1 2002-07-23 Theodore Ts'o <tytso@mit.edu>
3 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
4 calculations for names > 32 characters to be completely
5 bogus. Changed MD4 calculation to match what is currently
6 being used in the CVS gkernel tree.
8 2002-07-19 Theodore Ts'o <tytso@mit.edu>
10 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
11 superblock definition.
13 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
14 create a set of u32_list functions.
16 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
17 since that's required by the directory indexing code.
19 2002-07-14 Theodore Ts'o <tytso@mit.edu>
21 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
22 using a C++ reserved word.
24 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
25 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
26 old version of glibc (built against 2.2 headers) will
27 interact badly with the workaround to actually cause more
28 problems. I hate it when the glibc folks think they're
29 being smarter than the kernel....
31 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
33 * ext2_fs.h: Add superblock field for reserved group descriptors.
35 2002-06-28 Theodore Ts'o <tytso@mit.edu>
37 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
38 ext2fs_cpu_to_{l,b}e{32,16}
40 2002-06-27 Theodore Ts'o <tytso@mit.edu>
42 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
43 Add appropriate fallbacks in this case.
45 2002-06-26 Theodore Ts'o <tytso@mit.edu>
47 * dirhash.c (ext2fs_dirhash): Change function signature to support
48 a hash seed, and to return the minor hash (for 64-bit hash
49 support). Add support for the half MD4, half MD4 with
50 seed, and half MD4 with seed and 64 bits.
52 2002-06-15 Theodore Ts'o <tytso@mit.edu>
54 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
56 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
58 * ext2_fs.h: Add macros for maximum block/inode counts:
59 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
60 and EXT2_MAX_INODES_PER_GROUP.
62 * openfs.c (ext2fs_open): Check that the number of blocks in a group
63 is less than 2^16, otherwise we need an INCOMPAT flag (not
64 in existence yet, if ever) to open such a filesystem.
66 * initialize.c (ext2fs_initialize): Limit the number of blocks and
67 inodes in a group to less than 2^16.
69 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
71 * ext2_fs.h: Further minor cleanups of the header. Consolidate
72 some checks for __KERNEL__ into one place.
74 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
76 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
77 the EXT2_SB() macro instead. Remove kernel function
78 prototypes also. This matches the 2.5 kernel, and
79 is also cleaner for other reasons. Whitespace cleanup.
81 2002-05-21 Theodore Ts'o <tytso@mit.edu>
83 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
85 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
87 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
89 * initialize.c (ext2fs_initialize): Remove assumption that
90 blocksizes are always <= 4k.
92 2002-05-11 Theodore Ts'o <tytso@mit.edu>
94 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
95 silently if inode pointer is NULL (and ext2fs_bmap is
96 expected to read the inode itself).
98 2002-04-27 Theodore Ts'o <tytso@mit.edu>
100 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
101 file we are checking is a block device file before looking
102 at st_rdev, since it's not valid for normal files.
103 (is_swap_device): Move so that it is outside the
104 HAVE_MNTENT_H, so that it is always built.
106 2002-03-11 Theodore Tso <tytso@mit.edu>
108 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
109 functions which take an extra flags argument. The flag
110 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
111 field is byte swampped on big-endian machines, since in
112 the V2 structure, name_len is a char field which is
113 doesn't need to be byte swapped --- except if an
114 old-style kernel had byte-swapped the name_len field
115 as part of the V1 structure.
117 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
119 * dirhash.c (ext2fs_dirhash): New function which calculates the
120 hash for a filename in an indexed directory.
122 2002-03-08 Theodore Tso <tytso@mit.edu>
124 * Release of E2fsprogs 1.27
126 2002-03-07 Theodore Tso <tytso@mit.edu>
128 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
130 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
131 tst_byteswap.c: Fix gcc -Wall complaints
133 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
134 (From Philipp Thomas <pthomas@suse.de>)
136 2002-02-25 Theodore Tso <tytso@mit.edu>
138 * ext2_fs.h: Add structure definitions for the directory indexing
141 2002-02-23 Theodore Tso <tytso@mit.edu>
143 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
144 it doesn't break things on mis32, sparc32, and alpha
147 2002-02-21 Theodore Tso <tytso@mit.edu>
149 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
150 we were missing an fclose().
152 2002-02-20 Theodore Tso <tytso@mit.edu>
154 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
155 abstraction interface which exports an ext2 inode.
157 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
158 as a public interface. Change void * to const void * in
159 ext2fs_file_write's interface.
161 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
162 conditional; save a few bytes.
164 2002-02-12 Theodore Tso <tytso@mit.edu>
166 * Makefile.in (tst_badblocks): Add some extra .o files when
167 linking the debugging program tst_badblocks which are
168 needed if we aren't compiling with inline functions enable.
170 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
171 define away __inline__ since it may not be supported.
173 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
174 stripped down jbd_debug that doesn't use variadic
175 arguments. This will cause warnings under AIX, but things
178 2002-02-03 Theodore Tso <tytso@thunk.org>
180 * Release of E2fsprogs 1.26
182 2002-02-03 Theodore Tso <tytso@mit.edu>
184 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
185 so that the number of directories in use is adjusted
188 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
189 which optionally will modify the number of directories
192 2002-01-03 Theodore Tso <tytso@mit.edu>
194 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
195 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
196 which will return deleted directory entries.
197 ext2fs_dir_iterate2 takes a new callback function which
198 is identical with the one used by
199 ext2fs_dblist_dir_iterate(). If the directory entry is
200 deleted, the callback function will be called with the
201 entry paraemter set to DIRENT_DELETED_FILE.
203 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
204 ext2fs_block_alloc_stats): New functions which update
205 block/inode allocation statistics in the bitmaps, block
206 group descriptors, and superblock.
208 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
209 expanddir.c (expand_dir_proc), bb_inode.c
210 (clear_bad_block_proc, set_bad_block_proc,
211 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
212 Update to use new block/inode allocation statistics.
214 2001-12-24 Theodore Tso <tytso@mit.edu>
216 * ismounted.c (is_swap_device): New function used by
217 ext2fs_check_if_mounted and ext2fs_check_mount_point which
218 determines whether or not the specified device is a swap
219 device by using /proc/swaps. More bulletproofing for
220 idiotic/careless system administrators!
222 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
223 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
224 field to struct_ext2_filsys, umask. This field is
225 initialize to 022, and affects ext2fs_mkdir in the obvious
226 way. (In the future umask should also affect new file
227 creation routines, but the fileio functions don't
228 currently support this yes.)
230 * ismounted.c (check_mntent_file): Stat all of the entries in
231 /etc/mtab and/or /proc/mounts in order to catch dim-witted
232 system administrators who might have created alias
235 2001-12-23 Theodore Tso <tytso@mit.edu>
237 * Makefile.in, jfs_user.h: Move linux/jbd.h to
238 ext2fs/kernel-jbd.h, to avoid using the system header
239 file version of hbd.h when using diet glibc (since it
240 forcibly adds /usr/include to the beginning of the
241 include search path.)
243 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
244 include/linux directory.
246 2001-12-16 Theodore Tso <tytso@mit.edu>
248 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
249 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
250 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
252 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
255 2001-12-03 Theodore Tso <tytso@mit.edu>
257 * unix_io.c (unix_open): Make sure the ulimit workaround works
258 regardless of the version of glibc which is used to
261 2001-11-26 Theodore Tso <tytso@mit.edu>
263 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
264 trying to unset the filesize limit if at all possible,
265 if a block device is getting opened. (The filesize limit
266 shouldn't be applied against writes to a block device, but
267 starting in 2.4.10, the kernel is doing this.)
269 2001-11-05 Theodore Tso <tytso@mit.edu>
271 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
272 file on adding a journal to an already-mounted filesystem,
273 try to clear the ext2 file attributes on an already
274 existing .journal file so that we don't fail if on a
275 partially added journal to the filesystem.
277 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
