1 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
3 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
4 way that avoids overflows on disk sizes greater than 4GB.
6 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
8 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
9 return type for comparison functions for qsort.
11 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
14 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
16 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
19 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
20 evade a potential problem with glibc's header files trying
21 to spike out linux/types.h.
23 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
24 include the old size of the memory, which is needed for
25 some braindamaged memory allocation systems that don't
28 * badblocks.c (ext2fs_badblocks_list_add):
29 bb_inode.c (clear_bad_block_proc):
30 dblist.c (ext2fs_add_dir_block):

40 convention. Fix uninstall rules to take $(DESTDIR) into
43 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
45 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
46 with 32 bit longs, then we need to manually define __s64
47 and __u64, since the current kernel header files don't
48 define these if __STRICT_ANSI__ is defined. This is a
49 problem if we are compiling with full GCC warnings, since
50 we do need 64 bit support.
52 * Makefile.in (OBJS): Remove bmove.o from files to be built,
53 since we're not using ext2fs_move_blocks() and there
54 is some question as to its usefulness in its current

59 * bmove.c (process_block): Fix -Wall warning.
61 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
63 * block.c (ext2fs_block_iterate3): Make the ref_offset field
64 contain the offset into the inode.i_blocks array when
65 ref_block is zero. Since we haven't done a formal
66 release of e2fsprogs since block_iterate2 was first
67 introduced, I removed block_iterate2, and renamed
68 block_iterate3 to be block_iterate2.
70 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
71 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
72 use of block_iterate and block_iterate2 to
73 block_iterate2 with the new prototype for the
74 interator function. (using blkcnt_t forr blockcount)
76 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
78 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
79 s_prealloc_blocks, s_prealloc_dir_blocks). Added
80 conditional defines of new features COMPAT_DIR_PREALLOC,
81 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
82 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
83 the library to declare that we support COMPAT_DIR_PREALLOC,
84 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
86 * fileio.c: Rename function ext2fs_file_llseek to be
87 ext2fs_file_lseek, which is more accurate.
89 * block.c: Add new function ext2fs_block_iterate3 which calls
90 the iterator function with the blockcount argument of
91 type blkcnt_t. This version of the function is
92 allowed to handle large files; the other fucntions are
95 * ext2fs.h: Add new type blkcnt_t
97 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
99 * block.c (ext2fs_block_iterate2): Fix bug where the block count
100 field wasn't getting correctly incremented for sparse
101 files when the indirect or doubly-indirect block
102 specified in the inode was zero.
104 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
106 * unlink.c (unlink_proc):
107 * lookup.c (lookup_proc):
108 * link.c (link_proc):
109 * get_pathname.c (get_pathname_proc):
110 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
111 from dirent->name_len, so it can be used for other
114 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
115 and indicate that we have support for this incompatible
118 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
120 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

125 number of directories when the block group information is
128 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
130 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
131 inode table is missing so that we catch the case where the
132 first block group is missing.
134 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
137 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
139 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
141 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
143 * test_io.c (test_flush): Add a debugging printf when the flush
146 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
147 read in, return right away.
149 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
151 * bitops.h: Don't try to do i386 inline asm functions if the
154 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
155 instead of linux/types.h, and e2_bitops.h instead of
158 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
161 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
163 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
164 so that we don't need to call get_next_blockgroup() the
165 first time around. Saves a bit of time, and prevents us
166 from needing to assign -1 to current_group (which is an
169 * icount.c (insert_icount_el): Cast the estimated number of inodes
170 from a float to an ino_t.

182 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
183 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
184 defined, then assume all of the
185 ext2-specific header files are in a flat directory.
187 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
188 all assignments from void * to be compatible with C++.

209 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
211 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
212 paranoid about validating the directory counts from the
213 block group information.
215 * all files: Don't include stdlib.h anymore; include it in
216 ext2_fs.h, since that file requires stdlib.h
218 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
220 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
221 bitmap is loaded, and return an error if it is not.
222 (expand_dir_proc): Only use ext2fs_write_dir_block when

343 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
344 filesystem has its bitmaps stored as 32-bit words with bit
345 0 as the LSB of each word. Thus a bitmap with only bit 0
346 set would be, as a string of bytes, 00 00 00 01 00 ... To
347 cope with this, we byte-reverse each word of a bitmap if
348 we have a big-endian filesystem, that is, if we are *not*
349 byte-swapping other word-sized numbers.

