1 1999-10-22 <tytso@valinux.com>
3 * Release of E2fsprogs 1.16
5 1999-10-22 <tytso@valinux.com>
7 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
9 * link.c (ext2fs_link): This call now uses the low three bits of
10 the flags parameter to pass the directory filetype
11 information; it will set the directory entry FILETYPE
12 information if the filesystem supports it.
14 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
15 option is set, then create the '.' and '..' entries with
16 the filetype set to EXT2_FT_DIR.
18 1999-09-24 <tytso@valinux.com>
20 * nt_io.c: New file which supports I/O under Windows NT.
22 1999-09-07 <tytso@valinux.com>
24 * ext2fs.h: Add new fields for journalling and define new
25 feature bits used by newer filesystems: IMAGIC_INODES,
28 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
29 we update the inode block count and size files so that the
30 block count field is updated correctly when we create an
33 1999-07-18 Theodore Ts'o <tytso@valinux.com>
35 * Release of E2fsprogs 1.15
37 1999-06-23 <tytso@valinux.com>
39 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
40 kernels that use i_generation instead of i_version. Patch
41 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
43 1999-06-21 <tytso@valinux.com>
45 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
46 directory entry before calling the callback function.
47 This should prevent some core dumps of insufficiently
48 paranoid callback functions.
50 1999-05-29 <tytso@rsts-11.mit.edu>
52 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
54 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
55 that we don't handle writing yet (we do). Fixed bug where
56 we weren't allocating a big enough buffer for ext2_bmap.
58 1999-05-03 <tytso@rsts-11.mit.edu>
60 * openfs.c (ext2fs_open): Check to make sure that the number of
61 blocks per group is not zero --- if so, it must be a bad
64 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
66 * Release of E2fsprogs 1.14
68 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
70 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
71 the inode number is zero; if it's zero, return
72 EXT2_ET_BAD_INODE_NUM.
74 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
76 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
77 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
80 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
82 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
83 non-Linux case to use EINVAL by default, unless it isn't
84 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
87 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
89 * Release of E2fsprogs 1.13
91 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
93 * Makefile.in: Updated dependencies.
95 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
97 * initialize.c (ext2fs_initialize): Make sure that we allocate
98 enough inodes so that we can make a valid filesystem.
100 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
102 * rw_bitmaps.c: Fixed signed/unsigned warnings.
104 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
105 function declaration.
107 * dblist.c (make_dblist): Add safety check in case the dblist
108 pointer passed in is null (in which case, assign it to
109 fs->dblist). Fixed some signed/unsigned warnings.
111 * bmap.c: Make addr_per_block be of type blk_t to avoid
112 signed/unsigned warnings.
114 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
115 function declaration.
117 * get_pathname.c (get_pathname_proc): Use return value from
118 ext2fs_get_mem, instead of checking if &gp->name is
121 * dir_iterate.c (ext2fs_process_dir_block):
122 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
123 from the function declaration.
125 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
126 return the error directly instead of jumping to the
127 cleanup routine, since we don't need to do any cleanup.
129 * alloc_table.c (ext2fs_allocate_group_table): Make this
130 function take a dgrp_t for its group argument.
132 * ext2fs.h: Make dgrp_t an __u32 type, and make
133 fs->desc_group_count be of type dgrp_t.
135 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
137 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
138 than 10 blocks when we need to expand the size of the
141 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
143 * Release of E2fsprogs 1.12
145 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
147 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
148 appropriate for all of the block group copies, so that
149 it's clear where the beginning of the filesystem is on the
150 disk. (For when the partition table gets scrod.)
152 * ext2fs.h: Change the name of the feature from
153 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
154 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
156 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
158 * inode.c (get_next_blockgroup): Fix bug where if
159 get_next_blockgroup() is called early because of a missing
160 inode table in a block group, the current_inode counter
161 wasn't incremented correctly.
163 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
165 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
166 against a completely trashed bad block inode.
168 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
170 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
171 the stride length hits a bad value, we retry the block
172 allocation starting at the beginning of the block group.
174 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
175 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
176 e2_blkcnt_t to avoid collision with LFS API.
178 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
180 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
181 way that avoids overflows on disk sizes greater than 4GB.
183 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
185 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
186 return type for comparison functions for qsort.
188 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
191 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
193 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
196 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
197 evade a potential problem with glibc's header files trying
198 to spike out linux/types.h.
200 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
201 include the old size of the memory, which is needed for
202 some braindamaged memory allocation systems that don't
205 * badblocks.c (ext2fs_badblocks_list_add):
206 bb_inode.c (clear_bad_block_proc):

