1 2002-07-29 Theodore Ts'o <tytso@mit.edu>
3 * link.c (ext2fs_link): When adding a new link to a directory,
6 2002-07-23 Theodore Ts'o <tytso@mit.edu>
8 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
9 calculations for names > 32 characters to be completely
10 bogus. Changed MD4 calculation to match what is currently
11 being used in the CVS gkernel tree.
13 2002-07-19 Theodore Ts'o <tytso@mit.edu>
15 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
16 superblock definition.
18 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
19 create a set of u32_list functions.
21 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
22 since that's required by the directory indexing code.
24 2002-07-14 Theodore Ts'o <tytso@mit.edu>
26 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
27 using a C++ reserved word.
29 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
30 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
31 old version of glibc (built against 2.2 headers) will
32 interact badly with the workaround to actually cause more
33 problems. I hate it when the glibc folks think they're
34 being smarter than the kernel....
36 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
38 * ext2_fs.h: Add superblock field for reserved group descriptors.
40 2002-06-28 Theodore Ts'o <tytso@mit.edu>
42 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
43 ext2fs_cpu_to_{l,b}e{32,16}
45 2002-06-27 Theodore Ts'o <tytso@mit.edu>
47 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
48 Add appropriate fallbacks in this case.
50 2002-06-26 Theodore Ts'o <tytso@mit.edu>
52 * dirhash.c (ext2fs_dirhash): Change function signature to support
53 a hash seed, and to return the minor hash (for 64-bit hash
54 support). Add support for the half MD4, half MD4 with
55 seed, and half MD4 with seed and 64 bits.
57 2002-06-15 Theodore Ts'o <tytso@mit.edu>
59 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
61 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
63 * ext2_fs.h: Add macros for maximum block/inode counts:
64 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
65 and EXT2_MAX_INODES_PER_GROUP.
67 * openfs.c (ext2fs_open): Check that the number of blocks in a group
68 is less than 2^16, otherwise we need an INCOMPAT flag (not
69 in existence yet, if ever) to open such a filesystem.
71 * initialize.c (ext2fs_initialize): Limit the number of blocks and
72 inodes in a group to less than 2^16.
74 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
76 * ext2_fs.h: Further minor cleanups of the header. Consolidate
77 some checks for __KERNEL__ into one place.
79 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
81 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
82 the EXT2_SB() macro instead. Remove kernel function
83 prototypes also. This matches the 2.5 kernel, and
84 is also cleaner for other reasons. Whitespace cleanup.
86 2002-05-21 Theodore Ts'o <tytso@mit.edu>
88 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
90 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
92 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
94 * initialize.c (ext2fs_initialize): Remove assumption that
95 blocksizes are always <= 4k.
97 2002-05-11 Theodore Ts'o <tytso@mit.edu>
99 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
100 silently if inode pointer is NULL (and ext2fs_bmap is
101 expected to read the inode itself).
103 2002-04-27 Theodore Ts'o <tytso@mit.edu>
105 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
106 file we are checking is a block device file before looking
107 at st_rdev, since it's not valid for normal files.
108 (is_swap_device): Move so that it is outside the
109 HAVE_MNTENT_H, so that it is always built.
111 2002-03-11 Theodore Tso <tytso@mit.edu>
113 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
114 functions which take an extra flags argument. The flag
115 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
116 field is byte swampped on big-endian machines, since in
117 the V2 structure, name_len is a char field which is
118 doesn't need to be byte swapped --- except if an
119 old-style kernel had byte-swapped the name_len field
120 as part of the V1 structure.
122 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
124 * dirhash.c (ext2fs_dirhash): New function which calculates the
125 hash for a filename in an indexed directory.
127 2002-03-08 Theodore Tso <tytso@mit.edu>
129 * Release of E2fsprogs 1.27
131 2002-03-07 Theodore Tso <tytso@mit.edu>
133 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
135 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
136 tst_byteswap.c: Fix gcc -Wall complaints
138 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
139 (From Philipp Thomas <pthomas@suse.de>)
141 2002-02-25 Theodore Tso <tytso@mit.edu>
143 * ext2_fs.h: Add structure definitions for the directory indexing
146 2002-02-23 Theodore Tso <tytso@mit.edu>
148 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
149 it doesn't break things on mis32, sparc32, and alpha
152 2002-02-21 Theodore Tso <tytso@mit.edu>
154 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
155 we were missing an fclose().
157 2002-02-20 Theodore Tso <tytso@mit.edu>
159 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
160 abstraction interface which exports an ext2 inode.
162 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
163 as a public interface. Change void * to const void * in
164 ext2fs_file_write's interface.
166 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
167 conditional; save a few bytes.
169 2002-02-12 Theodore Tso <tytso@mit.edu>
171 * Makefile.in (tst_badblocks): Add some extra .o files when
172 linking the debugging program tst_badblocks which are
173 needed if we aren't compiling with inline functions enable.
175 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
176 define away __inline__ since it may not be supported.
178 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
179 stripped down jbd_debug that doesn't use variadic
180 arguments. This will cause warnings under AIX, but things
183 2002-02-03 Theodore Tso <tytso@thunk.org>
185 * Release of E2fsprogs 1.26
187 2002-02-03 Theodore Tso <tytso@mit.edu>
189 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
190 so that the number of directories in use is adjusted
193 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
194 which optionally will modify the number of directories
197 2002-01-03 Theodore Tso <tytso@mit.edu>
199 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
200 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
201 which will return deleted directory entries.
202 ext2fs_dir_iterate2 takes a new callback function which
203 is identical with the one used by
204 ext2fs_dblist_dir_iterate(). If the directory entry is
205 deleted, the callback function will be called with the
206 entry paraemter set to DIRENT_DELETED_FILE.
208 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
209 ext2fs_block_alloc_stats): New functions which update
210 block/inode allocation statistics in the bitmaps, block
211 group descriptors, and superblock.
213 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
214 expanddir.c (expand_dir_proc), bb_inode.c
215 (clear_bad_block_proc, set_bad_block_proc,
216 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
217 Update to use new block/inode allocation statistics.
219 2001-12-24 Theodore Tso <tytso@mit.edu>
221 * ismounted.c (is_swap_device): New function used by
222 ext2fs_check_if_mounted and ext2fs_check_mount_point which
223 determines whether or not the specified device is a swap
224 device by using /proc/swaps. More bulletproofing for
225 idiotic/careless system administrators!
227 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
228 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
229 field to struct_ext2_filsys, umask. This field is
230 initialize to 022, and affects ext2fs_mkdir in the obvious
231 way. (In the future umask should also affect new file
232 creation routines, but the fileio functions don't
233 currently support this yes.)
235 * ismounted.c (check_mntent_file): Stat all of the entries in
236 /etc/mtab and/or /proc/mounts in order to catch dim-witted
237 system administrators who might have created alias
240 2001-12-23 Theodore Tso <tytso@mit.edu>
242 * Makefile.in, jfs_user.h: Move linux/jbd.h to
243 ext2fs/kernel-jbd.h, to avoid using the system header
244 file version of hbd.h when using diet glibc (since it
245 forcibly adds /usr/include to the beginning of the
246 include search path.)
248 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
249 include/linux directory.
251 2001-12-16 Theodore Tso <tytso@mit.edu>
253 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
254 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
255 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
257 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
260 2001-12-03 Theodore Tso <tytso@mit.edu>
262 * unix_io.c (unix_open): Make sure the ulimit workaround works
263 regardless of the version of glibc which is used to
266 2001-11-26 Theodore Tso <tytso@mit.edu>
268 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
269 trying to unset the filesize limit if at all possible,
270 if a block device is getting opened. (The filesize limit
271 shouldn't be applied against writes to a block device, but
272 starting in 2.4.10, the kernel is doing this.)
274 2001-11-05 Theodore Tso <tytso@mit.edu>
276 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
277 file on adding a journal to an already-mounted filesystem,
278 try to clear the ext2 file attributes on an already
279 existing .journal file so that we don't fail if on a
280 partially added journal to the filesystem.
