3 | |
4 | SuSE's security team audited uuidd and came up with a few minor | |
5 | issues. None of them are serious given that uuidd runs setuid as a | |
6 | unprivileged user which has no special access other than libuuid | |
7 | directory, but it's good to get them fixed. | |
8 | ||
9 | One additional fix in ext2fs_swap_inode_full() needed for resize2fs to | |
10 | work correctly with in-inode extended attributes. | |
11 | ||
7affded7 TT |
12 | Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese |
13 | translations. | |
14 | ||
15 | Debugfs will avoid using a pager if the standard output is not a tty. | |
16 | ||
17 | Fix debugfs and tune2fs to correctly handle daylight savings time when | |
18 | parsing a time string. | |
19 | ||
20 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
21 | ||
22 | Fix fsck completion bars when multiple filesystems were being checked | |
23 | in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug: | |
24 | #203323, Addresses Sourceforge Bug: #1926023) | |
25 | ||
26 | Fix fsck so that progress information is sent back correctly when | |
27 | multiple filesystems are being check and the output of fsck is being | |
28 | redirected to a file descriptor. Also, include the device name (w/o | |
29 | spaces) in the progress information sent back via a file descriptor. | |
30 | (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug: | |
31 | #1926023) | |
32 | ||
33 | Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems. | |
34 | ||
35 | If logsave receives a SIGTERM or SIGINT signal, it will now pass that | |
36 | signal to its child process. | |
37 | ||
38 | Fix mke2fs's creation of are resize inode when there is a non-standard | |
39 | s_first_data_block setting. | |
40 | ||
41 | Fix bug in blkid when run by an unprivileged user; most devices were | |
42 | not reported correctly. 9Addresses Launchpad Bug: #220275) | |
43 | ||
44 | Mke2fs will not allow the logically incorect combination of | |
45 | resize_inode and meta_bg, which had previously caused mke2fs to create | |
46 | a corrupt fileystem. | |
47 | ||
48 | Fix fsck in German locales so that a 'j' means yes. | |
49 | (Addresses Sourceforge Bug: #1947683) | |

58 | Update valgrind options in test_script to work with valgrind 3.2.3 |
59 | ||
60 | Update texinfo.tex to a much newer version from the FSF. | |
61 | ||
62 | Remove bashism for configure script and from the lib/ss Makefile. | |
63 | Addresses Sourceforge Bug: 1921969 | |
64 | ||
65 | Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt. | |
66 | ||
67 | Fix build system so that if texinfo is not installed, it won't print a | |
68 | (harmless) error message. | |

71 | E2fsprogs 1.40.8 (March 13, 2008) |
72 | ================================= | |
73 | ||
74 | Fixed e2image -I so it works on image files which are larger than 2GB. | |
75 | ||
76 | Fixed e2fsck's handling of directory inodes with a corrupt size field. If | |
77 | the size is larger than the number of blocks found in the inode, don't | |
78 | try to allocate extra empty blocks at the end of the directory to make | |
79 | up the difference; there's no point to doing that. In addition, if | |
80 | the size is not a multiple of a blocksize, always fix it. | |
81 | ||
82 | E2fsck handled a pass 2 "should never happen error" by not giving | |
83 | enough information and then core dumping. Unfortunately, it was all | |
84 | too easy to trigger the "should never happen" situation if a | |
85 | directory's inode size was not correct. This has been fixed, but | |
86 | e2fsck has also been taught how to handle this situation more | |
87 | gracefully, by simply removing the inode hash tree information, so | |
88 | that it can be rebuilt again after e2fsck's pass 3. (Addresses | |
89 | Launchpad Bug: #129395) | |
90 | ||
91 | Resize2fs had a bug resizing large inodes with extended attributes | |
92 | that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed | |
93 | completely on big-endian systems such as PowerPC. The bug should be | |
94 | completely fixed now. Yay for regression test suites. (Addresses Red | |
95 | Hat Bugzilla: #434893) | |
96 | ||
97 | Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese | |
98 | translations. Many thanks to Philipp Thomas from Novell for stepping | |
99 | up to become the new German translation maintainer! (Addresses Debian | |
100 | Bugs: #302512, #370247, #401092, #412882). | |
101 | ||
102 | When e2fsck is clearing a corrupt inode's HTREE directory information, | |
103 | make it clear that it is just clearing the HTREE information, not the | |
104 | entire inode. | |
105 | ||
106 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
107 | ||
108 | Programmer's notes | |
109 | ------------------ | |
110 | ||
111 | Add new functions, ext2fs_dblist_get_last() and | |
112 | ext2fs_dblist_drop_last(), which allows the caller to examine the last | |
113 | directory block entry added to the list, and to drop if it necessary. | |
114 | ||
115 | Fixed a portability problem in libblkid with DJGPP. | |
116 | ||
117 | Fix an obvious typo in an "internal error" message in e2fsck. Thanks | |
118 | to Philipp Thomas for pointing this out. | |
119 | ||
120 | If the info files are not built, change "make install" so it doesn't | |
121 | fail with an error code. | |
122 | ||

124 | E2fsprogs 1.40.7 (February 28, 2008) |
125 | ==================================== | |
126 | ||
127 | Remove support for clearing the SPARSE_SUPER feature from tune2fs, and | |
128 | depreciate the -s option, since it can result in filesystems which | |
129 | e2fsck can't fix easily. There are very good reasons for wanting to | |
130 | disable sparse_super; users who wants to turn off sparse_super can use | |
131 | debugfs. (Addresses Sourceforge Bug: #1840286) | |
132 | ||
133 | Add missing options to mke2fs's usage message. (Addresses Sourceforge | |
134 | Bug: #1751393) | |
135 | ||
136 | Fix bug in resize2fs when large (greater than 128 byte) inodes are | |
137 | moved when a filesystem is shrunk; it was only moving the first 128 | |
138 | bytes, so extended attributes were not getting moved. (Addresses Red | |
139 | Hat Bugzilla: #434893) | |
140 | ||
141 | E2fsck now prints an explicit message when the bad block inode is | |
142 | updated, to avoid confusion about why the filesystem was modified. | |
143 | (Addresses Sourceforge Bug: #756460) | |
144 | ||
145 | Allow mke2fs and tune2fs manipulate the large_file feature. | |
146 | Previously we just let the kernel and e2fsck do this automatically, | |
147 | but e2fsck will no longer automatically clear the large_file feature. | |
148 | It still isn't really necessary to worry about this feature flag | |
149 | explicitly, but some users seem to care. (Addresses Red Hat Bugzilla: | |
150 | #258381) | |
151 | ||
152 | Suppress message about an old-style fstab if the fstab file is empty. | |
153 | (Addresses Debian Bug: #468176) | |
154 | ||
155 | Fix (really minor) bug in debugfs's find_free_block so it avoids | |
156 | reporting a free block more than once if there are too few free blocks | |
157 | in the filesystem. (Addresses Sourceforge Bug: #1096315) | |
158 | ||
159 | Change e2fsck to no longer clear the LARGE_FILES feature flag | |
160 | automatically, when there are no more > 2GB files in the filesystem. | |
161 | It's been almost a decade since there have been kernels that don't | |
162 | support this flag, and e2fsck clears it quietly without telling the | |
163 | user why the filesystem has been changed. | |
164 | ||
165 | Fix bug which could cause libblkid to seg fault if a device mapper | |
166 | volume disappears while it is being probed. (Addresses RedHat | |
167 | Bugzilla: #433857) | |
168 | ||
169 | Inhance e2fsck's reporting of unsupported filesystem feature flags. | |
170 | (Addresses Sourceforge Feature Request: #1175808) | |
171 | ||
172 | Fix option syntax in dumpe2fs for explicit superblock and blocksize | |
173 | parameters. What was currently documented in the man page has been | |
174 | broken for some time, due to getopt() implementation changes. The | |
175 | option sytax has been changed to one which is can be more portable | |
176 | supported and which is consistent with the format for extended options | |
177 | in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994) | |
178 | ||
179 | Add support to tune2fs to clear the resize_inode feature. This | |
180 | requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816) | |
181 | ||
182 | Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat | |
183 | Bugzilla: #409321) | |
184 | ||
185 | Add support for setting RAID stride and stripe-width via mke2fs and | |
186 | tune2fs. Teach dumpe2fs to print the RAID parameters. | |
187 | ||
188 | Add support for setting new superblock fields to debugfs's | |
189 | set_super_value. | |
190 | ||
191 | Add support for printing "mostly-printable" extended attributes in | |
192 | Debugfs. | |
193 | ||
194 | Add support for the -M option to fsck, which causes it to ignore | |
195 | mounted filesystem. | |
196 | ||
197 | Fix uuidd so that it creates the pid file with the correct pid number. | |
198 | (Addresses Sourceforge Bug: #1893244) | |
199 | ||
200 | Fix various gcc -Wall warnings. | |
201 | ||
202 | Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations | |
203 | ||
204 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
205 | (Addresses Sourceforge Patch: #1399325) | |

208 | Programmer's notes: | |
209 | ------------------- | |
210 | ||
211 | Fixed various Debian packaging issues --- see debian/changelog for | |
212 | details. (Addresses Debian Bug: #466929) | |
213 | ||
214 | Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a | |
215 | partially filled-in filesystem object on an error, so that e2fsck can | |
216 | print more intelligent error messages. | |
217 | ||
218 | Add a new function e2p_edit_feature2() which allows the caller to | |
219 | specify which feature flags are OK to set or clear, and which returns | |
220 | more specific information about feature flags which are not allowed to | |
221 | be set/cleared. | |
222 | ||
223 | Set the C locale in the test_script driver since it uses [A-Za-z]. | |
224 | (Addresses Sourceforge Bug: #1890526) | |
225 | ||
226 | Use fcntl locking instead of lockf in libuuid since Cygwin doesn't | |
227 | support lockf(). | |
228 | ||
229 | Change configure.in to avoid using the 'dc' command unless it is | |
230 | absolutely needed. (i.e., when using parsing a WIP-style version | |
231 | number) (Addresses Sourceforge Bug: #1893024) | |
232 | ||
233 | Add portability checks to support compilation under DJGPP. | |
234 | ||
235 | Update to the latest samba tdb code before the LGPLv3 change, which | |
236 | fixes a realloc() leak on failure. | |
237 | ||
238 | Fix memory leak in ext2fs_alloc_block(). | |
239 | ||
240 | Fix makefile dependency issues for various install targets. | |
241 | (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456) | |
242 | ||
243 | Improve descriptions for the r_move_itable and r_resize_inode tests. | |

e015f3d5 TT |
246 | E2fsprogs 1.40.6 (February 9, 2008) |
247 | =================================== | |
248 | ||
249 | Add support for returning labels for UDF filesystems in the blkid | |
250 | library. | |
251 | ||
252 | Fix bug in the blkid library where cached filesystems was not being | |
253 | flushed when opening USB devices returned the error ENOMEDIUM. | |
254 | (Addresses Debian Bug: #463787) | |
255 | ||
256 | Added logic to the blkid library to automatically choose whether a | |
257 | filesystem should be mounted as ext4 or ext4dev, as appropriate. | |
258 | ||
259 | Allow tune2fs to set and clear the test_fs flag on ext4 filesystems. | |
260 | ||
261 | Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been | |
262 | configured with --enable-jbd-debug. | |
263 | ||
264 | Document the BLKID_FILE environment variable in the libblkid man page | |
265 | ||
266 | Programmer's Notes: | |
267 | ------------------- | |
268 | ||
269 | Update e2fsprogs translation template and Vietnamese and Czech translations | |
270 | ||
271 | Fixed various Debian packaging issues --- see debian/changelog for | |
272 | details. (Addresses Debian Bugs: #436058) | |
273 | ||
274 | Don't try to create $DESTDIR/etc/init.d as part of make install as we | |
275 | don't install the init.d script (and it's not the recommended way to | |
276 | start uuidd anyway). (Addresses Sourceforge Bug: #1885085) | |
277 | ||
278 | Use thread local storage to fix a theoretical race condition if two | |
279 | threads try to format an unknown error code at the same time in the | |
280 | com_err library. | |
281 | ||
282 | ||
c8a5708d TT |
283 | E2fsprogs 1.40.5 (January 27, 2008) |
284 | =================================== | |
285 | ||
286 | Fix a potential overflow big in e2image if the device name is too | |
287 | long. | |
288 | ||
289 | Mke2fs will now create new filesystems with 256 byte inodes and the | |
290 | ext_attr feature flag by default. This allows for much better future | |
291 | compatibity with ext4 and speeds up extended attributes even on ext3 | |
292 | filesystems. | |
293 | ||
294 | Teach e2fsck to ignore certain "safe" filesystem features which are | |
295 | set automatically by the kernel. Having the kernel set features | |
296 | automagically behind the user's back is a bad idea, and we should try | |
297 | to break the kernel of this habit, especially for the newer ext4 | |
298 | feature flags. But for now, we will try to avoid needless full checks | |
299 | which can annoy users who are doing fresh installs. | |
300 | ||
301 | Add support in tune2fs and mke2fs for making a filesystem as being "ok | |
302 | to be used with test kernel code". This will be needed for using test | |
303 | filesystems with the latest ext4 kernel code. | |
304 | ||
305 | Change e2fsck -fD so that it sorts non-htree directories by inode | |
306 | numbers instead of by name, since that optimizes performances much | |
307 | more significantly. (Addresses-Sourceforge-Feature-Request: #532439) | |
308 | ||
309 | If e2image fills the disk, fix it so it exits right away instead of | |
310 | spewing large numbers of error messages. | |
311 | (Addresses-Sourceforge-Feature-Request: #606508) | |
312 | ||
313 | If ftruncate64() is not available for resize2fs, let it use ftrucate() | |
314 | instead, but have it check to see if the size would get truncated, and | |
315 | skip calling ftruncate in that case. | |
316 | ||
317 | Add support for detecting HFS+ filesystems in the blkid library. | |
318 | ||
319 | Add supprt in the blkid library for ext4/ext4dev filesystems. | |
320 | ||
321 | Fix a bug in blkid where it could die on a floating point exception | |
322 | when presented with a corrupt reiserfs image. | |
323 | ||
324 | Fix blkid's handling of ntfs UUID's so that leading zeros are printed | |
325 | such that UUID string is a fixed length. | |
326 | ||
327 | Add sample python bindings for the uuid library to the contrib | |
328 | directory. (Addresses-Sourceforge-Patches: #778817) | |
329 | ||
330 | Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it | |
331 | will work with large files. (Addresses Sourceforge Feature Request: | |
332 | #1257500 and Sourceforge Support Request: #1253511) | |
333 | ||
334 | Allow the debugfs 'undel' command to undelete an inode without linking | |
335 | it to a specific destination directory, since this might require | |
336 | allocating blocks that could overwrite some yet-to-be-recovered | |
337 | deleted files. (Addresses-Sourceforge-Feature-Request: #967141) | |
338 | ||
339 | Update Swedish translations from the Translation Project. | |
340 | ||
341 | Programmer's Notes: | |
342 | ------------------- | |
343 | ||
344 | Fix configure handling of --sbindir (which should rarely be used, but | |
345 | someone did complain, so let's fix it). (Addresses Sourceforge Bug: | |
346 | #498381) | |
347 | ||
348 | Updated e2fsprogs.spec file to include a new uuidd package | |
349 | ||
350 | Use pkg-config to determine where to find the devmapper library so we | |
351 | can find out where it is located on different distributions. | |
352 | ||
353 | Fix Makefile race so that "make -j3 distclean" works correctly | |
354 | ||
355 | Fix portability problems on non-Linux/non-Hurd/non-Masix systems, | |
356 | especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633, | |
357 | #1819034, #1863819) | |
358 | ||
359 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
360 | ||
361 | Fixed various Debian packaging issues --- see debian/changelog for | |
362 | details. (Addresses Debian Bugs: #459403, #459475, #459614) | |
363 | ||
364 | Remove the --enable-dynamic-static configure option, and build e2fsck | |
365 | dynamically by default. If the user wants e2fsck.static, he/she will | |
366 | need to build it via "make -C e2fsck e2fsck.static" | |
367 | ||
368 | Fix various build warnings due to missing prototypes. | |
369 | (Addresses Sourceforge Patch: #1861663, #1861659) | |

372 | E2fsprogs 1.40.4 (December 31, 2007) |
373 | ==================================== | |
374 | ||
375 | Improve time-based UUID generation. A new daemon uuidd, is started | |
376 | automatically by libuuid if necessary. This daemon is setuid to allow | |
377 | updates to /var/lib/libuuid, so the clock sequence number can be | |
378 | stored and so if the clock is set backwards, it can be detected. | |
379 | (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla: | |
380 | #233471) | |
381 | ||
382 | Filter out the NEEDS_RECOVERY feature flag when writing out the backup | |
383 | superblocks. This avoids e2fsck from concluding that a full | |
384 | filesystem check is required before backing up the superblock due to | |
385 | changes in the feature flags. (Addresses Debian Bug: #454926) | |
386 | ||
387 | Fix fsck to only treat the '#' character as a comment at the beginning | |
388 | of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem | |
389 | will cause fsck to issue an bogus warning message. | |
390 | (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147) | |
391 | ||
392 | Format control characters and characters with the high eighth bit set | |
393 | when printing the contents of the blkid cache, to prevent filesystems | |
394 | with garbage labels from sending escape sequences to the user's screen | |
395 | that might, for example place it in graphics mode. (Addresses Ubuntu | |
396 | Bug: #78087) | |
397 | ||
398 | Fix sign-extension problem on 64-bit systems in in the com_err | |
399 | library. (Addresses Sourceforge Bug: #1809658) | |
400 | ||
401 | Avoid division by zero error when probing an invalid FAT filesystem in | |
402 | the blkid library. (Addresses Sourceforge Bug: #1831627) | |
403 | ||
404 | Update Dutch, Polish, and Vietnamese translations from the Translation | |
405 | Project. Remove the Rwandan translation upon advice of the | |
406 | Translation Project. | |
407 | ||
408 | Programmer's Notes: | |
409 | ------------------- | |
410 | ||
411 | Fix the libss "make check" regression test so that it works if the | |
412 | current directory is not in the user's path or if the libss shared | |
413 | library is not installed. (Addresses Sourceforge Bug: #1848974) | |
414 | ||
415 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
416 | (Addresses Debian Bugs: #444883, #441872) | |
417 | ||

427 | E2fsprogs 1.40.3 (December 5, 2007) |
428 | =================================== | |
429 | ||
430 | Fix a potential security vulnerability where an untrusted filesystem | |
431 | can be corrupted in such a way that a program using libext2fs will | |
432 | allocate a buffer which is far too small. This can lead to either a | |
433 | crash or potentially a heap-based buffer overflow crash. No known | |
434 | exploits exist, but main concern is where an untrusted user who | |
435 | possesses privileged access in a guest Xen environment could corrupt a | |

441 | Fix hueristics in blkid which could cause a disk without partitions to | |
442 | be incorrectly skipped when a loopback device is present. (Addresses | |
443 | Red Hat Bugzilla #400321.) | |
444 | ||
445 | Fix e2image so that in raw mode it does not create an image file which | |
446 | is one byte too large. | |
447 | ||
448 | Change mke2fs's usage message so it recommends the preferred -E option | |
449 | instead of the deprecated -R option. | |
450 | ||
451 | Enhance the blkid library so it will recognize squashfs filesystems. | |
452 | (Addresses Red Hat Bugzilla #305151.) | |
453 | ||
454 | Enhance e2fsck so it will force the backup superblocks to be backed up | |
455 | if the filesystem is consistent and key constants have been changed | |
456 | (i.e., by an on-line resize) or by e2fsck in the course of its | |
457 | operations. | |
458 | ||
459 | Enhance blkid's detection of FAT filesystems; so that USB disks with | |
460 | only a single bootable partition will not get missed. | |
461 | ||
462 | E2fsck will no longer mark a filesystem as invalid if it has time | |
463 | errors (i.e., if superblock mount time or last write time is in the | |
464 | future) and the user refuses to fix the problem. | |
465 | ||
466 | The Ubuntu init scripts don't properly set the system time correctly | |
467 | from hardware clock if the hardware clock is configured to tick local | |
468 | time instead of GMT time. Work around this as best as we can by | |
469 | providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can | |
470 | be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu | |
471 | Bug #131201.) | |

473 | Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red | |
474 | Hat Bugzilla #151533.) | |
475 | ||
476 | Fix e2fsck so that if the superblock is corrupt, but still looks | |
477 | vaguely like an ext2/3/4 superblock, that it automatically tries to | |
478 | fall back to the backup superblock, instead of failing with a hard | |
479 | error. | |
480 | ||
481 | Make the e2fsprogs program more robust so that they will not crash | |
482 | when opening a corrupt filesystem where s_inode_size is zero. | |
483 | ||
484 | Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric | |
485 | arguments are detected as such and the parse error is reported to the | |
486 | user. (Addresses Debian Bug #435381.) | |
487 | ||
488 | Change e2fsck so it will not complain if a file has blocks reallocated | |
489 | up to the next multiple of a system's page size. | |
490 | ||
491 | Fix bug in ext2fs_check_desc() which will cause e2fsck to complain | |
492 | about (valid) filesystems where the inode table extends to the last | |
493 | block of the block group. (Addresses Red Hat Bugzilla #214765.) | |
494 | ||
495 | Fix a bug in ext2fs_initialize() which causes mke2fs to fail while | |
496 | allocating inode tables for some relatively rare odd disk sizes. | |

510 | Programmer's Notes: | |
511 | ------------------- | |
512 | ||
513 | Fix mke2fs tests to avoid needing any significant ^M (CR) characters | |
514 | ||
515 | Add "make check" to the RPM spec file | |
516 | ||
517 | Fix "make install" and 'make unstall" in misc/Makefile.in so that it | |
518 | works correctly when the prefix is not the root directory. | |
519 | ||
520 | Fix the resize2fs tests, r_move_itable and r_resize_inode, so they | |
521 | clena up after themselves by deleting the test.img temporary file | |
522 | after completing the test. | |
523 | ||
524 | Fixed a corner case bug ext2fs_unlink() when trying to delete the | |
525 | first directory entry in a directory block and the last directory | |
526 | entry in the previous directory block is not in use. Fortunately | |
527 | ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in | |
528 | places where it is extremely unlikely to run into this corner case. | |
529 | ||
530 | Fix missing dependency which would cuase parallel builds to fail. | |
531 | (Addresses Sourceforge Bug #1842331.) | |
532 | ||
533 | Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c | |
534 | calling open(O_CREATE) with a missing mode parameter. | |
535 | ||
536 | Fix the test_ss.c in lib/ss so it can be used as an example | |
537 | application program for the library as well as a regression test | |
538 | suite. | |
539 | ||
540 | Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes | |
541 | are properly passed back up through the call stack. | |

543 | E2fsprogs 1.40.2 (July 12, 2007) |
544 | ================================ | |
545 | ||
546 | A recent change to e2fsck_add_dir_info() to use tdb files to check | |
547 | filesystems with a very large number of filesystems had a typo which | |
548 | caused us to resize the wrong data structure. This would cause a | |
549 | array overrun leading to malloc pointer corruptions and segfaults. | |
550 | Since we normally can very accurately predict how big the the dirinfo | |
551 | array needs to be, this bug only got triggered on very badly corrupted | |
552 | filesystems. | |
553 | ||
554 | Fix a bug in e2fsck which caused it to incorrectly salvange | |
555 | directories when the last entry's rec_len is bogusly too big. This | |
556 | resulted in a nonsense filesystem corruption to be reported, and | |
557 | required a second run of e2fsck to fully fix up the directory. | |

569 | Fix bug which could cause libblkid to loop forever. When revalidating | |
570 | a partition where there is obsolete information in /etc/blkid.tab, we | |
571 | end up freeing a the type tag without clearing dev->bid_type, causing | |
572 | blkid_verify() to loop forever. (Addresses Debian Bug: #432052) | |
573 | ||
574 | The Turkish translation has a bug in it where it has the translation | |
575 | of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at | |
576 | @E, recursively, forever, until the stack fills up and e2fsck core | |
577 | dumps. We fix this by making e2fsck stop @-expansions after a | |
578 | recursive depth of 10, which is far more than we need. | |

582 | getting surprised by mke2fs creating filesystems with different | |
583 | defaults than earlier versions of mke2fs if mke2fs.conf is not | |
584 | present. So we now create a built in version of mke2fs.conf file | |
585 | which is used by mke2fs if the /etc/mke2fs.conf is not present. | |
586 | (Addresses SourceforgeBug: #1745818) | |
587 | ||
588 | Improve the config/parse_types.sh helper script. Fix a potential | |
589 | security problem if e2fsprogs is built as root (as Gentoo does!). In | |
590 | addition fix the script and how it is called from the configure script | |
591 | so that it does the right thing when cross-compiling. (Fixes Gentoo | |
592 | bug: #146903) | |
593 | ||
594 | Update Vietnamese, French, and Dutch PO files from the Translation | |
595 | Project. Also created a new e2fsprogs.pot file for translator. | |
596 | ||
597 | Fix bogus strip permission errors when building under Debian. When | |
598 | building the e2fsprogs dpkg's, the dh_strip command emits a large | |
599 | number of error messages caused by the permissions not being right. | |
600 | So run dh_fixperms before running dh_strip. | |

602 | Programmer's Notes: | |
603 | ------------------- | |
604 | ||
605 | Add new function: profile_set_default(). This function sets the value | |
606 | of the pseudo file "<default>". If the file "<default>" had | |
607 | previously been passed to profile_init(), then def_string parameter | |
608 | will be parsed and used as the profile information for the "<default>" | |
609 | file. | |
610 | ||
611 | Fix mk_cmds's error reporting so that it is unambiguous that it is the | |
612 | mk_cmds script which is generating the error. (Obviates Gentoo patch: | |
613 | e2fsprogs-1.32-mk_cmds-cosmetic.patch) | |
614 | ||
615 | Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high | |
616 | priority" environment variable that overrides all others, where as | |
617 | LANG is the lowest priorty environment variable. If LC_ALL is set, it | |
618 | doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and | |
619 | the all the rest are set. This will assure that the locale when | |
620 | running the test suites is the "C" locale. (Obviates Gentoo patch: | |

