1 2002-06-27 Theodore Ts'o <tytso@mit.edu>
3 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
4 Add appropriate fallbacks in this case.
6 2002-06-26 Theodore Ts'o <tytso@mit.edu>
8 * dirhash.c (ext2fs_dirhash): Change function signature to support
9 a hash seed, and to return the minor hash (for 64-bit hash
10 support). Add support for the half MD4, half MD4 with
11 seed, and half MD4 with seed and 64 bits.
13 2002-06-15 Theodore Ts'o <tytso@mit.edu>
15 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
17 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
19 * ext2_fs.h: Add macros for maximum block/inode counts:
20 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
21 and EXT2_MAX_INODES_PER_GROUP.
23 * openfs.c (ext2fs_open): Check that the number of blocks in a group
24 is less than 2^16, otherwise we need an INCOMPAT flag (not
25 in existence yet, if ever) to open such a filesystem.
27 * initialize.c (ext2fs_initialize): Limit the number of blocks and
28 inodes in a group to less than 2^16.
30 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
32 * ext2_fs.h: Further minor cleanups of the header. Consolidate
33 some checks for __KERNEL__ into one place.
35 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
37 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
38 the EXT2_SB() macro instead. Remove kernel function
39 prototypes also. This matches the 2.5 kernel, and
40 is also cleaner for other reasons. Whitespace cleanup.
42 2002-05-21 Theodore Ts'o <tytso@mit.edu>
44 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
46 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
48 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
50 * initialize.c (ext2fs_initialize): Remove assumption that
51 blocksizes are always <= 4k.
53 2002-05-11 Theodore Ts'o <tytso@mit.edu>
55 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
56 silently if inode pointer is NULL (and ext2fs_bmap is
57 expected to read the inode itself).
59 2002-04-27 Theodore Ts'o <tytso@mit.edu>
61 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
62 file we are checking is a block device file before looking
63 at st_rdev, since it's not valid for normal files.
64 (is_swap_device): Move so that it is outside the
65 HAVE_MNTENT_H, so that it is always built.
67 2002-03-11 Theodore Tso <tytso@mit.edu>
69 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
70 functions which take an extra flags argument. The flag
71 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
72 field is byte swampped on big-endian machines, since in
73 the V2 structure, name_len is a char field which is
74 doesn't need to be byte swapped --- except if an
75 old-style kernel had byte-swapped the name_len field
76 as part of the V1 structure.
78 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
80 * dirhash.c (ext2fs_dirhash): New function which calculates the
81 hash for a filename in an indexed directory.
83 2002-03-08 Theodore Tso <tytso@mit.edu>
85 * Release of E2fsprogs 1.27
87 2002-03-07 Theodore Tso <tytso@mit.edu>
89 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
91 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
92 tst_byteswap.c: Fix gcc -Wall complaints
94 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
95 (From Philipp Thomas <pthomas@suse.de>)
97 2002-02-25 Theodore Tso <tytso@mit.edu>
99 * ext2_fs.h: Add structure definitions for the directory indexing
102 2002-02-23 Theodore Tso <tytso@mit.edu>
104 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
105 it doesn't break things on mis32, sparc32, and alpha
108 2002-02-21 Theodore Tso <tytso@mit.edu>
110 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
111 we were missing an fclose().
113 2002-02-20 Theodore Tso <tytso@mit.edu>
115 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
116 abstraction interface which exports an ext2 inode.
118 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
119 as a public interface. Change void * to const void * in
120 ext2fs_file_write's interface.
122 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
123 conditional; save a few bytes.
125 2002-02-12 Theodore Tso <tytso@mit.edu>
127 * Makefile.in (tst_badblocks): Add some extra .o files when
128 linking the debugging program tst_badblocks which are
129 needed if we aren't compiling with inline functions enable.
131 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
132 define away __inline__ since it may not be supported.
134 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
135 stripped down jbd_debug that doesn't use variadic
136 arguments. This will cause warnings under AIX, but things
139 2002-02-03 Theodore Tso <tytso@thunk.org>
141 * Release of E2fsprogs 1.26
143 2002-02-03 Theodore Tso <tytso@mit.edu>
145 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
146 so that the number of directories in use is adjusted
149 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
150 which optionally will modify the number of directories
153 2002-01-03 Theodore Tso <tytso@mit.edu>
155 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
156 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
157 which will return deleted directory entries.
