1 2006-03-29 Theodore Ts'o <tytso@mit.edu>
3 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit): Fix the constraints
4 so that GCC knows that the ext2fs_set/clear_bit reads and
7 2006-03-25 Theodore Ts'o <tytso@mit.edu>
9 * Makefile.in: Check the bitfield operations much more carefully,
10 and arrange to have tst_bitops run from "make check"
12 * tst_bitops.c: Enahce tst_bitops program so that it is much more
13 thorough in testing bit optations.
15 * bitops.h: Add new functions ext2fs_fast_set_bit() and
16 ext2fs_fast_clear_bit() and make the x86 functions 32-bit
17 clear. Change the fast inode and block mark/unmark
18 functions to use ext2fs_fast_set/get_bit()
20 2006-03-18 Theodore Ts'o <tytso@mit.edu>
22 * ext2fs.h (EXT2_FLAG_EXCLUSIVE): Define new flag which requests
23 that the io_channel be opened in exclusive mode.
25 * openfs.c (ext2fs_open2), initialize.c (ext2fs_initialize): If
26 EXT2_FLAG_EXCLUSIVE is passed to ext2fs_open or
27 ext2fs_initialize, then pass IO_FLAG_EXCLUSIVE to the
28 io_channel open routine.
30 * ext2_io.h (IO_FLAG_EXCLUSIVE), unix_io.c (unix_open): Add new
31 io_channel open flag, IO_FLAG_EXCLUSIVE, which requests
32 that the device be opened in exclusive (O_EXCL) mode.
34 * ext2fs.h: Fix documentation so that BLOCK_FLAG_TRAVERSE is
35 BLOCK_FLAG_DEPTH_TRAVERSE. (Addresses Debian Bug #351268)
37 2006-03-17 Theodore Ts'o <tytso@mit.edu>
39 * initialize.c (calc_reserved_gdt_blocks): Fix a signed vs
40 unsigned problem which caused mke2fs -O resize_inode to
41 bomb out on large filesystems. (Addresses Debian Bug
44 * ext2_fs.h (EXT2_IOC_GETVERSION_NEW, EXT2_IOC_SETVERSION_NEW,
45 EXT2_IOC_GROUP_EXTEND, EXT2_IOC_GROUP_ADD): Add ioctl
48 2005-12-10 Theodore Ts'o <tytso@mit.edu>
50 * Makefile.in: Add a dependency to make sure that the
51 subdirectories are created before creating all of the
54 2005-12-10 Theodore Ts'o <tytso@mit.edu>
56 * res_gdt.c (ext2fs_create_resize_inode): Fix type-punning warning.
58 * read_bb_file.c (ext2fs_read_bb_FILE): Use a data structure
59 instead of stuffing a function pointer dirctly into a void
60 pointer, since that isn't portable.
62 * mkjournal.c (ext2fs_add_journal_inode): Fix possiblely
63 uninitialized use of variable warning.
65 * initialize.c (calc_reserved_gdt_blocks): Fix signed vs. unsigned
68 * ext2fs.h: Make the type of the 'now' field to be time_t to avoid
71 * bitops.h (ext2fs_find_first_bit_set): Fix signed vs unsigned
74 * tst_badblocks.c (file_test_invalid): Add test which confirms
75 proper detection of invalid block numbers in
76 ext2fs_read_bb_FILE().
78 2005-11-20 Theodore Ts'o <tytso@mit.edu>
80 * bitops.h: We no longer have the sparc assembly code in the
81 header file any more, so we shouldn't set
82 _EXT2_HAVE_AS_BITOPS_. This would break compiles on the
83 sparc architectures when using gcc.
85 2005-11-13 Theodore Ts'o <tytso@mit.edu>
87 * ext2fs.h: Add #include <string.h> since the inline functions use
88 memcpy(). (Addresses Sourceforge Bug #1251062)
90 2005-11-09 Theodore Ts'o <tytso@mit.edu>
92 * Fix a bug when writing an external journal device on an big
93 endian machine (such as a S/390), where when the number of
94 block groups is zero, we never end up writing out the
95 primary superblock at all.
97 2005-09-24 Theodore Ts'o <tytso@mit.edu>
99 * ext2fs.h, bb_inode.c, closefs.c, initialize.c, mkdir.c,
100 mkjournal.c, res_gdt.c: If fs->now is non-zero, use that
101 as the time instead of the system time when setting
102 various filesystem fields (last modified time, last write
105 2005-08-28 Matthias Andree <matthias.andree@gmx.de>
107 * Fix compiler warnings about missing memcpy prototypes.
109 2005-07-25 Theodore Ts'o <tytso@mit.edu>
111 * test_io.c (safe_getenv): Pass in zero to the unusued arguments
112 of prctl(PR_GET_DUMPABLE) to avoid false positives from
115 2005-07-19 Theodore Ts'o <tytso@mit.edu>
117 * mkjournal.c (ext2fs_add_journal_inode): Check for the case where
118 the filesystem is apparently not mounted, but the device
119 is still busy. This can happen when the luser doesn't
120 bother to mount /proc and has a bogus /etc/mtab, but still
121 wants to mount the filesystem before using tune2fs(?!?).
122 Add a safety check to save him from his own stupidity, at
123 least on 2.6 kernels. (Addresses Debian Bug #319002)
125 2005-07-09 Andreas Dilger <adilger@clusterfs.com>
127 * getsize.c (ext2fs_get_device_size): Use fstat/fstat64 to get
128 size of regular files. Fix file descriptor leaks in error
131 2006-06-30 Theodore Ts'o <tytso@mit.edu>
133 * Release of E2fsprogs 1.38
135 2005-06-30 Theodore Ts'o <tytso@mit.edu>
137 * bitops.h, bitops.c (ext2fs_set_bit, ext2fs_clear_bit,
138 ext2fs_test_bit): Change these function prototypes to be
139 unsigned int's. Negative bit numbers were never allowed
140 (and never made any sense), so this should be a safe
141 change. This is needed to allow safe use of block numbers
142 greater than or equal to 2**31.
144 2005-06-27 Stephen Tweedie <sct@redhat.com>
146 * ext2fs.h (ext2fs_resize_mem): Fix C99 strict type aliasing
147 problems. Addresses Red Hat Bugzilla #161183.
149 2005-06-19 Theodore Ts'o <tytso@mit.edu>
151 * getsectsize.c (BLKSSZGET): Clean up test for when to manually
152 define the BLKSSZGET ioctl.
154 2005-05-29 Theodore Ts'o <tytso@mit.edu>
156 * ismounted.c (ext2fs_check_mount_point): Add test to see if the
157 device appears to be busy; this only works on Linux 2.6+
158 systems, but provides some additional bullet-proofing in
161 2005-05-08 Theodore Ts'o <tytso@mit.edu>
163 * test_io.c (safe_getenv): Fix bug so it would fetch the right
164 environment variable.
166 2005-04-09 Theodore Ts'o <tytso@mit.edu>
168 * inode.c (ext2fs_write_new_inode),
169 ind_block.c (ext2fs_read_ind_block): Add missing return
170 value in error return case. (Otherwise we return garbage
171 instead of the error code.)
173 2005-03-31 Theodore Ts'o <tytso@mit.edu>
175 * test_io.c (test_open): If called by a setuid/setgid or an
176 otherwise privileged program, be paranoid and ignore the
177 TEST_IO_* environment variables.
179 2005-03-21 Theodore Ts'o <tytso@mit.edu>
181 * Release of E2fsprogs 1.37
183 2005-03-21 Theodore Ts'o <tytso@mit.edu>
185 * ext2_ext_attr.h (EXT2_XATTR_LEN, EXT2_XATTR_SIZE): Add new
186 convenience cpp macros.
188 2005-03-20 Theodore Ts'o <tytso@mit.edu>
190 * mkdir.c (ext2fs_mkdir): Call ext2fs_write_new_inode() instead of
191 ext2fs_write_inode().
193 * inode.c (ext2fs_write_new_inode): New function which should be
194 used when the caller is writing an inode for the first
195 time. It makes sure that the extra portion of the large
196 inode is initialized properly.
198 2005-03-18 Theodore Ts'o <tytso@mit.edu>
200 * Makefile.in: Fix clean target to remove tst_getsectsize.
202 * getsize.c (ext2fs_get_device_size): Check to see if the number
203 of blocks is greater than 2**32 when we are doing a binary
204 search to determine the device size. Thanks to Stephen
205 Tweedie for the patch.
207 2006-02-05 Theodore Ts'o <tytso@mit.edu>
209 * Release of E2fsprogs 1.36
211 2005-02-05 Theodore Ts'o <tytso@mit.edu>
213 * Makefile.in: Remove ext2fs.pc on a "make distclean"
215 2005-02-04 Theodore Ts'o <tytso@mit.edu>
217 * Makefile.in (clean): Remove tst_getsize when doing a make clean
219 2005-02-03 Theodore Ts'o <tytso@mit.edu>
221 * bitops.c: Make the generic functions more efficient.
223 * bitops.h: Drop SPARC assembly code. It's less efficient than GCC
224 3.4 compiled code and also triggers nasty compiler
225 warnings on sparc64. Thanks to Matthias Andree for his
226 analysis and suggestion.
228 2005-01-27 Theodore Ts'o <tytso@mit.edu>
230 * res_gdt.c (ext2fs_create_resize_inode): Create the resize inode
231 even if s_reserved_gdt_blocks is zero.
233 2005-01-26 Theodore Ts'o <tytso@mit.edu>
235 * ext2fs.pc.in: Add pkg-config files.
237 2005-01-25 Theodore Ts'o <tytso@mit.edu>
239 * ext2fs.h: Add definition of struct ext2_inode_large
241 * ext2_fs.h: Add new function prototypes
243 * ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr): The
244 ext2fs_swap_ext_attr() has been moved to swapfs.c, and
245 given a new argument, has_header.
247 * swapfs.c (ext2fs_swap_ext_attr): Moved from ext_attr.c, and
248 takes an argument which controls whether or not there is
249 an EA header which needs to be byteswaped.
250 (ext2fs_swap_inode_full): New function which byte-swaps
253 * inode.c (ext2fs_get_next_inode_full, ext2fs_read_inode_full,
254 ext2fs_write_inode_full): New functions, originally from
255 Alex Tomas, but which needed to be substantially fixed so
256 that the tests wouldn't cause major stack overwrite bugs
257 in byte-swapping is enabled.
259 2005-01-18 Theodore Ts'o <tytso@mit.edu>
261 * Makefile.in: Fix the kernel compile-time echo commands to be
262 consistent and portable
264 2005-01-07 Theodore Ts'o <tytso@mit.edu>
266 * unlink.c (ext2fs_unlink): If both the name and the inode number
267 are unspecified, then return an error, so that we don't do
268 something surprising such as unconditionally deleting the
269 first directory entry.
270 (unlink_proc): Delete directory entries by coalescing it
271 with the previous entry, to avoid directory fragmentation.
273 2005-01-06 Theodore Ts'o <tytso@mit.edu>
275 * version.c (ext2fs_parse_version_string): Change parsing
276 algorithm so that version strings such as 1.36-rc1 returns
277 a non-surprising result (i.e., 136, and not 1361).
279 2005-01-05 Theodore Ts'o <tytso@mit.edu>
281 * block.c (block_iterate_ind, block_iterate_dind,
282 block_iterate_tind): Move the code which byte swaps and
283 read/writes indirect blocks to ext2fs_{read,write}_ind_block.
284 This saves 400 bytes, and we need them for the
285 resize_inode handling.
287 * ind_block.c (ext2fs_read_ind_block, ext2fs_write_ind_block): New
290 * res_gdt.c (ext2fs_create_resize_inode): Use
291 ext2fs_{read,write}_ind_block so that byte swapping is
292 handled on big-endian systems.
294 * dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handle
295 has its own copy of the orig_super data structure. (This
296 is a better way of fixing a double-free problem in
297 resize2fs which Fedora attempted to fix in
298 e2fsprogs-1.35-double_free.patch. Addresses Red Hat
301 2004-12-23 Theodore Ts'o <tytso@mit.edu>
303 * inode.c (ext2fs_flush_icache): When flushing the icache, clear
304 the last-read block information as well.
306 * ext2fs.h (BMAP_SET), bmap.c (ext2fs_bmap): Add support for new
307 flag, BMAP_SET, which allows the caller to set a
308 particular logical->physical block mapping.
310 * ext2_err.et.in (EXT2_ET_SET_BMAP_NO_IND): New error code
312 * initialize.c (calc_reserved_gdt_blocks): #ifdef out all
313 debugging printf statements.
315 * res_gdt.c (ext2fs_create_resize_inode): Return
316 EXT2_ET_RESIZE_INODE_CORRUPT if the resize inode is not
317 what we expect. #ifdef out all debugging printf
320 * ext2_err.et.in (EXT2_ET_RESIZE_INODE_CORRUPT): Add new error code.
322 2004-12-22 Theodore Ts'o <tytso@mit.edu>
324 * swapfs.c (ext2fs_swap_super): Byteswap the reserved_gdt_blocks
327 2004-12-15 Theodore Ts'o <tytso@mit.edu>
329 * sparse.c (ext2fs_list_backups, ext2fs_bg_has_super),
330 res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
331 ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
332 ext2fs_bg_has_super() back to closefs.c. There's no
333 reason for the new file, since list_backups() isn't being
334 used by any other functions, and can be made static, and
335 all users of the ext2fs filesystem will have to call
336 ext2fs_close() anyway.
338 2004-12-15 Theodore Ts'o <tytso@mit.edu>
340 * Applied resize inode patch from Andreas Dilger
342 * res_gdt.c (ext2fs_create_resize_inode): New function that
343 creates the resize inode.
345 * initialize.c (ext2fs_initialize): Reserve space for the resize
348 * ext2fs.h (EXT2_LIB_FEATURE_COMPAT_SUPP): Add
349 EXT2_FEATURE_COMPAT_RESIZE_INODE to the list of supported
351 Add function prototypes for res_gdt.c and sparse.c.
353 * closefs.c (ext2fs_super_and_bgd_loc): Take the reserved blocks
354 into account when calculating the number of overhead
357 * closefs.c (ext2fs_bg_has_super, test_root), sparse.c: Move these
358 functions to the new file sparse.c
360 * alloc_sb.c (ext2fs_reserve_super_and_bgd): Reserve the blocks
361 saved in the resize inode as being in use.
363 * ext2_err.et.in (EXT2_ET_RES_GDT_BLOCKS): Add new error code.
365 * Makefile.in (srcdir): Add res_gdt.c and sparse.c to the ext2fs

