1 2001-06-22 Theodore Tso <tytso@valinux.com>
3 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
4 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
5 fchflags without defining UF_NODUMP. (Addresses Debian
8 * flushb.c: Use platform independent method of defining the
9 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
10 since on newer glibc's BLKFLSBUF is defined there.
12 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
13 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
14 to support byte swapping even if we don't support the
15 conversion functions. (Fixes Debian bug #101686).
17 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
18 since the byte-swapping code all assumes the
19 ext2_dir_entry structure. (It's a question of whether or
20 not name_len should be byte-swapped or not, and whether
21 it's a 16 bit or 8 bit field.)
23 2001-06-15 Theodore Tso <tytso@valinux.com>
25 * Release of E2fsprogs 1.21
27 2001-06-15 Theodore Tso <tytso@valinux.com>
29 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
30 file which is generated and is therefore found in the
31 build directory, not source directory.
33 * ismounted.c (check_mntent_file): Use a test file in / to check
34 to see if the root filesystem is mounted read-only. This
35 protects against the case where /etc might not be on /, as
36 well as the case where /etc/mtab doesn't exist. (Both are
37 should-never happen scenarios, but you never know...)
39 2001-06-14 Theodore Tso <tytso@valinux.com>
41 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
42 Remove unneeded #pragma argsused, since the arguments are
45 2001-06-13 Theodore Tso <tytso@valinux.com>
47 * ext2_types.h.in: If linux/types.h has been defined, then don't
48 try to redefine the typedefs.
50 * Makefile.in (HFILES): Add ext2_types.h to the list of files
51 which should be installed.
53 * ismounted.c (check_mntent_file): Work around GNU hurd brain
54 damage. Addresses Debian bug #100304.
56 * Makefile.in: Limit some .o files from being included into the
57 library if --disable-debugfs, --disable-swapfs,
58 --disable-imager, or --disable-resizer are used.
60 2001-06-12 Theodore Tso <tytso@valinux.com>
62 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
63 function, and use the ext2fs_badblocks_* functions
66 2001-06-11 Theodore Tso <tytso@valinux.com>
68 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
69 ext2fs_mark_generic_bitmap and
70 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
71 functions. (This saves space and doesn't significantly
72 change the speed of e2fsck on a P-III.)
74 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
75 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
76 include the byte-swapping logic if ENABLE_SWAPFS is turned
77 on or if we're on a big-endian machine.
79 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
80 set EXT2_FLAG_SWAP_BYTES, instead of using
83 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
84 autoconf to determine whether or not return
87 2001-06-10 Theodore Tso <tytso@valinux.com>
89 * Makefile.in: Remove the dependence on the libe2p library.
91 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
92 with direct usage of the ioctl/fchflags so that we don't
93 have to depend on the libe2p library.
95 2001-06-08 Theodore Tso <tytso@valinux.com>
97 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
98 when trying to find a 32-bit wide type.
100 * icount.c (insert_icount_el): Fix the code used to estimate the
101 size of the new icount array to be more intelligent, to
102 avoid reallocating the array too many times. Thanks to
103 Enrique Perez-Terron for pointing this out.
105 2001-06-02 Theodore Tso <tytso@valinux.com>
107 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
108 for a symlink to determine whether it is a fast symlink.
110 2001-06-01 Theodore Tso <tytso@valinux.com>
112 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
113 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
115 2001-05-25 Theodore Tso <tytso@valinux.com>
117 * Release of E2fsprogs 1.20
119 2001-05-25 Theodore Tso <tytso@valinux.com>
121 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
122 some to clean up Andreas's patches. Use strncpy instead
123 of strcpy to save the root's mountpoint. Clean up #ifdef
124 structure. Remove uneeded variable in testing/debug driver.
126 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
128 * ismounted.c: Add check for root device which doesn't depend on
129 /etc/fstab or /proc/mounts to be correct. Don't call
130 endmntent() before we are done with mnt struct.
132 2001-05-23 Theodore Tso <tytso@valinux.com>
134 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
137 2001-05-21 Theodore Tso <tytso@valinux.com>
139 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
140 make room for pre-existing usage of
141 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
142 the same codepoint as EXT2_BTREE_FL.
144 2001-05-20 Theodore Tso <tytso@valinux.com>
146 * ext2fs.h: #include <> instead of "" for ext2fs and et header
147 files, since they will be installed in /usr/include
149 2001-05-14 Theodore Tso <tytso@valinux.com>
151 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
152 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

