2================================
3
4When deciding whether or not to revalidate a blkid cache entry, if the
5device's mtime is newer than the last time the cached entry was
6validated, force a revalidation.
7
8Fix a potential data corruption bug in e2fsck in the journal replay.
9The chances of this is happening is extremely remote, especially the
10default data=ordered or data=writeback modes. However, if a block
11which has been journalled starts with the first four bytes 0xc03b3998,
12when e2fsck replays the journal, those four bytes will be replaced
13with zero's. Fortunately, it is highly, highly unlikely for e2fsck
14metadata to begin with those fatal 4 byte sequence, and unless
15data=ordered mode is in use, data blocks are never journaled.
16
17Updated German, Dutch, Sweedish, and Vietnamese translations.

21
22Fixed various Debian packaging issues --- see debian/changelog for
23details.

25Remove default sizes of types when cross compiling, since autoconf
262.50 can figure this out automatically now.

30=================================
Theodore Ts'o5e107622008-03-14 14:29:51 -040031
32SuSE's security team audited uuidd and came up with a few minor
33issues. None of them are serious given that uuidd runs setuid as a
34unprivileged user which has no special access other than libuuid
35directory, but it's good to get them fixed.
36
37One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
38work correctly with in-inode extended attributes.
39
Theodore Ts'o7affded2008-04-27 00:53:27 -040040Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
41translations.
42
43Debugfs will avoid using a pager if the standard output is not a tty.
44
45Fix debugfs and tune2fs to correctly handle daylight savings time when
46parsing a time string.
47
48Fixed spelling mistakes, typos, and otherwise clarified man pages.
49
50Fix fsck completion bars when multiple filesystems were being checked
51in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
52#203323, Addresses Sourceforge Bug: #1926023)
53
54Fix fsck so that progress information is sent back correctly when
55multiple filesystems are being check and the output of fsck is being
56redirected to a file descriptor. Also, include the device name (w/o
57spaces) in the progress information sent back via a file descriptor.
58(Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
59#1926023)
60
61Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
62
63If logsave receives a SIGTERM or SIGINT signal, it will now pass that
64signal to its child process.
65
66Fix mke2fs's creation of are resize inode when there is a non-standard
67s_first_data_block setting.
68
69Fix bug in blkid when run by an unprivileged user; most devices were
70not reported correctly. 9Addresses Launchpad Bug: #220275)
71
72Mke2fs will not allow the logically incorect combination of
73resize_inode and meta_bg, which had previously caused mke2fs to create
74a corrupt fileystem.
75
76Fix fsck in German locales so that a 'j' means yes.

89
90Remove bashism for configure script and from the lib/ss Makefile.
91Addresses Sourceforge Bug: 1921969
92
93Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.

100=================================
101
102Fixed e2image -I so it works on image files which are larger than 2GB.
103
104Fixed e2fsck's handling of directory inodes with a corrupt size field. If
105the size is larger than the number of blocks found in the inode, don't
106try to allocate extra empty blocks at the end of the directory to make
107up the difference; there's no point to doing that. In addition, if
108the size is not a multiple of a blocksize, always fix it.
109
110E2fsck handled a pass 2 "should never happen error" by not giving
111enough information and then core dumping. Unfortunately, it was all
112too easy to trigger the "should never happen" situation if a
113directory's inode size was not correct. This has been fixed, but
114e2fsck has also been taught how to handle this situation more
115gracefully, by simply removing the inode hash tree information, so
116that it can be rebuilt again after e2fsck's pass 3. (Addresses
117Launchpad Bug: #129395)
118
119Resize2fs had a bug resizing large inodes with extended attributes
120that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
121completely on big-endian systems such as PowerPC. The bug should be
122completely fixed now. Yay for regression test suites. (Addresses Red
123Hat Bugzilla: #434893)
124
125Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
126translations. Many thanks to Philipp Thomas from Novell for stepping
127up to become the new German translation maintainer! (Addresses Debian
128Bugs: #302512, #370247, #401092, #412882).
129
130When e2fsck is clearing a corrupt inode's HTREE directory information,
131make it clear that it is just clearing the HTREE information, not the
132entire inode.
133
134Fixed spelling mistakes, typos, and otherwise clarified man pages.
135
136Programmer's notes
137------------------
138
139Add new functions, ext2fs_dblist_get_last() and
140ext2fs_dblist_drop_last(), which allows the caller to examine the last
141directory block entry added to the list, and to drop if it necessary.
142
143Fixed a portability problem in libblkid with DJGPP.
144
145Fix an obvious typo in an "internal error" message in e2fsck. Thanks
146to Philipp Thomas for pointing this out.
147
148If the info files are not built, change "make install" so it doesn't
149fail with an error code.

Theodore Ts'oe1e83b62008-02-28 22:51:49 -0500152E2fsprogs 1.40.7 (February 28, 2008)
153====================================
154
155Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
156depreciate the -s option, since it can result in filesystems which
157e2fsck can't fix easily. There are very good reasons for wanting to
158disable sparse_super; users who wants to turn off sparse_super can use
159debugfs. (Addresses Sourceforge Bug: #1840286)
160
161Add missing options to mke2fs's usage message. (Addresses Sourceforge
162Bug: #1751393)
163
164Fix bug in resize2fs when large (greater than 128 byte) inodes are
165moved when a filesystem is shrunk; it was only moving the first 128
166bytes, so extended attributes were not getting moved. (Addresses Red
167Hat Bugzilla: #434893)
168
169E2fsck now prints an explicit message when the bad block inode is
170updated, to avoid confusion about why the filesystem was modified.
171(Addresses Sourceforge Bug: #756460)
172
173Allow mke2fs and tune2fs manipulate the large_file feature.
174Previously we just let the kernel and e2fsck do this automatically,
175but e2fsck will no longer automatically clear the large_file feature.
176It still isn't really necessary to worry about this feature flag
177explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
178#258381)
179
180Suppress message about an old-style fstab if the fstab file is empty.
181(Addresses Debian Bug: #468176)
182
183Fix (really minor) bug in debugfs's find_free_block so it avoids
184reporting a free block more than once if there are too few free blocks
185in the filesystem. (Addresses Sourceforge Bug: #1096315)
186
187Change e2fsck to no longer clear the LARGE_FILES feature flag
188automatically, when there are no more > 2GB files in the filesystem.
189It's been almost a decade since there have been kernels that don't
190support this flag, and e2fsck clears it quietly without telling the
191user why the filesystem has been changed.
192
193Fix bug which could cause libblkid to seg fault if a device mapper
194volume disappears while it is being probed. (Addresses RedHat
195Bugzilla: #433857)
196
197Inhance e2fsck's reporting of unsupported filesystem feature flags.
198(Addresses Sourceforge Feature Request: #1175808)
199
200Fix option syntax in dumpe2fs for explicit superblock and blocksize
201parameters. What was currently documented in the man page has been
202broken for some time, due to getopt() implementation changes. The
203option sytax has been changed to one which is can be more portable
204supported and which is consistent with the format for extended options
205in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
206
207Add support to tune2fs to clear the resize_inode feature. This
208requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
209
210Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
211Bugzilla: #409321)
212
213Add support for setting RAID stride and stripe-width via mke2fs and
214tune2fs. Teach dumpe2fs to print the RAID parameters.
215
216Add support for setting new superblock fields to debugfs's
217set_super_value.
218
219Add support for printing "mostly-printable" extended attributes in
220Debugfs.
221
222Add support for the -M option to fsck, which causes it to ignore
223mounted filesystem.
224
225Fix uuidd so that it creates the pid file with the correct pid number.
226(Addresses Sourceforge Bug: #1893244)
227
228Fix various gcc -Wall warnings.
229
230Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
231
232Fixed spelling mistakes, typos, and otherwise clarified man pages.

237-------------------
238
239Fixed various Debian packaging issues --- see debian/changelog for
240details. (Addresses Debian Bug: #466929)
241
242Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
243partially filled-in filesystem object on an error, so that e2fsck can
244print more intelligent error messages.
245
246Add a new function e2p_edit_feature2() which allows the caller to
247specify which feature flags are OK to set or clear, and which returns
248more specific information about feature flags which are not allowed to
249be set/cleared.
250
251Set the C locale in the test_script driver since it uses [A-Za-z].
252(Addresses Sourceforge Bug: #1890526)
253
254Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
255support lockf().
256
257Change configure.in to avoid using the 'dc' command unless it is
258absolutely needed. (i.e., when using parsing a WIP-style version
259number) (Addresses Sourceforge Bug: #1893024)
260
261Add portability checks to support compilation under DJGPP.
262
263Update to the latest samba tdb code before the LGPLv3 change, which
264fixes a realloc() leak on failure.
265
266Fix memory leak in ext2fs_alloc_block().
267
268Fix makefile dependency issues for various install targets.
269(Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)

275===================================
276
277Add support for returning labels for UDF filesystems in the blkid
278library.
279
280Fix bug in the blkid library where cached filesystems was not being
281flushed when opening USB devices returned the error ENOMEDIUM.
282(Addresses Debian Bug: #463787)
283
284Added logic to the blkid library to automatically choose whether a
285filesystem should be mounted as ext4 or ext4dev, as appropriate.
286
287Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
288
289Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
290configured with --enable-jbd-debug.
291
292Document the BLKID_FILE environment variable in the libblkid man page

301
302Don't try to create $DESTDIR/etc/init.d as part of make install as we
303don't install the init.d script (and it's not the recommended way to
304start uuidd anyway). (Addresses Sourceforge Bug: #1885085)

Theodore Ts'oc8a57082008-01-27 20:01:25 -0500311E2fsprogs 1.40.5 (January 27, 2008)
312===================================
313
314Fix a potential overflow big in e2image if the device name is too
315long.
316
317Mke2fs will now create new filesystems with 256 byte inodes and the
318ext_attr feature flag by default. This allows for much better future
319compatibity with ext4 and speeds up extended attributes even on ext3
320filesystems.
321
322Teach e2fsck to ignore certain "safe" filesystem features which are
323set automatically by the kernel. Having the kernel set features
324automagically behind the user's back is a bad idea, and we should try
325to break the kernel of this habit, especially for the newer ext4
326feature flags. But for now, we will try to avoid needless full checks
327which can annoy users who are doing fresh installs.
328
329Add support in tune2fs and mke2fs for making a filesystem as being "ok
330to be used with test kernel code". This will be needed for using test
331filesystems with the latest ext4 kernel code.
332
333Change e2fsck -fD so that it sorts non-htree directories by inode
334numbers instead of by name, since that optimizes performances much
335more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
336
337If e2image fills the disk, fix it so it exits right away instead of
338spewing large numbers of error messages.
339(Addresses-Sourceforge-Feature-Request: #606508)
340
341If ftruncate64() is not available for resize2fs, let it use ftrucate()
342instead, but have it check to see if the size would get truncated, and
343skip calling ftruncate in that case.
344
345Add support for detecting HFS+ filesystems in the blkid library.
346
347Add supprt in the blkid library for ext4/ext4dev filesystems.
348
349Fix a bug in blkid where it could die on a floating point exception
350when presented with a corrupt reiserfs image.
351
352Fix blkid's handling of ntfs UUID's so that leading zeros are printed
353such that UUID string is a fixed length.
354
355Add sample python bindings for the uuid library to the contrib
356directory. (Addresses-Sourceforge-Patches: #778817)
357
358Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
359will work with large files. (Addresses Sourceforge Feature Request:
360#1257500 and Sourceforge Support Request: #1253511)
361
362Allow the debugfs 'undel' command to undelete an inode without linking
363it to a specific destination directory, since this might require
364allocating blocks that could overwrite some yet-to-be-recovered
365deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
366
367Update Swedish translations from the Translation Project.
368
369Programmer's Notes:
370-------------------
371
372Fix configure handling of --sbindir (which should rarely be used, but
373someone did complain, so let's fix it). (Addresses Sourceforge Bug:
374#498381)
375
376Updated e2fsprogs.spec file to include a new uuidd package
377
378Use pkg-config to determine where to find the devmapper library so we
379can find out where it is located on different distributions.
380
381Fix Makefile race so that "make -j3 distclean" works correctly
382
383Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
384especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,

389Fixed various Debian packaging issues --- see debian/changelog for
390details. (Addresses Debian Bugs: #459403, #459475, #459614)
391
392Remove the --enable-dynamic-static configure option, and build e2fsck
393dynamically by default. If the user wants e2fsck.static, he/she will
394need to build it via "make -C e2fsck e2fsck.static"

401====================================
402
403Improve time-based UUID generation. A new daemon uuidd, is started
404automatically by libuuid if necessary. This daemon is setuid to allow
405updates to /var/lib/libuuid, so the clock sequence number can be
406stored and so if the clock is set backwards, it can be detected.
407(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
408#233471)
409
410Filter out the NEEDS_RECOVERY feature flag when writing out the backup
411superblocks. This avoids e2fsck from concluding that a full
412filesystem check is required before backing up the superblock due to
413changes in the feature flags. (Addresses Debian Bug: #454926)
414
415Fix fsck to only treat the '#' character as a comment at the beginning
416of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
417will cause fsck to issue an bogus warning message.
418(Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
419
420Format control characters and characters with the high eighth bit set
421when printing the contents of the blkid cache, to prevent filesystems
422with garbage labels from sending escape sequences to the user's screen
423that might, for example place it in graphics mode. (Addresses Ubuntu
424Bug: #78087)
425
426Fix sign-extension problem on 64-bit systems in in the com_err
427library. (Addresses Sourceforge Bug: #1809658)

456===================================
457
458Fix a potential security vulnerability where an untrusted filesystem
459can be corrupted in such a way that a program using libext2fs will
460allocate a buffer which is far too small. This can lead to either a
461crash or potentially a heap-based buffer overflow crash. No known
462exploits exist, but main concern is where an untrusted user who
463possesses privileged access in a guest Xen environment could corrupt a
464filesystem which is then accessed by the pygrub program, running as
465root in the dom0 host environment, thus allowing the untrusted user to
466gain privileged access in the host OS. Thanks to the McAfee AVERT
467Research group for reporting this issue. (Addresses CVE-2007-5497.)
468
469Fix hueristics in blkid which could cause a disk without partitions to
470be incorrectly skipped when a loopback device is present. (Addresses
471Red Hat Bugzilla #400321.)
472
473Fix e2image so that in raw mode it does not create an image file which
474is one byte too large.
475
476Change mke2fs's usage message so it recommends the preferred -E option
477instead of the deprecated -R option.
478
479Enhance the blkid library so it will recognize squashfs filesystems.
480(Addresses Red Hat Bugzilla #305151.)
481
482Enhance e2fsck so it will force the backup superblocks to be backed up
483if the filesystem is consistent and key constants have been changed
484(i.e., by an on-line resize) or by e2fsck in the course of its
485operations.
486
487Enhance blkid's detection of FAT filesystems; so that USB disks with
488only a single bootable partition will not get missed.
489
490E2fsck will no longer mark a filesystem as invalid if it has time
491errors (i.e., if superblock mount time or last write time is in the
492future) and the user refuses to fix the problem.

494The Ubuntu init scripts don't properly set the system time correctly
495from hardware clock if the hardware clock is configured to tick local
496time instead of GMT time. Work around this as best as we can by
497providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
498be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
499Bug #131201.)
500
501Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
502Hat Bugzilla #151533.)
503
504Fix e2fsck so that if the superblock is corrupt, but still looks
505vaguely like an ext2/3/4 superblock, that it automatically tries to
506fall back to the backup superblock, instead of failing with a hard
507error.
508
509Make the e2fsprogs program more robust so that they will not crash
510when opening a corrupt filesystem where s_inode_size is zero.
511
512Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
513arguments are detected as such and the parse error is reported to the
514user. (Addresses Debian Bug #435381.)
515
516Change e2fsck so it will not complain if a file has blocks reallocated
517up to the next multiple of a system's page size.
518
519Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
520about (valid) filesystems where the inode table extends to the last
521block of the block group. (Addresses Red Hat Bugzilla #214765.)
522
523Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
524allocating inode tables for some relatively rare odd disk sizes.
525(Addresses Red Hat Bugzilla #241767.)
526
527Add Catalan translation and update Dutch and Swedish translations
528from the Translation Project.
529
530Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
531still had an issue when trying to figure out whether we need to
532byte-swap fast symlinks that contained extended attributes.

538Programmer's Notes:
539-------------------
540
541Fix mke2fs tests to avoid needing any significant ^M (CR) characters
542
543Add "make check" to the RPM spec file
544
545Fix "make install" and 'make unstall" in misc/Makefile.in so that it
546works correctly when the prefix is not the root directory.
547
548Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
549clena up after themselves by deleting the test.img temporary file
550after completing the test.
551
552Fixed a corner case bug ext2fs_unlink() when trying to delete the
553first directory entry in a directory block and the last directory
554entry in the previous directory block is not in use. Fortunately
555ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
556places where it is extremely unlikely to run into this corner case.
557
558Fix missing dependency which would cuase parallel builds to fail.
559(Addresses Sourceforge Bug #1842331.)
560
561Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
562calling open(O_CREATE) with a missing mode parameter.
563
564Fix the test_ss.c in lib/ss so it can be used as an example
565application program for the library as well as a regression test
566suite.
567
568Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
569are properly passed back up through the call stack.

572================================
573
574A recent change to e2fsck_add_dir_info() to use tdb files to check
575filesystems with a very large number of filesystems had a typo which
576caused us to resize the wrong data structure. This would cause a
577array overrun leading to malloc pointer corruptions and segfaults.
578Since we normally can very accurately predict how big the the dirinfo
579array needs to be, this bug only got triggered on very badly corrupted
580filesystems.
581
582Fix a bug in e2fsck which caused it to incorrectly salvange
583directories when the last entry's rec_len is bogusly too big. This
584resulted in a nonsense filesystem corruption to be reported, and
585required a second run of e2fsck to fully fix up the directory.
586
587Update tune2fs man page to include more discussion of reserved blocks

595===============================
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400596
597Fix bug which could cause libblkid to loop forever. When revalidating
598a partition where there is obsolete information in /etc/blkid.tab, we
599end up freeing a the type tag without clearing dev->bid_type, causing
600blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
601
602The Turkish translation has a bug in it where it has the translation
603of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
604@E, recursively, forever, until the stack fills up and e2fsck core
605dumps. We fix this by making e2fsck stop @-expansions after a
606recursive depth of 10, which is far more than we need.
Theodore Ts'od2dc78a2007-07-14 09:03:17 -0400607(Addresses Sourceforge Bug: #1646081)
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400608
609Compile the default mke2fs.conf into mke2fs program. People are
610getting surprised by mke2fs creating filesystems with different
611defaults than earlier versions of mke2fs if mke2fs.conf is not
612present. So we now create a built in version of mke2fs.conf file
613which is used by mke2fs if the /etc/mke2fs.conf is not present.
614(Addresses SourceforgeBug: #1745818)
615
616Improve the config/parse_types.sh helper script. Fix a potential
617security problem if e2fsprogs is built as root (as Gentoo does!). In
618addition fix the script and how it is called from the configure script
619so that it does the right thing when cross-compiling. (Fixes Gentoo
620bug: #146903)
621
622Update Vietnamese, French, and Dutch PO files from the Translation
623Project. Also created a new e2fsprogs.pot file for translator.
624
625Fix bogus strip permission errors when building under Debian. When
626building the e2fsprogs dpkg's, the dh_strip command emits a large
627number of error messages caused by the permissions not being right.
628So run dh_fixperms before running dh_strip.

