1 2005-03-21 Theodore Ts'o <tytso@mit.edu>
3 * Release of E2fsprogs 1.37
5 2005-03-21 Theodore Ts'o <tytso@mit.edu>
7 * ext2_ext_attr.h (EXT2_XATTR_LEN, EXT2_XATTR_SIZE): Add new
8 convenience cpp macros.
10 2005-03-20 Theodore Ts'o <tytso@mit.edu>
12 * mkdir.c (ext2fs_mkdir): Call ext2fs_write_new_inode() instead of
15 * inode.c (ext2fs_write_new_inode): New function which should be
16 used when the caller is writing an inode for the first
17 time. It makes sure that the extra portion of the large
18 inode is initialized properly.
20 2005-03-18 Theodore Ts'o <tytso@mit.edu>
22 * Makefile.in: Fix clean target to remove tst_getsectsize.
24 * getsize.c (ext2fs_get_device_size): Check to see if the number
25 of blocks is greater than 2**32 when we are doing a binary
26 search to determine the device size. Thanks to Stephen
27 Tweedie for the patch.

41 2005-02-03 Theodore Ts'o <tytso@mit.edu>
43 * bitops.c: Make the generic functions more efficient.
45 * bitops.h: Drop SPARC assembly code. It's less efficient than GCC
46 3.4 compiled code and also triggers nasty compiler
47 warnings on sparc64. Thanks to Matthias Andree for his
48 analysis and suggestion.
50 2005-01-27 Theodore Ts'o <tytso@mit.edu>
52 * res_gdt.c (ext2fs_create_resize_inode): Create the resize inode
53 even if s_reserved_gdt_blocks is zero.

63 * ext2_fs.h: Add new function prototypes
65 * ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr): The
66 ext2fs_swap_ext_attr() has been moved to swapfs.c, and
67 given a new argument, has_header.
69 * swapfs.c (ext2fs_swap_ext_attr): Moved from ext_attr.c, and
70 takes an argument which controls whether or not there is
71 an EA header which needs to be byteswaped.
72 (ext2fs_swap_inode_full): New function which byte-swaps
75 * inode.c (ext2fs_get_next_inode_full, ext2fs_read_inode_full,
76 ext2fs_write_inode_full): New functions, originally from
77 Alex Tomas, but which needed to be substantially fixed so
78 that the tests wouldn't cause major stack overwrite bugs
79 in byte-swapping is enabled.
81 2005-01-18 Theodore Ts'o <tytso@mit.edu>
83 * Makefile.in: Fix the kernel compile-time echo commands to be
84 consistent and portable
86 2005-01-07 Theodore Ts'o <tytso@mit.edu>
88 * unlink.c (ext2fs_unlink): If both the name and the inode number
89 are unspecified, then return an error, so that we don't do
90 something surprising such as unconditionally deleting the
91 first directory entry.
92 (unlink_proc): Delete directory entries by coalescing it
93 with the previous entry, to avoid directory fragmentation.
95 2005-01-06 Theodore Ts'o <tytso@mit.edu>
97 * version.c (ext2fs_parse_version_string): Change parsing
98 algorithm so that version strings such as 1.36-rc1 returns
99 a non-surprising result (i.e., 136, and not 1361).
101 2005-01-05 Theodore Ts'o <tytso@mit.edu>
103 * block.c (block_iterate_ind, block_iterate_dind,
104 block_iterate_tind): Move the code which byte swaps and
105 read/writes indirect blocks to ext2fs_{read,write}_ind_block.
106 This saves 400 bytes, and we need them for the
107 resize_inode handling.
109 * ind_block.c (ext2fs_read_ind_block, ext2fs_write_ind_block): New
112 * res_gdt.c (ext2fs_create_resize_inode): Use
113 ext2fs_{read,write}_ind_block so that byte swapping is
114 handled on big-endian systems.
116 * dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handle
117 has its own copy of the orig_super data structure. (This
118 is a better way of fixing a double-free problem in
119 resize2fs which Fedora attempted to fix in
120 e2fsprogs-1.35-double_free.patch. Addresses Red Hat
123 2004-12-23 Theodore Ts'o <tytso@mit.edu>
125 * inode.c (ext2fs_flush_icache): When flushing the icache, clear
126 the last-read block information as well.
128 * ext2fs.h (BMAP_SET), bmap.c (ext2fs_bmap): Add support for new
129 flag, BMAP_SET, which allows the caller to set a
130 particular logical->physical block mapping.
132 * ext2_err.et.in (EXT2_ET_SET_BMAP_NO_IND): New error code
134 * initialize.c (calc_reserved_gdt_blocks): #ifdef out all
135 debugging printf statements.
137 * res_gdt.c (ext2fs_create_resize_inode): Return
138 EXT2_ET_RESIZE_INODE_CORRUPT if the resize inode is not
139 what we expect. #ifdef out all debugging printf
142 * ext2_err.et.in (EXT2_ET_RESIZE_INODE_CORRUPT): Add new error code.

152 res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
153 ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
154 ext2fs_bg_has_super() back to closefs.c. There's no
155 reason for the new file, since list_backups() isn't being
156 used by any other functions, and can be made static, and
157 all users of the ext2fs filesystem will have to call
158 ext2fs_close() anyway.
160 2004-12-15 Theodore Ts'o <tytso@mit.edu>
162 * Applied resize inode patch from Andreas Dilger
164 * res_gdt.c (ext2fs_create_resize_inode): New function that
165 creates the resize inode.

173 Add function prototypes for res_gdt.c and sparse.c.
175 * closefs.c (ext2fs_super_and_bgd_loc): Take the reserved blocks
176 into account when calculating the number of overhead
179 * closefs.c (ext2fs_bg_has_super, test_root), sparse.c: Move these
180 functions to the new file sparse.c
182 * alloc_sb.c (ext2fs_reserve_super_and_bgd): Reserve the blocks
183 saved in the resize inode as being in use.
185 * ext2_err.et.in (EXT2_ET_RES_GDT_BLOCKS): Add new error code.
187 * Makefile.in (srcdir): Add res_gdt.c and sparse.c to the ext2fs

208 which adds a new parameter, io_options.
209 (ext2fs_open): If there is a question mark in the
210 filename, and no io_options are specified, assumed that
211 the text following the question mark are io_options.
213 * io_manager.c, Makefile.in: New source file which contains
214 high-level functions for the io_channel layer.
216 * freefs.c (ext2fs_free): Make sure we don't free the io_channel
219 * Makefile.in: Use Linux-kernel-style makefile output to make it
220 easier to see errors/warnings.
222 2004-11-29 Theodore Ts'o <tytso@mit.edu>
224 * ext2_fs.h (EXT2_EXTENTS_FL, EXT3_FEATURE_INCOMPAT_EXTENTS,
225 EXT2_MAX_BLOCK_LOG_SIZE): Add definition for extent
226 feature and inode flag. Change maximum allowable block
229 2004-10-08 Theodore Ts'o <tytso@mit.edu>
231 * getsize.c (ext2fs_get_device_size): Add support for Windows
232 9x/NT under Cygwin. Thanks to Sam Robb
233 (samrobb@users.sourceforge.net) for pointing this and the
234 suggested code patch.
236 2004-09-17 Theodore Ts'o <tytso@mit.edu>
238 * getsize.c: Clean up header #include's.
240 * llseek.c (ext2fs_llseek): On non-linux systems, use lseek64() if

246 block_iterate_dind, block_iterate_tind), inode.c
247 (ext2fs_read_inode): If EXT2_FLAG_IMAGE_FILE is set, so
248 read the metadata from fs->image_io instead of fs->io.

251 Initialize fs->image_io to be the same as fs->io.
253 * ext2_err.et.in (EXT2_ET_NOT_IMAGE_FILE): Add new error code.
255 * openfs.c (ext2fs_get_data_io, ext2fs_set_data_io,
256 ext2fs_rewrite_to_io): New functions that allow
257 applications to manipulate fs->image_io and fs->io safely.
259 * freefs.c (ext2fs_free): If fs->image_io is different fs->io,
260 then call io_channel_close on fs->image_io.
262 * ext2fs.h: Add image_io element to the ext2_filsys data
263 structure. Add ext2fs_get_data_io() ext2fs_set_data_io(),

268 * closefs.c (ext2fs_flush): Make sure the master superblock is
269 written last, and only after other I/O has been flushed to
270 disk. Thanks to Junfeng Yang from the Stanford
271 Metacompilation group for pointing a potential ordering
272 constraint problem if we don't write things out in the
275 * test_io.c: Implement the ability to abort after n reads or
276 writes to a particular block. The block is specified by
277 TEST_IO_BLOCK environment variable, and the read/write
278 count by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT
279 environment variables. The block data is now only dumped
280 if the 0x10 bit is set in TEST_IO_FLAGS.

287 2004-03-08 Theodore Ts'o <tytso@mit.edu>
289 * getsize.c (ext2fs_get_device_size): Only use the BLKGETSIZE64
290 ioctl on Linux 2.6 since it is unreliable in Linux 2.4.
291 (Addresses Debian Bug #236528). Fix typo in the ioctl
294 2004-03-02 Theodore Ts'o <tytso@mit.edu>
296 * getsize.c (ext2fs_get_device_size): Update getsize functions to
297 use Apple Darwin and Linux 64-bit ioctl's

322 which we're using due to a typo in the e2fsck code. (Oops)
324 * swapfs.c (ext2fs_swap_inode): Fix byte swap bug which causes SE
325 Linux created symlinks with mandatory attributes to fail
326 to be properly handled on big endian systems. (Addresses

329 superblock, including the journal backup fields.
331 2003-12-02 Theodore Ts'o <tytso@mit.edu>

337 rw_bitmaps.c, unix_io.c, unlink.c, write_bb_file.c: Fix
338 gcc -Wall complaints. Mainly marking variables as being
339 unsued, and catching signed vs. unsigned comparisons.

