1 2001-01-03 <tytso@snap.thunk.org>
3 * Makefile.in: Link in libe2p when creating libext2fs as a shared
4 library, since mkjournal.c now references fsetflags().
6 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
7 Dilger's changes (with fixups) to allow on-line creation
10 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
11 EXT2_FLAG_SUPER_ONLY, which the close routines to only
12 update the superblock, and not the group descriptors.
14 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
16 * ismounted.c: add ext2fs_check_mount_point() function, which will
17 optionally return the mount point of a device if mounted
19 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
21 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
22 ext2fs_add_journal_inode()
24 2001-01-01 <tytso@snap.thunk.org>
26 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
27 source (but not binary) compatibility of some users of the
28 ext2 library. They should just simply do a global search
29 and replace of struct ext2fs_sb with struct
30 ext2_super_block, and use their own private copy of
31 ext2_fs.h if they aren't already.
33 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
34 Replace use of ext2fs_sb with ext2_super_block.
36 2000-12-31 <tytso@snap.thunk.org>
38 * ext2fs.h: Cleaned up header file by removing definitions of
39 feature flags that might not have been defined in older
40 ext2 header files. Now that we're using our own
41 include/linux/ext2fs.h header file, this can never happen.
43 * jfs_dat.h: Removed old header file which is no longer needed.
45 2000-12-13 Theodore Ts'o <tytso@valinux.com>
47 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
48 by Andreas Dilger to update the filesystem revision to
51 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
54 2000-12-09 <tytso@snap.thunk.org>
56 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
57 ext2fs_add_journal_device): Add a new argument to the APIs
58 of these function, which is a flags word. This is used to
59 allow the creation of a V1 superblock for those folks who
60 are using ext3 0.3b in production. Note, the user-land
61 interface for getting at this flag won't be documented, as
62 the V1 superblock is deprecated.
64 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
65 which creates a V2 superblock instead of a V1 superblock.
67 2000-11-21 <tytso@snap.thunk.org>
69 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
70 out by Andreas Dilger.
72 2000-11-05 <tytso@snap.thunk.org>
74 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
75 ext2_fs.h, Makefile.in: New file that has routines that
76 save ext2fs metadata to a file.
78 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
80 * e2image.h: New file which defines the file format for the ext2
81 image file. (Saved copy of ext2 metadata to a file as a
82 saving throw against worst-case damage.)
84 2000-11-01 <tytso@snap.thunk.org>
86 * inode.c (ext2fs_flush_icache): Add new function
87 ext2fs_flush_icache() which flushes the internal inode
88 cache. Applications which modify the inode table blocks
89 directly must call this function.
91 2000-10-26 <tytso@snap.thunk.org>
93 * mkjournal.c: Add #include of netinet/in.h, since Solaris
94 requires it for ntohl().
96 * ext2_io.h (io_channel_write_byte): Add new interface to allow
97 callers to write specific byte ranges. This is an
98 optional interface, which not all IO channels may
101 * unix_io.c (unix_write_byte):
102 * test_io.c (test_write_byte): Add implementation of the
105 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
106 function which writes the primary superblock. If the IO
107 channel supports writing raw bytes directly, only fields
108 which were modified are written to the disk. This makes
109 it safe(r) to use utilities like tune2fs on a mounted
112 * freefs.c (ext2fs_free): Free the original superblock if it is
115 * openfs.c (ext2fs_open): Store a copy of the original superblock
118 * ext2fs.h: Add a field to store the original superblock in the
119 ext2 context structure.
121 2000-10-24 <tytso@snap.thunk.org>
123 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
124 don't need to use llseek).
126 2000-10-24 <tytso@valinux.com>
128 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
129 creating an ext3 journal on a filesystem.
131 2000-08-21 <tytso@valinux.com>
133 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
135 2000-08-22 <tytso@valinux.com>
137 * unix_io.c: Make massive changes to support a multiple block
138 writethrough cacheing.
140 * ext2_io.h: Added flags field to the io_channel structure.
142 2000-08-19 <tytso@valinux.com>
144 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
145 provides the function ext2fs_find_block_device(). This
