Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001E2fsprogs 1.40-WIP (October 2, 2006)
2====================================
3
4Fixed overflow and signed/unsigned problems caused by the number of
5blocks or inodes exceeding 2**31 or being close to 2**32-1;.
6
7Fix resize2fs so that it gives user-intelligible error messages if the
8filesystem or the kernel does not support on-line resizing.
9(Addresses Debian Bug: #380548)
10
11Require mke2fs -F -F for really dangerous operations, since -F is
12needed for less dangerous operations such as creating filesystems
13images in regular files, or creating filesystems on whole block
14devices. These relatively innocuous usages should NOT be confused
15with running mke2fs on an apparently-mounted or in-use filesystem.
16
17Allow the default inode size to be specified into the mke2fs.conf
18file.
19
20Make the smallest default journal size is big enough so that on-line
21resizing should always work.
22
23Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
24#1531372)
25
26Fix debugfs coredump when lsdel is run without an open filesystem
27(Addresses Debian Bug: #378335)
28
29Fix debugfs display bug us that bytes that have the high bit set are
30displayed as "ec" instead of "ffffffec".
31
32Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
33
34Device mapper scanning wasn't working in the blkid library because the
35pathnames had an extra "/dev" when they were being probed.
36
37Add GFS/GFS2 support to the blkid library.
38
39Fix blkid support of empty FAT filesystem labels.
40
41Avoid recursing forever (or for a long time) when the blkid library
42searches for a device and there are symlinks to directories in /dev.
43
44Avoid unaligned halfword access in blkid when accessing FAT
45superblocks, as this will cause Sparc/Solaris systems to throw a
46SIGBUS error.
47
48The latest devmapper libraries requires pthreads, add -lpthreads to
49the static link libraries for e2fsck.static if devmapper is enabled.
50(Addresses Debian bug: #388718)
51
52Improve the (non-installed, for experts only) findsuper program by
53printing the uuid and label from the superblocks, as well as the
54starting and ending offsets of the filesystem given the information in
55the superblock. Omit by default printing superblocks that are likely
56found in located in an ext3 journal unless an explicit -j option is
57given.
58
59Updated French and Dutch translations and added Vietnamese translation.
60
61Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
62determining a partition's size, since binary searching to determine
63the device doesn't work on FreeBSD.
64
65Fixed spelling mistakes, typos, and otherwise clarified man pages.
66(Addresses Debian Bug: #369761, #373004)
67
68Fixed various Debian packaging issues --- see debian/changelog for
69details. (Addresses Debian Bugs #389554, #390664)
70
71
72Programmer's notes:
73-------------------
74
75Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
76(Addresses Sourceforge Bug: #1565561)
77
78Remove unused variables and other lint/gcc -Wall cleanups
79
80Add check to ext2fs_get_device_size() so it will return EFBIG for for
81filesystems contained in regular files where the filesystem image size
82is returned by stat64().
83
84Added the 64-bit byte swapping function ext2fs_swab64().
85
86Added two new helper functions to prevent 2**31/2**32-1 overflow
87problems: ext2fs_div_ceil() and e2p_percent().
88
89Create new ext2fs library inline functions ext2fs_group_first_block()
90and ext2fs_group_last_block() in order to calculate the starting and
91ending blocks in a block group.
92
93Create the generated files read-only to remind developers not to edit them.
94
95Added an "make rpm" target to top-level Makefile
96
97Added various FreeBSD portability fixes.
98
99Exclude mercurial files from the RPM build tree to speed up copy/build.
100
101Use root_sysconfdir to define the locations of mke2fs.conf and
102e2fsck.conf instead of using a hard-coded /etc pathname.
103
104Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
105
106Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
107
108If diff -u is supported, use it to report test failures.
109
110Updates/improvements to RPM spec file

Theodore Ts'o6c094752006-05-29 11:47:25 -0400113E2fsprogs 1.39 (May 29, 2006)
114=============================
Theodore Ts'o34a26112006-03-29 20:40:23 -0500115
Theodore Ts'o34a26112006-03-29 20:40:23 -0500116Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
117between 2**31 and 2**32 blocks.
118
Theodore Ts'o34a26112006-03-29 20:40:23 -0500119Change mke2fs to use /etc/mke2fs.conf as a configuration file to
120configure the filesystem features, blocksize, and inode_ratio for
121different filesystem types.
122
Theodore Ts'o6c094752006-05-29 11:47:25 -0400123Mke2fs will now create filesystems hash trees and on-line resizing
124enabled by default, based on the new /etc/mke2fs.conf file.
125
Theodore Ts'o34a26112006-03-29 20:40:23 -0500126The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
127filesystem device node in exclusive mode to prevent accidents by
128system administrators. In the case of resize2fs and mke2fs, it will
129only use exclusive mode if the filesystem is not mounted.
130
131Fixed a bug in mke2fs which caused it to to fail when creating the
132resize inode for large filesystems. (Addresses Debian Bug #346580)
133
Theodore Ts'obae55642006-05-14 17:31:48 -0400134When allocating space for the RAID filesystems with the stride
135parameter, mke2fs will now place each portion of the group's inode
136table right up after the superblock (if present) in order to minimize
137fragmentation of the freespace.
138
139Speed up mke2fs and e2fsck by writing inode and block bitmaps more
140efficiently by writing the inode and block bitmaps in one pass, thus
141reducing the number of disk seeks required.
142
Theodore Ts'o34a26112006-03-29 20:40:23 -0500143Add support for on-line resizing to resize2fs.
144
145Fix blkid library so that logic to determine whether or not a device's
146cached information in /etc/blkid.tab needs to be verified or not
147doesn't get confused by a system clock which is insane (for example,
148if the battery is dead on a Macintosh running PPC Linux. (Addresses
149Red Hat Bug: #182188)
150
151The blkid library will now store the UUID of the external journal used
152by ext3 filesystems, so that in the future, the userspace mount binary
153can use this to find the location of the external journal and pass
154this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -0500155
156E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -0500157control how various options should be handled. See the e2fsck.conf
158man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -0500159
Theodore Ts'o34a26112006-03-29 20:40:23 -0500160E2fsck now prints an explanatory message when delaying a filesystem
161check when the system is running on battery. (Addresses Debian Bug:
162#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400163
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500164E2fsck will detect if the superblock's last mount field or last write
165field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -0500166#327580) These problems will be fixed automatically in preen mode
167since Debian's boot sequence bogusly doesn't set the time correctly
168until potentially very late in the bootup process, and this can cause
169false positives which will cause users' systems to fail to boot.
170(Addresses Debian Bugs #343662 and #343645)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400171
Theodore Ts'o34a26112006-03-29 20:40:23 -0500172E2fsck now checks to see if the superblock hint for the location of
173the external journal is incorrect, and if so, offer to update it.
174(Addresses Debian Bug: #355644)
175
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400176Fix e2fsck from segfaulting on disconnected inodes that contain one or
177more extended attributes. (Addresses Debian Bug: #316736, #318463)
178
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500179E2fsck will stop and print a warning if the user tries running a
180read/write badblocks test on a read-only mounted root filesystem.
181
Theodore Ts'obae55642006-05-14 17:31:48 -0400182Fix a memory leak in e2fsck's error paths. (Thanks to Michael
183C. Thompson for pointing these out; they were originally found using
184Coverity.)
185
Theodore Ts'of3227852005-12-31 16:45:29 -0500186When resizing a file containing a filesystem, resize2fs will expand or
187truncate a file as necessary. (Addresses Debian Bug: #271607)
188
Theodore Ts'obae55642006-05-14 17:31:48 -0400189Resize2fs will now automatically determine the RAID stride parameter that
190had been used to create the filesystem, and use that for newly created
191block groups. The RAID stride parameter may also be manually specified
192on the command line using the new -S option to resize2fs.
193
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500194Fix mke2fs so that it correctly creates external journals on
195big-endian machines (such as a S/390).
196
Theodore Ts'obae55642006-05-14 17:31:48 -0400197Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
198fail to print out the journal or hash seed UUID. (Thanks to Guillaume
199Chambraud for pointing this out.)
200
201Dumpe2fs will now print the size of the journal (if present).
202
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500203Fix debugfs's set_inode_field command so it can properly set the frag,
204fsize, uid_high, gid_high, and author fields in the inode instead of
205silently failing, and so that setting the i_size actually sets i_size
206correctly.
207
208Add a new debugfs command, set_current_time, which sets fs->now so
209that regression test suites can repeatedly modify the filesystem's
210last_write fields.
211
Theodore Ts'o34a26112006-03-29 20:40:23 -0500212Fix a bug in debugfs's icheck which would incorrectly report the owner
213of an extended attribute block.
214
Theodore Ts'obae55642006-05-14 17:31:48 -0400215Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
216print a usage message when an illegal option character is given.
217
Theodore Ts'o6c094752006-05-29 11:47:25 -0400218Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
219so it won't core dump. (Addresses SourceForge bug #1424311)
220
Theodore Ts'obae55642006-05-14 17:31:48 -0400221Fix mklost+found so that it creates a full-sized directory on
222filesystems with larger block sizes.
223
224Fix a file descriptor leak in blkid library.
225
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500226Fix a display bug in "badblocks -sv" so that the done message properly
227clears the block number at the end of the test. (Addresses Debian Bug
228#322231)
229
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400230Allow fractional percentages to the -m option in mke2fs and tune2fs
231(Addresses Debian Bug: #80205)
232
233Use fstat/fstat64 in getsize.c if the the target is a regular file,
234instead of attempting to do a binary search. Fix some fd leaks in
235error cases.
236
Theodore Ts'o34a26112006-03-29 20:40:23 -0500237Add support for device mapper library to the blkid library to ensure
238that the "best" (i.e., leaf) device is probed by the blkid library.
239
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500240Fix the blkid library so that it notices when an ext2 filesystem is
241upgraded to ext3.
242
243Improve the blkid's library VFAT/FAT detection; it now understands
244labels stored in the root directory, and is more paranoid about
245checking the FAT superblock values.
246
Theodore Ts'o34a26112006-03-29 20:40:23 -0500247Fixed a fd leak in the uuid library which was causing problems for the
248LVM tools. (Addresses Debian Bug: #345832)
249
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500250Add support for the reiser4 and software suspend partitions to the
251blkid library. Also add support for extract the label from iso9660
252filesystems.
253
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400254Fix a compile_et bug which miscount the number of error messages if
255continuations are used in the .et file.
256
257Add extra sanity checks to protect users from unusual cirucmstances
258where /etc/mtab may not be sane, by checking to see if the device is
259reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
260#319002)
261
Theodore Ts'o34a26112006-03-29 20:40:23 -0500262Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
263Bug: #343149, #341911, #300871, #316604, #316782, #330789)
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500264
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400265Fix use-after-free bug in e2fsck when finishing up the use of the
266e2fsck context structure.
267
Theodore Ts'o34a26112006-03-29 20:40:23 -0500268Fixed spelling mistakes, typos, and otherwise clarified man pages and
269documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

Theodore Ts'o4c02c412005-12-09 19:20:01 -0500272
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400273Fixed various Debian packaging issues --- see debian/changelog for
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500274details. (Addresses Debian Bugs #317862, #320389, #290429, #310950,

Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400278
279Programmer's notes:
280-------------------
281
Theodore Ts'o7e2ec012006-04-22 04:29:16 -0400282Update config.guess and config.sub to latest version (2006-02-23) from
283FSF.
284
285Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
286Bugs: #360661, #360317)
287
Theodore Ts'o34a26112006-03-29 20:40:23 -0500288Fixed the Makefile so that they work correctly on newer versions of
289GNU make (i.e., 3.81).
290
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400291Add valgrind support to the regression test suites, and eliminate
292false positives from valgrind.
293
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500294Add a regression test suite for the blkid library.
295
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400296Fix a fencepost error in resize2fs caught by valgrind.
297
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500298Fix compiler warnings about missing memcpy prototypes.
299
300We no longer have the sparc assembly code in the header file any more,
301so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
302break compiles on the sparc architectures when using gcc.
303
304In the libext2fs library, add the new field fs->now which if non-zero
305is used instead of the system time when setting various filesystem
306fields (last modified time, last write time, etc.)
307
308Fix gcc 4.01 complaints by adding a missing #include <string.h> to
309ext2fs.h which is needed since the inline functions use memcpy().
310(Addresses Sourceforge Bug #1251062)
311
312Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
313the build system when building files in the util directory which are
314needed during the build process. This avoids potential problems when
315cross-compiling and some of the options specified in CFLAGS or LDFLAGS
316are not recognized as valid by the host compiler. (Addresses
317Sourceforge Bug #1261547)
318
319Clean up the blkid library by making the superblock and generic i/o
320functions to be more generic. Clean up interface to the probe
321function, and fix memory leak. Finallly, remove an unneeded reference
322to probe.h in the lib/blkid/resolve.c
323
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500324Add an ext2fs_read_bb_FILE regression test to confirm proper detection
325of invalid block #'s.
326
Theodore Ts'o34a26112006-03-29 20:40:23 -0500327The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
328indicate that the the function read/writes the memory location.
329
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500330Fix various gcc -Wall complaints.
331
332Add a dependency to make sure that the subdirectories are created
333before creating all of the object files, in order to address parallel
334build problem in the library Makefiles. (Addresses Sourceforge Bug:
335#1261553)
336
337Add $(LDFLAGS) to the command line argument when generating an ELF or
338Solaris shared library, to allow cross-compile and other builds that
339might need to specify -L paths to needed libraries. (Addresses
340Sourceforge Bug #1261549)
341
Theodore Ts'obae55642006-05-14 17:31:48 -0400342Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
343intended for testing purposes. It allows an ext2/ext3 developer to
344create very large filesystems using sparse files where most of the
345block groups are not initialized and so do not require much disk
346space. Eventually it could be used as a way of speeding up mke2fs and
347e2fsck for large filesystem, but that would be best done by adding an
348RO_COMPAT extension to the filesystem to allow the inode table to be
349lazily initialized on a per-block basis, instead of being entirely
350initialized or entirely unused on a per-blockgroup basis.
351
Theodore Ts'o6c094752006-05-29 11:47:25 -0400352Fix backwards compatibility so e2fsprogs will better compile on Linux
3532.0.35 systems.
354
355Make test scripts more robust against locale-related environment variables
356
357Fix type warning problem with sizeof() in ext2fs_open2().
358
359Fix type warning problem with time_t in debugfs.

Theodore Ts'ofea95ff2005-07-01 17:31:55 -0500362E2fsprogs 1.38 (June 30, 2005)
Theodore Ts'o1f965c82005-06-30 20:06:45 -0400363==============================
364
365Fix blkid's test programs (built with "make check") compile correctly
366even without "configure --enable-blkid-debug".
367
368Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
369type aliasing rules on newer gcc compilers. (Addresses Red Hat
370Bugzilla ##161183.)
371
372Fix com_err library to make it more compatible with recent changes
373made to the com_err library in MIT Kerberos V5 version 1.4.
374(Addresses Sourcefroge Bug #1150146)
375
376General cleanup of messages printed by e2fsprogs programs for grammar,
377consistency, and to make life easier for translators. Fixed a few
378strings containing English that had not been marked as needing
379translations. Removed strings that do not need to be translated, to
380make life easier for translators.
381
382Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
383test to see if a device appears to be in use instead of just relying
384on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
385
386Fix portability problem in the filefrag program affecting platforms
387where the size of an integer is smaller than the size of a long.
388(Addresses Debian Bug #309655)
389
390Mke2fs will now use a larger journal by default for filesystems
391greater than 4GB. (128 MB instead of 32MB).
392
393Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
394unless forced. This is to avoid signed vs. unsigned kernel bugs in
395block numbers that still need to be fixed.
396
397The blkid program has a new option which will more efficiently search
398for device when it is known (or expected) that only one matching
399device will be found in the system, such as when doing a lookup by
400UUID.
401
402Debian's e2fsprogs-specific initrd fragment will avoid including
403unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
404and LD_LIBRARY_PATH, and filtering out libraries found in
405/etc/ld.so.preload. (Addresses Debian Bug: #304003)
406
407Fixed a potential portability issue in the blkid programs for
408architectures where the char type is unsigned. (Addresses Sourceforge
409Bug: #1180585)
410
411Fix a bug in filefrag so that it doesn't falsely count an extra
412discontinuity when the first block found is an indirect block.
413(Addresses Debian Bug #307607).
414
415Fix blkid's recognition of cramfs filesystems, and enhance it to be
416able to handle cramfs labels.
417
418Fix debugfs's stat command to not core dump when a filesystem is not
419open.
420
421Fix e2fsck's handling of error conditions caused by the resize inode
422claiming blocks that are also used by other inodes, a filesystem
423corruption which was commonly caused by a bug in Fedora Core 3's
424resize2fs program.
425
426Fixed bug in filefrag which caused it to fail on non-ext2/3
427filesystems. (Addresses Debian Bug: #303509)
428
429If the superblock last mount time indicates that the system clock may
430not be accurate, then e2fsck will omit checking inodes' deletion time
431field for indications of a potential corrupted orphaned inode list.
432(Previously e2fsck only ommited these LOW_DTIME checks when the
433superblock's last write time looked insane.)
434
435Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
436(Addresses Debian bug #302200)
437
438Make the blkid library more paranoid about being run from setgid
439programs, and to use __secure_getenv() from libc if it is available.
440
441Fixed spelling mistakes, typos, and otherwise clarified man pages.
442(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
443and Sourceforge Bug: #1189803)
444
445Updated and fixed translations.
446
447Fixed various Debian packaging issues --- see debian/changelog for
448details.
449
450Programmer's notes:
451-------------------
452
453Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
454changed to take an unsigned int for the bit number. Negative bit
455numbers were never allowed (and didn't make any sense), so this should
456be a safe change. This is needed to allow safe use of block numbers
457greater than or equal to 2**31.
458
459The compile_et program will avoid recreating generated foo_err.c and
460foo_err.h files if no changes are necessary. The compile_et program
461will also atomically replace these files to avoid a potential parallel
462build race problem on SMP systems. (Addresses Sourceforge Bug:
463#1157933)
464
465Added a new function to the blkid library, blkid_probe_all_new(),
466which only probes newly added disk devices, and change
467blkid_find_dev_with_tag() to use this function so that when a
468requested tag is not found, devices that were previously not checked
469are searched before searching all devices in the system.
470
471Added new functions to the blkid library, blkid_dev_set_search() and
472blkid_dev_has_tag().
473
474E2fsck's problem strings can now use @m and @n as abbrevations for
475"multiply-claimed" and "invalid", respectively.
476
477The e2fsprog.pot file now has an explanation of how the @-expansion
478and %-expansion works, and strings in e2fsck/problem.c which contain @
479characters now have comments in e2fsprogs.pot with the @-expansion to
480make life easier for translators.
481
482Fixed missing return values in the ext2fs library which could cause it
483to return random garbage in certain error conditions.
484
485Allow the current time to be overriden via the E2FSCK_TIME environment
486variable for use in regression tests.
487
488The test scrpit driver program now exits with a non-zero status if
489there any of its test that it ran failed.
490
491Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
492Bug: #1157933)
493
494Fixed "make check" so that it compiles correctly even when e2fsprogs'
495header files have not be installed in the system include directories.
496(Addresses Sourceforge Bug: #1180572)
497
498Fixed gcc -Wall nits.

