1 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
3 * inode.c (get_next_blockgroup): Fix bug where if
4 get_next_blockgroup() is called early because of a missing
5 inode table in a block group, the current_inode counter
6 wasn't incremented correctly.
8 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
10 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
11 against a completely trashed bad block inode.
13 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
15 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
16 the stride length hits a bad value, we retry the block
17 allocation starting at the beginning of the block group.
19 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
20 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
21 e2_blkcnt_t to avoid collision with LFS API.
23 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
25 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
26 way that avoids overflows on disk sizes greater than 4GB.
28 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
30 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
31 return type for comparison functions for qsort.
33 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
36 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
38 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
41 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
42 evade a potential problem with glibc's header files trying
43 to spike out linux/types.h.
45 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
46 include the old size of the memory, which is needed for
47 some braindamaged memory allocation systems that don't

62 convention. Fix uninstall rules to take $(DESTDIR) into
65 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
67 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
68 with 32 bit longs, then we need to manually define __s64
69 and __u64, since the current kernel header files don't
70 define these if __STRICT_ANSI__ is defined. This is a
71 problem if we are compiling with full GCC warnings, since
72 we do need 64 bit support.
74 * Makefile.in (OBJS): Remove bmove.o from files to be built,
75 since we're not using ext2fs_move_blocks() and there
76 is some question as to its usefulness in its current
79 * bmap.c (block_bmap): Remove unused function.
81 * bmove.c (process_block): Fix -Wall warning.
83 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
85 * block.c (ext2fs_block_iterate3): Make the ref_offset field
86 contain the offset into the inode.i_blocks array when
87 ref_block is zero. Since we haven't done a formal
88 release of e2fsprogs since block_iterate2 was first
89 introduced, I removed block_iterate2, and renamed
90 block_iterate3 to be block_iterate2.
92 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
93 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
94 use of block_iterate and block_iterate2 to
95 block_iterate2 with the new prototype for the
96 interator function. (using blkcnt_t forr blockcount)
98 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
100 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
101 s_prealloc_blocks, s_prealloc_dir_blocks). Added
102 conditional defines of new features COMPAT_DIR_PREALLOC,
103 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
104 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
105 the library to declare that we support COMPAT_DIR_PREALLOC,
106 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
108 * fileio.c: Rename function ext2fs_file_llseek to be
109 ext2fs_file_lseek, which is more accurate.
111 * block.c: Add new function ext2fs_block_iterate3 which calls
112 the iterator function with the blockcount argument of
113 type blkcnt_t. This version of the function is
114 allowed to handle large files; the other fucntions are
117 * ext2fs.h: Add new type blkcnt_t
119 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
121 * block.c (ext2fs_block_iterate2): Fix bug where the block count
122 field wasn't getting correctly incremented for sparse
123 files when the indirect or doubly-indirect block
124 specified in the inode was zero.
126 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
128 * unlink.c (unlink_proc):
129 * lookup.c (lookup_proc):
130 * link.c (link_proc):
131 * get_pathname.c (get_pathname_proc):
132 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
133 from dirent->name_len, so it can be used for other
136 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
137 and indicate that we have support for this incompatible
140 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
142 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

146 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
147 number of directories when the block group information is
150 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
152 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
153 inode table is missing so that we catch the case where the
154 first block group is missing.
156 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
159 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
161 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
163 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
165 * test_io.c (test_flush): Add a debugging printf when the flush
168 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
169 read in, return right away.
171 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
173 * bitops.h: Don't try to do i386 inline asm functions if the
176 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
177 instead of linux/types.h, and e2_bitops.h instead of
180 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
183 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
185 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
186 so that we don't need to call get_next_blockgroup() the
187 first time around. Saves a bit of time, and prevents us
188 from needing to assign -1 to current_group (which is an
191 * icount.c (insert_icount_el): Cast the estimated number of inodes
192 from a float to an ino_t.

204 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
205 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
206 defined, then assume all of the
207 ext2-specific header files are in a flat directory.
209 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
210 all assignments from void * to be compatible with C++.

