1 2002-10-31 Theodore Ts'o <tytso@mit.edu>
3 * Release of E2fsprogs 1.30
5 2002-10-31 Theodore Ts'o <tytso@mit.edu>
7 * ext2_fs.h: Add support for a new inode flag, which is to be used
8 for indicating the top of directory hierarchies for the
11 * ismounted.c (check_mntent, check_mntent_file): Add better
12 support for loopback-mounted filesystems. Check /etc/mtab
13 if /proc/mounts doesn't turn up any mount flags, since
14 /etc/mtab has the loopback image filename, instead of
15 /dev/loop0. Also, check based on st_dev and st_ino, so
16 that if a relative pathname or a pathnames using symbolic
17 links are used, we can detect the the filesystem correctly
18 in those cases. (Addresses Sourceforge bug #619119)
20 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
21 don't try the FDFLUSH ioctl that was required for floppies
22 with older kernels. This avoids needless whining from the
23 MD device driver. (Addresses Sourceforge bug #545832).
25 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
26 wrong group_block to ext2fs_descriptor_block_loc if we're
27 using the backup superblock/block group descriptors.
28 (ext2fs_descriptor_block_loc): If we're using the backup
29 superblock descriptors, use the backup descriptor block in
32 2002-10-30 Theodore Ts'o <tytso@mit.edu>
34 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
35 table so that it buts up against the bitmap blocks, to
36 avoid block fragmentation.
38 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
39 bug; only allocate group descriptor blocks up to
42 2002-10-25 Theodore Ts'o <tytso@mit.edu>
44 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
45 know when a filesystem was created. (Sometimes this can
48 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
50 2002-10-20 Theodore Ts'o <tytso@valinux.com>
52 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
53 the journal data mode.
55 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
56 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
57 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
58 the meta_blockgroup filesystem format.
60 2002-10-15 <tytso@snap.thunk.org>
62 * ext2_fs.h: Add new field in superblock for default mount options.
64 2002-10-13 Theodore Ts'o <tytso@mit.edu>
66 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
69 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
71 * rw_bitmaps.c (ext2fs_write_block_bitmap,
72 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
73 because the bitmap is getting written to disk. Make
74 ext2fs_swap_bitmap be a static function, since it's not
75 intended to be exported.
77 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
79 2001-09-24 Theodore Tso <tytso@mit.edu>
81 * Release of E2fsprogs 1.29
83 2001-08-31 Theodore Tso <tytso@thunk.org>
85 * Release of E2fsprogs 1.28
87 2002-08-31 Theodore Ts'o <tytso@valinux.com>
89 * dblist.c (ext2fs_dblist_sort): New function which allows the
90 caller to pass in a special sort comparison function.
92 2002-08-20 Theodore Ts'o <tytso@mit.edu>
94 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
95 failed to accurately characterize non-standard slow
96 symlinks. (Which don't appear in practice on real-life
97 systems, fortunately.)
99 2002-08-17 Theodore Ts'o <tytso@mit.edu>
101 * Makefile.in: Remove inode_io.o from the standard object files,
102 and only build it if debugfs is enabled (it requires
103 fileio.o, which is only built if --disable-debugfs isn't
104 specified to configure).
106 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
107 incompatible way so that it is no longer
108 endian-dependent. Add the TEA hash. Allow the seed
109 parameter to be optional.
111 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
112 These features are all now in the HALF_MD4 hash. Add
113 definition for EXT2_HASH_TEA.
115 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
116 a pointer instead of an array.
118 2002-08-16 Theodore Ts'o <tytso@mit.edu>
120 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
122 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
123 the number of data blocks used by an inode exclusive of
126 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
127 adjusts the reference count in an extended attribute block.
129 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
130 correctly deal with extended attribute blocks in symbolic
133 2002-08-13 <tytso@snap.thunk.org>
135 * Makefile.in: Move dupfs.o and test_io.o from the
136 needed-by-debugfs object list to the needed-by-resizer
137 object list. Fixes compile problem if the system is built
138 with only --disable-debugfs.
140 2002-07-29 Theodore Ts'o <tytso@mit.edu>
142 * link.c (ext2fs_link): When adding a new link to a directory,
145 2002-07-23 Theodore Ts'o <tytso@mit.edu>
147 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
148 calculations for names > 32 characters to be completely
149 bogus. Changed MD4 calculation to match what is currently
150 being used in the CVS gkernel tree.
152 2002-07-19 Theodore Ts'o <tytso@mit.edu>
154 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
155 superblock definition.
157 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
158 create a set of u32_list functions.
160 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
161 since that's required by the directory indexing code.
163 2002-07-14 Theodore Ts'o <tytso@mit.edu>
165 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
166 using a C++ reserved word.
168 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
169 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
170 old version of glibc (built against 2.2 headers) will
171 interact badly with the workaround to actually cause more
172 problems. I hate it when the glibc folks think they're
173 being smarter than the kernel....
175 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
177 * ext2_fs.h: Add superblock field for reserved group descriptors.
179 2002-06-28 Theodore Ts'o <tytso@mit.edu>
181 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
182 ext2fs_cpu_to_{l,b}e{32,16}
184 2002-06-27 Theodore Ts'o <tytso@mit.edu>
186 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
187 Add appropriate fallbacks in this case.
189 2002-06-26 Theodore Ts'o <tytso@mit.edu>
191 * dirhash.c (ext2fs_dirhash): Change function signature to support
192 a hash seed, and to return the minor hash (for 64-bit hash
193 support). Add support for the half MD4, half MD4 with
194 seed, and half MD4 with seed and 64 bits.
196 2002-06-15 Theodore Ts'o <tytso@mit.edu>
198 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
200 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
202 * ext2_fs.h: Add macros for maximum block/inode counts:
203 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
204 and EXT2_MAX_INODES_PER_GROUP.
206 * openfs.c (ext2fs_open): Check that the number of blocks in a group
207 is less than 2^16, otherwise we need an INCOMPAT flag (not
208 in existence yet, if ever) to open such a filesystem.
210 * initialize.c (ext2fs_initialize): Limit the number of blocks and
211 inodes in a group to less than 2^16.
213 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
215 * ext2_fs.h: Further minor cleanups of the header. Consolidate
216 some checks for __KERNEL__ into one place.
218 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
220 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
221 the EXT2_SB() macro instead. Remove kernel function
222 prototypes also. This matches the 2.5 kernel, and
223 is also cleaner for other reasons. Whitespace cleanup.
225 2002-05-21 Theodore Ts'o <tytso@mit.edu>
227 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
229 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
231 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
233 * initialize.c (ext2fs_initialize): Remove assumption that
234 blocksizes are always <= 4k.
236 2002-05-11 Theodore Ts'o <tytso@mit.edu>
238 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
239 silently if inode pointer is NULL (and ext2fs_bmap is
240 expected to read the inode itself).
242 2002-04-27 Theodore Ts'o <tytso@mit.edu>
244 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
245 file we are checking is a block device file before looking
246 at st_rdev, since it's not valid for normal files.
247 (is_swap_device): Move so that it is outside the
248 HAVE_MNTENT_H, so that it is always built.
250 2002-03-11 Theodore Tso <tytso@mit.edu>
252 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
253 functions which take an extra flags argument. The flag
254 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
255 field is byte swampped on big-endian machines, since in
256 the V2 structure, name_len is a char field which is
257 doesn't need to be byte swapped --- except if an
258 old-style kernel had byte-swapped the name_len field
259 as part of the V1 structure.
261 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
263 * dirhash.c (ext2fs_dirhash): New function which calculates the
264 hash for a filename in an indexed directory.
266 2002-03-08 Theodore Tso <tytso@mit.edu>
268 * Release of E2fsprogs 1.27
270 2002-03-07 Theodore Tso <tytso@mit.edu>
272 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
274 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
275 tst_byteswap.c: Fix gcc -Wall complaints
277 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
278 (From Philipp Thomas <pthomas@suse.de>)
280 2002-02-25 Theodore Tso <tytso@mit.edu>
282 * ext2_fs.h: Add structure definitions for the directory indexing
285 2002-02-23 Theodore Tso <tytso@mit.edu>
287 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
288 it doesn't break things on mis32, sparc32, and alpha
291 2002-02-21 Theodore Tso <tytso@mit.edu>
293 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
294 we were missing an fclose().
296 2002-02-20 Theodore Tso <tytso@mit.edu>
298 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
299 abstraction interface which exports an ext2 inode.
301 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
302 as a public interface. Change void * to const void * in
303 ext2fs_file_write's interface.
305 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
306 conditional; save a few bytes.
308 2002-02-12 Theodore Tso <tytso@mit.edu>
310 * Makefile.in (tst_badblocks): Add some extra .o files when
311 linking the debugging program tst_badblocks which are
312 needed if we aren't compiling with inline functions enable.
314 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
315 define away __inline__ since it may not be supported.
317 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
318 stripped down jbd_debug that doesn't use variadic
319 arguments. This will cause warnings under AIX, but things
322 2002-02-03 Theodore Tso <tytso@thunk.org>
324 * Release of E2fsprogs 1.26
326 2002-02-03 Theodore Tso <tytso@mit.edu>
328 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
329 so that the number of directories in use is adjusted
332 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
333 which optionally will modify the number of directories
336 2002-01-03 Theodore Tso <tytso@mit.edu>
338 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
339 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
340 which will return deleted directory entries.
341 ext2fs_dir_iterate2 takes a new callback function which
342 is identical with the one used by
343 ext2fs_dblist_dir_iterate(). If the directory entry is
344 deleted, the callback function will be called with the
345 entry paraemter set to DIRENT_DELETED_FILE.
347 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
348 ext2fs_block_alloc_stats): New functions which update
349 block/inode allocation statistics in the bitmaps, block
350 group descriptors, and superblock.
352 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
353 expanddir.c (expand_dir_proc), bb_inode.c
354 (clear_bad_block_proc, set_bad_block_proc,
355 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
356 Update to use new block/inode allocation statistics.
358 2001-12-24 Theodore Tso <tytso@mit.edu>
