1 E2fsprogs 1.40.8 (March 13, 2008)
2 =================================
4 Fixed e2image -I so it works on image files which are larger than 2GB.
6 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
7 the size is larger than the number of blocks found in the inode, don't
8 try to allocate extra empty blocks at the end of the directory to make
9 up the difference; there's no point to doing that. In addition, if
10 the size is not a multiple of a blocksize, always fix it.
12 E2fsck handled a pass 2 "should never happen error" by not giving
13 enough information and then core dumping. Unfortunately, it was all
14 too easy to trigger the "should never happen" situation if a
15 directory's inode size was not correct. This has been fixed, but
16 e2fsck has also been taught how to handle this situation more
17 gracefully, by simply removing the inode hash tree information, so
18 that it can be rebuilt again after e2fsck's pass 3. (Addresses
19 Launchpad Bug: #129395)
21 Resize2fs had a bug resizing large inodes with extended attributes
22 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
23 completely on big-endian systems such as PowerPC. The bug should be
24 completely fixed now. Yay for regression test suites. (Addresses Red
25 Hat Bugzilla: #434893)
27 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
28 translations. Many thanks to Philipp Thomas from Novell for stepping
29 up to become the new German translation maintainer! (Addresses Debian
30 Bugs: #302512, #370247, #401092, #412882).
32 When e2fsck is clearing a corrupt inode's HTREE directory information,
33 make it clear that it is just clearing the HTREE information, not the
36 Fixed spelling mistakes, typos, and otherwise clarified man pages.
41 Add new functions, ext2fs_dblist_get_last() and
42 ext2fs_dblist_drop_last(), which allows the caller to examine the last
43 directory block entry added to the list, and to drop if it necessary.
45 Fixed a portability problem in libblkid with DJGPP.
47 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
48 to Philipp Thomas for pointing this out.
50 If the info files are not built, change "make install" so it doesn't
51 fail with an error code.
54 E2fsprogs 1.40.7 (February 28, 2008)
55 ====================================
57 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
58 depreciate the -s option, since it can result in filesystems which
59 e2fsck can't fix easily. There are very good reasons for wanting to
60 disable sparse_super; users who wants to turn off sparse_super can use
61 debugfs. (Addresses Sourceforge Bug: #1840286)
63 Add missing options to mke2fs's usage message. (Addresses Sourceforge
66 Fix bug in resize2fs when large (greater than 128 byte) inodes are
67 moved when a filesystem is shrunk; it was only moving the first 128
68 bytes, so extended attributes were not getting moved. (Addresses Red
69 Hat Bugzilla: #434893)
71 E2fsck now prints an explicit message when the bad block inode is
72 updated, to avoid confusion about why the filesystem was modified.
73 (Addresses Sourceforge Bug: #756460)
75 Allow mke2fs and tune2fs manipulate the large_file feature.
76 Previously we just let the kernel and e2fsck do this automatically,
77 but e2fsck will no longer automatically clear the large_file feature.
78 It still isn't really necessary to worry about this feature flag
79 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
82 Suppress message about an old-style fstab if the fstab file is empty.
83 (Addresses Debian Bug: #468176)
85 Fix (really minor) bug in debugfs's find_free_block so it avoids
86 reporting a free block more than once if there are too few free blocks
87 in the filesystem. (Addresses Sourceforge Bug: #1096315)
89 Change e2fsck to no longer clear the LARGE_FILES feature flag
90 automatically, when there are no more > 2GB files in the filesystem.
91 It's been almost a decade since there have been kernels that don't
92 support this flag, and e2fsck clears it quietly without telling the
93 user why the filesystem has been changed.
95 Fix bug which could cause libblkid to seg fault if a device mapper
96 volume disappears while it is being probed. (Addresses RedHat
99 Inhance e2fsck's reporting of unsupported filesystem feature flags.
100 (Addresses Sourceforge Feature Request: #1175808)
102 Fix option syntax in dumpe2fs for explicit superblock and blocksize
103 parameters. What was currently documented in the man page has been
104 broken for some time, due to getopt() implementation changes. The
105 option sytax has been changed to one which is can be more portable
106 supported and which is consistent with the format for extended options
107 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
109 Add support to tune2fs to clear the resize_inode feature. This
110 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
112 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
115 Add support for setting RAID stride and stripe-width via mke2fs and
116 tune2fs. Teach dumpe2fs to print the RAID parameters.
118 Add support for setting new superblock fields to debugfs's
121 Add support for printing "mostly-printable" extended attributes in
124 Add support for the -M option to fsck, which causes it to ignore
127 Fix uuidd so that it creates the pid file with the correct pid number.
128 (Addresses Sourceforge Bug: #1893244)
130 Fix various gcc -Wall warnings.
132 Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
134 Fixed spelling mistakes, typos, and otherwise clarified man pages.
135 (Addresses Sourceforge Patch: #1399325)
141 Fixed various Debian packaging issues --- see debian/changelog for
142 details. (Addresses Debian Bug: #466929)
144 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
145 partially filled-in filesystem object on an error, so that e2fsck can
146 print more intelligent error messages.
148 Add a new function e2p_edit_feature2() which allows the caller to
149 specify which feature flags are OK to set or clear, and which returns
150 more specific information about feature flags which are not allowed to
153 Set the C locale in the test_script driver since it uses [A-Za-z].
154 (Addresses Sourceforge Bug: #1890526)
156 Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
159 Change configure.in to avoid using the 'dc' command unless it is
160 absolutely needed. (i.e., when using parsing a WIP-style version
161 number) (Addresses Sourceforge Bug: #1893024)
163 Add portability checks to support compilation under DJGPP.
165 Update to the latest samba tdb code before the LGPLv3 change, which
166 fixes a realloc() leak on failure.
168 Fix memory leak in ext2fs_alloc_block().
170 Fix makefile dependency issues for various install targets.
171 (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
173 Improve descriptions for the r_move_itable and r_resize_inode tests.
176 E2fsprogs 1.40.6 (February 9, 2008)
177 ===================================
179 Add support for returning labels for UDF filesystems in the blkid
182 Fix bug in the blkid library where cached filesystems was not being
183 flushed when opening USB devices returned the error ENOMEDIUM.
184 (Addresses Debian Bug: #463787)
186 Added logic to the blkid library to automatically choose whether a
187 filesystem should be mounted as ext4 or ext4dev, as appropriate.
189 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
191 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
192 configured with --enable-jbd-debug.
194 Document the BLKID_FILE environment variable in the libblkid man page
199 Update e2fsprogs translation template and Vietnamese and Czech translations
201 Fixed various Debian packaging issues --- see debian/changelog for
202 details. (Addresses Debian Bugs: #436058)
204 Don't try to create $DESTDIR/etc/init.d as part of make install as we
205 don't install the init.d script (and it's not the recommended way to
206 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
208 Use thread local storage to fix a theoretical race condition if two
209 threads try to format an unknown error code at the same time in the
213 E2fsprogs 1.40.5 (January 27, 2008)
214 ===================================
216 Fix a potential overflow big in e2image if the device name is too
219 Mke2fs will now create new filesystems with 256 byte inodes and the
220 ext_attr feature flag by default. This allows for much better future
221 compatibity with ext4 and speeds up extended attributes even on ext3
224 Teach e2fsck to ignore certain "safe" filesystem features which are
225 set automatically by the kernel. Having the kernel set features
226 automagically behind the user's back is a bad idea, and we should try
227 to break the kernel of this habit, especially for the newer ext4
228 feature flags. But for now, we will try to avoid needless full checks
229 which can annoy users who are doing fresh installs.
231 Add support in tune2fs and mke2fs for making a filesystem as being "ok
232 to be used with test kernel code". This will be needed for using test
233 filesystems with the latest ext4 kernel code.
235 Change e2fsck -fD so that it sorts non-htree directories by inode
236 numbers instead of by name, since that optimizes performances much
237 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
239 If e2image fills the disk, fix it so it exits right away instead of
240 spewing large numbers of error messages.
241 (Addresses-Sourceforge-Feature-Request: #606508)
243 If ftruncate64() is not available for resize2fs, let it use ftrucate()
244 instead, but have it check to see if the size would get truncated, and
245 skip calling ftruncate in that case.
247 Add support for detecting HFS+ filesystems in the blkid library.
249 Add supprt in the blkid library for ext4/ext4dev filesystems.
251 Fix a bug in blkid where it could die on a floating point exception
252 when presented with a corrupt reiserfs image.
254 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
255 such that UUID string is a fixed length.
257 Add sample python bindings for the uuid library to the contrib
258 directory. (Addresses-Sourceforge-Patches: #778817)
260 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
261 will work with large files. (Addresses Sourceforge Feature Request:
262 #1257500 and Sourceforge Support Request: #1253511)
264 Allow the debugfs 'undel' command to undelete an inode without linking
265 it to a specific destination directory, since this might require
266 allocating blocks that could overwrite some yet-to-be-recovered
267 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
269 Update Swedish translations from the Translation Project.
274 Fix configure handling of --sbindir (which should rarely be used, but
275 someone did complain, so let's fix it). (Addresses Sourceforge Bug:
278 Updated e2fsprogs.spec file to include a new uuidd package
280 Use pkg-config to determine where to find the devmapper library so we
281 can find out where it is located on different distributions.
283 Fix Makefile race so that "make -j3 distclean" works correctly
285 Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
286 especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
289 Fixed spelling mistakes, typos, and otherwise clarified man pages.
291 Fixed various Debian packaging issues --- see debian/changelog for
292 details. (Addresses Debian Bugs: #459403, #459475, #459614)
294 Remove the --enable-dynamic-static configure option, and build e2fsck
295 dynamically by default. If the user wants e2fsck.static, he/she will
296 need to build it via "make -C e2fsck e2fsck.static"
298 Fix various build warnings due to missing prototypes.
299 (Addresses Sourceforge Patch: #1861663, #1861659)
302 E2fsprogs 1.40.4 (December 31, 2007)
303 ====================================
305 Improve time-based UUID generation. A new daemon uuidd, is started
306 automatically by libuuid if necessary. This daemon is setuid to allow
307 updates to /var/lib/libuuid, so the clock sequence number can be
308 stored and so if the clock is set backwards, it can be detected.
309 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
312 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
313 superblocks. This avoids e2fsck from concluding that a full
314 filesystem check is required before backing up the superblock due to
315 changes in the feature flags. (Addresses Debian Bug: #454926)
317 Fix fsck to only treat the '#' character as a comment at the beginning
318 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
319 will cause fsck to issue an bogus warning message.
320 (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
322 Format control characters and characters with the high eighth bit set
323 when printing the contents of the blkid cache, to prevent filesystems
324 with garbage labels from sending escape sequences to the user's screen
325 that might, for example place it in graphics mode. (Addresses Ubuntu
328 Fix sign-extension problem on 64-bit systems in in the com_err
329 library. (Addresses Sourceforge Bug: #1809658)
331 Avoid division by zero error when probing an invalid FAT filesystem in
332 the blkid library. (Addresses Sourceforge Bug: #1831627)
334 Update Dutch, Polish, and Vietnamese translations from the Translation
335 Project. Remove the Rwandan translation upon advice of the
341 Fix the libss "make check" regression test so that it works if the
342 current directory is not in the user's path or if the libss shared
343 library is not installed. (Addresses Sourceforge Bug: #1848974)
345 Fixed spelling mistakes, typos, and otherwise clarified man pages.
346 (Addresses Debian Bugs: #444883, #441872)
348 Fixed various Debian packaging issues --- see debian/changelog for
349 details. (Addresses Debian Bugs: #437720, #451172, #458017)
351 Fix build failure on non-Linux/non-Hurd/non-Masix systems.
352 (Addresses Sourceforge Bug: #1859778)
354 Fix Hurd portability issues. (Addresses Debian Bug: #437720)
357 E2fsprogs 1.40.3 (December 5, 2007)
358 ===================================
360 Fix a potential security vulnerability where an untrusted filesystem
361 can be corrupted in such a way that a program using libext2fs will
362 allocate a buffer which is far too small. This can lead to either a
363 crash or potentially a heap-based buffer overflow crash. No known
364 exploits exist, but main concern is where an untrusted user who
365 possesses privileged access in a guest Xen environment could corrupt a
366 filesystem which is then accessed by the pygrub program, running as
367 root in the dom0 host environment, thus allowing the untrusted user to
368 gain privileged access in the host OS. Thanks to the McAfee AVERT
369 Research group for reporting this issue. (Addresses CVE-2007-5497.)
371 Fix hueristics in blkid which could cause a disk without partitions to
372 be incorrectly skipped when a loopback device is present. (Addresses
373 Red Hat Bugzilla #400321.)
375 Fix e2image so that in raw mode it does not create an image file which
376 is one byte too large.
378 Change mke2fs's usage message so it recommends the preferred -E option
379 instead of the deprecated -R option.
381 Enhance the blkid library so it will recognize squashfs filesystems.
382 (Addresses Red Hat Bugzilla #305151.)
384 Enhance e2fsck so it will force the backup superblocks to be backed up
385 if the filesystem is consistent and key constants have been changed
386 (i.e., by an on-line resize) or by e2fsck in the course of its
389 Enhance blkid's detection of FAT filesystems; so that USB disks with
390 only a single bootable partition will not get missed.
392 E2fsck will no longer mark a filesystem as invalid if it has time
393 errors (i.e., if superblock mount time or last write time is in the
394 future) and the user refuses to fix the problem.
396 The Ubuntu init scripts don't properly set the system time correctly
397 from hardware clock if the hardware clock is configured to tick local
398 time instead of GMT time. Work around this as best as we can by
399 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
400 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
403 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
404 Hat Bugzilla #151533.)
406 Fix e2fsck so that if the superblock is corrupt, but still looks
407 vaguely like an ext2/3/4 superblock, that it automatically tries to
408 fall back to the backup superblock, instead of failing with a hard
411 Make the e2fsprogs program more robust so that they will not crash
412 when opening a corrupt filesystem where s_inode_size is zero.
414 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
415 arguments are detected as such and the parse error is reported to the
416 user. (Addresses Debian Bug #435381.)
418 Change e2fsck so it will not complain if a file has blocks reallocated
419 up to the next multiple of a system's page size.
421 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
422 about (valid) filesystems where the inode table extends to the last
423 block of the block group. (Addresses Red Hat Bugzilla #214765.)
425 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
426 allocating inode tables for some relatively rare odd disk sizes.
427 (Addresses Red Hat Bugzilla #241767.)
429 Add Catalan translation and update Dutch and Swedish translations
430 from the Translation Project.
432 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
433 still had an issue when trying to figure out whether we need to
434 byte-swap fast symlinks that contained extended attributes.
436 Fixed spelling mistakes, typos, and otherwise clarified man pages.
437 (Addresses SourceForge Bug #1821333.)
443 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
445 Add "make check" to the RPM spec file
447 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
448 works correctly when the prefix is not the root directory.
450 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
451 clena up after themselves by deleting the test.img temporary file
452 after completing the test.
454 Fixed a corner case bug ext2fs_unlink() when trying to delete the
455 first directory entry in a directory block and the last directory
456 entry in the previous directory block is not in use. Fortunately
457 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
458 places where it is extremely unlikely to run into this corner case.
460 Fix missing dependency which would cuase parallel builds to fail.
461 (Addresses Sourceforge Bug #1842331.)
463 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
464 calling open(O_CREATE) with a missing mode parameter.
466 Fix the test_ss.c in lib/ss so it can be used as an example
467 application program for the library as well as a regression test
470 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
471 are properly passed back up through the call stack.
473 E2fsprogs 1.40.2 (July 12, 2007)
474 ================================
476 A recent change to e2fsck_add_dir_info() to use tdb files to check
477 filesystems with a very large number of filesystems had a typo which
478 caused us to resize the wrong data structure. This would cause a
479 array overrun leading to malloc pointer corruptions and segfaults.
480 Since we normally can very accurately predict how big the the dirinfo
481 array needs to be, this bug only got triggered on very badly corrupted
484 Fix a bug in e2fsck which caused it to incorrectly salvange
485 directories when the last entry's rec_len is bogusly too big. This
486 resulted in a nonsense filesystem corruption to be reported, and
487 required a second run of e2fsck to fully fix up the directory.
489 Update tune2fs man page to include more discussion of reserved blocks
490 (Addresses Launchpad bug #47817)
492 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
496 E2fsprogs 1.40.1 (July 7, 2007)
497 ===============================
499 Fix bug which could cause libblkid to loop forever. When revalidating
500 a partition where there is obsolete information in /etc/blkid.tab, we
501 end up freeing a the type tag without clearing dev->bid_type, causing
502 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
504 The Turkish translation has a bug in it where it has the translation
505 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
506 @E, recursively, forever, until the stack fills up and e2fsck core
507 dumps. We fix this by making e2fsck stop @-expansions after a
508 recursive depth of 10, which is far more than we need.
509 (Addresses Sourceforge Bug: #1646081)
511 Compile the default mke2fs.conf into mke2fs program. People are
512 getting surprised by mke2fs creating filesystems with different
513 defaults than earlier versions of mke2fs if mke2fs.conf is not
514 present. So we now create a built in version of mke2fs.conf file
515 which is used by mke2fs if the /etc/mke2fs.conf is not present.
516 (Addresses SourceforgeBug: #1745818)
518 Improve the config/parse_types.sh helper script. Fix a potential
519 security problem if e2fsprogs is built as root (as Gentoo does!). In
520 addition fix the script and how it is called from the configure script
521 so that it does the right thing when cross-compiling. (Fixes Gentoo
524 Update Vietnamese, French, and Dutch PO files from the Translation
525 Project. Also created a new e2fsprogs.pot file for translator.
527 Fix bogus strip permission errors when building under Debian. When
528 building the e2fsprogs dpkg's, the dh_strip command emits a large
529 number of error messages caused by the permissions not being right.
