2====================================
3
4Improve time-based UUID generation. A new daemon uuidd, is started
5automatically by libuuid if necessary. This daemon is setuid to allow
6updates to /var/lib/libuuid, so the clock sequence number can be
7stored and so if the clock is set backwards, it can be detected.
8(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
9#233471)
10
11Filter out the NEEDS_RECOVERY feature flag when writing out the backup
12superblocks. This avoids e2fsck from concluding that a full
13filesystem check is required before backing up the superblock due to
14changes in the feature flags. (Addresses Debian Bug: #454926)
15
16Fix fsck to only treat the '#' character as a comment at the beginning
17of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
18will cause fsck to issue an bogus warning message.
19(Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
20
21Format control characters and characters with the high eighth bit set
22when printing the contents of the blkid cache, to prevent filesystems
23with garbage labels from sending escape sequences to the user's screen
24that might, for example place it in graphics mode. (Addresses Ubuntu
25Bug: #78087)
26
27Fix sign-extension problem on 64-bit systems in in the com_err
28library. (Addresses Sourceforge Bug: #1809658)
29
30Avoid division by zero error when probing an invalid FAT filesystem in
31the blkid library. (Addresses Sourceforge Bug: #1831627)
32
33Update Dutch, Polish, and Vietnamese translations from the Translation
34Project. Remove the Rwandan translation upon advice of the
35Translation Project.

37Programmer's Notes:
38-------------------
39
40Fix the libss "make check" regression test so that it works if the
41current directory is not in the user's path or if the libss shared
42library is not installed. (Addresses Sourceforge Bug: #1848974)
43
44Fixed spelling mistakes, typos, and otherwise clarified man pages.
45(Addresses Debian Bugs: #444883, #441872)

57===================================
58
59Fix a potential security vulnerability where an untrusted filesystem
60can be corrupted in such a way that a program using libext2fs will
61allocate a buffer which is far too small. This can lead to either a
62crash or potentially a heap-based buffer overflow crash. No known
63exploits exist, but main concern is where an untrusted user who
64possesses privileged access in a guest Xen environment could corrupt a
65filesystem which is then accessed by the pygrub program, running as
66root in the dom0 host environment, thus allowing the untrusted user to
67gain privileged access in the host OS. Thanks to the McAfee AVERT
68Research group for reporting this issue. (Addresses CVE-2007-5497.)
69
70Fix hueristics in blkid which could cause a disk without partitions to
71be incorrectly skipped when a loopback device is present. (Addresses
72Red Hat Bugzilla #400321.)
73
74Fix e2image so that in raw mode it does not create an image file which
75is one byte too large.
76
77Change mke2fs's usage message so it recommends the preferred -E option
78instead of the deprecated -R option.
79
80Enhance the blkid library so it will recognize squashfs filesystems.
81(Addresses Red Hat Bugzilla #305151.)
82
83Enhance e2fsck so it will force the backup superblocks to be backed up
84if the filesystem is consistent and key constants have been changed
85(i.e., by an on-line resize) or by e2fsck in the course of its
86operations.
87
88Enhance blkid's detection of FAT filesystems; so that USB disks with
89only a single bootable partition will not get missed.
90
91E2fsck will no longer mark a filesystem as invalid if it has time
92errors (i.e., if superblock mount time or last write time is in the
93future) and the user refuses to fix the problem.
94
95The Ubuntu init scripts don't properly set the system time correctly
96from hardware clock if the hardware clock is configured to tick local
97time instead of GMT time. Work around this as best as we can by
98providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
99be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
100Bug #131201.)
101
102Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
103Hat Bugzilla #151533.)
104
105Fix e2fsck so that if the superblock is corrupt, but still looks
106vaguely like an ext2/3/4 superblock, that it automatically tries to
107fall back to the backup superblock, instead of failing with a hard
108error.
109
110Make the e2fsprogs program more robust so that they will not crash
111when opening a corrupt filesystem where s_inode_size is zero.
112
113Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
114arguments are detected as such and the parse error is reported to the
115user. (Addresses Debian Bug #435381.)
116
117Change e2fsck so it will not complain if a file has blocks reallocated
118up to the next multiple of a system's page size.
119
120Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
121about (valid) filesystems where the inode table extends to the last
122block of the block group. (Addresses Red Hat Bugzilla #214765.)
123
124Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
125allocating inode tables for some relatively rare odd disk sizes.
126(Addresses Red Hat Bugzilla #241767.)
127
128Add Catalan translation and update Dutch and Swedish translations
129from the Translation Project.
130
131Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
132still had an issue when trying to figure out whether we need to
133byte-swap fast symlinks that contained extended attributes.
134
135Fixed spelling mistakes, typos, and otherwise clarified man pages.
136(Addresses SourceForge Bug #1821333.)
137
138
139Programmer's Notes:
140-------------------
141
142Fix mke2fs tests to avoid needing any significant ^M (CR) characters
143
144Add "make check" to the RPM spec file
145
146Fix "make install" and 'make unstall" in misc/Makefile.in so that it
147works correctly when the prefix is not the root directory.
148
149Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
150clena up after themselves by deleting the test.img temporary file
151after completing the test.
152
153Fixed a corner case bug ext2fs_unlink() when trying to delete the
154first directory entry in a directory block and the last directory
155entry in the previous directory block is not in use. Fortunately
156ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
157places where it is extremely unlikely to run into this corner case.
158
159Fix missing dependency which would cuase parallel builds to fail.
160(Addresses Sourceforge Bug #1842331.)
161
162Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
163calling open(O_CREATE) with a missing mode parameter.
164
165Fix the test_ss.c in lib/ss so it can be used as an example
166application program for the library as well as a regression test
167suite.
168
169Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
170are properly passed back up through the call stack.

Theodore Ts'od2dc78a2007-07-14 09:03:17 -0400172E2fsprogs 1.40.2 (July 12, 2007)
173================================
174
175A recent change to e2fsck_add_dir_info() to use tdb files to check
176filesystems with a very large number of filesystems had a typo which
177caused us to resize the wrong data structure. This would cause a
178array overrun leading to malloc pointer corruptions and segfaults.
179Since we normally can very accurately predict how big the the dirinfo
180array needs to be, this bug only got triggered on very badly corrupted
181filesystems.
182
183Fix a bug in e2fsck which caused it to incorrectly salvange
184directories when the last entry's rec_len is bogusly too big. This
185resulted in a nonsense filesystem corruption to be reported, and
186required a second run of e2fsck to fully fix up the directory.
187
188Update tune2fs man page to include more discussion of reserved blocks
189(Addresses Launchpad bug #47817)
190
191Update Turkish, Polish, Dutch, and Vietnamese PO files from the
192Translation Project

196===============================
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400197
198Fix bug which could cause libblkid to loop forever. When revalidating
199a partition where there is obsolete information in /etc/blkid.tab, we
200end up freeing a the type tag without clearing dev->bid_type, causing
201blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
202
203The Turkish translation has a bug in it where it has the translation
204of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
205@E, recursively, forever, until the stack fills up and e2fsck core
206dumps. We fix this by making e2fsck stop @-expansions after a
207recursive depth of 10, which is far more than we need.
Theodore Ts'od2dc78a2007-07-14 09:03:17 -0400208(Addresses Sourceforge Bug: #1646081)
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400209
210Compile the default mke2fs.conf into mke2fs program. People are
211getting surprised by mke2fs creating filesystems with different
212defaults than earlier versions of mke2fs if mke2fs.conf is not
213present. So we now create a built in version of mke2fs.conf file
214which is used by mke2fs if the /etc/mke2fs.conf is not present.
215(Addresses SourceforgeBug: #1745818)
216
217Improve the config/parse_types.sh helper script. Fix a potential
218security problem if e2fsprogs is built as root (as Gentoo does!). In
219addition fix the script and how it is called from the configure script
220so that it does the right thing when cross-compiling. (Fixes Gentoo
221bug: #146903)
222
223Update Vietnamese, French, and Dutch PO files from the Translation
224Project. Also created a new e2fsprogs.pot file for translator.
225
226Fix bogus strip permission errors when building under Debian. When
227building the e2fsprogs dpkg's, the dh_strip command emits a large
228number of error messages caused by the permissions not being right.
229So run dh_fixperms before running dh_strip.
Theodore Ts'o58b3df72007-07-08 20:26:51 -0400230
231Programmer's Notes:
232-------------------
233
234Add new function: profile_set_default(). This function sets the value
235of the pseudo file "<default>". If the file "<default>" had
236previously been passed to profile_init(), then def_string parameter
237will be parsed and used as the profile information for the "<default>"
238file.
239
240Fix mk_cmds's error reporting so that it is unambiguous that it is the
241mk_cmds script which is generating the error. (Obviates Gentoo patch:
242e2fsprogs-1.32-mk_cmds-cosmetic.patch)
243
244Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
245priority" environment variable that overrides all others, where as
246LANG is the lowest priorty environment variable. If LC_ALL is set, it
247doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
248the all the rest are set. This will assure that the locale when
249running the test suites is the "C" locale. (Obviates Gentoo patch:
250e2fsprogs-1.38-tests-locale.patch)

254==============================
255
256Fix divide by zero error in blkid's NTFS probing logic.
Theodore Ts'od7b64722007-06-24 17:32:47 -0400257
258Add new blkid -g option which causes the blkid cache to be garbage
259collected.
260
261Fix a bug in libblkid which could cause the internal field bid_type to
262become corrupted. Fortunately bid_type isn't used much, and bid_label
263and bid_uuid is only used by debugging code, so the impact of this bug
264was very minor.
265
266Mke2fs will now store the RAID stride value when a filesystem is
267created with a requested RAID stride, and then use it automatically in
268resize2fs.
269
270Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
271isn't too big. In some cases Lustre users have tried specifying an
272inode size of 4096 bytes, while keeping an inode ratio of one inode
273per 4096 bytes.
274
275Improve sanity check in e2fsck's algorithm for finding a backup
276superblock, so that it won't accidentally find a superblock that was
277located in the journal, and then later reject it as being not a valid
278backup superblock.
279
280Fix e2fsck get_size logic so that it will work with the Linux floppy
281driver. The Linux floppy driver is a bit different from the other
282block device drivers, in that if the device has been opened with
283O_EXCL, it disallows another open(), even if the second open() does
284not have the O_EXCL flag. (Addresses Debian Bug: #410569)
285
286Fix error checking of badblock's last-block and start-block arguments.
287(Addresses Debian Bug: #416477)
288
289Fix e2fsck so that it doesn't overwrite the backup superblocks when
290recovering a journal until the master superblock has been confirmed as
291being sane.
292
293Change the blkid library to be much more paranoid about concluding
294that a partition contains an NTFS filesystem, and fetch the UUID and
295LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
296#110138)
297
298Factor out the code which sets the default journal size and move it
299into libext2fs.
300
301Enhance e2fsck so it will recreate the ext3 journal if the original
302journal inode was cleared to due it being corrupt after finishing the
303filesystem check.
304
305Fix e2fsck so that it updates the journal inode if it is corrupted and
306the backup journal information from the superblock was successfully
307used to recover the filesystem.
308
309Fix e2fsck so that it checks all of the blocks in the journal inode
310for validity. The original code only checked the direct blocks to
311make sure the journal inode was sane. Unfortunately, if some or all
312of the indirect or doubly indirect blocks were corrupted, this would
313not be caught.
314
315Add support in blkid to detect LUKS encrypted partitions.
316
317Add extra sanity checks for extended attributes in the case where the
318size is zero but the offset is very large.
319
320Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
321and ext2fs_get_next_inode_full().
322
323Clarify the copyright licenses used by the various libraries in
324the top-level COPYING file (Red Hat Bugzilla: 166058)
325
326Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
327
328Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
329
330Remove check in e2fsck which requires EA's in inodes to be sorted;
331they don't need to be sorted, and e2fsck was previously wrongly
332clearing unsorted EA's stored in the inode structure.
333
334Allow mke2fs or tune2fs to create a substantially larger journal (up
335to 10,240,000 blocks).
336
337Fix MD superblock detection, and make sure the correct UUID is
338reported from the MD superblock.
339
340Fix a signed vs. unsigned bug in debugfs.
341
342Enhance debugfs's date parser so that it accepts integer values.
343
344Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
345file with multiply claimed blocks is hard linked. or not at all if the
346root directory contains shared blocks
347
348Enhance debugfs so it can modify the block group descriptors using the
349command set_block_group_descriptor.
350
351Improve e2fsck's reporting of I/O errors so it's clearer what it was
352trying to do when an error happens
353
354Fix a bug in in how e2fsprogs byte swaps inodes containing fast
355symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
356#232663 and LTC Bugzilla: #27634)
357
358Fix potential file descriptor leak in ext2fs_get_device_size() in an
359error case.
Theodore Ts'oa0d42542007-04-07 11:05:10 -0400360
361Add libreadline.so.5 support to libss.
362
363Impove badblocks -n/-w exclusive usage message.
364
365Fix dump_unused segfault in debugfs when a filesystem is not open
366
367Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
368
369Allow the debugfs lcd command to work w/o a filesystem being open.
370(Addresses LTC Bugzilla #27513)
371
372Fix e2fsck to clear i_size for special devices with a bogus i_blocks
373field on the first pass.
374
375Fix e2fsck to set the file type of the '..' entry when connecting
376a directory to lost+found. (Addresses Lustre Bug: #11645)
377
378Enhance e2fsck to recover directories whose modes field were corrupted
379to look like special files. This is probably only useful in
380artificial test cases, but it will be useful if we ever do the "inodes
381in directory" idea for ext4.
382
383Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
384#412614)
385
386Fix resize2fs parsing of size parameter (in sector units). This was
387actually a bug in libe2p's parse_num_blocks() function. When handling
388the 's' suffix, it was ignoring the blocksize information passed in
389from the caller and always interpreting the number in terms of a 1k
390blocksize. (Addresses Debian Bug: #408298)
391
392There was a floating point precision error which could cause e2fsck to
393loop forever on really big filesystems with a large inode count.
394(Addresses Debian Bug: #411838)
395
396Fix memory leak in ext2fs_write_new_inode()
397
398Add support for using a scratch files directory to reduce e2fsck's
399emory utilization on really big filesystems. This uses the TDB
400library. See the [scratch_files] section of the e2fsck.conf man page
401for more details.

403Fixed type-punning bug which caused dumpe2fs to crash on the Arm
404platform (Addresses Debian Bug: #397044)
405
406Add explanatory message to badblocks that -n and -w are mutually exclusive
407(Addresses Debian Bug: #371869)
408
409Allow debugfs and dumpe2fs to support fs features under development.
410
411Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
412ext2fs_open() , which allows application to open filesystes with features
413which are currently only partially supported by e2fsprogs.
414
415Allow unix_io to support offsets greater than 2G (Addresses
416SourceForge Bug: #1547922)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400417
418Fixed overflow and signed/unsigned problems caused by the number of
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500419blocks or inodes exceeding 2**31 or being close to 2**32-1.
420
421Add support for unsigned directory hash calculations with hints in the
422superblock to fix cross-architectural portability for htree
423directories with filenames where the high 8th bit is set. (Addresses
424Debian: #389772)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400425
426Fix resize2fs so that it gives user-intelligible error messages if the
427filesystem or the kernel does not support on-line resizing.
428(Addresses Debian Bug: #380548)
429
430Require mke2fs -F -F for really dangerous operations, since -F is
431needed for less dangerous operations such as creating filesystems
432images in regular files, or creating filesystems on whole block
433devices. These relatively innocuous usages should NOT be confused
434with running mke2fs on an apparently-mounted or in-use filesystem.
435
436Allow the default inode size to be specified into the mke2fs.conf
437file.
438
439Make the smallest default journal size is big enough so that on-line
440resizing should always work.
441
442Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
443#1531372)
444
445Fix debugfs coredump when lsdel is run without an open filesystem
446(Addresses Debian Bug: #378335)
447
448Fix debugfs display bug us that bytes that have the high bit set are
449displayed as "ec" instead of "ffffffec".
450
451Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
452
453Device mapper scanning wasn't working in the blkid library because the
454pathnames had an extra "/dev" when they were being probed.
455
456Add GFS/GFS2 support to the blkid library.
457
458Fix blkid support of empty FAT filesystem labels.
459
460Avoid recursing forever (or for a long time) when the blkid library
461searches for a device and there are symlinks to directories in /dev.
462
463Avoid unaligned halfword access in blkid when accessing FAT
464superblocks, as this will cause Sparc/Solaris systems to throw a
465SIGBUS error.
466
467The latest devmapper libraries requires pthreads, add -lpthreads to
468the static link libraries for e2fsck.static if devmapper is enabled.
469(Addresses Debian bug: #388718)
470
471Improve the (non-installed, for experts only) findsuper program by
472printing the uuid and label from the superblocks, as well as the
473starting and ending offsets of the filesystem given the information in
474the superblock. Omit by default printing superblocks that are likely
475found in located in an ext3 journal unless an explicit -j option is
476given.

