-swapping, so that "make check" | |
4939 | won't bomb out. | |
4940 | ||
4941 | Lshattr will now display the indexed directory flag. Also, some of | |
4942 | the more esoteric compression flags are supressed unless compression | |
4943 | support has been enabled. | |
4944 | ||
4945 | Update man pages. | |
4946 | ||
4947 | ||
5d823a47 TT |
4948 | E2fsprogs 1.30 (October 31, 2002) |
4949 | ================================= | |
4950 | ||
4951 | When resizing a filesystem, and inodes need to moved, resize2fs will | |
4952 | update the inode's ctime field, and the mtime field of the containing | |
4953 | directories, so that incremental backups using dump/restore will work | |
4954 | correctly. | |
4955 | ||
4956 | In order to avoid spurious errors, e2fsck wil check the last | |
4957 | superblock write time to determine whether or not it can safely use | |
4958 | the LOW_DTIME checks to determine if there are inodes on the orphan | |
4959 | inode linked list that had somehow gotten disconnected. (Addresses | |
4960 | Sourceforge bug #620980) | |
4961 | ||
4962 | Partition in /proc/partitions that being with the string "lvm" are | |
4963 | considered real partitions even if they do not end with a number. | |
4964 | ||
4965 | Fixed a bug in the the uuid generation function, where if /dev/urandom | |
4966 | is not present, but /dev/random is, and there isn't sufficient | |
4967 | entropy, the get_random_byte function could spin a loop forever. | |
4968 | ||
4969 | E2fsck, mke2fs, etc. will now reliably notice when image files are | |
4970 | mounted using the loopback interface. (Addresses Sourceforge bug | |
4971 | #619119) | |
4972 | ||
4973 | When flushing buffers (as is done by badblocks, for example) check to | |
4974 | see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the | |
4975 | FDFLUSH ioctl which causes the MD device driver which causes confusing | |
4976 | syslog messages about obselete ioctl messages. (Addresses Sourceforge | |
4977 | bug #545832). | |
4978 | ||
4979 | Debugfs's write command now checks to see if the destination filename | |
4980 | exists before creating it. (Addresses Sourceforge bug #478195.) | |
4981 | ||
4982 | When installing man pages, search for compressed man pages using all | |
4983 | commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.) | |
4984 | ||
4985 | Fixed a bug in fsck where multiple filesystems specified on the | |
4986 | command were not being checked in parallel due to a logic bug | |
4987 | introduced to support the FSCK_MAX_INST environment variable. | |
4988 | ||
4989 | We have added a new superblock field, s_mkfs_time, which indicates | |
4990 | when a filesystem was created. It is set via mke2fs, and printed out | |
4991 | by dumpe2fs, but is not actually touched by the kernel. | |
4992 | ||
4993 | Dumpe2fs has been made more robust by not aborting if there is an | |
4994 | error reading the block/inode bitmaps; instead it will still print out | |
4995 | the location of the block/inode bitmaps and inode table. | |
4996 | ||
4997 | Add support for the an alternative block group descriptor layout which | |
4998 | allows for on-line resizing without needing to prepare the filesystem | |
4999 | in advance. (This is the incomat feature flag meta_bg.) | |
5000 | ||
5001 | Add support for storing default mount options in the superblock, so | |
5002 | that the filesystem can be mounted with specific mount options without | |
5003 | needing to specify them on the mount command line or in the /etc/fstab | |
5004 | file. | |
5005 | ||
5006 | Add support for a new inode flag, which is to be used for indicating | |
5007 | the top of directory hierarchies for the Orlov block allocator. | |
5008 | ||
5009 | Fix e2fsck so that if it creates the lost+found directory, it does so | |
5010 | with the more apporpriate permissions of 0700. Also change | |
5011 | mklost+found so that it also creates the directory 0700. | |
5012 | ||
5013 | Fixed format bug in e2fsck if NLS is in use. | |
5014 | ||
5015 | Add a German translation for e2fsprogs's NLS support. | |
5016 | ||
5017 | Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at | |
5018 | the beginning of the inode table. This won't matter much, since if | |
5019 | there is a bad block at the beginning of the inode table, the root | |
5020 | directory won't be available. But at least e2fsck won't crash in this | |
5021 | case. | |
5022 | ||
5023 | Fixed endian problems in the htree code for e2fsck and debugfs. | |
5024 | ||
5025 | When byte-swapping a filesystem on a PPC architecture, byte-swap the | |
5026 | bitmaps since the historical big-endian ext2 variant had byte-swapped | |
5027 | bitmaps, and the ext2fs library assumes this. This fixes the | |
5028 | regression test suite on PPC machines. | |
5029 | ||
5030 | Fix e2image so that it handles a bad block in the inode table | |
5031 | appropriately. | |
d5e7810e TT |
5032 | |
5033 | E2fsck now uses a more sophisticated algorithm to salvage corrupted | |
5034 | directories that recovers more information in the corrupted directory | |
5035 | block. | |
5036 | ||
5037 | E2fsck now performs additional consistency checks on indexed (HTREE) | |
5038 | directories. | |
5039 | ||
5040 | Fix bug where efsck might get confused about whether a completely | |
5041 | empty directory block is an empty leaf block or an interior htree | |
5042 | node. This could cause e2fsck to get confused into think that a valid | |
5043 | indexed directory was corrupted. | |
5044 | ||
5045 | E2fsck no longer creates an empty directory entry at the end of a | |
5046 | directory block when optimizing a directory. This would cause some | |
5047 | earlier versions of the dxdir kernel code to corrupt the directory | |
5048 | when attempting to split a node containing an empty directory entry. | |
5049 | ||
5050 | E2fsck could sometimes in rare circumstances leave the indexed flag | |
5051 | set after a small directory was optimized by compressing it instead of | |
5052 | indexing it. (This should never happen in real life, since | |
5053 | directories that small wouldn't have been indexed, but better safe | |
5054 | than sorry.) | |
5055 | ||
5056 | E2fsck now only updates the master superblock in all cases. This | |
5057 | slightly shortens its run time. | |
5058 | ||
5059 | Ext2ed can deal with directory entries of length 0; previously it | |
5060 | would get stuck in an infinite loop. | |
5061 | ||
5062 | Fsck now has support for reiserfs volumes when parsing LABEL= and UUID= | |
5063 | specifiers. (Sourceforge patch #613447) | |
5064 | ||
5065 | Badblocks will now work correctly on read-only devices such as | |
5066 | CD-ROM's. (Sourceforge patch #600451) | |
5067 | ||
5d823a47 | 5068 | Updated and clarified man pages. (Addresses Debian bug #167108) |

c6633059 TT |
5071 | E2fsprogs 1.29 (September 24, 2002) |
5072 | =================================== | |
5073 | ||
5074 | Fixed a bug in e2fsck which could corrupt a directory when optimizing | |
5075 | it (via the -D option) or rebuiliding the hash tree index with a 1 in | |
5076 | 512 probability, due to a fence post error. | |
5077 | ||
5078 | Fixed a bug in the LVM support code which caused LABEL='xxx' not to | |
5079 | work correctly. | |
5080 | ||
5081 | Mke2fs now enables the directory indexing flag by default. (Since | |
5082 | this is a compatible feature flag, it's safe to do so.) | |
5083 | ||
5084 | Tune2fs will support setting the directory indexing feature flag. It | |
5085 | will automatically set up the default hash algorithm and hash seed | |
5086 | fields in the superblock. | |
5087 | ||
5088 | If the bone-headed user enters the root filesystem twice in | |
5089 | /etc/fstab, the -R option which skips the root filesystem will skip | |
5090 | all of them. (Addresses Debian bug #159423). Note! This is not a | |
5091 | precedent for dealing intelligently with any other kind of doubled | |
5092 | entry in /etc/fstab! | |
5093 | ||
5094 | ||
5095 | Programmer's notes: | |
5096 | ------------------- | |
5097 | ||
5098 | Removed perror declaration in lib/et/internal.h. All modern systems | |
5099 | can be expected to define perror() these days. Besides, the lib/et | |
5100 | code wasn't using perror at all anyway. :-) | |
5101 | ||
5102 | ||
b7bad615 TT |
5103 | E2fsprogs 1.28 (August 31, 2002) |
5104 | ================================ | |
5105 | ||
5106 | Add support for the Hashed-Tree Directory Indexing to e2fsck. Support | |
5107 | for setting the htree flag is not included yet, although it can be | |
5108 | manually turned on via the debugfs program. | |
5109 | ||
5110 | Clarified e2fsck error message which is printed when it cannot find | |
5111 | sufficient contiguous block when relcating filesystem metadata. | |
5112 | ||
5113 | Added support for building an EVMS plugin module for ext2/3. This | |
5114 | module is substantially the same as the EVMS module shipping with EVMS | |
5115 | 1.1, with one or two bugfixes. E2fsprogs can also build this plugin | |
5116 | for use with EVMS 1.0 (which did not include the ext2 plugin module), | |
5117 | if the configure --enable-old-evms flag is given. | |
5118 | ||
5119 | Fsck will search through EVMS volumes when trying to resolve | |
5120 | filesystem specifications such as LABEL=xxx or UUID=xxx. | |
5121 | ||
5122 | Added a new utility program, /sbin/findfs, which will return | |
5123 | filesystem specifications such as LABEL=xxx or UUID=xxx, and prints | |
5124 | the device name. | |
5125 | ||
5126 | Update and clarified various man pages. (addresses Debian Bug #145044, | |
5127 | #146437, #131350, #151990, #144621, #141938) | |
5128 | ||
5129 | If there are no filesystems specified on fsck's command line, fsck now | |
5130 | treat that as if the -As options were given. Previously it would | |
5131 | simply do nothing. (Addresses Debian Bug #153102) | |
5132 | ||
5133 | Mke2fs no longer treats a failure to be able to clear the MD signature | |
5134 | at the end of the filesystem as a fatal error. (Addresses Debian Bug | |
5135 | #155007) | |
5136 | ||
5137 | The e2p library functions (which are used by lsattr and chattr) now | |
5138 | double check to make sure the file is a regular file or directory | |
5139 | before attempting to use the ext2 ioctls. Some device drivers | |
5140 | unfortunately respond to the ext2 ioctl's with unknown behaviour. | |
5141 | (Addresses Debian Bug #152029). | |
5142 | ||
5143 | The extended attribute handling has been updated to correspond with | |
5144 | the latest V2 bestbits ACL code. | |
5145 | ||
5146 | Fixed bug in e2fsck which caused it to not clear the dtime field when | |
5147 | processing truncated inodes on the orphan list. This could cause data | |
5148 | loss(!) if a filesystem is rebooted before a truncate has been | |
5149 | committed. | |
5150 | ||
5151 | E2fsck now uses red/black trees in pass1b, which removes some O(n**2) | |
5152 | algorithms. This makes e2fsck much faster in the case of severely | |
5153 | corrupted filesystems where a large number of blocks are claimed by a | |
5154 | large number of inodes. (Thanks to the 2.5 IDE device driver for | |
5155 | inspiring this work.) | |
5156 | ||
5157 | Resize2fs has been significantly sped up when shrinking and expanding | |
5158 | a filesystem by a very small number of blocks (for example, when EVMS | |
5159 | is converting a partition to be an EVMS legacy volume). | |
5160 | ||
5161 | Added a new option to e2fsck, -D, which will optimize or compress all | |
5162 | of the directories in the filesystem. | |
5163 | ||
5164 | E2fsck now catches SIGINT and SIGTERM to make sure it will can | |
5165 | properly clean up and only exit at safe points. Fsck will pass | |
5166 | SIGINT/SIGTERM to its child processes, and wait until they have all | |
5167 | exited before it exits. | |
5168 | ||
5169 | The uuid parsing code in the uuid library now properly complains when | |
5170 | an illegally formated uuid is presented to it. (Addresses Debian bug | |
5171 | #152891) | |
5172 | ||
5173 | Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 | |
5174 | and 2.4.17, since the workaround can cause problems when using a 2.4 | |
5175 | kernel with an old version of glibc built with the 2.2 headers. | |
5176 | ||
5177 | Fixed a bug in mke2fs where it wasn't properly clearing the initial | |
5178 | superblock used by other filesystems. (Addresses Debian bug #147256.) | |
5179 | ||
5180 | Added support for the synchronous directory feature written by Andrew | |
5181 | Morton. | |
5182 | ||
5183 | The debugfs program can delete directories using the rmdir command. | |
5184 | ||
5185 | Add support for 8k and 16k filesystems (for systems with page sizes | |
5186 | that are greater or equal to 8k or 16k, respectively). Note that | |
5187 | these filesystems can not be mounted on x86 systems, or other systems | |
5188 | with only 4k page sizes, due to limitations in the current Linux VM | |
5189 | code. | |
5190 | ||
5191 | Resize2fs requires that the filesystem state be valid and have no | |
5192 | errors; otherwise, e2fsck -f must be run first. (Previously it simply | |
5193 | required that the last fsck time be greater than the last mount time.) | |
5194 | ||
5195 | Configure now defaults the man pages directory to /usr/share/man on | |
5196 | Linux systems. | |
5197 | ||
5198 | E2fsck now offers to truncate inodes which contain too many blocks (so | |
5199 | that i_blocks would overflow. Also fixed handling of large sparse | |
5200 | files. | |
5201 | ||
5202 | E2fsck now more completely checks for symlink validity, including | |
5203 | requiring NULL termination and length checks. | |
5204 | ||
5205 | E2fsck will offer to try forcing a disk write to remap a bad block | |
5206 | after finding a read error when reading a filesystem metadata block. | |
5207 | ||
5208 | Fixed a bug in debugfs which caused the -b and -s options to crash | |
5209 | debugfs, as well as breaking the testb, setb, and clearb functions. | |
5210 | ||
5211 | Added a bmap command to debugfs which calculates the logical to | |
5212 | physical block mapping for a particular inode. | |
5213 | ||
5214 | Fixed a bug in code which checked to see if a device was mounted which | |
5215 | sometimes (rarely) failed in the case of a plain file. | |
5216 | ||
5217 | Fixed a bug in resize2fs where when it reported an error, it would | |
5218 | print a message erroneously indicating that the filesystem had been | |
5219 | resized before it aborted. | |
5220 | ||
5221 | When resizing a plain file which is smaller than the requested size, | |
5222 | resize2fs will attempt to extended the file so that programs like | |
5223 | e2fsck will not complain that the file is too small. | |
5224 | ||
5225 | Resize2fs will print the actual new size of the filesystem when it is | |
5226 | finished resizing. | |
5227 | ||
5228 | Fixed a bug in debugfs where "ls -l" would report incorrectl file type | |
5229 | information on big-endian systems. | |
5230 | ||
5231 | ||
5232 | Programmer's notes: | |
5233 | ------------------- | |
5234 | ||
5235 | Fixed collisions with C++ reserved words. | |
5236 | ||
5237 | Added portability fixes for building e2fsprogs on the HURD and AIX. | |
