1 | E2fsprogs 1.41.1 (as of August 23, 2008) commit id baf8ab98 |
2 | ============================================================ | |
3 | ||
4 | Many people are forgetting to update their mke2fs.conf file, and this | |
5 | causes ext3, ext4, and ext4dev filesystems won't get created with the | |
6 | proper features enabled. We address this in two ways. First, mke2fs | |
7 | will issue a warning if there is not definition for an ext3, ext4, or | |
8 | ext4dev filesystem and the user is trying to create such a filesystem | |
9 | type. Secondly, when installing from a source build, "make install" | |
10 | will provide basic configuration file handling for /etc/mke2fs.conf. | |
11 | If it exists, and does not mention ext4dev, it will be moved aside to | |
12 | /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will | |
13 | be installed. If the existing /etc/mke2fs.conf file does mention | |
14 | ext4dev, then "make install" will install official mke2fs.conf file as | |
15 | /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that | |
16 | they should look to see if any changes need to be merged. | |
17 | ||
18 | Mke2fs and tune2fs now print the correct usage message describing the | |
19 | maximum journal size. (Addresses Debian Bug: #491620) | |
20 | ||
21 | The blkid library will now recognize MacOS hfsx filesystems, and | |
22 | correctly extract the label and uuid for hfs, hfsx, and hfsplus | |
23 | filesystems. (Addresses Sourceforge Feature Requests: #2060292) | |
24 | ||
25 | Resize2fs will now properly close out the "updating inode references" | |
26 | progress bar so there is a newline printed before printing the final | |
27 | "resize is successful" message. | |
28 | ||
29 | Resize2fs will now correctly handle filesystems with extents and/o | |
30 | uninitialized block groups correctly when file/directory blocks need | |
31 | to relocated (i.e., when shrinking a filesystem or if the resize_inode | |
32 | is not present). To support this, the ext2fs library now supports | |
33 | initializing inode and block bitmaps that are not yet initialized when | |
34 | allocating them using ext2fs_new_block() and ext2fs_new_inode(). In | |
35 | addition, e2fs_block_iterate2() can now support changing the location | |
36 | of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has | |
37 | been optimized to avoid creating unnecessary new extents when updating | |
38 | the location of blocks in the extent tree. This will also help out | |
39 | e2fsck's recovery of obscurely corrupted filesystems with extents, | |
40 | when blocks are claimed by multiple inodes. | |
41 | ||
42 | E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and | |
43 | debugfs programs to not be able to read e2image files; the signed | |
44 | vs. unsigned bug in the code which read bitmaps from the e2image has | |
45 | been fixed. (Addresses Debian Bug: #495830) | |
46 | ||
47 | Resize2fs is now correctly managing the directory in-use counts when | |
48 | shrinking filesystems and directory inodes needed to be moved from one | |
49 | block group to another. This bug has been around since e2fsprogs | |
50 | 1.26, and is largely harmless, but does cause a filesystem corruption | |
51 | which will be flagged by e2fsck after the filesystem has been shrunk. | |
52 | ||
53 | E2fsck will no longer issue spurious complaints about the inode size | |
54 | caused by very large extent-based files, and by blocks reallocated | |
55 | using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses | |
56 | Kernel Bugzilla: #11341) | |
57 | ||
58 | Mke2fs will now set the creation timestamp on the lost+found directory | |
59 | and the root directory. (More generally, all new inodes created using | |
60 | the ext2fs library will correctly set the creation timestamp.) | |
61 | ||
62 | E2fsck now correctly calculates ind/dind/tind statistics in the | |
63 | presence of extent-based files. In addition, "e2fsck -v" will report | |
64 | statistics of the depth of extent trees in the filesystem. E2fsck can | |
65 | also give an inode fragmentation report using "e2fsck -E fragcheck" | |
66 | which can be useful when debugging the kernel block allocation | |
67 | routines. | |
68 | ||
69 | Blkid had a number of cache validation bugs in libblkid that have been | |
70 | fixed. (Addresses Debian Bug: #493216) | |
71 | ||
72 | Debugfs's htree command now correctly understands extent-based | |
73 | directories. It will also print out the minor hash as well as the | |
74 | major hash. | |
75 | ||
76 | The error message printed by "tune2fs -I" if the inode size was too | |
77 | small was rather confusing, so it has been improved. Also, we won't | |
78 | try to create an undo log until we know that command-line-specified | |
79 | parameters such as "tune2fs -I <inode size>" are valid. | |
80 | ||
81 | Mke2fs will correctly enforce the prohibition against features | |
82 | (specifically read-only features) in revision 0 filesystems. (Thanks | |
83 | to Benno Schulenberg for noticing this problem.) | |
84 | ||
85 | Mke2fs previously would occasionaly create some slightly non-optimally | |
86 | placed inode tables; this bug has been fixed. | |
87 | ||
88 | Given some filesystems found "in the wild" that had non-zero block | |
89 | group checksums even though the uninit_bg/gdt_sum feature was not | |
90 | enabled, e2fsck would issue spurious error messages. Teach | |
91 | ext2fs_group_desc_csum_verify() to ignore the block group checksum | |
92 | entirely if the feature flag is not set. (Addresses Debian Bug: | |
93 | #490637) | |
94 | ||
95 | The blkid program will now print out a user-friendly listing of all of | |
96 | the block devices in the system and what they contain when given the | |
97 | -L option. (Addresses Debian Bug: #490527) | |
98 | ||
99 | Typographical errors in various program strings and usage messages | |
100 | have been fixed; most of these were pointed out by the e2fsprogs | |
101 | message catalog translators. (Thanks, translators!) | |
102 | ||
103 | Update and clarified various man pages, as well as some typographical | |
104 | errors in the libext2fs texinfo file. | |
105 | ||
106 | Fixed various Debian packaging issues --- see debian/changelog for | |
107 | details. | |
108 | ||
109 | Add Indonesian and update French, Polish, Dutch, German, Sweedish, | |
110 | Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697, | |
111 | #401092) | |
112 | ||
113 | Programmer's Notes | |
114 | ------------------ | |
115 | ||
116 | Fix portability problem with the badblocks group; for systems that | |
117 | don't have nanosleep(), try using usleep() instead. | |
118 | ||
119 | The "make check" target in the e2fsck directory now sets | |
120 | LD_LIBRARY_PATH before running the various e2fsck internal library | |
121 | regression tests. | |
122 | ||
123 | The crc32 regression test in the e2fsck library is now portable to | |
124 | greater varienty of environments, including big-endian systems and | |
125 | when cross-building e2fsprogs for embedded systems. (Addresses | |
126 | Sourceforge Bug: #2019287) | |
127 | ||
128 | The ext2fs_extent_set_bmap() had some bugs when setting the first | |
129 | block in a file, or when replacing a single block extent. Those cases | |
130 | fortunately were came up relatively rarely when e2fsck was checking | |
131 | files, but caused some problems when resize2fs was shrinking | |
132 | extent-based files. | |
133 | ||
134 | Various ext2fs library functions --- ext2fs_initialize() and | |
135 | ext2fs_extent_open() --- now correctly free allocated memory to avoid | |
136 | memory leaks in all of their error return paths. | |
137 | ||
138 | Ext2ed was failing to build because masix support had been removed in | |
139 | the rest of e2fsprogs, so ext2ed no longer has masix support, either. | |
140 | ||
141 | The configure script now respects the LDFLAGS environment variable if | |
142 | it is set when configure is called. (Addresses Sourceforge Feature | |
143 | Request: #1937287) | |
144 | ||
145 | Libuuid is now more portable to the Windows platform. (Addresses | |
146 | Sourceforge Feature Request: #1937287) | |
147 | ||
148 | The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of | |
149 | bare echo commands so that configure flags such as --quiet work | |
150 | correctly. (Addresses Sourceforge Patches: #2058794) | |
151 | ||
152 | A few uses of sprintf have been removed from the ext2fs library to | |
153 | make life easier for bootloaders with a limited libc environment. | |
154 | (Addresses Sourceforge Bug: #2049120) | |
155 | ||
156 | The ext2fs_read_inode() checks the validity of the inode number passed | |
157 | to it earlier, to avoid doing some needless work when it would fail | |
158 | anyway. | |
159 | ||
160 | The ext2fs_open() checks the validity of the blocksize parameter | |
161 | passed to it earlier, to avoid doing some needless work when it would | |
162 | fail anyway. | |
163 | ||
164 | Disable a very annoying automatic "%.sh -> %" GNU make rule in the | |
165 | top-level Makefile. That automatic rule is used to better support | |
166 | SCCS, but it caused problems for a particular niche distribution which | |
167 | likes to use configure.sh files to store the configure options used to | |
168 | build a package. Unfortuntaely GNU make will use the configure.sh to | |
169 | replace the configure script, resulting in a self-inflicted fork bomb | |
170 | leading to an out-of-memory crash. | |
171 | ||
172 | E2fsprogs is now more portable to Solaris. | |
173 | * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's | |
174 | are always present. | |
175 | * Scripts do not assume that /bin/true is always in /bin | |
176 | * Don't use __FUNCTION__ since Solaris's C99 doesn't support it. | |
177 | * Flush stdio handles before calling setbuf(), since Solaris will | |
178 | discard any pending output to the stream. | |
179 | * Define _XOPEN_SOURCE to 600 since Solaris's header files are very | |
180 | picky about which C compiler can beused for SUSv3 conformance. | |
181 | Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500), | |
182 | and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600). | |
183 | Since we need some SUSv3 functions, consistently use SUSv3 so | |
184 | that e2fsprogs will build on Solaris using c99. | |
185 | * Solaris C99 does not support varargs C preprocessor macros | |
186 | * Solaris header files pollute the C namespace if in/netinet.h | |
187 | is included, which conflicts with e2fsprogs' use of the kmem_cache_t | |
188 | typedef. | |
189 | * Solaris ships with a pathetically ancient shell in /bin/sh so we | |
190 | avoid the use of various more avanced shell constructs such as $(). | |
191 | ||
192 | To support old GNU C compilers don't use C99/C++ comments, but only | |
193 | K&R style comments, and don't try to use __builtin_expect if __GNUC__ | |
194 | is less than 3. (__builtin_expect is only supported for gcc versions | |
195 | 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since | |
196 | this is an optimization, we only try to use __builtin_expect for gcc 3 | |
197 | and up.) | |
198 | ||
199 | In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of | |
200 | __LITTLE_ENDIAN, which are only defined by glibc's header files and | |
201 | hence isn't portable. | |
202 | ||
203 | For the convenience for some distributions that need a static tune2fs, | |
204 | the Makefile for misc/ now has a tune2fs.static target. | |
205 | ||

207 | E2fsprogs 1.41 (July 10, 2008) |
208 | ============================== | |
795de67f TT |
209 | |
210 | Add support for ext4 filesystem features, in particular extents, | |
211 | uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add | |
212 | support for checking journal checksums. Debugfs will print new | |
213 | superblock and inode fields that were defined for ext4. For example, | |
214 | the nanosecond and i_version fields of an inode, and the | |
215 | s_min_extra_isize and s_wanted_extra_isize fields from the superblock. | |
216 | Note: Resize2fs doesn't currently support the combination of flex_bg | |
217 | and !resize_inode. (Addresses Debian Bug: #388452, #425477) | |
218 | ||
219 | Tune2fs can support migrating a filesystem from using 128 byte inodes | |
220 | to 256 byte inodes, so it can take advantage of the full features of | |
221 | ext4. | |
222 | ||
223 | Add support for "undo" support. E2fsck and mke2fs can optionally | |
224 | record an undo log which can replayed by the program e2undo. | |
225 | ||
92e49d85 TT |
226 | E2fsck could damage a filesystem by trying to relocate inode tables |
227 | due to corrupted block group descriptors, where the attempted inode | |
228 | table relocation would do far more harm than good. E2fsck has been | |
229 | fixed to detect this these sorts of corrupted block group descriptors | |
230 | much earlier in e2fsck processing, so it can try to use the backup | |
231 | superblock and block group descriptors first. This should be a much | |
232 | better strategy for recovering these types of corrupted filesystems. | |
233 | (Addresses Sourceforge Bug: #1840291) | |
234 | ||
795de67f TT |
235 | E2fsck will display a more understandable message when the last check |
236 | field in the superblock is in the future. (Addresses Debian Bug: | |
237 | #446005). | |
238 | ||
92e49d85 TT |
239 | E2fsck now performs more extensive and careful checks of extended |
240 | attributes stored in the inode. | |
241 | ||
a41d5ac8 TT |
242 | Enhance mke2fs to print a more explanatory error message when |
243 | ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug: | |
244 | #488663) | |
245 | ||
246 | Fix mke2fs to use a default block size of 4k when formatting an | |
247 | external journal device. This is done by using a fixed filesystem | |
248 | type list that consists only of the single filesystem type "journal" | |
249 | when looking up configuration keys in /etc/mke2fs.conf. (Addresses | |
250 | Debian Bug: #488663) | |
251 | ||
795de67f TT |
252 | Speed up how mke2fs writes the journal data blocks by writing the disk |
253 | blocks in larger chunks. | |
254 | ||
a41d5ac8 TT |
255 | Fix blkid handling of stale devices. Fix a bug which could cause a |
256 | core dump while garbage collecting the blkid cache, and assure that | |
257 | blkid_find_dev_with_tag() never returns a non-existent device. Also, | |
258 | if a filesystem is found at a new /dev location, eliminate any | |
259 | duplicate stale entries which can not be verified. | |
260 | (Addresses-Debian-Bugs: #487758, #487783) | |
261 | ||
795de67f TT |
262 | Add more paranoid checks for LVM volumes and swap partitions in |
263 | blkid's probe function, to reduce the chances of false positives. | |
264 | ||
265 | The mke2fs program now has a much more sophisticated system for | |
266 | controlling configuration parameters of a newly created filesystem | |
267 | based on a split filesystem and usage type system. The -t option to | |
268 | mke2fs was a deprecated alias to -c; it now specifies a filesystem | |
269 | type (ext2, ext3, ext4, etc.), while the -T option can now be a comma | |
270 | separated usage list. The filesystem type information and type | |
271 | information is used to extract configuration parameters from the | |
272 | /etc/mke2fs.conf file. | |
273 | ||
795de67f TT |
274 | The mke2fs program will no longer complain and request the -f option |
275 | when the user tries to create a filesystem with greater than 2**31 | |
276 | blocks. | |
277 | ||
92e49d85 TT |
278 | When creating a filesystem for the GNU Hurd use a fs-type of Hurd and |
279 | adjust the mke2fs.conf file so filesystems for the Hurd are created | |
280 | with a blocksize of 4096 and inode size of 128, which is all it knows | |
281 | how to handle. (Addresses Debian Bug: #471977) | |
282 | ||
795de67f TT |
283 | Mke2fs will always make sure that lost+found always has at least 2 |
284 | blocks, even for filesystems with very large blocksizes (i.e., 64kb). | |
285 | ||
92e49d85 TT |
286 | Resize2fs will now print the minimum needed filesystem size if given |
287 | the -P option, and will resize the filesystem to the smallest possible | |
288 | size if given the -M option. | |
289 | ||
290 | Fix resize2fs to clean up the resize_inode if all of the reserved gdt | |
291 | blocks are consumed during an off-line resize. | |
292 | ||
795de67f TT |
293 | The "ls" command in debugfs now supports the -p option, which causes |
294 | it to quote the filenames so that spaces or tabs in directory entries | |
295 | are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses | |
296 | Sourceforge Feature Request: #1201667) | |
297 | ||
298 | Fix a potential off-by-one buffer oveflow in the fs_device_name in an | |
299 | e2image file. | |
300 | ||
301 | The chattr program will return a non-zero exit code in case of | |
302 | failures, and error messages can be suppressed with the -f option. | |
a41d5ac8 TT |
303 | (Addresses Red Hat Bugzilla: #180596) |
304 | ||
305 | Fix a bug in badblocks which caused it to overrun an array and likely | |
306 | crash if more than 8 test patterns are specified using the -t option. | |
307 | (Addresses Debian Bug: #487298) | |
795de67f | 308 | |
a41d5ac8 TT |
309 | Add support to badblocks to limit how quickly it reads from the disk |
310 | drive (so it can be used for background scrubbing), and so it will | |
311 | abort after finding a given number of errors. | |
312 | ||
795de67f TT |
313 | Remove support for the legacy big-endian filesystem format which only |
314 | existed on extremely long-dead PowerPC kernels almost a decade ago. | |
315 | ||
316 | Remove MASIX support from e2fsprogs. | |
317 | ||
318 | Add I/O statistics reporting to e2fsck. | |
319 | ||
a41d5ac8 TT |
320 | Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch, |
321 | Czech translations. | |
322 | ||
323 | Fixed various Debian packaging issues --- see debian/changelog for | |
92e49d85 | 324 | details. (Addresses Debian Bugs: #487443, #487675, #490003) |
a41d5ac8 TT |
325 | |
326 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
92e49d85 | 327 | (Addresses Debian Bugs: #393313, #487849, #440983, #440981) |

329 | Programmer's Notes |
330 | ------------------ | |
331 | ||
332 | Factor out bitmap code in preparation for adding 64-bit new-style | |
333 | bitmaps. | |
334 | ||
335 | Fix gcc -Wall warnings | |
336 | ||
337 | Fix the pkg-config files so that private librares are specified in | |
338 | "Libs.private:". | |
339 | ||
340 | Fix the libext2fs.texinfo manual so it builds with modern versions of | |
341 | texinfo. | |
342 | ||
343 | Silence the makefile from showing the awk command used to build the | |
344 | ||
345 | Clean up the badblocks group so to make it more portable and robust. | |
346 | ||
347 | Avoid using predictable filenames in /tmp in blkid's regression test | |
348 | suite. Also remove bashism's in the regression test script. | |
349 | ||
92e49d85 TT |
350 | If the configure script is given --with-diet-libc, don't use thread |
351 | local storage, since diet libc doesn't support TLS. (Addresses | |
352 | Sourceforge Bug: #2000654) | |
353 | ||
354 | Fix the blkid regression test suite to tolerate older versions of | |
355 | mkswap that don't support the -U option. | |
356 | ||
795de67f TT |
357 | A few library routines have been converted to support 64-bit block |
358 | numbers; in particular, the I/O manager functions, the test_io, | |
359 | inode_io, and unix_io managers have all be converted to support 64-bit | |
360 | operation. | |
361 | ||
362 | Debugfs can now be extended for use by test programs. See | |
363 | lib/ext2fs/extents.c for an example for how it can be used. The test | |
364 | program links against the debugfs object files, and provides | |
365 | additional commands by defining an auxiliary libss command table. | |
366 | ||
367 | The lazy_bg filesystem feature, which was only used by developer's | |
368 | testing, has been removed since it has been largely supplanted by | |
369 | uninit_bg. This also simplifies the code. | |
370 | ||
371 | ||
0c7be6cb TT |
372 | E2fsprogs 1.40.11 (June 17, 2008) |
373 | ================================= | |
374 | ||
375 | Mke2fs, tune2fs, and resize2fs now use floating point to calculate the | |
376 | percentage of reserved blocks. (Addresses Debian Bug: #452639) | |
377 | ||
378 | Updated Spanish and Catalan translations. | |
379 | ||
380 | Fixed various Debian packaging issues --- see debian/changelog for | |
381 | details. (Addresses Debian Bugs: #483962, #483023) | |
382 | ||
383 | Add detection for ZFS volumes to the libblkid library. | |
384 | ||
385 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
386 | (Addresses Debian Bug: #486463) | |
387 | ||
388 | Programmer's notes: | |
389 | ------------------- | |
390 | ||
391 | Fix marginal C code in probe_lvm2() function to the blkid library more | |
392 | portable for older compilers. | |
393 | ||
394 | Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473) | |
395 | ||
396 | Fix ext2fs_swap{16,32,64} functions so they can be used by external | |
397 | applications on big-endian machines. (Addresses Debian Bug: #484879) | |
398 | ||
399 | ||
491d8bc3 TT |
400 | E2fsprogs 1.40.10 (May 21, 2008) |
401 | ================================ | |
402 | ||
403 | When deciding whether or not to revalidate a blkid cache entry, if the | |
404 | device's mtime is newer than the last time the cached entry was | |
405 | validated, force a revalidation. | |
406 | ||
407 | Fix a potential data corruption bug in e2fsck in the journal replay. | |
408 | The chances of this is happening is extremely remote, especially the | |
409 | default data=ordered or data=writeback modes. However, if a block | |
410 | which has been journalled starts with the first four bytes 0xc03b3998, | |
411 | when e2fsck replays the journal, those four bytes will be replaced | |
412 | with zero's. Fortunately, it is highly, highly unlikely for e2fsck | |
413 | metadata to begin with those fatal 4 byte sequence, and unless | |
414 | data=ordered mode is in use, data blocks are never journaled. | |
415 | ||
416 | Updated German, Dutch, Sweedish, and Vietnamese translations. | |

420 | ||
421 | Fixed various Debian packaging issues --- see debian/changelog for | |

424 | Remove default sizes of types when cross compiling, since autoconf | |
425 | 2.50 can figure this out automatically now. | |

430 | |
431 | SuSE's security team audited uuidd and came up with a few minor | |
432 | issues. None of them are serious given that uuidd runs setuid as a | |
433 | unprivileged user which has no special access other than libuuid | |
434 | directory, but it's good to get them fixed. | |
435 | ||
436 | One additional fix in ext2fs_swap_inode_full() needed for resize2fs to | |
437 | work correctly with in-inode extended attributes. | |
438 | ||
7affded7 TT |
439 | Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese |
440 | translations. | |
441 | ||
442 | Debugfs will avoid using a pager if the standard output is not a tty. | |
443 | ||
444 | Fix debugfs and tune2fs to correctly handle daylight savings time when | |
445 | parsing a time string. | |
446 | ||
447 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
448 | ||
449 | Fix fsck completion bars when multiple filesystems were being checked | |
450 | in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug: | |
451 | #203323, Addresses Sourceforge Bug: #1926023) | |
452 | ||
453 | Fix fsck so that progress information is sent back correctly when | |
454 | multiple filesystems are being check and the output of fsck is being | |
455 | redirected to a file descriptor. Also, include the device name (w/o | |
456 | spaces) in the progress information sent back via a file descriptor. | |
457 | (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug: | |
458 | #1926023) | |
459 | ||
460 | Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems. | |
461 | ||
462 | If logsave receives a SIGTERM or SIGINT signal, it will now pass that | |
463 | signal to its child process. | |
464 | ||
465 | Fix mke2fs's creation of are resize inode when there is a non-standard | |
466 | s_first_data_block setting. | |
467 | ||
468 | Fix bug in blkid when run by an unprivileged user; most devices were | |
469 | not reported correctly. 9Addresses Launchpad Bug: #220275) | |
470 | ||
471 | Mke2fs will not allow the logically incorect combination of | |
472 | resize_inode and meta_bg, which had previously caused mke2fs to create | |
473 | a corrupt fileystem. | |
474 | ||
475 | Fix fsck in German locales so that a 'j' means yes. | |

498 | E2fsprogs 1.40.8 (March 13, 2008) |
499 | ================================= | |
500 | ||
501 | Fixed e2image -I so it works on image files which are larger than 2GB. | |
502 | ||
503 | Fixed e2fsck's handling of directory inodes with a corrupt size field. If | |
504 | the size is larger than the number of blocks found in the inode, don't | |
505 | try to allocate extra empty blocks at the end of the directory to make | |
506 | up the difference; there's no point to doing that. In addition, if | |
507 | the size is not a multiple of a blocksize, always fix it. | |
508 | ||
509 | E2fsck handled a pass 2 "should never happen error" by not giving | |
510 | enough information and then core dumping. Unfortunately, it was all | |
511 | too easy to trigger the "should never happen" situation if a | |
512 | directory's inode size was not correct. This has been fixed, but | |
513 | e2fsck has also been taught how to handle this situation more | |
514 | gracefully, by simply removing the inode hash tree information, so | |
515 | that it can be rebuilt again after e2fsck's pass 3. (Addresses | |
516 | Launchpad Bug: #129395) | |
517 | ||
518 | Resize2fs had a bug resizing large inodes with extended attributes | |
519 | that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed | |
520 | completely on big-endian systems such as PowerPC. The bug should be | |
521 | completely fixed now. Yay for regression test suites. (Addresses Red | |
522 | Hat Bugzilla: #434893) | |
523 | ||
524 | Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese | |
525 | translations. Many thanks to Philipp Thomas from Novell for stepping | |
526 | up to become the new German translation maintainer! (Addresses Debian | |
527 | Bugs: #302512, #370247, #401092, #412882). | |
528 | ||
529 | When e2fsck is clearing a corrupt inode's HTREE directory information, | |
530 | make it clear that it is just clearing the HTREE information, not the | |
531 | entire inode. | |
532 | ||
533 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
534 | ||
535 | Programmer's notes | |
536 | ------------------ | |
537 | ||
538 | Add new functions, ext2fs_dblist_get_last() and | |
539 | ext2fs_dblist_drop_last(), which allows the caller to examine the last | |
540 | directory block entry added to the list, and to drop if it necessary. | |
541 | ||
542 | Fixed a portability problem in libblkid with DJGPP. | |
543 | ||
544 | Fix an obvious typo in an "internal error" message in e2fsck. Thanks | |
545 | to Philipp Thomas for pointing this out. | |
546 | ||
547 | If the info files are not built, change "make install" so it doesn't | |
548 | fail with an error code. | |

551 | E2fsprogs 1.40.7 (February 28, 2008) |
552 | ==================================== | |
553 | ||
554 | Remove support for clearing the SPARSE_SUPER feature from tune2fs, and | |
555 | depreciate the -s option, since it can result in filesystems which | |
556 | e2fsck can't fix easily. There are very good reasons for wanting to | |
557 | disable sparse_super; users who wants to turn off sparse_super can use | |
558 | debugfs. (Addresses Sourceforge Bug: #1840286) | |
559 | ||
560 | Add missing options to mke2fs's usage message. (Addresses Sourceforge | |
561 | Bug: #1751393) | |
562 | ||
563 | Fix bug in resize2fs when large (greater than 128 byte) inodes are | |
564 | moved when a filesystem is shrunk; it was only moving the first 128 | |
565 | bytes, so extended attributes were not getting moved. (Addresses Red | |
566 | Hat Bugzilla: #434893) | |
567 | ||
568 | E2fsck now prints an explicit message when the bad block inode is | |
569 | updated, to avoid confusion about why the filesystem was modified. | |
570 | (Addresses Sourceforge Bug: #756460) | |
571 | ||
572 | Allow mke2fs and tune2fs manipulate the large_file feature. | |
573 | Previously we just let the kernel and e2fsck do this automatically, | |
574 | but e2fsck will no longer automatically clear the large_file feature. | |
575 | It still isn't really necessary to worry about this feature flag | |
576 | explicitly, but some users seem to care. (Addresses Red Hat Bugzilla: | |
577 | #258381) | |
578 | ||
579 | Suppress message about an old-style fstab if the fstab file is empty. | |
580 | (Addresses Debian Bug: #468176) | |
581 | ||
582 | Fix (really minor) bug in debugfs's find_free_block so it avoids | |
583 | reporting a free block more than once if there are too few free blocks | |
584 | in the filesystem. (Addresses Sourceforge Bug: #1096315) | |
585 | ||
586 | Change e2fsck to no longer clear the LARGE_FILES feature flag | |
587 | automatically, when there are no more > 2GB files in the filesystem. | |
588 | It's been almost a decade since there have been kernels that don't | |
589 | support this flag, and e2fsck clears it quietly without telling the | |
590 | user why the filesystem has been changed. | |
591 | ||
592 | Fix bug which could cause libblkid to seg fault if a device mapper | |
593 | volume disappears while it is being probed. (Addresses RedHat | |
594 | Bugzilla: #433857) | |
595 | ||
596 | Inhance e2fsck's reporting of unsupported filesystem feature flags. | |
597 | (Addresses Sourceforge Feature Request: #1175808) | |
598 | ||
599 | Fix option syntax in dumpe2fs for explicit superblock and blocksize | |
600 | parameters. What was currently documented in the man page has been | |
601 | broken for some time, due to getopt() implementation changes. The | |
602 | option sytax has been changed to one which is can be more portable | |
603 | supported and which is consistent with the format for extended options | |
604 | in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994) | |
605 | ||
606 | Add support to tune2fs to clear the resize_inode feature. This | |
607 | requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816) | |
608 | ||
609 | Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat | |
610 | Bugzilla: #409321) | |
611 | ||
612 | Add support for setting RAID stride and stripe-width via mke2fs and | |
613 | tune2fs. Teach dumpe2fs to print the RAID parameters. | |
614 | ||
615 | Add support for setting new superblock fields to debugfs's | |
616 | set_super_value. | |
617 | ||
618 | Add support for printing "mostly-printable" extended attributes in | |
619 | Debugfs. | |
620 | ||
621 | Add support for the -M option to fsck, which causes it to ignore | |
622 | mounted filesystem. | |
623 | ||
624 | Fix uuidd so that it creates the pid file with the correct pid number. | |
625 | (Addresses Sourceforge Bug: #1893244) | |
626 | ||
627 | Fix various gcc -Wall warnings. | |
628 | ||
629 | Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations | |

