1 2002-11-07 <tytso@snap.thunk.org>
3 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
4 support when the MASTER_SB_ONLY flag is set. Some of
5 the descriptor blocks that should have been written out
8 2002-10-31 Theodore Ts'o <tytso@mit.edu>
10 * Release of E2fsprogs 1.30
12 2002-10-31 Theodore Ts'o <tytso@mit.edu>
14 * ext2_fs.h: Add support for a new inode flag, which is to be used
15 for indicating the top of directory hierarchies for the
16 Orlov block allocator.
18 * ismounted.c (check_mntent, check_mntent_file): Add better
19 support for loopback-mounted filesystems. Check /etc/mtab
20 if /proc/mounts doesn't turn up any mount flags, since
21 /etc/mtab has the loopback image filename, instead of
22 /dev/loop0. Also, check based on st_dev and st_ino, so
23 that if a relative pathname or a pathnames using symbolic
24 links are used, we can detect the the filesystem correctly
25 in those cases. (Addresses Sourceforge bug #619119)
27 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
28 don't try the FDFLUSH ioctl that was required for floppies
29 with older kernels. This avoids needless whining from the
30 MD device driver. (Addresses Sourceforge bug #545832).
32 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
33 wrong group_block to ext2fs_descriptor_block_loc if we're
34 using the backup superblock/block group descriptors.
35 (ext2fs_descriptor_block_loc): If we're using the backup
36 superblock descriptors, use the backup descriptor block in
39 2002-10-30 Theodore Ts'o <tytso@mit.edu>
41 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
42 table so that it buts up against the bitmap blocks, to
43 avoid block fragmentation.
45 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
46 bug; only allocate group descriptor blocks up to
49 2002-10-25 Theodore Ts'o <tytso@mit.edu>
51 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
52 know when a filesystem was created. (Sometimes this can
55 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
57 2002-10-20 Theodore Ts'o <tytso@valinux.com>
59 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
60 the journal data mode.
62 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
63 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
64 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
65 the meta_blockgroup filesystem format.
67 2002-10-15 <tytso@snap.thunk.org>
69 * ext2_fs.h: Add new field in superblock for default mount options.
71 2002-10-13 Theodore Ts'o <tytso@mit.edu>
73 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
76 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
78 * rw_bitmaps.c (ext2fs_write_block_bitmap,
79 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
80 because the bitmap is getting written to disk. Make
81 ext2fs_swap_bitmap be a static function, since it's not
82 intended to be exported.
84 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
86 2001-09-24 Theodore Tso <tytso@mit.edu>
88 * Release of E2fsprogs 1.29
90 2001-08-31 Theodore Tso <tytso@thunk.org>
92 * Release of E2fsprogs 1.28
94 2002-08-31 Theodore Ts'o <tytso@valinux.com>
96 * dblist.c (ext2fs_dblist_sort): New function which allows the
97 caller to pass in a special sort comparison function.
99 2002-08-20 Theodore Ts'o <tytso@mit.edu>
101 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
102 failed to accurately characterize non-standard slow
103 symlinks. (Which don't appear in practice on real-life
104 systems, fortunately.)
106 2002-08-17 Theodore Ts'o <tytso@mit.edu>
108 * Makefile.in: Remove inode_io.o from the standard object files,
109 and only build it if debugfs is enabled (it requires
110 fileio.o, which is only built if --disable-debugfs isn't
111 specified to configure).
113 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
114 incompatible way so that it is no longer
115 endian-dependent. Add the TEA hash. Allow the seed
116 parameter to be optional.
118 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
119 These features are all now in the HALF_MD4 hash. Add
120 definition for EXT2_HASH_TEA.
122 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
123 a pointer instead of an array.
125 2002-08-16 Theodore Ts'o <tytso@mit.edu>
127 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
129 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
130 the number of data blocks used by an inode exclusive of
133 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
134 adjusts the reference count in an extended attribute block.
136 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
137 correctly deal with extended attribute blocks in symbolic
140 2002-08-13 <tytso@snap.thunk.org>
142 * Makefile.in: Move dupfs.o and test_io.o from the
143 needed-by-debugfs object list to the needed-by-resizer
144 object list. Fixes compile problem if the system is built
145 with only --disable-debugfs.
147 2002-07-29 Theodore Ts'o <tytso@mit.edu>
149 * link.c (ext2fs_link): When adding a new link to a directory,
152 2002-07-23 Theodore Ts'o <tytso@mit.edu>
154 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
155 calculations for names > 32 characters to be completely
156 bogus. Changed MD4 calculation to match what is currently
157 being used in the CVS gkernel tree.
159 2002-07-19 Theodore Ts'o <tytso@mit.edu>
161 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
162 superblock definition.
164 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
165 create a set of u32_list functions.
167 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
168 since that's required by the directory indexing code.
170 2002-07-14 Theodore Ts'o <tytso@mit.edu>
172 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
173 using a C++ reserved word.
175 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
176 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
177 old version of glibc (built against 2.2 headers) will
178 interact badly with the workaround to actually cause more
179 problems. I hate it when the glibc folks think they're
180 being smarter than the kernel....
182 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
184 * ext2_fs.h: Add superblock field for reserved group descriptors.
186 2002-06-28 Theodore Ts'o <tytso@mit.edu>
188 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
189 ext2fs_cpu_to_{l,b}e{32,16}
191 2002-06-27 Theodore Ts'o <tytso@mit.edu>
193 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
194 Add appropriate fallbacks in this case.
196 2002-06-26 Theodore Ts'o <tytso@mit.edu>
198 * dirhash.c (ext2fs_dirhash): Change function signature to support
199 a hash seed, and to return the minor hash (for 64-bit hash
200 support). Add support for the half MD4, half MD4 with
201 seed, and half MD4 with seed and 64 bits.
203 2002-06-15 Theodore Ts'o <tytso@mit.edu>
205 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
207 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
209 * ext2_fs.h: Add macros for maximum block/inode counts:
210 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
211 and EXT2_MAX_INODES_PER_GROUP.
213 * openfs.c (ext2fs_open): Check that the number of blocks in a group
214 is less than 2^16, otherwise we need an INCOMPAT flag (not
215 in existence yet, if ever) to open such a filesystem.
217 * initialize.c (ext2fs_initialize): Limit the number of blocks and
218 inodes in a group to less than 2^16.
220 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
222 * ext2_fs.h: Further minor cleanups of the header. Consolidate
223 some checks for __KERNEL__ into one place.
225 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
227 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
228 the EXT2_SB() macro instead. Remove kernel function
229 prototypes also. This matches the 2.5 kernel, and
230 is also cleaner for other reasons. Whitespace cleanup.
232 2002-05-21 Theodore Ts'o <tytso@mit.edu>
234 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
236 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
238 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
240 * initialize.c (ext2fs_initialize): Remove assumption that
241 blocksizes are always <= 4k.
243 2002-05-11 Theodore Ts'o <tytso@mit.edu>