347 out where to write the superblock and block group
350 * alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
351 reserves space in the block bitmap using
352 ext2fs_super_and_bgd_loc.
354 * initialize.c (ext2fs_initialize): Use
355 ext2fs_reserve_super_and_bgd to initialize the block bitmap.
357 2003-08-20 Theodore Ts'o <tytso@mit.edu>

360 allows the caller to pass in the inode data structure.
362 * fileio.c (ext2fs_file_open2), ext2fs.h: Add new function which
363 allows the caller to pass in the inode to be used in the

448 Darwin systems when building with shared libraries.
450 2003-04-18 Theodore Ts'o <tytso@mit.edu>
452 * unix_io.c: Use __CYGWIN__ instead of CYGWIN.

492 * ext2_types.h.in: Don't redefine types if other e2fsprogs
493 *_types.h files have been included already.

537 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
538 unix_write_blk): Optimize routines so that we don't end up
539 searching the cache twice when a block isn't in the

541 let them go through the cache.
543 * unix_io.c (find_cached_block): Fixed bug which caused some clean
544 blocks to be erroneously marked as dirty, so they would
545 get written back to the disk before they are evicted from

563 were getting skipped.
565 2002-10-31 Theodore Ts'o <tytso@mit.edu>
567 * Release of E2fsprogs 1.30
569 2002-10-31 Theodore Ts'o <tytso@mit.edu>
571 * ext2_fs.h: Add support for a new inode flag, which is to be used
572 for indicating the top of directory hierarchies for the
573 Orlov block allocator.
575 * ismounted.c (check_mntent, check_mntent_file): Add better
576 support for loopback-mounted filesystems. Check /etc/mtab
577 if /proc/mounts doesn't turn up any mount flags, since
578 /etc/mtab has the loopback image filename, instead of
579 /dev/loop0. Also, check based on st_dev and st_ino, so
580 that if a relative pathname or a pathnames using symbolic
581 links are used, we can detect the the filesystem correctly
582 in those cases. (Addresses Sourceforge bug #619119)
584 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
585 don't try the FDFLUSH ioctl that was required for floppies
586 with older kernels. This avoids needless whining from the
587 MD device driver. (Addresses Sourceforge bug #545832).
589 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
590 wrong group_block to ext2fs_descriptor_block_loc if we're
591 using the backup superblock/block group descriptors.
592 (ext2fs_descriptor_block_loc): If we're using the backup
593 superblock descriptors, use the backup descriptor block in
594 the next block group.
596 2002-10-30 Theodore Ts'o <tytso@mit.edu>
598 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
599 table so that it buts up against the bitmap blocks, to
600 avoid block fragmentation.
602 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
603 bug; only allocate group descriptor blocks up to
606 2002-10-25 Theodore Ts'o <tytso@mit.edu>
608 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
609 know when a filesystem was created. (Sometimes this can
612 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
614 2002-10-20 Theodore Ts'o <tytso@valinux.com>
616 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
617 the journal data mode.
619 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
620 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
621 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
622 the meta_blockgroup filesystem format.
624 2002-10-15 <tytso@snap.thunk.org>
626 * ext2_fs.h: Add new field in superblock for default mount options.
628 2002-10-13 Theodore Ts'o <tytso@mit.edu>
630 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
633 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
635 * rw_bitmaps.c (ext2fs_write_block_bitmap,
636 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
637 because the bitmap is getting written to disk. Make
638 ext2fs_swap_bitmap be a static function, since it's not
639 intended to be exported.
641 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
643 2001-09-24 Theodore Tso <tytso@mit.edu>
645 * Release of E2fsprogs 1.29
647 2001-08-31 Theodore Tso <tytso@thunk.org>
649 * Release of E2fsprogs 1.28
651 2002-08-31 Theodore Ts'o <tytso@valinux.com>
653 * dblist.c (ext2fs_dblist_sort): New function which allows the
654 caller to pass in a special sort comparison function.
656 2002-08-20 Theodore Ts'o <tytso@mit.edu>
658 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
659 failed to accurately characterize non-standard slow
660 symlinks. (Which don't appear in practice on real-life
661 systems, fortunately.)
663 2002-08-17 Theodore Ts'o <tytso@mit.edu>
665 * Makefile.in: Remove inode_io.o from the standard object files,
666 and only build it if debugfs is enabled (it requires
667 fileio.o, which is only built if --disable-debugfs isn't
668 specified to configure).
670 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
671 incompatible way so that it is no longer
672 endian-dependent. Add the TEA hash. Allow the seed
673 parameter to be optional.
675 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
676 These features are all now in the HALF_MD4 hash. Add
677 definition for EXT2_HASH_TEA.
679 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
680 a pointer instead of an array.
682 2002-08-16 Theodore Ts'o <tytso@mit.edu>
684 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
686 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
687 the number of data blocks used by an inode exclusive of
690 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
691 adjusts the reference count in an extended attribute block.
693 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
694 correctly deal with extended attribute blocks in symbolic
697 2002-08-13 <tytso@snap.thunk.org>
699 * Makefile.in: Move dupfs.o and test_io.o from the
700 needed-by-debugfs object list to the needed-by-resizer
701 object list. Fixes compile problem if the system is built
702 with only --disable-debugfs.
704 2002-07-29 Theodore Ts'o <tytso@mit.edu>
706 * link.c (ext2fs_link): When adding a new link to a directory,
709 2002-07-23 Theodore Ts'o <tytso@mit.edu>
711 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
712 calculations for names > 32 characters to be completely
713 bogus. Changed MD4 calculation to match what is currently
714 being used in the CVS gkernel tree.
716 2002-07-19 Theodore Ts'o <tytso@mit.edu>
718 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
719 superblock definition.
721 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
722 create a set of u32_list functions.
724 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
725 since that's required by the directory indexing code.
727 2002-07-14 Theodore Ts'o <tytso@mit.edu>
729 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
730 using a C++ reserved word.
732 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
733 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
734 old version of glibc (built against 2.2 headers) will
735 interact badly with the workaround to actually cause more
736 problems. I hate it when the glibc folks think they're
737 being smarter than the kernel....
739 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
741 * ext2_fs.h: Add superblock field for reserved group descriptors.
743 2002-06-28 Theodore Ts'o <tytso@mit.edu>
745 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
746 ext2fs_cpu_to_{l,b}e{32,16}
748 2002-06-27 Theodore Ts'o <tytso@mit.edu>
750 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
751 Add appropriate fallbacks in this case.
753 2002-06-26 Theodore Ts'o <tytso@mit.edu>
755 * dirhash.c (ext2fs_dirhash): Change function signature to support
756 a hash seed, and to return the minor hash (for 64-bit hash
757 support). Add support for the half MD4, half MD4 with
758 seed, and half MD4 with seed and 64 bits.
760 2002-06-15 Theodore Ts'o <tytso@mit.edu>
762 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
764 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
766 * ext2_fs.h: Add macros for maximum block/inode counts:
767 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
768 and EXT2_MAX_INODES_PER_GROUP.
770 * openfs.c (ext2fs_open): Check that the number of blocks in a group
771 is less than 2^16, otherwise we need an INCOMPAT flag (not
772 in existence yet, if ever) to open such a filesystem.
774 * initialize.c (ext2fs_initialize): Limit the number of blocks and
775 inodes in a group to less than 2^16.
777 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
779 * ext2_fs.h: Further minor cleanups of the header. Consolidate
780 some checks for __KERNEL__ into one place.
782 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
784 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
785 the EXT2_SB() macro instead. Remove kernel function
786 prototypes also. This matches the 2.5 kernel, and
787 is also cleaner for other reasons. Whitespace cleanup.
789 2002-05-21 Theodore Ts'o <tytso@mit.edu>
791 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
793 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
795 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
797 * initialize.c (ext2fs_initialize): Remove assumption that
798 blocksizes are always <= 4k.
800 2002-05-11 Theodore Ts'o <tytso@mit.edu>
802 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
803 silently if inode pointer is NULL (and ext2fs_bmap is
804 expected to read the inode itself).
806 2002-04-27 Theodore Ts'o <tytso@mit.edu>
808 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
809 file we are checking is a block device file before looking
810 at st_rdev, since it's not valid for normal files.
811 (is_swap_device): Move so that it is outside the
812 HAVE_MNTENT_H, so that it is always built.
814 2002-03-11 Theodore Tso <tytso@mit.edu>
816 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
817 functions which take an extra flags argument. The flag
818 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
819 field is byte swampped on big-endian machines, since in
820 the V2 structure, name_len is a char field which is
821 doesn't need to be byte swapped --- except if an
822 old-style kernel had byte-swapped the name_len field
823 as part of the V1 structure.
825 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
827 * dirhash.c (ext2fs_dirhash): New function which calculates the
828 hash for a filename in an indexed directory.
830 2002-03-08 Theodore Tso <tytso@mit.edu>
832 * Release of E2fsprogs 1.27
834 2002-03-07 Theodore Tso <tytso@mit.edu>
836 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
838 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
839 tst_byteswap.c: Fix gcc -Wall complaints
841 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
842 (From Philipp Thomas <pthomas@suse.de>)
844 2002-02-25 Theodore Tso <tytso@mit.edu>
846 * ext2_fs.h: Add structure definitions for the directory indexing
849 2002-02-23 Theodore Tso <tytso@mit.edu>
851 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
852 it doesn't break things on mis32, sparc32, and alpha
855 2002-02-21 Theodore Tso <tytso@mit.edu>
857 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
858 we were missing an fclose().
860 2002-02-20 Theodore Tso <tytso@mit.edu>
862 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
863 abstraction interface which exports an ext2 inode.
865 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
866 as a public interface. Change void * to const void * in
867 ext2fs_file_write's interface.
869 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
870 conditional; save a few bytes.
872 2002-02-12 Theodore Tso <tytso@mit.edu>
874 * Makefile.in (tst_badblocks): Add some extra .o files when
875 linking the debugging program tst_badblocks which are
876 needed if we aren't compiling with inline functions enable.
878 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
879 define away __inline__ since it may not be supported.
881 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
882 stripped down jbd_debug that doesn't use variadic
883 arguments. This will cause warnings under AIX, but things
886 2002-02-03 Theodore Tso <tytso@thunk.org>
888 * Release of E2fsprogs 1.26
890 2002-02-03 Theodore Tso <tytso@mit.edu>
892 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
893 so that the number of directories in use is adjusted
896 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
897 which optionally will modify the number of directories
900 2002-01-03 Theodore Tso <tytso@mit.edu>
902 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
903 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
904 which will return deleted directory entries.
905 ext2fs_dir_iterate2 takes a new callback function which
906 is identical with the one used by
907 ext2fs_dblist_dir_iterate(). If the directory entry is
908 deleted, the callback function will be called with the
909 entry paraemter set to DIRENT_DELETED_FILE.
911 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
912 ext2fs_block_alloc_stats): New functions which update
913 block/inode allocation statistics in the bitmaps, block
914 group descriptors, and superblock.
916 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
917 expanddir.c (expand_dir_proc), bb_inode.c
918 (clear_bad_block_proc, set_bad_block_proc,
919 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
920 Update to use new block/inode allocation statistics.
922 2001-12-24 Theodore Tso <tytso@mit.edu>
924 * ismounted.c (is_swap_device): New function used by
925 ext2fs_check_if_mounted and ext2fs_check_mount_point which
926 determines whether or not the specified device is a swap
927 device by using /proc/swaps. More bulletproofing for
928 idiotic/careless system administrators!
930 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
931 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
932 field to struct_ext2_filsys, umask. This field is
933 initialize to 022, and affects ext2fs_mkdir in the obvious
934 way. (In the future umask should also affect new file
935 creation routines, but the fileio functions don't
936 currently support this yes.)
938 * ismounted.c (check_mntent_file): Stat all of the entries in
