1 2002-11-09 Theodore Ts'o <tytso@mit.edu>
3 * Release of E2fsprogs 1.32
5 2002-11-09 Theodore Ts'o <tytso@mit.edu>
7 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
8 unix_write_blk): Optimize routines so that we don't end up
9 searching the cache twice when a block isn't in the
10 cache. If reads are larger than READ_DIRECT_SIZE, don't
11 let them go through the cache.
13 * unix_io.c (find_cached_block): Fixed bug which caused some clean
14 blocks to be erroneously marked as dirty, so they would
15 get written back to the disk before they are evicted from
16 the cache. Harmless, but it slows down e2fsck
19 2002-11-08 Theodore Ts'o <tytso@mit.edu>
21 * Release of E2fsprogs 1.31
23 2002-11-08 <tytso@snap.thunk.org>
25 * Makefile.in (check): Skip trying to compile test_byteswap
26 if --disable-byteswaap had been given to configure.
28 2002-11-07 <tytso@snap.thunk.org>
30 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
31 support when the MASTER_SB_ONLY flag is set. Some of
32 the descriptor blocks that should have been written out
35 2002-10-31 Theodore Ts'o <tytso@mit.edu>
37 * Release of E2fsprogs 1.30
39 2002-10-31 Theodore Ts'o <tytso@mit.edu>
41 * ext2_fs.h: Add support for a new inode flag, which is to be used
42 for indicating the top of directory hierarchies for the
43 Orlov block allocator.
45 * ismounted.c (check_mntent, check_mntent_file): Add better
46 support for loopback-mounted filesystems. Check /etc/mtab
47 if /proc/mounts doesn't turn up any mount flags, since
48 /etc/mtab has the loopback image filename, instead of
49 /dev/loop0. Also, check based on st_dev and st_ino, so
50 that if a relative pathname or a pathnames using symbolic
51 links are used, we can detect the the filesystem correctly
52 in those cases. (Addresses Sourceforge bug #619119)
54 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
55 don't try the FDFLUSH ioctl that was required for floppies
56 with older kernels. This avoids needless whining from the
57 MD device driver. (Addresses Sourceforge bug #545832).
59 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
60 wrong group_block to ext2fs_descriptor_block_loc if we're
61 using the backup superblock/block group descriptors.
62 (ext2fs_descriptor_block_loc): If we're using the backup
63 superblock descriptors, use the backup descriptor block in
66 2002-10-30 Theodore Ts'o <tytso@mit.edu>
68 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
69 table so that it buts up against the bitmap blocks, to
70 avoid block fragmentation.
72 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
73 bug; only allocate group descriptor blocks up to
76 2002-10-25 Theodore Ts'o <tytso@mit.edu>
78 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
79 know when a filesystem was created. (Sometimes this can
82 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
84 2002-10-20 Theodore Ts'o <tytso@valinux.com>
86 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
87 the journal data mode.
89 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
90 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
91 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
92 the meta_blockgroup filesystem format.
94 2002-10-15 <tytso@snap.thunk.org>
96 * ext2_fs.h: Add new field in superblock for default mount options.
98 2002-10-13 Theodore Ts'o <tytso@mit.edu>
100 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
103 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
105 * rw_bitmaps.c (ext2fs_write_block_bitmap,
106 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
107 because the bitmap is getting written to disk. Make
108 ext2fs_swap_bitmap be a static function, since it's not
109 intended to be exported.
111 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
113 2001-09-24 Theodore Tso <tytso@mit.edu>
115 * Release of E2fsprogs 1.29
117 2001-08-31 Theodore Tso <tytso@thunk.org>
119 * Release of E2fsprogs 1.28
121 2002-08-31 Theodore Ts'o <tytso@valinux.com>
123 * dblist.c (ext2fs_dblist_sort): New function which allows the
124 caller to pass in a special sort comparison function.
126 2002-08-20 Theodore Ts'o <tytso@mit.edu>
128 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
129 failed to accurately characterize non-standard slow
130 symlinks. (Which don't appear in practice on real-life
131 systems, fortunately.)
133 2002-08-17 Theodore Ts'o <tytso@mit.edu>
135 * Makefile.in: Remove inode_io.o from the standard object files,
136 and only build it if debugfs is enabled (it requires
137 fileio.o, which is only built if --disable-debugfs isn't
138 specified to configure).
140 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
141 incompatible way so that it is no longer
142 endian-dependent. Add the TEA hash. Allow the seed
143 parameter to be optional.
145 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
146 These features are all now in the HALF_MD4 hash. Add
147 definition for EXT2_HASH_TEA.
149 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
150 a pointer instead of an array.
152 2002-08-16 Theodore Ts'o <tytso@mit.edu>
154 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
156 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
157 the number of data blocks used by an inode exclusive of
160 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
161 adjusts the reference count in an extended attribute block.
163 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
164 correctly deal with extended attribute blocks in symbolic
167 2002-08-13 <tytso@snap.thunk.org>
169 * Makefile.in: Move dupfs.o and test_io.o from the
170 needed-by-debugfs object list to the needed-by-resizer
171 object list. Fixes compile problem if the system is built
172 with only --disable-debugfs.
174 2002-07-29 Theodore Ts'o <tytso@mit.edu>
176 * link.c (ext2fs_link): When adding a new link to a directory,
179 2002-07-23 Theodore Ts'o <tytso@mit.edu>
181 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
182 calculations for names > 32 characters to be completely
183 bogus. Changed MD4 calculation to match what is currently
184 being used in the CVS gkernel tree.
186 2002-07-19 Theodore Ts'o <tytso@mit.edu>
188 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
189 superblock definition.
191 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
192 create a set of u32_list functions.
194 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
195 since that's required by the directory indexing code.
197 2002-07-14 Theodore Ts'o <tytso@mit.edu>
199 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
200 using a C++ reserved word.
202 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
203 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
204 old version of glibc (built against 2.2 headers) will
205 interact badly with the workaround to actually cause more
206 problems. I hate it when the glibc folks think they're
207 being smarter than the kernel....
209 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
211 * ext2_fs.h: Add superblock field for reserved group descriptors.
213 2002-06-28 Theodore Ts'o <tytso@mit.edu>
215 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
216 ext2fs_cpu_to_{l,b}e{32,16}
218 2002-06-27 Theodore Ts'o <tytso@mit.edu>
220 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
221 Add appropriate fallbacks in this case.
223 2002-06-26 Theodore Ts'o <tytso@mit.edu>
225 * dirhash.c (ext2fs_dirhash): Change function signature to support
226 a hash seed, and to return the minor hash (for 64-bit hash
227 support). Add support for the half MD4, half MD4 with
228 seed, and half MD4 with seed and 64 bits.
230 2002-06-15 Theodore Ts'o <tytso@mit.edu>
232 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
234 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
236 * ext2_fs.h: Add macros for maximum block/inode counts:
237 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
238 and EXT2_MAX_INODES_PER_GROUP.
240 * openfs.c (ext2fs_open): Check that the number of blocks in a group
241 is less than 2^16, otherwise we need an INCOMPAT flag (not
242 in existence yet, if ever) to open such a filesystem.
244 * initialize.c (ext2fs_initialize): Limit the number of blocks and
245 inodes in a group to less than 2^16.
247 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
249 * ext2_fs.h: Further minor cleanups of the header. Consolidate
250 some checks for __KERNEL__ into one place.
252 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
254 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
255 the EXT2_SB() macro instead. Remove kernel function
256 prototypes also. This matches the 2.5 kernel, and
257 is also cleaner for other reasons. Whitespace cleanup.
259 2002-05-21 Theodore Ts'o <tytso@mit.edu>
261 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
263 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
265 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
267 * initialize.c (ext2fs_initialize): Remove assumption that
268 blocksizes are always <= 4k.
270 2002-05-11 Theodore Ts'o <tytso@mit.edu>
272 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
273 silently if inode pointer is NULL (and ext2fs_bmap is
274 expected to read the inode itself).
276 2002-04-27 Theodore Ts'o <tytso@mit.edu>
278 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
279 file we are checking is a block device file before looking
280 at st_rdev, since it's not valid for normal files.
281 (is_swap_device): Move so that it is outside the
282 HAVE_MNTENT_H, so that it is always built.
284 2002-03-11 Theodore Tso <tytso@mit.edu>
286 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
287 functions which take an extra flags argument. The flag
288 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
289 field is byte swampped on big-endian machines, since in
290 the V2 structure, name_len is a char field which is
291 doesn't need to be byte swapped --- except if an
292 old-style kernel had byte-swapped the name_len field
293 as part of the V1 structure.
295 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
297 * dirhash.c (ext2fs_dirhash): New function which calculates the
298 hash for a filename in an indexed directory.
300 2002-03-08 Theodore Tso <tytso@mit.edu>
302 * Release of E2fsprogs 1.27
304 2002-03-07 Theodore Tso <tytso@mit.edu>
306 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
308 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
309 tst_byteswap.c: Fix gcc -Wall complaints
311 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
312 (From Philipp Thomas <pthomas@suse.de>)
314 2002-02-25 Theodore Tso <tytso@mit.edu>
316 * ext2_fs.h: Add structure definitions for the directory indexing
319 2002-02-23 Theodore Tso <tytso@mit.edu>
321 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
322 it doesn't break things on mis32, sparc32, and alpha
325 2002-02-21 Theodore Tso <tytso@mit.edu>
327 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
328 we were missing an fclose().
330 2002-02-20 Theodore Tso <tytso@mit.edu>
332 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
333 abstraction interface which exports an ext2 inode.
335 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
336 as a public interface. Change void * to const void * in
337 ext2fs_file_write's interface.
339 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
340 conditional; save a few bytes.
342 2002-02-12 Theodore Tso <tytso@mit.edu>
344 * Makefile.in (tst_badblocks): Add some extra .o files when
345 linking the debugging program tst_badblocks which are
346 needed if we aren't compiling with inline functions enable.
348 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
349 define away __inline__ since it may not be supported.
351 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
352 stripped down jbd_debug that doesn't use variadic
353 arguments. This will cause warnings under AIX, but things
356 2002-02-03 Theodore Tso <tytso@thunk.org>
358 * Release of E2fsprogs 1.26
360 2002-02-03 Theodore Tso <tytso@mit.edu>
362 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
363 so that the number of directories in use is adjusted
366 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
367 which optionally will modify the number of directories
370 2002-01-03 Theodore Tso <tytso@mit.edu>
372 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
373 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
374 which will return deleted directory entries.
375 ext2fs_dir_iterate2 takes a new callback function which
376 is identical with the one used by
377 ext2fs_dblist_dir_iterate(). If the directory entry is
378 deleted, the callback function will be called with the
379 entry paraemter set to DIRENT_DELETED_FILE.
381 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
382 ext2fs_block_alloc_stats): New functions which update
383 block/inode allocation statistics in the bitmaps, block
384 group descriptors, and superblock.
386 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
387 expanddir.c (expand_dir_proc), bb_inode.c
388 (clear_bad_block_proc, set_bad_block_proc,
389 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
390 Update to use new block/inode allocation statistics.
392 2001-12-24 Theodore Tso <tytso@mit.edu>
394 * ismounted.c (is_swap_device): New function used by
395 ext2fs_check_if_mounted and ext2fs_check_mount_point which
396 determines whether or not the specified device is a swap
397 device by using /proc/swaps. More bulletproofing for
398 idiotic/careless system administrators!
400 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
401 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
402 field to struct_ext2_filsys, umask. This field is
403 initialize to 022, and affects ext2fs_mkdir in the obvious
404 way. (In the future umask should also affect new file
405 creation routines, but the fileio functions don't
406 currently support this yes.)
408 * ismounted.c (check_mntent_file): Stat all of the entries in
409 /etc/mtab and/or /proc/mounts in order to catch dim-witted
410 system administrators who might have created alias
413 2001-12-23 Theodore Tso <tytso@mit.edu>
415 * Makefile.in, jfs_user.h: Move linux/jbd.h to
416 ext2fs/kernel-jbd.h, to avoid using the system header
417 file version of hbd.h when using diet glibc (since it
418 forcibly adds /usr/include to the beginning of the
419 include search path.)
421 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
422 include/linux directory.
424 2001-12-16 Theodore Tso <tytso@mit.edu>
426 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
427 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
428 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
430 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
433 2001-12-03 Theodore Tso <tytso@mit.edu>
435 * unix_io.c (unix_open): Make sure the ulimit workaround works
436 regardless of the version of glibc which is used to
439 2001-11-26 Theodore Tso <tytso@mit.edu>
441 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
442 trying to unset the filesize limit if at all possible,
443 if a block device is getting opened. (The filesize limit
444 shouldn't be applied against writes to a block device, but
445 starting in 2.4.10, the kernel is doing this.)
447 2001-11-05 Theodore Tso <tytso@mit.edu>
449 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
450 file on adding a journal to an already-mounted filesystem,
451 try to clear the ext2 file attributes on an already
452 existing .journal file so that we don't fail if on a
453 partially added journal to the filesystem.
455 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
456 which signals that a particular inode should not have the
457 last bits of data (the "tail") be merged with another
458 file. This is necessary to keep LILO happy.
460 2001-09-20 Theodore Tso <tytso@thunk.org>
462 * Release of E2fsprogs 1.25
464 2001-09-16 Theodore Tso <tytso@mit.edu>
466 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
467 which was breaking the build on the Hurd. (Addresses
470 2001-09-13 Theodore Ts'o <tytso@mit.edu>
472 * ismounted.c (check_mntent_file): We now validate the entry in
473 /etc/mtab to make sure the filesystem is really mounted,
474 since some broken distributions (read: Slackware) have
475 buggy boot scripts that don't initialize /etc/mtab before
476 checking non-root filesystems. (Slackware also doesn't
477 check the root filesystem separately, and reboot if the
478 root filesystem had changes applied to it, which is
479 dangerous and broken.)
481 2001-09-02 Theodore Tso <tytso@thunk.org>
483 * Release of E2fsprogs 1.24a
485 2001-08-30 Theodore Tso <tytso@thunk.org>
487 * Release of E2fsprogs 1.24
489 2001-08-30 Theodore Tso <tytso@valinux.com>
491 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
492 changes, since the ioctl number has been reused by another
495 2001-08-15 Theodore Tso <tytso@valinux.com>
497 * Release of E2fsprogs 1.23
499 2001-08-05 Theodore Tso <tytso@valinux.com>
501 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
502 version of the bitmap test routines to speed up these
503 routines. (At some point I may want to make these
504 routines use the find_first_bit functions, but that will
505 add a lot of complexity since it means that these
506 functions will have to break the bitmap abstraction
507 boundary. It's not clear it's worth it.)
509 * mkjournal.c (mkjournal_proc): Remember the last block allocated
510 to speed up ext2fs_new_block().
512 2001-07-29 Theodore Tso <tytso@valinux.com>
514 * finddev.c (scan_dir): Fix memory leak; we weren't calling
515 closedir() when exiting the function in all cases.
517 2001-07-27 Theodore Tso <tytso@valinux.com>
519 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
520 block usable in the journal for external journals to be 2
521 or 3, depending on the blocksize, so that the existing
522 kernel code does the right thing.
524 * getsize.c (ext2fs_get_device_size): Add support for the
525 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
526 from Ben LaHaise, but it's likely this interface won't
529 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
530 when writing the journal superblock, too. (Oops! Needed
531 to make 1k filesystems with external journal to work.)
533 2001-07-26 Theodore Tso <tytso@valinux.com>
535 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
536 to find the journal superblock if the blocksize is 1024.
538 2001-07-21 Theodore Tso <tytso@valinux.com>
540 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
542 2001-07-20 Theodore Tso <tytso@valinux.com>
544 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
545 attribute block, set the filesystem changed bit.
547 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
548 Comment out these functions since we're not using them.
550 2001-07-10 Theodore Tso <tytso@valinux.com>
552 * closefs.c (write_primary_superblock): After writing changes to
553 the primary superblock, update the original superblock
554 copy so we don't have to re-write those changes in the
556 (ext2fs_flush): Clear the superblock dirty flag after
557 we've flushed out changes to disk.
559 2001-07-07 Theodore Tso <tytso@valinux.com>
561 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
562 to avoid register conflicts when compiling in PIC mode.
564 2001-07-04 Theodore Tso <tytso@valinux.com>
566 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
567 Add new functions (C and in i386 assembler) which quickly
568 find bits set in a bitmask.
570 2001-06-23 Theodore Tso <tytso@valinux.com>
572 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