245 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
246 silently if inode pointer is NULL (and ext2fs_bmap is
247 expected to read the inode itself).
249 2002-04-27 Theodore Ts'o <tytso@mit.edu>
251 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
252 file we are checking is a block device file before looking
253 at st_rdev, since it's not valid for normal files.
254 (is_swap_device): Move so that it is outside the
255 HAVE_MNTENT_H, so that it is always built.
257 2002-03-11 Theodore Tso <tytso@mit.edu>
259 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
260 functions which take an extra flags argument. The flag
261 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
262 field is byte swampped on big-endian machines, since in
263 the V2 structure, name_len is a char field which is
264 doesn't need to be byte swapped --- except if an
265 old-style kernel had byte-swapped the name_len field
266 as part of the V1 structure.
268 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
270 * dirhash.c (ext2fs_dirhash): New function which calculates the
271 hash for a filename in an indexed directory.
273 2002-03-08 Theodore Tso <tytso@mit.edu>
275 * Release of E2fsprogs 1.27
277 2002-03-07 Theodore Tso <tytso@mit.edu>
279 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
281 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
282 tst_byteswap.c: Fix gcc -Wall complaints
284 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
285 (From Philipp Thomas <pthomas@suse.de>)
287 2002-02-25 Theodore Tso <tytso@mit.edu>
289 * ext2_fs.h: Add structure definitions for the directory indexing
292 2002-02-23 Theodore Tso <tytso@mit.edu>
294 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
295 it doesn't break things on mis32, sparc32, and alpha
298 2002-02-21 Theodore Tso <tytso@mit.edu>
300 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
301 we were missing an fclose().
303 2002-02-20 Theodore Tso <tytso@mit.edu>
305 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
306 abstraction interface which exports an ext2 inode.
308 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
309 as a public interface. Change void * to const void * in
310 ext2fs_file_write's interface.
312 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
313 conditional; save a few bytes.
315 2002-02-12 Theodore Tso <tytso@mit.edu>
317 * Makefile.in (tst_badblocks): Add some extra .o files when
318 linking the debugging program tst_badblocks which are
319 needed if we aren't compiling with inline functions enable.
321 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
322 define away __inline__ since it may not be supported.
324 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
325 stripped down jbd_debug that doesn't use variadic
326 arguments. This will cause warnings under AIX, but things
329 2002-02-03 Theodore Tso <tytso@thunk.org>
331 * Release of E2fsprogs 1.26
333 2002-02-03 Theodore Tso <tytso@mit.edu>
335 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
336 so that the number of directories in use is adjusted
339 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
340 which optionally will modify the number of directories
343 2002-01-03 Theodore Tso <tytso@mit.edu>
345 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
346 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
347 which will return deleted directory entries.
348 ext2fs_dir_iterate2 takes a new callback function which
349 is identical with the one used by
350 ext2fs_dblist_dir_iterate(). If the directory entry is
351 deleted, the callback function will be called with the
352 entry paraemter set to DIRENT_DELETED_FILE.
354 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
355 ext2fs_block_alloc_stats): New functions which update
356 block/inode allocation statistics in the bitmaps, block
357 group descriptors, and superblock.
359 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
360 expanddir.c (expand_dir_proc), bb_inode.c
361 (clear_bad_block_proc, set_bad_block_proc,
362 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
363 Update to use new block/inode allocation statistics.
365 2001-12-24 Theodore Tso <tytso@mit.edu>
367 * ismounted.c (is_swap_device): New function used by
368 ext2fs_check_if_mounted and ext2fs_check_mount_point which
369 determines whether or not the specified device is a swap
370 device by using /proc/swaps. More bulletproofing for
371 idiotic/careless system administrators!
373 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
374 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
375 field to struct_ext2_filsys, umask. This field is
376 initialize to 022, and affects ext2fs_mkdir in the obvious
377 way. (In the future umask should also affect new file
378 creation routines, but the fileio functions don't
379 currently support this yes.)
381 * ismounted.c (check_mntent_file): Stat all of the entries in
382 /etc/mtab and/or /proc/mounts in order to catch dim-witted
383 system administrators who might have created alias
386 2001-12-23 Theodore Tso <tytso@mit.edu>
388 * Makefile.in, jfs_user.h: Move linux/jbd.h to
389 ext2fs/kernel-jbd.h, to avoid using the system header
390 file version of hbd.h when using diet glibc (since it
391 forcibly adds /usr/include to the beginning of the
392 include search path.)
394 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
395 include/linux directory.
397 2001-12-16 Theodore Tso <tytso@mit.edu>
399 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
400 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
401 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
403 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
406 2001-12-03 Theodore Tso <tytso@mit.edu>
408 * unix_io.c (unix_open): Make sure the ulimit workaround works
409 regardless of the version of glibc which is used to
412 2001-11-26 Theodore Tso <tytso@mit.edu>
414 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
415 trying to unset the filesize limit if at all possible,
416 if a block device is getting opened. (The filesize limit
417 shouldn't be applied against writes to a block device, but
418 starting in 2.4.10, the kernel is doing this.)
420 2001-11-05 Theodore Tso <tytso@mit.edu>
422 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
423 file on adding a journal to an already-mounted filesystem,
424 try to clear the ext2 file attributes on an already
425 existing .journal file so that we don't fail if on a
426 partially added journal to the filesystem.
428 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
429 which signals that a particular inode should not have the
430 last bits of data (the "tail") be merged with another
431 file. This is necessary to keep LILO happy.
433 2001-09-20 Theodore Tso <tytso@thunk.org>
435 * Release of E2fsprogs 1.25
437 2001-09-16 Theodore Tso <tytso@mit.edu>
439 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
440 which was breaking the build on the Hurd. (Addresses
443 2001-09-13 Theodore Ts'o <tytso@mit.edu>
445 * ismounted.c (check_mntent_file): We now validate the entry in
446 /etc/mtab to make sure the filesystem is really mounted,
447 since some broken distributions (read: Slackware) have
448 buggy boot scripts that don't initialize /etc/mtab before
449 checking non-root filesystems. (Slackware also doesn't
450 check the root filesystem separately, and reboot if the
451 root filesystem had changes applied to it, which is
452 dangerous and broken.)
454 2001-09-02 Theodore Tso <tytso@thunk.org>
456 * Release of E2fsprogs 1.24a
458 2001-08-30 Theodore Tso <tytso@thunk.org>
460 * Release of E2fsprogs 1.24
462 2001-08-30 Theodore Tso <tytso@valinux.com>
464 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
465 changes, since the ioctl number has been reused by another
468 2001-08-15 Theodore Tso <tytso@valinux.com>
470 * Release of E2fsprogs 1.23
472 2001-08-05 Theodore Tso <tytso@valinux.com>
474 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
475 version of the bitmap test routines to speed up these
476 routines. (At some point I may want to make these
477 routines use the find_first_bit functions, but that will