278 which signals that a particular inode should not have the
279 last bits of data (the "tail") be merged with another
280 file. This is necessary to keep LILO happy.
282 2001-09-20 Theodore Tso <tytso@thunk.org>
284 * Release of E2fsprogs 1.25
286 2001-09-16 Theodore Tso <tytso@mit.edu>
288 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
289 which was breaking the build on the Hurd. (Addresses
292 2001-09-13 Theodore Ts'o <tytso@mit.edu>
294 * ismounted.c (check_mntent_file): We now validate the entry in
295 /etc/mtab to make sure the filesystem is really mounted,
296 since some broken distributions (read: Slackware) have
297 buggy boot scripts that don't initialize /etc/mtab before
298 checking non-root filesystems. (Slackware also doesn't
299 check the root filesystem separately, and reboot if the
300 root filesystem had changes applied to it, which is
301 dangerous and broken.)
303 2001-09-02 Theodore Tso <tytso@thunk.org>
305 * Release of E2fsprogs 1.24a
307 2001-08-30 Theodore Tso <tytso@thunk.org>
309 * Release of E2fsprogs 1.24
311 2001-08-30 Theodore Tso <tytso@valinux.com>
313 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
314 changes, since the ioctl number has been reused by another
317 2001-08-15 Theodore Tso <tytso@valinux.com>
319 * Release of E2fsprogs 1.23
321 2001-08-05 Theodore Tso <tytso@valinux.com>
323 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
324 version of the bitmap test routines to speed up these
325 routines. (At some point I may want to make these
326 routines use the find_first_bit functions, but that will
327 add a lot of complexity since it means that these
328 functions will have to break the bitmap abstraction
329 boundary. It's not clear it's worth it.)
331 * mkjournal.c (mkjournal_proc): Remember the last block allocated
332 to speed up ext2fs_new_block().
334 2001-07-29 Theodore Tso <tytso@valinux.com>
336 * finddev.c (scan_dir): Fix memory leak; we weren't calling
337 closedir() when exiting the function in all cases.
339 2001-07-27 Theodore Tso <tytso@valinux.com>
341 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
342 block usable in the journal for external journals to be 2
343 or 3, depending on the blocksize, so that the existing
344 kernel code does the right thing.
346 * getsize.c (ext2fs_get_device_size): Add support for the
347 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
348 from Ben LaHaise, but it's likely this interface won't
351 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
352 when writing the journal superblock, too. (Oops! Needed
353 to make 1k filesystems with external journal to work.)
355 2001-07-26 Theodore Tso <tytso@valinux.com>
357 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
358 to find the journal superblock if the blocksize is 1024.
360 2001-07-21 Theodore Tso <tytso@valinux.com>
362 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
364 2001-07-20 Theodore Tso <tytso@valinux.com>
366 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
367 attribute block, set the filesystem changed bit.
369 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
370 Comment out these functions since we're not using them.
372 2001-07-10 Theodore Tso <tytso@valinux.com>
374 * closefs.c (write_primary_superblock): After writing changes to
375 the primary superblock, update the original superblock
376 copy so we don't have to re-write those changes in the
378 (ext2fs_flush): Clear the superblock dirty flag after
379 we've flushed out changes to disk.
381 2001-07-07 Theodore Tso <tytso@valinux.com>
383 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
384 to avoid register conflicts when compiling in PIC mode.
386 2001-07-04 Theodore Tso <tytso@valinux.com>
388 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
389 Add new functions (C and in i386 assembler) which quickly
390 find bits set in a bitmask.
392 2001-06-23 Theodore Tso <tytso@valinux.com>
394 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
395 ext2_ext_attr.h and ext_attr.c for extended attributes
398 * Release of E2fsprogs 1.22
400 2001-06-22 Theodore Tso <tytso@valinux.com>
402 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
403 descriptor so that adding a journal to a mounted
404 filesystem doesn't die. (Fixes a bug accidentally
405 introduced in e2fsprogs 1.21.)
407 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
408 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
409 fchflags without defining UF_NODUMP. (Addresses Debian
412 * flushb.c: Use platform independent method of defining the
413 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
414 since on newer glibc's BLKFLSBUF is defined there.
416 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
417 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
418 to support byte swapping even if we don't support the
419 conversion functions. (Fixes Debian bug #101686).
421 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
422 since the byte-swapping code all assumes the
423 ext2_dir_entry structure. (It's a question of whether or
424 not name_len should be byte-swapped or not, and whether
425 it's a 16 bit or 8 bit field.)
427 2001-06-15 Theodore Tso <tytso@valinux.com>
429 * Release of E2fsprogs 1.21
431 2001-06-15 Theodore Tso <tytso@valinux.com>
433 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
434 file which is generated and is therefore found in the
435 build directory, not source directory.
437 * ismounted.c (check_mntent_file): Use a test file in / to check
438 to see if the root filesystem is mounted read-only. This
439 protects against the case where /etc might not be on /, as
440 well as the case where /etc/mtab doesn't exist. (Both are
441 should-never happen scenarios, but you never know...)
443 2001-06-14 Theodore Tso <tytso@valinux.com>
445 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
446 Remove unneeded #pragma argsused, since the arguments are
449 2001-06-13 Theodore Tso <tytso@valinux.com>
451 * ext2_types.h.in: If linux/types.h has been defined, then don't
452 try to redefine the typedefs.
454 * Makefile.in (HFILES): Add ext2_types.h to the list of files
455 which should be installed.
457 * ismounted.c (check_mntent_file): Work around GNU hurd brain
458 damage. Addresses Debian bug #100304.
460 * Makefile.in: Limit some .o files from being included into the
461 library if --disable-debugfs, --disable-swapfs,
462 --disable-imager, or --disable-resizer are used.
464 2001-06-12 Theodore Tso <tytso@valinux.com>
466 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
467 function, and use the ext2fs_badblocks_* functions
470 2001-06-11 Theodore Tso <tytso@valinux.com>
472 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
473 ext2fs_mark_generic_bitmap and
474 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
475 functions. (This saves space and doesn't significantly
476 change the speed of e2fsck on a P-III.)
478 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
479 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
480 include the byte-swapping logic if ENABLE_SWAPFS is turned
481 on or if we're on a big-endian machine.
483 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
484 set EXT2_FLAG_SWAP_BYTES, instead of using
487 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
488 autoconf to determine whether or not return
489 EXT2_FLAG_SWAP_BYTES.
491 2001-06-10 Theodore Tso <tytso@valinux.com>
493 * Makefile.in: Remove the dependence on the libe2p library.
495 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
496 with direct usage of the ioctl/fchflags so that we don't
497 have to depend on the libe2p library.
499 2001-06-08 Theodore Tso <tytso@valinux.com>
501 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
502 when trying to find a 32-bit wide type.
504 * icount.c (insert_icount_el): Fix the code used to estimate the
505 size of the new icount array to be more intelligent, to
506 avoid reallocating the array too many times. Thanks to
507 Enrique Perez-Terron for pointing this out.
509 2001-06-02 Theodore Tso <tytso@valinux.com>
511 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
512 for a symlink to determine whether it is a fast symlink.
514 2001-06-01 Theodore Tso <tytso@valinux.com>
516 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
517 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
519 2001-05-25 Theodore Tso <tytso@valinux.com>
521 * Release of E2fsprogs 1.20
523 2001-05-25 Theodore Tso <tytso@valinux.com>
525 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
526 some to clean up Andreas's patches. Use strncpy instead
527 of strcpy to save the root's mountpoint. Clean up #ifdef
528 structure. Remove uneeded variable in testing/debug driver.
530 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
532 * ismounted.c: Add check for root device which doesn't depend on
533 /etc/fstab or /proc/mounts to be correct. Don't call
534 endmntent() before we are done with mnt struct.
536 2001-05-23 Theodore Tso <tytso@valinux.com>
538 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
541 2001-05-21 Theodore Tso <tytso@valinux.com>
543 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
544 make room for pre-existing usage of
545 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
546 the same codepoint as EXT2_BTREE_FL.
548 2001-05-20 Theodore Tso <tytso@valinux.com>
550 * ext2fs.h: #include <> instead of "" for ext2fs and et header
551 files, since they will be installed in /usr/include
553 2001-05-14 Theodore Tso <tytso@valinux.com>
555 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
556 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