282 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
283 which signals that a particular inode should not have the
284 last bits of data (the "tail") be merged with another
285 file. This is necessary to keep LILO happy.
287 2001-09-20 Theodore Tso <tytso@thunk.org>
289 * Release of E2fsprogs 1.25
291 2001-09-16 Theodore Tso <tytso@mit.edu>
293 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
294 which was breaking the build on the Hurd. (Addresses
297 2001-09-13 Theodore Ts'o <tytso@mit.edu>
299 * ismounted.c (check_mntent_file): We now validate the entry in
300 /etc/mtab to make sure the filesystem is really mounted,
301 since some broken distributions (read: Slackware) have
302 buggy boot scripts that don't initialize /etc/mtab before
303 checking non-root filesystems. (Slackware also doesn't
304 check the root filesystem separately, and reboot if the
305 root filesystem had changes applied to it, which is
306 dangerous and broken.)
308 2001-09-02 Theodore Tso <tytso@thunk.org>
310 * Release of E2fsprogs 1.24a
312 2001-08-30 Theodore Tso <tytso@thunk.org>
314 * Release of E2fsprogs 1.24
316 2001-08-30 Theodore Tso <tytso@valinux.com>
318 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
319 changes, since the ioctl number has been reused by another
322 2001-08-15 Theodore Tso <tytso@valinux.com>
324 * Release of E2fsprogs 1.23
326 2001-08-05 Theodore Tso <tytso@valinux.com>
328 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
329 version of the bitmap test routines to speed up these
330 routines. (At some point I may want to make these
331 routines use the find_first_bit functions, but that will
332 add a lot of complexity since it means that these
333 functions will have to break the bitmap abstraction
334 boundary. It's not clear it's worth it.)
336 * mkjournal.c (mkjournal_proc): Remember the last block allocated
337 to speed up ext2fs_new_block().
339 2001-07-29 Theodore Tso <tytso@valinux.com>
341 * finddev.c (scan_dir): Fix memory leak; we weren't calling
342 closedir() when exiting the function in all cases.
344 2001-07-27 Theodore Tso <tytso@valinux.com>
346 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
347 block usable in the journal for external journals to be 2
348 or 3, depending on the blocksize, so that the existing
349 kernel code does the right thing.
351 * getsize.c (ext2fs_get_device_size): Add support for the
352 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
353 from Ben LaHaise, but it's likely this interface won't
356 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
357 when writing the journal superblock, too. (Oops! Needed
358 to make 1k filesystems with external journal to work.)
360 2001-07-26 Theodore Tso <tytso@valinux.com>
362 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
363 to find the journal superblock if the blocksize is 1024.
365 2001-07-21 Theodore Tso <tytso@valinux.com>
367 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
369 2001-07-20 Theodore Tso <tytso@valinux.com>
371 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
372 attribute block, set the filesystem changed bit.
374 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
375 Comment out these functions since we're not using them.
377 2001-07-10 Theodore Tso <tytso@valinux.com>
379 * closefs.c (write_primary_superblock): After writing changes to
380 the primary superblock, update the original superblock
381 copy so we don't have to re-write those changes in the
383 (ext2fs_flush): Clear the superblock dirty flag after
384 we've flushed out changes to disk.
386 2001-07-07 Theodore Tso <tytso@valinux.com>
388 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
389 to avoid register conflicts when compiling in PIC mode.
391 2001-07-04 Theodore Tso <tytso@valinux.com>
393 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
394 Add new functions (C and in i386 assembler) which quickly
395 find bits set in a bitmask.
397 2001-06-23 Theodore Tso <tytso@valinux.com>
399 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
400 ext2_ext_attr.h and ext_attr.c for extended attributes
403 * Release of E2fsprogs 1.22
405 2001-06-22 Theodore Tso <tytso@valinux.com>
407 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
408 descriptor so that adding a journal to a mounted
409 filesystem doesn't die. (Fixes a bug accidentally
410 introduced in e2fsprogs 1.21.)
412 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
413 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
414 fchflags without defining UF_NODUMP. (Addresses Debian
417 * flushb.c: Use platform independent method of defining the
418 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
419 since on newer glibc's BLKFLSBUF is defined there.
421 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
422 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
423 to support byte swapping even if we don't support the
424 conversion functions. (Fixes Debian bug #101686).
426 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
427 since the byte-swapping code all assumes the
428 ext2_dir_entry structure. (It's a question of whether or
429 not name_len should be byte-swapped or not, and whether
430 it's a 16 bit or 8 bit field.)
432 2001-06-15 Theodore Tso <tytso@valinux.com>
434 * Release of E2fsprogs 1.21
436 2001-06-15 Theodore Tso <tytso@valinux.com>
438 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
439 file which is generated and is therefore found in the
440 build directory, not source directory.
442 * ismounted.c (check_mntent_file): Use a test file in / to check
443 to see if the root filesystem is mounted read-only. This
444 protects against the case where /etc might not be on /, as
445 well as the case where /etc/mtab doesn't exist. (Both are
446 should-never happen scenarios, but you never know...)
448 2001-06-14 Theodore Tso <tytso@valinux.com>
450 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
451 Remove unneeded #pragma argsused, since the arguments are
454 2001-06-13 Theodore Tso <tytso@valinux.com>
456 * ext2_types.h.in: If linux/types.h has been defined, then don't
457 try to redefine the typedefs.
459 * Makefile.in (HFILES): Add ext2_types.h to the list of files
460 which should be installed.
462 * ismounted.c (check_mntent_file): Work around GNU hurd brain
463 damage. Addresses Debian bug #100304.
465 * Makefile.in: Limit some .o files from being included into the
466 library if --disable-debugfs, --disable-swapfs,
467 --disable-imager, or --disable-resizer are used.
469 2001-06-12 Theodore Tso <tytso@valinux.com>
471 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
472 function, and use the ext2fs_badblocks_* functions
475 2001-06-11 Theodore Tso <tytso@valinux.com>
477 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
478 ext2fs_mark_generic_bitmap and
479 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
480 functions. (This saves space and doesn't significantly
481 change the speed of e2fsck on a P-III.)
483 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
484 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
485 include the byte-swapping logic if ENABLE_SWAPFS is turned
486 on or if we're on a big-endian machine.
488 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
489 set EXT2_FLAG_SWAP_BYTES, instead of using
492 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
493 autoconf to determine whether or not return
494 EXT2_FLAG_SWAP_BYTES.
496 2001-06-10 Theodore Tso <tytso@valinux.com>
498 * Makefile.in: Remove the dependence on the libe2p library.
500 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
501 with direct usage of the ioctl/fchflags so that we don't
502 have to depend on the libe2p library.
504 2001-06-08 Theodore Tso <tytso@valinux.com>
506 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
507 when trying to find a 32-bit wide type.
509 * icount.c (insert_icount_el): Fix the code used to estimate the
510 size of the new icount array to be more intelligent, to
511 avoid reallocating the array too many times. Thanks to
512 Enrique Perez-Terron for pointing this out.
514 2001-06-02 Theodore Tso <tytso@valinux.com>
516 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
517 for a symlink to determine whether it is a fast symlink.
519 2001-06-01 Theodore Tso <tytso@valinux.com>
521 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
522 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
524 2001-05-25 Theodore Tso <tytso@valinux.com>
526 * Release of E2fsprogs 1.20
528 2001-05-25 Theodore Tso <tytso@valinux.com>
530 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
531 some to clean up Andreas's patches. Use strncpy instead
532 of strcpy to save the root's mountpoint. Clean up #ifdef
533 structure. Remove uneeded variable in testing/debug driver.
535 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
537 * ismounted.c: Add check for root device which doesn't depend on
538 /etc/fstab or /proc/mounts to be correct. Don't call
539 endmntent() before we are done with mnt struct.
541 2001-05-23 Theodore Tso <tytso@valinux.com>
543 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
546 2001-05-21 Theodore Tso <tytso@valinux.com>
548 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
549 make room for pre-existing usage of
550 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
551 the same codepoint as EXT2_BTREE_FL.
553 2001-05-20 Theodore Tso <tytso@valinux.com>
555 * ext2fs.h: #include <> instead of "" for ext2fs and et header
556 files, since they will be installed in /usr/include
558 2001-05-14 Theodore Tso <tytso@valinux.com>
560 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
561 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

