1 E2fsprogs 1.40.11 (June 17, 2008)
2 =================================
4 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
5 percentage of reserved blocks. (Addresses Debian Bug: #452639)
7 Updated Spanish and Catalan translations.
9 Fixed various Debian packaging issues --- see debian/changelog for
10 details. (Addresses Debian Bugs: #483962, #483023)
12 Add detection for ZFS volumes to the libblkid library.
14 Fixed spelling mistakes, typos, and otherwise clarified man pages.
15 (Addresses Debian Bug: #486463)
20 Fix marginal C code in probe_lvm2() function to the blkid library more
21 portable for older compilers.
23 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
25 Fix ext2fs_swap{16,32,64} functions so they can be used by external
26 applications on big-endian machines. (Addresses Debian Bug: #484879)
29 E2fsprogs 1.40.10 (May 21, 2008)
30 ================================
32 When deciding whether or not to revalidate a blkid cache entry, if the
33 device's mtime is newer than the last time the cached entry was
34 validated, force a revalidation.
36 Fix a potential data corruption bug in e2fsck in the journal replay.
37 The chances of this is happening is extremely remote, especially the
38 default data=ordered or data=writeback modes. However, if a block
39 which has been journalled starts with the first four bytes 0xc03b3998,
40 when e2fsck replays the journal, those four bytes will be replaced
41 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
42 metadata to begin with those fatal 4 byte sequence, and unless
43 data=ordered mode is in use, data blocks are never journaled.
45 Updated German, Dutch, Sweedish, and Vietnamese translations.
50 Fixed various Debian packaging issues --- see debian/changelog for
53 Remove default sizes of types when cross compiling, since autoconf
54 2.50 can figure this out automatically now.
57 E2fsprogs 1.40.9 (April 27, 2008)
58 =================================
60 SuSE's security team audited uuidd and came up with a few minor
61 issues. None of them are serious given that uuidd runs setuid as a
62 unprivileged user which has no special access other than libuuid
63 directory, but it's good to get them fixed.
65 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
66 work correctly with in-inode extended attributes.
68 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
71 Debugfs will avoid using a pager if the standard output is not a tty.
73 Fix debugfs and tune2fs to correctly handle daylight savings time when
74 parsing a time string.
76 Fixed spelling mistakes, typos, and otherwise clarified man pages.
78 Fix fsck completion bars when multiple filesystems were being checked
79 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
80 #203323, Addresses Sourceforge Bug: #1926023)
82 Fix fsck so that progress information is sent back correctly when
83 multiple filesystems are being check and the output of fsck is being
84 redirected to a file descriptor. Also, include the device name (w/o
85 spaces) in the progress information sent back via a file descriptor.
86 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
89 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
91 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
92 signal to its child process.
94 Fix mke2fs's creation of are resize inode when there is a non-standard
95 s_first_data_block setting.
97 Fix bug in blkid when run by an unprivileged user; most devices were
98 not reported correctly. 9Addresses Launchpad Bug: #220275)
100 Mke2fs will not allow the logically incorect combination of
101 resize_inode and meta_bg, which had previously caused mke2fs to create
104 Fix fsck in German locales so that a 'j' means yes.
105 (Addresses Sourceforge Bug: #1947683)
111 Fixed various Debian packaging issues --- see debian/changelog for
114 Update valgrind options in test_script to work with valgrind 3.2.3
116 Update texinfo.tex to a much newer version from the FSF.
118 Remove bashism for configure script and from the lib/ss Makefile.
119 Addresses Sourceforge Bug: 1921969
121 Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
123 Fix build system so that if texinfo is not installed, it won't print a
124 (harmless) error message.
127 E2fsprogs 1.40.8 (March 13, 2008)
128 =================================
130 Fixed e2image -I so it works on image files which are larger than 2GB.
132 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
133 the size is larger than the number of blocks found in the inode, don't
134 try to allocate extra empty blocks at the end of the directory to make
135 up the difference; there's no point to doing that. In addition, if
136 the size is not a multiple of a blocksize, always fix it.
138 E2fsck handled a pass 2 "should never happen error" by not giving
139 enough information and then core dumping. Unfortunately, it was all
140 too easy to trigger the "should never happen" situation if a
141 directory's inode size was not correct. This has been fixed, but
142 e2fsck has also been taught how to handle this situation more
143 gracefully, by simply removing the inode hash tree information, so
144 that it can be rebuilt again after e2fsck's pass 3. (Addresses
145 Launchpad Bug: #129395)
147 Resize2fs had a bug resizing large inodes with extended attributes
148 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
149 completely on big-endian systems such as PowerPC. The bug should be
150 completely fixed now. Yay for regression test suites. (Addresses Red
151 Hat Bugzilla: #434893)
153 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
154 translations. Many thanks to Philipp Thomas from Novell for stepping
155 up to become the new German translation maintainer! (Addresses Debian
156 Bugs: #302512, #370247, #401092, #412882).
158 When e2fsck is clearing a corrupt inode's HTREE directory information,
159 make it clear that it is just clearing the HTREE information, not the
162 Fixed spelling mistakes, typos, and otherwise clarified man pages.
167 Add new functions, ext2fs_dblist_get_last() and
168 ext2fs_dblist_drop_last(), which allows the caller to examine the last
169 directory block entry added to the list, and to drop if it necessary.
171 Fixed a portability problem in libblkid with DJGPP.
173 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
174 to Philipp Thomas for pointing this out.
176 If the info files are not built, change "make install" so it doesn't
177 fail with an error code.
180 E2fsprogs 1.40.7 (February 28, 2008)
181 ====================================
183 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
184 depreciate the -s option, since it can result in filesystems which
185 e2fsck can't fix easily. There are very good reasons for wanting to
186 disable sparse_super; users who wants to turn off sparse_super can use
187 debugfs. (Addresses Sourceforge Bug: #1840286)
189 Add missing options to mke2fs's usage message. (Addresses Sourceforge
192 Fix bug in resize2fs when large (greater than 128 byte) inodes are
193 moved when a filesystem is shrunk; it was only moving the first 128
194 bytes, so extended attributes were not getting moved. (Addresses Red
195 Hat Bugzilla: #434893)
197 E2fsck now prints an explicit message when the bad block inode is
198 updated, to avoid confusion about why the filesystem was modified.
199 (Addresses Sourceforge Bug: #756460)
201 Allow mke2fs and tune2fs manipulate the large_file feature.
202 Previously we just let the kernel and e2fsck do this automatically,
203 but e2fsck will no longer automatically clear the large_file feature.
204 It still isn't really necessary to worry about this feature flag
205 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
208 Suppress message about an old-style fstab if the fstab file is empty.
209 (Addresses Debian Bug: #468176)
211 Fix (really minor) bug in debugfs's find_free_block so it avoids
212 reporting a free block more than once if there are too few free blocks
213 in the filesystem. (Addresses Sourceforge Bug: #1096315)
215 Change e2fsck to no longer clear the LARGE_FILES feature flag
216 automatically, when there are no more > 2GB files in the filesystem.
217 It's been almost a decade since there have been kernels that don't
218 support this flag, and e2fsck clears it quietly without telling the
219 user why the filesystem has been changed.
221 Fix bug which could cause libblkid to seg fault if a device mapper
222 volume disappears while it is being probed. (Addresses RedHat
225 Inhance e2fsck's reporting of unsupported filesystem feature flags.
226 (Addresses Sourceforge Feature Request: #1175808)
228 Fix option syntax in dumpe2fs for explicit superblock and blocksize
229 parameters. What was currently documented in the man page has been
230 broken for some time, due to getopt() implementation changes. The
231 option sytax has been changed to one which is can be more portable
232 supported and which is consistent with the format for extended options
233 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
235 Add support to tune2fs to clear the resize_inode feature. This
236 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
238 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
241 Add support for setting RAID stride and stripe-width via mke2fs and
242 tune2fs. Teach dumpe2fs to print the RAID parameters.
244 Add support for setting new superblock fields to debugfs's
247 Add support for printing "mostly-printable" extended attributes in
250 Add support for the -M option to fsck, which causes it to ignore
253 Fix uuidd so that it creates the pid file with the correct pid number.
254 (Addresses Sourceforge Bug: #1893244)
256 Fix various gcc -Wall warnings.
258 Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
260 Fixed spelling mistakes, typos, and otherwise clarified man pages.
261 (Addresses Sourceforge Patch: #1399325)
267 Fixed various Debian packaging issues --- see debian/changelog for
268 details. (Addresses Debian Bug: #466929)
270 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
271 partially filled-in filesystem object on an error, so that e2fsck can
272 print more intelligent error messages.
274 Add a new function e2p_edit_feature2() which allows the caller to
275 specify which feature flags are OK to set or clear, and which returns
276 more specific information about feature flags which are not allowed to
279 Set the C locale in the test_script driver since it uses [A-Za-z].
280 (Addresses Sourceforge Bug: #1890526)
282 Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
285 Change configure.in to avoid using the 'dc' command unless it is
286 absolutely needed. (i.e., when using parsing a WIP-style version
287 number) (Addresses Sourceforge Bug: #1893024)
289 Add portability checks to support compilation under DJGPP.
291 Update to the latest samba tdb code before the LGPLv3 change, which
292 fixes a realloc() leak on failure.
294 Fix memory leak in ext2fs_alloc_block().
296 Fix makefile dependency issues for various install targets.
297 (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
299 Improve descriptions for the r_move_itable and r_resize_inode tests.
302 E2fsprogs 1.40.6 (February 9, 2008)
303 ===================================
305 Add support for returning labels for UDF filesystems in the blkid
308 Fix bug in the blkid library where cached filesystems was not being
309 flushed when opening USB devices returned the error ENOMEDIUM.
310 (Addresses Debian Bug: #463787)
312 Added logic to the blkid library to automatically choose whether a
313 filesystem should be mounted as ext4 or ext4dev, as appropriate.
315 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
317 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
318 configured with --enable-jbd-debug.
320 Document the BLKID_FILE environment variable in the libblkid man page
325 Update e2fsprogs translation template and Vietnamese and Czech translations
327 Fixed various Debian packaging issues --- see debian/changelog for
328 details. (Addresses Debian Bugs: #436058)
330 Don't try to create $DESTDIR/etc/init.d as part of make install as we
331 don't install the init.d script (and it's not the recommended way to
332 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
334 Use thread local storage to fix a theoretical race condition if two
335 threads try to format an unknown error code at the same time in the
339 E2fsprogs 1.40.5 (January 27, 2008)
340 ===================================
342 Fix a potential overflow big in e2image if the device name is too
345 Mke2fs will now create new filesystems with 256 byte inodes and the
346 ext_attr feature flag by default. This allows for much better future
347 compatibity with ext4 and speeds up extended attributes even on ext3
350 Teach e2fsck to ignore certain "safe" filesystem features which are
351 set automatically by the kernel. Having the kernel set features
352 automagically behind the user's back is a bad idea, and we should try
353 to break the kernel of this habit, especially for the newer ext4
354 feature flags. But for now, we will try to avoid needless full checks
355 which can annoy users who are doing fresh installs.
357 Add support in tune2fs and mke2fs for making a filesystem as being "ok
358 to be used with test kernel code". This will be needed for using test
359 filesystems with the latest ext4 kernel code.
361 Change e2fsck -fD so that it sorts non-htree directories by inode
362 numbers instead of by name, since that optimizes performances much
363 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
365 If e2image fills the disk, fix it so it exits right away instead of
366 spewing large numbers of error messages.
367 (Addresses-Sourceforge-Feature-Request: #606508)
369 If ftruncate64() is not available for resize2fs, let it use ftrucate()
370 instead, but have it check to see if the size would get truncated, and
371 skip calling ftruncate in that case.
373 Add support for detecting HFS+ filesystems in the blkid library.
375 Add supprt in the blkid library for ext4/ext4dev filesystems.
377 Fix a bug in blkid where it could die on a floating point exception
378 when presented with a corrupt reiserfs image.
380 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
381 such that UUID string is a fixed length.
383 Add sample python bindings for the uuid library to the contrib
384 directory. (Addresses-Sourceforge-Patches: #778817)
386 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
387 will work with large files. (Addresses Sourceforge Feature Request:
388 #1257500 and Sourceforge Support Request: #1253511)
390 Allow the debugfs 'undel' command to undelete an inode without linking
391 it to a specific destination directory, since this might require
392 allocating blocks that could overwrite some yet-to-be-recovered
393 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
395 Update Swedish translations from the Translation Project.
400 Fix configure handling of --sbindir (which should rarely be used, but
401 someone did complain, so let's fix it). (Addresses Sourceforge Bug:
404 Updated e2fsprogs.spec file to include a new uuidd package
406 Use pkg-config to determine where to find the devmapper library so we
407 can find out where it is located on different distributions.
409 Fix Makefile race so that "make -j3 distclean" works correctly
411 Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
412 especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
415 Fixed spelling mistakes, typos, and otherwise clarified man pages.
417 Fixed various Debian packaging issues --- see debian/changelog for
418 details. (Addresses Debian Bugs: #459403, #459475, #459614)
420 Remove the --enable-dynamic-static configure option, and build e2fsck
421 dynamically by default. If the user wants e2fsck.static, he/she will
422 need to build it via "make -C e2fsck e2fsck.static"
424 Fix various build warnings due to missing prototypes.
425 (Addresses Sourceforge Patch: #1861663, #1861659)
428 E2fsprogs 1.40.4 (December 31, 2007)
429 ====================================
431 Improve time-based UUID generation. A new daemon uuidd, is started
432 automatically by libuuid if necessary. This daemon is setuid to allow
433 updates to /var/lib/libuuid, so the clock sequence number can be
434 stored and so if the clock is set backwards, it can be detected.
435 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
438 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
439 superblocks. This avoids e2fsck from concluding that a full
440 filesystem check is required before backing up the superblock due to
441 changes in the feature flags. (Addresses Debian Bug: #454926)
443 Fix fsck to only treat the '#' character as a comment at the beginning
444 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
445 will cause fsck to issue an bogus warning message.
446 (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
448 Format control characters and characters with the high eighth bit set
449 when printing the contents of the blkid cache, to prevent filesystems
450 with garbage labels from sending escape sequences to the user's screen
451 that might, for example place it in graphics mode. (Addresses Ubuntu
454 Fix sign-extension problem on 64-bit systems in in the com_err
455 library. (Addresses Sourceforge Bug: #1809658)
457 Avoid division by zero error when probing an invalid FAT filesystem in
458 the blkid library. (Addresses Sourceforge Bug: #1831627)
460 Update Dutch, Polish, and Vietnamese translations from the Translation
461 Project. Remove the Rwandan translation upon advice of the
467 Fix the libss "make check" regression test so that it works if the
468 current directory is not in the user's path or if the libss shared
469 library is not installed. (Addresses Sourceforge Bug: #1848974)
471 Fixed spelling mistakes, typos, and otherwise clarified man pages.
472 (Addresses Debian Bugs: #444883, #441872)
474 Fixed various Debian packaging issues --- see debian/changelog for
475 details. (Addresses Debian Bugs: #437720, #451172, #458017)
477 Fix build failure on non-Linux/non-Hurd/non-Masix systems.
478 (Addresses Sourceforge Bug: #1859778)
480 Fix Hurd portability issues. (Addresses Debian Bug: #437720)
483 E2fsprogs 1.40.3 (December 5, 2007)
484 ===================================
486 Fix a potential security vulnerability where an untrusted filesystem
487 can be corrupted in such a way that a program using libext2fs will
488 allocate a buffer which is far too small. This can lead to either a
489 crash or potentially a heap-based buffer overflow crash. No known
490 exploits exist, but main concern is where an untrusted user who
491 possesses privileged access in a guest Xen environment could corrupt a
492 filesystem which is then accessed by the pygrub program, running as
493 root in the dom0 host environment, thus allowing the untrusted user to
494 gain privileged access in the host OS. Thanks to the McAfee AVERT
495 Research group for reporting this issue. (Addresses CVE-2007-5497.)
497 Fix hueristics in blkid which could cause a disk without partitions to
498 be incorrectly skipped when a loopback device is present. (Addresses
499 Red Hat Bugzilla #400321.)
501 Fix e2image so that in raw mode it does not create an image file which
502 is one byte too large.
504 Change mke2fs's usage message so it recommends the preferred -E option
505 instead of the deprecated -R option.
507 Enhance the blkid library so it will recognize squashfs filesystems.
508 (Addresses Red Hat Bugzilla #305151.)
510 Enhance e2fsck so it will force the backup superblocks to be backed up
511 if the filesystem is consistent and key constants have been changed
512 (i.e., by an on-line resize) or by e2fsck in the course of its
515 Enhance blkid's detection of FAT filesystems; so that USB disks with
516 only a single bootable partition will not get missed.
518 E2fsck will no longer mark a filesystem as invalid if it has time
519 errors (i.e., if superblock mount time or last write time is in the
520 future) and the user refuses to fix the problem.
522 The Ubuntu init scripts don't properly set the system time correctly
523 from hardware clock if the hardware clock is configured to tick local
524 time instead of GMT time. Work around this as best as we can by
525 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
526 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
529 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
530 Hat Bugzilla #151533.)
532 Fix e2fsck so that if the superblock is corrupt, but still looks
533 vaguely like an ext2/3/4 superblock, that it automatically tries to
534 fall back to the backup superblock, instead of failing with a hard
537 Make the e2fsprogs program more robust so that they will not crash
538 when opening a corrupt filesystem where s_inode_size is zero.
540 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
541 arguments are detected as such and the parse error is reported to the
542 user. (Addresses Debian Bug #435381.)
544 Change e2fsck so it will not complain if a file has blocks reallocated
545 up to the next multiple of a system's page size.
547 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
548 about (valid) filesystems where the inode table extends to the last
549 block of the block group. (Addresses Red Hat Bugzilla #214765.)
551 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
552 allocating inode tables for some relatively rare odd disk sizes.
553 (Addresses Red Hat Bugzilla #241767.)
555 Add Catalan translation and update Dutch and Swedish translations
556 from the Translation Project.
558 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
559 still had an issue when trying to figure out whether we need to
560 byte-swap fast symlinks that contained extended attributes.
562 Fixed spelling mistakes, typos, and otherwise clarified man pages.
563 (Addresses SourceForge Bug #1821333.)
569 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
571 Add "make check" to the RPM spec file
573 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
574 works correctly when the prefix is not the root directory.
576 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
577 clena up after themselves by deleting the test.img temporary file
578 after completing the test.
580 Fixed a corner case bug ext2fs_unlink() when trying to delete the
581 first directory entry in a directory block and the last directory
582 entry in the previous directory block is not in use. Fortunately
583 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
584 places where it is extremely unlikely to run into this corner case.
586 Fix missing dependency which would cuase parallel builds to fail.
587 (Addresses Sourceforge Bug #1842331.)
589 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
590 calling open(O_CREATE) with a missing mode parameter.
592 Fix the test_ss.c in lib/ss so it can be used as an example
593 application program for the library as well as a regression test
596 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
597 are properly passed back up through the call stack.
599 E2fsprogs 1.40.2 (July 12, 2007)
600 ================================
602 A recent change to e2fsck_add_dir_info() to use tdb files to check
603 filesystems with a very large number of filesystems had a typo which
604 caused us to resize the wrong data structure. This would cause a
605 array overrun leading to malloc pointer corruptions and segfaults.
606 Since we normally can very accurately predict how big the the dirinfo
607 array needs to be, this bug only got triggered on very badly corrupted
610 Fix a bug in e2fsck which caused it to incorrectly salvange
611 directories when the last entry's rec_len is bogusly too big. This
612 resulted in a nonsense filesystem corruption to be reported, and
613 required a second run of e2fsck to fully fix up the directory.