471 array boundaries) if there were no bad blocks on the bad
472 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
474 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
476 * Release of E2fsprogs version 1.10

535 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
536 cache in the filesystem handle, instead of the inode cache
537 in a static variable.
539 * freefs.c: Added static function to free the inode cache (called by
542 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
544 * ext2fs.h: Added pointer to the inode_cache structure.
546 * block.c (block_iterate_ind, block_iterate_dind,
547 block_iterate_tind): If there are holes in the indirect,
548 doubly indirect, or triply indirect blocks, increment the
549 block count field automatically.
551 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
553 * Release of E2fsprogs version 1.09
555 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
557 * version.c (ext2fs_parse_version_string): Check the passed in
558 version string (instead of the hard-coded one).
560 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
561 greater filesystem size, clamp it to prevent allocating a
562 block or inode bitmap beyond the filesystem.
564 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
565 overhead calculation was accidentally removed.
567 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
569 * Release of E2fsprogs version 1.08
571 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
573 * dblist.c (ext2fs_set_dir_block): New function which sets the
574 block of a dblist entry, given the directory inode and
577 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
579 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
580 inode bitmaps at staggered locations across the block
581 groups, to avoid concentrating the bitmaps on a small
582 number of disks when using striped RAID arrays.
584 * initialize.c (ext2fs_initialize): By default, choose the maximum
585 possible number of blocks per group (based on the size of
586 the bitmaps in the blocksize).
588 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
590 * initialize.c (ext2fs_initialize): Add support for
591 EXT2_COMPAT_SPARSE_SUPER feature.
593 * closefs.c (ext2fs_bg_has_super): New function to determine
594 whether or a particular block group should have a
595 superblock and block group descriptor. Used for the
596 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
597 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
598 or not the superblock should be written out for the block
601 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
602 for sparse duplicate superblocks.
604 * version.c (ext2fs_get_library_version): New function which
605 returns the library version.
607 * version.c (ext2fs_parse_version_string): New function which
608 parses a version string and returns a version number,
609 so application programs can compare version numbers as
612 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
614 * icount.c (ext2fs_create_icount): Change function so that it also
615 takes a new argument which contains a "hint" icount
616 structure. This "hint" icount allows the create function
617 to set up the sorted list in advance. This reduces
618 significantly the amount of data moving needed to insert
619 these inodes into the list later.
621 * icount.c (ext2fs_icount_validate): New function which validates
622 that the icount structure's rep invariant.
624 * icount.c (get_icount_el): Completely revamped implementation
625 to subsume put_icount_el(). Put_icount_el() used to
626 use an O(N) implementation to insert in the middle
627 of the icount list. It now uses a O(ln N) to search
628 for where the icount should be inserted, and then uses
629 a memcpy to move the list down (instead of a for loop).
631 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
632 ext2fs_icount_increment, ext2fs_icount_decrement): Check
633 to see if the inode is within bounds; if it isn't, return
636 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
637 when a bad inode number is passed to test_generic_bitmap
638 to be EXT2FS_TEST_ERROR instead of the wrong
641 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
643 * Release of E2fsprogs version 1.07
645 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
647 * Makefile.in (ELF_VERSION): Change version to be 2.2
649 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
651 * alloc.c (ext2fs_get_free_blocks): Change routine to use
652 ext2fs_fast_test_block_bitmap_range().
654 * bitops.h (ext2fs_fast_test_block_bitmap_range,
655 ext2fs_test_block_bitmap_range: New inline functions which
656 test to see whether a contiguous range of blocks is
659 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
661 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
662 use ext2fs_badblocks_* instead of badblocks_*
664 * bb_compat.c: New file which translates between old badblocks_*()
665 names to ext2fs_badblocks_*()
667 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
668 link.c (since e2fsck doesn't use ext2fs_unlink()).