Theodore Ts'o80dda9b2007-12-03 18:33:39 -0500478Updated Spanish, French and Dutch translations and added Catalan
479translation. (Addresses Debian bug: #411562)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400480
481Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
482determining a partition's size, since binary searching to determine
483the device doesn't work on FreeBSD.
484
Theodore Ts'od7b64722007-06-24 17:32:47 -0400485Documentation about UUID's is available in enough places, and it's
486awkward to deal with debian-legal's insanities. So I'm caving in the
487"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
488don't have do the dfsg tarball. Also remove the rule that only tried
489to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
490e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
491
492Fix the info-dir line so that the menu name does not contain a .info
493prefix. First of all, it's ugly, secondly, it causes the install-info
494command to fail to remove the com_err info file from the
495/usr/share/info/dir file when the comerr-dev package is removed and
496purged. (Addresses Debian Bug: #401711)

506Programmer's notes:
507-------------------
508
Theodore Ts'oa0d42542007-04-07 11:05:10 -0400509E2fsck now supports the %It expansion when printing a problem report.
510It will print the type of the inode in the problem context.
511
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400512Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
513(Addresses Sourceforge Bug: #1565561)
514
515Remove unused variables and other lint/gcc -Wall cleanups
516
517Add check to ext2fs_get_device_size() so it will return EFBIG for for
518filesystems contained in regular files where the filesystem image size
519is returned by stat64().
520
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500521Set local environment variables to C so mk_cmds and compile_et always
522work. (Addresses SourceForge Bug: #1532177)
523
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400524Added the 64-bit byte swapping function ext2fs_swab64().
525
526Added two new helper functions to prevent 2**31/2**32-1 overflow
527problems: ext2fs_div_ceil() and e2p_percent().
528
529Create new ext2fs library inline functions ext2fs_group_first_block()
530and ext2fs_group_last_block() in order to calculate the starting and
531ending blocks in a block group.
532
533Create the generated files read-only to remind developers not to edit them.
534
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500535Add support for autoconf 2.60 (with backwards compatibility for older
536versions of autoconf).
537
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400538Added an "make rpm" target to top-level Makefile
539
540Added various FreeBSD portability fixes.
541
542Exclude mercurial files from the RPM build tree to speed up copy/build.
543
544Use root_sysconfdir to define the locations of mke2fs.conf and
545e2fsck.conf instead of using a hard-coded /etc pathname.
546
547Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
548
549Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
550
551If diff -u is supported, use it to report test failures.
552
553Updates/improvements to RPM spec file
554
Theodore Ts'o7809bc52006-11-14 23:49:07 -0500555Add on-disk format definitions for the following new features:
556EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
557EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
558EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
559
560Add a new make target "checked-failed" in the tests directory which
561reruns any failed tests
562
563Update draft-leach-uuids-guids-01.txt with rfc4122.txt
564
Theodore Ts'oa0d42542007-04-07 11:05:10 -0400565Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
566pointer dereferences, memory leaks, etc. None were security-criticial
567problems.
568
569Fix up usage and decrement error messages in the test_icount program
570
571Add debugging code to the com_err library; if the environment variable
572COMERR_DEBUG is set to 1, print out debugging messages as error tables
573are added and removed from the com_err library. If the
574COMERR_DEBUG_FILE environment variable is set (and the process is not
575setuid) the debugging messages may be redirected to a file.
576
577Change all of the e2fsprogs programs to use the newer add_error_table()
578and remove_error_table() interfaces instead of the much older
579initialize_*_error_table() function.
580
581Add TDB support into the ext2fs library. This allows us to have a
582guaranteed library we can count on always being present so we can
583store data in an on-disk database.
584
585Add support for using TDB to store the icount data, so we don't run out
586of memory when checking really large filesystems.
587
Theodore Ts'od7b64722007-06-24 17:32:47 -0400588Change the regression test suite so that it skips empty test directories.
589
590Define the l_i_iversion field in ext2_inode. The l_i_version field is
591now defined from the old l_i_reserved1 field in the ext2 inode. This
592field will be used to store high 32 bits of the 64-bit inode version
593number.
594
595Add Makefile production rule for e2fsprogs.spec in case it gets
596deleted.
597
598Add new function profile_get_uint() to allow for a clean way to fetch
599unsigned integers from the context.
600
601Add test to make sure the ext2 superblock structure is 1024 bytes.
602
603Fix typo in name of f_dup4 regression test
604
605Add new function blkid_gc_cache() which performs a garbage collection
606pass on the /etc/blkid.tab file.
607
608The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
609general, only e2fsck (after the filesystem is clean), tune2fs, and
610resize2fs should change the backup superblocks by default. Most
611callers of ext2fs_open() should not be touching any superblock fields
612which require the backups to be touched.
613
614Add new function to libext2fs, ext2fs_default_journal_size(), which
615returns the default journal size.
616
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -0400617
Theodore Ts'o6c094752006-05-29 11:47:25 -0400618E2fsprogs 1.39 (May 29, 2006)
619=============================
Theodore Ts'o34a26112006-03-29 20:40:23 -0500620
Theodore Ts'o34a26112006-03-29 20:40:23 -0500621Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
622between 2**31 and 2**32 blocks.
623
Theodore Ts'o34a26112006-03-29 20:40:23 -0500624Change mke2fs to use /etc/mke2fs.conf as a configuration file to
625configure the filesystem features, blocksize, and inode_ratio for
626different filesystem types.
627
Theodore Ts'o6c094752006-05-29 11:47:25 -0400628Mke2fs will now create filesystems hash trees and on-line resizing
629enabled by default, based on the new /etc/mke2fs.conf file.
630
Theodore Ts'o34a26112006-03-29 20:40:23 -0500631The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
632filesystem device node in exclusive mode to prevent accidents by
633system administrators. In the case of resize2fs and mke2fs, it will
634only use exclusive mode if the filesystem is not mounted.
635
636Fixed a bug in mke2fs which caused it to to fail when creating the
637resize inode for large filesystems. (Addresses Debian Bug #346580)
638
Theodore Ts'obae55642006-05-14 17:31:48 -0400639When allocating space for the RAID filesystems with the stride
640parameter, mke2fs will now place each portion of the group's inode
641table right up after the superblock (if present) in order to minimize
642fragmentation of the freespace.
643
644Speed up mke2fs and e2fsck by writing inode and block bitmaps more
645efficiently by writing the inode and block bitmaps in one pass, thus
646reducing the number of disk seeks required.
647
Theodore Ts'o34a26112006-03-29 20:40:23 -0500648Add support for on-line resizing to resize2fs.
649
650Fix blkid library so that logic to determine whether or not a device's
651cached information in /etc/blkid.tab needs to be verified or not
652doesn't get confused by a system clock which is insane (for example,
653if the battery is dead on a Macintosh running PPC Linux. (Addresses
654Red Hat Bug: #182188)
655
656The blkid library will now store the UUID of the external journal used
657by ext3 filesystems, so that in the future, the userspace mount binary
658can use this to find the location of the external journal and pass
659this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -0500660
661E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -0500662control how various options should be handled. See the e2fsck.conf
663man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -0500664
Theodore Ts'o34a26112006-03-29 20:40:23 -0500665E2fsck now prints an explanatory message when delaying a filesystem
666check when the system is running on battery. (Addresses Debian Bug:
667#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400668
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500669E2fsck will detect if the superblock's last mount field or last write
670field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -0500671#327580) These problems will be fixed automatically in preen mode
672since Debian's boot sequence bogusly doesn't set the time correctly
673until potentially very late in the bootup process, and this can cause
674false positives which will cause users' systems to fail to boot.
675(Addresses Debian Bugs #343662 and #343645)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400676
Theodore Ts'o34a26112006-03-29 20:40:23 -0500677E2fsck now checks to see if the superblock hint for the location of
678the external journal is incorrect, and if so, offer to update it.
679(Addresses Debian Bug: #355644)
680
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400681Fix e2fsck from segfaulting on disconnected inodes that contain one or
682more extended attributes. (Addresses Debian Bug: #316736, #318463)
683
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500684E2fsck will stop and print a warning if the user tries running a
685read/write badblocks test on a read-only mounted root filesystem.
686
Theodore Ts'obae55642006-05-14 17:31:48 -0400687Fix a memory leak in e2fsck's error paths. (Thanks to Michael
688C. Thompson for pointing these out; they were originally found using
689Coverity.)
690
Theodore Ts'of3227852005-12-31 16:45:29 -0500691When resizing a file containing a filesystem, resize2fs will expand or
692truncate a file as necessary. (Addresses Debian Bug: #271607)
693
Theodore Ts'obae55642006-05-14 17:31:48 -0400694Resize2fs will now automatically determine the RAID stride parameter that
695had been used to create the filesystem, and use that for newly created
696block groups. The RAID stride parameter may also be manually specified
697on the command line using the new -S option to resize2fs.
698
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500699Fix mke2fs so that it correctly creates external journals on
700big-endian machines (such as a S/390).
701
Theodore Ts'obae55642006-05-14 17:31:48 -0400702Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
703fail to print out the journal or hash seed UUID. (Thanks to Guillaume
704Chambraud for pointing this out.)
705
706Dumpe2fs will now print the size of the journal (if present).
707
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500708Fix debugfs's set_inode_field command so it can properly set the frag,
709fsize, uid_high, gid_high, and author fields in the inode instead of
710silently failing, and so that setting the i_size actually sets i_size
711correctly.
712
713Add a new debugfs command, set_current_time, which sets fs->now so
714that regression test suites can repeatedly modify the filesystem's
715last_write fields.
716
Theodore Ts'o34a26112006-03-29 20:40:23 -0500717Fix a bug in debugfs's icheck which would incorrectly report the owner
718of an extended attribute block.
719
Theodore Ts'obae55642006-05-14 17:31:48 -0400720Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
721print a usage message when an illegal option character is given.
722
Theodore Ts'o6c094752006-05-29 11:47:25 -0400723Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
724so it won't core dump. (Addresses SourceForge bug #1424311)
725
Theodore Ts'obae55642006-05-14 17:31:48 -0400726Fix mklost+found so that it creates a full-sized directory on
727filesystems with larger block sizes.
728
729Fix a file descriptor leak in blkid library.
730
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500731Fix a display bug in "badblocks -sv" so that the done message properly
732clears the block number at the end of the test. (Addresses Debian Bug
733#322231)
734
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400735Allow fractional percentages to the -m option in mke2fs and tune2fs
736(Addresses Debian Bug: #80205)
737
738Use fstat/fstat64 in getsize.c if the the target is a regular file,
739instead of attempting to do a binary search. Fix some fd leaks in
740error cases.
741
Theodore Ts'o34a26112006-03-29 20:40:23 -0500742Add support for device mapper library to the blkid library to ensure
743that the "best" (i.e., leaf) device is probed by the blkid library.
744
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500745Fix the blkid library so that it notices when an ext2 filesystem is
746upgraded to ext3.
747
748Improve the blkid's library VFAT/FAT detection; it now understands
749labels stored in the root directory, and is more paranoid about
750checking the FAT superblock values.
751
Theodore Ts'o34a26112006-03-29 20:40:23 -0500752Fixed a fd leak in the uuid library which was causing problems for the
753LVM tools. (Addresses Debian Bug: #345832)
754
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500755Add support for the reiser4 and software suspend partitions to the
756blkid library. Also add support for extract the label from iso9660
757filesystems.
758
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400759Fix a compile_et bug which miscount the number of error messages if
760continuations are used in the .et file.
761
762Add extra sanity checks to protect users from unusual cirucmstances
763where /etc/mtab may not be sane, by checking to see if the device is
764reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
765#319002)
766

771e2fsck context structure.
772

784Programmer's notes:
785-------------------
786
Theodore Ts'o7e2ec012006-04-22 04:29:16 -0400787Update config.guess and config.sub to latest version (2006-02-23) from
788FSF.
789
790Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
791Bugs: #360661, #360317)
792
Theodore Ts'o34a26112006-03-29 20:40:23 -0500793Fixed the Makefile so that they work correctly on newer versions of
794GNU make (i.e., 3.81).
795
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400796Add valgrind support to the regression test suites, and eliminate
797false positives from valgrind.
798
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500799Add a regression test suite for the blkid library.
800
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400801Fix a fencepost error in resize2fs caught by valgrind.
802
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500803Fix compiler warnings about missing memcpy prototypes.
804
805We no longer have the sparc assembly code in the header file any more,
806so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
807break compiles on the sparc architectures when using gcc.
808
809In the libext2fs library, add the new field fs->now which if non-zero
810is used instead of the system time when setting various filesystem
811fields (last modified time, last write time, etc.)
812
813Fix gcc 4.01 complaints by adding a missing #include <string.h> to
814ext2fs.h which is needed since the inline functions use memcpy().
815(Addresses Sourceforge Bug #1251062)
816
817Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
818the build system when building files in the util directory which are
819needed during the build process. This avoids potential problems when
820cross-compiling and some of the options specified in CFLAGS or LDFLAGS
821are not recognized as valid by the host compiler. (Addresses
822Sourceforge Bug #1261547)

824Clean up the blkid library by making the superblock and generic i/o
825functions to be more generic. Clean up interface to the probe
826function, and fix memory leak. Finallly, remove an unneeded reference
827to probe.h in the lib/blkid/resolve.c
828
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500829Add an ext2fs_read_bb_FILE regression test to confirm proper detection
830of invalid block #'s.
831
Theodore Ts'o34a26112006-03-29 20:40:23 -0500832The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
833indicate that the the function read/writes the memory location.
834
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500835Fix various gcc -Wall complaints.
836
837Add a dependency to make sure that the subdirectories are created
838before creating all of the object files, in order to address parallel
839build problem in the library Makefiles. (Addresses Sourceforge Bug:
840#1261553)
841
842Add $(LDFLAGS) to the command line argument when generating an ELF or
843Solaris shared library, to allow cross-compile and other builds that
844might need to specify -L paths to needed libraries. (Addresses
845Sourceforge Bug #1261549)
846
Theodore Ts'obae55642006-05-14 17:31:48 -0400847Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
848intended for testing purposes. It allows an ext2/ext3 developer to
849create very large filesystems using sparse files where most of the
850block groups are not initialized and so do not require much disk
851space. Eventually it could be used as a way of speeding up mke2fs and
852e2fsck for large filesystem, but that would be best done by adding an
853RO_COMPAT extension to the filesystem to allow the inode table to be
854lazily initialized on a per-block basis, instead of being entirely
855initialized or entirely unused on a per-blockgroup basis.
856
Theodore Ts'o6c094752006-05-29 11:47:25 -0400857Fix backwards compatibility so e2fsprogs will better compile on Linux
8582.0.35 systems.
859
860Make test scripts more robust against locale-related environment variables
861
862Fix type warning problem with sizeof() in ext2fs_open2().
863
864Fix type warning problem with time_t in debugfs.

Theodore Ts'ofea95ff2005-07-01 17:31:55 -0500867E2fsprogs 1.38 (June 30, 2005)
Theodore Ts'o1f965c82005-06-30 20:06:45 -0400868==============================
869
870Fix blkid's test programs (built with "make check") compile correctly
871even without "configure --enable-blkid-debug".
872
873Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
874type aliasing rules on newer gcc compilers. (Addresses Red Hat
875Bugzilla ##161183.)
876
877Fix com_err library to make it more compatible with recent changes
878made to the com_err library in MIT Kerberos V5 version 1.4.
879(Addresses Sourcefroge Bug #1150146)
880
881General cleanup of messages printed by e2fsprogs programs for grammar,
882consistency, and to make life easier for translators. Fixed a few
883strings containing English that had not been marked as needing
884translations. Removed strings that do not need to be translated, to
885make life easier for translators.
886
887Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
888test to see if a device appears to be in use instead of just relying
889on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
890
891Fix portability problem in the filefrag program affecting platforms
892where the size of an integer is smaller than the size of a long.
893(Addresses Debian Bug #309655)
894
895Mke2fs will now use a larger journal by default for filesystems
896greater than 4GB. (128 MB instead of 32MB).
897
898Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
899unless forced. This is to avoid signed vs. unsigned kernel bugs in
900block numbers that still need to be fixed.
901
902The blkid program has a new option which will more efficiently search
903for device when it is known (or expected) that only one matching
904device will be found in the system, such as when doing a lookup by
905UUID.
906
907Debian's e2fsprogs-specific initrd fragment will avoid including
908unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
909and LD_LIBRARY_PATH, and filtering out libraries found in
910/etc/ld.so.preload. (Addresses Debian Bug: #304003)
911
912Fixed a potential portability issue in the blkid programs for
913architectures where the char type is unsigned. (Addresses Sourceforge
914Bug: #1180585)
915
916Fix a bug in filefrag so that it doesn't falsely count an extra
917discontinuity when the first block found is an indirect block.
918(Addresses Debian Bug #307607).
919
920Fix blkid's recognition of cramfs filesystems, and enhance it to be
921able to handle cramfs labels.
922
923Fix debugfs's stat command to not core dump when a filesystem is not
924open.
925
926Fix e2fsck's handling of error conditions caused by the resize inode
927claiming blocks that are also used by other inodes, a filesystem
928corruption which was commonly caused by a bug in Fedora Core 3's
929resize2fs program.
930
931Fixed bug in filefrag which caused it to fail on non-ext2/3
932filesystems. (Addresses Debian Bug: #303509)
933
934If the superblock last mount time indicates that the system clock may
935not be accurate, then e2fsck will omit checking inodes' deletion time
936field for indications of a potential corrupted orphaned inode list.
937(Previously e2fsck only ommited these LOW_DTIME checks when the
938superblock's last write time looked insane.)
939
940Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
941(Addresses Debian bug #302200)
942
943Make the blkid library more paranoid about being run from setgid
944programs, and to use __secure_getenv() from libc if it is available.
945
946Fixed spelling mistakes, typos, and otherwise clarified man pages.
947(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
948and Sourceforge Bug: #1189803)
949
950Updated and fixed translations.
951
952Fixed various Debian packaging issues --- see debian/changelog for
953details.
954
955Programmer's notes:
956-------------------
957
958Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
959changed to take an unsigned int for the bit number. Negative bit
960numbers were never allowed (and didn't make any sense), so this should
961be a safe change. This is needed to allow safe use of block numbers
962greater than or equal to 2**31.
963
964The compile_et program will avoid recreating generated foo_err.c and
965foo_err.h files if no changes are necessary. The compile_et program
966will also atomically replace these files to avoid a potential parallel
967build race problem on SMP systems. (Addresses Sourceforge Bug:
968#1157933)
969
970Added a new function to the blkid library, blkid_probe_all_new(),
971which only probes newly added disk devices, and change
972blkid_find_dev_with_tag() to use this function so that when a
973requested tag is not found, devices that were previously not checked
974are searched before searching all devices in the system.
975
976Added new functions to the blkid library, blkid_dev_set_search() and
977blkid_dev_has_tag().
978
979E2fsck's problem strings can now use @m and @n as abbrevations for
980"multiply-claimed" and "invalid", respectively.
981
982The e2fsprog.pot file now has an explanation of how the @-expansion
983and %-expansion works, and strings in e2fsck/problem.c which contain @
984characters now have comments in e2fsprogs.pot with the @-expansion to
985make life easier for translators.
986
987Fixed missing return values in the ext2fs library which could cause it
988to return random garbage in certain error conditions.
989
990Allow the current time to be overriden via the E2FSCK_TIME environment
991variable for use in regression tests.
992
993The test scrpit driver program now exits with a non-zero status if
994there any of its test that it ran failed.
995
996Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
997Bug: #1157933)
998
999Fixed "make check" so that it compiles correctly even when e2fsprogs'
1000header files have not be installed in the system include directories.
1001(Addresses Sourceforge Bug: #1180572)
1002
1003Fixed gcc -Wall nits.
1004
1005
Theodore Ts'ofd4b28e2005-03-21 22:37:03 -05001006E2fsprogs 1.37 (March 21, 2005)
1007===============================
1008
1009Add support for checking the validity of Extended Attributes stored in
1010inodes to e2fsck.
1011
1012Add support for dumping the contents of large inodes to debugfs,
1013including the extended attributes stored in inodes.
1014
1015Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1016when we create a new inode we make sure that the extra information in
1017the inode (any extra fields in a large inode and any ea-in-inode
1018information) is initialized correctly. This can take place when
1019mke2fs creates the root and lost+found directory, when e2fsck creates
1020a new root inode or a new lost+found directory, and when the user uses
1021the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1022create inode could inherit garbage (or old EA information) from a
1023previously deleted inode.
1024
1025Fixed a bug in e2fsck so it would notice if a file with an extended
1026attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1027to zero.
1028
1029Added support to filefrag to detect files which are using the new
1030experimental file extents format, and use the non-ext2 algorithm in
1031that case. Fixed a bug to avoid reporting a false discontinuity if
1032there is one or more unallocated blocks at the beginning of a file.
1033
1034Duplicated a check for noticing whether or not the number of blocks
1035(given a certain blocksize) is greater than 2**32 when the
1036BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1037allows mke2fs to automatically use a larger blocksize when creating a
1038filesystem on a very large device when run on systems that do not
1039support BLKGETSIZE64.
1040
1041Fix the I18N build which was broken in e2fsprogs 1.36 because the
1042build system had been switched to treat the .gmo files as shipped
1043files (for backwards compatibility with systems that have older GNU
1044I18N tools installed), but the gen_tarball.in script was still
1045removing the .gmo files from the official source distribution.
1046
1047Fixed various Debian packaging issues --- see debian/changelog for
1048details. (Addresses Debian Bugs ##296769, #299341)
1049
1050Programmer's notes:
1051-------------------
1052
1053Added new functions to the e2p library which convert between a string
1054and os_type: e2p_os2string() and e2p_string2os(), and used them to
1055make the generated binaries more compact.
1056
1057Fixed a compile-time error on Darwin systems.
1058
1059Cleaned up the lib/ext2fs Makefile slightly.
1060
1061
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001062E2fsprogs 1.36 (February 4, 2005)
1063=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001064
1065All of the patches that were applied to Fedore Core 3's
1066e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1067lot of bug fixes first. Users of Fedora Core 3 are strongly
1068encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1069
1070Add support for filesystem with the online resizing via resize inode
1071feature. Fixed numerous bugs from the Fedora patches. The Fedora
1072patches also didn't bother to do any consistency checking on the
1073resize inode, or add any tests to the regression test suite. The "-R
1074resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1075being listed in mke2fs's usage message. All of these shortcomings
1076have been corrected.
1077
1078E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1079program. In order to do this, the user must run the commands:
1080
Theodore Ts'od0a3b462005-05-05 22:57:44 -04001081 debugfs -w /dev/hdXXX -R "features ^resize_inode"
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001082 e2fsck -f /dev/hdXXX
1083
1084Optionally, the ext2prepare command can be used to re-enable online
1085resizing after the filesystem has been fixed.
1086
1087The fsck program will now accept an optional filedescriptor argument
1088to the -C option. (The Fedora version of this patch would sometimes
1089cause fsck to ignore a parameter on fsck's command line in some rare
1090cases, sigh.)
1091
Theodore Ts'odc256972005-01-26 13:20:12 -05001092Make sure e2fsprogs doesn't write garbage into the reserved portion of
1093large inodes.
1094
1095Make sure resize2fs releases the blocks belonging to the old inode
1096table blocks when moving the inode table. (Addresses Debian Bug:
1097#290894)
1098
1099Skip the r_resize_inode test if resize2fs is not compiled (due to
1100configure --disable-resizer)
1101
1102E2fsck now checks the summary filesystem accounting information, and
1103if any of the information is obviously wrong, it will force a full
1104filesystem check. (Addresses Debian Bug #291571)
1105
1106Fix e2fsck to not complain when the resize_inode feature is enabled,
1107s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1108the resize inode.
1109
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001110Fix e2fsck to note delete symlinks that contain an extended attribute
1111after the ext_attr feature flag has been cleared. (Addresses Red Hat
1112Bugzilla #146284).
1113
Theodore Ts'odc256972005-01-26 13:20:12 -05001114Add new utility program, copy_sparse.c, which is very useful
1115for dealing with large sparse files (such as e2image files).
1116
1117Add support for jnl_blocks[] for debugfs's set_super_value.
1118
1119Fix filefrag so that it works correctly with sparse files.
1120
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001121Filefrag -v will print first and last blocks.
1122
Theodore Ts'odc256972005-01-26 13:20:12 -05001123Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1124and dumpe2fs.
1125
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001126Add mke2fs support so that it can support filesystems larger than 4TB
1127automatically, by retrying with a 4k blocksize if the device size is
1128too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1129bug #1106631)
1130
Theodore Ts'odc256972005-01-26 13:20:12 -05001131Change blkid to test for NTFS first because Windows sometimes doesn't
1132clear enough of the parition to confuse the probing routines into
1133thinking the old filesystem type is still valid. (Addresses Debian
1134Bug #291990)
1135
Theodore Ts'o66fa0de2005-01-11 14:39:55 -05001136Add support for swap partition label and uuid's in the blkid library.
1137
Theodore Ts'odc256972005-01-26 13:20:12 -05001138Add support to the blkid library to recognize Oracle ASM volumes.
1139
1140Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001141not just the first one, and work more consistently when the blkid
1142cache file is not available or set to /dev/null. (Addresses Debian
1143Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -05001144
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001145Badblocks will now correctly display block numbers greater than
1146999,999,999 in its progress display.
1147
1148The tune2fs program will not allow the user from setting a ridiculous
1149number of reserved blocks which would cause e2fsck to assume the
1150superblock was corrupt. E2fsck's standards for what is a ridiculous
1151number of reserved block has also been relaxed to 50% of the blocks in
1152the filesystem.
1153
1154The blkid library will return vfat in preference to msdos, and ext3 in
1155preference to ext2 (if the journalling flag is set) so that mount will
1156do the right thing. (Addresses Debian bug #287455)
1157
1158Mke2fs will now use the -E option for extended options; the old -R
1159(raid options) option is still accepted for backwards compatibility.
1160Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1161
1162Mke2fs will now accept a size in megabytes, gigabytes, and other units
1163(via "32m" or "4g" on the command line) if the user finds this more
1164convenient than specifying a block count.
1165
1166Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1167cache conherency problem.
1168
1169Debugfs now supports a new command, set_inode_field, which allows a
1170user to manually set a specific inode field more conveniently, as well
1171as set entries in the indirect block map.
1172
1173Debugfs's set_super_value command has been enhanced so that the user
1174can set most superblock fields, including the date/time fields and
1175some of the more newsly added superblock fields.
1176
1177E2fsprogs programs now accept an offset to be passed to the file
1178specifiers, via the syntax: "/tmp/test.img?offset=1024".
1179
1180E2fsprogs programs will now accept blocksizes up to 65536; kernel
1181support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001182other architectures with page sizes greater than 4k. There are 2.6
1183kernel patches out there which enable this, but they are of this
1184writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001185
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05001186The e2image command now takes the -s option which will scramble
1187directory entries for raw image files.
1188
1189Fix a file descriptor leak in the filefrag program.
1190
1191Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1192present.
1193
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001194Fix bug in debugfs where kill_file would lead to errors when deleting
1195devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1196
1197Fix bug in the blkid library when detecting the ocfs1 filesystem
1198
1199Remove obsolete EVMS 1.x and a.out DLL support.
1200
1201E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -04001202
1203Fixed two potential ordering constraint problems in e2fsck which might
1204cause the filesystem to be corrupted if e2fsck is interrupted during a
1205(extremely narrow) race window. Thanks to Junfeng Yang from the
1206Stanford Metacompilation group for pointing this out.
1207
1208Fixed bug in e2fsck where it would not accurately detect whether or
1209not the system is running on adaptor if the ACPI device representing
1210the AC adapter didn't correspond to the what was used on IBM
1211Thinkpads.
1212
1213Change e2fsck to accept directories greater than 32MB.
1214
1215Fix e2fsck so that a checkinterval of zero disables a time-based check
1216of the filesystem.
1217
1218Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
1219to the PAGER environment variable. (Addresses Debian Bug #239547)
1220
1221Tune2fs will not mark rewrite the superblock if the feature bitmasks
1222are not modified.
1223
1224The debugfs program will set the filetype information when creating a
1225link.
1226
1227Add debugfs -d option to use a separate source of data blocks when
1228reading from an e2image file.
1229
1230Add e2image -I option which allows the e2image metadata to be
1231installed into a filesystem.
1232
1233Fixed bug in the badblocks program which caused "done" to always
1234appear in english even when a translation was available. (Addresses
1235Debian Bug #252836)
1236
1237The blkid program has a new option -o which controls the output format
1238of the blkid program; this is makes blkid more convenient to use in
1239shell scripts.
1240
1241Fix a minor bug in uuid library, which was not using the full 14 bits
1242of clock sequence when generating UUID's.
1243
1244Fix a Y8.8888K problem in the uuid library.
1245
1246Logsave now creates a new session id for itself to avoid getting
1247killed by init whan transitioning between init levels.
1248
1249Change the licensing of the UUID library to be the 3-clause BSD-style
1250license; this allows Apple to use the uuid library in Darwin.
1251
1252Add ocfs and ocfs2 probe support into the blkid library.
1253
1254Fix a memory and file descriptor leak in the blkid library.
1255
1256The blkid library will revalidate the device if the system time is
1257earlier than last verification time of the device, since that
1258indicates that the system time is probably nottrustworthy.