211 pass the old size of the memory to be resized to
214 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
216 * Makefile.in: Change to use new installation directory variables
217 convention. Fix uninstall rules to take $(DESTDIR) into
220 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
222 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
223 with 32 bit longs, then we need to manually define __s64
224 and __u64, since the current kernel header files don't
225 define these if __STRICT_ANSI__ is defined. This is a
226 problem if we are compiling with full GCC warnings, since
227 we do need 64 bit support.
229 * Makefile.in (OBJS): Remove bmove.o from files to be built,
230 since we're not using ext2fs_move_blocks() and there
231 is some question as to its usefulness in its current
234 * bmap.c (block_bmap): Remove unused function.
236 * bmove.c (process_block): Fix -Wall warning.
238 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
240 * block.c (ext2fs_block_iterate3): Make the ref_offset field
241 contain the offset into the inode.i_blocks array when
242 ref_block is zero. Since we haven't done a formal
243 release of e2fsprogs since block_iterate2 was first
244 introduced, I removed block_iterate2, and renamed
245 block_iterate3 to be block_iterate2.
247 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
248 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
249 use of block_iterate and block_iterate2 to
250 block_iterate2 with the new prototype for the
251 interator function. (using blkcnt_t forr blockcount)
253 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
255 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
256 s_prealloc_blocks, s_prealloc_dir_blocks). Added
257 conditional defines of new features COMPAT_DIR_PREALLOC,
258 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
259 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
260 the library to declare that we support COMPAT_DIR_PREALLOC,
261 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
263 * fileio.c: Rename function ext2fs_file_llseek to be
264 ext2fs_file_lseek, which is more accurate.
266 * block.c: Add new function ext2fs_block_iterate3 which calls
267 the iterator function with the blockcount argument of
268 type blkcnt_t. This version of the function is
269 allowed to handle large files; the other fucntions are
272 * ext2fs.h: Add new type blkcnt_t
274 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
276 * block.c (ext2fs_block_iterate2): Fix bug where the block count
277 field wasn't getting correctly incremented for sparse
278 files when the indirect or doubly-indirect block
279 specified in the inode was zero.
281 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
283 * unlink.c (unlink_proc):
284 * lookup.c (lookup_proc):
285 * link.c (link_proc):
286 * get_pathname.c (get_pathname_proc):
287 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
288 from dirent->name_len, so it can be used for other
291 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
292 and indicate that we have support for this incompatible
295 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
297 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
299 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
301 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
302 number of directories when the block group information is
305 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
307 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
308 inode table is missing so that we catch the case where the
309 first block group is missing.
311 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
314 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
316 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
318 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
320 * test_io.c (test_flush): Add a debugging printf when the flush
323 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
324 read in, return right away.
326 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
328 * bitops.h: Don't try to do i386 inline asm functions if the
331 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
332 instead of linux/types.h, and e2_bitops.h instead of
335 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
338 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
340 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
341 so that we don't need to call get_next_blockgroup() the
342 first time around. Saves a bit of time, and prevents us
343 from needing to assign -1 to current_group (which is an
346 * icount.c (insert_icount_el): Cast the estimated number of inodes
347 from a float to an ino_t.
349 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