628 | |
629 | Add new blkid -g option which causes the blkid cache to be garbage | |
630 | collected. | |
631 | ||
632 | Fix a bug in libblkid which could cause the internal field bid_type to | |
633 | become corrupted. Fortunately bid_type isn't used much, and bid_label | |
634 | and bid_uuid is only used by debugging code, so the impact of this bug | |
635 | was very minor. | |
636 | ||
637 | Mke2fs will now store the RAID stride value when a filesystem is | |
638 | created with a requested RAID stride, and then use it automatically in | |
639 | resize2fs. | |
640 | ||
641 | Mke2fs has a sanity check added to make sure (inode_size * num_inodes) | |
642 | isn't too big. In some cases Lustre users have tried specifying an | |
643 | inode size of 4096 bytes, while keeping an inode ratio of one inode | |
644 | per 4096 bytes. | |
645 | ||
646 | Improve sanity check in e2fsck's algorithm for finding a backup | |
647 | superblock, so that it won't accidentally find a superblock that was | |
648 | located in the journal, and then later reject it as being not a valid | |
649 | backup superblock. | |
650 | ||
651 | Fix e2fsck get_size logic so that it will work with the Linux floppy | |
652 | driver. The Linux floppy driver is a bit different from the other | |
653 | block device drivers, in that if the device has been opened with | |
654 | O_EXCL, it disallows another open(), even if the second open() does | |
655 | not have the O_EXCL flag. (Addresses Debian Bug: #410569) | |
656 | ||
657 | Fix error checking of badblock's last-block and start-block arguments. | |
658 | (Addresses Debian Bug: #416477) | |
659 | ||
660 | Fix e2fsck so that it doesn't overwrite the backup superblocks when | |
661 | recovering a journal until the master superblock has been confirmed as | |
662 | being sane. | |
663 | ||
664 | Change the blkid library to be much more paranoid about concluding | |
665 | that a partition contains an NTFS filesystem, and fetch the UUID and | |
666 | LABEL information from NTFS filesystems. (Addresses Launchpad Bug: | |
667 | #110138) | |
668 | ||
669 | Factor out the code which sets the default journal size and move it | |
670 | into libext2fs. | |
671 | ||
672 | Enhance e2fsck so it will recreate the ext3 journal if the original | |
673 | journal inode was cleared to due it being corrupt after finishing the | |
674 | filesystem check. | |
675 | ||
676 | Fix e2fsck so that it updates the journal inode if it is corrupted and | |
677 | the backup journal information from the superblock was successfully | |
678 | used to recover the filesystem. | |
679 | ||
680 | Fix e2fsck so that it checks all of the blocks in the journal inode | |
681 | for validity. The original code only checked the direct blocks to | |
682 | make sure the journal inode was sane. Unfortunately, if some or all | |
683 | of the indirect or doubly indirect blocks were corrupted, this would | |
684 | not be caught. | |
685 | ||
686 | Add support in blkid to detect LUKS encrypted partitions. | |
687 | ||
688 | Add extra sanity checks for extended attributes in the case where the | |
689 | size is zero but the offset is very large. | |
690 | ||

692 | and ext2fs_get_next_inode_full(). | |

694 | Clarify the copyright licenses used by the various libraries in | |
695 | the top-level COPYING file (Red Hat Bugzilla: 166058) | |
696 | ||
697 | Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane. | |
698 | ||
699 | Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's. | |
700 | ||
701 | Remove check in e2fsck which requires EA's in inodes to be sorted; | |
702 | they don't need to be sorted, and e2fsck was previously wrongly | |
703 | clearing unsorted EA's stored in the inode structure. | |
704 | ||
705 | Allow mke2fs or tune2fs to create a substantially larger journal (up | |
706 | to 10,240,000 blocks). | |
707 | ||
708 | Fix MD superblock detection, and make sure the correct UUID is | |
709 | reported from the MD superblock. | |
710 | ||
711 | Fix a signed vs. unsigned bug in debugfs. | |
712 | ||
713 | Enhance debugfs's date parser so that it accepts integer values. | |
714 | ||
715 | Fix e2fsck's pass1c accounting so it doesn't terminate too early if a | |
716 | file with multiply claimed blocks is hard linked. or not at all if the | |
717 | root directory contains shared blocks | |
718 | ||
719 | Enhance debugfs so it can modify the block group descriptors using the | |
720 | command set_block_group_descriptor. | |

748 | ||
749 | Enhance e2fsck to recover directories whose modes field were corrupted | |
750 | to look like special files. This is probably only useful in | |
751 | artificial test cases, but it will be useful if we ever do the "inodes | |
752 | in directory" idea for ext4. | |

754 | Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug: | |
755 | #412614) | |
756 | ||
757 | Fix resize2fs parsing of size parameter (in sector units). This was | |
758 | actually a bug in libe2p's parse_num_blocks() function. When handling | |
759 | the 's' suffix, it was ignoring the blocksize information passed in | |
760 | from the caller and always interpreting the number in terms of a 1k | |

861 | e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107) | |
862 | ||
863 | Fix the info-dir line so that the menu name does not contain a .info | |
864 | prefix. First of all, it's ugly, secondly, it causes the install-info | |
865 | command to fail to remove the com_err info file from the | |
866 | /usr/share/info/dir file when the comerr-dev package is removed and | |
867 | purged. (Addresses Debian Bug: #401711) | |
868 | ||
26bcc2ca | 869 | Fixed spelling mistakes, typos, and otherwise clarified man pages. |

877 | Programmer's notes: | |
878 | ------------------- | |
879 | ||
a0d42548 TT |
880 | E2fsck now supports the %It expansion when printing a problem report. |
881 | It will print the type of the inode in the problem context. | |
882 | ||
26bcc2ca TT |
883 | Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet |
884 | (Addresses Sourceforge Bug: #1565561) | |
885 | ||
886 | Remove unused variables and other lint/gcc -Wall cleanups | |
887 | ||
888 | Add check to ext2fs_get_device_size() so it will return EFBIG for for | |
889 | filesystems contained in regular files where the filesystem image size | |
890 | is returned by stat64(). | |
891 | ||
7809bc56 TT |
892 | Set local environment variables to C so mk_cmds and compile_et always |
893 | work. (Addresses SourceForge Bug: #1532177) | |
894 | ||
26bcc2ca TT |
895 | Added the 64-bit byte swapping function ext2fs_swab64(). |
896 | ||
897 | Added two new helper functions to prevent 2**31/2**32-1 overflow | |
898 | problems: ext2fs_div_ceil() and e2p_percent(). | |
899 | ||
900 | Create new ext2fs library inline functions ext2fs_group_first_block() | |
901 | and ext2fs_group_last_block() in order to calculate the starting and | |
902 | ending blocks in a block group. | |
903 | ||
904 | Create the generated files read-only to remind developers not to edit them. | |
905 | ||
7809bc56 TT |
906 | Add support for autoconf 2.60 (with backwards compatibility for older |
907 | versions of autoconf). | |
908 | ||
26bcc2ca TT |
909 | Added an "make rpm" target to top-level Makefile |
910 | ||
911 | Added various FreeBSD portability fixes. | |
912 | ||
913 | Exclude mercurial files from the RPM build tree to speed up copy/build. | |
914 | ||
915 | Use root_sysconfdir to define the locations of mke2fs.conf and | |
916 | e2fsck.conf instead of using a hard-coded /etc pathname. | |
917 | ||
918 | Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times. | |
919 | ||
920 | Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files. | |
921 | ||
922 | If diff -u is supported, use it to report test failures. | |
923 | ||
924 | Updates/improvements to RPM spec file | |
925 | ||
7809bc56 TT |
926 | Add on-disk format definitions for the following new features: |
927 | EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM, | |
928 | EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT, | |
929 | EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE | |
930 | ||
931 | Add a new make target "checked-failed" in the tests directory which | |
932 | reruns any failed tests | |
933 | ||
934 | Update draft-leach-uuids-guids-01.txt with rfc4122.txt | |
935 | ||
a0d42548 TT |
936 | Fix miscellaneous bugs reported by Coverity: Dead code, potential nul |
937 | pointer dereferences, memory leaks, etc. None were security-criticial | |
938 | problems. | |
939 | ||
940 | Fix up usage and decrement error messages in the test_icount program | |
941 | ||
942 | Add debugging code to the com_err library; if the environment variable | |
943 | COMERR_DEBUG is set to 1, print out debugging messages as error tables | |
944 | are added and removed from the com_err library. If the | |
945 | COMERR_DEBUG_FILE environment variable is set (and the process is not | |
946 | setuid) the debugging messages may be redirected to a file. | |
947 | ||
948 | Change all of the e2fsprogs programs to use the newer add_error_table() | |
949 | and remove_error_table() interfaces instead of the much older | |
950 | initialize_*_error_table() function. | |
951 | ||
952 | Add TDB support into the ext2fs library. This allows us to have a | |
953 | guaranteed library we can count on always being present so we can | |
954 | store data in an on-disk database. | |
955 | ||
956 | Add support for using TDB to store the icount data, so we don't run out | |
957 | of memory when checking really large filesystems. | |
958 | ||
d7b64725 TT |
959 | Change the regression test suite so that it skips empty test directories. |
960 | ||
961 | Define the l_i_iversion field in ext2_inode. The l_i_version field is | |
962 | now defined from the old l_i_reserved1 field in the ext2 inode. This | |
963 | field will be used to store high 32 bits of the 64-bit inode version | |
964 | number. | |
965 | ||
966 | Add Makefile production rule for e2fsprogs.spec in case it gets | |
967 | deleted. | |
968 | ||
969 | Add new function profile_get_uint() to allow for a clean way to fetch | |
970 | unsigned integers from the context. | |
971 | ||
972 | Add test to make sure the ext2 superblock structure is 1024 bytes. | |
973 | ||
974 | Fix typo in name of f_dup4 regression test | |
975 | ||
976 | Add new function blkid_gc_cache() which performs a garbage collection | |
977 | pass on the /etc/blkid.tab file. | |
978 | ||
979 | The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In | |
980 | general, only e2fsck (after the filesystem is clean), tune2fs, and | |
981 | resize2fs should change the backup superblocks by default. Most | |
982 | callers of ext2fs_open() should not be touching any superblock fields | |
983 | which require the backups to be touched. | |
984 | ||
985 | Add new function to libext2fs, ext2fs_default_journal_size(), which | |
986 | returns the default journal size. | |
987 | ||
26bcc2ca | 988 | |
6c09475b TT |
989 | E2fsprogs 1.39 (May 29, 2006) |
990 | ============================= | |
34a2611c | 991 | |
34a2611c TT |
992 | Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems |
993 | between 2**31 and 2**32 blocks. | |
994 | ||
34a2611c TT |
995 | Change mke2fs to use /etc/mke2fs.conf as a configuration file to |
996 | configure the filesystem features, blocksize, and inode_ratio for | |
997 | different filesystem types. | |
998 | ||
6c09475b TT |
999 | Mke2fs will now create filesystems hash trees and on-line resizing |
1000 | enabled by default, based on the new /etc/mke2fs.conf file. | |
1001 | ||
34a2611c TT |
1002 | The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the |
1003 | filesystem device node in exclusive mode to prevent accidents by | |
1004 | system administrators. In the case of resize2fs and mke2fs, it will | |
1005 | only use exclusive mode if the filesystem is not mounted. | |
1006 | ||
1007 | Fixed a bug in mke2fs which caused it to to fail when creating the | |
1008 | resize inode for large filesystems. (Addresses Debian Bug #346580) | |
1009 | ||
bae55640 TT |
1010 | When allocating space for the RAID filesystems with the stride |
1011 | parameter, mke2fs will now place each portion of the group's inode | |
1012 | table right up after the superblock (if present) in order to minimize | |
1013 | fragmentation of the freespace. | |
1014 | ||
1015 | Speed up mke2fs and e2fsck by writing inode and block bitmaps more | |
1016 | efficiently by writing the inode and block bitmaps in one pass, thus | |
1017 | reducing the number of disk seeks required. | |
1018 | ||
34a2611c TT |
1019 | Add support for on-line resizing to resize2fs. |
1020 | ||
1021 | Fix blkid library so that logic to determine whether or not a device's | |
1022 | cached information in /etc/blkid.tab needs to be verified or not | |
1023 | doesn't get confused by a system clock which is insane (for example, | |
1024 | if the battery is dead on a Macintosh running PPC Linux. (Addresses | |
1025 | Red Hat Bug: #182188) | |
1026 | ||
1027 | The blkid library will now store the UUID of the external journal used | |
1028 | by ext3 filesystems, so that in the future, the userspace mount binary | |
1029 | can use this to find the location of the external journal and pass | |
1030 | this information to the kernel. | |
f3227850 TT |
1031 | |
1032 | E2fsck will now consult a configuration file, /etc/e2fsck.conf to | |
34a2611c TT |
1033 | control how various options should be handled. See the e2fsck.conf |
1034 | man page for more details. (Addresses Debian Bug: #150295) | |
f3227850 | 1035 | |
34a2611c TT |
1036 | E2fsck now prints an explanatory message when delaying a filesystem |
1037 | check when the system is running on battery. (Addresses Debian Bug: | |
1038 | #350306) | |
f2b74cda | 1039 | |
4c02c41c TT |
1040 | E2fsck will detect if the superblock's last mount field or last write |
1041 | field is in the future, and offer to fix if so. (Addresses Debian Bug | |
f3227850 TT |
1042 | #327580) These problems will be fixed automatically in preen mode |
1043 | since Debian's boot sequence bogusly doesn't set the time correctly | |
1044 | until potentially very late in the bootup process, and this can cause | |
1045 | false positives which will cause users' systems to fail to boot. | |
1046 | (Addresses Debian Bugs #343662 and #343645) | |
f2b74cda | 1047 | |
34a2611c TT |
1048 | E2fsck now checks to see if the superblock hint for the location of |
1049 | the external journal is incorrect, and if so, offer to update it. | |
1050 | (Addresses Debian Bug: #355644) | |
1051 | ||
f2b74cda TT |
1052 | Fix e2fsck from segfaulting on disconnected inodes that contain one or |
1053 | more extended attributes. (Addresses Debian Bug: #316736, #318463) | |
1054 | ||
4c02c41c TT |
1055 | E2fsck will stop and print a warning if the user tries running a |
1056 | read/write badblocks test on a read-only mounted root filesystem. | |
1057 | ||
bae55640 TT |
1058 | Fix a memory leak in e2fsck's error paths. (Thanks to Michael |
1059 | C. Thompson for pointing these out; they were originally found using | |
1060 | Coverity.) | |
1061 | ||
f3227850 TT |
1062 | When resizing a file containing a filesystem, resize2fs will expand or |
1063 | truncate a file as necessary. (Addresses Debian Bug: #271607) | |
1064 | ||
bae55640 TT |
1065 | Resize2fs will now automatically determine the RAID stride parameter that |
1066 | had been used to create the filesystem, and use that for newly created | |
1067 | block groups. The RAID stride parameter may also be manually specified | |
1068 | on the command line using the new -S option to resize2fs. | |
1069 | ||
4c02c41c TT |
1070 | Fix mke2fs so that it correctly creates external journals on |
1071 | big-endian machines (such as a S/390). | |
1072 | ||
bae55640 TT |
1073 | Fix a bug in the e2p library which could cause dumpe2fs to (rarely) |
1074 | fail to print out the journal or hash seed UUID. (Thanks to Guillaume | |
1075 | Chambraud for pointing this out.) | |
1076 | ||
1077 | Dumpe2fs will now print the size of the journal (if present). | |
1078 | ||
4c02c41c TT |
1079 | Fix debugfs's set_inode_field command so it can properly set the frag, |
1080 | fsize, uid_high, gid_high, and author fields in the inode instead of | |
1081 | silently failing, and so that setting the i_size actually sets i_size | |
1082 | correctly. | |
1083 | ||
1084 | Add a new debugfs command, set_current_time, which sets fs->now so | |
1085 | that regression test suites can repeatedly modify the filesystem's | |
1086 | last_write fields. | |
1087 | ||
34a2611c TT |
1088 | Fix a bug in debugfs's icheck which would incorrectly report the owner |
1089 | of an extended attribute block. | |
1090 | ||
bae55640 TT |
1091 | Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a |
1092 | print a usage message when an illegal option character is given. | |
1093 | ||
6c09475b TT |
1094 | Fix debugfs's dump_unsued command on filesystems with a 64k blocksize |
1095 | so it won't core dump. (Addresses SourceForge bug #1424311) | |
1096 | ||
bae55640 TT |
1097 | Fix mklost+found so that it creates a full-sized directory on |
1098 | filesystems with larger block sizes. | |
1099 | ||
1100 | Fix a file descriptor leak in blkid library. | |
1101 | ||
4c02c41c TT |
1102 | Fix a display bug in "badblocks -sv" so that the done message properly |
1103 | clears the block number at the end of the test. (Addresses Debian Bug | |
1104 | #322231) | |
1105 | ||
f2b74cda TT |
1106 | Allow fractional percentages to the -m option in mke2fs and tune2fs |
1107 | (Addresses Debian Bug: #80205) | |
1108 | ||
1109 | Use fstat/fstat64 in getsize.c if the the target is a regular file, | |
1110 | instead of attempting to do a binary search. Fix some fd leaks in | |
1111 | error cases. | |
1112 | ||
34a2611c TT |
1113 | Add support for device mapper library to the blkid library to ensure |
1114 | that the "best" (i.e., leaf) device is probed by the blkid library. | |
1115 | ||
4c02c41c TT |
1116 | Fix the blkid library so that it notices when an ext2 filesystem is |
1117 | upgraded to ext3. | |
1118 | ||
1119 | Improve the blkid's library VFAT/FAT detection; it now understands | |
1120 | labels stored in the root directory, and is more paranoid about | |
1121 | checking the FAT superblock values. | |
1122 | ||
34a2611c TT |
1123 | Fixed a fd leak in the uuid library which was causing problems for the |
1124 | LVM tools. (Addresses Debian Bug: #345832) | |
1125 | ||
4c02c41c TT |
1126 | Add support for the reiser4 and software suspend partitions to the |
1127 | blkid library. Also add support for extract the label from iso9660 | |
1128 | filesystems. | |
1129 | ||
f2b74cda TT |
1130 | Fix a compile_et bug which miscount the number of error messages if |
1131 | continuations are used in the .et file. | |
1132 | ||
1133 | Add extra sanity checks to protect users from unusual cirucmstances | |
1134 | where /etc/mtab may not be sane, by checking to see if the device is | |
1135 | reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug | |
1136 | #319002) | |
1137 | ||
34a2611c TT |
1138 | Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian |
1139 | Bug: #343149, #341911, #300871, #316604, #316782, #330789) | |
4c02c41c | 1140 | |
f2b74cda TT |
1141 | Fix use-after-free bug in e2fsck when finishing up the use of the |
1142 | e2fsck context structure. | |
1143 | ||
34a2611c TT |
1144 | Fixed spelling mistakes, typos, and otherwise clarified man pages and |
1145 | documentation. (Addresses Debian Bugs: #329859, #322188, #316811, | |

1155 | Programmer's notes: | |
1156 | ------------------- | |
1157 | ||
7e2ec011 TT |
1158 | Update config.guess and config.sub to latest version (2006-02-23) from |
1159 | FSF. | |
1160 | ||
1161 | Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian | |
1162 | Bugs: #360661, #360317) | |
1163 | ||
34a2611c TT |
1164 | Fixed the Makefile so that they work correctly on newer versions of |
1165 | GNU make (i.e., 3.81). | |
1166 | ||
f2b74cda TT |
1167 | Add valgrind support to the regression test suites, and eliminate |
1168 | false positives from valgrind. | |
1169 | ||
4c02c41c TT |
1170 | Add a regression test suite for the blkid library. |
1171 | ||
f2b74cda TT |
1172 | Fix a fencepost error in resize2fs caught by valgrind. |
1173 | ||
4c02c41c TT |
1174 | Fix compiler warnings about missing memcpy prototypes. |
1175 | ||
1176 | We no longer have the sparc assembly code in the header file any more, | |
1177 | so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would | |
1178 | break compiles on the sparc architectures when using gcc. | |
1179 | ||
1180 | In the libext2fs library, add the new field fs->now which if non-zero | |
1181 | is used instead of the system time when setting various filesystem | |
1182 | fields (last modified time, last write time, etc.) | |
1183 | ||
1184 | Fix gcc 4.01 complaints by adding a missing #include <string.h> to | |
1185 | ext2fs.h which is needed since the inline functions use memcpy(). | |
1186 | (Addresses Sourceforge Bug #1251062) | |
1187 | ||
1188 | Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in | |
1189 | the build system when building files in the util directory which are | |
1190 | needed during the build process. This avoids potential problems when | |
1191 | cross-compiling and some of the options specified in CFLAGS or LDFLAGS | |
1192 | are not recognized as valid by the host compiler. (Addresses | |
1193 | Sourceforge Bug #1261547) | |
1194 | ||
1195 | Clean up the blkid library by making the superblock and generic i/o | |
1196 | functions to be more generic. Clean up interface to the probe | |
1197 | function, and fix memory leak. Finallly, remove an unneeded reference | |
1198 | to probe.h in the lib/blkid/resolve.c | |
1199 | ||
3285a9c9 TT |
1200 | Add an ext2fs_read_bb_FILE regression test to confirm proper detection |
1201 | of invalid block #'s. | |
1202 | ||
34a2611c TT |
1203 | The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to |
1204 | indicate that the the function read/writes the memory location. | |
1205 | ||
3285a9c9 TT |
1206 | Fix various gcc -Wall complaints. |
1207 | ||
1208 | Add a dependency to make sure that the subdirectories are created | |
1209 | before creating all of the object files, in order to address parallel | |
1210 | build problem in the library Makefiles. (Addresses Sourceforge Bug: | |
1211 | #1261553) | |
1212 | ||
1213 | Add $(LDFLAGS) to the command line argument when generating an ELF or | |
1214 | Solaris shared library, to allow cross-compile and other builds that | |
1215 | might need to specify -L paths to needed libraries. (Addresses | |
1216 | Sourceforge Bug #1261549) | |
1217 | ||
bae55640 TT |
1218 | Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially |
1219 | intended for testing purposes. It allows an ext2/ext3 developer to | |
1220 | create very large filesystems using sparse files where most of the | |
1221 | block groups are not initialized and so do not require much disk | |
1222 | space. Eventually it could be used as a way of speeding up mke2fs and | |
1223 | e2fsck for large filesystem, but that would be best done by adding an | |
1224 | RO_COMPAT extension to the filesystem to allow the inode table to be | |
1225 | lazily initialized on a per-block basis, instead of being entirely | |
1226 | initialized or entirely unused on a per-blockgroup basis. | |
1227 | ||
6c09475b TT |
1228 | Fix backwards compatibility so e2fsprogs will better compile on Linux |

