+
+ * 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.
+
+ * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
+ ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
+ ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
+ 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)
+
+ * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
+ the real last block of the bitmap should be calculated.
+
+Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
+
+ * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
+ ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
+ ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
+ ext2fs_free_block_bitmap): Add magic number checking for
+ the inode and block bitmaps.
+
+ * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
+ magic number for a block bitmap instead of an inode bitmap.
+
+ * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
+ magic number checking for the inode_scan structure.
+
+ * badblocks.c (badblocks_list_free, badblocks_list_add,
+ badblocks_list_test, badblocks_list_iterate_begin,
+ badblocks_list_iterate, badblocks_list_iterate_end): Add
+ magic number checking for the badblocks_list and
+ badblocks_iterate structures.
+
+ * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
+ * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
+ unix_write_blk, unix_flush): Add magic number checking
+ both for io_channel structure and unix_private_data
+ structure.
+
+ * openfs.c (ext2fs_open): Add check for io_manager structure's
+ magic number.
+
+ * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
+ ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
+ ext2fs_read_bitmaps, ext2fs_write_bitmaps):
+ * read_bb.c (ext2fs_read_bb_inode):
+ * read_bb_file.c (ext2fs_read_bb_FILE):
+ * newdir.c (ext2fs_new_dir_block):
+ * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
+ * link.c (ext2fs_link, ext2fs_unlink):
+ * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
+ ext2fs_write_inode, ext2fs_get_blocks,
+ ext2fs_check_directory):
+ * get_pathname.c (ext2fs_get_pathname):
+ * expanddir.c (ext2fs_expand_dir):
+ * block.c (ext2fs_block_iterate):
+ * bitmaps.c (ext2fs_allocate_inode_bitmap,
+ ext2fs_allocate_block_bitmap):
+ * bb_inode.c (ext2fs_update_bb_inode):
+ * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
+ * check_desc.c (ext2fs_check_desc):
+ * closefs.c (ext2fs_close, ext2fs_flush):
+ * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
+
+ * Makefile:
+ * ext2fs.h:
+ * openfs.c:
+ * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
+ openfs.c into its own file.
+
+ * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
+ 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
+ revision level to the superblock.

+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.