615 Update tune2fs man page to include more discussion of reserved blocks
616 (Addresses Launchpad bug #47817)
618 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
622 E2fsprogs 1.40.1 (July 7, 2007)
623 ===============================
625 Fix bug which could cause libblkid to loop forever. When revalidating
626 a partition where there is obsolete information in /etc/blkid.tab, we
627 end up freeing a the type tag without clearing dev->bid_type, causing
628 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
630 The Turkish translation has a bug in it where it has the translation
631 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
632 @E, recursively, forever, until the stack fills up and e2fsck core
633 dumps. We fix this by making e2fsck stop @-expansions after a
634 recursive depth of 10, which is far more than we need.
635 (Addresses Sourceforge Bug: #1646081)
637 Compile the default mke2fs.conf into mke2fs program. People are
638 getting surprised by mke2fs creating filesystems with different
639 defaults than earlier versions of mke2fs if mke2fs.conf is not
640 present. So we now create a built in version of mke2fs.conf file
641 which is used by mke2fs if the /etc/mke2fs.conf is not present.
642 (Addresses SourceforgeBug: #1745818)
644 Improve the config/parse_types.sh helper script. Fix a potential
645 security problem if e2fsprogs is built as root (as Gentoo does!). In
646 addition fix the script and how it is called from the configure script
647 so that it does the right thing when cross-compiling. (Fixes Gentoo
650 Update Vietnamese, French, and Dutch PO files from the Translation
651 Project. Also created a new e2fsprogs.pot file for translator.
653 Fix bogus strip permission errors when building under Debian. When
654 building the e2fsprogs dpkg's, the dh_strip command emits a large
655 number of error messages caused by the permissions not being right.
656 So run dh_fixperms before running dh_strip.
661 Add new function: profile_set_default(). This function sets the value
662 of the pseudo file "<default>". If the file "<default>" had
663 previously been passed to profile_init(), then def_string parameter
664 will be parsed and used as the profile information for the "<default>"
667 Fix mk_cmds's error reporting so that it is unambiguous that it is the
668 mk_cmds script which is generating the error. (Obviates Gentoo patch:
669 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
671 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
672 priority" environment variable that overrides all others, where as
673 LANG is the lowest priorty environment variable. If LC_ALL is set, it
674 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
675 the all the rest are set. This will assure that the locale when
676 running the test suites is the "C" locale. (Obviates Gentoo patch:
677 e2fsprogs-1.38-tests-locale.patch)
680 E2fsprogs 1.40 (June 29, 2007)
681 ==============================
683 Fix divide by zero error in blkid's NTFS probing logic.
685 Add new blkid -g option which causes the blkid cache to be garbage
688 Fix a bug in libblkid which could cause the internal field bid_type to
689 become corrupted. Fortunately bid_type isn't used much, and bid_label
690 and bid_uuid is only used by debugging code, so the impact of this bug
693 Mke2fs will now store the RAID stride value when a filesystem is
694 created with a requested RAID stride, and then use it automatically in
697 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
698 isn't too big. In some cases Lustre users have tried specifying an
699 inode size of 4096 bytes, while keeping an inode ratio of one inode
702 Improve sanity check in e2fsck's algorithm for finding a backup
703 superblock, so that it won't accidentally find a superblock that was
704 located in the journal, and then later reject it as being not a valid
707 Fix e2fsck get_size logic so that it will work with the Linux floppy
708 driver. The Linux floppy driver is a bit different from the other
709 block device drivers, in that if the device has been opened with
710 O_EXCL, it disallows another open(), even if the second open() does
711 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
713 Fix error checking of badblock's last-block and start-block arguments.
714 (Addresses Debian Bug: #416477)
716 Fix e2fsck so that it doesn't overwrite the backup superblocks when
717 recovering a journal until the master superblock has been confirmed as
720 Change the blkid library to be much more paranoid about concluding
721 that a partition contains an NTFS filesystem, and fetch the UUID and
722 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
725 Factor out the code which sets the default journal size and move it
728 Enhance e2fsck so it will recreate the ext3 journal if the original
729 journal inode was cleared to due it being corrupt after finishing the
732 Fix e2fsck so that it updates the journal inode if it is corrupted and
733 the backup journal information from the superblock was successfully
734 used to recover the filesystem.
736 Fix e2fsck so that it checks all of the blocks in the journal inode
737 for validity. The original code only checked the direct blocks to
738 make sure the journal inode was sane. Unfortunately, if some or all
739 of the indirect or doubly indirect blocks were corrupted, this would
742 Add support in blkid to detect LUKS encrypted partitions.
744 Add extra sanity checks for extended attributes in the case where the
745 size is zero but the offset is very large.
747 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
748 and ext2fs_get_next_inode_full().
750 Clarify the copyright licenses used by the various libraries in
751 the top-level COPYING file (Red Hat Bugzilla: 166058)
753 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
755 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
757 Remove check in e2fsck which requires EA's in inodes to be sorted;
758 they don't need to be sorted, and e2fsck was previously wrongly
759 clearing unsorted EA's stored in the inode structure.
761 Allow mke2fs or tune2fs to create a substantially larger journal (up
762 to 10,240,000 blocks).
764 Fix MD superblock detection, and make sure the correct UUID is
765 reported from the MD superblock.
767 Fix a signed vs. unsigned bug in debugfs.
769 Enhance debugfs's date parser so that it accepts integer values.
771 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
772 file with multiply claimed blocks is hard linked. or not at all if the
773 root directory contains shared blocks
775 Enhance debugfs so it can modify the block group descriptors using the
776 command set_block_group_descriptor.
778 Improve e2fsck's reporting of I/O errors so it's clearer what it was
779 trying to do when an error happens
781 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
782 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
783 #232663 and LTC Bugzilla: #27634)
785 Fix potential file descriptor leak in ext2fs_get_device_size() in an
788 Add libreadline.so.5 support to libss.
790 Impove badblocks -n/-w exclusive usage message.
792 Fix dump_unused segfault in debugfs when a filesystem is not open
794 Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
796 Allow the debugfs lcd command to work w/o a filesystem being open.
797 (Addresses LTC Bugzilla #27513)
799 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
800 field on the first pass.
802 Fix e2fsck to set the file type of the '..' entry when connecting
803 a directory to lost+found. (Addresses Lustre Bug: #11645)
805 Enhance e2fsck to recover directories whose modes field were corrupted
806 to look like special files. This is probably only useful in
807 artificial test cases, but it will be useful if we ever do the "inodes
808 in directory" idea for ext4.
810 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
813 Fix resize2fs parsing of size parameter (in sector units). This was
814 actually a bug in libe2p's parse_num_blocks() function. When handling
815 the 's' suffix, it was ignoring the blocksize information passed in
816 from the caller and always interpreting the number in terms of a 1k
817 blocksize. (Addresses Debian Bug: #408298)
819 There was a floating point precision error which could cause e2fsck to
820 loop forever on really big filesystems with a large inode count.
821 (Addresses Debian Bug: #411838)
823 Fix memory leak in ext2fs_write_new_inode()
825 Add support for using a scratch files directory to reduce e2fsck's
826 emory utilization on really big filesystems. This uses the TDB
827 library. See the [scratch_files] section of the e2fsck.conf man page
830 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
831 platform (Addresses Debian Bug: #397044)
833 Add explanatory message to badblocks that -n and -w are mutually exclusive
834 (Addresses Debian Bug: #371869)
836 Allow debugfs and dumpe2fs to support fs features under development.
838 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
839 ext2fs_open() , which allows application to open filesystes with features
840 which are currently only partially supported by e2fsprogs.
842 Allow unix_io to support offsets greater than 2G (Addresses
843 SourceForge Bug: #1547922)
845 Fixed overflow and signed/unsigned problems caused by the number of
846 blocks or inodes exceeding 2**31 or being close to 2**32-1.
848 Add support for unsigned directory hash calculations with hints in the
849 superblock to fix cross-architectural portability for htree
850 directories with filenames where the high 8th bit is set. (Addresses
853 Fix resize2fs so that it gives user-intelligible error messages if the
854 filesystem or the kernel does not support on-line resizing.
855 (Addresses Debian Bug: #380548)
857 Require mke2fs -F -F for really dangerous operations, since -F is
858 needed for less dangerous operations such as creating filesystems
859 images in regular files, or creating filesystems on whole block
860 devices. These relatively innocuous usages should NOT be confused
861 with running mke2fs on an apparently-mounted or in-use filesystem.
863 Allow the default inode size to be specified into the mke2fs.conf
866 Make the smallest default journal size is big enough so that on-line
867 resizing should always work.
869 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
872 Fix debugfs coredump when lsdel is run without an open filesystem
873 (Addresses Debian Bug: #378335)
875 Fix debugfs display bug us that bytes that have the high bit set are
876 displayed as "ec" instead of "ffffffec".
878 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
880 Device mapper scanning wasn't working in the blkid library because the
881 pathnames had an extra "/dev" when they were being probed.
883 Add GFS/GFS2 support to the blkid library.
885 Fix blkid support of empty FAT filesystem labels.
887 Avoid recursing forever (or for a long time) when the blkid library
888 searches for a device and there are symlinks to directories in /dev.
890 Avoid unaligned halfword access in blkid when accessing FAT
891 superblocks, as this will cause Sparc/Solaris systems to throw a
894 The latest devmapper libraries requires pthreads, add -lpthreads to
895 the static link libraries for e2fsck.static if devmapper is enabled.
896 (Addresses Debian bug: #388718)
898 Improve the (non-installed, for experts only) findsuper program by
899 printing the uuid and label from the superblocks, as well as the
900 starting and ending offsets of the filesystem given the information in
901 the superblock. Omit by default printing superblocks that are likely
902 found in located in an ext3 journal unless an explicit -j option is
905 Updated Spanish, French and Dutch translations and added Catalan
906 translation. (Addresses Debian bug: #411562)
908 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
909 determining a partition's size, since binary searching to determine
910 the device doesn't work on FreeBSD.
912 Documentation about UUID's is available in enough places, and it's
913 awkward to deal with debian-legal's insanities. So I'm caving in the
914 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
915 don't have do the dfsg tarball. Also remove the rule that only tried
916 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
917 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
919 Fix the info-dir line so that the menu name does not contain a .info
920 prefix. First of all, it's ugly, secondly, it causes the install-info
921 command to fail to remove the com_err info file from the
922 /usr/share/info/dir file when the comerr-dev package is removed and
923 purged. (Addresses Debian Bug: #401711)
925 Fixed spelling mistakes, typos, and otherwise clarified man pages.
926 (Addresses Debian Bug: #369761, #373004, #379695)
928 Fixed various Debian packaging issues --- see debian/changelog for
929 details. (Addresses Debian Bugs #389554, #390664, #413208, #419605,
930 #408352, #415560, #399155)
936 E2fsck now supports the %It expansion when printing a problem report.
937 It will print the type of the inode in the problem context.
939 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
940 (Addresses Sourceforge Bug: #1565561)
942 Remove unused variables and other lint/gcc -Wall cleanups
944 Add check to ext2fs_get_device_size() so it will return EFBIG for for
945 filesystems contained in regular files where the filesystem image size
946 is returned by stat64().
948 Set local environment variables to C so mk_cmds and compile_et always
949 work. (Addresses SourceForge Bug: #1532177)
951 Added the 64-bit byte swapping function ext2fs_swab64().
953 Added two new helper functions to prevent 2**31/2**32-1 overflow
954 problems: ext2fs_div_ceil() and e2p_percent().
956 Create new ext2fs library inline functions ext2fs_group_first_block()
957 and ext2fs_group_last_block() in order to calculate the starting and
958 ending blocks in a block group.
960 Create the generated files read-only to remind developers not to edit them.
962 Add support for autoconf 2.60 (with backwards compatibility for older
963 versions of autoconf).
965 Added an "make rpm" target to top-level Makefile
967 Added various FreeBSD portability fixes.
969 Exclude mercurial files from the RPM build tree to speed up copy/build.
971 Use root_sysconfdir to define the locations of mke2fs.conf and
972 e2fsck.conf instead of using a hard-coded /etc pathname.
974 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
976 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
978 If diff -u is supported, use it to report test failures.
980 Updates/improvements to RPM spec file
982 Add on-disk format definitions for the following new features:
983 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
984 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
985 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
987 Add a new make target "checked-failed" in the tests directory which
988 reruns any failed tests
990 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
992 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
993 pointer dereferences, memory leaks, etc. None were security-criticial
996 Fix up usage and decrement error messages in the test_icount program
998 Add debugging code to the com_err library; if the environment variable
999 COMERR_DEBUG is set to 1, print out debugging messages as error tables
1000 are added and removed from the com_err library. If the
1001 COMERR_DEBUG_FILE environment variable is set (and the process is not
1002 setuid) the debugging messages may be redirected to a file.
1004 Change all of the e2fsprogs programs to use the newer add_error_table()
1005 and remove_error_table() interfaces instead of the much older
1006 initialize_*_error_table() function.
1008 Add TDB support into the ext2fs library. This allows us to have a
1009 guaranteed library we can count on always being present so we can
1010 store data in an on-disk database.
1012 Add support for using TDB to store the icount data, so we don't run out
1013 of memory when checking really large filesystems.
1015 Change the regression test suite so that it skips empty test directories.
1017 Define the l_i_iversion field in ext2_inode. The l_i_version field is
1018 now defined from the old l_i_reserved1 field in the ext2 inode. This
1019 field will be used to store high 32 bits of the 64-bit inode version
1022 Add Makefile production rule for e2fsprogs.spec in case it gets
1025 Add new function profile_get_uint() to allow for a clean way to fetch
1026 unsigned integers from the context.
1028 Add test to make sure the ext2 superblock structure is 1024 bytes.
1030 Fix typo in name of f_dup4 regression test
1032 Add new function blkid_gc_cache() which performs a garbage collection
1033 pass on the /etc/blkid.tab file.
1035 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
1036 general, only e2fsck (after the filesystem is clean), tune2fs, and
1037 resize2fs should change the backup superblocks by default. Most
1038 callers of ext2fs_open() should not be touching any superblock fields
1039 which require the backups to be touched.
1041 Add new function to libext2fs, ext2fs_default_journal_size(), which
1042 returns the default journal size.
1045 E2fsprogs 1.39 (May 29, 2006)
1046 =============================
1048 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
1049 between 2**31 and 2**32 blocks.
1051 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
1052 configure the filesystem features, blocksize, and inode_ratio for
1053 different filesystem types.
1055 Mke2fs will now create filesystems hash trees and on-line resizing
1056 enabled by default, based on the new /etc/mke2fs.conf file.
1058 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
1059 filesystem device node in exclusive mode to prevent accidents by
1060 system administrators. In the case of resize2fs and mke2fs, it will
1061 only use exclusive mode if the filesystem is not mounted.
1063 Fixed a bug in mke2fs which caused it to to fail when creating the
1064 resize inode for large filesystems. (Addresses Debian Bug #346580)
1066 When allocating space for the RAID filesystems with the stride
1067 parameter, mke2fs will now place each portion of the group's inode
1068 table right up after the superblock (if present) in order to minimize
1069 fragmentation of the freespace.
1071 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
1072 efficiently by writing the inode and block bitmaps in one pass, thus
1073 reducing the number of disk seeks required.
1075 Add support for on-line resizing to resize2fs.
1077 Fix blkid library so that logic to determine whether or not a device's
1078 cached information in /etc/blkid.tab needs to be verified or not
1079 doesn't get confused by a system clock which is insane (for example,
1080 if the battery is dead on a Macintosh running PPC Linux. (Addresses
1081 Red Hat Bug: #182188)
1083 The blkid library will now store the UUID of the external journal used
1084 by ext3 filesystems, so that in the future, the userspace mount binary
1085 can use this to find the location of the external journal and pass
1086 this information to the kernel.
1088 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
1089 control how various options should be handled. See the e2fsck.conf
1090 man page for more details. (Addresses Debian Bug: #150295)
1092 E2fsck now prints an explanatory message when delaying a filesystem
1093 check when the system is running on battery. (Addresses Debian Bug:
1096 E2fsck will detect if the superblock's last mount field or last write
1097 field is in the future, and offer to fix if so. (Addresses Debian Bug
1098 #327580) These problems will be fixed automatically in preen mode
1099 since Debian's boot sequence bogusly doesn't set the time correctly
1100 until potentially very late in the bootup process, and this can cause
1101 false positives which will cause users' systems to fail to boot.
1102 (Addresses Debian Bugs #343662 and #343645)
1104 E2fsck now checks to see if the superblock hint for the location of
1105 the external journal is incorrect, and if so, offer to update it.
1106 (Addresses Debian Bug: #355644)
1108 Fix e2fsck from segfaulting on disconnected inodes that contain one or
1109 more extended attributes. (Addresses Debian Bug: #316736, #318463)
1111 E2fsck will stop and print a warning if the user tries running a
1112 read/write badblocks test on a read-only mounted root filesystem.
1114 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
1115 C. Thompson for pointing these out; they were originally found using
1118 When resizing a file containing a filesystem, resize2fs will expand or
1119 truncate a file as necessary. (Addresses Debian Bug: #271607)
1121 Resize2fs will now automatically determine the RAID stride parameter that
1122 had been used to create the filesystem, and use that for newly created
1123 block groups. The RAID stride parameter may also be manually specified
1124 on the command line using the new -S option to resize2fs.
1126 Fix mke2fs so that it correctly creates external journals on
1127 big-endian machines (such as a S/390).
1129 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
1130 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
1131 Chambraud for pointing this out.)
1133 Dumpe2fs will now print the size of the journal (if present).
1135 Fix debugfs's set_inode_field command so it can properly set the frag,
1136 fsize, uid_high, gid_high, and author fields in the inode instead of
1137 silently failing, and so that setting the i_size actually sets i_size
1140 Add a new debugfs command, set_current_time, which sets fs->now so
1141 that regression test suites can repeatedly modify the filesystem's
1144 Fix a bug in debugfs's icheck which would incorrectly report the owner
1145 of an extended attribute block.
1147 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
1148 print a usage message when an illegal option character is given.
1150 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
1151 so it won't core dump. (Addresses SourceForge bug #1424311)
1153 Fix mklost+found so that it creates a full-sized directory on
1154 filesystems with larger block sizes.
1156 Fix a file descriptor leak in blkid library.
1158 Fix a display bug in "badblocks -sv" so that the done message properly
1159 clears the block number at the end of the test. (Addresses Debian Bug
1162 Allow fractional percentages to the -m option in mke2fs and tune2fs

1165 Use fstat/fstat64 in getsize.c if the the target is a regular file,
1166 instead of attempting to do a binary search. Fix some fd leaks in
1169 Add support for device mapper library to the blkid library to ensure
1170 that the "best" (i.e., leaf) device is probed by the blkid library.
1172 Fix the blkid library so that it notices when an ext2 filesystem is
1175 Improve the blkid's library VFAT/FAT detection; it now understands
1176 labels stored in the root directory, and is more paranoid about
1177 checking the FAT superblock values.
1179 Fixed a fd leak in the uuid library which was causing problems for the
1180 LVM tools. (Addresses Debian Bug: #345832)
1182 Add support for the reiser4 and software suspend partitions to the
1183 blkid library. Also add support for extract the label from iso9660
1186 Fix a compile_et bug which miscount the number of error messages if
1187 continuations are used in the .et file.
1189 Add extra sanity checks to protect users from unusual cirucmstances
1190 where /etc/mtab may not be sane, by checking to see if the device is
1191 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
1194 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian

1214 Update config.guess and config.sub to latest version (2006-02-23) from
1217 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
1218 Bugs: #360661, #360317)
1220 Fixed the Makefile so that they work correctly on newer versions of
1221 GNU make (i.e., 3.81).
1223 Add valgrind support to the regression test suites, and eliminate
1224 false positives from valgrind.
