Theodore Ts'o21d53851998-02-21 03:14:50 +00001E2fsprogs 1.12 (February 20, 1998)
2==================================
3
4E2fsprogs now works with glibc (at least with the version shipped wtih
5RedHat 5.0). The ext2fs_llseek() function should now work even with
6i386 ELF shared libraries and if llseek() is not present. We also
7explicitly do a configure test to see if (a) llseek is in libc, and
8(b) if llseek is declared in the system header files. (See standard
9complaints about libc developers don't understand the concept of
10compatibility with previous versions of libc.)
11
12Added new program "e2label", contributed by Andries Brouwer. E2label
13provides an easy-to-use interface to modify the filesystem label.
14
15Fixed a minor bug in mke2fs so that all groups with bad superblock
16backup blocks are printed (not just the first one).
17
18Fixed a bug in e2fsck which could cause a core dump when it needs to
19expand the /lost+found directory, and sometimes the bitmaps haven't
20been merged in. Also fixed a related bug where ext2fs_write_dir_block
21was used to write out a non-directory block. (Which would be bad on a
22non-Intel platform with byte swapping going on.)
23
24Fixed bug in e2fsck where it would print a "programming error" message
25instead of correctly identifying where a bad block was in used when
26the bad block was in a non-primary superblock or block group
27descriptor. Also fixed a related bug when sparse superblocks are in
28use and there is a bad block where a superblock or block group
29descriptor would have been in a group that doesn't include a
30superblock.
31
32Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
33the block group descriptor table is corrupt, it was possible to try to
34allocate a huge array, fail, and then abort e2fsck.
35ext2fs_get_num_dirs() now sanity checks the block group descriptor,
36and subsitutes reasonable values if the descriptors are obviously bogus.
37
38If e2fsck finds a device file which has the immutable flag set and the
39i_blocks beyond the normal device number are non-zero, e2fsck will
40offer to remove it, since it's probably caused by garbage in the inode
41table.
42
43When opening a filesystem, e2fsck specially checks for the EROFS error
44code, and prints a specific error message to the user which is more
45user friendly.
46
47If the filesystem revision is too high, change the e2fsck to print
48that this is either because e2fsck is out of date, or because the
49superblock is corrupt.
50
51E2fsck now checks for directories that have duplicate '.' and '..'
52entries, and fixes this corruption.
53
54E2fsck no longer forces a sync of the filesystem (with attendant sleep
55calls) at all times. The ext2fs_flush() function now performs a sync
56only if it needed to write data blocks to disk.
57
58Fixed a minor bug in e2fsck's pass1b's file cloning function, where
59certain errors would not be properly reported.
60
61Updated and expanded a few points in the man pages which users
62complained wheren't explicit enough.
63
64Added special case byte-swapping code if compiling on the PowerPC, to
65accomodate the strange big-endian variant of the ext2 filesystem that
66was previously used on the PowerPC port.
67
68
69Programmer's notes:
70-------------------
71
72Removed C++ keywords from the ext2fs libraries so that it could be
73compiled with C++.
74
75E2fsck's internal organization has now been massively reorganized so
76that pass*.c don't have any printf statements. Instead, all problems
77are reported through the fix_problem() abstraction interface. E2fsck
78has also been revamped so that it can be called as a library from a
79application.
80
81Added new fileio primitives in libext2fs for reading and writing
82files on an unmounted ext2 filesystem. This interface is now used by
83debugfs.
84
85Added a new libext2fs function for mapping logical block numbers of
86a file to a physical block number.
87
88Added a new libext2fs function, ext2fs_alloc_block(), which allocates
89a block, zeros it, and updates the filesystem accounting records
90appropriately.
91
92Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
93sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
94
95The libext2fs functions now use a set of memory allocation wrapper
96functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
97instead of malloc, free, and resize. This makes it easier for us to
98be ported to strange environments where malloc, et. al. aren't
99necessarily available.