Theodore Ts'ofd4b28e2005-03-21 22:37:03 -0500501E2fsprogs 1.37 (March 21, 2005)
502===============================
503
504Add support for checking the validity of Extended Attributes stored in
505inodes to e2fsck.
506
507Add support for dumping the contents of large inodes to debugfs,
508including the extended attributes stored in inodes.
509
510Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
511when we create a new inode we make sure that the extra information in
512the inode (any extra fields in a large inode and any ea-in-inode
513information) is initialized correctly. This can take place when
514mke2fs creates the root and lost+found directory, when e2fsck creates
515a new root inode or a new lost+found directory, and when the user uses
516the debugfs write, mknod, or mkdir commands. Otherwise, the newly
517create inode could inherit garbage (or old EA information) from a
518previously deleted inode.
519
520Fixed a bug in e2fsck so it would notice if a file with an extended
521attribute block was exactly 2**32 blocks, such that i_blocks wrapped
522to zero.
523
524Added support to filefrag to detect files which are using the new
525experimental file extents format, and use the non-ext2 algorithm in
526that case. Fixed a bug to avoid reporting a false discontinuity if
527there is one or more unallocated blocks at the beginning of a file.
528
529Duplicated a check for noticing whether or not the number of blocks
530(given a certain blocksize) is greater than 2**32 when the
531BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
532allows mke2fs to automatically use a larger blocksize when creating a
533filesystem on a very large device when run on systems that do not
534support BLKGETSIZE64.
535
536Fix the I18N build which was broken in e2fsprogs 1.36 because the
537build system had been switched to treat the .gmo files as shipped
538files (for backwards compatibility with systems that have older GNU
539I18N tools installed), but the gen_tarball.in script was still
540removing the .gmo files from the official source distribution.
541
542Fixed various Debian packaging issues --- see debian/changelog for
543details. (Addresses Debian Bugs ##296769, #299341)
544
545Programmer's notes:
546-------------------
547
548Added new functions to the e2p library which convert between a string
549and os_type: e2p_os2string() and e2p_string2os(), and used them to
550make the generated binaries more compact.
551
552Fixed a compile-time error on Darwin systems.
553
554Cleaned up the lib/ext2fs Makefile slightly.
555
556
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500557E2fsprogs 1.36 (February 4, 2005)
558=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500559
560All of the patches that were applied to Fedore Core 3's
561e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
562lot of bug fixes first. Users of Fedora Core 3 are strongly
563encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
564
565Add support for filesystem with the online resizing via resize inode
566feature. Fixed numerous bugs from the Fedora patches. The Fedora
567patches also didn't bother to do any consistency checking on the
568resize inode, or add any tests to the regression test suite. The "-R
569resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
570being listed in mke2fs's usage message. All of these shortcomings
571have been corrected.
572
573E2fsck can also also fix filesystems trashed by Fedora's resize2fs
574program. In order to do this, the user must run the commands:
575
Theodore Ts'od0a3b462005-05-05 22:57:44 -0400576 debugfs -w /dev/hdXXX -R "features ^resize_inode"
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500577 e2fsck -f /dev/hdXXX
578
579Optionally, the ext2prepare command can be used to re-enable online
580resizing after the filesystem has been fixed.
581
582The fsck program will now accept an optional filedescriptor argument
583to the -C option. (The Fedora version of this patch would sometimes
584cause fsck to ignore a parameter on fsck's command line in some rare
585cases, sigh.)
586
Theodore Ts'odc256972005-01-26 13:20:12 -0500587Make sure e2fsprogs doesn't write garbage into the reserved portion of
588large inodes.
589
590Make sure resize2fs releases the blocks belonging to the old inode
591table blocks when moving the inode table. (Addresses Debian Bug:
592#290894)
593
594Skip the r_resize_inode test if resize2fs is not compiled (due to
595configure --disable-resizer)
596
597E2fsck now checks the summary filesystem accounting information, and
598if any of the information is obviously wrong, it will force a full
599filesystem check. (Addresses Debian Bug #291571)
600
601Fix e2fsck to not complain when the resize_inode feature is enabled,
602s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
603the resize inode.
604
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500605Fix e2fsck to note delete symlinks that contain an extended attribute
606after the ext_attr feature flag has been cleared. (Addresses Red Hat
607Bugzilla #146284).
608
Theodore Ts'odc256972005-01-26 13:20:12 -0500609Add new utility program, copy_sparse.c, which is very useful
610for dealing with large sparse files (such as e2image files).
611
612Add support for jnl_blocks[] for debugfs's set_super_value.
613
614Fix filefrag so that it works correctly with sparse files.
615
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500616Filefrag -v will print first and last blocks.
617
Theodore Ts'odc256972005-01-26 13:20:12 -0500618Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
619and dumpe2fs.
620
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500621Add mke2fs support so that it can support filesystems larger than 4TB
622automatically, by retrying with a 4k blocksize if the device size is
623too big to be expressed using a 1k blocksize. (Addresses Sourceforge
624bug #1106631)
625
Theodore Ts'odc256972005-01-26 13:20:12 -0500626Change blkid to test for NTFS first because Windows sometimes doesn't
627clear enough of the parition to confuse the probing routines into
628thinking the old filesystem type is still valid. (Addresses Debian
629Bug #291990)
630
Theodore Ts'o66fa0de2005-01-11 14:39:55 -0500631Add support for swap partition label and uuid's in the blkid library.
632
Theodore Ts'odc256972005-01-26 13:20:12 -0500633Add support to the blkid library to recognize Oracle ASM volumes.
634
635Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500636not just the first one, and work more consistently when the blkid
637cache file is not available or set to /dev/null. (Addresses Debian
638Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -0500639
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500640Badblocks will now correctly display block numbers greater than
641999,999,999 in its progress display.
642
643The tune2fs program will not allow the user from setting a ridiculous
644number of reserved blocks which would cause e2fsck to assume the
645superblock was corrupt. E2fsck's standards for what is a ridiculous
646number of reserved block has also been relaxed to 50% of the blocks in
647the filesystem.
648
649The blkid library will return vfat in preference to msdos, and ext3 in
650preference to ext2 (if the journalling flag is set) so that mount will
651do the right thing. (Addresses Debian bug #287455)
652
653Mke2fs will now use the -E option for extended options; the old -R
654(raid options) option is still accepted for backwards compatibility.
655Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
656
657Mke2fs will now accept a size in megabytes, gigabytes, and other units
658(via "32m" or "4g" on the command line) if the user finds this more
659convenient than specifying a block count.
660
661Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
662cache conherency problem.
663
664Debugfs now supports a new command, set_inode_field, which allows a
665user to manually set a specific inode field more conveniently, as well
666as set entries in the indirect block map.
667
668Debugfs's set_super_value command has been enhanced so that the user
669can set most superblock fields, including the date/time fields and
670some of the more newsly added superblock fields.
671
672E2fsprogs programs now accept an offset to be passed to the file
673specifiers, via the syntax: "/tmp/test.img?offset=1024".
674
675E2fsprogs programs will now accept blocksizes up to 65536; kernel
676support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500677other architectures with page sizes greater than 4k. There are 2.6
678kernel patches out there which enable this, but they are of this
679writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500680
Theodore Ts'o4ee558f2005-01-19 02:20:04 -0500681The e2image command now takes the -s option which will scramble
682directory entries for raw image files.
683
684Fix a file descriptor leak in the filefrag program.
685
686Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
687present.
688
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500689Fix bug in debugfs where kill_file would lead to errors when deleting
690devices and symlinks. (Sourceforge Bugs #954741 and #957244)
691
692Fix bug in the blkid library when detecting the ocfs1 filesystem
693
694Remove obsolete EVMS 1.x and a.out DLL support.
695
696E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -0400697
698Fixed two potential ordering constraint problems in e2fsck which might
699cause the filesystem to be corrupted if e2fsck is interrupted during a
700(extremely narrow) race window. Thanks to Junfeng Yang from the
701Stanford Metacompilation group for pointing this out.
702
703Fixed bug in e2fsck where it would not accurately detect whether or
704not the system is running on adaptor if the ACPI device representing
705the AC adapter didn't correspond to the what was used on IBM
706Thinkpads.
707
708Change e2fsck to accept directories greater than 32MB.
709
710Fix e2fsck so that a checkinterval of zero disables a time-based check
711of the filesystem.
712
713Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
714to the PAGER environment variable. (Addresses Debian Bug #239547)
715
716Tune2fs will not mark rewrite the superblock if the feature bitmasks
717are not modified.
718
719The debugfs program will set the filetype information when creating a
720link.
721
722Add debugfs -d option to use a separate source of data blocks when
723reading from an e2image file.
724
725Add e2image -I option which allows the e2image metadata to be
726installed into a filesystem.
727
728Fixed bug in the badblocks program which caused "done" to always
729appear in english even when a translation was available. (Addresses
730Debian Bug #252836)
731
732The blkid program has a new option -o which controls the output format
733of the blkid program; this is makes blkid more convenient to use in
734shell scripts.
735
736Fix a minor bug in uuid library, which was not using the full 14 bits
737of clock sequence when generating UUID's.
738
739Fix a Y8.8888K problem in the uuid library.
740
741Logsave now creates a new session id for itself to avoid getting
742killed by init whan transitioning between init levels.
743
744Change the licensing of the UUID library to be the 3-clause BSD-style
745license; this allows Apple to use the uuid library in Darwin.
746
747Add ocfs and ocfs2 probe support into the blkid library.
748
749Fix a memory and file descriptor leak in the blkid library.
750
751The blkid library will revalidate the device if the system time is
752earlier than last verification time of the device, since that
753indicates that the system time is probably nottrustworthy.
754
755The blkid library will override the default location of the blkid.tab
756file by the BLKID_FILE environment variable, if it is available.
757
758Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
759
760Add various portability fixes for lame new versions of glibc, Darwin
761and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500762Bugs #239934, #264630, #269044, #255589, #289133)
763
764Add support for Windows 9x/NT under Cygwin.
Theodore Ts'o48301122004-09-19 08:23:41 -0400765
766Updated and clarified various man pages. (Addresses Debian Bugs #236383,
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500767 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
Theodore Ts'o48301122004-09-19 08:23:41 -0400768
769Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
770
771Update the rpm spec files so that it works better with Fedora core 2
772and RH9.
773
774Fixed various Debian packaging issues (see debian/changelog). In
775particular, fixed the Debian initrd scripts. (#241183, #248050,
776#253595, #247775)
777
778
779Programmer's notes:
780-------------------
781
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500782Fixed various gcc -Wall warnings.
Theodore Ts'o48301122004-09-19 08:23:41 -0400783
784The uuid library now has new functions uuid_unparse_upper() and
785uuid_unparse_lower() which forces the case of the hex digits to be
786upper case, or lower case.
787
788The build process has been speeded up by enhancing the subst program
789to update the modtime on the generated files even when the generated
790file hasn't changed.
791
792The uuid library now uses C99 stdint.h types instead of custom types.
793
794Updated config.guess and config.sub with newer versions from the FSF.
795
796Removed out of date .cvsignore files from the source distribution.
797
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500798The ext2fs_unlink() function will return an error if both the name and
799inode number are unspecified, to avoid doing something surprising
800(such as unconditionally deleting the first directory entry).
801Directory entries are now deleted by coalescing them with the previous
802directory entry if possible, to avoid directory fragmentation. This
803is not an issue with the e2fsprogs suite, but may be a problem for
804some of the users of libext2fs, such as e2tools.
805
806Add support for version numbers of the form "1.36-rc1".
807
Theodore Ts'o48301122004-09-19 08:23:41 -0400808Fix build of mke2fs.static.
809
Theodore Ts'odc256972005-01-26 13:20:12 -0500810Add basic ext2fs library support for large (EA in inode) inodes.
811
Theodore Ts'o48301122004-09-19 08:23:41 -0400812The test_io mechanism can now abort after n reads or writes to a
813particular block. The block is specified by TEST_IO_BLOCK environment
814variable, and the read/write count by the TEST_IO_READ_ABORT and
815TEST_IO_WRITE_ABORT environment variables. The block data is now only
816dumped if the 0x10 bit is set in TEST_IO_FLAGS.
817
818UUID_DEFINE() in the uuid library now creates a static variable, with
819__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
820be used in header files.
821
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500822Add support for the install-strip and install-shlibs-strip targets, as
823suggested by the GNU coding guielines. "make install" no longer
824strips the binaries which are installed.
825
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500826Remove support for the --enable-old-bitops configure option which was
827only for very old sparc systems.
828
829Remove support for --enable-clear-htree; this was only needed during
830the early development of the htree patch.
831
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500832Use Linux-kernel-style makefile output so it is easier to see compiler
833warnings.
834
835Update gettext files to version 0.14.1.
836
837Update to use autoconf 2.5x.
838
839Improved support for compiling e2fsprogs under dietlibc.
840
Theodore Ts'o4ee558f2005-01-19 02:20:04 -0500841Make e2fsprogs portable to Solaris and FreeBSD systems.
842
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500843Add blkid_verify(), blkid_get_library_version(), and
844blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -0500845
846Add pkg-config files for e2fsprogs's libraries.
847
848Fix "make uninstall" to so that it removes everything that is installed.
849
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500850Add a configure --enable-maintainer-mode option which enables the
851makefile rules to rebuild the configure script from configure.in, and
852to reubuild the .gmo files in po directory.
853
854Drop the sparc assembly bitwise operations; it's less efficient
855than the GCC 3.4 compile code and triggers compiler warnings on
856sparc64. Thanks to Matthias Andree for his analysis and suggestions.

Theodore Ts'ob70b1162004-02-28 10:52:35 -0500860E2fsprogs 1.35 (February 28, 2004)
861==================================
862
Theodore Ts'o48301122004-09-19 08:23:41 -0400863E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500864preserves the existing badblocks list.
865
Theodore Ts'o48301122004-09-19 08:23:41 -0400866Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500867
868E2fsprogs will now deal correctly with symlinks that contain
869extended attribute information, which can be created using SE Linux.
870(Addresses Debian Bug #232328)
871
872Remove a double longjump into an invalid stack frame bug in e2fsck.
873(This was during an abort sequence, which normally worked on Linux and
874caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500875
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500876Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
877(the NLS library will replace "" with the .po header information).
878
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500879Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
880dump due to a division by zero error. (Addresses Debian bug #207082)
881
Theodore Ts'o151a7162003-12-26 14:04:33 -0500882Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
883when reconnecting a directory requires creating a lost+found
884directory. (Addresses Debian bug #219640).
885
886Fixed a bug where e2fsck would bomb out if a journal needed to be
887replayed when using an alternate superblock.
888
Theodore Ts'o48301122004-09-19 08:23:41 -0400889E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500890if the laptop is running on battery. The next time fsck runs while
891the system is on the AC mains, or after the grace period is exceeded,
892the filesystem will be checked. (Addresses Debian bug #205177)
893
894E2fsck will inform the user when there are 5 or fewer mounts before a
895filesystem check will be forced. (Addresses Debian bug #157194)
896
897Fix e2fsck's handling of corrupted indirect blocks in the bad block.
898We now correctly handle the case where there is an overlap between a
899block group descriptor or a superblock and a bad block indirect block.
900In the case where the indirect block is corrupted, we now suggest
901"e2fsck -c".
902
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500903Fix byte swap bugs in e2fsck that caused the journal backup location
904in the superblock and symlinks created by SE Linux to be cleared
905by e2fsck on big-endian machines. (Addresses Debian bug #228723)
906
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500907E2fsck -c now replaces the current list of bad blocks with the ones
908found by badblocks.
909
910Fix bugs in e2fsck and tune2fs which could cause a core dump if a
911non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
912
913Fix a potential bug in e2fsck which could cause it to core dump when
914trying to print the location of the backup superblock.
915
916Protect against a potential core dump in e2fsck when printing a
917message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400918
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400919Add support for backing up the journal inode location in the
920superblock. E2fsck will automatically save the journal information in
921the superblock if it is not there already, and will use it if the
922journal inode appears to be corrupted. ext2fs_add_journal_inode()
923will also save the backup information, so that new filesystems created
924by mke2fs and filesystems that have journals added via tune2fs will
925also have journal location written to the superblock as well.
926Debugfs's logdump command has been enhanced so that it can use the
927journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500928
929E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400930
931Shrink the size of the e2fsck executable by moving some initialized
932variables to the BSS segment.
933
934E2fsck will avoid printing the ^A and ^B characters which bracket the
935progress bar when stdout and stdin are a tty device instead of a pipe
936to another program. (Addresses Debian bug #204137)
937
Theodore Ts'o151a7162003-12-26 14:04:33 -0500938Debugfs's mkdir command will automatically expand the directory if
939necessary. (Addresses Debian Bug: #217892)
940
941Fixed a bug in debugfs so that copying a file from /dev/null uses the
942correct mode bits. (Addresses Debian Bug: #217456)
943
944If the environment variables DEBUFS_PAGER and PAGER are not set,
945debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -0500946/usr/bin/pager, and then falling back to 'more' and 'less'.

