1 E2fsprogs 1.41-WIP-0617 (June 17, 2008) git ID: f1420977
2 ========================================================
4 Add support to badblocks to limit how quickly it reads from the disk
5 drive (so it can be used for background scrubbing), and so it will
6 abort after finding a given number of errors.
8 Add support for ext4 filesystem features, in particular extents,
9 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
10 support for checking journal checksums. Debugfs will print new
11 superblock and inode fields that were defined for ext4. For example,
12 the nanosecond and i_version fields of an inode, and the
13 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
14 Note: Resize2fs doesn't currently support the combination of flex_bg
15 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
17 Tune2fs can support migrating a filesystem from using 128 byte inodes
18 to 256 byte inodes, so it can take advantage of the full features of
21 Add support for "undo" support. E2fsck and mke2fs can optionally
22 record an undo log which can replayed by the program e2undo.
24 E2fsck will display a more understandable message when the last check
25 field in the superblock is in the future. (Addresses Debian Bug:
28 Speed up how mke2fs writes the journal data blocks by writing the disk
29 blocks in larger chunks.
31 Add more paranoid checks for LVM volumes and swap partitions in
32 blkid's probe function, to reduce the chances of false positives.
34 The mke2fs program now has a much more sophisticated system for
35 controlling configuration parameters of a newly created filesystem
36 based on a split filesystem and usage type system. The -t option to
37 mke2fs was a deprecated alias to -c; it now specifies a filesystem
38 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
39 separated usage list. The filesystem type information and type
40 information is used to extract configuration parameters from the
41 /etc/mke2fs.conf file.
43 Resize2fs will now print the minimum needed filesystem size if given
44 the -P option, and will resize the filesystem to the smallest possible
45 size if given the -M option.
47 The mke2fs program will no longer complain and request the -f option
48 when the user tries to create a filesystem with greater than 2**31
51 E2fsck now performs more extensive and careful checks of extended
52 attributes stored in the inode.
54 Mke2fs will always make sure that lost+found always has at least 2
55 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
57 The "ls" command in debugfs now supports the -p option, which causes
58 it to quote the filenames so that spaces or tabs in directory entries
59 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
60 Sourceforge Feature Request: #1201667)
62 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
65 The chattr program will return a non-zero exit code in case of
66 failures, and error messages can be suppressed with the -f option.
67 (Addresses-Red-Hat-Bugzilla: #180596)
69 Remove support for the legacy big-endian filesystem format which only
70 existed on extremely long-dead PowerPC kernels almost a decade ago.
72 Remove MASIX support from e2fsprogs.
74 Add I/O statistics reporting to e2fsck.
79 Factor out bitmap code in preparation for adding 64-bit new-style
82 Fix gcc -Wall warnings
84 Fix the pkg-config files so that private librares are specified in
87 Fix the libext2fs.texinfo manual so it builds with modern versions of
90 Silence the makefile from showing the awk command used to build the
92 Clean up the badblocks group so to make it more portable and robust.
94 Avoid using predictable filenames in /tmp in blkid's regression test
95 suite. Also remove bashism's in the regression test script.
97 A few library routines have been converted to support 64-bit block
98 numbers; in particular, the I/O manager functions, the test_io,
99 inode_io, and unix_io managers have all be converted to support 64-bit
102 Debugfs can now be extended for use by test programs. See
103 lib/ext2fs/extents.c for an example for how it can be used. The test
104 program links against the debugfs object files, and provides
105 additional commands by defining an auxiliary libss command table.
107 The lazy_bg filesystem feature, which was only used by developer's
108 testing, has been removed since it has been largely supplanted by
109 uninit_bg. This also simplifies the code.
112 E2fsprogs 1.40.11 (June 17, 2008)
113 =================================
115 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
116 percentage of reserved blocks. (Addresses Debian Bug: #452639)
118 Updated Spanish and Catalan translations.
120 Fixed various Debian packaging issues --- see debian/changelog for
121 details. (Addresses Debian Bugs: #483962, #483023)
123 Add detection for ZFS volumes to the libblkid library.
125 Fixed spelling mistakes, typos, and otherwise clarified man pages.
126 (Addresses Debian Bug: #486463)
131 Fix marginal C code in probe_lvm2() function to the blkid library more
132 portable for older compilers.
134 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
136 Fix ext2fs_swap{16,32,64} functions so they can be used by external
137 applications on big-endian machines. (Addresses Debian Bug: #484879)
140 E2fsprogs 1.40.10 (May 21, 2008)
141 ================================
143 When deciding whether or not to revalidate a blkid cache entry, if the
144 device's mtime is newer than the last time the cached entry was
145 validated, force a revalidation.
147 Fix a potential data corruption bug in e2fsck in the journal replay.
148 The chances of this is happening is extremely remote, especially the
149 default data=ordered or data=writeback modes. However, if a block
150 which has been journalled starts with the first four bytes 0xc03b3998,
151 when e2fsck replays the journal, those four bytes will be replaced
152 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
153 metadata to begin with those fatal 4 byte sequence, and unless
154 data=ordered mode is in use, data blocks are never journaled.
156 Updated German, Dutch, Sweedish, and Vietnamese translations.
161 Fixed various Debian packaging issues --- see debian/changelog for
164 Remove default sizes of types when cross compiling, since autoconf
165 2.50 can figure this out automatically now.
168 E2fsprogs 1.40.9 (April 27, 2008)
169 =================================
171 SuSE's security team audited uuidd and came up with a few minor
172 issues. None of them are serious given that uuidd runs setuid as a
173 unprivileged user which has no special access other than libuuid
174 directory, but it's good to get them fixed.
176 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
177 work correctly with in-inode extended attributes.
179 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
182 Debugfs will avoid using a pager if the standard output is not a tty.
184 Fix debugfs and tune2fs to correctly handle daylight savings time when
185 parsing a time string.
187 Fixed spelling mistakes, typos, and otherwise clarified man pages.
189 Fix fsck completion bars when multiple filesystems were being checked
190 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
191 #203323, Addresses Sourceforge Bug: #1926023)
193 Fix fsck so that progress information is sent back correctly when
194 multiple filesystems are being check and the output of fsck is being
195 redirected to a file descriptor. Also, include the device name (w/o
196 spaces) in the progress information sent back via a file descriptor.
197 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
200 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
202 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
203 signal to its child process.
205 Fix mke2fs's creation of are resize inode when there is a non-standard
206 s_first_data_block setting.
208 Fix bug in blkid when run by an unprivileged user; most devices were
209 not reported correctly. 9Addresses Launchpad Bug: #220275)
211 Mke2fs will not allow the logically incorect combination of
212 resize_inode and meta_bg, which had previously caused mke2fs to create
215 Fix fsck in German locales so that a 'j' means yes.
216 (Addresses Sourceforge Bug: #1947683)
222 Fixed various Debian packaging issues --- see debian/changelog for
225 Update valgrind options in test_script to work with valgrind 3.2.3
227 Update texinfo.tex to a much newer version from the FSF.
229 Remove bashism for configure script and from the lib/ss Makefile.
230 Addresses Sourceforge Bug: 1921969
232 Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
234 Fix build system so that if texinfo is not installed, it won't print a
235 (harmless) error message.
238 E2fsprogs 1.40.8 (March 13, 2008)
239 =================================
241 Fixed e2image -I so it works on image files which are larger than 2GB.
243 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
244 the size is larger than the number of blocks found in the inode, don't
245 try to allocate extra empty blocks at the end of the directory to make
246 up the difference; there's no point to doing that. In addition, if
247 the size is not a multiple of a blocksize, always fix it.
249 E2fsck handled a pass 2 "should never happen error" by not giving
250 enough information and then core dumping. Unfortunately, it was all
251 too easy to trigger the "should never happen" situation if a
252 directory's inode size was not correct. This has been fixed, but
253 e2fsck has also been taught how to handle this situation more
254 gracefully, by simply removing the inode hash tree information, so
255 that it can be rebuilt again after e2fsck's pass 3. (Addresses
256 Launchpad Bug: #129395)
258 Resize2fs had a bug resizing large inodes with extended attributes
259 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
260 completely on big-endian systems such as PowerPC. The bug should be
261 completely fixed now. Yay for regression test suites. (Addresses Red
262 Hat Bugzilla: #434893)
264 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
265 translations. Many thanks to Philipp Thomas from Novell for stepping
266 up to become the new German translation maintainer! (Addresses Debian
267 Bugs: #302512, #370247, #401092, #412882).
269 When e2fsck is clearing a corrupt inode's HTREE directory information,
270 make it clear that it is just clearing the HTREE information, not the
273 Fixed spelling mistakes, typos, and otherwise clarified man pages.
278 Add new functions, ext2fs_dblist_get_last() and
279 ext2fs_dblist_drop_last(), which allows the caller to examine the last
280 directory block entry added to the list, and to drop if it necessary.
282 Fixed a portability problem in libblkid with DJGPP.
284 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
285 to Philipp Thomas for pointing this out.
287 If the info files are not built, change "make install" so it doesn't
288 fail with an error code.
291 E2fsprogs 1.40.7 (February 28, 2008)
292 ====================================
294 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
295 depreciate the -s option, since it can result in filesystems which
296 e2fsck can't fix easily. There are very good reasons for wanting to
297 disable sparse_super; users who wants to turn off sparse_super can use
298 debugfs. (Addresses Sourceforge Bug: #1840286)
300 Add missing options to mke2fs's usage message. (Addresses Sourceforge
303 Fix bug in resize2fs when large (greater than 128 byte) inodes are
304 moved when a filesystem is shrunk; it was only moving the first 128
305 bytes, so extended attributes were not getting moved. (Addresses Red
306 Hat Bugzilla: #434893)
308 E2fsck now prints an explicit message when the bad block inode is
309 updated, to avoid confusion about why the filesystem was modified.
310 (Addresses Sourceforge Bug: #756460)
312 Allow mke2fs and tune2fs manipulate the large_file feature.
313 Previously we just let the kernel and e2fsck do this automatically,
314 but e2fsck will no longer automatically clear the large_file feature.
315 It still isn't really necessary to worry about this feature flag
316 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
319 Suppress message about an old-style fstab if the fstab file is empty.
320 (Addresses Debian Bug: #468176)
322 Fix (really minor) bug in debugfs's find_free_block so it avoids
323 reporting a free block more than once if there are too few free blocks
324 in the filesystem. (Addresses Sourceforge Bug: #1096315)
326 Change e2fsck to no longer clear the LARGE_FILES feature flag
327 automatically, when there are no more > 2GB files in the filesystem.
328 It's been almost a decade since there have been kernels that don't
329 support this flag, and e2fsck clears it quietly without telling the
330 user why the filesystem has been changed.
332 Fix bug which could cause libblkid to seg fault if a device mapper
333 volume disappears while it is being probed. (Addresses RedHat
336 Inhance e2fsck's reporting of unsupported filesystem feature flags.
337 (Addresses Sourceforge Feature Request: #1175808)
339 Fix option syntax in dumpe2fs for explicit superblock and blocksize
340 parameters. What was currently documented in the man page has been
341 broken for some time, due to getopt() implementation changes. The
342 option sytax has been changed to one which is can be more portable
343 supported and which is consistent with the format for extended options
344 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
346 Add support to tune2fs to clear the resize_inode feature. This
347 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
349 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
352 Add support for setting RAID stride and stripe-width via mke2fs and
353 tune2fs. Teach dumpe2fs to print the RAID parameters.
355 Add support for setting new superblock fields to debugfs's
358 Add support for printing "mostly-printable" extended attributes in
361 Add support for the -M option to fsck, which causes it to ignore
364 Fix uuidd so that it creates the pid file with the correct pid number.
365 (Addresses Sourceforge Bug: #1893244)
367 Fix various gcc -Wall warnings.
369 Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
371 Fixed spelling mistakes, typos, and otherwise clarified man pages.
372 (Addresses Sourceforge Patch: #1399325)
378 Fixed various Debian packaging issues --- see debian/changelog for
379 details. (Addresses Debian Bug: #466929)
381 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
382 partially filled-in filesystem object on an error, so that e2fsck can
383 print more intelligent error messages.
385 Add a new function e2p_edit_feature2() which allows the caller to
386 specify which feature flags are OK to set or clear, and which returns
387 more specific information about feature flags which are not allowed to
390 Set the C locale in the test_script driver since it uses [A-Za-z].
391 (Addresses Sourceforge Bug: #1890526)
393 Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
396 Change configure.in to avoid using the 'dc' command unless it is
397 absolutely needed. (i.e., when using parsing a WIP-style version
398 number) (Addresses Sourceforge Bug: #1893024)
400 Add portability checks to support compilation under DJGPP.
402 Update to the latest samba tdb code before the LGPLv3 change, which
403 fixes a realloc() leak on failure.
405 Fix memory leak in ext2fs_alloc_block().
407 Fix makefile dependency issues for various install targets.
408 (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
410 Improve descriptions for the r_move_itable and r_resize_inode tests.
413 E2fsprogs 1.40.6 (February 9, 2008)
414 ===================================
416 Add support for returning labels for UDF filesystems in the blkid
419 Fix bug in the blkid library where cached filesystems was not being
420 flushed when opening USB devices returned the error ENOMEDIUM.
421 (Addresses Debian Bug: #463787)
423 Added logic to the blkid library to automatically choose whether a
424 filesystem should be mounted as ext4 or ext4dev, as appropriate.
426 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
428 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
429 configured with --enable-jbd-debug.
431 Document the BLKID_FILE environment variable in the libblkid man page
436 Update e2fsprogs translation template and Vietnamese and Czech translations
438 Fixed various Debian packaging issues --- see debian/changelog for
439 details. (Addresses Debian Bugs: #436058)
441 Don't try to create $DESTDIR/etc/init.d as part of make install as we
442 don't install the init.d script (and it's not the recommended way to
443 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
445 Use thread local storage to fix a theoretical race condition if two
446 threads try to format an unknown error code at the same time in the
450 E2fsprogs 1.40.5 (January 27, 2008)
451 ===================================
453 Fix a potential overflow big in e2image if the device name is too
456 Mke2fs will now create new filesystems with 256 byte inodes and the
457 ext_attr feature flag by default. This allows for much better future
458 compatibity with ext4 and speeds up extended attributes even on ext3
461 Teach e2fsck to ignore certain "safe" filesystem features which are
462 set automatically by the kernel. Having the kernel set features
463 automagically behind the user's back is a bad idea, and we should try
464 to break the kernel of this habit, especially for the newer ext4
465 feature flags. But for now, we will try to avoid needless full checks
466 which can annoy users who are doing fresh installs.
468 Add support in tune2fs and mke2fs for making a filesystem as being "ok
469 to be used with test kernel code". This will be needed for using test
470 filesystems with the latest ext4 kernel code.
472 Change e2fsck -fD so that it sorts non-htree directories by inode
473 numbers instead of by name, since that optimizes performances much
474 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
476 If e2image fills the disk, fix it so it exits right away instead of
477 spewing large numbers of error messages.
478 (Addresses-Sourceforge-Feature-Request: #606508)
480 If ftruncate64() is not available for resize2fs, let it use ftrucate()
481 instead, but have it check to see if the size would get truncated, and
482 skip calling ftruncate in that case.
484 Add support for detecting HFS+ filesystems in the blkid library.
486 Add supprt in the blkid library for ext4/ext4dev filesystems.
488 Fix a bug in blkid where it could die on a floating point exception
489 when presented with a corrupt reiserfs image.
491 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
492 such that UUID string is a fixed length.
494 Add sample python bindings for the uuid library to the contrib
495 directory. (Addresses-Sourceforge-Patches: #778817)
497 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
498 will work with large files. (Addresses Sourceforge Feature Request:
499 #1257500 and Sourceforge Support Request: #1253511)
501 Allow the debugfs 'undel' command to undelete an inode without linking
502 it to a specific destination directory, since this might require
503 allocating blocks that could overwrite some yet-to-be-recovered
504 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
506 Update Swedish translations from the Translation Project.
511 Fix configure handling of --sbindir (which should rarely be used, but
512 someone did complain, so let's fix it). (Addresses Sourceforge Bug:
515 Updated e2fsprogs.spec file to include a new uuidd package
517 Use pkg-config to determine where to find the devmapper library so we
518 can find out where it is located on different distributions.
520 Fix Makefile race so that "make -j3 distclean" works correctly
522 Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
523 especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
526 Fixed spelling mistakes, typos, and otherwise clarified man pages.
528 Fixed various Debian packaging issues --- see debian/changelog for
529 details. (Addresses Debian Bugs: #459403, #459475, #459614)
531 Remove the --enable-dynamic-static configure option, and build e2fsck
532 dynamically by default. If the user wants e2fsck.static, he/she will
533 need to build it via "make -C e2fsck e2fsck.static"
535 Fix various build warnings due to missing prototypes.
536 (Addresses Sourceforge Patch: #1861663, #1861659)
539 E2fsprogs 1.40.4 (December 31, 2007)
540 ====================================
542 Improve time-based UUID generation. A new daemon uuidd, is started
543 automatically by libuuid if necessary. This daemon is setuid to allow
544 updates to /var/lib/libuuid, so the clock sequence number can be
545 stored and so if the clock is set backwards, it can be detected.
546 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
549 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
550 superblocks. This avoids e2fsck from concluding that a full
551 filesystem check is required before backing up the superblock due to
552 changes in the feature flags. (Addresses Debian Bug: #454926)
554 Fix fsck to only treat the '#' character as a comment at the beginning
555 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
556 will cause fsck to issue an bogus warning message.
557 (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
559 Format control characters and characters with the high eighth bit set
560 when printing the contents of the blkid cache, to prevent filesystems
561 with garbage labels from sending escape sequences to the user's screen
562 that might, for example place it in graphics mode. (Addresses Ubuntu
565 Fix sign-extension problem on 64-bit systems in in the com_err
566 library. (Addresses Sourceforge Bug: #1809658)
568 Avoid division by zero error when probing an invalid FAT filesystem in
569 the blkid library. (Addresses Sourceforge Bug: #1831627)
571 Update Dutch, Polish, and Vietnamese translations from the Translation
572 Project. Remove the Rwandan translation upon advice of the
578 Fix the libss "make check" regression test so that it works if the
579 current directory is not in the user's path or if the libss shared
580 library is not installed. (Addresses Sourceforge Bug: #1848974)
582 Fixed spelling mistakes, typos, and otherwise clarified man pages.
583 (Addresses Debian Bugs: #444883, #441872)
585 Fixed various Debian packaging issues --- see debian/changelog for
586 details. (Addresses Debian Bugs: #437720, #451172, #458017)
588 Fix build failure on non-Linux/non-Hurd/non-Masix systems.

591 Fix Hurd portability issues. (Addresses Debian Bug: #437720)
594 E2fsprogs 1.40.3 (December 5, 2007)
595 ===================================
597 Fix a potential security vulnerability where an untrusted filesystem
598 can be corrupted in such a way that a program using libext2fs will
599 allocate a buffer which is far too small. This can lead to either a
600 crash or potentially a heap-based buffer overflow crash. No known
601 exploits exist, but main concern is where an untrusted user who
602 possesses privileged access in a guest Xen environment could corrupt a
603 filesystem which is then accessed by the pygrub program, running as
604 root in the dom0 host environment, thus allowing the untrusted user to
605 gain privileged access in the host OS. Thanks to the McAfee AVERT
606 Research group for reporting this issue. (Addresses CVE-2007-5497.)
608 Fix hueristics in blkid which could cause a disk without partitions to
609 be incorrectly skipped when a loopback device is present. (Addresses
610 Red Hat Bugzilla #400321.)
612 Fix e2image so that in raw mode it does not create an image file which
613 is one byte too large.
615 Change mke2fs's usage message so it recommends the preferred -E option
616 instead of the deprecated -R option.
618 Enhance the blkid library so it will recognize squashfs filesystems.
619 (Addresses Red Hat Bugzilla #305151.)
621 Enhance e2fsck so it will force the backup superblocks to be backed up
622 if the filesystem is consistent and key constants have been changed
623 (i.e., by an on-line resize) or by e2fsck in the course of its
626 Enhance blkid's detection of FAT filesystems; so that USB disks with
627 only a single bootable partition will not get missed.
