1 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
3 * Makefile.in: Change to use new installation directory variables
4 convention. Fix uninstall rules to take $(DESTDIR) into
7 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
9 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
10 with 32 bit longs, then we need to manually define __s64
11 and __u64, since the current kernel header files don't
12 define these if __STRICT_ANSI__ is defined. This is a
13 problem if we are compiling with full GCC warnings, since
14 we do need 64 bit support.
16 * Makefile.in (OBJS): Remove bmove.o from files to be built,
17 since we're not using ext2fs_move_blocks() and there
18 is some question as to its usefulness in its current
21 * bmap.c (block_bmap): Remove unused function.
23 * bmove.c (process_block): Fix -Wall warning.
25 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
27 * block.c (ext2fs_block_iterate3): Make the ref_offset field
28 contain the offset into the inode.i_blocks array when
29 ref_block is zero. Since we haven't done a formal
30 release of e2fsprogs since block_iterate2 was first
31 introduced, I removed block_iterate2, and renamed
32 block_iterate3 to be block_iterate2.
34 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
35 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
36 use of block_iterate and block_iterate2 to
37 block_iterate2 with the new prototype for the
38 interator function. (using blkcnt_t forr blockcount)
40 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
42 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
43 s_prealloc_blocks, s_prealloc_dir_blocks). Added
44 conditional defines of new features COMPAT_DIR_PREALLOC,
45 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
46 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
47 the library to declare that we support COMPAT_DIR_PREALLOC,
48 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
50 * fileio.c: Rename function ext2fs_file_llseek to be
51 ext2fs_file_lseek, which is more accurate.
53 * block.c: Add new function ext2fs_block_iterate3 which calls
54 the iterator function with the blockcount argument of
55 type blkcnt_t. This version of the function is
56 allowed to handle large files; the other fucntions are
59 * ext2fs.h: Add new type blkcnt_t
61 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
63 * block.c (ext2fs_block_iterate2): Fix bug where the block count
64 field wasn't getting correctly incremented for sparse
65 files when the indirect or doubly-indirect block
66 specified in the inode was zero.
68 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
70 * unlink.c (unlink_proc):
71 * lookup.c (lookup_proc):
73 * get_pathname.c (get_pathname_proc):
74 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
75 from dirent->name_len, so it can be used for other
78 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
79 and indicate that we have support for this incompatible
82 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
84 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

89 number of directories when the block group information is
92 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
94 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
95 inode table is missing so that we catch the case where the
96 first block group is missing.
98 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
101 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
103 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
105 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
107 * test_io.c (test_flush): Add a debugging printf when the flush
110 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
111 read in, return right away.
113 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
115 * bitops.h: Don't try to do i386 inline asm functions if the
118 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
119 instead of linux/types.h, and e2_bitops.h instead of
122 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
125 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
127 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
128 so that we don't need to call get_next_blockgroup() the
129 first time around. Saves a bit of time, and prevents us
130 from needing to assign -1 to current_group (which is an
133 * icount.c (insert_icount_el): Cast the estimated number of inodes
134 from a float to an ino_t.

146 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
147 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
148 defined, then assume all of the
149 ext2-specific header files are in a flat directory.
151 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
152 all assignments from void * to be compatible with C++.
154 Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
156 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to

168 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
169 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
170 unlink.c: Change private to be priv_data (to avoid C++
173 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
175 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
176 paranoid about validating the directory counts from the
177 block group information.
179 * all files: Don't include stdlib.h anymore; include it in
180 ext2_fs.h, since that file requires stdlib.h
182 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
184 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
185 bitmap is loaded, and return an error if it is not.
186 (expand_dir_proc): Only use ext2fs_write_dir_block when
187 writing a directory block, not when writing out a fresh
190 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

216 * [all files, basically]: Added definition of ext2fs_get_mem,
217 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
218 changed all library routines to use these wrapper functions.
220 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND

307 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
308 filesystem has its bitmaps stored as 32-bit words with bit
309 0 as the LSB of each word. Thus a bitmap with only bit 0
310 set would be, as a string of bytes, 00 00 00 01 00 ... To
311 cope with this, we byte-reverse each word of a bitmap if
312 we have a big-endian filesystem, that is, if we are *not*
313 byte-swapping other word-sized numbers.