158 ext2fs_dir_iterate2 takes a new callback function which
159 is identical with the one used by
160 ext2fs_dblist_dir_iterate(). If the directory entry is
161 deleted, the callback function will be called with the
162 entry paraemter set to DIRENT_DELETED_FILE.
164 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
165 ext2fs_block_alloc_stats): New functions which update
166 block/inode allocation statistics in the bitmaps, block
167 group descriptors, and superblock.
169 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
170 expanddir.c (expand_dir_proc), bb_inode.c
171 (clear_bad_block_proc, set_bad_block_proc,
172 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
173 Update to use new block/inode allocation statistics.
175 2001-12-24 Theodore Tso <tytso@mit.edu>
177 * ismounted.c (is_swap_device): New function used by
178 ext2fs_check_if_mounted and ext2fs_check_mount_point which
179 determines whether or not the specified device is a swap
180 device by using /proc/swaps. More bulletproofing for
181 idiotic/careless system administrators!
183 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
184 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
185 field to struct_ext2_filsys, umask. This field is
186 initialize to 022, and affects ext2fs_mkdir in the obvious
187 way. (In the future umask should also affect new file
188 creation routines, but the fileio functions don't
189 currently support this yes.)
191 * ismounted.c (check_mntent_file): Stat all of the entries in
192 /etc/mtab and/or /proc/mounts in order to catch dim-witted
193 system administrators who might have created alias
196 2001-12-23 Theodore Tso <tytso@mit.edu>
198 * Makefile.in, jfs_user.h: Move linux/jbd.h to
199 ext2fs/kernel-jbd.h, to avoid using the system header
200 file version of hbd.h when using diet glibc (since it
201 forcibly adds /usr/include to the beginning of the
202 include search path.)
204 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
205 include/linux directory.
207 2001-12-16 Theodore Tso <tytso@mit.edu>
209 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
210 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
211 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
213 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
216 2001-12-03 Theodore Tso <tytso@mit.edu>
218 * unix_io.c (unix_open): Make sure the ulimit workaround works
219 regardless of the version of glibc which is used to
222 2001-11-26 Theodore Tso <tytso@mit.edu>
224 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
225 trying to unset the filesize limit if at all possible,
226 if a block device is getting opened. (The filesize limit
227 shouldn't be applied against writes to a block device, but
228 starting in 2.4.10, the kernel is doing this.)
230 2001-11-05 Theodore Tso <tytso@mit.edu>
232 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
233 file on adding a journal to an already-mounted filesystem,
234 try to clear the ext2 file attributes on an already
235 existing .journal file so that we don't fail if on a
236 partially added journal to the filesystem.
238 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
239 which signals that a particular inode should not have the
240 last bits of data (the "tail") be merged with another
241 file. This is necessary to keep LILO happy.
243 2001-09-20 Theodore Tso <tytso@thunk.org>
245 * Release of E2fsprogs 1.25
247 2001-09-16 Theodore Tso <tytso@mit.edu>
249 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
250 which was breaking the build on the Hurd. (Addresses
253 2001-09-13 Theodore Ts'o <tytso@mit.edu>
255 * ismounted.c (check_mntent_file): We now validate the entry in
256 /etc/mtab to make sure the filesystem is really mounted,
257 since some broken distributions (read: Slackware) have
258 buggy boot scripts that don't initialize /etc/mtab before
259 checking non-root filesystems. (Slackware also doesn't
260 check the root filesystem separately, and reboot if the
261 root filesystem had changes applied to it, which is
262 dangerous and broken.)