629 E2fsck will no longer mark a filesystem as invalid if it has time
630 errors (i.e., if superblock mount time or last write time is in the
631 future) and the user refuses to fix the problem.
633 The Ubuntu init scripts don't properly set the system time correctly
634 from hardware clock if the hardware clock is configured to tick local
635 time instead of GMT time. Work around this as best as we can by
636 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
637 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
640 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
641 Hat Bugzilla #151533.)
643 Fix e2fsck so that if the superblock is corrupt, but still looks
644 vaguely like an ext2/3/4 superblock, that it automatically tries to
645 fall back to the backup superblock, instead of failing with a hard
648 Make the e2fsprogs program more robust so that they will not crash
649 when opening a corrupt filesystem where s_inode_size is zero.
651 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
652 arguments are detected as such and the parse error is reported to the
653 user. (Addresses Debian Bug #435381.)
655 Change e2fsck so it will not complain if a file has blocks reallocated
656 up to the next multiple of a system's page size.
658 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
659 about (valid) filesystems where the inode table extends to the last
660 block of the block group. (Addresses Red Hat Bugzilla #214765.)
662 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
663 allocating inode tables for some relatively rare odd disk sizes.
664 (Addresses Red Hat Bugzilla #241767.)
666 Add Catalan translation and update Dutch and Swedish translations
667 from the Translation Project.
669 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
670 still had an issue when trying to figure out whether we need to
671 byte-swap fast symlinks that contained extended attributes.
673 Fixed spelling mistakes, typos, and otherwise clarified man pages.
674 (Addresses SourceForge Bug #1821333.)
680 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
682 Add "make check" to the RPM spec file
684 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
685 works correctly when the prefix is not the root directory.
687 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
688 clena up after themselves by deleting the test.img temporary file
689 after completing the test.
691 Fixed a corner case bug ext2fs_unlink() when trying to delete the
692 first directory entry in a directory block and the last directory
693 entry in the previous directory block is not in use. Fortunately
694 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
695 places where it is extremely unlikely to run into this corner case.
697 Fix missing dependency which would cuase parallel builds to fail.
698 (Addresses Sourceforge Bug #1842331.)
700 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
701 calling open(O_CREATE) with a missing mode parameter.
703 Fix the test_ss.c in lib/ss so it can be used as an example
704 application program for the library as well as a regression test
707 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
708 are properly passed back up through the call stack.
710 E2fsprogs 1.40.2 (July 12, 2007)
711 ================================
713 A recent change to e2fsck_add_dir_info() to use tdb files to check
714 filesystems with a very large number of filesystems had a typo which
715 caused us to resize the wrong data structure. This would cause a
716 array overrun leading to malloc pointer corruptions and segfaults.
717 Since we normally can very accurately predict how big the the dirinfo
718 array needs to be, this bug only got triggered on very badly corrupted
721 Fix a bug in e2fsck which caused it to incorrectly salvange
722 directories when the last entry's rec_len is bogusly too big. This
723 resulted in a nonsense filesystem corruption to be reported, and
724 required a second run of e2fsck to fully fix up the directory.
726 Update tune2fs man page to include more discussion of reserved blocks
727 (Addresses Launchpad bug #47817)
729 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
733 E2fsprogs 1.40.1 (July 7, 2007)
734 ===============================
736 Fix bug which could cause libblkid to loop forever. When revalidating
737 a partition where there is obsolete information in /etc/blkid.tab, we
738 end up freeing a the type tag without clearing dev->bid_type, causing
739 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
741 The Turkish translation has a bug in it where it has the translation
742 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
743 @E, recursively, forever, until the stack fills up and e2fsck core
744 dumps. We fix this by making e2fsck stop @-expansions after a
745 recursive depth of 10, which is far more than we need.
746 (Addresses Sourceforge Bug: #1646081)
748 Compile the default mke2fs.conf into mke2fs program. People are
749 getting surprised by mke2fs creating filesystems with different
750 defaults than earlier versions of mke2fs if mke2fs.conf is not
751 present. So we now create a built in version of mke2fs.conf file
752 which is used by mke2fs if the /etc/mke2fs.conf is not present.
753 (Addresses SourceforgeBug: #1745818)
755 Improve the config/parse_types.sh helper script. Fix a potential
756 security problem if e2fsprogs is built as root (as Gentoo does!). In
757 addition fix the script and how it is called from the configure script
758 so that it does the right thing when cross-compiling. (Fixes Gentoo
761 Update Vietnamese, French, and Dutch PO files from the Translation
762 Project. Also created a new e2fsprogs.pot file for translator.
764 Fix bogus strip permission errors when building under Debian. When
765 building the e2fsprogs dpkg's, the dh_strip command emits a large
766 number of error messages caused by the permissions not being right.
767 So run dh_fixperms before running dh_strip.
772 Add new function: profile_set_default(). This function sets the value
773 of the pseudo file "<default>". If the file "<default>" had
774 previously been passed to profile_init(), then def_string parameter
775 will be parsed and used as the profile information for the "<default>"
778 Fix mk_cmds's error reporting so that it is unambiguous that it is the
779 mk_cmds script which is generating the error. (Obviates Gentoo patch:
780 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
782 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
783 priority" environment variable that overrides all others, where as
784 LANG is the lowest priorty environment variable. If LC_ALL is set, it
785 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
786 the all the rest are set. This will assure that the locale when
787 running the test suites is the "C" locale. (Obviates Gentoo patch:
788 e2fsprogs-1.38-tests-locale.patch)
791 E2fsprogs 1.40 (June 29, 2007)
792 ==============================
794 Fix divide by zero error in blkid's NTFS probing logic.
796 Add new blkid -g option which causes the blkid cache to be garbage
799 Fix a bug in libblkid which could cause the internal field bid_type to
800 become corrupted. Fortunately bid_type isn't used much, and bid_label
801 and bid_uuid is only used by debugging code, so the impact of this bug
804 Mke2fs will now store the RAID stride value when a filesystem is
805 created with a requested RAID stride, and then use it automatically in
808 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
809 isn't too big. In some cases Lustre users have tried specifying an
810 inode size of 4096 bytes, while keeping an inode ratio of one inode
813 Improve sanity check in e2fsck's algorithm for finding a backup
814 superblock, so that it won't accidentally find a superblock that was
815 located in the journal, and then later reject it as being not a valid
818 Fix e2fsck get_size logic so that it will work with the Linux floppy
819 driver. The Linux floppy driver is a bit different from the other
820 block device drivers, in that if the device has been opened with
821 O_EXCL, it disallows another open(), even if the second open() does
822 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
824 Fix error checking of badblock's last-block and start-block arguments.
825 (Addresses Debian Bug: #416477)
827 Fix e2fsck so that it doesn't overwrite the backup superblocks when
828 recovering a journal until the master superblock has been confirmed as
831 Change the blkid library to be much more paranoid about concluding
832 that a partition contains an NTFS filesystem, and fetch the UUID and
833 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
836 Factor out the code which sets the default journal size and move it
839 Enhance e2fsck so it will recreate the ext3 journal if the original
840 journal inode was cleared to due it being corrupt after finishing the
843 Fix e2fsck so that it updates the journal inode if it is corrupted and
844 the backup journal information from the superblock was successfully
845 used to recover the filesystem.
847 Fix e2fsck so that it checks all of the blocks in the journal inode
848 for validity. The original code only checked the direct blocks to
849 make sure the journal inode was sane. Unfortunately, if some or all
850 of the indirect or doubly indirect blocks were corrupted, this would
853 Add support in blkid to detect LUKS encrypted partitions.
855 Add extra sanity checks for extended attributes in the case where the
856 size is zero but the offset is very large.
858 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
859 and ext2fs_get_next_inode_full().
861 Clarify the copyright licenses used by the various libraries in
862 the top-level COPYING file (Red Hat Bugzilla: 166058)
864 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
866 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
868 Remove check in e2fsck which requires EA's in inodes to be sorted;
869 they don't need to be sorted, and e2fsck was previously wrongly
870 clearing unsorted EA's stored in the inode structure.
872 Allow mke2fs or tune2fs to create a substantially larger journal (up
873 to 10,240,000 blocks).
875 Fix MD superblock detection, and make sure the correct UUID is
876 reported from the MD superblock.
878 Fix a signed vs. unsigned bug in debugfs.
880 Enhance debugfs's date parser so that it accepts integer values.
882 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
883 file with multiply claimed blocks is hard linked. or not at all if the
884 root directory contains shared blocks
886 Enhance debugfs so it can modify the block group descriptors using the
887 command set_block_group_descriptor.
889 Improve e2fsck's reporting of I/O errors so it's clearer what it was
890 trying to do when an error happens
892 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
893 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
894 #232663 and LTC Bugzilla: #27634)
896 Fix potential file descriptor leak in ext2fs_get_device_size() in an
899 Add libreadline.so.5 support to libss.
901 Impove badblocks -n/-w exclusive usage message.
903 Fix dump_unused segfault in debugfs when a filesystem is not open
905 Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
907 Allow the debugfs lcd command to work w/o a filesystem being open.
908 (Addresses LTC Bugzilla #27513)
910 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
911 field on the first pass.
913 Fix e2fsck to set the file type of the '..' entry when connecting
914 a directory to lost+found. (Addresses Lustre Bug: #11645)
916 Enhance e2fsck to recover directories whose modes field were corrupted
917 to look like special files. This is probably only useful in
918 artificial test cases, but it will be useful if we ever do the "inodes
919 in directory" idea for ext4.
921 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
924 Fix resize2fs parsing of size parameter (in sector units). This was
925 actually a bug in libe2p's parse_num_blocks() function. When handling
926 the 's' suffix, it was ignoring the blocksize information passed in
927 from the caller and always interpreting the number in terms of a 1k
928 blocksize. (Addresses Debian Bug: #408298)
930 There was a floating point precision error which could cause e2fsck to
931 loop forever on really big filesystems with a large inode count.
932 (Addresses Debian Bug: #411838)
934 Fix memory leak in ext2fs_write_new_inode()
936 Add support for using a scratch files directory to reduce e2fsck's
937 emory utilization on really big filesystems. This uses the TDB
938 library. See the [scratch_files] section of the e2fsck.conf man page
941 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
942 platform (Addresses Debian Bug: #397044)
944 Add explanatory message to badblocks that -n and -w are mutually exclusive
945 (Addresses Debian Bug: #371869)
947 Allow debugfs and dumpe2fs to support fs features under development.
949 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
950 ext2fs_open() , which allows application to open filesystes with features
951 which are currently only partially supported by e2fsprogs.
953 Allow unix_io to support offsets greater than 2G (Addresses
954 SourceForge Bug: #1547922)
956 Fixed overflow and signed/unsigned problems caused by the number of
957 blocks or inodes exceeding 2**31 or being close to 2**32-1.
959 Add support for unsigned directory hash calculations with hints in the
960 superblock to fix cross-architectural portability for htree
961 directories with filenames where the high 8th bit is set. (Addresses
964 Fix resize2fs so that it gives user-intelligible error messages if the
965 filesystem or the kernel does not support on-line resizing.

968 Require mke2fs -F -F for really dangerous operations, since -F is
969 needed for less dangerous operations such as creating filesystems
970 images in regular files, or creating filesystems on whole block
971 devices. These relatively innocuous usages should NOT be confused
972 with running mke2fs on an apparently-mounted or in-use filesystem.
974 Allow the default inode size to be specified into the mke2fs.conf
977 Make the smallest default journal size is big enough so that on-line
978 resizing should always work.
980 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
983 Fix debugfs coredump when lsdel is run without an open filesystem
984 (Addresses Debian Bug: #378335)
986 Fix debugfs display bug us that bytes that have the high bit set are
987 displayed as "ec" instead of "ffffffec".
989 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
991 Device mapper scanning wasn't working in the blkid library because the
992 pathnames had an extra "/dev" when they were being probed.
994 Add GFS/GFS2 support to the blkid library.
996 Fix blkid support of empty FAT filesystem labels.
998 Avoid recursing forever (or for a long time) when the blkid library
999 searches for a device and there are symlinks to directories in /dev.
1001 Avoid unaligned halfword access in blkid when accessing FAT
1002 superblocks, as this will cause Sparc/Solaris systems to throw a

1006 the static link libraries for e2fsck.static if devmapper is enabled.

1009 Improve the (non-installed, for experts only) findsuper program by
1010 printing the uuid and label from the superblocks, as well as the
1011 starting and ending offsets of the filesystem given the information in
1012 the superblock. Omit by default printing superblocks that are likely
1013 found in located in an ext3 journal unless an explicit -j option is
1016 Updated Spanish, French and Dutch translations and added Catalan
1017 translation. (Addresses Debian bug: #411562)
1019 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
1020 determining a partition's size, since binary searching to determine
1021 the device doesn't work on FreeBSD.
1023 Documentation about UUID's is available in enough places, and it's
1024 awkward to deal with debian-legal's insanities. So I'm caving in the
1025 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
1026 don't have do the dfsg tarball. Also remove the rule that only tried
1027 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
1028 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
1030 Fix the info-dir line so that the menu name does not contain a .info
1031 prefix. First of all, it's ugly, secondly, it causes the install-info
1032 command to fail to remove the com_err info file from the
1033 /usr/share/info/dir file when the comerr-dev package is removed and
1034 purged. (Addresses Debian Bug: #401711)
1036 Fixed spelling mistakes, typos, and otherwise clarified man pages.

1051 (Addresses Sourceforge Bug: #1565561)
1053 Remove unused variables and other lint/gcc -Wall cleanups
1055 Add check to ext2fs_get_device_size() so it will return EFBIG for for
1056 filesystems contained in regular files where the filesystem image size
1057 is returned by stat64().
1059 Set local environment variables to C so mk_cmds and compile_et always
1060 work. (Addresses SourceForge Bug: #1532177)
1062 Added the 64-bit byte swapping function ext2fs_swab64().
1064 Added two new helper functions to prevent 2**31/2**32-1 overflow
1065 problems: ext2fs_div_ceil() and e2p_percent().
1067 Create new ext2fs library inline functions ext2fs_group_first_block()
1068 and ext2fs_group_last_block() in order to calculate the starting and
1069 ending blocks in a block group.
1071 Create the generated files read-only to remind developers not to edit them.
1073 Add support for autoconf 2.60 (with backwards compatibility for older
1074 versions of autoconf).
1076 Added an "make rpm" target to top-level Makefile
1078 Added various FreeBSD portability fixes.
1080 Exclude mercurial files from the RPM build tree to speed up copy/build.
1082 Use root_sysconfdir to define the locations of mke2fs.conf and
1083 e2fsck.conf instead of using a hard-coded /etc pathname.
1085 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
1087 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
1089 If diff -u is supported, use it to report test failures.
1091 Updates/improvements to RPM spec file
1093 Add on-disk format definitions for the following new features:
1094 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
1095 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
1096 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
1098 Add a new make target "checked-failed" in the tests directory which
1099 reruns any failed tests
1101 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
1103 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
1104 pointer dereferences, memory leaks, etc. None were security-criticial
1107 Fix up usage and decrement error messages in the test_icount program
1109 Add debugging code to the com_err library; if the environment variable
1110 COMERR_DEBUG is set to 1, print out debugging messages as error tables
1111 are added and removed from the com_err library. If the
1112 COMERR_DEBUG_FILE environment variable is set (and the process is not
1113 setuid) the debugging messages may be redirected to a file.
1115 Change all of the e2fsprogs programs to use the newer add_error_table()
1116 and remove_error_table() interfaces instead of the much older
1117 initialize_*_error_table() function.
1119 Add TDB support into the ext2fs library. This allows us to have a
1120 guaranteed library we can count on always being present so we can
1121 store data in an on-disk database.
1123 Add support for using TDB to store the icount data, so we don't run out
1124 of memory when checking really large filesystems.
1126 Change the regression test suite so that it skips empty test directories.
1128 Define the l_i_iversion field in ext2_inode. The l_i_version field is
1129 now defined from the old l_i_reserved1 field in the ext2 inode. This
1130 field will be used to store high 32 bits of the 64-bit inode version
1133 Add Makefile production rule for e2fsprogs.spec in case it gets
1136 Add new function profile_get_uint() to allow for a clean way to fetch
1137 unsigned integers from the context.
1139 Add test to make sure the ext2 superblock structure is 1024 bytes.
1141 Fix typo in name of f_dup4 regression test
1143 Add new function blkid_gc_cache() which performs a garbage collection
1144 pass on the /etc/blkid.tab file.
1146 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
1147 general, only e2fsck (after the filesystem is clean), tune2fs, and
1148 resize2fs should change the backup superblocks by default. Most
1149 callers of ext2fs_open() should not be touching any superblock fields
1150 which require the backups to be touched.
1152 Add new function to libext2fs, ext2fs_default_journal_size(), which
1153 returns the default journal size.
1156 E2fsprogs 1.39 (May 29, 2006)
1157 =============================
1159 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
1160 between 2**31 and 2**32 blocks.
1162 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
1163 configure the filesystem features, blocksize, and inode_ratio for
1164 different filesystem types.
1166 Mke2fs will now create filesystems hash trees and on-line resizing
1167 enabled by default, based on the new /etc/mke2fs.conf file.
1169 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
1170 filesystem device node in exclusive mode to prevent accidents by
1171 system administrators. In the case of resize2fs and mke2fs, it will
1172 only use exclusive mode if the filesystem is not mounted.
1174 Fixed a bug in mke2fs which caused it to to fail when creating the
1175 resize inode for large filesystems. (Addresses Debian Bug #346580)
1177 When allocating space for the RAID filesystems with the stride
1178 parameter, mke2fs will now place each portion of the group's inode
1179 table right up after the superblock (if present) in order to minimize
1180 fragmentation of the freespace.
1182 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
1183 efficiently by writing the inode and block bitmaps in one pass, thus
1184 reducing the number of disk seeks required.
1186 Add support for on-line resizing to resize2fs.
1188 Fix blkid library so that logic to determine whether or not a device's
1189 cached information in /etc/blkid.tab needs to be verified or not
1190 doesn't get confused by a system clock which is insane (for example,
1191 if the battery is dead on a Macintosh running PPC Linux. (Addresses
1192 Red Hat Bug: #182188)
1194 The blkid library will now store the UUID of the external journal used
1195 by ext3 filesystems, so that in the future, the userspace mount binary
1196 can use this to find the location of the external journal and pass
1197 this information to the kernel.
1199 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
1200 control how various options should be handled. See the e2fsck.conf
1201 man page for more details. (Addresses Debian Bug: #150295)
1203 E2fsck now prints an explanatory message when delaying a filesystem
1204 check when the system is running on battery. (Addresses Debian Bug:
1207 E2fsck will detect if the superblock's last mount field or last write
1208 field is in the future, and offer to fix if so. (Addresses Debian Bug
1209 #327580) These problems will be fixed automatically in preen mode
1210 since Debian's boot sequence bogusly doesn't set the time correctly
1211 until potentially very late in the bootup process, and this can cause
1212 false positives which will cause users' systems to fail to boot.
1213 (Addresses Debian Bugs #343662 and #343645)
1215 E2fsck now checks to see if the superblock hint for the location of
1216 the external journal is incorrect, and if so, offer to update it.
1217 (Addresses Debian Bug: #355644)
1219 Fix e2fsck from segfaulting on disconnected inodes that contain one or
1220 more extended attributes. (Addresses Debian Bug: #316736, #318463)
1222 E2fsck will stop and print a warning if the user tries running a
1223 read/write badblocks test on a read-only mounted root filesystem.
1225 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
1226 C. Thompson for pointing these out; they were originally found using
1229 When resizing a file containing a filesystem, resize2fs will expand or
1230 truncate a file as necessary. (Addresses Debian Bug: #271607)
1232 Resize2fs will now automatically determine the RAID stride parameter that
1233 had been used to create the filesystem, and use that for newly created
1234 block groups. The RAID stride parameter may also be manually specified
1235 on the command line using the new -S option to resize2fs.
1237 Fix mke2fs so that it correctly creates external journals on
1238 big-endian machines (such as a S/390).