378 * unix_io.c (unix_set_option): Add support for the offset option.
380 * test_io.c (test_set_option): Add support for the set_option method.
382 * ext2_io.h: Add new io_channel method, set_option(), and change
383 io_channel_write_byte() from a macro to a library function.
385 * ext2fs.h, openfs.c(ext2fs_open2): New version of ext2fs_open
386 which adds a new parameter, io_options.
387 (ext2fs_open): If there is a question mark in the
388 filename, and no io_options are specified, assumed that
389 the text following the question mark are io_options.
391 * io_manager.c, Makefile.in: New source file which contains
392 high-level functions for the io_channel layer.
394 * freefs.c (ext2fs_free): Make sure we don't free the io_channel
397 * Makefile.in: Use Linux-kernel-style makefile output to make it
398 easier to see errors/warnings.
400 2004-11-29 Theodore Ts'o <tytso@mit.edu>
402 * ext2_fs.h (EXT2_EXTENTS_FL, EXT3_FEATURE_INCOMPAT_EXTENTS,
403 EXT2_MAX_BLOCK_LOG_SIZE): Add definition for extent
404 feature and inode flag. Change maximum allowable block
407 2004-10-08 Theodore Ts'o <tytso@mit.edu>
409 * getsize.c (ext2fs_get_device_size): Add support for Windows
410 9x/NT under Cygwin. Thanks to Sam Robb
411 (samrobb@users.sourceforge.net) for pointing this and the
412 suggested code patch.
414 2004-09-17 Theodore Ts'o <tytso@mit.edu>
416 * getsize.c: Clean up header #include's.
418 * llseek.c (ext2fs_llseek): On non-linux systems, use lseek64() if
419 it is present. (Addresses Debian bug #269044)
421 2004-07-28 Theodore Ts'o <tytso@mit.edu>
423 * rw_bitmaps.c (read_bitmaps), block.c (block_iterate_ind,
424 block_iterate_dind, block_iterate_tind), inode.c
425 (ext2fs_read_inode): If EXT2_FLAG_IMAGE_FILE is set, so
426 read the metadata from fs->image_io instead of fs->io.
428 * initialize.c (ext2fs_initialize), openfs.c (ext2fs_open):
429 Initialize fs->image_io to be the same as fs->io.
431 * ext2_err.et.in (EXT2_ET_NOT_IMAGE_FILE): Add new error code.
433 * openfs.c (ext2fs_get_data_io, ext2fs_set_data_io,
434 ext2fs_rewrite_to_io): New functions that allow
435 applications to manipulate fs->image_io and fs->io safely.
437 * freefs.c (ext2fs_free): If fs->image_io is different fs->io,
438 then call io_channel_close on fs->image_io.
440 * ext2fs.h: Add image_io element to the ext2_filsys data
441 structure. Add ext2fs_get_data_io() ext2fs_set_data_io(),
442 and ext2fs_rewrite_to_io() prototypes.
444 2004-05-26 Theodore Ts'o <tytso@mit.edu>
446 * closefs.c (ext2fs_flush): Make sure the master superblock is
447 written last, and only after other I/O has been flushed to
448 disk. Thanks to Junfeng Yang from the Stanford
449 Metacompilation group for pointing a potential ordering
450 constraint problem if we don't write things out in the
453 * test_io.c: Implement the ability to abort after n reads or
454 writes to a particular block. The block is specified by
455 TEST_IO_BLOCK environment variable, and the read/write
456 count by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT
457 environment variables. The block data is now only dumped
458 if the 0x10 bit is set in TEST_IO_FLAGS.
460 2004-04-03 Theodore Ts'o <tytso@mit.edu>
462 * ext2_types.h.in: Remove check for _UUID_TYPES since uuid_types.h
465 2004-03-08 Theodore Ts'o <tytso@mit.edu>
467 * getsize.c (ext2fs_get_device_size): Only use the BLKGETSIZE64
468 ioctl on Linux 2.6 since it is unreliable in Linux 2.4.
469 (Addresses Debian Bug #236528). Fix typo in the ioctl
472 2004-03-02 Theodore Ts'o <tytso@mit.edu>
474 * getsize.c (ext2fs_get_device_size): Update getsize functions to
475 use Apple Darwin and Linux 64-bit ioctl's
477 2004-02-29 Brian Bergstrand <brian@bergstrand.org>
479 * Makefile.in: Use $(BSDLIB_PIC_FLAG) to determine whether to use
482 2004-02-28 Theodore Ts'o <tytso@mit.edu>
484 * Release of E2fsprogs 1.35
486 2004-02-21 Theodore Ts'o <tytso@mit.edu>

489 Hat Bugzilla #112448; thanks Thomas Woerner from Red Hat.)
491 2004-02-14 Theodore Ts'o <tytso@mit.edu>
493 * namei.c (follow_link): Correctly deal with symlinks that have
494 extended attribute information. (Addresses Debian Bug
497 2004-01-30 Theodore Ts'o <tytso@mit.edu>
499 * ext2_fs.h: Reserve an extra 4 bytes for the journal backup,
500 which we're using due to a typo in the e2fsck code. (Oops)
502 * swapfs.c (ext2fs_swap_inode): Fix byte swap bug which causes SE
503 Linux created symlinks with mandatory attributes to fail
504 to be properly handled on big endian systems. (Addresses
506 (ext2fs_swap_super): Byte swap some new fields in the
507 superblock, including the journal backup fields.

514 lookup.c, openfs.c, read_bb.c, read_bb_file.c,
515 rw_bitmaps.c, unix_io.c, unlink.c, write_bb_file.c: Fix
516 gcc -Wall complaints. Mainly marking variables as being
517 unsued, and catching signed vs. unsigned comparisons.
519 2003-09-03 Theodore Ts'o <tytso@mit.edu>
521 * closefs.c (ext2fs_super_and_bgd_loc): New function which
522 centralizes the calculation of the superblock and block

525 out where to write the superblock and block group
528 * alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
529 reserves space in the block bitmap using
530 ext2fs_super_and_bgd_loc.
532 * initialize.c (ext2fs_initialize): Use
533 ext2fs_reserve_super_and_bgd to initialize the block bitmap.
535 2003-08-20 Theodore Ts'o <tytso@mit.edu>
537 * inode_io.c (ext2fs_inode_io_intern2), ext2fs.h: Add new function
538 allows the caller to pass in the inode data structure.
540 * fileio.c (ext2fs_file_open2), ext2fs.h: Add new function which