948
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500949Debugfs will now support 2.6 device numbers where the major or minor
950number may be larger than 255. (Addresses Sourceforge bug #865289)
951
Theodore Ts'o48301122004-09-19 08:23:41 -0400952Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
953
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500954Chattr now stops processing options when it sees '--'. (Addresses
955Debian bug #225188)
Theodore Ts'o151a7162003-12-26 14:04:33 -0500956
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400957Fix regression tests so they work correctly when e2fsprogs is compiled
958with configure --disable-htree.
959
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500960Fix bug in uuid library when there is no network card and the library
961is generating a time-based uuid. The random MAC address was not
962correctly generated to be a multicast address.
963
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400964Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -0400965around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400966
967Fix bug in badblocks when using O_DIRECT; we need to make sure that
968we're reading from an offset which is page aligned. For read-only and
969read-write tests, we try to recover after an error so that we can
970continue reading on page-aligned boundaries. (Addresses Debian Bug
971#203713)
972
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500973Badblocks now checks 64 blocks at a time instead of 16. (Addresses
974Debian bug #232240)
975
Theodore Ts'o151a7162003-12-26 14:04:33 -0500976Updated and clarified various man pages. (Addresses Debian Bug

983Programmer's notes:
984-------------------
985
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500986Fixed a build problem so that e2fsprogs would compile with the
987--enable-profile option to configure selected. (Addresses Sourceforge
988bug #811408)
989
990Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
991Bugzilla Bug #112448)
992
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500993Centralize code which calculates the location of the superblock
994and block group descriptors so that it is in a single library routine.
995
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400996Added two new functions, ext2fs_file_open2() and
997ext2fs_inode_io_intern2() which take a pointer to an inode structure.
998
999Fix compile_et to output the correct prototype for
1000initialize_xxx_err_table_r() in the header file. (Addresses Debian
1001bug #204332)
1002
1003In the lib/et makefile, make sure com_err.info is deleted on "make clean".
1004
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04001005Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
1006present. This is for when we try stuffing an int into void * pointer.
1007
1008Fix type-punning which can cause gcc 3.x to miscompile code by getting
1009confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
1010and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
1011**'. The EVMS code uses an ugly union approach since we don't want to
1012modify the EVMS interfaces.
1013
1014Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
1015aid build process on systems can use invoke GNU make as "gmake".
1016
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05001017Added regression testing for mke2fs.
1018
1019Fixed gcc -Wall nitpicks.
1020
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001021Fixed various compiler warnings.
1022
1023Add portability fixes for FreeBSD and for using fsctl under Darwin to
1024support ext2 ioctl's.
1025

Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001027E2fsprogs 1.34 (July 25, 2003)
1028===============================
1029
1030Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
1031a tight loop while waiting for a child fsck to exit in some cases.
1032This burns CPU times which slows down the low-level filesystem check.
1033
1034Added code to mke2fs to assure that the default block size for a
1035filesystem is at least as big as the sector size of the device, if it
1036can be determined.
1037
1038Changed mke2fs and resize2fs to round the default size of a filesystem
1039to be an even multiple of the VM pagesize in order to avoid a Linux
1040kernel bug introduced when the storage of the buffer cache was moved
1041into the page cache.
1042
1043Mke2fs will warn the user when creating a filesystem with journaling
1044and a blocksize greater than 4096. (Addresses Debian bug #193773)
1045
1046Fixed a bug in resize2fs which caused it to fail on filesystems with a
1047non-empty bad block list. Resize2fs now discards any blocks on the
1048badblock list which are no longer part of the filesystem as the result
1049of a filesystem shrink. (Note: this means that shrinking and then
1050enlarging a filesystem is no longer a reversible operation;
1051information about bad blocks in the part of the filesystem which is to
1052be chopped off will be lost.)
1053
1054Changed resize2fs so the user can use prefixes to specify the units of
1055the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
1056and to make the error and informational messages explicitly display
1057the blocksize used by the filesystem, in order to avoid confusion.
1058(Addresses Debian bug: #189814)
1059
1060Added a new debugfs command, dump_unused, which dumps the contents of
1061all unused blocks to stdout. (Useful as an emergency try-to-find
1062deleted data command.)
1063
1064Added a new debugfs command, imap, which prints the location of a
1065specified inode in the inode table.
1066
1067Fixed a bug in the badblocks program which caused it to use one bit of
1068randomness in its non-destructive read/write test, instead of using a
1069full 8 bits of randomness.
1070
1071Added a new option (-t) to badblocks, which allows the user to control
1072the test pattern(s) used when checking a disk.
1073
1074The blkid probe function now more correctly detects UDF filesystems.
1075
1076Fixed a bug in the blkid library which caused it to not update its
1077cache if a filesystem changes from having a label to not having a
1078label.
1079
1080Fixed a bug in the blkid library wihch could avoid an infinite loop
1081in blkid_find_dev_with_tag() if /proc is not mounted and there the
1082/etc/blkid.tab file has not yet been created.
1083
1084Fixed the badblocks program so that the destructive read/write test
1085honors the -c option, and to use O_DIRECT when possible to avoid
1086thrashing the system block buffer cache.
1087
1088Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -04001089 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001090 - Removed testing NYC translation
1091 - Fixed NLS support for message abbrevations in e2fsck
1092 - Remove de-utf.po, since we shouldn't have two versions using different
1093 charset encodings.
1094 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
1095 simplify the statistics reporting in e2fsck.
1096
1097Changed configure.in so that its defaults for *BSD systems no longer
1098build an fsck wrapper, and not to install in /usr/local by default.
1099
1100Fixed some minor spelling errors/typo's in e2fsck and the configure
1101script.
1102
1103Fixed various Debian packaging issues (see debian/changelog).
1104
1105Updated and clarified man pages. (Addresses Debian Bug #195616)
1106
1107Programmer's notes:
1108-------------------
1109
1110Fix gcc -Wall nitpicks.
1111
1112Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
1113NLS support by default. (Added partial workaround for gettext/Darwin
1114incompatibility problems.)
1115
1116Added full MIT KRB5 and Himdall compaibility support to the com_err
1117library and the compile_et program. (Addresses Debian bug #191900)
1118
1119Added the blkid_known_fstype() function to the blkid library, which
1120returns true if it is passed a filesystem type which is recognized by
1121the blkid probing functions.
1122
1123Improved the documentation for the blkid library.
1124
1125Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
1126returns the hardware sector size of a device, if it is available.
1127
1128Added a dependency in the blkid library's .so file to the uuid
1129library, since the former uses the latter. (Addresses Debian bug
1130#194094)
1131
1132Added --with-diet-libc and --disable-evms to the configure script.
1133
1134Fixed a minor memory leak in the badblocks program.
1135
1136Fixed a portability problem in tune2fs --- not all systems have strptime().
1137
1138Fixed a portability problem in debugfs with the use of getopt() more
1139than once. Old-style BSD, new-style BSD, and Linux C libraries all do
1140things differently.
1141
1142Add support Windows support to ext2fs_get_device_size().
1143
1144Added (normally disabled) debugging code to the Unix I/O manager which
1145causes it to disable all userspace caching if the NO_IO_CACHE is
1146defined.
1147
1148Changed the test I/O manager so it can always be linked into e2fsck,
1149mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
1150configure script. The test I/O manager will only print any debugging
1151information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
1152variables are set, which specifies which I/O operations are logged and
1153a block number to watch, respectively. The log messages are sent to
1154stderr by default, unless a filename is specified via the
1155TEST_IO_LOGFILE environment variable.

Theodore Ts'o71df0dc2003-04-21 16:17:09 -04001158E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001159===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001160
Theodore Ts'oba142c12003-04-16 00:59:59 -04001161Added a new utility program, logsave, which captures the output of a
1162command in a log file, even if the containing directory hasn't been
1163mounted yet (in which case the it saves the output in memory until it
1164can write out the logfile). This is useful for capturing the
1165output of fsck during the boot sequence.
1166
1167Fixed some portability problems that were causing problems under
1168the Cygwin32 environment.
1169
1170Mke2fs now interprets a negative number to the -b option as a minimum
1171block size.
1172
1173Fixed a bug in mke2fs which was incorrectly checking the argument to
1174the -g option if the default block size was used. (Addresses Debian
1175bug #188319)
1176
1177Fsck now explicitly ignores tmpfs and devpts, and it will complain if
1178it can not find filesystem checkers for jfs, reseirfs, and xfs.
1179
1180E2fsck now updates the global free block and inode counters from the
1181block group specific counters quietly. This is needed for an
1182experimental patch which eliminates locking the entire filesystem when
1183allocating blocks or inodes; if the filesystem is not unmounted
1184cleanly, the global counts may not be accurate.
1185
1186Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
11872.0 is not yet supported; this only pulled in the bug fixes: fixed
1188possible hangs caused by bugs in calling waitpid, and not setting the
1189pipe to non-blocking mode; also fixed a file descriptor leak; made
1190sure all functions call log entry/exit functions.)
1191
1192Badblocks now flushes its output file as bad blocks are discovered.
1193
1194The uuid library is now more paranoid about assuming the correctness
1195of the /dev/random device; it mixes in a stream of bytes from
1196random/srandom, just in case.
1197
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001198Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04001199maintainer of e2fsprogs. Other various Debian-specific packaging
1200cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001201
1202Move the source tarball generation functions from the top-level
1203makefile to the util/gen-tarball script.
1204
1205Updated the Turkish .po translation file.
1206
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001207Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001208it more compatible with com_err libraries from those distributions.
1209
1210Changed dumpe2fs to always display the superblock fields relating to
1211the journalling and/or directory indexing feature even if those
1212features are not enabled.
1213
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001214Updated and clarify copyright statement vis-a-vis alpha releases of
1215e2fsprogs.
1216
1217The ss library will now try to dynamically link to the readline
1218library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04001219the debugfs program now has line editing and history features. The
1220SS_READLINE_PATH environment variable is used to find a readline or
1221readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001222
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001223E2fsck now finds most duplicate filenames (all when rebuilding all
1224directories via the -D option) and offers to delete or rename
1225duplicate filenames/directory entries. (Addresses Debian Bug #176814).
1226
1227Fix bug in e2image. When writing out a raw image file, include data
1228blocks from symlinks that do not store the symlink within the inode.
1229
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001230Fix bug in resize2fs which incorrectly moved the block and inode
1231bitmaps for sparse superblock filesystems and incorrectly marked
1232blocks as in use. (Addresses Debian bug #174766)
1233
1234Added a new shared library, the blkid library, which efficiently
1235allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
1236and UUID filesystem specifiers without needing to search all of the
1237devices in the system. Instead, the device is looked up in a cache
1238file, and then verified to make sure the blkid cache is correct.
1239
1240Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
1241the device name, using the blkid library. (Addresses Debian bugs
1242#166048, #179671)
1243
1244Fsck now supports backslash escapes in /etc/fstab so that \040 can be
1245used for spaces in device labels.
1246
1247Removed 32-bit limitations for debugfs's dump command.
1248
1249If the user specifies a large number of inodes, Mke2fs will
1250automatically adjust the number of blocks per group to find a valid
1251set of filesystem parameters.
1252
1253Add workaround to detect broken MD devices where when some of the
1254underlying devices are marked read-only, writes to the MD device are
1255silently dropped. E2fsck will detect if there is an attempt to run
1256the journal twice, and abort with an error if this is the case.
1257(Addresses IBM Bugzilla bug #1226)
1258
1259E2fsck will print an error if more than one of the -p/-a, -n or -y
1260options are specified.
1261
1262E2fsck will fix HTREE corruptions in preen mode, without stopping the
1263boot process. This is needed because the 2.4 ext2 filesystem
1264accidentally had the INDEX_FL backwards compatibility code removed.
1265
1266Mke2fs no longer creates filesystems with the dir_index flag set by
1267default; the user has to specifically request it.
1268
1269Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04001270#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001271
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001272Created man page for the mk_cmds program (from the libss library).
1273
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001274Programmer's notes:
1275-------------------
1276
1277Fix various gcc -Wall nits.
1278
1279Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001280successfully under Solaris and Apple/Darwin.
1281
1282Fixed a Makefile dependency to allow building e2fsprogs using parallel
1283make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001284
1285Changes to create a subset distribution which consists only of the
1286et, ss, uuid, and blkid libraries. The configure script and top-level
1287makefile were changed to support working with a subset distribution.
1288
Theodore Ts'oba142c12003-04-16 00:59:59 -04001289Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
1290actually used, and might people who are looking for
1291EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
1292
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001293Updated debian files to fix a number of Lintian warnings.
1294
1295Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001296
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04001297Removed unnecessary libraries from being linked into the fsck, lsattr,
1298chattr, and blkid executables.
1299
Theodore Ts'o38513012002-11-09 15:00:56 -05001300E2fsprogs 1.32 (Nomvember 9, 2002)
1301==================================
1302
1303Fixed a bug in the Unix I/O routines which caused needless writebacks
1304of clean blocks from the unix_io cache (they were erroneously marked
1305as being dirty, so they were getting written back to disk before
1306getting evicted from the disk cache). This was harmless, but it
1307significantly slowed down e2fsck.
1308
1309Made some other minor optimizations to the Unix I/O routines to save a
1310small amount of CPU time.
1311
1312Updated internationalization files.
1313
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001314
Theodore Ts'oae65b292002-11-08 20:08:48 -05001315E2fsprogs 1.31 (Nomvember 8, 2002)
1316==================================
1317
1318Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
1319compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
1320handling for child process that die unexpectly. Add a hack to force
1321mkfs to create filesystems that won't cause problems with hardware
1322that has 2k or 4k minimum blocksize requirements. Read from child
1323processes in non-blocking mode, so that the GUI continues to update.
1324
1325Fix e2fsck so that it returns the appropriate exit code when the root
1326filesystem has been changed, so that system's rc scripts will be told that
1327the system needs to be rebooted.
1328
1329Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
1330was set, some of the descriptor blocks that should have been written
1331out were getting skipped.
1332
1333Changed e2fsck to force out changes to the backup copies of the
1334superblock and block group descriptors when important changes are made
1335to those data structures.
1336
1337Fix a bug where e2fsck could erroneously mark a filesystem as being
1338clean if a check of dirty filesystem is interrupted with a ^C. (Bug
1339introduced in e2fsprogs 1.28.)
1340
1341If journal debuging is enabled using --enable-jbd-debug, the debugging
1342level is now set via the E2FSCK_JBD_DEBUG environment variable.
1343
1344If byteswapping support is disabled using configure --disable-swapfs,
1345skip the tests which depend on byte-swapping, so that "make check"
1346won't bomb out.
1347
1348Lshattr will now display the indexed directory flag. Also, some of
1349the more esoteric compression flags are supressed unless compression
1350support has been enabled.
1351
1352Update man pages.
1353
1354
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001355E2fsprogs 1.30 (October 31, 2002)
1356=================================
1357
1358When resizing a filesystem, and inodes need to moved, resize2fs will
1359update the inode's ctime field, and the mtime field of the containing
1360directories, so that incremental backups using dump/restore will work
1361correctly.
1362
1363In order to avoid spurious errors, e2fsck wil check the last
1364superblock write time to determine whether or not it can safely use
1365the LOW_DTIME checks to determine if there are inodes on the orphan
1366inode linked list that had somehow gotten disconnected. (Addresses
1367Sourceforge bug #620980)
1368
1369Partition in /proc/partitions that being with the string "lvm" are
1370considered real partitions even if they do not end with a number.
1371
1372Fixed a bug in the the uuid generation function, where if /dev/urandom
1373is not present, but /dev/random is, and there isn't sufficient
1374entropy, the get_random_byte function could spin a loop forever.
1375
1376E2fsck, mke2fs, etc. will now reliably notice when image files are
1377mounted using the loopback interface. (Addresses Sourceforge bug
1378#619119)
1379
1380When flushing buffers (as is done by badblocks, for example) check to
1381see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
1382FDFLUSH ioctl which causes the MD device driver which causes confusing
1383syslog messages about obselete ioctl messages. (Addresses Sourceforge
1384bug #545832).
1385
1386Debugfs's write command now checks to see if the destination filename
1387exists before creating it. (Addresses Sourceforge bug #478195.)
1388
1389When installing man pages, search for compressed man pages using all
1390commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
1391
1392Fixed a bug in fsck where multiple filesystems specified on the
1393command were not being checked in parallel due to a logic bug
1394introduced to support the FSCK_MAX_INST environment variable.
1395
1396We have added a new superblock field, s_mkfs_time, which indicates
1397when a filesystem was created. It is set via mke2fs, and printed out
1398by dumpe2fs, but is not actually touched by the kernel.
1399
1400Dumpe2fs has been made more robust by not aborting if there is an
1401error reading the block/inode bitmaps; instead it will still print out
1402the location of the block/inode bitmaps and inode table.
1403
1404Add support for the an alternative block group descriptor layout which
1405allows for on-line resizing without needing to prepare the filesystem
1406in advance. (This is the incomat feature flag meta_bg.)
1407
1408Add support for storing default mount options in the superblock, so
1409that the filesystem can be mounted with specific mount options without
1410needing to specify them on the mount command line or in the /etc/fstab
1411file.
1412
1413Add support for a new inode flag, which is to be used for indicating
1414the top of directory hierarchies for the Orlov block allocator.
1415
1416Fix e2fsck so that if it creates the lost+found directory, it does so
1417with the more apporpriate permissions of 0700. Also change
1418mklost+found so that it also creates the directory 0700.
1419
1420Fixed format bug in e2fsck if NLS is in use.
1421
1422Add a German translation for e2fsprogs's NLS support.
1423
1424Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
1425the beginning of the inode table. This won't matter much, since if
1426there is a bad block at the beginning of the inode table, the root
1427directory won't be available. But at least e2fsck won't crash in this
1428case.
1429
1430Fixed endian problems in the htree code for e2fsck and debugfs.
1431
1432When byte-swapping a filesystem on a PPC architecture, byte-swap the
1433bitmaps since the historical big-endian ext2 variant had byte-swapped
1434bitmaps, and the ext2fs library assumes this. This fixes the
1435regression test suite on PPC machines.
1436
1437Fix e2image so that it handles a bad block in the inode table
1438appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04001439
1440E2fsck now uses a more sophisticated algorithm to salvage corrupted
1441directories that recovers more information in the corrupted directory
1442block.
1443
1444E2fsck now performs additional consistency checks on indexed (HTREE)
1445directories.
1446
1447Fix bug where efsck might get confused about whether a completely
1448empty directory block is an empty leaf block or an interior htree
1449node. This could cause e2fsck to get confused into think that a valid
1450indexed directory was corrupted.
1451
1452E2fsck no longer creates an empty directory entry at the end of a
1453directory block when optimizing a directory. This would cause some
1454earlier versions of the dxdir kernel code to corrupt the directory
1455when attempting to split a node containing an empty directory entry.
1456
1457E2fsck could sometimes in rare circumstances leave the indexed flag
1458set after a small directory was optimized by compressing it instead of
1459indexing it. (This should never happen in real life, since
1460directories that small wouldn't have been indexed, but better safe
1461than sorry.)
1462
1463E2fsck now only updates the master superblock in all cases. This
1464slightly shortens its run time.
1465
1466Ext2ed can deal with directory entries of length 0; previously it
1467would get stuck in an infinite loop.
1468
1469Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
1470specifiers. (Sourceforge patch #613447)
1471
1472Badblocks will now work correctly on read-only devices such as
1473CD-ROM's. (Sourceforge patch #600451)
1474
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001475Updated and clarified man pages. (Addresses Debian bug #167108)