359 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
360 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
361 defined, then assume all of the
362 ext2-specific header files are in a flat directory.
364 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
365 all assignments from void * to be compatible with C++.
367 Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
369 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
370 make sure the contents of the disk are flushed to disk.
372 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
374 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
375 avoid C++ namespace clash.
377 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
378 avoid C++ namespace clash.
380 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
381 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
382 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
383 unlink.c: Change private to be priv_data (to avoid C++
386 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
388 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
389 paranoid about validating the directory counts from the
390 block group information.
392 * all files: Don't include stdlib.h anymore; include it in
393 ext2_fs.h, since that file requires stdlib.h
395 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
397 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
398 bitmap is loaded, and return an error if it is not.
399 (expand_dir_proc): Only use ext2fs_write_dir_block when
400 writing a directory block, not when writing out a fresh
403 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
405 * Makefile.in, tst_getsize.c: Added new file which is used to test

418 Fri Oct 31 12:16:52 1997 <tytso@EDT.MIT.EDU>
420 * bitops.c (ext2fs_warn_bitmap, ext2fs_warn_bitmap2): Don't call

423 Thu Oct 30 11:33:57 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
425 * Rename new error codes to _ET_ in them for consistency.
427 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
429 * [all files, basically]: Added definition of ext2fs_get_mem,
430 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
431 changed all library routines to use these wrapper functions.

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

474 * Rename io.h to be ext2_io.h (avoid namespace collisions)
476 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H

485 Mon Sep 15 11:45:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
487 * inode.c (ext2fs_check_directory): Add support for the callback
488 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
490 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
492 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
493 padding of the bitmap to be all one's.
495 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
497 * llseek.c: Added missing semicolon to glibc fixup declaration of
500 * bmove.c: Add #include of errno.h
502 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
504 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
505 added a new field to the io_channel (app_data).
507 * io.h: Add a new element to the io_channel structure, app_data.
509 * initialize.c, openfs.c: Set io->app_data to point at the
512 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
514 * io.h: Change the prototype of ext2fs_llseek() to use int's
515 instead of unsigned int's.
517 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
518 to make life easer for GNU Libc 2.
520 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
521 filesystem has its bitmaps stored as 32-bit words with bit
522 0 as the LSB of each word. Thus a bitmap with only bit 0
523 set would be, as a string of bytes, 00 00 00 01 00 ... To
524 cope with this, we byte-reverse each word of a bitmap if
525 we have a big-endian filesystem, that is, if we are *not*
526 byte-swapping other word-sized numbers.
528 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

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

607 the number of directory blocks in dblist.
609 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
611 * unix_io.c (unix_flush): Make the io_channel flush function do a
612 fsync to flush the kernel buffers to disk.
614 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
616 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
617 current inode number wasn't being set by the
618 goto_blockgroup function.
620 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
622 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
623 of blocks which need to be moved, and moves those blocks
624 to another location in the filesystem.
626 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
627 bitmap, make sure all of the new parts of the bitmap are
630 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
632 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
633 wasn't being returned to the caller.
635 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
636 ext2fs_allocate_group_table() which sets the group tables
637 for a particular block group. The relevant code was
638 factored out of ext2fs_allocate_tables().
640 * dblist.c (make_dblist): Adjust the initial size of the directory
641 block list to be a bit more realistic (ten plus twice the
642 number of directories in the filesystem).
644 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
646 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
647 ext2fs_badblocks_list_test would test the list (and exceed
648 array boundaries) if there were no bad blocks on the bad
649 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
651 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
653 * Release of E2fsprogs version 1.10
655 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
657 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
658 inode and block bitmaps based on the RAID 0 stride
659 parameter (which is passed by mke2fs).
661 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
662 mke2fs to communicate the stride length to
663 ext2fs_allocate_tables()
665 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
667 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
668 systems. (We can't assume that the new filesystem types
671 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
673 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we

683 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
685 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only