560 'void *' instead of a 'void **' in order to avoid pointer
561 aliasing problems with GCC 3.x.
563 2003-07-25 Theodore Ts'o <tytso@mit.edu>
565 * Release of E2fsprogs 1.34
567 2003-07-06 Theodore Ts'o <tytso@mit.edu>
569 * kernel-jbd.h, flushb.c: Fix gcc -Wall nitpicks (indented cpp
572 * ext2_types.h.in, initialize.c: Fix gcc -Wall nitpicks
575 * ismounted.c: Fix gcc -Wall nitpicks (Don't use exit as a goto label)
577 * llseek.c: Fix gcc -Wall nitpicks (don't use #elsif)
579 * lookup.c, read_bb.c: Fix gcc -Wall nitpicks (indent
580 non-traditional #pragma)
582 * test_io.c: Fix gcc -Wall nitpicks (const/unsigned type issues)
584 2003-06-24 <tytso@snap.thunk.org>
586 * badblocks.c, ext2fs.h (ext2fs_u32_list_find,
587 ext2fs_u32_list_test, ext2fs_u32_list_del,
588 ext2fs_badblocks_list_del): Add functions to delete a
589 block from the badblocks list.
590 * tst_badblocks.c: Add test cases for ext2fs_badblocks_list_del().
592 2003-05-21 Theodore Ts'o <tytso@mit.edu>
594 * getsectsize.c (ext2fs_get_device_sectsize): New function which
595 returns the hardware sector size (if it is available).
597 2003-05-13 Theodore Ts'o <tytso@mit.edu>
599 * unix_io.c: Add #ifdef NO_IO_CACHE which disables all userspace
600 caching by the unix_io layer. Not enabled, only for
603 2003-05-05 Theodore Ts'o <tytso@mit.edu>
605 * test_io.c: Pay attention to the environment variables
606 TEST_IO_LOGFILE, TEST_IO_FLAGS, and TEST_IO_BLOCK to
607 determine whether or not we should log io activity, and to
610 2003-05-03 Theodore Ts'o <tytso@mit.edu>
612 * tst_badblocks.c (file_test): Use tmpfile() instead of mktemp().
614 2003-04-29 Theodore Ts'o <tytso@mit.edu>
616 * getsize.c (ext2fs_get_device_size): Allow windows code to get
617 the resize for filesystems that are in regular files.
619 2003-04-21 Theodore Ts'o <tytso@mit.edu>
621 * Release of E2fsprogs 1.33
623 2003-04-21 Theodore Ts'o <tytso@mit.edu>
625 * Makefile.in: Use DYLD_LIBRAY_PATH so that "make check" works on
626 Darwin systems when building with shared libraries.
628 2003-04-18 Theodore Ts'o <tytso@mit.edu>
630 * unix_io.c: Use __CYGWIN__ instead of CYGWIN.
632 2003-04-17 Theodore Ts'o <tytso@mit.edu>
634 * getsize.c: Add Cygwin/Windows version of ext2fs_get_device_size()
636 2003-04-12 Theodore Ts'o <tytso@mit.edu>
638 * unix_io.c (raw_read_blk): Add Cygwin support (the Windows block
639 device only accepts sector aligned read requests.
641 * ismounted.c (check_mntent_file): Deal with OS's that don't
644 * imager.c: If the OS doesn't define ssize_t, typedef it to int.
646 2003-04-11 Theodore Ts'o <tytso@mit.edu>
648 * ext2_fs.h (EXT2_FEATURE_RO_COMPAT_BTREE_DIR): Comment out unused
651 2003-03-30 Theodore Ts'o <tytso@mit.edu>
653 * Makefile.in: Use the compile_et --build-tree option.
655 2003-03-14 Theodore Ts'o <tytso@mit.edu>
657 * getsize.c: Add support for Apple Darwin's ioctl to get the hard
660 * badblocks.c (ext2fs_u32_list_count), ext2fs.h: Add new function
661 which returns the number of entries in the list.
663 2003-03-10 Theodore Ts'o <tytso@mit.edu>
665 * fileio.c (ext2fs_file_lseek): Fix bug added when adding 64-bit
666 support; avoid null dereference when ret_pos is NULL.
668 2003-03-06 Theodore Tso <tytso@mit.edu>
670 * ext2_types.h.in: Don't redefine types if other e2fsprogs
671 *_types.h files have been included already.
673 * kernel-jbd.h: Use C99 variadic cpp macros if not using GCC.
674 (Older GCC's don't support the C99 variadic macros.)
676 * flushb.c (ext2fs_sync_device),
677 ismounted.c (ext2fs_check_mount_point): Avoid GCC extension:
678 #warning not supported by Solaris suncc
680 * ext2_ext_attr.h: Avoid GCC extension: 0 length arrays in
681 structure definition. Not needed for now in
684 2003-01-25 Theodore Ts'o <tytso@mit.edu>
686 * dirhash.c: Fix gcc -Wall nits.
688 2003-01-22 Theodore Ts'o <tytso@mit.edu>
690 * unix_io.c (unix_write_blk): Fix up GCC -Wall nits.
692 2003-01-21 Theodore Ts'o <tytso@mit.edu>
694 * fileio.c (ext2fs_file_read, ext2_file_lseek,
695 ext2_file_get_size): Add 64-bit support.
697 * ext2fs.h (EXT2_I_SIZE): Add macro which caluates a 64bit size
698 from i_size and i_size_high.
700 2003-01-19 Theodore Ts'o <tytso@mit.edu>
702 * initialize.c (ext2fs_initialize): If the user specifies a really
703 large number of inodes, then reduce the number of blocks
704 per group until we find a workable set of filesystem
707 * ext2_err.et.in (EXT2_ET_TOO_MANY_INODES): Add new error code.
709 2002-11-09 Theodore Ts'o <tytso@mit.edu>
711 * Release of E2fsprogs 1.32
713 2002-11-09 Theodore Ts'o <tytso@mit.edu>
715 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
716 unix_write_blk): Optimize routines so that we don't end up
717 searching the cache twice when a block isn't in the
718 cache. If reads are larger than READ_DIRECT_SIZE, don't
719 let them go through the cache.
721 * unix_io.c (find_cached_block): Fixed bug which caused some clean
722 blocks to be erroneously marked as dirty, so they would
723 get written back to the disk before they are evicted from
724 the cache. Harmless, but it slows down e2fsck
727 2002-11-08 Theodore Ts'o <tytso@mit.edu>
729 * Release of E2fsprogs 1.31
731 2002-11-08 <tytso@snap.thunk.org>
733 * Makefile.in (check): Skip trying to compile test_byteswap
734 if --disable-byteswaap had been given to configure.
736 2002-11-07 <tytso@snap.thunk.org>
738 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
739 support when the MASTER_SB_ONLY flag is set. Some of
740 the descriptor blocks that should have been written out
741 were getting skipped.
743 2002-10-31 Theodore Ts'o <tytso@mit.edu>
745 * Release of E2fsprogs 1.30
747 2002-10-31 Theodore Ts'o <tytso@mit.edu>
749 * ext2_fs.h: Add support for a new inode flag, which is to be used
750 for indicating the top of directory hierarchies for the
751 Orlov block allocator.
753 * ismounted.c (check_mntent, check_mntent_file): Add better
754 support for loopback-mounted filesystems. Check /etc/mtab
755 if /proc/mounts doesn't turn up any mount flags, since
756 /etc/mtab has the loopback image filename, instead of
757 /dev/loop0. Also, check based on st_dev and st_ino, so
758 that if a relative pathname or a pathnames using symbolic
759 links are used, we can detect the the filesystem correctly
760 in those cases. (Addresses Sourceforge bug #619119)
762 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
763 don't try the FDFLUSH ioctl that was required for floppies
764 with older kernels. This avoids needless whining from the
765 MD device driver. (Addresses Sourceforge bug #545832).
767 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
768 wrong group_block to ext2fs_descriptor_block_loc if we're
769 using the backup superblock/block group descriptors.
770 (ext2fs_descriptor_block_loc): If we're using the backup
771 superblock descriptors, use the backup descriptor block in
772 the next block group.
774 2002-10-30 Theodore Ts'o <tytso@mit.edu>
776 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
777 table so that it buts up against the bitmap blocks, to
778 avoid block fragmentation.
780 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
781 bug; only allocate group descriptor blocks up to
784 2002-10-25 Theodore Ts'o <tytso@mit.edu>
786 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
787 know when a filesystem was created. (Sometimes this can
790 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
792 2002-10-20 Theodore Ts'o <tytso@valinux.com>
794 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
795 the journal data mode.
797 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
798 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
799 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
800 the meta_blockgroup filesystem format.
802 2002-10-15 <tytso@snap.thunk.org>
804 * ext2_fs.h: Add new field in superblock for default mount options.
806 2002-10-13 Theodore Ts'o <tytso@mit.edu>
808 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
811 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
813 * rw_bitmaps.c (ext2fs_write_block_bitmap,
814 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
815 because the bitmap is getting written to disk. Make
816 ext2fs_swap_bitmap be a static function, since it's not
817 intended to be exported.
819 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
821 2001-09-24 Theodore Tso <tytso@mit.edu>
823 * Release of E2fsprogs 1.29
825 2001-08-31 Theodore Tso <tytso@thunk.org>
827 * Release of E2fsprogs 1.28
829 2002-08-31 Theodore Ts'o <tytso@valinux.com>
831 * dblist.c (ext2fs_dblist_sort): New function which allows the
832 caller to pass in a special sort comparison function.
834 2002-08-20 Theodore Ts'o <tytso@mit.edu>
836 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
837 failed to accurately characterize non-standard slow
838 symlinks. (Which don't appear in practice on real-life
839 systems, fortunately.)
841 2002-08-17 Theodore Ts'o <tytso@mit.edu>
843 * Makefile.in: Remove inode_io.o from the standard object files,
844 and only build it if debugfs is enabled (it requires
845 fileio.o, which is only built if --disable-debugfs isn't
846 specified to configure).
848 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
849 incompatible way so that it is no longer
850 endian-dependent. Add the TEA hash. Allow the seed
851 parameter to be optional.
853 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
854 These features are all now in the HALF_MD4 hash. Add
855 definition for EXT2_HASH_TEA.
857 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
858 a pointer instead of an array.
860 2002-08-16 Theodore Ts'o <tytso@mit.edu>
862 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
864 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
865 the number of data blocks used by an inode exclusive of
868 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
869 adjusts the reference count in an extended attribute block.
871 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
872 correctly deal with extended attribute blocks in symbolic
875 2002-08-13 <tytso@snap.thunk.org>
877 * Makefile.in: Move dupfs.o and test_io.o from the
878 needed-by-debugfs object list to the needed-by-resizer
879 object list. Fixes compile problem if the system is built
880 with only --disable-debugfs.
882 2002-07-29 Theodore Ts'o <tytso@mit.edu>
884 * link.c (ext2fs_link): When adding a new link to a directory,
887 2002-07-23 Theodore Ts'o <tytso@mit.edu>
889 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
890 calculations for names > 32 characters to be completely
891 bogus. Changed MD4 calculation to match what is currently
892 being used in the CVS gkernel tree.
894 2002-07-19 Theodore Ts'o <tytso@mit.edu>
896 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
897 superblock definition.
899 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
900 create a set of u32_list functions.
902 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
903 since that's required by the directory indexing code.
905 2002-07-14 Theodore Ts'o <tytso@mit.edu>
907 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
908 using a C++ reserved word.
910 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
911 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
912 old version of glibc (built against 2.2 headers) will
913 interact badly with the workaround to actually cause more
914 problems. I hate it when the glibc folks think they're
915 being smarter than the kernel....
917 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
919 * ext2_fs.h: Add superblock field for reserved group descriptors.
921 2002-06-28 Theodore Ts'o <tytso@mit.edu>
923 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
924 ext2fs_cpu_to_{l,b}e{32,16}
926 2002-06-27 Theodore Ts'o <tytso@mit.edu>
928 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
929 Add appropriate fallbacks in this case.
931 2002-06-26 Theodore Ts'o <tytso@mit.edu>
933 * dirhash.c (ext2fs_dirhash): Change function signature to support
934 a hash seed, and to return the minor hash (for 64-bit hash
935 support). Add support for the half MD4, half MD4 with
936 seed, and half MD4 with seed and 64 bits.
938 2002-06-15 Theodore Ts'o <tytso@mit.edu>
940 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
942 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
944 * ext2_fs.h: Add macros for maximum block/inode counts:
945 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
946 and EXT2_MAX_INODES_PER_GROUP.
948 * openfs.c (ext2fs_open): Check that the number of blocks in a group
949 is less than 2^16, otherwise we need an INCOMPAT flag (not
950 in existence yet, if ever) to open such a filesystem.
952 * initialize.c (ext2fs_initialize): Limit the number of blocks and
953 inodes in a group to less than 2^16.
955 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
957 * ext2_fs.h: Further minor cleanups of the header. Consolidate
958 some checks for __KERNEL__ into one place.
960 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
962 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
963 the EXT2_SB() macro instead. Remove kernel function
964 prototypes also. This matches the 2.5 kernel, and
965 is also cleaner for other reasons. Whitespace cleanup.
967 2002-05-21 Theodore Ts'o <tytso@mit.edu>
969 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
971 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
973 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
975 * initialize.c (ext2fs_initialize): Remove assumption that
976 blocksizes are always <= 4k.
978 2002-05-11 Theodore Ts'o <tytso@mit.edu>
980 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
981 silently if inode pointer is NULL (and ext2fs_bmap is
982 expected to read the inode itself).
984 2002-04-27 Theodore Ts'o <tytso@mit.edu>
986 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
987 file we are checking is a block device file before looking
988 at st_rdev, since it's not valid for normal files.
989 (is_swap_device): Move so that it is outside the
990 HAVE_MNTENT_H, so that it is always built.
992 2002-03-11 Theodore Tso <tytso@mit.edu>
994 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
995 functions which take an extra flags argument. The flag
996 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
997 field is byte swampped on big-endian machines, since in
998 the V2 structure, name_len is a char field which is
999 doesn't need to be byte swapped --- except if an
1000 old-style kernel had byte-swapped the name_len field
1001 as part of the V1 structure.
1003 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
1005 * dirhash.c (ext2fs_dirhash): New function which calculates the
1006 hash for a filename in an indexed directory.
1008 2002-03-08 Theodore Tso <tytso@mit.edu>
1010 * Release of E2fsprogs 1.27
1012 2002-03-07 Theodore Tso <tytso@mit.edu>
1014 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
1016 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
1017 tst_byteswap.c: Fix gcc -Wall complaints
1019 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