360 * ismounted.c (is_swap_device): New function used by
361 ext2fs_check_if_mounted and ext2fs_check_mount_point which
362 determines whether or not the specified device is a swap
363 device by using /proc/swaps. More bulletproofing for
364 idiotic/careless system administrators!
366 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
367 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
368 field to struct_ext2_filsys, umask. This field is
369 initialize to 022, and affects ext2fs_mkdir in the obvious
370 way. (In the future umask should also affect new file
371 creation routines, but the fileio functions don't
372 currently support this yes.)
374 * ismounted.c (check_mntent_file): Stat all of the entries in
375 /etc/mtab and/or /proc/mounts in order to catch dim-witted
376 system administrators who might have created alias
379 2001-12-23 Theodore Tso <tytso@mit.edu>
381 * Makefile.in, jfs_user.h: Move linux/jbd.h to
382 ext2fs/kernel-jbd.h, to avoid using the system header
383 file version of hbd.h when using diet glibc (since it
384 forcibly adds /usr/include to the beginning of the
385 include search path.)
387 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
388 include/linux directory.
390 2001-12-16 Theodore Tso <tytso@mit.edu>
392 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
393 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
394 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
396 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
399 2001-12-03 Theodore Tso <tytso@mit.edu>
401 * unix_io.c (unix_open): Make sure the ulimit workaround works
402 regardless of the version of glibc which is used to
405 2001-11-26 Theodore Tso <tytso@mit.edu>
407 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
408 trying to unset the filesize limit if at all possible,
409 if a block device is getting opened. (The filesize limit
410 shouldn't be applied against writes to a block device, but
411 starting in 2.4.10, the kernel is doing this.)
413 2001-11-05 Theodore Tso <tytso@mit.edu>
415 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
416 file on adding a journal to an already-mounted filesystem,
417 try to clear the ext2 file attributes on an already
418 existing .journal file so that we don't fail if on a
419 partially added journal to the filesystem.
421 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
422 which signals that a particular inode should not have the
423 last bits of data (the "tail") be merged with another
424 file. This is necessary to keep LILO happy.
426 2001-09-20 Theodore Tso <tytso@thunk.org>
428 * Release of E2fsprogs 1.25
430 2001-09-16 Theodore Tso <tytso@mit.edu>
432 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
433 which was breaking the build on the Hurd. (Addresses
436 2001-09-13 Theodore Ts'o <tytso@mit.edu>
438 * ismounted.c (check_mntent_file): We now validate the entry in
439 /etc/mtab to make sure the filesystem is really mounted,
440 since some broken distributions (read: Slackware) have
441 buggy boot scripts that don't initialize /etc/mtab before
442 checking non-root filesystems. (Slackware also doesn't
443 check the root filesystem separately, and reboot if the
444 root filesystem had changes applied to it, which is
445 dangerous and broken.)
447 2001-09-02 Theodore Tso <tytso@thunk.org>
449 * Release of E2fsprogs 1.24a
451 2001-08-30 Theodore Tso <tytso@thunk.org>
453 * Release of E2fsprogs 1.24
455 2001-08-30 Theodore Tso <tytso@valinux.com>
457 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
458 changes, since the ioctl number has been reused by another
461 2001-08-15 Theodore Tso <tytso@valinux.com>
463 * Release of E2fsprogs 1.23
465 2001-08-05 Theodore Tso <tytso@valinux.com>
467 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
468 version of the bitmap test routines to speed up these
469 routines. (At some point I may want to make these
470 routines use the find_first_bit functions, but that will
471 add a lot of complexity since it means that these
472 functions will have to break the bitmap abstraction
473 boundary. It's not clear it's worth it.)
475 * mkjournal.c (mkjournal_proc): Remember the last block allocated
476 to speed up ext2fs_new_block().
478 2001-07-29 Theodore Tso <tytso@valinux.com>
480 * finddev.c (scan_dir): Fix memory leak; we weren't calling
481 closedir() when exiting the function in all cases.
483 2001-07-27 Theodore Tso <tytso@valinux.com>
485 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
486 block usable in the journal for external journals to be 2
487 or 3, depending on the blocksize, so that the existing
488 kernel code does the right thing.
490 * getsize.c (ext2fs_get_device_size): Add support for the
491 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
492 from Ben LaHaise, but it's likely this interface won't
495 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
496 when writing the journal superblock, too. (Oops! Needed
497 to make 1k filesystems with external journal to work.)
499 2001-07-26 Theodore Tso <tytso@valinux.com>
501 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
502 to find the journal superblock if the blocksize is 1024.
504 2001-07-21 Theodore Tso <tytso@valinux.com>
506 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
508 2001-07-20 Theodore Tso <tytso@valinux.com>
510 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
511 attribute block, set the filesystem changed bit.
513 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
514 Comment out these functions since we're not using them.
516 2001-07-10 Theodore Tso <tytso@valinux.com>
518 * closefs.c (write_primary_superblock): After writing changes to
519 the primary superblock, update the original superblock
520 copy so we don't have to re-write those changes in the
522 (ext2fs_flush): Clear the superblock dirty flag after
523 we've flushed out changes to disk.
525 2001-07-07 Theodore Tso <tytso@valinux.com>
527 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
528 to avoid register conflicts when compiling in PIC mode.
530 2001-07-04 Theodore Tso <tytso@valinux.com>
532 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
533 Add new functions (C and in i386 assembler) which quickly
534 find bits set in a bitmask.
536 2001-06-23 Theodore Tso <tytso@valinux.com>
538 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
539 ext2_ext_attr.h and ext_attr.c for extended attributes
542 * Release of E2fsprogs 1.22
544 2001-06-22 Theodore Tso <tytso@valinux.com>
546 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
547 descriptor so that adding a journal to a mounted
548 filesystem doesn't die. (Fixes a bug accidentally
549 introduced in e2fsprogs 1.21.)
551 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
552 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
553 fchflags without defining UF_NODUMP. (Addresses Debian
556 * flushb.c: Use platform independent method of defining the
557 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
558 since on newer glibc's BLKFLSBUF is defined there.
560 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
561 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
562 to support byte swapping even if we don't support the
563 conversion functions. (Fixes Debian bug #101686).
565 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
566 since the byte-swapping code all assumes the
567 ext2_dir_entry structure. (It's a question of whether or
568 not name_len should be byte-swapped or not, and whether
569 it's a 16 bit or 8 bit field.)
571 2001-06-15 Theodore Tso <tytso@valinux.com>
573 * Release of E2fsprogs 1.21
575 2001-06-15 Theodore Tso <tytso@valinux.com>
577 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
578 file which is generated and is therefore found in the
579 build directory, not source directory.
581 * ismounted.c (check_mntent_file): Use a test file in / to check
582 to see if the root filesystem is mounted read-only. This
583 protects against the case where /etc might not be on /, as
584 well as the case where /etc/mtab doesn't exist. (Both are
585 should-never happen scenarios, but you never know...)
587 2001-06-14 Theodore Tso <tytso@valinux.com>
589 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
590 Remove unneeded #pragma argsused, since the arguments are
593 2001-06-13 Theodore Tso <tytso@valinux.com>
595 * ext2_types.h.in: If linux/types.h has been defined, then don't
596 try to redefine the typedefs.
598 * Makefile.in (HFILES): Add ext2_types.h to the list of files
599 which should be installed.
601 * ismounted.c (check_mntent_file): Work around GNU hurd brain
602 damage. Addresses Debian bug #100304.
604 * Makefile.in: Limit some .o files from being included into the
605 library if --disable-debugfs, --disable-swapfs,
606 --disable-imager, or --disable-resizer are used.
608 2001-06-12 Theodore Tso <tytso@valinux.com>
610 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
611 function, and use the ext2fs_badblocks_* functions
614 2001-06-11 Theodore Tso <tytso@valinux.com>
616 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
617 ext2fs_mark_generic_bitmap and
618 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
619 functions. (This saves space and doesn't significantly
620 change the speed of e2fsck on a P-III.)
622 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
623 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
624 include the byte-swapping logic if ENABLE_SWAPFS is turned
625 on or if we're on a big-endian machine.
627 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
628 set EXT2_FLAG_SWAP_BYTES, instead of using
631 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
632 autoconf to determine whether or not return
633 EXT2_FLAG_SWAP_BYTES.
635 2001-06-10 Theodore Tso <tytso@valinux.com>
637 * Makefile.in: Remove the dependence on the libe2p library.
639 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
640 with direct usage of the ioctl/fchflags so that we don't
641 have to depend on the libe2p library.
643 2001-06-08 Theodore Tso <tytso@valinux.com>
645 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
646 when trying to find a 32-bit wide type.
648 * icount.c (insert_icount_el): Fix the code used to estimate the
649 size of the new icount array to be more intelligent, to
650 avoid reallocating the array too many times. Thanks to
651 Enrique Perez-Terron for pointing this out.
653 2001-06-02 Theodore Tso <tytso@valinux.com>
655 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
656 for a symlink to determine whether it is a fast symlink.
658 2001-06-01 Theodore Tso <tytso@valinux.com>
660 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
661 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
663 2001-05-25 Theodore Tso <tytso@valinux.com>
665 * Release of E2fsprogs 1.20
667 2001-05-25 Theodore Tso <tytso@valinux.com>
669 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
670 some to clean up Andreas's patches. Use strncpy instead
671 of strcpy to save the root's mountpoint. Clean up #ifdef
672 structure. Remove uneeded variable in testing/debug driver.
674 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
676 * ismounted.c: Add check for root device which doesn't depend on
677 /etc/fstab or /proc/mounts to be correct. Don't call
678 endmntent() before we are done with mnt struct.
680 2001-05-23 Theodore Tso <tytso@valinux.com>
682 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
685 2001-05-21 Theodore Tso <tytso@valinux.com>
687 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
688 make room for pre-existing usage of
689 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
690 the same codepoint as EXT2_BTREE_FL.
692 2001-05-20 Theodore Tso <tytso@valinux.com>
694 * ext2fs.h: #include <> instead of "" for ext2fs and et header
695 files, since they will be installed in /usr/include
697 2001-05-14 Theodore Tso <tytso@valinux.com>
699 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
700 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
701 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
702 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,

