Theodore Ts'o34a26112006-03-29 20:40:23 -05001E2fsprogs 1.39-WIP (March 29, 2006)
2===================================
3
4Dumpe2fs will now print the size of the journal (if present).
5
6Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
7between 2**31 and 2**32 blocks.
8
9Fix mklost+found so that it creates a full-sized directory on
10filesystems with larger block sizes.
11
12Fix a file descriptor leak in blkid library.
13
14Change mke2fs to use /etc/mke2fs.conf as a configuration file to
15configure the filesystem features, blocksize, and inode_ratio for
16different filesystem types.
17
18The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
19filesystem device node in exclusive mode to prevent accidents by
20system administrators. In the case of resize2fs and mke2fs, it will
21only use exclusive mode if the filesystem is not mounted.
22
23Fixed a bug in mke2fs which caused it to to fail when creating the
24resize inode for large filesystems. (Addresses Debian Bug #346580)
25
26Add support for on-line resizing to resize2fs.
27
28Fix blkid library so that logic to determine whether or not a device's
29cached information in /etc/blkid.tab needs to be verified or not
30doesn't get confused by a system clock which is insane (for example,
31if the battery is dead on a Macintosh running PPC Linux. (Addresses
32Red Hat Bug: #182188)
33
34The blkid library will now store the UUID of the external journal used
35by ext3 filesystems, so that in the future, the userspace mount binary
36can use this to find the location of the external journal and pass
37this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -050038
39E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -050040control how various options should be handled. See the e2fsck.conf
41man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -050042
Theodore Ts'o34a26112006-03-29 20:40:23 -050043E2fsck now prints an explanatory message when delaying a filesystem
44check when the system is running on battery. (Addresses Debian Bug:
45#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -040046
Theodore Ts'o4c02c412005-12-09 19:20:01 -050047E2fsck will detect if the superblock's last mount field or last write
48field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -050049#327580) These problems will be fixed automatically in preen mode
50since Debian's boot sequence bogusly doesn't set the time correctly
51until potentially very late in the bootup process, and this can cause
52false positives which will cause users' systems to fail to boot.
53(Addresses Debian Bugs #343662 and #343645)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -040054
Theodore Ts'o34a26112006-03-29 20:40:23 -050055E2fsck now checks to see if the superblock hint for the location of
56the external journal is incorrect, and if so, offer to update it.
57(Addresses Debian Bug: #355644)
58
Theodore Ts'of2b74cd2005-08-22 01:20:23 -040059Fix e2fsck from segfaulting on disconnected inodes that contain one or
60more extended attributes. (Addresses Debian Bug: #316736, #318463)
61
Theodore Ts'o4c02c412005-12-09 19:20:01 -050062E2fsck will stop and print a warning if the user tries running a
63read/write badblocks test on a read-only mounted root filesystem.
64
Theodore Ts'of3227852005-12-31 16:45:29 -050065When resizing a file containing a filesystem, resize2fs will expand or
66truncate a file as necessary. (Addresses Debian Bug: #271607)
67
Theodore Ts'o4c02c412005-12-09 19:20:01 -050068Fix mke2fs so that it correctly creates external journals on
69big-endian machines (such as a S/390).
70
71Fix debugfs's set_inode_field command so it can properly set the frag,
72fsize, uid_high, gid_high, and author fields in the inode instead of
73silently failing, and so that setting the i_size actually sets i_size
74correctly.
75
76Add a new debugfs command, set_current_time, which sets fs->now so
77that regression test suites can repeatedly modify the filesystem's
78last_write fields.
79
Theodore Ts'o34a26112006-03-29 20:40:23 -050080Fix a bug in debugfs's icheck which would incorrectly report the owner
81of an extended attribute block.
82
Theodore Ts'o4c02c412005-12-09 19:20:01 -050083Fix a display bug in "badblocks -sv" so that the done message properly
84clears the block number at the end of the test. (Addresses Debian Bug
85#322231)
86
Theodore Ts'of2b74cd2005-08-22 01:20:23 -040087Allow fractional percentages to the -m option in mke2fs and tune2fs
88(Addresses Debian Bug: #80205)
89
90Use fstat/fstat64 in getsize.c if the the target is a regular file,
91instead of attempting to do a binary search. Fix some fd leaks in
92error cases.
93
Theodore Ts'o34a26112006-03-29 20:40:23 -050094Add support for device mapper library to the blkid library to ensure
95that the "best" (i.e., leaf) device is probed by the blkid library.
96
Theodore Ts'o4c02c412005-12-09 19:20:01 -050097Fix the blkid library so that it notices when an ext2 filesystem is
98upgraded to ext3.
99
100Improve the blkid's library VFAT/FAT detection; it now understands
101labels stored in the root directory, and is more paranoid about
102checking the FAT superblock values.
103
Theodore Ts'o34a26112006-03-29 20:40:23 -0500104Fixed a fd leak in the uuid library which was causing problems for the
105LVM tools. (Addresses Debian Bug: #345832)
106
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500107Add support for the reiser4 and software suspend partitions to the
108blkid library. Also add support for extract the label from iso9660
109filesystems.
110
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400111Fix a compile_et bug which miscount the number of error messages if
112continuations are used in the .et file.
113
114Add extra sanity checks to protect users from unusual cirucmstances
115where /etc/mtab may not be sane, by checking to see if the device is
116reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
117#319002)
118
Theodore Ts'o34a26112006-03-29 20:40:23 -0500119Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
120Bug: #343149, #341911, #300871, #316604, #316782, #330789)
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500121
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400122Fix use-after-free bug in e2fsck when finishing up the use of the
123e2fsck context structure.
124
Theodore Ts'o34a26112006-03-29 20:40:23 -0500125Fixed spelling mistakes, typos, and otherwise clarified man pages and
126documentation. (Addresses Debian Bugs: #329859, #322188, #316811,
127#312515, #351268, #357951, #347295, #316040)
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500128
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400129Fixed various Debian packaging issues --- see debian/changelog for
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500130details. (Addresses Debian Bugs #317862, #320389, #290429, #310950,
Theodore Ts'o34a26112006-03-29 20:40:23 -0500131#310428, #330737, #330736, #329074, #356293)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400132
133Programmer's notes:
134-------------------
135
Theodore Ts'o34a26112006-03-29 20:40:23 -0500136Fixed the Makefile so that they work correctly on newer versions of
137GNU make (i.e., 3.81).
138
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400139Add valgrind support to the regression test suites, and eliminate
140false positives from valgrind.
141
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500142Add a regression test suite for the blkid library.
143
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400144Fix a fencepost error in resize2fs caught by valgrind.
145
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500146Fix compiler warnings about missing memcpy prototypes.
147
148We no longer have the sparc assembly code in the header file any more,
149so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
150break compiles on the sparc architectures when using gcc.
151
152In the libext2fs library, add the new field fs->now which if non-zero
153is used instead of the system time when setting various filesystem
154fields (last modified time, last write time, etc.)
155
156Fix gcc 4.01 complaints by adding a missing #include <string.h> to
157ext2fs.h which is needed since the inline functions use memcpy().
158(Addresses Sourceforge Bug #1251062)
159
160Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
161the build system when building files in the util directory which are
162needed during the build process. This avoids potential problems when
163cross-compiling and some of the options specified in CFLAGS or LDFLAGS
164are not recognized as valid by the host compiler. (Addresses
165Sourceforge Bug #1261547)
166
167Clean up the blkid library by making the superblock and generic i/o
168functions to be more generic. Clean up interface to the probe
169function, and fix memory leak. Finallly, remove an unneeded reference
170to probe.h in the lib/blkid/resolve.c
171
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500172Add an ext2fs_read_bb_FILE regression test to confirm proper detection
173of invalid block #'s.
174
Theodore Ts'o34a26112006-03-29 20:40:23 -0500175The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
176indicate that the the function read/writes the memory location.
177
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500178Fix various gcc -Wall complaints.
179
180Add a dependency to make sure that the subdirectories are created
181before creating all of the object files, in order to address parallel
182build problem in the library Makefiles. (Addresses Sourceforge Bug:
183#1261553)
184
185Add $(LDFLAGS) to the command line argument when generating an ELF or
186Solaris shared library, to allow cross-compile and other builds that
187might need to specify -L paths to needed libraries. (Addresses
188Sourceforge Bug #1261549)
189
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400190
Theodore Ts'ofea95ff2005-07-01 17:31:55 -0500191E2fsprogs 1.38 (June 30, 2005)
Theodore Ts'o1f965c82005-06-30 20:06:45 -0400192==============================
193
194Fix blkid's test programs (built with "make check") compile correctly
195even without "configure --enable-blkid-debug".
196
197Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
198type aliasing rules on newer gcc compilers. (Addresses Red Hat
199Bugzilla ##161183.)
200
201Fix com_err library to make it more compatible with recent changes
202made to the com_err library in MIT Kerberos V5 version 1.4.
203(Addresses Sourcefroge Bug #1150146)
204
205General cleanup of messages printed by e2fsprogs programs for grammar,
206consistency, and to make life easier for translators. Fixed a few
207strings containing English that had not been marked as needing
208translations. Removed strings that do not need to be translated, to
209make life easier for translators.
210
211Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
212test to see if a device appears to be in use instead of just relying
213on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
214
215Fix portability problem in the filefrag program affecting platforms
216where the size of an integer is smaller than the size of a long.
217(Addresses Debian Bug #309655)
218
219Mke2fs will now use a larger journal by default for filesystems
220greater than 4GB. (128 MB instead of 32MB).
221
222Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
223unless forced. This is to avoid signed vs. unsigned kernel bugs in
224block numbers that still need to be fixed.
225
226The blkid program has a new option which will more efficiently search
227for device when it is known (or expected) that only one matching
228device will be found in the system, such as when doing a lookup by
229UUID.
230
231Debian's e2fsprogs-specific initrd fragment will avoid including
232unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
233and LD_LIBRARY_PATH, and filtering out libraries found in
234/etc/ld.so.preload. (Addresses Debian Bug: #304003)
235
236Fixed a potential portability issue in the blkid programs for
237architectures where the char type is unsigned. (Addresses Sourceforge
238Bug: #1180585)
239
240Fix a bug in filefrag so that it doesn't falsely count an extra
241discontinuity when the first block found is an indirect block.
242(Addresses Debian Bug #307607).
243
244Fix blkid's recognition of cramfs filesystems, and enhance it to be
245able to handle cramfs labels.
246
247Fix debugfs's stat command to not core dump when a filesystem is not
248open.
249
250Fix e2fsck's handling of error conditions caused by the resize inode
251claiming blocks that are also used by other inodes, a filesystem
252corruption which was commonly caused by a bug in Fedora Core 3's
253resize2fs program.
254
255Fixed bug in filefrag which caused it to fail on non-ext2/3
256filesystems. (Addresses Debian Bug: #303509)
257
258If the superblock last mount time indicates that the system clock may
259not be accurate, then e2fsck will omit checking inodes' deletion time
260field for indications of a potential corrupted orphaned inode list.
261(Previously e2fsck only ommited these LOW_DTIME checks when the
262superblock's last write time looked insane.)
263
264Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
265(Addresses Debian bug #302200)
266
267Make the blkid library more paranoid about being run from setgid
268programs, and to use __secure_getenv() from libc if it is available.
269
270Fixed spelling mistakes, typos, and otherwise clarified man pages.
271(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
272and Sourceforge Bug: #1189803)
273
274Updated and fixed translations.
275
276Fixed various Debian packaging issues --- see debian/changelog for
277details.
278
279Programmer's notes:
280-------------------
281
282Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
283changed to take an unsigned int for the bit number. Negative bit
284numbers were never allowed (and didn't make any sense), so this should
285be a safe change. This is needed to allow safe use of block numbers
286greater than or equal to 2**31.
287
288The compile_et program will avoid recreating generated foo_err.c and
289foo_err.h files if no changes are necessary. The compile_et program
290will also atomically replace these files to avoid a potential parallel
291build race problem on SMP systems. (Addresses Sourceforge Bug:
292#1157933)
293
294Added a new function to the blkid library, blkid_probe_all_new(),
295which only probes newly added disk devices, and change
296blkid_find_dev_with_tag() to use this function so that when a
297requested tag is not found, devices that were previously not checked
298are searched before searching all devices in the system.
299
300Added new functions to the blkid library, blkid_dev_set_search() and
301blkid_dev_has_tag().
302
303E2fsck's problem strings can now use @m and @n as abbrevations for
304"multiply-claimed" and "invalid", respectively.
305
306The e2fsprog.pot file now has an explanation of how the @-expansion
307and %-expansion works, and strings in e2fsck/problem.c which contain @
308characters now have comments in e2fsprogs.pot with the @-expansion to
309make life easier for translators.
310
311Fixed missing return values in the ext2fs library which could cause it
312to return random garbage in certain error conditions.
313
314Allow the current time to be overriden via the E2FSCK_TIME environment
315variable for use in regression tests.
316
317The test scrpit driver program now exits with a non-zero status if
318there any of its test that it ran failed.
319
320Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
321Bug: #1157933)
322
323Fixed "make check" so that it compiles correctly even when e2fsprogs'
324header files have not be installed in the system include directories.
325(Addresses Sourceforge Bug: #1180572)
326
327Fixed gcc -Wall nits.

Theodore Ts'ofd4b28e2005-03-21 22:37:03 -0500330E2fsprogs 1.37 (March 21, 2005)
331===============================
332
333Add support for checking the validity of Extended Attributes stored in
334inodes to e2fsck.
335
336Add support for dumping the contents of large inodes to debugfs,
337including the extended attributes stored in inodes.
338
339Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
340when we create a new inode we make sure that the extra information in
341the inode (any extra fields in a large inode and any ea-in-inode
342information) is initialized correctly. This can take place when
343mke2fs creates the root and lost+found directory, when e2fsck creates
344a new root inode or a new lost+found directory, and when the user uses
345the debugfs write, mknod, or mkdir commands. Otherwise, the newly
346create inode could inherit garbage (or old EA information) from a
347previously deleted inode.
348
349Fixed a bug in e2fsck so it would notice if a file with an extended
350attribute block was exactly 2**32 blocks, such that i_blocks wrapped
351to zero.
352
353Added support to filefrag to detect files which are using the new
354experimental file extents format, and use the non-ext2 algorithm in
355that case. Fixed a bug to avoid reporting a false discontinuity if
356there is one or more unallocated blocks at the beginning of a file.
357
358Duplicated a check for noticing whether or not the number of blocks
359(given a certain blocksize) is greater than 2**32 when the
360BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
361allows mke2fs to automatically use a larger blocksize when creating a
362filesystem on a very large device when run on systems that do not
363support BLKGETSIZE64.
364
365Fix the I18N build which was broken in e2fsprogs 1.36 because the
366build system had been switched to treat the .gmo files as shipped
367files (for backwards compatibility with systems that have older GNU
368I18N tools installed), but the gen_tarball.in script was still
369removing the .gmo files from the official source distribution.
370
371Fixed various Debian packaging issues --- see debian/changelog for
372details. (Addresses Debian Bugs ##296769, #299341)
373
374Programmer's notes:
375-------------------
376
377Added new functions to the e2p library which convert between a string
378and os_type: e2p_os2string() and e2p_string2os(), and used them to
379make the generated binaries more compact.
380
381Fixed a compile-time error on Darwin systems.
382
383Cleaned up the lib/ext2fs Makefile slightly.
384

Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500386E2fsprogs 1.36 (February 4, 2005)
387=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500388
389All of the patches that were applied to Fedore Core 3's
390e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
391lot of bug fixes first. Users of Fedora Core 3 are strongly
392encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
393
394Add support for filesystem with the online resizing via resize inode
395feature. Fixed numerous bugs from the Fedora patches. The Fedora
396patches also didn't bother to do any consistency checking on the
397resize inode, or add any tests to the regression test suite. The "-R
398resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
399being listed in mke2fs's usage message. All of these shortcomings
400have been corrected.
401
402E2fsck can also also fix filesystems trashed by Fedora's resize2fs
403program. In order to do this, the user must run the commands:
404
Theodore Ts'od0a3b462005-05-05 22:57:44 -0400405 debugfs -w /dev/hdXXX -R "features ^resize_inode"

