1 2001-08-31 Theodore Tso <tytso@thunk.org>
3 * Release of E2fsprogs 1.28
5 2002-08-31 Theodore Ts'o <tytso@valinux.com>
7 * dblist.c (ext2fs_dblist_sort): New function which allows the
8 caller to pass in a special sort comparison function.
10 2002-08-20 Theodore Ts'o <tytso@mit.edu>
12 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
13 failed to accurately characterize non-standard slow
14 symlinks. (Which don't appear in practice on real-life
15 systems, fortunately.)
17 2002-08-17 Theodore Ts'o <tytso@mit.edu>
19 * Makefile.in: Remove inode_io.o from the standard object files,
20 and only build it if debugfs is enabled (it requires
21 fileio.o, which is only built if --disable-debugfs isn't
22 specified to configure).
24 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
25 incompatible way so that it is no longer
26 endian-dependent. Add the TEA hash. Allow the seed
27 parameter to be optional.
29 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
30 These features are all now in the HALF_MD4 hash. Add
31 definition for EXT2_HASH_TEA.
33 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
34 a pointer instead of an array.
36 2002-08-16 Theodore Ts'o <tytso@mit.edu>
38 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
40 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
41 the number of data blocks used by an inode exclusive of
44 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
45 adjusts the reference count in an extended attribute block.
47 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
48 correctly deal with extended attribute blocks in symbolic
51 2002-08-13 <tytso@snap.thunk.org>
53 * Makefile.in: Move dupfs.o and test_io.o from the
54 needed-by-debugfs object list to the needed-by-resizer
55 object list. Fixes compile problem if the system is built
56 with only --disable-debugfs.
58 2002-07-29 Theodore Ts'o <tytso@mit.edu>
60 * link.c (ext2fs_link): When adding a new link to a directory,
63 2002-07-23 Theodore Ts'o <tytso@mit.edu>
65 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
66 calculations for names > 32 characters to be completely
67 bogus. Changed MD4 calculation to match what is currently
68 being used in the CVS gkernel tree.
70 2002-07-19 Theodore Ts'o <tytso@mit.edu>
72 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
73 superblock definition.
75 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
76 create a set of u32_list functions.
78 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
79 since that's required by the directory indexing code.
81 2002-07-14 Theodore Ts'o <tytso@mit.edu>
83 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
84 using a C++ reserved word.
86 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
87 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
88 old version of glibc (built against 2.2 headers) will
89 interact badly with the workaround to actually cause more
90 problems. I hate it when the glibc folks think they're
91 being smarter than the kernel....
93 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
95 * ext2_fs.h: Add superblock field for reserved group descriptors.
97 2002-06-28 Theodore Ts'o <tytso@mit.edu>
99 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
100 ext2fs_cpu_to_{l,b}e{32,16}
102 2002-06-27 Theodore Ts'o <tytso@mit.edu>
104 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
105 Add appropriate fallbacks in this case.
107 2002-06-26 Theodore Ts'o <tytso@mit.edu>
109 * dirhash.c (ext2fs_dirhash): Change function signature to support
110 a hash seed, and to return the minor hash (for 64-bit hash
111 support). Add support for the half MD4, half MD4 with
112 seed, and half MD4 with seed and 64 bits.
114 2002-06-15 Theodore Ts'o <tytso@mit.edu>
116 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
118 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
120 * ext2_fs.h: Add macros for maximum block/inode counts:
121 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
122 and EXT2_MAX_INODES_PER_GROUP.
124 * openfs.c (ext2fs_open): Check that the number of blocks in a group
125 is less than 2^16, otherwise we need an INCOMPAT flag (not
126 in existence yet, if ever) to open such a filesystem.
128 * initialize.c (ext2fs_initialize): Limit the number of blocks and
129 inodes in a group to less than 2^16.
131 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
133 * ext2_fs.h: Further minor cleanups of the header. Consolidate
134 some checks for __KERNEL__ into one place.
136 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
138 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
139 the EXT2_SB() macro instead. Remove kernel function
140 prototypes also. This matches the 2.5 kernel, and
141 is also cleaner for other reasons. Whitespace cleanup.
143 2002-05-21 Theodore Ts'o <tytso@mit.edu>
145 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
147 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
149 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
151 * initialize.c (ext2fs_initialize): Remove assumption that
152 blocksizes are always <= 4k.
154 2002-05-11 Theodore Ts'o <tytso@mit.edu>
156 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
157 silently if inode pointer is NULL (and ext2fs_bmap is
158 expected to read the inode itself).
160 2002-04-27 Theodore Ts'o <tytso@mit.edu>
162 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
163 file we are checking is a block device file before looking
164 at st_rdev, since it's not valid for normal files.
165 (is_swap_device): Move so that it is outside the
166 HAVE_MNTENT_H, so that it is always built.
168 2002-03-11 Theodore Tso <tytso@mit.edu>
170 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
171 functions which take an extra flags argument. The flag
172 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
173 field is byte swampped on big-endian machines, since in
174 the V2 structure, name_len is a char field which is
175 doesn't need to be byte swapped --- except if an
176 old-style kernel had byte-swapped the name_len field
177 as part of the V1 structure.
179 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
181 * dirhash.c (ext2fs_dirhash): New function which calculates the
182 hash for a filename in an indexed directory.
184 2002-03-08 Theodore Tso <tytso@mit.edu>
186 * Release of E2fsprogs 1.27
188 2002-03-07 Theodore Tso <tytso@mit.edu>
190 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
192 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
193 tst_byteswap.c: Fix gcc -Wall complaints
195 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
196 (From Philipp Thomas <pthomas@suse.de>)
198 2002-02-25 Theodore Tso <tytso@mit.edu>
200 * ext2_fs.h: Add structure definitions for the directory indexing
203 2002-02-23 Theodore Tso <tytso@mit.edu>
205 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
206 it doesn't break things on mis32, sparc32, and alpha
209 2002-02-21 Theodore Tso <tytso@mit.edu>
211 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
212 we were missing an fclose().
214 2002-02-20 Theodore Tso <tytso@mit.edu>
216 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
217 abstraction interface which exports an ext2 inode.
219 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
220 as a public interface. Change void * to const void * in
221 ext2fs_file_write's interface.
223 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
224 conditional; save a few bytes.
226 2002-02-12 Theodore Tso <tytso@mit.edu>
228 * Makefile.in (tst_badblocks): Add some extra .o files when
229 linking the debugging program tst_badblocks which are
230 needed if we aren't compiling with inline functions enable.
232 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
233 define away __inline__ since it may not be supported.
235 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
236 stripped down jbd_debug that doesn't use variadic
237 arguments. This will cause warnings under AIX, but things
240 2002-02-03 Theodore Tso <tytso@thunk.org>
242 * Release of E2fsprogs 1.26
244 2002-02-03 Theodore Tso <tytso@mit.edu>
246 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
247 so that the number of directories in use is adjusted
250 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
251 which optionally will modify the number of directories
254 2002-01-03 Theodore Tso <tytso@mit.edu>
256 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
257 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
258 which will return deleted directory entries.
259 ext2fs_dir_iterate2 takes a new callback function which
260 is identical with the one used by
261 ext2fs_dblist_dir_iterate(). If the directory entry is
262 deleted, the callback function will be called with the
263 entry paraemter set to DIRENT_DELETED_FILE.
265 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
266 ext2fs_block_alloc_stats): New functions which update
267 block/inode allocation statistics in the bitmaps, block
268 group descriptors, and superblock.
270 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
271 expanddir.c (expand_dir_proc), bb_inode.c
272 (clear_bad_block_proc, set_bad_block_proc,
273 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
274 Update to use new block/inode allocation statistics.
276 2001-12-24 Theodore Tso <tytso@mit.edu>
278 * ismounted.c (is_swap_device): New function used by
279 ext2fs_check_if_mounted and ext2fs_check_mount_point which
280 determines whether or not the specified device is a swap
281 device by using /proc/swaps. More bulletproofing for
282 idiotic/careless system administrators!
284 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
285 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
286 field to struct_ext2_filsys, umask. This field is
287 initialize to 022, and affects ext2fs_mkdir in the obvious
288 way. (In the future umask should also affect new file
289 creation routines, but the fileio functions don't
290 currently support this yes.)
292 * ismounted.c (check_mntent_file): Stat all of the entries in
293 /etc/mtab and/or /proc/mounts in order to catch dim-witted
294 system administrators who might have created alias
297 2001-12-23 Theodore Tso <tytso@mit.edu>
299 * Makefile.in, jfs_user.h: Move linux/jbd.h to
300 ext2fs/kernel-jbd.h, to avoid using the system header
301 file version of hbd.h when using diet glibc (since it
302 forcibly adds /usr/include to the beginning of the
303 include search path.)
305 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
306 include/linux directory.
308 2001-12-16 Theodore Tso <tytso@mit.edu>
310 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
311 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
312 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
314 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
317 2001-12-03 Theodore Tso <tytso@mit.edu>
319 * unix_io.c (unix_open): Make sure the ulimit workaround works
320 regardless of the version of glibc which is used to
323 2001-11-26 Theodore Tso <tytso@mit.edu>
325 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
326 trying to unset the filesize limit if at all possible,
327 if a block device is getting opened. (The filesize limit
328 shouldn't be applied against writes to a block device, but
329 starting in 2.4.10, the kernel is doing this.)
331 2001-11-05 Theodore Tso <tytso@mit.edu>
333 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
334 file on adding a journal to an already-mounted filesystem,
335 try to clear the ext2 file attributes on an already
336 existing .journal file so that we don't fail if on a
337 partially added journal to the filesystem.
339 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
340 which signals that a particular inode should not have the
341 last bits of data (the "tail") be merged with another
342 file. This is necessary to keep LILO happy.
344 2001-09-20 Theodore Tso <tytso@thunk.org>
346 * Release of E2fsprogs 1.25
348 2001-09-16 Theodore Tso <tytso@mit.edu>
350 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
351 which was breaking the build on the Hurd. (Addresses
354 2001-09-13 Theodore Ts'o <tytso@mit.edu>
356 * ismounted.c (check_mntent_file): We now validate the entry in
357 /etc/mtab to make sure the filesystem is really mounted,
358 since some broken distributions (read: Slackware) have
359 buggy boot scripts that don't initialize /etc/mtab before
360 checking non-root filesystems. (Slackware also doesn't
361 check the root filesystem separately, and reboot if the
362 root filesystem had changes applied to it, which is
363 dangerous and broken.)
365 2001-09-02 Theodore Tso <tytso@thunk.org>
367 * Release of E2fsprogs 1.24a
369 2001-08-30 Theodore Tso <tytso@thunk.org>
371 * Release of E2fsprogs 1.24
373 2001-08-30 Theodore Tso <tytso@valinux.com>
375 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
376 changes, since the ioctl number has been reused by another
379 2001-08-15 Theodore Tso <tytso@valinux.com>
381 * Release of E2fsprogs 1.23
383 2001-08-05 Theodore Tso <tytso@valinux.com>
385 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
386 version of the bitmap test routines to speed up these
387 routines. (At some point I may want to make these
388 routines use the find_first_bit functions, but that will
389 add a lot of complexity since it means that these
390 functions will have to break the bitmap abstraction
391 boundary. It's not clear it's worth it.)
393 * mkjournal.c (mkjournal_proc): Remember the last block allocated
394 to speed up ext2fs_new_block().
396 2001-07-29 Theodore Tso <tytso@valinux.com>
398 * finddev.c (scan_dir): Fix memory leak; we weren't calling
399 closedir() when exiting the function in all cases.
401 2001-07-27 Theodore Tso <tytso@valinux.com>
403 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
404 block usable in the journal for external journals to be 2
405 or 3, depending on the blocksize, so that the existing
406 kernel code does the right thing.
408 * getsize.c (ext2fs_get_device_size): Add support for the
409 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
410 from Ben LaHaise, but it's likely this interface won't
413 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
414 when writing the journal superblock, too. (Oops! Needed
415 to make 1k filesystems with external journal to work.)
417 2001-07-26 Theodore Tso <tytso@valinux.com>
419 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
420 to find the journal superblock if the blocksize is 1024.
422 2001-07-21 Theodore Tso <tytso@valinux.com>
424 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
426 2001-07-20 Theodore Tso <tytso@valinux.com>
428 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
429 attribute block, set the filesystem changed bit.
431 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
432 Comment out these functions since we're not using them.
434 2001-07-10 Theodore Tso <tytso@valinux.com>
436 * closefs.c (write_primary_superblock): After writing changes to
437 the primary superblock, update the original superblock
438 copy so we don't have to re-write those changes in the
440 (ext2fs_flush): Clear the superblock dirty flag after
441 we've flushed out changes to disk.
443 2001-07-07 Theodore Tso <tytso@valinux.com>
445 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
446 to avoid register conflicts when compiling in PIC mode.
448 2001-07-04 Theodore Tso <tytso@valinux.com>
450 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
451 Add new functions (C and in i386 assembler) which quickly
452 find bits set in a bitmask.
454 2001-06-23 Theodore Tso <tytso@valinux.com>
456 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
457 ext2_ext_attr.h and ext_attr.c for extended attributes
460 * Release of E2fsprogs 1.22
462 2001-06-22 Theodore Tso <tytso@valinux.com>
464 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
465 descriptor so that adding a journal to a mounted
466 filesystem doesn't die. (Fixes a bug accidentally
467 introduced in e2fsprogs 1.21.)
469 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
470 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
471 fchflags without defining UF_NODUMP. (Addresses Debian
474 * flushb.c: Use platform independent method of defining the
475 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
476 since on newer glibc's BLKFLSBUF is defined there.
478 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
479 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
480 to support byte swapping even if we don't support the
481 conversion functions. (Fixes Debian bug #101686).
483 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
484 since the byte-swapping code all assumes the
485 ext2_dir_entry structure. (It's a question of whether or
486 not name_len should be byte-swapped or not, and whether
487 it's a 16 bit or 8 bit field.)
489 2001-06-15 Theodore Tso <tytso@valinux.com>
491 * Release of E2fsprogs 1.21
493 2001-06-15 Theodore Tso <tytso@valinux.com>
495 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
496 file which is generated and is therefore found in the
497 build directory, not source directory.
499 * ismounted.c (check_mntent_file): Use a test file in / to check
500 to see if the root filesystem is mounted read-only. This
501 protects against the case where /etc might not be on /, as
502 well as the case where /etc/mtab doesn't exist. (Both are
503 should-never happen scenarios, but you never know...)
505 2001-06-14 Theodore Tso <tytso@valinux.com>
507 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
508 Remove unneeded #pragma argsused, since the arguments are
511 2001-06-13 Theodore Tso <tytso@valinux.com>
513 * ext2_types.h.in: If linux/types.h has been defined, then don't
514 try to redefine the typedefs.
516 * Makefile.in (HFILES): Add ext2_types.h to the list of files
517 which should be installed.
519 * ismounted.c (check_mntent_file): Work around GNU hurd brain
520 damage. Addresses Debian bug #100304.
522 * Makefile.in: Limit some .o files from being included into the
523 library if --disable-debugfs, --disable-swapfs,
524 --disable-imager, or --disable-resizer are used.
526 2001-06-12 Theodore Tso <tytso@valinux.com>
528 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
529 function, and use the ext2fs_badblocks_* functions
532 2001-06-11 Theodore Tso <tytso@valinux.com>
534 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
535 ext2fs_mark_generic_bitmap and
536 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
537 functions. (This saves space and doesn't significantly
538 change the speed of e2fsck on a P-III.)
540 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
541 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
542 include the byte-swapping logic if ENABLE_SWAPFS is turned
543 on or if we're on a big-endian machine.
545 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
546 set EXT2_FLAG_SWAP_BYTES, instead of using
549 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
550 autoconf to determine whether or not return
551 EXT2_FLAG_SWAP_BYTES.
553 2001-06-10 Theodore Tso <tytso@valinux.com>
555 * Makefile.in: Remove the dependence on the libe2p library.
557 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
558 with direct usage of the ioctl/fchflags so that we don't
559 have to depend on the libe2p library.
561 2001-06-08 Theodore Tso <tytso@valinux.com>
563 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
564 when trying to find a 32-bit wide type.
566 * icount.c (insert_icount_el): Fix the code used to estimate the
567 size of the new icount array to be more intelligent, to
568 avoid reallocating the array too many times. Thanks to
569 Enrique Perez-Terron for pointing this out.
571 2001-06-02 Theodore Tso <tytso@valinux.com>
573 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
574 for a symlink to determine whether it is a fast symlink.
576 2001-06-01 Theodore Tso <tytso@valinux.com>
578 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
579 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
581 2001-05-25 Theodore Tso <tytso@valinux.com>
583 * Release of E2fsprogs 1.20
585 2001-05-25 Theodore Tso <tytso@valinux.com>
587 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
588 some to clean up Andreas's patches. Use strncpy instead
589 of strcpy to save the root's mountpoint. Clean up #ifdef
590 structure. Remove uneeded variable in testing/debug driver.
592 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
594 * ismounted.c: Add check for root device which doesn't depend on
595 /etc/fstab or /proc/mounts to be correct. Don't call
596 endmntent() before we are done with mnt struct.
598 2001-05-23 Theodore Tso <tytso@valinux.com>
600 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
603 2001-05-21 Theodore Tso <tytso@valinux.com>
605 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
606 make room for pre-existing usage of
607 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
608 the same codepoint as EXT2_BTREE_FL.
610 2001-05-20 Theodore Tso <tytso@valinux.com>
612 * ext2fs.h: #include <> instead of "" for ext2fs and et header
613 files, since they will be installed in /usr/include
615 2001-05-14 Theodore Tso <tytso@valinux.com>
617 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
618 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
619 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
620 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,
621 expanddir.c, ext2_fs.h, fileio.c, finddev.c, flushb.c,
622 freefs.c, get_pathname.c, getsize.c, icount.c, imager.c,

