2===================================
3
4Fix a potential overflow big in e2image if the device name is too
5long.
6
7Mke2fs will now create new filesystems with 256 byte inodes and the
8ext_attr feature flag by default. This allows for much better future
9compatibity with ext4 and speeds up extended attributes even on ext3
10filesystems.
11
12Teach e2fsck to ignore certain "safe" filesystem features which are
13set automatically by the kernel. Having the kernel set features
14automagically behind the user's back is a bad idea, and we should try
15to break the kernel of this habit, especially for the newer ext4
16feature flags. But for now, we will try to avoid needless full checks
17which can annoy users who are doing fresh installs.
18
19Add support in tune2fs and mke2fs for making a filesystem as being "ok
20to be used with test kernel code". This will be needed for using test
21filesystems with the latest ext4 kernel code.
22
23Change e2fsck -fD so that it sorts non-htree directories by inode
24numbers instead of by name, since that optimizes performances much
25more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
26
27If e2image fills the disk, fix it so it exits right away instead of
28spewing large numbers of error messages.
29(Addresses-Sourceforge-Feature-Request: #606508)
30
31If ftruncate64() is not available for resize2fs, let it use ftrucate()
32instead, but have it check to see if the size would get truncated, and
33skip calling ftruncate in that case.
34
35Add support for detecting HFS+ filesystems in the blkid library.
36
37Add supprt in the blkid library for ext4/ext4dev filesystems.
38
39Fix a bug in blkid where it could die on a floating point exception
40when presented with a corrupt reiserfs image.
41
42Fix blkid's handling of ntfs UUID's so that leading zeros are printed
43such that UUID string is a fixed length.
44
45Add sample python bindings for the uuid library to the contrib
46directory. (Addresses-Sourceforge-Patches: #778817)
47
48Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
49will work with large files. (Addresses Sourceforge Feature Request:
50#1257500 and Sourceforge Support Request: #1253511)
51
52Allow the debugfs 'undel' command to undelete an inode without linking
53it to a specific destination directory, since this might require
54allocating blocks that could overwrite some yet-to-be-recovered
55deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
56
57Update Swedish translations from the Translation Project.
58
59Programmer's Notes:
60-------------------
61
62Fix configure handling of --sbindir (which should rarely be used, but
63someone did complain, so let's fix it). (Addresses Sourceforge Bug:
64#498381)
65
66Updated e2fsprogs.spec file to include a new uuidd package
67
68Use pkg-config to determine where to find the devmapper library so we
69can find out where it is located on different distributions.
70
71Fix Makefile race so that "make -j3 distclean" works correctly
72
73Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
74especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
75#1819034, #1863819)
76
77Fixed spelling mistakes, typos, and otherwise clarified man pages.
78
79Fixed various Debian packaging issues --- see debian/changelog for
80details. (Addresses Debian Bugs: #459403, #459475, #459614)
81
82Remove the --enable-dynamic-static configure option, and build e2fsck
83dynamically by default. If the user wants e2fsck.static, he/she will
84need to build it via "make -C e2fsck e2fsck.static"
85
86Fix various build warnings due to missing prototypes.
87(Addresses Sourceforge Patch: #1861663, #1861659)

91====================================
92
93Improve time-based UUID generation. A new daemon uuidd, is started
94automatically by libuuid if necessary. This daemon is setuid to allow
95updates to /var/lib/libuuid, so the clock sequence number can be
96stored and so if the clock is set backwards, it can be detected.
97(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
98#233471)
99
100Filter out the NEEDS_RECOVERY feature flag when writing out the backup
101superblocks. This avoids e2fsck from concluding that a full
102filesystem check is required before backing up the superblock due to
103changes in the feature flags. (Addresses Debian Bug: #454926)
104
105Fix fsck to only treat the '#' character as a comment at the beginning
106of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
107will cause fsck to issue an bogus warning message.
108(Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
109
110Format control characters and characters with the high eighth bit set
111when printing the contents of the blkid cache, to prevent filesystems
112with garbage labels from sending escape sequences to the user's screen
113that might, for example place it in graphics mode. (Addresses Ubuntu
114Bug: #78087)
115
116Fix sign-extension problem on 64-bit systems in in the com_err
117library. (Addresses Sourceforge Bug: #1809658)
118
119Avoid division by zero error when probing an invalid FAT filesystem in
120the blkid library. (Addresses Sourceforge Bug: #1831627)
121
122Update Dutch, Polish, and Vietnamese translations from the Translation
123Project. Remove the Rwandan translation upon advice of the
124Translation Project.
125
126Programmer's Notes:
127-------------------
128
129Fix the libss "make check" regression test so that it works if the
130current directory is not in the user's path or if the libss shared
131library is not installed. (Addresses Sourceforge Bug: #1848974)
132
133Fixed spelling mistakes, typos, and otherwise clarified man pages.
134(Addresses Debian Bugs: #444883, #441872)
135
136Fixed various Debian packaging issues --- see debian/changelog for
137details. (Addresses Debian Bugs: #437720, #451172, #458017)
138
139Fix build failure on non-Linux/non-Hurd/non-Masix systems.

141
142Fix Hurd portability issues. (Addresses Debian Bug: #437720)

146===================================
147
148Fix a potential security vulnerability where an untrusted filesystem
149can be corrupted in such a way that a program using libext2fs will
150allocate a buffer which is far too small. This can lead to either a
151crash or potentially a heap-based buffer overflow crash. No known
152exploits exist, but main concern is where an untrusted user who
153possesses privileged access in a guest Xen environment could corrupt a
154filesystem which is then accessed by the pygrub program, running as
155root in the dom0 host environment, thus allowing the untrusted user to
156gain privileged access in the host OS. Thanks to the McAfee AVERT
157Research group for reporting this issue. (Addresses CVE-2007-5497.)
158
159Fix hueristics in blkid which could cause a disk without partitions to
160be incorrectly skipped when a loopback device is present. (Addresses
161Red Hat Bugzilla #400321.)
162
163Fix e2image so that in raw mode it does not create an image file which
164is one byte too large.
165
166Change mke2fs's usage message so it recommends the preferred -E option
167instead of the deprecated -R option.
168
169Enhance the blkid library so it will recognize squashfs filesystems.
170(Addresses Red Hat Bugzilla #305151.)
171
172Enhance e2fsck so it will force the backup superblocks to be backed up
173if the filesystem is consistent and key constants have been changed
174(i.e., by an on-line resize) or by e2fsck in the course of its
175operations.
176
177Enhance blkid's detection of FAT filesystems; so that USB disks with
178only a single bootable partition will not get missed.
179
180E2fsck will no longer mark a filesystem as invalid if it has time
181errors (i.e., if superblock mount time or last write time is in the
182future) and the user refuses to fix the problem.
183
184The Ubuntu init scripts don't properly set the system time correctly
185from hardware clock if the hardware clock is configured to tick local
186time instead of GMT time. Work around this as best as we can by
187providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
188be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
189Bug #131201.)
190
191Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
192Hat Bugzilla #151533.)
193
194Fix e2fsck so that if the superblock is corrupt, but still looks
195vaguely like an ext2/3/4 superblock, that it automatically tries to
196fall back to the backup superblock, instead of failing with a hard
197error.
198
199Make the e2fsprogs program more robust so that they will not crash
200when opening a corrupt filesystem where s_inode_size is zero.
201
202Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
203arguments are detected as such and the parse error is reported to the
204user. (Addresses Debian Bug #435381.)
205
206Change e2fsck so it will not complain if a file has blocks reallocated
207up to the next multiple of a system's page size.
208
209Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
210about (valid) filesystems where the inode table extends to the last
211block of the block group. (Addresses Red Hat Bugzilla #214765.)
212
213Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
214allocating inode tables for some relatively rare odd disk sizes.
215(Addresses Red Hat Bugzilla #241767.)
216
217Add Catalan translation and update Dutch and Swedish translations
218from the Translation Project.
219
220Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
221still had an issue when trying to figure out whether we need to
222byte-swap fast symlinks that contained extended attributes.
223
224Fixed spelling mistakes, typos, and otherwise clarified man pages.
225(Addresses SourceForge Bug #1821333.)
226
227
228Programmer's Notes:
229-------------------
230
231Fix mke2fs tests to avoid needing any significant ^M (CR) characters
232
233Add "make check" to the RPM spec file
234
235Fix "make install" and 'make unstall" in misc/Makefile.in so that it
236works correctly when the prefix is not the root directory.
237
238Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
239clena up after themselves by deleting the test.img temporary file
240after completing the test.
241
242Fixed a corner case bug ext2fs_unlink() when trying to delete the
243first directory entry in a directory block and the last directory
244entry in the previous directory block is not in use. Fortunately
245ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
246places where it is extremely unlikely to run into this corner case.
247
248Fix missing dependency which would cuase parallel builds to fail.
249(Addresses Sourceforge Bug #1842331.)
250
251Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
252calling open(O_CREATE) with a missing mode parameter.
253
254Fix the test_ss.c in lib/ss so it can be used as an example
255application program for the library as well as a regression test
256suite.
257
258Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
259are properly passed back up through the call stack.

Theodore Ts'od2dc78a2007-07-14 09:03:17 -0400261E2fsprogs 1.40.2 (July 12, 2007)
262================================
263
264A recent change to e2fsck_add_dir_info() to use tdb files to check
265filesystems with a very large number of filesystems had a typo which
266caused us to resize the wrong data structure. This would cause a
267array overrun leading to malloc pointer corruptions and segfaults.
268Since we normally can very accurately predict how big the the dirinfo
269array needs to be, this bug only got triggered on very badly corrupted
270filesystems.
271
272Fix a bug in e2fsck which caused it to incorrectly salvange
273directories when the last entry's rec_len is bogusly too big. This
274resulted in a nonsense filesystem corruption to be reported, and
275required a second run of e2fsck to fully fix up the directory.
276
277Update tune2fs man page to include more discussion of reserved blocks
278(Addresses Launchpad bug #47817)
279
280Update Turkish, Polish, Dutch, and Vietnamese PO files from the
281Translation Project

285===============================
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400286
287Fix bug which could cause libblkid to loop forever. When revalidating
288a partition where there is obsolete information in /etc/blkid.tab, we
289end up freeing a the type tag without clearing dev->bid_type, causing
290blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
291
292The Turkish translation has a bug in it where it has the translation
293of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
294@E, recursively, forever, until the stack fills up and e2fsck core
295dumps. We fix this by making e2fsck stop @-expansions after a
296recursive depth of 10, which is far more than we need.
Theodore Ts'od2dc78a2007-07-14 09:03:17 -0400297(Addresses Sourceforge Bug: #1646081)
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400298
299Compile the default mke2fs.conf into mke2fs program. People are
300getting surprised by mke2fs creating filesystems with different
301defaults than earlier versions of mke2fs if mke2fs.conf is not
302present. So we now create a built in version of mke2fs.conf file
303which is used by mke2fs if the /etc/mke2fs.conf is not present.
304(Addresses SourceforgeBug: #1745818)
305
306Improve the config/parse_types.sh helper script. Fix a potential
307security problem if e2fsprogs is built as root (as Gentoo does!). In
308addition fix the script and how it is called from the configure script
309so that it does the right thing when cross-compiling. (Fixes Gentoo
310bug: #146903)
311
312Update Vietnamese, French, and Dutch PO files from the Translation
313Project. Also created a new e2fsprogs.pot file for translator.
314
315Fix bogus strip permission errors when building under Debian. When
316building the e2fsprogs dpkg's, the dh_strip command emits a large
317number of error messages caused by the permissions not being right.
318So run dh_fixperms before running dh_strip.
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400319
320Programmer's Notes:
321-------------------
322
323Add new function: profile_set_default(). This function sets the value
324of the pseudo file "<default>". If the file "<default>" had
325previously been passed to profile_init(), then def_string parameter
326will be parsed and used as the profile information for the "<default>"
327file.
328
329Fix mk_cmds's error reporting so that it is unambiguous that it is the
330mk_cmds script which is generating the error. (Obviates Gentoo patch:
331e2fsprogs-1.32-mk_cmds-cosmetic.patch)
332
333Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
334priority" environment variable that overrides all others, where as
335LANG is the lowest priorty environment variable. If LC_ALL is set, it
336doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
337the all the rest are set. This will assure that the locale when
338running the test suites is the "C" locale. (Obviates Gentoo patch:
339e2fsprogs-1.38-tests-locale.patch)

343==============================
344
345Fix divide by zero error in blkid's NTFS probing logic.
Theodore Ts'od7b64722007-06-24 17:32:47 -0400346
347Add new blkid -g option which causes the blkid cache to be garbage
348collected.
349
350Fix a bug in libblkid which could cause the internal field bid_type to
351become corrupted. Fortunately bid_type isn't used much, and bid_label
352and bid_uuid is only used by debugging code, so the impact of this bug
353was very minor.
354
355Mke2fs will now store the RAID stride value when a filesystem is
356created with a requested RAID stride, and then use it automatically in
357resize2fs.
358
359Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
360isn't too big. In some cases Lustre users have tried specifying an
361inode size of 4096 bytes, while keeping an inode ratio of one inode
362per 4096 bytes.
363
364Improve sanity check in e2fsck's algorithm for finding a backup
365superblock, so that it won't accidentally find a superblock that was
366located in the journal, and then later reject it as being not a valid
367backup superblock.
368
369Fix e2fsck get_size logic so that it will work with the Linux floppy
370driver. The Linux floppy driver is a bit different from the other
371block device drivers, in that if the device has been opened with
372O_EXCL, it disallows another open(), even if the second open() does
373not have the O_EXCL flag. (Addresses Debian Bug: #410569)
374
375Fix error checking of badblock's last-block and start-block arguments.
376(Addresses Debian Bug: #416477)
377
378Fix e2fsck so that it doesn't overwrite the backup superblocks when
379recovering a journal until the master superblock has been confirmed as
380being sane.
381
382Change the blkid library to be much more paranoid about concluding
383that a partition contains an NTFS filesystem, and fetch the UUID and
384LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
385#110138)
386
387Factor out the code which sets the default journal size and move it
388into libext2fs.
389
390Enhance e2fsck so it will recreate the ext3 journal if the original
391journal inode was cleared to due it being corrupt after finishing the
392filesystem check.
393
394Fix e2fsck so that it updates the journal inode if it is corrupted and
395the backup journal information from the superblock was successfully
396used to recover the filesystem.
397
398Fix e2fsck so that it checks all of the blocks in the journal inode
399for validity. The original code only checked the direct blocks to
400make sure the journal inode was sane. Unfortunately, if some or all
401of the indirect or doubly indirect blocks were corrupted, this would
402not be caught.
403
404Add support in blkid to detect LUKS encrypted partitions.
405
406Add extra sanity checks for extended attributes in the case where the
407size is zero but the offset is very large.
408
409Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
410and ext2fs_get_next_inode_full().
411
412Clarify the copyright licenses used by the various libraries in
413the top-level COPYING file (Red Hat Bugzilla: 166058)
414
415Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
416
417Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
418
419Remove check in e2fsck which requires EA's in inodes to be sorted;
420they don't need to be sorted, and e2fsck was previously wrongly
421clearing unsorted EA's stored in the inode structure.
422
423Allow mke2fs or tune2fs to create a substantially larger journal (up
424to 10,240,000 blocks).
425
426Fix MD superblock detection, and make sure the correct UUID is
427reported from the MD superblock.
428
429Fix a signed vs. unsigned bug in debugfs.
430
431Enhance debugfs's date parser so that it accepts integer values.
432
433Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
434file with multiply claimed blocks is hard linked. or not at all if the
435root directory contains shared blocks
436
437Enhance debugfs so it can modify the block group descriptors using the
438command set_block_group_descriptor.
439
440Improve e2fsck's reporting of I/O errors so it's clearer what it was
441trying to do when an error happens
442
443Fix a bug in in how e2fsprogs byte swaps inodes containing fast
444symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
445#232663 and LTC Bugzilla: #27634)
446
447Fix potential file descriptor leak in ext2fs_get_device_size() in an
448error case.
Theodore Ts'oa0d42542007-04-07 11:05:10 -0400449
450Add libreadline.so.5 support to libss.
451
452Impove badblocks -n/-w exclusive usage message.
453
454Fix dump_unused segfault in debugfs when a filesystem is not open
455
456Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
457
458Allow the debugfs lcd command to work w/o a filesystem being open.
459(Addresses LTC Bugzilla #27513)
460
461Fix e2fsck to clear i_size for special devices with a bogus i_blocks
462field on the first pass.
463
464Fix e2fsck to set the file type of the '..' entry when connecting
465a directory to lost+found. (Addresses Lustre Bug: #11645)
466
467Enhance e2fsck to recover directories whose modes field were corrupted
468to look like special files. This is probably only useful in
469artificial test cases, but it will be useful if we ever do the "inodes
470in directory" idea for ext4.
471
472Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
473#412614)
474
475Fix resize2fs parsing of size parameter (in sector units). This was
476actually a bug in libe2p's parse_num_blocks() function. When handling
477the 's' suffix, it was ignoring the blocksize information passed in
478from the caller and always interpreting the number in terms of a 1k
479blocksize. (Addresses Debian Bug: #408298)

481There was a floating point precision error which could cause e2fsck to
482loop forever on really big filesystems with a large inode count.
483(Addresses Debian Bug: #411838)
484
485Fix memory leak in ext2fs_write_new_inode()
486
487Add support for using a scratch files directory to reduce e2fsck's
488emory utilization on really big filesystems. This uses the TDB
489library. See the [scratch_files] section of the e2fsck.conf man page
490for more details.