478 add a lot of complexity since it means that these
479 functions will have to break the bitmap abstraction
480 boundary. It's not clear it's worth it.)
482 * mkjournal.c (mkjournal_proc): Remember the last block allocated
483 to speed up ext2fs_new_block().
485 2001-07-29 Theodore Tso <tytso@valinux.com>
487 * finddev.c (scan_dir): Fix memory leak; we weren't calling
488 closedir() when exiting the function in all cases.
490 2001-07-27 Theodore Tso <tytso@valinux.com>
492 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
493 block usable in the journal for external journals to be 2
494 or 3, depending on the blocksize, so that the existing
495 kernel code does the right thing.
497 * getsize.c (ext2fs_get_device_size): Add support for the
498 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
499 from Ben LaHaise, but it's likely this interface won't
502 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
503 when writing the journal superblock, too. (Oops! Needed
504 to make 1k filesystems with external journal to work.)
506 2001-07-26 Theodore Tso <tytso@valinux.com>
508 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
509 to find the journal superblock if the blocksize is 1024.
511 2001-07-21 Theodore Tso <tytso@valinux.com>
513 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
515 2001-07-20 Theodore Tso <tytso@valinux.com>
517 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
518 attribute block, set the filesystem changed bit.
520 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
521 Comment out these functions since we're not using them.
523 2001-07-10 Theodore Tso <tytso@valinux.com>
525 * closefs.c (write_primary_superblock): After writing changes to
526 the primary superblock, update the original superblock
527 copy so we don't have to re-write those changes in the
529 (ext2fs_flush): Clear the superblock dirty flag after
530 we've flushed out changes to disk.
532 2001-07-07 Theodore Tso <tytso@valinux.com>
534 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
535 to avoid register conflicts when compiling in PIC mode.
537 2001-07-04 Theodore Tso <tytso@valinux.com>
539 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
540 Add new functions (C and in i386 assembler) which quickly
541 find bits set in a bitmask.
543 2001-06-23 Theodore Tso <tytso@valinux.com>
545 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
546 ext2_ext_attr.h and ext_attr.c for extended attributes
549 * Release of E2fsprogs 1.22
551 2001-06-22 Theodore Tso <tytso@valinux.com>
553 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
554 descriptor so that adding a journal to a mounted
555 filesystem doesn't die. (Fixes a bug accidentally
556 introduced in e2fsprogs 1.21.)
558 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
559 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
560 fchflags without defining UF_NODUMP. (Addresses Debian
563 * flushb.c: Use platform independent method of defining the
564 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
565 since on newer glibc's BLKFLSBUF is defined there.
567 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
568 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
569 to support byte swapping even if we don't support the
570 conversion functions. (Fixes Debian bug #101686).
572 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
573 since the byte-swapping code all assumes the
574 ext2_dir_entry structure. (It's a question of whether or
575 not name_len should be byte-swapped or not, and whether
576 it's a 16 bit or 8 bit field.)
578 2001-06-15 Theodore Tso <tytso@valinux.com>
580 * Release of E2fsprogs 1.21
582 2001-06-15 Theodore Tso <tytso@valinux.com>
584 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
585 file which is generated and is therefore found in the
586 build directory, not source directory.
588 * ismounted.c (check_mntent_file): Use a test file in / to check
589 to see if the root filesystem is mounted read-only. This
590 protects against the case where /etc might not be on /, as
591 well as the case where /etc/mtab doesn't exist. (Both are
592 should-never happen scenarios, but you never know...)
594 2001-06-14 Theodore Tso <tytso@valinux.com>
596 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
597 Remove unneeded #pragma argsused, since the arguments are
600 2001-06-13 Theodore Tso <tytso@valinux.com>
602 * ext2_types.h.in: If linux/types.h has been defined, then don't
603 try to redefine the typedefs.
605 * Makefile.in (HFILES): Add ext2_types.h to the list of files
606 which should be installed.
608 * ismounted.c (check_mntent_file): Work around GNU hurd brain
609 damage. Addresses Debian bug #100304.
611 * Makefile.in: Limit some .o files from being included into the
612 library if --disable-debugfs, --disable-swapfs,
613 --disable-imager, or --disable-resizer are used.
615 2001-06-12 Theodore Tso <tytso@valinux.com>
617 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
618 function, and use the ext2fs_badblocks_* functions
621 2001-06-11 Theodore Tso <tytso@valinux.com>
623 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
624 ext2fs_mark_generic_bitmap and
625 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
626 functions. (This saves space and doesn't significantly
627 change the speed of e2fsck on a P-III.)
629 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
630 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
631 include the byte-swapping logic if ENABLE_SWAPFS is turned
632 on or if we're on a big-endian machine.
634 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
635 set EXT2_FLAG_SWAP_BYTES, instead of using
638 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
639 autoconf to determine whether or not return
640 EXT2_FLAG_SWAP_BYTES.
642 2001-06-10 Theodore Tso <tytso@valinux.com>
644 * Makefile.in: Remove the dependence on the libe2p library.
646 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
647 with direct usage of the ioctl/fchflags so that we don't
648 have to depend on the libe2p library.
650 2001-06-08 Theodore Tso <tytso@valinux.com>
652 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
653 when trying to find a 32-bit wide type.
655 * icount.c (insert_icount_el): Fix the code used to estimate the
656 size of the new icount array to be more intelligent, to
657 avoid reallocating the array too many times. Thanks to
658 Enrique Perez-Terron for pointing this out.
660 2001-06-02 Theodore Tso <tytso@valinux.com>
662 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
663 for a symlink to determine whether it is a fast symlink.
665 2001-06-01 Theodore Tso <tytso@valinux.com>
667 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
668 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
670 2001-05-25 Theodore Tso <tytso@valinux.com>
672 * Release of E2fsprogs 1.20
674 2001-05-25 Theodore Tso <tytso@valinux.com>
676 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
677 some to clean up Andreas's patches. Use strncpy instead
678 of strcpy to save the root's mountpoint. Clean up #ifdef
679 structure. Remove uneeded variable in testing/debug driver.
681 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
683 * ismounted.c: Add check for root device which doesn't depend on
684 /etc/fstab or /proc/mounts to be correct. Don't call
685 endmntent() before we are done with mnt struct.
687 2001-05-23 Theodore Tso <tytso@valinux.com>
689 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
692 2001-05-21 Theodore Tso <tytso@valinux.com>
694 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
695 make room for pre-existing usage of
696 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
697 the same codepoint as EXT2_BTREE_FL.
699 2001-05-20 Theodore Tso <tytso@valinux.com>
701 * ext2fs.h: #include <> instead of "" for ext2fs and et header
702 files, since they will be installed in /usr/include
704 2001-05-14 Theodore Tso <tytso@valinux.com>
706 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
707 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
708 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
709 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,

