1 E2fsprogs 1.40.10 (May 21, 2008)
2 ================================
4 When deciding whether or not to revalidate a blkid cache entry, if the
5 device's mtime is newer than the last time the cached entry was
6 validated, force a revalidation.
8 Fix a potential data corruption bug in e2fsck in the journal replay.
9 The chances of this is happening is extremely remote, especially the
10 default data=ordered or data=writeback modes. However, if a block
11 which has been journalled starts with the first four bytes 0xc03b3998,
12 when e2fsck replays the journal, those four bytes will be replaced
13 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
14 metadata to begin with those fatal 4 byte sequence, and unless
15 data=ordered mode is in use, data blocks are never journaled.
17 Updated German, Dutch, Sweedish, and Vietnamese translations.
22 Fixed various Debian packaging issues --- see debian/changelog for
25 Remove default sizes of types when cross compiling, since autoconf
26 2.50 can figure this out automatically now.
29 E2fsprogs 1.40.9 (April 27, 2008)
30 =================================
32 SuSE's security team audited uuidd and came up with a few minor
33 issues. None of them are serious given that uuidd runs setuid as a
34 unprivileged user which has no special access other than libuuid
35 directory, but it's good to get them fixed.
37 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
38 work correctly with in-inode extended attributes.
40 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
43 Debugfs will avoid using a pager if the standard output is not a tty.
45 Fix debugfs and tune2fs to correctly handle daylight savings time when
46 parsing a time string.
48 Fixed spelling mistakes, typos, and otherwise clarified man pages.
50 Fix fsck completion bars when multiple filesystems were being checked
51 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
52 #203323, Addresses Sourceforge Bug: #1926023)
54 Fix fsck so that progress information is sent back correctly when
55 multiple filesystems are being check and the output of fsck is being
56 redirected to a file descriptor. Also, include the device name (w/o
57 spaces) in the progress information sent back via a file descriptor.
58 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
61 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
63 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
64 signal to its child process.
66 Fix mke2fs's creation of are resize inode when there is a non-standard
67 s_first_data_block setting.
69 Fix bug in blkid when run by an unprivileged user; most devices were
70 not reported correctly. 9Addresses Launchpad Bug: #220275)
72 Mke2fs will not allow the logically incorect combination of
73 resize_inode and meta_bg, which had previously caused mke2fs to create
76 Fix fsck in German locales so that a 'j' means yes.
77 (Addresses Sourceforge Bug: #1947683)
83 Fixed various Debian packaging issues --- see debian/changelog for
86 Update valgrind options in test_script to work with valgrind 3.2.3
88 Update texinfo.tex to a much newer version from the FSF.
90 Remove bashism for configure script and from the lib/ss Makefile.
91 Addresses Sourceforge Bug: 1921969
93 Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
95 Fix build system so that if texinfo is not installed, it won't print a
96 (harmless) error message.
99 E2fsprogs 1.40.8 (March 13, 2008)
100 =================================
102 Fixed e2image -I so it works on image files which are larger than 2GB.
104 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
105 the size is larger than the number of blocks found in the inode, don't
106 try to allocate extra empty blocks at the end of the directory to make
107 up the difference; there's no point to doing that. In addition, if
108 the size is not a multiple of a blocksize, always fix it.
110 E2fsck handled a pass 2 "should never happen error" by not giving
111 enough information and then core dumping. Unfortunately, it was all
112 too easy to trigger the "should never happen" situation if a
113 directory's inode size was not correct. This has been fixed, but
114 e2fsck has also been taught how to handle this situation more
115 gracefully, by simply removing the inode hash tree information, so
116 that it can be rebuilt again after e2fsck's pass 3. (Addresses
117 Launchpad Bug: #129395)
119 Resize2fs had a bug resizing large inodes with extended attributes
120 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
121 completely on big-endian systems such as PowerPC. The bug should be
122 completely fixed now. Yay for regression test suites. (Addresses Red
123 Hat Bugzilla: #434893)
125 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
126 translations. Many thanks to Philipp Thomas from Novell for stepping
127 up to become the new German translation maintainer! (Addresses Debian
128 Bugs: #302512, #370247, #401092, #412882).
130 When e2fsck is clearing a corrupt inode's HTREE directory information,
131 make it clear that it is just clearing the HTREE information, not the
134 Fixed spelling mistakes, typos, and otherwise clarified man pages.
139 Add new functions, ext2fs_dblist_get_last() and
140 ext2fs_dblist_drop_last(), which allows the caller to examine the last
141 directory block entry added to the list, and to drop if it necessary.
143 Fixed a portability problem in libblkid with DJGPP.
145 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
146 to Philipp Thomas for pointing this out.
148 If the info files are not built, change "make install" so it doesn't
149 fail with an error code.
152 E2fsprogs 1.40.7 (February 28, 2008)
153 ====================================
155 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
156 depreciate the -s option, since it can result in filesystems which
157 e2fsck can't fix easily. There are very good reasons for wanting to
158 disable sparse_super; users who wants to turn off sparse_super can use
159 debugfs. (Addresses Sourceforge Bug: #1840286)
161 Add missing options to mke2fs's usage message. (Addresses Sourceforge
164 Fix bug in resize2fs when large (greater than 128 byte) inodes are
165 moved when a filesystem is shrunk; it was only moving the first 128
166 bytes, so extended attributes were not getting moved. (Addresses Red
167 Hat Bugzilla: #434893)
169 E2fsck now prints an explicit message when the bad block inode is
170 updated, to avoid confusion about why the filesystem was modified.
171 (Addresses Sourceforge Bug: #756460)
173 Allow mke2fs and tune2fs manipulate the large_file feature.
174 Previously we just let the kernel and e2fsck do this automatically,
175 but e2fsck will no longer automatically clear the large_file feature.
176 It still isn't really necessary to worry about this feature flag
177 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
180 Suppress message about an old-style fstab if the fstab file is empty.
181 (Addresses Debian Bug: #468176)
183 Fix (really minor) bug in debugfs's find_free_block so it avoids
184 reporting a free block more than once if there are too few free blocks
185 in the filesystem. (Addresses Sourceforge Bug: #1096315)
187 Change e2fsck to no longer clear the LARGE_FILES feature flag
188 automatically, when there are no more > 2GB files in the filesystem.
189 It's been almost a decade since there have been kernels that don't
190 support this flag, and e2fsck clears it quietly without telling the
191 user why the filesystem has been changed.
193 Fix bug which could cause libblkid to seg fault if a device mapper
194 volume disappears while it is being probed. (Addresses RedHat
197 Inhance e2fsck's reporting of unsupported filesystem feature flags.
198 (Addresses Sourceforge Feature Request: #1175808)
200 Fix option syntax in dumpe2fs for explicit superblock and blocksize
201 parameters. What was currently documented in the man page has been
202 broken for some time, due to getopt() implementation changes. The
203 option sytax has been changed to one which is can be more portable
204 supported and which is consistent with the format for extended options
205 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
207 Add support to tune2fs to clear the resize_inode feature. This
208 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
210 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
213 Add support for setting RAID stride and stripe-width via mke2fs and
214 tune2fs. Teach dumpe2fs to print the RAID parameters.
216 Add support for setting new superblock fields to debugfs's
219 Add support for printing "mostly-printable" extended attributes in
222 Add support for the -M option to fsck, which causes it to ignore
225 Fix uuidd so that it creates the pid file with the correct pid number.
226 (Addresses Sourceforge Bug: #1893244)
228 Fix various gcc -Wall warnings.
230 Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
232 Fixed spelling mistakes, typos, and otherwise clarified man pages.
233 (Addresses Sourceforge Patch: #1399325)
239 Fixed various Debian packaging issues --- see debian/changelog for
240 details. (Addresses Debian Bug: #466929)
242 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
243 partially filled-in filesystem object on an error, so that e2fsck can
244 print more intelligent error messages.
246 Add a new function e2p_edit_feature2() which allows the caller to
247 specify which feature flags are OK to set or clear, and which returns
248 more specific information about feature flags which are not allowed to
251 Set the C locale in the test_script driver since it uses [A-Za-z].
252 (Addresses Sourceforge Bug: #1890526)
254 Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
257 Change configure.in to avoid using the 'dc' command unless it is
258 absolutely needed. (i.e., when using parsing a WIP-style version
259 number) (Addresses Sourceforge Bug: #1893024)
261 Add portability checks to support compilation under DJGPP.
263 Update to the latest samba tdb code before the LGPLv3 change, which
264 fixes a realloc() leak on failure.
266 Fix memory leak in ext2fs_alloc_block().
268 Fix makefile dependency issues for various install targets.
269 (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
271 Improve descriptions for the r_move_itable and r_resize_inode tests.
274 E2fsprogs 1.40.6 (February 9, 2008)
275 ===================================
277 Add support for returning labels for UDF filesystems in the blkid
280 Fix bug in the blkid library where cached filesystems was not being
281 flushed when opening USB devices returned the error ENOMEDIUM.
282 (Addresses Debian Bug: #463787)
284 Added logic to the blkid library to automatically choose whether a
285 filesystem should be mounted as ext4 or ext4dev, as appropriate.
287 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
289 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
290 configured with --enable-jbd-debug.
292 Document the BLKID_FILE environment variable in the libblkid man page
297 Update e2fsprogs translation template and Vietnamese and Czech translations
299 Fixed various Debian packaging issues --- see debian/changelog for
300 details. (Addresses Debian Bugs: #436058)
302 Don't try to create $DESTDIR/etc/init.d as part of make install as we
303 don't install the init.d script (and it's not the recommended way to
304 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
306 Use thread local storage to fix a theoretical race condition if two
307 threads try to format an unknown error code at the same time in the
311 E2fsprogs 1.40.5 (January 27, 2008)
312 ===================================
314 Fix a potential overflow big in e2image if the device name is too
317 Mke2fs will now create new filesystems with 256 byte inodes and the
318 ext_attr feature flag by default. This allows for much better future
319 compatibity with ext4 and speeds up extended attributes even on ext3
322 Teach e2fsck to ignore certain "safe" filesystem features which are
323 set automatically by the kernel. Having the kernel set features
324 automagically behind the user's back is a bad idea, and we should try
325 to break the kernel of this habit, especially for the newer ext4
326 feature flags. But for now, we will try to avoid needless full checks
327 which can annoy users who are doing fresh installs.
329 Add support in tune2fs and mke2fs for making a filesystem as being "ok
330 to be used with test kernel code". This will be needed for using test
331 filesystems with the latest ext4 kernel code.
333 Change e2fsck -fD so that it sorts non-htree directories by inode
334 numbers instead of by name, since that optimizes performances much
335 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
337 If e2image fills the disk, fix it so it exits right away instead of
338 spewing large numbers of error messages.
339 (Addresses-Sourceforge-Feature-Request: #606508)
341 If ftruncate64() is not available for resize2fs, let it use ftrucate()
342 instead, but have it check to see if the size would get truncated, and
343 skip calling ftruncate in that case.
345 Add support for detecting HFS+ filesystems in the blkid library.
347 Add supprt in the blkid library for ext4/ext4dev filesystems.
349 Fix a bug in blkid where it could die on a floating point exception
350 when presented with a corrupt reiserfs image.
352 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
353 such that UUID string is a fixed length.
355 Add sample python bindings for the uuid library to the contrib
356 directory. (Addresses-Sourceforge-Patches: #778817)
358 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
359 will work with large files. (Addresses Sourceforge Feature Request:
360 #1257500 and Sourceforge Support Request: #1253511)
362 Allow the debugfs 'undel' command to undelete an inode without linking
363 it to a specific destination directory, since this might require
364 allocating blocks that could overwrite some yet-to-be-recovered
365 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
367 Update Swedish translations from the Translation Project.
372 Fix configure handling of --sbindir (which should rarely be used, but
373 someone did complain, so let's fix it). (Addresses Sourceforge Bug:
376 Updated e2fsprogs.spec file to include a new uuidd package
378 Use pkg-config to determine where to find the devmapper library so we
379 can find out where it is located on different distributions.
381 Fix Makefile race so that "make -j3 distclean" works correctly
383 Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
384 especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
387 Fixed spelling mistakes, typos, and otherwise clarified man pages.
389 Fixed various Debian packaging issues --- see debian/changelog for
390 details. (Addresses Debian Bugs: #459403, #459475, #459614)
392 Remove the --enable-dynamic-static configure option, and build e2fsck
393 dynamically by default. If the user wants e2fsck.static, he/she will
394 need to build it via "make -C e2fsck e2fsck.static"
396 Fix various build warnings due to missing prototypes.
397 (Addresses Sourceforge Patch: #1861663, #1861659)
400 E2fsprogs 1.40.4 (December 31, 2007)
401 ====================================
403 Improve time-based UUID generation. A new daemon uuidd, is started
404 automatically by libuuid if necessary. This daemon is setuid to allow
405 updates to /var/lib/libuuid, so the clock sequence number can be
406 stored and so if the clock is set backwards, it can be detected.
407 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
410 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
411 superblocks. This avoids e2fsck from concluding that a full
412 filesystem check is required before backing up the superblock due to
413 changes in the feature flags. (Addresses Debian Bug: #454926)
415 Fix fsck to only treat the '#' character as a comment at the beginning
416 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
417 will cause fsck to issue an bogus warning message.
418 (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
420 Format control characters and characters with the high eighth bit set
421 when printing the contents of the blkid cache, to prevent filesystems
422 with garbage labels from sending escape sequences to the user's screen
423 that might, for example place it in graphics mode. (Addresses Ubuntu
426 Fix sign-extension problem on 64-bit systems in in the com_err
427 library. (Addresses Sourceforge Bug: #1809658)
429 Avoid division by zero error when probing an invalid FAT filesystem in
430 the blkid library. (Addresses Sourceforge Bug: #1831627)
432 Update Dutch, Polish, and Vietnamese translations from the Translation
433 Project. Remove the Rwandan translation upon advice of the
439 Fix the libss "make check" regression test so that it works if the
440 current directory is not in the user's path or if the libss shared
441 library is not installed. (Addresses Sourceforge Bug: #1848974)
443 Fixed spelling mistakes, typos, and otherwise clarified man pages.
444 (Addresses Debian Bugs: #444883, #441872)
446 Fixed various Debian packaging issues --- see debian/changelog for
447 details. (Addresses Debian Bugs: #437720, #451172, #458017)
449 Fix build failure on non-Linux/non-Hurd/non-Masix systems.
450 (Addresses Sourceforge Bug: #1859778)
452 Fix Hurd portability issues. (Addresses Debian Bug: #437720)
455 E2fsprogs 1.40.3 (December 5, 2007)
456 ===================================
458 Fix a potential security vulnerability where an untrusted filesystem
459 can be corrupted in such a way that a program using libext2fs will
460 allocate a buffer which is far too small. This can lead to either a
461 crash or potentially a heap-based buffer overflow crash. No known
462 exploits exist, but main concern is where an untrusted user who
463 possesses privileged access in a guest Xen environment could corrupt a
464 filesystem which is then accessed by the pygrub program, running as
465 root in the dom0 host environment, thus allowing the untrusted user to
466 gain privileged access in the host OS. Thanks to the McAfee AVERT
467 Research group for reporting this issue. (Addresses CVE-2007-5497.)
469 Fix hueristics in blkid which could cause a disk without partitions to
470 be incorrectly skipped when a loopback device is present. (Addresses
471 Red Hat Bugzilla #400321.)
473 Fix e2image so that in raw mode it does not create an image file which
474 is one byte too large.
476 Change mke2fs's usage message so it recommends the preferred -E option
477 instead of the deprecated -R option.
479 Enhance the blkid library so it will recognize squashfs filesystems.
480 (Addresses Red Hat Bugzilla #305151.)
482 Enhance e2fsck so it will force the backup superblocks to be backed up
483 if the filesystem is consistent and key constants have been changed
484 (i.e., by an on-line resize) or by e2fsck in the course of its
487 Enhance blkid's detection of FAT filesystems; so that USB disks with
488 only a single bootable partition will not get missed.
490 E2fsck will no longer mark a filesystem as invalid if it has time
491 errors (i.e., if superblock mount time or last write time is in the
492 future) and the user refuses to fix the problem.
494 The Ubuntu init scripts don't properly set the system time correctly
495 from hardware clock if the hardware clock is configured to tick local
496 time instead of GMT time. Work around this as best as we can by
497 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
498 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
501 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
502 Hat Bugzilla #151533.)
504 Fix e2fsck so that if the superblock is corrupt, but still looks
505 vaguely like an ext2/3/4 superblock, that it automatically tries to
506 fall back to the backup superblock, instead of failing with a hard
509 Make the e2fsprogs program more robust so that they will not crash
510 when opening a corrupt filesystem where s_inode_size is zero.
512 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
513 arguments are detected as such and the parse error is reported to the
514 user. (Addresses Debian Bug #435381.)
516 Change e2fsck so it will not complain if a file has blocks reallocated
517 up to the next multiple of a system's page size.
519 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
520 about (valid) filesystems where the inode table extends to the last
521 block of the block group. (Addresses Red Hat Bugzilla #214765.)
523 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
524 allocating inode tables for some relatively rare odd disk sizes.
525 (Addresses Red Hat Bugzilla #241767.)
527 Add Catalan translation and update Dutch and Swedish translations
528 from the Translation Project.
530 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
531 still had an issue when trying to figure out whether we need to
532 byte-swap fast symlinks that contained extended attributes.
534 Fixed spelling mistakes, typos, and otherwise clarified man pages.
535 (Addresses SourceForge Bug #1821333.)
541 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
543 Add "make check" to the RPM spec file
545 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
546 works correctly when the prefix is not the root directory.
548 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
549 clena up after themselves by deleting the test.img temporary file
550 after completing the test.
552 Fixed a corner case bug ext2fs_unlink() when trying to delete the
553 first directory entry in a directory block and the last directory
554 entry in the previous directory block is not in use. Fortunately
555 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
556 places where it is extremely unlikely to run into this corner case.
558 Fix missing dependency which would cuase parallel builds to fail.
559 (Addresses Sourceforge Bug #1842331.)
561 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
562 calling open(O_CREATE) with a missing mode parameter.
564 Fix the test_ss.c in lib/ss so it can be used as an example
565 application program for the library as well as a regression test
568 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
569 are properly passed back up through the call stack.
571 E2fsprogs 1.40.2 (July 12, 2007)
572 ================================
574 A recent change to e2fsck_add_dir_info() to use tdb files to check
575 filesystems with a very large number of filesystems had a typo which
576 caused us to resize the wrong data structure. This would cause a
577 array overrun leading to malloc pointer corruptions and segfaults.
578 Since we normally can very accurately predict how big the the dirinfo
579 array needs to be, this bug only got triggered on very badly corrupted
582 Fix a bug in e2fsck which caused it to incorrectly salvange
583 directories when the last entry's rec_len is bogusly too big. This
584 resulted in a nonsense filesystem corruption to be reported, and
585 required a second run of e2fsck to fully fix up the directory.
587 Update tune2fs man page to include more discussion of reserved blocks
588 (Addresses Launchpad bug #47817)
590 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
594 E2fsprogs 1.40.1 (July 7, 2007)
595 ===============================
597 Fix bug which could cause libblkid to loop forever. When revalidating
598 a partition where there is obsolete information in /etc/blkid.tab, we
599 end up freeing a the type tag without clearing dev->bid_type, causing
600 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
602 The Turkish translation has a bug in it where it has the translation
603 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
604 @E, recursively, forever, until the stack fills up and e2fsck core
605 dumps. We fix this by making e2fsck stop @-expansions after a
606 recursive depth of 10, which is far more than we need.
607 (Addresses Sourceforge Bug: #1646081)
609 Compile the default mke2fs.conf into mke2fs program. People are
610 getting surprised by mke2fs creating filesystems with different
611 defaults than earlier versions of mke2fs if mke2fs.conf is not
612 present. So we now create a built in version of mke2fs.conf file
613 which is used by mke2fs if the /etc/mke2fs.conf is not present.
614 (Addresses SourceforgeBug: #1745818)
616 Improve the config/parse_types.sh helper script. Fix a potential
617 security problem if e2fsprogs is built as root (as Gentoo does!). In
618 addition fix the script and how it is called from the configure script
619 so that it does the right thing when cross-compiling. (Fixes Gentoo
622 Update Vietnamese, French, and Dutch PO files from the Translation
623 Project. Also created a new e2fsprogs.pot file for translator.
625 Fix bogus strip permission errors when building under Debian. When
626 building the e2fsprogs dpkg's, the dh_strip command emits a large
627 number of error messages caused by the permissions not being right.
628 So run dh_fixperms before running dh_strip.
633 Add new function: profile_set_default(). This function sets the value
634 of the pseudo file "<default>". If the file "<default>" had
635 previously been passed to profile_init(), then def_string parameter
636 will be parsed and used as the profile information for the "<default>"
639 Fix mk_cmds's error reporting so that it is unambiguous that it is the
640 mk_cmds script which is generating the error. (Obviates Gentoo patch:
641 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
643 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
644 priority" environment variable that overrides all others, where as
645 LANG is the lowest priorty environment variable. If LC_ALL is set, it
646 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
647 the all the rest are set. This will assure that the locale when
648 running the test suites is the "C" locale. (Obviates Gentoo patch:

655 Fix divide by zero error in blkid's NTFS probing logic.
657 Add new blkid -g option which causes the blkid cache to be garbage
660 Fix a bug in libblkid which could cause the internal field bid_type to
661 become corrupted. Fortunately bid_type isn't used much, and bid_label
662 and bid_uuid is only used by debugging code, so the impact of this bug
665 Mke2fs will now store the RAID stride value when a filesystem is
666 created with a requested RAID stride, and then use it automatically in
669 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
670 isn't too big. In some cases Lustre users have tried specifying an
671 inode size of 4096 bytes, while keeping an inode ratio of one inode

675 superblock, so that it won't accidentally find a superblock that was
676 located in the journal, and then later reject it as being not a valid
679 Fix e2fsck get_size logic so that it will work with the Linux floppy
680 driver. The Linux floppy driver is a bit different from the other
681 block device drivers, in that if the device has been opened with
682 O_EXCL, it disallows another open(), even if the second open() does
683 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
685 Fix error checking of badblock's last-block and start-block arguments.

704 Fix e2fsck so that it updates the journal inode if it is corrupted and
705 the backup journal information from the superblock was successfully
706 used to recover the filesystem.
708 Fix e2fsck so that it checks all of the blocks in the journal inode
709 for validity. The original code only checked the direct blocks to
710 make sure the journal inode was sane. Unfortunately, if some or all
711 of the indirect or doubly indirect blocks were corrupted, this would

716 Add extra sanity checks for extended attributes in the case where the
717 size is zero but the offset is very large.

723 the top-level COPYING file (Red Hat Bugzilla: 166058)
725 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
727 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
729 Remove check in e2fsck which requires EA's in inodes to be sorted;
730 they don't need to be sorted, and e2fsck was previously wrongly
731 clearing unsorted EA's stored in the inode structure.
733 Allow mke2fs or tune2fs to create a substantially larger journal (up
734 to 10,240,000 blocks).
736 Fix MD superblock detection, and make sure the correct UUID is
737 reported from the MD superblock.
739 Fix a signed vs. unsigned bug in debugfs.
741 Enhance debugfs's date parser so that it accepts integer values.
743 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
744 file with multiply claimed blocks is hard linked. or not at all if the
745 root directory contains shared blocks
747 Enhance debugfs so it can modify the block group descriptors using the
748 command set_block_group_descriptor.

772 field on the first pass.
774 Fix e2fsck to set the file type of the '..' entry when connecting
775 a directory to lost+found. (Addresses Lustre Bug: #11645)
777 Enhance e2fsck to recover directories whose modes field were corrupted
778 to look like special files. This is probably only useful in
779 artificial test cases, but it will be useful if we ever do the "inodes
780 in directory" idea for ext4.
782 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
785 Fix resize2fs parsing of size parameter (in sector units). This was
786 actually a bug in libe2p's parse_num_blocks() function. When handling
787 the 's' suffix, it was ignoring the blocksize information passed in
788 from the caller and always interpreting the number in terms of a 1k
789 blocksize. (Addresses Debian Bug: #408298)
791 There was a floating point precision error which could cause e2fsck to
792 loop forever on really big filesystems with a large inode count.

795 Fix memory leak in ext2fs_write_new_inode()
797 Add support for using a scratch files directory to reduce e2fsck's
798 emory utilization on really big filesystems. This uses the TDB
799 library. See the [scratch_files] section of the e2fsck.conf man page
802 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
803 platform (Addresses Debian Bug: #397044)

808 Allow debugfs and dumpe2fs to support fs features under development.
810 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
811 ext2fs_open() , which allows application to open filesystes with features

815 SourceForge Bug: #1547922)
817 Fixed overflow and signed/unsigned problems caused by the number of
818 blocks or inodes exceeding 2**31 or being close to 2**32-1.

821 superblock to fix cross-architectural portability for htree
822 directories with filenames where the high 8th bit is set. (Addresses

829 Require mke2fs -F -F for really dangerous operations, since -F is
830 needed for less dangerous operations such as creating filesystems
831 images in regular files, or creating filesystems on whole block

833 with running mke2fs on an apparently-mounted or in-use filesystem.
835 Allow the default inode size to be specified into the mke2fs.conf

847 Fix debugfs display bug us that bytes that have the high bit set are
848 displayed as "ec" instead of "ffffffec".
850 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
852 Device mapper scanning wasn't working in the blkid library because the
853 pathnames had an extra "/dev" when they were being probed.
855 Add GFS/GFS2 support to the blkid library.
857 Fix blkid support of empty FAT filesystem labels.
859 Avoid recursing forever (or for a long time) when the blkid library
860 searches for a device and there are symlinks to directories in /dev.
862 Avoid unaligned halfword access in blkid when accessing FAT
863 superblocks, as this will cause Sparc/Solaris systems to throw a

873 the superblock. Omit by default printing superblocks that are likely
874 found in located in an ext3 journal unless an explicit -j option is

878 translation. (Addresses Debian bug: #411562)
880 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
881 determining a partition's size, since binary searching to determine
882 the device doesn't work on FreeBSD.
884 Documentation about UUID's is available in enough places, and it's
885 awkward to deal with debian-legal's insanities. So I'm caving in the
886 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
887 don't have do the dfsg tarball. Also remove the rule that only tried
888 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
889 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
891 Fix the info-dir line so that the menu name does not contain a .info
892 prefix. First of all, it's ugly, secondly, it causes the install-info

912 (Addresses Sourceforge Bug: #1565561)
914 Remove unused variables and other lint/gcc -Wall cleanups
916 Add check to ext2fs_get_device_size() so it will return EFBIG for for
917 filesystems contained in regular files where the filesystem image size
918 is returned by stat64().
920 Set local environment variables to C so mk_cmds and compile_et always
921 work. (Addresses SourceForge Bug: #1532177)
923 Added the 64-bit byte swapping function ext2fs_swab64().
925 Added two new helper functions to prevent 2**31/2**32-1 overflow
926 problems: ext2fs_div_ceil() and e2p_percent().
928 Create new ext2fs library inline functions ext2fs_group_first_block()
929 and ext2fs_group_last_block() in order to calculate the starting and
930 ending blocks in a block group.
932 Create the generated files read-only to remind developers not to edit them.
934 Add support for autoconf 2.60 (with backwards compatibility for older
935 versions of autoconf).
937 Added an "make rpm" target to top-level Makefile
939 Added various FreeBSD portability fixes.
941 Exclude mercurial files from the RPM build tree to speed up copy/build.
943 Use root_sysconfdir to define the locations of mke2fs.conf and
944 e2fsck.conf instead of using a hard-coded /etc pathname.
946 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
948 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
950 If diff -u is supported, use it to report test failures.
952 Updates/improvements to RPM spec file
954 Add on-disk format definitions for the following new features:
955 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
956 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
957 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE

960 reruns any failed tests
962 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
964 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
965 pointer dereferences, memory leaks, etc. None were security-criticial
968 Fix up usage and decrement error messages in the test_icount program
970 Add debugging code to the com_err library; if the environment variable
971 COMERR_DEBUG is set to 1, print out debugging messages as error tables
972 are added and removed from the com_err library. If the
973 COMERR_DEBUG_FILE environment variable is set (and the process is not
974 setuid) the debugging messages may be redirected to a file.
976 Change all of the e2fsprogs programs to use the newer add_error_table()
977 and remove_error_table() interfaces instead of the much older
978 initialize_*_error_table() function.
980 Add TDB support into the ext2fs library. This allows us to have a
981 guaranteed library we can count on always being present so we can
982 store data in an on-disk database.
984 Add support for using TDB to store the icount data, so we don't run out
985 of memory when checking really large filesystems.
987 Change the regression test suite so that it skips empty test directories.
989 Define the l_i_iversion field in ext2_inode. The l_i_version field is
990 now defined from the old l_i_reserved1 field in the ext2 inode. This
991 field will be used to store high 32 bits of the 64-bit inode version
994 Add Makefile production rule for e2fsprogs.spec in case it gets
997 Add new function profile_get_uint() to allow for a clean way to fetch
998 unsigned integers from the context.
1000 Add test to make sure the ext2 superblock structure is 1024 bytes.
1002 Fix typo in name of f_dup4 regression test
1004 Add new function blkid_gc_cache() which performs a garbage collection
1005 pass on the /etc/blkid.tab file.
1007 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
1008 general, only e2fsck (after the filesystem is clean), tune2fs, and
1009 resize2fs should change the backup superblocks by default. Most
1010 callers of ext2fs_open() should not be touching any superblock fields
1011 which require the backups to be touched.
1013 Add new function to libext2fs, ext2fs_default_journal_size(), which
1014 returns the default journal size.
1017 E2fsprogs 1.39 (May 29, 2006)
1018 =============================
1020 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
1021 between 2**31 and 2**32 blocks.
1023 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
1024 configure the filesystem features, blocksize, and inode_ratio for
1025 different filesystem types.
1027 Mke2fs will now create filesystems hash trees and on-line resizing
1028 enabled by default, based on the new /etc/mke2fs.conf file.
1030 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
1031 filesystem device node in exclusive mode to prevent accidents by
1032 system administrators. In the case of resize2fs and mke2fs, it will
1033 only use exclusive mode if the filesystem is not mounted.
1035 Fixed a bug in mke2fs which caused it to to fail when creating the
1036 resize inode for large filesystems. (Addresses Debian Bug #346580)
1038 When allocating space for the RAID filesystems with the stride
1039 parameter, mke2fs will now place each portion of the group's inode
1040 table right up after the superblock (if present) in order to minimize
1041 fragmentation of the freespace.
1043 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
1044 efficiently by writing the inode and block bitmaps in one pass, thus
1045 reducing the number of disk seeks required.
1047 Add support for on-line resizing to resize2fs.
1049 Fix blkid library so that logic to determine whether or not a device's
1050 cached information in /etc/blkid.tab needs to be verified or not
1051 doesn't get confused by a system clock which is insane (for example,
1052 if the battery is dead on a Macintosh running PPC Linux. (Addresses
1053 Red Hat Bug: #182188)
1055 The blkid library will now store the UUID of the external journal used
1056 by ext3 filesystems, so that in the future, the userspace mount binary
1057 can use this to find the location of the external journal and pass
1058 this information to the kernel.
1060 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
1061 control how various options should be handled. See the e2fsck.conf
1062 man page for more details. (Addresses Debian Bug: #150295)
1064 E2fsck now prints an explanatory message when delaying a filesystem
1065 check when the system is running on battery. (Addresses Debian Bug:
1068 E2fsck will detect if the superblock's last mount field or last write
1069 field is in the future, and offer to fix if so. (Addresses Debian Bug
1070 #327580) These problems will be fixed automatically in preen mode
1071 since Debian's boot sequence bogusly doesn't set the time correctly
1072 until potentially very late in the bootup process, and this can cause
1073 false positives which will cause users' systems to fail to boot.
1074 (Addresses Debian Bugs #343662 and #343645)
1076 E2fsck now checks to see if the superblock hint for the location of
1077 the external journal is incorrect, and if so, offer to update it.

1080 Fix e2fsck from segfaulting on disconnected inodes that contain one or
1081 more extended attributes. (Addresses Debian Bug: #316736, #318463)
1083 E2fsck will stop and print a warning if the user tries running a
1084 read/write badblocks test on a read-only mounted root filesystem.
1086 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
1087 C. Thompson for pointing these out; they were originally found using
1090 When resizing a file containing a filesystem, resize2fs will expand or
1091 truncate a file as necessary. (Addresses Debian Bug: #271607)
1093 Resize2fs will now automatically determine the RAID stride parameter that
1094 had been used to create the filesystem, and use that for newly created
1095 block groups. The RAID stride parameter may also be manually specified
1096 on the command line using the new -S option to resize2fs.
1098 Fix mke2fs so that it correctly creates external journals on
1099 big-endian machines (such as a S/390).
1101 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
1102 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
1103 Chambraud for pointing this out.)
1105 Dumpe2fs will now print the size of the journal (if present).
1107 Fix debugfs's set_inode_field command so it can properly set the frag,
1108 fsize, uid_high, gid_high, and author fields in the inode instead of
1109 silently failing, and so that setting the i_size actually sets i_size
1112 Add a new debugfs command, set_current_time, which sets fs->now so
1113 that regression test suites can repeatedly modify the filesystem's
1116 Fix a bug in debugfs's icheck which would incorrectly report the owner
1117 of an extended attribute block.
1119 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
1120 print a usage message when an illegal option character is given.
1122 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
1123 so it won't core dump. (Addresses SourceForge bug #1424311)
1125 Fix mklost+found so that it creates a full-sized directory on
1126 filesystems with larger block sizes.
1128 Fix a file descriptor leak in blkid library.
1130 Fix a display bug in "badblocks -sv" so that the done message properly
1131 clears the block number at the end of the test. (Addresses Debian Bug
1134 Allow fractional percentages to the -m option in mke2fs and tune2fs

1137 Use fstat/fstat64 in getsize.c if the the target is a regular file,
1138 instead of attempting to do a binary search. Fix some fd leaks in
1141 Add support for device mapper library to the blkid library to ensure
1142 that the "best" (i.e., leaf) device is probed by the blkid library.
1144 Fix the blkid library so that it notices when an ext2 filesystem is
1147 Improve the blkid's library VFAT/FAT detection; it now understands
1148 labels stored in the root directory, and is more paranoid about
1149 checking the FAT superblock values.
1151 Fixed a fd leak in the uuid library which was causing problems for the
1152 LVM tools. (Addresses Debian Bug: #345832)
1154 Add support for the reiser4 and software suspend partitions to the
1155 blkid library. Also add support for extract the label from iso9660
1158 Fix a compile_et bug which miscount the number of error messages if
1159 continuations are used in the .et file.
1161 Add extra sanity checks to protect users from unusual cirucmstances
1162 where /etc/mtab may not be sane, by checking to see if the device is
1163 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug

1192 Fixed the Makefile so that they work correctly on newer versions of
1193 GNU make (i.e., 3.81).
1195 Add valgrind support to the regression test suites, and eliminate
1196 false positives from valgrind.
1198 Add a regression test suite for the blkid library.
1200 Fix a fencepost error in resize2fs caught by valgrind.
1202 Fix compiler warnings about missing memcpy prototypes.
1204 We no longer have the sparc assembly code in the header file any more,
1205 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
1206 break compiles on the sparc architectures when using gcc.
1208 In the libext2fs library, add the new field fs->now which if non-zero
1209 is used instead of the system time when setting various filesystem
1210 fields (last modified time, last write time, etc.)
1212 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
1213 ext2fs.h which is needed since the inline functions use memcpy().
1214 (Addresses Sourceforge Bug #1251062)
1216 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
1217 the build system when building files in the util directory which are
1218 needed during the build process. This avoids potential problems when
1219 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
1220 are not recognized as valid by the host compiler. (Addresses
1221 Sourceforge Bug #1261547)
1223 Clean up the blkid library by making the superblock and generic i/o
1224 functions to be more generic. Clean up interface to the probe
1225 function, and fix memory leak. Finallly, remove an unneeded reference
1226 to probe.h in the lib/blkid/resolve.c
1228 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
1229 of invalid block #'s.
1231 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
1232 indicate that the the function read/writes the memory location.
1234 Fix various gcc -Wall complaints.
1236 Add a dependency to make sure that the subdirectories are created
1237 before creating all of the object files, in order to address parallel
1238 build problem in the library Makefiles. (Addresses Sourceforge Bug:
1241 Add $(LDFLAGS) to the command line argument when generating an ELF or
1242 Solaris shared library, to allow cross-compile and other builds that
1243 might need to specify -L paths to needed libraries. (Addresses
1244 Sourceforge Bug #1261549)
1246 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
1247 intended for testing purposes. It allows an ext2/ext3 developer to
1248 create very large filesystems using sparse files where most of the
1249 block groups are not initialized and so do not require much disk
1250 space. Eventually it could be used as a way of speeding up mke2fs and
1251 e2fsck for large filesystem, but that would be best done by adding an
1252 RO_COMPAT extension to the filesystem to allow the inode table to be
1253 lazily initialized on a per-block basis, instead of being entirely
1254 initialized or entirely unused on a per-blockgroup basis.
1256 Fix backwards compatibility so e2fsprogs will better compile on Linux
1259 Make test scripts more robust against locale-related environment variables
1261 Fix type warning problem with sizeof() in ext2fs_open2().
1263 Fix type warning problem with time_t in debugfs.
1266 E2fsprogs 1.38 (June 30, 2005)
1267 ==============================
1269 Fix blkid's test programs (built with "make check") compile correctly
1270 even without "configure --enable-blkid-debug".
1272 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
1273 type aliasing rules on newer gcc compilers. (Addresses Red Hat
1276 Fix com_err library to make it more compatible with recent changes
1277 made to the com_err library in MIT Kerberos V5 version 1.4.
1278 (Addresses Sourcefroge Bug #1150146)
1280 General cleanup of messages printed by e2fsprogs programs for grammar,
1281 consistency, and to make life easier for translators. Fixed a few
1282 strings containing English that had not been marked as needing
1283 translations. Removed strings that do not need to be translated, to
1284 make life easier for translators.
1286 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
1287 test to see if a device appears to be in use instead of just relying
1288 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
1290 Fix portability problem in the filefrag program affecting platforms
1291 where the size of an integer is smaller than the size of a long.
1292 (Addresses Debian Bug #309655)
1294 Mke2fs will now use a larger journal by default for filesystems
1295 greater than 4GB. (128 MB instead of 32MB).
1297 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
1298 unless forced. This is to avoid signed vs. unsigned kernel bugs in
1299 block numbers that still need to be fixed.
1301 The blkid program has a new option which will more efficiently search
1302 for device when it is known (or expected) that only one matching
1303 device will be found in the system, such as when doing a lookup by
1306 Debian's e2fsprogs-specific initrd fragment will avoid including
1307 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
1308 and LD_LIBRARY_PATH, and filtering out libraries found in
1309 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
1311 Fixed a potential portability issue in the blkid programs for
1312 architectures where the char type is unsigned. (Addresses Sourceforge
1315 Fix a bug in filefrag so that it doesn't falsely count an extra
1316 discontinuity when the first block found is an indirect block.
1317 (Addresses Debian Bug #307607).
1319 Fix blkid's recognition of cramfs filesystems, and enhance it to be
1320 able to handle cramfs labels.
1322 Fix debugfs's stat command to not core dump when a filesystem is not
1325 Fix e2fsck's handling of error conditions caused by the resize inode
1326 claiming blocks that are also used by other inodes, a filesystem
1327 corruption which was commonly caused by a bug in Fedora Core 3's
1330 Fixed bug in filefrag which caused it to fail on non-ext2/3
1331 filesystems. (Addresses Debian Bug: #303509)
1333 If the superblock last mount time indicates that the system clock may
1334 not be accurate, then e2fsck will omit checking inodes' deletion time
1335 field for indications of a potential corrupted orphaned inode list.
1336 (Previously e2fsck only ommited these LOW_DTIME checks when the
1337 superblock's last write time looked insane.)
1339 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
1340 (Addresses Debian bug #302200)
1342 Make the blkid library more paranoid about being run from setgid
1343 programs, and to use __secure_getenv() from libc if it is available.
1345 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1346 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
1347 and Sourceforge Bug: #1189803)
1349 Updated and fixed translations.
1351 Fixed various Debian packaging issues --- see debian/changelog for
1357 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
1358 changed to take an unsigned int for the bit number. Negative bit
1359 numbers were never allowed (and didn't make any sense), so this should
1360 be a safe change. This is needed to allow safe use of block numbers
1361 greater than or equal to 2**31.
1363 The compile_et program will avoid recreating generated foo_err.c and
1364 foo_err.h files if no changes are necessary. The compile_et program
1365 will also atomically replace these files to avoid a potential parallel
1366 build race problem on SMP systems. (Addresses Sourceforge Bug:
1369 Added a new function to the blkid library, blkid_probe_all_new(),
1370 which only probes newly added disk devices, and change
1371 blkid_find_dev_with_tag() to use this function so that when a
1372 requested tag is not found, devices that were previously not checked
1373 are searched before searching all devices in the system.
1375 Added new functions to the blkid library, blkid_dev_set_search() and
1376 blkid_dev_has_tag().
1378 E2fsck's problem strings can now use @m and @n as abbrevations for
1379 "multiply-claimed" and "invalid", respectively.
1381 The e2fsprog.pot file now has an explanation of how the @-expansion
1382 and %-expansion works, and strings in e2fsck/problem.c which contain @
1383 characters now have comments in e2fsprogs.pot with the @-expansion to
1384 make life easier for translators.
1386 Fixed missing return values in the ext2fs library which could cause it
1387 to return random garbage in certain error conditions.
1389 Allow the current time to be overriden via the E2FSCK_TIME environment
1390 variable for use in regression tests.
1392 The test scrpit driver program now exits with a non-zero status if
1393 there any of its test that it ran failed.
1395 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
1398 Fixed "make check" so that it compiles correctly even when e2fsprogs'
1399 header files have not be installed in the system include directories.
1400 (Addresses Sourceforge Bug: #1180572)
1402 Fixed gcc -Wall nits.
1405 E2fsprogs 1.37 (March 21, 2005)
1406 ===============================
1408 Add support for checking the validity of Extended Attributes stored in
1411 Add support for dumping the contents of large inodes to debugfs,
1412 including the extended attributes stored in inodes.
1414 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1415 when we create a new inode we make sure that the extra information in
1416 the inode (any extra fields in a large inode and any ea-in-inode
1417 information) is initialized correctly. This can take place when
1418 mke2fs creates the root and lost+found directory, when e2fsck creates
1419 a new root inode or a new lost+found directory, and when the user uses
1420 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1421 create inode could inherit garbage (or old EA information) from a
1422 previously deleted inode.
1424 Fixed a bug in e2fsck so it would notice if a file with an extended
1425 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1428 Added support to filefrag to detect files which are using the new
1429 experimental file extents format, and use the non-ext2 algorithm in
1430 that case. Fixed a bug to avoid reporting a false discontinuity if
1431 there is one or more unallocated blocks at the beginning of a file.
1433 Duplicated a check for noticing whether or not the number of blocks
1434 (given a certain blocksize) is greater than 2**32 when the
1435 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1436 allows mke2fs to automatically use a larger blocksize when creating a
1437 filesystem on a very large device when run on systems that do not
1438 support BLKGETSIZE64.
1440 Fix the I18N build which was broken in e2fsprogs 1.36 because the
1441 build system had been switched to treat the .gmo files as shipped
1442 files (for backwards compatibility with systems that have older GNU
1443 I18N tools installed), but the gen_tarball.in script was still
1444 removing the .gmo files from the official source distribution.
1446 Fixed various Debian packaging issues --- see debian/changelog for
1447 details. (Addresses Debian Bugs ##296769, #299341)
1452 Added new functions to the e2p library which convert between a string
1453 and os_type: e2p_os2string() and e2p_string2os(), and used them to
1454 make the generated binaries more compact.
1456 Fixed a compile-time error on Darwin systems.
1458 Cleaned up the lib/ext2fs Makefile slightly.
1461 E2fsprogs 1.36 (February 4, 2005)
1462 =================================
1464 All of the patches that were applied to Fedore Core 3's
1465 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1466 lot of bug fixes first. Users of Fedora Core 3 are strongly
1467 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1469 Add support for filesystem with the online resizing via resize inode
1470 feature. Fixed numerous bugs from the Fedora patches. The Fedora
1471 patches also didn't bother to do any consistency checking on the
1472 resize inode, or add any tests to the regression test suite. The "-R
1473 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1474 being listed in mke2fs's usage message. All of these shortcomings
1475 have been corrected.
1477 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1478 program. In order to do this, the user must run the commands:
1480 debugfs -w /dev/hdXXX -R "features ^resize_inode"
1481 e2fsck -f /dev/hdXXX
1483 Optionally, the ext2prepare command can be used to re-enable online
1484 resizing after the filesystem has been fixed.
1486 The fsck program will now accept an optional filedescriptor argument
1487 to the -C option. (The Fedora version of this patch would sometimes
1488 cause fsck to ignore a parameter on fsck's command line in some rare
1491 Make sure e2fsprogs doesn't write garbage into the reserved portion of
1494 Make sure resize2fs releases the blocks belonging to the old inode
1495 table blocks when moving the inode table. (Addresses Debian Bug:
1498 Skip the r_resize_inode test if resize2fs is not compiled (due to
1499 configure --disable-resizer)
1501 E2fsck now checks the summary filesystem accounting information, and
1502 if any of the information is obviously wrong, it will force a full
1503 filesystem check. (Addresses Debian Bug #291571)
1505 Fix e2fsck to not complain when the resize_inode feature is enabled,
1506 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1509 Fix e2fsck to note delete symlinks that contain an extended attribute
1510 after the ext_attr feature flag has been cleared. (Addresses Red Hat
1513 Add new utility program, copy_sparse.c, which is very useful
1514 for dealing with large sparse files (such as e2image files).
1516 Add support for jnl_blocks[] for debugfs's set_super_value.
1518 Fix filefrag so that it works correctly with sparse files.
1520 Filefrag -v will print first and last blocks.
1522 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1525 Add mke2fs support so that it can support filesystems larger than 4TB
1526 automatically, by retrying with a 4k blocksize if the device size is
1527 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1530 Change blkid to test for NTFS first because Windows sometimes doesn't
1531 clear enough of the parition to confuse the probing routines into
1532 thinking the old filesystem type is still valid. (Addresses Debian
1535 Add support for swap partition label and uuid's in the blkid library.
1537 Add support to the blkid library to recognize Oracle ASM volumes.
1539 Make blkid -t display all devices that match the specified criteria,
1540 not just the first one, and work more consistently when the blkid
1541 cache file is not available or set to /dev/null. (Addresses Debian
1542 Bug #290530 and #292425)
1544 Badblocks will now correctly display block numbers greater than
1545 999,999,999 in its progress display.
1547 The tune2fs program will not allow the user from setting a ridiculous
1548 number of reserved blocks which would cause e2fsck to assume the
1549 superblock was corrupt. E2fsck's standards for what is a ridiculous
1550 number of reserved block has also been relaxed to 50% of the blocks in
1553 The blkid library will return vfat in preference to msdos, and ext3 in
1554 preference to ext2 (if the journalling flag is set) so that mount will
1555 do the right thing. (Addresses Debian bug #287455)
1557 Mke2fs will now use the -E option for extended options; the old -R
1558 (raid options) option is still accepted for backwards compatibility.
1559 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1561 Mke2fs will now accept a size in megabytes, gigabytes, and other units
1562 (via "32m" or "4g" on the command line) if the user finds this more
1563 convenient than specifying a block count.
1565 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1566 cache conherency problem.
1568 Debugfs now supports a new command, set_inode_field, which allows a
1569 user to manually set a specific inode field more conveniently, as well
1570 as set entries in the indirect block map.
1572 Debugfs's set_super_value command has been enhanced so that the user
1573 can set most superblock fields, including the date/time fields and
1574 some of the more newsly added superblock fields.
1576 E2fsprogs programs now accept an offset to be passed to the file
1577 specifiers, via the syntax: "/tmp/test.img?offset=1024".
1579 E2fsprogs programs will now accept blocksizes up to 65536; kernel
1580 support on the x86 doesn't exist for now, but it can be useful on
1581 other architectures with page sizes greater than 4k. There are 2.6
1582 kernel patches out there which enable this, but they are of this
1583 writing still experimental.
1585 The e2image command now takes the -s option which will scramble
1586 directory entries for raw image files.
1588 Fix a file descriptor leak in the filefrag program.
1590 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1593 Fix bug in debugfs where kill_file would lead to errors when deleting
1594 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1596 Fix bug in the blkid library when detecting the ocfs1 filesystem
1598 Remove obsolete EVMS 1.x and a.out DLL support.
1600 E2fsck will attempt to recover from a journal containing illegal blocks.
1602 Fixed two potential ordering constraint problems in e2fsck which might
1603 cause the filesystem to be corrupted if e2fsck is interrupted during a
1604 (extremely narrow) race window. Thanks to Junfeng Yang from the
1605 Stanford Metacompilation group for pointing this out.
1607 Fixed bug in e2fsck where it would not accurately detect whether or
1608 not the system is running on adaptor if the ACPI device representing
1609 the AC adapter didn't correspond to the what was used on IBM
1612 Change e2fsck to accept directories greater than 32MB.
1614 Fix e2fsck so that a checkinterval of zero disables a time-based check
1617 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
1618 to the PAGER environment variable. (Addresses Debian Bug #239547)
1620 Tune2fs will not mark rewrite the superblock if the feature bitmasks
1623 The debugfs program will set the filetype information when creating a
1626 Add debugfs -d option to use a separate source of data blocks when
1627 reading from an e2image file.
1629 Add e2image -I option which allows the e2image metadata to be
1630 installed into a filesystem.
1632 Fixed bug in the badblocks program which caused "done" to always
1633 appear in english even when a translation was available. (Addresses
1636 The blkid program has a new option -o which controls the output format
1637 of the blkid program; this is makes blkid more convenient to use in
1640 Fix a minor bug in uuid library, which was not using the full 14 bits
1641 of clock sequence when generating UUID's.
1643 Fix a Y8.8888K problem in the uuid library.
1645 Logsave now creates a new session id for itself to avoid getting
1646 killed by init whan transitioning between init levels.
1648 Change the licensing of the UUID library to be the 3-clause BSD-style
1649 license; this allows Apple to use the uuid library in Darwin.
1651 Add ocfs and ocfs2 probe support into the blkid library.
1653 Fix a memory and file descriptor leak in the blkid library.
1655 The blkid library will revalidate the device if the system time is
1656 earlier than last verification time of the device, since that
1657 indicates that the system time is probably nottrustworthy.
1659 The blkid library will override the default location of the blkid.tab
1660 file by the BLKID_FILE environment variable, if it is available.
1662 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
1664 Add various portability fixes for lame new versions of glibc, Darwin
1665 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
1666 Bugs #239934, #264630, #269044, #255589, #289133)
1668 Add support for Windows 9x/NT under Cygwin.
1670 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
1671 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
1673 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
1675 Update the rpm spec files so that it works better with Fedora core 2
1678 Fixed various Debian packaging issues (see debian/changelog). In
1679 particular, fixed the Debian initrd scripts. (#241183, #248050,
1686 Fixed various gcc -Wall warnings.
1688 The uuid library now has new functions uuid_unparse_upper() and
1689 uuid_unparse_lower() which forces the case of the hex digits to be
1690 upper case, or lower case.
1692 The build process has been speeded up by enhancing the subst program
1693 to update the modtime on the generated files even when the generated
1694 file hasn't changed.
1696 The uuid library now uses C99 stdint.h types instead of custom types.
1698 Updated config.guess and config.sub with newer versions from the FSF.
1700 Removed out of date .cvsignore files from the source distribution.
1702 The ext2fs_unlink() function will return an error if both the name and
1703 inode number are unspecified, to avoid doing something surprising
1704 (such as unconditionally deleting the first directory entry).
1705 Directory entries are now deleted by coalescing them with the previous
1706 directory entry if possible, to avoid directory fragmentation. This
1707 is not an issue with the e2fsprogs suite, but may be a problem for
1708 some of the users of libext2fs, such as e2tools.
1710 Add support for version numbers of the form "1.36-rc1".
1712 Fix build of mke2fs.static.
1714 Add basic ext2fs library support for large (EA in inode) inodes.
1716 The test_io mechanism can now abort after n reads or writes to a
1717 particular block. The block is specified by TEST_IO_BLOCK environment
1718 variable, and the read/write count by the TEST_IO_READ_ABORT and
1719 TEST_IO_WRITE_ABORT environment variables. The block data is now only
1720 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
1722 UUID_DEFINE() in the uuid library now creates a static variable, with
1723 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
1724 be used in header files.
1726 Add support for the install-strip and install-shlibs-strip targets, as
1727 suggested by the GNU coding guielines. "make install" no longer
1728 strips the binaries which are installed.
1730 Remove support for the --enable-old-bitops configure option which was
1731 only for very old sparc systems.
1733 Remove support for --enable-clear-htree; this was only needed during
1734 the early development of the htree patch.
1736 Use Linux-kernel-style makefile output so it is easier to see compiler
1739 Update gettext files to version 0.14.1.
1741 Update to use autoconf 2.5x.
1743 Improved support for compiling e2fsprogs under dietlibc.
1745 Make e2fsprogs portable to Solaris and FreeBSD systems.
1747 Add blkid_verify(), blkid_get_library_version(), and
1748 blkid_parse_version_string() functions to the blkid library.
1750 Add pkg-config files for e2fsprogs's libraries.
1752 Fix "make uninstall" to so that it removes everything that is installed.
1754 Add a configure --enable-maintainer-mode option which enables the
1755 makefile rules to rebuild the configure script from configure.in, and
1756 to reubuild the .gmo files in po directory.
1758 Drop the sparc assembly bitwise operations; it's less efficient
1759 than the GCC 3.4 compile code and triggers compiler warnings on
1760 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
1761 (Addresses Debian Bug #232326)
1764 E2fsprogs 1.35 (February 28, 2004)
1765 ==================================
1767 E2fsck has a new -k option, which in conjunction with the -c options,
1768 preserves the existing badblocks list.
1770 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
1772 E2fsprogs will now deal correctly with symlinks that contain
1773 extended attribute information, which can be created using SE Linux.