530 So run dh_fixperms before running dh_strip.
535 Add new function: profile_set_default(). This function sets the value
536 of the pseudo file "<default>". If the file "<default>" had
537 previously been passed to profile_init(), then def_string parameter
538 will be parsed and used as the profile information for the "<default>"
541 Fix mk_cmds's error reporting so that it is unambiguous that it is the
542 mk_cmds script which is generating the error. (Obviates Gentoo patch:
543 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
545 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
546 priority" environment variable that overrides all others, where as
547 LANG is the lowest priorty environment variable. If LC_ALL is set, it
548 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
549 the all the rest are set. This will assure that the locale when
550 running the test suites is the "C" locale. (Obviates Gentoo patch:
551 e2fsprogs-1.38-tests-locale.patch)
554 E2fsprogs 1.40 (June 29, 2007)
555 ==============================
557 Fix divide by zero error in blkid's NTFS probing logic.
559 Add new blkid -g option which causes the blkid cache to be garbage
562 Fix a bug in libblkid which could cause the internal field bid_type to
563 become corrupted. Fortunately bid_type isn't used much, and bid_label
564 and bid_uuid is only used by debugging code, so the impact of this bug
567 Mke2fs will now store the RAID stride value when a filesystem is
568 created with a requested RAID stride, and then use it automatically in
571 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
572 isn't too big. In some cases Lustre users have tried specifying an
573 inode size of 4096 bytes, while keeping an inode ratio of one inode
576 Improve sanity check in e2fsck's algorithm for finding a backup
577 superblock, so that it won't accidentally find a superblock that was
578 located in the journal, and then later reject it as being not a valid
581 Fix e2fsck get_size logic so that it will work with the Linux floppy
582 driver. The Linux floppy driver is a bit different from the other
583 block device drivers, in that if the device has been opened with
584 O_EXCL, it disallows another open(), even if the second open() does
585 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
587 Fix error checking of badblock's last-block and start-block arguments.
588 (Addresses Debian Bug: #416477)
590 Fix e2fsck so that it doesn't overwrite the backup superblocks when
591 recovering a journal until the master superblock has been confirmed as
594 Change the blkid library to be much more paranoid about concluding
595 that a partition contains an NTFS filesystem, and fetch the UUID and
596 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
599 Factor out the code which sets the default journal size and move it
602 Enhance e2fsck so it will recreate the ext3 journal if the original
603 journal inode was cleared to due it being corrupt after finishing the
606 Fix e2fsck so that it updates the journal inode if it is corrupted and
607 the backup journal information from the superblock was successfully
608 used to recover the filesystem.
610 Fix e2fsck so that it checks all of the blocks in the journal inode
611 for validity. The original code only checked the direct blocks to
612 make sure the journal inode was sane. Unfortunately, if some or all
613 of the indirect or doubly indirect blocks were corrupted, this would
616 Add support in blkid to detect LUKS encrypted partitions.
618 Add extra sanity checks for extended attributes in the case where the
619 size is zero but the offset is very large.
621 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
622 and ext2fs_get_next_inode_full().
624 Clarify the copyright licenses used by the various libraries in
625 the top-level COPYING file (Red Hat Bugzilla: 166058)
627 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
629 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
631 Remove check in e2fsck which requires EA's in inodes to be sorted;
632 they don't need to be sorted, and e2fsck was previously wrongly
633 clearing unsorted EA's stored in the inode structure.
635 Allow mke2fs or tune2fs to create a substantially larger journal (up
636 to 10,240,000 blocks).
638 Fix MD superblock detection, and make sure the correct UUID is
639 reported from the MD superblock.
641 Fix a signed vs. unsigned bug in debugfs.
643 Enhance debugfs's date parser so that it accepts integer values.
645 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
646 file with multiply claimed blocks is hard linked. or not at all if the
647 root directory contains shared blocks
649 Enhance debugfs so it can modify the block group descriptors using the
650 command set_block_group_descriptor.
652 Improve e2fsck's reporting of I/O errors so it's clearer what it was
653 trying to do when an error happens
655 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
656 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:

673 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
674 field on the first pass.
676 Fix e2fsck to set the file type of the '..' entry when connecting
677 a directory to lost+found. (Addresses Lustre Bug: #11645)
679 Enhance e2fsck to recover directories whose modes field were corrupted
680 to look like special files. This is probably only useful in
681 artificial test cases, but it will be useful if we ever do the "inodes
682 in directory" idea for ext4.
684 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
687 Fix resize2fs parsing of size parameter (in sector units). This was
688 actually a bug in libe2p's parse_num_blocks() function. When handling
689 the 's' suffix, it was ignoring the blocksize information passed in
690 from the caller and always interpreting the number in terms of a 1k
691 blocksize. (Addresses Debian Bug: #408298)
693 There was a floating point precision error which could cause e2fsck to
694 loop forever on really big filesystems with a large inode count.

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

708 (Addresses Debian Bug: #371869)
710 Allow debugfs and dumpe2fs to support fs features under development.
712 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
713 ext2fs_open() , which allows application to open filesystes with features
714 which are currently only partially supported by e2fsprogs.
716 Allow unix_io to support offsets greater than 2G (Addresses
717 SourceForge Bug: #1547922)
719 Fixed overflow and signed/unsigned problems caused by the number of
720 blocks or inodes exceeding 2**31 or being close to 2**32-1.
722 Add support for unsigned directory hash calculations with hints in the
723 superblock to fix cross-architectural portability for htree
724 directories with filenames where the high 8th bit is set. (Addresses
727 Fix resize2fs so that it gives user-intelligible error messages if the
728 filesystem or the kernel does not support on-line resizing.

731 Require mke2fs -F -F for really dangerous operations, since -F is
732 needed for less dangerous operations such as creating filesystems
733 images in regular files, or creating filesystems on whole block
734 devices. These relatively innocuous usages should NOT be confused
735 with running mke2fs on an apparently-mounted or in-use filesystem.
737 Allow the default inode size to be specified into the mke2fs.conf
740 Make the smallest default journal size is big enough so that on-line
741 resizing should always work.
743 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
746 Fix debugfs coredump when lsdel is run without an open filesystem
747 (Addresses Debian Bug: #378335)
749 Fix debugfs display bug us that bytes that have the high bit set are
750 displayed as "ec" instead of "ffffffec".
752 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
754 Device mapper scanning wasn't working in the blkid library because the
755 pathnames had an extra "/dev" when they were being probed.
757 Add GFS/GFS2 support to the blkid library.
759 Fix blkid support of empty FAT filesystem labels.
761 Avoid recursing forever (or for a long time) when the blkid library
762 searches for a device and there are symlinks to directories in /dev.
764 Avoid unaligned halfword access in blkid when accessing FAT
765 superblocks, as this will cause Sparc/Solaris systems to throw a

772 Improve the (non-installed, for experts only) findsuper program by
773 printing the uuid and label from the superblocks, as well as the
774 starting and ending offsets of the filesystem given the information in
775 the superblock. Omit by default printing superblocks that are likely
776 found in located in an ext3 journal unless an explicit -j option is
779 Updated Spanish, French and Dutch translations and added Catalan
780 translation. (Addresses Debian bug: #411562)
782 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
783 determining a partition's size, since binary searching to determine
784 the device doesn't work on FreeBSD.
786 Documentation about UUID's is available in enough places, and it's
787 awkward to deal with debian-legal's insanities. So I'm caving in the
788 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
789 don't have do the dfsg tarball. Also remove the rule that only tried
790 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
791 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
793 Fix the info-dir line so that the menu name does not contain a .info
794 prefix. First of all, it's ugly, secondly, it causes the install-info
795 command to fail to remove the com_err info file from the
796 /usr/share/info/dir file when the comerr-dev package is removed and
797 purged. (Addresses Debian Bug: #401711)

810 E2fsck now supports the %It expansion when printing a problem report.
811 It will print the type of the inode in the problem context.
813 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
814 (Addresses Sourceforge Bug: #1565561)
816 Remove unused variables and other lint/gcc -Wall cleanups
818 Add check to ext2fs_get_device_size() so it will return EFBIG for for
819 filesystems contained in regular files where the filesystem image size
820 is returned by stat64().
822 Set local environment variables to C so mk_cmds and compile_et always
823 work. (Addresses SourceForge Bug: #1532177)
825 Added the 64-bit byte swapping function ext2fs_swab64().
827 Added two new helper functions to prevent 2**31/2**32-1 overflow
828 problems: ext2fs_div_ceil() and e2p_percent().
830 Create new ext2fs library inline functions ext2fs_group_first_block()
831 and ext2fs_group_last_block() in order to calculate the starting and
832 ending blocks in a block group.
834 Create the generated files read-only to remind developers not to edit them.
836 Add support for autoconf 2.60 (with backwards compatibility for older
837 versions of autoconf).
839 Added an "make rpm" target to top-level Makefile
841 Added various FreeBSD portability fixes.
843 Exclude mercurial files from the RPM build tree to speed up copy/build.
845 Use root_sysconfdir to define the locations of mke2fs.conf and
846 e2fsck.conf instead of using a hard-coded /etc pathname.
848 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
850 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
852 If diff -u is supported, use it to report test failures.
854 Updates/improvements to RPM spec file
856 Add on-disk format definitions for the following new features:
857 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
858 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
859 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
861 Add a new make target "checked-failed" in the tests directory which
862 reruns any failed tests
864 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
866 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
867 pointer dereferences, memory leaks, etc. None were security-criticial
870 Fix up usage and decrement error messages in the test_icount program
872 Add debugging code to the com_err library; if the environment variable
873 COMERR_DEBUG is set to 1, print out debugging messages as error tables
874 are added and removed from the com_err library. If the
875 COMERR_DEBUG_FILE environment variable is set (and the process is not
876 setuid) the debugging messages may be redirected to a file.
878 Change all of the e2fsprogs programs to use the newer add_error_table()
879 and remove_error_table() interfaces instead of the much older
880 initialize_*_error_table() function.
882 Add TDB support into the ext2fs library. This allows us to have a
883 guaranteed library we can count on always being present so we can
884 store data in an on-disk database.
886 Add support for using TDB to store the icount data, so we don't run out
887 of memory when checking really large filesystems.
889 Change the regression test suite so that it skips empty test directories.
891 Define the l_i_iversion field in ext2_inode. The l_i_version field is
892 now defined from the old l_i_reserved1 field in the ext2 inode. This
893 field will be used to store high 32 bits of the 64-bit inode version
896 Add Makefile production rule for e2fsprogs.spec in case it gets
899 Add new function profile_get_uint() to allow for a clean way to fetch
900 unsigned integers from the context.
902 Add test to make sure the ext2 superblock structure is 1024 bytes.
904 Fix typo in name of f_dup4 regression test
906 Add new function blkid_gc_cache() which performs a garbage collection
907 pass on the /etc/blkid.tab file.
909 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
910 general, only e2fsck (after the filesystem is clean), tune2fs, and
911 resize2fs should change the backup superblocks by default. Most
912 callers of ext2fs_open() should not be touching any superblock fields
913 which require the backups to be touched.
915 Add new function to libext2fs, ext2fs_default_journal_size(), which
916 returns the default journal size.
919 E2fsprogs 1.39 (May 29, 2006)
920 =============================
922 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
923 between 2**31 and 2**32 blocks.
925 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
926 configure the filesystem features, blocksize, and inode_ratio for
927 different filesystem types.
929 Mke2fs will now create filesystems hash trees and on-line resizing
930 enabled by default, based on the new /etc/mke2fs.conf file.
932 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
933 filesystem device node in exclusive mode to prevent accidents by
934 system administrators. In the case of resize2fs and mke2fs, it will
935 only use exclusive mode if the filesystem is not mounted.
937 Fixed a bug in mke2fs which caused it to to fail when creating the
938 resize inode for large filesystems. (Addresses Debian Bug #346580)
940 When allocating space for the RAID filesystems with the stride
941 parameter, mke2fs will now place each portion of the group's inode
942 table right up after the superblock (if present) in order to minimize
943 fragmentation of the freespace.
945 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
946 efficiently by writing the inode and block bitmaps in one pass, thus
947 reducing the number of disk seeks required.
949 Add support for on-line resizing to resize2fs.
951 Fix blkid library so that logic to determine whether or not a device's
952 cached information in /etc/blkid.tab needs to be verified or not
953 doesn't get confused by a system clock which is insane (for example,
954 if the battery is dead on a Macintosh running PPC Linux. (Addresses
955 Red Hat Bug: #182188)
957 The blkid library will now store the UUID of the external journal used
958 by ext3 filesystems, so that in the future, the userspace mount binary
959 can use this to find the location of the external journal and pass
960 this information to the kernel.
962 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
963 control how various options should be handled. See the e2fsck.conf
964 man page for more details. (Addresses Debian Bug: #150295)
966 E2fsck now prints an explanatory message when delaying a filesystem
967 check when the system is running on battery. (Addresses Debian Bug:
970 E2fsck will detect if the superblock's last mount field or last write
971 field is in the future, and offer to fix if so. (Addresses Debian Bug
972 #327580) These problems will be fixed automatically in preen mode
973 since Debian's boot sequence bogusly doesn't set the time correctly
974 until potentially very late in the bootup process, and this can cause
975 false positives which will cause users' systems to fail to boot.
976 (Addresses Debian Bugs #343662 and #343645)
978 E2fsck now checks to see if the superblock hint for the location of
979 the external journal is incorrect, and if so, offer to update it.
980 (Addresses Debian Bug: #355644)
982 Fix e2fsck from segfaulting on disconnected inodes that contain one or
983 more extended attributes. (Addresses Debian Bug: #316736, #318463)
985 E2fsck will stop and print a warning if the user tries running a
986 read/write badblocks test on a read-only mounted root filesystem.
988 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
989 C. Thompson for pointing these out; they were originally found using
992 When resizing a file containing a filesystem, resize2fs will expand or
993 truncate a file as necessary. (Addresses Debian Bug: #271607)
995 Resize2fs will now automatically determine the RAID stride parameter that
996 had been used to create the filesystem, and use that for newly created
997 block groups. The RAID stride parameter may also be manually specified
998 on the command line using the new -S option to resize2fs.
1000 Fix mke2fs so that it correctly creates external journals on
1001 big-endian machines (such as a S/390).
1003 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
1004 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
1005 Chambraud for pointing this out.)
1007 Dumpe2fs will now print the size of the journal (if present).
1009 Fix debugfs's set_inode_field command so it can properly set the frag,
1010 fsize, uid_high, gid_high, and author fields in the inode instead of
1011 silently failing, and so that setting the i_size actually sets i_size
1014 Add a new debugfs command, set_current_time, which sets fs->now so
1015 that regression test suites can repeatedly modify the filesystem's
1018 Fix a bug in debugfs's icheck which would incorrectly report the owner
1019 of an extended attribute block.
1021 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
1022 print a usage message when an illegal option character is given.
1024 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
1025 so it won't core dump. (Addresses SourceForge bug #1424311)
1027 Fix mklost+found so that it creates a full-sized directory on
1028 filesystems with larger block sizes.
1030 Fix a file descriptor leak in blkid library.
1032 Fix a display bug in "badblocks -sv" so that the done message properly
1033 clears the block number at the end of the test. (Addresses Debian Bug
1036 Allow fractional percentages to the -m option in mke2fs and tune2fs

1039 Use fstat/fstat64 in getsize.c if the the target is a regular file,
1040 instead of attempting to do a binary search. Fix some fd leaks in

1044 that the "best" (i.e., leaf) device is probed by the blkid library.
1046 Fix the blkid library so that it notices when an ext2 filesystem is
1049 Improve the blkid's library VFAT/FAT detection; it now understands
1050 labels stored in the root directory, and is more paranoid about
1051 checking the FAT superblock values.
1053 Fixed a fd leak in the uuid library which was causing problems for the
1054 LVM tools. (Addresses Debian Bug: #345832)
1056 Add support for the reiser4 and software suspend partitions to the
1057 blkid library. Also add support for extract the label from iso9660
1060 Fix a compile_et bug which miscount the number of error messages if
1061 continuations are used in the .et file.
1063 Add extra sanity checks to protect users from unusual cirucmstances
1064 where /etc/mtab may not be sane, by checking to see if the device is
1065 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
1068 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian

1095 GNU make (i.e., 3.81).
1097 Add valgrind support to the regression test suites, and eliminate
1098 false positives from valgrind.
1100 Add a regression test suite for the blkid library.
1102 Fix a fencepost error in resize2fs caught by valgrind.
1104 Fix compiler warnings about missing memcpy prototypes.
1106 We no longer have the sparc assembly code in the header file any more,
1107 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
1108 break compiles on the sparc architectures when using gcc.
1110 In the libext2fs library, add the new field fs->now which if non-zero
1111 is used instead of the system time when setting various filesystem
1112 fields (last modified time, last write time, etc.)
1114 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
1115 ext2fs.h which is needed since the inline functions use memcpy().
1116 (Addresses Sourceforge Bug #1251062)
1118 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
1119 the build system when building files in the util directory which are
1120 needed during the build process. This avoids potential problems when
1121 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
1122 are not recognized as valid by the host compiler. (Addresses
1123 Sourceforge Bug #1261547)
1125 Clean up the blkid library by making the superblock and generic i/o
1126 functions to be more generic. Clean up interface to the probe
1127 function, and fix memory leak. Finallly, remove an unneeded reference
1128 to probe.h in the lib/blkid/resolve.c
1130 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
1131 of invalid block #'s.
1133 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
1134 indicate that the the function read/writes the memory location.
1136 Fix various gcc -Wall complaints.
1138 Add a dependency to make sure that the subdirectories are created
1139 before creating all of the object files, in order to address parallel
1140 build problem in the library Makefiles. (Addresses Sourceforge Bug:
1143 Add $(LDFLAGS) to the command line argument when generating an ELF or
1144 Solaris shared library, to allow cross-compile and other builds that
1145 might need to specify -L paths to needed libraries. (Addresses
1146 Sourceforge Bug #1261549)
1148 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
1149 intended for testing purposes. It allows an ext2/ext3 developer to
1150 create very large filesystems using sparse files where most of the
1151 block groups are not initialized and so do not require much disk
1152 space. Eventually it could be used as a way of speeding up mke2fs and
1153 e2fsck for large filesystem, but that would be best done by adding an
1154 RO_COMPAT extension to the filesystem to allow the inode table to be
1155 lazily initialized on a per-block basis, instead of being entirely
1156 initialized or entirely unused on a per-blockgroup basis.
1158 Fix backwards compatibility so e2fsprogs will better compile on Linux
1161 Make test scripts more robust against locale-related environment variables

1183 consistency, and to make life easier for translators. Fixed a few
1184 strings containing English that had not been marked as needing
1185 translations. Removed strings that do not need to be translated, to
1186 make life easier for translators.
1188 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
1189 test to see if a device appears to be in use instead of just relying
1190 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
1192 Fix portability problem in the filefrag program affecting platforms
1193 where the size of an integer is smaller than the size of a long.
1194 (Addresses Debian Bug #309655)
1196 Mke2fs will now use a larger journal by default for filesystems
1197 greater than 4GB. (128 MB instead of 32MB).
1199 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
1200 unless forced. This is to avoid signed vs. unsigned kernel bugs in
1201 block numbers that still need to be fixed.
1203 The blkid program has a new option which will more efficiently search
1204 for device when it is known (or expected) that only one matching
1205 device will be found in the system, such as when doing a lookup by
1208 Debian's e2fsprogs-specific initrd fragment will avoid including
1209 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
1210 and LD_LIBRARY_PATH, and filtering out libraries found in
1211 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
1213 Fixed a potential portability issue in the blkid programs for
1214 architectures where the char type is unsigned. (Addresses Sourceforge
1217 Fix a bug in filefrag so that it doesn't falsely count an extra
1218 discontinuity when the first block found is an indirect block.
1219 (Addresses Debian Bug #307607).
1221 Fix blkid's recognition of cramfs filesystems, and enhance it to be
1222 able to handle cramfs labels.