708 rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c,
709 tst_badblocks.c, tst_byteswap.c, tst_getsize.c,
710 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
711 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
712 Adjust all files in this directroy to include this file.
714 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
717 2001-05-05 Theodore Tso <tytso@valinux.com>
719 * fileio.c (ext2fs_file_read): Factored out common code and
720 cleaned up function. Fixed a bug where if there was an
721 error reading from the disk, the number of bytes read
722 wasn't reliably set. (Fixes Debian bug #79163)
723 (ext2fs_file_write): Factored out common code and made
724 function more efficient; if writing a full block, don't
725 bother to do a read-modify-write cycle.
727 2001-05-04 Theodore Tso <tytso@valinux.com>
729 * dirblock.c (ext2fs_read_dir_block): Check for an directory
730 record length which isn't a multiple four, and treat that
731 as an invalid. Scan the directory and return an error
732 (EXT2_ET_DIR_CORRUPTED) if the directory records are
734 (ext2fs_write_dir_block): If while byte-swapping the
735 directory block, if there's an error, abort and return
736 EXT2_ET_DIR_CORRUPTED.
738 2001-05-02 Theodore Tso <tytso@valinux.com>
740 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
741 image_header field in the ext2_filsys structure
743 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
744 * inode.c (ext2fs_read_inode):
745 * rw_bitmaps.c (read_bitmaps):
746 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
748 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
749 sure the full bitmap is saved.
751 2001-05-01 Theodore Tso <tytso@valinux.com>
753 * e2image.h (struct ext2_image_hdr): Add space for the device name
756 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
757 make sure the rec_len is a multiple of 4, to prevent
758 bus-errors on architectures which care about mis-aligned
761 2001-04-25 Theodore Tso <tytso@valinux.com>
763 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
764 query the device sizes using the BLKGETSIZE ioctl.
766 2001-04-16 Theodore Tso <tytso@valinux.com>
768 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
769 before checking /etc/mtab. The EXT2_MF_READONLY flag is
770 now set from the /etc/mtab options field for all
771 filesystems, not just the root filesystem. Add debugging
772 code to make it easier to test ext2fs_check_if_mounted().
774 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
775 check; return an error if there's an attempt to create a
776 journal less than 1024 filesystem blocks.
778 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
779 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
781 2001-02-20 Theodore Tso <tytso@valinux.com>
783 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
786 * tst_byteswap.c: New function to test the byteswap functions.
787 Add to regression test suite.
789 2001-02-08 Theodore Tso <tytso@valinux.com>
791 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
793 2001-02-07 Theodore Tso <tytso@valinux.com>
795 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
796 of s_first for external devices to always be 1, since
797 jsb->s_first is always relative to the start of the
798 journal superblock. Use htonl(1) when setting s_nr_users.
800 2001-01-17 Theodore Ts'o <tytso@valinux.com>
802 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
803 device number of the filesystem (instead of the journal)
804 was being dropped into s_journal_dev.
806 2001-01-15 Theodore Ts'o <tytso@valinux.com>
808 * initialize.c (ext2fs_initialize): Add support for initializing
809 the ext2 superblock for external journal devices. This
810 basically means we don't bother to allocate any block
813 * openfs.c (ext2fs_open): Only open external journal devices if
814 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
815 ext2fs_open. When opening such devices, don't try to read
816 the block group descriptors, since they're not there.
818 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
820 * mkjournal.c: Export a new function,
821 ext2fs_create_journal_superblock(), which allocates and
822 returns a buffer containing a journal superblock. This is
823 needed by mke2fs to create an external journal. Rewrote
824 ext2fs_add_journal_device() so that it no longer creates
825 the external journal, but rather adds a filesystem to an
826 existing external journal. It handles all of the UUID
829 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
830 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
831 Changed function prototype for ext2fs_add_journal_device().
833 2001-01-14 Theodore Ts'o <tytso@valinux.com>
835 * closefs.c (ext2fs_flush): Don't write out anything beyond the
836 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
839 2001-01-12 Theodore Ts'o <tytso@valinux.com>
841 * imager.c: Fix gcc -Wall complaints and a series of bugs where
842 retval wasn't set correctly. (Thanks to Andreas Dilger
843 for pointing this out.)
845 2001-01-11 <tytso@snap.thunk.org>
847 * flushb.c (ext2fs_sync_device): New function which centralizes
848 all of the places which might try to use the BLKFLSBUF
849 or FDFLUSH ioctls (and usually failing to define them
850 since the system header files don't usually do this for
851 us, and we're trying to avoid usage of kernel include
854 2001-01-10 <tytso@snap.thunk.org>
856 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
857 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
858 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
859 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
860 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
861 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
862 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
863 ext2_ino_t, to protect applications that attempt to
864 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
865 changes ino_t(!?). So we use ext2_ino_t to avoid an
866 unexpected ABI change.
868 2001-01-05 <tytso@snap.thunk.org>
870 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
871 we may overrun allocated memory in case of a corrupted
872 filesystem (or an e2fsck test case :-) when byte-swapping
875 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
877 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
878 complaints including a missing return 0 at the end of
879 ext2fs_add_journal_device.
881 2001-01-03 <tytso@snap.thunk.org>
883 * Makefile.in: Link in libe2p when creating libext2fs as a shared
884 library, since mkjournal.c now references fsetflags().
886 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
887 Dilger's changes (with fixups) to allow on-line creation
890 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
891 EXT2_FLAG_SUPER_ONLY, which the close routines to only
892 update the superblock, and not the group descriptors.
894 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
896 * ismounted.c: add ext2fs_check_mount_point() function, which will
897 optionally return the mount point of a device if mounted
899 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
901 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
902 ext2fs_add_journal_inode()
904 2001-01-01 <tytso@snap.thunk.org>
906 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
907 source (but not binary) compatibility of some users of the
908 ext2 library. They should just simply do a global search
909 and replace of struct ext2fs_sb with struct
910 ext2_super_block, and use their own private copy of
911 ext2_fs.h if they aren't already.
913 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
914 Replace use of ext2fs_sb with ext2_super_block.
916 2000-12-31 <tytso@snap.thunk.org>
918 * ext2fs.h: Cleaned up header file by removing definitions of
919 feature flags that might not have been defined in older
920 ext2 header files. Now that we're using our own
921 include/linux/ext2fs.h header file, this can never happen.
923 * jfs_dat.h: Removed old header file which is no longer needed.
925 2000-12-13 Theodore Ts'o <tytso@valinux.com>
927 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
928 by Andreas Dilger to update the filesystem revision to
931 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
934 2000-12-09 <tytso@snap.thunk.org>
936 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
937 ext2fs_add_journal_device): Add a new argument to the APIs
938 of these function, which is a flags word. This is used to
939 allow the creation of a V1 superblock for those folks who
940 are using ext3 0.3b in production. Note, the user-land
941 interface for getting at this flag won't be documented, as
942 the V1 superblock is deprecated.
944 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
945 which creates a V2 superblock instead of a V1 superblock.
947 2000-11-21 <tytso@snap.thunk.org>
949 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
950 out by Andreas Dilger.
952 2000-11-05 <tytso@snap.thunk.org>
954 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
955 ext2_fs.h, Makefile.in: New file that has routines that
956 save ext2fs metadata to a file.
958 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
960 * e2image.h: New file which defines the file format for the ext2
961 image file. (Saved copy of ext2 metadata to a file as a
962 saving throw against worst-case damage.)
964 2000-11-01 <tytso@snap.thunk.org>
966 * inode.c (ext2fs_flush_icache): Add new function
967 ext2fs_flush_icache() which flushes the internal inode
968 cache. Applications which modify the inode table blocks
969 directly must call this function.
971 2000-10-26 <tytso@snap.thunk.org>
973 * mkjournal.c: Add #include of netinet/in.h, since Solaris
974 requires it for ntohl().
976 * ext2_io.h (io_channel_write_byte): Add new interface to allow
977 callers to write specific byte ranges. This is an
978 optional interface, which not all IO channels may
981 * unix_io.c (unix_write_byte):
982 * test_io.c (test_write_byte): Add implementation of the
985 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
986 function which writes the primary superblock. If the IO
987 channel supports writing raw bytes directly, only fields
988 which were modified are written to the disk. This makes
989 it safe(r) to use utilities like tune2fs on a mounted
992 * freefs.c (ext2fs_free): Free the original superblock if it is
995 * openfs.c (ext2fs_open): Store a copy of the original superblock
998 * ext2fs.h: Add a field to store the original superblock in the
999 ext2 context structure.
1001 2000-10-24 <tytso@snap.thunk.org>
1003 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
1004 don't need to use llseek).
1006 2000-10-24 <tytso@valinux.com>
1008 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
1009 creating an ext3 journal on a filesystem.
1011 2000-08-21 <tytso@valinux.com>
1013 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
1015 2000-08-22 <tytso@valinux.com>
1017 * unix_io.c: Make massive changes to support a multiple block
1018 writethrough cacheing.
1020 * ext2_io.h: Added flags field to the io_channel structure.
1022 2000-08-19 <tytso@valinux.com>
1024 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
1025 provides the function ext2fs_find_block_device(). This
1026 function returns the pathname to a block device, given its
1029 2000-07-13 <tytso@valinux.com>
1031 * Release of E2fsprogs 1.19
1033 2000-07-07 Theodore Ts'o <tytso@valinux.com>
1035 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
1036 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
1037 list of filesystem flags supported by the library.
1039 2000-07-04 Theodore Ts'o <tytso@valinux.com>
1041 * ext2fs.h: Update to include latest journalling additions to the
1044 * dll/jump.funcs: Add new jumptable entries for
1045 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1046 ext2fs_badblocks_equal.
1048 * tst_badblocks.c: Update test program to test
1049 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
1051 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
1052 writes out bad blocks list to a file.
1054 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
1055 changes the callback function to take two additional
1056 arguments; a private blind pointer supplied by the caller,
1057 and pointer to a char * containing a pointer to the
1060 * badblocks.c (ext2fs_badblocks_equal): Add new function which
1061 returns true if two badblocks list are equal.
1063 * Makefile.in: Remove explicit link of -lc in the shared library.
1064 (It shouldn't be necessary, and is harmful in some cases).
1066 2000-06-10 Theodore Ts'o <tytso@valinux.com>
1068 * getsize.c (main): Add debugging code under #ifdef DEBUG
1070 2000-05-27 Theodore Ts'o <tytso@valinux.com>
1072 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
1073 earlier, so that if there's an error reading it, we can
1074 more cleanly back out of the operation.
1076 2000-05-25 <tytso@snap.thunk.org>
1078 * getsize.c (ext2fs_get_device_size): Use open64() instead of
1079 open() if it exists. Under linux, manually define the
1080 ioctl for BLKGETSIZE if it isn't already defined and it's
1083 * unix_io.c (unix_open): Use open64() instead of open() if it
1086 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1087 available (and prototypes are defined) use it in
1088 preference to llseek.
1090 * Makefile: Add hack dependency rule so that parallel makes work
1093 2000-05-18 Theodore Ts'o <tytso@valinux.com>

