1 1999-06-21 <tytso@rsts-11.mit.edu>
3 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
4 directory entry before calling the callback function.
5 This should prevent some core dumps of insufficiently
6 paranoid callback functions.
8 1999-05-29 <tytso@rsts-11.mit.edu>
10 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
12 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
13 that we don't handle writing yet (we do). Fixed bug where
14 we weren't allocating a big enough buffer for ext2_bmap.
16 1999-05-03 <tytso@rsts-11.mit.edu>
18 * openfs.c (ext2fs_open): Check to make sure that the number of
19 blocks per group is not zero --- if so, it must be a bad
22 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
24 * Release of E2fsprogs 1.14
26 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
28 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
29 the inode number is zero; if it's zero, return
30 EXT2_ET_BAD_INODE_NUM.
32 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
34 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
35 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
38 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
40 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
41 non-Linux case to use EINVAL by default, unless it isn't
42 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
45 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
47 * Release of E2fsprogs 1.13
49 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
51 * Makefile.in: Updated dependencies.
53 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
55 * initialize.c (ext2fs_initialize): Make sure that we allocate
56 enough inodes so that we can make a valid filesystem.
58 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
60 * rw_bitmaps.c: Fixed signed/unsigned warnings.
62 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
65 * dblist.c (make_dblist): Add safety check in case the dblist
66 pointer passed in is null (in which case, assign it to
67 fs->dblist). Fixed some signed/unsigned warnings.
69 * bmap.c: Make addr_per_block be of type blk_t to avoid
70 signed/unsigned warnings.
72 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
75 * get_pathname.c (get_pathname_proc): Use return value from
76 ext2fs_get_mem, instead of checking if &gp->name is
79 * dir_iterate.c (ext2fs_process_dir_block):
80 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
81 from the function declaration.
83 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
84 return the error directly instead of jumping to the
85 cleanup routine, since we don't need to do any cleanup.
87 * alloc_table.c (ext2fs_allocate_group_table): Make this
88 function take a dgrp_t for its group argument.
90 * ext2fs.h: Make dgrp_t an __u32 type, and make
91 fs->desc_group_count be of type dgrp_t.
93 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
95 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
96 than 10 blocks when we need to expand the size of the
99 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
101 * Release of E2fsprogs 1.12
103 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
105 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
106 appropriate for all of the block group copies, so that
107 it's clear where the beginning of the filesystem is on the
108 disk. (For when the partition table gets scrod.)
110 * ext2fs.h: Change the name of the feature from
111 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
112 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
114 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
116 * inode.c (get_next_blockgroup): Fix bug where if
117 get_next_blockgroup() is called early because of a missing
118 inode table in a block group, the current_inode counter
119 wasn't incremented correctly.
121 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
123 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
124 against a completely trashed bad block inode.
126 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
128 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
129 the stride length hits a bad value, we retry the block
130 allocation starting at the beginning of the block group.
132 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
133 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
134 e2_blkcnt_t to avoid collision with LFS API.
136 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
138 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
139 way that avoids overflows on disk sizes greater than 4GB.
141 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
143 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
144 return type for comparison functions for qsort.
146 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
149 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
151 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
154 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
155 evade a potential problem with glibc's header files trying
156 to spike out linux/types.h.
158 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
159 include the old size of the memory, which is needed for
160 some braindamaged memory allocation systems that don't
163 * badblocks.c (ext2fs_badblocks_list_add):
164 bb_inode.c (clear_bad_block_proc):