702 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
704 (unix_close, test_close): Decrement the refcount and only
705 close the io_channel if the refcount goes to 0.
707 * io.h: Add refcount to the io_channel structure. Add new macro
708 interface io_channel_bumpcount() to bump the refcount.
710 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
712 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
713 cache in the filesystem handle, instead of the inode cache
714 in a static variable.
716 * freefs.c: Added static function to free the inode cache (called by
719 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
721 * ext2fs.h: Added pointer to the inode_cache structure.
723 * block.c (block_iterate_ind, block_iterate_dind,
724 block_iterate_tind): If there are holes in the indirect,
725 doubly indirect, or triply indirect blocks, increment the
726 block count field automatically.
728 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
730 * Release of E2fsprogs version 1.09
732 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
734 * version.c (ext2fs_parse_version_string): Check the passed in
735 version string (instead of the hard-coded one).
737 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
738 greater filesystem size, clamp it to prevent allocating a
739 block or inode bitmap beyond the filesystem.
741 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
742 overhead calculation was accidentally removed.
744 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
746 * Release of E2fsprogs version 1.08
748 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
750 * dblist.c (ext2fs_set_dir_block): New function which sets the
751 block of a dblist entry, given the directory inode and
754 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
756 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
757 inode bitmaps at staggered locations across the block
758 groups, to avoid concentrating the bitmaps on a small
759 number of disks when using striped RAID arrays.
761 * initialize.c (ext2fs_initialize): By default, choose the maximum
762 possible number of blocks per group (based on the size of
763 the bitmaps in the blocksize).
765 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
767 * initialize.c (ext2fs_initialize): Add support for
768 EXT2_COMPAT_SPARSE_SUPER feature.
770 * closefs.c (ext2fs_bg_has_super): New function to determine
771 whether or a particular block group should have a
772 superblock and block group descriptor. Used for the
773 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
774 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
775 or not the superblock should be written out for the block
778 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
779 for sparse duplicate superblocks.
781 * version.c (ext2fs_get_library_version): New function which
782 returns the library version.
784 * version.c (ext2fs_parse_version_string): New function which
785 parses a version string and returns a version number,
786 so application programs can compare version numbers as
789 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
791 * icount.c (ext2fs_create_icount): Change function so that it also
792 takes a new argument which contains a "hint" icount
793 structure. This "hint" icount allows the create function
794 to set up the sorted list in advance. This reduces
795 significantly the amount of data moving needed to insert
796 these inodes into the list later.
798 * icount.c (ext2fs_icount_validate): New function which validates
799 that the icount structure's rep invariant.
801 * icount.c (get_icount_el): Completely revamped implementation
802 to subsume put_icount_el(). Put_icount_el() used to
803 use an O(N) implementation to insert in the middle
804 of the icount list. It now uses a O(ln N) to search
805 for where the icount should be inserted, and then uses
806 a memcpy to move the list down (instead of a for loop).
808 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
809 ext2fs_icount_increment, ext2fs_icount_decrement): Check
810 to see if the inode is within bounds; if it isn't, return
813 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
814 when a bad inode number is passed to test_generic_bitmap
815 to be EXT2FS_TEST_ERROR instead of the wrong
818 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
820 * Release of E2fsprogs version 1.07
822 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
824 * Makefile.in (ELF_VERSION): Change version to be 2.2
826 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
828 * alloc.c (ext2fs_get_free_blocks): Change routine to use
829 ext2fs_fast_test_block_bitmap_range().
831 * bitops.h (ext2fs_fast_test_block_bitmap_range,
832 ext2fs_test_block_bitmap_range: New inline functions which
833 test to see whether a contiguous range of blocks is
836 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
838 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
839 use ext2fs_badblocks_* instead of badblocks_*
841 * bb_compat.c: New file which translates between old badblocks_*()
842 names to ext2fs_badblocks_*()
844 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
845 link.c (since e2fsck doesn't use ext2fs_unlink()).
847 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
848 bitmap resizing routine moved from bitmaps.c, since e2fsck
849 doesn't need to use this function.
851 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
852 since e2fsck only needs ext2fs_lookup.
854 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
856 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
857 already set; this is needed so that programs like dump
858 which use the inode scan functions will deal with
859 filesystems that have bad blocks in the inode table.
861 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
863 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
864 Moved to ext2fsP.h, since it doesn't need to be part of
865 the public interface.
867 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
869 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
871 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
872 directory block list abstraction. (Code moved from
875 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
876 to inode.c (since no one else should be peeking inside it!)
878 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
880 * openfs.c (ext2fs_open): Check the feature set in the ext2
881 superblock, and refuse to open filesystems if they contain
882 incompatible features. (Can be overriden with the
885 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
887 * block.c (ext2fs_block_iterate2): Added new function
888 ext2fs_block_iterate2 which changes the function
889 signature of the callback function to include the
890 referencing block and offset.
892 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
893 ext2fs_inode_scan_goto_blockgroup which allows an
894 application to jump to a particular block group while
897 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
899 * dirblock.c: Include string.h, since we use memcpy().
901 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
903 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
904 a long not an int; this doesn't matter on i386 machines,
905 but it does on Alpha's.
907 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
909 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
910 table pointer is NULL, then return an error indicating
911 that the inode table is missing.
912 (get_next_blockgroup, get_next_blocks,
913 ext2fs_get_next_inode): Don't treat a missing inode table
914 as permanent error. Return MISSING_INODE_TABLE, but as an
915 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
917 * rw_bitmaps.c (ext2fs_write_block_bitmap,
918 ext2fs_write_inode_bitmap): If the inode or block bitmap
919 block is zero, then don't write out the inode or block
920 bitmap. The idea here is to avoid stomping on the
922 (read_bitmaps): If the inode or block bitmap block is
923 zero, then fill in that portion of the inode or block
924 bitmap with all zeros.
926 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
927 blocks in inode table when the inode table size is
928 non-standard (and can therefore span blocks).
930 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
932 * alloc.c (ext2fs_new_block): Fix fencepost error in
933 ext2fs_new_block; make sure we don't try to allocate the
934 first block beyond the end of the filesystem.
936 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
938 * inode.c (check_for_inode_bad_blocks): New function called by
939 get_next_blocks() to avoid reading in bad blocks marked in
940 fs->badblocks. Inodes located in bad blocks are returned
941 by ext2fs_get_next_inode() returns the error code
942 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
944 * alloc_tables.c (ext2fs_allocate_tables): New function which
945 performs the part of mke2fs's job of allocating the
948 * test_io.c (test_close): IO manager which is used for testing
951 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
953 * inode.c (ext2fs_get_next_inode): Separate out the function of
954 setting up for a new block group to get_next_blockgroup().
955 Separate out the function of reading in blocks of the
956 inode table to get_next_blocks().
958 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
960 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
961 blocks to the badblock list in sorted order. This allows
962 badblocks_list_test to be coded using a binary search for
965 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
967 * Release of E2fsprogs version 1.06
969 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
971 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
972 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
975 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
976 set, then only write out the master superblock.
978 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
980 * block.c (ext2fs_block_iterate): Fixed bug which caused
981 block_iterate to fail to handle HURD created filesystems;
982 it tested the inode translator field before the inode was
985 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
987 * initialize.c (ext2fs_initialize): Make sure the description for
988 the inode bitmap is set correctly.
990 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
992 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
994 * Release of E2fsprogs version 1.05
996 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
998 * initialize.c: Override the kernel's idea of default
999 checkinterval from 0 (never) to 180 days.