146 function returns the pathname to a block device, given its
149 2000-07-13 <tytso@valinux.com>
151 * Release of E2fsprogs 1.19
153 2000-07-07 Theodore Ts'o <tytso@valinux.com>
155 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
156 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
157 list of filesystem flags supported by the library.
159 2000-07-04 Theodore Ts'o <tytso@valinux.com>
161 * ext2fs.h: Update to include latest journalling additions to the
164 * dll/jump.funcs: Add new jumptable entries for
165 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
166 ext2fs_badblocks_equal.
168 * tst_badblocks.c: Update test program to test
169 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
171 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
172 writes out bad blocks list to a file.
174 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
175 changes the callback function to take two additional
176 arguments; a private blind pointer supplied by the caller,
177 and pointer to a char * containing a pointer to the
180 * badblocks.c (ext2fs_badblocks_equal): Add new function which
181 returns true if two badblocks list are equal.
183 * Makefile.in: Remove explicit link of -lc in the shared library.
184 (It shouldn't be necessary, and is harmful in some cases).
186 2000-06-10 Theodore Ts'o <tytso@valinux.com>
188 * getsize.c (main): Add debugging code under #ifdef DEBUG
190 2000-05-27 Theodore Ts'o <tytso@valinux.com>
192 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
193 earlier, so that if there's an error reading it, we can
194 more cleanly back out of the operation.
196 2000-05-25 <tytso@snap.thunk.org>
198 * getsize.c (ext2fs_get_device_size): Use open64() instead of
199 open() if it exists. Under linux, manually define the
200 ioctl for BLKGETSIZE if it isn't already defined and it's
203 * unix_io.c (unix_open): Use open64() instead of open() if it
206 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
207 available (and prototypes are defined) use it in
208 preference to llseek.
210 * Makefile: Add hack dependency rule so that parallel makes work
213 2000-05-18 Theodore Ts'o <tytso@valinux.com>
215 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
217 2000-04-03 Theodore Ts'o <tytso@valinux.com>
219 * block.c: Readibility tweak in conditionals involving
222 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
223 how to define __s64 and __u64. Turn off "compression is
224 experimental" warning if the cpp macro
225 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
227 2000-02-11 <tytso@snap.thunk.org>
229 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
230 Conditionally include Compression as a supported type if
231 ENABLE_COMPRESSION (via --enable-compression) is turned on.
233 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
235 2000-02-08 <tytso@snap.thunk.org>
237 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
238 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
239 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
240 Change to return the previous state of the bit that is
241 being marked or unmarked. For speed optimization.
243 2000-02-02 Theodore Ts'o <tytso@valinux.com>
245 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
247 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
248 needed any more; we know it will always be i_generation.
249 Add support for swapping the high bits of the uid and gid.
251 1999-11-19 <tytso@valinux.com>
253 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
254 counts if the link was successful. Patch suggested by
257 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
258 the source directory.
260 1999-11-10 <tytso@valinux.com>
262 * Release of E2fsprogs 1.18
264 1999-11-08 <tytso@valinux.com>
266 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
267 since ext2fs_badblocks_list_free was moved to freefs.c.
269 * tst_badblocks.c: Use the newer badblocks API names. Add
270 duplicate blocks to the test inputs to test dealing with
271 adding blocks which are already in the badblocks list.
273 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
274 of the list, use a shortcut O(1) operations instead of an
275 O(n) operation. (Idea suggested by David Beattie.)
277 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
278 of badblocks_list_free(), to save a procedure call.
280 1999-10-26 <tytso@valinux.com>
282 * Release of E2fsprogs 1.17
284 1999-10-26 <tytso@valinux.com>
286 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
287 seem to handle ~0UL the same way as they used to.
289 1999-10-25 <tytso@valinux.com>
291 * nt_io.c (_OpenNtName): Open the device using
292 FILE_SYNCHRONOUS_IO_NONALERT instead of
293 FILE_SYNCHRONOUS_IO_ALERT
