1 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
3 * Release of E2fsprogs 1.12
5 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
7 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
8 appropriate for all of the block group copies, so that
9 it's clear where the beginning of the filesystem is on the
10 disk. (For when the partition table gets scrod.)
12 * ext2fs.h: Change the name of the feature from
13 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
14 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
16 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
18 * inode.c (get_next_blockgroup): Fix bug where if
19 get_next_blockgroup() is called early because of a missing
20 inode table in a block group, the current_inode counter
21 wasn't incremented correctly.
23 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
25 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
26 against a completely trashed bad block inode.
28 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
30 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
31 the stride length hits a bad value, we retry the block
32 allocation starting at the beginning of the block group.
34 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
35 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
36 e2_blkcnt_t to avoid collision with LFS API.
38 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
40 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
41 way that avoids overflows on disk sizes greater than 4GB.
43 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
45 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
46 return type for comparison functions for qsort.
48 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
51 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
53 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
56 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
57 evade a potential problem with glibc's header files trying
58 to spike out linux/types.h.
60 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
61 include the old size of the memory, which is needed for
62 some braindamaged memory allocation systems that don't
65 * badblocks.c (ext2fs_badblocks_list_add):
66 bb_inode.c (clear_bad_block_proc):
67 dblist.c (ext2fs_add_dir_block):

77 convention. Fix uninstall rules to take $(DESTDIR) into
80 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
82 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
83 with 32 bit longs, then we need to manually define __s64
84 and __u64, since the current kernel header files don't
85 define these if __STRICT_ANSI__ is defined. This is a
86 problem if we are compiling with full GCC warnings, since
87 we do need 64 bit support.
89 * Makefile.in (OBJS): Remove bmove.o from files to be built,
90 since we're not using ext2fs_move_blocks() and there
91 is some question as to its usefulness in its current
94 * bmap.c (block_bmap): Remove unused function.
96 * bmove.c (process_block): Fix -Wall warning.
98 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
100 * block.c (ext2fs_block_iterate3): Make the ref_offset field
101 contain the offset into the inode.i_blocks array when
102 ref_block is zero. Since we haven't done a formal
103 release of e2fsprogs since block_iterate2 was first
104 introduced, I removed block_iterate2, and renamed
105 block_iterate3 to be block_iterate2.
107 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
108 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
109 use of block_iterate and block_iterate2 to
110 block_iterate2 with the new prototype for the
111 interator function. (using blkcnt_t forr blockcount)
113 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
115 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
116 s_prealloc_blocks, s_prealloc_dir_blocks). Added
117 conditional defines of new features COMPAT_DIR_PREALLOC,
118 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
119 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
120 the library to declare that we support COMPAT_DIR_PREALLOC,
121 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
123 * fileio.c: Rename function ext2fs_file_llseek to be
124 ext2fs_file_lseek, which is more accurate.
126 * block.c: Add new function ext2fs_block_iterate3 which calls
127 the iterator function with the blockcount argument of
128 type blkcnt_t. This version of the function is
129 allowed to handle large files; the other fucntions are
132 * ext2fs.h: Add new type blkcnt_t
134 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
136 * block.c (ext2fs_block_iterate2): Fix bug where the block count
137 field wasn't getting correctly incremented for sparse
138 files when the indirect or doubly-indirect block
139 specified in the inode was zero.
141 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
143 * unlink.c (unlink_proc):
144 * lookup.c (lookup_proc):
145 * link.c (link_proc):
146 * get_pathname.c (get_pathname_proc):
147 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
148 from dirent->name_len, so it can be used for other
151 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
152 and indicate that we have support for this incompatible
155 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
157 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

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

219 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
220 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
221 defined, then assume all of the
222 ext2-specific header files are in a flat directory.
224 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
225 all assignments from void * to be compatible with C++.

241 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
242 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
243 unlink.c: Change private to be priv_data (to avoid C++
246 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
248 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
249 paranoid about validating the directory counts from the
250 block group information.
252 * all files: Don't include stdlib.h anymore; include it in
253 ext2_fs.h, since that file requires stdlib.h
255 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
257 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
258 bitmap is loaded, and return an error if it is not.
259 (expand_dir_proc): Only use ext2fs_write_dir_block when
260 writing a directory block, not when writing out a fresh
263 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

287 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
289 * [all files, basically]: Added definition of ext2fs_get_mem,
290 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
291 changed all library routines to use these wrapper functions.
293 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
294 instead of the system error messages.