231 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
233 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
234 paranoid about validating the directory counts from the
235 block group information.
237 * all files: Don't include stdlib.h anymore; include it in
238 ext2_fs.h, since that file requires stdlib.h
240 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
242 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
243 bitmap is loaded, and return an error if it is not.
244 (expand_dir_proc): Only use ext2fs_write_dir_block when
245 writing a directory block, not when writing out a fresh
248 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

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

296 * fileio.c: New file which implements simple file reading and
299 * alloc.c (ext2fs_alloc_block): New function which allocates a
300 block, zeros it, and updates the filesystem accounting
301 records appropriately.

315 need to declare llseek().
317 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
319 * Rename io.h to be ext2_io.h (avoid namespace collisions)

362 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
363 to make life easer for GNU Libc 2.
365 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
366 filesystem has its bitmaps stored as 32-bit words with bit
367 0 as the LSB of each word. Thus a bitmap with only bit 0
368 set would be, as a string of bytes, 00 00 00 01 00 ... To
369 cope with this, we byte-reverse each word of a bitmap if
370 we have a big-endian filesystem, that is, if we are *not*
371 byte-swapping other word-sized numbers.

491 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
492 ext2fs_badblocks_list_test would test the list (and exceed
493 array boundaries) if there were no bad blocks on the bad
494 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
496 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
498 * Release of E2fsprogs version 1.10

530 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
531 free if refcount goes to zero.
533 * inode.c (create_icache): Initialize refcount to 1.
535 * ext2fsP.h: Added refcount to ext2_inode_cache
537 * dblist.c (ext2fs_copy_dblist): New function to copy a directory