571 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
572 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
573 Adjust all files in this directroy to include this file.
575 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
578 2001-05-05 Theodore Tso <tytso@valinux.com>
580 * fileio.c (ext2fs_file_read): Factored out common code and
581 cleaned up function. Fixed a bug where if there was an
582 error reading from the disk, the number of bytes read
583 wasn't reliably set. (Fixes Debian bug #79163)
584 (ext2fs_file_write): Factored out common code and made
585 function more efficient; if writing a full block, don't
586 bother to do a read-modify-write cycle.
588 2001-05-04 Theodore Tso <tytso@valinux.com>
590 * dirblock.c (ext2fs_read_dir_block): Check for an directory
591 record length which isn't a multiple four, and treat that
592 as an invalid. Scan the directory and return an error
593 (EXT2_ET_DIR_CORRUPTED) if the directory records are
595 (ext2fs_write_dir_block): If while byte-swapping the
596 directory block, if there's an error, abort and return
597 EXT2_ET_DIR_CORRUPTED.
599 2001-05-02 Theodore Tso <tytso@valinux.com>
601 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
602 image_header field in the ext2_filsys structure
604 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
605 * inode.c (ext2fs_read_inode):
606 * rw_bitmaps.c (read_bitmaps):
607 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
609 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
610 sure the full bitmap is saved.
612 2001-05-01 Theodore Tso <tytso@valinux.com>
614 * e2image.h (struct ext2_image_hdr): Add space for the device name
617 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
618 make sure the rec_len is a multiple of 4, to prevent
619 bus-errors on architectures which care about mis-aligned
622 2001-04-25 Theodore Tso <tytso@valinux.com>
624 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
625 query the device sizes using the BLKGETSIZE ioctl.
627 2001-04-16 Theodore Tso <tytso@valinux.com>
629 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
630 before checking /etc/mtab. The EXT2_MF_READONLY flag is
631 now set from the /etc/mtab options field for all
632 filesystems, not just the root filesystem. Add debugging
633 code to make it easier to test ext2fs_check_if_mounted().
635 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
636 check; return an error if there's an attempt to create a
637 journal less than 1024 filesystem blocks.
639 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
640 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
642 2001-02-20 Theodore Tso <tytso@valinux.com>
644 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
647 * tst_byteswap.c: New function to test the byteswap functions.
648 Add to regression test suite.
650 2001-02-08 Theodore Tso <tytso@valinux.com>
652 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
654 2001-02-07 Theodore Tso <tytso@valinux.com>
656 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
657 of s_first for external devices to always be 1, since
658 jsb->s_first is always relative to the start of the
659 journal superblock. Use htonl(1) when setting s_nr_users.
661 2001-01-17 Theodore Ts'o <tytso@valinux.com>
663 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
664 device number of the filesystem (instead of the journal)
665 was being dropped into s_journal_dev.
667 2001-01-15 Theodore Ts'o <tytso@valinux.com>
669 * initialize.c (ext2fs_initialize): Add support for initializing
670 the ext2 superblock for external journal devices. This
671 basically means we don't bother to allocate any block
674 * openfs.c (ext2fs_open): Only open external journal devices if
675 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
676 ext2fs_open. When opening such devices, don't try to read
677 the block group descriptors, since they're not there.
679 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
681 * mkjournal.c: Export a new function,
682 ext2fs_create_journal_superblock(), which allocates and
683 returns a buffer containing a journal superblock. This is
684 needed by mke2fs to create an external journal. Rewrote
685 ext2fs_add_journal_device() so that it no longer creates
686 the external journal, but rather adds a filesystem to an
687 existing external journal. It handles all of the UUID
690 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
691 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
692 Changed function prototype for ext2fs_add_journal_device().
694 2001-01-14 Theodore Ts'o <tytso@valinux.com>
696 * closefs.c (ext2fs_flush): Don't write out anything beyond the
697 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
700 2001-01-12 Theodore Ts'o <tytso@valinux.com>
702 * imager.c: Fix gcc -Wall complaints and a series of bugs where
703 retval wasn't set correctly. (Thanks to Andreas Dilger
704 for pointing this out.)
706 2001-01-11 <tytso@snap.thunk.org>
708 * flushb.c (ext2fs_sync_device): New function which centralizes
709 all of the places which might try to use the BLKFLSBUF
710 or FDFLUSH ioctls (and usually failing to define them
711 since the system header files don't usually do this for
712 us, and we're trying to avoid usage of kernel include
715 2001-01-10 <tytso@snap.thunk.org>
717 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
718 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
719 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
720 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
721 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
722 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
723 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
724 ext2_ino_t, to protect applications that attempt to
725 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
726 changes ino_t(!?). So we use ext2_ino_t to avoid an
727 unexpected ABI change.
729 2001-01-05 <tytso@snap.thunk.org>
731 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
732 we may overrun allocated memory in case of a corrupted
733 filesystem (or an e2fsck test case :-) when byte-swapping
736 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
738 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
739 complaints including a missing return 0 at the end of
740 ext2fs_add_journal_device.
742 2001-01-03 <tytso@snap.thunk.org>
744 * Makefile.in: Link in libe2p when creating libext2fs as a shared
745 library, since mkjournal.c now references fsetflags().
747 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
748 Dilger's changes (with fixups) to allow on-line creation
751 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
752 EXT2_FLAG_SUPER_ONLY, which the close routines to only
753 update the superblock, and not the group descriptors.
755 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
757 * ismounted.c: add ext2fs_check_mount_point() function, which will
758 optionally return the mount point of a device if mounted
760 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
762 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
763 ext2fs_add_journal_inode()
765 2001-01-01 <tytso@snap.thunk.org>
767 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
768 source (but not binary) compatibility of some users of the
769 ext2 library. They should just simply do a global search
770 and replace of struct ext2fs_sb with struct
771 ext2_super_block, and use their own private copy of
772 ext2_fs.h if they aren't already.
774 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
775 Replace use of ext2fs_sb with ext2_super_block.
777 2000-12-31 <tytso@snap.thunk.org>
779 * ext2fs.h: Cleaned up header file by removing definitions of
780 feature flags that might not have been defined in older
781 ext2 header files. Now that we're using our own
782 include/linux/ext2fs.h header file, this can never happen.
784 * jfs_dat.h: Removed old header file which is no longer needed.
786 2000-12-13 Theodore Ts'o <tytso@valinux.com>
788 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
789 by Andreas Dilger to update the filesystem revision to
792 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
795 2000-12-09 <tytso@snap.thunk.org>
797 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
798 ext2fs_add_journal_device): Add a new argument to the APIs
799 of these function, which is a flags word. This is used to
800 allow the creation of a V1 superblock for those folks who
801 are using ext3 0.3b in production. Note, the user-land
802 interface for getting at this flag won't be documented, as
803 the V1 superblock is deprecated.
805 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
806 which creates a V2 superblock instead of a V1 superblock.
808 2000-11-21 <tytso@snap.thunk.org>
810 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
811 out by Andreas Dilger.
813 2000-11-05 <tytso@snap.thunk.org>
815 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
816 ext2_fs.h, Makefile.in: New file that has routines that
817 save ext2fs metadata to a file.
819 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
821 * e2image.h: New file which defines the file format for the ext2
822 image file. (Saved copy of ext2 metadata to a file as a
823 saving throw against worst-case damage.)
825 2000-11-01 <tytso@snap.thunk.org>
827 * inode.c (ext2fs_flush_icache): Add new function
828 ext2fs_flush_icache() which flushes the internal inode
829 cache. Applications which modify the inode table blocks
830 directly must call this function.
832 2000-10-26 <tytso@snap.thunk.org>
834 * mkjournal.c: Add #include of netinet/in.h, since Solaris
835 requires it for ntohl().
837 * ext2_io.h (io_channel_write_byte): Add new interface to allow
838 callers to write specific byte ranges. This is an
839 optional interface, which not all IO channels may
842 * unix_io.c (unix_write_byte):
843 * test_io.c (test_write_byte): Add implementation of the
846 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
847 function which writes the primary superblock. If the IO
848 channel supports writing raw bytes directly, only fields
849 which were modified are written to the disk. This makes
850 it safe(r) to use utilities like tune2fs on a mounted
853 * freefs.c (ext2fs_free): Free the original superblock if it is
856 * openfs.c (ext2fs_open): Store a copy of the original superblock
859 * ext2fs.h: Add a field to store the original superblock in the
860 ext2 context structure.
862 2000-10-24 <tytso@snap.thunk.org>
864 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
865 don't need to use llseek).
867 2000-10-24 <tytso@valinux.com>
869 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
870 creating an ext3 journal on a filesystem.
872 2000-08-21 <tytso@valinux.com>
874 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
876 2000-08-22 <tytso@valinux.com>
878 * unix_io.c: Make massive changes to support a multiple block
879 writethrough cacheing.
881 * ext2_io.h: Added flags field to the io_channel structure.
883 2000-08-19 <tytso@valinux.com>
885 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
886 provides the function ext2fs_find_block_device(). This
887 function returns the pathname to a block device, given its
890 2000-07-13 <tytso@valinux.com>
892 * Release of E2fsprogs 1.19
894 2000-07-07 Theodore Ts'o <tytso@valinux.com>
896 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
897 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