294 (nt_open): At the end of the device open routine, unlock
295 the drive but do not dismount it.
297 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
300 1999-10-22 <tytso@valinux.com>
302 * Release of E2fsprogs 1.16
304 1999-10-22 <tytso@valinux.com>
306 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
308 * link.c (ext2fs_link): This call now uses the low three bits of
309 the flags parameter to pass the directory filetype
310 information; it will set the directory entry FILETYPE
311 information if the filesystem supports it.
313 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
314 option is set, then create the '.' and '..' entries with
315 the filetype set to EXT2_FT_DIR.
317 1999-09-24 <tytso@valinux.com>
319 * nt_io.c: New file which supports I/O under Windows NT.
321 1999-09-07 <tytso@valinux.com>
323 * ext2fs.h: Add new fields for journalling and define new
324 feature bits used by newer filesystems: IMAGIC_INODES,
325 HAS_JOURNAL, RECOVER.
327 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
328 we update the inode block count and size files so that the
329 block count field is updated correctly when we create an
332 1999-07-18 Theodore Ts'o <tytso@valinux.com>
334 * Release of E2fsprogs 1.15
336 1999-06-23 <tytso@valinux.com>
338 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
339 kernels that use i_generation instead of i_version. Patch
340 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
342 1999-06-21 <tytso@valinux.com>
344 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
345 directory entry before calling the callback function.
346 This should prevent some core dumps of insufficiently
347 paranoid callback functions.
349 1999-05-29 <tytso@rsts-11.mit.edu>
351 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
353 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
354 that we don't handle writing yet (we do). Fixed bug where
355 we weren't allocating a big enough buffer for ext2_bmap.
357 1999-05-03 <tytso@rsts-11.mit.edu>
359 * openfs.c (ext2fs_open): Check to make sure that the number of
360 blocks per group is not zero --- if so, it must be a bad
363 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
365 * Release of E2fsprogs 1.14
367 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
369 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
370 the inode number is zero; if it's zero, return
371 EXT2_ET_BAD_INODE_NUM.
373 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
375 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
376 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
379 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
381 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
382 non-Linux case to use EINVAL by default, unless it isn't
383 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
386 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
388 * Release of E2fsprogs 1.13
390 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
392 * Makefile.in: Updated dependencies.
394 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
396 * initialize.c (ext2fs_initialize): Make sure that we allocate
397 enough inodes so that we can make a valid filesystem.
399 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
401 * rw_bitmaps.c: Fixed signed/unsigned warnings.
403 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
404 function declaration.
406 * dblist.c (make_dblist): Add safety check in case the dblist
407 pointer passed in is null (in which case, assign it to
408 fs->dblist). Fixed some signed/unsigned warnings.
410 * bmap.c: Make addr_per_block be of type blk_t to avoid
411 signed/unsigned warnings.
413 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
414 function declaration.
416 * get_pathname.c (get_pathname_proc): Use return value from
417 ext2fs_get_mem, instead of checking if &gp->name is
420 * dir_iterate.c (ext2fs_process_dir_block):
421 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
422 from the function declaration.
424 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
425 return the error directly instead of jumping to the
426 cleanup routine, since we don't need to do any cleanup.
428 * alloc_table.c (ext2fs_allocate_group_table): Make this
429 function take a dgrp_t for its group argument.
431 * ext2fs.h: Make dgrp_t an __u32 type, and make
432 fs->desc_group_count be of type dgrp_t.
434 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
436 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
437 than 10 blocks when we need to expand the size of the
440 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
442 * Release of E2fsprogs 1.12
444 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
446 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
