1 2002-02-12 Theodore Tso <tytso@valinux.com>
3 * Makefile.in (tst_badblocks): Add some extra .o files when
4 linking the debugging program tst_badblocks which are
5 needed if we aren't compiling with inline functions enable.
7 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
8 define away __inline__ since it may not be supported.
10 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
11 stripped down jbd_debug that doesn't use variadic
12 arguments. This will cause warnings under AIX, but things
15 2002-02-03 Theodore Tso <tytso@thunk.org>
17 * Release of E2fsprogs 1.26
19 2002-02-03 Theodore Tso <tytso@valinux.com>
21 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
22 so that the number of directories in use is adjusted
25 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
26 which optionally will modify the number of directories
29 2002-01-03 Theodore Tso <tytso@mit.edu>
31 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
32 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
33 which will return deleted directory entries.
34 ext2fs_dir_iterate2 takes a new callback function which
35 is identical with the one used by
36 ext2fs_dblist_dir_iterate(). If the directory entry is
37 deleted, the callback function will be called with the
38 entry paraemter set to DIRENT_DELETED_FILE.
40 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
41 ext2fs_block_alloc_stats): New functions which update
42 block/inode allocation statistics in the bitmaps, block
43 group descriptors, and superblock.
45 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
46 expanddir.c (expand_dir_proc), bb_inode.c
47 (clear_bad_block_proc, set_bad_block_proc,
48 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
49 Update to use new block/inode allocation statistics.
51 2001-12-24 Theodore Tso <tytso@mit.edu>
53 * ismounted.c (is_swap_device): New function used by
54 ext2fs_check_if_mounted and ext2fs_check_mount_point which
55 determines whether or not the specified device is a swap
56 device by using /proc/swaps. More bulletproofing for
57 idiotic/careless system administrators!
59 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
60 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
61 field to struct_ext2_filsys, umask. This field is
62 initialize to 022, and affects ext2fs_mkdir in the obvious
63 way. (In the future umask should also affect new file
64 creation routines, but the fileio functions don't
65 currently support this yes.)
67 * ismounted.c (check_mntent_file): Stat all of the entries in
68 /etc/mtab and/or /proc/mounts in order to catch dim-witted
69 system administrators who might have created alias
72 2001-12-23 Theodore Tso <tytso@mit.edu>
74 * Makefile.in, jfs_user.h: Move linux/jbd.h to
75 ext2fs/kernel-jbd.h, to avoid using the system header
76 file version of hbd.h when using diet glibc (since it
77 forcibly adds /usr/include to the beginning of the
80 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
81 include/linux directory.
83 2001-12-16 Theodore Tso <tytso@mit.edu>
85 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
86 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
87 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
89 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
92 2001-12-03 Theodore Tso <tytso@mit.edu>
94 * unix_io.c (unix_open): Make sure the ulimit workaround works
95 regardless of the version of glibc which is used to
98 2001-11-26 Theodore Tso <tytso@mit.edu>
100 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
101 trying to unset the filesize limit if at all possible,
102 if a block device is getting opened. (The filesize limit
103 shouldn't be applied against writes to a block device, but
104 starting in 2.4.10, the kernel is doing this.)
106 2001-11-05 Theodore Tso <tytso@mit.edu>
108 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
109 file on adding a journal to an already-mounted filesystem,
110 try to clear the ext2 file attributes on an already
111 existing .journal file so that we don't fail if on a
112 partially added journal to the filesystem.
114 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
115 which signals that a particular inode should not have the
116 last bits of data (the "tail") be merged with another
117 file. This is necessary to keep LILO happy.
119 2001-09-20 Theodore Tso <tytso@thunk.org>
121 * Release of E2fsprogs 1.25
123 2001-09-16 Theodore Tso <tytso@mit.edu>
125 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
126 which was breaking the build on the Hurd. (Addresses
129 2001-09-13 Theodore Ts'o <tytso@mit.edu>
131 * ismounted.c (check_mntent_file): We now validate the entry in
132 /etc/mtab to make sure the filesystem is really mounted,
133 since some broken distributions (read: Slackware) have
134 buggy boot scripts that don't initialize /etc/mtab before
135 checking non-root filesystems. (Slackware also doesn't
136 check the root filesystem separately, and reboot if the
137 root filesystem had changes applied to it, which is
138 dangerous and broken.)
140 2001-09-02 Theodore Tso <tytso@thunk.org>
142 * Release of E2fsprogs 1.24a
144 2001-08-30 Theodore Tso <tytso@thunk.org>
146 * Release of E2fsprogs 1.24
148 2001-08-30 Theodore Tso <tytso@valinux.com>
150 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
151 changes, since the ioctl number has been reused by another
154 2001-08-15 Theodore Tso <tytso@valinux.com>
156 * Release of E2fsprogs 1.23
158 2001-08-05 Theodore Tso <tytso@valinux.com>
160 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
161 version of the bitmap test routines to speed up these
162 routines. (At some point I may want to make these
163 routines use the find_first_bit functions, but that will
164 add a lot of complexity since it means that these
165 functions will have to break the bitmap abstraction
166 boundary. It's not clear it's worth it.)
168 * mkjournal.c (mkjournal_proc): Remember the last block allocated
169 to speed up ext2fs_new_block().
171 2001-07-29 Theodore Tso <tytso@valinux.com>
173 * finddev.c (scan_dir): Fix memory leak; we weren't calling
174 closedir() when exiting the function in all cases.
176 2001-07-27 Theodore Tso <tytso@valinux.com>
178 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
179 block usable in the journal for external journals to be 2
180 or 3, depending on the blocksize, so that the existing
181 kernel code does the right thing.
183 * getsize.c (ext2fs_get_device_size): Add support for the
184 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
185 from Ben LaHaise, but it's likely this interface won't
188 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
189 when writing the journal superblock, too. (Oops! Needed
190 to make 1k filesystems with external journal to work.)
192 2001-07-26 Theodore Tso <tytso@valinux.com>
194 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