1224 Fix debugfs's stat command to not core dump when a filesystem is not
1227 Fix e2fsck's handling of error conditions caused by the resize inode
1228 claiming blocks that are also used by other inodes, a filesystem
1229 corruption which was commonly caused by a bug in Fedora Core 3's
1232 Fixed bug in filefrag which caused it to fail on non-ext2/3
1233 filesystems. (Addresses Debian Bug: #303509)
1235 If the superblock last mount time indicates that the system clock may
1236 not be accurate, then e2fsck will omit checking inodes' deletion time
1237 field for indications of a potential corrupted orphaned inode list.
1238 (Previously e2fsck only ommited these LOW_DTIME checks when the
1239 superblock's last write time looked insane.)
1241 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
1242 (Addresses Debian bug #302200)
1244 Make the blkid library more paranoid about being run from setgid
1245 programs, and to use __secure_getenv() from libc if it is available.
1247 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1248 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
1249 and Sourceforge Bug: #1189803)
1251 Updated and fixed translations.
1253 Fixed various Debian packaging issues --- see debian/changelog for
1259 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
1260 changed to take an unsigned int for the bit number. Negative bit
1261 numbers were never allowed (and didn't make any sense), so this should
1262 be a safe change. This is needed to allow safe use of block numbers
1263 greater than or equal to 2**31.
1265 The compile_et program will avoid recreating generated foo_err.c and
1266 foo_err.h files if no changes are necessary. The compile_et program
1267 will also atomically replace these files to avoid a potential parallel
1268 build race problem on SMP systems. (Addresses Sourceforge Bug:
1271 Added a new function to the blkid library, blkid_probe_all_new(),
1272 which only probes newly added disk devices, and change
1273 blkid_find_dev_with_tag() to use this function so that when a
1274 requested tag is not found, devices that were previously not checked
1275 are searched before searching all devices in the system.
1277 Added new functions to the blkid library, blkid_dev_set_search() and
1278 blkid_dev_has_tag().
1280 E2fsck's problem strings can now use @m and @n as abbrevations for
1281 "multiply-claimed" and "invalid", respectively.
1283 The e2fsprog.pot file now has an explanation of how the @-expansion
1284 and %-expansion works, and strings in e2fsck/problem.c which contain @
1285 characters now have comments in e2fsprogs.pot with the @-expansion to
1286 make life easier for translators.
1288 Fixed missing return values in the ext2fs library which could cause it
1289 to return random garbage in certain error conditions.
1291 Allow the current time to be overriden via the E2FSCK_TIME environment
1292 variable for use in regression tests.
1294 The test scrpit driver program now exits with a non-zero status if
1295 there any of its test that it ran failed.
1297 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
1300 Fixed "make check" so that it compiles correctly even when e2fsprogs'
1301 header files have not be installed in the system include directories.
1302 (Addresses Sourceforge Bug: #1180572)
1304 Fixed gcc -Wall nits.
1307 E2fsprogs 1.37 (March 21, 2005)
1308 ===============================
1310 Add support for checking the validity of Extended Attributes stored in
1313 Add support for dumping the contents of large inodes to debugfs,
1314 including the extended attributes stored in inodes.
1316 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1317 when we create a new inode we make sure that the extra information in
1318 the inode (any extra fields in a large inode and any ea-in-inode
1319 information) is initialized correctly. This can take place when
1320 mke2fs creates the root and lost+found directory, when e2fsck creates
1321 a new root inode or a new lost+found directory, and when the user uses
1322 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1323 create inode could inherit garbage (or old EA information) from a
1324 previously deleted inode.
1326 Fixed a bug in e2fsck so it would notice if a file with an extended
1327 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1330 Added support to filefrag to detect files which are using the new
1331 experimental file extents format, and use the non-ext2 algorithm in
1332 that case. Fixed a bug to avoid reporting a false discontinuity if
1333 there is one or more unallocated blocks at the beginning of a file.
1335 Duplicated a check for noticing whether or not the number of blocks
1336 (given a certain blocksize) is greater than 2**32 when the
1337 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1338 allows mke2fs to automatically use a larger blocksize when creating a
1339 filesystem on a very large device when run on systems that do not
1340 support BLKGETSIZE64.
1342 Fix the I18N build which was broken in e2fsprogs 1.36 because the
1343 build system had been switched to treat the .gmo files as shipped
1344 files (for backwards compatibility with systems that have older GNU
1345 I18N tools installed), but the gen_tarball.in script was still
1346 removing the .gmo files from the official source distribution.
1348 Fixed various Debian packaging issues --- see debian/changelog for
1349 details. (Addresses Debian Bugs ##296769, #299341)
1354 Added new functions to the e2p library which convert between a string
1355 and os_type: e2p_os2string() and e2p_string2os(), and used them to
1356 make the generated binaries more compact.
1358 Fixed a compile-time error on Darwin systems.
1360 Cleaned up the lib/ext2fs Makefile slightly.
1363 E2fsprogs 1.36 (February 4, 2005)
1364 =================================
1366 All of the patches that were applied to Fedore Core 3's
1367 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1368 lot of bug fixes first. Users of Fedora Core 3 are strongly
1369 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1371 Add support for filesystem with the online resizing via resize inode
1372 feature. Fixed numerous bugs from the Fedora patches. The Fedora
1373 patches also didn't bother to do any consistency checking on the
1374 resize inode, or add any tests to the regression test suite. The "-R
1375 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1376 being listed in mke2fs's usage message. All of these shortcomings
1377 have been corrected.
1379 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1380 program. In order to do this, the user must run the commands:
1382 debugfs -w /dev/hdXXX -R "features ^resize_inode"
1383 e2fsck -f /dev/hdXXX
1385 Optionally, the ext2prepare command can be used to re-enable online
1386 resizing after the filesystem has been fixed.
1388 The fsck program will now accept an optional filedescriptor argument
1389 to the -C option. (The Fedora version of this patch would sometimes
1390 cause fsck to ignore a parameter on fsck's command line in some rare
1393 Make sure e2fsprogs doesn't write garbage into the reserved portion of
1396 Make sure resize2fs releases the blocks belonging to the old inode
1397 table blocks when moving the inode table. (Addresses Debian Bug:
1400 Skip the r_resize_inode test if resize2fs is not compiled (due to
1401 configure --disable-resizer)
1403 E2fsck now checks the summary filesystem accounting information, and
1404 if any of the information is obviously wrong, it will force a full
1405 filesystem check. (Addresses Debian Bug #291571)
1407 Fix e2fsck to not complain when the resize_inode feature is enabled,
1408 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1411 Fix e2fsck to note delete symlinks that contain an extended attribute
1412 after the ext_attr feature flag has been cleared. (Addresses Red Hat
1415 Add new utility program, copy_sparse.c, which is very useful
1416 for dealing with large sparse files (such as e2image files).
1418 Add support for jnl_blocks[] for debugfs's set_super_value.
1420 Fix filefrag so that it works correctly with sparse files.
1422 Filefrag -v will print first and last blocks.
1424 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1427 Add mke2fs support so that it can support filesystems larger than 4TB
1428 automatically, by retrying with a 4k blocksize if the device size is
1429 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1432 Change blkid to test for NTFS first because Windows sometimes doesn't
1433 clear enough of the parition to confuse the probing routines into
1434 thinking the old filesystem type is still valid. (Addresses Debian
1437 Add support for swap partition label and uuid's in the blkid library.
1439 Add support to the blkid library to recognize Oracle ASM volumes.
1441 Make blkid -t display all devices that match the specified criteria,
1442 not just the first one, and work more consistently when the blkid
1443 cache file is not available or set to /dev/null. (Addresses Debian
1444 Bug #290530 and #292425)
1446 Badblocks will now correctly display block numbers greater than
1447 999,999,999 in its progress display.
1449 The tune2fs program will not allow the user from setting a ridiculous
1450 number of reserved blocks which would cause e2fsck to assume the
1451 superblock was corrupt. E2fsck's standards for what is a ridiculous
1452 number of reserved block has also been relaxed to 50% of the blocks in
1455 The blkid library will return vfat in preference to msdos, and ext3 in
1456 preference to ext2 (if the journalling flag is set) so that mount will
1457 do the right thing. (Addresses Debian bug #287455)
1459 Mke2fs will now use the -E option for extended options; the old -R
1460 (raid options) option is still accepted for backwards compatibility.
1461 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1463 Mke2fs will now accept a size in megabytes, gigabytes, and other units
1464 (via "32m" or "4g" on the command line) if the user finds this more
1465 convenient than specifying a block count.
1467 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1468 cache conherency problem.
1470 Debugfs now supports a new command, set_inode_field, which allows a
1471 user to manually set a specific inode field more conveniently, as well
1472 as set entries in the indirect block map.
1474 Debugfs's set_super_value command has been enhanced so that the user
1475 can set most superblock fields, including the date/time fields and
1476 some of the more newsly added superblock fields.
1478 E2fsprogs programs now accept an offset to be passed to the file
1479 specifiers, via the syntax: "/tmp/test.img?offset=1024".
1481 E2fsprogs programs will now accept blocksizes up to 65536; kernel
1482 support on the x86 doesn't exist for now, but it can be useful on
1483 other architectures with page sizes greater than 4k. There are 2.6
1484 kernel patches out there which enable this, but they are of this
1485 writing still experimental.
1487 The e2image command now takes the -s option which will scramble
1488 directory entries for raw image files.
1490 Fix a file descriptor leak in the filefrag program.
1492 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1495 Fix bug in debugfs where kill_file would lead to errors when deleting
1496 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1498 Fix bug in the blkid library when detecting the ocfs1 filesystem
1500 Remove obsolete EVMS 1.x and a.out DLL support.
1502 E2fsck will attempt to recover from a journal containing illegal blocks.
1504 Fixed two potential ordering constraint problems in e2fsck which might
1505 cause the filesystem to be corrupted if e2fsck is interrupted during a
1506 (extremely narrow) race window. Thanks to Junfeng Yang from the
1507 Stanford Metacompilation group for pointing this out.
1509 Fixed bug in e2fsck where it would not accurately detect whether or
1510 not the system is running on adaptor if the ACPI device representing
1511 the AC adapter didn't correspond to the what was used on IBM
1514 Change e2fsck to accept directories greater than 32MB.
1516 Fix e2fsck so that a checkinterval of zero disables a time-based check
1519 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
1520 to the PAGER environment variable. (Addresses Debian Bug #239547)
1522 Tune2fs will not mark rewrite the superblock if the feature bitmasks
1525 The debugfs program will set the filetype information when creating a
1528 Add debugfs -d option to use a separate source of data blocks when
1529 reading from an e2image file.
1531 Add e2image -I option which allows the e2image metadata to be
1532 installed into a filesystem.
1534 Fixed bug in the badblocks program which caused "done" to always
1535 appear in english even when a translation was available. (Addresses
1538 The blkid program has a new option -o which controls the output format
1539 of the blkid program; this is makes blkid more convenient to use in
1542 Fix a minor bug in uuid library, which was not using the full 14 bits
1543 of clock sequence when generating UUID's.
1545 Fix a Y8.8888K problem in the uuid library.
1547 Logsave now creates a new session id for itself to avoid getting
1548 killed by init whan transitioning between init levels.
1550 Change the licensing of the UUID library to be the 3-clause BSD-style
1551 license; this allows Apple to use the uuid library in Darwin.
1553 Add ocfs and ocfs2 probe support into the blkid library.
1555 Fix a memory and file descriptor leak in the blkid library.
1557 The blkid library will revalidate the device if the system time is
1558 earlier than last verification time of the device, since that
1559 indicates that the system time is probably nottrustworthy.
1561 The blkid library will override the default location of the blkid.tab
1562 file by the BLKID_FILE environment variable, if it is available.
1564 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
1566 Add various portability fixes for lame new versions of glibc, Darwin
1567 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
1568 Bugs #239934, #264630, #269044, #255589, #289133)
1570 Add support for Windows 9x/NT under Cygwin.
1572 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
1573 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
1575 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
1577 Update the rpm spec files so that it works better with Fedora core 2
1580 Fixed various Debian packaging issues (see debian/changelog). In
1581 particular, fixed the Debian initrd scripts. (#241183, #248050,
1588 Fixed various gcc -Wall warnings.
1590 The uuid library now has new functions uuid_unparse_upper() and
1591 uuid_unparse_lower() which forces the case of the hex digits to be
1592 upper case, or lower case.
1594 The build process has been speeded up by enhancing the subst program
1595 to update the modtime on the generated files even when the generated
1596 file hasn't changed.
1598 The uuid library now uses C99 stdint.h types instead of custom types.
1600 Updated config.guess and config.sub with newer versions from the FSF.
1602 Removed out of date .cvsignore files from the source distribution.
1604 The ext2fs_unlink() function will return an error if both the name and
1605 inode number are unspecified, to avoid doing something surprising
1606 (such as unconditionally deleting the first directory entry).
1607 Directory entries are now deleted by coalescing them with the previous
1608 directory entry if possible, to avoid directory fragmentation. This
1609 is not an issue with the e2fsprogs suite, but may be a problem for
1610 some of the users of libext2fs, such as e2tools.
1612 Add support for version numbers of the form "1.36-rc1".
1614 Fix build of mke2fs.static.
1616 Add basic ext2fs library support for large (EA in inode) inodes.
1618 The test_io mechanism can now abort after n reads or writes to a
1619 particular block. The block is specified by TEST_IO_BLOCK environment
1620 variable, and the read/write count by the TEST_IO_READ_ABORT and
1621 TEST_IO_WRITE_ABORT environment variables. The block data is now only
1622 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
1624 UUID_DEFINE() in the uuid library now creates a static variable, with
1625 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
1626 be used in header files.
1628 Add support for the install-strip and install-shlibs-strip targets, as
1629 suggested by the GNU coding guielines. "make install" no longer
1630 strips the binaries which are installed.
1632 Remove support for the --enable-old-bitops configure option which was
1633 only for very old sparc systems.
1635 Remove support for --enable-clear-htree; this was only needed during
1636 the early development of the htree patch.
1638 Use Linux-kernel-style makefile output so it is easier to see compiler
1641 Update gettext files to version 0.14.1.
1643 Update to use autoconf 2.5x.
1645 Improved support for compiling e2fsprogs under dietlibc.
1647 Make e2fsprogs portable to Solaris and FreeBSD systems.
1649 Add blkid_verify(), blkid_get_library_version(), and
1650 blkid_parse_version_string() functions to the blkid library.
1652 Add pkg-config files for e2fsprogs's libraries.
1654 Fix "make uninstall" to so that it removes everything that is installed.
1656 Add a configure --enable-maintainer-mode option which enables the
1657 makefile rules to rebuild the configure script from configure.in, and
1658 to reubuild the .gmo files in po directory.
1660 Drop the sparc assembly bitwise operations; it's less efficient
1661 than the GCC 3.4 compile code and triggers compiler warnings on
1662 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
1663 (Addresses Debian Bug #232326)
1666 E2fsprogs 1.35 (February 28, 2004)
1667 ==================================
1669 E2fsck has a new -k option, which in conjunction with the -c options,
1670 preserves the existing badblocks list.
1672 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
1674 E2fsprogs will now deal correctly with symlinks that contain
1675 extended attribute information, which can be created using SE Linux.
1676 (Addresses Debian Bug #232328)
1678 Remove a double longjump into an invalid stack frame bug in e2fsck.
1679 (This was during an abort sequence, which normally worked on Linux and
1680 caused a core dump on other operating systems.)
1682 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
1683 (the NLS library will replace "" with the .po header information).
1685 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
1686 dump due to a division by zero error. (Addresses Debian bug #207082)
1688 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
1689 when reconnecting a directory requires creating a lost+found
1690 directory. (Addresses Debian bug #219640).
1692 Fixed a bug where e2fsck would bomb out if a journal needed to be
1693 replayed when using an alternate superblock.
1695 E2fsck will give an extra grace period before actually forcing a check
1696 if the laptop is running on battery. The next time fsck runs while
1697 the system is on the AC mains, or after the grace period is exceeded,
1698 the filesystem will be checked. (Addresses Debian bug #205177)
1700 E2fsck will inform the user when there are 5 or fewer mounts before a
1701 filesystem check will be forced. (Addresses Debian bug #157194)
1703 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
1704 We now correctly handle the case where there is an overlap between a
1705 block group descriptor or a superblock and a bad block indirect block.
1706 In the case where the indirect block is corrupted, we now suggest
1709 Fix byte swap bugs in e2fsck that caused the journal backup location
1710 in the superblock and symlinks created by SE Linux to be cleared
1711 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
1713 E2fsck -c now replaces the current list of bad blocks with the ones
1716 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
1717 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
1719 Fix a potential bug in e2fsck which could cause it to core dump when
1720 trying to print the location of the backup superblock.
1722 Protect against a potential core dump in e2fsck when printing a
1723 message about backup superblocks.
1725 Add support for backing up the journal inode location in the
1726 superblock. E2fsck will automatically save the journal information in
1727 the superblock if it is not there already, and will use it if the
1728 journal inode appears to be corrupted. ext2fs_add_journal_inode()
1729 will also save the backup information, so that new filesystems created
1730 by mke2fs and filesystems that have journals added via tune2fs will
1731 also have journal location written to the superblock as well.
1732 Debugfs's logdump command has been enhanced so that it can use the
1733 journal information in the superblock.
1735 E2fsck will now update all superblocks when moving the journal inode.
1737 Shrink the size of the e2fsck executable by moving some initialized
1738 variables to the BSS segment.
1740 E2fsck will avoid printing the ^A and ^B characters which bracket the
1741 progress bar when stdout and stdin are a tty device instead of a pipe
1742 to another program. (Addresses Debian bug #204137)
1744 Debugfs's mkdir command will automatically expand the directory if
1745 necessary. (Addresses Debian Bug: #217892)
1747 Fixed a bug in debugfs so that copying a file from /dev/null uses the
1748 correct mode bits. (Addresses Debian Bug: #217456)
1750 If the environment variables DEBUFS_PAGER and PAGER are not set,
1751 debugfs now searches for the appropriate pager to use, beginning with
1752 /usr/bin/pager, and then falling back to 'more' and 'less'.
1753 (Addresses Debian bug #221977)
1755 Debugfs will now support 2.6 device numbers where the major or minor
1756 number may be larger than 255. (Addresses Sourceforge bug #865289)
1758 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
1760 Chattr now stops processing options when it sees '--'. (Addresses
1763 Fix regression tests so they work correctly when e2fsprogs is compiled
1764 with configure --disable-htree.
1766 Fix bug in uuid library when there is no network card and the library
1767 is generating a time-based uuid. The random MAC address was not
1768 correctly generated to be a multicast address.
1770 Add compile_et extensions from Heimdall that were missed the first time
1773 Fix bug in badblocks when using O_DIRECT; we need to make sure that
1774 we're reading from an offset which is page aligned. For read-only and
1775 read-write tests, we try to recover after an error so that we can
1776 continue reading on page-aligned boundaries. (Addresses Debian Bug
1779 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
1782 Updated and clarified various man pages. (Addresses Debian Bug
1783 #206845, #222606, #214920, #232406)
1785 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
1787 Fixed various Debian packaging issues (see debian/changelog).
1792 Fixed a build problem so that e2fsprogs would compile with the
1793 --enable-profile option to configure selected. (Addresses Sourceforge
1796 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
1797 Bugzilla Bug #112448)
1799 Centralize code which calculates the location of the superblock
1800 and block group descriptors so that it is in a single library routine.