100
101Change the libext2fs fucntion to return ext2-specific error codes
102(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
103and depending on the existence of system error codes (such as EEXIST
104and ENOENT).
105
106Renamed io.h to ext2_io.h to avoid collision with other OS's header
107files.
108
109Add protection against ext2_io.h and ext2fs.h being included multiple
110times.
111
112The types used for memory lengths, etc. have been made more portable.
113In generla, the code has been made 16-bit safe. Added Mark
114Habersack's contributed DOS disk i/o routines.
115
116Miscellaneous portability fixes, including not depending on char's
117being signed.
118
119The io_channel structure has a new element, app_data, which is
120initialized by the ext2fs routines to contain a copy of the filesystem
121handle.
122
123ext2fs_check_directory()'s callback function may now return the error
124EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
125really do the checking, despite the presence of the callback function.
126

Theodore Ts'obc210071997-06-17 05:41:36 +0000128E2fsprosg 1.11 (June 17, 1997)
129==============================
130
131Fixed e2fsck to detect (previously ignored) conflicts between the
132superblock or block group descriptors and block bitmaps, inode
133bitmaps, and inode tables.
134
135Fixed bug in e2fsck so that when the message printed out when a block
136or inode bitmap conflicts with other data, it has the correct group
137number.
138
139Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
140to badblocks. This meant that not all of the filesystem was being
141tested for bad blocks!
142
143Fixed an array boundary overrun case which cropped up in
144ext2fs_badblocks_list_test when a user tried running "mke2fs -c
145-b 4096".
146
147Adjusted the number of columns printed by mke2fs when displaying the
148superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +0000149really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +0000150
151Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
152dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
153fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
154
155Programmer's notes:
156-------------------
157
158Fixed install rule in lib/ss so that ss_err.h is actually getting
159installed.
160
161Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
162bassed back to the caller.
163
164Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
165setting the current inode number (which meant this function wasn't
166working at all).
167
168Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
169blocks in the bitmap when increasing the size of the bitmap.
170
171Changed the initial number of blocks allocated by ext2fs_init_dblist()
172to be more realistic.
173
174Added a new function ext2fs_allocate_group_table, which sets up the
175group descriptor information (and allocates inode and block bitmaps,
176and inode tables for a particular group). The function was created by
177factoring out code form ext2fs_allocate_tables().
178
179Added a new function ext2fs_move_blocks which takes a bitmap of the
180blocks to be moved, and moves them to another location on the
181boardboard.
182
183Make the unix_io channel's io_channel_flush implementation calls sync()
184to to flush the kernel buffers to disk.
185
186Added a new function ext2fs_dblist_count returns the number of
187directory blocks in dblist.
188
189
Theodore Ts'oae851481997-04-29 18:13:24 +0000190E2fsprogs 1.10 (April 24, 1997)
191===============================
192
193Mke2fs once again defaults to creating revision #0 filesystems, since
194people were complaining about breaking compatibility with 1.2 kernels.
195Warning messages were added to the mke2fs and tune2fs man pages that
196the sparse superblock option isn't supported by most kernels yet (1.2
197and 2.0 both don't support parse superblocks.)
198
199Added new flag to mke2fs, -R <raid options>, which allows the user to
200tell mke2fs about the RAID configuration of the filesystem. Currently
201the only supported raid option is "stride" which specifies the width
202of the RAID stripe.
203
204Fixed bug in e2fsck where pass1b would bomb out if there were any
205blocks marked bad in the inode table.
206
207Fixed rare bug in mke2fs where if the user had a very unlucky number
208of blocks in a filesystem (probability less than .002) the resulting
209filesystem would be corrupt in the last block group.
210
211Fixed bug where if e2fsck tried to allocate a block to fix a
212filesystem corruption problem and the filesystem had no free blocks,
213ext2fs_new_block() would loop forever.