195 to find the journal superblock if the blocksize is 1024.
197 2001-07-21 Theodore Tso <tytso@valinux.com>
199 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
201 2001-07-20 Theodore Tso <tytso@valinux.com>
203 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
204 attribute block, set the filesystem changed bit.
206 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
207 Comment out these functions since we're not using them.
209 2001-07-10 Theodore Tso <tytso@valinux.com>
211 * closefs.c (write_primary_superblock): After writing changes to
212 the primary superblock, update the original superblock
213 copy so we don't have to re-write those changes in the
215 (ext2fs_flush): Clear the superblock dirty flag after
216 we've flushed out changes to disk.
218 2001-07-07 Theodore Tso <tytso@valinux.com>
220 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
221 to avoid register conflicts when compiling in PIC mode.
223 2001-07-04 Theodore Tso <tytso@valinux.com>
225 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
226 Add new functions (C and in i386 assembler) which quickly
227 find bits set in a bitmask.
229 2001-06-23 Theodore Tso <tytso@valinux.com>
231 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
232 ext2_ext_attr.h and ext_attr.c for extended attributes
235 * Release of E2fsprogs 1.22
237 2001-06-22 Theodore Tso <tytso@valinux.com>
239 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
240 descriptor so that adding a journal to a mounted
241 filesystem doesn't die. (Fixes a bug accidentally
242 introduced in e2fsprogs 1.21.)
244 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
245 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
246 fchflags without defining UF_NODUMP. (Addresses Debian
249 * flushb.c: Use platform independent method of defining the
250 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
251 since on newer glibc's BLKFLSBUF is defined there.
253 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
254 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
255 to support byte swapping even if we don't support the
256 conversion functions. (Fixes Debian bug #101686).
258 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
259 since the byte-swapping code all assumes the
260 ext2_dir_entry structure. (It's a question of whether or
261 not name_len should be byte-swapped or not, and whether
262 it's a 16 bit or 8 bit field.)
264 2001-06-15 Theodore Tso <tytso@valinux.com>
266 * Release of E2fsprogs 1.21
268 2001-06-15 Theodore Tso <tytso@valinux.com>
270 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
271 file which is generated and is therefore found in the
272 build directory, not source directory.
274 * ismounted.c (check_mntent_file): Use a test file in / to check
275 to see if the root filesystem is mounted read-only. This
276 protects against the case where /etc might not be on /, as
277 well as the case where /etc/mtab doesn't exist. (Both are
278 should-never happen scenarios, but you never know...)
280 2001-06-14 Theodore Tso <tytso@valinux.com>
282 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
283 Remove unneeded #pragma argsused, since the arguments are
286 2001-06-13 Theodore Tso <tytso@valinux.com>
288 * ext2_types.h.in: If linux/types.h has been defined, then don't
289 try to redefine the typedefs.
291 * Makefile.in (HFILES): Add ext2_types.h to the list of files
292 which should be installed.
294 * ismounted.c (check_mntent_file): Work around GNU hurd brain
295 damage. Addresses Debian bug #100304.
297 * Makefile.in: Limit some .o files from being included into the
298 library if --disable-debugfs, --disable-swapfs,
299 --disable-imager, or --disable-resizer are used.
301 2001-06-12 Theodore Tso <tytso@valinux.com>
303 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
304 function, and use the ext2fs_badblocks_* functions
307 2001-06-11 Theodore Tso <tytso@valinux.com>
309 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
310 ext2fs_mark_generic_bitmap and
311 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
312 functions. (This saves space and doesn't significantly
313 change the speed of e2fsck on a P-III.)
315 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
316 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
317 include the byte-swapping logic if ENABLE_SWAPFS is turned
318 on or if we're on a big-endian machine.
320 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
321 set EXT2_FLAG_SWAP_BYTES, instead of using
324 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
325 autoconf to determine whether or not return
326 EXT2_FLAG_SWAP_BYTES.
328 2001-06-10 Theodore Tso <tytso@valinux.com>
330 * Makefile.in: Remove the dependence on the libe2p library.
332 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
333 with direct usage of the ioctl/fchflags so that we don't
334 have to depend on the libe2p library.
336 2001-06-08 Theodore Tso <tytso@valinux.com>
338 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
339 when trying to find a 32-bit wide type.
341 * icount.c (insert_icount_el): Fix the code used to estimate the
342 size of the new icount array to be more intelligent, to
343 avoid reallocating the array too many times. Thanks to
344 Enrique Perez-Terron for pointing this out.
346 2001-06-02 Theodore Tso <tytso@valinux.com>
348 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
349 for a symlink to determine whether it is a fast symlink.
351 2001-06-01 Theodore Tso <tytso@valinux.com>
353 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
354 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
356 2001-05-25 Theodore Tso <tytso@valinux.com>
358 * Release of E2fsprogs 1.20
360 2001-05-25 Theodore Tso <tytso@valinux.com>
362 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
363 some to clean up Andreas's patches. Use strncpy instead
364 of strcpy to save the root's mountpoint. Clean up #ifdef
365 structure. Remove uneeded variable in testing/debug driver.
367 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
369 * ismounted.c: Add check for root device which doesn't depend on
370 /etc/fstab or /proc/mounts to be correct. Don't call
371 endmntent() before we are done with mnt struct.
373 2001-05-23 Theodore Tso <tytso@valinux.com>
375 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
378 2001-05-21 Theodore Tso <tytso@valinux.com>
380 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
381 make room for pre-existing usage of
382 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
383 the same codepoint as EXT2_BTREE_FL.
385 2001-05-20 Theodore Tso <tytso@valinux.com>
387 * ext2fs.h: #include <> instead of "" for ext2fs and et header
388 files, since they will be installed in /usr/include
390 2001-05-14 Theodore Tso <tytso@valinux.com>
392 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
393 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