1020 (From Philipp Thomas <pthomas@suse.de>)
1022 2002-02-25 Theodore Tso <tytso@mit.edu>
1024 * ext2_fs.h: Add structure definitions for the directory indexing
1027 2002-02-23 Theodore Tso <tytso@mit.edu>
1029 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
1030 it doesn't break things on mis32, sparc32, and alpha
1033 2002-02-21 Theodore Tso <tytso@mit.edu>
1035 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
1036 we were missing an fclose().
1038 2002-02-20 Theodore Tso <tytso@mit.edu>
1040 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
1041 abstraction interface which exports an ext2 inode.
1043 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
1044 as a public interface. Change void * to const void * in
1045 ext2fs_file_write's interface.
1047 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
1048 conditional; save a few bytes.
1050 2002-02-12 Theodore Tso <tytso@mit.edu>
1052 * Makefile.in (tst_badblocks): Add some extra .o files when
1053 linking the debugging program tst_badblocks which are
1054 needed if we aren't compiling with inline functions enable.
1056 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
1057 define away __inline__ since it may not be supported.
1059 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
1060 stripped down jbd_debug that doesn't use variadic
1061 arguments. This will cause warnings under AIX, but things
1064 2002-02-03 Theodore Tso <tytso@thunk.org>
1066 * Release of E2fsprogs 1.26
1068 2002-02-03 Theodore Tso <tytso@mit.edu>
1070 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
1071 so that the number of directories in use is adjusted
1074 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
1075 which optionally will modify the number of directories
1078 2002-01-03 Theodore Tso <tytso@mit.edu>
1080 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
1081 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
1082 which will return deleted directory entries.
1083 ext2fs_dir_iterate2 takes a new callback function which
1084 is identical with the one used by
1085 ext2fs_dblist_dir_iterate(). If the directory entry is
1086 deleted, the callback function will be called with the
1087 entry paraemter set to DIRENT_DELETED_FILE.
1089 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
1090 ext2fs_block_alloc_stats): New functions which update
1091 block/inode allocation statistics in the bitmaps, block
1092 group descriptors, and superblock.
1094 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
1095 expanddir.c (expand_dir_proc), bb_inode.c
1096 (clear_bad_block_proc, set_bad_block_proc,
1097 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
1098 Update to use new block/inode allocation statistics.
1100 2001-12-24 Theodore Tso <tytso@mit.edu>
1102 * ismounted.c (is_swap_device): New function used by
1103 ext2fs_check_if_mounted and ext2fs_check_mount_point which
1104 determines whether or not the specified device is a swap
1105 device by using /proc/swaps. More bulletproofing for
1106 idiotic/careless system administrators!
1108 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
1109 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
1110 field to struct_ext2_filsys, umask. This field is
1111 initialize to 022, and affects ext2fs_mkdir in the obvious
1112 way. (In the future umask should also affect new file
1113 creation routines, but the fileio functions don't
1114 currently support this yes.)
1116 * ismounted.c (check_mntent_file): Stat all of the entries in
1117 /etc/mtab and/or /proc/mounts in order to catch dim-witted
1118 system administrators who might have created alias
1121 2001-12-23 Theodore Tso <tytso@mit.edu>
1123 * Makefile.in, jfs_user.h: Move linux/jbd.h to
1124 ext2fs/kernel-jbd.h, to avoid using the system header
1125 file version of hbd.h when using diet glibc (since it
1126 forcibly adds /usr/include to the beginning of the
1127 include search path.)
1129 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
1130 include/linux directory.
1132 2001-12-16 Theodore Tso <tytso@mit.edu>
1134 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
1135 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
1136 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
1138 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
1141 2001-12-03 Theodore Tso <tytso@mit.edu>
1143 * unix_io.c (unix_open): Make sure the ulimit workaround works
1144 regardless of the version of glibc which is used to
1147 2001-11-26 Theodore Tso <tytso@mit.edu>
1149 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
1150 trying to unset the filesize limit if at all possible,
1151 if a block device is getting opened. (The filesize limit
1152 shouldn't be applied against writes to a block device, but
1153 starting in 2.4.10, the kernel is doing this.)
1155 2001-11-05 Theodore Tso <tytso@mit.edu>
1157 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
1158 file on adding a journal to an already-mounted filesystem,
1159 try to clear the ext2 file attributes on an already
1160 existing .journal file so that we don't fail if on a
1161 partially added journal to the filesystem.
1163 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
1164 which signals that a particular inode should not have the
1165 last bits of data (the "tail") be merged with another
1166 file. This is necessary to keep LILO happy.
1168 2001-09-20 Theodore Tso <tytso@thunk.org>
1170 * Release of E2fsprogs 1.25
1172 2001-09-16 Theodore Tso <tytso@mit.edu>
1174 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
1175 which was breaking the build on the Hurd. (Addresses
1176 Debian bug #112414).
1178 2001-09-13 Theodore Ts'o <tytso@mit.edu>
1180 * ismounted.c (check_mntent_file): We now validate the entry in
1181 /etc/mtab to make sure the filesystem is really mounted,
1182 since some broken distributions (read: Slackware) have
1183 buggy boot scripts that don't initialize /etc/mtab before
1184 checking non-root filesystems. (Slackware also doesn't
1185 check the root filesystem separately, and reboot if the
1186 root filesystem had changes applied to it, which is
1187 dangerous and broken.)
1189 2001-09-02 Theodore Tso <tytso@thunk.org>
1191 * Release of E2fsprogs 1.24a
1193 2001-08-30 Theodore Tso <tytso@thunk.org>
1195 * Release of E2fsprogs 1.24
1197 2001-08-30 Theodore Tso <tytso@valinux.com>
1199 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
1200 changes, since the ioctl number has been reused by another
1203 2001-08-15 Theodore Tso <tytso@valinux.com>
1205 * Release of E2fsprogs 1.23
1207 2001-08-05 Theodore Tso <tytso@valinux.com>
1209 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
1210 version of the bitmap test routines to speed up these
1211 routines. (At some point I may want to make these
1212 routines use the find_first_bit functions, but that will
1213 add a lot of complexity since it means that these
1214 functions will have to break the bitmap abstraction
1215 boundary. It's not clear it's worth it.)
1217 * mkjournal.c (mkjournal_proc): Remember the last block allocated
1218 to speed up ext2fs_new_block().
1220 2001-07-29 Theodore Tso <tytso@valinux.com>
1222 * finddev.c (scan_dir): Fix memory leak; we weren't calling
1223 closedir() when exiting the function in all cases.
1225 2001-07-27 Theodore Tso <tytso@valinux.com>
1227 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
1228 block usable in the journal for external journals to be 2
1229 or 3, depending on the blocksize, so that the existing
1230 kernel code does the right thing.
1232 * getsize.c (ext2fs_get_device_size): Add support for the
1233 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
1234 from Ben LaHaise, but it's likely this interface won't
1237 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1238 when writing the journal superblock, too. (Oops! Needed
1239 to make 1k filesystems with external journal to work.)
1241 2001-07-26 Theodore Tso <tytso@valinux.com>
1243 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1244 to find the journal superblock if the blocksize is 1024.
1246 2001-07-21 Theodore Tso <tytso@valinux.com>
1248 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
1250 2001-07-20 Theodore Tso <tytso@valinux.com>
1252 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
1253 attribute block, set the filesystem changed bit.
1255 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1256 Comment out these functions since we're not using them.
1258 2001-07-10 Theodore Tso <tytso@valinux.com>
1260 * closefs.c (write_primary_superblock): After writing changes to
1261 the primary superblock, update the original superblock
1262 copy so we don't have to re-write those changes in the
1264 (ext2fs_flush): Clear the superblock dirty flag after
1265 we've flushed out changes to disk.
1267 2001-07-07 Theodore Tso <tytso@valinux.com>
1269 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
1270 to avoid register conflicts when compiling in PIC mode.
1272 2001-07-04 Theodore Tso <tytso@valinux.com>
1274 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1275 Add new functions (C and in i386 assembler) which quickly
1276 find bits set in a bitmask.
1278 2001-06-23 Theodore Tso <tytso@valinux.com>
1280 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
1281 ext2_ext_attr.h and ext_attr.c for extended attributes
1284 * Release of E2fsprogs 1.22
1286 2001-06-22 Theodore Tso <tytso@valinux.com>
1288 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
1289 descriptor so that adding a journal to a mounted
1290 filesystem doesn't die. (Fixes a bug accidentally
1291 introduced in e2fsprogs 1.21.)
1293 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
1294 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
1295 fchflags without defining UF_NODUMP. (Addresses Debian
1298 * flushb.c: Use platform independent method of defining the
1299 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
1300 since on newer glibc's BLKFLSBUF is defined there.
1302 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
1303 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
1304 to support byte swapping even if we don't support the
1305 conversion functions. (Fixes Debian bug #101686).
1307 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
1308 since the byte-swapping code all assumes the
1309 ext2_dir_entry structure. (It's a question of whether or
1310 not name_len should be byte-swapped or not, and whether
1311 it's a 16 bit or 8 bit field.)
1313 2001-06-15 Theodore Tso <tytso@valinux.com>
1315 * Release of E2fsprogs 1.21
1317 2001-06-15 Theodore Tso <tytso@valinux.com>
1319 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
1320 file which is generated and is therefore found in the
1321 build directory, not source directory.
1323 * ismounted.c (check_mntent_file): Use a test file in / to check
1324 to see if the root filesystem is mounted read-only. This
1325 protects against the case where /etc might not be on /, as
1326 well as the case where /etc/mtab doesn't exist. (Both are
1327 should-never happen scenarios, but you never know...)
1329 2001-06-14 Theodore Tso <tytso@valinux.com>
1331 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
1332 Remove unneeded #pragma argsused, since the arguments are
1335 2001-06-13 Theodore Tso <tytso@valinux.com>
1337 * ext2_types.h.in: If linux/types.h has been defined, then don't
1338 try to redefine the typedefs.
1340 * Makefile.in (HFILES): Add ext2_types.h to the list of files
1341 which should be installed.
1343 * ismounted.c (check_mntent_file): Work around GNU hurd brain
1344 damage. Addresses Debian bug #100304.
1346 * Makefile.in: Limit some .o files from being included into the
1347 library if --disable-debugfs, --disable-swapfs,
1348 --disable-imager, or --disable-resizer are used.
1350 2001-06-12 Theodore Tso <tytso@valinux.com>
1352 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
1353 function, and use the ext2fs_badblocks_* functions
1356 2001-06-11 Theodore Tso <tytso@valinux.com>
1358 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
1359 ext2fs_mark_generic_bitmap and
1360 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
1361 functions. (This saves space and doesn't significantly
1362 change the speed of e2fsck on a P-III.)
1364 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
1365 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
1366 include the byte-swapping logic if ENABLE_SWAPFS is turned
1367 on or if we're on a big-endian machine.
1369 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
1370 set EXT2_FLAG_SWAP_BYTES, instead of using
1373 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
1374 autoconf to determine whether or not return
1375 EXT2_FLAG_SWAP_BYTES.
1377 2001-06-10 Theodore Tso <tytso@valinux.com>
1379 * Makefile.in: Remove the dependence on the libe2p library.
1381 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
1382 with direct usage of the ioctl/fchflags so that we don't
1383 have to depend on the libe2p library.
1385 2001-06-08 Theodore Tso <tytso@valinux.com>
1387 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
1388 when trying to find a 32-bit wide type.
1390 * icount.c (insert_icount_el): Fix the code used to estimate the
1391 size of the new icount array to be more intelligent, to
1392 avoid reallocating the array too many times. Thanks to
1393 Enrique Perez-Terron for pointing this out.
1395 2001-06-02 Theodore Tso <tytso@valinux.com>
1397 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
1398 for a symlink to determine whether it is a fast symlink.
1400 2001-06-01 Theodore Tso <tytso@valinux.com>
1402 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
1403 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
1405 2001-05-25 Theodore Tso <tytso@valinux.com>
1407 * Release of E2fsprogs 1.20
1409 2001-05-25 Theodore Tso <tytso@valinux.com>
1411 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
1412 some to clean up Andreas's patches. Use strncpy instead
1413 of strcpy to save the root's mountpoint. Clean up #ifdef
1414 structure. Remove uneeded variable in testing/debug driver.
1416 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
1418 * ismounted.c: Add check for root device which doesn't depend on
1419 /etc/fstab or /proc/mounts to be correct. Don't call
1420 endmntent() before we are done with mnt struct.
1422 2001-05-23 Theodore Tso <tytso@valinux.com>
1424 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
1427 2001-05-21 Theodore Tso <tytso@valinux.com>
1429 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
1430 make room for pre-existing usage of
1431 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
1432 the same codepoint as EXT2_BTREE_FL.
1434 2001-05-20 Theodore Tso <tytso@valinux.com>
1436 * ext2fs.h: #include <> instead of "" for ext2fs and et header
1437 files, since they will be installed in /usr/include
1439 2001-05-14 Theodore Tso <tytso@valinux.com>
1441 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
1442 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1443 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