447 appropriate for all of the block group copies, so that
448 it's clear where the beginning of the filesystem is on the
449 disk. (For when the partition table gets scrod.)
451 * ext2fs.h: Change the name of the feature from
452 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
453 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
455 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
457 * inode.c (get_next_blockgroup): Fix bug where if
458 get_next_blockgroup() is called early because of a missing
459 inode table in a block group, the current_inode counter
460 wasn't incremented correctly.
462 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
464 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
465 against a completely trashed bad block inode.
467 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
469 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
470 the stride length hits a bad value, we retry the block
471 allocation starting at the beginning of the block group.
473 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
474 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
475 e2_blkcnt_t to avoid collision with LFS API.
477 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
479 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
480 way that avoids overflows on disk sizes greater than 4GB.
482 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
484 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
485 return type for comparison functions for qsort.
487 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
490 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
492 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
495 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
496 evade a potential problem with glibc's header files trying
497 to spike out linux/types.h.
499 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
500 include the old size of the memory, which is needed for
501 some braindamaged memory allocation systems that don't
504 * badblocks.c (ext2fs_badblocks_list_add):
505 bb_inode.c (clear_bad_block_proc):
506 dblist.c (ext2fs_add_dir_block):
507 icount.c (insert_icount_el):
509 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
510 pass the old size of the memory to be resized to
513 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
515 * Makefile.in: Change to use new installation directory variables
516 convention. Fix uninstall rules to take $(DESTDIR) into
519 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
521 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
522 with 32 bit longs, then we need to manually define __s64
523 and __u64, since the current kernel header files don't
524 define these if __STRICT_ANSI__ is defined. This is a
525 problem if we are compiling with full GCC warnings, since
526 we do need 64 bit support.
528 * Makefile.in (OBJS): Remove bmove.o from files to be built,
529 since we're not using ext2fs_move_blocks() and there
530 is some question as to its usefulness in its current
533 * bmap.c (block_bmap): Remove unused function.
535 * bmove.c (process_block): Fix -Wall warning.
537 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
539 * block.c (ext2fs_block_iterate3): Make the ref_offset field
540 contain the offset into the inode.i_blocks array when
541 ref_block is zero. Since we haven't done a formal
542 release of e2fsprogs since block_iterate2 was first
543 introduced, I removed block_iterate2, and renamed
544 block_iterate3 to be block_iterate2.
546 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
547 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
548 use of block_iterate and block_iterate2 to
549 block_iterate2 with the new prototype for the
550 interator function. (using blkcnt_t forr blockcount)
552 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
554 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
555 s_prealloc_blocks, s_prealloc_dir_blocks). Added
556 conditional defines of new features COMPAT_DIR_PREALLOC,
557 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
558 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
559 the library to declare that we support COMPAT_DIR_PREALLOC,
560 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
562 * fileio.c: Rename function ext2fs_file_llseek to be
563 ext2fs_file_lseek, which is more accurate.
565 * block.c: Add new function ext2fs_block_iterate3 which calls
566 the iterator function with the blockcount argument of
567 type blkcnt_t. This version of the function is
568 allowed to handle large files; the other fucntions are
571 * ext2fs.h: Add new type blkcnt_t
573 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
575 * block.c (ext2fs_block_iterate2): Fix bug where the block count