162 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
163 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
164 Adjust all files in this directroy to include this file.
166 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
169 2001-05-05 Theodore Tso <tytso@valinux.com>
171 * fileio.c (ext2fs_file_read): Factored out common code and
172 cleaned up function. Fixed a bug where if there was an
173 error reading from the disk, the number of bytes read
174 wasn't reliably set. (Fixes Debian bug #79163)
175 (ext2fs_file_write): Factored out common code and made
176 function more efficient; if writing a full block, don't
177 bother to do a read-modify-write cycle.
179 2001-05-04 Theodore Tso <tytso@valinux.com>
181 * dirblock.c (ext2fs_read_dir_block): Check for an directory
182 record length which isn't a multiple four, and treat that
183 as an invalid. Scan the directory and return an error
184 (EXT2_ET_DIR_CORRUPTED) if the directory records are
186 (ext2fs_write_dir_block): If while byte-swapping the
187 directory block, if there's an error, abort and return
188 EXT2_ET_DIR_CORRUPTED.
190 2001-05-02 Theodore Tso <tytso@valinux.com>
192 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
193 image_header field in the ext2_filsys structure
195 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
196 * inode.c (ext2fs_read_inode):
197 * rw_bitmaps.c (read_bitmaps):
198 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
200 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
201 sure the full bitmap is saved.
203 2001-05-01 Theodore Tso <tytso@valinux.com>
205 * e2image.h (struct ext2_image_hdr): Add space for the device name
208 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
209 make sure the rec_len is a multiple of 4, to prevent
210 bus-errors on architectures which care about mis-aligned
213 2001-04-25 Theodore Tso <tytso@valinux.com>
215 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
216 query the device sizes using the BLKGETSIZE ioctl.
218 2001-04-16 Theodore Tso <tytso@valinux.com>
220 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
221 before checking /etc/mtab. The EXT2_MF_READONLY flag is
222 now set from the /etc/mtab options field for all
223 filesystems, not just the root filesystem. Add debugging
224 code to make it easier to test ext2fs_check_if_mounted().
226 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
227 check; return an error if there's an attempt to create a
228 journal less than 1024 filesystem blocks.
230 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
231 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
233 2001-02-20 Theodore Tso <tytso@valinux.com>
235 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
238 * tst_byteswap.c: New function to test the byteswap functions.
239 Add to regression test suite.
241 2001-02-08 Theodore Tso <tytso@valinux.com>
243 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
245 2001-02-07 Theodore Tso <tytso@valinux.com>
247 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
248 of s_first for external devices to always be 1, since
249 jsb->s_first is always relative to the start of the
250 journal superblock. Use htonl(1) when setting s_nr_users.
252 2001-01-17 Theodore Ts'o <tytso@valinux.com>
254 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
255 device number of the filesystem (instead of the journal)
256 was being dropped into s_journal_dev.
258 2001-01-15 Theodore Ts'o <tytso@valinux.com>
260 * initialize.c (ext2fs_initialize): Add support for initializing
261 the ext2 superblock for external journal devices. This
262 basically means we don't bother to allocate any block
265 * openfs.c (ext2fs_open): Only open external journal devices if
266 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
267 ext2fs_open. When opening such devices, don't try to read
268 the block group descriptors, since they're not there.
270 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
272 * mkjournal.c: Export a new function,
273 ext2fs_create_journal_superblock(), which allocates and
274 returns a buffer containing a journal superblock. This is
275 needed by mke2fs to create an external journal. Rewrote
276 ext2fs_add_journal_device() so that it no longer creates
277 the external journal, but rather adds a filesystem to an
278 existing external journal. It handles all of the UUID
281 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
282 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
283 Changed function prototype for ext2fs_add_journal_device().
285 2001-01-14 Theodore Ts'o <tytso@valinux.com>
287 * closefs.c (ext2fs_flush): Don't write out anything beyond the
288 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
291 2001-01-12 Theodore Ts'o <tytso@valinux.com>
293 * imager.c: Fix gcc -Wall complaints and a series of bugs where
294 retval wasn't set correctly. (Thanks to Andreas Dilger
295 for pointing this out.)
297 2001-01-11 <tytso@snap.thunk.org>
299 * flushb.c (ext2fs_sync_device): New function which centralizes
300 all of the places which might try to use the BLKFLSBUF
301 or FDFLUSH ioctls (and usually failing to define them
302 since the system header files don't usually do this for
303 us, and we're trying to avoid usage of kernel include
306 2001-01-10 <tytso@snap.thunk.org>
308 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
309 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
310 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
311 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
312 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
313 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
314 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
315 ext2_ino_t, to protect applications that attempt to
316 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
317 changes ino_t(!?). So we use ext2_ino_t to avoid an
318 unexpected ABI change.
320 2001-01-05 <tytso@snap.thunk.org>
322 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
323 we may overrun allocated memory in case of a corrupted
324 filesystem (or an e2fsck test case :-) when byte-swapping
327 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
329 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
330 complaints including a missing return 0 at the end of
331 ext2fs_add_journal_device.
333 2001-01-03 <tytso@snap.thunk.org>
335 * Makefile.in: Link in libe2p when creating libext2fs as a shared
336 library, since mkjournal.c now references fsetflags().
338 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
339 Dilger's changes (with fixups) to allow on-line creation