175 convention. Fix uninstall rules to take $(DESTDIR) into
178 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
180 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
181 with 32 bit longs, then we need to manually define __s64
182 and __u64, since the current kernel header files don't
183 define these if __STRICT_ANSI__ is defined. This is a
184 problem if we are compiling with full GCC warnings, since
185 we do need 64 bit support.
187 * Makefile.in (OBJS): Remove bmove.o from files to be built,
188 since we're not using ext2fs_move_blocks() and there
189 is some question as to its usefulness in its current
192 * bmap.c (block_bmap): Remove unused function.
194 * bmove.c (process_block): Fix -Wall warning.
196 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
198 * block.c (ext2fs_block_iterate3): Make the ref_offset field
199 contain the offset into the inode.i_blocks array when
200 ref_block is zero. Since we haven't done a formal
201 release of e2fsprogs since block_iterate2 was first
202 introduced, I removed block_iterate2, and renamed
203 block_iterate3 to be block_iterate2.
205 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
206 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
207 use of block_iterate and block_iterate2 to
208 block_iterate2 with the new prototype for the
209 interator function. (using blkcnt_t forr blockcount)
211 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
213 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
214 s_prealloc_blocks, s_prealloc_dir_blocks). Added
215 conditional defines of new features COMPAT_DIR_PREALLOC,
216 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
217 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
218 the library to declare that we support COMPAT_DIR_PREALLOC,
219 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
221 * fileio.c: Rename function ext2fs_file_llseek to be
222 ext2fs_file_lseek, which is more accurate.
224 * block.c: Add new function ext2fs_block_iterate3 which calls
225 the iterator function with the blockcount argument of
226 type blkcnt_t. This version of the function is
227 allowed to handle large files; the other fucntions are
230 * ext2fs.h: Add new type blkcnt_t
232 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
234 * block.c (ext2fs_block_iterate2): Fix bug where the block count
235 field wasn't getting correctly incremented for sparse
236 files when the indirect or doubly-indirect block
237 specified in the inode was zero.
239 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
241 * unlink.c (unlink_proc):
242 * lookup.c (lookup_proc):
243 * link.c (link_proc):
244 * get_pathname.c (get_pathname_proc):
245 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
246 from dirent->name_len, so it can be used for other
249 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
250 and indicate that we have support for this incompatible
253 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
255 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
257 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
259 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
260 number of directories when the block group information is
263 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
265 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
266 inode table is missing so that we catch the case where the
267 first block group is missing.
269 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
272 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
274 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
276 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
278 * test_io.c (test_flush): Add a debugging printf when the flush
281 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
282 read in, return right away.
284 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
286 * bitops.h: Don't try to do i386 inline asm functions if the
289 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
290 instead of linux/types.h, and e2_bitops.h instead of
293 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
296 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
298 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
299 so that we don't need to call get_next_blockgroup() the
300 first time around. Saves a bit of time, and prevents us
301 from needing to assign -1 to current_group (which is an
304 * icount.c (insert_icount_el): Cast the estimated number of inodes
305 from a float to an ino_t.
307 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

317 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
318 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
319 defined, then assume all of the
320 ext2-specific header files are in a flat directory.
322 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
323 all assignments from void * to be compatible with C++.

330 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
332 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
333 avoid C++ namespace clash.
335 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
336 avoid C++ namespace clash.
338 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
339 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
340 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,

344 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
346 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
347 paranoid about validating the directory counts from the
348 block group information.
350 * all files: Don't include stdlib.h anymore; include it in
351 ext2_fs.h, since that file requires stdlib.h
353 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
355 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
356 bitmap is loaded, and return an error if it is not.
357 (expand_dir_proc): Only use ext2fs_write_dir_block when
358 writing a directory block, not when writing out a fresh
361 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
363 * Makefile.in, tst_getsize.c: Added new file which is used to test

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

445 * inode.c (ext2fs_check_directory): Add support for the callback
446 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.