1013 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
1016 * namei.c (ext2fs_follow_link): New function.
1017 (ext2fs_namei): Extended to have support for chasing
1018 symbolic links. ext2fs_namei() still returns an inode
1019 which is a symbolic link. Symbolic links are only chased
1020 while resolving the containing directory. To chase
1021 symbolic links of the final result, use
1022 ext2fs_follow_link().
1024 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1026 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1028 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1029 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
1031 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1033 * initialize.c (ext2fs_initialize): On systems where the byte
1034 order is not i386 compatible, set the swap_byte flag.
1036 * inode.c (inocpy_with_swap): Check to see if inode contains a
1037 fast symlink before swapping the inode block fields. This
1038 required adding a new argument to inocpy_with_swap to
1039 determine whether the mode field is in host order or not.
1041 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1043 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1044 the sparc, if EXT2_STD_BITOPS set, use the standard
1045 i386-compatible bitmask operations, instead on the
1046 non-standard native bitmask operators.
1048 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1050 * block.c (ext2fs_block_iterate): Cause block iterator to return
1051 the HURD translator block (along with everything else).
1052 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1053 iterator, then don't return any meta data blocks
1054 (including the HURD translator).
1056 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1058 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1060 * uuid.c: New file, containing UUID utility functions.
1062 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1070 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1072 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1073 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1074 that's a basic value that must be correct for the rest of
1075 the library to work.
1077 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1080 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1128 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1129 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1130 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1131 to avoid conflicts with with kernel include files. Also
1132 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1135 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1137 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1139 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1140 s_def_resuid and s_def_resgid for backwards compatibility.
1142 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