407
408Optionally, the ext2prepare command can be used to re-enable online
409resizing after the filesystem has been fixed.
410
411The fsck program will now accept an optional filedescriptor argument
412to the -C option. (The Fedora version of this patch would sometimes
413cause fsck to ignore a parameter on fsck's command line in some rare
414cases, sigh.)
415
Theodore Ts'odc256972005-01-26 13:20:12 -0500416Make sure e2fsprogs doesn't write garbage into the reserved portion of
417large inodes.
418
419Make sure resize2fs releases the blocks belonging to the old inode
420table blocks when moving the inode table. (Addresses Debian Bug:
421#290894)
422
423Skip the r_resize_inode test if resize2fs is not compiled (due to
424configure --disable-resizer)
425
426E2fsck now checks the summary filesystem accounting information, and
427if any of the information is obviously wrong, it will force a full
428filesystem check. (Addresses Debian Bug #291571)
429
430Fix e2fsck to not complain when the resize_inode feature is enabled,
431s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
432the resize inode.
433
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500434Fix e2fsck to note delete symlinks that contain an extended attribute
435after the ext_attr feature flag has been cleared. (Addresses Red Hat
436Bugzilla #146284).
437
Theodore Ts'odc256972005-01-26 13:20:12 -0500438Add new utility program, copy_sparse.c, which is very useful
439for dealing with large sparse files (such as e2image files).
440
441Add support for jnl_blocks[] for debugfs's set_super_value.
442
443Fix filefrag so that it works correctly with sparse files.
444
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500445Filefrag -v will print first and last blocks.
446
Theodore Ts'odc256972005-01-26 13:20:12 -0500447Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
448and dumpe2fs.
449
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500450Add mke2fs support so that it can support filesystems larger than 4TB
451automatically, by retrying with a 4k blocksize if the device size is
452too big to be expressed using a 1k blocksize. (Addresses Sourceforge
453bug #1106631)
454
Theodore Ts'odc256972005-01-26 13:20:12 -0500455Change blkid to test for NTFS first because Windows sometimes doesn't
456clear enough of the parition to confuse the probing routines into
457thinking the old filesystem type is still valid. (Addresses Debian
458Bug #291990)
459
Theodore Ts'o66fa0de2005-01-11 14:39:55 -0500460Add support for swap partition label and uuid's in the blkid library.
461
Theodore Ts'odc256972005-01-26 13:20:12 -0500462Add support to the blkid library to recognize Oracle ASM volumes.
463
464Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500465not just the first one, and work more consistently when the blkid
466cache file is not available or set to /dev/null. (Addresses Debian
467Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -0500468
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500469Badblocks will now correctly display block numbers greater than
470999,999,999 in its progress display.
471
472The tune2fs program will not allow the user from setting a ridiculous
473number of reserved blocks which would cause e2fsck to assume the
474superblock was corrupt. E2fsck's standards for what is a ridiculous
475number of reserved block has also been relaxed to 50% of the blocks in
476the filesystem.
477
478The blkid library will return vfat in preference to msdos, and ext3 in
479preference to ext2 (if the journalling flag is set) so that mount will
480do the right thing. (Addresses Debian bug #287455)
481
482Mke2fs will now use the -E option for extended options; the old -R
483(raid options) option is still accepted for backwards compatibility.
484Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
485
486Mke2fs will now accept a size in megabytes, gigabytes, and other units
487(via "32m" or "4g" on the command line) if the user finds this more
488convenient than specifying a block count.
489
490Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
491cache conherency problem.
492
493Debugfs now supports a new command, set_inode_field, which allows a
494user to manually set a specific inode field more conveniently, as well
495as set entries in the indirect block map.
496
497Debugfs's set_super_value command has been enhanced so that the user
498can set most superblock fields, including the date/time fields and
499some of the more newsly added superblock fields.
500
501E2fsprogs programs now accept an offset to be passed to the file
502specifiers, via the syntax: "/tmp/test.img?offset=1024".
503
504E2fsprogs programs will now accept blocksizes up to 65536; kernel
505support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500506other architectures with page sizes greater than 4k. There are 2.6
507kernel patches out there which enable this, but they are of this
508writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500509
Theodore Ts'o4ee558f2005-01-19 02:20:04 -0500510The e2image command now takes the -s option which will scramble
511directory entries for raw image files.
512
513Fix a file descriptor leak in the filefrag program.
514
515Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
516present.
517
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500518Fix bug in debugfs where kill_file would lead to errors when deleting
519devices and symlinks. (Sourceforge Bugs #954741 and #957244)
520
521Fix bug in the blkid library when detecting the ocfs1 filesystem
522
523Remove obsolete EVMS 1.x and a.out DLL support.
524
525E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -0400526
527Fixed two potential ordering constraint problems in e2fsck which might
528cause the filesystem to be corrupted if e2fsck is interrupted during a
529(extremely narrow) race window. Thanks to Junfeng Yang from the
530Stanford Metacompilation group for pointing this out.
531
532Fixed bug in e2fsck where it would not accurately detect whether or
533not the system is running on adaptor if the ACPI device representing
534the AC adapter didn't correspond to the what was used on IBM
535Thinkpads.
536
537Change e2fsck to accept directories greater than 32MB.
538
539Fix e2fsck so that a checkinterval of zero disables a time-based check
540of the filesystem.
541
542Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
543to the PAGER environment variable. (Addresses Debian Bug #239547)
544
545Tune2fs will not mark rewrite the superblock if the feature bitmasks
546are not modified.
547
548The debugfs program will set the filetype information when creating a
549link.
550
551Add debugfs -d option to use a separate source of data blocks when
552reading from an e2image file.
553
554Add e2image -I option which allows the e2image metadata to be
555installed into a filesystem.
556
557Fixed bug in the badblocks program which caused "done" to always
558appear in english even when a translation was available. (Addresses
559Debian Bug #252836)
560
561The blkid program has a new option -o which controls the output format
562of the blkid program; this is makes blkid more convenient to use in
563shell scripts.
564
565Fix a minor bug in uuid library, which was not using the full 14 bits
566of clock sequence when generating UUID's.
567
568Fix a Y8.8888K problem in the uuid library.
569
570Logsave now creates a new session id for itself to avoid getting
571killed by init whan transitioning between init levels.
572
573Change the licensing of the UUID library to be the 3-clause BSD-style
574license; this allows Apple to use the uuid library in Darwin.
575
576Add ocfs and ocfs2 probe support into the blkid library.
577
578Fix a memory and file descriptor leak in the blkid library.
579
580The blkid library will revalidate the device if the system time is
581earlier than last verification time of the device, since that
582indicates that the system time is probably nottrustworthy.
583
584The blkid library will override the default location of the blkid.tab
585file by the BLKID_FILE environment variable, if it is available.
586
587Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
588
589Add various portability fixes for lame new versions of glibc, Darwin
590and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500591Bugs #239934, #264630, #269044, #255589, #289133)
592
593Add support for Windows 9x/NT under Cygwin.
Theodore Ts'o48301122004-09-19 08:23:41 -0400594
595Updated and clarified various man pages. (Addresses Debian Bugs #236383,

Theodore Ts'o48301122004-09-19 08:23:41 -0400597
598Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
599
600Update the rpm spec files so that it works better with Fedora core 2
601and RH9.
602
603Fixed various Debian packaging issues (see debian/changelog). In
604particular, fixed the Debian initrd scripts. (#241183, #248050,
605#253595, #247775)

608Programmer's notes:
609-------------------
610
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500611Fixed various gcc -Wall warnings.
Theodore Ts'o48301122004-09-19 08:23:41 -0400612
613The uuid library now has new functions uuid_unparse_upper() and
614uuid_unparse_lower() which forces the case of the hex digits to be
615upper case, or lower case.
616
617The build process has been speeded up by enhancing the subst program
618to update the modtime on the generated files even when the generated
619file hasn't changed.
620
621The uuid library now uses C99 stdint.h types instead of custom types.
622
623Updated config.guess and config.sub with newer versions from the FSF.
624
625Removed out of date .cvsignore files from the source distribution.
626
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500627The ext2fs_unlink() function will return an error if both the name and
628inode number are unspecified, to avoid doing something surprising
629(such as unconditionally deleting the first directory entry).
630Directory entries are now deleted by coalescing them with the previous
631directory entry if possible, to avoid directory fragmentation. This
632is not an issue with the e2fsprogs suite, but may be a problem for
633some of the users of libext2fs, such as e2tools.
634
635Add support for version numbers of the form "1.36-rc1".
636
Theodore Ts'o48301122004-09-19 08:23:41 -0400637Fix build of mke2fs.static.
638
Theodore Ts'odc256972005-01-26 13:20:12 -0500639Add basic ext2fs library support for large (EA in inode) inodes.
640
Theodore Ts'o48301122004-09-19 08:23:41 -0400641The test_io mechanism can now abort after n reads or writes to a
642particular block. The block is specified by TEST_IO_BLOCK environment
643variable, and the read/write count by the TEST_IO_READ_ABORT and
644TEST_IO_WRITE_ABORT environment variables. The block data is now only
645dumped if the 0x10 bit is set in TEST_IO_FLAGS.
646
647UUID_DEFINE() in the uuid library now creates a static variable, with
648__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
649be used in header files.
650
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500651Add support for the install-strip and install-shlibs-strip targets, as
652suggested by the GNU coding guielines. "make install" no longer
653strips the binaries which are installed.
654
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500655Remove support for the --enable-old-bitops configure option which was
656only for very old sparc systems.
657
658Remove support for --enable-clear-htree; this was only needed during
659the early development of the htree patch.
660
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500661Use Linux-kernel-style makefile output so it is easier to see compiler
662warnings.
663
664Update gettext files to version 0.14.1.
665
666Update to use autoconf 2.5x.
667
668Improved support for compiling e2fsprogs under dietlibc.
669
Theodore Ts'o4ee558f2005-01-19 02:20:04 -0500670Make e2fsprogs portable to Solaris and FreeBSD systems.
671
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500672Add blkid_verify(), blkid_get_library_version(), and
673blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -0500674
675Add pkg-config files for e2fsprogs's libraries.
676
677Fix "make uninstall" to so that it removes everything that is installed.
678
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500679Add a configure --enable-maintainer-mode option which enables the
680makefile rules to rebuild the configure script from configure.in, and
681to reubuild the .gmo files in po directory.
682
683Drop the sparc assembly bitwise operations; it's less efficient
684than the GCC 3.4 compile code and triggers compiler warnings on
685sparc64. Thanks to Matthias Andree for his analysis and suggestions.

690==================================
691
Theodore Ts'o48301122004-09-19 08:23:41 -0400692E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500693preserves the existing badblocks list.
694
Theodore Ts'o48301122004-09-19 08:23:41 -0400695Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500696
697E2fsprogs will now deal correctly with symlinks that contain
698extended attribute information, which can be created using SE Linux.
699(Addresses Debian Bug #232328)
700
701Remove a double longjump into an invalid stack frame bug in e2fsck.
702(This was during an abort sequence, which normally worked on Linux and
703caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500704
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500705Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
706(the NLS library will replace "" with the .po header information).
707
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500708Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
709dump due to a division by zero error. (Addresses Debian bug #207082)
710
Theodore Ts'o151a7162003-12-26 14:04:33 -0500711Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
712when reconnecting a directory requires creating a lost+found
713directory. (Addresses Debian bug #219640).
714
715Fixed a bug where e2fsck would bomb out if a journal needed to be
716replayed when using an alternate superblock.
717
Theodore Ts'o48301122004-09-19 08:23:41 -0400718E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500719if the laptop is running on battery. The next time fsck runs while
720the system is on the AC mains, or after the grace period is exceeded,
721the filesystem will be checked. (Addresses Debian bug #205177)
722
723E2fsck will inform the user when there are 5 or fewer mounts before a
724filesystem check will be forced. (Addresses Debian bug #157194)
725
726Fix e2fsck's handling of corrupted indirect blocks in the bad block.
727We now correctly handle the case where there is an overlap between a
728block group descriptor or a superblock and a bad block indirect block.
729In the case where the indirect block is corrupted, we now suggest
730"e2fsck -c".
731
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500732Fix byte swap bugs in e2fsck that caused the journal backup location
733in the superblock and symlinks created by SE Linux to be cleared
734by e2fsck on big-endian machines. (Addresses Debian bug #228723)
735
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500736E2fsck -c now replaces the current list of bad blocks with the ones
737found by badblocks.
738
739Fix bugs in e2fsck and tune2fs which could cause a core dump if a
740non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
741
742Fix a potential bug in e2fsck which could cause it to core dump when
743trying to print the location of the backup superblock.
744
745Protect against a potential core dump in e2fsck when printing a
746message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400747
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400748Add support for backing up the journal inode location in the
749superblock. E2fsck will automatically save the journal information in
750the superblock if it is not there already, and will use it if the
751journal inode appears to be corrupted. ext2fs_add_journal_inode()
752will also save the backup information, so that new filesystems created
753by mke2fs and filesystems that have journals added via tune2fs will
754also have journal location written to the superblock as well.
755Debugfs's logdump command has been enhanced so that it can use the
756journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500757
758E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400759
760Shrink the size of the e2fsck executable by moving some initialized
761variables to the BSS segment.
762
763E2fsck will avoid printing the ^A and ^B characters which bracket the
764progress bar when stdout and stdin are a tty device instead of a pipe
765to another program. (Addresses Debian bug #204137)
766
Theodore Ts'o151a7162003-12-26 14:04:33 -0500767Debugfs's mkdir command will automatically expand the directory if
768necessary. (Addresses Debian Bug: #217892)
769
770Fixed a bug in debugfs so that copying a file from /dev/null uses the
771correct mode bits. (Addresses Debian Bug: #217456)
772
773If the environment variables DEBUFS_PAGER and PAGER are not set,
774debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -0500775/usr/bin/pager, and then falling back to 'more' and 'less'.

788
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500789Fix bug in uuid library when there is no network card and the library
790is generating a time-based uuid. The random MAC address was not

Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400795
796Fix bug in badblocks when using O_DIRECT; we need to make sure that
797we're reading from an offset which is page aligned. For read-only and
798read-write tests, we try to recover after an error so that we can
799continue reading on page-aligned boundaries. (Addresses Debian Bug
800#203713)

Theodore Ts'ob70b1162004-02-28 10:52:35 -0500802Badblocks now checks 64 blocks at a time instead of 16. (Addresses

812Programmer's notes:
813-------------------
814
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500815Fixed a build problem so that e2fsprogs would compile with the
816--enable-profile option to configure selected. (Addresses Sourceforge
817bug #811408)
818
819Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
820Bugzilla Bug #112448)
821
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500822Centralize code which calculates the location of the superblock
823and block group descriptors so that it is in a single library routine.
824
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400825Added two new functions, ext2fs_file_open2() and
826ext2fs_inode_io_intern2() which take a pointer to an inode structure.
827
828Fix compile_et to output the correct prototype for
829initialize_xxx_err_table_r() in the header file. (Addresses Debian
830bug #204332)
831
832In the lib/et makefile, make sure com_err.info is deleted on "make clean".
833
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400834Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
835present. This is for when we try stuffing an int into void * pointer.
836
837Fix type-punning which can cause gcc 3.x to miscompile code by getting
838confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
839and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
840**'. The EVMS code uses an ugly union approach since we don't want to
841modify the EVMS interfaces.
842
843Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
844aid build process on systems can use invoke GNU make as "gmake".
845
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500846Added regression testing for mke2fs.
847
848Fixed gcc -Wall nitpicks.
849
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500850Fixed various compiler warnings.
851
852Add portability fixes for FreeBSD and for using fsctl under Darwin to
853support ext2 ioctl's.
854

Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400856E2fsprogs 1.34 (July 25, 2003)
857===============================
858
859Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
860a tight loop while waiting for a child fsck to exit in some cases.
861This burns CPU times which slows down the low-level filesystem check.
862
863Added code to mke2fs to assure that the default block size for a
864filesystem is at least as big as the sector size of the device, if it
865can be determined.
866
867Changed mke2fs and resize2fs to round the default size of a filesystem
868to be an even multiple of the VM pagesize in order to avoid a Linux
869kernel bug introduced when the storage of the buffer cache was moved
870into the page cache.
871
872Mke2fs will warn the user when creating a filesystem with journaling
873and a blocksize greater than 4096. (Addresses Debian bug #193773)
874
875Fixed a bug in resize2fs which caused it to fail on filesystems with a
876non-empty bad block list. Resize2fs now discards any blocks on the
877badblock list which are no longer part of the filesystem as the result
878of a filesystem shrink. (Note: this means that shrinking and then
879enlarging a filesystem is no longer a reversible operation;
880information about bad blocks in the part of the filesystem which is to
881be chopped off will be lost.)
882
883Changed resize2fs so the user can use prefixes to specify the units of
884the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
885and to make the error and informational messages explicitly display
886the blocksize used by the filesystem, in order to avoid confusion.
887(Addresses Debian bug: #189814)
888
889Added a new debugfs command, dump_unused, which dumps the contents of
890all unused blocks to stdout. (Useful as an emergency try-to-find
891deleted data command.)
892
893Added a new debugfs command, imap, which prints the location of a
894specified inode in the inode table.
895
896Fixed a bug in the badblocks program which caused it to use one bit of
897randomness in its non-destructive read/write test, instead of using a
898full 8 bits of randomness.
899
900Added a new option (-t) to badblocks, which allows the user to control
901the test pattern(s) used when checking a disk.
902
903The blkid probe function now more correctly detects UDF filesystems.
904
905Fixed a bug in the blkid library which caused it to not update its
906cache if a filesystem changes from having a label to not having a
907label.
908
909Fixed a bug in the blkid library wihch could avoid an infinite loop
910in blkid_find_dev_with_tag() if /proc is not mounted and there the
911/etc/blkid.tab file has not yet been created.
912
913Fixed the badblocks program so that the destructive read/write test
914honors the -c option, and to use O_DIRECT when possible to avoid
915thrashing the system block buffer cache.
916
917Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -0400918 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400919 - Removed testing NYC translation
920 - Fixed NLS support for message abbrevations in e2fsck
921 - Remove de-utf.po, since we shouldn't have two versions using different
922 charset encodings.
923 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
924 simplify the statistics reporting in e2fsck.
925
926Changed configure.in so that its defaults for *BSD systems no longer
927build an fsck wrapper, and not to install in /usr/local by default.
928
929Fixed some minor spelling errors/typo's in e2fsck and the configure
930script.
931
932Fixed various Debian packaging issues (see debian/changelog).
933
934Updated and clarified man pages. (Addresses Debian Bug #195616)
935
936Programmer's notes:
937-------------------
938
939Fix gcc -Wall nitpicks.
940
941Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
942NLS support by default. (Added partial workaround for gettext/Darwin
943incompatibility problems.)
944
945Added full MIT KRB5 and Himdall compaibility support to the com_err
946library and the compile_et program. (Addresses Debian bug #191900)
947
948Added the blkid_known_fstype() function to the blkid library, which
949returns true if it is passed a filesystem type which is recognized by
950the blkid probing functions.
951
952Improved the documentation for the blkid library.
953
954Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
955returns the hardware sector size of a device, if it is available.
956
957Added a dependency in the blkid library's .so file to the uuid
958library, since the former uses the latter. (Addresses Debian bug
959#194094)
960
961Added --with-diet-libc and --disable-evms to the configure script.
962
963Fixed a minor memory leak in the badblocks program.
964
965Fixed a portability problem in tune2fs --- not all systems have strptime().
966
967Fixed a portability problem in debugfs with the use of getopt() more
968than once. Old-style BSD, new-style BSD, and Linux C libraries all do
969things differently.
970
971Add support Windows support to ext2fs_get_device_size().
972
973Added (normally disabled) debugging code to the Unix I/O manager which
974causes it to disable all userspace caching if the NO_IO_CACHE is
975defined.
976
977Changed the test I/O manager so it can always be linked into e2fsck,
978mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
979configure script. The test I/O manager will only print any debugging
980information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
981variables are set, which specifies which I/O operations are logged and
982a block number to watch, respectively. The log messages are sent to
983stderr by default, unless a filename is specified via the
984TEST_IO_LOGFILE environment variable.
985
986
Theodore Ts'o71df0dc2003-04-21 16:17:09 -0400987E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400988===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500989
Theodore Ts'oba142c12003-04-16 00:59:59 -0400990Added a new utility program, logsave, which captures the output of a
991command in a log file, even if the containing directory hasn't been
992mounted yet (in which case the it saves the output in memory until it
993can write out the logfile). This is useful for capturing the
994output of fsck during the boot sequence.
995
996Fixed some portability problems that were causing problems under
997the Cygwin32 environment.
998
999Mke2fs now interprets a negative number to the -b option as a minimum
1000block size.
1001
1002Fixed a bug in mke2fs which was incorrectly checking the argument to
1003the -g option if the default block size was used. (Addresses Debian
1004bug #188319)
1005
1006Fsck now explicitly ignores tmpfs and devpts, and it will complain if
1007it can not find filesystem checkers for jfs, reseirfs, and xfs.
1008
1009E2fsck now updates the global free block and inode counters from the
1010block group specific counters quietly. This is needed for an
1011experimental patch which eliminates locking the entire filesystem when
1012allocating blocks or inodes; if the filesystem is not unmounted
1013cleanly, the global counts may not be accurate.
1014
1015Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
10162.0 is not yet supported; this only pulled in the bug fixes: fixed
1017possible hangs caused by bugs in calling waitpid, and not setting the
1018pipe to non-blocking mode; also fixed a file descriptor leak; made
1019sure all functions call log entry/exit functions.)
1020
1021Badblocks now flushes its output file as bad blocks are discovered.
1022
1023The uuid library is now more paranoid about assuming the correctness
1024of the /dev/random device; it mixes in a stream of bytes from
1025random/srandom, just in case.
1026
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001027Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04001028maintainer of e2fsprogs. Other various Debian-specific packaging
1029cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001030
1031Move the source tarball generation functions from the top-level
1032makefile to the util/gen-tarball script.
1033
1034Updated the Turkish .po translation file.
1035
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001036Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001037it more compatible with com_err libraries from those distributions.
1038
1039Changed dumpe2fs to always display the superblock fields relating to
1040the journalling and/or directory indexing feature even if those
1041features are not enabled.
1042
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001043Updated and clarify copyright statement vis-a-vis alpha releases of
1044e2fsprogs.
1045
1046The ss library will now try to dynamically link to the readline
1047library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04001048the debugfs program now has line editing and history features. The
1049SS_READLINE_PATH environment variable is used to find a readline or
1050readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001051
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001052E2fsck now finds most duplicate filenames (all when rebuilding all
1053directories via the -D option) and offers to delete or rename
1054duplicate filenames/directory entries. (Addresses Debian Bug #176814).
1055
1056Fix bug in e2image. When writing out a raw image file, include data
1057blocks from symlinks that do not store the symlink within the inode.
1058
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001059Fix bug in resize2fs which incorrectly moved the block and inode
1060bitmaps for sparse superblock filesystems and incorrectly marked
1061blocks as in use. (Addresses Debian bug #174766)
1062
1063Added a new shared library, the blkid library, which efficiently
1064allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
1065and UUID filesystem specifiers without needing to search all of the
1066devices in the system. Instead, the device is looked up in a cache
1067file, and then verified to make sure the blkid cache is correct.
1068
1069Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
1070the device name, using the blkid library. (Addresses Debian bugs
1071#166048, #179671)
1072
1073Fsck now supports backslash escapes in /etc/fstab so that \040 can be
1074used for spaces in device labels.
1075
1076Removed 32-bit limitations for debugfs's dump command.
1077
1078If the user specifies a large number of inodes, Mke2fs will
1079automatically adjust the number of blocks per group to find a valid
1080set of filesystem parameters.
1081
1082Add workaround to detect broken MD devices where when some of the
1083underlying devices are marked read-only, writes to the MD device are
1084silently dropped. E2fsck will detect if there is an attempt to run
1085the journal twice, and abort with an error if this is the case.
1086(Addresses IBM Bugzilla bug #1226)
1087
1088E2fsck will print an error if more than one of the -p/-a, -n or -y
1089options are specified.
1090
1091E2fsck will fix HTREE corruptions in preen mode, without stopping the
1092boot process. This is needed because the 2.4 ext2 filesystem
1093accidentally had the INDEX_FL backwards compatibility code removed.
1094
1095Mke2fs no longer creates filesystems with the dir_index flag set by
1096default; the user has to specifically request it.
1097
1098Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04001099#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001100
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001101Created man page for the mk_cmds program (from the libss library).
1102
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001103Programmer's notes:
1104-------------------
1105
1106Fix various gcc -Wall nits.
1107
1108Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001109successfully under Solaris and Apple/Darwin.
1110
1111Fixed a Makefile dependency to allow building e2fsprogs using parallel
1112make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001113
1114Changes to create a subset distribution which consists only of the
1115et, ss, uuid, and blkid libraries. The configure script and top-level
1116makefile were changed to support working with a subset distribution.
1117
Theodore Ts'oba142c12003-04-16 00:59:59 -04001118Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
1119actually used, and might people who are looking for
1120EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
1121
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001122Updated debian files to fix a number of Lintian warnings.
1123
1124Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001125
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04001126Removed unnecessary libraries from being linked into the fsck, lsattr,
1127chattr, and blkid executables.
1128
Theodore Ts'o38513012002-11-09 15:00:56 -05001129E2fsprogs 1.32 (Nomvember 9, 2002)
1130==================================
1131
1132Fixed a bug in the Unix I/O routines which caused needless writebacks
1133of clean blocks from the unix_io cache (they were erroneously marked
1134as being dirty, so they were getting written back to disk before
1135getting evicted from the disk cache). This was harmless, but it
1136significantly slowed down e2fsck.
1137
1138Made some other minor optimizations to the Unix I/O routines to save a
1139small amount of CPU time.
1140
1141Updated internationalization files.
1142
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001143
Theodore Ts'oae65b292002-11-08 20:08:48 -05001144E2fsprogs 1.31 (Nomvember 8, 2002)
1145==================================
1146
1147Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
1148compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
1149handling for child process that die unexpectly. Add a hack to force
1150mkfs to create filesystems that won't cause problems with hardware
1151that has 2k or 4k minimum blocksize requirements. Read from child
1152processes in non-blocking mode, so that the GUI continues to update.
1153
1154Fix e2fsck so that it returns the appropriate exit code when the root
1155filesystem has been changed, so that system's rc scripts will be told that
1156the system needs to be rebooted.
1157
1158Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
1159was set, some of the descriptor blocks that should have been written
1160out were getting skipped.
1161
1162Changed e2fsck to force out changes to the backup copies of the
1163superblock and block group descriptors when important changes are made
1164to those data structures.
1165
1166Fix a bug where e2fsck could erroneously mark a filesystem as being
1167clean if a check of dirty filesystem is interrupted with a ^C. (Bug
1168introduced in e2fsprogs 1.28.)
1169
1170If journal debuging is enabled using --enable-jbd-debug, the debugging
1171level is now set via the E2FSCK_JBD_DEBUG environment variable.
1172
1173If byteswapping support is disabled using configure --disable-swapfs,
1174skip the tests which depend on byte-swapping, so that "make check"
1175won't bomb out.
1176
1177Lshattr will now display the indexed directory flag. Also, some of
1178the more esoteric compression flags are supressed unless compression
1179support has been enabled.
1180
1181Update man pages.
1182
1183
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001184E2fsprogs 1.30 (October 31, 2002)
1185=================================
1186
1187When resizing a filesystem, and inodes need to moved, resize2fs will
1188update the inode's ctime field, and the mtime field of the containing
1189directories, so that incremental backups using dump/restore will work
1190correctly.
1191
1192In order to avoid spurious errors, e2fsck wil check the last
1193superblock write time to determine whether or not it can safely use
1194the LOW_DTIME checks to determine if there are inodes on the orphan
1195inode linked list that had somehow gotten disconnected. (Addresses
1196Sourceforge bug #620980)
1197
1198Partition in /proc/partitions that being with the string "lvm" are
1199considered real partitions even if they do not end with a number.
1200
1201Fixed a bug in the the uuid generation function, where if /dev/urandom
1202is not present, but /dev/random is, and there isn't sufficient
1203entropy, the get_random_byte function could spin a loop forever.
1204
1205E2fsck, mke2fs, etc. will now reliably notice when image files are
1206mounted using the loopback interface. (Addresses Sourceforge bug
1207#619119)
1208
1209When flushing buffers (as is done by badblocks, for example) check to
1210see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
1211FDFLUSH ioctl which causes the MD device driver which causes confusing
1212syslog messages about obselete ioctl messages. (Addresses Sourceforge
1213bug #545832).
1214
1215Debugfs's write command now checks to see if the destination filename
1216exists before creating it. (Addresses Sourceforge bug #478195.)
1217
1218When installing man pages, search for compressed man pages using all
1219commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
1220
1221Fixed a bug in fsck where multiple filesystems specified on the
1222command were not being checked in parallel due to a logic bug
1223introduced to support the FSCK_MAX_INST environment variable.
1224
1225We have added a new superblock field, s_mkfs_time, which indicates
1226when a filesystem was created. It is set via mke2fs, and printed out
1227by dumpe2fs, but is not actually touched by the kernel.
1228
1229Dumpe2fs has been made more robust by not aborting if there is an
1230error reading the block/inode bitmaps; instead it will still print out
1231the location of the block/inode bitmaps and inode table.
1232
1233Add support for the an alternative block group descriptor layout which
1234allows for on-line resizing without needing to prepare the filesystem
1235in advance. (This is the incomat feature flag meta_bg.)
1236
1237Add support for storing default mount options in the superblock, so
1238that the filesystem can be mounted with specific mount options without
1239needing to specify them on the mount command line or in the /etc/fstab
1240file.
1241
1242Add support for a new inode flag, which is to be used for indicating
1243the top of directory hierarchies for the Orlov block allocator.
1244
1245Fix e2fsck so that if it creates the lost+found directory, it does so
1246with the more apporpriate permissions of 0700. Also change
1247mklost+found so that it also creates the directory 0700.
1248
1249Fixed format bug in e2fsck if NLS is in use.
1250
1251Add a German translation for e2fsprogs's NLS support.
1252
1253Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
1254the beginning of the inode table. This won't matter much, since if
1255there is a bad block at the beginning of the inode table, the root
1256directory won't be available. But at least e2fsck won't crash in this
1257case.
1258
1259Fixed endian problems in the htree code for e2fsck and debugfs.
1260
1261When byte-swapping a filesystem on a PPC architecture, byte-swap the
1262bitmaps since the historical big-endian ext2 variant had byte-swapped
1263bitmaps, and the ext2fs library assumes this. This fixes the
1264regression test suite on PPC machines.
1265
1266Fix e2image so that it handles a bad block in the inode table
1267appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04001268
1269E2fsck now uses a more sophisticated algorithm to salvage corrupted
1270directories that recovers more information in the corrupted directory
1271block.
1272
1273E2fsck now performs additional consistency checks on indexed (HTREE)
1274directories.
1275
1276Fix bug where efsck might get confused about whether a completely
1277empty directory block is an empty leaf block or an interior htree
1278node. This could cause e2fsck to get confused into think that a valid
1279indexed directory was corrupted.
1280
1281E2fsck no longer creates an empty directory entry at the end of a
1282directory block when optimizing a directory. This would cause some
1283earlier versions of the dxdir kernel code to corrupt the directory
1284when attempting to split a node containing an empty directory entry.
1285
1286E2fsck could sometimes in rare circumstances leave the indexed flag
1287set after a small directory was optimized by compressing it instead of
1288indexing it. (This should never happen in real life, since
1289directories that small wouldn't have been indexed, but better safe
1290than sorry.)
1291
1292E2fsck now only updates the master superblock in all cases. This
1293slightly shortens its run time.
1294
1295Ext2ed can deal with directory entries of length 0; previously it
1296would get stuck in an infinite loop.
1297
1298Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
1299specifiers. (Sourceforge patch #613447)
1300
1301Badblocks will now work correctly on read-only devices such as
1302CD-ROM's. (Sourceforge patch #600451)
1303
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001304Updated and clarified man pages. (Addresses Debian bug #167108)

Theodore Ts'oc6633052002-09-24 01:26:50 -04001307E2fsprogs 1.29 (September 24, 2002)
1308===================================
1309
1310Fixed a bug in e2fsck which could corrupt a directory when optimizing
1311it (via the -D option) or rebuiliding the hash tree index with a 1 in
1312512 probability, due to a fence post error.
1313
1314Fixed a bug in the LVM support code which caused LABEL='xxx' not to
1315work correctly.
1316
1317Mke2fs now enables the directory indexing flag by default. (Since
1318this is a compatible feature flag, it's safe to do so.)
1319
1320Tune2fs will support setting the directory indexing feature flag. It
1321will automatically set up the default hash algorithm and hash seed
1322fields in the superblock.
1323
1324If the bone-headed user enters the root filesystem twice in
1325/etc/fstab, the -R option which skips the root filesystem will skip
1326all of them. (Addresses Debian bug #159423). Note! This is not a
1327precedent for dealing intelligently with any other kind of doubled
1328entry in /etc/fstab!
1329
1330
1331Programmer's notes:
1332-------------------
1333
1334Removed perror declaration in lib/et/internal.h. All modern systems
1335can be expected to define perror() these days. Besides, the lib/et
1336code wasn't using perror at all anyway. :-)