342 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
343 EXT2_FLAG_SUPER_ONLY, which the close routines to only
344 update the superblock, and not the group descriptors.
346 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
348 * ismounted.c: add ext2fs_check_mount_point() function, which will
349 optionally return the mount point of a device if mounted
351 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
353 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
354 ext2fs_add_journal_inode()
356 2001-01-01 <tytso@snap.thunk.org>
358 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
359 source (but not binary) compatibility of some users of the
360 ext2 library. They should just simply do a global search
361 and replace of struct ext2fs_sb with struct
362 ext2_super_block, and use their own private copy of
363 ext2_fs.h if they aren't already.
365 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
366 Replace use of ext2fs_sb with ext2_super_block.
368 2000-12-31 <tytso@snap.thunk.org>
370 * ext2fs.h: Cleaned up header file by removing definitions of
371 feature flags that might not have been defined in older
372 ext2 header files. Now that we're using our own
373 include/linux/ext2fs.h header file, this can never happen.
375 * jfs_dat.h: Removed old header file which is no longer needed.
377 2000-12-13 Theodore Ts'o <tytso@valinux.com>
379 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
380 by Andreas Dilger to update the filesystem revision to
383 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
386 2000-12-09 <tytso@snap.thunk.org>
388 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
389 ext2fs_add_journal_device): Add a new argument to the APIs
390 of these function, which is a flags word. This is used to
391 allow the creation of a V1 superblock for those folks who
392 are using ext3 0.3b in production. Note, the user-land
393 interface for getting at this flag won't be documented, as
394 the V1 superblock is deprecated.
396 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
397 which creates a V2 superblock instead of a V1 superblock.
399 2000-11-21 <tytso@snap.thunk.org>
401 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
402 out by Andreas Dilger.
404 2000-11-05 <tytso@snap.thunk.org>
406 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
407 ext2_fs.h, Makefile.in: New file that has routines that
408 save ext2fs metadata to a file.
410 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
412 * e2image.h: New file which defines the file format for the ext2
413 image file. (Saved copy of ext2 metadata to a file as a
414 saving throw against worst-case damage.)
416 2000-11-01 <tytso@snap.thunk.org>
418 * inode.c (ext2fs_flush_icache): Add new function
419 ext2fs_flush_icache() which flushes the internal inode
420 cache. Applications which modify the inode table blocks
421 directly must call this function.
423 2000-10-26 <tytso@snap.thunk.org>
425 * mkjournal.c: Add #include of netinet/in.h, since Solaris
426 requires it for ntohl().
428 * ext2_io.h (io_channel_write_byte): Add new interface to allow
429 callers to write specific byte ranges. This is an
430 optional interface, which not all IO channels may
433 * unix_io.c (unix_write_byte):
434 * test_io.c (test_write_byte): Add implementation of the
437 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
438 function which writes the primary superblock. If the IO
439 channel supports writing raw bytes directly, only fields
440 which were modified are written to the disk. This makes
441 it safe(r) to use utilities like tune2fs on a mounted
444 * freefs.c (ext2fs_free): Free the original superblock if it is
447 * openfs.c (ext2fs_open): Store a copy of the original superblock
450 * ext2fs.h: Add a field to store the original superblock in the
451 ext2 context structure.
453 2000-10-24 <tytso@snap.thunk.org>
455 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
456 don't need to use llseek).
458 2000-10-24 <tytso@valinux.com>
460 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
461 creating an ext3 journal on a filesystem.
463 2000-08-21 <tytso@valinux.com>
465 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
467 2000-08-22 <tytso@valinux.com>
469 * unix_io.c: Make massive changes to support a multiple block
470 writethrough cacheing.
472 * ext2_io.h: Added flags field to the io_channel structure.
474 2000-08-19 <tytso@valinux.com>
476 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
477 provides the function ext2fs_find_block_device(). This
478 function returns the pathname to a block device, given its
481 2000-07-13 <tytso@valinux.com>
483 * Release of E2fsprogs 1.19
485 2000-07-07 Theodore Ts'o <tytso@valinux.com>
487 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
488 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
489 list of filesystem flags supported by the library.
491 2000-07-04 Theodore Ts'o <tytso@valinux.com>
493 * ext2fs.h: Update to include latest journalling additions to the
496 * dll/jump.funcs: Add new jumptable entries for
497 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
498 ext2fs_badblocks_equal.
500 * tst_badblocks.c: Update test program to test
501 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
503 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
504 writes out bad blocks list to a file.
506 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
507 changes the callback function to take two additional
508 arguments; a private blind pointer supplied by the caller,
509 and pointer to a char * containing a pointer to the
512 * badblocks.c (ext2fs_badblocks_equal): Add new function which
513 returns true if two badblocks list are equal.
515 * Makefile.in: Remove explicit link of -lc in the shared library.
516 (It shouldn't be necessary, and is harmful in some cases).
518 2000-06-10 Theodore Ts'o <tytso@valinux.com>
520 * getsize.c (main): Add debugging code under #ifdef DEBUG
522 2000-05-27 Theodore Ts'o <tytso@valinux.com>
524 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
525 earlier, so that if there's an error reading it, we can
526 more cleanly back out of the operation.
528 2000-05-25 <tytso@snap.thunk.org>
530 * getsize.c (ext2fs_get_device_size): Use open64() instead of
531 open() if it exists. Under linux, manually define the
532 ioctl for BLKGETSIZE if it isn't already defined and it's
535 * unix_io.c (unix_open): Use open64() instead of open() if it
538 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
539 available (and prototypes are defined) use it in