214
215The configure script now checks explicitly to see if "-static" works,
216since that can't be assumed to be true --- RedHat doesn't install
217libc-static by default.
218
219Fixed bug in libext2's block iterator functions where under some
220cirmcustances, file with holes would cause the bcount parameter to the
221callback function to be incorrect. This bug didn't affect any of
222e2fsprogs programs, but it was discovered by Paul Mackerras, the
223author of the PPC boot loader.
224
225Removed use of static variables to store the inode cache in libext2fs.
226This caused problems if more than one filesystem was accessed via
227libext2fs (static variables in libraries are generally a bad idea).
228Again, this didn't affect e2fsprogs programs, but it was discovered by
229Paul Mackerras.
230
231Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
232will compile cleanly with 1.2.13 kernels (even with a.out shared
233libraries!)
234
235Programmer's notes:
236-------------------
237
238Added new functions to duplicate an ext2 filesystem handle, and its
239associated substructure. New functions: ext2fs_dup_handle(),
240ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
241Other structures, such as the io_channel and the inode_cache, now have
242a ref count so that they only get freed when they are no longer used
243by any filesystem handle. (These functions were added as part of the
244development effort for an ext2 resizer).
245
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +0000246E2fsprogs 1.09 (April 14, 1997)
247===============================
248
249Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
250accidentally introduced in the 1.08 release. The overhead calculation
251was accidentally removed, which caused ext2fs_initialize() to not
252notice when the filesystem size needed to be adjusted down because
253there wasn't enough space in the last block group.
254
255Fixed bug in version parsing library routine; it was always parsing
256the library version string, instead of using the passed-in string.
257
258Clarified chattr man page.
259
Theodore Ts'o24757fa1997-04-29 17:39:27 +0000260E2fsprogs 1.08 (April 10, 1997)
261===============================
262
263E2fsck 1.07 was very slow when checking very large filesystems with a
264lot of files that had hard links (i.e., news spools). This was fixed
265by seriously revamping the icount abstraction. Added a formal test
266suite for the icount abstraction.
267
268Debugfs now has a "-l" option to the "ls" command, which lists the
269inode number, permissions, owner, group, size, and name of the files
270in the directory.
271
272Fix a bug in e2fsck where when a directory had its blocks moved to
273another location during the pass 1b processing, the directory block
274list wasn't updated, so pass 2 wouldn't check (and correct) the
275correct directory block.
276
277E2fsck will now treat inodes which contain blocks which are claimed by
278the filesystem metadata by treating them as multiply claimed blocks.
279This way, the data in those blocks can be copied to a new block during
280the pass 1b--1d processing.
281
282E2fsck will attempt to determine the correct superblock number and
283display it in the diagnostic and warning messages if possible.
284
285Add support for a new (incompatible) feature, "sparse_super". This
286feature reduces the number of blocks which contain copies of backup
287superblocks and block group descriptors. (It is only an incompatible
288feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
289support a new -s option; e2fsck will recognize filesystems built with
290this feature turned on.
291
292E2fsck now checks the library to make sure is the correct version,
293using new library functions. (This helps to diagnose incorrectly
294installed e2fsprogs distributions.)
295
296Dumpe2fs now prints more information; its now prints the the
297filesystem revision number, the filesystem sparse_super feature (if
298present), the block ranges for each block group, and the offset from
299the beginning of the block group.
300
301Mke2fs now distributes the inode and block bitmap blok so that the
302won't be concentrated in one or two disks in RAID/striping setups.
303Also, if the user chooses a 2k or 4k block group, mke2fs will try to
304choose the largest blocks per group that be chosen. (For 2k blocks,
305you can have up to 16384 blocks/group; for 4k blocks, you can have up
306to 32768 blocks/group.) Previously mke2fs would not allow
307specification of more than 8192 blocks per group, even if you were
308using a 2k or 4k block group.