939 /etc/mtab and/or /proc/mounts in order to catch dim-witted
940 system administrators who might have created alias
943 2001-12-23 Theodore Tso <tytso@mit.edu>
945 * Makefile.in, jfs_user.h: Move linux/jbd.h to
946 ext2fs/kernel-jbd.h, to avoid using the system header
947 file version of hbd.h when using diet glibc (since it
948 forcibly adds /usr/include to the beginning of the
949 include search path.)
951 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
952 include/linux directory.
954 2001-12-16 Theodore Tso <tytso@mit.edu>
956 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
957 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
958 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
960 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
963 2001-12-03 Theodore Tso <tytso@mit.edu>
965 * unix_io.c (unix_open): Make sure the ulimit workaround works
966 regardless of the version of glibc which is used to
969 2001-11-26 Theodore Tso <tytso@mit.edu>
971 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
972 trying to unset the filesize limit if at all possible,
973 if a block device is getting opened. (The filesize limit
974 shouldn't be applied against writes to a block device, but
975 starting in 2.4.10, the kernel is doing this.)
977 2001-11-05 Theodore Tso <tytso@mit.edu>
979 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
980 file on adding a journal to an already-mounted filesystem,
981 try to clear the ext2 file attributes on an already
982 existing .journal file so that we don't fail if on a
983 partially added journal to the filesystem.
985 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
986 which signals that a particular inode should not have the
987 last bits of data (the "tail") be merged with another
988 file. This is necessary to keep LILO happy.
990 2001-09-20 Theodore Tso <tytso@thunk.org>
992 * Release of E2fsprogs 1.25
994 2001-09-16 Theodore Tso <tytso@mit.edu>
996 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
997 which was breaking the build on the Hurd. (Addresses
1000 2001-09-13 Theodore Ts'o <tytso@mit.edu>
1002 * ismounted.c (check_mntent_file): We now validate the entry in
1003 /etc/mtab to make sure the filesystem is really mounted,
1004 since some broken distributions (read: Slackware) have
1005 buggy boot scripts that don't initialize /etc/mtab before
1006 checking non-root filesystems. (Slackware also doesn't
1007 check the root filesystem separately, and reboot if the
1008 root filesystem had changes applied to it, which is
1009 dangerous and broken.)
1011 2001-09-02 Theodore Tso <tytso@thunk.org>
1013 * Release of E2fsprogs 1.24a
1015 2001-08-30 Theodore Tso <tytso@thunk.org>
1017 * Release of E2fsprogs 1.24
1019 2001-08-30 Theodore Tso <tytso@valinux.com>
1021 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
1022 changes, since the ioctl number has been reused by another
1025 2001-08-15 Theodore Tso <tytso@valinux.com>
1027 * Release of E2fsprogs 1.23
1029 2001-08-05 Theodore Tso <tytso@valinux.com>
1031 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
1032 version of the bitmap test routines to speed up these
1033 routines. (At some point I may want to make these
1034 routines use the find_first_bit functions, but that will
1035 add a lot of complexity since it means that these
1036 functions will have to break the bitmap abstraction
1037 boundary. It's not clear it's worth it.)
1039 * mkjournal.c (mkjournal_proc): Remember the last block allocated
1040 to speed up ext2fs_new_block().
1042 2001-07-29 Theodore Tso <tytso@valinux.com>
1044 * finddev.c (scan_dir): Fix memory leak; we weren't calling
1045 closedir() when exiting the function in all cases.
1047 2001-07-27 Theodore Tso <tytso@valinux.com>
1049 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
1050 block usable in the journal for external journals to be 2
1051 or 3, depending on the blocksize, so that the existing
1052 kernel code does the right thing.
1054 * getsize.c (ext2fs_get_device_size): Add support for the
1055 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
1056 from Ben LaHaise, but it's likely this interface won't
1059 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1060 when writing the journal superblock, too. (Oops! Needed
1061 to make 1k filesystems with external journal to work.)
1063 2001-07-26 Theodore Tso <tytso@valinux.com>
1065 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1066 to find the journal superblock if the blocksize is 1024.
1068 2001-07-21 Theodore Tso <tytso@valinux.com>
1070 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
1072 2001-07-20 Theodore Tso <tytso@valinux.com>
1074 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
1075 attribute block, set the filesystem changed bit.
1077 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1078 Comment out these functions since we're not using them.
1080 2001-07-10 Theodore Tso <tytso@valinux.com>
1082 * closefs.c (write_primary_superblock): After writing changes to
1083 the primary superblock, update the original superblock
1084 copy so we don't have to re-write those changes in the
1086 (ext2fs_flush): Clear the superblock dirty flag after
1087 we've flushed out changes to disk.
1089 2001-07-07 Theodore Tso <tytso@valinux.com>
1091 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
1092 to avoid register conflicts when compiling in PIC mode.
1094 2001-07-04 Theodore Tso <tytso@valinux.com>
1096 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1097 Add new functions (C and in i386 assembler) which quickly
1098 find bits set in a bitmask.
1100 2001-06-23 Theodore Tso <tytso@valinux.com>
1102 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
1103 ext2_ext_attr.h and ext_attr.c for extended attributes
1106 * Release of E2fsprogs 1.22
1108 2001-06-22 Theodore Tso <tytso@valinux.com>
1110 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
1111 descriptor so that adding a journal to a mounted
1112 filesystem doesn't die. (Fixes a bug accidentally
1113 introduced in e2fsprogs 1.21.)
1115 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
1116 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
1117 fchflags without defining UF_NODUMP. (Addresses Debian
1120 * flushb.c: Use platform independent method of defining the
1121 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
1122 since on newer glibc's BLKFLSBUF is defined there.
1124 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
1125 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
1126 to support byte swapping even if we don't support the
1127 conversion functions. (Fixes Debian bug #101686).
1129 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
1130 since the byte-swapping code all assumes the
1131 ext2_dir_entry structure. (It's a question of whether or
1132 not name_len should be byte-swapped or not, and whether
1133 it's a 16 bit or 8 bit field.)
1135 2001-06-15 Theodore Tso <tytso@valinux.com>
1137 * Release of E2fsprogs 1.21
1139 2001-06-15 Theodore Tso <tytso@valinux.com>
1141 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
1142 file which is generated and is therefore found in the
1143 build directory, not source directory.
1145 * ismounted.c (check_mntent_file): Use a test file in / to check
1146 to see if the root filesystem is mounted read-only. This
1147 protects against the case where /etc might not be on /, as
1148 well as the case where /etc/mtab doesn't exist. (Both are
1149 should-never happen scenarios, but you never know...)
1151 2001-06-14 Theodore Tso <tytso@valinux.com>
1153 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
1154 Remove unneeded #pragma argsused, since the arguments are
1157 2001-06-13 Theodore Tso <tytso@valinux.com>
1159 * ext2_types.h.in: If linux/types.h has been defined, then don't
1160 try to redefine the typedefs.
1162 * Makefile.in (HFILES): Add ext2_types.h to the list of files
1163 which should be installed.
1165 * ismounted.c (check_mntent_file): Work around GNU hurd brain
1166 damage. Addresses Debian bug #100304.
1168 * Makefile.in: Limit some .o files from being included into the
1169 library if --disable-debugfs, --disable-swapfs,
1170 --disable-imager, or --disable-resizer are used.
1172 2001-06-12 Theodore Tso <tytso@valinux.com>
1174 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
1175 function, and use the ext2fs_badblocks_* functions
1178 2001-06-11 Theodore Tso <tytso@valinux.com>
1180 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
1181 ext2fs_mark_generic_bitmap and
1182 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
1183 functions. (This saves space and doesn't significantly
1184 change the speed of e2fsck on a P-III.)
1186 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
1187 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
1188 include the byte-swapping logic if ENABLE_SWAPFS is turned
1189 on or if we're on a big-endian machine.
1191 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
1192 set EXT2_FLAG_SWAP_BYTES, instead of using
1195 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
1196 autoconf to determine whether or not return
1197 EXT2_FLAG_SWAP_BYTES.
1199 2001-06-10 Theodore Tso <tytso@valinux.com>
1201 * Makefile.in: Remove the dependence on the libe2p library.
1203 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
1204 with direct usage of the ioctl/fchflags so that we don't
1205 have to depend on the libe2p library.
1207 2001-06-08 Theodore Tso <tytso@valinux.com>
1209 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
1210 when trying to find a 32-bit wide type.
1212 * icount.c (insert_icount_el): Fix the code used to estimate the
1213 size of the new icount array to be more intelligent, to
1214 avoid reallocating the array too many times. Thanks to
1215 Enrique Perez-Terron for pointing this out.
1217 2001-06-02 Theodore Tso <tytso@valinux.com>
1219 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
1220 for a symlink to determine whether it is a fast symlink.
1222 2001-06-01 Theodore Tso <tytso@valinux.com>
1224 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
1225 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
1227 2001-05-25 Theodore Tso <tytso@valinux.com>
1229 * Release of E2fsprogs 1.20
1231 2001-05-25 Theodore Tso <tytso@valinux.com>
1233 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
1234 some to clean up Andreas's patches. Use strncpy instead
1235 of strcpy to save the root's mountpoint. Clean up #ifdef
1236 structure. Remove uneeded variable in testing/debug driver.
1238 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
1240 * ismounted.c: Add check for root device which doesn't depend on
1241 /etc/fstab or /proc/mounts to be correct. Don't call
1242 endmntent() before we are done with mnt struct.
1244 2001-05-23 Theodore Tso <tytso@valinux.com>
1246 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
1249 2001-05-21 Theodore Tso <tytso@valinux.com>
1251 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
1252 make room for pre-existing usage of
1253 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
1254 the same codepoint as EXT2_BTREE_FL.
1256 2001-05-20 Theodore Tso <tytso@valinux.com>
1258 * ext2fs.h: #include <> instead of "" for ext2fs and et header
1259 files, since they will be installed in /usr/include
1261 2001-05-14 Theodore Tso <tytso@valinux.com>
1263 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
1264 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1265 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
1266 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,
1267 expanddir.c, ext2_fs.h, fileio.c, finddev.c, flushb.c,
1268 freefs.c, get_pathname.c, getsize.c, icount.c, imager.c,
1269 initialize.c, inline.c, inode.c, irel_ma.c, ismounted.c,
1270 link.c, lookup.c, mkdir.c, mkjournal.c, namei.c, native.c,
1271 newdir.c, nt_io.c, openfs.c, read_bb.c, read_bb_file.c,
1272 rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c,
1273 tst_badblocks.c, tst_byteswap.c, tst_getsize.c,
1274 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
1275 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
1276 Adjust all files in this directroy to include this file.
1278 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
1281 2001-05-05 Theodore Tso <tytso@valinux.com>
1283 * fileio.c (ext2fs_file_read): Factored out common code and
1284 cleaned up function. Fixed a bug where if there was an
1285 error reading from the disk, the number of bytes read
1286 wasn't reliably set. (Fixes Debian bug #79163)
1287 (ext2fs_file_write): Factored out common code and made
1288 function more efficient; if writing a full block, don't
1289 bother to do a read-modify-write cycle.
1291 2001-05-04 Theodore Tso <tytso@valinux.com>
1293 * dirblock.c (ext2fs_read_dir_block): Check for an directory
1294 record length which isn't a multiple four, and treat that
1295 as an invalid. Scan the directory and return an error
1296 (EXT2_ET_DIR_CORRUPTED) if the directory records are
1298 (ext2fs_write_dir_block): If while byte-swapping the
1299 directory block, if there's an error, abort and return
1300 EXT2_ET_DIR_CORRUPTED.
1302 2001-05-02 Theodore Tso <tytso@valinux.com>
1304 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
1305 image_header field in the ext2_filsys structure
1307 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
1308 * inode.c (ext2fs_read_inode):
1309 * rw_bitmaps.c (read_bitmaps):
1310 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
1312 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
1313 sure the full bitmap is saved.
1315 2001-05-01 Theodore Tso <tytso@valinux.com>
1317 * e2image.h (struct ext2_image_hdr): Add space for the device name
1318 in the image header.
1320 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
1321 make sure the rec_len is a multiple of 4, to prevent
1322 bus-errors on architectures which care about mis-aligned
1325 2001-04-25 Theodore Tso <tytso@valinux.com>
1327 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
1328 query the device sizes using the BLKGETSIZE ioctl.
1330 2001-04-16 Theodore Tso <tytso@valinux.com>
1332 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
1333 before checking /etc/mtab. The EXT2_MF_READONLY flag is