436 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
438 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>

499 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
500 cache in the filesystem handle, instead of the inode cache
501 in a static variable.

535 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
537 * dblist.c (ext2fs_set_dir_block): New function which sets the
538 block of a dblist entry, given the directory inode and
541 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
543 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
544 inode bitmaps at staggered locations across the block
545 groups, to avoid concentrating the bitmaps on a small
546 number of disks when using striped RAID arrays.
548 * initialize.c (ext2fs_initialize): By default, choose the maximum
549 possible number of blocks per group (based on the size of
550 the bitmaps in the blocksize).
552 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
554 * initialize.c (ext2fs_initialize): Add support for
555 EXT2_COMPAT_SPARSE_SUPER feature.
557 * closefs.c (ext2fs_bg_has_super): New function to determine
558 whether or a particular block group should have a
559 superblock and block group descriptor. Used for the
560 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
561 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
562 or not the superblock should be written out for the block
565 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
566 for sparse duplicate superblocks.
568 * version.c (ext2fs_get_library_version): New function which
569 returns the library version.
571 * version.c (ext2fs_parse_version_string): New function which
572 parses a version string and returns a version number,
573 so application programs can compare version numbers as
576 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
578 * icount.c (ext2fs_create_icount): Change function so that it also
579 takes a new argument which contains a "hint" icount
580 structure. This "hint" icount allows the create function
581 to set up the sorted list in advance. This reduces
582 significantly the amount of data moving needed to insert
583 these inodes into the list later.
585 * icount.c (ext2fs_icount_validate): New function which validates
586 that the icount structure's rep invariant.
588 * icount.c (get_icount_el): Completely revamped implementation
589 to subsume put_icount_el(). Put_icount_el() used to
590 use an O(N) implementation to insert in the middle
591 of the icount list. It now uses a O(ln N) to search
592 for where the icount should be inserted, and then uses
593 a memcpy to move the list down (instead of a for loop).
595 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
596 ext2fs_icount_increment, ext2fs_icount_decrement): Check
597 to see if the inode is within bounds; if it isn't, return
600 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
601 when a bad inode number is passed to test_generic_bitmap
602 to be EXT2FS_TEST_ERROR instead of the wrong
605 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
607 * Release of E2fsprogs version 1.07
609 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
611 * Makefile.in (ELF_VERSION): Change version to be 2.2
613 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
615 * alloc.c (ext2fs_get_free_blocks): Change routine to use
616 ext2fs_fast_test_block_bitmap_range().
618 * bitops.h (ext2fs_fast_test_block_bitmap_range,
619 ext2fs_test_block_bitmap_range: New inline functions which
620 test to see whether a contiguous range of blocks is
623 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
625 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
626 use ext2fs_badblocks_* instead of badblocks_*
628 * bb_compat.c: New file which translates between old badblocks_*()
629 names to ext2fs_badblocks_*()
631 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
632 link.c (since e2fsck doesn't use ext2fs_unlink()).
634 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
635 bitmap resizing routine moved from bitmaps.c, since e2fsck
636 doesn't need to use this function.
638 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
639 since e2fsck only needs ext2fs_lookup.
641 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
643 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
644 already set; this is needed so that programs like dump
645 which use the inode scan functions will deal with
646 filesystems that have bad blocks in the inode table.
648 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
650 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
651 Moved to ext2fsP.h, since it doesn't need to be part of
652 the public interface.
654 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
656 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
658 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
659 directory block list abstraction. (Code moved from
662 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
663 to inode.c (since no one else should be peeking inside it!)
665 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
667 * openfs.c (ext2fs_open): Check the feature set in the ext2
668 superblock, and refuse to open filesystems if they contain
669 incompatible features. (Can be overriden with the
672 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
674 * block.c (ext2fs_block_iterate2): Added new function
675 ext2fs_block_iterate2 which changes the function
676 signature of the callback function to include the
677 referencing block and offset.
679 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
680 ext2fs_inode_scan_goto_blockgroup which allows an
681 application to jump to a particular block group while
684 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
686 * dirblock.c: Include string.h, since we use memcpy().
688 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
690 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
691 a long not an int; this doesn't matter on i386 machines,
692 but it does on Alpha's.
694 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
696 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
697 table pointer is NULL, then return an error indicating
698 that the inode table is missing.
699 (get_next_blockgroup, get_next_blocks,
700 ext2fs_get_next_inode): Don't treat a missing inode table
701 as permanent error. Return MISSING_INODE_TABLE, but as an
702 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
704 * rw_bitmaps.c (ext2fs_write_block_bitmap,
705 ext2fs_write_inode_bitmap): If the inode or block bitmap
706 block is zero, then don't write out the inode or block
707 bitmap. The idea here is to avoid stomping on the
709 (read_bitmaps): If the inode or block bitmap block is
710 zero, then fill in that portion of the inode or block
711 bitmap with all zeros.
713 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
714 blocks in inode table when the inode table size is
715 non-standard (and can therefore span blocks).
717 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
719 * alloc.c (ext2fs_new_block): Fix fencepost error in
720 ext2fs_new_block; make sure we don't try to allocate the
721 first block beyond the end of the filesystem.
723 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
725 * inode.c (check_for_inode_bad_blocks): New function called by
726 get_next_blocks() to avoid reading in bad blocks marked in
727 fs->badblocks. Inodes located in bad blocks are returned
728 by ext2fs_get_next_inode() returns the error code
729 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
731 * alloc_tables.c (ext2fs_allocate_tables): New function which
732 performs the part of mke2fs's job of allocating the
735 * test_io.c (test_close): IO manager which is used for testing
738 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
740 * inode.c (ext2fs_get_next_inode): Separate out the function of
741 setting up for a new block group to get_next_blockgroup().
742 Separate out the function of reading in blocks of the
743 inode table to get_next_blocks().
745 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
747 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
748 blocks to the badblock list in sorted order. This allows
749 badblocks_list_test to be coded using a binary search for
752 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
754 * Release of E2fsprogs version 1.06
756 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
758 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
759 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
762 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
763 set, then only write out the master superblock.
765 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
767 * block.c (ext2fs_block_iterate): Fixed bug which caused
768 block_iterate to fail to handle HURD created filesystems;
769 it tested the inode translator field before the inode was
772 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
774 * initialize.c (ext2fs_initialize): Make sure the description for
775 the inode bitmap is set correctly.
777 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