1226 Add a regression test suite for the blkid library.
1228 Fix a fencepost error in resize2fs caught by valgrind.
1230 Fix compiler warnings about missing memcpy prototypes.
1232 We no longer have the sparc assembly code in the header file any more,
1233 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
1234 break compiles on the sparc architectures when using gcc.
1236 In the libext2fs library, add the new field fs->now which if non-zero
1237 is used instead of the system time when setting various filesystem
1238 fields (last modified time, last write time, etc.)
1240 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
1241 ext2fs.h which is needed since the inline functions use memcpy().
1242 (Addresses Sourceforge Bug #1251062)
1244 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
1245 the build system when building files in the util directory which are
1246 needed during the build process. This avoids potential problems when
1247 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
1248 are not recognized as valid by the host compiler. (Addresses
1249 Sourceforge Bug #1261547)
1251 Clean up the blkid library by making the superblock and generic i/o
1252 functions to be more generic. Clean up interface to the probe
1253 function, and fix memory leak. Finallly, remove an unneeded reference
1254 to probe.h in the lib/blkid/resolve.c
1256 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
1257 of invalid block #'s.
1259 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
1260 indicate that the the function read/writes the memory location.
1262 Fix various gcc -Wall complaints.
1264 Add a dependency to make sure that the subdirectories are created
1265 before creating all of the object files, in order to address parallel
1266 build problem in the library Makefiles. (Addresses Sourceforge Bug:
1269 Add $(LDFLAGS) to the command line argument when generating an ELF or
1270 Solaris shared library, to allow cross-compile and other builds that
1271 might need to specify -L paths to needed libraries. (Addresses
1272 Sourceforge Bug #1261549)
1274 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
1275 intended for testing purposes. It allows an ext2/ext3 developer to
1276 create very large filesystems using sparse files where most of the
1277 block groups are not initialized and so do not require much disk
1278 space. Eventually it could be used as a way of speeding up mke2fs and
1279 e2fsck for large filesystem, but that would be best done by adding an
1280 RO_COMPAT extension to the filesystem to allow the inode table to be
1281 lazily initialized on a per-block basis, instead of being entirely
1282 initialized or entirely unused on a per-blockgroup basis.
1284 Fix backwards compatibility so e2fsprogs will better compile on Linux
1287 Make test scripts more robust against locale-related environment variables
1289 Fix type warning problem with sizeof() in ext2fs_open2().
1291 Fix type warning problem with time_t in debugfs.
1294 E2fsprogs 1.38 (June 30, 2005)
1295 ==============================
1297 Fix blkid's test programs (built with "make check") compile correctly
1298 even without "configure --enable-blkid-debug".
1300 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
1301 type aliasing rules on newer gcc compilers. (Addresses Red Hat
1304 Fix com_err library to make it more compatible with recent changes
1305 made to the com_err library in MIT Kerberos V5 version 1.4.
1306 (Addresses Sourcefroge Bug #1150146)
1308 General cleanup of messages printed by e2fsprogs programs for grammar,
1309 consistency, and to make life easier for translators. Fixed a few
1310 strings containing English that had not been marked as needing
1311 translations. Removed strings that do not need to be translated, to
1312 make life easier for translators.
1314 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
1315 test to see if a device appears to be in use instead of just relying
1316 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
1318 Fix portability problem in the filefrag program affecting platforms
1319 where the size of an integer is smaller than the size of a long.
1320 (Addresses Debian Bug #309655)
1322 Mke2fs will now use a larger journal by default for filesystems
1323 greater than 4GB. (128 MB instead of 32MB).
1325 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
1326 unless forced. This is to avoid signed vs. unsigned kernel bugs in
1327 block numbers that still need to be fixed.
1329 The blkid program has a new option which will more efficiently search
1330 for device when it is known (or expected) that only one matching
1331 device will be found in the system, such as when doing a lookup by
1334 Debian's e2fsprogs-specific initrd fragment will avoid including
1335 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
1336 and LD_LIBRARY_PATH, and filtering out libraries found in
1337 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
1339 Fixed a potential portability issue in the blkid programs for
1340 architectures where the char type is unsigned. (Addresses Sourceforge
1343 Fix a bug in filefrag so that it doesn't falsely count an extra
1344 discontinuity when the first block found is an indirect block.
1345 (Addresses Debian Bug #307607).
1347 Fix blkid's recognition of cramfs filesystems, and enhance it to be
1348 able to handle cramfs labels.
1350 Fix debugfs's stat command to not core dump when a filesystem is not
1353 Fix e2fsck's handling of error conditions caused by the resize inode
1354 claiming blocks that are also used by other inodes, a filesystem
1355 corruption which was commonly caused by a bug in Fedora Core 3's
1358 Fixed bug in filefrag which caused it to fail on non-ext2/3
1359 filesystems. (Addresses Debian Bug: #303509)
1361 If the superblock last mount time indicates that the system clock may
1362 not be accurate, then e2fsck will omit checking inodes' deletion time
1363 field for indications of a potential corrupted orphaned inode list.
1364 (Previously e2fsck only ommited these LOW_DTIME checks when the
1365 superblock's last write time looked insane.)
1367 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
1368 (Addresses Debian bug #302200)
1370 Make the blkid library more paranoid about being run from setgid
1371 programs, and to use __secure_getenv() from libc if it is available.
1373 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1374 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
1375 and Sourceforge Bug: #1189803)
1377 Updated and fixed translations.
1379 Fixed various Debian packaging issues --- see debian/changelog for
1385 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
1386 changed to take an unsigned int for the bit number. Negative bit
1387 numbers were never allowed (and didn't make any sense), so this should
1388 be a safe change. This is needed to allow safe use of block numbers
1389 greater than or equal to 2**31.
1391 The compile_et program will avoid recreating generated foo_err.c and
1392 foo_err.h files if no changes are necessary. The compile_et program
1393 will also atomically replace these files to avoid a potential parallel
1394 build race problem on SMP systems. (Addresses Sourceforge Bug:
1397 Added a new function to the blkid library, blkid_probe_all_new(),
1398 which only probes newly added disk devices, and change
1399 blkid_find_dev_with_tag() to use this function so that when a
1400 requested tag is not found, devices that were previously not checked
1401 are searched before searching all devices in the system.
1403 Added new functions to the blkid library, blkid_dev_set_search() and
1404 blkid_dev_has_tag().
1406 E2fsck's problem strings can now use @m and @n as abbrevations for
1407 "multiply-claimed" and "invalid", respectively.
1409 The e2fsprog.pot file now has an explanation of how the @-expansion
1410 and %-expansion works, and strings in e2fsck/problem.c which contain @
1411 characters now have comments in e2fsprogs.pot with the @-expansion to
1412 make life easier for translators.
1414 Fixed missing return values in the ext2fs library which could cause it
1415 to return random garbage in certain error conditions.
1417 Allow the current time to be overriden via the E2FSCK_TIME environment
1418 variable for use in regression tests.
1420 The test scrpit driver program now exits with a non-zero status if
1421 there any of its test that it ran failed.
1423 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
1426 Fixed "make check" so that it compiles correctly even when e2fsprogs'
1427 header files have not be installed in the system include directories.
1428 (Addresses Sourceforge Bug: #1180572)
1430 Fixed gcc -Wall nits.
1433 E2fsprogs 1.37 (March 21, 2005)
1434 ===============================
1436 Add support for checking the validity of Extended Attributes stored in
1439 Add support for dumping the contents of large inodes to debugfs,
1440 including the extended attributes stored in inodes.
1442 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1443 when we create a new inode we make sure that the extra information in
1444 the inode (any extra fields in a large inode and any ea-in-inode
1445 information) is initialized correctly. This can take place when
1446 mke2fs creates the root and lost+found directory, when e2fsck creates
1447 a new root inode or a new lost+found directory, and when the user uses
1448 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1449 create inode could inherit garbage (or old EA information) from a
1450 previously deleted inode.
1452 Fixed a bug in e2fsck so it would notice if a file with an extended
1453 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1456 Added support to filefrag to detect files which are using the new
1457 experimental file extents format, and use the non-ext2 algorithm in
1458 that case. Fixed a bug to avoid reporting a false discontinuity if
1459 there is one or more unallocated blocks at the beginning of a file.
1461 Duplicated a check for noticing whether or not the number of blocks
1462 (given a certain blocksize) is greater than 2**32 when the
1463 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1464 allows mke2fs to automatically use a larger blocksize when creating a
1465 filesystem on a very large device when run on systems that do not
1466 support BLKGETSIZE64.
1468 Fix the I18N build which was broken in e2fsprogs 1.36 because the
1469 build system had been switched to treat the .gmo files as shipped
1470 files (for backwards compatibility with systems that have older GNU
1471 I18N tools installed), but the gen_tarball.in script was still
1472 removing the .gmo files from the official source distribution.
1474 Fixed various Debian packaging issues --- see debian/changelog for
1475 details. (Addresses Debian Bugs ##296769, #299341)
1480 Added new functions to the e2p library which convert between a string
1481 and os_type: e2p_os2string() and e2p_string2os(), and used them to
1482 make the generated binaries more compact.
1484 Fixed a compile-time error on Darwin systems.
1486 Cleaned up the lib/ext2fs Makefile slightly.
1489 E2fsprogs 1.36 (February 4, 2005)
1490 =================================
1492 All of the patches that were applied to Fedore Core 3's
1493 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1494 lot of bug fixes first. Users of Fedora Core 3 are strongly
1495 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1497 Add support for filesystem with the online resizing via resize inode
1498 feature. Fixed numerous bugs from the Fedora patches. The Fedora
1499 patches also didn't bother to do any consistency checking on the
1500 resize inode, or add any tests to the regression test suite. The "-R
1501 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1502 being listed in mke2fs's usage message. All of these shortcomings
1503 have been corrected.
1505 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1506 program. In order to do this, the user must run the commands:
1508 debugfs -w /dev/hdXXX -R "features ^resize_inode"
1509 e2fsck -f /dev/hdXXX
1511 Optionally, the ext2prepare command can be used to re-enable online
1512 resizing after the filesystem has been fixed.
1514 The fsck program will now accept an optional filedescriptor argument
1515 to the -C option. (The Fedora version of this patch would sometimes
1516 cause fsck to ignore a parameter on fsck's command line in some rare
1519 Make sure e2fsprogs doesn't write garbage into the reserved portion of
1522 Make sure resize2fs releases the blocks belonging to the old inode
1523 table blocks when moving the inode table. (Addresses Debian Bug:
1526 Skip the r_resize_inode test if resize2fs is not compiled (due to
1527 configure --disable-resizer)
1529 E2fsck now checks the summary filesystem accounting information, and
1530 if any of the information is obviously wrong, it will force a full
1531 filesystem check. (Addresses Debian Bug #291571)
1533 Fix e2fsck to not complain when the resize_inode feature is enabled,
1534 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1537 Fix e2fsck to note delete symlinks that contain an extended attribute
1538 after the ext_attr feature flag has been cleared. (Addresses Red Hat
1541 Add new utility program, copy_sparse.c, which is very useful
1542 for dealing with large sparse files (such as e2image files).
1544 Add support for jnl_blocks[] for debugfs's set_super_value.
1546 Fix filefrag so that it works correctly with sparse files.
1548 Filefrag -v will print first and last blocks.
1550 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1553 Add mke2fs support so that it can support filesystems larger than 4TB
1554 automatically, by retrying with a 4k blocksize if the device size is
1555 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1558 Change blkid to test for NTFS first because Windows sometimes doesn't
1559 clear enough of the parition to confuse the probing routines into
1560 thinking the old filesystem type is still valid. (Addresses Debian
1563 Add support for swap partition label and uuid's in the blkid library.
1565 Add support to the blkid library to recognize Oracle ASM volumes.
1567 Make blkid -t display all devices that match the specified criteria,
1568 not just the first one, and work more consistently when the blkid
1569 cache file is not available or set to /dev/null. (Addresses Debian
1570 Bug #290530 and #292425)
1572 Badblocks will now correctly display block numbers greater than
1573 999,999,999 in its progress display.
1575 The tune2fs program will not allow the user from setting a ridiculous
1576 number of reserved blocks which would cause e2fsck to assume the
1577 superblock was corrupt. E2fsck's standards for what is a ridiculous
1578 number of reserved block has also been relaxed to 50% of the blocks in
1581 The blkid library will return vfat in preference to msdos, and ext3 in
1582 preference to ext2 (if the journalling flag is set) so that mount will
1583 do the right thing. (Addresses Debian bug #287455)
1585 Mke2fs will now use the -E option for extended options; the old -R
1586 (raid options) option is still accepted for backwards compatibility.
1587 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1589 Mke2fs will now accept a size in megabytes, gigabytes, and other units
1590 (via "32m" or "4g" on the command line) if the user finds this more
1591 convenient than specifying a block count.
1593 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1594 cache conherency problem.
1596 Debugfs now supports a new command, set_inode_field, which allows a
1597 user to manually set a specific inode field more conveniently, as well
1598 as set entries in the indirect block map.
1600 Debugfs's set_super_value command has been enhanced so that the user
1601 can set most superblock fields, including the date/time fields and
1602 some of the more newsly added superblock fields.
1604 E2fsprogs programs now accept an offset to be passed to the file
1605 specifiers, via the syntax: "/tmp/test.img?offset=1024".
1607 E2fsprogs programs will now accept blocksizes up to 65536; kernel
1608 support on the x86 doesn't exist for now, but it can be useful on
1609 other architectures with page sizes greater than 4k. There are 2.6
1610 kernel patches out there which enable this, but they are of this
1611 writing still experimental.
1613 The e2image command now takes the -s option which will scramble
1614 directory entries for raw image files.
1616 Fix a file descriptor leak in the filefrag program.
1618 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1621 Fix bug in debugfs where kill_file would lead to errors when deleting
1622 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1624 Fix bug in the blkid library when detecting the ocfs1 filesystem
1626 Remove obsolete EVMS 1.x and a.out DLL support.
1628 E2fsck will attempt to recover from a journal containing illegal blocks.
1630 Fixed two potential ordering constraint problems in e2fsck which might
1631 cause the filesystem to be corrupted if e2fsck is interrupted during a
1632 (extremely narrow) race window. Thanks to Junfeng Yang from the
1633 Stanford Metacompilation group for pointing this out.
1635 Fixed bug in e2fsck where it would not accurately detect whether or
1636 not the system is running on adaptor if the ACPI device representing
1637 the AC adapter didn't correspond to the what was used on IBM
1640 Change e2fsck to accept directories greater than 32MB.
1642 Fix e2fsck so that a checkinterval of zero disables a time-based check
1645 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
1646 to the PAGER environment variable. (Addresses Debian Bug #239547)
1648 Tune2fs will not mark rewrite the superblock if the feature bitmasks
1651 The debugfs program will set the filetype information when creating a
1654 Add debugfs -d option to use a separate source of data blocks when
1655 reading from an e2image file.
1657 Add e2image -I option which allows the e2image metadata to be
1658 installed into a filesystem.
1660 Fixed bug in the badblocks program which caused "done" to always
1661 appear in english even when a translation was available. (Addresses
1664 The blkid program has a new option -o which controls the output format
1665 of the blkid program; this is makes blkid more convenient to use in
1668 Fix a minor bug in uuid library, which was not using the full 14 bits
1669 of clock sequence when generating UUID's.
1671 Fix a Y8.8888K problem in the uuid library.
1673 Logsave now creates a new session id for itself to avoid getting
1674 killed by init whan transitioning between init levels.
1676 Change the licensing of the UUID library to be the 3-clause BSD-style
1677 license; this allows Apple to use the uuid library in Darwin.
1679 Add ocfs and ocfs2 probe support into the blkid library.
1681 Fix a memory and file descriptor leak in the blkid library.
1683 The blkid library will revalidate the device if the system time is
1684 earlier than last verification time of the device, since that
1685 indicates that the system time is probably nottrustworthy.
1687 The blkid library will override the default location of the blkid.tab
1688 file by the BLKID_FILE environment variable, if it is available.
1690 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
1692 Add various portability fixes for lame new versions of glibc, Darwin
1693 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
1694 Bugs #239934, #264630, #269044, #255589, #289133)
1696 Add support for Windows 9x/NT under Cygwin.
1698 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
1699 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
1701 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
1703 Update the rpm spec files so that it works better with Fedora core 2
1706 Fixed various Debian packaging issues (see debian/changelog). In
1707 particular, fixed the Debian initrd scripts. (#241183, #248050,
1714 Fixed various gcc -Wall warnings.
1716 The uuid library now has new functions uuid_unparse_upper() and
1717 uuid_unparse_lower() which forces the case of the hex digits to be
1718 upper case, or lower case.
1720 The build process has been speeded up by enhancing the subst program
1721 to update the modtime on the generated files even when the generated
1722 file hasn't changed.
1724 The uuid library now uses C99 stdint.h types instead of custom types.
1726 Updated config.guess and config.sub with newer versions from the FSF.
1728 Removed out of date .cvsignore files from the source distribution.
1730 The ext2fs_unlink() function will return an error if both the name and
1731 inode number are unspecified, to avoid doing something surprising
1732 (such as unconditionally deleting the first directory entry).
1733 Directory entries are now deleted by coalescing them with the previous
1734 directory entry if possible, to avoid directory fragmentation. This
1735 is not an issue with the e2fsprogs suite, but may be a problem for
1736 some of the users of libext2fs, such as e2tools.
1738 Add support for version numbers of the form "1.36-rc1".
1740 Fix build of mke2fs.static.
1742 Add basic ext2fs library support for large (EA in inode) inodes.
1744 The test_io mechanism can now abort after n reads or writes to a
1745 particular block. The block is specified by TEST_IO_BLOCK environment
1746 variable, and the read/write count by the TEST_IO_READ_ABORT and
1747 TEST_IO_WRITE_ABORT environment variables. The block data is now only
1748 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
1750 UUID_DEFINE() in the uuid library now creates a static variable, with
1751 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
1752 be used in header files.
1754 Add support for the install-strip and install-shlibs-strip targets, as
1755 suggested by the GNU coding guielines. "make install" no longer
1756 strips the binaries which are installed.
1758 Remove support for the --enable-old-bitops configure option which was
1759 only for very old sparc systems.
1761 Remove support for --enable-clear-htree; this was only needed during
1762 the early development of the htree patch.
1764 Use Linux-kernel-style makefile output so it is easier to see compiler
1767 Update gettext files to version 0.14.1.
1769 Update to use autoconf 2.5x.
1771 Improved support for compiling e2fsprogs under dietlibc.
1773 Make e2fsprogs portable to Solaris and FreeBSD systems.
1775 Add blkid_verify(), blkid_get_library_version(), and
1776 blkid_parse_version_string() functions to the blkid library.
1778 Add pkg-config files for e2fsprogs's libraries.
1780 Fix "make uninstall" to so that it removes everything that is installed.
1782 Add a configure --enable-maintainer-mode option which enables the
1783 makefile rules to rebuild the configure script from configure.in, and
1784 to reubuild the .gmo files in po directory.
1786 Drop the sparc assembly bitwise operations; it's less efficient
1787 than the GCC 3.4 compile code and triggers compiler warnings on
1788 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
1789 (Addresses Debian Bug #232326)
1792 E2fsprogs 1.35 (February 28, 2004)
1793 ==================================
1795 E2fsck has a new -k option, which in conjunction with the -c options,
1796 preserves the existing badblocks list.
1798 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
1800 E2fsprogs will now deal correctly with symlinks that contain
1801 extended attribute information, which can be created using SE Linux.
1802 (Addresses Debian Bug #232328)
1804 Remove a double longjump into an invalid stack frame bug in e2fsck.
1805 (This was during an abort sequence, which normally worked on Linux and
1806 caused a core dump on other operating systems.)