1155 * Makefile.in: Added support for BSD shared libraries.
1157 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1160 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1162 * unix_io.c (unix_open): Add a double check; if the passed in name
1163 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1165 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1167 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

1189 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1190 Move these functions to freefs.c.
1192 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1193 descriptors shadow memory to keep purify quiet. (This
1194 also has the nice benefit that the unused portion of the
1195 shadow descriptors are zeroed out.)
1197 * dirblock.c (ext2fs_write_dir_block): We need to use
1198 dirent->rec_len *before* it's byteswapped to find the
1199 location of the next directory structure!
1201 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1202 cause ext2fs_new_inode to loop infinitely if we're trying
1203 to allocate an inode in group #0 and there are no free
1204 inodes at all in the system.
1206 * closefs.c: #include <errno.h> if it exists.
1208 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1210 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1216 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1217 installation directories correctly.
1219 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1221 * namei.c (process_dir_block):
1222 * mkdir.c (ext2fs_mkdir):

1224 to read/write the directory block.
1226 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1227 file containing functions for reading and writing
1228 directory blocks (byte swapping if necesssary)
1230 * block.c (block_iterate_ind, block_iterate_dind,
1231 block_iterate_tind): Byte swap the block addresses if
1232 EXT2_SWAP_BYTES is set (and swap them back before writing
1235 * inode.c (inocpy_with_swap): New function.
1236 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1237 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1239 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1240 the superblock and group descriptors before writing it out.
1242 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1243 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1244 and group descriptors.
1246 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1247 to desp ext2 filesystem structures.
1249 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1250 supplied by Pete A. Zaitcev so that the C language
1251 versions of these functions are more portable. They will
1252 now work on both little and big endian systems, and the
1253 assumption that 32-bit integers are used is gone.
1255 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1256 doing byte swapping.
1258 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1259 byte swapping should take place.
1261 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1263 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,

1270 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1272 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1273 if the magic number is correct, it will be allocated.
1275 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1277 * block.c (block_iterate_ind, block_iterate_dind,
1278 block_iterate_tind): Don't recompute block_nr each loop;
1279 just increment it! Factor check of BLOCK_FLAG_APPEND out
1280 of the loop. Factor mask of BLOCK_CHANGED into changed
1281 variable out of the loop. (block_iterate_ind, in
1282 particular, gets called a lot, so every little
1283 optimization helps.)
1285 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1287 * block.c (block_iterate_ind, block_iterate_dind,