638 | Fixed various Debian packaging issues --- see debian/changelog for | |

640 | ||
641 | Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a | |
642 | partially filled-in filesystem object on an error, so that e2fsck can | |
643 | print more intelligent error messages. | |
644 | ||
645 | Add a new function e2p_edit_feature2() which allows the caller to | |
646 | specify which feature flags are OK to set or clear, and which returns | |
647 | more specific information about feature flags which are not allowed to | |
648 | be set/cleared. | |
649 | ||
650 | Set the C locale in the test_script driver since it uses [A-Za-z]. | |
651 | (Addresses Sourceforge Bug: #1890526) | |
652 | ||
653 | Use fcntl locking instead of lockf in libuuid since Cygwin doesn't | |
654 | support lockf(). | |
655 | ||
656 | Change configure.in to avoid using the 'dc' command unless it is | |
657 | absolutely needed. (i.e., when using parsing a WIP-style version | |
658 | number) (Addresses Sourceforge Bug: #1893024) | |
659 | ||
660 | Add portability checks to support compilation under DJGPP. | |
661 | ||
662 | Update to the latest samba tdb code before the LGPLv3 change, which | |
663 | fixes a realloc() leak on failure. | |
664 | ||
665 | Fix memory leak in ext2fs_alloc_block(). | |
666 | ||
667 | Fix makefile dependency issues for various install targets. | |
668 | (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456) | |

676 | Add support for returning labels for UDF filesystems in the blkid | |
677 | library. | |
678 | ||
679 | Fix bug in the blkid library where cached filesystems was not being | |
680 | flushed when opening USB devices returned the error ENOMEDIUM. | |
681 | (Addresses Debian Bug: #463787) | |
682 | ||
683 | Added logic to the blkid library to automatically choose whether a | |
684 | filesystem should be mounted as ext4 or ext4dev, as appropriate. | |
685 | ||
686 | Allow tune2fs to set and clear the test_fs flag on ext4 filesystems. | |
687 | ||
688 | Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been | |
689 | configured with --enable-jbd-debug. | |
690 | ||
691 | Document the BLKID_FILE environment variable in the libblkid man page | |

710 | E2fsprogs 1.40.5 (January 27, 2008) |
711 | =================================== | |
712 | ||
713 | Fix a potential overflow big in e2image if the device name is too | |
714 | long. | |
715 | ||
716 | Mke2fs will now create new filesystems with 256 byte inodes and the | |
717 | ext_attr feature flag by default. This allows for much better future | |
718 | compatibity with ext4 and speeds up extended attributes even on ext3 | |
719 | filesystems. | |
720 | ||
721 | Teach e2fsck to ignore certain "safe" filesystem features which are | |
722 | set automatically by the kernel. Having the kernel set features | |
723 | automagically behind the user's back is a bad idea, and we should try | |
724 | to break the kernel of this habit, especially for the newer ext4 | |
725 | feature flags. But for now, we will try to avoid needless full checks | |
726 | which can annoy users who are doing fresh installs. | |
727 | ||
728 | Add support in tune2fs and mke2fs for making a filesystem as being "ok | |
729 | to be used with test kernel code". This will be needed for using test | |
730 | filesystems with the latest ext4 kernel code. | |
731 | ||
732 | Change e2fsck -fD so that it sorts non-htree directories by inode | |
733 | numbers instead of by name, since that optimizes performances much | |
734 | more significantly. (Addresses-Sourceforge-Feature-Request: #532439) | |
735 | ||
736 | If e2image fills the disk, fix it so it exits right away instead of | |
737 | spewing large numbers of error messages. | |
738 | (Addresses-Sourceforge-Feature-Request: #606508) | |
739 | ||
740 | If ftruncate64() is not available for resize2fs, let it use ftrucate() | |
741 | instead, but have it check to see if the size would get truncated, and | |
742 | skip calling ftruncate in that case. | |
743 | ||
744 | Add support for detecting HFS+ filesystems in the blkid library. | |
745 | ||
746 | Add supprt in the blkid library for ext4/ext4dev filesystems. | |
747 | ||
748 | Fix a bug in blkid where it could die on a floating point exception | |
749 | when presented with a corrupt reiserfs image. | |
750 | ||
751 | Fix blkid's handling of ntfs UUID's so that leading zeros are printed | |
752 | such that UUID string is a fixed length. | |
753 | ||
754 | Add sample python bindings for the uuid library to the contrib | |
755 | directory. (Addresses-Sourceforge-Patches: #778817) | |
756 | ||
757 | Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it | |
758 | will work with large files. (Addresses Sourceforge Feature Request: | |
759 | #1257500 and Sourceforge Support Request: #1253511) | |
760 | ||
761 | Allow the debugfs 'undel' command to undelete an inode without linking | |
762 | it to a specific destination directory, since this might require | |
763 | allocating blocks that could overwrite some yet-to-be-recovered | |
764 | deleted files. (Addresses-Sourceforge-Feature-Request: #967141) | |

801 | ||
802 | Improve time-based UUID generation. A new daemon uuidd, is started | |
803 | automatically by libuuid if necessary. This daemon is setuid to allow | |
804 | updates to /var/lib/libuuid, so the clock sequence number can be | |
805 | stored and so if the clock is set backwards, it can be detected. | |
806 | (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla: | |
807 | #233471) | |
808 | ||
809 | Filter out the NEEDS_RECOVERY feature flag when writing out the backup | |
810 | superblocks. This avoids e2fsck from concluding that a full | |
811 | filesystem check is required before backing up the superblock due to | |
812 | changes in the feature flags. (Addresses Debian Bug: #454926) | |
813 | ||
814 | Fix fsck to only treat the '#' character as a comment at the beginning | |
815 | of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem | |
816 | will cause fsck to issue an bogus warning message. | |
817 | (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147) | |
818 | ||
819 | Format control characters and characters with the high eighth bit set | |
820 | when printing the contents of the blkid cache, to prevent filesystems | |
821 | with garbage labels from sending escape sequences to the user's screen | |
822 | that might, for example place it in graphics mode. (Addresses Ubuntu | |

854 | E2fsprogs 1.40.3 (December 5, 2007) |
855 | =================================== | |
856 | ||
857 | Fix a potential security vulnerability where an untrusted filesystem | |
858 | can be corrupted in such a way that a program using libext2fs will | |
859 | allocate a buffer which is far too small. This can lead to either a | |
860 | crash or potentially a heap-based buffer overflow crash. No known | |
861 | exploits exist, but main concern is where an untrusted user who | |
862 | possesses privileged access in a guest Xen environment could corrupt a | |
863 | filesystem which is then accessed by the pygrub program, running as | |
864 | root in the dom0 host environment, thus allowing the untrusted user to | |
865 | gain privileged access in the host OS. Thanks to the McAfee AVERT | |
866 | Research group for reporting this issue. (Addresses CVE-2007-5497.) | |
867 | ||
868 | Fix hueristics in blkid which could cause a disk without partitions to | |
869 | be incorrectly skipped when a loopback device is present. (Addresses | |
870 | Red Hat Bugzilla #400321.) | |
871 | ||
872 | Fix e2image so that in raw mode it does not create an image file which | |
873 | is one byte too large. | |
874 | ||
875 | Change mke2fs's usage message so it recommends the preferred -E option | |
876 | instead of the deprecated -R option. | |
877 | ||
878 | Enhance the blkid library so it will recognize squashfs filesystems. | |
879 | (Addresses Red Hat Bugzilla #305151.) | |
880 | ||
881 | Enhance e2fsck so it will force the backup superblocks to be backed up | |
882 | if the filesystem is consistent and key constants have been changed | |
883 | (i.e., by an on-line resize) or by e2fsck in the course of its | |
884 | operations. | |
885 | ||
886 | Enhance blkid's detection of FAT filesystems; so that USB disks with | |
887 | only a single bootable partition will not get missed. | |
888 | ||
889 | E2fsck will no longer mark a filesystem as invalid if it has time | |
890 | errors (i.e., if superblock mount time or last write time is in the | |
891 | future) and the user refuses to fix the problem. | |
892 | ||
893 | The Ubuntu init scripts don't properly set the system time correctly | |
894 | from hardware clock if the hardware clock is configured to tick local | |
895 | time instead of GMT time. Work around this as best as we can by | |
896 | providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can | |
897 | be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu | |
898 | Bug #131201.) | |
899 | ||
900 | Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red | |
901 | Hat Bugzilla #151533.) | |
902 | ||
903 | Fix e2fsck so that if the superblock is corrupt, but still looks | |
904 | vaguely like an ext2/3/4 superblock, that it automatically tries to | |
905 | fall back to the backup superblock, instead of failing with a hard | |
906 | error. | |
907 | ||
908 | Make the e2fsprogs program more robust so that they will not crash | |
909 | when opening a corrupt filesystem where s_inode_size is zero. | |
910 | ||
911 | Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric | |
912 | arguments are detected as such and the parse error is reported to the | |
913 | user. (Addresses Debian Bug #435381.) | |
914 | ||
915 | Change e2fsck so it will not complain if a file has blocks reallocated | |
916 | up to the next multiple of a system's page size. | |
917 | ||
918 | Fix bug in ext2fs_check_desc() which will cause e2fsck to complain | |
919 | about (valid) filesystems where the inode table extends to the last | |
920 | block of the block group. (Addresses Red Hat Bugzilla #214765.) | |
921 | ||
922 | Fix a bug in ext2fs_initialize() which causes mke2fs to fail while | |
923 | allocating inode tables for some relatively rare odd disk sizes. | |
924 | (Addresses Red Hat Bugzilla #241767.) | |
925 | ||
926 | Add Catalan translation and update Dutch and Swedish translations | |
927 | from the Translation Project. | |
928 | ||
929 | Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We | |
930 | still had an issue when trying to figure out whether we need to | |
931 | byte-swap fast symlinks that contained extended attributes. | |
932 | ||
933 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
934 | (Addresses SourceForge Bug #1821333.) | |
935 | ||
936 | ||
937 | Programmer's Notes: | |
938 | ------------------- | |
939 | ||
940 | Fix mke2fs tests to avoid needing any significant ^M (CR) characters | |
941 | ||
942 | Add "make check" to the RPM spec file | |
943 | ||
944 | Fix "make install" and 'make unstall" in misc/Makefile.in so that it | |
945 | works correctly when the prefix is not the root directory. | |
946 | ||
947 | Fix the resize2fs tests, r_move_itable and r_resize_inode, so they | |
948 | clena up after themselves by deleting the test.img temporary file | |
949 | after completing the test. | |
950 | ||
951 | Fixed a corner case bug ext2fs_unlink() when trying to delete the | |
952 | first directory entry in a directory block and the last directory | |
953 | entry in the previous directory block is not in use. Fortunately | |
954 | ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in | |
955 | places where it is extremely unlikely to run into this corner case. | |
956 | ||
957 | Fix missing dependency which would cuase parallel builds to fail. | |
958 | (Addresses Sourceforge Bug #1842331.) | |
959 | ||
960 | Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c | |
961 | calling open(O_CREATE) with a missing mode parameter. | |
962 | ||
963 | Fix the test_ss.c in lib/ss so it can be used as an example | |
964 | application program for the library as well as a regression test | |
965 | suite. | |
966 | ||
967 | Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes | |
968 | are properly passed back up through the call stack. | |

970 | E2fsprogs 1.40.2 (July 12, 2007) |
971 | ================================ | |
972 | ||
973 | A recent change to e2fsck_add_dir_info() to use tdb files to check | |
974 | filesystems with a very large number of filesystems had a typo which | |
975 | caused us to resize the wrong data structure. This would cause a | |
976 | array overrun leading to malloc pointer corruptions and segfaults. | |
977 | Since we normally can very accurately predict how big the the dirinfo | |
978 | array needs to be, this bug only got triggered on very badly corrupted | |
979 | filesystems. | |
980 | ||
981 | Fix a bug in e2fsck which caused it to incorrectly salvange | |
982 | directories when the last entry's rec_len is bogusly too big. This | |
983 | resulted in a nonsense filesystem corruption to be reported, and | |
984 | required a second run of e2fsck to fully fix up the directory. | |
985 | ||
986 | Update tune2fs man page to include more discussion of reserved blocks | |
987 | (Addresses Launchpad bug #47817) | |
988 | ||
989 | Update Turkish, Polish, Dutch, and Vietnamese PO files from the | |
990 | Translation Project | |
991 | ||
992 | ||

993 | E2fsprogs 1.40.1 (July 7, 2007) |
994 | =============================== | |
58b3df7e TT |
995 | |
996 | Fix bug which could cause libblkid to loop forever. When revalidating | |
997 | a partition where there is obsolete information in /etc/blkid.tab, we | |
998 | end up freeing a the type tag without clearing dev->bid_type, causing | |
999 | blkid_verify() to loop forever. (Addresses Debian Bug: #432052) | |
1000 | ||
1001 | The Turkish translation has a bug in it where it has the translation | |
1002 | of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at | |
1003 | @E, recursively, forever, until the stack fills up and e2fsck core | |
1004 | dumps. We fix this by making e2fsck stop @-expansions after a | |
1005 | recursive depth of 10, which is far more than we need. | |
d2dc78ae | 1006 | (Addresses Sourceforge Bug: #1646081) |
58b3df7e TT |
1007 | |
1008 | Compile the default mke2fs.conf into mke2fs program. People are | |
1009 | getting surprised by mke2fs creating filesystems with different | |
1010 | defaults than earlier versions of mke2fs if mke2fs.conf is not | |
1011 | present. So we now create a built in version of mke2fs.conf file | |
1012 | which is used by mke2fs if the /etc/mke2fs.conf is not present. | |
1013 | (Addresses SourceforgeBug: #1745818) | |
1014 | ||
1015 | Improve the config/parse_types.sh helper script. Fix a potential | |
1016 | security problem if e2fsprogs is built as root (as Gentoo does!). In | |
1017 | addition fix the script and how it is called from the configure script | |
1018 | so that it does the right thing when cross-compiling. (Fixes Gentoo | |
1019 | bug: #146903) | |
1020 | ||
1021 | Update Vietnamese, French, and Dutch PO files from the Translation | |
1022 | Project. Also created a new e2fsprogs.pot file for translator. | |
1023 | ||
1024 | Fix bogus strip permission errors when building under Debian. When | |
1025 | building the e2fsprogs dpkg's, the dh_strip command emits a large | |
1026 | number of error messages caused by the permissions not being right. | |
1027 | So run dh_fixperms before running dh_strip. | |
58b3df7e TT |
1028 | |
1029 | Programmer's Notes: | |
1030 | ------------------- | |
1031 | ||
1032 | Add new function: profile_set_default(). This function sets the value | |
1033 | of the pseudo file "<default>". If the file "<default>" had | |
1034 | previously been passed to profile_init(), then def_string parameter | |
1035 | will be parsed and used as the profile information for the "<default>" | |
1036 | file. | |
1037 | ||
1038 | Fix mk_cmds's error reporting so that it is unambiguous that it is the | |
1039 | mk_cmds script which is generating the error. (Obviates Gentoo patch: | |
1040 | e2fsprogs-1.32-mk_cmds-cosmetic.patch) | |
1041 | ||
1042 | Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high | |
1043 | priority" environment variable that overrides all others, where as | |
1044 | LANG is the lowest priorty environment variable. If LC_ALL is set, it | |
1045 | doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and | |
1046 | the all the rest are set. This will assure that the locale when | |
1047 | running the test suites is the "C" locale. (Obviates Gentoo patch: | |
1048 | e2fsprogs-1.38-tests-locale.patch) | |
1049 | ||

1051 | E2fsprogs 1.40 (June 29, 2007) |
1052 | ============================== | |
1053 | ||
1054 | Fix divide by zero error in blkid's NTFS probing logic. | |
d7b64725 TT |
1055 | |
1056 | Add new blkid -g option which causes the blkid cache to be garbage | |
1057 | collected. | |
1058 | ||
1059 | Fix a bug in libblkid which could cause the internal field bid_type to | |
1060 | become corrupted. Fortunately bid_type isn't used much, and bid_label | |
1061 | and bid_uuid is only used by debugging code, so the impact of this bug | |
1062 | was very minor. | |
1063 | ||
1064 | Mke2fs will now store the RAID stride value when a filesystem is | |
1065 | created with a requested RAID stride, and then use it automatically in | |
1066 | resize2fs. | |
1067 | ||
1068 | Mke2fs has a sanity check added to make sure (inode_size * num_inodes) | |
1069 | isn't too big. In some cases Lustre users have tried specifying an | |
1070 | inode size of 4096 bytes, while keeping an inode ratio of one inode | |
1071 | per 4096 bytes. | |
1072 | ||
1073 | Improve sanity check in e2fsck's algorithm for finding a backup | |
1074 | superblock, so that it won't accidentally find a superblock that was | |
1075 | located in the journal, and then later reject it as being not a valid | |
1076 | backup superblock. | |
1077 | ||
1078 | Fix e2fsck get_size logic so that it will work with the Linux floppy | |
1079 | driver. The Linux floppy driver is a bit different from the other | |
1080 | block device drivers, in that if the device has been opened with | |
1081 | O_EXCL, it disallows another open(), even if the second open() does | |
1082 | not have the O_EXCL flag. (Addresses Debian Bug: #410569) | |
1083 | ||
1084 | Fix error checking of badblock's last-block and start-block arguments. | |
1085 | (Addresses Debian Bug: #416477) | |
1086 | ||
1087 | Fix e2fsck so that it doesn't overwrite the backup superblocks when | |
1088 | recovering a journal until the master superblock has been confirmed as | |
1089 | being sane. | |
1090 | ||
1091 | Change the blkid library to be much more paranoid about concluding | |
1092 | that a partition contains an NTFS filesystem, and fetch the UUID and | |
1093 | LABEL information from NTFS filesystems. (Addresses Launchpad Bug: | |
1094 | #110138) | |
1095 | ||
1096 | Factor out the code which sets the default journal size and move it | |
1097 | into libext2fs. | |
1098 | ||
1099 | Enhance e2fsck so it will recreate the ext3 journal if the original | |
1100 | journal inode was cleared to due it being corrupt after finishing the | |
1101 | filesystem check. | |
1102 | ||
1103 | Fix e2fsck so that it updates the journal inode if it is corrupted and | |
1104 | the backup journal information from the superblock was successfully | |
1105 | used to recover the filesystem. | |
1106 | ||
1107 | Fix e2fsck so that it checks all of the blocks in the journal inode | |
1108 | for validity. The original code only checked the direct blocks to | |
1109 | make sure the journal inode was sane. Unfortunately, if some or all | |
1110 | of the indirect or doubly indirect blocks were corrupted, this would | |
1111 | not be caught. | |
1112 | ||
1113 | Add support in blkid to detect LUKS encrypted partitions. | |
1114 | ||
1115 | Add extra sanity checks for extended attributes in the case where the | |
1116 | size is zero but the offset is very large. | |
1117 | ||
1118 | Fix byte-swapping issues for large inodes in ext2fs_read_inode_full() | |
1119 | and ext2fs_get_next_inode_full(). | |
1120 | ||
1121 | Clarify the copyright licenses used by the various libraries in | |
1122 | the top-level COPYING file (Red Hat Bugzilla: 166058) | |
1123 | ||
1124 | Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane. | |
1125 | ||
1126 | Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's. | |
1127 | ||
1128 | Remove check in e2fsck which requires EA's in inodes to be sorted; | |
1129 | they don't need to be sorted, and e2fsck was previously wrongly | |
1130 | clearing unsorted EA's stored in the inode structure. | |
1131 | ||
1132 | Allow mke2fs or tune2fs to create a substantially larger journal (up | |
1133 | to 10,240,000 blocks). | |
1134 | ||
1135 | Fix MD superblock detection, and make sure the correct UUID is | |
1136 | reported from the MD superblock. | |
1137 | ||
1138 | Fix a signed vs. unsigned bug in debugfs. | |
1139 | ||
1140 | Enhance debugfs's date parser so that it accepts integer values. | |
1141 | ||
1142 | Fix e2fsck's pass1c accounting so it doesn't terminate too early if a | |
1143 | file with multiply claimed blocks is hard linked. or not at all if the | |
1144 | root directory contains shared blocks | |
1145 | ||
1146 | Enhance debugfs so it can modify the block group descriptors using the | |
1147 | command set_block_group_descriptor. | |
1148 | ||
1149 | Improve e2fsck's reporting of I/O errors so it's clearer what it was | |
1150 | trying to do when an error happens | |
1151 | ||
1152 | Fix a bug in in how e2fsprogs byte swaps inodes containing fast | |
1153 | symlinks that have extended attributes. (Addresses Red Hat Bugzilla: | |
1154 | #232663 and LTC Bugzilla: #27634) | |

1156 | Fix potential file descriptor leak in ext2fs_get_device_size() in an | |
1157 | error case. | |

1162 | ||
1163 | Fix dump_unused segfault in debugfs when a filesystem is not open | |
1164 | ||
1165 | Fix memory leak in blkid library. (Addresses Debian Bug: #413661) | |

1167 | Allow the debugfs lcd command to work w/o a filesystem being open. | |
1168 | (Addresses LTC Bugzilla #27513) | |
1169 | ||
1170 | Fix e2fsck to clear i_size for special devices with a bogus i_blocks | |
1171 | field on the first pass. | |
1172 | ||
1173 | Fix e2fsck to set the file type of the '..' entry when connecting | |
1174 | a directory to lost+found. (Addresses Lustre Bug: #11645) | |
1175 | ||
1176 | Enhance e2fsck to recover directories whose modes field were corrupted | |
1177 | to look like special files. This is probably only useful in | |
1178 | artificial test cases, but it will be useful if we ever do the "inodes | |
1179 | in directory" idea for ext4. | |
1180 | ||
1181 | Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug: | |
1182 | #412614) | |
1183 | ||
1184 | Fix resize2fs parsing of size parameter (in sector units). This was | |
1185 | actually a bug in libe2p's parse_num_blocks() function. When handling | |
1186 | the 's' suffix, it was ignoring the blocksize information passed in | |
1187 | from the caller and always interpreting the number in terms of a 1k | |
1188 | blocksize. (Addresses Debian Bug: #408298) | |
1189 | ||
1190 | There was a floating point precision error which could cause e2fsck to | |
1191 | loop forever on really big filesystems with a large inode count. | |

1196 | Add support for using a scratch files directory to reduce e2fsck's | |
1197 | emory utilization on really big filesystems. This uses the TDB | |
1198 | library. See the [scratch_files] section of the e2fsck.conf man page | |

1206 | ||
1207 | Allow debugfs and dumpe2fs to support fs features under development. | |
1208 | ||
1209 | Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to | |
1210 | ext2fs_open() , which allows application to open filesystes with features | |
1211 | which are currently only partially supported by e2fsprogs. | |

1216 | Fixed overflow and signed/unsigned problems caused by the number of | |
7809bc56 TT |
1217 | blocks or inodes exceeding 2**31 or being close to 2**32-1. |
1218 | ||
1219 | Add support for unsigned directory hash calculations with hints in the | |

1224 | Fix resize2fs so that it gives user-intelligible error messages if the | |
1225 | filesystem or the kernel does not support on-line resizing. | |
1226 | (Addresses Debian Bug: #380548) | |
1227 | ||
1228 | Require mke2fs -F -F for really dangerous operations, since -F is | |
1229 | needed for less dangerous operations such as creating filesystems | |
1230 | images in regular files, or creating filesystems on whole block | |
1231 | devices. These relatively innocuous usages should NOT be confused | |
1232 | with running mke2fs on an apparently-mounted or in-use filesystem. | |
1233 | ||
1234 | Allow the default inode size to be specified into the mke2fs.conf | |
1235 | file. | |
1236 | ||
1237 | Make the smallest default journal size is big enough so that on-line | |
1238 | resizing should always work. | |

1252 | pathnames had an extra "/dev" when they were being probed. | |
1253 | ||
1254 | Add GFS/GFS2 support to the blkid library. | |
1255 | ||
1256 | Fix blkid support of empty FAT filesystem labels. | |
1257 | ||
1258 | Avoid recursing forever (or for a long time) when the blkid library | |
1259 | searches for a device and there are symlinks to directories in /dev. | |
1260 | ||
1261 | Avoid unaligned halfword access in blkid when accessing FAT | |
1262 | superblocks, as this will cause Sparc/Solaris systems to throw a | |
1263 | SIGBUS error. | |
1264 | ||
1265 | The latest devmapper libraries requires pthreads, add -lpthreads to | |
1266 | the static link libraries for e2fsck.static if devmapper is enabled. | |
1267 | (Addresses Debian bug: #388718) | |
1268 | ||
1269 | Improve the (non-installed, for experts only) findsuper program by | |
1270 | printing the uuid and label from the superblocks, as well as the | |
1271 | starting and ending offsets of the filesystem given the information in | |
1272 | the superblock. Omit by default printing superblocks that are likely | |
1273 | found in located in an ext3 journal unless an explicit -j option is | |
1274 | given. | |
1275 | ||

1276 | Updated Spanish, French and Dutch translations and added Catalan |
1277 | translation. (Addresses Debian bug: #411562) | |

1278 | |
1279 | Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when | |
1280 | determining a partition's size, since binary searching to determine | |
1281 | the device doesn't work on FreeBSD. | |
1282 | ||
d7b64725 TT |
1283 | Documentation about UUID's is available in enough places, and it's |
1284 | awkward to deal with debian-legal's insanities. So I'm caving in the | |
1285 | "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we | |
1286 | don't have do the dfsg tarball. Also remove the rule that only tried | |
1287 | to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch | |
1288 | e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107) | |
1289 | ||
1290 | Fix the info-dir line so that the menu name does not contain a .info | |
1291 | prefix. First of all, it's ugly, secondly, it causes the install-info | |
1292 | command to fail to remove the com_err info file from the | |
1293 | /usr/share/info/dir file when the comerr-dev package is removed and | |
1294 | purged. (Addresses Debian Bug: #401711) | |