573 ext2_ext_attr.h and ext_attr.c for extended attributes
576 * Release of E2fsprogs 1.22
578 2001-06-22 Theodore Tso <tytso@valinux.com>
580 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
581 descriptor so that adding a journal to a mounted
582 filesystem doesn't die. (Fixes a bug accidentally
583 introduced in e2fsprogs 1.21.)
585 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
586 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
587 fchflags without defining UF_NODUMP. (Addresses Debian
590 * flushb.c: Use platform independent method of defining the
591 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
592 since on newer glibc's BLKFLSBUF is defined there.
594 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
595 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
596 to support byte swapping even if we don't support the
597 conversion functions. (Fixes Debian bug #101686).
599 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
600 since the byte-swapping code all assumes the
601 ext2_dir_entry structure. (It's a question of whether or
602 not name_len should be byte-swapped or not, and whether
603 it's a 16 bit or 8 bit field.)
605 2001-06-15 Theodore Tso <tytso@valinux.com>
607 * Release of E2fsprogs 1.21
609 2001-06-15 Theodore Tso <tytso@valinux.com>
611 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
612 file which is generated and is therefore found in the
613 build directory, not source directory.
615 * ismounted.c (check_mntent_file): Use a test file in / to check
616 to see if the root filesystem is mounted read-only. This
617 protects against the case where /etc might not be on /, as
618 well as the case where /etc/mtab doesn't exist. (Both are
619 should-never happen scenarios, but you never know...)
621 2001-06-14 Theodore Tso <tytso@valinux.com>
623 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
624 Remove unneeded #pragma argsused, since the arguments are
627 2001-06-13 Theodore Tso <tytso@valinux.com>
629 * ext2_types.h.in: If linux/types.h has been defined, then don't
630 try to redefine the typedefs.
632 * Makefile.in (HFILES): Add ext2_types.h to the list of files
633 which should be installed.
635 * ismounted.c (check_mntent_file): Work around GNU hurd brain
636 damage. Addresses Debian bug #100304.
638 * Makefile.in: Limit some .o files from being included into the
639 library if --disable-debugfs, --disable-swapfs,
640 --disable-imager, or --disable-resizer are used.
642 2001-06-12 Theodore Tso <tytso@valinux.com>
644 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
645 function, and use the ext2fs_badblocks_* functions
648 2001-06-11 Theodore Tso <tytso@valinux.com>
650 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
651 ext2fs_mark_generic_bitmap and
652 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
653 functions. (This saves space and doesn't significantly
654 change the speed of e2fsck on a P-III.)
656 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
657 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
658 include the byte-swapping logic if ENABLE_SWAPFS is turned
659 on or if we're on a big-endian machine.
661 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
662 set EXT2_FLAG_SWAP_BYTES, instead of using
665 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
666 autoconf to determine whether or not return
667 EXT2_FLAG_SWAP_BYTES.
669 2001-06-10 Theodore Tso <tytso@valinux.com>
671 * Makefile.in: Remove the dependence on the libe2p library.
673 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
674 with direct usage of the ioctl/fchflags so that we don't
675 have to depend on the libe2p library.
677 2001-06-08 Theodore Tso <tytso@valinux.com>
679 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
680 when trying to find a 32-bit wide type.
682 * icount.c (insert_icount_el): Fix the code used to estimate the
683 size of the new icount array to be more intelligent, to
684 avoid reallocating the array too many times. Thanks to
685 Enrique Perez-Terron for pointing this out.
687 2001-06-02 Theodore Tso <tytso@valinux.com>
689 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
690 for a symlink to determine whether it is a fast symlink.
692 2001-06-01 Theodore Tso <tytso@valinux.com>
694 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
695 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
697 2001-05-25 Theodore Tso <tytso@valinux.com>
699 * Release of E2fsprogs 1.20
701 2001-05-25 Theodore Tso <tytso@valinux.com>
703 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
704 some to clean up Andreas's patches. Use strncpy instead
705 of strcpy to save the root's mountpoint. Clean up #ifdef
706 structure. Remove uneeded variable in testing/debug driver.
708 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
710 * ismounted.c: Add check for root device which doesn't depend on
711 /etc/fstab or /proc/mounts to be correct. Don't call
712 endmntent() before we are done with mnt struct.
714 2001-05-23 Theodore Tso <tytso@valinux.com>
716 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
719 2001-05-21 Theodore Tso <tytso@valinux.com>
721 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
722 make room for pre-existing usage of
723 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
724 the same codepoint as EXT2_BTREE_FL.
726 2001-05-20 Theodore Tso <tytso@valinux.com>
728 * ext2fs.h: #include <> instead of "" for ext2fs and et header
729 files, since they will be installed in /usr/include
731 2001-05-14 Theodore Tso <tytso@valinux.com>
733 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
734 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
735 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
736 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,
737 expanddir.c, ext2_fs.h, fileio.c, finddev.c, flushb.c,
738 freefs.c, get_pathname.c, getsize.c, icount.c, imager.c,
739 initialize.c, inline.c, inode.c, irel_ma.c, ismounted.c,
740 link.c, lookup.c, mkdir.c, mkjournal.c, namei.c, native.c,
741 newdir.c, nt_io.c, openfs.c, read_bb.c, read_bb_file.c,
742 rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c,
743 tst_badblocks.c, tst_byteswap.c, tst_getsize.c,
744 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
745 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
746 Adjust all files in this directroy to include this file.
748 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
751 2001-05-05 Theodore Tso <tytso@valinux.com>
753 * fileio.c (ext2fs_file_read): Factored out common code and
754 cleaned up function. Fixed a bug where if there was an
755 error reading from the disk, the number of bytes read
756 wasn't reliably set. (Fixes Debian bug #79163)
757 (ext2fs_file_write): Factored out common code and made
758 function more efficient; if writing a full block, don't
759 bother to do a read-modify-write cycle.
761 2001-05-04 Theodore Tso <tytso@valinux.com>
763 * dirblock.c (ext2fs_read_dir_block): Check for an directory
764 record length which isn't a multiple four, and treat that
765 as an invalid. Scan the directory and return an error
766 (EXT2_ET_DIR_CORRUPTED) if the directory records are
768 (ext2fs_write_dir_block): If while byte-swapping the
769 directory block, if there's an error, abort and return
770 EXT2_ET_DIR_CORRUPTED.
772 2001-05-02 Theodore Tso <tytso@valinux.com>
774 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
775 image_header field in the ext2_filsys structure
777 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
778 * inode.c (ext2fs_read_inode):
779 * rw_bitmaps.c (read_bitmaps):
780 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
782 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
783 sure the full bitmap is saved.
785 2001-05-01 Theodore Tso <tytso@valinux.com>
787 * e2image.h (struct ext2_image_hdr): Add space for the device name
790 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
791 make sure the rec_len is a multiple of 4, to prevent
792 bus-errors on architectures which care about mis-aligned
795 2001-04-25 Theodore Tso <tytso@valinux.com>
797 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
798 query the device sizes using the BLKGETSIZE ioctl.
800 2001-04-16 Theodore Tso <tytso@valinux.com>
802 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
803 before checking /etc/mtab. The EXT2_MF_READONLY flag is
804 now set from the /etc/mtab options field for all
805 filesystems, not just the root filesystem. Add debugging
806 code to make it easier to test ext2fs_check_if_mounted().
808 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
809 check; return an error if there's an attempt to create a
810 journal less than 1024 filesystem blocks.
812 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
813 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
815 2001-02-20 Theodore Tso <tytso@valinux.com>
817 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
820 * tst_byteswap.c: New function to test the byteswap functions.
821 Add to regression test suite.
823 2001-02-08 Theodore Tso <tytso@valinux.com>
825 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
827 2001-02-07 Theodore Tso <tytso@valinux.com>
829 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
830 of s_first for external devices to always be 1, since
831 jsb->s_first is always relative to the start of the
832 journal superblock. Use htonl(1) when setting s_nr_users.
834 2001-01-17 Theodore Ts'o <tytso@valinux.com>
836 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
837 device number of the filesystem (instead of the journal)
838 was being dropped into s_journal_dev.
840 2001-01-15 Theodore Ts'o <tytso@valinux.com>
842 * initialize.c (ext2fs_initialize): Add support for initializing
843 the ext2 superblock for external journal devices. This
844 basically means we don't bother to allocate any block
847 * openfs.c (ext2fs_open): Only open external journal devices if
848 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
849 ext2fs_open. When opening such devices, don't try to read
850 the block group descriptors, since they're not there.
852 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
854 * mkjournal.c: Export a new function,
855 ext2fs_create_journal_superblock(), which allocates and
856 returns a buffer containing a journal superblock. This is
857 needed by mke2fs to create an external journal. Rewrote
858 ext2fs_add_journal_device() so that it no longer creates
859 the external journal, but rather adds a filesystem to an
860 existing external journal. It handles all of the UUID
863 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
864 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
865 Changed function prototype for ext2fs_add_journal_device().
867 2001-01-14 Theodore Ts'o <tytso@valinux.com>
869 * closefs.c (ext2fs_flush): Don't write out anything beyond the
870 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
873 2001-01-12 Theodore Ts'o <tytso@valinux.com>
875 * imager.c: Fix gcc -Wall complaints and a series of bugs where
876 retval wasn't set correctly. (Thanks to Andreas Dilger
877 for pointing this out.)
879 2001-01-11 <tytso@snap.thunk.org>
881 * flushb.c (ext2fs_sync_device): New function which centralizes
882 all of the places which might try to use the BLKFLSBUF
883 or FDFLUSH ioctls (and usually failing to define them
884 since the system header files don't usually do this for
885 us, and we're trying to avoid usage of kernel include
888 2001-01-10 <tytso@snap.thunk.org>
890 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
891 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
892 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
893 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
894 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
895 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
896 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
897 ext2_ino_t, to protect applications that attempt to
898 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
899 changes ino_t(!?). So we use ext2_ino_t to avoid an
900 unexpected ABI change.
902 2001-01-05 <tytso@snap.thunk.org>
904 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
905 we may overrun allocated memory in case of a corrupted
906 filesystem (or an e2fsck test case :-) when byte-swapping
909 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
911 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
912 complaints including a missing return 0 at the end of
913 ext2fs_add_journal_device.
915 2001-01-03 <tytso@snap.thunk.org>
917 * Makefile.in: Link in libe2p when creating libext2fs as a shared
918 library, since mkjournal.c now references fsetflags().
920 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
921 Dilger's changes (with fixups) to allow on-line creation
924 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
925 EXT2_FLAG_SUPER_ONLY, which the close routines to only
926 update the superblock, and not the group descriptors.
928 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
930 * ismounted.c: add ext2fs_check_mount_point() function, which will
931 optionally return the mount point of a device if mounted
933 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
935 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
936 ext2fs_add_journal_inode()
938 2001-01-01 <tytso@snap.thunk.org>
940 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
941 source (but not binary) compatibility of some users of the
942 ext2 library. They should just simply do a global search
943 and replace of struct ext2fs_sb with struct
944 ext2_super_block, and use their own private copy of
945 ext2_fs.h if they aren't already.
947 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
948 Replace use of ext2fs_sb with ext2_super_block.
950 2000-12-31 <tytso@snap.thunk.org>
952 * ext2fs.h: Cleaned up header file by removing definitions of
953 feature flags that might not have been defined in older
954 ext2 header files. Now that we're using our own
955 include/linux/ext2fs.h header file, this can never happen.
957 * jfs_dat.h: Removed old header file which is no longer needed.
959 2000-12-13 Theodore Ts'o <tytso@valinux.com>
961 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
962 by Andreas Dilger to update the filesystem revision to
965 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
968 2000-12-09 <tytso@snap.thunk.org>
970 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
971 ext2fs_add_journal_device): Add a new argument to the APIs
972 of these function, which is a flags word. This is used to
973 allow the creation of a V1 superblock for those folks who
974 are using ext3 0.3b in production. Note, the user-land
975 interface for getting at this flag won't be documented, as
976 the V1 superblock is deprecated.
978 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
979 which creates a V2 superblock instead of a V1 superblock.
981 2000-11-21 <tytso@snap.thunk.org>
983 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
984 out by Andreas Dilger.
986 2000-11-05 <tytso@snap.thunk.org>
988 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
989 ext2_fs.h, Makefile.in: New file that has routines that
990 save ext2fs metadata to a file.
992 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
994 * e2image.h: New file which defines the file format for the ext2
995 image file. (Saved copy of ext2 metadata to a file as a
996 saving throw against worst-case damage.)
998 2000-11-01 <tytso@snap.thunk.org>
1000 * inode.c (ext2fs_flush_icache): Add new function
1001 ext2fs_flush_icache() which flushes the internal inode
1002 cache. Applications which modify the inode table blocks
1003 directly must call this function.
1005 2000-10-26 <tytso@snap.thunk.org>
1007 * mkjournal.c: Add #include of netinet/in.h, since Solaris
1008 requires it for ntohl().
1010 * ext2_io.h (io_channel_write_byte): Add new interface to allow
1011 callers to write specific byte ranges. This is an
1012 optional interface, which not all IO channels may
1015 * unix_io.c (unix_write_byte):
1016 * test_io.c (test_write_byte): Add implementation of the
1017 write_byte function.
1019 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
1020 function which writes the primary superblock. If the IO
1021 channel supports writing raw bytes directly, only fields
1022 which were modified are written to the disk. This makes
1023 it safe(r) to use utilities like tune2fs on a mounted
1026 * freefs.c (ext2fs_free): Free the original superblock if it is
1029 * openfs.c (ext2fs_open): Store a copy of the original superblock
1032 * ext2fs.h: Add a field to store the original superblock in the
1033 ext2 context structure.
1035 2000-10-24 <tytso@snap.thunk.org>
1037 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
1038 don't need to use llseek).
1040 2000-10-24 <tytso@valinux.com>
1042 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
1043 creating an ext3 journal on a filesystem.
1045 2000-08-21 <tytso@valinux.com>
1047 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
1049 2000-08-22 <tytso@valinux.com>
1051 * unix_io.c: Make massive changes to support a multiple block
1052 writethrough cacheing.
1054 * ext2_io.h: Added flags field to the io_channel structure.
1056 2000-08-19 <tytso@valinux.com>
1058 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
1059 provides the function ext2fs_find_block_device(). This
1060 function returns the pathname to a block device, given its
1063 2000-07-13 <tytso@valinux.com>
1065 * Release of E2fsprogs 1.19
1067 2000-07-07 Theodore Ts'o <tytso@valinux.com>
1069 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
1070 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
1071 list of filesystem flags supported by the library.
1073 2000-07-04 Theodore Ts'o <tytso@valinux.com>
1075 * ext2fs.h: Update to include latest journalling additions to the
1078 * dll/jump.funcs: Add new jumptable entries for
1079 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1080 ext2fs_badblocks_equal.
1082 * tst_badblocks.c: Update test program to test
1083 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
1085 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
1086 writes out bad blocks list to a file.
1088 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
1089 changes the callback function to take two additional
1090 arguments; a private blind pointer supplied by the caller,
1091 and pointer to a char * containing a pointer to the
1094 * badblocks.c (ext2fs_badblocks_equal): Add new function which
1095 returns true if two badblocks list are equal.
1097 * Makefile.in: Remove explicit link of -lc in the shared library.
1098 (It shouldn't be necessary, and is harmful in some cases).
1100 2000-06-10 Theodore Ts'o <tytso@valinux.com>
1102 * getsize.c (main): Add debugging code under #ifdef DEBUG
1104 2000-05-27 Theodore Ts'o <tytso@valinux.com>
1106 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
1107 earlier, so that if there's an error reading it, we can
1108 more cleanly back out of the operation.
1110 2000-05-25 <tytso@snap.thunk.org>
1112 * getsize.c (ext2fs_get_device_size): Use open64() instead of
1113 open() if it exists. Under linux, manually define the
1114 ioctl for BLKGETSIZE if it isn't already defined and it's
1117 * unix_io.c (unix_open): Use open64() instead of open() if it
1120 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1121 available (and prototypes are defined) use it in
1122 preference to llseek.
1124 * Makefile: Add hack dependency rule so that parallel makes work
1127 2000-05-18 Theodore Ts'o <tytso@valinux.com>