898 list of filesystem flags supported by the library.
900 2000-07-04 Theodore Ts'o <tytso@valinux.com>
902 * ext2fs.h: Update to include latest journalling additions to the
905 * dll/jump.funcs: Add new jumptable entries for
906 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
907 ext2fs_badblocks_equal.
909 * tst_badblocks.c: Update test program to test
910 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
912 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
913 writes out bad blocks list to a file.
915 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
916 changes the callback function to take two additional
917 arguments; a private blind pointer supplied by the caller,
918 and pointer to a char * containing a pointer to the
921 * badblocks.c (ext2fs_badblocks_equal): Add new function which
922 returns true if two badblocks list are equal.
924 * Makefile.in: Remove explicit link of -lc in the shared library.
925 (It shouldn't be necessary, and is harmful in some cases).
927 2000-06-10 Theodore Ts'o <tytso@valinux.com>
929 * getsize.c (main): Add debugging code under #ifdef DEBUG
931 2000-05-27 Theodore Ts'o <tytso@valinux.com>
933 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
934 earlier, so that if there's an error reading it, we can
935 more cleanly back out of the operation.
937 2000-05-25 <tytso@snap.thunk.org>
939 * getsize.c (ext2fs_get_device_size): Use open64() instead of
940 open() if it exists. Under linux, manually define the
941 ioctl for BLKGETSIZE if it isn't already defined and it's
944 * unix_io.c (unix_open): Use open64() instead of open() if it
947 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
948 available (and prototypes are defined) use it in
949 preference to llseek.
951 * Makefile: Add hack dependency rule so that parallel makes work
954 2000-05-18 Theodore Ts'o <tytso@valinux.com>
956 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
958 2000-04-03 Theodore Ts'o <tytso@valinux.com>
960 * block.c: Readibility tweak in conditionals involving
963 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
964 how to define __s64 and __u64. Turn off "compression is
965 experimental" warning if the cpp macro
966 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
968 2000-02-11 <tytso@snap.thunk.org>
970 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
971 Conditionally include Compression as a supported type if
972 ENABLE_COMPRESSION (via --enable-compression) is turned on.
974 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
976 2000-02-08 <tytso@snap.thunk.org>
978 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
979 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
980 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
981 Change to return the previous state of the bit that is
982 being marked or unmarked. For speed optimization.
984 2000-02-02 Theodore Ts'o <tytso@valinux.com>
986 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
988 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
989 needed any more; we know it will always be i_generation.
990 Add support for swapping the high bits of the uid and gid.
992 1999-11-19 <tytso@valinux.com>
994 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
995 counts if the link was successful. Patch suggested by
998 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
999 the source directory.
1001 1999-11-10 <tytso@valinux.com>
1003 * Release of E2fsprogs 1.18
1005 1999-11-08 <tytso@valinux.com>
1007 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1008 since ext2fs_badblocks_list_free was moved to freefs.c.
1010 * tst_badblocks.c: Use the newer badblocks API names. Add
1011 duplicate blocks to the test inputs to test dealing with
1012 adding blocks which are already in the badblocks list.
1014 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1015 of the list, use a shortcut O(1) operations instead of an
1016 O(n) operation. (Idea suggested by David Beattie.)
1018 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1019 of badblocks_list_free(), to save a procedure call.
1021 1999-10-26 <tytso@valinux.com>
1023 * Release of E2fsprogs 1.17
1025 1999-10-26 <tytso@valinux.com>
1027 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1028 seem to handle ~0UL the same way as they used to.
1030 1999-10-25 <tytso@valinux.com>
1032 * nt_io.c (_OpenNtName): Open the device using
1033 FILE_SYNCHRONOUS_IO_NONALERT instead of
1034 FILE_SYNCHRONOUS_IO_ALERT
1035 (nt_open): At the end of the device open routine, unlock
1036 the drive but do not dismount it.
1038 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
1041 1999-10-22 <tytso@valinux.com>
1043 * Release of E2fsprogs 1.16
1045 1999-10-22 <tytso@valinux.com>
1047 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1049 * link.c (ext2fs_link): This call now uses the low three bits of
1050 the flags parameter to pass the directory filetype
1051 information; it will set the directory entry FILETYPE
1052 information if the filesystem supports it.
1054 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1055 option is set, then create the '.' and '..' entries with
1056 the filetype set to EXT2_FT_DIR.
1058 1999-09-24 <tytso@valinux.com>
1060 * nt_io.c: New file which supports I/O under Windows NT.
1062 1999-09-07 <tytso@valinux.com>
1064 * ext2fs.h: Add new fields for journalling and define new
1065 feature bits used by newer filesystems: IMAGIC_INODES,
1066 HAS_JOURNAL, RECOVER.
1068 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1069 we update the inode block count and size files so that the
1070 block count field is updated correctly when we create an
1073 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1075 * Release of E2fsprogs 1.15
1077 1999-06-23 <tytso@valinux.com>
1079 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1080 kernels that use i_generation instead of i_version. Patch
1081 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1083 1999-06-21 <tytso@valinux.com>
1085 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1086 directory entry before calling the callback function.
1087 This should prevent some core dumps of insufficiently
1088 paranoid callback functions.
1090 1999-05-29 <tytso@rsts-11.mit.edu>
1092 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1094 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1095 that we don't handle writing yet (we do). Fixed bug where
1096 we weren't allocating a big enough buffer for ext2_bmap.
1098 1999-05-03 <tytso@rsts-11.mit.edu>
1100 * openfs.c (ext2fs_open): Check to make sure that the number of
1101 blocks per group is not zero --- if so, it must be a bad
1104 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1106 * Release of E2fsprogs 1.14
1108 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1110 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1111 the inode number is zero; if it's zero, return
1112 EXT2_ET_BAD_INODE_NUM.
1114 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1116 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1117 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1120 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1122 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1123 non-Linux case to use EINVAL by default, unless it isn't
1124 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1127 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1129 * Release of E2fsprogs 1.13
1131 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1133 * Makefile.in: Updated dependencies.
1135 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1137 * initialize.c (ext2fs_initialize): Make sure that we allocate
1138 enough inodes so that we can make a valid filesystem.
1140 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1142 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1144 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1145 function declaration.
1147 * dblist.c (make_dblist): Add safety check in case the dblist
1148 pointer passed in is null (in which case, assign it to
1149 fs->dblist). Fixed some signed/unsigned warnings.
1151 * bmap.c: Make addr_per_block be of type blk_t to avoid
1152 signed/unsigned warnings.
1154 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1155 function declaration.
1157 * get_pathname.c (get_pathname_proc): Use return value from
1158 ext2fs_get_mem, instead of checking if &gp->name is
1161 * dir_iterate.c (ext2fs_process_dir_block):
1162 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1163 from the function declaration.
1165 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1166 return the error directly instead of jumping to the
1167 cleanup routine, since we don't need to do any cleanup.
1169 * alloc_table.c (ext2fs_allocate_group_table): Make this
1170 function take a dgrp_t for its group argument.
1172 * ext2fs.h: Make dgrp_t an __u32 type, and make
1173 fs->desc_group_count be of type dgrp_t.
1175 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1177 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1178 than 10 blocks when we need to expand the size of the
1181 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1183 * Release of E2fsprogs 1.12
1185 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1187 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1188 appropriate for all of the block group copies, so that
1189 it's clear where the beginning of the filesystem is on the
1190 disk. (For when the partition table gets scrod.)
1192 * ext2fs.h: Change the name of the feature from
1193 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1194 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1196 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1198 * inode.c (get_next_blockgroup): Fix bug where if
1199 get_next_blockgroup() is called early because of a missing
1200 inode table in a block group, the current_inode counter
1201 wasn't incremented correctly.
1203 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1205 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1206 against a completely trashed bad block inode.
1208 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1210 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1211 the stride length hits a bad value, we retry the block
1212 allocation starting at the beginning of the block group.
1214 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1215 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1216 e2_blkcnt_t to avoid collision with LFS API.
1218 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1220 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1221 way that avoids overflows on disk sizes greater than 4GB.
1223 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1225 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1226 return type for comparison functions for qsort.
1228 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1231 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1233 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1236 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1237 evade a potential problem with glibc's header files trying
1238 to spike out linux/types.h.
1240 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1241 include the old size of the memory, which is needed for
1242 some braindamaged memory allocation systems that don't
1245 * badblocks.c (ext2fs_badblocks_list_add):
1246 bb_inode.c (clear_bad_block_proc):