1334 now set from the /etc/mtab options field for all
1335 filesystems, not just the root filesystem. Add debugging
1336 code to make it easier to test ext2fs_check_if_mounted().
1338 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
1339 check; return an error if there's an attempt to create a
1340 journal less than 1024 filesystem blocks.
1342 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
1343 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
1345 2001-02-20 Theodore Tso <tytso@valinux.com>
1347 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
1350 * tst_byteswap.c: New function to test the byteswap functions.
1351 Add to regression test suite.
1353 2001-02-08 Theodore Tso <tytso@valinux.com>
1355 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
1357 2001-02-07 Theodore Tso <tytso@valinux.com>
1359 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
1360 of s_first for external devices to always be 1, since
1361 jsb->s_first is always relative to the start of the
1362 journal superblock. Use htonl(1) when setting s_nr_users.
1364 2001-01-17 Theodore Ts'o <tytso@valinux.com>
1366 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
1367 device number of the filesystem (instead of the journal)
1368 was being dropped into s_journal_dev.
1370 2001-01-15 Theodore Ts'o <tytso@valinux.com>
1372 * initialize.c (ext2fs_initialize): Add support for initializing
1373 the ext2 superblock for external journal devices. This
1374 basically means we don't bother to allocate any block
1377 * openfs.c (ext2fs_open): Only open external journal devices if
1378 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
1379 ext2fs_open. When opening such devices, don't try to read
1380 the block group descriptors, since they're not there.
1382 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
1384 * mkjournal.c: Export a new function,
1385 ext2fs_create_journal_superblock(), which allocates and
1386 returns a buffer containing a journal superblock. This is
1387 needed by mke2fs to create an external journal. Rewrote
1388 ext2fs_add_journal_device() so that it no longer creates
1389 the external journal, but rather adds a filesystem to an
1390 existing external journal. It handles all of the UUID
1393 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
1394 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
1395 Changed function prototype for ext2fs_add_journal_device().
1397 2001-01-14 Theodore Ts'o <tytso@valinux.com>
1399 * closefs.c (ext2fs_flush): Don't write out anything beyond the
1400 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
1403 2001-01-12 Theodore Ts'o <tytso@valinux.com>
1405 * imager.c: Fix gcc -Wall complaints and a series of bugs where
1406 retval wasn't set correctly. (Thanks to Andreas Dilger
1407 for pointing this out.)
1409 2001-01-11 <tytso@snap.thunk.org>
1411 * flushb.c (ext2fs_sync_device): New function which centralizes
1412 all of the places which might try to use the BLKFLSBUF
1413 or FDFLUSH ioctls (and usually failing to define them
1414 since the system header files don't usually do this for
1415 us, and we're trying to avoid usage of kernel include
1418 2001-01-10 <tytso@snap.thunk.org>
1420 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
1421 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
1422 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
1423 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
1424 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
1425 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
1426 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
1427 ext2_ino_t, to protect applications that attempt to
1428 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
1429 changes ino_t(!?). So we use ext2_ino_t to avoid an
1430 unexpected ABI change.
1432 2001-01-05 <tytso@snap.thunk.org>
1434 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
1435 we may overrun allocated memory in case of a corrupted
1436 filesystem (or an e2fsck test case :-) when byte-swapping
1437 the directory block.
1439 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
1441 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
1442 complaints including a missing return 0 at the end of
1443 ext2fs_add_journal_device.
1445 2001-01-03 <tytso@snap.thunk.org>
1447 * Makefile.in: Link in libe2p when creating libext2fs as a shared
1448 library, since mkjournal.c now references fsetflags().
1450 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
1451 Dilger's changes (with fixups) to allow on-line creation
1454 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
1455 EXT2_FLAG_SUPER_ONLY, which the close routines to only
1456 update the superblock, and not the group descriptors.
1458 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
1460 * ismounted.c: add ext2fs_check_mount_point() function, which will
1461 optionally return the mount point of a device if mounted
1463 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
1465 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
1466 ext2fs_add_journal_inode()
1468 2001-01-01 <tytso@snap.thunk.org>
1470 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
1471 source (but not binary) compatibility of some users of the
1472 ext2 library. They should just simply do a global search
1473 and replace of struct ext2fs_sb with struct
1474 ext2_super_block, and use their own private copy of
1475 ext2_fs.h if they aren't already.
1477 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
1478 Replace use of ext2fs_sb with ext2_super_block.
1480 2000-12-31 <tytso@snap.thunk.org>
1482 * ext2fs.h: Cleaned up header file by removing definitions of
1483 feature flags that might not have been defined in older
1484 ext2 header files. Now that we're using our own
1485 include/linux/ext2fs.h header file, this can never happen.
1487 * jfs_dat.h: Removed old header file which is no longer needed.
1489 2000-12-13 Theodore Ts'o <tytso@valinux.com>
1491 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
1492 by Andreas Dilger to update the filesystem revision to
1495 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
1498 2000-12-09 <tytso@snap.thunk.org>
1500 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
1501 ext2fs_add_journal_device): Add a new argument to the APIs
1502 of these function, which is a flags word. This is used to
1503 allow the creation of a V1 superblock for those folks who
1504 are using ext3 0.3b in production. Note, the user-land
1505 interface for getting at this flag won't be documented, as
1506 the V1 superblock is deprecated.
1508 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
1509 which creates a V2 superblock instead of a V1 superblock.
1511 2000-11-21 <tytso@snap.thunk.org>
1513 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
1514 out by Andreas Dilger.
1516 2000-11-05 <tytso@snap.thunk.org>
1518 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
1519 ext2_fs.h, Makefile.in: New file that has routines that
1520 save ext2fs metadata to a file.
1522 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
1524 * e2image.h: New file which defines the file format for the ext2
1525 image file. (Saved copy of ext2 metadata to a file as a
1526 saving throw against worst-case damage.)
1528 2000-11-01 <tytso@snap.thunk.org>
1530 * inode.c (ext2fs_flush_icache): Add new function
1531 ext2fs_flush_icache() which flushes the internal inode
1532 cache. Applications which modify the inode table blocks
1533 directly must call this function.
1535 2000-10-26 <tytso@snap.thunk.org>
1537 * mkjournal.c: Add #include of netinet/in.h, since Solaris
1538 requires it for ntohl().
1540 * ext2_io.h (io_channel_write_byte): Add new interface to allow
1541 callers to write specific byte ranges. This is an
1542 optional interface, which not all IO channels may
1545 * unix_io.c (unix_write_byte):
1546 * test_io.c (test_write_byte): Add implementation of the
1547 write_byte function.
1549 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
1550 function which writes the primary superblock. If the IO
1551 channel supports writing raw bytes directly, only fields
1552 which were modified are written to the disk. This makes
1553 it safe(r) to use utilities like tune2fs on a mounted
1556 * freefs.c (ext2fs_free): Free the original superblock if it is
1559 * openfs.c (ext2fs_open): Store a copy of the original superblock
1562 * ext2fs.h: Add a field to store the original superblock in the
1563 ext2 context structure.
1565 2000-10-24 <tytso@snap.thunk.org>
1567 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
1568 don't need to use llseek).
1570 2000-10-24 <tytso@valinux.com>
1572 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
1573 creating an ext3 journal on a filesystem.
1575 2000-08-21 <tytso@valinux.com>
1577 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
1579 2000-08-22 <tytso@valinux.com>
1581 * unix_io.c: Make massive changes to support a multiple block
1582 writethrough cacheing.
1584 * ext2_io.h: Added flags field to the io_channel structure.
1586 2000-08-19 <tytso@valinux.com>
1588 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
1589 provides the function ext2fs_find_block_device(). This
1590 function returns the pathname to a block device, given its
1593 2000-07-13 <tytso@valinux.com>
1595 * Release of E2fsprogs 1.19
1597 2000-07-07 Theodore Ts'o <tytso@valinux.com>
1599 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
1600 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
1601 list of filesystem flags supported by the library.
1603 2000-07-04 Theodore Ts'o <tytso@valinux.com>
1605 * ext2fs.h: Update to include latest journalling additions to the
1608 * dll/jump.funcs: Add new jumptable entries for
1609 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1610 ext2fs_badblocks_equal.
1612 * tst_badblocks.c: Update test program to test
1613 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
1615 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
1616 writes out bad blocks list to a file.
1618 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
1619 changes the callback function to take two additional
1620 arguments; a private blind pointer supplied by the caller,
1621 and pointer to a char * containing a pointer to the
1624 * badblocks.c (ext2fs_badblocks_equal): Add new function which
1625 returns true if two badblocks list are equal.
1627 * Makefile.in: Remove explicit link of -lc in the shared library.
1628 (It shouldn't be necessary, and is harmful in some cases).
1630 2000-06-10 Theodore Ts'o <tytso@valinux.com>
1632 * getsize.c (main): Add debugging code under #ifdef DEBUG
1634 2000-05-27 Theodore Ts'o <tytso@valinux.com>
1636 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
1637 earlier, so that if there's an error reading it, we can
1638 more cleanly back out of the operation.
1640 2000-05-25 <tytso@snap.thunk.org>
1642 * getsize.c (ext2fs_get_device_size): Use open64() instead of
1643 open() if it exists. Under linux, manually define the
1644 ioctl for BLKGETSIZE if it isn't already defined and it's
1647 * unix_io.c (unix_open): Use open64() instead of open() if it
1650 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1651 available (and prototypes are defined) use it in
1652 preference to llseek.
1654 * Makefile: Add hack dependency rule so that parallel makes work
1657 2000-05-18 Theodore Ts'o <tytso@valinux.com>
1659 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
1661 2000-04-03 Theodore Ts'o <tytso@valinux.com>
1663 * block.c: Readibility tweak in conditionals involving
1666 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
1667 how to define __s64 and __u64. Turn off "compression is
1668 experimental" warning if the cpp macro
1669 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
1671 2000-02-11 <tytso@snap.thunk.org>
1673 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
1674 Conditionally include Compression as a supported type if
1675 ENABLE_COMPRESSION (via --enable-compression) is turned on.
1677 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
1679 2000-02-08 <tytso@snap.thunk.org>
1681 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
1682 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1683 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
1684 Change to return the previous state of the bit that is
1685 being marked or unmarked. For speed optimization.
1687 2000-02-02 Theodore Ts'o <tytso@valinux.com>
1689 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
1691 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
1692 needed any more; we know it will always be i_generation.
1693 Add support for swapping the high bits of the uid and gid.
1695 1999-11-19 <tytso@valinux.com>
1697 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1698 counts if the link was successful. Patch suggested by
1701 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
1702 the source directory.
1704 1999-11-10 <tytso@valinux.com>
1706 * Release of E2fsprogs 1.18
1708 1999-11-08 <tytso@valinux.com>
1710 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1711 since ext2fs_badblocks_list_free was moved to freefs.c.
1713 * tst_badblocks.c: Use the newer badblocks API names. Add
1714 duplicate blocks to the test inputs to test dealing with
1715 adding blocks which are already in the badblocks list.
1717 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1718 of the list, use a shortcut O(1) operations instead of an
1719 O(n) operation. (Idea suggested by David Beattie.)
1721 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1722 of badblocks_list_free(), to save a procedure call.
1724 1999-10-26 <tytso@valinux.com>
1726 * Release of E2fsprogs 1.17
1728 1999-10-26 <tytso@valinux.com>
1730 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1731 seem to handle ~0UL the same way as they used to.
1733 1999-10-25 <tytso@valinux.com>
1735 * nt_io.c (_OpenNtName): Open the device using
1736 FILE_SYNCHRONOUS_IO_NONALERT instead of
1737 FILE_SYNCHRONOUS_IO_ALERT
1738 (nt_open): At the end of the device open routine, unlock
1739 the drive but do not dismount it.
1741 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
1744 1999-10-22 <tytso@valinux.com>