1802 Added two new functions, ext2fs_file_open2() and
1803 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
1805 Fix compile_et to output the correct prototype for
1806 initialize_xxx_err_table_r() in the header file. (Addresses Debian
1809 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
1811 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
1812 present. This is for when we try stuffing an int into void * pointer.
1814 Fix type-punning which can cause gcc 3.x to miscompile code by getting
1815 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
1816 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
1817 **'. The EVMS code uses an ugly union approach since we don't want to
1818 modify the EVMS interfaces.
1820 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
1821 aid build process on systems can use invoke GNU make as "gmake".
1823 Added regression testing for mke2fs.
1825 Fixed gcc -Wall nitpicks.
1827 Fixed various compiler warnings.
1829 Add portability fixes for FreeBSD and for using fsctl under Darwin to
1830 support ext2 ioctl's.
1833 E2fsprogs 1.34 (July 25, 2003)
1834 ===============================
1836 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
1837 a tight loop while waiting for a child fsck to exit in some cases.
1838 This burns CPU times which slows down the low-level filesystem check.
1840 Added code to mke2fs to assure that the default block size for a
1841 filesystem is at least as big as the sector size of the device, if it
1844 Changed mke2fs and resize2fs to round the default size of a filesystem
1845 to be an even multiple of the VM pagesize in order to avoid a Linux
1846 kernel bug introduced when the storage of the buffer cache was moved
1847 into the page cache.
1849 Mke2fs will warn the user when creating a filesystem with journaling
1850 and a blocksize greater than 4096. (Addresses Debian bug #193773)
1852 Fixed a bug in resize2fs which caused it to fail on filesystems with a
1853 non-empty bad block list. Resize2fs now discards any blocks on the
1854 badblock list which are no longer part of the filesystem as the result
1855 of a filesystem shrink. (Note: this means that shrinking and then
1856 enlarging a filesystem is no longer a reversible operation;
1857 information about bad blocks in the part of the filesystem which is to
1858 be chopped off will be lost.)
1860 Changed resize2fs so the user can use prefixes to specify the units of
1861 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
1862 and to make the error and informational messages explicitly display
1863 the blocksize used by the filesystem, in order to avoid confusion.
1864 (Addresses Debian bug: #189814)
1866 Added a new debugfs command, dump_unused, which dumps the contents of
1867 all unused blocks to stdout. (Useful as an emergency try-to-find
1868 deleted data command.)
1870 Added a new debugfs command, imap, which prints the location of a
1871 specified inode in the inode table.
1873 Fixed a bug in the badblocks program which caused it to use one bit of
1874 randomness in its non-destructive read/write test, instead of using a
1875 full 8 bits of randomness.
1877 Added a new option (-t) to badblocks, which allows the user to control
1878 the test pattern(s) used when checking a disk.
1880 The blkid probe function now more correctly detects UDF filesystems.
1882 Fixed a bug in the blkid library which caused it to not update its
1883 cache if a filesystem changes from having a label to not having a
1886 Fixed a bug in the blkid library wihch could avoid an infinite loop
1887 in blkid_find_dev_with_tag() if /proc is not mounted and there the
1888 /etc/blkid.tab file has not yet been created.
1890 Fixed the badblocks program so that the destructive read/write test
1891 honors the -c option, and to use O_DIRECT when possible to avoid
1892 thrashing the system block buffer cache.
1894 Fixed various NLS issues.
1895 - Added Czech and Swedish translations
1896 - Removed testing NYC translation
1897 - Fixed NLS support for message abbrevations in e2fsck
1898 - Remove de-utf.po, since we shouldn't have two versions using different
1900 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
1901 simplify the statistics reporting in e2fsck.
1903 Changed configure.in so that its defaults for *BSD systems no longer
1904 build an fsck wrapper, and not to install in /usr/local by default.
1906 Fixed some minor spelling errors/typo's in e2fsck and the configure
1909 Fixed various Debian packaging issues (see debian/changelog).
1911 Updated and clarified man pages. (Addresses Debian Bug #195616)
1916 Fix gcc -Wall nitpicks.
1918 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
1919 NLS support by default. (Added partial workaround for gettext/Darwin
1920 incompatibility problems.)
1922 Added full MIT KRB5 and Himdall compaibility support to the com_err
1923 library and the compile_et program. (Addresses Debian bug #191900)
1925 Added the blkid_known_fstype() function to the blkid library, which
1926 returns true if it is passed a filesystem type which is recognized by
1927 the blkid probing functions.
1929 Improved the documentation for the blkid library.
1931 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
1932 returns the hardware sector size of a device, if it is available.
1934 Added a dependency in the blkid library's .so file to the uuid
1935 library, since the former uses the latter. (Addresses Debian bug
1938 Added --with-diet-libc and --disable-evms to the configure script.
1940 Fixed a minor memory leak in the badblocks program.
1942 Fixed a portability problem in tune2fs --- not all systems have strptime().
1944 Fixed a portability problem in debugfs with the use of getopt() more
1945 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
1948 Add support Windows support to ext2fs_get_device_size().
1950 Added (normally disabled) debugging code to the Unix I/O manager which
1951 causes it to disable all userspace caching if the NO_IO_CACHE is
1954 Changed the test I/O manager so it can always be linked into e2fsck,
1955 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
1956 configure script. The test I/O manager will only print any debugging
1957 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
1958 variables are set, which specifies which I/O operations are logged and
1959 a block number to watch, respectively. The log messages are sent to
1960 stderr by default, unless a filename is specified via the
1961 TEST_IO_LOGFILE environment variable.
1964 E2fsprogs 1.33 (April 21, 2003)
1965 ===============================
1967 Added a new utility program, logsave, which captures the output of a
1968 command in a log file, even if the containing directory hasn't been
1969 mounted yet (in which case the it saves the output in memory until it
1970 can write out the logfile). This is useful for capturing the
1971 output of fsck during the boot sequence.
1973 Fixed some portability problems that were causing problems under
1974 the Cygwin32 environment.
1976 Mke2fs now interprets a negative number to the -b option as a minimum
1979 Fixed a bug in mke2fs which was incorrectly checking the argument to
1980 the -g option if the default block size was used. (Addresses Debian
1983 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
1984 it can not find filesystem checkers for jfs, reseirfs, and xfs.
1986 E2fsck now updates the global free block and inode counters from the
1987 block group specific counters quietly. This is needed for an
1988 experimental patch which eliminates locking the entire filesystem when
1989 allocating blocks or inodes; if the filesystem is not unmounted
1990 cleanly, the global counts may not be accurate.
1992 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
1993 2.0 is not yet supported; this only pulled in the bug fixes: fixed
1994 possible hangs caused by bugs in calling waitpid, and not setting the
1995 pipe to non-blocking mode; also fixed a file descriptor leak; made
1996 sure all functions call log entry/exit functions.)
1998 Badblocks now flushes its output file as bad blocks are discovered.
2000 The uuid library is now more paranoid about assuming the correctness
2001 of the /dev/random device; it mixes in a stream of bytes from
2002 random/srandom, just in case.
2004 Update Debian files to reflect the fact that I am now the Debian
2005 maintainer of e2fsprogs. Other various Debian-specific packaging
2008 Move the source tarball generation functions from the top-level
2009 makefile to the util/gen-tarball script.
2011 Updated the Turkish .po translation file.
2013 Added Heimdal and MIT krb5 extensions to the com_err library to make
2014 it more compatible with com_err libraries from those distributions.
2016 Changed dumpe2fs to always display the superblock fields relating to
2017 the journalling and/or directory indexing feature even if those
2018 features are not enabled.
2020 Updated and clarify copyright statement vis-a-vis alpha releases of
2023 The ss library will now try to dynamically link to the readline
2024 library and use it if it is present in the system. This means that
2025 the debugfs program now has line editing and history features. The
2026 SS_READLINE_PATH environment variable is used to find a readline or
2027 readline-compatible library.
2029 E2fsck now finds most duplicate filenames (all when rebuilding all
2030 directories via the -D option) and offers to delete or rename
2031 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
2033 Fix bug in e2image. When writing out a raw image file, include data
2034 blocks from symlinks that do not store the symlink within the inode.
2036 Fix bug in resize2fs which incorrectly moved the block and inode
2037 bitmaps for sparse superblock filesystems and incorrectly marked
2038 blocks as in use. (Addresses Debian bug #174766)
2040 Added a new shared library, the blkid library, which efficiently
2041 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
2042 and UUID filesystem specifiers without needing to search all of the
2043 devices in the system. Instead, the device is looked up in a cache
2044 file, and then verified to make sure the blkid cache is correct.
2046 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
2047 the device name, using the blkid library. (Addresses Debian bugs
2050 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
2051 used for spaces in device labels.
2053 Removed 32-bit limitations for debugfs's dump command.
2055 If the user specifies a large number of inodes, Mke2fs will
2056 automatically adjust the number of blocks per group to find a valid
2057 set of filesystem parameters.
2059 Add workaround to detect broken MD devices where when some of the
2060 underlying devices are marked read-only, writes to the MD device are
2061 silently dropped. E2fsck will detect if there is an attempt to run
2062 the journal twice, and abort with an error if this is the case.
2063 (Addresses IBM Bugzilla bug #1226)
2065 E2fsck will print an error if more than one of the -p/-a, -n or -y
2066 options are specified.
2068 E2fsck will fix HTREE corruptions in preen mode, without stopping the
2069 boot process. This is needed because the 2.4 ext2 filesystem
2070 accidentally had the INDEX_FL backwards compatibility code removed.
2072 Mke2fs no longer creates filesystems with the dir_index flag set by
2073 default; the user has to specifically request it.
2075 Update and clarified various man pages. (Addresses Debian bugs
2076 #173612, #175233, #175113, and #170497, #185945, #188318)
2078 Created man page for the mk_cmds program (from the libss library).
2083 Fix various gcc -Wall nits.
2085 Fixed a lot of portability problems that caused e2fsprogs not to build
2086 successfully under Solaris and Apple/Darwin.
2088 Fixed a Makefile dependency to allow building e2fsprogs using parallel
2091 Changes to create a subset distribution which consists only of the
2092 et, ss, uuid, and blkid libraries. The configure script and top-level
2093 makefile were changed to support working with a subset distribution.
2095 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
2096 actually used, and might people who are looking for
2097 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
2099 Updated debian files to fix a number of Lintian warnings.
2101 Updated config.guess and config.sub with newer versions from the FSF.
2103 Removed unnecessary libraries from being linked into the fsck, lsattr,
2104 chattr, and blkid executables.
2106 E2fsprogs 1.32 (Nomvember 9, 2002)
2107 ==================================
2109 Fixed a bug in the Unix I/O routines which caused needless writebacks
2110 of clean blocks from the unix_io cache (they were erroneously marked
2111 as being dirty, so they were getting written back to disk before
2112 getting evicted from the disk cache). This was harmless, but it
2113 significantly slowed down e2fsck.
2115 Made some other minor optimizations to the Unix I/O routines to save a
2116 small amount of CPU time.
2118 Updated internationalization files.
2121 E2fsprogs 1.31 (Nomvember 8, 2002)
2122 ==================================
2124 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
2125 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
2126 handling for child process that die unexpectly. Add a hack to force
2127 mkfs to create filesystems that won't cause problems with hardware
2128 that has 2k or 4k minimum blocksize requirements. Read from child
2129 processes in non-blocking mode, so that the GUI continues to update.
2131 Fix e2fsck so that it returns the appropriate exit code when the root
2132 filesystem has been changed, so that system's rc scripts will be told that
2133 the system needs to be rebooted.
2135 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
2136 was set, some of the descriptor blocks that should have been written
2137 out were getting skipped.
2139 Changed e2fsck to force out changes to the backup copies of the
2140 superblock and block group descriptors when important changes are made
2141 to those data structures.
2143 Fix a bug where e2fsck could erroneously mark a filesystem as being
2144 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
2145 introduced in e2fsprogs 1.28.)
2147 If journal debuging is enabled using --enable-jbd-debug, the debugging
2148 level is now set via the E2FSCK_JBD_DEBUG environment variable.
2150 If byteswapping support is disabled using configure --disable-swapfs,
2151 skip the tests which depend on byte-swapping, so that "make check"
2154 Lshattr will now display the indexed directory flag. Also, some of
2155 the more esoteric compression flags are supressed unless compression
2156 support has been enabled.
2161 E2fsprogs 1.30 (October 31, 2002)
2162 =================================
2164 When resizing a filesystem, and inodes need to moved, resize2fs will
2165 update the inode's ctime field, and the mtime field of the containing
2166 directories, so that incremental backups using dump/restore will work
2169 In order to avoid spurious errors, e2fsck wil check the last
2170 superblock write time to determine whether or not it can safely use
2171 the LOW_DTIME checks to determine if there are inodes on the orphan
2172 inode linked list that had somehow gotten disconnected. (Addresses
2173 Sourceforge bug #620980)
2175 Partition in /proc/partitions that being with the string "lvm" are
2176 considered real partitions even if they do not end with a number.
2178 Fixed a bug in the the uuid generation function, where if /dev/urandom
2179 is not present, but /dev/random is, and there isn't sufficient
2180 entropy, the get_random_byte function could spin a loop forever.
2182 E2fsck, mke2fs, etc. will now reliably notice when image files are
2183 mounted using the loopback interface. (Addresses Sourceforge bug
2186 When flushing buffers (as is done by badblocks, for example) check to
2187 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
2188 FDFLUSH ioctl which causes the MD device driver which causes confusing
2189 syslog messages about obselete ioctl messages. (Addresses Sourceforge
2192 Debugfs's write command now checks to see if the destination filename
2193 exists before creating it. (Addresses Sourceforge bug #478195.)
2195 When installing man pages, search for compressed man pages using all
2196 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
2198 Fixed a bug in fsck where multiple filesystems specified on the
2199 command were not being checked in parallel due to a logic bug
2200 introduced to support the FSCK_MAX_INST environment variable.
2202 We have added a new superblock field, s_mkfs_time, which indicates
2203 when a filesystem was created. It is set via mke2fs, and printed out
2204 by dumpe2fs, but is not actually touched by the kernel.
2206 Dumpe2fs has been made more robust by not aborting if there is an
2207 error reading the block/inode bitmaps; instead it will still print out
2208 the location of the block/inode bitmaps and inode table.
2210 Add support for the an alternative block group descriptor layout which
2211 allows for on-line resizing without needing to prepare the filesystem
2212 in advance. (This is the incomat feature flag meta_bg.)
2214 Add support for storing default mount options in the superblock, so
2215 that the filesystem can be mounted with specific mount options without
2216 needing to specify them on the mount command line or in the /etc/fstab
2219 Add support for a new inode flag, which is to be used for indicating
2220 the top of directory hierarchies for the Orlov block allocator.
2222 Fix e2fsck so that if it creates the lost+found directory, it does so
2223 with the more apporpriate permissions of 0700. Also change
2224 mklost+found so that it also creates the directory 0700.
2226 Fixed format bug in e2fsck if NLS is in use.
2228 Add a German translation for e2fsprogs's NLS support.
2230 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
2231 the beginning of the inode table. This won't matter much, since if
2232 there is a bad block at the beginning of the inode table, the root
2233 directory won't be available. But at least e2fsck won't crash in this
2236 Fixed endian problems in the htree code for e2fsck and debugfs.
2238 When byte-swapping a filesystem on a PPC architecture, byte-swap the
2239 bitmaps since the historical big-endian ext2 variant had byte-swapped
2240 bitmaps, and the ext2fs library assumes this. This fixes the
2241 regression test suite on PPC machines.
2243 Fix e2image so that it handles a bad block in the inode table
2246 E2fsck now uses a more sophisticated algorithm to salvage corrupted
2247 directories that recovers more information in the corrupted directory
2250 E2fsck now performs additional consistency checks on indexed (HTREE)
2253 Fix bug where efsck might get confused about whether a completely
2254 empty directory block is an empty leaf block or an interior htree
2255 node. This could cause e2fsck to get confused into think that a valid
2256 indexed directory was corrupted.
2258 E2fsck no longer creates an empty directory entry at the end of a
2259 directory block when optimizing a directory. This would cause some
2260 earlier versions of the dxdir kernel code to corrupt the directory
2261 when attempting to split a node containing an empty directory entry.
2263 E2fsck could sometimes in rare circumstances leave the indexed flag
2264 set after a small directory was optimized by compressing it instead of
2265 indexing it. (This should never happen in real life, since
2266 directories that small wouldn't have been indexed, but better safe
2269 E2fsck now only updates the master superblock in all cases. This
2270 slightly shortens its run time.
2272 Ext2ed can deal with directory entries of length 0; previously it
2273 would get stuck in an infinite loop.
2275 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
2276 specifiers. (Sourceforge patch #613447)
2278 Badblocks will now work correctly on read-only devices such as
2279 CD-ROM's. (Sourceforge patch #600451)
2281 Updated and clarified man pages. (Addresses Debian bug #167108)
2284 E2fsprogs 1.29 (September 24, 2002)
2285 ===================================
2287 Fixed a bug in e2fsck which could corrupt a directory when optimizing
2288 it (via the -D option) or rebuiliding the hash tree index with a 1 in
2289 512 probability, due to a fence post error.
2291 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
2294 Mke2fs now enables the directory indexing flag by default. (Since
2295 this is a compatible feature flag, it's safe to do so.)
2297 Tune2fs will support setting the directory indexing feature flag. It
2298 will automatically set up the default hash algorithm and hash seed
2299 fields in the superblock.
2301 If the bone-headed user enters the root filesystem twice in
2302 /etc/fstab, the -R option which skips the root filesystem will skip
2303 all of them. (Addresses Debian bug #159423). Note! This is not a
2304 precedent for dealing intelligently with any other kind of doubled
2305 entry in /etc/fstab!
2311 Removed perror declaration in lib/et/internal.h. All modern systems
2312 can be expected to define perror() these days. Besides, the lib/et
2313 code wasn't using perror at all anyway. :-)
2316 E2fsprogs 1.28 (August 31, 2002)
2317 ================================
2319 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2320 for setting the htree flag is not included yet, although it can be
2321 manually turned on via the debugfs program.
2323 Clarified e2fsck error message which is printed when it cannot find
2324 sufficient contiguous block when relcating filesystem metadata.
2326 Added support for building an EVMS plugin module for ext2/3. This
2327 module is substantially the same as the EVMS module shipping with EVMS
2328 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
2329 for use with EVMS 1.0 (which did not include the ext2 plugin module),
2330 if the configure --enable-old-evms flag is given.
2332 Fsck will search through EVMS volumes when trying to resolve
2333 filesystem specifications such as LABEL=xxx or UUID=xxx.