Theodore Ts'ob7bad612002-08-31 03:00:33 -04001339E2fsprogs 1.28 (August 31, 2002)
1340================================
1341
1342Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
1343for setting the htree flag is not included yet, although it can be
1344manually turned on via the debugfs program.
1345
1346Clarified e2fsck error message which is printed when it cannot find
1347sufficient contiguous block when relcating filesystem metadata.
1348
1349Added support for building an EVMS plugin module for ext2/3. This
1350module is substantially the same as the EVMS module shipping with EVMS
13511.1, with one or two bugfixes. E2fsprogs can also build this plugin
1352for use with EVMS 1.0 (which did not include the ext2 plugin module),
1353if the configure --enable-old-evms flag is given.
1354
1355Fsck will search through EVMS volumes when trying to resolve
1356filesystem specifications such as LABEL=xxx or UUID=xxx.
1357
1358Added a new utility program, /sbin/findfs, which will return
1359filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
1360the device name.
1361
1362Update and clarified various man pages. (addresses Debian Bug #145044,
1363#146437, #131350, #151990, #144621, #141938)
1364
1365If there are no filesystems specified on fsck's command line, fsck now
1366treat that as if the -As options were given. Previously it would
1367simply do nothing. (Addresses Debian Bug #153102)
1368
1369Mke2fs no longer treats a failure to be able to clear the MD signature
1370at the end of the filesystem as a fatal error. (Addresses Debian Bug
1371#155007)
1372
1373The e2p library functions (which are used by lsattr and chattr) now
1374double check to make sure the file is a regular file or directory
1375before attempting to use the ext2 ioctls. Some device drivers
1376unfortunately respond to the ext2 ioctl's with unknown behaviour.
1377(Addresses Debian Bug #152029).
1378
1379The extended attribute handling has been updated to correspond with
1380the latest V2 bestbits ACL code.
1381
1382Fixed bug in e2fsck which caused it to not clear the dtime field when
1383processing truncated inodes on the orphan list. This could cause data
1384loss(!) if a filesystem is rebooted before a truncate has been
1385committed.
1386
1387E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
1388algorithms. This makes e2fsck much faster in the case of severely
1389corrupted filesystems where a large number of blocks are claimed by a
1390large number of inodes. (Thanks to the 2.5 IDE device driver for
1391inspiring this work.)
1392
1393Resize2fs has been significantly sped up when shrinking and expanding
1394a filesystem by a very small number of blocks (for example, when EVMS
1395is converting a partition to be an EVMS legacy volume).
1396
1397Added a new option to e2fsck, -D, which will optimize or compress all
1398of the directories in the filesystem.
1399
1400E2fsck now catches SIGINT and SIGTERM to make sure it will can
1401properly clean up and only exit at safe points. Fsck will pass
1402SIGINT/SIGTERM to its child processes, and wait until they have all
1403exited before it exits.
1404
1405The uuid parsing code in the uuid library now properly complains when
1406an illegally formated uuid is presented to it. (Addresses Debian bug
1407#152891)
1408
1409Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
1410and 2.4.17, since the workaround can cause problems when using a 2.4
1411kernel with an old version of glibc built with the 2.2 headers.
1412
1413Fixed a bug in mke2fs where it wasn't properly clearing the initial
1414superblock used by other filesystems. (Addresses Debian bug #147256.)
1415
1416Added support for the synchronous directory feature written by Andrew
1417Morton.
1418
1419The debugfs program can delete directories using the rmdir command.
1420
1421Add support for 8k and 16k filesystems (for systems with page sizes
1422that are greater or equal to 8k or 16k, respectively). Note that
1423these filesystems can not be mounted on x86 systems, or other systems
1424with only 4k page sizes, due to limitations in the current Linux VM
1425code.
1426
1427Resize2fs requires that the filesystem state be valid and have no
1428errors; otherwise, e2fsck -f must be run first. (Previously it simply
1429required that the last fsck time be greater than the last mount time.)
1430
1431Configure now defaults the man pages directory to /usr/share/man on
1432Linux systems.
1433
1434E2fsck now offers to truncate inodes which contain too many blocks (so
1435that i_blocks would overflow. Also fixed handling of large sparse
1436files.
1437
1438E2fsck now more completely checks for symlink validity, including
1439requiring NULL termination and length checks.
1440
1441E2fsck will offer to try forcing a disk write to remap a bad block
1442after finding a read error when reading a filesystem metadata block.
1443
1444Fixed a bug in debugfs which caused the -b and -s options to crash
1445debugfs, as well as breaking the testb, setb, and clearb functions.
1446
1447Added a bmap command to debugfs which calculates the logical to
1448physical block mapping for a particular inode.
1449
1450Fixed a bug in code which checked to see if a device was mounted which
1451sometimes (rarely) failed in the case of a plain file.
1452
1453Fixed a bug in resize2fs where when it reported an error, it would
1454print a message erroneously indicating that the filesystem had been
1455resized before it aborted.
1456
1457When resizing a plain file which is smaller than the requested size,
1458resize2fs will attempt to extended the file so that programs like
1459e2fsck will not complain that the file is too small.
1460
1461Resize2fs will print the actual new size of the filesystem when it is
1462finished resizing.
1463
1464Fixed a bug in debugfs where "ls -l" would report incorrectl file type
1465information on big-endian systems.
1466
1467
1468Programmer's notes:
1469-------------------
1470
1471Fixed collisions with C++ reserved words.
1472
1473Added portability fixes for building e2fsprogs on the HURD and AIX.
1474
1475Added the ext2ed program for creation of test cases. (ext2ed has many
1476limitations and bugs which make it unsuitable for production use.)
1477
1478The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
1479flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
1480name_len field is byte swampped on big-endian machines, since in the
1481V2 structure, name_len is a char field which is doesn't need to be
1482byte swapped --- except if an old-style kernel had byte-swapped the
1483name_len field as part of the V1 structure.
1484

Theodore Ts'oa8e77242002-03-08 03:12:14 -05001486E2fsprogs 1.27 (March 8, 2002)
1487==============================
1488
1489The warning messages for mke2fs now go to standard error.
1490
1491Fixed to make sure "make check" runs all of the test programs with
1492LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
1493
1494The mke2fs program checks the boot sector for the BSD disk label, and
1495avoids erasing it if it is there.
1496
1497Fixed a bug in e2fsck which caused it to core dump if the journal
1498inode was missing when it was supposed to be there.
1499
1500E2fsck now prints ranges in pass 5 when printing deltas for the block
1501and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001502
1503Debugfs's "ls -l" command now will print out the file type information
1504in the directory entry.
1505
1506Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
1507mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
1508
1509Debugfs can now examine the experimental directory indexing
1510information.
1511
Theodore Ts'oa471ac52002-03-05 03:37:06 -05001512Fixed bug in debugfs which caused it to core dump if modify_inode is
1513called without an open filesystem.
1514
1515The debugfs lsdel command now runs its output through a pager first.
1516
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001517When installing manual pages, remove the compressed manual pages first.
1518
1519Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
1520
1521Fix the 2.4 resource limitation workaround introduced in 1.26 which
1522actually broke things on mips32, sparc32, and Alpha platforms.
1523
Theodore Ts'oa471ac52002-03-05 03:37:06 -05001524Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
1525(which is required by the newer libintl libraries).
1526
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001527Programmer's notes:
1528-------------------
1529
Theodore Ts'oa8e77242002-03-08 03:12:14 -05001530Fixed various gcc -Wall complaints.
1531
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001532Fixed a few memory leaks in the e2fsck journaling code, and in the
1533ismounted code checking for a swap device.
1534
1535Add new inode I/O abstraction interface which exports an inode as
1536an I/O object.
1537
1538Exported ext2_file_flush as a public interface.
1539
1540In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
1541
1542Lots of small random portability fixes to make e2fsprogs build under
1543AIX --- even without the 5L compatibility toolkit, and even using the
1544uber-crippled AIX native C compiler.
1545
1546
Theodore Ts'o06987392002-02-03 01:36:54 -05001547E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001548=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001549
Theodore Ts'o446314f2001-12-24 15:22:27 -05001550Dumpe2fs will keep going now if the bad block inode can't be read.
1551(Previously it stopped with a fatal error.)
1552
1553E2fsck will now give an opportunity to run the journal even if the
1554recovery flag is not set. This is the default behaviour if e2fsck is
1555using a backup superblock, since the needs_recovery flag will never be
1556set in the backup superblock copies.
1557
1558E2fsck now automatically finds the backup superblock/group descriptors
1559even when the primary superblock is completely destroyed for 2k and 4k
1560filesystems. (Previously it just guessed/assumed that we were dealing
1561with a 1k filesystem in that case, and users had to manually specify
1562the backup superblock number.)
1563
1564Fixed a bug in e2fsck where it dereferences a null pointer when there
1565is a problem opening a filesystem in preen mode.
1566
1567E2fsck now handles external journals correctly; previously it trashed
1568the external journal device if the journal needed to be replayed.
1569
1570Work around ulimit incompatibility problem caused by recent 2.4
1571kernels; the unix IO module will automatically try to set any resource
1572limits to be infinite on startup.
1573
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001574Fixed a bug in e2fsck where it wasn't allocating a new block or inode
1575bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001576 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001577
1578E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
1579clearing the new V2 fields if they do not make sense or if the ext3
1580superblock is version 1 superblock.
1581
1582E2fsck will automatically relocate the ext3 journal from a visible
1583file (i.e., /.journal) to an hidden inode if the filesystem has been
1584opened read/write. This allows the users to add a journal while the
1585filesystem is mounted, but the next time the system is rebooted, the
1586journal file will disappear. This avoids problems with backups,
1587stupid operators with superuser bits, etc.
1588
1589Fix a bug in fsck where it would not support a filesystem type of
1590"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
1591
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001592Fsck now supports fstab entries of the form "ext3,ext2". It will also
1593automatically identify reiserfs filesystems.
1594
1595The number of processes spawned by fsck can now be limited using the
1596FSCK_MAX_INST environment variable.
1597
Theodore Ts'o446314f2001-12-24 15:22:27 -05001598Fsck now searchs the LVM proc hierarchy to find logical volumes which
1599should be searched for UUID and label information.
1600
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001601Work around a bug in 2.4.10+ kernels by trying to unset the filesize
1602limit if at all possible, when opening a block device. (The filesize
1603limit shouldn't be applied against writes to a block device.)
1604
Theodore Ts'o446314f2001-12-24 15:22:27 -05001605In mke2fs and e2fsck, specifying the -c option twice will now do
1606a read/write test on the disk. Update the man pages to encourage
1607using the -c option, and to discouraging running badblocks separately,
1608since users tend to forget to set the blocksize when running
1609badblocks.
1610
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001611Mke2fs now automatically clears the immutable attribute on a
1612pre-existing .journal file left over from a previous failed attempt to
1613add a journal to an alreadyy-mounted filesystem.
1614
1615Fixed mke2fs's exit codes to consistently indicate when the mke2fs
1616operation failed.
1617
Theodore Ts'o446314f2001-12-24 15:22:27 -05001618Mke2fs now creates the lost+found directory with permissions of 0700,
1619so that files that had previously lived in protected directory are
1620safe if they get dropped in lost+found and the system administrator
1621doesn't deal with immediately. (Addresses Debian #bug 118443)
1622
1623Mke2fs and e2fsck (and all programs that use the
1624ext2fs_check_if_mounted function) will now properly identify that a
1625device is mounted, even in cases where devfs has confused things with
1626multiple devices names with the same identity, or if a dim-witted
1627system administrator has done something stupid like creating device
1628file aliases in their home directory. Also now checks for swap devices
1629by using /proc/swaps. (Addresses Debian bug #106622)
1630
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001631Added a new option (-T) to tune2fs which sets the time a filesystem
1632was last checked.
1633
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001634Speed up e2image when creating sparse raw image files by optimizing
1635away excess lseek() system calls.
1636
1637Fix support of large (> 2GB) files when used as a filesystem in
1638mke2fs, tune2fs, debugfs, and findsuper.
1639
1640Debugfs's stat and icheck commands now properly deals with large (>
16412GB) files.
1642
1643Debugfs's set_super_value command now prints out the list of valid
1644superblock fields which can be set using the command.
1645
Theodore Ts'o446314f2001-12-24 15:22:27 -05001646Debugfs's rm and kill_file command now updates the superblock free block
1647and inode counts, thus keeping the filesystem consistent.
1648
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001649Debugfs's lsdel command now takes an optional argument which allows
1650the user to only see the most recently deleted files.
1651
1652A new command (undel) was added to debugfs which automates
1653undeleting a deleted inode and linking it back to a directory.
1654
1655Debugfs's ls command now takes a new option, -d, which lists
1656deleted directory entries.
1657
1658Debugfs's testb, freeb, setb, and find_free_block commands now take an
1659optional count argument.
1660
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001661Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
1662be used to signal that a particular inode should not be eligible for
1663tail-merging --- this is needed for programs like LILO.
1664
1665The findsuper (an unreleased, uninstalled utility program) has been
1666improved to add extra validity checks and to add a progress meter.
1667(It is still an unsupported program; the officially supported way to
1668recover from a trashed partition table is to use gpart; findsuper is
1669for wizards only. :-)
1670
1671Debugfs was fixed to compile with "configure --disable-swapfs".
1672
Theodore Ts'o446314f2001-12-24 15:22:27 -05001673Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001674
1675Added new translation file for Turkish.
1676
Theodore Ts'o446314f2001-12-24 15:22:27 -05001677Programmer's notes:
1678-------------------
1679
1680Fix general gcc -Wall complaints.
1681
1682E2fsprogs (mostly) works with the dietlibc.
1683
1684The programming texinfo file has been expanded to include description
1685of additional libext2fs functions. (Still not compeltely done, but a
1686lot of the more important functions have been documented.)
1687
1688Added a umask structure to struct_ext2_filsys, which currently only
1689modifies the behaviour of ext2fs_mkdir(), but if we add any file
1690creation functions to libext2fs, we should also make sure they respect
1691the umask setting.
1692
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001693The build-rpm script was fixed to be a bit more safe.
1694
1695The tests' Makefile now has a way of automating test case creation
1696for e2fsck, using "make testnew".
1697
1698Created a new function, ext2fs_dir_iterate2 which passes more
1699information to the callback function (identical to the one used by
1700ext2fs_dblist_dir_iterate). The directory iterator functions take a
1701new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
1702directory entries. If the directory entry is deleted, the callback
1703function will be called with the entry paraemter set to
1704DIRENT_DELETED_FILE.
1705
1706Added new functions, ext2fs_inode_alloc_stats and
1707ext2fs_block_alloc_stats, which takes updates block/inode allocation
1708statistics in the bitmaps, block group descriptors, and superblock
1709when inodes or blocks are allocated or deallocated.
1710