311 * fileio.c: New file which implements simple file reading and
314 * alloc.c (ext2fs_alloc_block): New function which allocates a
315 block, zeros it, and updates the filesystem accounting
316 records appropriately.
318 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
320 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,

329 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
330 need to declare llseek().
332 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
334 * Rename io.h to be ext2_io.h (avoid namespace collisions)
336 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H

362 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
364 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
365 added a new field to the io_channel (app_data).
367 * io.h: Add a new element to the io_channel structure, app_data.

377 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
378 to make life easer for GNU Libc 2.
380 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
381 filesystem has its bitmaps stored as 32-bit words with bit
382 0 as the LSB of each word. Thus a bitmap with only bit 0
383 set would be, as a string of bytes, 00 00 00 01 00 ... To
384 cope with this, we byte-reverse each word of a bitmap if
385 we have a big-endian filesystem, that is, if we are *not*
386 byte-swapping other word-sized numbers.

467 the number of directory blocks in dblist.
469 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
471 * unix_io.c (unix_flush): Make the io_channel flush function do a
472 fsync to flush the kernel buffers to disk.
474 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
476 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the

480 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
482 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
483 of blocks which need to be moved, and moves those blocks
484 to another location in the filesystem.

487 bitmap, make sure all of the new parts of the bitmap are
490 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

506 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
507 ext2fs_badblocks_list_test would test the list (and exceed
508 array boundaries) if there were no bad blocks on the bad
509 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
511 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
513 * Release of E2fsprogs version 1.10
515 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
517 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
518 inode and block bitmaps based on the RAID 0 stride
519 parameter (which is passed by mke2fs).
521 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
522 mke2fs to communicate the stride length to

539 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
540 filesystem has no free blocks, ext2fs_new_block would loop
543 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
545 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only