1452 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
1453 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
1454 Adjust all files in this directroy to include this file.
1456 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
1459 2001-05-05 Theodore Tso <tytso@valinux.com>
1461 * fileio.c (ext2fs_file_read): Factored out common code and
1462 cleaned up function. Fixed a bug where if there was an
1463 error reading from the disk, the number of bytes read
1464 wasn't reliably set. (Fixes Debian bug #79163)
1465 (ext2fs_file_write): Factored out common code and made
1466 function more efficient; if writing a full block, don't
1467 bother to do a read-modify-write cycle.
1469 2001-05-04 Theodore Tso <tytso@valinux.com>
1471 * dirblock.c (ext2fs_read_dir_block): Check for an directory
1472 record length which isn't a multiple four, and treat that
1473 as an invalid. Scan the directory and return an error
1474 (EXT2_ET_DIR_CORRUPTED) if the directory records are
1476 (ext2fs_write_dir_block): If while byte-swapping the
1477 directory block, if there's an error, abort and return
1478 EXT2_ET_DIR_CORRUPTED.
1480 2001-05-02 Theodore Tso <tytso@valinux.com>
1482 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
1483 image_header field in the ext2_filsys structure
1485 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
1486 * inode.c (ext2fs_read_inode):
1487 * rw_bitmaps.c (read_bitmaps):
1488 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
1490 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
1491 sure the full bitmap is saved.
1493 2001-05-01 Theodore Tso <tytso@valinux.com>
1495 * e2image.h (struct ext2_image_hdr): Add space for the device name
1496 in the image header.
1498 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
1499 make sure the rec_len is a multiple of 4, to prevent
1500 bus-errors on architectures which care about mis-aligned
1503 2001-04-25 Theodore Tso <tytso@valinux.com>
1505 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
1506 query the device sizes using the BLKGETSIZE ioctl.
1508 2001-04-16 Theodore Tso <tytso@valinux.com>
1510 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
1511 before checking /etc/mtab. The EXT2_MF_READONLY flag is
1512 now set from the /etc/mtab options field for all
1513 filesystems, not just the root filesystem. Add debugging
1514 code to make it easier to test ext2fs_check_if_mounted().
1516 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
1517 check; return an error if there's an attempt to create a
1518 journal less than 1024 filesystem blocks.
1520 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
1521 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
1523 2001-02-20 Theodore Tso <tytso@valinux.com>
1525 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
1528 * tst_byteswap.c: New function to test the byteswap functions.
1529 Add to regression test suite.
1531 2001-02-08 Theodore Tso <tytso@valinux.com>
1533 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
1535 2001-02-07 Theodore Tso <tytso@valinux.com>
1537 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
1538 of s_first for external devices to always be 1, since
1539 jsb->s_first is always relative to the start of the
1540 journal superblock. Use htonl(1) when setting s_nr_users.
1542 2001-01-17 Theodore Ts'o <tytso@valinux.com>
1544 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
1545 device number of the filesystem (instead of the journal)
1546 was being dropped into s_journal_dev.
1548 2001-01-15 Theodore Ts'o <tytso@valinux.com>
1550 * initialize.c (ext2fs_initialize): Add support for initializing
1551 the ext2 superblock for external journal devices. This
1552 basically means we don't bother to allocate any block
1555 * openfs.c (ext2fs_open): Only open external journal devices if
1556 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
1557 ext2fs_open. When opening such devices, don't try to read
1558 the block group descriptors, since they're not there.
1560 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
1562 * mkjournal.c: Export a new function,
1563 ext2fs_create_journal_superblock(), which allocates and
1564 returns a buffer containing a journal superblock. This is
1565 needed by mke2fs to create an external journal. Rewrote
1566 ext2fs_add_journal_device() so that it no longer creates
1567 the external journal, but rather adds a filesystem to an
1568 existing external journal. It handles all of the UUID
1571 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
1572 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
1573 Changed function prototype for ext2fs_add_journal_device().
1575 2001-01-14 Theodore Ts'o <tytso@valinux.com>
1577 * closefs.c (ext2fs_flush): Don't write out anything beyond the
1578 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
1581 2001-01-12 Theodore Ts'o <tytso@valinux.com>
1583 * imager.c: Fix gcc -Wall complaints and a series of bugs where
1584 retval wasn't set correctly. (Thanks to Andreas Dilger
1585 for pointing this out.)
1587 2001-01-11 <tytso@snap.thunk.org>
1589 * flushb.c (ext2fs_sync_device): New function which centralizes
1590 all of the places which might try to use the BLKFLSBUF
1591 or FDFLUSH ioctls (and usually failing to define them
1592 since the system header files don't usually do this for
1593 us, and we're trying to avoid usage of kernel include
1596 2001-01-10 <tytso@snap.thunk.org>
1598 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
1599 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
1600 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
1601 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
1602 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
1603 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
1604 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
1605 ext2_ino_t, to protect applications that attempt to
1606 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
1607 changes ino_t(!?). So we use ext2_ino_t to avoid an
1608 unexpected ABI change.
1610 2001-01-05 <tytso@snap.thunk.org>
1612 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
1613 we may overrun allocated memory in case of a corrupted
1614 filesystem (or an e2fsck test case :-) when byte-swapping
1615 the directory block.
1617 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
1619 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
1620 complaints including a missing return 0 at the end of
1621 ext2fs_add_journal_device.
1623 2001-01-03 <tytso@snap.thunk.org>
1625 * Makefile.in: Link in libe2p when creating libext2fs as a shared
1626 library, since mkjournal.c now references fsetflags().
1628 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
1629 Dilger's changes (with fixups) to allow on-line creation
1632 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
1633 EXT2_FLAG_SUPER_ONLY, which the close routines to only
1634 update the superblock, and not the group descriptors.
1636 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
1638 * ismounted.c: add ext2fs_check_mount_point() function, which will
1639 optionally return the mount point of a device if mounted
1641 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
1643 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
1644 ext2fs_add_journal_inode()
1646 2001-01-01 <tytso@snap.thunk.org>
1648 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
1649 source (but not binary) compatibility of some users of the
1650 ext2 library. They should just simply do a global search
1651 and replace of struct ext2fs_sb with struct
1652 ext2_super_block, and use their own private copy of
1653 ext2_fs.h if they aren't already.
1655 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
1656 Replace use of ext2fs_sb with ext2_super_block.
1658 2000-12-31 <tytso@snap.thunk.org>
1660 * ext2fs.h: Cleaned up header file by removing definitions of
1661 feature flags that might not have been defined in older
1662 ext2 header files. Now that we're using our own
1663 include/linux/ext2fs.h header file, this can never happen.
1665 * jfs_dat.h: Removed old header file which is no longer needed.
1667 2000-12-13 Theodore Ts'o <tytso@valinux.com>
1669 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
1670 by Andreas Dilger to update the filesystem revision to
1673 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
1676 2000-12-09 <tytso@snap.thunk.org>
1678 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
1679 ext2fs_add_journal_device): Add a new argument to the APIs
1680 of these function, which is a flags word. This is used to
1681 allow the creation of a V1 superblock for those folks who
1682 are using ext3 0.3b in production. Note, the user-land
1683 interface for getting at this flag won't be documented, as
1684 the V1 superblock is deprecated.
1686 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
1687 which creates a V2 superblock instead of a V1 superblock.
1689 2000-11-21 <tytso@snap.thunk.org>
1691 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
1692 out by Andreas Dilger.
1694 2000-11-05 <tytso@snap.thunk.org>
1696 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
1697 ext2_fs.h, Makefile.in: New file that has routines that
1698 save ext2fs metadata to a file.
1700 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
1702 * e2image.h: New file which defines the file format for the ext2
1703 image file. (Saved copy of ext2 metadata to a file as a
1704 saving throw against worst-case damage.)
1706 2000-11-01 <tytso@snap.thunk.org>
1708 * inode.c (ext2fs_flush_icache): Add new function
1709 ext2fs_flush_icache() which flushes the internal inode
1710 cache. Applications which modify the inode table blocks
1711 directly must call this function.
1713 2000-10-26 <tytso@snap.thunk.org>
1715 * mkjournal.c: Add #include of netinet/in.h, since Solaris
1716 requires it for ntohl().
1718 * ext2_io.h (io_channel_write_byte): Add new interface to allow
1719 callers to write specific byte ranges. This is an
1720 optional interface, which not all IO channels may
1723 * unix_io.c (unix_write_byte):
1724 * test_io.c (test_write_byte): Add implementation of the
1725 write_byte function.
1727 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
1728 function which writes the primary superblock. If the IO
1729 channel supports writing raw bytes directly, only fields
1730 which were modified are written to the disk. This makes
1731 it safe(r) to use utilities like tune2fs on a mounted
1734 * freefs.c (ext2fs_free): Free the original superblock if it is
1737 * openfs.c (ext2fs_open): Store a copy of the original superblock
1740 * ext2fs.h: Add a field to store the original superblock in the
1741 ext2 context structure.
1743 2000-10-24 <tytso@snap.thunk.org>
1745 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
1746 don't need to use llseek).
1748 2000-10-24 <tytso@valinux.com>
1750 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
1751 creating an ext3 journal on a filesystem.
1753 2000-08-21 <tytso@valinux.com>
1755 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
1757 2000-08-22 <tytso@valinux.com>
1759 * unix_io.c: Make massive changes to support a multiple block
1760 writethrough cacheing.
1762 * ext2_io.h: Added flags field to the io_channel structure.
1764 2000-08-19 <tytso@valinux.com>
1766 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
1767 provides the function ext2fs_find_block_device(). This
1768 function returns the pathname to a block device, given its
1771 2000-07-13 <tytso@valinux.com>
1773 * Release of E2fsprogs 1.19
1775 2000-07-07 Theodore Ts'o <tytso@valinux.com>
1777 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
1778 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
1779 list of filesystem flags supported by the library.
1781 2000-07-04 Theodore Ts'o <tytso@valinux.com>
1783 * ext2fs.h: Update to include latest journalling additions to the
1786 * dll/jump.funcs: Add new jumptable entries for
1787 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1788 ext2fs_badblocks_equal.
1790 * tst_badblocks.c: Update test program to test
1791 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