625 newdir.c, nt_io.c, openfs.c, read_bb.c, read_bb_file.c,
626 rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c,
627 tst_badblocks.c, tst_byteswap.c, tst_getsize.c,
628 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
629 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
630 Adjust all files in this directroy to include this file.
632 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
635 2001-05-05 Theodore Tso <tytso@valinux.com>
637 * fileio.c (ext2fs_file_read): Factored out common code and
638 cleaned up function. Fixed a bug where if there was an
639 error reading from the disk, the number of bytes read
640 wasn't reliably set. (Fixes Debian bug #79163)
641 (ext2fs_file_write): Factored out common code and made
642 function more efficient; if writing a full block, don't
643 bother to do a read-modify-write cycle.
645 2001-05-04 Theodore Tso <tytso@valinux.com>
647 * dirblock.c (ext2fs_read_dir_block): Check for an directory
648 record length which isn't a multiple four, and treat that
649 as an invalid. Scan the directory and return an error
650 (EXT2_ET_DIR_CORRUPTED) if the directory records are
652 (ext2fs_write_dir_block): If while byte-swapping the
653 directory block, if there's an error, abort and return
654 EXT2_ET_DIR_CORRUPTED.
656 2001-05-02 Theodore Tso <tytso@valinux.com>
658 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
659 image_header field in the ext2_filsys structure
661 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
662 * inode.c (ext2fs_read_inode):
663 * rw_bitmaps.c (read_bitmaps):
664 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
666 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
667 sure the full bitmap is saved.
669 2001-05-01 Theodore Tso <tytso@valinux.com>
671 * e2image.h (struct ext2_image_hdr): Add space for the device name
674 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
675 make sure the rec_len is a multiple of 4, to prevent
676 bus-errors on architectures which care about mis-aligned
679 2001-04-25 Theodore Tso <tytso@valinux.com>
681 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
682 query the device sizes using the BLKGETSIZE ioctl.
684 2001-04-16 Theodore Tso <tytso@valinux.com>
686 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
687 before checking /etc/mtab. The EXT2_MF_READONLY flag is
688 now set from the /etc/mtab options field for all
689 filesystems, not just the root filesystem. Add debugging
690 code to make it easier to test ext2fs_check_if_mounted().
692 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
693 check; return an error if there's an attempt to create a
694 journal less than 1024 filesystem blocks.
696 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
697 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
699 2001-02-20 Theodore Tso <tytso@valinux.com>
701 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
704 * tst_byteswap.c: New function to test the byteswap functions.
705 Add to regression test suite.
707 2001-02-08 Theodore Tso <tytso@valinux.com>
709 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
711 2001-02-07 Theodore Tso <tytso@valinux.com>
713 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
714 of s_first for external devices to always be 1, since
715 jsb->s_first is always relative to the start of the
716 journal superblock. Use htonl(1) when setting s_nr_users.
718 2001-01-17 Theodore Ts'o <tytso@valinux.com>
720 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
721 device number of the filesystem (instead of the journal)
722 was being dropped into s_journal_dev.
724 2001-01-15 Theodore Ts'o <tytso@valinux.com>
726 * initialize.c (ext2fs_initialize): Add support for initializing
727 the ext2 superblock for external journal devices. This
728 basically means we don't bother to allocate any block
731 * openfs.c (ext2fs_open): Only open external journal devices if
732 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
733 ext2fs_open. When opening such devices, don't try to read
734 the block group descriptors, since they're not there.
736 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
738 * mkjournal.c: Export a new function,
739 ext2fs_create_journal_superblock(), which allocates and
740 returns a buffer containing a journal superblock. This is
741 needed by mke2fs to create an external journal. Rewrote
742 ext2fs_add_journal_device() so that it no longer creates
743 the external journal, but rather adds a filesystem to an
744 existing external journal. It handles all of the UUID
747 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
748 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
749 Changed function prototype for ext2fs_add_journal_device().
751 2001-01-14 Theodore Ts'o <tytso@valinux.com>
753 * closefs.c (ext2fs_flush): Don't write out anything beyond the
754 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
757 2001-01-12 Theodore Ts'o <tytso@valinux.com>
759 * imager.c: Fix gcc -Wall complaints and a series of bugs where
760 retval wasn't set correctly. (Thanks to Andreas Dilger
761 for pointing this out.)
763 2001-01-11 <tytso@snap.thunk.org>
765 * flushb.c (ext2fs_sync_device): New function which centralizes
766 all of the places which might try to use the BLKFLSBUF
767 or FDFLUSH ioctls (and usually failing to define them
768 since the system header files don't usually do this for
769 us, and we're trying to avoid usage of kernel include
772 2001-01-10 <tytso@snap.thunk.org>
774 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
775 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
776 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
777 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
778 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
779 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
780 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
781 ext2_ino_t, to protect applications that attempt to
782 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
783 changes ino_t(!?). So we use ext2_ino_t to avoid an
784 unexpected ABI change.
786 2001-01-05 <tytso@snap.thunk.org>
788 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
789 we may overrun allocated memory in case of a corrupted
790 filesystem (or an e2fsck test case :-) when byte-swapping
793 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
795 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
796 complaints including a missing return 0 at the end of
797 ext2fs_add_journal_device.
799 2001-01-03 <tytso@snap.thunk.org>
801 * Makefile.in: Link in libe2p when creating libext2fs as a shared
802 library, since mkjournal.c now references fsetflags().
804 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
805 Dilger's changes (with fixups) to allow on-line creation
808 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
809 EXT2_FLAG_SUPER_ONLY, which the close routines to only
810 update the superblock, and not the group descriptors.
812 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
814 * ismounted.c: add ext2fs_check_mount_point() function, which will
815 optionally return the mount point of a device if mounted
817 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
819 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
820 ext2fs_add_journal_inode()
822 2001-01-01 <tytso@snap.thunk.org>
824 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
825 source (but not binary) compatibility of some users of the
826 ext2 library. They should just simply do a global search
827 and replace of struct ext2fs_sb with struct
828 ext2_super_block, and use their own private copy of
829 ext2_fs.h if they aren't already.
831 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
832 Replace use of ext2fs_sb with ext2_super_block.
834 2000-12-31 <tytso@snap.thunk.org>
836 * ext2fs.h: Cleaned up header file by removing definitions of
837 feature flags that might not have been defined in older
838 ext2 header files. Now that we're using our own
839 include/linux/ext2fs.h header file, this can never happen.
841 * jfs_dat.h: Removed old header file which is no longer needed.
843 2000-12-13 Theodore Ts'o <tytso@valinux.com>
845 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
846 by Andreas Dilger to update the filesystem revision to
849 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
852 2000-12-09 <tytso@snap.thunk.org>
854 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
855 ext2fs_add_journal_device): Add a new argument to the APIs
856 of these function, which is a flags word. This is used to
857 allow the creation of a V1 superblock for those folks who
858 are using ext3 0.3b in production. Note, the user-land
859 interface for getting at this flag won't be documented, as
860 the V1 superblock is deprecated.
862 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
863 which creates a V2 superblock instead of a V1 superblock.
865 2000-11-21 <tytso@snap.thunk.org>
867 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
868 out by Andreas Dilger.
870 2000-11-05 <tytso@snap.thunk.org>
872 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
873 ext2_fs.h, Makefile.in: New file that has routines that
874 save ext2fs metadata to a file.
876 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
878 * e2image.h: New file which defines the file format for the ext2
879 image file. (Saved copy of ext2 metadata to a file as a
880 saving throw against worst-case damage.)
882 2000-11-01 <tytso@snap.thunk.org>
884 * inode.c (ext2fs_flush_icache): Add new function
885 ext2fs_flush_icache() which flushes the internal inode
886 cache. Applications which modify the inode table blocks
887 directly must call this function.
889 2000-10-26 <tytso@snap.thunk.org>
891 * mkjournal.c: Add #include of netinet/in.h, since Solaris
892 requires it for ntohl().
894 * ext2_io.h (io_channel_write_byte): Add new interface to allow
895 callers to write specific byte ranges. This is an
896 optional interface, which not all IO channels may
899 * unix_io.c (unix_write_byte):
900 * test_io.c (test_write_byte): Add implementation of the
903 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
904 function which writes the primary superblock. If the IO
905 channel supports writing raw bytes directly, only fields
906 which were modified are written to the disk. This makes
907 it safe(r) to use utilities like tune2fs on a mounted
910 * freefs.c (ext2fs_free): Free the original superblock if it is
913 * openfs.c (ext2fs_open): Store a copy of the original superblock
916 * ext2fs.h: Add a field to store the original superblock in the
917 ext2 context structure.
919 2000-10-24 <tytso@snap.thunk.org>
921 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
922 don't need to use llseek).
924 2000-10-24 <tytso@valinux.com>
926 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
927 creating an ext3 journal on a filesystem.
929 2000-08-21 <tytso@valinux.com>
931 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
933 2000-08-22 <tytso@valinux.com>
935 * unix_io.c: Make massive changes to support a multiple block
936 writethrough cacheing.
938 * ext2_io.h: Added flags field to the io_channel structure.
940 2000-08-19 <tytso@valinux.com>
942 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
943 provides the function ext2fs_find_block_device(). This
944 function returns the pathname to a block device, given its
947 2000-07-13 <tytso@valinux.com>
949 * Release of E2fsprogs 1.19
951 2000-07-07 Theodore Ts'o <tytso@valinux.com>
953 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
954 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
955 list of filesystem flags supported by the library.
957 2000-07-04 Theodore Ts'o <tytso@valinux.com>
959 * ext2fs.h: Update to include latest journalling additions to the
962 * dll/jump.funcs: Add new jumptable entries for
963 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
964 ext2fs_badblocks_equal.
966 * tst_badblocks.c: Update test program to test
967 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
969 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
970 writes out bad blocks list to a file.
972 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
973 changes the callback function to take two additional
974 arguments; a private blind pointer supplied by the caller,
975 and pointer to a char * containing a pointer to the
978 * badblocks.c (ext2fs_badblocks_equal): Add new function which
979 returns true if two badblocks list are equal.
981 * Makefile.in: Remove explicit link of -lc in the shared library.
982 (It shouldn't be necessary, and is harmful in some cases).
984 2000-06-10 Theodore Ts'o <tytso@valinux.com>
986 * getsize.c (main): Add debugging code under #ifdef DEBUG
988 2000-05-27 Theodore Ts'o <tytso@valinux.com>
990 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
991 earlier, so that if there's an error reading it, we can
992 more cleanly back out of the operation.
994 2000-05-25 <tytso@snap.thunk.org>
996 * getsize.c (ext2fs_get_device_size): Use open64() instead of
997 open() if it exists. Under linux, manually define the
998 ioctl for BLKGETSIZE if it isn't already defined and it's
1001 * unix_io.c (unix_open): Use open64() instead of open() if it
1004 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1005 available (and prototypes are defined) use it in
1006 preference to llseek.
1008 * Makefile: Add hack dependency rule so that parallel makes work
1011 2000-05-18 Theodore Ts'o <tytso@valinux.com>
1013 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
1015 2000-04-03 Theodore Ts'o <tytso@valinux.com>
1017 * block.c: Readibility tweak in conditionals involving
1020 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
1021 how to define __s64 and __u64. Turn off "compression is
1022 experimental" warning if the cpp macro
1023 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
1025 2000-02-11 <tytso@snap.thunk.org>
1027 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
1028 Conditionally include Compression as a supported type if
1029 ENABLE_COMPRESSION (via --enable-compression) is turned on.
1031 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
1033 2000-02-08 <tytso@snap.thunk.org>
1035 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
1036 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1037 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
1038 Change to return the previous state of the bit that is
1039 being marked or unmarked. For speed optimization.
1041 2000-02-02 Theodore Ts'o <tytso@valinux.com>
1043 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
1045 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
1046 needed any more; we know it will always be i_generation.
1047 Add support for swapping the high bits of the uid and gid.
1049 1999-11-19 <tytso@valinux.com>
1051 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1052 counts if the link was successful. Patch suggested by
1055 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
1056 the source directory.
1058 1999-11-10 <tytso@valinux.com>
1060 * Release of E2fsprogs 1.18
1062 1999-11-08 <tytso@valinux.com>
1064 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1065 since ext2fs_badblocks_list_free was moved to freefs.c.
1067 * tst_badblocks.c: Use the newer badblocks API names. Add
1068 duplicate blocks to the test inputs to test dealing with
1069 adding blocks which are already in the badblocks list.
1071 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1072 of the list, use a shortcut O(1) operations instead of an
1073 O(n) operation. (Idea suggested by David Beattie.)
1075 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1076 of badblocks_list_free(), to save a procedure call.
1078 1999-10-26 <tytso@valinux.com>
1080 * Release of E2fsprogs 1.17
1082 1999-10-26 <tytso@valinux.com>
1084 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1085 seem to handle ~0UL the same way as they used to.
1087 1999-10-25 <tytso@valinux.com>
1089 * nt_io.c (_OpenNtName): Open the device using
1090 FILE_SYNCHRONOUS_IO_NONALERT instead of