309
310Programmer's notes:
311-------------------
312
313Added a new function ext2fs_create_icount2() which takes a "hint"
314argument. This hint argument presets the icount array with the list
315of inodes which actually need to be in the icount array. This really
316helps to speed up e2fsck.
317
318Added a new function ext2fs_icount_validate() which checks the rep
319invariant for the icount structure. This is used mostly for testing.
320
321The error mesasage given when a bad inode number is passed to
322test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
323EXT2FS_UNMARK_ERROR).
324
325Added a new function ext2fs_set_dir_block which sets the block of a
326dblist entry, given the directory inode and blockcnt.
327
328Added a new function ext2fs_get_library_version() which returns the
329current library version, and ext2fs_parse_version_string() which
330returns a version number based on a e2fsprogs version string.
331
332The icount functions will return EINVAL if the passed in inode number
333is out of bounds.
334
Theodore Ts'o21c84b71997-04-29 16:15:03 +0000335E2fsprogs 1.07 (March 9, 1997)
336==============================
337
338E2fsck is now uses much less memory when checking really large
339filesystems (or rather, filesystems with a large number of inodes).
340Previously a filesystem with 1 million inodes required 4 megabytes of
341memory to store inode count statistics; that storage requirement has
342now been reduced to roughly half a megabyte.
343
344E2fsck can now properly deal with bad blocks appearing inside the
345inode table. Instead of trying to relocate the inode table (which
346often failed because there wasn't enough space), the inodes in the bad
347block are marked as in use.
348
349E2fsck will automatically try to use the backup superblocks if the
350primary superblocks have a bad magic number or have missing meta-data
351blocks (or meta-data blocks which are out of range).
352
353E2fsck's pass 3 has been made more efficient; most noticeable on
354filesystems with a very large number of directories.
355
356Completely revamped e2fsck's system of printing problem reports. It
357is now table driven, to make them more easily customizeable and
358extendable. Error messages which can be printed out during preen mode
359are now one line long.
360
361Fixed e2fsck's filesystem swapping code so that it won't try to swap
362fast symbolic links or deleted files.
363
364Fixed e2fsck core dumping when fixing a filesystem which has no
365directories (not even a root directory).
366
367Added a check to e2fsck to make sure that the length of every
368directory entry is a multiple of 4 (since the kernel complains if it
369isn't).
370
371Added a check to e2fsck to make sure that a directory entry isn't a
372link to the root directory, since that isn't allowed.
373
374Added a check to e2fsk to now make sure the '.' and '..' directory
375entries are null terminated, since the 2.0 kernel requires it.
376
377Added check to write_bitmaps() to make sure the superblock doesn't get
378trashed if the inode or block bitmap is marked as being block zero.
379
380Added checking of the new feature set fields in the superblock, to
381avoid dealing with new filesystem features that this package wasn't
382set up to handle.
383
384Fixed a fencepost error in ext2fs_new_block() which would occasionally
385try to allocate a block beyond the end of a filesystem.
386
387When the UUID library picks a random IEEE 802 address (because it
388can't find one from a network card), it sets the multicast bit, to
389avoid conflicting with a legitimate IEEE 802 address.
390
391Mke2fs now sets the root directory's owner to be the real uid of the
392user running mke2fs. If the real uid is non-zero, it also sets
393the group ownership of the root directory to be the real group-id of
394the user running mke2fs.
395
396Mke2fs now has more intelligent error checking when it is given a
397non-existent device.
398
399When badblocks is given the -vv option, it now updates the block that
400it is currently testing on every block.
401
402Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
403currently correctly if PATH wasn't already set.
404
405Shared libraries now built with dependencies. This allows the shared
406library files to be used with dlopen(); it also makes the transition
407to libc 6 easier, since ld.so can tell which libc a particular shared
408library expects to use.
409
410Programmer's notes:
411-------------------
412
413Added new abstraction (defined in dblist.c) for maintaining a list of
414blocks which belongs to directories. This is used in e2fsck and other
415programs which need to iterate over all directories.
