7 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
8 kernels that use i_generation instead of i_version. Patch
9 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
11 1999-06-21 <tytso@valinux.com>
13 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
14 directory entry before calling the callback function.
15 This should prevent some core dumps of insufficiently
16 paranoid callback functions.
18 1999-05-29 <tytso@rsts-11.mit.edu>
20 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
22 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
23 that we don't handle writing yet (we do). Fixed bug where
24 we weren't allocating a big enough buffer for ext2_bmap.
26 1999-05-03 <tytso@rsts-11.mit.edu>
28 * openfs.c (ext2fs_open): Check to make sure that the number of
29 blocks per group is not zero --- if so, it must be a bad
32 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
34 * Release of E2fsprogs 1.14
36 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
38 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
39 the inode number is zero; if it's zero, return
40 EXT2_ET_BAD_INODE_NUM.
42 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
44 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
45 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
48 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
50 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
51 non-Linux case to use EINVAL by default, unless it isn't
52 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
55 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
57 * Release of E2fsprogs 1.13
59 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
61 * Makefile.in: Updated dependencies.
63 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
65 * initialize.c (ext2fs_initialize): Make sure that we allocate
66 enough inodes so that we can make a valid filesystem.
68 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>

72 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
75 * dblist.c (make_dblist): Add safety check in case the dblist
76 pointer passed in is null (in which case, assign it to
77 fs->dblist). Fixed some signed/unsigned warnings.
79 * bmap.c: Make addr_per_block be of type blk_t to avoid
80 signed/unsigned warnings.
82 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
85 * get_pathname.c (get_pathname_proc): Use return value from
86 ext2fs_get_mem, instead of checking if &gp->name is
89 * dir_iterate.c (ext2fs_process_dir_block):
90 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
91 from the function declaration.
93 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
94 return the error directly instead of jumping to the
95 cleanup routine, since we don't need to do any cleanup.
97 * alloc_table.c (ext2fs_allocate_group_table): Make this
98 function take a dgrp_t for its group argument.
100 * ext2fs.h: Make dgrp_t an __u32 type, and make
101 fs->desc_group_count be of type dgrp_t.
103 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
105 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
106 than 10 blocks when we need to expand the size of the
109 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
111 * Release of E2fsprogs 1.12
113 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
115 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
116 appropriate for all of the block group copies, so that
117 it's clear where the beginning of the filesystem is on the
118 disk. (For when the partition table gets scrod.)
120 * ext2fs.h: Change the name of the feature from
121 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
122 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
124 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
126 * inode.c (get_next_blockgroup): Fix bug where if
127 get_next_blockgroup() is called early because of a missing
128 inode table in a block group, the current_inode counter
129 wasn't incremented correctly.
131 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
133 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
134 against a completely trashed bad block inode.
136 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
138 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
139 the stride length hits a bad value, we retry the block
140 allocation starting at the beginning of the block group.
142 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
143 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
144 e2_blkcnt_t to avoid collision with LFS API.
146 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
148 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
149 way that avoids overflows on disk sizes greater than 4GB.
151 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
153 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
154 return type for comparison functions for qsort.
156 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
159 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
161 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
164 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
165 evade a potential problem with glibc's header files trying
166 to spike out linux/types.h.
168 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
169 include the old size of the memory, which is needed for
170 some braindamaged memory allocation systems that don't
173 * badblocks.c (ext2fs_badblocks_list_add):
174 bb_inode.c (clear_bad_block_proc):

178 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
179 pass the old size of the memory to be resized to
182 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>