566 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
567 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
568 Adjust all files in this directroy to include this file.
570 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
573 2001-05-05 Theodore Tso <tytso@valinux.com>
575 * fileio.c (ext2fs_file_read): Factored out common code and
576 cleaned up function. Fixed a bug where if there was an
577 error reading from the disk, the number of bytes read
578 wasn't reliably set. (Fixes Debian bug #79163)
579 (ext2fs_file_write): Factored out common code and made
580 function more efficient; if writing a full block, don't
581 bother to do a read-modify-write cycle.
583 2001-05-04 Theodore Tso <tytso@valinux.com>
585 * dirblock.c (ext2fs_read_dir_block): Check for an directory
586 record length which isn't a multiple four, and treat that
587 as an invalid. Scan the directory and return an error
588 (EXT2_ET_DIR_CORRUPTED) if the directory records are
590 (ext2fs_write_dir_block): If while byte-swapping the
591 directory block, if there's an error, abort and return
592 EXT2_ET_DIR_CORRUPTED.
594 2001-05-02 Theodore Tso <tytso@valinux.com>
596 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
597 image_header field in the ext2_filsys structure
599 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
600 * inode.c (ext2fs_read_inode):
601 * rw_bitmaps.c (read_bitmaps):
602 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
604 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
605 sure the full bitmap is saved.
607 2001-05-01 Theodore Tso <tytso@valinux.com>
609 * e2image.h (struct ext2_image_hdr): Add space for the device name
612 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
613 make sure the rec_len is a multiple of 4, to prevent
614 bus-errors on architectures which care about mis-aligned
617 2001-04-25 Theodore Tso <tytso@valinux.com>
619 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
620 query the device sizes using the BLKGETSIZE ioctl.
622 2001-04-16 Theodore Tso <tytso@valinux.com>
624 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
625 before checking /etc/mtab. The EXT2_MF_READONLY flag is
626 now set from the /etc/mtab options field for all
627 filesystems, not just the root filesystem. Add debugging
628 code to make it easier to test ext2fs_check_if_mounted().
630 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
631 check; return an error if there's an attempt to create a
632 journal less than 1024 filesystem blocks.
634 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
635 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
637 2001-02-20 Theodore Tso <tytso@valinux.com>
639 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
642 * tst_byteswap.c: New function to test the byteswap functions.
643 Add to regression test suite.
645 2001-02-08 Theodore Tso <tytso@valinux.com>
647 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
649 2001-02-07 Theodore Tso <tytso@valinux.com>
651 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
652 of s_first for external devices to always be 1, since
653 jsb->s_first is always relative to the start of the
654 journal superblock. Use htonl(1) when setting s_nr_users.
656 2001-01-17 Theodore Ts'o <tytso@valinux.com>
658 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
659 device number of the filesystem (instead of the journal)
660 was being dropped into s_journal_dev.
662 2001-01-15 Theodore Ts'o <tytso@valinux.com>
664 * initialize.c (ext2fs_initialize): Add support for initializing
665 the ext2 superblock for external journal devices. This
666 basically means we don't bother to allocate any block
669 * openfs.c (ext2fs_open): Only open external journal devices if
670 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
671 ext2fs_open. When opening such devices, don't try to read
672 the block group descriptors, since they're not there.
674 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
676 * mkjournal.c: Export a new function,
677 ext2fs_create_journal_superblock(), which allocates and
678 returns a buffer containing a journal superblock. This is
679 needed by mke2fs to create an external journal. Rewrote
680 ext2fs_add_journal_device() so that it no longer creates
681 the external journal, but rather adds a filesystem to an
682 existing external journal. It handles all of the UUID
685 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
686 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
687 Changed function prototype for ext2fs_add_journal_device().
689 2001-01-14 Theodore Ts'o <tytso@valinux.com>
691 * closefs.c (ext2fs_flush): Don't write out anything beyond the
692 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
695 2001-01-12 Theodore Ts'o <tytso@valinux.com>
697 * imager.c: Fix gcc -Wall complaints and a series of bugs where
698 retval wasn't set correctly. (Thanks to Andreas Dilger
699 for pointing this out.)
701 2001-01-11 <tytso@snap.thunk.org>
703 * flushb.c (ext2fs_sync_device): New function which centralizes
704 all of the places which might try to use the BLKFLSBUF
705 or FDFLUSH ioctls (and usually failing to define them
706 since the system header files don't usually do this for
707 us, and we're trying to avoid usage of kernel include
710 2001-01-10 <tytso@snap.thunk.org>
712 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
713 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
714 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
715 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
716 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
717 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
718 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
719 ext2_ino_t, to protect applications that attempt to
720 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
721 changes ino_t(!?). So we use ext2_ino_t to avoid an
722 unexpected ABI change.
724 2001-01-05 <tytso@snap.thunk.org>
726 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
727 we may overrun allocated memory in case of a corrupted
728 filesystem (or an e2fsck test case :-) when byte-swapping
731 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
733 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
734 complaints including a missing return 0 at the end of
735 ext2fs_add_journal_device.
737 2001-01-03 <tytso@snap.thunk.org>
739 * Makefile.in: Link in libe2p when creating libext2fs as a shared
740 library, since mkjournal.c now references fsetflags().
742 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
743 Dilger's changes (with fixups) to allow on-line creation
746 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
747 EXT2_FLAG_SUPER_ONLY, which the close routines to only
748 update the superblock, and not the group descriptors.
750 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
752 * ismounted.c: add ext2fs_check_mount_point() function, which will
753 optionally return the mount point of a device if mounted
755 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
757 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
758 ext2fs_add_journal_inode()
760 2001-01-01 <tytso@snap.thunk.org>
762 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
763 source (but not binary) compatibility of some users of the
764 ext2 library. They should just simply do a global search
765 and replace of struct ext2fs_sb with struct
766 ext2_super_block, and use their own private copy of
767 ext2_fs.h if they aren't already.
769 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
770 Replace use of ext2fs_sb with ext2_super_block.
772 2000-12-31 <tytso@snap.thunk.org>
774 * ext2fs.h: Cleaned up header file by removing definitions of
775 feature flags that might not have been defined in older
776 ext2 header files. Now that we're using our own
777 include/linux/ext2fs.h header file, this can never happen.
779 * jfs_dat.h: Removed old header file which is no longer needed.
781 2000-12-13 Theodore Ts'o <tytso@valinux.com>
783 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
784 by Andreas Dilger to update the filesystem revision to
787 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
790 2000-12-09 <tytso@snap.thunk.org>
792 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
793 ext2fs_add_journal_device): Add a new argument to the APIs
794 of these function, which is a flags word. This is used to
795 allow the creation of a V1 superblock for those folks who
796 are using ext3 0.3b in production. Note, the user-land
797 interface for getting at this flag won't be documented, as
798 the V1 superblock is deprecated.
800 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
801 which creates a V2 superblock instead of a V1 superblock.
803 2000-11-21 <tytso@snap.thunk.org>
805 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
806 out by Andreas Dilger.
808 2000-11-05 <tytso@snap.thunk.org>
810 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
811 ext2_fs.h, Makefile.in: New file that has routines that
812 save ext2fs metadata to a file.
814 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
816 * e2image.h: New file which defines the file format for the ext2
817 image file. (Saved copy of ext2 metadata to a file as a
818 saving throw against worst-case damage.)
820 2000-11-01 <tytso@snap.thunk.org>
822 * inode.c (ext2fs_flush_icache): Add new function
823 ext2fs_flush_icache() which flushes the internal inode
824 cache. Applications which modify the inode table blocks
825 directly must call this function.
827 2000-10-26 <tytso@snap.thunk.org>
829 * mkjournal.c: Add #include of netinet/in.h, since Solaris
830 requires it for ntohl().
832 * ext2_io.h (io_channel_write_byte): Add new interface to allow
833 callers to write specific byte ranges. This is an
834 optional interface, which not all IO channels may
837 * unix_io.c (unix_write_byte):
838 * test_io.c (test_write_byte): Add implementation of the
841 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
842 function which writes the primary superblock. If the IO
843 channel supports writing raw bytes directly, only fields
844 which were modified are written to the disk. This makes
845 it safe(r) to use utilities like tune2fs on a mounted
848 * freefs.c (ext2fs_free): Free the original superblock if it is
851 * openfs.c (ext2fs_open): Store a copy of the original superblock
854 * ext2fs.h: Add a field to store the original superblock in the
855 ext2 context structure.
857 2000-10-24 <tytso@snap.thunk.org>
859 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
860 don't need to use llseek).
862 2000-10-24 <tytso@valinux.com>
864 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
865 creating an ext3 journal on a filesystem.
867 2000-08-21 <tytso@valinux.com>
869 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
871 2000-08-22 <tytso@valinux.com>
873 * unix_io.c: Make massive changes to support a multiple block
874 writethrough cacheing.
876 * ext2_io.h: Added flags field to the io_channel structure.
878 2000-08-19 <tytso@valinux.com>
880 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
881 provides the function ext2fs_find_block_device(). This
882 function returns the pathname to a block device, given its
885 2000-07-13 <tytso@valinux.com>
887 * Release of E2fsprogs 1.19
889 2000-07-07 Theodore Ts'o <tytso@valinux.com>
891 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
892 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