416
417Added new functions which test to see if a contiguous range of blocks
418(or inodes) are available. (ext2fs_*_bitmap_range).
419
420Added new function (ext2_inode_has_valid_blocks) which returns true if
421an inode has valid blocks. (moved from e2fsck code).
422
423Added new function (ext2fs_allocate_tables) which allocates the
424meta-data blocks as part of initializing a filesystem. (moved from
425mke2fs code).
426
427Added a new I/O manager for testing purposes. It will either allow a
428program to intercept I/O requests, or print debugging messages to
429trace the activity of a program using the I/O manager.
430
431The badblocks_list functions now store the bad blocks in a sorted
432order, and use a binary search to speed up badblocks_list_test.
433
434The inode scan function ext2fs_get_next_inode() may now return a soft
435error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
436those cases where part of an inode table is missing or there is a bad
437block in the inode table.
438
439Added a new function (ext2fs_block_iterate2) which adds new arguments to
440the callback function to return a pointer (block and offset) to the
441reference of the block.
442
443Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
444application to jump to a particular block group while doing an inode
445scan.
446
447The badblocks list functions were renamed from badblocks_* to
448ext2fs_badblocks_*. Backwards compatibility functions are available
449for now, but programs should be modified to use the new interface.
450
451Some of the library functions were reorganized into separate files to
452reduce the size of some programs which statically link against the
453ext2 library.
454
455Put in some miscellaneous fixes for the Alpha platform.
456
Theodore Ts'o5c576471997-04-29 15:29:49 +0000457
458E2fsprogs 1.06 (October 7, 1996)
459================================
460
461Fixed serious bug in e2fsck: if the block descriptors are bad, don't
462smash the backup copies in ext2fs_close(). (The problem was that when
463e2fsck -p discovered the problem, while it was closing the filesystem
464and exiting, it was also blowing away the backup superblocks on the
465disk, which was less than friendly.) We now make it the case that we
466only write out the backup superblock and the back block descriptors if
467the filesystem is completely free from problems.
468
469Fixed a bug in block_interate in the lib/ext2fs library which caused
470e2fsck to fail on GNU Hurd-created filesystems.
471
472Add support for Linux/FT's bootloader, which actually uses
473EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
474to clear the inode.
475
476Add support for the "A" (no atime update) attribute. (Note: this
477attribute is not yet in production kernels.)
478
479The test suite is not automatically run when doing a "make all" from
480the top level directory. Users should manually run "make check" if
481they wish to run the test suite.
482
483Upon a preenhalt(), make the printed message more explicit that
484running e2fsck "MANAULLY" means without the -p or -a options.
485
486In e2fsck, if a disconnected inode is zero-length, offer to clear it
487instead of offering to connect it to lost+found.
488
489In e2fsck, if a filesystem was just unmounted uncleanly, and needs
490e2fsck to be run over it, change e2fsck to explicitly display this
491fact.
492
493For dumpe2fs and e2fsck, cause the -V option to print out which
494version of the ext2fs library is actually getting used. (This will
495help detect mismatches of using a 1.06 utility with a 1.05 library,
496etc.)

501EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
502the naming convention.
503
504In ext2fs_initialize(), make sure the description for the inode bitmap
505is correctly initialize.
506
507Fixed minor type typo in ext2fs_allocate_generic_bitmap();

Theodore Ts'ofc6d9d51997-04-29 14:51:31 +0000509E2fsprogs 1.05 (September 7, 1996)
510==================================
511
512Add support for new fields in the ext2 superblock --- volume name,
513volume UUID, and last mounted field. Dumpe2fs displays these fields,
514tune2fs and mke2fs allows you to set them. E2fsck will automatically
515generate a UUID for those volumes that don't have them.