2335 Added a new utility program, /sbin/findfs, which will return
2336 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2339 Update and clarified various man pages. (addresses Debian Bug #145044,
2340 #146437, #131350, #151990, #144621, #141938)
2342 If there are no filesystems specified on fsck's command line, fsck now
2343 treat that as if the -As options were given. Previously it would
2344 simply do nothing. (Addresses Debian Bug #153102)
2346 Mke2fs no longer treats a failure to be able to clear the MD signature
2347 at the end of the filesystem as a fatal error. (Addresses Debian Bug
2350 The e2p library functions (which are used by lsattr and chattr) now
2351 double check to make sure the file is a regular file or directory
2352 before attempting to use the ext2 ioctls. Some device drivers
2353 unfortunately respond to the ext2 ioctl's with unknown behaviour.
2354 (Addresses Debian Bug #152029).
2356 The extended attribute handling has been updated to correspond with
2357 the latest V2 bestbits ACL code.
2359 Fixed bug in e2fsck which caused it to not clear the dtime field when
2360 processing truncated inodes on the orphan list. This could cause data
2361 loss(!) if a filesystem is rebooted before a truncate has been
2364 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2365 algorithms. This makes e2fsck much faster in the case of severely
2366 corrupted filesystems where a large number of blocks are claimed by a
2367 large number of inodes. (Thanks to the 2.5 IDE device driver for
2368 inspiring this work.)
2370 Resize2fs has been significantly sped up when shrinking and expanding
2371 a filesystem by a very small number of blocks (for example, when EVMS
2372 is converting a partition to be an EVMS legacy volume).
2374 Added a new option to e2fsck, -D, which will optimize or compress all
2375 of the directories in the filesystem.
2377 E2fsck now catches SIGINT and SIGTERM to make sure it will can
2378 properly clean up and only exit at safe points. Fsck will pass
2379 SIGINT/SIGTERM to its child processes, and wait until they have all
2380 exited before it exits.
2382 The uuid parsing code in the uuid library now properly complains when
2383 an illegally formated uuid is presented to it. (Addresses Debian bug
2386 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2387 and 2.4.17, since the workaround can cause problems when using a 2.4
2388 kernel with an old version of glibc built with the 2.2 headers.
2390 Fixed a bug in mke2fs where it wasn't properly clearing the initial
2391 superblock used by other filesystems. (Addresses Debian bug #147256.)
2393 Added support for the synchronous directory feature written by Andrew
2396 The debugfs program can delete directories using the rmdir command.
2398 Add support for 8k and 16k filesystems (for systems with page sizes
2399 that are greater or equal to 8k or 16k, respectively). Note that
2400 these filesystems can not be mounted on x86 systems, or other systems
2401 with only 4k page sizes, due to limitations in the current Linux VM
2404 Resize2fs requires that the filesystem state be valid and have no
2405 errors; otherwise, e2fsck -f must be run first. (Previously it simply
2406 required that the last fsck time be greater than the last mount time.)
2408 Configure now defaults the man pages directory to /usr/share/man on
2411 E2fsck now offers to truncate inodes which contain too many blocks (so
2412 that i_blocks would overflow. Also fixed handling of large sparse
2415 E2fsck now more completely checks for symlink validity, including
2416 requiring NULL termination and length checks.
2418 E2fsck will offer to try forcing a disk write to remap a bad block
2419 after finding a read error when reading a filesystem metadata block.
2421 Fixed a bug in debugfs which caused the -b and -s options to crash
2422 debugfs, as well as breaking the testb, setb, and clearb functions.
2424 Added a bmap command to debugfs which calculates the logical to
2425 physical block mapping for a particular inode.
2427 Fixed a bug in code which checked to see if a device was mounted which
2428 sometimes (rarely) failed in the case of a plain file.
2430 Fixed a bug in resize2fs where when it reported an error, it would
2431 print a message erroneously indicating that the filesystem had been
2432 resized before it aborted.
2434 When resizing a plain file which is smaller than the requested size,
2435 resize2fs will attempt to extended the file so that programs like
2436 e2fsck will not complain that the file is too small.
2438 Resize2fs will print the actual new size of the filesystem when it is
2441 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2442 information on big-endian systems.
2448 Fixed collisions with C++ reserved words.
2450 Added portability fixes for building e2fsprogs on the HURD and AIX.
2452 Added the ext2ed program for creation of test cases. (ext2ed has many
2453 limitations and bugs which make it unsuitable for production use.)
2455 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2456 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2457 name_len field is byte swampped on big-endian machines, since in the
2458 V2 structure, name_len is a char field which is doesn't need to be
2459 byte swapped --- except if an old-style kernel had byte-swapped the
2460 name_len field as part of the V1 structure.
2463 E2fsprogs 1.27 (March 8, 2002)
2464 ==============================
2466 The warning messages for mke2fs now go to standard error.
2468 Fixed to make sure "make check" runs all of the test programs with
2469 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2471 The mke2fs program checks the boot sector for the BSD disk label, and
2472 avoids erasing it if it is there.
2474 Fixed a bug in e2fsck which caused it to core dump if the journal
2475 inode was missing when it was supposed to be there.
2477 E2fsck now prints ranges in pass 5 when printing deltas for the block
2480 Debugfs's "ls -l" command now will print out the file type information
2481 in the directory entry.
2483 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2484 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2486 Debugfs can now examine the experimental directory indexing
2489 Fixed bug in debugfs which caused it to core dump if modify_inode is
2490 called without an open filesystem.
2492 The debugfs lsdel command now runs its output through a pager first.
2494 When installing manual pages, remove the compressed manual pages first.
2496 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2498 Fix the 2.4 resource limitation workaround introduced in 1.26 which
2499 actually broke things on mips32, sparc32, and Alpha platforms.
2501 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2502 (which is required by the newer libintl libraries).
2507 Fixed various gcc -Wall complaints.
2509 Fixed a few memory leaks in the e2fsck journaling code, and in the
2510 ismounted code checking for a swap device.
2512 Add new inode I/O abstraction interface which exports an inode as
2515 Exported ext2_file_flush as a public interface.
2517 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
2519 Lots of small random portability fixes to make e2fsprogs build under
2520 AIX --- even without the 5L compatibility toolkit, and even using the
2521 uber-crippled AIX native C compiler.
2524 E2fsprogs 1.26 (February 3, 2002)
2525 =================================
2527 Dumpe2fs will keep going now if the bad block inode can't be read.
2528 (Previously it stopped with a fatal error.)
2530 E2fsck will now give an opportunity to run the journal even if the
2531 recovery flag is not set. This is the default behaviour if e2fsck is
2532 using a backup superblock, since the needs_recovery flag will never be
2533 set in the backup superblock copies.
2535 E2fsck now automatically finds the backup superblock/group descriptors
2536 even when the primary superblock is completely destroyed for 2k and 4k
2537 filesystems. (Previously it just guessed/assumed that we were dealing
2538 with a 1k filesystem in that case, and users had to manually specify
2539 the backup superblock number.)
2541 Fixed a bug in e2fsck where it dereferences a null pointer when there
2542 is a problem opening a filesystem in preen mode.
2544 E2fsck now handles external journals correctly; previously it trashed
2545 the external journal device if the journal needed to be replayed.
2547 Work around ulimit incompatibility problem caused by recent 2.4
2548 kernels; the unix IO module will automatically try to set any resource
2549 limits to be infinite on startup.
2551 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
2552 bitmap if it wasn't present and the blocksize was 2k or 4k.
2553 (Addresses Debian Bug #116975)
2555 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
2556 clearing the new V2 fields if they do not make sense or if the ext3
2557 superblock is version 1 superblock.
2559 E2fsck will automatically relocate the ext3 journal from a visible
2560 file (i.e., /.journal) to an hidden inode if the filesystem has been
2561 opened read/write. This allows the users to add a journal while the
2562 filesystem is mounted, but the next time the system is rebooted, the
2563 journal file will disappear. This avoids problems with backups,
2564 stupid operators with superuser bits, etc.
2566 Fix a bug in fsck where it would not support a filesystem type of
2567 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
2569 Fsck now supports fstab entries of the form "ext3,ext2". It will also
2570 automatically identify reiserfs filesystems.
2572 The number of processes spawned by fsck can now be limited using the
2573 FSCK_MAX_INST environment variable.
2575 Fsck now searchs the LVM proc hierarchy to find logical volumes which
2576 should be searched for UUID and label information.
2578 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
2579 limit if at all possible, when opening a block device. (The filesize
2580 limit shouldn't be applied against writes to a block device.)
2582 In mke2fs and e2fsck, specifying the -c option twice will now do
2583 a read/write test on the disk. Update the man pages to encourage
2584 using the -c option, and to discouraging running badblocks separately,
2585 since users tend to forget to set the blocksize when running
2588 Mke2fs now automatically clears the immutable attribute on a
2589 pre-existing .journal file left over from a previous failed attempt to
2590 add a journal to an alreadyy-mounted filesystem.
2592 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
2595 Mke2fs now creates the lost+found directory with permissions of 0700,
2596 so that files that had previously lived in protected directory are
2597 safe if they get dropped in lost+found and the system administrator
2598 doesn't deal with immediately. (Addresses Debian #bug 118443)
2600 Mke2fs and e2fsck (and all programs that use the
2601 ext2fs_check_if_mounted function) will now properly identify that a
2602 device is mounted, even in cases where devfs has confused things with
2603 multiple devices names with the same identity, or if a dim-witted
2604 system administrator has done something stupid like creating device
2605 file aliases in their home directory. Also now checks for swap devices
2606 by using /proc/swaps. (Addresses Debian bug #106622)
2608 Added a new option (-T) to tune2fs which sets the time a filesystem
2611 Speed up e2image when creating sparse raw image files by optimizing
2612 away excess lseek() system calls.
2614 Fix support of large (> 2GB) files when used as a filesystem in
2615 mke2fs, tune2fs, debugfs, and findsuper.
2617 Debugfs's stat and icheck commands now properly deals with large (>
2620 Debugfs's set_super_value command now prints out the list of valid
2621 superblock fields which can be set using the command.
2623 Debugfs's rm and kill_file command now updates the superblock free block
2624 and inode counts, thus keeping the filesystem consistent.
2626 Debugfs's lsdel command now takes an optional argument which allows
2627 the user to only see the most recently deleted files.
2629 A new command (undel) was added to debugfs which automates
2630 undeleting a deleted inode and linking it back to a directory.
2632 Debugfs's ls command now takes a new option, -d, which lists
2633 deleted directory entries.
2635 Debugfs's testb, freeb, setb, and find_free_block commands now take an
2636 optional count argument.
2638 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
2639 be used to signal that a particular inode should not be eligible for
2640 tail-merging --- this is needed for programs like LILO.
2642 The findsuper (an unreleased, uninstalled utility program) has been
2643 improved to add extra validity checks and to add a progress meter.
2644 (It is still an unsupported program; the officially supported way to
2645 recover from a trashed partition table is to use gpart; findsuper is
2646 for wizards only. :-)
2648 Debugfs was fixed to compile with "configure --disable-swapfs".
2650 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
2652 Added new translation file for Turkish.
2657 Fix general gcc -Wall complaints.
2659 E2fsprogs (mostly) works with the dietlibc.
2661 The programming texinfo file has been expanded to include description
2662 of additional libext2fs functions. (Still not compeltely done, but a
2663 lot of the more important functions have been documented.)
2665 Added a umask structure to struct_ext2_filsys, which currently only
2666 modifies the behaviour of ext2fs_mkdir(), but if we add any file
2667 creation functions to libext2fs, we should also make sure they respect
2670 The build-rpm script was fixed to be a bit more safe.
2672 The tests' Makefile now has a way of automating test case creation
2673 for e2fsck, using "make testnew".
2675 Created a new function, ext2fs_dir_iterate2 which passes more
2676 information to the callback function (identical to the one used by
2677 ext2fs_dblist_dir_iterate). The directory iterator functions take a
2678 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
2679 directory entries. If the directory entry is deleted, the callback
2680 function will be called with the entry paraemter set to
2681 DIRENT_DELETED_FILE.
2683 Added new functions, ext2fs_inode_alloc_stats and
2684 ext2fs_block_alloc_stats, which takes updates block/inode allocation
2685 statistics in the bitmaps, block group descriptors, and superblock
2686 when inodes or blocks are allocated or deallocated.
2689 E2fsprogs 1.25 (September 20, 2001)
2690 ===================================
2692 This is primarily a bug-fix release; no new features were added, but
2693 there are a number of embarassing bug fixes and cleanups applied.
2695 Fix a bug mke2fs which causes stack garbage to be written to disk when
2696 zapping disk sectors. (This bug could cause mke2fs to core dump for
2697 some kernels, I suspect with security enhancement patches.)
2699 Remove unneeded #include of <linux/config.h> which was breaking
2700 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
2702 Updated tune2fs man page to reflect the fact that adding or removing a
2703 journal doesn't require running e2fsck.
2705 Remove use of AC_REQUIRE from autoconf which had been used to prevent
2706 AC_CANONICAL_HOST from being called twice; unfortunately this causes
2707 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
2708 used outside of autoconf macros. Fortunately, it doesn't seem to be
2709 necessary any more, anyway.
2711 E2fsck will now not fall back to an alternate superblock if the user
2712 specifies the superblock location explicitly on the command-line.
2713 This allows easier recovery from a situation where the primary
2714 superblock and block groups are slightly corrupted, but the backup
2715 superblocks are completely broken.
2717 Fix problem which caused compile_et and mk_cmds to blow up if
2718 e2fsprogs was in a directory with a pathname that contained spaces.
2720 We are now more paranoid about checking the entry in /etc/mtab to make
2721 sure the filesystem is really mounted, since some broken distributions
2722 (read: Slackware) don't initialize /etc/mtab before checking non-root
2723 filesystems. (Slackware also doesn't check the root filesystem
2724 separately, and reboot if the root filesystem had changes applied to
2725 it, which is dangerous and broken, but there's nothing I can do about
2728 Make UUID library C++ friendly by adding appropriate extern "C"
2729 declarations and using const in the function declarations.
2731 Fix up the com_err texinfo file so that it can product a valid info
2732 file (previously, it could only be used to generate paper
2733 documentation using texinfo.tex).
2736 E2fsprogs 1.24a (September 2, 2001)
2737 ===================================
2739 Fix brown-paper bug in mke2fs which caused it to segfault when
2740 printing the version string.
2743 E2fsprogs 1.24 (August 30, 2001)
2744 ================================
2746 Revert the BLKGETSIZE64 support, since for some distributions, this
2747 ioctl has been used by an unofficial kernel patch to update the last
2748 sector on the disk, and this was causing disk corruption problems as a
2751 Mke2fs is now more careful about zapping swap space signatures and
2752 other filesystem/raid superblock magic values so that programs like
2753 mount who try to use hueristics to determine the filesystem type of a
2754 partition are less likely to be confused.
2756 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
2757 regular file (since Andreas Dilger's on-line resizing tools will set
2760 Fixed some minor texinfo, man pages nits for spelling errors,
2761 texinfo warnings, etc. (Addresses Debian bug #110621.)
2763 E2fsprogs program no longer print the filesystem version number
2764 (i.e. 0.5b), since it only confuses people and doesn't serve any real
2767 E2fsck will once again compile under libc5, since it will supply its
2768 own version of strnlen if necesssary.
2770 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
2771 when specifying the external journal device. tune2fs will also search
2772 devices looking for the externla journal debice when removing.
2774 E2fsprogs 1.23 (August 15, 2001)
2775 ================================
2777 Add initial support for extended attributes (EA); e2fsck will
2778 correctly handle a filesystem with EA's and check the EA blocks for
2781 E2fsck's symlink sanity checking has been cleaned up. It now checks
2782 the i_size value of fast symlinks, and checks for immutable flags
2783 being set of symlinks, etc.
2785 E2fsck now offers to clear inodes which are special files that have a
2786 non-zero i_blocks or i_size field. (The i_size field check was in the
2787 previous version of the code, but due to a bug it didn't offer to
2788 clear the inode unless i_size and i_size_high were both non-zero.)
2790 E2image can now create "raw" image files, which only contain the
2791 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
2792 debugfs, etc., can be run directly on the raw image file.
2794 Add support for the 64-bit block device patches.
2796 Fixed bugs in creating external journals with a 1k blocksize.
2798 Add initial support for external journals (so long as the external
2799 journal only supports a single filesystem) in e2fsck.
2801 Remove requirement for needing to run fsck on a filesystem after
2802 removing a journal (either internal or external).
2804 The man pages now document how to create and manage external journals.
2806 Speed up the check of an ext3 filesystems by avoiding a needless flush
2807 of all of the superblock and block group descriptors.
2809 Speed up creating an internal journal using tune2fs in the case where
2810 the filesystem has a lot blocks already allocated.
2812 Tune2fs has been fixed to make sure that only error messages go to
2813 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
2815 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
2816 now not set the sparse_super feature. (Addresses Debian bug #108165)
2818 Add support in fsck for the filesystem type "auto".
2820 Fsck -A will not try to interpret device names for filesystems which
2821 have a pass number is 0. (Addresses Debian bug #106696).
2823 Fsck prints a warning message if now valid filesystems are passed to
2824 it. (Addresses Debian Bug #107458.)
2826 E2fsck now gives an explicit warning if there filesystem still has
2827 errors at the end of the run. (Addresses Debian bug #104502)
2829 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
2830 reflects an error. E2fsck will also not run the orphan list if the
2831 filesystem contains errors, since the orphan list might be corrupted.
2833 E2fsck now prints the number of large files when given the -v option.
2835 Fixed minor memory leaks in e2fsck.
2837 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
2840 E2fsprogs 1.22 (June 22, 2001)
2841 ==============================
2843 Fixed a bug in e2fsck's handling of orphan inodes which are special
2844 files (i.e., block/character device files, named FIFO's, etc.).
2846 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
2847 tune2fs to fail at adding a journal to a mounted filesystem.
2849 Fixed a few big-endian bugs in e2fsprogs
2850 * The directory block functions were accidentally reporting
2851 some directories as corrupted when they weren't.
2852 * If e2fsprogs is compiled --disable-swapfs, the C language
2853 equivalents weren't being included for big-endian platforms.
2854 (Fixes Debian bug #101686).
2856 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
2861 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
2862 ioctls, and allow them to be defined for non-i386 platforms.
2864 The uuid.h header file is now protected against multiple inclusions.
2866 E2fsprogs is now being developed using BitKeeper. Changed the test
2867 scripts to deal with BK's stripping CR characgters from text files,
2868 and changed the top-level Makefile.in to avoid including BitKeeper
2869 files when generating the source tarball.