630Programmer's Notes:
631-------------------
632
633Add new function: profile_set_default(). This function sets the value
634of the pseudo file "<default>". If the file "<default>" had
635previously been passed to profile_init(), then def_string parameter
636will be parsed and used as the profile information for the "<default>"
637file.
638
639Fix mk_cmds's error reporting so that it is unambiguous that it is the
640mk_cmds script which is generating the error. (Obviates Gentoo patch:
641e2fsprogs-1.32-mk_cmds-cosmetic.patch)
642
643Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
644priority" environment variable that overrides all others, where as
645LANG is the lowest priorty environment variable. If LC_ALL is set, it
646doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
647the all the rest are set. This will assure that the locale when
648running the test suites is the "C" locale. (Obviates Gentoo patch:

655Fix divide by zero error in blkid's NTFS probing logic.
Theodore Ts'od7b64722007-06-24 17:32:47 -0400656
657Add new blkid -g option which causes the blkid cache to be garbage
658collected.
659
660Fix a bug in libblkid which could cause the internal field bid_type to
661become corrupted. Fortunately bid_type isn't used much, and bid_label
662and bid_uuid is only used by debugging code, so the impact of this bug
663was very minor.
664
665Mke2fs will now store the RAID stride value when a filesystem is
666created with a requested RAID stride, and then use it automatically in
667resize2fs.
668
669Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
670isn't too big. In some cases Lustre users have tried specifying an
671inode size of 4096 bytes, while keeping an inode ratio of one inode
672per 4096 bytes.
673
674Improve sanity check in e2fsck's algorithm for finding a backup
675superblock, so that it won't accidentally find a superblock that was
676located in the journal, and then later reject it as being not a valid
677backup superblock.
678
679Fix e2fsck get_size logic so that it will work with the Linux floppy
680driver. The Linux floppy driver is a bit different from the other
681block device drivers, in that if the device has been opened with
682O_EXCL, it disallows another open(), even if the second open() does
683not have the O_EXCL flag. (Addresses Debian Bug: #410569)
684
685Fix error checking of badblock's last-block and start-block arguments.
686(Addresses Debian Bug: #416477)
687
688Fix e2fsck so that it doesn't overwrite the backup superblocks when
689recovering a journal until the master superblock has been confirmed as
690being sane.
691
692Change the blkid library to be much more paranoid about concluding
693that a partition contains an NTFS filesystem, and fetch the UUID and
694LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
695#110138)
696
697Factor out the code which sets the default journal size and move it
698into libext2fs.
699
700Enhance e2fsck so it will recreate the ext3 journal if the original
701journal inode was cleared to due it being corrupt after finishing the
702filesystem check.
703
704Fix e2fsck so that it updates the journal inode if it is corrupted and
705the backup journal information from the superblock was successfully
706used to recover the filesystem.
707
708Fix e2fsck so that it checks all of the blocks in the journal inode
709for validity. The original code only checked the direct blocks to
710make sure the journal inode was sane. Unfortunately, if some or all
711of the indirect or doubly indirect blocks were corrupted, this would
712not be caught.
713
714Add support in blkid to detect LUKS encrypted partitions.
715
716Add extra sanity checks for extended attributes in the case where the
717size is zero but the offset is very large.
718
719Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
720and ext2fs_get_next_inode_full().
721
722Clarify the copyright licenses used by the various libraries in
723the top-level COPYING file (Red Hat Bugzilla: 166058)
724
725Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
726
727Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
728
729Remove check in e2fsck which requires EA's in inodes to be sorted;
730they don't need to be sorted, and e2fsck was previously wrongly
731clearing unsorted EA's stored in the inode structure.
732
733Allow mke2fs or tune2fs to create a substantially larger journal (up
734to 10,240,000 blocks).
735
736Fix MD superblock detection, and make sure the correct UUID is
737reported from the MD superblock.
738
739Fix a signed vs. unsigned bug in debugfs.
740
741Enhance debugfs's date parser so that it accepts integer values.
742
743Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
744file with multiply claimed blocks is hard linked. or not at all if the
745root directory contains shared blocks
746
747Enhance debugfs so it can modify the block group descriptors using the
748command set_block_group_descriptor.
749
750Improve e2fsck's reporting of I/O errors so it's clearer what it was
751trying to do when an error happens
752
753Fix a bug in in how e2fsprogs byte swaps inodes containing fast
754symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
755#232663 and LTC Bugzilla: #27634)

771Fix e2fsck to clear i_size for special devices with a bogus i_blocks
772field on the first pass.
773
774Fix e2fsck to set the file type of the '..' entry when connecting
775a directory to lost+found. (Addresses Lustre Bug: #11645)
776
777Enhance e2fsck to recover directories whose modes field were corrupted
778to look like special files. This is probably only useful in
779artificial test cases, but it will be useful if we ever do the "inodes
780in directory" idea for ext4.
781
782Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
783#412614)
784
785Fix resize2fs parsing of size parameter (in sector units). This was
786actually a bug in libe2p's parse_num_blocks() function. When handling
787the 's' suffix, it was ignoring the blocksize information passed in
788from the caller and always interpreting the number in terms of a 1k
789blocksize. (Addresses Debian Bug: #408298)
790
791There was a floating point precision error which could cause e2fsck to
792loop forever on really big filesystems with a large inode count.

794
795Fix memory leak in ext2fs_write_new_inode()

825Fix resize2fs so that it gives user-intelligible error messages if the
826filesystem or the kernel does not support on-line resizing.
827(Addresses Debian Bug: #380548)
828
829Require mke2fs -F -F for really dangerous operations, since -F is
830needed for less dangerous operations such as creating filesystems
831images in regular files, or creating filesystems on whole block
832devices. These relatively innocuous usages should NOT be confused
833with running mke2fs on an apparently-mounted or in-use filesystem.
834

917filesystems contained in regular files where the filesystem image size
918is returned by stat64().
919

946Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
947
948Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
949
950If diff -u is supported, use it to report test failures.
951
952Updates/improvements to RPM spec file
953
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500954Add on-disk format definitions for the following new features:
955EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
956EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
957EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
958
959Add a new make target "checked-failed" in the tests directory which
960reruns any failed tests
961
962Update draft-leach-uuids-guids-01.txt with rfc4122.txt
963
Theodore Ts'oa0d42542007-04-07 11:05:10 -0400964Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
965pointer dereferences, memory leaks, etc. None were security-criticial
966problems.
967
968Fix up usage and decrement error messages in the test_icount program
969
970Add debugging code to the com_err library; if the environment variable
971COMERR_DEBUG is set to 1, print out debugging messages as error tables
972are added and removed from the com_err library. If the
973COMERR_DEBUG_FILE environment variable is set (and the process is not
974setuid) the debugging messages may be redirected to a file.
975
976Change all of the e2fsprogs programs to use the newer add_error_table()
977and remove_error_table() interfaces instead of the much older
978initialize_*_error_table() function.
979
980Add TDB support into the ext2fs library. This allows us to have a
981guaranteed library we can count on always being present so we can
982store data in an on-disk database.
983
984Add support for using TDB to store the icount data, so we don't run out
985of memory when checking really large filesystems.
986
Theodore Ts'od7b64722007-06-24 17:32:47 -0400987Change the regression test suite so that it skips empty test directories.
988
989Define the l_i_iversion field in ext2_inode. The l_i_version field is
990now defined from the old l_i_reserved1 field in the ext2 inode. This
991field will be used to store high 32 bits of the 64-bit inode version
992number.
993
994Add Makefile production rule for e2fsprogs.spec in case it gets
995deleted.
996
997Add new function profile_get_uint() to allow for a clean way to fetch
998unsigned integers from the context.
999
1000Add test to make sure the ext2 superblock structure is 1024 bytes.
1001
1002Fix typo in name of f_dup4 regression test
1003
1004Add new function blkid_gc_cache() which performs a garbage collection
1005pass on the /etc/blkid.tab file.
1006
1007The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
1008general, only e2fsck (after the filesystem is clean), tune2fs, and
1009resize2fs should change the backup superblocks by default. Most
1010callers of ext2fs_open() should not be touching any superblock fields
1011which require the backups to be touched.
1012
1013Add new function to libext2fs, ext2fs_default_journal_size(), which
1014returns the default journal size.
1015

Theodore Ts'o6c094752006-05-29 11:47:25 -04001017E2fsprogs 1.39 (May 29, 2006)
1018=============================
Theodore Ts'o34a26112006-03-29 20:40:23 -05001019
Theodore Ts'o34a26112006-03-29 20:40:23 -05001020Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
1021between 2**31 and 2**32 blocks.
1022
Theodore Ts'o34a26112006-03-29 20:40:23 -05001023Change mke2fs to use /etc/mke2fs.conf as a configuration file to
1024configure the filesystem features, blocksize, and inode_ratio for
1025different filesystem types.
1026
Theodore Ts'o6c094752006-05-29 11:47:25 -04001027Mke2fs will now create filesystems hash trees and on-line resizing
1028enabled by default, based on the new /etc/mke2fs.conf file.
1029
Theodore Ts'o34a26112006-03-29 20:40:23 -05001030The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
1031filesystem device node in exclusive mode to prevent accidents by
1032system administrators. In the case of resize2fs and mke2fs, it will
1033only use exclusive mode if the filesystem is not mounted.
1034
1035Fixed a bug in mke2fs which caused it to to fail when creating the
1036resize inode for large filesystems. (Addresses Debian Bug #346580)
1037
Theodore Ts'obae55642006-05-14 17:31:48 -04001038When allocating space for the RAID filesystems with the stride
1039parameter, mke2fs will now place each portion of the group's inode
1040table right up after the superblock (if present) in order to minimize
1041fragmentation of the freespace.
1042
1043Speed up mke2fs and e2fsck by writing inode and block bitmaps more
1044efficiently by writing the inode and block bitmaps in one pass, thus
1045reducing the number of disk seeks required.
1046
Theodore Ts'o34a26112006-03-29 20:40:23 -05001047Add support for on-line resizing to resize2fs.
1048
1049Fix blkid library so that logic to determine whether or not a device's
1050cached information in /etc/blkid.tab needs to be verified or not
1051doesn't get confused by a system clock which is insane (for example,
1052if the battery is dead on a Macintosh running PPC Linux. (Addresses
1053Red Hat Bug: #182188)
1054
1055The blkid library will now store the UUID of the external journal used
1056by ext3 filesystems, so that in the future, the userspace mount binary
1057can use this to find the location of the external journal and pass
1058this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -05001059
1060E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -05001061control how various options should be handled. See the e2fsck.conf
1062man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -05001063
Theodore Ts'o34a26112006-03-29 20:40:23 -05001064E2fsck now prints an explanatory message when delaying a filesystem
1065check when the system is running on battery. (Addresses Debian Bug:
1066#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001067
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001068E2fsck will detect if the superblock's last mount field or last write
1069field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -05001070#327580) These problems will be fixed automatically in preen mode
1071since Debian's boot sequence bogusly doesn't set the time correctly
1072until potentially very late in the bootup process, and this can cause
1073false positives which will cause users' systems to fail to boot.
1074(Addresses Debian Bugs #343662 and #343645)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001075
Theodore Ts'o34a26112006-03-29 20:40:23 -05001076E2fsck now checks to see if the superblock hint for the location of
1077the external journal is incorrect, and if so, offer to update it.
1078(Addresses Debian Bug: #355644)
1079
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001080Fix e2fsck from segfaulting on disconnected inodes that contain one or
1081more extended attributes. (Addresses Debian Bug: #316736, #318463)
1082
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001083E2fsck will stop and print a warning if the user tries running a
1084read/write badblocks test on a read-only mounted root filesystem.
1085
Theodore Ts'obae55642006-05-14 17:31:48 -04001086Fix a memory leak in e2fsck's error paths. (Thanks to Michael
1087C. Thompson for pointing these out; they were originally found using
1088Coverity.)
1089
Theodore Ts'of3227852005-12-31 16:45:29 -05001090When resizing a file containing a filesystem, resize2fs will expand or
1091truncate a file as necessary. (Addresses Debian Bug: #271607)
1092
Theodore Ts'obae55642006-05-14 17:31:48 -04001093Resize2fs will now automatically determine the RAID stride parameter that
1094had been used to create the filesystem, and use that for newly created
1095block groups. The RAID stride parameter may also be manually specified
1096on the command line using the new -S option to resize2fs.
1097
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001098Fix mke2fs so that it correctly creates external journals on
1099big-endian machines (such as a S/390).
1100
Theodore Ts'obae55642006-05-14 17:31:48 -04001101Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
1102fail to print out the journal or hash seed UUID. (Thanks to Guillaume
1103Chambraud for pointing this out.)
1104
1105Dumpe2fs will now print the size of the journal (if present).
1106
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001107Fix debugfs's set_inode_field command so it can properly set the frag,
1108fsize, uid_high, gid_high, and author fields in the inode instead of
1109silently failing, and so that setting the i_size actually sets i_size
1110correctly.
1111
1112Add a new debugfs command, set_current_time, which sets fs->now so
1113that regression test suites can repeatedly modify the filesystem's
1114last_write fields.
1115
Theodore Ts'o34a26112006-03-29 20:40:23 -05001116Fix a bug in debugfs's icheck which would incorrectly report the owner
1117of an extended attribute block.
1118
Theodore Ts'obae55642006-05-14 17:31:48 -04001119Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
1120print a usage message when an illegal option character is given.
1121
Theodore Ts'o6c094752006-05-29 11:47:25 -04001122Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
1123so it won't core dump. (Addresses SourceForge bug #1424311)
1124
Theodore Ts'obae55642006-05-14 17:31:48 -04001125Fix mklost+found so that it creates a full-sized directory on
1126filesystems with larger block sizes.
1127
1128Fix a file descriptor leak in blkid library.
1129
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001130Fix a display bug in "badblocks -sv" so that the done message properly
1131clears the block number at the end of the test. (Addresses Debian Bug
1132#322231)
1133
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001134Allow fractional percentages to the -m option in mke2fs and tune2fs
1135(Addresses Debian Bug: #80205)
1136
1137Use fstat/fstat64 in getsize.c if the the target is a regular file,
1138instead of attempting to do a binary search. Fix some fd leaks in
1139error cases.
1140
Theodore Ts'o34a26112006-03-29 20:40:23 -05001141Add support for device mapper library to the blkid library to ensure
1142that the "best" (i.e., leaf) device is probed by the blkid library.
1143
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001144Fix the blkid library so that it notices when an ext2 filesystem is
1145upgraded to ext3.
1146
1147Improve the blkid's library VFAT/FAT detection; it now understands
1148labels stored in the root directory, and is more paranoid about
1149checking the FAT superblock values.
1150
Theodore Ts'o34a26112006-03-29 20:40:23 -05001151Fixed a fd leak in the uuid library which was causing problems for the
1152LVM tools. (Addresses Debian Bug: #345832)
1153
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001154Add support for the reiser4 and software suspend partitions to the
1155blkid library. Also add support for extract the label from iso9660
1156filesystems.
1157
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001158Fix a compile_et bug which miscount the number of error messages if
1159continuations are used in the .et file.
1160
1161Add extra sanity checks to protect users from unusual cirucmstances
1162where /etc/mtab may not be sane, by checking to see if the device is
1163reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
1164#319002)
1165
Theodore Ts'o34a26112006-03-29 20:40:23 -05001166Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
1167Bug: #343149, #341911, #300871, #316604, #316782, #330789)
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001168
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001169Fix use-after-free bug in e2fsck when finishing up the use of the
1170e2fsck context structure.
1171
Theodore Ts'o34a26112006-03-29 20:40:23 -05001172Fixed spelling mistakes, typos, and otherwise clarified man pages and
1173documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

1183Programmer's notes:
1184-------------------
1185
Theodore Ts'o7e2ec012006-04-22 04:29:16 -04001186Update config.guess and config.sub to latest version (2006-02-23) from
1187FSF.
1188
1189Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
1190Bugs: #360661, #360317)
1191
Theodore Ts'o34a26112006-03-29 20:40:23 -05001192Fixed the Makefile so that they work correctly on newer versions of
1193GNU make (i.e., 3.81).
1194
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001195Add valgrind support to the regression test suites, and eliminate
1196false positives from valgrind.
1197
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001198Add a regression test suite for the blkid library.
1199
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001200Fix a fencepost error in resize2fs caught by valgrind.
1201
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001202Fix compiler warnings about missing memcpy prototypes.
1203
1204We no longer have the sparc assembly code in the header file any more,
1205so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
1206break compiles on the sparc architectures when using gcc.
1207
1208In the libext2fs library, add the new field fs->now which if non-zero
1209is used instead of the system time when setting various filesystem
1210fields (last modified time, last write time, etc.)
1211
1212Fix gcc 4.01 complaints by adding a missing #include <string.h> to
1213ext2fs.h which is needed since the inline functions use memcpy().
1214(Addresses Sourceforge Bug #1251062)
1215
1216Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
1217the build system when building files in the util directory which are
1218needed during the build process. This avoids potential problems when
1219cross-compiling and some of the options specified in CFLAGS or LDFLAGS
1220are not recognized as valid by the host compiler. (Addresses
1221Sourceforge Bug #1261547)
1222
1223Clean up the blkid library by making the superblock and generic i/o
1224functions to be more generic. Clean up interface to the probe
1225function, and fix memory leak. Finallly, remove an unneeded reference
1226to probe.h in the lib/blkid/resolve.c
1227
Theodore Ts'o3285a9c2005-12-10 23:05:30 -05001228Add an ext2fs_read_bb_FILE regression test to confirm proper detection
1229of invalid block #'s.
1230
Theodore Ts'o34a26112006-03-29 20:40:23 -05001231The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
1232indicate that the the function read/writes the memory location.
1233
Theodore Ts'o3285a9c2005-12-10 23:05:30 -05001234Fix various gcc -Wall complaints.
1235
1236Add a dependency to make sure that the subdirectories are created
1237before creating all of the object files, in order to address parallel
1238build problem in the library Makefiles. (Addresses Sourceforge Bug:
1239#1261553)
1240
1241Add $(LDFLAGS) to the command line argument when generating an ELF or
1242Solaris shared library, to allow cross-compile and other builds that
1243might need to specify -L paths to needed libraries. (Addresses
1244Sourceforge Bug #1261549)
1245
Theodore Ts'obae55642006-05-14 17:31:48 -04001246Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
1247intended for testing purposes. It allows an ext2/ext3 developer to
1248create very large filesystems using sparse files where most of the
1249block groups are not initialized and so do not require much disk
1250space. Eventually it could be used as a way of speeding up mke2fs and
1251e2fsck for large filesystem, but that would be best done by adding an
1252RO_COMPAT extension to the filesystem to allow the inode table to be
1253lazily initialized on a per-block basis, instead of being entirely
1254initialized or entirely unused on a per-blockgroup basis.
1255
Theodore Ts'o6c094752006-05-29 11:47:25 -04001256Fix backwards compatibility so e2fsprogs will better compile on Linux
12572.0.35 systems.
1258
1259Make test scripts more robust against locale-related environment variables
1260
1261Fix type warning problem with sizeof() in ext2fs_open2().
1262
1263Fix type warning problem with time_t in debugfs.

Theodore Ts'o1f965c82005-06-30 20:06:45 -04001267==============================
1268
1269Fix blkid's test programs (built with "make check") compile correctly
1270even without "configure --enable-blkid-debug".
1271
1272Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
1273type aliasing rules on newer gcc compilers. (Addresses Red Hat
1274Bugzilla ##161183.)
1275
1276Fix com_err library to make it more compatible with recent changes
1277made to the com_err library in MIT Kerberos V5 version 1.4.
1278(Addresses Sourcefroge Bug #1150146)
1279
1280General cleanup of messages printed by e2fsprogs programs for grammar,
1281consistency, and to make life easier for translators. Fixed a few
1282strings containing English that had not been marked as needing
1283translations. Removed strings that do not need to be translated, to
1284make life easier for translators.
1285
1286Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
1287test to see if a device appears to be in use instead of just relying
1288on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
1289
1290Fix portability problem in the filefrag program affecting platforms
1291where the size of an integer is smaller than the size of a long.
1292(Addresses Debian Bug #309655)
1293
1294Mke2fs will now use a larger journal by default for filesystems
1295greater than 4GB. (128 MB instead of 32MB).
1296
1297Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
1298unless forced. This is to avoid signed vs. unsigned kernel bugs in
1299block numbers that still need to be fixed.
1300
1301The blkid program has a new option which will more efficiently search
1302for device when it is known (or expected) that only one matching
1303device will be found in the system, such as when doing a lookup by
1304UUID.
1305
1306Debian's e2fsprogs-specific initrd fragment will avoid including
1307unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
1308and LD_LIBRARY_PATH, and filtering out libraries found in
1309/etc/ld.so.preload. (Addresses Debian Bug: #304003)
1310
1311Fixed a potential portability issue in the blkid programs for
1312architectures where the char type is unsigned. (Addresses Sourceforge
1313Bug: #1180585)
1314
1315Fix a bug in filefrag so that it doesn't falsely count an extra
1316discontinuity when the first block found is an indirect block.
1317(Addresses Debian Bug #307607).
1318
1319Fix blkid's recognition of cramfs filesystems, and enhance it to be
1320able to handle cramfs labels.
1321
1322Fix debugfs's stat command to not core dump when a filesystem is not
1323open.
1324
1325Fix e2fsck's handling of error conditions caused by the resize inode
1326claiming blocks that are also used by other inodes, a filesystem
1327corruption which was commonly caused by a bug in Fedora Core 3's
1328resize2fs program.
1329
1330Fixed bug in filefrag which caused it to fail on non-ext2/3
1331filesystems. (Addresses Debian Bug: #303509)
1332
1333If the superblock last mount time indicates that the system clock may
1334not be accurate, then e2fsck will omit checking inodes' deletion time
1335field for indications of a potential corrupted orphaned inode list.
1336(Previously e2fsck only ommited these LOW_DTIME checks when the
1337superblock's last write time looked insane.)
1338
1339Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
1340(Addresses Debian bug #302200)
1341
1342Make the blkid library more paranoid about being run from setgid
1343programs, and to use __secure_getenv() from libc if it is available.
1344
1345Fixed spelling mistakes, typos, and otherwise clarified man pages.
1346(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
1347and Sourceforge Bug: #1189803)
1348
1349Updated and fixed translations.
1350
1351Fixed various Debian packaging issues --- see debian/changelog for
1352details.
1353
1354Programmer's notes:
1355-------------------
1356
1357Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
1358changed to take an unsigned int for the bit number. Negative bit
1359numbers were never allowed (and didn't make any sense), so this should
1360be a safe change. This is needed to allow safe use of block numbers
1361greater than or equal to 2**31.
1362
1363The compile_et program will avoid recreating generated foo_err.c and
1364foo_err.h files if no changes are necessary. The compile_et program
1365will also atomically replace these files to avoid a potential parallel
1366build race problem on SMP systems. (Addresses Sourceforge Bug:
1367#1157933)
1368
1369Added a new function to the blkid library, blkid_probe_all_new(),
1370which only probes newly added disk devices, and change
1371blkid_find_dev_with_tag() to use this function so that when a
1372requested tag is not found, devices that were previously not checked
1373are searched before searching all devices in the system.
1374
1375Added new functions to the blkid library, blkid_dev_set_search() and
1376blkid_dev_has_tag().
1377
1378E2fsck's problem strings can now use @m and @n as abbrevations for
1379"multiply-claimed" and "invalid", respectively.
1380
1381The e2fsprog.pot file now has an explanation of how the @-expansion
1382and %-expansion works, and strings in e2fsck/problem.c which contain @
1383characters now have comments in e2fsprogs.pot with the @-expansion to
1384make life easier for translators.
1385
1386Fixed missing return values in the ext2fs library which could cause it
1387to return random garbage in certain error conditions.
1388
1389Allow the current time to be overriden via the E2FSCK_TIME environment
1390variable for use in regression tests.
1391
1392The test scrpit driver program now exits with a non-zero status if
1393there any of its test that it ran failed.
1394
1395Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
1396Bug: #1157933)
1397
1398Fixed "make check" so that it compiles correctly even when e2fsprogs'
1399header files have not be installed in the system include directories.
1400(Addresses Sourceforge Bug: #1180572)
1401
1402Fixed gcc -Wall nits.