1304 | Programmer's notes: | |
1305 | ------------------- | |
1306 | ||
a0d42548 TT |
1307 | E2fsck now supports the %It expansion when printing a problem report. |
1308 | It will print the type of the inode in the problem context. | |
1309 | ||
26bcc2ca TT |
1310 | Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet |
1311 | (Addresses Sourceforge Bug: #1565561) | |
1312 | ||
1313 | Remove unused variables and other lint/gcc -Wall cleanups | |
1314 | ||
1315 | Add check to ext2fs_get_device_size() so it will return EFBIG for for | |
1316 | filesystems contained in regular files where the filesystem image size | |
1317 | is returned by stat64(). | |
1318 | ||
7809bc56 TT |
1319 | Set local environment variables to C so mk_cmds and compile_et always |
1320 | work. (Addresses SourceForge Bug: #1532177) | |
1321 | ||
26bcc2ca TT |
1322 | Added the 64-bit byte swapping function ext2fs_swab64(). |
1323 | ||
1324 | Added two new helper functions to prevent 2**31/2**32-1 overflow | |
1325 | problems: ext2fs_div_ceil() and e2p_percent(). | |
1326 | ||
1327 | Create new ext2fs library inline functions ext2fs_group_first_block() | |
1328 | and ext2fs_group_last_block() in order to calculate the starting and | |
1329 | ending blocks in a block group. | |
1330 | ||
1331 | Create the generated files read-only to remind developers not to edit them. | |
1332 | ||
7809bc56 TT |
1333 | Add support for autoconf 2.60 (with backwards compatibility for older |
1334 | versions of autoconf). | |
1335 | ||
26bcc2ca TT |
1336 | Added an "make rpm" target to top-level Makefile |
1337 | ||
1338 | Added various FreeBSD portability fixes. | |
1339 | ||
1340 | Exclude mercurial files from the RPM build tree to speed up copy/build. | |
1341 | ||
1342 | Use root_sysconfdir to define the locations of mke2fs.conf and | |
1343 | e2fsck.conf instead of using a hard-coded /etc pathname. | |
1344 | ||
1345 | Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times. | |
1346 | ||
1347 | Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files. | |
1348 | ||
1349 | If diff -u is supported, use it to report test failures. | |
1350 | ||
1351 | Updates/improvements to RPM spec file | |
1352 | ||
7809bc56 TT |
1353 | Add on-disk format definitions for the following new features: |
1354 | EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM, | |
1355 | EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT, | |
1356 | EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE | |
1357 | ||
1358 | Add a new make target "checked-failed" in the tests directory which | |
1359 | reruns any failed tests | |
1360 | ||
1361 | Update draft-leach-uuids-guids-01.txt with rfc4122.txt | |
1362 | ||
a0d42548 TT |
1363 | Fix miscellaneous bugs reported by Coverity: Dead code, potential nul |
1364 | pointer dereferences, memory leaks, etc. None were security-criticial | |
1365 | problems. | |
1366 | ||
1367 | Fix up usage and decrement error messages in the test_icount program | |
1368 | ||
1369 | Add debugging code to the com_err library; if the environment variable | |
1370 | COMERR_DEBUG is set to 1, print out debugging messages as error tables | |
1371 | are added and removed from the com_err library. If the | |
1372 | COMERR_DEBUG_FILE environment variable is set (and the process is not | |
1373 | setuid) the debugging messages may be redirected to a file. | |
1374 | ||
1375 | Change all of the e2fsprogs programs to use the newer add_error_table() | |
1376 | and remove_error_table() interfaces instead of the much older | |
1377 | initialize_*_error_table() function. | |
1378 | ||
1379 | Add TDB support into the ext2fs library. This allows us to have a | |
1380 | guaranteed library we can count on always being present so we can | |
1381 | store data in an on-disk database. | |
1382 | ||
1383 | Add support for using TDB to store the icount data, so we don't run out | |
1384 | of memory when checking really large filesystems. | |
1385 | ||
d7b64725 TT |
1386 | Change the regression test suite so that it skips empty test directories. |
1387 | ||
1388 | Define the l_i_iversion field in ext2_inode. The l_i_version field is | |
1389 | now defined from the old l_i_reserved1 field in the ext2 inode. This | |
1390 | field will be used to store high 32 bits of the 64-bit inode version | |
1391 | number. | |
1392 | ||
1393 | Add Makefile production rule for e2fsprogs.spec in case it gets | |
1394 | deleted. | |
1395 | ||
1396 | Add new function profile_get_uint() to allow for a clean way to fetch | |
1397 | unsigned integers from the context. | |
1398 | ||
1399 | Add test to make sure the ext2 superblock structure is 1024 bytes. | |
1400 | ||
1401 | Fix typo in name of f_dup4 regression test | |
1402 | ||
1403 | Add new function blkid_gc_cache() which performs a garbage collection | |
1404 | pass on the /etc/blkid.tab file. | |
1405 | ||
1406 | The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In | |
1407 | general, only e2fsck (after the filesystem is clean), tune2fs, and | |
1408 | resize2fs should change the backup superblocks by default. Most | |
1409 | callers of ext2fs_open() should not be touching any superblock fields | |
1410 | which require the backups to be touched. | |
1411 | ||
1412 | Add new function to libext2fs, ext2fs_default_journal_size(), which | |
1413 | returns the default journal size. | |
1414 | ||
26bcc2ca | 1415 | |
6c09475b TT |
1416 | E2fsprogs 1.39 (May 29, 2006) |
1417 | ============================= | |
34a2611c | 1418 | |
34a2611c TT |
1419 | Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems |
1420 | between 2**31 and 2**32 blocks. | |
1421 | ||
34a2611c TT |
1422 | Change mke2fs to use /etc/mke2fs.conf as a configuration file to |
1423 | configure the filesystem features, blocksize, and inode_ratio for | |
1424 | different filesystem types. | |
1425 | ||
6c09475b TT |
1426 | Mke2fs will now create filesystems hash trees and on-line resizing |
1427 | enabled by default, based on the new /etc/mke2fs.conf file. | |
1428 | ||
34a2611c TT |
1429 | The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the |
1430 | filesystem device node in exclusive mode to prevent accidents by | |
1431 | system administrators. In the case of resize2fs and mke2fs, it will | |
1432 | only use exclusive mode if the filesystem is not mounted. | |
1433 | ||
1434 | Fixed a bug in mke2fs which caused it to to fail when creating the | |
1435 | resize inode for large filesystems. (Addresses Debian Bug #346580) | |
1436 | ||
bae55640 TT |
1437 | When allocating space for the RAID filesystems with the stride |
1438 | parameter, mke2fs will now place each portion of the group's inode | |
1439 | table right up after the superblock (if present) in order to minimize | |
1440 | fragmentation of the freespace. | |
1441 | ||
1442 | Speed up mke2fs and e2fsck by writing inode and block bitmaps more | |
1443 | efficiently by writing the inode and block bitmaps in one pass, thus | |
1444 | reducing the number of disk seeks required. | |
1445 | ||
34a2611c TT |
1446 | Add support for on-line resizing to resize2fs. |
1447 | ||
1448 | Fix blkid library so that logic to determine whether or not a device's | |
1449 | cached information in /etc/blkid.tab needs to be verified or not | |
1450 | doesn't get confused by a system clock which is insane (for example, | |
1451 | if the battery is dead on a Macintosh running PPC Linux. (Addresses | |
1452 | Red Hat Bug: #182188) | |
1453 | ||
1454 | The blkid library will now store the UUID of the external journal used | |
1455 | by ext3 filesystems, so that in the future, the userspace mount binary | |
1456 | can use this to find the location of the external journal and pass | |
1457 | this information to the kernel. | |
f3227850 TT |
1458 | |
1459 | E2fsck will now consult a configuration file, /etc/e2fsck.conf to | |
34a2611c TT |
1460 | control how various options should be handled. See the e2fsck.conf |
1461 | man page for more details. (Addresses Debian Bug: #150295) | |
f3227850 | 1462 | |
34a2611c TT |
1463 | E2fsck now prints an explanatory message when delaying a filesystem |
1464 | check when the system is running on battery. (Addresses Debian Bug: | |
1465 | #350306) | |
f2b74cda | 1466 | |
4c02c41c TT |
1467 | E2fsck will detect if the superblock's last mount field or last write |
1468 | field is in the future, and offer to fix if so. (Addresses Debian Bug | |
f3227850 TT |
1469 | #327580) These problems will be fixed automatically in preen mode |
1470 | since Debian's boot sequence bogusly doesn't set the time correctly | |
1471 | until potentially very late in the bootup process, and this can cause | |
1472 | false positives which will cause users' systems to fail to boot. | |
1473 | (Addresses Debian Bugs #343662 and #343645) | |
f2b74cda | 1474 | |
34a2611c TT |
1475 | E2fsck now checks to see if the superblock hint for the location of |
1476 | the external journal is incorrect, and if so, offer to update it. | |
1477 | (Addresses Debian Bug: #355644) | |
1478 | ||
f2b74cda TT |
1479 | Fix e2fsck from segfaulting on disconnected inodes that contain one or |
1480 | more extended attributes. (Addresses Debian Bug: #316736, #318463) | |
1481 | ||
4c02c41c TT |
1482 | E2fsck will stop and print a warning if the user tries running a |
1483 | read/write badblocks test on a read-only mounted root filesystem. | |
1484 | ||
bae55640 TT |
1485 | Fix a memory leak in e2fsck's error paths. (Thanks to Michael |
1486 | C. Thompson for pointing these out; they were originally found using | |
1487 | Coverity.) | |
1488 | ||
f3227850 TT |
1489 | When resizing a file containing a filesystem, resize2fs will expand or |
1490 | truncate a file as necessary. (Addresses Debian Bug: #271607) | |
1491 | ||
bae55640 TT |
1492 | Resize2fs will now automatically determine the RAID stride parameter that |
1493 | had been used to create the filesystem, and use that for newly created | |
1494 | block groups. The RAID stride parameter may also be manually specified | |
1495 | on the command line using the new -S option to resize2fs. | |
1496 | ||
4c02c41c TT |
1497 | Fix mke2fs so that it correctly creates external journals on |
1498 | big-endian machines (such as a S/390). | |
1499 | ||
bae55640 TT |
1500 | Fix a bug in the e2p library which could cause dumpe2fs to (rarely) |
1501 | fail to print out the journal or hash seed UUID. (Thanks to Guillaume | |
1502 | Chambraud for pointing this out.) | |
1503 | ||
1504 | Dumpe2fs will now print the size of the journal (if present). | |
1505 | ||
4c02c41c TT |
1506 | Fix debugfs's set_inode_field command so it can properly set the frag, |
1507 | fsize, uid_high, gid_high, and author fields in the inode instead of | |
1508 | silently failing, and so that setting the i_size actually sets i_size | |
1509 | correctly. | |
1510 | ||
1511 | Add a new debugfs command, set_current_time, which sets fs->now so | |
1512 | that regression test suites can repeatedly modify the filesystem's | |
1513 | last_write fields. | |
1514 | ||
34a2611c TT |
1515 | Fix a bug in debugfs's icheck which would incorrectly report the owner |
1516 | of an extended attribute block. | |
1517 | ||
bae55640 TT |
1518 | Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a |
1519 | print a usage message when an illegal option character is given. | |
1520 | ||
6c09475b TT |
1521 | Fix debugfs's dump_unsued command on filesystems with a 64k blocksize |
1522 | so it won't core dump. (Addresses SourceForge bug #1424311) | |
1523 | ||
bae55640 TT |
1524 | Fix mklost+found so that it creates a full-sized directory on |
1525 | filesystems with larger block sizes. | |
1526 | ||
1527 | Fix a file descriptor leak in blkid library. | |
1528 | ||
4c02c41c TT |
1529 | Fix a display bug in "badblocks -sv" so that the done message properly |
1530 | clears the block number at the end of the test. (Addresses Debian Bug | |
1531 | #322231) | |
1532 | ||
f2b74cda TT |
1533 | Allow fractional percentages to the -m option in mke2fs and tune2fs |
1534 | (Addresses Debian Bug: #80205) | |
1535 | ||
1536 | Use fstat/fstat64 in getsize.c if the the target is a regular file, | |
1537 | instead of attempting to do a binary search. Fix some fd leaks in | |
1538 | error cases. | |
1539 | ||
34a2611c TT |
1540 | Add support for device mapper library to the blkid library to ensure |
1541 | that the "best" (i.e., leaf) device is probed by the blkid library. | |
1542 | ||
4c02c41c TT |
1543 | Fix the blkid library so that it notices when an ext2 filesystem is |
1544 | upgraded to ext3. | |
1545 | ||
1546 | Improve the blkid's library VFAT/FAT detection; it now understands | |
1547 | labels stored in the root directory, and is more paranoid about | |
1548 | checking the FAT superblock values. | |
1549 | ||
34a2611c TT |
1550 | Fixed a fd leak in the uuid library which was causing problems for the |
1551 | LVM tools. (Addresses Debian Bug: #345832) | |
1552 | ||
4c02c41c TT |
1553 | Add support for the reiser4 and software suspend partitions to the |
1554 | blkid library. Also add support for extract the label from iso9660 | |
1555 | filesystems. | |
1556 | ||
f2b74cda TT |
1557 | Fix a compile_et bug which miscount the number of error messages if |
1558 | continuations are used in the .et file. | |
1559 | ||
1560 | Add extra sanity checks to protect users from unusual cirucmstances | |
1561 | where /etc/mtab may not be sane, by checking to see if the device is | |
1562 | reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug | |
1563 | #319002) | |
1564 | ||
34a2611c TT |
1565 | Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian |

4c02c41c | 1567 | |
f2b74cda TT |
1568 | Fix use-after-free bug in e2fsck when finishing up the use of the |
1569 | e2fsck context structure. | |
1570 | ||
34a2611c TT |
1571 | Fixed spelling mistakes, typos, and otherwise clarified man pages and |

1585 | Update config.guess and config.sub to latest version (2006-02-23) from |
1586 | FSF. | |

1588 | Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian | |
1589 | Bugs: #360661, #360317) | |
1590 | ||
34a2611c TT |
1591 | Fixed the Makefile so that they work correctly on newer versions of |
1592 | GNU make (i.e., 3.81). | |
1593 | ||
f2b74cda TT |
1594 | Add valgrind support to the regression test suites, and eliminate |
1595 | false positives from valgrind. | |
1596 | ||
4c02c41c TT |
1597 | Add a regression test suite for the blkid library. |
1598 | ||
f2b74cda TT |
1599 | Fix a fencepost error in resize2fs caught by valgrind. |
1600 | ||
4c02c41c TT |
1601 | Fix compiler warnings about missing memcpy prototypes. |
1602 | ||
1603 | We no longer have the sparc assembly code in the header file any more, | |
1604 | so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would | |
1605 | break compiles on the sparc architectures when using gcc. | |
1606 | ||
1607 | In the libext2fs library, add the new field fs->now which if non-zero | |
1608 | is used instead of the system time when setting various filesystem | |
1609 | fields (last modified time, last write time, etc.) | |
1610 | ||
1611 | Fix gcc 4.01 complaints by adding a missing #include <string.h> to | |
1612 | ext2fs.h which is needed since the inline functions use memcpy(). | |
1613 | (Addresses Sourceforge Bug #1251062) | |

1617 | needed during the build process. This avoids potential problems when | |
1618 | cross-compiling and some of the options specified in CFLAGS or LDFLAGS | |
1619 | are not recognized as valid by the host compiler. (Addresses | |
1620 | Sourceforge Bug #1261547) | |
1621 | ||
1622 | Clean up the blkid library by making the superblock and generic i/o | |
1623 | functions to be more generic. Clean up interface to the probe | |
1624 | function, and fix memory leak. Finallly, remove an unneeded reference | |
1625 | to probe.h in the lib/blkid/resolve.c | |
1626 | ||
3285a9c9 TT |
1627 | Add an ext2fs_read_bb_FILE regression test to confirm proper detection |
1628 | of invalid block #'s. | |
1629 | ||
34a2611c TT |
1630 | The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to |
1631 | indicate that the the function read/writes the memory location. | |
1632 | ||
3285a9c9 TT |
1633 | Fix various gcc -Wall complaints. |
1634 | ||
1635 | Add a dependency to make sure that the subdirectories are created | |
1636 | before creating all of the object files, in order to address parallel | |
1637 | build problem in the library Makefiles. (Addresses Sourceforge Bug: | |
1638 | #1261553) | |
1639 | ||
1640 | Add $(LDFLAGS) to the command line argument when generating an ELF or | |
1641 | Solaris shared library, to allow cross-compile and other builds that | |
1642 | might need to specify -L paths to needed libraries. (Addresses | |
1643 | Sourceforge Bug #1261549) | |
1644 | ||
bae55640 TT |
1645 | Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially |
1646 | intended for testing purposes. It allows an ext2/ext3 developer to | |
1647 | create very large filesystems using sparse files where most of the | |
1648 | block groups are not initialized and so do not require much disk | |
1649 | space. Eventually it could be used as a way of speeding up mke2fs and | |
1650 | e2fsck for large filesystem, but that would be best done by adding an | |
1651 | RO_COMPAT extension to the filesystem to allow the inode table to be | |
1652 | lazily initialized on a per-block basis, instead of being entirely | |
1653 | initialized or entirely unused on a per-blockgroup basis. | |
1654 | ||
6c09475b TT |
1655 | Fix backwards compatibility so e2fsprogs will better compile on Linux |
1656 | 2.0.35 systems. | |

fea95ffc | 1665 | E2fsprogs 1.38 (June 30, 2005) |
1f965c8d TT |
1666 | ============================== |
1667 | ||
1668 | Fix blkid's test programs (built with "make check") compile correctly | |
1669 | even without "configure --enable-blkid-debug". | |
1670 | ||
1671 | Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict | |
1672 | type aliasing rules on newer gcc compilers. (Addresses Red Hat | |
1673 | Bugzilla ##161183.) | |
1674 | ||
1675 | Fix com_err library to make it more compatible with recent changes | |
1676 | made to the com_err library in MIT Kerberos V5 version 1.4. | |
1677 | (Addresses Sourcefroge Bug #1150146) | |
1678 | ||
1679 | General cleanup of messages printed by e2fsprogs programs for grammar, | |
1680 | consistency, and to make life easier for translators. Fixed a few | |
1681 | strings containing English that had not been marked as needing | |
1682 | translations. Removed strings that do not need to be translated, to | |
1683 | make life easier for translators. | |
1684 | ||
1685 | Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to | |
1686 | test to see if a device appears to be in use instead of just relying | |
1687 | on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594). | |
1688 | ||
1689 | Fix portability problem in the filefrag program affecting platforms | |
1690 | where the size of an integer is smaller than the size of a long. | |
1691 | (Addresses Debian Bug #309655) | |
1692 | ||
1693 | Mke2fs will now use a larger journal by default for filesystems | |
1694 | greater than 4GB. (128 MB instead of 32MB). | |
1695 | ||
1696 | Mke2fs will refuse to create filesystems greater than 2**31-1 blocks, | |
1697 | unless forced. This is to avoid signed vs. unsigned kernel bugs in | |
1698 | block numbers that still need to be fixed. | |
1699 | ||
1700 | The blkid program has a new option which will more efficiently search | |
1701 | for device when it is known (or expected) that only one matching | |
1702 | device will be found in the system, such as when doing a lookup by | |
1703 | UUID. | |
1704 | ||
1705 | Debian's e2fsprogs-specific initrd fragment will avoid including | |
1706 | unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD | |
1707 | and LD_LIBRARY_PATH, and filtering out libraries found in | |
1708 | /etc/ld.so.preload. (Addresses Debian Bug: #304003) | |
1709 | ||
1710 | Fixed a potential portability issue in the blkid programs for | |
1711 | architectures where the char type is unsigned. (Addresses Sourceforge | |
1712 | Bug: #1180585) | |
1713 | ||
1714 | Fix a bug in filefrag so that it doesn't falsely count an extra | |
1715 | discontinuity when the first block found is an indirect block. | |
1716 | (Addresses Debian Bug #307607). | |
1717 | ||
1718 | Fix blkid's recognition of cramfs filesystems, and enhance it to be | |
1719 | able to handle cramfs labels. | |
1720 | ||
1721 | Fix debugfs's stat command to not core dump when a filesystem is not | |
1722 | open. | |
1723 | ||
1724 | Fix e2fsck's handling of error conditions caused by the resize inode | |
1725 | claiming blocks that are also used by other inodes, a filesystem | |
1726 | corruption which was commonly caused by a bug in Fedora Core 3's | |
1727 | resize2fs program. | |
1728 | ||
1729 | Fixed bug in filefrag which caused it to fail on non-ext2/3 | |
1730 | filesystems. (Addresses Debian Bug: #303509) | |
1731 | ||
1732 | If the superblock last mount time indicates that the system clock may | |
1733 | not be accurate, then e2fsck will omit checking inodes' deletion time | |
1734 | field for indications of a potential corrupted orphaned inode list. | |
1735 | (Previously e2fsck only ommited these LOW_DTIME checks when the | |
1736 | superblock's last write time looked insane.) | |
1737 | ||
1738 | Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs. | |
1739 | (Addresses Debian bug #302200) | |
1740 | ||
1741 | Make the blkid library more paranoid about being run from setgid | |
1742 | programs, and to use __secure_getenv() from libc if it is available. | |
1743 | ||
1744 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
1745 | (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593 | |
1746 | and Sourceforge Bug: #1189803) | |
1747 | ||
1748 | Updated and fixed translations. | |
1749 | ||
1750 | Fixed various Debian packaging issues --- see debian/changelog for | |
1751 | details. | |
1752 | ||
1753 | Programmer's notes: | |
1754 | ------------------- | |
1755 | ||
1756 | Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been | |
1757 | changed to take an unsigned int for the bit number. Negative bit | |
1758 | numbers were never allowed (and didn't make any sense), so this should | |
1759 | be a safe change. This is needed to allow safe use of block numbers | |
1760 | greater than or equal to 2**31. | |
1761 | ||
1762 | The compile_et program will avoid recreating generated foo_err.c and | |
1763 | foo_err.h files if no changes are necessary. The compile_et program | |
1764 | will also atomically replace these files to avoid a potential parallel | |
1765 | build race problem on SMP systems. (Addresses Sourceforge Bug: | |
1766 | #1157933) | |
1767 | ||
1768 | Added a new function to the blkid library, blkid_probe_all_new(), | |
1769 | which only probes newly added disk devices, and change | |
1770 | blkid_find_dev_with_tag() to use this function so that when a | |
1771 | requested tag is not found, devices that were previously not checked | |
1772 | are searched before searching all devices in the system. | |
1773 | ||
1774 | Added new functions to the blkid library, blkid_dev_set_search() and | |
1775 | blkid_dev_has_tag(). | |
1776 | ||
1777 | E2fsck's problem strings can now use @m and @n as abbrevations for | |
1778 | "multiply-claimed" and "invalid", respectively. | |
1779 | ||
1780 | The e2fsprog.pot file now has an explanation of how the @-expansion | |
1781 | and %-expansion works, and strings in e2fsck/problem.c which contain @ | |
1782 | characters now have comments in e2fsprogs.pot with the @-expansion to | |
1783 | make life easier for translators. | |
1784 | ||
1785 | Fixed missing return values in the ext2fs library which could cause it | |
1786 | to return random garbage in certain error conditions. | |
1787 | ||
1788 | Allow the current time to be overriden via the E2FSCK_TIME environment | |
1789 | variable for use in regression tests. | |
1790 | ||
1791 | The test scrpit driver program now exits with a non-zero status if | |
1792 | there any of its test that it ran failed. | |
1793 | ||
1794 | Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge | |
1795 | Bug: #1157933) | |
1796 | ||
1797 | Fixed "make check" so that it compiles correctly even when e2fsprogs' | |
1798 | header files have not be installed in the system include directories. | |
1799 | (Addresses Sourceforge Bug: #1180572) | |
1800 | ||
1801 | Fixed gcc -Wall nits. | |
1802 | ||
1803 | ||
fd4b28ef TT |
1804 | E2fsprogs 1.37 (March 21, 2005) |
1805 | =============================== | |
1806 | ||
1807 | Add support for checking the validity of Extended Attributes stored in | |
1808 | inodes to e2fsck. | |
1809 | ||
1810 | Add support for dumping the contents of large inodes to debugfs, | |
1811 | including the extended attributes stored in inodes. | |
1812 | ||
1813 | Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that | |
1814 | when we create a new inode we make sure that the extra information in | |
1815 | the inode (any extra fields in a large inode and any ea-in-inode | |
1816 | information) is initialized correctly. This can take place when | |
1817 | mke2fs creates the root and lost+found directory, when e2fsck creates | |
1818 | a new root inode or a new lost+found directory, and when the user uses | |
1819 | the debugfs write, mknod, or mkdir commands. Otherwise, the newly | |
1820 | create inode could inherit garbage (or old EA information) from a | |
1821 | previously deleted inode. | |
1822 | ||
1823 | Fixed a bug in e2fsck so it would notice if a file with an extended | |
1824 | attribute block was exactly 2**32 blocks, such that i_blocks wrapped | |
1825 | to zero. | |
1826 | ||
1827 | Added support to filefrag to detect files which are using the new | |
1828 | experimental file extents format, and use the non-ext2 algorithm in | |
1829 | that case. Fixed a bug to avoid reporting a false discontinuity if | |
1830 | there is one or more unallocated blocks at the beginning of a file. | |
1831 | ||
1832 | Duplicated a check for noticing whether or not the number of blocks | |
1833 | (given a certain blocksize) is greater than 2**32 when the | |
1834 | BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This | |
1835 | allows mke2fs to automatically use a larger blocksize when creating a | |
1836 | filesystem on a very large device when run on systems that do not | |
1837 | support BLKGETSIZE64. | |
1838 | ||
1839 | Fix the I18N build which was broken in e2fsprogs 1.36 because the | |
1840 | build system had been switched to treat the .gmo files as shipped | |
1841 | files (for backwards compatibility with systems that have older GNU | |
1842 | I18N tools installed), but the gen_tarball.in script was still | |
1843 | removing the .gmo files from the official source distribution. | |
1844 | ||
1845 | Fixed various Debian packaging issues --- see debian/changelog for | |
1846 | details. (Addresses Debian Bugs ##296769, #299341) | |
1847 | ||
1848 | Programmer's notes: | |
1849 | ------------------- | |
1850 | ||
1851 | Added new functions to the e2p library which convert between a string | |
1852 | and os_type: e2p_os2string() and e2p_string2os(), and used them to | |
1853 | make the generated binaries more compact. | |
1854 | ||
1855 | Fixed a compile-time error on Darwin systems. | |
1856 | ||
1857 | Cleaned up the lib/ext2fs Makefile slightly. | |
1858 | ||
1859 | ||

1860 | E2fsprogs 1.36 (February 4, 2005) |
1861 | ================================= | |
2b0dc0ac TT |
1862 | |
1863 | All of the patches that were applied to Fedore Core 3's | |
1864 | e2fsprogs-1.35-11.2 have been integrated, although sometimes with a | |
1865 | lot of bug fixes first. Users of Fedora Core 3 are strongly | |
1866 | encouraged to upgrade to e2fsprogs 1.36 as soon as possible. | |
1867 | ||
1868 | Add support for filesystem with the online resizing via resize inode | |
1869 | feature. Fixed numerous bugs from the Fedora patches. The Fedora | |
1870 | patches also didn't bother to do any consistency checking on the | |
1871 | resize inode, or add any tests to the regression test suite. The "-R | |
1872 | resize=4g" option to mke2fs was a no-op in the Fedora patches, despite | |
1873 | being listed in mke2fs's usage message. All of these shortcomings | |
1874 | have been corrected. | |
1875 | ||
1876 | E2fsck can also also fix filesystems trashed by Fedora's resize2fs | |
1877 | program. In order to do this, the user must run the commands: | |
1878 | ||
d0a3b46c | 1879 | debugfs -w /dev/hdXXX -R "features ^resize_inode" |
2b0dc0ac TT |
1880 | e2fsck -f /dev/hdXXX |
1881 | ||
1882 | Optionally, the ext2prepare command can be used to re-enable online | |
1883 | resizing after the filesystem has been fixed. | |
1884 | ||
1885 | The fsck program will now accept an optional filedescriptor argument | |
1886 | to the -C option. (The Fedora version of this patch would sometimes | |
1887 | cause fsck to ignore a parameter on fsck's command line in some rare | |
1888 | cases, sigh.) | |
1889 | ||
dc256973 TT |
1890 | Make sure e2fsprogs doesn't write garbage into the reserved portion of |
1891 | large inodes. | |
1892 | ||
1893 | Make sure resize2fs releases the blocks belonging to the old inode | |
1894 | table blocks when moving the inode table. (Addresses Debian Bug: | |
1895 | #290894) | |
1896 | ||
1897 | Skip the r_resize_inode test if resize2fs is not compiled (due to | |
1898 | configure --disable-resizer) | |
1899 | ||
1900 | E2fsck now checks the summary filesystem accounting information, and | |
1901 | if any of the information is obviously wrong, it will force a full | |
1902 | filesystem check. (Addresses Debian Bug #291571) | |
1903 | ||
1904 | Fix e2fsck to not complain when the resize_inode feature is enabled, | |
1905 | s_reserved_gdt_blocks is zero, and there is no DIND block allocated in | |
1906 | the resize inode. | |
1907 | ||
8ceb55f0 TT |
1908 | Fix e2fsck to note delete symlinks that contain an extended attribute |
1909 | after the ext_attr feature flag has been cleared. (Addresses Red Hat | |
1910 | Bugzilla #146284). | |
1911 | ||
dc256973 TT |
1912 | Add new utility program, copy_sparse.c, which is very useful |
1913 | for dealing with large sparse files (such as e2image files). | |
1914 | ||
1915 | Add support for jnl_blocks[] for debugfs's set_super_value. | |
1916 | ||
1917 | Fix filefrag so that it works correctly with sparse files. | |
1918 | ||
3eee5e9e TT |
1919 | Filefrag -v will print first and last blocks. |
1920 | ||
dc256973 TT |
1921 | Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs |
1922 | and dumpe2fs. | |
1923 | ||
8ceb55f0 TT |
1924 | Add mke2fs support so that it can support filesystems larger than 4TB |
1925 | automatically, by retrying with a 4k blocksize if the device size is | |
1926 | too big to be expressed using a 1k blocksize. (Addresses Sourceforge | |
1927 | bug #1106631) | |
1928 | ||
dc256973 TT |
1929 | Change blkid to test for NTFS first because Windows sometimes doesn't |
1930 | clear enough of the parition to confuse the probing routines into | |
1931 | thinking the old filesystem type is still valid. (Addresses Debian | |
1932 | Bug #291990) | |
1933 | ||
66fa0de8 TT |
1934 | Add support for swap partition label and uuid's in the blkid library. |
1935 | ||
dc256973 TT |
1936 | Add support to the blkid library to recognize Oracle ASM volumes. |
1937 | ||
1938 | Make blkid -t display all devices that match the specified criteria, | |
8ceb55f0 TT |
1939 | not just the first one, and work more consistently when the blkid |
1940 | cache file is not available or set to /dev/null. (Addresses Debian | |
1941 | Bug #290530 and #292425) | |
dc256973 | 1942 | |
2b0dc0ac TT |
1943 | Badblocks will now correctly display block numbers greater than |
1944 | 999,999,999 in its progress display. | |
1945 | ||
1946 | The tune2fs program will not allow the user from setting a ridiculous | |
1947 | number of reserved blocks which would cause e2fsck to assume the | |
1948 | superblock was corrupt. E2fsck's standards for what is a ridiculous | |
1949 | number of reserved block has also been relaxed to 50% of the blocks in | |
1950 | the filesystem. | |
1951 | ||
1952 | The blkid library will return vfat in preference to msdos, and ext3 in | |
1953 | preference to ext2 (if the journalling flag is set) so that mount will | |
1954 | do the right thing. (Addresses Debian bug #287455) | |
1955 | ||
1956 | Mke2fs will now use the -E option for extended options; the old -R | |
1957 | (raid options) option is still accepted for backwards compatibility. | |
1958 | Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707) | |
1959 | ||
1960 | Mke2fs will now accept a size in megabytes, gigabytes, and other units | |
1961 | (via "32m" or "4g" on the command line) if the user finds this more | |
1962 | convenient than specifying a block count. | |
1963 | ||
1964 | Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode | |
1965 | cache conherency problem. | |
1966 | ||
1967 | Debugfs now supports a new command, set_inode_field, which allows a | |
1968 | user to manually set a specific inode field more conveniently, as well | |
1969 | as set entries in the indirect block map. | |
1970 | ||
1971 | Debugfs's set_super_value command has been enhanced so that the user | |
1972 | can set most superblock fields, including the date/time fields and | |
1973 | some of the more newsly added superblock fields. | |
1974 | ||
1975 | E2fsprogs programs now accept an offset to be passed to the file | |
1976 | specifiers, via the syntax: "/tmp/test.img?offset=1024". | |
1977 | ||
1978 | E2fsprogs programs will now accept blocksizes up to 65536; kernel | |
1979 | support on the x86 doesn't exist for now, but it can be useful on | |
8ceb55f0 TT |
1980 | other architectures with page sizes greater than 4k. There are 2.6 |
1981 | kernel patches out there which enable this, but they are of this | |
1982 | writing still experimental. | |
2b0dc0ac | 1983 | |
4ee558fc TT |
1984 | The e2image command now takes the -s option which will scramble |
1985 | directory entries for raw image files. | |
1986 | ||
1987 | Fix a file descriptor leak in the filefrag program. | |
1988 | ||
1989 | Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not | |
1990 | present. | |
1991 | ||
2b0dc0ac TT |
1992 | Fix bug in debugfs where kill_file would lead to errors when deleting |
1993 | devices and symlinks. (Sourceforge Bugs #954741 and #957244) | |
1994 | ||
1995 | Fix bug in the blkid library when detecting the ocfs1 filesystem | |
1996 | ||
1997 | Remove obsolete EVMS 1.x and a.out DLL support. | |
1998 | ||
1999 | E2fsck will attempt to recover from a journal containing illegal blocks. | |
48301129 TT |
2000 | |
2001 | Fixed two potential ordering constraint problems in e2fsck which might | |
2002 | cause the filesystem to be corrupted if e2fsck is interrupted during a | |
2003 | (extremely narrow) race window. Thanks to Junfeng Yang from the | |
2004 | Stanford Metacompilation group for pointing this out. | |
2005 | ||
2006 | Fixed bug in e2fsck where it would not accurately detect whether or | |
2007 | not the system is running on adaptor if the ACPI device representing | |
2008 | the AC adapter didn't correspond to the what was used on IBM | |
2009 | Thinkpads. | |
2010 | ||
2011 | Change e2fsck to accept directories greater than 32MB. | |
2012 | ||
2013 | Fix e2fsck so that a checkinterval of zero disables a time-based check | |
2014 | of the filesystem. | |
2015 | ||
2016 | Debugfs will check the DEBUGFS_PAGER enviroment variable in preference | |
2017 | to the PAGER environment variable. (Addresses Debian Bug #239547) | |
2018 | ||
2019 | Tune2fs will not mark rewrite the superblock if the feature bitmasks | |
2020 | are not modified. | |
2021 | ||
2022 | The debugfs program will set the filetype information when creating a | |
2023 | link. | |
2024 | ||
2025 | Add debugfs -d option to use a separate source of data blocks when | |
2026 | reading from an e2image file. | |
2027 | ||
2028 | Add e2image -I option which allows the e2image metadata to be | |
2029 | installed into a filesystem. | |
2030 | ||
2031 | Fixed bug in the badblocks program which caused "done" to always | |
2032 | appear in english even when a translation was available. (Addresses | |
2033 | Debian Bug #252836) | |
2034 | ||
2035 | The blkid program has a new option -o which controls the output format | |
2036 | of the blkid program; this is makes blkid more convenient to use in | |
2037 | shell scripts. | |
2038 | ||
2039 | Fix a minor bug in uuid library, which was not using the full 14 bits | |
2040 | of clock sequence when generating UUID's. | |
2041 | ||
2042 | Fix a Y8.8888K problem in the uuid library. | |
2043 | ||
2044 | Logsave now creates a new session id for itself to avoid getting | |
2045 | killed by init whan transitioning between init levels. | |
2046 | ||
2047 | Change the licensing of the UUID library to be the 3-clause BSD-style | |
2048 | license; this allows Apple to use the uuid library in Darwin. | |
2049 | ||
2050 | Add ocfs and ocfs2 probe support into the blkid library. | |
2051 | ||
2052 | Fix a memory and file descriptor leak in the blkid library. | |
2053 | ||
2054 | The blkid library will revalidate the device if the system time is | |
2055 | earlier than last verification time of the device, since that | |
2056 | indicates that the system time is probably nottrustworthy. | |
2057 | ||
2058 | The blkid library will override the default location of the blkid.tab | |
2059 | file by the BLKID_FILE environment variable, if it is available. | |
2060 | ||
2061 | Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6. | |
2062 | ||
2063 | Add various portability fixes for lame new versions of glibc, Darwin | |
2064 | and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian | |

2067 | Add support for Windows 9x/NT under Cygwin. | |
48301129 TT |
2068 | |
2069 | Updated and clarified various man pages. (Addresses Debian Bugs #236383, | |
2b0dc0ac | 2070 | #241940, #238741, #242995, #256669, #268148, #256760, #273679) |
48301129 TT |
2071 | |
2072 | Updated and fixed translations. (Addresses Debian bugs #244105, #262836) | |
2073 | ||
2074 | Update the rpm spec files so that it works better with Fedora core 2 | |
2075 | and RH9. | |
2076 | ||
2077 | Fixed various Debian packaging issues (see debian/changelog). In | |
2078 | particular, fixed the Debian initrd scripts. (#241183, #248050, | |
2079 | #253595, #247775) | |

2081 | ||
2082 | Programmer's notes: | |
2083 | ------------------- | |
2084 | ||
2b0dc0ac | 2085 | Fixed various gcc -Wall warnings. |
48301129 TT |
2086 | |
2087 | The uuid library now has new functions uuid_unparse_upper() and | |
2088 | uuid_unparse_lower() which forces the case of the hex digits to be | |
2089 | upper case, or lower case. | |
2090 | ||
2091 | The build process has been speeded up by enhancing the subst program | |
2092 | to update the modtime on the generated files even when the generated | |
2093 | file hasn't changed. | |
2094 | ||
2095 | The uuid library now uses C99 stdint.h types instead of custom types. | |
2096 | ||
2097 | Updated config.guess and config.sub with newer versions from the FSF. | |
2098 | ||
2099 | Removed out of date .cvsignore files from the source distribution. | |
2100 | ||
2b0dc0ac TT |
2101 | The ext2fs_unlink() function will return an error if both the name and |
2102 | inode number are unspecified, to avoid doing something surprising | |
2103 | (such as unconditionally deleting the first directory entry). | |
2104 | Directory entries are now deleted by coalescing them with the previous | |
2105 | directory entry if possible, to avoid directory fragmentation. This | |
2106 | is not an issue with the e2fsprogs suite, but may be a problem for | |
2107 | some of the users of libext2fs, such as e2tools. | |
2108 | ||
2109 | Add support for version numbers of the form "1.36-rc1". | |
2110 | ||
48301129 TT |
2111 | Fix build of mke2fs.static. |
2112 | ||
dc256973 TT |
2113 | Add basic ext2fs library support for large (EA in inode) inodes. |
2114 | ||
48301129 TT |
2115 | The test_io mechanism can now abort after n reads or writes to a |
2116 | particular block. The block is specified by TEST_IO_BLOCK environment | |
2117 | variable, and the read/write count by the TEST_IO_READ_ABORT and | |
2118 | TEST_IO_WRITE_ABORT environment variables. The block data is now only | |
2119 | dumped if the 0x10 bit is set in TEST_IO_FLAGS. | |
2120 | ||
2121 | UUID_DEFINE() in the uuid library now creates a static variable, with | |
2122 | __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can | |
2123 | be used in header files. | |
2124 | ||
2b0dc0ac TT |
2125 | Add support for the install-strip and install-shlibs-strip targets, as |
2126 | suggested by the GNU coding guielines. "make install" no longer | |
2127 | strips the binaries which are installed. | |
2128 | ||
3eee5e9e TT |
2129 | Remove support for the --enable-old-bitops configure option which was |
2130 | only for very old sparc systems. | |
2131 | ||
2132 | Remove support for --enable-clear-htree; this was only needed during | |
2133 | the early development of the htree patch. | |
2134 | ||
2b0dc0ac TT |
2135 | Use Linux-kernel-style makefile output so it is easier to see compiler |
2136 | warnings. | |
2137 | ||
2138 | Update gettext files to version 0.14.1. | |
2139 | ||
2140 | Update to use autoconf 2.5x. | |
2141 | ||
2142 | Improved support for compiling e2fsprogs under dietlibc. | |
2143 | ||
4ee558fc TT |
2144 | Make e2fsprogs portable to Solaris and FreeBSD systems. |
2145 | ||
8ceb55f0 TT |
2146 | Add blkid_verify(), blkid_get_library_version(), and |
2147 | blkid_parse_version_string() functions to the blkid library. | |
dc256973 TT |
2148 | |
2149 | Add pkg-config files for e2fsprogs's libraries. | |
2150 | ||
2151 | Fix "make uninstall" to so that it removes everything that is installed. | |
2152 | ||
3eee5e9e TT |
2153 | Add a configure --enable-maintainer-mode option which enables the |
2154 | makefile rules to rebuild the configure script from configure.in, and | |
2155 | to reubuild the .gmo files in po directory. | |
2156 | ||
2157 | Drop the sparc assembly bitwise operations; it's less efficient | |
2158 | than the GCC 3.4 compile code and triggers compiler warnings on | |
2159 | sparc64. Thanks to Matthias Andree for his analysis and suggestions. | |

2163 | E2fsprogs 1.35 (February 28, 2004) |
2164 | ================================== | |
2165 | ||
48301129 | 2166 | E2fsck has a new -k option, which in conjunction with the -c options, |
b70b1167 TT |
2167 | preserves the existing badblocks list. |
2168 | ||
48301129 | 2169 | Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d. |
b70b1167 TT |
2170 | |
2171 | E2fsprogs will now deal correctly with symlinks that contain | |
2172 | extended attribute information, which can be created using SE Linux. | |
2173 | (Addresses Debian Bug #232328) | |
2174 | ||
2175 | Remove a double longjump into an invalid stack frame bug in e2fsck. | |
2176 | (This was during an abort sequence, which normally worked on Linux and | |
2177 | caused a core dump on other operating systems.) | |
c4c30b20 | 2178 | |
1daf7585 TT |
2179 | Fix NLS bug in e2fsck, by avoiding trying to expand an empty string |
2180 | (the NLS library will replace "" with the .po header information). | |
2181 | ||
c4c30b20 TT |
2182 | Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core |
2183 | dump due to a division by zero error. (Addresses Debian bug #207082) | |
2184 | ||
151a7162 TT |
2185 | Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem |
2186 | when reconnecting a directory requires creating a lost+found | |
2187 | directory. (Addresses Debian bug #219640). | |
2188 | ||
2189 | Fixed a bug where e2fsck would bomb out if a journal needed to be | |
2190 | replayed when using an alternate superblock. | |
2191 | ||
48301129 | 2192 | E2fsck will give an extra grace period before actually forcing a check |
c4c30b20 TT |
2193 | if the laptop is running on battery. The next time fsck runs while |
2194 | the system is on the AC mains, or after the grace period is exceeded, | |
2195 | the filesystem will be checked. (Addresses Debian bug #205177) | |
2196 | ||
2197 | E2fsck will inform the user when there are 5 or fewer mounts before a | |
2198 | filesystem check will be forced. (Addresses Debian bug #157194) | |
2199 | ||
2200 | Fix e2fsck's handling of corrupted indirect blocks in the bad block. | |
2201 | We now correctly handle the case where there is an overlap between a | |
2202 | block group descriptor or a superblock and a bad block indirect block. | |
2203 | In the case where the indirect block is corrupted, we now suggest | |
2204 | "e2fsck -c". | |
2205 | ||
1daf7585 TT |
2206 | Fix byte swap bugs in e2fsck that caused the journal backup location |
2207 | in the superblock and symlinks created by SE Linux to be cleared | |
2208 | by e2fsck on big-endian machines. (Addresses Debian bug #228723) | |
2209 | ||
c4c30b20 TT |
2210 | E2fsck -c now replaces the current list of bad blocks with the ones |
2211 | found by badblocks. | |
2212 | ||
2213 | Fix bugs in e2fsck and tune2fs which could cause a core dump if a | |
2214 | non-existent LABEL or UUID specifier is to e2fsck or tune2fs. | |
2215 | ||
2216 | Fix a potential bug in e2fsck which could cause it to core dump when | |
2217 | trying to print the location of the backup superblock. | |
2218 | ||
2219 | Protect against a potential core dump in e2fsck when printing a | |
2220 | message about backup superblocks. | |
858dd7b1 | 2221 | |
6826bde5 TT |
2222 | Add support for backing up the journal inode location in the |
2223 | superblock. E2fsck will automatically save the journal information in | |
2224 | the superblock if it is not there already, and will use it if the | |
2225 | journal inode appears to be corrupted. ext2fs_add_journal_inode() | |
2226 | will also save the backup information, so that new filesystems created | |
2227 | by mke2fs and filesystems that have journals added via tune2fs will | |
2228 | also have journal location written to the superblock as well. | |
2229 | Debugfs's logdump command has been enhanced so that it can use the | |
2230 | journal information in the superblock. | |
c4c30b20 TT |
2231 | |
2232 | E2fsck will now update all superblocks when moving the journal inode. | |
6826bde5 TT |
2233 | |
2234 | Shrink the size of the e2fsck executable by moving some initialized | |
2235 | variables to the BSS segment. | |
2236 | ||
2237 | E2fsck will avoid printing the ^A and ^B characters which bracket the | |
2238 | progress bar when stdout and stdin are a tty device instead of a pipe | |
2239 | to another program. (Addresses Debian bug #204137) | |
2240 | ||
151a7162 TT |
2241 | Debugfs's mkdir command will automatically expand the directory if |
2242 | necessary. (Addresses Debian Bug: #217892) | |
2243 | ||
2244 | Fixed a bug in debugfs so that copying a file from /dev/null uses the | |
2245 | correct mode bits. (Addresses Debian Bug: #217456) | |
2246 | ||
2247 | If the environment variables DEBUFS_PAGER and PAGER are not set, | |
2248 | debugfs now searches for the appropriate pager to use, beginning with | |
2b5ddd75 | 2249 | /usr/bin/pager, and then falling back to 'more' and 'less'. |
1daf7585 TT |
2250 | (Addresses Debian bug #221977) |
2251 | ||
b70b1167 TT |
2252 | Debugfs will now support 2.6 device numbers where the major or minor |
2253 | number may be larger than 255. (Addresses Sourceforge bug #865289) | |

858dd7b1 TT |
2260 | Fix regression tests so they work correctly when e2fsprogs is compiled |
2261 | with configure --disable-htree. | |
2262 | ||
1daf7585 TT |
2263 | Fix bug in uuid library when there is no network card and the library |
2264 | is generating a time-based uuid. The random MAC address was not | |
2265 | correctly generated to be a multicast address. | |
2266 | ||
858dd7b1 | 2267 | Add compile_et extensions from Heimdall that were missed the first time |
48301129 | 2268 | around. |
858dd7b1 TT |
2269 | |
2270 | Fix bug in badblocks when using O_DIRECT; we need to make sure that | |
2271 | we're reading from an offset which is page aligned. For read-only and | |
2272 | read-write tests, we try to recover after an error so that we can | |
2273 | continue reading on page-aligned boundaries. (Addresses Debian Bug | |
2274 | #203713) | |
2275 | ||

2286 | Programmer's notes: | |
2287 | ------------------- | |
2288 | ||
b70b1167 TT |
2289 | Fixed a build problem so that e2fsprogs would compile with the |
2290 | --enable-profile option to configure selected. (Addresses Sourceforge | |
2291 | bug #811408) | |
2292 | ||
2293 | Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat | |
2294 | Bugzilla Bug #112448) | |
2295 | ||
c4c30b20 TT |
2296 | Centralize code which calculates the location of the superblock |
2297 | and block group descriptors so that it is in a single library routine. | |
2298 | ||
6826bde5 TT |
2299 | Added two new functions, ext2fs_file_open2() and |
2300 | ext2fs_inode_io_intern2() which take a pointer to an inode structure. | |
2301 | ||
2302 | Fix compile_et to output the correct prototype for | |
2303 | initialize_xxx_err_table_r() in the header file. (Addresses Debian | |
2304 | bug #204332) | |
2305 | ||
2306 | In the lib/et makefile, make sure com_err.info is deleted on "make clean". | |
2307 | ||
858dd7b1 TT |
2308 | Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if |
2309 | present. This is for when we try stuffing an int into void * pointer. | |
2310 | ||
2311 | Fix type-punning which can cause gcc 3.x to miscompile code by getting | |
2312 | confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(), | |
2313 | and ext2fs_resize_mem() all now take a 'void *' instead of a 'void | |
2314 | **'. The EVMS code uses an ugly union approach since we don't want to | |
2315 | modify the EVMS interfaces. | |
2316 | ||
2317 | Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to | |
2318 | aid build process on systems can use invoke GNU make as "gmake". | |
2319 | ||

9c7ec178 TT |
2330 | E2fsprogs 1.34 (July 25, 2003) |
2331 | =============================== | |
2332 | ||
2333 | Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in | |
2334 | a tight loop while waiting for a child fsck to exit in some cases. | |
2335 | This burns CPU times which slows down the low-level filesystem check. | |
2336 | ||
2337 | Added code to mke2fs to assure that the default block size for a | |
2338 | filesystem is at least as big as the sector size of the device, if it | |
2339 | can be determined. | |
2340 | ||
2341 | Changed mke2fs and resize2fs to round the default size of a filesystem | |
2342 | to be an even multiple of the VM pagesize in order to avoid a Linux | |
2343 | kernel bug introduced when the storage of the buffer cache was moved | |
2344 | into the page cache. | |
2345 | ||
2346 | Mke2fs will warn the user when creating a filesystem with journaling | |
2347 | and a blocksize greater than 4096. (Addresses Debian bug #193773) | |
2348 | ||
2349 | Fixed a bug in resize2fs which caused it to fail on filesystems with a | |
2350 | non-empty bad block list. Resize2fs now discards any blocks on the | |
2351 | badblock list which are no longer part of the filesystem as the result | |
2352 | of a filesystem shrink. (Note: this means that shrinking and then | |
2353 | enlarging a filesystem is no longer a reversible operation; | |
2354 | information about bad blocks in the part of the filesystem which is to | |
2355 | be chopped off will be lost.) | |
2356 | ||
2357 | Changed resize2fs so the user can use prefixes to specify the units of | |
2358 | the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), | |
2359 | and to make the error and informational messages explicitly display | |
2360 | the blocksize used by the filesystem, in order to avoid confusion. | |
2361 | (Addresses Debian bug: #189814) | |
2362 | ||
2363 | Added a new debugfs command, dump_unused, which dumps the contents of | |
2364 | all unused blocks to stdout. (Useful as an emergency try-to-find | |
2365 | deleted data command.) | |
2366 | ||
2367 | Added a new debugfs command, imap, which prints the location of a | |
2368 | specified inode in the inode table. | |
2369 | ||
2370 | Fixed a bug in the badblocks program which caused it to use one bit of | |
2371 | randomness in its non-destructive read/write test, instead of using a | |
2372 | full 8 bits of randomness. | |
2373 | ||
2374 | Added a new option (-t) to badblocks, which allows the user to control | |
2375 | the test pattern(s) used when checking a disk. | |
2376 | ||
2377 | The blkid probe function now more correctly detects UDF filesystems. | |
2378 | ||
2379 | Fixed a bug in the blkid library which caused it to not update its | |
2380 | cache if a filesystem changes from having a label to not having a | |
2381 | label. | |
2382 | ||
2383 | Fixed a bug in the blkid library wihch could avoid an infinite loop | |
2384 | in blkid_find_dev_with_tag() if /proc is not mounted and there the | |
2385 | /etc/blkid.tab file has not yet been created. | |
2386 | ||
2387 | Fixed the badblocks program so that the destructive read/write test | |
2388 | honors the -c option, and to use O_DIRECT when possible to avoid | |
2389 | thrashing the system block buffer cache. | |
2390 | ||
2391 | Fixed various NLS issues. | |
c8a40402 | 2392 | - Added Czech and Swedish translations |
9c7ec178 TT |
2393 | - Removed testing NYC translation |
2394 | - Fixed NLS support for message abbrevations in e2fsck | |
2395 | - Remove de-utf.po, since we shouldn't have two versions using different | |
2396 | charset encodings. | |
2397 | - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to | |
2398 | simplify the statistics reporting in e2fsck. | |
2399 | ||
2400 | Changed configure.in so that its defaults for *BSD systems no longer | |
2401 | build an fsck wrapper, and not to install in /usr/local by default. | |
2402 | ||
2403 | Fixed some minor spelling errors/typo's in e2fsck and the configure | |
2404 | script. | |
2405 | ||
2406 | Fixed various Debian packaging issues (see debian/changelog). | |
2407 | ||
2408 | Updated and clarified man pages. (Addresses Debian Bug #195616) | |
2409 | ||
2410 | Programmer's notes: | |
2411 | ------------------- | |
2412 | ||
2413 | Fix gcc -Wall nitpicks. | |
2414 | ||
2415 | Updated gettext implementation used by e2fsprogs to 0.11.5, and enable | |
2416 | NLS support by default. (Added partial workaround for gettext/Darwin | |
2417 | incompatibility problems.) | |
2418 | ||
2419 | Added full MIT KRB5 and Himdall compaibility support to the com_err | |
2420 | library and the compile_et program. (Addresses Debian bug #191900) | |
2421 | ||
2422 | Added the blkid_known_fstype() function to the blkid library, which | |
2423 | returns true if it is passed a filesystem type which is recognized by | |
2424 | the blkid probing functions. | |
2425 | ||
2426 | Improved the documentation for the blkid library. | |
2427 | ||
2428 | Added the ext2fs_get_device_sectsize() function the the ext2fs library, which | |
2429 | returns the hardware sector size of a device, if it is available. | |
2430 | ||
2431 | Added a dependency in the blkid library's .so file to the uuid | |
2432 | library, since the former uses the latter. (Addresses Debian bug | |
2433 | #194094) | |
2434 | ||
2435 | Added --with-diet-libc and --disable-evms to the configure script. | |
2436 | ||
2437 | Fixed a minor memory leak in the badblocks program. | |
2438 | ||
2439 | Fixed a portability problem in tune2fs --- not all systems have strptime(). | |
2440 | ||
2441 | Fixed a portability problem in debugfs with the use of getopt() more | |
2442 | than once. Old-style BSD, new-style BSD, and Linux C libraries all do | |
2443 | things differently. | |
2444 | ||
2445 | Add support Windows support to ext2fs_get_device_size(). | |
2446 | ||
2447 | Added (normally disabled) debugging code to the Unix I/O manager which | |
2448 | causes it to disable all userspace caching if the NO_IO_CACHE is | |
2449 | defined. | |
2450 | ||
2451 | Changed the test I/O manager so it can always be linked into e2fsck, | |
2452 | mke2fs, and tune2fs if enabled via --enable-test-io-debug to the | |
2453 | configure script. The test I/O manager will only print any debugging | |
2454 | information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment | |
2455 | variables are set, which specifies which I/O operations are logged and | |
2456 | a block number to watch, respectively. The log messages are sent to | |
2457 | stderr by default, unless a filename is specified via the | |
2458 | TEST_IO_LOGFILE environment variable. | |
2459 | ||
2460 | ||
71df0dc3 | 2461 | E2fsprogs 1.33 (April 21, 2003) |
9c7ec178 | 2462 | =============================== |
508d7f3c | 2463 | |
ba142c1b TT |
2464 | Added a new utility program, logsave, which captures the output of a |
2465 | command in a log file, even if the containing directory hasn't been | |
2466 | mounted yet (in which case the it saves the output in memory until it | |
2467 | can write out the logfile). This is useful for capturing the | |
2468 | output of fsck during the boot sequence. | |
2469 | ||
2470 | Fixed some portability problems that were causing problems under | |
2471 | the Cygwin32 environment. | |
2472 | ||
2473 | Mke2fs now interprets a negative number to the -b option as a minimum | |
2474 | block size. | |
2475 | ||
2476 | Fixed a bug in mke2fs which was incorrectly checking the argument to | |
2477 | the -g option if the default block size was used. (Addresses Debian | |
2478 | bug #188319) | |
2479 | ||
2480 | Fsck now explicitly ignores tmpfs and devpts, and it will complain if | |
2481 | it can not find filesystem checkers for jfs, reseirfs, and xfs. | |
2482 | ||
2483 | E2fsck now updates the global free block and inode counters from the | |
2484 | block group specific counters quietly. This is needed for an | |
2485 | experimental patch which eliminates locking the entire filesystem when | |
2486 | allocating blocks or inodes; if the filesystem is not unmounted | |
2487 | cleanly, the global counts may not be accurate. | |
2488 | ||
2489 | Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS | |
2490 | 2.0 is not yet supported; this only pulled in the bug fixes: fixed | |
2491 | possible hangs caused by bugs in calling waitpid, and not setting the | |
2492 | pipe to non-blocking mode; also fixed a file descriptor leak; made | |
2493 | sure all functions call log entry/exit functions.) | |
2494 | ||
2495 | Badblocks now flushes its output file as bad blocks are discovered. | |
2496 | ||
2497 | The uuid library is now more paranoid about assuming the correctness | |
2498 | of the /dev/random device; it mixes in a stream of bytes from | |
2499 | random/srandom, just in case. | |
2500 | ||
39d38b05 | 2501 | Update Debian files to reflect the fact that I am now the Debian |
ba142c1b TT |
2502 | maintainer of e2fsprogs. Other various Debian-specific packaging |
2503 | cleanups. | |
39d38b05 TT |
2504 | |
2505 | Move the source tarball generation functions from the top-level | |
2506 | makefile to the util/gen-tarball script. | |
2507 | ||
2508 | Updated the Turkish .po translation file. | |
2509 | ||
1daf7585 | 2510 | Added Heimdal and MIT krb5 extensions to the com_err library to make |
39d38b05 TT |
2511 | it more compatible with com_err libraries from those distributions. |
2512 | ||
2513 | Changed dumpe2fs to always display the superblock fields relating to | |
2514 | the journalling and/or directory indexing feature even if those | |
2515 | features are not enabled. | |
2516 | ||
508d7f3c TT |
2517 | Updated and clarify copyright statement vis-a-vis alpha releases of |
2518 | e2fsprogs. | |
2519 | ||
2520 | The ss library will now try to dynamically link to the readline | |
2521 | library and use it if it is present in the system. This means that | |
ba142c1b TT |
2522 | the debugfs program now has line editing and history features. The |
2523 | SS_READLINE_PATH environment variable is used to find a readline or | |
2524 | readline-compatible library. | |
3809bf1d | 2525 | |
e5dced7f TT |
2526 | E2fsck now finds most duplicate filenames (all when rebuilding all |
2527 | directories via the -D option) and offers to delete or rename | |
2528 | duplicate filenames/directory entries. (Addresses Debian Bug #176814). | |
2529 | ||
2530 | Fix bug in e2image. When writing out a raw image file, include data | |
2531 | blocks from symlinks that do not store the symlink within the inode. | |
2532 | ||
3809bf1d TT |
2533 | Fix bug in resize2fs which incorrectly moved the block and inode |
2534 | bitmaps for sparse superblock filesystems and incorrectly marked | |
2535 | blocks as in use. (Addresses Debian bug #174766) | |
2536 | ||
2537 | Added a new shared library, the blkid library, which efficiently | |
2538 | allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL | |
2539 | and UUID filesystem specifiers without needing to search all of the | |
2540 | devices in the system. Instead, the device is looked up in a cache | |
2541 | file, and then verified to make sure the blkid cache is correct. | |
2542 | ||
2543 | Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for | |
2544 | the device name, using the blkid library. (Addresses Debian bugs | |
2545 | #166048, #179671) | |
2546 | ||
2547 | Fsck now supports backslash escapes in /etc/fstab so that \040 can be | |
2548 | used for spaces in device labels. | |
2549 | ||
2550 | Removed 32-bit limitations for debugfs's dump command. | |
2551 | ||
2552 | If the user specifies a large number of inodes, Mke2fs will | |
2553 | automatically adjust the number of blocks per group to find a valid | |
2554 | set of filesystem parameters. | |
2555 | ||
2556 | Add workaround to detect broken MD devices where when some of the | |
2557 | underlying devices are marked read-only, writes to the MD device are | |
2558 | silently dropped. E2fsck will detect if there is an attempt to run | |
2559 | the journal twice, and abort with an error if this is the case. | |
2560 | (Addresses IBM Bugzilla bug #1226) | |
2561 | ||
2562 | E2fsck will print an error if more than one of the -p/-a, -n or -y | |
2563 | options are specified. | |
2564 | ||
2565 | E2fsck will fix HTREE corruptions in preen mode, without stopping the | |
2566 | boot process. This is needed because the 2.4 ext2 filesystem | |
2567 | accidentally had the INDEX_FL backwards compatibility code removed. | |
2568 | ||
2569 | Mke2fs no longer creates filesystems with the dir_index flag set by | |
2570 | default; the user has to specifically request it. | |
2571 | ||
2572 | Update and clarified various man pages. (Addresses Debian bugs | |
ba142c1b | 2573 | #173612, #175233, #175113, and #170497, #185945, #188318) |
3809bf1d | 2574 | |
508d7f3c TT |
2575 | Created man page for the mk_cmds program (from the libss library). |
2576 | ||
3809bf1d TT |
2577 | Programmer's notes: |
2578 | ------------------- | |
2579 | ||
2580 | Fix various gcc -Wall nits. | |
2581 | ||
2582 | Fixed a lot of portability problems that caused e2fsprogs not to build | |
e5dced7f TT |
2583 | successfully under Solaris and Apple/Darwin. |
2584 | ||
2585 | Fixed a Makefile dependency to allow building e2fsprogs using parallel | |
2586 | make jobs. | |
3809bf1d TT |
2587 | |
2588 | Changes to create a subset distribution which consists only of the | |
2589 | et, ss, uuid, and blkid libraries. The configure script and top-level | |
2590 | makefile were changed to support working with a subset distribution. | |
2591 | ||
ba142c1b TT |
2592 | Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not |
2593 | actually used, and might people who are looking for | |
2594 | EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use. | |
2595 | ||
508d7f3c TT |
2596 | Updated debian files to fix a number of Lintian warnings. |
2597 | ||
2598 | Updated config.guess and config.sub with newer versions from the FSF. | |
3809bf1d | 2599 | |
71df0dc3 TT |
2600 | Removed unnecessary libraries from being linked into the fsck, lsattr, |
2601 | chattr, and blkid executables. | |
2602 | ||
38513011 TT |
2603 | E2fsprogs 1.32 (Nomvember 9, 2002) |
2604 | ================================== | |
2605 | ||
2606 | Fixed a bug in the Unix I/O routines which caused needless writebacks | |
2607 | of clean blocks from the unix_io cache (they were erroneously marked | |
2608 | as being dirty, so they were getting written back to disk before | |
2609 | getting evicted from the disk cache). This was harmless, but it | |
2610 | significantly slowed down e2fsck. | |
2611 | ||
2612 | Made some other minor optimizations to the Unix I/O routines to save a | |
2613 | small amount of CPU time. | |
2614 | ||
2615 | Updated internationalization files. | |
2616 | ||
3809bf1d | 2617 | |
ae65b29f TT |
2618 | E2fsprogs 1.31 (Nomvember 8, 2002) |
2619 | ================================== | |
2620 | ||
2621 | Update EVMS ext2fsim plugin with EVMS 1.2. (We still support | |
2622 | compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error | |
2623 | handling for child process that die unexpectly. Add a hack to force | |
2624 | mkfs to create filesystems that won't cause problems with hardware | |
2625 | that has 2k or 4k minimum blocksize requirements. Read from child | |
2626 | processes in non-blocking mode, so that the GUI continues to update. | |
2627 | ||
2628 | Fix e2fsck so that it returns the appropriate exit code when the root | |
2629 | filesystem has been changed, so that system's rc scripts will be told that | |
2630 | the system needs to be rebooted. | |
2631 | ||
2632 | Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag | |
2633 | was set, some of the descriptor blocks that should have been written | |
2634 | out were getting skipped. | |
2635 | ||
2636 | Changed e2fsck to force out changes to the backup copies of the | |
2637 | superblock and block group descriptors when important changes are made | |
2638 | to those data structures. | |
2639 | ||
2640 | Fix a bug where e2fsck could erroneously mark a filesystem as being | |
2641 | clean if a check of dirty filesystem is interrupted with a ^C. (Bug | |
2642 | introduced in e2fsprogs 1.28.) | |
2643 | ||
2644 | If journal debuging is enabled using --enable-jbd-debug, the debugging | |
2645 | level is now set via the E2FSCK_JBD_DEBUG environment variable. | |
2646 | ||
2647 | If byteswapping support is disabled using configure --disable-swapfs, | |
2648 | skip the tests which depend on byte-swapping, so that "make check" | |
2649 | won't bomb out. | |
2650 | ||
2651 | Lshattr will now display the indexed directory flag. Also, some of | |
2652 | the more esoteric compression flags are supressed unless compression | |
2653 | support has been enabled. | |
2654 | ||
2655 | Update man pages. | |
2656 | ||
2657 | ||
5d823a47 TT |
2658 | E2fsprogs 1.30 (October 31, 2002) |
2659 | ================================= | |
2660 | ||
2661 | When resizing a filesystem, and inodes need to moved, resize2fs will | |
2662 | update the inode's ctime field, and the mtime field of the containing | |
2663 | directories, so that incremental backups using dump/restore will work | |
2664 | correctly. | |
2665 | ||
2666 | In order to avoid spurious errors, e2fsck wil check the last | |
2667 | superblock write time to determine whether or not it can safely use | |
2668 | the LOW_DTIME checks to determine if there are inodes on the orphan | |
2669 | inode linked list that had somehow gotten disconnected. (Addresses | |
2670 | Sourceforge bug #620980) | |
2671 | ||
2672 | Partition in /proc/partitions that being with the string "lvm" are | |
2673 | considered real partitions even if they do not end with a number. | |
2674 | ||
2675 | Fixed a bug in the the uuid generation function, where if /dev/urandom | |
2676 | is not present, but /dev/random is, and there isn't sufficient | |
2677 | entropy, the get_random_byte function could spin a loop forever. | |
2678 | ||
2679 | E2fsck, mke2fs, etc. will now reliably notice when image files are | |
2680 | mounted using the loopback interface. (Addresses Sourceforge bug | |
2681 | #619119) | |
2682 | ||
2683 | When flushing buffers (as is done by badblocks, for example) check to | |
2684 | see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the | |
2685 | FDFLUSH ioctl which causes the MD device driver which causes confusing | |
2686 | syslog messages about obselete ioctl messages. (Addresses Sourceforge | |
2687 | bug #545832). | |
2688 | ||
2689 | Debugfs's write command now checks to see if the destination filename | |
2690 | exists before creating it. (Addresses Sourceforge bug #478195.) | |
2691 | ||
2692 | When installing man pages, search for compressed man pages using all | |
2693 | commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.) | |
2694 | ||
2695 | Fixed a bug in fsck where multiple filesystems specified on the | |
2696 | command were not being checked in parallel due to a logic bug | |
2697 | introduced to support the FSCK_MAX_INST environment variable. | |
2698 | ||
2699 | We have added a new superblock field, s_mkfs_time, which indicates | |
2700 | when a filesystem was created. It is set via mke2fs, and printed out | |
2701 | by dumpe2fs, but is not actually touched by the kernel. | |
2702 | ||
2703 | Dumpe2fs has been made more robust by not aborting if there is an | |
2704 | error reading the block/inode bitmaps; instead it will still print out | |
2705 | the location of the block/inode bitmaps and inode table. | |
2706 | ||
2707 | Add support for the an alternative block group descriptor layout which | |
2708 | allows for on-line resizing without needing to prepare the filesystem | |
2709 | in advance. (This is the incomat feature flag meta_bg.) | |
2710 | ||
2711 | Add support for storing default mount options in the superblock, so | |
2712 | that the filesystem can be mounted with specific mount options without | |
2713 | needing to specify them on the mount command line or in the /etc/fstab | |
2714 | file. | |
2715 | ||
2716 | Add support for a new inode flag, which is to be used for indicating | |
2717 | the top of directory hierarchies for the Orlov block allocator. | |
2718 | ||
2719 | Fix e2fsck so that if it creates the lost+found directory, it does so | |
2720 | with the more apporpriate permissions of 0700. Also change | |
2721 | mklost+found so that it also creates the directory 0700. | |
2722 | ||
2723 | Fixed format bug in e2fsck if NLS is in use. | |
2724 | ||
2725 | Add a German translation for e2fsprogs's NLS support. | |
2726 | ||
2727 | Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at | |
2728 | the beginning of the inode table. This won't matter much, since if | |
2729 | there is a bad block at the beginning of the inode table, the root | |
2730 | directory won't be available. But at least e2fsck won't crash in this | |
2731 | case. | |
2732 | ||
2733 | Fixed endian problems in the htree code for e2fsck and debugfs. | |
2734 | ||
2735 | When byte-swapping a filesystem on a PPC architecture, byte-swap the | |
2736 | bitmaps since the historical big-endian ext2 variant had byte-swapped | |
2737 | bitmaps, and the ext2fs library assumes this. This fixes the | |
2738 | regression test suite on PPC machines. | |
2739 | ||
2740 | Fix e2image so that it handles a bad block in the inode table | |
2741 | appropriately. | |
d5e7810e TT |
2742 | |
2743 | E2fsck now uses a more sophisticated algorithm to salvage corrupted | |
2744 | directories that recovers more information in the corrupted directory | |
2745 | block. | |
2746 | ||
2747 | E2fsck now performs additional consistency checks on indexed (HTREE) | |
2748 | directories. | |
2749 | ||
2750 | Fix bug where efsck might get confused about whether a completely | |
2751 | empty directory block is an empty leaf block or an interior htree | |
2752 | node. This could cause e2fsck to get confused into think that a valid | |
2753 | indexed directory was corrupted. | |
2754 | ||
2755 | E2fsck no longer creates an empty directory entry at the end of a | |
2756 | directory block when optimizing a directory. This would cause some | |
2757 | earlier versions of the dxdir kernel code to corrupt the directory | |
2758 | when attempting to split a node containing an empty directory entry. | |
2759 | ||
2760 | E2fsck could sometimes in rare circumstances leave the indexed flag | |
2761 | set after a small directory was optimized by compressing it instead of | |
2762 | indexing it. (This should never happen in real life, since | |
2763 | directories that small wouldn't have been indexed, but better safe | |
2764 | than sorry.) | |
2765 | ||
2766 | E2fsck now only updates the master superblock in all cases. This | |
2767 | slightly shortens its run time. | |
2768 | ||
2769 | Ext2ed can deal with directory entries of length 0; previously it | |
2770 | would get stuck in an infinite loop. | |
2771 | ||
2772 | Fsck now has support for reiserfs volumes when parsing LABEL= and UUID= | |
2773 | specifiers. (Sourceforge patch #613447) | |
2774 | ||
2775 | Badblocks will now work correctly on read-only devices such as | |
2776 | CD-ROM's. (Sourceforge patch #600451) | |
2777 | ||
5d823a47 | 2778 | Updated and clarified man pages. (Addresses Debian bug #167108) |