403 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
404 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
405 Adjust all files in this directroy to include this file.
407 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
410 2001-05-05 Theodore Tso <tytso@valinux.com>
412 * fileio.c (ext2fs_file_read): Factored out common code and
413 cleaned up function. Fixed a bug where if there was an
414 error reading from the disk, the number of bytes read
415 wasn't reliably set. (Fixes Debian bug #79163)
416 (ext2fs_file_write): Factored out common code and made
417 function more efficient; if writing a full block, don't
418 bother to do a read-modify-write cycle.
420 2001-05-04 Theodore Tso <tytso@valinux.com>
422 * dirblock.c (ext2fs_read_dir_block): Check for an directory
423 record length which isn't a multiple four, and treat that
424 as an invalid. Scan the directory and return an error
425 (EXT2_ET_DIR_CORRUPTED) if the directory records are
427 (ext2fs_write_dir_block): If while byte-swapping the
428 directory block, if there's an error, abort and return
429 EXT2_ET_DIR_CORRUPTED.
431 2001-05-02 Theodore Tso <tytso@valinux.com>
433 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
434 image_header field in the ext2_filsys structure
436 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
437 * inode.c (ext2fs_read_inode):
438 * rw_bitmaps.c (read_bitmaps):
439 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
441 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
442 sure the full bitmap is saved.
444 2001-05-01 Theodore Tso <tytso@valinux.com>
446 * e2image.h (struct ext2_image_hdr): Add space for the device name
449 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
450 make sure the rec_len is a multiple of 4, to prevent
451 bus-errors on architectures which care about mis-aligned
454 2001-04-25 Theodore Tso <tytso@valinux.com>
456 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
457 query the device sizes using the BLKGETSIZE ioctl.
459 2001-04-16 Theodore Tso <tytso@valinux.com>
461 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
462 before checking /etc/mtab. The EXT2_MF_READONLY flag is
463 now set from the /etc/mtab options field for all
464 filesystems, not just the root filesystem. Add debugging
465 code to make it easier to test ext2fs_check_if_mounted().
467 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
468 check; return an error if there's an attempt to create a
469 journal less than 1024 filesystem blocks.
471 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
472 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
474 2001-02-20 Theodore Tso <tytso@valinux.com>
476 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
479 * tst_byteswap.c: New function to test the byteswap functions.
480 Add to regression test suite.
482 2001-02-08 Theodore Tso <tytso@valinux.com>
484 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
486 2001-02-07 Theodore Tso <tytso@valinux.com>
488 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
489 of s_first for external devices to always be 1, since
490 jsb->s_first is always relative to the start of the
491 journal superblock. Use htonl(1) when setting s_nr_users.
493 2001-01-17 Theodore Ts'o <tytso@valinux.com>
495 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
496 device number of the filesystem (instead of the journal)
497 was being dropped into s_journal_dev.
499 2001-01-15 Theodore Ts'o <tytso@valinux.com>
501 * initialize.c (ext2fs_initialize): Add support for initializing
502 the ext2 superblock for external journal devices. This
503 basically means we don't bother to allocate any block
506 * openfs.c (ext2fs_open): Only open external journal devices if
507 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
508 ext2fs_open. When opening such devices, don't try to read
509 the block group descriptors, since they're not there.
511 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
513 * mkjournal.c: Export a new function,
514 ext2fs_create_journal_superblock(), which allocates and
515 returns a buffer containing a journal superblock. This is
516 needed by mke2fs to create an external journal. Rewrote
517 ext2fs_add_journal_device() so that it no longer creates
518 the external journal, but rather adds a filesystem to an
519 existing external journal. It handles all of the UUID
522 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
523 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
524 Changed function prototype for ext2fs_add_journal_device().
526 2001-01-14 Theodore Ts'o <tytso@valinux.com>
528 * closefs.c (ext2fs_flush): Don't write out anything beyond the
529 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
532 2001-01-12 Theodore Ts'o <tytso@valinux.com>
534 * imager.c: Fix gcc -Wall complaints and a series of bugs where
535 retval wasn't set correctly. (Thanks to Andreas Dilger
536 for pointing this out.)
538 2001-01-11 <tytso@snap.thunk.org>
540 * flushb.c (ext2fs_sync_device): New function which centralizes
541 all of the places which might try to use the BLKFLSBUF
542 or FDFLUSH ioctls (and usually failing to define them
543 since the system header files don't usually do this for
544 us, and we're trying to avoid usage of kernel include
547 2001-01-10 <tytso@snap.thunk.org>
549 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
550 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
551 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
552 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
553 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
554 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
555 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
556 ext2_ino_t, to protect applications that attempt to
557 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
558 changes ino_t(!?). So we use ext2_ino_t to avoid an
559 unexpected ABI change.
561 2001-01-05 <tytso@snap.thunk.org>
563 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
564 we may overrun allocated memory in case of a corrupted
565 filesystem (or an e2fsck test case :-) when byte-swapping
568 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
570 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
571 complaints including a missing return 0 at the end of
572 ext2fs_add_journal_device.
574 2001-01-03 <tytso@snap.thunk.org>
576 * Makefile.in: Link in libe2p when creating libext2fs as a shared
577 library, since mkjournal.c now references fsetflags().
579 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
580 Dilger's changes (with fixups) to allow on-line creation
583 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
584 EXT2_FLAG_SUPER_ONLY, which the close routines to only
585 update the superblock, and not the group descriptors.
587 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
589 * ismounted.c: add ext2fs_check_mount_point() function, which will
590 optionally return the mount point of a device if mounted
592 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
594 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
595 ext2fs_add_journal_inode()
597 2001-01-01 <tytso@snap.thunk.org>
599 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
600 source (but not binary) compatibility of some users of the
601 ext2 library. They should just simply do a global search
602 and replace of struct ext2fs_sb with struct
603 ext2_super_block, and use their own private copy of
604 ext2_fs.h if they aren't already.
606 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
607 Replace use of ext2fs_sb with ext2_super_block.
609 2000-12-31 <tytso@snap.thunk.org>
611 * ext2fs.h: Cleaned up header file by removing definitions of
612 feature flags that might not have been defined in older
613 ext2 header files. Now that we're using our own
614 include/linux/ext2fs.h header file, this can never happen.
616 * jfs_dat.h: Removed old header file which is no longer needed.
618 2000-12-13 Theodore Ts'o <tytso@valinux.com>
620 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
621 by Andreas Dilger to update the filesystem revision to
624 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
627 2000-12-09 <tytso@snap.thunk.org>
629 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
630 ext2fs_add_journal_device): Add a new argument to the APIs