1102 1999-10-22 <tytso@valinux.com>
1104 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1106 * link.c (ext2fs_link): This call now uses the low three bits of
1107 the flags parameter to pass the directory filetype
1108 information; it will set the directory entry FILETYPE
1109 information if the filesystem supports it.
1111 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1112 option is set, then create the '.' and '..' entries with
1113 the filetype set to EXT2_FT_DIR.
1115 1999-09-24 <tytso@valinux.com>
1117 * nt_io.c: New file which supports I/O under Windows NT.
1119 1999-09-07 <tytso@valinux.com>
1121 * ext2fs.h: Add new fields for journalling and define new
1122 feature bits used by newer filesystems: IMAGIC_INODES,
1123 HAS_JOURNAL, RECOVER.
1125 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1126 we update the inode block count and size files so that the
1127 block count field is updated correctly when we create an
1130 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1132 * Release of E2fsprogs 1.15
1134 1999-06-23 <tytso@valinux.com>
1136 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1137 kernels that use i_generation instead of i_version. Patch
1138 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1140 1999-06-21 <tytso@valinux.com>
1142 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1143 directory entry before calling the callback function.
1144 This should prevent some core dumps of insufficiently
1145 paranoid callback functions.
1147 1999-05-29 <tytso@rsts-11.mit.edu>
1149 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1151 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1152 that we don't handle writing yet (we do). Fixed bug where
1153 we weren't allocating a big enough buffer for ext2_bmap.
1155 1999-05-03 <tytso@rsts-11.mit.edu>
1157 * openfs.c (ext2fs_open): Check to make sure that the number of
1158 blocks per group is not zero --- if so, it must be a bad
1161 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1163 * Release of E2fsprogs 1.14
1165 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1167 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1168 the inode number is zero; if it's zero, return
1169 EXT2_ET_BAD_INODE_NUM.
1171 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1173 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1174 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2