1808 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
1809 (the NLS library will replace "" with the .po header information).
1811 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
1812 dump due to a division by zero error. (Addresses Debian bug #207082)
1814 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
1815 when reconnecting a directory requires creating a lost+found
1816 directory. (Addresses Debian bug #219640).
1818 Fixed a bug where e2fsck would bomb out if a journal needed to be
1819 replayed when using an alternate superblock.
1821 E2fsck will give an extra grace period before actually forcing a check
1822 if the laptop is running on battery. The next time fsck runs while
1823 the system is on the AC mains, or after the grace period is exceeded,
1824 the filesystem will be checked. (Addresses Debian bug #205177)
1826 E2fsck will inform the user when there are 5 or fewer mounts before a
1827 filesystem check will be forced. (Addresses Debian bug #157194)
1829 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
1830 We now correctly handle the case where there is an overlap between a
1831 block group descriptor or a superblock and a bad block indirect block.
1832 In the case where the indirect block is corrupted, we now suggest
1835 Fix byte swap bugs in e2fsck that caused the journal backup location
1836 in the superblock and symlinks created by SE Linux to be cleared
1837 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
1839 E2fsck -c now replaces the current list of bad blocks with the ones
1842 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
1843 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
1845 Fix a potential bug in e2fsck which could cause it to core dump when
1846 trying to print the location of the backup superblock.
1848 Protect against a potential core dump in e2fsck when printing a
1849 message about backup superblocks.
1851 Add support for backing up the journal inode location in the
1852 superblock. E2fsck will automatically save the journal information in
1853 the superblock if it is not there already, and will use it if the
1854 journal inode appears to be corrupted. ext2fs_add_journal_inode()
1855 will also save the backup information, so that new filesystems created
1856 by mke2fs and filesystems that have journals added via tune2fs will
1857 also have journal location written to the superblock as well.
1858 Debugfs's logdump command has been enhanced so that it can use the
1859 journal information in the superblock.
1861 E2fsck will now update all superblocks when moving the journal inode.
1863 Shrink the size of the e2fsck executable by moving some initialized
1864 variables to the BSS segment.
1866 E2fsck will avoid printing the ^A and ^B characters which bracket the
1867 progress bar when stdout and stdin are a tty device instead of a pipe
1868 to another program. (Addresses Debian bug #204137)
1870 Debugfs's mkdir command will automatically expand the directory if
1871 necessary. (Addresses Debian Bug: #217892)
1873 Fixed a bug in debugfs so that copying a file from /dev/null uses the
1874 correct mode bits. (Addresses Debian Bug: #217456)
1876 If the environment variables DEBUFS_PAGER and PAGER are not set,
1877 debugfs now searches for the appropriate pager to use, beginning with
1878 /usr/bin/pager, and then falling back to 'more' and 'less'.
1879 (Addresses Debian bug #221977)
1881 Debugfs will now support 2.6 device numbers where the major or minor
1882 number may be larger than 255. (Addresses Sourceforge bug #865289)
1884 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
1886 Chattr now stops processing options when it sees '--'. (Addresses
1889 Fix regression tests so they work correctly when e2fsprogs is compiled
1890 with configure --disable-htree.
1892 Fix bug in uuid library when there is no network card and the library
1893 is generating a time-based uuid. The random MAC address was not
1894 correctly generated to be a multicast address.
1896 Add compile_et extensions from Heimdall that were missed the first time
1899 Fix bug in badblocks when using O_DIRECT; we need to make sure that
1900 we're reading from an offset which is page aligned. For read-only and
1901 read-write tests, we try to recover after an error so that we can
1902 continue reading on page-aligned boundaries. (Addresses Debian Bug
1905 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
1908 Updated and clarified various man pages. (Addresses Debian Bug
1909 #206845, #222606, #214920, #232406)
1911 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
1913 Fixed various Debian packaging issues (see debian/changelog).
1918 Fixed a build problem so that e2fsprogs would compile with the
1919 --enable-profile option to configure selected. (Addresses Sourceforge
1922 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
1923 Bugzilla Bug #112448)
1925 Centralize code which calculates the location of the superblock
1926 and block group descriptors so that it is in a single library routine.
1928 Added two new functions, ext2fs_file_open2() and
1929 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
1931 Fix compile_et to output the correct prototype for
1932 initialize_xxx_err_table_r() in the header file. (Addresses Debian
1935 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
1937 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
1938 present. This is for when we try stuffing an int into void * pointer.
1940 Fix type-punning which can cause gcc 3.x to miscompile code by getting
1941 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
1942 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
1943 **'. The EVMS code uses an ugly union approach since we don't want to
1944 modify the EVMS interfaces.
1946 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
1947 aid build process on systems can use invoke GNU make as "gmake".
1949 Added regression testing for mke2fs.
1951 Fixed gcc -Wall nitpicks.
1953 Fixed various compiler warnings.
1955 Add portability fixes for FreeBSD and for using fsctl under Darwin to
1956 support ext2 ioctl's.
1959 E2fsprogs 1.34 (July 25, 2003)
1960 ===============================
1962 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
1963 a tight loop while waiting for a child fsck to exit in some cases.
1964 This burns CPU times which slows down the low-level filesystem check.
1966 Added code to mke2fs to assure that the default block size for a
1967 filesystem is at least as big as the sector size of the device, if it
1970 Changed mke2fs and resize2fs to round the default size of a filesystem
1971 to be an even multiple of the VM pagesize in order to avoid a Linux
1972 kernel bug introduced when the storage of the buffer cache was moved
1973 into the page cache.
1975 Mke2fs will warn the user when creating a filesystem with journaling
1976 and a blocksize greater than 4096. (Addresses Debian bug #193773)
1978 Fixed a bug in resize2fs which caused it to fail on filesystems with a
1979 non-empty bad block list. Resize2fs now discards any blocks on the
1980 badblock list which are no longer part of the filesystem as the result
1981 of a filesystem shrink. (Note: this means that shrinking and then
1982 enlarging a filesystem is no longer a reversible operation;
1983 information about bad blocks in the part of the filesystem which is to
1984 be chopped off will be lost.)
1986 Changed resize2fs so the user can use prefixes to specify the units of
1987 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
1988 and to make the error and informational messages explicitly display
1989 the blocksize used by the filesystem, in order to avoid confusion.
1990 (Addresses Debian bug: #189814)
1992 Added a new debugfs command, dump_unused, which dumps the contents of
1993 all unused blocks to stdout. (Useful as an emergency try-to-find
1994 deleted data command.)
1996 Added a new debugfs command, imap, which prints the location of a
1997 specified inode in the inode table.
1999 Fixed a bug in the badblocks program which caused it to use one bit of
2000 randomness in its non-destructive read/write test, instead of using a
2001 full 8 bits of randomness.
2003 Added a new option (-t) to badblocks, which allows the user to control
2004 the test pattern(s) used when checking a disk.
2006 The blkid probe function now more correctly detects UDF filesystems.
2008 Fixed a bug in the blkid library which caused it to not update its
2009 cache if a filesystem changes from having a label to not having a
2012 Fixed a bug in the blkid library wihch could avoid an infinite loop
2013 in blkid_find_dev_with_tag() if /proc is not mounted and there the
2014 /etc/blkid.tab file has not yet been created.
2016 Fixed the badblocks program so that the destructive read/write test
2017 honors the -c option, and to use O_DIRECT when possible to avoid
2018 thrashing the system block buffer cache.
2020 Fixed various NLS issues.
2021 - Added Czech and Swedish translations
2022 - Removed testing NYC translation
2023 - Fixed NLS support for message abbrevations in e2fsck
2024 - Remove de-utf.po, since we shouldn't have two versions using different
2026 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
2027 simplify the statistics reporting in e2fsck.
2029 Changed configure.in so that its defaults for *BSD systems no longer
2030 build an fsck wrapper, and not to install in /usr/local by default.
2032 Fixed some minor spelling errors/typo's in e2fsck and the configure
2035 Fixed various Debian packaging issues (see debian/changelog).
2037 Updated and clarified man pages. (Addresses Debian Bug #195616)
2042 Fix gcc -Wall nitpicks.
2044 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
2045 NLS support by default. (Added partial workaround for gettext/Darwin
2046 incompatibility problems.)
2048 Added full MIT KRB5 and Himdall compaibility support to the com_err
2049 library and the compile_et program. (Addresses Debian bug #191900)
2051 Added the blkid_known_fstype() function to the blkid library, which
2052 returns true if it is passed a filesystem type which is recognized by
2053 the blkid probing functions.
2055 Improved the documentation for the blkid library.
2057 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
2058 returns the hardware sector size of a device, if it is available.
2060 Added a dependency in the blkid library's .so file to the uuid
2061 library, since the former uses the latter. (Addresses Debian bug
2064 Added --with-diet-libc and --disable-evms to the configure script.
2066 Fixed a minor memory leak in the badblocks program.
2068 Fixed a portability problem in tune2fs --- not all systems have strptime().
2070 Fixed a portability problem in debugfs with the use of getopt() more
2071 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
2074 Add support Windows support to ext2fs_get_device_size().
2076 Added (normally disabled) debugging code to the Unix I/O manager which
2077 causes it to disable all userspace caching if the NO_IO_CACHE is
2080 Changed the test I/O manager so it can always be linked into e2fsck,
2081 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
2082 configure script. The test I/O manager will only print any debugging
2083 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
2084 variables are set, which specifies which I/O operations are logged and
2085 a block number to watch, respectively. The log messages are sent to
2086 stderr by default, unless a filename is specified via the
2087 TEST_IO_LOGFILE environment variable.
2090 E2fsprogs 1.33 (April 21, 2003)
2091 ===============================
2093 Added a new utility program, logsave, which captures the output of a
2094 command in a log file, even if the containing directory hasn't been
2095 mounted yet (in which case the it saves the output in memory until it
2096 can write out the logfile). This is useful for capturing the
2097 output of fsck during the boot sequence.
2099 Fixed some portability problems that were causing problems under
2100 the Cygwin32 environment.
2102 Mke2fs now interprets a negative number to the -b option as a minimum
2105 Fixed a bug in mke2fs which was incorrectly checking the argument to
2106 the -g option if the default block size was used. (Addresses Debian
2109 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
2110 it can not find filesystem checkers for jfs, reseirfs, and xfs.
2112 E2fsck now updates the global free block and inode counters from the
2113 block group specific counters quietly. This is needed for an
2114 experimental patch which eliminates locking the entire filesystem when
2115 allocating blocks or inodes; if the filesystem is not unmounted
2116 cleanly, the global counts may not be accurate.
2118 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
2119 2.0 is not yet supported; this only pulled in the bug fixes: fixed
2120 possible hangs caused by bugs in calling waitpid, and not setting the
2121 pipe to non-blocking mode; also fixed a file descriptor leak; made
2122 sure all functions call log entry/exit functions.)
2124 Badblocks now flushes its output file as bad blocks are discovered.
2126 The uuid library is now more paranoid about assuming the correctness
2127 of the /dev/random device; it mixes in a stream of bytes from
2128 random/srandom, just in case.
2130 Update Debian files to reflect the fact that I am now the Debian
2131 maintainer of e2fsprogs. Other various Debian-specific packaging
2134 Move the source tarball generation functions from the top-level
2135 makefile to the util/gen-tarball script.
2137 Updated the Turkish .po translation file.
2139 Added Heimdal and MIT krb5 extensions to the com_err library to make
2140 it more compatible with com_err libraries from those distributions.
2142 Changed dumpe2fs to always display the superblock fields relating to
2143 the journalling and/or directory indexing feature even if those
2144 features are not enabled.
2146 Updated and clarify copyright statement vis-a-vis alpha releases of
2149 The ss library will now try to dynamically link to the readline
2150 library and use it if it is present in the system. This means that
2151 the debugfs program now has line editing and history features. The
2152 SS_READLINE_PATH environment variable is used to find a readline or
2153 readline-compatible library.
2155 E2fsck now finds most duplicate filenames (all when rebuilding all
2156 directories via the -D option) and offers to delete or rename
2157 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
2159 Fix bug in e2image. When writing out a raw image file, include data
2160 blocks from symlinks that do not store the symlink within the inode.
2162 Fix bug in resize2fs which incorrectly moved the block and inode
2163 bitmaps for sparse superblock filesystems and incorrectly marked
2164 blocks as in use. (Addresses Debian bug #174766)
2166 Added a new shared library, the blkid library, which efficiently
2167 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
2168 and UUID filesystem specifiers without needing to search all of the
2169 devices in the system. Instead, the device is looked up in a cache
2170 file, and then verified to make sure the blkid cache is correct.
2172 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
2173 the device name, using the blkid library. (Addresses Debian bugs
2176 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
2177 used for spaces in device labels.
2179 Removed 32-bit limitations for debugfs's dump command.
2181 If the user specifies a large number of inodes, Mke2fs will
2182 automatically adjust the number of blocks per group to find a valid
2183 set of filesystem parameters.
2185 Add workaround to detect broken MD devices where when some of the
2186 underlying devices are marked read-only, writes to the MD device are
2187 silently dropped. E2fsck will detect if there is an attempt to run
2188 the journal twice, and abort with an error if this is the case.
2189 (Addresses IBM Bugzilla bug #1226)
2191 E2fsck will print an error if more than one of the -p/-a, -n or -y
2192 options are specified.
2194 E2fsck will fix HTREE corruptions in preen mode, without stopping the
2195 boot process. This is needed because the 2.4 ext2 filesystem
2196 accidentally had the INDEX_FL backwards compatibility code removed.
2198 Mke2fs no longer creates filesystems with the dir_index flag set by
2199 default; the user has to specifically request it.
2201 Update and clarified various man pages. (Addresses Debian bugs
2202 #173612, #175233, #175113, and #170497, #185945, #188318)
2204 Created man page for the mk_cmds program (from the libss library).
2209 Fix various gcc -Wall nits.
2211 Fixed a lot of portability problems that caused e2fsprogs not to build
2212 successfully under Solaris and Apple/Darwin.
2214 Fixed a Makefile dependency to allow building e2fsprogs using parallel
2217 Changes to create a subset distribution which consists only of the
2218 et, ss, uuid, and blkid libraries. The configure script and top-level
2219 makefile were changed to support working with a subset distribution.
2221 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
2222 actually used, and might people who are looking for
2223 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
2225 Updated debian files to fix a number of Lintian warnings.
2227 Updated config.guess and config.sub with newer versions from the FSF.
2229 Removed unnecessary libraries from being linked into the fsck, lsattr,
2230 chattr, and blkid executables.
2232 E2fsprogs 1.32 (Nomvember 9, 2002)
2233 ==================================
2235 Fixed a bug in the Unix I/O routines which caused needless writebacks
2236 of clean blocks from the unix_io cache (they were erroneously marked
2237 as being dirty, so they were getting written back to disk before
2238 getting evicted from the disk cache). This was harmless, but it
2239 significantly slowed down e2fsck.
2241 Made some other minor optimizations to the Unix I/O routines to save a
2242 small amount of CPU time.
2244 Updated internationalization files.
2247 E2fsprogs 1.31 (Nomvember 8, 2002)
2248 ==================================
2250 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
2251 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
2252 handling for child process that die unexpectly. Add a hack to force
2253 mkfs to create filesystems that won't cause problems with hardware
2254 that has 2k or 4k minimum blocksize requirements. Read from child
2255 processes in non-blocking mode, so that the GUI continues to update.
2257 Fix e2fsck so that it returns the appropriate exit code when the root
2258 filesystem has been changed, so that system's rc scripts will be told that
2259 the system needs to be rebooted.
2261 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
2262 was set, some of the descriptor blocks that should have been written
2263 out were getting skipped.
2265 Changed e2fsck to force out changes to the backup copies of the
2266 superblock and block group descriptors when important changes are made
2267 to those data structures.
2269 Fix a bug where e2fsck could erroneously mark a filesystem as being
2270 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
2271 introduced in e2fsprogs 1.28.)
2273 If journal debuging is enabled using --enable-jbd-debug, the debugging
2274 level is now set via the E2FSCK_JBD_DEBUG environment variable.
2276 If byteswapping support is disabled using configure --disable-swapfs,
2277 skip the tests which depend on byte-swapping, so that "make check"
2280 Lshattr will now display the indexed directory flag. Also, some of
2281 the more esoteric compression flags are supressed unless compression
2282 support has been enabled.
2287 E2fsprogs 1.30 (October 31, 2002)
2288 =================================
2290 When resizing a filesystem, and inodes need to moved, resize2fs will
2291 update the inode's ctime field, and the mtime field of the containing
2292 directories, so that incremental backups using dump/restore will work
2295 In order to avoid spurious errors, e2fsck wil check the last
2296 superblock write time to determine whether or not it can safely use
2297 the LOW_DTIME checks to determine if there are inodes on the orphan
2298 inode linked list that had somehow gotten disconnected. (Addresses
2299 Sourceforge bug #620980)
2301 Partition in /proc/partitions that being with the string "lvm" are
2302 considered real partitions even if they do not end with a number.
2304 Fixed a bug in the the uuid generation function, where if /dev/urandom
2305 is not present, but /dev/random is, and there isn't sufficient
2306 entropy, the get_random_byte function could spin a loop forever.
2308 E2fsck, mke2fs, etc. will now reliably notice when image files are
2309 mounted using the loopback interface. (Addresses Sourceforge bug
2312 When flushing buffers (as is done by badblocks, for example) check to
2313 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
2314 FDFLUSH ioctl which causes the MD device driver which causes confusing
2315 syslog messages about obselete ioctl messages. (Addresses Sourceforge
2318 Debugfs's write command now checks to see if the destination filename
2319 exists before creating it. (Addresses Sourceforge bug #478195.)
2321 When installing man pages, search for compressed man pages using all
2322 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
2324 Fixed a bug in fsck where multiple filesystems specified on the
2325 command were not being checked in parallel due to a logic bug
2326 introduced to support the FSCK_MAX_INST environment variable.
2328 We have added a new superblock field, s_mkfs_time, which indicates
2329 when a filesystem was created. It is set via mke2fs, and printed out
2330 by dumpe2fs, but is not actually touched by the kernel.
2332 Dumpe2fs has been made more robust by not aborting if there is an
2333 error reading the block/inode bitmaps; instead it will still print out
2334 the location of the block/inode bitmaps and inode table.
2336 Add support for the an alternative block group descriptor layout which
2337 allows for on-line resizing without needing to prepare the filesystem
2338 in advance. (This is the incomat feature flag meta_bg.)
2340 Add support for storing default mount options in the superblock, so
2341 that the filesystem can be mounted with specific mount options without
2342 needing to specify them on the mount command line or in the /etc/fstab
2345 Add support for a new inode flag, which is to be used for indicating
2346 the top of directory hierarchies for the Orlov block allocator.
2348 Fix e2fsck so that if it creates the lost+found directory, it does so
2349 with the more apporpriate permissions of 0700. Also change
2350 mklost+found so that it also creates the directory 0700.
2352 Fixed format bug in e2fsck if NLS is in use.
2354 Add a German translation for e2fsprogs's NLS support.
2356 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
2357 the beginning of the inode table. This won't matter much, since if
2358 there is a bad block at the beginning of the inode table, the root
2359 directory won't be available. But at least e2fsck won't crash in this
2362 Fixed endian problems in the htree code for e2fsck and debugfs.
2364 When byte-swapping a filesystem on a PPC architecture, byte-swap the
2365 bitmaps since the historical big-endian ext2 variant had byte-swapped
2366 bitmaps, and the ext2fs library assumes this. This fixes the
2367 regression test suite on PPC machines.