1774 (Addresses Debian Bug #232328)
1776 Remove a double longjump into an invalid stack frame bug in e2fsck.
1777 (This was during an abort sequence, which normally worked on Linux and
1778 caused a core dump on other operating systems.)
1780 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
1781 (the NLS library will replace "" with the .po header information).
1783 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
1784 dump due to a division by zero error. (Addresses Debian bug #207082)
1786 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
1787 when reconnecting a directory requires creating a lost+found
1788 directory. (Addresses Debian bug #219640).
1790 Fixed a bug where e2fsck would bomb out if a journal needed to be
1791 replayed when using an alternate superblock.
1793 E2fsck will give an extra grace period before actually forcing a check
1794 if the laptop is running on battery. The next time fsck runs while
1795 the system is on the AC mains, or after the grace period is exceeded,
1796 the filesystem will be checked. (Addresses Debian bug #205177)
1798 E2fsck will inform the user when there are 5 or fewer mounts before a
1799 filesystem check will be forced. (Addresses Debian bug #157194)
1801 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
1802 We now correctly handle the case where there is an overlap between a
1803 block group descriptor or a superblock and a bad block indirect block.
1804 In the case where the indirect block is corrupted, we now suggest
1807 Fix byte swap bugs in e2fsck that caused the journal backup location
1808 in the superblock and symlinks created by SE Linux to be cleared
1809 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
1811 E2fsck -c now replaces the current list of bad blocks with the ones
1814 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
1815 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
1817 Fix a potential bug in e2fsck which could cause it to core dump when
1818 trying to print the location of the backup superblock.
1820 Protect against a potential core dump in e2fsck when printing a
1821 message about backup superblocks.
1823 Add support for backing up the journal inode location in the
1824 superblock. E2fsck will automatically save the journal information in
1825 the superblock if it is not there already, and will use it if the
1826 journal inode appears to be corrupted. ext2fs_add_journal_inode()
1827 will also save the backup information, so that new filesystems created
1828 by mke2fs and filesystems that have journals added via tune2fs will
1829 also have journal location written to the superblock as well.
1830 Debugfs's logdump command has been enhanced so that it can use the
1831 journal information in the superblock.
1833 E2fsck will now update all superblocks when moving the journal inode.
1835 Shrink the size of the e2fsck executable by moving some initialized
1836 variables to the BSS segment.
1838 E2fsck will avoid printing the ^A and ^B characters which bracket the
1839 progress bar when stdout and stdin are a tty device instead of a pipe
1840 to another program. (Addresses Debian bug #204137)
1842 Debugfs's mkdir command will automatically expand the directory if
1843 necessary. (Addresses Debian Bug: #217892)
1845 Fixed a bug in debugfs so that copying a file from /dev/null uses the
1846 correct mode bits. (Addresses Debian Bug: #217456)
1848 If the environment variables DEBUFS_PAGER and PAGER are not set,
1849 debugfs now searches for the appropriate pager to use, beginning with
1850 /usr/bin/pager, and then falling back to 'more' and 'less'.
1851 (Addresses Debian bug #221977)
1853 Debugfs will now support 2.6 device numbers where the major or minor
1854 number may be larger than 255. (Addresses Sourceforge bug #865289)
1856 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
1858 Chattr now stops processing options when it sees '--'. (Addresses
1861 Fix regression tests so they work correctly when e2fsprogs is compiled
1862 with configure --disable-htree.
1864 Fix bug in uuid library when there is no network card and the library
1865 is generating a time-based uuid. The random MAC address was not
1866 correctly generated to be a multicast address.
1868 Add compile_et extensions from Heimdall that were missed the first time
1871 Fix bug in badblocks when using O_DIRECT; we need to make sure that
1872 we're reading from an offset which is page aligned. For read-only and
1873 read-write tests, we try to recover after an error so that we can
1874 continue reading on page-aligned boundaries. (Addresses Debian Bug
1877 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
1880 Updated and clarified various man pages. (Addresses Debian Bug
1881 #206845, #222606, #214920, #232406)
1883 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
1885 Fixed various Debian packaging issues (see debian/changelog).
1890 Fixed a build problem so that e2fsprogs would compile with the
1891 --enable-profile option to configure selected. (Addresses Sourceforge
1894 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
1895 Bugzilla Bug #112448)
1897 Centralize code which calculates the location of the superblock
1898 and block group descriptors so that it is in a single library routine.
1900 Added two new functions, ext2fs_file_open2() and
1901 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
1903 Fix compile_et to output the correct prototype for
1904 initialize_xxx_err_table_r() in the header file. (Addresses Debian
1907 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
1909 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
1910 present. This is for when we try stuffing an int into void * pointer.
1912 Fix type-punning which can cause gcc 3.x to miscompile code by getting
1913 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
1914 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
1915 **'. The EVMS code uses an ugly union approach since we don't want to
1916 modify the EVMS interfaces.
1918 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
1919 aid build process on systems can use invoke GNU make as "gmake".
1921 Added regression testing for mke2fs.
1923 Fixed gcc -Wall nitpicks.
1925 Fixed various compiler warnings.
1927 Add portability fixes for FreeBSD and for using fsctl under Darwin to
1928 support ext2 ioctl's.
1931 E2fsprogs 1.34 (July 25, 2003)
1932 ===============================
1934 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
1935 a tight loop while waiting for a child fsck to exit in some cases.
1936 This burns CPU times which slows down the low-level filesystem check.
1938 Added code to mke2fs to assure that the default block size for a
1939 filesystem is at least as big as the sector size of the device, if it
1942 Changed mke2fs and resize2fs to round the default size of a filesystem
1943 to be an even multiple of the VM pagesize in order to avoid a Linux
1944 kernel bug introduced when the storage of the buffer cache was moved
1945 into the page cache.
1947 Mke2fs will warn the user when creating a filesystem with journaling
1948 and a blocksize greater than 4096. (Addresses Debian bug #193773)
1950 Fixed a bug in resize2fs which caused it to fail on filesystems with a
1951 non-empty bad block list. Resize2fs now discards any blocks on the
1952 badblock list which are no longer part of the filesystem as the result
1953 of a filesystem shrink. (Note: this means that shrinking and then
1954 enlarging a filesystem is no longer a reversible operation;
1955 information about bad blocks in the part of the filesystem which is to
1956 be chopped off will be lost.)
1958 Changed resize2fs so the user can use prefixes to specify the units of
1959 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
1960 and to make the error and informational messages explicitly display
1961 the blocksize used by the filesystem, in order to avoid confusion.
1962 (Addresses Debian bug: #189814)
1964 Added a new debugfs command, dump_unused, which dumps the contents of
1965 all unused blocks to stdout. (Useful as an emergency try-to-find
1966 deleted data command.)
1968 Added a new debugfs command, imap, which prints the location of a
1969 specified inode in the inode table.
1971 Fixed a bug in the badblocks program which caused it to use one bit of
1972 randomness in its non-destructive read/write test, instead of using a
1973 full 8 bits of randomness.
1975 Added a new option (-t) to badblocks, which allows the user to control
1976 the test pattern(s) used when checking a disk.
1978 The blkid probe function now more correctly detects UDF filesystems.
1980 Fixed a bug in the blkid library which caused it to not update its
1981 cache if a filesystem changes from having a label to not having a
1984 Fixed a bug in the blkid library wihch could avoid an infinite loop
1985 in blkid_find_dev_with_tag() if /proc is not mounted and there the
1986 /etc/blkid.tab file has not yet been created.
1988 Fixed the badblocks program so that the destructive read/write test
1989 honors the -c option, and to use O_DIRECT when possible to avoid
1990 thrashing the system block buffer cache.
1992 Fixed various NLS issues.
1993 - Added Czech and Swedish translations
1994 - Removed testing NYC translation
1995 - Fixed NLS support for message abbrevations in e2fsck
1996 - Remove de-utf.po, since we shouldn't have two versions using different
1998 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
1999 simplify the statistics reporting in e2fsck.
2001 Changed configure.in so that its defaults for *BSD systems no longer
2002 build an fsck wrapper, and not to install in /usr/local by default.
2004 Fixed some minor spelling errors/typo's in e2fsck and the configure
2007 Fixed various Debian packaging issues (see debian/changelog).
2009 Updated and clarified man pages. (Addresses Debian Bug #195616)
2014 Fix gcc -Wall nitpicks.
2016 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
2017 NLS support by default. (Added partial workaround for gettext/Darwin
2018 incompatibility problems.)
2020 Added full MIT KRB5 and Himdall compaibility support to the com_err
2021 library and the compile_et program. (Addresses Debian bug #191900)
2023 Added the blkid_known_fstype() function to the blkid library, which
2024 returns true if it is passed a filesystem type which is recognized by
2025 the blkid probing functions.
2027 Improved the documentation for the blkid library.
2029 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
2030 returns the hardware sector size of a device, if it is available.
2032 Added a dependency in the blkid library's .so file to the uuid
2033 library, since the former uses the latter. (Addresses Debian bug
2036 Added --with-diet-libc and --disable-evms to the configure script.
2038 Fixed a minor memory leak in the badblocks program.
2040 Fixed a portability problem in tune2fs --- not all systems have strptime().
2042 Fixed a portability problem in debugfs with the use of getopt() more
2043 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
2046 Add support Windows support to ext2fs_get_device_size().
2048 Added (normally disabled) debugging code to the Unix I/O manager which
2049 causes it to disable all userspace caching if the NO_IO_CACHE is
2052 Changed the test I/O manager so it can always be linked into e2fsck,
2053 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
2054 configure script. The test I/O manager will only print any debugging
2055 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
2056 variables are set, which specifies which I/O operations are logged and
2057 a block number to watch, respectively. The log messages are sent to
2058 stderr by default, unless a filename is specified via the
2059 TEST_IO_LOGFILE environment variable.
2062 E2fsprogs 1.33 (April 21, 2003)
2063 ===============================
2065 Added a new utility program, logsave, which captures the output of a
2066 command in a log file, even if the containing directory hasn't been
2067 mounted yet (in which case the it saves the output in memory until it
2068 can write out the logfile). This is useful for capturing the
2069 output of fsck during the boot sequence.
2071 Fixed some portability problems that were causing problems under
2072 the Cygwin32 environment.
2074 Mke2fs now interprets a negative number to the -b option as a minimum
2077 Fixed a bug in mke2fs which was incorrectly checking the argument to
2078 the -g option if the default block size was used. (Addresses Debian
2081 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
2082 it can not find filesystem checkers for jfs, reseirfs, and xfs.
2084 E2fsck now updates the global free block and inode counters from the
2085 block group specific counters quietly. This is needed for an
2086 experimental patch which eliminates locking the entire filesystem when
2087 allocating blocks or inodes; if the filesystem is not unmounted
2088 cleanly, the global counts may not be accurate.
2090 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
2091 2.0 is not yet supported; this only pulled in the bug fixes: fixed
2092 possible hangs caused by bugs in calling waitpid, and not setting the
2093 pipe to non-blocking mode; also fixed a file descriptor leak; made
2094 sure all functions call log entry/exit functions.)
2096 Badblocks now flushes its output file as bad blocks are discovered.
2098 The uuid library is now more paranoid about assuming the correctness
2099 of the /dev/random device; it mixes in a stream of bytes from
2100 random/srandom, just in case.
2102 Update Debian files to reflect the fact that I am now the Debian
2103 maintainer of e2fsprogs. Other various Debian-specific packaging
2106 Move the source tarball generation functions from the top-level
2107 makefile to the util/gen-tarball script.
2109 Updated the Turkish .po translation file.
2111 Added Heimdal and MIT krb5 extensions to the com_err library to make
2112 it more compatible with com_err libraries from those distributions.
2114 Changed dumpe2fs to always display the superblock fields relating to
2115 the journalling and/or directory indexing feature even if those
2116 features are not enabled.
2118 Updated and clarify copyright statement vis-a-vis alpha releases of
2121 The ss library will now try to dynamically link to the readline
2122 library and use it if it is present in the system. This means that
2123 the debugfs program now has line editing and history features. The
2124 SS_READLINE_PATH environment variable is used to find a readline or
2125 readline-compatible library.
2127 E2fsck now finds most duplicate filenames (all when rebuilding all
2128 directories via the -D option) and offers to delete or rename
2129 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
2131 Fix bug in e2image. When writing out a raw image file, include data
2132 blocks from symlinks that do not store the symlink within the inode.
2134 Fix bug in resize2fs which incorrectly moved the block and inode
2135 bitmaps for sparse superblock filesystems and incorrectly marked
2136 blocks as in use. (Addresses Debian bug #174766)
2138 Added a new shared library, the blkid library, which efficiently
2139 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
2140 and UUID filesystem specifiers without needing to search all of the
2141 devices in the system. Instead, the device is looked up in a cache
2142 file, and then verified to make sure the blkid cache is correct.
2144 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
2145 the device name, using the blkid library. (Addresses Debian bugs
2148 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
2149 used for spaces in device labels.
2151 Removed 32-bit limitations for debugfs's dump command.
2153 If the user specifies a large number of inodes, Mke2fs will
2154 automatically adjust the number of blocks per group to find a valid
2155 set of filesystem parameters.
2157 Add workaround to detect broken MD devices where when some of the
2158 underlying devices are marked read-only, writes to the MD device are
2159 silently dropped. E2fsck will detect if there is an attempt to run
2160 the journal twice, and abort with an error if this is the case.
2161 (Addresses IBM Bugzilla bug #1226)
2163 E2fsck will print an error if more than one of the -p/-a, -n or -y
2164 options are specified.
2166 E2fsck will fix HTREE corruptions in preen mode, without stopping the
2167 boot process. This is needed because the 2.4 ext2 filesystem
2168 accidentally had the INDEX_FL backwards compatibility code removed.
2170 Mke2fs no longer creates filesystems with the dir_index flag set by
2171 default; the user has to specifically request it.
2173 Update and clarified various man pages. (Addresses Debian bugs
2174 #173612, #175233, #175113, and #170497, #185945, #188318)
2176 Created man page for the mk_cmds program (from the libss library).
2181 Fix various gcc -Wall nits.
2183 Fixed a lot of portability problems that caused e2fsprogs not to build
2184 successfully under Solaris and Apple/Darwin.
2186 Fixed a Makefile dependency to allow building e2fsprogs using parallel
2189 Changes to create a subset distribution which consists only of the
2190 et, ss, uuid, and blkid libraries. The configure script and top-level
2191 makefile were changed to support working with a subset distribution.
2193 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
2194 actually used, and might people who are looking for
2195 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
2197 Updated debian files to fix a number of Lintian warnings.
2199 Updated config.guess and config.sub with newer versions from the FSF.
2201 Removed unnecessary libraries from being linked into the fsck, lsattr,
2202 chattr, and blkid executables.
2204 E2fsprogs 1.32 (Nomvember 9, 2002)
2205 ==================================
2207 Fixed a bug in the Unix I/O routines which caused needless writebacks
2208 of clean blocks from the unix_io cache (they were erroneously marked
2209 as being dirty, so they were getting written back to disk before
2210 getting evicted from the disk cache). This was harmless, but it
2211 significantly slowed down e2fsck.
2213 Made some other minor optimizations to the Unix I/O routines to save a
2214 small amount of CPU time.
2216 Updated internationalization files.
2219 E2fsprogs 1.31 (Nomvember 8, 2002)
2220 ==================================
2222 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
2223 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
2224 handling for child process that die unexpectly. Add a hack to force
2225 mkfs to create filesystems that won't cause problems with hardware
2226 that has 2k or 4k minimum blocksize requirements. Read from child
2227 processes in non-blocking mode, so that the GUI continues to update.
2229 Fix e2fsck so that it returns the appropriate exit code when the root
2230 filesystem has been changed, so that system's rc scripts will be told that
2231 the system needs to be rebooted.
2233 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
2234 was set, some of the descriptor blocks that should have been written
2235 out were getting skipped.
2237 Changed e2fsck to force out changes to the backup copies of the
2238 superblock and block group descriptors when important changes are made
2239 to those data structures.
2241 Fix a bug where e2fsck could erroneously mark a filesystem as being
2242 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
2243 introduced in e2fsprogs 1.28.)
2245 If journal debuging is enabled using --enable-jbd-debug, the debugging
2246 level is now set via the E2FSCK_JBD_DEBUG environment variable.
2248 If byteswapping support is disabled using configure --disable-swapfs,
2249 skip the tests which depend on byte-swapping, so that "make check"
2252 Lshattr will now display the indexed directory flag. Also, some of
2253 the more esoteric compression flags are supressed unless compression
2254 support has been enabled.
2259 E2fsprogs 1.30 (October 31, 2002)
2260 =================================
2262 When resizing a filesystem, and inodes need to moved, resize2fs will
2263 update the inode's ctime field, and the mtime field of the containing
2264 directories, so that incremental backups using dump/restore will work
2267 In order to avoid spurious errors, e2fsck wil check the last
2268 superblock write time to determine whether or not it can safely use
2269 the LOW_DTIME checks to determine if there are inodes on the orphan
2270 inode linked list that had somehow gotten disconnected. (Addresses
2271 Sourceforge bug #620980)
2273 Partition in /proc/partitions that being with the string "lvm" are
2274 considered real partitions even if they do not end with a number.
2276 Fixed a bug in the the uuid generation function, where if /dev/urandom
2277 is not present, but /dev/random is, and there isn't sufficient
2278 entropy, the get_random_byte function could spin a loop forever.
2280 E2fsck, mke2fs, etc. will now reliably notice when image files are
2281 mounted using the loopback interface. (Addresses Sourceforge bug
2284 When flushing buffers (as is done by badblocks, for example) check to
2285 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
2286 FDFLUSH ioctl which causes the MD device driver which causes confusing
2287 syslog messages about obselete ioctl messages. (Addresses Sourceforge
2290 Debugfs's write command now checks to see if the destination filename
2291 exists before creating it. (Addresses Sourceforge bug #478195.)
2293 When installing man pages, search for compressed man pages using all
2294 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
2296 Fixed a bug in fsck where multiple filesystems specified on the
2297 command were not being checked in parallel due to a logic bug
2298 introduced to support the FSCK_MAX_INST environment variable.
2300 We have added a new superblock field, s_mkfs_time, which indicates
2301 when a filesystem was created. It is set via mke2fs, and printed out
2302 by dumpe2fs, but is not actually touched by the kernel.
2304 Dumpe2fs has been made more robust by not aborting if there is an
2305 error reading the block/inode bitmaps; instead it will still print out
2306 the location of the block/inode bitmaps and inode table.
2308 Add support for the an alternative block group descriptor layout which
2309 allows for on-line resizing without needing to prepare the filesystem
2310 in advance. (This is the incomat feature flag meta_bg.)
2312 Add support for storing default mount options in the superblock, so
2313 that the filesystem can be mounted with specific mount options without
2314 needing to specify them on the mount command line or in the /etc/fstab
2317 Add support for a new inode flag, which is to be used for indicating
2318 the top of directory hierarchies for the Orlov block allocator.
2320 Fix e2fsck so that if it creates the lost+found directory, it does so
2321 with the more apporpriate permissions of 0700. Also change
2322 mklost+found so that it also creates the directory 0700.
2324 Fixed format bug in e2fsck if NLS is in use.
2326 Add a German translation for e2fsprogs's NLS support.
2328 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
2329 the beginning of the inode table. This won't matter much, since if
2330 there is a bad block at the beginning of the inode table, the root
2331 directory won't be available. But at least e2fsck won't crash in this
2334 Fixed endian problems in the htree code for e2fsck and debugfs.
2336 When byte-swapping a filesystem on a PPC architecture, byte-swap the
2337 bitmaps since the historical big-endian ext2 variant had byte-swapped
2338 bitmaps, and the ext2fs library assumes this. This fixes the