1793 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
1794 writes out bad blocks list to a file.
1796 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
1797 changes the callback function to take two additional
1798 arguments; a private blind pointer supplied by the caller,
1799 and pointer to a char * containing a pointer to the
1802 * badblocks.c (ext2fs_badblocks_equal): Add new function which
1803 returns true if two badblocks list are equal.
1805 * Makefile.in: Remove explicit link of -lc in the shared library.
1806 (It shouldn't be necessary, and is harmful in some cases).
1808 2000-06-10 Theodore Ts'o <tytso@valinux.com>
1810 * getsize.c (main): Add debugging code under #ifdef DEBUG
1812 2000-05-27 Theodore Ts'o <tytso@valinux.com>
1814 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
1815 earlier, so that if there's an error reading it, we can
1816 more cleanly back out of the operation.
1818 2000-05-25 <tytso@snap.thunk.org>
1820 * getsize.c (ext2fs_get_device_size): Use open64() instead of
1821 open() if it exists. Under linux, manually define the
1822 ioctl for BLKGETSIZE if it isn't already defined and it's
1825 * unix_io.c (unix_open): Use open64() instead of open() if it
1828 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1829 available (and prototypes are defined) use it in
1830 preference to llseek.
1832 * Makefile: Add hack dependency rule so that parallel makes work
1835 2000-05-18 Theodore Ts'o <tytso@valinux.com>
1837 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
1839 2000-04-03 Theodore Ts'o <tytso@valinux.com>
1841 * block.c: Readibility tweak in conditionals involving
1844 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
1845 how to define __s64 and __u64. Turn off "compression is
1846 experimental" warning if the cpp macro
1847 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
1849 2000-02-11 <tytso@snap.thunk.org>
1851 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
1852 Conditionally include Compression as a supported type if
1853 ENABLE_COMPRESSION (via --enable-compression) is turned on.
1855 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
1857 2000-02-08 <tytso@snap.thunk.org>
1859 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
1860 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1861 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
1862 Change to return the previous state of the bit that is
1863 being marked or unmarked. For speed optimization.
1865 2000-02-02 Theodore Ts'o <tytso@valinux.com>
1867 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
1869 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
1870 needed any more; we know it will always be i_generation.
1871 Add support for swapping the high bits of the uid and gid.
1873 1999-11-19 <tytso@valinux.com>
1875 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1876 counts if the link was successful. Patch suggested by
1879 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
1880 the source directory.
1882 1999-11-10 <tytso@valinux.com>
1884 * Release of E2fsprogs 1.18
1886 1999-11-08 <tytso@valinux.com>
1888 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1889 since ext2fs_badblocks_list_free was moved to freefs.c.
1891 * tst_badblocks.c: Use the newer badblocks API names. Add
1892 duplicate blocks to the test inputs to test dealing with
1893 adding blocks which are already in the badblocks list.
1895 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1896 of the list, use a shortcut O(1) operations instead of an
1897 O(n) operation. (Idea suggested by David Beattie.)
1899 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1900 of badblocks_list_free(), to save a procedure call.
1902 1999-10-26 <tytso@valinux.com>
1904 * Release of E2fsprogs 1.17
1906 1999-10-26 <tytso@valinux.com>
1908 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1909 seem to handle ~0UL the same way as they used to.
1911 1999-10-25 <tytso@valinux.com>
1913 * nt_io.c (_OpenNtName): Open the device using
1914 FILE_SYNCHRONOUS_IO_NONALERT instead of
1915 FILE_SYNCHRONOUS_IO_ALERT
1916 (nt_open): At the end of the device open routine, unlock
1917 the drive but do not dismount it.
1919 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
1922 1999-10-22 <tytso@valinux.com>
1924 * Release of E2fsprogs 1.16
1926 1999-10-22 <tytso@valinux.com>
1928 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1930 * link.c (ext2fs_link): This call now uses the low three bits of
1931 the flags parameter to pass the directory filetype
1932 information; it will set the directory entry FILETYPE
1933 information if the filesystem supports it.
1935 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1936 option is set, then create the '.' and '..' entries with
1937 the filetype set to EXT2_FT_DIR.
1939 1999-09-24 <tytso@valinux.com>
1941 * nt_io.c: New file which supports I/O under Windows NT.
1943 1999-09-07 <tytso@valinux.com>
1945 * ext2fs.h: Add new fields for journalling and define new
1946 feature bits used by newer filesystems: IMAGIC_INODES,
1947 HAS_JOURNAL, RECOVER.
1949 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1950 we update the inode block count and size files so that the
1951 block count field is updated correctly when we create an
1954 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1956 * Release of E2fsprogs 1.15
1958 1999-06-23 <tytso@valinux.com>
1960 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1961 kernels that use i_generation instead of i_version. Patch
1962 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1964 1999-06-21 <tytso@valinux.com>
1966 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1967 directory entry before calling the callback function.
1968 This should prevent some core dumps of insufficiently
1969 paranoid callback functions.
1971 1999-05-29 <tytso@rsts-11.mit.edu>
1973 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1975 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1976 that we don't handle writing yet (we do). Fixed bug where
1977 we weren't allocating a big enough buffer for ext2_bmap.
1979 1999-05-03 <tytso@rsts-11.mit.edu>
1981 * openfs.c (ext2fs_open): Check to make sure that the number of
1982 blocks per group is not zero --- if so, it must be a bad
1985 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1987 * Release of E2fsprogs 1.14
1989 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1991 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1992 the inode number is zero; if it's zero, return
1993 EXT2_ET_BAD_INODE_NUM.
1995 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1997 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1998 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
2001 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
2003 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
2004 non-Linux case to use EINVAL by default, unless it isn't
2005 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
2008 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
2010 * Release of E2fsprogs 1.13
2012 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
2014 * Makefile.in: Updated dependencies.
2016 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
2018 * initialize.c (ext2fs_initialize): Make sure that we allocate
2019 enough inodes so that we can make a valid filesystem.
2021 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
2023 * rw_bitmaps.c: Fixed signed/unsigned warnings.
2025 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
2026 function declaration.
2028 * dblist.c (make_dblist): Add safety check in case the dblist
2029 pointer passed in is null (in which case, assign it to
2030 fs->dblist). Fixed some signed/unsigned warnings.
2032 * bmap.c: Make addr_per_block be of type blk_t to avoid
2033 signed/unsigned warnings.
2035 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
2036 function declaration.
2038 * get_pathname.c (get_pathname_proc): Use return value from
2039 ext2fs_get_mem, instead of checking if &gp->name is
2042 * dir_iterate.c (ext2fs_process_dir_block):
2043 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
2044 from the function declaration.
2046 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
2047 return the error directly instead of jumping to the
2048 cleanup routine, since we don't need to do any cleanup.
2050 * alloc_table.c (ext2fs_allocate_group_table): Make this
2051 function take a dgrp_t for its group argument.
2053 * ext2fs.h: Make dgrp_t an __u32 type, and make
2054 fs->desc_group_count be of type dgrp_t.
2056 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
2058 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
2059 than 10 blocks when we need to expand the size of the
2062 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2064 * Release of E2fsprogs 1.12
2066 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2068 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
2069 appropriate for all of the block group copies, so that
2070 it's clear where the beginning of the filesystem is on the
2071 disk. (For when the partition table gets scrod.)
2073 * ext2fs.h: Change the name of the feature from
2074 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
2075 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
2077 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
2079 * inode.c (get_next_blockgroup): Fix bug where if
2080 get_next_blockgroup() is called early because of a missing
2081 inode table in a block group, the current_inode counter
2082 wasn't incremented correctly.
2084 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
2086 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
2087 against a completely trashed bad block inode.
2089 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
2091 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
2092 the stride length hits a bad value, we retry the block
2093 allocation starting at the beginning of the block group.
2095 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
2096 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
2097 e2_blkcnt_t to avoid collision with LFS API.
2099 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
2101 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
2102 way that avoids overflows on disk sizes greater than 4GB.
2104 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
2106 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
2107 return type for comparison functions for qsort.
2109 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
2112 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
2114 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
2117 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
2118 evade a potential problem with glibc's header files trying
2119 to spike out linux/types.h.
2121 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
2122 include the old size of the memory, which is needed for
2123 some braindamaged memory allocation systems that don't
2126 * badblocks.c (ext2fs_badblocks_list_add):
2127 bb_inode.c (clear_bad_block_proc):
2128 dblist.c (ext2fs_add_dir_block):
2129 icount.c (insert_icount_el):
2130 irel_ma.c (ima_put):
2131 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
2132 pass the old size of the memory to be resized to
2133 ext2fs_resize_mem().
2135 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2137 * Makefile.in: Change to use new installation directory variables
2138 convention. Fix uninstall rules to take $(DESTDIR) into
2141 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
2143 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
2144 with 32 bit longs, then we need to manually define __s64
2145 and __u64, since the current kernel header files don't
2146 define these if __STRICT_ANSI__ is defined. This is a
2147 problem if we are compiling with full GCC warnings, since
2148 we do need 64 bit support.
2150 * Makefile.in (OBJS): Remove bmove.o from files to be built,
2151 since we're not using ext2fs_move_blocks() and there
2152 is some question as to its usefulness in its current
2155 * bmap.c (block_bmap): Remove unused function.