2369 Fix e2image so that it handles a bad block in the inode table
2372 E2fsck now uses a more sophisticated algorithm to salvage corrupted
2373 directories that recovers more information in the corrupted directory
2376 E2fsck now performs additional consistency checks on indexed (HTREE)
2379 Fix bug where efsck might get confused about whether a completely
2380 empty directory block is an empty leaf block or an interior htree
2381 node. This could cause e2fsck to get confused into think that a valid
2382 indexed directory was corrupted.
2384 E2fsck no longer creates an empty directory entry at the end of a
2385 directory block when optimizing a directory. This would cause some
2386 earlier versions of the dxdir kernel code to corrupt the directory
2387 when attempting to split a node containing an empty directory entry.
2389 E2fsck could sometimes in rare circumstances leave the indexed flag
2390 set after a small directory was optimized by compressing it instead of
2391 indexing it. (This should never happen in real life, since
2392 directories that small wouldn't have been indexed, but better safe
2395 E2fsck now only updates the master superblock in all cases. This
2396 slightly shortens its run time.
2398 Ext2ed can deal with directory entries of length 0; previously it
2399 would get stuck in an infinite loop.
2401 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
2402 specifiers. (Sourceforge patch #613447)
2404 Badblocks will now work correctly on read-only devices such as
2405 CD-ROM's. (Sourceforge patch #600451)
2407 Updated and clarified man pages. (Addresses Debian bug #167108)
2410 E2fsprogs 1.29 (September 24, 2002)
2411 ===================================
2413 Fixed a bug in e2fsck which could corrupt a directory when optimizing
2414 it (via the -D option) or rebuiliding the hash tree index with a 1 in
2415 512 probability, due to a fence post error.
2417 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
2420 Mke2fs now enables the directory indexing flag by default. (Since
2421 this is a compatible feature flag, it's safe to do so.)
2423 Tune2fs will support setting the directory indexing feature flag. It
2424 will automatically set up the default hash algorithm and hash seed
2425 fields in the superblock.
2427 If the bone-headed user enters the root filesystem twice in
2428 /etc/fstab, the -R option which skips the root filesystem will skip
2429 all of them. (Addresses Debian bug #159423). Note! This is not a
2430 precedent for dealing intelligently with any other kind of doubled
2431 entry in /etc/fstab!
2437 Removed perror declaration in lib/et/internal.h. All modern systems
2438 can be expected to define perror() these days. Besides, the lib/et
2439 code wasn't using perror at all anyway. :-)
2442 E2fsprogs 1.28 (August 31, 2002)
2443 ================================
2445 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2446 for setting the htree flag is not included yet, although it can be
2447 manually turned on via the debugfs program.
2449 Clarified e2fsck error message which is printed when it cannot find
2450 sufficient contiguous block when relcating filesystem metadata.
2452 Added support for building an EVMS plugin module for ext2/3. This
2453 module is substantially the same as the EVMS module shipping with EVMS
2454 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
2455 for use with EVMS 1.0 (which did not include the ext2 plugin module),
2456 if the configure --enable-old-evms flag is given.
2458 Fsck will search through EVMS volumes when trying to resolve
2459 filesystem specifications such as LABEL=xxx or UUID=xxx.
2461 Added a new utility program, /sbin/findfs, which will return
2462 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2465 Update and clarified various man pages. (addresses Debian Bug #145044,
2466 #146437, #131350, #151990, #144621, #141938)
2468 If there are no filesystems specified on fsck's command line, fsck now
2469 treat that as if the -As options were given. Previously it would
2470 simply do nothing. (Addresses Debian Bug #153102)
2472 Mke2fs no longer treats a failure to be able to clear the MD signature
2473 at the end of the filesystem as a fatal error. (Addresses Debian Bug
2476 The e2p library functions (which are used by lsattr and chattr) now
2477 double check to make sure the file is a regular file or directory
2478 before attempting to use the ext2 ioctls. Some device drivers
2479 unfortunately respond to the ext2 ioctl's with unknown behaviour.
2480 (Addresses Debian Bug #152029).
2482 The extended attribute handling has been updated to correspond with
2483 the latest V2 bestbits ACL code.
2485 Fixed bug in e2fsck which caused it to not clear the dtime field when
2486 processing truncated inodes on the orphan list. This could cause data
2487 loss(!) if a filesystem is rebooted before a truncate has been
2490 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2491 algorithms. This makes e2fsck much faster in the case of severely
2492 corrupted filesystems where a large number of blocks are claimed by a
2493 large number of inodes. (Thanks to the 2.5 IDE device driver for
2494 inspiring this work.)
2496 Resize2fs has been significantly sped up when shrinking and expanding
2497 a filesystem by a very small number of blocks (for example, when EVMS
2498 is converting a partition to be an EVMS legacy volume).
2500 Added a new option to e2fsck, -D, which will optimize or compress all
2501 of the directories in the filesystem.
2503 E2fsck now catches SIGINT and SIGTERM to make sure it will can
2504 properly clean up and only exit at safe points. Fsck will pass
2505 SIGINT/SIGTERM to its child processes, and wait until they have all
2506 exited before it exits.
2508 The uuid parsing code in the uuid library now properly complains when
2509 an illegally formated uuid is presented to it. (Addresses Debian bug
2512 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2513 and 2.4.17, since the workaround can cause problems when using a 2.4
2514 kernel with an old version of glibc built with the 2.2 headers.
2516 Fixed a bug in mke2fs where it wasn't properly clearing the initial
2517 superblock used by other filesystems. (Addresses Debian bug #147256.)
2519 Added support for the synchronous directory feature written by Andrew
2522 The debugfs program can delete directories using the rmdir command.
2524 Add support for 8k and 16k filesystems (for systems with page sizes
2525 that are greater or equal to 8k or 16k, respectively). Note that
2526 these filesystems can not be mounted on x86 systems, or other systems
2527 with only 4k page sizes, due to limitations in the current Linux VM
2530 Resize2fs requires that the filesystem state be valid and have no
2531 errors; otherwise, e2fsck -f must be run first. (Previously it simply
2532 required that the last fsck time be greater than the last mount time.)
2534 Configure now defaults the man pages directory to /usr/share/man on
2537 E2fsck now offers to truncate inodes which contain too many blocks (so
2538 that i_blocks would overflow. Also fixed handling of large sparse
2541 E2fsck now more completely checks for symlink validity, including
2542 requiring NULL termination and length checks.
2544 E2fsck will offer to try forcing a disk write to remap a bad block
2545 after finding a read error when reading a filesystem metadata block.
2547 Fixed a bug in debugfs which caused the -b and -s options to crash
2548 debugfs, as well as breaking the testb, setb, and clearb functions.
2550 Added a bmap command to debugfs which calculates the logical to
2551 physical block mapping for a particular inode.
2553 Fixed a bug in code which checked to see if a device was mounted which
2554 sometimes (rarely) failed in the case of a plain file.
2556 Fixed a bug in resize2fs where when it reported an error, it would
2557 print a message erroneously indicating that the filesystem had been
2558 resized before it aborted.
2560 When resizing a plain file which is smaller than the requested size,
2561 resize2fs will attempt to extended the file so that programs like
2562 e2fsck will not complain that the file is too small.
2564 Resize2fs will print the actual new size of the filesystem when it is
2567 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2568 information on big-endian systems.
2574 Fixed collisions with C++ reserved words.
2576 Added portability fixes for building e2fsprogs on the HURD and AIX.
2578 Added the ext2ed program for creation of test cases. (ext2ed has many
2579 limitations and bugs which make it unsuitable for production use.)
2581 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2582 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2583 name_len field is byte swampped on big-endian machines, since in the
2584 V2 structure, name_len is a char field which is doesn't need to be
2585 byte swapped --- except if an old-style kernel had byte-swapped the
2586 name_len field as part of the V1 structure.
2589 E2fsprogs 1.27 (March 8, 2002)
2590 ==============================
2592 The warning messages for mke2fs now go to standard error.
2594 Fixed to make sure "make check" runs all of the test programs with
2595 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2597 The mke2fs program checks the boot sector for the BSD disk label, and
2598 avoids erasing it if it is there.
2600 Fixed a bug in e2fsck which caused it to core dump if the journal
2601 inode was missing when it was supposed to be there.
2603 E2fsck now prints ranges in pass 5 when printing deltas for the block
2606 Debugfs's "ls -l" command now will print out the file type information
2607 in the directory entry.
2609 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2610 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2612 Debugfs can now examine the experimental directory indexing
2615 Fixed bug in debugfs which caused it to core dump if modify_inode is
2616 called without an open filesystem.
2618 The debugfs lsdel command now runs its output through a pager first.
2620 When installing manual pages, remove the compressed manual pages first.
2622 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2624 Fix the 2.4 resource limitation workaround introduced in 1.26 which
2625 actually broke things on mips32, sparc32, and Alpha platforms.
2627 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2628 (which is required by the newer libintl libraries).
2633 Fixed various gcc -Wall complaints.
2635 Fixed a few memory leaks in the e2fsck journaling code, and in the
2636 ismounted code checking for a swap device.
2638 Add new inode I/O abstraction interface which exports an inode as
2641 Exported ext2_file_flush as a public interface.
2643 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
2645 Lots of small random portability fixes to make e2fsprogs build under
2646 AIX --- even without the 5L compatibility toolkit, and even using the
2647 uber-crippled AIX native C compiler.
2650 E2fsprogs 1.26 (February 3, 2002)
2651 =================================
2653 Dumpe2fs will keep going now if the bad block inode can't be read.
2654 (Previously it stopped with a fatal error.)
2656 E2fsck will now give an opportunity to run the journal even if the
2657 recovery flag is not set. This is the default behaviour if e2fsck is
2658 using a backup superblock, since the needs_recovery flag will never be
2659 set in the backup superblock copies.
2661 E2fsck now automatically finds the backup superblock/group descriptors
2662 even when the primary superblock is completely destroyed for 2k and 4k
2663 filesystems. (Previously it just guessed/assumed that we were dealing
2664 with a 1k filesystem in that case, and users had to manually specify
2665 the backup superblock number.)
2667 Fixed a bug in e2fsck where it dereferences a null pointer when there
2668 is a problem opening a filesystem in preen mode.
2670 E2fsck now handles external journals correctly; previously it trashed
2671 the external journal device if the journal needed to be replayed.
2673 Work around ulimit incompatibility problem caused by recent 2.4
2674 kernels; the unix IO module will automatically try to set any resource
2675 limits to be infinite on startup.
2677 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
2678 bitmap if it wasn't present and the blocksize was 2k or 4k.
2679 (Addresses Debian Bug #116975)
2681 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
2682 clearing the new V2 fields if they do not make sense or if the ext3
2683 superblock is version 1 superblock.
2685 E2fsck will automatically relocate the ext3 journal from a visible
2686 file (i.e., /.journal) to an hidden inode if the filesystem has been
2687 opened read/write. This allows the users to add a journal while the
2688 filesystem is mounted, but the next time the system is rebooted, the
2689 journal file will disappear. This avoids problems with backups,
2690 stupid operators with superuser bits, etc.
2692 Fix a bug in fsck where it would not support a filesystem type of
2693 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
2695 Fsck now supports fstab entries of the form "ext3,ext2". It will also
2696 automatically identify reiserfs filesystems.
2698 The number of processes spawned by fsck can now be limited using the
2699 FSCK_MAX_INST environment variable.
2701 Fsck now searchs the LVM proc hierarchy to find logical volumes which
2702 should be searched for UUID and label information.
2704 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
2705 limit if at all possible, when opening a block device. (The filesize
2706 limit shouldn't be applied against writes to a block device.)
2708 In mke2fs and e2fsck, specifying the -c option twice will now do
2709 a read/write test on the disk. Update the man pages to encourage
2710 using the -c option, and to discouraging running badblocks separately,
2711 since users tend to forget to set the blocksize when running
2714 Mke2fs now automatically clears the immutable attribute on a
2715 pre-existing .journal file left over from a previous failed attempt to
2716 add a journal to an alreadyy-mounted filesystem.
2718 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
2721 Mke2fs now creates the lost+found directory with permissions of 0700,
2722 so that files that had previously lived in protected directory are
2723 safe if they get dropped in lost+found and the system administrator
2724 doesn't deal with immediately. (Addresses Debian #bug 118443)
2726 Mke2fs and e2fsck (and all programs that use the
2727 ext2fs_check_if_mounted function) will now properly identify that a
2728 device is mounted, even in cases where devfs has confused things with
2729 multiple devices names with the same identity, or if a dim-witted
2730 system administrator has done something stupid like creating device
2731 file aliases in their home directory. Also now checks for swap devices
2732 by using /proc/swaps. (Addresses Debian bug #106622)
2734 Added a new option (-T) to tune2fs which sets the time a filesystem
2737 Speed up e2image when creating sparse raw image files by optimizing
2738 away excess lseek() system calls.
2740 Fix support of large (> 2GB) files when used as a filesystem in
2741 mke2fs, tune2fs, debugfs, and findsuper.
2743 Debugfs's stat and icheck commands now properly deals with large (>
2746 Debugfs's set_super_value command now prints out the list of valid
2747 superblock fields which can be set using the command.
2749 Debugfs's rm and kill_file command now updates the superblock free block
2750 and inode counts, thus keeping the filesystem consistent.
2752 Debugfs's lsdel command now takes an optional argument which allows
2753 the user to only see the most recently deleted files.
2755 A new command (undel) was added to debugfs which automates
2756 undeleting a deleted inode and linking it back to a directory.
2758 Debugfs's ls command now takes a new option, -d, which lists
2759 deleted directory entries.
2761 Debugfs's testb, freeb, setb, and find_free_block commands now take an
2762 optional count argument.
2764 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
2765 be used to signal that a particular inode should not be eligible for
2766 tail-merging --- this is needed for programs like LILO.
2768 The findsuper (an unreleased, uninstalled utility program) has been
2769 improved to add extra validity checks and to add a progress meter.
2770 (It is still an unsupported program; the officially supported way to
2771 recover from a trashed partition table is to use gpart; findsuper is
2772 for wizards only. :-)
2774 Debugfs was fixed to compile with "configure --disable-swapfs".
2776 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
2778 Added new translation file for Turkish.
2783 Fix general gcc -Wall complaints.
2785 E2fsprogs (mostly) works with the dietlibc.
2787 The programming texinfo file has been expanded to include description
2788 of additional libext2fs functions. (Still not compeltely done, but a
2789 lot of the more important functions have been documented.)
2791 Added a umask structure to struct_ext2_filsys, which currently only
2792 modifies the behaviour of ext2fs_mkdir(), but if we add any file
2793 creation functions to libext2fs, we should also make sure they respect
2796 The build-rpm script was fixed to be a bit more safe.
2798 The tests' Makefile now has a way of automating test case creation
2799 for e2fsck, using "make testnew".
2801 Created a new function, ext2fs_dir_iterate2 which passes more
2802 information to the callback function (identical to the one used by
2803 ext2fs_dblist_dir_iterate). The directory iterator functions take a
2804 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
2805 directory entries. If the directory entry is deleted, the callback
2806 function will be called with the entry paraemter set to
2807 DIRENT_DELETED_FILE.
2809 Added new functions, ext2fs_inode_alloc_stats and
2810 ext2fs_block_alloc_stats, which takes updates block/inode allocation
2811 statistics in the bitmaps, block group descriptors, and superblock
2812 when inodes or blocks are allocated or deallocated.
2815 E2fsprogs 1.25 (September 20, 2001)
2816 ===================================
2818 This is primarily a bug-fix release; no new features were added, but
2819 there are a number of embarassing bug fixes and cleanups applied.
2821 Fix a bug mke2fs which causes stack garbage to be written to disk when
2822 zapping disk sectors. (This bug could cause mke2fs to core dump for
2823 some kernels, I suspect with security enhancement patches.)
2825 Remove unneeded #include of <linux/config.h> which was breaking
2826 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
2828 Updated tune2fs man page to reflect the fact that adding or removing a
2829 journal doesn't require running e2fsck.
2831 Remove use of AC_REQUIRE from autoconf which had been used to prevent
2832 AC_CANONICAL_HOST from being called twice; unfortunately this causes
2833 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
2834 used outside of autoconf macros. Fortunately, it doesn't seem to be
2835 necessary any more, anyway.
2837 E2fsck will now not fall back to an alternate superblock if the user
2838 specifies the superblock location explicitly on the command-line.
2839 This allows easier recovery from a situation where the primary
2840 superblock and block groups are slightly corrupted, but the backup
2841 superblocks are completely broken.
2843 Fix problem which caused compile_et and mk_cmds to blow up if
2844 e2fsprogs was in a directory with a pathname that contained spaces.
2846 We are now more paranoid about checking the entry in /etc/mtab to make
2847 sure the filesystem is really mounted, since some broken distributions
2848 (read: Slackware) don't initialize /etc/mtab before checking non-root
2849 filesystems. (Slackware also doesn't check the root filesystem
2850 separately, and reboot if the root filesystem had changes applied to
2851 it, which is dangerous and broken, but there's nothing I can do about
2854 Make UUID library C++ friendly by adding appropriate extern "C"
2855 declarations and using const in the function declarations.
2857 Fix up the com_err texinfo file so that it can product a valid info
2858 file (previously, it could only be used to generate paper
2859 documentation using texinfo.tex).
2862 E2fsprogs 1.24a (September 2, 2001)
2863 ===================================
2865 Fix brown-paper bug in mke2fs which caused it to segfault when
2866 printing the version string.
2869 E2fsprogs 1.24 (August 30, 2001)
2870 ================================
2872 Revert the BLKGETSIZE64 support, since for some distributions, this
2873 ioctl has been used by an unofficial kernel patch to update the last
2874 sector on the disk, and this was causing disk corruption problems as a
2877 Mke2fs is now more careful about zapping swap space signatures and
2878 other filesystem/raid superblock magic values so that programs like
2879 mount who try to use hueristics to determine the filesystem type of a
2880 partition are less likely to be confused.
2882 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
2883 regular file (since Andreas Dilger's on-line resizing tools will set
2886 Fixed some minor texinfo, man pages nits for spelling errors,
2887 texinfo warnings, etc. (Addresses Debian bug #110621.)
2889 E2fsprogs program no longer print the filesystem version number
2890 (i.e. 0.5b), since it only confuses people and doesn't serve any real
2893 E2fsck will once again compile under libc5, since it will supply its
2894 own version of strnlen if necesssary.
2896 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
2897 when specifying the external journal device. tune2fs will also search
2898 devices looking for the externla journal debice when removing.
2900 E2fsprogs 1.23 (August 15, 2001)
2901 ================================
2903 Add initial support for extended attributes (EA); e2fsck will
2904 correctly handle a filesystem with EA's and check the EA blocks for
2907 E2fsck's symlink sanity checking has been cleaned up. It now checks
2908 the i_size value of fast symlinks, and checks for immutable flags
2909 being set of symlinks, etc.
2911 E2fsck now offers to clear inodes which are special files that have a
2912 non-zero i_blocks or i_size field. (The i_size field check was in the
2913 previous version of the code, but due to a bug it didn't offer to
2914 clear the inode unless i_size and i_size_high were both non-zero.)
2916 E2image can now create "raw" image files, which only contain the
2917 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
2918 debugfs, etc., can be run directly on the raw image file.
2920 Add support for the 64-bit block device patches.
2922 Fixed bugs in creating external journals with a 1k blocksize.
2924 Add initial support for external journals (so long as the external
2925 journal only supports a single filesystem) in e2fsck.
2927 Remove requirement for needing to run fsck on a filesystem after
2928 removing a journal (either internal or external).
2930 The man pages now document how to create and manage external journals.
2932 Speed up the check of an ext3 filesystems by avoiding a needless flush
2933 of all of the superblock and block group descriptors.