264 2001-09-02 Theodore Tso <tytso@thunk.org>
266 * Release of E2fsprogs 1.24a
268 2001-08-30 Theodore Tso <tytso@thunk.org>
270 * Release of E2fsprogs 1.24
272 2001-08-30 Theodore Tso <tytso@valinux.com>
274 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
275 changes, since the ioctl number has been reused by another
278 2001-08-15 Theodore Tso <tytso@valinux.com>
280 * Release of E2fsprogs 1.23
282 2001-08-05 Theodore Tso <tytso@valinux.com>
284 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
285 version of the bitmap test routines to speed up these
286 routines. (At some point I may want to make these
287 routines use the find_first_bit functions, but that will
288 add a lot of complexity since it means that these
289 functions will have to break the bitmap abstraction
290 boundary. It's not clear it's worth it.)
292 * mkjournal.c (mkjournal_proc): Remember the last block allocated
293 to speed up ext2fs_new_block().
295 2001-07-29 Theodore Tso <tytso@valinux.com>
297 * finddev.c (scan_dir): Fix memory leak; we weren't calling
298 closedir() when exiting the function in all cases.
300 2001-07-27 Theodore Tso <tytso@valinux.com>
302 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
303 block usable in the journal for external journals to be 2
304 or 3, depending on the blocksize, so that the existing
305 kernel code does the right thing.
307 * getsize.c (ext2fs_get_device_size): Add support for the
308 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
309 from Ben LaHaise, but it's likely this interface won't
312 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
313 when writing the journal superblock, too. (Oops! Needed
314 to make 1k filesystems with external journal to work.)
316 2001-07-26 Theodore Tso <tytso@valinux.com>
318 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
319 to find the journal superblock if the blocksize is 1024.
321 2001-07-21 Theodore Tso <tytso@valinux.com>
323 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
325 2001-07-20 Theodore Tso <tytso@valinux.com>
327 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
328 attribute block, set the filesystem changed bit.
330 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
331 Comment out these functions since we're not using them.
333 2001-07-10 Theodore Tso <tytso@valinux.com>
335 * closefs.c (write_primary_superblock): After writing changes to
336 the primary superblock, update the original superblock
337 copy so we don't have to re-write those changes in the
339 (ext2fs_flush): Clear the superblock dirty flag after
340 we've flushed out changes to disk.
342 2001-07-07 Theodore Tso <tytso@valinux.com>
344 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
345 to avoid register conflicts when compiling in PIC mode.
347 2001-07-04 Theodore Tso <tytso@valinux.com>
349 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
350 Add new functions (C and in i386 assembler) which quickly
351 find bits set in a bitmask.
353 2001-06-23 Theodore Tso <tytso@valinux.com>
355 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
356 ext2_ext_attr.h and ext_attr.c for extended attributes
359 * Release of E2fsprogs 1.22
361 2001-06-22 Theodore Tso <tytso@valinux.com>
363 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
364 descriptor so that adding a journal to a mounted
365 filesystem doesn't die. (Fixes a bug accidentally
366 introduced in e2fsprogs 1.21.)
368 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
369 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
370 fchflags without defining UF_NODUMP. (Addresses Debian
373 * flushb.c: Use platform independent method of defining the
374 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
375 since on newer glibc's BLKFLSBUF is defined there.
377 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
378 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
379 to support byte swapping even if we don't support the
380 conversion functions. (Fixes Debian bug #101686).
382 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
383 since the byte-swapping code all assumes the
384 ext2_dir_entry structure. (It's a question of whether or
385 not name_len should be byte-swapped or not, and whether
386 it's a 16 bit or 8 bit field.)
388 2001-06-15 Theodore Tso <tytso@valinux.com>
390 * Release of E2fsprogs 1.21
392 2001-06-15 Theodore Tso <tytso@valinux.com>
394 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
395 file which is generated and is therefore found in the
396 build directory, not source directory.
398 * ismounted.c (check_mntent_file): Use a test file in / to check
399 to see if the root filesystem is mounted read-only. This
400 protects against the case where /etc might not be on /, as
401 well as the case where /etc/mtab doesn't exist. (Both are
402 should-never happen scenarios, but you never know...)
404 2001-06-14 Theodore Tso <tytso@valinux.com>
406 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
407 Remove unneeded #pragma argsused, since the arguments are
410 2001-06-13 Theodore Tso <tytso@valinux.com>
412 * ext2_types.h.in: If linux/types.h has been defined, then don't
413 try to redefine the typedefs.