5238 | ||
5239 | Added the ext2ed program for creation of test cases. (ext2ed has many | |
5240 | limitations and bugs which make it unsuitable for production use.) | |
5241 | ||
5242 | The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new | |
5243 | flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the | |
5244 | name_len field is byte swampped on big-endian machines, since in the | |
5245 | V2 structure, name_len is a char field which is doesn't need to be | |
5246 | byte swapped --- except if an old-style kernel had byte-swapped the | |
5247 | name_len field as part of the V1 structure. | |
5248 | ||

5250 | E2fsprogs 1.27 (March 8, 2002) |
5251 | ============================== | |
5252 | ||
5253 | The warning messages for mke2fs now go to standard error. | |
5254 | ||
5255 | Fixed to make sure "make check" runs all of the test programs with | |
5256 | LD_LIBRARY_PATH set, so that we test the libraries in the build tree. | |
5257 | ||
5258 | The mke2fs program checks the boot sector for the BSD disk label, and | |
5259 | avoids erasing it if it is there. | |
5260 | ||
5261 | Fixed a bug in e2fsck which caused it to core dump if the journal | |
5262 | inode was missing when it was supposed to be there. | |
5263 | ||
5264 | E2fsck now prints ranges in pass 5 when printing deltas for the block | |
5265 | and inode bitmaps. | |
afa14ba0 TT |
5266 | |
5267 | Debugfs's "ls -l" command now will print out the file type information | |
5268 | in the directory entry. | |
5269 | ||
5270 | Create man pages and hard links for fsck.ext3 and mkfs.ext3. If | |
5271 | mke2fs is invoked as mkfs.ext3, create the filesystem with a journal. | |
5272 | ||
5273 | Debugfs can now examine the experimental directory indexing | |
5274 | information. | |
5275 | ||
a471ac52 TT |
5276 | Fixed bug in debugfs which caused it to core dump if modify_inode is |
5277 | called without an open filesystem. | |
5278 | ||
5279 | The debugfs lsdel command now runs its output through a pager first. | |
5280 | ||
afa14ba0 TT |
5281 | When installing manual pages, remove the compressed manual pages first. |
5282 | ||
5283 | Synchronized with Debian's packaging information for e2fsprogs-1.26-1. | |
5284 | ||
5285 | Fix the 2.4 resource limitation workaround introduced in 1.26 which | |
5286 | actually broke things on mips32, sparc32, and Alpha platforms. | |
5287 | ||
a471ac52 TT |
5288 | Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made |
5289 | (which is required by the newer libintl libraries). | |
5290 | ||
afa14ba0 TT |
5291 | Programmer's notes: |
5292 | ------------------- | |
5293 | ||
a8e77249 TT |
5294 | Fixed various gcc -Wall complaints. |
5295 | ||
afa14ba0 TT |
5296 | Fixed a few memory leaks in the e2fsck journaling code, and in the |
5297 | ismounted code checking for a swap device. | |
5298 | ||
5299 | Add new inode I/O abstraction interface which exports an inode as | |
5300 | an I/O object. | |
5301 | ||
5302 | Exported ext2_file_flush as a public interface. | |
5303 | ||
5304 | In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer. | |
5305 | ||
5306 | Lots of small random portability fixes to make e2fsprogs build under | |
5307 | AIX --- even without the 5L compatibility toolkit, and even using the | |
5308 | uber-crippled AIX native C compiler. | |
5309 | ||

0698739a | 5311 | E2fsprogs 1.26 (February 3, 2002) |
a5f3f5c1 | 5312 | ================================= |
cd1a79a5 | 5313 | |
446314fc TT |
5314 | Dumpe2fs will keep going now if the bad block inode can't be read. |
5315 | (Previously it stopped with a fatal error.) | |
5316 | ||
5317 | E2fsck will now give an opportunity to run the journal even if the | |
5318 | recovery flag is not set. This is the default behaviour if e2fsck is | |
5319 | using a backup superblock, since the needs_recovery flag will never be | |
5320 | set in the backup superblock copies. | |
5321 | ||
5322 | E2fsck now automatically finds the backup superblock/group descriptors | |
5323 | even when the primary superblock is completely destroyed for 2k and 4k | |
5324 | filesystems. (Previously it just guessed/assumed that we were dealing | |
5325 | with a 1k filesystem in that case, and users had to manually specify | |
5326 | the backup superblock number.) | |
5327 | ||
5328 | Fixed a bug in e2fsck where it dereferences a null pointer when there | |
5329 | is a problem opening a filesystem in preen mode. | |
5330 | ||
5331 | E2fsck now handles external journals correctly; previously it trashed | |
5332 | the external journal device if the journal needed to be replayed. | |
5333 | ||
5334 | Work around ulimit incompatibility problem caused by recent 2.4 | |
5335 | kernels; the unix IO module will automatically try to set any resource | |
5336 | limits to be infinite on startup. | |
5337 | ||
cd1a79a5 TT |
5338 | Fixed a bug in e2fsck where it wasn't allocating a new block or inode |
5339 | bitmap if it wasn't present and the blocksize was 2k or 4k. | |
9c7ec178 | 5340 | (Addresses Debian Bug #116975) |
cd1a79a5 TT |
5341 | |
5342 | E2fsck will check and fix botched ext3 V1 to V2 superblock updates by | |
5343 | clearing the new V2 fields if they do not make sense or if the ext3 | |
5344 | superblock is version 1 superblock. | |
5345 | ||
5346 | E2fsck will automatically relocate the ext3 journal from a visible | |
5347 | file (i.e., /.journal) to an hidden inode if the filesystem has been | |
5348 | opened read/write. This allows the users to add a journal while the | |
5349 | filesystem is mounted, but the next time the system is rebooted, the | |
5350 | journal file will disappear. This avoids problems with backups, | |
5351 | stupid operators with superuser bits, etc. | |
5352 | ||
5353 | Fix a bug in fsck where it would not support a filesystem type of | |
5354 | "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. | |
5355 | ||
a5f3f5c1 TT |
5356 | Fsck now supports fstab entries of the form "ext3,ext2". It will also |
5357 | automatically identify reiserfs filesystems. | |
5358 | ||
5359 | The number of processes spawned by fsck can now be limited using the | |
5360 | FSCK_MAX_INST environment variable. | |
5361 | ||
446314fc TT |
5362 | Fsck now searchs the LVM proc hierarchy to find logical volumes which |
5363 | should be searched for UUID and label information. | |
5364 | ||
cd1a79a5 TT |
5365 | Work around a bug in 2.4.10+ kernels by trying to unset the filesize |
5366 | limit if at all possible, when opening a block device. (The filesize | |
5367 | limit shouldn't be applied against writes to a block device.) | |
5368 | ||
446314fc TT |
5369 | In mke2fs and e2fsck, specifying the -c option twice will now do |
5370 | a read/write test on the disk. Update the man pages to encourage | |
5371 | using the -c option, and to discouraging running badblocks separately, | |
5372 | since users tend to forget to set the blocksize when running | |
5373 | badblocks. | |
5374 | ||
cd1a79a5 TT |
5375 | Mke2fs now automatically clears the immutable attribute on a |
5376 | pre-existing .journal file left over from a previous failed attempt to | |
5377 | add a journal to an alreadyy-mounted filesystem. | |
5378 | ||
5379 | Fixed mke2fs's exit codes to consistently indicate when the mke2fs | |
5380 | operation failed. | |
5381 | ||
446314fc TT |
5382 | Mke2fs now creates the lost+found directory with permissions of 0700, |
5383 | so that files that had previously lived in protected directory are | |
5384 | safe if they get dropped in lost+found and the system administrator | |
5385 | doesn't deal with immediately. (Addresses Debian #bug 118443) | |
5386 | ||
5387 | Mke2fs and e2fsck (and all programs that use the | |
5388 | ext2fs_check_if_mounted function) will now properly identify that a | |
5389 | device is mounted, even in cases where devfs has confused things with | |
5390 | multiple devices names with the same identity, or if a dim-witted | |
5391 | system administrator has done something stupid like creating device | |
5392 | file aliases in their home directory. Also now checks for swap devices | |
5393 | by using /proc/swaps. (Addresses Debian bug #106622) | |
5394 | ||
a5f3f5c1 TT |
5395 | Added a new option (-T) to tune2fs which sets the time a filesystem |
5396 | was last checked. | |
5397 | ||
cd1a79a5 TT |
5398 | Speed up e2image when creating sparse raw image files by optimizing |
5399 | away excess lseek() system calls. | |
5400 | ||
5401 | Fix support of large (> 2GB) files when used as a filesystem in | |
5402 | mke2fs, tune2fs, debugfs, and findsuper. | |
5403 | ||
5404 | Debugfs's stat and icheck commands now properly deals with large (> | |
5405 | 2GB) files. | |
5406 | ||
5407 | Debugfs's set_super_value command now prints out the list of valid | |
5408 | superblock fields which can be set using the command. | |
5409 | ||
446314fc TT |
5410 | Debugfs's rm and kill_file command now updates the superblock free block |
5411 | and inode counts, thus keeping the filesystem consistent. | |
5412 | ||
a5f3f5c1 TT |
5413 | Debugfs's lsdel command now takes an optional argument which allows |
5414 | the user to only see the most recently deleted files. | |
5415 | ||
5416 | A new command (undel) was added to debugfs which automates | |
5417 | undeleting a deleted inode and linking it back to a directory. | |
5418 | ||
5419 | Debugfs's ls command now takes a new option, -d, which lists | |
5420 | deleted directory entries. | |
5421 | ||
5422 | Debugfs's testb, freeb, setb, and find_free_block commands now take an | |
5423 | optional count argument. | |
5424 | ||
cd1a79a5 TT |
5425 | Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will |
5426 | be used to signal that a particular inode should not be eligible for | |
5427 | tail-merging --- this is needed for programs like LILO. | |
5428 | ||
5429 | The findsuper (an unreleased, uninstalled utility program) has been | |
5430 | improved to add extra validity checks and to add a progress meter. | |
5431 | (It is still an unsupported program; the officially supported way to | |
5432 | recover from a trashed partition table is to use gpart; findsuper is | |
5433 | for wizards only. :-) | |
5434 | ||
5435 | Debugfs was fixed to compile with "configure --disable-swapfs". | |
5436 | ||
446314fc | 5437 | Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) |
cd1a79a5 TT |
5438 | |
5439 | Added new translation file for Turkish. | |
5440 | ||
446314fc TT |
5441 | Programmer's notes: |
5442 | ------------------- | |
5443 | ||
5444 | Fix general gcc -Wall complaints. | |
5445 | ||
5446 | E2fsprogs (mostly) works with the dietlibc. | |
5447 | ||
5448 | The programming texinfo file has been expanded to include description | |
5449 | of additional libext2fs functions. (Still not compeltely done, but a | |
5450 | lot of the more important functions have been documented.) | |
5451 | ||
5452 | Added a umask structure to struct_ext2_filsys, which currently only | |
5453 | modifies the behaviour of ext2fs_mkdir(), but if we add any file | |
5454 | creation functions to libext2fs, we should also make sure they respect | |
5455 | the umask setting. | |
5456 | ||
a5f3f5c1 TT |
5457 | The build-rpm script was fixed to be a bit more safe. |
5458 | ||
5459 | The tests' Makefile now has a way of automating test case creation | |
5460 | for e2fsck, using "make testnew". | |
5461 | ||
5462 | Created a new function, ext2fs_dir_iterate2 which passes more | |
5463 | information to the callback function (identical to the one used by | |
5464 | ext2fs_dblist_dir_iterate). The directory iterator functions take a | |
5465 | new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted | |
5466 | directory entries. If the directory entry is deleted, the callback | |
5467 | function will be called with the entry paraemter set to | |
5468 | DIRENT_DELETED_FILE. | |
5469 | ||
5470 | Added new functions, ext2fs_inode_alloc_stats and | |
5471 | ext2fs_block_alloc_stats, which takes updates block/inode allocation | |
5472 | statistics in the bitmaps, block group descriptors, and superblock | |
5473 | when inodes or blocks are allocated or deallocated. | |

5476 | E2fsprogs 1.25 (September 20, 2001) |
5477 | =================================== | |
5478 | ||
5479 | This is primarily a bug-fix release; no new features were added, but | |
5480 | there are a number of embarassing bug fixes and cleanups applied. | |
5481 | ||
5482 | Fix a bug mke2fs which causes stack garbage to be written to disk when | |
5483 | zapping disk sectors. (This bug could cause mke2fs to core dump for | |
5484 | some kernels, I suspect with security enhancement patches.) | |
5485 | ||
5486 | Remove unneeded #include of <linux/config.h> which was breaking | |
5487 | building e2fsprogs on the Hurd. (Addresses Debian bug #112414.) | |
5488 | ||
5489 | Updated tune2fs man page to reflect the fact that adding or removing a | |
5490 | journal doesn't require running e2fsck. | |
5491 | ||
5492 | Remove use of AC_REQUIRE from autoconf which had been used to prevent | |
5493 | AC_CANONICAL_HOST from being called twice; unfortunately this causes | |
5494 | recent autoconf to bomb out since they don't allow AC_REQUIRE to be | |
5495 | used outside of autoconf macros. Fortunately, it doesn't seem to be | |
5496 | necessary any more, anyway. | |
5497 | ||
5498 | E2fsck will now not fall back to an alternate superblock if the user | |
5499 | specifies the superblock location explicitly on the command-line. | |
5500 | This allows easier recovery from a situation where the primary | |
5501 | superblock and block groups are slightly corrupted, but the backup | |
5502 | superblocks are completely broken. | |
5503 | ||
5504 | Fix problem which caused compile_et and mk_cmds to blow up if | |
5505 | e2fsprogs was in a directory with a pathname that contained spaces. | |
5506 | ||
5507 | We are now more paranoid about checking the entry in /etc/mtab to make | |
5508 | sure the filesystem is really mounted, since some broken distributions | |
5509 | (read: Slackware) don't initialize /etc/mtab before checking non-root | |
5510 | filesystems. (Slackware also doesn't check the root filesystem | |
5511 | separately, and reboot if the root filesystem had changes applied to | |
5512 | it, which is dangerous and broken, but there's nothing I can do about | |
5513 | that.) | |
5514 | ||
5515 | Make UUID library C++ friendly by adding appropriate extern "C" | |
5516 | declarations and using const in the function declarations. | |
5517 | ||
5518 | Fix up the com_err texinfo file so that it can product a valid info | |
5519 | file (previously, it could only be used to generate paper | |
5520 | documentation using texinfo.tex). | |
5521 | ||
5522 | ||
fb70775b TT |
5523 | E2fsprogs 1.24a (September 2, 2001) |
5524 | =================================== | |
5525 | ||
5526 | Fix brown-paper bug in mke2fs which caused it to segfault when | |
5527 | printing the version string. | |
5528 | ||
5529 | ||
109624a1 TT |
5530 | E2fsprogs 1.24 (August 30, 2001) |
5531 | ================================ | |
5532 | ||
5533 | Revert the BLKGETSIZE64 support, since for some distributions, this | |