fea95ffc | 1238 | E2fsprogs 1.38 (June 30, 2005) |
1f965c8d TT |
1239 | ============================== |
1240 | ||
1241 | Fix blkid's test programs (built with "make check") compile correctly | |
1242 | even without "configure --enable-blkid-debug". | |
1243 | ||
1244 | Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict | |
1245 | type aliasing rules on newer gcc compilers. (Addresses Red Hat | |
1246 | Bugzilla ##161183.) | |
1247 | ||
1248 | Fix com_err library to make it more compatible with recent changes | |
1249 | made to the com_err library in MIT Kerberos V5 version 1.4. | |
1250 | (Addresses Sourcefroge Bug #1150146) | |
1251 | ||
1252 | General cleanup of messages printed by e2fsprogs programs for grammar, | |
1253 | consistency, and to make life easier for translators. Fixed a few | |
1254 | strings containing English that had not been marked as needing | |
1255 | translations. Removed strings that do not need to be translated, to | |
1256 | make life easier for translators. | |
1257 | ||
1258 | Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to | |
1259 | test to see if a device appears to be in use instead of just relying | |
1260 | on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594). | |
1261 | ||
1262 | Fix portability problem in the filefrag program affecting platforms | |
1263 | where the size of an integer is smaller than the size of a long. | |
1264 | (Addresses Debian Bug #309655) | |
1265 | ||
1266 | Mke2fs will now use a larger journal by default for filesystems | |
1267 | greater than 4GB. (128 MB instead of 32MB). | |
1268 | ||
1269 | Mke2fs will refuse to create filesystems greater than 2**31-1 blocks, | |
1270 | unless forced. This is to avoid signed vs. unsigned kernel bugs in | |
1271 | block numbers that still need to be fixed. | |
1272 | ||
1273 | The blkid program has a new option which will more efficiently search | |
1274 | for device when it is known (or expected) that only one matching | |
1275 | device will be found in the system, such as when doing a lookup by | |
1276 | UUID. | |
1277 | ||
1278 | Debian's e2fsprogs-specific initrd fragment will avoid including | |
1279 | unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD | |
1280 | and LD_LIBRARY_PATH, and filtering out libraries found in | |
1281 | /etc/ld.so.preload. (Addresses Debian Bug: #304003) | |
1282 | ||
1283 | Fixed a potential portability issue in the blkid programs for | |
1284 | architectures where the char type is unsigned. (Addresses Sourceforge | |
1285 | Bug: #1180585) | |
1286 | ||
1287 | Fix a bug in filefrag so that it doesn't falsely count an extra | |
1288 | discontinuity when the first block found is an indirect block. | |
1289 | (Addresses Debian Bug #307607). | |
1290 | ||
1291 | Fix blkid's recognition of cramfs filesystems, and enhance it to be | |
1292 | able to handle cramfs labels. | |
1293 | ||
1294 | Fix debugfs's stat command to not core dump when a filesystem is not | |
1295 | open. | |
1296 | ||
1297 | Fix e2fsck's handling of error conditions caused by the resize inode | |
1298 | claiming blocks that are also used by other inodes, a filesystem | |
1299 | corruption which was commonly caused by a bug in Fedora Core 3's | |
1300 | resize2fs program. | |
1301 | ||
1302 | Fixed bug in filefrag which caused it to fail on non-ext2/3 | |
1303 | filesystems. (Addresses Debian Bug: #303509) | |
1304 | ||
1305 | If the superblock last mount time indicates that the system clock may | |
1306 | not be accurate, then e2fsck will omit checking inodes' deletion time | |
1307 | field for indications of a potential corrupted orphaned inode list. | |
1308 | (Previously e2fsck only ommited these LOW_DTIME checks when the | |
1309 | superblock's last write time looked insane.) | |
1310 | ||
1311 | Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs. | |
1312 | (Addresses Debian bug #302200) | |
1313 | ||
1314 | Make the blkid library more paranoid about being run from setgid | |
1315 | programs, and to use __secure_getenv() from libc if it is available. | |
1316 | ||
1317 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
1318 | (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593 | |
1319 | and Sourceforge Bug: #1189803) | |
1320 | ||
1321 | Updated and fixed translations. | |
1322 | ||
1323 | Fixed various Debian packaging issues --- see debian/changelog for | |
1324 | details. | |
1325 | ||
1326 | Programmer's notes: | |
1327 | ------------------- | |
1328 | ||
1329 | Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been | |
1330 | changed to take an unsigned int for the bit number. Negative bit | |
1331 | numbers were never allowed (and didn't make any sense), so this should | |
1332 | be a safe change. This is needed to allow safe use of block numbers | |
1333 | greater than or equal to 2**31. | |
1334 | ||
1335 | The compile_et program will avoid recreating generated foo_err.c and | |
1336 | foo_err.h files if no changes are necessary. The compile_et program | |
1337 | will also atomically replace these files to avoid a potential parallel | |
1338 | build race problem on SMP systems. (Addresses Sourceforge Bug: | |
1339 | #1157933) | |
1340 | ||
1341 | Added a new function to the blkid library, blkid_probe_all_new(), | |
1342 | which only probes newly added disk devices, and change | |
1343 | blkid_find_dev_with_tag() to use this function so that when a | |
1344 | requested tag is not found, devices that were previously not checked | |
1345 | are searched before searching all devices in the system. | |
1346 | ||
1347 | Added new functions to the blkid library, blkid_dev_set_search() and | |
1348 | blkid_dev_has_tag(). | |
1349 | ||
1350 | E2fsck's problem strings can now use @m and @n as abbrevations for | |
1351 | "multiply-claimed" and "invalid", respectively. | |
1352 | ||
1353 | The e2fsprog.pot file now has an explanation of how the @-expansion | |
1354 | and %-expansion works, and strings in e2fsck/problem.c which contain @ | |
1355 | characters now have comments in e2fsprogs.pot with the @-expansion to | |
1356 | make life easier for translators. | |
1357 | ||
1358 | Fixed missing return values in the ext2fs library which could cause it | |
1359 | to return random garbage in certain error conditions. | |
1360 | ||
1361 | Allow the current time to be overriden via the E2FSCK_TIME environment | |
1362 | variable for use in regression tests. | |
1363 | ||
1364 | The test scrpit driver program now exits with a non-zero status if | |
1365 | there any of its test that it ran failed. | |
1366 | ||
1367 | Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge | |
1368 | Bug: #1157933) | |
1369 | ||
1370 | Fixed "make check" so that it compiles correctly even when e2fsprogs' | |
1371 | header files have not be installed in the system include directories. | |
1372 | (Addresses Sourceforge Bug: #1180572) | |
1373 | ||
1374 | Fixed gcc -Wall nits. | |
1375 | ||
1376 | ||
fd4b28ef TT |
1377 | E2fsprogs 1.37 (March 21, 2005) |
1378 | =============================== | |
1379 | ||
1380 | Add support for checking the validity of Extended Attributes stored in | |
1381 | inodes to e2fsck. | |
1382 | ||
1383 | Add support for dumping the contents of large inodes to debugfs, | |
1384 | including the extended attributes stored in inodes. | |
1385 | ||
1386 | Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that | |
1387 | when we create a new inode we make sure that the extra information in | |
1388 | the inode (any extra fields in a large inode and any ea-in-inode | |
1389 | information) is initialized correctly. This can take place when | |
1390 | mke2fs creates the root and lost+found directory, when e2fsck creates | |
1391 | a new root inode or a new lost+found directory, and when the user uses | |
1392 | the debugfs write, mknod, or mkdir commands. Otherwise, the newly | |
1393 | create inode could inherit garbage (or old EA information) from a | |
1394 | previously deleted inode. | |
1395 | ||
1396 | Fixed a bug in e2fsck so it would notice if a file with an extended | |
1397 | attribute block was exactly 2**32 blocks, such that i_blocks wrapped | |
1398 | to zero. | |
1399 | ||
1400 | Added support to filefrag to detect files which are using the new | |
1401 | experimental file extents format, and use the non-ext2 algorithm in | |
1402 | that case. Fixed a bug to avoid reporting a false discontinuity if | |
1403 | there is one or more unallocated blocks at the beginning of a file. | |
1404 | ||
1405 | Duplicated a check for noticing whether or not the number of blocks | |
1406 | (given a certain blocksize) is greater than 2**32 when the | |
1407 | BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This | |
1408 | allows mke2fs to automatically use a larger blocksize when creating a | |
1409 | filesystem on a very large device when run on systems that do not | |
1410 | support BLKGETSIZE64. | |
1411 | ||
1412 | Fix the I18N build which was broken in e2fsprogs 1.36 because the | |
1413 | build system had been switched to treat the .gmo files as shipped | |
1414 | files (for backwards compatibility with systems that have older GNU | |
1415 | I18N tools installed), but the gen_tarball.in script was still | |
1416 | removing the .gmo files from the official source distribution. | |
1417 | ||
1418 | Fixed various Debian packaging issues --- see debian/changelog for | |
1419 | details. (Addresses Debian Bugs ##296769, #299341) | |
1420 | ||
1421 | Programmer's notes: | |
1422 | ------------------- | |
1423 | ||
1424 | Added new functions to the e2p library which convert between a string | |
1425 | and os_type: e2p_os2string() and e2p_string2os(), and used them to | |
1426 | make the generated binaries more compact. | |
1427 | ||
1428 | Fixed a compile-time error on Darwin systems. | |
1429 | ||
1430 | Cleaned up the lib/ext2fs Makefile slightly. | |
1431 | ||
1432 | ||
3eee5e9e TT |
1433 | E2fsprogs 1.36 (February 4, 2005) |
1434 | ================================= | |
2b0dc0ac TT |
1435 | |
1436 | All of the patches that were applied to Fedore Core 3's | |
1437 | e2fsprogs-1.35-11.2 have been integrated, although sometimes with a | |
1438 | lot of bug fixes first. Users of Fedora Core 3 are strongly | |
1439 | encouraged to upgrade to e2fsprogs 1.36 as soon as possible. | |
1440 | ||
1441 | Add support for filesystem with the online resizing via resize inode | |
1442 | feature. Fixed numerous bugs from the Fedora patches. The Fedora | |
1443 | patches also didn't bother to do any consistency checking on the | |
1444 | resize inode, or add any tests to the regression test suite. The "-R | |
1445 | resize=4g" option to mke2fs was a no-op in the Fedora patches, despite | |
1446 | being listed in mke2fs's usage message. All of these shortcomings | |
1447 | have been corrected. | |
1448 | ||
1449 | E2fsck can also also fix filesystems trashed by Fedora's resize2fs | |
1450 | program. In order to do this, the user must run the commands: | |
1451 | ||
d0a3b46c | 1452 | debugfs -w /dev/hdXXX -R "features ^resize_inode" |
2b0dc0ac TT |
1453 | e2fsck -f /dev/hdXXX |
1454 | ||
1455 | Optionally, the ext2prepare command can be used to re-enable online | |
1456 | resizing after the filesystem has been fixed. | |
1457 | ||
1458 | The fsck program will now accept an optional filedescriptor argument | |
1459 | to the -C option. (The Fedora version of this patch would sometimes | |
1460 | cause fsck to ignore a parameter on fsck's command line in some rare | |
1461 | cases, sigh.) | |
1462 | ||
dc256973 TT |
1463 | Make sure e2fsprogs doesn't write garbage into the reserved portion of |
1464 | large inodes. | |
1465 | ||
1466 | Make sure resize2fs releases the blocks belonging to the old inode | |
1467 | table blocks when moving the inode table. (Addresses Debian Bug: | |
1468 | #290894) | |
1469 | ||
1470 | Skip the r_resize_inode test if resize2fs is not compiled (due to | |
1471 | configure --disable-resizer) | |
1472 | ||
1473 | E2fsck now checks the summary filesystem accounting information, and | |
1474 | if any of the information is obviously wrong, it will force a full | |
1475 | filesystem check. (Addresses Debian Bug #291571) | |
1476 | ||
1477 | Fix e2fsck to not complain when the resize_inode feature is enabled, | |
1478 | s_reserved_gdt_blocks is zero, and there is no DIND block allocated in | |
1479 | the resize inode. | |
1480 | ||
8ceb55f0 TT |
1481 | Fix e2fsck to note delete symlinks that contain an extended attribute |
1482 | after the ext_attr feature flag has been cleared. (Addresses Red Hat | |
1483 | Bugzilla #146284). | |
1484 | ||
dc256973 TT |
1485 | Add new utility program, copy_sparse.c, which is very useful |
1486 | for dealing with large sparse files (such as e2image files). | |
1487 | ||
1488 | Add support for jnl_blocks[] for debugfs's set_super_value. | |
1489 | ||
1490 | Fix filefrag so that it works correctly with sparse files. | |
1491 | ||
3eee5e9e TT |
1492 | Filefrag -v will print first and last blocks. |
1493 | ||
dc256973 TT |
1494 | Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs |
1495 | and dumpe2fs. | |
1496 | ||
8ceb55f0 TT |
1497 | Add mke2fs support so that it can support filesystems larger than 4TB |
1498 | automatically, by retrying with a 4k blocksize if the device size is | |
1499 | too big to be expressed using a 1k blocksize. (Addresses Sourceforge | |
1500 | bug #1106631) | |
1501 | ||
dc256973 TT |
1502 | Change blkid to test for NTFS first because Windows sometimes doesn't |
1503 | clear enough of the parition to confuse the probing routines into | |
1504 | thinking the old filesystem type is still valid. (Addresses Debian | |
1505 | Bug #291990) | |
1506 | ||
66fa0de8 TT |
1507 | Add support for swap partition label and uuid's in the blkid library. |
1508 | ||
dc256973 TT |
1509 | Add support to the blkid library to recognize Oracle ASM volumes. |
1510 | ||
1511 | Make blkid -t display all devices that match the specified criteria, | |
8ceb55f0 TT |
1512 | not just the first one, and work more consistently when the blkid |
1513 | cache file is not available or set to /dev/null. (Addresses Debian | |
1514 | Bug #290530 and #292425) | |
dc256973 | 1515 | |
2b0dc0ac TT |
1516 | Badblocks will now correctly display block numbers greater than |
1517 | 999,999,999 in its progress display. | |
1518 | ||
1519 | The tune2fs program will not allow the user from setting a ridiculous | |
1520 | number of reserved blocks which would cause e2fsck to assume the | |
1521 | superblock was corrupt. E2fsck's standards for what is a ridiculous | |
1522 | number of reserved block has also been relaxed to 50% of the blocks in | |
1523 | the filesystem. | |
1524 | ||
1525 | The blkid library will return vfat in preference to msdos, and ext3 in | |
1526 | preference to ext2 (if the journalling flag is set) so that mount will | |
1527 | do the right thing. (Addresses Debian bug #287455) | |
1528 | ||
1529 | Mke2fs will now use the -E option for extended options; the old -R | |
1530 | (raid options) option is still accepted for backwards compatibility. | |
1531 | Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707) | |
1532 | ||
1533 | Mke2fs will now accept a size in megabytes, gigabytes, and other units | |
1534 | (via "32m" or "4g" on the command line) if the user finds this more | |
1535 | convenient than specifying a block count. | |
1536 | ||
1537 | Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode | |
1538 | cache conherency problem. | |
1539 | ||
1540 | Debugfs now supports a new command, set_inode_field, which allows a | |
1541 | user to manually set a specific inode field more conveniently, as well | |
1542 | as set entries in the indirect block map. | |
1543 | ||
1544 | Debugfs's set_super_value command has been enhanced so that the user | |
1545 | can set most superblock fields, including the date/time fields and | |
1546 | some of the more newsly added superblock fields. | |
1547 | ||
1548 | E2fsprogs programs now accept an offset to be passed to the file | |
1549 | specifiers, via the syntax: "/tmp/test.img?offset=1024". | |
1550 | ||
1551 | E2fsprogs programs will now accept blocksizes up to 65536; kernel | |
1552 | support on the x86 doesn't exist for now, but it can be useful on | |
8ceb55f0 TT |
1553 | other architectures with page sizes greater than 4k. There are 2.6 |
1554 | kernel patches out there which enable this, but they are of this | |
1555 | writing still experimental. | |
2b0dc0ac | 1556 | |
4ee558fc TT |
1557 | The e2image command now takes the -s option which will scramble |
1558 | directory entries for raw image files. | |
1559 | ||
1560 | Fix a file descriptor leak in the filefrag program. | |
1561 | ||
1562 | Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not | |
1563 | present. | |
1564 | ||
2b0dc0ac TT |
1565 | Fix bug in debugfs where kill_file would lead to errors when deleting |
1566 | devices and symlinks. (Sourceforge Bugs #954741 and #957244) | |
1567 | ||
1568 | Fix bug in the blkid library when detecting the ocfs1 filesystem | |
1569 | ||
1570 | Remove obsolete EVMS 1.x and a.out DLL support. | |
1571 | ||
1572 | E2fsck will attempt to recover from a journal containing illegal blocks. | |
48301129 TT |
1573 | |
1574 | Fixed two potential ordering constraint problems in e2fsck which might | |
1575 | cause the filesystem to be corrupted if e2fsck is interrupted during a | |
1576 | (extremely narrow) race window. Thanks to Junfeng Yang from the | |
1577 | Stanford Metacompilation group for pointing this out. | |
1578 | ||
1579 | Fixed bug in e2fsck where it would not accurately detect whether or | |
1580 | not the system is running on adaptor if the ACPI device representing | |
1581 | the AC adapter didn't correspond to the what was used on IBM | |
1582 | Thinkpads. | |
1583 | ||
1584 | Change e2fsck to accept directories greater than 32MB. | |
1585 | ||
1586 | Fix e2fsck so that a checkinterval of zero disables a time-based check | |
1587 | of the filesystem. | |
1588 | ||
1589 | Debugfs will check the DEBUGFS_PAGER enviroment variable in preference | |
1590 | to the PAGER environment variable. (Addresses Debian Bug #239547) | |
1591 | ||
1592 | Tune2fs will not mark rewrite the superblock if the feature bitmasks | |
1593 | are not modified. | |
1594 | ||
1595 | The debugfs program will set the filetype information when creating a | |
1596 | link. | |
1597 | ||
1598 | Add debugfs -d option to use a separate source of data blocks when | |
1599 | reading from an e2image file. | |
1600 | ||
1601 | Add e2image -I option which allows the e2image metadata to be | |
1602 | installed into a filesystem. | |
1603 | ||
1604 | Fixed bug in the badblocks program which caused "done" to always | |
1605 | appear in english even when a translation was available. (Addresses | |
1606 | Debian Bug #252836) | |
1607 | ||
1608 | The blkid program has a new option -o which controls the output format | |
1609 | of the blkid program; this is makes blkid more convenient to use in | |
1610 | shell scripts. | |
1611 | ||
1612 | Fix a minor bug in uuid library, which was not using the full 14 bits | |
1613 | of clock sequence when generating UUID's. | |
1614 | ||
1615 | Fix a Y8.8888K problem in the uuid library. | |
1616 | ||
1617 | Logsave now creates a new session id for itself to avoid getting | |
1618 | killed by init whan transitioning between init levels. | |
1619 | ||
1620 | Change the licensing of the UUID library to be the 3-clause BSD-style | |
1621 | license; this allows Apple to use the uuid library in Darwin. | |
1622 | ||
1623 | Add ocfs and ocfs2 probe support into the blkid library. | |
1624 | ||
1625 | Fix a memory and file descriptor leak in the blkid library. | |
1626 | ||
1627 | The blkid library will revalidate the device if the system time is | |
1628 | earlier than last verification time of the device, since that | |
1629 | indicates that the system time is probably nottrustworthy. | |
1630 | ||
1631 | The blkid library will override the default location of the blkid.tab | |
1632 | file by the BLKID_FILE environment variable, if it is available. | |
1633 | ||
1634 | Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6. | |
1635 | ||
1636 | Add various portability fixes for lame new versions of glibc, Darwin | |
1637 | and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian | |
2b0dc0ac TT |
1638 | Bugs #239934, #264630, #269044, #255589, #289133) |

1640 | Add support for Windows 9x/NT under Cygwin. | |
48301129 TT |
1641 | |
1642 | Updated and clarified various man pages. (Addresses Debian Bugs #236383, | |
2b0dc0ac | 1643 | #241940, #238741, #242995, #256669, #268148, #256760, #273679) |

1644 | |
1645 | Updated and fixed translations. (Addresses Debian bugs #244105, #262836) | |
1646 | ||
1647 | Update the rpm spec files so that it works better with Fedora core 2 | |
1648 | and RH9. | |
1649 | ||
1650 | Fixed various Debian packaging issues (see debian/changelog). In | |
1651 | particular, fixed the Debian initrd scripts. (#241183, #248050, | |
1652 | #253595, #247775) | |

1655 | Programmer's notes: | |
1656 | ------------------- | |
1657 | ||
2b0dc0ac | 1658 | Fixed various gcc -Wall warnings. |
48301129 TT |
1659 | |
1660 | The uuid library now has new functions uuid_unparse_upper() and | |
1661 | uuid_unparse_lower() which forces the case of the hex digits to be | |
1662 | upper case, or lower case. | |
1663 | ||
1664 | The build process has been speeded up by enhancing the subst program | |
1665 | to update the modtime on the generated files even when the generated | |
1666 | file hasn't changed. | |
1667 | ||
1668 | The uuid library now uses C99 stdint.h types instead of custom types. | |
1669 | ||
1670 | Updated config.guess and config.sub with newer versions from the FSF. | |
1671 | ||
1672 | Removed out of date .cvsignore files from the source distribution. | |
1673 | ||
2b0dc0ac TT |
1674 | The ext2fs_unlink() function will return an error if both the name and |
1675 | inode number are unspecified, to avoid doing something surprising | |
1676 | (such as unconditionally deleting the first directory entry). | |
1677 | Directory entries are now deleted by coalescing them with the previous | |
1678 | directory entry if possible, to avoid directory fragmentation. This | |
1679 | is not an issue with the e2fsprogs suite, but may be a problem for | |
1680 | some of the users of libext2fs, such as e2tools. | |
1681 | ||
1682 | Add support for version numbers of the form "1.36-rc1". | |
1683 | ||
48301129 TT |
1684 | Fix build of mke2fs.static. |
1685 | ||
dc256973 TT |
1686 | Add basic ext2fs library support for large (EA in inode) inodes. |
1687 | ||
48301129 TT |
1688 | The test_io mechanism can now abort after n reads or writes to a |
1689 | particular block. The block is specified by TEST_IO_BLOCK environment | |
1690 | variable, and the read/write count by the TEST_IO_READ_ABORT and | |
1691 | TEST_IO_WRITE_ABORT environment variables. The block data is now only | |
1692 | dumped if the 0x10 bit is set in TEST_IO_FLAGS. | |
1693 | ||
1694 | UUID_DEFINE() in the uuid library now creates a static variable, with | |
1695 | __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can | |
1696 | be used in header files. | |
1697 | ||
2b0dc0ac TT |
1698 | Add support for the install-strip and install-shlibs-strip targets, as |
1699 | suggested by the GNU coding guielines. "make install" no longer | |
1700 | strips the binaries which are installed. | |
1701 | ||
3eee5e9e TT |
1702 | Remove support for the --enable-old-bitops configure option which was |
1703 | only for very old sparc systems. | |
1704 | ||
1705 | Remove support for --enable-clear-htree; this was only needed during | |
1706 | the early development of the htree patch. | |
1707 | ||
2b0dc0ac TT |
1708 | Use Linux-kernel-style makefile output so it is easier to see compiler |
1709 | warnings. | |
1710 | ||
1711 | Update gettext files to version 0.14.1. | |
1712 | ||
1713 | Update to use autoconf 2.5x. | |
1714 | ||
1715 | Improved support for compiling e2fsprogs under dietlibc. | |
1716 | ||
4ee558fc TT |
1717 | Make e2fsprogs portable to Solaris and FreeBSD systems. |
1718 | ||
8ceb55f0 TT |
1719 | Add blkid_verify(), blkid_get_library_version(), and |
1720 | blkid_parse_version_string() functions to the blkid library. | |
dc256973 TT |
1721 | |
1722 | Add pkg-config files for e2fsprogs's libraries. | |
1723 | ||
1724 | Fix "make uninstall" to so that it removes everything that is installed. | |
1725 | ||
3eee5e9e TT |
1726 | Add a configure --enable-maintainer-mode option which enables the |
1727 | makefile rules to rebuild the configure script from configure.in, and | |
1728 | to reubuild the .gmo files in po directory. | |
1729 | ||
1730 | Drop the sparc assembly bitwise operations; it's less efficient | |
1731 | than the GCC 3.4 compile code and triggers compiler warnings on | |
1732 | sparc64. Thanks to Matthias Andree for his analysis and suggestions. | |

1736 | E2fsprogs 1.35 (February 28, 2004) |
1737 | ================================== | |
1738 | ||
48301129 | 1739 | E2fsck has a new -k option, which in conjunction with the -c options, |
b70b1167 TT |
1740 | preserves the existing badblocks list. |
1741 | ||
48301129 | 1742 | Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d. |
b70b1167 TT |
1743 | |
1744 | E2fsprogs will now deal correctly with symlinks that contain | |
1745 | extended attribute information, which can be created using SE Linux. | |
1746 | (Addresses Debian Bug #232328) | |
1747 | ||
1748 | Remove a double longjump into an invalid stack frame bug in e2fsck. | |
1749 | (This was during an abort sequence, which normally worked on Linux and | |
1750 | caused a core dump on other operating systems.) | |
c4c30b20 | 1751 | |
1daf7585 TT |
1752 | Fix NLS bug in e2fsck, by avoiding trying to expand an empty string |
1753 | (the NLS library will replace "" with the .po header information). | |
1754 | ||
c4c30b20 TT |
1755 | Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core |
1756 | dump due to a division by zero error. (Addresses Debian bug #207082) | |
1757 | ||
151a7162 TT |
1758 | Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem |
1759 | when reconnecting a directory requires creating a lost+found | |
1760 | directory. (Addresses Debian bug #219640). | |
1761 | ||
1762 | Fixed a bug where e2fsck would bomb out if a journal needed to be | |
1763 | replayed when using an alternate superblock. | |
1764 | ||
48301129 | 1765 | E2fsck will give an extra grace period before actually forcing a check |
c4c30b20 TT |
1766 | if the laptop is running on battery. The next time fsck runs while |
1767 | the system is on the AC mains, or after the grace period is exceeded, | |
1768 | the filesystem will be checked. (Addresses Debian bug #205177) | |
1769 | ||
1770 | E2fsck will inform the user when there are 5 or fewer mounts before a | |
1771 | filesystem check will be forced. (Addresses Debian bug #157194) | |
1772 | ||
1773 | Fix e2fsck's handling of corrupted indirect blocks in the bad block. | |
1774 | We now correctly handle the case where there is an overlap between a | |
1775 | block group descriptor or a superblock and a bad block indirect block. | |
1776 | In the case where the indirect block is corrupted, we now suggest | |
1777 | "e2fsck -c". | |
1778 | ||
1daf7585 TT |
1779 | Fix byte swap bugs in e2fsck that caused the journal backup location |
1780 | in the superblock and symlinks created by SE Linux to be cleared | |
1781 | by e2fsck on big-endian machines. (Addresses Debian bug #228723) | |
1782 | ||
c4c30b20 TT |
1783 | E2fsck -c now replaces the current list of bad blocks with the ones |
1784 | found by badblocks. | |
1785 | ||
1786 | Fix bugs in e2fsck and tune2fs which could cause a core dump if a | |
1787 | non-existent LABEL or UUID specifier is to e2fsck or tune2fs. | |
1788 | ||
1789 | Fix a potential bug in e2fsck which could cause it to core dump when | |
1790 | trying to print the location of the backup superblock. | |
1791 | ||
1792 | Protect against a potential core dump in e2fsck when printing a | |
1793 | message about backup superblocks. | |
858dd7b1 | 1794 | |
6826bde5 TT |
1795 | Add support for backing up the journal inode location in the |
1796 | superblock. E2fsck will automatically save the journal information in | |
1797 | the superblock if it is not there already, and will use it if the | |
1798 | journal inode appears to be corrupted. ext2fs_add_journal_inode() | |
1799 | will also save the backup information, so that new filesystems created | |
1800 | by mke2fs and filesystems that have journals added via tune2fs will | |
1801 | also have journal location written to the superblock as well. | |
1802 | Debugfs's logdump command has been enhanced so that it can use the | |
1803 | journal information in the superblock. | |
c4c30b20 TT |
1804 | |
1805 | E2fsck will now update all superblocks when moving the journal inode. | |
6826bde5 TT |
1806 | |
1807 | Shrink the size of the e2fsck executable by moving some initialized | |
1808 | variables to the BSS segment. | |
1809 | ||
1810 | E2fsck will avoid printing the ^A and ^B characters which bracket the | |
1811 | progress bar when stdout and stdin are a tty device instead of a pipe | |
1812 | to another program. (Addresses Debian bug #204137) | |
1813 | ||
151a7162 TT |
1814 | Debugfs's mkdir command will automatically expand the directory if |
1815 | necessary. (Addresses Debian Bug: #217892) | |
1816 | ||
1817 | Fixed a bug in debugfs so that copying a file from /dev/null uses the | |
1818 | correct mode bits. (Addresses Debian Bug: #217456) | |
1819 | ||
1820 | If the environment variables DEBUFS_PAGER and PAGER are not set, | |
1821 | debugfs now searches for the appropriate pager to use, beginning with | |
2b5ddd75 | 1822 | /usr/bin/pager, and then falling back to 'more' and 'less'. |
1daf7585 TT |
1823 | (Addresses Debian bug #221977) |
1824 | ||
b70b1167 TT |
1825 | Debugfs will now support 2.6 device numbers where the major or minor |
1826 | number may be larger than 255. (Addresses Sourceforge bug #865289) | |
1827 | ||

151a7162 | 1832 | |
858dd7b1 TT |
1833 | Fix regression tests so they work correctly when e2fsprogs is compiled |
1834 | with configure --disable-htree. | |
1835 | ||
1daf7585 TT |
1836 | Fix bug in uuid library when there is no network card and the library |
1837 | is generating a time-based uuid. The random MAC address was not | |
1838 | correctly generated to be a multicast address. | |
1839 | ||
858dd7b1 | 1840 | Add compile_et extensions from Heimdall that were missed the first time |
48301129 | 1841 | around. |
858dd7b1 TT |
1842 | |
1843 | Fix bug in badblocks when using O_DIRECT; we need to make sure that | |
1844 | we're reading from an offset which is page aligned. For read-only and | |
1845 | read-write tests, we try to recover after an error so that we can | |
1846 | continue reading on page-aligned boundaries. (Addresses Debian Bug | |
1847 | #203713) | |