1131 2000-04-03 Theodore Ts'o <tytso@valinux.com>
1133 * block.c: Readibility tweak in conditionals involving
1136 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
1137 how to define __s64 and __u64. Turn off "compression is
1138 experimental" warning if the cpp macro
1139 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
1141 2000-02-11 <tytso@snap.thunk.org>
1143 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
1144 Conditionally include Compression as a supported type if
1145 ENABLE_COMPRESSION (via --enable-compression) is turned on.
1147 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
1149 2000-02-08 <tytso@snap.thunk.org>
1151 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
1152 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1153 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
1154 Change to return the previous state of the bit that is
1155 being marked or unmarked. For speed optimization.
1157 2000-02-02 Theodore Ts'o <tytso@valinux.com>
1159 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
1161 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
1162 needed any more; we know it will always be i_generation.
1163 Add support for swapping the high bits of the uid and gid.
1165 1999-11-19 <tytso@valinux.com>
1167 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1168 counts if the link was successful. Patch suggested by
1171 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
1172 the source directory.
1174 1999-11-10 <tytso@valinux.com>
1176 * Release of E2fsprogs 1.18
1178 1999-11-08 <tytso@valinux.com>
1180 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1181 since ext2fs_badblocks_list_free was moved to freefs.c.
1183 * tst_badblocks.c: Use the newer badblocks API names. Add
1184 duplicate blocks to the test inputs to test dealing with
1185 adding blocks which are already in the badblocks list.
1187 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1188 of the list, use a shortcut O(1) operations instead of an
1189 O(n) operation. (Idea suggested by David Beattie.)
1191 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1192 of badblocks_list_free(), to save a procedure call.
1194 1999-10-26 <tytso@valinux.com>
1196 * Release of E2fsprogs 1.17
1198 1999-10-26 <tytso@valinux.com>
1200 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1201 seem to handle ~0UL the same way as they used to.
1203 1999-10-25 <tytso@valinux.com>
1205 * nt_io.c (_OpenNtName): Open the device using
1206 FILE_SYNCHRONOUS_IO_NONALERT instead of