516
517Put in support for e2fsck to recognize HURD specific ext2 features ---
518most notably, the translator block. The e2fsprogs tools will now use
519the creator_os field in the superblock to correctly handle different
520OS-specific variants of the ext2 filesystem.
521
522E2fsck now fixes inodes which have a the deletion time set, but which
523have a non-zero i_link_count field by offering to clear the deletion
524time. Previously e2fsck assumed that the inode was deleted (per 0.3c
525ext2 kernel behavior) and offered to unlink the file.
526
527If e2fsck sets the clean bit, but nothing else, set the exit code
528FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
529set the filesystem valid bit when it was previously cleared. :-) This
530was needed to make the HURD fsck driver happy.
531
532If the user refuses to attach an unattached inode, e2fsck will no
533longer set the inode's link count. Otherwise, the inode would end up
534getting marked as unused, which might cause loss of data later.
535
536Make the message issued by e2fsck when the superblock is corrupt less
537confusing for users. It now mentions that another reason for the
538"corrupt superblock" message might be that the partition might not be
539an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
540
541Make the libext2 library more robuest so that e2fsck won't coredump on
542an illegal superblock where the blocksize is zero. (f_crashdisk is
543the test case).
544
545By default, create filesystems where the default checkinterval is 6
546months (180 days). Linux servers can be robust enough that 20 reboots
547can be a long, long time.
548
549Added configure flag --enable-old-bitops, which forces the bitops to
550use the old (native) bitmask operations. By default on the sparc
551platform, the standard ext2 bit ordering is now used.
552
553Added a new feature to e2fsck to byte-swap filesystems; this can be
554used to convert old m68k filesystems to use the standard byte-order
555storage for the superblock, inodes, and directory blocks. This
556function is invoked by using the '-s' option to e2fsck.
557
558Debugfs's "dump" command has been enhanced so that it writes out the
559exact size of the file so that the nulls at the end of the file are
560eliminated. The command also accept a new "-p" option which will
561attempt preserve to preserve the ownernship, permissions, and
562file modification/access times.
563
564Debugfs has two new options, -f and -R. The -R option allows the user
565to execute a single debugfs command from the command line. The -f
566option allows the user to specify a "command file" containing debugfs
567commands which will get executed.
568
569Dumpe2fs now pretty prints the check interval, instead of just
570printing the check interval as a number of seconds.
571
572Fix bugs in debugfs: the params command when no filesystem is opened
573no longer causes a core dump. It is now possible to unlink a file
574when a pathame containing a '/' is specified.
575
576Tune2fs has a new -C option which sets the number of times the
577filesystem has been mounted.
578
579Fix the chattr '-v' option so that it actually works. Chattr was
580being buggy about the -v option parsing.
581
582Programmers' notes:
583-------------------
584
585The directory lib/uuid contains a set of library routines to generate
586DCE compatible UUIDs.
587
588Extended ext2fs_namei() to handle symbolic links. Added new function
589ext2fs_nami_follow() which will follow last symbolic link in the case
590where the pathname points to a sym link.
591
592The ext2fs_block_iterate function will now return the HURD translator
593block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
594iterator to return data blocks only. The ext2fs.h file now defines
595constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
596BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
597count field of the iterator callback function.
598
599The test script driver now takes an optional second argument, which is
600the test case to be run. This allows you to run a test case without
601needing to run the entire test suite.
602
603On Linux ELF systems, install the .so files in the correct places
604(/usr/lib). The .so files must be stored in the same directory as the
605.a files.
606
607Fixed miscellaneous HURD compilation issues with header file being
608included in the right order.
609
610Fixed debugfs so that it resets optind to zero, not one, since setting
611optind to zero is more correct.

Theodore Ts'oa4d09611997-04-29 14:28:00 +0000614E2fsprogs 1.04 (May 16, 1996)
615=============================
616
617First "official" (1.03 was a limited release only) to support building
618e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
619kernels).
620
621This package includes a RPM specs file, that it can be built using the
622RedHat Package Manager.