1250 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1251 pass the old size of the memory to be resized to
1252 ext2fs_resize_mem().
1254 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1256 * Makefile.in: Change to use new installation directory variables
1257 convention. Fix uninstall rules to take $(DESTDIR) into
1260 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1262 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1263 with 32 bit longs, then we need to manually define __s64
1264 and __u64, since the current kernel header files don't
1265 define these if __STRICT_ANSI__ is defined. This is a
1266 problem if we are compiling with full GCC warnings, since
1267 we do need 64 bit support.
1269 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1270 since we're not using ext2fs_move_blocks() and there
1271 is some question as to its usefulness in its current
1274 * bmap.c (block_bmap): Remove unused function.
1276 * bmove.c (process_block): Fix -Wall warning.
1278 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1280 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1281 contain the offset into the inode.i_blocks array when
1282 ref_block is zero. Since we haven't done a formal
1283 release of e2fsprogs since block_iterate2 was first
1284 introduced, I removed block_iterate2, and renamed
1285 block_iterate3 to be block_iterate2.
1287 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1288 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1289 use of block_iterate and block_iterate2 to
1290 block_iterate2 with the new prototype for the
1291 interator function. (using blkcnt_t forr blockcount)
1293 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1295 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1296 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1297 conditional defines of new features COMPAT_DIR_PREALLOC,
1298 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1299 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1300 the library to declare that we support COMPAT_DIR_PREALLOC,
1301 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1303 * fileio.c: Rename function ext2fs_file_llseek to be
1304 ext2fs_file_lseek, which is more accurate.
1306 * block.c: Add new function ext2fs_block_iterate3 which calls
1307 the iterator function with the blockcount argument of
1308 type blkcnt_t. This version of the function is
1309 allowed to handle large files; the other fucntions are
1312 * ext2fs.h: Add new type blkcnt_t
1314 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1316 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1317 field wasn't getting correctly incremented for sparse
1318 files when the indirect or doubly-indirect block
1319 specified in the inode was zero.
1321 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1323 * unlink.c (unlink_proc):
1324 * lookup.c (lookup_proc):
1325 * link.c (link_proc):
1326 * get_pathname.c (get_pathname_proc):
1327 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1328 from dirent->name_len, so it can be used for other
1331 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1332 and indicate that we have support for this incompatible
1335 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1337 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
1339 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1341 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
1342 number of directories when the block group information is
1345 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1347 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1348 inode table is missing so that we catch the case where the
1349 first block group is missing.
1351 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1354 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1356 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1358 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1360 * test_io.c (test_flush): Add a debugging printf when the flush
1363 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1364 read in, return right away.
1366 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1368 * bitops.h: Don't try to do i386 inline asm functions if the
1371 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1372 instead of linux/types.h, and e2_bitops.h instead of
1375 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1378 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1380 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1381 so that we don't need to call get_next_blockgroup() the
1382 first time around. Saves a bit of time, and prevents us
1383 from needing to assign -1 to current_group (which is an
1386 * icount.c (insert_icount_el): Cast the estimated number of inodes
1387 from a float to an ino_t.
1389 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
1390 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1391 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