1859 | Programmer's notes: | |
1860 | ------------------- | |
1861 | ||
b70b1167 TT |
1862 | Fixed a build problem so that e2fsprogs would compile with the |
1863 | --enable-profile option to configure selected. (Addresses Sourceforge | |
1864 | bug #811408) | |
1865 | ||
1866 | Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat | |
1867 | Bugzilla Bug #112448) | |
1868 | ||
c4c30b20 TT |
1869 | Centralize code which calculates the location of the superblock |
1870 | and block group descriptors so that it is in a single library routine. | |
1871 | ||
6826bde5 TT |
1872 | Added two new functions, ext2fs_file_open2() and |
1873 | ext2fs_inode_io_intern2() which take a pointer to an inode structure. | |
1874 | ||
1875 | Fix compile_et to output the correct prototype for | |
1876 | initialize_xxx_err_table_r() in the header file. (Addresses Debian | |
1877 | bug #204332) | |
1878 | ||
1879 | In the lib/et makefile, make sure com_err.info is deleted on "make clean". | |
1880 | ||
858dd7b1 TT |
1881 | Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if |
1882 | present. This is for when we try stuffing an int into void * pointer. | |
1883 | ||
1884 | Fix type-punning which can cause gcc 3.x to miscompile code by getting | |
1885 | confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(), | |
1886 | and ext2fs_resize_mem() all now take a 'void *' instead of a 'void | |
1887 | **'. The EVMS code uses an ugly union approach since we don't want to | |
1888 | modify the EVMS interfaces. | |
1889 | ||
1890 | Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to | |
1891 | aid build process on systems can use invoke GNU make as "gmake". | |
1892 | ||

9c7ec178 TT |
1903 | E2fsprogs 1.34 (July 25, 2003) |
1904 | =============================== | |
1905 | ||
1906 | Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in | |
1907 | a tight loop while waiting for a child fsck to exit in some cases. | |
1908 | This burns CPU times which slows down the low-level filesystem check. | |
1909 | ||
1910 | Added code to mke2fs to assure that the default block size for a | |
1911 | filesystem is at least as big as the sector size of the device, if it | |
1912 | can be determined. | |
1913 | ||
1914 | Changed mke2fs and resize2fs to round the default size of a filesystem | |
1915 | to be an even multiple of the VM pagesize in order to avoid a Linux | |
1916 | kernel bug introduced when the storage of the buffer cache was moved | |
1917 | into the page cache. | |
1918 | ||
1919 | Mke2fs will warn the user when creating a filesystem with journaling | |
1920 | and a blocksize greater than 4096. (Addresses Debian bug #193773) | |
1921 | ||
1922 | Fixed a bug in resize2fs which caused it to fail on filesystems with a | |
1923 | non-empty bad block list. Resize2fs now discards any blocks on the | |
1924 | badblock list which are no longer part of the filesystem as the result | |
1925 | of a filesystem shrink. (Note: this means that shrinking and then | |
1926 | enlarging a filesystem is no longer a reversible operation; | |
1927 | information about bad blocks in the part of the filesystem which is to | |
1928 | be chopped off will be lost.) | |
1929 | ||
1930 | Changed resize2fs so the user can use prefixes to specify the units of | |
1931 | the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), | |
1932 | and to make the error and informational messages explicitly display | |
1933 | the blocksize used by the filesystem, in order to avoid confusion. | |
1934 | (Addresses Debian bug: #189814) | |
1935 | ||
1936 | Added a new debugfs command, dump_unused, which dumps the contents of | |
1937 | all unused blocks to stdout. (Useful as an emergency try-to-find | |
1938 | deleted data command.) | |
1939 | ||
1940 | Added a new debugfs command, imap, which prints the location of a | |
1941 | specified inode in the inode table. | |
1942 | ||
1943 | Fixed a bug in the badblocks program which caused it to use one bit of | |
1944 | randomness in its non-destructive read/write test, instead of using a | |
1945 | full 8 bits of randomness. | |
1946 | ||
1947 | Added a new option (-t) to badblocks, which allows the user to control | |
1948 | the test pattern(s) used when checking a disk. | |
1949 | ||
1950 | The blkid probe function now more correctly detects UDF filesystems. | |
1951 | ||
1952 | Fixed a bug in the blkid library which caused it to not update its | |
1953 | cache if a filesystem changes from having a label to not having a | |
1954 | label. | |
1955 | ||
1956 | Fixed a bug in the blkid library wihch could avoid an infinite loop | |
1957 | in blkid_find_dev_with_tag() if /proc is not mounted and there the | |
1958 | /etc/blkid.tab file has not yet been created. | |
1959 | ||
1960 | Fixed the badblocks program so that the destructive read/write test | |
1961 | honors the -c option, and to use O_DIRECT when possible to avoid | |
1962 | thrashing the system block buffer cache. | |
1963 | ||
1964 | Fixed various NLS issues. | |
c8a40402 | 1965 | - Added Czech and Swedish translations |
9c7ec178 TT |
1966 | - Removed testing NYC translation |
1967 | - Fixed NLS support for message abbrevations in e2fsck | |
1968 | - Remove de-utf.po, since we shouldn't have two versions using different | |
1969 | charset encodings. | |
1970 | - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to | |
1971 | simplify the statistics reporting in e2fsck. | |
1972 | ||
1973 | Changed configure.in so that its defaults for *BSD systems no longer | |
1974 | build an fsck wrapper, and not to install in /usr/local by default. | |
1975 | ||
1976 | Fixed some minor spelling errors/typo's in e2fsck and the configure | |
1977 | script. | |
1978 | ||
1979 | Fixed various Debian packaging issues (see debian/changelog). | |
1980 | ||
1981 | Updated and clarified man pages. (Addresses Debian Bug #195616) | |
1982 | ||
1983 | Programmer's notes: | |
1984 | ------------------- | |
1985 | ||
1986 | Fix gcc -Wall nitpicks. | |
1987 | ||
1988 | Updated gettext implementation used by e2fsprogs to 0.11.5, and enable | |
1989 | NLS support by default. (Added partial workaround for gettext/Darwin | |
1990 | incompatibility problems.) | |
1991 | ||
1992 | Added full MIT KRB5 and Himdall compaibility support to the com_err | |
1993 | library and the compile_et program. (Addresses Debian bug #191900) | |
1994 | ||
1995 | Added the blkid_known_fstype() function to the blkid library, which | |
1996 | returns true if it is passed a filesystem type which is recognized by | |
1997 | the blkid probing functions. | |
1998 | ||
1999 | Improved the documentation for the blkid library. | |
2000 | ||
2001 | Added the ext2fs_get_device_sectsize() function the the ext2fs library, which | |
2002 | returns the hardware sector size of a device, if it is available. | |
2003 | ||
2004 | Added a dependency in the blkid library's .so file to the uuid | |
2005 | library, since the former uses the latter. (Addresses Debian bug | |
2006 | #194094) | |
2007 | ||
2008 | Added --with-diet-libc and --disable-evms to the configure script. | |
2009 | ||
2010 | Fixed a minor memory leak in the badblocks program. | |
2011 | ||
2012 | Fixed a portability problem in tune2fs --- not all systems have strptime(). | |
2013 | ||
2014 | Fixed a portability problem in debugfs with the use of getopt() more | |
2015 | than once. Old-style BSD, new-style BSD, and Linux C libraries all do | |
2016 | things differently. | |
2017 | ||
2018 | Add support Windows support to ext2fs_get_device_size(). | |
2019 | ||
2020 | Added (normally disabled) debugging code to the Unix I/O manager which | |
2021 | causes it to disable all userspace caching if the NO_IO_CACHE is | |
2022 | defined. | |
2023 | ||
2024 | Changed the test I/O manager so it can always be linked into e2fsck, | |
2025 | mke2fs, and tune2fs if enabled via --enable-test-io-debug to the | |
2026 | configure script. The test I/O manager will only print any debugging | |
2027 | information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment | |
2028 | variables are set, which specifies which I/O operations are logged and | |
2029 | a block number to watch, respectively. The log messages are sent to | |
2030 | stderr by default, unless a filename is specified via the | |
2031 | TEST_IO_LOGFILE environment variable. | |
2032 | ||
2033 | ||
71df0dc3 | 2034 | E2fsprogs 1.33 (April 21, 2003) |
9c7ec178 | 2035 | =============================== |
508d7f3c | 2036 | |
ba142c1b TT |
2037 | Added a new utility program, logsave, which captures the output of a |
2038 | command in a log file, even if the containing directory hasn't been | |
2039 | mounted yet (in which case the it saves the output in memory until it | |
2040 | can write out the logfile). This is useful for capturing the | |
2041 | output of fsck during the boot sequence. | |
2042 | ||
2043 | Fixed some portability problems that were causing problems under | |
2044 | the Cygwin32 environment. | |
2045 | ||
2046 | Mke2fs now interprets a negative number to the -b option as a minimum | |
2047 | block size. | |
2048 | ||
2049 | Fixed a bug in mke2fs which was incorrectly checking the argument to | |
2050 | the -g option if the default block size was used. (Addresses Debian | |
2051 | bug #188319) | |
2052 | ||
2053 | Fsck now explicitly ignores tmpfs and devpts, and it will complain if | |
2054 | it can not find filesystem checkers for jfs, reseirfs, and xfs. | |
2055 | ||
2056 | E2fsck now updates the global free block and inode counters from the | |
2057 | block group specific counters quietly. This is needed for an | |
2058 | experimental patch which eliminates locking the entire filesystem when | |
2059 | allocating blocks or inodes; if the filesystem is not unmounted | |
2060 | cleanly, the global counts may not be accurate. | |
2061 | ||
2062 | Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS | |
2063 | 2.0 is not yet supported; this only pulled in the bug fixes: fixed | |
2064 | possible hangs caused by bugs in calling waitpid, and not setting the | |
2065 | pipe to non-blocking mode; also fixed a file descriptor leak; made | |
2066 | sure all functions call log entry/exit functions.) | |
2067 | ||
2068 | Badblocks now flushes its output file as bad blocks are discovered. | |
2069 | ||
2070 | The uuid library is now more paranoid about assuming the correctness | |
2071 | of the /dev/random device; it mixes in a stream of bytes from | |
2072 | random/srandom, just in case. | |
2073 | ||
39d38b05 | 2074 | Update Debian files to reflect the fact that I am now the Debian |
ba142c1b TT |
2075 | maintainer of e2fsprogs. Other various Debian-specific packaging |
2076 | cleanups. | |
39d38b05 TT |
2077 | |
2078 | Move the source tarball generation functions from the top-level | |
2079 | makefile to the util/gen-tarball script. | |
2080 | ||
2081 | Updated the Turkish .po translation file. | |
2082 | ||
1daf7585 | 2083 | Added Heimdal and MIT krb5 extensions to the com_err library to make |
39d38b05 TT |
2084 | it more compatible with com_err libraries from those distributions. |
2085 | ||
2086 | Changed dumpe2fs to always display the superblock fields relating to | |
2087 | the journalling and/or directory indexing feature even if those | |
2088 | features are not enabled. | |
2089 | ||
508d7f3c TT |
2090 | Updated and clarify copyright statement vis-a-vis alpha releases of |
2091 | e2fsprogs. | |
2092 | ||
2093 | The ss library will now try to dynamically link to the readline | |
2094 | library and use it if it is present in the system. This means that | |
ba142c1b TT |
2095 | the debugfs program now has line editing and history features. The |
2096 | SS_READLINE_PATH environment variable is used to find a readline or | |
2097 | readline-compatible library. | |
3809bf1d | 2098 | |
e5dced7f TT |
2099 | E2fsck now finds most duplicate filenames (all when rebuilding all |
2100 | directories via the -D option) and offers to delete or rename | |
2101 | duplicate filenames/directory entries. (Addresses Debian Bug #176814). | |
2102 | ||
2103 | Fix bug in e2image. When writing out a raw image file, include data | |
2104 | blocks from symlinks that do not store the symlink within the inode. | |
2105 | ||
3809bf1d TT |
2106 | Fix bug in resize2fs which incorrectly moved the block and inode |
2107 | bitmaps for sparse superblock filesystems and incorrectly marked | |
2108 | blocks as in use. (Addresses Debian bug #174766) | |
2109 | ||
2110 | Added a new shared library, the blkid library, which efficiently | |
2111 | allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL | |
2112 | and UUID filesystem specifiers without needing to search all of the | |
2113 | devices in the system. Instead, the device is looked up in a cache | |
2114 | file, and then verified to make sure the blkid cache is correct. | |
2115 | ||
2116 | Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for | |
2117 | the device name, using the blkid library. (Addresses Debian bugs | |
2118 | #166048, #179671) | |
2119 | ||
2120 | Fsck now supports backslash escapes in /etc/fstab so that \040 can be | |
2121 | used for spaces in device labels. | |
2122 | ||
2123 | Removed 32-bit limitations for debugfs's dump command. | |
2124 | ||
2125 | If the user specifies a large number of inodes, Mke2fs will | |
2126 | automatically adjust the number of blocks per group to find a valid | |
2127 | set of filesystem parameters. | |
2128 | ||
2129 | Add workaround to detect broken MD devices where when some of the | |
2130 | underlying devices are marked read-only, writes to the MD device are | |
2131 | silently dropped. E2fsck will detect if there is an attempt to run | |
2132 | the journal twice, and abort with an error if this is the case. | |
2133 | (Addresses IBM Bugzilla bug #1226) | |
2134 | ||
2135 | E2fsck will print an error if more than one of the -p/-a, -n or -y | |
2136 | options are specified. | |
2137 | ||
2138 | E2fsck will fix HTREE corruptions in preen mode, without stopping the | |
2139 | boot process. This is needed because the 2.4 ext2 filesystem | |
2140 | accidentally had the INDEX_FL backwards compatibility code removed. | |
2141 | ||
2142 | Mke2fs no longer creates filesystems with the dir_index flag set by | |
2143 | default; the user has to specifically request it. | |
2144 | ||
2145 | Update and clarified various man pages. (Addresses Debian bugs | |
ba142c1b | 2146 | #173612, #175233, #175113, and #170497, #185945, #188318) |
3809bf1d | 2147 | |
508d7f3c TT |
2148 | Created man page for the mk_cmds program (from the libss library). |
2149 | ||
3809bf1d TT |
2150 | Programmer's notes: |
2151 | ------------------- | |
2152 | ||
2153 | Fix various gcc -Wall nits. | |
2154 | ||
2155 | Fixed a lot of portability problems that caused e2fsprogs not to build | |
e5dced7f TT |
2156 | successfully under Solaris and Apple/Darwin. |
2157 | ||
2158 | Fixed a Makefile dependency to allow building e2fsprogs using parallel | |
2159 | make jobs. | |
3809bf1d TT |
2160 | |
2161 | Changes to create a subset distribution which consists only of the | |
2162 | et, ss, uuid, and blkid libraries. The configure script and top-level | |
2163 | makefile were changed to support working with a subset distribution. | |
2164 | ||
ba142c1b TT |
2165 | Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not |
2166 | actually used, and might people who are looking for | |
2167 | EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use. | |
2168 | ||
508d7f3c TT |
2169 | Updated debian files to fix a number of Lintian warnings. |
2170 | ||
2171 | Updated config.guess and config.sub with newer versions from the FSF. | |
3809bf1d | 2172 | |
71df0dc3 TT |
2173 | Removed unnecessary libraries from being linked into the fsck, lsattr, |
2174 | chattr, and blkid executables. | |
2175 | ||
38513011 TT |
2176 | E2fsprogs 1.32 (Nomvember 9, 2002) |
2177 | ================================== | |
2178 | ||
2179 | Fixed a bug in the Unix I/O routines which caused needless writebacks | |
2180 | of clean blocks from the unix_io cache (they were erroneously marked | |
2181 | as being dirty, so they were getting written back to disk before | |
2182 | getting evicted from the disk cache). This was harmless, but it | |
2183 | significantly slowed down e2fsck. | |
2184 | ||
2185 | Made some other minor optimizations to the Unix I/O routines to save a | |
2186 | small amount of CPU time. | |
2187 | ||
2188 | Updated internationalization files. | |
2189 | ||
3809bf1d | 2190 | |
ae65b29f TT |
2191 | E2fsprogs 1.31 (Nomvember 8, 2002) |
2192 | ================================== | |
2193 | ||
2194 | Update EVMS ext2fsim plugin with EVMS 1.2. (We still support | |
2195 | compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error | |
2196 | handling for child process that die unexpectly. Add a hack to force | |
2197 | mkfs to create filesystems that won't cause problems with hardware | |
2198 | that has 2k or 4k minimum blocksize requirements. Read from child | |
2199 | processes in non-blocking mode, so that the GUI continues to update. | |
2200 | ||
2201 | Fix e2fsck so that it returns the appropriate exit code when the root | |
2202 | filesystem has been changed, so that system's rc scripts will be told that | |
2203 | the system needs to be rebooted. | |
2204 | ||
2205 | Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag | |
2206 | was set, some of the descriptor blocks that should have been written | |
2207 | out were getting skipped. | |
2208 | ||
2209 | Changed e2fsck to force out changes to the backup copies of the | |
2210 | superblock and block group descriptors when important changes are made | |
2211 | to those data structures. | |
2212 | ||
2213 | Fix a bug where e2fsck could erroneously mark a filesystem as being | |
2214 | clean if a check of dirty filesystem is interrupted with a ^C. (Bug | |
2215 | introduced in e2fsprogs 1.28.) | |
2216 | ||
2217 | If journal debuging is enabled using --enable-jbd-debug, the debugging | |
2218 | level is now set via the E2FSCK_JBD_DEBUG environment variable. | |
2219 | ||
2220 | If byteswapping support is disabled using configure --disable-swapfs, | |
2221 | skip the tests which depend on byte-swapping, so that "make check" | |
2222 | won't bomb out. | |
2223 | ||
2224 | Lshattr will now display the indexed directory flag. Also, some of | |
2225 | the more esoteric compression flags are supressed unless compression | |
2226 | support has been enabled. | |
2227 | ||
2228 | Update man pages. | |
2229 | ||
2230 | ||
5d823a47 TT |
2231 | E2fsprogs 1.30 (October 31, 2002) |
2232 | ================================= | |
2233 | ||
2234 | When resizing a filesystem, and inodes need to moved, resize2fs will | |
2235 | update the inode's ctime field, and the mtime field of the containing | |
2236 | directories, so that incremental backups using dump/restore will work | |
2237 | correctly. | |
2238 | ||
2239 | In order to avoid spurious errors, e2fsck wil check the last | |
2240 | superblock write time to determine whether or not it can safely use | |
2241 | the LOW_DTIME checks to determine if there are inodes on the orphan | |
2242 | inode linked list that had somehow gotten disconnected. (Addresses | |
2243 | Sourceforge bug #620980) | |
2244 | ||
2245 | Partition in /proc/partitions that being with the string "lvm" are | |
2246 | considered real partitions even if they do not end with a number. | |
2247 | ||
2248 | Fixed a bug in the the uuid generation function, where if /dev/urandom | |
2249 | is not present, but /dev/random is, and there isn't sufficient | |
2250 | entropy, the get_random_byte function could spin a loop forever. | |
2251 | ||
2252 | E2fsck, mke2fs, etc. will now reliably notice when image files are | |
2253 | mounted using the loopback interface. (Addresses Sourceforge bug | |
2254 | #619119) | |
2255 | ||
2256 | When flushing buffers (as is done by badblocks, for example) check to | |
2257 | see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the | |
2258 | FDFLUSH ioctl which causes the MD device driver which causes confusing | |
2259 | syslog messages about obselete ioctl messages. (Addresses Sourceforge | |
2260 | bug #545832). | |
2261 | ||
2262 | Debugfs's write command now checks to see if the destination filename | |
2263 | exists before creating it. (Addresses Sourceforge bug #478195.) | |
2264 | ||
2265 | When installing man pages, search for compressed man pages using all | |
2266 | commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.) | |
2267 | ||
2268 | Fixed a bug in fsck where multiple filesystems specified on the | |
2269 | command were not being checked in parallel due to a logic bug | |
2270 | introduced to support the FSCK_MAX_INST environment variable. | |
2271 | ||
2272 | We have added a new superblock field, s_mkfs_time, which indicates | |
2273 | when a filesystem was created. It is set via mke2fs, and printed out | |
2274 | by dumpe2fs, but is not actually touched by the kernel. | |
2275 | ||
2276 | Dumpe2fs has been made more robust by not aborting if there is an | |
2277 | error reading the block/inode bitmaps; instead it will still print out | |
2278 | the location of the block/inode bitmaps and inode table. | |
2279 | ||
2280 | Add support for the an alternative block group descriptor layout which | |
2281 | allows for on-line resizing without needing to prepare the filesystem | |
2282 | in advance. (This is the incomat feature flag meta_bg.) | |
2283 | ||
2284 | Add support for storing default mount options in the superblock, so | |
2285 | that the filesystem can be mounted with specific mount options without | |
2286 | needing to specify them on the mount command line or in the /etc/fstab | |
2287 | file. | |
2288 | ||
2289 | Add support for a new inode flag, which is to be used for indicating | |
2290 | the top of directory hierarchies for the Orlov block allocator. | |
2291 | ||
2292 | Fix e2fsck so that if it creates the lost+found directory, it does so | |
2293 | with the more apporpriate permissions of 0700. Also change | |
2294 | mklost+found so that it also creates the directory 0700. | |
2295 | ||
2296 | Fixed format bug in e2fsck if NLS is in use. | |
2297 | ||
2298 | Add a German translation for e2fsprogs's NLS support. | |
2299 | ||
2300 | Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at | |
2301 | the beginning of the inode table. This won't matter much, since if | |
2302 | there is a bad block at the beginning of the inode table, the root | |
2303 | directory won't be available. But at least e2fsck won't crash in this | |
2304 | case. | |
2305 | ||
2306 | Fixed endian problems in the htree code for e2fsck and debugfs. | |
2307 | ||
2308 | When byte-swapping a filesystem on a PPC architecture, byte-swap the | |
2309 | bitmaps since the historical big-endian ext2 variant had byte-swapped | |
2310 | bitmaps, and the ext2fs library assumes this. This fixes the | |
2311 | regression test suite on PPC machines. | |
2312 | ||
2313 | Fix e2image so that it handles a bad block in the inode table | |
2314 | appropriately. | |
d5e7810e TT |
2315 | |
2316 | E2fsck now uses a more sophisticated algorithm to salvage corrupted | |
2317 | directories that recovers more information in the corrupted directory | |
2318 | block. | |
2319 | ||
2320 | E2fsck now performs additional consistency checks on indexed (HTREE) | |
2321 | directories. | |
2322 | ||
2323 | Fix bug where efsck might get confused about whether a completely | |
2324 | empty directory block is an empty leaf block or an interior htree | |
2325 | node. This could cause e2fsck to get confused into think that a valid | |
2326 | indexed directory was corrupted. | |
2327 | ||
2328 | E2fsck no longer creates an empty directory entry at the end of a | |
2329 | directory block when optimizing a directory. This would cause some | |
2330 | earlier versions of the dxdir kernel code to corrupt the directory | |
2331 | when attempting to split a node containing an empty directory entry. | |
2332 | ||
2333 | E2fsck could sometimes in rare circumstances leave the indexed flag | |
2334 | set after a small directory was optimized by compressing it instead of | |
2335 | indexing it. (This should never happen in real life, since | |
2336 | directories that small wouldn't have been indexed, but better safe | |
2337 | than sorry.) | |
2338 | ||
2339 | E2fsck now only updates the master superblock in all cases. This | |
2340 | slightly shortens its run time. | |
2341 | ||
2342 | Ext2ed can deal with directory entries of length 0; previously it | |
2343 | would get stuck in an infinite loop. | |
2344 | ||
2345 | Fsck now has support for reiserfs volumes when parsing LABEL= and UUID= | |
2346 | specifiers. (Sourceforge patch #613447) | |
2347 | ||
2348 | Badblocks will now work correctly on read-only devices such as | |
2349 | CD-ROM's. (Sourceforge patch #600451) | |
2350 | ||
5d823a47 | 2351 | Updated and clarified man pages. (Addresses Debian bug #167108) |