1260The blkid library will override the default location of the blkid.tab
1261file by the BLKID_FILE environment variable, if it is available.
1262
1263Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
1264
1265Add various portability fixes for lame new versions of glibc, Darwin
1266and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian

1284Programmer's notes:
1285-------------------
1286
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001287Fixed various gcc -Wall warnings.
Theodore Ts'o48301122004-09-19 08:23:41 -04001288
1289The uuid library now has new functions uuid_unparse_upper() and
1290uuid_unparse_lower() which forces the case of the hex digits to be
1291upper case, or lower case.
1292
1293The build process has been speeded up by enhancing the subst program
1294to update the modtime on the generated files even when the generated
1295file hasn't changed.
1296
1297The uuid library now uses C99 stdint.h types instead of custom types.
1298
1299Updated config.guess and config.sub with newer versions from the FSF.
1300
1301Removed out of date .cvsignore files from the source distribution.
1302
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001303The ext2fs_unlink() function will return an error if both the name and
1304inode number are unspecified, to avoid doing something surprising
1305(such as unconditionally deleting the first directory entry).
1306Directory entries are now deleted by coalescing them with the previous
1307directory entry if possible, to avoid directory fragmentation. This
1308is not an issue with the e2fsprogs suite, but may be a problem for
1309some of the users of libext2fs, such as e2tools.
1310
1311Add support for version numbers of the form "1.36-rc1".
1312
Theodore Ts'o48301122004-09-19 08:23:41 -04001313Fix build of mke2fs.static.
1314
Theodore Ts'odc256972005-01-26 13:20:12 -05001315Add basic ext2fs library support for large (EA in inode) inodes.
1316
Theodore Ts'o48301122004-09-19 08:23:41 -04001317The test_io mechanism can now abort after n reads or writes to a
1318particular block. The block is specified by TEST_IO_BLOCK environment
1319variable, and the read/write count by the TEST_IO_READ_ABORT and
1320TEST_IO_WRITE_ABORT environment variables. The block data is now only
1321dumped if the 0x10 bit is set in TEST_IO_FLAGS.
1322
1323UUID_DEFINE() in the uuid library now creates a static variable, with
1324__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
1325be used in header files.
1326
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001327Add support for the install-strip and install-shlibs-strip targets, as
1328suggested by the GNU coding guielines. "make install" no longer
1329strips the binaries which are installed.
1330
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001331Remove support for the --enable-old-bitops configure option which was
1332only for very old sparc systems.
1333
1334Remove support for --enable-clear-htree; this was only needed during
1335the early development of the htree patch.
1336
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05001337Use Linux-kernel-style makefile output so it is easier to see compiler
1338warnings.
1339
1340Update gettext files to version 0.14.1.
1341
1342Update to use autoconf 2.5x.
1343
1344Improved support for compiling e2fsprogs under dietlibc.
1345
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05001346Make e2fsprogs portable to Solaris and FreeBSD systems.
1347
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05001348Add blkid_verify(), blkid_get_library_version(), and
1349blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -05001350
1351Add pkg-config files for e2fsprogs's libraries.
1352
1353Fix "make uninstall" to so that it removes everything that is installed.
1354
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05001355Add a configure --enable-maintainer-mode option which enables the
1356makefile rules to rebuild the configure script from configure.in, and
1357to reubuild the .gmo files in po directory.
1358
1359Drop the sparc assembly bitwise operations; it's less efficient
1360than the GCC 3.4 compile code and triggers compiler warnings on
1361sparc64. Thanks to Matthias Andree for his analysis and suggestions.

Theodore Ts'ob70b1162004-02-28 10:52:35 -05001365E2fsprogs 1.35 (February 28, 2004)
1366==================================
1367
Theodore Ts'o48301122004-09-19 08:23:41 -04001368E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001369preserves the existing badblocks list.
1370
Theodore Ts'o48301122004-09-19 08:23:41 -04001371Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001372
1373E2fsprogs will now deal correctly with symlinks that contain
1374extended attribute information, which can be created using SE Linux.
1375(Addresses Debian Bug #232328)
1376
1377Remove a double longjump into an invalid stack frame bug in e2fsck.
1378(This was during an abort sequence, which normally worked on Linux and
1379caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001380
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001381Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
1382(the NLS library will replace "" with the .po header information).
1383
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001384Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
1385dump due to a division by zero error. (Addresses Debian bug #207082)
1386
Theodore Ts'o151a7162003-12-26 14:04:33 -05001387Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
1388when reconnecting a directory requires creating a lost+found
1389directory. (Addresses Debian bug #219640).
1390
1391Fixed a bug where e2fsck would bomb out if a journal needed to be
1392replayed when using an alternate superblock.
1393
Theodore Ts'o48301122004-09-19 08:23:41 -04001394E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001395if the laptop is running on battery. The next time fsck runs while
1396the system is on the AC mains, or after the grace period is exceeded,
1397the filesystem will be checked. (Addresses Debian bug #205177)
1398
1399E2fsck will inform the user when there are 5 or fewer mounts before a
1400filesystem check will be forced. (Addresses Debian bug #157194)
1401
1402Fix e2fsck's handling of corrupted indirect blocks in the bad block.
1403We now correctly handle the case where there is an overlap between a
1404block group descriptor or a superblock and a bad block indirect block.
1405In the case where the indirect block is corrupted, we now suggest
1406"e2fsck -c".
1407
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001408Fix byte swap bugs in e2fsck that caused the journal backup location
1409in the superblock and symlinks created by SE Linux to be cleared
1410by e2fsck on big-endian machines. (Addresses Debian bug #228723)
1411
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001412E2fsck -c now replaces the current list of bad blocks with the ones
1413found by badblocks.
1414
1415Fix bugs in e2fsck and tune2fs which could cause a core dump if a
1416non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
1417
1418Fix a potential bug in e2fsck which could cause it to core dump when
1419trying to print the location of the backup superblock.
1420
1421Protect against a potential core dump in e2fsck when printing a
1422message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001423
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001424Add support for backing up the journal inode location in the
1425superblock. E2fsck will automatically save the journal information in
1426the superblock if it is not there already, and will use it if the
1427journal inode appears to be corrupted. ext2fs_add_journal_inode()
1428will also save the backup information, so that new filesystems created
1429by mke2fs and filesystems that have journals added via tune2fs will
1430also have journal location written to the superblock as well.
1431Debugfs's logdump command has been enhanced so that it can use the
1432journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001433
1434E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001435
1436Shrink the size of the e2fsck executable by moving some initialized
1437variables to the BSS segment.
1438
1439E2fsck will avoid printing the ^A and ^B characters which bracket the
1440progress bar when stdout and stdin are a tty device instead of a pipe
1441to another program. (Addresses Debian bug #204137)
1442
Theodore Ts'o151a7162003-12-26 14:04:33 -05001443Debugfs's mkdir command will automatically expand the directory if
1444necessary. (Addresses Debian Bug: #217892)
1445
1446Fixed a bug in debugfs so that copying a file from /dev/null uses the
1447correct mode bits. (Addresses Debian Bug: #217456)
1448
1449If the environment variables DEBUFS_PAGER and PAGER are not set,
1450debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -05001451/usr/bin/pager, and then falling back to 'more' and 'less'.
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001452(Addresses Debian bug #221977)
1453
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001454Debugfs will now support 2.6 device numbers where the major or minor
1455number may be larger than 255. (Addresses Sourceforge bug #865289)
1456
Theodore Ts'o48301122004-09-19 08:23:41 -04001457Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
1458
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001459Chattr now stops processing options when it sees '--'. (Addresses
1460Debian bug #225188)
Theodore Ts'o151a7162003-12-26 14:04:33 -05001461
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001462Fix regression tests so they work correctly when e2fsprogs is compiled
1463with configure --disable-htree.
1464
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001465Fix bug in uuid library when there is no network card and the library
1466is generating a time-based uuid. The random MAC address was not
1467correctly generated to be a multicast address.
1468
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001469Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -04001470around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001471
1472Fix bug in badblocks when using O_DIRECT; we need to make sure that
1473we're reading from an offset which is page aligned. For read-only and
1474read-write tests, we try to recover after an error so that we can
1475continue reading on page-aligned boundaries. (Addresses Debian Bug

1488Programmer's notes:
1489-------------------
1490
Theodore Ts'ob70b1162004-02-28 10:52:35 -05001491Fixed a build problem so that e2fsprogs would compile with the
1492--enable-profile option to configure selected. (Addresses Sourceforge
1493bug #811408)
1494
1495Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
1496Bugzilla Bug #112448)
1497
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001498Centralize code which calculates the location of the superblock
1499and block group descriptors so that it is in a single library routine.
1500
Theodore Ts'o6826bde2003-08-21 02:14:44 -04001501Added two new functions, ext2fs_file_open2() and
1502ext2fs_inode_io_intern2() which take a pointer to an inode structure.
1503
1504Fix compile_et to output the correct prototype for
1505initialize_xxx_err_table_r() in the header file. (Addresses Debian
1506bug #204332)
1507
1508In the lib/et makefile, make sure com_err.info is deleted on "make clean".
1509
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001510Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
1511present. This is for when we try stuffing an int into void * pointer.
1512
1513Fix type-punning which can cause gcc 3.x to miscompile code by getting
1514confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
1515and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
1516**'. The EVMS code uses an ugly union approach since we don't want to
1517modify the EVMS interfaces.
1518
1519Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
1520aid build process on systems can use invoke GNU make as "gmake".
1521
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001522Added regression testing for mke2fs.

1525
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001526Fixed various compiler warnings.

Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001532E2fsprogs 1.34 (July 25, 2003)
1533===============================
1534
1535Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
1536a tight loop while waiting for a child fsck to exit in some cases.
1537This burns CPU times which slows down the low-level filesystem check.
1538
1539Added code to mke2fs to assure that the default block size for a
1540filesystem is at least as big as the sector size of the device, if it
1541can be determined.
1542
1543Changed mke2fs and resize2fs to round the default size of a filesystem
1544to be an even multiple of the VM pagesize in order to avoid a Linux
1545kernel bug introduced when the storage of the buffer cache was moved
1546into the page cache.
1547
1548Mke2fs will warn the user when creating a filesystem with journaling
1549and a blocksize greater than 4096. (Addresses Debian bug #193773)
1550
1551Fixed a bug in resize2fs which caused it to fail on filesystems with a
1552non-empty bad block list. Resize2fs now discards any blocks on the
1553badblock list which are no longer part of the filesystem as the result
1554of a filesystem shrink. (Note: this means that shrinking and then
1555enlarging a filesystem is no longer a reversible operation;
1556information about bad blocks in the part of the filesystem which is to
1557be chopped off will be lost.)
1558
1559Changed resize2fs so the user can use prefixes to specify the units of
1560the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
1561and to make the error and informational messages explicitly display
1562the blocksize used by the filesystem, in order to avoid confusion.
1563(Addresses Debian bug: #189814)
1564
1565Added a new debugfs command, dump_unused, which dumps the contents of
1566all unused blocks to stdout. (Useful as an emergency try-to-find
1567deleted data command.)
1568
1569Added a new debugfs command, imap, which prints the location of a
1570specified inode in the inode table.
1571
1572Fixed a bug in the badblocks program which caused it to use one bit of
1573randomness in its non-destructive read/write test, instead of using a
1574full 8 bits of randomness.
1575
1576Added a new option (-t) to badblocks, which allows the user to control
1577the test pattern(s) used when checking a disk.
1578
1579The blkid probe function now more correctly detects UDF filesystems.
1580
1581Fixed a bug in the blkid library which caused it to not update its
1582cache if a filesystem changes from having a label to not having a
1583label.
1584
1585Fixed a bug in the blkid library wihch could avoid an infinite loop
1586in blkid_find_dev_with_tag() if /proc is not mounted and there the
1587/etc/blkid.tab file has not yet been created.
1588
1589Fixed the badblocks program so that the destructive read/write test
1590honors the -c option, and to use O_DIRECT when possible to avoid
1591thrashing the system block buffer cache.
1592
1593Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -04001594 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001595 - Removed testing NYC translation
1596 - Fixed NLS support for message abbrevations in e2fsck
1597 - Remove de-utf.po, since we shouldn't have two versions using different
1598 charset encodings.
1599 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
1600 simplify the statistics reporting in e2fsck.
1601
1602Changed configure.in so that its defaults for *BSD systems no longer
1603build an fsck wrapper, and not to install in /usr/local by default.
1604
1605Fixed some minor spelling errors/typo's in e2fsck and the configure
1606script.
1607
1608Fixed various Debian packaging issues (see debian/changelog).
1609
1610Updated and clarified man pages. (Addresses Debian Bug #195616)
1611
1612Programmer's notes:
1613-------------------
1614
1615Fix gcc -Wall nitpicks.
1616
1617Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
1618NLS support by default. (Added partial workaround for gettext/Darwin
1619incompatibility problems.)
1620
1621Added full MIT KRB5 and Himdall compaibility support to the com_err
1622library and the compile_et program. (Addresses Debian bug #191900)
1623
1624Added the blkid_known_fstype() function to the blkid library, which
1625returns true if it is passed a filesystem type which is recognized by
1626the blkid probing functions.
1627
1628Improved the documentation for the blkid library.
1629
1630Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
1631returns the hardware sector size of a device, if it is available.
1632
1633Added a dependency in the blkid library's .so file to the uuid
1634library, since the former uses the latter. (Addresses Debian bug
1635#194094)
1636
1637Added --with-diet-libc and --disable-evms to the configure script.
1638
1639Fixed a minor memory leak in the badblocks program.
1640
1641Fixed a portability problem in tune2fs --- not all systems have strptime().
1642
1643Fixed a portability problem in debugfs with the use of getopt() more
1644than once. Old-style BSD, new-style BSD, and Linux C libraries all do
1645things differently.
1646
1647Add support Windows support to ext2fs_get_device_size().
1648
1649Added (normally disabled) debugging code to the Unix I/O manager which
1650causes it to disable all userspace caching if the NO_IO_CACHE is
1651defined.
1652
1653Changed the test I/O manager so it can always be linked into e2fsck,
1654mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
1655configure script. The test I/O manager will only print any debugging
1656information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
1657variables are set, which specifies which I/O operations are logged and
1658a block number to watch, respectively. The log messages are sent to
1659stderr by default, unless a filename is specified via the
1660TEST_IO_LOGFILE environment variable.