415 * Makefile.in (HFILES): Add ext2_types.h to the list of files
416 which should be installed.
418 * ismounted.c (check_mntent_file): Work around GNU hurd brain
419 damage. Addresses Debian bug #100304.
421 * Makefile.in: Limit some .o files from being included into the
422 library if --disable-debugfs, --disable-swapfs,
423 --disable-imager, or --disable-resizer are used.
425 2001-06-12 Theodore Tso <tytso@valinux.com>
427 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
428 function, and use the ext2fs_badblocks_* functions
431 2001-06-11 Theodore Tso <tytso@valinux.com>
433 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
434 ext2fs_mark_generic_bitmap and
435 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
436 functions. (This saves space and doesn't significantly
437 change the speed of e2fsck on a P-III.)
439 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
440 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
441 include the byte-swapping logic if ENABLE_SWAPFS is turned
442 on or if we're on a big-endian machine.
444 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
445 set EXT2_FLAG_SWAP_BYTES, instead of using
448 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
449 autoconf to determine whether or not return
450 EXT2_FLAG_SWAP_BYTES.
452 2001-06-10 Theodore Tso <tytso@valinux.com>
454 * Makefile.in: Remove the dependence on the libe2p library.
456 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
457 with direct usage of the ioctl/fchflags so that we don't
458 have to depend on the libe2p library.
460 2001-06-08 Theodore Tso <tytso@valinux.com>
462 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
463 when trying to find a 32-bit wide type.
465 * icount.c (insert_icount_el): Fix the code used to estimate the
466 size of the new icount array to be more intelligent, to
467 avoid reallocating the array too many times. Thanks to
468 Enrique Perez-Terron for pointing this out.
470 2001-06-02 Theodore Tso <tytso@valinux.com>
472 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
473 for a symlink to determine whether it is a fast symlink.
475 2001-06-01 Theodore Tso <tytso@valinux.com>
477 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
478 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
480 2001-05-25 Theodore Tso <tytso@valinux.com>
482 * Release of E2fsprogs 1.20
484 2001-05-25 Theodore Tso <tytso@valinux.com>
486 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
487 some to clean up Andreas's patches. Use strncpy instead
488 of strcpy to save the root's mountpoint. Clean up #ifdef
489 structure. Remove uneeded variable in testing/debug driver.
491 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
493 * ismounted.c: Add check for root device which doesn't depend on
494 /etc/fstab or /proc/mounts to be correct. Don't call
495 endmntent() before we are done with mnt struct.
497 2001-05-23 Theodore Tso <tytso@valinux.com>
499 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
502 2001-05-21 Theodore Tso <tytso@valinux.com>
504 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
505 make room for pre-existing usage of
506 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
507 the same codepoint as EXT2_BTREE_FL.
509 2001-05-20 Theodore Tso <tytso@valinux.com>
511 * ext2fs.h: #include <> instead of "" for ext2fs and et header
512 files, since they will be installed in /usr/include
514 2001-05-14 Theodore Tso <tytso@valinux.com>
516 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,

531 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
534 2001-05-05 Theodore Tso <tytso@valinux.com>
536 * fileio.c (ext2fs_file_read): Factored out common code and
537 cleaned up function. Fixed a bug where if there was an
538 error reading from the disk, the number of bytes read
539 wasn't reliably set. (Fixes Debian bug #79163)
540 (ext2fs_file_write): Factored out common code and made
541 function more efficient; if writing a full block, don't
542 bother to do a read-modify-write cycle.
544 2001-05-04 Theodore Tso <tytso@valinux.com>
546 * dirblock.c (ext2fs_read_dir_block): Check for an directory
547 record length which isn't a multiple four, and treat that
548 as an invalid. Scan the directory and return an error
549 (EXT2_ET_DIR_CORRUPTED) if the directory records are
551 (ext2fs_write_dir_block): If while byte-swapping the
552 directory block, if there's an error, abort and return
553 EXT2_ET_DIR_CORRUPTED.
555 2001-05-02 Theodore Tso <tytso@valinux.com>
557 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
558 image_header field in the ext2_filsys structure
560 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
561 * inode.c (ext2fs_read_inode):
562 * rw_bitmaps.c (read_bitmaps):
563 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
565 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
566 sure the full bitmap is saved.