1748 1999-10-22 <tytso@valinux.com>
1750 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1752 * link.c (ext2fs_link): This call now uses the low three bits of
1753 the flags parameter to pass the directory filetype
1754 information; it will set the directory entry FILETYPE
1755 information if the filesystem supports it.
1757 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1758 option is set, then create the '.' and '..' entries with
1759 the filetype set to EXT2_FT_DIR.
1761 1999-09-24 <tytso@valinux.com>
1763 * nt_io.c: New file which supports I/O under Windows NT.
1765 1999-09-07 <tytso@valinux.com>
1767 * ext2fs.h: Add new fields for journalling and define new
1768 feature bits used by newer filesystems: IMAGIC_INODES,
1769 HAS_JOURNAL, RECOVER.
1771 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1772 we update the inode block count and size files so that the
1773 block count field is updated correctly when we create an
1776 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1778 * Release of E2fsprogs 1.15
1780 1999-06-23 <tytso@valinux.com>
1782 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1783 kernels that use i_generation instead of i_version. Patch
1784 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1786 1999-06-21 <tytso@valinux.com>
1788 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1789 directory entry before calling the callback function.
1790 This should prevent some core dumps of insufficiently
1791 paranoid callback functions.
1793 1999-05-29 <tytso@rsts-11.mit.edu>
1795 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1797 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1798 that we don't handle writing yet (we do). Fixed bug where
1799 we weren't allocating a big enough buffer for ext2_bmap.
1801 1999-05-03 <tytso@rsts-11.mit.edu>
1803 * openfs.c (ext2fs_open): Check to make sure that the number of
1804 blocks per group is not zero --- if so, it must be a bad
1807 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1809 * Release of E2fsprogs 1.14
1811 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1813 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1814 the inode number is zero; if it's zero, return
1815 EXT2_ET_BAD_INODE_NUM.
1817 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1819 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1820 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1823 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1825 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1826 non-Linux case to use EINVAL by default, unless it isn't
1827 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1830 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1832 * Release of E2fsprogs 1.13
1834 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1836 * Makefile.in: Updated dependencies.
1838 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1840 * initialize.c (ext2fs_initialize): Make sure that we allocate
1841 enough inodes so that we can make a valid filesystem.
1843 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1845 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1847 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1848 function declaration.
1850 * dblist.c (make_dblist): Add safety check in case the dblist
1851 pointer passed in is null (in which case, assign it to
1852 fs->dblist). Fixed some signed/unsigned warnings.
1854 * bmap.c: Make addr_per_block be of type blk_t to avoid
1855 signed/unsigned warnings.
1857 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1858 function declaration.
1860 * get_pathname.c (get_pathname_proc): Use return value from
1861 ext2fs_get_mem, instead of checking if &gp->name is
1864 * dir_iterate.c (ext2fs_process_dir_block):
1865 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1866 from the function declaration.
1868 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1869 return the error directly instead of jumping to the
1870 cleanup routine, since we don't need to do any cleanup.
1872 * alloc_table.c (ext2fs_allocate_group_table): Make this
1873 function take a dgrp_t for its group argument.
1875 * ext2fs.h: Make dgrp_t an __u32 type, and make
1876 fs->desc_group_count be of type dgrp_t.
1878 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1880 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1881 than 10 blocks when we need to expand the size of the
1884 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1886 * Release of E2fsprogs 1.12
1888 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1890 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1891 appropriate for all of the block group copies, so that
1892 it's clear where the beginning of the filesystem is on the
1893 disk. (For when the partition table gets scrod.)
1895 * ext2fs.h: Change the name of the feature from
1896 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1897 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1899 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1901 * inode.c (get_next_blockgroup): Fix bug where if
1902 get_next_blockgroup() is called early because of a missing
1903 inode table in a block group, the current_inode counter
1904 wasn't incremented correctly.
1906 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1908 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1909 against a completely trashed bad block inode.
1911 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1913 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1914 the stride length hits a bad value, we retry the block
1915 allocation starting at the beginning of the block group.
1917 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1918 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1919 e2_blkcnt_t to avoid collision with LFS API.
1921 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1923 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1924 way that avoids overflows on disk sizes greater than 4GB.
1926 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1928 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1929 return type for comparison functions for qsort.
1931 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1934 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1936 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1939 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1940 evade a potential problem with glibc's header files trying
1941 to spike out linux/types.h.
1943 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1944 include the old size of the memory, which is needed for
1945 some braindamaged memory allocation systems that don't
1948 * badblocks.c (ext2fs_badblocks_list_add):
1949 bb_inode.c (clear_bad_block_proc):
1950 dblist.c (ext2fs_add_dir_block):
1951 icount.c (insert_icount_el):
1952 irel_ma.c (ima_put):
1953 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1954 pass the old size of the memory to be resized to
1955 ext2fs_resize_mem().
1957 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1959 * Makefile.in: Change to use new installation directory variables
1960 convention. Fix uninstall rules to take $(DESTDIR) into
1963 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1965 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1966 with 32 bit longs, then we need to manually define __s64
1967 and __u64, since the current kernel header files don't
1968 define these if __STRICT_ANSI__ is defined. This is a
1969 problem if we are compiling with full GCC warnings, since
1970 we do need 64 bit support.
1972 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1973 since we're not using ext2fs_move_blocks() and there
1974 is some question as to its usefulness in its current
1977 * bmap.c (block_bmap): Remove unused function.
1979 * bmove.c (process_block): Fix -Wall warning.
1981 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1983 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1984 contain the offset into the inode.i_blocks array when
1985 ref_block is zero. Since we haven't done a formal
1986 release of e2fsprogs since block_iterate2 was first
1987 introduced, I removed block_iterate2, and renamed
1988 block_iterate3 to be block_iterate2.
1990 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1991 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1992 use of block_iterate and block_iterate2 to
1993 block_iterate2 with the new prototype for the
1994 interator function. (using blkcnt_t forr blockcount)
1996 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1998 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1999 s_prealloc_blocks, s_prealloc_dir_blocks). Added
2000 conditional defines of new features COMPAT_DIR_PREALLOC,
2001 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
2002 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
2003 the library to declare that we support COMPAT_DIR_PREALLOC,
2004 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
2006 * fileio.c: Rename function ext2fs_file_llseek to be
2007 ext2fs_file_lseek, which is more accurate.
2009 * block.c: Add new function ext2fs_block_iterate3 which calls
2010 the iterator function with the blockcount argument of
2011 type blkcnt_t. This version of the function is
2012 allowed to handle large files; the other fucntions are
2015 * ext2fs.h: Add new type blkcnt_t
2017 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
2019 * block.c (ext2fs_block_iterate2): Fix bug where the block count
2020 field wasn't getting correctly incremented for sparse
2021 files when the indirect or doubly-indirect block
2022 specified in the inode was zero.
2024 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2026 * unlink.c (unlink_proc):
2027 * lookup.c (lookup_proc):
2028 * link.c (link_proc):
2029 * get_pathname.c (get_pathname_proc):
2030 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
2031 from dirent->name_len, so it can be used for other
2034 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
2035 and indicate that we have support for this incompatible
2038 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2040 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
2042 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2044 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
2045 number of directories when the block group information is
2048 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
2050 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
2051 inode table is missing so that we catch the case where the
2052 first block group is missing.
2054 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
2057 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2059 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
2061 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
2063 * test_io.c (test_flush): Add a debugging printf when the flush
2066 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
2067 read in, return right away.
2069 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2071 * bitops.h: Don't try to do i386 inline asm functions if the
2074 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
2075 instead of linux/types.h, and e2_bitops.h instead of
2078 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
2081 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2083 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
2084 so that we don't need to call get_next_blockgroup() the
2085 first time around. Saves a bit of time, and prevents us
2086 from needing to assign -1 to current_group (which is an
2089 * icount.c (insert_icount_el): Cast the estimated number of inodes
2090 from a float to an ino_t.
2092 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
2093 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