893 list of filesystem flags supported by the library.
895 2000-07-04 Theodore Ts'o <tytso@valinux.com>
897 * ext2fs.h: Update to include latest journalling additions to the
900 * dll/jump.funcs: Add new jumptable entries for
901 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
902 ext2fs_badblocks_equal.
904 * tst_badblocks.c: Update test program to test
905 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
907 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
908 writes out bad blocks list to a file.
910 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
911 changes the callback function to take two additional
912 arguments; a private blind pointer supplied by the caller,
913 and pointer to a char * containing a pointer to the
916 * badblocks.c (ext2fs_badblocks_equal): Add new function which
917 returns true if two badblocks list are equal.
919 * Makefile.in: Remove explicit link of -lc in the shared library.
920 (It shouldn't be necessary, and is harmful in some cases).
922 2000-06-10 Theodore Ts'o <tytso@valinux.com>
924 * getsize.c (main): Add debugging code under #ifdef DEBUG
926 2000-05-27 Theodore Ts'o <tytso@valinux.com>
928 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
929 earlier, so that if there's an error reading it, we can
930 more cleanly back out of the operation.
932 2000-05-25 <tytso@snap.thunk.org>
934 * getsize.c (ext2fs_get_device_size): Use open64() instead of
935 open() if it exists. Under linux, manually define the
936 ioctl for BLKGETSIZE if it isn't already defined and it's
939 * unix_io.c (unix_open): Use open64() instead of open() if it
942 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
943 available (and prototypes are defined) use it in
944 preference to llseek.
946 * Makefile: Add hack dependency rule so that parallel makes work
949 2000-05-18 Theodore Ts'o <tytso@valinux.com>
951 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
953 2000-04-03 Theodore Ts'o <tytso@valinux.com>
955 * block.c: Readibility tweak in conditionals involving
958 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
959 how to define __s64 and __u64. Turn off "compression is
960 experimental" warning if the cpp macro
961 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
963 2000-02-11 <tytso@snap.thunk.org>
965 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
966 Conditionally include Compression as a supported type if
967 ENABLE_COMPRESSION (via --enable-compression) is turned on.
969 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
971 2000-02-08 <tytso@snap.thunk.org>
973 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
974 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
975 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
976 Change to return the previous state of the bit that is
977 being marked or unmarked. For speed optimization.
979 2000-02-02 Theodore Ts'o <tytso@valinux.com>
981 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
983 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
984 needed any more; we know it will always be i_generation.
985 Add support for swapping the high bits of the uid and gid.
987 1999-11-19 <tytso@valinux.com>
989 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
990 counts if the link was successful. Patch suggested by
993 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
994 the source directory.
996 1999-11-10 <tytso@valinux.com>
998 * Release of E2fsprogs 1.18
1000 1999-11-08 <tytso@valinux.com>
1002 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1003 since ext2fs_badblocks_list_free was moved to freefs.c.
1005 * tst_badblocks.c: Use the newer badblocks API names. Add
1006 duplicate blocks to the test inputs to test dealing with
1007 adding blocks which are already in the badblocks list.
1009 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1010 of the list, use a shortcut O(1) operations instead of an
1011 O(n) operation. (Idea suggested by David Beattie.)
1013 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1014 of badblocks_list_free(), to save a procedure call.
1016 1999-10-26 <tytso@valinux.com>
1018 * Release of E2fsprogs 1.17
1020 1999-10-26 <tytso@valinux.com>
1022 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1023 seem to handle ~0UL the same way as they used to.
1025 1999-10-25 <tytso@valinux.com>
1027 * nt_io.c (_OpenNtName): Open the device using
1028 FILE_SYNCHRONOUS_IO_NONALERT instead of
1029 FILE_SYNCHRONOUS_IO_ALERT
1030 (nt_open): At the end of the device open routine, unlock
1031 the drive but do not dismount it.
1033 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
1036 1999-10-22 <tytso@valinux.com>
1038 * Release of E2fsprogs 1.16
1040 1999-10-22 <tytso@valinux.com>
1042 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1044 * link.c (ext2fs_link): This call now uses the low three bits of
1045 the flags parameter to pass the directory filetype
1046 information; it will set the directory entry FILETYPE
1047 information if the filesystem supports it.
1049 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1050 option is set, then create the '.' and '..' entries with
1051 the filetype set to EXT2_FT_DIR.
1053 1999-09-24 <tytso@valinux.com>
1055 * nt_io.c: New file which supports I/O under Windows NT.
1057 1999-09-07 <tytso@valinux.com>
1059 * ext2fs.h: Add new fields for journalling and define new
1060 feature bits used by newer filesystems: IMAGIC_INODES,
1061 HAS_JOURNAL, RECOVER.
1063 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1064 we update the inode block count and size files so that the
1065 block count field is updated correctly when we create an
1068 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1070 * Release of E2fsprogs 1.15
1072 1999-06-23 <tytso@valinux.com>
1074 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1075 kernels that use i_generation instead of i_version. Patch
1076 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1078 1999-06-21 <tytso@valinux.com>
1080 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1081 directory entry before calling the callback function.
1082 This should prevent some core dumps of insufficiently
1083 paranoid callback functions.
1085 1999-05-29 <tytso@rsts-11.mit.edu>
1087 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1089 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1090 that we don't handle writing yet (we do). Fixed bug where
1091 we weren't allocating a big enough buffer for ext2_bmap.
1093 1999-05-03 <tytso@rsts-11.mit.edu>
1095 * openfs.c (ext2fs_open): Check to make sure that the number of
1096 blocks per group is not zero --- if so, it must be a bad
1099 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1101 * Release of E2fsprogs 1.14
1103 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1105 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1106 the inode number is zero; if it's zero, return
1107 EXT2_ET_BAD_INODE_NUM.
1109 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1111 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1112 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1115 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1117 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1118 non-Linux case to use EINVAL by default, unless it isn't
1119 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1122 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1124 * Release of E2fsprogs 1.13
1126 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1128 * Makefile.in: Updated dependencies.
1130 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1132 * initialize.c (ext2fs_initialize): Make sure that we allocate
1133 enough inodes so that we can make a valid filesystem.
1135 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1137 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1139 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1140 function declaration.
1142 * dblist.c (make_dblist): Add safety check in case the dblist
1143 pointer passed in is null (in which case, assign it to
1144 fs->dblist). Fixed some signed/unsigned warnings.
1146 * bmap.c: Make addr_per_block be of type blk_t to avoid
1147 signed/unsigned warnings.
1149 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1150 function declaration.
1152 * get_pathname.c (get_pathname_proc): Use return value from
1153 ext2fs_get_mem, instead of checking if &gp->name is
1156 * dir_iterate.c (ext2fs_process_dir_block):
1157 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1158 from the function declaration.
1160 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1161 return the error directly instead of jumping to the
1162 cleanup routine, since we don't need to do any cleanup.
1164 * alloc_table.c (ext2fs_allocate_group_table): Make this
1165 function take a dgrp_t for its group argument.
1167 * ext2fs.h: Make dgrp_t an __u32 type, and make
1168 fs->desc_group_count be of type dgrp_t.
1170 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1172 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1173 than 10 blocks when we need to expand the size of the
1176 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1178 * Release of E2fsprogs 1.12
1180 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1182 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1183 appropriate for all of the block group copies, so that
1184 it's clear where the beginning of the filesystem is on the
1185 disk. (For when the partition table gets scrod.)
1187 * ext2fs.h: Change the name of the feature from
1188 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1189 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1191 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1193 * inode.c (get_next_blockgroup): Fix bug where if
1194 get_next_blockgroup() is called early because of a missing
1195 inode table in a block group, the current_inode counter
1196 wasn't incremented correctly.
1198 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1200 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1201 against a completely trashed bad block inode.
1203 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1205 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1206 the stride length hits a bad value, we retry the block
1207 allocation starting at the beginning of the block group.
1209 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1210 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1211 e2_blkcnt_t to avoid collision with LFS API.
1213 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1215 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1216 way that avoids overflows on disk sizes greater than 4GB.
1218 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1220 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1221 return type for comparison functions for qsort.
1223 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1226 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1228 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1231 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1232 evade a potential problem with glibc's header files trying
1233 to spike out linux/types.h.
1235 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1236 include the old size of the memory, which is needed for
1237 some braindamaged memory allocation systems that don't
1240 * badblocks.c (ext2fs_badblocks_list_add):
1241 bb_inode.c (clear_bad_block_proc):