670 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
671 bitmap resizing routine moved from bitmaps.c, since e2fsck
672 doesn't need to use this function.
674 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
675 since e2fsck only needs ext2fs_lookup.
677 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
679 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
680 already set; this is needed so that programs like dump
681 which use the inode scan functions will deal with
682 filesystems that have bad blocks in the inode table.
684 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
686 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
687 Moved to ext2fsP.h, since it doesn't need to be part of
688 the public interface.
690 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
692 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
694 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
695 directory block list abstraction. (Code moved from
698 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
699 to inode.c (since no one else should be peeking inside it!)
701 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
703 * openfs.c (ext2fs_open): Check the feature set in the ext2
704 superblock, and refuse to open filesystems if they contain
705 incompatible features. (Can be overriden with the
708 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
710 * block.c (ext2fs_block_iterate2): Added new function
711 ext2fs_block_iterate2 which changes the function
712 signature of the callback function to include the
713 referencing block and offset.
715 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
716 ext2fs_inode_scan_goto_blockgroup which allows an
717 application to jump to a particular block group while
720 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
722 * dirblock.c: Include string.h, since we use memcpy().
724 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
726 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
727 a long not an int; this doesn't matter on i386 machines,
728 but it does on Alpha's.
730 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
732 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
733 table pointer is NULL, then return an error indicating
734 that the inode table is missing.
735 (get_next_blockgroup, get_next_blocks,
736 ext2fs_get_next_inode): Don't treat a missing inode table
737 as permanent error. Return MISSING_INODE_TABLE, but as an
738 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
740 * rw_bitmaps.c (ext2fs_write_block_bitmap,
741 ext2fs_write_inode_bitmap): If the inode or block bitmap
742 block is zero, then don't write out the inode or block
743 bitmap. The idea here is to avoid stomping on the
745 (read_bitmaps): If the inode or block bitmap block is
746 zero, then fill in that portion of the inode or block
747 bitmap with all zeros.
749 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
750 blocks in inode table when the inode table size is
751 non-standard (and can therefore span blocks).
753 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
755 * alloc.c (ext2fs_new_block): Fix fencepost error in
756 ext2fs_new_block; make sure we don't try to allocate the
757 first block beyond the end of the filesystem.
759 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
761 * inode.c (check_for_inode_bad_blocks): New function called by
762 get_next_blocks() to avoid reading in bad blocks marked in
763 fs->badblocks. Inodes located in bad blocks are returned
764 by ext2fs_get_next_inode() returns the error code
765 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
767 * alloc_tables.c (ext2fs_allocate_tables): New function which
768 performs the part of mke2fs's job of allocating the
771 * test_io.c (test_close): IO manager which is used for testing
774 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
776 * inode.c (ext2fs_get_next_inode): Separate out the function of
777 setting up for a new block group to get_next_blockgroup().
778 Separate out the function of reading in blocks of the
779 inode table to get_next_blocks().
781 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
783 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
784 blocks to the badblock list in sorted order. This allows
785 badblocks_list_test to be coded using a binary search for
788 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
790 * Release of E2fsprogs version 1.06
792 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
794 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
795 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
798 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
799 set, then only write out the master superblock.
801 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
803 * block.c (ext2fs_block_iterate): Fixed bug which caused
804 block_iterate to fail to handle HURD created filesystems;
805 it tested the inode translator field before the inode was
808 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
810 * initialize.c (ext2fs_initialize): Make sure the description for
811 the inode bitmap is set correctly.