1404
Theodore Ts'ofd4b28e2005-03-21 22:37:03 -05001405E2fsprogs 1.37 (March 21, 2005)
1406===============================
1407
1408Add support for checking the validity of Extended Attributes stored in
1409inodes to e2fsck.
1410
1411Add support for dumping the contents of large inodes to debugfs,
1412including the extended attributes stored in inodes.
1413
1414Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1415when we create a new inode we make sure that the extra information in
1416the inode (any extra fields in a large inode and any ea-in-inode
1417information) is initialized correctly. This can take place when
1418mke2fs creates the root and lost+found directory, when e2fsck creates
1419a new root inode or a new lost+found directory, and when the user uses
1420the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1421create inode could inherit garbage (or old EA information) from a
1422previously deleted inode.
1423
1424Fixed a bug in e2fsck so it would notice if a file with an extended
1425attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1426to zero.
1427
1428Added support to filefrag to detect files which are using the new
1429experimental file extents format, and use the non-ext2 algorithm in
1430that case. Fixed a bug to avoid reporting a false discontinuity if
1431there is one or more unallocated blocks at the beginning of a file.
1432
1433Duplicated a check for noticing whether or not the number of blocks
1434(given a certain blocksize) is greater than 2**32 when the
1435BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1436allows mke2fs to automatically use a larger blocksize when creating a
1437filesystem on a very large device when run on systems that do not
1438support BLKGETSIZE64.
1439
1440Fix the I18N build which was broken in e2fsprogs 1.36 because the
1441build system had been switched to treat the .gmo files as shipped
1442files (for backwards compatibility with systems that have older GNU
1443I18N tools installed), but the gen_tarball.in script was still
1444removing the .gmo files from the official source distribution.
1445
1446Fixed various Debian packaging issues --- see debian/changelog for
1447details. (Addresses Debian Bugs ##296769, #299341)
1448
1449Programmer's notes:
1450-------------------
1451
1452Added new functions to the e2p library which convert between a string
1453and os_type: e2p_os2string() and e2p_string2os(), and used them to
1454make the generated binaries more compact.
1455
1456Fixed a compile-time error on Darwin systems.
1457
1458Cleaned up the lib/ext2fs Makefile slightly.
1459
1460
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001461E2fsprogs 1.36 (February 4, 2005)
1462=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001463
1464All of the patches that were applied to Fedore Core 3's
1465e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1466lot of bug fixes first. Users of Fedora Core 3 are strongly
1467encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1468
1469Add support for filesystem with the online resizing via resize inode
1470feature. Fixed numerous bugs from the Fedora patches. The Fedora
1471patches also didn't bother to do any consistency checking on the
1472resize inode, or add any tests to the regression test suite. The "-R
1473resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1474being listed in mke2fs's usage message. All of these shortcomings
1475have been corrected.
1476
1477E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1478program. In order to do this, the user must run the commands:
1479
Theodore Ts'od0a3b462005-05-05 22:57:44 -04001480 debugfs -w /dev/hdXXX -R "features ^resize_inode"
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001481 e2fsck -f /dev/hdXXX
1482
1483Optionally, the ext2prepare command can be used to re-enable online
1484resizing after the filesystem has been fixed.
1485
1486The fsck program will now accept an optional filedescriptor argument
1487to the -C option. (The Fedora version of this patch would sometimes
1488cause fsck to ignore a parameter on fsck's command line in some rare
1489cases, sigh.)
1490
Theodore Ts'odc256972005-01-26 13:20:12 -05001491Make sure e2fsprogs doesn't write garbage into the reserved portion of
1492large inodes.
1493
1494Make sure resize2fs releases the blocks belonging to the old inode
1495table blocks when moving the inode table. (Addresses Debian Bug:
1496#290894)
1497
1498Skip the r_resize_inode test if resize2fs is not compiled (due to
1499configure --disable-resizer)
1500
1501E2fsck now checks the summary filesystem accounting information, and
1502if any of the information is obviously wrong, it will force a full
1503filesystem check. (Addresses Debian Bug #291571)
1504
1505Fix e2fsck to not complain when the resize_inode feature is enabled,
1506s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1507the resize inode.
1508
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001509Fix e2fsck to note delete symlinks that contain an extended attribute
1510after the ext_attr feature flag has been cleared. (Addresses Red Hat
1511Bugzilla #146284).
1512
Theodore Ts'odc256972005-01-26 13:20:12 -05001513Add new utility program, copy_sparse.c, which is very useful
1514for dealing with large sparse files (such as e2image files).
1515
1516Add support for jnl_blocks[] for debugfs's set_super_value.
1517
1518Fix filefrag so that it works correctly with sparse files.
1519
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001520Filefrag -v will print first and last blocks.
1521
Theodore Ts'odc256972005-01-26 13:20:12 -05001522Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1523and dumpe2fs.
1524
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001525Add mke2fs support so that it can support filesystems larger than 4TB
1526automatically, by retrying with a 4k blocksize if the device size is
1527too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1528bug #1106631)
1529
Theodore Ts'odc256972005-01-26 13:20:12 -05001530Change blkid to test for NTFS first because Windows sometimes doesn't
1531clear enough of the parition to confuse the probing routines into
1532thinking the old filesystem type is still valid. (Addresses Debian
1533Bug #291990)
1534
Theodore Ts'o66fa0de2005-01-11 14:39:55 -05001535Add support for swap partition label and uuid's in the blkid library.
1536
Theodore Ts'odc256972005-01-26 13:20:12 -05001537Add support to the blkid library to recognize Oracle ASM volumes.
1538
1539Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001540not just the first one, and work more consistently when the blkid
1541cache file is not available or set to /dev/null. (Addresses Debian
1542Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -05001543
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001544Badblocks will now correctly display block numbers greater than
1545999,999,999 in its progress display.
1546
1547The tune2fs program will not allow the user from setting a ridiculous
1548number of reserved blocks which would cause e2fsck to assume the
1549superblock was corrupt. E2fsck's standards for what is a ridiculous
1550number of reserved block has also been relaxed to 50% of the blocks in
1551the filesystem.
1552
1553The blkid library will return vfat in preference to msdos, and ext3 in
1554preference to ext2 (if the journalling flag is set) so that mount will
1555do the right thing. (Addresses Debian bug #287455)
1556
1557Mke2fs will now use the -E option for extended options; the old -R
1558(raid options) option is still accepted for backwards compatibility.
1559Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1560
1561Mke2fs will now accept a size in megabytes, gigabytes, and other units
1562(via "32m" or "4g" on the command line) if the user finds this more
1563convenient than specifying a block count.
1564
1565Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1566cache conherency problem.
1567
1568Debugfs now supports a new command, set_inode_field, which allows a
1569user to manually set a specific inode field more conveniently, as well
1570as set entries in the indirect block map.
1571
1572Debugfs's set_super_value command has been enhanced so that the user
1573can set most superblock fields, including the date/time fields and
1574some of the more newsly added superblock fields.
1575
1576E2fsprogs programs now accept an offset to be passed to the file
1577specifiers, via the syntax: "/tmp/test.img?offset=1024".
1578
1579E2fsprogs programs will now accept blocksizes up to 65536; kernel
1580support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001581other architectures with page sizes greater than 4k. There are 2.6
1582kernel patches out there which enable this, but they are of this
1583writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001584
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05001585The e2image command now takes the -s option which will scramble
1586directory entries for raw image files.
1587
1588Fix a file descriptor leak in the filefrag program.
1589
1590Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1591present.
1592
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001593Fix bug in debugfs where kill_file would lead to errors when deleting
1594devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1595
1596Fix bug in the blkid library when detecting the ocfs1 filesystem
1597
1598Remove obsolete EVMS 1.x and a.out DLL support.
1599
1600E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -04001601
1602Fixed two potential ordering constraint problems in e2fsck which might
1603cause the filesystem to be corrupted if e2fsck is interrupted during a
1604(extremely narrow) race window. Thanks to Junfeng Yang from the
1605Stanford Metacompilation group for pointing this out.
1606
1607Fixed bug in e2fsck where it would not accurately detect whether or
1608not the system is running on adaptor if the ACPI device representing
1609the AC adapter didn't correspond to the what was used on IBM
1610Thinkpads.
1611
1612Change e2fsck to accept directories greater than 32MB.
1613
1614Fix e2fsck so that a checkinterval of zero disables a time-based check
1615of the filesystem.
1616
1617Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
1618to the PAGER environment variable. (Addresses Debian Bug #239547)
1619
1620Tune2fs will not mark rewrite the superblock if the feature bitmasks
1621are not modified.
1622
1623The debugfs program will set the filetype information when creating a
1624link.
1625
1626Add debugfs -d option to use a separate source of data blocks when
1627reading from an e2image file.
1628
1629Add e2image -I option which allows the e2image metadata to be
1630installed into a filesystem.
1631
1632Fixed bug in the badblocks program which caused "done" to always
1633appear in english even when a translation was available. (Addresses
1634Debian Bug #252836)
1635
1636The blkid program has a new option -o which controls the output format
1637of the blkid program; this is makes blkid more convenient to use in
1638shell scripts.
1639
1640Fix a minor bug in uuid library, which was not using the full 14 bits
1641of clock sequence when generating UUID's.
1642
1643Fix a Y8.8888K problem in the uuid library.
1644
1645Logsave now creates a new session id for itself to avoid getting
1646killed by init whan transitioning between init levels.
1647
1648Change the licensing of the UUID library to be the 3-clause BSD-style
1649license; this allows Apple to use the uuid library in Darwin.
1650
1651Add ocfs and ocfs2 probe support into the blkid library.
1652
1653Fix a memory and file descriptor leak in the blkid library.
1654
1655The blkid library will revalidate the device if the system time is
1656earlier than last verification time of the device, since that
1657indicates that the system time is probably nottrustworthy.
1658
1659The blkid library will override the default location of the blkid.tab
1660file by the BLKID_FILE environment variable, if it is available.
1661
1662Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
1663
1664Add various portability fixes for lame new versions of glibc, Darwin
1665and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001666Bugs #239934, #264630, #269044, #255589, #289133)
1667
1668Add support for Windows 9x/NT under Cygwin.
Theodore Ts'o48301122004-09-19 08:23:41 -04001669
1670Updated and clarified various man pages. (Addresses Debian Bugs #236383,

Theodore Ts'o48301122004-09-19 08:23:41 -04001672
1673Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
1674
1675Update the rpm spec files so that it works better with Fedora core 2
1676and RH9.
1677
1678Fixed various Debian packaging issues (see debian/changelog). In
1679particular, fixed the Debian initrd scripts. (#241183, #248050,
1680#253595, #247775)

1683Programmer's notes:
1684-------------------
1685
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001686Fixed various gcc -Wall warnings.
Theodore Ts'o48301122004-09-19 08:23:41 -04001687
1688The uuid library now has new functions uuid_unparse_upper() and
1689uuid_unparse_lower() which forces the case of the hex digits to be
1690upper case, or lower case.
1691
1692The build process has been speeded up by enhancing the subst program
1693to update the modtime on the generated files even when the generated
1694file hasn't changed.
1695
1696The uuid library now uses C99 stdint.h types instead of custom types.
1697
1698Updated config.guess and config.sub with newer versions from the FSF.
1699
1700Removed out of date .cvsignore files from the source distribution.
1701
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001702The ext2fs_unlink() function will return an error if both the name and
1703inode number are unspecified, to avoid doing something surprising
1704(such as unconditionally deleting the first directory entry).
1705Directory entries are now deleted by coalescing them with the previous
1706directory entry if possible, to avoid directory fragmentation. This
1707is not an issue with the e2fsprogs suite, but may be a problem for
1708some of the users of libext2fs, such as e2tools.
1709
1710Add support for version numbers of the form "1.36-rc1".
1711
Theodore Ts'o48301122004-09-19 08:23:41 -04001712Fix build of mke2fs.static.
1713
Theodore Ts'odc256972005-01-26 13:20:12 -05001714Add basic ext2fs library support for large (EA in inode) inodes.
1715
Theodore Ts'o48301122004-09-19 08:23:41 -04001716The test_io mechanism can now abort after n reads or writes to a
1717particular block. The block is specified by TEST_IO_BLOCK environment
1718variable, and the read/write count by the TEST_IO_READ_ABORT and
1719TEST_IO_WRITE_ABORT environment variables. The block data is now only
1720dumped if the 0x10 bit is set in TEST_IO_FLAGS.
1721
1722UUID_DEFINE() in the uuid library now creates a static variable, with
1723__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
1724be used in header files.
1725
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001726Add support for the install-strip and install-shlibs-strip targets, as
1727suggested by the GNU coding guielines. "make install" no longer
1728strips the binaries which are installed.
1729
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001730Remove support for the --enable-old-bitops configure option which was
1731only for very old sparc systems.
1732
1733Remove support for --enable-clear-htree; this was only needed during
1734the early development of the htree patch.
1735
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001736Use Linux-kernel-style makefile output so it is easier to see compiler
1737warnings.
1738
1739Update gettext files to version 0.14.1.
1740
1741Update to use autoconf 2.5x.
1742
1743Improved support for compiling e2fsprogs under dietlibc.
1744
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05001745Make e2fsprogs portable to Solaris and FreeBSD systems.
1746
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001747Add blkid_verify(), blkid_get_library_version(), and
1748blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -05001749
1750Add pkg-config files for e2fsprogs's libraries.
1751
1752Fix "make uninstall" to so that it removes everything that is installed.
1753
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001754Add a configure --enable-maintainer-mode option which enables the
1755makefile rules to rebuild the configure script from configure.in, and
1756to reubuild the .gmo files in po directory.
1757
1758Drop the sparc assembly bitwise operations; it's less efficient
1759than the GCC 3.4 compile code and triggers compiler warnings on
1760sparc64. Thanks to Matthias Andree for his analysis and suggestions.

Theodore Ts'ob70b1162004-02-28 10:52:35 -05001764E2fsprogs 1.35 (February 28, 2004)
1765==================================
1766
Theodore Ts'o48301122004-09-19 08:23:41 -04001767E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001768preserves the existing badblocks list.
1769
Theodore Ts'o48301122004-09-19 08:23:41 -04001770Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001771
1772E2fsprogs will now deal correctly with symlinks that contain
1773extended attribute information, which can be created using SE Linux.
1774(Addresses Debian Bug #232328)
1775
1776Remove a double longjump into an invalid stack frame bug in e2fsck.
1777(This was during an abort sequence, which normally worked on Linux and
1778caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001779
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001780Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
1781(the NLS library will replace "" with the .po header information).
1782
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001783Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
1784dump due to a division by zero error. (Addresses Debian bug #207082)
1785
Theodore Ts'o151a7162003-12-26 14:04:33 -05001786Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
1787when reconnecting a directory requires creating a lost+found
1788directory. (Addresses Debian bug #219640).
1789
1790Fixed a bug where e2fsck would bomb out if a journal needed to be
1791replayed when using an alternate superblock.
1792
Theodore Ts'o48301122004-09-19 08:23:41 -04001793E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001794if the laptop is running on battery. The next time fsck runs while
1795the system is on the AC mains, or after the grace period is exceeded,
1796the filesystem will be checked. (Addresses Debian bug #205177)
1797
1798E2fsck will inform the user when there are 5 or fewer mounts before a
1799filesystem check will be forced. (Addresses Debian bug #157194)
1800
1801Fix e2fsck's handling of corrupted indirect blocks in the bad block.
1802We now correctly handle the case where there is an overlap between a
1803block group descriptor or a superblock and a bad block indirect block.
1804In the case where the indirect block is corrupted, we now suggest
1805"e2fsck -c".
1806
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001807Fix byte swap bugs in e2fsck that caused the journal backup location
1808in the superblock and symlinks created by SE Linux to be cleared
1809by e2fsck on big-endian machines. (Addresses Debian bug #228723)
1810
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001811E2fsck -c now replaces the current list of bad blocks with the ones
1812found by badblocks.
1813
1814Fix bugs in e2fsck and tune2fs which could cause a core dump if a
1815non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
1816
1817Fix a potential bug in e2fsck which could cause it to core dump when
1818trying to print the location of the backup superblock.
1819
1820Protect against a potential core dump in e2fsck when printing a
1821message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001822
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001823Add support for backing up the journal inode location in the
1824superblock. E2fsck will automatically save the journal information in
1825the superblock if it is not there already, and will use it if the
1826journal inode appears to be corrupted. ext2fs_add_journal_inode()
1827will also save the backup information, so that new filesystems created
1828by mke2fs and filesystems that have journals added via tune2fs will
1829also have journal location written to the superblock as well.
1830Debugfs's logdump command has been enhanced so that it can use the
1831journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001832
1833E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001834
1835Shrink the size of the e2fsck executable by moving some initialized
1836variables to the BSS segment.
1837
1838E2fsck will avoid printing the ^A and ^B characters which bracket the
1839progress bar when stdout and stdin are a tty device instead of a pipe
1840to another program. (Addresses Debian bug #204137)
1841
Theodore Ts'o151a7162003-12-26 14:04:33 -05001842Debugfs's mkdir command will automatically expand the directory if
1843necessary. (Addresses Debian Bug: #217892)
1844
1845Fixed a bug in debugfs so that copying a file from /dev/null uses the
1846correct mode bits. (Addresses Debian Bug: #217456)
1847
1848If the environment variables DEBUFS_PAGER and PAGER are not set,
1849debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -05001850/usr/bin/pager, and then falling back to 'more' and 'less'.
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001851(Addresses Debian bug #221977)
1852
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001853Debugfs will now support 2.6 device numbers where the major or minor
1854number may be larger than 255. (Addresses Sourceforge bug #865289)
1855
Theodore Ts'o48301122004-09-19 08:23:41 -04001856Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
1857
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001858Chattr now stops processing options when it sees '--'. (Addresses
1859Debian bug #225188)
Theodore Ts'o151a7162003-12-26 14:04:33 -05001860
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001861Fix regression tests so they work correctly when e2fsprogs is compiled
1862with configure --disable-htree.
1863
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001864Fix bug in uuid library when there is no network card and the library
1865is generating a time-based uuid. The random MAC address was not
1866correctly generated to be a multicast address.
1867
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001868Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -04001869around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001870
1871Fix bug in badblocks when using O_DIRECT; we need to make sure that
1872we're reading from an offset which is page aligned. For read-only and
1873read-write tests, we try to recover after an error so that we can
1874continue reading on page-aligned boundaries. (Addresses Debian Bug
1875#203713)
1876
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001877Badblocks now checks 64 blocks at a time instead of 16. (Addresses
1878Debian bug #232240)
1879
Theodore Ts'o151a7162003-12-26 14:04:33 -05001880Updated and clarified various man pages. (Addresses Debian Bug