1245 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1246 pass the old size of the memory to be resized to
1247 ext2fs_resize_mem().
1249 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1251 * Makefile.in: Change to use new installation directory variables
1252 convention. Fix uninstall rules to take $(DESTDIR) into
1255 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1257 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1258 with 32 bit longs, then we need to manually define __s64
1259 and __u64, since the current kernel header files don't
1260 define these if __STRICT_ANSI__ is defined. This is a
1261 problem if we are compiling with full GCC warnings, since
1262 we do need 64 bit support.
1264 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1265 since we're not using ext2fs_move_blocks() and there
1266 is some question as to its usefulness in its current
1269 * bmap.c (block_bmap): Remove unused function.
1271 * bmove.c (process_block): Fix -Wall warning.
1273 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1275 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1276 contain the offset into the inode.i_blocks array when
1277 ref_block is zero. Since we haven't done a formal
1278 release of e2fsprogs since block_iterate2 was first
1279 introduced, I removed block_iterate2, and renamed
1280 block_iterate3 to be block_iterate2.
1282 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1283 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1284 use of block_iterate and block_iterate2 to
1285 block_iterate2 with the new prototype for the
1286 interator function. (using blkcnt_t forr blockcount)
1288 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1290 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1291 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1292 conditional defines of new features COMPAT_DIR_PREALLOC,
1293 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1294 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1295 the library to declare that we support COMPAT_DIR_PREALLOC,
1296 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1298 * fileio.c: Rename function ext2fs_file_llseek to be
1299 ext2fs_file_lseek, which is more accurate.
1301 * block.c: Add new function ext2fs_block_iterate3 which calls
1302 the iterator function with the blockcount argument of
1303 type blkcnt_t. This version of the function is
1304 allowed to handle large files; the other fucntions are
1307 * ext2fs.h: Add new type blkcnt_t
1309 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1311 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1312 field wasn't getting correctly incremented for sparse
1313 files when the indirect or doubly-indirect block
1314 specified in the inode was zero.
1316 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1318 * unlink.c (unlink_proc):
1319 * lookup.c (lookup_proc):
1320 * link.c (link_proc):
1321 * get_pathname.c (get_pathname_proc):
1322 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1323 from dirent->name_len, so it can be used for other
1326 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1327 and indicate that we have support for this incompatible
1330 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1332 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
1334 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1336 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
1337 number of directories when the block group information is
1340 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1342 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1343 inode table is missing so that we catch the case where the
1344 first block group is missing.
1346 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1349 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1351 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1353 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1355 * test_io.c (test_flush): Add a debugging printf when the flush
1358 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1359 read in, return right away.
1361 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1363 * bitops.h: Don't try to do i386 inline asm functions if the
1366 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1367 instead of linux/types.h, and e2_bitops.h instead of
1370 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1373 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1375 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1376 so that we don't need to call get_next_blockgroup() the
1377 first time around. Saves a bit of time, and prevents us
1378 from needing to assign -1 to current_group (which is an
1381 * icount.c (insert_icount_el): Cast the estimated number of inodes
1382 from a float to an ino_t.
1384 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
1385 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1386 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