1218 1999-10-22 <tytso@valinux.com>
1220 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1222 * link.c (ext2fs_link): This call now uses the low three bits of
1223 the flags parameter to pass the directory filetype
1224 information; it will set the directory entry FILETYPE
1225 information if the filesystem supports it.
1227 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1228 option is set, then create the '.' and '..' entries with
1229 the filetype set to EXT2_FT_DIR.
1231 1999-09-24 <tytso@valinux.com>
1233 * nt_io.c: New file which supports I/O under Windows NT.
1235 1999-09-07 <tytso@valinux.com>
1237 * ext2fs.h: Add new fields for journalling and define new
1238 feature bits used by newer filesystems: IMAGIC_INODES,
1239 HAS_JOURNAL, RECOVER.
1241 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1242 we update the inode block count and size files so that the
1243 block count field is updated correctly when we create an
1246 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1248 * Release of E2fsprogs 1.15
1250 1999-06-23 <tytso@valinux.com>
1252 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1253 kernels that use i_generation instead of i_version. Patch
1254 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1256 1999-06-21 <tytso@valinux.com>
1258 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1259 directory entry before calling the callback function.
1260 This should prevent some core dumps of insufficiently
1261 paranoid callback functions.
1263 1999-05-29 <tytso@rsts-11.mit.edu>
1265 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1267 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1268 that we don't handle writing yet (we do). Fixed bug where
1269 we weren't allocating a big enough buffer for ext2_bmap.
1271 1999-05-03 <tytso@rsts-11.mit.edu>
1273 * openfs.c (ext2fs_open): Check to make sure that the number of
1274 blocks per group is not zero --- if so, it must be a bad
1277 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1279 * Release of E2fsprogs 1.14
1281 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1283 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1284 the inode number is zero; if it's zero, return
1285 EXT2_ET_BAD_INODE_NUM.
1287 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1289 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1290 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1293 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1295 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1296 non-Linux case to use EINVAL by default, unless it isn't
1297 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1300 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1302 * Release of E2fsprogs 1.13
1304 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1306 * Makefile.in: Updated dependencies.
1308 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1310 * initialize.c (ext2fs_initialize): Make sure that we allocate
1311 enough inodes so that we can make a valid filesystem.
1313 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1315 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1317 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1318 function declaration.
1320 * dblist.c (make_dblist): Add safety check in case the dblist
1321 pointer passed in is null (in which case, assign it to
1322 fs->dblist). Fixed some signed/unsigned warnings.
1324 * bmap.c: Make addr_per_block be of type blk_t to avoid
1325 signed/unsigned warnings.
1327 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1328 function declaration.
1330 * get_pathname.c (get_pathname_proc): Use return value from
1331 ext2fs_get_mem, instead of checking if &gp->name is
1334 * dir_iterate.c (ext2fs_process_dir_block):
1335 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1336 from the function declaration.
1338 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1339 return the error directly instead of jumping to the
1340 cleanup routine, since we don't need to do any cleanup.
1342 * alloc_table.c (ext2fs_allocate_group_table): Make this
1343 function take a dgrp_t for its group argument.
1345 * ext2fs.h: Make dgrp_t an __u32 type, and make
1346 fs->desc_group_count be of type dgrp_t.
1348 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1350 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1351 than 10 blocks when we need to expand the size of the
1354 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1356 * Release of E2fsprogs 1.12
1358 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1360 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1361 appropriate for all of the block group copies, so that
1362 it's clear where the beginning of the filesystem is on the
1363 disk. (For when the partition table gets scrod.)
1365 * ext2fs.h: Change the name of the feature from
1366 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1367 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1369 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1371 * inode.c (get_next_blockgroup): Fix bug where if
1372 get_next_blockgroup() is called early because of a missing
1373 inode table in a block group, the current_inode counter
1374 wasn't incremented correctly.
1376 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1378 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1379 against a completely trashed bad block inode.
1381 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1383 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1384 the stride length hits a bad value, we retry the block
1385 allocation starting at the beginning of the block group.
1387 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1388 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1389 e2_blkcnt_t to avoid collision with LFS API.
1391 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1393 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1394 way that avoids overflows on disk sizes greater than 4GB.
1396 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1398 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1399 return type for comparison functions for qsort.
1401 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1404 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1406 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1409 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1410 evade a potential problem with glibc's header files trying
1411 to spike out linux/types.h.
1413 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1414 include the old size of the memory, which is needed for
1415 some braindamaged memory allocation systems that don't
1418 * badblocks.c (ext2fs_badblocks_list_add):
1419 bb_inode.c (clear_bad_block_proc):