637 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
639 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
640 so that we don't need to call get_next_blockgroup() the

685 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
687 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
688 paranoid about validating the directory counts from the
689 block group information.
691 * all files: Don't include stdlib.h anymore; include it in
692 ext2_fs.h, since that file requires stdlib.h
694 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
696 * expanddir.c (ext2fs_expand_dir): Check to make sure the block

819 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
820 filesystem has its bitmaps stored as 32-bit words with bit
821 0 as the LSB of each word. Thus a bitmap with only bit 0
822 set would be, as a string of bytes, 00 00 00 01 00 ... To
823 cope with this, we byte-reverse each word of a bitmap if
824 we have a big-endian filesystem, that is, if we are *not*
825 byte-swapping other word-sized numbers.

1007 interface io_channel_bumpcount() to bump the refcount.
1009 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1011 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode

1090 * icount.c (ext2fs_create_icount): Change function so that it also
1091 takes a new argument which contains a "hint" icount
1092 structure. This "hint" icount allows the create function
1093 to set up the sorted list in advance. This reduces
1094 significantly the amount of data moving needed to insert
1095 these inodes into the list later.
1097 * icount.c (ext2fs_icount_validate): New function which validates
1098 that the icount structure's rep invariant.

1101 to subsume put_icount_el(). Put_icount_el() used to
1102 use an O(N) implementation to insert in the middle
1103 of the icount list. It now uses a O(ln N) to search
1104 for where the icount should be inserted, and then uses
1105 a memcpy to move the list down (instead of a for loop).
1107 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1108 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1109 to see if the inode is within bounds; if it isn't, return
1112 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1113 when a bad inode number is passed to test_generic_bitmap
1114 to be EXT2FS_TEST_ERROR instead of the wrong
1115 EXT2FS_UNMARK_ERROR.
1117 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1119 * Release of E2fsprogs version 1.07
1121 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1123 * Makefile.in (ELF_VERSION): Change version to be 2.2
1125 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1127 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1128 ext2fs_fast_test_block_bitmap_range().
1130 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1131 ext2fs_test_block_bitmap_range: New inline functions which
1132 test to see whether a contiguous range of blocks is
1135 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1137 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1138 use ext2fs_badblocks_* instead of badblocks_*
1140 * bb_compat.c: New file which translates between old badblocks_*()
1141 names to ext2fs_badblocks_*()
1143 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1144 link.c (since e2fsck doesn't use ext2fs_unlink()).
1146 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1147 bitmap resizing routine moved from bitmaps.c, since e2fsck
1148 doesn't need to use this function.
1150 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1151 since e2fsck only needs ext2fs_lookup.
1153 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1155 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1156 already set; this is needed so that programs like dump
1157 which use the inode scan functions will deal with
1158 filesystems that have bad blocks in the inode table.
1160 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1162 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1163 Moved to ext2fsP.h, since it doesn't need to be part of
1164 the public interface.
1166 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1168 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1170 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1171 directory block list abstraction. (Code moved from
1174 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1175 to inode.c (since no one else should be peeking inside it!)
1177 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1179 * openfs.c (ext2fs_open): Check the feature set in the ext2
1180 superblock, and refuse to open filesystems if they contain
1181 incompatible features. (Can be overriden with the
1184 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1186 * block.c (ext2fs_block_iterate2): Added new function
1187 ext2fs_block_iterate2 which changes the function
1188 signature of the callback function to include the
1189 referencing block and offset.
1191 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1192 ext2fs_inode_scan_goto_blockgroup which allows an
1193 application to jump to a particular block group while
1194 doing an inode scan.
1196 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1198 * dirblock.c: Include string.h, since we use memcpy().
1200 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1202 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1203 a long not an int; this doesn't matter on i386 machines,
1204 but it does on Alpha's.
1206 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1208 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1209 table pointer is NULL, then return an error indicating
1210 that the inode table is missing.
1211 (get_next_blockgroup, get_next_blocks,
1212 ext2fs_get_next_inode): Don't treat a missing inode table
1213 as permanent error. Return MISSING_INODE_TABLE, but as an