547 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
549 (unix_close, test_close): Decrement the refcount and only
550 close the io_channel if the refcount goes to 0.
552 * io.h: Add refcount to the io_channel structure. Add new macro
553 interface io_channel_bumpcount() to bump the refcount.
555 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
557 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
558 cache in the filesystem handle, instead of the inode cache
559 in a static variable.
561 * freefs.c: Added static function to free the inode cache (called by
564 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
566 * ext2fs.h: Added pointer to the inode_cache structure.
568 * block.c (block_iterate_ind, block_iterate_dind,
569 block_iterate_tind): If there are holes in the indirect,
570 doubly indirect, or triply indirect blocks, increment the
571 block count field automatically.
573 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
575 * Release of E2fsprogs version 1.09
577 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
579 * version.c (ext2fs_parse_version_string): Check the passed in
580 version string (instead of the hard-coded one).
582 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
583 greater filesystem size, clamp it to prevent allocating a
584 block or inode bitmap beyond the filesystem.
586 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
587 overhead calculation was accidentally removed.
589 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
591 * Release of E2fsprogs version 1.08
593 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
595 * dblist.c (ext2fs_set_dir_block): New function which sets the
596 block of a dblist entry, given the directory inode and
599 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
601 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
602 inode bitmaps at staggered locations across the block
603 groups, to avoid concentrating the bitmaps on a small
604 number of disks when using striped RAID arrays.
606 * initialize.c (ext2fs_initialize): By default, choose the maximum
607 possible number of blocks per group (based on the size of
608 the bitmaps in the blocksize).
610 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
612 * initialize.c (ext2fs_initialize): Add support for
613 EXT2_COMPAT_SPARSE_SUPER feature.
615 * closefs.c (ext2fs_bg_has_super): New function to determine
616 whether or a particular block group should have a
617 superblock and block group descriptor. Used for the
618 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
619 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
620 or not the superblock should be written out for the block
623 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
624 for sparse duplicate superblocks.
626 * version.c (ext2fs_get_library_version): New function which
627 returns the library version.
629 * version.c (ext2fs_parse_version_string): New function which
630 parses a version string and returns a version number,
631 so application programs can compare version numbers as
634 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
636 * icount.c (ext2fs_create_icount): Change function so that it also
637 takes a new argument which contains a "hint" icount
638 structure. This "hint" icount allows the create function
639 to set up the sorted list in advance. This reduces
640 significantly the amount of data moving needed to insert
641 these inodes into the list later.
643 * icount.c (ext2fs_icount_validate): New function which validates
644 that the icount structure's rep invariant.
646 * icount.c (get_icount_el): Completely revamped implementation
647 to subsume put_icount_el(). Put_icount_el() used to
648 use an O(N) implementation to insert in the middle
649 of the icount list. It now uses a O(ln N) to search
650 for where the icount should be inserted, and then uses
651 a memcpy to move the list down (instead of a for loop).
653 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
654 ext2fs_icount_increment, ext2fs_icount_decrement): Check
655 to see if the inode is within bounds; if it isn't, return
658 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
659 when a bad inode number is passed to test_generic_bitmap
660 to be EXT2FS_TEST_ERROR instead of the wrong
663 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
665 * Release of E2fsprogs version 1.07
667 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
669 * Makefile.in (ELF_VERSION): Change version to be 2.2
671 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
673 * alloc.c (ext2fs_get_free_blocks): Change routine to use
674 ext2fs_fast_test_block_bitmap_range().
676 * bitops.h (ext2fs_fast_test_block_bitmap_range,
677 ext2fs_test_block_bitmap_range: New inline functions which
678 test to see whether a contiguous range of blocks is
681 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
683 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
684 use ext2fs_badblocks_* instead of badblocks_*
686 * bb_compat.c: New file which translates between old badblocks_*()
687 names to ext2fs_badblocks_*()
689 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
690 link.c (since e2fsck doesn't use ext2fs_unlink()).
692 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
693 bitmap resizing routine moved from bitmaps.c, since e2fsck
694 doesn't need to use this function.
696 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
697 since e2fsck only needs ext2fs_lookup.
699 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
701 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
702 already set; this is needed so that programs like dump
703 which use the inode scan functions will deal with
704 filesystems that have bad blocks in the inode table.
706 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
708 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
709 Moved to ext2fsP.h, since it doesn't need to be part of
710 the public interface.
712 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
714 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
716 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
717 directory block list abstraction. (Code moved from
720 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
721 to inode.c (since no one else should be peeking inside it!)
723 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
725 * openfs.c (ext2fs_open): Check the feature set in the ext2
726 superblock, and refuse to open filesystems if they contain
727 incompatible features. (Can be overriden with the
730 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
732 * block.c (ext2fs_block_iterate2): Added new function
733 ext2fs_block_iterate2 which changes the function
734 signature of the callback function to include the
735 referencing block and offset.
737 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
738 ext2fs_inode_scan_goto_blockgroup which allows an
739 application to jump to a particular block group while
742 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
744 * dirblock.c: Include string.h, since we use memcpy().
746 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
748 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
749 a long not an int; this doesn't matter on i386 machines,
750 but it does on Alpha's.
752 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
754 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
755 table pointer is NULL, then return an error indicating
756 that the inode table is missing.
757 (get_next_blockgroup, get_next_blocks,
758 ext2fs_get_next_inode): Don't treat a missing inode table
759 as permanent error. Return MISSING_INODE_TABLE, but as an
760 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
762 * rw_bitmaps.c (ext2fs_write_block_bitmap,
763 ext2fs_write_inode_bitmap): If the inode or block bitmap
764 block is zero, then don't write out the inode or block
765 bitmap. The idea here is to avoid stomping on the
767 (read_bitmaps): If the inode or block bitmap block is
768 zero, then fill in that portion of the inode or block
769 bitmap with all zeros.
771 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
772 blocks in inode table when the inode table size is
773 non-standard (and can therefore span blocks).
775 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
777 * alloc.c (ext2fs_new_block): Fix fencepost error in
778 ext2fs_new_block; make sure we don't try to allocate the
779 first block beyond the end of the filesystem.
781 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
783 * inode.c (check_for_inode_bad_blocks): New function called by
784 get_next_blocks() to avoid reading in bad blocks marked in
785 fs->badblocks. Inodes located in bad blocks are returned
786 by ext2fs_get_next_inode() returns the error code
787 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
789 * alloc_tables.c (ext2fs_allocate_tables): New function which
790 performs the part of mke2fs's job of allocating the
793 * test_io.c (test_close): IO manager which is used for testing
796 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
798 * inode.c (ext2fs_get_next_inode): Separate out the function of
799 setting up for a new block group to get_next_blockgroup().
800 Separate out the function of reading in blocks of the
801 inode table to get_next_blocks().
803 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
805 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
806 blocks to the badblock list in sorted order. This allows
807 badblocks_list_test to be coded using a binary search for
810 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
812 * Release of E2fsprogs version 1.06
814 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
816 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
817 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
820 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
821 set, then only write out the master superblock.
823 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
825 * block.c (ext2fs_block_iterate): Fixed bug which caused
826 block_iterate to fail to handle HURD created filesystems;
827 it tested the inode translator field before the inode was
830 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
832 * initialize.c (ext2fs_initialize): Make sure the description for
833 the inode bitmap is set correctly.
835 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

843 * initialize.c: Override the kernel's idea of default
844 checkinterval from 0 (never) to 180 days.
846 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
848 * namei.c (ext2fs_namei_follow): New function which follows
849 symbolic link (if any) at the target.
851 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
853 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
854 for shortcut function fs->read_inode() and fs->write_inode().