631 of these function, which is a flags word. This is used to
632 allow the creation of a V1 superblock for those folks who
633 are using ext3 0.3b in production. Note, the user-land
634 interface for getting at this flag won't be documented, as
635 the V1 superblock is deprecated.
637 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
638 which creates a V2 superblock instead of a V1 superblock.
640 2000-11-21 <tytso@snap.thunk.org>
642 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
643 out by Andreas Dilger.
645 2000-11-05 <tytso@snap.thunk.org>
647 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
648 ext2_fs.h, Makefile.in: New file that has routines that
649 save ext2fs metadata to a file.
651 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
653 * e2image.h: New file which defines the file format for the ext2
654 image file. (Saved copy of ext2 metadata to a file as a
655 saving throw against worst-case damage.)
657 2000-11-01 <tytso@snap.thunk.org>
659 * inode.c (ext2fs_flush_icache): Add new function
660 ext2fs_flush_icache() which flushes the internal inode
661 cache. Applications which modify the inode table blocks
662 directly must call this function.
664 2000-10-26 <tytso@snap.thunk.org>
666 * mkjournal.c: Add #include of netinet/in.h, since Solaris
667 requires it for ntohl().
669 * ext2_io.h (io_channel_write_byte): Add new interface to allow
670 callers to write specific byte ranges. This is an
671 optional interface, which not all IO channels may
674 * unix_io.c (unix_write_byte):
675 * test_io.c (test_write_byte): Add implementation of the
678 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
679 function which writes the primary superblock. If the IO
680 channel supports writing raw bytes directly, only fields
681 which were modified are written to the disk. This makes
682 it safe(r) to use utilities like tune2fs on a mounted
685 * freefs.c (ext2fs_free): Free the original superblock if it is
688 * openfs.c (ext2fs_open): Store a copy of the original superblock
691 * ext2fs.h: Add a field to store the original superblock in the
692 ext2 context structure.
694 2000-10-24 <tytso@snap.thunk.org>
696 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
697 don't need to use llseek).
699 2000-10-24 <tytso@valinux.com>
701 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
702 creating an ext3 journal on a filesystem.
704 2000-08-21 <tytso@valinux.com>
706 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
708 2000-08-22 <tytso@valinux.com>
710 * unix_io.c: Make massive changes to support a multiple block
711 writethrough cacheing.
713 * ext2_io.h: Added flags field to the io_channel structure.
715 2000-08-19 <tytso@valinux.com>
717 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
718 provides the function ext2fs_find_block_device(). This
719 function returns the pathname to a block device, given its
722 2000-07-13 <tytso@valinux.com>
724 * Release of E2fsprogs 1.19
726 2000-07-07 Theodore Ts'o <tytso@valinux.com>
728 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
729 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
730 list of filesystem flags supported by the library.
732 2000-07-04 Theodore Ts'o <tytso@valinux.com>
734 * ext2fs.h: Update to include latest journalling additions to the
737 * dll/jump.funcs: Add new jumptable entries for
738 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
739 ext2fs_badblocks_equal.
741 * tst_badblocks.c: Update test program to test
742 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
744 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
745 writes out bad blocks list to a file.
747 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
748 changes the callback function to take two additional
749 arguments; a private blind pointer supplied by the caller,
750 and pointer to a char * containing a pointer to the
753 * badblocks.c (ext2fs_badblocks_equal): Add new function which
754 returns true if two badblocks list are equal.
756 * Makefile.in: Remove explicit link of -lc in the shared library.
757 (It shouldn't be necessary, and is harmful in some cases).
759 2000-06-10 Theodore Ts'o <tytso@valinux.com>
761 * getsize.c (main): Add debugging code under #ifdef DEBUG
763 2000-05-27 Theodore Ts'o <tytso@valinux.com>
765 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
766 earlier, so that if there's an error reading it, we can
767 more cleanly back out of the operation.
769 2000-05-25 <tytso@snap.thunk.org>
771 * getsize.c (ext2fs_get_device_size): Use open64() instead of
772 open() if it exists. Under linux, manually define the
773 ioctl for BLKGETSIZE if it isn't already defined and it's
776 * unix_io.c (unix_open): Use open64() instead of open() if it
779 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
780 available (and prototypes are defined) use it in
781 preference to llseek.
783 * Makefile: Add hack dependency rule so that parallel makes work
786 2000-05-18 Theodore Ts'o <tytso@valinux.com>
788 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
790 2000-04-03 Theodore Ts'o <tytso@valinux.com>
792 * block.c: Readibility tweak in conditionals involving
795 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
796 how to define __s64 and __u64. Turn off "compression is
797 experimental" warning if the cpp macro
798 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
800 2000-02-11 <tytso@snap.thunk.org>
802 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
803 Conditionally include Compression as a supported type if
804 ENABLE_COMPRESSION (via --enable-compression) is turned on.
806 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
808 2000-02-08 <tytso@snap.thunk.org>
810 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
811 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
812 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
813 Change to return the previous state of the bit that is
814 being marked or unmarked. For speed optimization.
816 2000-02-02 Theodore Ts'o <tytso@valinux.com>
818 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
820 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
821 needed any more; we know it will always be i_generation.
822 Add support for swapping the high bits of the uid and gid.
824 1999-11-19 <tytso@valinux.com>
826 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
827 counts if the link was successful. Patch suggested by
830 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
831 the source directory.
833 1999-11-10 <tytso@valinux.com>
835 * Release of E2fsprogs 1.18
837 1999-11-08 <tytso@valinux.com>
839 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
840 since ext2fs_badblocks_list_free was moved to freefs.c.
842 * tst_badblocks.c: Use the newer badblocks API names. Add
843 duplicate blocks to the test inputs to test dealing with
844 adding blocks which are already in the badblocks list.
846 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
847 of the list, use a shortcut O(1) operations instead of an
848 O(n) operation. (Idea suggested by David Beattie.)
850 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
851 of badblocks_list_free(), to save a procedure call.
853 1999-10-26 <tytso@valinux.com>
855 * Release of E2fsprogs 1.17
857 1999-10-26 <tytso@valinux.com>
859 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
860 seem to handle ~0UL the same way as they used to.
862 1999-10-25 <tytso@valinux.com>
864 * nt_io.c (_OpenNtName): Open the device using
865 FILE_SYNCHRONOUS_IO_NONALERT instead of
866 FILE_SYNCHRONOUS_IO_ALERT
867 (nt_open): At the end of the device open routine, unlock
868 the drive but do not dismount it.
870 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
873 1999-10-22 <tytso@valinux.com>
875 * Release of E2fsprogs 1.16
877 1999-10-22 <tytso@valinux.com>
879 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
881 * link.c (ext2fs_link): This call now uses the low three bits of
882 the flags parameter to pass the directory filetype
883 information; it will set the directory entry FILETYPE
884 information if the filesystem supports it.
886 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
887 option is set, then create the '.' and '..' entries with
888 the filetype set to EXT2_FT_DIR.

