2=================================
3
4Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
5percentage of reserved blocks. (Addresses Debian Bug: #452639)
6
7Updated Spanish and Catalan translations.
8
9Fixed various Debian packaging issues --- see debian/changelog for
10details. (Addresses Debian Bugs: #483962, #483023)
11
12Add detection for ZFS volumes to the libblkid library.
13
14Fixed spelling mistakes, typos, and otherwise clarified man pages.

17Programmer's notes:
18-------------------
19
20Fix marginal C code in probe_lvm2() function to the blkid library more
21portable for older compilers.
22
23Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
24

30================================
31
32When deciding whether or not to revalidate a blkid cache entry, if the
33device's mtime is newer than the last time the cached entry was
34validated, force a revalidation.
35
36Fix a potential data corruption bug in e2fsck in the journal replay.
37The chances of this is happening is extremely remote, especially the
38default data=ordered or data=writeback modes. However, if a block
39which has been journalled starts with the first four bytes 0xc03b3998,
40when e2fsck replays the journal, those four bytes will be replaced
41with zero's. Fortunately, it is highly, highly unlikely for e2fsck
42metadata to begin with those fatal 4 byte sequence, and unless
43data=ordered mode is in use, data blocks are never journaled.
44
45Updated German, Dutch, Sweedish, and Vietnamese translations.

47Programmer's notes:

49
50Fixed various Debian packaging issues --- see debian/changelog for
51details.
52
53Remove default sizes of types when cross compiling, since autoconf
542.50 can figure this out automatically now.

58=================================
Theodore Ts'o5e107622008-03-14 14:29:51 -040059
60SuSE's security team audited uuidd and came up with a few minor
61issues. None of them are serious given that uuidd runs setuid as a
62unprivileged user which has no special access other than libuuid
63directory, but it's good to get them fixed.
64
65One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
66work correctly with in-inode extended attributes.
67
Theodore Ts'o7affded2008-04-27 00:53:27 -040068Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
69translations.
70
71Debugfs will avoid using a pager if the standard output is not a tty.
72
73Fix debugfs and tune2fs to correctly handle daylight savings time when
74parsing a time string.
75
76Fixed spelling mistakes, typos, and otherwise clarified man pages.
77
78Fix fsck completion bars when multiple filesystems were being checked
79in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
80#203323, Addresses Sourceforge Bug: #1926023)
81
82Fix fsck so that progress information is sent back correctly when
83multiple filesystems are being check and the output of fsck is being
84redirected to a file descriptor. Also, include the device name (w/o
85spaces) in the progress information sent back via a file descriptor.
86(Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
87#1926023)
88
89Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
90
91If logsave receives a SIGTERM or SIGINT signal, it will now pass that
92signal to its child process.
93
94Fix mke2fs's creation of are resize inode when there is a non-standard
95s_first_data_block setting.
96
97Fix bug in blkid when run by an unprivileged user; most devices were
98not reported correctly. 9Addresses Launchpad Bug: #220275)
99
100Mke2fs will not allow the logically incorect combination of
101resize_inode and meta_bg, which had previously caused mke2fs to create
102a corrupt fileystem.
103
104Fix fsck in German locales so that a 'j' means yes.

113
Theodore Ts'o7affded2008-04-27 00:53:27 -0400114Update valgrind options in test_script to work with valgrind 3.2.3
115
116Update texinfo.tex to a much newer version from the FSF.
117
118Remove bashism for configure script and from the lib/ss Makefile.
119Addresses Sourceforge Bug: 1921969
120
121Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
122
123Fix build system so that if texinfo is not installed, it won't print a
124(harmless) error message.

Theodore Ts'oda078322008-03-13 20:25:51 -0400127E2fsprogs 1.40.8 (March 13, 2008)
128=================================
129
130Fixed e2image -I so it works on image files which are larger than 2GB.
131
132Fixed e2fsck's handling of directory inodes with a corrupt size field. If
133the size is larger than the number of blocks found in the inode, don't
134try to allocate extra empty blocks at the end of the directory to make
135up the difference; there's no point to doing that. In addition, if
136the size is not a multiple of a blocksize, always fix it.
137
138E2fsck handled a pass 2 "should never happen error" by not giving
139enough information and then core dumping. Unfortunately, it was all
140too easy to trigger the "should never happen" situation if a
141directory's inode size was not correct. This has been fixed, but
142e2fsck has also been taught how to handle this situation more
143gracefully, by simply removing the inode hash tree information, so
144that it can be rebuilt again after e2fsck's pass 3. (Addresses
145Launchpad Bug: #129395)
146
147Resize2fs had a bug resizing large inodes with extended attributes
148that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
149completely on big-endian systems such as PowerPC. The bug should be
150completely fixed now. Yay for regression test suites. (Addresses Red
151Hat Bugzilla: #434893)
152
153Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
154translations. Many thanks to Philipp Thomas from Novell for stepping
155up to become the new German translation maintainer! (Addresses Debian
156Bugs: #302512, #370247, #401092, #412882).
157
158When e2fsck is clearing a corrupt inode's HTREE directory information,
159make it clear that it is just clearing the HTREE information, not the
160entire inode.
161
162Fixed spelling mistakes, typos, and otherwise clarified man pages.
163
164Programmer's notes
165------------------
166
167Add new functions, ext2fs_dblist_get_last() and
168ext2fs_dblist_drop_last(), which allows the caller to examine the last
169directory block entry added to the list, and to drop if it necessary.
170
171Fixed a portability problem in libblkid with DJGPP.
172
173Fix an obvious typo in an "internal error" message in e2fsck. Thanks
174to Philipp Thomas for pointing this out.
175
176If the info files are not built, change "make install" so it doesn't
177fail with an error code.

Theodore Ts'oe1e83b62008-02-28 22:51:49 -0500180E2fsprogs 1.40.7 (February 28, 2008)
181====================================
182
183Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
184depreciate the -s option, since it can result in filesystems which
185e2fsck can't fix easily. There are very good reasons for wanting to
186disable sparse_super; users who wants to turn off sparse_super can use
187debugfs. (Addresses Sourceforge Bug: #1840286)
188
189Add missing options to mke2fs's usage message. (Addresses Sourceforge
190Bug: #1751393)
191
192Fix bug in resize2fs when large (greater than 128 byte) inodes are
193moved when a filesystem is shrunk; it was only moving the first 128
194bytes, so extended attributes were not getting moved. (Addresses Red
195Hat Bugzilla: #434893)
196
197E2fsck now prints an explicit message when the bad block inode is
198updated, to avoid confusion about why the filesystem was modified.
199(Addresses Sourceforge Bug: #756460)
200
201Allow mke2fs and tune2fs manipulate the large_file feature.
202Previously we just let the kernel and e2fsck do this automatically,
203but e2fsck will no longer automatically clear the large_file feature.
204It still isn't really necessary to worry about this feature flag
205explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
206#258381)
207
208Suppress message about an old-style fstab if the fstab file is empty.
209(Addresses Debian Bug: #468176)
210
211Fix (really minor) bug in debugfs's find_free_block so it avoids
212reporting a free block more than once if there are too few free blocks
213in the filesystem. (Addresses Sourceforge Bug: #1096315)
214
215Change e2fsck to no longer clear the LARGE_FILES feature flag
216automatically, when there are no more > 2GB files in the filesystem.
217It's been almost a decade since there have been kernels that don't
218support this flag, and e2fsck clears it quietly without telling the
219user why the filesystem has been changed.
220
221Fix bug which could cause libblkid to seg fault if a device mapper
222volume disappears while it is being probed. (Addresses RedHat
223Bugzilla: #433857)
224
225Inhance e2fsck's reporting of unsupported filesystem feature flags.
226(Addresses Sourceforge Feature Request: #1175808)
227
228Fix option syntax in dumpe2fs for explicit superblock and blocksize
229parameters. What was currently documented in the man page has been
230broken for some time, due to getopt() implementation changes. The
231option sytax has been changed to one which is can be more portable
232supported and which is consistent with the format for extended options
233in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
234
235Add support to tune2fs to clear the resize_inode feature. This
236requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
237
238Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
239Bugzilla: #409321)
240
241Add support for setting RAID stride and stripe-width via mke2fs and
242tune2fs. Teach dumpe2fs to print the RAID parameters.
243
244Add support for setting new superblock fields to debugfs's
245set_super_value.
246
247Add support for printing "mostly-printable" extended attributes in
248Debugfs.
249
250Add support for the -M option to fsck, which causes it to ignore
251mounted filesystem.
252
253Fix uuidd so that it creates the pid file with the correct pid number.
254(Addresses Sourceforge Bug: #1893244)
255
256Fix various gcc -Wall warnings.
257
258Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
259
260Fixed spelling mistakes, typos, and otherwise clarified man pages.

264Programmer's notes:
265-------------------
266
267Fixed various Debian packaging issues --- see debian/changelog for
268details. (Addresses Debian Bug: #466929)
269
270Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
271partially filled-in filesystem object on an error, so that e2fsck can
272print more intelligent error messages.
273
274Add a new function e2p_edit_feature2() which allows the caller to
275specify which feature flags are OK to set or clear, and which returns
276more specific information about feature flags which are not allowed to
277be set/cleared.
278
279Set the C locale in the test_script driver since it uses [A-Za-z].
280(Addresses Sourceforge Bug: #1890526)
281
282Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
283support lockf().
284
285Change configure.in to avoid using the 'dc' command unless it is
286absolutely needed. (i.e., when using parsing a WIP-style version
287number) (Addresses Sourceforge Bug: #1893024)
288
289Add portability checks to support compilation under DJGPP.
290
291Update to the latest samba tdb code before the LGPLv3 change, which
292fixes a realloc() leak on failure.
293
294Fix memory leak in ext2fs_alloc_block().
295
296Fix makefile dependency issues for various install targets.
297(Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
298
299Improve descriptions for the r_move_itable and r_resize_inode tests.

303===================================
304
305Add support for returning labels for UDF filesystems in the blkid
306library.
307
308Fix bug in the blkid library where cached filesystems was not being
309flushed when opening USB devices returned the error ENOMEDIUM.
310(Addresses Debian Bug: #463787)
311
312Added logic to the blkid library to automatically choose whether a
313filesystem should be mounted as ext4 or ext4dev, as appropriate.
314
315Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
316
317Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
318configured with --enable-jbd-debug.
319
320Document the BLKID_FILE environment variable in the libblkid man page
321
322Programmer's Notes:
323-------------------

325Update e2fsprogs translation template and Vietnamese and Czech translations
326
327Fixed various Debian packaging issues --- see debian/changelog for
328details. (Addresses Debian Bugs: #436058)
329
330Don't try to create $DESTDIR/etc/init.d as part of make install as we
331don't install the init.d script (and it's not the recommended way to
332start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
333
334Use thread local storage to fix a theoretical race condition if two
335threads try to format an unknown error code at the same time in the

Theodore Ts'oc8a57082008-01-27 20:01:25 -0500339E2fsprogs 1.40.5 (January 27, 2008)
340===================================
341
342Fix a potential overflow big in e2image if the device name is too
343long.
344
345Mke2fs will now create new filesystems with 256 byte inodes and the
346ext_attr feature flag by default. This allows for much better future
347compatibity with ext4 and speeds up extended attributes even on ext3
348filesystems.
349
350Teach e2fsck to ignore certain "safe" filesystem features which are
351set automatically by the kernel. Having the kernel set features
352automagically behind the user's back is a bad idea, and we should try
353to break the kernel of this habit, especially for the newer ext4
354feature flags. But for now, we will try to avoid needless full checks
355which can annoy users who are doing fresh installs.
356
357Add support in tune2fs and mke2fs for making a filesystem as being "ok
358to be used with test kernel code". This will be needed for using test
359filesystems with the latest ext4 kernel code.
360
361Change e2fsck -fD so that it sorts non-htree directories by inode
362numbers instead of by name, since that optimizes performances much
363more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
364
365If e2image fills the disk, fix it so it exits right away instead of
366spewing large numbers of error messages.
367(Addresses-Sourceforge-Feature-Request: #606508)
368
369If ftruncate64() is not available for resize2fs, let it use ftrucate()
370instead, but have it check to see if the size would get truncated, and
371skip calling ftruncate in that case.
372
373Add support for detecting HFS+ filesystems in the blkid library.
374
375Add supprt in the blkid library for ext4/ext4dev filesystems.
376
377Fix a bug in blkid where it could die on a floating point exception
378when presented with a corrupt reiserfs image.
379
380Fix blkid's handling of ntfs UUID's so that leading zeros are printed
381such that UUID string is a fixed length.
382
383Add sample python bindings for the uuid library to the contrib
384directory. (Addresses-Sourceforge-Patches: #778817)
385
386Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
387will work with large files. (Addresses Sourceforge Feature Request:
388#1257500 and Sourceforge Support Request: #1253511)
389
390Allow the debugfs 'undel' command to undelete an inode without linking
391it to a specific destination directory, since this might require
392allocating blocks that could overwrite some yet-to-be-recovered
393deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
394
395Update Swedish translations from the Translation Project.
396
397Programmer's Notes:
398-------------------
399
400Fix configure handling of --sbindir (which should rarely be used, but
401someone did complain, so let's fix it). (Addresses Sourceforge Bug:
402#498381)
403
404Updated e2fsprogs.spec file to include a new uuidd package
405
406Use pkg-config to determine where to find the devmapper library so we
407can find out where it is located on different distributions.
408
409Fix Makefile race so that "make -j3 distclean" works correctly
410
411Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
412especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
413#1819034, #1863819)
414
415Fixed spelling mistakes, typos, and otherwise clarified man pages.
416
417Fixed various Debian packaging issues --- see debian/changelog for
418details. (Addresses Debian Bugs: #459403, #459475, #459614)
419
420Remove the --enable-dynamic-static configure option, and build e2fsck
421dynamically by default. If the user wants e2fsck.static, he/she will
422need to build it via "make -C e2fsck e2fsck.static"

429====================================
430
431Improve time-based UUID generation. A new daemon uuidd, is started
432automatically by libuuid if necessary. This daemon is setuid to allow
433updates to /var/lib/libuuid, so the clock sequence number can be
434stored and so if the clock is set backwards, it can be detected.
435(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
436#233471)
437
438Filter out the NEEDS_RECOVERY feature flag when writing out the backup
439superblocks. This avoids e2fsck from concluding that a full
440filesystem check is required before backing up the superblock due to
441changes in the feature flags. (Addresses Debian Bug: #454926)
442
443Fix fsck to only treat the '#' character as a comment at the beginning
444of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
445will cause fsck to issue an bogus warning message.
446(Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
447
448Format control characters and characters with the high eighth bit set
449when printing the contents of the blkid cache, to prevent filesystems
450with garbage labels from sending escape sequences to the user's screen
451that might, for example place it in graphics mode. (Addresses Ubuntu
452Bug: #78087)
453
454Fix sign-extension problem on 64-bit systems in in the com_err
455library. (Addresses Sourceforge Bug: #1809658)

484===================================
485
486Fix a potential security vulnerability where an untrusted filesystem
487can be corrupted in such a way that a program using libext2fs will
488allocate a buffer which is far too small. This can lead to either a
489crash or potentially a heap-based buffer overflow crash. No known
490exploits exist, but main concern is where an untrusted user who
491possesses privileged access in a guest Xen environment could corrupt a
492filesystem which is then accessed by the pygrub program, running as

494gain privileged access in the host OS. Thanks to the McAfee AVERT
495Research group for reporting this issue. (Addresses CVE-2007-5497.)
496
497Fix hueristics in blkid which could cause a disk without partitions to
498be incorrectly skipped when a loopback device is present. (Addresses
499Red Hat Bugzilla #400321.)
500
501Fix e2image so that in raw mode it does not create an image file which
502is one byte too large.
503
504Change mke2fs's usage message so it recommends the preferred -E option
505instead of the deprecated -R option.
506
507Enhance the blkid library so it will recognize squashfs filesystems.
508(Addresses Red Hat Bugzilla #305151.)
509
510Enhance e2fsck so it will force the backup superblocks to be backed up
511if the filesystem is consistent and key constants have been changed
512(i.e., by an on-line resize) or by e2fsck in the course of its
513operations.
514
515Enhance blkid's detection of FAT filesystems; so that USB disks with
516only a single bootable partition will not get missed.
517
518E2fsck will no longer mark a filesystem as invalid if it has time
519errors (i.e., if superblock mount time or last write time is in the
520future) and the user refuses to fix the problem.
521
522The Ubuntu init scripts don't properly set the system time correctly
523from hardware clock if the hardware clock is configured to tick local
524time instead of GMT time. Work around this as best as we can by
525providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
526be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
527Bug #131201.)
528
529Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
530Hat Bugzilla #151533.)
531
532Fix e2fsck so that if the superblock is corrupt, but still looks
533vaguely like an ext2/3/4 superblock, that it automatically tries to
534fall back to the backup superblock, instead of failing with a hard
535error.
536
537Make the e2fsprogs program more robust so that they will not crash
538when opening a corrupt filesystem where s_inode_size is zero.
539
540Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
541arguments are detected as such and the parse error is reported to the
542user. (Addresses Debian Bug #435381.)
543
544Change e2fsck so it will not complain if a file has blocks reallocated
545up to the next multiple of a system's page size.
546
547Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
548about (valid) filesystems where the inode table extends to the last
549block of the block group. (Addresses Red Hat Bugzilla #214765.)
550
551Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
552allocating inode tables for some relatively rare odd disk sizes.
553(Addresses Red Hat Bugzilla #241767.)
554
555Add Catalan translation and update Dutch and Swedish translations
556from the Translation Project.
557
558Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
559still had an issue when trying to figure out whether we need to
560byte-swap fast symlinks that contained extended attributes.

566Programmer's Notes:
567-------------------
568
569Fix mke2fs tests to avoid needing any significant ^M (CR) characters
570
571Add "make check" to the RPM spec file
572
573Fix "make install" and 'make unstall" in misc/Makefile.in so that it
574works correctly when the prefix is not the root directory.
575
576Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
577clena up after themselves by deleting the test.img temporary file
578after completing the test.
579
580Fixed a corner case bug ext2fs_unlink() when trying to delete the
581first directory entry in a directory block and the last directory
582entry in the previous directory block is not in use. Fortunately
583ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
584places where it is extremely unlikely to run into this corner case.
585
586Fix missing dependency which would cuase parallel builds to fail.
587(Addresses Sourceforge Bug #1842331.)
588
589Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
590calling open(O_CREATE) with a missing mode parameter.
591
592Fix the test_ss.c in lib/ss so it can be used as an example
593application program for the library as well as a regression test
594suite.
595
596Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
597are properly passed back up through the call stack.

600================================
601
602A recent change to e2fsck_add_dir_info() to use tdb files to check
603filesystems with a very large number of filesystems had a typo which
604caused us to resize the wrong data structure. This would cause a
605array overrun leading to malloc pointer corruptions and segfaults.
606Since we normally can very accurately predict how big the the dirinfo
607array needs to be, this bug only got triggered on very badly corrupted
608filesystems.
609
610Fix a bug in e2fsck which caused it to incorrectly salvange
611directories when the last entry's rec_len is bogusly too big. This
612resulted in a nonsense filesystem corruption to be reported, and
613required a second run of e2fsck to fully fix up the directory.
614
615Update tune2fs man page to include more discussion of reserved blocks
616(Addresses Launchpad bug #47817)

623===============================
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400624
625Fix bug which could cause libblkid to loop forever. When revalidating
626a partition where there is obsolete information in /etc/blkid.tab, we
627end up freeing a the type tag without clearing dev->bid_type, causing
628blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
629
630The Turkish translation has a bug in it where it has the translation
631of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
632@E, recursively, forever, until the stack fills up and e2fsck core
633dumps. We fix this by making e2fsck stop @-expansions after a
634recursive depth of 10, which is far more than we need.
Theodore Ts'od2dc78a2007-07-14 09:03:17 -0400635(Addresses Sourceforge Bug: #1646081)
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400636
637Compile the default mke2fs.conf into mke2fs program. People are
638getting surprised by mke2fs creating filesystems with different
639defaults than earlier versions of mke2fs if mke2fs.conf is not
640present. So we now create a built in version of mke2fs.conf file
641which is used by mke2fs if the /etc/mke2fs.conf is not present.
642(Addresses SourceforgeBug: #1745818)
643
644Improve the config/parse_types.sh helper script. Fix a potential
645security problem if e2fsprogs is built as root (as Gentoo does!). In
646addition fix the script and how it is called from the configure script
647so that it does the right thing when cross-compiling. (Fixes Gentoo
648bug: #146903)
649
650Update Vietnamese, French, and Dutch PO files from the Translation
651Project. Also created a new e2fsprogs.pot file for translator.
652
653Fix bogus strip permission errors when building under Debian. When
654building the e2fsprogs dpkg's, the dh_strip command emits a large
655number of error messages caused by the permissions not being right.
656So run dh_fixperms before running dh_strip.