492Fixed type-punning bug which caused dumpe2fs to crash on the Arm
493platform (Addresses Debian Bug: #397044)
494
495Add explanatory message to badblocks that -n and -w are mutually exclusive
496(Addresses Debian Bug: #371869)
497
498Allow debugfs and dumpe2fs to support fs features under development.
499
500Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
501ext2fs_open() , which allows application to open filesystes with features
502which are currently only partially supported by e2fsprogs.
503
504Allow unix_io to support offsets greater than 2G (Addresses
505SourceForge Bug: #1547922)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400506
507Fixed overflow and signed/unsigned problems caused by the number of
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500508blocks or inodes exceeding 2**31 or being close to 2**32-1.
509
510Add support for unsigned directory hash calculations with hints in the
511superblock to fix cross-architectural portability for htree
512directories with filenames where the high 8th bit is set. (Addresses
513Debian: #389772)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400514
515Fix resize2fs so that it gives user-intelligible error messages if the
516filesystem or the kernel does not support on-line resizing.
517(Addresses Debian Bug: #380548)
518
519Require mke2fs -F -F for really dangerous operations, since -F is
520needed for less dangerous operations such as creating filesystems
521images in regular files, or creating filesystems on whole block
522devices. These relatively innocuous usages should NOT be confused
523with running mke2fs on an apparently-mounted or in-use filesystem.
524
525Allow the default inode size to be specified into the mke2fs.conf
526file.
527
528Make the smallest default journal size is big enough so that on-line
529resizing should always work.
530
531Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
532#1531372)
533
534Fix debugfs coredump when lsdel is run without an open filesystem
535(Addresses Debian Bug: #378335)
536
537Fix debugfs display bug us that bytes that have the high bit set are
538displayed as "ec" instead of "ffffffec".
539
540Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
541
542Device mapper scanning wasn't working in the blkid library because the
543pathnames had an extra "/dev" when they were being probed.
544
545Add GFS/GFS2 support to the blkid library.
546
547Fix blkid support of empty FAT filesystem labels.
548
549Avoid recursing forever (or for a long time) when the blkid library
550searches for a device and there are symlinks to directories in /dev.
551
552Avoid unaligned halfword access in blkid when accessing FAT
553superblocks, as this will cause Sparc/Solaris systems to throw a
554SIGBUS error.
555
556The latest devmapper libraries requires pthreads, add -lpthreads to
557the static link libraries for e2fsck.static if devmapper is enabled.
558(Addresses Debian bug: #388718)
559
560Improve the (non-installed, for experts only) findsuper program by
561printing the uuid and label from the superblocks, as well as the
562starting and ending offsets of the filesystem given the information in
563the superblock. Omit by default printing superblocks that are likely
564found in located in an ext3 journal unless an explicit -j option is
565given.
566
Theodore Ts'o80dda9b2007-12-03 18:33:39 -0500567Updated Spanish, French and Dutch translations and added Catalan
568translation. (Addresses Debian bug: #411562)

570Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
571determining a partition's size, since binary searching to determine
572the device doesn't work on FreeBSD.
573
Theodore Ts'od7b64722007-06-24 17:32:47 -0400574Documentation about UUID's is available in enough places, and it's
575awkward to deal with debian-legal's insanities. So I'm caving in the
576"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
577don't have do the dfsg tarball. Also remove the rule that only tried
578to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
579e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
580
581Fix the info-dir line so that the menu name does not contain a .info
582prefix. First of all, it's ugly, secondly, it causes the install-info
583command to fail to remove the com_err info file from the
584/usr/share/info/dir file when the comerr-dev package is removed and
585purged. (Addresses Debian Bug: #401711)

595Programmer's notes:
596-------------------
597
Theodore Ts'oa0d42542007-04-07 11:05:10 -0400598E2fsck now supports the %It expansion when printing a problem report.
599It will print the type of the inode in the problem context.
600
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400601Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
602(Addresses Sourceforge Bug: #1565561)
603
604Remove unused variables and other lint/gcc -Wall cleanups
605
606Add check to ext2fs_get_device_size() so it will return EFBIG for for
607filesystems contained in regular files where the filesystem image size
608is returned by stat64().
609
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500610Set local environment variables to C so mk_cmds and compile_et always
611work. (Addresses SourceForge Bug: #1532177)
612
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400613Added the 64-bit byte swapping function ext2fs_swab64().
614
615Added two new helper functions to prevent 2**31/2**32-1 overflow
616problems: ext2fs_div_ceil() and e2p_percent().
617
618Create new ext2fs library inline functions ext2fs_group_first_block()
619and ext2fs_group_last_block() in order to calculate the starting and
620ending blocks in a block group.
621
622Create the generated files read-only to remind developers not to edit them.
623
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500624Add support for autoconf 2.60 (with backwards compatibility for older
625versions of autoconf).
626
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400627Added an "make rpm" target to top-level Makefile
628
629Added various FreeBSD portability fixes.
630
631Exclude mercurial files from the RPM build tree to speed up copy/build.
632
633Use root_sysconfdir to define the locations of mke2fs.conf and
634e2fsck.conf instead of using a hard-coded /etc pathname.
635
636Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
637
638Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
639
640If diff -u is supported, use it to report test failures.
641
642Updates/improvements to RPM spec file
643
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500644Add on-disk format definitions for the following new features:
645EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
646EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
647EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
648
649Add a new make target "checked-failed" in the tests directory which
650reruns any failed tests
651
652Update draft-leach-uuids-guids-01.txt with rfc4122.txt
653
Theodore Ts'oa0d42542007-04-07 11:05:10 -0400654Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
655pointer dereferences, memory leaks, etc. None were security-criticial
656problems.
657
658Fix up usage and decrement error messages in the test_icount program
659
660Add debugging code to the com_err library; if the environment variable
661COMERR_DEBUG is set to 1, print out debugging messages as error tables
662are added and removed from the com_err library. If the
663COMERR_DEBUG_FILE environment variable is set (and the process is not
664setuid) the debugging messages may be redirected to a file.
665
666Change all of the e2fsprogs programs to use the newer add_error_table()
667and remove_error_table() interfaces instead of the much older
668initialize_*_error_table() function.
669
670Add TDB support into the ext2fs library. This allows us to have a
671guaranteed library we can count on always being present so we can
672store data in an on-disk database.
673
674Add support for using TDB to store the icount data, so we don't run out
675of memory when checking really large filesystems.
676
Theodore Ts'od7b64722007-06-24 17:32:47 -0400677Change the regression test suite so that it skips empty test directories.
678
679Define the l_i_iversion field in ext2_inode. The l_i_version field is
680now defined from the old l_i_reserved1 field in the ext2 inode. This
681field will be used to store high 32 bits of the 64-bit inode version
682number.
683
684Add Makefile production rule for e2fsprogs.spec in case it gets
685deleted.
686
687Add new function profile_get_uint() to allow for a clean way to fetch
688unsigned integers from the context.
689
690Add test to make sure the ext2 superblock structure is 1024 bytes.
691
692Fix typo in name of f_dup4 regression test
693
694Add new function blkid_gc_cache() which performs a garbage collection
695pass on the /etc/blkid.tab file.
696
697The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
698general, only e2fsck (after the filesystem is clean), tune2fs, and
699resize2fs should change the backup superblocks by default. Most
700callers of ext2fs_open() should not be touching any superblock fields
701which require the backups to be touched.
702
703Add new function to libext2fs, ext2fs_default_journal_size(), which
704returns the default journal size.

Theodore Ts'o6c094752006-05-29 11:47:25 -0400707E2fsprogs 1.39 (May 29, 2006)
708=============================
Theodore Ts'o34a26112006-03-29 20:40:23 -0500709
Theodore Ts'o34a26112006-03-29 20:40:23 -0500710Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
711between 2**31 and 2**32 blocks.
712
Theodore Ts'o34a26112006-03-29 20:40:23 -0500713Change mke2fs to use /etc/mke2fs.conf as a configuration file to
714configure the filesystem features, blocksize, and inode_ratio for
715different filesystem types.
716
Theodore Ts'o6c094752006-05-29 11:47:25 -0400717Mke2fs will now create filesystems hash trees and on-line resizing
718enabled by default, based on the new /etc/mke2fs.conf file.
719
Theodore Ts'o34a26112006-03-29 20:40:23 -0500720The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
721filesystem device node in exclusive mode to prevent accidents by
722system administrators. In the case of resize2fs and mke2fs, it will
723only use exclusive mode if the filesystem is not mounted.
724
725Fixed a bug in mke2fs which caused it to to fail when creating the
726resize inode for large filesystems. (Addresses Debian Bug #346580)
727
Theodore Ts'obae55642006-05-14 17:31:48 -0400728When allocating space for the RAID filesystems with the stride
729parameter, mke2fs will now place each portion of the group's inode
730table right up after the superblock (if present) in order to minimize
731fragmentation of the freespace.
732
733Speed up mke2fs and e2fsck by writing inode and block bitmaps more
734efficiently by writing the inode and block bitmaps in one pass, thus
735reducing the number of disk seeks required.
736
Theodore Ts'o34a26112006-03-29 20:40:23 -0500737Add support for on-line resizing to resize2fs.
738
739Fix blkid library so that logic to determine whether or not a device's
740cached information in /etc/blkid.tab needs to be verified or not
741doesn't get confused by a system clock which is insane (for example,
742if the battery is dead on a Macintosh running PPC Linux. (Addresses
743Red Hat Bug: #182188)
744
745The blkid library will now store the UUID of the external journal used
746by ext3 filesystems, so that in the future, the userspace mount binary
747can use this to find the location of the external journal and pass
748this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -0500749
750E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -0500751control how various options should be handled. See the e2fsck.conf
752man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -0500753
Theodore Ts'o34a26112006-03-29 20:40:23 -0500754E2fsck now prints an explanatory message when delaying a filesystem
755check when the system is running on battery. (Addresses Debian Bug:
756#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400757
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500758E2fsck will detect if the superblock's last mount field or last write
759field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -0500760#327580) These problems will be fixed automatically in preen mode
761since Debian's boot sequence bogusly doesn't set the time correctly
762until potentially very late in the bootup process, and this can cause
763false positives which will cause users' systems to fail to boot.
764(Addresses Debian Bugs #343662 and #343645)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400765
Theodore Ts'o34a26112006-03-29 20:40:23 -0500766E2fsck now checks to see if the superblock hint for the location of
767the external journal is incorrect, and if so, offer to update it.
768(Addresses Debian Bug: #355644)
769
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400770Fix e2fsck from segfaulting on disconnected inodes that contain one or
771more extended attributes. (Addresses Debian Bug: #316736, #318463)
772
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500773E2fsck will stop and print a warning if the user tries running a
774read/write badblocks test on a read-only mounted root filesystem.
775
Theodore Ts'obae55642006-05-14 17:31:48 -0400776Fix a memory leak in e2fsck's error paths. (Thanks to Michael
777C. Thompson for pointing these out; they were originally found using
778Coverity.)
779
Theodore Ts'of3227852005-12-31 16:45:29 -0500780When resizing a file containing a filesystem, resize2fs will expand or
781truncate a file as necessary. (Addresses Debian Bug: #271607)
782
Theodore Ts'obae55642006-05-14 17:31:48 -0400783Resize2fs will now automatically determine the RAID stride parameter that
784had been used to create the filesystem, and use that for newly created
785block groups. The RAID stride parameter may also be manually specified
786on the command line using the new -S option to resize2fs.
787
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500788Fix mke2fs so that it correctly creates external journals on
789big-endian machines (such as a S/390).
790
Theodore Ts'obae55642006-05-14 17:31:48 -0400791Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
792fail to print out the journal or hash seed UUID. (Thanks to Guillaume
793Chambraud for pointing this out.)
794
795Dumpe2fs will now print the size of the journal (if present).
796
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500797Fix debugfs's set_inode_field command so it can properly set the frag,
798fsize, uid_high, gid_high, and author fields in the inode instead of
799silently failing, and so that setting the i_size actually sets i_size
800correctly.
801
802Add a new debugfs command, set_current_time, which sets fs->now so
803that regression test suites can repeatedly modify the filesystem's
804last_write fields.
805
Theodore Ts'o34a26112006-03-29 20:40:23 -0500806Fix a bug in debugfs's icheck which would incorrectly report the owner
807of an extended attribute block.
808
Theodore Ts'obae55642006-05-14 17:31:48 -0400809Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
810print a usage message when an illegal option character is given.
811
Theodore Ts'o6c094752006-05-29 11:47:25 -0400812Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
813so it won't core dump. (Addresses SourceForge bug #1424311)
814
Theodore Ts'obae55642006-05-14 17:31:48 -0400815Fix mklost+found so that it creates a full-sized directory on
816filesystems with larger block sizes.
817
818Fix a file descriptor leak in blkid library.
819
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500820Fix a display bug in "badblocks -sv" so that the done message properly
821clears the block number at the end of the test. (Addresses Debian Bug
822#322231)
823

825(Addresses Debian Bug: #80205)
826
827Use fstat/fstat64 in getsize.c if the the target is a regular file,
828instead of attempting to do a binary search. Fix some fd leaks in
829error cases.
830
Theodore Ts'o34a26112006-03-29 20:40:23 -0500831Add support for device mapper library to the blkid library to ensure
832that the "best" (i.e., leaf) device is probed by the blkid library.
833
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500834Fix the blkid library so that it notices when an ext2 filesystem is
835upgraded to ext3.
836
837Improve the blkid's library VFAT/FAT detection; it now understands
838labels stored in the root directory, and is more paranoid about
839checking the FAT superblock values.
840
Theodore Ts'o34a26112006-03-29 20:40:23 -0500841Fixed a fd leak in the uuid library which was causing problems for the
842LVM tools. (Addresses Debian Bug: #345832)
843
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500844Add support for the reiser4 and software suspend partitions to the
845blkid library. Also add support for extract the label from iso9660
846filesystems.
847
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400848Fix a compile_et bug which miscount the number of error messages if
849continuations are used in the .et file.
850
851Add extra sanity checks to protect users from unusual cirucmstances
852where /etc/mtab may not be sane, by checking to see if the device is
853reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
854#319002)

861
Theodore Ts'o34a26112006-03-29 20:40:23 -0500862Fixed spelling mistakes, typos, and otherwise clarified man pages and

873Programmer's notes:
874-------------------
875
Theodore Ts'o7e2ec012006-04-22 04:29:16 -0400876Update config.guess and config.sub to latest version (2006-02-23) from
877FSF.
878
879Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
880Bugs: #360661, #360317)
881
Theodore Ts'o34a26112006-03-29 20:40:23 -0500882Fixed the Makefile so that they work correctly on newer versions of
883GNU make (i.e., 3.81).
884
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400885Add valgrind support to the regression test suites, and eliminate
886false positives from valgrind.
887
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500888Add a regression test suite for the blkid library.
889
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400890Fix a fencepost error in resize2fs caught by valgrind.
891
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500892Fix compiler warnings about missing memcpy prototypes.
893
894We no longer have the sparc assembly code in the header file any more,
895so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
896break compiles on the sparc architectures when using gcc.
897
898In the libext2fs library, add the new field fs->now which if non-zero
899is used instead of the system time when setting various filesystem
900fields (last modified time, last write time, etc.)
901
902Fix gcc 4.01 complaints by adding a missing #include <string.h> to
903ext2fs.h which is needed since the inline functions use memcpy().
904(Addresses Sourceforge Bug #1251062)
905
906Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
907the build system when building files in the util directory which are
908needed during the build process. This avoids potential problems when
909cross-compiling and some of the options specified in CFLAGS or LDFLAGS
910are not recognized as valid by the host compiler. (Addresses
911Sourceforge Bug #1261547)
912
913Clean up the blkid library by making the superblock and generic i/o
914functions to be more generic. Clean up interface to the probe
915function, and fix memory leak. Finallly, remove an unneeded reference
916to probe.h in the lib/blkid/resolve.c
917
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500918Add an ext2fs_read_bb_FILE regression test to confirm proper detection
919of invalid block #'s.
920
Theodore Ts'o34a26112006-03-29 20:40:23 -0500921The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
922indicate that the the function read/writes the memory location.
923
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500924Fix various gcc -Wall complaints.
925
926Add a dependency to make sure that the subdirectories are created
927before creating all of the object files, in order to address parallel
928build problem in the library Makefiles. (Addresses Sourceforge Bug:
929#1261553)
930
931Add $(LDFLAGS) to the command line argument when generating an ELF or
932Solaris shared library, to allow cross-compile and other builds that
933might need to specify -L paths to needed libraries. (Addresses
934Sourceforge Bug #1261549)
935
Theodore Ts'obae55642006-05-14 17:31:48 -0400936Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
937intended for testing purposes. It allows an ext2/ext3 developer to
938create very large filesystems using sparse files where most of the
939block groups are not initialized and so do not require much disk
940space. Eventually it could be used as a way of speeding up mke2fs and
941e2fsck for large filesystem, but that would be best done by adding an
942RO_COMPAT extension to the filesystem to allow the inode table to be
943lazily initialized on a per-block basis, instead of being entirely
944initialized or entirely unused on a per-blockgroup basis.
945
Theodore Ts'o6c094752006-05-29 11:47:25 -0400946Fix backwards compatibility so e2fsprogs will better compile on Linux
9472.0.35 systems.
948
949Make test scripts more robust against locale-related environment variables
950
951Fix type warning problem with sizeof() in ext2fs_open2().
952
953Fix type warning problem with time_t in debugfs.
954
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400955
Theodore Ts'ofea95ff2005-07-01 17:31:55 -0500956E2fsprogs 1.38 (June 30, 2005)
Theodore Ts'o1f965c82005-06-30 20:06:45 -0400957==============================
958
959Fix blkid's test programs (built with "make check") compile correctly
960even without "configure --enable-blkid-debug".
961
962Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
963type aliasing rules on newer gcc compilers. (Addresses Red Hat
964Bugzilla ##161183.)
965
966Fix com_err library to make it more compatible with recent changes
967made to the com_err library in MIT Kerberos V5 version 1.4.
968(Addresses Sourcefroge Bug #1150146)
969
970General cleanup of messages printed by e2fsprogs programs for grammar,
971consistency, and to make life easier for translators. Fixed a few
972strings containing English that had not been marked as needing
973translations. Removed strings that do not need to be translated, to
974make life easier for translators.
975
976Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
977test to see if a device appears to be in use instead of just relying
978on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
979
980Fix portability problem in the filefrag program affecting platforms
981where the size of an integer is smaller than the size of a long.
982(Addresses Debian Bug #309655)
983
984Mke2fs will now use a larger journal by default for filesystems
985greater than 4GB. (128 MB instead of 32MB).
986
987Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
988unless forced. This is to avoid signed vs. unsigned kernel bugs in
989block numbers that still need to be fixed.
990
991The blkid program has a new option which will more efficiently search
992for device when it is known (or expected) that only one matching
993device will be found in the system, such as when doing a lookup by
994UUID.
995
996Debian's e2fsprogs-specific initrd fragment will avoid including
997unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
998and LD_LIBRARY_PATH, and filtering out libraries found in
999/etc/ld.so.preload. (Addresses Debian Bug: #304003)
1000
1001Fixed a potential portability issue in the blkid programs for
1002architectures where the char type is unsigned. (Addresses Sourceforge
1003Bug: #1180585)
1004
1005Fix a bug in filefrag so that it doesn't falsely count an extra
1006discontinuity when the first block found is an indirect block.
1007(Addresses Debian Bug #307607).
1008
1009Fix blkid's recognition of cramfs filesystems, and enhance it to be
1010able to handle cramfs labels.
1011
1012Fix debugfs's stat command to not core dump when a filesystem is not
1013open.
1014
1015Fix e2fsck's handling of error conditions caused by the resize inode
1016claiming blocks that are also used by other inodes, a filesystem
1017corruption which was commonly caused by a bug in Fedora Core 3's
1018resize2fs program.
1019
1020Fixed bug in filefrag which caused it to fail on non-ext2/3
1021filesystems. (Addresses Debian Bug: #303509)
1022
1023If the superblock last mount time indicates that the system clock may
1024not be accurate, then e2fsck will omit checking inodes' deletion time
1025field for indications of a potential corrupted orphaned inode list.
1026(Previously e2fsck only ommited these LOW_DTIME checks when the
1027superblock's last write time looked insane.)
1028
1029Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
1030(Addresses Debian bug #302200)
1031
1032Make the blkid library more paranoid about being run from setgid
1033programs, and to use __secure_getenv() from libc if it is available.
1034
1035Fixed spelling mistakes, typos, and otherwise clarified man pages.
1036(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
1037and Sourceforge Bug: #1189803)
1038
1039Updated and fixed translations.
1040
1041Fixed various Debian packaging issues --- see debian/changelog for
1042details.
1043
1044Programmer's notes:
1045-------------------
1046
1047Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
1048changed to take an unsigned int for the bit number. Negative bit
1049numbers were never allowed (and didn't make any sense), so this should
1050be a safe change. This is needed to allow safe use of block numbers
1051greater than or equal to 2**31.
1052
1053The compile_et program will avoid recreating generated foo_err.c and
1054foo_err.h files if no changes are necessary. The compile_et program
1055will also atomically replace these files to avoid a potential parallel
1056build race problem on SMP systems. (Addresses Sourceforge Bug:
1057#1157933)
1058
1059Added a new function to the blkid library, blkid_probe_all_new(),
1060which only probes newly added disk devices, and change
1061blkid_find_dev_with_tag() to use this function so that when a
1062requested tag is not found, devices that were previously not checked
1063are searched before searching all devices in the system.
1064
1065Added new functions to the blkid library, blkid_dev_set_search() and
1066blkid_dev_has_tag().
1067
1068E2fsck's problem strings can now use @m and @n as abbrevations for
1069"multiply-claimed" and "invalid", respectively.
1070
1071The e2fsprog.pot file now has an explanation of how the @-expansion
1072and %-expansion works, and strings in e2fsck/problem.c which contain @
1073characters now have comments in e2fsprogs.pot with the @-expansion to
1074make life easier for translators.
1075
1076Fixed missing return values in the ext2fs library which could cause it
1077to return random garbage in certain error conditions.
1078
1079Allow the current time to be overriden via the E2FSCK_TIME environment
1080variable for use in regression tests.
1081
1082The test scrpit driver program now exits with a non-zero status if
1083there any of its test that it ran failed.
1084
1085Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
1086Bug: #1157933)
1087
1088Fixed "make check" so that it compiles correctly even when e2fsprogs'
1089header files have not be installed in the system include directories.
1090(Addresses Sourceforge Bug: #1180572)
1091
1092Fixed gcc -Wall nits.