1423 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1424 pass the old size of the memory to be resized to
1425 ext2fs_resize_mem().
1427 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1429 * Makefile.in: Change to use new installation directory variables
1430 convention. Fix uninstall rules to take $(DESTDIR) into
1433 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1435 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1436 with 32 bit longs, then we need to manually define __s64
1437 and __u64, since the current kernel header files don't
1438 define these if __STRICT_ANSI__ is defined. This is a
1439 problem if we are compiling with full GCC warnings, since
1440 we do need 64 bit support.
1442 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1443 since we're not using ext2fs_move_blocks() and there
1444 is some question as to its usefulness in its current
1447 * bmap.c (block_bmap): Remove unused function.
1449 * bmove.c (process_block): Fix -Wall warning.
1451 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1453 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1454 contain the offset into the inode.i_blocks array when
1455 ref_block is zero. Since we haven't done a formal
1456 release of e2fsprogs since block_iterate2 was first
1457 introduced, I removed block_iterate2, and renamed
1458 block_iterate3 to be block_iterate2.
1460 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1461 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1462 use of block_iterate and block_iterate2 to
1463 block_iterate2 with the new prototype for the
1464 interator function. (using blkcnt_t forr blockcount)
1466 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1468 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1469 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1470 conditional defines of new features COMPAT_DIR_PREALLOC,
1471 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1472 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1473 the library to declare that we support COMPAT_DIR_PREALLOC,
1474 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1476 * fileio.c: Rename function ext2fs_file_llseek to be
1477 ext2fs_file_lseek, which is more accurate.
1479 * block.c: Add new function ext2fs_block_iterate3 which calls
1480 the iterator function with the blockcount argument of
1481 type blkcnt_t. This version of the function is
1482 allowed to handle large files; the other fucntions are
1485 * ext2fs.h: Add new type blkcnt_t
1487 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1489 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1490 field wasn't getting correctly incremented for sparse
1491 files when the indirect or doubly-indirect block
1492 specified in the inode was zero.
1494 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1496 * unlink.c (unlink_proc):
1497 * lookup.c (lookup_proc):
1498 * link.c (link_proc):
1499 * get_pathname.c (get_pathname_proc):
1500 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1501 from dirent->name_len, so it can be used for other
1504 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1505 and indicate that we have support for this incompatible
1508 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1510 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
1512 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1514 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
1515 number of directories when the block group information is
1518 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1520 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1521 inode table is missing so that we catch the case where the
1522 first block group is missing.
1524 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1527 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1529 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1531 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1533 * test_io.c (test_flush): Add a debugging printf when the flush
1536 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1537 read in, return right away.
1539 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1541 * bitops.h: Don't try to do i386 inline asm functions if the
1544 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1545 instead of linux/types.h, and e2_bitops.h instead of
1548 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1551 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1553 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1554 so that we don't need to call get_next_blockgroup() the
1555 first time around. Saves a bit of time, and prevents us
1556 from needing to assign -1 to current_group (which is an
1559 * icount.c (insert_icount_el): Cast the estimated number of inodes
1560 from a float to an ino_t.
1562 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