1240 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
1241 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
1242 Chambraud for pointing this out.)
1244 Dumpe2fs will now print the size of the journal (if present).
1246 Fix debugfs's set_inode_field command so it can properly set the frag,
1247 fsize, uid_high, gid_high, and author fields in the inode instead of
1248 silently failing, and so that setting the i_size actually sets i_size
1251 Add a new debugfs command, set_current_time, which sets fs->now so
1252 that regression test suites can repeatedly modify the filesystem's
1255 Fix a bug in debugfs's icheck which would incorrectly report the owner
1256 of an extended attribute block.
1258 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
1259 print a usage message when an illegal option character is given.
1261 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
1262 so it won't core dump. (Addresses SourceForge bug #1424311)
1264 Fix mklost+found so that it creates a full-sized directory on
1265 filesystems with larger block sizes.
1267 Fix a file descriptor leak in blkid library.
1269 Fix a display bug in "badblocks -sv" so that the done message properly
1270 clears the block number at the end of the test. (Addresses Debian Bug
1273 Allow fractional percentages to the -m option in mke2fs and tune2fs
1274 (Addresses Debian Bug: #80205)
1276 Use fstat/fstat64 in getsize.c if the the target is a regular file,
1277 instead of attempting to do a binary search. Fix some fd leaks in
1280 Add support for device mapper library to the blkid library to ensure
1281 that the "best" (i.e., leaf) device is probed by the blkid library.
1283 Fix the blkid library so that it notices when an ext2 filesystem is
1286 Improve the blkid's library VFAT/FAT detection; it now understands
1287 labels stored in the root directory, and is more paranoid about
1288 checking the FAT superblock values.
1290 Fixed a fd leak in the uuid library which was causing problems for the
1291 LVM tools. (Addresses Debian Bug: #345832)
1293 Add support for the reiser4 and software suspend partitions to the
1294 blkid library. Also add support for extract the label from iso9660
1297 Fix a compile_et bug which miscount the number of error messages if
1298 continuations are used in the .et file.
1300 Add extra sanity checks to protect users from unusual cirucmstances
1301 where /etc/mtab may not be sane, by checking to see if the device is
1302 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
1305 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
1306 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
1308 Fix use-after-free bug in e2fsck when finishing up the use of the
1309 e2fsck context structure.
1311 Fixed spelling mistakes, typos, and otherwise clarified man pages and
1312 documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

1317 details. (Addresses Debian Bugs #317862, #320389, #290429, #310950,
1318 #310428, #330737, #330736, #329074, #356293, #360046, #366017, #364516,
1325 Update config.guess and config.sub to latest version (2006-02-23) from
1328 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
1329 Bugs: #360661, #360317)
1331 Fixed the Makefile so that they work correctly on newer versions of
1332 GNU make (i.e., 3.81).
1334 Add valgrind support to the regression test suites, and eliminate
1335 false positives from valgrind.
1337 Add a regression test suite for the blkid library.
1339 Fix a fencepost error in resize2fs caught by valgrind.
1341 Fix compiler warnings about missing memcpy prototypes.
1343 We no longer have the sparc assembly code in the header file any more,
1344 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
1345 break compiles on the sparc architectures when using gcc.
1347 In the libext2fs library, add the new field fs->now which if non-zero
1348 is used instead of the system time when setting various filesystem
1349 fields (last modified time, last write time, etc.)
1351 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
1352 ext2fs.h which is needed since the inline functions use memcpy().
1353 (Addresses Sourceforge Bug #1251062)
1355 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
1356 the build system when building files in the util directory which are
1357 needed during the build process. This avoids potential problems when
1358 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
1359 are not recognized as valid by the host compiler. (Addresses
1360 Sourceforge Bug #1261547)
1362 Clean up the blkid library by making the superblock and generic i/o
1363 functions to be more generic. Clean up interface to the probe
1364 function, and fix memory leak. Finallly, remove an unneeded reference
1365 to probe.h in the lib/blkid/resolve.c
1367 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
1368 of invalid block #'s.
1370 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
1371 indicate that the the function read/writes the memory location.
1373 Fix various gcc -Wall complaints.
1375 Add a dependency to make sure that the subdirectories are created
1376 before creating all of the object files, in order to address parallel
1377 build problem in the library Makefiles. (Addresses Sourceforge Bug:
1380 Add $(LDFLAGS) to the command line argument when generating an ELF or
1381 Solaris shared library, to allow cross-compile and other builds that
1382 might need to specify -L paths to needed libraries. (Addresses
1383 Sourceforge Bug #1261549)
1385 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
1386 intended for testing purposes. It allows an ext2/ext3 developer to
1387 create very large filesystems using sparse files where most of the
1388 block groups are not initialized and so do not require much disk
1389 space. Eventually it could be used as a way of speeding up mke2fs and
1390 e2fsck for large filesystem, but that would be best done by adding an
1391 RO_COMPAT extension to the filesystem to allow the inode table to be
1392 lazily initialized on a per-block basis, instead of being entirely
1393 initialized or entirely unused on a per-blockgroup basis.
1395 Fix backwards compatibility so e2fsprogs will better compile on Linux
1398 Make test scripts more robust against locale-related environment variables
1400 Fix type warning problem with sizeof() in ext2fs_open2().
1402 Fix type warning problem with time_t in debugfs.
1405 E2fsprogs 1.38 (June 30, 2005)
1406 ==============================
1408 Fix blkid's test programs (built with "make check") compile correctly
1409 even without "configure --enable-blkid-debug".
1411 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
1412 type aliasing rules on newer gcc compilers. (Addresses Red Hat
1415 Fix com_err library to make it more compatible with recent changes
1416 made to the com_err library in MIT Kerberos V5 version 1.4.
1417 (Addresses Sourcefroge Bug #1150146)
1419 General cleanup of messages printed by e2fsprogs programs for grammar,
1420 consistency, and to make life easier for translators. Fixed a few
1421 strings containing English that had not been marked as needing
1422 translations. Removed strings that do not need to be translated, to
1423 make life easier for translators.
1425 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
1426 test to see if a device appears to be in use instead of just relying
1427 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
1429 Fix portability problem in the filefrag program affecting platforms
1430 where the size of an integer is smaller than the size of a long.
1431 (Addresses Debian Bug #309655)
1433 Mke2fs will now use a larger journal by default for filesystems
1434 greater than 4GB. (128 MB instead of 32MB).
1436 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
1437 unless forced. This is to avoid signed vs. unsigned kernel bugs in
1438 block numbers that still need to be fixed.
1440 The blkid program has a new option which will more efficiently search
1441 for device when it is known (or expected) that only one matching
1442 device will be found in the system, such as when doing a lookup by
1445 Debian's e2fsprogs-specific initrd fragment will avoid including
1446 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
1447 and LD_LIBRARY_PATH, and filtering out libraries found in
1448 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
1450 Fixed a potential portability issue in the blkid programs for
1451 architectures where the char type is unsigned. (Addresses Sourceforge
1454 Fix a bug in filefrag so that it doesn't falsely count an extra
1455 discontinuity when the first block found is an indirect block.
1456 (Addresses Debian Bug #307607).
1458 Fix blkid's recognition of cramfs filesystems, and enhance it to be
1459 able to handle cramfs labels.
1461 Fix debugfs's stat command to not core dump when a filesystem is not
1464 Fix e2fsck's handling of error conditions caused by the resize inode
1465 claiming blocks that are also used by other inodes, a filesystem
1466 corruption which was commonly caused by a bug in Fedora Core 3's
1469 Fixed bug in filefrag which caused it to fail on non-ext2/3
1470 filesystems. (Addresses Debian Bug: #303509)
1472 If the superblock last mount time indicates that the system clock may
1473 not be accurate, then e2fsck will omit checking inodes' deletion time
1474 field for indications of a potential corrupted orphaned inode list.
1475 (Previously e2fsck only ommited these LOW_DTIME checks when the
1476 superblock's last write time looked insane.)
1478 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
1479 (Addresses Debian bug #302200)
1481 Make the blkid library more paranoid about being run from setgid
1482 programs, and to use __secure_getenv() from libc if it is available.
1484 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1485 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
1486 and Sourceforge Bug: #1189803)
1488 Updated and fixed translations.
1490 Fixed various Debian packaging issues --- see debian/changelog for
1496 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
1497 changed to take an unsigned int for the bit number. Negative bit
1498 numbers were never allowed (and didn't make any sense), so this should
1499 be a safe change. This is needed to allow safe use of block numbers
1500 greater than or equal to 2**31.
1502 The compile_et program will avoid recreating generated foo_err.c and
1503 foo_err.h files if no changes are necessary. The compile_et program
1504 will also atomically replace these files to avoid a potential parallel
1505 build race problem on SMP systems. (Addresses Sourceforge Bug:
1508 Added a new function to the blkid library, blkid_probe_all_new(),
1509 which only probes newly added disk devices, and change
1510 blkid_find_dev_with_tag() to use this function so that when a
1511 requested tag is not found, devices that were previously not checked
1512 are searched before searching all devices in the system.
1514 Added new functions to the blkid library, blkid_dev_set_search() and
1515 blkid_dev_has_tag().
1517 E2fsck's problem strings can now use @m and @n as abbrevations for
1518 "multiply-claimed" and "invalid", respectively.
1520 The e2fsprog.pot file now has an explanation of how the @-expansion
1521 and %-expansion works, and strings in e2fsck/problem.c which contain @
1522 characters now have comments in e2fsprogs.pot with the @-expansion to
1523 make life easier for translators.
1525 Fixed missing return values in the ext2fs library which could cause it
1526 to return random garbage in certain error conditions.
1528 Allow the current time to be overriden via the E2FSCK_TIME environment
1529 variable for use in regression tests.
1531 The test scrpit driver program now exits with a non-zero status if
1532 there any of its test that it ran failed.
1534 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
1537 Fixed "make check" so that it compiles correctly even when e2fsprogs'
1538 header files have not be installed in the system include directories.
1539 (Addresses Sourceforge Bug: #1180572)
1541 Fixed gcc -Wall nits.
1544 E2fsprogs 1.37 (March 21, 2005)
1545 ===============================
1547 Add support for checking the validity of Extended Attributes stored in
1550 Add support for dumping the contents of large inodes to debugfs,
1551 including the extended attributes stored in inodes.
1553 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1554 when we create a new inode we make sure that the extra information in
1555 the inode (any extra fields in a large inode and any ea-in-inode
1556 information) is initialized correctly. This can take place when
1557 mke2fs creates the root and lost+found directory, when e2fsck creates
1558 a new root inode or a new lost+found directory, and when the user uses
1559 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1560 create inode could inherit garbage (or old EA information) from a
1561 previously deleted inode.
1563 Fixed a bug in e2fsck so it would notice if a file with an extended
1564 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1567 Added support to filefrag to detect files which are using the new
1568 experimental file extents format, and use the non-ext2 algorithm in
1569 that case. Fixed a bug to avoid reporting a false discontinuity if
1570 there is one or more unallocated blocks at the beginning of a file.
1572 Duplicated a check for noticing whether or not the number of blocks
1573 (given a certain blocksize) is greater than 2**32 when the
1574 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1575 allows mke2fs to automatically use a larger blocksize when creating a
1576 filesystem on a very large device when run on systems that do not
1577 support BLKGETSIZE64.
1579 Fix the I18N build which was broken in e2fsprogs 1.36 because the
1580 build system had been switched to treat the .gmo files as shipped
1581 files (for backwards compatibility with systems that have older GNU
1582 I18N tools installed), but the gen_tarball.in script was still
1583 removing the .gmo files from the official source distribution.
1585 Fixed various Debian packaging issues --- see debian/changelog for
1586 details. (Addresses Debian Bugs ##296769, #299341)
1591 Added new functions to the e2p library which convert between a string
1592 and os_type: e2p_os2string() and e2p_string2os(), and used them to
1593 make the generated binaries more compact.
1595 Fixed a compile-time error on Darwin systems.
1597 Cleaned up the lib/ext2fs Makefile slightly.
1600 E2fsprogs 1.36 (February 4, 2005)
1601 =================================
1603 All of the patches that were applied to Fedore Core 3's
1604 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1605 lot of bug fixes first. Users of Fedora Core 3 are strongly
1606 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1608 Add support for filesystem with the online resizing via resize inode
1609 feature. Fixed numerous bugs from the Fedora patches. The Fedora
1610 patches also didn't bother to do any consistency checking on the
1611 resize inode, or add any tests to the regression test suite. The "-R
1612 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1613 being listed in mke2fs's usage message. All of these shortcomings
1614 have been corrected.
1616 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1617 program. In order to do this, the user must run the commands:
1619 debugfs -w /dev/hdXXX -R "features ^resize_inode"
1620 e2fsck -f /dev/hdXXX
1622 Optionally, the ext2prepare command can be used to re-enable online
1623 resizing after the filesystem has been fixed.
1625 The fsck program will now accept an optional filedescriptor argument
1626 to the -C option. (The Fedora version of this patch would sometimes
1627 cause fsck to ignore a parameter on fsck's command line in some rare
1630 Make sure e2fsprogs doesn't write garbage into the reserved portion of
1633 Make sure resize2fs releases the blocks belonging to the old inode
1634 table blocks when moving the inode table. (Addresses Debian Bug:
1637 Skip the r_resize_inode test if resize2fs is not compiled (due to
1638 configure --disable-resizer)
1640 E2fsck now checks the summary filesystem accounting information, and
1641 if any of the information is obviously wrong, it will force a full
1642 filesystem check. (Addresses Debian Bug #291571)
1644 Fix e2fsck to not complain when the resize_inode feature is enabled,
1645 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1648 Fix e2fsck to note delete symlinks that contain an extended attribute
1649 after the ext_attr feature flag has been cleared. (Addresses Red Hat
1652 Add new utility program, copy_sparse.c, which is very useful
1653 for dealing with large sparse files (such as e2image files).
1655 Add support for jnl_blocks[] for debugfs's set_super_value.
1657 Fix filefrag so that it works correctly with sparse files.
1659 Filefrag -v will print first and last blocks.
1661 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1664 Add mke2fs support so that it can support filesystems larger than 4TB
1665 automatically, by retrying with a 4k blocksize if the device size is
1666 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1669 Change blkid to test for NTFS first because Windows sometimes doesn't
1670 clear enough of the parition to confuse the probing routines into
1671 thinking the old filesystem type is still valid. (Addresses Debian
1674 Add support for swap partition label and uuid's in the blkid library.
1676 Add support to the blkid library to recognize Oracle ASM volumes.
1678 Make blkid -t display all devices that match the specified criteria,
1679 not just the first one, and work more consistently when the blkid
1680 cache file is not available or set to /dev/null. (Addresses Debian
1681 Bug #290530 and #292425)
1683 Badblocks will now correctly display block numbers greater than
1684 999,999,999 in its progress display.
1686 The tune2fs program will not allow the user from setting a ridiculous
1687 number of reserved blocks which would cause e2fsck to assume the
1688 superblock was corrupt. E2fsck's standards for what is a ridiculous
1689 number of reserved block has also been relaxed to 50% of the blocks in
1692 The blkid library will return vfat in preference to msdos, and ext3 in
1693 preference to ext2 (if the journalling flag is set) so that mount will
1694 do the right thing. (Addresses Debian bug #287455)
1696 Mke2fs will now use the -E option for extended options; the old -R
1697 (raid options) option is still accepted for backwards compatibility.
1698 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1700 Mke2fs will now accept a size in megabytes, gigabytes, and other units
1701 (via "32m" or "4g" on the command line) if the user finds this more
1702 convenient than specifying a block count.
1704 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1705 cache conherency problem.
1707 Debugfs now supports a new command, set_inode_field, which allows a
1708 user to manually set a specific inode field more conveniently, as well
1709 as set entries in the indirect block map.
1711 Debugfs's set_super_value command has been enhanced so that the user
1712 can set most superblock fields, including the date/time fields and
1713 some of the more newsly added superblock fields.
1715 E2fsprogs programs now accept an offset to be passed to the file
1716 specifiers, via the syntax: "/tmp/test.img?offset=1024".
1718 E2fsprogs programs will now accept blocksizes up to 65536; kernel
1719 support on the x86 doesn't exist for now, but it can be useful on
1720 other architectures with page sizes greater than 4k. There are 2.6
1721 kernel patches out there which enable this, but they are of this
1722 writing still experimental.
1724 The e2image command now takes the -s option which will scramble
1725 directory entries for raw image files.
1727 Fix a file descriptor leak in the filefrag program.
1729 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1732 Fix bug in debugfs where kill_file would lead to errors when deleting
1733 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1735 Fix bug in the blkid library when detecting the ocfs1 filesystem
1737 Remove obsolete EVMS 1.x and a.out DLL support.
1739 E2fsck will attempt to recover from a journal containing illegal blocks.
1741 Fixed two potential ordering constraint problems in e2fsck which might
1742 cause the filesystem to be corrupted if e2fsck is interrupted during a
1743 (extremely narrow) race window. Thanks to Junfeng Yang from the
1744 Stanford Metacompilation group for pointing this out.
1746 Fixed bug in e2fsck where it would not accurately detect whether or
1747 not the system is running on adaptor if the ACPI device representing
1748 the AC adapter didn't correspond to the what was used on IBM
1751 Change e2fsck to accept directories greater than 32MB.
1753 Fix e2fsck so that a checkinterval of zero disables a time-based check
1756 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
1757 to the PAGER environment variable. (Addresses Debian Bug #239547)
1759 Tune2fs will not mark rewrite the superblock if the feature bitmasks
1762 The debugfs program will set the filetype information when creating a
1765 Add debugfs -d option to use a separate source of data blocks when
1766 reading from an e2image file.
1768 Add e2image -I option which allows the e2image metadata to be
1769 installed into a filesystem.
1771 Fixed bug in the badblocks program which caused "done" to always
1772 appear in english even when a translation was available. (Addresses
1775 The blkid program has a new option -o which controls the output format
1776 of the blkid program; this is makes blkid more convenient to use in
1779 Fix a minor bug in uuid library, which was not using the full 14 bits
1780 of clock sequence when generating UUID's.
1782 Fix a Y8.8888K problem in the uuid library.
1784 Logsave now creates a new session id for itself to avoid getting
1785 killed by init whan transitioning between init levels.
1787 Change the licensing of the UUID library to be the 3-clause BSD-style
1788 license; this allows Apple to use the uuid library in Darwin.
1790 Add ocfs and ocfs2 probe support into the blkid library.
1792 Fix a memory and file descriptor leak in the blkid library.
1794 The blkid library will revalidate the device if the system time is
1795 earlier than last verification time of the device, since that
1796 indicates that the system time is probably nottrustworthy.
1798 The blkid library will override the default location of the blkid.tab
1799 file by the BLKID_FILE environment variable, if it is available.
1801 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
1803 Add various portability fixes for lame new versions of glibc, Darwin
1804 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
1805 Bugs #239934, #264630, #269044, #255589, #289133)
1807 Add support for Windows 9x/NT under Cygwin.
1809 Updated and clarified various man pages. (Addresses Debian Bugs #236383,

1812 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
1814 Update the rpm spec files so that it works better with Fedora core 2
1817 Fixed various Debian packaging issues (see debian/changelog). In
1818 particular, fixed the Debian initrd scripts. (#241183, #248050,
1825 Fixed various gcc -Wall warnings.
1827 The uuid library now has new functions uuid_unparse_upper() and
1828 uuid_unparse_lower() which forces the case of the hex digits to be
1829 upper case, or lower case.
1831 The build process has been speeded up by enhancing the subst program
1832 to update the modtime on the generated files even when the generated
1833 file hasn't changed.
1835 The uuid library now uses C99 stdint.h types instead of custom types.
1837 Updated config.guess and config.sub with newer versions from the FSF.
1839 Removed out of date .cvsignore files from the source distribution.
1841 The ext2fs_unlink() function will return an error if both the name and
1842 inode number are unspecified, to avoid doing something surprising
1843 (such as unconditionally deleting the first directory entry).
1844 Directory entries are now deleted by coalescing them with the previous
1845 directory entry if possible, to avoid directory fragmentation. This
1846 is not an issue with the e2fsprogs suite, but may be a problem for
1847 some of the users of libext2fs, such as e2tools.