1887Programmer's notes:
1888-------------------
1889
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001890Fixed a build problem so that e2fsprogs would compile with the
1891--enable-profile option to configure selected. (Addresses Sourceforge
1892bug #811408)
1893
1894Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
1895Bugzilla Bug #112448)
1896
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001897Centralize code which calculates the location of the superblock
1898and block group descriptors so that it is in a single library routine.
1899
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001900Added two new functions, ext2fs_file_open2() and
1901ext2fs_inode_io_intern2() which take a pointer to an inode structure.
1902
1903Fix compile_et to output the correct prototype for
1904initialize_xxx_err_table_r() in the header file. (Addresses Debian
1905bug #204332)
1906
1907In the lib/et makefile, make sure com_err.info is deleted on "make clean".
1908
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001909Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
1910present. This is for when we try stuffing an int into void * pointer.
1911
1912Fix type-punning which can cause gcc 3.x to miscompile code by getting
1913confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
1914and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
1915**'. The EVMS code uses an ugly union approach since we don't want to
1916modify the EVMS interfaces.
1917
1918Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
1919aid build process on systems can use invoke GNU make as "gmake".
1920
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001921Added regression testing for mke2fs.
1922
1923Fixed gcc -Wall nitpicks.
1924
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001925Fixed various compiler warnings.
1926
1927Add portability fixes for FreeBSD and for using fsctl under Darwin to
1928support ext2 ioctl's.
1929
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001930
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001931E2fsprogs 1.34 (July 25, 2003)
1932===============================
1933
1934Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
1935a tight loop while waiting for a child fsck to exit in some cases.
1936This burns CPU times which slows down the low-level filesystem check.
1937
1938Added code to mke2fs to assure that the default block size for a
1939filesystem is at least as big as the sector size of the device, if it
1940can be determined.
1941
1942Changed mke2fs and resize2fs to round the default size of a filesystem
1943to be an even multiple of the VM pagesize in order to avoid a Linux
1944kernel bug introduced when the storage of the buffer cache was moved
1945into the page cache.
1946
1947Mke2fs will warn the user when creating a filesystem with journaling
1948and a blocksize greater than 4096. (Addresses Debian bug #193773)
1949
1950Fixed a bug in resize2fs which caused it to fail on filesystems with a
1951non-empty bad block list. Resize2fs now discards any blocks on the
1952badblock list which are no longer part of the filesystem as the result
1953of a filesystem shrink. (Note: this means that shrinking and then
1954enlarging a filesystem is no longer a reversible operation;
1955information about bad blocks in the part of the filesystem which is to
1956be chopped off will be lost.)
1957
1958Changed resize2fs so the user can use prefixes to specify the units of
1959the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
1960and to make the error and informational messages explicitly display
1961the blocksize used by the filesystem, in order to avoid confusion.
1962(Addresses Debian bug: #189814)
1963
1964Added a new debugfs command, dump_unused, which dumps the contents of
1965all unused blocks to stdout. (Useful as an emergency try-to-find
1966deleted data command.)
1967
1968Added a new debugfs command, imap, which prints the location of a
1969specified inode in the inode table.
1970
1971Fixed a bug in the badblocks program which caused it to use one bit of
1972randomness in its non-destructive read/write test, instead of using a
1973full 8 bits of randomness.
1974
1975Added a new option (-t) to badblocks, which allows the user to control
1976the test pattern(s) used when checking a disk.
1977
1978The blkid probe function now more correctly detects UDF filesystems.
1979
1980Fixed a bug in the blkid library which caused it to not update its
1981cache if a filesystem changes from having a label to not having a
1982label.
1983
1984Fixed a bug in the blkid library wihch could avoid an infinite loop
1985in blkid_find_dev_with_tag() if /proc is not mounted and there the
1986/etc/blkid.tab file has not yet been created.
1987
1988Fixed the badblocks program so that the destructive read/write test
1989honors the -c option, and to use O_DIRECT when possible to avoid
1990thrashing the system block buffer cache.
1991
1992Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -04001993 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001994 - Removed testing NYC translation
1995 - Fixed NLS support for message abbrevations in e2fsck
1996 - Remove de-utf.po, since we shouldn't have two versions using different
1997 charset encodings.
1998 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
1999 simplify the statistics reporting in e2fsck.
2000
2001Changed configure.in so that its defaults for *BSD systems no longer
2002build an fsck wrapper, and not to install in /usr/local by default.
2003
2004Fixed some minor spelling errors/typo's in e2fsck and the configure
2005script.
2006
2007Fixed various Debian packaging issues (see debian/changelog).
2008
2009Updated and clarified man pages. (Addresses Debian Bug #195616)
2010
2011Programmer's notes:
2012-------------------
2013
2014Fix gcc -Wall nitpicks.
2015
2016Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
2017NLS support by default. (Added partial workaround for gettext/Darwin
2018incompatibility problems.)
2019
2020Added full MIT KRB5 and Himdall compaibility support to the com_err
2021library and the compile_et program. (Addresses Debian bug #191900)
2022
2023Added the blkid_known_fstype() function to the blkid library, which
2024returns true if it is passed a filesystem type which is recognized by
2025the blkid probing functions.
2026
2027Improved the documentation for the blkid library.
2028
2029Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
2030returns the hardware sector size of a device, if it is available.
2031
2032Added a dependency in the blkid library's .so file to the uuid
2033library, since the former uses the latter. (Addresses Debian bug
2034#194094)
2035
2036Added --with-diet-libc and --disable-evms to the configure script.
2037
2038Fixed a minor memory leak in the badblocks program.
2039
2040Fixed a portability problem in tune2fs --- not all systems have strptime().
2041
2042Fixed a portability problem in debugfs with the use of getopt() more
2043than once. Old-style BSD, new-style BSD, and Linux C libraries all do
2044things differently.
2045
2046Add support Windows support to ext2fs_get_device_size().
2047
2048Added (normally disabled) debugging code to the Unix I/O manager which
2049causes it to disable all userspace caching if the NO_IO_CACHE is
2050defined.
2051
2052Changed the test I/O manager so it can always be linked into e2fsck,
2053mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
2054configure script. The test I/O manager will only print any debugging
2055information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
2056variables are set, which specifies which I/O operations are logged and
2057a block number to watch, respectively. The log messages are sent to
2058stderr by default, unless a filename is specified via the
2059TEST_IO_LOGFILE environment variable.
2060
2061
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04002062E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04002063===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -05002064
Theodore Ts'oba142c12003-04-16 00:59:59 -04002065Added a new utility program, logsave, which captures the output of a
2066command in a log file, even if the containing directory hasn't been
2067mounted yet (in which case the it saves the output in memory until it
2068can write out the logfile). This is useful for capturing the
2069output of fsck during the boot sequence.
2070
2071Fixed some portability problems that were causing problems under
2072the Cygwin32 environment.
2073
2074Mke2fs now interprets a negative number to the -b option as a minimum
2075block size.
2076
2077Fixed a bug in mke2fs which was incorrectly checking the argument to
2078the -g option if the default block size was used. (Addresses Debian
2079bug #188319)
2080
2081Fsck now explicitly ignores tmpfs and devpts, and it will complain if
2082it can not find filesystem checkers for jfs, reseirfs, and xfs.
2083
2084E2fsck now updates the global free block and inode counters from the
2085block group specific counters quietly. This is needed for an
2086experimental patch which eliminates locking the entire filesystem when
2087allocating blocks or inodes; if the filesystem is not unmounted
2088cleanly, the global counts may not be accurate.
2089
2090Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
20912.0 is not yet supported; this only pulled in the bug fixes: fixed
2092possible hangs caused by bugs in calling waitpid, and not setting the
2093pipe to non-blocking mode; also fixed a file descriptor leak; made
2094sure all functions call log entry/exit functions.)
2095
2096Badblocks now flushes its output file as bad blocks are discovered.
2097
2098The uuid library is now more paranoid about assuming the correctness
2099of the /dev/random device; it mixes in a stream of bytes from
2100random/srandom, just in case.
2101
Theodore Ts'o39d38b02003-03-30 23:45:02 -05002102Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04002103maintainer of e2fsprogs. Other various Debian-specific packaging
2104cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05002105
2106Move the source tarball generation functions from the top-level
2107makefile to the util/gen-tarball script.
2108
2109Updated the Turkish .po translation file.
2110
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002111Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05002112it more compatible with com_err libraries from those distributions.
2113
2114Changed dumpe2fs to always display the superblock fields relating to
2115the journalling and/or directory indexing feature even if those
2116features are not enabled.
2117
Theodore Ts'o508d7f32003-03-16 20:41:04 -05002118Updated and clarify copyright statement vis-a-vis alpha releases of
2119e2fsprogs.
2120
2121The ss library will now try to dynamically link to the readline
2122library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04002123the debugfs program now has line editing and history features. The
2124SS_READLINE_PATH environment variable is used to find a readline or
2125readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002126
Theodore Ts'oe5dced72003-03-15 04:28:17 -05002127E2fsck now finds most duplicate filenames (all when rebuilding all
2128directories via the -D option) and offers to delete or rename
2129duplicate filenames/directory entries. (Addresses Debian Bug #176814).
2130
2131Fix bug in e2image. When writing out a raw image file, include data
2132blocks from symlinks that do not store the symlink within the inode.
2133
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002134Fix bug in resize2fs which incorrectly moved the block and inode
2135bitmaps for sparse superblock filesystems and incorrectly marked
2136blocks as in use. (Addresses Debian bug #174766)
2137
2138Added a new shared library, the blkid library, which efficiently
2139allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
2140and UUID filesystem specifiers without needing to search all of the
2141devices in the system. Instead, the device is looked up in a cache
2142file, and then verified to make sure the blkid cache is correct.
2143
2144Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
2145the device name, using the blkid library. (Addresses Debian bugs
2146#166048, #179671)
2147
2148Fsck now supports backslash escapes in /etc/fstab so that \040 can be
2149used for spaces in device labels.
2150
2151Removed 32-bit limitations for debugfs's dump command.
2152
2153If the user specifies a large number of inodes, Mke2fs will
2154automatically adjust the number of blocks per group to find a valid
2155set of filesystem parameters.
2156
2157Add workaround to detect broken MD devices where when some of the
2158underlying devices are marked read-only, writes to the MD device are
2159silently dropped. E2fsck will detect if there is an attempt to run
2160the journal twice, and abort with an error if this is the case.
2161(Addresses IBM Bugzilla bug #1226)
2162
2163E2fsck will print an error if more than one of the -p/-a, -n or -y
2164options are specified.
2165
2166E2fsck will fix HTREE corruptions in preen mode, without stopping the
2167boot process. This is needed because the 2.4 ext2 filesystem
2168accidentally had the INDEX_FL backwards compatibility code removed.
2169
2170Mke2fs no longer creates filesystems with the dir_index flag set by
2171default; the user has to specifically request it.
2172
2173Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04002174#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002175
Theodore Ts'o508d7f32003-03-16 20:41:04 -05002176Created man page for the mk_cmds program (from the libss library).
2177
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002178Programmer's notes:
2179-------------------
2180
2181Fix various gcc -Wall nits.
2182
2183Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05002184successfully under Solaris and Apple/Darwin.
2185
2186Fixed a Makefile dependency to allow building e2fsprogs using parallel
2187make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002188
2189Changes to create a subset distribution which consists only of the
2190et, ss, uuid, and blkid libraries. The configure script and top-level
2191makefile were changed to support working with a subset distribution.
2192
Theodore Ts'oba142c12003-04-16 00:59:59 -04002193Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
2194actually used, and might people who are looking for
2195EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
2196
Theodore Ts'o508d7f32003-03-16 20:41:04 -05002197Updated debian files to fix a number of Lintian warnings.
2198
2199Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002200
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04002201Removed unnecessary libraries from being linked into the fsck, lsattr,
2202chattr, and blkid executables.
2203
Theodore Ts'o38513012002-11-09 15:00:56 -05002204E2fsprogs 1.32 (Nomvember 9, 2002)
2205==================================
2206
2207Fixed a bug in the Unix I/O routines which caused needless writebacks
2208of clean blocks from the unix_io cache (they were erroneously marked
2209as being dirty, so they were getting written back to disk before
2210getting evicted from the disk cache). This was harmless, but it
2211significantly slowed down e2fsck.
2212
2213Made some other minor optimizations to the Unix I/O routines to save a
2214small amount of CPU time.
2215
2216Updated internationalization files.
2217
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002218
Theodore Ts'oae65b292002-11-08 20:08:48 -05002219E2fsprogs 1.31 (Nomvember 8, 2002)
2220==================================
2221
2222Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
2223compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
2224handling for child process that die unexpectly. Add a hack to force
2225mkfs to create filesystems that won't cause problems with hardware
2226that has 2k or 4k minimum blocksize requirements. Read from child
2227processes in non-blocking mode, so that the GUI continues to update.
2228
2229Fix e2fsck so that it returns the appropriate exit code when the root
2230filesystem has been changed, so that system's rc scripts will be told that
2231the system needs to be rebooted.
2232
2233Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
2234was set, some of the descriptor blocks that should have been written
2235out were getting skipped.
2236
2237Changed e2fsck to force out changes to the backup copies of the
2238superblock and block group descriptors when important changes are made
2239to those data structures.
2240
2241Fix a bug where e2fsck could erroneously mark a filesystem as being
2242clean if a check of dirty filesystem is interrupted with a ^C. (Bug
2243introduced in e2fsprogs 1.28.)
2244
2245If journal debuging is enabled using --enable-jbd-debug, the debugging
2246level is now set via the E2FSCK_JBD_DEBUG environment variable.
2247
2248If byteswapping support is disabled using configure --disable-swapfs,
2249skip the tests which depend on byte-swapping, so that "make check"
2250won't bomb out.
2251
2252Lshattr will now display the indexed directory flag. Also, some of
2253the more esoteric compression flags are supressed unless compression
2254support has been enabled.
2255
2256Update man pages.
2257
2258
Theodore Ts'o5d823a42002-11-01 02:13:53 -05002259E2fsprogs 1.30 (October 31, 2002)
2260=================================
2261
2262When resizing a filesystem, and inodes need to moved, resize2fs will
2263update the inode's ctime field, and the mtime field of the containing
2264directories, so that incremental backups using dump/restore will work
2265correctly.
2266
2267In order to avoid spurious errors, e2fsck wil check the last
2268superblock write time to determine whether or not it can safely use
2269the LOW_DTIME checks to determine if there are inodes on the orphan
2270inode linked list that had somehow gotten disconnected. (Addresses
2271Sourceforge bug #620980)
2272
2273Partition in /proc/partitions that being with the string "lvm" are
2274considered real partitions even if they do not end with a number.
2275
2276Fixed a bug in the the uuid generation function, where if /dev/urandom
2277is not present, but /dev/random is, and there isn't sufficient
2278entropy, the get_random_byte function could spin a loop forever.
2279
2280E2fsck, mke2fs, etc. will now reliably notice when image files are
2281mounted using the loopback interface. (Addresses Sourceforge bug
2282#619119)
2283
2284When flushing buffers (as is done by badblocks, for example) check to
2285see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
2286FDFLUSH ioctl which causes the MD device driver which causes confusing
2287syslog messages about obselete ioctl messages. (Addresses Sourceforge
2288bug #545832).
2289
2290Debugfs's write command now checks to see if the destination filename
2291exists before creating it. (Addresses Sourceforge bug #478195.)
2292
2293When installing man pages, search for compressed man pages using all
2294commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
2295
2296Fixed a bug in fsck where multiple filesystems specified on the
2297command were not being checked in parallel due to a logic bug
2298introduced to support the FSCK_MAX_INST environment variable.
2299
2300We have added a new superblock field, s_mkfs_time, which indicates
2301when a filesystem was created. It is set via mke2fs, and printed out
2302by dumpe2fs, but is not actually touched by the kernel.
2303
2304Dumpe2fs has been made more robust by not aborting if there is an
2305error reading the block/inode bitmaps; instead it will still print out
2306the location of the block/inode bitmaps and inode table.
2307
2308Add support for the an alternative block group descriptor layout which
2309allows for on-line resizing without needing to prepare the filesystem
2310in advance. (This is the incomat feature flag meta_bg.)
2311
2312Add support for storing default mount options in the superblock, so
2313that the filesystem can be mounted with specific mount options without
2314needing to specify them on the mount command line or in the /etc/fstab
2315file.
2316
2317Add support for a new inode flag, which is to be used for indicating
2318the top of directory hierarchies for the Orlov block allocator.
2319
2320Fix e2fsck so that if it creates the lost+found directory, it does so
2321with the more apporpriate permissions of 0700. Also change
2322mklost+found so that it also creates the directory 0700.
2323
2324Fixed format bug in e2fsck if NLS is in use.
2325
2326Add a German translation for e2fsprogs's NLS support.
2327
2328Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
2329the beginning of the inode table. This won't matter much, since if
2330there is a bad block at the beginning of the inode table, the root
2331directory won't be available. But at least e2fsck won't crash in this
2332case.
2333
2334Fixed endian problems in the htree code for e2fsck and debugfs.
2335
2336When byte-swapping a filesystem on a PPC architecture, byte-swap the
2337bitmaps since the historical big-endian ext2 variant had byte-swapped
2338bitmaps, and the ext2fs library assumes this. This fixes the
2339regression test suite on PPC machines.
2340
2341Fix e2image so that it handles a bad block in the inode table
2342appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04002343
2344E2fsck now uses a more sophisticated algorithm to salvage corrupted
2345directories that recovers more information in the corrupted directory
2346block.
2347
2348E2fsck now performs additional consistency checks on indexed (HTREE)
2349directories.
2350
2351Fix bug where efsck might get confused about whether a completely
2352empty directory block is an empty leaf block or an interior htree
2353node. This could cause e2fsck to get confused into think that a valid
2354indexed directory was corrupted.
2355
2356E2fsck no longer creates an empty directory entry at the end of a
2357directory block when optimizing a directory. This would cause some
2358earlier versions of the dxdir kernel code to corrupt the directory
2359when attempting to split a node containing an empty directory entry.
2360
2361E2fsck could sometimes in rare circumstances leave the indexed flag
2362set after a small directory was optimized by compressing it instead of
2363indexing it. (This should never happen in real life, since
2364directories that small wouldn't have been indexed, but better safe
2365than sorry.)
2366
2367E2fsck now only updates the master superblock in all cases. This
2368slightly shortens its run time.
2369
2370Ext2ed can deal with directory entries of length 0; previously it
2371would get stuck in an infinite loop.
2372
2373Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
2374specifiers. (Sourceforge patch #613447)
2375
2376Badblocks will now work correctly on read-only devices such as
2377CD-ROM's. (Sourceforge patch #600451)
2378
Theodore Ts'o5d823a42002-11-01 02:13:53 -05002379Updated and clarified man pages. (Addresses Debian bug #167108)
Theodore Ts'od5e78102002-09-30 11:33:36 -04002380
2381
Theodore Ts'oc6633052002-09-24 01:26:50 -04002382E2fsprogs 1.29 (September 24, 2002)
2383===================================
2384
2385Fixed a bug in e2fsck which could corrupt a directory when optimizing
2386it (via the -D option) or rebuiliding the hash tree index with a 1 in
2387512 probability, due to a fence post error.
2388
2389Fixed a bug in the LVM support code which caused LABEL='xxx' not to
2390work correctly.
2391
2392Mke2fs now enables the directory indexing flag by default. (Since
2393this is a compatible feature flag, it's safe to do so.)
2394
2395Tune2fs will support setting the directory indexing feature flag. It
2396will automatically set up the default hash algorithm and hash seed
2397fields in the superblock.
2398
2399If the bone-headed user enters the root filesystem twice in
2400/etc/fstab, the -R option which skips the root filesystem will skip
2401all of them. (Addresses Debian bug #159423). Note! This is not a
2402precedent for dealing intelligently with any other kind of doubled
2403entry in /etc/fstab!
2404
2405
2406Programmer's notes:
2407-------------------
2408
2409Removed perror declaration in lib/et/internal.h. All modern systems
2410can be expected to define perror() these days. Besides, the lib/et
2411code wasn't using perror at all anyway. :-)
2412
2413
Theodore Ts'ob7bad612002-08-31 03:00:33 -04002414E2fsprogs 1.28 (August 31, 2002)
2415================================
2416
2417Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2418for setting the htree flag is not included yet, although it can be
2419manually turned on via the debugfs program.
2420
2421Clarified e2fsck error message which is printed when it cannot find
2422sufficient contiguous block when relcating filesystem metadata.
2423
2424Added support for building an EVMS plugin module for ext2/3. This
2425module is substantially the same as the EVMS module shipping with EVMS
24261.1, with one or two bugfixes. E2fsprogs can also build this plugin
2427for use with EVMS 1.0 (which did not include the ext2 plugin module),
2428if the configure --enable-old-evms flag is given.
2429
2430Fsck will search through EVMS volumes when trying to resolve
2431filesystem specifications such as LABEL=xxx or UUID=xxx.
2432
2433Added a new utility program, /sbin/findfs, which will return
2434filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2435the device name.
2436
2437Update and clarified various man pages. (addresses Debian Bug #145044,
2438#146437, #131350, #151990, #144621, #141938)
2439
2440If there are no filesystems specified on fsck's command line, fsck now
2441treat that as if the -As options were given. Previously it would
2442simply do nothing. (Addresses Debian Bug #153102)
2443
2444Mke2fs no longer treats a failure to be able to clear the MD signature
2445at the end of the filesystem as a fatal error. (Addresses Debian Bug
2446#155007)
2447
2448The e2p library functions (which are used by lsattr and chattr) now
2449double check to make sure the file is a regular file or directory
2450before attempting to use the ext2 ioctls. Some device drivers
2451unfortunately respond to the ext2 ioctl's with unknown behaviour.
2452(Addresses Debian Bug #152029).
2453
2454The extended attribute handling has been updated to correspond with
2455the latest V2 bestbits ACL code.
2456
2457Fixed bug in e2fsck which caused it to not clear the dtime field when
2458processing truncated inodes on the orphan list. This could cause data
2459loss(!) if a filesystem is rebooted before a truncate has been
2460committed.
2461
2462E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2463algorithms. This makes e2fsck much faster in the case of severely
2464corrupted filesystems where a large number of blocks are claimed by a
2465large number of inodes. (Thanks to the 2.5 IDE device driver for
2466inspiring this work.)
2467
2468Resize2fs has been significantly sped up when shrinking and expanding
2469a filesystem by a very small number of blocks (for example, when EVMS
2470is converting a partition to be an EVMS legacy volume).
2471
2472Added a new option to e2fsck, -D, which will optimize or compress all
2473of the directories in the filesystem.
2474
2475E2fsck now catches SIGINT and SIGTERM to make sure it will can
2476properly clean up and only exit at safe points. Fsck will pass
2477SIGINT/SIGTERM to its child processes, and wait until they have all
2478exited before it exits.
2479
2480The uuid parsing code in the uuid library now properly complains when
2481an illegally formated uuid is presented to it. (Addresses Debian bug
2482#152891)
2483
2484Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2485and 2.4.17, since the workaround can cause problems when using a 2.4
2486kernel with an old version of glibc built with the 2.2 headers.
2487
2488Fixed a bug in mke2fs where it wasn't properly clearing the initial
2489superblock used by other filesystems. (Addresses Debian bug #147256.)
2490
2491Added support for the synchronous directory feature written by Andrew
2492Morton.
2493
2494The debugfs program can delete directories using the rmdir command.
2495
2496Add support for 8k and 16k filesystems (for systems with page sizes
2497that are greater or equal to 8k or 16k, respectively). Note that
2498these filesystems can not be mounted on x86 systems, or other systems
2499with only 4k page sizes, due to limitations in the current Linux VM
2500code.
2501
2502Resize2fs requires that the filesystem state be valid and have no
2503errors; otherwise, e2fsck -f must be run first. (Previously it simply
2504required that the last fsck time be greater than the last mount time.)
2505
2506Configure now defaults the man pages directory to /usr/share/man on
2507Linux systems.
2508
2509E2fsck now offers to truncate inodes which contain too many blocks (so
2510that i_blocks would overflow. Also fixed handling of large sparse
2511files.
2512
2513E2fsck now more completely checks for symlink validity, including
2514requiring NULL termination and length checks.
2515
2516E2fsck will offer to try forcing a disk write to remap a bad block
2517after finding a read error when reading a filesystem metadata block.
2518
2519Fixed a bug in debugfs which caused the -b and -s options to crash
2520debugfs, as well as breaking the testb, setb, and clearb functions.
2521
2522Added a bmap command to debugfs which calculates the logical to
2523physical block mapping for a particular inode.
2524
2525Fixed a bug in code which checked to see if a device was mounted which
2526sometimes (rarely) failed in the case of a plain file.
2527
2528Fixed a bug in resize2fs where when it reported an error, it would
2529print a message erroneously indicating that the filesystem had been
2530resized before it aborted.
2531
2532When resizing a plain file which is smaller than the requested size,
2533resize2fs will attempt to extended the file so that programs like
2534e2fsck will not complain that the file is too small.
2535
2536Resize2fs will print the actual new size of the filesystem when it is
2537finished resizing.
2538
2539Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2540information on big-endian systems.
2541
2542
2543Programmer's notes:
2544-------------------
2545
2546Fixed collisions with C++ reserved words.
2547
2548Added portability fixes for building e2fsprogs on the HURD and AIX.
2549
2550Added the ext2ed program for creation of test cases. (ext2ed has many
2551limitations and bugs which make it unsuitable for production use.)
2552
2553The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2554flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2555name_len field is byte swampped on big-endian machines, since in the
2556V2 structure, name_len is a char field which is doesn't need to be
2557byte swapped --- except if an old-style kernel had byte-swapped the
2558name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -05002561E2fsprogs 1.27 (March 8, 2002)
2562==============================
2563
2564The warning messages for mke2fs now go to standard error.
2565
2566Fixed to make sure "make check" runs all of the test programs with
2567LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2568
2569The mke2fs program checks the boot sector for the BSD disk label, and
2570avoids erasing it if it is there.
2571
2572Fixed a bug in e2fsck which caused it to core dump if the journal
2573inode was missing when it was supposed to be there.
2574
2575E2fsck now prints ranges in pass 5 when printing deltas for the block
2576and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002577
2578Debugfs's "ls -l" command now will print out the file type information
2579in the directory entry.
2580
2581Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2582mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2583
2584Debugfs can now examine the experimental directory indexing
2585information.
2586
Theodore Ts'oa471ac52002-03-05 03:37:06 -05002587Fixed bug in debugfs which caused it to core dump if modify_inode is
2588called without an open filesystem.
2589
2590The debugfs lsdel command now runs its output through a pager first.
2591
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002592When installing manual pages, remove the compressed manual pages first.
2593
2594Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2595
2596Fix the 2.4 resource limitation workaround introduced in 1.26 which
2597actually broke things on mips32, sparc32, and Alpha platforms.
2598
Theodore Ts'oa471ac52002-03-05 03:37:06 -05002599Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2600(which is required by the newer libintl libraries).
2601
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002602Programmer's notes:
2603-------------------
2604
Theodore Ts'oa8e77242002-03-08 03:12:14 -05002605Fixed various gcc -Wall complaints.
2606
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002607Fixed a few memory leaks in the e2fsck journaling code, and in the
2608ismounted code checking for a swap device.
2609
2610Add new inode I/O abstraction interface which exports an inode as
2611an I/O object.
2612
2613Exported ext2_file_flush as a public interface.
2614
2615In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
2616
2617Lots of small random portability fixes to make e2fsprogs build under
2618AIX --- even without the 5L compatibility toolkit, and even using the
2619uber-crippled AIX native C compiler.
2620
2621
Theodore Ts'o06987392002-02-03 01:36:54 -05002622E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002623=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002624
Theodore Ts'o446314f2001-12-24 15:22:27 -05002625Dumpe2fs will keep going now if the bad block inode can't be read.
2626(Previously it stopped with a fatal error.)
2627
2628E2fsck will now give an opportunity to run the journal even if the
2629recovery flag is not set. This is the default behaviour if e2fsck is
2630using a backup superblock, since the needs_recovery flag will never be
2631set in the backup superblock copies.
2632
2633E2fsck now automatically finds the backup superblock/group descriptors
2634even when the primary superblock is completely destroyed for 2k and 4k
2635filesystems. (Previously it just guessed/assumed that we were dealing
2636with a 1k filesystem in that case, and users had to manually specify
2637the backup superblock number.)
2638
2639Fixed a bug in e2fsck where it dereferences a null pointer when there
2640is a problem opening a filesystem in preen mode.
2641
2642E2fsck now handles external journals correctly; previously it trashed
2643the external journal device if the journal needed to be replayed.
2644
2645Work around ulimit incompatibility problem caused by recent 2.4
2646kernels; the unix IO module will automatically try to set any resource
2647limits to be infinite on startup.
2648
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002649Fixed a bug in e2fsck where it wasn't allocating a new block or inode
2650bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04002651 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002652
2653E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
2654clearing the new V2 fields if they do not make sense or if the ext3
2655superblock is version 1 superblock.
2656
2657E2fsck will automatically relocate the ext3 journal from a visible
2658file (i.e., /.journal) to an hidden inode if the filesystem has been
2659opened read/write. This allows the users to add a journal while the
2660filesystem is mounted, but the next time the system is rebooted, the
2661journal file will disappear. This avoids problems with backups,
2662stupid operators with superuser bits, etc.
2663
2664Fix a bug in fsck where it would not support a filesystem type of
2665"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
2666
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002667Fsck now supports fstab entries of the form "ext3,ext2". It will also
2668automatically identify reiserfs filesystems.
2669
2670The number of processes spawned by fsck can now be limited using the
2671FSCK_MAX_INST environment variable.
2672
Theodore Ts'o446314f2001-12-24 15:22:27 -05002673Fsck now searchs the LVM proc hierarchy to find logical volumes which
2674should be searched for UUID and label information.
2675
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002676Work around a bug in 2.4.10+ kernels by trying to unset the filesize
2677limit if at all possible, when opening a block device. (The filesize
2678limit shouldn't be applied against writes to a block device.)
2679
Theodore Ts'o446314f2001-12-24 15:22:27 -05002680In mke2fs and e2fsck, specifying the -c option twice will now do
2681a read/write test on the disk. Update the man pages to encourage
2682using the -c option, and to discouraging running badblocks separately,
2683since users tend to forget to set the blocksize when running
2684badblocks.
2685
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002686Mke2fs now automatically clears the immutable attribute on a
2687pre-existing .journal file left over from a previous failed attempt to
2688add a journal to an alreadyy-mounted filesystem.
2689
2690Fixed mke2fs's exit codes to consistently indicate when the mke2fs
2691operation failed.
2692
Theodore Ts'o446314f2001-12-24 15:22:27 -05002693Mke2fs now creates the lost+found directory with permissions of 0700,
2694so that files that had previously lived in protected directory are
2695safe if they get dropped in lost+found and the system administrator
2696doesn't deal with immediately. (Addresses Debian #bug 118443)
2697
2698Mke2fs and e2fsck (and all programs that use the
2699ext2fs_check_if_mounted function) will now properly identify that a
2700device is mounted, even in cases where devfs has confused things with
2701multiple devices names with the same identity, or if a dim-witted
2702system administrator has done something stupid like creating device
2703file aliases in their home directory. Also now checks for swap devices
2704by using /proc/swaps. (Addresses Debian bug #106622)
2705
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002706Added a new option (-T) to tune2fs which sets the time a filesystem
2707was last checked.
2708
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002709Speed up e2image when creating sparse raw image files by optimizing
2710away excess lseek() system calls.
2711
2712Fix support of large (> 2GB) files when used as a filesystem in
2713mke2fs, tune2fs, debugfs, and findsuper.
2714
2715Debugfs's stat and icheck commands now properly deals with large (>
27162GB) files.
2717
2718Debugfs's set_super_value command now prints out the list of valid
2719superblock fields which can be set using the command.
2720
Theodore Ts'o446314f2001-12-24 15:22:27 -05002721Debugfs's rm and kill_file command now updates the superblock free block
2722and inode counts, thus keeping the filesystem consistent.
2723
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002724Debugfs's lsdel command now takes an optional argument which allows
2725the user to only see the most recently deleted files.
2726
2727A new command (undel) was added to debugfs which automates
2728undeleting a deleted inode and linking it back to a directory.
2729
2730Debugfs's ls command now takes a new option, -d, which lists
2731deleted directory entries.
2732
2733Debugfs's testb, freeb, setb, and find_free_block commands now take an
2734optional count argument.
2735
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002736Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
2737be used to signal that a particular inode should not be eligible for
2738tail-merging --- this is needed for programs like LILO.
2739
2740The findsuper (an unreleased, uninstalled utility program) has been
2741improved to add extra validity checks and to add a progress meter.
2742(It is still an unsupported program; the officially supported way to
2743recover from a trashed partition table is to use gpart; findsuper is
2744for wizards only. :-)
2745
2746Debugfs was fixed to compile with "configure --disable-swapfs".
2747
Theodore Ts'o446314f2001-12-24 15:22:27 -05002748Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002749
2750Added new translation file for Turkish.
2751
Theodore Ts'o446314f2001-12-24 15:22:27 -05002752Programmer's notes:
2753-------------------
2754
2755Fix general gcc -Wall complaints.
2756
2757E2fsprogs (mostly) works with the dietlibc.
2758
2759The programming texinfo file has been expanded to include description
2760of additional libext2fs functions. (Still not compeltely done, but a
2761lot of the more important functions have been documented.)
2762
2763Added a umask structure to struct_ext2_filsys, which currently only
2764modifies the behaviour of ext2fs_mkdir(), but if we add any file
2765creation functions to libext2fs, we should also make sure they respect
2766the umask setting.
2767
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002768The build-rpm script was fixed to be a bit more safe.
2769
2770The tests' Makefile now has a way of automating test case creation
2771for e2fsck, using "make testnew".
2772
2773Created a new function, ext2fs_dir_iterate2 which passes more
2774information to the callback function (identical to the one used by
2775ext2fs_dblist_dir_iterate). The directory iterator functions take a
2776new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
2777directory entries. If the directory entry is deleted, the callback
2778function will be called with the entry paraemter set to
2779DIRENT_DELETED_FILE.
2780
2781Added new functions, ext2fs_inode_alloc_stats and
2782ext2fs_block_alloc_stats, which takes updates block/inode allocation
2783statistics in the bitmaps, block group descriptors, and superblock
2784when inodes or blocks are allocated or deallocated.
2785