1399 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1400 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
1401 defined, then assume all of the
1402 ext2-specific header files are in a flat directory.
1404 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1405 all assignments from void * to be compatible with C++.
1407 Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1409 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
1410 make sure the contents of the disk are flushed to disk.
1412 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1414 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
1415 avoid C++ namespace clash.
1417 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
1418 avoid C++ namespace clash.
1420 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
1421 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
1422 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
1423 unlink.c: Change private to be priv_data (to avoid C++
1426 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1428 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1429 paranoid about validating the directory counts from the
1430 block group information.
1432 * all files: Don't include stdlib.h anymore; include it in
1433 ext2_fs.h, since that file requires stdlib.h
1435 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1437 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1438 bitmap is loaded, and return an error if it is not.
1439 (expand_dir_proc): Only use ext2fs_write_dir_block when
1440 writing a directory block, not when writing out a fresh
1443 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1467 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1469 * [all files, basically]: Added definition of ext2fs_get_mem,
1470 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1471 changed all library routines to use these wrapper functions.

1491 * fileio.c: New file which implements simple file reading and
1494 * alloc.c (ext2fs_alloc_block): New function which allocates a
1495 block, zeros it, and updates the filesystem accounting

1514 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1516 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
1518 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1522 * icount.c (ext2fs_icount_validate):
1523 * bmove.c (process_block): Fix lint error in type for fprintf().
1525 Mon Sep 15 11:45:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1527 * inode.c (ext2fs_check_directory): Add support for the callback
1528 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
1530 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1532 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
1533 padding of the bitmap to be all one's.
1535 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
1537 * llseek.c: Added missing semicolon to glibc fixup declaration of
1540 * bmove.c: Add #include of errno.h
1542 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1544 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
1545 added a new field to the io_channel (app_data).
1547 * io.h: Add a new element to the io_channel structure, app_data.
1549 * initialize.c, openfs.c: Set io->app_data to point at the
1552 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1554 * io.h: Change the prototype of ext2fs_llseek() to use int's
1555 instead of unsigned int's.
1557 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1558 to make life easer for GNU Libc 2.
1560 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1561 filesystem has its bitmaps stored as 32-bit words with bit
1562 0 as the LSB of each word. Thus a bitmap with only bit 0
1563 set would be, as a string of bytes, 00 00 00 01 00 ... To
1564 cope with this, we byte-reverse each word of a bitmap if
1565 we have a big-endian filesystem, that is, if we are *not*
1566 byte-swapping other word-sized numbers.
1568 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1586 and size_t where appropriate.
1588 * closefs.c (ext2fs_flush): Use dgrp_t instead of int where
1591 * openfs.c (ext2fs_open):
1592 * check_desc.c (ext2fs_check_desc): Use blk_t instead of int where

1635 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1637 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1638 is zero, then return EXT2_IO_LLSEEK_FAILED.
1640 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1642 * Release of E2fsprogs 1.11
1644 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1646 * dblist.c (ext2fs_dblist_count): Added new function which returns
1647 the number of directory blocks in dblist.
1649 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1651 * unix_io.c (unix_flush): Make the io_channel flush function do a
1652 fsync to flush the kernel buffers to disk.
1654 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1656 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1657 current inode number wasn't being set by the
1658 goto_blockgroup function.
1660 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1662 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1663 of blocks which need to be moved, and moves those blocks
1664 to another location in the filesystem.
1666 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1667 bitmap, make sure all of the new parts of the bitmap are
1670 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1672 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1673 wasn't being returned to the caller.
1675 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1676 ext2fs_allocate_group_table() which sets the group tables
1677 for a particular block group. The relevant code was
1678 factored out of ext2fs_allocate_tables().
1680 * dblist.c (make_dblist): Adjust the initial size of the directory
1681 block list to be a bit more realistic (ten plus twice the
1682 number of directories in the filesystem).
1684 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1686 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1687 ext2fs_badblocks_list_test would test the list (and exceed
1688 array boundaries) if there were no bad blocks on the bad
1689 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1691 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1693 * Release of E2fsprogs version 1.10
1695 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1697 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1698 inode and block bitmaps based on the RAID 0 stride
1699 parameter (which is passed by mke2fs).
1701 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1702 mke2fs to communicate the stride length to
1703 ext2fs_allocate_tables()
1705 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1707 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1708 systems. (We can't assume that the new filesystem types
1711 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1713 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1714 allocate the inode and block bitmaps inside block group at
1717 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1719 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1720 filesystem has no free blocks, ext2fs_new_block would loop
1723 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1725 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only