568 2001-05-01 Theodore Tso <tytso@valinux.com>
570 * e2image.h (struct ext2_image_hdr): Add space for the device name
573 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
574 make sure the rec_len is a multiple of 4, to prevent
575 bus-errors on architectures which care about mis-aligned
578 2001-04-25 Theodore Tso <tytso@valinux.com>
580 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
581 query the device sizes using the BLKGETSIZE ioctl.
583 2001-04-16 Theodore Tso <tytso@valinux.com>
585 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
586 before checking /etc/mtab. The EXT2_MF_READONLY flag is
587 now set from the /etc/mtab options field for all
588 filesystems, not just the root filesystem. Add debugging
589 code to make it easier to test ext2fs_check_if_mounted().
591 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
592 check; return an error if there's an attempt to create a
593 journal less than 1024 filesystem blocks.
595 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
596 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
598 2001-02-20 Theodore Tso <tytso@valinux.com>
600 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
603 * tst_byteswap.c: New function to test the byteswap functions.
604 Add to regression test suite.
606 2001-02-08 Theodore Tso <tytso@valinux.com>
608 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
610 2001-02-07 Theodore Tso <tytso@valinux.com>
612 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
613 of s_first for external devices to always be 1, since
614 jsb->s_first is always relative to the start of the
615 journal superblock. Use htonl(1) when setting s_nr_users.
617 2001-01-17 Theodore Ts'o <tytso@valinux.com>
619 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
620 device number of the filesystem (instead of the journal)
621 was being dropped into s_journal_dev.
623 2001-01-15 Theodore Ts'o <tytso@valinux.com>
625 * initialize.c (ext2fs_initialize): Add support for initializing
626 the ext2 superblock for external journal devices. This
627 basically means we don't bother to allocate any block
630 * openfs.c (ext2fs_open): Only open external journal devices if
631 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
632 ext2fs_open. When opening such devices, don't try to read
633 the block group descriptors, since they're not there.
635 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
637 * mkjournal.c: Export a new function,
638 ext2fs_create_journal_superblock(), which allocates and
639 returns a buffer containing a journal superblock. This is
640 needed by mke2fs to create an external journal. Rewrote
641 ext2fs_add_journal_device() so that it no longer creates
642 the external journal, but rather adds a filesystem to an
643 existing external journal. It handles all of the UUID
646 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
647 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
648 Changed function prototype for ext2fs_add_journal_device().
650 2001-01-14 Theodore Ts'o <tytso@valinux.com>
652 * closefs.c (ext2fs_flush): Don't write out anything beyond the
653 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
656 2001-01-12 Theodore Ts'o <tytso@valinux.com>
658 * imager.c: Fix gcc -Wall complaints and a series of bugs where
659 retval wasn't set correctly. (Thanks to Andreas Dilger
660 for pointing this out.)
662 2001-01-11 <tytso@snap.thunk.org>
664 * flushb.c (ext2fs_sync_device): New function which centralizes
665 all of the places which might try to use the BLKFLSBUF
666 or FDFLUSH ioctls (and usually failing to define them
667 since the system header files don't usually do this for
668 us, and we're trying to avoid usage of kernel include
671 2001-01-10 <tytso@snap.thunk.org>
673 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
674 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
675 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
676 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
677 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
678 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
679 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
680 ext2_ino_t, to protect applications that attempt to
681 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
682 changes ino_t(!?). So we use ext2_ino_t to avoid an
683 unexpected ABI change.
685 2001-01-05 <tytso@snap.thunk.org>
687 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
688 we may overrun allocated memory in case of a corrupted
689 filesystem (or an e2fsck test case :-) when byte-swapping
692 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
694 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
695 complaints including a missing return 0 at the end of
696 ext2fs_add_journal_device.
698 2001-01-03 <tytso@snap.thunk.org>
700 * Makefile.in: Link in libe2p when creating libext2fs as a shared
701 library, since mkjournal.c now references fsetflags().