5534 | ioctl has been used by an unofficial kernel patch to update the last | |
5535 | sector on the disk, and this was causing disk corruption problems as a | |
5536 | result. | |
5537 | ||
5538 | Mke2fs is now more careful about zapping swap space signatures and | |
5539 | other filesystem/raid superblock magic values so that programs like | |
5540 | mount who try to use hueristics to determine the filesystem type of a | |
5541 | partition are less likely to be confused. | |
5542 | ||
5543 | E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a | |
5544 | regular file (since Andreas Dilger's on-line resizing tools will set | |
5545 | its mode bits). | |
5546 | ||
5547 | Fixed some minor texinfo, man pages nits for spelling errors, | |
5548 | texinfo warnings, etc. (Addresses Debian bug #110621.) | |
5549 | ||
5550 | E2fsprogs program no longer print the filesystem version number | |
5551 | (i.e. 0.5b), since it only confuses people and doesn't serve any real | |
5552 | purpose. | |
5553 | ||
5554 | E2fsck will once again compile under libc5, since it will supply its | |
5555 | own version of strnlen if necesssary. | |
5556 | ||
5557 | mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers | |
5558 | when specifying the external journal device. tune2fs will also search | |
5559 | devices looking for the externla journal debice when removing. | |
5560 | ||
5561 | E2fsprogs 1.23 (August 15, 2001) | |
5562 | ================================ | |
d1ef5c34 TT |
5563 | |
5564 | Add initial support for extended attributes (EA); e2fsck will | |
6c0a0417 TT |
5565 | correctly handle a filesystem with EA's and check the EA blocks for |
5566 | corruptions. | |
5567 | ||
d494bba8 TT |
5568 | E2fsck's symlink sanity checking has been cleaned up. It now checks |
5569 | the i_size value of fast symlinks, and checks for immutable flags | |
5570 | being set of symlinks, etc. | |
5571 | ||
c4ac9e14 TT |
5572 | E2fsck now offers to clear inodes which are special files that have a |
5573 | non-zero i_blocks or i_size field. (The i_size field check was in the | |
5574 | previous version of the code, but due to a bug it didn't offer to | |
5575 | clear the inode unless i_size and i_size_high were both non-zero.) | |
5576 | ||
d494bba8 TT |
5577 | E2image can now create "raw" image files, which only contain the |
5578 | filesystem metadata placed in a spare file so that e2fsck, dumpe2fs, | |
5579 | debugfs, etc., can be run directly on the raw image file. | |
bf16d106 TT |
5580 | |
5581 | Add support for the 64-bit block device patches. | |
5582 | ||
5583 | Fixed bugs in creating external journals with a 1k blocksize. | |
5584 | ||
d494bba8 TT |
5585 | Add initial support for external journals (so long as the external |
5586 | journal only supports a single filesystem) in e2fsck. | |
5587 | ||
5588 | Remove requirement for needing to run fsck on a filesystem after | |
5589 | removing a journal (either internal or external). | |
5590 | ||
bf16d106 | 5591 | The man pages now document how to create and manage external journals. |
d1ef5c34 TT |
5592 | |
5593 | Speed up the check of an ext3 filesystems by avoiding a needless flush | |
5594 | of all of the superblock and block group descriptors. | |
5595 | ||
d494bba8 TT |
5596 | Speed up creating an internal journal using tune2fs in the case where |
5597 | the filesystem has a lot blocks already allocated. | |
5598 | ||
c4ac9e14 TT |
5599 | Tune2fs has been fixed to make sure that only error messages go to |
5600 | stderr, and normal message go to stdout. (Addresses Debian bug #108555) | |
5601 | ||
d494bba8 | 5602 | Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will |
c4ac9e14 | 5603 | now not set the sparse_super feature. (Addresses Debian bug #108165) |
d494bba8 | 5604 | |
d1ef5c34 TT |
5605 | Add support in fsck for the filesystem type "auto". |

5607 | Fsck -A will not try to interpret device names for filesystems which |
5608 | have a pass number is 0. (Addresses Debian bug #106696). | |
5609 | ||
5610 | Fsck prints a warning message if now valid filesystems are passed to | |
5611 | it. (Addresses Debian Bug #107458.) | |
5612 | ||

5613 | E2fsck now gives an explicit warning if there filesystem still has |
5614 | errors at the end of the run. (Addresses Debian bug #104502) | |
5615 | ||
d494bba8 | 5616 | E2fsck will set the EXT2_ERROR_FS flag if the journal superblock |
c4ac9e14 TT |
5617 | reflects an error. E2fsck will also not run the orphan list if the |
5618 | filesystem contains errors, since the orphan list might be corrupted. | |
d494bba8 TT |
5619 | |
5620 | E2fsck now prints the number of large files when given the -v option. | |
5621 | ||
5622 | Fixed minor memory leaks in e2fsck. | |
bf16d106 | 5623 | |
c4ac9e14 | 5624 | Some minor man pages updates. (Addresses Debian bug #30833, #108174) |

5627 | E2fsprogs 1.22 (June 22, 2001) |
5628 | ============================== | |
5629 | ||
5630 | Fixed a bug in e2fsck's handling of orphan inodes which are special | |
5631 | files (i.e., block/character device files, named FIFO's, etc.). | |
5632 | ||
5633 | Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused | |
5634 | tune2fs to fail at adding a journal to a mounted filesystem. | |
5635 | ||
5636 | Fixed a few big-endian bugs in e2fsprogs | |
5637 | * The directory block functions were accidentally reporting | |
5638 | some directories as corrupted when they weren't. | |
5639 | * If e2fsprogs is compiled --disable-swapfs, the C language | |
5640 | equivalents weren't being included for big-endian platforms. | |
5641 | (Fixes Debian bug #101686). | |
5642 | ||
5643 | Fixed a Hurd compilation problem. (Addresses Debian bug #101361) | |
5644 | ||
5645 | Programmer's notes: | |
5646 | ------------------- | |
5647 | ||
5648 | Use platform independent method of defining the BLKFLSBUF and FDFLUSH | |
5649 | ioctls, and allow them to be defined for non-i386 platforms. | |
5650 | ||
5651 | The uuid.h header file is now protected against multiple inclusions. | |
5652 | ||
5653 | E2fsprogs is now being developed using BitKeeper. Changed the test | |
5654 | scripts to deal with BK's stripping CR characgters from text files, | |
5655 | and changed the top-level Makefile.in to avoid including BitKeeper | |
5656 | files when generating the source tarball. | |
5657 | ||
5658 | ||
b90b826b TT |
5659 | E2fsprogs 1.21 (June 15, 2001) |
5660 | ============================== | |
5661 | ||
5662 | Added new configure flags which allow a subset e2fsprogs to be built; | |
5663 | this is most useful for boot floopies, since the resulting shared | |
5664 | libraries and programs are slimmed down by removing features that | |
5665 | aren't necessary for a boot floppy. The new flags that were added | |
5666 | are: --disable-swapfs, which removes support for byte swapping old | |
5667 | legacy PPC/68k filesystems, --disable-debugfs, which removes support | |
5668 | for debugfs from the libext2fs library, --disable-imager, which | |
5669 | removes support for the e2image program, and --disable-resizer, which | |
5670 | removes support for resize2fs. | |
5671 | ||
5672 | E2fsck now prints the number of mounts or days elapsed since the last | |
5673 | check when e2fsck is forced to check an otherwise clean filesystem. | |
5674 | ||
5675 | Tune2fs now prints an informative message about how often a filesystem | |
5676 | will be checked when adding a journal to the filesystem, to remind the | |
5677 | user that he/she may want to adjust those parameters using tune2fs | |
5678 | -c/-i. | |
5679 | ||
5680 | Worked around hurd brain-damage which causes e2fsck to sometimes | |
5681 | believe a filesystem is the root filesystem based on device numbers | |
5682 | (since Hurd doesn't have dev_t's, which is arguably a POSIX.1 | |
5683 | violation). | |
5684 | ||
5685 | Fixed a bug introduced in 1.20 which caused e2fsck to abort with an | |
5686 | erroneous error with the -F option was specified. | |
5687 | ||
5688 | Fixed a ext3 recovery bug in the revoke handling; synchronized with | |
c05b5521 TT |
5689 | ext3 0.7a. |
5690 | ||
767de097 TT |
5691 | Fixed two bugs in e2fsck's handling of dup block handling, dealing |
5692 | with relatively uncommon edge cases: a directory with an indirect | |
5693 | block which is claimed by another file, and when the last inode in the | |
5694 | filesystem has blocks claimed by another file. | |
5695 | ||
5a9c036b TT |
5696 | E2fsck now checks to see if the i_size field of a fast symlink is too |
5697 | big, and offers to clear the symlink if so. | |
5698 | ||
5699 | E2fsck now checks to see if i_size_high of special files is non-zero, | |
5700 | and offers to clear i_size_high. | |
5701 | ||
767de097 TT |
5702 | Fix e2fsck's handling of incompatible journal flags so that the user |
5703 | has chance to abort, and then has the option to clear out the journal | |
e333845b | 5704 | entirely. (Addresses Debian bug #98527.) |
767de097 | 5705 | |
b90b826b TT |
5706 | Fixed a bug in fsck which could cause it to core dump if a mix of |
5707 | standard and non-standard device names are used in /etc/fstab. | |
5708 | (Debian bug #100559) | |
5709 | ||
c05b5521 TT |
5710 | Fixed a bug in debugfs which caused read errors when copying a file to |
5711 | not be noticed. | |
5712 | ||
b90b826b TT |
5713 | The debugfs set_super_value command can now modify the s_lastcheck field. |
5714 | ||
c05b5521 TT |
5715 | Fixed a bug in lsattr and chattr which was accidentally introduced in |
5716 | 1.20 to support > 2GB files; both lsattr and chattr wasn't reading | |
5717 | directories correctly because the change modified the layout of struct | |
5718 | dirent to be incompatible with the libe2p shared library. | |
5719 | ||
b90b826b TT |
5720 | Cleaned up the mke2fs manual page and included a discussion about why |
5721 | it's good to periodically check the filesystem even when journaling is | |
5722 | enabled. | |
5723 | ||
767de097 TT |
5724 | Programmer's notes: |
5725 | ------------------- | |
5726 | ||
5727 | Fix general gcc -Wall complaints. | |
5728 | ||
5729 | The types needed by the ext2 header files are now provided by | |
5730 | lib/ext2fs/ext2_types.h, instead of include/asm/types.h. | |
5731 | ||
c05b5521 | 5732 | Integers are now preferred to longs when trying to find a 32-bit type |
b90b826b TT |
5733 | in ext2_types.h. Also, if linux/types.h has already been defined, |
5734 | don't try to redefine the types. | |
c05b5521 | 5735 | |
767de097 TT |
5736 | Fixed make depend script so that it automatically corrects the |
5737 | pathname cleanups performed by make -M, so I don't have to fix them up | |
5738 | by hand. | |
5739 | ||
5740 | Fixed the d_loaddump test case to be more robust, and not depend on | |
5741 | bash'isms. | |
5742 | ||
5743 | Removed debugfs's dependence on pread(), which was accidentally | |
5744 | intrudced in e2fsprogs 1.20 | |
5745 | ||
c05b5521 TT |
5746 | Fixed a performance bug in the libext2fs's icount routine; the size |
5747 | estimate of the icount array was incorrectly being calculated. | |
5748 | ||
b90b826b TT |
5749 | Removed use of the badblocks compatibility functions in the e2fsprogs |
5750 | programs. | |
5751 | ||
5752 | Added paranoia code which protects against strange cases where /etc | |
5753 | isn't on the root filesystem, or if /etc/mtab doesn't exist. | |
5754 | ||
5755 | The header file ext2_types.h is now installed. | |
5756 | ||
5757 | Autoconf is used to determine when we are on big-endian machines, | |
5758 | instead of doing run-time tests, to save a few bytes of code. | |
5759 | ||
5760 | The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap | |
5761 | functions are no longer inline functions, which saves space and | |
5762 | doesn't really cost any real performance. | |
5763 | ||
5764 | The ext2fs library no longer depends on the e2p library. (What need | |
5765 | there was of it --- namely, fsetflags, was coded in-line). | |
5766 | ||
5767 | Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even | |
5768 | when the user is stupid and tries compiling the package using "make | |
5769 | install" as root. | |
5770 | ||
5771 | Miscellaneous code cleanups: | |
5772 | * Added missing files from Makefile.in's SRCS file, so that | |
5773 | their dependencies would be properly calculated. | |
5774 | * Removed redundant code | |
5775 | * Fixed comments in code | |
5776 | * Removed no-longer unneeded argsused #pragma. | |
c05b5521 | 5777 | |
767de097 | 5778 | |
5a009bb9 | 5779 | E2fsprogs 1.20 (May 20, 2001) |
31d1d0c8 | 5780 | ============================= |
5570a65a | 5781 | |
31d1d0c8 TT |
5782 | Add support for replaying the ext3 journal purely in user mode, |
5783 | including handling the orphaned inode list. Used code contributed by | |
5784 | Andreas Dilger, with bug fixes and the orphaned inode handling done | |
5785 | by Theodore Ts'o. | |
5786 | ||
5787 | The mke2fs and tune2fs programs can create or modify a filesystem to | |
5788 | include an ext3 journal. Tune2fs also can be used to remove an ext3 | |
5789 | journal from a filesystem. | |
5570a65a TT |
5790 | |
5791 | E2fsck will now check for the existence of a linked list of orphan | |
5792 | inodes in the superblock, and clear those inodes before starting the | |
5793 | rest of the filesystem check (but after the journal playback). | |
5794 | ||
31d1d0c8 TT |
5795 | E2fsck now validates the file descriptor passed to the -C option, |
5796 | which saves against the completion bar getting written to an | |
5797 | unexpected location, such as the disk being checked. (Debian | |
5798 | bug/wishlist #55220) | |
5799 | ||
5800 | E2fsck will now bump the filesystem revision number from zero to one | |
5801 | if any of the compatibility bits are set. | |
5802 | ||
5803 | Fixed a bug where a badly corrupted directory on a big endian system | |
5804 | could cause e2fsck to die with a bus error. The | |
5805 | ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in | |
5806 | the ext2 library now does alignment sanity checks on the rec_len field | |
5807 | of the directory entry before using it. | |
5808 | ||
5809 | The ext2 library has been enhanced to make tune2fs safe to run on | |
5810 | mounted filesystems. (Users could usually get away with using tune2fs | |
5811 | on mounted filesystems before, but with the advent of ext3 and | |
5812 | journaling, it became important to make tune2fs was *really* safe for | |
5813 | use even when the filesystem being modified is mounted.) E2label is | |
5814 | now implemented by tune2fs using an argv[0] dispatch, so that e2label | |
5815 | is also now safe for use on mounted filesystems. | |
5816 | ||
5817 | Added a new program, e2image, which creates a backup of critical ext2 | |
5818 | filesystem data structures. The generated image file can be examined | |
5819 | using dumpe2fs and debugfs. In the future, e2fsck will be able to use | |
5820 | the image file to help recover very badly damaged filesystems. | |
5821 | ||
5822 | Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files | |
5823 | no longer cause e2fsck to bomb out. Also treat files > 2GB as being | |
5824 | large file when deciding whether or not the filesystem has large files. | |