c6633059 TT |
2781 | E2fsprogs 1.29 (September 24, 2002) |
2782 | =================================== | |
2783 | ||
2784 | Fixed a bug in e2fsck which could corrupt a directory when optimizing | |
2785 | it (via the -D option) or rebuiliding the hash tree index with a 1 in | |
2786 | 512 probability, due to a fence post error. | |
2787 | ||
2788 | Fixed a bug in the LVM support code which caused LABEL='xxx' not to | |
2789 | work correctly. | |
2790 | ||
2791 | Mke2fs now enables the directory indexing flag by default. (Since | |
2792 | this is a compatible feature flag, it's safe to do so.) | |
2793 | ||
2794 | Tune2fs will support setting the directory indexing feature flag. It | |
2795 | will automatically set up the default hash algorithm and hash seed | |
2796 | fields in the superblock. | |
2797 | ||
2798 | If the bone-headed user enters the root filesystem twice in | |
2799 | /etc/fstab, the -R option which skips the root filesystem will skip | |
2800 | all of them. (Addresses Debian bug #159423). Note! This is not a | |
2801 | precedent for dealing intelligently with any other kind of doubled | |
2802 | entry in /etc/fstab! | |

2805 | Programmer's notes: | |
2806 | ------------------- | |
2807 | ||
2808 | Removed perror declaration in lib/et/internal.h. All modern systems | |
2809 | can be expected to define perror() these days. Besides, the lib/et | |
2810 | code wasn't using perror at all anyway. :-) | |

2813 | E2fsprogs 1.28 (August 31, 2002) |
2814 | ================================ | |
2815 | ||
2816 | Add support for the Hashed-Tree Directory Indexing to e2fsck. Support | |
2817 | for setting the htree flag is not included yet, although it can be | |
2818 | manually turned on via the debugfs program. | |
2819 | ||
2820 | Clarified e2fsck error message which is printed when it cannot find | |
2821 | sufficient contiguous block when relcating filesystem metadata. | |
2822 | ||
2823 | Added support for building an EVMS plugin module for ext2/3. This | |
2824 | module is substantially the same as the EVMS module shipping with EVMS | |
2825 | 1.1, with one or two bugfixes. E2fsprogs can also build this plugin | |
2826 | for use with EVMS 1.0 (which did not include the ext2 plugin module), | |
2827 | if the configure --enable-old-evms flag is given. | |
2828 | ||
2829 | Fsck will search through EVMS volumes when trying to resolve | |
2830 | filesystem specifications such as LABEL=xxx or UUID=xxx. | |
2831 | ||
2832 | Added a new utility program, /sbin/findfs, which will return | |
2833 | filesystem specifications such as LABEL=xxx or UUID=xxx, and prints | |
2834 | the device name. | |
2835 | ||
2836 | Update and clarified various man pages. (addresses Debian Bug #145044, | |
2837 | #146437, #131350, #151990, #144621, #141938) | |
2838 | ||
2839 | If there are no filesystems specified on fsck's command line, fsck now | |
2840 | treat that as if the -As options were given. Previously it would | |
2841 | simply do nothing. (Addresses Debian Bug #153102) | |
2842 | ||
2843 | Mke2fs no longer treats a failure to be able to clear the MD signature | |
2844 | at the end of the filesystem as a fatal error. (Addresses Debian Bug | |
2845 | #155007) | |
2846 | ||
2847 | The e2p library functions (which are used by lsattr and chattr) now | |
2848 | double check to make sure the file is a regular file or directory | |
2849 | before attempting to use the ext2 ioctls. Some device drivers | |
2850 | unfortunately respond to the ext2 ioctl's with unknown behaviour. | |
2851 | (Addresses Debian Bug #152029). | |
2852 | ||
2853 | The extended attribute handling has been updated to correspond with | |
2854 | the latest V2 bestbits ACL code. | |
2855 | ||
2856 | Fixed bug in e2fsck which caused it to not clear the dtime field when | |
2857 | processing truncated inodes on the orphan list. This could cause data | |
2858 | loss(!) if a filesystem is rebooted before a truncate has been | |
2859 | committed. | |
2860 | ||
2861 | E2fsck now uses red/black trees in pass1b, which removes some O(n**2) | |
2862 | algorithms. This makes e2fsck much faster in the case of severely | |
2863 | corrupted filesystems where a large number of blocks are claimed by a | |
2864 | large number of inodes. (Thanks to the 2.5 IDE device driver for | |
2865 | inspiring this work.) | |
2866 | ||
2867 | Resize2fs has been significantly sped up when shrinking and expanding | |
2868 | a filesystem by a very small number of blocks (for example, when EVMS | |
2869 | is converting a partition to be an EVMS legacy volume). | |
2870 | ||
2871 | Added a new option to e2fsck, -D, which will optimize or compress all | |
2872 | of the directories in the filesystem. | |
2873 | ||
2874 | E2fsck now catches SIGINT and SIGTERM to make sure it will can | |
2875 | properly clean up and only exit at safe points. Fsck will pass | |
2876 | SIGINT/SIGTERM to its child processes, and wait until they have all | |
2877 | exited before it exits. | |
2878 | ||
2879 | The uuid parsing code in the uuid library now properly complains when | |
2880 | an illegally formated uuid is presented to it. (Addresses Debian bug | |
2881 | #152891) | |
2882 | ||
2883 | Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 | |
2884 | and 2.4.17, since the workaround can cause problems when using a 2.4 | |
2885 | kernel with an old version of glibc built with the 2.2 headers. | |
2886 | ||
2887 | Fixed a bug in mke2fs where it wasn't properly clearing the initial | |
2888 | superblock used by other filesystems. (Addresses Debian bug #147256.) | |
2889 | ||
2890 | Added support for the synchronous directory feature written by Andrew | |
2891 | Morton. | |
2892 | ||
2893 | The debugfs program can delete directories using the rmdir command. | |
2894 | ||
2895 | Add support for 8k and 16k filesystems (for systems with page sizes | |
2896 | that are greater or equal to 8k or 16k, respectively). Note that | |
2897 | these filesystems can not be mounted on x86 systems, or other systems | |
2898 | with only 4k page sizes, due to limitations in the current Linux VM | |
2899 | code. | |
2900 | ||
2901 | Resize2fs requires that the filesystem state be valid and have no | |
2902 | errors; otherwise, e2fsck -f must be run first. (Previously it simply | |
2903 | required that the last fsck time be greater than the last mount time.) | |
2904 | ||
2905 | Configure now defaults the man pages directory to /usr/share/man on | |
2906 | Linux systems. | |
2907 | ||
2908 | E2fsck now offers to truncate inodes which contain too many blocks (so | |
2909 | that i_blocks would overflow. Also fixed handling of large sparse | |
2910 | files. | |
2911 | ||
2912 | E2fsck now more completely checks for symlink validity, including | |
2913 | requiring NULL termination and length checks. | |
2914 | ||
2915 | E2fsck will offer to try forcing a disk write to remap a bad block | |
2916 | after finding a read error when reading a filesystem metadata block. | |
2917 | ||
2918 | Fixed a bug in debugfs which caused the -b and -s options to crash | |
2919 | debugfs, as well as breaking the testb, setb, and clearb functions. | |
2920 | ||
2921 | Added a bmap command to debugfs which calculates the logical to | |
2922 | physical block mapping for a particular inode. | |
2923 | ||
2924 | Fixed a bug in code which checked to see if a device was mounted which | |
2925 | sometimes (rarely) failed in the case of a plain file. | |
2926 | ||
2927 | Fixed a bug in resize2fs where when it reported an error, it would | |
2928 | print a message erroneously indicating that the filesystem had been | |
2929 | resized before it aborted. | |
2930 | ||
2931 | When resizing a plain file which is smaller than the requested size, | |
2932 | resize2fs will attempt to extended the file so that programs like | |
2933 | e2fsck will not complain that the file is too small. | |
2934 | ||
2935 | Resize2fs will print the actual new size of the filesystem when it is | |
2936 | finished resizing. | |
2937 | ||
2938 | Fixed a bug in debugfs where "ls -l" would report incorrectl file type | |
2939 | information on big-endian systems. | |
2940 | ||
2941 | ||
2942 | Programmer's notes: | |
2943 | ------------------- | |
2944 | ||
2945 | Fixed collisions with C++ reserved words. | |
2946 | ||
2947 | Added portability fixes for building e2fsprogs on the HURD and AIX. | |
2948 | ||
2949 | Added the ext2ed program for creation of test cases. (ext2ed has many | |
2950 | limitations and bugs which make it unsuitable for production use.) | |
2951 | ||
2952 | The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new | |
2953 | flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the | |
2954 | name_len field is byte swampped on big-endian machines, since in the | |
2955 | V2 structure, name_len is a char field which is doesn't need to be | |
2956 | byte swapped --- except if an old-style kernel had byte-swapped the | |
2957 | name_len field as part of the V1 structure. | |
2958 | ||

2960 | E2fsprogs 1.27 (March 8, 2002) |
2961 | ============================== | |
2962 | ||
2963 | The warning messages for mke2fs now go to standard error. | |
2964 | ||
2965 | Fixed to make sure "make check" runs all of the test programs with | |
2966 | LD_LIBRARY_PATH set, so that we test the libraries in the build tree. | |
2967 | ||
2968 | The mke2fs program checks the boot sector for the BSD disk label, and | |
2969 | avoids erasing it if it is there. | |
2970 | ||
2971 | Fixed a bug in e2fsck which caused it to core dump if the journal | |
2972 | inode was missing when it was supposed to be there. | |
2973 | ||
2974 | E2fsck now prints ranges in pass 5 when printing deltas for the block | |
2975 | and inode bitmaps. | |
afa14ba0 TT |
2976 | |
2977 | Debugfs's "ls -l" command now will print out the file type information | |
2978 | in the directory entry. | |
2979 | ||
2980 | Create man pages and hard links for fsck.ext3 and mkfs.ext3. If | |
2981 | mke2fs is invoked as mkfs.ext3, create the filesystem with a journal. | |
2982 | ||
2983 | Debugfs can now examine the experimental directory indexing | |
2984 | information. | |
2985 | ||
a471ac52 TT |
2986 | Fixed bug in debugfs which caused it to core dump if modify_inode is |
2987 | called without an open filesystem. | |
2988 | ||
2989 | The debugfs lsdel command now runs its output through a pager first. | |
2990 | ||
afa14ba0 TT |
2991 | When installing manual pages, remove the compressed manual pages first. |
2992 | ||
2993 | Synchronized with Debian's packaging information for e2fsprogs-1.26-1. | |
2994 | ||
2995 | Fix the 2.4 resource limitation workaround introduced in 1.26 which | |
2996 | actually broke things on mips32, sparc32, and Alpha platforms. | |
2997 | ||
a471ac52 TT |
2998 | Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made |
2999 | (which is required by the newer libintl libraries). | |

3001 | Programmer's notes: |
3002 | ------------------- | |
3003 | ||
a8e77249 TT |
3004 | Fixed various gcc -Wall complaints. |
3005 | ||
afa14ba0 TT |
3006 | Fixed a few memory leaks in the e2fsck journaling code, and in the |
3007 | ismounted code checking for a swap device. | |
3008 | ||
3009 | Add new inode I/O abstraction interface which exports an inode as | |
3010 | an I/O object. | |
3011 | ||
3012 | Exported ext2_file_flush as a public interface. | |
3013 | ||
3014 | In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer. | |
3015 | ||
3016 | Lots of small random portability fixes to make e2fsprogs build under | |
3017 | AIX --- even without the 5L compatibility toolkit, and even using the | |
3018 | uber-crippled AIX native C compiler. | |

a5f3f5c1 | 3022 | ================================= |
cd1a79a5 | 3023 | |
446314fc TT |
3024 | Dumpe2fs will keep going now if the bad block inode can't be read. |
3025 | (Previously it stopped with a fatal error.) | |
3026 | ||
3027 | E2fsck will now give an opportunity to run the journal even if the | |
3028 | recovery flag is not set. This is the default behaviour if e2fsck is | |
3029 | using a backup superblock, since the needs_recovery flag will never be | |
3030 | set in the backup superblock copies. | |
3031 | ||
3032 | E2fsck now automatically finds the backup superblock/group descriptors | |
3033 | even when the primary superblock is completely destroyed for 2k and 4k | |
3034 | filesystems. (Previously it just guessed/assumed that we were dealing | |
3035 | with a 1k filesystem in that case, and users had to manually specify | |
3036 | the backup superblock number.) | |
3037 | ||
3038 | Fixed a bug in e2fsck where it dereferences a null pointer when there | |
3039 | is a problem opening a filesystem in preen mode. | |
3040 | ||
3041 | E2fsck now handles external journals correctly; previously it trashed | |
3042 | the external journal device if the journal needed to be replayed. | |
3043 | ||
3044 | Work around ulimit incompatibility problem caused by recent 2.4 | |
3045 | kernels; the unix IO module will automatically try to set any resource | |
3046 | limits to be infinite on startup. | |
3047 | ||
cd1a79a5 TT |
3048 | Fixed a bug in e2fsck where it wasn't allocating a new block or inode |
3049 | bitmap if it wasn't present and the blocksize was 2k or 4k. | |
9c7ec178 | 3050 | (Addresses Debian Bug #116975) |
cd1a79a5 TT |
3051 | |
3052 | E2fsck will check and fix botched ext3 V1 to V2 superblock updates by | |
3053 | clearing the new V2 fields if they do not make sense or if the ext3 | |
3054 | superblock is version 1 superblock. | |
3055 | ||
3056 | E2fsck will automatically relocate the ext3 journal from a visible | |
3057 | file (i.e., /.journal) to an hidden inode if the filesystem has been | |
3058 | opened read/write. This allows the users to add a journal while the | |
3059 | filesystem is mounted, but the next time the system is rebooted, the | |
3060 | journal file will disappear. This avoids problems with backups, | |
3061 | stupid operators with superuser bits, etc. | |
3062 | ||
3063 | Fix a bug in fsck where it would not support a filesystem type of | |
3064 | "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. | |
3065 | ||
a5f3f5c1 TT |
3066 | Fsck now supports fstab entries of the form "ext3,ext2". It will also |
3067 | automatically identify reiserfs filesystems. | |
3068 | ||
3069 | The number of processes spawned by fsck can now be limited using the | |
3070 | FSCK_MAX_INST environment variable. | |
3071 | ||
446314fc TT |
3072 | Fsck now searchs the LVM proc hierarchy to find logical volumes which |
3073 | should be searched for UUID and label information. | |
3074 | ||
cd1a79a5 TT |
3075 | Work around a bug in 2.4.10+ kernels by trying to unset the filesize |
3076 | limit if at all possible, when opening a block device. (The filesize | |
3077 | limit shouldn't be applied against writes to a block device.) | |
3078 | ||
446314fc TT |
3079 | In mke2fs and e2fsck, specifying the -c option twice will now do |
3080 | a read/write test on the disk. Update the man pages to encourage | |
3081 | using the -c option, and to discouraging running badblocks separately, | |
3082 | since users tend to forget to set the blocksize when running | |
3083 | badblocks. | |
3084 | ||
cd1a79a5 TT |
3085 | Mke2fs now automatically clears the immutable attribute on a |
3086 | pre-existing .journal file left over from a previous failed attempt to | |
3087 | add a journal to an alreadyy-mounted filesystem. | |
3088 | ||
3089 | Fixed mke2fs's exit codes to consistently indicate when the mke2fs | |
3090 | operation failed. | |
3091 | ||
446314fc TT |
3092 | Mke2fs now creates the lost+found directory with permissions of 0700, |
3093 | so that files that had previously lived in protected directory are | |
3094 | safe if they get dropped in lost+found and the system administrator | |
3095 | doesn't deal with immediately. (Addresses Debian #bug 118443) | |
3096 | ||
3097 | Mke2fs and e2fsck (and all programs that use the | |
3098 | ext2fs_check_if_mounted function) will now properly identify that a | |
3099 | device is mounted, even in cases where devfs has confused things with | |
3100 | multiple devices names with the same identity, or if a dim-witted | |
3101 | system administrator has done something stupid like creating device | |
3102 | file aliases in their home directory. Also now checks for swap devices | |
3103 | by using /proc/swaps. (Addresses Debian bug #106622) | |
3104 | ||
a5f3f5c1 TT |
3105 | Added a new option (-T) to tune2fs which sets the time a filesystem |
3106 | was last checked. | |
3107 | ||
cd1a79a5 TT |
3108 | Speed up e2image when creating sparse raw image files by optimizing |
3109 | away excess lseek() system calls. | |
3110 | ||
3111 | Fix support of large (> 2GB) files when used as a filesystem in | |
3112 | mke2fs, tune2fs, debugfs, and findsuper. | |
3113 | ||
3114 | Debugfs's stat and icheck commands now properly deals with large (> | |
3115 | 2GB) files. | |
3116 | ||
3117 | Debugfs's set_super_value command now prints out the list of valid | |
3118 | superblock fields which can be set using the command. | |
3119 | ||
446314fc TT |
3120 | Debugfs's rm and kill_file command now updates the superblock free block |
3121 | and inode counts, thus keeping the filesystem consistent. | |
3122 | ||
a5f3f5c1 TT |
3123 | Debugfs's lsdel command now takes an optional argument which allows |
3124 | the user to only see the most recently deleted files. | |
3125 | ||
3126 | A new command (undel) was added to debugfs which automates | |
3127 | undeleting a deleted inode and linking it back to a directory. | |
3128 | ||
3129 | Debugfs's ls command now takes a new option, -d, which lists | |
3130 | deleted directory entries. | |
3131 | ||
3132 | Debugfs's testb, freeb, setb, and find_free_block commands now take an | |
3133 | optional count argument. | |
3134 | ||
cd1a79a5 TT |
3135 | Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will |
3136 | be used to signal that a particular inode should not be eligible for | |
3137 | tail-merging --- this is needed for programs like LILO. | |
3138 | ||
3139 | The findsuper (an unreleased, uninstalled utility program) has been | |
3140 | improved to add extra validity checks and to add a progress meter. | |
3141 | (It is still an unsupported program; the officially supported way to | |
3142 | recover from a trashed partition table is to use gpart; findsuper is | |
3143 | for wizards only. :-) | |
3144 | ||
3145 | Debugfs was fixed to compile with "configure --disable-swapfs". | |
3146 | ||
446314fc | 3147 | Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) |
cd1a79a5 TT |
3148 | |
3149 | Added new translation file for Turkish. | |

3151 | Programmer's notes: |
3152 | ------------------- | |
3153 | ||
3154 | Fix general gcc -Wall complaints. | |
3155 | ||
3156 | E2fsprogs (mostly) works with the dietlibc. | |
3157 | ||
3158 | The programming texinfo file has been expanded to include description | |
3159 | of additional libext2fs functions. (Still not compeltely done, but a | |
3160 | lot of the more important functions have been documented.) | |
3161 | ||
3162 | Added a umask structure to struct_ext2_filsys, which currently only | |
3163 | modifies the behaviour of ext2fs_mkdir(), but if we add any file | |
3164 | creation functions to libext2fs, we should also make sure they respect | |
3165 | the umask setting. | |
3166 | ||
a5f3f5c1 TT |
3167 | The build-rpm script was fixed to be a bit more safe. |
3168 | ||
3169 | The tests' Makefile now has a way of automating test case creation | |
3170 | for e2fsck, using "make testnew". | |
3171 | ||
3172 | Created a new function, ext2fs_dir_iterate2 which passes more | |
3173 | information to the callback function (identical to the one used by | |
3174 | ext2fs_dblist_dir_iterate). The directory iterator functions take a | |
3175 | new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted | |
3176 | directory entries. If the directory entry is deleted, the callback | |
3177 | function will be called with the entry paraemter set to | |
3178 | DIRENT_DELETED_FILE. | |
3179 | ||
3180 | Added new functions, ext2fs_inode_alloc_stats and | |
3181 | ext2fs_block_alloc_stats, which takes updates block/inode allocation | |
3182 | statistics in the bitmaps, block group descriptors, and superblock | |
3183 | when inodes or blocks are allocated or deallocated. | |