1742 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1744 (unix_close, test_close): Decrement the refcount and only
1745 close the io_channel if the refcount goes to 0.
1747 * io.h: Add refcount to the io_channel structure. Add new macro
1748 interface io_channel_bumpcount() to bump the refcount.
1750 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1752 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1753 cache in the filesystem handle, instead of the inode cache
1754 in a static variable.
1756 * freefs.c: Added static function to free the inode cache (called by
1759 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1761 * ext2fs.h: Added pointer to the inode_cache structure.
1763 * block.c (block_iterate_ind, block_iterate_dind,
1764 block_iterate_tind): If there are holes in the indirect,
1765 doubly indirect, or triply indirect blocks, increment the
1766 block count field automatically.
1768 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1770 * Release of E2fsprogs version 1.09
1772 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1774 * version.c (ext2fs_parse_version_string): Check the passed in
1775 version string (instead of the hard-coded one).
1777 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1778 greater filesystem size, clamp it to prevent allocating a
1779 block or inode bitmap beyond the filesystem.
1781 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1782 overhead calculation was accidentally removed.
1784 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1786 * Release of E2fsprogs version 1.08
1788 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1790 * dblist.c (ext2fs_set_dir_block): New function which sets the
1791 block of a dblist entry, given the directory inode and
1794 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1796 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1797 inode bitmaps at staggered locations across the block
1798 groups, to avoid concentrating the bitmaps on a small
1799 number of disks when using striped RAID arrays.
1801 * initialize.c (ext2fs_initialize): By default, choose the maximum
1802 possible number of blocks per group (based on the size of
1803 the bitmaps in the blocksize).
1805 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1807 * initialize.c (ext2fs_initialize): Add support for
1808 EXT2_COMPAT_SPARSE_SUPER feature.
1810 * closefs.c (ext2fs_bg_has_super): New function to determine
1811 whether or a particular block group should have a
1812 superblock and block group descriptor. Used for the
1813 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1814 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1815 or not the superblock should be written out for the block
1818 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1819 for sparse duplicate superblocks.
1821 * version.c (ext2fs_get_library_version): New function which
1822 returns the library version.
1824 * version.c (ext2fs_parse_version_string): New function which
1825 parses a version string and returns a version number,
1826 so application programs can compare version numbers as
1829 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1831 * icount.c (ext2fs_create_icount): Change function so that it also
1832 takes a new argument which contains a "hint" icount
1833 structure. This "hint" icount allows the create function
1834 to set up the sorted list in advance. This reduces
1835 significantly the amount of data moving needed to insert
1836 these inodes into the list later.
1838 * icount.c (ext2fs_icount_validate): New function which validates
1839 that the icount structure's rep invariant.
1841 * icount.c (get_icount_el): Completely revamped implementation
1842 to subsume put_icount_el(). Put_icount_el() used to
1843 use an O(N) implementation to insert in the middle
1844 of the icount list. It now uses a O(ln N) to search
1845 for where the icount should be inserted, and then uses
1846 a memcpy to move the list down (instead of a for loop).
1848 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1849 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1850 to see if the inode is within bounds; if it isn't, return
1853 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1854 when a bad inode number is passed to test_generic_bitmap
1855 to be EXT2FS_TEST_ERROR instead of the wrong
1856 EXT2FS_UNMARK_ERROR.
1858 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1860 * Release of E2fsprogs version 1.07
1862 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1864 * Makefile.in (ELF_VERSION): Change version to be 2.2
1866 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1868 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1869 ext2fs_fast_test_block_bitmap_range().
1871 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1872 ext2fs_test_block_bitmap_range: New inline functions which
1873 test to see whether a contiguous range of blocks is
1876 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1878 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1879 use ext2fs_badblocks_* instead of badblocks_*
1881 * bb_compat.c: New file which translates between old badblocks_*()
1882 names to ext2fs_badblocks_*()
1884 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1885 link.c (since e2fsck doesn't use ext2fs_unlink()).
1887 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1888 bitmap resizing routine moved from bitmaps.c, since e2fsck
1889 doesn't need to use this function.
1891 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1892 since e2fsck only needs ext2fs_lookup.
1894 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1896 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1897 already set; this is needed so that programs like dump
1898 which use the inode scan functions will deal with
1899 filesystems that have bad blocks in the inode table.
1901 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1903 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1904 Moved to ext2fsP.h, since it doesn't need to be part of
1905 the public interface.
1907 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1909 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1911 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1912 directory block list abstraction. (Code moved from
1915 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1916 to inode.c (since no one else should be peeking inside it!)
1918 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1920 * openfs.c (ext2fs_open): Check the feature set in the ext2
1921 superblock, and refuse to open filesystems if they contain
1922 incompatible features. (Can be overriden with the
1925 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1927 * block.c (ext2fs_block_iterate2): Added new function
1928 ext2fs_block_iterate2 which changes the function
1929 signature of the callback function to include the
1930 referencing block and offset.
1932 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1933 ext2fs_inode_scan_goto_blockgroup which allows an
1934 application to jump to a particular block group while
1935 doing an inode scan.
1937 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1939 * dirblock.c: Include string.h, since we use memcpy().
1941 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1943 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1944 a long not an int; this doesn't matter on i386 machines,
1945 but it does on Alpha's.
1947 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1949 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1950 table pointer is NULL, then return an error indicating
1951 that the inode table is missing.
1952 (get_next_blockgroup, get_next_blocks,
1953 ext2fs_get_next_inode): Don't treat a missing inode table
1954 as permanent error. Return MISSING_INODE_TABLE, but as an
1955 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1957 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1958 ext2fs_write_inode_bitmap): If the inode or block bitmap
1959 block is zero, then don't write out the inode or block
1960 bitmap. The idea here is to avoid stomping on the
1962 (read_bitmaps): If the inode or block bitmap block is
1963 zero, then fill in that portion of the inode or block
1964 bitmap with all zeros.
1966 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1967 blocks in inode table when the inode table size is
1968 non-standard (and can therefore span blocks).
1970 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1972 * alloc.c (ext2fs_new_block): Fix fencepost error in
1973 ext2fs_new_block; make sure we don't try to allocate the
1974 first block beyond the end of the filesystem.
1976 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1978 * inode.c (check_for_inode_bad_blocks): New function called by
1979 get_next_blocks() to avoid reading in bad blocks marked in
1980 fs->badblocks. Inodes located in bad blocks are returned
1981 by ext2fs_get_next_inode() returns the error code
1982 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1984 * alloc_tables.c (ext2fs_allocate_tables): New function which
1985 performs the part of mke2fs's job of allocating the
1988 * test_io.c (test_close): IO manager which is used for testing
1991 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1993 * inode.c (ext2fs_get_next_inode): Separate out the function of
1994 setting up for a new block group to get_next_blockgroup().
1995 Separate out the function of reading in blocks of the
1996 inode table to get_next_blocks().
1998 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
2000 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2001 blocks to the badblock list in sorted order. This allows
2002 badblocks_list_test to be coded using a binary search for
2005 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2007 * Release of E2fsprogs version 1.06
2009 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2011 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2012 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2015 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2016 set, then only write out the master superblock.
2018 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2020 * block.c (ext2fs_block_iterate): Fixed bug which caused
2021 block_iterate to fail to handle HURD created filesystems;
2022 it tested the inode translator field before the inode was
2025 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2027 * initialize.c (ext2fs_initialize): Make sure the description for
2028 the inode bitmap is set correctly.
2030 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

2036 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2038 * initialize.c: Override the kernel's idea of default
2039 checkinterval from 0 (never) to 180 days.

2048 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2049 for shortcut function fs->read_inode() and fs->write_inode().
2050 Added inode_cache to reduce CPU time spent in doing
2053 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
2056 * namei.c (ext2fs_follow_link): New function.
2057 (ext2fs_namei): Extended to have support for chasing
2058 symbolic links. ext2fs_namei() still returns an inode
2059 which is a symbolic link. Symbolic links are only chased
2060 while resolving the containing directory. To chase
2061 symbolic links of the final result, use
2062 ext2fs_follow_link().
2064 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2066 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2068 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2069 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

2073 * initialize.c (ext2fs_initialize): On systems where the byte
2074 order is not i386 compatible, set the swap_byte flag.
2076 * inode.c (inocpy_with_swap): Check to see if inode contains a
2077 fast symlink before swapping the inode block fields. This
2078 required adding a new argument to inocpy_with_swap to
2079 determine whether the mode field is in host order or not.
2081 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2083 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2084 the sparc, if EXT2_STD_BITOPS set, use the standard
2085 i386-compatible bitmask operations, instead on the
2086 non-standard native bitmask operators.
2088 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2090 * block.c (ext2fs_block_iterate): Cause block iterator to return
2091 the HURD translator block (along with everything else).
2092 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2093 iterator, then don't return any meta data blocks
2094 (including the HURD translator).
2096 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2098 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2100 * uuid.c: New file, containing UUID utility functions.
2102 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2104 * ext2fs.h: Add a definition of the "real" ext2 superblock.