5825 | ||
5826 | Fixed lsattr and chattr so that they work correctly on large files. | |
5827 | (Fixes Debian bug #72690.) | |
5828 | ||
5829 | Removed limitation in get_device_size() which imposed a one terrabyte | |
5830 | filesystem limitation. (Most 2.2 kernels still have a signed int | |
5831 | problem which cause 1 TB block device limitation. Fortunately, the | |
5832 | kernel patches to fix this are much easier than fixing the 2TB | |
5833 | limitation in the kernel. :-) | |
5834 | ||
5835 | A max_mount_count of zero is now treated as if no mount count were | |
5836 | set. (Previously, no mount count was indicated by using -1, and a | |
5837 | mount count of zero caused e2fsck to always be run.) | |
5838 | ||
77648565 | 5839 | Mke2fs supports two new filesystem types largefile and largefile4. |
31d1d0c8 TT |
5840 | |
5841 | Mke2fs now adds some randomness in s_max_mount_count so that multiple | |
5842 | filesystems won't be all checked at the same time under normal | |
5843 | operations. | |
5844 | ||
5570a65a TT |
5845 | Fixed bug in the progress bar printing code which could cause e2fsck |
5846 | to core dump on an illegal filesystem. | |
5847 | ||
31d1d0c8 TT |
5848 | Fixed bug in fsck which could allow more than one instance of e2fsck |
5849 | to be printing a progress bar. (Debian bug #65267) | |
5850 | ||
5570a65a TT |
5851 | Fsck using a UUID or a LABEL specifier will work even if devfs is |
5852 | compiled into the kernel and not mounted. If the pathnames in | |
5853 | /proc/partitions are incorrect, fsck will search /dev for the correct | |
5854 | device (using the new ext2fs_find_block_device library function). | |
5855 | Fsck now also checks the RAID devices first so that they are properly | |
31d1d0c8 TT |
5856 | found when they are in use. Support has also been added to support |
5857 | additional IDE disks and the DAC 960 device names. (Debian bug #94159) | |
5858 | ||
5859 | Fixed a bug in fsck which caused it not deal properly with 16 | |
5860 | byte long filesystem labels. | |
5570a65a | 5861 | |
5a009bb9 TT |
5862 | Fsck's -t option has been made a lot more flexible. The semantics for |
5863 | what happens if a comma-separated list to fsck has been regularized, | |
5864 | and it is now possible to filter what filesystems will get checked | |
5865 | based what is in the filesystem's fstab entry's option field. (Debian | |
5866 | bug #89483.) | |
5867 | ||
5570a65a TT |
5868 | The dumpe2fs program can now print out the group description |
5869 | information in hex, and also prints the location of the superblock and | |
5870 | block group descriptor for those block groups that have them. | |
5871 | ||
5872 | Mke2fs now clears the ext2 superblock before it starts creating a | |
5873 | filesystem, so that the superblock magic number is only written if the | |
5874 | filesystem creation process successfully completes. | |
5875 | ||
5876 | The debugfs program's stat command now pretty-prints the blocks used | |
5877 | by an inode so that it's more compact and informative. | |
5878 | ||
5879 | The debugfs stats command now uses the same libe2p code (which is used | |
5880 | by dumpe2fs) to print the superblock header information. This is more | |
5881 | complete, and it avoids a bit of code duplication. | |
5882 | ||
5883 | Added a new debugfs command, set_super_value (ssv) which allows the | |
5884 | user to set arbitrary superblock fields. | |
5885 | ||
31d1d0c8 TT |
5886 | Debugfs was extended to support inode numbers in hex (by prefixing |
5887 | them with 0x), and so that modify_inode can set the inode generation | |
5888 | number. Also, there is now a new function command called logdump | |
5889 | which will dump an ext3 journal. | |
5890 | ||
5891 | Fixed a bug in debugfs so that quitting out of the pager doesn't kill | |
5892 | debugfs. | |
5893 | ||
5894 | Debugfs's dump command now stops immediately upon reporting a disk | |
5895 | read error. (Fixed a bug in ext2fs_file_read library routine which | |
5896 | caused debugfs not to stop.) (Debian bug #79163) | |
5897 | ||
5898 | On systems with /proc/mounts (mainly Linux systems), /proc/mounts is | |
5899 | checked before /etc/mtab is used, since /proc/mounts is more likely to | |
5900 | be accurate. | |
5901 | ||
5902 | Added portability fixes for Solaris and Linux/ia64. | |
5903 | ||
5904 | Various manual pages were clarified and cleaned up. (Fixed debian | |
5905 | bugs #63442, #67446, and #87216) | |
5906 | ||
5570a65a TT |
5907 | |
5908 | Programmer's notes: | |
5909 | ------------------- | |
5910 | ||
5911 | The e2fsck message printer now supports %Iu and %Ig, which will print | |
5912 | out the inode's user and group owners, respectively. | |
5913 | ||
31d1d0c8 TT |
5914 | E2fsprogs now includes its own version of include/linux/ext2_fs.h, so |
5915 | that no longer dependent on the system having the correct version of | |
5916 | the kernel header files. | |
5917 | ||
5570a65a TT |
5918 | Added a new function to libext2, ext2fs_find_block_device(), which |
5919 | searches the system (i.e., /dev, /devfs, /devices) for a pathname to a | |
5920 | device given its device number. | |
5921 | ||
31d1d0c8 TT |
5922 | Added a new function to libext2, ext2fs_sync_device, which centralizes |
5923 | all of the places which might try to use the BLKFLSBUF or FDFLUSH | |
5924 | ioctls (and usually failing to define them since the system header | |
5925 | files don't usually do this for us, and we're trying to avoid usage of | |
5926 | kernel include files now). | |
5927 | ||
5570a65a TT |
5928 | Added new utility programs in tests/progs: random_exercise and |
5929 | hold_inode. They aren't built by default; they're useful for | |
5930 | exercising ext3 filesystem code. | |
5931 | ||
31d1d0c8 TT |
5932 | Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes |
5933 | the filesystem close functions to only update the superblock, and to | |
5934 | not touch the block group descriptors. Needed by tune2fs when | |
5935 | modifying a mounted filesystem. | |
5936 | ||
5937 | Got rid of struct ext2fs_sb and replaced it with the standard struct | |
5938 | ext2_super_block from include/linux/ext2_fs.h. Note: this may break | |
5939 | source (but not binary) compatibility of some users of the ext2 | |
5940 | library. Those applications should just simply do a global search and | |
7d614e3d TT |
5941 | replace of struct ext2fs_sb with struct ext2_super_block, and include |
5942 | the new header file <ext2fs/ext2_fs.h> which defines it. | |
31d1d0c8 TT |
5943 | |
5944 | The ino_t type has been renamed ext2_ino_t to protect applications | |
5945 | that attempt to compile -D_FILE_OFFSET_BITS=64, since this | |
5946 | inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an | |
5947 | unexpected ABI change. | |
5948 | ||
5949 | The Makefiles have been reworked so that "make check" can be run from | |
5950 | the top-level Makefile. | |
5951 | ||
5952 | Fix general gcc -Wall complaints and removed dead code. | |
5953 | ||
5954 | Remove use of NOARGS, because we assume everyone does ANSI C these | |
5955 | days. | |
5956 | ||
5957 | Added build-rpm script from sct. | |
5958 | ||
5959 | New functions ext2fs_image_{inode,super,bitmap}_{read,write} added | |
5960 | to support e2image. | |
5961 | ||
5962 | New function ext2fs_flush_icache which must be called if the | |
5963 | application program modifies the inode table blocks without going | |
5964 | through ext2fs_write_inode() interface. | |
5965 | ||
5966 | New ext2fs_check_mount_point() function, which will return the mount | |
5967 | point of a device if mounted. | |
5968 | ||
5969 | The io_channel abstraction now has an optional interface, | |
5970 | io_channel_write_range, which allows specific byte ranges to be | |
5971 | written. | |
5972 | ||
5973 | The unix_io IO channel now supports write-through caching, so that | |
5974 | journal creation is more efficient. | |
5975 | ||
5976 | Added x86 assembly language routines to support byte swapping, to | |
5977 | reduce executable size. | |
5978 | ||
5979 | Fixed bug in the utility program subst so that it's possible to | |
5980 | replace a substitution variable with a zero-length string. | |
5981 | ||
5982 | Fixed numbering e2fsck pass1 problem numbers; an extra zero had | |
5983 | slipped into some of the problem number. | |
5570a65a | 5984 | |
b777e26e TT |
5985 | E2fsprogs 1.19 (July 13, 2000) |
5986 | ============================== | |
ab146766 TT |
5987 | |
5988 | Release the resize2fs program since the timeout before it could | |
006ea71e | 5989 | be released under the GPL has finally expired. |
ab146766 TT |
5990 | |
5991 | Add experimental support needed for the ext2 compression patches. | |
5992 | This requires compiling e2fsprogs with the --enable-compression flag | |
5993 | to the configure script. | |
5994 | ||
5995 | Added ext3 journalling support. E2fsck will run the journal (if | |
5996 | necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is | |
5997 | installed as a symlink to e2fsck. Fsck has been taught about ext3, | |
5998 | and treats it the same as ext2 in terms of the progress bar logic. | |
5999 | Dumpe2fs will display the superblock journaling information if the | |
6000 | filesystem has a journal. The ext2 library will now permit opening an | |
6001 | ext3 filesystem with the recovery flag set. This is necessary for | |
6002 | on-line dump's to work correctly, but there may be issues with this | |
6003 | working well since ext3 is much less agressive about syncing blocks to | |
6004 | the filesystem, since they're safe on the journal. | |
6005 | ||
6006 | Tune2fs and e2fsck have been changed to allow the mount_count check to | |
6007 | be disabled by setting max_mount_count to -1. (This was already | |
6008 | supported by the kernel.) | |
6009 | ||
6010 | Create a symbolic link for fsck.ext3, since the e2fsprogs utilities | |
6011 | are used for ext3 as well. | |
6012 | ||
6013 | Added internationalization support for e2fsprogs; must be enabled | |
6014 | by passing --enable-nls to configure. | |
6015 | ||
6016 | Always use the provided ext2fs header files to insulate ourselves from | |
6017 | kernel version changes. Which include files are used by e2fsprogs | |
6018 | have also been cleaned up to improve portability. | |
6019 | ||
6020 | Limit the number of times that e2fsck updates the progress bar so that | |
6021 | people who are booting using a 9600 baud console don't get swampped by | |
6022 | too many updates. | |
6023 | ||
6024 | Improved the loop detection algorithm in e2sck's pass #3 so that it is | |
6025 | much, much faster for large filesystems with a large number of | |
6026 | directories. | |
6027 | ||
6028 | The memory footprint for e2fsck is now slightly smaller than before. | |
6029 | ||
6030 | E2fsck now checks if special devices have a non-zero size, and offers | |
6031 | to clear the size field if it finds such an inode. | |
6032 | ||
6033 | E2fsck now checks if special devices have the append-only flag set, | |
6034 | and offers to clear the inode. | |
6035 | ||
6036 | E2fsck now properly handles some "should never fail" cases during a | |
6037 | bitmap copy in pass5. | |
6038 | ||
6039 | E2fsck now properly prints control characters in filenames as ^A .. ^Z. | |
6040 | ||
31d1d0c8 TT |
6041 | E2fsck now calculates the correct location of the backup superblock in |
6042 | the case of filesystem blocksizes > 1k. | |
6043 | ||
6044 | Fixed a bug in e2fsck's calculation of the number of inodes_per_block | |
6045 | which normally didn't cause problems under most filesystem parameters, | |
6046 | but could cause a valid superblock to be rejected in extreme cases. | |
6047 | Other checks for validating superblock values were made more | |
6048 | stringent. | |
6049 | ||
ab146766 TT |
6050 | Added non-destructive write testing to the badblocks program, courtesy |
6051 | of David Beattie. The badblocks also now has an option to input the | |
6052 | current set of bad blocks, so that known bad blocks are skipped to | |
6053 | speed up the badblocks test. There is also a persistent rescan | |
006ea71e TT |
6054 | feature which causes badblocks to run until it has completed some |
6055 | number of passes without discovering any new bad blocks. | |
ab146766 TT |
6056 | |
6057 | Badblocks now checks to see if the device is mounted and refuses to do | |
6058 | the tests involving writing to the device if it is mounted. Also, | |
6059 | badblocks now allows the number of blocks to be checked to be | |
6060 | defaulted to the size of the partition. | |
6061 | ||
6062 | Fixed a bug in fsck which didn't allow non-root users to be able to | |
6063 | check filesystems if there were any LABEL= or UUID= entries in | |
6064 | /etc/fstab. | |
6065 | ||
6066 | The Hurd doesn't support the filetype filesystem feature. The mke2fs | |
6067 | program now makes sure that for the Hurd, the filestype feature is | |
6068 | turned off. E2fsck will check to see if the filetype feature is | |
6069 | turned on for Hurd filesystems, and offer to turn off the feature. | |
6070 | ||
6071 | Mke2fs now has a safety check to make sure the number of blocks do not | |
6072 | exceed 32 bits even on a 64 bit platform. | |
6073 | ||
6074 | Really fixed a bug in fsck to allow "fsck -As" to run interactive | |
6075 | fsck's. (For those people who like to do interactive fsck's in the | |
6076 | /etc/rc scripts!?!) | |
6077 | ||
6078 | Debugfs has a few new features: the rdump command, which will do a | |
6079 | recursive dump of a directory and all of its contents, and the lcd | |
6080 | command which does a local chdir (much like the ftp command of the | |
6081 | same name). In addition, the debugfs program and the open_filesystem | |
6082 | command now takes three new options: -b and -s, which allows the | |
6083 | blocksize and superblock location to be specified, and the -c option | |
6084 | which is used in catastrophic situations where the block group | |
6085 | descriptors are corrupt. If the -c option is specified, debugfs will | |
6086 | skip trying to read in the block and inode bitmaps. | |
6087 | ||
6088 | Debufs's lsdel command was fixed to handle bad blocks in the inode | |
6089 | table. | |
6090 | ||
6091 | A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use | |
6092 | 4 digit years. | |
6093 | ||
6094 | General improvements in error messages | |
6095 | ||
6096 | - Mke2fs prints a sane error message if the partition size is zero | |
6097 | (usually because the partition table wasn't reread by the | |
6098 | kernel due to the partition being busy), instead of "invalid | |
6099 | argument passed to ext2 library while initializing superblock". | |
6100 | ||
6101 | - Fsck now prints more self-explanatory message if an invalid UUID= | |
6102 | or LABEL= specification is passed to it. | |
6103 | ||
6104 | UUID library changed to use the LGPL. | |
6105 | ||
6106 | Fixed a bug in the UUID library where very rapid calls to the | |
6107 | time-based UUID generator could cause duplicate UUID's to be returned. | |
6108 | This was not a problem for e2fsprogs, but it could be a problem for | |
6109 | other users of the library. | |