1572 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1573 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is

1575 ext2-specific header files are in a flat directory.
1577 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1578 all assignments from void * to be compatible with C++.

1582 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
1583 make sure the contents of the disk are flushed to disk.
1585 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1599 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1601 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1602 paranoid about validating the directory counts from the
1603 block group information.
1605 * all files: Don't include stdlib.h anymore; include it in
1606 ext2_fs.h, since that file requires stdlib.h
1608 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1610 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1611 bitmap is loaded, and return an error if it is not.
1612 (expand_dir_proc): Only use ext2fs_write_dir_block when

1640 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1642 * [all files, basically]: Added definition of ext2fs_get_mem,
1643 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1644 changed all library routines to use these wrapper functions.

1647 instead of the system error messages.
1649 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
1652 * ext2fs.h: Added function declarations and constants for bmap.c
1655 * ext2_err.et.in: Added new error messages EXT2_FILE_RO and
1656 EXT2_ET_MAGIC_EXT2_FILE

1662 physical block number.
1664 * fileio.c: New file which implements simple file reading and
1667 * alloc.c (ext2fs_alloc_block): New function which allocates a
1668 block, zeros it, and updates the filesystem accounting
1669 records appropriately.
1671 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1673 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
1674 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
1675 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
1677 * Change various library files to use these functions instead of
1678 EINVAL, ENOENT, etc.
1680 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1682 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
1683 need to declare llseek().

1687 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1689 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
1691 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1727 * io.h: Change the prototype of ext2fs_llseek() to use int's
1728 instead of unsigned int's.
1730 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1731 to make life easer for GNU Libc 2.
1733 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1734 filesystem has its bitmaps stored as 32-bit words with bit
1735 0 as the LSB of each word. Thus a bitmap with only bit 0
1736 set would be, as a string of bytes, 00 00 00 01 00 ... To
1737 cope with this, we byte-reverse each word of a bitmap if
1738 we have a big-endian filesystem, that is, if we are *not*
1739 byte-swapping other word-sized numbers.

1772 * brel_ma.c: Fix to make be 16-bit safe.
1774 * link.c (ext2fs_link):

1798 * alloc.c alloc_tables.c badblocks.c bb_compat.c bb_inode.c
1799 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
1800 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c
1801 dirblock.c dupfs.c expanddir.c freefs.c get_pathname.c

1805 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
1806 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
1808 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1810 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1811 is zero, then return EXT2_IO_LLSEEK_FAILED.
1813 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1815 * Release of E2fsprogs 1.11
1817 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1819 * dblist.c (ext2fs_dblist_count): Added new function which returns
1820 the number of directory blocks in dblist.
1822 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1824 * unix_io.c (unix_flush): Make the io_channel flush function do a
1825 fsync to flush the kernel buffers to disk.
1827 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1829 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1830 current inode number wasn't being set by the
1831 goto_blockgroup function.
1833 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1835 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1836 of blocks which need to be moved, and moves those blocks
1837 to another location in the filesystem.
1839 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1840 bitmap, make sure all of the new parts of the bitmap are
1843 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1845 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1846 wasn't being returned to the caller.
1848 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1849 ext2fs_allocate_group_table() which sets the group tables
1850 for a particular block group. The relevant code was
1851 factored out of ext2fs_allocate_tables().
1853 * dblist.c (make_dblist): Adjust the initial size of the directory
1854 block list to be a bit more realistic (ten plus twice the
1855 number of directories in the filesystem).
1857 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1859 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1860 ext2fs_badblocks_list_test would test the list (and exceed
1861 array boundaries) if there were no bad blocks on the bad
1862 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1864 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1866 * Release of E2fsprogs version 1.10
1868 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1870 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1871 inode and block bitmaps based on the RAID 0 stride
1872 parameter (which is passed by mke2fs).
1874 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1875 mke2fs to communicate the stride length to
1876 ext2fs_allocate_tables()
1878 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1880 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1881 systems. (We can't assume that the new filesystem types
1884 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1886 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1887 allocate the inode and block bitmaps inside block group at
1890 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1892 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1893 filesystem has no free blocks, ext2fs_new_block would loop
1896 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1898 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1899 free if refcount goes to zero.

1911 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1913 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
1915 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1917 (unix_close, test_close): Decrement the refcount and only
1918 close the io_channel if the refcount goes to 0.
1920 * io.h: Add refcount to the io_channel structure. Add new macro
1921 interface io_channel_bumpcount() to bump the refcount.
1923 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1925 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1926 cache in the filesystem handle, instead of the inode cache
1927 in a static variable.
1929 * freefs.c: Added static function to free the inode cache (called by
1932 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1934 * ext2fs.h: Added pointer to the inode_cache structure.
1936 * block.c (block_iterate_ind, block_iterate_dind,
1937 block_iterate_tind): If there are holes in the indirect,

1939 block count field automatically.
1941 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1943 * Release of E2fsprogs version 1.09
1945 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1947 * version.c (ext2fs_parse_version_string): Check the passed in
1948 version string (instead of the hard-coded one).
1950 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1951 greater filesystem size, clamp it to prevent allocating a
1952 block or inode bitmap beyond the filesystem.
1954 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1955 overhead calculation was accidentally removed.
1957 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1959 * Release of E2fsprogs version 1.08
1961 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1964 block of a dblist entry, given the directory inode and
1967 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1969 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1970 inode bitmaps at staggered locations across the block
1971 groups, to avoid concentrating the bitmaps on a small
1972 number of disks when using striped RAID arrays.
1974 * initialize.c (ext2fs_initialize): By default, choose the maximum
1975 possible number of blocks per group (based on the size of
1976 the bitmaps in the blocksize).
1978 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1980 * initialize.c (ext2fs_initialize): Add support for
1981 EXT2_COMPAT_SPARSE_SUPER feature.
1983 * closefs.c (ext2fs_bg_has_super): New function to determine
1984 whether or a particular block group should have a
1985 superblock and block group descriptor. Used for the
1986 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1987 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1988 or not the superblock should be written out for the block
1991 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1992 for sparse duplicate superblocks.
1994 * version.c (ext2fs_get_library_version): New function which
1995 returns the library version.
1997 * version.c (ext2fs_parse_version_string): New function which
1998 parses a version string and returns a version number,
1999 so application programs can compare version numbers as
2002 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2004 * icount.c (ext2fs_create_icount): Change function so that it also
2005 takes a new argument which contains a "hint" icount
2006 structure. This "hint" icount allows the create function
2007 to set up the sorted list in advance. This reduces
2008 significantly the amount of data moving needed to insert
2009 these inodes into the list later.
2011 * icount.c (ext2fs_icount_validate): New function which validates
2012 that the icount structure's rep invariant.
2014 * icount.c (get_icount_el): Completely revamped implementation
2015 to subsume put_icount_el(). Put_icount_el() used to
2016 use an O(N) implementation to insert in the middle
2017 of the icount list. It now uses a O(ln N) to search
2018 for where the icount should be inserted, and then uses
2019 a memcpy to move the list down (instead of a for loop).
2021 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
2022 ext2fs_icount_increment, ext2fs_icount_decrement): Check
2023 to see if the inode is within bounds; if it isn't, return
2026 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
2027 when a bad inode number is passed to test_generic_bitmap
2028 to be EXT2FS_TEST_ERROR instead of the wrong
2029 EXT2FS_UNMARK_ERROR.
2031 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
2033 * Release of E2fsprogs version 1.07
2035 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2037 * Makefile.in (ELF_VERSION): Change version to be 2.2
2039 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2041 * alloc.c (ext2fs_get_free_blocks): Change routine to use
2042 ext2fs_fast_test_block_bitmap_range().