892 * nt_io.c: New file which supports I/O under Windows NT.
894 1999-09-07 <tytso@valinux.com>
896 * ext2fs.h: Add new fields for journalling and define new
897 feature bits used by newer filesystems: IMAGIC_INODES,
898 HAS_JOURNAL, RECOVER.
900 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
901 we update the inode block count and size files so that the
902 block count field is updated correctly when we create an
905 1999-07-18 Theodore Ts'o <tytso@valinux.com>
907 * Release of E2fsprogs 1.15
909 1999-06-23 <tytso@valinux.com>
911 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
912 kernels that use i_generation instead of i_version. Patch
913 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
915 1999-06-21 <tytso@valinux.com>
917 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
918 directory entry before calling the callback function.
919 This should prevent some core dumps of insufficiently
920 paranoid callback functions.
922 1999-05-29 <tytso@rsts-11.mit.edu>
924 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
926 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
927 that we don't handle writing yet (we do). Fixed bug where
928 we weren't allocating a big enough buffer for ext2_bmap.
930 1999-05-03 <tytso@rsts-11.mit.edu>
932 * openfs.c (ext2fs_open): Check to make sure that the number of
933 blocks per group is not zero --- if so, it must be a bad
936 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
938 * Release of E2fsprogs 1.14
940 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
942 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
943 the inode number is zero; if it's zero, return
944 EXT2_ET_BAD_INODE_NUM.
946 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
948 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
949 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
952 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
954 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
955 non-Linux case to use EINVAL by default, unless it isn't
956 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
959 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
961 * Release of E2fsprogs 1.13
963 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
965 * Makefile.in: Updated dependencies.
967 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
969 * initialize.c (ext2fs_initialize): Make sure that we allocate
970 enough inodes so that we can make a valid filesystem.
972 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
974 * rw_bitmaps.c: Fixed signed/unsigned warnings.
976 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
977 function declaration.
979 * dblist.c (make_dblist): Add safety check in case the dblist
980 pointer passed in is null (in which case, assign it to
981 fs->dblist). Fixed some signed/unsigned warnings.
983 * bmap.c: Make addr_per_block be of type blk_t to avoid
984 signed/unsigned warnings.
986 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
987 function declaration.
989 * get_pathname.c (get_pathname_proc): Use return value from
990 ext2fs_get_mem, instead of checking if &gp->name is
993 * dir_iterate.c (ext2fs_process_dir_block):
994 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
995 from the function declaration.
997 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
998 return the error directly instead of jumping to the
999 cleanup routine, since we don't need to do any cleanup.
1001 * alloc_table.c (ext2fs_allocate_group_table): Make this
1002 function take a dgrp_t for its group argument.
1004 * ext2fs.h: Make dgrp_t an __u32 type, and make
1005 fs->desc_group_count be of type dgrp_t.
1007 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1009 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1010 than 10 blocks when we need to expand the size of the
1013 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1015 * Release of E2fsprogs 1.12
1017 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1019 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1020 appropriate for all of the block group copies, so that
1021 it's clear where the beginning of the filesystem is on the
1022 disk. (For when the partition table gets scrod.)
1024 * ext2fs.h: Change the name of the feature from
1025 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1026 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1028 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1030 * inode.c (get_next_blockgroup): Fix bug where if
1031 get_next_blockgroup() is called early because of a missing
1032 inode table in a block group, the current_inode counter
1033 wasn't incremented correctly.
1035 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1037 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1038 against a completely trashed bad block inode.
1040 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1042 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1043 the stride length hits a bad value, we retry the block
1044 allocation starting at the beginning of the block group.
1046 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1047 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1048 e2_blkcnt_t to avoid collision with LFS API.
1050 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1052 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1053 way that avoids overflows on disk sizes greater than 4GB.
1055 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1057 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1058 return type for comparison functions for qsort.
1060 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1063 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1065 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1068 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1069 evade a potential problem with glibc's header files trying
1070 to spike out linux/types.h.
1072 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1073 include the old size of the memory, which is needed for
1074 some braindamaged memory allocation systems that don't
1077 * badblocks.c (ext2fs_badblocks_list_add):
1078 bb_inode.c (clear_bad_block_proc):
1079 dblist.c (ext2fs_add_dir_block):
1080 icount.c (insert_icount_el):
1081 irel_ma.c (ima_put):
1082 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1083 pass the old size of the memory to be resized to
1084 ext2fs_resize_mem().
1086 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1088 * Makefile.in: Change to use new installation directory variables
1089 convention. Fix uninstall rules to take $(DESTDIR) into
1092 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1094 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1095 with 32 bit longs, then we need to manually define __s64
1096 and __u64, since the current kernel header files don't
1097 define these if __STRICT_ANSI__ is defined. This is a
1098 problem if we are compiling with full GCC warnings, since
1099 we do need 64 bit support.
1101 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1102 since we're not using ext2fs_move_blocks() and there
1103 is some question as to its usefulness in its current
1106 * bmap.c (block_bmap): Remove unused function.
1108 * bmove.c (process_block): Fix -Wall warning.
1110 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1112 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1113 contain the offset into the inode.i_blocks array when
1114 ref_block is zero. Since we haven't done a formal
1115 release of e2fsprogs since block_iterate2 was first
1116 introduced, I removed block_iterate2, and renamed
1117 block_iterate3 to be block_iterate2.
1119 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1120 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1121 use of block_iterate and block_iterate2 to
1122 block_iterate2 with the new prototype for the
1123 interator function. (using blkcnt_t forr blockcount)
1125 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1127 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1128 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1129 conditional defines of new features COMPAT_DIR_PREALLOC,
1130 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1131 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1132 the library to declare that we support COMPAT_DIR_PREALLOC,
1133 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1135 * fileio.c: Rename function ext2fs_file_llseek to be
1136 ext2fs_file_lseek, which is more accurate.
1138 * block.c: Add new function ext2fs_block_iterate3 which calls
1139 the iterator function with the blockcount argument of
1140 type blkcnt_t. This version of the function is
1141 allowed to handle large files; the other fucntions are
1144 * ext2fs.h: Add new type blkcnt_t
1146 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1148 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1149 field wasn't getting correctly incremented for sparse
1150 files when the indirect or doubly-indirect block
1151 specified in the inode was zero.
1153 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1155 * unlink.c (unlink_proc):
1156 * lookup.c (lookup_proc):
1157 * link.c (link_proc):
1158 * get_pathname.c (get_pathname_proc):
1159 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1160 from dirent->name_len, so it can be used for other
1163 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1164 and indicate that we have support for this incompatible
1167 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1169 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