1849 Add support for version numbers of the form "1.36-rc1".
1851 Fix build of mke2fs.static.
1853 Add basic ext2fs library support for large (EA in inode) inodes.
1855 The test_io mechanism can now abort after n reads or writes to a
1856 particular block. The block is specified by TEST_IO_BLOCK environment
1857 variable, and the read/write count by the TEST_IO_READ_ABORT and
1858 TEST_IO_WRITE_ABORT environment variables. The block data is now only
1859 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
1861 UUID_DEFINE() in the uuid library now creates a static variable, with
1862 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
1863 be used in header files.
1865 Add support for the install-strip and install-shlibs-strip targets, as
1866 suggested by the GNU coding guielines. "make install" no longer
1867 strips the binaries which are installed.
1869 Remove support for the --enable-old-bitops configure option which was
1870 only for very old sparc systems.
1872 Remove support for --enable-clear-htree; this was only needed during
1873 the early development of the htree patch.
1875 Use Linux-kernel-style makefile output so it is easier to see compiler
1878 Update gettext files to version 0.14.1.
1880 Update to use autoconf 2.5x.
1882 Improved support for compiling e2fsprogs under dietlibc.
1884 Make e2fsprogs portable to Solaris and FreeBSD systems.
1886 Add blkid_verify(), blkid_get_library_version(), and
1887 blkid_parse_version_string() functions to the blkid library.
1889 Add pkg-config files for e2fsprogs's libraries.
1891 Fix "make uninstall" to so that it removes everything that is installed.
1893 Add a configure --enable-maintainer-mode option which enables the
1894 makefile rules to rebuild the configure script from configure.in, and
1895 to reubuild the .gmo files in po directory.
1897 Drop the sparc assembly bitwise operations; it's less efficient
1898 than the GCC 3.4 compile code and triggers compiler warnings on
1899 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
1900 (Addresses Debian Bug #232326)
1903 E2fsprogs 1.35 (February 28, 2004)
1904 ==================================
1906 E2fsck has a new -k option, which in conjunction with the -c options,
1907 preserves the existing badblocks list.
1909 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
1911 E2fsprogs will now deal correctly with symlinks that contain
1912 extended attribute information, which can be created using SE Linux.
1913 (Addresses Debian Bug #232328)
1915 Remove a double longjump into an invalid stack frame bug in e2fsck.
1916 (This was during an abort sequence, which normally worked on Linux and
1917 caused a core dump on other operating systems.)
1919 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
1920 (the NLS library will replace "" with the .po header information).
1922 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
1923 dump due to a division by zero error. (Addresses Debian bug #207082)
1925 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
1926 when reconnecting a directory requires creating a lost+found
1927 directory. (Addresses Debian bug #219640).
1929 Fixed a bug where e2fsck would bomb out if a journal needed to be
1930 replayed when using an alternate superblock.
1932 E2fsck will give an extra grace period before actually forcing a check
1933 if the laptop is running on battery. The next time fsck runs while
1934 the system is on the AC mains, or after the grace period is exceeded,
1935 the filesystem will be checked. (Addresses Debian bug #205177)
1937 E2fsck will inform the user when there are 5 or fewer mounts before a
1938 filesystem check will be forced. (Addresses Debian bug #157194)
1940 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
1941 We now correctly handle the case where there is an overlap between a
1942 block group descriptor or a superblock and a bad block indirect block.
1943 In the case where the indirect block is corrupted, we now suggest
1946 Fix byte swap bugs in e2fsck that caused the journal backup location
1947 in the superblock and symlinks created by SE Linux to be cleared
1948 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
1950 E2fsck -c now replaces the current list of bad blocks with the ones
1953 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
1954 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
1956 Fix a potential bug in e2fsck which could cause it to core dump when
1957 trying to print the location of the backup superblock.
1959 Protect against a potential core dump in e2fsck when printing a
1960 message about backup superblocks.
1962 Add support for backing up the journal inode location in the
1963 superblock. E2fsck will automatically save the journal information in
1964 the superblock if it is not there already, and will use it if the
1965 journal inode appears to be corrupted. ext2fs_add_journal_inode()
1966 will also save the backup information, so that new filesystems created
1967 by mke2fs and filesystems that have journals added via tune2fs will
1968 also have journal location written to the superblock as well.
1969 Debugfs's logdump command has been enhanced so that it can use the
1970 journal information in the superblock.
1972 E2fsck will now update all superblocks when moving the journal inode.
1974 Shrink the size of the e2fsck executable by moving some initialized
1975 variables to the BSS segment.
1977 E2fsck will avoid printing the ^A and ^B characters which bracket the
1978 progress bar when stdout and stdin are a tty device instead of a pipe
1979 to another program. (Addresses Debian bug #204137)
1981 Debugfs's mkdir command will automatically expand the directory if
1982 necessary. (Addresses Debian Bug: #217892)
1984 Fixed a bug in debugfs so that copying a file from /dev/null uses the
1985 correct mode bits. (Addresses Debian Bug: #217456)
1987 If the environment variables DEBUFS_PAGER and PAGER are not set,
1988 debugfs now searches for the appropriate pager to use, beginning with
1989 /usr/bin/pager, and then falling back to 'more' and 'less'.
1990 (Addresses Debian bug #221977)
1992 Debugfs will now support 2.6 device numbers where the major or minor
1993 number may be larger than 255. (Addresses Sourceforge bug #865289)
1995 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
1997 Chattr now stops processing options when it sees '--'. (Addresses
2000 Fix regression tests so they work correctly when e2fsprogs is compiled
2001 with configure --disable-htree.
2003 Fix bug in uuid library when there is no network card and the library
2004 is generating a time-based uuid. The random MAC address was not
2005 correctly generated to be a multicast address.
2007 Add compile_et extensions from Heimdall that were missed the first time
2010 Fix bug in badblocks when using O_DIRECT; we need to make sure that
2011 we're reading from an offset which is page aligned. For read-only and
2012 read-write tests, we try to recover after an error so that we can
2013 continue reading on page-aligned boundaries. (Addresses Debian Bug
2016 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
2019 Updated and clarified various man pages. (Addresses Debian Bug
2020 #206845, #222606, #214920, #232406)
2022 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
2024 Fixed various Debian packaging issues (see debian/changelog).
2029 Fixed a build problem so that e2fsprogs would compile with the
2030 --enable-profile option to configure selected. (Addresses Sourceforge
2033 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
2034 Bugzilla Bug #112448)
2036 Centralize code which calculates the location of the superblock
2037 and block group descriptors so that it is in a single library routine.
2039 Added two new functions, ext2fs_file_open2() and
2040 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
2042 Fix compile_et to output the correct prototype for
2043 initialize_xxx_err_table_r() in the header file. (Addresses Debian
2046 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
2048 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
2049 present. This is for when we try stuffing an int into void * pointer.
2051 Fix type-punning which can cause gcc 3.x to miscompile code by getting
2052 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
2053 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
2054 **'. The EVMS code uses an ugly union approach since we don't want to
2055 modify the EVMS interfaces.
2057 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
2058 aid build process on systems can use invoke GNU make as "gmake".
2060 Added regression testing for mke2fs.
2062 Fixed gcc -Wall nitpicks.
2064 Fixed various compiler warnings.
2066 Add portability fixes for FreeBSD and for using fsctl under Darwin to
2067 support ext2 ioctl's.
2070 E2fsprogs 1.34 (July 25, 2003)
2071 ===============================
2073 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
2074 a tight loop while waiting for a child fsck to exit in some cases.
2075 This burns CPU times which slows down the low-level filesystem check.
2077 Added code to mke2fs to assure that the default block size for a
2078 filesystem is at least as big as the sector size of the device, if it
2081 Changed mke2fs and resize2fs to round the default size of a filesystem
2082 to be an even multiple of the VM pagesize in order to avoid a Linux
2083 kernel bug introduced when the storage of the buffer cache was moved
2084 into the page cache.
2086 Mke2fs will warn the user when creating a filesystem with journaling
2087 and a blocksize greater than 4096. (Addresses Debian bug #193773)
2089 Fixed a bug in resize2fs which caused it to fail on filesystems with a
2090 non-empty bad block list. Resize2fs now discards any blocks on the
2091 badblock list which are no longer part of the filesystem as the result
2092 of a filesystem shrink. (Note: this means that shrinking and then
2093 enlarging a filesystem is no longer a reversible operation;
2094 information about bad blocks in the part of the filesystem which is to
2095 be chopped off will be lost.)
2097 Changed resize2fs so the user can use prefixes to specify the units of
2098 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
2099 and to make the error and informational messages explicitly display
2100 the blocksize used by the filesystem, in order to avoid confusion.
2101 (Addresses Debian bug: #189814)
2103 Added a new debugfs command, dump_unused, which dumps the contents of
2104 all unused blocks to stdout. (Useful as an emergency try-to-find
2105 deleted data command.)
2107 Added a new debugfs command, imap, which prints the location of a
2108 specified inode in the inode table.
2110 Fixed a bug in the badblocks program which caused it to use one bit of
2111 randomness in its non-destructive read/write test, instead of using a
2112 full 8 bits of randomness.
2114 Added a new option (-t) to badblocks, which allows the user to control
2115 the test pattern(s) used when checking a disk.
2117 The blkid probe function now more correctly detects UDF filesystems.
2119 Fixed a bug in the blkid library which caused it to not update its
2120 cache if a filesystem changes from having a label to not having a
2123 Fixed a bug in the blkid library wihch could avoid an infinite loop
2124 in blkid_find_dev_with_tag() if /proc is not mounted and there the
2125 /etc/blkid.tab file has not yet been created.
2127 Fixed the badblocks program so that the destructive read/write test
2128 honors the -c option, and to use O_DIRECT when possible to avoid
2129 thrashing the system block buffer cache.
2131 Fixed various NLS issues.
2132 - Added Czech and Swedish translations
2133 - Removed testing NYC translation
2134 - Fixed NLS support for message abbrevations in e2fsck
2135 - Remove de-utf.po, since we shouldn't have two versions using different
2137 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
2138 simplify the statistics reporting in e2fsck.
2140 Changed configure.in so that its defaults for *BSD systems no longer
2141 build an fsck wrapper, and not to install in /usr/local by default.
2143 Fixed some minor spelling errors/typo's in e2fsck and the configure
2146 Fixed various Debian packaging issues (see debian/changelog).
2148 Updated and clarified man pages. (Addresses Debian Bug #195616)
2153 Fix gcc -Wall nitpicks.
2155 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
2156 NLS support by default. (Added partial workaround for gettext/Darwin
2157 incompatibility problems.)
2159 Added full MIT KRB5 and Himdall compaibility support to the com_err
2160 library and the compile_et program. (Addresses Debian bug #191900)
2162 Added the blkid_known_fstype() function to the blkid library, which
2163 returns true if it is passed a filesystem type which is recognized by
2164 the blkid probing functions.
2166 Improved the documentation for the blkid library.
2168 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
2169 returns the hardware sector size of a device, if it is available.
2171 Added a dependency in the blkid library's .so file to the uuid
2172 library, since the former uses the latter. (Addresses Debian bug
2175 Added --with-diet-libc and --disable-evms to the configure script.
2177 Fixed a minor memory leak in the badblocks program.
2179 Fixed a portability problem in tune2fs --- not all systems have strptime().
2181 Fixed a portability problem in debugfs with the use of getopt() more
2182 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
2185 Add support Windows support to ext2fs_get_device_size().
2187 Added (normally disabled) debugging code to the Unix I/O manager which
2188 causes it to disable all userspace caching if the NO_IO_CACHE is
2191 Changed the test I/O manager so it can always be linked into e2fsck,
2192 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
2193 configure script. The test I/O manager will only print any debugging
2194 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
2195 variables are set, which specifies which I/O operations are logged and
2196 a block number to watch, respectively. The log messages are sent to
2197 stderr by default, unless a filename is specified via the
2198 TEST_IO_LOGFILE environment variable.
2201 E2fsprogs 1.33 (April 21, 2003)
2202 ===============================
2204 Added a new utility program, logsave, which captures the output of a
2205 command in a log file, even if the containing directory hasn't been
2206 mounted yet (in which case the it saves the output in memory until it
2207 can write out the logfile). This is useful for capturing the
2208 output of fsck during the boot sequence.
2210 Fixed some portability problems that were causing problems under
2211 the Cygwin32 environment.
2213 Mke2fs now interprets a negative number to the -b option as a minimum
2216 Fixed a bug in mke2fs which was incorrectly checking the argument to
2217 the -g option if the default block size was used. (Addresses Debian
2220 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
2221 it can not find filesystem checkers for jfs, reseirfs, and xfs.
2223 E2fsck now updates the global free block and inode counters from the
2224 block group specific counters quietly. This is needed for an
2225 experimental patch which eliminates locking the entire filesystem when
2226 allocating blocks or inodes; if the filesystem is not unmounted
2227 cleanly, the global counts may not be accurate.
2229 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
2230 2.0 is not yet supported; this only pulled in the bug fixes: fixed
2231 possible hangs caused by bugs in calling waitpid, and not setting the
2232 pipe to non-blocking mode; also fixed a file descriptor leak; made
2233 sure all functions call log entry/exit functions.)
2235 Badblocks now flushes its output file as bad blocks are discovered.
2237 The uuid library is now more paranoid about assuming the correctness
2238 of the /dev/random device; it mixes in a stream of bytes from
2239 random/srandom, just in case.
2241 Update Debian files to reflect the fact that I am now the Debian
2242 maintainer of e2fsprogs. Other various Debian-specific packaging
2245 Move the source tarball generation functions from the top-level
2246 makefile to the util/gen-tarball script.
2248 Updated the Turkish .po translation file.
2250 Added Heimdal and MIT krb5 extensions to the com_err library to make
2251 it more compatible with com_err libraries from those distributions.
2253 Changed dumpe2fs to always display the superblock fields relating to
2254 the journalling and/or directory indexing feature even if those
2255 features are not enabled.
2257 Updated and clarify copyright statement vis-a-vis alpha releases of
2260 The ss library will now try to dynamically link to the readline
2261 library and use it if it is present in the system. This means that
2262 the debugfs program now has line editing and history features. The
2263 SS_READLINE_PATH environment variable is used to find a readline or
2264 readline-compatible library.
2266 E2fsck now finds most duplicate filenames (all when rebuilding all
2267 directories via the -D option) and offers to delete or rename
2268 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
2270 Fix bug in e2image. When writing out a raw image file, include data
2271 blocks from symlinks that do not store the symlink within the inode.
2273 Fix bug in resize2fs which incorrectly moved the block and inode
2274 bitmaps for sparse superblock filesystems and incorrectly marked
2275 blocks as in use. (Addresses Debian bug #174766)
2277 Added a new shared library, the blkid library, which efficiently
2278 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
2279 and UUID filesystem specifiers without needing to search all of the
2280 devices in the system. Instead, the device is looked up in a cache
2281 file, and then verified to make sure the blkid cache is correct.
2283 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
2284 the device name, using the blkid library. (Addresses Debian bugs
2287 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
2288 used for spaces in device labels.
2290 Removed 32-bit limitations for debugfs's dump command.
2292 If the user specifies a large number of inodes, Mke2fs will
2293 automatically adjust the number of blocks per group to find a valid
2294 set of filesystem parameters.
2296 Add workaround to detect broken MD devices where when some of the
2297 underlying devices are marked read-only, writes to the MD device are
2298 silently dropped. E2fsck will detect if there is an attempt to run
2299 the journal twice, and abort with an error if this is the case.
2300 (Addresses IBM Bugzilla bug #1226)
2302 E2fsck will print an error if more than one of the -p/-a, -n or -y
2303 options are specified.
2305 E2fsck will fix HTREE corruptions in preen mode, without stopping the
2306 boot process. This is needed because the 2.4 ext2 filesystem
2307 accidentally had the INDEX_FL backwards compatibility code removed.
2309 Mke2fs no longer creates filesystems with the dir_index flag set by
2310 default; the user has to specifically request it.
2312 Update and clarified various man pages. (Addresses Debian bugs
2313 #173612, #175233, #175113, and #170497, #185945, #188318)
2315 Created man page for the mk_cmds program (from the libss library).
2320 Fix various gcc -Wall nits.
2322 Fixed a lot of portability problems that caused e2fsprogs not to build
2323 successfully under Solaris and Apple/Darwin.
2325 Fixed a Makefile dependency to allow building e2fsprogs using parallel
2328 Changes to create a subset distribution which consists only of the
2329 et, ss, uuid, and blkid libraries. The configure script and top-level
2330 makefile were changed to support working with a subset distribution.
2332 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
2333 actually used, and might people who are looking for
2334 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
2336 Updated debian files to fix a number of Lintian warnings.
2338 Updated config.guess and config.sub with newer versions from the FSF.
2340 Removed unnecessary libraries from being linked into the fsck, lsattr,
2341 chattr, and blkid executables.
2343 E2fsprogs 1.32 (Nomvember 9, 2002)
2344 ==================================
2346 Fixed a bug in the Unix I/O routines which caused needless writebacks
2347 of clean blocks from the unix_io cache (they were erroneously marked
2348 as being dirty, so they were getting written back to disk before
2349 getting evicted from the disk cache). This was harmless, but it
2350 significantly slowed down e2fsck.
2352 Made some other minor optimizations to the Unix I/O routines to save a
2353 small amount of CPU time.
2355 Updated internationalization files.
2358 E2fsprogs 1.31 (Nomvember 8, 2002)
2359 ==================================
2361 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
2362 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
2363 handling for child process that die unexpectly. Add a hack to force
2364 mkfs to create filesystems that won't cause problems with hardware
2365 that has 2k or 4k minimum blocksize requirements. Read from child
2366 processes in non-blocking mode, so that the GUI continues to update.
2368 Fix e2fsck so that it returns the appropriate exit code when the root
2369 filesystem has been changed, so that system's rc scripts will be told that
2370 the system needs to be rebooted.
2372 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
2373 was set, some of the descriptor blocks that should have been written
2374 out were getting skipped.
2376 Changed e2fsck to force out changes to the backup copies of the
2377 superblock and block group descriptors when important changes are made
2378 to those data structures.
2380 Fix a bug where e2fsck could erroneously mark a filesystem as being
2381 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
2382 introduced in e2fsprogs 1.28.)
2384 If journal debuging is enabled using --enable-jbd-debug, the debugging
2385 level is now set via the E2FSCK_JBD_DEBUG environment variable.
2387 If byteswapping support is disabled using configure --disable-swapfs,
2388 skip the tests which depend on byte-swapping, so that "make check"
2391 Lshattr will now display the indexed directory flag. Also, some of
2392 the more esoteric compression flags are supressed unless compression
2393 support has been enabled.
2398 E2fsprogs 1.30 (October 31, 2002)
2399 =================================
2401 When resizing a filesystem, and inodes need to moved, resize2fs will
2402 update the inode's ctime field, and the mtime field of the containing
2403 directories, so that incremental backups using dump/restore will work
2406 In order to avoid spurious errors, e2fsck wil check the last
2407 superblock write time to determine whether or not it can safely use
2408 the LOW_DTIME checks to determine if there are inodes on the orphan
2409 inode linked list that had somehow gotten disconnected. (Addresses
2410 Sourceforge bug #620980)
2412 Partition in /proc/partitions that being with the string "lvm" are
2413 considered real partitions even if they do not end with a number.
2415 Fixed a bug in the the uuid generation function, where if /dev/urandom
2416 is not present, but /dev/random is, and there isn't sufficient
2417 entropy, the get_random_byte function could spin a loop forever.
2419 E2fsck, mke2fs, etc. will now reliably notice when image files are
2420 mounted using the loopback interface. (Addresses Sourceforge bug
2423 When flushing buffers (as is done by badblocks, for example) check to
2424 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
2425 FDFLUSH ioctl which causes the MD device driver which causes confusing
2426 syslog messages about obselete ioctl messages. (Addresses Sourceforge
2429 Debugfs's write command now checks to see if the destination filename
2430 exists before creating it. (Addresses Sourceforge bug #478195.)
2432 When installing man pages, search for compressed man pages using all
2433 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
2435 Fixed a bug in fsck where multiple filesystems specified on the
2436 command were not being checked in parallel due to a logic bug
2437 introduced to support the FSCK_MAX_INST environment variable.