658Programmer's Notes:
659-------------------
660
661Add new function: profile_set_default(). This function sets the value
662of the pseudo file "<default>". If the file "<default>" had
663previously been passed to profile_init(), then def_string parameter
664will be parsed and used as the profile information for the "<default>"
665file.
666
667Fix mk_cmds's error reporting so that it is unambiguous that it is the
668mk_cmds script which is generating the error. (Obviates Gentoo patch:
669e2fsprogs-1.32-mk_cmds-cosmetic.patch)
670
671Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
672priority" environment variable that overrides all others, where as
673LANG is the lowest priorty environment variable. If LC_ALL is set, it
674doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
675the all the rest are set. This will assure that the locale when
676running the test suites is the "C" locale. (Obviates Gentoo patch:

685Add new blkid -g option which causes the blkid cache to be garbage
686collected.
687
688Fix a bug in libblkid which could cause the internal field bid_type to
689become corrupted. Fortunately bid_type isn't used much, and bid_label
690and bid_uuid is only used by debugging code, so the impact of this bug
691was very minor.
692
693Mke2fs will now store the RAID stride value when a filesystem is
694created with a requested RAID stride, and then use it automatically in
695resize2fs.
696
697Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
698isn't too big. In some cases Lustre users have tried specifying an
699inode size of 4096 bytes, while keeping an inode ratio of one inode
700per 4096 bytes.
701
702Improve sanity check in e2fsck's algorithm for finding a backup
703superblock, so that it won't accidentally find a superblock that was
704located in the journal, and then later reject it as being not a valid
705backup superblock.
706
707Fix e2fsck get_size logic so that it will work with the Linux floppy
708driver. The Linux floppy driver is a bit different from the other
709block device drivers, in that if the device has been opened with
710O_EXCL, it disallows another open(), even if the second open() does
711not have the O_EXCL flag. (Addresses Debian Bug: #410569)
712
713Fix error checking of badblock's last-block and start-block arguments.
714(Addresses Debian Bug: #416477)
715
716Fix e2fsck so that it doesn't overwrite the backup superblocks when
717recovering a journal until the master superblock has been confirmed as
718being sane.
719
720Change the blkid library to be much more paranoid about concluding
721that a partition contains an NTFS filesystem, and fetch the UUID and
722LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
723#110138)
724
725Factor out the code which sets the default journal size and move it
726into libext2fs.
727
728Enhance e2fsck so it will recreate the ext3 journal if the original
729journal inode was cleared to due it being corrupt after finishing the
730filesystem check.
731
732Fix e2fsck so that it updates the journal inode if it is corrupted and
733the backup journal information from the superblock was successfully
734used to recover the filesystem.
735
736Fix e2fsck so that it checks all of the blocks in the journal inode
737for validity. The original code only checked the direct blocks to
738make sure the journal inode was sane. Unfortunately, if some or all
739of the indirect or doubly indirect blocks were corrupted, this would
740not be caught.
741
742Add support in blkid to detect LUKS encrypted partitions.
743
744Add extra sanity checks for extended attributes in the case where the
745size is zero but the offset is very large.
746
747Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
748and ext2fs_get_next_inode_full().
749
750Clarify the copyright licenses used by the various libraries in
751the top-level COPYING file (Red Hat Bugzilla: 166058)
752
753Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
754
755Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
756
757Remove check in e2fsck which requires EA's in inodes to be sorted;
758they don't need to be sorted, and e2fsck was previously wrongly
759clearing unsorted EA's stored in the inode structure.
760
761Allow mke2fs or tune2fs to create a substantially larger journal (up
762to 10,240,000 blocks).
763
764Fix MD superblock detection, and make sure the correct UUID is
765reported from the MD superblock.
766
767Fix a signed vs. unsigned bug in debugfs.
768
769Enhance debugfs's date parser so that it accepts integer values.
770
771Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
772file with multiply claimed blocks is hard linked. or not at all if the
773root directory contains shared blocks
774
775Enhance debugfs so it can modify the block group descriptors using the
776command set_block_group_descriptor.
777
778Improve e2fsck's reporting of I/O errors so it's clearer what it was
779trying to do when an error happens
780
781Fix a bug in in how e2fsprogs byte swaps inodes containing fast
782symlinks that have extended attributes. (Addresses Red Hat Bugzilla:

802Fix e2fsck to set the file type of the '..' entry when connecting
803a directory to lost+found. (Addresses Lustre Bug: #11645)
804
805Enhance e2fsck to recover directories whose modes field were corrupted
806to look like special files. This is probably only useful in
807artificial test cases, but it will be useful if we ever do the "inodes
808in directory" idea for ext4.
809
810Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
811#412614)
812
813Fix resize2fs parsing of size parameter (in sector units). This was
814actually a bug in libe2p's parse_num_blocks() function. When handling
815the 's' suffix, it was ignoring the blocksize information passed in
816from the caller and always interpreting the number in terms of a 1k
817blocksize. (Addresses Debian Bug: #408298)
818
819There was a floating point precision error which could cause e2fsck to
820loop forever on really big filesystems with a large inode count.

822
823Fix memory leak in ext2fs_write_new_inode()

949work. (Addresses SourceForge Bug: #1532177)
950
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400951Added the 64-bit byte swapping function ext2fs_swab64().
952
953Added two new helper functions to prevent 2**31/2**32-1 overflow
954problems: ext2fs_div_ceil() and e2p_percent().
955
956Create new ext2fs library inline functions ext2fs_group_first_block()
957and ext2fs_group_last_block() in order to calculate the starting and
958ending blocks in a block group.
959
960Create the generated files read-only to remind developers not to edit them.
961
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500962Add support for autoconf 2.60 (with backwards compatibility for older
963versions of autoconf).
964
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400965Added an "make rpm" target to top-level Makefile
966
967Added various FreeBSD portability fixes.
968
969Exclude mercurial files from the RPM build tree to speed up copy/build.
970
971Use root_sysconfdir to define the locations of mke2fs.conf and
972e2fsck.conf instead of using a hard-coded /etc pathname.
973
974Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
975
976Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
977
978If diff -u is supported, use it to report test failures.
979
980Updates/improvements to RPM spec file
981
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500982Add on-disk format definitions for the following new features:
983EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
984EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
985EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
986
987Add a new make target "checked-failed" in the tests directory which
988reruns any failed tests
989
990Update draft-leach-uuids-guids-01.txt with rfc4122.txt
991
Theodore Ts'oa0d42542007-04-07 11:05:10 -0400992Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
993pointer dereferences, memory leaks, etc. None were security-criticial
994problems.
995
996Fix up usage and decrement error messages in the test_icount program
997
998Add debugging code to the com_err library; if the environment variable
999COMERR_DEBUG is set to 1, print out debugging messages as error tables
1000are added and removed from the com_err library. If the
1001COMERR_DEBUG_FILE environment variable is set (and the process is not
1002setuid) the debugging messages may be redirected to a file.
1003
1004Change all of the e2fsprogs programs to use the newer add_error_table()
1005and remove_error_table() interfaces instead of the much older
1006initialize_*_error_table() function.
1007
1008Add TDB support into the ext2fs library. This allows us to have a
1009guaranteed library we can count on always being present so we can
1010store data in an on-disk database.
1011
1012Add support for using TDB to store the icount data, so we don't run out
1013of memory when checking really large filesystems.
1014
Theodore Ts'od7b64722007-06-24 17:32:47 -04001015Change the regression test suite so that it skips empty test directories.
1016
1017Define the l_i_iversion field in ext2_inode. The l_i_version field is
1018now defined from the old l_i_reserved1 field in the ext2 inode. This
1019field will be used to store high 32 bits of the 64-bit inode version
1020number.
1021
1022Add Makefile production rule for e2fsprogs.spec in case it gets
1023deleted.
1024
1025Add new function profile_get_uint() to allow for a clean way to fetch
1026unsigned integers from the context.
1027
1028Add test to make sure the ext2 superblock structure is 1024 bytes.
1029
1030Fix typo in name of f_dup4 regression test
1031
1032Add new function blkid_gc_cache() which performs a garbage collection
1033pass on the /etc/blkid.tab file.
1034
1035The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
1036general, only e2fsck (after the filesystem is clean), tune2fs, and
1037resize2fs should change the backup superblocks by default. Most
1038callers of ext2fs_open() should not be touching any superblock fields
1039which require the backups to be touched.
1040
1041Add new function to libext2fs, ext2fs_default_journal_size(), which
1042returns the default journal size.
1043
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001044
Theodore Ts'o6c094752006-05-29 11:47:25 -04001045E2fsprogs 1.39 (May 29, 2006)
1046=============================
Theodore Ts'o34a26112006-03-29 20:40:23 -05001047
Theodore Ts'o34a26112006-03-29 20:40:23 -05001048Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
1049between 2**31 and 2**32 blocks.
1050
Theodore Ts'o34a26112006-03-29 20:40:23 -05001051Change mke2fs to use /etc/mke2fs.conf as a configuration file to
1052configure the filesystem features, blocksize, and inode_ratio for
1053different filesystem types.
1054
Theodore Ts'o6c094752006-05-29 11:47:25 -04001055Mke2fs will now create filesystems hash trees and on-line resizing
1056enabled by default, based on the new /etc/mke2fs.conf file.
1057
Theodore Ts'o34a26112006-03-29 20:40:23 -05001058The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
1059filesystem device node in exclusive mode to prevent accidents by
1060system administrators. In the case of resize2fs and mke2fs, it will
1061only use exclusive mode if the filesystem is not mounted.
1062
1063Fixed a bug in mke2fs which caused it to to fail when creating the
1064resize inode for large filesystems. (Addresses Debian Bug #346580)
1065
Theodore Ts'obae55642006-05-14 17:31:48 -04001066When allocating space for the RAID filesystems with the stride
1067parameter, mke2fs will now place each portion of the group's inode
1068table right up after the superblock (if present) in order to minimize
1069fragmentation of the freespace.
1070
1071Speed up mke2fs and e2fsck by writing inode and block bitmaps more
1072efficiently by writing the inode and block bitmaps in one pass, thus
1073reducing the number of disk seeks required.
1074
Theodore Ts'o34a26112006-03-29 20:40:23 -05001075Add support for on-line resizing to resize2fs.
1076
1077Fix blkid library so that logic to determine whether or not a device's
1078cached information in /etc/blkid.tab needs to be verified or not
1079doesn't get confused by a system clock which is insane (for example,
1080if the battery is dead on a Macintosh running PPC Linux. (Addresses
1081Red Hat Bug: #182188)
1082
1083The blkid library will now store the UUID of the external journal used
1084by ext3 filesystems, so that in the future, the userspace mount binary
1085can use this to find the location of the external journal and pass
1086this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -05001087
1088E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -05001089control how various options should be handled. See the e2fsck.conf
1090man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -05001091
Theodore Ts'o34a26112006-03-29 20:40:23 -05001092E2fsck now prints an explanatory message when delaying a filesystem
1093check when the system is running on battery. (Addresses Debian Bug:
1094#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001095
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001096E2fsck will detect if the superblock's last mount field or last write
1097field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -05001098#327580) These problems will be fixed automatically in preen mode
1099since Debian's boot sequence bogusly doesn't set the time correctly
1100until potentially very late in the bootup process, and this can cause
1101false positives which will cause users' systems to fail to boot.
1102(Addresses Debian Bugs #343662 and #343645)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001103
Theodore Ts'o34a26112006-03-29 20:40:23 -05001104E2fsck now checks to see if the superblock hint for the location of
1105the external journal is incorrect, and if so, offer to update it.
1106(Addresses Debian Bug: #355644)
1107
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001108Fix e2fsck from segfaulting on disconnected inodes that contain one or
1109more extended attributes. (Addresses Debian Bug: #316736, #318463)
1110
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001111E2fsck will stop and print a warning if the user tries running a
1112read/write badblocks test on a read-only mounted root filesystem.
1113
Theodore Ts'obae55642006-05-14 17:31:48 -04001114Fix a memory leak in e2fsck's error paths. (Thanks to Michael
1115C. Thompson for pointing these out; they were originally found using
1116Coverity.)
1117
Theodore Ts'of3227852005-12-31 16:45:29 -05001118When resizing a file containing a filesystem, resize2fs will expand or
1119truncate a file as necessary. (Addresses Debian Bug: #271607)
1120
Theodore Ts'obae55642006-05-14 17:31:48 -04001121Resize2fs will now automatically determine the RAID stride parameter that
1122had been used to create the filesystem, and use that for newly created
1123block groups. The RAID stride parameter may also be manually specified
1124on the command line using the new -S option to resize2fs.
1125
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001126Fix mke2fs so that it correctly creates external journals on
1127big-endian machines (such as a S/390).
1128
Theodore Ts'obae55642006-05-14 17:31:48 -04001129Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
1130fail to print out the journal or hash seed UUID. (Thanks to Guillaume
1131Chambraud for pointing this out.)
1132
1133Dumpe2fs will now print the size of the journal (if present).
1134
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001135Fix debugfs's set_inode_field command so it can properly set the frag,
1136fsize, uid_high, gid_high, and author fields in the inode instead of
1137silently failing, and so that setting the i_size actually sets i_size
1138correctly.
1139
1140Add a new debugfs command, set_current_time, which sets fs->now so
1141that regression test suites can repeatedly modify the filesystem's
1142last_write fields.
1143
Theodore Ts'o34a26112006-03-29 20:40:23 -05001144Fix a bug in debugfs's icheck which would incorrectly report the owner
1145of an extended attribute block.
1146
Theodore Ts'obae55642006-05-14 17:31:48 -04001147Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
1148print a usage message when an illegal option character is given.
1149
Theodore Ts'o6c094752006-05-29 11:47:25 -04001150Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
1151so it won't core dump. (Addresses SourceForge bug #1424311)
1152
Theodore Ts'obae55642006-05-14 17:31:48 -04001153Fix mklost+found so that it creates a full-sized directory on
1154filesystems with larger block sizes.
1155
1156Fix a file descriptor leak in blkid library.
1157
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001158Fix a display bug in "badblocks -sv" so that the done message properly
1159clears the block number at the end of the test. (Addresses Debian Bug
1160#322231)
1161
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001162Allow fractional percentages to the -m option in mke2fs and tune2fs
1163(Addresses Debian Bug: #80205)
1164
1165Use fstat/fstat64 in getsize.c if the the target is a regular file,
1166instead of attempting to do a binary search. Fix some fd leaks in
1167error cases.
1168
Theodore Ts'o34a26112006-03-29 20:40:23 -05001169Add support for device mapper library to the blkid library to ensure
1170that the "best" (i.e., leaf) device is probed by the blkid library.
1171
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001172Fix the blkid library so that it notices when an ext2 filesystem is
1173upgraded to ext3.
1174
1175Improve the blkid's library VFAT/FAT detection; it now understands
1176labels stored in the root directory, and is more paranoid about
1177checking the FAT superblock values.
1178
Theodore Ts'o34a26112006-03-29 20:40:23 -05001179Fixed a fd leak in the uuid library which was causing problems for the
1180LVM tools. (Addresses Debian Bug: #345832)
1181
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001182Add support for the reiser4 and software suspend partitions to the
1183blkid library. Also add support for extract the label from iso9660
1184filesystems.
1185
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001186Fix a compile_et bug which miscount the number of error messages if
1187continuations are used in the .et file.
1188
1189Add extra sanity checks to protect users from unusual cirucmstances
1190where /etc/mtab may not be sane, by checking to see if the device is
1191reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
1192#319002)
1193
Theodore Ts'o34a26112006-03-29 20:40:23 -05001194Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
1195Bug: #343149, #341911, #300871, #316604, #316782, #330789)
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001196
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001197Fix use-after-free bug in e2fsck when finishing up the use of the
1198e2fsck context structure.
1199
Theodore Ts'o34a26112006-03-29 20:40:23 -05001200Fixed spelling mistakes, typos, and otherwise clarified man pages and
1201documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

1211Programmer's notes:
1212-------------------
1213
Theodore Ts'o7e2ec012006-04-22 04:29:16 -04001214Update config.guess and config.sub to latest version (2006-02-23) from
1215FSF.
1216
1217Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
1218Bugs: #360661, #360317)
1219
Theodore Ts'o34a26112006-03-29 20:40:23 -05001220Fixed the Makefile so that they work correctly on newer versions of
1221GNU make (i.e., 3.81).
1222
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001223Add valgrind support to the regression test suites, and eliminate
1224false positives from valgrind.
1225
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001226Add a regression test suite for the blkid library.
1227
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04001228Fix a fencepost error in resize2fs caught by valgrind.
1229
Theodore Ts'o4c02c412005-12-09 19:20:01 -05001230Fix compiler warnings about missing memcpy prototypes.
1231
1232We no longer have the sparc assembly code in the header file any more,
1233so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
1234break compiles on the sparc architectures when using gcc.
1235
1236In the libext2fs library, add the new field fs->now which if non-zero
1237is used instead of the system time when setting various filesystem
1238fields (last modified time, last write time, etc.)
1239
1240Fix gcc 4.01 complaints by adding a missing #include <string.h> to
1241ext2fs.h which is needed since the inline functions use memcpy().
1242(Addresses Sourceforge Bug #1251062)
1243
1244Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
1245the build system when building files in the util directory which are
1246needed during the build process. This avoids potential problems when
1247cross-compiling and some of the options specified in CFLAGS or LDFLAGS
1248are not recognized as valid by the host compiler. (Addresses
1249Sourceforge Bug #1261547)
1250
1251Clean up the blkid library by making the superblock and generic i/o
1252functions to be more generic. Clean up interface to the probe
1253function, and fix memory leak. Finallly, remove an unneeded reference
1254to probe.h in the lib/blkid/resolve.c
1255
Theodore Ts'o3285a9c2005-12-10 23:05:30 -05001256Add an ext2fs_read_bb_FILE regression test to confirm proper detection
1257of invalid block #'s.
1258
Theodore Ts'o34a26112006-03-29 20:40:23 -05001259The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
1260indicate that the the function read/writes the memory location.
1261
Theodore Ts'o3285a9c2005-12-10 23:05:30 -05001262Fix various gcc -Wall complaints.
1263
1264Add a dependency to make sure that the subdirectories are created
1265before creating all of the object files, in order to address parallel
1266build problem in the library Makefiles. (Addresses Sourceforge Bug:
1267#1261553)
1268
1269Add $(LDFLAGS) to the command line argument when generating an ELF or
1270Solaris shared library, to allow cross-compile and other builds that
1271might need to specify -L paths to needed libraries. (Addresses
1272Sourceforge Bug #1261549)
1273
Theodore Ts'obae55642006-05-14 17:31:48 -04001274Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
1275intended for testing purposes. It allows an ext2/ext3 developer to
1276create very large filesystems using sparse files where most of the
1277block groups are not initialized and so do not require much disk
1278space. Eventually it could be used as a way of speeding up mke2fs and
1279e2fsck for large filesystem, but that would be best done by adding an
1280RO_COMPAT extension to the filesystem to allow the inode table to be
1281lazily initialized on a per-block basis, instead of being entirely
1282initialized or entirely unused on a per-blockgroup basis.
1283
Theodore Ts'o6c094752006-05-29 11:47:25 -04001284Fix backwards compatibility so e2fsprogs will better compile on Linux
12852.0.35 systems.
1286
1287Make test scripts more robust against locale-related environment variables
1288
1289Fix type warning problem with sizeof() in ext2fs_open2().
1290