1394 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1395 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
1396 defined, then assume all of the
1397 ext2-specific header files are in a flat directory.
1399 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1400 all assignments from void * to be compatible with C++.
1402 Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1404 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
1405 make sure the contents of the disk are flushed to disk.
1407 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1409 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
1410 avoid C++ namespace clash.
1412 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
1413 avoid C++ namespace clash.
1415 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
1416 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
1417 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
1418 unlink.c: Change private to be priv_data (to avoid C++
1421 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1423 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1424 paranoid about validating the directory counts from the
1425 block group information.
1427 * all files: Don't include stdlib.h anymore; include it in
1428 ext2_fs.h, since that file requires stdlib.h
1430 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1432 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1433 bitmap is loaded, and return an error if it is not.
1434 (expand_dir_proc): Only use ext2fs_write_dir_block when
1435 writing a directory block, not when writing out a fresh
1438 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1462 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1464 * [all files, basically]: Added definition of ext2fs_get_mem,
1465 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1466 changed all library routines to use these wrapper functions.

1486 * fileio.c: New file which implements simple file reading and
1489 * alloc.c (ext2fs_alloc_block): New function which allocates a
1490 block, zeros it, and updates the filesystem accounting

1509 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1511 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
1513 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1517 * icount.c (ext2fs_icount_validate):
1518 * bmove.c (process_block): Fix lint error in type for fprintf().
1520 Mon Sep 15 11:45:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1522 * inode.c (ext2fs_check_directory): Add support for the callback
1523 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
1525 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1527 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
1528 padding of the bitmap to be all one's.
1530 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
1532 * llseek.c: Added missing semicolon to glibc fixup declaration of
1535 * bmove.c: Add #include of errno.h
1537 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1539 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
1540 added a new field to the io_channel (app_data).
1542 * io.h: Add a new element to the io_channel structure, app_data.
1544 * initialize.c, openfs.c: Set io->app_data to point at the

1549 * io.h: Change the prototype of ext2fs_llseek() to use int's
1550 instead of unsigned int's.
1552 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1553 to make life easer for GNU Libc 2.
1555 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1556 filesystem has its bitmaps stored as 32-bit words with bit
1557 0 as the LSB of each word. Thus a bitmap with only bit 0
1558 set would be, as a string of bytes, 00 00 00 01 00 ... To
1559 cope with this, we byte-reverse each word of a bitmap if
1560 we have a big-endian filesystem, that is, if we are *not*
1561 byte-swapping other word-sized numbers.
1563 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1581 and size_t where appropriate.
1583 * closefs.c (ext2fs_flush): Use dgrp_t instead of int where
1586 * openfs.c (ext2fs_open):
1587 * check_desc.c (ext2fs_check_desc): Use blk_t instead of int where

1630 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1632 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1633 is zero, then return EXT2_IO_LLSEEK_FAILED.
1635 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1637 * Release of E2fsprogs 1.11
1639 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1641 * dblist.c (ext2fs_dblist_count): Added new function which returns
1642 the number of directory blocks in dblist.
1644 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1646 * unix_io.c (unix_flush): Make the io_channel flush function do a
1647 fsync to flush the kernel buffers to disk.
1649 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1651 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1652 current inode number wasn't being set by the
1653 goto_blockgroup function.
1655 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1657 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1658 of blocks which need to be moved, and moves those blocks
1659 to another location in the filesystem.
1661 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1662 bitmap, make sure all of the new parts of the bitmap are
1665 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1667 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1668 wasn't being returned to the caller.
1670 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1671 ext2fs_allocate_group_table() which sets the group tables
1672 for a particular block group. The relevant code was
1673 factored out of ext2fs_allocate_tables().
1675 * dblist.c (make_dblist): Adjust the initial size of the directory
1676 block list to be a bit more realistic (ten plus twice the
1677 number of directories in the filesystem).
1679 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1681 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1682 ext2fs_badblocks_list_test would test the list (and exceed
1683 array boundaries) if there were no bad blocks on the bad
1684 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1686 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1688 * Release of E2fsprogs version 1.10
1690 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1692 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1693 inode and block bitmaps based on the RAID 0 stride
1694 parameter (which is passed by mke2fs).
1696 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1697 mke2fs to communicate the stride length to
1698 ext2fs_allocate_tables()
1700 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1702 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1703 systems. (We can't assume that the new filesystem types
1706 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1708 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1709 allocate the inode and block bitmaps inside block group at
1712 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1714 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1715 filesystem has no free blocks, ext2fs_new_block would loop
1718 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1720 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1721 free if refcount goes to zero.