185 convention. Fix uninstall rules to take $(DESTDIR) into
188 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
190 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
191 with 32 bit longs, then we need to manually define __s64
192 and __u64, since the current kernel header files don't
193 define these if __STRICT_ANSI__ is defined. This is a
194 problem if we are compiling with full GCC warnings, since
195 we do need 64 bit support.
197 * Makefile.in (OBJS): Remove bmove.o from files to be built,
198 since we're not using ext2fs_move_blocks() and there
199 is some question as to its usefulness in its current
202 * bmap.c (block_bmap): Remove unused function.
204 * bmove.c (process_block): Fix -Wall warning.
206 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
208 * block.c (ext2fs_block_iterate3): Make the ref_offset field
209 contain the offset into the inode.i_blocks array when
210 ref_block is zero. Since we haven't done a formal
211 release of e2fsprogs since block_iterate2 was first
212 introduced, I removed block_iterate2, and renamed
213 block_iterate3 to be block_iterate2.
215 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
216 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
217 use of block_iterate and block_iterate2 to
218 block_iterate2 with the new prototype for the
219 interator function. (using blkcnt_t forr blockcount)
221 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
223 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
224 s_prealloc_blocks, s_prealloc_dir_blocks). Added
225 conditional defines of new features COMPAT_DIR_PREALLOC,
226 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
227 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
228 the library to declare that we support COMPAT_DIR_PREALLOC,
229 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
231 * fileio.c: Rename function ext2fs_file_llseek to be
232 ext2fs_file_lseek, which is more accurate.
234 * block.c: Add new function ext2fs_block_iterate3 which calls
235 the iterator function with the blockcount argument of
236 type blkcnt_t. This version of the function is
237 allowed to handle large files; the other fucntions are
240 * ext2fs.h: Add new type blkcnt_t
242 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
244 * block.c (ext2fs_block_iterate2): Fix bug where the block count
245 field wasn't getting correctly incremented for sparse
246 files when the indirect or doubly-indirect block
247 specified in the inode was zero.
249 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
251 * unlink.c (unlink_proc):
252 * lookup.c (lookup_proc):
253 * link.c (link_proc):
254 * get_pathname.c (get_pathname_proc):
255 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
256 from dirent->name_len, so it can be used for other
259 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
260 and indicate that we have support for this incompatible
263 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
265 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
267 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
269 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
270 number of directories when the block group information is
273 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
275 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
276 inode table is missing so that we catch the case where the
277 first block group is missing.
279 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
282 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
284 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
286 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
288 * test_io.c (test_flush): Add a debugging printf when the flush
291 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
292 read in, return right away.
294 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
296 * bitops.h: Don't try to do i386 inline asm functions if the
299 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
300 instead of linux/types.h, and e2_bitops.h instead of
303 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
306 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
308 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
309 so that we don't need to call get_next_blockgroup() the
310 first time around. Saves a bit of time, and prevents us
311 from needing to assign -1 to current_group (which is an
314 * icount.c (insert_icount_el): Cast the estimated number of inodes
315 from a float to an ino_t.
317 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

327 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
328 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
329 defined, then assume all of the
330 ext2-specific header files are in a flat directory.
332 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
333 all assignments from void * to be compatible with C++.

337 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
338 make sure the contents of the disk are flushed to disk.
340 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
342 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
343 avoid C++ namespace clash.
345 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
346 avoid C++ namespace clash.
348 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
349 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
350 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
351 unlink.c: Change private to be priv_data (to avoid C++
354 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
356 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
357 paranoid about validating the directory counts from the
358 block group information.
360 * all files: Don't include stdlib.h anymore; include it in
361 ext2_fs.h, since that file requires stdlib.h
363 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
365 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
366 bitmap is loaded, and return an error if it is not.
367 (expand_dir_proc): Only use ext2fs_write_dir_block when
368 writing a directory block, not when writing out a fresh
371 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
373 * Makefile.in, tst_getsize.c: Added new file which is used to test

393 * Rename new error codes to _ET_ in them for consistency.
395 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
397 * [all files, basically]: Added definition of ext2fs_get_mem,