450 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
451 padding of the bitmap to be all one's.
453 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
455 * llseek.c: Added missing semicolon to glibc fixup declaration of
458 * bmove.c: Add #include of errno.h
460 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
462 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
463 added a new field to the io_channel (app_data).
465 * io.h: Add a new element to the io_channel structure, app_data.
467 * initialize.c, openfs.c: Set io->app_data to point at the
470 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
472 * io.h: Change the prototype of ext2fs_llseek() to use int's
473 instead of unsigned int's.
475 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
476 to make life easer for GNU Libc 2.
478 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
479 filesystem has its bitmaps stored as 32-bit words with bit
480 0 as the LSB of each word. Thus a bitmap with only bit 0
481 set would be, as a string of bytes, 00 00 00 01 00 ... To
482 cope with this, we byte-reverse each word of a bitmap if
483 we have a big-endian filesystem, that is, if we are *not*
484 byte-swapping other word-sized numbers.
486 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

553 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
555 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
556 is zero, then return EXT2_IO_LLSEEK_FAILED.
558 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.

565 the number of directory blocks in dblist.
567 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
569 * unix_io.c (unix_flush): Make the io_channel flush function do a
570 fsync to flush the kernel buffers to disk.
572 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
574 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
575 current inode number wasn't being set by the
576 goto_blockgroup function.
578 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
580 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
581 of blocks which need to be moved, and moves those blocks
582 to another location in the filesystem.
584 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
585 bitmap, make sure all of the new parts of the bitmap are
588 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
590 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
591 wasn't being returned to the caller.
593 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
594 ext2fs_allocate_group_table() which sets the group tables
595 for a particular block group. The relevant code was
596 factored out of ext2fs_allocate_tables().
598 * dblist.c (make_dblist): Adjust the initial size of the directory
599 block list to be a bit more realistic (ten plus twice the
600 number of directories in the filesystem).
602 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
604 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
605 ext2fs_badblocks_list_test would test the list (and exceed
606 array boundaries) if there were no bad blocks on the bad
607 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
609 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
611 * Release of E2fsprogs version 1.10
613 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
615 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
616 inode and block bitmaps based on the RAID 0 stride
617 parameter (which is passed by mke2fs).
619 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
620 mke2fs to communicate the stride length to
621 ext2fs_allocate_tables()
623 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>

635 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
637 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
638 filesystem has no free blocks, ext2fs_new_block would loop
641 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
643 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
644 free if refcount goes to zero.

660 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
662 (unix_close, test_close): Decrement the refcount and only
663 close the io_channel if the refcount goes to 0.
665 * io.h: Add refcount to the io_channel structure. Add new macro
666 interface io_channel_bumpcount() to bump the refcount.
668 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
670 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
671 cache in the filesystem handle, instead of the inode cache
672 in a static variable.
674 * freefs.c: Added static function to free the inode cache (called by
677 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
679 * ext2fs.h: Added pointer to the inode_cache structure.
681 * block.c (block_iterate_ind, block_iterate_dind,
682 block_iterate_tind): If there are holes in the indirect,
683 doubly indirect, or triply indirect blocks, increment the
684 block count field automatically.

690 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
692 * version.c (ext2fs_parse_version_string): Check the passed in
693 version string (instead of the hard-coded one).
695 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
696 greater filesystem size, clamp it to prevent allocating a
697 block or inode bitmap beyond the filesystem.
699 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
700 overhead calculation was accidentally removed.
702 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
704 * Release of E2fsprogs version 1.08