c6633059 TT |
2354 | E2fsprogs 1.29 (September 24, 2002) |
2355 | =================================== | |
2356 | ||
2357 | Fixed a bug in e2fsck which could corrupt a directory when optimizing | |
2358 | it (via the -D option) or rebuiliding the hash tree index with a 1 in | |
2359 | 512 probability, due to a fence post error. | |
2360 | ||
2361 | Fixed a bug in the LVM support code which caused LABEL='xxx' not to | |
2362 | work correctly. | |
2363 | ||
2364 | Mke2fs now enables the directory indexing flag by default. (Since | |
2365 | this is a compatible feature flag, it's safe to do so.) | |
2366 | ||
2367 | Tune2fs will support setting the directory indexing feature flag. It | |
2368 | will automatically set up the default hash algorithm and hash seed | |
2369 | fields in the superblock. | |
2370 | ||
2371 | If the bone-headed user enters the root filesystem twice in | |
2372 | /etc/fstab, the -R option which skips the root filesystem will skip | |
2373 | all of them. (Addresses Debian bug #159423). Note! This is not a | |
2374 | precedent for dealing intelligently with any other kind of doubled | |
2375 | entry in /etc/fstab! | |
2376 | ||
2377 | ||
2378 | Programmer's notes: | |
2379 | ------------------- | |
2380 | ||
2381 | Removed perror declaration in lib/et/internal.h. All modern systems | |
2382 | can be expected to define perror() these days. Besides, the lib/et | |
2383 | code wasn't using perror at all anyway. :-) | |
2384 | ||
2385 | ||
b7bad615 TT |
2386 | E2fsprogs 1.28 (August 31, 2002) |
2387 | ================================ | |
2388 | ||
2389 | Add support for the Hashed-Tree Directory Indexing to e2fsck. Support | |
2390 | for setting the htree flag is not included yet, although it can be | |
2391 | manually turned on via the debugfs program. | |
2392 | ||
2393 | Clarified e2fsck error message which is printed when it cannot find | |
2394 | sufficient contiguous block when relcating filesystem metadata. | |
2395 | ||
2396 | Added support for building an EVMS plugin module for ext2/3. This | |
2397 | module is substantially the same as the EVMS module shipping with EVMS | |
2398 | 1.1, with one or two bugfixes. E2fsprogs can also build this plugin | |
2399 | for use with EVMS 1.0 (which did not include the ext2 plugin module), | |
2400 | if the configure --enable-old-evms flag is given. | |
2401 | ||
2402 | Fsck will search through EVMS volumes when trying to resolve | |
2403 | filesystem specifications such as LABEL=xxx or UUID=xxx. | |
2404 | ||
2405 | Added a new utility program, /sbin/findfs, which will return | |
2406 | filesystem specifications such as LABEL=xxx or UUID=xxx, and prints | |
2407 | the device name. | |
2408 | ||
2409 | Update and clarified various man pages. (addresses Debian Bug #145044, | |
2410 | #146437, #131350, #151990, #144621, #141938) | |
2411 | ||
2412 | If there are no filesystems specified on fsck's command line, fsck now | |
2413 | treat that as if the -As options were given. Previously it would | |
2414 | simply do nothing. (Addresses Debian Bug #153102) | |
2415 | ||
2416 | Mke2fs no longer treats a failure to be able to clear the MD signature | |
2417 | at the end of the filesystem as a fatal error. (Addresses Debian Bug | |
2418 | #155007) | |
2419 | ||
2420 | The e2p library functions (which are used by lsattr and chattr) now | |
2421 | double check to make sure the file is a regular file or directory | |
2422 | before attempting to use the ext2 ioctls. Some device drivers | |
2423 | unfortunately respond to the ext2 ioctl's with unknown behaviour. | |
2424 | (Addresses Debian Bug #152029). | |
2425 | ||
2426 | The extended attribute handling has been updated to correspond with | |
2427 | the latest V2 bestbits ACL code. | |
2428 | ||
2429 | Fixed bug in e2fsck which caused it to not clear the dtime field when | |
2430 | processing truncated inodes on the orphan list. This could cause data | |
2431 | loss(!) if a filesystem is rebooted before a truncate has been | |
2432 | committed. | |
2433 | ||
2434 | E2fsck now uses red/black trees in pass1b, which removes some O(n**2) | |
2435 | algorithms. This makes e2fsck much faster in the case of severely | |
2436 | corrupted filesystems where a large number of blocks are claimed by a | |
2437 | large number of inodes. (Thanks to the 2.5 IDE device driver for | |
2438 | inspiring this work.) | |
2439 | ||
2440 | Resize2fs has been significantly sped up when shrinking and expanding | |
2441 | a filesystem by a very small number of blocks (for example, when EVMS | |
2442 | is converting a partition to be an EVMS legacy volume). | |
2443 | ||
2444 | Added a new option to e2fsck, -D, which will optimize or compress all | |
2445 | of the directories in the filesystem. | |
2446 | ||
2447 | E2fsck now catches SIGINT and SIGTERM to make sure it will can | |
2448 | properly clean up and only exit at safe points. Fsck will pass | |
2449 | SIGINT/SIGTERM to its child processes, and wait until they have all | |
2450 | exited before it exits. | |
2451 | ||
2452 | The uuid parsing code in the uuid library now properly complains when | |
2453 | an illegally formated uuid is presented to it. (Addresses Debian bug | |
2454 | #152891) | |
2455 | ||
2456 | Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 | |
2457 | and 2.4.17, since the workaround can cause problems when using a 2.4 | |
2458 | kernel with an old version of glibc built with the 2.2 headers. | |
2459 | ||
2460 | Fixed a bug in mke2fs where it wasn't properly clearing the initial | |
2461 | superblock used by other filesystems. (Addresses Debian bug #147256.) | |
2462 | ||
2463 | Added support for the synchronous directory feature written by Andrew | |
2464 | Morton. | |
2465 | ||
2466 | The debugfs program can delete directories using the rmdir command. | |
2467 | ||
2468 | Add support for 8k and 16k filesystems (for systems with page sizes | |
2469 | that are greater or equal to 8k or 16k, respectively). Note that | |
2470 | these filesystems can not be mounted on x86 systems, or other systems | |
2471 | with only 4k page sizes, due to limitations in the current Linux VM | |
2472 | code. | |
2473 | ||
2474 | Resize2fs requires that the filesystem state be valid and have no | |
2475 | errors; otherwise, e2fsck -f must be run first. (Previously it simply | |
2476 | required that the last fsck time be greater than the last mount time.) | |
2477 | ||
2478 | Configure now defaults the man pages directory to /usr/share/man on | |
2479 | Linux systems. | |
2480 | ||
2481 | E2fsck now offers to truncate inodes which contain too many blocks (so | |
2482 | that i_blocks would overflow. Also fixed handling of large sparse | |
2483 | files. | |
2484 | ||
2485 | E2fsck now more completely checks for symlink validity, including | |
2486 | requiring NULL termination and length checks. | |
2487 | ||
2488 | E2fsck will offer to try forcing a disk write to remap a bad block | |
2489 | after finding a read error when reading a filesystem metadata block. | |
2490 | ||
2491 | Fixed a bug in debugfs which caused the -b and -s options to crash | |
2492 | debugfs, as well as breaking the testb, setb, and clearb functions. | |
2493 | ||
2494 | Added a bmap command to debugfs which calculates the logical to | |
2495 | physical block mapping for a particular inode. | |
2496 | ||
2497 | Fixed a bug in code which checked to see if a device was mounted which | |
2498 | sometimes (rarely) failed in the case of a plain file. | |
2499 | ||
2500 | Fixed a bug in resize2fs where when it reported an error, it would | |
2501 | print a message erroneously indicating that the filesystem had been | |
2502 | resized before it aborted. | |
2503 | ||
2504 | When resizing a plain file which is smaller than the requested size, | |
2505 | resize2fs will attempt to extended the file so that programs like | |
2506 | e2fsck will not complain that the file is too small. | |
2507 | ||
2508 | Resize2fs will print the actual new size of the filesystem when it is | |
2509 | finished resizing. | |
2510 | ||
2511 | Fixed a bug in debugfs where "ls -l" would report incorrectl file type | |
2512 | information on big-endian systems. | |
2513 | ||
2514 | ||
2515 | Programmer's notes: | |
2516 | ------------------- | |
2517 | ||
2518 | Fixed collisions with C++ reserved words. | |
2519 | ||
2520 | Added portability fixes for building e2fsprogs on the HURD and AIX. | |
2521 | ||
2522 | Added the ext2ed program for creation of test cases. (ext2ed has many | |
2523 | limitations and bugs which make it unsuitable for production use.) | |
2524 | ||
2525 | The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new | |
2526 | flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the | |
2527 | name_len field is byte swampped on big-endian machines, since in the | |
2528 | V2 structure, name_len is a char field which is doesn't need to be | |
2529 | byte swapped --- except if an old-style kernel had byte-swapped the | |
2530 | name_len field as part of the V1 structure. | |

2533 | E2fsprogs 1.27 (March 8, 2002) |
2534 | ============================== | |
2535 | ||
2536 | The warning messages for mke2fs now go to standard error. | |
2537 | ||
2538 | Fixed to make sure "make check" runs all of the test programs with | |
2539 | LD_LIBRARY_PATH set, so that we test the libraries in the build tree. | |
2540 | ||
2541 | The mke2fs program checks the boot sector for the BSD disk label, and | |
2542 | avoids erasing it if it is there. | |
2543 | ||
2544 | Fixed a bug in e2fsck which caused it to core dump if the journal | |
2545 | inode was missing when it was supposed to be there. | |
2546 | ||
2547 | E2fsck now prints ranges in pass 5 when printing deltas for the block | |
2548 | and inode bitmaps. | |
afa14ba0 TT |
2549 | |
2550 | Debugfs's "ls -l" command now will print out the file type information | |
2551 | in the directory entry. | |
2552 | ||
2553 | Create man pages and hard links for fsck.ext3 and mkfs.ext3. If | |
2554 | mke2fs is invoked as mkfs.ext3, create the filesystem with a journal. | |
2555 | ||
2556 | Debugfs can now examine the experimental directory indexing | |
2557 | information. | |
2558 | ||
a471ac52 TT |
2559 | Fixed bug in debugfs which caused it to core dump if modify_inode is |
2560 | called without an open filesystem. | |
2561 | ||
2562 | The debugfs lsdel command now runs its output through a pager first. | |
2563 | ||
afa14ba0 TT |
2564 | When installing manual pages, remove the compressed manual pages first. |
2565 | ||
2566 | Synchronized with Debian's packaging information for e2fsprogs-1.26-1. | |
2567 | ||
2568 | Fix the 2.4 resource limitation workaround introduced in 1.26 which | |
2569 | actually broke things on mips32, sparc32, and Alpha platforms. | |
2570 | ||
a471ac52 TT |
2571 | Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made |
2572 | (which is required by the newer libintl libraries). | |
2573 | ||
afa14ba0 TT |
2574 | Programmer's notes: |
2575 | ------------------- | |
2576 | ||
a8e77249 TT |
2577 | Fixed various gcc -Wall complaints. |
2578 | ||
afa14ba0 TT |
2579 | Fixed a few memory leaks in the e2fsck journaling code, and in the |
2580 | ismounted code checking for a swap device. | |
2581 | ||
2582 | Add new inode I/O abstraction interface which exports an inode as | |
2583 | an I/O object. | |
2584 | ||
2585 | Exported ext2_file_flush as a public interface. | |
2586 | ||
2587 | In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer. | |
2588 | ||
2589 | Lots of small random portability fixes to make e2fsprogs build under | |
2590 | AIX --- even without the 5L compatibility toolkit, and even using the | |
2591 | uber-crippled AIX native C compiler. | |
2592 | ||

a5f3f5c1 | 2595 | ================================= |
cd1a79a5 | 2596 | |
446314fc TT |
2597 | Dumpe2fs will keep going now if the bad block inode can't be read. |
2598 | (Previously it stopped with a fatal error.) | |
2599 | ||
2600 | E2fsck will now give an opportunity to run the journal even if the | |
2601 | recovery flag is not set. This is the default behaviour if e2fsck is | |
2602 | using a backup superblock, since the needs_recovery flag will never be | |
2603 | set in the backup superblock copies. | |
2604 | ||
2605 | E2fsck now automatically finds the backup superblock/group descriptors | |
2606 | even when the primary superblock is completely destroyed for 2k and 4k | |
2607 | filesystems. (Previously it just guessed/assumed that we were dealing | |
2608 | with a 1k filesystem in that case, and users had to manually specify | |
2609 | the backup superblock number.) | |
2610 | ||
2611 | Fixed a bug in e2fsck where it dereferences a null pointer when there | |
2612 | is a problem opening a filesystem in preen mode. | |
2613 | ||
2614 | E2fsck now handles external journals correctly; previously it trashed | |
2615 | the external journal device if the journal needed to be replayed. | |
2616 | ||
2617 | Work around ulimit incompatibility problem caused by recent 2.4 | |
2618 | kernels; the unix IO module will automatically try to set any resource | |
2619 | limits to be infinite on startup. | |
2620 | ||
cd1a79a5 TT |
2621 | Fixed a bug in e2fsck where it wasn't allocating a new block or inode |
2622 | bitmap if it wasn't present and the blocksize was 2k or 4k. | |
9c7ec178 | 2623 | (Addresses Debian Bug #116975) |
cd1a79a5 TT |
2624 | |
2625 | E2fsck will check and fix botched ext3 V1 to V2 superblock updates by | |
2626 | clearing the new V2 fields if they do not make sense or if the ext3 | |
2627 | superblock is version 1 superblock. | |
2628 | ||
2629 | E2fsck will automatically relocate the ext3 journal from a visible | |
2630 | file (i.e., /.journal) to an hidden inode if the filesystem has been | |
2631 | opened read/write. This allows the users to add a journal while the | |
2632 | filesystem is mounted, but the next time the system is rebooted, the | |
2633 | journal file will disappear. This avoids problems with backups, | |
2634 | stupid operators with superuser bits, etc. | |
2635 | ||
2636 | Fix a bug in fsck where it would not support a filesystem type of | |
2637 | "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. | |
2638 | ||
a5f3f5c1 TT |
2639 | Fsck now supports fstab entries of the form "ext3,ext2". It will also |
2640 | automatically identify reiserfs filesystems. | |
2641 | ||
2642 | The number of processes spawned by fsck can now be limited using the | |
2643 | FSCK_MAX_INST environment variable. | |
2644 | ||
446314fc TT |
2645 | Fsck now searchs the LVM proc hierarchy to find logical volumes which |
2646 | should be searched for UUID and label information. | |
2647 | ||
cd1a79a5 TT |
2648 | Work around a bug in 2.4.10+ kernels by trying to unset the filesize |
2649 | limit if at all possible, when opening a block device. (The filesize | |
2650 | limit shouldn't be applied against writes to a block device.) | |
2651 | ||
446314fc TT |
2652 | In mke2fs and e2fsck, specifying the -c option twice will now do |
2653 | a read/write test on the disk. Update the man pages to encourage | |
2654 | using the -c option, and to discouraging running badblocks separately, | |
2655 | since users tend to forget to set the blocksize when running | |
2656 | badblocks. | |
2657 | ||
cd1a79a5 TT |
2658 | Mke2fs now automatically clears the immutable attribute on a |
2659 | pre-existing .journal file left over from a previous failed attempt to | |
2660 | add a journal to an alreadyy-mounted filesystem. | |
2661 | ||
2662 | Fixed mke2fs's exit codes to consistently indicate when the mke2fs | |
2663 | operation failed. | |
2664 | ||
446314fc TT |
2665 | Mke2fs now creates the lost+found directory with permissions of 0700, |
2666 | so that files that had previously lived in protected directory are | |
2667 | safe if they get dropped in lost+found and the system administrator | |
2668 | doesn't deal with immediately. (Addresses Debian #bug 118443) | |
2669 | ||
2670 | Mke2fs and e2fsck (and all programs that use the | |
2671 | ext2fs_check_if_mounted function) will now properly identify that a | |
2672 | device is mounted, even in cases where devfs has confused things with | |
2673 | multiple devices names with the same identity, or if a dim-witted | |
2674 | system administrator has done something stupid like creating device | |
2675 | file aliases in their home directory. Also now checks for swap devices | |
2676 | by using /proc/swaps. (Addresses Debian bug #106622) | |
2677 | ||
a5f3f5c1 TT |
2678 | Added a new option (-T) to tune2fs which sets the time a filesystem |
2679 | was last checked. | |
2680 | ||
cd1a79a5 TT |
2681 | Speed up e2image when creating sparse raw image files by optimizing |
2682 | away excess lseek() system calls. | |
2683 | ||
2684 | Fix support of large (> 2GB) files when used as a filesystem in | |
2685 | mke2fs, tune2fs, debugfs, and findsuper. | |
2686 | ||
2687 | Debugfs's stat and icheck commands now properly deals with large (> | |
2688 | 2GB) files. | |
2689 | ||
2690 | Debugfs's set_super_value command now prints out the list of valid | |
2691 | superblock fields which can be set using the command. | |
2692 | ||
446314fc TT |
2693 | Debugfs's rm and kill_file command now updates the superblock free block |
2694 | and inode counts, thus keeping the filesystem consistent. | |
2695 | ||
a5f3f5c1 TT |
2696 | Debugfs's lsdel command now takes an optional argument which allows |
2697 | the user to only see the most recently deleted files. | |
2698 | ||
2699 | A new command (undel) was added to debugfs which automates | |
2700 | undeleting a deleted inode and linking it back to a directory. | |
2701 | ||
2702 | Debugfs's ls command now takes a new option, -d, which lists | |
2703 | deleted directory entries. | |
2704 | ||
2705 | Debugfs's testb, freeb, setb, and find_free_block commands now take an | |
2706 | optional count argument. | |
2707 | ||
cd1a79a5 TT |
2708 | Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will |
2709 | be used to signal that a particular inode should not be eligible for | |
2710 | tail-merging --- this is needed for programs like LILO. | |
2711 | ||
2712 | The findsuper (an unreleased, uninstalled utility program) has been | |
2713 | improved to add extra validity checks and to add a progress meter. | |
2714 | (It is still an unsupported program; the officially supported way to | |
2715 | recover from a trashed partition table is to use gpart; findsuper is | |
2716 | for wizards only. :-) | |
2717 | ||
2718 | Debugfs was fixed to compile with "configure --disable-swapfs". | |
2719 | ||
446314fc | 2720 | Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) |
cd1a79a5 TT |
2721 | |
2722 | Added new translation file for Turkish. | |

2724 | Programmer's notes: |
2725 | ------------------- | |
2726 | ||
2727 | Fix general gcc -Wall complaints. | |
2728 | ||
2729 | E2fsprogs (mostly) works with the dietlibc. | |
2730 | ||
2731 | The programming texinfo file has been expanded to include description | |
2732 | of additional libext2fs functions. (Still not compeltely done, but a | |
2733 | lot of the more important functions have been documented.) | |
2734 | ||
2735 | Added a umask structure to struct_ext2_filsys, which currently only | |
2736 | modifies the behaviour of ext2fs_mkdir(), but if we add any file | |
2737 | creation functions to libext2fs, we should also make sure they respect | |
2738 | the umask setting. | |
2739 | ||
a5f3f5c1 TT |
2740 | The build-rpm script was fixed to be a bit more safe. |
2741 | ||
2742 | The tests' Makefile now has a way of automating test case creation | |
2743 | for e2fsck, using "make testnew". | |
2744 | ||
2745 | Created a new function, ext2fs_dir_iterate2 which passes more | |
2746 | information to the callback function (identical to the one used by | |
2747 | ext2fs_dblist_dir_iterate). The directory iterator functions take a | |
2748 | new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted | |
2749 | directory entries. If the directory entry is deleted, the callback | |
2750 | function will be called with the entry paraemter set to | |
2751 | DIRENT_DELETED_FILE. | |
2752 | ||
2753 | Added new functions, ext2fs_inode_alloc_stats and | |
2754 | ext2fs_block_alloc_stats, which takes updates block/inode allocation | |
2755 | statistics in the bitmaps, block group descriptors, and superblock | |
2756 | when inodes or blocks are allocated or deallocated. | |