Theodore Ts'o71df0dc2003-04-21 16:17:09 -04001663E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001664===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001665
Theodore Ts'oba142c12003-04-16 00:59:59 -04001666Added a new utility program, logsave, which captures the output of a
1667command in a log file, even if the containing directory hasn't been
1668mounted yet (in which case the it saves the output in memory until it
1669can write out the logfile). This is useful for capturing the
1670output of fsck during the boot sequence.
1671
1672Fixed some portability problems that were causing problems under
1673the Cygwin32 environment.
1674
1675Mke2fs now interprets a negative number to the -b option as a minimum
1676block size.
1677
1678Fixed a bug in mke2fs which was incorrectly checking the argument to
1679the -g option if the default block size was used. (Addresses Debian
1680bug #188319)
1681
1682Fsck now explicitly ignores tmpfs and devpts, and it will complain if
1683it can not find filesystem checkers for jfs, reseirfs, and xfs.
1684
1685E2fsck now updates the global free block and inode counters from the
1686block group specific counters quietly. This is needed for an
1687experimental patch which eliminates locking the entire filesystem when
1688allocating blocks or inodes; if the filesystem is not unmounted
1689cleanly, the global counts may not be accurate.
1690
1691Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
16922.0 is not yet supported; this only pulled in the bug fixes: fixed
1693possible hangs caused by bugs in calling waitpid, and not setting the
1694pipe to non-blocking mode; also fixed a file descriptor leak; made
1695sure all functions call log entry/exit functions.)
1696
1697Badblocks now flushes its output file as bad blocks are discovered.
1698
1699The uuid library is now more paranoid about assuming the correctness
1700of the /dev/random device; it mixes in a stream of bytes from
1701random/srandom, just in case.
1702
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001703Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04001704maintainer of e2fsprogs. Other various Debian-specific packaging
1705cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001706
1707Move the source tarball generation functions from the top-level
1708makefile to the util/gen-tarball script.
1709
1710Updated the Turkish .po translation file.
1711
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001712Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001713it more compatible with com_err libraries from those distributions.
1714
1715Changed dumpe2fs to always display the superblock fields relating to
1716the journalling and/or directory indexing feature even if those
1717features are not enabled.
1718
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001719Updated and clarify copyright statement vis-a-vis alpha releases of
1720e2fsprogs.
1721
1722The ss library will now try to dynamically link to the readline
1723library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04001724the debugfs program now has line editing and history features. The
1725SS_READLINE_PATH environment variable is used to find a readline or
1726readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001727
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001728E2fsck now finds most duplicate filenames (all when rebuilding all
1729directories via the -D option) and offers to delete or rename
1730duplicate filenames/directory entries. (Addresses Debian Bug #176814).
1731
1732Fix bug in e2image. When writing out a raw image file, include data
1733blocks from symlinks that do not store the symlink within the inode.
1734
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001735Fix bug in resize2fs which incorrectly moved the block and inode
1736bitmaps for sparse superblock filesystems and incorrectly marked
1737blocks as in use. (Addresses Debian bug #174766)
1738
1739Added a new shared library, the blkid library, which efficiently
1740allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
1741and UUID filesystem specifiers without needing to search all of the
1742devices in the system. Instead, the device is looked up in a cache
1743file, and then verified to make sure the blkid cache is correct.
1744
1745Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
1746the device name, using the blkid library. (Addresses Debian bugs
1747#166048, #179671)
1748
1749Fsck now supports backslash escapes in /etc/fstab so that \040 can be
1750used for spaces in device labels.
1751
1752Removed 32-bit limitations for debugfs's dump command.
1753
1754If the user specifies a large number of inodes, Mke2fs will
1755automatically adjust the number of blocks per group to find a valid
1756set of filesystem parameters.
1757
1758Add workaround to detect broken MD devices where when some of the
1759underlying devices are marked read-only, writes to the MD device are
1760silently dropped. E2fsck will detect if there is an attempt to run
1761the journal twice, and abort with an error if this is the case.
1762(Addresses IBM Bugzilla bug #1226)
1763
1764E2fsck will print an error if more than one of the -p/-a, -n or -y
1765options are specified.
1766
1767E2fsck will fix HTREE corruptions in preen mode, without stopping the
1768boot process. This is needed because the 2.4 ext2 filesystem
1769accidentally had the INDEX_FL backwards compatibility code removed.
1770
1771Mke2fs no longer creates filesystems with the dir_index flag set by
1772default; the user has to specifically request it.
1773
1774Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04001775#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001776
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001777Created man page for the mk_cmds program (from the libss library).
1778
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001779Programmer's notes:
1780-------------------
1781
1782Fix various gcc -Wall nits.
1783
1784Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001785successfully under Solaris and Apple/Darwin.
1786
1787Fixed a Makefile dependency to allow building e2fsprogs using parallel
1788make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001789
1790Changes to create a subset distribution which consists only of the
1791et, ss, uuid, and blkid libraries. The configure script and top-level
1792makefile were changed to support working with a subset distribution.
1793
Theodore Ts'oba142c12003-04-16 00:59:59 -04001794Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
1795actually used, and might people who are looking for
1796EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
1797
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001798Updated debian files to fix a number of Lintian warnings.
1799
1800Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001801
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04001802Removed unnecessary libraries from being linked into the fsck, lsattr,
1803chattr, and blkid executables.
1804
Theodore Ts'o38513012002-11-09 15:00:56 -05001805E2fsprogs 1.32 (Nomvember 9, 2002)
1806==================================
1807
1808Fixed a bug in the Unix I/O routines which caused needless writebacks
1809of clean blocks from the unix_io cache (they were erroneously marked
1810as being dirty, so they were getting written back to disk before
1811getting evicted from the disk cache). This was harmless, but it
1812significantly slowed down e2fsck.
1813
1814Made some other minor optimizations to the Unix I/O routines to save a
1815small amount of CPU time.
1816
1817Updated internationalization files.
1818
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001819
Theodore Ts'oae65b292002-11-08 20:08:48 -05001820E2fsprogs 1.31 (Nomvember 8, 2002)
1821==================================
1822
1823Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
1824compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
1825handling for child process that die unexpectly. Add a hack to force
1826mkfs to create filesystems that won't cause problems with hardware
1827that has 2k or 4k minimum blocksize requirements. Read from child
1828processes in non-blocking mode, so that the GUI continues to update.
1829
1830Fix e2fsck so that it returns the appropriate exit code when the root
1831filesystem has been changed, so that system's rc scripts will be told that
1832the system needs to be rebooted.
1833
1834Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
1835was set, some of the descriptor blocks that should have been written
1836out were getting skipped.
1837
1838Changed e2fsck to force out changes to the backup copies of the
1839superblock and block group descriptors when important changes are made
1840to those data structures.
1841
1842Fix a bug where e2fsck could erroneously mark a filesystem as being
1843clean if a check of dirty filesystem is interrupted with a ^C. (Bug
1844introduced in e2fsprogs 1.28.)
1845
1846If journal debuging is enabled using --enable-jbd-debug, the debugging
1847level is now set via the E2FSCK_JBD_DEBUG environment variable.
1848
1849If byteswapping support is disabled using configure --disable-swapfs,
1850skip the tests which depend on byte-swapping, so that "make check"
1851won't bomb out.
1852
1853Lshattr will now display the indexed directory flag. Also, some of
1854the more esoteric compression flags are supressed unless compression
1855support has been enabled.
1856
1857Update man pages.
1858
1859
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001860E2fsprogs 1.30 (October 31, 2002)
1861=================================
1862
1863When resizing a filesystem, and inodes need to moved, resize2fs will
1864update the inode's ctime field, and the mtime field of the containing
1865directories, so that incremental backups using dump/restore will work
1866correctly.
1867
1868In order to avoid spurious errors, e2fsck wil check the last
1869superblock write time to determine whether or not it can safely use
1870the LOW_DTIME checks to determine if there are inodes on the orphan
1871inode linked list that had somehow gotten disconnected. (Addresses
1872Sourceforge bug #620980)
1873
1874Partition in /proc/partitions that being with the string "lvm" are
1875considered real partitions even if they do not end with a number.
1876
1877Fixed a bug in the the uuid generation function, where if /dev/urandom
1878is not present, but /dev/random is, and there isn't sufficient
1879entropy, the get_random_byte function could spin a loop forever.
1880
1881E2fsck, mke2fs, etc. will now reliably notice when image files are
1882mounted using the loopback interface. (Addresses Sourceforge bug
1883#619119)
1884
1885When flushing buffers (as is done by badblocks, for example) check to
1886see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
1887FDFLUSH ioctl which causes the MD device driver which causes confusing
1888syslog messages about obselete ioctl messages. (Addresses Sourceforge
1889bug #545832).
1890
1891Debugfs's write command now checks to see if the destination filename
1892exists before creating it. (Addresses Sourceforge bug #478195.)
1893
1894When installing man pages, search for compressed man pages using all
1895commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
1896
1897Fixed a bug in fsck where multiple filesystems specified on the
1898command were not being checked in parallel due to a logic bug
1899introduced to support the FSCK_MAX_INST environment variable.
1900
1901We have added a new superblock field, s_mkfs_time, which indicates
1902when a filesystem was created. It is set via mke2fs, and printed out
1903by dumpe2fs, but is not actually touched by the kernel.
1904
1905Dumpe2fs has been made more robust by not aborting if there is an
1906error reading the block/inode bitmaps; instead it will still print out
1907the location of the block/inode bitmaps and inode table.
1908
1909Add support for the an alternative block group descriptor layout which
1910allows for on-line resizing without needing to prepare the filesystem
1911in advance. (This is the incomat feature flag meta_bg.)
1912
1913Add support for storing default mount options in the superblock, so
1914that the filesystem can be mounted with specific mount options without
1915needing to specify them on the mount command line or in the /etc/fstab
1916file.
1917
1918Add support for a new inode flag, which is to be used for indicating
1919the top of directory hierarchies for the Orlov block allocator.
1920
1921Fix e2fsck so that if it creates the lost+found directory, it does so
1922with the more apporpriate permissions of 0700. Also change
1923mklost+found so that it also creates the directory 0700.
1924
1925Fixed format bug in e2fsck if NLS is in use.
1926
1927Add a German translation for e2fsprogs's NLS support.
1928
1929Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
1930the beginning of the inode table. This won't matter much, since if
1931there is a bad block at the beginning of the inode table, the root
1932directory won't be available. But at least e2fsck won't crash in this
1933case.
1934
1935Fixed endian problems in the htree code for e2fsck and debugfs.
1936
1937When byte-swapping a filesystem on a PPC architecture, byte-swap the
1938bitmaps since the historical big-endian ext2 variant had byte-swapped
1939bitmaps, and the ext2fs library assumes this. This fixes the
1940regression test suite on PPC machines.
1941
1942Fix e2image so that it handles a bad block in the inode table
1943appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04001944
1945E2fsck now uses a more sophisticated algorithm to salvage corrupted
1946directories that recovers more information in the corrupted directory
1947block.
1948
1949E2fsck now performs additional consistency checks on indexed (HTREE)
1950directories.
1951
1952Fix bug where efsck might get confused about whether a completely
1953empty directory block is an empty leaf block or an interior htree
1954node. This could cause e2fsck to get confused into think that a valid
1955indexed directory was corrupted.
1956
1957E2fsck no longer creates an empty directory entry at the end of a
1958directory block when optimizing a directory. This would cause some
1959earlier versions of the dxdir kernel code to corrupt the directory
1960when attempting to split a node containing an empty directory entry.
1961
1962E2fsck could sometimes in rare circumstances leave the indexed flag
1963set after a small directory was optimized by compressing it instead of
1964indexing it. (This should never happen in real life, since
1965directories that small wouldn't have been indexed, but better safe
1966than sorry.)
1967
1968E2fsck now only updates the master superblock in all cases. This
1969slightly shortens its run time.
1970
1971Ext2ed can deal with directory entries of length 0; previously it
1972would get stuck in an infinite loop.
1973
1974Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
1975specifiers. (Sourceforge patch #613447)
1976
1977Badblocks will now work correctly on read-only devices such as
1978CD-ROM's. (Sourceforge patch #600451)
1979
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001980Updated and clarified man pages. (Addresses Debian bug #167108)

Theodore Ts'oc6633052002-09-24 01:26:50 -04001983E2fsprogs 1.29 (September 24, 2002)
1984===================================
1985
1986Fixed a bug in e2fsck which could corrupt a directory when optimizing
1987it (via the -D option) or rebuiliding the hash tree index with a 1 in
1988512 probability, due to a fence post error.
1989
1990Fixed a bug in the LVM support code which caused LABEL='xxx' not to
1991work correctly.
1992
1993Mke2fs now enables the directory indexing flag by default. (Since
1994this is a compatible feature flag, it's safe to do so.)
1995
1996Tune2fs will support setting the directory indexing feature flag. It
1997will automatically set up the default hash algorithm and hash seed
1998fields in the superblock.
1999
2000If the bone-headed user enters the root filesystem twice in
2001/etc/fstab, the -R option which skips the root filesystem will skip
2002all of them. (Addresses Debian bug #159423). Note! This is not a
2003precedent for dealing intelligently with any other kind of doubled
2004entry in /etc/fstab!
2005
2006
2007Programmer's notes:
2008-------------------
2009
2010Removed perror declaration in lib/et/internal.h. All modern systems
2011can be expected to define perror() these days. Besides, the lib/et
2012code wasn't using perror at all anyway. :-)