1477
Theodore Ts'oc6633052002-09-24 01:26:50 -04001478E2fsprogs 1.29 (September 24, 2002)
1479===================================
1480
1481Fixed a bug in e2fsck which could corrupt a directory when optimizing
1482it (via the -D option) or rebuiliding the hash tree index with a 1 in
1483512 probability, due to a fence post error.
1484
1485Fixed a bug in the LVM support code which caused LABEL='xxx' not to
1486work correctly.
1487
1488Mke2fs now enables the directory indexing flag by default. (Since
1489this is a compatible feature flag, it's safe to do so.)
1490
1491Tune2fs will support setting the directory indexing feature flag. It
1492will automatically set up the default hash algorithm and hash seed
1493fields in the superblock.
1494
1495If the bone-headed user enters the root filesystem twice in
1496/etc/fstab, the -R option which skips the root filesystem will skip
1497all of them. (Addresses Debian bug #159423). Note! This is not a
1498precedent for dealing intelligently with any other kind of doubled
1499entry in /etc/fstab!
1500
1501
1502Programmer's notes:
1503-------------------
1504
1505Removed perror declaration in lib/et/internal.h. All modern systems
1506can be expected to define perror() these days. Besides, the lib/et
1507code wasn't using perror at all anyway. :-)
1508
1509
Theodore Ts'ob7bad612002-08-31 03:00:33 -04001510E2fsprogs 1.28 (August 31, 2002)
1511================================
1512
1513Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
1514for setting the htree flag is not included yet, although it can be
1515manually turned on via the debugfs program.
1516
1517Clarified e2fsck error message which is printed when it cannot find
1518sufficient contiguous block when relcating filesystem metadata.
1519
1520Added support for building an EVMS plugin module for ext2/3. This
1521module is substantially the same as the EVMS module shipping with EVMS
15221.1, with one or two bugfixes. E2fsprogs can also build this plugin
1523for use with EVMS 1.0 (which did not include the ext2 plugin module),
1524if the configure --enable-old-evms flag is given.
1525
1526Fsck will search through EVMS volumes when trying to resolve
1527filesystem specifications such as LABEL=xxx or UUID=xxx.
1528
1529Added a new utility program, /sbin/findfs, which will return
1530filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
1531the device name.
1532
1533Update and clarified various man pages. (addresses Debian Bug #145044,
1534#146437, #131350, #151990, #144621, #141938)
1535
1536If there are no filesystems specified on fsck's command line, fsck now
1537treat that as if the -As options were given. Previously it would
1538simply do nothing. (Addresses Debian Bug #153102)
1539
1540Mke2fs no longer treats a failure to be able to clear the MD signature
1541at the end of the filesystem as a fatal error. (Addresses Debian Bug
1542#155007)
1543
1544The e2p library functions (which are used by lsattr and chattr) now
1545double check to make sure the file is a regular file or directory
1546before attempting to use the ext2 ioctls. Some device drivers
1547unfortunately respond to the ext2 ioctl's with unknown behaviour.
1548(Addresses Debian Bug #152029).
1549
1550The extended attribute handling has been updated to correspond with
1551the latest V2 bestbits ACL code.
1552
1553Fixed bug in e2fsck which caused it to not clear the dtime field when
1554processing truncated inodes on the orphan list. This could cause data
1555loss(!) if a filesystem is rebooted before a truncate has been
1556committed.
1557
1558E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
1559algorithms. This makes e2fsck much faster in the case of severely
1560corrupted filesystems where a large number of blocks are claimed by a
1561large number of inodes. (Thanks to the 2.5 IDE device driver for
1562inspiring this work.)
1563
1564Resize2fs has been significantly sped up when shrinking and expanding
1565a filesystem by a very small number of blocks (for example, when EVMS
1566is converting a partition to be an EVMS legacy volume).
1567
1568Added a new option to e2fsck, -D, which will optimize or compress all
1569of the directories in the filesystem.
1570
1571E2fsck now catches SIGINT and SIGTERM to make sure it will can
1572properly clean up and only exit at safe points. Fsck will pass
1573SIGINT/SIGTERM to its child processes, and wait until they have all
1574exited before it exits.
1575
1576The uuid parsing code in the uuid library now properly complains when
1577an illegally formated uuid is presented to it. (Addresses Debian bug
1578#152891)
1579
1580Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
1581and 2.4.17, since the workaround can cause problems when using a 2.4
1582kernel with an old version of glibc built with the 2.2 headers.
1583
1584Fixed a bug in mke2fs where it wasn't properly clearing the initial
1585superblock used by other filesystems. (Addresses Debian bug #147256.)
1586
1587Added support for the synchronous directory feature written by Andrew
1588Morton.
1589
1590The debugfs program can delete directories using the rmdir command.
1591
1592Add support for 8k and 16k filesystems (for systems with page sizes
1593that are greater or equal to 8k or 16k, respectively). Note that
1594these filesystems can not be mounted on x86 systems, or other systems
1595with only 4k page sizes, due to limitations in the current Linux VM
1596code.
1597
1598Resize2fs requires that the filesystem state be valid and have no
1599errors; otherwise, e2fsck -f must be run first. (Previously it simply
1600required that the last fsck time be greater than the last mount time.)
1601
1602Configure now defaults the man pages directory to /usr/share/man on
1603Linux systems.
1604
1605E2fsck now offers to truncate inodes which contain too many blocks (so
1606that i_blocks would overflow. Also fixed handling of large sparse
1607files.
1608
1609E2fsck now more completely checks for symlink validity, including
1610requiring NULL termination and length checks.
1611
1612E2fsck will offer to try forcing a disk write to remap a bad block
1613after finding a read error when reading a filesystem metadata block.
1614
1615Fixed a bug in debugfs which caused the -b and -s options to crash
1616debugfs, as well as breaking the testb, setb, and clearb functions.
1617
1618Added a bmap command to debugfs which calculates the logical to
1619physical block mapping for a particular inode.
1620
1621Fixed a bug in code which checked to see if a device was mounted which
1622sometimes (rarely) failed in the case of a plain file.
1623
1624Fixed a bug in resize2fs where when it reported an error, it would
1625print a message erroneously indicating that the filesystem had been
1626resized before it aborted.
1627
1628When resizing a plain file which is smaller than the requested size,
1629resize2fs will attempt to extended the file so that programs like
1630e2fsck will not complain that the file is too small.
1631
1632Resize2fs will print the actual new size of the filesystem when it is
1633finished resizing.
1634
1635Fixed a bug in debugfs where "ls -l" would report incorrectl file type
1636information on big-endian systems.
1637
1638
1639Programmer's notes:
1640-------------------
1641
1642Fixed collisions with C++ reserved words.
1643
1644Added portability fixes for building e2fsprogs on the HURD and AIX.
1645
1646Added the ext2ed program for creation of test cases. (ext2ed has many
1647limitations and bugs which make it unsuitable for production use.)
1648
1649The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
1650flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
1651name_len field is byte swampped on big-endian machines, since in the
1652V2 structure, name_len is a char field which is doesn't need to be
1653byte swapped --- except if an old-style kernel had byte-swapped the
1654name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -05001657E2fsprogs 1.27 (March 8, 2002)
1658==============================
1659
1660The warning messages for mke2fs now go to standard error.
1661
1662Fixed to make sure "make check" runs all of the test programs with
1663LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
1664
1665The mke2fs program checks the boot sector for the BSD disk label, and
1666avoids erasing it if it is there.
1667
1668Fixed a bug in e2fsck which caused it to core dump if the journal
1669inode was missing when it was supposed to be there.
1670
1671E2fsck now prints ranges in pass 5 when printing deltas for the block
1672and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001673
1674Debugfs's "ls -l" command now will print out the file type information
1675in the directory entry.
1676
1677Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
1678mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
1679
1680Debugfs can now examine the experimental directory indexing
1681information.
1682
Theodore Ts'oa471ac52002-03-05 03:37:06 -05001683Fixed bug in debugfs which caused it to core dump if modify_inode is
1684called without an open filesystem.
1685
1686The debugfs lsdel command now runs its output through a pager first.
1687
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001688When installing manual pages, remove the compressed manual pages first.
1689
1690Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
1691
1692Fix the 2.4 resource limitation workaround introduced in 1.26 which
1693actually broke things on mips32, sparc32, and Alpha platforms.
1694
Theodore Ts'oa471ac52002-03-05 03:37:06 -05001695Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
1696(which is required by the newer libintl libraries).
1697
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001698Programmer's notes:
1699-------------------
1700
Theodore Ts'oa8e77242002-03-08 03:12:14 -05001701Fixed various gcc -Wall complaints.
1702
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001703Fixed a few memory leaks in the e2fsck journaling code, and in the
1704ismounted code checking for a swap device.
1705
1706Add new inode I/O abstraction interface which exports an inode as
1707an I/O object.
1708
1709Exported ext2_file_flush as a public interface.
1710
1711In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
1712
1713Lots of small random portability fixes to make e2fsprogs build under
1714AIX --- even without the 5L compatibility toolkit, and even using the
1715uber-crippled AIX native C compiler.
1716
1717
Theodore Ts'o06987392002-02-03 01:36:54 -05001718E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001719=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001720
Theodore Ts'o446314f2001-12-24 15:22:27 -05001721Dumpe2fs will keep going now if the bad block inode can't be read.
1722(Previously it stopped with a fatal error.)
1723
1724E2fsck will now give an opportunity to run the journal even if the
1725recovery flag is not set. This is the default behaviour if e2fsck is
1726using a backup superblock, since the needs_recovery flag will never be
1727set in the backup superblock copies.
1728
1729E2fsck now automatically finds the backup superblock/group descriptors
1730even when the primary superblock is completely destroyed for 2k and 4k
1731filesystems. (Previously it just guessed/assumed that we were dealing
1732with a 1k filesystem in that case, and users had to manually specify
1733the backup superblock number.)
1734
1735Fixed a bug in e2fsck where it dereferences a null pointer when there
1736is a problem opening a filesystem in preen mode.
1737
1738E2fsck now handles external journals correctly; previously it trashed
1739the external journal device if the journal needed to be replayed.
1740
1741Work around ulimit incompatibility problem caused by recent 2.4
1742kernels; the unix IO module will automatically try to set any resource
1743limits to be infinite on startup.
1744
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001745Fixed a bug in e2fsck where it wasn't allocating a new block or inode
1746bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001747 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001748
1749E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
1750clearing the new V2 fields if they do not make sense or if the ext3
1751superblock is version 1 superblock.
1752
1753E2fsck will automatically relocate the ext3 journal from a visible
1754file (i.e., /.journal) to an hidden inode if the filesystem has been
1755opened read/write. This allows the users to add a journal while the
1756filesystem is mounted, but the next time the system is rebooted, the
1757journal file will disappear. This avoids problems with backups,
1758stupid operators with superuser bits, etc.
1759
1760Fix a bug in fsck where it would not support a filesystem type of
1761"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
1762
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001763Fsck now supports fstab entries of the form "ext3,ext2". It will also
1764automatically identify reiserfs filesystems.
1765
1766The number of processes spawned by fsck can now be limited using the
1767FSCK_MAX_INST environment variable.
1768
Theodore Ts'o446314f2001-12-24 15:22:27 -05001769Fsck now searchs the LVM proc hierarchy to find logical volumes which
1770should be searched for UUID and label information.
1771
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001772Work around a bug in 2.4.10+ kernels by trying to unset the filesize
1773limit if at all possible, when opening a block device. (The filesize
1774limit shouldn't be applied against writes to a block device.)
1775
Theodore Ts'o446314f2001-12-24 15:22:27 -05001776In mke2fs and e2fsck, specifying the -c option twice will now do
1777a read/write test on the disk. Update the man pages to encourage
1778using the -c option, and to discouraging running badblocks separately,
1779since users tend to forget to set the blocksize when running
1780badblocks.
1781
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001782Mke2fs now automatically clears the immutable attribute on a
1783pre-existing .journal file left over from a previous failed attempt to
1784add a journal to an alreadyy-mounted filesystem.
1785
1786Fixed mke2fs's exit codes to consistently indicate when the mke2fs
1787operation failed.
1788
Theodore Ts'o446314f2001-12-24 15:22:27 -05001789Mke2fs now creates the lost+found directory with permissions of 0700,
1790so that files that had previously lived in protected directory are
1791safe if they get dropped in lost+found and the system administrator
1792doesn't deal with immediately. (Addresses Debian #bug 118443)
1793
1794Mke2fs and e2fsck (and all programs that use the
1795ext2fs_check_if_mounted function) will now properly identify that a
1796device is mounted, even in cases where devfs has confused things with
1797multiple devices names with the same identity, or if a dim-witted
1798system administrator has done something stupid like creating device
1799file aliases in their home directory. Also now checks for swap devices
1800by using /proc/swaps. (Addresses Debian bug #106622)
1801
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001802Added a new option (-T) to tune2fs which sets the time a filesystem
1803was last checked.
1804
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001805Speed up e2image when creating sparse raw image files by optimizing
1806away excess lseek() system calls.
1807
1808Fix support of large (> 2GB) files when used as a filesystem in
1809mke2fs, tune2fs, debugfs, and findsuper.
1810
1811Debugfs's stat and icheck commands now properly deals with large (>
18122GB) files.
1813
1814Debugfs's set_super_value command now prints out the list of valid
1815superblock fields which can be set using the command.
1816
Theodore Ts'o446314f2001-12-24 15:22:27 -05001817Debugfs's rm and kill_file command now updates the superblock free block
1818and inode counts, thus keeping the filesystem consistent.
1819
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001820Debugfs's lsdel command now takes an optional argument which allows
1821the user to only see the most recently deleted files.
1822
1823A new command (undel) was added to debugfs which automates
1824undeleting a deleted inode and linking it back to a directory.
1825
1826Debugfs's ls command now takes a new option, -d, which lists
1827deleted directory entries.
1828
1829Debugfs's testb, freeb, setb, and find_free_block commands now take an
1830optional count argument.
1831
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001832Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
1833be used to signal that a particular inode should not be eligible for
1834tail-merging --- this is needed for programs like LILO.
1835
1836The findsuper (an unreleased, uninstalled utility program) has been
1837improved to add extra validity checks and to add a progress meter.
1838(It is still an unsupported program; the officially supported way to
1839recover from a trashed partition table is to use gpart; findsuper is
1840for wizards only. :-)
1841
1842Debugfs was fixed to compile with "configure --disable-swapfs".
1843
Theodore Ts'o446314f2001-12-24 15:22:27 -05001844Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001845
1846Added new translation file for Turkish.
1847
Theodore Ts'o446314f2001-12-24 15:22:27 -05001848Programmer's notes:
1849-------------------
1850
1851Fix general gcc -Wall complaints.
1852
1853E2fsprogs (mostly) works with the dietlibc.
1854
1855The programming texinfo file has been expanded to include description
1856of additional libext2fs functions. (Still not compeltely done, but a
1857lot of the more important functions have been documented.)
1858
1859Added a umask structure to struct_ext2_filsys, which currently only
1860modifies the behaviour of ext2fs_mkdir(), but if we add any file
1861creation functions to libext2fs, we should also make sure they respect
1862the umask setting.
1863
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001864The build-rpm script was fixed to be a bit more safe.
1865
1866The tests' Makefile now has a way of automating test case creation
1867for e2fsck, using "make testnew".
1868
1869Created a new function, ext2fs_dir_iterate2 which passes more
1870information to the callback function (identical to the one used by
1871ext2fs_dblist_dir_iterate). The directory iterator functions take a
1872new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
1873directory entries. If the directory entry is deleted, the callback
1874function will be called with the entry paraemter set to
1875DIRENT_DELETED_FILE.
1876
1877Added new functions, ext2fs_inode_alloc_stats and
1878ext2fs_block_alloc_stats, which takes updates block/inode allocation
1879statistics in the bitmaps, block group descriptors, and superblock
1880when inodes or blocks are allocated or deallocated.