549 2000-04-03 Theodore Ts'o <tytso@valinux.com>
551 * block.c: Readibility tweak in conditionals involving
554 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
555 how to define __s64 and __u64. Turn off "compression is
556 experimental" warning if the cpp macro
557 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
559 2000-02-11 <tytso@snap.thunk.org>
561 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.

571 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
572 Change to return the previous state of the bit that is
573 being marked or unmarked. For speed optimization.
575 2000-02-02 Theodore Ts'o <tytso@valinux.com>
577 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
579 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
580 needed any more; we know it will always be i_generation.
581 Add support for swapping the high bits of the uid and gid.
583 1999-11-19 <tytso@valinux.com>
585 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link

599 since ext2fs_badblocks_list_free was moved to freefs.c.
601 * tst_badblocks.c: Use the newer badblocks API names. Add
602 duplicate blocks to the test inputs to test dealing with
603 adding blocks which are already in the badblocks list.
605 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
606 of the list, use a shortcut O(1) operations instead of an
607 O(n) operation. (Idea suggested by David Beattie.)
609 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
610 of badblocks_list_free(), to save a procedure call.
612 1999-10-26 <tytso@valinux.com>
614 * Release of E2fsprogs 1.17
616 1999-10-26 <tytso@valinux.com>

621 1999-10-25 <tytso@valinux.com>
623 * nt_io.c (_OpenNtName): Open the device using
624 FILE_SYNCHRONOUS_IO_NONALERT instead of
625 FILE_SYNCHRONOUS_IO_ALERT
626 (nt_open): At the end of the device open routine, unlock
627 the drive but do not dismount it.
629 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
632 1999-10-22 <tytso@valinux.com>
634 * Release of E2fsprogs 1.16
636 1999-10-22 <tytso@valinux.com>
638 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
640 * link.c (ext2fs_link): This call now uses the low three bits of
641 the flags parameter to pass the directory filetype
642 information; it will set the directory entry FILETYPE
643 information if the filesystem supports it.
645 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
646 option is set, then create the '.' and '..' entries with
647 the filetype set to EXT2_FT_DIR.
649 1999-09-24 <tytso@valinux.com>
651 * nt_io.c: New file which supports I/O under Windows NT.
653 1999-09-07 <tytso@valinux.com>
655 * ext2fs.h: Add new fields for journalling and define new
656 feature bits used by newer filesystems: IMAGIC_INODES,
657 HAS_JOURNAL, RECOVER.
659 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
660 we update the inode block count and size files so that the
661 block count field is updated correctly when we create an
664 1999-07-18 Theodore Ts'o <tytso@valinux.com>
666 * Release of E2fsprogs 1.15
668 1999-06-23 <tytso@valinux.com>
670 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
671 kernels that use i_generation instead of i_version. Patch
672 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
674 1999-06-21 <tytso@valinux.com>
676 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
677 directory entry before calling the callback function.
678 This should prevent some core dumps of insufficiently
679 paranoid callback functions.
681 1999-05-29 <tytso@rsts-11.mit.edu>
683 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
685 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
686 that we don't handle writing yet (we do). Fixed bug where
687 we weren't allocating a big enough buffer for ext2_bmap.
689 1999-05-03 <tytso@rsts-11.mit.edu>
691 * openfs.c (ext2fs_open): Check to make sure that the number of
692 blocks per group is not zero --- if so, it must be a bad
695 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
697 * Release of E2fsprogs 1.14
699 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
701 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
702 the inode number is zero; if it's zero, return
703 EXT2_ET_BAD_INODE_NUM.
705 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
707 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
708 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
711 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
713 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
714 non-Linux case to use EINVAL by default, unless it isn't
715 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
718 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
720 * Release of E2fsprogs 1.13
722 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
724 * Makefile.in: Updated dependencies.
726 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>

729 enough inodes so that we can make a valid filesystem.
731 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
733 * rw_bitmaps.c: Fixed signed/unsigned warnings.
735 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
736 function declaration.
738 * dblist.c (make_dblist): Add safety check in case the dblist
739 pointer passed in is null (in which case, assign it to
740 fs->dblist). Fixed some signed/unsigned warnings.
742 * bmap.c: Make addr_per_block be of type blk_t to avoid
743 signed/unsigned warnings.
745 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
746 function declaration.
748 * get_pathname.c (get_pathname_proc): Use return value from
749 ext2fs_get_mem, instead of checking if &gp->name is

753 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
754 from the function declaration.
756 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
757 return the error directly instead of jumping to the
758 cleanup routine, since we don't need to do any cleanup.
760 * alloc_table.c (ext2fs_allocate_group_table): Make this
761 function take a dgrp_t for its group argument.
763 * ext2fs.h: Make dgrp_t an __u32 type, and make
764 fs->desc_group_count be of type dgrp_t.
766 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
768 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
769 than 10 blocks when we need to expand the size of the
772 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
774 * Release of E2fsprogs 1.12
776 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
778 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
779 appropriate for all of the block group copies, so that
780 it's clear where the beginning of the filesystem is on the
781 disk. (For when the partition table gets scrod.)
783 * ext2fs.h: Change the name of the feature from
784 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
785 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
787 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
789 * inode.c (get_next_blockgroup): Fix bug where if
790 get_next_blockgroup() is called early because of a missing
791 inode table in a block group, the current_inode counter
792 wasn't incremented correctly.
794 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
796 * read_bb.c (ext2fs_read_bb_inode): Make function more robust

799 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
801 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
802 the stride length hits a bad value, we retry the block
803 allocation starting at the beginning of the block group.
805 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
806 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
807 e2_blkcnt_t to avoid collision with LFS API.
809 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
811 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
812 way that avoids overflows on disk sizes greater than 4GB.
814 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
816 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
817 return type for comparison functions for qsort.
819 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
822 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
824 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
827 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
828 evade a potential problem with glibc's header files trying
829 to spike out linux/types.h.
831 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
832 include the old size of the memory, which is needed for
833 some braindamaged memory allocation systems that don't
836 * badblocks.c (ext2fs_badblocks_list_add):
837 bb_inode.c (clear_bad_block_proc):
838 dblist.c (ext2fs_add_dir_block):