2110 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2112 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2113 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2114 that's a basic value that must be correct for the rest of
2115 the library to work.
2117 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2120 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2168 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2169 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2170 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2171 to avoid conflicts with with kernel include files. Also
2172 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2175 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2177 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
2179 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
2180 s_def_resuid and s_def_resgid for backwards compatibility.
2182 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

2195 * Makefile.in: Added support for BSD shared libraries.
2197 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2200 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2202 * unix_io.c (unix_open): Add a double check; if the passed in name
2203 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2205 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2207 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

2229 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2230 Move these functions to freefs.c.
2232 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2233 descriptors shadow memory to keep purify quiet. (This
2234 also has the nice benefit that the unused portion of the
2235 shadow descriptors are zeroed out.)
2237 * dirblock.c (ext2fs_write_dir_block): We need to use
2238 dirent->rec_len *before* it's byteswapped to find the
2239 location of the next directory structure!
2241 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2242 cause ext2fs_new_inode to loop infinitely if we're trying
2243 to allocate an inode in group #0 and there are no free
2244 inodes at all in the system.
2246 * closefs.c: #include <errno.h> if it exists.
2248 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2250 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2267 file containing functions for reading and writing
2268 directory blocks (byte swapping if necesssary)
2270 * block.c (block_iterate_ind, block_iterate_dind,
2271 block_iterate_tind): Byte swap the block addresses if
2272 EXT2_SWAP_BYTES is set (and swap them back before writing
2275 * inode.c (inocpy_with_swap): New function.
2276 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
2277 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2279 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2280 the superblock and group descriptors before writing it out.
2282 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2283 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2284 and group descriptors.
2286 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2287 to desp ext2 filesystem structures.
2289 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2290 supplied by Pete A. Zaitcev so that the C language
2291 versions of these functions are more portable. They will
2292 now work on both little and big endian systems, and the
2293 assumption that 32-bit integers are used is gone.
2295 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2296 doing byte swapping.
2298 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2299 byte swapping should take place.
2301 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

2310 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
2312 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2313 if the magic number is correct, it will be allocated.
2315 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2317 * block.c (block_iterate_ind, block_iterate_dind,
2318 block_iterate_tind): Don't recompute block_nr each loop;
2319 just increment it! Factor check of BLOCK_FLAG_APPEND out
2320 of the loop. Factor mask of BLOCK_CHANGED into changed
2321 variable out of the loop. (block_iterate_ind, in
2322 particular, gets called a lot, so every little
2323 optimization helps.)
2325 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2327 * block.c (block_iterate_ind, block_iterate_dind,

2329 block_iterate_ind and company.
2331 * bitops.h (ext2fs_fast_mark_block_bitmap,
2332 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
2333 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2334 ext2fs_fast_test_inode_bitmap): Add fast version of these
2335 functions, which don't do range checking.
2337 * bitops.h (ext2fs_get_block_bitmap_start,
2338 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2339 ext2fs_get_inode_bitmap_end): Add new accessor functions
2340 which return the start and end points of the bitmaps.
2342 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2344 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2345 instead of llseek. The errno if the offset is too large
2346 and lseek is not supported should be EINVAL, not -EINVAL.
2348 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2350 * Makefile.in: Added support for ELF shared libraries.
2351 Fixed typos in the compilation rules.
2352 (distclean): Added Makefile.
2354 * llseek.c (llseek): New function, if llseek() does not exist in the

2358 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2360 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
2362 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2364 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2366 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2367 the S_*, which are normally defined in <sys/stat.h>. This
2368 allows us to compile e2fsprogs on a non-Linux system,
2369 which may have a different value for S_IFDIR.
2371 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2373 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2374 this is a user-mode application!
2376 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2378 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2379 __linux__ so that non-linux systems won't see it.
2381 * alloc.c: Include <errno.h> if possible.
2382 * badblocks.c: Ditto.
2383 * bb_inode.c: Ditto.
2386 * expanddir.c: Ditto.
2387 * get_pathname.c: Ditto.
2388 * initialize.c: Ditto.
2395 * rw_bitmaps.c: Ditto.
2398 * Makefile.in: Rewritten to conform to GNU coding standards and
2399 support separate compilation directories.
2401 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2403 * initialize.c (ext2fs_initialize): Don't allow more than one
2404 bitmaps's worth of inodes in a group.
2406 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2408 * llseek.c (ext2_llseek): Added error checking to the llseek()
2409 compat code to protect against overflow. This only
2410 applies to 1.0 and early 1.1 kernels, which don't support
2411 the llseek() system call.
2413 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2415 * unix_io.c (unix_open): Initialize the read_error and write_error
2416 io_channel pointers to be null.
2418 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2419 found, clear it but don't try to update the filesystem
2420 accounting information, since that's hopeless anyway.
2422 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2423 bloblock_iterate_tind): Check to see if the indirect blocks are
2424 valid before trying to read them.

2427 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2429 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2430 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2431 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2432 illegal block or inode number is passed in, return instead
2433 of trying to test, set, or clear the bit.
2435 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2437 * Makefile: Added a dummy install target in case shared libraries
2440 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2442 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

2448 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
2449 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,

2451 the inode and block bitmaps.
2453 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2454 magic number for a block bitmap instead of an inode bitmap.

2460 badblocks_list_test, badblocks_list_iterate_begin,
2461 badblocks_list_iterate, badblocks_list_iterate_end): Add
2462 magic number checking for the badblocks_list and
2463 badblocks_iterate structures.
2465 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
2466 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
2467 unix_write_blk, unix_flush): Add magic number checking
2468 both for io_channel structure and unix_private_data
2471 * openfs.c (ext2fs_open): Add check for io_manager structure's
2474 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2475 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2476 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2477 * read_bb.c (ext2fs_read_bb_inode):
2478 * read_bb_file.c (ext2fs_read_bb_FILE):
2479 * newdir.c (ext2fs_new_dir_block):

2489 ext2fs_allocate_block_bitmap):
2490 * bb_inode.c (ext2fs_update_bb_inode):
2491 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
2492 * check_desc.c (ext2fs_check_desc):
2493 * closefs.c (ext2fs_close, ext2fs_flush):
2494 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2499 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2500 openfs.c into its own file.
2502 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2503 structure magic numbers.
2505 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2506 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2507 someone uses the -b option to specify the use of the backup
2508 superblock --- this usually means that the main superblock is
2512 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2513 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2514 revision level to the superblock.
2516 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2523 * initialize.c: Completely revamped the inode and block bitmap
2524 structures, so that they can be better chance of being extensible
2525 in a shared library. They are now their own type, instead of
2526 being a char *. Also, the function signatures of
2527 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2528 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2529 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2530 changed to eliminate the ext2_filsys argument, since it is no
2533 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2535 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2536 system call if available.
2538 * llseek.c: new file. This is the stub calling the llseek system
2539 call which allows supports for 2GB+ file systems.
2541 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2542 the creator operating system.
2544 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2546 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2547 the group descriptor statistics in addition to everything else.
2548 This relieves mke2fs of the responsibility of doing it.
2550 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2551 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2552 not the generic C function equivalents should be included or not.
2554 * openfs.c (ext2fs_open): If a superblock is specified, then use
2555 the backup group descriptors that go along with this superblock,
2556 instead of using the primary group descriptors. This allows
2557 e2fsck to recover filesystems where the primary group descriptors