717 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
718 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
719 Adjust all files in this directroy to include this file.
721 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
724 2001-05-05 Theodore Tso <tytso@valinux.com>
726 * fileio.c (ext2fs_file_read): Factored out common code and
727 cleaned up function. Fixed a bug where if there was an
728 error reading from the disk, the number of bytes read
729 wasn't reliably set. (Fixes Debian bug #79163)
730 (ext2fs_file_write): Factored out common code and made
731 function more efficient; if writing a full block, don't
732 bother to do a read-modify-write cycle.
734 2001-05-04 Theodore Tso <tytso@valinux.com>
736 * dirblock.c (ext2fs_read_dir_block): Check for an directory
737 record length which isn't a multiple four, and treat that
738 as an invalid. Scan the directory and return an error
739 (EXT2_ET_DIR_CORRUPTED) if the directory records are
741 (ext2fs_write_dir_block): If while byte-swapping the
742 directory block, if there's an error, abort and return
743 EXT2_ET_DIR_CORRUPTED.
745 2001-05-02 Theodore Tso <tytso@valinux.com>
747 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
748 image_header field in the ext2_filsys structure
750 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
751 * inode.c (ext2fs_read_inode):
752 * rw_bitmaps.c (read_bitmaps):
753 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
755 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
756 sure the full bitmap is saved.
758 2001-05-01 Theodore Tso <tytso@valinux.com>
760 * e2image.h (struct ext2_image_hdr): Add space for the device name
763 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
764 make sure the rec_len is a multiple of 4, to prevent
765 bus-errors on architectures which care about mis-aligned
768 2001-04-25 Theodore Tso <tytso@valinux.com>
770 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
771 query the device sizes using the BLKGETSIZE ioctl.
773 2001-04-16 Theodore Tso <tytso@valinux.com>
775 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
776 before checking /etc/mtab. The EXT2_MF_READONLY flag is
777 now set from the /etc/mtab options field for all
778 filesystems, not just the root filesystem. Add debugging
779 code to make it easier to test ext2fs_check_if_mounted().
781 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
782 check; return an error if there's an attempt to create a
783 journal less than 1024 filesystem blocks.
785 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
786 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
788 2001-02-20 Theodore Tso <tytso@valinux.com>
790 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
793 * tst_byteswap.c: New function to test the byteswap functions.
794 Add to regression test suite.
796 2001-02-08 Theodore Tso <tytso@valinux.com>
798 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
800 2001-02-07 Theodore Tso <tytso@valinux.com>
802 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
803 of s_first for external devices to always be 1, since
804 jsb->s_first is always relative to the start of the
805 journal superblock. Use htonl(1) when setting s_nr_users.
807 2001-01-17 Theodore Ts'o <tytso@valinux.com>
809 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
810 device number of the filesystem (instead of the journal)
811 was being dropped into s_journal_dev.
813 2001-01-15 Theodore Ts'o <tytso@valinux.com>
815 * initialize.c (ext2fs_initialize): Add support for initializing
816 the ext2 superblock for external journal devices. This
817 basically means we don't bother to allocate any block
820 * openfs.c (ext2fs_open): Only open external journal devices if
821 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
822 ext2fs_open. When opening such devices, don't try to read
823 the block group descriptors, since they're not there.
825 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
827 * mkjournal.c: Export a new function,
828 ext2fs_create_journal_superblock(), which allocates and
829 returns a buffer containing a journal superblock. This is
830 needed by mke2fs to create an external journal. Rewrote
831 ext2fs_add_journal_device() so that it no longer creates
832 the external journal, but rather adds a filesystem to an
833 existing external journal. It handles all of the UUID
836 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
837 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
838 Changed function prototype for ext2fs_add_journal_device().
840 2001-01-14 Theodore Ts'o <tytso@valinux.com>
842 * closefs.c (ext2fs_flush): Don't write out anything beyond the
843 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
846 2001-01-12 Theodore Ts'o <tytso@valinux.com>
848 * imager.c: Fix gcc -Wall complaints and a series of bugs where
849 retval wasn't set correctly. (Thanks to Andreas Dilger
850 for pointing this out.)
852 2001-01-11 <tytso@snap.thunk.org>
854 * flushb.c (ext2fs_sync_device): New function which centralizes
855 all of the places which might try to use the BLKFLSBUF
856 or FDFLUSH ioctls (and usually failing to define them
857 since the system header files don't usually do this for
858 us, and we're trying to avoid usage of kernel include
861 2001-01-10 <tytso@snap.thunk.org>
863 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
864 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
865 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
866 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
867 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
868 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
869 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
870 ext2_ino_t, to protect applications that attempt to
871 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
872 changes ino_t(!?). So we use ext2_ino_t to avoid an
873 unexpected ABI change.
875 2001-01-05 <tytso@snap.thunk.org>
877 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
878 we may overrun allocated memory in case of a corrupted
879 filesystem (or an e2fsck test case :-) when byte-swapping
882 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
884 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
885 complaints including a missing return 0 at the end of
886 ext2fs_add_journal_device.
888 2001-01-03 <tytso@snap.thunk.org>
890 * Makefile.in: Link in libe2p when creating libext2fs as a shared
891 library, since mkjournal.c now references fsetflags().
893 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
894 Dilger's changes (with fixups) to allow on-line creation
897 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
898 EXT2_FLAG_SUPER_ONLY, which the close routines to only
899 update the superblock, and not the group descriptors.
901 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
903 * ismounted.c: add ext2fs_check_mount_point() function, which will
904 optionally return the mount point of a device if mounted
906 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
908 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
909 ext2fs_add_journal_inode()
911 2001-01-01 <tytso@snap.thunk.org>
913 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
914 source (but not binary) compatibility of some users of the
915 ext2 library. They should just simply do a global search
916 and replace of struct ext2fs_sb with struct
917 ext2_super_block, and use their own private copy of
918 ext2_fs.h if they aren't already.
920 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
921 Replace use of ext2fs_sb with ext2_super_block.
923 2000-12-31 <tytso@snap.thunk.org>
925 * ext2fs.h: Cleaned up header file by removing definitions of
926 feature flags that might not have been defined in older
927 ext2 header files. Now that we're using our own
928 include/linux/ext2fs.h header file, this can never happen.
930 * jfs_dat.h: Removed old header file which is no longer needed.
932 2000-12-13 Theodore Ts'o <tytso@valinux.com>
934 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
935 by Andreas Dilger to update the filesystem revision to
938 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
941 2000-12-09 <tytso@snap.thunk.org>
943 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
944 ext2fs_add_journal_device): Add a new argument to the APIs
945 of these function, which is a flags word. This is used to
946 allow the creation of a V1 superblock for those folks who
947 are using ext3 0.3b in production. Note, the user-land
948 interface for getting at this flag won't be documented, as
949 the V1 superblock is deprecated.
951 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
952 which creates a V2 superblock instead of a V1 superblock.
954 2000-11-21 <tytso@snap.thunk.org>
956 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
957 out by Andreas Dilger.
959 2000-11-05 <tytso@snap.thunk.org>
961 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
962 ext2_fs.h, Makefile.in: New file that has routines that
963 save ext2fs metadata to a file.
965 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
967 * e2image.h: New file which defines the file format for the ext2
968 image file. (Saved copy of ext2 metadata to a file as a
969 saving throw against worst-case damage.)
971 2000-11-01 <tytso@snap.thunk.org>
973 * inode.c (ext2fs_flush_icache): Add new function
974 ext2fs_flush_icache() which flushes the internal inode
975 cache. Applications which modify the inode table blocks
976 directly must call this function.
978 2000-10-26 <tytso@snap.thunk.org>
980 * mkjournal.c: Add #include of netinet/in.h, since Solaris
981 requires it for ntohl().
983 * ext2_io.h (io_channel_write_byte): Add new interface to allow
984 callers to write specific byte ranges. This is an
985 optional interface, which not all IO channels may
988 * unix_io.c (unix_write_byte):
989 * test_io.c (test_write_byte): Add implementation of the
992 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
993 function which writes the primary superblock. If the IO
994 channel supports writing raw bytes directly, only fields
995 which were modified are written to the disk. This makes
996 it safe(r) to use utilities like tune2fs on a mounted
999 * freefs.c (ext2fs_free): Free the original superblock if it is
1002 * openfs.c (ext2fs_open): Store a copy of the original superblock
1005 * ext2fs.h: Add a field to store the original superblock in the
1006 ext2 context structure.
1008 2000-10-24 <tytso@snap.thunk.org>
1010 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
1011 don't need to use llseek).
1013 2000-10-24 <tytso@valinux.com>
1015 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
1016 creating an ext3 journal on a filesystem.
1018 2000-08-21 <tytso@valinux.com>
1020 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
1022 2000-08-22 <tytso@valinux.com>
1024 * unix_io.c: Make massive changes to support a multiple block
1025 writethrough cacheing.
1027 * ext2_io.h: Added flags field to the io_channel structure.
1029 2000-08-19 <tytso@valinux.com>
1031 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
1032 provides the function ext2fs_find_block_device(). This
1033 function returns the pathname to a block device, given its
1036 2000-07-13 <tytso@valinux.com>
1038 * Release of E2fsprogs 1.19
1040 2000-07-07 Theodore Ts'o <tytso@valinux.com>
1042 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
1043 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
1044 list of filesystem flags supported by the library.
1046 2000-07-04 Theodore Ts'o <tytso@valinux.com>
1048 * ext2fs.h: Update to include latest journalling additions to the
1051 * dll/jump.funcs: Add new jumptable entries for
1052 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1053 ext2fs_badblocks_equal.
1055 * tst_badblocks.c: Update test program to test
1056 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
1058 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
1059 writes out bad blocks list to a file.
1061 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
1062 changes the callback function to take two additional
1063 arguments; a private blind pointer supplied by the caller,
1064 and pointer to a char * containing a pointer to the
1067 * badblocks.c (ext2fs_badblocks_equal): Add new function which
1068 returns true if two badblocks list are equal.
1070 * Makefile.in: Remove explicit link of -lc in the shared library.
1071 (It shouldn't be necessary, and is harmful in some cases).
1073 2000-06-10 Theodore Ts'o <tytso@valinux.com>
1075 * getsize.c (main): Add debugging code under #ifdef DEBUG
1077 2000-05-27 Theodore Ts'o <tytso@valinux.com>
1079 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
1080 earlier, so that if there's an error reading it, we can
1081 more cleanly back out of the operation.
1083 2000-05-25 <tytso@snap.thunk.org>
1085 * getsize.c (ext2fs_get_device_size): Use open64() instead of
1086 open() if it exists. Under linux, manually define the
1087 ioctl for BLKGETSIZE if it isn't already defined and it's
1090 * unix_io.c (unix_open): Use open64() instead of open() if it
1093 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1094 available (and prototypes are defined) use it in
1095 preference to llseek.
1097 * Makefile: Add hack dependency rule so that parallel makes work
1100 2000-05-18 Theodore Ts'o <tytso@valinux.com>