709 block of a dblist entry, given the directory inode and
712 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
714 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
715 inode bitmaps at staggered locations across the block
716 groups, to avoid concentrating the bitmaps on a small
717 number of disks when using striped RAID arrays.
719 * initialize.c (ext2fs_initialize): By default, choose the maximum
720 possible number of blocks per group (based on the size of
721 the bitmaps in the blocksize).
723 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
725 * initialize.c (ext2fs_initialize): Add support for
726 EXT2_COMPAT_SPARSE_SUPER feature.
728 * closefs.c (ext2fs_bg_has_super): New function to determine
729 whether or a particular block group should have a
730 superblock and block group descriptor. Used for the
731 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
732 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
733 or not the superblock should be written out for the block
736 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
737 for sparse duplicate superblocks.
739 * version.c (ext2fs_get_library_version): New function which
740 returns the library version.
742 * version.c (ext2fs_parse_version_string): New function which
743 parses a version string and returns a version number,
744 so application programs can compare version numbers as
747 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
749 * icount.c (ext2fs_create_icount): Change function so that it also
750 takes a new argument which contains a "hint" icount
751 structure. This "hint" icount allows the create function
752 to set up the sorted list in advance. This reduces
753 significantly the amount of data moving needed to insert
754 these inodes into the list later.
756 * icount.c (ext2fs_icount_validate): New function which validates
757 that the icount structure's rep invariant.
759 * icount.c (get_icount_el): Completely revamped implementation
760 to subsume put_icount_el(). Put_icount_el() used to
761 use an O(N) implementation to insert in the middle
762 of the icount list. It now uses a O(ln N) to search
763 for where the icount should be inserted, and then uses
764 a memcpy to move the list down (instead of a for loop).
766 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
767 ext2fs_icount_increment, ext2fs_icount_decrement): Check
768 to see if the inode is within bounds; if it isn't, return
771 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
772 when a bad inode number is passed to test_generic_bitmap
773 to be EXT2FS_TEST_ERROR instead of the wrong
776 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
778 * Release of E2fsprogs version 1.07
780 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
782 * Makefile.in (ELF_VERSION): Change version to be 2.2
784 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
786 * alloc.c (ext2fs_get_free_blocks): Change routine to use
787 ext2fs_fast_test_block_bitmap_range().
789 * bitops.h (ext2fs_fast_test_block_bitmap_range,
790 ext2fs_test_block_bitmap_range: New inline functions which
791 test to see whether a contiguous range of blocks is
794 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
796 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
797 use ext2fs_badblocks_* instead of badblocks_*
799 * bb_compat.c: New file which translates between old badblocks_*()
800 names to ext2fs_badblocks_*()
802 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
803 link.c (since e2fsck doesn't use ext2fs_unlink()).
805 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
806 bitmap resizing routine moved from bitmaps.c, since e2fsck
807 doesn't need to use this function.
809 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
810 since e2fsck only needs ext2fs_lookup.
812 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
814 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
815 already set; this is needed so that programs like dump
816 which use the inode scan functions will deal with
817 filesystems that have bad blocks in the inode table.
819 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
821 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
822 Moved to ext2fsP.h, since it doesn't need to be part of
823 the public interface.
825 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
827 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
829 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
830 directory block list abstraction. (Code moved from
833 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
834 to inode.c (since no one else should be peeking inside it!)
836 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
838 * openfs.c (ext2fs_open): Check the feature set in the ext2
839 superblock, and refuse to open filesystems if they contain
840 incompatible features. (Can be overriden with the
843 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
845 * block.c (ext2fs_block_iterate2): Added new function
846 ext2fs_block_iterate2 which changes the function
847 signature of the callback function to include the
848 referencing block and offset.
850 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
851 ext2fs_inode_scan_goto_blockgroup which allows an
852 application to jump to a particular block group while
855 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
857 * dirblock.c: Include string.h, since we use memcpy().
859 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
861 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
862 a long not an int; this doesn't matter on i386 machines,
863 but it does on Alpha's.
865 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
867 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
868 table pointer is NULL, then return an error indicating
869 that the inode table is missing.
870 (get_next_blockgroup, get_next_blocks,
871 ext2fs_get_next_inode): Don't treat a missing inode table
872 as permanent error. Return MISSING_INODE_TABLE, but as an
873 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
875 * rw_bitmaps.c (ext2fs_write_block_bitmap,
876 ext2fs_write_inode_bitmap): If the inode or block bitmap
877 block is zero, then don't write out the inode or block
878 bitmap. The idea here is to avoid stomping on the
880 (read_bitmaps): If the inode or block bitmap block is
881 zero, then fill in that portion of the inode or block
882 bitmap with all zeros.
884 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
885 blocks in inode table when the inode table size is
886 non-standard (and can therefore span blocks).
888 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
890 * alloc.c (ext2fs_new_block): Fix fencepost error in
891 ext2fs_new_block; make sure we don't try to allocate the
892 first block beyond the end of the filesystem.
894 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
896 * inode.c (check_for_inode_bad_blocks): New function called by
897 get_next_blocks() to avoid reading in bad blocks marked in
898 fs->badblocks. Inodes located in bad blocks are returned
899 by ext2fs_get_next_inode() returns the error code
900 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
902 * alloc_tables.c (ext2fs_allocate_tables): New function which
903 performs the part of mke2fs's job of allocating the
906 * test_io.c (test_close): IO manager which is used for testing
909 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
911 * inode.c (ext2fs_get_next_inode): Separate out the function of
912 setting up for a new block group to get_next_blockgroup().
913 Separate out the function of reading in blocks of the
914 inode table to get_next_blocks().
916 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
918 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
919 blocks to the badblock list in sorted order. This allows
920 badblocks_list_test to be coded using a binary search for
923 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
925 * Release of E2fsprogs version 1.06