562 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
564 (unix_close, test_close): Decrement the refcount and only
565 close the io_channel if the refcount goes to 0.
567 * io.h: Add refcount to the io_channel structure. Add new macro
568 interface io_channel_bumpcount() to bump the refcount.
570 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
572 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
573 cache in the filesystem handle, instead of the inode cache
574 in a static variable.
576 * freefs.c: Added static function to free the inode cache (called by
579 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
581 * ext2fs.h: Added pointer to the inode_cache structure.
583 * block.c (block_iterate_ind, block_iterate_dind,
584 block_iterate_tind): If there are holes in the indirect,
585 doubly indirect, or triply indirect blocks, increment the
586 block count field automatically.
588 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
590 * Release of E2fsprogs version 1.09
592 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
594 * version.c (ext2fs_parse_version_string): Check the passed in
595 version string (instead of the hard-coded one).
597 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
598 greater filesystem size, clamp it to prevent allocating a
599 block or inode bitmap beyond the filesystem.
601 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
602 overhead calculation was accidentally removed.
604 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
606 * Release of E2fsprogs version 1.08
608 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
610 * dblist.c (ext2fs_set_dir_block): New function which sets the
611 block of a dblist entry, given the directory inode and
614 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
616 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
617 inode bitmaps at staggered locations across the block
618 groups, to avoid concentrating the bitmaps on a small
619 number of disks when using striped RAID arrays.
621 * initialize.c (ext2fs_initialize): By default, choose the maximum
622 possible number of blocks per group (based on the size of
623 the bitmaps in the blocksize).
625 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
627 * initialize.c (ext2fs_initialize): Add support for
628 EXT2_COMPAT_SPARSE_SUPER feature.
630 * closefs.c (ext2fs_bg_has_super): New function to determine
631 whether or a particular block group should have a
632 superblock and block group descriptor. Used for the
633 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
634 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
635 or not the superblock should be written out for the block
638 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
639 for sparse duplicate superblocks.
641 * version.c (ext2fs_get_library_version): New function which
642 returns the library version.
644 * version.c (ext2fs_parse_version_string): New function which
645 parses a version string and returns a version number,
646 so application programs can compare version numbers as
649 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
651 * icount.c (ext2fs_create_icount): Change function so that it also
652 takes a new argument which contains a "hint" icount
653 structure. This "hint" icount allows the create function
654 to set up the sorted list in advance. This reduces
655 significantly the amount of data moving needed to insert
656 these inodes into the list later.
658 * icount.c (ext2fs_icount_validate): New function which validates
659 that the icount structure's rep invariant.
661 * icount.c (get_icount_el): Completely revamped implementation
662 to subsume put_icount_el(). Put_icount_el() used to
663 use an O(N) implementation to insert in the middle
664 of the icount list. It now uses a O(ln N) to search
665 for where the icount should be inserted, and then uses
666 a memcpy to move the list down (instead of a for loop).
668 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
669 ext2fs_icount_increment, ext2fs_icount_decrement): Check
670 to see if the inode is within bounds; if it isn't, return
673 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
674 when a bad inode number is passed to test_generic_bitmap
675 to be EXT2FS_TEST_ERROR instead of the wrong
678 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
680 * Release of E2fsprogs version 1.07
682 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
684 * Makefile.in (ELF_VERSION): Change version to be 2.2
686 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
688 * alloc.c (ext2fs_get_free_blocks): Change routine to use
689 ext2fs_fast_test_block_bitmap_range().
691 * bitops.h (ext2fs_fast_test_block_bitmap_range,
692 ext2fs_test_block_bitmap_range: New inline functions which
693 test to see whether a contiguous range of blocks is
696 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
698 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
699 use ext2fs_badblocks_* instead of badblocks_*
701 * bb_compat.c: New file which translates between old badblocks_*()
702 names to ext2fs_badblocks_*()
704 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
705 link.c (since e2fsck doesn't use ext2fs_unlink()).
707 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
708 bitmap resizing routine moved from bitmaps.c, since e2fsck
709 doesn't need to use this function.
711 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
712 since e2fsck only needs ext2fs_lookup.
714 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
716 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
717 already set; this is needed so that programs like dump
718 which use the inode scan functions will deal with
719 filesystems that have bad blocks in the inode table.
721 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
723 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
724 Moved to ext2fsP.h, since it doesn't need to be part of
725 the public interface.
727 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
729 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
731 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
732 directory block list abstraction. (Code moved from
735 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
736 to inode.c (since no one else should be peeking inside it!)
738 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
740 * openfs.c (ext2fs_open): Check the feature set in the ext2
741 superblock, and refuse to open filesystems if they contain
742 incompatible features. (Can be overriden with the
745 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
747 * block.c (ext2fs_block_iterate2): Added new function
748 ext2fs_block_iterate2 which changes the function
749 signature of the callback function to include the
750 referencing block and offset.
752 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
753 ext2fs_inode_scan_goto_blockgroup which allows an
754 application to jump to a particular block group while
757 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
759 * dirblock.c: Include string.h, since we use memcpy().
761 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
763 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
764 a long not an int; this doesn't matter on i386 machines,
765 but it does on Alpha's.
767 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
769 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
770 table pointer is NULL, then return an error indicating
771 that the inode table is missing.
772 (get_next_blockgroup, get_next_blocks,
773 ext2fs_get_next_inode): Don't treat a missing inode table
774 as permanent error. Return MISSING_INODE_TABLE, but as an
775 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
777 * rw_bitmaps.c (ext2fs_write_block_bitmap,
778 ext2fs_write_inode_bitmap): If the inode or block bitmap
779 block is zero, then don't write out the inode or block
780 bitmap. The idea here is to avoid stomping on the
782 (read_bitmaps): If the inode or block bitmap block is
783 zero, then fill in that portion of the inode or block
784 bitmap with all zeros.
786 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
787 blocks in inode table when the inode table size is
788 non-standard (and can therefore span blocks).
790 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
792 * alloc.c (ext2fs_new_block): Fix fencepost error in
793 ext2fs_new_block; make sure we don't try to allocate the
794 first block beyond the end of the filesystem.
796 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
798 * inode.c (check_for_inode_bad_blocks): New function called by
799 get_next_blocks() to avoid reading in bad blocks marked in
800 fs->badblocks. Inodes located in bad blocks are returned
801 by ext2fs_get_next_inode() returns the error code
802 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
804 * alloc_tables.c (ext2fs_allocate_tables): New function which
805 performs the part of mke2fs's job of allocating the
808 * test_io.c (test_close): IO manager which is used for testing
811 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
813 * inode.c (ext2fs_get_next_inode): Separate out the function of
814 setting up for a new block group to get_next_blockgroup().
815 Separate out the function of reading in blocks of the
816 inode table to get_next_blocks().
818 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
820 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
821 blocks to the badblock list in sorted order. This allows
822 badblocks_list_test to be coded using a binary search for
825 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
827 * Release of E2fsprogs version 1.06

831 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
832 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
835 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
836 set, then only write out the master superblock.
838 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
840 * block.c (ext2fs_block_iterate): Fixed bug which caused
841 block_iterate to fail to handle HURD created filesystems;
842 it tested the inode translator field before the inode was
845 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
847 * initialize.c (ext2fs_initialize): Make sure the description for
848 the inode bitmap is set correctly.