2339 regression test suite on PPC machines.
2341 Fix e2image so that it handles a bad block in the inode table
2344 E2fsck now uses a more sophisticated algorithm to salvage corrupted
2345 directories that recovers more information in the corrupted directory
2348 E2fsck now performs additional consistency checks on indexed (HTREE)
2351 Fix bug where efsck might get confused about whether a completely
2352 empty directory block is an empty leaf block or an interior htree
2353 node. This could cause e2fsck to get confused into think that a valid
2354 indexed directory was corrupted.
2356 E2fsck no longer creates an empty directory entry at the end of a
2357 directory block when optimizing a directory. This would cause some
2358 earlier versions of the dxdir kernel code to corrupt the directory
2359 when attempting to split a node containing an empty directory entry.
2361 E2fsck could sometimes in rare circumstances leave the indexed flag
2362 set after a small directory was optimized by compressing it instead of
2363 indexing it. (This should never happen in real life, since
2364 directories that small wouldn't have been indexed, but better safe
2367 E2fsck now only updates the master superblock in all cases. This
2368 slightly shortens its run time.
2370 Ext2ed can deal with directory entries of length 0; previously it
2371 would get stuck in an infinite loop.
2373 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
2374 specifiers. (Sourceforge patch #613447)
2376 Badblocks will now work correctly on read-only devices such as
2377 CD-ROM's. (Sourceforge patch #600451)
2379 Updated and clarified man pages. (Addresses Debian bug #167108)
2382 E2fsprogs 1.29 (September 24, 2002)
2383 ===================================
2385 Fixed a bug in e2fsck which could corrupt a directory when optimizing
2386 it (via the -D option) or rebuiliding the hash tree index with a 1 in
2387 512 probability, due to a fence post error.
2389 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
2392 Mke2fs now enables the directory indexing flag by default. (Since
2393 this is a compatible feature flag, it's safe to do so.)
2395 Tune2fs will support setting the directory indexing feature flag. It
2396 will automatically set up the default hash algorithm and hash seed
2397 fields in the superblock.
2399 If the bone-headed user enters the root filesystem twice in
2400 /etc/fstab, the -R option which skips the root filesystem will skip
2401 all of them. (Addresses Debian bug #159423). Note! This is not a
2402 precedent for dealing intelligently with any other kind of doubled
2403 entry in /etc/fstab!
2409 Removed perror declaration in lib/et/internal.h. All modern systems
2410 can be expected to define perror() these days. Besides, the lib/et
2411 code wasn't using perror at all anyway. :-)
2414 E2fsprogs 1.28 (August 31, 2002)
2415 ================================
2417 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2418 for setting the htree flag is not included yet, although it can be
2419 manually turned on via the debugfs program.
2421 Clarified e2fsck error message which is printed when it cannot find
2422 sufficient contiguous block when relcating filesystem metadata.
2424 Added support for building an EVMS plugin module for ext2/3. This
2425 module is substantially the same as the EVMS module shipping with EVMS
2426 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
2427 for use with EVMS 1.0 (which did not include the ext2 plugin module),
2428 if the configure --enable-old-evms flag is given.
2430 Fsck will search through EVMS volumes when trying to resolve
2431 filesystem specifications such as LABEL=xxx or UUID=xxx.
2433 Added a new utility program, /sbin/findfs, which will return
2434 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2437 Update and clarified various man pages. (addresses Debian Bug #145044,
2438 #146437, #131350, #151990, #144621, #141938)
2440 If there are no filesystems specified on fsck's command line, fsck now
2441 treat that as if the -As options were given. Previously it would
2442 simply do nothing. (Addresses Debian Bug #153102)
2444 Mke2fs no longer treats a failure to be able to clear the MD signature
2445 at the end of the filesystem as a fatal error. (Addresses Debian Bug
2448 The e2p library functions (which are used by lsattr and chattr) now
2449 double check to make sure the file is a regular file or directory
2450 before attempting to use the ext2 ioctls. Some device drivers
2451 unfortunately respond to the ext2 ioctl's with unknown behaviour.
2452 (Addresses Debian Bug #152029).
2454 The extended attribute handling has been updated to correspond with
2455 the latest V2 bestbits ACL code.
2457 Fixed bug in e2fsck which caused it to not clear the dtime field when
2458 processing truncated inodes on the orphan list. This could cause data
2459 loss(!) if a filesystem is rebooted before a truncate has been
2462 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2463 algorithms. This makes e2fsck much faster in the case of severely
2464 corrupted filesystems where a large number of blocks are claimed by a
2465 large number of inodes. (Thanks to the 2.5 IDE device driver for
2466 inspiring this work.)
2468 Resize2fs has been significantly sped up when shrinking and expanding
2469 a filesystem by a very small number of blocks (for example, when EVMS
2470 is converting a partition to be an EVMS legacy volume).
2472 Added a new option to e2fsck, -D, which will optimize or compress all
2473 of the directories in the filesystem.
2475 E2fsck now catches SIGINT and SIGTERM to make sure it will can
2476 properly clean up and only exit at safe points. Fsck will pass
2477 SIGINT/SIGTERM to its child processes, and wait until they have all
2478 exited before it exits.
2480 The uuid parsing code in the uuid library now properly complains when
2481 an illegally formated uuid is presented to it. (Addresses Debian bug
2484 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2485 and 2.4.17, since the workaround can cause problems when using a 2.4
2486 kernel with an old version of glibc built with the 2.2 headers.
2488 Fixed a bug in mke2fs where it wasn't properly clearing the initial
2489 superblock used by other filesystems. (Addresses Debian bug #147256.)
2491 Added support for the synchronous directory feature written by Andrew
2494 The debugfs program can delete directories using the rmdir command.
2496 Add support for 8k and 16k filesystems (for systems with page sizes
2497 that are greater or equal to 8k or 16k, respectively). Note that
2498 these filesystems can not be mounted on x86 systems, or other systems
2499 with only 4k page sizes, due to limitations in the current Linux VM
2502 Resize2fs requires that the filesystem state be valid and have no
2503 errors; otherwise, e2fsck -f must be run first. (Previously it simply
2504 required that the last fsck time be greater than the last mount time.)
2506 Configure now defaults the man pages directory to /usr/share/man on
2509 E2fsck now offers to truncate inodes which contain too many blocks (so
2510 that i_blocks would overflow. Also fixed handling of large sparse
2513 E2fsck now more completely checks for symlink validity, including
2514 requiring NULL termination and length checks.
2516 E2fsck will offer to try forcing a disk write to remap a bad block
2517 after finding a read error when reading a filesystem metadata block.
2519 Fixed a bug in debugfs which caused the -b and -s options to crash
2520 debugfs, as well as breaking the testb, setb, and clearb functions.
2522 Added a bmap command to debugfs which calculates the logical to
2523 physical block mapping for a particular inode.
2525 Fixed a bug in code which checked to see if a device was mounted which
2526 sometimes (rarely) failed in the case of a plain file.
2528 Fixed a bug in resize2fs where when it reported an error, it would
2529 print a message erroneously indicating that the filesystem had been
2530 resized before it aborted.
2532 When resizing a plain file which is smaller than the requested size,
2533 resize2fs will attempt to extended the file so that programs like
2534 e2fsck will not complain that the file is too small.
2536 Resize2fs will print the actual new size of the filesystem when it is
2539 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2540 information on big-endian systems.
2546 Fixed collisions with C++ reserved words.
2548 Added portability fixes for building e2fsprogs on the HURD and AIX.
2550 Added the ext2ed program for creation of test cases. (ext2ed has many
2551 limitations and bugs which make it unsuitable for production use.)
2553 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2554 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2555 name_len field is byte swampped on big-endian machines, since in the
2556 V2 structure, name_len is a char field which is doesn't need to be
2557 byte swapped --- except if an old-style kernel had byte-swapped the
2558 name_len field as part of the V1 structure.
2561 E2fsprogs 1.27 (March 8, 2002)
2562 ==============================
2564 The warning messages for mke2fs now go to standard error.
2566 Fixed to make sure "make check" runs all of the test programs with
2567 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2569 The mke2fs program checks the boot sector for the BSD disk label, and
2570 avoids erasing it if it is there.
2572 Fixed a bug in e2fsck which caused it to core dump if the journal
2573 inode was missing when it was supposed to be there.
2575 E2fsck now prints ranges in pass 5 when printing deltas for the block
2578 Debugfs's "ls -l" command now will print out the file type information
2579 in the directory entry.
2581 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2582 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2584 Debugfs can now examine the experimental directory indexing
2587 Fixed bug in debugfs which caused it to core dump if modify_inode is
2588 called without an open filesystem.
2590 The debugfs lsdel command now runs its output through a pager first.
2592 When installing manual pages, remove the compressed manual pages first.
2594 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2596 Fix the 2.4 resource limitation workaround introduced in 1.26 which
2597 actually broke things on mips32, sparc32, and Alpha platforms.
2599 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2600 (which is required by the newer libintl libraries).
2605 Fixed various gcc -Wall complaints.
2607 Fixed a few memory leaks in the e2fsck journaling code, and in the
2608 ismounted code checking for a swap device.
2610 Add new inode I/O abstraction interface which exports an inode as
2613 Exported ext2_file_flush as a public interface.
2615 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
2617 Lots of small random portability fixes to make e2fsprogs build under
2618 AIX --- even without the 5L compatibility toolkit, and even using the
2619 uber-crippled AIX native C compiler.
2622 E2fsprogs 1.26 (February 3, 2002)
2623 =================================
2625 Dumpe2fs will keep going now if the bad block inode can't be read.
2626 (Previously it stopped with a fatal error.)
2628 E2fsck will now give an opportunity to run the journal even if the
2629 recovery flag is not set. This is the default behaviour if e2fsck is
2630 using a backup superblock, since the needs_recovery flag will never be
2631 set in the backup superblock copies.
2633 E2fsck now automatically finds the backup superblock/group descriptors
2634 even when the primary superblock is completely destroyed for 2k and 4k
2635 filesystems. (Previously it just guessed/assumed that we were dealing
2636 with a 1k filesystem in that case, and users had to manually specify
2637 the backup superblock number.)
2639 Fixed a bug in e2fsck where it dereferences a null pointer when there
2640 is a problem opening a filesystem in preen mode.
2642 E2fsck now handles external journals correctly; previously it trashed
2643 the external journal device if the journal needed to be replayed.
2645 Work around ulimit incompatibility problem caused by recent 2.4
2646 kernels; the unix IO module will automatically try to set any resource
2647 limits to be infinite on startup.
2649 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
2650 bitmap if it wasn't present and the blocksize was 2k or 4k.
2651 (Addresses Debian Bug #116975)
2653 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
2654 clearing the new V2 fields if they do not make sense or if the ext3
2655 superblock is version 1 superblock.
2657 E2fsck will automatically relocate the ext3 journal from a visible
2658 file (i.e., /.journal) to an hidden inode if the filesystem has been
2659 opened read/write. This allows the users to add a journal while the
2660 filesystem is mounted, but the next time the system is rebooted, the
2661 journal file will disappear. This avoids problems with backups,
2662 stupid operators with superuser bits, etc.
2664 Fix a bug in fsck where it would not support a filesystem type of
2665 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
2667 Fsck now supports fstab entries of the form "ext3,ext2". It will also
2668 automatically identify reiserfs filesystems.
2670 The number of processes spawned by fsck can now be limited using the
2671 FSCK_MAX_INST environment variable.
2673 Fsck now searchs the LVM proc hierarchy to find logical volumes which
2674 should be searched for UUID and label information.
2676 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
2677 limit if at all possible, when opening a block device. (The filesize
2678 limit shouldn't be applied against writes to a block device.)
2680 In mke2fs and e2fsck, specifying the -c option twice will now do
2681 a read/write test on the disk. Update the man pages to encourage
2682 using the -c option, and to discouraging running badblocks separately,
2683 since users tend to forget to set the blocksize when running
2686 Mke2fs now automatically clears the immutable attribute on a
2687 pre-existing .journal file left over from a previous failed attempt to
2688 add a journal to an alreadyy-mounted filesystem.
2690 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
2693 Mke2fs now creates the lost+found directory with permissions of 0700,
2694 so that files that had previously lived in protected directory are
2695 safe if they get dropped in lost+found and the system administrator
2696 doesn't deal with immediately. (Addresses Debian #bug 118443)
2698 Mke2fs and e2fsck (and all programs that use the
2699 ext2fs_check_if_mounted function) will now properly identify that a
2700 device is mounted, even in cases where devfs has confused things with
2701 multiple devices names with the same identity, or if a dim-witted
2702 system administrator has done something stupid like creating device
2703 file aliases in their home directory. Also now checks for swap devices
2704 by using /proc/swaps. (Addresses Debian bug #106622)
2706 Added a new option (-T) to tune2fs which sets the time a filesystem
2709 Speed up e2image when creating sparse raw image files by optimizing
2710 away excess lseek() system calls.
2712 Fix support of large (> 2GB) files when used as a filesystem in
2713 mke2fs, tune2fs, debugfs, and findsuper.
2715 Debugfs's stat and icheck commands now properly deals with large (>
2718 Debugfs's set_super_value command now prints out the list of valid
2719 superblock fields which can be set using the command.
2721 Debugfs's rm and kill_file command now updates the superblock free block
2722 and inode counts, thus keeping the filesystem consistent.
2724 Debugfs's lsdel command now takes an optional argument which allows
2725 the user to only see the most recently deleted files.
2727 A new command (undel) was added to debugfs which automates
2728 undeleting a deleted inode and linking it back to a directory.
2730 Debugfs's ls command now takes a new option, -d, which lists
2731 deleted directory entries.
2733 Debugfs's testb, freeb, setb, and find_free_block commands now take an
2734 optional count argument.
2736 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
2737 be used to signal that a particular inode should not be eligible for
2738 tail-merging --- this is needed for programs like LILO.
2740 The findsuper (an unreleased, uninstalled utility program) has been
2741 improved to add extra validity checks and to add a progress meter.
2742 (It is still an unsupported program; the officially supported way to
2743 recover from a trashed partition table is to use gpart; findsuper is
2744 for wizards only. :-)
2746 Debugfs was fixed to compile with "configure --disable-swapfs".
2748 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
2750 Added new translation file for Turkish.
2755 Fix general gcc -Wall complaints.
2757 E2fsprogs (mostly) works with the dietlibc.
2759 The programming texinfo file has been expanded to include description
2760 of additional libext2fs functions. (Still not compeltely done, but a
2761 lot of the more important functions have been documented.)
2763 Added a umask structure to struct_ext2_filsys, which currently only
2764 modifies the behaviour of ext2fs_mkdir(), but if we add any file
2765 creation functions to libext2fs, we should also make sure they respect
2768 The build-rpm script was fixed to be a bit more safe.
2770 The tests' Makefile now has a way of automating test case creation
2771 for e2fsck, using "make testnew".
2773 Created a new function, ext2fs_dir_iterate2 which passes more
2774 information to the callback function (identical to the one used by
2775 ext2fs_dblist_dir_iterate). The directory iterator functions take a
2776 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
2777 directory entries. If the directory entry is deleted, the callback
2778 function will be called with the entry paraemter set to
2779 DIRENT_DELETED_FILE.
2781 Added new functions, ext2fs_inode_alloc_stats and
2782 ext2fs_block_alloc_stats, which takes updates block/inode allocation
2783 statistics in the bitmaps, block group descriptors, and superblock
2784 when inodes or blocks are allocated or deallocated.
2787 E2fsprogs 1.25 (September 20, 2001)
2788 ===================================
2790 This is primarily a bug-fix release; no new features were added, but
2791 there are a number of embarassing bug fixes and cleanups applied.
2793 Fix a bug mke2fs which causes stack garbage to be written to disk when
2794 zapping disk sectors. (This bug could cause mke2fs to core dump for
2795 some kernels, I suspect with security enhancement patches.)
2797 Remove unneeded #include of <linux/config.h> which was breaking
2798 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
2800 Updated tune2fs man page to reflect the fact that adding or removing a
2801 journal doesn't require running e2fsck.
2803 Remove use of AC_REQUIRE from autoconf which had been used to prevent
2804 AC_CANONICAL_HOST from being called twice; unfortunately this causes
2805 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
2806 used outside of autoconf macros. Fortunately, it doesn't seem to be
2807 necessary any more, anyway.
2809 E2fsck will now not fall back to an alternate superblock if the user
2810 specifies the superblock location explicitly on the command-line.
2811 This allows easier recovery from a situation where the primary
2812 superblock and block groups are slightly corrupted, but the backup
2813 superblocks are completely broken.
2815 Fix problem which caused compile_et and mk_cmds to blow up if
2816 e2fsprogs was in a directory with a pathname that contained spaces.
2818 We are now more paranoid about checking the entry in /etc/mtab to make
2819 sure the filesystem is really mounted, since some broken distributions
2820 (read: Slackware) don't initialize /etc/mtab before checking non-root
2821 filesystems. (Slackware also doesn't check the root filesystem
2822 separately, and reboot if the root filesystem had changes applied to
2823 it, which is dangerous and broken, but there's nothing I can do about
2826 Make UUID library C++ friendly by adding appropriate extern "C"
2827 declarations and using const in the function declarations.
2829 Fix up the com_err texinfo file so that it can product a valid info
2830 file (previously, it could only be used to generate paper
2831 documentation using texinfo.tex).
2834 E2fsprogs 1.24a (September 2, 2001)
2835 ===================================
2837 Fix brown-paper bug in mke2fs which caused it to segfault when
2838 printing the version string.
2841 E2fsprogs 1.24 (August 30, 2001)
2842 ================================
2844 Revert the BLKGETSIZE64 support, since for some distributions, this
2845 ioctl has been used by an unofficial kernel patch to update the last
2846 sector on the disk, and this was causing disk corruption problems as a
2849 Mke2fs is now more careful about zapping swap space signatures and
2850 other filesystem/raid superblock magic values so that programs like
2851 mount who try to use hueristics to determine the filesystem type of a
2852 partition are less likely to be confused.
2854 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
2855 regular file (since Andreas Dilger's on-line resizing tools will set
2858 Fixed some minor texinfo, man pages nits for spelling errors,
2859 texinfo warnings, etc. (Addresses Debian bug #110621.)
2861 E2fsprogs program no longer print the filesystem version number
2862 (i.e. 0.5b), since it only confuses people and doesn't serve any real
2865 E2fsck will once again compile under libc5, since it will supply its
2866 own version of strnlen if necesssary.
2868 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
2869 when specifying the external journal device. tune2fs will also search
2870 devices looking for the externla journal debice when removing.
2872 E2fsprogs 1.23 (August 15, 2001)
2873 ================================
2875 Add initial support for extended attributes (EA); e2fsck will
2876 correctly handle a filesystem with EA's and check the EA blocks for
2879 E2fsck's symlink sanity checking has been cleaned up. It now checks
2880 the i_size value of fast symlinks, and checks for immutable flags
2881 being set of symlinks, etc.
2883 E2fsck now offers to clear inodes which are special files that have a
2884 non-zero i_blocks or i_size field. (The i_size field check was in the
2885 previous version of the code, but due to a bug it didn't offer to
2886 clear the inode unless i_size and i_size_high were both non-zero.)
2888 E2image can now create "raw" image files, which only contain the
2889 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
2890 debugfs, etc., can be run directly on the raw image file.
2892 Add support for the 64-bit block device patches.
2894 Fixed bugs in creating external journals with a 1k blocksize.
2896 Add initial support for external journals (so long as the external
2897 journal only supports a single filesystem) in e2fsck.
2899 Remove requirement for needing to run fsck on a filesystem after
2900 removing a journal (either internal or external).
2902 The man pages now document how to create and manage external journals.
2904 Speed up the check of an ext3 filesystems by avoiding a needless flush
2905 of all of the superblock and block group descriptors.
2907 Speed up creating an internal journal using tune2fs in the case where
2908 the filesystem has a lot blocks already allocated.
2910 Tune2fs has been fixed to make sure that only error messages go to
2911 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
2913 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