3186 | E2fsprogs 1.25 (September 20, 2001) |
3187 | =================================== | |
3188 | ||
3189 | This is primarily a bug-fix release; no new features were added, but | |
3190 | there are a number of embarassing bug fixes and cleanups applied. | |
3191 | ||
3192 | Fix a bug mke2fs which causes stack garbage to be written to disk when | |
3193 | zapping disk sectors. (This bug could cause mke2fs to core dump for | |
3194 | some kernels, I suspect with security enhancement patches.) | |
3195 | ||
3196 | Remove unneeded #include of <linux/config.h> which was breaking | |
3197 | building e2fsprogs on the Hurd. (Addresses Debian bug #112414.) | |
3198 | ||
3199 | Updated tune2fs man page to reflect the fact that adding or removing a | |
3200 | journal doesn't require running e2fsck. | |
3201 | ||
3202 | Remove use of AC_REQUIRE from autoconf which had been used to prevent | |
3203 | AC_CANONICAL_HOST from being called twice; unfortunately this causes | |
3204 | recent autoconf to bomb out since they don't allow AC_REQUIRE to be | |
3205 | used outside of autoconf macros. Fortunately, it doesn't seem to be | |
3206 | necessary any more, anyway. | |
3207 | ||
3208 | E2fsck will now not fall back to an alternate superblock if the user | |
3209 | specifies the superblock location explicitly on the command-line. | |
3210 | This allows easier recovery from a situation where the primary | |
3211 | superblock and block groups are slightly corrupted, but the backup | |
3212 | superblocks are completely broken. | |
3213 | ||
3214 | Fix problem which caused compile_et and mk_cmds to blow up if | |
3215 | e2fsprogs was in a directory with a pathname that contained spaces. | |
3216 | ||
3217 | We are now more paranoid about checking the entry in /etc/mtab to make | |
3218 | sure the filesystem is really mounted, since some broken distributions | |
3219 | (read: Slackware) don't initialize /etc/mtab before checking non-root | |
3220 | filesystems. (Slackware also doesn't check the root filesystem | |
3221 | separately, and reboot if the root filesystem had changes applied to | |
3222 | it, which is dangerous and broken, but there's nothing I can do about | |
3223 | that.) | |
3224 | ||
3225 | Make UUID library C++ friendly by adding appropriate extern "C" | |
3226 | declarations and using const in the function declarations. | |
3227 | ||
3228 | Fix up the com_err texinfo file so that it can product a valid info | |
3229 | file (previously, it could only be used to generate paper | |
3230 | documentation using texinfo.tex). | |
3231 | ||

3233 | E2fsprogs 1.24a (September 2, 2001) |
3234 | =================================== | |
3235 | ||
3236 | Fix brown-paper bug in mke2fs which caused it to segfault when | |
3237 | printing the version string. | |
3238 | ||
3239 | ||
109624a1 TT |
3240 | E2fsprogs 1.24 (August 30, 2001) |
3241 | ================================ | |
3242 | ||
3243 | Revert the BLKGETSIZE64 support, since for some distributions, this | |
3244 | ioctl has been used by an unofficial kernel patch to update the last | |
3245 | sector on the disk, and this was causing disk corruption problems as a | |
3246 | result. | |
3247 | ||
3248 | Mke2fs is now more careful about zapping swap space signatures and | |
3249 | other filesystem/raid superblock magic values so that programs like | |
3250 | mount who try to use hueristics to determine the filesystem type of a | |
3251 | partition are less likely to be confused. | |
3252 | ||
3253 | E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a | |
3254 | regular file (since Andreas Dilger's on-line resizing tools will set | |
3255 | its mode bits). | |
3256 | ||
3257 | Fixed some minor texinfo, man pages nits for spelling errors, | |
3258 | texinfo warnings, etc. (Addresses Debian bug #110621.) | |
3259 | ||
3260 | E2fsprogs program no longer print the filesystem version number | |
3261 | (i.e. 0.5b), since it only confuses people and doesn't serve any real | |
3262 | purpose. | |
3263 | ||
3264 | E2fsck will once again compile under libc5, since it will supply its | |
3265 | own version of strnlen if necesssary. | |
3266 | ||
3267 | mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers | |
3268 | when specifying the external journal device. tune2fs will also search | |
3269 | devices looking for the externla journal debice when removing. | |
3270 | ||
3271 | E2fsprogs 1.23 (August 15, 2001) | |
3272 | ================================ | |
d1ef5c34 TT |
3273 | |
3274 | Add initial support for extended attributes (EA); e2fsck will | |
6c0a0417 TT |
3275 | correctly handle a filesystem with EA's and check the EA blocks for |
3276 | corruptions. | |
3277 | ||
d494bba8 TT |
3278 | E2fsck's symlink sanity checking has been cleaned up. It now checks |
3279 | the i_size value of fast symlinks, and checks for immutable flags | |
3280 | being set of symlinks, etc. | |
3281 | ||
c4ac9e14 TT |
3282 | E2fsck now offers to clear inodes which are special files that have a |
3283 | non-zero i_blocks or i_size field. (The i_size field check was in the | |
3284 | previous version of the code, but due to a bug it didn't offer to | |
3285 | clear the inode unless i_size and i_size_high were both non-zero.) | |
3286 | ||
d494bba8 TT |
3287 | E2image can now create "raw" image files, which only contain the |
3288 | filesystem metadata placed in a spare file so that e2fsck, dumpe2fs, | |
3289 | debugfs, etc., can be run directly on the raw image file. | |
bf16d106 TT |
3290 | |
3291 | Add support for the 64-bit block device patches. | |
3292 | ||
3293 | Fixed bugs in creating external journals with a 1k blocksize. | |
3294 | ||
d494bba8 TT |
3295 | Add initial support for external journals (so long as the external |
3296 | journal only supports a single filesystem) in e2fsck. | |
3297 | ||
3298 | Remove requirement for needing to run fsck on a filesystem after | |
3299 | removing a journal (either internal or external). | |
3300 | ||
bf16d106 | 3301 | The man pages now document how to create and manage external journals. |
d1ef5c34 TT |
3302 | |
3303 | Speed up the check of an ext3 filesystems by avoiding a needless flush | |
3304 | of all of the superblock and block group descriptors. | |
3305 | ||
d494bba8 TT |
3306 | Speed up creating an internal journal using tune2fs in the case where |
3307 | the filesystem has a lot blocks already allocated. | |
3308 | ||
c4ac9e14 TT |
3309 | Tune2fs has been fixed to make sure that only error messages go to |
3310 | stderr, and normal message go to stdout. (Addresses Debian bug #108555) | |
3311 | ||
d494bba8 | 3312 | Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will |
c4ac9e14 | 3313 | now not set the sparse_super feature. (Addresses Debian bug #108165) |
d494bba8 | 3314 | |
d1ef5c34 TT |
3315 | Add support in fsck for the filesystem type "auto". |
3316 | ||
c4ac9e14 TT |
3317 | Fsck -A will not try to interpret device names for filesystems which |
3318 | have a pass number is 0. (Addresses Debian bug #106696). | |
3319 | ||
3320 | Fsck prints a warning message if now valid filesystems are passed to | |
3321 | it. (Addresses Debian Bug #107458.) | |
3322 | ||
9249d980 TT |
3323 | E2fsck now gives an explicit warning if there filesystem still has |
3324 | errors at the end of the run. (Addresses Debian bug #104502) | |
3325 | ||
d494bba8 | 3326 | E2fsck will set the EXT2_ERROR_FS flag if the journal superblock |
c4ac9e14 TT |
3327 | reflects an error. E2fsck will also not run the orphan list if the |
3328 | filesystem contains errors, since the orphan list might be corrupted. | |
d494bba8 TT |
3329 | |
3330 | E2fsck now prints the number of large files when given the -v option. | |
3331 | ||
3332 | Fixed minor memory leaks in e2fsck. | |
bf16d106 | 3333 | |
c4ac9e14 | 3334 | Some minor man pages updates. (Addresses Debian bug #30833, #108174) |
9249d980 | 3335 | |

