Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* initialize.c: Override the kernel's idea of default
checkinterval from 0 (never) to 180 days.
Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* namei.c (ext2fs_namei_follow): New function which follows
symbolic link (if any) at the target.
Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
for shortcut function fs->read_inode() and fs->write_inode().
Added inode_cache to reduce CPU time spent in doing
byte swapping.
* swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
superblock.
* namei.c (ext2fs_follow_link): New function.
(ext2fs_namei): Extended to have support for chasing
symbolic links. ext2fs_namei() still returns an inode
which is a symbolic link. Symbolic links are only chased
while resolving the containing directory. To chase
symbolic links of the final result, use
ext2fs_follow_link().
Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.

* initialize.c (ext2fs_initialize): On systems where the byte
order is not i386 compatible, set the swap_byte flag.
* inode.c (inocpy_with_swap): Check to see if inode contains a
fast symlink before swapping the inode block fields. This
required adding a new argument to inocpy_with_swap to
determine whether the mode field is in host order or not.
Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
the sparc, if EXT2_STD_BITOPS set, use the standard
i386-compatible bitmask operations, instead on the
non-standard native bitmask operators.
Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* block.c (ext2fs_block_iterate): Cause block iterator to return
the HURD translator block (along with everything else).
If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
iterator, then don't return any meta data blocks
(including the HURD translator).
Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* gen_uuid.c: New file, which generates DCE-compatible UUIDs.

* openfs.c (ext2fs_open): If the blocksize in the superblock is
zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
that's a basic value that must be correct for the rest of
the library to work.
* ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
code.

the size of a device. Used by mke2fs and e2fsck.
Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
* Makefile.in (install): Install static libraries in $(ulibdir)

Move these functions to freefs.c.
* closefs.c (ext2fs_flush): If swapping blocks, clear the group
descriptors shadow memory to keep purify quiet. (This
also has the nice benefit that the unused portion of the
shadow descriptors are zeroed out.)
* dirblock.c (ext2fs_write_dir_block): We need to use
dirent->rec_len *before* it's byteswapped to find the
location of the next directory structure!
* alloc.c (ext2fs_new_inode): Fix bug which could potentially
cause ext2fs_new_inode to loop infinitely if we're trying
to allocate an inode in group #0 and there are no free
inodes at all in the system.

file containing functions for reading and writing
directory blocks (byte swapping if necesssary)

Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
* closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
the superblock and group descriptors before writing it out.

to desp ext2 filesystem structures.
* bitops.c (set_bit, clear_bit, test_bit): Use modifications
supplied by Pete A. Zaitcev so that the C language
versions of these functions are more portable. They will
now work on both little and big endian systems, and the
assumption that 32-bit integers are used is gone.
* bitops.h (ext2_swab16, ext2_swab32): Added new functions for
doing byte swapping.
* ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
byte swapping should take place.
Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
* inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
if the magic number is correct, it will be allocated.
Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
* block.c (block_iterate_ind, block_iterate_dind,
block_iterate_tind): Don't recompute block_nr each loop;
just increment it! Factor check of BLOCK_FLAG_APPEND out
of the loop. Factor mask of BLOCK_CHANGED into changed
variable out of the loop. (block_iterate_ind, in
particular, gets called a lot, so every little
optimization helps.)
Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
* block.c (block_iterate_ind, block_iterate_dind,
block_iterate_tind): Precompute limit of loop to speed up
block_iterate_ind and company.
* bitops.h (ext2fs_fast_mark_block_bitmap,
ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
ext2fs_fast_test_inode_bitmap): Add fast version of these
functions, which don't do range checking.
* bitops.h (ext2fs_get_block_bitmap_start,
ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
ext2fs_get_inode_bitmap_end): Add new accessor functions
which return the start and end points of the bitmaps.
Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
* llseek.c (ext2_llseek): If the offset is small enough, use lseek

and lseek is not supported should be EINVAL, not -EINVAL.
Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
* Makefile.in: Added support for ELF shared libraries.
Fixed typos in the compilation rules.
(distclean): Added Makefile.

Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
* ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
the S_*, which are normally defined in <sys/stat.h>. This
allows us to compile e2fsprogs on a non-Linux system,
which may have a different value for S_IFDIR.
Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
this is a user-mode application!
Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
* llseek.c: Put the include of <linux/unistd.h> inside the #ifdef

support separate compilation directories.
Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
* initialize.c (ext2fs_initialize): Don't allow more than one
bitmaps's worth of inodes in a group.
Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
* llseek.c (ext2_llseek): Added error checking to the llseek()
compat code to protect against overflow. This only
applies to 1.0 and early 1.1 kernels, which don't support
the llseek() system call.
Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
* unix_io.c (unix_open): Initialize the read_error and write_error
io_channel pointers to be null.
* bb_inode.c (clear_bad_block_proc): If an illegal block number is
found, clear it but don't try to update the filesystem
accounting information, since that's hopeless anyway.
* block.c (bloblock_iterate_ind, bloblock_iterate_dind,
bloblock_iterate_tind): Check to see if the indirect blocks are
valid before trying to read them.
* ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
EXT2_ET_BAD_TIND_BLOCK): Add new error codes.

illegal block or inode number is passed in, return instead
of trying to test, set, or clear the bit.
Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
* Makefile: Added a dummy install target in case shared libraries
are not built.
Mon Oct 24 14:11:44 1994 (tytso@rsx-11)

structure magic numbers.
* closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
the EXT2_VALID_FS flag in the backup superblock blocks, so that if
someone uses the -b option to specify the use of the backup
superblock --- this usually means that the main superblock is
toast. :-)
* ext2fs.h:
* ext2_err.et (EXT2_ET_REV_TOO_HIGH):
* openfs.c (ext2fs_open): Folded in Remy Card's changes to add a

Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
* ext2fs.h:
* bitmaps.c:
* bitops.c
* bitops.h:
* openfs.c:
* initialize.c: Completely revamped the inode and block bitmap
structures, so that they can be better chance of being extensible
in a shared library. They are now their own type, instead of
being a char *. Also, the function signatures of
ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
changed to eliminate the ext2_filsys argument, since it is no
longer necessary.
Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
* unix_io.c (unix_read_blk and unix_write_blk): use the llseek
system call if available.
* llseek.c: new file. This is the stub calling the llseek system
call which allows supports for 2GB+ file systems.
* initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
the creator operating system.
Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
* initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
the group descriptor statistics in addition to everything else.
This relieves mke2fs of the responsibility of doing it.
* bitops.c, bitops.h: Add assembly inline functions for the 68000.
Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
not the generic C function equivalents should be included or not.
* openfs.c (ext2fs_open): If a superblock is specified, then use
the backup group descriptors that go along with this superblock,
instead of using the primary group descriptors. This allows
e2fsck to recover filesystems where the primary group descriptors
have been trashed.