2439 We have added a new superblock field, s_mkfs_time, which indicates
2440 when a filesystem was created. It is set via mke2fs, and printed out
2441 by dumpe2fs, but is not actually touched by the kernel.
2443 Dumpe2fs has been made more robust by not aborting if there is an
2444 error reading the block/inode bitmaps; instead it will still print out
2445 the location of the block/inode bitmaps and inode table.
2447 Add support for the an alternative block group descriptor layout which
2448 allows for on-line resizing without needing to prepare the filesystem
2449 in advance. (This is the incomat feature flag meta_bg.)
2451 Add support for storing default mount options in the superblock, so
2452 that the filesystem can be mounted with specific mount options without
2453 needing to specify them on the mount command line or in the /etc/fstab
2456 Add support for a new inode flag, which is to be used for indicating
2457 the top of directory hierarchies for the Orlov block allocator.
2459 Fix e2fsck so that if it creates the lost+found directory, it does so
2460 with the more apporpriate permissions of 0700. Also change
2461 mklost+found so that it also creates the directory 0700.
2463 Fixed format bug in e2fsck if NLS is in use.
2465 Add a German translation for e2fsprogs's NLS support.
2467 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
2468 the beginning of the inode table. This won't matter much, since if
2469 there is a bad block at the beginning of the inode table, the root
2470 directory won't be available. But at least e2fsck won't crash in this
2473 Fixed endian problems in the htree code for e2fsck and debugfs.
2475 When byte-swapping a filesystem on a PPC architecture, byte-swap the
2476 bitmaps since the historical big-endian ext2 variant had byte-swapped
2477 bitmaps, and the ext2fs library assumes this. This fixes the
2478 regression test suite on PPC machines.
2480 Fix e2image so that it handles a bad block in the inode table
2483 E2fsck now uses a more sophisticated algorithm to salvage corrupted
2484 directories that recovers more information in the corrupted directory
2487 E2fsck now performs additional consistency checks on indexed (HTREE)
2490 Fix bug where efsck might get confused about whether a completely
2491 empty directory block is an empty leaf block or an interior htree
2492 node. This could cause e2fsck to get confused into think that a valid
2493 indexed directory was corrupted.
2495 E2fsck no longer creates an empty directory entry at the end of a
2496 directory block when optimizing a directory. This would cause some
2497 earlier versions of the dxdir kernel code to corrupt the directory
2498 when attempting to split a node containing an empty directory entry.
2500 E2fsck could sometimes in rare circumstances leave the indexed flag
2501 set after a small directory was optimized by compressing it instead of
2502 indexing it. (This should never happen in real life, since
2503 directories that small wouldn't have been indexed, but better safe
2506 E2fsck now only updates the master superblock in all cases. This
2507 slightly shortens its run time.
2509 Ext2ed can deal with directory entries of length 0; previously it
2510 would get stuck in an infinite loop.
2512 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
2513 specifiers. (Sourceforge patch #613447)
2515 Badblocks will now work correctly on read-only devices such as
2516 CD-ROM's. (Sourceforge patch #600451)
2518 Updated and clarified man pages. (Addresses Debian bug #167108)
2521 E2fsprogs 1.29 (September 24, 2002)
2522 ===================================
2524 Fixed a bug in e2fsck which could corrupt a directory when optimizing
2525 it (via the -D option) or rebuiliding the hash tree index with a 1 in
2526 512 probability, due to a fence post error.
2528 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
2531 Mke2fs now enables the directory indexing flag by default. (Since
2532 this is a compatible feature flag, it's safe to do so.)
2534 Tune2fs will support setting the directory indexing feature flag. It
2535 will automatically set up the default hash algorithm and hash seed
2536 fields in the superblock.
2538 If the bone-headed user enters the root filesystem twice in
2539 /etc/fstab, the -R option which skips the root filesystem will skip
2540 all of them. (Addresses Debian bug #159423). Note! This is not a
2541 precedent for dealing intelligently with any other kind of doubled
2542 entry in /etc/fstab!
2548 Removed perror declaration in lib/et/internal.h. All modern systems
2549 can be expected to define perror() these days. Besides, the lib/et
2550 code wasn't using perror at all anyway. :-)
2553 E2fsprogs 1.28 (August 31, 2002)
2554 ================================
2556 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2557 for setting the htree flag is not included yet, although it can be
2558 manually turned on via the debugfs program.
2560 Clarified e2fsck error message which is printed when it cannot find
2561 sufficient contiguous block when relcating filesystem metadata.
2563 Added support for building an EVMS plugin module for ext2/3. This
2564 module is substantially the same as the EVMS module shipping with EVMS
2565 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
2566 for use with EVMS 1.0 (which did not include the ext2 plugin module),
2567 if the configure --enable-old-evms flag is given.
2569 Fsck will search through EVMS volumes when trying to resolve
2570 filesystem specifications such as LABEL=xxx or UUID=xxx.
2572 Added a new utility program, /sbin/findfs, which will return
2573 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2576 Update and clarified various man pages. (addresses Debian Bug #145044,
2577 #146437, #131350, #151990, #144621, #141938)
2579 If there are no filesystems specified on fsck's command line, fsck now
2580 treat that as if the -As options were given. Previously it would
2581 simply do nothing. (Addresses Debian Bug #153102)
2583 Mke2fs no longer treats a failure to be able to clear the MD signature
2584 at the end of the filesystem as a fatal error. (Addresses Debian Bug
2587 The e2p library functions (which are used by lsattr and chattr) now
2588 double check to make sure the file is a regular file or directory
2589 before attempting to use the ext2 ioctls. Some device drivers
2590 unfortunately respond to the ext2 ioctl's with unknown behaviour.
2591 (Addresses Debian Bug #152029).
2593 The extended attribute handling has been updated to correspond with
2594 the latest V2 bestbits ACL code.
2596 Fixed bug in e2fsck which caused it to not clear the dtime field when
2597 processing truncated inodes on the orphan list. This could cause data
2598 loss(!) if a filesystem is rebooted before a truncate has been
2601 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2602 algorithms. This makes e2fsck much faster in the case of severely
2603 corrupted filesystems where a large number of blocks are claimed by a
2604 large number of inodes. (Thanks to the 2.5 IDE device driver for
2605 inspiring this work.)
2607 Resize2fs has been significantly sped up when shrinking and expanding
2608 a filesystem by a very small number of blocks (for example, when EVMS
2609 is converting a partition to be an EVMS legacy volume).
2611 Added a new option to e2fsck, -D, which will optimize or compress all
2612 of the directories in the filesystem.
2614 E2fsck now catches SIGINT and SIGTERM to make sure it will can
2615 properly clean up and only exit at safe points. Fsck will pass
2616 SIGINT/SIGTERM to its child processes, and wait until they have all
2617 exited before it exits.
2619 The uuid parsing code in the uuid library now properly complains when
2620 an illegally formated uuid is presented to it. (Addresses Debian bug
2623 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2624 and 2.4.17, since the workaround can cause problems when using a 2.4
2625 kernel with an old version of glibc built with the 2.2 headers.
2627 Fixed a bug in mke2fs where it wasn't properly clearing the initial
2628 superblock used by other filesystems. (Addresses Debian bug #147256.)
2630 Added support for the synchronous directory feature written by Andrew
2633 The debugfs program can delete directories using the rmdir command.
2635 Add support for 8k and 16k filesystems (for systems with page sizes
2636 that are greater or equal to 8k or 16k, respectively). Note that
2637 these filesystems can not be mounted on x86 systems, or other systems
2638 with only 4k page sizes, due to limitations in the current Linux VM
2641 Resize2fs requires that the filesystem state be valid and have no
2642 errors; otherwise, e2fsck -f must be run first. (Previously it simply
2643 required that the last fsck time be greater than the last mount time.)
2645 Configure now defaults the man pages directory to /usr/share/man on
2648 E2fsck now offers to truncate inodes which contain too many blocks (so
2649 that i_blocks would overflow. Also fixed handling of large sparse
2652 E2fsck now more completely checks for symlink validity, including
2653 requiring NULL termination and length checks.
2655 E2fsck will offer to try forcing a disk write to remap a bad block
2656 after finding a read error when reading a filesystem metadata block.
2658 Fixed a bug in debugfs which caused the -b and -s options to crash
2659 debugfs, as well as breaking the testb, setb, and clearb functions.
2661 Added a bmap command to debugfs which calculates the logical to
2662 physical block mapping for a particular inode.
2664 Fixed a bug in code which checked to see if a device was mounted which
2665 sometimes (rarely) failed in the case of a plain file.
2667 Fixed a bug in resize2fs where when it reported an error, it would
2668 print a message erroneously indicating that the filesystem had been
2669 resized before it aborted.
2671 When resizing a plain file which is smaller than the requested size,
2672 resize2fs will attempt to extended the file so that programs like
2673 e2fsck will not complain that the file is too small.
2675 Resize2fs will print the actual new size of the filesystem when it is
2678 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2679 information on big-endian systems.
2685 Fixed collisions with C++ reserved words.
2687 Added portability fixes for building e2fsprogs on the HURD and AIX.
2689 Added the ext2ed program for creation of test cases. (ext2ed has many
2690 limitations and bugs which make it unsuitable for production use.)
2692 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2693 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2694 name_len field is byte swampped on big-endian machines, since in the
2695 V2 structure, name_len is a char field which is doesn't need to be
2696 byte swapped --- except if an old-style kernel had byte-swapped the
2697 name_len field as part of the V1 structure.
2700 E2fsprogs 1.27 (March 8, 2002)
2701 ==============================
2703 The warning messages for mke2fs now go to standard error.
2705 Fixed to make sure "make check" runs all of the test programs with
2706 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2708 The mke2fs program checks the boot sector for the BSD disk label, and
2709 avoids erasing it if it is there.
2711 Fixed a bug in e2fsck which caused it to core dump if the journal
2712 inode was missing when it was supposed to be there.
2714 E2fsck now prints ranges in pass 5 when printing deltas for the block
2717 Debugfs's "ls -l" command now will print out the file type information
2718 in the directory entry.
2720 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2721 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2723 Debugfs can now examine the experimental directory indexing
2726 Fixed bug in debugfs which caused it to core dump if modify_inode is
2727 called without an open filesystem.
2729 The debugfs lsdel command now runs its output through a pager first.
2731 When installing manual pages, remove the compressed manual pages first.
2733 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2735 Fix the 2.4 resource limitation workaround introduced in 1.26 which
2736 actually broke things on mips32, sparc32, and Alpha platforms.
2738 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2739 (which is required by the newer libintl libraries).
2744 Fixed various gcc -Wall complaints.
2746 Fixed a few memory leaks in the e2fsck journaling code, and in the
2747 ismounted code checking for a swap device.
2749 Add new inode I/O abstraction interface which exports an inode as
2752 Exported ext2_file_flush as a public interface.
2754 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
2756 Lots of small random portability fixes to make e2fsprogs build under
2757 AIX --- even without the 5L compatibility toolkit, and even using the
2758 uber-crippled AIX native C compiler.
2761 E2fsprogs 1.26 (February 3, 2002)
2762 =================================
2764 Dumpe2fs will keep going now if the bad block inode can't be read.
2765 (Previously it stopped with a fatal error.)
2767 E2fsck will now give an opportunity to run the journal even if the
2768 recovery flag is not set. This is the default behaviour if e2fsck is
2769 using a backup superblock, since the needs_recovery flag will never be
2770 set in the backup superblock copies.
2772 E2fsck now automatically finds the backup superblock/group descriptors
2773 even when the primary superblock is completely destroyed for 2k and 4k
2774 filesystems. (Previously it just guessed/assumed that we were dealing
2775 with a 1k filesystem in that case, and users had to manually specify
2776 the backup superblock number.)
2778 Fixed a bug in e2fsck where it dereferences a null pointer when there
2779 is a problem opening a filesystem in preen mode.
2781 E2fsck now handles external journals correctly; previously it trashed
2782 the external journal device if the journal needed to be replayed.
2784 Work around ulimit incompatibility problem caused by recent 2.4
2785 kernels; the unix IO module will automatically try to set any resource
2786 limits to be infinite on startup.
2788 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
2789 bitmap if it wasn't present and the blocksize was 2k or 4k.
2790 (Addresses Debian Bug #116975)
2792 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
2793 clearing the new V2 fields if they do not make sense or if the ext3
2794 superblock is version 1 superblock.
2796 E2fsck will automatically relocate the ext3 journal from a visible
2797 file (i.e., /.journal) to an hidden inode if the filesystem has been
2798 opened read/write. This allows the users to add a journal while the
2799 filesystem is mounted, but the next time the system is rebooted, the
2800 journal file will disappear. This avoids problems with backups,
2801 stupid operators with superuser bits, etc.
2803 Fix a bug in fsck where it would not support a filesystem type of
2804 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
2806 Fsck now supports fstab entries of the form "ext3,ext2". It will also
2807 automatically identify reiserfs filesystems.
2809 The number of processes spawned by fsck can now be limited using the
2810 FSCK_MAX_INST environment variable.
2812 Fsck now searchs the LVM proc hierarchy to find logical volumes which
2813 should be searched for UUID and label information.
2815 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
2816 limit if at all possible, when opening a block device. (The filesize
2817 limit shouldn't be applied against writes to a block device.)
2819 In mke2fs and e2fsck, specifying the -c option twice will now do
2820 a read/write test on the disk. Update the man pages to encourage
2821 using the -c option, and to discouraging running badblocks separately,
2822 since users tend to forget to set the blocksize when running
2825 Mke2fs now automatically clears the immutable attribute on a
2826 pre-existing .journal file left over from a previous failed attempt to
2827 add a journal to an alreadyy-mounted filesystem.
2829 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
2832 Mke2fs now creates the lost+found directory with permissions of 0700,
2833 so that files that had previously lived in protected directory are
2834 safe if they get dropped in lost+found and the system administrator
2835 doesn't deal with immediately. (Addresses Debian #bug 118443)
2837 Mke2fs and e2fsck (and all programs that use the
2838 ext2fs_check_if_mounted function) will now properly identify that a
2839 device is mounted, even in cases where devfs has confused things with
2840 multiple devices names with the same identity, or if a dim-witted
2841 system administrator has done something stupid like creating device
2842 file aliases in their home directory. Also now checks for swap devices
2843 by using /proc/swaps. (Addresses Debian bug #106622)
2845 Added a new option (-T) to tune2fs which sets the time a filesystem
2848 Speed up e2image when creating sparse raw image files by optimizing
2849 away excess lseek() system calls.
2851 Fix support of large (> 2GB) files when used as a filesystem in
2852 mke2fs, tune2fs, debugfs, and findsuper.
2854 Debugfs's stat and icheck commands now properly deals with large (>
2857 Debugfs's set_super_value command now prints out the list of valid
2858 superblock fields which can be set using the command.
2860 Debugfs's rm and kill_file command now updates the superblock free block
2861 and inode counts, thus keeping the filesystem consistent.
2863 Debugfs's lsdel command now takes an optional argument which allows
2864 the user to only see the most recently deleted files.
2866 A new command (undel) was added to debugfs which automates
2867 undeleting a deleted inode and linking it back to a directory.
2869 Debugfs's ls command now takes a new option, -d, which lists
2870 deleted directory entries.
2872 Debugfs's testb, freeb, setb, and find_free_block commands now take an
2873 optional count argument.
2875 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
2876 be used to signal that a particular inode should not be eligible for
2877 tail-merging --- this is needed for programs like LILO.
2879 The findsuper (an unreleased, uninstalled utility program) has been
2880 improved to add extra validity checks and to add a progress meter.
2881 (It is still an unsupported program; the officially supported way to
2882 recover from a trashed partition table is to use gpart; findsuper is
2883 for wizards only. :-)
2885 Debugfs was fixed to compile with "configure --disable-swapfs".
2887 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
2889 Added new translation file for Turkish.
2894 Fix general gcc -Wall complaints.
2896 E2fsprogs (mostly) works with the dietlibc.
2898 The programming texinfo file has been expanded to include description
2899 of additional libext2fs functions. (Still not compeltely done, but a
2900 lot of the more important functions have been documented.)
2902 Added a umask structure to struct_ext2_filsys, which currently only
2903 modifies the behaviour of ext2fs_mkdir(), but if we add any file
2904 creation functions to libext2fs, we should also make sure they respect
2907 The build-rpm script was fixed to be a bit more safe.
2909 The tests' Makefile now has a way of automating test case creation
2910 for e2fsck, using "make testnew".
2912 Created a new function, ext2fs_dir_iterate2 which passes more
2913 information to the callback function (identical to the one used by
2914 ext2fs_dblist_dir_iterate). The directory iterator functions take a
2915 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
2916 directory entries. If the directory entry is deleted, the callback
2917 function will be called with the entry paraemter set to
2918 DIRENT_DELETED_FILE.
2920 Added new functions, ext2fs_inode_alloc_stats and
2921 ext2fs_block_alloc_stats, which takes updates block/inode allocation
2922 statistics in the bitmaps, block group descriptors, and superblock
2923 when inodes or blocks are allocated or deallocated.
2926 E2fsprogs 1.25 (September 20, 2001)
2927 ===================================
2929 This is primarily a bug-fix release; no new features were added, but
2930 there are a number of embarassing bug fixes and cleanups applied.
2932 Fix a bug mke2fs which causes stack garbage to be written to disk when
2933 zapping disk sectors. (This bug could cause mke2fs to core dump for
2934 some kernels, I suspect with security enhancement patches.)
2936 Remove unneeded #include of <linux/config.h> which was breaking
2937 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
2939 Updated tune2fs man page to reflect the fact that adding or removing a
2940 journal doesn't require running e2fsck.
2942 Remove use of AC_REQUIRE from autoconf which had been used to prevent
2943 AC_CANONICAL_HOST from being called twice; unfortunately this causes
2944 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
2945 used outside of autoconf macros. Fortunately, it doesn't seem to be
2946 necessary any more, anyway.
2948 E2fsck will now not fall back to an alternate superblock if the user
2949 specifies the superblock location explicitly on the command-line.
2950 This allows easier recovery from a situation where the primary
2951 superblock and block groups are slightly corrupted, but the backup
2952 superblocks are completely broken.
2954 Fix problem which caused compile_et and mk_cmds to blow up if
2955 e2fsprogs was in a directory with a pathname that contained spaces.
2957 We are now more paranoid about checking the entry in /etc/mtab to make
2958 sure the filesystem is really mounted, since some broken distributions
2959 (read: Slackware) don't initialize /etc/mtab before checking non-root
2960 filesystems. (Slackware also doesn't check the root filesystem
2961 separately, and reboot if the root filesystem had changes applied to
2962 it, which is dangerous and broken, but there's nothing I can do about
2965 Make UUID library C++ friendly by adding appropriate extern "C"
2966 declarations and using const in the function declarations.
2968 Fix up the com_err texinfo file so that it can product a valid info
2969 file (previously, it could only be used to generate paper
2970 documentation using texinfo.tex).
2973 E2fsprogs 1.24a (September 2, 2001)
2974 ===================================
2976 Fix brown-paper bug in mke2fs which caused it to segfault when
2977 printing the version string.
2980 E2fsprogs 1.24 (August 30, 2001)
2981 ================================
2983 Revert the BLKGETSIZE64 support, since for some distributions, this
2984 ioctl has been used by an unofficial kernel patch to update the last
2985 sector on the disk, and this was causing disk corruption problems as a
2988 Mke2fs is now more careful about zapping swap space signatures and
2989 other filesystem/raid superblock magic values so that programs like
2990 mount who try to use hueristics to determine the filesystem type of a
2991 partition are less likely to be confused.
2993 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
2994 regular file (since Andreas Dilger's on-line resizing tools will set
2997 Fixed some minor texinfo, man pages nits for spelling errors,
2998 texinfo warnings, etc. (Addresses Debian bug #110621.)
3000 E2fsprogs program no longer print the filesystem version number
3001 (i.e. 0.5b), since it only confuses people and doesn't serve any real
3004 E2fsck will once again compile under libc5, since it will supply its
3005 own version of strnlen if necesssary.