2759 | E2fsprogs 1.25 (September 20, 2001) |
2760 | =================================== | |
2761 | ||
2762 | This is primarily a bug-fix release; no new features were added, but | |
2763 | there are a number of embarassing bug fixes and cleanups applied. | |
2764 | ||
2765 | Fix a bug mke2fs which causes stack garbage to be written to disk when | |
2766 | zapping disk sectors. (This bug could cause mke2fs to core dump for | |
2767 | some kernels, I suspect with security enhancement patches.) | |
2768 | ||
2769 | Remove unneeded #include of <linux/config.h> which was breaking | |
2770 | building e2fsprogs on the Hurd. (Addresses Debian bug #112414.) | |
2771 | ||
2772 | Updated tune2fs man page to reflect the fact that adding or removing a | |
2773 | journal doesn't require running e2fsck. | |
2774 | ||
2775 | Remove use of AC_REQUIRE from autoconf which had been used to prevent | |
2776 | AC_CANONICAL_HOST from being called twice; unfortunately this causes | |
2777 | recent autoconf to bomb out since they don't allow AC_REQUIRE to be | |
2778 | used outside of autoconf macros. Fortunately, it doesn't seem to be | |
2779 | necessary any more, anyway. | |
2780 | ||
2781 | E2fsck will now not fall back to an alternate superblock if the user | |
2782 | specifies the superblock location explicitly on the command-line. | |
2783 | This allows easier recovery from a situation where the primary | |
2784 | superblock and block groups are slightly corrupted, but the backup | |
2785 | superblocks are completely broken. | |
2786 | ||
2787 | Fix problem which caused compile_et and mk_cmds to blow up if | |
2788 | e2fsprogs was in a directory with a pathname that contained spaces. | |
2789 | ||
2790 | We are now more paranoid about checking the entry in /etc/mtab to make | |
2791 | sure the filesystem is really mounted, since some broken distributions | |
2792 | (read: Slackware) don't initialize /etc/mtab before checking non-root | |
2793 | filesystems. (Slackware also doesn't check the root filesystem | |
2794 | separately, and reboot if the root filesystem had changes applied to | |
2795 | it, which is dangerous and broken, but there's nothing I can do about | |
2796 | that.) | |
2797 | ||
2798 | Make UUID library C++ friendly by adding appropriate extern "C" | |
2799 | declarations and using const in the function declarations. | |
2800 | ||
2801 | Fix up the com_err texinfo file so that it can product a valid info | |
2802 | file (previously, it could only be used to generate paper | |
2803 | documentation using texinfo.tex). | |
2804 | ||
2805 | ||
fb70775b TT |
2806 | E2fsprogs 1.24a (September 2, 2001) |
2807 | =================================== | |
2808 | ||
2809 | Fix brown-paper bug in mke2fs which caused it to segfault when | |
2810 | printing the version string. | |
2811 | ||
2812 | ||
109624a1 TT |
2813 | E2fsprogs 1.24 (August 30, 2001) |
2814 | ================================ | |
2815 | ||
2816 | Revert the BLKGETSIZE64 support, since for some distributions, this | |
2817 | ioctl has been used by an unofficial kernel patch to update the last | |
2818 | sector on the disk, and this was causing disk corruption problems as a | |
2819 | result. | |
2820 | ||
2821 | Mke2fs is now more careful about zapping swap space signatures and | |
2822 | other filesystem/raid superblock magic values so that programs like | |
2823 | mount who try to use hueristics to determine the filesystem type of a | |
2824 | partition are less likely to be confused. | |
2825 | ||
2826 | E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a | |
2827 | regular file (since Andreas Dilger's on-line resizing tools will set | |
2828 | its mode bits). | |
2829 | ||
2830 | Fixed some minor texinfo, man pages nits for spelling errors, | |
2831 | texinfo warnings, etc. (Addresses Debian bug #110621.) | |
2832 | ||
2833 | E2fsprogs program no longer print the filesystem version number | |
2834 | (i.e. 0.5b), since it only confuses people and doesn't serve any real | |
2835 | purpose. | |
2836 | ||
2837 | E2fsck will once again compile under libc5, since it will supply its | |
2838 | own version of strnlen if necesssary. | |
2839 | ||
2840 | mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers | |
2841 | when specifying the external journal device. tune2fs will also search | |
2842 | devices looking for the externla journal debice when removing. | |
2843 | ||
2844 | E2fsprogs 1.23 (August 15, 2001) | |
2845 | ================================ | |
d1ef5c34 TT |
2846 | |
2847 | Add initial support for extended attributes (EA); e2fsck will | |
6c0a0417 TT |
2848 | correctly handle a filesystem with EA's and check the EA blocks for |
2849 | corruptions. | |
2850 | ||
d494bba8 TT |
2851 | E2fsck's symlink sanity checking has been cleaned up. It now checks |
2852 | the i_size value of fast symlinks, and checks for immutable flags | |
2853 | being set of symlinks, etc. | |
2854 | ||
c4ac9e14 TT |
2855 | E2fsck now offers to clear inodes which are special files that have a |
2856 | non-zero i_blocks or i_size field. (The i_size field check was in the | |
2857 | previous version of the code, but due to a bug it didn't offer to | |
2858 | clear the inode unless i_size and i_size_high were both non-zero.) | |
2859 | ||
d494bba8 TT |
2860 | E2image can now create "raw" image files, which only contain the |
2861 | filesystem metadata placed in a spare file so that e2fsck, dumpe2fs, | |
2862 | debugfs, etc., can be run directly on the raw image file. | |
bf16d106 TT |
2863 | |
2864 | Add support for the 64-bit block device patches. | |
2865 | ||
2866 | Fixed bugs in creating external journals with a 1k blocksize. | |
2867 | ||
d494bba8 TT |
2868 | Add initial support for external journals (so long as the external |
2869 | journal only supports a single filesystem) in e2fsck. | |
2870 | ||
2871 | Remove requirement for needing to run fsck on a filesystem after | |
2872 | removing a journal (either internal or external). | |
2873 | ||
bf16d106 | 2874 | The man pages now document how to create and manage external journals. |
d1ef5c34 TT |
2875 | |
2876 | Speed up the check of an ext3 filesystems by avoiding a needless flush | |
2877 | of all of the superblock and block group descriptors. | |
2878 | ||
d494bba8 TT |
2879 | Speed up creating an internal journal using tune2fs in the case where |
2880 | the filesystem has a lot blocks already allocated. | |
2881 | ||
c4ac9e14 TT |
2882 | Tune2fs has been fixed to make sure that only error messages go to |
2883 | stderr, and normal message go to stdout. (Addresses Debian bug #108555) | |
2884 | ||
d494bba8 | 2885 | Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will |
c4ac9e14 | 2886 | now not set the sparse_super feature. (Addresses Debian bug #108165) |
d494bba8 | 2887 | |
d1ef5c34 TT |
2888 | Add support in fsck for the filesystem type "auto". |
2889 | ||
c4ac9e14 TT |
2890 | Fsck -A will not try to interpret device names for filesystems which |
2891 | have a pass number is 0. (Addresses Debian bug #106696). | |
2892 | ||
2893 | Fsck prints a warning message if now valid filesystems are passed to | |
2894 | it. (Addresses Debian Bug #107458.) | |
2895 | ||
9249d980 TT |
2896 | E2fsck now gives an explicit warning if there filesystem still has |
2897 | errors at the end of the run. (Addresses Debian bug #104502) | |
2898 | ||
d494bba8 | 2899 | E2fsck will set the EXT2_ERROR_FS flag if the journal superblock |
c4ac9e14 TT |
2900 | reflects an error. E2fsck will also not run the orphan list if the |
2901 | filesystem contains errors, since the orphan list might be corrupted. | |
d494bba8 TT |
2902 | |
2903 | E2fsck now prints the number of large files when given the -v option. | |
2904 | ||
2905 | Fixed minor memory leaks in e2fsck. | |
bf16d106 | 2906 | |
c4ac9e14 | 2907 | Some minor man pages updates. (Addresses Debian bug #30833, #108174) |
9249d980 | 2908 | |
d1ef5c34 | 2909 | |
19d6b54b TT |
2910 | E2fsprogs 1.22 (June 22, 2001) |
2911 | ============================== | |
2912 | ||
2913 | Fixed a bug in e2fsck's handling of orphan inodes which are special | |
2914 | files (i.e., block/character device files, named FIFO's, etc.). | |
2915 | ||
2916 | Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused | |
2917 | tune2fs to fail at adding a journal to a mounted filesystem. | |
2918 | ||
2919 | Fixed a few big-endian bugs in e2fsprogs | |
2920 | * The directory block functions were accidentally reporting | |
2921 | some directories as corrupted when they weren't. | |
2922 | * If e2fsprogs is compiled --disable-swapfs, the C language | |
2923 | equivalents weren't being included for big-endian platforms. | |
2924 | (Fixes Debian bug #101686). | |
2925 | ||
2926 | Fixed a Hurd compilation problem. (Addresses Debian bug #101361) | |
2927 | ||
2928 | Programmer's notes: | |
2929 | ------------------- | |
2930 | ||
2931 | Use platform independent method of defining the BLKFLSBUF and FDFLUSH | |
2932 | ioctls, and allow them to be defined for non-i386 platforms. | |
2933 | ||
2934 | The uuid.h header file is now protected against multiple inclusions. | |
2935 | ||
2936 | E2fsprogs is now being developed using BitKeeper. Changed the test | |
2937 | scripts to deal with BK's stripping CR characgters from text files, | |
2938 | and changed the top-level Makefile.in to avoid including BitKeeper | |
2939 | files when generating the source tarball. | |
2940 | ||
2941 | ||
b90b826b TT |
2942 | E2fsprogs 1.21 (June 15, 2001) |
2943 | ============================== | |
2944 | ||
2945 | Added new configure flags which allow a subset e2fsprogs to be built; | |
2946 | this is most useful for boot floopies, since the resulting shared | |
2947 | libraries and programs are slimmed down by removing features that | |
2948 | aren't necessary for a boot floppy. The new flags that were added | |
2949 | are: --disable-swapfs, which removes support for byte swapping old | |
2950 | legacy PPC/68k filesystems, --disable-debugfs, which removes support | |
2951 | for debugfs from the libext2fs library, --disable-imager, which | |
2952 | removes support for the e2image program, and --disable-resizer, which | |
2953 | removes support for resize2fs. | |
2954 | ||
2955 | E2fsck now prints the number of mounts or days elapsed since the last | |
2956 | check when e2fsck is forced to check an otherwise clean filesystem. | |
2957 | ||
2958 | Tune2fs now prints an informative message about how often a filesystem | |
2959 | will be checked when adding a journal to the filesystem, to remind the | |
2960 | user that he/she may want to adjust those parameters using tune2fs | |
2961 | -c/-i. | |
2962 | ||
2963 | Worked around hurd brain-damage which causes e2fsck to sometimes | |
2964 | believe a filesystem is the root filesystem based on device numbers | |
2965 | (since Hurd doesn't have dev_t's, which is arguably a POSIX.1 | |
2966 | violation). | |
2967 | ||
2968 | Fixed a bug introduced in 1.20 which caused e2fsck to abort with an | |
2969 | erroneous error with the -F option was specified. | |
2970 | ||
2971 | Fixed a ext3 recovery bug in the revoke handling; synchronized with | |
c05b5521 TT |
2972 | ext3 0.7a. |
2973 | ||
767de097 TT |
2974 | Fixed two bugs in e2fsck's handling of dup block handling, dealing |
2975 | with relatively uncommon edge cases: a directory with an indirect | |
2976 | block which is claimed by another file, and when the last inode in the | |
2977 | filesystem has blocks claimed by another file. | |
2978 | ||
5a9c036b TT |
2979 | E2fsck now checks to see if the i_size field of a fast symlink is too |
2980 | big, and offers to clear the symlink if so. | |
2981 | ||
2982 | E2fsck now checks to see if i_size_high of special files is non-zero, | |
2983 | and offers to clear i_size_high. | |
2984 | ||
767de097 TT |
2985 | Fix e2fsck's handling of incompatible journal flags so that the user |
2986 | has chance to abort, and then has the option to clear out the journal | |
e333845b | 2987 | entirely. (Addresses Debian bug #98527.) |
767de097 | 2988 | |
b90b826b TT |
2989 | Fixed a bug in fsck which could cause it to core dump if a mix of |
2990 | standard and non-standard device names are used in /etc/fstab. | |
2991 | (Debian bug #100559) | |
2992 | ||
c05b5521 TT |
2993 | Fixed a bug in debugfs which caused read errors when copying a file to |
2994 | not be noticed. | |
2995 | ||
b90b826b TT |
2996 | The debugfs set_super_value command can now modify the s_lastcheck field. |
2997 | ||
c05b5521 TT |
2998 | Fixed a bug in lsattr and chattr which was accidentally introduced in |
2999 | 1.20 to support > 2GB files; both lsattr and chattr wasn't reading | |
3000 | directories correctly because the change modified the layout of struct | |
3001 | dirent to be incompatible with the libe2p shared library. | |
3002 | ||
b90b826b TT |
3003 | Cleaned up the mke2fs manual page and included a discussion about why |
3004 | it's good to periodically check the filesystem even when journaling is | |
3005 | enabled. | |
3006 | ||
767de097 TT |
3007 | Programmer's notes: |
3008 | ------------------- | |
3009 | ||
3010 | Fix general gcc -Wall complaints. | |
3011 | ||
3012 | The types needed by the ext2 header files are now provided by | |
3013 | lib/ext2fs/ext2_types.h, instead of include/asm/types.h. | |
3014 | ||
c05b5521 | 3015 | Integers are now preferred to longs when trying to find a 32-bit type |
b90b826b TT |
3016 | in ext2_types.h. Also, if linux/types.h has already been defined, |
3017 | don't try to redefine the types. | |
c05b5521 | 3018 | |
767de097 TT |
3019 | Fixed make depend script so that it automatically corrects the |
3020 | pathname cleanups performed by make -M, so I don't have to fix them up | |
3021 | by hand. | |
3022 | ||
3023 | Fixed the d_loaddump test case to be more robust, and not depend on | |
3024 | bash'isms. | |
3025 | ||
3026 | Removed debugfs's dependence on pread(), which was accidentally | |
3027 | intrudced in e2fsprogs 1.20 | |
3028 | ||
c05b5521 TT |
3029 | Fixed a performance bug in the libext2fs's icount routine; the size |
3030 | estimate of the icount array was incorrectly being calculated. | |
3031 | ||
b90b826b TT |
3032 | Removed use of the badblocks compatibility functions in the e2fsprogs |
3033 | programs. | |
3034 | ||
3035 | Added paranoia code which protects against strange cases where /etc | |
3036 | isn't on the root filesystem, or if /etc/mtab doesn't exist. | |
3037 | ||
3038 | The header file ext2_types.h is now installed. | |
3039 | ||
3040 | Autoconf is used to determine when we are on big-endian machines, | |
3041 | instead of doing run-time tests, to save a few bytes of code. | |
3042 | ||
3043 | The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap | |
3044 | functions are no longer inline functions, which saves space and | |
3045 | doesn't really cost any real performance. | |
3046 | ||
3047 | The ext2fs library no longer depends on the e2p library. (What need | |
3048 | there was of it --- namely, fsetflags, was coded in-line). | |
3049 | ||
3050 | Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even | |
3051 | when the user is stupid and tries compiling the package using "make | |
3052 | install" as root. | |
3053 | ||
3054 | Miscellaneous code cleanups: | |
3055 | * Added missing files from Makefile.in's SRCS file, so that | |
3056 | their dependencies would be properly calculated. | |
3057 | * Removed redundant code | |
3058 | * Fixed comments in code | |
3059 | * Removed no-longer unneeded argsused #pragma. | |
c05b5521 | 3060 | |
767de097 | 3061 | |
5a009bb9 | 3062 | E2fsprogs 1.20 (May 20, 2001) |
31d1d0c8 | 3063 | ============================= |
5570a65a | 3064 | |
31d1d0c8 TT |
3065 | Add support for replaying the ext3 journal purely in user mode, |
3066 | including handling the orphaned inode list. Used code contributed by | |
3067 | Andreas Dilger, with bug fixes and the orphaned inode handling done | |
3068 | by Theodore Ts'o. | |
3069 | ||
3070 | The mke2fs and tune2fs programs can create or modify a filesystem to | |
3071 | include an ext3 journal. Tune2fs also can be used to remove an ext3 | |
3072 | journal from a filesystem. | |
5570a65a TT |
3073 | |
3074 | E2fsck will now check for the existence of a linked list of orphan | |
3075 | inodes in the superblock, and clear those inodes before starting the | |
3076 | rest of the filesystem check (but after the journal playback). | |
3077 | ||
31d1d0c8 TT |
3078 | E2fsck now validates the file descriptor passed to the -C option, |
3079 | which saves against the completion bar getting written to an | |
3080 | unexpected location, such as the disk being checked. (Debian | |
3081 | bug/wishlist #55220) | |
3082 | ||
3083 | E2fsck will now bump the filesystem revision number from zero to one | |
3084 | if any of the compatibility bits are set. | |
3085 | ||
3086 | Fixed a bug where a badly corrupted directory on a big endian system | |
3087 | could cause e2fsck to die with a bus error. The | |
3088 | ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in | |
3089 | the ext2 library now does alignment sanity checks on the rec_len field | |
3090 | of the directory entry before using it. | |
3091 | ||
3092 | The ext2 library has been enhanced to make tune2fs safe to run on | |
3093 | mounted filesystems. (Users could usually get away with using tune2fs | |
3094 | on mounted filesystems before, but with the advent of ext3 and | |
3095 | journaling, it became important to make tune2fs was *really* safe for | |
3096 | use even when the filesystem being modified is mounted.) E2label is | |
3097 | now implemented by tune2fs using an argv[0] dispatch, so that e2label | |
3098 | is also now safe for use on mounted filesystems. | |
3099 | ||
3100 | Added a new program, e2image, which creates a backup of critical ext2 | |
3101 | filesystem data structures. The generated image file can be examined | |
3102 | using dumpe2fs and debugfs. In the future, e2fsck will be able to use | |
3103 | the image file to help recover very badly damaged filesystems. | |
3104 | ||
3105 | Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files | |
3106 | no longer cause e2fsck to bomb out. Also treat files > 2GB as being | |
3107 | large file when deciding whether or not the filesystem has large files. | |
3108 | ||
3109 | Fixed lsattr and chattr so that they work correctly on large files. | |
3110 | (Fixes Debian bug #72690.) | |
3111 | ||
3112 | Removed limitation in get_device_size() which imposed a one terrabyte | |
3113 | filesystem limitation. (Most 2.2 kernels still have a signed int | |
3114 | problem which cause 1 TB block device limitation. Fortunately, the | |
3115 | kernel patches to fix this are much easier than fixing the 2TB | |
3116 | limitation in the kernel. :-) | |
3117 | ||
3118 | A max_mount_count of zero is now treated as if no mount count were | |
3119 | set. (Previously, no mount count was indicated by using -1, and a | |
3120 | mount count of zero caused e2fsck to always be run.) | |
3121 | ||
77648565 | 3122 | Mke2fs supports two new filesystem types largefile and largefile4. |
31d1d0c8 TT |
3123 | |
3124 | Mke2fs now adds some randomness in s_max_mount_count so that multiple | |
3125 | filesystems won't be all checked at the same time under normal | |
3126 | operations. | |
3127 | ||
5570a65a TT |
3128 | Fixed bug in the progress bar printing code which could cause e2fsck |
3129 | to core dump on an illegal filesystem. | |
3130 | ||
31d1d0c8 TT |
3131 | Fixed bug in fsck which could allow more than one instance of e2fsck |
3132 | to be printing a progress bar. (Debian bug #65267) | |
3133 | ||
5570a65a TT |
3134 | Fsck using a UUID or a LABEL specifier will work even if devfs is |
3135 | compiled into the kernel and not mounted. If the pathnames in | |
3136 | /proc/partitions are incorrect, fsck will search /dev for the correct | |
3137 | device (using the new ext2fs_find_block_device library function). | |
3138 | Fsck now also checks the RAID devices first so that they are properly | |
31d1d0c8 TT |
3139 | found when they are in use. Support has also been added to support |
3140 | additional IDE disks and the DAC 960 device names. (Debian bug #94159) | |
3141 | ||
3142 | Fixed a bug in fsck which caused it not deal properly with 16 | |
3143 | byte long filesystem labels. | |
5570a65a | 3144 | |
5a009bb9 TT |
3145 | Fsck's -t option has been made a lot more flexible. The semantics for |
3146 | what happens if a comma-separated list to fsck has been regularized, | |
3147 | and it is now possible to filter what filesystems will get checked | |
3148 | based what is in the filesystem's fstab entry's option field. (Debian | |
3149 | bug #89483.) | |
3150 | ||
5570a65a TT |
3151 | The dumpe2fs program can now print out the group description |
3152 | information in hex, and also prints the location of the superblock and | |
3153 | block group descriptor for those block groups that have them. | |
3154 | ||
3155 | Mke2fs now clears the ext2 superblock before it starts creating a | |
3156 | filesystem, so that the superblock magic number is only written if the | |
3157 | filesystem creation process successfully completes. | |
3158 | ||
3159 | The debugfs program's stat command now pretty-prints the blocks used | |
3160 | by an inode so that it's more compact and informative. | |
3161 | ||
3162 | The debugfs stats command now uses the same libe2p code (which is used | |
3163 | by dumpe2fs) to print the superblock header information. This is more | |
3164 | complete, and it avoids a bit of code duplication. | |
3165 | ||
3166 | Added a new debugfs command, set_super_value (ssv) which allows the | |
3167 | user to set arbitrary superblock fields. | |
3168 | ||
31d1d0c8 TT |
3169 | Debugfs was extended to support inode numbers in hex (by prefixing |
3170 | them with 0x), and so that modify_inode can set the inode generation | |
3171 | number. Also, there is now a new function command called logdump | |
3172 | which will dump an ext3 journal. | |
3173 | ||
3174 | Fixed a bug in debugfs so that quitting out of the pager doesn't kill | |
3175 | debugfs. | |
3176 | ||
3177 | Debugfs's dump command now stops immediately upon reporting a disk | |
3178 | read error. (Fixed a bug in ext2fs_file_read library routine which | |
3179 | caused debugfs not to stop.) (Debian bug #79163) | |
3180 | ||
3181 | On systems with /proc/mounts (mainly Linux systems), /proc/mounts is | |
3182 | checked before /etc/mtab is used, since /proc/mounts is more likely to | |
3183 | be accurate. | |
3184 | ||
3185 | Added portability fixes for Solaris and Linux/ia64. | |
3186 | ||
3187 | Various manual pages were clarified and cleaned up. (Fixed debian | |
3188 | bugs #63442, #67446, and #87216) | |
3189 | ||
5570a65a TT |
3190 | |
3191 | Programmer's notes: | |
3192 | ------------------- | |
3193 | ||
3194 | The e2fsck message printer now supports %Iu and %Ig, which will print | |
3195 | out the inode's user and group owners, respectively. | |
3196 | ||
31d1d0c8 TT |
3197 | E2fsprogs now includes its own version of include/linux/ext2_fs.h, so |
3198 | that no longer dependent on the system having the correct version of | |
3199 | the kernel header files. | |
3200 | ||
5570a65a TT |
3201 | Added a new function to libext2, ext2fs_find_block_device(), which |
3202 | searches the system (i.e., /dev, /devfs, /devices) for a pathname to a | |
3203 | device given its device number. | |
3204 | ||
31d1d0c8 TT |
3205 | Added a new function to libext2, ext2fs_sync_device, which centralizes |
3206 | all of the places which might try to use the BLKFLSBUF or FDFLUSH | |
3207 | ioctls (and usually failing to define them since the system header | |
3208 | files don't usually do this for us, and we're trying to avoid usage of | |
3209 | kernel include files now). | |
3210 | ||
5570a65a TT |
3211 | Added new utility programs in tests/progs: random_exercise and |
3212 | hold_inode. They aren't built by default; they're useful for | |
3213 | exercising ext3 filesystem code. | |
3214 | ||
31d1d0c8 TT |
3215 | Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes |
3216 | the filesystem close functions to only update the superblock, and to | |
3217 | not touch the block group descriptors. Needed by tune2fs when | |
3218 | modifying a mounted filesystem. | |
3219 | ||
3220 | Got rid of struct ext2fs_sb and replaced it with the standard struct | |
3221 | ext2_super_block from include/linux/ext2_fs.h. Note: this may break | |
3222 | source (but not binary) compatibility of some users of the ext2 | |
3223 | library. Those applications should just simply do a global search and | |
7d614e3d TT |
3224 | replace of struct ext2fs_sb with struct ext2_super_block, and include |
3225 | the new header file <ext2fs/ext2_fs.h> which defines it. | |
31d1d0c8 TT |
3226 | |
3227 | The ino_t type has been renamed ext2_ino_t to protect applications | |
3228 | that attempt to compile -D_FILE_OFFSET_BITS=64, since this | |
3229 | inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an | |
3230 | unexpected ABI change. | |
3231 | ||
3232 | The Makefiles have been reworked so that "make check" can be run from | |
3233 | the top-level Makefile. | |
3234 | ||
3235 | Fix general gcc -Wall complaints and removed dead code. | |
3236 | ||
3237 | Remove use of NOARGS, because we assume everyone does ANSI C these | |
3238 | days. | |
3239 | ||
3240 | Added build-rpm script from sct. | |
3241 | ||
3242 | New functions ext2fs_image_{inode,super,bitmap}_{read,write} added | |
3243 | to support e2image. | |
3244 | ||
3245 | New function ext2fs_flush_icache which must be called if the | |
3246 | application program modifies the inode table blocks without going | |
3247 | through ext2fs_write_inode() interface. | |
3248 | ||
3249 | New ext2fs_check_mount_point() function, which will return the mount | |
3250 | point of a device if mounted. | |
3251 | ||
3252 | The io_channel abstraction now has an optional interface, | |
3253 | io_channel_write_range, which allows specific byte ranges to be | |
3254 | written. | |
3255 | ||
3256 | The unix_io IO channel now supports write-through caching, so that | |
3257 | journal creation is more efficient. | |
3258 | ||
3259 | Added x86 assembly language routines to support byte swapping, to | |
3260 | reduce executable size. | |
3261 | ||
3262 | Fixed bug in the utility program subst so that it's possible to | |
3263 | replace a substitution variable with a zero-length string. | |
3264 | ||
3265 | Fixed numbering e2fsck pass1 problem numbers; an extra zero had | |
3266 | slipped into some of the problem number. | |