2872 E2fsprogs 1.21 (June 15, 2001)
2873 ==============================
2875 Added new configure flags which allow a subset e2fsprogs to be built;
2876 this is most useful for boot floopies, since the resulting shared
2877 libraries and programs are slimmed down by removing features that
2878 aren't necessary for a boot floppy. The new flags that were added
2879 are: --disable-swapfs, which removes support for byte swapping old
2880 legacy PPC/68k filesystems, --disable-debugfs, which removes support
2881 for debugfs from the libext2fs library, --disable-imager, which
2882 removes support for the e2image program, and --disable-resizer, which
2883 removes support for resize2fs.
2885 E2fsck now prints the number of mounts or days elapsed since the last
2886 check when e2fsck is forced to check an otherwise clean filesystem.
2888 Tune2fs now prints an informative message about how often a filesystem
2889 will be checked when adding a journal to the filesystem, to remind the
2890 user that he/she may want to adjust those parameters using tune2fs
2893 Worked around hurd brain-damage which causes e2fsck to sometimes
2894 believe a filesystem is the root filesystem based on device numbers
2895 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
2898 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
2899 erroneous error with the -F option was specified.
2901 Fixed a ext3 recovery bug in the revoke handling; synchronized with
2904 Fixed two bugs in e2fsck's handling of dup block handling, dealing
2905 with relatively uncommon edge cases: a directory with an indirect
2906 block which is claimed by another file, and when the last inode in the
2907 filesystem has blocks claimed by another file.
2909 E2fsck now checks to see if the i_size field of a fast symlink is too
2910 big, and offers to clear the symlink if so.
2912 E2fsck now checks to see if i_size_high of special files is non-zero,
2913 and offers to clear i_size_high.
2915 Fix e2fsck's handling of incompatible journal flags so that the user
2916 has chance to abort, and then has the option to clear out the journal
2917 entirely. (Addresses Debian bug #98527.)
2919 Fixed a bug in fsck which could cause it to core dump if a mix of
2920 standard and non-standard device names are used in /etc/fstab.
2921 (Debian bug #100559)
2923 Fixed a bug in debugfs which caused read errors when copying a file to
2926 The debugfs set_super_value command can now modify the s_lastcheck field.
2928 Fixed a bug in lsattr and chattr which was accidentally introduced in
2929 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
2930 directories correctly because the change modified the layout of struct
2931 dirent to be incompatible with the libe2p shared library.
2933 Cleaned up the mke2fs manual page and included a discussion about why
2934 it's good to periodically check the filesystem even when journaling is
2940 Fix general gcc -Wall complaints.
2942 The types needed by the ext2 header files are now provided by
2943 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
2945 Integers are now preferred to longs when trying to find a 32-bit type
2946 in ext2_types.h. Also, if linux/types.h has already been defined,
2947 don't try to redefine the types.
2949 Fixed make depend script so that it automatically corrects the
2950 pathname cleanups performed by make -M, so I don't have to fix them up
2953 Fixed the d_loaddump test case to be more robust, and not depend on
2956 Removed debugfs's dependence on pread(), which was accidentally
2957 intrudced in e2fsprogs 1.20
2959 Fixed a performance bug in the libext2fs's icount routine; the size
2960 estimate of the icount array was incorrectly being calculated.
2962 Removed use of the badblocks compatibility functions in the e2fsprogs
2965 Added paranoia code which protects against strange cases where /etc
2966 isn't on the root filesystem, or if /etc/mtab doesn't exist.
2968 The header file ext2_types.h is now installed.
2970 Autoconf is used to determine when we are on big-endian machines,
2971 instead of doing run-time tests, to save a few bytes of code.
2973 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
2974 functions are no longer inline functions, which saves space and
2975 doesn't really cost any real performance.
2977 The ext2fs library no longer depends on the e2p library. (What need
2978 there was of it --- namely, fsetflags, was coded in-line).
2980 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
2981 when the user is stupid and tries compiling the package using "make
2984 Miscellaneous code cleanups:
2985 * Added missing files from Makefile.in's SRCS file, so that
2986 their dependencies would be properly calculated.
2987 * Removed redundant code
2988 * Fixed comments in code
2989 * Removed no-longer unneeded argsused #pragma.
2992 E2fsprogs 1.20 (May 20, 2001)
2993 =============================
2995 Add support for replaying the ext3 journal purely in user mode,
2996 including handling the orphaned inode list. Used code contributed by
2997 Andreas Dilger, with bug fixes and the orphaned inode handling done
3000 The mke2fs and tune2fs programs can create or modify a filesystem to
3001 include an ext3 journal. Tune2fs also can be used to remove an ext3
3002 journal from a filesystem.
3004 E2fsck will now check for the existence of a linked list of orphan
3005 inodes in the superblock, and clear those inodes before starting the
3006 rest of the filesystem check (but after the journal playback).
3008 E2fsck now validates the file descriptor passed to the -C option,
3009 which saves against the completion bar getting written to an
3010 unexpected location, such as the disk being checked. (Debian
3011 bug/wishlist #55220)
3013 E2fsck will now bump the filesystem revision number from zero to one
3014 if any of the compatibility bits are set.
3016 Fixed a bug where a badly corrupted directory on a big endian system
3017 could cause e2fsck to die with a bus error. The
3018 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
3019 the ext2 library now does alignment sanity checks on the rec_len field
3020 of the directory entry before using it.
3022 The ext2 library has been enhanced to make tune2fs safe to run on
3023 mounted filesystems. (Users could usually get away with using tune2fs
3024 on mounted filesystems before, but with the advent of ext3 and
3025 journaling, it became important to make tune2fs was *really* safe for
3026 use even when the filesystem being modified is mounted.) E2label is
3027 now implemented by tune2fs using an argv[0] dispatch, so that e2label
3028 is also now safe for use on mounted filesystems.
3030 Added a new program, e2image, which creates a backup of critical ext2
3031 filesystem data structures. The generated image file can be examined
3032 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
3033 the image file to help recover very badly damaged filesystems.
3035 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
3036 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
3037 large file when deciding whether or not the filesystem has large files.
3039 Fixed lsattr and chattr so that they work correctly on large files.
3040 (Fixes Debian bug #72690.)
3042 Removed limitation in get_device_size() which imposed a one terrabyte
3043 filesystem limitation. (Most 2.2 kernels still have a signed int
3044 problem which cause 1 TB block device limitation. Fortunately, the
3045 kernel patches to fix this are much easier than fixing the 2TB
3046 limitation in the kernel. :-)
3048 A max_mount_count of zero is now treated as if no mount count were
3049 set. (Previously, no mount count was indicated by using -1, and a
3050 mount count of zero caused e2fsck to always be run.)
3052 Mke2fs supports two new filesystem types largefile and largefile4.
3054 Mke2fs now adds some randomness in s_max_mount_count so that multiple
3055 filesystems won't be all checked at the same time under normal
3058 Fixed bug in the progress bar printing code which could cause e2fsck
3059 to core dump on an illegal filesystem.
3061 Fixed bug in fsck which could allow more than one instance of e2fsck
3062 to be printing a progress bar. (Debian bug #65267)
3064 Fsck using a UUID or a LABEL specifier will work even if devfs is
3065 compiled into the kernel and not mounted. If the pathnames in
3066 /proc/partitions are incorrect, fsck will search /dev for the correct
3067 device (using the new ext2fs_find_block_device library function).
3068 Fsck now also checks the RAID devices first so that they are properly
3069 found when they are in use. Support has also been added to support
3070 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
3072 Fixed a bug in fsck which caused it not deal properly with 16
3073 byte long filesystem labels.
3075 Fsck's -t option has been made a lot more flexible. The semantics for
3076 what happens if a comma-separated list to fsck has been regularized,
3077 and it is now possible to filter what filesystems will get checked
3078 based what is in the filesystem's fstab entry's option field. (Debian
3081 The dumpe2fs program can now print out the group description
3082 information in hex, and also prints the location of the superblock and
3083 block group descriptor for those block groups that have them.
3085 Mke2fs now clears the ext2 superblock before it starts creating a
3086 filesystem, so that the superblock magic number is only written if the
3087 filesystem creation process successfully completes.
3089 The debugfs program's stat command now pretty-prints the blocks used
3090 by an inode so that it's more compact and informative.
3092 The debugfs stats command now uses the same libe2p code (which is used
3093 by dumpe2fs) to print the superblock header information. This is more
3094 complete, and it avoids a bit of code duplication.
3096 Added a new debugfs command, set_super_value (ssv) which allows the
3097 user to set arbitrary superblock fields.
3099 Debugfs was extended to support inode numbers in hex (by prefixing
3100 them with 0x), and so that modify_inode can set the inode generation
3101 number. Also, there is now a new function command called logdump
3102 which will dump an ext3 journal.
3104 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
3107 Debugfs's dump command now stops immediately upon reporting a disk
3108 read error. (Fixed a bug in ext2fs_file_read library routine which
3109 caused debugfs not to stop.) (Debian bug #79163)
3111 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
3112 checked before /etc/mtab is used, since /proc/mounts is more likely to
3115 Added portability fixes for Solaris and Linux/ia64.
3117 Various manual pages were clarified and cleaned up. (Fixed debian
3118 bugs #63442, #67446, and #87216)
3124 The e2fsck message printer now supports %Iu and %Ig, which will print
3125 out the inode's user and group owners, respectively.
3127 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
3128 that no longer dependent on the system having the correct version of
3129 the kernel header files.
3131 Added a new function to libext2, ext2fs_find_block_device(), which
3132 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
3133 device given its device number.
3135 Added a new function to libext2, ext2fs_sync_device, which centralizes
3136 all of the places which might try to use the BLKFLSBUF or FDFLUSH
3137 ioctls (and usually failing to define them since the system header
3138 files don't usually do this for us, and we're trying to avoid usage of
3139 kernel include files now).
3141 Added new utility programs in tests/progs: random_exercise and
3142 hold_inode. They aren't built by default; they're useful for
3143 exercising ext3 filesystem code.
3145 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
3146 the filesystem close functions to only update the superblock, and to
3147 not touch the block group descriptors. Needed by tune2fs when
3148 modifying a mounted filesystem.
3150 Got rid of struct ext2fs_sb and replaced it with the standard struct
3151 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
3152 source (but not binary) compatibility of some users of the ext2
3153 library. Those applications should just simply do a global search and
3154 replace of struct ext2fs_sb with struct ext2_super_block, and include
3155 the new header file <ext2fs/ext2_fs.h> which defines it.
3157 The ino_t type has been renamed ext2_ino_t to protect applications
3158 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
3159 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
3160 unexpected ABI change.
3162 The Makefiles have been reworked so that "make check" can be run from
3163 the top-level Makefile.
3165 Fix general gcc -Wall complaints and removed dead code.
3167 Remove use of NOARGS, because we assume everyone does ANSI C these
3170 Added build-rpm script from sct.
3172 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
3175 New function ext2fs_flush_icache which must be called if the
3176 application program modifies the inode table blocks without going
3177 through ext2fs_write_inode() interface.
3179 New ext2fs_check_mount_point() function, which will return the mount
3180 point of a device if mounted.
3182 The io_channel abstraction now has an optional interface,
3183 io_channel_write_range, which allows specific byte ranges to be
3186 The unix_io IO channel now supports write-through caching, so that
3187 journal creation is more efficient.
3189 Added x86 assembly language routines to support byte swapping, to
3190 reduce executable size.
3192 Fixed bug in the utility program subst so that it's possible to
3193 replace a substitution variable with a zero-length string.
3195 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
3196 slipped into some of the problem number.
3198 E2fsprogs 1.19 (July 13, 2000)
3199 ==============================
3201 Release the resize2fs program since the timeout before it could
3202 be released under the GPL has finally expired.
3204 Add experimental support needed for the ext2 compression patches.
3205 This requires compiling e2fsprogs with the --enable-compression flag
3206 to the configure script.
3208 Added ext3 journalling support. E2fsck will run the journal (if
3209 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
3210 installed as a symlink to e2fsck. Fsck has been taught about ext3,
3211 and treats it the same as ext2 in terms of the progress bar logic.
3212 Dumpe2fs will display the superblock journaling information if the
3213 filesystem has a journal. The ext2 library will now permit opening an
3214 ext3 filesystem with the recovery flag set. This is necessary for
3215 on-line dump's to work correctly, but there may be issues with this
3216 working well since ext3 is much less agressive about syncing blocks to
3217 the filesystem, since they're safe on the journal.
3219 Tune2fs and e2fsck have been changed to allow the mount_count check to
3220 be disabled by setting max_mount_count to -1. (This was already
3221 supported by the kernel.)
3223 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
3224 are used for ext3 as well.
3226 Added internationalization support for e2fsprogs; must be enabled
3227 by passing --enable-nls to configure.
3229 Always use the provided ext2fs header files to insulate ourselves from
3230 kernel version changes. Which include files are used by e2fsprogs
3231 have also been cleaned up to improve portability.
3233 Limit the number of times that e2fsck updates the progress bar so that
3234 people who are booting using a 9600 baud console don't get swampped by
3237 Improved the loop detection algorithm in e2sck's pass #3 so that it is
3238 much, much faster for large filesystems with a large number of
3241 The memory footprint for e2fsck is now slightly smaller than before.
3243 E2fsck now checks if special devices have a non-zero size, and offers
3244 to clear the size field if it finds such an inode.
3246 E2fsck now checks if special devices have the append-only flag set,
3247 and offers to clear the inode.
3249 E2fsck now properly handles some "should never fail" cases during a
3250 bitmap copy in pass5.
3252 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
3254 E2fsck now calculates the correct location of the backup superblock in
3255 the case of filesystem blocksizes > 1k.
3257 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
3258 which normally didn't cause problems under most filesystem parameters,
3259 but could cause a valid superblock to be rejected in extreme cases.
3260 Other checks for validating superblock values were made more
3263 Added non-destructive write testing to the badblocks program, courtesy
3264 of David Beattie. The badblocks also now has an option to input the
3265 current set of bad blocks, so that known bad blocks are skipped to
3266 speed up the badblocks test. There is also a persistent rescan
3267 feature which causes badblocks to run until it has completed some
3268 number of passes without discovering any new bad blocks.
3270 Badblocks now checks to see if the device is mounted and refuses to do
3271 the tests involving writing to the device if it is mounted. Also,
3272 badblocks now allows the number of blocks to be checked to be
3273 defaulted to the size of the partition.
3275 Fixed a bug in fsck which didn't allow non-root users to be able to
3276 check filesystems if there were any LABEL= or UUID= entries in
3279 The Hurd doesn't support the filetype filesystem feature. The mke2fs
3280 program now makes sure that for the Hurd, the filestype feature is
3281 turned off. E2fsck will check to see if the filetype feature is
3282 turned on for Hurd filesystems, and offer to turn off the feature.
3284 Mke2fs now has a safety check to make sure the number of blocks do not
3285 exceed 32 bits even on a 64 bit platform.
3287 Really fixed a bug in fsck to allow "fsck -As" to run interactive
3288 fsck's. (For those people who like to do interactive fsck's in the
3291 Debugfs has a few new features: the rdump command, which will do a
3292 recursive dump of a directory and all of its contents, and the lcd
3293 command which does a local chdir (much like the ftp command of the
3294 same name). In addition, the debugfs program and the open_filesystem
3295 command now takes three new options: -b and -s, which allows the
3296 blocksize and superblock location to be specified, and the -c option
3297 which is used in catastrophic situations where the block group
3298 descriptors are corrupt. If the -c option is specified, debugfs will
3299 skip trying to read in the block and inode bitmaps.
3301 Debufs's lsdel command was fixed to handle bad blocks in the inode
3304 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
3307 General improvements in error messages
3309 - Mke2fs prints a sane error message if the partition size is zero
3310 (usually because the partition table wasn't reread by the
3311 kernel due to the partition being busy), instead of "invalid
3312 argument passed to ext2 library while initializing superblock".
3314 - Fsck now prints more self-explanatory message if an invalid UUID=
3315 or LABEL= specification is passed to it.
3317 UUID library changed to use the LGPL.
3319 Fixed a bug in the UUID library where very rapid calls to the
3320 time-based UUID generator could cause duplicate UUID's to be returned.
3321 This was not a problem for e2fsprogs, but it could be a problem for
3322 other users of the library.
3324 Make the UUID library more robust in the face of missing or an
3325 improper /dev/urandom or /dev/random files.
3327 Added some random portability fixes for Solaris.
3329 Some minor man page updates.
3331 Fixed a memory leak in the ss library.
3337 We now try to use lseek64 and open64 from the LFS if possible.
3339 The 3rd parameter in e2p's print_flags is now a flags word, instead of
3342 The mark and unmark bitmap functions now return the previous state of
3343 the bit that was being changed, which is useful for some speed
3346 The following functions have been added to enhance the badblocks list
3347 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3348 ext2fs_badblocks_equal.
3350 The ext2 header files now have the latest journalling fields to the
3353 The ext2fs_mkdir function in libext2fs now properly backs out of error
3354 conditions robustly.
3356 Cleaned up makefiles:
3357 - to cleanly compile with the -j flag.
3358 - so distclean removes all generated files.
3359 - so in case of an error while installing header files, the make aborts.
3361 Fix test_script so that it works correctly when compiling in the
3364 The random UUID generation routine has been made slightly better in
3365 the case where /dev/random doesn't exist. (Use of randomly-based UUID
3366 is still not recommended if /dev/random doesn't exist, however; it's
3367 better to use the time/ethernet MAC address UUID in this case.)
3369 Clean up the build process so it's more friendly in case of missing
3372 The ext2fs header file can now be #include'd into C++ programs.
3374 The e2p.h header file is now installed.
3376 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3380 E2fsprogs 1.18 (November 10, 1999)
3381 ==================================
3383 Fix a core dumping bug in e2fsck if an imagic inode is present or
3384 (more rarely) if the filesystem is badly corrupted enough that e2fsck
3385 has to restart pass 1 processing. E2fsck now closes the filesystem
3386 before freeing a large number of its data structures, so in the case
3387 of future memory faults, at least the fixed filesystem will be fully
3390 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3391 imagic inode, it will offer to clear the imagic flag.
3393 E2fsck will now offer to clear the immutable flag on special files
3394 (device/socket/fifos) when running it in non-preen mode.
3396 E2fsck will now set the filetype when creating /lost+found, and when
3397 connected orphaned inodes to /lost+found.
3399 Debugfs's ncheck and icheck commands now handles the case where there
3400 are bad blocks in the inode table without bombing out.
3402 The badblocks list processing code has been made more efficiently for
3403 appending a large number of (ordered) badblocks to the badblocks list.
3405 Some minor man page updates.
3407 Fsck now allows interactive e2fsck's when using fsck -As (not a common
3408 mode, but some people like to do this in boot scripts for silly reasons).
3413 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3414 with the problem code convention.
3416 The badblocks list regression test program has been updated to work
3417 with previously made API name changes.
3419 The ext2fs_free() command now uses the new badblocks API to avoid
3420 using the compatibility layer.
3422 Added new regression test cases; the run_e2fsck test script now
3423 supports the ability for a test case to run a prepratory command
3424 before running e2fsck.