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

455 * inode.c (ext2fs_check_directory): Add support for the callback
456 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
458 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
460 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
461 padding of the bitmap to be all one's.
463 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
465 * llseek.c: Added missing semicolon to glibc fixup declaration of
468 * bmove.c: Add #include of errno.h
470 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
472 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
473 added a new field to the io_channel (app_data).
475 * io.h: Add a new element to the io_channel structure, app_data.
477 * initialize.c, openfs.c: Set io->app_data to point at the
480 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
482 * io.h: Change the prototype of ext2fs_llseek() to use int's
483 instead of unsigned int's.
485 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
486 to make life easer for GNU Libc 2.
488 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
489 filesystem has its bitmaps stored as 32-bit words with bit
490 0 as the LSB of each word. Thus a bitmap with only bit 0
491 set would be, as a string of bytes, 00 00 00 01 00 ... To
492 cope with this, we byte-reverse each word of a bitmap if
493 we have a big-endian filesystem, that is, if we are *not*
494 byte-swapping other word-sized numbers.
496 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

563 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
565 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
566 is zero, then return EXT2_IO_LLSEEK_FAILED.
568 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
570 * Release of E2fsprogs 1.11
572 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

575 the number of directory blocks in dblist.
577 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
579 * unix_io.c (unix_flush): Make the io_channel flush function do a
580 fsync to flush the kernel buffers to disk.
582 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
584 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
585 current inode number wasn't being set by the
586 goto_blockgroup function.
588 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
590 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
591 of blocks which need to be moved, and moves those blocks
592 to another location in the filesystem.
594 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
595 bitmap, make sure all of the new parts of the bitmap are
598 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
600 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
601 wasn't being returned to the caller.
603 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
604 ext2fs_allocate_group_table() which sets the group tables
605 for a particular block group. The relevant code was
606 factored out of ext2fs_allocate_tables().
608 * dblist.c (make_dblist): Adjust the initial size of the directory
609 block list to be a bit more realistic (ten plus twice the
610 number of directories in the filesystem).
612 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
614 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
615 ext2fs_badblocks_list_test would test the list (and exceed
616 array boundaries) if there were no bad blocks on the bad
617 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
619 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
621 * Release of E2fsprogs version 1.10
623 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
625 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
626 inode and block bitmaps based on the RAID 0 stride
627 parameter (which is passed by mke2fs).
629 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
630 mke2fs to communicate the stride length to
631 ext2fs_allocate_tables()
633 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
635 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
636 systems. (We can't assume that the new filesystem types
639 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
641 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
642 allocate the inode and block bitmaps inside block group at
645 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
647 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
648 filesystem has no free blocks, ext2fs_new_block would loop
651 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
653 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
654 free if refcount goes to zero.
656 * inode.c (create_icache): Initialize refcount to 1.
658 * ext2fsP.h: Added refcount to ext2_inode_cache
660 * dblist.c (ext2fs_copy_dblist): New function to copy a directory