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

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

975 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
976 to avoid conflicts with with kernel include files. Also
977 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
980 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
982 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
984 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
985 s_def_resuid and s_def_resgid for backwards compatibility.
987 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

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

1002 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1005 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>

1008 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1010 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1012 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
1014 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of

1019 * getsize.c (ext2fs_get_device_size): Add support for reading the
1020 partition size from a BSD disk label.
1022 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1024 * getsize.c (ext2fs_get_device_size): New function that determins
1025 the size of a device. Used by mke2fs and e2fsck.
1027 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1029 * Makefile.in (install): Install static libraries in $(ulibdir)
1030 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
1032 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
1034 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1035 Move these functions to freefs.c.
1037 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1038 descriptors shadow memory to keep purify quiet. (This
1039 also has the nice benefit that the unused portion of the
1040 shadow descriptors are zeroed out.)
1042 * dirblock.c (ext2fs_write_dir_block): We need to use
1043 dirent->rec_len *before* it's byteswapped to find the
1044 location of the next directory structure!
1046 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1047 cause ext2fs_new_inode to loop infinitely if we're trying
1048 to allocate an inode in group #0 and there are no free
1049 inodes at all in the system.
1051 * closefs.c: #include <errno.h> if it exists.
1053 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1055 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1061 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1062 installation directories correctly.
1064 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1066 * namei.c (process_dir_block):
1067 * mkdir.c (ext2fs_mkdir):
1068 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1069 to read/write the directory block.
1071 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1072 file containing functions for reading and writing
1073 directory blocks (byte swapping if necesssary)
1075 * block.c (block_iterate_ind, block_iterate_dind,
1076 block_iterate_tind): Byte swap the block addresses if
1077 EXT2_SWAP_BYTES is set (and swap them back before writing
1080 * inode.c (inocpy_with_swap): New function.
1081 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1082 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1084 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1085 the superblock and group descriptors before writing it out.
1087 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1088 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1089 and group descriptors.
1091 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1092 to desp ext2 filesystem structures.
1094 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1095 supplied by Pete A. Zaitcev so that the C language
1096 versions of these functions are more portable. They will
1097 now work on both little and big endian systems, and the
1098 assumption that 32-bit integers are used is gone.
1100 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1101 doing byte swapping.
1103 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1104 byte swapping should take place.
1106 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1108 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,