1214 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1216 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1217 ext2fs_write_inode_bitmap): If the inode or block bitmap
1218 block is zero, then don't write out the inode or block
1219 bitmap. The idea here is to avoid stomping on the
1221 (read_bitmaps): If the inode or block bitmap block is
1222 zero, then fill in that portion of the inode or block
1223 bitmap with all zeros.
1225 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1226 blocks in inode table when the inode table size is
1227 non-standard (and can therefore span blocks).
1229 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1231 * alloc.c (ext2fs_new_block): Fix fencepost error in
1232 ext2fs_new_block; make sure we don't try to allocate the
1233 first block beyond the end of the filesystem.
1235 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1237 * inode.c (check_for_inode_bad_blocks): New function called by
1238 get_next_blocks() to avoid reading in bad blocks marked in
1239 fs->badblocks. Inodes located in bad blocks are returned
1240 by ext2fs_get_next_inode() returns the error code
1241 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1243 * alloc_tables.c (ext2fs_allocate_tables): New function which
1244 performs the part of mke2fs's job of allocating the
1247 * test_io.c (test_close): IO manager which is used for testing
1250 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1252 * inode.c (ext2fs_get_next_inode): Separate out the function of
1253 setting up for a new block group to get_next_blockgroup().
1254 Separate out the function of reading in blocks of the
1255 inode table to get_next_blocks().
1257 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1259 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1260 blocks to the badblock list in sorted order. This allows
1261 badblocks_list_test to be coded using a binary search for
1264 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1266 * Release of E2fsprogs version 1.06
1268 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1270 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1271 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1274 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1275 set, then only write out the master superblock.
1277 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1279 * block.c (ext2fs_block_iterate): Fixed bug which caused
1280 block_iterate to fail to handle HURD created filesystems;
1281 it tested the inode translator field before the inode was
1284 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1286 * initialize.c (ext2fs_initialize): Make sure the description for
1287 the inode bitmap is set correctly.
1289 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
1291 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1293 * Release of E2fsprogs version 1.05
1295 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1297 * initialize.c: Override the kernel's idea of default
1298 checkinterval from 0 (never) to 180 days.
1300 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1302 * namei.c (ext2fs_namei_follow): New function which follows
1303 symbolic link (if any) at the target.
1305 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1307 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
1308 for shortcut function fs->read_inode() and fs->write_inode().
1309 Added inode_cache to reduce CPU time spent in doing
1312 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
1315 * namei.c (ext2fs_follow_link): New function.
1316 (ext2fs_namei): Extended to have support for chasing
1317 symbolic links. ext2fs_namei() still returns an inode
1318 which is a symbolic link. Symbolic links are only chased
1319 while resolving the containing directory. To chase
1320 symbolic links of the final result, use
1321 ext2fs_follow_link().
1323 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1325 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1327 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1328 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
1330 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1332 * initialize.c (ext2fs_initialize): On systems where the byte
1333 order is not i386 compatible, set the swap_byte flag.
1335 * inode.c (inocpy_with_swap): Check to see if inode contains a
1336 fast symlink before swapping the inode block fields. This
1337 required adding a new argument to inocpy_with_swap to
1338 determine whether the mode field is in host order or not.
1340 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1342 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1343 the sparc, if EXT2_STD_BITOPS set, use the standard
1344 i386-compatible bitmask operations, instead on the
1345 non-standard native bitmask operators.
1347 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1349 * block.c (ext2fs_block_iterate): Cause block iterator to return
1350 the HURD translator block (along with everything else).
1351 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1352 iterator, then don't return any meta data blocks
1353 (including the HURD translator).
1355 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1357 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1359 * uuid.c: New file, containing UUID utility functions.
1361 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1363 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1365 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1367 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1369 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1371 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1372 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1373 that's a basic value that must be correct for the rest of
1374 the library to work.
1376 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1379 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1381 * Release of E2fsprogs version 1.04