3268 | E2fsprogs 1.19 (July 13, 2000) |
3269 | ============================== | |
ab146766 TT |
3270 | |
3271 | Release the resize2fs program since the timeout before it could | |
006ea71e | 3272 | be released under the GPL has finally expired. |
ab146766 TT |
3273 | |
3274 | Add experimental support needed for the ext2 compression patches. | |
3275 | This requires compiling e2fsprogs with the --enable-compression flag | |
3276 | to the configure script. | |
3277 | ||
3278 | Added ext3 journalling support. E2fsck will run the journal (if | |
3279 | necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is | |
3280 | installed as a symlink to e2fsck. Fsck has been taught about ext3, | |
3281 | and treats it the same as ext2 in terms of the progress bar logic. | |
3282 | Dumpe2fs will display the superblock journaling information if the | |
3283 | filesystem has a journal. The ext2 library will now permit opening an | |
3284 | ext3 filesystem with the recovery flag set. This is necessary for | |
3285 | on-line dump's to work correctly, but there may be issues with this | |
3286 | working well since ext3 is much less agressive about syncing blocks to | |
3287 | the filesystem, since they're safe on the journal. | |
3288 | ||
3289 | Tune2fs and e2fsck have been changed to allow the mount_count check to | |
3290 | be disabled by setting max_mount_count to -1. (This was already | |
3291 | supported by the kernel.) | |
3292 | ||
3293 | Create a symbolic link for fsck.ext3, since the e2fsprogs utilities | |
3294 | are used for ext3 as well. | |
3295 | ||
3296 | Added internationalization support for e2fsprogs; must be enabled | |
3297 | by passing --enable-nls to configure. | |
3298 | ||
3299 | Always use the provided ext2fs header files to insulate ourselves from | |
3300 | kernel version changes. Which include files are used by e2fsprogs | |
3301 | have also been cleaned up to improve portability. | |
3302 | ||
3303 | Limit the number of times that e2fsck updates the progress bar so that | |
3304 | people who are booting using a 9600 baud console don't get swampped by | |
3305 | too many updates. | |
3306 | ||
3307 | Improved the loop detection algorithm in e2sck's pass #3 so that it is | |
3308 | much, much faster for large filesystems with a large number of | |
3309 | directories. | |
3310 | ||
3311 | The memory footprint for e2fsck is now slightly smaller than before. | |
3312 | ||
3313 | E2fsck now checks if special devices have a non-zero size, and offers | |
3314 | to clear the size field if it finds such an inode. | |
3315 | ||
3316 | E2fsck now checks if special devices have the append-only flag set, | |
3317 | and offers to clear the inode. | |
3318 | ||
3319 | E2fsck now properly handles some "should never fail" cases during a | |
3320 | bitmap copy in pass5. | |
3321 | ||
3322 | E2fsck now properly prints control characters in filenames as ^A .. ^Z. | |
3323 | ||
31d1d0c8 TT |
3324 | E2fsck now calculates the correct location of the backup superblock in |
3325 | the case of filesystem blocksizes > 1k. | |
3326 | ||
3327 | Fixed a bug in e2fsck's calculation of the number of inodes_per_block | |
3328 | which normally didn't cause problems under most filesystem parameters, | |
3329 | but could cause a valid superblock to be rejected in extreme cases. | |
3330 | Other checks for validating superblock values were made more | |
3331 | stringent. | |
3332 | ||
ab146766 TT |
3333 | Added non-destructive write testing to the badblocks program, courtesy |
3334 | of David Beattie. The badblocks also now has an option to input the | |
3335 | current set of bad blocks, so that known bad blocks are skipped to | |
3336 | speed up the badblocks test. There is also a persistent rescan | |
006ea71e TT |
3337 | feature which causes badblocks to run until it has completed some |
3338 | number of passes without discovering any new bad blocks. | |
ab146766 TT |
3339 | |
3340 | Badblocks now checks to see if the device is mounted and refuses to do | |
3341 | the tests involving writing to the device if it is mounted. Also, | |
3342 | badblocks now allows the number of blocks to be checked to be | |
3343 | defaulted to the size of the partition. | |
3344 | ||
3345 | Fixed a bug in fsck which didn't allow non-root users to be able to | |
3346 | check filesystems if there were any LABEL= or UUID= entries in | |
3347 | /etc/fstab. | |
3348 | ||
3349 | The Hurd doesn't support the filetype filesystem feature. The mke2fs | |
3350 | program now makes sure that for the Hurd, the filestype feature is | |
3351 | turned off. E2fsck will check to see if the filetype feature is | |
3352 | turned on for Hurd filesystems, and offer to turn off the feature. | |
3353 | ||
3354 | Mke2fs now has a safety check to make sure the number of blocks do not | |
3355 | exceed 32 bits even on a 64 bit platform. | |
3356 | ||
3357 | Really fixed a bug in fsck to allow "fsck -As" to run interactive | |
3358 | fsck's. (For those people who like to do interactive fsck's in the | |
3359 | /etc/rc scripts!?!) | |
3360 | ||
3361 | Debugfs has a few new features: the rdump command, which will do a | |
3362 | recursive dump of a directory and all of its contents, and the lcd | |
3363 | command which does a local chdir (much like the ftp command of the | |
3364 | same name). In addition, the debugfs program and the open_filesystem | |
3365 | command now takes three new options: -b and -s, which allows the | |
3366 | blocksize and superblock location to be specified, and the -c option | |
3367 | which is used in catastrophic situations where the block group | |
3368 | descriptors are corrupt. If the -c option is specified, debugfs will | |
3369 | skip trying to read in the block and inode bitmaps. | |
3370 | ||
3371 | Debufs's lsdel command was fixed to handle bad blocks in the inode | |
3372 | table. | |
3373 | ||
3374 | A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use | |
3375 | 4 digit years. | |
3376 | ||
3377 | General improvements in error messages | |
3378 | ||
3379 | - Mke2fs prints a sane error message if the partition size is zero | |
3380 | (usually because the partition table wasn't reread by the | |
3381 | kernel due to the partition being busy), instead of "invalid | |
3382 | argument passed to ext2 library while initializing superblock". | |
3383 | ||
3384 | - Fsck now prints more self-explanatory message if an invalid UUID= | |
3385 | or LABEL= specification is passed to it. | |
3386 | ||
3387 | UUID library changed to use the LGPL. | |
3388 | ||
3389 | Fixed a bug in the UUID library where very rapid calls to the | |
3390 | time-based UUID generator could cause duplicate UUID's to be returned. | |
3391 | This was not a problem for e2fsprogs, but it could be a problem for | |
3392 | other users of the library. | |
3393 | ||
3394 | Make the UUID library more robust in the face of missing or an | |
3395 | improper /dev/urandom or /dev/random files. | |
3396 | ||
3397 | Added some random portability fixes for Solaris. | |
3398 | ||
3399 | Some minor man page updates. | |
3400 | ||
3401 | Fixed a memory leak in the ss library. | |
3402 | ||
3403 | ||
3404 | Programmer's notes: | |
3405 | ------------------- | |
3406 | ||
3407 | We now try to use lseek64 and open64 from the LFS if possible. | |
3408 | ||
3409 | The 3rd parameter in e2p's print_flags is now a flags word, instead of | |
3410 | a boolean option. | |
3411 | ||
3412 | The mark and unmark bitmap functions now return the previous state of | |
3413 | the bit that was being changed, which is useful for some speed | |
3414 | optimizations. | |
3415 | ||
3416 | The following functions have been added to enhance the badblocks list | |
3417 | handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and | |
3418 | ext2fs_badblocks_equal. | |
3419 | ||
3420 | The ext2 header files now have the latest journalling fields to the | |
3421 | superblock. | |
3422 | ||
3423 | The ext2fs_mkdir function in libext2fs now properly backs out of error | |
3424 | conditions robustly. | |
3425 | ||
3426 | Cleaned up makefiles: | |
3427 | - to cleanly compile with the -j flag. | |
3428 | - so distclean removes all generated files. | |
3429 | - so in case of an error while installing header files, the make aborts. | |
3430 | ||
3431 | Fix test_script so that it works correctly when compiling in the | |
3432 | source directory. | |
3433 | ||
31d1d0c8 TT |
3434 | The random UUID generation routine has been made slightly better in |
3435 | the case where /dev/random doesn't exist. (Use of randomly-based UUID | |
3436 | is still not recommended if /dev/random doesn't exist, however; it's | |
3437 | better to use the time/ethernet MAC address UUID in this case.) | |
ab146766 TT |
3438 | |
3439 | Clean up the build process so it's more friendly in case of missing | |
3440 | directories. | |
3441 | ||
3442 | The ext2fs header file can now be #include'd into C++ programs. | |
3443 | ||
3444 | The e2p.h header file is now installed. | |
3445 | ||
3446 | Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. | |
3447 | ||
3448 | ||
3449 | ||
24ded091 TT |
3450 | E2fsprogs 1.18 (November 10, 1999) |
3451 | ================================== | |
3452 | ||
3453 | Fix a core dumping bug in e2fsck if an imagic inode is present or | |
3454 | (more rarely) if the filesystem is badly corrupted enough that e2fsck | |
3455 | has to restart pass 1 processing. E2fsck now closes the filesystem | |
3456 | before freeing a large number of its data structures, so in the case | |
3457 | of future memory faults, at least the fixed filesystem will be fully | |
3458 | written out. | |
3459 | ||
3460 | If a filesystem doesn't support imagic inodes, and e2fsck discovers an | |
3461 | imagic inode, it will offer to clear the imagic flag. | |
3462 | ||
3463 | E2fsck will now offer to clear the immutable flag on special files | |
3464 | (device/socket/fifos) when running it in non-preen mode. | |
3465 | ||
3466 | E2fsck will now set the filetype when creating /lost+found, and when | |
3467 | connected orphaned inodes to /lost+found. | |
3468 | ||
3469 | Debugfs's ncheck and icheck commands now handles the case where there | |
3470 | are bad blocks in the inode table without bombing out. | |
3471 | ||
3472 | The badblocks list processing code has been made more efficiently for | |
3473 | appending a large number of (ordered) badblocks to the badblocks list. | |
3474 | ||
3475 | Some minor man page updates. | |
3476 | ||
3477 | Fsck now allows interactive e2fsck's when using fsck -As (not a common | |
3478 | mode, but some people like to do this in boot scripts for silly reasons). | |
3479 | ||
3480 | Programmer's notes: | |
3481 | ------------------- | |
3482 | ||
3483 | The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet | |
3484 | with the problem code convention. | |
3485 | ||
3486 | The badblocks list regression test program has been updated to work | |
3487 | with previously made API name changes. | |
3488 | ||
3489 | The ext2fs_free() command now uses the new badblocks API to avoid | |
3490 | using the compatibility layer. | |
3491 | ||
3492 | Added new regression test cases; the run_e2fsck test script now | |
3493 | supports the ability for a test case to run a prepratory command | |
3494 | before running e2fsck. | |
3495 | ||
28e1194e TT |
3496 | E2fsprogs 1.17 (October 26, 1999) |
3497 | ================================= | |
3498 | ||
3499 | Fixed nasty typo in fsck which caused parallelized fsck's to go into an | |
3500 | infinite loop. | |
3501 | ||
3502 | Fixed a bug in fsck where it used strncmp to compare a binary UUID, | |
3503 | thus potentially causing problems if a binary UUID contained a NULL | |
3504 | character. | |
3505 | ||
3506 | E2fsck now uses stricter checks for directory entries in pass 2: | |
3507 | zero-length filenames are not allowed; neither are 8 byte long | |
3508 | directory entries. | |
3509 | ||
3510 | The debugfs "dirty" command now clears the filesystem valid bit. | |
3511 | (Previously this just set the dirty-as-in-needs-writing-out-to-disk | |
3512 | bit in the in-core superblock image. The new functionality is more | |
3513 | what the user expects, and is more useful.) | |
3514 | ||
3515 | Added a debugging hook to test parallel fsck; if the environment | |
3516 | variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive | |
3517 | will be checked in parallel when they normally would not be. | |
3518 | ||
3519 | Programmer's notes: | |
3520 | ------------------- | |
3521 | ||
3522 | Fixed some #ifdef's for compilation under the Hurd OS. | |
3523 | ||
3524 | Fixed minor W2K compatibility problems. | |
3525 | ||
3526 | Fixed some miscellaneous GCC warnings. | |
3527 | ||
3528 | ||
8a31ffef TT |
3529 | E2fsprogs 1.16 (October 22, 1999) |
3530 | ================================= | |
3531 | ||
3532 | Fixed a race condition bug in fsck; when printing a progress bar, if | |
3533 | checking multiple filesystems in parallel, it was possible for fsck to | |
3534 | send e2fsck a SIGUSR1 signal before e2fsck had installed its signal | |
3535 | handler, which would cause it to terminate with a signal 10. | |
3536 | ||
3537 | E2fsck now properly handles filesystems that have the | |
3538 | INCOMPAT_FILETYPE feature turned on. It can be used to convert a | |
3539 | filesystem into using or not using FILETYPE feature. | |
3540 | ||
3541 | E2fsck now properly handles filesystems that have the IMAGIC feature | |
3542 | turned on (this is used on Linux AFS servers). | |
3543 | ||
3544 | The mke2fs program now creates filesystems that have the filetype and | |
3545 | sparse_superblock features enabled by default, unless it is run on a | |
3546 | pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, | |
3547 | so there is now a new flag -O which allows the user to specify with | |
3548 | which features she would like to create the filesystem; "mke2fs -O | |
3549 | none" will create a filesystsem compatible with 2.0 kernels. | |
3550 | ||
3551 | The tune2fs program now has a -O option which allows the user to set | |
3552 | and reset "safe" filesystem features. Currently, the only ones which | |
3553 | allows to be modified are the filetype and sparse_superblock features. | |
3554 | Note setting or clearing either feature will require running e2fsck on | |
3555 | the filesystem afterwards. (n.b. Clearing the sparse_superblock feature | |
3556 | requires that there is enough free space on the filesystem for the | |
3557 | extra superblocks which will be created by e2fsck.) | |
3558 | ||
3559 | Debugfs can now set and print filesystem features in the superblock | |
3560 | using the "features" command. Dumpe2fs will print out the complete | |
3561 | set of features when listing the superblock. | |
3562 | ||
3563 | Dumpe2fs has new options -f (force) and -h (header-only). | |
3564 | ||
3565 | Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead | |
3566 | message to come up. This could happen when decrementing or | |
3567 | incrementing a link count could result in an overflow. | |
3568 | ||
3569 | Fixed a bug in e2fsck where the block count on the lost+found | |
3570 | directory would not be properly incremented when the directory was | |
3571 | expanded to the point where an indirect block needed to be allocated. | |
3572 | ||
3573 | E2fsck now makes some additional sanity checks on the superblock to | |
3574 | avoid crashing or giving a memory allocation error if some of the | |
3575 | values in the superblock are unresonable (but the superblock otherwise | |
3576 | looks valid). | |
3577 | ||
3578 | Fixed a bug in e2fsck where a very badly corrupted filesystem might | |
3579 | require two passes to completely fix the filesystem. This happened if | |
3580 | an inode claimed blocks that was part of the filesystem metadata | |
3581 | (typically, when garbage was written into an inode table or indirect | |
3582 | block, since this kind of filesystem corruption normally doesn't | |
3583 | happen otherwise). | |
3584 | ||
3585 | On the Alpha, glibc declares st_flags although it isn't actually used; | |
3586 | the configure script was improved to detect this case so that | |
3587 | e2fsprogs can avoid using the non-functional stat field. | |
3588 | ||
3589 | The manual pages were updated to use a more consistent formatting | |
3590 | style consistent with standard Unix man pages. Mke2fs's man page | |
3591 | added documentation for a few previously undocumented options. | |
3592 | ||
3593 | Fixed minor display bugs in tune2fs and mke2fs. | |
3594 | ||
3595 | Programmer's notes: | |
3596 | ------------------- | |
3597 | ||
3598 | Improved portability of e2fsprogs to non-Unix systems (in particular, NT). | |
3599 | ||
3600 | Added features to parse and print feature strings into the e2p library. | |
3601 | (e2p_feature2string, e2p_string2feature, e2p_edit_feature). | |
3602 | ||
3603 | ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories | |
3604 | whose directory entries contain proper filetype information if the | |
3605 | filesystem supports it. | |
3606 | ||
3607 | ext2fs_link() now uses the low 3 bits of its flags parameter to pass | |
3608 | the directory entry filetype information. This is used to set the | |
3609 | directory entry filetype information if the filesystem supports it. | |
3610 | ||
3611 | Fixed a bug in ext2fs_expand_dir() where the block count in a | |
3612 | directory's inode would not be properly incremented when the directory | |
3613 | was expanded to the point where an indirect block needed to be | |
3614 | allocated. | |
3615 | ||
3616 | ||
a39f3efe | 3617 | E2fsprogs 1.15 (July 18, 1999) |
e2a99be6 | 3618 | ============================== |
6d53db3f TT |
3619 | |
3620 | Add configuration checks so that e2fsprogs will compile cleanly on | |
3621 | Linux 2.3 kernels that have renamed i_version to i_generation. | |
3622 | ||
e2a99be6 TT |
3623 | E2fsck now prints a progress/completion bar (and not just a simple |
3624 | spinner) if the -C0 option is requested or if it receives a SIGUSR1 | |
3625 | signal. Fsck will automatically manage the (potentially muliple) | |
3626 | e2fsck processes to print completion bars if it is given a -C option, | |
3627 | with the right thing happening if multiple filesystems are being | |
3628 | checked in parallel. | |
3629 | ||
3630 | Mke2fs now has better automatic hueristics to determine the filesystem | |
3631 | parameters to be used for a particular filesystem. Added a new option | |
3632 | -T which allows the user to specify how the filesystem is to be used, | |
3633 | which helps mke2fs do a better job selecting the filesystem parameters. | |
3634 | ||
a39f3efe TT |
3635 | Mke2fs now creates revision 1 filesystems by default, and with the |
3636 | sparse superblock feature enabled. The sparse superblock feature is | |
8a31ffef TT |
3637 | not understood by Linux 2.0 kernels, so they will only allow read-only |
3638 | mounts of filesystems with this sparse superblocks. | |
a39f3efe | 3639 | |
6d53db3f TT |
3640 | Fix bug where if /dev/null couldn't be opened (should never happen), |
3641 | e2fsck would hang in a tight loop. | |
3642 | ||
3643 | Make e2fsck handle the case where /lost+found isn't a directory. | |
3644 | ||
3645 | E2fsck now uses mallinfo if it exists to get accurate statistics about | |
3646 | its memory usage. | |
3647 | ||
3648 | Fix bug in e2fsck where it wouldn't check to see if a disconnected | |
3649 | inode had any problems before connecting it to /lost+found. | |
3650 | ||
3651 | Add check to e2fsck so it makes sure that total number of inodes in | |
3652 | the filesystem is a sane number. | |
3653 | ||
3654 | Fix fencepost error when clearing an the end of the block bitmap which | |
3655 | caused the last block in the bitmap not to get cleared. | |
3656 | ||
3657 | Cleaned up a number of messages in e2fsck: | |
3658 | * The message "Group's #'s copy of the group descriptor..." | |
3659 | was fixed so that the correct number would be displayed. | |
3660 | * Added missing space in the "disk write-protected" error messsage | |
3661 | * Cleaned up the error message printed when a non-interactive | |
3662 | e2fsck needs to abort a check because the filesystem | |
3663 | appears to be mounted. | |
3664 | ||
3665 | Added a new command-line utility, uuidgen, which will create and print | |
3666 | a UUID. | |
3667 | ||
3668 | Make debugfs's icheck command more robust by checking to make sure an | |
3669 | inode has valid blocks before interarting over the inode's blocks. | |
3670 | ||
3671 | UUID generation now uses a random-based scheme whenever possible to | |
3672 | prevent potential privacy problems. | |
3673 | ||
3674 | Man pages for all of the UUID functions in the lirbary were added. | |
3675 | ||
3676 | Fixed bug in fsck so it won't coredump if a filesystem not in | |
3677 | /etc/fstab is given to it. | |
3678 | ||
3679 | Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab | |
3680 | that most of the other mount utilities understands. | |
3681 | ||
3682 | Mke2fs will make a filesystem even if it appears mounted if the force | |
3683 | option is given. | |
3684 | ||
3685 | Dumpe2fs has new command-line options which allow a filesystem expert | |
3686 | to specify the superblock and blocksize when opening a filesystem. | |
3687 | This is mainly useful when examining the remains of a toasted | |
3688 | filesystem. | |
3689 | ||
3690 | The badblocks program has been updated to display correctly on disks | |
3691 | with large block numbers. | |
3692 | ||
e2a99be6 TT |
3693 | The badblocks program no longer gives spurious errors when errors |
3694 | occur on non-block boundaries, which is common if the blocksize is | |
3695 | larger than 1k. | |
3696 | ||
6d53db3f TT |
3697 | Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the |
3698 | MKE2FS_SYNC environment variable is set. This is to work around a VM | |
3699 | bug in the 2.0 kernel. I've heard a report that a RAID user was able | |
a39f3efe TT |
3700 | to trigger it even using a 2.2 kernel, but hopefully it will not be |
3701 | needed for most Linux 2.2 users. | |
6d53db3f TT |
3702 | |
3703 | Fixed miscellaneous documentation and man pages. | |
3704 | ||
3705 | Programmer's notes: | |
3706 | ------------------- | |
3707 | ||
3708 | Cleaned up functions such as pass1_get_blocks, pass1_read_inode which | |
3709 | in e2fsck's pass1.c really should have been static. | |
3710 | ||
3711 | The return value of the uuid_compare() function was changed to make it | |
3712 | match with the convetions used by strcmp, memcmp, and Paul Leach's | |
3713 | UUID sample document. | |
3714 | ||
3715 | The "make depend" process has now been made more automated; it now | |
3716 | automatically word-wraps the dependencies, and only replaces source | |
3717 | Makefile.in if there has been a change in the dependencies. Also, a | |
3718 | top-level "make depend" now recurses through all the subdirectories | |
3719 | automatically. | |
3720 | ||
3721 | The Makefile in .../util has been changed so that subst is built using | |
3722 | the native C compiler during a cross-compilation, since the subst | |
3723 | program is only used during the build process. Also add an explicit | |
3724 | rule to build util/subst by cd'ing to the correct directory and | |
3725 | running Makefile. | |
3726 | ||
3727 | The man directories are defined in terms mandir, so that the configure | |
3728 | script can override the location of the manual pages. | |
3729 | ||
3730 | The config files have been updated to recognize new machine types for | |
3731 | both the i386 and alpha families. | |
3732 | ||
3733 | Fsck has been modified so that it will accurately create an | |
3734 | fsck_instance even when the noexecute flag is set. This allows for | |
3735 | accurate debugging of the fsck pass structure. Also, when the verbose | |
3736 | flag is given twice, fsck will print debugging information about when | |
3737 | fsck is waiting for jobs to finish. | |
3738 | ||
3739 | ||
14790ed7 TT |
3740 | E2fsprogs 1.14 (January 9, 1999) |
3741 | ================================ | |
3742 | ||
3743 | Fix the fstab parsing code so that it can handle blank lines and | |
3744 | comment characters. Also, missing pass numbers need to be treated as | |
3745 | zero. | |
3746 | ||
3747 | Fixed a bug in e2fsck where under some circumstances (when e2fsck | |
3748 | needs to restart processing after fixing an egregious inconsistency) | |
3749 | it would try to access already freed memory. | |
3750 | ||
3751 | E2fsck now prints non-printable characters in directory entries and | |
3752 | pathnames using '^' and 'M-' notation. | |
3753 | ||
3754 | Fixed chattr so that it will ignore symbolic links when doing | |
3755 | recursive descent traversals. For both chattr and lsattr, no longer | |
3756 | print the version string unless the -V option is given. | |
3757 | ||
3758 | Allow the system administrator to directly specify the number of | |
3759 | inodes desired in the filesystem, for some special cases where this is | |
3760 | necessary. | |
3761 | ||
3762 | Fix portability problems so that e2fsprogs can be compiled under Linux | |
3763 | 1.2 systems and Solaris systems. | |
3764 | ||
3765 | Update the config.guess file with a more recent version that will | |
3766 | identify newer Linux platforms. | |
3767 | ||
3768 | Programmer's notes | |
3769 | ------------------ | |
3770 | ||
3771 | Ext2fs_read_inode and ext2fs_write_inode will now return an error if | |
3772 | an inode number of zero is passed to them. | |
3773 | ||
556ad132 TT |
3774 | E2fsprogs 1.13 (December 15, 1998) |
3775 | ================================== | |
3776 | ||
3777 | Fixed a bug in debugfs where an error messages weren't getting printed | |
3778 | when the ext2 library routines to read inodes returned errors in the | |
3779 | stat, cmri and rm commands. | |
3780 | ||
3781 | Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is | |
3782 | provided, it won't create an inode table smaller than the minimum | |
3783 | number of inodes required for a proper ext2 filesystem. | |
3784 | ||
3785 | Fsck now parses the /etc/fstab file directly (instead of using | |
3786 | getmntent()), so that it can distinguish between a missing pass number | |
3787 | field and pass number field of zero. This caused problems for | |
3788 | diskless workstations where all of the filesystems in /etc/fstab have | |
3789 | an explicit pass number of zero, and fsck could not distinguish this | |
3790 | from a /etc/fstab file with missing pass numbers. | |
3791 | ||
3792 | E2fsck will create a /lost+found directory if there isn't one in the | |
3793 | filesystem, since it's safer to create the lost+found directory before | |
3794 | it's needed. | |
3795 | ||
3796 | Fixed e2fsck so that it would detect bogus immutable inodes which | |
3797 | happen to be sockets and FIFO files, and offer to clear them. | |
3798 | ||
3799 | If a filesystem has multiple reasons why it needs to be checked, and | |
3800 | one of the reasons is that it is uncleanly mounted, e2fsck will print | |
3801 | that as the reason why the filesystem is being checked. | |
3802 | ||
3803 | Cleaned up the output routines of mke2fs so that it doesn't overflow | |
3804 | an 80 column display when formating really big filesystems. | |
3805 | ||
3806 | Added a sanity check to e2fsck to make sure that file descriptors 0, | |
3807 | 1, 2 are open before opening the hard disk. This avoids a problem | |
3808 | where a broken program might exec e2fsck with those file descriptors | |
3809 | closed, which would cause disastrous results if the kernel returns a | |
3810 | file descriptor for the block device which is also used by FILE * | |
3811 | stdout. | |
3812 | ||
3813 | Fixed up the e2fsck progress reporting functions so that the values | |
3814 | reliably reach 100% at the completion of all of the e2fsck passes. | |
3815 | ||
3816 | Fixed minor documentation bugs in man pages and usage messages. | |
3817 | ||
3818 | Programmer's notes: | |
3819 | ------------------- | |
3820 | ||
3821 | Fixed a number of lint warnings in the ext2fs library and potential | |
3822 | portability problems from other OS's header files that might define | |
3823 | CPP macros for names like "max" and "min". | |
3824 | ||
3825 | ext2fs_badblocks_list_add() has been made more efficient when it needs | |
3826 | to grow the bad blocks list. | |
3827 | ||
3828 | Fixed a bug in e2fsck which caused it to dereference a freed pointer | |
3829 | just before exiting. | |
3830 | ||
3831 | Fixed the substition process for generating the mk_cmds and compile_et | |
3832 | scripts so that they will work outside of the build tree. | |
3833 | ||
3834 | Add sanity check to e2fsck so that if an internal routine | |
3835 | (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer | |
3836 | and causing a core dump. This should never happen, but... | |
3837 | ||
a569671a | 3838 | E2fsprogs 1.12 (July 9, 1998) |
21d53850 TT |
3839 | ================================== |
3840 | ||
3841 | E2fsprogs now works with glibc (at least with the version shipped wtih | |
3842 | RedHat 5.0). The ext2fs_llseek() function should now work even with | |
3843 | i386 ELF shared libraries and if llseek() is not present. We also | |
3844 | explicitly do a configure test to see if (a) llseek is in libc, and | |
3845 | (b) if llseek is declared in the system header files. (See standard | |
3846 | complaints about libc developers don't understand the concept of | |
3847 | compatibility with previous versions of libc.) | |
3848 | ||
c9833a60 TT |
3849 | The ext2fs library now writes out the block group number in each of |
3850 | the superblock copies. This makes it easier to automatically | |
3851 | determine the starting block group of the filesystem when the block | |
3852 | group information is trashed. | |
3853 | ||
3854 | Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, | |
101c84f2 TT |
3855 | which means that e2fsprogs will ignore the high 8 bits of the |
3856 | directory entry's name_len field, so that it can be used for other | |
3857 | purposes. | |
3858 | ||
3859 | Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. | |
3860 | E2fsprogs will now support filesystems with 64-bit sized files. | |
3861 | ||
3862 | Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. | |
3863 | ||
21d53850 TT |
3864 | Added new program "e2label", contributed by Andries Brouwer. E2label |
3865 | provides an easy-to-use interface to modify the filesystem label. | |
3866 | ||
a4b2d3ce TT |
3867 | Fixed bug so that lsattr -v works instead of producing a core dump. |
3868 | ||
21d53850 TT |
3869 | Fixed a minor bug in mke2fs so that all groups with bad superblock |
3870 | backup blocks are printed (not just the first one). | |
a4b2d3ce TT |
3871 | |
3872 | Mke2fs will check the size of the device, and if the user specifies a | |
3873 | filesystem size larger than the apparent size of the device it will | |
3874 | print a warning message and ask if the user wants to proceed. | |
3875 | ||
c9833a60 TT |
3876 | E2fsck has a new option -C, which sends completion information to the |
3877 | specified file descriptor. For the most part, this is intended for | |
3878 | programs to use, although -C 0 will print a spinning character to the | |
3879 | stdout device, which may be useful for users who want to see something | |
3880 | happening while e2fsck goes about its business. | |
3881 | ||
21d53850 TT |
3882 | Fixed a bug in e2fsck which could cause a core dump when it needs to |
3883 | expand the /lost+found directory, and sometimes the bitmaps haven't | |
3884 | been merged in. Also fixed a related bug where ext2fs_write_dir_block | |
3885 | was used to write out a non-directory block. (Which would be bad on a | |
3886 | non-Intel platform with byte swapping going on.) | |
3887 | ||
3888 | Fixed bug in e2fsck where it would print a "programming error" message | |
3889 | instead of correctly identifying where a bad block was in used when | |
3890 | the bad block was in a non-primary superblock or block group | |
3891 | descriptor. Also fixed a related bug when sparse superblocks are in | |
3892 | use and there is a bad block where a superblock or block group | |
3893 | descriptor would have been in a group that doesn't include a | |
3894 | superblock. | |
3895 | ||
3896 | Fixed a bug in e2fsck (really in libext2fs's dblist function) where if | |
3897 | the block group descriptor table is corrupt, it was possible to try to | |
3898 | allocate a huge array, fail, and then abort e2fsck. | |
3899 | ext2fs_get_num_dirs() now sanity checks the block group descriptor, | |
3900 | and subsitutes reasonable values if the descriptors are obviously bogus. | |
3901 | ||
3902 | If e2fsck finds a device file which has the immutable flag set and the | |
3903 | i_blocks beyond the normal device number are non-zero, e2fsck will | |
3904 | offer to remove it, since it's probably caused by garbage in the inode | |
3905 | table. | |
3906 | ||
3907 | When opening a filesystem, e2fsck specially checks for the EROFS error | |
3908 | code, and prints a specific error message to the user which is more | |
3909 | user friendly. | |
3910 | ||
3911 | If the filesystem revision is too high, change the e2fsck to print | |
3912 | that this is either because e2fsck is out of date, or because the | |
3913 | superblock is corrupt. | |
3914 | ||
3915 | E2fsck now checks for directories that have duplicate '.' and '..' | |
3916 | entries, and fixes this corruption. | |
3917 | ||
3918 | E2fsck no longer forces a sync of the filesystem (with attendant sleep | |
3919 | calls) at all times. The ext2fs_flush() function now performs a sync | |
3920 | only if it needed to write data blocks to disk. | |
3921 | ||
3922 | Fixed a minor bug in e2fsck's pass1b's file cloning function, where | |
3923 | certain errors would not be properly reported. | |
3924 | ||
3925 | Updated and expanded a few points in the man pages which users | |
3926 | complained wheren't explicit enough. | |
3927 | ||
3928 | Added special case byte-swapping code if compiling on the PowerPC, to | |
3929 | accomodate the strange big-endian variant of the ext2 filesystem that | |
3930 | was previously used on the PowerPC port. | |
3931 | ||
3932 | ||
3933 | Programmer's notes: | |
3934 | ------------------- | |
3935 | ||
3936 | Removed C++ keywords from the ext2fs libraries so that it could be | |
3937 | compiled with C++. | |
3938 | ||
3939 | E2fsck's internal organization has now been massively reorganized so | |
3940 | that pass*.c don't have any printf statements. Instead, all problems | |
3941 | are reported through the fix_problem() abstraction interface. E2fsck | |
3942 | has also been revamped so that it can be called as a library from a | |
3943 | application. | |
3944 | ||
3945 | Added new fileio primitives in libext2fs for reading and writing | |
3946 | files on an unmounted ext2 filesystem. This interface is now used by | |
3947 | debugfs. | |
3948 | ||
3949 | Added a new libext2fs function for mapping logical block numbers of | |
3950 | a file to a physical block number. | |
3951 | ||
3952 | Added a new libext2fs function, ext2fs_alloc_block(), which allocates | |
3953 | a block, zeros it, and updates the filesystem accounting records | |
3954 | appropriately. | |
3955 | ||
3956 | Added a new libext2fs function, ext2fs_set_bitmap_padding(), which | |
3957 | sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. | |
3958 | ||
3959 | The libext2fs functions now use a set of memory allocation wrapper | |
3960 | functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, | |
3961 | instead of malloc, free, and resize. This makes it easier for us to | |
3962 | be ported to strange environments where malloc, et. al. aren't | |
3963 | necessarily available. | |
3964 | ||
3965 | Change the libext2fs fucntion to return ext2-specific error codes | |
3966 | (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using | |
3967 | and depending on the existence of system error codes (such as EEXIST | |
3968 | and ENOENT). | |
3969 | ||
3970 | Renamed io.h to ext2_io.h to avoid collision with other OS's header | |
3971 | files. | |
3972 | ||
3973 | Add protection against ext2_io.h and ext2fs.h being included multiple | |
3974 | times. | |
3975 | ||
3976 | The types used for memory lengths, etc. have been made more portable. | |
3977 | In generla, the code has been made 16-bit safe. Added Mark | |
3978 | Habersack's contributed DOS disk i/o routines. | |
3979 | ||
3980 | Miscellaneous portability fixes, including not depending on char's | |
3981 | being signed. | |
3982 | ||
3983 | The io_channel structure has a new element, app_data, which is | |
3984 | initialized by the ext2fs routines to contain a copy of the filesystem | |
3985 | handle. | |
3986 | ||
3987 | ext2fs_check_directory()'s callback function may now return the error | |
3988 | EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to | |
3989 | really do the checking, despite the presence of the callback function. | |
3990 | ||
3991 | ||
bc210074 TT |
3992 | E2fsprosg 1.11 (June 17, 1997) |
3993 | ============================== | |
3994 | ||
3995 | Fixed e2fsck to detect (previously ignored) conflicts between the | |
3996 | superblock or block group descriptors and block bitmaps, inode | |
3997 | bitmaps, and inode tables. | |
3998 | ||
3999 | Fixed bug in e2fsck so that when the message printed out when a block | |
4000 | or inode bitmap conflicts with other data, it has the correct group | |
4001 | number. | |
4002 | ||
4003 | Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed | |
4004 | to badblocks. This meant that not all of the filesystem was being | |
4005 | tested for bad blocks! | |
4006 | ||
4007 | Fixed an array boundary overrun case which cropped up in | |
4008 | ext2fs_badblocks_list_test when a user tried running "mke2fs -c | |
4009 | -b 4096". | |
4010 | ||
4011 | Adjusted the number of columns printed by mke2fs when displaying the | |
4012 | superblock backups to avoid running over 80 columns when making a | |
21d53850 | 4013 | really big filesystem. |
bc210074 TT |
4014 | |
4015 | Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, | |
4016 | dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar | |
4017 | fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). | |
4018 | ||
4019 | Programmer's notes: | |
4020 | ------------------- | |
4021 | ||
4022 | Fixed install rule in lib/ss so that ss_err.h is actually getting | |
4023 | installed. | |
4024 | ||
4025 | Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting | |
4026 | bassed back to the caller. | |
4027 | ||
4028 | Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been | |
4029 | setting the current inode number (which meant this function wasn't | |
4030 | working at all). | |
4031 | ||
4032 | Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all | |
4033 | blocks in the bitmap when increasing the size of the bitmap. | |
4034 | ||
4035 | Changed the initial number of blocks allocated by ext2fs_init_dblist() | |
4036 | to be more realistic. | |
4037 | ||
4038 | Added a new function ext2fs_allocate_group_table, which sets up the | |
4039 | group descriptor information (and allocates inode and block bitmaps, | |
4040 | and inode tables for a particular group). The function was created by | |
4041 | factoring out code form ext2fs_allocate_tables(). | |
4042 | ||
4043 | Added a new function ext2fs_move_blocks which takes a bitmap of the | |
4044 | blocks to be moved, and moves them to another location on the | |
4045 | boardboard. | |
4046 | ||
4047 | Make the unix_io channel's io_channel_flush implementation calls sync() | |
4048 | to to flush the kernel buffers to disk. | |
4049 | ||
4050 | Added a new function ext2fs_dblist_count returns the number of | |
4051 | directory blocks in dblist. | |