Theodore Ts'ob7bad612002-08-31 03:00:33 -04002015E2fsprogs 1.28 (August 31, 2002)
2016================================
2017
2018Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2019for setting the htree flag is not included yet, although it can be
2020manually turned on via the debugfs program.
2021
2022Clarified e2fsck error message which is printed when it cannot find
2023sufficient contiguous block when relcating filesystem metadata.
2024
2025Added support for building an EVMS plugin module for ext2/3. This
2026module is substantially the same as the EVMS module shipping with EVMS
20271.1, with one or two bugfixes. E2fsprogs can also build this plugin
2028for use with EVMS 1.0 (which did not include the ext2 plugin module),
2029if the configure --enable-old-evms flag is given.
2030
2031Fsck will search through EVMS volumes when trying to resolve
2032filesystem specifications such as LABEL=xxx or UUID=xxx.
2033
2034Added a new utility program, /sbin/findfs, which will return
2035filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2036the device name.
2037
2038Update and clarified various man pages. (addresses Debian Bug #145044,
2039#146437, #131350, #151990, #144621, #141938)
2040
2041If there are no filesystems specified on fsck's command line, fsck now
2042treat that as if the -As options were given. Previously it would
2043simply do nothing. (Addresses Debian Bug #153102)
2044
2045Mke2fs no longer treats a failure to be able to clear the MD signature
2046at the end of the filesystem as a fatal error. (Addresses Debian Bug
2047#155007)
2048
2049The e2p library functions (which are used by lsattr and chattr) now
2050double check to make sure the file is a regular file or directory
2051before attempting to use the ext2 ioctls. Some device drivers
2052unfortunately respond to the ext2 ioctl's with unknown behaviour.
2053(Addresses Debian Bug #152029).
2054
2055The extended attribute handling has been updated to correspond with
2056the latest V2 bestbits ACL code.
2057
2058Fixed bug in e2fsck which caused it to not clear the dtime field when
2059processing truncated inodes on the orphan list. This could cause data
2060loss(!) if a filesystem is rebooted before a truncate has been
2061committed.
2062
2063E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2064algorithms. This makes e2fsck much faster in the case of severely
2065corrupted filesystems where a large number of blocks are claimed by a
2066large number of inodes. (Thanks to the 2.5 IDE device driver for
2067inspiring this work.)
2068
2069Resize2fs has been significantly sped up when shrinking and expanding
2070a filesystem by a very small number of blocks (for example, when EVMS
2071is converting a partition to be an EVMS legacy volume).
2072
2073Added a new option to e2fsck, -D, which will optimize or compress all
2074of the directories in the filesystem.
2075
2076E2fsck now catches SIGINT and SIGTERM to make sure it will can
2077properly clean up and only exit at safe points. Fsck will pass
2078SIGINT/SIGTERM to its child processes, and wait until they have all
2079exited before it exits.
2080
2081The uuid parsing code in the uuid library now properly complains when
2082an illegally formated uuid is presented to it. (Addresses Debian bug
2083#152891)
2084
2085Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2086and 2.4.17, since the workaround can cause problems when using a 2.4
2087kernel with an old version of glibc built with the 2.2 headers.
2088
2089Fixed a bug in mke2fs where it wasn't properly clearing the initial
2090superblock used by other filesystems. (Addresses Debian bug #147256.)
2091
2092Added support for the synchronous directory feature written by Andrew
2093Morton.
2094
2095The debugfs program can delete directories using the rmdir command.
2096
2097Add support for 8k and 16k filesystems (for systems with page sizes
2098that are greater or equal to 8k or 16k, respectively). Note that
2099these filesystems can not be mounted on x86 systems, or other systems
2100with only 4k page sizes, due to limitations in the current Linux VM
2101code.
2102
2103Resize2fs requires that the filesystem state be valid and have no
2104errors; otherwise, e2fsck -f must be run first. (Previously it simply
2105required that the last fsck time be greater than the last mount time.)
2106
2107Configure now defaults the man pages directory to /usr/share/man on
2108Linux systems.
2109
2110E2fsck now offers to truncate inodes which contain too many blocks (so
2111that i_blocks would overflow. Also fixed handling of large sparse
2112files.
2113
2114E2fsck now more completely checks for symlink validity, including
2115requiring NULL termination and length checks.
2116
2117E2fsck will offer to try forcing a disk write to remap a bad block
2118after finding a read error when reading a filesystem metadata block.
2119
2120Fixed a bug in debugfs which caused the -b and -s options to crash
2121debugfs, as well as breaking the testb, setb, and clearb functions.
2122
2123Added a bmap command to debugfs which calculates the logical to
2124physical block mapping for a particular inode.
2125
2126Fixed a bug in code which checked to see if a device was mounted which
2127sometimes (rarely) failed in the case of a plain file.
2128
2129Fixed a bug in resize2fs where when it reported an error, it would
2130print a message erroneously indicating that the filesystem had been
2131resized before it aborted.
2132
2133When resizing a plain file which is smaller than the requested size,
2134resize2fs will attempt to extended the file so that programs like
2135e2fsck will not complain that the file is too small.
2136
2137Resize2fs will print the actual new size of the filesystem when it is
2138finished resizing.
2139
2140Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2141information on big-endian systems.
2142
2143
2144Programmer's notes:
2145-------------------
2146
2147Fixed collisions with C++ reserved words.
2148
2149Added portability fixes for building e2fsprogs on the HURD and AIX.
2150
2151Added the ext2ed program for creation of test cases. (ext2ed has many
2152limitations and bugs which make it unsuitable for production use.)
2153
2154The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2155flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2156name_len field is byte swampped on big-endian machines, since in the
2157V2 structure, name_len is a char field which is doesn't need to be
2158byte swapped --- except if an old-style kernel had byte-swapped the
2159name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -05002162E2fsprogs 1.27 (March 8, 2002)
2163==============================
2164
2165The warning messages for mke2fs now go to standard error.
2166
2167Fixed to make sure "make check" runs all of the test programs with
2168LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2169
2170The mke2fs program checks the boot sector for the BSD disk label, and
2171avoids erasing it if it is there.
2172
2173Fixed a bug in e2fsck which caused it to core dump if the journal
2174inode was missing when it was supposed to be there.
2175
2176E2fsck now prints ranges in pass 5 when printing deltas for the block
2177and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002178
2179Debugfs's "ls -l" command now will print out the file type information
2180in the directory entry.
2181
2182Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2183mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2184
2185Debugfs can now examine the experimental directory indexing
2186information.
2187
Theodore Ts'oa471ac52002-03-05 03:37:06 -05002188Fixed bug in debugfs which caused it to core dump if modify_inode is
2189called without an open filesystem.
2190
2191The debugfs lsdel command now runs its output through a pager first.
2192
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002193When installing manual pages, remove the compressed manual pages first.
2194
2195Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2196
2197Fix the 2.4 resource limitation workaround introduced in 1.26 which
2198actually broke things on mips32, sparc32, and Alpha platforms.
2199
Theodore Ts'oa471ac52002-03-05 03:37:06 -05002200Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2201(which is required by the newer libintl libraries).
2202
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002203Programmer's notes:
2204-------------------
2205
Theodore Ts'oa8e77242002-03-08 03:12:14 -05002206Fixed various gcc -Wall complaints.
2207
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05002208Fixed a few memory leaks in the e2fsck journaling code, and in the
2209ismounted code checking for a swap device.
2210
2211Add new inode I/O abstraction interface which exports an inode as
2212an I/O object.
2213
2214Exported ext2_file_flush as a public interface.
2215
2216In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
2217
2218Lots of small random portability fixes to make e2fsprogs build under
2219AIX --- even without the 5L compatibility toolkit, and even using the
2220uber-crippled AIX native C compiler.
2221
2222
Theodore Ts'o06987392002-02-03 01:36:54 -05002223E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002224=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002225
Theodore Ts'o446314f2001-12-24 15:22:27 -05002226Dumpe2fs will keep going now if the bad block inode can't be read.
2227(Previously it stopped with a fatal error.)
2228
2229E2fsck will now give an opportunity to run the journal even if the
2230recovery flag is not set. This is the default behaviour if e2fsck is
2231using a backup superblock, since the needs_recovery flag will never be
2232set in the backup superblock copies.
2233
2234E2fsck now automatically finds the backup superblock/group descriptors
2235even when the primary superblock is completely destroyed for 2k and 4k
2236filesystems. (Previously it just guessed/assumed that we were dealing
2237with a 1k filesystem in that case, and users had to manually specify
2238the backup superblock number.)
2239
2240Fixed a bug in e2fsck where it dereferences a null pointer when there
2241is a problem opening a filesystem in preen mode.
2242
2243E2fsck now handles external journals correctly; previously it trashed
2244the external journal device if the journal needed to be replayed.
2245
2246Work around ulimit incompatibility problem caused by recent 2.4
2247kernels; the unix IO module will automatically try to set any resource
2248limits to be infinite on startup.
2249
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002250Fixed a bug in e2fsck where it wasn't allocating a new block or inode
2251bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04002252 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002253
2254E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
2255clearing the new V2 fields if they do not make sense or if the ext3
2256superblock is version 1 superblock.
2257
2258E2fsck will automatically relocate the ext3 journal from a visible
2259file (i.e., /.journal) to an hidden inode if the filesystem has been
2260opened read/write. This allows the users to add a journal while the
2261filesystem is mounted, but the next time the system is rebooted, the
2262journal file will disappear. This avoids problems with backups,
2263stupid operators with superuser bits, etc.
2264
2265Fix a bug in fsck where it would not support a filesystem type of
2266"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
2267
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002268Fsck now supports fstab entries of the form "ext3,ext2". It will also
2269automatically identify reiserfs filesystems.
2270
2271The number of processes spawned by fsck can now be limited using the
2272FSCK_MAX_INST environment variable.
2273
Theodore Ts'o446314f2001-12-24 15:22:27 -05002274Fsck now searchs the LVM proc hierarchy to find logical volumes which
2275should be searched for UUID and label information.
2276
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002277Work around a bug in 2.4.10+ kernels by trying to unset the filesize
2278limit if at all possible, when opening a block device. (The filesize
2279limit shouldn't be applied against writes to a block device.)
2280
Theodore Ts'o446314f2001-12-24 15:22:27 -05002281In mke2fs and e2fsck, specifying the -c option twice will now do
2282a read/write test on the disk. Update the man pages to encourage
2283using the -c option, and to discouraging running badblocks separately,
2284since users tend to forget to set the blocksize when running
2285badblocks.
2286
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002287Mke2fs now automatically clears the immutable attribute on a
2288pre-existing .journal file left over from a previous failed attempt to
2289add a journal to an alreadyy-mounted filesystem.
2290
2291Fixed mke2fs's exit codes to consistently indicate when the mke2fs
2292operation failed.
2293
Theodore Ts'o446314f2001-12-24 15:22:27 -05002294Mke2fs now creates the lost+found directory with permissions of 0700,
2295so that files that had previously lived in protected directory are
2296safe if they get dropped in lost+found and the system administrator
2297doesn't deal with immediately. (Addresses Debian #bug 118443)
2298
2299Mke2fs and e2fsck (and all programs that use the
2300ext2fs_check_if_mounted function) will now properly identify that a
2301device is mounted, even in cases where devfs has confused things with
2302multiple devices names with the same identity, or if a dim-witted
2303system administrator has done something stupid like creating device
2304file aliases in their home directory. Also now checks for swap devices
2305by using /proc/swaps. (Addresses Debian bug #106622)
2306
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002307Added a new option (-T) to tune2fs which sets the time a filesystem
2308was last checked.
2309
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002310Speed up e2image when creating sparse raw image files by optimizing
2311away excess lseek() system calls.
2312
2313Fix support of large (> 2GB) files when used as a filesystem in
2314mke2fs, tune2fs, debugfs, and findsuper.
2315
2316Debugfs's stat and icheck commands now properly deals with large (>
23172GB) files.
2318
2319Debugfs's set_super_value command now prints out the list of valid
2320superblock fields which can be set using the command.
2321
Theodore Ts'o446314f2001-12-24 15:22:27 -05002322Debugfs's rm and kill_file command now updates the superblock free block
2323and inode counts, thus keeping the filesystem consistent.
2324
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002325Debugfs's lsdel command now takes an optional argument which allows
2326the user to only see the most recently deleted files.
2327
2328A new command (undel) was added to debugfs which automates
2329undeleting a deleted inode and linking it back to a directory.
2330
2331Debugfs's ls command now takes a new option, -d, which lists
2332deleted directory entries.
2333
2334Debugfs's testb, freeb, setb, and find_free_block commands now take an
2335optional count argument.
2336
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002337Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
2338be used to signal that a particular inode should not be eligible for
2339tail-merging --- this is needed for programs like LILO.
2340
2341The findsuper (an unreleased, uninstalled utility program) has been
2342improved to add extra validity checks and to add a progress meter.
2343(It is still an unsupported program; the officially supported way to
2344recover from a trashed partition table is to use gpart; findsuper is
2345for wizards only. :-)
2346
2347Debugfs was fixed to compile with "configure --disable-swapfs".
2348
Theodore Ts'o446314f2001-12-24 15:22:27 -05002349Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05002350
2351Added new translation file for Turkish.
2352
Theodore Ts'o446314f2001-12-24 15:22:27 -05002353Programmer's notes:
2354-------------------
2355
2356Fix general gcc -Wall complaints.
2357
2358E2fsprogs (mostly) works with the dietlibc.
2359
2360The programming texinfo file has been expanded to include description
2361of additional libext2fs functions. (Still not compeltely done, but a
2362lot of the more important functions have been documented.)
2363
2364Added a umask structure to struct_ext2_filsys, which currently only
2365modifies the behaviour of ext2fs_mkdir(), but if we add any file
2366creation functions to libext2fs, we should also make sure they respect
2367the umask setting.
2368
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05002369The build-rpm script was fixed to be a bit more safe.
2370
2371The tests' Makefile now has a way of automating test case creation
2372for e2fsck, using "make testnew".
2373
2374Created a new function, ext2fs_dir_iterate2 which passes more
2375information to the callback function (identical to the one used by
2376ext2fs_dblist_dir_iterate). The directory iterator functions take a
2377new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
2378directory entries. If the directory entry is deleted, the callback
2379function will be called with the entry paraemter set to
2380DIRENT_DELETED_FILE.
2381
2382Added new functions, ext2fs_inode_alloc_stats and
2383ext2fs_block_alloc_stats, which takes updates block/inode allocation
2384statistics in the bitmaps, block group descriptors, and superblock
2385when inodes or blocks are allocated or deallocated.