1094
Theodore Ts'ofd4b28e2005-03-21 22:37:03 -05001095E2fsprogs 1.37 (March 21, 2005)
1096===============================
1097
1098Add support for checking the validity of Extended Attributes stored in
1099inodes to e2fsck.
1100
1101Add support for dumping the contents of large inodes to debugfs,
1102including the extended attributes stored in inodes.
1103
1104Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1105when we create a new inode we make sure that the extra information in
1106the inode (any extra fields in a large inode and any ea-in-inode
1107information) is initialized correctly. This can take place when
1108mke2fs creates the root and lost+found directory, when e2fsck creates
1109a new root inode or a new lost+found directory, and when the user uses
1110the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1111create inode could inherit garbage (or old EA information) from a
1112previously deleted inode.
1113
1114Fixed a bug in e2fsck so it would notice if a file with an extended
1115attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1116to zero.
1117
1118Added support to filefrag to detect files which are using the new
1119experimental file extents format, and use the non-ext2 algorithm in
1120that case. Fixed a bug to avoid reporting a false discontinuity if
1121there is one or more unallocated blocks at the beginning of a file.
1122
1123Duplicated a check for noticing whether or not the number of blocks
1124(given a certain blocksize) is greater than 2**32 when the
1125BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1126allows mke2fs to automatically use a larger blocksize when creating a
1127filesystem on a very large device when run on systems that do not
1128support BLKGETSIZE64.
1129
1130Fix the I18N build which was broken in e2fsprogs 1.36 because the
1131build system had been switched to treat the .gmo files as shipped
1132files (for backwards compatibility with systems that have older GNU
1133I18N tools installed), but the gen_tarball.in script was still
1134removing the .gmo files from the official source distribution.
1135
1136Fixed various Debian packaging issues --- see debian/changelog for
1137details. (Addresses Debian Bugs ##296769, #299341)
1138
1139Programmer's notes:
1140-------------------
1141
1142Added new functions to the e2p library which convert between a string
1143and os_type: e2p_os2string() and e2p_string2os(), and used them to
1144make the generated binaries more compact.
1145
1146Fixed a compile-time error on Darwin systems.
1147
1148Cleaned up the lib/ext2fs Makefile slightly.
1149
1150
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001151E2fsprogs 1.36 (February 4, 2005)
1152=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001153
1154All of the patches that were applied to Fedore Core 3's
1155e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1156lot of bug fixes first. Users of Fedora Core 3 are strongly
1157encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1158
1159Add support for filesystem with the online resizing via resize inode
1160feature. Fixed numerous bugs from the Fedora patches. The Fedora
1161patches also didn't bother to do any consistency checking on the
1162resize inode, or add any tests to the regression test suite. The "-R
1163resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1164being listed in mke2fs's usage message. All of these shortcomings
1165have been corrected.
1166
1167E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1168program. In order to do this, the user must run the commands:
1169
Theodore Ts'od0a3b462005-05-05 22:57:44 -04001170 debugfs -w /dev/hdXXX -R "features ^resize_inode"
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001171 e2fsck -f /dev/hdXXX
1172
1173Optionally, the ext2prepare command can be used to re-enable online
1174resizing after the filesystem has been fixed.
1175
1176The fsck program will now accept an optional filedescriptor argument
1177to the -C option. (The Fedora version of this patch would sometimes
1178cause fsck to ignore a parameter on fsck's command line in some rare
1179cases, sigh.)
1180
Theodore Ts'odc256972005-01-26 13:20:12 -05001181Make sure e2fsprogs doesn't write garbage into the reserved portion of
1182large inodes.
1183
1184Make sure resize2fs releases the blocks belonging to the old inode
1185table blocks when moving the inode table. (Addresses Debian Bug:
1186#290894)
1187
1188Skip the r_resize_inode test if resize2fs is not compiled (due to
1189configure --disable-resizer)
1190
1191E2fsck now checks the summary filesystem accounting information, and
1192if any of the information is obviously wrong, it will force a full
1193filesystem check. (Addresses Debian Bug #291571)
1194
1195Fix e2fsck to not complain when the resize_inode feature is enabled,
1196s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1197the resize inode.
1198
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001199Fix e2fsck to note delete symlinks that contain an extended attribute
1200after the ext_attr feature flag has been cleared. (Addresses Red Hat
1201Bugzilla #146284).
1202
Theodore Ts'odc256972005-01-26 13:20:12 -05001203Add new utility program, copy_sparse.c, which is very useful
1204for dealing with large sparse files (such as e2image files).
1205
1206Add support for jnl_blocks[] for debugfs's set_super_value.
1207
1208Fix filefrag so that it works correctly with sparse files.
1209
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001210Filefrag -v will print first and last blocks.
1211
Theodore Ts'odc256972005-01-26 13:20:12 -05001212Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1213and dumpe2fs.
1214
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001215Add mke2fs support so that it can support filesystems larger than 4TB
1216automatically, by retrying with a 4k blocksize if the device size is
1217too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1218bug #1106631)
1219
Theodore Ts'odc256972005-01-26 13:20:12 -05001220Change blkid to test for NTFS first because Windows sometimes doesn't
1221clear enough of the parition to confuse the probing routines into
1222thinking the old filesystem type is still valid. (Addresses Debian
1223Bug #291990)
1224
Theodore Ts'o66fa0de2005-01-11 14:39:55 -05001225Add support for swap partition label and uuid's in the blkid library.
1226
Theodore Ts'odc256972005-01-26 13:20:12 -05001227Add support to the blkid library to recognize Oracle ASM volumes.
1228
1229Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001230not just the first one, and work more consistently when the blkid
1231cache file is not available or set to /dev/null. (Addresses Debian
1232Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -05001233
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001234Badblocks will now correctly display block numbers greater than
1235999,999,999 in its progress display.
1236
1237The tune2fs program will not allow the user from setting a ridiculous
1238number of reserved blocks which would cause e2fsck to assume the
1239superblock was corrupt. E2fsck's standards for what is a ridiculous
1240number of reserved block has also been relaxed to 50% of the blocks in
1241the filesystem.
1242
1243The blkid library will return vfat in preference to msdos, and ext3 in
1244preference to ext2 (if the journalling flag is set) so that mount will
1245do the right thing. (Addresses Debian bug #287455)
1246
1247Mke2fs will now use the -E option for extended options; the old -R
1248(raid options) option is still accepted for backwards compatibility.
1249Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1250
1251Mke2fs will now accept a size in megabytes, gigabytes, and other units
1252(via "32m" or "4g" on the command line) if the user finds this more
1253convenient than specifying a block count.
1254
1255Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1256cache conherency problem.
1257
1258Debugfs now supports a new command, set_inode_field, which allows a
1259user to manually set a specific inode field more conveniently, as well
1260as set entries in the indirect block map.
1261
1262Debugfs's set_super_value command has been enhanced so that the user
1263can set most superblock fields, including the date/time fields and
1264some of the more newsly added superblock fields.
1265
1266E2fsprogs programs now accept an offset to be passed to the file
1267specifiers, via the syntax: "/tmp/test.img?offset=1024".
1268
1269E2fsprogs programs will now accept blocksizes up to 65536; kernel
1270support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001271other architectures with page sizes greater than 4k. There are 2.6
1272kernel patches out there which enable this, but they are of this
1273writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001274
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05001275The e2image command now takes the -s option which will scramble
1276directory entries for raw image files.
1277
1278Fix a file descriptor leak in the filefrag program.
1279
1280Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1281present.
1282
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001283Fix bug in debugfs where kill_file would lead to errors when deleting
1284devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1285
1286Fix bug in the blkid library when detecting the ocfs1 filesystem
1287
1288Remove obsolete EVMS 1.x and a.out DLL support.
1289
1290E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -04001291
1292Fixed two potential ordering constraint problems in e2fsck which might
1293cause the filesystem to be corrupted if e2fsck is interrupted during a
1294(extremely narrow) race window. Thanks to Junfeng Yang from the
1295Stanford Metacompilation group for pointing this out.
1296
1297Fixed bug in e2fsck where it would not accurately detect whether or
1298not the system is running on adaptor if the ACPI device representing
1299the AC adapter didn't correspond to the what was used on IBM
1300Thinkpads.
1301
1302Change e2fsck to accept directories greater than 32MB.
1303
1304Fix e2fsck so that a checkinterval of zero disables a time-based check
1305of the filesystem.
1306
1307Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
1308to the PAGER environment variable. (Addresses Debian Bug #239547)
1309
1310Tune2fs will not mark rewrite the superblock if the feature bitmasks
1311are not modified.
1312
1313The debugfs program will set the filetype information when creating a
1314link.
1315
1316Add debugfs -d option to use a separate source of data blocks when
1317reading from an e2image file.
1318
1319Add e2image -I option which allows the e2image metadata to be
1320installed into a filesystem.
1321
1322Fixed bug in the badblocks program which caused "done" to always
1323appear in english even when a translation was available. (Addresses
1324Debian Bug #252836)
1325
1326The blkid program has a new option -o which controls the output format
1327of the blkid program; this is makes blkid more convenient to use in
1328shell scripts.
1329
1330Fix a minor bug in uuid library, which was not using the full 14 bits
1331of clock sequence when generating UUID's.
1332
1333Fix a Y8.8888K problem in the uuid library.
1334
1335Logsave now creates a new session id for itself to avoid getting
1336killed by init whan transitioning between init levels.
1337
1338Change the licensing of the UUID library to be the 3-clause BSD-style
1339license; this allows Apple to use the uuid library in Darwin.
1340
1341Add ocfs and ocfs2 probe support into the blkid library.
1342
1343Fix a memory and file descriptor leak in the blkid library.
1344
1345The blkid library will revalidate the device if the system time is
1346earlier than last verification time of the device, since that
1347indicates that the system time is probably nottrustworthy.
1348
1349The blkid library will override the default location of the blkid.tab
1350file by the BLKID_FILE environment variable, if it is available.
1351
1352Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
1353
1354Add various portability fixes for lame new versions of glibc, Darwin
1355and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001356Bugs #239934, #264630, #269044, #255589, #289133)
1357
1358Add support for Windows 9x/NT under Cygwin.
Theodore Ts'o48301122004-09-19 08:23:41 -04001359
1360Updated and clarified various man pages. (Addresses Debian Bugs #236383,

Theodore Ts'o48301122004-09-19 08:23:41 -04001362
1363Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
1364
1365Update the rpm spec files so that it works better with Fedora core 2
1366and RH9.
1367
1368Fixed various Debian packaging issues (see debian/changelog). In
1369particular, fixed the Debian initrd scripts. (#241183, #248050,
1370#253595, #247775)

1373Programmer's notes:
1374-------------------
1375
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001376Fixed various gcc -Wall warnings.
Theodore Ts'o48301122004-09-19 08:23:41 -04001377
1378The uuid library now has new functions uuid_unparse_upper() and
1379uuid_unparse_lower() which forces the case of the hex digits to be
1380upper case, or lower case.
1381
1382The build process has been speeded up by enhancing the subst program
1383to update the modtime on the generated files even when the generated
1384file hasn't changed.
1385
1386The uuid library now uses C99 stdint.h types instead of custom types.
1387
1388Updated config.guess and config.sub with newer versions from the FSF.
1389
1390Removed out of date .cvsignore files from the source distribution.
1391
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001392The ext2fs_unlink() function will return an error if both the name and
1393inode number are unspecified, to avoid doing something surprising
1394(such as unconditionally deleting the first directory entry).
1395Directory entries are now deleted by coalescing them with the previous
1396directory entry if possible, to avoid directory fragmentation. This
1397is not an issue with the e2fsprogs suite, but may be a problem for
1398some of the users of libext2fs, such as e2tools.
1399
1400Add support for version numbers of the form "1.36-rc1".
1401
Theodore Ts'o48301122004-09-19 08:23:41 -04001402Fix build of mke2fs.static.
1403
Theodore Ts'odc256972005-01-26 13:20:12 -05001404Add basic ext2fs library support for large (EA in inode) inodes.
1405
Theodore Ts'o48301122004-09-19 08:23:41 -04001406The test_io mechanism can now abort after n reads or writes to a
1407particular block. The block is specified by TEST_IO_BLOCK environment
1408variable, and the read/write count by the TEST_IO_READ_ABORT and
1409TEST_IO_WRITE_ABORT environment variables. The block data is now only
1410dumped if the 0x10 bit is set in TEST_IO_FLAGS.
1411
1412UUID_DEFINE() in the uuid library now creates a static variable, with
1413__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
1414be used in header files.
1415
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001416Add support for the install-strip and install-shlibs-strip targets, as
1417suggested by the GNU coding guielines. "make install" no longer
1418strips the binaries which are installed.
1419
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001420Remove support for the --enable-old-bitops configure option which was
1421only for very old sparc systems.
1422
1423Remove support for --enable-clear-htree; this was only needed during
1424the early development of the htree patch.
1425
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001426Use Linux-kernel-style makefile output so it is easier to see compiler
1427warnings.
1428
1429Update gettext files to version 0.14.1.
1430
1431Update to use autoconf 2.5x.
1432
1433Improved support for compiling e2fsprogs under dietlibc.
1434
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05001435Make e2fsprogs portable to Solaris and FreeBSD systems.
1436
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001437Add blkid_verify(), blkid_get_library_version(), and
1438blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -05001439
1440Add pkg-config files for e2fsprogs's libraries.
1441
1442Fix "make uninstall" to so that it removes everything that is installed.
1443
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001444Add a configure --enable-maintainer-mode option which enables the
1445makefile rules to rebuild the configure script from configure.in, and
1446to reubuild the .gmo files in po directory.
1447
1448Drop the sparc assembly bitwise operations; it's less efficient
1449than the GCC 3.4 compile code and triggers compiler warnings on
1450sparc64. Thanks to Matthias Andree for his analysis and suggestions.

Theodore Ts'ob70b1162004-02-28 10:52:35 -05001454E2fsprogs 1.35 (February 28, 2004)
1455==================================
1456
Theodore Ts'o48301122004-09-19 08:23:41 -04001457E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001458preserves the existing badblocks list.
1459
Theodore Ts'o48301122004-09-19 08:23:41 -04001460Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001461
1462E2fsprogs will now deal correctly with symlinks that contain
1463extended attribute information, which can be created using SE Linux.
1464(Addresses Debian Bug #232328)
1465
1466Remove a double longjump into an invalid stack frame bug in e2fsck.
1467(This was during an abort sequence, which normally worked on Linux and
1468caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001469
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001470Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
1471(the NLS library will replace "" with the .po header information).
1472
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001473Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
1474dump due to a division by zero error. (Addresses Debian bug #207082)
1475
Theodore Ts'o151a7162003-12-26 14:04:33 -05001476Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
1477when reconnecting a directory requires creating a lost+found
1478directory. (Addresses Debian bug #219640).
1479
1480Fixed a bug where e2fsck would bomb out if a journal needed to be
1481replayed when using an alternate superblock.
1482
Theodore Ts'o48301122004-09-19 08:23:41 -04001483E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001484if the laptop is running on battery. The next time fsck runs while
1485the system is on the AC mains, or after the grace period is exceeded,
1486the filesystem will be checked. (Addresses Debian bug #205177)
1487
1488E2fsck will inform the user when there are 5 or fewer mounts before a
1489filesystem check will be forced. (Addresses Debian bug #157194)
1490
1491Fix e2fsck's handling of corrupted indirect blocks in the bad block.
1492We now correctly handle the case where there is an overlap between a
1493block group descriptor or a superblock and a bad block indirect block.
1494In the case where the indirect block is corrupted, we now suggest
1495"e2fsck -c".
1496
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001497Fix byte swap bugs in e2fsck that caused the journal backup location
1498in the superblock and symlinks created by SE Linux to be cleared
1499by e2fsck on big-endian machines. (Addresses Debian bug #228723)
1500
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001501E2fsck -c now replaces the current list of bad blocks with the ones
1502found by badblocks.
1503
1504Fix bugs in e2fsck and tune2fs which could cause a core dump if a
1505non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
1506
1507Fix a potential bug in e2fsck which could cause it to core dump when
1508trying to print the location of the backup superblock.
1509
1510Protect against a potential core dump in e2fsck when printing a
1511message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001512
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001513Add support for backing up the journal inode location in the
1514superblock. E2fsck will automatically save the journal information in
1515the superblock if it is not there already, and will use it if the
1516journal inode appears to be corrupted. ext2fs_add_journal_inode()
1517will also save the backup information, so that new filesystems created
1518by mke2fs and filesystems that have journals added via tune2fs will
1519also have journal location written to the superblock as well.
1520Debugfs's logdump command has been enhanced so that it can use the
1521journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001522
1523E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001524
1525Shrink the size of the e2fsck executable by moving some initialized
1526variables to the BSS segment.
1527
1528E2fsck will avoid printing the ^A and ^B characters which bracket the
1529progress bar when stdout and stdin are a tty device instead of a pipe
1530to another program. (Addresses Debian bug #204137)
1531
Theodore Ts'o151a7162003-12-26 14:04:33 -05001532Debugfs's mkdir command will automatically expand the directory if
1533necessary. (Addresses Debian Bug: #217892)
1534
1535Fixed a bug in debugfs so that copying a file from /dev/null uses the
1536correct mode bits. (Addresses Debian Bug: #217456)
1537
1538If the environment variables DEBUFS_PAGER and PAGER are not set,
1539debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -05001540/usr/bin/pager, and then falling back to 'more' and 'less'.
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001541(Addresses Debian bug #221977)
1542
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001543Debugfs will now support 2.6 device numbers where the major or minor
1544number may be larger than 255. (Addresses Sourceforge bug #865289)
1545
Theodore Ts'o48301122004-09-19 08:23:41 -04001546Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
1547
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001548Chattr now stops processing options when it sees '--'. (Addresses
1549Debian bug #225188)
Theodore Ts'o151a7162003-12-26 14:04:33 -05001550
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001551Fix regression tests so they work correctly when e2fsprogs is compiled
1552with configure --disable-htree.
1553
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001554Fix bug in uuid library when there is no network card and the library
1555is generating a time-based uuid. The random MAC address was not
1556correctly generated to be a multicast address.
1557
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001558Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -04001559around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001560
1561Fix bug in badblocks when using O_DIRECT; we need to make sure that
1562we're reading from an offset which is page aligned. For read-only and
1563read-write tests, we try to recover after an error so that we can
1564continue reading on page-aligned boundaries. (Addresses Debian Bug
1565#203713)
1566
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001567Badblocks now checks 64 blocks at a time instead of 16. (Addresses
1568Debian bug #232240)
1569
Theodore Ts'o151a7162003-12-26 14:04:33 -05001570Updated and clarified various man pages. (Addresses Debian Bug

1577Programmer's notes:
1578-------------------
1579
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001580Fixed a build problem so that e2fsprogs would compile with the
1581--enable-profile option to configure selected. (Addresses Sourceforge
1582bug #811408)
1583
1584Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
1585Bugzilla Bug #112448)
1586
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001587Centralize code which calculates the location of the superblock
1588and block group descriptors so that it is in a single library routine.
1589
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001590Added two new functions, ext2fs_file_open2() and
1591ext2fs_inode_io_intern2() which take a pointer to an inode structure.
1592
1593Fix compile_et to output the correct prototype for
1594initialize_xxx_err_table_r() in the header file. (Addresses Debian
1595bug #204332)
1596
1597In the lib/et makefile, make sure com_err.info is deleted on "make clean".
1598
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001599Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
1600present. This is for when we try stuffing an int into void * pointer.
1601
1602Fix type-punning which can cause gcc 3.x to miscompile code by getting
1603confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
1604and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
1605**'. The EVMS code uses an ugly union approach since we don't want to
1606modify the EVMS interfaces.
1607
1608Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
1609aid build process on systems can use invoke GNU make as "gmake".
1610
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001611Added regression testing for mke2fs.
1612
1613Fixed gcc -Wall nitpicks.
1614
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001615Fixed various compiler warnings.
1616
1617Add portability fixes for FreeBSD and for using fsctl under Darwin to
1618support ext2 ioctl's.

Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001621E2fsprogs 1.34 (July 25, 2003)
1622===============================
1623
1624Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
1625a tight loop while waiting for a child fsck to exit in some cases.
1626This burns CPU times which slows down the low-level filesystem check.
1627
1628Added code to mke2fs to assure that the default block size for a
1629filesystem is at least as big as the sector size of the device, if it
1630can be determined.
1631
1632Changed mke2fs and resize2fs to round the default size of a filesystem
1633to be an even multiple of the VM pagesize in order to avoid a Linux
1634kernel bug introduced when the storage of the buffer cache was moved
1635into the page cache.
1636
1637Mke2fs will warn the user when creating a filesystem with journaling
1638and a blocksize greater than 4096. (Addresses Debian bug #193773)
1639
1640Fixed a bug in resize2fs which caused it to fail on filesystems with a
1641non-empty bad block list. Resize2fs now discards any blocks on the
1642badblock list which are no longer part of the filesystem as the result
1643of a filesystem shrink. (Note: this means that shrinking and then
1644enlarging a filesystem is no longer a reversible operation;
1645information about bad blocks in the part of the filesystem which is to
1646be chopped off will be lost.)
1647
1648Changed resize2fs so the user can use prefixes to specify the units of
1649the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
1650and to make the error and informational messages explicitly display
1651the blocksize used by the filesystem, in order to avoid confusion.
1652(Addresses Debian bug: #189814)
1653
1654Added a new debugfs command, dump_unused, which dumps the contents of
1655all unused blocks to stdout. (Useful as an emergency try-to-find
1656deleted data command.)
1657
1658Added a new debugfs command, imap, which prints the location of a
1659specified inode in the inode table.
1660
1661Fixed a bug in the badblocks program which caused it to use one bit of
1662randomness in its non-destructive read/write test, instead of using a
1663full 8 bits of randomness.
1664
1665Added a new option (-t) to badblocks, which allows the user to control
1666the test pattern(s) used when checking a disk.
1667
1668The blkid probe function now more correctly detects UDF filesystems.
1669
1670Fixed a bug in the blkid library which caused it to not update its
1671cache if a filesystem changes from having a label to not having a
1672label.
1673
1674Fixed a bug in the blkid library wihch could avoid an infinite loop
1675in blkid_find_dev_with_tag() if /proc is not mounted and there the
1676/etc/blkid.tab file has not yet been created.
1677
1678Fixed the badblocks program so that the destructive read/write test
1679honors the -c option, and to use O_DIRECT when possible to avoid
1680thrashing the system block buffer cache.
1681
1682Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -04001683 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001684 - Removed testing NYC translation
1685 - Fixed NLS support for message abbrevations in e2fsck
1686 - Remove de-utf.po, since we shouldn't have two versions using different
1687 charset encodings.
1688 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
1689 simplify the statistics reporting in e2fsck.
1690
1691Changed configure.in so that its defaults for *BSD systems no longer
1692build an fsck wrapper, and not to install in /usr/local by default.
1693
1694Fixed some minor spelling errors/typo's in e2fsck and the configure
1695script.
1696
1697Fixed various Debian packaging issues (see debian/changelog).
1698
1699Updated and clarified man pages. (Addresses Debian Bug #195616)
1700
1701Programmer's notes:
1702-------------------
1703
1704Fix gcc -Wall nitpicks.
1705
1706Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
1707NLS support by default. (Added partial workaround for gettext/Darwin
1708incompatibility problems.)
1709
1710Added full MIT KRB5 and Himdall compaibility support to the com_err
1711library and the compile_et program. (Addresses Debian bug #191900)
1712
1713Added the blkid_known_fstype() function to the blkid library, which
1714returns true if it is passed a filesystem type which is recognized by
1715the blkid probing functions.
1716
1717Improved the documentation for the blkid library.
1718
1719Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
1720returns the hardware sector size of a device, if it is available.
1721
1722Added a dependency in the blkid library's .so file to the uuid
1723library, since the former uses the latter. (Addresses Debian bug
1724#194094)
1725
1726Added --with-diet-libc and --disable-evms to the configure script.
1727
1728Fixed a minor memory leak in the badblocks program.
1729
1730Fixed a portability problem in tune2fs --- not all systems have strptime().
1731
1732Fixed a portability problem in debugfs with the use of getopt() more
1733than once. Old-style BSD, new-style BSD, and Linux C libraries all do
1734things differently.
1735
1736Add support Windows support to ext2fs_get_device_size().
1737
1738Added (normally disabled) debugging code to the Unix I/O manager which
1739causes it to disable all userspace caching if the NO_IO_CACHE is
1740defined.
1741
1742Changed the test I/O manager so it can always be linked into e2fsck,
1743mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
1744configure script. The test I/O manager will only print any debugging
1745information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
1746variables are set, which specifies which I/O operations are logged and
1747a block number to watch, respectively. The log messages are sent to
1748stderr by default, unless a filename is specified via the
1749TEST_IO_LOGFILE environment variable.
1750
1751
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04001752E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001753===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001754
Theodore Ts'oba142c12003-04-16 00:59:59 -04001755Added a new utility program, logsave, which captures the output of a
1756command in a log file, even if the containing directory hasn't been
1757mounted yet (in which case the it saves the output in memory until it
1758can write out the logfile). This is useful for capturing the
1759output of fsck during the boot sequence.
1760
1761Fixed some portability problems that were causing problems under
1762the Cygwin32 environment.
1763
1764Mke2fs now interprets a negative number to the -b option as a minimum
1765block size.
1766
1767Fixed a bug in mke2fs which was incorrectly checking the argument to
1768the -g option if the default block size was used. (Addresses Debian
1769bug #188319)
1770
1771Fsck now explicitly ignores tmpfs and devpts, and it will complain if
1772it can not find filesystem checkers for jfs, reseirfs, and xfs.
1773
1774E2fsck now updates the global free block and inode counters from the
1775block group specific counters quietly. This is needed for an
1776experimental patch which eliminates locking the entire filesystem when
1777allocating blocks or inodes; if the filesystem is not unmounted
1778cleanly, the global counts may not be accurate.
1779
1780Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
17812.0 is not yet supported; this only pulled in the bug fixes: fixed
1782possible hangs caused by bugs in calling waitpid, and not setting the
1783pipe to non-blocking mode; also fixed a file descriptor leak; made
1784sure all functions call log entry/exit functions.)
1785
1786Badblocks now flushes its output file as bad blocks are discovered.
1787
1788The uuid library is now more paranoid about assuming the correctness
1789of the /dev/random device; it mixes in a stream of bytes from
1790random/srandom, just in case.
1791
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001792Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04001793maintainer of e2fsprogs. Other various Debian-specific packaging
1794cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001795
1796Move the source tarball generation functions from the top-level
1797makefile to the util/gen-tarball script.
1798
1799Updated the Turkish .po translation file.
1800
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001801Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001802it more compatible with com_err libraries from those distributions.
1803
1804Changed dumpe2fs to always display the superblock fields relating to
1805the journalling and/or directory indexing feature even if those
1806features are not enabled.
1807
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001808Updated and clarify copyright statement vis-a-vis alpha releases of
1809e2fsprogs.
1810
1811The ss library will now try to dynamically link to the readline
1812library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04001813the debugfs program now has line editing and history features. The
1814SS_READLINE_PATH environment variable is used to find a readline or
1815readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001816
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001817E2fsck now finds most duplicate filenames (all when rebuilding all
1818directories via the -D option) and offers to delete or rename
1819duplicate filenames/directory entries. (Addresses Debian Bug #176814).
1820
1821Fix bug in e2image. When writing out a raw image file, include data
1822blocks from symlinks that do not store the symlink within the inode.
1823
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001824Fix bug in resize2fs which incorrectly moved the block and inode
1825bitmaps for sparse superblock filesystems and incorrectly marked
1826blocks as in use. (Addresses Debian bug #174766)
1827
1828Added a new shared library, the blkid library, which efficiently
1829allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
1830and UUID filesystem specifiers without needing to search all of the
1831devices in the system. Instead, the device is looked up in a cache
1832file, and then verified to make sure the blkid cache is correct.
1833
1834Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
1835the device name, using the blkid library. (Addresses Debian bugs
1836#166048, #179671)
1837
1838Fsck now supports backslash escapes in /etc/fstab so that \040 can be
1839used for spaces in device labels.
1840
1841Removed 32-bit limitations for debugfs's dump command.
1842
1843If the user specifies a large number of inodes, Mke2fs will
1844automatically adjust the number of blocks per group to find a valid
1845set of filesystem parameters.
1846
1847Add workaround to detect broken MD devices where when some of the
1848underlying devices are marked read-only, writes to the MD device are
1849silently dropped. E2fsck will detect if there is an attempt to run
1850the journal twice, and abort with an error if this is the case.
1851(Addresses IBM Bugzilla bug #1226)
1852
1853E2fsck will print an error if more than one of the -p/-a, -n or -y
1854options are specified.
1855
1856E2fsck will fix HTREE corruptions in preen mode, without stopping the
1857boot process. This is needed because the 2.4 ext2 filesystem
1858accidentally had the INDEX_FL backwards compatibility code removed.
1859
1860Mke2fs no longer creates filesystems with the dir_index flag set by
1861default; the user has to specifically request it.
1862
1863Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04001864#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001865
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001866Created man page for the mk_cmds program (from the libss library).
1867
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001868Programmer's notes:
1869-------------------
1870
1871Fix various gcc -Wall nits.
1872
1873Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001874successfully under Solaris and Apple/Darwin.
1875
1876Fixed a Makefile dependency to allow building e2fsprogs using parallel
1877make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001878
1879Changes to create a subset distribution which consists only of the
1880et, ss, uuid, and blkid libraries. The configure script and top-level
1881makefile were changed to support working with a subset distribution.
1882
Theodore Ts'oba142c12003-04-16 00:59:59 -04001883Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
1884actually used, and might people who are looking for
1885EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
1886
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001887Updated debian files to fix a number of Lintian warnings.
1888
1889Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001890
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04001891Removed unnecessary libraries from being linked into the fsck, lsattr,
1892chattr, and blkid executables.
1893
Theodore Ts'o38513012002-11-09 15:00:56 -05001894E2fsprogs 1.32 (Nomvember 9, 2002)
1895==================================
1896
1897Fixed a bug in the Unix I/O routines which caused needless writebacks
1898of clean blocks from the unix_io cache (they were erroneously marked
1899as being dirty, so they were getting written back to disk before
1900getting evicted from the disk cache). This was harmless, but it
1901significantly slowed down e2fsck.
1902
1903Made some other minor optimizations to the Unix I/O routines to save a
1904small amount of CPU time.
1905
1906Updated internationalization files.
1907
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001908
Theodore Ts'oae65b292002-11-08 20:08:48 -05001909E2fsprogs 1.31 (Nomvember 8, 2002)
1910==================================
1911
1912Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
1913compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
1914handling for child process that die unexpectly. Add a hack to force
1915mkfs to create filesystems that won't cause problems with hardware
1916that has 2k or 4k minimum blocksize requirements. Read from child
1917processes in non-blocking mode, so that the GUI continues to update.
1918
1919Fix e2fsck so that it returns the appropriate exit code when the root
1920filesystem has been changed, so that system's rc scripts will be told that
1921the system needs to be rebooted.
1922
1923Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
1924was set, some of the descriptor blocks that should have been written
1925out were getting skipped.
1926
1927Changed e2fsck to force out changes to the backup copies of the
1928superblock and block group descriptors when important changes are made
1929to those data structures.
1930
1931Fix a bug where e2fsck could erroneously mark a filesystem as being
1932clean if a check of dirty filesystem is interrupted with a ^C. (Bug
1933introduced in e2fsprogs 1.28.)
1934
1935If journal debuging is enabled using --enable-jbd-debug, the debugging
1936level is now set via the E2FSCK_JBD_DEBUG environment variable.
1937
1938If byteswapping support is disabled using configure --disable-swapfs,
1939skip the tests which depend on byte-swapping, so that "make check"
1940won't bomb out.
1941
1942Lshattr will now display the indexed directory flag. Also, some of
1943the more esoteric compression flags are supressed unless compression
1944support has been enabled.
1945
1946Update man pages.
1947
1948
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001949E2fsprogs 1.30 (October 31, 2002)
1950=================================
1951
1952When resizing a filesystem, and inodes need to moved, resize2fs will
1953update the inode's ctime field, and the mtime field of the containing
1954directories, so that incremental backups using dump/restore will work
1955correctly.
1956
1957In order to avoid spurious errors, e2fsck wil check the last
1958superblock write time to determine whether or not it can safely use
1959the LOW_DTIME checks to determine if there are inodes on the orphan
1960inode linked list that had somehow gotten disconnected. (Addresses
1961Sourceforge bug #620980)
1962
1963Partition in /proc/partitions that being with the string "lvm" are
1964considered real partitions even if they do not end with a number.
1965
1966Fixed a bug in the the uuid generation function, where if /dev/urandom
1967is not present, but /dev/random is, and there isn't sufficient
1968entropy, the get_random_byte function could spin a loop forever.
1969
1970E2fsck, mke2fs, etc. will now reliably notice when image files are
1971mounted using the loopback interface. (Addresses Sourceforge bug
1972#619119)
1973
1974When flushing buffers (as is done by badblocks, for example) check to
1975see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
1976FDFLUSH ioctl which causes the MD device driver which causes confusing
1977syslog messages about obselete ioctl messages. (Addresses Sourceforge
1978bug #545832).
1979
1980Debugfs's write command now checks to see if the destination filename
1981exists before creating it. (Addresses Sourceforge bug #478195.)
1982
1983When installing man pages, search for compressed man pages using all
1984commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
1985
1986Fixed a bug in fsck where multiple filesystems specified on the
1987command were not being checked in parallel due to a logic bug
1988introduced to support the FSCK_MAX_INST environment variable.
1989
1990We have added a new superblock field, s_mkfs_time, which indicates
1991when a filesystem was created. It is set via mke2fs, and printed out
1992by dumpe2fs, but is not actually touched by the kernel.
1993
1994Dumpe2fs has been made more robust by not aborting if there is an
1995error reading the block/inode bitmaps; instead it will still print out
1996the location of the block/inode bitmaps and inode table.
1997
1998Add support for the an alternative block group descriptor layout which
1999allows for on-line resizing without needing to prepare the filesystem
2000in advance. (This is the incomat feature flag meta_bg.)
2001
2002Add support for storing default mount options in the superblock, so
2003that the filesystem can be mounted with specific mount options without
2004needing to specify them on the mount command line or in the /etc/fstab
2005file.
2006
2007Add support for a new inode flag, which is to be used for indicating
2008the top of directory hierarchies for the Orlov block allocator.
2009
2010Fix e2fsck so that if it creates the lost+found directory, it does so
2011with the more apporpriate permissions of 0700. Also change
2012mklost+found so that it also creates the directory 0700.
2013
2014Fixed format bug in e2fsck if NLS is in use.
2015
2016Add a German translation for e2fsprogs's NLS support.
2017
2018Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
2019the beginning of the inode table. This won't matter much, since if
2020there is a bad block at the beginning of the inode table, the root
2021directory won't be available. But at least e2fsck won't crash in this
2022case.
2023
2024Fixed endian problems in the htree code for e2fsck and debugfs.
2025
2026When byte-swapping a filesystem on a PPC architecture, byte-swap the
2027bitmaps since the historical big-endian ext2 variant had byte-swapped
2028bitmaps, and the ext2fs library assumes this. This fixes the
2029regression test suite on PPC machines.
2030
2031Fix e2image so that it handles a bad block in the inode table
2032appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04002033
2034E2fsck now uses a more sophisticated algorithm to salvage corrupted
2035directories that recovers more information in the corrupted directory
2036block.
2037
2038E2fsck now performs additional consistency checks on indexed (HTREE)
2039directories.
2040
2041Fix bug where efsck might get confused about whether a completely
2042empty directory block is an empty leaf block or an interior htree
2043node. This could cause e2fsck to get confused into think that a valid
2044indexed directory was corrupted.
2045
2046E2fsck no longer creates an empty directory entry at the end of a
2047directory block when optimizing a directory. This would cause some
2048earlier versions of the dxdir kernel code to corrupt the directory
2049when attempting to split a node containing an empty directory entry.
2050
2051E2fsck could sometimes in rare circumstances leave the indexed flag
2052set after a small directory was optimized by compressing it instead of
2053indexing it. (This should never happen in real life, since
2054directories that small wouldn't have been indexed, but better safe
2055than sorry.)
2056
2057E2fsck now only updates the master superblock in all cases. This
2058slightly shortens its run time.
2059
2060Ext2ed can deal with directory entries of length 0; previously it
2061would get stuck in an infinite loop.
2062
2063Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
2064specifiers. (Sourceforge patch #613447)
2065
2066Badblocks will now work correctly on read-only devices such as
2067CD-ROM's. (Sourceforge patch #600451)
2068
Theodore Ts'o5d823a42002-11-01 02:13:53 -05002069Updated and clarified man pages. (Addresses Debian bug #167108)

Theodore Ts'oc6633052002-09-24 01:26:50 -04002072E2fsprogs 1.29 (September 24, 2002)
2073===================================
2074
2075Fixed a bug in e2fsck which could corrupt a directory when optimizing
2076it (via the -D option) or rebuiliding the hash tree index with a 1 in
2077512 probability, due to a fence post error.
2078
2079Fixed a bug in the LVM support code which caused LABEL='xxx' not to
2080work correctly.
2081
2082Mke2fs now enables the directory indexing flag by default. (Since
2083this is a compatible feature flag, it's safe to do so.)
2084
2085Tune2fs will support setting the directory indexing feature flag. It
2086will automatically set up the default hash algorithm and hash seed
2087fields in the superblock.
2088
2089If the bone-headed user enters the root filesystem twice in
2090/etc/fstab, the -R option which skips the root filesystem will skip
2091all of them. (Addresses Debian bug #159423). Note! This is not a
2092precedent for dealing intelligently with any other kind of doubled
2093entry in /etc/fstab!
2094
2095
2096Programmer's notes:
2097-------------------
2098
2099Removed perror declaration in lib/et/internal.h. All modern systems
2100can be expected to define perror() these days. Besides, the lib/et
2101code wasn't using perror at all anyway. :-)

Theodore Ts'ob7bad612002-08-31 03:00:33 -04002104E2fsprogs 1.28 (August 31, 2002)
2105================================
2106
2107Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2108for setting the htree flag is not included yet, although it can be
2109manually turned on via the debugfs program.
2110
2111Clarified e2fsck error message which is printed when it cannot find
2112sufficient contiguous block when relcating filesystem metadata.
2113
2114Added support for building an EVMS plugin module for ext2/3. This
2115module is substantially the same as the EVMS module shipping with EVMS
21161.1, with one or two bugfixes. E2fsprogs can also build this plugin
2117for use with EVMS 1.0 (which did not include the ext2 plugin module),
2118if the configure --enable-old-evms flag is given.
2119
2120Fsck will search through EVMS volumes when trying to resolve
2121filesystem specifications such as LABEL=xxx or UUID=xxx.
2122
2123Added a new utility program, /sbin/findfs, which will return
2124filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2125the device name.
2126
2127Update and clarified various man pages. (addresses Debian Bug #145044,
2128#146437, #131350, #151990, #144621, #141938)
2129
2130If there are no filesystems specified on fsck's command line, fsck now
2131treat that as if the -As options were given. Previously it would
2132simply do nothing. (Addresses Debian Bug #153102)
2133
2134Mke2fs no longer treats a failure to be able to clear the MD signature
2135at the end of the filesystem as a fatal error. (Addresses Debian Bug
2136#155007)
2137
2138The e2p library functions (which are used by lsattr and chattr) now
2139double check to make sure the file is a regular file or directory
2140before attempting to use the ext2 ioctls. Some device drivers
2141unfortunately respond to the ext2 ioctl's with unknown behaviour.
2142(Addresses Debian Bug #152029).
2143
2144The extended attribute handling has been updated to correspond with
2145the latest V2 bestbits ACL code.
2146
2147Fixed bug in e2fsck which caused it to not clear the dtime field when
2148processing truncated inodes on the orphan list. This could cause data
2149loss(!) if a filesystem is rebooted before a truncate has been
2150committed.
2151
2152E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2153algorithms. This makes e2fsck much faster in the case of severely
2154corrupted filesystems where a large number of blocks are claimed by a
2155large number of inodes. (Thanks to the 2.5 IDE device driver for
2156inspiring this work.)
2157
2158Resize2fs has been significantly sped up when shrinking and expanding
2159a filesystem by a very small number of blocks (for example, when EVMS
2160is converting a partition to be an EVMS legacy volume).
2161
2162Added a new option to e2fsck, -D, which will optimize or compress all
2163of the directories in the filesystem.
2164
2165E2fsck now catches SIGINT and SIGTERM to make sure it will can
2166properly clean up and only exit at safe points. Fsck will pass
2167SIGINT/SIGTERM to its child processes, and wait until they have all
2168exited before it exits.
2169
2170The uuid parsing code in the uuid library now properly complains when
2171an illegally formated uuid is presented to it. (Addresses Debian bug
2172#152891)
2173
2174Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2175and 2.4.17, since the workaround can cause problems when using a 2.4
2176kernel with an old version of glibc built with the 2.2 headers.
2177
2178Fixed a bug in mke2fs where it wasn't properly clearing the initial
2179superblock used by other filesystems. (Addresses Debian bug #147256.)
2180
2181Added support for the synchronous directory feature written by Andrew
2182Morton.
2183
2184The debugfs program can delete directories using the rmdir command.
2185
2186Add support for 8k and 16k filesystems (for systems with page sizes
2187that are greater or equal to 8k or 16k, respectively). Note that
2188these filesystems can not be mounted on x86 systems, or other systems
2189with only 4k page sizes, due to limitations in the current Linux VM
2190code.
2191
2192Resize2fs requires that the filesystem state be valid and have no
2193errors; otherwise, e2fsck -f must be run first. (Previously it simply
2194required that the last fsck time be greater than the last mount time.)
2195
2196Configure now defaults the man pages directory to /usr/share/man on
2197Linux systems.
2198
2199E2fsck now offers to truncate inodes which contain too many blocks (so
2200that i_blocks would overflow. Also fixed handling of large sparse
2201files.
2202
2203E2fsck now more completely checks for symlink validity, including
2204requiring NULL termination and length checks.
2205
2206E2fsck will offer to try forcing a disk write to remap a bad block
2207after finding a read error when reading a filesystem metadata block.
2208
2209Fixed a bug in debugfs which caused the -b and -s options to crash
2210debugfs, as well as breaking the testb, setb, and clearb functions.
2211
2212Added a bmap command to debugfs which calculates the logical to
2213physical block mapping for a particular inode.
2214
2215Fixed a bug in code which checked to see if a device was mounted which
2216sometimes (rarely) failed in the case of a plain file.
2217
2218Fixed a bug in resize2fs where when it reported an error, it would
2219print a message erroneously indicating that the filesystem had been
2220resized before it aborted.
2221
2222When resizing a plain file which is smaller than the requested size,
2223resize2fs will attempt to extended the file so that programs like
2224e2fsck will not complain that the file is too small.
2225
2226Resize2fs will print the actual new size of the filesystem when it is
2227finished resizing.
2228
2229Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2230information on big-endian systems.
2231
2232
2233Programmer's notes:
2234-------------------
2235
2236Fixed collisions with C++ reserved words.
2237
2238Added portability fixes for building e2fsprogs on the HURD and AIX.
2239
2240Added the ext2ed program for creation of test cases. (ext2ed has many
2241limitations and bugs which make it unsuitable for production use.)
2242
2243The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2244flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2245name_len field is byte swampped on big-endian machines, since in the
2246V2 structure, name_len is a char field which is doesn't need to be
2247byte swapped --- except if an old-style kernel had byte-swapped the
2248name_len field as part of the V1 structure.
2249

