Ts'o * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap): 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. * closefs.c: #include if it exists. Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for BLOCK_FLAG_APPEND. Added documentation for the block interator flags.

Tue Jul 18 09:27:38 1995 * namei.c (process_dir_block): * mkdir.c (ext2fs_mkdir): * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block to read/write the directory block. * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New file containing functions for reading and writing directory blocks (byte swapping if necesssary) * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind): Byte swap the block addresses if EXT2_SWAP_BYTES is set (and swap them back before writing them out.) * inode.c (inocpy_with_swap): New function. (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode): 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. * openfs.c (ext2fs_open): If the magic number is byte-swapped, then set the EXT2_SWAP_BYTES and byte-swap the superblock and group descriptors. * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions 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 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end, ext2fs_compare_inode_bitmap_end): Added new file containing routines to compare bitmaps. * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP): Added new error codes. Sat Jul 15 04:23:37 1995 * 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 * 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 * 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 * llseek.c (ext2_llseek): If the offset is small enough, use lseek instead of llseek. The errno if the offset is too large and lseek is not supported should be EINVAL, not -EINVAL. Thu Jun 15 23:43:02 1995 Remy Card * Makefile.in: Added support for ELF shared libraries. Fixed typos in the compilation rules. (distclean): Added Makefile. * llseek.c (llseek): New function, if llseek() does not exist in the C library. (ext2_llseek): Changed to call llseek(). Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long. Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o * 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 . 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 * 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 * llseek.c: Put the include of inside the #ifdef __linux__ so that non-linux systems won't see it. * alloc.c: Include if possible. * badblocks.c: Ditto. * bb_inode.c: Ditto. * bitmaps.c: Ditto. * block.c: Ditto. * expanddir.c: Ditto. * get_pathname.c: Ditto. * initialize.c: Ditto. * inode.c: Ditto. * llseek.c: Ditto. * mkdir.c: Ditto. * namei.c: Ditto. * newdir.c: Ditto. * openfs.c: Ditto. * rw_bitmaps.c: Ditto. * unix_io.c: Ditto. * Makefile.in: Rewritten to conform to GNU coding standards and support separate compilation directories.

Ts'o * 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 * 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.

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.