1097 2000-04-03 Theodore Ts'o <tytso@valinux.com>
1099 * block.c: Readibility tweak in conditionals involving
1102 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
1103 how to define __s64 and __u64. Turn off "compression is
1104 experimental" warning if the cpp macro
1105 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
1107 2000-02-11 <tytso@snap.thunk.org>
1109 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
1110 Conditionally include Compression as a supported type if
1111 ENABLE_COMPRESSION (via --enable-compression) is turned on.
1113 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
1115 2000-02-08 <tytso@snap.thunk.org>
1117 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
1118 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1119 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
1120 Change to return the previous state of the bit that is
1121 being marked or unmarked. For speed optimization.
1123 2000-02-02 Theodore Ts'o <tytso@valinux.com>
1125 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
1127 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
1128 needed any more; we know it will always be i_generation.
1129 Add support for swapping the high bits of the uid and gid.
1131 1999-11-19 <tytso@valinux.com>
1133 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1134 counts if the link was successful. Patch suggested by

1138 the source directory.
1140 1999-11-10 <tytso@valinux.com>
1142 * Release of E2fsprogs 1.18
1144 1999-11-08 <tytso@valinux.com>
1146 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1147 since ext2fs_badblocks_list_free was moved to freefs.c.
1149 * tst_badblocks.c: Use the newer badblocks API names. Add
1150 duplicate blocks to the test inputs to test dealing with
1151 adding blocks which are already in the badblocks list.
1153 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1154 of the list, use a shortcut O(1) operations instead of an
1155 O(n) operation. (Idea suggested by David Beattie.)
1157 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1158 of badblocks_list_free(), to save a procedure call.
1160 1999-10-26 <tytso@valinux.com>
1162 * Release of E2fsprogs 1.17
1164 1999-10-26 <tytso@valinux.com>
1166 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1167 seem to handle ~0UL the same way as they used to.
1169 1999-10-25 <tytso@valinux.com>
1171 * nt_io.c (_OpenNtName): Open the device using
1172 FILE_SYNCHRONOUS_IO_NONALERT instead of