2102 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
2103 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
2104 defined, then assume all of the
2105 ext2-specific header files are in a flat directory.
2107 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
2108 all assignments from void * to be compatible with C++.

2112 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
2113 make sure the contents of the disk are flushed to disk.
2115 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2117 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
2118 avoid C++ namespace clash.
2120 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
2121 avoid C++ namespace clash.

2129 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2131 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
2132 paranoid about validating the directory counts from the
2133 block group information.
2135 * all files: Don't include stdlib.h anymore; include it in
2136 ext2_fs.h, since that file requires stdlib.h
2138 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2140 * expanddir.c (ext2fs_expand_dir): Check to make sure the block

2172 * [all files, basically]: Added definition of ext2fs_get_mem,
2173 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
2174 changed all library routines to use these wrapper functions.

2177 instead of the system error messages.
2179 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
2182 * ext2fs.h: Added function declarations and constants for bmap.c

2203 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
2204 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
2205 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
2207 * Change various library files to use these functions instead of
2208 EINVAL, ENOENT, etc.
2210 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2212 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we

2217 * Rename io.h to be ext2_io.h (avoid namespace collisions)
2219 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H

2257 * io.h: Change the prototype of ext2fs_llseek() to use int's
2258 instead of unsigned int's.
2260 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
2261 to make life easer for GNU Libc 2.
2263 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
2264 filesystem has its bitmaps stored as 32-bit words with bit
2265 0 as the LSB of each word. Thus a bitmap with only bit 0
2266 set would be, as a string of bytes, 00 00 00 01 00 ... To
2267 cope with this, we byte-reverse each word of a bitmap if
2268 we have a big-endian filesystem, that is, if we are *not*
2269 byte-swapping other word-sized numbers.

2329 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
2330 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c
2331 dirblock.c dupfs.c expanddir.c freefs.c get_pathname.c

2334 read_bb_file.c rs_bitmap.c rw_bitmaps.c swapfs.c
2335 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
2336 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
2338 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2340 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
2341 is zero, then return EXT2_IO_LLSEEK_FAILED.
2343 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
2345 * Release of E2fsprogs 1.11
2347 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2349 * dblist.c (ext2fs_dblist_count): Added new function which returns
2350 the number of directory blocks in dblist.
2352 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2354 * unix_io.c (unix_flush): Make the io_channel flush function do a
2355 fsync to flush the kernel buffers to disk.
2357 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2359 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
2360 current inode number wasn't being set by the
2361 goto_blockgroup function.
2363 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2365 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
2366 of blocks which need to be moved, and moves those blocks
2367 to another location in the filesystem.
2369 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
2370 bitmap, make sure all of the new parts of the bitmap are
2373 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2375 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
2376 wasn't being returned to the caller.
2378 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
2379 ext2fs_allocate_group_table() which sets the group tables
2380 for a particular block group. The relevant code was
2381 factored out of ext2fs_allocate_tables().
2383 * dblist.c (make_dblist): Adjust the initial size of the directory
2384 block list to be a bit more realistic (ten plus twice the
2385 number of directories in the filesystem).
2387 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2389 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
2390 ext2fs_badblocks_list_test would test the list (and exceed
2391 array boundaries) if there were no bad blocks on the bad
2392 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
2394 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2396 * Release of E2fsprogs version 1.10
2398 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2400 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
2401 inode and block bitmaps based on the RAID 0 stride
2402 parameter (which is passed by mke2fs).
2404 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
2405 mke2fs to communicate the stride length to
2406 ext2fs_allocate_tables()
2408 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2410 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
2411 systems. (We can't assume that the new filesystem types
2414 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2416 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
2417 allocate the inode and block bitmaps inside block group at
2420 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2422 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
2423 filesystem has no free blocks, ext2fs_new_block would loop
2426 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
2428 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
2429 free if refcount goes to zero.