Theodore Ts'ofea95ff2005-07-01 17:31:55 -05001294E2fsprogs 1.38 (June 30, 2005)
Theodore Ts'o1f965c82005-06-30 20:06:45 -04001295==============================
1296
1297Fix blkid's test programs (built with "make check") compile correctly
1298even without "configure --enable-blkid-debug".
1299
1300Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
1301type aliasing rules on newer gcc compilers. (Addresses Red Hat
1302Bugzilla ##161183.)
1303
1304Fix com_err library to make it more compatible with recent changes
1305made to the com_err library in MIT Kerberos V5 version 1.4.
1306(Addresses Sourcefroge Bug #1150146)
1307
1308General cleanup of messages printed by e2fsprogs programs for grammar,
1309consistency, and to make life easier for translators. Fixed a few
1310strings containing English that had not been marked as needing
1311translations. Removed strings that do not need to be translated, to
1312make life easier for translators.
1313
1314Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
1315test to see if a device appears to be in use instead of just relying
1316on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
1317
1318Fix portability problem in the filefrag program affecting platforms
1319where the size of an integer is smaller than the size of a long.
1320(Addresses Debian Bug #309655)
1321
1322Mke2fs will now use a larger journal by default for filesystems
1323greater than 4GB. (128 MB instead of 32MB).
1324
1325Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
1326unless forced. This is to avoid signed vs. unsigned kernel bugs in
1327block numbers that still need to be fixed.
1328
1329The blkid program has a new option which will more efficiently search
1330for device when it is known (or expected) that only one matching
1331device will be found in the system, such as when doing a lookup by
1332UUID.
1333
1334Debian's e2fsprogs-specific initrd fragment will avoid including
1335unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
1336and LD_LIBRARY_PATH, and filtering out libraries found in
1337/etc/ld.so.preload. (Addresses Debian Bug: #304003)
1338
1339Fixed a potential portability issue in the blkid programs for
1340architectures where the char type is unsigned. (Addresses Sourceforge
1341Bug: #1180585)
1342
1343Fix a bug in filefrag so that it doesn't falsely count an extra
1344discontinuity when the first block found is an indirect block.
1345(Addresses Debian Bug #307607).
1346
1347Fix blkid's recognition of cramfs filesystems, and enhance it to be
1348able to handle cramfs labels.
1349
1350Fix debugfs's stat command to not core dump when a filesystem is not
1351open.
1352
1353Fix e2fsck's handling of error conditions caused by the resize inode
1354claiming blocks that are also used by other inodes, a filesystem
1355corruption which was commonly caused by a bug in Fedora Core 3's
1356resize2fs program.
1357
1358Fixed bug in filefrag which caused it to fail on non-ext2/3
1359filesystems. (Addresses Debian Bug: #303509)
1360
1361If the superblock last mount time indicates that the system clock may
1362not be accurate, then e2fsck will omit checking inodes' deletion time
1363field for indications of a potential corrupted orphaned inode list.
1364(Previously e2fsck only ommited these LOW_DTIME checks when the
1365superblock's last write time looked insane.)
1366
1367Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
1368(Addresses Debian bug #302200)
1369
1370Make the blkid library more paranoid about being run from setgid
1371programs, and to use __secure_getenv() from libc if it is available.
1372
1373Fixed spelling mistakes, typos, and otherwise clarified man pages.
1374(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
1375and Sourceforge Bug: #1189803)
1376
1377Updated and fixed translations.
1378
1379Fixed various Debian packaging issues --- see debian/changelog for
1380details.
1381
1382Programmer's notes:
1383-------------------
1384
1385Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
1386changed to take an unsigned int for the bit number. Negative bit
1387numbers were never allowed (and didn't make any sense), so this should
1388be a safe change. This is needed to allow safe use of block numbers
1389greater than or equal to 2**31.
1390
1391The compile_et program will avoid recreating generated foo_err.c and
1392foo_err.h files if no changes are necessary. The compile_et program
1393will also atomically replace these files to avoid a potential parallel
1394build race problem on SMP systems. (Addresses Sourceforge Bug:
1395#1157933)
1396
1397Added a new function to the blkid library, blkid_probe_all_new(),
1398which only probes newly added disk devices, and change
1399blkid_find_dev_with_tag() to use this function so that when a
1400requested tag is not found, devices that were previously not checked
1401are searched before searching all devices in the system.
1402
1403Added new functions to the blkid library, blkid_dev_set_search() and
1404blkid_dev_has_tag().
1405
1406E2fsck's problem strings can now use @m and @n as abbrevations for
1407"multiply-claimed" and "invalid", respectively.
1408
1409The e2fsprog.pot file now has an explanation of how the @-expansion
1410and %-expansion works, and strings in e2fsck/problem.c which contain @
1411characters now have comments in e2fsprogs.pot with the @-expansion to
1412make life easier for translators.
1413
1414Fixed missing return values in the ext2fs library which could cause it
1415to return random garbage in certain error conditions.
1416
1417Allow the current time to be overriden via the E2FSCK_TIME environment
1418variable for use in regression tests.
1419
1420The test scrpit driver program now exits with a non-zero status if
1421there any of its test that it ran failed.
1422
1423Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
1424Bug: #1157933)
1425
1426Fixed "make check" so that it compiles correctly even when e2fsprogs'
1427header files have not be installed in the system include directories.
1428(Addresses Sourceforge Bug: #1180572)
1429
1430Fixed gcc -Wall nits.
1431
1432
Theodore Ts'ofd4b28e2005-03-21 22:37:03 -05001433E2fsprogs 1.37 (March 21, 2005)
1434===============================
1435
1436Add support for checking the validity of Extended Attributes stored in
1437inodes to e2fsck.
1438
1439Add support for dumping the contents of large inodes to debugfs,
1440including the extended attributes stored in inodes.
1441
1442Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1443when we create a new inode we make sure that the extra information in
1444the inode (any extra fields in a large inode and any ea-in-inode
1445information) is initialized correctly. This can take place when
1446mke2fs creates the root and lost+found directory, when e2fsck creates
1447a new root inode or a new lost+found directory, and when the user uses
1448the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1449create inode could inherit garbage (or old EA information) from a
1450previously deleted inode.
1451
1452Fixed a bug in e2fsck so it would notice if a file with an extended
1453attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1454to zero.
1455
1456Added support to filefrag to detect files which are using the new
1457experimental file extents format, and use the non-ext2 algorithm in
1458that case. Fixed a bug to avoid reporting a false discontinuity if
1459there is one or more unallocated blocks at the beginning of a file.
1460
1461Duplicated a check for noticing whether or not the number of blocks
1462(given a certain blocksize) is greater than 2**32 when the
1463BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1464allows mke2fs to automatically use a larger blocksize when creating a
1465filesystem on a very large device when run on systems that do not
1466support BLKGETSIZE64.
1467
1468Fix the I18N build which was broken in e2fsprogs 1.36 because the
1469build system had been switched to treat the .gmo files as shipped
1470files (for backwards compatibility with systems that have older GNU
1471I18N tools installed), but the gen_tarball.in script was still
1472removing the .gmo files from the official source distribution.
1473
1474Fixed various Debian packaging issues --- see debian/changelog for
1475details. (Addresses Debian Bugs ##296769, #299341)
1476
1477Programmer's notes:
1478-------------------
1479
1480Added new functions to the e2p library which convert between a string
1481and os_type: e2p_os2string() and e2p_string2os(), and used them to
1482make the generated binaries more compact.
1483
1484Fixed a compile-time error on Darwin systems.
1485
1486Cleaned up the lib/ext2fs Makefile slightly.
1487
1488
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001489E2fsprogs 1.36 (February 4, 2005)
1490=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001491
1492All of the patches that were applied to Fedore Core 3's
1493e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1494lot of bug fixes first. Users of Fedora Core 3 are strongly
1495encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1496
1497Add support for filesystem with the online resizing via resize inode
1498feature. Fixed numerous bugs from the Fedora patches. The Fedora
1499patches also didn't bother to do any consistency checking on the
1500resize inode, or add any tests to the regression test suite. The "-R
1501resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1502being listed in mke2fs's usage message. All of these shortcomings
1503have been corrected.
1504
1505E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1506program. In order to do this, the user must run the commands:
1507
Theodore Ts'od0a3b462005-05-05 22:57:44 -04001508 debugfs -w /dev/hdXXX -R "features ^resize_inode"
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001509 e2fsck -f /dev/hdXXX
1510
1511Optionally, the ext2prepare command can be used to re-enable online
1512resizing after the filesystem has been fixed.
1513
1514The fsck program will now accept an optional filedescriptor argument
1515to the -C option. (The Fedora version of this patch would sometimes
1516cause fsck to ignore a parameter on fsck's command line in some rare
1517cases, sigh.)
1518
Theodore Ts'odc256972005-01-26 13:20:12 -05001519Make sure e2fsprogs doesn't write garbage into the reserved portion of
1520large inodes.
1521
1522Make sure resize2fs releases the blocks belonging to the old inode
1523table blocks when moving the inode table. (Addresses Debian Bug:
1524#290894)
1525
1526Skip the r_resize_inode test if resize2fs is not compiled (due to
1527configure --disable-resizer)
1528
1529E2fsck now checks the summary filesystem accounting information, and
1530if any of the information is obviously wrong, it will force a full
1531filesystem check. (Addresses Debian Bug #291571)
1532
1533Fix e2fsck to not complain when the resize_inode feature is enabled,
1534s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1535the resize inode.
1536
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001537Fix e2fsck to note delete symlinks that contain an extended attribute
1538after the ext_attr feature flag has been cleared. (Addresses Red Hat
1539Bugzilla #146284).
1540
Theodore Ts'odc256972005-01-26 13:20:12 -05001541Add new utility program, copy_sparse.c, which is very useful
1542for dealing with large sparse files (such as e2image files).
1543
1544Add support for jnl_blocks[] for debugfs's set_super_value.
1545
1546Fix filefrag so that it works correctly with sparse files.
1547
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001548Filefrag -v will print first and last blocks.
1549
Theodore Ts'odc256972005-01-26 13:20:12 -05001550Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1551and dumpe2fs.
1552
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001553Add mke2fs support so that it can support filesystems larger than 4TB
1554automatically, by retrying with a 4k blocksize if the device size is
1555too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1556bug #1106631)
1557
Theodore Ts'odc256972005-01-26 13:20:12 -05001558Change blkid to test for NTFS first because Windows sometimes doesn't
1559clear enough of the parition to confuse the probing routines into
1560thinking the old filesystem type is still valid. (Addresses Debian
1561Bug #291990)
1562
Theodore Ts'o66fa0de2005-01-11 14:39:55 -05001563Add support for swap partition label and uuid's in the blkid library.
1564
Theodore Ts'odc256972005-01-26 13:20:12 -05001565Add support to the blkid library to recognize Oracle ASM volumes.
1566
1567Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001568not just the first one, and work more consistently when the blkid
1569cache file is not available or set to /dev/null. (Addresses Debian
1570Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -05001571
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001572Badblocks will now correctly display block numbers greater than
1573999,999,999 in its progress display.
1574
1575The tune2fs program will not allow the user from setting a ridiculous
1576number of reserved blocks which would cause e2fsck to assume the
1577superblock was corrupt. E2fsck's standards for what is a ridiculous
1578number of reserved block has also been relaxed to 50% of the blocks in
1579the filesystem.
1580
1581The blkid library will return vfat in preference to msdos, and ext3 in
1582preference to ext2 (if the journalling flag is set) so that mount will
1583do the right thing. (Addresses Debian bug #287455)
1584
1585Mke2fs will now use the -E option for extended options; the old -R
1586(raid options) option is still accepted for backwards compatibility.
1587Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1588
1589Mke2fs will now accept a size in megabytes, gigabytes, and other units
1590(via "32m" or "4g" on the command line) if the user finds this more
1591convenient than specifying a block count.
1592
1593Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1594cache conherency problem.
1595
1596Debugfs now supports a new command, set_inode_field, which allows a
1597user to manually set a specific inode field more conveniently, as well
1598as set entries in the indirect block map.
1599
1600Debugfs's set_super_value command has been enhanced so that the user
1601can set most superblock fields, including the date/time fields and
1602some of the more newsly added superblock fields.
1603
1604E2fsprogs programs now accept an offset to be passed to the file
1605specifiers, via the syntax: "/tmp/test.img?offset=1024".
1606
1607E2fsprogs programs will now accept blocksizes up to 65536; kernel
1608support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001609other architectures with page sizes greater than 4k. There are 2.6
1610kernel patches out there which enable this, but they are of this
1611writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001612
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05001613The e2image command now takes the -s option which will scramble
1614directory entries for raw image files.
1615
1616Fix a file descriptor leak in the filefrag program.
1617
1618Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1619present.
1620
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001621Fix bug in debugfs where kill_file would lead to errors when deleting
1622devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1623
1624Fix bug in the blkid library when detecting the ocfs1 filesystem
1625
1626Remove obsolete EVMS 1.x and a.out DLL support.
1627
1628E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -04001629
1630Fixed two potential ordering constraint problems in e2fsck which might
1631cause the filesystem to be corrupted if e2fsck is interrupted during a
1632(extremely narrow) race window. Thanks to Junfeng Yang from the
1633Stanford Metacompilation group for pointing this out.
1634
1635Fixed bug in e2fsck where it would not accurately detect whether or
1636not the system is running on adaptor if the ACPI device representing
1637the AC adapter didn't correspond to the what was used on IBM
1638Thinkpads.
1639
1640Change e2fsck to accept directories greater than 32MB.
1641
1642Fix e2fsck so that a checkinterval of zero disables a time-based check
1643of the filesystem.
1644
1645Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
1646to the PAGER environment variable. (Addresses Debian Bug #239547)
1647
1648Tune2fs will not mark rewrite the superblock if the feature bitmasks
1649are not modified.
1650
1651The debugfs program will set the filetype information when creating a
1652link.
1653
1654Add debugfs -d option to use a separate source of data blocks when
1655reading from an e2image file.
1656
1657Add e2image -I option which allows the e2image metadata to be
1658installed into a filesystem.
1659
1660Fixed bug in the badblocks program which caused "done" to always
1661appear in english even when a translation was available. (Addresses
1662Debian Bug #252836)
1663
1664The blkid program has a new option -o which controls the output format
1665of the blkid program; this is makes blkid more convenient to use in
1666shell scripts.
1667
1668Fix a minor bug in uuid library, which was not using the full 14 bits
1669of clock sequence when generating UUID's.
1670
1671Fix a Y8.8888K problem in the uuid library.
1672
1673Logsave now creates a new session id for itself to avoid getting
1674killed by init whan transitioning between init levels.
1675
1676Change the licensing of the UUID library to be the 3-clause BSD-style
1677license; this allows Apple to use the uuid library in Darwin.
1678
1679Add ocfs and ocfs2 probe support into the blkid library.
1680
1681Fix a memory and file descriptor leak in the blkid library.
1682
1683The blkid library will revalidate the device if the system time is
1684earlier than last verification time of the device, since that
1685indicates that the system time is probably nottrustworthy.
1686
1687The blkid library will override the default location of the blkid.tab
1688file by the BLKID_FILE environment variable, if it is available.
1689
1690Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
1691
1692Add various portability fixes for lame new versions of glibc, Darwin
1693and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001694Bugs #239934, #264630, #269044, #255589, #289133)
1695
1696Add support for Windows 9x/NT under Cygwin.
Theodore Ts'o48301122004-09-19 08:23:41 -04001697
1698Updated and clarified various man pages. (Addresses Debian Bugs #236383,

Theodore Ts'o48301122004-09-19 08:23:41 -04001700
1701Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
1702
1703Update the rpm spec files so that it works better with Fedora core 2
1704and RH9.
1705
1706Fixed various Debian packaging issues (see debian/changelog). In
1707particular, fixed the Debian initrd scripts. (#241183, #248050,

Theodore Ts'o48301122004-09-19 08:23:41 -04001715
1716The uuid library now has new functions uuid_unparse_upper() and
1717uuid_unparse_lower() which forces the case of the hex digits to be
1718upper case, or lower case.
1719
1720The build process has been speeded up by enhancing the subst program
1721to update the modtime on the generated files even when the generated
1722file hasn't changed.
1723
1724The uuid library now uses C99 stdint.h types instead of custom types.
1725
1726Updated config.guess and config.sub with newer versions from the FSF.
1727
1728Removed out of date .cvsignore files from the source distribution.
1729
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001730The ext2fs_unlink() function will return an error if both the name and
1731inode number are unspecified, to avoid doing something surprising
1732(such as unconditionally deleting the first directory entry).
1733Directory entries are now deleted by coalescing them with the previous
1734directory entry if possible, to avoid directory fragmentation. This
1735is not an issue with the e2fsprogs suite, but may be a problem for
1736some of the users of libext2fs, such as e2tools.
1737
1738Add support for version numbers of the form "1.36-rc1".
1739
Theodore Ts'o48301122004-09-19 08:23:41 -04001740Fix build of mke2fs.static.
1741
Theodore Ts'odc256972005-01-26 13:20:12 -05001742Add basic ext2fs library support for large (EA in inode) inodes.
1743
Theodore Ts'o48301122004-09-19 08:23:41 -04001744The test_io mechanism can now abort after n reads or writes to a
1745particular block. The block is specified by TEST_IO_BLOCK environment
1746variable, and the read/write count by the TEST_IO_READ_ABORT and
1747TEST_IO_WRITE_ABORT environment variables. The block data is now only
1748dumped if the 0x10 bit is set in TEST_IO_FLAGS.
1749
1750UUID_DEFINE() in the uuid library now creates a static variable, with
1751__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
1752be used in header files.
1753
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001754Add support for the install-strip and install-shlibs-strip targets, as
1755suggested by the GNU coding guielines. "make install" no longer
1756strips the binaries which are installed.
1757
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001758Remove support for the --enable-old-bitops configure option which was
1759only for very old sparc systems.
1760
1761Remove support for --enable-clear-htree; this was only needed during
1762the early development of the htree patch.
1763
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001764Use Linux-kernel-style makefile output so it is easier to see compiler
1765warnings.
1766
1767Update gettext files to version 0.14.1.
1768
1769Update to use autoconf 2.5x.
1770
1771Improved support for compiling e2fsprogs under dietlibc.
1772
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05001773Make e2fsprogs portable to Solaris and FreeBSD systems.
1774
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001775Add blkid_verify(), blkid_get_library_version(), and
1776blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -05001777
1778Add pkg-config files for e2fsprogs's libraries.
1779
1780Fix "make uninstall" to so that it removes everything that is installed.
1781
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001782Add a configure --enable-maintainer-mode option which enables the
1783makefile rules to rebuild the configure script from configure.in, and
1784to reubuild the .gmo files in po directory.
1785
1786Drop the sparc assembly bitwise operations; it's less efficient
1787than the GCC 3.4 compile code and triggers compiler warnings on
1788sparc64. Thanks to Matthias Andree for his analysis and suggestions.

Theodore Ts'ob70b1162004-02-28 10:52:35 -05001792E2fsprogs 1.35 (February 28, 2004)
1793==================================
1794
Theodore Ts'o48301122004-09-19 08:23:41 -04001795E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001796preserves the existing badblocks list.
1797
Theodore Ts'o48301122004-09-19 08:23:41 -04001798Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001799
1800E2fsprogs will now deal correctly with symlinks that contain
1801extended attribute information, which can be created using SE Linux.
1802(Addresses Debian Bug #232328)
1803
1804Remove a double longjump into an invalid stack frame bug in e2fsck.
1805(This was during an abort sequence, which normally worked on Linux and
1806caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001807
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001808Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
1809(the NLS library will replace "" with the .po header information).
1810
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001811Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
1812dump due to a division by zero error. (Addresses Debian bug #207082)
1813
Theodore Ts'o151a7162003-12-26 14:04:33 -05001814Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
1815when reconnecting a directory requires creating a lost+found
1816directory. (Addresses Debian bug #219640).
1817
1818Fixed a bug where e2fsck would bomb out if a journal needed to be
1819replayed when using an alternate superblock.
1820
Theodore Ts'o48301122004-09-19 08:23:41 -04001821E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001822if the laptop is running on battery. The next time fsck runs while
1823the system is on the AC mains, or after the grace period is exceeded,
1824the filesystem will be checked. (Addresses Debian bug #205177)
1825
1826E2fsck will inform the user when there are 5 or fewer mounts before a
1827filesystem check will be forced. (Addresses Debian bug #157194)
1828
1829Fix e2fsck's handling of corrupted indirect blocks in the bad block.
1830We now correctly handle the case where there is an overlap between a
1831block group descriptor or a superblock and a bad block indirect block.
1832In the case where the indirect block is corrupted, we now suggest
1833"e2fsck -c".
1834
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001835Fix byte swap bugs in e2fsck that caused the journal backup location
1836in the superblock and symlinks created by SE Linux to be cleared
1837by e2fsck on big-endian machines. (Addresses Debian bug #228723)
1838
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001839E2fsck -c now replaces the current list of bad blocks with the ones
1840found by badblocks.
1841
1842Fix bugs in e2fsck and tune2fs which could cause a core dump if a
1843non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
1844
1845Fix a potential bug in e2fsck which could cause it to core dump when
1846trying to print the location of the backup superblock.
1847
1848Protect against a potential core dump in e2fsck when printing a
1849message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001850
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001851Add support for backing up the journal inode location in the
1852superblock. E2fsck will automatically save the journal information in
1853the superblock if it is not there already, and will use it if the
1854journal inode appears to be corrupted. ext2fs_add_journal_inode()
1855will also save the backup information, so that new filesystems created
1856by mke2fs and filesystems that have journals added via tune2fs will
1857also have journal location written to the superblock as well.
1858Debugfs's logdump command has been enhanced so that it can use the
1859journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001860
1861E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001862
1863Shrink the size of the e2fsck executable by moving some initialized
1864variables to the BSS segment.
1865
1866E2fsck will avoid printing the ^A and ^B characters which bracket the
1867progress bar when stdout and stdin are a tty device instead of a pipe
1868to another program. (Addresses Debian bug #204137)
1869
Theodore Ts'o151a7162003-12-26 14:04:33 -05001870Debugfs's mkdir command will automatically expand the directory if
1871necessary. (Addresses Debian Bug: #217892)
1872
1873Fixed a bug in debugfs so that copying a file from /dev/null uses the
1874correct mode bits. (Addresses Debian Bug: #217456)
1875
1876If the environment variables DEBUFS_PAGER and PAGER are not set,
1877debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -05001878/usr/bin/pager, and then falling back to 'more' and 'less'.