2935 Speed up creating an internal journal using tune2fs in the case where
2936 the filesystem has a lot blocks already allocated.
2938 Tune2fs has been fixed to make sure that only error messages go to
2939 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
2941 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
2942 now not set the sparse_super feature. (Addresses Debian bug #108165)
2944 Add support in fsck for the filesystem type "auto".
2946 Fsck -A will not try to interpret device names for filesystems which
2947 have a pass number is 0. (Addresses Debian bug #106696).
2949 Fsck prints a warning message if now valid filesystems are passed to
2950 it. (Addresses Debian Bug #107458.)
2952 E2fsck now gives an explicit warning if there filesystem still has
2953 errors at the end of the run. (Addresses Debian bug #104502)
2955 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
2956 reflects an error. E2fsck will also not run the orphan list if the
2957 filesystem contains errors, since the orphan list might be corrupted.
2959 E2fsck now prints the number of large files when given the -v option.
2961 Fixed minor memory leaks in e2fsck.
2963 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
2966 E2fsprogs 1.22 (June 22, 2001)
2967 ==============================
2969 Fixed a bug in e2fsck's handling of orphan inodes which are special
2970 files (i.e., block/character device files, named FIFO's, etc.).
2972 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
2973 tune2fs to fail at adding a journal to a mounted filesystem.
2975 Fixed a few big-endian bugs in e2fsprogs
2976 * The directory block functions were accidentally reporting
2977 some directories as corrupted when they weren't.
2978 * If e2fsprogs is compiled --disable-swapfs, the C language
2979 equivalents weren't being included for big-endian platforms.
2980 (Fixes Debian bug #101686).
2982 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
2987 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
2988 ioctls, and allow them to be defined for non-i386 platforms.
2990 The uuid.h header file is now protected against multiple inclusions.
2992 E2fsprogs is now being developed using BitKeeper. Changed the test
2993 scripts to deal with BK's stripping CR characgters from text files,
2994 and changed the top-level Makefile.in to avoid including BitKeeper
2995 files when generating the source tarball.
2998 E2fsprogs 1.21 (June 15, 2001)
2999 ==============================
3001 Added new configure flags which allow a subset e2fsprogs to be built;
3002 this is most useful for boot floopies, since the resulting shared
3003 libraries and programs are slimmed down by removing features that
3004 aren't necessary for a boot floppy. The new flags that were added
3005 are: --disable-swapfs, which removes support for byte swapping old
3006 legacy PPC/68k filesystems, --disable-debugfs, which removes support
3007 for debugfs from the libext2fs library, --disable-imager, which
3008 removes support for the e2image program, and --disable-resizer, which
3009 removes support for resize2fs.
3011 E2fsck now prints the number of mounts or days elapsed since the last
3012 check when e2fsck is forced to check an otherwise clean filesystem.
3014 Tune2fs now prints an informative message about how often a filesystem
3015 will be checked when adding a journal to the filesystem, to remind the
3016 user that he/she may want to adjust those parameters using tune2fs
3019 Worked around hurd brain-damage which causes e2fsck to sometimes
3020 believe a filesystem is the root filesystem based on device numbers
3021 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
3024 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
3025 erroneous error with the -F option was specified.
3027 Fixed a ext3 recovery bug in the revoke handling; synchronized with
3030 Fixed two bugs in e2fsck's handling of dup block handling, dealing
3031 with relatively uncommon edge cases: a directory with an indirect
3032 block which is claimed by another file, and when the last inode in the
3033 filesystem has blocks claimed by another file.
3035 E2fsck now checks to see if the i_size field of a fast symlink is too
3036 big, and offers to clear the symlink if so.
3038 E2fsck now checks to see if i_size_high of special files is non-zero,
3039 and offers to clear i_size_high.
3041 Fix e2fsck's handling of incompatible journal flags so that the user
3042 has chance to abort, and then has the option to clear out the journal
3043 entirely. (Addresses Debian bug #98527.)
3045 Fixed a bug in fsck which could cause it to core dump if a mix of
3046 standard and non-standard device names are used in /etc/fstab.
3047 (Debian bug #100559)
3049 Fixed a bug in debugfs which caused read errors when copying a file to
3052 The debugfs set_super_value command can now modify the s_lastcheck field.
3054 Fixed a bug in lsattr and chattr which was accidentally introduced in
3055 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
3056 directories correctly because the change modified the layout of struct
3057 dirent to be incompatible with the libe2p shared library.
3059 Cleaned up the mke2fs manual page and included a discussion about why
3060 it's good to periodically check the filesystem even when journaling is
3066 Fix general gcc -Wall complaints.
3068 The types needed by the ext2 header files are now provided by
3069 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
3071 Integers are now preferred to longs when trying to find a 32-bit type
3072 in ext2_types.h. Also, if linux/types.h has already been defined,
3073 don't try to redefine the types.
3075 Fixed make depend script so that it automatically corrects the
3076 pathname cleanups performed by make -M, so I don't have to fix them up
3079 Fixed the d_loaddump test case to be more robust, and not depend on
3082 Removed debugfs's dependence on pread(), which was accidentally
3083 intrudced in e2fsprogs 1.20
3085 Fixed a performance bug in the libext2fs's icount routine; the size
3086 estimate of the icount array was incorrectly being calculated.
3088 Removed use of the badblocks compatibility functions in the e2fsprogs
3091 Added paranoia code which protects against strange cases where /etc
3092 isn't on the root filesystem, or if /etc/mtab doesn't exist.
3094 The header file ext2_types.h is now installed.
3096 Autoconf is used to determine when we are on big-endian machines,
3097 instead of doing run-time tests, to save a few bytes of code.
3099 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
3100 functions are no longer inline functions, which saves space and
3101 doesn't really cost any real performance.
3103 The ext2fs library no longer depends on the e2p library. (What need
3104 there was of it --- namely, fsetflags, was coded in-line).
3106 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
3107 when the user is stupid and tries compiling the package using "make
3110 Miscellaneous code cleanups:
3111 * Added missing files from Makefile.in's SRCS file, so that
3112 their dependencies would be properly calculated.
3113 * Removed redundant code
3114 * Fixed comments in code
3115 * Removed no-longer unneeded argsused #pragma.
3118 E2fsprogs 1.20 (May 20, 2001)
3119 =============================
3121 Add support for replaying the ext3 journal purely in user mode,
3122 including handling the orphaned inode list. Used code contributed by
3123 Andreas Dilger, with bug fixes and the orphaned inode handling done
3126 The mke2fs and tune2fs programs can create or modify a filesystem to
3127 include an ext3 journal. Tune2fs also can be used to remove an ext3
3128 journal from a filesystem.
3130 E2fsck will now check for the existence of a linked list of orphan
3131 inodes in the superblock, and clear those inodes before starting the
3132 rest of the filesystem check (but after the journal playback).
3134 E2fsck now validates the file descriptor passed to the -C option,
3135 which saves against the completion bar getting written to an
3136 unexpected location, such as the disk being checked. (Debian
3137 bug/wishlist #55220)
3139 E2fsck will now bump the filesystem revision number from zero to one
3140 if any of the compatibility bits are set.
3142 Fixed a bug where a badly corrupted directory on a big endian system
3143 could cause e2fsck to die with a bus error. The
3144 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
3145 the ext2 library now does alignment sanity checks on the rec_len field
3146 of the directory entry before using it.
3148 The ext2 library has been enhanced to make tune2fs safe to run on
3149 mounted filesystems. (Users could usually get away with using tune2fs
3150 on mounted filesystems before, but with the advent of ext3 and
3151 journaling, it became important to make tune2fs was *really* safe for
3152 use even when the filesystem being modified is mounted.) E2label is
3153 now implemented by tune2fs using an argv[0] dispatch, so that e2label
3154 is also now safe for use on mounted filesystems.
3156 Added a new program, e2image, which creates a backup of critical ext2
3157 filesystem data structures. The generated image file can be examined
3158 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
3159 the image file to help recover very badly damaged filesystems.
3161 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
3162 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
3163 large file when deciding whether or not the filesystem has large files.
3165 Fixed lsattr and chattr so that they work correctly on large files.
3166 (Fixes Debian bug #72690.)
3168 Removed limitation in get_device_size() which imposed a one terrabyte
3169 filesystem limitation. (Most 2.2 kernels still have a signed int
3170 problem which cause 1 TB block device limitation. Fortunately, the
3171 kernel patches to fix this are much easier than fixing the 2TB
3172 limitation in the kernel. :-)
3174 A max_mount_count of zero is now treated as if no mount count were
3175 set. (Previously, no mount count was indicated by using -1, and a
3176 mount count of zero caused e2fsck to always be run.)
3178 Mke2fs supports two new filesystem types largefile and largefile4.
3180 Mke2fs now adds some randomness in s_max_mount_count so that multiple
3181 filesystems won't be all checked at the same time under normal
3184 Fixed bug in the progress bar printing code which could cause e2fsck
3185 to core dump on an illegal filesystem.
3187 Fixed bug in fsck which could allow more than one instance of e2fsck
3188 to be printing a progress bar. (Debian bug #65267)
3190 Fsck using a UUID or a LABEL specifier will work even if devfs is
3191 compiled into the kernel and not mounted. If the pathnames in
3192 /proc/partitions are incorrect, fsck will search /dev for the correct
3193 device (using the new ext2fs_find_block_device library function).
3194 Fsck now also checks the RAID devices first so that they are properly
3195 found when they are in use. Support has also been added to support
3196 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
3198 Fixed a bug in fsck which caused it not deal properly with 16
3199 byte long filesystem labels.
3201 Fsck's -t option has been made a lot more flexible. The semantics for
3202 what happens if a comma-separated list to fsck has been regularized,
3203 and it is now possible to filter what filesystems will get checked
3204 based what is in the filesystem's fstab entry's option field. (Debian
3207 The dumpe2fs program can now print out the group description
3208 information in hex, and also prints the location of the superblock and
3209 block group descriptor for those block groups that have them.
3211 Mke2fs now clears the ext2 superblock before it starts creating a
3212 filesystem, so that the superblock magic number is only written if the
3213 filesystem creation process successfully completes.
3215 The debugfs program's stat command now pretty-prints the blocks used
3216 by an inode so that it's more compact and informative.
3218 The debugfs stats command now uses the same libe2p code (which is used
3219 by dumpe2fs) to print the superblock header information. This is more
3220 complete, and it avoids a bit of code duplication.
3222 Added a new debugfs command, set_super_value (ssv) which allows the
3223 user to set arbitrary superblock fields.
3225 Debugfs was extended to support inode numbers in hex (by prefixing
3226 them with 0x), and so that modify_inode can set the inode generation
3227 number. Also, there is now a new function command called logdump
3228 which will dump an ext3 journal.
3230 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
3233 Debugfs's dump command now stops immediately upon reporting a disk
3234 read error. (Fixed a bug in ext2fs_file_read library routine which
3235 caused debugfs not to stop.) (Debian bug #79163)
3237 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
3238 checked before /etc/mtab is used, since /proc/mounts is more likely to
3241 Added portability fixes for Solaris and Linux/ia64.
3243 Various manual pages were clarified and cleaned up. (Fixed debian
3244 bugs #63442, #67446, and #87216)
3250 The e2fsck message printer now supports %Iu and %Ig, which will print
3251 out the inode's user and group owners, respectively.
3253 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
3254 that no longer dependent on the system having the correct version of
3255 the kernel header files.
3257 Added a new function to libext2, ext2fs_find_block_device(), which
3258 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
3259 device given its device number.
3261 Added a new function to libext2, ext2fs_sync_device, which centralizes
3262 all of the places which might try to use the BLKFLSBUF or FDFLUSH
3263 ioctls (and usually failing to define them since the system header
3264 files don't usually do this for us, and we're trying to avoid usage of
3265 kernel include files now).
3267 Added new utility programs in tests/progs: random_exercise and
3268 hold_inode. They aren't built by default; they're useful for
3269 exercising ext3 filesystem code.
3271 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
3272 the filesystem close functions to only update the superblock, and to
3273 not touch the block group descriptors. Needed by tune2fs when
3274 modifying a mounted filesystem.
3276 Got rid of struct ext2fs_sb and replaced it with the standard struct
3277 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
3278 source (but not binary) compatibility of some users of the ext2
3279 library. Those applications should just simply do a global search and
3280 replace of struct ext2fs_sb with struct ext2_super_block, and include
3281 the new header file <ext2fs/ext2_fs.h> which defines it.
3283 The ino_t type has been renamed ext2_ino_t to protect applications
3284 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
3285 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
3286 unexpected ABI change.
3288 The Makefiles have been reworked so that "make check" can be run from
3289 the top-level Makefile.
3291 Fix general gcc -Wall complaints and removed dead code.
3293 Remove use of NOARGS, because we assume everyone does ANSI C these
3296 Added build-rpm script from sct.
3298 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
3301 New function ext2fs_flush_icache which must be called if the
3302 application program modifies the inode table blocks without going
3303 through ext2fs_write_inode() interface.
3305 New ext2fs_check_mount_point() function, which will return the mount
3306 point of a device if mounted.
3308 The io_channel abstraction now has an optional interface,
3309 io_channel_write_range, which allows specific byte ranges to be
3312 The unix_io IO channel now supports write-through caching, so that
3313 journal creation is more efficient.
3315 Added x86 assembly language routines to support byte swapping, to
3316 reduce executable size.
3318 Fixed bug in the utility program subst so that it's possible to
3319 replace a substitution variable with a zero-length string.
3321 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
3322 slipped into some of the problem number.
3324 E2fsprogs 1.19 (July 13, 2000)
3325 ==============================
3327 Release the resize2fs program since the timeout before it could
3328 be released under the GPL has finally expired.
3330 Add experimental support needed for the ext2 compression patches.
3331 This requires compiling e2fsprogs with the --enable-compression flag
3332 to the configure script.
3334 Added ext3 journalling support. E2fsck will run the journal (if
3335 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
3336 installed as a symlink to e2fsck. Fsck has been taught about ext3,
3337 and treats it the same as ext2 in terms of the progress bar logic.
3338 Dumpe2fs will display the superblock journaling information if the
3339 filesystem has a journal. The ext2 library will now permit opening an
3340 ext3 filesystem with the recovery flag set. This is necessary for
3341 on-line dump's to work correctly, but there may be issues with this
3342 working well since ext3 is much less agressive about syncing blocks to
3343 the filesystem, since they're safe on the journal.
3345 Tune2fs and e2fsck have been changed to allow the mount_count check to
3346 be disabled by setting max_mount_count to -1. (This was already
3347 supported by the kernel.)
3349 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
3350 are used for ext3 as well.
3352 Added internationalization support for e2fsprogs; must be enabled
3353 by passing --enable-nls to configure.
3355 Always use the provided ext2fs header files to insulate ourselves from
3356 kernel version changes. Which include files are used by e2fsprogs
3357 have also been cleaned up to improve portability.
3359 Limit the number of times that e2fsck updates the progress bar so that
3360 people who are booting using a 9600 baud console don't get swampped by
3363 Improved the loop detection algorithm in e2sck's pass #3 so that it is
3364 much, much faster for large filesystems with a large number of
3367 The memory footprint for e2fsck is now slightly smaller than before.
3369 E2fsck now checks if special devices have a non-zero size, and offers
3370 to clear the size field if it finds such an inode.
3372 E2fsck now checks if special devices have the append-only flag set,
3373 and offers to clear the inode.
3375 E2fsck now properly handles some "should never fail" cases during a
3376 bitmap copy in pass5.
3378 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
3380 E2fsck now calculates the correct location of the backup superblock in
3381 the case of filesystem blocksizes > 1k.
3383 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
3384 which normally didn't cause problems under most filesystem parameters,
3385 but could cause a valid superblock to be rejected in extreme cases.
3386 Other checks for validating superblock values were made more
3389 Added non-destructive write testing to the badblocks program, courtesy
3390 of David Beattie. The badblocks also now has an option to input the
3391 current set of bad blocks, so that known bad blocks are skipped to
3392 speed up the badblocks test. There is also a persistent rescan
3393 feature which causes badblocks to run until it has completed some
3394 number of passes without discovering any new bad blocks.
3396 Badblocks now checks to see if the device is mounted and refuses to do
3397 the tests involving writing to the device if it is mounted. Also,
3398 badblocks now allows the number of blocks to be checked to be
3399 defaulted to the size of the partition.
3401 Fixed a bug in fsck which didn't allow non-root users to be able to
3402 check filesystems if there were any LABEL= or UUID= entries in
3405 The Hurd doesn't support the filetype filesystem feature. The mke2fs
3406 program now makes sure that for the Hurd, the filestype feature is
3407 turned off. E2fsck will check to see if the filetype feature is
3408 turned on for Hurd filesystems, and offer to turn off the feature.
3410 Mke2fs now has a safety check to make sure the number of blocks do not
3411 exceed 32 bits even on a 64 bit platform.
3413 Really fixed a bug in fsck to allow "fsck -As" to run interactive
3414 fsck's. (For those people who like to do interactive fsck's in the
3417 Debugfs has a few new features: the rdump command, which will do a
3418 recursive dump of a directory and all of its contents, and the lcd
3419 command which does a local chdir (much like the ftp command of the
3420 same name). In addition, the debugfs program and the open_filesystem
3421 command now takes three new options: -b and -s, which allows the
3422 blocksize and superblock location to be specified, and the -c option
3423 which is used in catastrophic situations where the block group
3424 descriptors are corrupt. If the -c option is specified, debugfs will
3425 skip trying to read in the block and inode bitmaps.
3427 Debufs's lsdel command was fixed to handle bad blocks in the inode
3430 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
3433 General improvements in error messages
3435 - Mke2fs prints a sane error message if the partition size is zero
3436 (usually because the partition table wasn't reread by the
3437 kernel due to the partition being busy), instead of "invalid
3438 argument passed to ext2 library while initializing superblock".
3440 - Fsck now prints more self-explanatory message if an invalid UUID=
3441 or LABEL= specification is passed to it.
3443 UUID library changed to use the LGPL.
3445 Fixed a bug in the UUID library where very rapid calls to the
3446 time-based UUID generator could cause duplicate UUID's to be returned.
3447 This was not a problem for e2fsprogs, but it could be a problem for
3448 other users of the library.
3450 Make the UUID library more robust in the face of missing or an
3451 improper /dev/urandom or /dev/random files.
3453 Added some random portability fixes for Solaris.
3455 Some minor man page updates.
3457 Fixed a memory leak in the ss library.
3463 We now try to use lseek64 and open64 from the LFS if possible.
3465 The 3rd parameter in e2p's print_flags is now a flags word, instead of
3468 The mark and unmark bitmap functions now return the previous state of
3469 the bit that was being changed, which is useful for some speed
3472 The following functions have been added to enhance the badblocks list
3473 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3474 ext2fs_badblocks_equal.
3476 The ext2 header files now have the latest journalling fields to the
3479 The ext2fs_mkdir function in libext2fs now properly backs out of error
3480 conditions robustly.
3482 Cleaned up makefiles:
3483 - to cleanly compile with the -j flag.
3484 - so distclean removes all generated files.
3485 - so in case of an error while installing header files, the make aborts.
3487 Fix test_script so that it works correctly when compiling in the
3490 The random UUID generation routine has been made slightly better in
3491 the case where /dev/random doesn't exist. (Use of randomly-based UUID
3492 is still not recommended if /dev/random doesn't exist, however; it's
3493 better to use the time/ethernet MAC address UUID in this case.)