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04002787E2fsprogs 1.25 (September 20, 2001)
2788===================================
2789
2790This is primarily a bug-fix release; no new features were added, but
2791there are a number of embarassing bug fixes and cleanups applied.
2792
2793Fix a bug mke2fs which causes stack garbage to be written to disk when
2794zapping disk sectors. (This bug could cause mke2fs to core dump for
2795some kernels, I suspect with security enhancement patches.)
2796
2797Remove unneeded #include of <linux/config.h> which was breaking
2798building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
2799
2800Updated tune2fs man page to reflect the fact that adding or removing a
2801journal doesn't require running e2fsck.
2802
2803Remove use of AC_REQUIRE from autoconf which had been used to prevent
2804AC_CANONICAL_HOST from being called twice; unfortunately this causes
2805recent autoconf to bomb out since they don't allow AC_REQUIRE to be
2806used outside of autoconf macros. Fortunately, it doesn't seem to be
2807necessary any more, anyway.
2808
2809E2fsck will now not fall back to an alternate superblock if the user
2810specifies the superblock location explicitly on the command-line.
2811This allows easier recovery from a situation where the primary
2812superblock and block groups are slightly corrupted, but the backup
2813superblocks are completely broken.
2814
2815Fix problem which caused compile_et and mk_cmds to blow up if
2816e2fsprogs was in a directory with a pathname that contained spaces.
2817
2818We are now more paranoid about checking the entry in /etc/mtab to make
2819sure the filesystem is really mounted, since some broken distributions
2820(read: Slackware) don't initialize /etc/mtab before checking non-root
2821filesystems. (Slackware also doesn't check the root filesystem
2822separately, and reboot if the root filesystem had changes applied to
2823it, which is dangerous and broken, but there's nothing I can do about
2824that.)
2825
2826Make UUID library C++ friendly by adding appropriate extern "C"
2827declarations and using const in the function declarations.
2828
2829Fix up the com_err texinfo file so that it can product a valid info
2830file (previously, it could only be used to generate paper
2831documentation using texinfo.tex).
2832
2833
Theodore Ts'ofb707752001-09-04 15:00:37 -04002834E2fsprogs 1.24a (September 2, 2001)
2835===================================
2836
2837Fix brown-paper bug in mke2fs which caused it to segfault when
2838printing the version string.
2839
2840
Theodore Ts'o109624a2001-08-31 00:59:55 -04002841E2fsprogs 1.24 (August 30, 2001)
2842================================
2843
2844Revert the BLKGETSIZE64 support, since for some distributions, this
2845ioctl has been used by an unofficial kernel patch to update the last
2846sector on the disk, and this was causing disk corruption problems as a
2847result.
2848
2849Mke2fs is now more careful about zapping swap space signatures and
2850other filesystem/raid superblock magic values so that programs like
2851mount who try to use hueristics to determine the filesystem type of a
2852partition are less likely to be confused.
2853
2854E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
2855regular file (since Andreas Dilger's on-line resizing tools will set
2856its mode bits).
2857
2858Fixed some minor texinfo, man pages nits for spelling errors,
2859texinfo warnings, etc. (Addresses Debian bug #110621.)
2860
2861E2fsprogs program no longer print the filesystem version number
2862(i.e. 0.5b), since it only confuses people and doesn't serve any real
2863purpose.
2864
2865E2fsck will once again compile under libc5, since it will supply its
2866own version of strnlen if necesssary.
2867
2868mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
2869when specifying the external journal device. tune2fs will also search
2870devices looking for the externla journal debice when removing.
2871
2872E2fsprogs 1.23 (August 15, 2001)
2873================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002874
2875Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04002876correctly handle a filesystem with EA's and check the EA blocks for
2877corruptions.
2878
Theodore Ts'od494bba2001-08-09 06:14:42 -04002879E2fsck's symlink sanity checking has been cleaned up. It now checks
2880the i_size value of fast symlinks, and checks for immutable flags
2881being set of symlinks, etc.
2882
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002883E2fsck now offers to clear inodes which are special files that have a
2884non-zero i_blocks or i_size field. (The i_size field check was in the
2885previous version of the code, but due to a bug it didn't offer to
2886clear the inode unless i_size and i_size_high were both non-zero.)
2887
Theodore Ts'od494bba2001-08-09 06:14:42 -04002888E2image can now create "raw" image files, which only contain the
2889filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
2890debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04002891
2892Add support for the 64-bit block device patches.
2893
2894Fixed bugs in creating external journals with a 1k blocksize.
2895
Theodore Ts'od494bba2001-08-09 06:14:42 -04002896Add initial support for external journals (so long as the external
2897journal only supports a single filesystem) in e2fsck.
2898
2899Remove requirement for needing to run fsck on a filesystem after
2900removing a journal (either internal or external).
2901
Theodore Ts'obf16d102001-07-27 22:20:06 -04002902The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002903
2904Speed up the check of an ext3 filesystems by avoiding a needless flush
2905of all of the superblock and block group descriptors.
2906
Theodore Ts'od494bba2001-08-09 06:14:42 -04002907Speed up creating an internal journal using tune2fs in the case where
2908the filesystem has a lot blocks already allocated.
2909
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002910Tune2fs has been fixed to make sure that only error messages go to
2911stderr, and normal message go to stdout. (Addresses Debian bug #108555)

Theodore Ts'od494bba2001-08-09 06:14:42 -04002913Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002914now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04002915
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002916Add support in fsck for the filesystem type "auto".
2917
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002918Fsck -A will not try to interpret device names for filesystems which
2919have a pass number is 0. (Addresses Debian bug #106696).
2920
2921Fsck prints a warning message if now valid filesystems are passed to
2922it. (Addresses Debian Bug #107458.)
2923
Theodore Ts'o9249d982001-07-20 18:14:10 -04002924E2fsck now gives an explicit warning if there filesystem still has
2925errors at the end of the run. (Addresses Debian bug #104502)
2926
Theodore Ts'od494bba2001-08-09 06:14:42 -04002927E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002928reflects an error. E2fsck will also not run the orphan list if the
2929filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04002930
2931E2fsck now prints the number of large files when given the -v option.
2932
2933Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04002934
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002935Some minor man pages updates. (Addresses Debian bug #30833, #108174)