3007 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
3008 when specifying the external journal device. tune2fs will also search
3009 devices looking for the externla journal debice when removing.
3011 E2fsprogs 1.23 (August 15, 2001)
3012 ================================
3014 Add initial support for extended attributes (EA); e2fsck will
3015 correctly handle a filesystem with EA's and check the EA blocks for
3018 E2fsck's symlink sanity checking has been cleaned up. It now checks
3019 the i_size value of fast symlinks, and checks for immutable flags
3020 being set of symlinks, etc.
3022 E2fsck now offers to clear inodes which are special files that have a
3023 non-zero i_blocks or i_size field. (The i_size field check was in the
3024 previous version of the code, but due to a bug it didn't offer to
3025 clear the inode unless i_size and i_size_high were both non-zero.)
3027 E2image can now create "raw" image files, which only contain the
3028 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
3029 debugfs, etc., can be run directly on the raw image file.
3031 Add support for the 64-bit block device patches.
3033 Fixed bugs in creating external journals with a 1k blocksize.
3035 Add initial support for external journals (so long as the external
3036 journal only supports a single filesystem) in e2fsck.
3038 Remove requirement for needing to run fsck on a filesystem after
3039 removing a journal (either internal or external).
3041 The man pages now document how to create and manage external journals.
3043 Speed up the check of an ext3 filesystems by avoiding a needless flush
3044 of all of the superblock and block group descriptors.
3046 Speed up creating an internal journal using tune2fs in the case where
3047 the filesystem has a lot blocks already allocated.
3049 Tune2fs has been fixed to make sure that only error messages go to
3050 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
3052 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
3053 now not set the sparse_super feature. (Addresses Debian bug #108165)
3055 Add support in fsck for the filesystem type "auto".
3057 Fsck -A will not try to interpret device names for filesystems which
3058 have a pass number is 0. (Addresses Debian bug #106696).
3060 Fsck prints a warning message if now valid filesystems are passed to
3061 it. (Addresses Debian Bug #107458.)
3063 E2fsck now gives an explicit warning if there filesystem still has
3064 errors at the end of the run. (Addresses Debian bug #104502)
3066 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
3067 reflects an error. E2fsck will also not run the orphan list if the
3068 filesystem contains errors, since the orphan list might be corrupted.
3070 E2fsck now prints the number of large files when given the -v option.
3072 Fixed minor memory leaks in e2fsck.
3074 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
3077 E2fsprogs 1.22 (June 22, 2001)
3078 ==============================
3080 Fixed a bug in e2fsck's handling of orphan inodes which are special
3081 files (i.e., block/character device files, named FIFO's, etc.).
3083 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
3084 tune2fs to fail at adding a journal to a mounted filesystem.
3086 Fixed a few big-endian bugs in e2fsprogs
3087 * The directory block functions were accidentally reporting
3088 some directories as corrupted when they weren't.
3089 * If e2fsprogs is compiled --disable-swapfs, the C language
3090 equivalents weren't being included for big-endian platforms.
3091 (Fixes Debian bug #101686).
3093 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
3098 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
3099 ioctls, and allow them to be defined for non-i386 platforms.
3101 The uuid.h header file is now protected against multiple inclusions.
3103 E2fsprogs is now being developed using BitKeeper. Changed the test
3104 scripts to deal with BK's stripping CR characgters from text files,
3105 and changed the top-level Makefile.in to avoid including BitKeeper
3106 files when generating the source tarball.
3109 E2fsprogs 1.21 (June 15, 2001)
3110 ==============================
3112 Added new configure flags which allow a subset e2fsprogs to be built;
3113 this is most useful for boot floopies, since the resulting shared
3114 libraries and programs are slimmed down by removing features that
3115 aren't necessary for a boot floppy. The new flags that were added
3116 are: --disable-swapfs, which removes support for byte swapping old
3117 legacy PPC/68k filesystems, --disable-debugfs, which removes support
3118 for debugfs from the libext2fs library, --disable-imager, which
3119 removes support for the e2image program, and --disable-resizer, which
3120 removes support for resize2fs.
3122 E2fsck now prints the number of mounts or days elapsed since the last
3123 check when e2fsck is forced to check an otherwise clean filesystem.
3125 Tune2fs now prints an informative message about how often a filesystem
3126 will be checked when adding a journal to the filesystem, to remind the
3127 user that he/she may want to adjust those parameters using tune2fs
3130 Worked around hurd brain-damage which causes e2fsck to sometimes
3131 believe a filesystem is the root filesystem based on device numbers
3132 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
3135 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
3136 erroneous error with the -F option was specified.
3138 Fixed a ext3 recovery bug in the revoke handling; synchronized with
3141 Fixed two bugs in e2fsck's handling of dup block handling, dealing
3142 with relatively uncommon edge cases: a directory with an indirect
3143 block which is claimed by another file, and when the last inode in the
3144 filesystem has blocks claimed by another file.
3146 E2fsck now checks to see if the i_size field of a fast symlink is too
3147 big, and offers to clear the symlink if so.
3149 E2fsck now checks to see if i_size_high of special files is non-zero,
3150 and offers to clear i_size_high.
3152 Fix e2fsck's handling of incompatible journal flags so that the user
3153 has chance to abort, and then has the option to clear out the journal
3154 entirely. (Addresses Debian bug #98527.)
3156 Fixed a bug in fsck which could cause it to core dump if a mix of
3157 standard and non-standard device names are used in /etc/fstab.
3158 (Debian bug #100559)
3160 Fixed a bug in debugfs which caused read errors when copying a file to
3163 The debugfs set_super_value command can now modify the s_lastcheck field.
3165 Fixed a bug in lsattr and chattr which was accidentally introduced in
3166 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
3167 directories correctly because the change modified the layout of struct
3168 dirent to be incompatible with the libe2p shared library.
3170 Cleaned up the mke2fs manual page and included a discussion about why
3171 it's good to periodically check the filesystem even when journaling is
3177 Fix general gcc -Wall complaints.
3179 The types needed by the ext2 header files are now provided by
3180 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
3182 Integers are now preferred to longs when trying to find a 32-bit type
3183 in ext2_types.h. Also, if linux/types.h has already been defined,
3184 don't try to redefine the types.
3186 Fixed make depend script so that it automatically corrects the
3187 pathname cleanups performed by make -M, so I don't have to fix them up
3190 Fixed the d_loaddump test case to be more robust, and not depend on
3193 Removed debugfs's dependence on pread(), which was accidentally
3194 intrudced in e2fsprogs 1.20
3196 Fixed a performance bug in the libext2fs's icount routine; the size
3197 estimate of the icount array was incorrectly being calculated.
3199 Removed use of the badblocks compatibility functions in the e2fsprogs
3202 Added paranoia code which protects against strange cases where /etc
3203 isn't on the root filesystem, or if /etc/mtab doesn't exist.
3205 The header file ext2_types.h is now installed.
3207 Autoconf is used to determine when we are on big-endian machines,
3208 instead of doing run-time tests, to save a few bytes of code.
3210 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
3211 functions are no longer inline functions, which saves space and
3212 doesn't really cost any real performance.
3214 The ext2fs library no longer depends on the e2p library. (What need
3215 there was of it --- namely, fsetflags, was coded in-line).
3217 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
3218 when the user is stupid and tries compiling the package using "make
3221 Miscellaneous code cleanups:
3222 * Added missing files from Makefile.in's SRCS file, so that
3223 their dependencies would be properly calculated.
3224 * Removed redundant code
3225 * Fixed comments in code
3226 * Removed no-longer unneeded argsused #pragma.
3229 E2fsprogs 1.20 (May 20, 2001)
3230 =============================
3232 Add support for replaying the ext3 journal purely in user mode,
3233 including handling the orphaned inode list. Used code contributed by
3234 Andreas Dilger, with bug fixes and the orphaned inode handling done
3237 The mke2fs and tune2fs programs can create or modify a filesystem to
3238 include an ext3 journal. Tune2fs also can be used to remove an ext3
3239 journal from a filesystem.
3241 E2fsck will now check for the existence of a linked list of orphan
3242 inodes in the superblock, and clear those inodes before starting the
3243 rest of the filesystem check (but after the journal playback).
3245 E2fsck now validates the file descriptor passed to the -C option,
3246 which saves against the completion bar getting written to an
3247 unexpected location, such as the disk being checked. (Debian
3248 bug/wishlist #55220)
3250 E2fsck will now bump the filesystem revision number from zero to one
3251 if any of the compatibility bits are set.
3253 Fixed a bug where a badly corrupted directory on a big endian system
3254 could cause e2fsck to die with a bus error. The
3255 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
3256 the ext2 library now does alignment sanity checks on the rec_len field
3257 of the directory entry before using it.
3259 The ext2 library has been enhanced to make tune2fs safe to run on
3260 mounted filesystems. (Users could usually get away with using tune2fs
3261 on mounted filesystems before, but with the advent of ext3 and
3262 journaling, it became important to make tune2fs was *really* safe for
3263 use even when the filesystem being modified is mounted.) E2label is
3264 now implemented by tune2fs using an argv[0] dispatch, so that e2label
3265 is also now safe for use on mounted filesystems.
3267 Added a new program, e2image, which creates a backup of critical ext2
3268 filesystem data structures. The generated image file can be examined
3269 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
3270 the image file to help recover very badly damaged filesystems.
3272 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
3273 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
3274 large file when deciding whether or not the filesystem has large files.
3276 Fixed lsattr and chattr so that they work correctly on large files.
3277 (Fixes Debian bug #72690.)
3279 Removed limitation in get_device_size() which imposed a one terrabyte
3280 filesystem limitation. (Most 2.2 kernels still have a signed int
3281 problem which cause 1 TB block device limitation. Fortunately, the
3282 kernel patches to fix this are much easier than fixing the 2TB
3283 limitation in the kernel. :-)
3285 A max_mount_count of zero is now treated as if no mount count were
3286 set. (Previously, no mount count was indicated by using -1, and a
3287 mount count of zero caused e2fsck to always be run.)
3289 Mke2fs supports two new filesystem types largefile and largefile4.
3291 Mke2fs now adds some randomness in s_max_mount_count so that multiple
3292 filesystems won't be all checked at the same time under normal
3295 Fixed bug in the progress bar printing code which could cause e2fsck
3296 to core dump on an illegal filesystem.
3298 Fixed bug in fsck which could allow more than one instance of e2fsck
3299 to be printing a progress bar. (Debian bug #65267)
3301 Fsck using a UUID or a LABEL specifier will work even if devfs is
3302 compiled into the kernel and not mounted. If the pathnames in
3303 /proc/partitions are incorrect, fsck will search /dev for the correct
3304 device (using the new ext2fs_find_block_device library function).
3305 Fsck now also checks the RAID devices first so that they are properly
3306 found when they are in use. Support has also been added to support
3307 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
3309 Fixed a bug in fsck which caused it not deal properly with 16
3310 byte long filesystem labels.
3312 Fsck's -t option has been made a lot more flexible. The semantics for
3313 what happens if a comma-separated list to fsck has been regularized,
3314 and it is now possible to filter what filesystems will get checked
3315 based what is in the filesystem's fstab entry's option field. (Debian
3318 The dumpe2fs program can now print out the group description
3319 information in hex, and also prints the location of the superblock and
3320 block group descriptor for those block groups that have them.
3322 Mke2fs now clears the ext2 superblock before it starts creating a
3323 filesystem, so that the superblock magic number is only written if the
3324 filesystem creation process successfully completes.
3326 The debugfs program's stat command now pretty-prints the blocks used
3327 by an inode so that it's more compact and informative.
3329 The debugfs stats command now uses the same libe2p code (which is used
3330 by dumpe2fs) to print the superblock header information. This is more
3331 complete, and it avoids a bit of code duplication.
3333 Added a new debugfs command, set_super_value (ssv) which allows the
3334 user to set arbitrary superblock fields.
3336 Debugfs was extended to support inode numbers in hex (by prefixing
3337 them with 0x), and so that modify_inode can set the inode generation
3338 number. Also, there is now a new function command called logdump
3339 which will dump an ext3 journal.
3341 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
3344 Debugfs's dump command now stops immediately upon reporting a disk
3345 read error. (Fixed a bug in ext2fs_file_read library routine which
3346 caused debugfs not to stop.) (Debian bug #79163)
3348 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
3349 checked before /etc/mtab is used, since /proc/mounts is more likely to
3352 Added portability fixes for Solaris and Linux/ia64.
3354 Various manual pages were clarified and cleaned up. (Fixed debian
3355 bugs #63442, #67446, and #87216)
3361 The e2fsck message printer now supports %Iu and %Ig, which will print
3362 out the inode's user and group owners, respectively.
3364 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
3365 that no longer dependent on the system having the correct version of
3366 the kernel header files.
3368 Added a new function to libext2, ext2fs_find_block_device(), which
3369 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
3370 device given its device number.
3372 Added a new function to libext2, ext2fs_sync_device, which centralizes
3373 all of the places which might try to use the BLKFLSBUF or FDFLUSH
3374 ioctls (and usually failing to define them since the system header
3375 files don't usually do this for us, and we're trying to avoid usage of
3376 kernel include files now).
3378 Added new utility programs in tests/progs: random_exercise and
3379 hold_inode. They aren't built by default; they're useful for
3380 exercising ext3 filesystem code.
3382 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
3383 the filesystem close functions to only update the superblock, and to
3384 not touch the block group descriptors. Needed by tune2fs when
3385 modifying a mounted filesystem.
3387 Got rid of struct ext2fs_sb and replaced it with the standard struct
3388 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
3389 source (but not binary) compatibility of some users of the ext2
3390 library. Those applications should just simply do a global search and
3391 replace of struct ext2fs_sb with struct ext2_super_block, and include
3392 the new header file <ext2fs/ext2_fs.h> which defines it.
3394 The ino_t type has been renamed ext2_ino_t to protect applications
3395 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
3396 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
3397 unexpected ABI change.
3399 The Makefiles have been reworked so that "make check" can be run from
3400 the top-level Makefile.
3402 Fix general gcc -Wall complaints and removed dead code.
3404 Remove use of NOARGS, because we assume everyone does ANSI C these
3407 Added build-rpm script from sct.
3409 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
3412 New function ext2fs_flush_icache which must be called if the
3413 application program modifies the inode table blocks without going
3414 through ext2fs_write_inode() interface.
3416 New ext2fs_check_mount_point() function, which will return the mount
3417 point of a device if mounted.
3419 The io_channel abstraction now has an optional interface,
3420 io_channel_write_range, which allows specific byte ranges to be
3423 The unix_io IO channel now supports write-through caching, so that
3424 journal creation is more efficient.
3426 Added x86 assembly language routines to support byte swapping, to
3427 reduce executable size.
3429 Fixed bug in the utility program subst so that it's possible to
3430 replace a substitution variable with a zero-length string.
3432 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
3433 slipped into some of the problem number.
3435 E2fsprogs 1.19 (July 13, 2000)
3436 ==============================
3438 Release the resize2fs program since the timeout before it could
3439 be released under the GPL has finally expired.
3441 Add experimental support needed for the ext2 compression patches.
3442 This requires compiling e2fsprogs with the --enable-compression flag
3443 to the configure script.
3445 Added ext3 journalling support. E2fsck will run the journal (if
3446 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
3447 installed as a symlink to e2fsck. Fsck has been taught about ext3,
3448 and treats it the same as ext2 in terms of the progress bar logic.
3449 Dumpe2fs will display the superblock journaling information if the
3450 filesystem has a journal. The ext2 library will now permit opening an
3451 ext3 filesystem with the recovery flag set. This is necessary for
3452 on-line dump's to work correctly, but there may be issues with this
3453 working well since ext3 is much less agressive about syncing blocks to
3454 the filesystem, since they're safe on the journal.
3456 Tune2fs and e2fsck have been changed to allow the mount_count check to
3457 be disabled by setting max_mount_count to -1. (This was already
3458 supported by the kernel.)
3460 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
3461 are used for ext3 as well.
3463 Added internationalization support for e2fsprogs; must be enabled
3464 by passing --enable-nls to configure.
3466 Always use the provided ext2fs header files to insulate ourselves from
3467 kernel version changes. Which include files are used by e2fsprogs
3468 have also been cleaned up to improve portability.
3470 Limit the number of times that e2fsck updates the progress bar so that
3471 people who are booting using a 9600 baud console don't get swampped by
3474 Improved the loop detection algorithm in e2sck's pass #3 so that it is
3475 much, much faster for large filesystems with a large number of
3478 The memory footprint for e2fsck is now slightly smaller than before.
3480 E2fsck now checks if special devices have a non-zero size, and offers
3481 to clear the size field if it finds such an inode.
3483 E2fsck now checks if special devices have the append-only flag set,
3484 and offers to clear the inode.
3486 E2fsck now properly handles some "should never fail" cases during a
3487 bitmap copy in pass5.
3489 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
3491 E2fsck now calculates the correct location of the backup superblock in
3492 the case of filesystem blocksizes > 1k.
3494 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
3495 which normally didn't cause problems under most filesystem parameters,
3496 but could cause a valid superblock to be rejected in extreme cases.
3497 Other checks for validating superblock values were made more
3500 Added non-destructive write testing to the badblocks program, courtesy
3501 of David Beattie. The badblocks also now has an option to input the
3502 current set of bad blocks, so that known bad blocks are skipped to
3503 speed up the badblocks test. There is also a persistent rescan
3504 feature which causes badblocks to run until it has completed some
3505 number of passes without discovering any new bad blocks.
3507 Badblocks now checks to see if the device is mounted and refuses to do
3508 the tests involving writing to the device if it is mounted. Also,
3509 badblocks now allows the number of blocks to be checked to be
3510 defaulted to the size of the partition.
3512 Fixed a bug in fsck which didn't allow non-root users to be able to
3513 check filesystems if there were any LABEL= or UUID= entries in
3516 The Hurd doesn't support the filetype filesystem feature. The mke2fs
3517 program now makes sure that for the Hurd, the filestype feature is
3518 turned off. E2fsck will check to see if the filetype feature is
3519 turned on for Hurd filesystems, and offer to turn off the feature.
3521 Mke2fs now has a safety check to make sure the number of blocks do not
3522 exceed 32 bits even on a 64 bit platform.
3524 Really fixed a bug in fsck to allow "fsck -As" to run interactive
3525 fsck's. (For those people who like to do interactive fsck's in the
3528 Debugfs has a few new features: the rdump command, which will do a
3529 recursive dump of a directory and all of its contents, and the lcd
3530 command which does a local chdir (much like the ftp command of the
3531 same name). In addition, the debugfs program and the open_filesystem
3532 command now takes three new options: -b and -s, which allows the
3533 blocksize and superblock location to be specified, and the -c option
3534 which is used in catastrophic situations where the block group
3535 descriptors are corrupt. If the -c option is specified, debugfs will
3536 skip trying to read in the block and inode bitmaps.
3538 Debufs's lsdel command was fixed to handle bad blocks in the inode
3541 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
3544 General improvements in error messages
3546 - Mke2fs prints a sane error message if the partition size is zero
3547 (usually because the partition table wasn't reread by the
3548 kernel due to the partition being busy), instead of "invalid
3549 argument passed to ext2 library while initializing superblock".
3551 - Fsck now prints more self-explanatory message if an invalid UUID=
3552 or LABEL= specification is passed to it.
3554 UUID library changed to use the LGPL.
3556 Fixed a bug in the UUID library where very rapid calls to the
3557 time-based UUID generator could cause duplicate UUID's to be returned.
3558 This was not a problem for e2fsprogs, but it could be a problem for
3559 other users of the library.
3561 Make the UUID library more robust in the face of missing or an
3562 improper /dev/urandom or /dev/random files.
3564 Added some random portability fixes for Solaris.
3566 Some minor man page updates.
3568 Fixed a memory leak in the ss library.
3574 We now try to use lseek64 and open64 from the LFS if possible.
3576 The 3rd parameter in e2p's print_flags is now a flags word, instead of
3579 The mark and unmark bitmap functions now return the previous state of
3580 the bit that was being changed, which is useful for some speed
3583 The following functions have been added to enhance the badblocks list
3584 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3585 ext2fs_badblocks_equal.
