Theodore Ts'o24a24cc2009-07-09 08:09:58 -04001E2fsprogs 1.41.8-WIP (July 7, 2009) commit: 4bd87f22
2===================================
3
4Fix resize2fs's online resizing, fixing a regression which in
5e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
6
7Fix potential filesystem corruptions caused by using resize2fs to
Theodore Ts'o989a01f2009-07-11 18:29:56 -04008shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
9Bug: #510379)
Theodore Ts'o24a24cc2009-07-09 08:09:58 -040010
11Optimize uuid_generate() to avoid running uuidd if it is not setuid or
12setgid and the currently running program doesn't have write access to
13the uuidd work directory.
14
15Add safety checks (for non-Linux systems) so that uuidd isn't run with
16file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
17will be careful not to close the file descriptor for its unix domain
18socket when it detaches itself from the controlling tty. Also add
19safety checks so that if the unix domain socket between the uuid
20library and uuidd program is closed for any reason, both the library
21and the uuidd will return an appropriate error code instead of looping
22in an infinite loop.
23
24The e2croncheck script, which creates an LVM snapshot and then checks
25the ext3/4 filesystem via the LVM snapshot, has been added to the
26contrib directory.
27
28Fix filefrag program for files that have more than 144 extents.
29
Theodore Ts'o989a01f2009-07-11 18:29:56 -040030Update French, Polish, Czech, Indonsian, and Sweedish translation from
31the Translation Project.
32
33Fixed various Debian packaging issues --- see debian/changelog for
34details. (Addresses Debian Bug #535530)
Theodore Ts'o24a24cc2009-07-09 08:09:58 -040035
36Update/clarify man pages.

38Programmer's Notes
39------------------
40
41Fix compilation problem when configured with --disable-uuid.
42
43Don't build uuidgen if configured with --disable-uuid.
44
Theodore Ts'o989a01f2009-07-11 18:29:56 -040045Add the new library function ext2fs_test_inode_bitmap_range(), and
46optimized ext2fs_test_block_bitmap_range(), which will be needed for
47future optimizations for e2fsck.
48
Theodore Ts'o24a24cc2009-07-09 08:09:58 -040049Fix makefile dependencies for libcom_err so that the Makefiles work
50well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
51
52Enhance the build system so that the full set of commands executed by
53the Makefiles are displayed, instead of the Linux kernel summary
54output, if the build was configured with --enable-verbose-makecmds, or
55if GNU make is in use and the V variable is non-null, i.e., via "make
56V=1".

60================================
61
62Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
63uninitalized data into the portion of the inode beyond the first 128
64bytes when operating on inodes mapped via extents; potentially
65corrupting filesystems.
66
67Fix memory leaks in e2fsprogs, including a very large memory leak
68which can cause e2fsck to run out of memory when checking very large
69filesystems using extents.
70
71The logsave program will now filter out the ^A and ^B characters when
72writing to the console.
73
74Harden ext2fs_validate_entry() so that lsdel will not read beyond the
75end of the block even if the directory block is corrupted.
76
77Fix debugfs from core dumping if the logdump command fails to open the
78output file.
79
80Enhance badblocks to print the currently tested block number when
81interrupted with ^C.
82
83Fix lsattr to exit with a non-zero status when it encounters errors.
84(Addresses RedHat Bugzilla #489841)
85
86Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
87filesystems as the kernel when encoding rec_len >= 64k. For 64k
88filesystems (currently all that is supported by e2fsprogs, this is
89only a minor corner case).
90
91Resize2fs will now update the journal backup fileds in the sup0erblock
92if the journal is moved; this avoids an unnecessary full fsck after
93resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
94
95Fix libext2fs to properly initialize i_extra_size when creating the
96journal and resize inodes.
97
98Change badblocks to allow block sizes larger than 4k.
99
100Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
101
102Update Chinese and Czech translation from the Translation Project.
103
104Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
105
106
107Programmer's Notes
108------------------
109
110Add --disable-libuuid option to configure which uses an in-system
111installed version of libuuid; the private version is enabled by
112default.
113
114Add --valgrind-leakcheck option to the test_script program which runs
115valgrind with the appropriate options to find memory leaks.

Theodore Ts'od17ad122009-05-30 13:56:31 -0400118E2fsprogs 1.41.6 (May 30, 2009)
119===============================
120
121Fix a critical regression in e2fsck introduced version 1.41.5 which
122can undo updates to the block group descriptors after a journal replay.
123
124If e2fsck receives an I/O error while replaying the journal, prompt
125the user whether they want to ignore the error or not; if e2fsck is
126run in preen mode, force fsck to abort the preen pass.
127
128Fix a bug which would cause e2fsck to core dump if the filesystem
129contains a corrupt extent header, and the user declines to clear the
130inode. (Addresses Sourceforge Bug: #2791794)
131
132Fix e2fsck to restart only once in the case of multiple block groups
133which inodes in use that are in the uninitialized part of the block
134group's inode table.
135
136To reduce user confusion, if the /etc/mtab file is missing
137ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
138new, explicit error code to indicate this case. This will cause
139e2fsck to give a clearer error message when the user is using buggy
140rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
141Bug: #527859)
142
143Fix e2fsck so that if the primary group descriptors are corrupted, but
144the backup superblock is entirely invalid, to go back to using (and
145fixing) the priary group descriptors instead of completely giving up
146on the filesystem. (Addresses Debian Bug: #516820)
147
148Change e2fsck to not abort a preen pass if an inode is found to have
149i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
150kernels (post 2.6.29) will ignore this field. So let's fix it
151automatically during the preen pass instead of forcing the user to fix
152this up manually. (Addresses Debian Bug: #526524)
153
154Add resource tracking for e2fsck passes 1b through 1d.
155
156Speed up e2fsck by eliminating unnecessary journal checks if the
157filesystem is already mounted and doesn't need recovery (since the
158kernel would have run the journal when the filesystem was mounted.)
159Also speed up e2fsck by avoiding unnecessary block group descriptor
160updates in ext2fs_close().
161
162Add support to chattr to migrate inodes from using direct/indirect
163blocks to extents.
164
165Avoid corrupting the filesystem if there is an attempt to shrink a
166filesystem using resize2fs smaller than posible by making
167ext2fs_set_bmap() more careful not to delete the old block until the
168new block can be inserted. In addition, fix a bug in how the minimum
169size of the filesystem (plus a safety margin) is calculated, and
170modify resize2fs to refuse to shrink the filesystem below that minimum
171size without the force flag.
172
173Teach blkid to try to figure out DM device names using take advantage
174of information in sysfs when running on kernels (2.6.29 and later)
175which provide this information in /sys/block/dm-<N>/dm/name; this is
176much faster than scanning for the devncie number in /dev/mapper.
177
178Fix blkid to prefer /dev/mapper/<name> device names instad of the
179private /dev/dm-X names.
180
181Add an -a option to debugfs's close_filesys command which writes any
182changes to the superblock or block group descriptors to all of the
183backup superblock locations.
184
185Add support to the filefrag program to use the FIEMAP ioctl.
186
187Update Chinese translation from the Translation Project.
188
189Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
190Launchpad Bug: #381854)
191
192Fixed various Debian packaging issues --- see debian/changelog for
193details. (Addresses Debian Bug #506064)
194
195
196Programmer's Notes
197------------------
198
199Add test code to make sure e2fsck's problem.c doesn't have two problem
200codes assigned to duplicate values.
201
202Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
203(Addresses Sourceforge Bug: #2780205)
204
205Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
206function declaration for init_resource_track() and
207print_resource_track() when RESOURCE_TRACK is not defined.
208
209The test code which is used to build the tst_csum progam has been
210moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
211avoid compile problems caused by not having a prototype for
212ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
213
214Update the config.guess and config.sub file to the latest from the
215FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
216Debian Bug: #528330)
217
218Add a new function, ext2fs_extent_open2(), which behaves like
219pext2fs_extent_open(), but uses the user-supplied inode structure
220when opening an extent instead of reading the inode from disk.
221
222
Theodore Ts'o898ddb02009-04-23 22:44:16 -0400223E2fsprogs 1.41.5 (April 23, 2009)
224=================================
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400225
226Fix a number of filesystem corruption bugs in resize2fs when growing
227or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
228is not mounted).
229
230Debugfs can now set i_file_acl_high via the set_inodes_field command,
231and print a 64-bit file acl. This is useful for debugging filesystem
Theodore Ts'o898ddb02009-04-23 22:44:16 -0400232corruptions where the high bits of i_file_acl_high are set. E2fsck
233will detect and fix non-zero i_file_acl_high on 32-bit filesystems
234since some Linux kernel versions pay attention to this field even when
235they shouldn't.
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400236
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400237Speed up e2fsck when checking clean filesystems by avoiding
238unnecessary block reads, and coalescing the block group descriptor
239blocks so they are read using a single read operation.
240
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400241The libuuid library will now close all file descriptors before running
242uuidd. This avoids problems when the calling program has open sockets
243which then never get closed because uuidd is a long-running helper
244daeomn. (Addresses Launchpad bug: #305057)
245
246In order to avoid unnecessary full filesystem checks by e2fsck after
247an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
248the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
249
250Mke2fs will avoid trying to create the journal when run in
251superblock-only mode (mke2fs -S), since the left-over journal in the
252inode table will cause mke2fs to fail.
253
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400254Fix a bug in libext2fs functions that check to see if a particular
255device or filesystem image is mounted, which would cause these
256functions to report that a file identical to the (relative) pathname
257used by a pseudo-filesystem was mounted when in fact it was not.
258
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400259Update Czech translation from the Translation Project.
260
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400261Add Chinese (simplified) translation from the Translation Project.
262
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400263Fix support for external journals (which was broken in e2fsprogs
2641.41.4).
265
266Fix a regression in debugfs where the "stat" command when no
267filesystem was open would cause debugfs to crash with a segmentation
268violation.
269
270Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
271used to support filesystems without a journal. Update the blkid
272library so it understands this.
273
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400274The blkid library will remove an entry from the blkid cache
275representing the entire disk if partitions are found, since presuambly
276the device previously had no partition table, but has now transitioned
277to using a partition table.
278
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400279Add a check to mke2fs and tune2fs that the argument to the -m option
280(which specifies the reserved ratio) must be greater than zero.
281(Addresses Debian Bug: #517015)
282
283Add support for tracking the number kilobytes written to the
284filesystem via the superblock field s_kbytes_written. It will be
285updated by the kernel as well as by e2fsprogs programs which write to
286the filesystem. This is useful for tracking the wear to filesystems
287on Solid Sstate Drives.
288
289Fix compatibility issue in the libext2fs info file and makeinfo
290version 4.12. (Addresses Red Hat Bugzilla: #481620)
291
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400292Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400293

301Bug: #521602)
302
303Fix various gcc compilation warnings and other programming cleanups.
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400304(Addresses Red Hat Bugzilla: #486997)
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400305
306Add support for building the blkid command statically.
307
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400308Add support for disabling the built-in blkid library in favor of a
309system-installed blkid implementation via the configure option
310--disable-libblkid.
311

Theodore Ts'ob2ca48f2009-01-27 19:51:00 -0500313E2fsprogs 1.41.4 (January 27, 2009)
314===================================
315
316Fixed a bug which could sometimes cause blkid to return an exit value
317of zero for a non-existent device (Addresses Debian Bug: #502541)
318
319Blkid will now recognize ext3 filesystems that have the test_fs flag
320set as ext3 filesystems.
321
322The blkid library will now recognize btrfs filesystems and swap
323devices currently used by user-level software suspend.
324
325Tune2fs now updates the block group checksums when changing the UUID
326to avoid causing e2fsck to complain vociferously at the next reboot.
327
328Tune2fs's inode size resizing algorithms have been fixed so it is not
329vastly inefficient for moderate-to-large filesystems, due to some
330O(n**2) and O(n*m) algorithms that didn't scale well at all.
331
332Fix tune2fs's inode resizing algorithm so it will not corrupt
333filesystems laid out for RAID filesystems; in addition, tune2fs will
334refuse to change the inode size for filesystems that have the flex_bg
335feature enabled. (This is a limitation in the current implementation
336of tune2fs -I.)
337
338E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
339filesystems with 32-bit block numbers, when the headers for 64-bit
340block numbers was added. This regression has been fixed.
341
342Debugfs's ncheck command has been fixed to avoid printing garbage
343characters at the end of file names.
344
345Fix resize2fs for ext4 filesystems. Some blocks that that need moving
346when shrinking filesystems with uninit_bg feature would not be moved.
347In addition, blocks and inode table blocks were not being correctly
348freed when shrinking filesystems with the flex_bg feable, which caused
349resize2fs -M to fail. Finally, when blocks are moved, make sure the
350uninitialized flag in extents is preserved.
351
352Fix bug which caused dumpe2fs to abort with an error if run on a
353filesystem that contained an external journal.
354
355Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
356for this in argv[0] to provide better legacy support for these
357distributions. This is a practice that should NOT be continued,
358however.
359
360Mke2fs now has a new option -U, which allows the user to specify the
361UUID that should be used for the new filesystem.
362
363Mke2fs will treat devices that are exactly 16TB as if they were 16TB
364minus one block. This allows users who have read that ext3 supports
365up to 16TB filesystems and who create a 16TB LVM to not get confused,
366since the true limit is really 16TB minus one block.
367
368E2fsck will no longer abort an fsck run if block group has an errant
369INODE_UNINIT flag.
370
371E2fsck now distinguishes between fragmented directories and fragmented
372files in verbose mode statistics and in the fragcheck report.
373
374Fix a bug in e2fsck which casued it double count non-contiguous
375extent-based inodes.
376
377E2fsck will leave some slack space when repacking directories to allow
378room for a few directory entries to be added without causing leaf
379nodes to be split right away.
380
381Fix a bug which caused e2fsck to crash when it comes across a
382corrupted interior node in an extent tree with the error message:
383"Error1: Corrupt extent header on inode XXXXXX"
384
385E2fsck problem descriptions involving the journal are no longer
386referred to as "ext3" problems, since ext4 filesystems also have
387journals.
388
389Fix a long-standing bug in e2fsck which would cause it to crash when
390replying journals for filesystems with block sizes greater than 8k.
391
392Update Catalan translation from the Translation Project.
393
394Fixed various Debian packaging issues --- see debian/changelog for
395details. (Addresses Debian Bugs: #503057, #502323, #511207)
396
397Programmer's Notes
398------------------
399
400Fix build of e2fsck.profiled, and add support for building profiled
401binaries in the misc directory if configured with --enable-profile.
402
403The ext2fs_open() function now performs more sanity checks on the
404superblock to avoid potential divide by zero errors by other parts of
405library.
406
407The ext2fs_read_inode_full() function now has a safety check to avoid
408a segmentation fault on corrupted filesystems.
409
410The ext2fs_new_inode() function now has a sanity check so that if the
411s_first_inode field in the superblock is insane, it will return
412EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
413
414To avoid segmentation faults, ext2fs_block_alloc_stats() and
415ext2fs_inode_alloc_stats() now validates the passed inode or block
416number to avoid overrunning an array boundary.
417
418Various signed/unsigned errors for variables containing block numbers
419have been fixed.
420
421Accomodations for gcc's stupidity in not realizing that constant
422strings that do not contain a '%' character are safe to use in format
423strings have been made so that distributions that want to compile
424e2fsprogs with -Werror=format-security have an easier time doing so.
425
426Added a new 64-bit getsize interface, ext2fs_get_device_size2().
427
428Added the utility make-sparse.c to the contrib directory.
429
430The ext2fs_block_iterate2() function now reflects errors from
431ext2fs_extent_set_bmap() to the caller, if the callback tries to
432change a block on an extent-based file, and ext2fs_extent_set_bmap()
433fails for some reason (for example, there isn't enough disk space to
434split a node and expand the extent tree.
435
436The ext2fs_block_iterate2() function will preserve the uninit flag in
437extents when the callback function modifies a block in an extent-based
438file.
439
440E2fsck will now flag filesystems that have an insane s_first_ino field
441in their superblock, and attempt to use a backup superblock to repair
442the filesystem.

446===================================
447
448E2fsck has been fixed so it prints the correct inode number for
449uinit_bg related problems.
450
451E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
452is available on linux. This can be disabled via a configuration
453option in /etc/e2fsck.conf.
454
455Fix a file descriptor leak in libblkid when checking to see if an ext4
456or ext4dev module exists.
457
458Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
459while trying to close a filesystem can lead to infinite loops.

Theodore Ts'oc12125f2008-10-01 23:16:06 -0400487E2fsprogs 1.41.2 (October 2, 2008)
488==================================
489
490Fix e2fsck's automatic blocksize detection. This fixes a regression
491from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
492specifies a block number using the -b option if the blocksize option
493isn't also specified using -B. Unfortunately, users very commonly
494invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
495superblock; in fack e2fsck will often suggest this kind of command
496line. Oops.
497
498Enhance the debugfs's "ncheck" command so it will print all of the
499pathnames for the specified inodes. (Previously, in some cases ncheck
500might not print a pathname for an inode at all if some of the other
501inodes had multiple hard links.)
502
503Enhance debugfs's "hash" command so the hash seed can be specified via
504a command-line option. In addition, allow the hash algorithm to be
505specified by name instead of just by number.
506
507Fix e2fsck so that we don't accidentally print the translation file's
508header when asking the user a custom question so there is no prompt
509defined for a particular problem record. For example, the question
510"Run journal anyway" will get the PO header tacked on because e2fsck
511erroneously passed the null string to _(). (Addresses Launchpad Bug:
512#246892)
513
514Enhance badblocks so that it can test a normal file which is greater
515than 2GB.
516
517Enhance the badblocks command so that it displays the time and
518percentage complete when in verbose mode. (Addresses Debian Bug:
519#429739)
520
521Fix a potential memory leak in a error handling path in debugfs's
522ncheck function.
523
524Fix a potential memory corruption problem if a memory allocation fails
525in resize2fs.
526
527Fix the usage message for debugfs's logdump command to be consistent
528with its man manpage.
529
530Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
531and Sweedish translation from the Translation Project.
532
533Add documentation for the file I/O functions to the libext2fs.texinfo
534file. (Addresses Debian Bug: #484877)

542Programmer's Notes
543------------------
544
545Fix a potential file descriptor leack in libcom_err by setting the
546close-on-exec flag for a fd used for debugging. (Addresses Red Hat
547Bugzilla #464689)
548
549Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
550has been carrying a patch for a long time to prevent a largely
551theoretical race condition if a multi-threaded application adds and
552removes error tables in multiple threads. Unfortunately SuSE's
553approach breaks compatibility by forcing applications to link and
554compile with the -pthread option; using pthread mutexes has
555historically been problematic. We fix this by using sem_post/sem_init
556instead.
557
558Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
559Sourceforge Bug: #2087502)
560
561Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
562libraries when using ELF shared libraries.
563
564Fix ELF shared library when building on systems that don't already
565have the e2fsprogs shared libraries already installed. (Addresses
566Sourceforge Bug: #2088537)
567
568Fix the pkg-config files so they work correctly when linking with
569static libraries and fix the include directory so programs don't have
570to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
571instead. (Addresses Sourceforge Bug: #2089537)
572
573Make sure ext2fs_swab64() is compiled for all platforms, and not just
574for x86. (Addresses Debian Bug: #497515)
575
576Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
577non-x86 platforms. (They had been removed for x86 earlier.)
578
579Fix diet libc compilation support, which had bitrotted due to lack of
580TLC. Fixing this improves general portability.
581
582When installing the link library when using ELF shared libraries,
583avoid using absolute pathnames if the link library and the shared
584library are installed in the same directory. (Addresses Sourceforge
585Bug: #1782913)
586
587Fix gen-tarball so it will work even if the top-level directory has
588been renamed to something other than "e2fsprogs". Also make
589gen-tarball print the size of the resulting tar.gz file.