Theodore Ts'o19d6b542001-06-23 00:13:09 -04002938E2fsprogs 1.22 (June 22, 2001)
2939==============================
2940
2941Fixed a bug in e2fsck's handling of orphan inodes which are special
2942files (i.e., block/character device files, named FIFO's, etc.).
2943
2944Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
2945tune2fs to fail at adding a journal to a mounted filesystem.
2946
2947Fixed a few big-endian bugs in e2fsprogs
2948 * The directory block functions were accidentally reporting
2949 some directories as corrupted when they weren't.
2950 * If e2fsprogs is compiled --disable-swapfs, the C language
2951 equivalents weren't being included for big-endian platforms.
2952 (Fixes Debian bug #101686).
2953
2954Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
2955
2956Programmer's notes:
2957-------------------
2958
2959Use platform independent method of defining the BLKFLSBUF and FDFLUSH
2960ioctls, and allow them to be defined for non-i386 platforms.
2961
2962The uuid.h header file is now protected against multiple inclusions.
2963
2964E2fsprogs is now being developed using BitKeeper. Changed the test
2965scripts to deal with BK's stripping CR characgters from text files,
2966and changed the top-level Makefile.in to avoid including BitKeeper
2967files when generating the source tarball.
2968
2969
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002970E2fsprogs 1.21 (June 15, 2001)
2971==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00002972
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002973Added new configure flags which allow a subset e2fsprogs to be built;
2974this is most useful for boot floopies, since the resulting shared
2975libraries and programs are slimmed down by removing features that
2976aren't necessary for a boot floppy. The new flags that were added
2977are: --disable-swapfs, which removes support for byte swapping old
2978legacy PPC/68k filesystems, --disable-debugfs, which removes support
2979for debugfs from the libext2fs library, --disable-imager, which
2980removes support for the e2image program, and --disable-resizer, which
2981removes support for resize2fs.
2982
2983E2fsck now prints the number of mounts or days elapsed since the last
2984check when e2fsck is forced to check an otherwise clean filesystem.
2985
2986Tune2fs now prints an informative message about how often a filesystem
2987will be checked when adding a journal to the filesystem, to remind the
2988user that he/she may want to adjust those parameters using tune2fs
2989-c/-i.
2990
2991Worked around hurd brain-damage which causes e2fsck to sometimes
2992believe a filesystem is the root filesystem based on device numbers
2993(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
2994violation).
2995
2996Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
2997erroneous error with the -F option was specified.
2998
2999Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003000ext3 0.7a.
3001
Theodore Ts'o767de092001-06-02 01:20:18 +00003002Fixed two bugs in e2fsck's handling of dup block handling, dealing
3003with relatively uncommon edge cases: a directory with an indirect
3004block which is claimed by another file, and when the last inode in the
3005filesystem has blocks claimed by another file.
3006
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00003007E2fsck now checks to see if the i_size field of a fast symlink is too
3008big, and offers to clear the symlink if so.
3009
3010E2fsck now checks to see if i_size_high of special files is non-zero,
3011and offers to clear i_size_high.
3012
Theodore Ts'o767de092001-06-02 01:20:18 +00003013Fix e2fsck's handling of incompatible journal flags so that the user
3014has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00003015entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00003016
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003017Fixed a bug in fsck which could cause it to core dump if a mix of
3018standard and non-standard device names are used in /etc/fstab.
3019(Debian bug #100559)
3020
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003021Fixed a bug in debugfs which caused read errors when copying a file to
3022not be noticed.
3023
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003024The debugfs set_super_value command can now modify the s_lastcheck field.
3025
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003026Fixed a bug in lsattr and chattr which was accidentally introduced in
30271.20 to support > 2GB files; both lsattr and chattr wasn't reading
3028directories correctly because the change modified the layout of struct
3029dirent to be incompatible with the libe2p shared library.
3030
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003031Cleaned up the mke2fs manual page and included a discussion about why
3032it's good to periodically check the filesystem even when journaling is
3033enabled.
3034
Theodore Ts'o767de092001-06-02 01:20:18 +00003035Programmer's notes:
3036-------------------
3037
3038Fix general gcc -Wall complaints.
3039
3040The types needed by the ext2 header files are now provided by
3041lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
3042
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003043Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003044in ext2_types.h. Also, if linux/types.h has already been defined,
3045don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003046
Theodore Ts'o767de092001-06-02 01:20:18 +00003047Fixed make depend script so that it automatically corrects the
3048pathname cleanups performed by make -M, so I don't have to fix them up
3049by hand.
3050
3051Fixed the d_loaddump test case to be more robust, and not depend on
3052bash'isms.
3053
3054Removed debugfs's dependence on pread(), which was accidentally
3055intrudced in e2fsprogs 1.20
3056
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003057Fixed a performance bug in the libext2fs's icount routine; the size
3058estimate of the icount array was incorrectly being calculated.
3059
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003060Removed use of the badblocks compatibility functions in the e2fsprogs
3061programs.
3062
3063Added paranoia code which protects against strange cases where /etc
3064isn't on the root filesystem, or if /etc/mtab doesn't exist.
3065
3066The header file ext2_types.h is now installed.
3067
3068Autoconf is used to determine when we are on big-endian machines,
3069instead of doing run-time tests, to save a few bytes of code.
3070
3071The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
3072functions are no longer inline functions, which saves space and
3073doesn't really cost any real performance.
3074
3075The ext2fs library no longer depends on the e2p library. (What need
3076there was of it --- namely, fsetflags, was coded in-line).
3077
3078Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
3079when the user is stupid and tries compiling the package using "make
3080install" as root.
3081
3082Miscellaneous code cleanups:
3083 * Added missing files from Makefile.in's SRCS file, so that
3084 their dependencies would be properly calculated.
3085 * Removed redundant code
3086 * Fixed comments in code
3087 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00003090E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003091=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00003092
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003093Add support for replaying the ext3 journal purely in user mode,
3094including handling the orphaned inode list. Used code contributed by
3095Andreas Dilger, with bug fixes and the orphaned inode handling done
3096by Theodore Ts'o.
3097
3098The mke2fs and tune2fs programs can create or modify a filesystem to
3099include an ext3 journal. Tune2fs also can be used to remove an ext3
3100journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00003101
3102E2fsck will now check for the existence of a linked list of orphan
3103inodes in the superblock, and clear those inodes before starting the
3104rest of the filesystem check (but after the journal playback).
3105
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003106E2fsck now validates the file descriptor passed to the -C option,
3107which saves against the completion bar getting written to an
3108unexpected location, such as the disk being checked. (Debian
3109bug/wishlist #55220)
3110
3111E2fsck will now bump the filesystem revision number from zero to one
3112if any of the compatibility bits are set.
3113
3114Fixed a bug where a badly corrupted directory on a big endian system
3115could cause e2fsck to die with a bus error. The
3116ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
3117the ext2 library now does alignment sanity checks on the rec_len field
3118of the directory entry before using it.
3119
3120The ext2 library has been enhanced to make tune2fs safe to run on
3121mounted filesystems. (Users could usually get away with using tune2fs
3122on mounted filesystems before, but with the advent of ext3 and
3123journaling, it became important to make tune2fs was *really* safe for
3124use even when the filesystem being modified is mounted.) E2label is
3125now implemented by tune2fs using an argv[0] dispatch, so that e2label
3126is also now safe for use on mounted filesystems.
3127
3128Added a new program, e2image, which creates a backup of critical ext2
3129filesystem data structures. The generated image file can be examined
3130using dumpe2fs and debugfs. In the future, e2fsck will be able to use
3131the image file to help recover very badly damaged filesystems.
3132
3133Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
3134no longer cause e2fsck to bomb out. Also treat files > 2GB as being
3135large file when deciding whether or not the filesystem has large files.
3136
3137Fixed lsattr and chattr so that they work correctly on large files.
3138(Fixes Debian bug #72690.)
3139
3140Removed limitation in get_device_size() which imposed a one terrabyte
3141filesystem limitation. (Most 2.2 kernels still have a signed int
3142problem which cause 1 TB block device limitation. Fortunately, the
3143kernel patches to fix this are much easier than fixing the 2TB
3144limitation in the kernel. :-)
3145
3146A max_mount_count of zero is now treated as if no mount count were
3147set. (Previously, no mount count was indicated by using -1, and a
3148mount count of zero caused e2fsck to always be run.)
3149
Theodore Ts'o77648562001-05-14 13:04:44 +00003150Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003151
3152Mke2fs now adds some randomness in s_max_mount_count so that multiple
3153filesystems won't be all checked at the same time under normal
3154operations.
3155
Theodore Ts'o5570a652000-08-21 01:23:39 +00003156Fixed bug in the progress bar printing code which could cause e2fsck
3157to core dump on an illegal filesystem.
3158
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003159Fixed bug in fsck which could allow more than one instance of e2fsck
3160to be printing a progress bar. (Debian bug #65267)
3161
Theodore Ts'o5570a652000-08-21 01:23:39 +00003162Fsck using a UUID or a LABEL specifier will work even if devfs is
3163compiled into the kernel and not mounted. If the pathnames in
3164/proc/partitions are incorrect, fsck will search /dev for the correct
3165device (using the new ext2fs_find_block_device library function).
3166Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003167found when they are in use. Support has also been added to support
3168additional IDE disks and the DAC 960 device names. (Debian bug #94159)
3169
3170Fixed a bug in fsck which caused it not deal properly with 16
3171byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00003172
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00003173Fsck's -t option has been made a lot more flexible. The semantics for
3174what happens if a comma-separated list to fsck has been regularized,
3175and it is now possible to filter what filesystems will get checked
3176based what is in the filesystem's fstab entry's option field. (Debian
3177bug #89483.)
3178
Theodore Ts'o5570a652000-08-21 01:23:39 +00003179The dumpe2fs program can now print out the group description
3180information in hex, and also prints the location of the superblock and
3181block group descriptor for those block groups that have them.
3182
3183Mke2fs now clears the ext2 superblock before it starts creating a
3184filesystem, so that the superblock magic number is only written if the
3185filesystem creation process successfully completes.
3186
3187The debugfs program's stat command now pretty-prints the blocks used
3188by an inode so that it's more compact and informative.
3189
3190The debugfs stats command now uses the same libe2p code (which is used
3191by dumpe2fs) to print the superblock header information. This is more
3192complete, and it avoids a bit of code duplication.
3193
3194Added a new debugfs command, set_super_value (ssv) which allows the
3195user to set arbitrary superblock fields.
3196
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003197Debugfs was extended to support inode numbers in hex (by prefixing
3198them with 0x), and so that modify_inode can set the inode generation
3199number. Also, there is now a new function command called logdump
3200which will dump an ext3 journal.
3201
3202Fixed a bug in debugfs so that quitting out of the pager doesn't kill
3203debugfs.
3204
3205Debugfs's dump command now stops immediately upon reporting a disk
3206read error. (Fixed a bug in ext2fs_file_read library routine which
3207caused debugfs not to stop.) (Debian bug #79163)
3208
3209On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
3210checked before /etc/mtab is used, since /proc/mounts is more likely to
3211be accurate.
3212
3213Added portability fixes for Solaris and Linux/ia64.
3214
3215Various manual pages were clarified and cleaned up. (Fixed debian
3216bugs #63442, #67446, and #87216)
3217
Theodore Ts'o5570a652000-08-21 01:23:39 +00003218
3219Programmer's notes:
3220-------------------
3221
3222The e2fsck message printer now supports %Iu and %Ig, which will print
3223out the inode's user and group owners, respectively.
3224
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003225E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
3226that no longer dependent on the system having the correct version of
3227the kernel header files.
3228
Theodore Ts'o5570a652000-08-21 01:23:39 +00003229Added a new function to libext2, ext2fs_find_block_device(), which
3230searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
3231device given its device number.
3232
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003233Added a new function to libext2, ext2fs_sync_device, which centralizes
3234all of the places which might try to use the BLKFLSBUF or FDFLUSH
3235ioctls (and usually failing to define them since the system header
3236files don't usually do this for us, and we're trying to avoid usage of
3237kernel include files now).
3238
Theodore Ts'o5570a652000-08-21 01:23:39 +00003239Added new utility programs in tests/progs: random_exercise and
3240hold_inode. They aren't built by default; they're useful for
3241exercising ext3 filesystem code.
3242
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003243Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
3244the filesystem close functions to only update the superblock, and to
3245not touch the block group descriptors. Needed by tune2fs when
3246modifying a mounted filesystem.
3247
3248Got rid of struct ext2fs_sb and replaced it with the standard struct
3249ext2_super_block from include/linux/ext2_fs.h. Note: this may break
3250source (but not binary) compatibility of some users of the ext2
3251library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00003252replace of struct ext2fs_sb with struct ext2_super_block, and include
3253the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003254
3255The ino_t type has been renamed ext2_ino_t to protect applications
3256that attempt to compile -D_FILE_OFFSET_BITS=64, since this
3257inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
3258unexpected ABI change.
3259
3260The Makefiles have been reworked so that "make check" can be run from
3261the top-level Makefile.
3262
3263Fix general gcc -Wall complaints and removed dead code.
3264
3265Remove use of NOARGS, because we assume everyone does ANSI C these
3266days.
3267
3268Added build-rpm script from sct.
3269
3270New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
3271to support e2image.
3272
3273New function ext2fs_flush_icache which must be called if the
3274application program modifies the inode table blocks without going
3275through ext2fs_write_inode() interface.
3276
3277New ext2fs_check_mount_point() function, which will return the mount
3278point of a device if mounted.
3279
3280The io_channel abstraction now has an optional interface,
3281io_channel_write_range, which allows specific byte ranges to be
3282written.
3283
3284The unix_io IO channel now supports write-through caching, so that
3285journal creation is more efficient.
3286
3287Added x86 assembly language routines to support byte swapping, to
3288reduce executable size.
3289
3290Fixed bug in the utility program subst so that it's possible to
3291replace a substitution variable with a zero-length string.
3292
3293Fixed numbering e2fsck pass1 problem numbers; an extra zero had
3294slipped into some of the problem number.