781 * Release of E2fsprogs version 1.05
783 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
785 * initialize.c: Override the kernel's idea of default
786 checkinterval from 0 (never) to 180 days.
788 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
790 * namei.c (ext2fs_namei_follow): New function which follows
791 symbolic link (if any) at the target.
793 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
795 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
796 for shortcut function fs->read_inode() and fs->write_inode().
797 Added inode_cache to reduce CPU time spent in doing
800 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
803 * namei.c (ext2fs_follow_link): New function.
804 (ext2fs_namei): Extended to have support for chasing
805 symbolic links. ext2fs_namei() still returns an inode
806 which is a symbolic link. Symbolic links are only chased
807 while resolving the containing directory. To chase
808 symbolic links of the final result, use
809 ext2fs_follow_link().
811 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
813 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
815 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
816 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
818 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
820 * initialize.c (ext2fs_initialize): On systems where the byte
821 order is not i386 compatible, set the swap_byte flag.
823 * inode.c (inocpy_with_swap): Check to see if inode contains a
824 fast symlink before swapping the inode block fields. This
825 required adding a new argument to inocpy_with_swap to
826 determine whether the mode field is in host order or not.
828 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
830 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
831 the sparc, if EXT2_STD_BITOPS set, use the standard
832 i386-compatible bitmask operations, instead on the
833 non-standard native bitmask operators.
835 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
837 * block.c (ext2fs_block_iterate): Cause block iterator to return
838 the HURD translator block (along with everything else).
839 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
840 iterator, then don't return any meta data blocks
841 (including the HURD translator).
843 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
845 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
847 * uuid.c: New file, containing UUID utility functions.
849 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
851 * ext2fs.h: Add a definition of the "real" ext2 superblock.
853 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
855 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
857 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
859 * openfs.c (ext2fs_open): If the blocksize in the superblock is
860 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
861 that's a basic value that must be correct for the rest of
864 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
867 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
869 * Release of E2fsprogs version 1.04
871 Wed Mar 27 00:33:40 1996 <tytso@rsts-11.mit.edu>
873 * Release of E2fsprogs version 1.03
875 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
877 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
878 Change the m68k bit numbering for bitmasks to match with
879 the bit numbering used by all other ext2 implementations.
881 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
883 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