1179 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1180 non-Linux case to use EINVAL by default, unless it isn't
1181 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1184 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1186 * Release of E2fsprogs 1.13
1188 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1190 * Makefile.in: Updated dependencies.
1192 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1194 * initialize.c (ext2fs_initialize): Make sure that we allocate
1195 enough inodes so that we can make a valid filesystem.
1197 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1199 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1201 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1202 function declaration.
1204 * dblist.c (make_dblist): Add safety check in case the dblist
1205 pointer passed in is null (in which case, assign it to
1206 fs->dblist). Fixed some signed/unsigned warnings.
1208 * bmap.c: Make addr_per_block be of type blk_t to avoid
1209 signed/unsigned warnings.
1211 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1212 function declaration.
1214 * get_pathname.c (get_pathname_proc): Use return value from
1215 ext2fs_get_mem, instead of checking if &gp->name is
1218 * dir_iterate.c (ext2fs_process_dir_block):
1219 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1220 from the function declaration.
1222 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1223 return the error directly instead of jumping to the
1224 cleanup routine, since we don't need to do any cleanup.
1226 * alloc_table.c (ext2fs_allocate_group_table): Make this
1227 function take a dgrp_t for its group argument.
1229 * ext2fs.h: Make dgrp_t an __u32 type, and make
1230 fs->desc_group_count be of type dgrp_t.
1232 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1234 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment

1240 * Release of E2fsprogs 1.12
1242 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1244 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1245 appropriate for all of the block group copies, so that
1246 it's clear where the beginning of the filesystem is on the
1247 disk. (For when the partition table gets scrod.)
1249 * ext2fs.h: Change the name of the feature from
1250 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1251 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1253 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1255 * inode.c (get_next_blockgroup): Fix bug where if
1256 get_next_blockgroup() is called early because of a missing
1257 inode table in a block group, the current_inode counter
1258 wasn't incremented correctly.
1260 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1262 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1263 against a completely trashed bad block inode.
1265 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1267 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1268 the stride length hits a bad value, we retry the block
1269 allocation starting at the beginning of the block group.
1271 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1272 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1273 e2_blkcnt_t to avoid collision with LFS API.
1275 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1277 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1278 way that avoids overflows on disk sizes greater than 4GB.
1280 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1282 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1283 return type for comparison functions for qsort.
1285 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1288 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1290 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1293 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1294 evade a potential problem with glibc's header files trying
1295 to spike out linux/types.h.
1297 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1298 include the old size of the memory, which is needed for
1299 some braindamaged memory allocation systems that don't
1302 * badblocks.c (ext2fs_badblocks_list_add):
1303 bb_inode.c (clear_bad_block_proc):