876 * namei.c (ext2fs_follow_link): New function.
877 (ext2fs_namei): Extended to have support for chasing
878 symbolic links. ext2fs_namei() still returns an inode
879 which is a symbolic link. Symbolic links are only chased
880 while resolving the containing directory. To chase
881 symbolic links of the final result, use
882 ext2fs_follow_link().
884 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
886 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
888 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
889 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

893 * initialize.c (ext2fs_initialize): On systems where the byte
894 order is not i386 compatible, set the swap_byte flag.
896 * inode.c (inocpy_with_swap): Check to see if inode contains a
897 fast symlink before swapping the inode block fields. This
898 required adding a new argument to inocpy_with_swap to
899 determine whether the mode field is in host order or not.
901 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
903 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
904 the sparc, if EXT2_STD_BITOPS set, use the standard
905 i386-compatible bitmask operations, instead on the
906 non-standard native bitmask operators.
908 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
910 * block.c (ext2fs_block_iterate): Cause block iterator to return
911 the HURD translator block (along with everything else).
912 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
913 iterator, then don't return any meta data blocks
914 (including the HURD translator).

930 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
932 * openfs.c (ext2fs_open): If the blocksize in the superblock is
933 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
934 that's a basic value that must be correct for the rest of
937 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
940 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1049 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1050 Move these functions to freefs.c.
1052 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1053 descriptors shadow memory to keep purify quiet. (This
1054 also has the nice benefit that the unused portion of the
1055 shadow descriptors are zeroed out.)
1057 * dirblock.c (ext2fs_write_dir_block): We need to use
1058 dirent->rec_len *before* it's byteswapped to find the
1059 location of the next directory structure!
1061 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1062 cause ext2fs_new_inode to loop infinitely if we're trying
1063 to allocate an inode in group #0 and there are no free
1064 inodes at all in the system.
1066 * closefs.c: #include <errno.h> if it exists.
1068 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1070 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for
1071 BLOCK_FLAG_APPEND. Added documentation for the block
1074 Sat Aug 5 11:44:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1076 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1077 installation directories correctly.
1079 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1081 * namei.c (process_dir_block):
1082 * mkdir.c (ext2fs_mkdir):
1083 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1084 to read/write the directory block.
1086 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1087 file containing functions for reading and writing
1088 directory blocks (byte swapping if necesssary)
1090 * block.c (block_iterate_ind, block_iterate_dind,
1091 block_iterate_tind): Byte swap the block addresses if
1092 EXT2_SWAP_BYTES is set (and swap them back before writing
1095 * inode.c (inocpy_with_swap): New function.
1096 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1097 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1099 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1100 the superblock and group descriptors before writing it out.
1102 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1103 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1104 and group descriptors.
1106 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1107 to desp ext2 filesystem structures.
1109 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1110 supplied by Pete A. Zaitcev so that the C language
1111 versions of these functions are more portable. They will
1112 now work on both little and big endian systems, and the
1113 assumption that 32-bit integers are used is gone.
1115 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1116 doing byte swapping.
1118 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1119 byte swapping should take place.
1121 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1123 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
1124 ext2fs_compare_inode_bitmap_end): Added new file
1125 containing routines to compare bitmaps.
1127 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1128 Added new error codes.
1130 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1132 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1133 if the magic number is correct, it will be allocated.
1135 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1137 * block.c (block_iterate_ind, block_iterate_dind,
1138 block_iterate_tind): Don't recompute block_nr each loop;
1139 just increment it! Factor check of BLOCK_FLAG_APPEND out
1140 of the loop. Factor mask of BLOCK_CHANGED into changed
1141 variable out of the loop. (block_iterate_ind, in
1142 particular, gets called a lot, so every little
1143 optimization helps.)
1145 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1147 * block.c (block_iterate_ind, block_iterate_dind,
1148 block_iterate_tind): Precompute limit of loop to speed up
1149 block_iterate_ind and company.
1151 * bitops.h (ext2fs_fast_mark_block_bitmap,
1152 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1153 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1154 ext2fs_fast_test_inode_bitmap): Add fast version of these
1155 functions, which don't do range checking.
1157 * bitops.h (ext2fs_get_block_bitmap_start,
1158 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1159 ext2fs_get_inode_bitmap_end): Add new accessor functions
1160 which return the start and end points of the bitmaps.
1162 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1164 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1165 instead of llseek. The errno if the offset is too large
1166 and lseek is not supported should be EINVAL, not -EINVAL.
1168 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1170 * Makefile.in: Added support for ELF shared libraries.
1171 Fixed typos in the compilation rules.
1172 (distclean): Added Makefile.
1174 * llseek.c (llseek): New function, if llseek() does not exist in the
1176 (ext2_llseek): Changed to call llseek().
1178 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1180 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1182 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1184 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1186 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1187 the S_*, which are normally defined in <sys/stat.h>. This
1188 allows us to compile e2fsprogs on a non-Linux system,
1189 which may have a different value for S_IFDIR.
1191 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1193 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1194 this is a user-mode application!
1196 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1198 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1199 __linux__ so that non-linux systems won't see it.
1201 * alloc.c: Include <errno.h> if possible.
1202 * badblocks.c: Ditto.
1203 * bb_inode.c: Ditto.
1206 * expanddir.c: Ditto.
1207 * get_pathname.c: Ditto.
1208 * initialize.c: Ditto.
1215 * rw_bitmaps.c: Ditto.
1218 * Makefile.in: Rewritten to conform to GNU coding standards and
1219 support separate compilation directories.
1221 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1223 * initialize.c (ext2fs_initialize): Don't allow more than one
1224 bitmaps's worth of inodes in a group.
1226 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1228 * llseek.c (ext2_llseek): Added error checking to the llseek()
1229 compat code to protect against overflow. This only
1230 applies to 1.0 and early 1.1 kernels, which don't support
1231 the llseek() system call.
1233 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1235 * unix_io.c (unix_open): Initialize the read_error and write_error
1236 io_channel pointers to be null.
1238 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1239 found, clear it but don't try to update the filesystem
1240 accounting information, since that's hopeless anyway.
1242 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1243 bloblock_iterate_tind): Check to see if the indirect blocks are
1244 valid before trying to read them.
1246 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1247 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1249 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1250 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1251 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1252 illegal block or inode number is passed in, return instead
1253 of trying to test, set, or clear the bit.
1255 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1257 * Makefile: Added a dummy install target in case shared libraries
1260 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1262 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1263 the real last block of the bitmap should be calculated.
1265 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
1267 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1268 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1269 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1270 ext2fs_free_block_bitmap): Add magic number checking for
1271 the inode and block bitmaps.
1273 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1274 magic number for a block bitmap instead of an inode bitmap.
1276 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1277 magic number checking for the inode_scan structure.
1279 * badblocks.c (badblocks_list_free, badblocks_list_add,
1280 badblocks_list_test, badblocks_list_iterate_begin,
1281 badblocks_list_iterate, badblocks_list_iterate_end): Add
1282 magic number checking for the badblocks_list and
1283 badblocks_iterate structures.
1285 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1286 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1287 unix_write_blk, unix_flush): Add magic number checking
1288 both for io_channel structure and unix_private_data
1291 * openfs.c (ext2fs_open): Add check for io_manager structure's
1294 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1295 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1296 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1297 * read_bb.c (ext2fs_read_bb_inode):
1298 * read_bb_file.c (ext2fs_read_bb_FILE):
1299 * newdir.c (ext2fs_new_dir_block):
1300 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
1301 * link.c (ext2fs_link, ext2fs_unlink):
1302 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