3495 Clean up the build process so it's more friendly in case of missing
3498 The ext2fs header file can now be #include'd into C++ programs.
3500 The e2p.h header file is now installed.
3502 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3506 E2fsprogs 1.18 (November 10, 1999)
3507 ==================================
3509 Fix a core dumping bug in e2fsck if an imagic inode is present or
3510 (more rarely) if the filesystem is badly corrupted enough that e2fsck
3511 has to restart pass 1 processing. E2fsck now closes the filesystem
3512 before freeing a large number of its data structures, so in the case
3513 of future memory faults, at least the fixed filesystem will be fully
3516 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3517 imagic inode, it will offer to clear the imagic flag.
3519 E2fsck will now offer to clear the immutable flag on special files
3520 (device/socket/fifos) when running it in non-preen mode.
3522 E2fsck will now set the filetype when creating /lost+found, and when
3523 connected orphaned inodes to /lost+found.
3525 Debugfs's ncheck and icheck commands now handles the case where there
3526 are bad blocks in the inode table without bombing out.
3528 The badblocks list processing code has been made more efficiently for
3529 appending a large number of (ordered) badblocks to the badblocks list.
3531 Some minor man page updates.
3533 Fsck now allows interactive e2fsck's when using fsck -As (not a common
3534 mode, but some people like to do this in boot scripts for silly reasons).
3539 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3540 with the problem code convention.
3542 The badblocks list regression test program has been updated to work
3543 with previously made API name changes.
3545 The ext2fs_free() command now uses the new badblocks API to avoid
3546 using the compatibility layer.
3548 Added new regression test cases; the run_e2fsck test script now
3549 supports the ability for a test case to run a prepratory command
3550 before running e2fsck.
3552 E2fsprogs 1.17 (October 26, 1999)
3553 =================================
3555 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3558 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3559 thus potentially causing problems if a binary UUID contained a NULL
3562 E2fsck now uses stricter checks for directory entries in pass 2:
3563 zero-length filenames are not allowed; neither are 8 byte long
3566 The debugfs "dirty" command now clears the filesystem valid bit.
3567 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
3568 bit in the in-core superblock image. The new functionality is more
3569 what the user expects, and is more useful.)
3571 Added a debugging hook to test parallel fsck; if the environment
3572 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3573 will be checked in parallel when they normally would not be.
3578 Fixed some #ifdef's for compilation under the Hurd OS.
3580 Fixed minor W2K compatibility problems.
3582 Fixed some miscellaneous GCC warnings.
3585 E2fsprogs 1.16 (October 22, 1999)
3586 =================================
3588 Fixed a race condition bug in fsck; when printing a progress bar, if
3589 checking multiple filesystems in parallel, it was possible for fsck to
3590 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3591 handler, which would cause it to terminate with a signal 10.
3593 E2fsck now properly handles filesystems that have the
3594 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3595 filesystem into using or not using FILETYPE feature.
3597 E2fsck now properly handles filesystems that have the IMAGIC feature
3598 turned on (this is used on Linux AFS servers).
3600 The mke2fs program now creates filesystems that have the filetype and
3601 sparse_superblock features enabled by default, unless it is run on a
3602 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3603 so there is now a new flag -O which allows the user to specify with
3604 which features she would like to create the filesystem; "mke2fs -O
3605 none" will create a filesystsem compatible with 2.0 kernels.
3607 The tune2fs program now has a -O option which allows the user to set
3608 and reset "safe" filesystem features. Currently, the only ones which
3609 allows to be modified are the filetype and sparse_superblock features.
3610 Note setting or clearing either feature will require running e2fsck on
3611 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3612 requires that there is enough free space on the filesystem for the
3613 extra superblocks which will be created by e2fsck.)
3615 Debugfs can now set and print filesystem features in the superblock
3616 using the "features" command. Dumpe2fs will print out the complete
3617 set of features when listing the superblock.
3619 Dumpe2fs has new options -f (force) and -h (header-only).
3621 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3622 message to come up. This could happen when decrementing or
3623 incrementing a link count could result in an overflow.
3625 Fixed a bug in e2fsck where the block count on the lost+found
3626 directory would not be properly incremented when the directory was
3627 expanded to the point where an indirect block needed to be allocated.
3629 E2fsck now makes some additional sanity checks on the superblock to
3630 avoid crashing or giving a memory allocation error if some of the
3631 values in the superblock are unresonable (but the superblock otherwise
3634 Fixed a bug in e2fsck where a very badly corrupted filesystem might
3635 require two passes to completely fix the filesystem. This happened if
3636 an inode claimed blocks that was part of the filesystem metadata
3637 (typically, when garbage was written into an inode table or indirect
3638 block, since this kind of filesystem corruption normally doesn't
3641 On the Alpha, glibc declares st_flags although it isn't actually used;
3642 the configure script was improved to detect this case so that
3643 e2fsprogs can avoid using the non-functional stat field.
3645 The manual pages were updated to use a more consistent formatting
3646 style consistent with standard Unix man pages. Mke2fs's man page
3647 added documentation for a few previously undocumented options.
3649 Fixed minor display bugs in tune2fs and mke2fs.
3654 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
3656 Added features to parse and print feature strings into the e2p library.
3657 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
3659 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
3660 whose directory entries contain proper filetype information if the
3661 filesystem supports it.
3663 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
3664 the directory entry filetype information. This is used to set the
3665 directory entry filetype information if the filesystem supports it.
3667 Fixed a bug in ext2fs_expand_dir() where the block count in a
3668 directory's inode would not be properly incremented when the directory
3669 was expanded to the point where an indirect block needed to be
3673 E2fsprogs 1.15 (July 18, 1999)
3674 ==============================
3676 Add configuration checks so that e2fsprogs will compile cleanly on
3677 Linux 2.3 kernels that have renamed i_version to i_generation.
3679 E2fsck now prints a progress/completion bar (and not just a simple
3680 spinner) if the -C0 option is requested or if it receives a SIGUSR1
3681 signal. Fsck will automatically manage the (potentially muliple)
3682 e2fsck processes to print completion bars if it is given a -C option,
3683 with the right thing happening if multiple filesystems are being
3684 checked in parallel.
3686 Mke2fs now has better automatic hueristics to determine the filesystem
3687 parameters to be used for a particular filesystem. Added a new option
3688 -T which allows the user to specify how the filesystem is to be used,
3689 which helps mke2fs do a better job selecting the filesystem parameters.
3691 Mke2fs now creates revision 1 filesystems by default, and with the
3692 sparse superblock feature enabled. The sparse superblock feature is
3693 not understood by Linux 2.0 kernels, so they will only allow read-only
3694 mounts of filesystems with this sparse superblocks.
3696 Fix bug where if /dev/null couldn't be opened (should never happen),
3697 e2fsck would hang in a tight loop.
3699 Make e2fsck handle the case where /lost+found isn't a directory.
3701 E2fsck now uses mallinfo if it exists to get accurate statistics about
3704 Fix bug in e2fsck where it wouldn't check to see if a disconnected
3705 inode had any problems before connecting it to /lost+found.
3707 Add check to e2fsck so it makes sure that total number of inodes in
3708 the filesystem is a sane number.
3710 Fix fencepost error when clearing an the end of the block bitmap which
3711 caused the last block in the bitmap not to get cleared.
3713 Cleaned up a number of messages in e2fsck:
3714 * The message "Group's #'s copy of the group descriptor..."
3715 was fixed so that the correct number would be displayed.
3716 * Added missing space in the "disk write-protected" error messsage
3717 * Cleaned up the error message printed when a non-interactive
3718 e2fsck needs to abort a check because the filesystem
3719 appears to be mounted.
3721 Added a new command-line utility, uuidgen, which will create and print
3724 Make debugfs's icheck command more robust by checking to make sure an
3725 inode has valid blocks before interarting over the inode's blocks.
3727 UUID generation now uses a random-based scheme whenever possible to
3728 prevent potential privacy problems.
3730 Man pages for all of the UUID functions in the lirbary were added.
3732 Fixed bug in fsck so it won't coredump if a filesystem not in
3733 /etc/fstab is given to it.
3735 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
3736 that most of the other mount utilities understands.
3738 Mke2fs will make a filesystem even if it appears mounted if the force
3741 Dumpe2fs has new command-line options which allow a filesystem expert
3742 to specify the superblock and blocksize when opening a filesystem.
3743 This is mainly useful when examining the remains of a toasted
3746 The badblocks program has been updated to display correctly on disks
3747 with large block numbers.
3749 The badblocks program no longer gives spurious errors when errors
3750 occur on non-block boundaries, which is common if the blocksize is
3753 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
3754 MKE2FS_SYNC environment variable is set. This is to work around a VM
3755 bug in the 2.0 kernel. I've heard a report that a RAID user was able
3756 to trigger it even using a 2.2 kernel, but hopefully it will not be
3757 needed for most Linux 2.2 users.
3759 Fixed miscellaneous documentation and man pages.
3764 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
3765 in e2fsck's pass1.c really should have been static.
3767 The return value of the uuid_compare() function was changed to make it
3768 match with the convetions used by strcmp, memcmp, and Paul Leach's
3769 UUID sample document.
3771 The "make depend" process has now been made more automated; it now
3772 automatically word-wraps the dependencies, and only replaces source
3773 Makefile.in if there has been a change in the dependencies. Also, a
3774 top-level "make depend" now recurses through all the subdirectories
3777 The Makefile in .../util has been changed so that subst is built using
3778 the native C compiler during a cross-compilation, since the subst
3779 program is only used during the build process. Also add an explicit
3780 rule to build util/subst by cd'ing to the correct directory and
3783 The man directories are defined in terms mandir, so that the configure
3784 script can override the location of the manual pages.
3786 The config files have been updated to recognize new machine types for
3787 both the i386 and alpha families.
3789 Fsck has been modified so that it will accurately create an
3790 fsck_instance even when the noexecute flag is set. This allows for
3791 accurate debugging of the fsck pass structure. Also, when the verbose
3792 flag is given twice, fsck will print debugging information about when
3793 fsck is waiting for jobs to finish.
3796 E2fsprogs 1.14 (January 9, 1999)
3797 ================================
3799 Fix the fstab parsing code so that it can handle blank lines and
3800 comment characters. Also, missing pass numbers need to be treated as
3803 Fixed a bug in e2fsck where under some circumstances (when e2fsck
3804 needs to restart processing after fixing an egregious inconsistency)
3805 it would try to access already freed memory.
3807 E2fsck now prints non-printable characters in directory entries and
3808 pathnames using '^' and 'M-' notation.
3810 Fixed chattr so that it will ignore symbolic links when doing
3811 recursive descent traversals. For both chattr and lsattr, no longer
3812 print the version string unless the -V option is given.
3814 Allow the system administrator to directly specify the number of
3815 inodes desired in the filesystem, for some special cases where this is
3818 Fix portability problems so that e2fsprogs can be compiled under Linux
3819 1.2 systems and Solaris systems.
3821 Update the config.guess file with a more recent version that will
3822 identify newer Linux platforms.
3827 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
3828 an inode number of zero is passed to them.
3830 E2fsprogs 1.13 (December 15, 1998)
3831 ==================================
3833 Fixed a bug in debugfs where an error messages weren't getting printed
3834 when the ext2 library routines to read inodes returned errors in the
3835 stat, cmri and rm commands.
3837 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
3838 provided, it won't create an inode table smaller than the minimum
3839 number of inodes required for a proper ext2 filesystem.
3841 Fsck now parses the /etc/fstab file directly (instead of using
3842 getmntent()), so that it can distinguish between a missing pass number
3843 field and pass number field of zero. This caused problems for
3844 diskless workstations where all of the filesystems in /etc/fstab have
3845 an explicit pass number of zero, and fsck could not distinguish this
3846 from a /etc/fstab file with missing pass numbers.
3848 E2fsck will create a /lost+found directory if there isn't one in the
3849 filesystem, since it's safer to create the lost+found directory before
3852 Fixed e2fsck so that it would detect bogus immutable inodes which
3853 happen to be sockets and FIFO files, and offer to clear them.
3855 If a filesystem has multiple reasons why it needs to be checked, and
3856 one of the reasons is that it is uncleanly mounted, e2fsck will print
3857 that as the reason why the filesystem is being checked.
3859 Cleaned up the output routines of mke2fs so that it doesn't overflow
3860 an 80 column display when formating really big filesystems.
3862 Added a sanity check to e2fsck to make sure that file descriptors 0,
3863 1, 2 are open before opening the hard disk. This avoids a problem
3864 where a broken program might exec e2fsck with those file descriptors
3865 closed, which would cause disastrous results if the kernel returns a
3866 file descriptor for the block device which is also used by FILE *
3869 Fixed up the e2fsck progress reporting functions so that the values
3870 reliably reach 100% at the completion of all of the e2fsck passes.
3872 Fixed minor documentation bugs in man pages and usage messages.
3877 Fixed a number of lint warnings in the ext2fs library and potential
3878 portability problems from other OS's header files that might define
3879 CPP macros for names like "max" and "min".
3881 ext2fs_badblocks_list_add() has been made more efficient when it needs
3882 to grow the bad blocks list.
3884 Fixed a bug in e2fsck which caused it to dereference a freed pointer
3885 just before exiting.
3887 Fixed the substition process for generating the mk_cmds and compile_et
3888 scripts so that they will work outside of the build tree.
3890 Add sanity check to e2fsck so that if an internal routine
3891 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
3892 and causing a core dump. This should never happen, but...
3894 E2fsprogs 1.12 (July 9, 1998)
3895 ==================================
3897 E2fsprogs now works with glibc (at least with the version shipped wtih
3898 RedHat 5.0). The ext2fs_llseek() function should now work even with
3899 i386 ELF shared libraries and if llseek() is not present. We also
3900 explicitly do a configure test to see if (a) llseek is in libc, and
3901 (b) if llseek is declared in the system header files. (See standard
3902 complaints about libc developers don't understand the concept of
3903 compatibility with previous versions of libc.)
3905 The ext2fs library now writes out the block group number in each of
3906 the superblock copies. This makes it easier to automatically
3907 determine the starting block group of the filesystem when the block
3908 group information is trashed.
3910 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
3911 which means that e2fsprogs will ignore the high 8 bits of the
3912 directory entry's name_len field, so that it can be used for other
3915 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
3916 E2fsprogs will now support filesystems with 64-bit sized files.
3918 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
3920 Added new program "e2label", contributed by Andries Brouwer. E2label
3921 provides an easy-to-use interface to modify the filesystem label.
3923 Fixed bug so that lsattr -v works instead of producing a core dump.
3925 Fixed a minor bug in mke2fs so that all groups with bad superblock
3926 backup blocks are printed (not just the first one).
3928 Mke2fs will check the size of the device, and if the user specifies a
3929 filesystem size larger than the apparent size of the device it will
3930 print a warning message and ask if the user wants to proceed.
3932 E2fsck has a new option -C, which sends completion information to the
3933 specified file descriptor. For the most part, this is intended for
3934 programs to use, although -C 0 will print a spinning character to the
3935 stdout device, which may be useful for users who want to see something
3936 happening while e2fsck goes about its business.
3938 Fixed a bug in e2fsck which could cause a core dump when it needs to
3939 expand the /lost+found directory, and sometimes the bitmaps haven't
3940 been merged in. Also fixed a related bug where ext2fs_write_dir_block
3941 was used to write out a non-directory block. (Which would be bad on a
3942 non-Intel platform with byte swapping going on.)
3944 Fixed bug in e2fsck where it would print a "programming error" message
3945 instead of correctly identifying where a bad block was in used when
3946 the bad block was in a non-primary superblock or block group
3947 descriptor. Also fixed a related bug when sparse superblocks are in
3948 use and there is a bad block where a superblock or block group
3949 descriptor would have been in a group that doesn't include a
3952 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
3953 the block group descriptor table is corrupt, it was possible to try to
3954 allocate a huge array, fail, and then abort e2fsck.
3955 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
3956 and subsitutes reasonable values if the descriptors are obviously bogus.
3958 If e2fsck finds a device file which has the immutable flag set and the
3959 i_blocks beyond the normal device number are non-zero, e2fsck will
3960 offer to remove it, since it's probably caused by garbage in the inode
3963 When opening a filesystem, e2fsck specially checks for the EROFS error
3964 code, and prints a specific error message to the user which is more
3967 If the filesystem revision is too high, change the e2fsck to print
3968 that this is either because e2fsck is out of date, or because the
3969 superblock is corrupt.
3971 E2fsck now checks for directories that have duplicate '.' and '..'
3972 entries, and fixes this corruption.
3974 E2fsck no longer forces a sync of the filesystem (with attendant sleep
3975 calls) at all times. The ext2fs_flush() function now performs a sync
3976 only if it needed to write data blocks to disk.
3978 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
3979 certain errors would not be properly reported.
3981 Updated and expanded a few points in the man pages which users
3982 complained wheren't explicit enough.
3984 Added special case byte-swapping code if compiling on the PowerPC, to
3985 accomodate the strange big-endian variant of the ext2 filesystem that
3986 was previously used on the PowerPC port.
3992 Removed C++ keywords from the ext2fs libraries so that it could be
3995 E2fsck's internal organization has now been massively reorganized so
3996 that pass*.c don't have any printf statements. Instead, all problems
3997 are reported through the fix_problem() abstraction interface. E2fsck
3998 has also been revamped so that it can be called as a library from a
4001 Added new fileio primitives in libext2fs for reading and writing
4002 files on an unmounted ext2 filesystem. This interface is now used by
4005 Added a new libext2fs function for mapping logical block numbers of
4006 a file to a physical block number.
4008 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
4009 a block, zeros it, and updates the filesystem accounting records
4012 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
4013 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
4015 The libext2fs functions now use a set of memory allocation wrapper
4016 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
4017 instead of malloc, free, and resize. This makes it easier for us to
4018 be ported to strange environments where malloc, et. al. aren't
4019 necessarily available.
4021 Change the libext2fs fucntion to return ext2-specific error codes
4022 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
4023 and depending on the existence of system error codes (such as EEXIST
4026 Renamed io.h to ext2_io.h to avoid collision with other OS's header
4029 Add protection against ext2_io.h and ext2fs.h being included multiple
4032 The types used for memory lengths, etc. have been made more portable.
4033 In generla, the code has been made 16-bit safe. Added Mark
4034 Habersack's contributed DOS disk i/o routines.
4036 Miscellaneous portability fixes, including not depending on char's
4039 The io_channel structure has a new element, app_data, which is
4040 initialized by the ext2fs routines to contain a copy of the filesystem
4043 ext2fs_check_directory()'s callback function may now return the error
4044 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
4045 really do the checking, despite the presence of the callback function.
4048 E2fsprosg 1.11 (June 17, 1997)
4049 ==============================
4051 Fixed e2fsck to detect (previously ignored) conflicts between the
4052 superblock or block group descriptors and block bitmaps, inode
4053 bitmaps, and inode tables.
4055 Fixed bug in e2fsck so that when the message printed out when a block
4056 or inode bitmap conflicts with other data, it has the correct group
4059 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
4060 to badblocks. This meant that not all of the filesystem was being
4061 tested for bad blocks!
4063 Fixed an array boundary overrun case which cropped up in
4064 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
4067 Adjusted the number of columns printed by mke2fs when displaying the
4068 superblock backups to avoid running over 80 columns when making a
4069 really big filesystem.
4071 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
4072 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
4073 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
4078 Fixed install rule in lib/ss so that ss_err.h is actually getting
4081 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
4082 bassed back to the caller.
4084 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
4085 setting the current inode number (which meant this function wasn't
4088 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
4089 blocks in the bitmap when increasing the size of the bitmap.
4091 Changed the initial number of blocks allocated by ext2fs_init_dblist()
4092 to be more realistic.
4094 Added a new function ext2fs_allocate_group_table, which sets up the
4095 group descriptor information (and allocates inode and block bitmaps,
4096 and inode tables for a particular group). The function was created by
4097 factoring out code form ext2fs_allocate_tables().