2914 now not set the sparse_super feature. (Addresses Debian bug #108165)
2916 Add support in fsck for the filesystem type "auto".
2918 Fsck -A will not try to interpret device names for filesystems which
2919 have a pass number is 0. (Addresses Debian bug #106696).
2921 Fsck prints a warning message if now valid filesystems are passed to
2922 it. (Addresses Debian Bug #107458.)
2924 E2fsck now gives an explicit warning if there filesystem still has
2925 errors at the end of the run. (Addresses Debian bug #104502)
2927 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
2928 reflects an error. E2fsck will also not run the orphan list if the
2929 filesystem contains errors, since the orphan list might be corrupted.
2931 E2fsck now prints the number of large files when given the -v option.
2933 Fixed minor memory leaks in e2fsck.
2935 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
2938 E2fsprogs 1.22 (June 22, 2001)
2939 ==============================
2941 Fixed a bug in e2fsck's handling of orphan inodes which are special
2942 files (i.e., block/character device files, named FIFO's, etc.).
2944 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
2945 tune2fs to fail at adding a journal to a mounted filesystem.
2947 Fixed a few big-endian bugs in e2fsprogs
2948 * The directory block functions were accidentally reporting
2949 some directories as corrupted when they weren't.
2950 * If e2fsprogs is compiled --disable-swapfs, the C language
2951 equivalents weren't being included for big-endian platforms.
2952 (Fixes Debian bug #101686).
2954 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
2959 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
2960 ioctls, and allow them to be defined for non-i386 platforms.
2962 The uuid.h header file is now protected against multiple inclusions.
2964 E2fsprogs is now being developed using BitKeeper. Changed the test
2965 scripts to deal with BK's stripping CR characgters from text files,
2966 and changed the top-level Makefile.in to avoid including BitKeeper
2967 files when generating the source tarball.
2970 E2fsprogs 1.21 (June 15, 2001)
2971 ==============================
2973 Added new configure flags which allow a subset e2fsprogs to be built;
2974 this is most useful for boot floopies, since the resulting shared
2975 libraries and programs are slimmed down by removing features that
2976 aren't necessary for a boot floppy. The new flags that were added
2977 are: --disable-swapfs, which removes support for byte swapping old
2978 legacy PPC/68k filesystems, --disable-debugfs, which removes support
2979 for debugfs from the libext2fs library, --disable-imager, which
2980 removes support for the e2image program, and --disable-resizer, which
2981 removes support for resize2fs.
2983 E2fsck now prints the number of mounts or days elapsed since the last
2984 check when e2fsck is forced to check an otherwise clean filesystem.
2986 Tune2fs now prints an informative message about how often a filesystem
2987 will be checked when adding a journal to the filesystem, to remind the
2988 user that he/she may want to adjust those parameters using tune2fs
2991 Worked around hurd brain-damage which causes e2fsck to sometimes
2992 believe a filesystem is the root filesystem based on device numbers
2993 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
2996 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
2997 erroneous error with the -F option was specified.
2999 Fixed a ext3 recovery bug in the revoke handling; synchronized with
3002 Fixed two bugs in e2fsck's handling of dup block handling, dealing
3003 with relatively uncommon edge cases: a directory with an indirect
3004 block which is claimed by another file, and when the last inode in the
3005 filesystem has blocks claimed by another file.
3007 E2fsck now checks to see if the i_size field of a fast symlink is too
3008 big, and offers to clear the symlink if so.
3010 E2fsck now checks to see if i_size_high of special files is non-zero,
3011 and offers to clear i_size_high.
3013 Fix e2fsck's handling of incompatible journal flags so that the user
3014 has chance to abort, and then has the option to clear out the journal
3015 entirely. (Addresses Debian bug #98527.)
3017 Fixed a bug in fsck which could cause it to core dump if a mix of
3018 standard and non-standard device names are used in /etc/fstab.
3019 (Debian bug #100559)
3021 Fixed a bug in debugfs which caused read errors when copying a file to
3024 The debugfs set_super_value command can now modify the s_lastcheck field.
3026 Fixed a bug in lsattr and chattr which was accidentally introduced in
3027 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
3028 directories correctly because the change modified the layout of struct
3029 dirent to be incompatible with the libe2p shared library.
3031 Cleaned up the mke2fs manual page and included a discussion about why
3032 it's good to periodically check the filesystem even when journaling is
3038 Fix general gcc -Wall complaints.
3040 The types needed by the ext2 header files are now provided by
3041 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
3043 Integers are now preferred to longs when trying to find a 32-bit type
3044 in ext2_types.h. Also, if linux/types.h has already been defined,
3045 don't try to redefine the types.
3047 Fixed make depend script so that it automatically corrects the
3048 pathname cleanups performed by make -M, so I don't have to fix them up
3051 Fixed the d_loaddump test case to be more robust, and not depend on
3054 Removed debugfs's dependence on pread(), which was accidentally
3055 intrudced in e2fsprogs 1.20
3057 Fixed a performance bug in the libext2fs's icount routine; the size
3058 estimate of the icount array was incorrectly being calculated.
3060 Removed use of the badblocks compatibility functions in the e2fsprogs
3063 Added paranoia code which protects against strange cases where /etc
3064 isn't on the root filesystem, or if /etc/mtab doesn't exist.
3066 The header file ext2_types.h is now installed.
3068 Autoconf is used to determine when we are on big-endian machines,
3069 instead of doing run-time tests, to save a few bytes of code.
3071 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
3072 functions are no longer inline functions, which saves space and
3073 doesn't really cost any real performance.
3075 The ext2fs library no longer depends on the e2p library. (What need
3076 there was of it --- namely, fsetflags, was coded in-line).
3078 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
3079 when the user is stupid and tries compiling the package using "make
3082 Miscellaneous code cleanups:
3083 * Added missing files from Makefile.in's SRCS file, so that
3084 their dependencies would be properly calculated.
3085 * Removed redundant code
3086 * Fixed comments in code
3087 * Removed no-longer unneeded argsused #pragma.
3090 E2fsprogs 1.20 (May 20, 2001)
3091 =============================
3093 Add support for replaying the ext3 journal purely in user mode,
3094 including handling the orphaned inode list. Used code contributed by
3095 Andreas Dilger, with bug fixes and the orphaned inode handling done
3098 The mke2fs and tune2fs programs can create or modify a filesystem to
3099 include an ext3 journal. Tune2fs also can be used to remove an ext3
3100 journal from a filesystem.
3102 E2fsck will now check for the existence of a linked list of orphan
3103 inodes in the superblock, and clear those inodes before starting the
3104 rest of the filesystem check (but after the journal playback).
3106 E2fsck now validates the file descriptor passed to the -C option,
3107 which saves against the completion bar getting written to an
3108 unexpected location, such as the disk being checked. (Debian
3109 bug/wishlist #55220)
3111 E2fsck will now bump the filesystem revision number from zero to one
3112 if any of the compatibility bits are set.
3114 Fixed a bug where a badly corrupted directory on a big endian system
3115 could cause e2fsck to die with a bus error. The
3116 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
3117 the ext2 library now does alignment sanity checks on the rec_len field
3118 of the directory entry before using it.
3120 The ext2 library has been enhanced to make tune2fs safe to run on
3121 mounted filesystems. (Users could usually get away with using tune2fs
3122 on mounted filesystems before, but with the advent of ext3 and
3123 journaling, it became important to make tune2fs was *really* safe for
3124 use even when the filesystem being modified is mounted.) E2label is
3125 now implemented by tune2fs using an argv[0] dispatch, so that e2label
3126 is also now safe for use on mounted filesystems.
3128 Added a new program, e2image, which creates a backup of critical ext2
3129 filesystem data structures. The generated image file can be examined
3130 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
3131 the image file to help recover very badly damaged filesystems.
3133 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
3134 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
3135 large file when deciding whether or not the filesystem has large files.
3137 Fixed lsattr and chattr so that they work correctly on large files.
3138 (Fixes Debian bug #72690.)
3140 Removed limitation in get_device_size() which imposed a one terrabyte
3141 filesystem limitation. (Most 2.2 kernels still have a signed int
3142 problem which cause 1 TB block device limitation. Fortunately, the
3143 kernel patches to fix this are much easier than fixing the 2TB
3144 limitation in the kernel. :-)
3146 A max_mount_count of zero is now treated as if no mount count were
3147 set. (Previously, no mount count was indicated by using -1, and a
3148 mount count of zero caused e2fsck to always be run.)
3150 Mke2fs supports two new filesystem types largefile and largefile4.
3152 Mke2fs now adds some randomness in s_max_mount_count so that multiple
3153 filesystems won't be all checked at the same time under normal
3156 Fixed bug in the progress bar printing code which could cause e2fsck
3157 to core dump on an illegal filesystem.
3159 Fixed bug in fsck which could allow more than one instance of e2fsck
3160 to be printing a progress bar. (Debian bug #65267)
3162 Fsck using a UUID or a LABEL specifier will work even if devfs is
3163 compiled into the kernel and not mounted. If the pathnames in
3164 /proc/partitions are incorrect, fsck will search /dev for the correct
3165 device (using the new ext2fs_find_block_device library function).
3166 Fsck now also checks the RAID devices first so that they are properly
3167 found when they are in use. Support has also been added to support
3168 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
3170 Fixed a bug in fsck which caused it not deal properly with 16
3171 byte long filesystem labels.
3173 Fsck's -t option has been made a lot more flexible. The semantics for
3174 what happens if a comma-separated list to fsck has been regularized,
3175 and it is now possible to filter what filesystems will get checked
3176 based what is in the filesystem's fstab entry's option field. (Debian
3179 The dumpe2fs program can now print out the group description
3180 information in hex, and also prints the location of the superblock and
3181 block group descriptor for those block groups that have them.
3183 Mke2fs now clears the ext2 superblock before it starts creating a
3184 filesystem, so that the superblock magic number is only written if the
3185 filesystem creation process successfully completes.
3187 The debugfs program's stat command now pretty-prints the blocks used
3188 by an inode so that it's more compact and informative.
3190 The debugfs stats command now uses the same libe2p code (which is used
3191 by dumpe2fs) to print the superblock header information. This is more
3192 complete, and it avoids a bit of code duplication.
3194 Added a new debugfs command, set_super_value (ssv) which allows the
3195 user to set arbitrary superblock fields.
3197 Debugfs was extended to support inode numbers in hex (by prefixing
3198 them with 0x), and so that modify_inode can set the inode generation
3199 number. Also, there is now a new function command called logdump
3200 which will dump an ext3 journal.
3202 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
3205 Debugfs's dump command now stops immediately upon reporting a disk
3206 read error. (Fixed a bug in ext2fs_file_read library routine which
3207 caused debugfs not to stop.) (Debian bug #79163)
3209 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
3210 checked before /etc/mtab is used, since /proc/mounts is more likely to
3213 Added portability fixes for Solaris and Linux/ia64.
3215 Various manual pages were clarified and cleaned up. (Fixed debian
3216 bugs #63442, #67446, and #87216)
3222 The e2fsck message printer now supports %Iu and %Ig, which will print
3223 out the inode's user and group owners, respectively.
3225 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
3226 that no longer dependent on the system having the correct version of
3227 the kernel header files.
3229 Added a new function to libext2, ext2fs_find_block_device(), which
3230 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
3231 device given its device number.
3233 Added a new function to libext2, ext2fs_sync_device, which centralizes
3234 all of the places which might try to use the BLKFLSBUF or FDFLUSH
3235 ioctls (and usually failing to define them since the system header
3236 files don't usually do this for us, and we're trying to avoid usage of
3237 kernel include files now).
3239 Added new utility programs in tests/progs: random_exercise and
3240 hold_inode. They aren't built by default; they're useful for
3241 exercising ext3 filesystem code.
3243 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
3244 the filesystem close functions to only update the superblock, and to
3245 not touch the block group descriptors. Needed by tune2fs when
3246 modifying a mounted filesystem.
3248 Got rid of struct ext2fs_sb and replaced it with the standard struct
3249 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
3250 source (but not binary) compatibility of some users of the ext2
3251 library. Those applications should just simply do a global search and
3252 replace of struct ext2fs_sb with struct ext2_super_block, and include
3253 the new header file <ext2fs/ext2_fs.h> which defines it.
3255 The ino_t type has been renamed ext2_ino_t to protect applications
3256 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
3257 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
3258 unexpected ABI change.
3260 The Makefiles have been reworked so that "make check" can be run from
3261 the top-level Makefile.
3263 Fix general gcc -Wall complaints and removed dead code.
3265 Remove use of NOARGS, because we assume everyone does ANSI C these
3268 Added build-rpm script from sct.
3270 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
3273 New function ext2fs_flush_icache which must be called if the
3274 application program modifies the inode table blocks without going
3275 through ext2fs_write_inode() interface.
3277 New ext2fs_check_mount_point() function, which will return the mount
3278 point of a device if mounted.
3280 The io_channel abstraction now has an optional interface,
3281 io_channel_write_range, which allows specific byte ranges to be
3284 The unix_io IO channel now supports write-through caching, so that
3285 journal creation is more efficient.
3287 Added x86 assembly language routines to support byte swapping, to
3288 reduce executable size.
3290 Fixed bug in the utility program subst so that it's possible to
3291 replace a substitution variable with a zero-length string.
3293 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
3294 slipped into some of the problem number.
3296 E2fsprogs 1.19 (July 13, 2000)
3297 ==============================
3299 Release the resize2fs program since the timeout before it could
3300 be released under the GPL has finally expired.
3302 Add experimental support needed for the ext2 compression patches.
3303 This requires compiling e2fsprogs with the --enable-compression flag
3304 to the configure script.
3306 Added ext3 journalling support. E2fsck will run the journal (if
3307 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
3308 installed as a symlink to e2fsck. Fsck has been taught about ext3,
3309 and treats it the same as ext2 in terms of the progress bar logic.
3310 Dumpe2fs will display the superblock journaling information if the
3311 filesystem has a journal. The ext2 library will now permit opening an
3312 ext3 filesystem with the recovery flag set. This is necessary for
3313 on-line dump's to work correctly, but there may be issues with this
3314 working well since ext3 is much less agressive about syncing blocks to
3315 the filesystem, since they're safe on the journal.
3317 Tune2fs and e2fsck have been changed to allow the mount_count check to
3318 be disabled by setting max_mount_count to -1. (This was already
3319 supported by the kernel.)
3321 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
3322 are used for ext3 as well.
3324 Added internationalization support for e2fsprogs; must be enabled
3325 by passing --enable-nls to configure.
3327 Always use the provided ext2fs header files to insulate ourselves from
3328 kernel version changes. Which include files are used by e2fsprogs
3329 have also been cleaned up to improve portability.
3331 Limit the number of times that e2fsck updates the progress bar so that
3332 people who are booting using a 9600 baud console don't get swampped by
3335 Improved the loop detection algorithm in e2sck's pass #3 so that it is
3336 much, much faster for large filesystems with a large number of
3339 The memory footprint for e2fsck is now slightly smaller than before.
3341 E2fsck now checks if special devices have a non-zero size, and offers
3342 to clear the size field if it finds such an inode.
3344 E2fsck now checks if special devices have the append-only flag set,
3345 and offers to clear the inode.
3347 E2fsck now properly handles some "should never fail" cases during a
3348 bitmap copy in pass5.
3350 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
3352 E2fsck now calculates the correct location of the backup superblock in
3353 the case of filesystem blocksizes > 1k.
3355 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
3356 which normally didn't cause problems under most filesystem parameters,
3357 but could cause a valid superblock to be rejected in extreme cases.
3358 Other checks for validating superblock values were made more
3361 Added non-destructive write testing to the badblocks program, courtesy
3362 of David Beattie. The badblocks also now has an option to input the
3363 current set of bad blocks, so that known bad blocks are skipped to
3364 speed up the badblocks test. There is also a persistent rescan
3365 feature which causes badblocks to run until it has completed some
3366 number of passes without discovering any new bad blocks.
3368 Badblocks now checks to see if the device is mounted and refuses to do
3369 the tests involving writing to the device if it is mounted. Also,
3370 badblocks now allows the number of blocks to be checked to be
3371 defaulted to the size of the partition.
3373 Fixed a bug in fsck which didn't allow non-root users to be able to
3374 check filesystems if there were any LABEL= or UUID= entries in
3377 The Hurd doesn't support the filetype filesystem feature. The mke2fs
3378 program now makes sure that for the Hurd, the filestype feature is
3379 turned off. E2fsck will check to see if the filetype feature is
3380 turned on for Hurd filesystems, and offer to turn off the feature.
3382 Mke2fs now has a safety check to make sure the number of blocks do not
3383 exceed 32 bits even on a 64 bit platform.
3385 Really fixed a bug in fsck to allow "fsck -As" to run interactive
3386 fsck's. (For those people who like to do interactive fsck's in the
3389 Debugfs has a few new features: the rdump command, which will do a
3390 recursive dump of a directory and all of its contents, and the lcd
3391 command which does a local chdir (much like the ftp command of the
3392 same name). In addition, the debugfs program and the open_filesystem
3393 command now takes three new options: -b and -s, which allows the
3394 blocksize and superblock location to be specified, and the -c option
3395 which is used in catastrophic situations where the block group
3396 descriptors are corrupt. If the -c option is specified, debugfs will
3397 skip trying to read in the block and inode bitmaps.
3399 Debufs's lsdel command was fixed to handle bad blocks in the inode
3402 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
3405 General improvements in error messages
3407 - Mke2fs prints a sane error message if the partition size is zero
3408 (usually because the partition table wasn't reread by the
3409 kernel due to the partition being busy), instead of "invalid
3410 argument passed to ext2 library while initializing superblock".
3412 - Fsck now prints more self-explanatory message if an invalid UUID=
3413 or LABEL= specification is passed to it.
3415 UUID library changed to use the LGPL.
3417 Fixed a bug in the UUID library where very rapid calls to the
3418 time-based UUID generator could cause duplicate UUID's to be returned.
3419 This was not a problem for e2fsprogs, but it could be a problem for
3420 other users of the library.
3422 Make the UUID library more robust in the face of missing or an
3423 improper /dev/urandom or /dev/random files.
3425 Added some random portability fixes for Solaris.
3427 Some minor man page updates.
3429 Fixed a memory leak in the ss library.
3435 We now try to use lseek64 and open64 from the LFS if possible.
3437 The 3rd parameter in e2p's print_flags is now a flags word, instead of
3440 The mark and unmark bitmap functions now return the previous state of
3441 the bit that was being changed, which is useful for some speed
3444 The following functions have been added to enhance the badblocks list
3445 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3446 ext2fs_badblocks_equal.
3448 The ext2 header files now have the latest journalling fields to the
3451 The ext2fs_mkdir function in libext2fs now properly backs out of error
3452 conditions robustly.
3454 Cleaned up makefiles:
3455 - to cleanly compile with the -j flag.
3456 - so distclean removes all generated files.
3457 - so in case of an error while installing header files, the make aborts.
3459 Fix test_script so that it works correctly when compiling in the
3462 The random UUID generation routine has been made slightly better in
3463 the case where /dev/random doesn't exist. (Use of randomly-based UUID
3464 is still not recommended if /dev/random doesn't exist, however; it's
3465 better to use the time/ethernet MAC address UUID in this case.)
3467 Clean up the build process so it's more friendly in case of missing
3470 The ext2fs header file can now be #include'd into C++ programs.
3472 The e2p.h header file is now installed.
3474 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3478 E2fsprogs 1.18 (November 10, 1999)
3479 ==================================
3481 Fix a core dumping bug in e2fsck if an imagic inode is present or
3482 (more rarely) if the filesystem is badly corrupted enough that e2fsck
3483 has to restart pass 1 processing. E2fsck now closes the filesystem
3484 before freeing a large number of its data structures, so in the case
3485 of future memory faults, at least the fixed filesystem will be fully
3488 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3489 imagic inode, it will offer to clear the imagic flag.