1385 * Release of E2fsprogs version 1.03
1387 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
1389 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
1390 Change the m68k bit numbering for bitmasks to match with
1391 the bit numbering used by all other ext2 implementations.
1393 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1395 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
1396 ext2fs_open_inode_scan): Support dynamically-sized inodes.
1398 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>
1400 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Support
1401 dynamically-sized inodes.
1403 * openfs.c (ext2fs_open): Allow dynamic revision filesystem to be

1409 the passed in size is *really* too small.
1411 * alloc.c (ext2fs_new_inode):
1412 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
1415 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
1417 * getsize.c (ext2fs_get_device_size): Open the device read-only
1418 when trying to determine its size.
1420 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1422 * Release of E2fsprogs version 1.02
1424 Sat Dec 9 09:57:50 1995 <tytso@rsts-11.mit.edu>
1426 * rw_bitops.c (ext2fs_write_block_bitmap):
1427 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1428 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1429 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1430 to avoid conflicts with with kernel include files. Also
1431 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1434 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1436 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1438 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1439 s_def_resuid and s_def_resgid for backwards compatibility.
1441 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

1445 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
1447 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
1450 * closefs.c: #include <string.h> to pick up memset() declaration
1452 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1454 * Makefile.in: Added support for BSD shared libraries.
1456 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1459 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1461 * unix_io.c (unix_open): Add a double check; if the passed in name
1462 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1464 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1466 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
1468 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
1471 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
1473 * getsize.c (ext2fs_get_device_size): Add support for reading the
1474 partition size from a BSD disk label.
1476 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1478 * getsize.c (ext2fs_get_device_size): New function that determins
1479 the size of a device. Used by mke2fs and e2fsck.
1481 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1483 * Makefile.in (install): Install static libraries in $(ulibdir)
1484 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
1486 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
1488 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1489 Move these functions to freefs.c.
1491 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1492 descriptors shadow memory to keep purify quiet. (This
1493 also has the nice benefit that the unused portion of the
1494 shadow descriptors are zeroed out.)
1496 * dirblock.c (ext2fs_write_dir_block): We need to use
1497 dirent->rec_len *before* it's byteswapped to find the
1498 location of the next directory structure!
1500 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1501 cause ext2fs_new_inode to loop infinitely if we're trying
1502 to allocate an inode in group #0 and there are no free
1503 inodes at all in the system.
1505 * closefs.c: #include <errno.h> if it exists.
1507 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1509 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1515 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1516 installation directories correctly.
1518 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>

1521 * mkdir.c (ext2fs_mkdir):
1522 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1523 to read/write the directory block.
1525 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1526 file containing functions for reading and writing
1527 directory blocks (byte swapping if necesssary)
1529 * block.c (block_iterate_ind, block_iterate_dind,
1530 block_iterate_tind): Byte swap the block addresses if
1531 EXT2_SWAP_BYTES is set (and swap them back before writing
1534 * inode.c (inocpy_with_swap): New function.
1535 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1536 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1538 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1539 the superblock and group descriptors before writing it out.
1541 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1542 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1543 and group descriptors.
1545 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1546 to desp ext2 filesystem structures.
1548 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1549 supplied by Pete A. Zaitcev so that the C language
1550 versions of these functions are more portable. They will
1551 now work on both little and big endian systems, and the
1552 assumption that 32-bit integers are used is gone.
1554 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1555 doing byte swapping.
1557 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1558 byte swapping should take place.
1560 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1562 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
1563 ext2fs_compare_inode_bitmap_end): Added new file
1564 containing routines to compare bitmaps.
1566 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1567 Added new error codes.
1569 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1571 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1572 if the magic number is correct, it will be allocated.
1574 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1576 * block.c (block_iterate_ind, block_iterate_dind,
1577 block_iterate_tind): Don't recompute block_nr each loop;
1578 just increment it! Factor check of BLOCK_FLAG_APPEND out
1579 of the loop. Factor mask of BLOCK_CHANGED into changed
1580 variable out of the loop. (block_iterate_ind, in
1581 particular, gets called a lot, so every little
1582 optimization helps.)
1584 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1586 * block.c (block_iterate_ind, block_iterate_dind,
1587 block_iterate_tind): Precompute limit of loop to speed up
1588 block_iterate_ind and company.
1590 * bitops.h (ext2fs_fast_mark_block_bitmap,
1591 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1592 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1593 ext2fs_fast_test_inode_bitmap): Add fast version of these
1594 functions, which don't do range checking.