4054 | E2fsprogs 1.10 (April 24, 1997) |
4055 | =============================== | |
4056 | ||
4057 | Mke2fs once again defaults to creating revision #0 filesystems, since | |
4058 | people were complaining about breaking compatibility with 1.2 kernels. | |
4059 | Warning messages were added to the mke2fs and tune2fs man pages that | |
4060 | the sparse superblock option isn't supported by most kernels yet (1.2 | |
4061 | and 2.0 both don't support parse superblocks.) | |
4062 | ||
4063 | Added new flag to mke2fs, -R <raid options>, which allows the user to | |
4064 | tell mke2fs about the RAID configuration of the filesystem. Currently | |
4065 | the only supported raid option is "stride" which specifies the width | |
4066 | of the RAID stripe. | |
4067 | ||
4068 | Fixed bug in e2fsck where pass1b would bomb out if there were any | |
4069 | blocks marked bad in the inode table. | |
4070 | ||
4071 | Fixed rare bug in mke2fs where if the user had a very unlucky number | |
4072 | of blocks in a filesystem (probability less than .002) the resulting | |
4073 | filesystem would be corrupt in the last block group. | |
4074 | ||
4075 | Fixed bug where if e2fsck tried to allocate a block to fix a | |
4076 | filesystem corruption problem and the filesystem had no free blocks, | |
4077 | ext2fs_new_block() would loop forever. | |
4078 | ||
4079 | The configure script now checks explicitly to see if "-static" works, | |
4080 | since that can't be assumed to be true --- RedHat doesn't install | |
4081 | libc-static by default. | |
4082 | ||
4083 | Fixed bug in libext2's block iterator functions where under some | |
4084 | cirmcustances, file with holes would cause the bcount parameter to the | |
4085 | callback function to be incorrect. This bug didn't affect any of | |
4086 | e2fsprogs programs, but it was discovered by Paul Mackerras, the | |
4087 | author of the PPC boot loader. | |
4088 | ||
4089 | Removed use of static variables to store the inode cache in libext2fs. | |
4090 | This caused problems if more than one filesystem was accessed via | |
4091 | libext2fs (static variables in libraries are generally a bad idea). | |
4092 | Again, this didn't affect e2fsprogs programs, but it was discovered by | |
4093 | Paul Mackerras. | |
4094 | ||
4095 | Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 | |
4096 | will compile cleanly with 1.2.13 kernels (even with a.out shared | |
4097 | libraries!) | |
4098 | ||
4099 | Programmer's notes: | |
4100 | ------------------- | |
4101 | ||
4102 | Added new functions to duplicate an ext2 filesystem handle, and its | |
4103 | associated substructure. New functions: ext2fs_dup_handle(), | |
4104 | ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). | |
4105 | Other structures, such as the io_channel and the inode_cache, now have | |
4106 | a ref count so that they only get freed when they are no longer used | |
4107 | by any filesystem handle. (These functions were added as part of the | |
4108 | development effort for an ext2 resizer). | |
4109 | ||
2ecc6fef TT |
4110 | E2fsprogs 1.09 (April 14, 1997) |
4111 | =============================== | |
4112 | ||
4113 | Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was | |
4114 | accidentally introduced in the 1.08 release. The overhead calculation | |
4115 | was accidentally removed, which caused ext2fs_initialize() to not | |
4116 | notice when the filesystem size needed to be adjusted down because | |
4117 | there wasn't enough space in the last block group. | |
4118 | ||
4119 | Fixed bug in version parsing library routine; it was always parsing | |
4120 | the library version string, instead of using the passed-in string. | |
4121 | ||
4122 | Clarified chattr man page. | |
4123 | ||
24757fa0 TT |
4124 | E2fsprogs 1.08 (April 10, 1997) |
4125 | =============================== | |
4126 | ||
4127 | E2fsck 1.07 was very slow when checking very large filesystems with a | |
4128 | lot of files that had hard links (i.e., news spools). This was fixed | |
4129 | by seriously revamping the icount abstraction. Added a formal test | |
4130 | suite for the icount abstraction. | |
4131 | ||
4132 | Debugfs now has a "-l" option to the "ls" command, which lists the | |
4133 | inode number, permissions, owner, group, size, and name of the files | |
4134 | in the directory. | |
4135 | ||
4136 | Fix a bug in e2fsck where when a directory had its blocks moved to | |
4137 | another location during the pass 1b processing, the directory block | |
4138 | list wasn't updated, so pass 2 wouldn't check (and correct) the | |
4139 | correct directory block. | |
4140 | ||
4141 | E2fsck will now treat inodes which contain blocks which are claimed by | |
4142 | the filesystem metadata by treating them as multiply claimed blocks. | |
4143 | This way, the data in those blocks can be copied to a new block during | |
4144 | the pass 1b--1d processing. | |
4145 | ||
4146 | E2fsck will attempt to determine the correct superblock number and | |
4147 | display it in the diagnostic and warning messages if possible. | |
4148 | ||
4149 | Add support for a new (incompatible) feature, "sparse_super". This | |
4150 | feature reduces the number of blocks which contain copies of backup | |
4151 | superblocks and block group descriptors. (It is only an incompatible | |
4152 | feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now | |
4153 | support a new -s option; e2fsck will recognize filesystems built with | |
4154 | this feature turned on. | |
4155 | ||
4156 | E2fsck now checks the library to make sure is the correct version, | |
4157 | using new library functions. (This helps to diagnose incorrectly | |
4158 | installed e2fsprogs distributions.) | |
4159 | ||
4160 | Dumpe2fs now prints more information; its now prints the the | |
4161 | filesystem revision number, the filesystem sparse_super feature (if | |
4162 | present), the block ranges for each block group, and the offset from | |
4163 | the beginning of the block group. | |
4164 | ||
4165 | Mke2fs now distributes the inode and block bitmap blok so that the | |
4166 | won't be concentrated in one or two disks in RAID/striping setups. | |
4167 | Also, if the user chooses a 2k or 4k block group, mke2fs will try to | |
4168 | choose the largest blocks per group that be chosen. (For 2k blocks, | |
4169 | you can have up to 16384 blocks/group; for 4k blocks, you can have up | |
4170 | to 32768 blocks/group.) Previously mke2fs would not allow | |
4171 | specification of more than 8192 blocks per group, even if you were | |
4172 | using a 2k or 4k block group. | |
4173 | ||
4174 | Programmer's notes: | |
4175 | ------------------- | |
4176 | ||
4177 | Added a new function ext2fs_create_icount2() which takes a "hint" | |
4178 | argument. This hint argument presets the icount array with the list | |
4179 | of inodes which actually need to be in the icount array. This really | |
4180 | helps to speed up e2fsck. | |
4181 | ||
4182 | Added a new function ext2fs_icount_validate() which checks the rep | |
4183 | invariant for the icount structure. This is used mostly for testing. | |
4184 | ||
4185 | The error mesasage given when a bad inode number is passed to | |
4186 | test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of | |
4187 | EXT2FS_UNMARK_ERROR). | |
4188 | ||
4189 | Added a new function ext2fs_set_dir_block which sets the block of a | |
4190 | dblist entry, given the directory inode and blockcnt. | |
4191 | ||
4192 | Added a new function ext2fs_get_library_version() which returns the | |
4193 | current library version, and ext2fs_parse_version_string() which | |
4194 | returns a version number based on a e2fsprogs version string. | |
4195 | ||
4196 | The icount functions will return EINVAL if the passed in inode number | |
4197 | is out of bounds. | |
4198 | ||
21c84b71 TT |
4199 | E2fsprogs 1.07 (March 9, 1997) |
4200 | ============================== | |
4201 | ||
4202 | E2fsck is now uses much less memory when checking really large | |
4203 | filesystems (or rather, filesystems with a large number of inodes). | |
4204 | Previously a filesystem with 1 million inodes required 4 megabytes of | |
4205 | memory to store inode count statistics; that storage requirement has | |
4206 | now been reduced to roughly half a megabyte. | |
4207 | ||
4208 | E2fsck can now properly deal with bad blocks appearing inside the | |
4209 | inode table. Instead of trying to relocate the inode table (which | |
4210 | often failed because there wasn't enough space), the inodes in the bad | |
4211 | block are marked as in use. | |
4212 | ||
4213 | E2fsck will automatically try to use the backup superblocks if the | |
4214 | primary superblocks have a bad magic number or have missing meta-data | |
4215 | blocks (or meta-data blocks which are out of range). | |
4216 | ||
4217 | E2fsck's pass 3 has been made more efficient; most noticeable on | |
4218 | filesystems with a very large number of directories. | |
4219 | ||
4220 | Completely revamped e2fsck's system of printing problem reports. It | |
4221 | is now table driven, to make them more easily customizeable and | |
4222 | extendable. Error messages which can be printed out during preen mode | |
4223 | are now one line long. | |
4224 | ||
4225 | Fixed e2fsck's filesystem swapping code so that it won't try to swap | |
4226 | fast symbolic links or deleted files. | |
4227 | ||
4228 | Fixed e2fsck core dumping when fixing a filesystem which has no | |
4229 | directories (not even a root directory). | |
4230 | ||
4231 | Added a check to e2fsck to make sure that the length of every | |
4232 | directory entry is a multiple of 4 (since the kernel complains if it | |
4233 | isn't). | |
4234 | ||
4235 | Added a check to e2fsck to make sure that a directory entry isn't a | |
4236 | link to the root directory, since that isn't allowed. | |
4237 | ||
4238 | Added a check to e2fsk to now make sure the '.' and '..' directory | |
4239 | entries are null terminated, since the 2.0 kernel requires it. | |
4240 | ||
4241 | Added check to write_bitmaps() to make sure the superblock doesn't get | |
4242 | trashed if the inode or block bitmap is marked as being block zero. | |
4243 | ||
4244 | Added checking of the new feature set fields in the superblock, to | |
4245 | avoid dealing with new filesystem features that this package wasn't | |
4246 | set up to handle. | |
4247 | ||
4248 | Fixed a fencepost error in ext2fs_new_block() which would occasionally | |
4249 | try to allocate a block beyond the end of a filesystem. | |
4250 | ||
4251 | When the UUID library picks a random IEEE 802 address (because it | |
4252 | can't find one from a network card), it sets the multicast bit, to | |
4253 | avoid conflicting with a legitimate IEEE 802 address. | |
4254 | ||
4255 | Mke2fs now sets the root directory's owner to be the real uid of the | |
4256 | user running mke2fs. If the real uid is non-zero, it also sets | |
4257 | the group ownership of the root directory to be the real group-id of | |
4258 | the user running mke2fs. | |
4259 | ||
4260 | Mke2fs now has more intelligent error checking when it is given a | |
4261 | non-existent device. | |
4262 | ||
4263 | When badblocks is given the -vv option, it now updates the block that | |
4264 | it is currently testing on every block. | |
4265 | ||
4266 | Fixed a bug in fsck where it wouldn't modify the PATH envirnoment | |
4267 | currently correctly if PATH wasn't already set. | |
4268 | ||
4269 | Shared libraries now built with dependencies. This allows the shared | |
4270 | library files to be used with dlopen(); it also makes the transition | |
4271 | to libc 6 easier, since ld.so can tell which libc a particular shared | |
4272 | library expects to use. | |
4273 | ||
4274 | Programmer's notes: | |
4275 | ------------------- | |
4276 | ||
4277 | Added new abstraction (defined in dblist.c) for maintaining a list of | |
4278 | blocks which belongs to directories. This is used in e2fsck and other | |
4279 | programs which need to iterate over all directories. | |
4280 | ||
4281 | Added new functions which test to see if a contiguous range of blocks | |
4282 | (or inodes) are available. (ext2fs_*_bitmap_range). | |
4283 | ||
4284 | Added new function (ext2_inode_has_valid_blocks) which returns true if | |
4285 | an inode has valid blocks. (moved from e2fsck code). | |
4286 | ||
4287 | Added new function (ext2fs_allocate_tables) which allocates the | |
4288 | meta-data blocks as part of initializing a filesystem. (moved from | |
4289 | mke2fs code). | |
4290 | ||
4291 | Added a new I/O manager for testing purposes. It will either allow a | |
4292 | program to intercept I/O requests, or print debugging messages to | |
4293 | trace the activity of a program using the I/O manager. | |
4294 | ||
4295 | The badblocks_list functions now store the bad blocks in a sorted | |
4296 | order, and use a binary search to speed up badblocks_list_test. | |
4297 | ||
4298 | The inode scan function ext2fs_get_next_inode() may now return a soft | |
4299 | error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in | |
4300 | those cases where part of an inode table is missing or there is a bad | |
4301 | block in the inode table. | |
4302 | ||
4303 | Added a new function (ext2fs_block_iterate2) which adds new arguments to | |
4304 | the callback function to return a pointer (block and offset) to the | |
4305 | reference of the block. | |
4306 | ||
4307 | Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an | |
4308 | application to jump to a particular block group while doing an inode | |
4309 | scan. | |
4310 | ||
4311 | The badblocks list functions were renamed from badblocks_* to | |
4312 | ext2fs_badblocks_*. Backwards compatibility functions are available | |
4313 | for now, but programs should be modified to use the new interface. | |
4314 | ||
4315 | Some of the library functions were reorganized into separate files to | |
4316 | reduce the size of some programs which statically link against the | |
4317 | ext2 library. | |
4318 | ||
4319 | Put in some miscellaneous fixes for the Alpha platform. | |
4320 | ||
5c576477 TT |
4321 | |
4322 | E2fsprogs 1.06 (October 7, 1996) | |
4323 | ================================ | |
4324 | ||
4325 | Fixed serious bug in e2fsck: if the block descriptors are bad, don't | |
4326 | smash the backup copies in ext2fs_close(). (The problem was that when | |
4327 | e2fsck -p discovered the problem, while it was closing the filesystem | |
4328 | and exiting, it was also blowing away the backup superblocks on the | |
4329 | disk, which was less than friendly.) We now make it the case that we | |
4330 | only write out the backup superblock and the back block descriptors if | |
4331 | the filesystem is completely free from problems. | |
4332 | ||
4333 | Fixed a bug in block_interate in the lib/ext2fs library which caused | |
4334 | e2fsck to fail on GNU Hurd-created filesystems. | |
4335 | ||
4336 | Add support for Linux/FT's bootloader, which actually uses | |
4337 | EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want | |
4338 | to clear the inode. | |
4339 | ||
4340 | Add support for the "A" (no atime update) attribute. (Note: this | |
4341 | attribute is not yet in production kernels.) | |
4342 | ||
4343 | The test suite is not automatically run when doing a "make all" from | |
4344 | the top level directory. Users should manually run "make check" if | |
4345 | they wish to run the test suite. | |
4346 | ||
4347 | Upon a preenhalt(), make the printed message more explicit that | |
4348 | running e2fsck "MANAULLY" means without the -p or -a options. | |
4349 | ||
4350 | In e2fsck, if a disconnected inode is zero-length, offer to clear it | |
4351 | instead of offering to connect it to lost+found. | |
4352 | ||
4353 | In e2fsck, if a filesystem was just unmounted uncleanly, and needs | |
4354 | e2fsck to be run over it, change e2fsck to explicitly display this | |
4355 | fact. | |
4356 | ||
4357 | For dumpe2fs and e2fsck, cause the -V option to print out which | |
4358 | version of the ext2fs library is actually getting used. (This will | |
4359 | help detect mismatches of using a 1.06 utility with a 1.05 library, | |
4360 | etc.) | |
4361 | ||
4362 | Programmers' notes: | |
4363 | ------------------- | |
4364 | ||
4365 | EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits | |
4366 | the naming convention. | |
4367 | ||
4368 | In ext2fs_initialize(), make sure the description for the inode bitmap | |
4369 | is correctly initialize. | |
4370 | ||
4371 | Fixed minor type typo in ext2fs_allocate_generic_bitmap(); | |
4372 | ||
fc6d9d51 TT |
4373 | E2fsprogs 1.05 (September 7, 1996) |
4374 | ================================== | |
4375 | ||
4376 | Add support for new fields in the ext2 superblock --- volume name, | |
4377 | volume UUID, and last mounted field. Dumpe2fs displays these fields, | |
4378 | tune2fs and mke2fs allows you to set them. E2fsck will automatically | |
4379 | generate a UUID for those volumes that don't have them. | |
4380 | ||
4381 | Put in support for e2fsck to recognize HURD specific ext2 features --- | |
4382 | most notably, the translator block. The e2fsprogs tools will now use | |
4383 | the creator_os field in the superblock to correctly handle different | |
4384 | OS-specific variants of the ext2 filesystem. | |
4385 | ||
4386 | E2fsck now fixes inodes which have a the deletion time set, but which | |
4387 | have a non-zero i_link_count field by offering to clear the deletion | |
4388 | time. Previously e2fsck assumed that the inode was deleted (per 0.3c | |
4389 | ext2 kernel behavior) and offered to unlink the file. | |
4390 | ||
4391 | If e2fsck sets the clean bit, but nothing else, set the exit code | |
4392 | FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it | |
4393 | set the filesystem valid bit when it was previously cleared. :-) This | |
4394 | was needed to make the HURD fsck driver happy. | |
4395 | ||
4396 | If the user refuses to attach an unattached inode, e2fsck will no | |
4397 | longer set the inode's link count. Otherwise, the inode would end up | |
4398 | getting marked as unused, which might cause loss of data later. | |
4399 | ||
4400 | Make the message issued by e2fsck when the superblock is corrupt less | |
4401 | confusing for users. It now mentions that another reason for the | |
4402 | "corrupt superblock" message might be that the partition might not be | |
4403 | an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) | |
4404 | ||
4405 | Make the libext2 library more robuest so that e2fsck won't coredump on | |
4406 | an illegal superblock where the blocksize is zero. (f_crashdisk is | |
4407 | the test case). | |
4408 | ||
4409 | By default, create filesystems where the default checkinterval is 6 | |
4410 | months (180 days). Linux servers can be robust enough that 20 reboots | |
4411 | can be a long, long time. | |
4412 | ||
4413 | Added configure flag --enable-old-bitops, which forces the bitops to | |
4414 | use the old (native) bitmask operations. By default on the sparc | |
4415 | platform, the standard ext2 bit ordering is now used. | |
4416 | ||
4417 | Added a new feature to e2fsck to byte-swap filesystems; this can be | |
4418 | used to convert old m68k filesystems to use the standard byte-order | |
4419 | storage for the superblock, inodes, and directory blocks. This | |
4420 | function is invoked by using the '-s' option to e2fsck. | |
4421 | ||
4422 | Debugfs's "dump" command has been enhanced so that it writes out the | |
4423 | exact size of the file so that the nulls at the end of the file are | |
4424 | eliminated. The command also accept a new "-p" option which will | |
4425 | attempt preserve to preserve the ownernship, permissions, and | |
4426 | file modification/access times. | |
4427 | ||
4428 | Debugfs has two new options, -f and -R. The -R option allows the user | |
4429 | to execute a single debugfs command from the command line. The -f | |
4430 | option allows the user to specify a "command file" containing debugfs | |
4431 | commands which will get executed. | |
4432 | ||
4433 | Dumpe2fs now pretty prints the check interval, instead of just | |
4434 | printing the check interval as a number of seconds. | |
4435 | ||
4436 | Fix bugs in debugfs: the params command when no filesystem is opened | |
4437 | no longer causes a core dump. It is now possible to unlink a file | |
4438 | when a pathame containing a '/' is specified. | |
4439 | ||
4440 | Tune2fs has a new -C option which sets the number of times the | |
4441 | filesystem has been mounted. | |
4442 | ||
4443 | Fix the chattr '-v' option so that it actually works. Chattr was | |
4444 | being buggy about the -v option parsing. | |
4445 | ||
4446 | Programmers' notes: | |
4447 | ------------------- | |
4448 | ||
4449 | The directory lib/uuid contains a set of library routines to generate | |
4450 | DCE compatible UUIDs. | |
4451 | ||
4452 | Extended ext2fs_namei() to handle symbolic links. Added new function | |
4453 | ext2fs_nami_follow() which will follow last symbolic link in the case | |
4454 | where the pathname points to a sym link. | |
4455 | ||
4456 | The ext2fs_block_iterate function will now return the HURD translator | |
4457 | block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the | |
4458 | iterator to return data blocks only. The ext2fs.h file now defines | |
4459 | constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and | |
4460 | BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block | |
4461 | count field of the iterator callback function. | |
4462 | ||
4463 | The test script driver now takes an optional second argument, which is | |
4464 | the test case to be run. This allows you to run a test case without | |
4465 | needing to run the entire test suite. | |
4466 | ||
4467 | On Linux ELF systems, install the .so files in the correct places | |
4468 | (/usr/lib). The .so files must be stored in the same directory as the | |
4469 | .a files. | |
4470 | ||
4471 | Fixed miscellaneous HURD compilation issues with header file being | |
4472 | included in the right order. | |
4473 | ||
4474 | Fixed debugfs so that it resets optind to zero, not one, since setting | |
4475 | optind to zero is more correct. | |

4478 | E2fsprogs 1.04 (May 16, 1996) |
4479 | ============================= | |
4480 | ||
4481 | First "official" (1.03 was a limited release only) to support building | |
4482 | e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 | |
4483 | kernels). | |
4484 | ||
4485 | This package includes a RPM specs file, that it can be built using the | |
4486 | RedHat Package Manager. | |
4487 | ||
4488 | E2fsck now prints a hint that if there are lots of incorrectly located | |
4489 | inode bitmaps, block bitmaps, and inode table blocks, the user might | |
4490 | want to try using e2fsck -b 8193 first, to see if that fares any | |
4491 | better. | |
4492 | ||
4493 | For ext2 filesystem written with the hurd, debugfs will now print out | |
4494 | the translator field when printing an inode structure. | |
4495 | ||
4496 | Lots of miscellaneous linking/installation cleanups: | |
4497 | ||
4498 | Libraries are now linked using a relative pathname, instead of | |
4499 | relying on -L working correct. It doesn't, in many cases, including | |
4500 | current versions of GNU ld. This guarantees that the build tree is | |
4501 | linking with the right libraries, instead of the ones installed in | |
4502 | /usr/lib. | |
4503 | ||
4504 | Header files, man pages, and the et/ss shell scripts are now | |
4505 | generated using a custom substitution script, instead of relying on | |
4506 | the configure script. This prevents needless recompilation of | |
4507 | files; in addition, the custom substitution script is much faster. | |
4508 | ||
4509 | e2fsck may now be linked dynamically, by using the | |
4510 | --enable-dynamic-e2fsck flag to configure. This is not recommended, | |
4511 | since it increases e2fsck's dependence on other files, but some | |
4512 | people need to save disk space, and other critical programs on their | |
4513 | systems were being linked dynamically anyway. | |
4514 | ||
4515 | Programs such as fsck which didn't need to be linked against | |
4516 | libext2fs (or mke2fs which didn't need to be linked against libe2p) | |
4517 | only link against libraries they actually need. Otherwise, those | |
4518 | programs would require the presense of libraries that otherwise | |
4519 | could be removed from a rescuse diskette. | |
4520 | ||
4521 | The ss include files are now installed correctly so they can | |
4522 | actually be used by another package. | |
4523 | ||
4524 | If the profiling libraries are built, they are now installed on a | |
4525 | "make install-libs". | |

4528 | E2fsprogs 1.03 (March 27, 1996) |
4529 | =============================== | |
4530 | ||
4531 | Change the m68k bit numbering for bitmasks to match the bit numbering | |
4532 | used by all other ext2 implementations. (This change was requested by | |
4533 | the m68k kernel development team.) | |
4534 | ||
4535 | Support (in-development) filesystem format revision which supports | |
4536 | (among other things) dynamically sized inodes. | |
4537 | ||
4538 | Fixed a bug in the ext2 library so that an intelligent error is | |
4539 | returned if mke2fs is run with a ridiculously small number of blocks | |
4540 | for a partition. | |
4541 | ||
4542 | Fixed a bug in the ext2 library which required that the device be | |
4543 | openable in read/write mode in order to determine its size. This | |
4544 | caused e2fsck -n to require read/write access when it was not | |
4545 | previously necessary. | |
4546 | ||
4547 | Fixed a bug in e2fsck which casued it to occasionally fail the test | |
4548 | suite depending on which version of the floating point library it was | |
4549 | using. | |
4550 | ||
4551 | Fixed a bug in e2fsck so that it now halts with a fatal error when | |
4552 | certain superblock consistency checks fail. Previously it continued | |
4553 | running e2fsck, with some potential confusing/damaging consequences. | |
4554 | ||
4555 | Added new flag to fsck which allows the root to be checked in parallel | |
4556 | with other filesytems. This is not the safest thing in the world to | |
4557 | do, but some system administrators really wanted it. | |
4558 | ||

4559 | Fixed -Wall flames in lib/ss. |

4562 | E2fsprogs 1.02 (January 16, 1996) | |
4563 | ================================= | |
4564 | ||
4565 | Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. | |
4566 | ||
4567 | Change e2fsck to print statistics of how many non-contiguous files are | |
4568 | on the system. Note that a file which is larger than 8k blocks, it is | |
4569 | guaranteed to be non-contiguous. | |
4570 | ||
4571 | In mke2fs, print a warning message if a user tries to format a whole | |
4572 | disk (/dev/hda versus /dev/hda1). If a user really wants to format a | |
4573 | whole disk, the -F (force) option forces mke2fs to format a whole disk | |
4574 | as a filesytem. | |
4575 | ||
4576 | Fix a bug in fsck where in some cases it might start checking | |
4577 | partitions in the next pass before it finishes checking partitions in | |
4578 | the current pass. This still won't cause two partitions on the same | |
4579 | disk will be checked, so it's rarely a problem in real life. | |
4580 | ||
4581 | Patch lsattr so that it won't hang when checking a named pipe. | |
4582 | ||
4583 | Minor compilation fixes: | |
4584 | * Fix the order of libraries that were linked in debugfs. | |
4585 | * Allow the sources to be compiled with -ansi turned on. |