Theodore Ts'oa8e77242002-03-08 03:12:14 -05002251E2fsprogs 1.27 (March 8, 2002)
2252==============================
2253
2254The warning messages for mke2fs now go to standard error.
2255
2256Fixed to make sure "make check" runs all of the test programs with
2257LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2258
2259The mke2fs program checks the boot sector for the BSD disk label, and
2260avoids erasing it if it is there.
2261
2262Fixed a bug in e2fsck which caused it to core dump if the journal
2263inode was missing when it was supposed to be there.
2264
2265E2fsck now prints ranges in pass 5 when printing deltas for the block
2266and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002267
2268Debugfs's "ls -l" command now will print out the file type information
2269in the directory entry.
2270
2271Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2272mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2273
2274Debugfs can now examine the experimental directory indexing
2275information.
2276
Theodore Ts'oa471ac52002-03-05 03:37:06 -05002277Fixed bug in debugfs which caused it to core dump if modify_inode is
2278called without an open filesystem.
2279
2280The debugfs lsdel command now runs its output through a pager first.
2281
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002282When installing manual pages, remove the compressed manual pages first.
2283
2284Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2285
2286Fix the 2.4 resource limitation workaround introduced in 1.26 which
2287actually broke things on mips32, sparc32, and Alpha platforms.
2288
Theodore Ts'oa471ac52002-03-05 03:37:06 -05002289Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2290(which is required by the newer libintl libraries).
2291
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002292Programmer's notes:
2293-------------------
2294
Theodore Ts'oa8e77242002-03-08 03:12:14 -05002295Fixed various gcc -Wall complaints.
2296
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002297Fixed a few memory leaks in the e2fsck journaling code, and in the
2298ismounted code checking for a swap device.
2299
2300Add new inode I/O abstraction interface which exports an inode as
2301an I/O object.
2302
2303Exported ext2_file_flush as a public interface.
2304
2305In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
2306
2307Lots of small random portability fixes to make e2fsprogs build under
2308AIX --- even without the 5L compatibility toolkit, and even using the
2309uber-crippled AIX native C compiler.
2310
2311
Theodore Ts'o06987392002-02-03 01:36:54 -05002312E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002313=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002314
Theodore Ts'o446314f2001-12-24 15:22:27 -05002315Dumpe2fs will keep going now if the bad block inode can't be read.
2316(Previously it stopped with a fatal error.)
2317
2318E2fsck will now give an opportunity to run the journal even if the
2319recovery flag is not set. This is the default behaviour if e2fsck is
2320using a backup superblock, since the needs_recovery flag will never be
2321set in the backup superblock copies.
2322
2323E2fsck now automatically finds the backup superblock/group descriptors
2324even when the primary superblock is completely destroyed for 2k and 4k
2325filesystems. (Previously it just guessed/assumed that we were dealing
2326with a 1k filesystem in that case, and users had to manually specify
2327the backup superblock number.)
2328
2329Fixed a bug in e2fsck where it dereferences a null pointer when there
2330is a problem opening a filesystem in preen mode.
2331
2332E2fsck now handles external journals correctly; previously it trashed
2333the external journal device if the journal needed to be replayed.
2334
2335Work around ulimit incompatibility problem caused by recent 2.4
2336kernels; the unix IO module will automatically try to set any resource
2337limits to be infinite on startup.
2338
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002339Fixed a bug in e2fsck where it wasn't allocating a new block or inode
2340bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04002341 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002342
2343E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
2344clearing the new V2 fields if they do not make sense or if the ext3
2345superblock is version 1 superblock.
2346
2347E2fsck will automatically relocate the ext3 journal from a visible
2348file (i.e., /.journal) to an hidden inode if the filesystem has been
2349opened read/write. This allows the users to add a journal while the
2350filesystem is mounted, but the next time the system is rebooted, the
2351journal file will disappear. This avoids problems with backups,
2352stupid operators with superuser bits, etc.
2353
2354Fix a bug in fsck where it would not support a filesystem type of
2355"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
2356
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002357Fsck now supports fstab entries of the form "ext3,ext2". It will also
2358automatically identify reiserfs filesystems.
2359
2360The number of processes spawned by fsck can now be limited using the
2361FSCK_MAX_INST environment variable.
2362
Theodore Ts'o446314f2001-12-24 15:22:27 -05002363Fsck now searchs the LVM proc hierarchy to find logical volumes which
2364should be searched for UUID and label information.
2365
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002366Work around a bug in 2.4.10+ kernels by trying to unset the filesize
2367limit if at all possible, when opening a block device. (The filesize
2368limit shouldn't be applied against writes to a block device.)
2369
Theodore Ts'o446314f2001-12-24 15:22:27 -05002370In mke2fs and e2fsck, specifying the -c option twice will now do
2371a read/write test on the disk. Update the man pages to encourage
2372using the -c option, and to discouraging running badblocks separately,
2373since users tend to forget to set the blocksize when running
2374badblocks.
2375
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002376Mke2fs now automatically clears the immutable attribute on a
2377pre-existing .journal file left over from a previous failed attempt to
2378add a journal to an alreadyy-mounted filesystem.
2379
2380Fixed mke2fs's exit codes to consistently indicate when the mke2fs
2381operation failed.
2382
Theodore Ts'o446314f2001-12-24 15:22:27 -05002383Mke2fs now creates the lost+found directory with permissions of 0700,
2384so that files that had previously lived in protected directory are
2385safe if they get dropped in lost+found and the system administrator
2386doesn't deal with immediately. (Addresses Debian #bug 118443)
2387
2388Mke2fs and e2fsck (and all programs that use the
2389ext2fs_check_if_mounted function) will now properly identify that a
2390device is mounted, even in cases where devfs has confused things with
2391multiple devices names with the same identity, or if a dim-witted
2392system administrator has done something stupid like creating device
2393file aliases in their home directory. Also now checks for swap devices
2394by using /proc/swaps. (Addresses Debian bug #106622)
2395
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002396Added a new option (-T) to tune2fs which sets the time a filesystem
2397was last checked.
2398
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002399Speed up e2image when creating sparse raw image files by optimizing
2400away excess lseek() system calls.
2401
2402Fix support of large (> 2GB) files when used as a filesystem in
2403mke2fs, tune2fs, debugfs, and findsuper.
2404
2405Debugfs's stat and icheck commands now properly deals with large (>
24062GB) files.
2407
2408Debugfs's set_super_value command now prints out the list of valid
2409superblock fields which can be set using the command.
2410
Theodore Ts'o446314f2001-12-24 15:22:27 -05002411Debugfs's rm and kill_file command now updates the superblock free block
2412and inode counts, thus keeping the filesystem consistent.
2413
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002414Debugfs's lsdel command now takes an optional argument which allows
2415the user to only see the most recently deleted files.
2416
2417A new command (undel) was added to debugfs which automates
2418undeleting a deleted inode and linking it back to a directory.
2419
2420Debugfs's ls command now takes a new option, -d, which lists
2421deleted directory entries.
2422
2423Debugfs's testb, freeb, setb, and find_free_block commands now take an
2424optional count argument.
2425
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002426Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
2427be used to signal that a particular inode should not be eligible for
2428tail-merging --- this is needed for programs like LILO.
2429
2430The findsuper (an unreleased, uninstalled utility program) has been
2431improved to add extra validity checks and to add a progress meter.
2432(It is still an unsupported program; the officially supported way to
2433recover from a trashed partition table is to use gpart; findsuper is
2434for wizards only. :-)
2435
2436Debugfs was fixed to compile with "configure --disable-swapfs".
2437
Theodore Ts'o446314f2001-12-24 15:22:27 -05002438Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002439
2440Added new translation file for Turkish.
2441
Theodore Ts'o446314f2001-12-24 15:22:27 -05002442Programmer's notes:
2443-------------------
2444
2445Fix general gcc -Wall complaints.
2446
2447E2fsprogs (mostly) works with the dietlibc.
2448
2449The programming texinfo file has been expanded to include description
2450of additional libext2fs functions. (Still not compeltely done, but a
2451lot of the more important functions have been documented.)
2452
2453Added a umask structure to struct_ext2_filsys, which currently only
2454modifies the behaviour of ext2fs_mkdir(), but if we add any file
2455creation functions to libext2fs, we should also make sure they respect
2456the umask setting.
2457
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002458The build-rpm script was fixed to be a bit more safe.
2459
2460The tests' Makefile now has a way of automating test case creation
2461for e2fsck, using "make testnew".
2462
2463Created a new function, ext2fs_dir_iterate2 which passes more
2464information to the callback function (identical to the one used by
2465ext2fs_dblist_dir_iterate). The directory iterator functions take a
2466new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
2467directory entries. If the directory entry is deleted, the callback
2468function will be called with the entry paraemter set to
2469DIRENT_DELETED_FILE.
2470
2471Added new functions, ext2fs_inode_alloc_stats and
2472ext2fs_block_alloc_stats, which takes updates block/inode allocation
2473statistics in the bitmaps, block group descriptors, and superblock
2474when inodes or blocks are allocated or deallocated.