1880
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001881Debugfs will now support 2.6 device numbers where the major or minor
1882number may be larger than 255. (Addresses Sourceforge bug #865289)
1883
Theodore Ts'o48301122004-09-19 08:23:41 -04001884Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
1885

Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001889Fix regression tests so they work correctly when e2fsprogs is compiled
1890with configure --disable-htree.
1891
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001892Fix bug in uuid library when there is no network card and the library
1893is generating a time-based uuid. The random MAC address was not
1894correctly generated to be a multicast address.
1895
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001896Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -04001897around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001898
1899Fix bug in badblocks when using O_DIRECT; we need to make sure that
1900we're reading from an offset which is page aligned. For read-only and
1901read-write tests, we try to recover after an error so that we can
1902continue reading on page-aligned boundaries. (Addresses Debian Bug

1915Programmer's notes:
1916-------------------
1917
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001918Fixed a build problem so that e2fsprogs would compile with the
1919--enable-profile option to configure selected. (Addresses Sourceforge
1920bug #811408)
1921
1922Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
1923Bugzilla Bug #112448)
1924
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001925Centralize code which calculates the location of the superblock
1926and block group descriptors so that it is in a single library routine.
1927
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001928Added two new functions, ext2fs_file_open2() and
1929ext2fs_inode_io_intern2() which take a pointer to an inode structure.
1930
1931Fix compile_et to output the correct prototype for
1932initialize_xxx_err_table_r() in the header file. (Addresses Debian
1933bug #204332)
1934
1935In the lib/et makefile, make sure com_err.info is deleted on "make clean".
1936
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001937Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
1938present. This is for when we try stuffing an int into void * pointer.
1939
1940Fix type-punning which can cause gcc 3.x to miscompile code by getting
1941confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
1942and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
1943**'. The EVMS code uses an ugly union approach since we don't want to
1944modify the EVMS interfaces.
1945
1946Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
1947aid build process on systems can use invoke GNU make as "gmake".
1948
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001949Added regression testing for mke2fs.
1950
1951Fixed gcc -Wall nitpicks.
1952
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001953Fixed various compiler warnings.
1954
1955Add portability fixes for FreeBSD and for using fsctl under Darwin to
1956support ext2 ioctl's.
1957

Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001959E2fsprogs 1.34 (July 25, 2003)
1960===============================
1961
1962Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
1963a tight loop while waiting for a child fsck to exit in some cases.
1964This burns CPU times which slows down the low-level filesystem check.
1965
1966Added code to mke2fs to assure that the default block size for a
1967filesystem is at least as big as the sector size of the device, if it
1968can be determined.
1969
1970Changed mke2fs and resize2fs to round the default size of a filesystem
1971to be an even multiple of the VM pagesize in order to avoid a Linux
1972kernel bug introduced when the storage of the buffer cache was moved
1973into the page cache.
1974
1975Mke2fs will warn the user when creating a filesystem with journaling
1976and a blocksize greater than 4096. (Addresses Debian bug #193773)
1977
1978Fixed a bug in resize2fs which caused it to fail on filesystems with a
1979non-empty bad block list. Resize2fs now discards any blocks on the
1980badblock list which are no longer part of the filesystem as the result
1981of a filesystem shrink. (Note: this means that shrinking and then
1982enlarging a filesystem is no longer a reversible operation;
1983information about bad blocks in the part of the filesystem which is to
1984be chopped off will be lost.)
1985
1986Changed resize2fs so the user can use prefixes to specify the units of
1987the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
1988and to make the error and informational messages explicitly display
1989the blocksize used by the filesystem, in order to avoid confusion.
1990(Addresses Debian bug: #189814)
1991
1992Added a new debugfs command, dump_unused, which dumps the contents of
1993all unused blocks to stdout. (Useful as an emergency try-to-find
1994deleted data command.)
1995
1996Added a new debugfs command, imap, which prints the location of a
1997specified inode in the inode table.
1998
1999Fixed a bug in the badblocks program which caused it to use one bit of
2000randomness in its non-destructive read/write test, instead of using a
2001full 8 bits of randomness.
2002
2003Added a new option (-t) to badblocks, which allows the user to control
2004the test pattern(s) used when checking a disk.
2005
2006The blkid probe function now more correctly detects UDF filesystems.
2007
2008Fixed a bug in the blkid library which caused it to not update its
2009cache if a filesystem changes from having a label to not having a
2010label.
2011
2012Fixed a bug in the blkid library wihch could avoid an infinite loop
2013in blkid_find_dev_with_tag() if /proc is not mounted and there the
2014/etc/blkid.tab file has not yet been created.
2015
2016Fixed the badblocks program so that the destructive read/write test
2017honors the -c option, and to use O_DIRECT when possible to avoid
2018thrashing the system block buffer cache.
2019
2020Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -04002021 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04002022 - Removed testing NYC translation
2023 - Fixed NLS support for message abbrevations in e2fsck
2024 - Remove de-utf.po, since we shouldn't have two versions using different
2025 charset encodings.
2026 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
2027 simplify the statistics reporting in e2fsck.
2028
2029Changed configure.in so that its defaults for *BSD systems no longer
2030build an fsck wrapper, and not to install in /usr/local by default.
2031
2032Fixed some minor spelling errors/typo's in e2fsck and the configure
2033script.
2034
2035Fixed various Debian packaging issues (see debian/changelog).
2036
2037Updated and clarified man pages. (Addresses Debian Bug #195616)
2038
2039Programmer's notes:
2040-------------------
2041
2042Fix gcc -Wall nitpicks.
2043
2044Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
2045NLS support by default. (Added partial workaround for gettext/Darwin
2046incompatibility problems.)
2047
2048Added full MIT KRB5 and Himdall compaibility support to the com_err
2049library and the compile_et program. (Addresses Debian bug #191900)
2050
2051Added the blkid_known_fstype() function to the blkid library, which
2052returns true if it is passed a filesystem type which is recognized by
2053the blkid probing functions.
2054
2055Improved the documentation for the blkid library.
2056
2057Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
2058returns the hardware sector size of a device, if it is available.
2059
2060Added a dependency in the blkid library's .so file to the uuid
2061library, since the former uses the latter. (Addresses Debian bug
2062#194094)
2063
2064Added --with-diet-libc and --disable-evms to the configure script.
2065
2066Fixed a minor memory leak in the badblocks program.
2067
2068Fixed a portability problem in tune2fs --- not all systems have strptime().
2069
2070Fixed a portability problem in debugfs with the use of getopt() more
2071than once. Old-style BSD, new-style BSD, and Linux C libraries all do
2072things differently.
2073
2074Add support Windows support to ext2fs_get_device_size().
2075
2076Added (normally disabled) debugging code to the Unix I/O manager which
2077causes it to disable all userspace caching if the NO_IO_CACHE is
2078defined.
2079
2080Changed the test I/O manager so it can always be linked into e2fsck,
2081mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
2082configure script. The test I/O manager will only print any debugging
2083information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
2084variables are set, which specifies which I/O operations are logged and
2085a block number to watch, respectively. The log messages are sent to
2086stderr by default, unless a filename is specified via the
2087TEST_IO_LOGFILE environment variable.

Theodore Ts'o71df0dc2003-04-21 16:17:09 -04002090E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04002091===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -05002092
Theodore Ts'oba142c12003-04-16 00:59:59 -04002093Added a new utility program, logsave, which captures the output of a
2094command in a log file, even if the containing directory hasn't been
2095mounted yet (in which case the it saves the output in memory until it
2096can write out the logfile). This is useful for capturing the
2097output of fsck during the boot sequence.
2098
2099Fixed some portability problems that were causing problems under
2100the Cygwin32 environment.
2101
2102Mke2fs now interprets a negative number to the -b option as a minimum
2103block size.
2104
2105Fixed a bug in mke2fs which was incorrectly checking the argument to
2106the -g option if the default block size was used. (Addresses Debian
2107bug #188319)
2108
2109Fsck now explicitly ignores tmpfs and devpts, and it will complain if
2110it can not find filesystem checkers for jfs, reseirfs, and xfs.
2111
2112E2fsck now updates the global free block and inode counters from the
2113block group specific counters quietly. This is needed for an
2114experimental patch which eliminates locking the entire filesystem when
2115allocating blocks or inodes; if the filesystem is not unmounted
2116cleanly, the global counts may not be accurate.
2117
2118Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
21192.0 is not yet supported; this only pulled in the bug fixes: fixed
2120possible hangs caused by bugs in calling waitpid, and not setting the
2121pipe to non-blocking mode; also fixed a file descriptor leak; made
2122sure all functions call log entry/exit functions.)
2123
2124Badblocks now flushes its output file as bad blocks are discovered.
2125
2126The uuid library is now more paranoid about assuming the correctness
2127of the /dev/random device; it mixes in a stream of bytes from
2128random/srandom, just in case.
2129
Theodore Ts'o39d38b02003-03-30 23:45:02 -05002130Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04002131maintainer of e2fsprogs. Other various Debian-specific packaging
2132cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05002133
2134Move the source tarball generation functions from the top-level
2135makefile to the util/gen-tarball script.
2136
2137Updated the Turkish .po translation file.
2138
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002139Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05002140it more compatible with com_err libraries from those distributions.
2141
2142Changed dumpe2fs to always display the superblock fields relating to
2143the journalling and/or directory indexing feature even if those
2144features are not enabled.
2145
Theodore Ts'o508d7f32003-03-16 20:41:04 -05002146Updated and clarify copyright statement vis-a-vis alpha releases of
2147e2fsprogs.
2148
2149The ss library will now try to dynamically link to the readline
2150library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04002151the debugfs program now has line editing and history features. The
2152SS_READLINE_PATH environment variable is used to find a readline or
2153readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002154
Theodore Ts'oe5dced72003-03-15 04:28:17 -05002155E2fsck now finds most duplicate filenames (all when rebuilding all
2156directories via the -D option) and offers to delete or rename
2157duplicate filenames/directory entries. (Addresses Debian Bug #176814).
2158
2159Fix bug in e2image. When writing out a raw image file, include data
2160blocks from symlinks that do not store the symlink within the inode.
2161
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002162Fix bug in resize2fs which incorrectly moved the block and inode
2163bitmaps for sparse superblock filesystems and incorrectly marked
2164blocks as in use. (Addresses Debian bug #174766)
2165
2166Added a new shared library, the blkid library, which efficiently
2167allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
2168and UUID filesystem specifiers without needing to search all of the
2169devices in the system. Instead, the device is looked up in a cache
2170file, and then verified to make sure the blkid cache is correct.
2171
2172Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
2173the device name, using the blkid library. (Addresses Debian bugs
2174#166048, #179671)
2175
2176Fsck now supports backslash escapes in /etc/fstab so that \040 can be
2177used for spaces in device labels.
2178
2179Removed 32-bit limitations for debugfs's dump command.
2180
2181If the user specifies a large number of inodes, Mke2fs will
2182automatically adjust the number of blocks per group to find a valid
2183set of filesystem parameters.
2184
2185Add workaround to detect broken MD devices where when some of the
2186underlying devices are marked read-only, writes to the MD device are
2187silently dropped. E2fsck will detect if there is an attempt to run
2188the journal twice, and abort with an error if this is the case.
2189(Addresses IBM Bugzilla bug #1226)
2190
2191E2fsck will print an error if more than one of the -p/-a, -n or -y
2192options are specified.
2193
2194E2fsck will fix HTREE corruptions in preen mode, without stopping the
2195boot process. This is needed because the 2.4 ext2 filesystem
2196accidentally had the INDEX_FL backwards compatibility code removed.
2197
2198Mke2fs no longer creates filesystems with the dir_index flag set by
2199default; the user has to specifically request it.
2200
2201Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04002202#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002203
Theodore Ts'o508d7f32003-03-16 20:41:04 -05002204Created man page for the mk_cmds program (from the libss library).
2205
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002206Programmer's notes:
2207-------------------
2208
2209Fix various gcc -Wall nits.
2210
2211Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05002212successfully under Solaris and Apple/Darwin.
2213
2214Fixed a Makefile dependency to allow building e2fsprogs using parallel
2215make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002216
2217Changes to create a subset distribution which consists only of the
2218et, ss, uuid, and blkid libraries. The configure script and top-level
2219makefile were changed to support working with a subset distribution.
2220
Theodore Ts'oba142c12003-04-16 00:59:59 -04002221Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
2222actually used, and might people who are looking for
2223EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
2224
Theodore Ts'o508d7f32003-03-16 20:41:04 -05002225Updated debian files to fix a number of Lintian warnings.
2226
2227Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002228
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04002229Removed unnecessary libraries from being linked into the fsck, lsattr,
2230chattr, and blkid executables.
2231
Theodore Ts'o38513012002-11-09 15:00:56 -05002232E2fsprogs 1.32 (Nomvember 9, 2002)
2233==================================
2234
2235Fixed a bug in the Unix I/O routines which caused needless writebacks
2236of clean blocks from the unix_io cache (they were erroneously marked
2237as being dirty, so they were getting written back to disk before
2238getting evicted from the disk cache). This was harmless, but it
2239significantly slowed down e2fsck.
2240
2241Made some other minor optimizations to the Unix I/O routines to save a
2242small amount of CPU time.
2243
2244Updated internationalization files.
2245
Theodore Ts'o3809bf12003-03-07 01:09:57 -05002246
Theodore Ts'oae65b292002-11-08 20:08:48 -05002247E2fsprogs 1.31 (Nomvember 8, 2002)
2248==================================
2249
2250Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
2251compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
2252handling for child process that die unexpectly. Add a hack to force
2253mkfs to create filesystems that won't cause problems with hardware
2254that has 2k or 4k minimum blocksize requirements. Read from child
2255processes in non-blocking mode, so that the GUI continues to update.
2256
2257Fix e2fsck so that it returns the appropriate exit code when the root
2258filesystem has been changed, so that system's rc scripts will be told that
2259the system needs to be rebooted.
2260
2261Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
2262was set, some of the descriptor blocks that should have been written
2263out were getting skipped.
2264
2265Changed e2fsck to force out changes to the backup copies of the
2266superblock and block group descriptors when important changes are made
2267to those data structures.
2268
2269Fix a bug where e2fsck could erroneously mark a filesystem as being
2270clean if a check of dirty filesystem is interrupted with a ^C. (Bug
2271introduced in e2fsprogs 1.28.)
2272
2273If journal debuging is enabled using --enable-jbd-debug, the debugging
2274level is now set via the E2FSCK_JBD_DEBUG environment variable.
2275
2276If byteswapping support is disabled using configure --disable-swapfs,
2277skip the tests which depend on byte-swapping, so that "make check"
2278won't bomb out.
2279
2280Lshattr will now display the indexed directory flag. Also, some of
2281the more esoteric compression flags are supressed unless compression
2282support has been enabled.
2283
2284Update man pages.
2285
2286
Theodore Ts'o5d823a42002-11-01 02:13:53 -05002287E2fsprogs 1.30 (October 31, 2002)
2288=================================
2289
2290When resizing a filesystem, and inodes need to moved, resize2fs will
2291update the inode's ctime field, and the mtime field of the containing
2292directories, so that incremental backups using dump/restore will work
2293correctly.
2294
2295In order to avoid spurious errors, e2fsck wil check the last
2296superblock write time to determine whether or not it can safely use
2297the LOW_DTIME checks to determine if there are inodes on the orphan
2298inode linked list that had somehow gotten disconnected. (Addresses
2299Sourceforge bug #620980)
2300
2301Partition in /proc/partitions that being with the string "lvm" are
2302considered real partitions even if they do not end with a number.
2303
2304Fixed a bug in the the uuid generation function, where if /dev/urandom
2305is not present, but /dev/random is, and there isn't sufficient
2306entropy, the get_random_byte function could spin a loop forever.
2307
2308E2fsck, mke2fs, etc. will now reliably notice when image files are
2309mounted using the loopback interface. (Addresses Sourceforge bug
2310#619119)
2311
2312When flushing buffers (as is done by badblocks, for example) check to
2313see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
2314FDFLUSH ioctl which causes the MD device driver which causes confusing
2315syslog messages about obselete ioctl messages. (Addresses Sourceforge
2316bug #545832).
2317
2318Debugfs's write command now checks to see if the destination filename
2319exists before creating it. (Addresses Sourceforge bug #478195.)
2320
2321When installing man pages, search for compressed man pages using all
2322commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
2323
2324Fixed a bug in fsck where multiple filesystems specified on the
2325command were not being checked in parallel due to a logic bug
2326introduced to support the FSCK_MAX_INST environment variable.
2327
2328We have added a new superblock field, s_mkfs_time, which indicates
2329when a filesystem was created. It is set via mke2fs, and printed out
2330by dumpe2fs, but is not actually touched by the kernel.
2331
2332Dumpe2fs has been made more robust by not aborting if there is an
2333error reading the block/inode bitmaps; instead it will still print out
2334the location of the block/inode bitmaps and inode table.
2335
2336Add support for the an alternative block group descriptor layout which
2337allows for on-line resizing without needing to prepare the filesystem
2338in advance. (This is the incomat feature flag meta_bg.)
2339
2340Add support for storing default mount options in the superblock, so
2341that the filesystem can be mounted with specific mount options without
2342needing to specify them on the mount command line or in the /etc/fstab
2343file.
2344
2345Add support for a new inode flag, which is to be used for indicating
2346the top of directory hierarchies for the Orlov block allocator.
2347
2348Fix e2fsck so that if it creates the lost+found directory, it does so