1104 2000-04-03 Theodore Ts'o <tytso@valinux.com>
1106 * block.c: Readibility tweak in conditionals involving
1109 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
1110 how to define __s64 and __u64. Turn off "compression is
1111 experimental" warning if the cpp macro
1112 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
1114 2000-02-11 <tytso@snap.thunk.org>
1116 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
1117 Conditionally include Compression as a supported type if
1118 ENABLE_COMPRESSION (via --enable-compression) is turned on.
1120 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
1122 2000-02-08 <tytso@snap.thunk.org>

1125 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1126 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
1127 Change to return the previous state of the bit that is
1128 being marked or unmarked. For speed optimization.
1130 2000-02-02 Theodore Ts'o <tytso@valinux.com>
1132 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
1134 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
1135 needed any more; we know it will always be i_generation.
1136 Add support for swapping the high bits of the uid and gid.
1138 1999-11-19 <tytso@valinux.com>
1140 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1141 counts if the link was successful. Patch suggested by

1145 the source directory.
1147 1999-11-10 <tytso@valinux.com>
1149 * Release of E2fsprogs 1.18
1151 1999-11-08 <tytso@valinux.com>
1153 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1154 since ext2fs_badblocks_list_free was moved to freefs.c.
1156 * tst_badblocks.c: Use the newer badblocks API names. Add
1157 duplicate blocks to the test inputs to test dealing with
1158 adding blocks which are already in the badblocks list.
1160 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1161 of the list, use a shortcut O(1) operations instead of an
1162 O(n) operation. (Idea suggested by David Beattie.)
1164 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1165 of badblocks_list_free(), to save a procedure call.
1167 1999-10-26 <tytso@valinux.com>
1169 * Release of E2fsprogs 1.17
1171 1999-10-26 <tytso@valinux.com>
1173 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1174 seem to handle ~0UL the same way as they used to.
1176 1999-10-25 <tytso@valinux.com>
1178 * nt_io.c (_OpenNtName): Open the device using
1179 FILE_SYNCHRONOUS_IO_NONALERT instead of
1180 FILE_SYNCHRONOUS_IO_ALERT
1181 (nt_open): At the end of the device open routine, unlock
1182 the drive but do not dismount it.
1184 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to

1191 1999-10-22 <tytso@valinux.com>
1193 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1195 * link.c (ext2fs_link): This call now uses the low three bits of
1196 the flags parameter to pass the directory filetype
1197 information; it will set the directory entry FILETYPE
1198 information if the filesystem supports it.
1200 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1201 option is set, then create the '.' and '..' entries with
1202 the filetype set to EXT2_FT_DIR.
1204 1999-09-24 <tytso@valinux.com>
1206 * nt_io.c: New file which supports I/O under Windows NT.
1208 1999-09-07 <tytso@valinux.com>
1210 * ext2fs.h: Add new fields for journalling and define new
1211 feature bits used by newer filesystems: IMAGIC_INODES,
1212 HAS_JOURNAL, RECOVER.
1214 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1215 we update the inode block count and size files so that the
1216 block count field is updated correctly when we create an
1219 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1221 * Release of E2fsprogs 1.15
1223 1999-06-23 <tytso@valinux.com>
1225 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1226 kernels that use i_generation instead of i_version. Patch
1227 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1229 1999-06-21 <tytso@valinux.com>
1231 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1232 directory entry before calling the callback function.
1233 This should prevent some core dumps of insufficiently
1234 paranoid callback functions.
1236 1999-05-29 <tytso@rsts-11.mit.edu>
1238 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1240 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1241 that we don't handle writing yet (we do). Fixed bug where
1242 we weren't allocating a big enough buffer for ext2_bmap.
1244 1999-05-03 <tytso@rsts-11.mit.edu>
1246 * openfs.c (ext2fs_open): Check to make sure that the number of
1247 blocks per group is not zero --- if so, it must be a bad
1250 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1252 * Release of E2fsprogs 1.14
1254 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1256 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1257 the inode number is zero; if it's zero, return
1258 EXT2_ET_BAD_INODE_NUM.
1260 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1262 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1263 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1266 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1268 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1269 non-Linux case to use EINVAL by default, unless it isn't
1270 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1273 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1275 * Release of E2fsprogs 1.13
1277 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1279 * Makefile.in: Updated dependencies.
1281 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1283 * initialize.c (ext2fs_initialize): Make sure that we allocate
1284 enough inodes so that we can make a valid filesystem.
1286 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1288 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1290 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1291 function declaration.
1293 * dblist.c (make_dblist): Add safety check in case the dblist
1294 pointer passed in is null (in which case, assign it to
1295 fs->dblist). Fixed some signed/unsigned warnings.
1297 * bmap.c: Make addr_per_block be of type blk_t to avoid
1298 signed/unsigned warnings.
1300 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1301 function declaration.
1303 * get_pathname.c (get_pathname_proc): Use return value from
1304 ext2fs_get_mem, instead of checking if &gp->name is
1307 * dir_iterate.c (ext2fs_process_dir_block):
1308 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1309 from the function declaration.
1311 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1312 return the error directly instead of jumping to the
1313 cleanup routine, since we don't need to do any cleanup.
1315 * alloc_table.c (ext2fs_allocate_group_table): Make this
1316 function take a dgrp_t for its group argument.
1318 * ext2fs.h: Make dgrp_t an __u32 type, and make
1319 fs->desc_group_count be of type dgrp_t.
1321 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1323 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1324 than 10 blocks when we need to expand the size of the
1327 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1329 * Release of E2fsprogs 1.12
1331 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1333 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1334 appropriate for all of the block group copies, so that
1335 it's clear where the beginning of the filesystem is on the
1336 disk. (For when the partition table gets scrod.)
1338 * ext2fs.h: Change the name of the feature from
1339 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1340 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1342 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1344 * inode.c (get_next_blockgroup): Fix bug where if
1345 get_next_blockgroup() is called early because of a missing
1346 inode table in a block group, the current_inode counter
1347 wasn't incremented correctly.
1349 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1351 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1352 against a completely trashed bad block inode.
1354 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1356 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1357 the stride length hits a bad value, we retry the block
1358 allocation starting at the beginning of the block group.
1360 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1361 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1362 e2_blkcnt_t to avoid collision with LFS API.
1364 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1366 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1367 way that avoids overflows on disk sizes greater than 4GB.
1369 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1371 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1372 return type for comparison functions for qsort.
1374 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1377 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1379 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1382 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1383 evade a potential problem with glibc's header files trying
1384 to spike out linux/types.h.
1386 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1387 include the old size of the memory, which is needed for
1388 some braindamaged memory allocation systems that don't
1391 * badblocks.c (ext2fs_badblocks_list_add):
1392 bb_inode.c (clear_bad_block_proc):