703 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
704 Dilger's changes (with fixups) to allow on-line creation
707 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
708 EXT2_FLAG_SUPER_ONLY, which the close routines to only
709 update the superblock, and not the group descriptors.
711 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
713 * ismounted.c: add ext2fs_check_mount_point() function, which will
714 optionally return the mount point of a device if mounted
716 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
718 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
719 ext2fs_add_journal_inode()
721 2001-01-01 <tytso@snap.thunk.org>
723 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
724 source (but not binary) compatibility of some users of the
725 ext2 library. They should just simply do a global search
726 and replace of struct ext2fs_sb with struct
727 ext2_super_block, and use their own private copy of
728 ext2_fs.h if they aren't already.
730 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
731 Replace use of ext2fs_sb with ext2_super_block.
733 2000-12-31 <tytso@snap.thunk.org>
735 * ext2fs.h: Cleaned up header file by removing definitions of
736 feature flags that might not have been defined in older
737 ext2 header files. Now that we're using our own
738 include/linux/ext2fs.h header file, this can never happen.
740 * jfs_dat.h: Removed old header file which is no longer needed.
742 2000-12-13 Theodore Ts'o <tytso@valinux.com>
744 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
745 by Andreas Dilger to update the filesystem revision to
748 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
751 2000-12-09 <tytso@snap.thunk.org>
753 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
754 ext2fs_add_journal_device): Add a new argument to the APIs
755 of these function, which is a flags word. This is used to
756 allow the creation of a V1 superblock for those folks who
757 are using ext3 0.3b in production. Note, the user-land
758 interface for getting at this flag won't be documented, as
759 the V1 superblock is deprecated.
761 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
762 which creates a V2 superblock instead of a V1 superblock.
764 2000-11-21 <tytso@snap.thunk.org>
766 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
767 out by Andreas Dilger.
769 2000-11-05 <tytso@snap.thunk.org>
771 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
772 ext2_fs.h, Makefile.in: New file that has routines that
773 save ext2fs metadata to a file.
775 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
777 * e2image.h: New file which defines the file format for the ext2
778 image file. (Saved copy of ext2 metadata to a file as a
779 saving throw against worst-case damage.)
781 2000-11-01 <tytso@snap.thunk.org>
783 * inode.c (ext2fs_flush_icache): Add new function
784 ext2fs_flush_icache() which flushes the internal inode
785 cache. Applications which modify the inode table blocks
786 directly must call this function.
788 2000-10-26 <tytso@snap.thunk.org>
790 * mkjournal.c: Add #include of netinet/in.h, since Solaris
791 requires it for ntohl().
793 * ext2_io.h (io_channel_write_byte): Add new interface to allow
794 callers to write specific byte ranges. This is an
795 optional interface, which not all IO channels may
798 * unix_io.c (unix_write_byte):
799 * test_io.c (test_write_byte): Add implementation of the
802 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
803 function which writes the primary superblock. If the IO
804 channel supports writing raw bytes directly, only fields
805 which were modified are written to the disk. This makes
806 it safe(r) to use utilities like tune2fs on a mounted
809 * freefs.c (ext2fs_free): Free the original superblock if it is
812 * openfs.c (ext2fs_open): Store a copy of the original superblock
815 * ext2fs.h: Add a field to store the original superblock in the
816 ext2 context structure.
818 2000-10-24 <tytso@snap.thunk.org>
820 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
821 don't need to use llseek).
823 2000-10-24 <tytso@valinux.com>
825 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
826 creating an ext3 journal on a filesystem.
828 2000-08-21 <tytso@valinux.com>
830 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
832 2000-08-22 <tytso@valinux.com>
834 * unix_io.c: Make massive changes to support a multiple block
835 writethrough cacheing.
837 * ext2_io.h: Added flags field to the io_channel structure.
839 2000-08-19 <tytso@valinux.com>
841 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
842 provides the function ext2fs_find_block_device(). This
843 function returns the pathname to a block device, given its
846 2000-07-13 <tytso@valinux.com>
848 * Release of E2fsprogs 1.19
850 2000-07-07 Theodore Ts'o <tytso@valinux.com>
852 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
853 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
854 list of filesystem flags supported by the library.