819 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
821 * initialize.c: Override the kernel's idea of default
822 checkinterval from 0 (never) to 180 days.
824 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
826 * namei.c (ext2fs_namei_follow): New function which follows
827 symbolic link (if any) at the target.

839 * namei.c (ext2fs_follow_link): New function.
840 (ext2fs_namei): Extended to have support for chasing
841 symbolic links. ext2fs_namei() still returns an inode
842 which is a symbolic link. Symbolic links are only chased
843 while resolving the containing directory. To chase
844 symbolic links of the final result, use
845 ext2fs_follow_link().
847 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
849 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
851 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
852 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
854 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
856 * initialize.c (ext2fs_initialize): On systems where the byte
857 order is not i386 compatible, set the swap_byte flag.
859 * inode.c (inocpy_with_swap): Check to see if inode contains a
860 fast symlink before swapping the inode block fields. This
861 required adding a new argument to inocpy_with_swap to
862 determine whether the mode field is in host order or not.
864 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
866 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
867 the sparc, if EXT2_STD_BITOPS set, use the standard
868 i386-compatible bitmask operations, instead on the
869 non-standard native bitmask operators.
871 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
873 * block.c (ext2fs_block_iterate): Cause block iterator to return
874 the HURD translator block (along with everything else).
875 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
876 iterator, then don't return any meta data blocks
877 (including the HURD translator).
879 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
881 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
883 * uuid.c: New file, containing UUID utility functions.
885 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
887 * ext2fs.h: Add a definition of the "real" ext2 superblock.
889 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
891 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
893 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
895 * openfs.c (ext2fs_open): If the blocksize in the superblock is
896 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
897 that's a basic value that must be correct for the rest of
900 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
903 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
905 * Release of E2fsprogs version 1.04

914 Change the m68k bit numbering for bitmasks to match with
915 the bit numbering used by all other ext2 implementations.
917 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
919 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

953 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
954 to avoid conflicts with with kernel include files. Also
955 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
958 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
960 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
962 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around

969 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
971 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()

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

1000 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1002 * getsize.c (ext2fs_get_device_size): New function that determins
1003 the size of a device. Used by mke2fs and e2fsck.
1005 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1007 * Makefile.in (install): Install static libraries in $(ulibdir)

1012 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1013 Move these functions to freefs.c.
1015 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1016 descriptors shadow memory to keep purify quiet. (This
1017 also has the nice benefit that the unused portion of the
1018 shadow descriptors are zeroed out.)
1020 * dirblock.c (ext2fs_write_dir_block): We need to use
1021 dirent->rec_len *before* it's byteswapped to find the
1022 location of the next directory structure!
1024 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1025 cause ext2fs_new_inode to loop infinitely if we're trying
1026 to allocate an inode in group #0 and there are no free
1027 inodes at all in the system.
1029 * closefs.c: #include <errno.h> if it exists.
1031 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1033 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1055 EXT2_SWAP_BYTES is set (and swap them back before writing
1058 * inode.c (inocpy_with_swap): New function.
1059 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1060 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1062 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1063 the superblock and group descriptors before writing it out.
1065 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1066 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1067 and group descriptors.
1069 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1070 to desp ext2 filesystem structures.
1072 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1073 supplied by Pete A. Zaitcev so that the C language
1074 versions of these functions are more portable. They will
1075 now work on both little and big endian systems, and the
1076 assumption that 32-bit integers are used is gone.
1078 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1079 doing byte swapping.
1081 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1082 byte swapping should take place.
1084 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1086 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,

1088 containing routines to compare bitmaps.
1090 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1091 Added new error codes.
1093 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1095 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1096 if the magic number is correct, it will be allocated.
1098 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1100 * block.c (block_iterate_ind, block_iterate_dind,
1101 block_iterate_tind): Don't recompute block_nr each loop;
1102 just increment it! Factor check of BLOCK_FLAG_APPEND out
1103 of the loop. Factor mask of BLOCK_CHANGED into changed
1104 variable out of the loop. (block_iterate_ind, in
1105 particular, gets called a lot, so every little
1106 optimization helps.)
1108 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1110 * block.c (block_iterate_ind, block_iterate_dind,
1111 block_iterate_tind): Precompute limit of loop to speed up
1112 block_iterate_ind and company.
1114 * bitops.h (ext2fs_fast_mark_block_bitmap,
1115 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1116 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1117 ext2fs_fast_test_inode_bitmap): Add fast version of these
1118 functions, which don't do range checking.
1120 * bitops.h (ext2fs_get_block_bitmap_start,
1121 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1122 ext2fs_get_inode_bitmap_end): Add new accessor functions
1123 which return the start and end points of the bitmaps.
1125 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1127 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1128 instead of llseek. The errno if the offset is too large
1129 and lseek is not supported should be EINVAL, not -EINVAL.
1131 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1133 * Makefile.in: Added support for ELF shared libraries.
1134 Fixed typos in the compilation rules.
1135 (distclean): Added Makefile.
1137 * llseek.c (llseek): New function, if llseek() does not exist in the
1139 (ext2_llseek): Changed to call llseek().
1141 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1143 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1145 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1147 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1149 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1150 the S_*, which are normally defined in <sys/stat.h>. This
1151 allows us to compile e2fsprogs on a non-Linux system,
1152 which may have a different value for S_IFDIR.
1154 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1156 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1157 this is a user-mode application!
1159 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1161 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1162 __linux__ so that non-linux systems won't see it.
1164 * alloc.c: Include <errno.h> if possible.
1165 * badblocks.c: Ditto.
1166 * bb_inode.c: Ditto.
1169 * expanddir.c: Ditto.
1170 * get_pathname.c: Ditto.
1171 * initialize.c: Ditto.
1178 * rw_bitmaps.c: Ditto.
1181 * Makefile.in: Rewritten to conform to GNU coding standards and
1182 support separate compilation directories.
1184 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1186 * initialize.c (ext2fs_initialize): Don't allow more than one
1187 bitmaps's worth of inodes in a group.
1189 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1191 * llseek.c (ext2_llseek): Added error checking to the llseek()
1192 compat code to protect against overflow. This only
1193 applies to 1.0 and early 1.1 kernels, which don't support
1194 the llseek() system call.
1196 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1198 * unix_io.c (unix_open): Initialize the read_error and write_error
1199 io_channel pointers to be null.
1201 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1202 found, clear it but don't try to update the filesystem
1203 accounting information, since that's hopeless anyway.
1205 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1206 bloblock_iterate_tind): Check to see if the indirect blocks are
1207 valid before trying to read them.