1184 1999-10-22 <tytso@valinux.com>
1186 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1188 * link.c (ext2fs_link): This call now uses the low three bits of
1189 the flags parameter to pass the directory filetype
1190 information; it will set the directory entry FILETYPE
1191 information if the filesystem supports it.
1193 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1194 option is set, then create the '.' and '..' entries with
1195 the filetype set to EXT2_FT_DIR.
1197 1999-09-24 <tytso@valinux.com>
1199 * nt_io.c: New file which supports I/O under Windows NT.
1201 1999-09-07 <tytso@valinux.com>
1203 * ext2fs.h: Add new fields for journalling and define new
1204 feature bits used by newer filesystems: IMAGIC_INODES,
1205 HAS_JOURNAL, RECOVER.
1207 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1208 we update the inode block count and size files so that the
1209 block count field is updated correctly when we create an
1212 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1214 * Release of E2fsprogs 1.15
1216 1999-06-23 <tytso@valinux.com>
1218 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1219 kernels that use i_generation instead of i_version. Patch
1220 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1222 1999-06-21 <tytso@valinux.com>
1224 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1225 directory entry before calling the callback function.
1226 This should prevent some core dumps of insufficiently
1227 paranoid callback functions.
1229 1999-05-29 <tytso@rsts-11.mit.edu>
1231 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1233 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1234 that we don't handle writing yet (we do). Fixed bug where
1235 we weren't allocating a big enough buffer for ext2_bmap.
1237 1999-05-03 <tytso@rsts-11.mit.edu>
1239 * openfs.c (ext2fs_open): Check to make sure that the number of
1240 blocks per group is not zero --- if so, it must be a bad
1243 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1245 * Release of E2fsprogs 1.14
1247 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1249 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1250 the inode number is zero; if it's zero, return
1251 EXT2_ET_BAD_INODE_NUM.
1253 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1255 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1256 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1259 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1261 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1262 non-Linux case to use EINVAL by default, unless it isn't
1263 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1266 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1268 * Release of E2fsprogs 1.13
1270 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1272 * Makefile.in: Updated dependencies.
1274 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1276 * initialize.c (ext2fs_initialize): Make sure that we allocate
1277 enough inodes so that we can make a valid filesystem.
1279 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1281 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1283 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1284 function declaration.
1286 * dblist.c (make_dblist): Add safety check in case the dblist
1287 pointer passed in is null (in which case, assign it to
1288 fs->dblist). Fixed some signed/unsigned warnings.
1290 * bmap.c: Make addr_per_block be of type blk_t to avoid
1291 signed/unsigned warnings.
1293 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1294 function declaration.
1296 * get_pathname.c (get_pathname_proc): Use return value from
1297 ext2fs_get_mem, instead of checking if &gp->name is
1300 * dir_iterate.c (ext2fs_process_dir_block):
1301 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1302 from the function declaration.
1304 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1305 return the error directly instead of jumping to the
1306 cleanup routine, since we don't need to do any cleanup.
1308 * alloc_table.c (ext2fs_allocate_group_table): Make this
1309 function take a dgrp_t for its group argument.
1311 * ext2fs.h: Make dgrp_t an __u32 type, and make
1312 fs->desc_group_count be of type dgrp_t.
1314 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1316 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1317 than 10 blocks when we need to expand the size of the
1320 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1322 * Release of E2fsprogs 1.12
1324 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1326 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1327 appropriate for all of the block group copies, so that
1328 it's clear where the beginning of the filesystem is on the
1329 disk. (For when the partition table gets scrod.)
1331 * ext2fs.h: Change the name of the feature from
1332 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1333 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1335 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1337 * inode.c (get_next_blockgroup): Fix bug where if
1338 get_next_blockgroup() is called early because of a missing
1339 inode table in a block group, the current_inode counter
1340 wasn't incremented correctly.
1342 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1344 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1345 against a completely trashed bad block inode.
1347 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1349 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1350 the stride length hits a bad value, we retry the block
1351 allocation starting at the beginning of the block group.
1353 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1354 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1355 e2_blkcnt_t to avoid collision with LFS API.
1357 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1359 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1360 way that avoids overflows on disk sizes greater than 4GB.
1362 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1364 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1365 return type for comparison functions for qsort.
1367 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1370 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1372 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1375 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1376 evade a potential problem with glibc's header files trying
1377 to spike out linux/types.h.
1379 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1380 include the old size of the memory, which is needed for
1381 some braindamaged memory allocation systems that don't
1384 * badblocks.c (ext2fs_badblocks_list_add):
1385 bb_inode.c (clear_bad_block_proc):