1307 * block.c (ext2fs_block_iterate):
1308 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1309 ext2fs_allocate_block_bitmap):
1310 * bb_inode.c (ext2fs_update_bb_inode):
1311 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1312 * check_desc.c (ext2fs_check_desc):
1313 * closefs.c (ext2fs_close, ext2fs_flush):
1314 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1319 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1320 openfs.c into its own file.
1322 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1323 structure magic numbers.
1325 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1326 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1327 someone uses the -b option to specify the use of the backup
1328 superblock --- this usually means that the main superblock is
1332 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1333 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1334 revision level to the superblock.
1336 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1343 * initialize.c: Completely revamped the inode and block bitmap
1344 structures, so that they can be better chance of being extensible
1345 in a shared library. They are now their own type, instead of
1346 being a char *. Also, the function signatures of
1347 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1348 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1349 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1350 changed to eliminate the ext2_filsys argument, since it is no
1353 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1355 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1356 system call if available.
1358 * llseek.c: new file. This is the stub calling the llseek system
1359 call which allows supports for 2GB+ file systems.
1361 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1362 the creator operating system.
1364 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1366 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1367 the group descriptor statistics in addition to everything else.
1368 This relieves mke2fs of the responsibility of doing it.
1370 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1371 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1372 not the generic C function equivalents should be included or not.
1374 * openfs.c (ext2fs_open): If a superblock is specified, then use
1375 the backup group descriptors that go along with this superblock,
1376 instead of using the primary group descriptors. This allows
1377 e2fsck to recover filesystems where the primary group descriptors