2435 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
2438 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
2439 badblocks structure.
2441 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2443 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
2445 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
2447 (unix_close, test_close): Decrement the refcount and only
2448 close the io_channel if the refcount goes to 0.
2450 * io.h: Add refcount to the io_channel structure. Add new macro
2451 interface io_channel_bumpcount() to bump the refcount.
2453 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2455 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
2456 cache in the filesystem handle, instead of the inode cache
2457 in a static variable.
2459 * freefs.c: Added static function to free the inode cache (called by
2462 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
2464 * ext2fs.h: Added pointer to the inode_cache structure.
2466 * block.c (block_iterate_ind, block_iterate_dind,
2467 block_iterate_tind): If there are holes in the indirect,
2468 doubly indirect, or triply indirect blocks, increment the
2469 block count field automatically.
2471 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2473 * Release of E2fsprogs version 1.09
2475 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2477 * version.c (ext2fs_parse_version_string): Check the passed in
2478 version string (instead of the hard-coded one).
2480 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
2481 greater filesystem size, clamp it to prevent allocating a
2482 block or inode bitmap beyond the filesystem.
2484 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
2485 overhead calculation was accidentally removed.
2487 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2489 * Release of E2fsprogs version 1.08
2491 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

2494 block of a dblist entry, given the directory inode and
2497 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2499 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
2500 inode bitmaps at staggered locations across the block
2501 groups, to avoid concentrating the bitmaps on a small
2502 number of disks when using striped RAID arrays.
2504 * initialize.c (ext2fs_initialize): By default, choose the maximum
2505 possible number of blocks per group (based on the size of
2506 the bitmaps in the blocksize).
2508 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2510 * initialize.c (ext2fs_initialize): Add support for
2511 EXT2_COMPAT_SPARSE_SUPER feature.
2513 * closefs.c (ext2fs_bg_has_super): New function to determine
2514 whether or a particular block group should have a
2515 superblock and block group descriptor. Used for the
2516 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
2517 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
2518 or not the superblock should be written out for the block
2521 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
2522 for sparse duplicate superblocks.
2524 * version.c (ext2fs_get_library_version): New function which
2525 returns the library version.
2527 * version.c (ext2fs_parse_version_string): New function which
2528 parses a version string and returns a version number,
2529 so application programs can compare version numbers as
2532 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2534 * icount.c (ext2fs_create_icount): Change function so that it also
2535 takes a new argument which contains a "hint" icount
2536 structure. This "hint" icount allows the create function
2537 to set up the sorted list in advance. This reduces
2538 significantly the amount of data moving needed to insert
2539 these inodes into the list later.
2541 * icount.c (ext2fs_icount_validate): New function which validates
2542 that the icount structure's rep invariant.
2544 * icount.c (get_icount_el): Completely revamped implementation
2545 to subsume put_icount_el(). Put_icount_el() used to
2546 use an O(N) implementation to insert in the middle
2547 of the icount list. It now uses a O(ln N) to search
2548 for where the icount should be inserted, and then uses
2549 a memcpy to move the list down (instead of a for loop).
2551 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
2552 ext2fs_icount_increment, ext2fs_icount_decrement): Check
2553 to see if the inode is within bounds; if it isn't, return
2556 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
2557 when a bad inode number is passed to test_generic_bitmap
2558 to be EXT2FS_TEST_ERROR instead of the wrong
2559 EXT2FS_UNMARK_ERROR.
2561 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
2563 * Release of E2fsprogs version 1.07
2565 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2567 * Makefile.in (ELF_VERSION): Change version to be 2.2
2569 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2571 * alloc.c (ext2fs_get_free_blocks): Change routine to use
2572 ext2fs_fast_test_block_bitmap_range().
2574 * bitops.h (ext2fs_fast_test_block_bitmap_range,
2575 ext2fs_test_block_bitmap_range: New inline functions which
2576 test to see whether a contiguous range of blocks is
2579 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2581 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
2582 use ext2fs_badblocks_* instead of badblocks_*
2584 * bb_compat.c: New file which translates between old badblocks_*()
2585 names to ext2fs_badblocks_*()
2587 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
2588 link.c (since e2fsck doesn't use ext2fs_unlink()).
2590 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
2591 bitmap resizing routine moved from bitmaps.c, since e2fsck
2592 doesn't need to use this function.
2594 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
2595 since e2fsck only needs ext2fs_lookup.
2597 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2599 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
2600 already set; this is needed so that programs like dump
2601 which use the inode scan functions will deal with
2602 filesystems that have bad blocks in the inode table.
2604 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2606 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
2607 Moved to ext2fsP.h, since it doesn't need to be part of
2608 the public interface.
2610 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
2612 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2614 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
2615 directory block list abstraction. (Code moved from
2618 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
2619 to inode.c (since no one else should be peeking inside it!)
2621 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
2623 * openfs.c (ext2fs_open): Check the feature set in the ext2
2624 superblock, and refuse to open filesystems if they contain
2625 incompatible features. (Can be overriden with the
2628 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2630 * block.c (ext2fs_block_iterate2): Added new function
2631 ext2fs_block_iterate2 which changes the function
2632 signature of the callback function to include the
2633 referencing block and offset.
2635 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
2636 ext2fs_inode_scan_goto_blockgroup which allows an
2637 application to jump to a particular block group while
2638 doing an inode scan.
2640 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2642 * dirblock.c: Include string.h, since we use memcpy().
2644 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2646 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2647 a long not an int; this doesn't matter on i386 machines,
2648 but it does on Alpha's.
2650 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2652 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2653 table pointer is NULL, then return an error indicating
2654 that the inode table is missing.
2655 (get_next_blockgroup, get_next_blocks,
2656 ext2fs_get_next_inode): Don't treat a missing inode table
2657 as permanent error. Return MISSING_INODE_TABLE, but as an
2658 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
2660 * rw_bitmaps.c (ext2fs_write_block_bitmap,
2661 ext2fs_write_inode_bitmap): If the inode or block bitmap
2662 block is zero, then don't write out the inode or block
2663 bitmap. The idea here is to avoid stomping on the
2665 (read_bitmaps): If the inode or block bitmap block is
2666 zero, then fill in that portion of the inode or block
2667 bitmap with all zeros.
2669 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
2670 blocks in inode table when the inode table size is
2671 non-standard (and can therefore span blocks).
2673 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2675 * alloc.c (ext2fs_new_block): Fix fencepost error in
2676 ext2fs_new_block; make sure we don't try to allocate the
2677 first block beyond the end of the filesystem.
2679 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2681 * inode.c (check_for_inode_bad_blocks): New function called by
2682 get_next_blocks() to avoid reading in bad blocks marked in
2683 fs->badblocks. Inodes located in bad blocks are returned
2684 by ext2fs_get_next_inode() returns the error code
2685 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
2687 * alloc_tables.c (ext2fs_allocate_tables): New function which
2688 performs the part of mke2fs's job of allocating the
2691 * test_io.c (test_close): IO manager which is used for testing
2694 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2696 * inode.c (ext2fs_get_next_inode): Separate out the function of
2697 setting up for a new block group to get_next_blockgroup().
2698 Separate out the function of reading in blocks of the
2699 inode table to get_next_blocks().
2701 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
2703 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2704 blocks to the badblock list in sorted order. This allows
2705 badblocks_list_test to be coded using a binary search for
2708 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2710 * Release of E2fsprogs version 1.06
2712 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2714 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2715 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2718 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2719 set, then only write out the master superblock.
2721 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2723 * block.c (ext2fs_block_iterate): Fixed bug which caused
2724 block_iterate to fail to handle HURD created filesystems;
2725 it tested the inode translator field before the inode was
2728 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2730 * initialize.c (ext2fs_initialize): Make sure the description for
2731 the inode bitmap is set correctly.

2737 * Release of E2fsprogs version 1.05
2739 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2741 * initialize.c: Override the kernel's idea of default
2742 checkinterval from 0 (never) to 180 days.