Theodore Ts'o31d64872008-09-01 10:39:35 -0400592E2fsprogs 1.41.1 (September 1, 2008)
593====================================
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400594
595Many people are forgetting to update their mke2fs.conf file, and this
596causes ext3, ext4, and ext4dev filesystems won't get created with the
597proper features enabled. We address this in two ways. First, mke2fs
598will issue a warning if there is not definition for an ext3, ext4, or
599ext4dev filesystem and the user is trying to create such a filesystem
600type. Secondly, when installing from a source build, "make install"
601will provide basic configuration file handling for /etc/mke2fs.conf.
602If it exists, and does not mention ext4dev, it will be moved aside to
603/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
604be installed. If the existing /etc/mke2fs.conf file does mention
605ext4dev, then "make install" will install official mke2fs.conf file as
606/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
607they should look to see if any changes need to be merged.
608
Theodore Ts'o31d64872008-09-01 10:39:35 -0400609The mke2fs program will now create the journal in the middle of the
610filesystem, since this minimizes seek times on average for fsync-heavy
611workloads. In addition, mke2fs will now create journals using extents
612for filesystems that support them. This results in a more efficient
613encoding for the journal since it eliminates the need for using
614indirect blocks.
615
616The mke2fs program will avoid allocating an extra block to the
617journal. (Addresses Sourceforge Bug: #1483791)
618
619Mke2fs will correctly enforce the prohibition against features
620(specifically read-only features) in revision 0 filesystems. (Thanks
621to Benno Schulenberg for noticing this problem.)
622
623Mke2fs previously would occasionaly create some slightly non-optimally
624placed inode tables; this bug has been fixed.
625
626The mke2fs and tune2fs programs now print the correct usage message
627describing the maximum journal size. (Addresses Debian Bug: #491620)
628
629Add support for setting the default hash algorithm used in b-tree
630directories in tune2fs (from a command-line option) or mke2fs (via
631mke2fs.conf). In addition, change the default hash algorithm to
632half_md4, since it is faster and better.
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400633
634The blkid library will now recognize MacOS hfsx filesystems, and
635correctly extract the label and uuid for hfs, hfsx, and hfsplus
636filesystems. (Addresses Sourceforge Feature Requests: #2060292)
637
Theodore Ts'o31d64872008-09-01 10:39:35 -0400638The blkid library has improved detection of JFS and HPFS filesystems.
639(Addresses Launchpad Bug: #255255)
640
641The blkid library is now much more efficiently handling devicemapper
642devices, mainly by no longer using the devicemapper library. This can
643speed up access for systems with a large number of device mapper
644devices.
645
646Blkid had a number of cache validation bugs in libblkid that have been
647fixed. (Addresses Debian Bug: #493216)
648
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400649Resize2fs will now properly close out the "updating inode references"
650progress bar so there is a newline printed before printing the final
651"resize is successful" message.
652
653Resize2fs will now correctly handle filesystems with extents and/o
654uninitialized block groups correctly when file/directory blocks need
655to relocated (i.e., when shrinking a filesystem or if the resize_inode
656is not present). To support this, the ext2fs library now supports
657initializing inode and block bitmaps that are not yet initialized when
658allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
659addition, e2fs_block_iterate2() can now support changing the location
660of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
661been optimized to avoid creating unnecessary new extents when updating
662the location of blocks in the extent tree. This will also help out
663e2fsck's recovery of obscurely corrupted filesystems with extents,
664when blocks are claimed by multiple inodes.
665
Theodore Ts'o31d64872008-09-01 10:39:35 -0400666Add support for on-line resizing ext4 filesystem with the flex_bg
667filesystem feature. The method for doing so is not optimal, but to do
668a better job will require kernel support.
669
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400670E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
671debugfs programs to not be able to read e2image files; the signed
672vs. unsigned bug in the code which read bitmaps from the e2image has
673been fixed. (Addresses Debian Bug: #495830)
674
675Resize2fs is now correctly managing the directory in-use counts when
676shrinking filesystems and directory inodes needed to be moved from one
677block group to another. This bug has been around since e2fsprogs
6781.26, and is largely harmless, but does cause a filesystem corruption
679which will be flagged by e2fsck after the filesystem has been shrunk.
680
681E2fsck will no longer issue spurious complaints about the inode size
682caused by very large extent-based files, and by blocks reallocated
683using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
684Kernel Bugzilla: #11341)
685
686Mke2fs will now set the creation timestamp on the lost+found directory
687and the root directory. (More generally, all new inodes created using
688the ext2fs library will correctly set the creation timestamp.)
689
690E2fsck now correctly calculates ind/dind/tind statistics in the
691presence of extent-based files. In addition, "e2fsck -v" will report
692statistics of the depth of extent trees in the filesystem. E2fsck can
693also give an inode fragmentation report using "e2fsck -E fragcheck"
694which can be useful when debugging the kernel block allocation
695routines.
696
Theodore Ts'o31d64872008-09-01 10:39:35 -0400697Fix support for empty directory blocks in ext4 filesystems with 64k
698blocksize filesystems.
699
700E2fsck will now print the depth of corrupt htree directories.
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400701
702Debugfs's htree command now correctly understands extent-based
703directories. It will also print out the minor hash as well as the
704major hash.
705
Theodore Ts'o31d64872008-09-01 10:39:35 -0400706Debugfs has a new command which will print the supported features of
707e2fsprogs, to enable scripts to know whether the installed version of
708e2fsprogs can support a specific feature.
709
710Debugfs will now write files using extents for filesystems that
711support them.
712
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400713The error message printed by "tune2fs -I" if the inode size was too
714small was rather confusing, so it has been improved. Also, we won't
715try to create an undo log until we know that command-line-specified
716parameters such as "tune2fs -I <inode size>" are valid.
717
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400718Given some filesystems found "in the wild" that had non-zero block
719group checksums even though the uninit_bg/gdt_sum feature was not
720enabled, e2fsck would issue spurious error messages. Teach
721ext2fs_group_desc_csum_verify() to ignore the block group checksum
722entirely if the feature flag is not set. (Addresses Debian Bug:
723#490637)
724
725The blkid program will now print out a user-friendly listing of all of
726the block devices in the system and what they contain when given the
727-L option. (Addresses Debian Bug: #490527)
728
Theodore Ts'o31d64872008-09-01 10:39:35 -0400729The filefrag program now has a more accurate calculation for the
730number of ideal extents. (Addresses Debian Bug: #458306)
731
732The test I/O manager is now enabled by default, but its overhead is
733only incurred when it would be enabled via the TEST_IO_FLAGS or
734TEST_IO_BLOCK environment variables.
735
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400736Typographical errors in various program strings and usage messages
737have been fixed; most of these were pointed out by the e2fsprogs
738message catalog translators. (Thanks, translators!)
739
740Update and clarified various man pages, as well as some typographical
741errors in the libext2fs texinfo file.
742
743Fixed various Debian packaging issues --- see debian/changelog for
744details.
745
746Add Indonesian and update French, Polish, Dutch, German, Sweedish,
747Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
748#401092)
749
750Programmer's Notes
751------------------
752
753Fix portability problem with the badblocks group; for systems that
754don't have nanosleep(), try using usleep() instead.
755
756The "make check" target in the e2fsck directory now sets
757LD_LIBRARY_PATH before running the various e2fsck internal library
758regression tests.
759
760The crc32 regression test in the e2fsck library is now portable to
761greater varienty of environments, including big-endian systems and
762when cross-building e2fsprogs for embedded systems. (Addresses
763Sourceforge Bug: #2019287)
764
765The ext2fs_extent_set_bmap() had some bugs when setting the first
766block in a file, or when replacing a single block extent. Those cases
767fortunately were came up relatively rarely when e2fsck was checking
768files, but caused some problems when resize2fs was shrinking
769extent-based files.
770
Theodore Ts'o31d64872008-09-01 10:39:35 -0400771Fix a potential core-dumping bug in libe2p's iterate_on_dir()
772function.
773
774Various ext2fs library functions --- ext2fs_block_iterate2(),
775ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
776allocated memory to avoid memory leaks in all of their error return
777paths.
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400778
779Ext2ed was failing to build because masix support had been removed in
780the rest of e2fsprogs, so ext2ed no longer has masix support, either.
781
782The configure script now respects the LDFLAGS environment variable if
783it is set when configure is called. (Addresses Sourceforge Feature
784Request: #1937287)
785
786Libuuid is now more portable to the Windows platform. (Addresses
787Sourceforge Feature Request: #1937287)
788
789The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
790bare echo commands so that configure flags such as --quiet work
791correctly. (Addresses Sourceforge Patches: #2058794)
792
793A few uses of sprintf have been removed from the ext2fs library to
794make life easier for bootloaders with a limited libc environment.
795(Addresses Sourceforge Bug: #2049120)
796
797The ext2fs_read_inode() checks the validity of the inode number passed
798to it earlier, to avoid doing some needless work when it would fail
799anyway.
800
801The ext2fs_open() checks the validity of the blocksize parameter
802passed to it earlier, to avoid doing some needless work when it would
803fail anyway.
804
805Disable a very annoying automatic "%.sh -> %" GNU make rule in the
806top-level Makefile. That automatic rule is used to better support
807SCCS, but it caused problems for a particular niche distribution which
808likes to use configure.sh files to store the configure options used to
809build a package. Unfortuntaely GNU make will use the configure.sh to
810replace the configure script, resulting in a self-inflicted fork bomb
811leading to an out-of-memory crash.
812
Theodore Ts'o31d64872008-09-01 10:39:35 -0400813To support old GNU C compilers don't use C99/C++ comments, but only
814K&R style comments, and don't try to use __builtin_expect if __GNUC__
815is less than 3. (__builtin_expect is only supported for gcc versions
8162.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
817this is an optimization, we only try to use __builtin_expect for gcc 3
818and up.)
819
820In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
821__LITTLE_ENDIAN, which are only defined by glibc's header files and
822hence isn't portable.
823
824For the convenience for some distributions that need a static tune2fs,
825the Makefile for misc/ now has a tune2fs.static target.
826
827The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
828for extent-based files
829
830The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
831files.
832
833All source files no longer have any trailing white space.
834
835The io_channel_read_blk64() and io_channel_write_blk64() functions are
836now functions instead of C preprocessor macros to provide better
837forward compatibility.
838
839The e2fpsrogs translation template now expands the @x abbrevation.
840
841Various namespace leackages in libblkid, libe2p, and libext2fs have
842been fixed.
843
844Fix a parallel build problem in e2fsprogs.
845
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400846E2fsprogs is now more portable to Solaris.
847 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
848 are always present.
849 * Scripts do not assume that /bin/true is always in /bin
850 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
851 * Flush stdio handles before calling setbuf(), since Solaris will
852 discard any pending output to the stream.
853 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
854 picky about which C compiler can beused for SUSv3 conformance.
855 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
856 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
857 Since we need some SUSv3 functions, consistently use SUSv3 so
858 that e2fsprogs will build on Solaris using c99.
859 * Solaris C99 does not support varargs C preprocessor macros
860 * Solaris header files pollute the C namespace if in/netinet.h
861 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
862 typedef.
863 * Solaris ships with a pathetically ancient shell in /bin/sh so we
864 avoid the use of various more avanced shell constructs such as $().
865
Theodore Ts'o31d64872008-09-01 10:39:35 -0400866The "make rpm" command will now take some extra configure optiosn from
867the build environment without needing to patch the source tree.
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400868
Theodore Ts'o31d64872008-09-01 10:39:35 -0400869The ext2fs_add_dir_block() function will now grow the dblist more
870aggressively as an optimization to avoid copying the array too often.
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400871
Theodore Ts'o31d64872008-09-01 10:39:35 -0400872The e2fsck_write_bitmaps() will write the block and inode bitmaps
873together instead of in two passes.

875
Theodore Ts'o92e49d82008-07-10 17:24:22 -0400876E2fsprogs 1.41 (July 10, 2008)
877==============================
Theodore Ts'o795de672008-06-18 00:50:05 -0400878
879Add support for ext4 filesystem features, in particular extents,
880uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
881support for checking journal checksums. Debugfs will print new
882superblock and inode fields that were defined for ext4. For example,
883the nanosecond and i_version fields of an inode, and the
884s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
885Note: Resize2fs doesn't currently support the combination of flex_bg
886and !resize_inode. (Addresses Debian Bug: #388452, #425477)
887
888Tune2fs can support migrating a filesystem from using 128 byte inodes
889to 256 byte inodes, so it can take advantage of the full features of
890ext4.
891
892Add support for "undo" support. E2fsck and mke2fs can optionally

Theodore Ts'o92e49d82008-07-10 17:24:22 -0400895E2fsck could damage a filesystem by trying to relocate inode tables
896due to corrupted block group descriptors, where the attempted inode
897table relocation would do far more harm than good. E2fsck has been
898fixed to detect this these sorts of corrupted block group descriptors
899much earlier in e2fsck processing, so it can try to use the backup
900superblock and block group descriptors first. This should be a much
901better strategy for recovering these types of corrupted filesystems.

Theodore Ts'o795de672008-06-18 00:50:05 -0400904E2fsck will display a more understandable message when the last check

913#488663)
914
915Fix mke2fs to use a default block size of 4k when formatting an
916external journal device. This is done by using a fixed filesystem
917type list that consists only of the single filesystem type "journal"
918when looking up configuration keys in /etc/mke2fs.conf. (Addresses
919Debian Bug: #488663)

Theodore Ts'oa41d5ac2008-07-07 15:10:16 -0400924Fix blkid handling of stale devices. Fix a bug which could cause a
925core dump while garbage collecting the blkid cache, and assure that
926blkid_find_dev_with_tag() never returns a non-existent device. Also,
927if a filesystem is found at a new /dev location, eliminate any
928duplicate stale entries which can not be verified.

932blkid's probe function, to reduce the chances of false positives.
933
934The mke2fs program now has a much more sophisticated system for
935controlling configuration parameters of a newly created filesystem
936based on a split filesystem and usage type system. The -t option to
937mke2fs was a deprecated alias to -c; it now specifies a filesystem
938type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
939separated usage list. The filesystem type information and type
940information is used to extract configuration parameters from the
941/etc/mke2fs.conf file.
942
Theodore Ts'o795de672008-06-18 00:50:05 -0400943The mke2fs program will no longer complain and request the -f option

1076Fix a potential data corruption bug in e2fsck in the journal replay.
1077The chances of this is happening is extremely remote, especially the
1078default data=ordered or data=writeback modes. However, if a block
1079which has been journalled starts with the first four bytes 0xc03b3998,
1080when e2fsck replays the journal, those four bytes will be replaced
1081with zero's. Fortunately, it is highly, highly unlikely for e2fsck
1082metadata to begin with those fatal 4 byte sequence, and unless
1083data=ordered mode is in use, data blocks are never journaled.

1169
1170Fixed e2image -I so it works on image files which are larger than 2GB.
1171
1172Fixed e2fsck's handling of directory inodes with a corrupt size field. If
1173the size is larger than the number of blocks found in the inode, don't
1174try to allocate extra empty blocks at the end of the directory to make
1175up the difference; there's no point to doing that. In addition, if
1176the size is not a multiple of a blocksize, always fix it.
1177
1178E2fsck handled a pass 2 "should never happen error" by not giving
1179enough information and then core dumping. Unfortunately, it was all
1180too easy to trigger the "should never happen" situation if a
1181directory's inode size was not correct. This has been fixed, but
1182e2fsck has also been taught how to handle this situation more
1183gracefully, by simply removing the inode hash tree information, so
1184that it can be rebuilt again after e2fsck's pass 3. (Addresses
1185Launchpad Bug: #129395)
1186
1187Resize2fs had a bug resizing large inodes with extended attributes
1188that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
1189completely on big-endian systems such as PowerPC. The bug should be
1190completely fixed now. Yay for regression test suites. (Addresses Red

1222
1223Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
1224depreciate the -s option, since it can result in filesystems which
1225e2fsck can't fix easily. There are very good reasons for wanting to
1226disable sparse_super; users who wants to turn off sparse_super can use
1227debugfs. (Addresses Sourceforge Bug: #1840286)
1228
1229Add missing options to mke2fs's usage message. (Addresses Sourceforge
1230Bug: #1751393)
1231
1232Fix bug in resize2fs when large (greater than 128 byte) inodes are
1233moved when a filesystem is shrunk; it was only moving the first 128
1234bytes, so extended attributes were not getting moved. (Addresses Red
1235Hat Bugzilla: #434893)

1240
1241Allow mke2fs and tune2fs manipulate the large_file feature.
1242Previously we just let the kernel and e2fsck do this automatically,
1243but e2fsck will no longer automatically clear the large_file feature.
1244It still isn't really necessary to worry about this feature flag
1245explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:

1252reporting a free block more than once if there are too few free blocks
1253in the filesystem. (Addresses Sourceforge Bug: #1096315)
1254
1255Change e2fsck to no longer clear the LARGE_FILES feature flag
1256automatically, when there are no more > 2GB files in the filesystem.
1257It's been almost a decade since there have been kernels that don't
1258support this flag, and e2fsck clears it quietly without telling the
1259user why the filesystem has been changed.
1260

1262volume disappears while it is being probed. (Addresses RedHat

1267
1268Fix option syntax in dumpe2fs for explicit superblock and blocksize
1269parameters. What was currently documented in the man page has been
1270broken for some time, due to getopt() implementation changes. The
1271option sytax has been changed to one which is can be more portable
1272supported and which is consistent with the format for extended options
1273in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
1274
1275Add support to tune2fs to clear the resize_inode feature. This

1380===================================
1381
1382Fix a potential overflow big in e2image if the device name is too
1383long.
1384
1385Mke2fs will now create new filesystems with 256 byte inodes and the
1386ext_attr feature flag by default. This allows for much better future
1387compatibity with ext4 and speeds up extended attributes even on ext3
1388filesystems.
1389
1390Teach e2fsck to ignore certain "safe" filesystem features which are
1391set automatically by the kernel. Having the kernel set features
1392automagically behind the user's back is a bad idea, and we should try
1393to break the kernel of this habit, especially for the newer ext4
1394feature flags. But for now, we will try to avoid needless full checks
1395which can annoy users who are doing fresh installs.
1396
1397Add support in tune2fs and mke2fs for making a filesystem as being "ok
1398to be used with test kernel code". This will be needed for using test
1399filesystems with the latest ext4 kernel code.
1400
1401Change e2fsck -fD so that it sorts non-htree directories by inode
1402numbers instead of by name, since that optimizes performances much
1403more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
1404
1405If e2image fills the disk, fix it so it exits right away instead of
1406spewing large numbers of error messages.
1407(Addresses-Sourceforge-Feature-Request: #606508)
1408
1409If ftruncate64() is not available for resize2fs, let it use ftrucate()
1410instead, but have it check to see if the size would get truncated, and
1411skip calling ftruncate in that case.
1412
1413Add support for detecting HFS+ filesystems in the blkid library.
1414
1415Add supprt in the blkid library for ext4/ext4dev filesystems.
1416
1417Fix a bug in blkid where it could die on a floating point exception
1418when presented with a corrupt reiserfs image.
1419
1420Fix blkid's handling of ntfs UUID's so that leading zeros are printed
1421such that UUID string is a fixed length.
1422
1423Add sample python bindings for the uuid library to the contrib
1424directory. (Addresses-Sourceforge-Patches: #778817)
1425
1426Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
1427will work with large files. (Addresses Sourceforge Feature Request:
1428#1257500 and Sourceforge Support Request: #1253511)
1429
1430Allow the debugfs 'undel' command to undelete an inode without linking
1431it to a specific destination directory, since this might require
1432allocating blocks that could overwrite some yet-to-be-recovered
1433deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
1434

1452especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,

1459
1460Remove the --enable-dynamic-static configure option, and build e2fsck
1461dynamically by default. If the user wants e2fsck.static, he/she will
1462need to build it via "make -C e2fsck e2fsck.static"

1469====================================
1470
1471Improve time-based UUID generation. A new daemon uuidd, is started
1472automatically by libuuid if necessary. This daemon is setuid to allow
1473updates to /var/lib/libuuid, so the clock sequence number can be
1474stored and so if the clock is set backwards, it can be detected.

1478Filter out the NEEDS_RECOVERY feature flag when writing out the backup
1479superblocks. This avoids e2fsck from concluding that a full
1480filesystem check is required before backing up the superblock due to
1481changes in the feature flags. (Addresses Debian Bug: #454926)
1482
1483Fix fsck to only treat the '#' character as a comment at the beginning
1484of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
1485will cause fsck to issue an bogus warning message.

1524===================================
1525
1526Fix a potential security vulnerability where an untrusted filesystem
1527can be corrupted in such a way that a program using libext2fs will
1528allocate a buffer which is far too small. This can lead to either a
1529crash or potentially a heap-based buffer overflow crash. No known
1530exploits exist, but main concern is where an untrusted user who
1531possesses privileged access in a guest Xen environment could corrupt a
1532filesystem which is then accessed by the pygrub program, running as
1533root in the dom0 host environment, thus allowing the untrusted user to
1534gain privileged access in the host OS. Thanks to the McAfee AVERT
1535Research group for reporting this issue. (Addresses CVE-2007-5497.)
1536
1537Fix hueristics in blkid which could cause a disk without partitions to
1538be incorrectly skipped when a loopback device is present. (Addresses
1539Red Hat Bugzilla #400321.)
1540
1541Fix e2image so that in raw mode it does not create an image file which
1542is one byte too large.
1543
1544Change mke2fs's usage message so it recommends the preferred -E option
1545instead of the deprecated -R option.
1546
1547Enhance the blkid library so it will recognize squashfs filesystems.
1548(Addresses Red Hat Bugzilla #305151.)
1549
1550Enhance e2fsck so it will force the backup superblocks to be backed up
1551if the filesystem is consistent and key constants have been changed
1552(i.e., by an on-line resize) or by e2fsck in the course of its
1553operations.
1554
1555Enhance blkid's detection of FAT filesystems; so that USB disks with
1556only a single bootable partition will not get missed.
1557
1558E2fsck will no longer mark a filesystem as invalid if it has time
1559errors (i.e., if superblock mount time or last write time is in the
1560future) and the user refuses to fix the problem.
1561
1562The Ubuntu init scripts don't properly set the system time correctly
1563from hardware clock if the hardware clock is configured to tick local
1564time instead of GMT time. Work around this as best as we can by
1565providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
1566be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
1567Bug #131201.)
1568
1569Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
1570Hat Bugzilla #151533.)
1571
1572Fix e2fsck so that if the superblock is corrupt, but still looks
1573vaguely like an ext2/3/4 superblock, that it automatically tries to
1574fall back to the backup superblock, instead of failing with a hard
1575error.
1576
1577Make the e2fsprogs program more robust so that they will not crash
1578when opening a corrupt filesystem where s_inode_size is zero.
1579
1580Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
1581arguments are detected as such and the parse error is reported to the
1582user. (Addresses Debian Bug #435381.)
1583
1584Change e2fsck so it will not complain if a file has blocks reallocated
1585up to the next multiple of a system's page size.
1586
1587Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
1588about (valid) filesystems where the inode table extends to the last
1589block of the block group. (Addresses Red Hat Bugzilla #214765.)
1590
1591Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
1592allocating inode tables for some relatively rare odd disk sizes.
1593(Addresses Red Hat Bugzilla #241767.)
1594
1595Add Catalan translation and update Dutch and Swedish translations
1596from the Translation Project.
1597
1598Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
1599still had an issue when trying to figure out whether we need to
1600byte-swap fast symlinks that contained extended attributes.

1611Add "make check" to the RPM spec file
1612
1613Fix "make install" and 'make unstall" in misc/Makefile.in so that it
1614works correctly when the prefix is not the root directory.
1615
1616Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
1617clena up after themselves by deleting the test.img temporary file
1618after completing the test.
1619
1620Fixed a corner case bug ext2fs_unlink() when trying to delete the
1621first directory entry in a directory block and the last directory
1622entry in the previous directory block is not in use. Fortunately
1623ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
1624places where it is extremely unlikely to run into this corner case.
1625
1626Fix missing dependency which would cuase parallel builds to fail.
1627(Addresses Sourceforge Bug #1842331.)
1628

1630calling open(O_CREATE) with a missing mode parameter.
1631
1632Fix the test_ss.c in lib/ss so it can be used as an example
1633application program for the library as well as a regression test
1634suite.

1640================================
1641
1642A recent change to e2fsck_add_dir_info() to use tdb files to check
1643filesystems with a very large number of filesystems had a typo which
1644caused us to resize the wrong data structure. This would cause a
1645array overrun leading to malloc pointer corruptions and segfaults.
1646Since we normally can very accurately predict how big the the dirinfo
1647array needs to be, this bug only got triggered on very badly corrupted
1648filesystems.
1649
1650Fix a bug in e2fsck which caused it to incorrectly salvange
1651directories when the last entry's rec_len is bogusly too big. This
1652resulted in a nonsense filesystem corruption to be reported, and
1653required a second run of e2fsck to fully fix up the directory.

1665Fix bug which could cause libblkid to loop forever. When revalidating
1666a partition where there is obsolete information in /etc/blkid.tab, we
1667end up freeing a the type tag without clearing dev->bid_type, causing
1668blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
1669
1670The Turkish translation has a bug in it where it has the translation
1671of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
1672@E, recursively, forever, until the stack fills up and e2fsck core
1673dumps. We fix this by making e2fsck stop @-expansions after a
1674recursive depth of 10, which is far more than we need.

1678getting surprised by mke2fs creating filesystems with different

1693Fix bogus strip permission errors when building under Debian. When

1701Add new function: profile_set_default(). This function sets the value
1702of the pseudo file "<default>". If the file "<default>" had
1703previously been passed to profile_init(), then def_string parameter
1704will be parsed and used as the profile information for the "<default>"

1711Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
1712priority" environment variable that overrides all others, where as
1713LANG is the lowest priorty environment variable. If LC_ALL is set, it
1714doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and

1727
1728Fix a bug in libblkid which could cause the internal field bid_type to
1729become corrupted. Fortunately bid_type isn't used much, and bid_label
1730and bid_uuid is only used by debugging code, so the impact of this bug
1731was very minor.
1732
1733Mke2fs will now store the RAID stride value when a filesystem is
1734created with a requested RAID stride, and then use it automatically in
1735resize2fs.
1736
1737Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
1738isn't too big. In some cases Lustre users have tried specifying an
1739inode size of 4096 bytes, while keeping an inode ratio of one inode
1740per 4096 bytes.
1741
1742Improve sanity check in e2fsck's algorithm for finding a backup
1743superblock, so that it won't accidentally find a superblock that was
1744located in the journal, and then later reject it as being not a valid
1745backup superblock.
1746
1747Fix e2fsck get_size logic so that it will work with the Linux floppy
1748driver. The Linux floppy driver is a bit different from the other
1749block device drivers, in that if the device has been opened with
1750O_EXCL, it disallows another open(), even if the second open() does
1751not have the O_EXCL flag. (Addresses Debian Bug: #410569)

1760Change the blkid library to be much more paranoid about concluding
1761that a partition contains an NTFS filesystem, and fetch the UUID and
1762LABEL information from NTFS filesystems. (Addresses Launchpad Bug:

1769journal inode was cleared to due it being corrupt after finishing the
1770filesystem check.
1771
1772Fix e2fsck so that it updates the journal inode if it is corrupted and
1773the backup journal information from the superblock was successfully
1774used to recover the filesystem.
1775
1776Fix e2fsck so that it checks all of the blocks in the journal inode
1777for validity. The original code only checked the direct blocks to
1778make sure the journal inode was sane. Unfortunately, if some or all
1779of the indirect or doubly indirect blocks were corrupted, this would
1780not be caught.
1781
1782Add support in blkid to detect LUKS encrypted partitions.
1783
1784Add extra sanity checks for extended attributes in the case where the
1785size is zero but the offset is very large.
1786
1787Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
1788and ext2fs_get_next_inode_full().
1789
1790Clarify the copyright licenses used by the various libraries in
1791the top-level COPYING file (Red Hat Bugzilla: 166058)
1792
1793Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
1794
1795Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
1796
1797Remove check in e2fsck which requires EA's in inodes to be sorted;
1798they don't need to be sorted, and e2fsck was previously wrongly
1799clearing unsorted EA's stored in the inode structure.
1800
1801Allow mke2fs or tune2fs to create a substantially larger journal (up
1802to 10,240,000 blocks).
1803
1804Fix MD superblock detection, and make sure the correct UUID is
1805reported from the MD superblock.
1806
1807Fix a signed vs. unsigned bug in debugfs.
1808
1809Enhance debugfs's date parser so that it accepts integer values.
1810
1811Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
1812file with multiply claimed blocks is hard linked. or not at all if the
1813root directory contains shared blocks
1814
1815Enhance debugfs so it can modify the block group descriptors using the
1816command set_block_group_descriptor.
1817
1818Improve e2fsck's reporting of I/O errors so it's clearer what it was
1819trying to do when an error happens
1820
1821Fix a bug in in how e2fsprogs byte swaps inodes containing fast
1822symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
1823#232663 and LTC Bugzilla: #27634)
1824
1825Fix potential file descriptor leak in ext2fs_get_device_size() in an
1826error case.
Theodore Ts'oa0d42542007-04-07 11:05:10 -04001827
1828Add libreadline.so.5 support to libss.
1829
1830Impove badblocks -n/-w exclusive usage message.
1831
1832Fix dump_unused segfault in debugfs when a filesystem is not open
1833
1834Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
1835
1836Allow the debugfs lcd command to work w/o a filesystem being open.
1837(Addresses LTC Bugzilla #27513)
1838
1839Fix e2fsck to clear i_size for special devices with a bogus i_blocks
1840field on the first pass.
1841
1842Fix e2fsck to set the file type of the '..' entry when connecting
1843a directory to lost+found. (Addresses Lustre Bug: #11645)
1844
1845Enhance e2fsck to recover directories whose modes field were corrupted
1846to look like special files. This is probably only useful in
1847artificial test cases, but it will be useful if we ever do the "inodes
1848in directory" idea for ext4.
1849
1850Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
1851#412614)
1852
1853Fix resize2fs parsing of size parameter (in sector units). This was
1854actually a bug in libe2p's parse_num_blocks() function. When handling
1855the 's' suffix, it was ignoring the blocksize information passed in
1856from the caller and always interpreting the number in terms of a 1k
1857blocksize. (Addresses Debian Bug: #408298)
1858
1859There was a floating point precision error which could cause e2fsck to
1860loop forever on really big filesystems with a large inode count.
1861(Addresses Debian Bug: #411838)
1862
1863Fix memory leak in ext2fs_write_new_inode()
1864
1865Add support for using a scratch files directory to reduce e2fsck's
1866emory utilization on really big filesystems. This uses the TDB
1867library. See the [scratch_files] section of the e2fsck.conf man page
1868for more details.