6110 | ||
6111 | Make the UUID library more robust in the face of missing or an | |
6112 | improper /dev/urandom or /dev/random files. | |
6113 | ||
6114 | Added some random portability fixes for Solaris. | |
6115 | ||
6116 | Some minor man page updates. | |
6117 | ||
6118 | Fixed a memory leak in the ss library. | |
6119 | ||
6120 | ||
6121 | Programmer's notes: | |
6122 | ------------------- | |
6123 | ||
6124 | We now try to use lseek64 and open64 from the LFS if possible. | |
6125 | ||
6126 | The 3rd parameter in e2p's print_flags is now a flags word, instead of | |
6127 | a boolean option. | |
6128 | ||
6129 | The mark and unmark bitmap functions now return the previous state of | |
6130 | the bit that was being changed, which is useful for some speed | |
6131 | optimizations. | |
6132 | ||
6133 | The following functions have been added to enhance the badblocks list | |
6134 | handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and | |
6135 | ext2fs_badblocks_equal. | |
6136 | ||
6137 | The ext2 header files now have the latest journalling fields to the | |
6138 | superblock. | |
6139 | ||
6140 | The ext2fs_mkdir function in libext2fs now properly backs out of error | |
6141 | conditions robustly. | |
6142 | ||
6143 | Cleaned up makefiles: | |
6144 | - to cleanly compile with the -j flag. | |
6145 | - so distclean removes all generated files. | |
6146 | - so in case of an error while installing header files, the make aborts. | |
6147 | ||
6148 | Fix test_script so that it works correctly when compiling in the | |
6149 | source directory. | |
6150 | ||
31d1d0c8 TT |
6151 | The random UUID generation routine has been made slightly better in |
6152 | the case where /dev/random doesn't exist. (Use of randomly-based UUID | |
6153 | is still not recommended if /dev/random doesn't exist, however; it's | |
6154 | better to use the time/ethernet MAC address UUID in this case.) | |
ab146766 TT |
6155 | |
6156 | Clean up the build process so it's more friendly in case of missing | |
6157 | directories. | |
6158 | ||
6159 | The ext2fs header file can now be #include'd into C++ programs. | |
6160 | ||
6161 | The e2p.h header file is now installed. | |
6162 | ||
6163 | Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. | |
6164 | ||
6165 | ||

6167 | E2fsprogs 1.18 (November 10, 1999) |
6168 | ================================== | |
6169 | ||
6170 | Fix a core dumping bug in e2fsck if an imagic inode is present or | |
6171 | (more rarely) if the filesystem is badly corrupted enough that e2fsck | |
6172 | has to restart pass 1 processing. E2fsck now closes the filesystem | |
6173 | before freeing a large number of its data structures, so in the case | |
6174 | of future memory faults, at least the fixed filesystem will be fully | |
6175 | written out. | |
6176 | ||
6177 | If a filesystem doesn't support imagic inodes, and e2fsck discovers an | |
6178 | imagic inode, it will offer to clear the imagic flag. | |
6179 | ||
6180 | E2fsck will now offer to clear the immutable flag on special files | |
6181 | (device/socket/fifos) when running it in non-preen mode. | |
6182 | ||
6183 | E2fsck will now set the filetype when creating /lost+found, and when | |
6184 | connected orphaned inodes to /lost+found. | |
6185 | ||
6186 | Debugfs's ncheck and icheck commands now handles the case where there | |
6187 | are bad blocks in the inode table without bombing out. | |
6188 | ||
6189 | The badblocks list processing code has been made more efficiently for | |
6190 | appending a large number of (ordered) badblocks to the badblocks list. | |
6191 | ||
6192 | Some minor man page updates. | |
6193 | ||
6194 | Fsck now allows interactive e2fsck's when using fsck -As (not a common | |
6195 | mode, but some people like to do this in boot scripts for silly reasons). | |
6196 | ||
6197 | Programmer's notes: | |
6198 | ------------------- | |
6199 | ||
6200 | The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet | |
6201 | with the problem code convention. | |
6202 | ||
6203 | The badblocks list regression test program has been updated to work | |
6204 | with previously made API name changes. | |
6205 | ||
6206 | The ext2fs_free() command now uses the new badblocks API to avoid | |
6207 | using the compatibility layer. | |
6208 | ||
6209 | Added new regression test cases; the run_e2fsck test script now | |
6210 | supports the ability for a test case to run a prepratory command | |
6211 | before running e2fsck. | |
6212 | ||
28e1194e TT |
6213 | E2fsprogs 1.17 (October 26, 1999) |
6214 | ================================= | |
6215 | ||
6216 | Fixed nasty typo in fsck which caused parallelized fsck's to go into an | |
6217 | infinite loop. | |
6218 | ||
6219 | Fixed a bug in fsck where it used strncmp to compare a binary UUID, | |
6220 | thus potentially causing problems if a binary UUID contained a NULL | |
6221 | character. | |
6222 | ||
6223 | E2fsck now uses stricter checks for directory entries in pass 2: | |
6224 | zero-length filenames are not allowed; neither are 8 byte long | |
6225 | directory entries. | |
6226 | ||
6227 | The debugfs "dirty" command now clears the filesystem valid bit. | |
6228 | (Previously this just set the dirty-as-in-needs-writing-out-to-disk | |
6229 | bit in the in-core superblock image. The new functionality is more | |
6230 | what the user expects, and is more useful.) | |
6231 | ||
6232 | Added a debugging hook to test parallel fsck; if the environment | |
6233 | variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive | |
6234 | will be checked in parallel when they normally would not be. | |
6235 | ||
6236 | Programmer's notes: | |
6237 | ------------------- | |
6238 | ||
6239 | Fixed some #ifdef's for compilation under the Hurd OS. | |
6240 | ||
6241 | Fixed minor W2K compatibility problems. | |
6242 | ||
6243 | Fixed some miscellaneous GCC warnings. | |
6244 | ||
6245 | ||
8a31ffef TT |
6246 | E2fsprogs 1.16 (October 22, 1999) |
6247 | ================================= | |
6248 | ||
6249 | Fixed a race condition bug in fsck; when printing a progress bar, if | |
6250 | checking multiple filesystems in parallel, it was possible for fsck to | |
6251 | send e2fsck a SIGUSR1 signal before e2fsck had installed its signal | |
6252 | handler, which would cause it to terminate with a signal 10. | |
6253 | ||
6254 | E2fsck now properly handles filesystems that have the | |
6255 | INCOMPAT_FILETYPE feature turned on. It can be used to convert a | |
6256 | filesystem into using or not using FILETYPE feature. | |
6257 | ||
6258 | E2fsck now properly handles filesystems that have the IMAGIC feature | |
6259 | turned on (this is used on Linux AFS servers). | |
6260 | ||
6261 | The mke2fs program now creates filesystems that have the filetype and | |
6262 | sparse_superblock features enabled by default, unless it is run on a | |
6263 | pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, | |
6264 | so there is now a new flag -O which allows the user to specify with | |
6265 | which features she would like to create the filesystem; "mke2fs -O | |
6266 | none" will create a filesystsem compatible with 2.0 kernels. | |
6267 | ||
6268 | The tune2fs program now has a -O option which allows the user to set | |
6269 | and reset "safe" filesystem features. Currently, the only ones which | |
6270 | allows to be modified are the filetype and sparse_superblock features. | |
6271 | Note setting or clearing either feature will require running e2fsck on | |
6272 | the filesystem afterwards. (n.b. Clearing the sparse_superblock feature | |
6273 | requires that there is enough free space on the filesystem for the | |
6274 | extra superblocks which will be created by e2fsck.) | |
6275 | ||
6276 | Debugfs can now set and print filesystem features in the superblock | |
6277 | using the "features" command. Dumpe2fs will print out the complete | |
6278 | set of features when listing the superblock. | |
6279 | ||
6280 | Dumpe2fs has new options -f (force) and -h (header-only). | |
6281 | ||
6282 | Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead | |
6283 | message to come up. This could happen when decrementing or | |
6284 | incrementing a link count could result in an overflow. | |
6285 | ||
6286 | Fixed a bug in e2fsck where the block count on the lost+found | |
6287 | directory would not be properly incremented when the directory was | |
6288 | expanded to the point where an indirect block needed to be allocated. | |
6289 | ||
6290 | E2fsck now makes some additional sanity checks on the superblock to | |
6291 | avoid crashing or giving a memory allocation error if some of the | |
6292 | values in the superblock are unresonable (but the superblock otherwise | |
6293 | looks valid). | |
6294 | ||
6295 | Fixed a bug in e2fsck where a very badly corrupted filesystem might | |
6296 | require two passes to completely fix the filesystem. This happened if | |
6297 | an inode claimed blocks that was part of the filesystem metadata | |
6298 | (typically, when garbage was written into an inode table or indirect | |
6299 | block, since this kind of filesystem corruption normally doesn't | |
6300 | happen otherwise). | |
6301 | ||
6302 | On the Alpha, glibc declares st_flags although it isn't actually used; | |
6303 | the configure script was improved to detect this case so that | |
6304 | e2fsprogs can avoid using the non-functional stat field. | |
6305 | ||
6306 | The manual pages were updated to use a more consistent formatting | |
6307 | style consistent with standard Unix man pages. Mke2fs's man page | |
6308 | added documentation for a few previously undocumented options. | |
6309 | ||
6310 | Fixed minor display bugs in tune2fs and mke2fs. | |
6311 | ||
6312 | Programmer's notes: | |
6313 | ------------------- | |
6314 | ||
6315 | Improved portability of e2fsprogs to non-Unix systems (in particular, NT). | |
6316 | ||
6317 | Added features to parse and print feature strings into the e2p library. | |
6318 | (e2p_feature2string, e2p_string2feature, e2p_edit_feature). | |
6319 | ||
6320 | ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories | |
6321 | whose directory entries contain proper filetype information if the | |
6322 | filesystem supports it. | |
6323 | ||
6324 | ext2fs_link() now uses the low 3 bits of its flags parameter to pass | |
6325 | the directory entry filetype information. This is used to set the | |
6326 | directory entry filetype information if the filesystem supports it. | |
6327 | ||
6328 | Fixed a bug in ext2fs_expand_dir() where the block count in a | |
6329 | directory's inode would not be properly incremented when the directory | |
6330 | was expanded to the point where an indirect block needed to be | |
6331 | allocated. | |
6332 | ||
6333 | ||
a39f3efe | 6334 | E2fsprogs 1.15 (July 18, 1999) |
e2a99be6 | 6335 | ============================== |
6d53db3f TT |
6336 | |
6337 | Add configuration checks so that e2fsprogs will compile cleanly on | |
6338 | Linux 2.3 kernels that have renamed i_version to i_generation. | |
6339 | ||
e2a99be6 TT |
6340 | E2fsck now prints a progress/completion bar (and not just a simple |
6341 | spinner) if the -C0 option is requested or if it receives a SIGUSR1 | |
6342 | signal. Fsck will automatically manage the (potentially muliple) | |
6343 | e2fsck processes to print completion bars if it is given a -C option, | |
6344 | with the right thing happening if multiple filesystems are being | |
6345 | checked in parallel. | |
6346 | ||
6347 | Mke2fs now has better automatic hueristics to determine the filesystem | |
6348 | parameters to be used for a particular filesystem. Added a new option | |
6349 | -T which allows the user to specify how the filesystem is to be used, | |
6350 | which helps mke2fs do a better job selecting the filesystem parameters. | |
6351 | ||
a39f3efe TT |
6352 | Mke2fs now creates revision 1 filesystems by default, and with the |
6353 | sparse superblock feature enabled. The sparse superblock feature is | |
8a31ffef TT |
6354 | not understood by Linux 2.0 kernels, so they will only allow read-only |
6355 | mounts of filesystems with this sparse superblocks. | |
a39f3efe | 6356 | |
6d53db3f TT |
6357 | Fix bug where if /dev/null couldn't be opened (should never happen), |
6358 | e2fsck would hang in a tight loop. | |
6359 | ||
6360 | Make e2fsck handle the case where /lost+found isn't a directory. | |
6361 | ||
6362 | E2fsck now uses mallinfo if it exists to get accurate statistics about | |
6363 | its memory usage. | |
6364 | ||
6365 | Fix bug in e2fsck where it wouldn't check to see if a disconnected | |
6366 | inode had any problems before connecting it to /lost+found. | |
6367 | ||
6368 | Add check to e2fsck so it makes sure that total number of inodes in | |
6369 | the filesystem is a sane number. | |
6370 | ||
6371 | Fix fencepost error when clearing an the end of the block bitmap which | |
6372 | caused the last block in the bitmap not to get cleared. | |
6373 | ||
6374 | Cleaned up a number of messages in e2fsck: | |
6375 | * The message "Group's #'s copy of the group descriptor..." | |
6376 | was fixed so that the correct number would be displayed. | |
6377 | * Added missing space in the "disk write-protected" error messsage | |
6378 | * Cleaned up the error message printed when a non-interactive | |
6379 | e2fsck needs to abort a check because the filesystem | |
6380 | appears to be mounted. | |
6381 | ||
6382 | Added a new command-line utility, uuidgen, which will create and print | |
6383 | a UUID. | |
6384 | ||
6385 | Make debugfs's icheck command more robust by checking to make sure an | |
6386 | inode has valid blocks before interarting over the inode's blocks. | |
6387 | ||
6388 | UUID generation now uses a random-based scheme whenever possible to | |
6389 | prevent potential privacy problems. | |
6390 | ||
6391 | Man pages for all of the UUID functions in the lirbary were added. | |
6392 | ||
6393 | Fixed bug in fsck so it won't coredump if a filesystem not in | |
6394 | /etc/fstab is given to it. | |
6395 | ||
6396 | Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab | |
6397 | that most of the other mount utilities understands. | |
6398 | ||
6399 | Mke2fs will make a filesystem even if it appears mounted if the force | |
6400 | option is given. | |
6401 | ||
6402 | Dumpe2fs has new command-line options which allow a filesystem expert | |
6403 | to specify the superblock and blocksize when opening a filesystem. | |
6404 | This is mainly useful when examining the remains of a toasted | |
6405 | filesystem. | |
6406 | ||
6407 | The badblocks program has been updated to display correctly on disks | |
6408 | with large block numbers. | |
6409 | ||
e2a99be6 TT |
6410 | The badblocks program no longer gives spurious errors when errors |
6411 | occur on non-block boundaries, which is common if the blocksize is | |
6412 | larger than 1k. | |
6413 | ||
6d53db3f TT |
6414 | Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the |
6415 | MKE2FS_SYNC environment variable is set. This is to work around a VM | |
6416 | bug in the 2.0 kernel. I've heard a report that a RAID user was able | |
a39f3efe TT |