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04001883E2fsprogs 1.25 (September 20, 2001)
1884===================================
1885
1886This is primarily a bug-fix release; no new features were added, but
1887there are a number of embarassing bug fixes and cleanups applied.
1888
1889Fix a bug mke2fs which causes stack garbage to be written to disk when
1890zapping disk sectors. (This bug could cause mke2fs to core dump for
1891some kernels, I suspect with security enhancement patches.)
1892
1893Remove unneeded #include of <linux/config.h> which was breaking
1894building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
1895
1896Updated tune2fs man page to reflect the fact that adding or removing a
1897journal doesn't require running e2fsck.
1898
1899Remove use of AC_REQUIRE from autoconf which had been used to prevent
1900AC_CANONICAL_HOST from being called twice; unfortunately this causes
1901recent autoconf to bomb out since they don't allow AC_REQUIRE to be
1902used outside of autoconf macros. Fortunately, it doesn't seem to be
1903necessary any more, anyway.
1904
1905E2fsck will now not fall back to an alternate superblock if the user
1906specifies the superblock location explicitly on the command-line.
1907This allows easier recovery from a situation where the primary
1908superblock and block groups are slightly corrupted, but the backup
1909superblocks are completely broken.
1910
1911Fix problem which caused compile_et and mk_cmds to blow up if
1912e2fsprogs was in a directory with a pathname that contained spaces.
1913
1914We are now more paranoid about checking the entry in /etc/mtab to make
1915sure the filesystem is really mounted, since some broken distributions
1916(read: Slackware) don't initialize /etc/mtab before checking non-root
1917filesystems. (Slackware also doesn't check the root filesystem
1918separately, and reboot if the root filesystem had changes applied to
1919it, which is dangerous and broken, but there's nothing I can do about
1920that.)
1921
1922Make UUID library C++ friendly by adding appropriate extern "C"
1923declarations and using const in the function declarations.
1924
1925Fix up the com_err texinfo file so that it can product a valid info
1926file (previously, it could only be used to generate paper
1927documentation using texinfo.tex).
1928
1929
Theodore Ts'ofb707752001-09-04 15:00:37 -04001930E2fsprogs 1.24a (September 2, 2001)
1931===================================
1932
1933Fix brown-paper bug in mke2fs which caused it to segfault when
1934printing the version string.
1935
1936
Theodore Ts'o109624a2001-08-31 00:59:55 -04001937E2fsprogs 1.24 (August 30, 2001)
1938================================
1939
1940Revert the BLKGETSIZE64 support, since for some distributions, this
1941ioctl has been used by an unofficial kernel patch to update the last
1942sector on the disk, and this was causing disk corruption problems as a
1943result.
1944
1945Mke2fs is now more careful about zapping swap space signatures and
1946other filesystem/raid superblock magic values so that programs like
1947mount who try to use hueristics to determine the filesystem type of a
1948partition are less likely to be confused.
1949
1950E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
1951regular file (since Andreas Dilger's on-line resizing tools will set
1952its mode bits).
1953
1954Fixed some minor texinfo, man pages nits for spelling errors,
1955texinfo warnings, etc. (Addresses Debian bug #110621.)
1956
1957E2fsprogs program no longer print the filesystem version number
1958(i.e. 0.5b), since it only confuses people and doesn't serve any real
1959purpose.
1960
1961E2fsck will once again compile under libc5, since it will supply its
1962own version of strnlen if necesssary.
1963
1964mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
1965when specifying the external journal device. tune2fs will also search
1966devices looking for the externla journal debice when removing.
1967
1968E2fsprogs 1.23 (August 15, 2001)
1969================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001970
1971Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04001972correctly handle a filesystem with EA's and check the EA blocks for
1973corruptions.
1974
Theodore Ts'od494bba2001-08-09 06:14:42 -04001975E2fsck's symlink sanity checking has been cleaned up. It now checks
1976the i_size value of fast symlinks, and checks for immutable flags
1977being set of symlinks, etc.
1978
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001979E2fsck now offers to clear inodes which are special files that have a
1980non-zero i_blocks or i_size field. (The i_size field check was in the
1981previous version of the code, but due to a bug it didn't offer to
1982clear the inode unless i_size and i_size_high were both non-zero.)
1983
Theodore Ts'od494bba2001-08-09 06:14:42 -04001984E2image can now create "raw" image files, which only contain the
1985filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
1986debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001987
1988Add support for the 64-bit block device patches.
1989
1990Fixed bugs in creating external journals with a 1k blocksize.
1991
Theodore Ts'od494bba2001-08-09 06:14:42 -04001992Add initial support for external journals (so long as the external
1993journal only supports a single filesystem) in e2fsck.
1994
1995Remove requirement for needing to run fsck on a filesystem after
1996removing a journal (either internal or external).
1997
Theodore Ts'obf16d102001-07-27 22:20:06 -04001998The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001999
2000Speed up the check of an ext3 filesystems by avoiding a needless flush
2001of all of the superblock and block group descriptors.
2002
Theodore Ts'od494bba2001-08-09 06:14:42 -04002003Speed up creating an internal journal using tune2fs in the case where
2004the filesystem has a lot blocks already allocated.
2005
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002006Tune2fs has been fixed to make sure that only error messages go to
2007stderr, and normal message go to stdout. (Addresses Debian bug #108555)
2008
Theodore Ts'od494bba2001-08-09 06:14:42 -04002009Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002010now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04002011
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04002012Add support in fsck for the filesystem type "auto".
2013
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002014Fsck -A will not try to interpret device names for filesystems which
2015have a pass number is 0. (Addresses Debian bug #106696).
2016
2017Fsck prints a warning message if now valid filesystems are passed to
2018it. (Addresses Debian Bug #107458.)
2019
Theodore Ts'o9249d982001-07-20 18:14:10 -04002020E2fsck now gives an explicit warning if there filesystem still has
2021errors at the end of the run. (Addresses Debian bug #104502)
2022
Theodore Ts'od494bba2001-08-09 06:14:42 -04002023E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04002024reflects an error. E2fsck will also not run the orphan list if the
2025filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04002026
2027E2fsck now prints the number of large files when given the -v option.
2028

Theodore Ts'o19d6b542001-06-23 00:13:09 -04002034E2fsprogs 1.22 (June 22, 2001)
2035==============================
2036
2037Fixed a bug in e2fsck's handling of orphan inodes which are special
2038files (i.e., block/character device files, named FIFO's, etc.).
2039
2040Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
2041tune2fs to fail at adding a journal to a mounted filesystem.
2042
2043Fixed a few big-endian bugs in e2fsprogs
2044 * The directory block functions were accidentally reporting
2045 some directories as corrupted when they weren't.
2046 * If e2fsprogs is compiled --disable-swapfs, the C language
2047 equivalents weren't being included for big-endian platforms.
2048 (Fixes Debian bug #101686).
2049
2050Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
2051
2052Programmer's notes:
2053-------------------
2054
2055Use platform independent method of defining the BLKFLSBUF and FDFLUSH
2056ioctls, and allow them to be defined for non-i386 platforms.
2057
2058The uuid.h header file is now protected against multiple inclusions.
2059
2060E2fsprogs is now being developed using BitKeeper. Changed the test
2061scripts to deal with BK's stripping CR characgters from text files,
2062and changed the top-level Makefile.in to avoid including BitKeeper
2063files when generating the source tarball.
2064
2065
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002066E2fsprogs 1.21 (June 15, 2001)
2067==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00002068
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002069Added new configure flags which allow a subset e2fsprogs to be built;
2070this is most useful for boot floopies, since the resulting shared
2071libraries and programs are slimmed down by removing features that
2072aren't necessary for a boot floppy. The new flags that were added
2073are: --disable-swapfs, which removes support for byte swapping old
2074legacy PPC/68k filesystems, --disable-debugfs, which removes support
2075for debugfs from the libext2fs library, --disable-imager, which
2076removes support for the e2image program, and --disable-resizer, which
2077removes support for resize2fs.
2078
2079E2fsck now prints the number of mounts or days elapsed since the last
2080check when e2fsck is forced to check an otherwise clean filesystem.
2081
2082Tune2fs now prints an informative message about how often a filesystem
2083will be checked when adding a journal to the filesystem, to remind the
2084user that he/she may want to adjust those parameters using tune2fs
2085-c/-i.
2086
2087Worked around hurd brain-damage which causes e2fsck to sometimes
2088believe a filesystem is the root filesystem based on device numbers
2089(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
2090violation).
2091
2092Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
2093erroneous error with the -F option was specified.
2094
2095Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002096ext3 0.7a.
2097
Theodore Ts'o767de092001-06-02 01:20:18 +00002098Fixed two bugs in e2fsck's handling of dup block handling, dealing
2099with relatively uncommon edge cases: a directory with an indirect
2100block which is claimed by another file, and when the last inode in the
2101filesystem has blocks claimed by another file.
2102
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00002103E2fsck now checks to see if the i_size field of a fast symlink is too
2104big, and offers to clear the symlink if so.
2105
2106E2fsck now checks to see if i_size_high of special files is non-zero,
2107and offers to clear i_size_high.
2108
Theodore Ts'o767de092001-06-02 01:20:18 +00002109Fix e2fsck's handling of incompatible journal flags so that the user
2110has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00002111entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00002112
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002113Fixed a bug in fsck which could cause it to core dump if a mix of
2114standard and non-standard device names are used in /etc/fstab.
2115(Debian bug #100559)
2116
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002117Fixed a bug in debugfs which caused read errors when copying a file to
2118not be noticed.
2119
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002120The debugfs set_super_value command can now modify the s_lastcheck field.
2121
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002122Fixed a bug in lsattr and chattr which was accidentally introduced in
21231.20 to support > 2GB files; both lsattr and chattr wasn't reading
2124directories correctly because the change modified the layout of struct
2125dirent to be incompatible with the libe2p shared library.
2126
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002127Cleaned up the mke2fs manual page and included a discussion about why
2128it's good to periodically check the filesystem even when journaling is
2129enabled.
2130
Theodore Ts'o767de092001-06-02 01:20:18 +00002131Programmer's notes:
2132-------------------
2133
2134Fix general gcc -Wall complaints.
2135
2136The types needed by the ext2 header files are now provided by
2137lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
2138
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002139Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002140in ext2_types.h. Also, if linux/types.h has already been defined,
2141don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002142
Theodore Ts'o767de092001-06-02 01:20:18 +00002143Fixed make depend script so that it automatically corrects the
2144pathname cleanups performed by make -M, so I don't have to fix them up
2145by hand.
2146
2147Fixed the d_loaddump test case to be more robust, and not depend on
2148bash'isms.
2149
2150Removed debugfs's dependence on pread(), which was accidentally
2151intrudced in e2fsprogs 1.20
2152
Theodore Ts'oc05b5522001-06-08 12:03:36 +00002153Fixed a performance bug in the libext2fs's icount routine; the size
2154estimate of the icount array was incorrectly being calculated.
2155
Theodore Ts'ob90b8262001-06-15 22:54:34 +00002156Removed use of the badblocks compatibility functions in the e2fsprogs
2157programs.
2158
2159Added paranoia code which protects against strange cases where /etc
2160isn't on the root filesystem, or if /etc/mtab doesn't exist.
2161
2162The header file ext2_types.h is now installed.
2163
2164Autoconf is used to determine when we are on big-endian machines,
2165instead of doing run-time tests, to save a few bytes of code.
2166
2167The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
2168functions are no longer inline functions, which saves space and
2169doesn't really cost any real performance.
2170
2171The ext2fs library no longer depends on the e2p library. (What need
2172there was of it --- namely, fsetflags, was coded in-line).
2173
2174Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
2175when the user is stupid and tries compiling the package using "make
2176install" as root.
2177
2178Miscellaneous code cleanups:
2179 * Added missing files from Makefile.in's SRCS file, so that
2180 their dependencies would be properly calculated.
2181 * Removed redundant code
2182 * Fixed comments in code
2183 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002186E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002187=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00002188
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002189Add support for replaying the ext3 journal purely in user mode,
2190including handling the orphaned inode list. Used code contributed by
2191Andreas Dilger, with bug fixes and the orphaned inode handling done
2192by Theodore Ts'o.
2193
2194The mke2fs and tune2fs programs can create or modify a filesystem to
2195include an ext3 journal. Tune2fs also can be used to remove an ext3
2196journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002197
2198E2fsck will now check for the existence of a linked list of orphan
2199inodes in the superblock, and clear those inodes before starting the
2200rest of the filesystem check (but after the journal playback).
2201
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002202E2fsck now validates the file descriptor passed to the -C option,
2203which saves against the completion bar getting written to an
2204unexpected location, such as the disk being checked. (Debian
2205bug/wishlist #55220)
2206
2207E2fsck will now bump the filesystem revision number from zero to one
2208if any of the compatibility bits are set.
2209
2210Fixed a bug where a badly corrupted directory on a big endian system
2211could cause e2fsck to die with a bus error. The
2212ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
2213the ext2 library now does alignment sanity checks on the rec_len field
2214of the directory entry before using it.
2215
2216The ext2 library has been enhanced to make tune2fs safe to run on
2217mounted filesystems. (Users could usually get away with using tune2fs
2218on mounted filesystems before, but with the advent of ext3 and
2219journaling, it became important to make tune2fs was *really* safe for
2220use even when the filesystem being modified is mounted.) E2label is
2221now implemented by tune2fs using an argv[0] dispatch, so that e2label
2222is also now safe for use on mounted filesystems.
2223
2224Added a new program, e2image, which creates a backup of critical ext2
2225filesystem data structures. The generated image file can be examined
2226using dumpe2fs and debugfs. In the future, e2fsck will be able to use
2227the image file to help recover very badly damaged filesystems.
2228
2229Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
2230no longer cause e2fsck to bomb out. Also treat files > 2GB as being
2231large file when deciding whether or not the filesystem has large files.
2232
2233Fixed lsattr and chattr so that they work correctly on large files.
2234(Fixes Debian bug #72690.)
2235
2236Removed limitation in get_device_size() which imposed a one terrabyte
2237filesystem limitation. (Most 2.2 kernels still have a signed int
2238problem which cause 1 TB block device limitation. Fortunately, the
2239kernel patches to fix this are much easier than fixing the 2TB
2240limitation in the kernel. :-)
2241
2242A max_mount_count of zero is now treated as if no mount count were
2243set. (Previously, no mount count was indicated by using -1, and a
2244mount count of zero caused e2fsck to always be run.)
2245
Theodore Ts'o77648562001-05-14 13:04:44 +00002246Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002247
2248Mke2fs now adds some randomness in s_max_mount_count so that multiple
2249filesystems won't be all checked at the same time under normal
2250operations.
2251
Theodore Ts'o5570a652000-08-21 01:23:39 +00002252Fixed bug in the progress bar printing code which could cause e2fsck
2253to core dump on an illegal filesystem.
2254
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002255Fixed bug in fsck which could allow more than one instance of e2fsck
2256to be printing a progress bar. (Debian bug #65267)
2257
Theodore Ts'o5570a652000-08-21 01:23:39 +00002258Fsck using a UUID or a LABEL specifier will work even if devfs is
2259compiled into the kernel and not mounted. If the pathnames in
2260/proc/partitions are incorrect, fsck will search /dev for the correct
2261device (using the new ext2fs_find_block_device library function).
2262Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002263found when they are in use. Support has also been added to support
2264additional IDE disks and the DAC 960 device names. (Debian bug #94159)
2265
2266Fixed a bug in fsck which caused it not deal properly with 16
2267byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002268
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002269Fsck's -t option has been made a lot more flexible. The semantics for
2270what happens if a comma-separated list to fsck has been regularized,
2271and it is now possible to filter what filesystems will get checked
2272based what is in the filesystem's fstab entry's option field. (Debian
2273bug #89483.)
2274
Theodore Ts'o5570a652000-08-21 01:23:39 +00002275The dumpe2fs program can now print out the group description
2276information in hex, and also prints the location of the superblock and
2277block group descriptor for those block groups that have them.
2278
2279Mke2fs now clears the ext2 superblock before it starts creating a
2280filesystem, so that the superblock magic number is only written if the
2281filesystem creation process successfully completes.
2282
2283The debugfs program's stat command now pretty-prints the blocks used
2284by an inode so that it's more compact and informative.
2285
2286The debugfs stats command now uses the same libe2p code (which is used
2287by dumpe2fs) to print the superblock header information. This is more
2288complete, and it avoids a bit of code duplication.
2289
2290Added a new debugfs command, set_super_value (ssv) which allows the
2291user to set arbitrary superblock fields.
2292
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002293Debugfs was extended to support inode numbers in hex (by prefixing
2294them with 0x), and so that modify_inode can set the inode generation
2295number. Also, there is now a new function command called logdump
2296which will dump an ext3 journal.
2297
2298Fixed a bug in debugfs so that quitting out of the pager doesn't kill
2299debugfs.
2300
2301Debugfs's dump command now stops immediately upon reporting a disk
2302read error. (Fixed a bug in ext2fs_file_read library routine which
2303caused debugfs not to stop.) (Debian bug #79163)
2304
2305On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
2306checked before /etc/mtab is used, since /proc/mounts is more likely to
2307be accurate.
2308
2309Added portability fixes for Solaris and Linux/ia64.
2310
2311Various manual pages were clarified and cleaned up. (Fixed debian
2312bugs #63442, #67446, and #87216)
2313
Theodore Ts'o5570a652000-08-21 01:23:39 +00002314
2315Programmer's notes:
2316-------------------
2317
2318The e2fsck message printer now supports %Iu and %Ig, which will print
2319out the inode's user and group owners, respectively.
2320
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002321E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
2322that no longer dependent on the system having the correct version of
2323the kernel header files.
2324
Theodore Ts'o5570a652000-08-21 01:23:39 +00002325Added a new function to libext2, ext2fs_find_block_device(), which
2326searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
2327device given its device number.
2328
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002329Added a new function to libext2, ext2fs_sync_device, which centralizes
2330all of the places which might try to use the BLKFLSBUF or FDFLUSH
2331ioctls (and usually failing to define them since the system header
2332files don't usually do this for us, and we're trying to avoid usage of
2333kernel include files now).
2334
Theodore Ts'o5570a652000-08-21 01:23:39 +00002335Added new utility programs in tests/progs: random_exercise and
2336hold_inode. They aren't built by default; they're useful for
2337exercising ext3 filesystem code.
2338
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002339Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
2340the filesystem close functions to only update the superblock, and to
2341not touch the block group descriptors. Needed by tune2fs when
2342modifying a mounted filesystem.
2343
2344Got rid of struct ext2fs_sb and replaced it with the standard struct
2345ext2_super_block from include/linux/ext2_fs.h. Note: this may break
2346source (but not binary) compatibility of some users of the ext2
2347library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00002348replace of struct ext2fs_sb with struct ext2_super_block, and include
2349the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002350
2351The ino_t type has been renamed ext2_ino_t to protect applications
2352that attempt to compile -D_FILE_OFFSET_BITS=64, since this
2353inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
2354unexpected ABI change.
2355
2356The Makefiles have been reworked so that "make check" can be run from
2357the top-level Makefile.
2358
2359Fix general gcc -Wall complaints and removed dead code.
2360
2361Remove use of NOARGS, because we assume everyone does ANSI C these
2362days.
2363
2364Added build-rpm script from sct.
2365
2366New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
2367to support e2image.
2368
2369New function ext2fs_flush_icache which must be called if the
2370application program modifies the inode table blocks without going
2371through ext2fs_write_inode() interface.
2372
2373New ext2fs_check_mount_point() function, which will return the mount
2374point of a device if mounted.
2375
2376The io_channel abstraction now has an optional interface,
2377io_channel_write_range, which allows specific byte ranges to be
2378written.
2379
2380The unix_io IO channel now supports write-through caching, so that
2381journal creation is more efficient.
2382
2383Added x86 assembly language routines to support byte swapping, to
2384reduce executable size.
2385
2386Fixed bug in the utility program subst so that it's possible to
2387replace a substitution variable with a zero-length string.
2388
2389Fixed numbering e2fsck pass1 problem numbers; an extra zero had
2390slipped into some of the problem number.