917 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
918 to avoid conflicts with with kernel include files. Also

922 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
924 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
926 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
927 s_def_resuid and s_def_resgid for backwards compatibility.
929 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

933 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
935 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
938 * closefs.c: #include <string.h> to pick up memset() declaration

950 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
952 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
954 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

967 the size of a device. Used by mke2fs and e2fsck.
969 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
971 * Makefile.in (install): Install static libraries in $(ulibdir)
972 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).

976 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
977 Move these functions to freefs.c.
979 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
980 descriptors shadow memory to keep purify quiet. (This
981 also has the nice benefit that the unused portion of the
982 shadow descriptors are zeroed out.)
984 * dirblock.c (ext2fs_write_dir_block): We need to use
985 dirent->rec_len *before* it's byteswapped to find the
986 location of the next directory structure!
988 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
989 cause ext2fs_new_inode to loop infinitely if we're trying
990 to allocate an inode in group #0 and there are no free
991 inodes at all in the system.
993 * closefs.c: #include <errno.h> if it exists.
995 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
997 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1014 file containing functions for reading and writing
1015 directory blocks (byte swapping if necesssary)
1017 * block.c (block_iterate_ind, block_iterate_dind,
1018 block_iterate_tind): Byte swap the block addresses if
1019 EXT2_SWAP_BYTES is set (and swap them back before writing
1022 * inode.c (inocpy_with_swap): New function.
1023 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1024 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.

1030 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1031 and group descriptors.