848 convention. Fix uninstall rules to take $(DESTDIR) into
851 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
853 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
854 with 32 bit longs, then we need to manually define __s64
855 and __u64, since the current kernel header files don't
856 define these if __STRICT_ANSI__ is defined. This is a
857 problem if we are compiling with full GCC warnings, since
858 we do need 64 bit support.
860 * Makefile.in (OBJS): Remove bmove.o from files to be built,
861 since we're not using ext2fs_move_blocks() and there
862 is some question as to its usefulness in its current
865 * bmap.c (block_bmap): Remove unused function.
867 * bmove.c (process_block): Fix -Wall warning.
869 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
871 * block.c (ext2fs_block_iterate3): Make the ref_offset field
872 contain the offset into the inode.i_blocks array when
873 ref_block is zero. Since we haven't done a formal
874 release of e2fsprogs since block_iterate2 was first
875 introduced, I removed block_iterate2, and renamed
876 block_iterate3 to be block_iterate2.
878 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
879 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
880 use of block_iterate and block_iterate2 to
881 block_iterate2 with the new prototype for the
882 interator function. (using blkcnt_t forr blockcount)
884 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
886 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
887 s_prealloc_blocks, s_prealloc_dir_blocks). Added
888 conditional defines of new features COMPAT_DIR_PREALLOC,
889 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
890 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
891 the library to declare that we support COMPAT_DIR_PREALLOC,
892 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
894 * fileio.c: Rename function ext2fs_file_llseek to be
895 ext2fs_file_lseek, which is more accurate.
897 * block.c: Add new function ext2fs_block_iterate3 which calls
898 the iterator function with the blockcount argument of
899 type blkcnt_t. This version of the function is
900 allowed to handle large files; the other fucntions are
903 * ext2fs.h: Add new type blkcnt_t
905 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
907 * block.c (ext2fs_block_iterate2): Fix bug where the block count
908 field wasn't getting correctly incremented for sparse
909 files when the indirect or doubly-indirect block
910 specified in the inode was zero.
912 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
914 * unlink.c (unlink_proc):
915 * lookup.c (lookup_proc):
916 * link.c (link_proc):
917 * get_pathname.c (get_pathname_proc):
918 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
919 from dirent->name_len, so it can be used for other
922 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
923 and indicate that we have support for this incompatible
926 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
928 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

932 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
933 number of directories when the block group information is
936 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
938 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
939 inode table is missing so that we catch the case where the
940 first block group is missing.
942 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
945 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
947 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
949 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
951 * test_io.c (test_flush): Add a debugging printf when the flush
954 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
955 read in, return right away.
957 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
959 * bitops.h: Don't try to do i386 inline asm functions if the
962 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
963 instead of linux/types.h, and e2_bitops.h instead of
966 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
969 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
971 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
972 so that we don't need to call get_next_blockgroup() the
973 first time around. Saves a bit of time, and prevents us
974 from needing to assign -1 to current_group (which is an
977 * icount.c (insert_icount_el): Cast the estimated number of inodes
978 from a float to an ino_t.
980 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

990 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
991 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is

993 ext2-specific header files are in a flat directory.
995 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
996 all assignments from void * to be compatible with C++.

1017 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1019 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1020 paranoid about validating the directory counts from the
1021 block group information.
1023 * all files: Don't include stdlib.h anymore; include it in
1024 ext2_fs.h, since that file requires stdlib.h
1026 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1028 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1029 bitmap is loaded, and return an error if it is not.
1030 (expand_dir_proc): Only use ext2fs_write_dir_block when
1031 writing a directory block, not when writing out a fresh
1034 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1036 * Makefile.in, tst_getsize.c: Added new file which is used to test

1082 * fileio.c: New file which implements simple file reading and
1085 * alloc.c (ext2fs_alloc_block): New function which allocates a
1086 block, zeros it, and updates the filesystem accounting
1087 records appropriately.

1091 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
1092 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
1093 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
1095 * Change various library files to use these functions instead of
1096 EINVAL, ENOENT, etc.
1098 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1100 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
1101 need to declare llseek().
1103 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1105 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1107 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
1109 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1143 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1145 * io.h: Change the prototype of ext2fs_llseek() to use int's
1146 instead of unsigned int's.
1148 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1149 to make life easer for GNU Libc 2.
1151 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1152 filesystem has its bitmaps stored as 32-bit words with bit
1153 0 as the LSB of each word. Thus a bitmap with only bit 0
1154 set would be, as a string of bytes, 00 00 00 01 00 ... To
1155 cope with this, we byte-reverse each word of a bitmap if
1156 we have a big-endian filesystem, that is, if we are *not*
1157 byte-swapping other word-sized numbers.
1159 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1217 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
1218 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c