Theodore Ts'ob777e262000-07-27 01:39:23 +00002392E2fsprogs 1.19 (July 13, 2000)
2393==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00002394
2395Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00002396be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00002397
2398Add experimental support needed for the ext2 compression patches.
2399This requires compiling e2fsprogs with the --enable-compression flag
2400to the configure script.
2401
2402Added ext3 journalling support. E2fsck will run the journal (if
2403necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
2404installed as a symlink to e2fsck. Fsck has been taught about ext3,
2405and treats it the same as ext2 in terms of the progress bar logic.
2406Dumpe2fs will display the superblock journaling information if the
2407filesystem has a journal. The ext2 library will now permit opening an
2408ext3 filesystem with the recovery flag set. This is necessary for
2409on-line dump's to work correctly, but there may be issues with this
2410working well since ext3 is much less agressive about syncing blocks to
2411the filesystem, since they're safe on the journal.
2412
2413Tune2fs and e2fsck have been changed to allow the mount_count check to
2414be disabled by setting max_mount_count to -1. (This was already
2415supported by the kernel.)
2416
2417Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
2418are used for ext3 as well.
2419
2420Added internationalization support for e2fsprogs; must be enabled
2421by passing --enable-nls to configure.
2422
2423Always use the provided ext2fs header files to insulate ourselves from
2424kernel version changes. Which include files are used by e2fsprogs
2425have also been cleaned up to improve portability.
2426
2427Limit the number of times that e2fsck updates the progress bar so that
2428people who are booting using a 9600 baud console don't get swampped by
2429too many updates.
2430
2431Improved the loop detection algorithm in e2sck's pass #3 so that it is
2432much, much faster for large filesystems with a large number of
2433directories.
2434
2435The memory footprint for e2fsck is now slightly smaller than before.
2436
2437E2fsck now checks if special devices have a non-zero size, and offers
2438to clear the size field if it finds such an inode.
2439
2440E2fsck now checks if special devices have the append-only flag set,
2441and offers to clear the inode.
2442
2443E2fsck now properly handles some "should never fail" cases during a
2444bitmap copy in pass5.
2445
2446E2fsck now properly prints control characters in filenames as ^A .. ^Z.
2447
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002448E2fsck now calculates the correct location of the backup superblock in
2449the case of filesystem blocksizes > 1k.
2450
2451Fixed a bug in e2fsck's calculation of the number of inodes_per_block
2452which normally didn't cause problems under most filesystem parameters,
2453but could cause a valid superblock to be rejected in extreme cases.
2454Other checks for validating superblock values were made more
2455stringent.
2456
Theodore Ts'oab146762000-07-07 04:37:35 +00002457Added non-destructive write testing to the badblocks program, courtesy
2458of David Beattie. The badblocks also now has an option to input the
2459current set of bad blocks, so that known bad blocks are skipped to
2460speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00002461feature which causes badblocks to run until it has completed some
2462number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00002463
2464Badblocks now checks to see if the device is mounted and refuses to do
2465the tests involving writing to the device if it is mounted. Also,
2466badblocks now allows the number of blocks to be checked to be
2467defaulted to the size of the partition.
2468
2469Fixed a bug in fsck which didn't allow non-root users to be able to
2470check filesystems if there were any LABEL= or UUID= entries in
2471/etc/fstab.
2472
2473The Hurd doesn't support the filetype filesystem feature. The mke2fs
2474program now makes sure that for the Hurd, the filestype feature is
2475turned off. E2fsck will check to see if the filetype feature is
2476turned on for Hurd filesystems, and offer to turn off the feature.
2477
2478Mke2fs now has a safety check to make sure the number of blocks do not
2479exceed 32 bits even on a 64 bit platform.
2480
2481Really fixed a bug in fsck to allow "fsck -As" to run interactive
2482fsck's. (For those people who like to do interactive fsck's in the
2483/etc/rc scripts!?!)
2484
2485Debugfs has a few new features: the rdump command, which will do a
2486recursive dump of a directory and all of its contents, and the lcd
2487command which does a local chdir (much like the ftp command of the
2488same name). In addition, the debugfs program and the open_filesystem
2489command now takes three new options: -b and -s, which allows the
2490blocksize and superblock location to be specified, and the -c option
2491which is used in catastrophic situations where the block group
2492descriptors are corrupt. If the -c option is specified, debugfs will
2493skip trying to read in the block and inode bitmaps.
2494
2495Debufs's lsdel command was fixed to handle bad blocks in the inode
2496table.
2497
2498A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
24994 digit years.
2500
2501General improvements in error messages
2502
2503 - Mke2fs prints a sane error message if the partition size is zero
2504 (usually because the partition table wasn't reread by the
2505 kernel due to the partition being busy), instead of "invalid
2506 argument passed to ext2 library while initializing superblock".
2507
2508 - Fsck now prints more self-explanatory message if an invalid UUID=
2509 or LABEL= specification is passed to it.
2510
2511UUID library changed to use the LGPL.
2512
2513Fixed a bug in the UUID library where very rapid calls to the
2514time-based UUID generator could cause duplicate UUID's to be returned.
2515This was not a problem for e2fsprogs, but it could be a problem for
2516other users of the library.
2517
2518Make the UUID library more robust in the face of missing or an
2519improper /dev/urandom or /dev/random files.
2520
2521Added some random portability fixes for Solaris.
2522
2523Some minor man page updates.
2524
2525Fixed a memory leak in the ss library.
2526
2527
2528Programmer's notes:
2529-------------------
2530
2531We now try to use lseek64 and open64 from the LFS if possible.
2532
2533The 3rd parameter in e2p's print_flags is now a flags word, instead of
2534a boolean option.
2535
2536The mark and unmark bitmap functions now return the previous state of
2537the bit that was being changed, which is useful for some speed
2538optimizations.
2539
2540The following functions have been added to enhance the badblocks list
2541handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
2542ext2fs_badblocks_equal.
2543
2544The ext2 header files now have the latest journalling fields to the
2545superblock.
2546
2547The ext2fs_mkdir function in libext2fs now properly backs out of error
2548conditions robustly.
2549
2550Cleaned up makefiles:
2551 - to cleanly compile with the -j flag.
2552 - so distclean removes all generated files.
2553 - so in case of an error while installing header files, the make aborts.
2554
2555Fix test_script so that it works correctly when compiling in the
2556source directory.
2557
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002558The random UUID generation routine has been made slightly better in
2559the case where /dev/random doesn't exist. (Use of randomly-based UUID
2560is still not recommended if /dev/random doesn't exist, however; it's
2561better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00002562
2563Clean up the build process so it's more friendly in case of missing
2564directories.
2565
2566The ext2fs header file can now be #include'd into C++ programs.
2567
2568The e2p.h header file is now installed.
2569
2570Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
2571
2572
2573
Theodore Ts'o24ded091999-11-10 15:56:16 +00002574E2fsprogs 1.18 (November 10, 1999)
2575==================================
2576
2577Fix a core dumping bug in e2fsck if an imagic inode is present or
2578(more rarely) if the filesystem is badly corrupted enough that e2fsck
2579has to restart pass 1 processing. E2fsck now closes the filesystem
2580before freeing a large number of its data structures, so in the case
2581of future memory faults, at least the fixed filesystem will be fully
2582written out.
2583
2584If a filesystem doesn't support imagic inodes, and e2fsck discovers an
2585imagic inode, it will offer to clear the imagic flag.
2586
2587E2fsck will now offer to clear the immutable flag on special files
2588(device/socket/fifos) when running it in non-preen mode.
2589
2590E2fsck will now set the filetype when creating /lost+found, and when
2591connected orphaned inodes to /lost+found.
2592
2593Debugfs's ncheck and icheck commands now handles the case where there
2594are bad blocks in the inode table without bombing out.
2595
2596The badblocks list processing code has been made more efficiently for
2597appending a large number of (ordered) badblocks to the badblocks list.
2598
2599Some minor man page updates.
2600
2601Fsck now allows interactive e2fsck's when using fsck -As (not a common
2602mode, but some people like to do this in boot scripts for silly reasons).
2603
2604Programmer's notes:
2605-------------------
2606
2607The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
2608with the problem code convention.
2609
2610The badblocks list regression test program has been updated to work
2611with previously made API name changes.
2612
2613The ext2fs_free() command now uses the new badblocks API to avoid
2614using the compatibility layer.
2615
2616Added new regression test cases; the run_e2fsck test script now
2617supports the ability for a test case to run a prepratory command
2618before running e2fsck.
2619
Theodore Ts'o28e11941999-10-26 18:17:20 +00002620E2fsprogs 1.17 (October 26, 1999)
2621=================================
2622
2623Fixed nasty typo in fsck which caused parallelized fsck's to go into an
2624infinite loop.
2625
2626Fixed a bug in fsck where it used strncmp to compare a binary UUID,
2627thus potentially causing problems if a binary UUID contained a NULL
2628character.
2629
2630E2fsck now uses stricter checks for directory entries in pass 2:
2631zero-length filenames are not allowed; neither are 8 byte long
2632directory entries.
2633
2634The debugfs "dirty" command now clears the filesystem valid bit.
2635(Previously this just set the dirty-as-in-needs-writing-out-to-disk
2636bit in the in-core superblock image. The new functionality is more
2637what the user expects, and is more useful.)
2638
2639Added a debugging hook to test parallel fsck; if the environment
2640variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
2641will be checked in parallel when they normally would not be.
2642
2643Programmer's notes:
2644-------------------
2645
2646Fixed some #ifdef's for compilation under the Hurd OS.
2647
2648Fixed minor W2K compatibility problems.
2649
2650Fixed some miscellaneous GCC warnings.
2651
2652
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00002653E2fsprogs 1.16 (October 22, 1999)
2654=================================
2655
2656Fixed a race condition bug in fsck; when printing a progress bar, if
2657checking multiple filesystems in parallel, it was possible for fsck to
2658send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
2659handler, which would cause it to terminate with a signal 10.
2660
2661E2fsck now properly handles filesystems that have the
2662INCOMPAT_FILETYPE feature turned on. It can be used to convert a
2663filesystem into using or not using FILETYPE feature.
2664
2665E2fsck now properly handles filesystems that have the IMAGIC feature
2666turned on (this is used on Linux AFS servers).
2667
2668The mke2fs program now creates filesystems that have the filetype and
2669sparse_superblock features enabled by default, unless it is run on a
2670pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
2671so there is now a new flag -O which allows the user to specify with
2672which features she would like to create the filesystem; "mke2fs -O
2673none" will create a filesystsem compatible with 2.0 kernels.
2674
2675The tune2fs program now has a -O option which allows the user to set
2676and reset "safe" filesystem features. Currently, the only ones which
2677allows to be modified are the filetype and sparse_superblock features.
2678Note setting or clearing either feature will require running e2fsck on
2679the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
2680requires that there is enough free space on the filesystem for the
2681extra superblocks which will be created by e2fsck.)
2682
2683Debugfs can now set and print filesystem features in the superblock
2684using the "features" command. Dumpe2fs will print out the complete
2685set of features when listing the superblock.
2686
2687Dumpe2fs has new options -f (force) and -h (header-only).
2688
2689Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
2690message to come up. This could happen when decrementing or
2691incrementing a link count could result in an overflow.
2692
2693Fixed a bug in e2fsck where the block count on the lost+found
2694directory would not be properly incremented when the directory was
2695expanded to the point where an indirect block needed to be allocated.
2696
2697E2fsck now makes some additional sanity checks on the superblock to
2698avoid crashing or giving a memory allocation error if some of the
2699values in the superblock are unresonable (but the superblock otherwise
2700looks valid).
2701
2702Fixed a bug in e2fsck where a very badly corrupted filesystem might
2703require two passes to completely fix the filesystem. This happened if
2704an inode claimed blocks that was part of the filesystem metadata
2705(typically, when garbage was written into an inode table or indirect
2706block, since this kind of filesystem corruption normally doesn't
2707happen otherwise).
2708
2709On the Alpha, glibc declares st_flags although it isn't actually used;
2710the configure script was improved to detect this case so that
2711e2fsprogs can avoid using the non-functional stat field.
2712
2713The manual pages were updated to use a more consistent formatting
2714style consistent with standard Unix man pages. Mke2fs's man page
2715added documentation for a few previously undocumented options.
2716
2717Fixed minor display bugs in tune2fs and mke2fs.
2718
2719Programmer's notes:
2720-------------------
2721
2722Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
2723
2724Added features to parse and print feature strings into the e2p library.
2725(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
2726
2727ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
2728whose directory entries contain proper filetype information if the
2729filesystem supports it.
2730
2731ext2fs_link() now uses the low 3 bits of its flags parameter to pass
2732the directory entry filetype information. This is used to set the
2733directory entry filetype information if the filesystem supports it.
2734
2735Fixed a bug in ext2fs_expand_dir() where the block count in a
2736directory's inode would not be properly incremented when the directory
2737was expanded to the point where an indirect block needed to be
2738allocated.
2739
2740
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002741E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002742==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002743
2744Add configuration checks so that e2fsprogs will compile cleanly on
2745Linux 2.3 kernels that have renamed i_version to i_generation.
2746
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002747E2fsck now prints a progress/completion bar (and not just a simple
2748spinner) if the -C0 option is requested or if it receives a SIGUSR1
2749signal. Fsck will automatically manage the (potentially muliple)
2750e2fsck processes to print completion bars if it is given a -C option,
2751with the right thing happening if multiple filesystems are being
2752checked in parallel.
2753
2754Mke2fs now has better automatic hueristics to determine the filesystem
2755parameters to be used for a particular filesystem. Added a new option
2756-T which allows the user to specify how the filesystem is to be used,
2757which helps mke2fs do a better job selecting the filesystem parameters.
2758
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002759Mke2fs now creates revision 1 filesystems by default, and with the
2760sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00002761not understood by Linux 2.0 kernels, so they will only allow read-only
2762mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002763
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002764Fix bug where if /dev/null couldn't be opened (should never happen),
2765e2fsck would hang in a tight loop.
2766
2767Make e2fsck handle the case where /lost+found isn't a directory.
2768
2769E2fsck now uses mallinfo if it exists to get accurate statistics about
2770its memory usage.
2771
2772Fix bug in e2fsck where it wouldn't check to see if a disconnected
2773inode had any problems before connecting it to /lost+found.
2774
2775Add check to e2fsck so it makes sure that total number of inodes in
2776the filesystem is a sane number.
2777
2778Fix fencepost error when clearing an the end of the block bitmap which
2779caused the last block in the bitmap not to get cleared.
2780
2781Cleaned up a number of messages in e2fsck:
2782 * The message "Group's #'s copy of the group descriptor..."
2783 was fixed so that the correct number would be displayed.
2784 * Added missing space in the "disk write-protected" error messsage
2785 * Cleaned up the error message printed when a non-interactive
2786 e2fsck needs to abort a check because the filesystem
2787 appears to be mounted.
2788
2789Added a new command-line utility, uuidgen, which will create and print
2790a UUID.
2791
2792Make debugfs's icheck command more robust by checking to make sure an
2793inode has valid blocks before interarting over the inode's blocks.
2794
2795UUID generation now uses a random-based scheme whenever possible to
2796prevent potential privacy problems.
2797
2798Man pages for all of the UUID functions in the lirbary were added.
2799
2800Fixed bug in fsck so it won't coredump if a filesystem not in
2801/etc/fstab is given to it.
2802
2803Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
2804that most of the other mount utilities understands.
2805
2806Mke2fs will make a filesystem even if it appears mounted if the force
2807option is given.
2808
2809Dumpe2fs has new command-line options which allow a filesystem expert
2810to specify the superblock and blocksize when opening a filesystem.
2811This is mainly useful when examining the remains of a toasted
2812filesystem.
2813
2814The badblocks program has been updated to display correctly on disks
2815with large block numbers.
2816
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002817The badblocks program no longer gives spurious errors when errors
2818occur on non-block boundaries, which is common if the blocksize is
2819larger than 1k.
2820
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002821Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
2822MKE2FS_SYNC environment variable is set. This is to work around a VM
2823bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002824to trigger it even using a 2.2 kernel, but hopefully it will not be
2825needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002826
2827Fixed miscellaneous documentation and man pages.
2828
2829Programmer's notes:
2830-------------------
2831
2832Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
2833in e2fsck's pass1.c really should have been static.
2834
2835The return value of the uuid_compare() function was changed to make it
2836match with the convetions used by strcmp, memcmp, and Paul Leach's
2837UUID sample document.
2838
2839The "make depend" process has now been made more automated; it now
2840automatically word-wraps the dependencies, and only replaces source
2841Makefile.in if there has been a change in the dependencies. Also, a
2842top-level "make depend" now recurses through all the subdirectories
2843automatically.
2844
2845The Makefile in .../util has been changed so that subst is built using
2846the native C compiler during a cross-compilation, since the subst
2847program is only used during the build process. Also add an explicit
2848rule to build util/subst by cd'ing to the correct directory and
2849running Makefile.
2850
2851The man directories are defined in terms mandir, so that the configure
2852script can override the location of the manual pages.
2853
2854The config files have been updated to recognize new machine types for
2855both the i386 and alpha families.
2856
2857Fsck has been modified so that it will accurately create an
2858fsck_instance even when the noexecute flag is set. This allows for
2859accurate debugging of the fsck pass structure. Also, when the verbose
2860flag is given twice, fsck will print debugging information about when
2861fsck is waiting for jobs to finish.