856 2000-07-04 Theodore Ts'o <tytso@valinux.com>
858 * ext2fs.h: Update to include latest journalling additions to the
861 * dll/jump.funcs: Add new jumptable entries for
862 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
863 ext2fs_badblocks_equal.
865 * tst_badblocks.c: Update test program to test
866 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
868 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
869 writes out bad blocks list to a file.
871 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
872 changes the callback function to take two additional
873 arguments; a private blind pointer supplied by the caller,
874 and pointer to a char * containing a pointer to the
877 * badblocks.c (ext2fs_badblocks_equal): Add new function which
878 returns true if two badblocks list are equal.
880 * Makefile.in: Remove explicit link of -lc in the shared library.
881 (It shouldn't be necessary, and is harmful in some cases).
883 2000-06-10 Theodore Ts'o <tytso@valinux.com>
885 * getsize.c (main): Add debugging code under #ifdef DEBUG
887 2000-05-27 Theodore Ts'o <tytso@valinux.com>
889 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
890 earlier, so that if there's an error reading it, we can
891 more cleanly back out of the operation.
893 2000-05-25 <tytso@snap.thunk.org>
895 * getsize.c (ext2fs_get_device_size): Use open64() instead of
896 open() if it exists. Under linux, manually define the
897 ioctl for BLKGETSIZE if it isn't already defined and it's
900 * unix_io.c (unix_open): Use open64() instead of open() if it
903 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
904 available (and prototypes are defined) use it in
905 preference to llseek.
907 * Makefile: Add hack dependency rule so that parallel makes work
910 2000-05-18 Theodore Ts'o <tytso@valinux.com>
912 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
914 2000-04-03 Theodore Ts'o <tytso@valinux.com>
916 * block.c: Readibility tweak in conditionals involving
919 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
920 how to define __s64 and __u64. Turn off "compression is
921 experimental" warning if the cpp macro
922 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
924 2000-02-11 <tytso@snap.thunk.org>
926 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
927 Conditionally include Compression as a supported type if
928 ENABLE_COMPRESSION (via --enable-compression) is turned on.
930 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
932 2000-02-08 <tytso@snap.thunk.org>
934 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
935 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
936 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
937 Change to return the previous state of the bit that is
938 being marked or unmarked. For speed optimization.
940 2000-02-02 Theodore Ts'o <tytso@valinux.com>
942 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
944 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
945 needed any more; we know it will always be i_generation.
946 Add support for swapping the high bits of the uid and gid.
948 1999-11-19 <tytso@valinux.com>
950 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
951 counts if the link was successful. Patch suggested by
954 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
955 the source directory.
957 1999-11-10 <tytso@valinux.com>
959 * Release of E2fsprogs 1.18
961 1999-11-08 <tytso@valinux.com>
963 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
964 since ext2fs_badblocks_list_free was moved to freefs.c.
966 * tst_badblocks.c: Use the newer badblocks API names. Add
967 duplicate blocks to the test inputs to test dealing with
968 adding blocks which are already in the badblocks list.
970 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
971 of the list, use a shortcut O(1) operations instead of an
972 O(n) operation. (Idea suggested by David Beattie.)
974 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
975 of badblocks_list_free(), to save a procedure call.
977 1999-10-26 <tytso@valinux.com>
979 * Release of E2fsprogs 1.17
981 1999-10-26 <tytso@valinux.com>
983 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
984 seem to handle ~0UL the same way as they used to.
986 1999-10-25 <tytso@valinux.com>
988 * nt_io.c (_OpenNtName): Open the device using
989 FILE_SYNCHRONOUS_IO_NONALERT instead of
990 FILE_SYNCHRONOUS_IO_ALERT
991 (nt_open): At the end of the device open routine, unlock
992 the drive but do not dismount it.
994 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
997 1999-10-22 <tytso@valinux.com>
999 * Release of E2fsprogs 1.16
1001 1999-10-22 <tytso@valinux.com>
1003 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1005 * link.c (ext2fs_link): This call now uses the low three bits of
1006 the flags parameter to pass the directory filetype
1007 information; it will set the directory entry FILETYPE
1008 information if the filesystem supports it.