1174 number of directories when the block group information is
1177 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1179 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1180 inode table is missing so that we catch the case where the
1181 first block group is missing.
1183 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1186 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1188 * ext2_io.h, ext2fs.h: Protect against being included multiple times.

1192 * test_io.c (test_flush): Add a debugging printf when the flush
1195 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1196 read in, return right away.

1200 * bitops.h: Don't try to do i386 inline asm functions if the
1203 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1204 instead of linux/types.h, and e2_bitops.h instead of
1207 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1210 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1212 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1213 so that we don't need to call get_next_blockgroup() the
1214 first time around. Saves a bit of time, and prevents us
1215 from needing to assign -1 to current_group (which is an
1218 * icount.c (insert_icount_el): Cast the estimated number of inodes
1219 from a float to an ino_t.
1221 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

1231 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1232 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
1233 defined, then assume all of the
1234 ext2-specific header files are in a flat directory.
1236 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1237 all assignments from void * to be compatible with C++.
1239 Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1241 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to

1255 unlink.c: Change private to be priv_data (to avoid C++
1258 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1260 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1261 paranoid about validating the directory counts from the
1262 block group information.
1264 * all files: Don't include stdlib.h anymore; include it in
1265 ext2_fs.h, since that file requires stdlib.h
1267 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1269 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1270 bitmap is loaded, and return an error if it is not.
1271 (expand_dir_proc): Only use ext2fs_write_dir_block when

1321 physical block number.
1323 * fileio.c: New file which implements simple file reading and
1326 * alloc.c (ext2fs_alloc_block): New function which allocates a
1327 block, zeros it, and updates the filesystem accounting

1386 * io.h: Change the prototype of ext2fs_llseek() to use int's
1387 instead of unsigned int's.
1389 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1390 to make life easer for GNU Libc 2.
1392 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1393 filesystem has its bitmaps stored as 32-bit words with bit
1394 0 as the LSB of each word. Thus a bitmap with only bit 0
1395 set would be, as a string of bytes, 00 00 00 01 00 ... To
1396 cope with this, we byte-reverse each word of a bitmap if
1397 we have a big-endian filesystem, that is, if we are *not*
1398 byte-swapping other word-sized numbers.

1518 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1519 ext2fs_badblocks_list_test would test the list (and exceed
1520 array boundaries) if there were no bad blocks on the bad
1521 blocks list. (Showed up when user tried: mke2fs -c -b 4096).

1580 interface io_channel_bumpcount() to bump the refcount.
1582 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1596 block_iterate_tind): If there are holes in the indirect,
1597 doubly indirect, or triply indirect blocks, increment the
1598 block count field automatically.
1600 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1602 * Release of E2fsprogs version 1.09
1604 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1606 * version.c (ext2fs_parse_version_string): Check the passed in
1607 version string (instead of the hard-coded one).
1609 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1610 greater filesystem size, clamp it to prevent allocating a
1611 block or inode bitmap beyond the filesystem.
1613 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1614 overhead calculation was accidentally removed.
1616 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1618 * Release of E2fsprogs version 1.08
1620 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1622 * dblist.c (ext2fs_set_dir_block): New function which sets the
1623 block of a dblist entry, given the directory inode and
1626 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1628 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1629 inode bitmaps at staggered locations across the block
1630 groups, to avoid concentrating the bitmaps on a small
1631 number of disks when using striped RAID arrays.
1633 * initialize.c (ext2fs_initialize): By default, choose the maximum
1634 possible number of blocks per group (based on the size of
1635 the bitmaps in the blocksize).
1637 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1639 * initialize.c (ext2fs_initialize): Add support for
1640 EXT2_COMPAT_SPARSE_SUPER feature.
1642 * closefs.c (ext2fs_bg_has_super): New function to determine
1643 whether or a particular block group should have a
1644 superblock and block group descriptor. Used for the
1645 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1646 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1647 or not the superblock should be written out for the block
1650 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1651 for sparse duplicate superblocks.
1653 * version.c (ext2fs_get_library_version): New function which
1654 returns the library version.
1656 * version.c (ext2fs_parse_version_string): New function which
1657 parses a version string and returns a version number,
1658 so application programs can compare version numbers as
1661 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1663 * icount.c (ext2fs_create_icount): Change function so that it also
1664 takes a new argument which contains a "hint" icount
1665 structure. This "hint" icount allows the create function
1666 to set up the sorted list in advance. This reduces
1667 significantly the amount of data moving needed to insert
1668 these inodes into the list later.
1670 * icount.c (ext2fs_icount_validate): New function which validates
1671 that the icount structure's rep invariant.
1673 * icount.c (get_icount_el): Completely revamped implementation
1674 to subsume put_icount_el(). Put_icount_el() used to
1675 use an O(N) implementation to insert in the middle
1676 of the icount list. It now uses a O(ln N) to search
1677 for where the icount should be inserted, and then uses
1678 a memcpy to move the list down (instead of a for loop).
1680 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1681 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1682 to see if the inode is within bounds; if it isn't, return
1685 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1686 when a bad inode number is passed to test_generic_bitmap
1687 to be EXT2FS_TEST_ERROR instead of the wrong
1688 EXT2FS_UNMARK_ERROR.
1690 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1692 * Release of E2fsprogs version 1.07
1694 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1696 * Makefile.in (ELF_VERSION): Change version to be 2.2
1698 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1700 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1701 ext2fs_fast_test_block_bitmap_range().
1703 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1704 ext2fs_test_block_bitmap_range: New inline functions which
1705 test to see whether a contiguous range of blocks is
1708 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1710 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1711 use ext2fs_badblocks_* instead of badblocks_*
1713 * bb_compat.c: New file which translates between old badblocks_*()
1714 names to ext2fs_badblocks_*()
1716 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1717 link.c (since e2fsck doesn't use ext2fs_unlink()).
1719 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1720 bitmap resizing routine moved from bitmaps.c, since e2fsck
1721 doesn't need to use this function.
1723 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1724 since e2fsck only needs ext2fs_lookup.
1726 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1728 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1729 already set; this is needed so that programs like dump
1730 which use the inode scan functions will deal with
1731 filesystems that have bad blocks in the inode table.
1733 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1735 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1736 Moved to ext2fsP.h, since it doesn't need to be part of
1737 the public interface.
1739 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1741 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1743 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1744 directory block list abstraction. (Code moved from
1747 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1748 to inode.c (since no one else should be peeking inside it!)
1750 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1752 * openfs.c (ext2fs_open): Check the feature set in the ext2
1753 superblock, and refuse to open filesystems if they contain
1754 incompatible features. (Can be overriden with the
1757 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1759 * block.c (ext2fs_block_iterate2): Added new function
1760 ext2fs_block_iterate2 which changes the function
1761 signature of the callback function to include the
1762 referencing block and offset.
1764 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1765 ext2fs_inode_scan_goto_blockgroup which allows an
1766 application to jump to a particular block group while
1767 doing an inode scan.
1769 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1771 * dirblock.c: Include string.h, since we use memcpy().
1773 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1775 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1776 a long not an int; this doesn't matter on i386 machines,
1777 but it does on Alpha's.
1779 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1781 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1782 table pointer is NULL, then return an error indicating
1783 that the inode table is missing.
1784 (get_next_blockgroup, get_next_blocks,
1785 ext2fs_get_next_inode): Don't treat a missing inode table
1786 as permanent error. Return MISSING_INODE_TABLE, but as an
1787 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1789 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1790 ext2fs_write_inode_bitmap): If the inode or block bitmap
1791 block is zero, then don't write out the inode or block
1792 bitmap. The idea here is to avoid stomping on the
1794 (read_bitmaps): If the inode or block bitmap block is
1795 zero, then fill in that portion of the inode or block
1796 bitmap with all zeros.
1798 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1799 blocks in inode table when the inode table size is
1800 non-standard (and can therefore span blocks).
1802 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1804 * alloc.c (ext2fs_new_block): Fix fencepost error in
1805 ext2fs_new_block; make sure we don't try to allocate the
1806 first block beyond the end of the filesystem.
1808 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1810 * inode.c (check_for_inode_bad_blocks): New function called by
1811 get_next_blocks() to avoid reading in bad blocks marked in
1812 fs->badblocks. Inodes located in bad blocks are returned
1813 by ext2fs_get_next_inode() returns the error code
1814 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1816 * alloc_tables.c (ext2fs_allocate_tables): New function which
1817 performs the part of mke2fs's job of allocating the
1820 * test_io.c (test_close): IO manager which is used for testing
1823 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1825 * inode.c (ext2fs_get_next_inode): Separate out the function of
1826 setting up for a new block group to get_next_blockgroup().
1827 Separate out the function of reading in blocks of the
1828 inode table to get_next_blocks().
1830 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1832 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1833 blocks to the badblock list in sorted order. This allows
1834 badblocks_list_test to be coded using a binary search for
1837 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1839 * Release of E2fsprogs version 1.06
1841 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1843 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1844 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1847 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1848 set, then only write out the master superblock.
1850 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1852 * block.c (ext2fs_block_iterate): Fixed bug which caused
1853 block_iterate to fail to handle HURD created filesystems;
1854 it tested the inode translator field before the inode was
1857 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1859 * initialize.c (ext2fs_initialize): Make sure the description for
1860 the inode bitmap is set correctly.
1862 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
1864 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1866 * Release of E2fsprogs version 1.05
1868 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1870 * initialize.c: Override the kernel's idea of default
1871 checkinterval from 0 (never) to 180 days.