2349with the more apporpriate permissions of 0700. Also change
2350mklost+found so that it also creates the directory 0700.
2351
2352Fixed format bug in e2fsck if NLS is in use.
2353
2354Add a German translation for e2fsprogs's NLS support.
2355
2356Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
2357the beginning of the inode table. This won't matter much, since if
2358there is a bad block at the beginning of the inode table, the root
2359directory won't be available. But at least e2fsck won't crash in this
2360case.
2361
2362Fixed endian problems in the htree code for e2fsck and debugfs.
2363
2364When byte-swapping a filesystem on a PPC architecture, byte-swap the
2365bitmaps since the historical big-endian ext2 variant had byte-swapped
2366bitmaps, and the ext2fs library assumes this. This fixes the
2367regression test suite on PPC machines.
2368
2369Fix e2image so that it handles a bad block in the inode table
2370appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04002371
2372E2fsck now uses a more sophisticated algorithm to salvage corrupted
2373directories that recovers more information in the corrupted directory
2374block.
2375
2376E2fsck now performs additional consistency checks on indexed (HTREE)
2377directories.
2378
2379Fix bug where efsck might get confused about whether a completely
2380empty directory block is an empty leaf block or an interior htree
2381node. This could cause e2fsck to get confused into think that a valid
2382indexed directory was corrupted.
2383
2384E2fsck no longer creates an empty directory entry at the end of a
2385directory block when optimizing a directory. This would cause some
2386earlier versions of the dxdir kernel code to corrupt the directory
2387when attempting to split a node containing an empty directory entry.
2388
2389E2fsck could sometimes in rare circumstances leave the indexed flag
2390set after a small directory was optimized by compressing it instead of
2391indexing it. (This should never happen in real life, since
2392directories that small wouldn't have been indexed, but better safe
2393than sorry.)
2394
2395E2fsck now only updates the master superblock in all cases. This
2396slightly shortens its run time.
2397
2398Ext2ed can deal with directory entries of length 0; previously it
2399would get stuck in an infinite loop.
2400
2401Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
2402specifiers. (Sourceforge patch #613447)
2403
2404Badblocks will now work correctly on read-only devices such as
2405CD-ROM's. (Sourceforge patch #600451)
2406
Theodore Ts'o5d823a42002-11-01 02:13:53 -05002407Updated and clarified man pages. (Addresses Debian bug #167108)
Theodore Ts'od5e78102002-09-30 11:33:36 -04002408
2409
Theodore Ts'oc6633052002-09-24 01:26:50 -04002410E2fsprogs 1.29 (September 24, 2002)
2411===================================
2412
2413Fixed a bug in e2fsck which could corrupt a directory when optimizing
2414it (via the -D option) or rebuiliding the hash tree index with a 1 in
2415512 probability, due to a fence post error.
2416
2417Fixed a bug in the LVM support code which caused LABEL='xxx' not to
2418work correctly.
2419
2420Mke2fs now enables the directory indexing flag by default. (Since
2421this is a compatible feature flag, it's safe to do so.)
2422
2423Tune2fs will support setting the directory indexing feature flag. It
2424will automatically set up the default hash algorithm and hash seed
2425fields in the superblock.
2426
2427If the bone-headed user enters the root filesystem twice in
2428/etc/fstab, the -R option which skips the root filesystem will skip
2429all of them. (Addresses Debian bug #159423). Note! This is not a
2430precedent for dealing intelligently with any other kind of doubled
2431entry in /etc/fstab!
2432
2433
2434Programmer's notes:
2435-------------------
2436
2437Removed perror declaration in lib/et/internal.h. All modern systems
2438can be expected to define perror() these days. Besides, the lib/et
2439code wasn't using perror at all anyway. :-)
2440
2441
Theodore Ts'ob7bad612002-08-31 03:00:33 -04002442E2fsprogs 1.28 (August 31, 2002)
2443================================
2444
2445Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2446for setting the htree flag is not included yet, although it can be
2447manually turned on via the debugfs program.
2448
2449Clarified e2fsck error message which is printed when it cannot find
2450sufficient contiguous block when relcating filesystem metadata.
2451
2452Added support for building an EVMS plugin module for ext2/3. This
2453module is substantially the same as the EVMS module shipping with EVMS
24541.1, with one or two bugfixes. E2fsprogs can also build this plugin
2455for use with EVMS 1.0 (which did not include the ext2 plugin module),
2456if the configure --enable-old-evms flag is given.
2457
2458Fsck will search through EVMS volumes when trying to resolve
2459filesystem specifications such as LABEL=xxx or UUID=xxx.
2460
2461Added a new utility program, /sbin/findfs, which will return
2462filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2463the device name.
2464
2465Update and clarified various man pages. (addresses Debian Bug #145044,
2466#146437, #131350, #151990, #144621, #141938)
2467
2468If there are no filesystems specified on fsck's command line, fsck now
2469treat that as if the -As options were given. Previously it would
2470simply do nothing. (Addresses Debian Bug #153102)
2471
2472Mke2fs no longer treats a failure to be able to clear the MD signature
2473at the end of the filesystem as a fatal error. (Addresses Debian Bug
2474#155007)
2475
2476The e2p library functions (which are used by lsattr and chattr) now
2477double check to make sure the file is a regular file or directory
2478before attempting to use the ext2 ioctls. Some device drivers
2479unfortunately respond to the ext2 ioctl's with unknown behaviour.
2480(Addresses Debian Bug #152029).
2481
2482The extended attribute handling has been updated to correspond with
2483the latest V2 bestbits ACL code.
2484
2485Fixed bug in e2fsck which caused it to not clear the dtime field when
2486processing truncated inodes on the orphan list. This could cause data
2487loss(!) if a filesystem is rebooted before a truncate has been
2488committed.
2489
2490E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2491algorithms. This makes e2fsck much faster in the case of severely
2492corrupted filesystems where a large number of blocks are claimed by a
2493large number of inodes. (Thanks to the 2.5 IDE device driver for
2494inspiring this work.)
2495
2496Resize2fs has been significantly sped up when shrinking and expanding
2497a filesystem by a very small number of blocks (for example, when EVMS
2498is converting a partition to be an EVMS legacy volume).
2499
2500Added a new option to e2fsck, -D, which will optimize or compress all
2501of the directories in the filesystem.
2502
2503E2fsck now catches SIGINT and SIGTERM to make sure it will can
2504properly clean up and only exit at safe points. Fsck will pass
2505SIGINT/SIGTERM to its child processes, and wait until they have all
2506exited before it exits.
2507
2508The uuid parsing code in the uuid library now properly complains when
2509an illegally formated uuid is presented to it. (Addresses Debian bug
2510#152891)
2511
2512Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2513and 2.4.17, since the workaround can cause problems when using a 2.4
2514kernel with an old version of glibc built with the 2.2 headers.
2515
2516Fixed a bug in mke2fs where it wasn't properly clearing the initial
2517superblock used by other filesystems. (Addresses Debian bug #147256.)
2518
2519Added support for the synchronous directory feature written by Andrew
2520Morton.
2521
2522The debugfs program can delete directories using the rmdir command.
2523
2524Add support for 8k and 16k filesystems (for systems with page sizes
2525that are greater or equal to 8k or 16k, respectively). Note that
2526these filesystems can not be mounted on x86 systems, or other systems
2527with only 4k page sizes, due to limitations in the current Linux VM
2528code.
2529
2530Resize2fs requires that the filesystem state be valid and have no
2531errors; otherwise, e2fsck -f must be run first. (Previously it simply
2532required that the last fsck time be greater than the last mount time.)
2533
2534Configure now defaults the man pages directory to /usr/share/man on
2535Linux systems.
2536
2537E2fsck now offers to truncate inodes which contain too many blocks (so
2538that i_blocks would overflow. Also fixed handling of large sparse
2539files.
2540
2541E2fsck now more completely checks for symlink validity, including
2542requiring NULL termination and length checks.
2543
2544E2fsck will offer to try forcing a disk write to remap a bad block
2545after finding a read error when reading a filesystem metadata block.
2546
2547Fixed a bug in debugfs which caused the -b and -s options to crash
2548debugfs, as well as breaking the testb, setb, and clearb functions.
2549
2550Added a bmap command to debugfs which calculates the logical to
2551physical block mapping for a particular inode.
2552
2553Fixed a bug in code which checked to see if a device was mounted which
2554sometimes (rarely) failed in the case of a plain file.
2555
2556Fixed a bug in resize2fs where when it reported an error, it would
2557print a message erroneously indicating that the filesystem had been
2558resized before it aborted.
2559
2560When resizing a plain file which is smaller than the requested size,
2561resize2fs will attempt to extended the file so that programs like
2562e2fsck will not complain that the file is too small.
2563
2564Resize2fs will print the actual new size of the filesystem when it is
2565finished resizing.
2566
2567Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2568information on big-endian systems.
2569
2570
2571Programmer's notes:
2572-------------------
2573
2574Fixed collisions with C++ reserved words.
2575
2576Added portability fixes for building e2fsprogs on the HURD and AIX.
2577
2578Added the ext2ed program for creation of test cases. (ext2ed has many
2579limitations and bugs which make it unsuitable for production use.)
2580
2581The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2582flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2583name_len field is byte swampped on big-endian machines, since in the
2584V2 structure, name_len is a char field which is doesn't need to be
2585byte swapped --- except if an old-style kernel had byte-swapped the
2586name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -05002589E2fsprogs 1.27 (March 8, 2002)
2590==============================
2591
2592The warning messages for mke2fs now go to standard error.
2593
2594Fixed to make sure "make check" runs all of the test programs with
2595LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2596
2597The mke2fs program checks the boot sector for the BSD disk label, and
2598avoids erasing it if it is there.
2599
2600Fixed a bug in e2fsck which caused it to core dump if the journal
2601inode was missing when it was supposed to be there.
2602
2603E2fsck now prints ranges in pass 5 when printing deltas for the block
2604and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002605
2606Debugfs's "ls -l" command now will print out the file type information
2607in the directory entry.
2608
2609Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2610mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2611
2612Debugfs can now examine the experimental directory indexing
2613information.
2614
Theodore Ts'oa471ac52002-03-05 03:37:06 -05002615Fixed bug in debugfs which caused it to core dump if modify_inode is
2616called without an open filesystem.
2617
2618The debugfs lsdel command now runs its output through a pager first.
2619
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002620When installing manual pages, remove the compressed manual pages first.
2621
2622Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2623
2624Fix the 2.4 resource limitation workaround introduced in 1.26 which
2625actually broke things on mips32, sparc32, and Alpha platforms.
2626
Theodore Ts'oa471ac52002-03-05 03:37:06 -05002627Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2628(which is required by the newer libintl libraries).
2629
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002630Programmer's notes:
2631-------------------
2632
Theodore Ts'oa8e77242002-03-08 03:12:14 -05002633Fixed various gcc -Wall complaints.
2634
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002635Fixed a few memory leaks in the e2fsck journaling code, and in the
2636ismounted code checking for a swap device.
2637
2638Add new inode I/O abstraction interface which exports an inode as
2639an I/O object.
2640
2641Exported ext2_file_flush as a public interface.
2642
2643In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
2644
2645Lots of small random portability fixes to make e2fsprogs build under
2646AIX --- even without the 5L compatibility toolkit, and even using the
2647uber-crippled AIX native C compiler.
2648
2649
Theodore Ts'o06987392002-02-03 01:36:54 -05002650E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002651=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002652
Theodore Ts'o446314f2001-12-24 15:22:27 -05002653Dumpe2fs will keep going now if the bad block inode can't be read.
2654(Previously it stopped with a fatal error.)
2655
2656E2fsck will now give an opportunity to run the journal even if the
2657recovery flag is not set. This is the default behaviour if e2fsck is
2658using a backup superblock, since the needs_recovery flag will never be
2659set in the backup superblock copies.
2660
2661E2fsck now automatically finds the backup superblock/group descriptors
2662even when the primary superblock is completely destroyed for 2k and 4k
2663filesystems. (Previously it just guessed/assumed that we were dealing
2664with a 1k filesystem in that case, and users had to manually specify
2665the backup superblock number.)
2666
2667Fixed a bug in e2fsck where it dereferences a null pointer when there
2668is a problem opening a filesystem in preen mode.
2669
2670E2fsck now handles external journals correctly; previously it trashed
2671the external journal device if the journal needed to be replayed.
2672
2673Work around ulimit incompatibility problem caused by recent 2.4
2674kernels; the unix IO module will automatically try to set any resource
2675limits to be infinite on startup.
2676
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002677Fixed a bug in e2fsck where it wasn't allocating a new block or inode
2678bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04002679 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002680
2681E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
2682clearing the new V2 fields if they do not make sense or if the ext3
2683superblock is version 1 superblock.
2684
2685E2fsck will automatically relocate the ext3 journal from a visible
2686file (i.e., /.journal) to an hidden inode if the filesystem has been
2687opened read/write. This allows the users to add a journal while the
2688filesystem is mounted, but the next time the system is rebooted, the
2689journal file will disappear. This avoids problems with backups,
2690stupid operators with superuser bits, etc.
2691
2692Fix a bug in fsck where it would not support a filesystem type of
2693"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
2694
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002695Fsck now supports fstab entries of the form "ext3,ext2". It will also
2696automatically identify reiserfs filesystems.
2697
2698The number of processes spawned by fsck can now be limited using the
2699FSCK_MAX_INST environment variable.
2700
Theodore Ts'o446314f2001-12-24 15:22:27 -05002701Fsck now searchs the LVM proc hierarchy to find logical volumes which
2702should be searched for UUID and label information.
2703
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002704Work around a bug in 2.4.10+ kernels by trying to unset the filesize
2705limit if at all possible, when opening a block device. (The filesize
2706limit shouldn't be applied against writes to a block device.)
2707
Theodore Ts'o446314f2001-12-24 15:22:27 -05002708In mke2fs and e2fsck, specifying the -c option twice will now do
2709a read/write test on the disk. Update the man pages to encourage
2710using the -c option, and to discouraging running badblocks separately,
2711since users tend to forget to set the blocksize when running
2712badblocks.
2713
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002714Mke2fs now automatically clears the immutable attribute on a
2715pre-existing .journal file left over from a previous failed attempt to
2716add a journal to an alreadyy-mounted filesystem.
2717
2718Fixed mke2fs's exit codes to consistently indicate when the mke2fs
2719operation failed.
2720
Theodore Ts'o446314f2001-12-24 15:22:27 -05002721Mke2fs now creates the lost+found directory with permissions of 0700,
2722so that files that had previously lived in protected directory are
2723safe if they get dropped in lost+found and the system administrator
2724doesn't deal with immediately. (Addresses Debian #bug 118443)
2725
2726Mke2fs and e2fsck (and all programs that use the
2727ext2fs_check_if_mounted function) will now properly identify that a
2728device is mounted, even in cases where devfs has confused things with
2729multiple devices names with the same identity, or if a dim-witted
2730system administrator has done something stupid like creating device
2731file aliases in their home directory. Also now checks for swap devices
2732by using /proc/swaps. (Addresses Debian bug #106622)
2733
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002734Added a new option (-T) to tune2fs which sets the time a filesystem
2735was last checked.
2736
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002737Speed up e2image when creating sparse raw image files by optimizing
2738away excess lseek() system calls.
2739
2740Fix support of large (> 2GB) files when used as a filesystem in
2741mke2fs, tune2fs, debugfs, and findsuper.
2742
2743Debugfs's stat and icheck commands now properly deals with large (>
27442GB) files.
2745
2746Debugfs's set_super_value command now prints out the list of valid
2747superblock fields which can be set using the command.
2748
Theodore Ts'o446314f2001-12-24 15:22:27 -05002749Debugfs's rm and kill_file command now updates the superblock free block
2750and inode counts, thus keeping the filesystem consistent.
2751
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002752Debugfs's lsdel command now takes an optional argument which allows
2753the user to only see the most recently deleted files.
2754
2755A new command (undel) was added to debugfs which automates
2756undeleting a deleted inode and linking it back to a directory.
2757
2758Debugfs's ls command now takes a new option, -d, which lists
2759deleted directory entries.
2760
2761Debugfs's testb, freeb, setb, and find_free_block commands now take an
2762optional count argument.
2763
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002764Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
2765be used to signal that a particular inode should not be eligible for
2766tail-merging --- this is needed for programs like LILO.
2767
2768The findsuper (an unreleased, uninstalled utility program) has been
2769improved to add extra validity checks and to add a progress meter.
2770(It is still an unsupported program; the officially supported way to
2771recover from a trashed partition table is to use gpart; findsuper is
2772for wizards only. :-)
2773
2774Debugfs was fixed to compile with "configure --disable-swapfs".
2775
Theodore Ts'o446314f2001-12-24 15:22:27 -05002776Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002777
2778Added new translation file for Turkish.
2779
Theodore Ts'o446314f2001-12-24 15:22:27 -05002780Programmer's notes:
2781-------------------
2782
2783Fix general gcc -Wall complaints.
2784
2785E2fsprogs (mostly) works with the dietlibc.
2786
2787The programming texinfo file has been expanded to include description
2788of additional libext2fs functions. (Still not compeltely done, but a
2789lot of the more important functions have been documented.)
2790
2791Added a umask structure to struct_ext2_filsys, which currently only
2792modifies the behaviour of ext2fs_mkdir(), but if we add any file
2793creation functions to libext2fs, we should also make sure they respect
2794the umask setting.
2795
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002796The build-rpm script was fixed to be a bit more safe.
2797
2798The tests' Makefile now has a way of automating test case creation
2799for e2fsck, using "make testnew".
2800
2801Created a new function, ext2fs_dir_iterate2 which passes more
2802information to the callback function (identical to the one used by
2803ext2fs_dblist_dir_iterate). The directory iterator functions take a
2804new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
2805directory entries. If the directory entry is deleted, the callback
2806function will be called with the entry paraemter set to
2807DIRENT_DELETED_FILE.
2808
2809Added new functions, ext2fs_inode_alloc_stats and
2810ext2fs_block_alloc_stats, which takes updates block/inode allocation
2811statistics in the bitmaps, block group descriptors, and superblock
2812when inodes or blocks are allocated or deallocated.
2813