1289 block_iterate_ind and company.
1291 * bitops.h (ext2fs_fast_mark_block_bitmap,
1292 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1293 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1294 ext2fs_fast_test_inode_bitmap): Add fast version of these
1295 functions, which don't do range checking.
1297 * bitops.h (ext2fs_get_block_bitmap_start,
1298 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1299 ext2fs_get_inode_bitmap_end): Add new accessor functions
1300 which return the start and end points of the bitmaps.
1302 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1304 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1305 instead of llseek. The errno if the offset is too large
1306 and lseek is not supported should be EINVAL, not -EINVAL.
1308 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1310 * Makefile.in: Added support for ELF shared libraries.
1311 Fixed typos in the compilation rules.
1312 (distclean): Added Makefile.
1314 * llseek.c (llseek): New function, if llseek() does not exist in the
1316 (ext2_llseek): Changed to call llseek().
1318 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1320 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1322 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1324 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1326 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1327 the S_*, which are normally defined in <sys/stat.h>. This
1328 allows us to compile e2fsprogs on a non-Linux system,
1329 which may have a different value for S_IFDIR.
1331 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1333 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1334 this is a user-mode application!
1336 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1338 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1339 __linux__ so that non-linux systems won't see it.
1341 * alloc.c: Include <errno.h> if possible.
1342 * badblocks.c: Ditto.
1343 * bb_inode.c: Ditto.
1346 * expanddir.c: Ditto.
1347 * get_pathname.c: Ditto.
1348 * initialize.c: Ditto.
1355 * rw_bitmaps.c: Ditto.
1358 * Makefile.in: Rewritten to conform to GNU coding standards and
1359 support separate compilation directories.
1361 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1363 * initialize.c (ext2fs_initialize): Don't allow more than one
1364 bitmaps's worth of inodes in a group.
1366 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1368 * llseek.c (ext2_llseek): Added error checking to the llseek()
1369 compat code to protect against overflow. This only
1370 applies to 1.0 and early 1.1 kernels, which don't support
1371 the llseek() system call.
1373 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1375 * unix_io.c (unix_open): Initialize the read_error and write_error
1376 io_channel pointers to be null.
1378 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1379 found, clear it but don't try to update the filesystem
1380 accounting information, since that's hopeless anyway.
1382 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1383 bloblock_iterate_tind): Check to see if the indirect blocks are
1384 valid before trying to read them.

1387 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1389 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1390 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1391 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1392 illegal block or inode number is passed in, return instead
1393 of trying to test, set, or clear the bit.
1395 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1397 * Makefile: Added a dummy install target in case shared libraries
1400 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1402 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

1407 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1408 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1409 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1410 ext2fs_free_block_bitmap): Add magic number checking for
1411 the inode and block bitmaps.
1413 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1414 magic number for a block bitmap instead of an inode bitmap.
1416 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1417 magic number checking for the inode_scan structure.

1420 badblocks_list_test, badblocks_list_iterate_begin,
1421 badblocks_list_iterate, badblocks_list_iterate_end): Add
1422 magic number checking for the badblocks_list and
1423 badblocks_iterate structures.
1425 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1426 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1427 unix_write_blk, unix_flush): Add magic number checking
1428 both for io_channel structure and unix_private_data
1431 * openfs.c (ext2fs_open): Add check for io_manager structure's
1434 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1435 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1436 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1437 * read_bb.c (ext2fs_read_bb_inode):
1438 * read_bb_file.c (ext2fs_read_bb_FILE):
1439 * newdir.c (ext2fs_new_dir_block):

1447 * block.c (ext2fs_block_iterate):
1448 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1449 ext2fs_allocate_block_bitmap):
1450 * bb_inode.c (ext2fs_update_bb_inode):
1451 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1452 * check_desc.c (ext2fs_check_desc):
1453 * closefs.c (ext2fs_close, ext2fs_flush):
1454 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1459 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1460 openfs.c into its own file.
1462 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1463 structure magic numbers.
1465 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1466 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1467 someone uses the -b option to specify the use of the backup
1468 superblock --- this usually means that the main superblock is
1472 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1473 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1474 revision level to the superblock.
1476 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1483 * initialize.c: Completely revamped the inode and block bitmap
1484 structures, so that they can be better chance of being extensible
1485 in a shared library. They are now their own type, instead of
1486 being a char *. Also, the function signatures of
1487 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1488 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1489 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1490 changed to eliminate the ext2_filsys argument, since it is no
1493 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1495 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1496 system call if available.
1498 * llseek.c: new file. This is the stub calling the llseek system
1499 call which allows supports for 2GB+ file systems.
1501 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1502 the creator operating system.
1504 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1506 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1507 the group descriptor statistics in addition to everything else.
1508 This relieves mke2fs of the responsibility of doing it.
1510 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1511 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1512 not the generic C function equivalents should be included or not.
1514 * openfs.c (ext2fs_open): If a superblock is specified, then use
1515 the backup group descriptors that go along with this superblock,
1516 instead of using the primary group descriptors. This allows
1517 e2fsck to recover filesystems where the primary group descriptors