1875 * namei.c (ext2fs_namei_follow): New function which follows
1876 symbolic link (if any) at the target.
1878 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1880 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
1881 for shortcut function fs->read_inode() and fs->write_inode().
1882 Added inode_cache to reduce CPU time spent in doing
1885 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
1888 * namei.c (ext2fs_follow_link): New function.
1889 (ext2fs_namei): Extended to have support for chasing
1890 symbolic links. ext2fs_namei() still returns an inode
1891 which is a symbolic link. Symbolic links are only chased
1892 while resolving the containing directory. To chase
1893 symbolic links of the final result, use
1894 ext2fs_follow_link().
1896 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1898 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1900 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1901 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
1903 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1905 * initialize.c (ext2fs_initialize): On systems where the byte
1906 order is not i386 compatible, set the swap_byte flag.
1908 * inode.c (inocpy_with_swap): Check to see if inode contains a
1909 fast symlink before swapping the inode block fields. This
1910 required adding a new argument to inocpy_with_swap to
1911 determine whether the mode field is in host order or not.
1913 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1915 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1916 the sparc, if EXT2_STD_BITOPS set, use the standard
1917 i386-compatible bitmask operations, instead on the
1918 non-standard native bitmask operators.
1920 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1922 * block.c (ext2fs_block_iterate): Cause block iterator to return
1923 the HURD translator block (along with everything else).
1924 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1925 iterator, then don't return any meta data blocks
1926 (including the HURD translator).
1928 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1930 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1932 * uuid.c: New file, containing UUID utility functions.
1934 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1936 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1938 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1940 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1942 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1944 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1945 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1946 that's a basic value that must be correct for the rest of
1947 the library to work.
1949 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1952 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1954 * Release of E2fsprogs version 1.04

1958 * Release of E2fsprogs version 1.03
1960 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
1962 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
1963 Change the m68k bit numbering for bitmasks to match with
1964 the bit numbering used by all other ext2 implementations.
1966 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1968 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

1982 the passed in size is *really* too small.
1984 * alloc.c (ext2fs_new_inode):
1985 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
1988 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
1990 * getsize.c (ext2fs_get_device_size): Open the device read-only
1991 when trying to determine its size.
1993 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1995 * Release of E2fsprogs version 1.02
1997 Sat Dec 9 09:57:50 1995 <tytso@rsts-11.mit.edu>

2000 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2001 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2002 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2003 to avoid conflicts with with kernel include files. Also
2004 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2007 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2009 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
2011 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around

2018 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
2020 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
2023 * closefs.c: #include <string.h> to pick up memset() declaration
2025 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
2027 * Makefile.in: Added support for BSD shared libraries.
2029 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2032 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2034 * unix_io.c (unix_open): Add a double check; if the passed in name
2035 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2037 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2039 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
2041 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
2044 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
2046 * getsize.c (ext2fs_get_device_size): Add support for reading the
2047 partition size from a BSD disk label.
2049 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2051 * getsize.c (ext2fs_get_device_size): New function that determins
2052 the size of a device. Used by mke2fs and e2fsck.
2054 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
2056 * Makefile.in (install): Install static libraries in $(ulibdir)
2057 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
2059 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
2061 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2062 Move these functions to freefs.c.
2064 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2065 descriptors shadow memory to keep purify quiet. (This
2066 also has the nice benefit that the unused portion of the
2067 shadow descriptors are zeroed out.)
2069 * dirblock.c (ext2fs_write_dir_block): We need to use
2070 dirent->rec_len *before* it's byteswapped to find the
2071 location of the next directory structure!
2073 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2074 cause ext2fs_new_inode to loop infinitely if we're trying
2075 to allocate an inode in group #0 and there are no free
2076 inodes at all in the system.
2078 * closefs.c: #include <errno.h> if it exists.
2080 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2082 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2093 * namei.c (process_dir_block):
2094 * mkdir.c (ext2fs_mkdir):
2095 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
2096 to read/write the directory block.
2098 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
2099 file containing functions for reading and writing
2100 directory blocks (byte swapping if necesssary)
2102 * block.c (block_iterate_ind, block_iterate_dind,
2103 block_iterate_tind): Byte swap the block addresses if
2104 EXT2_SWAP_BYTES is set (and swap them back before writing
2107 * inode.c (inocpy_with_swap): New function.
2108 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
2109 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2111 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2112 the superblock and group descriptors before writing it out.
2114 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2115 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2116 and group descriptors.
2118 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2119 to desp ext2 filesystem structures.
2121 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2122 supplied by Pete A. Zaitcev so that the C language
2123 versions of these functions are more portable. They will
2124 now work on both little and big endian systems, and the
2125 assumption that 32-bit integers are used is gone.
2127 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2128 doing byte swapping.
2130 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2131 byte swapping should take place.
2133 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
2135 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,