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04002477E2fsprogs 1.25 (September 20, 2001)
2478===================================
2479
2480This is primarily a bug-fix release; no new features were added, but
2481there are a number of embarassing bug fixes and cleanups applied.
2482
2483Fix a bug mke2fs which causes stack garbage to be written to disk when
2484zapping disk sectors. (This bug could cause mke2fs to core dump for
2485some kernels, I suspect with security enhancement patches.)
2486
2487Remove unneeded #include of <linux/config.h> which was breaking
2488building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
2489
2490Updated tune2fs man page to reflect the fact that adding or removing a
2491journal doesn't require running e2fsck.
2492
2493Remove use of AC_REQUIRE from autoconf which had been used to prevent
2494AC_CANONICAL_HOST from being called twice; unfortunately this causes
2495recent autoconf to bomb out since they don't allow AC_REQUIRE to be
2496used outside of autoconf macros. Fortunately, it doesn't seem to be
2497necessary any more, anyway.
2498
2499E2fsck will now not fall back to an alternate superblock if the user
2500specifies the superblock location explicitly on the command-line.
2501This allows easier recovery from a situation where the primary
2502superblock and block groups are slightly corrupted, but the backup
2503superblocks are completely broken.
2504
2505Fix problem which caused compile_et and mk_cmds to blow up if
2506e2fsprogs was in a directory with a pathname that contained spaces.
2507
2508We are now more paranoid about checking the entry in /etc/mtab to make
2509sure the filesystem is really mounted, since some broken distributions
2510(read: Slackware) don't initialize /etc/mtab before checking non-root
2511filesystems. (Slackware also doesn't check the root filesystem
2512separately, and reboot if the root filesystem had changes applied to
2513it, which is dangerous and broken, but there's nothing I can do about
2514that.)
2515
2516Make UUID library C++ friendly by adding appropriate extern "C"
2517declarations and using const in the function declarations.
2518
2519Fix up the com_err texinfo file so that it can product a valid info
2520file (previously, it could only be used to generate paper
2521documentation using texinfo.tex).
2522
2523
Theodore Ts'ofb707752001-09-04 15:00:37 -04002524E2fsprogs 1.24a (September 2, 2001)
2525===================================
2526
2527Fix brown-paper bug in mke2fs which caused it to segfault when
2528printing the version string.
2529
2530
Theodore Ts'o109624a2001-08-31 00:59:55 -04002531E2fsprogs 1.24 (August 30, 2001)
2532================================
2533
2534Revert the BLKGETSIZE64 support, since for some distributions, this
2535ioctl has been used by an unofficial kernel patch to update the last
2536sector on the disk, and this was causing disk corruption problems as a
2537result.
2538
2539Mke2fs is now more careful about zapping swap space signatures and
2540other filesystem/raid superblock magic values so that programs like
2541mount who try to use hueristics to determine the filesystem type of a
2542partition are less likely to be confused.
2543
2544E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
2545regular file (since Andreas Dilger's on-line resizing tools will set
2546its mode bits).
2547
2548Fixed some minor texinfo, man pages nits for spelling errors,
2549texinfo warnings, etc. (Addresses Debian bug #110621.)
2550
2551E2fsprogs program no longer print the filesystem version number
2552(i.e. 0.5b), since it only confuses people and doesn't serve any real
2553purpose.
2554
2555E2fsck will once again compile under libc5, since it will supply its
2556own version of strnlen if necesssary.
2557
2558mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
2559when specifying the external journal device. tune2fs will also search
2560devices looking for the externla journal debice when removing.
2561
2562E2fsprogs 1.23 (August 15, 2001)
2563================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002564
2565Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04002566correctly handle a filesystem with EA's and check the EA blocks for
2567corruptions.
2568
Theodore Ts'od494bba2001-08-09 06:14:42 -04002569E2fsck's symlink sanity checking has been cleaned up. It now checks
2570the i_size value of fast symlinks, and checks for immutable flags
2571being set of symlinks, etc.
2572
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002573E2fsck now offers to clear inodes which are special files that have a
2574non-zero i_blocks or i_size field. (The i_size field check was in the
2575previous version of the code, but due to a bug it didn't offer to
2576clear the inode unless i_size and i_size_high were both non-zero.)
2577
Theodore Ts'od494bba2001-08-09 06:14:42 -04002578E2image can now create "raw" image files, which only contain the
2579filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
2580debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04002581
2582Add support for the 64-bit block device patches.
2583
2584Fixed bugs in creating external journals with a 1k blocksize.
2585
Theodore Ts'od494bba2001-08-09 06:14:42 -04002586Add initial support for external journals (so long as the external
2587journal only supports a single filesystem) in e2fsck.
2588
2589Remove requirement for needing to run fsck on a filesystem after
2590removing a journal (either internal or external).
2591
Theodore Ts'obf16d102001-07-27 22:20:06 -04002592The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002593
2594Speed up the check of an ext3 filesystems by avoiding a needless flush
2595of all of the superblock and block group descriptors.
2596
Theodore Ts'od494bba2001-08-09 06:14:42 -04002597Speed up creating an internal journal using tune2fs in the case where
2598the filesystem has a lot blocks already allocated.
2599
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002600Tune2fs has been fixed to make sure that only error messages go to
2601stderr, and normal message go to stdout. (Addresses Debian bug #108555)
2602
Theodore Ts'od494bba2001-08-09 06:14:42 -04002603Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002604now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04002605
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002606Add support in fsck for the filesystem type "auto".
2607
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002608Fsck -A will not try to interpret device names for filesystems which
2609have a pass number is 0. (Addresses Debian bug #106696).
2610
2611Fsck prints a warning message if now valid filesystems are passed to
2612it. (Addresses Debian Bug #107458.)
2613
Theodore Ts'o9249d982001-07-20 18:14:10 -04002614E2fsck now gives an explicit warning if there filesystem still has
2615errors at the end of the run. (Addresses Debian bug #104502)
2616
Theodore Ts'od494bba2001-08-09 06:14:42 -04002617E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002618reflects an error. E2fsck will also not run the orphan list if the
2619filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04002620
2621E2fsck now prints the number of large files when given the -v option.
2622
2623Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04002624
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002625Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04002626
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002627
Theodore Ts'o19d6b542001-06-23 00:13:09 -04002628E2fsprogs 1.22 (June 22, 2001)
2629==============================
2630
2631Fixed a bug in e2fsck's handling of orphan inodes which are special
2632files (i.e., block/character device files, named FIFO's, etc.).
2633
2634Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
2635tune2fs to fail at adding a journal to a mounted filesystem.
2636
2637Fixed a few big-endian bugs in e2fsprogs
2638 * The directory block functions were accidentally reporting
2639 some directories as corrupted when they weren't.
2640 * If e2fsprogs is compiled --disable-swapfs, the C language
2641 equivalents weren't being included for big-endian platforms.
2642 (Fixes Debian bug #101686).
2643
2644Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
2645
2646Programmer's notes:
2647-------------------
2648
2649Use platform independent method of defining the BLKFLSBUF and FDFLUSH
2650ioctls, and allow them to be defined for non-i386 platforms.
2651
2652The uuid.h header file is now protected against multiple inclusions.
2653
2654E2fsprogs is now being developed using BitKeeper. Changed the test
2655scripts to deal with BK's stripping CR characgters from text files,
2656and changed the top-level Makefile.in to avoid including BitKeeper
2657files when generating the source tarball.
2658
2659
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002660E2fsprogs 1.21 (June 15, 2001)
2661==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00002662
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002663Added new configure flags which allow a subset e2fsprogs to be built;
2664this is most useful for boot floopies, since the resulting shared
2665libraries and programs are slimmed down by removing features that
2666aren't necessary for a boot floppy. The new flags that were added
2667are: --disable-swapfs, which removes support for byte swapping old
2668legacy PPC/68k filesystems, --disable-debugfs, which removes support
2669for debugfs from the libext2fs library, --disable-imager, which
2670removes support for the e2image program, and --disable-resizer, which
2671removes support for resize2fs.
2672
2673E2fsck now prints the number of mounts or days elapsed since the last
2674check when e2fsck is forced to check an otherwise clean filesystem.
2675
2676Tune2fs now prints an informative message about how often a filesystem
2677will be checked when adding a journal to the filesystem, to remind the
2678user that he/she may want to adjust those parameters using tune2fs
2679-c/-i.
2680
2681Worked around hurd brain-damage which causes e2fsck to sometimes
2682believe a filesystem is the root filesystem based on device numbers
2683(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
2684violation).
2685
2686Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
2687erroneous error with the -F option was specified.
2688
2689Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002690ext3 0.7a.
2691
Theodore Ts'o767de092001-06-02 01:20:18 +00002692Fixed two bugs in e2fsck's handling of dup block handling, dealing
2693with relatively uncommon edge cases: a directory with an indirect
2694block which is claimed by another file, and when the last inode in the
2695filesystem has blocks claimed by another file.
2696
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00002697E2fsck now checks to see if the i_size field of a fast symlink is too
2698big, and offers to clear the symlink if so.
2699
2700E2fsck now checks to see if i_size_high of special files is non-zero,
2701and offers to clear i_size_high.
2702
Theodore Ts'o767de092001-06-02 01:20:18 +00002703Fix e2fsck's handling of incompatible journal flags so that the user
2704has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00002705entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00002706
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002707Fixed a bug in fsck which could cause it to core dump if a mix of
2708standard and non-standard device names are used in /etc/fstab.
2709(Debian bug #100559)
2710
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002711Fixed a bug in debugfs which caused read errors when copying a file to
2712not be noticed.
2713
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002714The debugfs set_super_value command can now modify the s_lastcheck field.
2715
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002716Fixed a bug in lsattr and chattr which was accidentally introduced in
27171.20 to support > 2GB files; both lsattr and chattr wasn't reading
2718directories correctly because the change modified the layout of struct
2719dirent to be incompatible with the libe2p shared library.
2720
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002721Cleaned up the mke2fs manual page and included a discussion about why
2722it's good to periodically check the filesystem even when journaling is
2723enabled.
2724
Theodore Ts'o767de092001-06-02 01:20:18 +00002725Programmer's notes:
2726-------------------
2727
2728Fix general gcc -Wall complaints.
2729
2730The types needed by the ext2 header files are now provided by
2731lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
2732
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002733Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002734in ext2_types.h. Also, if linux/types.h has already been defined,
2735don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002736
Theodore Ts'o767de092001-06-02 01:20:18 +00002737Fixed make depend script so that it automatically corrects the
2738pathname cleanups performed by make -M, so I don't have to fix them up
2739by hand.
2740
2741Fixed the d_loaddump test case to be more robust, and not depend on
2742bash'isms.
2743
2744Removed debugfs's dependence on pread(), which was accidentally
2745intrudced in e2fsprogs 1.20
2746
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002747Fixed a performance bug in the libext2fs's icount routine; the size
2748estimate of the icount array was incorrectly being calculated.
2749
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002750Removed use of the badblocks compatibility functions in the e2fsprogs
2751programs.
2752
2753Added paranoia code which protects against strange cases where /etc
2754isn't on the root filesystem, or if /etc/mtab doesn't exist.
2755
2756The header file ext2_types.h is now installed.
2757
2758Autoconf is used to determine when we are on big-endian machines,
2759instead of doing run-time tests, to save a few bytes of code.
2760
2761The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
2762functions are no longer inline functions, which saves space and
2763doesn't really cost any real performance.
2764
2765The ext2fs library no longer depends on the e2p library. (What need
2766there was of it --- namely, fsetflags, was coded in-line).
2767
2768Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
2769when the user is stupid and tries compiling the package using "make
2770install" as root.
2771
2772Miscellaneous code cleanups:
2773 * Added missing files from Makefile.in's SRCS file, so that
2774 their dependencies would be properly calculated.
2775 * Removed redundant code
2776 * Fixed comments in code
2777 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002780E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002781=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00002782
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002783Add support for replaying the ext3 journal purely in user mode,
2784including handling the orphaned inode list. Used code contributed by
2785Andreas Dilger, with bug fixes and the orphaned inode handling done
2786by Theodore Ts'o.
2787
2788The mke2fs and tune2fs programs can create or modify a filesystem to
2789include an ext3 journal. Tune2fs also can be used to remove an ext3
2790journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002791
2792E2fsck will now check for the existence of a linked list of orphan
2793inodes in the superblock, and clear those inodes before starting the
2794rest of the filesystem check (but after the journal playback).
2795
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002796E2fsck now validates the file descriptor passed to the -C option,
2797which saves against the completion bar getting written to an
2798unexpected location, such as the disk being checked. (Debian
2799bug/wishlist #55220)
2800
2801E2fsck will now bump the filesystem revision number from zero to one
2802if any of the compatibility bits are set.
2803
2804Fixed a bug where a badly corrupted directory on a big endian system
2805could cause e2fsck to die with a bus error. The
2806ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
2807the ext2 library now does alignment sanity checks on the rec_len field
2808of the directory entry before using it.
2809
2810The ext2 library has been enhanced to make tune2fs safe to run on
2811mounted filesystems. (Users could usually get away with using tune2fs
2812on mounted filesystems before, but with the advent of ext3 and
2813journaling, it became important to make tune2fs was *really* safe for
2814use even when the filesystem being modified is mounted.) E2label is
2815now implemented by tune2fs using an argv[0] dispatch, so that e2label
2816is also now safe for use on mounted filesystems.
2817
2818Added a new program, e2image, which creates a backup of critical ext2
2819filesystem data structures. The generated image file can be examined
2820using dumpe2fs and debugfs. In the future, e2fsck will be able to use
2821the image file to help recover very badly damaged filesystems.
2822
2823Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
2824no longer cause e2fsck to bomb out. Also treat files > 2GB as being
2825large file when deciding whether or not the filesystem has large files.
2826
2827Fixed lsattr and chattr so that they work correctly on large files.
2828(Fixes Debian bug #72690.)
2829
2830Removed limitation in get_device_size() which imposed a one terrabyte
2831filesystem limitation. (Most 2.2 kernels still have a signed int
2832problem which cause 1 TB block device limitation. Fortunately, the
2833kernel patches to fix this are much easier than fixing the 2TB
2834limitation in the kernel. :-)
2835
2836A max_mount_count of zero is now treated as if no mount count were
2837set. (Previously, no mount count was indicated by using -1, and a
2838mount count of zero caused e2fsck to always be run.)
2839
Theodore Ts'o77648562001-05-14 13:04:44 +00002840Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002841
2842Mke2fs now adds some randomness in s_max_mount_count so that multiple
2843filesystems won't be all checked at the same time under normal
2844operations.
2845
Theodore Ts'o5570a652000-08-21 01:23:39 +00002846Fixed bug in the progress bar printing code which could cause e2fsck
2847to core dump on an illegal filesystem.
2848
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002849Fixed bug in fsck which could allow more than one instance of e2fsck
2850to be printing a progress bar. (Debian bug #65267)
2851
Theodore Ts'o5570a652000-08-21 01:23:39 +00002852Fsck using a UUID or a LABEL specifier will work even if devfs is
2853compiled into the kernel and not mounted. If the pathnames in
2854/proc/partitions are incorrect, fsck will search /dev for the correct
2855device (using the new ext2fs_find_block_device library function).
2856Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002857found when they are in use. Support has also been added to support
2858additional IDE disks and the DAC 960 device names. (Debian bug #94159)
2859
2860Fixed a bug in fsck which caused it not deal properly with 16
2861byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002862
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002863Fsck's -t option has been made a lot more flexible. The semantics for
2864what happens if a comma-separated list to fsck has been regularized,
2865and it is now possible to filter what filesystems will get checked
2866based what is in the filesystem's fstab entry's option field. (Debian
2867bug #89483.)
2868
Theodore Ts'o5570a652000-08-21 01:23:39 +00002869The dumpe2fs program can now print out the group description
2870information in hex, and also prints the location of the superblock and
2871block group descriptor for those block groups that have them.
2872
2873Mke2fs now clears the ext2 superblock before it starts creating a
2874filesystem, so that the superblock magic number is only written if the
2875filesystem creation process successfully completes.
2876
2877The debugfs program's stat command now pretty-prints the blocks used
2878by an inode so that it's more compact and informative.
2879
2880The debugfs stats command now uses the same libe2p code (which is used
2881by dumpe2fs) to print the superblock header information. This is more
2882complete, and it avoids a bit of code duplication.
2883
2884Added a new debugfs command, set_super_value (ssv) which allows the
2885user to set arbitrary superblock fields.
2886
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002887Debugfs was extended to support inode numbers in hex (by prefixing
2888them with 0x), and so that modify_inode can set the inode generation
2889number. Also, there is now a new function command called logdump
2890which will dump an ext3 journal.
2891
2892Fixed a bug in debugfs so that quitting out of the pager doesn't kill
2893debugfs.
2894
2895Debugfs's dump command now stops immediately upon reporting a disk
2896read error. (Fixed a bug in ext2fs_file_read library routine which
2897caused debugfs not to stop.) (Debian bug #79163)
2898
2899On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
2900checked before /etc/mtab is used, since /proc/mounts is more likely to
2901be accurate.
2902
2903Added portability fixes for Solaris and Linux/ia64.
2904
2905Various manual pages were clarified and cleaned up. (Fixed debian
2906bugs #63442, #67446, and #87216)
2907
Theodore Ts'o5570a652000-08-21 01:23:39 +00002908
2909Programmer's notes:
2910-------------------
2911
2912The e2fsck message printer now supports %Iu and %Ig, which will print
2913out the inode's user and group owners, respectively.
2914
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002915E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
2916that no longer dependent on the system having the correct version of
2917the kernel header files.
2918
Theodore Ts'o5570a652000-08-21 01:23:39 +00002919Added a new function to libext2, ext2fs_find_block_device(), which
2920searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
2921device given its device number.
2922
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002923Added a new function to libext2, ext2fs_sync_device, which centralizes
2924all of the places which might try to use the BLKFLSBUF or FDFLUSH
2925ioctls (and usually failing to define them since the system header
2926files don't usually do this for us, and we're trying to avoid usage of
2927kernel include files now).
2928
Theodore Ts'o5570a652000-08-21 01:23:39 +00002929Added new utility programs in tests/progs: random_exercise and
2930hold_inode. They aren't built by default; they're useful for
2931exercising ext3 filesystem code.
2932
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002933Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
2934the filesystem close functions to only update the superblock, and to
2935not touch the block group descriptors. Needed by tune2fs when
2936modifying a mounted filesystem.
2937
2938Got rid of struct ext2fs_sb and replaced it with the standard struct
2939ext2_super_block from include/linux/ext2_fs.h. Note: this may break
2940source (but not binary) compatibility of some users of the ext2
2941library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00002942replace of struct ext2fs_sb with struct ext2_super_block, and include
2943the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002944
2945The ino_t type has been renamed ext2_ino_t to protect applications
2946that attempt to compile -D_FILE_OFFSET_BITS=64, since this
2947inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
2948unexpected ABI change.
2949
2950The Makefiles have been reworked so that "make check" can be run from
2951the top-level Makefile.
2952
2953Fix general gcc -Wall complaints and removed dead code.
2954
2955Remove use of NOARGS, because we assume everyone does ANSI C these
2956days.
2957
2958Added build-rpm script from sct.
2959
2960New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
2961to support e2image.
2962
2963New function ext2fs_flush_icache which must be called if the
2964application program modifies the inode table blocks without going
2965through ext2fs_write_inode() interface.
2966
2967New ext2fs_check_mount_point() function, which will return the mount
2968point of a device if mounted.
2969
2970The io_channel abstraction now has an optional interface,
2971io_channel_write_range, which allows specific byte ranges to be
2972written.
2973
2974The unix_io IO channel now supports write-through caching, so that
2975journal creation is more efficient.
2976
2977Added x86 assembly language routines to support byte swapping, to
2978reduce executable size.
2979
2980Fixed bug in the utility program subst so that it's possible to
2981replace a substitution variable with a zero-length string.
2982
2983Fixed numbering e2fsck pass1 problem numbers; an extra zero had
2984slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002985
Theodore Ts'ob777e262000-07-27 01:39:23 +00002986E2fsprogs 1.19 (July 13, 2000)
2987==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00002988
2989Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00002990be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00002991
2992Add experimental support needed for the ext2 compression patches.
2993This requires compiling e2fsprogs with the --enable-compression flag
2994to the configure script.
2995
2996Added ext3 journalling support. E2fsck will run the journal (if
2997necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
2998installed as a symlink to e2fsck. Fsck has been taught about ext3,
2999and treats it the same as ext2 in terms of the progress bar logic.
3000Dumpe2fs will display the superblock journaling information if the
3001filesystem has a journal. The ext2 library will now permit opening an
3002ext3 filesystem with the recovery flag set. This is necessary for
3003on-line dump's to work correctly, but there may be issues with this
3004working well since ext3 is much less agressive about syncing blocks to
3005the filesystem, since they're safe on the journal.
3006
3007Tune2fs and e2fsck have been changed to allow the mount_count check to
3008be disabled by setting max_mount_count to -1. (This was already
3009supported by the kernel.)
3010
3011Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
3012are used for ext3 as well.
3013
3014Added internationalization support for e2fsprogs; must be enabled
3015by passing --enable-nls to configure.
3016
3017Always use the provided ext2fs header files to insulate ourselves from
3018kernel version changes. Which include files are used by e2fsprogs
3019have also been cleaned up to improve portability.
3020
3021Limit the number of times that e2fsck updates the progress bar so that
3022people who are booting using a 9600 baud console don't get swampped by
3023too many updates.
3024
3025Improved the loop detection algorithm in e2sck's pass #3 so that it is
3026much, much faster for large filesystems with a large number of
3027directories.
3028
3029The memory footprint for e2fsck is now slightly smaller than before.
3030
3031E2fsck now checks if special devices have a non-zero size, and offers
3032to clear the size field if it finds such an inode.
3033
3034E2fsck now checks if special devices have the append-only flag set,
3035and offers to clear the inode.
3036
3037E2fsck now properly handles some "should never fail" cases during a
3038bitmap copy in pass5.
3039
3040E2fsck now properly prints control characters in filenames as ^A .. ^Z.
3041
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003042E2fsck now calculates the correct location of the backup superblock in
3043the case of filesystem blocksizes > 1k.
3044
3045Fixed a bug in e2fsck's calculation of the number of inodes_per_block
3046which normally didn't cause problems under most filesystem parameters,
3047but could cause a valid superblock to be rejected in extreme cases.
3048Other checks for validating superblock values were made more
3049stringent.
3050
Theodore Ts'oab146762000-07-07 04:37:35 +00003051Added non-destructive write testing to the badblocks program, courtesy
3052of David Beattie. The badblocks also now has an option to input the
3053current set of bad blocks, so that known bad blocks are skipped to
3054speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00003055feature which causes badblocks to run until it has completed some
3056number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00003057
3058Badblocks now checks to see if the device is mounted and refuses to do
3059the tests involving writing to the device if it is mounted. Also,
3060badblocks now allows the number of blocks to be checked to be
3061defaulted to the size of the partition.
3062
3063Fixed a bug in fsck which didn't allow non-root users to be able to
3064check filesystems if there were any LABEL= or UUID= entries in
3065/etc/fstab.
3066
3067The Hurd doesn't support the filetype filesystem feature. The mke2fs
3068program now makes sure that for the Hurd, the filestype feature is
3069turned off. E2fsck will check to see if the filetype feature is
3070turned on for Hurd filesystems, and offer to turn off the feature.
3071
3072Mke2fs now has a safety check to make sure the number of blocks do not
3073exceed 32 bits even on a 64 bit platform.
3074
3075Really fixed a bug in fsck to allow "fsck -As" to run interactive
3076fsck's. (For those people who like to do interactive fsck's in the
3077/etc/rc scripts!?!)
3078
3079Debugfs has a few new features: the rdump command, which will do a
3080recursive dump of a directory and all of its contents, and the lcd
3081command which does a local chdir (much like the ftp command of the
3082same name). In addition, the debugfs program and the open_filesystem
3083command now takes three new options: -b and -s, which allows the
3084blocksize and superblock location to be specified, and the -c option
3085which is used in catastrophic situations where the block group
3086descriptors are corrupt. If the -c option is specified, debugfs will
3087skip trying to read in the block and inode bitmaps.
3088
3089Debufs's lsdel command was fixed to handle bad blocks in the inode
3090table.
3091
3092A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
30934 digit years.
3094
3095General improvements in error messages
3096
3097 - Mke2fs prints a sane error message if the partition size is zero
3098 (usually because the partition table wasn't reread by the
3099 kernel due to the partition being busy), instead of "invalid
3100 argument passed to ext2 library while initializing superblock".
3101
3102 - Fsck now prints more self-explanatory message if an invalid UUID=
3103 or LABEL= specification is passed to it.
3104
3105UUID library changed to use the LGPL.
3106
3107Fixed a bug in the UUID library where very rapid calls to the
3108time-based UUID generator could cause duplicate UUID's to be returned.
3109This was not a problem for e2fsprogs, but it could be a problem for
3110other users of the library.
3111
3112Make the UUID library more robust in the face of missing or an
3113improper /dev/urandom or /dev/random files.
3114
3115Added some random portability fixes for Solaris.
3116
3117Some minor man page updates.
3118
3119Fixed a memory leak in the ss library.
3120
3121
3122Programmer's notes:
3123-------------------
3124
3125We now try to use lseek64 and open64 from the LFS if possible.
3126
3127The 3rd parameter in e2p's print_flags is now a flags word, instead of
3128a boolean option.
3129
3130The mark and unmark bitmap functions now return the previous state of
3131the bit that was being changed, which is useful for some speed
3132optimizations.
3133
3134The following functions have been added to enhance the badblocks list
3135handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3136ext2fs_badblocks_equal.
3137
3138The ext2 header files now have the latest journalling fields to the
3139superblock.
3140
3141The ext2fs_mkdir function in libext2fs now properly backs out of error
3142conditions robustly.
3143
3144Cleaned up makefiles:
3145 - to cleanly compile with the -j flag.
3146 - so distclean removes all generated files.
3147 - so in case of an error while installing header files, the make aborts.
3148
3149Fix test_script so that it works correctly when compiling in the
3150source directory.
3151
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003152The random UUID generation routine has been made slightly better in
3153the case where /dev/random doesn't exist. (Use of randomly-based UUID
3154is still not recommended if /dev/random doesn't exist, however; it's
3155better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00003156
3157Clean up the build process so it's more friendly in case of missing
3158directories.
3159
3160The ext2fs header file can now be #include'd into C++ programs.
3161
3162The e2p.h header file is now installed.
3163
3164Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3165
3166
3167
Theodore Ts'o24ded091999-11-10 15:56:16 +00003168E2fsprogs 1.18 (November 10, 1999)
3169==================================
3170
3171Fix a core dumping bug in e2fsck if an imagic inode is present or
3172(more rarely) if the filesystem is badly corrupted enough that e2fsck
3173has to restart pass 1 processing. E2fsck now closes the filesystem
3174before freeing a large number of its data structures, so in the case
3175of future memory faults, at least the fixed filesystem will be fully
3176written out.
3177
3178If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3179imagic inode, it will offer to clear the imagic flag.
3180
3181E2fsck will now offer to clear the immutable flag on special files
3182(device/socket/fifos) when running it in non-preen mode.
3183
3184E2fsck will now set the filetype when creating /lost+found, and when
3185connected orphaned inodes to /lost+found.
3186
3187Debugfs's ncheck and icheck commands now handles the case where there
3188are bad blocks in the inode table without bombing out.
3189
3190The badblocks list processing code has been made more efficiently for
3191appending a large number of (ordered) badblocks to the badblocks list.
3192
3193Some minor man page updates.
3194
3195Fsck now allows interactive e2fsck's when using fsck -As (not a common
3196mode, but some people like to do this in boot scripts for silly reasons).
3197
3198Programmer's notes:
3199-------------------
3200
3201The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3202with the problem code convention.
3203
3204The badblocks list regression test program has been updated to work
3205with previously made API name changes.
3206
3207The ext2fs_free() command now uses the new badblocks API to avoid
3208using the compatibility layer.
3209
3210Added new regression test cases; the run_e2fsck test script now
3211supports the ability for a test case to run a prepratory command
3212before running e2fsck.
3213
Theodore Ts'o28e11941999-10-26 18:17:20 +00003214E2fsprogs 1.17 (October 26, 1999)
3215=================================
3216
3217Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3218infinite loop.
3219
3220Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3221thus potentially causing problems if a binary UUID contained a NULL
3222character.
3223
3224E2fsck now uses stricter checks for directory entries in pass 2:
3225zero-length filenames are not allowed; neither are 8 byte long
3226directory entries.
3227
3228The debugfs "dirty" command now clears the filesystem valid bit.
3229(Previously this just set the dirty-as-in-needs-writing-out-to-disk
3230bit in the in-core superblock image. The new functionality is more
3231what the user expects, and is more useful.)
3232
3233Added a debugging hook to test parallel fsck; if the environment
3234variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3235will be checked in parallel when they normally would not be.
3236
3237Programmer's notes:
3238-------------------
3239
3240Fixed some #ifdef's for compilation under the Hurd OS.
3241
3242Fixed minor W2K compatibility problems.
3243
3244Fixed some miscellaneous GCC warnings.
3245
3246
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00003247E2fsprogs 1.16 (October 22, 1999)
3248=================================
3249
3250Fixed a race condition bug in fsck; when printing a progress bar, if
3251checking multiple filesystems in parallel, it was possible for fsck to
3252send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3253handler, which would cause it to terminate with a signal 10.
3254
3255E2fsck now properly handles filesystems that have the
3256INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3257filesystem into using or not using FILETYPE feature.
3258
3259E2fsck now properly handles filesystems that have the IMAGIC feature
3260turned on (this is used on Linux AFS servers).
3261
3262The mke2fs program now creates filesystems that have the filetype and
3263sparse_superblock features enabled by default, unless it is run on a
3264pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3265so there is now a new flag -O which allows the user to specify with
3266which features she would like to create the filesystem; "mke2fs -O
3267none" will create a filesystsem compatible with 2.0 kernels.
3268
3269The tune2fs program now has a -O option which allows the user to set
3270and reset "safe" filesystem features. Currently, the only ones which
3271allows to be modified are the filetype and sparse_superblock features.
3272Note setting or clearing either feature will require running e2fsck on
3273the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3274requires that there is enough free space on the filesystem for the
3275extra superblocks which will be created by e2fsck.)
3276
3277Debugfs can now set and print filesystem features in the superblock
3278using the "features" command. Dumpe2fs will print out the complete
3279set of features when listing the superblock.
3280
3281Dumpe2fs has new options -f (force) and -h (header-only).
3282
3283Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3284message to come up. This could happen when decrementing or
3285incrementing a link count could result in an overflow.
3286
3287Fixed a bug in e2fsck where the block count on the lost+found
3288directory would not be properly incremented when the directory was
3289expanded to the point where an indirect block needed to be allocated.
3290
3291E2fsck now makes some additional sanity checks on the superblock to
3292avoid crashing or giving a memory allocation error if some of the
3293values in the superblock are unresonable (but the superblock otherwise
3294looks valid).
3295
3296Fixed a bug in e2fsck where a very badly corrupted filesystem might
3297require two passes to completely fix the filesystem. This happened if
3298an inode claimed blocks that was part of the filesystem metadata
3299(typically, when garbage was written into an inode table or indirect
3300block, since this kind of filesystem corruption normally doesn't
3301happen otherwise).
3302
3303On the Alpha, glibc declares st_flags although it isn't actually used;
3304the configure script was improved to detect this case so that
3305e2fsprogs can avoid using the non-functional stat field.
3306
3307The manual pages were updated to use a more consistent formatting
3308style consistent with standard Unix man pages. Mke2fs's man page
3309added documentation for a few previously undocumented options.
3310
3311Fixed minor display bugs in tune2fs and mke2fs.
3312
3313Programmer's notes:
3314-------------------
3315
3316Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
3317
3318Added features to parse and print feature strings into the e2p library.
3319(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
3320
3321ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
3322whose directory entries contain proper filetype information if the
3323filesystem supports it.
3324
3325ext2fs_link() now uses the low 3 bits of its flags parameter to pass
3326the directory entry filetype information. This is used to set the
3327directory entry filetype information if the filesystem supports it.
3328
3329Fixed a bug in ext2fs_expand_dir() where the block count in a
3330directory's inode would not be properly incremented when the directory
3331was expanded to the point where an indirect block needed to be
3332allocated.
3333
3334
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003335E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003336==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003337
3338Add configuration checks so that e2fsprogs will compile cleanly on
3339Linux 2.3 kernels that have renamed i_version to i_generation.
3340
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003341E2fsck now prints a progress/completion bar (and not just a simple
3342spinner) if the -C0 option is requested or if it receives a SIGUSR1
3343signal. Fsck will automatically manage the (potentially muliple)
3344e2fsck processes to print completion bars if it is given a -C option,
3345with the right thing happening if multiple filesystems are being
3346checked in parallel.
3347
3348Mke2fs now has better automatic hueristics to determine the filesystem
3349parameters to be used for a particular filesystem. Added a new option
3350-T which allows the user to specify how the filesystem is to be used,
3351which helps mke2fs do a better job selecting the filesystem parameters.
3352
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003353Mke2fs now creates revision 1 filesystems by default, and with the
3354sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00003355not understood by Linux 2.0 kernels, so they will only allow read-only
3356mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003357
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003358Fix bug where if /dev/null couldn't be opened (should never happen),
3359e2fsck would hang in a tight loop.
3360
3361Make e2fsck handle the case where /lost+found isn't a directory.
3362
3363E2fsck now uses mallinfo if it exists to get accurate statistics about
3364its memory usage.
3365
3366Fix bug in e2fsck where it wouldn't check to see if a disconnected
3367inode had any problems before connecting it to /lost+found.
3368
3369Add check to e2fsck so it makes sure that total number of inodes in
3370the filesystem is a sane number.
3371
3372Fix fencepost error when clearing an the end of the block bitmap which
3373caused the last block in the bitmap not to get cleared.
3374
3375Cleaned up a number of messages in e2fsck:
3376 * The message "Group's #'s copy of the group descriptor..."
3377 was fixed so that the correct number would be displayed.
3378 * Added missing space in the "disk write-protected" error messsage
3379 * Cleaned up the error message printed when a non-interactive
3380 e2fsck needs to abort a check because the filesystem
3381 appears to be mounted.
3382
3383Added a new command-line utility, uuidgen, which will create and print
3384a UUID.
3385
3386Make debugfs's icheck command more robust by checking to make sure an
3387inode has valid blocks before interarting over the inode's blocks.
3388
3389UUID generation now uses a random-based scheme whenever possible to
3390prevent potential privacy problems.
3391
3392Man pages for all of the UUID functions in the lirbary were added.
3393
3394Fixed bug in fsck so it won't coredump if a filesystem not in
3395/etc/fstab is given to it.
3396
3397Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
3398that most of the other mount utilities understands.
3399
3400Mke2fs will make a filesystem even if it appears mounted if the force
3401option is given.
3402
3403Dumpe2fs has new command-line options which allow a filesystem expert
3404to specify the superblock and blocksize when opening a filesystem.
3405This is mainly useful when examining the remains of a toasted
3406filesystem.
3407
3408The badblocks program has been updated to display correctly on disks
3409with large block numbers.
3410
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003411The badblocks program no longer gives spurious errors when errors
3412occur on non-block boundaries, which is common if the blocksize is
3413larger than 1k.
3414
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003415Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
3416MKE2FS_SYNC environment variable is set. This is to work around a VM
3417bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003418to trigger it even using a 2.2 kernel, but hopefully it will not be
3419needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003420
3421Fixed miscellaneous documentation and man pages.
3422
3423Programmer's notes:
3424-------------------
3425
3426Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
3427in e2fsck's pass1.c really should have been static.
3428
3429The return value of the uuid_compare() function was changed to make it
3430match with the convetions used by strcmp, memcmp, and Paul Leach's
3431UUID sample document.
3432
3433The "make depend" process has now been made more automated; it now
3434automatically word-wraps the dependencies, and only replaces source
3435Makefile.in if there has been a change in the dependencies. Also, a
3436top-level "make depend" now recurses through all the subdirectories
3437automatically.
3438
3439The Makefile in .../util has been changed so that subst is built using
3440the native C compiler during a cross-compilation, since the subst
3441program is only used during the build process. Also add an explicit
3442rule to build util/subst by cd'ing to the correct directory and
3443running Makefile.
3444
3445The man directories are defined in terms mandir, so that the configure
3446script can override the location of the manual pages.
3447
3448The config files have been updated to recognize new machine types for
3449both the i386 and alpha families.
3450
3451Fsck has been modified so that it will accurately create an
3452fsck_instance even when the noexecute flag is set. This allows for
3453accurate debugging of the fsck pass structure. Also, when the verbose
3454flag is given twice, fsck will print debugging information about when
3455fsck is waiting for jobs to finish.
3456
3457
Theodore Ts'o14790ed1999-01-12 23:32:52 +00003458E2fsprogs 1.14 (January 9, 1999)
3459================================
3460
3461Fix the fstab parsing code so that it can handle blank lines and
3462comment characters. Also, missing pass numbers need to be treated as
3463zero.
3464
3465Fixed a bug in e2fsck where under some circumstances (when e2fsck
3466needs to restart processing after fixing an egregious inconsistency)
3467it would try to access already freed memory.
3468
3469E2fsck now prints non-printable characters in directory entries and
3470pathnames using '^' and 'M-' notation.
3471
3472Fixed chattr so that it will ignore symbolic links when doing
3473recursive descent traversals. For both chattr and lsattr, no longer
3474print the version string unless the -V option is given.
3475
3476Allow the system administrator to directly specify the number of
3477inodes desired in the filesystem, for some special cases where this is
3478necessary.
3479
3480Fix portability problems so that e2fsprogs can be compiled under Linux
34811.2 systems and Solaris systems.
3482
3483Update the config.guess file with a more recent version that will
3484identify newer Linux platforms.
3485
3486Programmer's notes
3487------------------
3488
3489Ext2fs_read_inode and ext2fs_write_inode will now return an error if
3490an inode number of zero is passed to them.
3491
Theodore Ts'o556ad131998-12-19 08:10:58 +00003492E2fsprogs 1.13 (December 15, 1998)
3493==================================
3494
3495Fixed a bug in debugfs where an error messages weren't getting printed
3496when the ext2 library routines to read inodes returned errors in the
3497stat, cmri and rm commands.
3498
3499Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
3500provided, it won't create an inode table smaller than the minimum
3501number of inodes required for a proper ext2 filesystem.
3502
3503Fsck now parses the /etc/fstab file directly (instead of using
3504getmntent()), so that it can distinguish between a missing pass number
3505field and pass number field of zero. This caused problems for
3506diskless workstations where all of the filesystems in /etc/fstab have
3507an explicit pass number of zero, and fsck could not distinguish this
3508from a /etc/fstab file with missing pass numbers.
3509
3510E2fsck will create a /lost+found directory if there isn't one in the
3511filesystem, since it's safer to create the lost+found directory before
3512it's needed.
3513
3514Fixed e2fsck so that it would detect bogus immutable inodes which
3515happen to be sockets and FIFO files, and offer to clear them.
3516
3517If a filesystem has multiple reasons why it needs to be checked, and
3518one of the reasons is that it is uncleanly mounted, e2fsck will print
3519that as the reason why the filesystem is being checked.
3520
3521Cleaned up the output routines of mke2fs so that it doesn't overflow
3522an 80 column display when formating really big filesystems.
3523
3524Added a sanity check to e2fsck to make sure that file descriptors 0,
35251, 2 are open before opening the hard disk. This avoids a problem
3526where a broken program might exec e2fsck with those file descriptors
3527closed, which would cause disastrous results if the kernel returns a
3528file descriptor for the block device which is also used by FILE *
3529stdout.
3530
3531Fixed up the e2fsck progress reporting functions so that the values
3532reliably reach 100% at the completion of all of the e2fsck passes.
3533
3534Fixed minor documentation bugs in man pages and usage messages.
3535
3536Programmer's notes:
3537-------------------
3538
3539Fixed a number of lint warnings in the ext2fs library and potential
3540portability problems from other OS's header files that might define
3541CPP macros for names like "max" and "min".
3542
3543ext2fs_badblocks_list_add() has been made more efficient when it needs
3544to grow the bad blocks list.
3545
3546Fixed a bug in e2fsck which caused it to dereference a freed pointer
3547just before exiting.
3548
3549Fixed the substition process for generating the mk_cmds and compile_et
3550scripts so that they will work outside of the build tree.
3551
3552Add sanity check to e2fsck so that if an internal routine
3553(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
3554and causing a core dump. This should never happen, but...
3555
Theodore Ts'oa5696711998-07-09 05:38:07 +00003556E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00003557==================================
3558
3559E2fsprogs now works with glibc (at least with the version shipped wtih
3560RedHat 5.0). The ext2fs_llseek() function should now work even with
3561i386 ELF shared libraries and if llseek() is not present. We also
3562explicitly do a configure test to see if (a) llseek is in libc, and
3563(b) if llseek is declared in the system header files. (See standard
3564complaints about libc developers don't understand the concept of
3565compatibility with previous versions of libc.)
3566
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003567The ext2fs library now writes out the block group number in each of
3568the superblock copies. This makes it easier to automatically
3569determine the starting block group of the filesystem when the block
3570group information is trashed.
3571
3572Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00003573which means that e2fsprogs will ignore the high 8 bits of the
3574directory entry's name_len field, so that it can be used for other
3575purposes.
3576
3577Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
3578E2fsprogs will now support filesystems with 64-bit sized files.
3579
3580Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
3581
Theodore Ts'o21d53851998-02-21 03:14:50 +00003582Added new program "e2label", contributed by Andries Brouwer. E2label
3583provides an easy-to-use interface to modify the filesystem label.
3584
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00003585Fixed bug so that lsattr -v works instead of producing a core dump.
3586
Theodore Ts'o21d53851998-02-21 03:14:50 +00003587Fixed a minor bug in mke2fs so that all groups with bad superblock
3588backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00003589
3590Mke2fs will check the size of the device, and if the user specifies a
3591filesystem size larger than the apparent size of the device it will
3592print a warning message and ask if the user wants to proceed.
3593
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003594E2fsck has a new option -C, which sends completion information to the
3595specified file descriptor. For the most part, this is intended for
3596programs to use, although -C 0 will print a spinning character to the
3597stdout device, which may be useful for users who want to see something
3598happening while e2fsck goes about its business.
3599
Theodore Ts'o21d53851998-02-21 03:14:50 +00003600Fixed a bug in e2fsck which could cause a core dump when it needs to
3601expand the /lost+found directory, and sometimes the bitmaps haven't
3602been merged in. Also fixed a related bug where ext2fs_write_dir_block
3603was used to write out a non-directory block. (Which would be bad on a
3604non-Intel platform with byte swapping going on.)
3605
3606Fixed bug in e2fsck where it would print a "programming error" message
3607instead of correctly identifying where a bad block was in used when
3608the bad block was in a non-primary superblock or block group
3609descriptor. Also fixed a related bug when sparse superblocks are in
3610use and there is a bad block where a superblock or block group
3611descriptor would have been in a group that doesn't include a
3612superblock.
3613
3614Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
3615the block group descriptor table is corrupt, it was possible to try to
3616allocate a huge array, fail, and then abort e2fsck.
3617ext2fs_get_num_dirs() now sanity checks the block group descriptor,
3618and subsitutes reasonable values if the descriptors are obviously bogus.
3619
3620If e2fsck finds a device file which has the immutable flag set and the
3621i_blocks beyond the normal device number are non-zero, e2fsck will
3622offer to remove it, since it's probably caused by garbage in the inode
3623table.
3624
3625When opening a filesystem, e2fsck specially checks for the EROFS error
3626code, and prints a specific error message to the user which is more
3627user friendly.
3628
3629If the filesystem revision is too high, change the e2fsck to print
3630that this is either because e2fsck is out of date, or because the
3631superblock is corrupt.
3632
3633E2fsck now checks for directories that have duplicate '.' and '..'
3634entries, and fixes this corruption.
3635
3636E2fsck no longer forces a sync of the filesystem (with attendant sleep
3637calls) at all times. The ext2fs_flush() function now performs a sync
3638only if it needed to write data blocks to disk.
3639
3640Fixed a minor bug in e2fsck's pass1b's file cloning function, where
3641certain errors would not be properly reported.
3642
3643Updated and expanded a few points in the man pages which users
3644complained wheren't explicit enough.
3645
3646Added special case byte-swapping code if compiling on the PowerPC, to
3647accomodate the strange big-endian variant of the ext2 filesystem that
3648was previously used on the PowerPC port.
3649
3650
3651Programmer's notes:
3652-------------------
3653
3654Removed C++ keywords from the ext2fs libraries so that it could be
3655compiled with C++.
3656
3657E2fsck's internal organization has now been massively reorganized so
3658that pass*.c don't have any printf statements. Instead, all problems
3659are reported through the fix_problem() abstraction interface. E2fsck
3660has also been revamped so that it can be called as a library from a
3661application.
3662
3663Added new fileio primitives in libext2fs for reading and writing
3664files on an unmounted ext2 filesystem. This interface is now used by
3665debugfs.
3666
3667Added a new libext2fs function for mapping logical block numbers of
3668a file to a physical block number.
3669
3670Added a new libext2fs function, ext2fs_alloc_block(), which allocates
3671a block, zeros it, and updates the filesystem accounting records
3672appropriately.
3673
3674Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
3675sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
3676
3677The libext2fs functions now use a set of memory allocation wrapper
3678functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
3679instead of malloc, free, and resize. This makes it easier for us to
3680be ported to strange environments where malloc, et. al. aren't
3681necessarily available.
3682
3683Change the libext2fs fucntion to return ext2-specific error codes
3684(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
3685and depending on the existence of system error codes (such as EEXIST
3686and ENOENT).
3687
3688Renamed io.h to ext2_io.h to avoid collision with other OS's header
3689files.
3690
3691Add protection against ext2_io.h and ext2fs.h being included multiple
3692times.
3693
3694The types used for memory lengths, etc. have been made more portable.
3695In generla, the code has been made 16-bit safe. Added Mark
3696Habersack's contributed DOS disk i/o routines.
3697
3698Miscellaneous portability fixes, including not depending on char's
3699being signed.
3700
3701The io_channel structure has a new element, app_data, which is
3702initialized by the ext2fs routines to contain a copy of the filesystem
3703handle.
3704
3705ext2fs_check_directory()'s callback function may now return the error
3706EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
3707really do the checking, despite the presence of the callback function.
3708
3709
Theodore Ts'obc210071997-06-17 05:41:36 +00003710E2fsprosg 1.11 (June 17, 1997)
3711==============================
3712
3713Fixed e2fsck to detect (previously ignored) conflicts between the
3714superblock or block group descriptors and block bitmaps, inode
3715bitmaps, and inode tables.
3716
3717Fixed bug in e2fsck so that when the message printed out when a block
3718or inode bitmap conflicts with other data, it has the correct group
3719number.
3720
3721Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
3722to badblocks. This meant that not all of the filesystem was being
3723tested for bad blocks!
3724
3725Fixed an array boundary overrun case which cropped up in
3726ext2fs_badblocks_list_test when a user tried running "mke2fs -c
3727-b 4096".
3728
3729Adjusted the number of columns printed by mke2fs when displaying the
3730superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00003731really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00003732
3733Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
3734dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
3735fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
3736
3737Programmer's notes:
3738-------------------
3739
3740Fixed install rule in lib/ss so that ss_err.h is actually getting
3741installed.
3742
3743Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
3744bassed back to the caller.
3745
3746Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
3747setting the current inode number (which meant this function wasn't
3748working at all).
3749
3750Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
3751blocks in the bitmap when increasing the size of the bitmap.
3752
3753Changed the initial number of blocks allocated by ext2fs_init_dblist()
3754to be more realistic.
3755
3756Added a new function ext2fs_allocate_group_table, which sets up the
3757group descriptor information (and allocates inode and block bitmaps,
3758and inode tables for a particular group). The function was created by
3759factoring out code form ext2fs_allocate_tables().
3760
3761Added a new function ext2fs_move_blocks which takes a bitmap of the
3762blocks to be moved, and moves them to another location on the
3763boardboard.
3764
3765Make the unix_io channel's io_channel_flush implementation calls sync()
3766to to flush the kernel buffers to disk.
3767
3768Added a new function ext2fs_dblist_count returns the number of
3769directory blocks in dblist.
3770
3771
Theodore Ts'oae851481997-04-29 18:13:24 +00003772E2fsprogs 1.10 (April 24, 1997)
3773===============================
3774
3775Mke2fs once again defaults to creating revision #0 filesystems, since
3776people were complaining about breaking compatibility with 1.2 kernels.
3777Warning messages were added to the mke2fs and tune2fs man pages that
3778the sparse superblock option isn't supported by most kernels yet (1.2
3779and 2.0 both don't support parse superblocks.)
3780
3781Added new flag to mke2fs, -R <raid options>, which allows the user to
3782tell mke2fs about the RAID configuration of the filesystem. Currently
3783the only supported raid option is "stride" which specifies the width
3784of the RAID stripe.
3785
3786Fixed bug in e2fsck where pass1b would bomb out if there were any
3787blocks marked bad in the inode table.
3788
3789Fixed rare bug in mke2fs where if the user had a very unlucky number
3790of blocks in a filesystem (probability less than .002) the resulting
3791filesystem would be corrupt in the last block group.
3792
3793Fixed bug where if e2fsck tried to allocate a block to fix a
3794filesystem corruption problem and the filesystem had no free blocks,
3795ext2fs_new_block() would loop forever.
3796
3797The configure script now checks explicitly to see if "-static" works,
3798since that can't be assumed to be true --- RedHat doesn't install
3799libc-static by default.
3800
3801Fixed bug in libext2's block iterator functions where under some
3802cirmcustances, file with holes would cause the bcount parameter to the
3803callback function to be incorrect. This bug didn't affect any of
3804e2fsprogs programs, but it was discovered by Paul Mackerras, the
3805author of the PPC boot loader.
3806
3807Removed use of static variables to store the inode cache in libext2fs.
3808This caused problems if more than one filesystem was accessed via
3809libext2fs (static variables in libraries are generally a bad idea).
3810Again, this didn't affect e2fsprogs programs, but it was discovered by
3811Paul Mackerras.
3812
3813Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
3814will compile cleanly with 1.2.13 kernels (even with a.out shared
3815libraries!)
3816
3817Programmer's notes:
3818-------------------
3819
3820Added new functions to duplicate an ext2 filesystem handle, and its
3821associated substructure. New functions: ext2fs_dup_handle(),
3822ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
3823Other structures, such as the io_channel and the inode_cache, now have
3824a ref count so that they only get freed when they are no longer used
3825by any filesystem handle. (These functions were added as part of the
3826development effort for an ext2 resizer).
3827
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00003828E2fsprogs 1.09 (April 14, 1997)
3829===============================
3830
3831Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
3832accidentally introduced in the 1.08 release. The overhead calculation
3833was accidentally removed, which caused ext2fs_initialize() to not
3834notice when the filesystem size needed to be adjusted down because
3835there wasn't enough space in the last block group.
3836
3837Fixed bug in version parsing library routine; it was always parsing
3838the library version string, instead of using the passed-in string.
3839
3840Clarified chattr man page.
3841
Theodore Ts'o24757fa1997-04-29 17:39:27 +00003842E2fsprogs 1.08 (April 10, 1997)
3843===============================
3844
3845E2fsck 1.07 was very slow when checking very large filesystems with a
3846lot of files that had hard links (i.e., news spools). This was fixed
3847by seriously revamping the icount abstraction. Added a formal test
3848suite for the icount abstraction.
3849
3850Debugfs now has a "-l" option to the "ls" command, which lists the
3851inode number, permissions, owner, group, size, and name of the files
3852in the directory.
3853
3854Fix a bug in e2fsck where when a directory had its blocks moved to
3855another location during the pass 1b processing, the directory block
3856list wasn't updated, so pass 2 wouldn't check (and correct) the
3857correct directory block.
3858
3859E2fsck will now treat inodes which contain blocks which are claimed by
3860the filesystem metadata by treating them as multiply claimed blocks.
3861This way, the data in those blocks can be copied to a new block during
3862the pass 1b--1d processing.
3863
3864E2fsck will attempt to determine the correct superblock number and
3865display it in the diagnostic and warning messages if possible.
3866
3867Add support for a new (incompatible) feature, "sparse_super". This
3868feature reduces the number of blocks which contain copies of backup
3869superblocks and block group descriptors. (It is only an incompatible
3870feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
3871support a new -s option; e2fsck will recognize filesystems built with
3872this feature turned on.
3873
3874E2fsck now checks the library to make sure is the correct version,
3875using new library functions. (This helps to diagnose incorrectly
3876installed e2fsprogs distributions.)
3877
3878Dumpe2fs now prints more information; its now prints the the
3879filesystem revision number, the filesystem sparse_super feature (if
3880present), the block ranges for each block group, and the offset from
3881the beginning of the block group.
3882
3883Mke2fs now distributes the inode and block bitmap blok so that the
3884won't be concentrated in one or two disks in RAID/striping setups.
3885Also, if the user chooses a 2k or 4k block group, mke2fs will try to
3886choose the largest blocks per group that be chosen. (For 2k blocks,
3887you can have up to 16384 blocks/group; for 4k blocks, you can have up
3888to 32768 blocks/group.) Previously mke2fs would not allow
3889specification of more than 8192 blocks per group, even if you were
3890using a 2k or 4k block group.
3891
3892Programmer's notes:
3893-------------------
3894
3895Added a new function ext2fs_create_icount2() which takes a "hint"
3896argument. This hint argument presets the icount array with the list
3897of inodes which actually need to be in the icount array. This really
3898helps to speed up e2fsck.
3899
3900Added a new function ext2fs_icount_validate() which checks the rep
3901invariant for the icount structure. This is used mostly for testing.
3902
3903The error mesasage given when a bad inode number is passed to
3904test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
3905EXT2FS_UNMARK_ERROR).
3906
3907Added a new function ext2fs_set_dir_block which sets the block of a
3908dblist entry, given the directory inode and blockcnt.
3909
3910Added a new function ext2fs_get_library_version() which returns the
3911current library version, and ext2fs_parse_version_string() which
3912returns a version number based on a e2fsprogs version string.
3913
3914The icount functions will return EINVAL if the passed in inode number
3915is out of bounds.
3916
Theodore Ts'o21c84b71997-04-29 16:15:03 +00003917E2fsprogs 1.07 (March 9, 1997)
3918==============================
3919
3920E2fsck is now uses much less memory when checking really large
3921filesystems (or rather, filesystems with a large number of inodes).
3922Previously a filesystem with 1 million inodes required 4 megabytes of
3923memory to store inode count statistics; that storage requirement has
3924now been reduced to roughly half a megabyte.
3925
3926E2fsck can now properly deal with bad blocks appearing inside the
3927inode table. Instead of trying to relocate the inode table (which
3928often failed because there wasn't enough space), the inodes in the bad
3929block are marked as in use.
3930
3931E2fsck will automatically try to use the backup superblocks if the
3932primary superblocks have a bad magic number or have missing meta-data
3933blocks (or meta-data blocks which are out of range).
3934
3935E2fsck's pass 3 has been made more efficient; most noticeable on
3936filesystems with a very large number of directories.
3937
3938Completely revamped e2fsck's system of printing problem reports. It
3939is now table driven, to make them more easily customizeable and
3940extendable. Error messages which can be printed out during preen mode
3941are now one line long.
3942
3943Fixed e2fsck's filesystem swapping code so that it won't try to swap
3944fast symbolic links or deleted files.
3945
3946Fixed e2fsck core dumping when fixing a filesystem which has no
3947directories (not even a root directory).
3948
3949Added a check to e2fsck to make sure that the length of every
3950directory entry is a multiple of 4 (since the kernel complains if it
3951isn't).
3952
3953Added a check to e2fsck to make sure that a directory entry isn't a
3954link to the root directory, since that isn't allowed.
3955
3956Added a check to e2fsk to now make sure the '.' and '..' directory
3957entries are null terminated, since the 2.0 kernel requires it.
3958
3959Added check to write_bitmaps() to make sure the superblock doesn't get
3960trashed if the inode or block bitmap is marked as being block zero.
3961
3962Added checking of the new feature set fields in the superblock, to
3963avoid dealing with new filesystem features that this package wasn't
3964set up to handle.
3965
3966Fixed a fencepost error in ext2fs_new_block() which would occasionally
3967try to allocate a block beyond the end of a filesystem.
3968
3969When the UUID library picks a random IEEE 802 address (because it
3970can't find one from a network card), it sets the multicast bit, to
3971avoid conflicting with a legitimate IEEE 802 address.
3972
3973Mke2fs now sets the root directory's owner to be the real uid of the
3974user running mke2fs. If the real uid is non-zero, it also sets
3975the group ownership of the root directory to be the real group-id of
3976the user running mke2fs.
3977
3978Mke2fs now has more intelligent error checking when it is given a
3979non-existent device.
3980
3981When badblocks is given the -vv option, it now updates the block that
3982it is currently testing on every block.
3983
3984Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
3985currently correctly if PATH wasn't already set.
3986
3987Shared libraries now built with dependencies. This allows the shared
3988library files to be used with dlopen(); it also makes the transition
3989to libc 6 easier, since ld.so can tell which libc a particular shared
3990library expects to use.
3991
3992Programmer's notes:
3993-------------------
3994
3995Added new abstraction (defined in dblist.c) for maintaining a list of
3996blocks which belongs to directories. This is used in e2fsck and other
3997programs which need to iterate over all directories.
3998
3999Added new functions which test to see if a contiguous range of blocks
4000(or inodes) are available. (ext2fs_*_bitmap_range).
4001
4002Added new function (ext2_inode_has_valid_blocks) which returns true if
4003an inode has valid blocks. (moved from e2fsck code).
4004
4005Added new function (ext2fs_allocate_tables) which allocates the
4006meta-data blocks as part of initializing a filesystem. (moved from
4007mke2fs code).
4008
4009Added a new I/O manager for testing purposes. It will either allow a
4010program to intercept I/O requests, or print debugging messages to
4011trace the activity of a program using the I/O manager.
4012
4013The badblocks_list functions now store the bad blocks in a sorted
4014order, and use a binary search to speed up badblocks_list_test.
4015
4016The inode scan function ext2fs_get_next_inode() may now return a soft
4017error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
4018those cases where part of an inode table is missing or there is a bad
4019block in the inode table.
4020
4021Added a new function (ext2fs_block_iterate2) which adds new arguments to
4022the callback function to return a pointer (block and offset) to the
4023reference of the block.
4024
4025Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
4026application to jump to a particular block group while doing an inode
4027scan.
4028
4029The badblocks list functions were renamed from badblocks_* to
4030ext2fs_badblocks_*. Backwards compatibility functions are available
4031for now, but programs should be modified to use the new interface.
4032
4033Some of the library functions were reorganized into separate files to
4034reduce the size of some programs which statically link against the
4035ext2 library.
4036
4037Put in some miscellaneous fixes for the Alpha platform.
4038
Theodore Ts'o5c576471997-04-29 15:29:49 +00004039
4040E2fsprogs 1.06 (October 7, 1996)
4041================================
4042
4043Fixed serious bug in e2fsck: if the block descriptors are bad, don't
4044smash the backup copies in ext2fs_close(). (The problem was that when
4045e2fsck -p discovered the problem, while it was closing the filesystem
4046and exiting, it was also blowing away the backup superblocks on the
4047disk, which was less than friendly.) We now make it the case that we
4048only write out the backup superblock and the back block descriptors if
4049the filesystem is completely free from problems.
4050
4051Fixed a bug in block_interate in the lib/ext2fs library which caused
4052e2fsck to fail on GNU Hurd-created filesystems.
4053
4054Add support for Linux/FT's bootloader, which actually uses
4055EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
4056to clear the inode.
4057
4058Add support for the "A" (no atime update) attribute. (Note: this
4059attribute is not yet in production kernels.)
4060
4061The test suite is not automatically run when doing a "make all" from
4062the top level directory. Users should manually run "make check" if
4063they wish to run the test suite.
4064
4065Upon a preenhalt(), make the printed message more explicit that
4066running e2fsck "MANAULLY" means without the -p or -a options.
4067
4068In e2fsck, if a disconnected inode is zero-length, offer to clear it
4069instead of offering to connect it to lost+found.
4070
4071In e2fsck, if a filesystem was just unmounted uncleanly, and needs
4072e2fsck to be run over it, change e2fsck to explicitly display this
4073fact.
4074
4075For dumpe2fs and e2fsck, cause the -V option to print out which
4076version of the ext2fs library is actually getting used. (This will
4077help detect mismatches of using a 1.06 utility with a 1.05 library,
4078etc.)
4079
4080Programmers' notes:
4081-------------------
4082
4083EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
4084the naming convention.
4085
4086In ext2fs_initialize(), make sure the description for the inode bitmap
4087is correctly initialize.
4088
4089Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4090
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00004091E2fsprogs 1.05 (September 7, 1996)
4092==================================
4093
4094Add support for new fields in the ext2 superblock --- volume name,
4095volume UUID, and last mounted field. Dumpe2fs displays these fields,
4096tune2fs and mke2fs allows you to set them. E2fsck will automatically
4097generate a UUID for those volumes that don't have them.
4098
4099Put in support for e2fsck to recognize HURD specific ext2 features ---
4100most notably, the translator block. The e2fsprogs tools will now use
4101the creator_os field in the superblock to correctly handle different
4102OS-specific variants of the ext2 filesystem.
4103
4104E2fsck now fixes inodes which have a the deletion time set, but which
4105have a non-zero i_link_count field by offering to clear the deletion
4106time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4107ext2 kernel behavior) and offered to unlink the file.
4108
4109If e2fsck sets the clean bit, but nothing else, set the exit code
4110FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4111set the filesystem valid bit when it was previously cleared. :-) This
4112was needed to make the HURD fsck driver happy.
4113
4114If the user refuses to attach an unattached inode, e2fsck will no
4115longer set the inode's link count. Otherwise, the inode would end up
4116getting marked as unused, which might cause loss of data later.
4117
4118Make the message issued by e2fsck when the superblock is corrupt less
4119confusing for users. It now mentions that another reason for the
4120"corrupt superblock" message might be that the partition might not be
4121an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4122
4123Make the libext2 library more robuest so that e2fsck won't coredump on
4124an illegal superblock where the blocksize is zero. (f_crashdisk is
4125the test case).
4126
4127By default, create filesystems where the default checkinterval is 6
4128months (180 days). Linux servers can be robust enough that 20 reboots
4129can be a long, long time.
4130
4131Added configure flag --enable-old-bitops, which forces the bitops to
4132use the old (native) bitmask operations. By default on the sparc
4133platform, the standard ext2 bit ordering is now used.
4134
4135Added a new feature to e2fsck to byte-swap filesystems; this can be
4136used to convert old m68k filesystems to use the standard byte-order
4137storage for the superblock, inodes, and directory blocks. This
4138function is invoked by using the '-s' option to e2fsck.
4139
4140Debugfs's "dump" command has been enhanced so that it writes out the
4141exact size of the file so that the nulls at the end of the file are
4142eliminated. The command also accept a new "-p" option which will
4143attempt preserve to preserve the ownernship, permissions, and
4144file modification/access times.
4145
4146Debugfs has two new options, -f and -R. The -R option allows the user
4147to execute a single debugfs command from the command line. The -f
4148option allows the user to specify a "command file" containing debugfs
4149commands which will get executed.
4150
4151Dumpe2fs now pretty prints the check interval, instead of just
4152printing the check interval as a number of seconds.
4153
4154Fix bugs in debugfs: the params command when no filesystem is opened
4155no longer causes a core dump. It is now possible to unlink a file
4156when a pathame containing a '/' is specified.
4157
4158Tune2fs has a new -C option which sets the number of times the
4159filesystem has been mounted.
4160
4161Fix the chattr '-v' option so that it actually works. Chattr was
4162being buggy about the -v option parsing.
4163
4164Programmers' notes:
4165-------------------
4166
4167The directory lib/uuid contains a set of library routines to generate
4168DCE compatible UUIDs.
4169
4170Extended ext2fs_namei() to handle symbolic links. Added new function
4171ext2fs_nami_follow() which will follow last symbolic link in the case
4172where the pathname points to a sym link.
4173
4174The ext2fs_block_iterate function will now return the HURD translator
4175block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4176iterator to return data blocks only. The ext2fs.h file now defines
4177constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4178BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4179count field of the iterator callback function.
4180
4181The test script driver now takes an optional second argument, which is
4182the test case to be run. This allows you to run a test case without
4183needing to run the entire test suite.
4184
4185On Linux ELF systems, install the .so files in the correct places
4186(/usr/lib). The .so files must be stored in the same directory as the
4187.a files.
4188
4189Fixed miscellaneous HURD compilation issues with header file being
4190included in the right order.
4191
4192Fixed debugfs so that it resets optind to zero, not one, since setting
4193optind to zero is more correct.