2746 * namei.c (ext2fs_namei_follow): New function which follows
2747 symbolic link (if any) at the target.
2749 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2751 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2752 for shortcut function fs->read_inode() and fs->write_inode().
2753 Added inode_cache to reduce CPU time spent in doing

2759 * namei.c (ext2fs_follow_link): New function.
2760 (ext2fs_namei): Extended to have support for chasing
2761 symbolic links. ext2fs_namei() still returns an inode
2762 which is a symbolic link. Symbolic links are only chased
2763 while resolving the containing directory. To chase
2764 symbolic links of the final result, use
2765 ext2fs_follow_link().
2767 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2769 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2771 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2772 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

2776 * initialize.c (ext2fs_initialize): On systems where the byte
2777 order is not i386 compatible, set the swap_byte flag.
2779 * inode.c (inocpy_with_swap): Check to see if inode contains a
2780 fast symlink before swapping the inode block fields. This
2781 required adding a new argument to inocpy_with_swap to
2782 determine whether the mode field is in host order or not.
2784 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2786 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2787 the sparc, if EXT2_STD_BITOPS set, use the standard
2788 i386-compatible bitmask operations, instead on the
2789 non-standard native bitmask operators.
2791 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2793 * block.c (ext2fs_block_iterate): Cause block iterator to return
2794 the HURD translator block (along with everything else).
2795 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2796 iterator, then don't return any meta data blocks
2797 (including the HURD translator).
2799 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2801 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2803 * uuid.c: New file, containing UUID utility functions.
2805 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2807 * ext2fs.h: Add a definition of the "real" ext2 superblock.
2809 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2811 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
2813 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2815 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2816 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2817 that's a basic value that must be correct for the rest of
2818 the library to work.
2820 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2823 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2833 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
2834 Change the m68k bit numbering for bitmasks to match with
2835 the bit numbering used by all other ext2 implementations.
2837 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
2839 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
2840 ext2fs_open_inode_scan): Support dynamically-sized inodes.
2842 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>

2862 when trying to determine its size.
2864 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
2866 * Release of E2fsprogs version 1.02

2872 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2873 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2874 to avoid conflicts with with kernel include files. Also
2875 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2878 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2880 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
2882 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
2883 s_def_resuid and s_def_resgid for backwards compatibility.
2885 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
2887 * bitops.h: Added #ifdef's for Sparc.
2889 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
2891 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
2894 * closefs.c: #include <string.h> to pick up memset() declaration
2896 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
2898 * Makefile.in: Added support for BSD shared libraries.
2900 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2903 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2905 * unix_io.c (unix_open): Add a double check; if the passed in name
2906 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2908 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2910 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

2917 * getsize.c (ext2fs_get_device_size): Add support for reading the
2918 partition size from a BSD disk label.
2920 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2922 * getsize.c (ext2fs_get_device_size): New function that determins
2923 the size of a device. Used by mke2fs and e2fsck.
2925 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
2927 * Makefile.in (install): Install static libraries in $(ulibdir)
2928 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).

2932 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2933 Move these functions to freefs.c.
2935 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2936 descriptors shadow memory to keep purify quiet. (This
2937 also has the nice benefit that the unused portion of the
2938 shadow descriptors are zeroed out.)
2940 * dirblock.c (ext2fs_write_dir_block): We need to use
2941 dirent->rec_len *before* it's byteswapped to find the
2942 location of the next directory structure!
2944 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2945 cause ext2fs_new_inode to loop infinitely if we're trying
2946 to allocate an inode in group #0 and there are no free
2947 inodes at all in the system.
2949 * closefs.c: #include <errno.h> if it exists.
2951 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2953 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2959 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
2960 installation directories correctly.
2962 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
2964 * namei.c (process_dir_block):
2965 * mkdir.c (ext2fs_mkdir):
2966 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
2967 to read/write the directory block.

2970 file containing functions for reading and writing
2971 directory blocks (byte swapping if necesssary)
2973 * block.c (block_iterate_ind, block_iterate_dind,
2974 block_iterate_tind): Byte swap the block addresses if
2975 EXT2_SWAP_BYTES is set (and swap them back before writing
2978 * inode.c (inocpy_with_swap): New function.
2979 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
2980 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2982 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2983 the superblock and group descriptors before writing it out.
2985 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2986 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2987 and group descriptors.
2989 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2990 to desp ext2 filesystem structures.
2992 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2993 supplied by Pete A. Zaitcev so that the C language
2994 versions of these functions are more portable. They will
2995 now work on both little and big endian systems, and the
2996 assumption that 32-bit integers are used is gone.
2998 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2999 doing byte swapping.
3001 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
3002 byte swapping should take place.
3004 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

3015 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
3016 if the magic number is correct, it will be allocated.
3018 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
3020 * block.c (block_iterate_ind, block_iterate_dind,
3021 block_iterate_tind): Don't recompute block_nr each loop;
3022 just increment it! Factor check of BLOCK_FLAG_APPEND out
3023 of the loop. Factor mask of BLOCK_CHANGED into changed
3024 variable out of the loop. (block_iterate_ind, in
3025 particular, gets called a lot, so every little
3026 optimization helps.)
3028 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
3030 * block.c (block_iterate_ind, block_iterate_dind,
3031 block_iterate_tind): Precompute limit of loop to speed up
3032 block_iterate_ind and company.

3036 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
3037 ext2fs_fast_test_inode_bitmap): Add fast version of these
3038 functions, which don't do range checking.
3040 * bitops.h (ext2fs_get_block_bitmap_start,
3041 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
3042 ext2fs_get_inode_bitmap_end): Add new accessor functions
3043 which return the start and end points of the bitmaps.
3045 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
3047 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
3048 instead of llseek. The errno if the offset is too large
3049 and lseek is not supported should be EINVAL, not -EINVAL.
3051 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
3053 * Makefile.in: Added support for ELF shared libraries.
3054 Fixed typos in the compilation rules.
3055 (distclean): Added Makefile.
3057 * llseek.c (llseek): New function, if llseek() does not exist in the
3059 (ext2_llseek): Changed to call llseek().
3061 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3063 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.

3067 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
3069 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
3070 the S_*, which are normally defined in <sys/stat.h>. This
3071 allows us to compile e2fsprogs on a non-Linux system,
3072 which may have a different value for S_IFDIR.
3074 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3076 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
3077 this is a user-mode application!
3079 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
3081 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
3082 __linux__ so that non-linux systems won't see it.
3084 * alloc.c: Include <errno.h> if possible.
3085 * badblocks.c: Ditto.
3086 * bb_inode.c: Ditto.
3089 * expanddir.c: Ditto.
3090 * get_pathname.c: Ditto.
3091 * initialize.c: Ditto.
3098 * rw_bitmaps.c: Ditto.
3101 * Makefile.in: Rewritten to conform to GNU coding standards and
3102 support separate compilation directories.
3104 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
3106 * initialize.c (ext2fs_initialize): Don't allow more than one
3107 bitmaps's worth of inodes in a group.
3109 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
3111 * llseek.c (ext2_llseek): Added error checking to the llseek()
3112 compat code to protect against overflow. This only
3113 applies to 1.0 and early 1.1 kernels, which don't support
3114 the llseek() system call.
3116 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
3118 * unix_io.c (unix_open): Initialize the read_error and write_error
3119 io_channel pointers to be null.
3121 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
3122 found, clear it but don't try to update the filesystem
3123 accounting information, since that's hopeless anyway.
3125 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
3126 bloblock_iterate_tind): Check to see if the indirect blocks are
3127 valid before trying to read them.

3130 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
3132 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
3133 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
3134 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
3135 illegal block or inode number is passed in, return instead
3136 of trying to test, set, or clear the bit.
3138 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
3140 * Makefile: Added a dummy install target in case shared libraries
3143 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
3145 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
3146 the real last block of the bitmap should be calculated.

3150 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
3151 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
3152 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
3153 ext2fs_free_block_bitmap): Add magic number checking for
3154 the inode and block bitmaps.
3156 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
3157 magic number for a block bitmap instead of an inode bitmap.
3159 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
3160 magic number checking for the inode_scan structure.
3162 * badblocks.c (badblocks_list_free, badblocks_list_add,
3163 badblocks_list_test, badblocks_list_iterate_begin,
3164 badblocks_list_iterate, badblocks_list_iterate_end): Add
3165 magic number checking for the badblocks_list and
3166 badblocks_iterate structures.
3168 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
3169 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
3170 unix_write_blk, unix_flush): Add magic number checking
3171 both for io_channel structure and unix_private_data
3174 * openfs.c (ext2fs_open): Add check for io_manager structure's
3177 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
3178 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
3179 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
3180 * read_bb.c (ext2fs_read_bb_inode):
3181 * read_bb_file.c (ext2fs_read_bb_FILE):
3182 * newdir.c (ext2fs_new_dir_block):
3183 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
3184 * link.c (ext2fs_link, ext2fs_unlink):
3185 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
3186 ext2fs_write_inode, ext2fs_get_blocks,
3187 ext2fs_check_directory):
3188 * get_pathname.c (ext2fs_get_pathname):
3189 * expanddir.c (ext2fs_expand_dir):
3190 * block.c (ext2fs_block_iterate):
3191 * bitmaps.c (ext2fs_allocate_inode_bitmap,
3192 ext2fs_allocate_block_bitmap):
3193 * bb_inode.c (ext2fs_update_bb_inode):
3194 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
3195 * check_desc.c (ext2fs_check_desc):
3196 * closefs.c (ext2fs_close, ext2fs_flush):
3197 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
3202 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
3203 openfs.c into its own file.
3205 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
3206 structure magic numbers.
3208 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
3209 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
3210 someone uses the -b option to specify the use of the backup
3211 superblock --- this usually means that the main superblock is
3215 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
3216 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
3217 revision level to the superblock.
3219 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
3226 * initialize.c: Completely revamped the inode and block bitmap
3227 structures, so that they can be better chance of being extensible
3228 in a shared library. They are now their own type, instead of
3229 being a char *. Also, the function signatures of
3230 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
3231 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
3232 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
3233 changed to eliminate the ext2_filsys argument, since it is no
3236 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
3238 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
3239 system call if available.
3241 * llseek.c: new file. This is the stub calling the llseek system
3242 call which allows supports for 2GB+ file systems.
3244 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
3245 the creator operating system.
3247 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
3249 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
3250 the group descriptor statistics in addition to everything else.
3251 This relieves mke2fs of the responsibility of doing it.
3253 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
3254 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
3255 not the generic C function equivalents should be included or not.
3257 * openfs.c (ext2fs_open): If a superblock is specified, then use
3258 the backup group descriptors that go along with this superblock,
3259 instead of using the primary group descriptors. This allows
3260 e2fsck to recover filesystems where the primary group descriptors