2140 Added new error codes.
2142 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
2144 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2145 if the magic number is correct, it will be allocated.
2147 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2149 * block.c (block_iterate_ind, block_iterate_dind,
2150 block_iterate_tind): Don't recompute block_nr each loop;
2151 just increment it! Factor check of BLOCK_FLAG_APPEND out
2152 of the loop. Factor mask of BLOCK_CHANGED into changed
2153 variable out of the loop. (block_iterate_ind, in
2154 particular, gets called a lot, so every little
2155 optimization helps.)
2157 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2159 * block.c (block_iterate_ind, block_iterate_dind,
2160 block_iterate_tind): Precompute limit of loop to speed up
2161 block_iterate_ind and company.
2163 * bitops.h (ext2fs_fast_mark_block_bitmap,
2164 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
2165 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2166 ext2fs_fast_test_inode_bitmap): Add fast version of these
2167 functions, which don't do range checking.
2169 * bitops.h (ext2fs_get_block_bitmap_start,
2170 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2171 ext2fs_get_inode_bitmap_end): Add new accessor functions
2172 which return the start and end points of the bitmaps.
2174 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2176 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2177 instead of llseek. The errno if the offset is too large
2178 and lseek is not supported should be EINVAL, not -EINVAL.
2180 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2182 * Makefile.in: Added support for ELF shared libraries.
2183 Fixed typos in the compilation rules.
2184 (distclean): Added Makefile.

2190 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2192 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
2194 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2196 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2198 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2199 the S_*, which are normally defined in <sys/stat.h>. This
2200 allows us to compile e2fsprogs on a non-Linux system,
2201 which may have a different value for S_IFDIR.
2203 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2205 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2206 this is a user-mode application!
2208 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2210 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2211 __linux__ so that non-linux systems won't see it.
2213 * alloc.c: Include <errno.h> if possible.
2214 * badblocks.c: Ditto.
2215 * bb_inode.c: Ditto.
2218 * expanddir.c: Ditto.
2219 * get_pathname.c: Ditto.
2220 * initialize.c: Ditto.
2227 * rw_bitmaps.c: Ditto.
2230 * Makefile.in: Rewritten to conform to GNU coding standards and
2231 support separate compilation directories.
2233 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2235 * initialize.c (ext2fs_initialize): Don't allow more than one
2236 bitmaps's worth of inodes in a group.
2238 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2240 * llseek.c (ext2_llseek): Added error checking to the llseek()
2241 compat code to protect against overflow. This only
2242 applies to 1.0 and early 1.1 kernels, which don't support
2243 the llseek() system call.
2245 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2247 * unix_io.c (unix_open): Initialize the read_error and write_error
2248 io_channel pointers to be null.
2250 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2251 found, clear it but don't try to update the filesystem
2252 accounting information, since that's hopeless anyway.
2254 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2255 bloblock_iterate_tind): Check to see if the indirect blocks are
2256 valid before trying to read them.

2259 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2261 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2262 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2263 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2264 illegal block or inode number is passed in, return instead
2265 of trying to test, set, or clear the bit.
2267 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2269 * Makefile: Added a dummy install target in case shared libraries
2272 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2274 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

2279 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
2280 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
2281 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
2282 ext2fs_free_block_bitmap): Add magic number checking for
2283 the inode and block bitmaps.
2285 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2286 magic number for a block bitmap instead of an inode bitmap.
2288 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
2289 magic number checking for the inode_scan structure.

2292 badblocks_list_test, badblocks_list_iterate_begin,
2293 badblocks_list_iterate, badblocks_list_iterate_end): Add
2294 magic number checking for the badblocks_list and
2295 badblocks_iterate structures.
2297 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
2298 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
2299 unix_write_blk, unix_flush): Add magic number checking
2300 both for io_channel structure and unix_private_data
2303 * openfs.c (ext2fs_open): Add check for io_manager structure's
2306 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2307 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2308 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2309 * read_bb.c (ext2fs_read_bb_inode):
2310 * read_bb_file.c (ext2fs_read_bb_FILE):

2321 ext2fs_allocate_block_bitmap):
2322 * bb_inode.c (ext2fs_update_bb_inode):
2323 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):

2325 * closefs.c (ext2fs_close, ext2fs_flush):
2326 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2331 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2332 openfs.c into its own file.
2334 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2335 structure magic numbers.
2337 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2338 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2339 someone uses the -b option to specify the use of the backup
2340 superblock --- this usually means that the main superblock is
2344 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2345 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2346 revision level to the superblock.
2348 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2355 * initialize.c: Completely revamped the inode and block bitmap
2356 structures, so that they can be better chance of being extensible
2357 in a shared library. They are now their own type, instead of
2358 being a char *. Also, the function signatures of
2359 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2360 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2361 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2362 changed to eliminate the ext2_filsys argument, since it is no
2365 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2367 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2368 system call if available.
2370 * llseek.c: new file. This is the stub calling the llseek system
2371 call which allows supports for 2GB+ file systems.
2373 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2374 the creator operating system.
2376 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2378 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2379 the group descriptor statistics in addition to everything else.
2380 This relieves mke2fs of the responsibility of doing it.
2382 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2383 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2384 not the generic C function equivalents should be included or not.
2386 * openfs.c (ext2fs_open): If a superblock is specified, then use
2387 the backup group descriptors that go along with this superblock,
2388 instead of using the primary group descriptors. This allows
2389 e2fsck to recover filesystems where the primary group descriptors