670 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
672 (unix_close, test_close): Decrement the refcount and only
673 close the io_channel if the refcount goes to 0.
675 * io.h: Add refcount to the io_channel structure. Add new macro
676 interface io_channel_bumpcount() to bump the refcount.
678 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
680 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
681 cache in the filesystem handle, instead of the inode cache
682 in a static variable.
684 * freefs.c: Added static function to free the inode cache (called by
687 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
689 * ext2fs.h: Added pointer to the inode_cache structure.
691 * block.c (block_iterate_ind, block_iterate_dind,
692 block_iterate_tind): If there are holes in the indirect,
693 doubly indirect, or triply indirect blocks, increment the
694 block count field automatically.
696 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
698 * Release of E2fsprogs version 1.09
700 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
702 * version.c (ext2fs_parse_version_string): Check the passed in
703 version string (instead of the hard-coded one).
705 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
706 greater filesystem size, clamp it to prevent allocating a
707 block or inode bitmap beyond the filesystem.
709 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
710 overhead calculation was accidentally removed.
712 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
714 * Release of E2fsprogs version 1.08
716 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
718 * dblist.c (ext2fs_set_dir_block): New function which sets the
719 block of a dblist entry, given the directory inode and
722 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
724 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
725 inode bitmaps at staggered locations across the block
726 groups, to avoid concentrating the bitmaps on a small
727 number of disks when using striped RAID arrays.
729 * initialize.c (ext2fs_initialize): By default, choose the maximum
730 possible number of blocks per group (based on the size of
731 the bitmaps in the blocksize).
733 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
735 * initialize.c (ext2fs_initialize): Add support for
736 EXT2_COMPAT_SPARSE_SUPER feature.
738 * closefs.c (ext2fs_bg_has_super): New function to determine
739 whether or a particular block group should have a
740 superblock and block group descriptor. Used for the
741 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
742 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
743 or not the superblock should be written out for the block
746 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
747 for sparse duplicate superblocks.
749 * version.c (ext2fs_get_library_version): New function which
750 returns the library version.
752 * version.c (ext2fs_parse_version_string): New function which
753 parses a version string and returns a version number,
754 so application programs can compare version numbers as
757 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
759 * icount.c (ext2fs_create_icount): Change function so that it also
760 takes a new argument which contains a "hint" icount
761 structure. This "hint" icount allows the create function
762 to set up the sorted list in advance. This reduces
763 significantly the amount of data moving needed to insert
764 these inodes into the list later.
766 * icount.c (ext2fs_icount_validate): New function which validates
767 that the icount structure's rep invariant.
769 * icount.c (get_icount_el): Completely revamped implementation
770 to subsume put_icount_el(). Put_icount_el() used to
771 use an O(N) implementation to insert in the middle
772 of the icount list. It now uses a O(ln N) to search
773 for where the icount should be inserted, and then uses
774 a memcpy to move the list down (instead of a for loop).
776 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
777 ext2fs_icount_increment, ext2fs_icount_decrement): Check
778 to see if the inode is within bounds; if it isn't, return
781 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
782 when a bad inode number is passed to test_generic_bitmap
783 to be EXT2FS_TEST_ERROR instead of the wrong
786 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
788 * Release of E2fsprogs version 1.07
790 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
792 * Makefile.in (ELF_VERSION): Change version to be 2.2
794 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
796 * alloc.c (ext2fs_get_free_blocks): Change routine to use
797 ext2fs_fast_test_block_bitmap_range().
799 * bitops.h (ext2fs_fast_test_block_bitmap_range,
800 ext2fs_test_block_bitmap_range: New inline functions which
801 test to see whether a contiguous range of blocks is
804 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
806 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
807 use ext2fs_badblocks_* instead of badblocks_*
809 * bb_compat.c: New file which translates between old badblocks_*()
810 names to ext2fs_badblocks_*()
812 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
813 link.c (since e2fsck doesn't use ext2fs_unlink()).
815 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
816 bitmap resizing routine moved from bitmaps.c, since e2fsck
817 doesn't need to use this function.
819 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
820 since e2fsck only needs ext2fs_lookup.
822 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
824 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
825 already set; this is needed so that programs like dump
826 which use the inode scan functions will deal with
827 filesystems that have bad blocks in the inode table.
829 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
831 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
832 Moved to ext2fsP.h, since it doesn't need to be part of
833 the public interface.
835 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
837 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
839 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
840 directory block list abstraction. (Code moved from
843 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
844 to inode.c (since no one else should be peeking inside it!)
846 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
848 * openfs.c (ext2fs_open): Check the feature set in the ext2
849 superblock, and refuse to open filesystems if they contain
850 incompatible features. (Can be overriden with the
853 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
855 * block.c (ext2fs_block_iterate2): Added new function
856 ext2fs_block_iterate2 which changes the function
857 signature of the callback function to include the
858 referencing block and offset.
860 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
861 ext2fs_inode_scan_goto_blockgroup which allows an
862 application to jump to a particular block group while
865 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
867 * dirblock.c: Include string.h, since we use memcpy().
869 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
871 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
872 a long not an int; this doesn't matter on i386 machines,
873 but it does on Alpha's.
875 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
877 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
878 table pointer is NULL, then return an error indicating
879 that the inode table is missing.
880 (get_next_blockgroup, get_next_blocks,
881 ext2fs_get_next_inode): Don't treat a missing inode table
882 as permanent error. Return MISSING_INODE_TABLE, but as an
883 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
885 * rw_bitmaps.c (ext2fs_write_block_bitmap,
886 ext2fs_write_inode_bitmap): If the inode or block bitmap
887 block is zero, then don't write out the inode or block
888 bitmap. The idea here is to avoid stomping on the
890 (read_bitmaps): If the inode or block bitmap block is
891 zero, then fill in that portion of the inode or block
892 bitmap with all zeros.
894 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
895 blocks in inode table when the inode table size is
896 non-standard (and can therefore span blocks).
898 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
900 * alloc.c (ext2fs_new_block): Fix fencepost error in
901 ext2fs_new_block; make sure we don't try to allocate the
902 first block beyond the end of the filesystem.
904 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
906 * inode.c (check_for_inode_bad_blocks): New function called by
907 get_next_blocks() to avoid reading in bad blocks marked in
908 fs->badblocks. Inodes located in bad blocks are returned
909 by ext2fs_get_next_inode() returns the error code
910 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
912 * alloc_tables.c (ext2fs_allocate_tables): New function which
913 performs the part of mke2fs's job of allocating the
916 * test_io.c (test_close): IO manager which is used for testing
919 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
921 * inode.c (ext2fs_get_next_inode): Separate out the function of
922 setting up for a new block group to get_next_blockgroup().
923 Separate out the function of reading in blocks of the
924 inode table to get_next_blocks().
926 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
928 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
929 blocks to the badblock list in sorted order. This allows
930 badblocks_list_test to be coded using a binary search for
933 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
935 * Release of E2fsprogs version 1.06
937 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
939 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
940 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
943 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
944 set, then only write out the master superblock.
946 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
948 * block.c (ext2fs_block_iterate): Fixed bug which caused
949 block_iterate to fail to handle HURD created filesystems;
950 it tested the inode translator field before the inode was
953 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
955 * initialize.c (ext2fs_initialize): Make sure the description for
956 the inode bitmap is set correctly.
958 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
960 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
962 * Release of E2fsprogs version 1.05
964 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
966 * initialize.c: Override the kernel's idea of default
967 checkinterval from 0 (never) to 180 days.