1737 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1739 (unix_close, test_close): Decrement the refcount and only
1740 close the io_channel if the refcount goes to 0.
1742 * io.h: Add refcount to the io_channel structure. Add new macro
1743 interface io_channel_bumpcount() to bump the refcount.
1745 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1747 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1748 cache in the filesystem handle, instead of the inode cache
1749 in a static variable.
1751 * freefs.c: Added static function to free the inode cache (called by
1754 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1756 * ext2fs.h: Added pointer to the inode_cache structure.
1758 * block.c (block_iterate_ind, block_iterate_dind,
1759 block_iterate_tind): If there are holes in the indirect,
1760 doubly indirect, or triply indirect blocks, increment the
1761 block count field automatically.
1763 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1765 * Release of E2fsprogs version 1.09
1767 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1769 * version.c (ext2fs_parse_version_string): Check the passed in
1770 version string (instead of the hard-coded one).
1772 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1773 greater filesystem size, clamp it to prevent allocating a
1774 block or inode bitmap beyond the filesystem.
1776 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1777 overhead calculation was accidentally removed.
1779 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1781 * Release of E2fsprogs version 1.08
1783 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1785 * dblist.c (ext2fs_set_dir_block): New function which sets the
1786 block of a dblist entry, given the directory inode and
1789 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1791 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1792 inode bitmaps at staggered locations across the block
1793 groups, to avoid concentrating the bitmaps on a small
1794 number of disks when using striped RAID arrays.
1796 * initialize.c (ext2fs_initialize): By default, choose the maximum
1797 possible number of blocks per group (based on the size of
1798 the bitmaps in the blocksize).
1800 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1802 * initialize.c (ext2fs_initialize): Add support for
1803 EXT2_COMPAT_SPARSE_SUPER feature.
1805 * closefs.c (ext2fs_bg_has_super): New function to determine
1806 whether or a particular block group should have a
1807 superblock and block group descriptor. Used for the
1808 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1809 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1810 or not the superblock should be written out for the block
1813 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1814 for sparse duplicate superblocks.
1816 * version.c (ext2fs_get_library_version): New function which
1817 returns the library version.
1819 * version.c (ext2fs_parse_version_string): New function which
1820 parses a version string and returns a version number,
1821 so application programs can compare version numbers as
1824 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1826 * icount.c (ext2fs_create_icount): Change function so that it also
1827 takes a new argument which contains a "hint" icount
1828 structure. This "hint" icount allows the create function
1829 to set up the sorted list in advance. This reduces
1830 significantly the amount of data moving needed to insert
1831 these inodes into the list later.
1833 * icount.c (ext2fs_icount_validate): New function which validates
1834 that the icount structure's rep invariant.
1836 * icount.c (get_icount_el): Completely revamped implementation
1837 to subsume put_icount_el(). Put_icount_el() used to
1838 use an O(N) implementation to insert in the middle
1839 of the icount list. It now uses a O(ln N) to search
1840 for where the icount should be inserted, and then uses
1841 a memcpy to move the list down (instead of a for loop).
1843 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1844 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1845 to see if the inode is within bounds; if it isn't, return
1848 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1849 when a bad inode number is passed to test_generic_bitmap
1850 to be EXT2FS_TEST_ERROR instead of the wrong
1851 EXT2FS_UNMARK_ERROR.
1853 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1855 * Release of E2fsprogs version 1.07
1857 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1859 * Makefile.in (ELF_VERSION): Change version to be 2.2
1861 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1863 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1864 ext2fs_fast_test_block_bitmap_range().
1866 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1867 ext2fs_test_block_bitmap_range: New inline functions which
1868 test to see whether a contiguous range of blocks is
1871 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1873 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1874 use ext2fs_badblocks_* instead of badblocks_*
1876 * bb_compat.c: New file which translates between old badblocks_*()
1877 names to ext2fs_badblocks_*()
1879 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1880 link.c (since e2fsck doesn't use ext2fs_unlink()).
1882 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1883 bitmap resizing routine moved from bitmaps.c, since e2fsck
1884 doesn't need to use this function.
1886 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1887 since e2fsck only needs ext2fs_lookup.
1889 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1891 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1892 already set; this is needed so that programs like dump
1893 which use the inode scan functions will deal with
1894 filesystems that have bad blocks in the inode table.
1896 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1898 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1899 Moved to ext2fsP.h, since it doesn't need to be part of
1900 the public interface.
1902 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1904 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1906 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1907 directory block list abstraction. (Code moved from
1910 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1911 to inode.c (since no one else should be peeking inside it!)
1913 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1915 * openfs.c (ext2fs_open): Check the feature set in the ext2
1916 superblock, and refuse to open filesystems if they contain
1917 incompatible features. (Can be overriden with the
1920 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1922 * block.c (ext2fs_block_iterate2): Added new function
1923 ext2fs_block_iterate2 which changes the function
1924 signature of the callback function to include the
1925 referencing block and offset.
1927 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1928 ext2fs_inode_scan_goto_blockgroup which allows an
1929 application to jump to a particular block group while
1930 doing an inode scan.
1932 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1934 * dirblock.c: Include string.h, since we use memcpy().
1936 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1938 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1939 a long not an int; this doesn't matter on i386 machines,
1940 but it does on Alpha's.
1942 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1944 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1945 table pointer is NULL, then return an error indicating
1946 that the inode table is missing.
1947 (get_next_blockgroup, get_next_blocks,
1948 ext2fs_get_next_inode): Don't treat a missing inode table
1949 as permanent error. Return MISSING_INODE_TABLE, but as an
1950 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1952 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1953 ext2fs_write_inode_bitmap): If the inode or block bitmap
1954 block is zero, then don't write out the inode or block
1955 bitmap. The idea here is to avoid stomping on the
1957 (read_bitmaps): If the inode or block bitmap block is
1958 zero, then fill in that portion of the inode or block
1959 bitmap with all zeros.
1961 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1962 blocks in inode table when the inode table size is
1963 non-standard (and can therefore span blocks).
1965 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1967 * alloc.c (ext2fs_new_block): Fix fencepost error in
1968 ext2fs_new_block; make sure we don't try to allocate the
1969 first block beyond the end of the filesystem.
1971 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1973 * inode.c (check_for_inode_bad_blocks): New function called by
1974 get_next_blocks() to avoid reading in bad blocks marked in
1975 fs->badblocks. Inodes located in bad blocks are returned
1976 by ext2fs_get_next_inode() returns the error code
1977 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1979 * alloc_tables.c (ext2fs_allocate_tables): New function which
1980 performs the part of mke2fs's job of allocating the
1983 * test_io.c (test_close): IO manager which is used for testing
1986 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1988 * inode.c (ext2fs_get_next_inode): Separate out the function of
1989 setting up for a new block group to get_next_blockgroup().
1990 Separate out the function of reading in blocks of the
1991 inode table to get_next_blocks().
1993 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1995 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1996 blocks to the badblock list in sorted order. This allows
1997 badblocks_list_test to be coded using a binary search for
2000 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2002 * Release of E2fsprogs version 1.06
2004 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2006 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2007 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2010 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2011 set, then only write out the master superblock.
2013 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2015 * block.c (ext2fs_block_iterate): Fixed bug which caused
2016 block_iterate to fail to handle HURD created filesystems;
2017 it tested the inode translator field before the inode was
2020 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2022 * initialize.c (ext2fs_initialize): Make sure the description for
2023 the inode bitmap is set correctly.
2025 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

2029 * Release of E2fsprogs version 1.05
2031 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2033 * initialize.c: Override the kernel's idea of default
2034 checkinterval from 0 (never) to 180 days.