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04002388E2fsprogs 1.25 (September 20, 2001)
2389===================================
2390
2391This is primarily a bug-fix release; no new features were added, but
2392there are a number of embarassing bug fixes and cleanups applied.
2393
2394Fix a bug mke2fs which causes stack garbage to be written to disk when
2395zapping disk sectors. (This bug could cause mke2fs to core dump for
2396some kernels, I suspect with security enhancement patches.)
2397
2398Remove unneeded #include of <linux/config.h> which was breaking
2399building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
2400
2401Updated tune2fs man page to reflect the fact that adding or removing a
2402journal doesn't require running e2fsck.
2403
2404Remove use of AC_REQUIRE from autoconf which had been used to prevent
2405AC_CANONICAL_HOST from being called twice; unfortunately this causes
2406recent autoconf to bomb out since they don't allow AC_REQUIRE to be
2407used outside of autoconf macros. Fortunately, it doesn't seem to be
2408necessary any more, anyway.
2409
2410E2fsck will now not fall back to an alternate superblock if the user
2411specifies the superblock location explicitly on the command-line.
2412This allows easier recovery from a situation where the primary
2413superblock and block groups are slightly corrupted, but the backup
2414superblocks are completely broken.
2415
2416Fix problem which caused compile_et and mk_cmds to blow up if
2417e2fsprogs was in a directory with a pathname that contained spaces.
2418
2419We are now more paranoid about checking the entry in /etc/mtab to make
2420sure the filesystem is really mounted, since some broken distributions
2421(read: Slackware) don't initialize /etc/mtab before checking non-root
2422filesystems. (Slackware also doesn't check the root filesystem
2423separately, and reboot if the root filesystem had changes applied to
2424it, which is dangerous and broken, but there's nothing I can do about
2425that.)
2426
2427Make UUID library C++ friendly by adding appropriate extern "C"
2428declarations and using const in the function declarations.
2429
2430Fix up the com_err texinfo file so that it can product a valid info
2431file (previously, it could only be used to generate paper
2432documentation using texinfo.tex).
2433
2434
Theodore Ts'ofb707752001-09-04 15:00:37 -04002435E2fsprogs 1.24a (September 2, 2001)
2436===================================
2437
2438Fix brown-paper bug in mke2fs which caused it to segfault when
2439printing the version string.
2440
2441
Theodore Ts'o109624a2001-08-31 00:59:55 -04002442E2fsprogs 1.24 (August 30, 2001)
2443================================
2444
2445Revert the BLKGETSIZE64 support, since for some distributions, this
2446ioctl has been used by an unofficial kernel patch to update the last
2447sector on the disk, and this was causing disk corruption problems as a
2448result.
2449
2450Mke2fs is now more careful about zapping swap space signatures and
2451other filesystem/raid superblock magic values so that programs like
2452mount who try to use hueristics to determine the filesystem type of a
2453partition are less likely to be confused.
2454
2455E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
2456regular file (since Andreas Dilger's on-line resizing tools will set
2457its mode bits).
2458
2459Fixed some minor texinfo, man pages nits for spelling errors,
2460texinfo warnings, etc. (Addresses Debian bug #110621.)
2461
2462E2fsprogs program no longer print the filesystem version number
2463(i.e. 0.5b), since it only confuses people and doesn't serve any real
2464purpose.
2465
2466E2fsck will once again compile under libc5, since it will supply its
2467own version of strnlen if necesssary.
2468
2469mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
2470when specifying the external journal device. tune2fs will also search
2471devices looking for the externla journal debice when removing.
2472
2473E2fsprogs 1.23 (August 15, 2001)
2474================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002475
2476Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04002477correctly handle a filesystem with EA's and check the EA blocks for
2478corruptions.
2479
Theodore Ts'od494bba2001-08-09 06:14:42 -04002480E2fsck's symlink sanity checking has been cleaned up. It now checks
2481the i_size value of fast symlinks, and checks for immutable flags
2482being set of symlinks, etc.
2483
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002484E2fsck now offers to clear inodes which are special files that have a
2485non-zero i_blocks or i_size field. (The i_size field check was in the
2486previous version of the code, but due to a bug it didn't offer to
2487clear the inode unless i_size and i_size_high were both non-zero.)
2488
Theodore Ts'od494bba2001-08-09 06:14:42 -04002489E2image can now create "raw" image files, which only contain the
2490filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
2491debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04002492
2493Add support for the 64-bit block device patches.
2494
2495Fixed bugs in creating external journals with a 1k blocksize.
2496
Theodore Ts'od494bba2001-08-09 06:14:42 -04002497Add initial support for external journals (so long as the external
2498journal only supports a single filesystem) in e2fsck.
2499
2500Remove requirement for needing to run fsck on a filesystem after
2501removing a journal (either internal or external).
2502
Theodore Ts'obf16d102001-07-27 22:20:06 -04002503The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002504
2505Speed up the check of an ext3 filesystems by avoiding a needless flush
2506of all of the superblock and block group descriptors.
2507
Theodore Ts'od494bba2001-08-09 06:14:42 -04002508Speed up creating an internal journal using tune2fs in the case where
2509the filesystem has a lot blocks already allocated.
2510
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002511Tune2fs has been fixed to make sure that only error messages go to
2512stderr, and normal message go to stdout. (Addresses Debian bug #108555)
2513
Theodore Ts'od494bba2001-08-09 06:14:42 -04002514Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002515now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04002516
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002517Add support in fsck for the filesystem type "auto".
2518
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002519Fsck -A will not try to interpret device names for filesystems which
2520have a pass number is 0. (Addresses Debian bug #106696).
2521
2522Fsck prints a warning message if now valid filesystems are passed to
2523it. (Addresses Debian Bug #107458.)
2524
Theodore Ts'o9249d982001-07-20 18:14:10 -04002525E2fsck now gives an explicit warning if there filesystem still has
2526errors at the end of the run. (Addresses Debian bug #104502)
2527
Theodore Ts'od494bba2001-08-09 06:14:42 -04002528E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002529reflects an error. E2fsck will also not run the orphan list if the
2530filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04002531
2532E2fsck now prints the number of large files when given the -v option.
2533
2534Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04002535
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002536Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04002537
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002538
Theodore Ts'o19d6b542001-06-23 00:13:09 -04002539E2fsprogs 1.22 (June 22, 2001)
2540==============================
2541
2542Fixed a bug in e2fsck's handling of orphan inodes which are special
2543files (i.e., block/character device files, named FIFO's, etc.).
2544
2545Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
2546tune2fs to fail at adding a journal to a mounted filesystem.
2547
2548Fixed a few big-endian bugs in e2fsprogs
2549 * The directory block functions were accidentally reporting
2550 some directories as corrupted when they weren't.
2551 * If e2fsprogs is compiled --disable-swapfs, the C language
2552 equivalents weren't being included for big-endian platforms.
2553 (Fixes Debian bug #101686).
2554
2555Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
2556
2557Programmer's notes:
2558-------------------
2559
2560Use platform independent method of defining the BLKFLSBUF and FDFLUSH
2561ioctls, and allow them to be defined for non-i386 platforms.
2562
2563The uuid.h header file is now protected against multiple inclusions.
2564
2565E2fsprogs is now being developed using BitKeeper. Changed the test
2566scripts to deal with BK's stripping CR characgters from text files,
2567and changed the top-level Makefile.in to avoid including BitKeeper
2568files when generating the source tarball.
2569
2570
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002571E2fsprogs 1.21 (June 15, 2001)
2572==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00002573
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002574Added new configure flags which allow a subset e2fsprogs to be built;
2575this is most useful for boot floopies, since the resulting shared
2576libraries and programs are slimmed down by removing features that
2577aren't necessary for a boot floppy. The new flags that were added
2578are: --disable-swapfs, which removes support for byte swapping old
2579legacy PPC/68k filesystems, --disable-debugfs, which removes support
2580for debugfs from the libext2fs library, --disable-imager, which
2581removes support for the e2image program, and --disable-resizer, which
2582removes support for resize2fs.
2583
2584E2fsck now prints the number of mounts or days elapsed since the last
2585check when e2fsck is forced to check an otherwise clean filesystem.
2586
2587Tune2fs now prints an informative message about how often a filesystem
2588will be checked when adding a journal to the filesystem, to remind the
2589user that he/she may want to adjust those parameters using tune2fs
2590-c/-i.
2591
2592Worked around hurd brain-damage which causes e2fsck to sometimes
2593believe a filesystem is the root filesystem based on device numbers
2594(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
2595violation).
2596
2597Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
2598erroneous error with the -F option was specified.
2599
2600Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002601ext3 0.7a.
2602
Theodore Ts'o767de092001-06-02 01:20:18 +00002603Fixed two bugs in e2fsck's handling of dup block handling, dealing
2604with relatively uncommon edge cases: a directory with an indirect
2605block which is claimed by another file, and when the last inode in the
2606filesystem has blocks claimed by another file.
2607
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00002608E2fsck now checks to see if the i_size field of a fast symlink is too
2609big, and offers to clear the symlink if so.
2610
2611E2fsck now checks to see if i_size_high of special files is non-zero,
2612and offers to clear i_size_high.
2613
Theodore Ts'o767de092001-06-02 01:20:18 +00002614Fix e2fsck's handling of incompatible journal flags so that the user
2615has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00002616entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00002617
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002618Fixed a bug in fsck which could cause it to core dump if a mix of
2619standard and non-standard device names are used in /etc/fstab.
2620(Debian bug #100559)
2621
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002622Fixed a bug in debugfs which caused read errors when copying a file to
2623not be noticed.
2624
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002625The debugfs set_super_value command can now modify the s_lastcheck field.
2626
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002627Fixed a bug in lsattr and chattr which was accidentally introduced in
26281.20 to support > 2GB files; both lsattr and chattr wasn't reading
2629directories correctly because the change modified the layout of struct
2630dirent to be incompatible with the libe2p shared library.
2631
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002632Cleaned up the mke2fs manual page and included a discussion about why
2633it's good to periodically check the filesystem even when journaling is
2634enabled.
2635
Theodore Ts'o767de092001-06-02 01:20:18 +00002636Programmer's notes:
2637-------------------
2638
2639Fix general gcc -Wall complaints.
2640
2641The types needed by the ext2 header files are now provided by
2642lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
2643
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002644Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002645in ext2_types.h. Also, if linux/types.h has already been defined,
2646don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002647
Theodore Ts'o767de092001-06-02 01:20:18 +00002648Fixed make depend script so that it automatically corrects the
2649pathname cleanups performed by make -M, so I don't have to fix them up
2650by hand.
2651
2652Fixed the d_loaddump test case to be more robust, and not depend on
2653bash'isms.
2654
2655Removed debugfs's dependence on pread(), which was accidentally
2656intrudced in e2fsprogs 1.20
2657
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002658Fixed a performance bug in the libext2fs's icount routine; the size
2659estimate of the icount array was incorrectly being calculated.
2660
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002661Removed use of the badblocks compatibility functions in the e2fsprogs
2662programs.
2663
2664Added paranoia code which protects against strange cases where /etc
2665isn't on the root filesystem, or if /etc/mtab doesn't exist.
2666
2667The header file ext2_types.h is now installed.
2668
2669Autoconf is used to determine when we are on big-endian machines,
2670instead of doing run-time tests, to save a few bytes of code.
2671
2672The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
2673functions are no longer inline functions, which saves space and
2674doesn't really cost any real performance.
2675
2676The ext2fs library no longer depends on the e2p library. (What need
2677there was of it --- namely, fsetflags, was coded in-line).
2678
2679Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
2680when the user is stupid and tries compiling the package using "make
2681install" as root.
2682
2683Miscellaneous code cleanups:
2684 * Added missing files from Makefile.in's SRCS file, so that
2685 their dependencies would be properly calculated.
2686 * Removed redundant code
2687 * Fixed comments in code
2688 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002691E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002692=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00002693
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002694Add support for replaying the ext3 journal purely in user mode,
2695including handling the orphaned inode list. Used code contributed by
2696Andreas Dilger, with bug fixes and the orphaned inode handling done
2697by Theodore Ts'o.
2698
2699The mke2fs and tune2fs programs can create or modify a filesystem to
2700include an ext3 journal. Tune2fs also can be used to remove an ext3
2701journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002702
2703E2fsck will now check for the existence of a linked list of orphan
2704inodes in the superblock, and clear those inodes before starting the
2705rest of the filesystem check (but after the journal playback).
2706
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002707E2fsck now validates the file descriptor passed to the -C option,
2708which saves against the completion bar getting written to an
2709unexpected location, such as the disk being checked. (Debian
2710bug/wishlist #55220)
2711
2712E2fsck will now bump the filesystem revision number from zero to one
2713if any of the compatibility bits are set.
2714
2715Fixed a bug where a badly corrupted directory on a big endian system
2716could cause e2fsck to die with a bus error. The
2717ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
2718the ext2 library now does alignment sanity checks on the rec_len field
2719of the directory entry before using it.
2720
2721The ext2 library has been enhanced to make tune2fs safe to run on
2722mounted filesystems. (Users could usually get away with using tune2fs
2723on mounted filesystems before, but with the advent of ext3 and
2724journaling, it became important to make tune2fs was *really* safe for
2725use even when the filesystem being modified is mounted.) E2label is
2726now implemented by tune2fs using an argv[0] dispatch, so that e2label
2727is also now safe for use on mounted filesystems.
2728
2729Added a new program, e2image, which creates a backup of critical ext2
2730filesystem data structures. The generated image file can be examined
2731using dumpe2fs and debugfs. In the future, e2fsck will be able to use
2732the image file to help recover very badly damaged filesystems.
2733
2734Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
2735no longer cause e2fsck to bomb out. Also treat files > 2GB as being
2736large file when deciding whether or not the filesystem has large files.
2737
2738Fixed lsattr and chattr so that they work correctly on large files.
2739(Fixes Debian bug #72690.)
2740
2741Removed limitation in get_device_size() which imposed a one terrabyte
2742filesystem limitation. (Most 2.2 kernels still have a signed int
2743problem which cause 1 TB block device limitation. Fortunately, the
2744kernel patches to fix this are much easier than fixing the 2TB
2745limitation in the kernel. :-)
2746
2747A max_mount_count of zero is now treated as if no mount count were
2748set. (Previously, no mount count was indicated by using -1, and a
2749mount count of zero caused e2fsck to always be run.)
2750
Theodore Ts'o77648562001-05-14 13:04:44 +00002751Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002752
2753Mke2fs now adds some randomness in s_max_mount_count so that multiple
2754filesystems won't be all checked at the same time under normal
2755operations.
2756
Theodore Ts'o5570a652000-08-21 01:23:39 +00002757Fixed bug in the progress bar printing code which could cause e2fsck
2758to core dump on an illegal filesystem.
2759
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002760Fixed bug in fsck which could allow more than one instance of e2fsck
2761to be printing a progress bar. (Debian bug #65267)
2762
Theodore Ts'o5570a652000-08-21 01:23:39 +00002763Fsck using a UUID or a LABEL specifier will work even if devfs is
2764compiled into the kernel and not mounted. If the pathnames in
2765/proc/partitions are incorrect, fsck will search /dev for the correct
2766device (using the new ext2fs_find_block_device library function).
2767Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002768found when they are in use. Support has also been added to support
2769additional IDE disks and the DAC 960 device names. (Debian bug #94159)
2770
2771Fixed a bug in fsck which caused it not deal properly with 16
2772byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002773
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002774Fsck's -t option has been made a lot more flexible. The semantics for
2775what happens if a comma-separated list to fsck has been regularized,
2776and it is now possible to filter what filesystems will get checked
2777based what is in the filesystem's fstab entry's option field. (Debian
2778bug #89483.)
2779
Theodore Ts'o5570a652000-08-21 01:23:39 +00002780The dumpe2fs program can now print out the group description
2781information in hex, and also prints the location of the superblock and
2782block group descriptor for those block groups that have them.
2783
2784Mke2fs now clears the ext2 superblock before it starts creating a
2785filesystem, so that the superblock magic number is only written if the
2786filesystem creation process successfully completes.
2787
2788The debugfs program's stat command now pretty-prints the blocks used
2789by an inode so that it's more compact and informative.
2790
2791The debugfs stats command now uses the same libe2p code (which is used
2792by dumpe2fs) to print the superblock header information. This is more
2793complete, and it avoids a bit of code duplication.
2794
2795Added a new debugfs command, set_super_value (ssv) which allows the
2796user to set arbitrary superblock fields.
2797
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002798Debugfs was extended to support inode numbers in hex (by prefixing
2799them with 0x), and so that modify_inode can set the inode generation
2800number. Also, there is now a new function command called logdump
2801which will dump an ext3 journal.
2802
2803Fixed a bug in debugfs so that quitting out of the pager doesn't kill
2804debugfs.
2805
2806Debugfs's dump command now stops immediately upon reporting a disk
2807read error. (Fixed a bug in ext2fs_file_read library routine which
2808caused debugfs not to stop.) (Debian bug #79163)
2809
2810On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
2811checked before /etc/mtab is used, since /proc/mounts is more likely to
2812be accurate.
2813
2814Added portability fixes for Solaris and Linux/ia64.
2815
2816Various manual pages were clarified and cleaned up. (Fixed debian
2817bugs #63442, #67446, and #87216)
2818
Theodore Ts'o5570a652000-08-21 01:23:39 +00002819
2820Programmer's notes:
2821-------------------
2822
2823The e2fsck message printer now supports %Iu and %Ig, which will print
2824out the inode's user and group owners, respectively.
2825
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002826E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
2827that no longer dependent on the system having the correct version of
2828the kernel header files.
2829
Theodore Ts'o5570a652000-08-21 01:23:39 +00002830Added a new function to libext2, ext2fs_find_block_device(), which
2831searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
2832device given its device number.
2833
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002834Added a new function to libext2, ext2fs_sync_device, which centralizes
2835all of the places which might try to use the BLKFLSBUF or FDFLUSH
2836ioctls (and usually failing to define them since the system header
2837files don't usually do this for us, and we're trying to avoid usage of
2838kernel include files now).
2839
Theodore Ts'o5570a652000-08-21 01:23:39 +00002840Added new utility programs in tests/progs: random_exercise and
2841hold_inode. They aren't built by default; they're useful for
2842exercising ext3 filesystem code.
2843
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002844Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
2845the filesystem close functions to only update the superblock, and to
2846not touch the block group descriptors. Needed by tune2fs when
2847modifying a mounted filesystem.
2848
2849Got rid of struct ext2fs_sb and replaced it with the standard struct
2850ext2_super_block from include/linux/ext2_fs.h. Note: this may break
2851source (but not binary) compatibility of some users of the ext2
2852library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00002853replace of struct ext2fs_sb with struct ext2_super_block, and include
2854the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002855
2856The ino_t type has been renamed ext2_ino_t to protect applications
2857that attempt to compile -D_FILE_OFFSET_BITS=64, since this
2858inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
2859unexpected ABI change.
2860
2861The Makefiles have been reworked so that "make check" can be run from
2862the top-level Makefile.
2863
2864Fix general gcc -Wall complaints and removed dead code.
2865
2866Remove use of NOARGS, because we assume everyone does ANSI C these
2867days.
2868
2869Added build-rpm script from sct.
2870
2871New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
2872to support e2image.
2873
2874New function ext2fs_flush_icache which must be called if the
2875application program modifies the inode table blocks without going
2876through ext2fs_write_inode() interface.
2877
2878New ext2fs_check_mount_point() function, which will return the mount
2879point of a device if mounted.
2880
2881The io_channel abstraction now has an optional interface,
2882io_channel_write_range, which allows specific byte ranges to be
2883written.
2884
2885The unix_io IO channel now supports write-through caching, so that
2886journal creation is more efficient.
2887
2888Added x86 assembly language routines to support byte swapping, to
2889reduce executable size.
2890
2891Fixed bug in the utility program subst so that it's possible to
2892replace a substitution variable with a zero-length string.
2893
2894Fixed numbering e2fsck pass1 problem numbers; an extra zero had
2895slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002896
Theodore Ts'ob777e262000-07-27 01:39:23 +00002897E2fsprogs 1.19 (July 13, 2000)
2898==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00002899
2900Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00002901be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00002902
2903Add experimental support needed for the ext2 compression patches.
2904This requires compiling e2fsprogs with the --enable-compression flag
2905to the configure script.
2906
2907Added ext3 journalling support. E2fsck will run the journal (if
2908necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
2909installed as a symlink to e2fsck. Fsck has been taught about ext3,
2910and treats it the same as ext2 in terms of the progress bar logic.
2911Dumpe2fs will display the superblock journaling information if the
2912filesystem has a journal. The ext2 library will now permit opening an
2913ext3 filesystem with the recovery flag set. This is necessary for
2914on-line dump's to work correctly, but there may be issues with this
2915working well since ext3 is much less agressive about syncing blocks to
2916the filesystem, since they're safe on the journal.
2917
2918Tune2fs and e2fsck have been changed to allow the mount_count check to
2919be disabled by setting max_mount_count to -1. (This was already
2920supported by the kernel.)
2921
2922Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
2923are used for ext3 as well.
2924
2925Added internationalization support for e2fsprogs; must be enabled
2926by passing --enable-nls to configure.
2927
2928Always use the provided ext2fs header files to insulate ourselves from
2929kernel version changes. Which include files are used by e2fsprogs
2930have also been cleaned up to improve portability.
2931
2932Limit the number of times that e2fsck updates the progress bar so that
2933people who are booting using a 9600 baud console don't get swampped by
2934too many updates.
2935
2936Improved the loop detection algorithm in e2sck's pass #3 so that it is
2937much, much faster for large filesystems with a large number of
2938directories.
2939
2940The memory footprint for e2fsck is now slightly smaller than before.
2941
2942E2fsck now checks if special devices have a non-zero size, and offers
2943to clear the size field if it finds such an inode.
2944
2945E2fsck now checks if special devices have the append-only flag set,
2946and offers to clear the inode.
2947
2948E2fsck now properly handles some "should never fail" cases during a
2949bitmap copy in pass5.
2950
2951E2fsck now properly prints control characters in filenames as ^A .. ^Z.
2952
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002953E2fsck now calculates the correct location of the backup superblock in
2954the case of filesystem blocksizes > 1k.
2955
2956Fixed a bug in e2fsck's calculation of the number of inodes_per_block
2957which normally didn't cause problems under most filesystem parameters,
2958but could cause a valid superblock to be rejected in extreme cases.
2959Other checks for validating superblock values were made more
2960stringent.
2961
Theodore Ts'oab146762000-07-07 04:37:35 +00002962Added non-destructive write testing to the badblocks program, courtesy
2963of David Beattie. The badblocks also now has an option to input the
2964current set of bad blocks, so that known bad blocks are skipped to
2965speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00002966feature which causes badblocks to run until it has completed some
2967number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00002968
2969Badblocks now checks to see if the device is mounted and refuses to do
2970the tests involving writing to the device if it is mounted. Also,
2971badblocks now allows the number of blocks to be checked to be
2972defaulted to the size of the partition.
2973
2974Fixed a bug in fsck which didn't allow non-root users to be able to
2975check filesystems if there were any LABEL= or UUID= entries in
2976/etc/fstab.
2977
2978The Hurd doesn't support the filetype filesystem feature. The mke2fs
2979program now makes sure that for the Hurd, the filestype feature is
2980turned off. E2fsck will check to see if the filetype feature is
2981turned on for Hurd filesystems, and offer to turn off the feature.
2982
2983Mke2fs now has a safety check to make sure the number of blocks do not
2984exceed 32 bits even on a 64 bit platform.
2985
2986Really fixed a bug in fsck to allow "fsck -As" to run interactive
2987fsck's. (For those people who like to do interactive fsck's in the
2988/etc/rc scripts!?!)
2989
2990Debugfs has a few new features: the rdump command, which will do a
2991recursive dump of a directory and all of its contents, and the lcd
2992command which does a local chdir (much like the ftp command of the
2993same name). In addition, the debugfs program and the open_filesystem
2994command now takes three new options: -b and -s, which allows the
2995blocksize and superblock location to be specified, and the -c option
2996which is used in catastrophic situations where the block group
2997descriptors are corrupt. If the -c option is specified, debugfs will
2998skip trying to read in the block and inode bitmaps.
2999
3000Debufs's lsdel command was fixed to handle bad blocks in the inode
3001table.
3002
3003A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
30044 digit years.
3005
3006General improvements in error messages
3007
3008 - Mke2fs prints a sane error message if the partition size is zero
3009 (usually because the partition table wasn't reread by the
3010 kernel due to the partition being busy), instead of "invalid
3011 argument passed to ext2 library while initializing superblock".
3012
3013 - Fsck now prints more self-explanatory message if an invalid UUID=
3014 or LABEL= specification is passed to it.
3015
3016UUID library changed to use the LGPL.
3017
3018Fixed a bug in the UUID library where very rapid calls to the
3019time-based UUID generator could cause duplicate UUID's to be returned.
3020This was not a problem for e2fsprogs, but it could be a problem for
3021other users of the library.
3022
3023Make the UUID library more robust in the face of missing or an
3024improper /dev/urandom or /dev/random files.
3025
3026Added some random portability fixes for Solaris.
3027
3028Some minor man page updates.
3029
3030Fixed a memory leak in the ss library.
3031
3032
3033Programmer's notes:
3034-------------------
3035
3036We now try to use lseek64 and open64 from the LFS if possible.
3037
3038The 3rd parameter in e2p's print_flags is now a flags word, instead of
3039a boolean option.
3040