3587 The ext2 header files now have the latest journalling fields to the
3590 The ext2fs_mkdir function in libext2fs now properly backs out of error
3591 conditions robustly.
3593 Cleaned up makefiles:
3594 - to cleanly compile with the -j flag.
3595 - so distclean removes all generated files.
3596 - so in case of an error while installing header files, the make aborts.
3598 Fix test_script so that it works correctly when compiling in the
3601 The random UUID generation routine has been made slightly better in
3602 the case where /dev/random doesn't exist. (Use of randomly-based UUID
3603 is still not recommended if /dev/random doesn't exist, however; it's
3604 better to use the time/ethernet MAC address UUID in this case.)
3606 Clean up the build process so it's more friendly in case of missing
3609 The ext2fs header file can now be #include'd into C++ programs.
3611 The e2p.h header file is now installed.
3613 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3617 E2fsprogs 1.18 (November 10, 1999)
3618 ==================================
3620 Fix a core dumping bug in e2fsck if an imagic inode is present or
3621 (more rarely) if the filesystem is badly corrupted enough that e2fsck
3622 has to restart pass 1 processing. E2fsck now closes the filesystem
3623 before freeing a large number of its data structures, so in the case
3624 of future memory faults, at least the fixed filesystem will be fully
3627 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3628 imagic inode, it will offer to clear the imagic flag.
3630 E2fsck will now offer to clear the immutable flag on special files
3631 (device/socket/fifos) when running it in non-preen mode.
3633 E2fsck will now set the filetype when creating /lost+found, and when
3634 connected orphaned inodes to /lost+found.
3636 Debugfs's ncheck and icheck commands now handles the case where there
3637 are bad blocks in the inode table without bombing out.
3639 The badblocks list processing code has been made more efficiently for
3640 appending a large number of (ordered) badblocks to the badblocks list.
3642 Some minor man page updates.
3644 Fsck now allows interactive e2fsck's when using fsck -As (not a common
3645 mode, but some people like to do this in boot scripts for silly reasons).
3650 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3651 with the problem code convention.
3653 The badblocks list regression test program has been updated to work
3654 with previously made API name changes.
3656 The ext2fs_free() command now uses the new badblocks API to avoid
3657 using the compatibility layer.
3659 Added new regression test cases; the run_e2fsck test script now
3660 supports the ability for a test case to run a prepratory command
3661 before running e2fsck.
3663 E2fsprogs 1.17 (October 26, 1999)
3664 =================================
3666 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3669 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3670 thus potentially causing problems if a binary UUID contained a NULL
3673 E2fsck now uses stricter checks for directory entries in pass 2:
3674 zero-length filenames are not allowed; neither are 8 byte long
3677 The debugfs "dirty" command now clears the filesystem valid bit.
3678 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
3679 bit in the in-core superblock image. The new functionality is more
3680 what the user expects, and is more useful.)
3682 Added a debugging hook to test parallel fsck; if the environment
3683 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3684 will be checked in parallel when they normally would not be.
3689 Fixed some #ifdef's for compilation under the Hurd OS.
3691 Fixed minor W2K compatibility problems.
3693 Fixed some miscellaneous GCC warnings.
3696 E2fsprogs 1.16 (October 22, 1999)
3697 =================================
3699 Fixed a race condition bug in fsck; when printing a progress bar, if
3700 checking multiple filesystems in parallel, it was possible for fsck to
3701 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3702 handler, which would cause it to terminate with a signal 10.
3704 E2fsck now properly handles filesystems that have the
3705 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3706 filesystem into using or not using FILETYPE feature.
3708 E2fsck now properly handles filesystems that have the IMAGIC feature
3709 turned on (this is used on Linux AFS servers).
3711 The mke2fs program now creates filesystems that have the filetype and
3712 sparse_superblock features enabled by default, unless it is run on a
3713 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3714 so there is now a new flag -O which allows the user to specify with
3715 which features she would like to create the filesystem; "mke2fs -O
3716 none" will create a filesystsem compatible with 2.0 kernels.
3718 The tune2fs program now has a -O option which allows the user to set
3719 and reset "safe" filesystem features. Currently, the only ones which
3720 allows to be modified are the filetype and sparse_superblock features.
3721 Note setting or clearing either feature will require running e2fsck on
3722 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3723 requires that there is enough free space on the filesystem for the
3724 extra superblocks which will be created by e2fsck.)
3726 Debugfs can now set and print filesystem features in the superblock
3727 using the "features" command. Dumpe2fs will print out the complete
3728 set of features when listing the superblock.
3730 Dumpe2fs has new options -f (force) and -h (header-only).
3732 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3733 message to come up. This could happen when decrementing or
3734 incrementing a link count could result in an overflow.
3736 Fixed a bug in e2fsck where the block count on the lost+found
3737 directory would not be properly incremented when the directory was
3738 expanded to the point where an indirect block needed to be allocated.
3740 E2fsck now makes some additional sanity checks on the superblock to
3741 avoid crashing or giving a memory allocation error if some of the
3742 values in the superblock are unresonable (but the superblock otherwise
3745 Fixed a bug in e2fsck where a very badly corrupted filesystem might
3746 require two passes to completely fix the filesystem. This happened if
3747 an inode claimed blocks that was part of the filesystem metadata
3748 (typically, when garbage was written into an inode table or indirect
3749 block, since this kind of filesystem corruption normally doesn't
3752 On the Alpha, glibc declares st_flags although it isn't actually used;
3753 the configure script was improved to detect this case so that
3754 e2fsprogs can avoid using the non-functional stat field.
3756 The manual pages were updated to use a more consistent formatting
3757 style consistent with standard Unix man pages. Mke2fs's man page
3758 added documentation for a few previously undocumented options.
3760 Fixed minor display bugs in tune2fs and mke2fs.
3765 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
3767 Added features to parse and print feature strings into the e2p library.
3768 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
3770 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
3771 whose directory entries contain proper filetype information if the
3772 filesystem supports it.
3774 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
3775 the directory entry filetype information. This is used to set the
3776 directory entry filetype information if the filesystem supports it.
3778 Fixed a bug in ext2fs_expand_dir() where the block count in a
3779 directory's inode would not be properly incremented when the directory
3780 was expanded to the point where an indirect block needed to be
3784 E2fsprogs 1.15 (July 18, 1999)
3785 ==============================
3787 Add configuration checks so that e2fsprogs will compile cleanly on
3788 Linux 2.3 kernels that have renamed i_version to i_generation.
3790 E2fsck now prints a progress/completion bar (and not just a simple
3791 spinner) if the -C0 option is requested or if it receives a SIGUSR1
3792 signal. Fsck will automatically manage the (potentially muliple)
3793 e2fsck processes to print completion bars if it is given a -C option,
3794 with the right thing happening if multiple filesystems are being
3795 checked in parallel.
3797 Mke2fs now has better automatic hueristics to determine the filesystem
3798 parameters to be used for a particular filesystem. Added a new option
3799 -T which allows the user to specify how the filesystem is to be used,
3800 which helps mke2fs do a better job selecting the filesystem parameters.
3802 Mke2fs now creates revision 1 filesystems by default, and with the
3803 sparse superblock feature enabled. The sparse superblock feature is
3804 not understood by Linux 2.0 kernels, so they will only allow read-only
3805 mounts of filesystems with this sparse superblocks.
3807 Fix bug where if /dev/null couldn't be opened (should never happen),
3808 e2fsck would hang in a tight loop.
3810 Make e2fsck handle the case where /lost+found isn't a directory.
3812 E2fsck now uses mallinfo if it exists to get accurate statistics about
3815 Fix bug in e2fsck where it wouldn't check to see if a disconnected
3816 inode had any problems before connecting it to /lost+found.
3818 Add check to e2fsck so it makes sure that total number of inodes in
3819 the filesystem is a sane number.
3821 Fix fencepost error when clearing an the end of the block bitmap which
3822 caused the last block in the bitmap not to get cleared.
3824 Cleaned up a number of messages in e2fsck:
3825 * The message "Group's #'s copy of the group descriptor..."
3826 was fixed so that the correct number would be displayed.
3827 * Added missing space in the "disk write-protected" error messsage
3828 * Cleaned up the error message printed when a non-interactive
3829 e2fsck needs to abort a check because the filesystem
3830 appears to be mounted.
3832 Added a new command-line utility, uuidgen, which will create and print
3835 Make debugfs's icheck command more robust by checking to make sure an
3836 inode has valid blocks before interarting over the inode's blocks.
3838 UUID generation now uses a random-based scheme whenever possible to
3839 prevent potential privacy problems.
3841 Man pages for all of the UUID functions in the lirbary were added.
3843 Fixed bug in fsck so it won't coredump if a filesystem not in
3844 /etc/fstab is given to it.
3846 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
3847 that most of the other mount utilities understands.
3849 Mke2fs will make a filesystem even if it appears mounted if the force
3852 Dumpe2fs has new command-line options which allow a filesystem expert
3853 to specify the superblock and blocksize when opening a filesystem.
3854 This is mainly useful when examining the remains of a toasted
3857 The badblocks program has been updated to display correctly on disks
3858 with large block numbers.
3860 The badblocks program no longer gives spurious errors when errors
3861 occur on non-block boundaries, which is common if the blocksize is
3864 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
3865 MKE2FS_SYNC environment variable is set. This is to work around a VM
3866 bug in the 2.0 kernel. I've heard a report that a RAID user was able
3867 to trigger it even using a 2.2 kernel, but hopefully it will not be
3868 needed for most Linux 2.2 users.
3870 Fixed miscellaneous documentation and man pages.
3875 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
3876 in e2fsck's pass1.c really should have been static.
3878 The return value of the uuid_compare() function was changed to make it
3879 match with the convetions used by strcmp, memcmp, and Paul Leach's
3880 UUID sample document.
3882 The "make depend" process has now been made more automated; it now
3883 automatically word-wraps the dependencies, and only replaces source
3884 Makefile.in if there has been a change in the dependencies. Also, a
3885 top-level "make depend" now recurses through all the subdirectories
3888 The Makefile in .../util has been changed so that subst is built using
3889 the native C compiler during a cross-compilation, since the subst
3890 program is only used during the build process. Also add an explicit
3891 rule to build util/subst by cd'ing to the correct directory and
3894 The man directories are defined in terms mandir, so that the configure
3895 script can override the location of the manual pages.
3897 The config files have been updated to recognize new machine types for
3898 both the i386 and alpha families.
3900 Fsck has been modified so that it will accurately create an
3901 fsck_instance even when the noexecute flag is set. This allows for
3902 accurate debugging of the fsck pass structure. Also, when the verbose
3903 flag is given twice, fsck will print debugging information about when
3904 fsck is waiting for jobs to finish.
3907 E2fsprogs 1.14 (January 9, 1999)
3908 ================================
3910 Fix the fstab parsing code so that it can handle blank lines and
3911 comment characters. Also, missing pass numbers need to be treated as
3914 Fixed a bug in e2fsck where under some circumstances (when e2fsck
3915 needs to restart processing after fixing an egregious inconsistency)
3916 it would try to access already freed memory.
3918 E2fsck now prints non-printable characters in directory entries and
3919 pathnames using '^' and 'M-' notation.
3921 Fixed chattr so that it will ignore symbolic links when doing
3922 recursive descent traversals. For both chattr and lsattr, no longer
3923 print the version string unless the -V option is given.
3925 Allow the system administrator to directly specify the number of
3926 inodes desired in the filesystem, for some special cases where this is
3929 Fix portability problems so that e2fsprogs can be compiled under Linux
3930 1.2 systems and Solaris systems.
3932 Update the config.guess file with a more recent version that will
3933 identify newer Linux platforms.
3938 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
3939 an inode number of zero is passed to them.
3941 E2fsprogs 1.13 (December 15, 1998)
3942 ==================================
3944 Fixed a bug in debugfs where an error messages weren't getting printed
3945 when the ext2 library routines to read inodes returned errors in the
3946 stat, cmri and rm commands.
3948 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
3949 provided, it won't create an inode table smaller than the minimum
3950 number of inodes required for a proper ext2 filesystem.
3952 Fsck now parses the /etc/fstab file directly (instead of using
3953 getmntent()), so that it can distinguish between a missing pass number
3954 field and pass number field of zero. This caused problems for
3955 diskless workstations where all of the filesystems in /etc/fstab have
3956 an explicit pass number of zero, and fsck could not distinguish this
3957 from a /etc/fstab file with missing pass numbers.
3959 E2fsck will create a /lost+found directory if there isn't one in the
3960 filesystem, since it's safer to create the lost+found directory before
3963 Fixed e2fsck so that it would detect bogus immutable inodes which
3964 happen to be sockets and FIFO files, and offer to clear them.
3966 If a filesystem has multiple reasons why it needs to be checked, and
3967 one of the reasons is that it is uncleanly mounted, e2fsck will print
3968 that as the reason why the filesystem is being checked.
3970 Cleaned up the output routines of mke2fs so that it doesn't overflow
3971 an 80 column display when formating really big filesystems.
3973 Added a sanity check to e2fsck to make sure that file descriptors 0,
3974 1, 2 are open before opening the hard disk. This avoids a problem
3975 where a broken program might exec e2fsck with those file descriptors
3976 closed, which would cause disastrous results if the kernel returns a
3977 file descriptor for the block device which is also used by FILE *
3980 Fixed up the e2fsck progress reporting functions so that the values
3981 reliably reach 100% at the completion of all of the e2fsck passes.
3983 Fixed minor documentation bugs in man pages and usage messages.
3988 Fixed a number of lint warnings in the ext2fs library and potential
3989 portability problems from other OS's header files that might define
3990 CPP macros for names like "max" and "min".
3992 ext2fs_badblocks_list_add() has been made more efficient when it needs
3993 to grow the bad blocks list.
3995 Fixed a bug in e2fsck which caused it to dereference a freed pointer
3996 just before exiting.
3998 Fixed the substition process for generating the mk_cmds and compile_et
3999 scripts so that they will work outside of the build tree.
4001 Add sanity check to e2fsck so that if an internal routine
4002 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
4003 and causing a core dump. This should never happen, but...
4005 E2fsprogs 1.12 (July 9, 1998)
4006 ==================================
4008 E2fsprogs now works with glibc (at least with the version shipped wtih
4009 RedHat 5.0). The ext2fs_llseek() function should now work even with
4010 i386 ELF shared libraries and if llseek() is not present. We also
4011 explicitly do a configure test to see if (a) llseek is in libc, and
4012 (b) if llseek is declared in the system header files. (See standard
4013 complaints about libc developers don't understand the concept of
4014 compatibility with previous versions of libc.)
4016 The ext2fs library now writes out the block group number in each of
4017 the superblock copies. This makes it easier to automatically
4018 determine the starting block group of the filesystem when the block
4019 group information is trashed.
4021 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
4022 which means that e2fsprogs will ignore the high 8 bits of the
4023 directory entry's name_len field, so that it can be used for other
4026 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
4027 E2fsprogs will now support filesystems with 64-bit sized files.
4029 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
4031 Added new program "e2label", contributed by Andries Brouwer. E2label
4032 provides an easy-to-use interface to modify the filesystem label.
4034 Fixed bug so that lsattr -v works instead of producing a core dump.
4036 Fixed a minor bug in mke2fs so that all groups with bad superblock
4037 backup blocks are printed (not just the first one).
4039 Mke2fs will check the size of the device, and if the user specifies a
4040 filesystem size larger than the apparent size of the device it will
4041 print a warning message and ask if the user wants to proceed.
4043 E2fsck has a new option -C, which sends completion information to the
4044 specified file descriptor. For the most part, this is intended for
4045 programs to use, although -C 0 will print a spinning character to the
4046 stdout device, which may be useful for users who want to see something
4047 happening while e2fsck goes about its business.
4049 Fixed a bug in e2fsck which could cause a core dump when it needs to
4050 expand the /lost+found directory, and sometimes the bitmaps haven't
4051 been merged in. Also fixed a related bug where ext2fs_write_dir_block
4052 was used to write out a non-directory block. (Which would be bad on a
4053 non-Intel platform with byte swapping going on.)
4055 Fixed bug in e2fsck where it would print a "programming error" message
4056 instead of correctly identifying where a bad block was in used when
4057 the bad block was in a non-primary superblock or block group
4058 descriptor. Also fixed a related bug when sparse superblocks are in
4059 use and there is a bad block where a superblock or block group
4060 descriptor would have been in a group that doesn't include a
4063 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
4064 the block group descriptor table is corrupt, it was possible to try to
4065 allocate a huge array, fail, and then abort e2fsck.
4066 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
4067 and subsitutes reasonable values if the descriptors are obviously bogus.
4069 If e2fsck finds a device file which has the immutable flag set and the
4070 i_blocks beyond the normal device number are non-zero, e2fsck will
4071 offer to remove it, since it's probably caused by garbage in the inode
4074 When opening a filesystem, e2fsck specially checks for the EROFS error
4075 code, and prints a specific error message to the user which is more
4078 If the filesystem revision is too high, change the e2fsck to print
4079 that this is either because e2fsck is out of date, or because the
4080 superblock is corrupt.
4082 E2fsck now checks for directories that have duplicate '.' and '..'
4083 entries, and fixes this corruption.
4085 E2fsck no longer forces a sync of the filesystem (with attendant sleep
4086 calls) at all times. The ext2fs_flush() function now performs a sync
4087 only if it needed to write data blocks to disk.
4089 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
4090 certain errors would not be properly reported.
4092 Updated and expanded a few points in the man pages which users
4093 complained wheren't explicit enough.
4095 Added special case byte-swapping code if compiling on the PowerPC, to
4096 accomodate the strange big-endian variant of the ext2 filesystem that
4097 was previously used on the PowerPC port.
4103 Removed C++ keywords from the ext2fs libraries so that it could be
4106 E2fsck's internal organization has now been massively reorganized so
4107 that pass*.c don't have any printf statements. Instead, all problems
4108 are reported through the fix_problem() abstraction interface. E2fsck
4109 has also been revamped so that it can be called as a library from a
4112 Added new fileio primitives in libext2fs for reading and writing
4113 files on an unmounted ext2 filesystem. This interface is now used by
4116 Added a new libext2fs function for mapping logical block numbers of
4117 a file to a physical block number.
4119 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
4120 a block, zeros it, and updates the filesystem accounting records
4123 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
4124 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
4126 The libext2fs functions now use a set of memory allocation wrapper
4127 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
4128 instead of malloc, free, and resize. This makes it easier for us to
4129 be ported to strange environments where malloc, et. al. aren't
4130 necessarily available.
4132 Change the libext2fs fucntion to return ext2-specific error codes
4133 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
4134 and depending on the existence of system error codes (such as EEXIST
4137 Renamed io.h to ext2_io.h to avoid collision with other OS's header
4140 Add protection against ext2_io.h and ext2fs.h being included multiple
4143 The types used for memory lengths, etc. have been made more portable.
4144 In generla, the code has been made 16-bit safe. Added Mark
4145 Habersack's contributed DOS disk i/o routines.
4147 Miscellaneous portability fixes, including not depending on char's
4150 The io_channel structure has a new element, app_data, which is
4151 initialized by the ext2fs routines to contain a copy of the filesystem
4154 ext2fs_check_directory()'s callback function may now return the error
4155 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
4156 really do the checking, despite the presence of the callback function.
4159 E2fsprosg 1.11 (June 17, 1997)
4160 ==============================
4162 Fixed e2fsck to detect (previously ignored) conflicts between the
4163 superblock or block group descriptors and block bitmaps, inode
4164 bitmaps, and inode tables.
4166 Fixed bug in e2fsck so that when the message printed out when a block
4167 or inode bitmap conflicts with other data, it has the correct group
4170 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
4171 to badblocks. This meant that not all of the filesystem was being
4172 tested for bad blocks!
4174 Fixed an array boundary overrun case which cropped up in
4175 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
4178 Adjusted the number of columns printed by mke2fs when displaying the
4179 superblock backups to avoid running over 80 columns when making a
4180 really big filesystem.
4182 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
4183 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
4184 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
4189 Fixed install rule in lib/ss so that ss_err.h is actually getting
4192 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
4193 bassed back to the caller.