1388 irel_ma.c (ima_put):
1389 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1390 pass the old size of the memory to be resized to
1391 ext2fs_resize_mem().
1393 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1395 * Makefile.in: Change to use new installation directory variables
1396 convention. Fix uninstall rules to take $(DESTDIR) into
1399 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1401 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1402 with 32 bit longs, then we need to manually define __s64
1403 and __u64, since the current kernel header files don't
1404 define these if __STRICT_ANSI__ is defined. This is a
1405 problem if we are compiling with full GCC warnings, since
1406 we do need 64 bit support.
1408 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1409 since we're not using ext2fs_move_blocks() and there
1410 is some question as to its usefulness in its current
1413 * bmap.c (block_bmap): Remove unused function.
1415 * bmove.c (process_block): Fix -Wall warning.
1417 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1419 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1420 contain the offset into the inode.i_blocks array when
1421 ref_block is zero. Since we haven't done a formal
1422 release of e2fsprogs since block_iterate2 was first
1423 introduced, I removed block_iterate2, and renamed
1424 block_iterate3 to be block_iterate2.
1426 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1427 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1428 use of block_iterate and block_iterate2 to
1429 block_iterate2 with the new prototype for the
1430 interator function. (using blkcnt_t forr blockcount)
1432 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1434 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1435 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1436 conditional defines of new features COMPAT_DIR_PREALLOC,
1437 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1438 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1439 the library to declare that we support COMPAT_DIR_PREALLOC,
1440 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1442 * fileio.c: Rename function ext2fs_file_llseek to be
1443 ext2fs_file_lseek, which is more accurate.
1445 * block.c: Add new function ext2fs_block_iterate3 which calls
1446 the iterator function with the blockcount argument of
1447 type blkcnt_t. This version of the function is
1448 allowed to handle large files; the other fucntions are
1451 * ext2fs.h: Add new type blkcnt_t
1453 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1455 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1456 field wasn't getting correctly incremented for sparse
1457 files when the indirect or doubly-indirect block
1458 specified in the inode was zero.
1460 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1462 * unlink.c (unlink_proc):
1463 * lookup.c (lookup_proc):
1464 * link.c (link_proc):
1465 * get_pathname.c (get_pathname_proc):
1466 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1467 from dirent->name_len, so it can be used for other
1470 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1471 and indicate that we have support for this incompatible
1474 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1476 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
1478 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>

1481 number of directories when the block group information is
1484 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1486 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1487 inode table is missing so that we catch the case where the
1488 first block group is missing.
1490 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1493 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1495 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1497 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1499 * test_io.c (test_flush): Add a debugging printf when the flush
1502 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1503 read in, return right away.
1505 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1507 * bitops.h: Don't try to do i386 inline asm functions if the
1510 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1511 instead of linux/types.h, and e2_bitops.h instead of
1514 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1517 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1519 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1520 so that we don't need to call get_next_blockgroup() the
1521 first time around. Saves a bit of time, and prevents us
1522 from needing to assign -1 to current_group (which is an
1525 * icount.c (insert_icount_el): Cast the estimated number of inodes
1526 from a float to an ino_t.
1528 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

1538 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1539 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is

1548 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
1549 make sure the contents of the disk are flushed to disk.
1551 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1565 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1567 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1568 paranoid about validating the directory counts from the
1569 block group information.
1571 * all files: Don't include stdlib.h anymore; include it in
1572 ext2_fs.h, since that file requires stdlib.h
1574 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1576 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1577 bitmap is loaded, and return an error if it is not.
1578 (expand_dir_proc): Only use ext2fs_write_dir_block when

1602 Thu Oct 30 11:33:57 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1604 * Rename new error codes to _ET_ in them for consistency.
1606 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1608 * [all files, basically]: Added definition of ext2fs_get_mem,
1609 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1610 changed all library routines to use these wrapper functions.
1612 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
1613 instead of the system error messages.
1615 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
1618 * ext2fs.h: Added function declarations and constants for bmap.c
1621 * ext2_err.et.in: Added new error messages EXT2_FILE_RO and
1622 EXT2_ET_MAGIC_EXT2_FILE
1624 * Makefile.in: Added files bmap.c and fileio.c, and temporarily
1625 commented out brel_ma.c and irel_ma.c
1627 * bmap.c: New file which maps a file's logical block number to its
1628 physical block number.
1630 * fileio.c: New file which implements simple file reading and
1633 * alloc.c (ext2fs_alloc_block): New function which allocates a
1634 block, zeros it, and updates the filesystem accounting
1635 records appropriately.
1637 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1639 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
1640 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
1641 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
1643 * Change various library files to use these functions instead of
1644 EINVAL, ENOENT, etc.
1646 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1648 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
1649 need to declare llseek().
1651 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1653 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1655 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
1657 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1691 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1693 * io.h: Change the prototype of ext2fs_llseek() to use int's
1694 instead of unsigned int's.
1696 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1697 to make life easer for GNU Libc 2.
1699 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1700 filesystem has its bitmaps stored as 32-bit words with bit
1701 0 as the LSB of each word. Thus a bitmap with only bit 0
1702 set would be, as a string of bytes, 00 00 00 01 00 ... To
1703 cope with this, we byte-reverse each word of a bitmap if
1704 we have a big-endian filesystem, that is, if we are *not*
1705 byte-swapping other word-sized numbers.
1707 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1725 and size_t where appropriate.
1727 * closefs.c (ext2fs_flush): Use dgrp_t instead of int where
1730 * openfs.c (ext2fs_open):
1731 * check_desc.c (ext2fs_check_desc): Use blk_t instead of int where
1734 * rw_bitmaps.c (read_bitmaps):

1737 * initialize.c (ext2fs_initialize):
1738 * brel_ma.c: Fix to make be 16-bit safe.
1740 * link.c (ext2fs_link):