Theodore Ts'ob777e262000-07-27 01:39:23 +00003296E2fsprogs 1.19 (July 13, 2000)
3297==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00003298
3299Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00003300be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00003301
3302Add experimental support needed for the ext2 compression patches.
3303This requires compiling e2fsprogs with the --enable-compression flag
3304to the configure script.
3305
3306Added ext3 journalling support. E2fsck will run the journal (if
3307necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
3308installed as a symlink to e2fsck. Fsck has been taught about ext3,
3309and treats it the same as ext2 in terms of the progress bar logic.
3310Dumpe2fs will display the superblock journaling information if the
3311filesystem has a journal. The ext2 library will now permit opening an
3312ext3 filesystem with the recovery flag set. This is necessary for
3313on-line dump's to work correctly, but there may be issues with this
3314working well since ext3 is much less agressive about syncing blocks to
3315the filesystem, since they're safe on the journal.
3316
3317Tune2fs and e2fsck have been changed to allow the mount_count check to
3318be disabled by setting max_mount_count to -1. (This was already
3319supported by the kernel.)
3320
3321Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
3322are used for ext3 as well.
3323
3324Added internationalization support for e2fsprogs; must be enabled
3325by passing --enable-nls to configure.
3326
3327Always use the provided ext2fs header files to insulate ourselves from
3328kernel version changes. Which include files are used by e2fsprogs
3329have also been cleaned up to improve portability.
3330
3331Limit the number of times that e2fsck updates the progress bar so that
3332people who are booting using a 9600 baud console don't get swampped by
3333too many updates.
3334
3335Improved the loop detection algorithm in e2sck's pass #3 so that it is
3336much, much faster for large filesystems with a large number of
3337directories.
3338
3339The memory footprint for e2fsck is now slightly smaller than before.
3340
3341E2fsck now checks if special devices have a non-zero size, and offers
3342to clear the size field if it finds such an inode.
3343
3344E2fsck now checks if special devices have the append-only flag set,
3345and offers to clear the inode.
3346
3347E2fsck now properly handles some "should never fail" cases during a
3348bitmap copy in pass5.
3349
3350E2fsck now properly prints control characters in filenames as ^A .. ^Z.
3351
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003352E2fsck now calculates the correct location of the backup superblock in
3353the case of filesystem blocksizes > 1k.
3354
3355Fixed a bug in e2fsck's calculation of the number of inodes_per_block
3356which normally didn't cause problems under most filesystem parameters,
3357but could cause a valid superblock to be rejected in extreme cases.
3358Other checks for validating superblock values were made more
3359stringent.
3360
Theodore Ts'oab146762000-07-07 04:37:35 +00003361Added non-destructive write testing to the badblocks program, courtesy
3362of David Beattie. The badblocks also now has an option to input the
3363current set of bad blocks, so that known bad blocks are skipped to
3364speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00003365feature which causes badblocks to run until it has completed some
3366number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00003367
3368Badblocks now checks to see if the device is mounted and refuses to do
3369the tests involving writing to the device if it is mounted. Also,
3370badblocks now allows the number of blocks to be checked to be
3371defaulted to the size of the partition.
3372
3373Fixed a bug in fsck which didn't allow non-root users to be able to
3374check filesystems if there were any LABEL= or UUID= entries in
3375/etc/fstab.
3376
3377The Hurd doesn't support the filetype filesystem feature. The mke2fs
3378program now makes sure that for the Hurd, the filestype feature is
3379turned off. E2fsck will check to see if the filetype feature is
3380turned on for Hurd filesystems, and offer to turn off the feature.
3381
3382Mke2fs now has a safety check to make sure the number of blocks do not
3383exceed 32 bits even on a 64 bit platform.
3384
3385Really fixed a bug in fsck to allow "fsck -As" to run interactive
3386fsck's. (For those people who like to do interactive fsck's in the
3387/etc/rc scripts!?!)
3388
3389Debugfs has a few new features: the rdump command, which will do a
3390recursive dump of a directory and all of its contents, and the lcd
3391command which does a local chdir (much like the ftp command of the
3392same name). In addition, the debugfs program and the open_filesystem
3393command now takes three new options: -b and -s, which allows the
3394blocksize and superblock location to be specified, and the -c option
3395which is used in catastrophic situations where the block group
3396descriptors are corrupt. If the -c option is specified, debugfs will
3397skip trying to read in the block and inode bitmaps.
3398
3399Debufs's lsdel command was fixed to handle bad blocks in the inode
3400table.
3401
3402A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
34034 digit years.
3404
3405General improvements in error messages
3406
3407 - Mke2fs prints a sane error message if the partition size is zero
3408 (usually because the partition table wasn't reread by the
3409 kernel due to the partition being busy), instead of "invalid
3410 argument passed to ext2 library while initializing superblock".
3411
3412 - Fsck now prints more self-explanatory message if an invalid UUID=
3413 or LABEL= specification is passed to it.
3414
3415UUID library changed to use the LGPL.
3416
3417Fixed a bug in the UUID library where very rapid calls to the
3418time-based UUID generator could cause duplicate UUID's to be returned.
3419This was not a problem for e2fsprogs, but it could be a problem for
3420other users of the library.
3421
3422Make the UUID library more robust in the face of missing or an
3423improper /dev/urandom or /dev/random files.
3424
3425Added some random portability fixes for Solaris.
3426
3427Some minor man page updates.
3428
3429Fixed a memory leak in the ss library.
3430
3431
3432Programmer's notes:
3433-------------------
3434
3435We now try to use lseek64 and open64 from the LFS if possible.
3436
3437The 3rd parameter in e2p's print_flags is now a flags word, instead of
3438a boolean option.
3439
3440The mark and unmark bitmap functions now return the previous state of
3441the bit that was being changed, which is useful for some speed
3442optimizations.
3443
3444The following functions have been added to enhance the badblocks list
3445handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3446ext2fs_badblocks_equal.
3447
3448The ext2 header files now have the latest journalling fields to the
3449superblock.
3450
3451The ext2fs_mkdir function in libext2fs now properly backs out of error
3452conditions robustly.
3453
3454Cleaned up makefiles:
3455 - to cleanly compile with the -j flag.
3456 - so distclean removes all generated files.
3457 - so in case of an error while installing header files, the make aborts.
3458
3459Fix test_script so that it works correctly when compiling in the
3460source directory.
3461
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003462The random UUID generation routine has been made slightly better in
3463the case where /dev/random doesn't exist. (Use of randomly-based UUID
3464is still not recommended if /dev/random doesn't exist, however; it's
3465better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00003466
3467Clean up the build process so it's more friendly in case of missing
3468directories.
3469
3470The ext2fs header file can now be #include'd into C++ programs.
3471
3472The e2p.h header file is now installed.
3473
3474Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3475
3476
3477
Theodore Ts'o24ded091999-11-10 15:56:16 +00003478E2fsprogs 1.18 (November 10, 1999)
3479==================================
3480
3481Fix a core dumping bug in e2fsck if an imagic inode is present or
3482(more rarely) if the filesystem is badly corrupted enough that e2fsck
3483has to restart pass 1 processing. E2fsck now closes the filesystem
3484before freeing a large number of its data structures, so in the case
3485of future memory faults, at least the fixed filesystem will be fully
3486written out.
3487
3488If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3489imagic inode, it will offer to clear the imagic flag.
3490
3491E2fsck will now offer to clear the immutable flag on special files
3492(device/socket/fifos) when running it in non-preen mode.
3493
3494E2fsck will now set the filetype when creating /lost+found, and when
3495connected orphaned inodes to /lost+found.
3496
3497Debugfs's ncheck and icheck commands now handles the case where there
3498are bad blocks in the inode table without bombing out.
3499
3500The badblocks list processing code has been made more efficiently for
3501appending a large number of (ordered) badblocks to the badblocks list.
3502
3503Some minor man page updates.
3504
3505Fsck now allows interactive e2fsck's when using fsck -As (not a common
3506mode, but some people like to do this in boot scripts for silly reasons).
3507
3508Programmer's notes:
3509-------------------
3510
3511The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3512with the problem code convention.
3513
3514The badblocks list regression test program has been updated to work
3515with previously made API name changes.
3516
3517The ext2fs_free() command now uses the new badblocks API to avoid
3518using the compatibility layer.
3519
3520Added new regression test cases; the run_e2fsck test script now
3521supports the ability for a test case to run a prepratory command
3522before running e2fsck.
3523
Theodore Ts'o28e11941999-10-26 18:17:20 +00003524E2fsprogs 1.17 (October 26, 1999)
3525=================================
3526
3527Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3528infinite loop.
3529
3530Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3531thus potentially causing problems if a binary UUID contained a NULL
3532character.
3533
3534E2fsck now uses stricter checks for directory entries in pass 2:
3535zero-length filenames are not allowed; neither are 8 byte long
3536directory entries.
3537
3538The debugfs "dirty" command now clears the filesystem valid bit.
3539(Previously this just set the dirty-as-in-needs-writing-out-to-disk
3540bit in the in-core superblock image. The new functionality is more
3541what the user expects, and is more useful.)
3542
3543Added a debugging hook to test parallel fsck; if the environment
3544variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3545will be checked in parallel when they normally would not be.
3546
3547Programmer's notes:
3548-------------------
3549
3550Fixed some #ifdef's for compilation under the Hurd OS.
3551
3552Fixed minor W2K compatibility problems.
3553
3554Fixed some miscellaneous GCC warnings.
3555
3556
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00003557E2fsprogs 1.16 (October 22, 1999)
3558=================================
3559
3560Fixed a race condition bug in fsck; when printing a progress bar, if
3561checking multiple filesystems in parallel, it was possible for fsck to
3562send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3563handler, which would cause it to terminate with a signal 10.
3564
3565E2fsck now properly handles filesystems that have the
3566INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3567filesystem into using or not using FILETYPE feature.
3568
3569E2fsck now properly handles filesystems that have the IMAGIC feature
3570turned on (this is used on Linux AFS servers).
3571
3572The mke2fs program now creates filesystems that have the filetype and
3573sparse_superblock features enabled by default, unless it is run on a
3574pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3575so there is now a new flag -O which allows the user to specify with
3576which features she would like to create the filesystem; "mke2fs -O
3577none" will create a filesystsem compatible with 2.0 kernels.
3578
3579The tune2fs program now has a -O option which allows the user to set
3580and reset "safe" filesystem features. Currently, the only ones which
3581allows to be modified are the filetype and sparse_superblock features.
3582Note setting or clearing either feature will require running e2fsck on
3583the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3584requires that there is enough free space on the filesystem for the
3585extra superblocks which will be created by e2fsck.)
3586
3587Debugfs can now set and print filesystem features in the superblock
3588using the "features" command. Dumpe2fs will print out the complete
3589set of features when listing the superblock.
3590
3591Dumpe2fs has new options -f (force) and -h (header-only).
3592
3593Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3594message to come up. This could happen when decrementing or
3595incrementing a link count could result in an overflow.
3596
3597Fixed a bug in e2fsck where the block count on the lost+found
3598directory would not be properly incremented when the directory was
3599expanded to the point where an indirect block needed to be allocated.
3600
3601E2fsck now makes some additional sanity checks on the superblock to
3602avoid crashing or giving a memory allocation error if some of the
3603values in the superblock are unresonable (but the superblock otherwise
3604looks valid).
3605
3606Fixed a bug in e2fsck where a very badly corrupted filesystem might
3607require two passes to completely fix the filesystem. This happened if
3608an inode claimed blocks that was part of the filesystem metadata
3609(typically, when garbage was written into an inode table or indirect
3610block, since this kind of filesystem corruption normally doesn't
3611happen otherwise).
3612
3613On the Alpha, glibc declares st_flags although it isn't actually used;
3614the configure script was improved to detect this case so that
3615e2fsprogs can avoid using the non-functional stat field.
3616
3617The manual pages were updated to use a more consistent formatting
3618style consistent with standard Unix man pages. Mke2fs's man page
3619added documentation for a few previously undocumented options.
3620
3621Fixed minor display bugs in tune2fs and mke2fs.
3622
3623Programmer's notes:
3624-------------------
3625
3626Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
3627
3628Added features to parse and print feature strings into the e2p library.
3629(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
3630
3631ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
3632whose directory entries contain proper filetype information if the
3633filesystem supports it.
3634
3635ext2fs_link() now uses the low 3 bits of its flags parameter to pass
3636the directory entry filetype information. This is used to set the
3637directory entry filetype information if the filesystem supports it.
3638
3639Fixed a bug in ext2fs_expand_dir() where the block count in a
3640directory's inode would not be properly incremented when the directory
3641was expanded to the point where an indirect block needed to be
3642allocated.
3643
3644
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003645E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003646==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003647
3648Add configuration checks so that e2fsprogs will compile cleanly on
3649Linux 2.3 kernels that have renamed i_version to i_generation.
3650
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003651E2fsck now prints a progress/completion bar (and not just a simple
3652spinner) if the -C0 option is requested or if it receives a SIGUSR1
3653signal. Fsck will automatically manage the (potentially muliple)
3654e2fsck processes to print completion bars if it is given a -C option,
3655with the right thing happening if multiple filesystems are being
3656checked in parallel.
3657
3658Mke2fs now has better automatic hueristics to determine the filesystem
3659parameters to be used for a particular filesystem. Added a new option
3660-T which allows the user to specify how the filesystem is to be used,
3661which helps mke2fs do a better job selecting the filesystem parameters.
3662
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003663Mke2fs now creates revision 1 filesystems by default, and with the
3664sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00003665not understood by Linux 2.0 kernels, so they will only allow read-only
3666mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003667
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003668Fix bug where if /dev/null couldn't be opened (should never happen),
3669e2fsck would hang in a tight loop.
3670
3671Make e2fsck handle the case where /lost+found isn't a directory.
3672
3673E2fsck now uses mallinfo if it exists to get accurate statistics about
3674its memory usage.
3675
3676Fix bug in e2fsck where it wouldn't check to see if a disconnected
3677inode had any problems before connecting it to /lost+found.
3678
3679Add check to e2fsck so it makes sure that total number of inodes in
3680the filesystem is a sane number.
3681
3682Fix fencepost error when clearing an the end of the block bitmap which
3683caused the last block in the bitmap not to get cleared.
3684
3685Cleaned up a number of messages in e2fsck:
3686 * The message "Group's #'s copy of the group descriptor..."
3687 was fixed so that the correct number would be displayed.
3688 * Added missing space in the "disk write-protected" error messsage
3689 * Cleaned up the error message printed when a non-interactive
3690 e2fsck needs to abort a check because the filesystem
3691 appears to be mounted.
3692
3693Added a new command-line utility, uuidgen, which will create and print
3694a UUID.
3695
3696Make debugfs's icheck command more robust by checking to make sure an
3697inode has valid blocks before interarting over the inode's blocks.
3698
3699UUID generation now uses a random-based scheme whenever possible to
3700prevent potential privacy problems.
3701
3702Man pages for all of the UUID functions in the lirbary were added.
3703
3704Fixed bug in fsck so it won't coredump if a filesystem not in
3705/etc/fstab is given to it.
3706
3707Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
3708that most of the other mount utilities understands.
3709
3710Mke2fs will make a filesystem even if it appears mounted if the force
3711option is given.
3712
3713Dumpe2fs has new command-line options which allow a filesystem expert
3714to specify the superblock and blocksize when opening a filesystem.
3715This is mainly useful when examining the remains of a toasted
3716filesystem.
3717
3718The badblocks program has been updated to display correctly on disks
3719with large block numbers.
3720
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003721The badblocks program no longer gives spurious errors when errors
3722occur on non-block boundaries, which is common if the blocksize is
3723larger than 1k.
3724
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003725Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
3726MKE2FS_SYNC environment variable is set. This is to work around a VM
3727bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003728to trigger it even using a 2.2 kernel, but hopefully it will not be
3729needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003730
3731Fixed miscellaneous documentation and man pages.
3732
3733Programmer's notes:
3734-------------------
3735
3736Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
3737in e2fsck's pass1.c really should have been static.
3738
3739The return value of the uuid_compare() function was changed to make it
3740match with the convetions used by strcmp, memcmp, and Paul Leach's
3741UUID sample document.
3742
3743The "make depend" process has now been made more automated; it now
3744automatically word-wraps the dependencies, and only replaces source
3745Makefile.in if there has been a change in the dependencies. Also, a
3746top-level "make depend" now recurses through all the subdirectories
3747automatically.
3748
3749The Makefile in .../util has been changed so that subst is built using
3750the native C compiler during a cross-compilation, since the subst
3751program is only used during the build process. Also add an explicit
3752rule to build util/subst by cd'ing to the correct directory and
3753running Makefile.
3754
3755The man directories are defined in terms mandir, so that the configure
3756script can override the location of the manual pages.
3757
3758The config files have been updated to recognize new machine types for
3759both the i386 and alpha families.
3760
3761Fsck has been modified so that it will accurately create an
3762fsck_instance even when the noexecute flag is set. This allows for
3763accurate debugging of the fsck pass structure. Also, when the verbose
3764flag is given twice, fsck will print debugging information about when
3765fsck is waiting for jobs to finish.
3766
3767
Theodore Ts'o14790ed1999-01-12 23:32:52 +00003768E2fsprogs 1.14 (January 9, 1999)
3769================================
3770
3771Fix the fstab parsing code so that it can handle blank lines and
3772comment characters. Also, missing pass numbers need to be treated as
3773zero.
3774
3775Fixed a bug in e2fsck where under some circumstances (when e2fsck
3776needs to restart processing after fixing an egregious inconsistency)
3777it would try to access already freed memory.
3778
3779E2fsck now prints non-printable characters in directory entries and
3780pathnames using '^' and 'M-' notation.
3781
3782Fixed chattr so that it will ignore symbolic links when doing
3783recursive descent traversals. For both chattr and lsattr, no longer
3784print the version string unless the -V option is given.
3785
3786Allow the system administrator to directly specify the number of
3787inodes desired in the filesystem, for some special cases where this is
3788necessary.
3789
3790Fix portability problems so that e2fsprogs can be compiled under Linux
37911.2 systems and Solaris systems.
3792
3793Update the config.guess file with a more recent version that will
3794identify newer Linux platforms.
3795
3796Programmer's notes
3797------------------
3798
3799Ext2fs_read_inode and ext2fs_write_inode will now return an error if
3800an inode number of zero is passed to them.
3801
Theodore Ts'o556ad131998-12-19 08:10:58 +00003802E2fsprogs 1.13 (December 15, 1998)
3803==================================
3804
3805Fixed a bug in debugfs where an error messages weren't getting printed
3806when the ext2 library routines to read inodes returned errors in the
3807stat, cmri and rm commands.
3808
3809Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
3810provided, it won't create an inode table smaller than the minimum
3811number of inodes required for a proper ext2 filesystem.
3812
3813Fsck now parses the /etc/fstab file directly (instead of using
3814getmntent()), so that it can distinguish between a missing pass number
3815field and pass number field of zero. This caused problems for
3816diskless workstations where all of the filesystems in /etc/fstab have
3817an explicit pass number of zero, and fsck could not distinguish this
3818from a /etc/fstab file with missing pass numbers.
3819
3820E2fsck will create a /lost+found directory if there isn't one in the
3821filesystem, since it's safer to create the lost+found directory before
3822it's needed.
3823
3824Fixed e2fsck so that it would detect bogus immutable inodes which
3825happen to be sockets and FIFO files, and offer to clear them.
3826
3827If a filesystem has multiple reasons why it needs to be checked, and
3828one of the reasons is that it is uncleanly mounted, e2fsck will print
3829that as the reason why the filesystem is being checked.
3830
3831Cleaned up the output routines of mke2fs so that it doesn't overflow
3832an 80 column display when formating really big filesystems.
3833
3834Added a sanity check to e2fsck to make sure that file descriptors 0,
38351, 2 are open before opening the hard disk. This avoids a problem
3836where a broken program might exec e2fsck with those file descriptors
3837closed, which would cause disastrous results if the kernel returns a
3838file descriptor for the block device which is also used by FILE *
3839stdout.
3840
3841Fixed up the e2fsck progress reporting functions so that the values
3842reliably reach 100% at the completion of all of the e2fsck passes.
3843
3844Fixed minor documentation bugs in man pages and usage messages.
3845
3846Programmer's notes:
3847-------------------
3848
3849Fixed a number of lint warnings in the ext2fs library and potential
3850portability problems from other OS's header files that might define
3851CPP macros for names like "max" and "min".
3852
3853ext2fs_badblocks_list_add() has been made more efficient when it needs
3854to grow the bad blocks list.
3855
3856Fixed a bug in e2fsck which caused it to dereference a freed pointer
3857just before exiting.
3858
3859Fixed the substition process for generating the mk_cmds and compile_et
3860scripts so that they will work outside of the build tree.
3861
3862Add sanity check to e2fsck so that if an internal routine
3863(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
3864and causing a core dump. This should never happen, but...
3865
Theodore Ts'oa5696711998-07-09 05:38:07 +00003866E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00003867==================================
3868
3869E2fsprogs now works with glibc (at least with the version shipped wtih
3870RedHat 5.0). The ext2fs_llseek() function should now work even with
3871i386 ELF shared libraries and if llseek() is not present. We also
3872explicitly do a configure test to see if (a) llseek is in libc, and
3873(b) if llseek is declared in the system header files. (See standard
3874complaints about libc developers don't understand the concept of
3875compatibility with previous versions of libc.)
3876
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003877The ext2fs library now writes out the block group number in each of
3878the superblock copies. This makes it easier to automatically
3879determine the starting block group of the filesystem when the block
3880group information is trashed.
3881
3882Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00003883which means that e2fsprogs will ignore the high 8 bits of the
3884directory entry's name_len field, so that it can be used for other
3885purposes.
3886
3887Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
3888E2fsprogs will now support filesystems with 64-bit sized files.
3889
3890Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
3891
Theodore Ts'o21d53851998-02-21 03:14:50 +00003892Added new program "e2label", contributed by Andries Brouwer. E2label
3893provides an easy-to-use interface to modify the filesystem label.
3894
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00003895Fixed bug so that lsattr -v works instead of producing a core dump.
3896
Theodore Ts'o21d53851998-02-21 03:14:50 +00003897Fixed a minor bug in mke2fs so that all groups with bad superblock
3898backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00003899
3900Mke2fs will check the size of the device, and if the user specifies a
3901filesystem size larger than the apparent size of the device it will
3902print a warning message and ask if the user wants to proceed.
3903
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003904E2fsck has a new option -C, which sends completion information to the
3905specified file descriptor. For the most part, this is intended for
3906programs to use, although -C 0 will print a spinning character to the
3907stdout device, which may be useful for users who want to see something
3908happening while e2fsck goes about its business.
3909
Theodore Ts'o21d53851998-02-21 03:14:50 +00003910Fixed a bug in e2fsck which could cause a core dump when it needs to
3911expand the /lost+found directory, and sometimes the bitmaps haven't
3912been merged in. Also fixed a related bug where ext2fs_write_dir_block
3913was used to write out a non-directory block. (Which would be bad on a
3914non-Intel platform with byte swapping going on.)
3915
3916Fixed bug in e2fsck where it would print a "programming error" message
3917instead of correctly identifying where a bad block was in used when
3918the bad block was in a non-primary superblock or block group
3919descriptor. Also fixed a related bug when sparse superblocks are in
3920use and there is a bad block where a superblock or block group
3921descriptor would have been in a group that doesn't include a
3922superblock.
3923
3924Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
3925the block group descriptor table is corrupt, it was possible to try to
3926allocate a huge array, fail, and then abort e2fsck.
3927ext2fs_get_num_dirs() now sanity checks the block group descriptor,
3928and subsitutes reasonable values if the descriptors are obviously bogus.
3929
3930If e2fsck finds a device file which has the immutable flag set and the
3931i_blocks beyond the normal device number are non-zero, e2fsck will
3932offer to remove it, since it's probably caused by garbage in the inode
3933table.
3934
3935When opening a filesystem, e2fsck specially checks for the EROFS error
3936code, and prints a specific error message to the user which is more
3937user friendly.
3938
3939If the filesystem revision is too high, change the e2fsck to print
3940that this is either because e2fsck is out of date, or because the
3941superblock is corrupt.
3942
3943E2fsck now checks for directories that have duplicate '.' and '..'
3944entries, and fixes this corruption.
3945
3946E2fsck no longer forces a sync of the filesystem (with attendant sleep
3947calls) at all times. The ext2fs_flush() function now performs a sync
3948only if it needed to write data blocks to disk.
3949
3950Fixed a minor bug in e2fsck's pass1b's file cloning function, where
3951certain errors would not be properly reported.
3952
3953Updated and expanded a few points in the man pages which users
3954complained wheren't explicit enough.
3955
3956Added special case byte-swapping code if compiling on the PowerPC, to
3957accomodate the strange big-endian variant of the ext2 filesystem that
3958was previously used on the PowerPC port.
3959
3960
3961Programmer's notes:
3962-------------------
3963
3964Removed C++ keywords from the ext2fs libraries so that it could be
3965compiled with C++.
3966
3967E2fsck's internal organization has now been massively reorganized so
3968that pass*.c don't have any printf statements. Instead, all problems
3969are reported through the fix_problem() abstraction interface. E2fsck
3970has also been revamped so that it can be called as a library from a
3971application.
3972
3973Added new fileio primitives in libext2fs for reading and writing
3974files on an unmounted ext2 filesystem. This interface is now used by
3975debugfs.
3976
3977Added a new libext2fs function for mapping logical block numbers of
3978a file to a physical block number.
3979
3980Added a new libext2fs function, ext2fs_alloc_block(), which allocates
3981a block, zeros it, and updates the filesystem accounting records
3982appropriately.
3983
3984Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
3985sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
3986
3987The libext2fs functions now use a set of memory allocation wrapper
3988functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
3989instead of malloc, free, and resize. This makes it easier for us to
3990be ported to strange environments where malloc, et. al. aren't
3991necessarily available.
3992
3993Change the libext2fs fucntion to return ext2-specific error codes
3994(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
3995and depending on the existence of system error codes (such as EEXIST
3996and ENOENT).
3997
3998Renamed io.h to ext2_io.h to avoid collision with other OS's header
3999files.
4000
4001Add protection against ext2_io.h and ext2fs.h being included multiple
4002times.
4003
4004The types used for memory lengths, etc. have been made more portable.
4005In generla, the code has been made 16-bit safe. Added Mark
4006Habersack's contributed DOS disk i/o routines.
4007
4008Miscellaneous portability fixes, including not depending on char's
4009being signed.
4010
4011The io_channel structure has a new element, app_data, which is
4012initialized by the ext2fs routines to contain a copy of the filesystem
4013handle.
4014
4015ext2fs_check_directory()'s callback function may now return the error
4016EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
4017really do the checking, despite the presence of the callback function.
4018
4019
Theodore Ts'obc210071997-06-17 05:41:36 +00004020E2fsprosg 1.11 (June 17, 1997)
4021==============================
4022
4023Fixed e2fsck to detect (previously ignored) conflicts between the
4024superblock or block group descriptors and block bitmaps, inode
4025bitmaps, and inode tables.
4026
4027Fixed bug in e2fsck so that when the message printed out when a block
4028or inode bitmap conflicts with other data, it has the correct group
4029number.
4030
4031Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
4032to badblocks. This meant that not all of the filesystem was being
4033tested for bad blocks!
4034
4035Fixed an array boundary overrun case which cropped up in
4036ext2fs_badblocks_list_test when a user tried running "mke2fs -c
4037-b 4096".
4038
4039Adjusted the number of columns printed by mke2fs when displaying the
4040superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00004041really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00004042
4043Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
4044dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
4045fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
4046
4047Programmer's notes:
4048-------------------
4049
4050Fixed install rule in lib/ss so that ss_err.h is actually getting
4051installed.
4052
4053Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
4054bassed back to the caller.
4055
4056Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
4057setting the current inode number (which meant this function wasn't
4058working at all).
4059
4060Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
4061blocks in the bitmap when increasing the size of the bitmap.
4062
4063Changed the initial number of blocks allocated by ext2fs_init_dblist()
4064to be more realistic.
4065
4066Added a new function ext2fs_allocate_group_table, which sets up the
4067group descriptor information (and allocates inode and block bitmaps,
4068and inode tables for a particular group). The function was created by
4069factoring out code form ext2fs_allocate_tables().
4070
4071Added a new function ext2fs_move_blocks which takes a bitmap of the
4072blocks to be moved, and moves them to another location on the
4073boardboard.
4074
4075Make the unix_io channel's io_channel_flush implementation calls sync()
4076to to flush the kernel buffers to disk.
4077
4078Added a new function ext2fs_dblist_count returns the number of
4079directory blocks in dblist.
4080
4081
Theodore Ts'oae851481997-04-29 18:13:24 +00004082E2fsprogs 1.10 (April 24, 1997)
4083===============================
4084
4085Mke2fs once again defaults to creating revision #0 filesystems, since
4086people were complaining about breaking compatibility with 1.2 kernels.
4087Warning messages were added to the mke2fs and tune2fs man pages that
4088the sparse superblock option isn't supported by most kernels yet (1.2
4089and 2.0 both don't support parse superblocks.)
4090
4091Added new flag to mke2fs, -R <raid options>, which allows the user to
4092tell mke2fs about the RAID configuration of the filesystem. Currently
4093the only supported raid option is "stride" which specifies the width
4094of the RAID stripe.
4095
4096Fixed bug in e2fsck where pass1b would bomb out if there were any
4097blocks marked bad in the inode table.
4098
4099Fixed rare bug in mke2fs where if the user had a very unlucky number
4100of blocks in a filesystem (probability less than .002) the resulting
4101filesystem would be corrupt in the last block group.
4102
4103Fixed bug where if e2fsck tried to allocate a block to fix a
4104filesystem corruption problem and the filesystem had no free blocks,
4105ext2fs_new_block() would loop forever.
4106
4107The configure script now checks explicitly to see if "-static" works,
4108since that can't be assumed to be true --- RedHat doesn't install
4109libc-static by default.
4110
4111Fixed bug in libext2's block iterator functions where under some
4112cirmcustances, file with holes would cause the bcount parameter to the
4113callback function to be incorrect. This bug didn't affect any of
4114e2fsprogs programs, but it was discovered by Paul Mackerras, the
4115author of the PPC boot loader.
4116
4117Removed use of static variables to store the inode cache in libext2fs.
4118This caused problems if more than one filesystem was accessed via
4119libext2fs (static variables in libraries are generally a bad idea).
4120Again, this didn't affect e2fsprogs programs, but it was discovered by
4121Paul Mackerras.
4122
4123Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
4124will compile cleanly with 1.2.13 kernels (even with a.out shared
4125libraries!)
4126
4127Programmer's notes:
4128-------------------
4129
4130Added new functions to duplicate an ext2 filesystem handle, and its
4131associated substructure. New functions: ext2fs_dup_handle(),
4132ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
4133Other structures, such as the io_channel and the inode_cache, now have
4134a ref count so that they only get freed when they are no longer used
4135by any filesystem handle. (These functions were added as part of the
4136development effort for an ext2 resizer).
4137
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00004138E2fsprogs 1.09 (April 14, 1997)
4139===============================
4140
4141Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
4142accidentally introduced in the 1.08 release. The overhead calculation
4143was accidentally removed, which caused ext2fs_initialize() to not
4144notice when the filesystem size needed to be adjusted down because
4145there wasn't enough space in the last block group.
4146
4147Fixed bug in version parsing library routine; it was always parsing
4148the library version string, instead of using the passed-in string.
4149
4150Clarified chattr man page.
4151
Theodore Ts'o24757fa1997-04-29 17:39:27 +00004152E2fsprogs 1.08 (April 10, 1997)
4153===============================
4154
4155E2fsck 1.07 was very slow when checking very large filesystems with a
4156lot of files that had hard links (i.e., news spools). This was fixed
4157by seriously revamping the icount abstraction. Added a formal test
4158suite for the icount abstraction.
4159
4160Debugfs now has a "-l" option to the "ls" command, which lists the
4161inode number, permissions, owner, group, size, and name of the files
4162in the directory.
4163
4164Fix a bug in e2fsck where when a directory had its blocks moved to
4165another location during the pass 1b processing, the directory block
4166list wasn't updated, so pass 2 wouldn't check (and correct) the
4167correct directory block.
4168
4169E2fsck will now treat inodes which contain blocks which are claimed by
4170the filesystem metadata by treating them as multiply claimed blocks.
4171This way, the data in those blocks can be copied to a new block during
4172the pass 1b--1d processing.
4173
4174E2fsck will attempt to determine the correct superblock number and
4175display it in the diagnostic and warning messages if possible.
4176
4177Add support for a new (incompatible) feature, "sparse_super". This
4178feature reduces the number of blocks which contain copies of backup
4179superblocks and block group descriptors. (It is only an incompatible
4180feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
4181support a new -s option; e2fsck will recognize filesystems built with
4182this feature turned on.
4183
4184E2fsck now checks the library to make sure is the correct version,
4185using new library functions. (This helps to diagnose incorrectly
4186installed e2fsprogs distributions.)
4187
4188Dumpe2fs now prints more information; its now prints the the
4189filesystem revision number, the filesystem sparse_super feature (if
4190present), the block ranges for each block group, and the offset from
4191the beginning of the block group.
4192
4193Mke2fs now distributes the inode and block bitmap blok so that the
4194won't be concentrated in one or two disks in RAID/striping setups.
4195Also, if the user chooses a 2k or 4k block group, mke2fs will try to
4196choose the largest blocks per group that be chosen. (For 2k blocks,
4197you can have up to 16384 blocks/group; for 4k blocks, you can have up
4198to 32768 blocks/group.) Previously mke2fs would not allow
4199specification of more than 8192 blocks per group, even if you were
4200using a 2k or 4k block group.
4201
4202Programmer's notes:
4203-------------------
4204
4205Added a new function ext2fs_create_icount2() which takes a "hint"
4206argument. This hint argument presets the icount array with the list
4207of inodes which actually need to be in the icount array. This really
4208helps to speed up e2fsck.
4209
4210Added a new function ext2fs_icount_validate() which checks the rep
4211invariant for the icount structure. This is used mostly for testing.
4212
4213The error mesasage given when a bad inode number is passed to
4214test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
4215EXT2FS_UNMARK_ERROR).
4216
4217Added a new function ext2fs_set_dir_block which sets the block of a
4218dblist entry, given the directory inode and blockcnt.
4219
4220Added a new function ext2fs_get_library_version() which returns the
4221current library version, and ext2fs_parse_version_string() which
4222returns a version number based on a e2fsprogs version string.
4223
4224The icount functions will return EINVAL if the passed in inode number
4225is out of bounds.