1223 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
1224 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
1226 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1228 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1229 is zero, then return EXT2_IO_LLSEEK_FAILED.
1231 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1233 * Release of E2fsprogs 1.11
1235 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1237 * dblist.c (ext2fs_dblist_count): Added new function which returns
1238 the number of directory blocks in dblist.
1240 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1242 * unix_io.c (unix_flush): Make the io_channel flush function do a
1243 fsync to flush the kernel buffers to disk.
1245 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1247 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1248 current inode number wasn't being set by the
1249 goto_blockgroup function.
1251 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1253 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1254 of blocks which need to be moved, and moves those blocks
1255 to another location in the filesystem.
1257 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1258 bitmap, make sure all of the new parts of the bitmap are
1261 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1263 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1264 wasn't being returned to the caller.
1266 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1267 ext2fs_allocate_group_table() which sets the group tables
1268 for a particular block group. The relevant code was
1269 factored out of ext2fs_allocate_tables().
1271 * dblist.c (make_dblist): Adjust the initial size of the directory
1272 block list to be a bit more realistic (ten plus twice the
1273 number of directories in the filesystem).
1275 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1277 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1278 ext2fs_badblocks_list_test would test the list (and exceed
1279 array boundaries) if there were no bad blocks on the bad
1280 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1282 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1284 * Release of E2fsprogs version 1.10
1286 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1288 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1289 inode and block bitmaps based on the RAID 0 stride
1290 parameter (which is passed by mke2fs).
1292 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1293 mke2fs to communicate the stride length to
1294 ext2fs_allocate_tables()
1296 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1298 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1299 systems. (We can't assume that the new filesystem types
1302 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1304 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1305 allocate the inode and block bitmaps inside block group at
1308 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1310 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1311 filesystem has no free blocks, ext2fs_new_block would loop
1314 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1316 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1317 free if refcount goes to zero.
1319 * inode.c (create_icache): Initialize refcount to 1.
1321 * ext2fsP.h: Added refcount to ext2_inode_cache
1323 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
1326 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1327 badblocks structure.
1329 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1331 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
1333 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1335 (unix_close, test_close): Decrement the refcount and only
1336 close the io_channel if the refcount goes to 0.
1338 * io.h: Add refcount to the io_channel structure. Add new macro
1339 interface io_channel_bumpcount() to bump the refcount.
1341 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1343 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1344 cache in the filesystem handle, instead of the inode cache
1345 in a static variable.
1347 * freefs.c: Added static function to free the inode cache (called by
1350 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1352 * ext2fs.h: Added pointer to the inode_cache structure.
1354 * block.c (block_iterate_ind, block_iterate_dind,
1355 block_iterate_tind): If there are holes in the indirect,
1356 doubly indirect, or triply indirect blocks, increment the
1357 block count field automatically.
1359 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1361 * Release of E2fsprogs version 1.09
1363 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1365 * version.c (ext2fs_parse_version_string): Check the passed in
1366 version string (instead of the hard-coded one).
1368 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1369 greater filesystem size, clamp it to prevent allocating a
1370 block or inode bitmap beyond the filesystem.
1372 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1373 overhead calculation was accidentally removed.
1375 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1377 * Release of E2fsprogs version 1.08
1379 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1381 * dblist.c (ext2fs_set_dir_block): New function which sets the
1382 block of a dblist entry, given the directory inode and
1385 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1387 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1388 inode bitmaps at staggered locations across the block
1389 groups, to avoid concentrating the bitmaps on a small
1390 number of disks when using striped RAID arrays.
1392 * initialize.c (ext2fs_initialize): By default, choose the maximum
1393 possible number of blocks per group (based on the size of
1394 the bitmaps in the blocksize).
1396 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1398 * initialize.c (ext2fs_initialize): Add support for
1399 EXT2_COMPAT_SPARSE_SUPER feature.
1401 * closefs.c (ext2fs_bg_has_super): New function to determine
1402 whether or a particular block group should have a
1403 superblock and block group descriptor. Used for the
1404 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1405 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1406 or not the superblock should be written out for the block
1409 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1410 for sparse duplicate superblocks.
1412 * version.c (ext2fs_get_library_version): New function which
1413 returns the library version.
1415 * version.c (ext2fs_parse_version_string): New function which
1416 parses a version string and returns a version number,
1417 so application programs can compare version numbers as
1420 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1422 * icount.c (ext2fs_create_icount): Change function so that it also
1423 takes a new argument which contains a "hint" icount
1424 structure. This "hint" icount allows the create function
1425 to set up the sorted list in advance. This reduces
1426 significantly the amount of data moving needed to insert
1427 these inodes into the list later.
1429 * icount.c (ext2fs_icount_validate): New function which validates
1430 that the icount structure's rep invariant.
1432 * icount.c (get_icount_el): Completely revamped implementation
1433 to subsume put_icount_el(). Put_icount_el() used to
1434 use an O(N) implementation to insert in the middle
1435 of the icount list. It now uses a O(ln N) to search
1436 for where the icount should be inserted, and then uses
1437 a memcpy to move the list down (instead of a for loop).
1439 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1440 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1441 to see if the inode is within bounds; if it isn't, return
1444 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1445 when a bad inode number is passed to test_generic_bitmap
1446 to be EXT2FS_TEST_ERROR instead of the wrong
1447 EXT2FS_UNMARK_ERROR.
1449 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1451 * Release of E2fsprogs version 1.07
1453 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1455 * Makefile.in (ELF_VERSION): Change version to be 2.2
1457 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1459 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1460 ext2fs_fast_test_block_bitmap_range().
1462 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1463 ext2fs_test_block_bitmap_range: New inline functions which
1464 test to see whether a contiguous range of blocks is
1467 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1469 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1470 use ext2fs_badblocks_* instead of badblocks_*
1472 * bb_compat.c: New file which translates between old badblocks_*()
1473 names to ext2fs_badblocks_*()
1475 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1476 link.c (since e2fsck doesn't use ext2fs_unlink()).
1478 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1479 bitmap resizing routine moved from bitmaps.c, since e2fsck
1480 doesn't need to use this function.
1482 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1483 since e2fsck only needs ext2fs_lookup.
1485 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1487 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1488 already set; this is needed so that programs like dump
1489 which use the inode scan functions will deal with
1490 filesystems that have bad blocks in the inode table.
1492 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1494 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1495 Moved to ext2fsP.h, since it doesn't need to be part of
1496 the public interface.
1498 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1500 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1502 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1503 directory block list abstraction. (Code moved from
1506 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1507 to inode.c (since no one else should be peeking inside it!)
1509 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1511 * openfs.c (ext2fs_open): Check the feature set in the ext2
1512 superblock, and refuse to open filesystems if they contain
1513 incompatible features. (Can be overriden with the
1516 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1518 * block.c (ext2fs_block_iterate2): Added new function
1519 ext2fs_block_iterate2 which changes the function
1520 signature of the callback function to include the
1521 referencing block and offset.
1523 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1524 ext2fs_inode_scan_goto_blockgroup which allows an
1525 application to jump to a particular block group while
1526 doing an inode scan.
1528 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1530 * dirblock.c: Include string.h, since we use memcpy().
1532 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1534 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1535 a long not an int; this doesn't matter on i386 machines,
1536 but it does on Alpha's.
1538 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1540 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1541 table pointer is NULL, then return an error indicating
1542 that the inode table is missing.
1543 (get_next_blockgroup, get_next_blocks,
1544 ext2fs_get_next_inode): Don't treat a missing inode table
1545 as permanent error. Return MISSING_INODE_TABLE, but as an
1546 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1548 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1549 ext2fs_write_inode_bitmap): If the inode or block bitmap
1550 block is zero, then don't write out the inode or block
1551 bitmap. The idea here is to avoid stomping on the
1553 (read_bitmaps): If the inode or block bitmap block is
1554 zero, then fill in that portion of the inode or block
1555 bitmap with all zeros.
1557 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1558 blocks in inode table when the inode table size is
1559 non-standard (and can therefore span blocks).
1561 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1563 * alloc.c (ext2fs_new_block): Fix fencepost error in
1564 ext2fs_new_block; make sure we don't try to allocate the
1565 first block beyond the end of the filesystem.
1567 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1569 * inode.c (check_for_inode_bad_blocks): New function called by
1570 get_next_blocks() to avoid reading in bad blocks marked in
1571 fs->badblocks. Inodes located in bad blocks are returned
1572 by ext2fs_get_next_inode() returns the error code
1573 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1575 * alloc_tables.c (ext2fs_allocate_tables): New function which
1576 performs the part of mke2fs's job of allocating the
1579 * test_io.c (test_close): IO manager which is used for testing
1582 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1584 * inode.c (ext2fs_get_next_inode): Separate out the function of
1585 setting up for a new block group to get_next_blockgroup().
1586 Separate out the function of reading in blocks of the
1587 inode table to get_next_blocks().
1589 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1591 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1592 blocks to the badblock list in sorted order. This allows
1593 badblocks_list_test to be coded using a binary search for
1596 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1598 * Release of E2fsprogs version 1.06