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04001712E2fsprogs 1.25 (September 20, 2001)
1713===================================
1714
1715This is primarily a bug-fix release; no new features were added, but
1716there are a number of embarassing bug fixes and cleanups applied.
1717
1718Fix a bug mke2fs which causes stack garbage to be written to disk when
1719zapping disk sectors. (This bug could cause mke2fs to core dump for
1720some kernels, I suspect with security enhancement patches.)
1721
1722Remove unneeded #include of <linux/config.h> which was breaking
1723building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
1724
1725Updated tune2fs man page to reflect the fact that adding or removing a
1726journal doesn't require running e2fsck.
1727
1728Remove use of AC_REQUIRE from autoconf which had been used to prevent
1729AC_CANONICAL_HOST from being called twice; unfortunately this causes
1730recent autoconf to bomb out since they don't allow AC_REQUIRE to be
1731used outside of autoconf macros. Fortunately, it doesn't seem to be
1732necessary any more, anyway.
1733
1734E2fsck will now not fall back to an alternate superblock if the user
1735specifies the superblock location explicitly on the command-line.
1736This allows easier recovery from a situation where the primary
1737superblock and block groups are slightly corrupted, but the backup
1738superblocks are completely broken.
1739
1740Fix problem which caused compile_et and mk_cmds to blow up if
1741e2fsprogs was in a directory with a pathname that contained spaces.
1742
1743We are now more paranoid about checking the entry in /etc/mtab to make
1744sure the filesystem is really mounted, since some broken distributions
1745(read: Slackware) don't initialize /etc/mtab before checking non-root
1746filesystems. (Slackware also doesn't check the root filesystem
1747separately, and reboot if the root filesystem had changes applied to
1748it, which is dangerous and broken, but there's nothing I can do about
1749that.)
1750
1751Make UUID library C++ friendly by adding appropriate extern "C"
1752declarations and using const in the function declarations.
1753
1754Fix up the com_err texinfo file so that it can product a valid info
1755file (previously, it could only be used to generate paper
1756documentation using texinfo.tex).
1757
1758
Theodore Ts'ofb707752001-09-04 15:00:37 -04001759E2fsprogs 1.24a (September 2, 2001)
1760===================================
1761
1762Fix brown-paper bug in mke2fs which caused it to segfault when
1763printing the version string.
1764
1765
Theodore Ts'o109624a2001-08-31 00:59:55 -04001766E2fsprogs 1.24 (August 30, 2001)
1767================================
1768
1769Revert the BLKGETSIZE64 support, since for some distributions, this
1770ioctl has been used by an unofficial kernel patch to update the last
1771sector on the disk, and this was causing disk corruption problems as a
1772result.
1773
1774Mke2fs is now more careful about zapping swap space signatures and
1775other filesystem/raid superblock magic values so that programs like
1776mount who try to use hueristics to determine the filesystem type of a
1777partition are less likely to be confused.
1778
1779E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
1780regular file (since Andreas Dilger's on-line resizing tools will set
1781its mode bits).
1782
1783Fixed some minor texinfo, man pages nits for spelling errors,
1784texinfo warnings, etc. (Addresses Debian bug #110621.)
1785
1786E2fsprogs program no longer print the filesystem version number
1787(i.e. 0.5b), since it only confuses people and doesn't serve any real
1788purpose.
1789
1790E2fsck will once again compile under libc5, since it will supply its
1791own version of strnlen if necesssary.
1792
1793mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
1794when specifying the external journal device. tune2fs will also search
1795devices looking for the externla journal debice when removing.
1796
1797E2fsprogs 1.23 (August 15, 2001)
1798================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001799
1800Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04001801correctly handle a filesystem with EA's and check the EA blocks for
1802corruptions.
1803
Theodore Ts'od494bba2001-08-09 06:14:42 -04001804E2fsck's symlink sanity checking has been cleaned up. It now checks
1805the i_size value of fast symlinks, and checks for immutable flags
1806being set of symlinks, etc.
1807
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001808E2fsck now offers to clear inodes which are special files that have a
1809non-zero i_blocks or i_size field. (The i_size field check was in the
1810previous version of the code, but due to a bug it didn't offer to
1811clear the inode unless i_size and i_size_high were both non-zero.)
1812
Theodore Ts'od494bba2001-08-09 06:14:42 -04001813E2image can now create "raw" image files, which only contain the
1814filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
1815debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001816
1817Add support for the 64-bit block device patches.
1818
1819Fixed bugs in creating external journals with a 1k blocksize.
1820
Theodore Ts'od494bba2001-08-09 06:14:42 -04001821Add initial support for external journals (so long as the external
1822journal only supports a single filesystem) in e2fsck.
1823
1824Remove requirement for needing to run fsck on a filesystem after
1825removing a journal (either internal or external).
1826
Theodore Ts'obf16d102001-07-27 22:20:06 -04001827The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001828
1829Speed up the check of an ext3 filesystems by avoiding a needless flush
1830of all of the superblock and block group descriptors.
1831
Theodore Ts'od494bba2001-08-09 06:14:42 -04001832Speed up creating an internal journal using tune2fs in the case where
1833the filesystem has a lot blocks already allocated.
1834
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001835Tune2fs has been fixed to make sure that only error messages go to
1836stderr, and normal message go to stdout. (Addresses Debian bug #108555)
1837
Theodore Ts'od494bba2001-08-09 06:14:42 -04001838Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001839now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04001840
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001841Add support in fsck for the filesystem type "auto".
1842
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001843Fsck -A will not try to interpret device names for filesystems which
1844have a pass number is 0. (Addresses Debian bug #106696).
1845
1846Fsck prints a warning message if now valid filesystems are passed to
1847it. (Addresses Debian Bug #107458.)
1848
Theodore Ts'o9249d982001-07-20 18:14:10 -04001849E2fsck now gives an explicit warning if there filesystem still has
1850errors at the end of the run. (Addresses Debian bug #104502)
1851
Theodore Ts'od494bba2001-08-09 06:14:42 -04001852E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001853reflects an error. E2fsck will also not run the orphan list if the
1854filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04001855
1856E2fsck now prints the number of large files when given the -v option.
1857
1858Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001859
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001860Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04001861
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001862
Theodore Ts'o19d6b542001-06-23 00:13:09 -04001863E2fsprogs 1.22 (June 22, 2001)
1864==============================
1865
1866Fixed a bug in e2fsck's handling of orphan inodes which are special
1867files (i.e., block/character device files, named FIFO's, etc.).
1868
1869Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
1870tune2fs to fail at adding a journal to a mounted filesystem.
1871
1872Fixed a few big-endian bugs in e2fsprogs
1873 * The directory block functions were accidentally reporting
1874 some directories as corrupted when they weren't.
1875 * If e2fsprogs is compiled --disable-swapfs, the C language
1876 equivalents weren't being included for big-endian platforms.
1877 (Fixes Debian bug #101686).
1878
1879Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
1880
1881Programmer's notes:
1882-------------------
1883
1884Use platform independent method of defining the BLKFLSBUF and FDFLUSH
1885ioctls, and allow them to be defined for non-i386 platforms.
1886
1887The uuid.h header file is now protected against multiple inclusions.
1888
1889E2fsprogs is now being developed using BitKeeper. Changed the test
1890scripts to deal with BK's stripping CR characgters from text files,
1891and changed the top-level Makefile.in to avoid including BitKeeper
1892files when generating the source tarball.
1893
1894
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001895E2fsprogs 1.21 (June 15, 2001)
1896==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00001897
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001898Added new configure flags which allow a subset e2fsprogs to be built;
1899this is most useful for boot floopies, since the resulting shared
1900libraries and programs are slimmed down by removing features that
1901aren't necessary for a boot floppy. The new flags that were added
1902are: --disable-swapfs, which removes support for byte swapping old
1903legacy PPC/68k filesystems, --disable-debugfs, which removes support
1904for debugfs from the libext2fs library, --disable-imager, which
1905removes support for the e2image program, and --disable-resizer, which
1906removes support for resize2fs.
1907
1908E2fsck now prints the number of mounts or days elapsed since the last
1909check when e2fsck is forced to check an otherwise clean filesystem.
1910
1911Tune2fs now prints an informative message about how often a filesystem
1912will be checked when adding a journal to the filesystem, to remind the
1913user that he/she may want to adjust those parameters using tune2fs
1914-c/-i.
1915
1916Worked around hurd brain-damage which causes e2fsck to sometimes
1917believe a filesystem is the root filesystem based on device numbers
1918(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
1919violation).
1920
1921Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
1922erroneous error with the -F option was specified.
1923
1924Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001925ext3 0.7a.
1926
Theodore Ts'o767de092001-06-02 01:20:18 +00001927Fixed two bugs in e2fsck's handling of dup block handling, dealing
1928with relatively uncommon edge cases: a directory with an indirect
1929block which is claimed by another file, and when the last inode in the
1930filesystem has blocks claimed by another file.
1931
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00001932E2fsck now checks to see if the i_size field of a fast symlink is too
1933big, and offers to clear the symlink if so.
1934
1935E2fsck now checks to see if i_size_high of special files is non-zero,
1936and offers to clear i_size_high.
1937
Theodore Ts'o767de092001-06-02 01:20:18 +00001938Fix e2fsck's handling of incompatible journal flags so that the user
1939has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00001940entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00001941
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001942Fixed a bug in fsck which could cause it to core dump if a mix of
1943standard and non-standard device names are used in /etc/fstab.
1944(Debian bug #100559)
1945
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001946Fixed a bug in debugfs which caused read errors when copying a file to
1947not be noticed.
1948
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001949The debugfs set_super_value command can now modify the s_lastcheck field.
1950
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001951Fixed a bug in lsattr and chattr which was accidentally introduced in
19521.20 to support > 2GB files; both lsattr and chattr wasn't reading
1953directories correctly because the change modified the layout of struct
1954dirent to be incompatible with the libe2p shared library.
1955
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001956Cleaned up the mke2fs manual page and included a discussion about why
1957it's good to periodically check the filesystem even when journaling is
1958enabled.
1959
Theodore Ts'o767de092001-06-02 01:20:18 +00001960Programmer's notes:
1961-------------------
1962
1963Fix general gcc -Wall complaints.
1964
1965The types needed by the ext2 header files are now provided by
1966lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
1967
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001968Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001969in ext2_types.h. Also, if linux/types.h has already been defined,
1970don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001971
Theodore Ts'o767de092001-06-02 01:20:18 +00001972Fixed make depend script so that it automatically corrects the
1973pathname cleanups performed by make -M, so I don't have to fix them up
1974by hand.
1975
1976Fixed the d_loaddump test case to be more robust, and not depend on
1977bash'isms.
1978
1979Removed debugfs's dependence on pread(), which was accidentally
1980intrudced in e2fsprogs 1.20
1981
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001982Fixed a performance bug in the libext2fs's icount routine; the size
1983estimate of the icount array was incorrectly being calculated.
1984
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001985Removed use of the badblocks compatibility functions in the e2fsprogs
1986programs.
1987
1988Added paranoia code which protects against strange cases where /etc
1989isn't on the root filesystem, or if /etc/mtab doesn't exist.
1990
1991The header file ext2_types.h is now installed.
1992
1993Autoconf is used to determine when we are on big-endian machines,
1994instead of doing run-time tests, to save a few bytes of code.
1995
1996The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
1997functions are no longer inline functions, which saves space and
1998doesn't really cost any real performance.
1999
2000The ext2fs library no longer depends on the e2p library. (What need
2001there was of it --- namely, fsetflags, was coded in-line).
2002
2003Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
2004when the user is stupid and tries compiling the package using "make
2005install" as root.
2006
2007Miscellaneous code cleanups:
2008 * Added missing files from Makefile.in's SRCS file, so that
2009 their dependencies would be properly calculated.
2010 * Removed redundant code
2011 * Fixed comments in code
2012 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002015E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002016=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00002017
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002018Add support for replaying the ext3 journal purely in user mode,
2019including handling the orphaned inode list. Used code contributed by
2020Andreas Dilger, with bug fixes and the orphaned inode handling done
2021by Theodore Ts'o.
2022
2023The mke2fs and tune2fs programs can create or modify a filesystem to
2024include an ext3 journal. Tune2fs also can be used to remove an ext3
2025journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002026
2027E2fsck will now check for the existence of a linked list of orphan
2028inodes in the superblock, and clear those inodes before starting the
2029rest of the filesystem check (but after the journal playback).
2030
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002031E2fsck now validates the file descriptor passed to the -C option,
2032which saves against the completion bar getting written to an
2033unexpected location, such as the disk being checked. (Debian
2034bug/wishlist #55220)
2035
2036E2fsck will now bump the filesystem revision number from zero to one
2037if any of the compatibility bits are set.
2038
2039Fixed a bug where a badly corrupted directory on a big endian system
2040could cause e2fsck to die with a bus error. The
2041ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
2042the ext2 library now does alignment sanity checks on the rec_len field
2043of the directory entry before using it.
2044
2045The ext2 library has been enhanced to make tune2fs safe to run on
2046mounted filesystems. (Users could usually get away with using tune2fs
2047on mounted filesystems before, but with the advent of ext3 and
2048journaling, it became important to make tune2fs was *really* safe for
2049use even when the filesystem being modified is mounted.) E2label is
2050now implemented by tune2fs using an argv[0] dispatch, so that e2label
2051is also now safe for use on mounted filesystems.
2052
2053Added a new program, e2image, which creates a backup of critical ext2
2054filesystem data structures. The generated image file can be examined
2055using dumpe2fs and debugfs. In the future, e2fsck will be able to use
2056the image file to help recover very badly damaged filesystems.
2057
2058Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
2059no longer cause e2fsck to bomb out. Also treat files > 2GB as being
2060large file when deciding whether or not the filesystem has large files.
2061
2062Fixed lsattr and chattr so that they work correctly on large files.
2063(Fixes Debian bug #72690.)
2064
2065Removed limitation in get_device_size() which imposed a one terrabyte
2066filesystem limitation. (Most 2.2 kernels still have a signed int
2067problem which cause 1 TB block device limitation. Fortunately, the
2068kernel patches to fix this are much easier than fixing the 2TB
2069limitation in the kernel. :-)
2070
2071A max_mount_count of zero is now treated as if no mount count were
2072set. (Previously, no mount count was indicated by using -1, and a
2073mount count of zero caused e2fsck to always be run.)
2074
Theodore Ts'o77648562001-05-14 13:04:44 +00002075Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002076
2077Mke2fs now adds some randomness in s_max_mount_count so that multiple
2078filesystems won't be all checked at the same time under normal
2079operations.
2080
Theodore Ts'o5570a652000-08-21 01:23:39 +00002081Fixed bug in the progress bar printing code which could cause e2fsck
2082to core dump on an illegal filesystem.
2083
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002084Fixed bug in fsck which could allow more than one instance of e2fsck
2085to be printing a progress bar. (Debian bug #65267)
2086
Theodore Ts'o5570a652000-08-21 01:23:39 +00002087Fsck using a UUID or a LABEL specifier will work even if devfs is
2088compiled into the kernel and not mounted. If the pathnames in
2089/proc/partitions are incorrect, fsck will search /dev for the correct
2090device (using the new ext2fs_find_block_device library function).
2091Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002092found when they are in use. Support has also been added to support
2093additional IDE disks and the DAC 960 device names. (Debian bug #94159)
2094
2095Fixed a bug in fsck which caused it not deal properly with 16
2096byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002097
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002098Fsck's -t option has been made a lot more flexible. The semantics for
2099what happens if a comma-separated list to fsck has been regularized,
2100and it is now possible to filter what filesystems will get checked
2101based what is in the filesystem's fstab entry's option field. (Debian
2102bug #89483.)
2103
Theodore Ts'o5570a652000-08-21 01:23:39 +00002104The dumpe2fs program can now print out the group description
2105information in hex, and also prints the location of the superblock and
2106block group descriptor for those block groups that have them.
2107
2108Mke2fs now clears the ext2 superblock before it starts creating a
2109filesystem, so that the superblock magic number is only written if the
2110filesystem creation process successfully completes.
2111
2112The debugfs program's stat command now pretty-prints the blocks used
2113by an inode so that it's more compact and informative.
2114
2115The debugfs stats command now uses the same libe2p code (which is used
2116by dumpe2fs) to print the superblock header information. This is more
2117complete, and it avoids a bit of code duplication.
2118
2119Added a new debugfs command, set_super_value (ssv) which allows the
2120user to set arbitrary superblock fields.
2121
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002122Debugfs was extended to support inode numbers in hex (by prefixing
2123them with 0x), and so that modify_inode can set the inode generation
2124number. Also, there is now a new function command called logdump
2125which will dump an ext3 journal.
2126
2127Fixed a bug in debugfs so that quitting out of the pager doesn't kill
2128debugfs.
2129
2130Debugfs's dump command now stops immediately upon reporting a disk
2131read error. (Fixed a bug in ext2fs_file_read library routine which
2132caused debugfs not to stop.) (Debian bug #79163)
2133
2134On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
2135checked before /etc/mtab is used, since /proc/mounts is more likely to
2136be accurate.
2137
2138Added portability fixes for Solaris and Linux/ia64.
2139
2140Various manual pages were clarified and cleaned up. (Fixed debian
2141bugs #63442, #67446, and #87216)
2142
Theodore Ts'o5570a652000-08-21 01:23:39 +00002143
2144Programmer's notes:
2145-------------------
2146
2147The e2fsck message printer now supports %Iu and %Ig, which will print
2148out the inode's user and group owners, respectively.
2149
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002150E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
2151that no longer dependent on the system having the correct version of
2152the kernel header files.
2153
Theodore Ts'o5570a652000-08-21 01:23:39 +00002154Added a new function to libext2, ext2fs_find_block_device(), which
2155searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
2156device given its device number.
2157
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002158Added a new function to libext2, ext2fs_sync_device, which centralizes
2159all of the places which might try to use the BLKFLSBUF or FDFLUSH
2160ioctls (and usually failing to define them since the system header
2161files don't usually do this for us, and we're trying to avoid usage of
2162kernel include files now).
2163
Theodore Ts'o5570a652000-08-21 01:23:39 +00002164Added new utility programs in tests/progs: random_exercise and
2165hold_inode. They aren't built by default; they're useful for
2166exercising ext3 filesystem code.
2167
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002168Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
2169the filesystem close functions to only update the superblock, and to
2170not touch the block group descriptors. Needed by tune2fs when
2171modifying a mounted filesystem.
2172
2173Got rid of struct ext2fs_sb and replaced it with the standard struct
2174ext2_super_block from include/linux/ext2_fs.h. Note: this may break
2175source (but not binary) compatibility of some users of the ext2
2176library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00002177replace of struct ext2fs_sb with struct ext2_super_block, and include
2178the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002179
2180The ino_t type has been renamed ext2_ino_t to protect applications
2181that attempt to compile -D_FILE_OFFSET_BITS=64, since this
2182inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
2183unexpected ABI change.
2184
2185The Makefiles have been reworked so that "make check" can be run from
2186the top-level Makefile.
2187
2188Fix general gcc -Wall complaints and removed dead code.
2189
2190Remove use of NOARGS, because we assume everyone does ANSI C these
2191days.
2192
2193Added build-rpm script from sct.
2194
2195New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
2196to support e2image.
2197
2198New function ext2fs_flush_icache which must be called if the
2199application program modifies the inode table blocks without going
2200through ext2fs_write_inode() interface.
2201
2202New ext2fs_check_mount_point() function, which will return the mount
2203point of a device if mounted.
2204
2205The io_channel abstraction now has an optional interface,
2206io_channel_write_range, which allows specific byte ranges to be
2207written.
2208
2209The unix_io IO channel now supports write-through caching, so that
2210journal creation is more efficient.
2211
2212Added x86 assembly language routines to support byte swapping, to
2213reduce executable size.
2214
2215Fixed bug in the utility program subst so that it's possible to
2216replace a substitution variable with a zero-length string.
2217
2218Fixed numbering e2fsck pass1 problem numbers; an extra zero had
2219slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002220
Theodore Ts'ob777e262000-07-27 01:39:23 +00002221E2fsprogs 1.19 (July 13, 2000)
2222==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00002223
2224Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00002225be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00002226
2227Add experimental support needed for the ext2 compression patches.
2228This requires compiling e2fsprogs with the --enable-compression flag
2229to the configure script.
2230
2231Added ext3 journalling support. E2fsck will run the journal (if
2232necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
2233installed as a symlink to e2fsck. Fsck has been taught about ext3,
2234and treats it the same as ext2 in terms of the progress bar logic.
2235Dumpe2fs will display the superblock journaling information if the
2236filesystem has a journal. The ext2 library will now permit opening an
2237ext3 filesystem with the recovery flag set. This is necessary for
2238on-line dump's to work correctly, but there may be issues with this
2239working well since ext3 is much less agressive about syncing blocks to
2240the filesystem, since they're safe on the journal.
2241
2242Tune2fs and e2fsck have been changed to allow the mount_count check to
2243be disabled by setting max_mount_count to -1. (This was already
2244supported by the kernel.)
2245
2246Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
2247are used for ext3 as well.
2248
2249Added internationalization support for e2fsprogs; must be enabled
2250by passing --enable-nls to configure.
2251
2252Always use the provided ext2fs header files to insulate ourselves from
2253kernel version changes. Which include files are used by e2fsprogs
2254have also been cleaned up to improve portability.
2255
2256Limit the number of times that e2fsck updates the progress bar so that
2257people who are booting using a 9600 baud console don't get swampped by
2258too many updates.
2259
2260Improved the loop detection algorithm in e2sck's pass #3 so that it is
2261much, much faster for large filesystems with a large number of
2262directories.
2263
2264The memory footprint for e2fsck is now slightly smaller than before.
2265
2266E2fsck now checks if special devices have a non-zero size, and offers
2267to clear the size field if it finds such an inode.
2268
2269E2fsck now checks if special devices have the append-only flag set,
2270and offers to clear the inode.
2271
2272E2fsck now properly handles some "should never fail" cases during a
2273bitmap copy in pass5.
2274
2275E2fsck now properly prints control characters in filenames as ^A .. ^Z.
2276
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002277E2fsck now calculates the correct location of the backup superblock in
2278the case of filesystem blocksizes > 1k.
2279
2280Fixed a bug in e2fsck's calculation of the number of inodes_per_block
2281which normally didn't cause problems under most filesystem parameters,
2282but could cause a valid superblock to be rejected in extreme cases.
2283Other checks for validating superblock values were made more
2284stringent.
2285
Theodore Ts'oab146762000-07-07 04:37:35 +00002286Added non-destructive write testing to the badblocks program, courtesy
2287of David Beattie. The badblocks also now has an option to input the
2288current set of bad blocks, so that known bad blocks are skipped to
2289speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00002290feature which causes badblocks to run until it has completed some
2291number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00002292
2293Badblocks now checks to see if the device is mounted and refuses to do
2294the tests involving writing to the device if it is mounted. Also,
2295badblocks now allows the number of blocks to be checked to be
2296defaulted to the size of the partition.
2297
2298Fixed a bug in fsck which didn't allow non-root users to be able to
2299check filesystems if there were any LABEL= or UUID= entries in
2300/etc/fstab.
2301
2302The Hurd doesn't support the filetype filesystem feature. The mke2fs
2303program now makes sure that for the Hurd, the filestype feature is
2304turned off. E2fsck will check to see if the filetype feature is
2305turned on for Hurd filesystems, and offer to turn off the feature.
2306
2307Mke2fs now has a safety check to make sure the number of blocks do not
2308exceed 32 bits even on a 64 bit platform.
2309
2310Really fixed a bug in fsck to allow "fsck -As" to run interactive
2311fsck's. (For those people who like to do interactive fsck's in the
2312/etc/rc scripts!?!)
2313
2314Debugfs has a few new features: the rdump command, which will do a
2315recursive dump of a directory and all of its contents, and the lcd
2316command which does a local chdir (much like the ftp command of the
2317same name). In addition, the debugfs program and the open_filesystem
2318command now takes three new options: -b and -s, which allows the
2319blocksize and superblock location to be specified, and the -c option
2320which is used in catastrophic situations where the block group
2321descriptors are corrupt. If the -c option is specified, debugfs will
2322skip trying to read in the block and inode bitmaps.
2323
2324Debufs's lsdel command was fixed to handle bad blocks in the inode
2325table.
2326
2327A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
23284 digit years.
2329
2330General improvements in error messages
2331
2332 - Mke2fs prints a sane error message if the partition size is zero
2333 (usually because the partition table wasn't reread by the
2334 kernel due to the partition being busy), instead of "invalid
2335 argument passed to ext2 library while initializing superblock".
2336
2337 - Fsck now prints more self-explanatory message if an invalid UUID=
2338 or LABEL= specification is passed to it.
2339
2340UUID library changed to use the LGPL.
2341
2342Fixed a bug in the UUID library where very rapid calls to the
2343time-based UUID generator could cause duplicate UUID's to be returned.
2344This was not a problem for e2fsprogs, but it could be a problem for
2345other users of the library.
2346
2347Make the UUID library more robust in the face of missing or an
2348improper /dev/urandom or /dev/random files.
2349
2350Added some random portability fixes for Solaris.
2351
2352Some minor man page updates.
2353
2354Fixed a memory leak in the ss library.
2355
2356
2357Programmer's notes:
2358-------------------
2359
2360We now try to use lseek64 and open64 from the LFS if possible.
2361
2362The 3rd parameter in e2p's print_flags is now a flags word, instead of
2363a boolean option.
2364
2365The mark and unmark bitmap functions now return the previous state of
2366the bit that was being changed, which is useful for some speed
2367optimizations.
2368
2369The following functions have been added to enhance the badblocks list
2370handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
2371ext2fs_badblocks_equal.
2372
2373The ext2 header files now have the latest journalling fields to the
2374superblock.
2375
2376The ext2fs_mkdir function in libext2fs now properly backs out of error
2377conditions robustly.
2378
2379Cleaned up makefiles:
2380 - to cleanly compile with the -j flag.
2381 - so distclean removes all generated files.
2382 - so in case of an error while installing header files, the make aborts.
2383
2384Fix test_script so that it works correctly when compiling in the
2385source directory.
2386
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002387The random UUID generation routine has been made slightly better in
2388the case where /dev/random doesn't exist. (Use of randomly-based UUID
2389is still not recommended if /dev/random doesn't exist, however; it's
2390better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00002391
2392Clean up the build process so it's more friendly in case of missing
2393directories.
2394
2395The ext2fs header file can now be #include'd into C++ programs.
2396
2397The e2p.h header file is now installed.
2398
2399Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
2400
2401
2402
Theodore Ts'o24ded091999-11-10 15:56:16 +00002403E2fsprogs 1.18 (November 10, 1999)
2404==================================
2405
2406Fix a core dumping bug in e2fsck if an imagic inode is present or
2407(more rarely) if the filesystem is badly corrupted enough that e2fsck
2408has to restart pass 1 processing. E2fsck now closes the filesystem
2409before freeing a large number of its data structures, so in the case
2410of future memory faults, at least the fixed filesystem will be fully
2411written out.
2412
2413If a filesystem doesn't support imagic inodes, and e2fsck discovers an
2414imagic inode, it will offer to clear the imagic flag.
2415
2416E2fsck will now offer to clear the immutable flag on special files
2417(device/socket/fifos) when running it in non-preen mode.
2418
2419E2fsck will now set the filetype when creating /lost+found, and when
2420connected orphaned inodes to /lost+found.
2421
2422Debugfs's ncheck and icheck commands now handles the case where there
2423are bad blocks in the inode table without bombing out.
2424
2425The badblocks list processing code has been made more efficiently for
2426appending a large number of (ordered) badblocks to the badblocks list.
2427
2428Some minor man page updates.
2429
2430Fsck now allows interactive e2fsck's when using fsck -As (not a common
2431mode, but some people like to do this in boot scripts for silly reasons).
2432
2433Programmer's notes:
2434-------------------
2435
2436The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
2437with the problem code convention.
2438
2439The badblocks list regression test program has been updated to work
2440with previously made API name changes.
2441
2442The ext2fs_free() command now uses the new badblocks API to avoid
2443using the compatibility layer.
2444
2445Added new regression test cases; the run_e2fsck test script now
2446supports the ability for a test case to run a prepratory command
2447before running e2fsck.
2448
Theodore Ts'o28e11941999-10-26 18:17:20 +00002449E2fsprogs 1.17 (October 26, 1999)
2450=================================
2451
2452Fixed nasty typo in fsck which caused parallelized fsck's to go into an
2453infinite loop.
2454
2455Fixed a bug in fsck where it used strncmp to compare a binary UUID,
2456thus potentially causing problems if a binary UUID contained a NULL
2457character.
2458
2459E2fsck now uses stricter checks for directory entries in pass 2:
2460zero-length filenames are not allowed; neither are 8 byte long
2461directory entries.
2462
2463The debugfs "dirty" command now clears the filesystem valid bit.
2464(Previously this just set the dirty-as-in-needs-writing-out-to-disk
2465bit in the in-core superblock image. The new functionality is more
2466what the user expects, and is more useful.)
2467
2468Added a debugging hook to test parallel fsck; if the environment
2469variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
2470will be checked in parallel when they normally would not be.
2471
2472Programmer's notes:
2473-------------------
2474
2475Fixed some #ifdef's for compilation under the Hurd OS.
2476
2477Fixed minor W2K compatibility problems.
2478
2479Fixed some miscellaneous GCC warnings.
2480
2481
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00002482E2fsprogs 1.16 (October 22, 1999)
2483=================================
2484
2485Fixed a race condition bug in fsck; when printing a progress bar, if
2486checking multiple filesystems in parallel, it was possible for fsck to
2487send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
2488handler, which would cause it to terminate with a signal 10.
2489
2490E2fsck now properly handles filesystems that have the
2491INCOMPAT_FILETYPE feature turned on. It can be used to convert a
2492filesystem into using or not using FILETYPE feature.
2493
2494E2fsck now properly handles filesystems that have the IMAGIC feature
2495turned on (this is used on Linux AFS servers).
2496
2497The mke2fs program now creates filesystems that have the filetype and
2498sparse_superblock features enabled by default, unless it is run on a
2499pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
2500so there is now a new flag -O which allows the user to specify with
2501which features she would like to create the filesystem; "mke2fs -O
2502none" will create a filesystsem compatible with 2.0 kernels.
2503
2504The tune2fs program now has a -O option which allows the user to set
2505and reset "safe" filesystem features. Currently, the only ones which
2506allows to be modified are the filetype and sparse_superblock features.
2507Note setting or clearing either feature will require running e2fsck on
2508the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
2509requires that there is enough free space on the filesystem for the
2510extra superblocks which will be created by e2fsck.)
2511
2512Debugfs can now set and print filesystem features in the superblock
2513using the "features" command. Dumpe2fs will print out the complete
2514set of features when listing the superblock.
2515
2516Dumpe2fs has new options -f (force) and -h (header-only).
2517
2518Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
2519message to come up. This could happen when decrementing or
2520incrementing a link count could result in an overflow.
2521
2522Fixed a bug in e2fsck where the block count on the lost+found
2523directory would not be properly incremented when the directory was
2524expanded to the point where an indirect block needed to be allocated.
2525
2526E2fsck now makes some additional sanity checks on the superblock to
2527avoid crashing or giving a memory allocation error if some of the
2528values in the superblock are unresonable (but the superblock otherwise
2529looks valid).
2530
2531Fixed a bug in e2fsck where a very badly corrupted filesystem might
2532require two passes to completely fix the filesystem. This happened if
2533an inode claimed blocks that was part of the filesystem metadata
2534(typically, when garbage was written into an inode table or indirect
2535block, since this kind of filesystem corruption normally doesn't
2536happen otherwise).
2537
2538On the Alpha, glibc declares st_flags although it isn't actually used;
2539the configure script was improved to detect this case so that
2540e2fsprogs can avoid using the non-functional stat field.
2541
2542The manual pages were updated to use a more consistent formatting
2543style consistent with standard Unix man pages. Mke2fs's man page
2544added documentation for a few previously undocumented options.
2545
2546Fixed minor display bugs in tune2fs and mke2fs.
2547
2548Programmer's notes:
2549-------------------
2550
2551Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
2552
2553Added features to parse and print feature strings into the e2p library.
2554(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
2555
2556ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
2557whose directory entries contain proper filetype information if the
2558filesystem supports it.
2559
2560ext2fs_link() now uses the low 3 bits of its flags parameter to pass
2561the directory entry filetype information. This is used to set the
2562directory entry filetype information if the filesystem supports it.
2563
2564Fixed a bug in ext2fs_expand_dir() where the block count in a
2565directory's inode would not be properly incremented when the directory
2566was expanded to the point where an indirect block needed to be
2567allocated.
2568
2569
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002570E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002571==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002572
2573Add configuration checks so that e2fsprogs will compile cleanly on
2574Linux 2.3 kernels that have renamed i_version to i_generation.
2575
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002576E2fsck now prints a progress/completion bar (and not just a simple
2577spinner) if the -C0 option is requested or if it receives a SIGUSR1
2578signal. Fsck will automatically manage the (potentially muliple)
2579e2fsck processes to print completion bars if it is given a -C option,
2580with the right thing happening if multiple filesystems are being
2581checked in parallel.
2582
2583Mke2fs now has better automatic hueristics to determine the filesystem
2584parameters to be used for a particular filesystem. Added a new option
2585-T which allows the user to specify how the filesystem is to be used,
2586which helps mke2fs do a better job selecting the filesystem parameters.
2587
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002588Mke2fs now creates revision 1 filesystems by default, and with the
2589sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00002590not understood by Linux 2.0 kernels, so they will only allow read-only
2591mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002592
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002593Fix bug where if /dev/null couldn't be opened (should never happen),
2594e2fsck would hang in a tight loop.
2595
2596Make e2fsck handle the case where /lost+found isn't a directory.
2597
2598E2fsck now uses mallinfo if it exists to get accurate statistics about
2599its memory usage.
2600
2601Fix bug in e2fsck where it wouldn't check to see if a disconnected
2602inode had any problems before connecting it to /lost+found.
2603
2604Add check to e2fsck so it makes sure that total number of inodes in
2605the filesystem is a sane number.
2606
2607Fix fencepost error when clearing an the end of the block bitmap which
2608caused the last block in the bitmap not to get cleared.
2609
2610Cleaned up a number of messages in e2fsck:
2611 * The message "Group's #'s copy of the group descriptor..."
2612 was fixed so that the correct number would be displayed.
2613 * Added missing space in the "disk write-protected" error messsage
2614 * Cleaned up the error message printed when a non-interactive
2615 e2fsck needs to abort a check because the filesystem
2616 appears to be mounted.
2617
2618Added a new command-line utility, uuidgen, which will create and print
2619a UUID.
2620
2621Make debugfs's icheck command more robust by checking to make sure an
2622inode has valid blocks before interarting over the inode's blocks.
2623
2624UUID generation now uses a random-based scheme whenever possible to
2625prevent potential privacy problems.
2626
2627Man pages for all of the UUID functions in the lirbary were added.
2628
2629Fixed bug in fsck so it won't coredump if a filesystem not in
2630/etc/fstab is given to it.
2631
2632Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
2633that most of the other mount utilities understands.
2634
2635Mke2fs will make a filesystem even if it appears mounted if the force
2636option is given.
2637
2638Dumpe2fs has new command-line options which allow a filesystem expert
2639to specify the superblock and blocksize when opening a filesystem.
2640This is mainly useful when examining the remains of a toasted
2641filesystem.
2642
2643The badblocks program has been updated to display correctly on disks
2644with large block numbers.
2645
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002646The badblocks program no longer gives spurious errors when errors
2647occur on non-block boundaries, which is common if the blocksize is
2648larger than 1k.
2649
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002650Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
2651MKE2FS_SYNC environment variable is set. This is to work around a VM
2652bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002653to trigger it even using a 2.2 kernel, but hopefully it will not be
2654needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002655
2656Fixed miscellaneous documentation and man pages.
2657
2658Programmer's notes:
2659-------------------
2660
2661Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
2662in e2fsck's pass1.c really should have been static.
2663
2664The return value of the uuid_compare() function was changed to make it
2665match with the convetions used by strcmp, memcmp, and Paul Leach's
2666UUID sample document.
2667
2668The "make depend" process has now been made more automated; it now
2669automatically word-wraps the dependencies, and only replaces source
2670Makefile.in if there has been a change in the dependencies. Also, a
2671top-level "make depend" now recurses through all the subdirectories
2672automatically.
2673
2674The Makefile in .../util has been changed so that subst is built using
2675the native C compiler during a cross-compilation, since the subst
2676program is only used during the build process. Also add an explicit
2677rule to build util/subst by cd'ing to the correct directory and
2678running Makefile.
2679
2680The man directories are defined in terms mandir, so that the configure
2681script can override the location of the manual pages.
2682
2683The config files have been updated to recognize new machine types for
2684both the i386 and alpha families.
2685
2686Fsck has been modified so that it will accurately create an
2687fsck_instance even when the noexecute flag is set. This allows for
2688accurate debugging of the fsck pass structure. Also, when the verbose
2689flag is given twice, fsck will print debugging information about when
2690fsck is waiting for jobs to finish.
2691
2692
Theodore Ts'o14790ed1999-01-12 23:32:52 +00002693E2fsprogs 1.14 (January 9, 1999)
2694================================
2695
2696Fix the fstab parsing code so that it can handle blank lines and
2697comment characters. Also, missing pass numbers need to be treated as
2698zero.
2699
2700Fixed a bug in e2fsck where under some circumstances (when e2fsck
2701needs to restart processing after fixing an egregious inconsistency)
2702it would try to access already freed memory.
2703
2704E2fsck now prints non-printable characters in directory entries and
2705pathnames using '^' and 'M-' notation.
2706
2707Fixed chattr so that it will ignore symbolic links when doing
2708recursive descent traversals. For both chattr and lsattr, no longer
2709print the version string unless the -V option is given.
2710
2711Allow the system administrator to directly specify the number of
2712inodes desired in the filesystem, for some special cases where this is
2713necessary.
2714
2715Fix portability problems so that e2fsprogs can be compiled under Linux
27161.2 systems and Solaris systems.
2717
2718Update the config.guess file with a more recent version that will
2719identify newer Linux platforms.
2720
2721Programmer's notes
2722------------------
2723
2724Ext2fs_read_inode and ext2fs_write_inode will now return an error if
2725an inode number of zero is passed to them.
2726
Theodore Ts'o556ad131998-12-19 08:10:58 +00002727E2fsprogs 1.13 (December 15, 1998)
2728==================================
2729
2730Fixed a bug in debugfs where an error messages weren't getting printed
2731when the ext2 library routines to read inodes returned errors in the
2732stat, cmri and rm commands.
2733
2734Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
2735provided, it won't create an inode table smaller than the minimum
2736number of inodes required for a proper ext2 filesystem.
2737
2738Fsck now parses the /etc/fstab file directly (instead of using
2739getmntent()), so that it can distinguish between a missing pass number
2740field and pass number field of zero. This caused problems for
2741diskless workstations where all of the filesystems in /etc/fstab have
2742an explicit pass number of zero, and fsck could not distinguish this
2743from a /etc/fstab file with missing pass numbers.
2744
2745E2fsck will create a /lost+found directory if there isn't one in the
2746filesystem, since it's safer to create the lost+found directory before
2747it's needed.
2748
2749Fixed e2fsck so that it would detect bogus immutable inodes which
2750happen to be sockets and FIFO files, and offer to clear them.
2751
2752If a filesystem has multiple reasons why it needs to be checked, and
2753one of the reasons is that it is uncleanly mounted, e2fsck will print
2754that as the reason why the filesystem is being checked.
2755
2756Cleaned up the output routines of mke2fs so that it doesn't overflow
2757an 80 column display when formating really big filesystems.
2758
2759Added a sanity check to e2fsck to make sure that file descriptors 0,
27601, 2 are open before opening the hard disk. This avoids a problem
2761where a broken program might exec e2fsck with those file descriptors
2762closed, which would cause disastrous results if the kernel returns a
2763file descriptor for the block device which is also used by FILE *
2764stdout.
2765
2766Fixed up the e2fsck progress reporting functions so that the values
2767reliably reach 100% at the completion of all of the e2fsck passes.
2768
2769Fixed minor documentation bugs in man pages and usage messages.
2770
2771Programmer's notes:
2772-------------------
2773
2774Fixed a number of lint warnings in the ext2fs library and potential
2775portability problems from other OS's header files that might define
2776CPP macros for names like "max" and "min".
2777
2778ext2fs_badblocks_list_add() has been made more efficient when it needs
2779to grow the bad blocks list.
2780
2781Fixed a bug in e2fsck which caused it to dereference a freed pointer
2782just before exiting.
2783
2784Fixed the substition process for generating the mk_cmds and compile_et
2785scripts so that they will work outside of the build tree.
2786
2787Add sanity check to e2fsck so that if an internal routine
2788(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
2789and causing a core dump. This should never happen, but...
2790
Theodore Ts'oa5696711998-07-09 05:38:07 +00002791E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00002792==================================
2793
2794E2fsprogs now works with glibc (at least with the version shipped wtih
2795RedHat 5.0). The ext2fs_llseek() function should now work even with
2796i386 ELF shared libraries and if llseek() is not present. We also
2797explicitly do a configure test to see if (a) llseek is in libc, and
2798(b) if llseek is declared in the system header files. (See standard
2799complaints about libc developers don't understand the concept of
2800compatibility with previous versions of libc.)
2801
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002802The ext2fs library now writes out the block group number in each of
2803the superblock copies. This makes it easier to automatically
2804determine the starting block group of the filesystem when the block
2805group information is trashed.
2806
2807Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00002808which means that e2fsprogs will ignore the high 8 bits of the
2809directory entry's name_len field, so that it can be used for other
2810purposes.
2811
2812Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
2813E2fsprogs will now support filesystems with 64-bit sized files.
2814
2815Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
2816
Theodore Ts'o21d53851998-02-21 03:14:50 +00002817Added new program "e2label", contributed by Andries Brouwer. E2label
2818provides an easy-to-use interface to modify the filesystem label.
2819
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002820Fixed bug so that lsattr -v works instead of producing a core dump.
2821
Theodore Ts'o21d53851998-02-21 03:14:50 +00002822Fixed a minor bug in mke2fs so that all groups with bad superblock
2823backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002824
2825Mke2fs will check the size of the device, and if the user specifies a
2826filesystem size larger than the apparent size of the device it will
2827print a warning message and ask if the user wants to proceed.
2828
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002829E2fsck has a new option -C, which sends completion information to the
2830specified file descriptor. For the most part, this is intended for
2831programs to use, although -C 0 will print a spinning character to the
2832stdout device, which may be useful for users who want to see something
2833happening while e2fsck goes about its business.
2834
Theodore Ts'o21d53851998-02-21 03:14:50 +00002835Fixed a bug in e2fsck which could cause a core dump when it needs to
2836expand the /lost+found directory, and sometimes the bitmaps haven't
2837been merged in. Also fixed a related bug where ext2fs_write_dir_block
2838was used to write out a non-directory block. (Which would be bad on a
2839non-Intel platform with byte swapping going on.)
2840
2841Fixed bug in e2fsck where it would print a "programming error" message
2842instead of correctly identifying where a bad block was in used when
2843the bad block was in a non-primary superblock or block group
2844descriptor. Also fixed a related bug when sparse superblocks are in
2845use and there is a bad block where a superblock or block group
2846descriptor would have been in a group that doesn't include a
2847superblock.
2848
2849Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
2850the block group descriptor table is corrupt, it was possible to try to
2851allocate a huge array, fail, and then abort e2fsck.
2852ext2fs_get_num_dirs() now sanity checks the block group descriptor,
2853and subsitutes reasonable values if the descriptors are obviously bogus.
2854
2855If e2fsck finds a device file which has the immutable flag set and the
2856i_blocks beyond the normal device number are non-zero, e2fsck will
2857offer to remove it, since it's probably caused by garbage in the inode
2858table.
2859
2860When opening a filesystem, e2fsck specially checks for the EROFS error
2861code, and prints a specific error message to the user which is more
2862user friendly.
2863
2864If the filesystem revision is too high, change the e2fsck to print
2865that this is either because e2fsck is out of date, or because the
2866superblock is corrupt.
2867
2868E2fsck now checks for directories that have duplicate '.' and '..'
2869entries, and fixes this corruption.
2870
2871E2fsck no longer forces a sync of the filesystem (with attendant sleep
2872calls) at all times. The ext2fs_flush() function now performs a sync
2873only if it needed to write data blocks to disk.
2874
2875Fixed a minor bug in e2fsck's pass1b's file cloning function, where
2876certain errors would not be properly reported.
2877
2878Updated and expanded a few points in the man pages which users
2879complained wheren't explicit enough.
2880
2881Added special case byte-swapping code if compiling on the PowerPC, to
2882accomodate the strange big-endian variant of the ext2 filesystem that
2883was previously used on the PowerPC port.
2884
2885
2886Programmer's notes:
2887-------------------
2888
2889Removed C++ keywords from the ext2fs libraries so that it could be
2890compiled with C++.
2891
2892E2fsck's internal organization has now been massively reorganized so
2893that pass*.c don't have any printf statements. Instead, all problems
2894are reported through the fix_problem() abstraction interface. E2fsck
2895has also been revamped so that it can be called as a library from a
2896application.
2897
2898Added new fileio primitives in libext2fs for reading and writing
2899files on an unmounted ext2 filesystem. This interface is now used by
2900debugfs.
2901
2902Added a new libext2fs function for mapping logical block numbers of
2903a file to a physical block number.
2904
2905Added a new libext2fs function, ext2fs_alloc_block(), which allocates
2906a block, zeros it, and updates the filesystem accounting records
2907appropriately.
2908
2909Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
2910sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
2911
2912The libext2fs functions now use a set of memory allocation wrapper
2913functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
2914instead of malloc, free, and resize. This makes it easier for us to
2915be ported to strange environments where malloc, et. al. aren't
2916necessarily available.
2917
2918Change the libext2fs fucntion to return ext2-specific error codes
2919(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
2920and depending on the existence of system error codes (such as EEXIST
2921and ENOENT).
2922
2923Renamed io.h to ext2_io.h to avoid collision with other OS's header
2924files.
2925
2926Add protection against ext2_io.h and ext2fs.h being included multiple
2927times.
2928
2929The types used for memory lengths, etc. have been made more portable.
2930In generla, the code has been made 16-bit safe. Added Mark
2931Habersack's contributed DOS disk i/o routines.
2932
2933Miscellaneous portability fixes, including not depending on char's
2934being signed.
2935
2936The io_channel structure has a new element, app_data, which is
2937initialized by the ext2fs routines to contain a copy of the filesystem
2938handle.
2939
2940ext2fs_check_directory()'s callback function may now return the error
2941EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
2942really do the checking, despite the presence of the callback function.
2943

