+
+ * ext2fs.h: Add feature definition for AFS IMAGIC inodes.

+ from the function declaration.
+
+ * block.c (ext2fs_block_iterate2): If the read_inode call fails,
+ return the error directly instead of jumping to the
+ cleanup routine, since we don't need to do any cleanup.
+
+ * alloc_table.c (ext2fs_allocate_group_table): Make this

+ disk. (For when the partition table gets scrod.)
+
+ * ext2fs.h: Change the name of the feature from
+ EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to

+
+ * inode.c (get_next_blockgroup): Fix bug where if

+
+ * read_bb.c (ext2fs_read_bb_inode): Make function more robust

+
+1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>

+
+ * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
+ expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be

+
+ * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a

+
+ * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
+ evade a potential problem with glibc's header files trying
+ to spike out linux/types.h.
+
+ * ext2fs.h (ext2fs_resize_mem): Change the function prototype to

+ account.
+
+1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
+ with 32 bit longs, then we need to manually define __s64
+ and __u64, since the current kernel header files don't
+ define these if __STRICT_ANSI__ is defined. This is a
+ problem if we are compiling with full GCC warnings, since
+ we do need 64 bit support.
+
+ * Makefile.in (OBJS): Remove bmove.o from files to be built,
+ since we're not using ext2fs_move_blocks() and there

+
+ * bmove.c (process_block): Fix -Wall warning.
+
+1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * block.c (ext2fs_block_iterate3): Make the ref_offset field
+ contain the offset into the inode.i_blocks array when
+ ref_block is zero. Since we haven't done a formal

+ introduced, I removed block_iterate2, and renamed
+ block_iterate3 to be block_iterate2.
+
+ * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
+ expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
+ use of block_iterate and block_iterate2 to
+ block_iterate2 with the new prototype for the
+ interator function. (using blkcnt_t forr blockcount)
+
+1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
+ s_prealloc_blocks, s_prealloc_dir_blocks). Added
+ conditional defines of new features COMPAT_DIR_PREALLOC,

+ INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
+ the library to declare that we support COMPAT_DIR_PREALLOC,
+ INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
+
+ * fileio.c: Rename function ext2fs_file_llseek to be
+ ext2fs_file_lseek, which is more accurate.
+
+ * block.c: Add new function ext2fs_block_iterate3 which calls
+ the iterator function with the blockcount argument of
+ type blkcnt_t. This version of the function is
+ allowed to handle large files; the other fucntions are
+ not.

+
+ * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
+
+ * block.c (ext2fs_block_iterate2): Fix bug where the block count
+ field wasn't getting correctly incremented for sparse
+ files when the indirect or doubly-indirect block
+ specified in the inode was zero.

+
+ * unlink.c (unlink_proc):
+ * lookup.c (lookup_proc):
+ * link.c (link_proc):
+ * get_pathname.c (get_pathname_proc):
+ * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
+ from dirent->name_len, so it can be used for other
+ purposes.
+
+ * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
+ and indicate that we have support for this incompatible
+ option.
+
+Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

+1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
+
+ * inode.c (ext2fs_get_next_inode): Always do the check to see if the

+
+ * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
+ needed.
+
+Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
+

+ read in, return right away.
+
+Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * bitops.h: Don't try to do i386 inline asm functions if the
+ compiler isn't GCC.
+
+ * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
+ instead of linux/types.h, and e2_bitops.h instead of
+ ext2fs/bitops.h.
+
+ * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
+ necessary.

+
+ * inode.c (ext2fs_open_inode_scan): Initialize the group variables
+ so that we don't need to call get_next_blockgroup() the

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

+
+ * badblocks.c (ext2fs_badblocks_list_test): Fix bug where

+ cache in the filesystem handle, instead of the inode cache
+ in a static variable.