3491 E2fsck will now offer to clear the immutable flag on special files
3492 (device/socket/fifos) when running it in non-preen mode.
3494 E2fsck will now set the filetype when creating /lost+found, and when
3495 connected orphaned inodes to /lost+found.
3497 Debugfs's ncheck and icheck commands now handles the case where there
3498 are bad blocks in the inode table without bombing out.
3500 The badblocks list processing code has been made more efficiently for
3501 appending a large number of (ordered) badblocks to the badblocks list.
3503 Some minor man page updates.
3505 Fsck now allows interactive e2fsck's when using fsck -As (not a common
3506 mode, but some people like to do this in boot scripts for silly reasons).
3511 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3512 with the problem code convention.
3514 The badblocks list regression test program has been updated to work
3515 with previously made API name changes.
3517 The ext2fs_free() command now uses the new badblocks API to avoid
3518 using the compatibility layer.
3520 Added new regression test cases; the run_e2fsck test script now
3521 supports the ability for a test case to run a prepratory command
3522 before running e2fsck.
3524 E2fsprogs 1.17 (October 26, 1999)
3525 =================================
3527 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3530 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3531 thus potentially causing problems if a binary UUID contained a NULL
3534 E2fsck now uses stricter checks for directory entries in pass 2:
3535 zero-length filenames are not allowed; neither are 8 byte long
3538 The debugfs "dirty" command now clears the filesystem valid bit.
3539 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
3540 bit in the in-core superblock image. The new functionality is more
3541 what the user expects, and is more useful.)
3543 Added a debugging hook to test parallel fsck; if the environment
3544 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3545 will be checked in parallel when they normally would not be.
3550 Fixed some #ifdef's for compilation under the Hurd OS.
3552 Fixed minor W2K compatibility problems.
3554 Fixed some miscellaneous GCC warnings.
3557 E2fsprogs 1.16 (October 22, 1999)
3558 =================================
3560 Fixed a race condition bug in fsck; when printing a progress bar, if
3561 checking multiple filesystems in parallel, it was possible for fsck to
3562 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3563 handler, which would cause it to terminate with a signal 10.
3565 E2fsck now properly handles filesystems that have the
3566 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3567 filesystem into using or not using FILETYPE feature.
3569 E2fsck now properly handles filesystems that have the IMAGIC feature
3570 turned on (this is used on Linux AFS servers).
3572 The mke2fs program now creates filesystems that have the filetype and
3573 sparse_superblock features enabled by default, unless it is run on a
3574 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3575 so there is now a new flag -O which allows the user to specify with
3576 which features she would like to create the filesystem; "mke2fs -O
3577 none" will create a filesystsem compatible with 2.0 kernels.
3579 The tune2fs program now has a -O option which allows the user to set
3580 and reset "safe" filesystem features. Currently, the only ones which
3581 allows to be modified are the filetype and sparse_superblock features.
3582 Note setting or clearing either feature will require running e2fsck on
3583 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3584 requires that there is enough free space on the filesystem for the
3585 extra superblocks which will be created by e2fsck.)
3587 Debugfs can now set and print filesystem features in the superblock
3588 using the "features" command. Dumpe2fs will print out the complete
3589 set of features when listing the superblock.
3591 Dumpe2fs has new options -f (force) and -h (header-only).
3593 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3594 message to come up. This could happen when decrementing or
3595 incrementing a link count could result in an overflow.
3597 Fixed a bug in e2fsck where the block count on the lost+found
3598 directory would not be properly incremented when the directory was
3599 expanded to the point where an indirect block needed to be allocated.
3601 E2fsck now makes some additional sanity checks on the superblock to
3602 avoid crashing or giving a memory allocation error if some of the
3603 values in the superblock are unresonable (but the superblock otherwise
3606 Fixed a bug in e2fsck where a very badly corrupted filesystem might
3607 require two passes to completely fix the filesystem. This happened if
3608 an inode claimed blocks that was part of the filesystem metadata
3609 (typically, when garbage was written into an inode table or indirect
3610 block, since this kind of filesystem corruption normally doesn't
3613 On the Alpha, glibc declares st_flags although it isn't actually used;
3614 the configure script was improved to detect this case so that
3615 e2fsprogs can avoid using the non-functional stat field.
3617 The manual pages were updated to use a more consistent formatting
3618 style consistent with standard Unix man pages. Mke2fs's man page
3619 added documentation for a few previously undocumented options.
3621 Fixed minor display bugs in tune2fs and mke2fs.
3626 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
3628 Added features to parse and print feature strings into the e2p library.
3629 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
3631 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
3632 whose directory entries contain proper filetype information if the
3633 filesystem supports it.
3635 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
3636 the directory entry filetype information. This is used to set the
3637 directory entry filetype information if the filesystem supports it.
3639 Fixed a bug in ext2fs_expand_dir() where the block count in a
3640 directory's inode would not be properly incremented when the directory
3641 was expanded to the point where an indirect block needed to be
3645 E2fsprogs 1.15 (July 18, 1999)
3646 ==============================
3648 Add configuration checks so that e2fsprogs will compile cleanly on
3649 Linux 2.3 kernels that have renamed i_version to i_generation.
3651 E2fsck now prints a progress/completion bar (and not just a simple
3652 spinner) if the -C0 option is requested or if it receives a SIGUSR1
3653 signal. Fsck will automatically manage the (potentially muliple)
3654 e2fsck processes to print completion bars if it is given a -C option,
3655 with the right thing happening if multiple filesystems are being
3656 checked in parallel.
3658 Mke2fs now has better automatic hueristics to determine the filesystem
3659 parameters to be used for a particular filesystem. Added a new option
3660 -T which allows the user to specify how the filesystem is to be used,
3661 which helps mke2fs do a better job selecting the filesystem parameters.
3663 Mke2fs now creates revision 1 filesystems by default, and with the
3664 sparse superblock feature enabled. The sparse superblock feature is
3665 not understood by Linux 2.0 kernels, so they will only allow read-only
3666 mounts of filesystems with this sparse superblocks.
3668 Fix bug where if /dev/null couldn't be opened (should never happen),
3669 e2fsck would hang in a tight loop.
3671 Make e2fsck handle the case where /lost+found isn't a directory.
3673 E2fsck now uses mallinfo if it exists to get accurate statistics about
3676 Fix bug in e2fsck where it wouldn't check to see if a disconnected
3677 inode had any problems before connecting it to /lost+found.
3679 Add check to e2fsck so it makes sure that total number of inodes in
3680 the filesystem is a sane number.
3682 Fix fencepost error when clearing an the end of the block bitmap which
3683 caused the last block in the bitmap not to get cleared.
3685 Cleaned up a number of messages in e2fsck:
3686 * The message "Group's #'s copy of the group descriptor..."
3687 was fixed so that the correct number would be displayed.
3688 * Added missing space in the "disk write-protected" error messsage
3689 * Cleaned up the error message printed when a non-interactive
3690 e2fsck needs to abort a check because the filesystem
3691 appears to be mounted.
3693 Added a new command-line utility, uuidgen, which will create and print
3696 Make debugfs's icheck command more robust by checking to make sure an
3697 inode has valid blocks before interarting over the inode's blocks.
3699 UUID generation now uses a random-based scheme whenever possible to
3700 prevent potential privacy problems.
3702 Man pages for all of the UUID functions in the lirbary were added.
3704 Fixed bug in fsck so it won't coredump if a filesystem not in
3705 /etc/fstab is given to it.
3707 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
3708 that most of the other mount utilities understands.
3710 Mke2fs will make a filesystem even if it appears mounted if the force
3713 Dumpe2fs has new command-line options which allow a filesystem expert
3714 to specify the superblock and blocksize when opening a filesystem.
3715 This is mainly useful when examining the remains of a toasted
3718 The badblocks program has been updated to display correctly on disks
3719 with large block numbers.
3721 The badblocks program no longer gives spurious errors when errors
3722 occur on non-block boundaries, which is common if the blocksize is
3725 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
3726 MKE2FS_SYNC environment variable is set. This is to work around a VM
3727 bug in the 2.0 kernel. I've heard a report that a RAID user was able
3728 to trigger it even using a 2.2 kernel, but hopefully it will not be
3729 needed for most Linux 2.2 users.
3731 Fixed miscellaneous documentation and man pages.
3736 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
3737 in e2fsck's pass1.c really should have been static.
3739 The return value of the uuid_compare() function was changed to make it
3740 match with the convetions used by strcmp, memcmp, and Paul Leach's
3741 UUID sample document.
3743 The "make depend" process has now been made more automated; it now
3744 automatically word-wraps the dependencies, and only replaces source
3745 Makefile.in if there has been a change in the dependencies. Also, a
3746 top-level "make depend" now recurses through all the subdirectories
3749 The Makefile in .../util has been changed so that subst is built using
3750 the native C compiler during a cross-compilation, since the subst
3751 program is only used during the build process. Also add an explicit
3752 rule to build util/subst by cd'ing to the correct directory and
3755 The man directories are defined in terms mandir, so that the configure
3756 script can override the location of the manual pages.
3758 The config files have been updated to recognize new machine types for
3759 both the i386 and alpha families.
3761 Fsck has been modified so that it will accurately create an
3762 fsck_instance even when the noexecute flag is set. This allows for
3763 accurate debugging of the fsck pass structure. Also, when the verbose
3764 flag is given twice, fsck will print debugging information about when
3765 fsck is waiting for jobs to finish.
3768 E2fsprogs 1.14 (January 9, 1999)
3769 ================================
3771 Fix the fstab parsing code so that it can handle blank lines and
3772 comment characters. Also, missing pass numbers need to be treated as
3775 Fixed a bug in e2fsck where under some circumstances (when e2fsck
3776 needs to restart processing after fixing an egregious inconsistency)
3777 it would try to access already freed memory.
3779 E2fsck now prints non-printable characters in directory entries and
3780 pathnames using '^' and 'M-' notation.
3782 Fixed chattr so that it will ignore symbolic links when doing
3783 recursive descent traversals. For both chattr and lsattr, no longer
3784 print the version string unless the -V option is given.
3786 Allow the system administrator to directly specify the number of
3787 inodes desired in the filesystem, for some special cases where this is
3790 Fix portability problems so that e2fsprogs can be compiled under Linux
3791 1.2 systems and Solaris systems.
3793 Update the config.guess file with a more recent version that will
3794 identify newer Linux platforms.
3799 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
3800 an inode number of zero is passed to them.
3802 E2fsprogs 1.13 (December 15, 1998)
3803 ==================================
3805 Fixed a bug in debugfs where an error messages weren't getting printed
3806 when the ext2 library routines to read inodes returned errors in the
3807 stat, cmri and rm commands.
3809 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
3810 provided, it won't create an inode table smaller than the minimum
3811 number of inodes required for a proper ext2 filesystem.
3813 Fsck now parses the /etc/fstab file directly (instead of using
3814 getmntent()), so that it can distinguish between a missing pass number
3815 field and pass number field of zero. This caused problems for
3816 diskless workstations where all of the filesystems in /etc/fstab have
3817 an explicit pass number of zero, and fsck could not distinguish this
3818 from a /etc/fstab file with missing pass numbers.
3820 E2fsck will create a /lost+found directory if there isn't one in the
3821 filesystem, since it's safer to create the lost+found directory before
3824 Fixed e2fsck so that it would detect bogus immutable inodes which
3825 happen to be sockets and FIFO files, and offer to clear them.
3827 If a filesystem has multiple reasons why it needs to be checked, and
3828 one of the reasons is that it is uncleanly mounted, e2fsck will print
3829 that as the reason why the filesystem is being checked.
3831 Cleaned up the output routines of mke2fs so that it doesn't overflow
3832 an 80 column display when formating really big filesystems.
3834 Added a sanity check to e2fsck to make sure that file descriptors 0,
3835 1, 2 are open before opening the hard disk. This avoids a problem
3836 where a broken program might exec e2fsck with those file descriptors
3837 closed, which would cause disastrous results if the kernel returns a
3838 file descriptor for the block device which is also used by FILE *
3841 Fixed up the e2fsck progress reporting functions so that the values
3842 reliably reach 100% at the completion of all of the e2fsck passes.
3844 Fixed minor documentation bugs in man pages and usage messages.
3849 Fixed a number of lint warnings in the ext2fs library and potential
3850 portability problems from other OS's header files that might define
3851 CPP macros for names like "max" and "min".
3853 ext2fs_badblocks_list_add() has been made more efficient when it needs
3854 to grow the bad blocks list.
3856 Fixed a bug in e2fsck which caused it to dereference a freed pointer
3857 just before exiting.
3859 Fixed the substition process for generating the mk_cmds and compile_et
3860 scripts so that they will work outside of the build tree.
3862 Add sanity check to e2fsck so that if an internal routine
3863 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
3864 and causing a core dump. This should never happen, but...
3866 E2fsprogs 1.12 (July 9, 1998)
3867 ==================================
3869 E2fsprogs now works with glibc (at least with the version shipped wtih
3870 RedHat 5.0). The ext2fs_llseek() function should now work even with
3871 i386 ELF shared libraries and if llseek() is not present. We also
3872 explicitly do a configure test to see if (a) llseek is in libc, and
3873 (b) if llseek is declared in the system header files. (See standard
3874 complaints about libc developers don't understand the concept of
3875 compatibility with previous versions of libc.)
3877 The ext2fs library now writes out the block group number in each of
3878 the superblock copies. This makes it easier to automatically
3879 determine the starting block group of the filesystem when the block
3880 group information is trashed.
3882 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
3883 which means that e2fsprogs will ignore the high 8 bits of the
3884 directory entry's name_len field, so that it can be used for other
3887 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
3888 E2fsprogs will now support filesystems with 64-bit sized files.
3890 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
3892 Added new program "e2label", contributed by Andries Brouwer. E2label
3893 provides an easy-to-use interface to modify the filesystem label.
3895 Fixed bug so that lsattr -v works instead of producing a core dump.
3897 Fixed a minor bug in mke2fs so that all groups with bad superblock
3898 backup blocks are printed (not just the first one).
3900 Mke2fs will check the size of the device, and if the user specifies a
3901 filesystem size larger than the apparent size of the device it will
3902 print a warning message and ask if the user wants to proceed.
3904 E2fsck has a new option -C, which sends completion information to the
3905 specified file descriptor. For the most part, this is intended for
3906 programs to use, although -C 0 will print a spinning character to the
3907 stdout device, which may be useful for users who want to see something
3908 happening while e2fsck goes about its business.
3910 Fixed a bug in e2fsck which could cause a core dump when it needs to
3911 expand the /lost+found directory, and sometimes the bitmaps haven't
3912 been merged in. Also fixed a related bug where ext2fs_write_dir_block
3913 was used to write out a non-directory block. (Which would be bad on a
3914 non-Intel platform with byte swapping going on.)
3916 Fixed bug in e2fsck where it would print a "programming error" message
3917 instead of correctly identifying where a bad block was in used when
3918 the bad block was in a non-primary superblock or block group
3919 descriptor. Also fixed a related bug when sparse superblocks are in
3920 use and there is a bad block where a superblock or block group
3921 descriptor would have been in a group that doesn't include a
3924 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
3925 the block group descriptor table is corrupt, it was possible to try to
3926 allocate a huge array, fail, and then abort e2fsck.
3927 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
3928 and subsitutes reasonable values if the descriptors are obviously bogus.
3930 If e2fsck finds a device file which has the immutable flag set and the
3931 i_blocks beyond the normal device number are non-zero, e2fsck will
3932 offer to remove it, since it's probably caused by garbage in the inode
3935 When opening a filesystem, e2fsck specially checks for the EROFS error
3936 code, and prints a specific error message to the user which is more
3939 If the filesystem revision is too high, change the e2fsck to print
3940 that this is either because e2fsck is out of date, or because the
3941 superblock is corrupt.
3943 E2fsck now checks for directories that have duplicate '.' and '..'
3944 entries, and fixes this corruption.
3946 E2fsck no longer forces a sync of the filesystem (with attendant sleep
3947 calls) at all times. The ext2fs_flush() function now performs a sync
3948 only if it needed to write data blocks to disk.
3950 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
3951 certain errors would not be properly reported.
3953 Updated and expanded a few points in the man pages which users
3954 complained wheren't explicit enough.
3956 Added special case byte-swapping code if compiling on the PowerPC, to
3957 accomodate the strange big-endian variant of the ext2 filesystem that
3958 was previously used on the PowerPC port.
3964 Removed C++ keywords from the ext2fs libraries so that it could be
3967 E2fsck's internal organization has now been massively reorganized so
3968 that pass*.c don't have any printf statements. Instead, all problems
3969 are reported through the fix_problem() abstraction interface. E2fsck
3970 has also been revamped so that it can be called as a library from a
3973 Added new fileio primitives in libext2fs for reading and writing
3974 files on an unmounted ext2 filesystem. This interface is now used by
3977 Added a new libext2fs function for mapping logical block numbers of
3978 a file to a physical block number.
3980 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
3981 a block, zeros it, and updates the filesystem accounting records
3984 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
3985 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
3987 The libext2fs functions now use a set of memory allocation wrapper
3988 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
3989 instead of malloc, free, and resize. This makes it easier for us to
3990 be ported to strange environments where malloc, et. al. aren't
3991 necessarily available.
3993 Change the libext2fs fucntion to return ext2-specific error codes
3994 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
3995 and depending on the existence of system error codes (such as EEXIST
3998 Renamed io.h to ext2_io.h to avoid collision with other OS's header
4001 Add protection against ext2_io.h and ext2fs.h being included multiple
4004 The types used for memory lengths, etc. have been made more portable.
4005 In generla, the code has been made 16-bit safe. Added Mark
4006 Habersack's contributed DOS disk i/o routines.
4008 Miscellaneous portability fixes, including not depending on char's
4011 The io_channel structure has a new element, app_data, which is
4012 initialized by the ext2fs routines to contain a copy of the filesystem
4015 ext2fs_check_directory()'s callback function may now return the error
4016 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
4017 really do the checking, despite the presence of the callback function.
4020 E2fsprosg 1.11 (June 17, 1997)
4021 ==============================
4023 Fixed e2fsck to detect (previously ignored) conflicts between the
4024 superblock or block group descriptors and block bitmaps, inode
4025 bitmaps, and inode tables.
4027 Fixed bug in e2fsck so that when the message printed out when a block
4028 or inode bitmap conflicts with other data, it has the correct group
4031 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
4032 to badblocks. This meant that not all of the filesystem was being
4033 tested for bad blocks!
4035 Fixed an array boundary overrun case which cropped up in
4036 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
4039 Adjusted the number of columns printed by mke2fs when displaying the
4040 superblock backups to avoid running over 80 columns when making a
4041 really big filesystem.
4043 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
4044 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
4045 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
4050 Fixed install rule in lib/ss so that ss_err.h is actually getting
4053 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
4054 bassed back to the caller.
4056 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
4057 setting the current inode number (which meant this function wasn't
4060 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
4061 blocks in the bitmap when increasing the size of the bitmap.
4063 Changed the initial number of blocks allocated by ext2fs_init_dblist()
4064 to be more realistic.
4066 Added a new function ext2fs_allocate_group_table, which sets up the