3337 | E2fsprogs 1.22 (June 22, 2001) |
3338 | ============================== | |
3339 | ||
3340 | Fixed a bug in e2fsck's handling of orphan inodes which are special | |
3341 | files (i.e., block/character device files, named FIFO's, etc.). | |
3342 | ||
3343 | Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused | |
3344 | tune2fs to fail at adding a journal to a mounted filesystem. | |
3345 | ||
3346 | Fixed a few big-endian bugs in e2fsprogs | |
3347 | * The directory block functions were accidentally reporting | |
3348 | some directories as corrupted when they weren't. | |
3349 | * If e2fsprogs is compiled --disable-swapfs, the C language | |
3350 | equivalents weren't being included for big-endian platforms. | |
3351 | (Fixes Debian bug #101686). | |
3352 | ||
3353 | Fixed a Hurd compilation problem. (Addresses Debian bug #101361) | |
3354 | ||
3355 | Programmer's notes: | |
3356 | ------------------- | |
3357 | ||
3358 | Use platform independent method of defining the BLKFLSBUF and FDFLUSH | |
3359 | ioctls, and allow them to be defined for non-i386 platforms. | |
3360 | ||
3361 | The uuid.h header file is now protected against multiple inclusions. | |
3362 | ||
3363 | E2fsprogs is now being developed using BitKeeper. Changed the test | |
3364 | scripts to deal with BK's stripping CR characgters from text files, | |
3365 | and changed the top-level Makefile.in to avoid including BitKeeper | |
3366 | files when generating the source tarball. | |
3367 | ||
3368 | ||
b90b826b TT |
3369 | E2fsprogs 1.21 (June 15, 2001) |
3370 | ============================== | |
3371 | ||
3372 | Added new configure flags which allow a subset e2fsprogs to be built; | |
3373 | this is most useful for boot floopies, since the resulting shared | |
3374 | libraries and programs are slimmed down by removing features that | |
3375 | aren't necessary for a boot floppy. The new flags that were added | |
3376 | are: --disable-swapfs, which removes support for byte swapping old | |
3377 | legacy PPC/68k filesystems, --disable-debugfs, which removes support | |
3378 | for debugfs from the libext2fs library, --disable-imager, which | |
3379 | removes support for the e2image program, and --disable-resizer, which | |
3380 | removes support for resize2fs. | |
3381 | ||
3382 | E2fsck now prints the number of mounts or days elapsed since the last | |
3383 | check when e2fsck is forced to check an otherwise clean filesystem. | |
3384 | ||
3385 | Tune2fs now prints an informative message about how often a filesystem | |
3386 | will be checked when adding a journal to the filesystem, to remind the | |
3387 | user that he/she may want to adjust those parameters using tune2fs | |
3388 | -c/-i. | |
3389 | ||
3390 | Worked around hurd brain-damage which causes e2fsck to sometimes | |
3391 | believe a filesystem is the root filesystem based on device numbers | |
3392 | (since Hurd doesn't have dev_t's, which is arguably a POSIX.1 | |
3393 | violation). | |
3394 | ||
3395 | Fixed a bug introduced in 1.20 which caused e2fsck to abort with an | |
3396 | erroneous error with the -F option was specified. | |
3397 | ||
3398 | Fixed a ext3 recovery bug in the revoke handling; synchronized with | |
c05b5521 TT |
3399 | ext3 0.7a. |
3400 | ||
767de097 TT |
3401 | Fixed two bugs in e2fsck's handling of dup block handling, dealing |
3402 | with relatively uncommon edge cases: a directory with an indirect | |
3403 | block which is claimed by another file, and when the last inode in the | |
3404 | filesystem has blocks claimed by another file. | |
3405 | ||
5a9c036b TT |
3406 | E2fsck now checks to see if the i_size field of a fast symlink is too |
3407 | big, and offers to clear the symlink if so. | |
3408 | ||
3409 | E2fsck now checks to see if i_size_high of special files is non-zero, | |
3410 | and offers to clear i_size_high. | |
3411 | ||
767de097 TT |
3412 | Fix e2fsck's handling of incompatible journal flags so that the user |
3413 | has chance to abort, and then has the option to clear out the journal | |
e333845b | 3414 | entirely. (Addresses Debian bug #98527.) |
767de097 | 3415 | |
b90b826b TT |
3416 | Fixed a bug in fsck which could cause it to core dump if a mix of |
3417 | standard and non-standard device names are used in /etc/fstab. | |
3418 | (Debian bug #100559) | |
3419 | ||
c05b5521 TT |
3420 | Fixed a bug in debugfs which caused read errors when copying a file to |
3421 | not be noticed. | |
3422 | ||
b90b826b TT |
3423 | The debugfs set_super_value command can now modify the s_lastcheck field. |
3424 | ||
c05b5521 TT |
3425 | Fixed a bug in lsattr and chattr which was accidentally introduced in |
3426 | 1.20 to support > 2GB files; both lsattr and chattr wasn't reading | |
3427 | directories correctly because the change modified the layout of struct | |
3428 | dirent to be incompatible with the libe2p shared library. | |
3429 | ||
b90b826b TT |
3430 | Cleaned up the mke2fs manual page and included a discussion about why |
3431 | it's good to periodically check the filesystem even when journaling is | |
3432 | enabled. | |
3433 | ||
767de097 TT |
3434 | Programmer's notes: |
3435 | ------------------- | |
3436 | ||
3437 | Fix general gcc -Wall complaints. | |
3438 | ||
3439 | The types needed by the ext2 header files are now provided by | |
3440 | lib/ext2fs/ext2_types.h, instead of include/asm/types.h. | |
3441 | ||
c05b5521 | 3442 | Integers are now preferred to longs when trying to find a 32-bit type |
b90b826b TT |
3443 | in ext2_types.h. Also, if linux/types.h has already been defined, |
3444 | don't try to redefine the types. | |
c05b5521 | 3445 | |
767de097 TT |
3446 | Fixed make depend script so that it automatically corrects the |
3447 | pathname cleanups performed by make -M, so I don't have to fix them up | |
3448 | by hand. | |
3449 | ||
3450 | Fixed the d_loaddump test case to be more robust, and not depend on | |
3451 | bash'isms. | |
3452 | ||
3453 | Removed debugfs's dependence on pread(), which was accidentally | |
3454 | intrudced in e2fsprogs 1.20 | |
3455 | ||
c05b5521 TT |
3456 | Fixed a performance bug in the libext2fs's icount routine; the size |
3457 | estimate of the icount array was incorrectly being calculated. | |
3458 | ||
b90b826b TT |
3459 | Removed use of the badblocks compatibility functions in the e2fsprogs |
3460 | programs. | |
3461 | ||
3462 | Added paranoia code which protects against strange cases where /etc | |
3463 | isn't on the root filesystem, or if /etc/mtab doesn't exist. | |
3464 | ||
3465 | The header file ext2_types.h is now installed. | |
3466 | ||
3467 | Autoconf is used to determine when we are on big-endian machines, | |
3468 | instead of doing run-time tests, to save a few bytes of code. | |
3469 | ||
3470 | The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap | |
3471 | functions are no longer inline functions, which saves space and | |
3472 | doesn't really cost any real performance. | |
3473 | ||
3474 | The ext2fs library no longer depends on the e2p library. (What need | |
3475 | there was of it --- namely, fsetflags, was coded in-line). | |
3476 | ||
3477 | Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even | |
3478 | when the user is stupid and tries compiling the package using "make | |
3479 | install" as root. | |
3480 | ||
3481 | Miscellaneous code cleanups: | |
3482 | * Added missing files from Makefile.in's SRCS file, so that | |
3483 | their dependencies would be properly calculated. | |
3484 | * Removed redundant code | |
3485 | * Fixed comments in code | |
3486 | * Removed no-longer unneeded argsused #pragma. | |
c05b5521 | 3487 | |
767de097 | 3488 | |
5a009bb9 | 3489 | E2fsprogs 1.20 (May 20, 2001) |
31d1d0c8 | 3490 | ============================= |
5570a65a | 3491 | |
31d1d0c8 TT |
3492 | Add support for replaying the ext3 journal purely in user mode, |
3493 | including handling the orphaned inode list. Used code contributed by | |
3494 | Andreas Dilger, with bug fixes and the orphaned inode handling done | |
3495 | by Theodore Ts'o. | |
3496 | ||
3497 | The mke2fs and tune2fs programs can create or modify a filesystem to | |
3498 | include an ext3 journal. Tune2fs also can be used to remove an ext3 | |
3499 | journal from a filesystem. | |
5570a65a TT |
3500 | |
3501 | E2fsck will now check for the existence of a linked list of orphan | |
3502 | inodes in the superblock, and clear those inodes before starting the | |
3503 | rest of the filesystem check (but after the journal playback). | |
3504 | ||
31d1d0c8 TT |
3505 | E2fsck now validates the file descriptor passed to the -C option, |
3506 | which saves against the completion bar getting written to an | |
3507 | unexpected location, such as the disk being checked. (Debian | |
3508 | bug/wishlist #55220) | |
3509 | ||
3510 | E2fsck will now bump the filesystem revision number from zero to one | |
3511 | if any of the compatibility bits are set. | |
3512 | ||
3513 | Fixed a bug where a badly corrupted directory on a big endian system | |
3514 | could cause e2fsck to die with a bus error. The | |
3515 | ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in | |
3516 | the ext2 library now does alignment sanity checks on the rec_len field | |
3517 | of the directory entry before using it. | |
3518 | ||
3519 | The ext2 library has been enhanced to make tune2fs safe to run on | |
3520 | mounted filesystems. (Users could usually get away with using tune2fs | |
3521 | on mounted filesystems before, but with the advent of ext3 and | |
3522 | journaling, it became important to make tune2fs was *really* safe for | |
3523 | use even when the filesystem being modified is mounted.) E2label is | |
3524 | now implemented by tune2fs using an argv[0] dispatch, so that e2label | |
3525 | is also now safe for use on mounted filesystems. | |
3526 | ||
3527 | Added a new program, e2image, which creates a backup of critical ext2 | |
3528 | filesystem data structures. The generated image file can be examined | |
3529 | using dumpe2fs and debugfs. In the future, e2fsck will be able to use | |
3530 | the image file to help recover very badly damaged filesystems. | |
3531 | ||
3532 | Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files | |
3533 | no longer cause e2fsck to bomb out. Also treat files > 2GB as being | |
3534 | large file when deciding whether or not the filesystem has large files. | |
3535 | ||
3536 | Fixed lsattr and chattr so that they work correctly on large files. | |
3537 | (Fixes Debian bug #72690.) | |
3538 | ||
3539 | Removed limitation in get_device_size() which imposed a one terrabyte | |
3540 | filesystem limitation. (Most 2.2 kernels still have a signed int | |
3541 | problem which cause 1 TB block device limitation. Fortunately, the | |
3542 | kernel patches to fix this are much easier than fixing the 2TB | |
3543 | limitation in the kernel. :-) | |
3544 | ||
3545 | A max_mount_count of zero is now treated as if no mount count were | |
3546 | set. (Previously, no mount count was indicated by using -1, and a | |
3547 | mount count of zero caused e2fsck to always be run.) | |
3548 | ||
77648565 | 3549 | Mke2fs supports two new filesystem types largefile and largefile4. |
31d1d0c8 TT |
3550 | |
3551 | Mke2fs now adds some randomness in s_max_mount_count so that multiple | |
3552 | filesystems won't be all checked at the same time under normal | |
3553 | operations. | |
3554 | ||
5570a65a TT |
3555 | Fixed bug in the progress bar printing code which could cause e2fsck |
3556 | to core dump on an illegal filesystem. | |
3557 | ||
31d1d0c8 TT |
3558 | Fixed bug in fsck which could allow more than one instance of e2fsck |
3559 | to be printing a progress bar. (Debian bug #65267) | |
3560 | ||
5570a65a TT |
3561 | Fsck using a UUID or a LABEL specifier will work even if devfs is |
3562 | compiled into the kernel and not mounted. If the pathnames in | |
3563 | /proc/partitions are incorrect, fsck will search /dev for the correct | |
3564 | device (using the new ext2fs_find_block_device library function). | |
3565 | Fsck now also checks the RAID devices first so that they are properly | |
31d1d0c8 TT |
3566 | found when they are in use. Support has also been added to support |
3567 | additional IDE disks and the DAC 960 device names. (Debian bug #94159) | |
3568 | ||
3569 | Fixed a bug in fsck which caused it not deal properly with 16 | |
3570 | byte long filesystem labels. | |
5570a65a | 3571 | |
5a009bb9 TT |
3572 | Fsck's -t option has been made a lot more flexible. The semantics for |
3573 | what happens if a comma-separated list to fsck has been regularized, | |
3574 | and it is now possible to filter what filesystems will get checked | |
3575 | based what is in the filesystem's fstab entry's option field. (Debian | |
3576 | bug #89483.) | |
3577 | ||
5570a65a TT |
3578 | The dumpe2fs program can now print out the group description |
3579 | information in hex, and also prints the location of the superblock and | |
3580 | block group descriptor for those block groups that have them. | |
3581 | ||
3582 | Mke2fs now clears the ext2 superblock before it starts creating a | |
3583 | filesystem, so that the superblock magic number is only written if the | |
3584 | filesystem creation process successfully completes. | |
3585 | ||
3586 | The debugfs program's stat command now pretty-prints the blocks used | |
3587 | by an inode so that it's more compact and informative. | |
3588 | ||
3589 | The debugfs stats command now uses the same libe2p code (which is used | |
3590 | by dumpe2fs) to print the superblock header information. This is more | |
3591 | complete, and it avoids a bit of code duplication. | |
3592 | ||
3593 | Added a new debugfs command, set_super_value (ssv) which allows the | |
3594 | user to set arbitrary superblock fields. | |
3595 | ||
31d1d0c8 TT |
3596 | Debugfs was extended to support inode numbers in hex (by prefixing |
3597 | them with 0x), and so that modify_inode can set the inode generation | |
3598 | number. Also, there is now a new function command called logdump | |
3599 | which will dump an ext3 journal. | |
3600 | ||
3601 | Fixed a bug in debugfs so that quitting out of the pager doesn't kill | |
3602 | debugfs. | |
3603 | ||
3604 | Debugfs's dump command now stops immediately upon reporting a disk | |
3605 | read error. (Fixed a bug in ext2fs_file_read library routine which | |
3606 | caused debugfs not to stop.) (Debian bug #79163) | |
3607 | ||
3608 | On systems with /proc/mounts (mainly Linux systems), /proc/mounts is | |
3609 | checked before /etc/mtab is used, since /proc/mounts is more likely to | |
3610 | be accurate. | |
3611 | ||
3612 | Added portability fixes for Solaris and Linux/ia64. | |
3613 | ||
3614 | Various manual pages were clarified and cleaned up. (Fixed debian | |
3615 | bugs #63442, #67446, and #87216) | |
3616 | ||
5570a65a TT |
3617 | |
3618 | Programmer's notes: | |
3619 | ------------------- | |
3620 | ||
3621 | The e2fsck message printer now supports %Iu and %Ig, which will print | |
3622 | out the inode's user and group owners, respectively. | |
3623 | ||
31d1d0c8 TT |
3624 | E2fsprogs now includes its own version of include/linux/ext2_fs.h, so |
3625 | that no longer dependent on the system having the correct version of | |
3626 | the kernel header files. | |
3627 | ||
5570a65a TT |
3628 | Added a new function to libext2, ext2fs_find_block_device(), which |
3629 | searches the system (i.e., /dev, /devfs, /devices) for a pathname to a | |
3630 | device given its device number. | |
3631 | ||
31d1d0c8 TT |
3632 | Added a new function to libext2, ext2fs_sync_device, which centralizes |
3633 | all of the places which might try to use the BLKFLSBUF or FDFLUSH | |
3634 | ioctls (and usually failing to define them since the system header | |
3635 | files don't usually do this for us, and we're trying to avoid usage of | |
3636 | kernel include files now). | |
3637 | ||
5570a65a TT |
3638 | Added new utility programs in tests/progs: random_exercise and |
3639 | hold_inode. They aren't built by default; they're useful for | |
3640 | exercising ext3 filesystem code. | |
3641 | ||
31d1d0c8 TT |
3642 | Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes |
3643 | the filesystem close functions to only update the superblock, and to | |
3644 | not touch the block group descriptors. Needed by tune2fs when | |
3645 | modifying a mounted filesystem. | |
3646 | ||
3647 | Got rid of struct ext2fs_sb and replaced it with the standard struct | |
3648 | ext2_super_block from include/linux/ext2_fs.h. Note: this may break | |
3649 | source (but not binary) compatibility of some users of the ext2 | |
3650 | library. Those applications should just simply do a global search and | |
7d614e3d TT |
3651 | replace of struct ext2fs_sb with struct ext2_super_block, and include |
3652 | the new header file <ext2fs/ext2_fs.h> which defines it. | |
31d1d0c8 TT |
3653 | |
3654 | The ino_t type has been renamed ext2_ino_t to protect applications | |
3655 | that attempt to compile -D_FILE_OFFSET_BITS=64, since this | |
3656 | inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an | |
3657 | unexpected ABI change. | |
3658 | ||
3659 | The Makefiles have been reworked so that "make check" can be run from | |
3660 | the top-level Makefile. | |
3661 | ||
3662 | Fix general gcc -Wall complaints and removed dead code. | |
3663 | ||
3664 | Remove use of NOARGS, because we assume everyone does ANSI C these | |
3665 | days. | |
3666 | ||
3667 | Added build-rpm script from sct. | |
3668 | ||
3669 | New functions ext2fs_image_{inode,super,bitmap}_{read,write} added | |
3670 | to support e2image. | |
3671 | ||
3672 | New function ext2fs_flush_icache which must be called if the | |
3673 | application program modifies the inode table blocks without going | |
3674 | through ext2fs_write_inode() interface. | |
3675 | ||
3676 | New ext2fs_check_mount_point() function, which will return the mount | |
3677 | point of a device if mounted. | |
3678 | ||
3679 | The io_channel abstraction now has an optional interface, | |
3680 | io_channel_write_range, which allows specific byte ranges to be | |
3681 | written. | |
3682 | ||
3683 | The unix_io IO channel now supports write-through caching, so that | |
3684 | journal creation is more efficient. | |
3685 | ||
3686 | Added x86 assembly language routines to support byte swapping, to | |
3687 | reduce executable size. | |
3688 | ||
3689 | Fixed bug in the utility program subst so that it's possible to | |
3690 | replace a substitution variable with a zero-length string. | |
3691 | ||
3692 | Fixed numbering e2fsck pass1 problem numbers; an extra zero had | |
3693 | slipped into some of the problem number. | |
5570a65a | 3694 | |
b777e26e TT |
3695 | E2fsprogs 1.19 (July 13, 2000) |
3696 | ============================== | |
ab146766 TT |
3697 | |
3698 | Release the resize2fs program since the timeout before it could | |
006ea71e | 3699 | be released under the GPL has finally expired. |
ab146766 TT |
3700 | |
3701 | Add experimental support needed for the ext2 compression patches. | |
3702 | This requires compiling e2fsprogs with the --enable-compression flag | |
3703 | to the configure script. | |
3704 | ||
3705 | Added ext3 journalling support. E2fsck will run the journal (if | |
3706 | necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is | |
3707 | installed as a symlink to e2fsck. Fsck has been taught about ext3, | |
3708 | and treats it the same as ext2 in terms of the progress bar logic. | |
3709 | Dumpe2fs will display the superblock journaling information if the | |
3710 | filesystem has a journal. The ext2 library will now permit opening an | |
3711 | ext3 filesystem with the recovery flag set. This is necessary for | |
3712 | on-line dump's to work correctly, but there may be issues with this | |
3713 | working well since ext3 is much less agressive about syncing blocks to | |
3714 | the filesystem, since they're safe on the journal. | |
3715 | ||
3716 | Tune2fs and e2fsck have been changed to allow the mount_count check to | |
3717 | be disabled by setting max_mount_count to -1. (This was already | |
3718 | supported by the kernel.) | |
3719 | ||
3720 | Create a symbolic link for fsck.ext3, since the e2fsprogs utilities | |
3721 | are used for ext3 as well. | |
3722 | ||
3723 | Added internationalization support for e2fsprogs; must be enabled | |
3724 | by passing --enable-nls to configure. | |
3725 | ||
3726 | Always use the provided ext2fs header files to insulate ourselves from | |
3727 | kernel version changes. Which include files are used by e2fsprogs | |
3728 | have also been cleaned up to improve portability. | |
3729 | ||
3730 | Limit the number of times that e2fsck updates the progress bar so that | |
3731 | people who are booting using a 9600 baud console don't get swampped by | |
3732 | too many updates. | |
3733 | ||
3734 | Improved the loop detection algorithm in e2sck's pass #3 so that it is | |
3735 | much, much faster for large filesystems with a large number of | |
3736 | directories. | |
3737 | ||
3738 | The memory footprint for e2fsck is now slightly smaller than before. | |
3739 | ||
3740 | E2fsck now checks if special devices have a non-zero size, and offers | |
3741 | to clear the size field if it finds such an inode. | |
3742 | ||
3743 | E2fsck now checks if special devices have the append-only flag set, | |
3744 | and offers to clear the inode. | |
3745 | ||
3746 | E2fsck now properly handles some "should never fail" cases during a | |
3747 | bitmap copy in pass5. | |
3748 | ||
3749 | E2fsck now properly prints control characters in filenames as ^A .. ^Z. | |
3750 | ||
31d1d0c8 TT |
3751 | E2fsck now calculates the correct location of the backup superblock in |
3752 | the case of filesystem blocksizes > 1k. | |
3753 | ||
3754 | Fixed a bug in e2fsck's calculation of the number of inodes_per_block | |
3755 | which normally didn't cause problems under most filesystem parameters, | |
3756 | but could cause a valid superblock to be rejected in extreme cases. | |
3757 | Other checks for validating superblock values were made more | |
3758 | stringent. | |
3759 | ||
ab146766 TT |
3760 | Added non-destructive write testing to the badblocks program, courtesy |
3761 | of David Beattie. The badblocks also now has an option to input the | |
3762 | current set of bad blocks, so that known bad blocks are skipped to | |
3763 | speed up the badblocks test. There is also a persistent rescan | |
006ea71e TT |
3764 | feature which causes badblocks to run until it has completed some |
3765 | number of passes without discovering any new bad blocks. | |
ab146766 TT |
3766 | |
3767 | Badblocks now checks to see if the device is mounted and refuses to do | |
3768 | the tests involving writing to the device if it is mounted. Also, | |
3769 | badblocks now allows the number of blocks to be checked to be | |
3770 | defaulted to the size of the partition. | |
3771 | ||
3772 | Fixed a bug in fsck which didn't allow non-root users to be able to | |
3773 | check filesystems if there were any LABEL= or UUID= entries in | |
3774 | /etc/fstab. | |
3775 | ||
3776 | The Hurd doesn't support the filetype filesystem feature. The mke2fs | |
3777 | program now makes sure that for the Hurd, the filestype feature is | |
3778 | turned off. E2fsck will check to see if the filetype feature is | |
3779 | turned on for Hurd filesystems, and offer to turn off the feature. | |
3780 | ||
3781 | Mke2fs now has a safety check to make sure the number of blocks do not | |
3782 | exceed 32 bits even on a 64 bit platform. | |
3783 | ||
3784 | Really fixed a bug in fsck to allow "fsck -As" to run interactive | |
3785 | fsck's. (For those people who like to do interactive fsck's in the | |
3786 | /etc/rc scripts!?!) | |
3787 | ||
3788 | Debugfs has a few new features: the rdump command, which will do a | |
3789 | recursive dump of a directory and all of its contents, and the lcd | |
3790 | command which does a local chdir (much like the ftp command of the | |
3791 | same name). In addition, the debugfs program and the open_filesystem | |
3792 | command now takes three new options: -b and -s, which allows the | |
3793 | blocksize and superblock location to be specified, and the -c option | |
3794 | which is used in catastrophic situations where the block group | |
3795 | descriptors are corrupt. If the -c option is specified, debugfs will | |
3796 | skip trying to read in the block and inode bitmaps. | |
3797 | ||
3798 | Debufs's lsdel command was fixed to handle bad blocks in the inode | |
3799 | table. | |
3800 | ||
3801 | A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use | |
3802 | 4 digit years. | |
3803 | ||
3804 | General improvements in error messages | |
3805 | ||
3806 | - Mke2fs prints a sane error message if the partition size is zero | |
3807 | (usually because the partition table wasn't reread by the | |
3808 | kernel due to the partition being busy), instead of "invalid | |
3809 | argument passed to ext2 library while initializing superblock". | |
3810 | ||
3811 | - Fsck now prints more self-explanatory message if an invalid UUID= | |
3812 | or LABEL= specification is passed to it. | |
3813 | ||
3814 | UUID library changed to use the LGPL. | |
3815 | ||
3816 | Fixed a bug in the UUID library where very rapid calls to the | |
3817 | time-based UUID generator could cause duplicate UUID's to be returned. | |
3818 | This was not a problem for e2fsprogs, but it could be a problem for | |
3819 | other users of the library. | |
3820 | ||
3821 | Make the UUID library more robust in the face of missing or an | |
3822 | improper /dev/urandom or /dev/random files. | |
3823 | ||
3824 | Added some random portability fixes for Solaris. | |
3825 | ||
3826 | Some minor man page updates. | |
3827 | ||
3828 | Fixed a memory leak in the ss library. | |
3829 | ||
3830 | ||
3831 | Programmer's notes: | |
3832 | ------------------- | |
3833 | ||
3834 | We now try to use lseek64 and open64 from the LFS if possible. | |
3835 | ||
3836 | The 3rd parameter in e2p's print_flags is now a flags word, instead of | |
3837 | a boolean option. | |
3838 | ||
3839 | The mark and unmark bitmap functions now return the previous state of | |
3840 | the bit that was being changed, which is useful for some speed | |
3841 | optimizations. | |
3842 | ||
3843 | The following functions have been added to enhance the badblocks list | |
3844 | handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and | |
3845 | ext2fs_badblocks_equal. | |
3846 | ||
3847 | The ext2 header files now have the latest journalling fields to the | |
3848 | superblock. | |
3849 | ||
3850 | The ext2fs_mkdir function in libext2fs now properly backs out of error | |
3851 | conditions robustly. | |
3852 | ||
3853 | Cleaned up makefiles: | |
3854 | - to cleanly compile with the -j flag. | |
3855 | - so distclean removes all generated files. | |
3856 | - so in case of an error while installing header files, the make aborts. | |
3857 | ||
3858 | Fix test_script so that it works correctly when compiling in the | |
3859 | source directory. | |
3860 | ||
31d1d0c8 TT |
3861 | The random UUID generation routine has been made slightly better in |
3862 | the case where /dev/random doesn't exist. (Use of randomly-based UUID | |
3863 | is still not recommended if /dev/random doesn't exist, however; it's | |
3864 | better to use the time/ethernet MAC address UUID in this case.) | |
ab146766 TT |
3865 | |
3866 | Clean up the build process so it's more friendly in case of missing | |
3867 | directories. | |
3868 | ||
3869 | The ext2fs header file can now be #include'd into C++ programs. | |
3870 | ||
3871 | The e2p.h header file is now installed. | |
3872 | ||
3873 | Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. | |
3874 | ||
3875 | ||
3876 | ||
24ded091 TT |
3877 | E2fsprogs 1.18 (November 10, 1999) |
3878 | ================================== | |
3879 | ||
3880 | Fix a core dumping bug in e2fsck if an imagic inode is present or | |
3881 | (more rarely) if the filesystem is badly corrupted enough that e2fsck | |
3882 | has to restart pass 1 processing. E2fsck now closes the filesystem | |
3883 | before freeing a large number of its data structures, so in the case | |
3884 | of future memory faults, at least the fixed filesystem will be fully | |
3885 | written out. | |
3886 | ||
3887 | If a filesystem doesn't support imagic inodes, and e2fsck discovers an | |
3888 | imagic inode, it will offer to clear the imagic flag. | |
3889 | ||
3890 | E2fsck will now offer to clear the immutable flag on special files | |
3891 | (device/socket/fifos) when running it in non-preen mode. | |
3892 | ||
3893 | E2fsck will now set the filetype when creating /lost+found, and when | |
3894 | connected orphaned inodes to /lost+found. | |
3895 | ||
3896 | Debugfs's ncheck and icheck commands now handles the case where there | |
3897 | are bad blocks in the inode table without bombing out. | |
3898 | ||
3899 | The badblocks list processing code has been made more efficiently for | |
3900 | appending a large number of (ordered) badblocks to the badblocks list. | |
3901 | ||
3902 | Some minor man page updates. | |
3903 | ||
3904 | Fsck now allows interactive e2fsck's when using fsck -As (not a common | |
3905 | mode, but some people like to do this in boot scripts for silly reasons). | |
3906 | ||
3907 | Programmer's notes: | |
3908 | ------------------- | |
3909 | ||
3910 | The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet | |
3911 | with the problem code convention. | |
3912 | ||
3913 | The badblocks list regression test program has been updated to work | |
3914 | with previously made API name changes. | |
3915 | ||
3916 | The ext2fs_free() command now uses the new badblocks API to avoid | |
3917 | using the compatibility layer. | |
3918 | ||
3919 | Added new regression test cases; the run_e2fsck test script now | |
3920 | supports the ability for a test case to run a prepratory command | |
3921 | before running e2fsck. | |
3922 | ||
28e1194e TT |
3923 | E2fsprogs 1.17 (October 26, 1999) |
3924 | ================================= | |
3925 | ||
3926 | Fixed nasty typo in fsck which caused parallelized fsck's to go into an | |
3927 | infinite loop. | |
3928 | ||
3929 | Fixed a bug in fsck where it used strncmp to compare a binary UUID, | |
3930 | thus potentially causing problems if a binary UUID contained a NULL | |
3931 | character. | |
3932 | ||
3933 | E2fsck now uses stricter checks for directory entries in pass 2: | |
3934 | zero-length filenames are not allowed; neither are 8 byte long | |
3935 | directory entries. | |
3936 | ||
3937 | The debugfs "dirty" command now clears the filesystem valid bit. | |
3938 | (Previously this just set the dirty-as-in-needs-writing-out-to-disk | |
3939 | bit in the in-core superblock image. The new functionality is more | |
3940 | what the user expects, and is more useful.) | |
3941 | ||
3942 | Added a debugging hook to test parallel fsck; if the environment | |
3943 | variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive | |
3944 | will be checked in parallel when they normally would not be. | |
3945 | ||
3946 | Programmer's notes: | |
3947 | ------------------- | |
3948 | ||
3949 | Fixed some #ifdef's for compilation under the Hurd OS. | |
3950 | ||
3951 | Fixed minor W2K compatibility problems. | |
3952 | ||
3953 | Fixed some miscellaneous GCC warnings. | |
3954 | ||
3955 | ||
8a31ffef TT |
3956 | E2fsprogs 1.16 (October 22, 1999) |
3957 | ================================= | |
3958 | ||
3959 | Fixed a race condition bug in fsck; when printing a progress bar, if | |
3960 | checking multiple filesystems in parallel, it was possible for fsck to | |
3961 | send e2fsck a SIGUSR1 signal before e2fsck had installed its signal | |
3962 | handler, which would cause it to terminate with a signal 10. | |
3963 | ||
3964 | E2fsck now properly handles filesystems that have the | |
3965 | INCOMPAT_FILETYPE feature turned on. It can be used to convert a | |
3966 | filesystem into using or not using FILETYPE feature. | |
3967 | ||
3968 | E2fsck now properly handles filesystems that have the IMAGIC feature | |
3969 | turned on (this is used on Linux AFS servers). | |
3970 | ||
3971 | The mke2fs program now creates filesystems that have the filetype and | |
3972 | sparse_superblock features enabled by default, unless it is run on a | |
3973 | pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, | |
3974 | so there is now a new flag -O which allows the user to specify with | |
3975 | which features she would like to create the filesystem; "mke2fs -O | |
3976 | none" will create a filesystsem compatible with 2.0 kernels. | |
3977 | ||
3978 | The tune2fs program now has a -O option which allows the user to set | |
3979 | and reset "safe" filesystem features. Currently, the only ones which | |
3980 | allows to be modified are the filetype and sparse_superblock features. | |
3981 | Note setting or clearing either feature will require running e2fsck on | |
3982 | the filesystem afterwards. (n.b. Clearing the sparse_superblock feature | |
3983 | requires that there is enough free space on the filesystem for the | |
3984 | extra superblocks which will be created by e2fsck.) | |
3985 | ||
3986 | Debugfs can now set and print filesystem features in the superblock | |
3987 | using the "features" command. Dumpe2fs will print out the complete | |
3988 | set of features when listing the superblock. | |
3989 | ||
3990 | Dumpe2fs has new options -f (force) and -h (header-only). | |
3991 | ||
3992 | Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead | |
3993 | message to come up. This could happen when decrementing or | |
3994 | incrementing a link count could result in an overflow. | |
3995 | ||
3996 | Fixed a bug in e2fsck where the block count on the lost+found | |
3997 | directory would not be properly incremented when the directory was | |
3998 | expanded to the point where an indirect block needed to be allocated. | |
3999 | ||
4000 | E2fsck now makes some additional sanity checks on the superblock to | |
4001 | avoid crashing or giving a memory allocation error if some of the | |
4002 | values in the superblock are unresonable (but the superblock otherwise | |
4003 | looks valid). | |
4004 | ||
4005 | Fixed a bug in e2fsck where a very badly corrupted filesystem might | |
4006 | require two passes to completely fix the filesystem. This happened if | |
4007 | an inode claimed blocks that was part of the filesystem metadata | |
4008 | (typically, when garbage was written into an inode table or indirect | |
4009 | block, since this kind of filesystem corruption normally doesn't | |
4010 | happen otherwise). | |
4011 | ||
4012 | On the Alpha, glibc declares st_flags although it isn't actually used; | |
4013 | the configure script was improved to detect this case so that | |
4014 | e2fsprogs can avoid using the non-functional stat field. | |
4015 | ||
4016 | The manual pages were updated to use a more consistent formatting | |
4017 | style consistent with standard Unix man pages. Mke2fs's man page | |
4018 | added documentation for a few previously undocumented options. | |
4019 | ||
4020 | Fixed minor display bugs in tune2fs and mke2fs. | |
4021 | ||
4022 | Programmer's notes: | |
4023 | ------------------- | |
4024 | ||
4025 | Improved portability of e2fsprogs to non-Unix systems (in particular, NT). | |
4026 | ||
4027 | Added features to parse and print feature strings into the e2p library. | |
4028 | (e2p_feature2string, e2p_string2feature, e2p_edit_feature). | |
4029 | ||
4030 | ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories | |
4031 | whose directory entries contain proper filetype information if the | |
4032 | filesystem supports it. | |
4033 | ||
4034 | ext2fs_link() now uses the low 3 bits of its flags parameter to pass | |
4035 | the directory entry filetype information. This is used to set the | |
4036 | directory entry filetype information if the filesystem supports it. | |
4037 | ||
4038 | Fixed a bug in ext2fs_expand_dir() where the block count in a | |
4039 | directory's inode would not be properly incremented when the directory | |
4040 | was expanded to the point where an indirect block needed to be | |
4041 | allocated. | |
4042 | ||
4043 | ||
a39f3efe | 4044 | E2fsprogs 1.15 (July 18, 1999) |
e2a99be6 | 4045 | ============================== |
6d53db3f TT |
4046 | |
4047 | Add configuration checks so that e2fsprogs will compile cleanly on | |
4048 | Linux 2.3 kernels that have renamed i_version to i_generation. | |
4049 | ||
e2a99be6 TT |
4050 | E2fsck now prints a progress/completion bar (and not just a simple |
4051 | spinner) if the -C0 option is requested or if it receives a SIGUSR1 | |
4052 | signal. Fsck will automatically manage the (potentially muliple) | |
4053 | e2fsck processes to print completion bars if it is given a -C option, | |
4054 | with the right thing happening if multiple filesystems are being | |
4055 | checked in parallel. | |
4056 | ||
4057 | Mke2fs now has better automatic hueristics to determine the filesystem | |
4058 | parameters to be used for a particular filesystem. Added a new option | |
4059 | -T which allows the user to specify how the filesystem is to be used, | |
4060 | which helps mke2fs do a better job selecting the filesystem parameters. | |
4061 | ||
a39f3efe TT |
4062 | Mke2fs now creates revision 1 filesystems by default, and with the |
4063 | sparse superblock feature enabled. The sparse superblock feature is | |
8a31ffef TT |
4064 | not understood by Linux 2.0 kernels, so they will only allow read-only |
4065 | mounts of filesystems with this sparse superblocks. | |
a39f3efe | 4066 | |
6d53db3f TT |
4067 | Fix bug where if /dev/null couldn't be opened (should never happen), |
4068 | e2fsck would hang in a tight loop. | |
4069 | ||
4070 | Make e2fsck handle the case where /lost+found isn't a directory. | |
4071 | ||
4072 | E2fsck now uses mallinfo if it exists to get accurate statistics about | |
4073 | its memory usage. | |
4074 | ||
4075 | Fix bug in e2fsck where it wouldn't check to see if a disconnected | |
4076 | inode had any problems before connecting it to /lost+found. | |
4077 | ||
4078 | Add check to e2fsck so it makes sure that total number of inodes in | |
4079 | the filesystem is a sane number. | |
4080 | ||
4081 | Fix fencepost error when clearing an the end of the block bitmap which | |
4082 | caused the last block in the bitmap not to get cleared. | |
4083 | ||
4084 | Cleaned up a number of messages in e2fsck: | |
4085 | * The message "Group's #'s copy of the group descriptor..." | |
4086 | was fixed so that the correct number would be displayed. | |
4087 | * Added missing space in the "disk write-protected" error messsage | |
4088 | * Cleaned up the error message printed when a non-interactive | |
4089 | e2fsck needs to abort a check because the filesystem | |
4090 | appears to be mounted. | |
4091 | ||
4092 | Added a new command-line utility, uuidgen, which will create and print | |
4093 | a UUID. | |
4094 | ||
4095 | Make debugfs's icheck command more robust by checking to make sure an | |
4096 | inode has valid blocks before interarting over the inode's blocks. | |
4097 | ||
4098 | UUID generation now uses a random-based scheme whenever possible to | |
4099 | prevent potential privacy problems. | |
4100 | ||
4101 | Man pages for all of the UUID functions in the lirbary were added. | |
4102 | ||
4103 | Fixed bug in fsck so it won't coredump if a filesystem not in | |
4104 | /etc/fstab is given to it. | |
4105 | ||
4106 | Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab | |
4107 | that most of the other mount utilities understands. | |
4108 | ||
4109 | Mke2fs will make a filesystem even if it appears mounted if the force | |
4110 | option is given. | |
4111 | ||
4112 | Dumpe2fs has new command-line options which allow a filesystem expert | |
4113 | to specify the superblock and blocksize when opening a filesystem. | |
4114 | This is mainly useful when examining the remains of a toasted | |
4115 | filesystem. | |
4116 | ||
4117 | The badblocks program has been updated to display correctly on disks | |
4118 | with large block numbers. | |
4119 | ||
e2a99be6 TT |
4120 | The badblocks program no longer gives spurious errors when errors |
4121 | occur on non-block boundaries, which is common if the blocksize is | |
4122 | larger than 1k. | |
4123 | ||
6d53db3f TT |
4124 | Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the |
4125 | MKE2FS_SYNC environment variable is set. This is to work around a VM | |
4126 | bug in the 2.0 kernel. I've heard a report that a RAID user was able | |
a39f3efe TT |
4127 | to trigger it even using a 2.2 kernel, but hopefully it will not be |
4128 | needed for most Linux 2.2 users. | |
6d53db3f TT |
4129 | |
4130 | Fixed miscellaneous documentation and man pages. | |
4131 | ||
4132 | Programmer's notes: | |
4133 | ------------------- | |
4134 | ||
4135 | Cleaned up functions such as pass1_get_blocks, pass1_read_inode which | |
4136 | in e2fsck's pass1.c really should have been static. | |
4137 | ||
4138 | The return value of the uuid_compare() function was changed to make it | |
4139 | match with the convetions used by strcmp, memcmp, and Paul Leach's | |
4140 | UUID sample document. | |
4141 | ||
4142 | The "make depend" process has now been made more automated; it now | |
4143 | automatically word-wraps the dependencies, and only replaces source | |
4144 | Makefile.in if there has been a change in the dependencies. Also, a | |
4145 | top-level "make depend" now recurses through all the subdirectories | |
4146 | automatically. | |
4147 | ||
4148 | The Makefile in .../util has been changed so that subst is built using | |
4149 | the native C compiler during a cross-compilation, since the subst | |
4150 | program is only used during the build process. Also add an explicit | |
4151 | rule to build util/subst by cd'ing to the correct directory and | |
4152 | running Makefile. | |
4153 | ||
4154 | The man directories are defined in terms mandir, so that the configure | |
4155 | script can override the location of the manual pages. | |
4156 | ||
4157 | The config files have been updated to recognize new machine types for | |
4158 | both the i386 and alpha families. | |
4159 | ||
4160 | Fsck has been modified so that it will accurately create an | |
4161 | fsck_instance even when the noexecute flag is set. This allows for | |
4162 | accurate debugging of the fsck pass structure. Also, when the verbose | |
4163 | flag is given twice, fsck will print debugging information about when | |
4164 | fsck is waiting for jobs to finish. | |
4165 | ||
4166 | ||
14790ed7 TT |
4167 | E2fsprogs 1.14 (January 9, 1999) |
4168 | ================================ | |
4169 | ||
4170 | Fix the fstab parsing code so that it can handle blank lines and | |
4171 | comment characters. Also, missing pass numbers need to be treated as | |
4172 | zero. | |
4173 | ||
4174 | Fixed a bug in e2fsck where under some circumstances (when e2fsck | |
4175 | needs to restart processing after fixing an egregious inconsistency) | |
4176 | it would try to access already freed memory. | |
4177 | ||
4178 | E2fsck now prints non-printable characters in directory entries and | |
4179 | pathnames using '^' and 'M-' notation. | |
4180 | ||
4181 | Fixed chattr so that it will ignore symbolic links when doing | |
4182 | recursive descent traversals. For both chattr and lsattr, no longer | |
4183 | print the version string unless the -V option is given. | |
4184 | ||
4185 | Allow the system administrator to directly specify the number of | |
4186 | inodes desired in the filesystem, for some special cases where this is | |
4187 | necessary. | |
4188 | ||
4189 | Fix portability problems so that e2fsprogs can be compiled under Linux | |
4190 | 1.2 systems and Solaris systems. | |
4191 | ||
4192 | Update the config.guess file with a more recent version that will | |
4193 | identify newer Linux platforms. | |
4194 | ||
4195 | Programmer's notes | |
4196 | ------------------ | |
4197 | ||
4198 | Ext2fs_read_inode and ext2fs_write_inode will now return an error if | |
4199 | an inode number of zero is passed to them. | |
4200 | ||
556ad132 TT |
4201 | E2fsprogs 1.13 (December 15, 1998) |
4202 | ================================== | |
4203 | ||
4204 | Fixed a bug in debugfs where an error messages weren't getting printed | |
4205 | when the ext2 library routines to read inodes returned errors in the | |
4206 | stat, cmri and rm commands. | |
4207 | ||
4208 | Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is | |
4209 | provided, it won't create an inode table smaller than the minimum | |
4210 | number of inodes required for a proper ext2 filesystem. | |
4211 | ||
4212 | Fsck now parses the /etc/fstab file directly (instead of using | |
4213 | getmntent()), so that it can distinguish between a missing pass number | |
4214 | field and pass number field of zero. This caused problems for | |
4215 | diskless workstations where all of the filesystems in /etc/fstab have | |
4216 | an explicit pass number of zero, and fsck could not distinguish this | |
4217 | from a /etc/fstab file with missing pass numbers. | |
4218 | ||
4219 | E2fsck will create a /lost+found directory if there isn't one in the | |
4220 | filesystem, since it's safer to create the lost+found directory before | |
4221 | it's needed. | |
4222 | ||
4223 | Fixed e2fsck so that it would detect bogus immutable inodes which | |
4224 | happen to be sockets and FIFO files, and offer to clear them. | |
4225 | ||
4226 | If a filesystem has multiple reasons why it needs to be checked, and | |
4227 | one of the reasons is that it is uncleanly mounted, e2fsck will print | |
4228 | that as the reason why the filesystem is being checked. | |
4229 | ||
4230 | Cleaned up the output routines of mke2fs so that it doesn't overflow | |
4231 | an 80 column display when formating really big filesystems. | |
4232 | ||
4233 | Added a sanity check to e2fsck to make sure that file descriptors 0, | |
4234 | 1, 2 are open before opening the hard disk. This avoids a problem | |
4235 | where a broken program might exec e2fsck with those file descriptors | |
4236 | closed, which would cause disastrous results if the kernel returns a | |
4237 | file descriptor for the block device which is also used by FILE * | |
4238 | stdout. | |
4239 | ||
4240 | Fixed up the e2fsck progress reporting functions so that the values | |
4241 | reliably reach 100% at the completion of all of the e2fsck passes. | |
4242 | ||
4243 | Fixed minor documentation bugs in man pages and usage messages. | |
4244 | ||
4245 | Programmer's notes: | |
4246 | ------------------- | |
4247 | ||
4248 | Fixed a number of lint warnings in the ext2fs library and potential | |
4249 | portability problems from other OS's header files that might define | |
4250 | CPP macros for names like "max" and "min". | |
4251 | ||
4252 | ext2fs_badblocks_list_add() has been made more efficient when it needs | |
4253 | to grow the bad blocks list. | |
4254 | ||
4255 | Fixed a bug in e2fsck which caused it to dereference a freed pointer | |
4256 | just before exiting. | |
4257 | ||
4258 | Fixed the substition process for generating the mk_cmds and compile_et | |
4259 | scripts so that they will work outside of the build tree. | |
4260 | ||
4261 | Add sanity check to e2fsck so that if an internal routine | |
4262 | (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer | |
4263 | and causing a core dump. This should never happen, but... | |
4264 | ||
a569671a | 4265 | E2fsprogs 1.12 (July 9, 1998) |
21d53850 TT |
4266 | ================================== |
4267 | ||
4268 | E2fsprogs now works with glibc (at least with the version shipped wtih | |
4269 | RedHat 5.0). The ext2fs_llseek() function should now work even with | |
4270 | i386 ELF shared libraries and if llseek() is not present. We also | |
4271 | explicitly do a configure test to see if (a) llseek is in libc, and | |
4272 | (b) if llseek is declared in the system header files. (See standard | |
4273 | complaints about libc developers don't understand the concept of | |
4274 | compatibility with previous versions of libc.) | |
4275 | ||
c9833a60 TT |
4276 | The ext2fs library now writes out the block group number in each of |
4277 | the superblock copies. This makes it easier to automatically | |
4278 | determine the starting block group of the filesystem when the block | |
4279 | group information is trashed. | |
4280 | ||
4281 | Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, | |
101c84f2 TT |
4282 | which means that e2fsprogs will ignore the high 8 bits of the |
4283 | directory entry's name_len field, so that it can be used for other | |
4284 | purposes. | |
4285 | ||
4286 | Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. | |
4287 | E2fsprogs will now support filesystems with 64-bit sized files. | |
4288 | ||
4289 | Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. | |
4290 | ||
21d53850 TT |
4291 | Added new program "e2label", contributed by Andries Brouwer. E2label |
4292 | provides an easy-to-use interface to modify the filesystem label. | |
4293 | ||
a4b2d3ce TT |
4294 | Fixed bug so that lsattr -v works instead of producing a core dump. |
4295 | ||
21d53850 TT |
4296 | Fixed a minor bug in mke2fs so that all groups with bad superblock |
4297 | backup blocks are printed (not just the first one). | |
a4b2d3ce TT |
4298 | |
4299 | Mke2fs will check the size of the device, and if the user specifies a | |
4300 | filesystem size larger than the apparent size of the device it will | |
4301 | print a warning message and ask if the user wants to proceed. | |
4302 | ||
c9833a60 TT |
4303 | E2fsck has a new option -C, which sends completion information to the |
4304 | specified file descriptor. For the most part, this is intended for | |
4305 | programs to use, although -C 0 will print a spinning character to the | |
4306 | stdout device, which may be useful for users who want to see something | |
4307 | happening while e2fsck goes about its business. | |
4308 | ||
21d53850 TT |
4309 | Fixed a bug in e2fsck which could cause a core dump when it needs to |
4310 | expand the /lost+found directory, and sometimes the bitmaps haven't | |
4311 | been merged in. Also fixed a related bug where ext2fs_write_dir_block | |
4312 | was used to write out a non-directory block. (Which would be bad on a | |
4313 | non-Intel platform with byte swapping going on.) | |
4314 | ||
4315 | Fixed bug in e2fsck where it would print a "programming error" message | |
4316 | instead of correctly identifying where a bad block was in used when | |
4317 | the bad block was in a non-primary superblock or block group | |
4318 | descriptor. Also fixed a related bug when sparse superblocks are in | |
4319 | use and there is a bad block where a superblock or block group | |
4320 | descriptor would have been in a group that doesn't include a | |
4321 | superblock. | |
4322 | ||
4323 | Fixed a bug in e2fsck (really in libext2fs's dblist function) where if | |
4324 | the block group descriptor table is corrupt, it was possible to try to | |
4325 | allocate a huge array, fail, and then abort e2fsck. | |
4326 | ext2fs_get_num_dirs() now sanity checks the block group descriptor, | |
4327 | and subsitutes reasonable values if the descriptors are obviously bogus. | |
4328 | ||
4329 | If e2fsck finds a device file which has the immutable flag set and the | |
4330 | i_blocks beyond the normal device number are non-zero, e2fsck will | |
4331 | offer to remove it, since it's probably caused by garbage in the inode | |
4332 | table. | |
4333 | ||
4334 | When opening a filesystem, e2fsck specially checks for the EROFS error | |
4335 | code, and prints a specific error message to the user which is more | |
4336 | user friendly. | |
4337 | ||
4338 | If the filesystem revision is too high, change the e2fsck to print | |
4339 | that this is either because e2fsck is out of date, or because the | |
4340 | superblock is corrupt. | |
4341 | ||
4342 | E2fsck now checks for directories that have duplicate '.' and '..' | |
4343 | entries, and fixes this corruption. | |
4344 | ||
4345 | E2fsck no longer forces a sync of the filesystem (with attendant sleep | |
4346 | calls) at all times. The ext2fs_flush() function now performs a sync | |
4347 | only if it needed to write data blocks to disk. | |
4348 | ||
4349 | Fixed a minor bug in e2fsck's pass1b's file cloning function, where | |
4350 | certain errors would not be properly reported. | |
4351 | ||
4352 | Updated and expanded a few points in the man pages which users | |
4353 | complained wheren't explicit enough. | |
4354 | ||
4355 | Added special case byte-swapping code if compiling on the PowerPC, to | |
4356 | accomodate the strange big-endian variant of the ext2 filesystem that | |
4357 | was previously used on the PowerPC port. | |
4358 | ||
4359 | ||
4360 | Programmer's notes: | |
4361 | ------------------- | |
4362 | ||
4363 | Removed C++ keywords from the ext2fs libraries so that it could be | |
4364 | compiled with C++. | |
4365 | ||
4366 | E2fsck's internal organization has now been massively reorganized so | |
4367 | that pass*.c don't have any printf statements. Instead, all problems | |
4368 | are reported through the fix_problem() abstraction interface. E2fsck | |
4369 | has also been revamped so that it can be called as a library from a | |
4370 | application. | |
4371 | ||
4372 | Added new fileio primitives in libext2fs for reading and writing | |
4373 | files on an unmounted ext2 filesystem. This interface is now used by | |
4374 | debugfs. | |
4375 | ||
4376 | Added a new libext2fs function for mapping logical block numbers of | |
4377 | a file to a physical block number. | |
4378 | ||
4379 | Added a new libext2fs function, ext2fs_alloc_block(), which allocates | |
4380 | a block, zeros it, and updates the filesystem accounting records | |
4381 | appropriately. | |
4382 | ||
4383 | Added a new libext2fs function, ext2fs_set_bitmap_padding(), which | |
4384 | sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. | |
4385 | ||
4386 | The libext2fs functions now use a set of memory allocation wrapper | |
4387 | functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, | |
4388 | instead of malloc, free, and resize. This makes it easier for us to | |
4389 | be ported to strange environments where malloc, et. al. aren't | |
4390 | necessarily available. | |
4391 | ||
4392 | Change the libext2fs fucntion to return ext2-specific error codes | |
4393 | (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using | |
4394 | and depending on the existence of system error codes (such as EEXIST | |
4395 | and ENOENT). | |
4396 | ||
4397 | Renamed io.h to ext2_io.h to avoid collision with other OS's header | |
4398 | files. | |
4399 | ||
4400 | Add protection against ext2_io.h and ext2fs.h being included multiple | |
4401 | times. | |
4402 | ||
4403 | The types used for memory lengths, etc. have been made more portable. | |
4404 | In generla, the code has been made 16-bit safe. Added Mark | |
4405 | Habersack's contributed DOS disk i/o routines. | |
4406 | ||
4407 | Miscellaneous portability fixes, including not depending on char's | |
4408 | being signed. | |
4409 | ||
4410 | The io_channel structure has a new element, app_data, which is | |
4411 | initialized by the ext2fs routines to contain a copy of the filesystem | |
4412 | handle. | |
4413 | ||
4414 | ext2fs_check_directory()'s callback function may now return the error | |
4415 | EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to | |
4416 | really do the checking, despite the presence of the callback function. | |
4417 | ||