1870Fixed type-punning bug which caused dumpe2fs to crash on the Arm
1871platform (Addresses Debian Bug: #397044)
1872
1873Add explanatory message to badblocks that -n and -w are mutually exclusive
1874(Addresses Debian Bug: #371869)
1875
1876Allow debugfs and dumpe2fs to support fs features under development.
1877
1878Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
1879ext2fs_open() , which allows application to open filesystes with features
1880which are currently only partially supported by e2fsprogs.
1881
1882Allow unix_io to support offsets greater than 2G (Addresses
1883SourceForge Bug: #1547922)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001884
1885Fixed overflow and signed/unsigned problems caused by the number of
Theodore Ts'o7809bc52006-11-14 23:49:07 -05001886blocks or inodes exceeding 2**31 or being close to 2**32-1.
1887
1888Add support for unsigned directory hash calculations with hints in the
1889superblock to fix cross-architectural portability for htree
1890directories with filenames where the high 8th bit is set. (Addresses
1891Debian: #389772)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001892
1893Fix resize2fs so that it gives user-intelligible error messages if the
1894filesystem or the kernel does not support on-line resizing.
1895(Addresses Debian Bug: #380548)
1896
1897Require mke2fs -F -F for really dangerous operations, since -F is
1898needed for less dangerous operations such as creating filesystems
1899images in regular files, or creating filesystems on whole block
1900devices. These relatively innocuous usages should NOT be confused
1901with running mke2fs on an apparently-mounted or in-use filesystem.
1902
1903Allow the default inode size to be specified into the mke2fs.conf
1904file.
1905
1906Make the smallest default journal size is big enough so that on-line
1907resizing should always work.
1908
1909Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
1910#1531372)
1911
1912Fix debugfs coredump when lsdel is run without an open filesystem
1913(Addresses Debian Bug: #378335)
1914
1915Fix debugfs display bug us that bytes that have the high bit set are
1916displayed as "ec" instead of "ffffffec".
1917
1918Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
1919
1920Device mapper scanning wasn't working in the blkid library because the
1921pathnames had an extra "/dev" when they were being probed.
1922
1923Add GFS/GFS2 support to the blkid library.
1924
1925Fix blkid support of empty FAT filesystem labels.
1926
1927Avoid recursing forever (or for a long time) when the blkid library
1928searches for a device and there are symlinks to directories in /dev.
1929
1930Avoid unaligned halfword access in blkid when accessing FAT
1931superblocks, as this will cause Sparc/Solaris systems to throw a
1932SIGBUS error.
1933
1934The latest devmapper libraries requires pthreads, add -lpthreads to
1935the static link libraries for e2fsck.static if devmapper is enabled.

1937
1938Improve the (non-installed, for experts only) findsuper program by
1939printing the uuid and label from the superblocks, as well as the
1940starting and ending offsets of the filesystem given the information in
1941the superblock. Omit by default printing superblocks that are likely
1942found in located in an ext3 journal unless an explicit -j option is
1943given.
1944
Theodore Ts'o80dda9b2007-12-03 18:33:39 -05001945Updated Spanish, French and Dutch translations and added Catalan
1946translation. (Addresses Debian bug: #411562)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001947
1948Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
1949determining a partition's size, since binary searching to determine
1950the device doesn't work on FreeBSD.
1951
Theodore Ts'od7b64722007-06-24 17:32:47 -04001952Documentation about UUID's is available in enough places, and it's
1953awkward to deal with debian-legal's insanities. So I'm caving in the
1954"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
1955don't have do the dfsg tarball. Also remove the rule that only tried
1956to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
1957e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
1958
1959Fix the info-dir line so that the menu name does not contain a .info
1960prefix. First of all, it's ugly, secondly, it causes the install-info
1961command to fail to remove the com_err info file from the
1962/usr/share/info/dir file when the comerr-dev package is removed and
1963purged. (Addresses Debian Bug: #401711)

1973Programmer's notes:
1974-------------------
1975
Theodore Ts'oa0d42542007-04-07 11:05:10 -04001976E2fsck now supports the %It expansion when printing a problem report.
1977It will print the type of the inode in the problem context.
1978
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001979Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
1980(Addresses Sourceforge Bug: #1565561)
1981
1982Remove unused variables and other lint/gcc -Wall cleanups
1983
1984Add check to ext2fs_get_device_size() so it will return EFBIG for for
1985filesystems contained in regular files where the filesystem image size
1986is returned by stat64().
1987
Theodore Ts'o7809bc52006-11-14 23:49:07 -05001988Set local environment variables to C so mk_cmds and compile_et always
1989work. (Addresses SourceForge Bug: #1532177)
1990
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001991Added the 64-bit byte swapping function ext2fs_swab64().
1992
1993Added two new helper functions to prevent 2**31/2**32-1 overflow
1994problems: ext2fs_div_ceil() and e2p_percent().
1995
1996Create new ext2fs library inline functions ext2fs_group_first_block()
1997and ext2fs_group_last_block() in order to calculate the starting and
1998ending blocks in a block group.
1999
2000Create the generated files read-only to remind developers not to edit them.
2001
Theodore Ts'o7809bc52006-11-14 23:49:07 -05002002Add support for autoconf 2.60 (with backwards compatibility for older
2003versions of autoconf).
2004
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04002005Added an "make rpm" target to top-level Makefile
2006
2007Added various FreeBSD portability fixes.
2008
2009Exclude mercurial files from the RPM build tree to speed up copy/build.
2010
2011Use root_sysconfdir to define the locations of mke2fs.conf and
2012e2fsck.conf instead of using a hard-coded /etc pathname.
2013
2014Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
2015
2016Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
2017
2018If diff -u is supported, use it to report test failures.
2019
2020Updates/improvements to RPM spec file
2021
Theodore Ts'o7809bc52006-11-14 23:49:07 -05002022Add on-disk format definitions for the following new features:
2023EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
2024EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
2025EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
2026
2027Add a new make target "checked-failed" in the tests directory which
2028reruns any failed tests
2029
2030Update draft-leach-uuids-guids-01.txt with rfc4122.txt
2031
Theodore Ts'oa0d42542007-04-07 11:05:10 -04002032Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
2033pointer dereferences, memory leaks, etc. None were security-criticial
2034problems.
2035
2036Fix up usage and decrement error messages in the test_icount program
2037
2038Add debugging code to the com_err library; if the environment variable
2039COMERR_DEBUG is set to 1, print out debugging messages as error tables
2040are added and removed from the com_err library. If the
2041COMERR_DEBUG_FILE environment variable is set (and the process is not
2042setuid) the debugging messages may be redirected to a file.
2043
2044Change all of the e2fsprogs programs to use the newer add_error_table()
2045and remove_error_table() interfaces instead of the much older
2046initialize_*_error_table() function.
2047
2048Add TDB support into the ext2fs library. This allows us to have a
2049guaranteed library we can count on always being present so we can
2050store data in an on-disk database.
2051
2052Add support for using TDB to store the icount data, so we don't run out
2053of memory when checking really large filesystems.
2054
Theodore Ts'od7b64722007-06-24 17:32:47 -04002055Change the regression test suite so that it skips empty test directories.
2056
2057Define the l_i_iversion field in ext2_inode. The l_i_version field is
2058now defined from the old l_i_reserved1 field in the ext2 inode. This
2059field will be used to store high 32 bits of the 64-bit inode version
2060number.
2061
2062Add Makefile production rule for e2fsprogs.spec in case it gets
2063deleted.
2064
2065Add new function profile_get_uint() to allow for a clean way to fetch
2066unsigned integers from the context.
2067
2068Add test to make sure the ext2 superblock structure is 1024 bytes.
2069
2070Fix typo in name of f_dup4 regression test
2071
2072Add new function blkid_gc_cache() which performs a garbage collection
2073pass on the /etc/blkid.tab file.
2074
2075The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
2076general, only e2fsck (after the filesystem is clean), tune2fs, and
2077resize2fs should change the backup superblocks by default. Most
2078callers of ext2fs_open() should not be touching any superblock fields
2079which require the backups to be touched.
2080
2081Add new function to libext2fs, ext2fs_default_journal_size(), which
2082returns the default journal size.
2083
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04002084
Theodore Ts'o6c094752006-05-29 11:47:25 -04002085E2fsprogs 1.39 (May 29, 2006)
2086=============================
Theodore Ts'o34a26112006-03-29 20:40:23 -05002087
Theodore Ts'o34a26112006-03-29 20:40:23 -05002088Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
2089between 2**31 and 2**32 blocks.
2090
Theodore Ts'o34a26112006-03-29 20:40:23 -05002091Change mke2fs to use /etc/mke2fs.conf as a configuration file to
2092configure the filesystem features, blocksize, and inode_ratio for
2093different filesystem types.
2094
Theodore Ts'o6c094752006-05-29 11:47:25 -04002095Mke2fs will now create filesystems hash trees and on-line resizing
2096enabled by default, based on the new /etc/mke2fs.conf file.
2097
Theodore Ts'o34a26112006-03-29 20:40:23 -05002098The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
2099filesystem device node in exclusive mode to prevent accidents by
2100system administrators. In the case of resize2fs and mke2fs, it will
2101only use exclusive mode if the filesystem is not mounted.
2102
2103Fixed a bug in mke2fs which caused it to to fail when creating the
2104resize inode for large filesystems. (Addresses Debian Bug #346580)
2105
Theodore Ts'obae55642006-05-14 17:31:48 -04002106When allocating space for the RAID filesystems with the stride
2107parameter, mke2fs will now place each portion of the group's inode
2108table right up after the superblock (if present) in order to minimize
2109fragmentation of the freespace.
2110
2111Speed up mke2fs and e2fsck by writing inode and block bitmaps more
2112efficiently by writing the inode and block bitmaps in one pass, thus
2113reducing the number of disk seeks required.
2114
Theodore Ts'o34a26112006-03-29 20:40:23 -05002115Add support for on-line resizing to resize2fs.
2116
2117Fix blkid library so that logic to determine whether or not a device's
2118cached information in /etc/blkid.tab needs to be verified or not
2119doesn't get confused by a system clock which is insane (for example,
2120if the battery is dead on a Macintosh running PPC Linux. (Addresses
2121Red Hat Bug: #182188)
2122
2123The blkid library will now store the UUID of the external journal used
2124by ext3 filesystems, so that in the future, the userspace mount binary
2125can use this to find the location of the external journal and pass
2126this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -05002127
2128E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -05002129control how various options should be handled. See the e2fsck.conf
2130man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -05002131
Theodore Ts'o34a26112006-03-29 20:40:23 -05002132E2fsck now prints an explanatory message when delaying a filesystem
2133check when the system is running on battery. (Addresses Debian Bug:
2134#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002135
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002136E2fsck will detect if the superblock's last mount field or last write
2137field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -05002138#327580) These problems will be fixed automatically in preen mode
2139since Debian's boot sequence bogusly doesn't set the time correctly
2140until potentially very late in the bootup process, and this can cause
2141false positives which will cause users' systems to fail to boot.

2145the external journal is incorrect, and if so, offer to update it.
2146(Addresses Debian Bug: #355644)
2147
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002148Fix e2fsck from segfaulting on disconnected inodes that contain one or
2149more extended attributes. (Addresses Debian Bug: #316736, #318463)
2150
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002151E2fsck will stop and print a warning if the user tries running a
2152read/write badblocks test on a read-only mounted root filesystem.
2153
Theodore Ts'obae55642006-05-14 17:31:48 -04002154Fix a memory leak in e2fsck's error paths. (Thanks to Michael
2155C. Thompson for pointing these out; they were originally found using
2156Coverity.)
2157
Theodore Ts'of3227852005-12-31 16:45:29 -05002158When resizing a file containing a filesystem, resize2fs will expand or
2159truncate a file as necessary. (Addresses Debian Bug: #271607)

Theodore Ts'obae55642006-05-14 17:31:48 -04002161Resize2fs will now automatically determine the RAID stride parameter that
2162had been used to create the filesystem, and use that for newly created
2163block groups. The RAID stride parameter may also be manually specified
2164on the command line using the new -S option to resize2fs.
2165
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002166Fix mke2fs so that it correctly creates external journals on
2167big-endian machines (such as a S/390).
2168
Theodore Ts'obae55642006-05-14 17:31:48 -04002169Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
2170fail to print out the journal or hash seed UUID. (Thanks to Guillaume
2171Chambraud for pointing this out.)
2172
2173Dumpe2fs will now print the size of the journal (if present).
2174
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002175Fix debugfs's set_inode_field command so it can properly set the frag,
2176fsize, uid_high, gid_high, and author fields in the inode instead of
2177silently failing, and so that setting the i_size actually sets i_size
2178correctly.
2179
2180Add a new debugfs command, set_current_time, which sets fs->now so
2181that regression test suites can repeatedly modify the filesystem's
2182last_write fields.
2183
Theodore Ts'o34a26112006-03-29 20:40:23 -05002184Fix a bug in debugfs's icheck which would incorrectly report the owner
2185of an extended attribute block.
2186
Theodore Ts'obae55642006-05-14 17:31:48 -04002187Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
2188print a usage message when an illegal option character is given.
2189
Theodore Ts'o6c094752006-05-29 11:47:25 -04002190Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
2191so it won't core dump. (Addresses SourceForge bug #1424311)
2192
Theodore Ts'obae55642006-05-14 17:31:48 -04002193Fix mklost+found so that it creates a full-sized directory on
2194filesystems with larger block sizes.
2195
2196Fix a file descriptor leak in blkid library.
2197
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002198Fix a display bug in "badblocks -sv" so that the done message properly
2199clears the block number at the end of the test. (Addresses Debian Bug
2200#322231)
2201
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002202Allow fractional percentages to the -m option in mke2fs and tune2fs
2203(Addresses Debian Bug: #80205)
2204
2205Use fstat/fstat64 in getsize.c if the the target is a regular file,
2206instead of attempting to do a binary search. Fix some fd leaks in
2207error cases.
2208
Theodore Ts'o34a26112006-03-29 20:40:23 -05002209Add support for device mapper library to the blkid library to ensure
2210that the "best" (i.e., leaf) device is probed by the blkid library.
2211
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002212Fix the blkid library so that it notices when an ext2 filesystem is
2213upgraded to ext3.
2214
2215Improve the blkid's library VFAT/FAT detection; it now understands
2216labels stored in the root directory, and is more paranoid about
2217checking the FAT superblock values.
2218
Theodore Ts'o34a26112006-03-29 20:40:23 -05002219Fixed a fd leak in the uuid library which was causing problems for the
2220LVM tools. (Addresses Debian Bug: #345832)
2221
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002222Add support for the reiser4 and software suspend partitions to the
2223blkid library. Also add support for extract the label from iso9660
2224filesystems.
2225
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002226Fix a compile_et bug which miscount the number of error messages if
2227continuations are used in the .et file.
2228
2229Add extra sanity checks to protect users from unusual cirucmstances
2230where /etc/mtab may not be sane, by checking to see if the device is
2231reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
2232#319002)
2233
Theodore Ts'o34a26112006-03-29 20:40:23 -05002234Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian

Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002237Fix use-after-free bug in e2fsck when finishing up the use of the
2238e2fsck context structure.
2239
Theodore Ts'o34a26112006-03-29 20:40:23 -05002240Fixed spelling mistakes, typos, and otherwise clarified man pages and
2241documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

2251Programmer's notes:
2252-------------------
2253
Theodore Ts'o7e2ec012006-04-22 04:29:16 -04002254Update config.guess and config.sub to latest version (2006-02-23) from
2255FSF.
2256
2257Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
2258Bugs: #360661, #360317)
2259
Theodore Ts'o34a26112006-03-29 20:40:23 -05002260Fixed the Makefile so that they work correctly on newer versions of
2261GNU make (i.e., 3.81).
2262
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002263Add valgrind support to the regression test suites, and eliminate
2264false positives from valgrind.
2265
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002266Add a regression test suite for the blkid library.
2267
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002268Fix a fencepost error in resize2fs caught by valgrind.
2269
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002270Fix compiler warnings about missing memcpy prototypes.
2271
2272We no longer have the sparc assembly code in the header file any more,
2273so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
2274break compiles on the sparc architectures when using gcc.
2275
2276In the libext2fs library, add the new field fs->now which if non-zero
2277is used instead of the system time when setting various filesystem
2278fields (last modified time, last write time, etc.)
2279
2280Fix gcc 4.01 complaints by adding a missing #include <string.h> to
2281ext2fs.h which is needed since the inline functions use memcpy().
2282(Addresses Sourceforge Bug #1251062)
2283
2284Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
2285the build system when building files in the util directory which are
2286needed during the build process. This avoids potential problems when
2287cross-compiling and some of the options specified in CFLAGS or LDFLAGS
2288are not recognized as valid by the host compiler. (Addresses
2289Sourceforge Bug #1261547)
2290
2291Clean up the blkid library by making the superblock and generic i/o
2292functions to be more generic. Clean up interface to the probe
2293function, and fix memory leak. Finallly, remove an unneeded reference
2294to probe.h in the lib/blkid/resolve.c
2295
Theodore Ts'o3285a9c2005-12-10 23:05:30 -05002296Add an ext2fs_read_bb_FILE regression test to confirm proper detection
2297of invalid block #'s.
2298
Theodore Ts'o34a26112006-03-29 20:40:23 -05002299The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
2300indicate that the the function read/writes the memory location.
2301
Theodore Ts'o3285a9c2005-12-10 23:05:30 -05002302Fix various gcc -Wall complaints.
2303
2304Add a dependency to make sure that the subdirectories are created
2305before creating all of the object files, in order to address parallel
2306build problem in the library Makefiles. (Addresses Sourceforge Bug:
2307#1261553)
2308
2309Add $(LDFLAGS) to the command line argument when generating an ELF or
2310Solaris shared library, to allow cross-compile and other builds that
2311might need to specify -L paths to needed libraries. (Addresses
2312Sourceforge Bug #1261549)
2313
Theodore Ts'obae55642006-05-14 17:31:48 -04002314Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
2315intended for testing purposes. It allows an ext2/ext3 developer to
2316create very large filesystems using sparse files where most of the
2317block groups are not initialized and so do not require much disk
2318space. Eventually it could be used as a way of speeding up mke2fs and
2319e2fsck for large filesystem, but that would be best done by adding an
2320RO_COMPAT extension to the filesystem to allow the inode table to be
2321lazily initialized on a per-block basis, instead of being entirely
2322initialized or entirely unused on a per-blockgroup basis.
2323
Theodore Ts'o6c094752006-05-29 11:47:25 -04002324Fix backwards compatibility so e2fsprogs will better compile on Linux
23252.0.35 systems.
2326
2327Make test scripts more robust against locale-related environment variables
2328
2329Fix type warning problem with sizeof() in ext2fs_open2().
2330
2331Fix type warning problem with time_t in debugfs.

Theodore Ts'ofea95ff2005-07-01 17:31:55 -05002334E2fsprogs 1.38 (June 30, 2005)
Theodore Ts'o1f965c82005-06-30 20:06:45 -04002335==============================
2336
2337Fix blkid's test programs (built with "make check") compile correctly
2338even without "configure --enable-blkid-debug".
2339
2340Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
2341type aliasing rules on newer gcc compilers. (Addresses Red Hat
2342Bugzilla ##161183.)
2343
2344Fix com_err library to make it more compatible with recent changes
2345made to the com_err library in MIT Kerberos V5 version 1.4.
2346(Addresses Sourcefroge Bug #1150146)
2347
2348General cleanup of messages printed by e2fsprogs programs for grammar,
2349consistency, and to make life easier for translators. Fixed a few
2350strings containing English that had not been marked as needing
2351translations. Removed strings that do not need to be translated, to
2352make life easier for translators.
2353
2354Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
2355test to see if a device appears to be in use instead of just relying
2356on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
2357
2358Fix portability problem in the filefrag program affecting platforms
2359where the size of an integer is smaller than the size of a long.
2360(Addresses Debian Bug #309655)
2361
2362Mke2fs will now use a larger journal by default for filesystems
2363greater than 4GB. (128 MB instead of 32MB).
2364
2365Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
2366unless forced. This is to avoid signed vs. unsigned kernel bugs in
2367block numbers that still need to be fixed.
2368
2369The blkid program has a new option which will more efficiently search
2370for device when it is known (or expected) that only one matching
2371device will be found in the system, such as when doing a lookup by
2372UUID.
2373
2374Debian's e2fsprogs-specific initrd fragment will avoid including
2375unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
2376and LD_LIBRARY_PATH, and filtering out libraries found in
2377/etc/ld.so.preload. (Addresses Debian Bug: #304003)
2378
2379Fixed a potential portability issue in the blkid programs for
2380architectures where the char type is unsigned. (Addresses Sourceforge
2381Bug: #1180585)
2382
2383Fix a bug in filefrag so that it doesn't falsely count an extra
2384discontinuity when the first block found is an indirect block.
2385(Addresses Debian Bug #307607).
2386
2387Fix blkid's recognition of cramfs filesystems, and enhance it to be
2388able to handle cramfs labels.
2389
2390Fix debugfs's stat command to not core dump when a filesystem is not
2391open.
2392
2393Fix e2fsck's handling of error conditions caused by the resize inode
2394claiming blocks that are also used by other inodes, a filesystem
2395corruption which was commonly caused by a bug in Fedora Core 3's
2396resize2fs program.
2397
2398Fixed bug in filefrag which caused it to fail on non-ext2/3
2399filesystems. (Addresses Debian Bug: #303509)
2400
2401If the superblock last mount time indicates that the system clock may
2402not be accurate, then e2fsck will omit checking inodes' deletion time
2403field for indications of a potential corrupted orphaned inode list.
2404(Previously e2fsck only ommited these LOW_DTIME checks when the
2405superblock's last write time looked insane.)
2406
2407Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
2408(Addresses Debian bug #302200)
2409
2410Make the blkid library more paranoid about being run from setgid
2411programs, and to use __secure_getenv() from libc if it is available.
2412
2413Fixed spelling mistakes, typos, and otherwise clarified man pages.
2414(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
2415and Sourceforge Bug: #1189803)
2416
2417Updated and fixed translations.
2418
2419Fixed various Debian packaging issues --- see debian/changelog for
2420details.
2421
2422Programmer's notes:
2423-------------------
2424
2425Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
2426changed to take an unsigned int for the bit number. Negative bit
2427numbers were never allowed (and didn't make any sense), so this should
2428be a safe change. This is needed to allow safe use of block numbers
2429greater than or equal to 2**31.
2430
2431The compile_et program will avoid recreating generated foo_err.c and
2432foo_err.h files if no changes are necessary. The compile_et program
2433will also atomically replace these files to avoid a potential parallel
2434build race problem on SMP systems. (Addresses Sourceforge Bug:
2435#1157933)
2436
2437Added a new function to the blkid library, blkid_probe_all_new(),
2438which only probes newly added disk devices, and change
2439blkid_find_dev_with_tag() to use this function so that when a
2440requested tag is not found, devices that were previously not checked
2441are searched before searching all devices in the system.
2442
2443Added new functions to the blkid library, blkid_dev_set_search() and
2444blkid_dev_has_tag().
2445
2446E2fsck's problem strings can now use @m and @n as abbrevations for
2447"multiply-claimed" and "invalid", respectively.
2448
2449The e2fsprog.pot file now has an explanation of how the @-expansion
2450and %-expansion works, and strings in e2fsck/problem.c which contain @
2451characters now have comments in e2fsprogs.pot with the @-expansion to
2452make life easier for translators.
2453
2454Fixed missing return values in the ext2fs library which could cause it
2455to return random garbage in certain error conditions.
2456
2457Allow the current time to be overriden via the E2FSCK_TIME environment
2458variable for use in regression tests.
2459
2460The test scrpit driver program now exits with a non-zero status if
2461there any of its test that it ran failed.
2462
2463Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
2464Bug: #1157933)
2465
2466Fixed "make check" so that it compiles correctly even when e2fsprogs'
2467header files have not be installed in the system include directories.
2468(Addresses Sourceforge Bug: #1180572)
2469

Theodore Ts'ofd4b28e2005-03-21 22:37:03 -05002473E2fsprogs 1.37 (March 21, 2005)
2474===============================
2475
2476Add support for checking the validity of Extended Attributes stored in
2477inodes to e2fsck.
2478
2479Add support for dumping the contents of large inodes to debugfs,
2480including the extended attributes stored in inodes.
2481
2482Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
2483when we create a new inode we make sure that the extra information in
2484the inode (any extra fields in a large inode and any ea-in-inode
2485information) is initialized correctly. This can take place when
2486mke2fs creates the root and lost+found directory, when e2fsck creates
2487a new root inode or a new lost+found directory, and when the user uses
2488the debugfs write, mknod, or mkdir commands. Otherwise, the newly
2489create inode could inherit garbage (or old EA information) from a
2490previously deleted inode.
2491
2492Fixed a bug in e2fsck so it would notice if a file with an extended
2493attribute block was exactly 2**32 blocks, such that i_blocks wrapped
2494to zero.
2495
2496Added support to filefrag to detect files which are using the new
2497experimental file extents format, and use the non-ext2 algorithm in
2498that case. Fixed a bug to avoid reporting a false discontinuity if
2499there is one or more unallocated blocks at the beginning of a file.
2500
2501Duplicated a check for noticing whether or not the number of blocks
2502(given a certain blocksize) is greater than 2**32 when the
2503BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
2504allows mke2fs to automatically use a larger blocksize when creating a
2505filesystem on a very large device when run on systems that do not
2506support BLKGETSIZE64.
2507
2508Fix the I18N build which was broken in e2fsprogs 1.36 because the
2509build system had been switched to treat the .gmo files as shipped
2510files (for backwards compatibility with systems that have older GNU
2511I18N tools installed), but the gen_tarball.in script was still
2512removing the .gmo files from the official source distribution.
2513
2514Fixed various Debian packaging issues --- see debian/changelog for
2515details. (Addresses Debian Bugs ##296769, #299341)
2516
2517Programmer's notes:
2518-------------------
2519
2520Added new functions to the e2p library which convert between a string
2521and os_type: e2p_os2string() and e2p_string2os(), and used them to
2522make the generated binaries more compact.
2523
2524Fixed a compile-time error on Darwin systems.
2525
2526Cleaned up the lib/ext2fs Makefile slightly.