1597 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1598 ext2fs_get_inode_bitmap_end): Add new accessor functions
1599 which return the start and end points of the bitmaps.
1601 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1603 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1604 instead of llseek. The errno if the offset is too large
1605 and lseek is not supported should be EINVAL, not -EINVAL.
1607 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1609 * Makefile.in: Added support for ELF shared libraries.
1610 Fixed typos in the compilation rules.
1611 (distclean): Added Makefile.
1613 * llseek.c (llseek): New function, if llseek() does not exist in the
1615 (ext2_llseek): Changed to call llseek().
1617 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1619 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1621 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1623 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1625 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1626 the S_*, which are normally defined in <sys/stat.h>. This
1627 allows us to compile e2fsprogs on a non-Linux system,
1628 which may have a different value for S_IFDIR.
1630 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1632 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1633 this is a user-mode application!
1635 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1637 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1638 __linux__ so that non-linux systems won't see it.
1640 * alloc.c: Include <errno.h> if possible.
1641 * badblocks.c: Ditto.
1642 * bb_inode.c: Ditto.
1645 * expanddir.c: Ditto.
1646 * get_pathname.c: Ditto.
1647 * initialize.c: Ditto.
1654 * rw_bitmaps.c: Ditto.
1657 * Makefile.in: Rewritten to conform to GNU coding standards and
1658 support separate compilation directories.
1660 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1662 * initialize.c (ext2fs_initialize): Don't allow more than one
1663 bitmaps's worth of inodes in a group.
1665 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1667 * llseek.c (ext2_llseek): Added error checking to the llseek()
1668 compat code to protect against overflow. This only
1669 applies to 1.0 and early 1.1 kernels, which don't support
1670 the llseek() system call.
1672 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1674 * unix_io.c (unix_open): Initialize the read_error and write_error
1675 io_channel pointers to be null.
1677 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1678 found, clear it but don't try to update the filesystem
1679 accounting information, since that's hopeless anyway.
1681 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1682 bloblock_iterate_tind): Check to see if the indirect blocks are
1683 valid before trying to read them.

1688 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1689 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1690 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1691 illegal block or inode number is passed in, return instead
1692 of trying to test, set, or clear the bit.
1694 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1696 * Makefile: Added a dummy install target in case shared libraries
1699 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1701 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

1707 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1708 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1709 ext2fs_free_block_bitmap): Add magic number checking for
1710 the inode and block bitmaps.
1712 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1713 magic number for a block bitmap instead of an inode bitmap.

1716 magic number checking for the inode_scan structure.
1718 * badblocks.c (badblocks_list_free, badblocks_list_add,
1719 badblocks_list_test, badblocks_list_iterate_begin,
1720 badblocks_list_iterate, badblocks_list_iterate_end): Add
1721 magic number checking for the badblocks_list and
1722 badblocks_iterate structures.
1724 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1725 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,

1727 both for io_channel structure and unix_private_data
1730 * openfs.c (ext2fs_open): Add check for io_manager structure's
1733 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1734 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1735 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1736 * read_bb.c (ext2fs_read_bb_inode):
1737 * read_bb_file.c (ext2fs_read_bb_FILE):

1748 ext2fs_allocate_block_bitmap):
1749 * bb_inode.c (ext2fs_update_bb_inode):
1750 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):

1758 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1759 openfs.c into its own file.
1761 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1762 structure magic numbers.
1764 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1765 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1766 someone uses the -b option to specify the use of the backup
1767 superblock --- this usually means that the main superblock is
1771 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1772 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1773 revision level to the superblock.
1775 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1782 * initialize.c: Completely revamped the inode and block bitmap
1783 structures, so that they can be better chance of being extensible
1784 in a shared library. They are now their own type, instead of
1785 being a char *. Also, the function signatures of
1786 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1787 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1788 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1789 changed to eliminate the ext2_filsys argument, since it is no
1792 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1794 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1795 system call if available.
1797 * llseek.c: new file. This is the stub calling the llseek system
1798 call which allows supports for 2GB+ file systems.
1800 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1801 the creator operating system.
1803 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1805 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1806 the group descriptor statistics in addition to everything else.
1807 This relieves mke2fs of the responsibility of doing it.
1809 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1810 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1811 not the generic C function equivalents should be included or not.
1813 * openfs.c (ext2fs_open): If a superblock is specified, then use
1814 the backup group descriptors that go along with this superblock,
1815 instead of using the primary group descriptors. This allows
1816 e2fsck to recover filesystems where the primary group descriptors