976 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
977 for shortcut function fs->read_inode() and fs->write_inode().
978 Added inode_cache to reduce CPU time spent in doing
981 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
984 * namei.c (ext2fs_follow_link): New function.
985 (ext2fs_namei): Extended to have support for chasing
986 symbolic links. ext2fs_namei() still returns an inode
987 which is a symbolic link. Symbolic links are only chased
988 while resolving the containing directory. To chase
989 symbolic links of the final result, use
990 ext2fs_follow_link().
992 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
994 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
996 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
997 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
999 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1001 * initialize.c (ext2fs_initialize): On systems where the byte
1002 order is not i386 compatible, set the swap_byte flag.
1004 * inode.c (inocpy_with_swap): Check to see if inode contains a
1005 fast symlink before swapping the inode block fields. This
1006 required adding a new argument to inocpy_with_swap to
1007 determine whether the mode field is in host order or not.
1009 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1011 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1012 the sparc, if EXT2_STD_BITOPS set, use the standard
1013 i386-compatible bitmask operations, instead on the
1014 non-standard native bitmask operators.
1016 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1018 * block.c (ext2fs_block_iterate): Cause block iterator to return
1019 the HURD translator block (along with everything else).
1020 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1021 iterator, then don't return any meta data blocks
1022 (including the HURD translator).
1024 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1026 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1028 * uuid.c: New file, containing UUID utility functions.
1030 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1032 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1034 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1036 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1038 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1040 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1041 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1042 that's a basic value that must be correct for the rest of
1043 the library to work.
1045 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1048 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1050 * Release of E2fsprogs version 1.04