1396 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1397 pass the old size of the memory to be resized to
1398 ext2fs_resize_mem().
1400 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1402 * Makefile.in: Change to use new installation directory variables
1403 convention. Fix uninstall rules to take $(DESTDIR) into
1406 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1408 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1409 with 32 bit longs, then we need to manually define __s64
1410 and __u64, since the current kernel header files don't
1411 define these if __STRICT_ANSI__ is defined. This is a
1412 problem if we are compiling with full GCC warnings, since
1413 we do need 64 bit support.
1415 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1416 since we're not using ext2fs_move_blocks() and there
1417 is some question as to its usefulness in its current
1420 * bmap.c (block_bmap): Remove unused function.
1422 * bmove.c (process_block): Fix -Wall warning.
1424 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1426 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1427 contain the offset into the inode.i_blocks array when
1428 ref_block is zero. Since we haven't done a formal
1429 release of e2fsprogs since block_iterate2 was first
1430 introduced, I removed block_iterate2, and renamed
1431 block_iterate3 to be block_iterate2.
1433 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1434 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1435 use of block_iterate and block_iterate2 to
1436 block_iterate2 with the new prototype for the
1437 interator function. (using blkcnt_t forr blockcount)
1439 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1441 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1442 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1443 conditional defines of new features COMPAT_DIR_PREALLOC,
1444 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1445 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1446 the library to declare that we support COMPAT_DIR_PREALLOC,
1447 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1449 * fileio.c: Rename function ext2fs_file_llseek to be
1450 ext2fs_file_lseek, which is more accurate.
1452 * block.c: Add new function ext2fs_block_iterate3 which calls
1453 the iterator function with the blockcount argument of
1454 type blkcnt_t. This version of the function is
1455 allowed to handle large files; the other fucntions are
1458 * ext2fs.h: Add new type blkcnt_t
1460 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1462 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1463 field wasn't getting correctly incremented for sparse
1464 files when the indirect or doubly-indirect block
1465 specified in the inode was zero.
1467 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1469 * unlink.c (unlink_proc):
1470 * lookup.c (lookup_proc):
1471 * link.c (link_proc):
1472 * get_pathname.c (get_pathname_proc):
1473 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1474 from dirent->name_len, so it can be used for other
1477 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1478 and indicate that we have support for this incompatible
1481 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1483 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
1485 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>

1488 number of directories when the block group information is
1491 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1493 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1494 inode table is missing so that we catch the case where the
1495 first block group is missing.
1497 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1500 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1502 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1504 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1506 * test_io.c (test_flush): Add a debugging printf when the flush
1509 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1510 read in, return right away.
1512 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1514 * bitops.h: Don't try to do i386 inline asm functions if the
1517 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1518 instead of linux/types.h, and e2_bitops.h instead of
1521 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1524 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1526 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1527 so that we don't need to call get_next_blockgroup() the
1528 first time around. Saves a bit of time, and prevents us
1529 from needing to assign -1 to current_group (which is an
1532 * icount.c (insert_icount_el): Cast the estimated number of inodes
1533 from a float to an ino_t.
1535 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

1545 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1546 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is

1555 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
1556 make sure the contents of the disk are flushed to disk.
1558 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1572 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1574 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1575 paranoid about validating the directory counts from the
1576 block group information.
1578 * all files: Don't include stdlib.h anymore; include it in
1579 ext2_fs.h, since that file requires stdlib.h
1581 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1583 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1584 bitmap is loaded, and return an error if it is not.
1585 (expand_dir_proc): Only use ext2fs_write_dir_block when

1606 * bitops.c (ext2fs_warn_bitmap, ext2fs_warn_bitmap2): Don't call
1607 com_err if OMIT_COM_ERR is defined.
1609 Thu Oct 30 11:33:57 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1611 * Rename new error codes to _ET_ in them for consistency.
1613 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1615 * [all files, basically]: Added definition of ext2fs_get_mem,
1616 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1617 changed all library routines to use these wrapper functions.
1619 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
1620 instead of the system error messages.
1622 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
1625 * ext2fs.h: Added function declarations and constants for bmap.c
1628 * ext2_err.et.in: Added new error messages EXT2_FILE_RO and
1629 EXT2_ET_MAGIC_EXT2_FILE
1631 * Makefile.in: Added files bmap.c and fileio.c, and temporarily
1632 commented out brel_ma.c and irel_ma.c
1634 * bmap.c: New file which maps a file's logical block number to its
1635 physical block number.
1637 * fileio.c: New file which implements simple file reading and
1640 * alloc.c (ext2fs_alloc_block): New function which allocates a
1641 block, zeros it, and updates the filesystem accounting
1642 records appropriately.
1644 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1646 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
1647 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
1648 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
1650 * Change various library files to use these functions instead of
1651 EINVAL, ENOENT, etc.
1653 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1655 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
1656 need to declare llseek().
1658 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1660 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1662 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
1664 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1698 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1700 * io.h: Change the prototype of ext2fs_llseek() to use int's
1701 instead of unsigned int's.
1703 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1704 to make life easer for GNU Libc 2.
1706 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1707 filesystem has its bitmaps stored as 32-bit words with bit
1708 0 as the LSB of each word. Thus a bitmap with only bit 0
1709 set would be, as a string of bytes, 00 00 00 01 00 ... To
1710 cope with this, we byte-reverse each word of a bitmap if
1711 we have a big-endian filesystem, that is, if we are *not*
1712 byte-swapping other word-sized numbers.
1714 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1732 and size_t where appropriate.
1734 * closefs.c (ext2fs_flush): Use dgrp_t instead of int where
1737 * openfs.c (ext2fs_open):
1738 * check_desc.c (ext2fs_check_desc): Use blk_t instead of int where
1741 * rw_bitmaps.c (read_bitmaps):

1744 * initialize.c (ext2fs_initialize):
1745 * brel_ma.c: Fix to make be 16-bit safe.
1747 * link.c (ext2fs_link):
1748 * unlink.c (ext2fs_unlink):