4195 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
4196 setting the current inode number (which meant this function wasn't
4199 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
4200 blocks in the bitmap when increasing the size of the bitmap.
4202 Changed the initial number of blocks allocated by ext2fs_init_dblist()
4203 to be more realistic.
4205 Added a new function ext2fs_allocate_group_table, which sets up the
4206 group descriptor information (and allocates inode and block bitmaps,
4207 and inode tables for a particular group). The function was created by
4208 factoring out code form ext2fs_allocate_tables().
4210 Added a new function ext2fs_move_blocks which takes a bitmap of the
4211 blocks to be moved, and moves them to another location on the
4214 Make the unix_io channel's io_channel_flush implementation calls sync()
4215 to to flush the kernel buffers to disk.
4217 Added a new function ext2fs_dblist_count returns the number of
4218 directory blocks in dblist.
4221 E2fsprogs 1.10 (April 24, 1997)
4222 ===============================
4224 Mke2fs once again defaults to creating revision #0 filesystems, since
4225 people were complaining about breaking compatibility with 1.2 kernels.
4226 Warning messages were added to the mke2fs and tune2fs man pages that
4227 the sparse superblock option isn't supported by most kernels yet (1.2
4228 and 2.0 both don't support parse superblocks.)
4230 Added new flag to mke2fs, -R <raid options>, which allows the user to
4231 tell mke2fs about the RAID configuration of the filesystem. Currently
4232 the only supported raid option is "stride" which specifies the width
4235 Fixed bug in e2fsck where pass1b would bomb out if there were any
4236 blocks marked bad in the inode table.
4238 Fixed rare bug in mke2fs where if the user had a very unlucky number
4239 of blocks in a filesystem (probability less than .002) the resulting
4240 filesystem would be corrupt in the last block group.
4242 Fixed bug where if e2fsck tried to allocate a block to fix a
4243 filesystem corruption problem and the filesystem had no free blocks,
4244 ext2fs_new_block() would loop forever.
4246 The configure script now checks explicitly to see if "-static" works,
4247 since that can't be assumed to be true --- RedHat doesn't install
4248 libc-static by default.
4250 Fixed bug in libext2's block iterator functions where under some
4251 cirmcustances, file with holes would cause the bcount parameter to the
4252 callback function to be incorrect. This bug didn't affect any of
4253 e2fsprogs programs, but it was discovered by Paul Mackerras, the
4254 author of the PPC boot loader.
4256 Removed use of static variables to store the inode cache in libext2fs.
4257 This caused problems if more than one filesystem was accessed via
4258 libext2fs (static variables in libraries are generally a bad idea).
4259 Again, this didn't affect e2fsprogs programs, but it was discovered by
4262 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
4263 will compile cleanly with 1.2.13 kernels (even with a.out shared
4269 Added new functions to duplicate an ext2 filesystem handle, and its
4270 associated substructure. New functions: ext2fs_dup_handle(),
4271 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
4272 Other structures, such as the io_channel and the inode_cache, now have
4273 a ref count so that they only get freed when they are no longer used
4274 by any filesystem handle. (These functions were added as part of the
4275 development effort for an ext2 resizer).
4277 E2fsprogs 1.09 (April 14, 1997)
4278 ===============================
4280 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
4281 accidentally introduced in the 1.08 release. The overhead calculation
4282 was accidentally removed, which caused ext2fs_initialize() to not
4283 notice when the filesystem size needed to be adjusted down because
4284 there wasn't enough space in the last block group.
4286 Fixed bug in version parsing library routine; it was always parsing
4287 the library version string, instead of using the passed-in string.
4289 Clarified chattr man page.
4291 E2fsprogs 1.08 (April 10, 1997)
4292 ===============================
4294 E2fsck 1.07 was very slow when checking very large filesystems with a
4295 lot of files that had hard links (i.e., news spools). This was fixed
4296 by seriously revamping the icount abstraction. Added a formal test
4297 suite for the icount abstraction.
4299 Debugfs now has a "-l" option to the "ls" command, which lists the
4300 inode number, permissions, owner, group, size, and name of the files
4303 Fix a bug in e2fsck where when a directory had its blocks moved to
4304 another location during the pass 1b processing, the directory block
4305 list wasn't updated, so pass 2 wouldn't check (and correct) the
4306 correct directory block.
4308 E2fsck will now treat inodes which contain blocks which are claimed by
4309 the filesystem metadata by treating them as multiply claimed blocks.
4310 This way, the data in those blocks can be copied to a new block during
4311 the pass 1b--1d processing.
4313 E2fsck will attempt to determine the correct superblock number and
4314 display it in the diagnostic and warning messages if possible.
4316 Add support for a new (incompatible) feature, "sparse_super". This
4317 feature reduces the number of blocks which contain copies of backup
4318 superblocks and block group descriptors. (It is only an incompatible
4319 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
4320 support a new -s option; e2fsck will recognize filesystems built with
4321 this feature turned on.
4323 E2fsck now checks the library to make sure is the correct version,
4324 using new library functions. (This helps to diagnose incorrectly
4325 installed e2fsprogs distributions.)
4327 Dumpe2fs now prints more information; its now prints the the
4328 filesystem revision number, the filesystem sparse_super feature (if
4329 present), the block ranges for each block group, and the offset from
4330 the beginning of the block group.
4332 Mke2fs now distributes the inode and block bitmap blok so that the
4333 won't be concentrated in one or two disks in RAID/striping setups.
4334 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
4335 choose the largest blocks per group that be chosen. (For 2k blocks,
4336 you can have up to 16384 blocks/group; for 4k blocks, you can have up
4337 to 32768 blocks/group.) Previously mke2fs would not allow
4338 specification of more than 8192 blocks per group, even if you were
4339 using a 2k or 4k block group.
4344 Added a new function ext2fs_create_icount2() which takes a "hint"
4345 argument. This hint argument presets the icount array with the list
4346 of inodes which actually need to be in the icount array. This really
4347 helps to speed up e2fsck.
4349 Added a new function ext2fs_icount_validate() which checks the rep
4350 invariant for the icount structure. This is used mostly for testing.
4352 The error mesasage given when a bad inode number is passed to
4353 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
4354 EXT2FS_UNMARK_ERROR).
4356 Added a new function ext2fs_set_dir_block which sets the block of a
4357 dblist entry, given the directory inode and blockcnt.
4359 Added a new function ext2fs_get_library_version() which returns the
4360 current library version, and ext2fs_parse_version_string() which
4361 returns a version number based on a e2fsprogs version string.
4363 The icount functions will return EINVAL if the passed in inode number
4366 E2fsprogs 1.07 (March 9, 1997)
4367 ==============================
4369 E2fsck is now uses much less memory when checking really large
4370 filesystems (or rather, filesystems with a large number of inodes).
4371 Previously a filesystem with 1 million inodes required 4 megabytes of
4372 memory to store inode count statistics; that storage requirement has
4373 now been reduced to roughly half a megabyte.
4375 E2fsck can now properly deal with bad blocks appearing inside the
4376 inode table. Instead of trying to relocate the inode table (which
4377 often failed because there wasn't enough space), the inodes in the bad
4378 block are marked as in use.
4380 E2fsck will automatically try to use the backup superblocks if the
4381 primary superblocks have a bad magic number or have missing meta-data
4382 blocks (or meta-data blocks which are out of range).
4384 E2fsck's pass 3 has been made more efficient; most noticeable on
4385 filesystems with a very large number of directories.
4387 Completely revamped e2fsck's system of printing problem reports. It
4388 is now table driven, to make them more easily customizeable and
4389 extendable. Error messages which can be printed out during preen mode
4390 are now one line long.
4392 Fixed e2fsck's filesystem swapping code so that it won't try to swap
4393 fast symbolic links or deleted files.
4395 Fixed e2fsck core dumping when fixing a filesystem which has no
4396 directories (not even a root directory).
4398 Added a check to e2fsck to make sure that the length of every
4399 directory entry is a multiple of 4 (since the kernel complains if it
4402 Added a check to e2fsck to make sure that a directory entry isn't a
4403 link to the root directory, since that isn't allowed.
4405 Added a check to e2fsk to now make sure the '.' and '..' directory
4406 entries are null terminated, since the 2.0 kernel requires it.
4408 Added check to write_bitmaps() to make sure the superblock doesn't get
4409 trashed if the inode or block bitmap is marked as being block zero.
4411 Added checking of the new feature set fields in the superblock, to
4412 avoid dealing with new filesystem features that this package wasn't
4415 Fixed a fencepost error in ext2fs_new_block() which would occasionally
4416 try to allocate a block beyond the end of a filesystem.
4418 When the UUID library picks a random IEEE 802 address (because it
4419 can't find one from a network card), it sets the multicast bit, to
4420 avoid conflicting with a legitimate IEEE 802 address.
4422 Mke2fs now sets the root directory's owner to be the real uid of the
4423 user running mke2fs. If the real uid is non-zero, it also sets
4424 the group ownership of the root directory to be the real group-id of
4425 the user running mke2fs.
4427 Mke2fs now has more intelligent error checking when it is given a
4428 non-existent device.
4430 When badblocks is given the -vv option, it now updates the block that
4431 it is currently testing on every block.
4433 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
4434 currently correctly if PATH wasn't already set.
4436 Shared libraries now built with dependencies. This allows the shared
4437 library files to be used with dlopen(); it also makes the transition
4438 to libc 6 easier, since ld.so can tell which libc a particular shared
4439 library expects to use.
4444 Added new abstraction (defined in dblist.c) for maintaining a list of
4445 blocks which belongs to directories. This is used in e2fsck and other
4446 programs which need to iterate over all directories.
4448 Added new functions which test to see if a contiguous range of blocks
4449 (or inodes) are available. (ext2fs_*_bitmap_range).
4451 Added new function (ext2_inode_has_valid_blocks) which returns true if
4452 an inode has valid blocks. (moved from e2fsck code).
4454 Added new function (ext2fs_allocate_tables) which allocates the
4455 meta-data blocks as part of initializing a filesystem. (moved from
4458 Added a new I/O manager for testing purposes. It will either allow a
4459 program to intercept I/O requests, or print debugging messages to
4460 trace the activity of a program using the I/O manager.
4462 The badblocks_list functions now store the bad blocks in a sorted
4463 order, and use a binary search to speed up badblocks_list_test.
4465 The inode scan function ext2fs_get_next_inode() may now return a soft
4466 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
4467 those cases where part of an inode table is missing or there is a bad
4468 block in the inode table.
4470 Added a new function (ext2fs_block_iterate2) which adds new arguments to
4471 the callback function to return a pointer (block and offset) to the
4472 reference of the block.
4474 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
4475 application to jump to a particular block group while doing an inode
4478 The badblocks list functions were renamed from badblocks_* to
4479 ext2fs_badblocks_*. Backwards compatibility functions are available
4480 for now, but programs should be modified to use the new interface.
4482 Some of the library functions were reorganized into separate files to
4483 reduce the size of some programs which statically link against the
4486 Put in some miscellaneous fixes for the Alpha platform.
4489 E2fsprogs 1.06 (October 7, 1996)
4490 ================================
4492 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
4493 smash the backup copies in ext2fs_close(). (The problem was that when
4494 e2fsck -p discovered the problem, while it was closing the filesystem
4495 and exiting, it was also blowing away the backup superblocks on the
4496 disk, which was less than friendly.) We now make it the case that we
4497 only write out the backup superblock and the back block descriptors if
4498 the filesystem is completely free from problems.
4500 Fixed a bug in block_interate in the lib/ext2fs library which caused
4501 e2fsck to fail on GNU Hurd-created filesystems.
4503 Add support for Linux/FT's bootloader, which actually uses
4504 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
4507 Add support for the "A" (no atime update) attribute. (Note: this
4508 attribute is not yet in production kernels.)
4510 The test suite is not automatically run when doing a "make all" from
4511 the top level directory. Users should manually run "make check" if
4512 they wish to run the test suite.
4514 Upon a preenhalt(), make the printed message more explicit that
4515 running e2fsck "MANAULLY" means without the -p or -a options.
4517 In e2fsck, if a disconnected inode is zero-length, offer to clear it
4518 instead of offering to connect it to lost+found.
4520 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
4521 e2fsck to be run over it, change e2fsck to explicitly display this
4524 For dumpe2fs and e2fsck, cause the -V option to print out which
4525 version of the ext2fs library is actually getting used. (This will
4526 help detect mismatches of using a 1.06 utility with a 1.05 library,
4532 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
4533 the naming convention.
4535 In ext2fs_initialize(), make sure the description for the inode bitmap
4536 is correctly initialize.
4538 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4540 E2fsprogs 1.05 (September 7, 1996)
4541 ==================================
4543 Add support for new fields in the ext2 superblock --- volume name,
4544 volume UUID, and last mounted field. Dumpe2fs displays these fields,
4545 tune2fs and mke2fs allows you to set them. E2fsck will automatically
4546 generate a UUID for those volumes that don't have them.
4548 Put in support for e2fsck to recognize HURD specific ext2 features ---
4549 most notably, the translator block. The e2fsprogs tools will now use
4550 the creator_os field in the superblock to correctly handle different
4551 OS-specific variants of the ext2 filesystem.
4553 E2fsck now fixes inodes which have a the deletion time set, but which
4554 have a non-zero i_link_count field by offering to clear the deletion
4555 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4556 ext2 kernel behavior) and offered to unlink the file.
4558 If e2fsck sets the clean bit, but nothing else, set the exit code
4559 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4560 set the filesystem valid bit when it was previously cleared. :-) This
4561 was needed to make the HURD fsck driver happy.
4563 If the user refuses to attach an unattached inode, e2fsck will no
4564 longer set the inode's link count. Otherwise, the inode would end up
4565 getting marked as unused, which might cause loss of data later.
4567 Make the message issued by e2fsck when the superblock is corrupt less
4568 confusing for users. It now mentions that another reason for the
4569 "corrupt superblock" message might be that the partition might not be
4570 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4572 Make the libext2 library more robuest so that e2fsck won't coredump on
4573 an illegal superblock where the blocksize is zero. (f_crashdisk is
4576 By default, create filesystems where the default checkinterval is 6
4577 months (180 days). Linux servers can be robust enough that 20 reboots
4578 can be a long, long time.
4580 Added configure flag --enable-old-bitops, which forces the bitops to
4581 use the old (native) bitmask operations. By default on the sparc
4582 platform, the standard ext2 bit ordering is now used.
4584 Added a new feature to e2fsck to byte-swap filesystems; this can be
4585 used to convert old m68k filesystems to use the standard byte-order
4586 storage for the superblock, inodes, and directory blocks. This
4587 function is invoked by using the '-s' option to e2fsck.
4589 Debugfs's "dump" command has been enhanced so that it writes out the
4590 exact size of the file so that the nulls at the end of the file are
4591 eliminated. The command also accept a new "-p" option which will
4592 attempt preserve to preserve the ownernship, permissions, and
4593 file modification/access times.
4595 Debugfs has two new options, -f and -R. The -R option allows the user
4596 to execute a single debugfs command from the command line. The -f
4597 option allows the user to specify a "command file" containing debugfs
4598 commands which will get executed.
4600 Dumpe2fs now pretty prints the check interval, instead of just
4601 printing the check interval as a number of seconds.
4603 Fix bugs in debugfs: the params command when no filesystem is opened
4604 no longer causes a core dump. It is now possible to unlink a file
4605 when a pathame containing a '/' is specified.
4607 Tune2fs has a new -C option which sets the number of times the
4608 filesystem has been mounted.
4610 Fix the chattr '-v' option so that it actually works. Chattr was
4611 being buggy about the -v option parsing.
4616 The directory lib/uuid contains a set of library routines to generate
4617 DCE compatible UUIDs.
4619 Extended ext2fs_namei() to handle symbolic links. Added new function
4620 ext2fs_nami_follow() which will follow last symbolic link in the case
4621 where the pathname points to a sym link.
4623 The ext2fs_block_iterate function will now return the HURD translator
4624 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4625 iterator to return data blocks only. The ext2fs.h file now defines
4626 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4627 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4628 count field of the iterator callback function.
4630 The test script driver now takes an optional second argument, which is
4631 the test case to be run. This allows you to run a test case without
4632 needing to run the entire test suite.
4634 On Linux ELF systems, install the .so files in the correct places
4635 (/usr/lib). The .so files must be stored in the same directory as the
4638 Fixed miscellaneous HURD compilation issues with header file being
4639 included in the right order.
4641 Fixed debugfs so that it resets optind to zero, not one, since setting
4642 optind to zero is more correct.
4645 E2fsprogs 1.04 (May 16, 1996)
4646 =============================
4648 First "official" (1.03 was a limited release only) to support building
4649 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4652 This package includes a RPM specs file, that it can be built using the
4653 RedHat Package Manager.
4655 E2fsck now prints a hint that if there are lots of incorrectly located
4656 inode bitmaps, block bitmaps, and inode table blocks, the user might
4657 want to try using e2fsck -b 8193 first, to see if that fares any
4660 For ext2 filesystem written with the hurd, debugfs will now print out
4661 the translator field when printing an inode structure.
4663 Lots of miscellaneous linking/installation cleanups:
4665 Libraries are now linked using a relative pathname, instead of
4666 relying on -L working correct. It doesn't, in many cases, including
4667 current versions of GNU ld. This guarantees that the build tree is
4668 linking with the right libraries, instead of the ones installed in
4671 Header files, man pages, and the et/ss shell scripts are now
4672 generated using a custom substitution script, instead of relying on
4673 the configure script. This prevents needless recompilation of
4674 files; in addition, the custom substitution script is much faster.
4676 e2fsck may now be linked dynamically, by using the
4677 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4678 since it increases e2fsck's dependence on other files, but some
4679 people need to save disk space, and other critical programs on their
4680 systems were being linked dynamically anyway.
4682 Programs such as fsck which didn't need to be linked against
4683 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4684 only link against libraries they actually need. Otherwise, those
4685 programs would require the presense of libraries that otherwise
4686 could be removed from a rescuse diskette.
4688 The ss include files are now installed correctly so they can
4689 actually be used by another package.
4691 If the profiling libraries are built, they are now installed on a
4692 "make install-libs".
4695 E2fsprogs 1.03 (March 27, 1996)
4696 ===============================
4698 Change the m68k bit numbering for bitmasks to match the bit numbering
4699 used by all other ext2 implementations. (This change was requested by
4700 the m68k kernel development team.)
4702 Support (in-development) filesystem format revision which supports
4703 (among other things) dynamically sized inodes.
4705 Fixed a bug in the ext2 library so that an intelligent error is
4706 returned if mke2fs is run with a ridiculously small number of blocks
4709 Fixed a bug in the ext2 library which required that the device be
4710 openable in read/write mode in order to determine its size. This
4711 caused e2fsck -n to require read/write access when it was not
4712 previously necessary.
4714 Fixed a bug in e2fsck which casued it to occasionally fail the test
4715 suite depending on which version of the floating point library it was
4718 Fixed a bug in e2fsck so that it now halts with a fatal error when
4719 certain superblock consistency checks fail. Previously it continued
4720 running e2fsck, with some potential confusing/damaging consequences.
4722 Added new flag to fsck which allows the root to be checked in parallel
4723 with other filesytems. This is not the safest thing in the world to
4724 do, but some system administrators really wanted it.
4726 Fixed -Wall flames in lib/ss.
4729 E2fsprogs 1.02 (January 16, 1996)
4730 =================================
4732 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4734 Change e2fsck to print statistics of how many non-contiguous files are
4735 on the system. Note that a file which is larger than 8k blocks, it is
4736 guaranteed to be non-contiguous.
4738 In mke2fs, print a warning message if a user tries to format a whole
4739 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
4740 whole disk, the -F (force) option forces mke2fs to format a whole disk
4743 Fix a bug in fsck where in some cases it might start checking
4744 partitions in the next pass before it finishes checking partitions in
4745 the current pass. This still won't cause two partitions on the same
4746 disk will be checked, so it's rarely a problem in real life.
4748 Patch lsattr so that it won't hang when checking a named pipe.
4750 Minor compilation fixes:
4751 * Fix the order of libraries that were linked in debugfs.
4752 * Allow the sources to be compiled with -ansi turned on.