1307 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1308 pass the old size of the memory to be resized to
1309 ext2fs_resize_mem().
1311 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1313 * Makefile.in: Change to use new installation directory variables
1314 convention. Fix uninstall rules to take $(DESTDIR) into
1317 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1319 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1320 with 32 bit longs, then we need to manually define __s64
1321 and __u64, since the current kernel header files don't
1322 define these if __STRICT_ANSI__ is defined. This is a
1323 problem if we are compiling with full GCC warnings, since
1324 we do need 64 bit support.
1326 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1327 since we're not using ext2fs_move_blocks() and there
1328 is some question as to its usefulness in its current
1331 * bmap.c (block_bmap): Remove unused function.
1333 * bmove.c (process_block): Fix -Wall warning.
1335 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1337 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1338 contain the offset into the inode.i_blocks array when
1339 ref_block is zero. Since we haven't done a formal
1340 release of e2fsprogs since block_iterate2 was first
1341 introduced, I removed block_iterate2, and renamed
1342 block_iterate3 to be block_iterate2.
1344 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1345 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1346 use of block_iterate and block_iterate2 to
1347 block_iterate2 with the new prototype for the
1348 interator function. (using blkcnt_t forr blockcount)
1350 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1352 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1353 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1354 conditional defines of new features COMPAT_DIR_PREALLOC,
1355 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1356 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1357 the library to declare that we support COMPAT_DIR_PREALLOC,
1358 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1360 * fileio.c: Rename function ext2fs_file_llseek to be
1361 ext2fs_file_lseek, which is more accurate.
1363 * block.c: Add new function ext2fs_block_iterate3 which calls
1364 the iterator function with the blockcount argument of
1365 type blkcnt_t. This version of the function is
1366 allowed to handle large files; the other fucntions are
1369 * ext2fs.h: Add new type blkcnt_t
1371 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1373 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1374 field wasn't getting correctly incremented for sparse
1375 files when the indirect or doubly-indirect block
1376 specified in the inode was zero.
1378 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1380 * unlink.c (unlink_proc):
1381 * lookup.c (lookup_proc):
1382 * link.c (link_proc):
1383 * get_pathname.c (get_pathname_proc):
1384 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1385 from dirent->name_len, so it can be used for other
1388 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1389 and indicate that we have support for this incompatible

1399 number of directories when the block group information is
1402 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1404 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1405 inode table is missing so that we catch the case where the
1406 first block group is missing.
1408 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1411 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1413 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1415 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1417 * test_io.c (test_flush): Add a debugging printf when the flush
1420 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1421 read in, return right away.
1423 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1425 * bitops.h: Don't try to do i386 inline asm functions if the
1428 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1429 instead of linux/types.h, and e2_bitops.h instead of
1432 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1435 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1437 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1438 so that we don't need to call get_next_blockgroup() the
1439 first time around. Saves a bit of time, and prevents us
1440 from needing to assign -1 to current_group (which is an
1443 * icount.c (insert_icount_el): Cast the estimated number of inodes
1444 from a float to an ino_t.
1446 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

1483 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1485 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1486 paranoid about validating the directory counts from the
1487 block group information.
1489 * all files: Don't include stdlib.h anymore; include it in
1490 ext2_fs.h, since that file requires stdlib.h
1492 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1494 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1495 bitmap is loaded, and return an error if it is not.

1584 * inode.c (ext2fs_check_directory): Add support for the callback
1585 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
1587 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1589 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the

1609 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1611 * io.h: Change the prototype of ext2fs_llseek() to use int's
1612 instead of unsigned int's.
1614 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1615 to make life easer for GNU Libc 2.
1617 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1618 filesystem has its bitmaps stored as 32-bit words with bit
1619 0 as the LSB of each word. Thus a bitmap with only bit 0
1620 set would be, as a string of bytes, 00 00 00 01 00 ... To
1621 cope with this, we byte-reverse each word of a bitmap if
1622 we have a big-endian filesystem, that is, if we are *not*
1623 byte-swapping other word-sized numbers.
1625 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1690 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
1692 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1694 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1695 is zero, then return EXT2_IO_LLSEEK_FAILED.
1697 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1699 * Release of E2fsprogs 1.11
1701 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1703 * dblist.c (ext2fs_dblist_count): Added new function which returns
1704 the number of directory blocks in dblist.
1706 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1708 * unix_io.c (unix_flush): Make the io_channel flush function do a
1709 fsync to flush the kernel buffers to disk.
1711 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1713 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1714 current inode number wasn't being set by the
1715 goto_blockgroup function.
1717 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1719 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1720 of blocks which need to be moved, and moves those blocks
1721 to another location in the filesystem.
1723 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1724 bitmap, make sure all of the new parts of the bitmap are
1727 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1729 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1730 wasn't being returned to the caller.
1732 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1733 ext2fs_allocate_group_table() which sets the group tables
1734 for a particular block group. The relevant code was
1735 factored out of ext2fs_allocate_tables().
1737 * dblist.c (make_dblist): Adjust the initial size of the directory
1738 block list to be a bit more realistic (ten plus twice the
1739 number of directories in the filesystem).
1741 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1743 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1744 ext2fs_badblocks_list_test would test the list (and exceed
1745 array boundaries) if there were no bad blocks on the bad
1746 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1748 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1750 * Release of E2fsprogs version 1.10
1752 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1754 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1755 inode and block bitmaps based on the RAID 0 stride
1756 parameter (which is passed by mke2fs).
1758 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1759 mke2fs to communicate the stride length to
1760 ext2fs_allocate_tables()
1762 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1764 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1765 systems. (We can't assume that the new filesystem types
1768 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1770 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1771 allocate the inode and block bitmaps inside block group at
1774 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1776 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1777 filesystem has no free blocks, ext2fs_new_block would loop
1780 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1782 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only