929 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
930 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
933 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
934 set, then only write out the master superblock.
936 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
938 * block.c (ext2fs_block_iterate): Fixed bug which caused
939 block_iterate to fail to handle HURD created filesystems;
940 it tested the inode translator field before the inode was
943 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
945 * initialize.c (ext2fs_initialize): Make sure the description for
946 the inode bitmap is set correctly.
948 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
950 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
952 * Release of E2fsprogs version 1.05
954 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
956 * initialize.c: Override the kernel's idea of default
957 checkinterval from 0 (never) to 180 days.

971 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
974 * namei.c (ext2fs_follow_link): New function.
975 (ext2fs_namei): Extended to have support for chasing
976 symbolic links. ext2fs_namei() still returns an inode
977 which is a symbolic link. Symbolic links are only chased
978 while resolving the containing directory. To chase
979 symbolic links of the final result, use
980 ext2fs_follow_link().
982 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
984 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
986 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
987 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
989 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
991 * initialize.c (ext2fs_initialize): On systems where the byte
992 order is not i386 compatible, set the swap_byte flag.
994 * inode.c (inocpy_with_swap): Check to see if inode contains a
995 fast symlink before swapping the inode block fields. This
996 required adding a new argument to inocpy_with_swap to
997 determine whether the mode field is in host order or not.
999 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1001 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1002 the sparc, if EXT2_STD_BITOPS set, use the standard
1003 i386-compatible bitmask operations, instead on the
1004 non-standard native bitmask operators.
1006 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1008 * block.c (ext2fs_block_iterate): Cause block iterator to return
1009 the HURD translator block (along with everything else).
1010 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1011 iterator, then don't return any meta data blocks
1012 (including the HURD translator).
1014 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1016 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1018 * uuid.c: New file, containing UUID utility functions.
1020 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1022 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1024 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1026 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1028 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1030 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1031 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1032 that's a basic value that must be correct for the rest of
1033 the library to work.
1035 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1038 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1040 * Release of E2fsprogs version 1.04

1048 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
1049 Change the m68k bit numbering for bitmasks to match with
1050 the bit numbering used by all other ext2 implementations.
1052 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1054 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

1086 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1087 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1088 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1089 to avoid conflicts with with kernel include files. Also
1090 rename ADDR and CONST_ADDR to EXT2FS_ADDR and

1095 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1097 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1098 s_def_resuid and s_def_resgid for backwards compatibility.
1100 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
1102 * bitops.h: Added #ifdef's for Sparc.
1104 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
1106 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
1109 * closefs.c: #include <string.h> to pick up memset() declaration
1111 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1113 * Makefile.in: Added support for BSD shared libraries.
1115 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1118 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1120 * unix_io.c (unix_open): Add a double check; if the passed in name
1121 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1123 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1125 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

1132 * getsize.c (ext2fs_get_device_size): Add support for reading the
1133 partition size from a BSD disk label.
1135 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1137 * getsize.c (ext2fs_get_device_size): New function that determins
1138 the size of a device. Used by mke2fs and e2fsck.