Theodore Ts'o3eee5e92005-02-05 18:26:03 -05002529E2fsprogs 1.36 (February 4, 2005)
2530=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002531
2532All of the patches that were applied to Fedore Core 3's
2533e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
2534lot of bug fixes first. Users of Fedora Core 3 are strongly
2535encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
2536
2537Add support for filesystem with the online resizing via resize inode
2538feature. Fixed numerous bugs from the Fedora patches. The Fedora
2539patches also didn't bother to do any consistency checking on the
2540resize inode, or add any tests to the regression test suite. The "-R
2541resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
2542being listed in mke2fs's usage message. All of these shortcomings
2543have been corrected.
2544
2545E2fsck can also also fix filesystems trashed by Fedora's resize2fs
2546program. In order to do this, the user must run the commands:
2547
Theodore Ts'od0a3b462005-05-05 22:57:44 -04002548 debugfs -w /dev/hdXXX -R "features ^resize_inode"
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002549 e2fsck -f /dev/hdXXX
2550
2551Optionally, the ext2prepare command can be used to re-enable online
2552resizing after the filesystem has been fixed.
2553
2554The fsck program will now accept an optional filedescriptor argument
2555to the -C option. (The Fedora version of this patch would sometimes
2556cause fsck to ignore a parameter on fsck's command line in some rare
2557cases, sigh.)
2558
Theodore Ts'odc256972005-01-26 13:20:12 -05002559Make sure e2fsprogs doesn't write garbage into the reserved portion of
2560large inodes.
2561
2562Make sure resize2fs releases the blocks belonging to the old inode
2563table blocks when moving the inode table. (Addresses Debian Bug:
2564#290894)
2565
2566Skip the r_resize_inode test if resize2fs is not compiled (due to
2567configure --disable-resizer)
2568
2569E2fsck now checks the summary filesystem accounting information, and
2570if any of the information is obviously wrong, it will force a full
2571filesystem check. (Addresses Debian Bug #291571)
2572
2573Fix e2fsck to not complain when the resize_inode feature is enabled,
2574s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
2575the resize inode.
2576
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002577Fix e2fsck to note delete symlinks that contain an extended attribute
2578after the ext_attr feature flag has been cleared. (Addresses Red Hat
2579Bugzilla #146284).
2580
Theodore Ts'odc256972005-01-26 13:20:12 -05002581Add new utility program, copy_sparse.c, which is very useful
2582for dealing with large sparse files (such as e2image files).
2583
2584Add support for jnl_blocks[] for debugfs's set_super_value.
2585
2586Fix filefrag so that it works correctly with sparse files.
2587
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05002588Filefrag -v will print first and last blocks.
2589
Theodore Ts'odc256972005-01-26 13:20:12 -05002590Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
2591and dumpe2fs.
2592
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002593Add mke2fs support so that it can support filesystems larger than 4TB
2594automatically, by retrying with a 4k blocksize if the device size is
2595too big to be expressed using a 1k blocksize. (Addresses Sourceforge
2596bug #1106631)
2597
Theodore Ts'odc256972005-01-26 13:20:12 -05002598Change blkid to test for NTFS first because Windows sometimes doesn't
2599clear enough of the parition to confuse the probing routines into
2600thinking the old filesystem type is still valid. (Addresses Debian
2601Bug #291990)
2602
Theodore Ts'o66fa0de2005-01-11 14:39:55 -05002603Add support for swap partition label and uuid's in the blkid library.
2604
Theodore Ts'odc256972005-01-26 13:20:12 -05002605Add support to the blkid library to recognize Oracle ASM volumes.
2606
2607Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002608not just the first one, and work more consistently when the blkid
2609cache file is not available or set to /dev/null. (Addresses Debian
2610Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -05002611
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002612Badblocks will now correctly display block numbers greater than
2613999,999,999 in its progress display.
2614
2615The tune2fs program will not allow the user from setting a ridiculous
2616number of reserved blocks which would cause e2fsck to assume the
2617superblock was corrupt. E2fsck's standards for what is a ridiculous
2618number of reserved block has also been relaxed to 50% of the blocks in
2619the filesystem.
2620
2621The blkid library will return vfat in preference to msdos, and ext3 in
2622preference to ext2 (if the journalling flag is set) so that mount will
2623do the right thing. (Addresses Debian bug #287455)
2624
2625Mke2fs will now use the -E option for extended options; the old -R
2626(raid options) option is still accepted for backwards compatibility.
2627Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
2628
2629Mke2fs will now accept a size in megabytes, gigabytes, and other units
2630(via "32m" or "4g" on the command line) if the user finds this more
2631convenient than specifying a block count.
2632
2633Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
2634cache conherency problem.
2635
2636Debugfs now supports a new command, set_inode_field, which allows a
2637user to manually set a specific inode field more conveniently, as well
2638as set entries in the indirect block map.
2639
2640Debugfs's set_super_value command has been enhanced so that the user
2641can set most superblock fields, including the date/time fields and
2642some of the more newsly added superblock fields.
2643
2644E2fsprogs programs now accept an offset to be passed to the file
2645specifiers, via the syntax: "/tmp/test.img?offset=1024".
2646
2647E2fsprogs programs will now accept blocksizes up to 65536; kernel
2648support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002649other architectures with page sizes greater than 4k. There are 2.6
2650kernel patches out there which enable this, but they are of this
2651writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002652
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05002653The e2image command now takes the -s option which will scramble
2654directory entries for raw image files.
2655
2656Fix a file descriptor leak in the filefrag program.
2657
2658Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
2659present.
2660
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002661Fix bug in debugfs where kill_file would lead to errors when deleting
2662devices and symlinks. (Sourceforge Bugs #954741 and #957244)
2663
2664Fix bug in the blkid library when detecting the ocfs1 filesystem
2665
2666Remove obsolete EVMS 1.x and a.out DLL support.
2667
2668E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -04002669
2670Fixed two potential ordering constraint problems in e2fsck which might
2671cause the filesystem to be corrupted if e2fsck is interrupted during a
2672(extremely narrow) race window. Thanks to Junfeng Yang from the
2673Stanford Metacompilation group for pointing this out.
2674
2675Fixed bug in e2fsck where it would not accurately detect whether or
2676not the system is running on adaptor if the ACPI device representing
2677the AC adapter didn't correspond to the what was used on IBM
2678Thinkpads.
2679
2680Change e2fsck to accept directories greater than 32MB.
2681
2682Fix e2fsck so that a checkinterval of zero disables a time-based check
2683of the filesystem.
2684
2685Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
2686to the PAGER environment variable. (Addresses Debian Bug #239547)
2687
2688Tune2fs will not mark rewrite the superblock if the feature bitmasks
2689are not modified.
2690
2691The debugfs program will set the filetype information when creating a
2692link.
2693
2694Add debugfs -d option to use a separate source of data blocks when
2695reading from an e2image file.
2696
2697Add e2image -I option which allows the e2image metadata to be
2698installed into a filesystem.
2699
2700Fixed bug in the badblocks program which caused "done" to always
2701appear in english even when a translation was available. (Addresses
2702Debian Bug #252836)
2703
2704The blkid program has a new option -o which controls the output format
2705of the blkid program; this is makes blkid more convenient to use in
2706shell scripts.
2707
2708Fix a minor bug in uuid library, which was not using the full 14 bits
2709of clock sequence when generating UUID's.
2710
2711Fix a Y8.8888K problem in the uuid library.
2712
2713Logsave now creates a new session id for itself to avoid getting
2714killed by init whan transitioning between init levels.
2715
2716Change the licensing of the UUID library to be the 3-clause BSD-style
2717license; this allows Apple to use the uuid library in Darwin.
2718
2719Add ocfs and ocfs2 probe support into the blkid library.
2720
2721Fix a memory and file descriptor leak in the blkid library.
2722
2723The blkid library will revalidate the device if the system time is
2724earlier than last verification time of the device, since that
2725indicates that the system time is probably nottrustworthy.
2726
2727The blkid library will override the default location of the blkid.tab
2728file by the BLKID_FILE environment variable, if it is available.
2729
2730Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
2731
2732Add various portability fixes for lame new versions of glibc, Darwin
2733and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002734Bugs #239934, #264630, #269044, #255589, #289133)
2735
2736Add support for Windows 9x/NT under Cygwin.
Theodore Ts'o48301122004-09-19 08:23:41 -04002737
2738Updated and clarified various man pages. (Addresses Debian Bugs #236383,

Theodore Ts'o48301122004-09-19 08:23:41 -04002740
2741Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
2742
2743Update the rpm spec files so that it works better with Fedora core 2
2744and RH9.
2745
2746Fixed various Debian packaging issues (see debian/changelog). In
2747particular, fixed the Debian initrd scripts. (#241183, #248050,
2748#253595, #247775)

2751Programmer's notes:
2752-------------------
2753
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002754Fixed various gcc -Wall warnings.
Theodore Ts'o48301122004-09-19 08:23:41 -04002755
2756The uuid library now has new functions uuid_unparse_upper() and
2757uuid_unparse_lower() which forces the case of the hex digits to be
2758upper case, or lower case.
2759
2760The build process has been speeded up by enhancing the subst program
2761to update the modtime on the generated files even when the generated
2762file hasn't changed.
2763
2764The uuid library now uses C99 stdint.h types instead of custom types.
2765
2766Updated config.guess and config.sub with newer versions from the FSF.
2767
2768Removed out of date .cvsignore files from the source distribution.
2769
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002770The ext2fs_unlink() function will return an error if both the name and
2771inode number are unspecified, to avoid doing something surprising
2772(such as unconditionally deleting the first directory entry).
2773Directory entries are now deleted by coalescing them with the previous
2774directory entry if possible, to avoid directory fragmentation. This
2775is not an issue with the e2fsprogs suite, but may be a problem for
2776some of the users of libext2fs, such as e2tools.
2777
2778Add support for version numbers of the form "1.36-rc1".
2779
Theodore Ts'o48301122004-09-19 08:23:41 -04002780Fix build of mke2fs.static.
2781
Theodore Ts'odc256972005-01-26 13:20:12 -05002782Add basic ext2fs library support for large (EA in inode) inodes.
2783
Theodore Ts'o48301122004-09-19 08:23:41 -04002784The test_io mechanism can now abort after n reads or writes to a
2785particular block. The block is specified by TEST_IO_BLOCK environment
2786variable, and the read/write count by the TEST_IO_READ_ABORT and
2787TEST_IO_WRITE_ABORT environment variables. The block data is now only
2788dumped if the 0x10 bit is set in TEST_IO_FLAGS.
2789
2790UUID_DEFINE() in the uuid library now creates a static variable, with
2791__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
2792be used in header files.
2793
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002794Add support for the install-strip and install-shlibs-strip targets, as
2795suggested by the GNU coding guielines. "make install" no longer
2796strips the binaries which are installed.
2797
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05002798Remove support for the --enable-old-bitops configure option which was
2799only for very old sparc systems.
2800
2801Remove support for --enable-clear-htree; this was only needed during
2802the early development of the htree patch.
2803
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002804Use Linux-kernel-style makefile output so it is easier to see compiler
2805warnings.
2806
2807Update gettext files to version 0.14.1.
2808
2809Update to use autoconf 2.5x.
2810
2811Improved support for compiling e2fsprogs under dietlibc.
2812
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05002813Make e2fsprogs portable to Solaris and FreeBSD systems.
2814
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002815Add blkid_verify(), blkid_get_library_version(), and
2816blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -05002817
2818Add pkg-config files for e2fsprogs's libraries.
2819
2820Fix "make uninstall" to so that it removes everything that is installed.
2821
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05002822Add a configure --enable-maintainer-mode option which enables the
2823makefile rules to rebuild the configure script from configure.in, and
2824to reubuild the .gmo files in po directory.
2825
2826Drop the sparc assembly bitwise operations; it's less efficient
2827than the GCC 3.4 compile code and triggers compiler warnings on
2828sparc64. Thanks to Matthias Andree for his analysis and suggestions.

Theodore Ts'ob70b1162004-02-28 10:52:35 -05002832E2fsprogs 1.35 (February 28, 2004)
2833==================================
2834
Theodore Ts'o48301122004-09-19 08:23:41 -04002835E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -05002836preserves the existing badblocks list.
2837
Theodore Ts'o48301122004-09-19 08:23:41 -04002838Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -05002839
2840E2fsprogs will now deal correctly with symlinks that contain
2841extended attribute information, which can be created using SE Linux.
2842(Addresses Debian Bug #232328)
2843
2844Remove a double longjump into an invalid stack frame bug in e2fsck.
2845(This was during an abort sequence, which normally worked on Linux and
2846caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002847
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002848Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
2849(the NLS library will replace "" with the .po header information).
2850
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002851Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
2852dump due to a division by zero error. (Addresses Debian bug #207082)
2853
Theodore Ts'o151a7162003-12-26 14:04:33 -05002854Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
2855when reconnecting a directory requires creating a lost+found
2856directory. (Addresses Debian bug #219640).
2857
2858Fixed a bug where e2fsck would bomb out if a journal needed to be
2859replayed when using an alternate superblock.
2860
Theodore Ts'o48301122004-09-19 08:23:41 -04002861E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002862if the laptop is running on battery. The next time fsck runs while
2863the system is on the AC mains, or after the grace period is exceeded,
2864the filesystem will be checked. (Addresses Debian bug #205177)
2865
2866E2fsck will inform the user when there are 5 or fewer mounts before a
2867filesystem check will be forced. (Addresses Debian bug #157194)
2868
2869Fix e2fsck's handling of corrupted indirect blocks in the bad block.
2870We now correctly handle the case where there is an overlap between a
2871block group descriptor or a superblock and a bad block indirect block.
2872In the case where the indirect block is corrupted, we now suggest
2873"e2fsck -c".
2874
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002875Fix byte swap bugs in e2fsck that caused the journal backup location
2876in the superblock and symlinks created by SE Linux to be cleared
2877by e2fsck on big-endian machines. (Addresses Debian bug #228723)
2878
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002879E2fsck -c now replaces the current list of bad blocks with the ones
2880found by badblocks.
2881
2882Fix bugs in e2fsck and tune2fs which could cause a core dump if a
2883non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
2884
2885Fix a potential bug in e2fsck which could cause it to core dump when
2886trying to print the location of the backup superblock.
2887
2888Protect against a potential core dump in e2fsck when printing a
2889message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04002890
Theodore Ts'o6826bde2003-08-21 02:14:44 -04002891Add support for backing up the journal inode location in the
2892superblock. E2fsck will automatically save the journal information in
2893the superblock if it is not there already, and will use it if the
2894journal inode appears to be corrupted. ext2fs_add_journal_inode()
2895will also save the backup information, so that new filesystems created
2896by mke2fs and filesystems that have journals added via tune2fs will
2897also have journal location written to the superblock as well.
2898Debugfs's logdump command has been enhanced so that it can use the
2899journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002900
2901E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -04002902
2903Shrink the size of the e2fsck executable by moving some initialized
2904variables to the BSS segment.
2905
2906E2fsck will avoid printing the ^A and ^B characters which bracket the
2907progress bar when stdout and stdin are a tty device instead of a pipe
2908to another program. (Addresses Debian bug #204137)
2909
Theodore Ts'o151a7162003-12-26 14:04:33 -05002910Debugfs's mkdir command will automatically expand the directory if
2911necessary. (Addresses Debian Bug: #217892)
2912
2913Fixed a bug in debugfs so that copying a file from /dev/null uses the
2914correct mode bits. (Addresses Debian Bug: #217456)
2915
2916If the environment variables DEBUFS_PAGER and PAGER are not set,
2917debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -05002918/usr/bin/pager, and then falling back to 'more' and 'less'.

Theodore Ts'ob70b1162004-02-28 10:52:35 -05002921Debugfs will now support 2.6 device numbers where the major or minor
2922number may be larger than 255. (Addresses Sourceforge bug #865289)
2923
Theodore Ts'o48301122004-09-19 08:23:41 -04002924Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
2925
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002926Chattr now stops processing options when it sees '--'. (Addresses

2930with configure --disable-htree.
2931
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002932Fix bug in uuid library when there is no network card and the library
2933is generating a time-based uuid. The random MAC address was not
2934correctly generated to be a multicast address.
2935
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04002936Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -04002937around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04002938
2939Fix bug in badblocks when using O_DIRECT; we need to make sure that
2940we're reading from an offset which is page aligned. For read-only and
2941read-write tests, we try to recover after an error so that we can
2942continue reading on page-aligned boundaries. (Addresses Debian Bug