623
624E2fsck now prints a hint that if there are lots of incorrectly located
625inode bitmaps, block bitmaps, and inode table blocks, the user might
626want to try using e2fsck -b 8193 first, to see if that fares any
627better.
628
629For ext2 filesystem written with the hurd, debugfs will now print out
630the translator field when printing an inode structure.
631
632Lots of miscellaneous linking/installation cleanups:
633
634 Libraries are now linked using a relative pathname, instead of
635 relying on -L working correct. It doesn't, in many cases, including
636 current versions of GNU ld. This guarantees that the build tree is
637 linking with the right libraries, instead of the ones installed in
638 /usr/lib.
639
640 Header files, man pages, and the et/ss shell scripts are now
641 generated using a custom substitution script, instead of relying on
642 the configure script. This prevents needless recompilation of
643 files; in addition, the custom substitution script is much faster.
644
645 e2fsck may now be linked dynamically, by using the
646 --enable-dynamic-e2fsck flag to configure. This is not recommended,
647 since it increases e2fsck's dependence on other files, but some
648 people need to save disk space, and other critical programs on their
649 systems were being linked dynamically anyway.
650
651 Programs such as fsck which didn't need to be linked against
652 libext2fs (or mke2fs which didn't need to be linked against libe2p)
653 only link against libraries they actually need. Otherwise, those
654 programs would require the presense of libraries that otherwise
655 could be removed from a rescuse diskette.
656
657 The ss include files are now installed correctly so they can
658 actually be used by another package.
659
660 If the profiling libraries are built, they are now installed on a
661 "make install-libs".

Theodore Ts'o7f88b041997-04-26 14:48:50 +0000664E2fsprogs 1.03 (March 27, 1996)
665===============================
666
667Change the m68k bit numbering for bitmasks to match the bit numbering
668used by all other ext2 implementations. (This change was requested by
669the m68k kernel development team.)
670
671Support (in-development) filesystem format revision which supports
672(among other things) dynamically sized inodes.
673
674Fixed a bug in the ext2 library so that an intelligent error is
675returned if mke2fs is run with a ridiculously small number of blocks
676for a partition.
677
678Fixed a bug in the ext2 library which required that the device be
679openable in read/write mode in order to determine its size. This
680caused e2fsck -n to require read/write access when it was not
681previously necessary.
682
683Fixed a bug in e2fsck which casued it to occasionally fail the test
684suite depending on which version of the floating point library it was
685using.
686
687Fixed a bug in e2fsck so that it now halts with a fatal error when
688certain superblock consistency checks fail. Previously it continued
689running e2fsck, with some potential confusing/damaging consequences.
690
691Added new flag to fsck which allows the root to be checked in parallel
692with other filesytems. This is not the safest thing in the world to
693do, but some system administrators really wanted it.
694
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +0000695Fixed -Wall flames in lib/ss.
696
Theodore Ts'o74becf31997-04-26 14:37:06 +0000697
698E2fsprogs 1.02 (January 16, 1996)
699=================================
700
701Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
702
703Change e2fsck to print statistics of how many non-contiguous files are
704on the system. Note that a file which is larger than 8k blocks, it is
705guaranteed to be non-contiguous.
706
707In mke2fs, print a warning message if a user tries to format a whole
708disk (/dev/hda versus /dev/hda1). If a user really wants to format a
709whole disk, the -F (force) option forces mke2fs to format a whole disk
710as a filesytem.
711
712Fix a bug in fsck where in some cases it might start checking
713partitions in the next pass before it finishes checking partitions in
714the current pass. This still won't cause two partitions on the same
715disk will be checked, so it's rarely a problem in real life.
716
717Patch lsattr so that it won't hang when checking a named pipe.
718
719Minor compilation fixes:
720 * Fix the order of libraries that were linked in debugfs.
721 * Allow the sources to be compiled with -ansi turned on.