2161 * block.c (ext2fs_block_iterate3): Make the ref_offset field
2162 contain the offset into the inode.i_blocks array when
2163 ref_block is zero. Since we haven't done a formal

2165 introduced, I removed block_iterate2, and renamed
2166 block_iterate3 to be block_iterate2.
2168 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
2169 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change

2181 the library to declare that we support COMPAT_DIR_PREALLOC,
2182 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
2184 * fileio.c: Rename function ext2fs_file_llseek to be
2185 ext2fs_file_lseek, which is more accurate.
2187 * block.c: Add new function ext2fs_block_iterate3 which calls
2188 the iterator function with the blockcount argument of
2189 type blkcnt_t. This version of the function is
2190 allowed to handle large files; the other fucntions are
2193 * ext2fs.h: Add new type blkcnt_t
2195 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
2197 * block.c (ext2fs_block_iterate2): Fix bug where the block count
2198 field wasn't getting correctly incremented for sparse

2261 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
2262 so that we don't need to call get_next_blockgroup() the
2263 first time around. Saves a bit of time, and prevents us
2264 from needing to assign -1 to current_group (which is an
2267 * icount.c (insert_icount_el): Cast the estimated number of inodes
2268 from a float to an ino_t.

2307 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2309 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
2310 paranoid about validating the directory counts from the
2311 block group information.
2313 * all files: Don't include stdlib.h anymore; include it in
2314 ext2_fs.h, since that file requires stdlib.h
2316 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2318 * expanddir.c (ext2fs_expand_dir): Check to make sure the block

2441 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
2442 filesystem has its bitmaps stored as 32-bit words with bit
2443 0 as the LSB of each word. Thus a bitmap with only bit 0
2444 set would be, as a string of bytes, 00 00 00 01 00 ... To
2445 cope with this, we byte-reverse each word of a bitmap if
2446 we have a big-endian filesystem, that is, if we are *not*
2447 byte-swapping other word-sized numbers.

2567 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
2568 ext2fs_badblocks_list_test would test the list (and exceed
2569 array boundaries) if there were no bad blocks on the bad
2570 blocks list. (Showed up when user tried: mke2fs -c -b 4096).

2662 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
2663 overhead calculation was accidentally removed.
2665 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2667 * Release of E2fsprogs version 1.08
2669 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2671 * dblist.c (ext2fs_set_dir_block): New function which sets the
2672 block of a dblist entry, given the directory inode and
2675 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2677 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
2678 inode bitmaps at staggered locations across the block
2679 groups, to avoid concentrating the bitmaps on a small
2680 number of disks when using striped RAID arrays.
2682 * initialize.c (ext2fs_initialize): By default, choose the maximum
2683 possible number of blocks per group (based on the size of
2684 the bitmaps in the blocksize).
2686 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2688 * initialize.c (ext2fs_initialize): Add support for
2689 EXT2_COMPAT_SPARSE_SUPER feature.
2691 * closefs.c (ext2fs_bg_has_super): New function to determine
2692 whether or a particular block group should have a
2693 superblock and block group descriptor. Used for the
2694 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
2695 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
2696 or not the superblock should be written out for the block
2699 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
2700 for sparse duplicate superblocks.
2702 * version.c (ext2fs_get_library_version): New function which
2703 returns the library version.
2705 * version.c (ext2fs_parse_version_string): New function which
2706 parses a version string and returns a version number,
2707 so application programs can compare version numbers as
2710 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2712 * icount.c (ext2fs_create_icount): Change function so that it also
2713 takes a new argument which contains a "hint" icount
2714 structure. This "hint" icount allows the create function
2715 to set up the sorted list in advance. This reduces
2716 significantly the amount of data moving needed to insert
2717 these inodes into the list later.
2719 * icount.c (ext2fs_icount_validate): New function which validates
2720 that the icount structure's rep invariant.
2722 * icount.c (get_icount_el): Completely revamped implementation
2723 to subsume put_icount_el(). Put_icount_el() used to
2724 use an O(N) implementation to insert in the middle
2725 of the icount list. It now uses a O(ln N) to search
2726 for where the icount should be inserted, and then uses
2727 a memcpy to move the list down (instead of a for loop).
2729 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
2730 ext2fs_icount_increment, ext2fs_icount_decrement): Check
2731 to see if the inode is within bounds; if it isn't, return
2734 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
2735 when a bad inode number is passed to test_generic_bitmap
2736 to be EXT2FS_TEST_ERROR instead of the wrong
2737 EXT2FS_UNMARK_ERROR.
2739 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
2741 * Release of E2fsprogs version 1.07
2743 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2745 * Makefile.in (ELF_VERSION): Change version to be 2.2
2747 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2749 * alloc.c (ext2fs_get_free_blocks): Change routine to use
2750 ext2fs_fast_test_block_bitmap_range().
2752 * bitops.h (ext2fs_fast_test_block_bitmap_range,
2753 ext2fs_test_block_bitmap_range: New inline functions which
2754 test to see whether a contiguous range of blocks is
2757 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2759 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
2760 use ext2fs_badblocks_* instead of badblocks_*
2762 * bb_compat.c: New file which translates between old badblocks_*()
2763 names to ext2fs_badblocks_*()
2765 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
2766 link.c (since e2fsck doesn't use ext2fs_unlink()).
2768 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
2769 bitmap resizing routine moved from bitmaps.c, since e2fsck
2770 doesn't need to use this function.
2772 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
2773 since e2fsck only needs ext2fs_lookup.
2775 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2777 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
2778 already set; this is needed so that programs like dump
2779 which use the inode scan functions will deal with
2780 filesystems that have bad blocks in the inode table.
2782 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2784 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
2785 Moved to ext2fsP.h, since it doesn't need to be part of
2786 the public interface.
2788 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
2790 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2792 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
2793 directory block list abstraction. (Code moved from
2796 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
2797 to inode.c (since no one else should be peeking inside it!)
2799 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
2801 * openfs.c (ext2fs_open): Check the feature set in the ext2
2802 superblock, and refuse to open filesystems if they contain
2803 incompatible features. (Can be overriden with the
2806 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2808 * block.c (ext2fs_block_iterate2): Added new function
2809 ext2fs_block_iterate2 which changes the function
2810 signature of the callback function to include the
2811 referencing block and offset.
2813 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
2814 ext2fs_inode_scan_goto_blockgroup which allows an
2815 application to jump to a particular block group while
2816 doing an inode scan.
2818 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2820 * dirblock.c: Include string.h, since we use memcpy().
2822 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2824 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2825 a long not an int; this doesn't matter on i386 machines,
2826 but it does on Alpha's.
2828 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2830 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2831 table pointer is NULL, then return an error indicating
2832 that the inode table is missing.
2833 (get_next_blockgroup, get_next_blocks,
2834 ext2fs_get_next_inode): Don't treat a missing inode table
2835 as permanent error. Return MISSING_INODE_TABLE, but as an
2836 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
2838 * rw_bitmaps.c (ext2fs_write_block_bitmap,
2839 ext2fs_write_inode_bitmap): If the inode or block bitmap
2840 block is zero, then don't write out the inode or block
2841 bitmap. The idea here is to avoid stomping on the
2843 (read_bitmaps): If the inode or block bitmap block is
2844 zero, then fill in that portion of the inode or block
2845 bitmap with all zeros.
2847 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
2848 blocks in inode table when the inode table size is
2849 non-standard (and can therefore span blocks).
2851 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2853 * alloc.c (ext2fs_new_block): Fix fencepost error in
2854 ext2fs_new_block; make sure we don't try to allocate the
2855 first block beyond the end of the filesystem.
2857 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2859 * inode.c (check_for_inode_bad_blocks): New function called by
2860 get_next_blocks() to avoid reading in bad blocks marked in
2861 fs->badblocks. Inodes located in bad blocks are returned
2862 by ext2fs_get_next_inode() returns the error code
2863 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
2865 * alloc_tables.c (ext2fs_allocate_tables): New function which
2866 performs the part of mke2fs's job of allocating the
2869 * test_io.c (test_close): IO manager which is used for testing
2872 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2874 * inode.c (ext2fs_get_next_inode): Separate out the function of
2875 setting up for a new block group to get_next_blockgroup().
2876 Separate out the function of reading in blocks of the
2877 inode table to get_next_blocks().
2879 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
2881 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2882 blocks to the badblock list in sorted order. This allows
2883 badblocks_list_test to be coded using a binary search for
2886 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2888 * Release of E2fsprogs version 1.06
2890 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2892 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2893 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2896 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2897 set, then only write out the master superblock.
2899 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2901 * block.c (ext2fs_block_iterate): Fixed bug which caused
2902 block_iterate to fail to handle HURD created filesystems;
2903 it tested the inode translator field before the inode was
2906 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2908 * initialize.c (ext2fs_initialize): Make sure the description for
2909 the inode bitmap is set correctly.
2911 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