1792 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1793 badblocks structure.
1795 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1799 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1801 (unix_close, test_close): Decrement the refcount and only
1802 close the io_channel if the refcount goes to 0.
1804 * io.h: Add refcount to the io_channel structure. Add new macro
1805 interface io_channel_bumpcount() to bump the refcount.
1807 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1809 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1810 cache in the filesystem handle, instead of the inode cache
1811 in a static variable.
1813 * freefs.c: Added static function to free the inode cache (called by
1816 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1818 * ext2fs.h: Added pointer to the inode_cache structure.
1820 * block.c (block_iterate_ind, block_iterate_dind,
1821 block_iterate_tind): If there are holes in the indirect,
1822 doubly indirect, or triply indirect blocks, increment the
1823 block count field automatically.
1825 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1827 * Release of E2fsprogs version 1.09
1829 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1831 * version.c (ext2fs_parse_version_string): Check the passed in
1832 version string (instead of the hard-coded one).
1834 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1835 greater filesystem size, clamp it to prevent allocating a
1836 block or inode bitmap beyond the filesystem.
1838 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1839 overhead calculation was accidentally removed.
1841 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1843 * Release of E2fsprogs version 1.08
1845 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1847 * dblist.c (ext2fs_set_dir_block): New function which sets the
1848 block of a dblist entry, given the directory inode and
1851 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1853 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1854 inode bitmaps at staggered locations across the block
1855 groups, to avoid concentrating the bitmaps on a small
1856 number of disks when using striped RAID arrays.
1858 * initialize.c (ext2fs_initialize): By default, choose the maximum
1859 possible number of blocks per group (based on the size of
1860 the bitmaps in the blocksize).
1862 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1864 * initialize.c (ext2fs_initialize): Add support for
1865 EXT2_COMPAT_SPARSE_SUPER feature.
1867 * closefs.c (ext2fs_bg_has_super): New function to determine
1868 whether or a particular block group should have a
1869 superblock and block group descriptor. Used for the
1870 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1871 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1872 or not the superblock should be written out for the block
1875 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1876 for sparse duplicate superblocks.
1878 * version.c (ext2fs_get_library_version): New function which
1879 returns the library version.
1881 * version.c (ext2fs_parse_version_string): New function which
1882 parses a version string and returns a version number,
1883 so application programs can compare version numbers as
1886 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1888 * icount.c (ext2fs_create_icount): Change function so that it also
1889 takes a new argument which contains a "hint" icount
1890 structure. This "hint" icount allows the create function
1891 to set up the sorted list in advance. This reduces
1892 significantly the amount of data moving needed to insert
1893 these inodes into the list later.
1895 * icount.c (ext2fs_icount_validate): New function which validates
1896 that the icount structure's rep invariant.
1898 * icount.c (get_icount_el): Completely revamped implementation
1899 to subsume put_icount_el(). Put_icount_el() used to
1900 use an O(N) implementation to insert in the middle
1901 of the icount list. It now uses a O(ln N) to search
1902 for where the icount should be inserted, and then uses
1903 a memcpy to move the list down (instead of a for loop).
1905 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1906 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1907 to see if the inode is within bounds; if it isn't, return
1910 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1911 when a bad inode number is passed to test_generic_bitmap
1912 to be EXT2FS_TEST_ERROR instead of the wrong
1913 EXT2FS_UNMARK_ERROR.
1915 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1917 * Release of E2fsprogs version 1.07
1919 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1921 * Makefile.in (ELF_VERSION): Change version to be 2.2
1923 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1925 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1926 ext2fs_fast_test_block_bitmap_range().
1928 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1929 ext2fs_test_block_bitmap_range: New inline functions which
1930 test to see whether a contiguous range of blocks is
1933 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1935 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1936 use ext2fs_badblocks_* instead of badblocks_*
1938 * bb_compat.c: New file which translates between old badblocks_*()
1939 names to ext2fs_badblocks_*()
1941 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1942 link.c (since e2fsck doesn't use ext2fs_unlink()).
1944 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1945 bitmap resizing routine moved from bitmaps.c, since e2fsck
1946 doesn't need to use this function.
1948 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1949 since e2fsck only needs ext2fs_lookup.
1951 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1953 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1954 already set; this is needed so that programs like dump
1955 which use the inode scan functions will deal with
1956 filesystems that have bad blocks in the inode table.
1958 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1960 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1961 Moved to ext2fsP.h, since it doesn't need to be part of
1962 the public interface.
1964 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1966 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1968 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1969 directory block list abstraction. (Code moved from
1972 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1973 to inode.c (since no one else should be peeking inside it!)
1975 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1977 * openfs.c (ext2fs_open): Check the feature set in the ext2
1978 superblock, and refuse to open filesystems if they contain
1979 incompatible features. (Can be overriden with the
1982 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1984 * block.c (ext2fs_block_iterate2): Added new function
1985 ext2fs_block_iterate2 which changes the function
1986 signature of the callback function to include the
1987 referencing block and offset.
1989 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1990 ext2fs_inode_scan_goto_blockgroup which allows an
1991 application to jump to a particular block group while
1992 doing an inode scan.
1994 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1996 * dirblock.c: Include string.h, since we use memcpy().
1998 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2000 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2001 a long not an int; this doesn't matter on i386 machines,
2002 but it does on Alpha's.
2004 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2006 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2007 table pointer is NULL, then return an error indicating
2008 that the inode table is missing.
2009 (get_next_blockgroup, get_next_blocks,
2010 ext2fs_get_next_inode): Don't treat a missing inode table
2011 as permanent error. Return MISSING_INODE_TABLE, but as an
2012 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
2014 * rw_bitmaps.c (ext2fs_write_block_bitmap,
2015 ext2fs_write_inode_bitmap): If the inode or block bitmap
2016 block is zero, then don't write out the inode or block
2017 bitmap. The idea here is to avoid stomping on the
2019 (read_bitmaps): If the inode or block bitmap block is
2020 zero, then fill in that portion of the inode or block
2021 bitmap with all zeros.
2023 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
2024 blocks in inode table when the inode table size is
2025 non-standard (and can therefore span blocks).
2027 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2029 * alloc.c (ext2fs_new_block): Fix fencepost error in
2030 ext2fs_new_block; make sure we don't try to allocate the
2031 first block beyond the end of the filesystem.
2033 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2035 * inode.c (check_for_inode_bad_blocks): New function called by
2036 get_next_blocks() to avoid reading in bad blocks marked in
2037 fs->badblocks. Inodes located in bad blocks are returned
2038 by ext2fs_get_next_inode() returns the error code
2039 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
2041 * alloc_tables.c (ext2fs_allocate_tables): New function which
2042 performs the part of mke2fs's job of allocating the
2045 * test_io.c (test_close): IO manager which is used for testing
2048 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2050 * inode.c (ext2fs_get_next_inode): Separate out the function of
2051 setting up for a new block group to get_next_blockgroup().
2052 Separate out the function of reading in blocks of the
2053 inode table to get_next_blocks().
2055 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
2057 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2058 blocks to the badblock list in sorted order. This allows
2059 badblocks_list_test to be coded using a binary search for
2062 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2064 * Release of E2fsprogs version 1.06
2066 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2068 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2069 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2072 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2073 set, then only write out the master superblock.
2075 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2077 * block.c (ext2fs_block_iterate): Fixed bug which caused
2078 block_iterate to fail to handle HURD created filesystems;
2079 it tested the inode translator field before the inode was
2082 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2084 * initialize.c (ext2fs_initialize): Make sure the description for

2105 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2106 for shortcut function fs->read_inode() and fs->write_inode().
2107 Added inode_cache to reduce CPU time spent in doing
2110 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
2113 * namei.c (ext2fs_follow_link): New function.
2114 (ext2fs_namei): Extended to have support for chasing
2115 symbolic links. ext2fs_namei() still returns an inode
2116 which is a symbolic link. Symbolic links are only chased
2117 while resolving the containing directory. To chase
2118 symbolic links of the final result, use
2119 ext2fs_follow_link().
2121 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2130 * initialize.c (ext2fs_initialize): On systems where the byte
2131 order is not i386 compatible, set the swap_byte flag.
2133 * inode.c (inocpy_with_swap): Check to see if inode contains a
2134 fast symlink before swapping the inode block fields. This
2135 required adding a new argument to inocpy_with_swap to
2136 determine whether the mode field is in host order or not.
2138 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2140 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2141 the sparc, if EXT2_STD_BITOPS set, use the standard
2142 i386-compatible bitmask operations, instead on the
2143 non-standard native bitmask operators.