2045 ext2fs_test_block_bitmap_range: New inline functions which
2046 test to see whether a contiguous range of blocks is
2049 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2051 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
2052 use ext2fs_badblocks_* instead of badblocks_*
2054 * bb_compat.c: New file which translates between old badblocks_*()
2055 names to ext2fs_badblocks_*()
2057 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
2058 link.c (since e2fsck doesn't use ext2fs_unlink()).
2060 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
2061 bitmap resizing routine moved from bitmaps.c, since e2fsck
2062 doesn't need to use this function.
2064 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
2065 since e2fsck only needs ext2fs_lookup.
2067 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2069 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
2070 already set; this is needed so that programs like dump
2071 which use the inode scan functions will deal with
2072 filesystems that have bad blocks in the inode table.
2074 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2076 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
2077 Moved to ext2fsP.h, since it doesn't need to be part of
2078 the public interface.
2080 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
2082 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2084 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
2085 directory block list abstraction. (Code moved from
2088 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
2089 to inode.c (since no one else should be peeking inside it!)
2091 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
2093 * openfs.c (ext2fs_open): Check the feature set in the ext2
2094 superblock, and refuse to open filesystems if they contain
2095 incompatible features. (Can be overriden with the
2098 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2100 * block.c (ext2fs_block_iterate2): Added new function
2101 ext2fs_block_iterate2 which changes the function
2102 signature of the callback function to include the
2103 referencing block and offset.
2105 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
2106 ext2fs_inode_scan_goto_blockgroup which allows an
2107 application to jump to a particular block group while
2108 doing an inode scan.
2110 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2112 * dirblock.c: Include string.h, since we use memcpy().
2114 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2116 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2117 a long not an int; this doesn't matter on i386 machines,
2118 but it does on Alpha's.
2120 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2122 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2123 table pointer is NULL, then return an error indicating
2124 that the inode table is missing.
2125 (get_next_blockgroup, get_next_blocks,
2126 ext2fs_get_next_inode): Don't treat a missing inode table
2127 as permanent error. Return MISSING_INODE_TABLE, but as an
2128 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
2130 * rw_bitmaps.c (ext2fs_write_block_bitmap,
2131 ext2fs_write_inode_bitmap): If the inode or block bitmap
2132 block is zero, then don't write out the inode or block
2133 bitmap. The idea here is to avoid stomping on the
2135 (read_bitmaps): If the inode or block bitmap block is
2136 zero, then fill in that portion of the inode or block
2137 bitmap with all zeros.
2139 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
2140 blocks in inode table when the inode table size is
2141 non-standard (and can therefore span blocks).
2143 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2145 * alloc.c (ext2fs_new_block): Fix fencepost error in
2146 ext2fs_new_block; make sure we don't try to allocate the
2147 first block beyond the end of the filesystem.
2149 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2151 * inode.c (check_for_inode_bad_blocks): New function called by
2152 get_next_blocks() to avoid reading in bad blocks marked in
2153 fs->badblocks. Inodes located in bad blocks are returned
2154 by ext2fs_get_next_inode() returns the error code
2155 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
2157 * alloc_tables.c (ext2fs_allocate_tables): New function which
2158 performs the part of mke2fs's job of allocating the
2161 * test_io.c (test_close): IO manager which is used for testing
2164 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2166 * inode.c (ext2fs_get_next_inode): Separate out the function of
2167 setting up for a new block group to get_next_blockgroup().
2168 Separate out the function of reading in blocks of the
2169 inode table to get_next_blocks().
2171 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
2173 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2174 blocks to the badblock list in sorted order. This allows
2175 badblocks_list_test to be coded using a binary search for
2178 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2180 * Release of E2fsprogs version 1.06
2182 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2184 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2185 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2188 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2189 set, then only write out the master superblock.
2191 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2193 * block.c (ext2fs_block_iterate): Fixed bug which caused
2194 block_iterate to fail to handle HURD created filesystems;
2195 it tested the inode translator field before the inode was
2198 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2200 * initialize.c (ext2fs_initialize): Make sure the description for
2201 the inode bitmap is set correctly.

2207 * Release of E2fsprogs version 1.05
2209 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2211 * initialize.c: Override the kernel's idea of default
2212 checkinterval from 0 (never) to 180 days.
2214 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2216 * namei.c (ext2fs_namei_follow): New function which follows
2217 symbolic link (if any) at the target.
2219 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2221 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2222 for shortcut function fs->read_inode() and fs->write_inode().
2223 Added inode_cache to reduce CPU time spent in doing

2229 * namei.c (ext2fs_follow_link): New function.
2230 (ext2fs_namei): Extended to have support for chasing
2231 symbolic links. ext2fs_namei() still returns an inode
2232 which is a symbolic link. Symbolic links are only chased
2233 while resolving the containing directory. To chase
2234 symbolic links of the final result, use
2235 ext2fs_follow_link().
2237 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2239 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2241 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2242 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

2246 * initialize.c (ext2fs_initialize): On systems where the byte
2247 order is not i386 compatible, set the swap_byte flag.
2249 * inode.c (inocpy_with_swap): Check to see if inode contains a
2250 fast symlink before swapping the inode block fields. This
2251 required adding a new argument to inocpy_with_swap to
2252 determine whether the mode field is in host order or not.
2254 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2256 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2257 the sparc, if EXT2_STD_BITOPS set, use the standard
2258 i386-compatible bitmask operations, instead on the
2259 non-standard native bitmask operators.
2261 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2263 * block.c (ext2fs_block_iterate): Cause block iterator to return
2264 the HURD translator block (along with everything else).
2265 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2266 iterator, then don't return any meta data blocks
2267 (including the HURD translator).
2269 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2271 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2273 * uuid.c: New file, containing UUID utility functions.
2275 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2277 * ext2fs.h: Add a definition of the "real" ext2 superblock.
2279 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2281 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
2283 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2285 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2286 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2287 that's a basic value that must be correct for the rest of
2288 the library to work.
2290 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2293 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2303 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
2304 Change the m68k bit numbering for bitmasks to match with
2305 the bit numbering used by all other ext2 implementations.
2307 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
2309 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
2310 ext2fs_open_inode_scan): Support dynamically-sized inodes.
2312 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>

2325 * alloc.c (ext2fs_new_inode):
2326 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
2329 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>

2332 when trying to determine its size.
2334 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
2336 * Release of E2fsprogs version 1.02
2338 Sat Dec 9 09:57:50 1995 <tytso@rsts-11.mit.edu>

2341 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2342 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2343 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2344 to avoid conflicts with with kernel include files. Also
2345 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2348 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2350 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
2352 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
2353 s_def_resuid and s_def_resgid for backwards compatibility.
2355 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
2357 * bitops.h: Added #ifdef's for Sparc.
2359 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
2361 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
2364 * closefs.c: #include <string.h> to pick up memset() declaration
2366 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
2368 * Makefile.in: Added support for BSD shared libraries.
2370 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2373 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2375 * unix_io.c (unix_open): Add a double check; if the passed in name
2376 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2378 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2380 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

2387 * getsize.c (ext2fs_get_device_size): Add support for reading the
2388 partition size from a BSD disk label.
2390 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2392 * getsize.c (ext2fs_get_device_size): New function that determins
2393 the size of a device. Used by mke2fs and e2fsck.
2395 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
2397 * Makefile.in (install): Install static libraries in $(ulibdir)
2398 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).