6417 | to trigger it even using a 2.2 kernel, but hopefully it will not be |
6418 | needed for most Linux 2.2 users. | |
6d53db3f TT |
6419 | |
6420 | Fixed miscellaneous documentation and man pages. | |
6421 | ||
6422 | Programmer's notes: | |
6423 | ------------------- | |
6424 | ||
6425 | Cleaned up functions such as pass1_get_blocks, pass1_read_inode which | |
6426 | in e2fsck's pass1.c really should have been static. | |
6427 | ||
6428 | The return value of the uuid_compare() function was changed to make it | |
6429 | match with the convetions used by strcmp, memcmp, and Paul Leach's | |
6430 | UUID sample document. | |
6431 | ||
6432 | The "make depend" process has now been made more automated; it now | |
6433 | automatically word-wraps the dependencies, and only replaces source | |
6434 | Makefile.in if there has been a change in the dependencies. Also, a | |
6435 | top-level "make depend" now recurses through all the subdirectories | |
6436 | automatically. | |
6437 | ||
6438 | The Makefile in .../util has been changed so that subst is built using | |
6439 | the native C compiler during a cross-compilation, since the subst | |
6440 | program is only used during the build process. Also add an explicit | |
6441 | rule to build util/subst by cd'ing to the correct directory and | |
6442 | running Makefile. | |
6443 | ||
6444 | The man directories are defined in terms mandir, so that the configure | |
6445 | script can override the location of the manual pages. | |
6446 | ||
6447 | The config files have been updated to recognize new machine types for | |
6448 | both the i386 and alpha families. | |
6449 | ||
6450 | Fsck has been modified so that it will accurately create an | |
6451 | fsck_instance even when the noexecute flag is set. This allows for | |
6452 | accurate debugging of the fsck pass structure. Also, when the verbose | |
6453 | flag is given twice, fsck will print debugging information about when | |
6454 | fsck is waiting for jobs to finish. | |
6455 | ||
6456 | ||
14790ed7 TT |
6457 | E2fsprogs 1.14 (January 9, 1999) |
6458 | ================================ | |
6459 | ||
6460 | Fix the fstab parsing code so that it can handle blank lines and | |
6461 | comment characters. Also, missing pass numbers need to be treated as | |
6462 | zero. | |
6463 | ||
6464 | Fixed a bug in e2fsck where under some circumstances (when e2fsck | |
6465 | needs to restart processing after fixing an egregious inconsistency) | |
6466 | it would try to access already freed memory. | |
6467 | ||
6468 | E2fsck now prints non-printable characters in directory entries and | |
6469 | pathnames using '^' and 'M-' notation. | |
6470 | ||
6471 | Fixed chattr so that it will ignore symbolic links when doing | |
6472 | recursive descent traversals. For both chattr and lsattr, no longer | |
6473 | print the version string unless the -V option is given. | |
6474 | ||
6475 | Allow the system administrator to directly specify the number of | |
6476 | inodes desired in the filesystem, for some special cases where this is | |
6477 | necessary. | |
6478 | ||
6479 | Fix portability problems so that e2fsprogs can be compiled under Linux | |
6480 | 1.2 systems and Solaris systems. | |
6481 | ||
6482 | Update the config.guess file with a more recent version that will | |
6483 | identify newer Linux platforms. | |
6484 | ||
6485 | Programmer's notes | |
6486 | ------------------ | |
6487 | ||
6488 | Ext2fs_read_inode and ext2fs_write_inode will now return an error if | |
6489 | an inode number of zero is passed to them. | |
6490 | ||
556ad132 TT |
6491 | E2fsprogs 1.13 (December 15, 1998) |
6492 | ================================== | |
6493 | ||
6494 | Fixed a bug in debugfs where an error messages weren't getting printed | |
6495 | when the ext2 library routines to read inodes returned errors in the | |
6496 | stat, cmri and rm commands. | |
6497 | ||
6498 | Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is | |
6499 | provided, it won't create an inode table smaller than the minimum | |
6500 | number of inodes required for a proper ext2 filesystem. | |
6501 | ||
6502 | Fsck now parses the /etc/fstab file directly (instead of using | |
6503 | getmntent()), so that it can distinguish between a missing pass number | |
6504 | field and pass number field of zero. This caused problems for | |
6505 | diskless workstations where all of the filesystems in /etc/fstab have | |
6506 | an explicit pass number of zero, and fsck could not distinguish this | |
6507 | from a /etc/fstab file with missing pass numbers. | |
6508 | ||
6509 | E2fsck will create a /lost+found directory if there isn't one in the | |
6510 | filesystem, since it's safer to create the lost+found directory before | |
6511 | it's needed. | |
6512 | ||
6513 | Fixed e2fsck so that it would detect bogus immutable inodes which | |
6514 | happen to be sockets and FIFO files, and offer to clear them. | |
6515 | ||
6516 | If a filesystem has multiple reasons why it needs to be checked, and | |
6517 | one of the reasons is that it is uncleanly mounted, e2fsck will print | |
6518 | that as the reason why the filesystem is being checked. | |
6519 | ||
6520 | Cleaned up the output routines of mke2fs so that it doesn't overflow | |
6521 | an 80 column display when formating really big filesystems. | |
6522 | ||
6523 | Added a sanity check to e2fsck to make sure that file descriptors 0, | |
6524 | 1, 2 are open before opening the hard disk. This avoids a problem | |
6525 | where a broken program might exec e2fsck with those file descriptors | |
6526 | closed, which would cause disastrous results if the kernel returns a | |
6527 | file descriptor for the block device which is also used by FILE * | |
6528 | stdout. | |
6529 | ||
6530 | Fixed up the e2fsck progress reporting functions so that the values | |
6531 | reliably reach 100% at the completion of all of the e2fsck passes. | |
6532 | ||
6533 | Fixed minor documentation bugs in man pages and usage messages. | |
6534 | ||
6535 | Programmer's notes: | |
6536 | ------------------- | |
6537 | ||
6538 | Fixed a number of lint warnings in the ext2fs library and potential | |
6539 | portability problems from other OS's header files that might define | |
6540 | CPP macros for names like "max" and "min". | |
6541 | ||
6542 | ext2fs_badblocks_list_add() has been made more efficient when it needs | |
6543 | to grow the bad blocks list. | |
6544 | ||
6545 | Fixed a bug in e2fsck which caused it to dereference a freed pointer | |
6546 | just before exiting. | |
6547 | ||
6548 | Fixed the substition process for generating the mk_cmds and compile_et | |
6549 | scripts so that they will work outside of the build tree. | |
6550 | ||
6551 | Add sanity check to e2fsck so that if an internal routine | |
6552 | (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer | |
6553 | and causing a core dump. This should never happen, but... | |
6554 | ||
a569671a | 6555 | E2fsprogs 1.12 (July 9, 1998) |
21d53850 TT |
6556 | ================================== |
6557 | ||
6558 | E2fsprogs now works with glibc (at least with the version shipped wtih | |
6559 | RedHat 5.0). The ext2fs_llseek() function should now work even with | |
6560 | i386 ELF shared libraries and if llseek() is not present. We also | |
6561 | explicitly do a configure test to see if (a) llseek is in libc, and | |
6562 | (b) if llseek is declared in the system header files. (See standard | |
6563 | complaints about libc developers don't understand the concept of | |
6564 | compatibility with previous versions of libc.) | |
6565 | ||
c9833a60 TT |
6566 | The ext2fs library now writes out the block group number in each of |
6567 | the superblock copies. This makes it easier to automatically | |
6568 | determine the starting block group of the filesystem when the block | |
6569 | group information is trashed. | |
6570 | ||
6571 | Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, | |
101c84f2 TT |
6572 | which means that e2fsprogs will ignore the high 8 bits of the |
6573 | directory entry's name_len field, so that it can be used for other | |
6574 | purposes. | |
6575 | ||
6576 | Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. | |
6577 | E2fsprogs will now support filesystems with 64-bit sized files. | |
6578 | ||
6579 | Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. | |
6580 | ||
21d53850 TT |
6581 | Added new program "e2label", contributed by Andries Brouwer. E2label |
6582 | provides an easy-to-use interface to modify the filesystem label. | |
6583 | ||
a4b2d3ce TT |
6584 | Fixed bug so that lsattr -v works instead of producing a core dump. |
6585 | ||
21d53850 TT |
6586 | Fixed a minor bug in mke2fs so that all groups with bad superblock |
6587 | backup blocks are printed (not just the first one). | |
a4b2d3ce TT |
6588 | |
6589 | Mke2fs will check the size of the device, and if the user specifies a | |
6590 | filesystem size larger than the apparent size of the device it will | |
6591 | print a warning message and ask if the user wants to proceed. | |
6592 | ||
c9833a60 TT |
6593 | E2fsck has a new option -C, which sends completion information to the |
6594 | specified file descriptor. For the most part, this is intended for | |
6595 | programs to use, although -C 0 will print a spinning character to the | |
6596 | stdout device, which may be useful for users who want to see something | |
6597 | happening while e2fsck goes about its business. | |
6598 | ||
21d53850 TT |
6599 | Fixed a bug in e2fsck which could cause a core dump when it needs to |
6600 | expand the /lost+found directory, and sometimes the bitmaps haven't | |
6601 | been merged in. Also fixed a related bug where ext2fs_write_dir_block | |
6602 | was used to write out a non-directory block. (Which would be bad on a | |
6603 | non-Intel platform with byte swapping going on.) | |
6604 | ||
6605 | Fixed bug in e2fsck where it would print a "programming error" message | |
6606 | instead of correctly identifying where a bad block was in used when | |
6607 | the bad block was in a non-primary superblock or block group | |
6608 | descriptor. Also fixed a related bug when sparse superblocks are in | |
6609 | use and there is a bad block where a superblock or block group | |
6610 | descriptor would have been in a group that doesn't include a | |
6611 | superblock. | |
6612 | ||
6613 | Fixed a bug in e2fsck (really in libext2fs's dblist function) where if | |
6614 | the block group descriptor table is corrupt, it was possible to try to | |
6615 | allocate a huge array, fail, and then abort e2fsck. | |
6616 | ext2fs_get_num_dirs() now sanity checks the block group descriptor, | |
6617 | and subsitutes reasonable values if the descriptors are obviously bogus. | |
6618 | ||
6619 | If e2fsck finds a device file which has the immutable flag set and the | |
6620 | i_blocks beyond the normal device number are non-zero, e2fsck will | |
6621 | offer to remove it, since it's probably caused by garbage in the inode | |
6622 | table. | |
6623 | ||
6624 | When opening a filesystem, e2fsck specially checks for the EROFS error | |
6625 | code, and prints a specific error message to the user which is more | |
6626 | user friendly. | |
6627 | ||
6628 | If the filesystem revision is too high, change the e2fsck to print | |
6629 | that this is either because e2fsck is out of date, or because the | |
6630 | superblock is corrupt. | |
6631 | ||
6632 | E2fsck now checks for directories that have duplicate '.' and '..' | |
6633 | entries, and fixes this corruption. | |
6634 | ||
6635 | E2fsck no longer forces a sync of the filesystem (with attendant sleep | |
6636 | calls) at all times. The ext2fs_flush() function now performs a sync | |
6637 | only if it needed to write data blocks to disk. | |
6638 | ||
6639 | Fixed a minor bug in e2fsck's pass1b's file cloning function, where | |
6640 | certain errors would not be properly reported. | |
6641 | ||
6642 | Updated and expanded a few points in the man pages which users | |
6643 | complained wheren't explicit enough. | |
6644 | ||
6645 | Added special case byte-swapping code if compiling on the PowerPC, to | |
6646 | accomodate the strange big-endian variant of the ext2 filesystem that | |
6647 | was previously used on the PowerPC port. | |
6648 | ||
6649 | ||
6650 | Programmer's notes: | |
6651 | ------------------- | |
6652 | ||
6653 | Removed C++ keywords from the ext2fs libraries so that it could be | |
6654 | compiled with C++. | |
6655 | ||
6656 | E2fsck's internal organization has now been massively reorganized so | |
6657 | that pass*.c don't have any printf statements. Instead, all problems | |
6658 | are reported through the fix_problem() abstraction interface. E2fsck | |
6659 | has also been revamped so that it can be called as a library from a | |
6660 | application. | |
6661 | ||
6662 | Added new fileio primitives in libext2fs for reading and writing | |
6663 | files on an unmounted ext2 filesystem. This interface is now used by | |
6664 | debugfs. | |
6665 | ||
6666 | Added a new libext2fs function for mapping logical block numbers of | |
6667 | a file to a physical block number. | |
6668 | ||
6669 | Added a new libext2fs function, ext2fs_alloc_block(), which allocates | |
6670 | a block, zeros it, and updates the filesystem accounting records | |
6671 | appropriately. | |
6672 | ||
6673 | Added a new libext2fs function, ext2fs_set_bitmap_padding(), which | |
6674 | sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. | |
6675 | ||
6676 | The libext2fs functions now use a set of memory allocation wrapper | |
6677 | functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, | |
6678 | instead of malloc, free, and resize. This makes it easier for us to | |
6679 | be ported to strange environments where malloc, et. al. aren't | |
6680 | necessarily available. | |
6681 | ||
6682 | Change the libext2fs fucntion to return ext2-specific error codes | |
6683 | (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using | |
6684 | and depending on the existence of system error codes (such as EEXIST | |
6685 | and ENOENT). | |
6686 | ||
6687 | Renamed io.h to ext2_io.h to avoid collision with other OS's header | |
6688 | files. | |
6689 | ||
6690 | Add protection against ext2_io.h and ext2fs.h being included multiple | |
6691 | times. | |
6692 | ||
6693 | The types used for memory lengths, etc. have been made more portable. | |
6694 | In generla, the code has been made 16-bit safe. Added Mark | |
6695 | Habersack's contributed DOS disk i/o routines. | |
6696 | ||
6697 | Miscellaneous portability fixes, including not depending on char's | |
6698 | being signed. | |
6699 | ||
6700 | The io_channel structure has a new element, app_data, which is | |
6701 | initialized by the ext2fs routines to contain a copy of the filesystem | |
6702 | handle. | |
6703 | ||
6704 | ext2fs_check_directory()'s callback function may now return the error | |
6705 | EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to | |
6706 | really do the checking, despite the presence of the callback function. | |
6707 | ||
6708 | ||
bc210074 TT |
6709 | E2fsprosg 1.11 (June 17, 1997) |
6710 | ============================== | |