1761 * bb_inode.c (set_bad_block_proc): Add #pragma argsused for Turbo C.
1763 * alloc.c (ext2fs_new_inode): Use ino_t instead of int for the
1766 * get_pathname.c: Use ino_t instead of int where appropriate.
1768 * ext2fs.h: Make the magic structure element be errcode_t instead
1771 * alloc.c alloc_tables.c badblocks.c bb_compat.c bb_inode.c
1772 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
1773 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c
1774 dirblock.c dupfs.c expanddir.c freefs.c get_pathname.c
1775 icount.c initialize.c inline.c inode.c irel_ma.c link.c
1776 llseek.c lookup.c mkdir.c namei.c newdir.c read_bb.c
1777 read_bb_file.c rs_bitmap.c rw_bitmaps.c swapfs.c
1778 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
1779 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
1781 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1783 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1784 is zero, then return EXT2_IO_LLSEEK_FAILED.
1786 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1788 * Release of E2fsprogs 1.11
1790 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1792 * dblist.c (ext2fs_dblist_count): Added new function which returns
1793 the number of directory blocks in dblist.
1795 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1797 * unix_io.c (unix_flush): Make the io_channel flush function do a
1798 fsync to flush the kernel buffers to disk.
1800 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1802 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1803 current inode number wasn't being set by the
1804 goto_blockgroup function.
1806 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1808 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1809 of blocks which need to be moved, and moves those blocks
1810 to another location in the filesystem.
1812 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1813 bitmap, make sure all of the new parts of the bitmap are
1816 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1818 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1819 wasn't being returned to the caller.
1821 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1822 ext2fs_allocate_group_table() which sets the group tables
1823 for a particular block group. The relevant code was
1824 factored out of ext2fs_allocate_tables().
1826 * dblist.c (make_dblist): Adjust the initial size of the directory
1827 block list to be a bit more realistic (ten plus twice the
1828 number of directories in the filesystem).
1830 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1832 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1833 ext2fs_badblocks_list_test would test the list (and exceed
1834 array boundaries) if there were no bad blocks on the bad
1835 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1837 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1839 * Release of E2fsprogs version 1.10
1841 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1843 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1844 inode and block bitmaps based on the RAID 0 stride
1845 parameter (which is passed by mke2fs).
1847 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1848 mke2fs to communicate the stride length to
1849 ext2fs_allocate_tables()
1851 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1853 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1854 systems. (We can't assume that the new filesystem types
1857 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1859 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1860 allocate the inode and block bitmaps inside block group at
1863 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1865 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1866 filesystem has no free blocks, ext2fs_new_block would loop
1869 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1871 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1872 free if refcount goes to zero.
1874 * inode.c (create_icache): Initialize refcount to 1.
1876 * ext2fsP.h: Added refcount to ext2_inode_cache
1878 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
1881 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1882 badblocks structure.
1884 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1886 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
1888 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1890 (unix_close, test_close): Decrement the refcount and only
1891 close the io_channel if the refcount goes to 0.
1893 * io.h: Add refcount to the io_channel structure. Add new macro
1894 interface io_channel_bumpcount() to bump the refcount.
1896 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1898 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1899 cache in the filesystem handle, instead of the inode cache
1900 in a static variable.
1902 * freefs.c: Added static function to free the inode cache (called by
1905 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1907 * ext2fs.h: Added pointer to the inode_cache structure.
1909 * block.c (block_iterate_ind, block_iterate_dind,
1910 block_iterate_tind): If there are holes in the indirect,
1911 doubly indirect, or triply indirect blocks, increment the
1912 block count field automatically.
1914 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1916 * Release of E2fsprogs version 1.09
1918 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1920 * version.c (ext2fs_parse_version_string): Check the passed in
1921 version string (instead of the hard-coded one).
1923 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1924 greater filesystem size, clamp it to prevent allocating a
1925 block or inode bitmap beyond the filesystem.
1927 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1928 overhead calculation was accidentally removed.
1930 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1932 * Release of E2fsprogs version 1.08
1934 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1936 * dblist.c (ext2fs_set_dir_block): New function which sets the
1937 block of a dblist entry, given the directory inode and
1940 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1942 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1943 inode bitmaps at staggered locations across the block
1944 groups, to avoid concentrating the bitmaps on a small
1945 number of disks when using striped RAID arrays.
1947 * initialize.c (ext2fs_initialize): By default, choose the maximum
1948 possible number of blocks per group (based on the size of
1949 the bitmaps in the blocksize).
1951 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1953 * initialize.c (ext2fs_initialize): Add support for
1954 EXT2_COMPAT_SPARSE_SUPER feature.
1956 * closefs.c (ext2fs_bg_has_super): New function to determine
1957 whether or a particular block group should have a
1958 superblock and block group descriptor. Used for the
1959 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1960 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1961 or not the superblock should be written out for the block
1964 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1965 for sparse duplicate superblocks.
1967 * version.c (ext2fs_get_library_version): New function which
1968 returns the library version.
1970 * version.c (ext2fs_parse_version_string): New function which
1971 parses a version string and returns a version number,
1972 so application programs can compare version numbers as
1975 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1977 * icount.c (ext2fs_create_icount): Change function so that it also
1978 takes a new argument which contains a "hint" icount
1979 structure. This "hint" icount allows the create function
1980 to set up the sorted list in advance. This reduces
1981 significantly the amount of data moving needed to insert
1982 these inodes into the list later.
1984 * icount.c (ext2fs_icount_validate): New function which validates
1985 that the icount structure's rep invariant.
1987 * icount.c (get_icount_el): Completely revamped implementation
1988 to subsume put_icount_el(). Put_icount_el() used to
1989 use an O(N) implementation to insert in the middle
1990 of the icount list. It now uses a O(ln N) to search
1991 for where the icount should be inserted, and then uses
1992 a memcpy to move the list down (instead of a for loop).
1994 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1995 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1996 to see if the inode is within bounds; if it isn't, return
1999 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
2000 when a bad inode number is passed to test_generic_bitmap
2001 to be EXT2FS_TEST_ERROR instead of the wrong
2002 EXT2FS_UNMARK_ERROR.
2004 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
2006 * Release of E2fsprogs version 1.07
2008 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2010 * Makefile.in (ELF_VERSION): Change version to be 2.2
2012 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2014 * alloc.c (ext2fs_get_free_blocks): Change routine to use
2015 ext2fs_fast_test_block_bitmap_range().
2017 * bitops.h (ext2fs_fast_test_block_bitmap_range,
2018 ext2fs_test_block_bitmap_range: New inline functions which
2019 test to see whether a contiguous range of blocks is
2022 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2024 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
2025 use ext2fs_badblocks_* instead of badblocks_*
2027 * bb_compat.c: New file which translates between old badblocks_*()
2028 names to ext2fs_badblocks_*()
2030 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
2031 link.c (since e2fsck doesn't use ext2fs_unlink()).
2033 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
2034 bitmap resizing routine moved from bitmaps.c, since e2fsck
2035 doesn't need to use this function.
2037 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
2038 since e2fsck only needs ext2fs_lookup.
2040 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2042 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
2043 already set; this is needed so that programs like dump
2044 which use the inode scan functions will deal with
2045 filesystems that have bad blocks in the inode table.
2047 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2049 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
2050 Moved to ext2fsP.h, since it doesn't need to be part of
2051 the public interface.
2053 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
2055 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2057 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
2058 directory block list abstraction. (Code moved from
2061 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
2062 to inode.c (since no one else should be peeking inside it!)
2064 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
2066 * openfs.c (ext2fs_open): Check the feature set in the ext2
2067 superblock, and refuse to open filesystems if they contain
2068 incompatible features. (Can be overriden with the
2071 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2073 * block.c (ext2fs_block_iterate2): Added new function
2074 ext2fs_block_iterate2 which changes the function
2075 signature of the callback function to include the
2076 referencing block and offset.
2078 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
2079 ext2fs_inode_scan_goto_blockgroup which allows an
2080 application to jump to a particular block group while
2081 doing an inode scan.
2083 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2085 * dirblock.c: Include string.h, since we use memcpy().
2087 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2089 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2090 a long not an int; this doesn't matter on i386 machines,
2091 but it does on Alpha's.
2093 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2095 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2096 table pointer is NULL, then return an error indicating
2097 that the inode table is missing.
2098 (get_next_blockgroup, get_next_blocks,
2099 ext2fs_get_next_inode): Don't treat a missing inode table
2100 as permanent error. Return MISSING_INODE_TABLE, but as an
2101 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
2103 * rw_bitmaps.c (ext2fs_write_block_bitmap,
2104 ext2fs_write_inode_bitmap): If the inode or block bitmap
2105 block is zero, then don't write out the inode or block
2106 bitmap. The idea here is to avoid stomping on the
2108 (read_bitmaps): If the inode or block bitmap block is
2109 zero, then fill in that portion of the inode or block
2110 bitmap with all zeros.
2112 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
2113 blocks in inode table when the inode table size is
2114 non-standard (and can therefore span blocks).
2116 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2118 * alloc.c (ext2fs_new_block): Fix fencepost error in

2122 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2124 * inode.c (check_for_inode_bad_blocks): New function called by
2125 get_next_blocks() to avoid reading in bad blocks marked in
2126 fs->badblocks. Inodes located in bad blocks are returned
2127 by ext2fs_get_next_inode() returns the error code
2128 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
2130 * alloc_tables.c (ext2fs_allocate_tables): New function which
2131 performs the part of mke2fs's job of allocating the

2146 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2147 blocks to the badblock list in sorted order. This allows
2148 badblocks_list_test to be coded using a binary search for
2151 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2153 * Release of E2fsprogs version 1.06
2155 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2158 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2161 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2162 set, then only write out the master superblock.
2164 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2166 * block.c (ext2fs_block_iterate): Fixed bug which caused
2167 block_iterate to fail to handle HURD created filesystems;
2168 it tested the inode translator field before the inode was

2190 symbolic link (if any) at the target.
2192 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2194 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2195 for shortcut function fs->read_inode() and fs->write_inode().

2202 * namei.c (ext2fs_follow_link): New function.
2203 (ext2fs_namei): Extended to have support for chasing
2204 symbolic links. ext2fs_namei() still returns an inode
2205 which is a symbolic link. Symbolic links are only chased
2206 while resolving the containing directory. To chase
2207 symbolic links of the final result, use
2208 ext2fs_follow_link().
2210 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2212 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.