1098 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1099 to avoid conflicts with with kernel include files. Also
1100 rename ADDR and CONST_ADDR to EXT2FS_ADDR and

1105 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1107 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1108 s_def_resuid and s_def_resgid for backwards compatibility.
1110 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

1114 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
1116 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
1119 * closefs.c: #include <string.h> to pick up memset() declaration
1121 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1123 * Makefile.in: Added support for BSD shared libraries.
1125 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1128 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1130 * unix_io.c (unix_open): Add a double check; if the passed in name
1131 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1133 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1135 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

1157 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1158 Move these functions to freefs.c.
1160 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1161 descriptors shadow memory to keep purify quiet. (This
1162 also has the nice benefit that the unused portion of the
1163 shadow descriptors are zeroed out.)
1165 * dirblock.c (ext2fs_write_dir_block): We need to use
1166 dirent->rec_len *before* it's byteswapped to find the
1167 location of the next directory structure!
1169 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1170 cause ext2fs_new_inode to loop infinitely if we're trying
1171 to allocate an inode in group #0 and there are no free
1172 inodes at all in the system.
1174 * closefs.c: #include <errno.h> if it exists.
1176 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1178 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1192 to read/write the directory block.
1194 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1195 file containing functions for reading and writing
1196 directory blocks (byte swapping if necesssary)
1198 * block.c (block_iterate_ind, block_iterate_dind,
1199 block_iterate_tind): Byte swap the block addresses if
1200 EXT2_SWAP_BYTES is set (and swap them back before writing
1203 * inode.c (inocpy_with_swap): New function.
1204 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1205 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1207 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1208 the superblock and group descriptors before writing it out.
1210 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1211 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1212 and group descriptors.
1214 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1215 to desp ext2 filesystem structures.
1217 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1218 supplied by Pete A. Zaitcev so that the C language
1219 versions of these functions are more portable. They will
1220 now work on both little and big endian systems, and the
1221 assumption that 32-bit integers are used is gone.
1223 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1224 doing byte swapping.
1226 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1227 byte swapping should take place.
1229 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

1238 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1240 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1241 if the magic number is correct, it will be allocated.
1243 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1245 * block.c (block_iterate_ind, block_iterate_dind,
1246 block_iterate_tind): Don't recompute block_nr each loop;
1247 just increment it! Factor check of BLOCK_FLAG_APPEND out
1248 of the loop. Factor mask of BLOCK_CHANGED into changed
1249 variable out of the loop. (block_iterate_ind, in
1250 particular, gets called a lot, so every little
1251 optimization helps.)
1253 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1255 * block.c (block_iterate_ind, block_iterate_dind,