Theodore Ts'o21c84b71997-04-29 16:15:03 +00004227E2fsprogs 1.07 (March 9, 1997)
4228==============================
4229
4230E2fsck is now uses much less memory when checking really large
4231filesystems (or rather, filesystems with a large number of inodes).
4232Previously a filesystem with 1 million inodes required 4 megabytes of
4233memory to store inode count statistics; that storage requirement has
4234now been reduced to roughly half a megabyte.
4235
4236E2fsck can now properly deal with bad blocks appearing inside the
4237inode table. Instead of trying to relocate the inode table (which
4238often failed because there wasn't enough space), the inodes in the bad
4239block are marked as in use.
4240
4241E2fsck will automatically try to use the backup superblocks if the
4242primary superblocks have a bad magic number or have missing meta-data
4243blocks (or meta-data blocks which are out of range).
4244
4245E2fsck's pass 3 has been made more efficient; most noticeable on
4246filesystems with a very large number of directories.
4247
4248Completely revamped e2fsck's system of printing problem reports. It
4249is now table driven, to make them more easily customizeable and
4250extendable. Error messages which can be printed out during preen mode
4251are now one line long.
4252
4253Fixed e2fsck's filesystem swapping code so that it won't try to swap
4254fast symbolic links or deleted files.
4255
4256Fixed e2fsck core dumping when fixing a filesystem which has no
4257directories (not even a root directory).
4258
4259Added a check to e2fsck to make sure that the length of every
4260directory entry is a multiple of 4 (since the kernel complains if it
4261isn't).
4262
4263Added a check to e2fsck to make sure that a directory entry isn't a
4264link to the root directory, since that isn't allowed.
4265
4266Added a check to e2fsk to now make sure the '.' and '..' directory
4267entries are null terminated, since the 2.0 kernel requires it.
4268
4269Added check to write_bitmaps() to make sure the superblock doesn't get
4270trashed if the inode or block bitmap is marked as being block zero.
4271
4272Added checking of the new feature set fields in the superblock, to
4273avoid dealing with new filesystem features that this package wasn't
4274set up to handle.
4275
4276Fixed a fencepost error in ext2fs_new_block() which would occasionally
4277try to allocate a block beyond the end of a filesystem.
4278
4279When the UUID library picks a random IEEE 802 address (because it
4280can't find one from a network card), it sets the multicast bit, to
4281avoid conflicting with a legitimate IEEE 802 address.
4282
4283Mke2fs now sets the root directory's owner to be the real uid of the
4284user running mke2fs. If the real uid is non-zero, it also sets
4285the group ownership of the root directory to be the real group-id of
4286the user running mke2fs.
4287
4288Mke2fs now has more intelligent error checking when it is given a
4289non-existent device.
4290
4291When badblocks is given the -vv option, it now updates the block that
4292it is currently testing on every block.
4293
4294Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
4295currently correctly if PATH wasn't already set.
4296
4297Shared libraries now built with dependencies. This allows the shared
4298library files to be used with dlopen(); it also makes the transition
4299to libc 6 easier, since ld.so can tell which libc a particular shared
4300library expects to use.
4301
4302Programmer's notes:
4303-------------------
4304
4305Added new abstraction (defined in dblist.c) for maintaining a list of
4306blocks which belongs to directories. This is used in e2fsck and other
4307programs which need to iterate over all directories.
4308
4309Added new functions which test to see if a contiguous range of blocks
4310(or inodes) are available. (ext2fs_*_bitmap_range).
4311
4312Added new function (ext2_inode_has_valid_blocks) which returns true if
4313an inode has valid blocks. (moved from e2fsck code).
4314
4315Added new function (ext2fs_allocate_tables) which allocates the
4316meta-data blocks as part of initializing a filesystem. (moved from
4317mke2fs code).
4318
4319Added a new I/O manager for testing purposes. It will either allow a
4320program to intercept I/O requests, or print debugging messages to
4321trace the activity of a program using the I/O manager.
4322
4323The badblocks_list functions now store the bad blocks in a sorted
4324order, and use a binary search to speed up badblocks_list_test.
4325
4326The inode scan function ext2fs_get_next_inode() may now return a soft
4327error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
4328those cases where part of an inode table is missing or there is a bad
4329block in the inode table.
4330
4331Added a new function (ext2fs_block_iterate2) which adds new arguments to
4332the callback function to return a pointer (block and offset) to the
4333reference of the block.
4334
4335Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
4336application to jump to a particular block group while doing an inode
4337scan.
4338
4339The badblocks list functions were renamed from badblocks_* to
4340ext2fs_badblocks_*. Backwards compatibility functions are available
4341for now, but programs should be modified to use the new interface.
4342
4343Some of the library functions were reorganized into separate files to
4344reduce the size of some programs which statically link against the
4345ext2 library.
4346
4347Put in some miscellaneous fixes for the Alpha platform.
4348
Theodore Ts'o5c576471997-04-29 15:29:49 +00004349
4350E2fsprogs 1.06 (October 7, 1996)
4351================================
4352
4353Fixed serious bug in e2fsck: if the block descriptors are bad, don't
4354smash the backup copies in ext2fs_close(). (The problem was that when
4355e2fsck -p discovered the problem, while it was closing the filesystem
4356and exiting, it was also blowing away the backup superblocks on the
4357disk, which was less than friendly.) We now make it the case that we
4358only write out the backup superblock and the back block descriptors if
4359the filesystem is completely free from problems.
4360
4361Fixed a bug in block_interate in the lib/ext2fs library which caused
4362e2fsck to fail on GNU Hurd-created filesystems.
4363
4364Add support for Linux/FT's bootloader, which actually uses
4365EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
4366to clear the inode.
4367
4368Add support for the "A" (no atime update) attribute. (Note: this
4369attribute is not yet in production kernels.)
4370
4371The test suite is not automatically run when doing a "make all" from
4372the top level directory. Users should manually run "make check" if
4373they wish to run the test suite.
4374
4375Upon a preenhalt(), make the printed message more explicit that
4376running e2fsck "MANAULLY" means without the -p or -a options.
4377
4378In e2fsck, if a disconnected inode is zero-length, offer to clear it
4379instead of offering to connect it to lost+found.
4380
4381In e2fsck, if a filesystem was just unmounted uncleanly, and needs
4382e2fsck to be run over it, change e2fsck to explicitly display this
4383fact.
4384
4385For dumpe2fs and e2fsck, cause the -V option to print out which
4386version of the ext2fs library is actually getting used. (This will
4387help detect mismatches of using a 1.06 utility with a 1.05 library,
4388etc.)
4389
4390Programmers' notes:
4391-------------------
4392
4393EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
4394the naming convention.
4395
4396In ext2fs_initialize(), make sure the description for the inode bitmap
4397is correctly initialize.
4398
4399Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4400
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00004401E2fsprogs 1.05 (September 7, 1996)
4402==================================
4403
4404Add support for new fields in the ext2 superblock --- volume name,
4405volume UUID, and last mounted field. Dumpe2fs displays these fields,
4406tune2fs and mke2fs allows you to set them. E2fsck will automatically
4407generate a UUID for those volumes that don't have them.
4408
4409Put in support for e2fsck to recognize HURD specific ext2 features ---
4410most notably, the translator block. The e2fsprogs tools will now use
4411the creator_os field in the superblock to correctly handle different
4412OS-specific variants of the ext2 filesystem.
4413
4414E2fsck now fixes inodes which have a the deletion time set, but which
4415have a non-zero i_link_count field by offering to clear the deletion
4416time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4417ext2 kernel behavior) and offered to unlink the file.
4418
4419If e2fsck sets the clean bit, but nothing else, set the exit code
4420FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4421set the filesystem valid bit when it was previously cleared. :-) This
4422was needed to make the HURD fsck driver happy.
4423
4424If the user refuses to attach an unattached inode, e2fsck will no
4425longer set the inode's link count. Otherwise, the inode would end up
4426getting marked as unused, which might cause loss of data later.
4427
4428Make the message issued by e2fsck when the superblock is corrupt less
4429confusing for users. It now mentions that another reason for the
4430"corrupt superblock" message might be that the partition might not be
4431an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4432
4433Make the libext2 library more robuest so that e2fsck won't coredump on
4434an illegal superblock where the blocksize is zero. (f_crashdisk is
4435the test case).
4436
4437By default, create filesystems where the default checkinterval is 6
4438months (180 days). Linux servers can be robust enough that 20 reboots
4439can be a long, long time.
4440
4441Added configure flag --enable-old-bitops, which forces the bitops to
4442use the old (native) bitmask operations. By default on the sparc
4443platform, the standard ext2 bit ordering is now used.
4444
4445Added a new feature to e2fsck to byte-swap filesystems; this can be
4446used to convert old m68k filesystems to use the standard byte-order
4447storage for the superblock, inodes, and directory blocks. This
4448function is invoked by using the '-s' option to e2fsck.
4449
4450Debugfs's "dump" command has been enhanced so that it writes out the
4451exact size of the file so that the nulls at the end of the file are
4452eliminated. The command also accept a new "-p" option which will
4453attempt preserve to preserve the ownernship, permissions, and
4454file modification/access times.
4455
4456Debugfs has two new options, -f and -R. The -R option allows the user
4457to execute a single debugfs command from the command line. The -f
4458option allows the user to specify a "command file" containing debugfs
4459commands which will get executed.
4460
4461Dumpe2fs now pretty prints the check interval, instead of just
4462printing the check interval as a number of seconds.
4463
4464Fix bugs in debugfs: the params command when no filesystem is opened
4465no longer causes a core dump. It is now possible to unlink a file
4466when a pathame containing a '/' is specified.
4467
4468Tune2fs has a new -C option which sets the number of times the
4469filesystem has been mounted.
4470
4471Fix the chattr '-v' option so that it actually works. Chattr was
4472being buggy about the -v option parsing.
4473
4474Programmers' notes:
4475-------------------
4476
4477The directory lib/uuid contains a set of library routines to generate
4478DCE compatible UUIDs.
4479
4480Extended ext2fs_namei() to handle symbolic links. Added new function
4481ext2fs_nami_follow() which will follow last symbolic link in the case
4482where the pathname points to a sym link.
4483
4484The ext2fs_block_iterate function will now return the HURD translator
4485block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4486iterator to return data blocks only. The ext2fs.h file now defines
4487constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4488BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4489count field of the iterator callback function.
4490
4491The test script driver now takes an optional second argument, which is
4492the test case to be run. This allows you to run a test case without
4493needing to run the entire test suite.
4494
4495On Linux ELF systems, install the .so files in the correct places
4496(/usr/lib). The .so files must be stored in the same directory as the
4497.a files.
4498
4499Fixed miscellaneous HURD compilation issues with header file being
4500included in the right order.
4501
4502Fixed debugfs so that it resets optind to zero, not one, since setting
4503optind to zero is more correct.
4504
4505
Theodore Ts'oa4d09611997-04-29 14:28:00 +00004506E2fsprogs 1.04 (May 16, 1996)
4507=============================
4508
4509First "official" (1.03 was a limited release only) to support building
4510e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4511kernels).
4512
4513This package includes a RPM specs file, that it can be built using the
4514RedHat Package Manager.
4515
4516E2fsck now prints a hint that if there are lots of incorrectly located
4517inode bitmaps, block bitmaps, and inode table blocks, the user might
4518want to try using e2fsck -b 8193 first, to see if that fares any
4519better.
4520
4521For ext2 filesystem written with the hurd, debugfs will now print out
4522the translator field when printing an inode structure.
4523
4524Lots of miscellaneous linking/installation cleanups:
4525
4526 Libraries are now linked using a relative pathname, instead of
4527 relying on -L working correct. It doesn't, in many cases, including
4528 current versions of GNU ld. This guarantees that the build tree is
4529 linking with the right libraries, instead of the ones installed in
4530 /usr/lib.
4531
4532 Header files, man pages, and the et/ss shell scripts are now
4533 generated using a custom substitution script, instead of relying on
4534 the configure script. This prevents needless recompilation of
4535 files; in addition, the custom substitution script is much faster.
4536
4537 e2fsck may now be linked dynamically, by using the
4538 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4539 since it increases e2fsck's dependence on other files, but some
4540 people need to save disk space, and other critical programs on their
4541 systems were being linked dynamically anyway.
4542
4543 Programs such as fsck which didn't need to be linked against
4544 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4545 only link against libraries they actually need. Otherwise, those
4546 programs would require the presense of libraries that otherwise
4547 could be removed from a rescuse diskette.
4548
4549 The ss include files are now installed correctly so they can
4550 actually be used by another package.
4551
4552 If the profiling libraries are built, they are now installed on a
4553 "make install-libs".
4554
4555
Theodore Ts'o7f88b041997-04-26 14:48:50 +00004556E2fsprogs 1.03 (March 27, 1996)
4557===============================
4558
4559Change the m68k bit numbering for bitmasks to match the bit numbering
4560used by all other ext2 implementations. (This change was requested by
4561the m68k kernel development team.)
4562
4563Support (in-development) filesystem format revision which supports
4564(among other things) dynamically sized inodes.
4565
4566Fixed a bug in the ext2 library so that an intelligent error is
4567returned if mke2fs is run with a ridiculously small number of blocks
4568for a partition.
4569
4570Fixed a bug in the ext2 library which required that the device be
4571openable in read/write mode in order to determine its size. This
4572caused e2fsck -n to require read/write access when it was not
4573previously necessary.
4574
4575Fixed a bug in e2fsck which casued it to occasionally fail the test
4576suite depending on which version of the floating point library it was
4577using.
4578
4579Fixed a bug in e2fsck so that it now halts with a fatal error when
4580certain superblock consistency checks fail. Previously it continued
4581running e2fsck, with some potential confusing/damaging consequences.
4582
4583Added new flag to fsck which allows the root to be checked in parallel
4584with other filesytems. This is not the safest thing in the world to
4585do, but some system administrators really wanted it.
4586
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00004587Fixed -Wall flames in lib/ss.
4588
Theodore Ts'o74becf31997-04-26 14:37:06 +00004589
4590E2fsprogs 1.02 (January 16, 1996)
4591=================================
4592
4593Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4594
4595Change e2fsck to print statistics of how many non-contiguous files are
4596on the system. Note that a file which is larger than 8k blocks, it is
4597guaranteed to be non-contiguous.
4598
4599In mke2fs, print a warning message if a user tries to format a whole
4600disk (/dev/hda versus /dev/hda1). If a user really wants to format a
4601whole disk, the -F (force) option forces mke2fs to format a whole disk
4602as a filesytem.
4603
4604Fix a bug in fsck where in some cases it might start checking
4605partitions in the next pass before it finishes checking partitions in
4606the current pass. This still won't cause two partitions on the same
4607disk will be checked, so it's rarely a problem in real life.
4608
4609Patch lsattr so that it won't hang when checking a named pipe.
4610
4611Minor compilation fixes:
4612 * Fix the order of libraries that were linked in debugfs.
4613 * Allow the sources to be compiled with -ansi turned on.