2147 * block.c (ext2fs_block_iterate): Cause block iterator to return
2148 the HURD translator block (along with everything else).

2150 iterator, then don't return any meta data blocks
2151 (including the HURD translator).
2153 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2155 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2157 * uuid.c: New file, containing UUID utility functions.
2159 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2161 * ext2fs.h: Add a definition of the "real" ext2 superblock.

2165 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
2167 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2169 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2170 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2171 that's a basic value that must be correct for the rest of
2172 the library to work.
2174 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2177 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2188 Change the m68k bit numbering for bitmasks to match with
2189 the bit numbering used by all other ext2 implementations.
2191 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
2193 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

2216 when trying to determine its size.
2218 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
2220 * Release of E2fsprogs version 1.02

2224 * rw_bitops.c (ext2fs_write_block_bitmap):
2225 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2226 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2227 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2228 to avoid conflicts with with kernel include files. Also
2229 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2232 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2234 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
2236 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
2237 s_def_resuid and s_def_resgid for backwards compatibility.
2239 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

2243 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
2245 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
2248 * closefs.c: #include <string.h> to pick up memset() declaration
2250 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
2252 * Makefile.in: Added support for BSD shared libraries.
2254 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2257 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2259 * unix_io.c (unix_open): Add a double check; if the passed in name
2260 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2262 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2264 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

2271 * getsize.c (ext2fs_get_device_size): Add support for reading the
2272 partition size from a BSD disk label.

2286 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2287 Move these functions to freefs.c.
2289 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2290 descriptors shadow memory to keep purify quiet. (This
2291 also has the nice benefit that the unused portion of the
2292 shadow descriptors are zeroed out.)
2294 * dirblock.c (ext2fs_write_dir_block): We need to use
2295 dirent->rec_len *before* it's byteswapped to find the
2296 location of the next directory structure!
2298 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2299 cause ext2fs_new_inode to loop infinitely if we're trying
2300 to allocate an inode in group #0 and there are no free
2301 inodes at all in the system.
2303 * closefs.c: #include <errno.h> if it exists.
2305 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2307 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2313 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
2314 installation directories correctly.
2316 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>

2324 file containing functions for reading and writing
2325 directory blocks (byte swapping if necesssary)
2327 * block.c (block_iterate_ind, block_iterate_dind,
2328 block_iterate_tind): Byte swap the block addresses if
2329 EXT2_SWAP_BYTES is set (and swap them back before writing
2332 * inode.c (inocpy_with_swap): New function.

2334 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2336 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2337 the superblock and group descriptors before writing it out.
2339 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2340 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2341 and group descriptors.
2343 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2344 to desp ext2 filesystem structures.
2346 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2347 supplied by Pete A. Zaitcev so that the C language
2348 versions of these functions are more portable. They will
2349 now work on both little and big endian systems, and the
2350 assumption that 32-bit integers are used is gone.
2352 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2353 doing byte swapping.
2355 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2356 byte swapping should take place.
2358 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

2369 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2370 if the magic number is correct, it will be allocated.
2372 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2374 * block.c (block_iterate_ind, block_iterate_dind,
2375 block_iterate_tind): Don't recompute block_nr each loop;
2376 just increment it! Factor check of BLOCK_FLAG_APPEND out
2377 of the loop. Factor mask of BLOCK_CHANGED into changed
2378 variable out of the loop. (block_iterate_ind, in
2379 particular, gets called a lot, so every little
2380 optimization helps.)
2382 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2384 * block.c (block_iterate_ind, block_iterate_dind,

2389 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
2390 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2391 ext2fs_fast_test_inode_bitmap): Add fast version of these
2392 functions, which don't do range checking.

2395 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2396 ext2fs_get_inode_bitmap_end): Add new accessor functions
2397 which return the start and end points of the bitmaps.
2399 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2401 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2402 instead of llseek. The errno if the offset is too large
2403 and lseek is not supported should be EINVAL, not -EINVAL.
2405 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2407 * Makefile.in: Added support for ELF shared libraries.
2408 Fixed typos in the compilation rules.
2409 (distclean): Added Makefile.

2417 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
2419 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2421 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2423 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2424 the S_*, which are normally defined in <sys/stat.h>. This
2425 allows us to compile e2fsprogs on a non-Linux system,
2426 which may have a different value for S_IFDIR.
2428 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2430 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2431 this is a user-mode application!
2433 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2435 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2436 __linux__ so that non-linux systems won't see it.
2438 * alloc.c: Include <errno.h> if possible.
2439 * badblocks.c: Ditto.
2440 * bb_inode.c: Ditto.
2443 * expanddir.c: Ditto.
2444 * get_pathname.c: Ditto.
2445 * initialize.c: Ditto.
2452 * rw_bitmaps.c: Ditto.
2455 * Makefile.in: Rewritten to conform to GNU coding standards and
2456 support separate compilation directories.
2458 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2460 * initialize.c (ext2fs_initialize): Don't allow more than one
2461 bitmaps's worth of inodes in a group.
2463 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2465 * llseek.c (ext2_llseek): Added error checking to the llseek()
2466 compat code to protect against overflow. This only
2467 applies to 1.0 and early 1.1 kernels, which don't support
2468 the llseek() system call.
2470 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2472 * unix_io.c (unix_open): Initialize the read_error and write_error
2473 io_channel pointers to be null.
2475 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2476 found, clear it but don't try to update the filesystem
2477 accounting information, since that's hopeless anyway.
2479 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2480 bloblock_iterate_tind): Check to see if the indirect blocks are
2481 valid before trying to read them.

2487 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2488 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2489 illegal block or inode number is passed in, return instead
2490 of trying to test, set, or clear the bit.
2492 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2494 * Makefile: Added a dummy install target in case shared libraries

2508 the inode and block bitmaps.
2510 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2511 magic number for a block bitmap instead of an inode bitmap.

2560 structure magic numbers.
2562 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2563 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2564 someone uses the -b option to specify the use of the backup
2565 superblock --- this usually means that the main superblock is
2569 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2570 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2571 revision level to the superblock.

2580 * initialize.c: Completely revamped the inode and block bitmap
2581 structures, so that they can be better chance of being extensible
2582 in a shared library. They are now their own type, instead of
2583 being a char *. Also, the function signatures of
2584 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2585 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2586 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2587 changed to eliminate the ext2_filsys argument, since it is no

2592 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2593 system call if available.

2599 the creator operating system.
2601 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2603 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2604 the group descriptor statistics in addition to everything else.
2605 This relieves mke2fs of the responsibility of doing it.