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04002815E2fsprogs 1.25 (September 20, 2001)
2816===================================
2817
2818This is primarily a bug-fix release; no new features were added, but
2819there are a number of embarassing bug fixes and cleanups applied.
2820
2821Fix a bug mke2fs which causes stack garbage to be written to disk when
2822zapping disk sectors. (This bug could cause mke2fs to core dump for
2823some kernels, I suspect with security enhancement patches.)
2824
2825Remove unneeded #include of <linux/config.h> which was breaking
2826building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
2827
2828Updated tune2fs man page to reflect the fact that adding or removing a
2829journal doesn't require running e2fsck.
2830
2831Remove use of AC_REQUIRE from autoconf which had been used to prevent
2832AC_CANONICAL_HOST from being called twice; unfortunately this causes
2833recent autoconf to bomb out since they don't allow AC_REQUIRE to be
2834used outside of autoconf macros. Fortunately, it doesn't seem to be
2835necessary any more, anyway.
2836
2837E2fsck will now not fall back to an alternate superblock if the user
2838specifies the superblock location explicitly on the command-line.
2839This allows easier recovery from a situation where the primary
2840superblock and block groups are slightly corrupted, but the backup
2841superblocks are completely broken.
2842
2843Fix problem which caused compile_et and mk_cmds to blow up if
2844e2fsprogs was in a directory with a pathname that contained spaces.
2845
2846We are now more paranoid about checking the entry in /etc/mtab to make
2847sure the filesystem is really mounted, since some broken distributions
2848(read: Slackware) don't initialize /etc/mtab before checking non-root
2849filesystems. (Slackware also doesn't check the root filesystem
2850separately, and reboot if the root filesystem had changes applied to
2851it, which is dangerous and broken, but there's nothing I can do about
2852that.)
2853
2854Make UUID library C++ friendly by adding appropriate extern "C"
2855declarations and using const in the function declarations.
2856
2857Fix up the com_err texinfo file so that it can product a valid info
2858file (previously, it could only be used to generate paper
2859documentation using texinfo.tex).
2860
2861
Theodore Ts'ofb707752001-09-04 15:00:37 -04002862E2fsprogs 1.24a (September 2, 2001)
2863===================================
2864
2865Fix brown-paper bug in mke2fs which caused it to segfault when
2866printing the version string.
2867
2868
Theodore Ts'o109624a2001-08-31 00:59:55 -04002869E2fsprogs 1.24 (August 30, 2001)
2870================================
2871
2872Revert the BLKGETSIZE64 support, since for some distributions, this
2873ioctl has been used by an unofficial kernel patch to update the last
2874sector on the disk, and this was causing disk corruption problems as a
2875result.
2876
2877Mke2fs is now more careful about zapping swap space signatures and
2878other filesystem/raid superblock magic values so that programs like
2879mount who try to use hueristics to determine the filesystem type of a
2880partition are less likely to be confused.
2881
2882E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
2883regular file (since Andreas Dilger's on-line resizing tools will set
2884its mode bits).
2885
2886Fixed some minor texinfo, man pages nits for spelling errors,
2887texinfo warnings, etc. (Addresses Debian bug #110621.)
2888
2889E2fsprogs program no longer print the filesystem version number
2890(i.e. 0.5b), since it only confuses people and doesn't serve any real
2891purpose.
2892
2893E2fsck will once again compile under libc5, since it will supply its
2894own version of strnlen if necesssary.
2895
2896mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
2897when specifying the external journal device. tune2fs will also search
2898devices looking for the externla journal debice when removing.
2899
2900E2fsprogs 1.23 (August 15, 2001)
2901================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002902
2903Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04002904correctly handle a filesystem with EA's and check the EA blocks for
2905corruptions.
2906
Theodore Ts'od494bba2001-08-09 06:14:42 -04002907E2fsck's symlink sanity checking has been cleaned up. It now checks
2908the i_size value of fast symlinks, and checks for immutable flags
2909being set of symlinks, etc.
2910
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002911E2fsck now offers to clear inodes which are special files that have a
2912non-zero i_blocks or i_size field. (The i_size field check was in the
2913previous version of the code, but due to a bug it didn't offer to
2914clear the inode unless i_size and i_size_high were both non-zero.)
2915
Theodore Ts'od494bba2001-08-09 06:14:42 -04002916E2image can now create "raw" image files, which only contain the
2917filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
2918debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04002919
2920Add support for the 64-bit block device patches.
2921
2922Fixed bugs in creating external journals with a 1k blocksize.
2923
Theodore Ts'od494bba2001-08-09 06:14:42 -04002924Add initial support for external journals (so long as the external
2925journal only supports a single filesystem) in e2fsck.
2926
2927Remove requirement for needing to run fsck on a filesystem after
2928removing a journal (either internal or external).
2929
Theodore Ts'obf16d102001-07-27 22:20:06 -04002930The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002931
2932Speed up the check of an ext3 filesystems by avoiding a needless flush
2933of all of the superblock and block group descriptors.
2934
Theodore Ts'od494bba2001-08-09 06:14:42 -04002935Speed up creating an internal journal using tune2fs in the case where
2936the filesystem has a lot blocks already allocated.
2937
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002938Tune2fs has been fixed to make sure that only error messages go to
2939stderr, and normal message go to stdout. (Addresses Debian bug #108555)
2940
Theodore Ts'od494bba2001-08-09 06:14:42 -04002941Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002942now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04002943
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002944Add support in fsck for the filesystem type "auto".
2945
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002946Fsck -A will not try to interpret device names for filesystems which
2947have a pass number is 0. (Addresses Debian bug #106696).
2948
2949Fsck prints a warning message if now valid filesystems are passed to
2950it. (Addresses Debian Bug #107458.)
2951
Theodore Ts'o9249d982001-07-20 18:14:10 -04002952E2fsck now gives an explicit warning if there filesystem still has
2953errors at the end of the run. (Addresses Debian bug #104502)
2954
Theodore Ts'od494bba2001-08-09 06:14:42 -04002955E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002956reflects an error. E2fsck will also not run the orphan list if the
2957filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04002958
2959E2fsck now prints the number of large files when given the -v option.
2960
2961Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04002962
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002963Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04002964
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002965
Theodore Ts'o19d6b542001-06-23 00:13:09 -04002966E2fsprogs 1.22 (June 22, 2001)
2967==============================
2968
2969Fixed a bug in e2fsck's handling of orphan inodes which are special
2970files (i.e., block/character device files, named FIFO's, etc.).
2971
2972Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
2973tune2fs to fail at adding a journal to a mounted filesystem.
2974
2975Fixed a few big-endian bugs in e2fsprogs
2976 * The directory block functions were accidentally reporting
2977 some directories as corrupted when they weren't.
2978 * If e2fsprogs is compiled --disable-swapfs, the C language
2979 equivalents weren't being included for big-endian platforms.
2980 (Fixes Debian bug #101686).
2981
2982Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
2983
2984Programmer's notes:
2985-------------------
2986
2987Use platform independent method of defining the BLKFLSBUF and FDFLUSH
2988ioctls, and allow them to be defined for non-i386 platforms.
2989
2990The uuid.h header file is now protected against multiple inclusions.
2991
2992E2fsprogs is now being developed using BitKeeper. Changed the test
2993scripts to deal with BK's stripping CR characgters from text files,
2994and changed the top-level Makefile.in to avoid including BitKeeper
2995files when generating the source tarball.
2996
2997
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002998E2fsprogs 1.21 (June 15, 2001)
2999==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00003000
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003001Added new configure flags which allow a subset e2fsprogs to be built;
3002this is most useful for boot floopies, since the resulting shared
3003libraries and programs are slimmed down by removing features that
3004aren't necessary for a boot floppy. The new flags that were added
3005are: --disable-swapfs, which removes support for byte swapping old
3006legacy PPC/68k filesystems, --disable-debugfs, which removes support
3007for debugfs from the libext2fs library, --disable-imager, which
3008removes support for the e2image program, and --disable-resizer, which
3009removes support for resize2fs.
3010
3011E2fsck now prints the number of mounts or days elapsed since the last
3012check when e2fsck is forced to check an otherwise clean filesystem.
3013
3014Tune2fs now prints an informative message about how often a filesystem
3015will be checked when adding a journal to the filesystem, to remind the
3016user that he/she may want to adjust those parameters using tune2fs
3017-c/-i.
3018
3019Worked around hurd brain-damage which causes e2fsck to sometimes
3020believe a filesystem is the root filesystem based on device numbers
3021(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
3022violation).
3023
3024Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
3025erroneous error with the -F option was specified.
3026
3027Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003028ext3 0.7a.
3029
Theodore Ts'o767de092001-06-02 01:20:18 +00003030Fixed two bugs in e2fsck's handling of dup block handling, dealing
3031with relatively uncommon edge cases: a directory with an indirect
3032block which is claimed by another file, and when the last inode in the
3033filesystem has blocks claimed by another file.
3034
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00003035E2fsck now checks to see if the i_size field of a fast symlink is too
3036big, and offers to clear the symlink if so.
3037
3038E2fsck now checks to see if i_size_high of special files is non-zero,
3039and offers to clear i_size_high.
3040
Theodore Ts'o767de092001-06-02 01:20:18 +00003041Fix e2fsck's handling of incompatible journal flags so that the user
3042has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00003043entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00003044
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003045Fixed a bug in fsck which could cause it to core dump if a mix of
3046standard and non-standard device names are used in /etc/fstab.
3047(Debian bug #100559)
3048
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003049Fixed a bug in debugfs which caused read errors when copying a file to
3050not be noticed.
3051
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003052The debugfs set_super_value command can now modify the s_lastcheck field.
3053
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003054Fixed a bug in lsattr and chattr which was accidentally introduced in
30551.20 to support > 2GB files; both lsattr and chattr wasn't reading
3056directories correctly because the change modified the layout of struct
3057dirent to be incompatible with the libe2p shared library.
3058
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003059Cleaned up the mke2fs manual page and included a discussion about why
3060it's good to periodically check the filesystem even when journaling is
3061enabled.
3062
Theodore Ts'o767de092001-06-02 01:20:18 +00003063Programmer's notes:
3064-------------------
3065
3066Fix general gcc -Wall complaints.
3067
3068The types needed by the ext2 header files are now provided by
3069lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
3070
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003071Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003072in ext2_types.h. Also, if linux/types.h has already been defined,
3073don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003074
Theodore Ts'o767de092001-06-02 01:20:18 +00003075Fixed make depend script so that it automatically corrects the
3076pathname cleanups performed by make -M, so I don't have to fix them up
3077by hand.
3078
3079Fixed the d_loaddump test case to be more robust, and not depend on
3080bash'isms.
3081
3082Removed debugfs's dependence on pread(), which was accidentally
3083intrudced in e2fsprogs 1.20
3084
Theodore Ts'oc05b5522001-06-08 12:03:36 +00003085Fixed a performance bug in the libext2fs's icount routine; the size
3086estimate of the icount array was incorrectly being calculated.
3087
Theodore Ts'ob90b8262001-06-15 22:54:34 +00003088Removed use of the badblocks compatibility functions in the e2fsprogs
3089programs.
3090
3091Added paranoia code which protects against strange cases where /etc
3092isn't on the root filesystem, or if /etc/mtab doesn't exist.
3093
3094The header file ext2_types.h is now installed.
3095
3096Autoconf is used to determine when we are on big-endian machines,
3097instead of doing run-time tests, to save a few bytes of code.
3098
3099The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
3100functions are no longer inline functions, which saves space and
3101doesn't really cost any real performance.
3102
3103The ext2fs library no longer depends on the e2p library. (What need
3104there was of it --- namely, fsetflags, was coded in-line).
3105
3106Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
3107when the user is stupid and tries compiling the package using "make
3108install" as root.
3109
3110Miscellaneous code cleanups:
3111 * Added missing files from Makefile.in's SRCS file, so that
3112 their dependencies would be properly calculated.
3113 * Removed redundant code
3114 * Fixed comments in code
3115 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00003118E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003119=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00003120
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003121Add support for replaying the ext3 journal purely in user mode,
3122including handling the orphaned inode list. Used code contributed by
3123Andreas Dilger, with bug fixes and the orphaned inode handling done
3124by Theodore Ts'o.
3125
3126The mke2fs and tune2fs programs can create or modify a filesystem to
3127include an ext3 journal. Tune2fs also can be used to remove an ext3
3128journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00003129
3130E2fsck will now check for the existence of a linked list of orphan
3131inodes in the superblock, and clear those inodes before starting the
3132rest of the filesystem check (but after the journal playback).
3133
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003134E2fsck now validates the file descriptor passed to the -C option,
3135which saves against the completion bar getting written to an
3136unexpected location, such as the disk being checked. (Debian
3137bug/wishlist #55220)
3138
3139E2fsck will now bump the filesystem revision number from zero to one
3140if any of the compatibility bits are set.
3141
3142Fixed a bug where a badly corrupted directory on a big endian system
3143could cause e2fsck to die with a bus error. The
3144ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
3145the ext2 library now does alignment sanity checks on the rec_len field
3146of the directory entry before using it.
3147
3148The ext2 library has been enhanced to make tune2fs safe to run on
3149mounted filesystems. (Users could usually get away with using tune2fs
3150on mounted filesystems before, but with the advent of ext3 and
3151journaling, it became important to make tune2fs was *really* safe for
3152use even when the filesystem being modified is mounted.) E2label is
3153now implemented by tune2fs using an argv[0] dispatch, so that e2label
3154is also now safe for use on mounted filesystems.
3155
3156Added a new program, e2image, which creates a backup of critical ext2
3157filesystem data structures. The generated image file can be examined
3158using dumpe2fs and debugfs. In the future, e2fsck will be able to use
3159the image file to help recover very badly damaged filesystems.
3160
3161Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
3162no longer cause e2fsck to bomb out. Also treat files > 2GB as being
3163large file when deciding whether or not the filesystem has large files.
3164
3165Fixed lsattr and chattr so that they work correctly on large files.
3166(Fixes Debian bug #72690.)
3167
3168Removed limitation in get_device_size() which imposed a one terrabyte
3169filesystem limitation. (Most 2.2 kernels still have a signed int
3170problem which cause 1 TB block device limitation. Fortunately, the
3171kernel patches to fix this are much easier than fixing the 2TB
3172limitation in the kernel. :-)
3173
3174A max_mount_count of zero is now treated as if no mount count were
3175set. (Previously, no mount count was indicated by using -1, and a
3176mount count of zero caused e2fsck to always be run.)
3177
Theodore Ts'o77648562001-05-14 13:04:44 +00003178Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003179
3180Mke2fs now adds some randomness in s_max_mount_count so that multiple
3181filesystems won't be all checked at the same time under normal
3182operations.
3183
Theodore Ts'o5570a652000-08-21 01:23:39 +00003184Fixed bug in the progress bar printing code which could cause e2fsck
3185to core dump on an illegal filesystem.
3186
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003187Fixed bug in fsck which could allow more than one instance of e2fsck
3188to be printing a progress bar. (Debian bug #65267)
3189
Theodore Ts'o5570a652000-08-21 01:23:39 +00003190Fsck using a UUID or a LABEL specifier will work even if devfs is
3191compiled into the kernel and not mounted. If the pathnames in
3192/proc/partitions are incorrect, fsck will search /dev for the correct
3193device (using the new ext2fs_find_block_device library function).
3194Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003195found when they are in use. Support has also been added to support
3196additional IDE disks and the DAC 960 device names. (Debian bug #94159)
3197
3198Fixed a bug in fsck which caused it not deal properly with 16
3199byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00003200
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00003201Fsck's -t option has been made a lot more flexible. The semantics for
3202what happens if a comma-separated list to fsck has been regularized,
3203and it is now possible to filter what filesystems will get checked
3204based what is in the filesystem's fstab entry's option field. (Debian
3205bug #89483.)
3206
Theodore Ts'o5570a652000-08-21 01:23:39 +00003207The dumpe2fs program can now print out the group description
3208information in hex, and also prints the location of the superblock and
3209block group descriptor for those block groups that have them.
3210
3211Mke2fs now clears the ext2 superblock before it starts creating a
3212filesystem, so that the superblock magic number is only written if the
3213filesystem creation process successfully completes.
3214
3215The debugfs program's stat command now pretty-prints the blocks used
3216by an inode so that it's more compact and informative.
3217
3218The debugfs stats command now uses the same libe2p code (which is used
3219by dumpe2fs) to print the superblock header information. This is more
3220complete, and it avoids a bit of code duplication.
3221
3222Added a new debugfs command, set_super_value (ssv) which allows the
3223user to set arbitrary superblock fields.
3224
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003225Debugfs was extended to support inode numbers in hex (by prefixing
3226them with 0x), and so that modify_inode can set the inode generation
3227number. Also, there is now a new function command called logdump
3228which will dump an ext3 journal.
3229
3230Fixed a bug in debugfs so that quitting out of the pager doesn't kill
3231debugfs.
3232
3233Debugfs's dump command now stops immediately upon reporting a disk
3234read error. (Fixed a bug in ext2fs_file_read library routine which
3235caused debugfs not to stop.) (Debian bug #79163)
3236
3237On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
3238checked before /etc/mtab is used, since /proc/mounts is more likely to
3239be accurate.
3240
3241Added portability fixes for Solaris and Linux/ia64.
3242
3243Various manual pages were clarified and cleaned up. (Fixed debian
3244bugs #63442, #67446, and #87216)
3245
Theodore Ts'o5570a652000-08-21 01:23:39 +00003246
3247Programmer's notes:
3248-------------------
3249
3250The e2fsck message printer now supports %Iu and %Ig, which will print
3251out the inode's user and group owners, respectively.
3252
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003253E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
3254that no longer dependent on the system having the correct version of
3255the kernel header files.
3256
Theodore Ts'o5570a652000-08-21 01:23:39 +00003257Added a new function to libext2, ext2fs_find_block_device(), which
3258searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
3259device given its device number.
3260
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003261Added a new function to libext2, ext2fs_sync_device, which centralizes
3262all of the places which might try to use the BLKFLSBUF or FDFLUSH
3263ioctls (and usually failing to define them since the system header
3264files don't usually do this for us, and we're trying to avoid usage of
3265kernel include files now).
3266
Theodore Ts'o5570a652000-08-21 01:23:39 +00003267Added new utility programs in tests/progs: random_exercise and
3268hold_inode. They aren't built by default; they're useful for
3269exercising ext3 filesystem code.
3270
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003271Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
3272the filesystem close functions to only update the superblock, and to
3273not touch the block group descriptors. Needed by tune2fs when
3274modifying a mounted filesystem.
3275
3276Got rid of struct ext2fs_sb and replaced it with the standard struct
3277ext2_super_block from include/linux/ext2_fs.h. Note: this may break
3278source (but not binary) compatibility of some users of the ext2
3279library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00003280replace of struct ext2fs_sb with struct ext2_super_block, and include
3281the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003282
3283The ino_t type has been renamed ext2_ino_t to protect applications
3284that attempt to compile -D_FILE_OFFSET_BITS=64, since this
3285inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
3286unexpected ABI change.
3287
3288The Makefiles have been reworked so that "make check" can be run from
3289the top-level Makefile.
3290
3291Fix general gcc -Wall complaints and removed dead code.
3292
3293Remove use of NOARGS, because we assume everyone does ANSI C these
3294days.
3295
3296Added build-rpm script from sct.
3297
3298New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
3299to support e2image.
3300
3301New function ext2fs_flush_icache which must be called if the
3302application program modifies the inode table blocks without going
3303through ext2fs_write_inode() interface.
3304
3305New ext2fs_check_mount_point() function, which will return the mount
3306point of a device if mounted.
3307
3308The io_channel abstraction now has an optional interface,
3309io_channel_write_range, which allows specific byte ranges to be
3310written.
3311
3312The unix_io IO channel now supports write-through caching, so that
3313journal creation is more efficient.
3314
3315Added x86 assembly language routines to support byte swapping, to
3316reduce executable size.
3317
3318Fixed bug in the utility program subst so that it's possible to
3319replace a substitution variable with a zero-length string.
3320
3321Fixed numbering e2fsck pass1 problem numbers; an extra zero had
3322slipped into some of the problem number.