2915 * Release of E2fsprogs version 1.05
2917 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2924 * namei.c (ext2fs_namei_follow): New function which follows
2925 symbolic link (if any) at the target.
2927 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2929 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2930 for shortcut function fs->read_inode() and fs->write_inode().
2931 Added inode_cache to reduce CPU time spent in doing
2934 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
2937 * namei.c (ext2fs_follow_link): New function.
2938 (ext2fs_namei): Extended to have support for chasing
2939 symbolic links. ext2fs_namei() still returns an inode
2940 which is a symbolic link. Symbolic links are only chased
2941 while resolving the containing directory. To chase
2942 symbolic links of the final result, use
2943 ext2fs_follow_link().
2945 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2947 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2949 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2950 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

2954 * initialize.c (ext2fs_initialize): On systems where the byte
2955 order is not i386 compatible, set the swap_byte flag.
2957 * inode.c (inocpy_with_swap): Check to see if inode contains a
2958 fast symlink before swapping the inode block fields. This
2959 required adding a new argument to inocpy_with_swap to
2960 determine whether the mode field is in host order or not.
2962 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2964 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2965 the sparc, if EXT2_STD_BITOPS set, use the standard
2966 i386-compatible bitmask operations, instead on the
2967 non-standard native bitmask operators.
2969 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2971 * block.c (ext2fs_block_iterate): Cause block iterator to return
2972 the HURD translator block (along with everything else).
2973 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2974 iterator, then don't return any meta data blocks
2975 (including the HURD translator).
2977 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2979 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2981 * uuid.c: New file, containing UUID utility functions.
2983 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2985 * ext2fs.h: Add a definition of the "real" ext2 superblock.
2987 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2989 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
2991 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2993 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2994 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2995 that's a basic value that must be correct for the rest of
2996 the library to work.
2998 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
3001 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3003 * Release of E2fsprogs version 1.04

3007 * Release of E2fsprogs version 1.03
3009 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
3011 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
3012 Change the m68k bit numbering for bitmasks to match with
3013 the bit numbering used by all other ext2 implementations.
3015 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
3017 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

3031 the passed in size is *really* too small.
3033 * alloc.c (ext2fs_new_inode):
3034 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
3037 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
3039 * getsize.c (ext2fs_get_device_size): Open the device read-only
3040 when trying to determine its size.
3042 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
3044 * Release of E2fsprogs version 1.02

3050 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3051 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
3052 to avoid conflicts with with kernel include files. Also
3053 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
3056 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
3058 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c

3078 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
3081 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>

3084 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
3086 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
3088 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
3090 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
3093 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
3095 * getsize.c (ext2fs_get_device_size): Add support for reading the

3098 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3100 * getsize.c (ext2fs_get_device_size): New function that determins
3101 the size of a device. Used by mke2fs and e2fsck.
3103 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
3105 * Makefile.in (install): Install static libraries in $(ulibdir)
3106 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
3108 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
3110 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
3111 Move these functions to freefs.c.
3113 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
3114 descriptors shadow memory to keep purify quiet. (This
3115 also has the nice benefit that the unused portion of the
3116 shadow descriptors are zeroed out.)
3118 * dirblock.c (ext2fs_write_dir_block): We need to use
3119 dirent->rec_len *before* it's byteswapped to find the
3120 location of the next directory structure!
3122 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
3123 cause ext2fs_new_inode to loop infinitely if we're trying
3124 to allocate an inode in group #0 and there are no free
3125 inodes at all in the system.
3127 * closefs.c: #include <errno.h> if it exists.
3129 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

3148 file containing functions for reading and writing
3149 directory blocks (byte swapping if necesssary)
3151 * block.c (block_iterate_ind, block_iterate_dind,
3152 block_iterate_tind): Byte swap the block addresses if
3153 EXT2_SWAP_BYTES is set (and swap them back before writing
3156 * inode.c (inocpy_with_swap): New function.
3157 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
3158 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
3160 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
3161 the superblock and group descriptors before writing it out.
3163 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
3164 then set the EXT2_SWAP_BYTES and byte-swap the superblock
3165 and group descriptors.
3167 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
3168 to desp ext2 filesystem structures.
3170 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
3171 supplied by Pete A. Zaitcev so that the C language
3172 versions of these functions are more portable. They will
3173 now work on both little and big endian systems, and the
3174 assumption that 32-bit integers are used is gone.
3176 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
3177 doing byte swapping.
3179 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
3180 byte swapping should take place.
3182 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
3184 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,

3186 containing routines to compare bitmaps.
3188 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
3189 Added new error codes.
3191 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
3193 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
3194 if the magic number is correct, it will be allocated.
3196 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
3198 * block.c (block_iterate_ind, block_iterate_dind,
3199 block_iterate_tind): Don't recompute block_nr each loop;
3200 just increment it! Factor check of BLOCK_FLAG_APPEND out
3201 of the loop. Factor mask of BLOCK_CHANGED into changed
3202 variable out of the loop. (block_iterate_ind, in
3203 particular, gets called a lot, so every little
3204 optimization helps.)
3206 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
3208 * block.c (block_iterate_ind, block_iterate_dind,
3209 block_iterate_tind): Precompute limit of loop to speed up
3210 block_iterate_ind and company.
3212 * bitops.h (ext2fs_fast_mark_block_bitmap,
3213 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
3214 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
3215 ext2fs_fast_test_inode_bitmap): Add fast version of these
3216 functions, which don't do range checking.
3218 * bitops.h (ext2fs_get_block_bitmap_start,
3219 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
3220 ext2fs_get_inode_bitmap_end): Add new accessor functions
3221 which return the start and end points of the bitmaps.
3223 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
3225 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
3226 instead of llseek. The errno if the offset is too large
3227 and lseek is not supported should be EINVAL, not -EINVAL.
3229 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
3231 * Makefile.in: Added support for ELF shared libraries.
3232 Fixed typos in the compilation rules.
3233 (distclean): Added Makefile.
3235 * llseek.c (llseek): New function, if llseek() does not exist in the
3237 (ext2_llseek): Changed to call llseek().
3239 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3241 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
3243 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3245 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
3247 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
3248 the S_*, which are normally defined in <sys/stat.h>. This
3249 allows us to compile e2fsprogs on a non-Linux system,
3250 which may have a different value for S_IFDIR.
3252 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3254 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
3255 this is a user-mode application!
3257 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
3259 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
3260 __linux__ so that non-linux systems won't see it.
3262 * alloc.c: Include <errno.h> if possible.
3263 * badblocks.c: Ditto.
3264 * bb_inode.c: Ditto.
3267 * expanddir.c: Ditto.
3268 * get_pathname.c: Ditto.
3269 * initialize.c: Ditto.
3276 * rw_bitmaps.c: Ditto.
3279 * Makefile.in: Rewritten to conform to GNU coding standards and
3280 support separate compilation directories.
3282 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
3284 * initialize.c (ext2fs_initialize): Don't allow more than one
3285 bitmaps's worth of inodes in a group.
3287 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
3289 * llseek.c (ext2_llseek): Added error checking to the llseek()
3290 compat code to protect against overflow. This only
3291 applies to 1.0 and early 1.1 kernels, which don't support
3292 the llseek() system call.
3294 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
3296 * unix_io.c (unix_open): Initialize the read_error and write_error
3297 io_channel pointers to be null.
3299 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
3300 found, clear it but don't try to update the filesystem
3301 accounting information, since that's hopeless anyway.
3303 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
3304 bloblock_iterate_tind): Check to see if the indirect blocks are
3305 valid before trying to read them.
3307 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
3308 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
3310 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
3311 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
3312 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
3313 illegal block or inode number is passed in, return instead
3314 of trying to test, set, or clear the bit.
3316 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
3318 * Makefile: Added a dummy install target in case shared libraries
3321 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
3323 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
3324 the real last block of the bitmap should be calculated.
3326 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
3328 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
3329 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
3330 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
3331 ext2fs_free_block_bitmap): Add magic number checking for
3332 the inode and block bitmaps.
3334 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
3335 magic number for a block bitmap instead of an inode bitmap.
3337 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
3338 magic number checking for the inode_scan structure.
3340 * badblocks.c (badblocks_list_free, badblocks_list_add,
3341 badblocks_list_test, badblocks_list_iterate_begin,
3342 badblocks_list_iterate, badblocks_list_iterate_end): Add
3343 magic number checking for the badblocks_list and
3344 badblocks_iterate structures.
3346 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
3347 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
3348 unix_write_blk, unix_flush): Add magic number checking
3349 both for io_channel structure and unix_private_data
3352 * openfs.c (ext2fs_open): Add check for io_manager structure's
3355 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
3356 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
3357 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
3358 * read_bb.c (ext2fs_read_bb_inode):
3359 * read_bb_file.c (ext2fs_read_bb_FILE):
3360 * newdir.c (ext2fs_new_dir_block):
3361 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
3362 * link.c (ext2fs_link, ext2fs_unlink):
3363 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

3370 ext2fs_allocate_block_bitmap):
3371 * bb_inode.c (ext2fs_update_bb_inode):
3372 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
3373 * check_desc.c (ext2fs_check_desc):
3374 * closefs.c (ext2fs_close, ext2fs_flush):
3375 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
3380 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
3381 openfs.c into its own file.
3383 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
3384 structure magic numbers.
3386 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
3387 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
3388 someone uses the -b option to specify the use of the backup
3389 superblock --- this usually means that the main superblock is
3393 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
3394 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
3395 revision level to the superblock.
3397 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
3404 * initialize.c: Completely revamped the inode and block bitmap
3405 structures, so that they can be better chance of being extensible
3406 in a shared library. They are now their own type, instead of
3407 being a char *. Also, the function signatures of
3408 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
3409 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
3410 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
3411 changed to eliminate the ext2_filsys argument, since it is no
3414 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
3416 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
3417 system call if available.
3419 * llseek.c: new file. This is the stub calling the llseek system
3420 call which allows supports for 2GB+ file systems.
3422 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
3423 the creator operating system.
3425 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
3427 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
3428 the group descriptor statistics in addition to everything else.
3429 This relieves mke2fs of the responsibility of doing it.
3431 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
3432 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
3433 not the generic C function equivalents should be included or not.
3435 * openfs.c (ext2fs_open): If a superblock is specified, then use
3436 the backup group descriptors that go along with this superblock,
3437 instead of using the primary group descriptors. This allows
3438 e2fsck to recover filesystems where the primary group descriptors