2402 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2403 Move these functions to freefs.c.
2405 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2406 descriptors shadow memory to keep purify quiet. (This
2407 also has the nice benefit that the unused portion of the
2408 shadow descriptors are zeroed out.)
2410 * dirblock.c (ext2fs_write_dir_block): We need to use
2411 dirent->rec_len *before* it's byteswapped to find the
2412 location of the next directory structure!
2414 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2415 cause ext2fs_new_inode to loop infinitely if we're trying
2416 to allocate an inode in group #0 and there are no free
2417 inodes at all in the system.
2419 * closefs.c: #include <errno.h> if it exists.
2421 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2423 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2429 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
2430 installation directories correctly.
2432 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
2434 * namei.c (process_dir_block):
2435 * mkdir.c (ext2fs_mkdir):
2436 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
2437 to read/write the directory block.

2440 file containing functions for reading and writing
2441 directory blocks (byte swapping if necesssary)
2443 * block.c (block_iterate_ind, block_iterate_dind,
2444 block_iterate_tind): Byte swap the block addresses if
2445 EXT2_SWAP_BYTES is set (and swap them back before writing
2448 * inode.c (inocpy_with_swap): New function.
2449 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
2450 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2452 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2453 the superblock and group descriptors before writing it out.
2455 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2456 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2457 and group descriptors.
2459 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2460 to desp ext2 filesystem structures.
2462 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2463 supplied by Pete A. Zaitcev so that the C language
2464 versions of these functions are more portable. They will
2465 now work on both little and big endian systems, and the
2466 assumption that 32-bit integers are used is gone.
2468 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2469 doing byte swapping.
2471 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2472 byte swapping should take place.
2474 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

2485 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2486 if the magic number is correct, it will be allocated.
2488 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2490 * block.c (block_iterate_ind, block_iterate_dind,
2491 block_iterate_tind): Don't recompute block_nr each loop;
2492 just increment it! Factor check of BLOCK_FLAG_APPEND out
2493 of the loop. Factor mask of BLOCK_CHANGED into changed
2494 variable out of the loop. (block_iterate_ind, in
2495 particular, gets called a lot, so every little
2496 optimization helps.)
2498 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2500 * block.c (block_iterate_ind, block_iterate_dind,
2501 block_iterate_tind): Precompute limit of loop to speed up
2502 block_iterate_ind and company.

2506 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2507 ext2fs_fast_test_inode_bitmap): Add fast version of these
2508 functions, which don't do range checking.
2510 * bitops.h (ext2fs_get_block_bitmap_start,
2511 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2512 ext2fs_get_inode_bitmap_end): Add new accessor functions
2513 which return the start and end points of the bitmaps.
2515 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2517 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2518 instead of llseek. The errno if the offset is too large
2519 and lseek is not supported should be EINVAL, not -EINVAL.
2521 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2523 * Makefile.in: Added support for ELF shared libraries.
2524 Fixed typos in the compilation rules.
2525 (distclean): Added Makefile.
2527 * llseek.c (llseek): New function, if llseek() does not exist in the
2529 (ext2_llseek): Changed to call llseek().
2531 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2533 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.

2537 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2539 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2540 the S_*, which are normally defined in <sys/stat.h>. This
2541 allows us to compile e2fsprogs on a non-Linux system,
2542 which may have a different value for S_IFDIR.
2544 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2546 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2547 this is a user-mode application!
2549 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2551 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2552 __linux__ so that non-linux systems won't see it.
2554 * alloc.c: Include <errno.h> if possible.
2555 * badblocks.c: Ditto.
2556 * bb_inode.c: Ditto.
2559 * expanddir.c: Ditto.
2560 * get_pathname.c: Ditto.
2561 * initialize.c: Ditto.
2568 * rw_bitmaps.c: Ditto.
2571 * Makefile.in: Rewritten to conform to GNU coding standards and
2572 support separate compilation directories.
2574 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2576 * initialize.c (ext2fs_initialize): Don't allow more than one
2577 bitmaps's worth of inodes in a group.
2579 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2581 * llseek.c (ext2_llseek): Added error checking to the llseek()
2582 compat code to protect against overflow. This only
2583 applies to 1.0 and early 1.1 kernels, which don't support
2584 the llseek() system call.
2586 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2588 * unix_io.c (unix_open): Initialize the read_error and write_error
2589 io_channel pointers to be null.
2591 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2592 found, clear it but don't try to update the filesystem
2593 accounting information, since that's hopeless anyway.
2595 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2596 bloblock_iterate_tind): Check to see if the indirect blocks are
2597 valid before trying to read them.
2599 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
2600 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2602 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2603 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2604 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2605 illegal block or inode number is passed in, return instead
2606 of trying to test, set, or clear the bit.
2608 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2610 * Makefile: Added a dummy install target in case shared libraries
2613 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2615 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
2616 the real last block of the bitmap should be calculated.
2618 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
2620 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
2621 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
2622 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
2623 ext2fs_free_block_bitmap): Add magic number checking for
2624 the inode and block bitmaps.
2626 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2627 magic number for a block bitmap instead of an inode bitmap.
2629 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
2630 magic number checking for the inode_scan structure.
2632 * badblocks.c (badblocks_list_free, badblocks_list_add,
2633 badblocks_list_test, badblocks_list_iterate_begin,
2634 badblocks_list_iterate, badblocks_list_iterate_end): Add
2635 magic number checking for the badblocks_list and
2636 badblocks_iterate structures.
2638 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
2639 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
2640 unix_write_blk, unix_flush): Add magic number checking
2641 both for io_channel structure and unix_private_data
2644 * openfs.c (ext2fs_open): Add check for io_manager structure's
2647 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2648 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2649 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2650 * read_bb.c (ext2fs_read_bb_inode):
2651 * read_bb_file.c (ext2fs_read_bb_FILE):
2652 * newdir.c (ext2fs_new_dir_block):
2653 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
2654 * link.c (ext2fs_link, ext2fs_unlink):
2655 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
2656 ext2fs_write_inode, ext2fs_get_blocks,
2657 ext2fs_check_directory):
2658 * get_pathname.c (ext2fs_get_pathname):
2659 * expanddir.c (ext2fs_expand_dir):
2660 * block.c (ext2fs_block_iterate):
2661 * bitmaps.c (ext2fs_allocate_inode_bitmap,
2662 ext2fs_allocate_block_bitmap):
2663 * bb_inode.c (ext2fs_update_bb_inode):
2664 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
2665 * check_desc.c (ext2fs_check_desc):
2666 * closefs.c (ext2fs_close, ext2fs_flush):
2667 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2672 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2673 openfs.c into its own file.
2675 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2676 structure magic numbers.
2678 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2679 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2680 someone uses the -b option to specify the use of the backup
2681 superblock --- this usually means that the main superblock is
2685 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2686 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2687 revision level to the superblock.
2689 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2696 * initialize.c: Completely revamped the inode and block bitmap
2697 structures, so that they can be better chance of being extensible
2698 in a shared library. They are now their own type, instead of
2699 being a char *. Also, the function signatures of
2700 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2701 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2702 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2703 changed to eliminate the ext2_filsys argument, since it is no
2706 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2708 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2709 system call if available.
2711 * llseek.c: new file. This is the stub calling the llseek system
2712 call which allows supports for 2GB+ file systems.
2714 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2715 the creator operating system.
2717 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2719 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2720 the group descriptor statistics in addition to everything else.
2721 This relieves mke2fs of the responsibility of doing it.
2723 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2724 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2725 not the generic C function equivalents should be included or not.
2727 * openfs.c (ext2fs_open): If a superblock is specified, then use
2728 the backup group descriptors that go along with this superblock,
2729 instead of using the primary group descriptors. This allows
2730 e2fsck to recover filesystems where the primary group descriptors