3426 E2fsprogs 1.17 (October 26, 1999)
3427 =================================
3429 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3432 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3433 thus potentially causing problems if a binary UUID contained a NULL
3436 E2fsck now uses stricter checks for directory entries in pass 2:
3437 zero-length filenames are not allowed; neither are 8 byte long
3440 The debugfs "dirty" command now clears the filesystem valid bit.
3441 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
3442 bit in the in-core superblock image. The new functionality is more
3443 what the user expects, and is more useful.)
3445 Added a debugging hook to test parallel fsck; if the environment
3446 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3447 will be checked in parallel when they normally would not be.
3452 Fixed some #ifdef's for compilation under the Hurd OS.
3454 Fixed minor W2K compatibility problems.
3456 Fixed some miscellaneous GCC warnings.
3459 E2fsprogs 1.16 (October 22, 1999)
3460 =================================
3462 Fixed a race condition bug in fsck; when printing a progress bar, if
3463 checking multiple filesystems in parallel, it was possible for fsck to
3464 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3465 handler, which would cause it to terminate with a signal 10.
3467 E2fsck now properly handles filesystems that have the
3468 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3469 filesystem into using or not using FILETYPE feature.
3471 E2fsck now properly handles filesystems that have the IMAGIC feature
3472 turned on (this is used on Linux AFS servers).
3474 The mke2fs program now creates filesystems that have the filetype and
3475 sparse_superblock features enabled by default, unless it is run on a
3476 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3477 so there is now a new flag -O which allows the user to specify with
3478 which features she would like to create the filesystem; "mke2fs -O
3479 none" will create a filesystsem compatible with 2.0 kernels.
3481 The tune2fs program now has a -O option which allows the user to set
3482 and reset "safe" filesystem features. Currently, the only ones which
3483 allows to be modified are the filetype and sparse_superblock features.
3484 Note setting or clearing either feature will require running e2fsck on
3485 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3486 requires that there is enough free space on the filesystem for the
3487 extra superblocks which will be created by e2fsck.)
3489 Debugfs can now set and print filesystem features in the superblock
3490 using the "features" command. Dumpe2fs will print out the complete
3491 set of features when listing the superblock.
3493 Dumpe2fs has new options -f (force) and -h (header-only).
3495 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3496 message to come up. This could happen when decrementing or
3497 incrementing a link count could result in an overflow.
3499 Fixed a bug in e2fsck where the block count on the lost+found
3500 directory would not be properly incremented when the directory was
3501 expanded to the point where an indirect block needed to be allocated.
3503 E2fsck now makes some additional sanity checks on the superblock to
3504 avoid crashing or giving a memory allocation error if some of the
3505 values in the superblock are unresonable (but the superblock otherwise
3508 Fixed a bug in e2fsck where a very badly corrupted filesystem might
3509 require two passes to completely fix the filesystem. This happened if
3510 an inode claimed blocks that was part of the filesystem metadata
3511 (typically, when garbage was written into an inode table or indirect
3512 block, since this kind of filesystem corruption normally doesn't
3515 On the Alpha, glibc declares st_flags although it isn't actually used;
3516 the configure script was improved to detect this case so that
3517 e2fsprogs can avoid using the non-functional stat field.
3519 The manual pages were updated to use a more consistent formatting
3520 style consistent with standard Unix man pages. Mke2fs's man page
3521 added documentation for a few previously undocumented options.
3523 Fixed minor display bugs in tune2fs and mke2fs.
3528 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
3530 Added features to parse and print feature strings into the e2p library.
3531 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
3533 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
3534 whose directory entries contain proper filetype information if the
3535 filesystem supports it.
3537 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
3538 the directory entry filetype information. This is used to set the
3539 directory entry filetype information if the filesystem supports it.
3541 Fixed a bug in ext2fs_expand_dir() where the block count in a
3542 directory's inode would not be properly incremented when the directory
3543 was expanded to the point where an indirect block needed to be
3547 E2fsprogs 1.15 (July 18, 1999)
3548 ==============================
3550 Add configuration checks so that e2fsprogs will compile cleanly on
3551 Linux 2.3 kernels that have renamed i_version to i_generation.
3553 E2fsck now prints a progress/completion bar (and not just a simple
3554 spinner) if the -C0 option is requested or if it receives a SIGUSR1
3555 signal. Fsck will automatically manage the (potentially muliple)
3556 e2fsck processes to print completion bars if it is given a -C option,
3557 with the right thing happening if multiple filesystems are being
3558 checked in parallel.
3560 Mke2fs now has better automatic hueristics to determine the filesystem
3561 parameters to be used for a particular filesystem. Added a new option
3562 -T which allows the user to specify how the filesystem is to be used,
3563 which helps mke2fs do a better job selecting the filesystem parameters.
3565 Mke2fs now creates revision 1 filesystems by default, and with the
3566 sparse superblock feature enabled. The sparse superblock feature is
3567 not understood by Linux 2.0 kernels, so they will only allow read-only
3568 mounts of filesystems with this sparse superblocks.
3570 Fix bug where if /dev/null couldn't be opened (should never happen),
3571 e2fsck would hang in a tight loop.
3573 Make e2fsck handle the case where /lost+found isn't a directory.
3575 E2fsck now uses mallinfo if it exists to get accurate statistics about
3578 Fix bug in e2fsck where it wouldn't check to see if a disconnected
3579 inode had any problems before connecting it to /lost+found.
3581 Add check to e2fsck so it makes sure that total number of inodes in
3582 the filesystem is a sane number.
3584 Fix fencepost error when clearing an the end of the block bitmap which
3585 caused the last block in the bitmap not to get cleared.
3587 Cleaned up a number of messages in e2fsck:
3588 * The message "Group's #'s copy of the group descriptor..."
3589 was fixed so that the correct number would be displayed.
3590 * Added missing space in the "disk write-protected" error messsage
3591 * Cleaned up the error message printed when a non-interactive
3592 e2fsck needs to abort a check because the filesystem
3593 appears to be mounted.
3595 Added a new command-line utility, uuidgen, which will create and print
3598 Make debugfs's icheck command more robust by checking to make sure an
3599 inode has valid blocks before interarting over the inode's blocks.
3601 UUID generation now uses a random-based scheme whenever possible to
3602 prevent potential privacy problems.
3604 Man pages for all of the UUID functions in the lirbary were added.
3606 Fixed bug in fsck so it won't coredump if a filesystem not in
3607 /etc/fstab is given to it.
3609 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
3610 that most of the other mount utilities understands.
3612 Mke2fs will make a filesystem even if it appears mounted if the force
3615 Dumpe2fs has new command-line options which allow a filesystem expert
3616 to specify the superblock and blocksize when opening a filesystem.
3617 This is mainly useful when examining the remains of a toasted
3620 The badblocks program has been updated to display correctly on disks
3621 with large block numbers.
3623 The badblocks program no longer gives spurious errors when errors
3624 occur on non-block boundaries, which is common if the blocksize is
3627 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
3628 MKE2FS_SYNC environment variable is set. This is to work around a VM
3629 bug in the 2.0 kernel. I've heard a report that a RAID user was able
3630 to trigger it even using a 2.2 kernel, but hopefully it will not be
3631 needed for most Linux 2.2 users.
3633 Fixed miscellaneous documentation and man pages.
3638 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
3639 in e2fsck's pass1.c really should have been static.
3641 The return value of the uuid_compare() function was changed to make it
3642 match with the convetions used by strcmp, memcmp, and Paul Leach's
3643 UUID sample document.
3645 The "make depend" process has now been made more automated; it now
3646 automatically word-wraps the dependencies, and only replaces source
3647 Makefile.in if there has been a change in the dependencies. Also, a
3648 top-level "make depend" now recurses through all the subdirectories
3651 The Makefile in .../util has been changed so that subst is built using
3652 the native C compiler during a cross-compilation, since the subst
3653 program is only used during the build process. Also add an explicit
3654 rule to build util/subst by cd'ing to the correct directory and
3657 The man directories are defined in terms mandir, so that the configure
3658 script can override the location of the manual pages.
3660 The config files have been updated to recognize new machine types for
3661 both the i386 and alpha families.
3663 Fsck has been modified so that it will accurately create an
3664 fsck_instance even when the noexecute flag is set. This allows for
3665 accurate debugging of the fsck pass structure. Also, when the verbose
3666 flag is given twice, fsck will print debugging information about when
3667 fsck is waiting for jobs to finish.
3670 E2fsprogs 1.14 (January 9, 1999)
3671 ================================
3673 Fix the fstab parsing code so that it can handle blank lines and
3674 comment characters. Also, missing pass numbers need to be treated as
3677 Fixed a bug in e2fsck where under some circumstances (when e2fsck
3678 needs to restart processing after fixing an egregious inconsistency)
3679 it would try to access already freed memory.
3681 E2fsck now prints non-printable characters in directory entries and
3682 pathnames using '^' and 'M-' notation.
3684 Fixed chattr so that it will ignore symbolic links when doing
3685 recursive descent traversals. For both chattr and lsattr, no longer
3686 print the version string unless the -V option is given.
3688 Allow the system administrator to directly specify the number of
3689 inodes desired in the filesystem, for some special cases where this is
3692 Fix portability problems so that e2fsprogs can be compiled under Linux
3693 1.2 systems and Solaris systems.
3695 Update the config.guess file with a more recent version that will
3696 identify newer Linux platforms.
3701 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
3702 an inode number of zero is passed to them.
3704 E2fsprogs 1.13 (December 15, 1998)
3705 ==================================
3707 Fixed a bug in debugfs where an error messages weren't getting printed
3708 when the ext2 library routines to read inodes returned errors in the
3709 stat, cmri and rm commands.
3711 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
3712 provided, it won't create an inode table smaller than the minimum
3713 number of inodes required for a proper ext2 filesystem.
3715 Fsck now parses the /etc/fstab file directly (instead of using
3716 getmntent()), so that it can distinguish between a missing pass number
3717 field and pass number field of zero. This caused problems for
3718 diskless workstations where all of the filesystems in /etc/fstab have
3719 an explicit pass number of zero, and fsck could not distinguish this
3720 from a /etc/fstab file with missing pass numbers.
3722 E2fsck will create a /lost+found directory if there isn't one in the
3723 filesystem, since it's safer to create the lost+found directory before
3726 Fixed e2fsck so that it would detect bogus immutable inodes which
3727 happen to be sockets and FIFO files, and offer to clear them.
3729 If a filesystem has multiple reasons why it needs to be checked, and
3730 one of the reasons is that it is uncleanly mounted, e2fsck will print
3731 that as the reason why the filesystem is being checked.
3733 Cleaned up the output routines of mke2fs so that it doesn't overflow
3734 an 80 column display when formating really big filesystems.
3736 Added a sanity check to e2fsck to make sure that file descriptors 0,
3737 1, 2 are open before opening the hard disk. This avoids a problem
3738 where a broken program might exec e2fsck with those file descriptors
3739 closed, which would cause disastrous results if the kernel returns a
3740 file descriptor for the block device which is also used by FILE *
3743 Fixed up the e2fsck progress reporting functions so that the values
3744 reliably reach 100% at the completion of all of the e2fsck passes.
3746 Fixed minor documentation bugs in man pages and usage messages.
3751 Fixed a number of lint warnings in the ext2fs library and potential
3752 portability problems from other OS's header files that might define
3753 CPP macros for names like "max" and "min".
3755 ext2fs_badblocks_list_add() has been made more efficient when it needs
3756 to grow the bad blocks list.
3758 Fixed a bug in e2fsck which caused it to dereference a freed pointer
3759 just before exiting.
3761 Fixed the substition process for generating the mk_cmds and compile_et
3762 scripts so that they will work outside of the build tree.
3764 Add sanity check to e2fsck so that if an internal routine
3765 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
3766 and causing a core dump. This should never happen, but...
3768 E2fsprogs 1.12 (July 9, 1998)
3769 ==================================
3771 E2fsprogs now works with glibc (at least with the version shipped wtih
3772 RedHat 5.0). The ext2fs_llseek() function should now work even with
3773 i386 ELF shared libraries and if llseek() is not present. We also
3774 explicitly do a configure test to see if (a) llseek is in libc, and
3775 (b) if llseek is declared in the system header files. (See standard
3776 complaints about libc developers don't understand the concept of
3777 compatibility with previous versions of libc.)
3779 The ext2fs library now writes out the block group number in each of
3780 the superblock copies. This makes it easier to automatically
3781 determine the starting block group of the filesystem when the block
3782 group information is trashed.
3784 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
3785 which means that e2fsprogs will ignore the high 8 bits of the
3786 directory entry's name_len field, so that it can be used for other
3789 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
3790 E2fsprogs will now support filesystems with 64-bit sized files.
3792 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
3794 Added new program "e2label", contributed by Andries Brouwer. E2label
3795 provides an easy-to-use interface to modify the filesystem label.
3797 Fixed bug so that lsattr -v works instead of producing a core dump.
3799 Fixed a minor bug in mke2fs so that all groups with bad superblock
3800 backup blocks are printed (not just the first one).
3802 Mke2fs will check the size of the device, and if the user specifies a
3803 filesystem size larger than the apparent size of the device it will
3804 print a warning message and ask if the user wants to proceed.
3806 E2fsck has a new option -C, which sends completion information to the
3807 specified file descriptor. For the most part, this is intended for
3808 programs to use, although -C 0 will print a spinning character to the
3809 stdout device, which may be useful for users who want to see something
3810 happening while e2fsck goes about its business.
3812 Fixed a bug in e2fsck which could cause a core dump when it needs to
3813 expand the /lost+found directory, and sometimes the bitmaps haven't
3814 been merged in. Also fixed a related bug where ext2fs_write_dir_block
3815 was used to write out a non-directory block. (Which would be bad on a
3816 non-Intel platform with byte swapping going on.)
3818 Fixed bug in e2fsck where it would print a "programming error" message
3819 instead of correctly identifying where a bad block was in used when
3820 the bad block was in a non-primary superblock or block group
3821 descriptor. Also fixed a related bug when sparse superblocks are in
3822 use and there is a bad block where a superblock or block group
3823 descriptor would have been in a group that doesn't include a
3826 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
3827 the block group descriptor table is corrupt, it was possible to try to
3828 allocate a huge array, fail, and then abort e2fsck.
3829 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
3830 and subsitutes reasonable values if the descriptors are obviously bogus.
3832 If e2fsck finds a device file which has the immutable flag set and the
3833 i_blocks beyond the normal device number are non-zero, e2fsck will
3834 offer to remove it, since it's probably caused by garbage in the inode
3837 When opening a filesystem, e2fsck specially checks for the EROFS error
3838 code, and prints a specific error message to the user which is more
3841 If the filesystem revision is too high, change the e2fsck to print
3842 that this is either because e2fsck is out of date, or because the
3843 superblock is corrupt.
3845 E2fsck now checks for directories that have duplicate '.' and '..'
3846 entries, and fixes this corruption.
3848 E2fsck no longer forces a sync of the filesystem (with attendant sleep
3849 calls) at all times. The ext2fs_flush() function now performs a sync
3850 only if it needed to write data blocks to disk.
3852 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
3853 certain errors would not be properly reported.
3855 Updated and expanded a few points in the man pages which users
3856 complained wheren't explicit enough.
3858 Added special case byte-swapping code if compiling on the PowerPC, to
3859 accomodate the strange big-endian variant of the ext2 filesystem that
3860 was previously used on the PowerPC port.
3866 Removed C++ keywords from the ext2fs libraries so that it could be
3869 E2fsck's internal organization has now been massively reorganized so
3870 that pass*.c don't have any printf statements. Instead, all problems
3871 are reported through the fix_problem() abstraction interface. E2fsck
3872 has also been revamped so that it can be called as a library from a
3875 Added new fileio primitives in libext2fs for reading and writing
3876 files on an unmounted ext2 filesystem. This interface is now used by
3879 Added a new libext2fs function for mapping logical block numbers of
3880 a file to a physical block number.
3882 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
3883 a block, zeros it, and updates the filesystem accounting records
3886 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
3887 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
3889 The libext2fs functions now use a set of memory allocation wrapper
3890 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
3891 instead of malloc, free, and resize. This makes it easier for us to
3892 be ported to strange environments where malloc, et. al. aren't
3893 necessarily available.
3895 Change the libext2fs fucntion to return ext2-specific error codes
3896 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
3897 and depending on the existence of system error codes (such as EEXIST
3900 Renamed io.h to ext2_io.h to avoid collision with other OS's header
3903 Add protection against ext2_io.h and ext2fs.h being included multiple
3906 The types used for memory lengths, etc. have been made more portable.
3907 In generla, the code has been made 16-bit safe. Added Mark
3908 Habersack's contributed DOS disk i/o routines.
3910 Miscellaneous portability fixes, including not depending on char's
3913 The io_channel structure has a new element, app_data, which is
3914 initialized by the ext2fs routines to contain a copy of the filesystem
3917 ext2fs_check_directory()'s callback function may now return the error
3918 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
3919 really do the checking, despite the presence of the callback function.
3922 E2fsprosg 1.11 (June 17, 1997)
3923 ==============================
3925 Fixed e2fsck to detect (previously ignored) conflicts between the
3926 superblock or block group descriptors and block bitmaps, inode
3927 bitmaps, and inode tables.
3929 Fixed bug in e2fsck so that when the message printed out when a block
3930 or inode bitmap conflicts with other data, it has the correct group
3933 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
3934 to badblocks. This meant that not all of the filesystem was being
3935 tested for bad blocks!
3937 Fixed an array boundary overrun case which cropped up in
3938 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
3941 Adjusted the number of columns printed by mke2fs when displaying the
3942 superblock backups to avoid running over 80 columns when making a
3943 really big filesystem.
3945 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
3946 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
3947 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
3952 Fixed install rule in lib/ss so that ss_err.h is actually getting
3955 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
3956 bassed back to the caller.
3958 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
3959 setting the current inode number (which meant this function wasn't
3962 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
3963 blocks in the bitmap when increasing the size of the bitmap.
3965 Changed the initial number of blocks allocated by ext2fs_init_dblist()
3966 to be more realistic.
3968 Added a new function ext2fs_allocate_group_table, which sets up the
3969 group descriptor information (and allocates inode and block bitmaps,
3970 and inode tables for a particular group). The function was created by
3971 factoring out code form ext2fs_allocate_tables().
3973 Added a new function ext2fs_move_blocks which takes a bitmap of the
3974 blocks to be moved, and moves them to another location on the
3977 Make the unix_io channel's io_channel_flush implementation calls sync()
3978 to to flush the kernel buffers to disk.
3980 Added a new function ext2fs_dblist_count returns the number of
3981 directory blocks in dblist.
3984 E2fsprogs 1.10 (April 24, 1997)
3985 ===============================
3987 Mke2fs once again defaults to creating revision #0 filesystems, since
3988 people were complaining about breaking compatibility with 1.2 kernels.
3989 Warning messages were added to the mke2fs and tune2fs man pages that
3990 the sparse superblock option isn't supported by most kernels yet (1.2
3991 and 2.0 both don't support parse superblocks.)