6711 | ||
6712 | Fixed e2fsck to detect (previously ignored) conflicts between the | |
6713 | superblock or block group descriptors and block bitmaps, inode | |
6714 | bitmaps, and inode tables. | |
6715 | ||
6716 | Fixed bug in e2fsck so that when the message printed out when a block | |
6717 | or inode bitmap conflicts with other data, it has the correct group | |
6718 | number. | |
6719 | ||
6720 | Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed | |
6721 | to badblocks. This meant that not all of the filesystem was being | |
6722 | tested for bad blocks! | |
6723 | ||
6724 | Fixed an array boundary overrun case which cropped up in | |
6725 | ext2fs_badblocks_list_test when a user tried running "mke2fs -c | |
6726 | -b 4096". | |
6727 | ||
6728 | Adjusted the number of columns printed by mke2fs when displaying the | |
6729 | superblock backups to avoid running over 80 columns when making a | |
21d53850 | 6730 | really big filesystem. |
bc210074 TT |
6731 | |
6732 | Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, | |
6733 | dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar | |
6734 | fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). | |
6735 | ||
6736 | Programmer's notes: | |
6737 | ------------------- | |
6738 | ||
6739 | Fixed install rule in lib/ss so that ss_err.h is actually getting | |
6740 | installed. | |
6741 | ||
6742 | Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting | |
6743 | bassed back to the caller. | |
6744 | ||
6745 | Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been | |
6746 | setting the current inode number (which meant this function wasn't | |
6747 | working at all). | |
6748 | ||
6749 | Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all | |
6750 | blocks in the bitmap when increasing the size of the bitmap. | |
6751 | ||
6752 | Changed the initial number of blocks allocated by ext2fs_init_dblist() | |
6753 | to be more realistic. | |
6754 | ||
6755 | Added a new function ext2fs_allocate_group_table, which sets up the | |
6756 | group descriptor information (and allocates inode and block bitmaps, | |
6757 | and inode tables for a particular group). The function was created by | |
6758 | factoring out code form ext2fs_allocate_tables(). | |
6759 | ||
6760 | Added a new function ext2fs_move_blocks which takes a bitmap of the | |
6761 | blocks to be moved, and moves them to another location on the | |
6762 | boardboard. | |
6763 | ||
6764 | Make the unix_io channel's io_channel_flush implementation calls sync() | |
6765 | to to flush the kernel buffers to disk. | |
6766 | ||
6767 | Added a new function ext2fs_dblist_count returns the number of | |
6768 | directory blocks in dblist. | |
6769 | ||
6770 | ||
ae851482 TT |
6771 | E2fsprogs 1.10 (April 24, 1997) |
6772 | =============================== | |
6773 | ||
6774 | Mke2fs once again defaults to creating revision #0 filesystems, since | |
6775 | people were complaining about breaking compatibility with 1.2 kernels. | |
6776 | Warning messages were added to the mke2fs and tune2fs man pages that | |
6777 | the sparse superblock option isn't supported by most kernels yet (1.2 | |
6778 | and 2.0 both don't support parse superblocks.) | |
6779 | ||
6780 | Added new flag to mke2fs, -R <raid options>, which allows the user to | |
6781 | tell mke2fs about the RAID configuration of the filesystem. Currently | |
6782 | the only supported raid option is "stride" which specifies the width | |
6783 | of the RAID stripe. | |
6784 | ||
6785 | Fixed bug in e2fsck where pass1b would bomb out if there were any | |
6786 | blocks marked bad in the inode table. | |
6787 | ||
6788 | Fixed rare bug in mke2fs where if the user had a very unlucky number | |
6789 | of blocks in a filesystem (probability less than .002) the resulting | |
6790 | filesystem would be corrupt in the last block group. | |
6791 | ||
6792 | Fixed bug where if e2fsck tried to allocate a block to fix a | |
6793 | filesystem corruption problem and the filesystem had no free blocks, | |
6794 | ext2fs_new_block() would loop forever. | |
6795 | ||
6796 | The configure script now checks explicitly to see if "-static" works, | |
6797 | since that can't be assumed to be true --- RedHat doesn't install | |
6798 | libc-static by default. | |
6799 | ||
6800 | Fixed bug in libext2's block iterator functions where under some | |
6801 | cirmcustances, file with holes would cause the bcount parameter to the | |
6802 | callback function to be incorrect. This bug didn't affect any of | |
6803 | e2fsprogs programs, but it was discovered by Paul Mackerras, the | |
6804 | author of the PPC boot loader. | |
6805 | ||
6806 | Removed use of static variables to store the inode cache in libext2fs. | |
6807 | This caused problems if more than one filesystem was accessed via | |
6808 | libext2fs (static variables in libraries are generally a bad idea). | |
6809 | Again, this didn't affect e2fsprogs programs, but it was discovered by | |
6810 | Paul Mackerras. | |
6811 | ||
6812 | Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 | |
6813 | will compile cleanly with 1.2.13 kernels (even with a.out shared | |
6814 | libraries!) | |
6815 | ||
6816 | Programmer's notes: | |
6817 | ------------------- | |
6818 | ||
6819 | Added new functions to duplicate an ext2 filesystem handle, and its | |
6820 | associated substructure. New functions: ext2fs_dup_handle(), | |
6821 | ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). | |
6822 | Other structures, such as the io_channel and the inode_cache, now have | |
6823 | a ref count so that they only get freed when they are no longer used | |
6824 | by any filesystem handle. (These functions were added as part of the | |
6825 | development effort for an ext2 resizer). | |

6827 | E2fsprogs 1.09 (April 14, 1997) |
6828 | =============================== | |
6829 | ||
6830 | Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was | |
6831 | accidentally introduced in the 1.08 release. The overhead calculation | |
6832 | was accidentally removed, which caused ext2fs_initialize() to not | |
6833 | notice when the filesystem size needed to be adjusted down because | |
6834 | there wasn't enough space in the last block group. | |
6835 | ||
6836 | Fixed bug in version parsing library routine; it was always parsing | |
6837 | the library version string, instead of using the passed-in string. | |
6838 | ||
6839 | Clarified chattr man page. | |
6840 | ||
24757fa0 TT |
6841 | E2fsprogs 1.08 (April 10, 1997) |
6842 | =============================== | |
6843 | ||
6844 | E2fsck 1.07 was very slow when checking very large filesystems with a | |
6845 | lot of files that had hard links (i.e., news spools). This was fixed | |
6846 | by seriously revamping the icount abstraction. Added a formal test | |
6847 | suite for the icount abstraction. | |
6848 | ||
6849 | Debugfs now has a "-l" option to the "ls" command, which lists the | |
6850 | inode number, permissions, owner, group, size, and name of the files | |
6851 | in the directory. | |
6852 | ||
6853 | Fix a bug in e2fsck where when a directory had its blocks moved to | |
6854 | another location during the pass 1b processing, the directory block | |
6855 | list wasn't updated, so pass 2 wouldn't check (and correct) the | |
6856 | correct directory block. | |
6857 | ||
6858 | E2fsck will now treat inodes which contain blocks which are claimed by | |
6859 | the filesystem metadata by treating them as multiply claimed blocks. | |
6860 | This way, the data in those blocks can be copied to a new block during | |
6861 | the pass 1b--1d processing. | |
6862 | ||
6863 | E2fsck will attempt to determine the correct superblock number and | |
6864 | display it in the diagnostic and warning messages if possible. | |
6865 | ||
6866 | Add support for a new (incompatible) feature, "sparse_super". This | |
6867 | feature reduces the number of blocks which contain copies of backup | |
6868 | superblocks and block group descriptors. (It is only an incompatible | |
6869 | feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now | |
6870 | support a new -s option; e2fsck will recognize filesystems built with | |
6871 | this feature turned on. | |
6872 | ||
6873 | E2fsck now checks the library to make sure is the correct version, | |
6874 | using new library functions. (This helps to diagnose incorrectly | |
6875 | installed e2fsprogs distributions.) | |
6876 | ||
6877 | Dumpe2fs now prints more information; its now prints the the | |
6878 | filesystem revision number, the filesystem sparse_super feature (if | |
6879 | present), the block ranges for each block group, and the offset from | |
6880 | the beginning of the block group. | |
6881 | ||
6882 | Mke2fs now distributes the inode and block bitmap blok so that the | |
6883 | won't be concentrated in one or two disks in RAID/striping setups. | |
6884 | Also, if the user chooses a 2k or 4k block group, mke2fs will try to | |
6885 | choose the largest blocks per group that be chosen. (For 2k blocks, | |
6886 | you can have up to 16384 blocks/group; for 4k blocks, you can have up | |
6887 | to 32768 blocks/group.) Previously mke2fs would not allow | |
6888 | specification of more than 8192 blocks per group, even if you were | |
6889 | using a 2k or 4k block group. | |
6890 | ||
6891 | Programmer's notes: | |
6892 | ------------------- | |
6893 | ||
6894 | Added a new function ext2fs_create_icount2() which takes a "hint" | |
6895 | argument. This hint argument presets the icount array with the list | |
6896 | of inodes which actually need to be in the icount array. This really | |
6897 | helps to speed up e2fsck. | |
6898 | ||
6899 | Added a new function ext2fs_icount_validate() which checks the rep | |
6900 | invariant for the icount structure. This is used mostly for testing. | |
6901 | ||
6902 | The error mesasage given when a bad inode number is passed to | |
6903 | test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of | |
6904 | EXT2FS_UNMARK_ERROR). | |
6905 | ||
6906 | Added a new function ext2fs_set_dir_block which sets the block of a | |
6907 | dblist entry, given the directory inode and blockcnt. | |
6908 | ||
6909 | Added a new function ext2fs_get_library_version() which returns the | |
6910 | current library version, and ext2fs_parse_version_string() which | |
6911 | returns a version number based on a e2fsprogs version string. | |
6912 | ||
6913 | The icount functions will return EINVAL if the passed in inode number | |
6914 | is out of bounds. | |
6915 | ||
21c84b71 TT |
6916 | E2fsprogs 1.07 (March 9, 1997) |
6917 | ============================== | |
6918 | ||
6919 | E2fsck is now uses much less memory when checking really large | |
6920 | filesystems (or rather, filesystems with a large number of inodes). | |
6921 | Previously a filesystem with 1 million inodes required 4 megabytes of | |
6922 | memory to store inode count statistics; that storage requirement has | |
6923 | now been reduced to roughly half a megabyte. | |
6924 | ||
6925 | E2fsck can now properly deal with bad blocks appearing inside the | |
6926 | inode table. Instead of trying to relocate the inode table (which | |
6927 | often failed because there wasn't enough space), the inodes in the bad | |
6928 | block are marked as in use. | |
6929 | ||
6930 | E2fsck will automatically try to use the backup superblocks if the | |
6931 | primary superblocks have a bad magic number or have missing meta-data | |
6932 | blocks (or meta-data blocks which are out of range). | |
6933 | ||
6934 | E2fsck's pass 3 has been made more efficient; most noticeable on | |
6935 | filesystems with a very large number of directories. | |
6936 | ||
6937 | Completely revamped e2fsck's system of printing problem reports. It | |
6938 | is now table driven, to make them more easily customizeable and | |
6939 | extendable. Error messages which can be printed out during preen mode | |
6940 | are now one line long. | |
6941 | ||
6942 | Fixed e2fsck's filesystem swapping code so that it won't try to swap | |
6943 | fast symbolic links or deleted files. | |
6944 | ||
6945 | Fixed e2fsck core dumping when fixing a filesystem which has no | |
6946 | directories (not even a root directory). | |
6947 | ||
6948 | Added a check to e2fsck to make sure that the length of every | |
6949 | directory entry is a multiple of 4 (since the kernel complains if it | |
6950 | isn't). | |
6951 | ||
6952 | Added a check to e2fsck to make sure that a directory entry isn't a | |
6953 | link to the root directory, since that isn't allowed. | |
6954 | ||
6955 | Added a check to e2fsk to now make sure the '.' and '..' directory | |
6956 | entries are null terminated, since the 2.0 kernel requires it. | |
6957 | ||
6958 | Added check to write_bitmaps() to make sure the superblock doesn't get | |
6959 | trashed if the inode or block bitmap is marked as being block zero. | |
6960 | ||
6961 | Added checking of the new feature set fields in the superblock, to | |
6962 | avoid dealing with new filesystem features that this package wasn't | |
6963 | set up to handle. | |
6964 | ||
6965 | Fixed a fencepost error in ext2fs_new_block() which would occasionally | |
6966 | try to allocate a block beyond the end of a filesystem. | |
6967 | ||
6968 | When the UUID library picks a random IEEE 802 address (because it | |
6969 | can't find one from a network card), it sets the multicast bit, to | |
6970 | avoid conflicting with a legitimate IEEE 802 address. | |
6971 | ||
6972 | Mke2fs now sets the root directory's owner to be the real uid of the | |
6973 | user running mke2fs. If the real uid is non-zero, it also sets | |
6974 | the group ownership of the root directory to be the real group-id of | |
6975 | the user running mke2fs. | |
6976 | ||
6977 | Mke2fs now has more intelligent error checking when it is given a | |
6978 | non-existent device. | |
6979 | ||
6980 | When badblocks is given the -vv option, it now updates the block that | |
6981 | it is currently testing on every block. | |
6982 | ||
6983 | Fixed a bug in fsck where it wouldn't modify the PATH envirnoment | |
6984 | currently correctly if PATH wasn't already set. | |
6985 | ||
6986 | Shared libraries now built with dependencies. This allows the shared | |
6987 | library files to be used with dlopen(); it also makes the transition | |
6988 | to libc 6 easier, since ld.so can tell which libc a particular shared | |
6989 | library expects to use. | |
6990 | ||
6991 | Programmer's notes: | |
6992 | ------------------- | |
6993 | ||
6994 | Added new abstraction (defined in dblist.c) for maintaining a list of | |
6995 | blocks which belongs to directories. This is used in e2fsck and other | |
6996 | programs which need to iterate over all directories. | |
6997 | ||
6998 | Added new functions which test to see if a contiguous range of blocks | |
6999 | (or inodes) are available. (ext2fs_*_bitmap_range). | |
7000 | ||
7001 | Added new function (ext2_inode_has_valid_blocks) which returns true if | |
7002 | an inode has valid blocks. (moved from e2fsck code). | |
7003 | ||
7004 | Added new function (ext2fs_allocate_tables) which allocates the | |