3041The mark and unmark bitmap functions now return the previous state of
3042the bit that was being changed, which is useful for some speed
3043optimizations.
3044
3045The following functions have been added to enhance the badblocks list
3046handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3047ext2fs_badblocks_equal.
3048
3049The ext2 header files now have the latest journalling fields to the
3050superblock.
3051
3052The ext2fs_mkdir function in libext2fs now properly backs out of error
3053conditions robustly.
3054
3055Cleaned up makefiles:
3056 - to cleanly compile with the -j flag.
3057 - so distclean removes all generated files.
3058 - so in case of an error while installing header files, the make aborts.
3059
3060Fix test_script so that it works correctly when compiling in the
3061source directory.
3062
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00003063The random UUID generation routine has been made slightly better in
3064the case where /dev/random doesn't exist. (Use of randomly-based UUID
3065is still not recommended if /dev/random doesn't exist, however; it's
3066better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00003067
3068Clean up the build process so it's more friendly in case of missing
3069directories.
3070
3071The ext2fs header file can now be #include'd into C++ programs.
3072
3073The e2p.h header file is now installed.
3074
3075Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3076
3077
3078
Theodore Ts'o24ded091999-11-10 15:56:16 +00003079E2fsprogs 1.18 (November 10, 1999)
3080==================================
3081
3082Fix a core dumping bug in e2fsck if an imagic inode is present or
3083(more rarely) if the filesystem is badly corrupted enough that e2fsck
3084has to restart pass 1 processing. E2fsck now closes the filesystem
3085before freeing a large number of its data structures, so in the case
3086of future memory faults, at least the fixed filesystem will be fully
3087written out.
3088
3089If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3090imagic inode, it will offer to clear the imagic flag.
3091
3092E2fsck will now offer to clear the immutable flag on special files
3093(device/socket/fifos) when running it in non-preen mode.
3094
3095E2fsck will now set the filetype when creating /lost+found, and when
3096connected orphaned inodes to /lost+found.
3097
3098Debugfs's ncheck and icheck commands now handles the case where there
3099are bad blocks in the inode table without bombing out.
3100
3101The badblocks list processing code has been made more efficiently for
3102appending a large number of (ordered) badblocks to the badblocks list.
3103
3104Some minor man page updates.
3105
3106Fsck now allows interactive e2fsck's when using fsck -As (not a common
3107mode, but some people like to do this in boot scripts for silly reasons).
3108
3109Programmer's notes:
3110-------------------
3111
3112The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3113with the problem code convention.
3114
3115The badblocks list regression test program has been updated to work
3116with previously made API name changes.
3117
3118The ext2fs_free() command now uses the new badblocks API to avoid
3119using the compatibility layer.
3120
3121Added new regression test cases; the run_e2fsck test script now
3122supports the ability for a test case to run a prepratory command
3123before running e2fsck.
3124
Theodore Ts'o28e11941999-10-26 18:17:20 +00003125E2fsprogs 1.17 (October 26, 1999)
3126=================================
3127
3128Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3129infinite loop.
3130
3131Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3132thus potentially causing problems if a binary UUID contained a NULL
3133character.
3134
3135E2fsck now uses stricter checks for directory entries in pass 2:
3136zero-length filenames are not allowed; neither are 8 byte long
3137directory entries.
3138
3139The debugfs "dirty" command now clears the filesystem valid bit.
3140(Previously this just set the dirty-as-in-needs-writing-out-to-disk
3141bit in the in-core superblock image. The new functionality is more
3142what the user expects, and is more useful.)
3143
3144Added a debugging hook to test parallel fsck; if the environment
3145variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3146will be checked in parallel when they normally would not be.
3147
3148Programmer's notes:
3149-------------------
3150
3151Fixed some #ifdef's for compilation under the Hurd OS.
3152
3153Fixed minor W2K compatibility problems.
3154
3155Fixed some miscellaneous GCC warnings.
3156
3157
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00003158E2fsprogs 1.16 (October 22, 1999)
3159=================================
3160
3161Fixed a race condition bug in fsck; when printing a progress bar, if
3162checking multiple filesystems in parallel, it was possible for fsck to
3163send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3164handler, which would cause it to terminate with a signal 10.
3165
3166E2fsck now properly handles filesystems that have the
3167INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3168filesystem into using or not using FILETYPE feature.
3169
3170E2fsck now properly handles filesystems that have the IMAGIC feature
3171turned on (this is used on Linux AFS servers).
3172
3173The mke2fs program now creates filesystems that have the filetype and
3174sparse_superblock features enabled by default, unless it is run on a
3175pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3176so there is now a new flag -O which allows the user to specify with
3177which features she would like to create the filesystem; "mke2fs -O
3178none" will create a filesystsem compatible with 2.0 kernels.
3179
3180The tune2fs program now has a -O option which allows the user to set
3181and reset "safe" filesystem features. Currently, the only ones which
3182allows to be modified are the filetype and sparse_superblock features.
3183Note setting or clearing either feature will require running e2fsck on
3184the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3185requires that there is enough free space on the filesystem for the
3186extra superblocks which will be created by e2fsck.)
3187
3188Debugfs can now set and print filesystem features in the superblock
3189using the "features" command. Dumpe2fs will print out the complete
3190set of features when listing the superblock.
3191
3192Dumpe2fs has new options -f (force) and -h (header-only).
3193
3194Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3195message to come up. This could happen when decrementing or
3196incrementing a link count could result in an overflow.
3197
3198Fixed a bug in e2fsck where the block count on the lost+found
3199directory would not be properly incremented when the directory was
3200expanded to the point where an indirect block needed to be allocated.
3201
3202E2fsck now makes some additional sanity checks on the superblock to
3203avoid crashing or giving a memory allocation error if some of the
3204values in the superblock are unresonable (but the superblock otherwise
3205looks valid).
3206
3207Fixed a bug in e2fsck where a very badly corrupted filesystem might
3208require two passes to completely fix the filesystem. This happened if
3209an inode claimed blocks that was part of the filesystem metadata
3210(typically, when garbage was written into an inode table or indirect
3211block, since this kind of filesystem corruption normally doesn't
3212happen otherwise).
3213
3214On the Alpha, glibc declares st_flags although it isn't actually used;
3215the configure script was improved to detect this case so that
3216e2fsprogs can avoid using the non-functional stat field.
3217
3218The manual pages were updated to use a more consistent formatting
3219style consistent with standard Unix man pages. Mke2fs's man page
3220added documentation for a few previously undocumented options.
3221
3222Fixed minor display bugs in tune2fs and mke2fs.
3223
3224Programmer's notes:
3225-------------------
3226
3227Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
3228
3229Added features to parse and print feature strings into the e2p library.
3230(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
3231
3232ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
3233whose directory entries contain proper filetype information if the
3234filesystem supports it.
3235
3236ext2fs_link() now uses the low 3 bits of its flags parameter to pass
3237the directory entry filetype information. This is used to set the
3238directory entry filetype information if the filesystem supports it.
3239
3240Fixed a bug in ext2fs_expand_dir() where the block count in a
3241directory's inode would not be properly incremented when the directory
3242was expanded to the point where an indirect block needed to be
3243allocated.
3244
3245
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003246E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003247==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003248
3249Add configuration checks so that e2fsprogs will compile cleanly on
3250Linux 2.3 kernels that have renamed i_version to i_generation.
3251
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003252E2fsck now prints a progress/completion bar (and not just a simple
3253spinner) if the -C0 option is requested or if it receives a SIGUSR1
3254signal. Fsck will automatically manage the (potentially muliple)
3255e2fsck processes to print completion bars if it is given a -C option,
3256with the right thing happening if multiple filesystems are being
3257checked in parallel.
3258
3259Mke2fs now has better automatic hueristics to determine the filesystem
3260parameters to be used for a particular filesystem. Added a new option
3261-T which allows the user to specify how the filesystem is to be used,
3262which helps mke2fs do a better job selecting the filesystem parameters.
3263
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003264Mke2fs now creates revision 1 filesystems by default, and with the
3265sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00003266not understood by Linux 2.0 kernels, so they will only allow read-only
3267mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003268
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003269Fix bug where if /dev/null couldn't be opened (should never happen),
3270e2fsck would hang in a tight loop.
3271
3272Make e2fsck handle the case where /lost+found isn't a directory.
3273
3274E2fsck now uses mallinfo if it exists to get accurate statistics about
3275its memory usage.
3276
3277Fix bug in e2fsck where it wouldn't check to see if a disconnected
3278inode had any problems before connecting it to /lost+found.
3279
3280Add check to e2fsck so it makes sure that total number of inodes in
3281the filesystem is a sane number.
3282
3283Fix fencepost error when clearing an the end of the block bitmap which
3284caused the last block in the bitmap not to get cleared.
3285
3286Cleaned up a number of messages in e2fsck:
3287 * The message "Group's #'s copy of the group descriptor..."
3288 was fixed so that the correct number would be displayed.
3289 * Added missing space in the "disk write-protected" error messsage
3290 * Cleaned up the error message printed when a non-interactive
3291 e2fsck needs to abort a check because the filesystem
3292 appears to be mounted.
3293
3294Added a new command-line utility, uuidgen, which will create and print
3295a UUID.
3296
3297Make debugfs's icheck command more robust by checking to make sure an
3298inode has valid blocks before interarting over the inode's blocks.
3299
3300UUID generation now uses a random-based scheme whenever possible to
3301prevent potential privacy problems.
3302
3303Man pages for all of the UUID functions in the lirbary were added.
3304
3305Fixed bug in fsck so it won't coredump if a filesystem not in
3306/etc/fstab is given to it.
3307
3308Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
3309that most of the other mount utilities understands.
3310
3311Mke2fs will make a filesystem even if it appears mounted if the force
3312option is given.
3313
3314Dumpe2fs has new command-line options which allow a filesystem expert
3315to specify the superblock and blocksize when opening a filesystem.
3316This is mainly useful when examining the remains of a toasted
3317filesystem.
3318
3319The badblocks program has been updated to display correctly on disks
3320with large block numbers.
3321
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00003322The badblocks program no longer gives spurious errors when errors
3323occur on non-block boundaries, which is common if the blocksize is
3324larger than 1k.
3325
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003326Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
3327MKE2FS_SYNC environment variable is set. This is to work around a VM
3328bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00003329to trigger it even using a 2.2 kernel, but hopefully it will not be
3330needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00003331
3332Fixed miscellaneous documentation and man pages.
3333
3334Programmer's notes:
3335-------------------
3336
3337Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
3338in e2fsck's pass1.c really should have been static.
3339
3340The return value of the uuid_compare() function was changed to make it
3341match with the convetions used by strcmp, memcmp, and Paul Leach's
3342UUID sample document.
3343
3344The "make depend" process has now been made more automated; it now
3345automatically word-wraps the dependencies, and only replaces source
3346Makefile.in if there has been a change in the dependencies. Also, a
3347top-level "make depend" now recurses through all the subdirectories
3348automatically.
3349
3350The Makefile in .../util has been changed so that subst is built using
3351the native C compiler during a cross-compilation, since the subst
3352program is only used during the build process. Also add an explicit
3353rule to build util/subst by cd'ing to the correct directory and
3354running Makefile.
3355
3356The man directories are defined in terms mandir, so that the configure
3357script can override the location of the manual pages.
3358
3359The config files have been updated to recognize new machine types for
3360both the i386 and alpha families.
3361
3362Fsck has been modified so that it will accurately create an
3363fsck_instance even when the noexecute flag is set. This allows for
3364accurate debugging of the fsck pass structure. Also, when the verbose
3365flag is given twice, fsck will print debugging information about when
3366fsck is waiting for jobs to finish.
3367
3368
Theodore Ts'o14790ed1999-01-12 23:32:52 +00003369E2fsprogs 1.14 (January 9, 1999)
3370================================
3371
3372Fix the fstab parsing code so that it can handle blank lines and
3373comment characters. Also, missing pass numbers need to be treated as
3374zero.
3375
3376Fixed a bug in e2fsck where under some circumstances (when e2fsck
3377needs to restart processing after fixing an egregious inconsistency)
3378it would try to access already freed memory.
3379
3380E2fsck now prints non-printable characters in directory entries and
3381pathnames using '^' and 'M-' notation.
3382
3383Fixed chattr so that it will ignore symbolic links when doing
3384recursive descent traversals. For both chattr and lsattr, no longer
3385print the version string unless the -V option is given.
3386
3387Allow the system administrator to directly specify the number of
3388inodes desired in the filesystem, for some special cases where this is
3389necessary.
3390
3391Fix portability problems so that e2fsprogs can be compiled under Linux
33921.2 systems and Solaris systems.
3393
3394Update the config.guess file with a more recent version that will
3395identify newer Linux platforms.
3396
3397Programmer's notes
3398------------------
3399
3400Ext2fs_read_inode and ext2fs_write_inode will now return an error if
3401an inode number of zero is passed to them.
3402
Theodore Ts'o556ad131998-12-19 08:10:58 +00003403E2fsprogs 1.13 (December 15, 1998)
3404==================================
3405
3406Fixed a bug in debugfs where an error messages weren't getting printed
3407when the ext2 library routines to read inodes returned errors in the
3408stat, cmri and rm commands.
3409
3410Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
3411provided, it won't create an inode table smaller than the minimum
3412number of inodes required for a proper ext2 filesystem.
3413
3414Fsck now parses the /etc/fstab file directly (instead of using
3415getmntent()), so that it can distinguish between a missing pass number
3416field and pass number field of zero. This caused problems for
3417diskless workstations where all of the filesystems in /etc/fstab have
3418an explicit pass number of zero, and fsck could not distinguish this
3419from a /etc/fstab file with missing pass numbers.
3420
3421E2fsck will create a /lost+found directory if there isn't one in the
3422filesystem, since it's safer to create the lost+found directory before
3423it's needed.
3424
3425Fixed e2fsck so that it would detect bogus immutable inodes which
3426happen to be sockets and FIFO files, and offer to clear them.
3427
3428If a filesystem has multiple reasons why it needs to be checked, and
3429one of the reasons is that it is uncleanly mounted, e2fsck will print
3430that as the reason why the filesystem is being checked.
3431
3432Cleaned up the output routines of mke2fs so that it doesn't overflow
3433an 80 column display when formating really big filesystems.
3434
3435Added a sanity check to e2fsck to make sure that file descriptors 0,
34361, 2 are open before opening the hard disk. This avoids a problem
3437where a broken program might exec e2fsck with those file descriptors
3438closed, which would cause disastrous results if the kernel returns a
3439file descriptor for the block device which is also used by FILE *
3440stdout.
3441
3442Fixed up the e2fsck progress reporting functions so that the values
3443reliably reach 100% at the completion of all of the e2fsck passes.
3444
3445Fixed minor documentation bugs in man pages and usage messages.
3446
3447Programmer's notes:
3448-------------------
3449
3450Fixed a number of lint warnings in the ext2fs library and potential
3451portability problems from other OS's header files that might define
3452CPP macros for names like "max" and "min".
3453
3454ext2fs_badblocks_list_add() has been made more efficient when it needs
3455to grow the bad blocks list.
3456
3457Fixed a bug in e2fsck which caused it to dereference a freed pointer
3458just before exiting.
3459
3460Fixed the substition process for generating the mk_cmds and compile_et
3461scripts so that they will work outside of the build tree.
3462
3463Add sanity check to e2fsck so that if an internal routine
3464(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
3465and causing a core dump. This should never happen, but...
3466
Theodore Ts'oa5696711998-07-09 05:38:07 +00003467E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00003468==================================
3469
3470E2fsprogs now works with glibc (at least with the version shipped wtih
3471RedHat 5.0). The ext2fs_llseek() function should now work even with
3472i386 ELF shared libraries and if llseek() is not present. We also
3473explicitly do a configure test to see if (a) llseek is in libc, and
3474(b) if llseek is declared in the system header files. (See standard
3475complaints about libc developers don't understand the concept of
3476compatibility with previous versions of libc.)
3477
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003478The ext2fs library now writes out the block group number in each of
3479the superblock copies. This makes it easier to automatically
3480determine the starting block group of the filesystem when the block
3481group information is trashed.
3482
3483Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00003484which means that e2fsprogs will ignore the high 8 bits of the
3485directory entry's name_len field, so that it can be used for other
3486purposes.
3487
3488Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
3489E2fsprogs will now support filesystems with 64-bit sized files.
3490
3491Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
3492
Theodore Ts'o21d53851998-02-21 03:14:50 +00003493Added new program "e2label", contributed by Andries Brouwer. E2label
3494provides an easy-to-use interface to modify the filesystem label.
3495
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00003496Fixed bug so that lsattr -v works instead of producing a core dump.
3497
Theodore Ts'o21d53851998-02-21 03:14:50 +00003498Fixed a minor bug in mke2fs so that all groups with bad superblock
3499backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00003500
3501Mke2fs will check the size of the device, and if the user specifies a
3502filesystem size larger than the apparent size of the device it will
3503print a warning message and ask if the user wants to proceed.
3504
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003505E2fsck has a new option -C, which sends completion information to the
3506specified file descriptor. For the most part, this is intended for
3507programs to use, although -C 0 will print a spinning character to the
3508stdout device, which may be useful for users who want to see something
3509happening while e2fsck goes about its business.
3510
Theodore Ts'o21d53851998-02-21 03:14:50 +00003511Fixed a bug in e2fsck which could cause a core dump when it needs to
3512expand the /lost+found directory, and sometimes the bitmaps haven't
3513been merged in. Also fixed a related bug where ext2fs_write_dir_block
3514was used to write out a non-directory block. (Which would be bad on a
3515non-Intel platform with byte swapping going on.)
3516
3517Fixed bug in e2fsck where it would print a "programming error" message
3518instead of correctly identifying where a bad block was in used when
3519the bad block was in a non-primary superblock or block group
3520descriptor. Also fixed a related bug when sparse superblocks are in
3521use and there is a bad block where a superblock or block group
3522descriptor would have been in a group that doesn't include a
3523superblock.
3524
3525Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
3526the block group descriptor table is corrupt, it was possible to try to
3527allocate a huge array, fail, and then abort e2fsck.
3528ext2fs_get_num_dirs() now sanity checks the block group descriptor,
3529and subsitutes reasonable values if the descriptors are obviously bogus.
3530
3531If e2fsck finds a device file which has the immutable flag set and the
3532i_blocks beyond the normal device number are non-zero, e2fsck will
3533offer to remove it, since it's probably caused by garbage in the inode
3534table.
3535
3536When opening a filesystem, e2fsck specially checks for the EROFS error
3537code, and prints a specific error message to the user which is more
3538user friendly.
3539
3540If the filesystem revision is too high, change the e2fsck to print
3541that this is either because e2fsck is out of date, or because the
3542superblock is corrupt.
3543
3544E2fsck now checks for directories that have duplicate '.' and '..'
3545entries, and fixes this corruption.
3546
3547E2fsck no longer forces a sync of the filesystem (with attendant sleep
3548calls) at all times. The ext2fs_flush() function now performs a sync
3549only if it needed to write data blocks to disk.
3550
3551Fixed a minor bug in e2fsck's pass1b's file cloning function, where
3552certain errors would not be properly reported.
3553
3554Updated and expanded a few points in the man pages which users
3555complained wheren't explicit enough.
3556
3557Added special case byte-swapping code if compiling on the PowerPC, to
3558accomodate the strange big-endian variant of the ext2 filesystem that
3559was previously used on the PowerPC port.
3560
3561
3562Programmer's notes:
3563-------------------
3564
3565Removed C++ keywords from the ext2fs libraries so that it could be
3566compiled with C++.
3567
3568E2fsck's internal organization has now been massively reorganized so
3569that pass*.c don't have any printf statements. Instead, all problems
3570are reported through the fix_problem() abstraction interface. E2fsck
3571has also been revamped so that it can be called as a library from a
3572application.
3573
3574Added new fileio primitives in libext2fs for reading and writing
3575files on an unmounted ext2 filesystem. This interface is now used by
3576debugfs.
3577
3578Added a new libext2fs function for mapping logical block numbers of
3579a file to a physical block number.
3580
3581Added a new libext2fs function, ext2fs_alloc_block(), which allocates
3582a block, zeros it, and updates the filesystem accounting records
3583appropriately.
3584
3585Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
3586sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
3587
3588The libext2fs functions now use a set of memory allocation wrapper
3589functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
3590instead of malloc, free, and resize. This makes it easier for us to
3591be ported to strange environments where malloc, et. al. aren't
3592necessarily available.
3593
3594Change the libext2fs fucntion to return ext2-specific error codes
3595(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
3596and depending on the existence of system error codes (such as EEXIST
3597and ENOENT).
3598
3599Renamed io.h to ext2_io.h to avoid collision with other OS's header
3600files.
3601
3602Add protection against ext2_io.h and ext2fs.h being included multiple
3603times.
3604
3605The types used for memory lengths, etc. have been made more portable.
3606In generla, the code has been made 16-bit safe. Added Mark
3607Habersack's contributed DOS disk i/o routines.
3608
3609Miscellaneous portability fixes, including not depending on char's
3610being signed.
3611
3612The io_channel structure has a new element, app_data, which is
3613initialized by the ext2fs routines to contain a copy of the filesystem
3614handle.
3615
3616ext2fs_check_directory()'s callback function may now return the error
3617EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
3618really do the checking, despite the presence of the callback function.
3619
3620
Theodore Ts'obc210071997-06-17 05:41:36 +00003621E2fsprosg 1.11 (June 17, 1997)
3622==============================
3623
3624Fixed e2fsck to detect (previously ignored) conflicts between the
3625superblock or block group descriptors and block bitmaps, inode
3626bitmaps, and inode tables.
3627
3628Fixed bug in e2fsck so that when the message printed out when a block
3629or inode bitmap conflicts with other data, it has the correct group
3630number.
3631
3632Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
3633to badblocks. This meant that not all of the filesystem was being
3634tested for bad blocks!
3635
3636Fixed an array boundary overrun case which cropped up in
3637ext2fs_badblocks_list_test when a user tried running "mke2fs -c
3638-b 4096".
3639
3640Adjusted the number of columns printed by mke2fs when displaying the
3641superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00003642really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00003643
3644Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
3645dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
3646fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
3647
3648Programmer's notes:
3649-------------------
3650
3651Fixed install rule in lib/ss so that ss_err.h is actually getting
3652installed.
3653
3654Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
3655bassed back to the caller.
3656
3657Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
3658setting the current inode number (which meant this function wasn't
3659working at all).
3660
3661Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
3662blocks in the bitmap when increasing the size of the bitmap.
3663
3664Changed the initial number of blocks allocated by ext2fs_init_dblist()
3665to be more realistic.
3666
3667Added a new function ext2fs_allocate_group_table, which sets up the
3668group descriptor information (and allocates inode and block bitmaps,
3669and inode tables for a particular group). The function was created by
3670factoring out code form ext2fs_allocate_tables().
3671
3672Added a new function ext2fs_move_blocks which takes a bitmap of the
3673blocks to be moved, and moves them to another location on the
3674boardboard.
3675
3676Make the unix_io channel's io_channel_flush implementation calls sync()
3677to to flush the kernel buffers to disk.
3678
3679Added a new function ext2fs_dblist_count returns the number of
3680directory blocks in dblist.
3681
3682
Theodore Ts'oae851481997-04-29 18:13:24 +00003683E2fsprogs 1.10 (April 24, 1997)
3684===============================
3685
3686Mke2fs once again defaults to creating revision #0 filesystems, since
3687people were complaining about breaking compatibility with 1.2 kernels.
3688Warning messages were added to the mke2fs and tune2fs man pages that
3689the sparse superblock option isn't supported by most kernels yet (1.2
3690and 2.0 both don't support parse superblocks.)
3691
3692Added new flag to mke2fs, -R <raid options>, which allows the user to
3693tell mke2fs about the RAID configuration of the filesystem. Currently
3694the only supported raid option is "stride" which specifies the width
3695of the RAID stripe.
3696
3697Fixed bug in e2fsck where pass1b would bomb out if there were any
3698blocks marked bad in the inode table.
3699
3700Fixed rare bug in mke2fs where if the user had a very unlucky number
3701of blocks in a filesystem (probability less than .002) the resulting
3702filesystem would be corrupt in the last block group.
3703
3704Fixed bug where if e2fsck tried to allocate a block to fix a
3705filesystem corruption problem and the filesystem had no free blocks,
3706ext2fs_new_block() would loop forever.
3707
3708The configure script now checks explicitly to see if "-static" works,
3709since that can't be assumed to be true --- RedHat doesn't install
3710libc-static by default.
3711
3712Fixed bug in libext2's block iterator functions where under some
3713cirmcustances, file with holes would cause the bcount parameter to the
3714callback function to be incorrect. This bug didn't affect any of
3715e2fsprogs programs, but it was discovered by Paul Mackerras, the
3716author of the PPC boot loader.
3717
3718Removed use of static variables to store the inode cache in libext2fs.
3719This caused problems if more than one filesystem was accessed via
3720libext2fs (static variables in libraries are generally a bad idea).
3721Again, this didn't affect e2fsprogs programs, but it was discovered by
3722Paul Mackerras.
3723
3724Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
3725will compile cleanly with 1.2.13 kernels (even with a.out shared
3726libraries!)
3727
3728Programmer's notes:
3729-------------------
3730
3731Added new functions to duplicate an ext2 filesystem handle, and its
3732associated substructure. New functions: ext2fs_dup_handle(),
3733ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
3734Other structures, such as the io_channel and the inode_cache, now have
3735a ref count so that they only get freed when they are no longer used
3736by any filesystem handle. (These functions were added as part of the
3737development effort for an ext2 resizer).

Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00003739E2fsprogs 1.09 (April 14, 1997)
3740===============================
3741
3742Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
3743accidentally introduced in the 1.08 release. The overhead calculation
3744was accidentally removed, which caused ext2fs_initialize() to not
3745notice when the filesystem size needed to be adjusted down because
3746there wasn't enough space in the last block group.
3747
3748Fixed bug in version parsing library routine; it was always parsing
3749the library version string, instead of using the passed-in string.
3750
3751Clarified chattr man page.
3752
Theodore Ts'o24757fa1997-04-29 17:39:27 +00003753E2fsprogs 1.08 (April 10, 1997)
3754===============================
3755
3756E2fsck 1.07 was very slow when checking very large filesystems with a
3757lot of files that had hard links (i.e., news spools). This was fixed
3758by seriously revamping the icount abstraction. Added a formal test
3759suite for the icount abstraction.
3760
3761Debugfs now has a "-l" option to the "ls" command, which lists the
3762inode number, permissions, owner, group, size, and name of the files
3763in the directory.
3764
3765Fix a bug in e2fsck where when a directory had its blocks moved to
3766another location during the pass 1b processing, the directory block
3767list wasn't updated, so pass 2 wouldn't check (and correct) the
3768correct directory block.
3769
3770E2fsck will now treat inodes which contain blocks which are claimed by
3771the filesystem metadata by treating them as multiply claimed blocks.
3772This way, the data in those blocks can be copied to a new block during
3773the pass 1b--1d processing.
3774
3775E2fsck will attempt to determine the correct superblock number and
3776display it in the diagnostic and warning messages if possible.
3777
3778Add support for a new (incompatible) feature, "sparse_super". This
3779feature reduces the number of blocks which contain copies of backup
3780superblocks and block group descriptors. (It is only an incompatible
3781feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
3782support a new -s option; e2fsck will recognize filesystems built with
3783this feature turned on.
3784
3785E2fsck now checks the library to make sure is the correct version,
3786using new library functions. (This helps to diagnose incorrectly
3787installed e2fsprogs distributions.)
3788
3789Dumpe2fs now prints more information; its now prints the the
3790filesystem revision number, the filesystem sparse_super feature (if
3791present), the block ranges for each block group, and the offset from
3792the beginning of the block group.
3793
3794Mke2fs now distributes the inode and block bitmap blok so that the
3795won't be concentrated in one or two disks in RAID/striping setups.
3796Also, if the user chooses a 2k or 4k block group, mke2fs will try to
3797choose the largest blocks per group that be chosen. (For 2k blocks,
3798you can have up to 16384 blocks/group; for 4k blocks, you can have up
3799to 32768 blocks/group.) Previously mke2fs would not allow
3800specification of more than 8192 blocks per group, even if you were
3801using a 2k or 4k block group.
3802
3803Programmer's notes:
3804-------------------
3805
3806Added a new function ext2fs_create_icount2() which takes a "hint"
3807argument. This hint argument presets the icount array with the list
3808of inodes which actually need to be in the icount array. This really
3809helps to speed up e2fsck.
3810
3811Added a new function ext2fs_icount_validate() which checks the rep
3812invariant for the icount structure. This is used mostly for testing.
3813
3814The error mesasage given when a bad inode number is passed to
3815test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
3816EXT2FS_UNMARK_ERROR).
3817
3818Added a new function ext2fs_set_dir_block which sets the block of a
3819dblist entry, given the directory inode and blockcnt.
3820
3821Added a new function ext2fs_get_library_version() which returns the
3822current library version, and ext2fs_parse_version_string() which
3823returns a version number based on a e2fsprogs version string.
3824
3825The icount functions will return EINVAL if the passed in inode number
3826is out of bounds.
3827
Theodore Ts'o21c84b71997-04-29 16:15:03 +00003828E2fsprogs 1.07 (March 9, 1997)
3829==============================
3830
3831E2fsck is now uses much less memory when checking really large
3832filesystems (or rather, filesystems with a large number of inodes).
3833Previously a filesystem with 1 million inodes required 4 megabytes of
3834memory to store inode count statistics; that storage requirement has
3835now been reduced to roughly half a megabyte.
3836
3837E2fsck can now properly deal with bad blocks appearing inside the
3838inode table. Instead of trying to relocate the inode table (which
3839often failed because there wasn't enough space), the inodes in the bad
3840block are marked as in use.
3841
3842E2fsck will automatically try to use the backup superblocks if the
3843primary superblocks have a bad magic number or have missing meta-data
3844blocks (or meta-data blocks which are out of range).
3845
3846E2fsck's pass 3 has been made more efficient; most noticeable on
3847filesystems with a very large number of directories.
3848
3849Completely revamped e2fsck's system of printing problem reports. It
3850is now table driven, to make them more easily customizeable and
3851extendable. Error messages which can be printed out during preen mode
3852are now one line long.
3853
3854Fixed e2fsck's filesystem swapping code so that it won't try to swap
3855fast symbolic links or deleted files.
3856
3857Fixed e2fsck core dumping when fixing a filesystem which has no
3858directories (not even a root directory).
3859
3860Added a check to e2fsck to make sure that the length of every
3861directory entry is a multiple of 4 (since the kernel complains if it
3862isn't).
3863
3864Added a check to e2fsck to make sure that a directory entry isn't a
3865link to the root directory, since that isn't allowed.
3866
3867Added a check to e2fsk to now make sure the '.' and '..' directory
3868entries are null terminated, since the 2.0 kernel requires it.
3869
3870Added check to write_bitmaps() to make sure the superblock doesn't get
3871trashed if the inode or block bitmap is marked as being block zero.
3872
3873Added checking of the new feature set fields in the superblock, to
3874avoid dealing with new filesystem features that this package wasn't
3875set up to handle.
3876
3877Fixed a fencepost error in ext2fs_new_block() which would occasionally
3878try to allocate a block beyond the end of a filesystem.
3879
3880When the UUID library picks a random IEEE 802 address (because it
3881can't find one from a network card), it sets the multicast bit, to
3882avoid conflicting with a legitimate IEEE 802 address.
3883
3884Mke2fs now sets the root directory's owner to be the real uid of the
3885user running mke2fs. If the real uid is non-zero, it also sets
3886the group ownership of the root directory to be the real group-id of
3887the user running mke2fs.
3888
3889Mke2fs now has more intelligent error checking when it is given a
3890non-existent device.
3891
3892When badblocks is given the -vv option, it now updates the block that
3893it is currently testing on every block.
3894
3895Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
3896currently correctly if PATH wasn't already set.
3897
3898Shared libraries now built with dependencies. This allows the shared
3899library files to be used with dlopen(); it also makes the transition
3900to libc 6 easier, since ld.so can tell which libc a particular shared
3901library expects to use.
3902
3903Programmer's notes:
3904-------------------
3905
3906Added new abstraction (defined in dblist.c) for maintaining a list of
3907blocks which belongs to directories. This is used in e2fsck and other
3908programs which need to iterate over all directories.
3909
3910Added new functions which test to see if a contiguous range of blocks
3911(or inodes) are available. (ext2fs_*_bitmap_range).
3912
3913Added new function (ext2_inode_has_valid_blocks) which returns true if
3914an inode has valid blocks. (moved from e2fsck code).
3915
3916Added new function (ext2fs_allocate_tables) which allocates the
3917meta-data blocks as part of initializing a filesystem. (moved from
3918mke2fs code).
3919
3920Added a new I/O manager for testing purposes. It will either allow a
3921program to intercept I/O requests, or print debugging messages to
3922trace the activity of a program using the I/O manager.
3923
3924The badblocks_list functions now store the bad blocks in a sorted
3925order, and use a binary search to speed up badblocks_list_test.
3926
3927The inode scan function ext2fs_get_next_inode() may now return a soft
3928error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
3929those cases where part of an inode table is missing or there is a bad
3930block in the inode table.
3931
3932Added a new function (ext2fs_block_iterate2) which adds new arguments to
3933the callback function to return a pointer (block and offset) to the
3934reference of the block.
3935
3936Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
3937application to jump to a particular block group while doing an inode
3938scan.
3939
3940The badblocks list functions were renamed from badblocks_* to
3941ext2fs_badblocks_*. Backwards compatibility functions are available
3942for now, but programs should be modified to use the new interface.
3943
3944Some of the library functions were reorganized into separate files to
3945reduce the size of some programs which statically link against the
3946ext2 library.
3947
3948Put in some miscellaneous fixes for the Alpha platform.
3949
Theodore Ts'o5c576471997-04-29 15:29:49 +00003950
3951E2fsprogs 1.06 (October 7, 1996)
3952================================
3953
3954Fixed serious bug in e2fsck: if the block descriptors are bad, don't
3955smash the backup copies in ext2fs_close(). (The problem was that when
3956e2fsck -p discovered the problem, while it was closing the filesystem
3957and exiting, it was also blowing away the backup superblocks on the
3958disk, which was less than friendly.) We now make it the case that we
3959only write out the backup superblock and the back block descriptors if
3960the filesystem is completely free from problems.
3961
3962Fixed a bug in block_interate in the lib/ext2fs library which caused
3963e2fsck to fail on GNU Hurd-created filesystems.
3964
3965Add support for Linux/FT's bootloader, which actually uses
3966EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
3967to clear the inode.
3968
3969Add support for the "A" (no atime update) attribute. (Note: this
3970attribute is not yet in production kernels.)
3971
3972The test suite is not automatically run when doing a "make all" from
3973the top level directory. Users should manually run "make check" if
3974they wish to run the test suite.
3975
3976Upon a preenhalt(), make the printed message more explicit that
3977running e2fsck "MANAULLY" means without the -p or -a options.
3978
3979In e2fsck, if a disconnected inode is zero-length, offer to clear it
3980instead of offering to connect it to lost+found.
3981
3982In e2fsck, if a filesystem was just unmounted uncleanly, and needs
3983e2fsck to be run over it, change e2fsck to explicitly display this
3984fact.
3985
3986For dumpe2fs and e2fsck, cause the -V option to print out which
3987version of the ext2fs library is actually getting used. (This will
3988help detect mismatches of using a 1.06 utility with a 1.05 library,
3989etc.)
3990
3991Programmers' notes:
3992-------------------
3993
3994EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
3995the naming convention.
3996
3997In ext2fs_initialize(), make sure the description for the inode bitmap
3998is correctly initialize.
3999
4000Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4001
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00004002E2fsprogs 1.05 (September 7, 1996)
4003==================================
4004
4005Add support for new fields in the ext2 superblock --- volume name,
4006volume UUID, and last mounted field. Dumpe2fs displays these fields,
4007tune2fs and mke2fs allows you to set them. E2fsck will automatically
4008generate a UUID for those volumes that don't have them.
4009
4010Put in support for e2fsck to recognize HURD specific ext2 features ---
4011most notably, the translator block. The e2fsprogs tools will now use
4012the creator_os field in the superblock to correctly handle different
4013OS-specific variants of the ext2 filesystem.
4014
4015E2fsck now fixes inodes which have a the deletion time set, but which
4016have a non-zero i_link_count field by offering to clear the deletion
4017time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4018ext2 kernel behavior) and offered to unlink the file.
4019
4020If e2fsck sets the clean bit, but nothing else, set the exit code
4021FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4022set the filesystem valid bit when it was previously cleared. :-) This
4023was needed to make the HURD fsck driver happy.
4024
4025If the user refuses to attach an unattached inode, e2fsck will no
4026longer set the inode's link count. Otherwise, the inode would end up
4027getting marked as unused, which might cause loss of data later.
4028
4029Make the message issued by e2fsck when the superblock is corrupt less
4030confusing for users. It now mentions that another reason for the
4031"corrupt superblock" message might be that the partition might not be
4032an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4033
4034Make the libext2 library more robuest so that e2fsck won't coredump on
4035an illegal superblock where the blocksize is zero. (f_crashdisk is
4036the test case).
4037
4038By default, create filesystems where the default checkinterval is 6
4039months (180 days). Linux servers can be robust enough that 20 reboots
4040can be a long, long time.
4041
4042Added configure flag --enable-old-bitops, which forces the bitops to
4043use the old (native) bitmask operations. By default on the sparc
4044platform, the standard ext2 bit ordering is now used.
4045
4046Added a new feature to e2fsck to byte-swap filesystems; this can be
4047used to convert old m68k filesystems to use the standard byte-order
4048storage for the superblock, inodes, and directory blocks. This
4049function is invoked by using the '-s' option to e2fsck.
4050
4051Debugfs's "dump" command has been enhanced so that it writes out the
4052exact size of the file so that the nulls at the end of the file are
4053eliminated. The command also accept a new "-p" option which will
4054attempt preserve to preserve the ownernship, permissions, and
4055file modification/access times.
4056
4057Debugfs has two new options, -f and -R. The -R option allows the user
4058to execute a single debugfs command from the command line. The -f
4059option allows the user to specify a "command file" containing debugfs
4060commands which will get executed.
4061
4062Dumpe2fs now pretty prints the check interval, instead of just
4063printing the check interval as a number of seconds.
4064
4065Fix bugs in debugfs: the params command when no filesystem is opened
4066no longer causes a core dump. It is now possible to unlink a file
4067when a pathame containing a '/' is specified.
4068
4069Tune2fs has a new -C option which sets the number of times the
4070filesystem has been mounted.
4071
4072Fix the chattr '-v' option so that it actually works. Chattr was
4073being buggy about the -v option parsing.
4074
4075Programmers' notes:
4076-------------------
4077
4078The directory lib/uuid contains a set of library routines to generate
4079DCE compatible UUIDs.
4080
4081Extended ext2fs_namei() to handle symbolic links. Added new function
4082ext2fs_nami_follow() which will follow last symbolic link in the case
4083where the pathname points to a sym link.
4084
4085The ext2fs_block_iterate function will now return the HURD translator
4086block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4087iterator to return data blocks only. The ext2fs.h file now defines
4088constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4089BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4090count field of the iterator callback function.
4091
4092The test script driver now takes an optional second argument, which is
4093the test case to be run. This allows you to run a test case without
4094needing to run the entire test suite.
4095
4096On Linux ELF systems, install the .so files in the correct places
4097(/usr/lib). The .so files must be stored in the same directory as the
4098.a files.
4099
4100Fixed miscellaneous HURD compilation issues with header file being
4101included in the right order.
4102
4103Fixed debugfs so that it resets optind to zero, not one, since setting
4104optind to zero is more correct.
4105
4106
Theodore Ts'oa4d09611997-04-29 14:28:00 +00004107E2fsprogs 1.04 (May 16, 1996)
4108=============================
4109
4110First "official" (1.03 was a limited release only) to support building
4111e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4112kernels).
4113
4114This package includes a RPM specs file, that it can be built using the
4115RedHat Package Manager.
4116
4117E2fsck now prints a hint that if there are lots of incorrectly located
4118inode bitmaps, block bitmaps, and inode table blocks, the user might
4119want to try using e2fsck -b 8193 first, to see if that fares any
4120better.
4121
4122For ext2 filesystem written with the hurd, debugfs will now print out
4123the translator field when printing an inode structure.
4124
4125Lots of miscellaneous linking/installation cleanups:
4126
4127 Libraries are now linked using a relative pathname, instead of
4128 relying on -L working correct. It doesn't, in many cases, including
4129 current versions of GNU ld. This guarantees that the build tree is
4130 linking with the right libraries, instead of the ones installed in
4131 /usr/lib.
4132
4133 Header files, man pages, and the et/ss shell scripts are now
4134 generated using a custom substitution script, instead of relying on
4135 the configure script. This prevents needless recompilation of
4136 files; in addition, the custom substitution script is much faster.
4137
4138 e2fsck may now be linked dynamically, by using the
4139 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4140 since it increases e2fsck's dependence on other files, but some
4141 people need to save disk space, and other critical programs on their
4142 systems were being linked dynamically anyway.
4143
4144 Programs such as fsck which didn't need to be linked against
4145 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4146 only link against libraries they actually need. Otherwise, those
4147 programs would require the presense of libraries that otherwise
4148 could be removed from a rescuse diskette.
4149
4150 The ss include files are now installed correctly so they can
4151 actually be used by another package.
4152
4153 If the profiling libraries are built, they are now installed on a
4154 "make install-libs".
4155
4156
Theodore Ts'o7f88b041997-04-26 14:48:50 +00004157E2fsprogs 1.03 (March 27, 1996)
4158===============================
4159
4160Change the m68k bit numbering for bitmasks to match the bit numbering
4161used by all other ext2 implementations. (This change was requested by
4162the m68k kernel development team.)
4163
4164Support (in-development) filesystem format revision which supports
4165(among other things) dynamically sized inodes.
4166
4167Fixed a bug in the ext2 library so that an intelligent error is
4168returned if mke2fs is run with a ridiculously small number of blocks
4169for a partition.
4170
4171Fixed a bug in the ext2 library which required that the device be
4172openable in read/write mode in order to determine its size. This
4173caused e2fsck -n to require read/write access when it was not
4174previously necessary.
4175
4176Fixed a bug in e2fsck which casued it to occasionally fail the test
4177suite depending on which version of the floating point library it was
4178using.
4179
4180Fixed a bug in e2fsck so that it now halts with a fatal error when
4181certain superblock consistency checks fail. Previously it continued
4182running e2fsck, with some potential confusing/damaging consequences.
4183
4184Added new flag to fsck which allows the root to be checked in parallel
4185with other filesytems. This is not the safest thing in the world to

4191E2fsprogs 1.02 (January 16, 1996)
4192=================================
4193
4194Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4195
4196Change e2fsck to print statistics of how many non-contiguous files are
4197on the system. Note that a file which is larger than 8k blocks, it is
4198guaranteed to be non-contiguous.
4199
4200In mke2fs, print a warning message if a user tries to format a whole
4201disk (/dev/hda versus /dev/hda1). If a user really wants to format a
4202whole disk, the -F (force) option forces mke2fs to format a whole disk
4203as a filesytem.
4204
4205Fix a bug in fsck where in some cases it might start checking
4206partitions in the next pass before it finishes checking partitions in
4207the current pass. This still won't cause two partitions on the same
4208disk will be checked, so it's rarely a problem in real life.
4209
4210Patch lsattr so that it won't hang when checking a named pipe.
4211
4212Minor compilation fixes:
4213 * Fix the order of libraries that were linked in debugfs.
4214 * Allow the sources to be compiled with -ansi turned on.