Theodore Ts'o14790ed1999-01-12 23:32:52 +00002864E2fsprogs 1.14 (January 9, 1999)
2865================================
2866
2867Fix the fstab parsing code so that it can handle blank lines and
2868comment characters. Also, missing pass numbers need to be treated as
2869zero.
2870
2871Fixed a bug in e2fsck where under some circumstances (when e2fsck
2872needs to restart processing after fixing an egregious inconsistency)
2873it would try to access already freed memory.
2874
2875E2fsck now prints non-printable characters in directory entries and
2876pathnames using '^' and 'M-' notation.
2877
2878Fixed chattr so that it will ignore symbolic links when doing
2879recursive descent traversals. For both chattr and lsattr, no longer
2880print the version string unless the -V option is given.
2881
2882Allow the system administrator to directly specify the number of
2883inodes desired in the filesystem, for some special cases where this is
2884necessary.
2885
2886Fix portability problems so that e2fsprogs can be compiled under Linux
28871.2 systems and Solaris systems.
2888
2889Update the config.guess file with a more recent version that will
2890identify newer Linux platforms.
2891
2892Programmer's notes
2893------------------
2894
2895Ext2fs_read_inode and ext2fs_write_inode will now return an error if
2896an inode number of zero is passed to them.
2897
Theodore Ts'o556ad131998-12-19 08:10:58 +00002898E2fsprogs 1.13 (December 15, 1998)
2899==================================
2900
2901Fixed a bug in debugfs where an error messages weren't getting printed
2902when the ext2 library routines to read inodes returned errors in the
2903stat, cmri and rm commands.
2904
2905Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
2906provided, it won't create an inode table smaller than the minimum
2907number of inodes required for a proper ext2 filesystem.
2908
2909Fsck now parses the /etc/fstab file directly (instead of using
2910getmntent()), so that it can distinguish between a missing pass number
2911field and pass number field of zero. This caused problems for
2912diskless workstations where all of the filesystems in /etc/fstab have
2913an explicit pass number of zero, and fsck could not distinguish this
2914from a /etc/fstab file with missing pass numbers.
2915
2916E2fsck will create a /lost+found directory if there isn't one in the
2917filesystem, since it's safer to create the lost+found directory before
2918it's needed.
2919
2920Fixed e2fsck so that it would detect bogus immutable inodes which
2921happen to be sockets and FIFO files, and offer to clear them.
2922
2923If a filesystem has multiple reasons why it needs to be checked, and
2924one of the reasons is that it is uncleanly mounted, e2fsck will print
2925that as the reason why the filesystem is being checked.
2926
2927Cleaned up the output routines of mke2fs so that it doesn't overflow
2928an 80 column display when formating really big filesystems.
2929
2930Added a sanity check to e2fsck to make sure that file descriptors 0,
29311, 2 are open before opening the hard disk. This avoids a problem
2932where a broken program might exec e2fsck with those file descriptors
2933closed, which would cause disastrous results if the kernel returns a
2934file descriptor for the block device which is also used by FILE *
2935stdout.
2936
2937Fixed up the e2fsck progress reporting functions so that the values
2938reliably reach 100% at the completion of all of the e2fsck passes.
2939
2940Fixed minor documentation bugs in man pages and usage messages.
2941
2942Programmer's notes:
2943-------------------
2944
2945Fixed a number of lint warnings in the ext2fs library and potential
2946portability problems from other OS's header files that might define
2947CPP macros for names like "max" and "min".
2948
2949ext2fs_badblocks_list_add() has been made more efficient when it needs
2950to grow the bad blocks list.
2951
2952Fixed a bug in e2fsck which caused it to dereference a freed pointer
2953just before exiting.
2954
2955Fixed the substition process for generating the mk_cmds and compile_et
2956scripts so that they will work outside of the build tree.
2957
2958Add sanity check to e2fsck so that if an internal routine
2959(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
2960and causing a core dump. This should never happen, but...
2961
Theodore Ts'oa5696711998-07-09 05:38:07 +00002962E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00002963==================================
2964
2965E2fsprogs now works with glibc (at least with the version shipped wtih
2966RedHat 5.0). The ext2fs_llseek() function should now work even with
2967i386 ELF shared libraries and if llseek() is not present. We also
2968explicitly do a configure test to see if (a) llseek is in libc, and
2969(b) if llseek is declared in the system header files. (See standard
2970complaints about libc developers don't understand the concept of
2971compatibility with previous versions of libc.)
2972
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002973The ext2fs library now writes out the block group number in each of
2974the superblock copies. This makes it easier to automatically
2975determine the starting block group of the filesystem when the block
2976group information is trashed.
2977
2978Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00002979which means that e2fsprogs will ignore the high 8 bits of the
2980directory entry's name_len field, so that it can be used for other
2981purposes.
2982
2983Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
2984E2fsprogs will now support filesystems with 64-bit sized files.
2985
2986Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
2987
Theodore Ts'o21d53851998-02-21 03:14:50 +00002988Added new program "e2label", contributed by Andries Brouwer. E2label
2989provides an easy-to-use interface to modify the filesystem label.
2990
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002991Fixed bug so that lsattr -v works instead of producing a core dump.
2992
Theodore Ts'o21d53851998-02-21 03:14:50 +00002993Fixed a minor bug in mke2fs so that all groups with bad superblock
2994backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002995
2996Mke2fs will check the size of the device, and if the user specifies a
2997filesystem size larger than the apparent size of the device it will
2998print a warning message and ask if the user wants to proceed.
2999
Theodore Ts'oc9833a61998-07-05 19:37:53 +00003000E2fsck has a new option -C, which sends completion information to the
3001specified file descriptor. For the most part, this is intended for
3002programs to use, although -C 0 will print a spinning character to the
3003stdout device, which may be useful for users who want to see something
3004happening while e2fsck goes about its business.
3005
Theodore Ts'o21d53851998-02-21 03:14:50 +00003006Fixed a bug in e2fsck which could cause a core dump when it needs to
3007expand the /lost+found directory, and sometimes the bitmaps haven't
3008been merged in. Also fixed a related bug where ext2fs_write_dir_block
3009was used to write out a non-directory block. (Which would be bad on a
3010non-Intel platform with byte swapping going on.)
3011
3012Fixed bug in e2fsck where it would print a "programming error" message
3013instead of correctly identifying where a bad block was in used when
3014the bad block was in a non-primary superblock or block group
3015descriptor. Also fixed a related bug when sparse superblocks are in
3016use and there is a bad block where a superblock or block group
3017descriptor would have been in a group that doesn't include a
3018superblock.
3019
3020Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
3021the block group descriptor table is corrupt, it was possible to try to
3022allocate a huge array, fail, and then abort e2fsck.
3023ext2fs_get_num_dirs() now sanity checks the block group descriptor,
3024and subsitutes reasonable values if the descriptors are obviously bogus.
3025
3026If e2fsck finds a device file which has the immutable flag set and the
3027i_blocks beyond the normal device number are non-zero, e2fsck will
3028offer to remove it, since it's probably caused by garbage in the inode
3029table.
3030
3031When opening a filesystem, e2fsck specially checks for the EROFS error
3032code, and prints a specific error message to the user which is more
3033user friendly.
3034
3035If the filesystem revision is too high, change the e2fsck to print
3036that this is either because e2fsck is out of date, or because the
3037superblock is corrupt.
3038
3039E2fsck now checks for directories that have duplicate '.' and '..'
3040entries, and fixes this corruption.
3041
3042E2fsck no longer forces a sync of the filesystem (with attendant sleep
3043calls) at all times. The ext2fs_flush() function now performs a sync
3044only if it needed to write data blocks to disk.
3045
3046Fixed a minor bug in e2fsck's pass1b's file cloning function, where
3047certain errors would not be properly reported.
3048
3049Updated and expanded a few points in the man pages which users
3050complained wheren't explicit enough.
3051
3052Added special case byte-swapping code if compiling on the PowerPC, to
3053accomodate the strange big-endian variant of the ext2 filesystem that
3054was previously used on the PowerPC port.
3055
3056
3057Programmer's notes:
3058-------------------
3059
3060Removed C++ keywords from the ext2fs libraries so that it could be
3061compiled with C++.
3062
3063E2fsck's internal organization has now been massively reorganized so
3064that pass*.c don't have any printf statements. Instead, all problems
3065are reported through the fix_problem() abstraction interface. E2fsck
3066has also been revamped so that it can be called as a library from a
3067application.
3068
3069Added new fileio primitives in libext2fs for reading and writing
3070files on an unmounted ext2 filesystem. This interface is now used by
3071debugfs.
3072
3073Added a new libext2fs function for mapping logical block numbers of
3074a file to a physical block number.
3075
3076Added a new libext2fs function, ext2fs_alloc_block(), which allocates
3077a block, zeros it, and updates the filesystem accounting records
3078appropriately.
3079
3080Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
3081sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
3082
3083The libext2fs functions now use a set of memory allocation wrapper
3084functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
3085instead of malloc, free, and resize. This makes it easier for us to
3086be ported to strange environments where malloc, et. al. aren't
3087necessarily available.
3088
3089Change the libext2fs fucntion to return ext2-specific error codes
3090(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
3091and depending on the existence of system error codes (such as EEXIST
3092and ENOENT).
3093
3094Renamed io.h to ext2_io.h to avoid collision with other OS's header
3095files.
3096
3097Add protection against ext2_io.h and ext2fs.h being included multiple
3098times.
3099
3100The types used for memory lengths, etc. have been made more portable.
3101In generla, the code has been made 16-bit safe. Added Mark
3102Habersack's contributed DOS disk i/o routines.
3103
3104Miscellaneous portability fixes, including not depending on char's
3105being signed.
3106
3107The io_channel structure has a new element, app_data, which is
3108initialized by the ext2fs routines to contain a copy of the filesystem
3109handle.
3110
3111ext2fs_check_directory()'s callback function may now return the error
3112EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
3113really do the checking, despite the presence of the callback function.
3114
3115
Theodore Ts'obc210071997-06-17 05:41:36 +00003116E2fsprosg 1.11 (June 17, 1997)
3117==============================
3118
3119Fixed e2fsck to detect (previously ignored) conflicts between the
3120superblock or block group descriptors and block bitmaps, inode
3121bitmaps, and inode tables.
3122
3123Fixed bug in e2fsck so that when the message printed out when a block
3124or inode bitmap conflicts with other data, it has the correct group
3125number.
3126
3127Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
3128to badblocks. This meant that not all of the filesystem was being
3129tested for bad blocks!
3130
3131Fixed an array boundary overrun case which cropped up in
3132ext2fs_badblocks_list_test when a user tried running "mke2fs -c
3133-b 4096".
3134
3135Adjusted the number of columns printed by mke2fs when displaying the
3136superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00003137really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00003138
3139Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
3140dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
3141fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
3142
3143Programmer's notes:
3144-------------------
3145
3146Fixed install rule in lib/ss so that ss_err.h is actually getting
3147installed.
3148
3149Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
3150bassed back to the caller.
3151
3152Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
3153setting the current inode number (which meant this function wasn't
3154working at all).
3155
3156Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
3157blocks in the bitmap when increasing the size of the bitmap.
3158
3159Changed the initial number of blocks allocated by ext2fs_init_dblist()
3160to be more realistic.
3161
3162Added a new function ext2fs_allocate_group_table, which sets up the
3163group descriptor information (and allocates inode and block bitmaps,
3164and inode tables for a particular group). The function was created by
3165factoring out code form ext2fs_allocate_tables().
3166
3167Added a new function ext2fs_move_blocks which takes a bitmap of the
3168blocks to be moved, and moves them to another location on the
3169boardboard.
3170
3171Make the unix_io channel's io_channel_flush implementation calls sync()
3172to to flush the kernel buffers to disk.
3173
3174Added a new function ext2fs_dblist_count returns the number of
3175directory blocks in dblist.
3176
3177
Theodore Ts'oae851481997-04-29 18:13:24 +00003178E2fsprogs 1.10 (April 24, 1997)
3179===============================
3180
3181Mke2fs once again defaults to creating revision #0 filesystems, since
3182people were complaining about breaking compatibility with 1.2 kernels.
3183Warning messages were added to the mke2fs and tune2fs man pages that
3184the sparse superblock option isn't supported by most kernels yet (1.2
3185and 2.0 both don't support parse superblocks.)
3186
3187Added new flag to mke2fs, -R <raid options>, which allows the user to
3188tell mke2fs about the RAID configuration of the filesystem. Currently
3189the only supported raid option is "stride" which specifies the width
3190of the RAID stripe.
3191
3192Fixed bug in e2fsck where pass1b would bomb out if there were any
3193blocks marked bad in the inode table.
3194
3195Fixed rare bug in mke2fs where if the user had a very unlucky number
3196of blocks in a filesystem (probability less than .002) the resulting
3197filesystem would be corrupt in the last block group.
3198
3199Fixed bug where if e2fsck tried to allocate a block to fix a
3200filesystem corruption problem and the filesystem had no free blocks,
3201ext2fs_new_block() would loop forever.
3202
3203The configure script now checks explicitly to see if "-static" works,
3204since that can't be assumed to be true --- RedHat doesn't install
3205libc-static by default.
3206
3207Fixed bug in libext2's block iterator functions where under some
3208cirmcustances, file with holes would cause the bcount parameter to the
3209callback function to be incorrect. This bug didn't affect any of
3210e2fsprogs programs, but it was discovered by Paul Mackerras, the
3211author of the PPC boot loader.
3212
3213Removed use of static variables to store the inode cache in libext2fs.
3214This caused problems if more than one filesystem was accessed via
3215libext2fs (static variables in libraries are generally a bad idea).
3216Again, this didn't affect e2fsprogs programs, but it was discovered by
3217Paul Mackerras.
3218
3219Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
3220will compile cleanly with 1.2.13 kernels (even with a.out shared
3221libraries!)
3222
3223Programmer's notes:
3224-------------------
3225
3226Added new functions to duplicate an ext2 filesystem handle, and its
3227associated substructure. New functions: ext2fs_dup_handle(),
3228ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
3229Other structures, such as the io_channel and the inode_cache, now have
3230a ref count so that they only get freed when they are no longer used
3231by any filesystem handle. (These functions were added as part of the
3232development effort for an ext2 resizer).
3233
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00003234E2fsprogs 1.09 (April 14, 1997)
3235===============================
3236
3237Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
3238accidentally introduced in the 1.08 release. The overhead calculation
3239was accidentally removed, which caused ext2fs_initialize() to not
3240notice when the filesystem size needed to be adjusted down because
3241there wasn't enough space in the last block group.
3242
3243Fixed bug in version parsing library routine; it was always parsing
3244the library version string, instead of using the passed-in string.
3245
3246Clarified chattr man page.
3247
Theodore Ts'o24757fa1997-04-29 17:39:27 +00003248E2fsprogs 1.08 (April 10, 1997)
3249===============================
3250
3251E2fsck 1.07 was very slow when checking very large filesystems with a
3252lot of files that had hard links (i.e., news spools). This was fixed
3253by seriously revamping the icount abstraction. Added a formal test
3254suite for the icount abstraction.
3255
3256Debugfs now has a "-l" option to the "ls" command, which lists the
3257inode number, permissions, owner, group, size, and name of the files
3258in the directory.
3259
3260Fix a bug in e2fsck where when a directory had its blocks moved to
3261another location during the pass 1b processing, the directory block
3262list wasn't updated, so pass 2 wouldn't check (and correct) the
3263correct directory block.
3264
3265E2fsck will now treat inodes which contain blocks which are claimed by
3266the filesystem metadata by treating them as multiply claimed blocks.
3267This way, the data in those blocks can be copied to a new block during
3268the pass 1b--1d processing.
3269
3270E2fsck will attempt to determine the correct superblock number and
3271display it in the diagnostic and warning messages if possible.
3272
3273Add support for a new (incompatible) feature, "sparse_super". This
3274feature reduces the number of blocks which contain copies of backup
3275superblocks and block group descriptors. (It is only an incompatible
3276feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
3277support a new -s option; e2fsck will recognize filesystems built with
3278this feature turned on.
3279
3280E2fsck now checks the library to make sure is the correct version,
3281using new library functions. (This helps to diagnose incorrectly
3282installed e2fsprogs distributions.)
3283
3284Dumpe2fs now prints more information; its now prints the the
3285filesystem revision number, the filesystem sparse_super feature (if
3286present), the block ranges for each block group, and the offset from
3287the beginning of the block group.
3288
3289Mke2fs now distributes the inode and block bitmap blok so that the
3290won't be concentrated in one or two disks in RAID/striping setups.
3291Also, if the user chooses a 2k or 4k block group, mke2fs will try to
3292choose the largest blocks per group that be chosen. (For 2k blocks,
3293you can have up to 16384 blocks/group; for 4k blocks, you can have up
3294to 32768 blocks/group.) Previously mke2fs would not allow
3295specification of more than 8192 blocks per group, even if you were
3296using a 2k or 4k block group.
3297
3298Programmer's notes:
3299-------------------
3300
3301Added a new function ext2fs_create_icount2() which takes a "hint"
3302argument. This hint argument presets the icount array with the list
3303of inodes which actually need to be in the icount array. This really
3304helps to speed up e2fsck.
3305
3306Added a new function ext2fs_icount_validate() which checks the rep
3307invariant for the icount structure. This is used mostly for testing.
3308
3309The error mesasage given when a bad inode number is passed to
3310test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
3311EXT2FS_UNMARK_ERROR).
3312
3313Added a new function ext2fs_set_dir_block which sets the block of a
3314dblist entry, given the directory inode and blockcnt.
3315
3316Added a new function ext2fs_get_library_version() which returns the
3317current library version, and ext2fs_parse_version_string() which
3318returns a version number based on a e2fsprogs version string.
3319
3320The icount functions will return EINVAL if the passed in inode number
3321is out of bounds.