1603 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1606 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1607 set, then only write out the master superblock.
1609 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1611 * block.c (ext2fs_block_iterate): Fixed bug which caused
1612 block_iterate to fail to handle HURD created filesystems;
1613 it tested the inode translator field before the inode was

1647 * namei.c (ext2fs_follow_link): New function.
1648 (ext2fs_namei): Extended to have support for chasing
1649 symbolic links. ext2fs_namei() still returns an inode
1650 which is a symbolic link. Symbolic links are only chased
1651 while resolving the containing directory. To chase
1652 symbolic links of the final result, use
1653 ext2fs_follow_link().
1655 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1657 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.

1664 * initialize.c (ext2fs_initialize): On systems where the byte
1665 order is not i386 compatible, set the swap_byte flag.
1667 * inode.c (inocpy_with_swap): Check to see if inode contains a
1668 fast symlink before swapping the inode block fields. This
1669 required adding a new argument to inocpy_with_swap to
1670 determine whether the mode field is in host order or not.
1672 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1674 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1675 the sparc, if EXT2_STD_BITOPS set, use the standard
1676 i386-compatible bitmask operations, instead on the
1677 non-standard native bitmask operators.

1681 * block.c (ext2fs_block_iterate): Cause block iterator to return
1682 the HURD translator block (along with everything else).