Theodore Ts'obc210071997-06-17 05:41:36 +00002945E2fsprosg 1.11 (June 17, 1997)
2946==============================
2947
2948Fixed e2fsck to detect (previously ignored) conflicts between the
2949superblock or block group descriptors and block bitmaps, inode
2950bitmaps, and inode tables.
2951
2952Fixed bug in e2fsck so that when the message printed out when a block
2953or inode bitmap conflicts with other data, it has the correct group
2954number.
2955
2956Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
2957to badblocks. This meant that not all of the filesystem was being
2958tested for bad blocks!
2959
2960Fixed an array boundary overrun case which cropped up in
2961ext2fs_badblocks_list_test when a user tried running "mke2fs -c
2962-b 4096".
2963
2964Adjusted the number of columns printed by mke2fs when displaying the
2965superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00002966really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00002967
2968Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
2969dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
2970fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
2971
2972Programmer's notes:
2973-------------------
2974
2975Fixed install rule in lib/ss so that ss_err.h is actually getting
2976installed.
2977
2978Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
2979bassed back to the caller.
2980
2981Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
2982setting the current inode number (which meant this function wasn't
2983working at all).
2984
2985Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
2986blocks in the bitmap when increasing the size of the bitmap.
2987
2988Changed the initial number of blocks allocated by ext2fs_init_dblist()
2989to be more realistic.
2990
2991Added a new function ext2fs_allocate_group_table, which sets up the
2992group descriptor information (and allocates inode and block bitmaps,
2993and inode tables for a particular group). The function was created by
2994factoring out code form ext2fs_allocate_tables().
2995
2996Added a new function ext2fs_move_blocks which takes a bitmap of the
2997blocks to be moved, and moves them to another location on the
2998boardboard.
2999
3000Make the unix_io channel's io_channel_flush implementation calls sync()
3001to to flush the kernel buffers to disk.
3002
3003Added a new function ext2fs_dblist_count returns the number of
3004directory blocks in dblist.
3005
3006
Theodore Ts'oae851481997-04-29 18:13:24 +00003007E2fsprogs 1.10 (April 24, 1997)
3008===============================
3009
3010Mke2fs once again defaults to creating revision #0 filesystems, since
3011people were complaining about breaking compatibility with 1.2 kernels.
3012Warning messages were added to the mke2fs and tune2fs man pages that
3013the sparse superblock option isn't supported by most kernels yet (1.2
3014and 2.0 both don't support parse superblocks.)
3015
3016Added new flag to mke2fs, -R <raid options>, which allows the user to
3017tell mke2fs about the RAID configuration of the filesystem. Currently
3018the only supported raid option is "stride" which specifies the width
3019of the RAID stripe.
3020
3021Fixed bug in e2fsck where pass1b would bomb out if there were any
3022blocks marked bad in the inode table.
3023
3024Fixed rare bug in mke2fs where if the user had a very unlucky number
3025of blocks in a filesystem (probability less than .002) the resulting
3026filesystem would be corrupt in the last block group.
3027
3028Fixed bug where if e2fsck tried to allocate a block to fix a
3029filesystem corruption problem and the filesystem had no free blocks,
3030ext2fs_new_block() would loop forever.
3031
3032The configure script now checks explicitly to see if "-static" works,
3033since that can't be assumed to be true --- RedHat doesn't install
3034libc-static by default.
3035
3036Fixed bug in libext2's block iterator functions where under some
3037cirmcustances, file with holes would cause the bcount parameter to the
3038callback function to be incorrect. This bug didn't affect any of
3039e2fsprogs programs, but it was discovered by Paul Mackerras, the
3040author of the PPC boot loader.
3041
3042Removed use of static variables to store the inode cache in libext2fs.
3043This caused problems if more than one filesystem was accessed via
3044libext2fs (static variables in libraries are generally a bad idea).
3045Again, this didn't affect e2fsprogs programs, but it was discovered by
3046Paul Mackerras.
3047
3048Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
3049will compile cleanly with 1.2.13 kernels (even with a.out shared
3050libraries!)
3051
3052Programmer's notes:
3053-------------------
3054
3055Added new functions to duplicate an ext2 filesystem handle, and its
3056associated substructure. New functions: ext2fs_dup_handle(),
3057ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
3058Other structures, such as the io_channel and the inode_cache, now have
3059a ref count so that they only get freed when they are no longer used
3060by any filesystem handle. (These functions were added as part of the
3061development effort for an ext2 resizer).
3062
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00003063E2fsprogs 1.09 (April 14, 1997)
3064===============================
3065
3066Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
3067accidentally introduced in the 1.08 release. The overhead calculation
3068was accidentally removed, which caused ext2fs_initialize() to not
3069notice when the filesystem size needed to be adjusted down because
3070there wasn't enough space in the last block group.
3071
3072Fixed bug in version parsing library routine; it was always parsing
3073the library version string, instead of using the passed-in string.
3074
3075Clarified chattr man page.
3076
Theodore Ts'o24757fa1997-04-29 17:39:27 +00003077E2fsprogs 1.08 (April 10, 1997)
3078===============================
3079
3080E2fsck 1.07 was very slow when checking very large filesystems with a
3081lot of files that had hard links (i.e., news spools). This was fixed
3082by seriously revamping the icount abstraction. Added a formal test
3083suite for the icount abstraction.
3084
3085Debugfs now has a "-l" option to the "ls" command, which lists the
3086inode number, permissions, owner, group, size, and name of the files
3087in the directory.
3088
3089Fix a bug in e2fsck where when a directory had its blocks moved to
3090another location during the pass 1b processing, the directory block
3091list wasn't updated, so pass 2 wouldn't check (and correct) the
3092correct directory block.
3093
3094E2fsck will now treat inodes which contain blocks which are claimed by
3095the filesystem metadata by treating them as multiply claimed blocks.
3096This way, the data in those blocks can be copied to a new block during
3097the pass 1b--1d processing.
3098
3099E2fsck will attempt to determine the correct superblock number and
3100display it in the diagnostic and warning messages if possible.
3101
3102Add support for a new (incompatible) feature, "sparse_super". This
3103feature reduces the number of blocks which contain copies of backup
3104superblocks and block group descriptors. (It is only an incompatible
3105feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
3106support a new -s option; e2fsck will recognize filesystems built with
3107this feature turned on.
3108
3109E2fsck now checks the library to make sure is the correct version,
3110using new library functions. (This helps to diagnose incorrectly
3111installed e2fsprogs distributions.)
3112
3113Dumpe2fs now prints more information; its now prints the the
3114filesystem revision number, the filesystem sparse_super feature (if
3115present), the block ranges for each block group, and the offset from
3116the beginning of the block group.
3117
3118Mke2fs now distributes the inode and block bitmap blok so that the
3119won't be concentrated in one or two disks in RAID/striping setups.
3120Also, if the user chooses a 2k or 4k block group, mke2fs will try to
3121choose the largest blocks per group that be chosen. (For 2k blocks,
3122you can have up to 16384 blocks/group; for 4k blocks, you can have up
3123to 32768 blocks/group.) Previously mke2fs would not allow
3124specification of more than 8192 blocks per group, even if you were
3125using a 2k or 4k block group.
3126
3127Programmer's notes:
3128-------------------
3129
3130Added a new function ext2fs_create_icount2() which takes a "hint"
3131argument. This hint argument presets the icount array with the list
3132of inodes which actually need to be in the icount array. This really
3133helps to speed up e2fsck.
3134
3135Added a new function ext2fs_icount_validate() which checks the rep
3136invariant for the icount structure. This is used mostly for testing.
3137
3138The error mesasage given when a bad inode number is passed to
3139test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
3140EXT2FS_UNMARK_ERROR).
3141
3142Added a new function ext2fs_set_dir_block which sets the block of a
3143dblist entry, given the directory inode and blockcnt.
3144
3145Added a new function ext2fs_get_library_version() which returns the
3146current library version, and ext2fs_parse_version_string() which
3147returns a version number based on a e2fsprogs version string.
3148
3149The icount functions will return EINVAL if the passed in inode number
3150is out of bounds.
3151
Theodore Ts'o21c84b71997-04-29 16:15:03 +00003152E2fsprogs 1.07 (March 9, 1997)
3153==============================
3154
3155E2fsck is now uses much less memory when checking really large
3156filesystems (or rather, filesystems with a large number of inodes).
3157Previously a filesystem with 1 million inodes required 4 megabytes of
3158memory to store inode count statistics; that storage requirement has
3159now been reduced to roughly half a megabyte.
3160
3161E2fsck can now properly deal with bad blocks appearing inside the
3162inode table. Instead of trying to relocate the inode table (which
3163often failed because there wasn't enough space), the inodes in the bad
3164block are marked as in use.
3165
3166E2fsck will automatically try to use the backup superblocks if the
3167primary superblocks have a bad magic number or have missing meta-data
3168blocks (or meta-data blocks which are out of range).
3169
3170E2fsck's pass 3 has been made more efficient; most noticeable on
3171filesystems with a very large number of directories.
3172
3173Completely revamped e2fsck's system of printing problem reports. It
3174is now table driven, to make them more easily customizeable and
3175extendable. Error messages which can be printed out during preen mode
3176are now one line long.
3177
3178Fixed e2fsck's filesystem swapping code so that it won't try to swap
3179fast symbolic links or deleted files.
3180
3181Fixed e2fsck core dumping when fixing a filesystem which has no
3182directories (not even a root directory).
3183
3184Added a check to e2fsck to make sure that the length of every
3185directory entry is a multiple of 4 (since the kernel complains if it
3186isn't).
3187
3188Added a check to e2fsck to make sure that a directory entry isn't a
3189link to the root directory, since that isn't allowed.
3190
3191Added a check to e2fsk to now make sure the '.' and '..' directory
3192entries are null terminated, since the 2.0 kernel requires it.
3193
3194Added check to write_bitmaps() to make sure the superblock doesn't get
3195trashed if the inode or block bitmap is marked as being block zero.
3196
3197Added checking of the new feature set fields in the superblock, to
3198avoid dealing with new filesystem features that this package wasn't
3199set up to handle.
3200
3201Fixed a fencepost error in ext2fs_new_block() which would occasionally
3202try to allocate a block beyond the end of a filesystem.
3203
3204When the UUID library picks a random IEEE 802 address (because it
3205can't find one from a network card), it sets the multicast bit, to
3206avoid conflicting with a legitimate IEEE 802 address.
3207
3208Mke2fs now sets the root directory's owner to be the real uid of the
3209user running mke2fs. If the real uid is non-zero, it also sets
3210the group ownership of the root directory to be the real group-id of
3211the user running mke2fs.
3212
3213Mke2fs now has more intelligent error checking when it is given a
3214non-existent device.
3215
3216When badblocks is given the -vv option, it now updates the block that
3217it is currently testing on every block.
3218
3219Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
3220currently correctly if PATH wasn't already set.
3221
3222Shared libraries now built with dependencies. This allows the shared
3223library files to be used with dlopen(); it also makes the transition
3224to libc 6 easier, since ld.so can tell which libc a particular shared
3225library expects to use.
3226
3227Programmer's notes:
3228-------------------
3229
3230Added new abstraction (defined in dblist.c) for maintaining a list of
3231blocks which belongs to directories. This is used in e2fsck and other
3232programs which need to iterate over all directories.
3233
3234Added new functions which test to see if a contiguous range of blocks
3235(or inodes) are available. (ext2fs_*_bitmap_range).
3236
3237Added new function (ext2_inode_has_valid_blocks) which returns true if
3238an inode has valid blocks. (moved from e2fsck code).
3239
3240Added new function (ext2fs_allocate_tables) which allocates the
3241meta-data blocks as part of initializing a filesystem. (moved from
3242mke2fs code).
3243
3244Added a new I/O manager for testing purposes. It will either allow a
3245program to intercept I/O requests, or print debugging messages to
3246trace the activity of a program using the I/O manager.
3247
3248The badblocks_list functions now store the bad blocks in a sorted
3249order, and use a binary search to speed up badblocks_list_test.
3250
3251The inode scan function ext2fs_get_next_inode() may now return a soft
3252error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
3253those cases where part of an inode table is missing or there is a bad
3254block in the inode table.
3255
3256Added a new function (ext2fs_block_iterate2) which adds new arguments to
3257the callback function to return a pointer (block and offset) to the
3258reference of the block.
3259
3260Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
3261application to jump to a particular block group while doing an inode
3262scan.
3263
3264The badblocks list functions were renamed from badblocks_* to
3265ext2fs_badblocks_*. Backwards compatibility functions are available
3266for now, but programs should be modified to use the new interface.
3267
3268Some of the library functions were reorganized into separate files to
3269reduce the size of some programs which statically link against the
3270ext2 library.
3271
3272Put in some miscellaneous fixes for the Alpha platform.
3273
Theodore Ts'o5c576471997-04-29 15:29:49 +00003274
3275E2fsprogs 1.06 (October 7, 1996)
3276================================
3277
3278Fixed serious bug in e2fsck: if the block descriptors are bad, don't
3279smash the backup copies in ext2fs_close(). (The problem was that when
3280e2fsck -p discovered the problem, while it was closing the filesystem
3281and exiting, it was also blowing away the backup superblocks on the
3282disk, which was less than friendly.) We now make it the case that we
3283only write out the backup superblock and the back block descriptors if
3284the filesystem is completely free from problems.
3285
3286Fixed a bug in block_interate in the lib/ext2fs library which caused
3287e2fsck to fail on GNU Hurd-created filesystems.
3288
3289Add support for Linux/FT's bootloader, which actually uses
3290EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
3291to clear the inode.
3292
3293Add support for the "A" (no atime update) attribute. (Note: this
3294attribute is not yet in production kernels.)
3295
3296The test suite is not automatically run when doing a "make all" from
3297the top level directory. Users should manually run "make check" if
3298they wish to run the test suite.
3299
3300Upon a preenhalt(), make the printed message more explicit that
3301running e2fsck "MANAULLY" means without the -p or -a options.
3302
3303In e2fsck, if a disconnected inode is zero-length, offer to clear it
3304instead of offering to connect it to lost+found.
3305
3306In e2fsck, if a filesystem was just unmounted uncleanly, and needs
3307e2fsck to be run over it, change e2fsck to explicitly display this
3308fact.
3309
3310For dumpe2fs and e2fsck, cause the -V option to print out which
3311version of the ext2fs library is actually getting used. (This will
3312help detect mismatches of using a 1.06 utility with a 1.05 library,
3313etc.)
3314
3315Programmers' notes:
3316-------------------
3317
3318EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
3319the naming convention.
3320
3321In ext2fs_initialize(), make sure the description for the inode bitmap
3322is correctly initialize.
3323
3324Fixed minor type typo in ext2fs_allocate_generic_bitmap();
3325
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00003326E2fsprogs 1.05 (September 7, 1996)
3327==================================
3328
3329Add support for new fields in the ext2 superblock --- volume name,
3330volume UUID, and last mounted field. Dumpe2fs displays these fields,
3331tune2fs and mke2fs allows you to set them. E2fsck will automatically
3332generate a UUID for those volumes that don't have them.
3333
3334Put in support for e2fsck to recognize HURD specific ext2 features ---
3335most notably, the translator block. The e2fsprogs tools will now use
3336the creator_os field in the superblock to correctly handle different
3337OS-specific variants of the ext2 filesystem.
3338
3339E2fsck now fixes inodes which have a the deletion time set, but which
3340have a non-zero i_link_count field by offering to clear the deletion
3341time. Previously e2fsck assumed that the inode was deleted (per 0.3c
3342ext2 kernel behavior) and offered to unlink the file.
3343
3344If e2fsck sets the clean bit, but nothing else, set the exit code
3345FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
3346set the filesystem valid bit when it was previously cleared. :-) This
3347was needed to make the HURD fsck driver happy.
3348
3349If the user refuses to attach an unattached inode, e2fsck will no
3350longer set the inode's link count. Otherwise, the inode would end up
3351getting marked as unused, which might cause loss of data later.
3352
3353Make the message issued by e2fsck when the superblock is corrupt less
3354confusing for users. It now mentions that another reason for the
3355"corrupt superblock" message might be that the partition might not be
3356an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
3357
3358Make the libext2 library more robuest so that e2fsck won't coredump on
3359an illegal superblock where the blocksize is zero. (f_crashdisk is
3360the test case).
3361
3362By default, create filesystems where the default checkinterval is 6
3363months (180 days). Linux servers can be robust enough that 20 reboots
3364can be a long, long time.
3365
3366Added configure flag --enable-old-bitops, which forces the bitops to
3367use the old (native) bitmask operations. By default on the sparc
3368platform, the standard ext2 bit ordering is now used.
3369
3370Added a new feature to e2fsck to byte-swap filesystems; this can be
3371used to convert old m68k filesystems to use the standard byte-order
3372storage for the superblock, inodes, and directory blocks. This
3373function is invoked by using the '-s' option to e2fsck.
3374
3375Debugfs's "dump" command has been enhanced so that it writes out the
3376exact size of the file so that the nulls at the end of the file are
3377eliminated. The command also accept a new "-p" option which will
3378attempt preserve to preserve the ownernship, permissions, and
3379file modification/access times.
3380
3381Debugfs has two new options, -f and -R. The -R option allows the user
3382to execute a single debugfs command from the command line. The -f
3383option allows the user to specify a "command file" containing debugfs
3384commands which will get executed.
3385
3386Dumpe2fs now pretty prints the check interval, instead of just
3387printing the check interval as a number of seconds.
3388
3389Fix bugs in debugfs: the params command when no filesystem is opened
3390no longer causes a core dump. It is now possible to unlink a file
3391when a pathame containing a '/' is specified.
3392
3393Tune2fs has a new -C option which sets the number of times the
3394filesystem has been mounted.
3395
3396Fix the chattr '-v' option so that it actually works. Chattr was
3397being buggy about the -v option parsing.
3398
3399Programmers' notes:
3400-------------------
3401
3402The directory lib/uuid contains a set of library routines to generate
3403DCE compatible UUIDs.
3404
3405Extended ext2fs_namei() to handle symbolic links. Added new function
3406ext2fs_nami_follow() which will follow last symbolic link in the case
3407where the pathname points to a sym link.
3408
3409The ext2fs_block_iterate function will now return the HURD translator
3410block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
3411iterator to return data blocks only. The ext2fs.h file now defines
3412constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
3413BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
3414count field of the iterator callback function.
3415
3416The test script driver now takes an optional second argument, which is
3417the test case to be run. This allows you to run a test case without
3418needing to run the entire test suite.
3419
3420On Linux ELF systems, install the .so files in the correct places
3421(/usr/lib). The .so files must be stored in the same directory as the
3422.a files.
3423
3424Fixed miscellaneous HURD compilation issues with header file being
3425included in the right order.
3426
3427Fixed debugfs so that it resets optind to zero, not one, since setting
3428optind to zero is more correct.