1754 * bb_inode.c (set_bad_block_proc): Add #pragma argsused for Turbo C.
1756 * alloc.c (ext2fs_new_inode): Use ino_t instead of int for the
1759 * get_pathname.c: Use ino_t instead of int where appropriate.
1761 * ext2fs.h: Make the magic structure element be errcode_t instead
1764 * alloc.c alloc_tables.c badblocks.c bb_compat.c bb_inode.c
1765 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
1766 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c
1767 dirblock.c dupfs.c expanddir.c freefs.c get_pathname.c
1768 icount.c initialize.c inline.c inode.c irel_ma.c link.c
1769 llseek.c lookup.c mkdir.c namei.c newdir.c read_bb.c
1770 read_bb_file.c rs_bitmap.c rw_bitmaps.c swapfs.c
1771 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
1772 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
1774 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1776 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1777 is zero, then return EXT2_IO_LLSEEK_FAILED.
1779 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1781 * Release of E2fsprogs 1.11
1783 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1785 * dblist.c (ext2fs_dblist_count): Added new function which returns
1786 the number of directory blocks in dblist.
1788 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1790 * unix_io.c (unix_flush): Make the io_channel flush function do a
1791 fsync to flush the kernel buffers to disk.
1793 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1795 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1796 current inode number wasn't being set by the
1797 goto_blockgroup function.
1799 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1801 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1802 of blocks which need to be moved, and moves those blocks
1803 to another location in the filesystem.
1805 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1806 bitmap, make sure all of the new parts of the bitmap are
1809 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1811 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1812 wasn't being returned to the caller.
1814 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1815 ext2fs_allocate_group_table() which sets the group tables
1816 for a particular block group. The relevant code was
1817 factored out of ext2fs_allocate_tables().
1819 * dblist.c (make_dblist): Adjust the initial size of the directory
1820 block list to be a bit more realistic (ten plus twice the
1821 number of directories in the filesystem).
1823 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1825 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1826 ext2fs_badblocks_list_test would test the list (and exceed
1827 array boundaries) if there were no bad blocks on the bad
1828 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1830 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1832 * Release of E2fsprogs version 1.10
1834 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1836 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1837 inode and block bitmaps based on the RAID 0 stride
1838 parameter (which is passed by mke2fs).
1840 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1841 mke2fs to communicate the stride length to
1842 ext2fs_allocate_tables()
1844 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1846 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1847 systems. (We can't assume that the new filesystem types
1850 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1852 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1853 allocate the inode and block bitmaps inside block group at
1856 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1858 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1859 filesystem has no free blocks, ext2fs_new_block would loop
1862 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1864 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1865 free if refcount goes to zero.
1867 * inode.c (create_icache): Initialize refcount to 1.
1869 * ext2fsP.h: Added refcount to ext2_inode_cache
1871 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
1874 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1875 badblocks structure.
1877 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1879 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
1881 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1883 (unix_close, test_close): Decrement the refcount and only
1884 close the io_channel if the refcount goes to 0.
1886 * io.h: Add refcount to the io_channel structure. Add new macro
1887 interface io_channel_bumpcount() to bump the refcount.
1889 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1891 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1892 cache in the filesystem handle, instead of the inode cache
1893 in a static variable.
1895 * freefs.c: Added static function to free the inode cache (called by
1898 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1900 * ext2fs.h: Added pointer to the inode_cache structure.
1902 * block.c (block_iterate_ind, block_iterate_dind,
1903 block_iterate_tind): If there are holes in the indirect,
1904 doubly indirect, or triply indirect blocks, increment the
1905 block count field automatically.
1907 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1909 * Release of E2fsprogs version 1.09
1911 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1913 * version.c (ext2fs_parse_version_string): Check the passed in
1914 version string (instead of the hard-coded one).
1916 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1917 greater filesystem size, clamp it to prevent allocating a
1918 block or inode bitmap beyond the filesystem.
1920 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1921 overhead calculation was accidentally removed.
1923 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1925 * Release of E2fsprogs version 1.08
1927 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1929 * dblist.c (ext2fs_set_dir_block): New function which sets the
1930 block of a dblist entry, given the directory inode and
1933 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1935 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1936 inode bitmaps at staggered locations across the block
1937 groups, to avoid concentrating the bitmaps on a small
1938 number of disks when using striped RAID arrays.
1940 * initialize.c (ext2fs_initialize): By default, choose the maximum
1941 possible number of blocks per group (based on the size of
1942 the bitmaps in the blocksize).
1944 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1946 * initialize.c (ext2fs_initialize): Add support for
1947 EXT2_COMPAT_SPARSE_SUPER feature.
1949 * closefs.c (ext2fs_bg_has_super): New function to determine
1950 whether or a particular block group should have a
1951 superblock and block group descriptor. Used for the
1952 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1953 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1954 or not the superblock should be written out for the block
1957 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1958 for sparse duplicate superblocks.
1960 * version.c (ext2fs_get_library_version): New function which
1961 returns the library version.
1963 * version.c (ext2fs_parse_version_string): New function which
1964 parses a version string and returns a version number,
1965 so application programs can compare version numbers as
1968 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1970 * icount.c (ext2fs_create_icount): Change function so that it also
1971 takes a new argument which contains a "hint" icount
1972 structure. This "hint" icount allows the create function
1973 to set up the sorted list in advance. This reduces
1974 significantly the amount of data moving needed to insert
1975 these inodes into the list later.
1977 * icount.c (ext2fs_icount_validate): New function which validates
1978 that the icount structure's rep invariant.
1980 * icount.c (get_icount_el): Completely revamped implementation
1981 to subsume put_icount_el(). Put_icount_el() used to
1982 use an O(N) implementation to insert in the middle
1983 of the icount list. It now uses a O(ln N) to search
1984 for where the icount should be inserted, and then uses
1985 a memcpy to move the list down (instead of a for loop).
1987 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1988 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1989 to see if the inode is within bounds; if it isn't, return
1992 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1993 when a bad inode number is passed to test_generic_bitmap
1994 to be EXT2FS_TEST_ERROR instead of the wrong
1995 EXT2FS_UNMARK_ERROR.
1997 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1999 * Release of E2fsprogs version 1.07
2001 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2003 * Makefile.in (ELF_VERSION): Change version to be 2.2
2005 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2007 * alloc.c (ext2fs_get_free_blocks): Change routine to use
2008 ext2fs_fast_test_block_bitmap_range().
2010 * bitops.h (ext2fs_fast_test_block_bitmap_range,
2011 ext2fs_test_block_bitmap_range: New inline functions which
2012 test to see whether a contiguous range of blocks is
2015 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2017 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
2018 use ext2fs_badblocks_* instead of badblocks_*
2020 * bb_compat.c: New file which translates between old badblocks_*()
2021 names to ext2fs_badblocks_*()
2023 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
2024 link.c (since e2fsck doesn't use ext2fs_unlink()).
2026 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
2027 bitmap resizing routine moved from bitmaps.c, since e2fsck
2028 doesn't need to use this function.
2030 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
2031 since e2fsck only needs ext2fs_lookup.
2033 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2035 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
2036 already set; this is needed so that programs like dump
2037 which use the inode scan functions will deal with
2038 filesystems that have bad blocks in the inode table.
2040 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2042 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
2043 Moved to ext2fsP.h, since it doesn't need to be part of
2044 the public interface.
2046 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
2048 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2050 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
2051 directory block list abstraction. (Code moved from
2054 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
2055 to inode.c (since no one else should be peeking inside it!)
2057 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
2059 * openfs.c (ext2fs_open): Check the feature set in the ext2
2060 superblock, and refuse to open filesystems if they contain
2061 incompatible features. (Can be overriden with the
2064 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2066 * block.c (ext2fs_block_iterate2): Added new function
2067 ext2fs_block_iterate2 which changes the function
2068 signature of the callback function to include the
2069 referencing block and offset.
2071 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
2072 ext2fs_inode_scan_goto_blockgroup which allows an
2073 application to jump to a particular block group while
2074 doing an inode scan.
2076 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2078 * dirblock.c: Include string.h, since we use memcpy().
2080 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2082 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2083 a long not an int; this doesn't matter on i386 machines,
2084 but it does on Alpha's.
2086 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2088 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2089 table pointer is NULL, then return an error indicating
2090 that the inode table is missing.
2091 (get_next_blockgroup, get_next_blocks,
2092 ext2fs_get_next_inode): Don't treat a missing inode table
2093 as permanent error. Return MISSING_INODE_TABLE, but as an
2094 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
2096 * rw_bitmaps.c (ext2fs_write_block_bitmap,
2097 ext2fs_write_inode_bitmap): If the inode or block bitmap
2098 block is zero, then don't write out the inode or block
2099 bitmap. The idea here is to avoid stomping on the
2101 (read_bitmaps): If the inode or block bitmap block is
2102 zero, then fill in that portion of the inode or block
2103 bitmap with all zeros.
2105 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
2106 blocks in inode table when the inode table size is
2107 non-standard (and can therefore span blocks).

2111 * alloc.c (ext2fs_new_block): Fix fencepost error in

2117 * inode.c (check_for_inode_bad_blocks): New function called by
2118 get_next_blocks() to avoid reading in bad blocks marked in
2119 fs->badblocks. Inodes located in bad blocks are returned
2120 by ext2fs_get_next_inode() returns the error code
2121 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
2123 * alloc_tables.c (ext2fs_allocate_tables): New function which
2124 performs the part of mke2fs's job of allocating the

2139 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2140 blocks to the badblock list in sorted order. This allows
2141 badblocks_list_test to be coded using a binary search for
2144 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2151 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2154 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2155 set, then only write out the master superblock.