1684 iterator, then don't return any meta data blocks
1685 (including the HURD translator).
1687 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1689 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1691 * uuid.c: New file, containing UUID utility functions.
1693 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1699 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1701 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1703 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1704 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1705 that's a basic value that must be correct for the rest of
1706 the library to work.
1708 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1711 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1722 Change the m68k bit numbering for bitmasks to match with
1723 the bit numbering used by all other ext2 implementations.
1725 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1727 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

1760 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1761 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1762 to avoid conflicts with with kernel include files. Also
1763 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1766 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1768 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c

1788 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1791 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1793 * unix_io.c (unix_open): Add a double check; if the passed in name
1794 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1796 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1798 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

1806 partition size from a BSD disk label.
1808 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1810 * getsize.c (ext2fs_get_device_size): New function that determins

1820 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1821 Move these functions to freefs.c.
1823 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1824 descriptors shadow memory to keep purify quiet. (This
1825 also has the nice benefit that the unused portion of the
1826 shadow descriptors are zeroed out.)
1828 * dirblock.c (ext2fs_write_dir_block): We need to use
1829 dirent->rec_len *before* it's byteswapped to find the
1830 location of the next directory structure!
1832 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1833 cause ext2fs_new_inode to loop infinitely if we're trying
1834 to allocate an inode in group #0 and there are no free
1835 inodes at all in the system.
1837 * closefs.c: #include <errno.h> if it exists.
1839 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

1858 file containing functions for reading and writing
1859 directory blocks (byte swapping if necesssary)
1861 * block.c (block_iterate_ind, block_iterate_dind,
1862 block_iterate_tind): Byte swap the block addresses if

1868 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1870 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1871 the superblock and group descriptors before writing it out.
1873 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1874 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1875 and group descriptors.
1877 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1878 to desp ext2 filesystem structures.
1880 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1881 supplied by Pete A. Zaitcev so that the C language
1882 versions of these functions are more portable. They will
1883 now work on both little and big endian systems, and the
1884 assumption that 32-bit integers are used is gone.
1886 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1887 doing byte swapping.
1889 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1890 byte swapping should take place.
1892 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

1903 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1904 if the magic number is correct, it will be allocated.
1906 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1908 * block.c (block_iterate_ind, block_iterate_dind,
1909 block_iterate_tind): Don't recompute block_nr each loop;
1910 just increment it! Factor check of BLOCK_FLAG_APPEND out
1911 of the loop. Factor mask of BLOCK_CHANGED into changed
1912 variable out of the loop. (block_iterate_ind, in
1913 particular, gets called a lot, so every little
1914 optimization helps.)
1916 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1918 * block.c (block_iterate_ind, block_iterate_dind,

1925 ext2fs_fast_test_inode_bitmap): Add fast version of these
1926 functions, which don't do range checking.

1930 ext2fs_get_inode_bitmap_end): Add new accessor functions
1931 which return the start and end points of the bitmaps.
1933 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1935 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1936 instead of llseek. The errno if the offset is too large
1937 and lseek is not supported should be EINVAL, not -EINVAL.
1939 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1941 * Makefile.in: Added support for ELF shared libraries.
1942 Fixed typos in the compilation rules.
1943 (distclean): Added Makefile.
1945 * llseek.c (llseek): New function, if llseek() does not exist in the

1957 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1958 the S_*, which are normally defined in <sys/stat.h>. This
1959 allows us to compile e2fsprogs on a non-Linux system,
1960 which may have a different value for S_IFDIR.
1962 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1964 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1965 this is a user-mode application!
1967 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1969 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1970 __linux__ so that non-linux systems won't see it.
1972 * alloc.c: Include <errno.h> if possible.
1973 * badblocks.c: Ditto.
1974 * bb_inode.c: Ditto.
1977 * expanddir.c: Ditto.

1994 * initialize.c (ext2fs_initialize): Don't allow more than one
1995 bitmaps's worth of inodes in a group.
1997 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1999 * llseek.c (ext2_llseek): Added error checking to the llseek()
2000 compat code to protect against overflow. This only
2001 applies to 1.0 and early 1.1 kernels, which don't support
2002 the llseek() system call.
2004 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2006 * unix_io.c (unix_open): Initialize the read_error and write_error
2007 io_channel pointers to be null.
2009 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2010 found, clear it but don't try to update the filesystem
2011 accounting information, since that's hopeless anyway.
2013 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2014 bloblock_iterate_tind): Check to see if the indirect blocks are
2015 valid before trying to read them.

2021 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2022 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2023 illegal block or inode number is passed in, return instead
2024 of trying to test, set, or clear the bit.
2026 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2028 * Makefile: Added a dummy install target in case shared libraries

2083 * check_desc.c (ext2fs_check_desc):
2084 * closefs.c (ext2fs_close, ext2fs_flush):
2085 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2090 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2091 openfs.c into its own file.
2093 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2094 structure magic numbers.
2096 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2097 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2098 someone uses the -b option to specify the use of the backup
2099 superblock --- this usually means that the main superblock is
2103 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2104 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2105 revision level to the superblock.

2114 * initialize.c: Completely revamped the inode and block bitmap
2115 structures, so that they can be better chance of being extensible
2116 in a shared library. They are now their own type, instead of
2117 being a char *. Also, the function signatures of
2118 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2119 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2120 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2121 changed to eliminate the ext2_filsys argument, since it is no
2124 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2126 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2127 system call if available.
2129 * llseek.c: new file. This is the stub calling the llseek system
2130 call which allows supports for 2GB+ file systems.
2132 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2133 the creator operating system.
2135 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2137 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2138 the group descriptor statistics in addition to everything else.
2139 This relieves mke2fs of the responsibility of doing it.
2141 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2142 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2143 not the generic C function equivalents should be included or not.
2145 * openfs.c (ext2fs_open): If a superblock is specified, then use
2146 the backup group descriptors that go along with this superblock,
2147 instead of using the primary group descriptors. This allows
2148 e2fsck to recover filesystems where the primary group descriptors