1257 block_iterate_ind and company.
1259 * bitops.h (ext2fs_fast_mark_block_bitmap,
1260 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1261 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1262 ext2fs_fast_test_inode_bitmap): Add fast version of these
1263 functions, which don't do range checking.
1265 * bitops.h (ext2fs_get_block_bitmap_start,
1266 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1267 ext2fs_get_inode_bitmap_end): Add new accessor functions
1268 which return the start and end points of the bitmaps.
1270 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1272 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1273 instead of llseek. The errno if the offset is too large
1274 and lseek is not supported should be EINVAL, not -EINVAL.
1276 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1278 * Makefile.in: Added support for ELF shared libraries.
1279 Fixed typos in the compilation rules.
1280 (distclean): Added Makefile.
1282 * llseek.c (llseek): New function, if llseek() does not exist in the
1284 (ext2_llseek): Changed to call llseek().
1286 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1288 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1290 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1292 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1294 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1295 the S_*, which are normally defined in <sys/stat.h>. This
1296 allows us to compile e2fsprogs on a non-Linux system,
1297 which may have a different value for S_IFDIR.
1299 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1301 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1302 this is a user-mode application!
1304 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1306 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1307 __linux__ so that non-linux systems won't see it.
1309 * alloc.c: Include <errno.h> if possible.
1310 * badblocks.c: Ditto.
1311 * bb_inode.c: Ditto.
1314 * expanddir.c: Ditto.
1315 * get_pathname.c: Ditto.
1316 * initialize.c: Ditto.
1323 * rw_bitmaps.c: Ditto.
1326 * Makefile.in: Rewritten to conform to GNU coding standards and
1327 support separate compilation directories.
1329 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1331 * initialize.c (ext2fs_initialize): Don't allow more than one
1332 bitmaps's worth of inodes in a group.
1334 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1336 * llseek.c (ext2_llseek): Added error checking to the llseek()
1337 compat code to protect against overflow. This only
1338 applies to 1.0 and early 1.1 kernels, which don't support
1339 the llseek() system call.
1341 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1343 * unix_io.c (unix_open): Initialize the read_error and write_error
1344 io_channel pointers to be null.
1346 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1347 found, clear it but don't try to update the filesystem
1348 accounting information, since that's hopeless anyway.
1350 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1351 bloblock_iterate_tind): Check to see if the indirect blocks are
1352 valid before trying to read them.
1354 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1355 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1357 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1358 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1359 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1360 illegal block or inode number is passed in, return instead
1361 of trying to test, set, or clear the bit.
1363 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1365 * Makefile: Added a dummy install target in case shared libraries
1368 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1370 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

1375 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1376 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1377 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1378 ext2fs_free_block_bitmap): Add magic number checking for
1379 the inode and block bitmaps.
1381 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1382 magic number for a block bitmap instead of an inode bitmap.
1384 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1385 magic number checking for the inode_scan structure.
1387 * badblocks.c (badblocks_list_free, badblocks_list_add,
1388 badblocks_list_test, badblocks_list_iterate_begin,
1389 badblocks_list_iterate, badblocks_list_iterate_end): Add
1390 magic number checking for the badblocks_list and
1391 badblocks_iterate structures.
1393 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1394 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1395 unix_write_blk, unix_flush): Add magic number checking
1396 both for io_channel structure and unix_private_data
1399 * openfs.c (ext2fs_open): Add check for io_manager structure's
1402 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1403 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1404 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1405 * read_bb.c (ext2fs_read_bb_inode):
1406 * read_bb_file.c (ext2fs_read_bb_FILE):

1417 ext2fs_allocate_block_bitmap):
1418 * bb_inode.c (ext2fs_update_bb_inode):
1419 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):

1421 * closefs.c (ext2fs_close, ext2fs_flush):
1422 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1427 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1428 openfs.c into its own file.
1430 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1431 structure magic numbers.
1433 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1434 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1435 someone uses the -b option to specify the use of the backup
1436 superblock --- this usually means that the main superblock is
1440 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1441 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1442 revision level to the superblock.
1444 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1451 * initialize.c: Completely revamped the inode and block bitmap
1452 structures, so that they can be better chance of being extensible
1453 in a shared library. They are now their own type, instead of
1454 being a char *. Also, the function signatures of
1455 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1456 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1457 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1458 changed to eliminate the ext2_filsys argument, since it is no
1461 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1463 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1464 system call if available.
1466 * llseek.c: new file. This is the stub calling the llseek system
1467 call which allows supports for 2GB+ file systems.
1469 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1470 the creator operating system.
1472 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1474 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1475 the group descriptor statistics in addition to everything else.
1476 This relieves mke2fs of the responsibility of doing it.
1478 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1479 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1480 not the generic C function equivalents should be included or not.
1482 * openfs.c (ext2fs_open): If a superblock is specified, then use
1483 the backup group descriptors that go along with this superblock,
1484 instead of using the primary group descriptors. This allows
1485 e2fsck to recover filesystems where the primary group descriptors