4099 Added a new function ext2fs_move_blocks which takes a bitmap of the
4100 blocks to be moved, and moves them to another location on the
4103 Make the unix_io channel's io_channel_flush implementation calls sync()
4104 to to flush the kernel buffers to disk.
4106 Added a new function ext2fs_dblist_count returns the number of
4107 directory blocks in dblist.
4110 E2fsprogs 1.10 (April 24, 1997)
4111 ===============================
4113 Mke2fs once again defaults to creating revision #0 filesystems, since
4114 people were complaining about breaking compatibility with 1.2 kernels.
4115 Warning messages were added to the mke2fs and tune2fs man pages that
4116 the sparse superblock option isn't supported by most kernels yet (1.2
4117 and 2.0 both don't support parse superblocks.)
4119 Added new flag to mke2fs, -R <raid options>, which allows the user to
4120 tell mke2fs about the RAID configuration of the filesystem. Currently
4121 the only supported raid option is "stride" which specifies the width
4124 Fixed bug in e2fsck where pass1b would bomb out if there were any
4125 blocks marked bad in the inode table.
4127 Fixed rare bug in mke2fs where if the user had a very unlucky number
4128 of blocks in a filesystem (probability less than .002) the resulting
4129 filesystem would be corrupt in the last block group.
4131 Fixed bug where if e2fsck tried to allocate a block to fix a
4132 filesystem corruption problem and the filesystem had no free blocks,
4133 ext2fs_new_block() would loop forever.
4135 The configure script now checks explicitly to see if "-static" works,
4136 since that can't be assumed to be true --- RedHat doesn't install
4137 libc-static by default.
4139 Fixed bug in libext2's block iterator functions where under some
4140 cirmcustances, file with holes would cause the bcount parameter to the
4141 callback function to be incorrect. This bug didn't affect any of
4142 e2fsprogs programs, but it was discovered by Paul Mackerras, the
4143 author of the PPC boot loader.
4145 Removed use of static variables to store the inode cache in libext2fs.
4146 This caused problems if more than one filesystem was accessed via
4147 libext2fs (static variables in libraries are generally a bad idea).
4148 Again, this didn't affect e2fsprogs programs, but it was discovered by
4151 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
4152 will compile cleanly with 1.2.13 kernels (even with a.out shared
4158 Added new functions to duplicate an ext2 filesystem handle, and its
4159 associated substructure. New functions: ext2fs_dup_handle(),
4160 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
4161 Other structures, such as the io_channel and the inode_cache, now have
4162 a ref count so that they only get freed when they are no longer used
4163 by any filesystem handle. (These functions were added as part of the
4164 development effort for an ext2 resizer).
4166 E2fsprogs 1.09 (April 14, 1997)
4167 ===============================
4169 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
4170 accidentally introduced in the 1.08 release. The overhead calculation
4171 was accidentally removed, which caused ext2fs_initialize() to not
4172 notice when the filesystem size needed to be adjusted down because
4173 there wasn't enough space in the last block group.
4175 Fixed bug in version parsing library routine; it was always parsing
4176 the library version string, instead of using the passed-in string.
4178 Clarified chattr man page.
4180 E2fsprogs 1.08 (April 10, 1997)
4181 ===============================
4183 E2fsck 1.07 was very slow when checking very large filesystems with a
4184 lot of files that had hard links (i.e., news spools). This was fixed
4185 by seriously revamping the icount abstraction. Added a formal test
4186 suite for the icount abstraction.
4188 Debugfs now has a "-l" option to the "ls" command, which lists the
4189 inode number, permissions, owner, group, size, and name of the files
4192 Fix a bug in e2fsck where when a directory had its blocks moved to
4193 another location during the pass 1b processing, the directory block
4194 list wasn't updated, so pass 2 wouldn't check (and correct) the
4195 correct directory block.
4197 E2fsck will now treat inodes which contain blocks which are claimed by
4198 the filesystem metadata by treating them as multiply claimed blocks.
4199 This way, the data in those blocks can be copied to a new block during
4200 the pass 1b--1d processing.
4202 E2fsck will attempt to determine the correct superblock number and
4203 display it in the diagnostic and warning messages if possible.
4205 Add support for a new (incompatible) feature, "sparse_super". This
4206 feature reduces the number of blocks which contain copies of backup
4207 superblocks and block group descriptors. (It is only an incompatible
4208 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
4209 support a new -s option; e2fsck will recognize filesystems built with
4210 this feature turned on.
4212 E2fsck now checks the library to make sure is the correct version,
4213 using new library functions. (This helps to diagnose incorrectly
4214 installed e2fsprogs distributions.)
4216 Dumpe2fs now prints more information; its now prints the the
4217 filesystem revision number, the filesystem sparse_super feature (if
4218 present), the block ranges for each block group, and the offset from
4219 the beginning of the block group.
4221 Mke2fs now distributes the inode and block bitmap blok so that the
4222 won't be concentrated in one or two disks in RAID/striping setups.
4223 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
4224 choose the largest blocks per group that be chosen. (For 2k blocks,
4225 you can have up to 16384 blocks/group; for 4k blocks, you can have up
4226 to 32768 blocks/group.) Previously mke2fs would not allow
4227 specification of more than 8192 blocks per group, even if you were
4228 using a 2k or 4k block group.
4233 Added a new function ext2fs_create_icount2() which takes a "hint"
4234 argument. This hint argument presets the icount array with the list
4235 of inodes which actually need to be in the icount array. This really
4236 helps to speed up e2fsck.
4238 Added a new function ext2fs_icount_validate() which checks the rep
4239 invariant for the icount structure. This is used mostly for testing.
4241 The error mesasage given when a bad inode number is passed to
4242 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
4243 EXT2FS_UNMARK_ERROR).
4245 Added a new function ext2fs_set_dir_block which sets the block of a
4246 dblist entry, given the directory inode and blockcnt.
4248 Added a new function ext2fs_get_library_version() which returns the
4249 current library version, and ext2fs_parse_version_string() which
4250 returns a version number based on a e2fsprogs version string.
4252 The icount functions will return EINVAL if the passed in inode number
4255 E2fsprogs 1.07 (March 9, 1997)
4256 ==============================
4258 E2fsck is now uses much less memory when checking really large
4259 filesystems (or rather, filesystems with a large number of inodes).
4260 Previously a filesystem with 1 million inodes required 4 megabytes of
4261 memory to store inode count statistics; that storage requirement has
4262 now been reduced to roughly half a megabyte.
4264 E2fsck can now properly deal with bad blocks appearing inside the
4265 inode table. Instead of trying to relocate the inode table (which
4266 often failed because there wasn't enough space), the inodes in the bad
4267 block are marked as in use.
4269 E2fsck will automatically try to use the backup superblocks if the
4270 primary superblocks have a bad magic number or have missing meta-data
4271 blocks (or meta-data blocks which are out of range).
4273 E2fsck's pass 3 has been made more efficient; most noticeable on
4274 filesystems with a very large number of directories.
4276 Completely revamped e2fsck's system of printing problem reports. It
4277 is now table driven, to make them more easily customizeable and
4278 extendable. Error messages which can be printed out during preen mode
4279 are now one line long.
4281 Fixed e2fsck's filesystem swapping code so that it won't try to swap
4282 fast symbolic links or deleted files.
4284 Fixed e2fsck core dumping when fixing a filesystem which has no
4285 directories (not even a root directory).
4287 Added a check to e2fsck to make sure that the length of every
4288 directory entry is a multiple of 4 (since the kernel complains if it
4291 Added a check to e2fsck to make sure that a directory entry isn't a
4292 link to the root directory, since that isn't allowed.
4294 Added a check to e2fsk to now make sure the '.' and '..' directory
4295 entries are null terminated, since the 2.0 kernel requires it.
4297 Added check to write_bitmaps() to make sure the superblock doesn't get
4298 trashed if the inode or block bitmap is marked as being block zero.
4300 Added checking of the new feature set fields in the superblock, to
4301 avoid dealing with new filesystem features that this package wasn't
4304 Fixed a fencepost error in ext2fs_new_block() which would occasionally
4305 try to allocate a block beyond the end of a filesystem.
4307 When the UUID library picks a random IEEE 802 address (because it
4308 can't find one from a network card), it sets the multicast bit, to
4309 avoid conflicting with a legitimate IEEE 802 address.
4311 Mke2fs now sets the root directory's owner to be the real uid of the
4312 user running mke2fs. If the real uid is non-zero, it also sets
4313 the group ownership of the root directory to be the real group-id of
4314 the user running mke2fs.
4316 Mke2fs now has more intelligent error checking when it is given a
4317 non-existent device.
4319 When badblocks is given the -vv option, it now updates the block that
4320 it is currently testing on every block.
4322 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
4323 currently correctly if PATH wasn't already set.
4325 Shared libraries now built with dependencies. This allows the shared
4326 library files to be used with dlopen(); it also makes the transition
4327 to libc 6 easier, since ld.so can tell which libc a particular shared
4328 library expects to use.
4333 Added new abstraction (defined in dblist.c) for maintaining a list of
4334 blocks which belongs to directories. This is used in e2fsck and other
4335 programs which need to iterate over all directories.
4337 Added new functions which test to see if a contiguous range of blocks
4338 (or inodes) are available. (ext2fs_*_bitmap_range).
4340 Added new function (ext2_inode_has_valid_blocks) which returns true if
4341 an inode has valid blocks. (moved from e2fsck code).
4343 Added new function (ext2fs_allocate_tables) which allocates the
4344 meta-data blocks as part of initializing a filesystem. (moved from
4347 Added a new I/O manager for testing purposes. It will either allow a
4348 program to intercept I/O requests, or print debugging messages to
4349 trace the activity of a program using the I/O manager.
4351 The badblocks_list functions now store the bad blocks in a sorted
4352 order, and use a binary search to speed up badblocks_list_test.
4354 The inode scan function ext2fs_get_next_inode() may now return a soft
4355 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
4356 those cases where part of an inode table is missing or there is a bad
4357 block in the inode table.
4359 Added a new function (ext2fs_block_iterate2) which adds new arguments to
4360 the callback function to return a pointer (block and offset) to the
4361 reference of the block.
4363 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
4364 application to jump to a particular block group while doing an inode
4367 The badblocks list functions were renamed from badblocks_* to
4368 ext2fs_badblocks_*. Backwards compatibility functions are available
4369 for now, but programs should be modified to use the new interface.
4371 Some of the library functions were reorganized into separate files to
4372 reduce the size of some programs which statically link against the
4375 Put in some miscellaneous fixes for the Alpha platform.
4378 E2fsprogs 1.06 (October 7, 1996)
4379 ================================
4381 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
4382 smash the backup copies in ext2fs_close(). (The problem was that when
4383 e2fsck -p discovered the problem, while it was closing the filesystem
4384 and exiting, it was also blowing away the backup superblocks on the
4385 disk, which was less than friendly.) We now make it the case that we
4386 only write out the backup superblock and the back block descriptors if
4387 the filesystem is completely free from problems.
4389 Fixed a bug in block_interate in the lib/ext2fs library which caused
4390 e2fsck to fail on GNU Hurd-created filesystems.
4392 Add support for Linux/FT's bootloader, which actually uses
4393 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
4396 Add support for the "A" (no atime update) attribute. (Note: this
4397 attribute is not yet in production kernels.)
4399 The test suite is not automatically run when doing a "make all" from
4400 the top level directory. Users should manually run "make check" if
4401 they wish to run the test suite.
4403 Upon a preenhalt(), make the printed message more explicit that
4404 running e2fsck "MANAULLY" means without the -p or -a options.
4406 In e2fsck, if a disconnected inode is zero-length, offer to clear it
4407 instead of offering to connect it to lost+found.
4409 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
4410 e2fsck to be run over it, change e2fsck to explicitly display this
4413 For dumpe2fs and e2fsck, cause the -V option to print out which
4414 version of the ext2fs library is actually getting used. (This will
4415 help detect mismatches of using a 1.06 utility with a 1.05 library,
4421 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
4422 the naming convention.
4424 In ext2fs_initialize(), make sure the description for the inode bitmap
4425 is correctly initialize.
4427 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4429 E2fsprogs 1.05 (September 7, 1996)
4430 ==================================
4432 Add support for new fields in the ext2 superblock --- volume name,
4433 volume UUID, and last mounted field. Dumpe2fs displays these fields,
4434 tune2fs and mke2fs allows you to set them. E2fsck will automatically
4435 generate a UUID for those volumes that don't have them.
4437 Put in support for e2fsck to recognize HURD specific ext2 features ---
4438 most notably, the translator block. The e2fsprogs tools will now use
4439 the creator_os field in the superblock to correctly handle different
4440 OS-specific variants of the ext2 filesystem.
4442 E2fsck now fixes inodes which have a the deletion time set, but which
4443 have a non-zero i_link_count field by offering to clear the deletion
4444 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4445 ext2 kernel behavior) and offered to unlink the file.
4447 If e2fsck sets the clean bit, but nothing else, set the exit code
4448 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4449 set the filesystem valid bit when it was previously cleared. :-) This
4450 was needed to make the HURD fsck driver happy.
4452 If the user refuses to attach an unattached inode, e2fsck will no
4453 longer set the inode's link count. Otherwise, the inode would end up
4454 getting marked as unused, which might cause loss of data later.
4456 Make the message issued by e2fsck when the superblock is corrupt less
4457 confusing for users. It now mentions that another reason for the
4458 "corrupt superblock" message might be that the partition might not be
4459 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4461 Make the libext2 library more robuest so that e2fsck won't coredump on
4462 an illegal superblock where the blocksize is zero. (f_crashdisk is
4465 By default, create filesystems where the default checkinterval is 6
4466 months (180 days). Linux servers can be robust enough that 20 reboots
4467 can be a long, long time.
4469 Added configure flag --enable-old-bitops, which forces the bitops to
4470 use the old (native) bitmask operations. By default on the sparc
4471 platform, the standard ext2 bit ordering is now used.
4473 Added a new feature to e2fsck to byte-swap filesystems; this can be
4474 used to convert old m68k filesystems to use the standard byte-order
4475 storage for the superblock, inodes, and directory blocks. This
4476 function is invoked by using the '-s' option to e2fsck.
4478 Debugfs's "dump" command has been enhanced so that it writes out the
4479 exact size of the file so that the nulls at the end of the file are
4480 eliminated. The command also accept a new "-p" option which will
4481 attempt preserve to preserve the ownernship, permissions, and
4482 file modification/access times.
4484 Debugfs has two new options, -f and -R. The -R option allows the user
4485 to execute a single debugfs command from the command line. The -f
4486 option allows the user to specify a "command file" containing debugfs
4487 commands which will get executed.
4489 Dumpe2fs now pretty prints the check interval, instead of just
4490 printing the check interval as a number of seconds.
4492 Fix bugs in debugfs: the params command when no filesystem is opened
4493 no longer causes a core dump. It is now possible to unlink a file
4494 when a pathame containing a '/' is specified.
4496 Tune2fs has a new -C option which sets the number of times the
4497 filesystem has been mounted.
4499 Fix the chattr '-v' option so that it actually works. Chattr was
4500 being buggy about the -v option parsing.
4505 The directory lib/uuid contains a set of library routines to generate
4506 DCE compatible UUIDs.
4508 Extended ext2fs_namei() to handle symbolic links. Added new function
4509 ext2fs_nami_follow() which will follow last symbolic link in the case
4510 where the pathname points to a sym link.
4512 The ext2fs_block_iterate function will now return the HURD translator
4513 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4514 iterator to return data blocks only. The ext2fs.h file now defines
4515 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4516 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4517 count field of the iterator callback function.
4519 The test script driver now takes an optional second argument, which is
4520 the test case to be run. This allows you to run a test case without
4521 needing to run the entire test suite.
4523 On Linux ELF systems, install the .so files in the correct places
4524 (/usr/lib). The .so files must be stored in the same directory as the
4527 Fixed miscellaneous HURD compilation issues with header file being
4528 included in the right order.
4530 Fixed debugfs so that it resets optind to zero, not one, since setting
4531 optind to zero is more correct.
4534 E2fsprogs 1.04 (May 16, 1996)
4535 =============================
4537 First "official" (1.03 was a limited release only) to support building
4538 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4541 This package includes a RPM specs file, that it can be built using the
4542 RedHat Package Manager.
4544 E2fsck now prints a hint that if there are lots of incorrectly located
4545 inode bitmaps, block bitmaps, and inode table blocks, the user might
4546 want to try using e2fsck -b 8193 first, to see if that fares any
4549 For ext2 filesystem written with the hurd, debugfs will now print out
4550 the translator field when printing an inode structure.
4552 Lots of miscellaneous linking/installation cleanups:
4554 Libraries are now linked using a relative pathname, instead of
4555 relying on -L working correct. It doesn't, in many cases, including
4556 current versions of GNU ld. This guarantees that the build tree is
4557 linking with the right libraries, instead of the ones installed in
4560 Header files, man pages, and the et/ss shell scripts are now
4561 generated using a custom substitution script, instead of relying on
4562 the configure script. This prevents needless recompilation of
4563 files; in addition, the custom substitution script is much faster.
4565 e2fsck may now be linked dynamically, by using the
4566 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4567 since it increases e2fsck's dependence on other files, but some
4568 people need to save disk space, and other critical programs on their
4569 systems were being linked dynamically anyway.
4571 Programs such as fsck which didn't need to be linked against
4572 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4573 only link against libraries they actually need. Otherwise, those
4574 programs would require the presense of libraries that otherwise
4575 could be removed from a rescuse diskette.
4577 The ss include files are now installed correctly so they can
4578 actually be used by another package.
4580 If the profiling libraries are built, they are now installed on a
4581 "make install-libs".
4584 E2fsprogs 1.03 (March 27, 1996)
4585 ===============================
4587 Change the m68k bit numbering for bitmasks to match the bit numbering
4588 used by all other ext2 implementations. (This change was requested by
4589 the m68k kernel development team.)
4591 Support (in-development) filesystem format revision which supports
4592 (among other things) dynamically sized inodes.
4594 Fixed a bug in the ext2 library so that an intelligent error is
4595 returned if mke2fs is run with a ridiculously small number of blocks
4598 Fixed a bug in the ext2 library which required that the device be
4599 openable in read/write mode in order to determine its size. This
4600 caused e2fsck -n to require read/write access when it was not
4601 previously necessary.
4603 Fixed a bug in e2fsck which casued it to occasionally fail the test
4604 suite depending on which version of the floating point library it was
4607 Fixed a bug in e2fsck so that it now halts with a fatal error when
4608 certain superblock consistency checks fail. Previously it continued
4609 running e2fsck, with some potential confusing/damaging consequences.
4611 Added new flag to fsck which allows the root to be checked in parallel
4612 with other filesytems. This is not the safest thing in the world to
4613 do, but some system administrators really wanted it.
4615 Fixed -Wall flames in lib/ss.
4618 E2fsprogs 1.02 (January 16, 1996)
4619 =================================
4621 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4623 Change e2fsck to print statistics of how many non-contiguous files are
4624 on the system. Note that a file which is larger than 8k blocks, it is
4625 guaranteed to be non-contiguous.
4627 In mke2fs, print a warning message if a user tries to format a whole
4628 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
4629 whole disk, the -F (force) option forces mke2fs to format a whole disk
4632 Fix a bug in fsck where in some cases it might start checking
4633 partitions in the next pass before it finishes checking partitions in
4634 the current pass. This still won't cause two partitions on the same
4635 disk will be checked, so it's rarely a problem in real life.
4637 Patch lsattr so that it won't hang when checking a named pipe.
4639 Minor compilation fixes:
4640 * Fix the order of libraries that were linked in debugfs.
4641 * Allow the sources to be compiled with -ansi turned on.