1113 Added new error codes.
1115 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1117 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1118 if the magic number is correct, it will be allocated.
1120 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1122 * block.c (block_iterate_ind, block_iterate_dind,
1123 block_iterate_tind): Don't recompute block_nr each loop;
1124 just increment it! Factor check of BLOCK_FLAG_APPEND out
1125 of the loop. Factor mask of BLOCK_CHANGED into changed
1126 variable out of the loop. (block_iterate_ind, in
1127 particular, gets called a lot, so every little
1128 optimization helps.)
1130 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1132 * block.c (block_iterate_ind, block_iterate_dind,
1133 block_iterate_tind): Precompute limit of loop to speed up
1134 block_iterate_ind and company.
1136 * bitops.h (ext2fs_fast_mark_block_bitmap,
1137 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1138 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1139 ext2fs_fast_test_inode_bitmap): Add fast version of these
1140 functions, which don't do range checking.
1142 * bitops.h (ext2fs_get_block_bitmap_start,
1143 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1144 ext2fs_get_inode_bitmap_end): Add new accessor functions
1145 which return the start and end points of the bitmaps.
1147 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1149 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1150 instead of llseek. The errno if the offset is too large
1151 and lseek is not supported should be EINVAL, not -EINVAL.
1153 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1155 * Makefile.in: Added support for ELF shared libraries.
1156 Fixed typos in the compilation rules.
1157 (distclean): Added Makefile.
1159 * llseek.c (llseek): New function, if llseek() does not exist in the
1161 (ext2_llseek): Changed to call llseek().
1163 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1165 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1167 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1169 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1171 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1172 the S_*, which are normally defined in <sys/stat.h>. This
1173 allows us to compile e2fsprogs on a non-Linux system,
1174 which may have a different value for S_IFDIR.
1176 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1178 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1179 this is a user-mode application!
1181 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1183 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1184 __linux__ so that non-linux systems won't see it.
1186 * alloc.c: Include <errno.h> if possible.
1187 * badblocks.c: Ditto.
1188 * bb_inode.c: Ditto.
1191 * expanddir.c: Ditto.
1192 * get_pathname.c: Ditto.
1193 * initialize.c: Ditto.
1200 * rw_bitmaps.c: Ditto.
1203 * Makefile.in: Rewritten to conform to GNU coding standards and
1204 support separate compilation directories.
1206 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1208 * initialize.c (ext2fs_initialize): Don't allow more than one
1209 bitmaps's worth of inodes in a group.
1211 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1213 * llseek.c (ext2_llseek): Added error checking to the llseek()
1214 compat code to protect against overflow. This only
1215 applies to 1.0 and early 1.1 kernels, which don't support
1216 the llseek() system call.
1218 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1220 * unix_io.c (unix_open): Initialize the read_error and write_error
1221 io_channel pointers to be null.
1223 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1224 found, clear it but don't try to update the filesystem
1225 accounting information, since that's hopeless anyway.
1227 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1228 bloblock_iterate_tind): Check to see if the indirect blocks are
1229 valid before trying to read them.
1231 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1232 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1234 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1235 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1236 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1237 illegal block or inode number is passed in, return instead
1238 of trying to test, set, or clear the bit.
1240 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1242 * Makefile: Added a dummy install target in case shared libraries
1245 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1247 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1248 the real last block of the bitmap should be calculated.

1252 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1253 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1254 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1255 ext2fs_free_block_bitmap): Add magic number checking for
1256 the inode and block bitmaps.
1258 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1259 magic number for a block bitmap instead of an inode bitmap.
1261 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1262 magic number checking for the inode_scan structure.
1264 * badblocks.c (badblocks_list_free, badblocks_list_add,
1265 badblocks_list_test, badblocks_list_iterate_begin,
1266 badblocks_list_iterate, badblocks_list_iterate_end): Add
1267 magic number checking for the badblocks_list and
1268 badblocks_iterate structures.
1270 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1271 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1272 unix_write_blk, unix_flush): Add magic number checking
1273 both for io_channel structure and unix_private_data
1276 * openfs.c (ext2fs_open): Add check for io_manager structure's
1279 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1280 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1281 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1282 * read_bb.c (ext2fs_read_bb_inode):
1283 * read_bb_file.c (ext2fs_read_bb_FILE):

1294 ext2fs_allocate_block_bitmap):
1295 * bb_inode.c (ext2fs_update_bb_inode):
1296 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):

1298 * closefs.c (ext2fs_close, ext2fs_flush):
1299 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1304 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1305 openfs.c into its own file.
1307 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1308 structure magic numbers.
1310 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1311 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1312 someone uses the -b option to specify the use of the backup
1313 superblock --- this usually means that the main superblock is
1317 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1318 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1319 revision level to the superblock.
1321 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1328 * initialize.c: Completely revamped the inode and block bitmap
1329 structures, so that they can be better chance of being extensible
1330 in a shared library. They are now their own type, instead of
1331 being a char *. Also, the function signatures of
1332 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1333 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1334 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1335 changed to eliminate the ext2_filsys argument, since it is no
1338 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1340 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1341 system call if available.
1343 * llseek.c: new file. This is the stub calling the llseek system
1344 call which allows supports for 2GB+ file systems.
1346 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1347 the creator operating system.
1349 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1351 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1352 the group descriptor statistics in addition to everything else.
1353 This relieves mke2fs of the responsibility of doing it.
1355 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1356 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1357 not the generic C function equivalents should be included or not.
1359 * openfs.c (ext2fs_open): If a superblock is specified, then use
1360 the backup group descriptors that go along with this superblock,
1361 instead of using the primary group descriptors. This allows
1362 e2fsck to recover filesystems where the primary group descriptors