+
+ * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and

+
+ * icount.c (ext2fs_create_icount): Change function so that it also
+ takes a new argument which contains a "hint" icount

+
+ * icount.c (ext2fs_icount_validate): New function which validates
+ that the icount structure's rep invariant.
+
+ * icount.c (get_icount_el): Completely revamped implementation

+ use an O(N) implementation to insert in the middle
+ of the icount list. It now uses a O(ln N) to search
+ for where the icount should be inserted, and then uses
+ a memcpy to move the list down (instead of a for loop).
+
+ * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
+ ext2fs_icount_increment, ext2fs_icount_decrement): Check
+ to see if the inode is within bounds; if it isn't, return
+ EINVAL.
+
+ * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
+ when a bad inode number is passed to test_generic_bitmap
+ to be EXT2FS_TEST_ERROR instead of the wrong

+ names to ext2fs_badblocks_*()
+
+ * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
+ link.c (since e2fsck doesn't use ext2fs_unlink()).
+
+ * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
+ bitmap resizing routine moved from bitmaps.c, since e2fsck
+ doesn't need to use this function.
+
+ * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
+ since e2fsck only needs ext2fs_lookup.
+
+Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
+ already set; this is needed so that programs like dump
+ which use the inode scan functions will deal with
+ filesystems that have bad blocks in the inode table.
+
+Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
+ Moved to ext2fsP.h, since it doesn't need to be part of
+ the public interface.
+
+ * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
+
+Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * dblist.c (ext2fs_get_num_dirs): New file, which implements a
+ directory block list abstraction. (Code moved from
+ e2fsck).
+
+ * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
+ to inode.c (since no one else should be peeking inside it!)
+
+ * valid_blk.c (ext2_inode_has_valid_blocks): New function.
+
+ * openfs.c (ext2fs_open): Check the feature set in the ext2
+ superblock, and refuse to open filesystems if they contain

+ EXT2_FLAG_FORCE
+
+Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * block.c (ext2fs_block_iterate2): Added new function
+ ext2fs_block_iterate2 which changes the function
+ signature of the callback function to include the
+ referencing block and offset.
+
+ * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
+ ext2fs_inode_scan_goto_blockgroup which allows an
+ application to jump to a particular block group while
+ doing an inode scan.
+
+Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * dirblock.c: Include string.h, since we use memcpy().
+
+Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
+ a long not an int; this doesn't matter on i386 machines,
+ but it does on Alpha's.

+Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
+ table pointer is NULL, then return an error indicating
+ that the inode table is missing.
+ (get_next_blockgroup, get_next_blocks,
+ ext2fs_get_next_inode): Don't treat a missing inode table
+ as permanent error. Return MISSING_INODE_TABLE, but as an
+ advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
+
+ * rw_bitmaps.c (ext2fs_write_block_bitmap,
+ ext2fs_write_inode_bitmap): If the inode or block bitmap
+ block is zero, then don't write out the inode or block
+ bitmap. The idea here is to avoid stomping on the
+ superblock.
+ (read_bitmaps): If the inode or block bitmap block is
+ zero, then fill in that portion of the inode or block
+ bitmap with all zeros.
+
+ * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
+ blocks in inode table when the inode table size is
+ non-standard (and can therefore span blocks).
+
+Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * alloc.c (ext2fs_new_block): Fix fencepost error in

+
+Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * inode.c (check_for_inode_bad_blocks): New function called by

+
+ * inode.c (ext2fs_get_next_inode): Separate out the function of
+ setting up for a new block group to get_next_blockgroup().
+ Separate out the function of reading in blocks of the
+ inode table to get_next_blocks().
+
+ * ext2fs.h: Add the badblocks list to the ext2_filsys entry
+
+ * badblocks.c (badblocks_list_add, badblocks_list_test): Add
+ blocks to the badblock list in sorted order. This allows
+ badblocks_list_test to be coded using a binary search for
+ speed.

+Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * block.c (ext2fs_block_iterate): Fixed bug which caused
+ block_iterate to fail to handle HURD created filesystems;
+ it tested the inode translator field before the inode was
+ loaded.
+
+Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * initialize.c (ext2fs_initialize): Make sure the description for

+ doing byte swapping.
+
+ * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

+
+ * block.c (block_iterate_ind, block_iterate_dind,

+
+ * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