4419 | E2fsprosg 1.11 (June 17, 1997) |
4420 | ============================== | |
4421 | ||
4422 | Fixed e2fsck to detect (previously ignored) conflicts between the | |
4423 | superblock or block group descriptors and block bitmaps, inode | |
4424 | bitmaps, and inode tables. | |
4425 | ||
4426 | Fixed bug in e2fsck so that when the message printed out when a block | |
4427 | or inode bitmap conflicts with other data, it has the correct group | |
4428 | number. | |
4429 | ||
4430 | Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed | |
4431 | to badblocks. This meant that not all of the filesystem was being | |
4432 | tested for bad blocks! | |
4433 | ||
4434 | Fixed an array boundary overrun case which cropped up in | |
4435 | ext2fs_badblocks_list_test when a user tried running "mke2fs -c | |
4436 | -b 4096". | |
4437 | ||
4438 | Adjusted the number of columns printed by mke2fs when displaying the | |
4439 | superblock backups to avoid running over 80 columns when making a | |
21d53850 | 4440 | really big filesystem. |
bc210074 TT |
4441 | |
4442 | Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, | |
4443 | dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar | |
4444 | fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). | |
4445 | ||
4446 | Programmer's notes: | |
4447 | ------------------- | |
4448 | ||
4449 | Fixed install rule in lib/ss so that ss_err.h is actually getting | |
4450 | installed. | |
4451 | ||
4452 | Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting | |
4453 | bassed back to the caller. | |
4454 | ||
4455 | Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been | |
4456 | setting the current inode number (which meant this function wasn't | |
4457 | working at all). | |
4458 | ||
4459 | Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all | |
4460 | blocks in the bitmap when increasing the size of the bitmap. | |
4461 | ||
4462 | Changed the initial number of blocks allocated by ext2fs_init_dblist() | |
4463 | to be more realistic. | |
4464 | ||
4465 | Added a new function ext2fs_allocate_group_table, which sets up the | |
4466 | group descriptor information (and allocates inode and block bitmaps, | |
4467 | and inode tables for a particular group). The function was created by | |
4468 | factoring out code form ext2fs_allocate_tables(). | |
4469 | ||
4470 | Added a new function ext2fs_move_blocks which takes a bitmap of the | |
4471 | blocks to be moved, and moves them to another location on the | |
4472 | boardboard. | |
4473 | ||
4474 | Make the unix_io channel's io_channel_flush implementation calls sync() | |
4475 | to to flush the kernel buffers to disk. | |
4476 | ||
4477 | Added a new function ext2fs_dblist_count returns the number of | |
4478 | directory blocks in dblist. | |
4479 | ||

4481 | E2fsprogs 1.10 (April 24, 1997) |
4482 | =============================== | |
4483 | ||
4484 | Mke2fs once again defaults to creating revision #0 filesystems, since | |
4485 | people were complaining about breaking compatibility with 1.2 kernels. | |
4486 | Warning messages were added to the mke2fs and tune2fs man pages that | |
4487 | the sparse superblock option isn't supported by most kernels yet (1.2 | |
4488 | and 2.0 both don't support parse superblocks.) | |
4489 | ||
4490 | Added new flag to mke2fs, -R <raid options>, which allows the user to | |
4491 | tell mke2fs about the RAID configuration of the filesystem. Currently | |
4492 | the only supported raid option is "stride" which specifies the width | |
4493 | of the RAID stripe. | |
4494 | ||
4495 | Fixed bug in e2fsck where pass1b would bomb out if there were any | |
4496 | blocks marked bad in the inode table. | |
4497 | ||
4498 | Fixed rare bug in mke2fs where if the user had a very unlucky number | |
4499 | of blocks in a filesystem (probability less than .002) the resulting | |
4500 | filesystem would be corrupt in the last block group. | |
4501 | ||
4502 | Fixed bug where if e2fsck tried to allocate a block to fix a | |
4503 | filesystem corruption problem and the filesystem had no free blocks, | |
4504 | ext2fs_new_block() would loop forever. | |
4505 | ||
4506 | The configure script now checks explicitly to see if "-static" works, | |
4507 | since that can't be assumed to be true --- RedHat doesn't install | |
4508 | libc-static by default. | |
4509 | ||
4510 | Fixed bug in libext2's block iterator functions where under some | |
4511 | cirmcustances, file with holes would cause the bcount parameter to the | |
4512 | callback function to be incorrect. This bug didn't affect any of | |
4513 | e2fsprogs programs, but it was discovered by Paul Mackerras, the | |
4514 | author of the PPC boot loader. | |
4515 | ||
4516 | Removed use of static variables to store the inode cache in libext2fs. | |
4517 | This caused problems if more than one filesystem was accessed via | |
4518 | libext2fs (static variables in libraries are generally a bad idea). | |
4519 | Again, this didn't affect e2fsprogs programs, but it was discovered by | |
4520 | Paul Mackerras. | |
4521 | ||
4522 | Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 | |
4523 | will compile cleanly with 1.2.13 kernels (even with a.out shared | |
4524 | libraries!) | |
4525 | ||
4526 | Programmer's notes: | |
4527 | ------------------- | |
4528 | ||
4529 | Added new functions to duplicate an ext2 filesystem handle, and its | |
4530 | associated substructure. New functions: ext2fs_dup_handle(), | |
4531 | ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). | |
4532 | Other structures, such as the io_channel and the inode_cache, now have | |
4533 | a ref count so that they only get freed when they are no longer used | |
4534 | by any filesystem handle. (These functions were added as part of the | |
4535 | development effort for an ext2 resizer). | |
4536 | ||
2ecc6fef TT |
4537 | E2fsprogs 1.09 (April 14, 1997) |
4538 | =============================== | |
4539 | ||
4540 | Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was | |
4541 | accidentally introduced in the 1.08 release. The overhead calculation | |
4542 | was accidentally removed, which caused ext2fs_initialize() to not | |
4543 | notice when the filesystem size needed to be adjusted down because | |
4544 | there wasn't enough space in the last block group. | |
4545 | ||
4546 | Fixed bug in version parsing library routine; it was always parsing | |
4547 | the library version string, instead of using the passed-in string. | |
4548 | ||
4549 | Clarified chattr man page. | |
4550 | ||
24757fa0 TT |
4551 | E2fsprogs 1.08 (April 10, 1997) |
4552 | =============================== | |
4553 | ||
4554 | E2fsck 1.07 was very slow when checking very large filesystems with a | |
4555 | lot of files that had hard links (i.e., news spools). This was fixed | |
4556 | by seriously revamping the icount abstraction. Added a formal test | |
4557 | suite for the icount abstraction. | |
4558 | ||
4559 | Debugfs now has a "-l" option to the "ls" command, which lists the | |
4560 | inode number, permissions, owner, group, size, and name of the files | |
4561 | in the directory. | |
4562 | ||
4563 | Fix a bug in e2fsck where when a directory had its blocks moved to | |
4564 | another location during the pass 1b processing, the directory block | |
4565 | list wasn't updated, so pass 2 wouldn't check (and correct) the | |
4566 | correct directory block. | |
4567 | ||
4568 | E2fsck will now treat inodes which contain blocks which are claimed by | |
4569 | the filesystem metadata by treating them as multiply claimed blocks. | |
4570 | This way, the data in those blocks can be copied to a new block during | |
4571 | the pass 1b--1d processing. | |
4572 | ||
4573 | E2fsck will attempt to determine the correct superblock number and | |
4574 | display it in the diagnostic and warning messages if possible. | |
4575 | ||
4576 | Add support for a new (incompatible) feature, "sparse_super". This | |
4577 | feature reduces the number of blocks which contain copies of backup | |
4578 | superblocks and block group descriptors. (It is only an incompatible | |
4579 | feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now | |
4580 | support a new -s option; e2fsck will recognize filesystems built with | |
4581 | this feature turned on. | |
4582 | ||
4583 | E2fsck now checks the library to make sure is the correct version, | |
4584 | using new library functions. (This helps to diagnose incorrectly | |
4585 | installed e2fsprogs distributions.) | |
4586 | ||
4587 | Dumpe2fs now prints more information; its now prints the the | |
4588 | filesystem revision number, the filesystem sparse_super feature (if | |
4589 | present), the block ranges for each block group, and the offset from | |
4590 | the beginning of the block group. | |
4591 | ||
4592 | Mke2fs now distributes the inode and block bitmap blok so that the | |
4593 | won't be concentrated in one or two disks in RAID/striping setups. | |
4594 | Also, if the user chooses a 2k or 4k block group, mke2fs will try to | |
4595 | choose the largest blocks per group that be chosen. (For 2k blocks, | |
4596 | you can have up to 16384 blocks/group; for 4k blocks, you can have up | |
4597 | to 32768 blocks/group.) Previously mke2fs would not allow | |
4598 | specification of more than 8192 blocks per group, even if you were | |
4599 | using a 2k or 4k block group. | |
4600 | ||
4601 | Programmer's notes: | |
4602 | ------------------- | |
4603 | ||
4604 | Added a new function ext2fs_create_icount2() which takes a "hint" | |
4605 | argument. This hint argument presets the icount array with the list | |
4606 | of inodes which actually need to be in the icount array. This really | |
4607 | helps to speed up e2fsck. | |
4608 | ||
4609 | Added a new function ext2fs_icount_validate() which checks the rep | |
4610 | invariant for the icount structure. This is used mostly for testing. | |
4611 | ||
4612 | The error mesasage given when a bad inode number is passed to | |
4613 | test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of | |
4614 | EXT2FS_UNMARK_ERROR). | |
4615 | ||
4616 | Added a new function ext2fs_set_dir_block which sets the block of a | |
4617 | dblist entry, given the directory inode and blockcnt. | |
4618 | ||
4619 | Added a new function ext2fs_get_library_version() which returns the | |
4620 | current library version, and ext2fs_parse_version_string() which | |
4621 | returns a version number based on a e2fsprogs version string. | |
4622 | ||
4623 | The icount functions will return EINVAL if the passed in inode number | |
4624 | is out of bounds. | |
4625 | ||
21c84b71 TT |
4626 | E2fsprogs 1.07 (March 9, 1997) |
4627 | ============================== | |
4628 | ||
4629 | E2fsck is now uses much less memory when checking really large | |
4630 | filesystems (or rather, filesystems with a large number of inodes). | |
4631 | Previously a filesystem with 1 million inodes required 4 megabytes of | |
4632 | memory to store inode count statistics; that storage requirement has | |
4633 | now been reduced to roughly half a megabyte. | |
4634 | ||
4635 | E2fsck can now properly deal with bad blocks appearing inside the | |
4636 | inode table. Instead of trying to relocate the inode table (which | |
4637 | often failed because there wasn't enough space), the inodes in the bad | |
4638 | block are marked as in use. | |
4639 | ||
4640 | E2fsck will automatically try to use the backup superblocks if the | |
4641 | primary superblocks have a bad magic number or have missing meta-data | |
4642 | blocks (or meta-data blocks which are out of range). | |
4643 | ||
4644 | E2fsck's pass 3 has been made more efficient; most noticeable on | |
4645 | filesystems with a very large number of directories. | |
4646 | ||
4647 | Completely revamped e2fsck's system of printing problem reports. It | |
4648 | is now table driven, to make them more easily customizeable and | |
4649 | extendable. Error messages which can be printed out during preen mode | |
4650 | are now one line long. | |
4651 | ||
4652 | Fixed e2fsck's filesystem swapping code so that it won't try to swap | |
4653 | fast symbolic links or deleted files. | |
4654 | ||
4655 | Fixed e2fsck core dumping when fixing a filesystem which has no | |
4656 | directories (not even a root directory). | |
4657 | ||
4658 | Added a check to e2fsck to make sure that the length of every | |
4659 | directory entry is a multiple of 4 (since the kernel complains if it | |
4660 | isn't). | |
4661 | ||
4662 | Added a check to e2fsck to make sure that a directory entry isn't a | |
4663 | link to the root directory, since that isn't allowed. | |
4664 | ||
4665 | Added a check to e2fsk to now make sure the '.' and '..' directory | |
4666 | entries are null terminated, since the 2.0 kernel requires it. | |
4667 | ||
4668 | Added check to write_bitmaps() to make sure the superblock doesn't get | |
4669 | trashed if the inode or block bitmap is marked as being block zero. | |
4670 | ||
4671 | Added checking of the new feature set fields in the superblock, to | |
4672 | avoid dealing with new filesystem features that this package wasn't | |
4673 | set up to handle. | |
4674 | ||
4675 | Fixed a fencepost error in ext2fs_new_block() which would occasionally | |
4676 | try to allocate a block beyond the end of a filesystem. | |
4677 | ||
4678 | When the UUID library picks a random IEEE 802 address (because it | |
4679 | can't find one from a network card), it sets the multicast bit, to | |
4680 | avoid conflicting with a legitimate IEEE 802 address. | |
4681 | ||
4682 | Mke2fs now sets the root directory's owner to be the real uid of the | |
4683 | user running mke2fs. If the real uid is non-zero, it also sets | |
4684 | the group ownership of the root directory to be the real group-id of | |
4685 | the user running mke2fs. | |
4686 | ||
4687 | Mke2fs now has more intelligent error checking when it is given a | |
4688 | non-existent device. | |
4689 | ||
4690 | When badblocks is given the -vv option, it now updates the block that | |
4691 | it is currently testing on every block. | |
4692 | ||
4693 | Fixed a bug in fsck where it wouldn't modify the PATH envirnoment | |
4694 | currently correctly if PATH wasn't already set. | |
4695 | ||
4696 | Shared libraries now built with dependencies. This allows the shared | |
4697 | library files to be used with dlopen(); it also makes the transition | |
4698 | to libc 6 easier, since ld.so can tell which libc a particular shared | |
4699 | library expects to use. | |
4700 | ||
4701 | Programmer's notes: | |
4702 | ------------------- | |
4703 | ||
4704 | Added new abstraction (defined in dblist.c) for maintaining a list of | |
4705 | blocks which belongs to directories. This is used in e2fsck and other | |
4706 | programs which need to iterate over all directories. | |
4707 | ||
4708 | Added new functions which test to see if a contiguous range of blocks | |
4709 | (or inodes) are available. (ext2fs_*_bitmap_range). | |
4710 | ||
4711 | Added new function (ext2_inode_has_valid_blocks) which returns true if | |
4712 | an inode has valid blocks. (moved from e2fsck code). | |
4713 | ||
4714 | Added new function (ext2fs_allocate_tables) which allocates the | |
4715 | meta-data blocks as part of initializing a filesystem. (moved from | |
4716 | mke2fs code). | |
4717 | ||
4718 | Added a new I/O manager for testing purposes. It will either allow a | |
4719 | program to intercept I/O requests, or print debugging messages to | |
4720 | trace the activity of a program using the I/O manager. | |
4721 | ||
4722 | The badblocks_list functions now store the bad blocks in a sorted | |
4723 | order, and use a binary search to speed up badblocks_list_test. | |
4724 | ||
4725 | The inode scan function ext2fs_get_next_inode() may now return a soft | |
4726 | error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in | |
4727 | those cases where part of an inode table is missing or there is a bad | |
4728 | block in the inode table. | |
4729 | ||
4730 | Added a new function (ext2fs_block_iterate2) which adds new arguments to | |
4731 | the callback function to return a pointer (block and offset) to the | |
4732 | reference of the block. | |
4733 | ||
4734 | Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an | |
4735 | application to jump to a particular block group while doing an inode | |
4736 | scan. | |
4737 | ||
4738 | The badblocks list functions were renamed from badblocks_* to | |
4739 | ext2fs_badblocks_*. Backwards compatibility functions are available | |
4740 | for now, but programs should be modified to use the new interface. | |
4741 | ||
4742 | Some of the library functions were reorganized into separate files to | |
4743 | reduce the size of some programs which statically link against the | |
4744 | ext2 library. | |
4745 | ||
4746 | Put in some miscellaneous fixes for the Alpha platform. | |
4747 | ||

4748 | |
4749 | E2fsprogs 1.06 (October 7, 1996) | |
4750 | ================================ | |
4751 | ||
4752 | Fixed serious bug in e2fsck: if the block descriptors are bad, don't | |
4753 | smash the backup copies in ext2fs_close(). (The problem was that when | |
4754 | e2fsck -p discovered the problem, while it was closing the filesystem | |
4755 | and exiting, it was also blowing away the backup superblocks on the | |
4756 | disk, which was less than friendly.) We now make it the case that we | |
4757 | only write out the backup superblock and the back block descriptors if | |
4758 | the filesystem is completely free from problems. | |
4759 | ||
4760 | Fixed a bug in block_interate in the lib/ext2fs library which caused | |
4761 | e2fsck to fail on GNU Hurd-created filesystems. | |
4762 | ||
4763 | Add support for Linux/FT's bootloader, which actually uses | |
4764 | EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want | |
4765 | to clear the inode. | |
4766 | ||
4767 | Add support for the "A" (no atime update) attribute. (Note: this | |
4768 | attribute is not yet in production kernels.) | |
4769 | ||
4770 | The test suite is not automatically run when doing a "make all" from | |
4771 | the top level directory. Users should manually run "make check" if | |
4772 | they wish to run the test suite. | |
4773 | ||
4774 | Upon a preenhalt(), make the printed message more explicit that | |
4775 | running e2fsck "MANAULLY" means without the -p or -a options. | |
4776 | ||
4777 | In e2fsck, if a disconnected inode is zero-length, offer to clear it | |
4778 | instead of offering to connect it to lost+found. | |
4779 | ||
4780 | In e2fsck, if a filesystem was just unmounted uncleanly, and needs | |
4781 | e2fsck to be run over it, change e2fsck to explicitly display this | |
4782 | fact. | |
4783 | ||
4784 | For dumpe2fs and e2fsck, cause the -V option to print out which | |
4785 | version of the ext2fs library is actually getting used. (This will | |
4786 | help detect mismatches of using a 1.06 utility with a 1.05 library, | |
4787 | etc.) | |
4788 | ||
4789 | Programmers' notes: | |
4790 | ------------------- | |
4791 | ||
4792 | EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits | |
4793 | the naming convention. | |
4794 | ||
4795 | In ext2fs_initialize(), make sure the description for the inode bitmap | |
4796 | is correctly initialize. | |
4797 | ||
4798 | Fixed minor type typo in ext2fs_allocate_generic_bitmap(); | |
4799 | ||
fc6d9d51 TT |
4800 | E2fsprogs 1.05 (September 7, 1996) |
4801 | ================================== | |
4802 | ||
4803 | Add support for new fields in the ext2 superblock --- volume name, | |
4804 | volume UUID, and last mounted field. Dumpe2fs displays these fields, | |
4805 | tune2fs and mke2fs allows you to set them. E2fsck will automatically | |
4806 | generate a UUID for those volumes that don't have them. | |
4807 | ||
4808 | Put in support for e2fsck to recognize HURD specific ext2 features --- | |
4809 | most notably, the translator block. The e2fsprogs tools will now use | |
4810 | the creator_os field in the superblock to correctly handle different | |
4811 | OS-specific variants of the ext2 filesystem. | |
4812 | ||
4813 | E2fsck now fixes inodes which have a the deletion time set, but which | |
4814 | have a non-zero i_link_count field by offering to clear the deletion | |
4815 | time. Previously e2fsck assumed that the inode was deleted (per 0.3c | |
4816 | ext2 kernel behavior) and offered to unlink the file. | |
4817 | ||
4818 | If e2fsck sets the clean bit, but nothing else, set the exit code | |
4819 | FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it | |
4820 | set the filesystem valid bit when it was previously cleared. :-) This | |
4821 | was needed to make the HURD fsck driver happy. | |
4822 | ||
4823 | If the user refuses to attach an unattached inode, e2fsck will no | |
4824 | longer set the inode's link count. Otherwise, the inode would end up | |
4825 | getting marked as unused, which might cause loss of data later. | |
4826 | ||
4827 | Make the message issued by e2fsck when the superblock is corrupt less | |
4828 | confusing for users. It now mentions that another reason for the | |
4829 | "corrupt superblock" message might be that the partition might not be | |
4830 | an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) | |
4831 | ||
4832 | Make the libext2 library more robuest so that e2fsck won't coredump on | |
4833 | an illegal superblock where the blocksize is zero. (f_crashdisk is | |
4834 | the test case). | |
4835 | ||
4836 | By default, create filesystems where the default checkinterval is 6 | |
4837 | months (180 days). Linux servers can be robust enough that 20 reboots | |
4838 | can be a long, long time. | |
4839 | ||
4840 | Added configure flag --enable-old-bitops, which forces the bitops to | |
4841 | use the old (native) bitmask operations. By default on the sparc | |
4842 | platform, the standard ext2 bit ordering is now used. | |
4843 | ||
4844 | Added a new feature to e2fsck to byte-swap filesystems; this can be | |
4845 | used to convert old m68k filesystems to use the standard byte-order | |
4846 | storage for the superblock, inodes, and directory blocks. This | |
4847 | function is invoked by using the '-s' option to e2fsck. | |
4848 | ||
4849 | Debugfs's "dump" command has been enhanced so that it writes out the | |
4850 | exact size of the file so that the nulls at the end of the file are | |
4851 | eliminated. The command also accept a new "-p" option which will | |
4852 | attempt preserve to preserve the ownernship, permissions, and | |
4853 | file modification/access times. | |
4854 | ||
4855 | Debugfs has two new options, -f and -R. The -R option allows the user | |
4856 | to execute a single debugfs command from the command line. The -f | |
4857 | option allows the user to specify a "command file" containing debugfs | |
4858 | commands which will get executed. | |
4859 | ||
4860 | Dumpe2fs now pretty prints the check interval, instead of just | |
4861 | printing the check interval as a number of seconds. | |
4862 | ||
4863 | Fix bugs in debugfs: the params command when no filesystem is opened | |
4864 | no longer causes a core dump. It is now possible to unlink a file | |
4865 | when a pathame containing a '/' is specified. | |
4866 | ||
4867 | Tune2fs has a new -C option which sets the number of times the | |
4868 | filesystem has been mounted. | |
4869 | ||
4870 | Fix the chattr '-v' option so that it actually works. Chattr was | |
4871 | being buggy about the -v option parsing. | |
4872 | ||
4873 | Programmers' notes: | |
4874 | ------------------- | |
4875 | ||
4876 | The directory lib/uuid contains a set of library routines to generate | |
4877 | DCE compatible UUIDs. | |
4878 | ||
4879 | Extended ext2fs_namei() to handle symbolic links. Added new function | |
4880 | ext2fs_nami_follow() which will follow last symbolic link in the case | |
4881 | where the pathname points to a sym link. | |
4882 | ||
4883 | The ext2fs_block_iterate function will now return the HURD translator | |
4884 | block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the | |
4885 | iterator to return data blocks only. The ext2fs.h file now defines | |
4886 | constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and | |
4887 | BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block | |
4888 | count field of the iterator callback function. | |
4889 | ||
4890 | The test script driver now takes an optional second argument, which is | |
4891 | the test case to be run. This allows you to run a test case without | |
4892 | needing to run the entire test suite. | |
4893 | ||
4894 | On Linux ELF systems, install the .so files in the correct places | |
4895 | (/usr/lib). The .so files must be stored in the same directory as the | |
4896 | .a files. | |
4897 | ||
4898 | Fixed miscellaneous HURD compilation issues with header file being | |
4899 | included in the right order. | |
4900 | ||
4901 | Fixed debugfs so that it resets optind to zero, not one, since setting | |
4902 | optind to zero is more correct. | |

4905 | E2fsprogs 1.04 (May 16, 1996) |
4906 | ============================= | |
4907 | ||
4908 | First "official" (1.03 was a limited release only) to support building | |
4909 | e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 | |
4910 | kernels). | |
4911 | ||
4912 | This package includes a RPM specs file, that it can be built using the | |
4913 | RedHat Package Manager. | |
4914 | ||
4915 | E2fsck now prints a hint that if there are lots of incorrectly located | |
4916 | inode bitmaps, block bitmaps, and inode table blocks, the user might | |
4917 | want to try using e2fsck -b 8193 first, to see if that fares any | |
4918 | better. | |
4919 | ||
4920 | For ext2 filesystem written with the hurd, debugfs will now print out | |
4921 | the translator field when printing an inode structure. | |
4922 | ||
4923 | Lots of miscellaneous linking/installation cleanups: | |
4924 | ||
4925 | Libraries are now linked using a relative pathname, instead of | |
4926 | relying on -L working correct. It doesn't, in many cases, including | |
4927 | current versions of GNU ld. This guarantees that the build tree is | |
4928 | linking with the right libraries, instead of the ones installed in | |
4929 | /usr/lib. | |
4930 | ||
4931 | Header files, man pages, and the et/ss shell scripts are now | |
4932 | generated using a custom substitution script, instead of relying on | |
4933 | the configure script. This prevents needless recompilation of | |
4934 | files; in addition, the custom substitution script is much faster. | |
4935 | ||
4936 | e2fsck may now be linked dynamically, by using the | |
4937 | --enable-dynamic-e2fsck flag to configure. This is not recommended, | |
4938 | since it increases e2fsck's dependence on other files, but some | |
4939 | people need to save disk space, and other critical programs on their | |
4940 | systems were being linked dynamically anyway. | |
4941 | ||
4942 | Programs such as fsck which didn't need to be linked against | |
4943 | libext2fs (or mke2fs which didn't need to be linked against libe2p) | |
4944 | only link against libraries they actually need. Otherwise, those | |
4945 | programs would require the presense of libraries that otherwise | |
4946 | could be removed from a rescuse diskette. | |
4947 | ||
4948 | The ss include files are now installed correctly so they can | |
4949 | actually be used by another package. | |
4950 | ||
4951 | If the profiling libraries are built, they are now installed on a | |
4952 | "make install-libs". | |

4955 | E2fsprogs 1.03 (March 27, 1996) |
4956 | =============================== | |
4957 | ||
4958 | Change the m68k bit numbering for bitmasks to match the bit numbering | |
4959 | used by all other ext2 implementations. (This change was requested by | |
4960 | the m68k kernel development team.) | |
4961 | ||
4962 | Support (in-development) filesystem format revision which supports | |
4963 | (among other things) dynamically sized inodes. | |
4964 | ||
4965 | Fixed a bug in the ext2 library so that an intelligent error is | |
4966 | returned if mke2fs is run with a ridiculously small number of blocks | |
4967 | for a partition. | |
4968 | ||
4969 | Fixed a bug in the ext2 library which required that the device be | |
4970 | openable in read/write mode in order to determine its size. This | |
4971 | caused e2fsck -n to require read/write access when it was not | |
4972 | previously necessary. | |
4973 | ||
4974 | Fixed a bug in e2fsck which casued it to occasionally fail the test | |
4975 | suite depending on which version of the floating point library it was | |
4976 | using. | |
4977 | ||
4978 | Fixed a bug in e2fsck so that it now halts with a fatal error when | |
4979 | certain superblock consistency checks fail. Previously it continued | |
4980 | running e2fsck, with some potential confusing/damaging consequences. | |
4981 | ||
4982 | Added new flag to fsck which allows the root to be checked in parallel | |
4983 | with other filesytems. This is not the safest thing in the world to | |
4984 | do, but some system administrators really wanted it. | |
4985 | ||

4986 | Fixed -Wall flames in lib/ss. |

4988 | |
4989 | E2fsprogs 1.02 (January 16, 1996) | |
4990 | ================================= | |
4991 | ||
4992 | Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. | |
4993 | ||
4994 | Change e2fsck to print statistics of how many non-contiguous files are | |
4995 | on the system. Note that a file which is larger than 8k blocks, it is | |
4996 | guaranteed to be non-contiguous. | |
4997 | ||
4998 | In mke2fs, print a warning message if a user tries to format a whole | |
4999 | disk (/dev/hda versus /dev/hda1). If a user really wants to format a | |
5000 | whole disk, the -F (force) option forces mke2fs to format a whole disk | |
5001 | as a filesytem. | |
5002 | ||
5003 | Fix a bug in fsck where in some cases it might start checking | |
5004 | partitions in the next pass before it finishes checking partitions in | |
5005 | the current pass. This still won't cause two partitions on the same | |
5006 | disk will be checked, so it's rarely a problem in real life. | |
5007 | ||
5008 | Patch lsattr so that it won't hang when checking a named pipe. | |
5009 | ||
5010 | Minor compilation fixes: | |
5011 | * Fix the order of libraries that were linked in debugfs. | |
5012 | * Allow the sources to be compiled with -ansi turned on. |