Theodore Ts'oa4d09611997-04-29 14:28:00 +00003431E2fsprogs 1.04 (May 16, 1996)
3432=============================
3433
3434First "official" (1.03 was a limited release only) to support building
3435e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
3436kernels).
3437
3438This package includes a RPM specs file, that it can be built using the
3439RedHat Package Manager.
3440
3441E2fsck now prints a hint that if there are lots of incorrectly located
3442inode bitmaps, block bitmaps, and inode table blocks, the user might
3443want to try using e2fsck -b 8193 first, to see if that fares any
3444better.
3445
3446For ext2 filesystem written with the hurd, debugfs will now print out
3447the translator field when printing an inode structure.
3448
3449Lots of miscellaneous linking/installation cleanups:
3450
3451 Libraries are now linked using a relative pathname, instead of
3452 relying on -L working correct. It doesn't, in many cases, including
3453 current versions of GNU ld. This guarantees that the build tree is
3454 linking with the right libraries, instead of the ones installed in
3455 /usr/lib.
3456
3457 Header files, man pages, and the et/ss shell scripts are now
3458 generated using a custom substitution script, instead of relying on
3459 the configure script. This prevents needless recompilation of
3460 files; in addition, the custom substitution script is much faster.
3461
3462 e2fsck may now be linked dynamically, by using the
3463 --enable-dynamic-e2fsck flag to configure. This is not recommended,
3464 since it increases e2fsck's dependence on other files, but some
3465 people need to save disk space, and other critical programs on their
3466 systems were being linked dynamically anyway.
3467
3468 Programs such as fsck which didn't need to be linked against
3469 libext2fs (or mke2fs which didn't need to be linked against libe2p)
3470 only link against libraries they actually need. Otherwise, those
3471 programs would require the presense of libraries that otherwise
3472 could be removed from a rescuse diskette.
3473
3474 The ss include files are now installed correctly so they can
3475 actually be used by another package.
3476
3477 If the profiling libraries are built, they are now installed on a
3478 "make install-libs".