2955Programmer's notes:
2956-------------------
2957
Theodore Ts'ob70b1162004-02-28 10:52:35 -05002958Fixed a build problem so that e2fsprogs would compile with the
2959--enable-profile option to configure selected. (Addresses Sourceforge
2960bug #811408)
2961
2962Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
2963Bugzilla Bug #112448)
2964
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002965Centralize code which calculates the location of the superblock
2966and block group descriptors so that it is in a single library routine.
2967
Theodore Ts'o6826bde2003-08-21 02:14:44 -04002968Added two new functions, ext2fs_file_open2() and
2969ext2fs_inode_io_intern2() which take a pointer to an inode structure.
2970
2971Fix compile_et to output the correct prototype for
2972initialize_xxx_err_table_r() in the header file. (Addresses Debian
2973bug #204332)
2974
2975In the lib/et makefile, make sure com_err.info is deleted on "make clean".
2976
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04002977Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
2978present. This is for when we try stuffing an int into void * pointer.
2979
2980Fix type-punning which can cause gcc 3.x to miscompile code by getting
2981confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
2982and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
2983**'. The EVMS code uses an ugly union approach since we don't want to
2984modify the EVMS interfaces.
2985
2986Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
2987aid build process on systems can use invoke GNU make as "gmake".
2988
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002989Added regression testing for mke2fs.
2990
2991Fixed gcc -Wall nitpicks.
2992
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002993Fixed various compiler warnings.
2994
2995Add portability fixes for FreeBSD and for using fsctl under Darwin to
2996support ext2 ioctl's.
2997
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04002998
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04002999E2fsprogs 1.34 (July 25, 2003)
3000===============================
3001
3002Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
3003a tight loop while waiting for a child fsck to exit in some cases.
3004This burns CPU times which slows down the low-level filesystem check.
3005
3006Added code to mke2fs to assure that the default block size for a
3007filesystem is at least as big as the sector size of the device, if it
3008can be determined.
3009
3010Changed mke2fs and resize2fs to round the default size of a filesystem
3011to be an even multiple of the VM pagesize in order to avoid a Linux
3012kernel bug introduced when the storage of the buffer cache was moved
3013into the page cache.
3014
3015Mke2fs will warn the user when creating a filesystem with journaling
3016and a blocksize greater than 4096. (Addresses Debian bug #193773)
3017
3018Fixed a bug in resize2fs which caused it to fail on filesystems with a
3019non-empty bad block list. Resize2fs now discards any blocks on the
3020badblock list which are no longer part of the filesystem as the result
3021of a filesystem shrink. (Note: this means that shrinking and then
3022enlarging a filesystem is no longer a reversible operation;
3023information about bad blocks in the part of the filesystem which is to
3024be chopped off will be lost.)
3025
3026Changed resize2fs so the user can use prefixes to specify the units of
3027the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
3028and to make the error and informational messages explicitly display
3029the blocksize used by the filesystem, in order to avoid confusion.
3030(Addresses Debian bug: #189814)
3031
3032Added a new debugfs command, dump_unused, which dumps the contents of
3033all unused blocks to stdout. (Useful as an emergency try-to-find
3034deleted data command.)
3035
3036Added a new debugfs command, imap, which prints the location of a
3037specified inode in the inode table.
3038
3039Fixed a bug in the badblocks program which caused it to use one bit of
3040randomness in its non-destructive read/write test, instead of using a
3041full 8 bits of randomness.
3042
3043Added a new option (-t) to badblocks, which allows the user to control
3044the test pattern(s) used when checking a disk.
3045
3046The blkid probe function now more correctly detects UDF filesystems.
3047
3048Fixed a bug in the blkid library which caused it to not update its
3049cache if a filesystem changes from having a label to not having a
3050label.
3051
3052Fixed a bug in the blkid library wihch could avoid an infinite loop
3053in blkid_find_dev_with_tag() if /proc is not mounted and there the
3054/etc/blkid.tab file has not yet been created.
3055
3056Fixed the badblocks program so that the destructive read/write test
3057honors the -c option, and to use O_DIRECT when possible to avoid
3058thrashing the system block buffer cache.
3059
3060Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -04003061 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04003062 - Removed testing NYC translation
3063 - Fixed NLS support for message abbrevations in e2fsck
3064 - Remove de-utf.po, since we shouldn't have two versions using different
3065 charset encodings.
3066 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
3067 simplify the statistics reporting in e2fsck.
3068
3069Changed configure.in so that its defaults for *BSD systems no longer
3070build an fsck wrapper, and not to install in /usr/local by default.
3071
3072Fixed some minor spelling errors/typo's in e2fsck and the configure
3073script.
3074
3075Fixed various Debian packaging issues (see debian/changelog).
3076
3077Updated and clarified man pages. (Addresses Debian Bug #195616)
3078
3079Programmer's notes:
3080-------------------
3081
3082Fix gcc -Wall nitpicks.
3083
3084Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
3085NLS support by default. (Added partial workaround for gettext/Darwin
3086incompatibility problems.)
3087
3088Added full MIT KRB5 and Himdall compaibility support to the com_err
3089library and the compile_et program. (Addresses Debian bug #191900)
3090
3091Added the blkid_known_fstype() function to the blkid library, which
3092returns true if it is passed a filesystem type which is recognized by
3093the blkid probing functions.
3094
3095Improved the documentation for the blkid library.
3096
3097Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
3098returns the hardware sector size of a device, if it is available.
3099
3100Added a dependency in the blkid library's .so file to the uuid
3101library, since the former uses the latter. (Addresses Debian bug
3102#194094)
3103
3104Added --with-diet-libc and --disable-evms to the configure script.
3105
3106Fixed a minor memory leak in the badblocks program.
3107
3108Fixed a portability problem in tune2fs --- not all systems have strptime().
3109
3110Fixed a portability problem in debugfs with the use of getopt() more
3111than once. Old-style BSD, new-style BSD, and Linux C libraries all do
3112things differently.
3113
3114Add support Windows support to ext2fs_get_device_size().
3115
3116Added (normally disabled) debugging code to the Unix I/O manager which
3117causes it to disable all userspace caching if the NO_IO_CACHE is
3118defined.
3119
3120Changed the test I/O manager so it can always be linked into e2fsck,
3121mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
3122configure script. The test I/O manager will only print any debugging
3123information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
3124variables are set, which specifies which I/O operations are logged and
3125a block number to watch, respectively. The log messages are sent to
3126stderr by default, unless a filename is specified via the
3127TEST_IO_LOGFILE environment variable.
3128
3129
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04003130E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04003131===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -05003132
Theodore Ts'oba142c12003-04-16 00:59:59 -04003133Added a new utility program, logsave, which captures the output of a
3134command in a log file, even if the containing directory hasn't been
3135mounted yet (in which case the it saves the output in memory until it
3136can write out the logfile). This is useful for capturing the
3137output of fsck during the boot sequence.
3138
3139Fixed some portability problems that were causing problems under
3140the Cygwin32 environment.
3141
3142Mke2fs now interprets a negative number to the -b option as a minimum
3143block size.
3144
3145Fixed a bug in mke2fs which was incorrectly checking the argument to
3146the -g option if the default block size was used. (Addresses Debian
3147bug #188319)
3148
3149Fsck now explicitly ignores tmpfs and devpts, and it will complain if
3150it can not find filesystem checkers for jfs, reseirfs, and xfs.
3151
3152E2fsck now updates the global free block and inode counters from the
3153block group specific counters quietly. This is needed for an
3154experimental patch which eliminates locking the entire filesystem when
3155allocating blocks or inodes; if the filesystem is not unmounted
3156cleanly, the global counts may not be accurate.
3157
3158Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
31592.0 is not yet supported; this only pulled in the bug fixes: fixed
3160possible hangs caused by bugs in calling waitpid, and not setting the
3161pipe to non-blocking mode; also fixed a file descriptor leak; made
3162sure all functions call log entry/exit functions.)
3163
3164Badblocks now flushes its output file as bad blocks are discovered.
3165
3166The uuid library is now more paranoid about assuming the correctness
3167of the /dev/random device; it mixes in a stream of bytes from
3168random/srandom, just in case.
3169
Theodore Ts'o39d38b02003-03-30 23:45:02 -05003170Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04003171maintainer of e2fsprogs. Other various Debian-specific packaging
3172cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05003173
3174Move the source tarball generation functions from the top-level
3175makefile to the util/gen-tarball script.
3176
3177Updated the Turkish .po translation file.
3178
Theodore Ts'o1daf7582004-01-31 22:33:16 -05003179Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05003180it more compatible with com_err libraries from those distributions.
3181
3182Changed dumpe2fs to always display the superblock fields relating to
3183the journalling and/or directory indexing feature even if those
3184features are not enabled.
3185
Theodore Ts'o508d7f32003-03-16 20:41:04 -05003186Updated and clarify copyright statement vis-a-vis alpha releases of
3187e2fsprogs.
3188
3189The ss library will now try to dynamically link to the readline
3190library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04003191the debugfs program now has line editing and history features. The
3192SS_READLINE_PATH environment variable is used to find a readline or
3193readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003194
Theodore Ts'oe5dced72003-03-15 04:28:17 -05003195E2fsck now finds most duplicate filenames (all when rebuilding all
3196directories via the -D option) and offers to delete or rename
3197duplicate filenames/directory entries. (Addresses Debian Bug #176814).
3198
3199Fix bug in e2image. When writing out a raw image file, include data
3200blocks from symlinks that do not store the symlink within the inode.
3201
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003202Fix bug in resize2fs which incorrectly moved the block and inode
3203bitmaps for sparse superblock filesystems and incorrectly marked
3204blocks as in use. (Addresses Debian bug #174766)
3205
3206Added a new shared library, the blkid library, which efficiently
3207allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
3208and UUID filesystem specifiers without needing to search all of the
3209devices in the system. Instead, the device is looked up in a cache
3210file, and then verified to make sure the blkid cache is correct.
3211
3212Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
3213the device name, using the blkid library. (Addresses Debian bugs
3214#166048, #179671)
3215
3216Fsck now supports backslash escapes in /etc/fstab so that \040 can be
3217used for spaces in device labels.
3218
3219Removed 32-bit limitations for debugfs's dump command.
3220
3221If the user specifies a large number of inodes, Mke2fs will
3222automatically adjust the number of blocks per group to find a valid
3223set of filesystem parameters.
3224
3225Add workaround to detect broken MD devices where when some of the
3226underlying devices are marked read-only, writes to the MD device are
3227silently dropped. E2fsck will detect if there is an attempt to run
3228the journal twice, and abort with an error if this is the case.
3229(Addresses IBM Bugzilla bug #1226)
3230
3231E2fsck will print an error if more than one of the -p/-a, -n or -y
3232options are specified.
3233
3234E2fsck will fix HTREE corruptions in preen mode, without stopping the
3235boot process. This is needed because the 2.4 ext2 filesystem
3236accidentally had the INDEX_FL backwards compatibility code removed.
3237
3238Mke2fs no longer creates filesystems with the dir_index flag set by
3239default; the user has to specifically request it.
3240
3241Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04003242#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003243
Theodore Ts'o508d7f32003-03-16 20:41:04 -05003244Created man page for the mk_cmds program (from the libss library).
3245
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003246Programmer's notes:
3247-------------------
3248
3249Fix various gcc -Wall nits.
3250
3251Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05003252successfully under Solaris and Apple/Darwin.
3253
3254Fixed a Makefile dependency to allow building e2fsprogs using parallel
3255make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003256
3257Changes to create a subset distribution which consists only of the
3258et, ss, uuid, and blkid libraries. The configure script and top-level
3259makefile were changed to support working with a subset distribution.
3260
Theodore Ts'oba142c12003-04-16 00:59:59 -04003261Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
3262actually used, and might people who are looking for
3263EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
3264
Theodore Ts'o508d7f32003-03-16 20:41:04 -05003265Updated debian files to fix a number of Lintian warnings.
3266
3267Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003268
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04003269Removed unnecessary libraries from being linked into the fsck, lsattr,
3270chattr, and blkid executables.
3271
Theodore Ts'o38513012002-11-09 15:00:56 -05003272E2fsprogs 1.32 (Nomvember 9, 2002)
3273==================================
3274
3275Fixed a bug in the Unix I/O routines which caused needless writebacks
3276of clean blocks from the unix_io cache (they were erroneously marked
3277as being dirty, so they were getting written back to disk before
3278getting evicted from the disk cache). This was harmless, but it
3279significantly slowed down e2fsck.
3280
3281Made some other minor optimizations to the Unix I/O routines to save a
3282small amount of CPU time.
3283
3284Updated internationalization files.
3285
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003286
Theodore Ts'oae65b292002-11-08 20:08:48 -05003287E2fsprogs 1.31 (Nomvember 8, 2002)
3288==================================
3289
3290Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
3291compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
3292handling for child process that die unexpectly. Add a hack to force
3293mkfs to create filesystems that won't cause problems with hardware
3294that has 2k or 4k minimum blocksize requirements. Read from child
3295processes in non-blocking mode, so that the GUI continues to update.
3296
3297Fix e2fsck so that it returns the appropriate exit code when the root
3298filesystem has been changed, so that system's rc scripts will be told that
3299the system needs to be rebooted.
3300
3301Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
3302was set, some of the descriptor blocks that should have been written
3303out were getting skipped.
3304
3305Changed e2fsck to force out changes to the backup copies of the
3306superblock and block group descriptors when important changes are made
3307to those data structures.
3308
3309Fix a bug where e2fsck could erroneously mark a filesystem as being
3310clean if a check of dirty filesystem is interrupted with a ^C. (Bug
3311introduced in e2fsprogs 1.28.)
3312
3313If journal debuging is enabled using --enable-jbd-debug, the debugging
3314level is now set via the E2FSCK_JBD_DEBUG environment variable.
3315
3316If byteswapping support is disabled using configure --disable-swapfs,
3317skip the tests which depend on byte-swapping, so that "make check"
3318won't bomb out.
3319
3320Lshattr will now display the indexed directory flag. Also, some of
3321the more esoteric compression flags are supressed unless compression
3322support has been enabled.
3323
3324Update man pages.
3325

Theodore Ts'o5d823a42002-11-01 02:13:53 -05003327E2fsprogs 1.30 (October 31, 2002)
3328=================================
3329
3330When resizing a filesystem, and inodes need to moved, resize2fs will
3331update the inode's ctime field, and the mtime field of the containing
3332directories, so that incremental backups using dump/restore will work
3333correctly.
3334
3335In order to avoid spurious errors, e2fsck wil check the last
3336superblock write time to determine whether or not it can safely use
3337the LOW_DTIME checks to determine if there are inodes on the orphan
3338inode linked list that had somehow gotten disconnected. (Addresses
3339Sourceforge bug #620980)
3340
3341Partition in /proc/partitions that being with the string "lvm" are
3342considered real partitions even if they do not end with a number.
3343
3344Fixed a bug in the the uuid generation function, where if /dev/urandom
3345is not present, but /dev/random is, and there isn't sufficient
3346entropy, the get_random_byte function could spin a loop forever.
3347
3348E2fsck, mke2fs, etc. will now reliably notice when image files are
3349mounted using the loopback interface. (Addresses Sourceforge bug
3350#619119)
3351
3352When flushing buffers (as is done by badblocks, for example) check to
3353see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
3354FDFLUSH ioctl which causes the MD device driver which causes confusing
3355syslog messages about obselete ioctl messages. (Addresses Sourceforge
3356bug #545832).
3357
3358Debugfs's write command now checks to see if the destination filename
3359exists before creating it. (Addresses Sourceforge bug #478195.)
3360
3361When installing man pages, search for compressed man pages using all
3362commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
3363
3364Fixed a bug in fsck where multiple filesystems specified on the
3365command were not being checked in parallel due to a logic bug
3366introduced to support the FSCK_MAX_INST environment variable.
3367
3368We have added a new superblock field, s_mkfs_time, which indicates
3369when a filesystem was created. It is set via mke2fs, and printed out
3370by dumpe2fs, but is not actually touched by the kernel.
3371
3372Dumpe2fs has been made more robust by not aborting if there is an
3373error reading the block/inode bitmaps; instead it will still print out
3374the location of the block/inode bitmaps and inode table.
3375
3376Add support for the an alternative block group descriptor layout which
3377allows for on-line resizing without needing to prepare the filesystem
3378in advance. (This is the incomat feature flag meta_bg.)
3379
3380Add support for storing default mount options in the superblock, so
3381that the filesystem can be mounted with specific mount options without
3382needing to specify them on the mount command line or in the /etc/fstab
3383file.
3384
3385Add support for a new inode flag, which is to be used for indicating
3386the top of directory hierarchies for the Orlov block allocator.
3387
3388Fix e2fsck so that if it creates the lost+found directory, it does so
3389with the more apporpriate permissions of 0700. Also change
3390mklost+found so that it also creates the directory 0700.
3391
3392Fixed format bug in e2fsck if NLS is in use.
3393
3394Add a German translation for e2fsprogs's NLS support.
3395
3396Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
3397the beginning of the inode table. This won't matter much, since if
3398there is a bad block at the beginning of the inode table, the root
3399directory won't be available. But at least e2fsck won't crash in this
3400case.
3401
3402Fixed endian problems in the htree code for e2fsck and debugfs.
3403
3404When byte-swapping a filesystem on a PPC architecture, byte-swap the
3405bitmaps since the historical big-endian ext2 variant had byte-swapped
3406bitmaps, and the ext2fs library assumes this. This fixes the
3407regression test suite on PPC machines.
3408
3409Fix e2image so that it handles a bad block in the inode table
3410appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04003411
3412E2fsck now uses a more sophisticated algorithm to salvage corrupted
3413directories that recovers more information in the corrupted directory
3414block.
3415
3416E2fsck now performs additional consistency checks on indexed (HTREE)
3417directories.
3418
3419Fix bug where efsck might get confused about whether a completely
3420empty directory block is an empty leaf block or an interior htree
3421node. This could cause e2fsck to get confused into think that a valid
3422indexed directory was corrupted.
3423
3424E2fsck no longer creates an empty directory entry at the end of a
3425directory block when optimizing a directory. This would cause some
3426earlier versions of the dxdir kernel code to corrupt the directory
3427when attempting to split a node containing an empty directory entry.
3428
3429E2fsck could sometimes in rare circumstances leave the indexed flag
3430set after a small directory was optimized by compressing it instead of
3431indexing it. (This should never happen in real life, since
3432directories that small wouldn't have been indexed, but better safe
3433than sorry.)
3434
3435E2fsck now only updates the master superblock in all cases. This
3436slightly shortens its run time.
3437
3438Ext2ed can deal with directory entries of length 0; previously it
3439would get stuck in an infinite loop.
3440
3441Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
3442specifiers. (Sourceforge patch #613447)
3443
3444Badblocks will now work correctly on read-only devices such as
3445CD-ROM's. (Sourceforge patch #600451)
3446
Theodore Ts'o5d823a42002-11-01 02:13:53 -05003447Updated and clarified man pages. (Addresses Debian bug #167108)

Theodore Ts'oc6633052002-09-24 01:26:50 -04003450E2fsprogs 1.29 (September 24, 2002)
3451===================================
3452
3453Fixed a bug in e2fsck which could corrupt a directory when optimizing
3454it (via the -D option) or rebuiliding the hash tree index with a 1 in
3455512 probability, due to a fence post error.
3456
3457Fixed a bug in the LVM support code which caused LABEL='xxx' not to
3458work correctly.
3459
3460Mke2fs now enables the directory indexing flag by default. (Since
3461this is a compatible feature flag, it's safe to do so.)
3462
3463Tune2fs will support setting the directory indexing feature flag. It
3464will automatically set up the default hash algorithm and hash seed
3465fields in the superblock.
3466
3467If the bone-headed user enters the root filesystem twice in
3468/etc/fstab, the -R option which skips the root filesystem will skip
3469all of them. (Addresses Debian bug #159423). Note! This is not a
3470precedent for dealing intelligently with any other kind of doubled
3471entry in /etc/fstab!
3472
3473
3474Programmer's notes:
3475-------------------
3476
3477Removed perror declaration in lib/et/internal.h. All modern systems
3478can be expected to define perror() these days. Besides, the lib/et
3479code wasn't using perror at all anyway. :-)
3480
3481
Theodore Ts'ob7bad612002-08-31 03:00:33 -04003482E2fsprogs 1.28 (August 31, 2002)
3483================================
3484
3485Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
3486for setting the htree flag is not included yet, although it can be
3487manually turned on via the debugfs program.
3488
3489Clarified e2fsck error message which is printed when it cannot find
3490sufficient contiguous block when relcating filesystem metadata.
3491
3492Added support for building an EVMS plugin module for ext2/3. This
3493module is substantially the same as the EVMS module shipping with EVMS
34941.1, with one or two bugfixes. E2fsprogs can also build this plugin
3495for use with EVMS 1.0 (which did not include the ext2 plugin module),
3496if the configure --enable-old-evms flag is given.
3497
3498Fsck will search through EVMS volumes when trying to resolve
3499filesystem specifications such as LABEL=xxx or UUID=xxx.
3500
3501Added a new utility program, /sbin/findfs, which will return
3502filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
3503the device name.
3504
3505Update and clarified various man pages. (addresses Debian Bug #145044,
3506#146437, #131350, #151990, #144621, #141938)
3507
3508If there are no filesystems specified on fsck's command line, fsck now
3509treat that as if the -As options were given. Previously it would
3510simply do nothing. (Addresses Debian Bug #153102)
3511
3512Mke2fs no longer treats a failure to be able to clear the MD signature
3513at the end of the filesystem as a fatal error. (Addresses Debian Bug
3514#155007)
3515
3516The e2p library functions (which are used by lsattr and chattr) now
3517double check to make sure the file is a regular file or directory
3518before attempting to use the ext2 ioctls. Some device drivers
3519unfortunately respond to the ext2 ioctl's with unknown behaviour.
3520(Addresses Debian Bug #152029).
3521
3522The extended attribute handling has been updated to correspond with
3523the latest V2 bestbits ACL code.
3524
3525Fixed bug in e2fsck which caused it to not clear the dtime field when
3526processing truncated inodes on the orphan list. This could cause data
3527loss(!) if a filesystem is rebooted before a truncate has been
3528committed.
3529
3530E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
3531algorithms. This makes e2fsck much faster in the case of severely
3532corrupted filesystems where a large number of blocks are claimed by a
3533large number of inodes. (Thanks to the 2.5 IDE device driver for
3534inspiring this work.)
3535
3536Resize2fs has been significantly sped up when shrinking and expanding
3537a filesystem by a very small number of blocks (for example, when EVMS
3538is converting a partition to be an EVMS legacy volume).
3539
3540Added a new option to e2fsck, -D, which will optimize or compress all
3541of the directories in the filesystem.
3542
3543E2fsck now catches SIGINT and SIGTERM to make sure it will can
3544properly clean up and only exit at safe points. Fsck will pass
3545SIGINT/SIGTERM to its child processes, and wait until they have all
3546exited before it exits.
3547
3548The uuid parsing code in the uuid library now properly complains when
3549an illegally formated uuid is presented to it. (Addresses Debian bug
3550#152891)
3551
3552Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
3553and 2.4.17, since the workaround can cause problems when using a 2.4
3554kernel with an old version of glibc built with the 2.2 headers.
3555
3556Fixed a bug in mke2fs where it wasn't properly clearing the initial
3557superblock used by other filesystems. (Addresses Debian bug #147256.)
3558
3559Added support for the synchronous directory feature written by Andrew
3560Morton.
3561
3562The debugfs program can delete directories using the rmdir command.
3563
3564Add support for 8k and 16k filesystems (for systems with page sizes
3565that are greater or equal to 8k or 16k, respectively). Note that
3566these filesystems can not be mounted on x86 systems, or other systems
3567with only 4k page sizes, due to limitations in the current Linux VM
3568code.
3569
3570Resize2fs requires that the filesystem state be valid and have no
3571errors; otherwise, e2fsck -f must be run first. (Previously it simply
3572required that the last fsck time be greater than the last mount time.)
3573
3574Configure now defaults the man pages directory to /usr/share/man on
3575Linux systems.
3576
3577E2fsck now offers to truncate inodes which contain too many blocks (so
3578that i_blocks would overflow. Also fixed handling of large sparse
3579files.
3580
3581E2fsck now more completely checks for symlink validity, including
3582requiring NULL termination and length checks.
3583
3584E2fsck will offer to try forcing a disk write to remap a bad block
3585after finding a read error when reading a filesystem metadata block.
3586
3587Fixed a bug in debugfs which caused the -b and -s options to crash
3588debugfs, as well as breaking the testb, setb, and clearb functions.
3589
3590Added a bmap command to debugfs which calculates the logical to
3591physical block mapping for a particular inode.
3592
3593Fixed a bug in code which checked to see if a device was mounted which
3594sometimes (rarely) failed in the case of a plain file.
3595
3596Fixed a bug in resize2fs where when it reported an error, it would
3597print a message erroneously indicating that the filesystem had been
3598resized before it aborted.
3599
3600When resizing a plain file which is smaller than the requested size,
3601resize2fs will attempt to extended the file so that programs like
3602e2fsck will not complain that the file is too small.
3603
3604Resize2fs will print the actual new size of the filesystem when it is
3605finished resizing.
3606
3607Fixed a bug in debugfs where "ls -l" would report incorrectl file type
3608information on big-endian systems.
3609
3610
3611Programmer's notes:
3612-------------------
3613
3614Fixed collisions with C++ reserved words.
3615
3616Added portability fixes for building e2fsprogs on the HURD and AIX.
3617
3618Added the ext2ed program for creation of test cases. (ext2ed has many
3619limitations and bugs which make it unsuitable for production use.)
3620
3621The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
3622flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
3623name_len field is byte swampped on big-endian machines, since in the
3624V2 structure, name_len is a char field which is doesn't need to be
3625byte swapped --- except if an old-style kernel had byte-swapped the
3626name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -05003629E2fsprogs 1.27 (March 8, 2002)
3630==============================
3631
3632The warning messages for mke2fs now go to standard error.
3633
3634Fixed to make sure "make check" runs all of the test programs with
3635LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
3636
3637The mke2fs program checks the boot sector for the BSD disk label, and
3638avoids erasing it if it is there.
3639
3640Fixed a bug in e2fsck which caused it to core dump if the journal
3641inode was missing when it was supposed to be there.
3642
3643E2fsck now prints ranges in pass 5 when printing deltas for the block
3644and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05003645
3646Debugfs's "ls -l" command now will print out the file type information
3647in the directory entry.
3648
3649Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
3650mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
3651
3652Debugfs can now examine the experimental directory indexing
3653information.
3654
Theodore Ts'oa471ac52002-03-05 03:37:06 -05003655Fixed bug in debugfs which caused it to core dump if modify_inode is
3656called without an open filesystem.
3657
3658The debugfs lsdel command now runs its output through a pager first.
3659
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05003660When installing manual pages, remove the compressed manual pages first.
3661
3662Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
3663
3664Fix the 2.4 resource limitation workaround introduced in 1.26 which
3665actually broke things on mips32, sparc32, and Alpha platforms.
3666
Theodore Ts'oa471ac52002-03-05 03:37:06 -05003667Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
3668(which is required by the newer libintl libraries).
3669
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05003670Programmer's notes:
3671-------------------
3672
Theodore Ts'oa8e77242002-03-08 03:12:14 -05003673Fixed various gcc -Wall complaints.
3674
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05003675Fixed a few memory leaks in the e2fsck journaling code, and in the
3676ismounted code checking for a swap device.
3677
3678Add new inode I/O abstraction interface which exports an inode as
3679an I/O object.
3680
3681Exported ext2_file_flush as a public interface.
3682
3683In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
3684
3685Lots of small random portability fixes to make e2fsprogs build under
3686AIX --- even without the 5L compatibility toolkit, and even using the
3687uber-crippled AIX native C compiler.

Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003691=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003692
Theodore Ts'o446314f2001-12-24 15:22:27 -05003693Dumpe2fs will keep going now if the bad block inode can't be read.
3694(Previously it stopped with a fatal error.)
3695
3696E2fsck will now give an opportunity to run the journal even if the
3697recovery flag is not set. This is the default behaviour if e2fsck is
3698using a backup superblock, since the needs_recovery flag will never be
3699set in the backup superblock copies.
3700
3701E2fsck now automatically finds the backup superblock/group descriptors
3702even when the primary superblock is completely destroyed for 2k and 4k
3703filesystems. (Previously it just guessed/assumed that we were dealing
3704with a 1k filesystem in that case, and users had to manually specify
3705the backup superblock number.)
3706
3707Fixed a bug in e2fsck where it dereferences a null pointer when there
3708is a problem opening a filesystem in preen mode.
3709
3710E2fsck now handles external journals correctly; previously it trashed
3711the external journal device if the journal needed to be replayed.
3712
3713Work around ulimit incompatibility problem caused by recent 2.4
3714kernels; the unix IO module will automatically try to set any resource
3715limits to be infinite on startup.
3716
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003717Fixed a bug in e2fsck where it wasn't allocating a new block or inode
3718bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04003719 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003720
3721E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
3722clearing the new V2 fields if they do not make sense or if the ext3
3723superblock is version 1 superblock.
3724
3725E2fsck will automatically relocate the ext3 journal from a visible
3726file (i.e., /.journal) to an hidden inode if the filesystem has been
3727opened read/write. This allows the users to add a journal while the
3728filesystem is mounted, but the next time the system is rebooted, the
3729journal file will disappear. This avoids problems with backups,
3730stupid operators with superuser bits, etc.
3731
3732Fix a bug in fsck where it would not support a filesystem type of
3733"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
3734
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003735Fsck now supports fstab entries of the form "ext3,ext2". It will also
3736automatically identify reiserfs filesystems.
3737
3738The number of processes spawned by fsck can now be limited using the
3739FSCK_MAX_INST environment variable.
3740
Theodore Ts'o446314f2001-12-24 15:22:27 -05003741Fsck now searchs the LVM proc hierarchy to find logical volumes which
3742should be searched for UUID and label information.
3743
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003744Work around a bug in 2.4.10+ kernels by trying to unset the filesize
3745limit if at all possible, when opening a block device. (The filesize
3746limit shouldn't be applied against writes to a block device.)
3747
Theodore Ts'o446314f2001-12-24 15:22:27 -05003748In mke2fs and e2fsck, specifying the -c option twice will now do
3749a read/write test on the disk. Update the man pages to encourage
3750using the -c option, and to discouraging running badblocks separately,
3751since users tend to forget to set the blocksize when running
3752badblocks.
3753
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003754Mke2fs now automatically clears the immutable attribute on a
3755pre-existing .journal file left over from a previous failed attempt to
3756add a journal to an alreadyy-mounted filesystem.
3757
3758Fixed mke2fs's exit codes to consistently indicate when the mke2fs
3759operation failed.
3760
Theodore Ts'o446314f2001-12-24 15:22:27 -05003761Mke2fs now creates the lost+found directory with permissions of 0700,
3762so that files that had previously lived in protected directory are
3763safe if they get dropped in lost+found and the system administrator
3764doesn't deal with immediately. (Addresses Debian #bug 118443)
3765
3766Mke2fs and e2fsck (and all programs that use the
3767ext2fs_check_if_mounted function) will now properly identify that a
3768device is mounted, even in cases where devfs has confused things with
3769multiple devices names with the same identity, or if a dim-witted
3770system administrator has done something stupid like creating device
3771file aliases in their home directory. Also now checks for swap devices
3772by using /proc/swaps. (Addresses Debian bug #106622)
3773
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003774Added a new option (-T) to tune2fs which sets the time a filesystem
3775was last checked.
3776
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003777Speed up e2image when creating sparse raw image files by optimizing
3778away excess lseek() system calls.
3779
3780Fix support of large (> 2GB) files when used as a filesystem in
3781mke2fs, tune2fs, debugfs, and findsuper.
3782
3783Debugfs's stat and icheck commands now properly deals with large (>
37842GB) files.
3785
3786Debugfs's set_super_value command now prints out the list of valid
3787superblock fields which can be set using the command.
3788
Theodore Ts'o446314f2001-12-24 15:22:27 -05003789Debugfs's rm and kill_file command now updates the superblock free block
3790and inode counts, thus keeping the filesystem consistent.
3791
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003792Debugfs's lsdel command now takes an optional argument which allows
3793the user to only see the most recently deleted files.
3794
3795A new command (undel) was added to debugfs which automates
3796undeleting a deleted inode and linking it back to a directory.
3797
3798Debugfs's ls command now takes a new option, -d, which lists
3799deleted directory entries.
3800
3801Debugfs's testb, freeb, setb, and find_free_block commands now take an
3802optional count argument.
3803
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003804Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
3805be used to signal that a particular inode should not be eligible for
3806tail-merging --- this is needed for programs like LILO.
3807
3808The findsuper (an unreleased, uninstalled utility program) has been
3809improved to add extra validity checks and to add a progress meter.
3810(It is still an unsupported program; the officially supported way to
3811recover from a trashed partition table is to use gpart; findsuper is
3812for wizards only. :-)
3813
3814Debugfs was fixed to compile with "configure --disable-swapfs".
3815
Theodore Ts'o446314f2001-12-24 15:22:27 -05003816Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003817
3818Added new translation file for Turkish.
3819
Theodore Ts'o446314f2001-12-24 15:22:27 -05003820Programmer's notes:
3821-------------------
3822
3823Fix general gcc -Wall complaints.
3824
3825E2fsprogs (mostly) works with the dietlibc.
3826
3827The programming texinfo file has been expanded to include description
3828of additional libext2fs functions. (Still not compeltely done, but a
3829lot of the more important functions have been documented.)
3830
3831Added a umask structure to struct_ext2_filsys, which currently only
3832modifies the behaviour of ext2fs_mkdir(), but if we add any file
3833creation functions to libext2fs, we should also make sure they respect
3834the umask setting.
3835
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003836The build-rpm script was fixed to be a bit more safe.
3837
3838The tests' Makefile now has a way of automating test case creation
3839for e2fsck, using "make testnew".
3840
3841Created a new function, ext2fs_dir_iterate2 which passes more
3842information to the callback function (identical to the one used by
3843ext2fs_dblist_dir_iterate). The directory iterator functions take a
3844new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
3845directory entries. If the directory entry is deleted, the callback
3846function will be called with the entry paraemter set to
3847DIRENT_DELETED_FILE.
3848
3849Added new functions, ext2fs_inode_alloc_stats and
3850ext2fs_block_alloc_stats, which takes updates block/inode allocation
3851statistics in the bitmaps, block group descriptors, and superblock
3852when inodes or blocks are allocated or deallocated.
3853

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04003855E2fsprogs 1.25 (September 20, 2001)
3856===================================
3857
3858This is primarily a bug-fix release; no new features were added, but
3859there are a number of embarassing bug fixes and cleanups applied.
3860
3861Fix a bug mke2fs which causes stack garbage to be written to disk when
3862zapping disk sectors. (This bug could cause mke2fs to core dump for
3863some kernels, I suspect with security enhancement patches.)
3864
3865Remove unneeded #include of <linux/config.h> which was breaking
3866building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
3867
3868Updated tune2fs man page to reflect the fact that adding or removing a
3869journal doesn't require running e2fsck.
3870
3871Remove use of AC_REQUIRE from autoconf which had been used to prevent
3872AC_CANONICAL_HOST from being called twice; unfortunately this causes
3873recent autoconf to bomb out since they don't allow AC_REQUIRE to be
3874used outside of autoconf macros. Fortunately, it doesn't seem to be
3875necessary any more, anyway.
3876
3877E2fsck will now not fall back to an alternate superblock if the user
3878specifies the superblock location explicitly on the command-line.
3879This allows easier recovery from a situation where the primary
3880superblock and block groups are slightly corrupted, but the backup
3881superblocks are completely broken.
3882
3883Fix problem which caused compile_et and mk_cmds to blow up if
3884e2fsprogs was in a directory with a pathname that contained spaces.
3885
3886We are now more paranoid about checking the entry in /etc/mtab to make
3887sure the filesystem is really mounted, since some broken distributions
3888(read: Slackware) don't initialize /etc/mtab before checking non-root
3889filesystems. (Slackware also doesn't check the root filesystem
3890separately, and reboot if the root filesystem had changes applied to
3891it, which is dangerous and broken, but there's nothing I can do about
3892that.)
3893
3894Make UUID library C++ friendly by adding appropriate extern "C"
3895declarations and using const in the function declarations.
3896
3897Fix up the com_err texinfo file so that it can product a valid info
3898file (previously, it could only be used to generate paper
3899documentation using texinfo.tex).
3900
3901
Theodore Ts'ofb707752001-09-04 15:00:37 -04003902E2fsprogs 1.24a (September 2, 2001)
3903===================================
3904
3905Fix brown-paper bug in mke2fs which caused it to segfault when
3906printing the version string.
3907
3908
Theodore Ts'o109624a2001-08-31 00:59:55 -04003909E2fsprogs 1.24 (August 30, 2001)
3910================================
3911
3912Revert the BLKGETSIZE64 support, since for some distributions, this
3913ioctl has been used by an unofficial kernel patch to update the last
3914sector on the disk, and this was causing disk corruption problems as a
3915result.
3916
3917Mke2fs is now more careful about zapping swap space signatures and
3918other filesystem/raid superblock magic values so that programs like
3919mount who try to use hueristics to determine the filesystem type of a
3920partition are less likely to be confused.
3921
3922E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
3923regular file (since Andreas Dilger's on-line resizing tools will set
3924its mode bits).
3925
3926Fixed some minor texinfo, man pages nits for spelling errors,
3927texinfo warnings, etc. (Addresses Debian bug #110621.)
3928
3929E2fsprogs program no longer print the filesystem version number
3930(i.e. 0.5b), since it only confuses people and doesn't serve any real
3931purpose.
3932
3933E2fsck will once again compile under libc5, since it will supply its
3934own version of strnlen if necesssary.
3935
3936mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
3937when specifying the external journal device. tune2fs will also search
3938devices looking for the externla journal debice when removing.
3939
3940E2fsprogs 1.23 (August 15, 2001)
3941================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04003942
3943Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04003944correctly handle a filesystem with EA's and check the EA blocks for
3945corruptions.
3946
Theodore Ts'od494bba2001-08-09 06:14:42 -04003947E2fsck's symlink sanity checking has been cleaned up. It now checks
3948the i_size value of fast symlinks, and checks for immutable flags
3949being set of symlinks, etc.
3950
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04003951E2fsck now offers to clear inodes which are special files that have a
3952non-zero i_blocks or i_size field. (The i_size field check was in the
3953previous version of the code, but due to a bug it didn't offer to
3954clear the inode unless i_size and i_size_high were both non-zero.)
3955
Theodore Ts'od494bba2001-08-09 06:14:42 -04003956E2image can now create "raw" image files, which only contain the
3957filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
3958debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04003959
3960Add support for the 64-bit block device patches.
3961
3962Fixed bugs in creating external journals with a 1k blocksize.
3963
Theodore Ts'od494bba2001-08-09 06:14:42 -04003964Add initial support for external journals (so long as the external
3965journal only supports a single filesystem) in e2fsck.
3966
3967Remove requirement for needing to run fsck on a filesystem after
3968removing a journal (either internal or external).
3969
Theodore Ts'obf16d102001-07-27 22:20:06 -04003970The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04003971
3972Speed up the check of an ext3 filesystems by avoiding a needless flush
3973of all of the superblock and block group descriptors.
3974
Theodore Ts'od494bba2001-08-09 06:14:42 -04003975Speed up creating an internal journal using tune2fs in the case where
3976the filesystem has a lot blocks already allocated.
3977
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04003978Tune2fs has been fixed to make sure that only error messages go to
3979stderr, and normal message go to stdout. (Addresses Debian bug #108555)
3980
Theodore Ts'od494bba2001-08-09 06:14:42 -04003981Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04003982now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04003983
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04003984Add support in fsck for the filesystem type "auto".
3985
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04003986Fsck -A will not try to interpret device names for filesystems which
3987have a pass number is 0. (Addresses Debian bug #106696).
3988
3989Fsck prints a warning message if now valid filesystems are passed to
3990it. (Addresses Debian Bug #107458.)
3991
Theodore Ts'o9249d982001-07-20 18:14:10 -04003992E2fsck now gives an explicit warning if there filesystem still has
3993errors at the end of the run. (Addresses Debian bug #104502)
3994
Theodore Ts'od494bba2001-08-09 06:14:42 -04003995E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04003996reflects an error. E2fsck will also not run the orphan list if the
3997filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04003998
3999E2fsck now prints the number of large files when given the -v option.
4000
4001Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04004002
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04004003Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04004004
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04004005
Theodore Ts'o19d6b542001-06-23 00:13:09 -04004006E2fsprogs 1.22 (June 22, 2001)
4007==============================
4008
4009Fixed a bug in e2fsck's handling of orphan inodes which are special
4010files (i.e., block/character device files, named FIFO's, etc.).
4011
4012Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
4013tune2fs to fail at adding a journal to a mounted filesystem.
4014
4015Fixed a few big-endian bugs in e2fsprogs
4016 * The directory block functions were accidentally reporting
4017 some directories as corrupted when they weren't.
4018 * If e2fsprogs is compiled --disable-swapfs, the C language
4019 equivalents weren't being included for big-endian platforms.
4020 (Fixes Debian bug #101686).
4021
4022Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
4023
4024Programmer's notes:
4025-------------------
4026
4027Use platform independent method of defining the BLKFLSBUF and FDFLUSH
4028ioctls, and allow them to be defined for non-i386 platforms.
4029
4030The uuid.h header file is now protected against multiple inclusions.
4031
4032E2fsprogs is now being developed using BitKeeper. Changed the test
4033scripts to deal with BK's stripping CR characgters from text files,
4034and changed the top-level Makefile.in to avoid including BitKeeper
4035files when generating the source tarball.
4036
4037
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004038E2fsprogs 1.21 (June 15, 2001)
4039==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00004040
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004041Added new configure flags which allow a subset e2fsprogs to be built;
4042this is most useful for boot floopies, since the resulting shared
4043libraries and programs are slimmed down by removing features that
4044aren't necessary for a boot floppy. The new flags that were added
4045are: --disable-swapfs, which removes support for byte swapping old
4046legacy PPC/68k filesystems, --disable-debugfs, which removes support
4047for debugfs from the libext2fs library, --disable-imager, which
4048removes support for the e2image program, and --disable-resizer, which
4049removes support for resize2fs.
4050
4051E2fsck now prints the number of mounts or days elapsed since the last
4052check when e2fsck is forced to check an otherwise clean filesystem.
4053
4054Tune2fs now prints an informative message about how often a filesystem
4055will be checked when adding a journal to the filesystem, to remind the
4056user that he/she may want to adjust those parameters using tune2fs
4057-c/-i.
4058
4059Worked around hurd brain-damage which causes e2fsck to sometimes
4060believe a filesystem is the root filesystem based on device numbers
4061(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
4062violation).
4063
4064Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
4065erroneous error with the -F option was specified.
4066
4067Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004068ext3 0.7a.
4069
Theodore Ts'o767de092001-06-02 01:20:18 +00004070Fixed two bugs in e2fsck's handling of dup block handling, dealing
4071with relatively uncommon edge cases: a directory with an indirect
4072block which is claimed by another file, and when the last inode in the
4073filesystem has blocks claimed by another file.
4074
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00004075E2fsck now checks to see if the i_size field of a fast symlink is too
4076big, and offers to clear the symlink if so.
4077
4078E2fsck now checks to see if i_size_high of special files is non-zero,
4079and offers to clear i_size_high.
4080
Theodore Ts'o767de092001-06-02 01:20:18 +00004081Fix e2fsck's handling of incompatible journal flags so that the user
4082has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00004083entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00004084
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004085Fixed a bug in fsck which could cause it to core dump if a mix of
4086standard and non-standard device names are used in /etc/fstab.
4087(Debian bug #100559)
4088
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004089Fixed a bug in debugfs which caused read errors when copying a file to
4090not be noticed.
4091
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004092The debugfs set_super_value command can now modify the s_lastcheck field.
4093
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004094Fixed a bug in lsattr and chattr which was accidentally introduced in
40951.20 to support > 2GB files; both lsattr and chattr wasn't reading
4096directories correctly because the change modified the layout of struct
4097dirent to be incompatible with the libe2p shared library.
4098
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004099Cleaned up the mke2fs manual page and included a discussion about why
4100it's good to periodically check the filesystem even when journaling is
4101enabled.
4102
Theodore Ts'o767de092001-06-02 01:20:18 +00004103Programmer's notes:
4104-------------------
4105
4106Fix general gcc -Wall complaints.
4107
4108The types needed by the ext2 header files are now provided by
4109lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
4110
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004111Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004112in ext2_types.h. Also, if linux/types.h has already been defined,
4113don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004114
Theodore Ts'o767de092001-06-02 01:20:18 +00004115Fixed make depend script so that it automatically corrects the
4116pathname cleanups performed by make -M, so I don't have to fix them up
4117by hand.
4118
4119Fixed the d_loaddump test case to be more robust, and not depend on
4120bash'isms.
4121
4122Removed debugfs's dependence on pread(), which was accidentally
4123intrudced in e2fsprogs 1.20
4124
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004125Fixed a performance bug in the libext2fs's icount routine; the size
4126estimate of the icount array was incorrectly being calculated.
4127
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004128Removed use of the badblocks compatibility functions in the e2fsprogs
4129programs.
4130
4131Added paranoia code which protects against strange cases where /etc
4132isn't on the root filesystem, or if /etc/mtab doesn't exist.
4133
4134The header file ext2_types.h is now installed.
4135
4136Autoconf is used to determine when we are on big-endian machines,
4137instead of doing run-time tests, to save a few bytes of code.
4138
4139The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
4140functions are no longer inline functions, which saves space and
4141doesn't really cost any real performance.
4142
4143The ext2fs library no longer depends on the e2p library. (What need
4144there was of it --- namely, fsetflags, was coded in-line).
4145
4146Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
4147when the user is stupid and tries compiling the package using "make
4148install" as root.
4149
4150Miscellaneous code cleanups:
4151 * Added missing files from Makefile.in's SRCS file, so that
4152 their dependencies would be properly calculated.
4153 * Removed redundant code
4154 * Fixed comments in code
4155 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00004158E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004159=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00004160
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004161Add support for replaying the ext3 journal purely in user mode,
4162including handling the orphaned inode list. Used code contributed by
4163Andreas Dilger, with bug fixes and the orphaned inode handling done
4164by Theodore Ts'o.
4165
4166The mke2fs and tune2fs programs can create or modify a filesystem to
4167include an ext3 journal. Tune2fs also can be used to remove an ext3
4168journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00004169
4170E2fsck will now check for the existence of a linked list of orphan
4171inodes in the superblock, and clear those inodes before starting the
4172rest of the filesystem check (but after the journal playback).
4173
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004174E2fsck now validates the file descriptor passed to the -C option,
4175which saves against the completion bar getting written to an
4176unexpected location, such as the disk being checked. (Debian
4177bug/wishlist #55220)
4178
4179E2fsck will now bump the filesystem revision number from zero to one
4180if any of the compatibility bits are set.
4181
4182Fixed a bug where a badly corrupted directory on a big endian system
4183could cause e2fsck to die with a bus error. The
4184ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
4185the ext2 library now does alignment sanity checks on the rec_len field
4186of the directory entry before using it.
4187
4188The ext2 library has been enhanced to make tune2fs safe to run on
4189mounted filesystems. (Users could usually get away with using tune2fs
4190on mounted filesystems before, but with the advent of ext3 and
4191journaling, it became important to make tune2fs was *really* safe for
4192use even when the filesystem being modified is mounted.) E2label is
4193now implemented by tune2fs using an argv[0] dispatch, so that e2label
4194is also now safe for use on mounted filesystems.
4195
4196Added a new program, e2image, which creates a backup of critical ext2
4197filesystem data structures. The generated image file can be examined
4198using dumpe2fs and debugfs. In the future, e2fsck will be able to use
4199the image file to help recover very badly damaged filesystems.
4200
4201Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
4202no longer cause e2fsck to bomb out. Also treat files > 2GB as being
4203large file when deciding whether or not the filesystem has large files.
4204
4205Fixed lsattr and chattr so that they work correctly on large files.
4206(Fixes Debian bug #72690.)
4207
4208Removed limitation in get_device_size() which imposed a one terrabyte
4209filesystem limitation. (Most 2.2 kernels still have a signed int
4210problem which cause 1 TB block device limitation. Fortunately, the
4211kernel patches to fix this are much easier than fixing the 2TB
4212limitation in the kernel. :-)
4213
4214A max_mount_count of zero is now treated as if no mount count were
4215set. (Previously, no mount count was indicated by using -1, and a
4216mount count of zero caused e2fsck to always be run.)
4217
Theodore Ts'o77648562001-05-14 13:04:44 +00004218Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004219
4220Mke2fs now adds some randomness in s_max_mount_count so that multiple
4221filesystems won't be all checked at the same time under normal
4222operations.
4223
Theodore Ts'o5570a652000-08-21 01:23:39 +00004224Fixed bug in the progress bar printing code which could cause e2fsck
4225to core dump on an illegal filesystem.
4226
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004227Fixed bug in fsck which could allow more than one instance of e2fsck
4228to be printing a progress bar. (Debian bug #65267)
4229
Theodore Ts'o5570a652000-08-21 01:23:39 +00004230Fsck using a UUID or a LABEL specifier will work even if devfs is
4231compiled into the kernel and not mounted. If the pathnames in
4232/proc/partitions are incorrect, fsck will search /dev for the correct
4233device (using the new ext2fs_find_block_device library function).
4234Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004235found when they are in use. Support has also been added to support
4236additional IDE disks and the DAC 960 device names. (Debian bug #94159)
4237
4238Fixed a bug in fsck which caused it not deal properly with 16
4239byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00004240
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00004241Fsck's -t option has been made a lot more flexible. The semantics for
4242what happens if a comma-separated list to fsck has been regularized,
4243and it is now possible to filter what filesystems will get checked
4244based what is in the filesystem's fstab entry's option field. (Debian
4245bug #89483.)
4246
Theodore Ts'o5570a652000-08-21 01:23:39 +00004247The dumpe2fs program can now print out the group description
4248information in hex, and also prints the location of the superblock and
4249block group descriptor for those block groups that have them.
4250
4251Mke2fs now clears the ext2 superblock before it starts creating a
4252filesystem, so that the superblock magic number is only written if the
4253filesystem creation process successfully completes.
4254
4255The debugfs program's stat command now pretty-prints the blocks used
4256by an inode so that it's more compact and informative.
4257
4258The debugfs stats command now uses the same libe2p code (which is used
4259by dumpe2fs) to print the superblock header information. This is more
4260complete, and it avoids a bit of code duplication.
4261
4262Added a new debugfs command, set_super_value (ssv) which allows the
4263user to set arbitrary superblock fields.
4264
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004265Debugfs was extended to support inode numbers in hex (by prefixing
4266them with 0x), and so that modify_inode can set the inode generation
4267number. Also, there is now a new function command called logdump
4268which will dump an ext3 journal.
4269
4270Fixed a bug in debugfs so that quitting out of the pager doesn't kill
4271debugfs.
4272
4273Debugfs's dump command now stops immediately upon reporting a disk
4274read error. (Fixed a bug in ext2fs_file_read library routine which
4275caused debugfs not to stop.) (Debian bug #79163)
4276
4277On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
4278checked before /etc/mtab is used, since /proc/mounts is more likely to
4279be accurate.
4280
4281Added portability fixes for Solaris and Linux/ia64.
4282
4283Various manual pages were clarified and cleaned up. (Fixed debian
4284bugs #63442, #67446, and #87216)
4285
Theodore Ts'o5570a652000-08-21 01:23:39 +00004286
4287Programmer's notes:
4288-------------------
4289
4290The e2fsck message printer now supports %Iu and %Ig, which will print
4291out the inode's user and group owners, respectively.
4292
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004293E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
4294that no longer dependent on the system having the correct version of
4295the kernel header files.
4296
Theodore Ts'o5570a652000-08-21 01:23:39 +00004297Added a new function to libext2, ext2fs_find_block_device(), which
4298searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
4299device given its device number.
4300
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004301Added a new function to libext2, ext2fs_sync_device, which centralizes
4302all of the places which might try to use the BLKFLSBUF or FDFLUSH
4303ioctls (and usually failing to define them since the system header
4304files don't usually do this for us, and we're trying to avoid usage of
4305kernel include files now).
4306
Theodore Ts'o5570a652000-08-21 01:23:39 +00004307Added new utility programs in tests/progs: random_exercise and
4308hold_inode. They aren't built by default; they're useful for
4309exercising ext3 filesystem code.
4310
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004311Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
4312the filesystem close functions to only update the superblock, and to
4313not touch the block group descriptors. Needed by tune2fs when
4314modifying a mounted filesystem.
4315
4316Got rid of struct ext2fs_sb and replaced it with the standard struct
4317ext2_super_block from include/linux/ext2_fs.h. Note: this may break
4318source (but not binary) compatibility of some users of the ext2
4319library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00004320replace of struct ext2fs_sb with struct ext2_super_block, and include
4321the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004322
4323The ino_t type has been renamed ext2_ino_t to protect applications
4324that attempt to compile -D_FILE_OFFSET_BITS=64, since this
4325inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
4326unexpected ABI change.
4327
4328The Makefiles have been reworked so that "make check" can be run from
4329the top-level Makefile.
4330
4331Fix general gcc -Wall complaints and removed dead code.
4332
4333Remove use of NOARGS, because we assume everyone does ANSI C these
4334days.
4335
4336Added build-rpm script from sct.
4337
4338New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
4339to support e2image.
4340
4341New function ext2fs_flush_icache which must be called if the
4342application program modifies the inode table blocks without going
4343through ext2fs_write_inode() interface.
4344
4345New ext2fs_check_mount_point() function, which will return the mount
4346point of a device if mounted.
4347
4348The io_channel abstraction now has an optional interface,
4349io_channel_write_range, which allows specific byte ranges to be
4350written.
4351
4352The unix_io IO channel now supports write-through caching, so that
4353journal creation is more efficient.
4354
4355Added x86 assembly language routines to support byte swapping, to
4356reduce executable size.
4357
4358Fixed bug in the utility program subst so that it's possible to
4359replace a substitution variable with a zero-length string.
4360
4361Fixed numbering e2fsck pass1 problem numbers; an extra zero had
4362slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00004363
Theodore Ts'ob777e262000-07-27 01:39:23 +00004364E2fsprogs 1.19 (July 13, 2000)
4365==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00004366
4367Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00004368be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00004369
4370Add experimental support needed for the ext2 compression patches.
4371This requires compiling e2fsprogs with the --enable-compression flag
4372to the configure script.
4373
4374Added ext3 journalling support. E2fsck will run the journal (if
4375necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
4376installed as a symlink to e2fsck. Fsck has been taught about ext3,
4377and treats it the same as ext2 in terms of the progress bar logic.
4378Dumpe2fs will display the superblock journaling information if the
4379filesystem has a journal. The ext2 library will now permit opening an
4380ext3 filesystem with the recovery flag set. This is necessary for
4381on-line dump's to work correctly, but there may be issues with this
4382working well since ext3 is much less agressive about syncing blocks to
4383the filesystem, since they're safe on the journal.
4384
4385Tune2fs and e2fsck have been changed to allow the mount_count check to
4386be disabled by setting max_mount_count to -1. (This was already
4387supported by the kernel.)
4388
4389Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
4390are used for ext3 as well.
4391
4392Added internationalization support for e2fsprogs; must be enabled
4393by passing --enable-nls to configure.
4394
4395Always use the provided ext2fs header files to insulate ourselves from
4396kernel version changes. Which include files are used by e2fsprogs
4397have also been cleaned up to improve portability.
4398
4399Limit the number of times that e2fsck updates the progress bar so that
4400people who are booting using a 9600 baud console don't get swampped by
4401too many updates.
4402
4403Improved the loop detection algorithm in e2sck's pass #3 so that it is
4404much, much faster for large filesystems with a large number of
4405directories.
4406
4407The memory footprint for e2fsck is now slightly smaller than before.
4408
4409E2fsck now checks if special devices have a non-zero size, and offers
4410to clear the size field if it finds such an inode.
4411
4412E2fsck now checks if special devices have the append-only flag set,
4413and offers to clear the inode.
4414
4415E2fsck now properly handles some "should never fail" cases during a
4416bitmap copy in pass5.
4417
4418E2fsck now properly prints control characters in filenames as ^A .. ^Z.
4419
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004420E2fsck now calculates the correct location of the backup superblock in
4421the case of filesystem blocksizes > 1k.
4422
4423Fixed a bug in e2fsck's calculation of the number of inodes_per_block
4424which normally didn't cause problems under most filesystem parameters,
4425but could cause a valid superblock to be rejected in extreme cases.
4426Other checks for validating superblock values were made more
4427stringent.
4428
Theodore Ts'oab146762000-07-07 04:37:35 +00004429Added non-destructive write testing to the badblocks program, courtesy
4430of David Beattie. The badblocks also now has an option to input the
4431current set of bad blocks, so that known bad blocks are skipped to
4432speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00004433feature which causes badblocks to run until it has completed some
4434number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00004435
4436Badblocks now checks to see if the device is mounted and refuses to do
4437the tests involving writing to the device if it is mounted. Also,
4438badblocks now allows the number of blocks to be checked to be
4439defaulted to the size of the partition.
4440
4441Fixed a bug in fsck which didn't allow non-root users to be able to
4442check filesystems if there were any LABEL= or UUID= entries in
4443/etc/fstab.
4444
4445The Hurd doesn't support the filetype filesystem feature. The mke2fs
4446program now makes sure that for the Hurd, the filestype feature is
4447turned off. E2fsck will check to see if the filetype feature is
4448turned on for Hurd filesystems, and offer to turn off the feature.
4449
4450Mke2fs now has a safety check to make sure the number of blocks do not
4451exceed 32 bits even on a 64 bit platform.
4452
4453Really fixed a bug in fsck to allow "fsck -As" to run interactive
4454fsck's. (For those people who like to do interactive fsck's in the
4455/etc/rc scripts!?!)
4456
4457Debugfs has a few new features: the rdump command, which will do a
4458recursive dump of a directory and all of its contents, and the lcd
4459command which does a local chdir (much like the ftp command of the
4460same name). In addition, the debugfs program and the open_filesystem
4461command now takes three new options: -b and -s, which allows the
4462blocksize and superblock location to be specified, and the -c option
4463which is used in catastrophic situations where the block group
4464descriptors are corrupt. If the -c option is specified, debugfs will
4465skip trying to read in the block and inode bitmaps.
4466
4467Debufs's lsdel command was fixed to handle bad blocks in the inode
4468table.
4469
4470A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
44714 digit years.
4472
4473General improvements in error messages
4474
4475 - Mke2fs prints a sane error message if the partition size is zero
4476 (usually because the partition table wasn't reread by the
4477 kernel due to the partition being busy), instead of "invalid
4478 argument passed to ext2 library while initializing superblock".
4479
4480 - Fsck now prints more self-explanatory message if an invalid UUID=
4481 or LABEL= specification is passed to it.
4482
4483UUID library changed to use the LGPL.
4484
4485Fixed a bug in the UUID library where very rapid calls to the
4486time-based UUID generator could cause duplicate UUID's to be returned.
4487This was not a problem for e2fsprogs, but it could be a problem for
4488other users of the library.
4489
4490Make the UUID library more robust in the face of missing or an
4491improper /dev/urandom or /dev/random files.
4492
4493Added some random portability fixes for Solaris.
4494
4495Some minor man page updates.
4496
4497Fixed a memory leak in the ss library.
4498
4499
4500Programmer's notes:
4501-------------------
4502
4503We now try to use lseek64 and open64 from the LFS if possible.
4504
4505The 3rd parameter in e2p's print_flags is now a flags word, instead of
4506a boolean option.
4507
4508The mark and unmark bitmap functions now return the previous state of
4509the bit that was being changed, which is useful for some speed
4510optimizations.
4511
4512The following functions have been added to enhance the badblocks list
4513handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
4514ext2fs_badblocks_equal.
4515
4516The ext2 header files now have the latest journalling fields to the
4517superblock.
4518
4519The ext2fs_mkdir function in libext2fs now properly backs out of error
4520conditions robustly.
4521
4522Cleaned up makefiles:
4523 - to cleanly compile with the -j flag.
4524 - so distclean removes all generated files.
4525 - so in case of an error while installing header files, the make aborts.
4526
4527Fix test_script so that it works correctly when compiling in the
4528source directory.
4529
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004530The random UUID generation routine has been made slightly better in
4531the case where /dev/random doesn't exist. (Use of randomly-based UUID
4532is still not recommended if /dev/random doesn't exist, however; it's
4533better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00004534
4535Clean up the build process so it's more friendly in case of missing
4536directories.
4537
4538The ext2fs header file can now be #include'd into C++ programs.
4539
4540The e2p.h header file is now installed.
4541
4542Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.