Theodore Ts'o21c84b71997-04-29 16:15:03 +00003323E2fsprogs 1.07 (March 9, 1997)
3324==============================
3325
3326E2fsck is now uses much less memory when checking really large
3327filesystems (or rather, filesystems with a large number of inodes).
3328Previously a filesystem with 1 million inodes required 4 megabytes of
3329memory to store inode count statistics; that storage requirement has
3330now been reduced to roughly half a megabyte.
3331
3332E2fsck can now properly deal with bad blocks appearing inside the
3333inode table. Instead of trying to relocate the inode table (which
3334often failed because there wasn't enough space), the inodes in the bad
3335block are marked as in use.
3336
3337E2fsck will automatically try to use the backup superblocks if the
3338primary superblocks have a bad magic number or have missing meta-data
3339blocks (or meta-data blocks which are out of range).
3340
3341E2fsck's pass 3 has been made more efficient; most noticeable on
3342filesystems with a very large number of directories.
3343
3344Completely revamped e2fsck's system of printing problem reports. It
3345is now table driven, to make them more easily customizeable and
3346extendable. Error messages which can be printed out during preen mode
3347are now one line long.
3348
3349Fixed e2fsck's filesystem swapping code so that it won't try to swap
3350fast symbolic links or deleted files.
3351
3352Fixed e2fsck core dumping when fixing a filesystem which has no
3353directories (not even a root directory).
3354
3355Added a check to e2fsck to make sure that the length of every
3356directory entry is a multiple of 4 (since the kernel complains if it
3357isn't).
3358
3359Added a check to e2fsck to make sure that a directory entry isn't a
3360link to the root directory, since that isn't allowed.
3361
3362Added a check to e2fsk to now make sure the '.' and '..' directory
3363entries are null terminated, since the 2.0 kernel requires it.
3364
3365Added check to write_bitmaps() to make sure the superblock doesn't get
3366trashed if the inode or block bitmap is marked as being block zero.
3367
3368Added checking of the new feature set fields in the superblock, to
3369avoid dealing with new filesystem features that this package wasn't
3370set up to handle.
3371
3372Fixed a fencepost error in ext2fs_new_block() which would occasionally
3373try to allocate a block beyond the end of a filesystem.
3374
3375When the UUID library picks a random IEEE 802 address (because it
3376can't find one from a network card), it sets the multicast bit, to
3377avoid conflicting with a legitimate IEEE 802 address.
3378
3379Mke2fs now sets the root directory's owner to be the real uid of the
3380user running mke2fs. If the real uid is non-zero, it also sets
3381the group ownership of the root directory to be the real group-id of
3382the user running mke2fs.
3383
3384Mke2fs now has more intelligent error checking when it is given a
3385non-existent device.
3386
3387When badblocks is given the -vv option, it now updates the block that
3388it is currently testing on every block.
3389
3390Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
3391currently correctly if PATH wasn't already set.
3392
3393Shared libraries now built with dependencies. This allows the shared
3394library files to be used with dlopen(); it also makes the transition
3395to libc 6 easier, since ld.so can tell which libc a particular shared
3396library expects to use.
3397
3398Programmer's notes:
3399-------------------
3400
3401Added new abstraction (defined in dblist.c) for maintaining a list of
3402blocks which belongs to directories. This is used in e2fsck and other
3403programs which need to iterate over all directories.
3404
3405Added new functions which test to see if a contiguous range of blocks
3406(or inodes) are available. (ext2fs_*_bitmap_range).
3407
3408Added new function (ext2_inode_has_valid_blocks) which returns true if
3409an inode has valid blocks. (moved from e2fsck code).
3410
3411Added new function (ext2fs_allocate_tables) which allocates the
3412meta-data blocks as part of initializing a filesystem. (moved from
3413mke2fs code).
3414
3415Added a new I/O manager for testing purposes. It will either allow a
3416program to intercept I/O requests, or print debugging messages to
3417trace the activity of a program using the I/O manager.
3418
3419The badblocks_list functions now store the bad blocks in a sorted
3420order, and use a binary search to speed up badblocks_list_test.
3421
3422The inode scan function ext2fs_get_next_inode() may now return a soft
3423error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
3424those cases where part of an inode table is missing or there is a bad
3425block in the inode table.
3426
3427Added a new function (ext2fs_block_iterate2) which adds new arguments to
3428the callback function to return a pointer (block and offset) to the
3429reference of the block.
3430
3431Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
3432application to jump to a particular block group while doing an inode
3433scan.
3434
3435The badblocks list functions were renamed from badblocks_* to
3436ext2fs_badblocks_*. Backwards compatibility functions are available
3437for now, but programs should be modified to use the new interface.
3438
3439Some of the library functions were reorganized into separate files to
3440reduce the size of some programs which statically link against the
3441ext2 library.
3442
3443Put in some miscellaneous fixes for the Alpha platform.
3444

3446E2fsprogs 1.06 (October 7, 1996)
3447================================
3448
3449Fixed serious bug in e2fsck: if the block descriptors are bad, don't
3450smash the backup copies in ext2fs_close(). (The problem was that when
3451e2fsck -p discovered the problem, while it was closing the filesystem
3452and exiting, it was also blowing away the backup superblocks on the
3453disk, which was less than friendly.) We now make it the case that we
3454only write out the backup superblock and the back block descriptors if
3455the filesystem is completely free from problems.
3456
3457Fixed a bug in block_interate in the lib/ext2fs library which caused
3458e2fsck to fail on GNU Hurd-created filesystems.
3459
3460Add support for Linux/FT's bootloader, which actually uses
3461EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
3462to clear the inode.
3463
3464Add support for the "A" (no atime update) attribute. (Note: this
3465attribute is not yet in production kernels.)
3466
3467The test suite is not automatically run when doing a "make all" from
3468the top level directory. Users should manually run "make check" if
3469they wish to run the test suite.
3470
3471Upon a preenhalt(), make the printed message more explicit that
3472running e2fsck "MANAULLY" means without the -p or -a options.
3473
3474In e2fsck, if a disconnected inode is zero-length, offer to clear it
3475instead of offering to connect it to lost+found.
3476
3477In e2fsck, if a filesystem was just unmounted uncleanly, and needs
3478e2fsck to be run over it, change e2fsck to explicitly display this
3479fact.
3480
3481For dumpe2fs and e2fsck, cause the -V option to print out which
3482version of the ext2fs library is actually getting used. (This will
3483help detect mismatches of using a 1.06 utility with a 1.05 library,
3484etc.)
3485
3486Programmers' notes:
3487-------------------
3488
3489EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
3490the naming convention.
3491
3492In ext2fs_initialize(), make sure the description for the inode bitmap
3493is correctly initialize.
3494
3495Fixed minor type typo in ext2fs_allocate_generic_bitmap();
3496
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00003497E2fsprogs 1.05 (September 7, 1996)
3498==================================
3499
3500Add support for new fields in the ext2 superblock --- volume name,
3501volume UUID, and last mounted field. Dumpe2fs displays these fields,
3502tune2fs and mke2fs allows you to set them. E2fsck will automatically
3503generate a UUID for those volumes that don't have them.
3504
3505Put in support for e2fsck to recognize HURD specific ext2 features ---
3506most notably, the translator block. The e2fsprogs tools will now use
3507the creator_os field in the superblock to correctly handle different
3508OS-specific variants of the ext2 filesystem.
3509
3510E2fsck now fixes inodes which have a the deletion time set, but which
3511have a non-zero i_link_count field by offering to clear the deletion
3512time. Previously e2fsck assumed that the inode was deleted (per 0.3c
3513ext2 kernel behavior) and offered to unlink the file.
3514
3515If e2fsck sets the clean bit, but nothing else, set the exit code
3516FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
3517set the filesystem valid bit when it was previously cleared. :-) This
3518was needed to make the HURD fsck driver happy.
3519
3520If the user refuses to attach an unattached inode, e2fsck will no
3521longer set the inode's link count. Otherwise, the inode would end up
3522getting marked as unused, which might cause loss of data later.
3523
3524Make the message issued by e2fsck when the superblock is corrupt less
3525confusing for users. It now mentions that another reason for the
3526"corrupt superblock" message might be that the partition might not be
3527an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
3528
3529Make the libext2 library more robuest so that e2fsck won't coredump on
3530an illegal superblock where the blocksize is zero. (f_crashdisk is
3531the test case).
3532
3533By default, create filesystems where the default checkinterval is 6
3534months (180 days). Linux servers can be robust enough that 20 reboots
3535can be a long, long time.
3536
3537Added configure flag --enable-old-bitops, which forces the bitops to
3538use the old (native) bitmask operations. By default on the sparc
3539platform, the standard ext2 bit ordering is now used.
3540
3541Added a new feature to e2fsck to byte-swap filesystems; this can be
3542used to convert old m68k filesystems to use the standard byte-order
3543storage for the superblock, inodes, and directory blocks. This
3544function is invoked by using the '-s' option to e2fsck.
3545
3546Debugfs's "dump" command has been enhanced so that it writes out the
3547exact size of the file so that the nulls at the end of the file are
3548eliminated. The command also accept a new "-p" option which will
3549attempt preserve to preserve the ownernship, permissions, and
3550file modification/access times.
3551
3552Debugfs has two new options, -f and -R. The -R option allows the user
3553to execute a single debugfs command from the command line. The -f
3554option allows the user to specify a "command file" containing debugfs
3555commands which will get executed.
3556
3557Dumpe2fs now pretty prints the check interval, instead of just
3558printing the check interval as a number of seconds.
3559
3560Fix bugs in debugfs: the params command when no filesystem is opened
3561no longer causes a core dump. It is now possible to unlink a file
3562when a pathame containing a '/' is specified.
3563
3564Tune2fs has a new -C option which sets the number of times the
3565filesystem has been mounted.
3566
3567Fix the chattr '-v' option so that it actually works. Chattr was
3568being buggy about the -v option parsing.
3569
3570Programmers' notes:
3571-------------------
3572
3573The directory lib/uuid contains a set of library routines to generate
3574DCE compatible UUIDs.
3575
3576Extended ext2fs_namei() to handle symbolic links. Added new function
3577ext2fs_nami_follow() which will follow last symbolic link in the case
3578where the pathname points to a sym link.
3579
3580The ext2fs_block_iterate function will now return the HURD translator
3581block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
3582iterator to return data blocks only. The ext2fs.h file now defines
3583constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
3584BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
3585count field of the iterator callback function.
3586
3587The test script driver now takes an optional second argument, which is
3588the test case to be run. This allows you to run a test case without
3589needing to run the entire test suite.
3590
3591On Linux ELF systems, install the .so files in the correct places
3592(/usr/lib). The .so files must be stored in the same directory as the
3593.a files.
3594
3595Fixed miscellaneous HURD compilation issues with header file being
3596included in the right order.
3597
3598Fixed debugfs so that it resets optind to zero, not one, since setting
3599optind to zero is more correct.
3600
3601
Theodore Ts'oa4d09611997-04-29 14:28:00 +00003602E2fsprogs 1.04 (May 16, 1996)
3603=============================
3604
3605First "official" (1.03 was a limited release only) to support building
3606e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
3607kernels).
3608
3609This package includes a RPM specs file, that it can be built using the
3610RedHat Package Manager.
3611
3612E2fsck now prints a hint that if there are lots of incorrectly located
3613inode bitmaps, block bitmaps, and inode table blocks, the user might
3614want to try using e2fsck -b 8193 first, to see if that fares any
3615better.
3616
3617For ext2 filesystem written with the hurd, debugfs will now print out
3618the translator field when printing an inode structure.
3619
3620Lots of miscellaneous linking/installation cleanups:
3621
3622 Libraries are now linked using a relative pathname, instead of
3623 relying on -L working correct. It doesn't, in many cases, including
3624 current versions of GNU ld. This guarantees that the build tree is
3625 linking with the right libraries, instead of the ones installed in
3626 /usr/lib.
3627
3628 Header files, man pages, and the et/ss shell scripts are now
3629 generated using a custom substitution script, instead of relying on
3630 the configure script. This prevents needless recompilation of
3631 files; in addition, the custom substitution script is much faster.
3632
3633 e2fsck may now be linked dynamically, by using the
3634 --enable-dynamic-e2fsck flag to configure. This is not recommended,
3635 since it increases e2fsck's dependence on other files, but some
3636 people need to save disk space, and other critical programs on their
3637 systems were being linked dynamically anyway.
3638
3639 Programs such as fsck which didn't need to be linked against
3640 libext2fs (or mke2fs which didn't need to be linked against libe2p)
3641 only link against libraries they actually need. Otherwise, those
3642 programs would require the presense of libraries that otherwise
3643 could be removed from a rescuse diskette.
3644
3645 The ss include files are now installed correctly so they can
3646 actually be used by another package.
3647
3648 If the profiling libraries are built, they are now installed on a
3649 "make install-libs".
3650

Theodore Ts'o7f88b041997-04-26 14:48:50 +00003652E2fsprogs 1.03 (March 27, 1996)
3653===============================
3654
3655Change the m68k bit numbering for bitmasks to match the bit numbering
3656used by all other ext2 implementations. (This change was requested by
3657the m68k kernel development team.)
3658
3659Support (in-development) filesystem format revision which supports
3660(among other things) dynamically sized inodes.
3661
3662Fixed a bug in the ext2 library so that an intelligent error is
3663returned if mke2fs is run with a ridiculously small number of blocks
3664for a partition.
3665
3666Fixed a bug in the ext2 library which required that the device be
3667openable in read/write mode in order to determine its size. This
3668caused e2fsck -n to require read/write access when it was not
3669previously necessary.
3670
3671Fixed a bug in e2fsck which casued it to occasionally fail the test
3672suite depending on which version of the floating point library it was
3673using.
3674
3675Fixed a bug in e2fsck so that it now halts with a fatal error when
3676certain superblock consistency checks fail. Previously it continued
3677running e2fsck, with some potential confusing/damaging consequences.
3678
3679Added new flag to fsck which allows the root to be checked in parallel
3680with other filesytems. This is not the safest thing in the world to
3681do, but some system administrators really wanted it.
3682
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00003683Fixed -Wall flames in lib/ss.
3684
Theodore Ts'o74becf31997-04-26 14:37:06 +00003685
3686E2fsprogs 1.02 (January 16, 1996)
3687=================================
3688
3689Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
3690
3691Change e2fsck to print statistics of how many non-contiguous files are
3692on the system. Note that a file which is larger than 8k blocks, it is
3693guaranteed to be non-contiguous.
3694
3695In mke2fs, print a warning message if a user tries to format a whole
3696disk (/dev/hda versus /dev/hda1). If a user really wants to format a
3697whole disk, the -F (force) option forces mke2fs to format a whole disk
3698as a filesytem.
3699
3700Fix a bug in fsck where in some cases it might start checking
3701partitions in the next pass before it finishes checking partitions in
3702the current pass. This still won't cause two partitions on the same
3703disk will be checked, so it's rarely a problem in real life.
3704
3705Patch lsattr so that it won't hang when checking a named pipe.
3706
3707Minor compilation fixes:
3708 * Fix the order of libraries that were linked in debugfs.
3709 * Allow the sources to be compiled with -ansi turned on.