Theodore Ts'oa4d09611997-04-29 14:28:00 +00004196E2fsprogs 1.04 (May 16, 1996)
4197=============================
4198
4199First "official" (1.03 was a limited release only) to support building
4200e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4201kernels).
4202
4203This package includes a RPM specs file, that it can be built using the
4204RedHat Package Manager.
4205
4206E2fsck now prints a hint that if there are lots of incorrectly located
4207inode bitmaps, block bitmaps, and inode table blocks, the user might
4208want to try using e2fsck -b 8193 first, to see if that fares any
4209better.
4210
4211For ext2 filesystem written with the hurd, debugfs will now print out
4212the translator field when printing an inode structure.
4213
4214Lots of miscellaneous linking/installation cleanups:
4215
4216 Libraries are now linked using a relative pathname, instead of
4217 relying on -L working correct. It doesn't, in many cases, including
4218 current versions of GNU ld. This guarantees that the build tree is
4219 linking with the right libraries, instead of the ones installed in
4220 /usr/lib.
4221
4222 Header files, man pages, and the et/ss shell scripts are now
4223 generated using a custom substitution script, instead of relying on
4224 the configure script. This prevents needless recompilation of
4225 files; in addition, the custom substitution script is much faster.
4226
4227 e2fsck may now be linked dynamically, by using the
4228 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4229 since it increases e2fsck's dependence on other files, but some
4230 people need to save disk space, and other critical programs on their
4231 systems were being linked dynamically anyway.
4232
4233 Programs such as fsck which didn't need to be linked against
4234 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4235 only link against libraries they actually need. Otherwise, those
4236 programs would require the presense of libraries that otherwise
4237 could be removed from a rescuse diskette.
4238
4239 The ss include files are now installed correctly so they can
4240 actually be used by another package.
4241
4242 If the profiling libraries are built, they are now installed on a
4243 "make install-libs".