Theodore Ts'o7f88b041997-04-26 14:48:50 +00003481E2fsprogs 1.03 (March 27, 1996)
3482===============================
3483
3484Change the m68k bit numbering for bitmasks to match the bit numbering
3485used by all other ext2 implementations. (This change was requested by
3486the m68k kernel development team.)
3487
3488Support (in-development) filesystem format revision which supports
3489(among other things) dynamically sized inodes.
3490
3491Fixed a bug in the ext2 library so that an intelligent error is
3492returned if mke2fs is run with a ridiculously small number of blocks
3493for a partition.
3494
3495Fixed a bug in the ext2 library which required that the device be
3496openable in read/write mode in order to determine its size. This
3497caused e2fsck -n to require read/write access when it was not
3498previously necessary.
3499
3500Fixed a bug in e2fsck which casued it to occasionally fail the test
3501suite depending on which version of the floating point library it was
3502using.
3503
3504Fixed a bug in e2fsck so that it now halts with a fatal error when
3505certain superblock consistency checks fail. Previously it continued
3506running e2fsck, with some potential confusing/damaging consequences.
3507
3508Added new flag to fsck which allows the root to be checked in parallel
3509with other filesytems. This is not the safest thing in the world to
3510do, but some system administrators really wanted it.
3511
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00003512Fixed -Wall flames in lib/ss.
3513
Theodore Ts'o74becf31997-04-26 14:37:06 +00003514
3515E2fsprogs 1.02 (January 16, 1996)
3516=================================
3517
3518Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
3519
3520Change e2fsck to print statistics of how many non-contiguous files are
3521on the system. Note that a file which is larger than 8k blocks, it is
3522guaranteed to be non-contiguous.
3523
3524In mke2fs, print a warning message if a user tries to format a whole
3525disk (/dev/hda versus /dev/hda1). If a user really wants to format a
3526whole disk, the -F (force) option forces mke2fs to format a whole disk
3527as a filesytem.
3528
3529Fix a bug in fsck where in some cases it might start checking
3530partitions in the next pass before it finishes checking partitions in
3531the current pass. This still won't cause two partitions on the same
3532disk will be checked, so it's rarely a problem in real life.
3533
3534Patch lsattr so that it won't hang when checking a named pipe.
3535
3536Minor compilation fixes:
3537 * Fix the order of libraries that were linked in debugfs.
3538 * Allow the sources to be compiled with -ansi turned on.