1034 to desp ext2 filesystem structures.
1036 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1037 supplied by Pete A. Zaitcev so that the C language
1038 versions of these functions are more portable. They will
1039 now work on both little and big endian systems, and the
1040 assumption that 32-bit integers are used is gone.
1042 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1043 doing byte swapping.
1045 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1046 byte swapping should take place.
1048 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1050 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
1051 ext2fs_compare_inode_bitmap_end): Added new file
1052 containing routines to compare bitmaps.
1054 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1055 Added new error codes.
1057 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1059 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1060 if the magic number is correct, it will be allocated.
1062 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1064 * block.c (block_iterate_ind, block_iterate_dind,
1065 block_iterate_tind): Don't recompute block_nr each loop;
1066 just increment it! Factor check of BLOCK_FLAG_APPEND out
1067 of the loop. Factor mask of BLOCK_CHANGED into changed
1068 variable out of the loop. (block_iterate_ind, in
1069 particular, gets called a lot, so every little
1070 optimization helps.)
1072 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1074 * block.c (block_iterate_ind, block_iterate_dind,
1075 block_iterate_tind): Precompute limit of loop to speed up
1076 block_iterate_ind and company.
1078 * bitops.h (ext2fs_fast_mark_block_bitmap,
1079 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1080 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1081 ext2fs_fast_test_inode_bitmap): Add fast version of these
1082 functions, which don't do range checking.
1084 * bitops.h (ext2fs_get_block_bitmap_start,
1085 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1086 ext2fs_get_inode_bitmap_end): Add new accessor functions
1087 which return the start and end points of the bitmaps.
1089 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1091 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1092 instead of llseek. The errno if the offset is too large
1093 and lseek is not supported should be EINVAL, not -EINVAL.
1095 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1097 * Makefile.in: Added support for ELF shared libraries.
1098 Fixed typos in the compilation rules.
1099 (distclean): Added Makefile.
1101 * llseek.c (llseek): New function, if llseek() does not exist in the
1103 (ext2_llseek): Changed to call llseek().
1105 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1107 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1109 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1111 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1113 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1114 the S_*, which are normally defined in <sys/stat.h>. This
1115 allows us to compile e2fsprogs on a non-Linux system,
1116 which may have a different value for S_IFDIR.
1118 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1120 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1121 this is a user-mode application!
1123 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1125 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1126 __linux__ so that non-linux systems won't see it.
1128 * alloc.c: Include <errno.h> if possible.
1129 * badblocks.c: Ditto.
1130 * bb_inode.c: Ditto.
1133 * expanddir.c: Ditto.
1134 * get_pathname.c: Ditto.
1135 * initialize.c: Ditto.
1142 * rw_bitmaps.c: Ditto.
1145 * Makefile.in: Rewritten to conform to GNU coding standards and
1146 support separate compilation directories.
1148 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1150 * initialize.c (ext2fs_initialize): Don't allow more than one
1151 bitmaps's worth of inodes in a group.
1153 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1155 * llseek.c (ext2_llseek): Added error checking to the llseek()
1156 compat code to protect against overflow. This only
1157 applies to 1.0 and early 1.1 kernels, which don't support
1158 the llseek() system call.
1160 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1162 * unix_io.c (unix_open): Initialize the read_error and write_error
1163 io_channel pointers to be null.
1165 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1166 found, clear it but don't try to update the filesystem
1167 accounting information, since that's hopeless anyway.
1169 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1170 bloblock_iterate_tind): Check to see if the indirect blocks are
1171 valid before trying to read them.
1173 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1174 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1176 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1177 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1178 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1179 illegal block or inode number is passed in, return instead
1180 of trying to test, set, or clear the bit.
1182 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1184 * Makefile: Added a dummy install target in case shared libraries
1187 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1189 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1190 the real last block of the bitmap should be calculated.
1192 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
1194 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1195 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1196 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1197 ext2fs_free_block_bitmap): Add magic number checking for
1198 the inode and block bitmaps.
1200 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1201 magic number for a block bitmap instead of an inode bitmap.
1203 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1204 magic number checking for the inode_scan structure.
1206 * badblocks.c (badblocks_list_free, badblocks_list_add,
1207 badblocks_list_test, badblocks_list_iterate_begin,
1208 badblocks_list_iterate, badblocks_list_iterate_end): Add
1209 magic number checking for the badblocks_list and
1210 badblocks_iterate structures.
1212 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1213 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1214 unix_write_blk, unix_flush): Add magic number checking
1215 both for io_channel structure and unix_private_data
1218 * openfs.c (ext2fs_open): Add check for io_manager structure's
1221 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1222 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1223 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1224 * read_bb.c (ext2fs_read_bb_inode):
1225 * read_bb_file.c (ext2fs_read_bb_FILE):
1226 * newdir.c (ext2fs_new_dir_block):
1227 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
1228 * link.c (ext2fs_link, ext2fs_unlink):
1229 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

1234 * block.c (ext2fs_block_iterate):
1235 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1236 ext2fs_allocate_block_bitmap):
1237 * bb_inode.c (ext2fs_update_bb_inode):
1238 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1239 * check_desc.c (ext2fs_check_desc):
1240 * closefs.c (ext2fs_close, ext2fs_flush):
1241 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1246 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1247 openfs.c into its own file.
1249 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1250 structure magic numbers.
1252 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1253 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1254 someone uses the -b option to specify the use of the backup
1255 superblock --- this usually means that the main superblock is
1259 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1260 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1261 revision level to the superblock.
1263 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1270 * initialize.c: Completely revamped the inode and block bitmap
1271 structures, so that they can be better chance of being extensible
1272 in a shared library. They are now their own type, instead of
1273 being a char *. Also, the function signatures of
1274 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1275 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1276 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1277 changed to eliminate the ext2_filsys argument, since it is no
1280 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1282 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1283 system call if available.
1285 * llseek.c: new file. This is the stub calling the llseek system
1286 call which allows supports for 2GB+ file systems.
1288 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1289 the creator operating system.
1291 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1293 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1294 the group descriptor statistics in addition to everything else.
1295 This relieves mke2fs of the responsibility of doing it.
1297 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1298 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1299 not the generic C function equivalents should be included or not.
1301 * openfs.c (ext2fs_open): If a superblock is specified, then use
1302 the backup group descriptors that go along with this superblock,
1303 instead of using the primary group descriptors. This allows
1304 e2fsck to recover filesystems where the primary group descriptors