2195 * namei.c (ext2fs_follow_link): New function.
2196 (ext2fs_namei): Extended to have support for chasing
2197 symbolic links. ext2fs_namei() still returns an inode
2198 which is a symbolic link. Symbolic links are only chased
2199 while resolving the containing directory. To chase
2200 symbolic links of the final result, use
2201 ext2fs_follow_link().

2212 * initialize.c (ext2fs_initialize): On systems where the byte
2213 order is not i386 compatible, set the swap_byte flag.
2215 * inode.c (inocpy_with_swap): Check to see if inode contains a
2216 fast symlink before swapping the inode block fields. This
2217 required adding a new argument to inocpy_with_swap to
2218 determine whether the mode field is in host order or not.
2220 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2222 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On

2229 * block.c (ext2fs_block_iterate): Cause block iterator to return
2230 the HURD translator block (along with everything else).

2233 (including the HURD translator).
2235 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2237 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2239 * uuid.c: New file, containing UUID utility functions.

2249 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2251 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2252 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2253 that's a basic value that must be correct for the rest of
2254 the library to work.
2256 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2259 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2270 Change the m68k bit numbering for bitmasks to match with
2271 the bit numbering used by all other ext2 implementations.
2273 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>

2309 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2310 to avoid conflicts with with kernel include files. Also
2311 rename ADDR and CONST_ADDR to EXT2FS_ADDR and

2336 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2339 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2341 * unix_io.c (unix_open): Add a double check; if the passed in name
2342 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2344 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code

2354 partition size from a BSD disk label.
2356 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2358 * getsize.c (ext2fs_get_device_size): New function that determins

2368 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2369 Move these functions to freefs.c.
2371 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2372 descriptors shadow memory to keep purify quiet. (This
2373 also has the nice benefit that the unused portion of the
2374 shadow descriptors are zeroed out.)
2376 * dirblock.c (ext2fs_write_dir_block): We need to use
2377 dirent->rec_len *before* it's byteswapped to find the
2378 location of the next directory structure!
2380 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2381 cause ext2fs_new_inode to loop infinitely if we're trying
2382 to allocate an inode in group #0 and there are no free
2383 inodes at all in the system.
2385 * closefs.c: #include <errno.h> if it exists.
2387 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

2406 file containing functions for reading and writing
2407 directory blocks (byte swapping if necesssary)
2409 * block.c (block_iterate_ind, block_iterate_dind,

2419 the superblock and group descriptors before writing it out.
2421 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2422 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2423 and group descriptors.
2425 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2426 to desp ext2 filesystem structures.
2428 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2429 supplied by Pete A. Zaitcev so that the C language
2430 versions of these functions are more portable. They will
2431 now work on both little and big endian systems, and the
2432 assumption that 32-bit integers are used is gone.
2434 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2435 doing byte swapping.
2437 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

2451 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2452 if the magic number is correct, it will be allocated.
2454 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2456 * block.c (block_iterate_ind, block_iterate_dind,
2457 block_iterate_tind): Don't recompute block_nr each loop;
2458 just increment it! Factor check of BLOCK_FLAG_APPEND out
2459 of the loop. Factor mask of BLOCK_CHANGED into changed
2460 variable out of the loop. (block_iterate_ind, in
2461 particular, gets called a lot, so every little
2462 optimization helps.)
2464 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2466 * block.c (block_iterate_ind, block_iterate_dind,

2478 ext2fs_get_inode_bitmap_end): Add new accessor functions
2479 which return the start and end points of the bitmaps.
2481 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2483 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2484 instead of llseek. The errno if the offset is too large
2485 and lseek is not supported should be EINVAL, not -EINVAL.
2487 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2489 * Makefile.in: Added support for ELF shared libraries.
2490 Fixed typos in the compilation rules.
2491 (distclean): Added Makefile.
2493 * llseek.c (llseek): New function, if llseek() does not exist in the

2505 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2506 the S_*, which are normally defined in <sys/stat.h>. This
2507 allows us to compile e2fsprogs on a non-Linux system,
2508 which may have a different value for S_IFDIR.
2510 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2512 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2513 this is a user-mode application!
2515 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2517 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2518 __linux__ so that non-linux systems won't see it.
2520 * alloc.c: Include <errno.h> if possible.
2521 * badblocks.c: Ditto.
2522 * bb_inode.c: Ditto.
2525 * expanddir.c: Ditto.

2542 * initialize.c (ext2fs_initialize): Don't allow more than one
2543 bitmaps's worth of inodes in a group.
2545 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2547 * llseek.c (ext2_llseek): Added error checking to the llseek()
2548 compat code to protect against overflow. This only
2549 applies to 1.0 and early 1.1 kernels, which don't support
2550 the llseek() system call.
2552 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2554 * unix_io.c (unix_open): Initialize the read_error and write_error
2555 io_channel pointers to be null.
2557 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2558 found, clear it but don't try to update the filesystem
2559 accounting information, since that's hopeless anyway.
2561 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2562 bloblock_iterate_tind): Check to see if the indirect blocks are
2563 valid before trying to read them.

2569 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2570 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2571 illegal block or inode number is passed in, return instead
2572 of trying to test, set, or clear the bit.

2613 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2614 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2615 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2616 * read_bb.c (ext2fs_read_bb_inode):
2617 * read_bb_file.c (ext2fs_read_bb_FILE):
2618 * newdir.c (ext2fs_new_dir_block):
2619 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
2620 * link.c (ext2fs_link, ext2fs_unlink):
2621 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
2622 ext2fs_write_inode, ext2fs_get_blocks,
2623 ext2fs_check_directory):
2624 * get_pathname.c (ext2fs_get_pathname):
2625 * expanddir.c (ext2fs_expand_dir):
2626 * block.c (ext2fs_block_iterate):
2627 * bitmaps.c (ext2fs_allocate_inode_bitmap,
2628 ext2fs_allocate_block_bitmap):
2629 * bb_inode.c (ext2fs_update_bb_inode):
2630 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
2631 * check_desc.c (ext2fs_check_desc):
2632 * closefs.c (ext2fs_close, ext2fs_flush):
2633 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2638 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2639 openfs.c into its own file.
2641 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2642 structure magic numbers.
2644 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2645 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2646 someone uses the -b option to specify the use of the backup
2647 superblock --- this usually means that the main superblock is
2651 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2652 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2653 revision level to the superblock.
2655 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2662 * initialize.c: Completely revamped the inode and block bitmap
2663 structures, so that they can be better chance of being extensible
2664 in a shared library. They are now their own type, instead of
2665 being a char *. Also, the function signatures of
2666 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2667 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2668 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2669 changed to eliminate the ext2_filsys argument, since it is no
2672 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2674 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2675 system call if available.
2677 * llseek.c: new file. This is the stub calling the llseek system
2678 call which allows supports for 2GB+ file systems.
2680 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2681 the creator operating system.
2683 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2685 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2686 the group descriptor statistics in addition to everything else.
2687 This relieves mke2fs of the responsibility of doing it.
2689 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2690 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2691 not the generic C function equivalents should be included or not.
2693 * openfs.c (ext2fs_open): If a superblock is specified, then use
2694 the backup group descriptors that go along with this superblock,
2695 instead of using the primary group descriptors. This allows
2696 e2fsck to recover filesystems where the primary group descriptors