1147 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1148 Move these functions to freefs.c.
1150 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1151 descriptors shadow memory to keep purify quiet. (This
1152 also has the nice benefit that the unused portion of the
1153 shadow descriptors are zeroed out.)
1155 * dirblock.c (ext2fs_write_dir_block): We need to use
1156 dirent->rec_len *before* it's byteswapped to find the
1157 location of the next directory structure!
1159 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1160 cause ext2fs_new_inode to loop infinitely if we're trying
1161 to allocate an inode in group #0 and there are no free
1162 inodes at all in the system.
1164 * closefs.c: #include <errno.h> if it exists.
1166 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1168 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1174 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1175 installation directories correctly.
1177 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1179 * namei.c (process_dir_block):
1180 * mkdir.c (ext2fs_mkdir):

1182 to read/write the directory block.
1184 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1185 file containing functions for reading and writing
1186 directory blocks (byte swapping if necesssary)
1188 * block.c (block_iterate_ind, block_iterate_dind,
1189 block_iterate_tind): Byte swap the block addresses if
1190 EXT2_SWAP_BYTES is set (and swap them back before writing
1193 * inode.c (inocpy_with_swap): New function.
1194 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1195 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1197 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1198 the superblock and group descriptors before writing it out.
1200 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1201 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1202 and group descriptors.
1204 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1205 to desp ext2 filesystem structures.
1207 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1208 supplied by Pete A. Zaitcev so that the C language
1209 versions of these functions are more portable. They will
1210 now work on both little and big endian systems, and the
1211 assumption that 32-bit integers are used is gone.
1213 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1214 doing byte swapping.
1216 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1217 byte swapping should take place.
1219 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1221 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
1222 ext2fs_compare_inode_bitmap_end): Added new file
1223 containing routines to compare bitmaps.
1225 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1226 Added new error codes.
1228 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1230 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1231 if the magic number is correct, it will be allocated.
1233 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1235 * block.c (block_iterate_ind, block_iterate_dind,
1236 block_iterate_tind): Don't recompute block_nr each loop;
1237 just increment it! Factor check of BLOCK_FLAG_APPEND out
1238 of the loop. Factor mask of BLOCK_CHANGED into changed
1239 variable out of the loop. (block_iterate_ind, in
1240 particular, gets called a lot, so every little
1241 optimization helps.)
1243 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1245 * block.c (block_iterate_ind, block_iterate_dind,
1246 block_iterate_tind): Precompute limit of loop to speed up
1247 block_iterate_ind and company.
1249 * bitops.h (ext2fs_fast_mark_block_bitmap,
1250 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1251 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1252 ext2fs_fast_test_inode_bitmap): Add fast version of these
1253 functions, which don't do range checking.
1255 * bitops.h (ext2fs_get_block_bitmap_start,
1256 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1257 ext2fs_get_inode_bitmap_end): Add new accessor functions
1258 which return the start and end points of the bitmaps.
1260 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1262 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1263 instead of llseek. The errno if the offset is too large
1264 and lseek is not supported should be EINVAL, not -EINVAL.
1266 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1268 * Makefile.in: Added support for ELF shared libraries.
1269 Fixed typos in the compilation rules.
1270 (distclean): Added Makefile.
1272 * llseek.c (llseek): New function, if llseek() does not exist in the
1274 (ext2_llseek): Changed to call llseek().
1276 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1278 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1280 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1282 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1284 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1285 the S_*, which are normally defined in <sys/stat.h>. This
1286 allows us to compile e2fsprogs on a non-Linux system,
1287 which may have a different value for S_IFDIR.
1289 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1291 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1292 this is a user-mode application!
1294 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1296 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1297 __linux__ so that non-linux systems won't see it.
1299 * alloc.c: Include <errno.h> if possible.
1300 * badblocks.c: Ditto.
1301 * bb_inode.c: Ditto.
1304 * expanddir.c: Ditto.
1305 * get_pathname.c: Ditto.
1306 * initialize.c: Ditto.
1313 * rw_bitmaps.c: Ditto.
1316 * Makefile.in: Rewritten to conform to GNU coding standards and
1317 support separate compilation directories.
1319 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1321 * initialize.c (ext2fs_initialize): Don't allow more than one
1322 bitmaps's worth of inodes in a group.
1324 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1326 * llseek.c (ext2_llseek): Added error checking to the llseek()
1327 compat code to protect against overflow. This only
1328 applies to 1.0 and early 1.1 kernels, which don't support
1329 the llseek() system call.
1331 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1333 * unix_io.c (unix_open): Initialize the read_error and write_error
1334 io_channel pointers to be null.
1336 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1337 found, clear it but don't try to update the filesystem
1338 accounting information, since that's hopeless anyway.
1340 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1341 bloblock_iterate_tind): Check to see if the indirect blocks are
1342 valid before trying to read them.
1344 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1345 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1347 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1348 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1349 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1350 illegal block or inode number is passed in, return instead
1351 of trying to test, set, or clear the bit.
1353 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1355 * Makefile: Added a dummy install target in case shared libraries
1358 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1360 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