2043 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2044 for shortcut function fs->read_inode() and fs->write_inode().
2045 Added inode_cache to reduce CPU time spent in doing
2048 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
2051 * namei.c (ext2fs_follow_link): New function.
2052 (ext2fs_namei): Extended to have support for chasing
2053 symbolic links. ext2fs_namei() still returns an inode
2054 which is a symbolic link. Symbolic links are only chased
2055 while resolving the containing directory. To chase
2056 symbolic links of the final result, use
2057 ext2fs_follow_link().
2059 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2061 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2063 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2064 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

2068 * initialize.c (ext2fs_initialize): On systems where the byte
2069 order is not i386 compatible, set the swap_byte flag.
2071 * inode.c (inocpy_with_swap): Check to see if inode contains a
2072 fast symlink before swapping the inode block fields. This
2073 required adding a new argument to inocpy_with_swap to
2074 determine whether the mode field is in host order or not.
2076 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2078 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2079 the sparc, if EXT2_STD_BITOPS set, use the standard
2080 i386-compatible bitmask operations, instead on the
2081 non-standard native bitmask operators.
2083 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2085 * block.c (ext2fs_block_iterate): Cause block iterator to return
2086 the HURD translator block (along with everything else).
2087 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2088 iterator, then don't return any meta data blocks
2089 (including the HURD translator).
2091 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2093 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2095 * uuid.c: New file, containing UUID utility functions.
2097 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2105 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2107 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2108 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2109 that's a basic value that must be correct for the rest of
2110 the library to work.
2112 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2115 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2163 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2164 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2165 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2166 to avoid conflicts with with kernel include files. Also
2167 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2170 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2172 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
2174 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
2175 s_def_resuid and s_def_resgid for backwards compatibility.
2177 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

2190 * Makefile.in: Added support for BSD shared libraries.
2192 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2195 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2197 * unix_io.c (unix_open): Add a double check; if the passed in name
2198 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2200 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2202 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

2224 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2225 Move these functions to freefs.c.
2227 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2228 descriptors shadow memory to keep purify quiet. (This
2229 also has the nice benefit that the unused portion of the
2230 shadow descriptors are zeroed out.)
2232 * dirblock.c (ext2fs_write_dir_block): We need to use
2233 dirent->rec_len *before* it's byteswapped to find the
2234 location of the next directory structure!
2236 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2237 cause ext2fs_new_inode to loop infinitely if we're trying
2238 to allocate an inode in group #0 and there are no free
2239 inodes at all in the system.
2241 * closefs.c: #include <errno.h> if it exists.
2243 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2245 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2262 file containing functions for reading and writing
2263 directory blocks (byte swapping if necesssary)
2265 * block.c (block_iterate_ind, block_iterate_dind,
2266 block_iterate_tind): Byte swap the block addresses if
2267 EXT2_SWAP_BYTES is set (and swap them back before writing
2270 * inode.c (inocpy_with_swap): New function.
2271 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
2272 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2274 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2275 the superblock and group descriptors before writing it out.
2277 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2278 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2279 and group descriptors.
2281 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2282 to desp ext2 filesystem structures.
2284 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2285 supplied by Pete A. Zaitcev so that the C language
2286 versions of these functions are more portable. They will
2287 now work on both little and big endian systems, and the
2288 assumption that 32-bit integers are used is gone.
2290 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2291 doing byte swapping.
2293 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2294 byte swapping should take place.
2296 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

2307 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2308 if the magic number is correct, it will be allocated.
2310 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2312 * block.c (block_iterate_ind, block_iterate_dind,
2313 block_iterate_tind): Don't recompute block_nr each loop;
2314 just increment it! Factor check of BLOCK_FLAG_APPEND out
2315 of the loop. Factor mask of BLOCK_CHANGED into changed
2316 variable out of the loop. (block_iterate_ind, in
2317 particular, gets called a lot, so every little
2318 optimization helps.)
2320 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2322 * block.c (block_iterate_ind, block_iterate_dind,

2324 block_iterate_ind and company.
2326 * bitops.h (ext2fs_fast_mark_block_bitmap,
2327 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
2328 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2329 ext2fs_fast_test_inode_bitmap): Add fast version of these
2330 functions, which don't do range checking.
2332 * bitops.h (ext2fs_get_block_bitmap_start,
2333 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2334 ext2fs_get_inode_bitmap_end): Add new accessor functions
2335 which return the start and end points of the bitmaps.
2337 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2339 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2340 instead of llseek. The errno if the offset is too large
2341 and lseek is not supported should be EINVAL, not -EINVAL.
2343 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2345 * Makefile.in: Added support for ELF shared libraries.
2346 Fixed typos in the compilation rules.
2347 (distclean): Added Makefile.

2353 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2355 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
2357 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2359 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2361 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2362 the S_*, which are normally defined in <sys/stat.h>. This
2363 allows us to compile e2fsprogs on a non-Linux system,
2364 which may have a different value for S_IFDIR.
2366 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2368 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2369 this is a user-mode application!
2371 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2373 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2374 __linux__ so that non-linux systems won't see it.
2376 * alloc.c: Include <errno.h> if possible.
2377 * badblocks.c: Ditto.
2378 * bb_inode.c: Ditto.
2381 * expanddir.c: Ditto.
2382 * get_pathname.c: Ditto.
2383 * initialize.c: Ditto.
2390 * rw_bitmaps.c: Ditto.
2393 * Makefile.in: Rewritten to conform to GNU coding standards and
2394 support separate compilation directories.
2396 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2398 * initialize.c (ext2fs_initialize): Don't allow more than one
2399 bitmaps's worth of inodes in a group.
2401 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2403 * llseek.c (ext2_llseek): Added error checking to the llseek()
2404 compat code to protect against overflow. This only
2405 applies to 1.0 and early 1.1 kernels, which don't support
2406 the llseek() system call.
2408 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2410 * unix_io.c (unix_open): Initialize the read_error and write_error
2411 io_channel pointers to be null.
2413 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2414 found, clear it but don't try to update the filesystem
2415 accounting information, since that's hopeless anyway.
2417 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2418 bloblock_iterate_tind): Check to see if the indirect blocks are
2419 valid before trying to read them.

2422 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2424 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2425 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2426 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2427 illegal block or inode number is passed in, return instead
2428 of trying to test, set, or clear the bit.
2430 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2432 * Makefile: Added a dummy install target in case shared libraries

2446 the inode and block bitmaps.
2448 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2449 magic number for a block bitmap instead of an inode bitmap.

2455 badblocks_list_test, badblocks_list_iterate_begin,
2456 badblocks_list_iterate, badblocks_list_iterate_end): Add
2457 magic number checking for the badblocks_list and
2458 badblocks_iterate structures.
2460 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):

2484 ext2fs_allocate_block_bitmap):
2485 * bb_inode.c (ext2fs_update_bb_inode):
2486 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):

2498 structure magic numbers.
2500 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2501 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2502 someone uses the -b option to specify the use of the backup
2503 superblock --- this usually means that the main superblock is
2507 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2508 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2509 revision level to the superblock.
2511 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2518 * initialize.c: Completely revamped the inode and block bitmap
2519 structures, so that they can be better chance of being extensible
2520 in a shared library. They are now their own type, instead of
2521 being a char *. Also, the function signatures of
2522 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2523 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2524 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2525 changed to eliminate the ext2_filsys argument, since it is no

2530 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2531 system call if available.

2537 the creator operating system.
2539 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2541 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2542 the group descriptor statistics in addition to everything else.
2543 This relieves mke2fs of the responsibility of doing it.
2545 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2546 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2547 not the generic C function equivalents should be included or not.
2549 * openfs.c (ext2fs_open): If a superblock is specified, then use
2550 the backup group descriptors that go along with this superblock,
2551 instead of using the primary group descriptors. This allows
2552 e2fsck to recover filesystems where the primary group descriptors