2219 * initialize.c (ext2fs_initialize): On systems where the byte
2220 order is not i386 compatible, set the swap_byte flag.
2222 * inode.c (inocpy_with_swap): Check to see if inode contains a
2223 fast symlink before swapping the inode block fields. This
2224 required adding a new argument to inocpy_with_swap to
2225 determine whether the mode field is in host order or not.
2227 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2229 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2230 the sparc, if EXT2_STD_BITOPS set, use the standard
2231 i386-compatible bitmask operations, instead on the
2232 non-standard native bitmask operators.

2236 * block.c (ext2fs_block_iterate): Cause block iterator to return
2237 the HURD translator block (along with everything else).
2238 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2239 iterator, then don't return any meta data blocks
2240 (including the HURD translator).
2242 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2244 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2246 * uuid.c: New file, containing UUID utility functions.
2248 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2250 * ext2fs.h: Add a definition of the "real" ext2 superblock.

2254 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
2256 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2258 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2259 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2260 that's a basic value that must be correct for the rest of
2261 the library to work.
2263 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2266 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2277 Change the m68k bit numbering for bitmasks to match with
2278 the bit numbering used by all other ext2 implementations.
2280 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
2282 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
2283 ext2fs_open_inode_scan): Support dynamically-sized inodes.
2285 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>

2315 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2316 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2317 to avoid conflicts with with kernel include files. Also
2318 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2321 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2323 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c

2343 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2346 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2348 * unix_io.c (unix_open): Add a double check; if the passed in name
2349 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2351 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2353 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

2360 * getsize.c (ext2fs_get_device_size): Add support for reading the
2361 partition size from a BSD disk label.
2363 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2365 * getsize.c (ext2fs_get_device_size): New function that determins

2375 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2376 Move these functions to freefs.c.
2378 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2379 descriptors shadow memory to keep purify quiet. (This
2380 also has the nice benefit that the unused portion of the
2381 shadow descriptors are zeroed out.)
2383 * dirblock.c (ext2fs_write_dir_block): We need to use
2384 dirent->rec_len *before* it's byteswapped to find the
2385 location of the next directory structure!
2387 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2388 cause ext2fs_new_inode to loop infinitely if we're trying
2389 to allocate an inode in group #0 and there are no free
2390 inodes at all in the system.
2392 * closefs.c: #include <errno.h> if it exists.
2394 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2396 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2413 file containing functions for reading and writing
2414 directory blocks (byte swapping if necesssary)
2416 * block.c (block_iterate_ind, block_iterate_dind,
2417 block_iterate_tind): Byte swap the block addresses if

2423 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2425 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2426 the superblock and group descriptors before writing it out.
2428 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2429 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2430 and group descriptors.
2432 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2433 to desp ext2 filesystem structures.
2435 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2436 supplied by Pete A. Zaitcev so that the C language
2437 versions of these functions are more portable. They will
2438 now work on both little and big endian systems, and the
2439 assumption that 32-bit integers are used is gone.
2441 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2442 doing byte swapping.
2444 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2445 byte swapping should take place.
2447 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

2458 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2459 if the magic number is correct, it will be allocated.
2461 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2463 * block.c (block_iterate_ind, block_iterate_dind,
2464 block_iterate_tind): Don't recompute block_nr each loop;
2465 just increment it! Factor check of BLOCK_FLAG_APPEND out
2466 of the loop. Factor mask of BLOCK_CHANGED into changed
2467 variable out of the loop. (block_iterate_ind, in
2468 particular, gets called a lot, so every little
2469 optimization helps.)
2471 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2473 * block.c (block_iterate_ind, block_iterate_dind,

2480 ext2fs_fast_test_inode_bitmap): Add fast version of these
2481 functions, which don't do range checking.

2485 ext2fs_get_inode_bitmap_end): Add new accessor functions
2486 which return the start and end points of the bitmaps.
2488 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2490 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2491 instead of llseek. The errno if the offset is too large
2492 and lseek is not supported should be EINVAL, not -EINVAL.
2494 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2496 * Makefile.in: Added support for ELF shared libraries.
2497 Fixed typos in the compilation rules.
2498 (distclean): Added Makefile.
2500 * llseek.c (llseek): New function, if llseek() does not exist in the

2512 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2513 the S_*, which are normally defined in <sys/stat.h>. This
2514 allows us to compile e2fsprogs on a non-Linux system,
2515 which may have a different value for S_IFDIR.
2517 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2519 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2520 this is a user-mode application!
2522 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2524 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2525 __linux__ so that non-linux systems won't see it.
2527 * alloc.c: Include <errno.h> if possible.
2528 * badblocks.c: Ditto.
2529 * bb_inode.c: Ditto.
2532 * expanddir.c: Ditto.

2545 support separate compilation directories.
2547 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2549 * initialize.c (ext2fs_initialize): Don't allow more than one
2550 bitmaps's worth of inodes in a group.
2552 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2554 * llseek.c (ext2_llseek): Added error checking to the llseek()
2555 compat code to protect against overflow. This only
2556 applies to 1.0 and early 1.1 kernels, which don't support
2557 the llseek() system call.
2559 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2561 * unix_io.c (unix_open): Initialize the read_error and write_error
2562 io_channel pointers to be null.
2564 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2565 found, clear it but don't try to update the filesystem
2566 accounting information, since that's hopeless anyway.
2568 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2569 bloblock_iterate_tind): Check to see if the indirect blocks are
2570 valid before trying to read them.

2576 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2577 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2578 illegal block or inode number is passed in, return instead
2579 of trying to test, set, or clear the bit.
2581 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2583 * Makefile: Added a dummy install target in case shared libraries

2597 the inode and block bitmaps.
2599 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2600 magic number for a block bitmap instead of an inode bitmap.
2602 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
2603 magic number checking for the inode_scan structure.

2617 * openfs.c (ext2fs_open): Add check for io_manager structure's
2620 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2621 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2622 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2623 * read_bb.c (ext2fs_read_bb_inode):
2624 * read_bb_file.c (ext2fs_read_bb_FILE):
2625 * newdir.c (ext2fs_new_dir_block):
2626 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
2627 * link.c (ext2fs_link, ext2fs_unlink):
2628 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
2629 ext2fs_write_inode, ext2fs_get_blocks,
2630 ext2fs_check_directory):
2631 * get_pathname.c (ext2fs_get_pathname):
2632 * expanddir.c (ext2fs_expand_dir):
2633 * block.c (ext2fs_block_iterate):
2634 * bitmaps.c (ext2fs_allocate_inode_bitmap,
2635 ext2fs_allocate_block_bitmap):
2636 * bb_inode.c (ext2fs_update_bb_inode):
2637 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
2638 * check_desc.c (ext2fs_check_desc):
2639 * closefs.c (ext2fs_close, ext2fs_flush):
2640 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2645 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2646 openfs.c into its own file.
2648 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2649 structure magic numbers.
2651 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2652 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2653 someone uses the -b option to specify the use of the backup
2654 superblock --- this usually means that the main superblock is
2658 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2659 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2660 revision level to the superblock.
2662 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2669 * initialize.c: Completely revamped the inode and block bitmap
2670 structures, so that they can be better chance of being extensible
2671 in a shared library. They are now their own type, instead of
2672 being a char *. Also, the function signatures of
2673 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2674 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2675 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2676 changed to eliminate the ext2_filsys argument, since it is no
2679 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2681 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2682 system call if available.
2684 * llseek.c: new file. This is the stub calling the llseek system
2685 call which allows supports for 2GB+ file systems.
2687 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2688 the creator operating system.
2690 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2692 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2693 the group descriptor statistics in addition to everything else.
2694 This relieves mke2fs of the responsibility of doing it.
2696 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2697 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2698 not the generic C function equivalents should be included or not.
2700 * openfs.c (ext2fs_open): If a superblock is specified, then use
2701 the backup group descriptors that go along with this superblock,
2702 instead of using the primary group descriptors. This allows
2703 e2fsck to recover filesystems where the primary group descriptors