Theodore Ts'ob777e262000-07-27 01:39:23 +00003324E2fsprogs 1.19 (July 13, 2000)
3325==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00003326
3327Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00003328be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00003329
3330Add experimental support needed for the ext2 compression patches.
3331This requires compiling e2fsprogs with the --enable-compression flag
3332to the configure script.
3333
3334Added ext3 journalling support. E2fsck will run the journal (if
3335necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
3336installed as a symlink to e2fsck. Fsck has been taught about ext3,
3337and treats it the same as ext2 in terms of the progress bar logic.
3338Dumpe2fs will display the superblock journaling information if the
3339filesystem has a journal. The ext2 library will now permit opening an
3340ext3 filesystem with the recovery flag set. This is necessary for
3341on-line dump's to work correctly, but there may be issues with this
3342working well since ext3 is much less agressive about syncing blocks to
3343the filesystem, since they're safe on the journal.
3344
3345Tune2fs and e2fsck have been changed to allow the mount_count check to
3346be disabled by setting max_mount_count to -1. (This was already
3347supported by the kernel.)
3348
3349Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
3350are used for ext3 as well.
3351
3352Added internationalization support for e2fsprogs; must be enabled
3353by passing --enable-nls to configure.
3354
3355Always use the provided ext2fs header files to insulate ourselves from
3356kernel version changes. Which include files are used by e2fsprogs
3357have also been cleaned up to improve portability.
3358
3359Limit the number of times that e2fsck updates the progress bar so that
3360people who are booting using a 9600 baud console don't get swampped by
3361too many updates.
3362
3363Improved the loop detection algorithm in e2sck's pass #3 so that it is
3364much, much faster for large filesystems with a large number of
3365directories.
3366
3367The memory footprint for e2fsck is now slightly smaller than before.
3368
3369E2fsck now checks if special devices have a non-zero size, and offers
3370to clear the size field if it finds such an inode.
3371
3372E2fsck now checks if special devices have the append-only flag set,
3373and offers to clear the inode.
3374
3375E2fsck now properly handles some "should never fail" cases during a
3376bitmap copy in pass5.
3377
3378E2fsck now properly prints control characters in filenames as ^A .. ^Z.
3379
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003380E2fsck now calculates the correct location of the backup superblock in
3381the case of filesystem blocksizes > 1k.
3382
3383Fixed a bug in e2fsck's calculation of the number of inodes_per_block
3384which normally didn't cause problems under most filesystem parameters,
3385but could cause a valid superblock to be rejected in extreme cases.
3386Other checks for validating superblock values were made more
3387stringent.
3388
Theodore Ts'oab146762000-07-07 04:37:35 +00003389Added non-destructive write testing to the badblocks program, courtesy
3390of David Beattie. The badblocks also now has an option to input the
3391current set of bad blocks, so that known bad blocks are skipped to
3392speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00003393feature which causes badblocks to run until it has completed some
3394number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00003395
3396Badblocks now checks to see if the device is mounted and refuses to do
3397the tests involving writing to the device if it is mounted. Also,
3398badblocks now allows the number of blocks to be checked to be
3399defaulted to the size of the partition.
3400
3401Fixed a bug in fsck which didn't allow non-root users to be able to
3402check filesystems if there were any LABEL= or UUID= entries in
3403/etc/fstab.
3404
3405The Hurd doesn't support the filetype filesystem feature. The mke2fs
3406program now makes sure that for the Hurd, the filestype feature is
3407turned off. E2fsck will check to see if the filetype feature is
3408turned on for Hurd filesystems, and offer to turn off the feature.
3409
3410Mke2fs now has a safety check to make sure the number of blocks do not
3411exceed 32 bits even on a 64 bit platform.
3412
3413Really fixed a bug in fsck to allow "fsck -As" to run interactive
3414fsck's. (For those people who like to do interactive fsck's in the
3415/etc/rc scripts!?!)
3416
3417Debugfs has a few new features: the rdump command, which will do a
3418recursive dump of a directory and all of its contents, and the lcd
3419command which does a local chdir (much like the ftp command of the
3420same name). In addition, the debugfs program and the open_filesystem
3421command now takes three new options: -b and -s, which allows the
3422blocksize and superblock location to be specified, and the -c option
3423which is used in catastrophic situations where the block group
3424descriptors are corrupt. If the -c option is specified, debugfs will
3425skip trying to read in the block and inode bitmaps.
3426
3427Debufs's lsdel command was fixed to handle bad blocks in the inode
3428table.
3429
3430A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
34314 digit years.
3432
3433General improvements in error messages
3434
3435 - Mke2fs prints a sane error message if the partition size is zero
3436 (usually because the partition table wasn't reread by the
3437 kernel due to the partition being busy), instead of "invalid
3438 argument passed to ext2 library while initializing superblock".
3439
3440 - Fsck now prints more self-explanatory message if an invalid UUID=
3441 or LABEL= specification is passed to it.
3442
3443UUID library changed to use the LGPL.
3444
3445Fixed a bug in the UUID library where very rapid calls to the
3446time-based UUID generator could cause duplicate UUID's to be returned.
3447This was not a problem for e2fsprogs, but it could be a problem for
3448other users of the library.
3449
3450Make the UUID library more robust in the face of missing or an
3451improper /dev/urandom or /dev/random files.
3452
3453Added some random portability fixes for Solaris.
3454
3455Some minor man page updates.
3456
3457Fixed a memory leak in the ss library.
3458
3459
3460Programmer's notes:
3461-------------------
3462
3463We now try to use lseek64 and open64 from the LFS if possible.
3464
3465The 3rd parameter in e2p's print_flags is now a flags word, instead of
3466a boolean option.
3467
3468The mark and unmark bitmap functions now return the previous state of
3469the bit that was being changed, which is useful for some speed
3470optimizations.
3471
3472The following functions have been added to enhance the badblocks list
3473handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3474ext2fs_badblocks_equal.
3475
3476The ext2 header files now have the latest journalling fields to the
3477superblock.
3478
3479The ext2fs_mkdir function in libext2fs now properly backs out of error
3480conditions robustly.
3481
3482Cleaned up makefiles:
3483 - to cleanly compile with the -j flag.
3484 - so distclean removes all generated files.
3485 - so in case of an error while installing header files, the make aborts.
3486
3487Fix test_script so that it works correctly when compiling in the
3488source directory.
3489
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003490The random UUID generation routine has been made slightly better in
3491the case where /dev/random doesn't exist. (Use of randomly-based UUID
3492is still not recommended if /dev/random doesn't exist, however; it's
3493better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00003494
3495Clean up the build process so it's more friendly in case of missing
3496directories.
3497
3498The ext2fs header file can now be #include'd into C++ programs.
3499
3500The e2p.h header file is now installed.
3501
3502Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3503
3504
3505
Theodore Ts'o24ded091999-11-10 15:56:16 +00003506E2fsprogs 1.18 (November 10, 1999)
3507==================================
3508
3509Fix a core dumping bug in e2fsck if an imagic inode is present or
3510(more rarely) if the filesystem is badly corrupted enough that e2fsck
3511has to restart pass 1 processing. E2fsck now closes the filesystem
3512before freeing a large number of its data structures, so in the case
3513of future memory faults, at least the fixed filesystem will be fully
3514written out.
3515
3516If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3517imagic inode, it will offer to clear the imagic flag.
3518
3519E2fsck will now offer to clear the immutable flag on special files
3520(device/socket/fifos) when running it in non-preen mode.
3521
3522E2fsck will now set the filetype when creating /lost+found, and when
3523connected orphaned inodes to /lost+found.
3524
3525Debugfs's ncheck and icheck commands now handles the case where there
3526are bad blocks in the inode table without bombing out.
3527
3528The badblocks list processing code has been made more efficiently for
3529appending a large number of (ordered) badblocks to the badblocks list.
3530
3531Some minor man page updates.
3532
3533Fsck now allows interactive e2fsck's when using fsck -As (not a common
3534mode, but some people like to do this in boot scripts for silly reasons).
3535
3536Programmer's notes:
3537-------------------
3538
3539The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3540with the problem code convention.
3541
3542The badblocks list regression test program has been updated to work
3543with previously made API name changes.
3544
3545The ext2fs_free() command now uses the new badblocks API to avoid
3546using the compatibility layer.
3547
3548Added new regression test cases; the run_e2fsck test script now
3549supports the ability for a test case to run a prepratory command
3550before running e2fsck.
3551
Theodore Ts'o28e11941999-10-26 18:17:20 +00003552E2fsprogs 1.17 (October 26, 1999)
3553=================================
3554
3555Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3556infinite loop.
3557
3558Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3559thus potentially causing problems if a binary UUID contained a NULL
3560character.
3561
3562E2fsck now uses stricter checks for directory entries in pass 2:
3563zero-length filenames are not allowed; neither are 8 byte long
3564directory entries.
3565
3566The debugfs "dirty" command now clears the filesystem valid bit.
3567(Previously this just set the dirty-as-in-needs-writing-out-to-disk
3568bit in the in-core superblock image. The new functionality is more
3569what the user expects, and is more useful.)
3570
3571Added a debugging hook to test parallel fsck; if the environment
3572variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3573will be checked in parallel when they normally would not be.
3574
3575Programmer's notes:
3576-------------------
3577
3578Fixed some #ifdef's for compilation under the Hurd OS.
3579
3580Fixed minor W2K compatibility problems.
3581
3582Fixed some miscellaneous GCC warnings.
3583
3584
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00003585E2fsprogs 1.16 (October 22, 1999)
3586=================================
3587
3588Fixed a race condition bug in fsck; when printing a progress bar, if
3589checking multiple filesystems in parallel, it was possible for fsck to
3590send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3591handler, which would cause it to terminate with a signal 10.
3592
3593E2fsck now properly handles filesystems that have the
3594INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3595filesystem into using or not using FILETYPE feature.
3596
3597E2fsck now properly handles filesystems that have the IMAGIC feature
3598turned on (this is used on Linux AFS servers).
3599
3600The mke2fs program now creates filesystems that have the filetype and
3601sparse_superblock features enabled by default, unless it is run on a
3602pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3603so there is now a new flag -O which allows the user to specify with
3604which features she would like to create the filesystem; "mke2fs -O
3605none" will create a filesystsem compatible with 2.0 kernels.
3606
3607The tune2fs program now has a -O option which allows the user to set
3608and reset "safe" filesystem features. Currently, the only ones which
3609allows to be modified are the filetype and sparse_superblock features.
3610Note setting or clearing either feature will require running e2fsck on
3611the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3612requires that there is enough free space on the filesystem for the
3613extra superblocks which will be created by e2fsck.)
3614
3615Debugfs can now set and print filesystem features in the superblock
3616using the "features" command. Dumpe2fs will print out the complete
3617set of features when listing the superblock.
3618
3619Dumpe2fs has new options -f (force) and -h (header-only).
3620
3621Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3622message to come up. This could happen when decrementing or
3623incrementing a link count could result in an overflow.
3624
3625Fixed a bug in e2fsck where the block count on the lost+found
3626directory would not be properly incremented when the directory was
3627expanded to the point where an indirect block needed to be allocated.
3628
3629E2fsck now makes some additional sanity checks on the superblock to
3630avoid crashing or giving a memory allocation error if some of the
3631values in the superblock are unresonable (but the superblock otherwise
3632looks valid).
3633
3634Fixed a bug in e2fsck where a very badly corrupted filesystem might
3635require two passes to completely fix the filesystem. This happened if
3636an inode claimed blocks that was part of the filesystem metadata
3637(typically, when garbage was written into an inode table or indirect
3638block, since this kind of filesystem corruption normally doesn't
3639happen otherwise).
3640
3641On the Alpha, glibc declares st_flags although it isn't actually used;
3642the configure script was improved to detect this case so that
3643e2fsprogs can avoid using the non-functional stat field.
3644
3645The manual pages were updated to use a more consistent formatting
3646style consistent with standard Unix man pages. Mke2fs's man page
3647added documentation for a few previously undocumented options.
3648
3649Fixed minor display bugs in tune2fs and mke2fs.
3650
3651Programmer's notes:
3652-------------------
3653
3654Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
3655
3656Added features to parse and print feature strings into the e2p library.
3657(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
3658
3659ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
3660whose directory entries contain proper filetype information if the
3661filesystem supports it.
3662
3663ext2fs_link() now uses the low 3 bits of its flags parameter to pass
3664the directory entry filetype information. This is used to set the
3665directory entry filetype information if the filesystem supports it.
3666
3667Fixed a bug in ext2fs_expand_dir() where the block count in a
3668directory's inode would not be properly incremented when the directory
3669was expanded to the point where an indirect block needed to be
3670allocated.
3671
3672
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003673E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003674==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003675
3676Add configuration checks so that e2fsprogs will compile cleanly on
3677Linux 2.3 kernels that have renamed i_version to i_generation.
3678
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003679E2fsck now prints a progress/completion bar (and not just a simple
3680spinner) if the -C0 option is requested or if it receives a SIGUSR1
3681signal. Fsck will automatically manage the (potentially muliple)
3682e2fsck processes to print completion bars if it is given a -C option,
3683with the right thing happening if multiple filesystems are being
3684checked in parallel.
3685
3686Mke2fs now has better automatic hueristics to determine the filesystem
3687parameters to be used for a particular filesystem. Added a new option
3688-T which allows the user to specify how the filesystem is to be used,
3689which helps mke2fs do a better job selecting the filesystem parameters.
3690
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003691Mke2fs now creates revision 1 filesystems by default, and with the
3692sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00003693not understood by Linux 2.0 kernels, so they will only allow read-only
3694mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003695
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003696Fix bug where if /dev/null couldn't be opened (should never happen),
3697e2fsck would hang in a tight loop.
3698
3699Make e2fsck handle the case where /lost+found isn't a directory.
3700
3701E2fsck now uses mallinfo if it exists to get accurate statistics about
3702its memory usage.
3703
3704Fix bug in e2fsck where it wouldn't check to see if a disconnected
3705inode had any problems before connecting it to /lost+found.
3706
3707Add check to e2fsck so it makes sure that total number of inodes in
3708the filesystem is a sane number.
3709
3710Fix fencepost error when clearing an the end of the block bitmap which
3711caused the last block in the bitmap not to get cleared.
3712
3713Cleaned up a number of messages in e2fsck:
3714 * The message "Group's #'s copy of the group descriptor..."
3715 was fixed so that the correct number would be displayed.
3716 * Added missing space in the "disk write-protected" error messsage
3717 * Cleaned up the error message printed when a non-interactive
3718 e2fsck needs to abort a check because the filesystem
3719 appears to be mounted.
3720
3721Added a new command-line utility, uuidgen, which will create and print
3722a UUID.
3723
3724Make debugfs's icheck command more robust by checking to make sure an
3725inode has valid blocks before interarting over the inode's blocks.
3726
3727UUID generation now uses a random-based scheme whenever possible to
3728prevent potential privacy problems.
3729
3730Man pages for all of the UUID functions in the lirbary were added.
3731
3732Fixed bug in fsck so it won't coredump if a filesystem not in
3733/etc/fstab is given to it.
3734
3735Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
3736that most of the other mount utilities understands.
3737
3738Mke2fs will make a filesystem even if it appears mounted if the force
3739option is given.
3740
3741Dumpe2fs has new command-line options which allow a filesystem expert
3742to specify the superblock and blocksize when opening a filesystem.
3743This is mainly useful when examining the remains of a toasted
3744filesystem.
3745
3746The badblocks program has been updated to display correctly on disks
3747with large block numbers.
3748
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003749The badblocks program no longer gives spurious errors when errors
3750occur on non-block boundaries, which is common if the blocksize is
3751larger than 1k.
3752
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003753Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
3754MKE2FS_SYNC environment variable is set. This is to work around a VM
3755bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003756to trigger it even using a 2.2 kernel, but hopefully it will not be
3757needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003758
3759Fixed miscellaneous documentation and man pages.
3760
3761Programmer's notes:
3762-------------------
3763
3764Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
3765in e2fsck's pass1.c really should have been static.
3766
3767The return value of the uuid_compare() function was changed to make it
3768match with the convetions used by strcmp, memcmp, and Paul Leach's
3769UUID sample document.
3770
3771The "make depend" process has now been made more automated; it now
3772automatically word-wraps the dependencies, and only replaces source
3773Makefile.in if there has been a change in the dependencies. Also, a
3774top-level "make depend" now recurses through all the subdirectories
3775automatically.
3776
3777The Makefile in .../util has been changed so that subst is built using
3778the native C compiler during a cross-compilation, since the subst
3779program is only used during the build process. Also add an explicit
3780rule to build util/subst by cd'ing to the correct directory and
3781running Makefile.
3782
3783The man directories are defined in terms mandir, so that the configure
3784script can override the location of the manual pages.
3785
3786The config files have been updated to recognize new machine types for
3787both the i386 and alpha families.
3788
3789Fsck has been modified so that it will accurately create an
3790fsck_instance even when the noexecute flag is set. This allows for
3791accurate debugging of the fsck pass structure. Also, when the verbose
3792flag is given twice, fsck will print debugging information about when
3793fsck is waiting for jobs to finish.
3794
3795
Theodore Ts'o14790ed1999-01-12 23:32:52 +00003796E2fsprogs 1.14 (January 9, 1999)
3797================================
3798
3799Fix the fstab parsing code so that it can handle blank lines and
3800comment characters. Also, missing pass numbers need to be treated as
3801zero.
3802
3803Fixed a bug in e2fsck where under some circumstances (when e2fsck
3804needs to restart processing after fixing an egregious inconsistency)
3805it would try to access already freed memory.
3806
3807E2fsck now prints non-printable characters in directory entries and
3808pathnames using '^' and 'M-' notation.
3809
3810Fixed chattr so that it will ignore symbolic links when doing
3811recursive descent traversals. For both chattr and lsattr, no longer
3812print the version string unless the -V option is given.
3813
3814Allow the system administrator to directly specify the number of
3815inodes desired in the filesystem, for some special cases where this is
3816necessary.
3817
3818Fix portability problems so that e2fsprogs can be compiled under Linux
38191.2 systems and Solaris systems.
3820
3821Update the config.guess file with a more recent version that will
3822identify newer Linux platforms.
3823
3824Programmer's notes
3825------------------
3826
3827Ext2fs_read_inode and ext2fs_write_inode will now return an error if
3828an inode number of zero is passed to them.
3829
Theodore Ts'o556ad131998-12-19 08:10:58 +00003830E2fsprogs 1.13 (December 15, 1998)
3831==================================
3832
3833Fixed a bug in debugfs where an error messages weren't getting printed
3834when the ext2 library routines to read inodes returned errors in the
3835stat, cmri and rm commands.
3836
3837Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
3838provided, it won't create an inode table smaller than the minimum
3839number of inodes required for a proper ext2 filesystem.
3840
3841Fsck now parses the /etc/fstab file directly (instead of using
3842getmntent()), so that it can distinguish between a missing pass number
3843field and pass number field of zero. This caused problems for
3844diskless workstations where all of the filesystems in /etc/fstab have
3845an explicit pass number of zero, and fsck could not distinguish this
3846from a /etc/fstab file with missing pass numbers.
3847
3848E2fsck will create a /lost+found directory if there isn't one in the
3849filesystem, since it's safer to create the lost+found directory before
3850it's needed.
3851
3852Fixed e2fsck so that it would detect bogus immutable inodes which
3853happen to be sockets and FIFO files, and offer to clear them.
3854
3855If a filesystem has multiple reasons why it needs to be checked, and
3856one of the reasons is that it is uncleanly mounted, e2fsck will print
3857that as the reason why the filesystem is being checked.
3858
3859Cleaned up the output routines of mke2fs so that it doesn't overflow
3860an 80 column display when formating really big filesystems.
3861
3862Added a sanity check to e2fsck to make sure that file descriptors 0,
38631, 2 are open before opening the hard disk. This avoids a problem
3864where a broken program might exec e2fsck with those file descriptors
3865closed, which would cause disastrous results if the kernel returns a
3866file descriptor for the block device which is also used by FILE *
3867stdout.
3868
3869Fixed up the e2fsck progress reporting functions so that the values
3870reliably reach 100% at the completion of all of the e2fsck passes.
3871
3872Fixed minor documentation bugs in man pages and usage messages.
3873
3874Programmer's notes:
3875-------------------
3876
3877Fixed a number of lint warnings in the ext2fs library and potential
3878portability problems from other OS's header files that might define
3879CPP macros for names like "max" and "min".
3880
3881ext2fs_badblocks_list_add() has been made more efficient when it needs
3882to grow the bad blocks list.
3883
3884Fixed a bug in e2fsck which caused it to dereference a freed pointer
3885just before exiting.
3886
3887Fixed the substition process for generating the mk_cmds and compile_et
3888scripts so that they will work outside of the build tree.
3889
3890Add sanity check to e2fsck so that if an internal routine
3891(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
3892and causing a core dump. This should never happen, but...
3893
Theodore Ts'oa5696711998-07-09 05:38:07 +00003894E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00003895==================================
3896
3897E2fsprogs now works with glibc (at least with the version shipped wtih
3898RedHat 5.0). The ext2fs_llseek() function should now work even with
3899i386 ELF shared libraries and if llseek() is not present. We also
3900explicitly do a configure test to see if (a) llseek is in libc, and
3901(b) if llseek is declared in the system header files. (See standard
3902complaints about libc developers don't understand the concept of
3903compatibility with previous versions of libc.)
3904
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003905The ext2fs library now writes out the block group number in each of
3906the superblock copies. This makes it easier to automatically
3907determine the starting block group of the filesystem when the block
3908group information is trashed.
3909
3910Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00003911which means that e2fsprogs will ignore the high 8 bits of the
3912directory entry's name_len field, so that it can be used for other
3913purposes.
3914
3915Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
3916E2fsprogs will now support filesystems with 64-bit sized files.
3917
3918Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
3919
Theodore Ts'o21d53851998-02-21 03:14:50 +00003920Added new program "e2label", contributed by Andries Brouwer. E2label
3921provides an easy-to-use interface to modify the filesystem label.
3922
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00003923Fixed bug so that lsattr -v works instead of producing a core dump.
3924
Theodore Ts'o21d53851998-02-21 03:14:50 +00003925Fixed a minor bug in mke2fs so that all groups with bad superblock
3926backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00003927
3928Mke2fs will check the size of the device, and if the user specifies a
3929filesystem size larger than the apparent size of the device it will
3930print a warning message and ask if the user wants to proceed.
3931
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003932E2fsck has a new option -C, which sends completion information to the
3933specified file descriptor. For the most part, this is intended for
3934programs to use, although -C 0 will print a spinning character to the
3935stdout device, which may be useful for users who want to see something
3936happening while e2fsck goes about its business.
3937
Theodore Ts'o21d53851998-02-21 03:14:50 +00003938Fixed a bug in e2fsck which could cause a core dump when it needs to
3939expand the /lost+found directory, and sometimes the bitmaps haven't
3940been merged in. Also fixed a related bug where ext2fs_write_dir_block
3941was used to write out a non-directory block. (Which would be bad on a
3942non-Intel platform with byte swapping going on.)
3943
3944Fixed bug in e2fsck where it would print a "programming error" message
3945instead of correctly identifying where a bad block was in used when
3946the bad block was in a non-primary superblock or block group
3947descriptor. Also fixed a related bug when sparse superblocks are in
3948use and there is a bad block where a superblock or block group
3949descriptor would have been in a group that doesn't include a
3950superblock.
3951
3952Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
3953the block group descriptor table is corrupt, it was possible to try to
3954allocate a huge array, fail, and then abort e2fsck.
3955ext2fs_get_num_dirs() now sanity checks the block group descriptor,
3956and subsitutes reasonable values if the descriptors are obviously bogus.
3957
3958If e2fsck finds a device file which has the immutable flag set and the
3959i_blocks beyond the normal device number are non-zero, e2fsck will
3960offer to remove it, since it's probably caused by garbage in the inode
3961table.
3962
3963When opening a filesystem, e2fsck specially checks for the EROFS error
3964code, and prints a specific error message to the user which is more
3965user friendly.
3966
3967If the filesystem revision is too high, change the e2fsck to print
3968that this is either because e2fsck is out of date, or because the
3969superblock is corrupt.
3970
3971E2fsck now checks for directories that have duplicate '.' and '..'
3972entries, and fixes this corruption.
3973
3974E2fsck no longer forces a sync of the filesystem (with attendant sleep
3975calls) at all times. The ext2fs_flush() function now performs a sync
3976only if it needed to write data blocks to disk.
3977
3978Fixed a minor bug in e2fsck's pass1b's file cloning function, where
3979certain errors would not be properly reported.
3980
3981Updated and expanded a few points in the man pages which users
3982complained wheren't explicit enough.
3983
3984Added special case byte-swapping code if compiling on the PowerPC, to
3985accomodate the strange big-endian variant of the ext2 filesystem that
3986was previously used on the PowerPC port.
3987
3988
3989Programmer's notes:
3990-------------------
3991
3992Removed C++ keywords from the ext2fs libraries so that it could be
3993compiled with C++.
3994
3995E2fsck's internal organization has now been massively reorganized so
3996that pass*.c don't have any printf statements. Instead, all problems
3997are reported through the fix_problem() abstraction interface. E2fsck
3998has also been revamped so that it can be called as a library from a
3999application.
4000
4001Added new fileio primitives in libext2fs for reading and writing
4002files on an unmounted ext2 filesystem. This interface is now used by
4003debugfs.
4004
4005Added a new libext2fs function for mapping logical block numbers of
4006a file to a physical block number.
4007
4008Added a new libext2fs function, ext2fs_alloc_block(), which allocates
4009a block, zeros it, and updates the filesystem accounting records
4010appropriately.
4011
4012Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
4013sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
4014
4015The libext2fs functions now use a set of memory allocation wrapper
4016functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
4017instead of malloc, free, and resize. This makes it easier for us to
4018be ported to strange environments where malloc, et. al. aren't
4019necessarily available.
4020
4021Change the libext2fs fucntion to return ext2-specific error codes
4022(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
4023and depending on the existence of system error codes (such as EEXIST
4024and ENOENT).
4025
4026Renamed io.h to ext2_io.h to avoid collision with other OS's header
4027files.
4028
4029Add protection against ext2_io.h and ext2fs.h being included multiple
4030times.
4031
4032The types used for memory lengths, etc. have been made more portable.
4033In generla, the code has been made 16-bit safe. Added Mark
4034Habersack's contributed DOS disk i/o routines.
4035
4036Miscellaneous portability fixes, including not depending on char's
4037being signed.
4038
4039The io_channel structure has a new element, app_data, which is
4040initialized by the ext2fs routines to contain a copy of the filesystem
4041handle.
4042
4043ext2fs_check_directory()'s callback function may now return the error
4044EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
4045really do the checking, despite the presence of the callback function.
4046
4047
Theodore Ts'obc210071997-06-17 05:41:36 +00004048E2fsprosg 1.11 (June 17, 1997)
4049==============================
4050
4051Fixed e2fsck to detect (previously ignored) conflicts between the
4052superblock or block group descriptors and block bitmaps, inode
4053bitmaps, and inode tables.
4054
4055Fixed bug in e2fsck so that when the message printed out when a block
4056or inode bitmap conflicts with other data, it has the correct group
4057number.
4058
4059Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
4060to badblocks. This meant that not all of the filesystem was being
4061tested for bad blocks!
4062
4063Fixed an array boundary overrun case which cropped up in
4064ext2fs_badblocks_list_test when a user tried running "mke2fs -c
4065-b 4096".
4066
4067Adjusted the number of columns printed by mke2fs when displaying the
4068superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00004069really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00004070
4071Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
4072dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
4073fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
4074
4075Programmer's notes:
4076-------------------
4077
4078Fixed install rule in lib/ss so that ss_err.h is actually getting
4079installed.
4080
4081Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
4082bassed back to the caller.
4083
4084Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
4085setting the current inode number (which meant this function wasn't
4086working at all).
4087
4088Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
4089blocks in the bitmap when increasing the size of the bitmap.
4090
4091Changed the initial number of blocks allocated by ext2fs_init_dblist()
4092to be more realistic.
4093
4094Added a new function ext2fs_allocate_group_table, which sets up the
4095group descriptor information (and allocates inode and block bitmaps,
4096and inode tables for a particular group). The function was created by
4097factoring out code form ext2fs_allocate_tables().
4098
4099Added a new function ext2fs_move_blocks which takes a bitmap of the
4100blocks to be moved, and moves them to another location on the
4101boardboard.
4102
4103Make the unix_io channel's io_channel_flush implementation calls sync()
4104to to flush the kernel buffers to disk.
4105
4106Added a new function ext2fs_dblist_count returns the number of
4107directory blocks in dblist.
4108
4109
Theodore Ts'oae851481997-04-29 18:13:24 +00004110E2fsprogs 1.10 (April 24, 1997)
4111===============================
4112
4113Mke2fs once again defaults to creating revision #0 filesystems, since
4114people were complaining about breaking compatibility with 1.2 kernels.
4115Warning messages were added to the mke2fs and tune2fs man pages that
4116the sparse superblock option isn't supported by most kernels yet (1.2
4117and 2.0 both don't support parse superblocks.)
4118
4119Added new flag to mke2fs, -R <raid options>, which allows the user to
4120tell mke2fs about the RAID configuration of the filesystem. Currently
4121the only supported raid option is "stride" which specifies the width
4122of the RAID stripe.
4123
4124Fixed bug in e2fsck where pass1b would bomb out if there were any
4125blocks marked bad in the inode table.
4126
4127Fixed rare bug in mke2fs where if the user had a very unlucky number
4128of blocks in a filesystem (probability less than .002) the resulting
4129filesystem would be corrupt in the last block group.
4130
4131Fixed bug where if e2fsck tried to allocate a block to fix a
4132filesystem corruption problem and the filesystem had no free blocks,
4133ext2fs_new_block() would loop forever.
4134
4135The configure script now checks explicitly to see if "-static" works,
4136since that can't be assumed to be true --- RedHat doesn't install
4137libc-static by default.
4138
4139Fixed bug in libext2's block iterator functions where under some
4140cirmcustances, file with holes would cause the bcount parameter to the
4141callback function to be incorrect. This bug didn't affect any of
4142e2fsprogs programs, but it was discovered by Paul Mackerras, the
4143author of the PPC boot loader.
4144
4145Removed use of static variables to store the inode cache in libext2fs.
4146This caused problems if more than one filesystem was accessed via
4147libext2fs (static variables in libraries are generally a bad idea).
4148Again, this didn't affect e2fsprogs programs, but it was discovered by
4149Paul Mackerras.
4150
4151Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
4152will compile cleanly with 1.2.13 kernels (even with a.out shared
4153libraries!)
4154
4155Programmer's notes:
4156-------------------
4157
4158Added new functions to duplicate an ext2 filesystem handle, and its
4159associated substructure. New functions: ext2fs_dup_handle(),
4160ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
4161Other structures, such as the io_channel and the inode_cache, now have
4162a ref count so that they only get freed when they are no longer used
4163by any filesystem handle. (These functions were added as part of the
4164development effort for an ext2 resizer).
4165
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00004166E2fsprogs 1.09 (April 14, 1997)
4167===============================
4168
4169Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
4170accidentally introduced in the 1.08 release. The overhead calculation
4171was accidentally removed, which caused ext2fs_initialize() to not
4172notice when the filesystem size needed to be adjusted down because
4173there wasn't enough space in the last block group.
4174
4175Fixed bug in version parsing library routine; it was always parsing
4176the library version string, instead of using the passed-in string.
4177
4178Clarified chattr man page.
4179
Theodore Ts'o24757fa1997-04-29 17:39:27 +00004180E2fsprogs 1.08 (April 10, 1997)
4181===============================
4182
4183E2fsck 1.07 was very slow when checking very large filesystems with a
4184lot of files that had hard links (i.e., news spools). This was fixed
4185by seriously revamping the icount abstraction. Added a formal test
4186suite for the icount abstraction.
4187
4188Debugfs now has a "-l" option to the "ls" command, which lists the
4189inode number, permissions, owner, group, size, and name of the files
4190in the directory.
4191
4192Fix a bug in e2fsck where when a directory had its blocks moved to
4193another location during the pass 1b processing, the directory block
4194list wasn't updated, so pass 2 wouldn't check (and correct) the
4195correct directory block.
4196
4197E2fsck will now treat inodes which contain blocks which are claimed by
4198the filesystem metadata by treating them as multiply claimed blocks.
4199This way, the data in those blocks can be copied to a new block during
4200the pass 1b--1d processing.
4201
4202E2fsck will attempt to determine the correct superblock number and
4203display it in the diagnostic and warning messages if possible.
4204
4205Add support for a new (incompatible) feature, "sparse_super". This
4206feature reduces the number of blocks which contain copies of backup
4207superblocks and block group descriptors. (It is only an incompatible
4208feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
4209support a new -s option; e2fsck will recognize filesystems built with
4210this feature turned on.
4211
4212E2fsck now checks the library to make sure is the correct version,
4213using new library functions. (This helps to diagnose incorrectly
4214installed e2fsprogs distributions.)
4215
4216Dumpe2fs now prints more information; its now prints the the
4217filesystem revision number, the filesystem sparse_super feature (if
4218present), the block ranges for each block group, and the offset from
4219the beginning of the block group.
4220
4221Mke2fs now distributes the inode and block bitmap blok so that the
4222won't be concentrated in one or two disks in RAID/striping setups.
4223Also, if the user chooses a 2k or 4k block group, mke2fs will try to
4224choose the largest blocks per group that be chosen. (For 2k blocks,
4225you can have up to 16384 blocks/group; for 4k blocks, you can have up
4226to 32768 blocks/group.) Previously mke2fs would not allow
4227specification of more than 8192 blocks per group, even if you were
4228using a 2k or 4k block group.
4229
4230Programmer's notes:
4231-------------------
4232
4233Added a new function ext2fs_create_icount2() which takes a "hint"
4234argument. This hint argument presets the icount array with the list
4235of inodes which actually need to be in the icount array. This really
4236helps to speed up e2fsck.
4237
4238Added a new function ext2fs_icount_validate() which checks the rep
4239invariant for the icount structure. This is used mostly for testing.
4240
4241The error mesasage given when a bad inode number is passed to
4242test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
4243EXT2FS_UNMARK_ERROR).
4244
4245Added a new function ext2fs_set_dir_block which sets the block of a
4246dblist entry, given the directory inode and blockcnt.
4247
4248Added a new function ext2fs_get_library_version() which returns the
4249current library version, and ext2fs_parse_version_string() which
4250returns a version number based on a e2fsprogs version string.
4251
4252The icount functions will return EINVAL if the passed in inode number
4253is out of bounds.