7005 | meta-data blocks as part of initializing a filesystem. (moved from | |
7006 | mke2fs code). | |
7007 | ||
7008 | Added a new I/O manager for testing purposes. It will either allow a | |
7009 | program to intercept I/O requests, or print debugging messages to | |
7010 | trace the activity of a program using the I/O manager. | |
7011 | ||
7012 | The badblocks_list functions now store the bad blocks in a sorted | |
7013 | order, and use a binary search to speed up badblocks_list_test. | |
7014 | ||
7015 | The inode scan function ext2fs_get_next_inode() may now return a soft | |
7016 | error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in | |
7017 | those cases where part of an inode table is missing or there is a bad | |
7018 | block in the inode table. | |
7019 | ||
7020 | Added a new function (ext2fs_block_iterate2) which adds new arguments to | |
7021 | the callback function to return a pointer (block and offset) to the | |
7022 | reference of the block. | |
7023 | ||
7024 | Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an | |
7025 | application to jump to a particular block group while doing an inode | |
7026 | scan. | |
7027 | ||
7028 | The badblocks list functions were renamed from badblocks_* to | |
7029 | ext2fs_badblocks_*. Backwards compatibility functions are available | |
7030 | for now, but programs should be modified to use the new interface. | |
7031 | ||
7032 | Some of the library functions were reorganized into separate files to | |
7033 | reduce the size of some programs which statically link against the | |
7034 | ext2 library. | |
7035 | ||
7036 | Put in some miscellaneous fixes for the Alpha platform. | |

7038 | |
7039 | E2fsprogs 1.06 (October 7, 1996) | |
7040 | ================================ | |
7041 | ||
7042 | Fixed serious bug in e2fsck: if the block descriptors are bad, don't | |
7043 | smash the backup copies in ext2fs_close(). (The problem was that when | |
7044 | e2fsck -p discovered the problem, while it was closing the filesystem | |
7045 | and exiting, it was also blowing away the backup superblocks on the | |
7046 | disk, which was less than friendly.) We now make it the case that we | |
7047 | only write out the backup superblock and the back block descriptors if | |
7048 | the filesystem is completely free from problems. | |
7049 | ||
7050 | Fixed a bug in block_interate in the lib/ext2fs library which caused | |
7051 | e2fsck to fail on GNU Hurd-created filesystems. | |
7052 | ||
7053 | Add support for Linux/FT's bootloader, which actually uses | |
7054 | EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want | |
7055 | to clear the inode. | |
7056 | ||
7057 | Add support for the "A" (no atime update) attribute. (Note: this | |
7058 | attribute is not yet in production kernels.) | |
7059 | ||
7060 | The test suite is not automatically run when doing a "make all" from | |
7061 | the top level directory. Users should manually run "make check" if | |
7062 | they wish to run the test suite. | |
7063 | ||
7064 | Upon a preenhalt(), make the printed message more explicit that | |
7065 | running e2fsck "MANAULLY" means without the -p or -a options. | |
7066 | ||
7067 | In e2fsck, if a disconnected inode is zero-length, offer to clear it | |
7068 | instead of offering to connect it to lost+found. | |
7069 | ||
7070 | In e2fsck, if a filesystem was just unmounted uncleanly, and needs | |
7071 | e2fsck to be run over it, change e2fsck to explicitly display this | |
7072 | fact. | |
7073 | ||
7074 | For dumpe2fs and e2fsck, cause the -V option to print out which | |
7075 | version of the ext2fs library is actually getting used. (This will | |
7076 | help detect mismatches of using a 1.06 utility with a 1.05 library, | |
7077 | etc.) | |
7078 | ||
7079 | Programmers' notes: | |
7080 | ------------------- | |
7081 | ||
7082 | EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits | |
7083 | the naming convention. | |
7084 | ||
7085 | In ext2fs_initialize(), make sure the description for the inode bitmap | |
7086 | is correctly initialize. | |
7087 | ||
7088 | Fixed minor type typo in ext2fs_allocate_generic_bitmap(); | |
7089 | ||
fc6d9d51 TT |
7090 | E2fsprogs 1.05 (September 7, 1996) |
7091 | ================================== | |
7092 | ||
7093 | Add support for new fields in the ext2 superblock --- volume name, | |
7094 | volume UUID, and last mounted field. Dumpe2fs displays these fields, | |
7095 | tune2fs and mke2fs allows you to set them. E2fsck will automatically | |
7096 | generate a UUID for those volumes that don't have them. | |
7097 | ||
7098 | Put in support for e2fsck to recognize HURD specific ext2 features --- | |
7099 | most notably, the translator block. The e2fsprogs tools will now use | |
7100 | the creator_os field in the superblock to correctly handle different | |
7101 | OS-specific variants of the ext2 filesystem. | |
7102 | ||
7103 | E2fsck now fixes inodes which have a the deletion time set, but which | |
7104 | have a non-zero i_link_count field by offering to clear the deletion | |
7105 | time. Previously e2fsck assumed that the inode was deleted (per 0.3c | |
7106 | ext2 kernel behavior) and offered to unlink the file. | |
7107 | ||
7108 | If e2fsck sets the clean bit, but nothing else, set the exit code | |
7109 | FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it | |
7110 | set the filesystem valid bit when it was previously cleared. :-) This | |
7111 | was needed to make the HURD fsck driver happy. | |
7112 | ||
7113 | If the user refuses to attach an unattached inode, e2fsck will no | |
7114 | longer set the inode's link count. Otherwise, the inode would end up | |
7115 | getting marked as unused, which might cause loss of data later. | |
7116 | ||
7117 | Make the message issued by e2fsck when the superblock is corrupt less | |
7118 | confusing for users. It now mentions that another reason for the | |
7119 | "corrupt superblock" message might be that the partition might not be | |
7120 | an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) | |
7121 | ||
7122 | Make the libext2 library more robuest so that e2fsck won't coredump on | |
7123 | an illegal superblock where the blocksize is zero. (f_crashdisk is | |
7124 | the test case). | |
7125 | ||
7126 | By default, create filesystems where the default checkinterval is 6 | |
7127 | months (180 days). Linux servers can be robust enough that 20 reboots | |
7128 | can be a long, long time. | |
7129 | ||
7130 | Added configure flag --enable-old-bitops, which forces the bitops to | |
7131 | use the old (native) bitmask operations. By default on the sparc | |
7132 | platform, the standard ext2 bit ordering is now used. | |
7133 | ||
7134 | Added a new feature to e2fsck to byte-swap filesystems; this can be | |
7135 | used to convert old m68k filesystems to use the standard byte-order | |
7136 | storage for the superblock, inodes, and directory blocks. This | |
7137 | function is invoked by using the '-s' option to e2fsck. | |
7138 | ||
7139 | Debugfs's "dump" command has been enhanced so that it writes out the | |
7140 | exact size of the file so that the nulls at the end of the file are | |
7141 | eliminated. The command also accept a new "-p" option which will | |
7142 | attempt preserve to preserve the ownernship, permissions, and | |
7143 | file modification/access times. | |
7144 | ||
7145 | Debugfs has two new options, -f and -R. The -R option allows the user | |
7146 | to execute a single debugfs command from the command line. The -f | |
7147 | option allows the user to specify a "command file" containing debugfs | |
7148 | commands which will get executed. | |
7149 | ||
7150 | Dumpe2fs now pretty prints the check interval, instead of just | |
7151 | printing the check interval as a number of seconds. | |
7152 | ||
7153 | Fix bugs in debugfs: the params command when no filesystem is opened | |
7154 | no longer causes a core dump. It is now possible to unlink a file | |
7155 | when a pathame containing a '/' is specified. | |
7156 | ||
7157 | Tune2fs has a new -C option which sets the number of times the | |
7158 | filesystem has been mounted. | |
7159 | ||
7160 | Fix the chattr '-v' option so that it actually works. Chattr was | |
7161 | being buggy about the -v option parsing. | |
7162 | ||
7163 | Programmers' notes: | |
7164 | ------------------- | |
7165 | ||
7166 | The directory lib/uuid contains a set of library routines to generate | |
7167 | DCE compatible UUIDs. | |
7168 | ||
7169 | Extended ext2fs_namei() to handle symbolic links. Added new function | |
7170 | ext2fs_nami_follow() which will follow last symbolic link in the case | |
7171 | where the pathname points to a sym link. | |
7172 | ||
7173 | The ext2fs_block_iterate function will now return the HURD translator | |
7174 | block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the | |
7175 | iterator to return data blocks only. The ext2fs.h file now defines | |
7176 | constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and | |
7177 | BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block | |
7178 | count field of the iterator callback function. | |
7179 | ||
7180 | The test script driver now takes an optional second argument, which is | |
7181 | the test case to be run. This allows you to run a test case without | |
7182 | needing to run the entire test suite. | |
7183 | ||
7184 | On Linux ELF systems, install the .so files in the correct places | |
7185 | (/usr/lib). The .so files must be stored in the same directory as the | |
7186 | .a files. | |
7187 | ||
7188 | Fixed miscellaneous HURD compilation issues with header file being | |
7189 | included in the right order. | |
7190 | ||
7191 | Fixed debugfs so that it resets optind to zero, not one, since setting | |
7192 | optind to zero is more correct. | |
7193 | ||

7195 | E2fsprogs 1.04 (May 16, 1996) |
7196 | ============================= | |
7197 | ||
7198 | First "official" (1.03 was a limited release only) to support building | |
7199 | e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 | |
7200 | kernels). | |
7201 | ||
7202 | This package includes a RPM specs file, that it can be built using the | |
7203 | RedHat Package Manager. | |
7204 | ||
7205 | E2fsck now prints a hint that if there are lots of incorrectly located | |
7206 | inode bitmaps, block bitmaps, and inode table blocks, the user might | |
7207 | want to try using e2fsck -b 8193 first, to see if that fares any | |
7208 | better. | |
7209 | ||
7210 | For ext2 filesystem written with the hurd, debugfs will now print out | |
7211 | the translator field when printing an inode structure. | |
7212 | ||
7213 | Lots of miscellaneous linking/installation cleanups: | |
7214 | ||
7215 | Libraries are now linked using a relative pathname, instead of | |
7216 | relying on -L working correct. It doesn't, in many cases, including | |
7217 | current versions of GNU ld. This guarantees that the build tree is | |
7218 | linking with the right libraries, instead of the ones installed in | |
7219 | /usr/lib. | |
7220 | ||
7221 | Header files, man pages, and the et/ss shell scripts are now | |
7222 | generated using a custom substitution script, instead of relying on | |
7223 | the configure script. This prevents needless recompilation of | |
7224 | files; in addition, the custom substitution script is much faster. | |
7225 | ||
7226 | e2fsck may now be linked dynamically, by using the | |
7227 | --enable-dynamic-e2fsck flag to configure. This is not recommended, | |
7228 | since it increases e2fsck's dependence on other files, but some | |
7229 | people need to save disk space, and other critical programs on their | |
7230 | systems were being linked dynamically anyway. | |
7231 | ||
7232 | Programs such as fsck which didn't need to be linked against | |
7233 | libext2fs (or mke2fs which didn't need to be linked against libe2p) | |
7234 | only link against libraries they actually need. Otherwise, those | |
7235 | programs would require the presense of libraries that otherwise | |
7236 | could be removed from a rescuse diskette. | |
7237 | ||
7238 | The ss include files are now installed correctly so they can | |
7239 | actually be used by another package. | |
7240 | ||
7241 | If the profiling libraries are built, they are now installed on a | |
7242 | "make install-libs". | |

7245 | E2fsprogs 1.03 (March 27, 1996) |
7246 | =============================== | |
7247 | ||
7248 | Change the m68k bit numbering for bitmasks to match the bit numbering | |
7249 | used by all other ext2 implementations. (This change was requested by | |
7250 | the m68k kernel development team.) | |
7251 | ||
7252 | Support (in-development) filesystem format revision which supports | |
7253 | (among other things) dynamically sized inodes. | |
7254 | ||
7255 | Fixed a bug in the ext2 library so that an intelligent error is | |
7256 | returned if mke2fs is run with a ridiculously small number of blocks | |
7257 | for a partition. | |
7258 | ||
7259 | Fixed a bug in the ext2 library which required that the device be | |
7260 | openable in read/write mode in order to determine its size. This | |
7261 | caused e2fsck -n to require read/write access when it was not | |
7262 | previously necessary. | |
7263 | ||
7264 | Fixed a bug in e2fsck which casued it to occasionally fail the test | |
7265 | suite depending on which version of the floating point library it was | |
7266 | using. | |
7267 | ||
7268 | Fixed a bug in e2fsck so that it now halts with a fatal error when | |
7269 | certain superblock consistency checks fail. Previously it continued | |
7270 | running e2fsck, with some potential confusing/damaging consequences. | |
7271 | ||
7272 | Added new flag to fsck which allows the root to be checked in parallel | |
7273 | with other filesytems. This is not the safest thing in the world to | |
7274 | do, but some system administrators really wanted it. | |
7275 | ||

7276 | Fixed -Wall flames in lib/ss. |

7279 | E2fsprogs 1.02 (January 16, 1996) | |
7280 | ================================= | |
7281 | ||
7282 | Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. | |
7283 | ||
7284 | Change e2fsck to print statistics of how many non-contiguous files are | |
7285 | on the system. Note that a file which is larger than 8k blocks, it is | |
7286 | guaranteed to be non-contiguous. | |
7287 | ||
7288 | In mke2fs, print a warning message if a user tries to format a whole | |
7289 | disk (/dev/hda versus /dev/hda1). If a user really wants to format a | |
7290 | whole disk, the -F (force) option forces mke2fs to format a whole disk | |
7291 | as a filesytem. | |
7292 | ||
7293 | Fix a bug in fsck where in some cases it might start checking | |
7294 | partitions in the next pass before it finishes checking partitions in | |
7295 | the current pass. This still won't cause two partitions on the same | |
7296 | disk will be checked, so it's rarely a problem in real life. | |
7297 | ||
7298 | Patch lsattr so that it won't hang when checking a named pipe. | |
7299 | ||
7300 | Minor compilation fixes: | |
7301 | * Fix the order of libraries that were linked in debugfs. | |
7302 | * Allow the sources to be compiled with -ansi turned on. |