Theodore Ts'o7f88b041997-04-26 14:48:50 +00004246E2fsprogs 1.03 (March 27, 1996)
4247===============================
4248
4249Change the m68k bit numbering for bitmasks to match the bit numbering
4250used by all other ext2 implementations. (This change was requested by
4251the m68k kernel development team.)
4252
4253Support (in-development) filesystem format revision which supports
4254(among other things) dynamically sized inodes.
4255
4256Fixed a bug in the ext2 library so that an intelligent error is
4257returned if mke2fs is run with a ridiculously small number of blocks
4258for a partition.
4259
4260Fixed a bug in the ext2 library which required that the device be
4261openable in read/write mode in order to determine its size. This
4262caused e2fsck -n to require read/write access when it was not
4263previously necessary.
4264
4265Fixed a bug in e2fsck which casued it to occasionally fail the test
4266suite depending on which version of the floating point library it was
4267using.
4268
4269Fixed a bug in e2fsck so that it now halts with a fatal error when
4270certain superblock consistency checks fail. Previously it continued
4271running e2fsck, with some potential confusing/damaging consequences.
4272
4273Added new flag to fsck which allows the root to be checked in parallel
4274with other filesytems. This is not the safest thing in the world to
4275do, but some system administrators really wanted it.
4276
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00004277Fixed -Wall flames in lib/ss.
4278
Theodore Ts'o74becf31997-04-26 14:37:06 +00004279
4280E2fsprogs 1.02 (January 16, 1996)
4281=================================
4282
4283Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4284
4285Change e2fsck to print statistics of how many non-contiguous files are
4286on the system. Note that a file which is larger than 8k blocks, it is
4287guaranteed to be non-contiguous.
4288
4289In mke2fs, print a warning message if a user tries to format a whole
4290disk (/dev/hda versus /dev/hda1). If a user really wants to format a
4291whole disk, the -F (force) option forces mke2fs to format a whole disk
4292as a filesytem.
4293
4294Fix a bug in fsck where in some cases it might start checking
4295partitions in the next pass before it finishes checking partitions in
4296the current pass. This still won't cause two partitions on the same
4297disk will be checked, so it's rarely a problem in real life.
4298
4299Patch lsattr so that it won't hang when checking a named pipe.
4300
4301Minor compilation fixes:
4302 * Fix the order of libraries that were linked in debugfs.
4303 * Allow the sources to be compiled with -ansi turned on.