4067 group descriptor information (and allocates inode and block bitmaps,
4068 and inode tables for a particular group). The function was created by
4069 factoring out code form ext2fs_allocate_tables().
4071 Added a new function ext2fs_move_blocks which takes a bitmap of the
4072 blocks to be moved, and moves them to another location on the
4075 Make the unix_io channel's io_channel_flush implementation calls sync()
4076 to to flush the kernel buffers to disk.
4078 Added a new function ext2fs_dblist_count returns the number of
4079 directory blocks in dblist.
4082 E2fsprogs 1.10 (April 24, 1997)
4083 ===============================
4085 Mke2fs once again defaults to creating revision #0 filesystems, since
4086 people were complaining about breaking compatibility with 1.2 kernels.
4087 Warning messages were added to the mke2fs and tune2fs man pages that
4088 the sparse superblock option isn't supported by most kernels yet (1.2
4089 and 2.0 both don't support parse superblocks.)
4091 Added new flag to mke2fs, -R <raid options>, which allows the user to
4092 tell mke2fs about the RAID configuration of the filesystem. Currently
4093 the only supported raid option is "stride" which specifies the width
4096 Fixed bug in e2fsck where pass1b would bomb out if there were any
4097 blocks marked bad in the inode table.
4099 Fixed rare bug in mke2fs where if the user had a very unlucky number
4100 of blocks in a filesystem (probability less than .002) the resulting
4101 filesystem would be corrupt in the last block group.
4103 Fixed bug where if e2fsck tried to allocate a block to fix a
4104 filesystem corruption problem and the filesystem had no free blocks,
4105 ext2fs_new_block() would loop forever.
4107 The configure script now checks explicitly to see if "-static" works,
4108 since that can't be assumed to be true --- RedHat doesn't install
4109 libc-static by default.
4111 Fixed bug in libext2's block iterator functions where under some
4112 cirmcustances, file with holes would cause the bcount parameter to the
4113 callback function to be incorrect. This bug didn't affect any of
4114 e2fsprogs programs, but it was discovered by Paul Mackerras, the
4115 author of the PPC boot loader.
4117 Removed use of static variables to store the inode cache in libext2fs.
4118 This caused problems if more than one filesystem was accessed via
4119 libext2fs (static variables in libraries are generally a bad idea).
4120 Again, this didn't affect e2fsprogs programs, but it was discovered by
4123 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
4124 will compile cleanly with 1.2.13 kernels (even with a.out shared
4130 Added new functions to duplicate an ext2 filesystem handle, and its
4131 associated substructure. New functions: ext2fs_dup_handle(),
4132 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
4133 Other structures, such as the io_channel and the inode_cache, now have
4134 a ref count so that they only get freed when they are no longer used
4135 by any filesystem handle. (These functions were added as part of the
4136 development effort for an ext2 resizer).
4138 E2fsprogs 1.09 (April 14, 1997)
4139 ===============================
4141 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
4142 accidentally introduced in the 1.08 release. The overhead calculation
4143 was accidentally removed, which caused ext2fs_initialize() to not
4144 notice when the filesystem size needed to be adjusted down because
4145 there wasn't enough space in the last block group.
4147 Fixed bug in version parsing library routine; it was always parsing
4148 the library version string, instead of using the passed-in string.
4150 Clarified chattr man page.
4152 E2fsprogs 1.08 (April 10, 1997)
4153 ===============================
4155 E2fsck 1.07 was very slow when checking very large filesystems with a
4156 lot of files that had hard links (i.e., news spools). This was fixed
4157 by seriously revamping the icount abstraction. Added a formal test
4158 suite for the icount abstraction.
4160 Debugfs now has a "-l" option to the "ls" command, which lists the
4161 inode number, permissions, owner, group, size, and name of the files
4164 Fix a bug in e2fsck where when a directory had its blocks moved to
4165 another location during the pass 1b processing, the directory block
4166 list wasn't updated, so pass 2 wouldn't check (and correct) the
4167 correct directory block.
4169 E2fsck will now treat inodes which contain blocks which are claimed by
4170 the filesystem metadata by treating them as multiply claimed blocks.
4171 This way, the data in those blocks can be copied to a new block during
4172 the pass 1b--1d processing.
4174 E2fsck will attempt to determine the correct superblock number and
4175 display it in the diagnostic and warning messages if possible.
4177 Add support for a new (incompatible) feature, "sparse_super". This
4178 feature reduces the number of blocks which contain copies of backup
4179 superblocks and block group descriptors. (It is only an incompatible
4180 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
4181 support a new -s option; e2fsck will recognize filesystems built with
4182 this feature turned on.
4184 E2fsck now checks the library to make sure is the correct version,
4185 using new library functions. (This helps to diagnose incorrectly
4186 installed e2fsprogs distributions.)
4188 Dumpe2fs now prints more information; its now prints the the
4189 filesystem revision number, the filesystem sparse_super feature (if
4190 present), the block ranges for each block group, and the offset from
4191 the beginning of the block group.
4193 Mke2fs now distributes the inode and block bitmap blok so that the
4194 won't be concentrated in one or two disks in RAID/striping setups.
4195 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
4196 choose the largest blocks per group that be chosen. (For 2k blocks,
4197 you can have up to 16384 blocks/group; for 4k blocks, you can have up
4198 to 32768 blocks/group.) Previously mke2fs would not allow
4199 specification of more than 8192 blocks per group, even if you were
4200 using a 2k or 4k block group.
4205 Added a new function ext2fs_create_icount2() which takes a "hint"
4206 argument. This hint argument presets the icount array with the list
4207 of inodes which actually need to be in the icount array. This really
4208 helps to speed up e2fsck.
4210 Added a new function ext2fs_icount_validate() which checks the rep
4211 invariant for the icount structure. This is used mostly for testing.
4213 The error mesasage given when a bad inode number is passed to
4214 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
4215 EXT2FS_UNMARK_ERROR).
4217 Added a new function ext2fs_set_dir_block which sets the block of a
4218 dblist entry, given the directory inode and blockcnt.
4220 Added a new function ext2fs_get_library_version() which returns the
4221 current library version, and ext2fs_parse_version_string() which
4222 returns a version number based on a e2fsprogs version string.
4224 The icount functions will return EINVAL if the passed in inode number
4227 E2fsprogs 1.07 (March 9, 1997)
4228 ==============================
4230 E2fsck is now uses much less memory when checking really large
4231 filesystems (or rather, filesystems with a large number of inodes).
4232 Previously a filesystem with 1 million inodes required 4 megabytes of
4233 memory to store inode count statistics; that storage requirement has
4234 now been reduced to roughly half a megabyte.
4236 E2fsck can now properly deal with bad blocks appearing inside the
4237 inode table. Instead of trying to relocate the inode table (which
4238 often failed because there wasn't enough space), the inodes in the bad
4239 block are marked as in use.
4241 E2fsck will automatically try to use the backup superblocks if the
4242 primary superblocks have a bad magic number or have missing meta-data
4243 blocks (or meta-data blocks which are out of range).
4245 E2fsck's pass 3 has been made more efficient; most noticeable on
4246 filesystems with a very large number of directories.
4248 Completely revamped e2fsck's system of printing problem reports. It
4249 is now table driven, to make them more easily customizeable and
4250 extendable. Error messages which can be printed out during preen mode
4251 are now one line long.
4253 Fixed e2fsck's filesystem swapping code so that it won't try to swap
4254 fast symbolic links or deleted files.
4256 Fixed e2fsck core dumping when fixing a filesystem which has no
4257 directories (not even a root directory).
4259 Added a check to e2fsck to make sure that the length of every
4260 directory entry is a multiple of 4 (since the kernel complains if it
4263 Added a check to e2fsck to make sure that a directory entry isn't a
4264 link to the root directory, since that isn't allowed.
4266 Added a check to e2fsk to now make sure the '.' and '..' directory
4267 entries are null terminated, since the 2.0 kernel requires it.
4269 Added check to write_bitmaps() to make sure the superblock doesn't get
4270 trashed if the inode or block bitmap is marked as being block zero.
4272 Added checking of the new feature set fields in the superblock, to
4273 avoid dealing with new filesystem features that this package wasn't
4276 Fixed a fencepost error in ext2fs_new_block() which would occasionally
4277 try to allocate a block beyond the end of a filesystem.
4279 When the UUID library picks a random IEEE 802 address (because it
4280 can't find one from a network card), it sets the multicast bit, to
4281 avoid conflicting with a legitimate IEEE 802 address.
4283 Mke2fs now sets the root directory's owner to be the real uid of the
4284 user running mke2fs. If the real uid is non-zero, it also sets
4285 the group ownership of the root directory to be the real group-id of
4286 the user running mke2fs.
4288 Mke2fs now has more intelligent error checking when it is given a
4289 non-existent device.
4291 When badblocks is given the -vv option, it now updates the block that
4292 it is currently testing on every block.
4294 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
4295 currently correctly if PATH wasn't already set.
4297 Shared libraries now built with dependencies. This allows the shared
4298 library files to be used with dlopen(); it also makes the transition
4299 to libc 6 easier, since ld.so can tell which libc a particular shared
4300 library expects to use.
4305 Added new abstraction (defined in dblist.c) for maintaining a list of
4306 blocks which belongs to directories. This is used in e2fsck and other
4307 programs which need to iterate over all directories.
4309 Added new functions which test to see if a contiguous range of blocks
4310 (or inodes) are available. (ext2fs_*_bitmap_range).
4312 Added new function (ext2_inode_has_valid_blocks) which returns true if
4313 an inode has valid blocks. (moved from e2fsck code).
4315 Added new function (ext2fs_allocate_tables) which allocates the
4316 meta-data blocks as part of initializing a filesystem. (moved from
4319 Added a new I/O manager for testing purposes. It will either allow a
4320 program to intercept I/O requests, or print debugging messages to
4321 trace the activity of a program using the I/O manager.
4323 The badblocks_list functions now store the bad blocks in a sorted
4324 order, and use a binary search to speed up badblocks_list_test.
4326 The inode scan function ext2fs_get_next_inode() may now return a soft
4327 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
4328 those cases where part of an inode table is missing or there is a bad
4329 block in the inode table.
4331 Added a new function (ext2fs_block_iterate2) which adds new arguments to
4332 the callback function to return a pointer (block and offset) to the
4333 reference of the block.
4335 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
4336 application to jump to a particular block group while doing an inode
4339 The badblocks list functions were renamed from badblocks_* to
4340 ext2fs_badblocks_*. Backwards compatibility functions are available
4341 for now, but programs should be modified to use the new interface.
4343 Some of the library functions were reorganized into separate files to
4344 reduce the size of some programs which statically link against the
4347 Put in some miscellaneous fixes for the Alpha platform.
4350 E2fsprogs 1.06 (October 7, 1996)
4351 ================================
4353 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
4354 smash the backup copies in ext2fs_close(). (The problem was that when
4355 e2fsck -p discovered the problem, while it was closing the filesystem
4356 and exiting, it was also blowing away the backup superblocks on the
4357 disk, which was less than friendly.) We now make it the case that we
4358 only write out the backup superblock and the back block descriptors if
4359 the filesystem is completely free from problems.
4361 Fixed a bug in block_interate in the lib/ext2fs library which caused
4362 e2fsck to fail on GNU Hurd-created filesystems.
4364 Add support for Linux/FT's bootloader, which actually uses
4365 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
4368 Add support for the "A" (no atime update) attribute. (Note: this
4369 attribute is not yet in production kernels.)
4371 The test suite is not automatically run when doing a "make all" from
4372 the top level directory. Users should manually run "make check" if
4373 they wish to run the test suite.
4375 Upon a preenhalt(), make the printed message more explicit that
4376 running e2fsck "MANAULLY" means without the -p or -a options.
4378 In e2fsck, if a disconnected inode is zero-length, offer to clear it
4379 instead of offering to connect it to lost+found.
4381 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
4382 e2fsck to be run over it, change e2fsck to explicitly display this
4385 For dumpe2fs and e2fsck, cause the -V option to print out which
4386 version of the ext2fs library is actually getting used. (This will
4387 help detect mismatches of using a 1.06 utility with a 1.05 library,
4393 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
4394 the naming convention.
4396 In ext2fs_initialize(), make sure the description for the inode bitmap
4397 is correctly initialize.
4399 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4401 E2fsprogs 1.05 (September 7, 1996)
4402 ==================================
4404 Add support for new fields in the ext2 superblock --- volume name,
4405 volume UUID, and last mounted field. Dumpe2fs displays these fields,
4406 tune2fs and mke2fs allows you to set them. E2fsck will automatically
4407 generate a UUID for those volumes that don't have them.
4409 Put in support for e2fsck to recognize HURD specific ext2 features ---
4410 most notably, the translator block. The e2fsprogs tools will now use
4411 the creator_os field in the superblock to correctly handle different
4412 OS-specific variants of the ext2 filesystem.
4414 E2fsck now fixes inodes which have a the deletion time set, but which
4415 have a non-zero i_link_count field by offering to clear the deletion
4416 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4417 ext2 kernel behavior) and offered to unlink the file.
4419 If e2fsck sets the clean bit, but nothing else, set the exit code
4420 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4421 set the filesystem valid bit when it was previously cleared. :-) This
4422 was needed to make the HURD fsck driver happy.
4424 If the user refuses to attach an unattached inode, e2fsck will no
4425 longer set the inode's link count. Otherwise, the inode would end up
4426 getting marked as unused, which might cause loss of data later.
4428 Make the message issued by e2fsck when the superblock is corrupt less
4429 confusing for users. It now mentions that another reason for the
4430 "corrupt superblock" message might be that the partition might not be
4431 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4433 Make the libext2 library more robuest so that e2fsck won't coredump on
4434 an illegal superblock where the blocksize is zero. (f_crashdisk is
4437 By default, create filesystems where the default checkinterval is 6
4438 months (180 days). Linux servers can be robust enough that 20 reboots
4439 can be a long, long time.
4441 Added configure flag --enable-old-bitops, which forces the bitops to
4442 use the old (native) bitmask operations. By default on the sparc
4443 platform, the standard ext2 bit ordering is now used.
4445 Added a new feature to e2fsck to byte-swap filesystems; this can be
4446 used to convert old m68k filesystems to use the standard byte-order
4447 storage for the superblock, inodes, and directory blocks. This
4448 function is invoked by using the '-s' option to e2fsck.
4450 Debugfs's "dump" command has been enhanced so that it writes out the
4451 exact size of the file so that the nulls at the end of the file are
4452 eliminated. The command also accept a new "-p" option which will
4453 attempt preserve to preserve the ownernship, permissions, and
4454 file modification/access times.
4456 Debugfs has two new options, -f and -R. The -R option allows the user
4457 to execute a single debugfs command from the command line. The -f
4458 option allows the user to specify a "command file" containing debugfs
4459 commands which will get executed.
4461 Dumpe2fs now pretty prints the check interval, instead of just
4462 printing the check interval as a number of seconds.
4464 Fix bugs in debugfs: the params command when no filesystem is opened
4465 no longer causes a core dump. It is now possible to unlink a file
4466 when a pathame containing a '/' is specified.
4468 Tune2fs has a new -C option which sets the number of times the
4469 filesystem has been mounted.
4471 Fix the chattr '-v' option so that it actually works. Chattr was
4472 being buggy about the -v option parsing.
4477 The directory lib/uuid contains a set of library routines to generate
4478 DCE compatible UUIDs.
4480 Extended ext2fs_namei() to handle symbolic links. Added new function
4481 ext2fs_nami_follow() which will follow last symbolic link in the case
4482 where the pathname points to a sym link.
4484 The ext2fs_block_iterate function will now return the HURD translator
4485 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4486 iterator to return data blocks only. The ext2fs.h file now defines
4487 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4488 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4489 count field of the iterator callback function.
4491 The test script driver now takes an optional second argument, which is
4492 the test case to be run. This allows you to run a test case without
4493 needing to run the entire test suite.
4495 On Linux ELF systems, install the .so files in the correct places
4496 (/usr/lib). The .so files must be stored in the same directory as the
4499 Fixed miscellaneous HURD compilation issues with header file being
4500 included in the right order.
4502 Fixed debugfs so that it resets optind to zero, not one, since setting
4503 optind to zero is more correct.
4506 E2fsprogs 1.04 (May 16, 1996)
4507 =============================
4509 First "official" (1.03 was a limited release only) to support building
4510 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4513 This package includes a RPM specs file, that it can be built using the
4514 RedHat Package Manager.
4516 E2fsck now prints a hint that if there are lots of incorrectly located
4517 inode bitmaps, block bitmaps, and inode table blocks, the user might
4518 want to try using e2fsck -b 8193 first, to see if that fares any
4521 For ext2 filesystem written with the hurd, debugfs will now print out
4522 the translator field when printing an inode structure.
4524 Lots of miscellaneous linking/installation cleanups:
4526 Libraries are now linked using a relative pathname, instead of
4527 relying on -L working correct. It doesn't, in many cases, including
4528 current versions of GNU ld. This guarantees that the build tree is
4529 linking with the right libraries, instead of the ones installed in
4532 Header files, man pages, and the et/ss shell scripts are now
4533 generated using a custom substitution script, instead of relying on
4534 the configure script. This prevents needless recompilation of
4535 files; in addition, the custom substitution script is much faster.
4537 e2fsck may now be linked dynamically, by using the
4538 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4539 since it increases e2fsck's dependence on other files, but some
4540 people need to save disk space, and other critical programs on their
4541 systems were being linked dynamically anyway.
4543 Programs such as fsck which didn't need to be linked against
4544 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4545 only link against libraries they actually need. Otherwise, those
4546 programs would require the presense of libraries that otherwise
4547 could be removed from a rescuse diskette.
4549 The ss include files are now installed correctly so they can
4550 actually be used by another package.
4552 If the profiling libraries are built, they are now installed on a
4553 "make install-libs".
4556 E2fsprogs 1.03 (March 27, 1996)
4557 ===============================
4559 Change the m68k bit numbering for bitmasks to match the bit numbering
4560 used by all other ext2 implementations. (This change was requested by
4561 the m68k kernel development team.)
4563 Support (in-development) filesystem format revision which supports
4564 (among other things) dynamically sized inodes.
4566 Fixed a bug in the ext2 library so that an intelligent error is
4567 returned if mke2fs is run with a ridiculously small number of blocks
4570 Fixed a bug in the ext2 library which required that the device be
4571 openable in read/write mode in order to determine its size. This
4572 caused e2fsck -n to require read/write access when it was not
4573 previously necessary.
4575 Fixed a bug in e2fsck which casued it to occasionally fail the test
4576 suite depending on which version of the floating point library it was
4579 Fixed a bug in e2fsck so that it now halts with a fatal error when
4580 certain superblock consistency checks fail. Previously it continued
4581 running e2fsck, with some potential confusing/damaging consequences.
4583 Added new flag to fsck which allows the root to be checked in parallel
4584 with other filesytems. This is not the safest thing in the world to
4585 do, but some system administrators really wanted it.
4587 Fixed -Wall flames in lib/ss.
4590 E2fsprogs 1.02 (January 16, 1996)
4591 =================================
4593 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4595 Change e2fsck to print statistics of how many non-contiguous files are
4596 on the system. Note that a file which is larger than 8k blocks, it is
4597 guaranteed to be non-contiguous.
4599 In mke2fs, print a warning message if a user tries to format a whole
4600 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
4601 whole disk, the -F (force) option forces mke2fs to format a whole disk
4604 Fix a bug in fsck where in some cases it might start checking
4605 partitions in the next pass before it finishes checking partitions in
4606 the current pass. This still won't cause two partitions on the same
4607 disk will be checked, so it's rarely a problem in real life.
4609 Patch lsattr so that it won't hang when checking a named pipe.
4611 Minor compilation fixes:
4612 * Fix the order of libraries that were linked in debugfs.
4613 * Allow the sources to be compiled with -ansi turned on.