1365 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1366 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1367 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1368 ext2fs_free_block_bitmap): Add magic number checking for
1369 the inode and block bitmaps.
1371 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1372 magic number for a block bitmap instead of an inode bitmap.
1374 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1375 magic number checking for the inode_scan structure.
1377 * badblocks.c (badblocks_list_free, badblocks_list_add,
1378 badblocks_list_test, badblocks_list_iterate_begin,
1379 badblocks_list_iterate, badblocks_list_iterate_end): Add
1380 magic number checking for the badblocks_list and
1381 badblocks_iterate structures.
1383 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1384 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1385 unix_write_blk, unix_flush): Add magic number checking
1386 both for io_channel structure and unix_private_data
1389 * openfs.c (ext2fs_open): Add check for io_manager structure's
1392 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1393 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1394 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1395 * read_bb.c (ext2fs_read_bb_inode):
1396 * read_bb_file.c (ext2fs_read_bb_FILE):
1397 * newdir.c (ext2fs_new_dir_block):
1398 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
1399 * link.c (ext2fs_link, ext2fs_unlink):
1400 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

1407 ext2fs_allocate_block_bitmap):
1408 * bb_inode.c (ext2fs_update_bb_inode):
1409 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1410 * check_desc.c (ext2fs_check_desc):
1411 * closefs.c (ext2fs_close, ext2fs_flush):
1412 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1417 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1418 openfs.c into its own file.
1420 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1421 structure magic numbers.
1423 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1424 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1425 someone uses the -b option to specify the use of the backup
1426 superblock --- this usually means that the main superblock is
1430 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1431 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1432 revision level to the superblock.
1434 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1441 * initialize.c: Completely revamped the inode and block bitmap
1442 structures, so that they can be better chance of being extensible
1443 in a shared library. They are now their own type, instead of
1444 being a char *. Also, the function signatures of
1445 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1446 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1447 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1448 changed to eliminate the ext2_filsys argument, since it is no
1451 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1453 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1454 system call if available.
1456 * llseek.c: new file. This is the stub calling the llseek system
1457 call which allows supports for 2GB+ file systems.
1459 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1460 the creator operating system.
1462 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1464 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1465 the group descriptor statistics in addition to everything else.
1466 This relieves mke2fs of the responsibility of doing it.
1468 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1469 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1470 not the generic C function equivalents should be included or not.
1472 * openfs.c (ext2fs_open): If a superblock is specified, then use
1473 the backup group descriptors that go along with this superblock,
1474 instead of using the primary group descriptors. This allows
1475 e2fsck to recover filesystems where the primary group descriptors