3993 Added new flag to mke2fs, -R <raid options>, which allows the user to
3994 tell mke2fs about the RAID configuration of the filesystem. Currently
3995 the only supported raid option is "stride" which specifies the width
3998 Fixed bug in e2fsck where pass1b would bomb out if there were any
3999 blocks marked bad in the inode table.
4001 Fixed rare bug in mke2fs where if the user had a very unlucky number
4002 of blocks in a filesystem (probability less than .002) the resulting
4003 filesystem would be corrupt in the last block group.
4005 Fixed bug where if e2fsck tried to allocate a block to fix a
4006 filesystem corruption problem and the filesystem had no free blocks,
4007 ext2fs_new_block() would loop forever.
4009 The configure script now checks explicitly to see if "-static" works,
4010 since that can't be assumed to be true --- RedHat doesn't install
4011 libc-static by default.
4013 Fixed bug in libext2's block iterator functions where under some
4014 cirmcustances, file with holes would cause the bcount parameter to the
4015 callback function to be incorrect. This bug didn't affect any of
4016 e2fsprogs programs, but it was discovered by Paul Mackerras, the
4017 author of the PPC boot loader.
4019 Removed use of static variables to store the inode cache in libext2fs.
4020 This caused problems if more than one filesystem was accessed via
4021 libext2fs (static variables in libraries are generally a bad idea).
4022 Again, this didn't affect e2fsprogs programs, but it was discovered by
4025 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
4026 will compile cleanly with 1.2.13 kernels (even with a.out shared
4032 Added new functions to duplicate an ext2 filesystem handle, and its
4033 associated substructure. New functions: ext2fs_dup_handle(),
4034 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
4035 Other structures, such as the io_channel and the inode_cache, now have
4036 a ref count so that they only get freed when they are no longer used
4037 by any filesystem handle. (These functions were added as part of the
4038 development effort for an ext2 resizer).
4040 E2fsprogs 1.09 (April 14, 1997)
4041 ===============================
4043 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
4044 accidentally introduced in the 1.08 release. The overhead calculation
4045 was accidentally removed, which caused ext2fs_initialize() to not
4046 notice when the filesystem size needed to be adjusted down because
4047 there wasn't enough space in the last block group.
4049 Fixed bug in version parsing library routine; it was always parsing
4050 the library version string, instead of using the passed-in string.
4052 Clarified chattr man page.
4054 E2fsprogs 1.08 (April 10, 1997)
4055 ===============================
4057 E2fsck 1.07 was very slow when checking very large filesystems with a
4058 lot of files that had hard links (i.e., news spools). This was fixed
4059 by seriously revamping the icount abstraction. Added a formal test
4060 suite for the icount abstraction.
4062 Debugfs now has a "-l" option to the "ls" command, which lists the
4063 inode number, permissions, owner, group, size, and name of the files
4066 Fix a bug in e2fsck where when a directory had its blocks moved to
4067 another location during the pass 1b processing, the directory block
4068 list wasn't updated, so pass 2 wouldn't check (and correct) the
4069 correct directory block.
4071 E2fsck will now treat inodes which contain blocks which are claimed by
4072 the filesystem metadata by treating them as multiply claimed blocks.
4073 This way, the data in those blocks can be copied to a new block during
4074 the pass 1b--1d processing.
4076 E2fsck will attempt to determine the correct superblock number and
4077 display it in the diagnostic and warning messages if possible.
4079 Add support for a new (incompatible) feature, "sparse_super". This
4080 feature reduces the number of blocks which contain copies of backup
4081 superblocks and block group descriptors. (It is only an incompatible
4082 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
4083 support a new -s option; e2fsck will recognize filesystems built with
4084 this feature turned on.
4086 E2fsck now checks the library to make sure is the correct version,
4087 using new library functions. (This helps to diagnose incorrectly
4088 installed e2fsprogs distributions.)
4090 Dumpe2fs now prints more information; its now prints the the
4091 filesystem revision number, the filesystem sparse_super feature (if
4092 present), the block ranges for each block group, and the offset from
4093 the beginning of the block group.
4095 Mke2fs now distributes the inode and block bitmap blok so that the
4096 won't be concentrated in one or two disks in RAID/striping setups.
4097 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
4098 choose the largest blocks per group that be chosen. (For 2k blocks,
4099 you can have up to 16384 blocks/group; for 4k blocks, you can have up
4100 to 32768 blocks/group.) Previously mke2fs would not allow
4101 specification of more than 8192 blocks per group, even if you were
4102 using a 2k or 4k block group.
4107 Added a new function ext2fs_create_icount2() which takes a "hint"
4108 argument. This hint argument presets the icount array with the list
4109 of inodes which actually need to be in the icount array. This really
4110 helps to speed up e2fsck.
4112 Added a new function ext2fs_icount_validate() which checks the rep
4113 invariant for the icount structure. This is used mostly for testing.
4115 The error mesasage given when a bad inode number is passed to
4116 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
4117 EXT2FS_UNMARK_ERROR).
4119 Added a new function ext2fs_set_dir_block which sets the block of a
4120 dblist entry, given the directory inode and blockcnt.
4122 Added a new function ext2fs_get_library_version() which returns the
4123 current library version, and ext2fs_parse_version_string() which
4124 returns a version number based on a e2fsprogs version string.
4126 The icount functions will return EINVAL if the passed in inode number
4129 E2fsprogs 1.07 (March 9, 1997)
4130 ==============================
4132 E2fsck is now uses much less memory when checking really large
4133 filesystems (or rather, filesystems with a large number of inodes).
4134 Previously a filesystem with 1 million inodes required 4 megabytes of
4135 memory to store inode count statistics; that storage requirement has
4136 now been reduced to roughly half a megabyte.
4138 E2fsck can now properly deal with bad blocks appearing inside the
4139 inode table. Instead of trying to relocate the inode table (which
4140 often failed because there wasn't enough space), the inodes in the bad
4141 block are marked as in use.
4143 E2fsck will automatically try to use the backup superblocks if the
4144 primary superblocks have a bad magic number or have missing meta-data
4145 blocks (or meta-data blocks which are out of range).
4147 E2fsck's pass 3 has been made more efficient; most noticeable on
4148 filesystems with a very large number of directories.
4150 Completely revamped e2fsck's system of printing problem reports. It
4151 is now table driven, to make them more easily customizeable and
4152 extendable. Error messages which can be printed out during preen mode
4153 are now one line long.
4155 Fixed e2fsck's filesystem swapping code so that it won't try to swap
4156 fast symbolic links or deleted files.
4158 Fixed e2fsck core dumping when fixing a filesystem which has no
4159 directories (not even a root directory).
4161 Added a check to e2fsck to make sure that the length of every
4162 directory entry is a multiple of 4 (since the kernel complains if it
4165 Added a check to e2fsck to make sure that a directory entry isn't a
4166 link to the root directory, since that isn't allowed.
4168 Added a check to e2fsk to now make sure the '.' and '..' directory
4169 entries are null terminated, since the 2.0 kernel requires it.
4171 Added check to write_bitmaps() to make sure the superblock doesn't get
4172 trashed if the inode or block bitmap is marked as being block zero.
4174 Added checking of the new feature set fields in the superblock, to
4175 avoid dealing with new filesystem features that this package wasn't
4178 Fixed a fencepost error in ext2fs_new_block() which would occasionally
4179 try to allocate a block beyond the end of a filesystem.
4181 When the UUID library picks a random IEEE 802 address (because it
4182 can't find one from a network card), it sets the multicast bit, to
4183 avoid conflicting with a legitimate IEEE 802 address.
4185 Mke2fs now sets the root directory's owner to be the real uid of the
4186 user running mke2fs. If the real uid is non-zero, it also sets
4187 the group ownership of the root directory to be the real group-id of
4188 the user running mke2fs.
4190 Mke2fs now has more intelligent error checking when it is given a
4191 non-existent device.
4193 When badblocks is given the -vv option, it now updates the block that
4194 it is currently testing on every block.
4196 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
4197 currently correctly if PATH wasn't already set.
4199 Shared libraries now built with dependencies. This allows the shared
4200 library files to be used with dlopen(); it also makes the transition
4201 to libc 6 easier, since ld.so can tell which libc a particular shared
4202 library expects to use.
4207 Added new abstraction (defined in dblist.c) for maintaining a list of
4208 blocks which belongs to directories. This is used in e2fsck and other
4209 programs which need to iterate over all directories.
4211 Added new functions which test to see if a contiguous range of blocks
4212 (or inodes) are available. (ext2fs_*_bitmap_range).
4214 Added new function (ext2_inode_has_valid_blocks) which returns true if
4215 an inode has valid blocks. (moved from e2fsck code).
4217 Added new function (ext2fs_allocate_tables) which allocates the
4218 meta-data blocks as part of initializing a filesystem. (moved from
4221 Added a new I/O manager for testing purposes. It will either allow a
4222 program to intercept I/O requests, or print debugging messages to
4223 trace the activity of a program using the I/O manager.
4225 The badblocks_list functions now store the bad blocks in a sorted
4226 order, and use a binary search to speed up badblocks_list_test.
4228 The inode scan function ext2fs_get_next_inode() may now return a soft
4229 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
4230 those cases where part of an inode table is missing or there is a bad
4231 block in the inode table.
4233 Added a new function (ext2fs_block_iterate2) which adds new arguments to
4234 the callback function to return a pointer (block and offset) to the
4235 reference of the block.
4237 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
4238 application to jump to a particular block group while doing an inode
4241 The badblocks list functions were renamed from badblocks_* to
4242 ext2fs_badblocks_*. Backwards compatibility functions are available
4243 for now, but programs should be modified to use the new interface.
4245 Some of the library functions were reorganized into separate files to
4246 reduce the size of some programs which statically link against the
4249 Put in some miscellaneous fixes for the Alpha platform.
4252 E2fsprogs 1.06 (October 7, 1996)
4253 ================================
4255 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
4256 smash the backup copies in ext2fs_close(). (The problem was that when
4257 e2fsck -p discovered the problem, while it was closing the filesystem
4258 and exiting, it was also blowing away the backup superblocks on the
4259 disk, which was less than friendly.) We now make it the case that we
4260 only write out the backup superblock and the back block descriptors if
4261 the filesystem is completely free from problems.
4263 Fixed a bug in block_interate in the lib/ext2fs library which caused
4264 e2fsck to fail on GNU Hurd-created filesystems.
4266 Add support for Linux/FT's bootloader, which actually uses
4267 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
4270 Add support for the "A" (no atime update) attribute. (Note: this
4271 attribute is not yet in production kernels.)
4273 The test suite is not automatically run when doing a "make all" from
4274 the top level directory. Users should manually run "make check" if
4275 they wish to run the test suite.
4277 Upon a preenhalt(), make the printed message more explicit that
4278 running e2fsck "MANAULLY" means without the -p or -a options.
4280 In e2fsck, if a disconnected inode is zero-length, offer to clear it
4281 instead of offering to connect it to lost+found.
4283 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
4284 e2fsck to be run over it, change e2fsck to explicitly display this
4287 For dumpe2fs and e2fsck, cause the -V option to print out which
4288 version of the ext2fs library is actually getting used. (This will
4289 help detect mismatches of using a 1.06 utility with a 1.05 library,
4295 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
4296 the naming convention.
4298 In ext2fs_initialize(), make sure the description for the inode bitmap
4299 is correctly initialize.
4301 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4303 E2fsprogs 1.05 (September 7, 1996)
4304 ==================================
4306 Add support for new fields in the ext2 superblock --- volume name,
4307 volume UUID, and last mounted field. Dumpe2fs displays these fields,
4308 tune2fs and mke2fs allows you to set them. E2fsck will automatically
4309 generate a UUID for those volumes that don't have them.
4311 Put in support for e2fsck to recognize HURD specific ext2 features ---
4312 most notably, the translator block. The e2fsprogs tools will now use
4313 the creator_os field in the superblock to correctly handle different
4314 OS-specific variants of the ext2 filesystem.
4316 E2fsck now fixes inodes which have a the deletion time set, but which
4317 have a non-zero i_link_count field by offering to clear the deletion
4318 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4319 ext2 kernel behavior) and offered to unlink the file.
4321 If e2fsck sets the clean bit, but nothing else, set the exit code
4322 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4323 set the filesystem valid bit when it was previously cleared. :-) This
4324 was needed to make the HURD fsck driver happy.
4326 If the user refuses to attach an unattached inode, e2fsck will no
4327 longer set the inode's link count. Otherwise, the inode would end up
4328 getting marked as unused, which might cause loss of data later.
4330 Make the message issued by e2fsck when the superblock is corrupt less
4331 confusing for users. It now mentions that another reason for the
4332 "corrupt superblock" message might be that the partition might not be
4333 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4335 Make the libext2 library more robuest so that e2fsck won't coredump on
4336 an illegal superblock where the blocksize is zero. (f_crashdisk is
4339 By default, create filesystems where the default checkinterval is 6
4340 months (180 days). Linux servers can be robust enough that 20 reboots
4341 can be a long, long time.
4343 Added configure flag --enable-old-bitops, which forces the bitops to
4344 use the old (native) bitmask operations. By default on the sparc
4345 platform, the standard ext2 bit ordering is now used.
4347 Added a new feature to e2fsck to byte-swap filesystems; this can be
4348 used to convert old m68k filesystems to use the standard byte-order
4349 storage for the superblock, inodes, and directory blocks. This
4350 function is invoked by using the '-s' option to e2fsck.
4352 Debugfs's "dump" command has been enhanced so that it writes out the
4353 exact size of the file so that the nulls at the end of the file are
4354 eliminated. The command also accept a new "-p" option which will
4355 attempt preserve to preserve the ownernship, permissions, and
4356 file modification/access times.
4358 Debugfs has two new options, -f and -R. The -R option allows the user
4359 to execute a single debugfs command from the command line. The -f
4360 option allows the user to specify a "command file" containing debugfs
4361 commands which will get executed.
4363 Dumpe2fs now pretty prints the check interval, instead of just
4364 printing the check interval as a number of seconds.
4366 Fix bugs in debugfs: the params command when no filesystem is opened
4367 no longer causes a core dump. It is now possible to unlink a file
4368 when a pathame containing a '/' is specified.
4370 Tune2fs has a new -C option which sets the number of times the
4371 filesystem has been mounted.
4373 Fix the chattr '-v' option so that it actually works. Chattr was
4374 being buggy about the -v option parsing.
4379 The directory lib/uuid contains a set of library routines to generate
4380 DCE compatible UUIDs.
4382 Extended ext2fs_namei() to handle symbolic links. Added new function
4383 ext2fs_nami_follow() which will follow last symbolic link in the case
4384 where the pathname points to a sym link.
4386 The ext2fs_block_iterate function will now return the HURD translator
4387 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4388 iterator to return data blocks only. The ext2fs.h file now defines
4389 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4390 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4391 count field of the iterator callback function.
4393 The test script driver now takes an optional second argument, which is
4394 the test case to be run. This allows you to run a test case without
4395 needing to run the entire test suite.
4397 On Linux ELF systems, install the .so files in the correct places
4398 (/usr/lib). The .so files must be stored in the same directory as the
4401 Fixed miscellaneous HURD compilation issues with header file being
4402 included in the right order.
4404 Fixed debugfs so that it resets optind to zero, not one, since setting
4405 optind to zero is more correct.
4408 E2fsprogs 1.04 (May 16, 1996)
4409 =============================
4411 First "official" (1.03 was a limited release only) to support building
4412 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4415 This package includes a RPM specs file, that it can be built using the
4416 RedHat Package Manager.
4418 E2fsck now prints a hint that if there are lots of incorrectly located
4419 inode bitmaps, block bitmaps, and inode table blocks, the user might
4420 want to try using e2fsck -b 8193 first, to see if that fares any
4423 For ext2 filesystem written with the hurd, debugfs will now print out
4424 the translator field when printing an inode structure.
4426 Lots of miscellaneous linking/installation cleanups:
4428 Libraries are now linked using a relative pathname, instead of
4429 relying on -L working correct. It doesn't, in many cases, including
4430 current versions of GNU ld. This guarantees that the build tree is
4431 linking with the right libraries, instead of the ones installed in
4434 Header files, man pages, and the et/ss shell scripts are now
4435 generated using a custom substitution script, instead of relying on
4436 the configure script. This prevents needless recompilation of
4437 files; in addition, the custom substitution script is much faster.
4439 e2fsck may now be linked dynamically, by using the
4440 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4441 since it increases e2fsck's dependence on other files, but some
4442 people need to save disk space, and other critical programs on their
4443 systems were being linked dynamically anyway.
4445 Programs such as fsck which didn't need to be linked against
4446 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4447 only link against libraries they actually need. Otherwise, those
4448 programs would require the presense of libraries that otherwise
4449 could be removed from a rescuse diskette.
4451 The ss include files are now installed correctly so they can
4452 actually be used by another package.
4454 If the profiling libraries are built, they are now installed on a
4455 "make install-libs".
4458 E2fsprogs 1.03 (March 27, 1996)
4459 ===============================
4461 Change the m68k bit numbering for bitmasks to match the bit numbering
4462 used by all other ext2 implementations. (This change was requested by
4463 the m68k kernel development team.)
4465 Support (in-development) filesystem format revision which supports
4466 (among other things) dynamically sized inodes.
4468 Fixed a bug in the ext2 library so that an intelligent error is
4469 returned if mke2fs is run with a ridiculously small number of blocks
4472 Fixed a bug in the ext2 library which required that the device be
4473 openable in read/write mode in order to determine its size. This
4474 caused e2fsck -n to require read/write access when it was not
4475 previously necessary.
4477 Fixed a bug in e2fsck which casued it to occasionally fail the test
4478 suite depending on which version of the floating point library it was
4481 Fixed a bug in e2fsck so that it now halts with a fatal error when
4482 certain superblock consistency checks fail. Previously it continued
4483 running e2fsck, with some potential confusing/damaging consequences.
4485 Added new flag to fsck which allows the root to be checked in parallel
4486 with other filesytems. This is not the safest thing in the world to
4487 do, but some system administrators really wanted it.
4489 Fixed -Wall flames in lib/ss.
4492 E2fsprogs 1.02 (January 16, 1996)
4493 =================================
4495 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4497 Change e2fsck to print statistics of how many non-contiguous files are
4498 on the system. Note that a file which is larger than 8k blocks, it is
4499 guaranteed to be non-contiguous.
4501 In mke2fs, print a warning message if a user tries to format a whole
4502 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
4503 whole disk, the -F (force) option forces mke2fs to format a whole disk
4506 Fix a bug in fsck where in some cases it might start checking
4507 partitions in the next pass before it finishes checking partitions in
4508 the current pass. This still won't cause two partitions on the same
4509 disk will be checked, so it's rarely a problem in real life.
4511 Patch lsattr so that it won't hang when checking a named pipe.
4513 Minor compilation fixes:
4514 * Fix the order of libraries that were linked in debugfs.
4515 * Allow the sources to be compiled with -ansi turned on.