Theodore Ts'o21c84b71997-04-29 16:15:03 +00004255E2fsprogs 1.07 (March 9, 1997)
4256==============================
4257
4258E2fsck is now uses much less memory when checking really large
4259filesystems (or rather, filesystems with a large number of inodes).
4260Previously a filesystem with 1 million inodes required 4 megabytes of
4261memory to store inode count statistics; that storage requirement has
4262now been reduced to roughly half a megabyte.
4263
4264E2fsck can now properly deal with bad blocks appearing inside the
4265inode table. Instead of trying to relocate the inode table (which
4266often failed because there wasn't enough space), the inodes in the bad
4267block are marked as in use.
4268
4269E2fsck will automatically try to use the backup superblocks if the
4270primary superblocks have a bad magic number or have missing meta-data
4271blocks (or meta-data blocks which are out of range).
4272
4273E2fsck's pass 3 has been made more efficient; most noticeable on
4274filesystems with a very large number of directories.
4275
4276Completely revamped e2fsck's system of printing problem reports. It
4277is now table driven, to make them more easily customizeable and
4278extendable. Error messages which can be printed out during preen mode
4279are now one line long.
4280
4281Fixed e2fsck's filesystem swapping code so that it won't try to swap
4282fast symbolic links or deleted files.
4283
4284Fixed e2fsck core dumping when fixing a filesystem which has no
4285directories (not even a root directory).
4286
4287Added a check to e2fsck to make sure that the length of every
4288directory entry is a multiple of 4 (since the kernel complains if it
4289isn't).
4290
4291Added a check to e2fsck to make sure that a directory entry isn't a
4292link to the root directory, since that isn't allowed.
4293
4294Added a check to e2fsk to now make sure the '.' and '..' directory
4295entries are null terminated, since the 2.0 kernel requires it.
4296
4297Added check to write_bitmaps() to make sure the superblock doesn't get
4298trashed if the inode or block bitmap is marked as being block zero.
4299
4300Added checking of the new feature set fields in the superblock, to
4301avoid dealing with new filesystem features that this package wasn't
4302set up to handle.
4303
4304Fixed a fencepost error in ext2fs_new_block() which would occasionally
4305try to allocate a block beyond the end of a filesystem.
4306
4307When the UUID library picks a random IEEE 802 address (because it
4308can't find one from a network card), it sets the multicast bit, to
4309avoid conflicting with a legitimate IEEE 802 address.
4310
4311Mke2fs now sets the root directory's owner to be the real uid of the
4312user running mke2fs. If the real uid is non-zero, it also sets
4313the group ownership of the root directory to be the real group-id of
4314the user running mke2fs.
4315
4316Mke2fs now has more intelligent error checking when it is given a
4317non-existent device.
4318
4319When badblocks is given the -vv option, it now updates the block that
4320it is currently testing on every block.
4321
4322Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
4323currently correctly if PATH wasn't already set.
4324
4325Shared libraries now built with dependencies. This allows the shared
4326library files to be used with dlopen(); it also makes the transition
4327to libc 6 easier, since ld.so can tell which libc a particular shared
4328library expects to use.
4329
4330Programmer's notes:
4331-------------------
4332
4333Added new abstraction (defined in dblist.c) for maintaining a list of
4334blocks which belongs to directories. This is used in e2fsck and other
4335programs which need to iterate over all directories.
4336
4337Added new functions which test to see if a contiguous range of blocks
4338(or inodes) are available. (ext2fs_*_bitmap_range).
4339
4340Added new function (ext2_inode_has_valid_blocks) which returns true if
4341an inode has valid blocks. (moved from e2fsck code).
4342
4343Added new function (ext2fs_allocate_tables) which allocates the
4344meta-data blocks as part of initializing a filesystem. (moved from
4345mke2fs code).
4346
4347Added a new I/O manager for testing purposes. It will either allow a
4348program to intercept I/O requests, or print debugging messages to
4349trace the activity of a program using the I/O manager.
4350
4351The badblocks_list functions now store the bad blocks in a sorted
4352order, and use a binary search to speed up badblocks_list_test.
4353
4354The inode scan function ext2fs_get_next_inode() may now return a soft
4355error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
4356those cases where part of an inode table is missing or there is a bad
4357block in the inode table.
4358
4359Added a new function (ext2fs_block_iterate2) which adds new arguments to
4360the callback function to return a pointer (block and offset) to the
4361reference of the block.
4362
4363Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
4364application to jump to a particular block group while doing an inode
4365scan.
4366
4367The badblocks list functions were renamed from badblocks_* to
4368ext2fs_badblocks_*. Backwards compatibility functions are available
4369for now, but programs should be modified to use the new interface.
4370
4371Some of the library functions were reorganized into separate files to
4372reduce the size of some programs which statically link against the
4373ext2 library.
4374
4375Put in some miscellaneous fixes for the Alpha platform.
4376
Theodore Ts'o5c576471997-04-29 15:29:49 +00004377
4378E2fsprogs 1.06 (October 7, 1996)
4379================================
4380
4381Fixed serious bug in e2fsck: if the block descriptors are bad, don't
4382smash the backup copies in ext2fs_close(). (The problem was that when
4383e2fsck -p discovered the problem, while it was closing the filesystem
4384and exiting, it was also blowing away the backup superblocks on the
4385disk, which was less than friendly.) We now make it the case that we
4386only write out the backup superblock and the back block descriptors if
4387the filesystem is completely free from problems.
4388
4389Fixed a bug in block_interate in the lib/ext2fs library which caused
4390e2fsck to fail on GNU Hurd-created filesystems.
4391
4392Add support for Linux/FT's bootloader, which actually uses
4393EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
4394to clear the inode.
4395
4396Add support for the "A" (no atime update) attribute. (Note: this
4397attribute is not yet in production kernels.)
4398
4399The test suite is not automatically run when doing a "make all" from
4400the top level directory. Users should manually run "make check" if
4401they wish to run the test suite.
4402
4403Upon a preenhalt(), make the printed message more explicit that
4404running e2fsck "MANAULLY" means without the -p or -a options.
4405
4406In e2fsck, if a disconnected inode is zero-length, offer to clear it
4407instead of offering to connect it to lost+found.
4408
4409In e2fsck, if a filesystem was just unmounted uncleanly, and needs
4410e2fsck to be run over it, change e2fsck to explicitly display this
4411fact.
4412
4413For dumpe2fs and e2fsck, cause the -V option to print out which
4414version of the ext2fs library is actually getting used. (This will
4415help detect mismatches of using a 1.06 utility with a 1.05 library,
4416etc.)
4417
4418Programmers' notes:
4419-------------------
4420
4421EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
4422the naming convention.
4423
4424In ext2fs_initialize(), make sure the description for the inode bitmap
4425is correctly initialize.
4426
4427Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4428
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00004429E2fsprogs 1.05 (September 7, 1996)
4430==================================
4431
4432Add support for new fields in the ext2 superblock --- volume name,
4433volume UUID, and last mounted field. Dumpe2fs displays these fields,
4434tune2fs and mke2fs allows you to set them. E2fsck will automatically
4435generate a UUID for those volumes that don't have them.
4436
4437Put in support for e2fsck to recognize HURD specific ext2 features ---
4438most notably, the translator block. The e2fsprogs tools will now use
4439the creator_os field in the superblock to correctly handle different
4440OS-specific variants of the ext2 filesystem.
4441
4442E2fsck now fixes inodes which have a the deletion time set, but which
4443have a non-zero i_link_count field by offering to clear the deletion
4444time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4445ext2 kernel behavior) and offered to unlink the file.
4446
4447If e2fsck sets the clean bit, but nothing else, set the exit code
4448FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4449set the filesystem valid bit when it was previously cleared. :-) This
4450was needed to make the HURD fsck driver happy.
4451
4452If the user refuses to attach an unattached inode, e2fsck will no
4453longer set the inode's link count. Otherwise, the inode would end up
4454getting marked as unused, which might cause loss of data later.
4455
4456Make the message issued by e2fsck when the superblock is corrupt less
4457confusing for users. It now mentions that another reason for the
4458"corrupt superblock" message might be that the partition might not be
4459an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4460
4461Make the libext2 library more robuest so that e2fsck won't coredump on
4462an illegal superblock where the blocksize is zero. (f_crashdisk is
4463the test case).
4464
4465By default, create filesystems where the default checkinterval is 6
4466months (180 days). Linux servers can be robust enough that 20 reboots
4467can be a long, long time.
4468
4469Added configure flag --enable-old-bitops, which forces the bitops to
4470use the old (native) bitmask operations. By default on the sparc
4471platform, the standard ext2 bit ordering is now used.
4472
4473Added a new feature to e2fsck to byte-swap filesystems; this can be
4474used to convert old m68k filesystems to use the standard byte-order
4475storage for the superblock, inodes, and directory blocks. This
4476function is invoked by using the '-s' option to e2fsck.
4477
4478Debugfs's "dump" command has been enhanced so that it writes out the
4479exact size of the file so that the nulls at the end of the file are
4480eliminated. The command also accept a new "-p" option which will
4481attempt preserve to preserve the ownernship, permissions, and
4482file modification/access times.
4483
4484Debugfs has two new options, -f and -R. The -R option allows the user
4485to execute a single debugfs command from the command line. The -f
4486option allows the user to specify a "command file" containing debugfs
4487commands which will get executed.
4488
4489Dumpe2fs now pretty prints the check interval, instead of just
4490printing the check interval as a number of seconds.
4491
4492Fix bugs in debugfs: the params command when no filesystem is opened
4493no longer causes a core dump. It is now possible to unlink a file
4494when a pathame containing a '/' is specified.
4495
4496Tune2fs has a new -C option which sets the number of times the
4497filesystem has been mounted.
4498
4499Fix the chattr '-v' option so that it actually works. Chattr was
4500being buggy about the -v option parsing.
4501
4502Programmers' notes:
4503-------------------
4504
4505The directory lib/uuid contains a set of library routines to generate
4506DCE compatible UUIDs.
4507
4508Extended ext2fs_namei() to handle symbolic links. Added new function
4509ext2fs_nami_follow() which will follow last symbolic link in the case
4510where the pathname points to a sym link.
4511
4512The ext2fs_block_iterate function will now return the HURD translator
4513block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4514iterator to return data blocks only. The ext2fs.h file now defines
4515constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4516BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4517count field of the iterator callback function.
4518
4519The test script driver now takes an optional second argument, which is
4520the test case to be run. This allows you to run a test case without
4521needing to run the entire test suite.
4522
4523On Linux ELF systems, install the .so files in the correct places
4524(/usr/lib). The .so files must be stored in the same directory as the
4525.a files.
4526
4527Fixed miscellaneous HURD compilation issues with header file being
4528included in the right order.
4529
4530Fixed debugfs so that it resets optind to zero, not one, since setting
4531optind to zero is more correct.
4532
4533
Theodore Ts'oa4d09611997-04-29 14:28:00 +00004534E2fsprogs 1.04 (May 16, 1996)
4535=============================
4536
4537First "official" (1.03 was a limited release only) to support building
4538e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4539kernels).
4540
4541This package includes a RPM specs file, that it can be built using the
4542RedHat Package Manager.
4543
4544E2fsck now prints a hint that if there are lots of incorrectly located
4545inode bitmaps, block bitmaps, and inode table blocks, the user might
4546want to try using e2fsck -b 8193 first, to see if that fares any
4547better.
4548
4549For ext2 filesystem written with the hurd, debugfs will now print out
4550the translator field when printing an inode structure.
4551
4552Lots of miscellaneous linking/installation cleanups:
4553
4554 Libraries are now linked using a relative pathname, instead of
4555 relying on -L working correct. It doesn't, in many cases, including
4556 current versions of GNU ld. This guarantees that the build tree is
4557 linking with the right libraries, instead of the ones installed in
4558 /usr/lib.
4559
4560 Header files, man pages, and the et/ss shell scripts are now
4561 generated using a custom substitution script, instead of relying on
4562 the configure script. This prevents needless recompilation of
4563 files; in addition, the custom substitution script is much faster.
4564
4565 e2fsck may now be linked dynamically, by using the
4566 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4567 since it increases e2fsck's dependence on other files, but some
4568 people need to save disk space, and other critical programs on their
4569 systems were being linked dynamically anyway.
4570
4571 Programs such as fsck which didn't need to be linked against
4572 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4573 only link against libraries they actually need. Otherwise, those
4574 programs would require the presense of libraries that otherwise
4575 could be removed from a rescuse diskette.
4576
4577 The ss include files are now installed correctly so they can
4578 actually be used by another package.
4579
4580 If the profiling libraries are built, they are now installed on a
4581 "make install-libs".
4582
4583
Theodore Ts'o7f88b041997-04-26 14:48:50 +00004584E2fsprogs 1.03 (March 27, 1996)
4585===============================
4586
4587Change the m68k bit numbering for bitmasks to match the bit numbering
4588used by all other ext2 implementations. (This change was requested by
4589the m68k kernel development team.)
4590
4591Support (in-development) filesystem format revision which supports
4592(among other things) dynamically sized inodes.
4593
4594Fixed a bug in the ext2 library so that an intelligent error is
4595returned if mke2fs is run with a ridiculously small number of blocks
4596for a partition.
4597
4598Fixed a bug in the ext2 library which required that the device be
4599openable in read/write mode in order to determine its size. This
4600caused e2fsck -n to require read/write access when it was not
4601previously necessary.
4602
4603Fixed a bug in e2fsck which casued it to occasionally fail the test
4604suite depending on which version of the floating point library it was
4605using.
4606
4607Fixed a bug in e2fsck so that it now halts with a fatal error when
4608certain superblock consistency checks fail. Previously it continued
4609running e2fsck, with some potential confusing/damaging consequences.
4610
4611Added new flag to fsck which allows the root to be checked in parallel
4612with other filesytems. This is not the safest thing in the world to
4613do, but some system administrators really wanted it.
4614
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00004615Fixed -Wall flames in lib/ss.
4616
Theodore Ts'o74becf31997-04-26 14:37:06 +00004617
4618E2fsprogs 1.02 (January 16, 1996)
4619=================================
4620
4621Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4622
4623Change e2fsck to print statistics of how many non-contiguous files are
4624on the system. Note that a file which is larger than 8k blocks, it is
4625guaranteed to be non-contiguous.
4626
4627In mke2fs, print a warning message if a user tries to format a whole
4628disk (/dev/hda versus /dev/hda1). If a user really wants to format a
4629whole disk, the -F (force) option forces mke2fs to format a whole disk
4630as a filesytem.
4631
4632Fix a bug in fsck where in some cases it might start checking
4633partitions in the next pass before it finishes checking partitions in
4634the current pass. This still won't cause two partitions on the same
4635disk will be checked, so it's rarely a problem in real life.
4636
4637Patch lsattr so that it won't hang when checking a named pipe.
4638
4639Minor compilation fixes:
4640 * Fix the order of libraries that were linked in debugfs.
4641 * Allow the sources to be compiled with -ansi turned on.