1210 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1212 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1213 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1214 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1215 illegal block or inode number is passed in, return instead
1216 of trying to test, set, or clear the bit.
1218 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1220 * Makefile: Added a dummy install target in case shared libraries
1223 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1225 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1226 the real last block of the bitmap should be calculated.

1230 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1231 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1232 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1233 ext2fs_free_block_bitmap): Add magic number checking for
1234 the inode and block bitmaps.
1236 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1237 magic number for a block bitmap instead of an inode bitmap.
1239 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1240 magic number checking for the inode_scan structure.
1242 * badblocks.c (badblocks_list_free, badblocks_list_add,
1243 badblocks_list_test, badblocks_list_iterate_begin,
1244 badblocks_list_iterate, badblocks_list_iterate_end): Add
1245 magic number checking for the badblocks_list and
1246 badblocks_iterate structures.
1248 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1249 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1250 unix_write_blk, unix_flush): Add magic number checking
1251 both for io_channel structure and unix_private_data
1254 * openfs.c (ext2fs_open): Add check for io_manager structure's
1257 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1258 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1259 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1260 * read_bb.c (ext2fs_read_bb_inode):
1261 * read_bb_file.c (ext2fs_read_bb_FILE):
1262 * newdir.c (ext2fs_new_dir_block):

1272 ext2fs_allocate_block_bitmap):
1273 * bb_inode.c (ext2fs_update_bb_inode):
1274 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1275 * check_desc.c (ext2fs_check_desc):
1276 * closefs.c (ext2fs_close, ext2fs_flush):
1277 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1282 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1283 openfs.c into its own file.
1285 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1286 structure magic numbers.
1288 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1289 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1290 someone uses the -b option to specify the use of the backup
1291 superblock --- this usually means that the main superblock is
1295 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1296 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1297 revision level to the superblock.
1299 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1306 * initialize.c: Completely revamped the inode and block bitmap
1307 structures, so that they can be better chance of being extensible
1308 in a shared library. They are now their own type, instead of
1309 being a char *. Also, the function signatures of
1310 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1311 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1312 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1313 changed to eliminate the ext2_filsys argument, since it is no
1316 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1318 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1319 system call if available.
1321 * llseek.c: new file. This is the stub calling the llseek system
1322 call which allows supports for 2GB+ file systems.
1324 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1325 the creator operating system.
1327 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1329 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1330 the group descriptor statistics in addition to everything else.
1331 This relieves mke2fs of the responsibility of doing it.
1333 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1334 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1335 not the generic C function equivalents should be included or not.
1337 * openfs.c (ext2fs_open): If a superblock is specified, then use
1338 the backup group descriptors that go along with this superblock,
1339 instead of using the primary group descriptors. This allows
1340 e2fsck to recover filesystems where the primary group descriptors