Theodore Ts'o24ded091999-11-10 15:56:16 +00004546E2fsprogs 1.18 (November 10, 1999)
4547==================================
4548
4549Fix a core dumping bug in e2fsck if an imagic inode is present or
4550(more rarely) if the filesystem is badly corrupted enough that e2fsck
4551has to restart pass 1 processing. E2fsck now closes the filesystem
4552before freeing a large number of its data structures, so in the case
4553of future memory faults, at least the fixed filesystem will be fully
4554written out.
4555
4556If a filesystem doesn't support imagic inodes, and e2fsck discovers an
4557imagic inode, it will offer to clear the imagic flag.
4558
4559E2fsck will now offer to clear the immutable flag on special files
4560(device/socket/fifos) when running it in non-preen mode.
4561
4562E2fsck will now set the filetype when creating /lost+found, and when
4563connected orphaned inodes to /lost+found.
4564
4565Debugfs's ncheck and icheck commands now handles the case where there
4566are bad blocks in the inode table without bombing out.
4567
4568The badblocks list processing code has been made more efficiently for
4569appending a large number of (ordered) badblocks to the badblocks list.
4570
4571Some minor man page updates.
4572
4573Fsck now allows interactive e2fsck's when using fsck -As (not a common
4574mode, but some people like to do this in boot scripts for silly reasons).
4575
4576Programmer's notes:
4577-------------------
4578
4579The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
4580with the problem code convention.
4581
4582The badblocks list regression test program has been updated to work
4583with previously made API name changes.
4584
4585The ext2fs_free() command now uses the new badblocks API to avoid
4586using the compatibility layer.
4587
4588Added new regression test cases; the run_e2fsck test script now
4589supports the ability for a test case to run a prepratory command
4590before running e2fsck.
4591
Theodore Ts'o28e11941999-10-26 18:17:20 +00004592E2fsprogs 1.17 (October 26, 1999)
4593=================================
4594
4595Fixed nasty typo in fsck which caused parallelized fsck's to go into an
4596infinite loop.
4597
4598Fixed a bug in fsck where it used strncmp to compare a binary UUID,
4599thus potentially causing problems if a binary UUID contained a NULL
4600character.
4601
4602E2fsck now uses stricter checks for directory entries in pass 2:
4603zero-length filenames are not allowed; neither are 8 byte long
4604directory entries.
4605
4606The debugfs "dirty" command now clears the filesystem valid bit.
4607(Previously this just set the dirty-as-in-needs-writing-out-to-disk
4608bit in the in-core superblock image. The new functionality is more
4609what the user expects, and is more useful.)
4610
4611Added a debugging hook to test parallel fsck; if the environment
4612variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
4613will be checked in parallel when they normally would not be.
4614
4615Programmer's notes:
4616-------------------
4617
4618Fixed some #ifdef's for compilation under the Hurd OS.
4619
4620Fixed minor W2K compatibility problems.
4621
4622Fixed some miscellaneous GCC warnings.
4623
4624
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00004625E2fsprogs 1.16 (October 22, 1999)
4626=================================
4627
4628Fixed a race condition bug in fsck; when printing a progress bar, if
4629checking multiple filesystems in parallel, it was possible for fsck to
4630send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
4631handler, which would cause it to terminate with a signal 10.
4632
4633E2fsck now properly handles filesystems that have the
4634INCOMPAT_FILETYPE feature turned on. It can be used to convert a
4635filesystem into using or not using FILETYPE feature.
4636
4637E2fsck now properly handles filesystems that have the IMAGIC feature
4638turned on (this is used on Linux AFS servers).
4639
4640The mke2fs program now creates filesystems that have the filetype and
4641sparse_superblock features enabled by default, unless it is run on a
4642pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
4643so there is now a new flag -O which allows the user to specify with
4644which features she would like to create the filesystem; "mke2fs -O
4645none" will create a filesystsem compatible with 2.0 kernels.
4646
4647The tune2fs program now has a -O option which allows the user to set
4648and reset "safe" filesystem features. Currently, the only ones which
4649allows to be modified are the filetype and sparse_superblock features.
4650Note setting or clearing either feature will require running e2fsck on
4651the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
4652requires that there is enough free space on the filesystem for the
4653extra superblocks which will be created by e2fsck.)
4654
4655Debugfs can now set and print filesystem features in the superblock
4656using the "features" command. Dumpe2fs will print out the complete
4657set of features when listing the superblock.
4658
4659Dumpe2fs has new options -f (force) and -h (header-only).
4660
4661Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
4662message to come up. This could happen when decrementing or
4663incrementing a link count could result in an overflow.
4664
4665Fixed a bug in e2fsck where the block count on the lost+found
4666directory would not be properly incremented when the directory was
4667expanded to the point where an indirect block needed to be allocated.
4668
4669E2fsck now makes some additional sanity checks on the superblock to
4670avoid crashing or giving a memory allocation error if some of the
4671values in the superblock are unresonable (but the superblock otherwise
4672looks valid).
4673
4674Fixed a bug in e2fsck where a very badly corrupted filesystem might
4675require two passes to completely fix the filesystem. This happened if
4676an inode claimed blocks that was part of the filesystem metadata
4677(typically, when garbage was written into an inode table or indirect
4678block, since this kind of filesystem corruption normally doesn't
4679happen otherwise).
4680
4681On the Alpha, glibc declares st_flags although it isn't actually used;
4682the configure script was improved to detect this case so that
4683e2fsprogs can avoid using the non-functional stat field.
4684
4685The manual pages were updated to use a more consistent formatting
4686style consistent with standard Unix man pages. Mke2fs's man page
4687added documentation for a few previously undocumented options.
4688
4689Fixed minor display bugs in tune2fs and mke2fs.
4690
4691Programmer's notes:
4692-------------------
4693
4694Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
4695
4696Added features to parse and print feature strings into the e2p library.
4697(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
4698
4699ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
4700whose directory entries contain proper filetype information if the
4701filesystem supports it.
4702
4703ext2fs_link() now uses the low 3 bits of its flags parameter to pass
4704the directory entry filetype information. This is used to set the
4705directory entry filetype information if the filesystem supports it.
4706
4707Fixed a bug in ext2fs_expand_dir() where the block count in a
4708directory's inode would not be properly incremented when the directory
4709was expanded to the point where an indirect block needed to be
4710allocated.
4711
4712
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00004713E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00004714==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00004715
4716Add configuration checks so that e2fsprogs will compile cleanly on
4717Linux 2.3 kernels that have renamed i_version to i_generation.
4718
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00004719E2fsck now prints a progress/completion bar (and not just a simple
4720spinner) if the -C0 option is requested or if it receives a SIGUSR1
4721signal. Fsck will automatically manage the (potentially muliple)
4722e2fsck processes to print completion bars if it is given a -C option,
4723with the right thing happening if multiple filesystems are being
4724checked in parallel.
4725
4726Mke2fs now has better automatic hueristics to determine the filesystem
4727parameters to be used for a particular filesystem. Added a new option
4728-T which allows the user to specify how the filesystem is to be used,
4729which helps mke2fs do a better job selecting the filesystem parameters.
4730
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00004731Mke2fs now creates revision 1 filesystems by default, and with the
4732sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00004733not understood by Linux 2.0 kernels, so they will only allow read-only
4734mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00004735
Theodore Ts'o6d53db31999-07-03 20:52:21 +00004736Fix bug where if /dev/null couldn't be opened (should never happen),
4737e2fsck would hang in a tight loop.
4738
4739Make e2fsck handle the case where /lost+found isn't a directory.
4740
4741E2fsck now uses mallinfo if it exists to get accurate statistics about
4742its memory usage.
4743
4744Fix bug in e2fsck where it wouldn't check to see if a disconnected
4745inode had any problems before connecting it to /lost+found.
4746
4747Add check to e2fsck so it makes sure that total number of inodes in
4748the filesystem is a sane number.
4749
4750Fix fencepost error when clearing an the end of the block bitmap which
4751caused the last block in the bitmap not to get cleared.
4752
4753Cleaned up a number of messages in e2fsck:
4754 * The message "Group's #'s copy of the group descriptor..."
4755 was fixed so that the correct number would be displayed.
4756 * Added missing space in the "disk write-protected" error messsage
4757 * Cleaned up the error message printed when a non-interactive
4758 e2fsck needs to abort a check because the filesystem
4759 appears to be mounted.
4760
4761Added a new command-line utility, uuidgen, which will create and print
4762a UUID.
4763
4764Make debugfs's icheck command more robust by checking to make sure an
4765inode has valid blocks before interarting over the inode's blocks.
4766
4767UUID generation now uses a random-based scheme whenever possible to
4768prevent potential privacy problems.
4769
4770Man pages for all of the UUID functions in the lirbary were added.
4771
4772Fixed bug in fsck so it won't coredump if a filesystem not in
4773/etc/fstab is given to it.
4774
4775Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
4776that most of the other mount utilities understands.
4777
4778Mke2fs will make a filesystem even if it appears mounted if the force
4779option is given.
4780
4781Dumpe2fs has new command-line options which allow a filesystem expert
4782to specify the superblock and blocksize when opening a filesystem.
4783This is mainly useful when examining the remains of a toasted
4784filesystem.
4785
4786The badblocks program has been updated to display correctly on disks
4787with large block numbers.
4788
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00004789The badblocks program no longer gives spurious errors when errors
4790occur on non-block boundaries, which is common if the blocksize is
4791larger than 1k.
4792
Theodore Ts'o6d53db31999-07-03 20:52:21 +00004793Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
4794MKE2FS_SYNC environment variable is set. This is to work around a VM
4795bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00004796to trigger it even using a 2.2 kernel, but hopefully it will not be
4797needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00004798
4799Fixed miscellaneous documentation and man pages.
4800
4801Programmer's notes:
4802-------------------
4803
4804Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
4805in e2fsck's pass1.c really should have been static.
4806
4807The return value of the uuid_compare() function was changed to make it
4808match with the convetions used by strcmp, memcmp, and Paul Leach's
4809UUID sample document.
4810
4811The "make depend" process has now been made more automated; it now
4812automatically word-wraps the dependencies, and only replaces source
4813Makefile.in if there has been a change in the dependencies. Also, a
4814top-level "make depend" now recurses through all the subdirectories
4815automatically.
4816
4817The Makefile in .../util has been changed so that subst is built using
4818the native C compiler during a cross-compilation, since the subst
4819program is only used during the build process. Also add an explicit
4820rule to build util/subst by cd'ing to the correct directory and
4821running Makefile.
4822
4823The man directories are defined in terms mandir, so that the configure
4824script can override the location of the manual pages.
4825
4826The config files have been updated to recognize new machine types for
4827both the i386 and alpha families.
4828
4829Fsck has been modified so that it will accurately create an
4830fsck_instance even when the noexecute flag is set. This allows for
4831accurate debugging of the fsck pass structure. Also, when the verbose
4832flag is given twice, fsck will print debugging information about when
4833fsck is waiting for jobs to finish.
4834
4835
Theodore Ts'o14790ed1999-01-12 23:32:52 +00004836E2fsprogs 1.14 (January 9, 1999)
4837================================
4838
4839Fix the fstab parsing code so that it can handle blank lines and
4840comment characters. Also, missing pass numbers need to be treated as
4841zero.
4842
4843Fixed a bug in e2fsck where under some circumstances (when e2fsck
4844needs to restart processing after fixing an egregious inconsistency)
4845it would try to access already freed memory.
4846
4847E2fsck now prints non-printable characters in directory entries and
4848pathnames using '^' and 'M-' notation.
4849
4850Fixed chattr so that it will ignore symbolic links when doing
4851recursive descent traversals. For both chattr and lsattr, no longer
4852print the version string unless the -V option is given.
4853
4854Allow the system administrator to directly specify the number of
4855inodes desired in the filesystem, for some special cases where this is
4856necessary.
4857
4858Fix portability problems so that e2fsprogs can be compiled under Linux
48591.2 systems and Solaris systems.
4860
4861Update the config.guess file with a more recent version that will
4862identify newer Linux platforms.
4863
4864Programmer's notes
4865------------------
4866
4867Ext2fs_read_inode and ext2fs_write_inode will now return an error if
4868an inode number of zero is passed to them.
4869
Theodore Ts'o556ad131998-12-19 08:10:58 +00004870E2fsprogs 1.13 (December 15, 1998)
4871==================================
4872
4873Fixed a bug in debugfs where an error messages weren't getting printed
4874when the ext2 library routines to read inodes returned errors in the
4875stat, cmri and rm commands.
4876
4877Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
4878provided, it won't create an inode table smaller than the minimum
4879number of inodes required for a proper ext2 filesystem.
4880
4881Fsck now parses the /etc/fstab file directly (instead of using
4882getmntent()), so that it can distinguish between a missing pass number
4883field and pass number field of zero. This caused problems for
4884diskless workstations where all of the filesystems in /etc/fstab have
4885an explicit pass number of zero, and fsck could not distinguish this
4886from a /etc/fstab file with missing pass numbers.
4887
4888E2fsck will create a /lost+found directory if there isn't one in the
4889filesystem, since it's safer to create the lost+found directory before
4890it's needed.
4891
4892Fixed e2fsck so that it would detect bogus immutable inodes which
4893happen to be sockets and FIFO files, and offer to clear them.
4894
4895If a filesystem has multiple reasons why it needs to be checked, and
4896one of the reasons is that it is uncleanly mounted, e2fsck will print
4897that as the reason why the filesystem is being checked.
4898
4899Cleaned up the output routines of mke2fs so that it doesn't overflow
4900an 80 column display when formating really big filesystems.
4901
4902Added a sanity check to e2fsck to make sure that file descriptors 0,
49031, 2 are open before opening the hard disk. This avoids a problem
4904where a broken program might exec e2fsck with those file descriptors
4905closed, which would cause disastrous results if the kernel returns a
4906file descriptor for the block device which is also used by FILE *
4907stdout.
4908
4909Fixed up the e2fsck progress reporting functions so that the values
4910reliably reach 100% at the completion of all of the e2fsck passes.
4911
4912Fixed minor documentation bugs in man pages and usage messages.
4913
4914Programmer's notes:
4915-------------------
4916
4917Fixed a number of lint warnings in the ext2fs library and potential
4918portability problems from other OS's header files that might define
4919CPP macros for names like "max" and "min".
4920
4921ext2fs_badblocks_list_add() has been made more efficient when it needs
4922to grow the bad blocks list.
4923
4924Fixed a bug in e2fsck which caused it to dereference a freed pointer
4925just before exiting.
4926
4927Fixed the substition process for generating the mk_cmds and compile_et
4928scripts so that they will work outside of the build tree.
4929
4930Add sanity check to e2fsck so that if an internal routine
4931(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
4932and causing a core dump. This should never happen, but...
4933
Theodore Ts'oa5696711998-07-09 05:38:07 +00004934E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00004935==================================
4936
4937E2fsprogs now works with glibc (at least with the version shipped wtih
4938RedHat 5.0). The ext2fs_llseek() function should now work even with
4939i386 ELF shared libraries and if llseek() is not present. We also
4940explicitly do a configure test to see if (a) llseek is in libc, and
4941(b) if llseek is declared in the system header files. (See standard
4942complaints about libc developers don't understand the concept of
4943compatibility with previous versions of libc.)
4944
Theodore Ts'oc9833a61998-07-05 19:37:53 +00004945The ext2fs library now writes out the block group number in each of
4946the superblock copies. This makes it easier to automatically
4947determine the starting block group of the filesystem when the block
4948group information is trashed.
4949
4950Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00004951which means that e2fsprogs will ignore the high 8 bits of the
4952directory entry's name_len field, so that it can be used for other
4953purposes.
4954
4955Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
4956E2fsprogs will now support filesystems with 64-bit sized files.
4957
4958Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
4959
Theodore Ts'o21d53851998-02-21 03:14:50 +00004960Added new program "e2label", contributed by Andries Brouwer. E2label
4961provides an easy-to-use interface to modify the filesystem label.
4962
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00004963Fixed bug so that lsattr -v works instead of producing a core dump.
4964
Theodore Ts'o21d53851998-02-21 03:14:50 +00004965Fixed a minor bug in mke2fs so that all groups with bad superblock
4966backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00004967
4968Mke2fs will check the size of the device, and if the user specifies a
4969filesystem size larger than the apparent size of the device it will
4970print a warning message and ask if the user wants to proceed.
4971
Theodore Ts'oc9833a61998-07-05 19:37:53 +00004972E2fsck has a new option -C, which sends completion information to the
4973specified file descriptor. For the most part, this is intended for
4974programs to use, although -C 0 will print a spinning character to the
4975stdout device, which may be useful for users who want to see something
4976happening while e2fsck goes about its business.
4977
Theodore Ts'o21d53851998-02-21 03:14:50 +00004978Fixed a bug in e2fsck which could cause a core dump when it needs to
4979expand the /lost+found directory, and sometimes the bitmaps haven't
4980been merged in. Also fixed a related bug where ext2fs_write_dir_block
4981was used to write out a non-directory block. (Which would be bad on a
4982non-Intel platform with byte swapping going on.)
4983
4984Fixed bug in e2fsck where it would print a "programming error" message
4985instead of correctly identifying where a bad block was in used when
4986the bad block was in a non-primary superblock or block group
4987descriptor. Also fixed a related bug when sparse superblocks are in
4988use and there is a bad block where a superblock or block group
4989descriptor would have been in a group that doesn't include a
4990superblock.
4991
4992Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
4993the block group descriptor table is corrupt, it was possible to try to
4994allocate a huge array, fail, and then abort e2fsck.
4995ext2fs_get_num_dirs() now sanity checks the block group descriptor,
4996and subsitutes reasonable values if the descriptors are obviously bogus.
4997
4998If e2fsck finds a device file which has the immutable flag set and the
4999i_blocks beyond the normal device number are non-zero, e2fsck will
5000offer to remove it, since it's probably caused by garbage in the inode
5001table.
5002
5003When opening a filesystem, e2fsck specially checks for the EROFS error
5004code, and prints a specific error message to the user which is more
5005user friendly.
5006
5007If the filesystem revision is too high, change the e2fsck to print
5008that this is either because e2fsck is out of date, or because the
5009superblock is corrupt.
5010
5011E2fsck now checks for directories that have duplicate '.' and '..'
5012entries, and fixes this corruption.
5013
5014E2fsck no longer forces a sync of the filesystem (with attendant sleep
5015calls) at all times. The ext2fs_flush() function now performs a sync
5016only if it needed to write data blocks to disk.
5017
5018Fixed a minor bug in e2fsck's pass1b's file cloning function, where
5019certain errors would not be properly reported.
5020
5021Updated and expanded a few points in the man pages which users
5022complained wheren't explicit enough.
5023
5024Added special case byte-swapping code if compiling on the PowerPC, to
5025accomodate the strange big-endian variant of the ext2 filesystem that
5026was previously used on the PowerPC port.
5027
5028
5029Programmer's notes:
5030-------------------
5031
5032Removed C++ keywords from the ext2fs libraries so that it could be
5033compiled with C++.
5034
5035E2fsck's internal organization has now been massively reorganized so
5036that pass*.c don't have any printf statements. Instead, all problems
5037are reported through the fix_problem() abstraction interface. E2fsck
5038has also been revamped so that it can be called as a library from a
5039application.
5040
5041Added new fileio primitives in libext2fs for reading and writing
5042files on an unmounted ext2 filesystem. This interface is now used by
5043debugfs.
5044
5045Added a new libext2fs function for mapping logical block numbers of
5046a file to a physical block number.
5047
5048Added a new libext2fs function, ext2fs_alloc_block(), which allocates
5049a block, zeros it, and updates the filesystem accounting records
5050appropriately.
5051
5052Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
5053sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
5054
5055The libext2fs functions now use a set of memory allocation wrapper
5056functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
5057instead of malloc, free, and resize. This makes it easier for us to
5058be ported to strange environments where malloc, et. al. aren't
5059necessarily available.
5060
5061Change the libext2fs fucntion to return ext2-specific error codes
5062(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
5063and depending on the existence of system error codes (such as EEXIST
5064and ENOENT).
5065
5066Renamed io.h to ext2_io.h to avoid collision with other OS's header
5067files.
5068
5069Add protection against ext2_io.h and ext2fs.h being included multiple
5070times.
5071
5072The types used for memory lengths, etc. have been made more portable.
5073In generla, the code has been made 16-bit safe. Added Mark
5074Habersack's contributed DOS disk i/o routines.
5075
5076Miscellaneous portability fixes, including not depending on char's
5077being signed.
5078
5079The io_channel structure has a new element, app_data, which is
5080initialized by the ext2fs routines to contain a copy of the filesystem
5081handle.
5082
5083ext2fs_check_directory()'s callback function may now return the error
5084EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
5085really do the checking, despite the presence of the callback function.
5086
5087
Theodore Ts'obc210071997-06-17 05:41:36 +00005088E2fsprosg 1.11 (June 17, 1997)
5089==============================
5090
5091Fixed e2fsck to detect (previously ignored) conflicts between the
5092superblock or block group descriptors and block bitmaps, inode
5093bitmaps, and inode tables.
5094
5095Fixed bug in e2fsck so that when the message printed out when a block
5096or inode bitmap conflicts with other data, it has the correct group
5097number.
5098
5099Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
5100to badblocks. This meant that not all of the filesystem was being
5101tested for bad blocks!
5102
5103Fixed an array boundary overrun case which cropped up in
5104ext2fs_badblocks_list_test when a user tried running "mke2fs -c
5105-b 4096".
5106
5107Adjusted the number of columns printed by mke2fs when displaying the
5108superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00005109really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00005110
5111Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
5112dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
5113fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
5114
5115Programmer's notes:
5116-------------------
5117
5118Fixed install rule in lib/ss so that ss_err.h is actually getting
5119installed.
5120
5121Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
5122bassed back to the caller.
5123
5124Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
5125setting the current inode number (which meant this function wasn't
5126working at all).
5127
5128Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
5129blocks in the bitmap when increasing the size of the bitmap.
5130
5131Changed the initial number of blocks allocated by ext2fs_init_dblist()
5132to be more realistic.
5133
5134Added a new function ext2fs_allocate_group_table, which sets up the
5135group descriptor information (and allocates inode and block bitmaps,
5136and inode tables for a particular group). The function was created by
5137factoring out code form ext2fs_allocate_tables().
5138
5139Added a new function ext2fs_move_blocks which takes a bitmap of the
5140blocks to be moved, and moves them to another location on the
5141boardboard.
5142
5143Make the unix_io channel's io_channel_flush implementation calls sync()
5144to to flush the kernel buffers to disk.
5145
5146Added a new function ext2fs_dblist_count returns the number of
5147directory blocks in dblist.
5148
5149
Theodore Ts'oae851481997-04-29 18:13:24 +00005150E2fsprogs 1.10 (April 24, 1997)
5151===============================
5152
5153Mke2fs once again defaults to creating revision #0 filesystems, since
5154people were complaining about breaking compatibility with 1.2 kernels.
5155Warning messages were added to the mke2fs and tune2fs man pages that
5156the sparse superblock option isn't supported by most kernels yet (1.2
5157and 2.0 both don't support parse superblocks.)
5158
5159Added new flag to mke2fs, -R <raid options>, which allows the user to
5160tell mke2fs about the RAID configuration of the filesystem. Currently
5161the only supported raid option is "stride" which specifies the width
5162of the RAID stripe.
5163
5164Fixed bug in e2fsck where pass1b would bomb out if there were any
5165blocks marked bad in the inode table.
5166
5167Fixed rare bug in mke2fs where if the user had a very unlucky number
5168of blocks in a filesystem (probability less than .002) the resulting
5169filesystem would be corrupt in the last block group.
5170
5171Fixed bug where if e2fsck tried to allocate a block to fix a
5172filesystem corruption problem and the filesystem had no free blocks,
5173ext2fs_new_block() would loop forever.
5174
5175The configure script now checks explicitly to see if "-static" works,
5176since that can't be assumed to be true --- RedHat doesn't install
5177libc-static by default.
5178
5179Fixed bug in libext2's block iterator functions where under some
5180cirmcustances, file with holes would cause the bcount parameter to the
5181callback function to be incorrect. This bug didn't affect any of
5182e2fsprogs programs, but it was discovered by Paul Mackerras, the
5183author of the PPC boot loader.
5184
5185Removed use of static variables to store the inode cache in libext2fs.
5186This caused problems if more than one filesystem was accessed via
5187libext2fs (static variables in libraries are generally a bad idea).
5188Again, this didn't affect e2fsprogs programs, but it was discovered by
5189Paul Mackerras.
5190
5191Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
5192will compile cleanly with 1.2.13 kernels (even with a.out shared
5193libraries!)
5194
5195Programmer's notes:
5196-------------------
5197
5198Added new functions to duplicate an ext2 filesystem handle, and its
5199associated substructure. New functions: ext2fs_dup_handle(),
5200ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
5201Other structures, such as the io_channel and the inode_cache, now have
5202a ref count so that they only get freed when they are no longer used
5203by any filesystem handle. (These functions were added as part of the
5204development effort for an ext2 resizer).
5205
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00005206E2fsprogs 1.09 (April 14, 1997)
5207===============================
5208
5209Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
5210accidentally introduced in the 1.08 release. The overhead calculation
5211was accidentally removed, which caused ext2fs_initialize() to not
5212notice when the filesystem size needed to be adjusted down because
5213there wasn't enough space in the last block group.
5214
5215Fixed bug in version parsing library routine; it was always parsing
5216the library version string, instead of using the passed-in string.
5217
5218Clarified chattr man page.
5219
Theodore Ts'o24757fa1997-04-29 17:39:27 +00005220E2fsprogs 1.08 (April 10, 1997)
5221===============================
5222
5223E2fsck 1.07 was very slow when checking very large filesystems with a
5224lot of files that had hard links (i.e., news spools). This was fixed
5225by seriously revamping the icount abstraction. Added a formal test
5226suite for the icount abstraction.
5227
5228Debugfs now has a "-l" option to the "ls" command, which lists the
5229inode number, permissions, owner, group, size, and name of the files
5230in the directory.
5231
5232Fix a bug in e2fsck where when a directory had its blocks moved to
5233another location during the pass 1b processing, the directory block
5234list wasn't updated, so pass 2 wouldn't check (and correct) the
5235correct directory block.
5236
5237E2fsck will now treat inodes which contain blocks which are claimed by
5238the filesystem metadata by treating them as multiply claimed blocks.
5239This way, the data in those blocks can be copied to a new block during
5240the pass 1b--1d processing.
5241
5242E2fsck will attempt to determine the correct superblock number and
5243display it in the diagnostic and warning messages if possible.
5244
5245Add support for a new (incompatible) feature, "sparse_super". This
5246feature reduces the number of blocks which contain copies of backup
5247superblocks and block group descriptors. (It is only an incompatible
5248feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
5249support a new -s option; e2fsck will recognize filesystems built with
5250this feature turned on.
5251
5252E2fsck now checks the library to make sure is the correct version,
5253using new library functions. (This helps to diagnose incorrectly
5254installed e2fsprogs distributions.)
5255
5256Dumpe2fs now prints more information; its now prints the the
5257filesystem revision number, the filesystem sparse_super feature (if
5258present), the block ranges for each block group, and the offset from
5259the beginning of the block group.
5260
5261Mke2fs now distributes the inode and block bitmap blok so that the
5262won't be concentrated in one or two disks in RAID/striping setups.
5263Also, if the user chooses a 2k or 4k block group, mke2fs will try to
5264choose the largest blocks per group that be chosen. (For 2k blocks,
5265you can have up to 16384 blocks/group; for 4k blocks, you can have up
5266to 32768 blocks/group.) Previously mke2fs would not allow
5267specification of more than 8192 blocks per group, even if you were
5268using a 2k or 4k block group.
5269
5270Programmer's notes:
5271-------------------
5272
5273Added a new function ext2fs_create_icount2() which takes a "hint"
5274argument. This hint argument presets the icount array with the list
5275of inodes which actually need to be in the icount array. This really
5276helps to speed up e2fsck.
5277
5278Added a new function ext2fs_icount_validate() which checks the rep
5279invariant for the icount structure. This is used mostly for testing.
5280
5281The error mesasage given when a bad inode number is passed to
5282test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
5283EXT2FS_UNMARK_ERROR).
5284
5285Added a new function ext2fs_set_dir_block which sets the block of a
5286dblist entry, given the directory inode and blockcnt.
5287
5288Added a new function ext2fs_get_library_version() which returns the
5289current library version, and ext2fs_parse_version_string() which
5290returns a version number based on a e2fsprogs version string.
5291
5292The icount functions will return EINVAL if the passed in inode number
5293is out of bounds.
5294
Theodore Ts'o21c84b71997-04-29 16:15:03 +00005295E2fsprogs 1.07 (March 9, 1997)
5296==============================
5297
5298E2fsck is now uses much less memory when checking really large
5299filesystems (or rather, filesystems with a large number of inodes).
5300Previously a filesystem with 1 million inodes required 4 megabytes of
5301memory to store inode count statistics; that storage requirement has
5302now been reduced to roughly half a megabyte.
5303
5304E2fsck can now properly deal with bad blocks appearing inside the
5305inode table. Instead of trying to relocate the inode table (which
5306often failed because there wasn't enough space), the inodes in the bad
5307block are marked as in use.
5308
5309E2fsck will automatically try to use the backup superblocks if the
5310primary superblocks have a bad magic number or have missing meta-data
5311blocks (or meta-data blocks which are out of range).
5312
5313E2fsck's pass 3 has been made more efficient; most noticeable on
5314filesystems with a very large number of directories.
5315
5316Completely revamped e2fsck's system of printing problem reports. It
5317is now table driven, to make them more easily customizeable and
5318extendable. Error messages which can be printed out during preen mode
5319are now one line long.
5320
5321Fixed e2fsck's filesystem swapping code so that it won't try to swap
5322fast symbolic links or deleted files.
5323
5324Fixed e2fsck core dumping when fixing a filesystem which has no
5325directories (not even a root directory).
5326
5327Added a check to e2fsck to make sure that the length of every
5328directory entry is a multiple of 4 (since the kernel complains if it
5329isn't).
5330
5331Added a check to e2fsck to make sure that a directory entry isn't a
5332link to the root directory, since that isn't allowed.
5333
5334Added a check to e2fsk to now make sure the '.' and '..' directory
5335entries are null terminated, since the 2.0 kernel requires it.
5336
5337Added check to write_bitmaps() to make sure the superblock doesn't get
5338trashed if the inode or block bitmap is marked as being block zero.
5339
5340Added checking of the new feature set fields in the superblock, to
5341avoid dealing with new filesystem features that this package wasn't
5342set up to handle.
5343
5344Fixed a fencepost error in ext2fs_new_block() which would occasionally
5345try to allocate a block beyond the end of a filesystem.
5346
5347When the UUID library picks a random IEEE 802 address (because it
5348can't find one from a network card), it sets the multicast bit, to
5349avoid conflicting with a legitimate IEEE 802 address.
5350
5351Mke2fs now sets the root directory's owner to be the real uid of the
5352user running mke2fs. If the real uid is non-zero, it also sets
5353the group ownership of the root directory to be the real group-id of
5354the user running mke2fs.
5355
5356Mke2fs now has more intelligent error checking when it is given a
5357non-existent device.
5358
5359When badblocks is given the -vv option, it now updates the block that
5360it is currently testing on every block.
5361
5362Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
5363currently correctly if PATH wasn't already set.
5364
5365Shared libraries now built with dependencies. This allows the shared
5366library files to be used with dlopen(); it also makes the transition
5367to libc 6 easier, since ld.so can tell which libc a particular shared
5368library expects to use.
5369
5370Programmer's notes:
5371-------------------
5372
5373Added new abstraction (defined in dblist.c) for maintaining a list of
5374blocks which belongs to directories. This is used in e2fsck and other
5375programs which need to iterate over all directories.
5376
5377Added new functions which test to see if a contiguous range of blocks
5378(or inodes) are available. (ext2fs_*_bitmap_range).
5379
5380Added new function (ext2_inode_has_valid_blocks) which returns true if
5381an inode has valid blocks. (moved from e2fsck code).
5382
5383Added new function (ext2fs_allocate_tables) which allocates the
5384meta-data blocks as part of initializing a filesystem. (moved from
5385mke2fs code).
5386
5387Added a new I/O manager for testing purposes. It will either allow a
5388program to intercept I/O requests, or print debugging messages to
5389trace the activity of a program using the I/O manager.
5390
5391The badblocks_list functions now store the bad blocks in a sorted
5392order, and use a binary search to speed up badblocks_list_test.
5393
5394The inode scan function ext2fs_get_next_inode() may now return a soft
5395error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
5396those cases where part of an inode table is missing or there is a bad
5397block in the inode table.
5398
5399Added a new function (ext2fs_block_iterate2) which adds new arguments to
5400the callback function to return a pointer (block and offset) to the
5401reference of the block.
5402
5403Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
5404application to jump to a particular block group while doing an inode
5405scan.
5406
5407The badblocks list functions were renamed from badblocks_* to
5408ext2fs_badblocks_*. Backwards compatibility functions are available
5409for now, but programs should be modified to use the new interface.
5410
5411Some of the library functions were reorganized into separate files to
5412reduce the size of some programs which statically link against the
5413ext2 library.
5414
5415Put in some miscellaneous fixes for the Alpha platform.
5416
Theodore Ts'o5c576471997-04-29 15:29:49 +00005417
5418E2fsprogs 1.06 (October 7, 1996)
5419================================
5420
5421Fixed serious bug in e2fsck: if the block descriptors are bad, don't
5422smash the backup copies in ext2fs_close(). (The problem was that when
5423e2fsck -p discovered the problem, while it was closing the filesystem
5424and exiting, it was also blowing away the backup superblocks on the
5425disk, which was less than friendly.) We now make it the case that we
5426only write out the backup superblock and the back block descriptors if
5427the filesystem is completely free from problems.
5428
5429Fixed a bug in block_interate in the lib/ext2fs library which caused
5430e2fsck to fail on GNU Hurd-created filesystems.
5431
5432Add support for Linux/FT's bootloader, which actually uses
5433EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
5434to clear the inode.
5435
5436Add support for the "A" (no atime update) attribute. (Note: this
5437attribute is not yet in production kernels.)
5438
5439The test suite is not automatically run when doing a "make all" from
5440the top level directory. Users should manually run "make check" if
5441they wish to run the test suite.
5442
5443Upon a preenhalt(), make the printed message more explicit that
5444running e2fsck "MANAULLY" means without the -p or -a options.
5445
5446In e2fsck, if a disconnected inode is zero-length, offer to clear it
5447instead of offering to connect it to lost+found.
5448
5449In e2fsck, if a filesystem was just unmounted uncleanly, and needs
5450e2fsck to be run over it, change e2fsck to explicitly display this
5451fact.
5452
5453For dumpe2fs and e2fsck, cause the -V option to print out which
5454version of the ext2fs library is actually getting used. (This will
5455help detect mismatches of using a 1.06 utility with a 1.05 library,
5456etc.)
5457
5458Programmers' notes:
5459-------------------
5460
5461EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
5462the naming convention.
5463
5464In ext2fs_initialize(), make sure the description for the inode bitmap
5465is correctly initialize.
5466
5467Fixed minor type typo in ext2fs_allocate_generic_bitmap();

Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00005469E2fsprogs 1.05 (September 7, 1996)
5470==================================
5471
5472Add support for new fields in the ext2 superblock --- volume name,
5473volume UUID, and last mounted field. Dumpe2fs displays these fields,
5474tune2fs and mke2fs allows you to set them. E2fsck will automatically
5475generate a UUID for those volumes that don't have them.
5476
5477Put in support for e2fsck to recognize HURD specific ext2 features ---
5478most notably, the translator block. The e2fsprogs tools will now use
5479the creator_os field in the superblock to correctly handle different
5480OS-specific variants of the ext2 filesystem.
5481
5482E2fsck now fixes inodes which have a the deletion time set, but which
5483have a non-zero i_link_count field by offering to clear the deletion
5484time. Previously e2fsck assumed that the inode was deleted (per 0.3c
5485ext2 kernel behavior) and offered to unlink the file.
5486
5487If e2fsck sets the clean bit, but nothing else, set the exit code
5488FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
5489set the filesystem valid bit when it was previously cleared. :-) This
5490was needed to make the HURD fsck driver happy.
5491
5492If the user refuses to attach an unattached inode, e2fsck will no
5493longer set the inode's link count. Otherwise, the inode would end up
5494getting marked as unused, which might cause loss of data later.
5495
5496Make the message issued by e2fsck when the superblock is corrupt less
5497confusing for users. It now mentions that another reason for the
5498"corrupt superblock" message might be that the partition might not be
5499an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
5500
5501Make the libext2 library more robuest so that e2fsck won't coredump on
5502an illegal superblock where the blocksize is zero. (f_crashdisk is
5503the test case).
5504
5505By default, create filesystems where the default checkinterval is 6
5506months (180 days). Linux servers can be robust enough that 20 reboots
5507can be a long, long time.
5508
5509Added configure flag --enable-old-bitops, which forces the bitops to
5510use the old (native) bitmask operations. By default on the sparc
5511platform, the standard ext2 bit ordering is now used.
5512
5513Added a new feature to e2fsck to byte-swap filesystems; this can be
5514used to convert old m68k filesystems to use the standard byte-order
5515storage for the superblock, inodes, and directory blocks. This
5516function is invoked by using the '-s' option to e2fsck.
5517
5518Debugfs's "dump" command has been enhanced so that it writes out the
5519exact size of the file so that the nulls at the end of the file are
5520eliminated. The command also accept a new "-p" option which will
5521attempt preserve to preserve the ownernship, permissions, and
5522file modification/access times.
5523
5524Debugfs has two new options, -f and -R. The -R option allows the user
5525to execute a single debugfs command from the command line. The -f
5526option allows the user to specify a "command file" containing debugfs
5527commands which will get executed.
5528
5529Dumpe2fs now pretty prints the check interval, instead of just
5530printing the check interval as a number of seconds.
5531
5532Fix bugs in debugfs: the params command when no filesystem is opened
5533no longer causes a core dump. It is now possible to unlink a file
5534when a pathame containing a '/' is specified.
5535
5536Tune2fs has a new -C option which sets the number of times the
5537filesystem has been mounted.
5538
5539Fix the chattr '-v' option so that it actually works. Chattr was
5540being buggy about the -v option parsing.
5541
5542Programmers' notes:
5543-------------------
5544
5545The directory lib/uuid contains a set of library routines to generate
5546DCE compatible UUIDs.
5547
5548Extended ext2fs_namei() to handle symbolic links. Added new function
5549ext2fs_nami_follow() which will follow last symbolic link in the case
5550where the pathname points to a sym link.
5551
5552The ext2fs_block_iterate function will now return the HURD translator
5553block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
5554iterator to return data blocks only. The ext2fs.h file now defines
5555constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
5556BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
5557count field of the iterator callback function.
5558
5559The test script driver now takes an optional second argument, which is
5560the test case to be run. This allows you to run a test case without
5561needing to run the entire test suite.
5562
5563On Linux ELF systems, install the .so files in the correct places
5564(/usr/lib). The .so files must be stored in the same directory as the
5565.a files.
5566
5567Fixed miscellaneous HURD compilation issues with header file being
5568included in the right order.
5569
5570Fixed debugfs so that it resets optind to zero, not one, since setting
5571optind to zero is more correct.
5572

Theodore Ts'oa4d09611997-04-29 14:28:00 +00005574E2fsprogs 1.04 (May 16, 1996)
5575=============================
5576
5577First "official" (1.03 was a limited release only) to support building
5578e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
5579kernels).
5580
5581This package includes a RPM specs file, that it can be built using the
5582RedHat Package Manager.
5583
5584E2fsck now prints a hint that if there are lots of incorrectly located
5585inode bitmaps, block bitmaps, and inode table blocks, the user might
5586want to try using e2fsck -b 8193 first, to see if that fares any
5587better.
5588
5589For ext2 filesystem written with the hurd, debugfs will now print out
5590the translator field when printing an inode structure.
5591
5592Lots of miscellaneous linking/installation cleanups:
5593
5594 Libraries are now linked using a relative pathname, instead of
5595 relying on -L working correct. It doesn't, in many cases, including
5596 current versions of GNU ld. This guarantees that the build tree is
5597 linking with the right libraries, instead of the ones installed in
5598 /usr/lib.
5599
5600 Header files, man pages, and the et/ss shell scripts are now
5601 generated using a custom substitution script, instead of relying on
5602 the configure script. This prevents needless recompilation of
5603 files; in addition, the custom substitution script is much faster.
5604
5605 e2fsck may now be linked dynamically, by using the
5606 --enable-dynamic-e2fsck flag to configure. This is not recommended,
5607 since it increases e2fsck's dependence on other files, but some
5608 people need to save disk space, and other critical programs on their
5609 systems were being linked dynamically anyway.
5610
5611 Programs such as fsck which didn't need to be linked against
5612 libext2fs (or mke2fs which didn't need to be linked against libe2p)
5613 only link against libraries they actually need. Otherwise, those
5614 programs would require the presense of libraries that otherwise
5615 could be removed from a rescuse diskette.
5616
5617 The ss include files are now installed correctly so they can
5618 actually be used by another package.
5619
5620 If the profiling libraries are built, they are now installed on a
5621 "make install-libs".

Theodore Ts'o7f88b041997-04-26 14:48:50 +00005624E2fsprogs 1.03 (March 27, 1996)
5625===============================
5626
5627Change the m68k bit numbering for bitmasks to match the bit numbering
5628used by all other ext2 implementations. (This change was requested by
5629the m68k kernel development team.)
5630
5631Support (in-development) filesystem format revision which supports
5632(among other things) dynamically sized inodes.
5633
5634Fixed a bug in the ext2 library so that an intelligent error is
5635returned if mke2fs is run with a ridiculously small number of blocks
5636for a partition.
5637
5638Fixed a bug in the ext2 library which required that the device be
5639openable in read/write mode in order to determine its size. This
5640caused e2fsck -n to require read/write access when it was not
5641previously necessary.
5642
5643Fixed a bug in e2fsck which casued it to occasionally fail the test
5644suite depending on which version of the floating point library it was
5645using.
5646
5647Fixed a bug in e2fsck so that it now halts with a fatal error when
5648certain superblock consistency checks fail. Previously it continued
5649running e2fsck, with some potential confusing/damaging consequences.
5650
5651Added new flag to fsck which allows the root to be checked in parallel
5652with other filesytems. This is not the safest thing in the world to
5653do, but some system administrators really wanted it.
5654
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00005655Fixed -Wall flames in lib/ss.
5656
Theodore Ts'o74becf31997-04-26 14:37:06 +00005657
5658E2fsprogs 1.02 (January 16, 1996)
5659=================================
5660
5661Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
5662
5663Change e2fsck to print statistics of how many non-contiguous files are
5664on the system. Note that a file which is larger than 8k blocks, it is
5665guaranteed to be non-contiguous.
5666
5667In mke2fs, print a warning message if a user tries to format a whole
5668disk (/dev/hda versus /dev/hda1). If a user really wants to format a
5669whole disk, the -F (force) option forces mke2fs to format a whole disk
5670as a filesytem.
5671
5672Fix a bug in fsck where in some cases it might start checking
5673partitions in the next pass before it finishes checking partitions in
5674the current pass. This still won't cause two partitions on the same
5675disk will be checked, so it's rarely a problem in real life.
5676
5677Patch lsattr so that it won't hang when checking a named pipe.
5678
5679Minor compilation fixes:
5680 * Fix the order of libraries that were linked in debugfs.
5681 * Allow the sources to be compiled with -ansi turned on.