1010 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1011 option is set, then create the '.' and '..' entries with
1012 the filetype set to EXT2_FT_DIR.
1014 1999-09-24 <tytso@valinux.com>
1016 * nt_io.c: New file which supports I/O under Windows NT.
1018 1999-09-07 <tytso@valinux.com>
1020 * ext2fs.h: Add new fields for journalling and define new
1021 feature bits used by newer filesystems: IMAGIC_INODES,
1022 HAS_JOURNAL, RECOVER.
1024 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1025 we update the inode block count and size files so that the
1026 block count field is updated correctly when we create an
1029 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1031 * Release of E2fsprogs 1.15
1033 1999-06-23 <tytso@valinux.com>
1035 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1036 kernels that use i_generation instead of i_version. Patch
1037 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1039 1999-06-21 <tytso@valinux.com>
1041 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1042 directory entry before calling the callback function.
1043 This should prevent some core dumps of insufficiently
1044 paranoid callback functions.
1046 1999-05-29 <tytso@rsts-11.mit.edu>
1048 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1050 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1051 that we don't handle writing yet (we do). Fixed bug where
1052 we weren't allocating a big enough buffer for ext2_bmap.
1054 1999-05-03 <tytso@rsts-11.mit.edu>
1056 * openfs.c (ext2fs_open): Check to make sure that the number of
1057 blocks per group is not zero --- if so, it must be a bad
1060 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1062 * Release of E2fsprogs 1.14
1064 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1066 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1067 the inode number is zero; if it's zero, return
1068 EXT2_ET_BAD_INODE_NUM.
1070 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1072 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1073 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1076 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1078 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1079 non-Linux case to use EINVAL by default, unless it isn't
1080 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1083 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1085 * Release of E2fsprogs 1.13
1087 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1089 * Makefile.in: Updated dependencies.
1091 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1093 * initialize.c (ext2fs_initialize): Make sure that we allocate
1094 enough inodes so that we can make a valid filesystem.
1096 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1098 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1100 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1101 function declaration.
1103 * dblist.c (make_dblist): Add safety check in case the dblist
1104 pointer passed in is null (in which case, assign it to
1105 fs->dblist). Fixed some signed/unsigned warnings.
1107 * bmap.c: Make addr_per_block be of type blk_t to avoid
1108 signed/unsigned warnings.
1110 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1111 function declaration.
1113 * get_pathname.c (get_pathname_proc): Use return value from
1114 ext2fs_get_mem, instead of checking if &gp->name is
1117 * dir_iterate.c (ext2fs_process_dir_block):
1118 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1119 from the function declaration.
1121 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1122 return the error directly instead of jumping to the
1123 cleanup routine, since we don't need to do any cleanup.
1125 * alloc_table.c (ext2fs_allocate_group_table): Make this
1126 function take a dgrp_t for its group argument.
1128 * ext2fs.h: Make dgrp_t an __u32 type, and make
1129 fs->desc_group_count be of type dgrp_t.
1131 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1133 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1134 than 10 blocks when we need to expand the size of the
1137 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1139 * Release of E2fsprogs 1.12
1141 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1143 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1144 appropriate for all of the block group copies, so that
1145 it's clear where the beginning of the filesystem is on the
1146 disk. (For when the partition table gets scrod.)
1148 * ext2fs.h: Change the name of the feature from
1149 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1150 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1152 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1154 * inode.c (get_next_blockgroup): Fix bug where if
1155 get_next_blockgroup() is called early because of a missing
1156 inode table in a block group, the current_inode counter
1157 wasn't incremented correctly.
1159 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1161 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1162 against a completely trashed bad block inode.
1164 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1166 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1167 the stride length hits a bad value, we retry the block
1168 allocation starting at the beginning of the block group.
1170 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1171 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1172 e2_blkcnt_t to avoid collision with LFS API.
1174 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1176 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1177 way that avoids overflows on disk sizes greater than 4GB.
1179 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1181 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1182 return type for comparison functions for qsort.
1184 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1187 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1189 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1192 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1193 evade a potential problem with glibc's header files trying
1194 to spike out linux/types.h.
1196 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1197 include the old size of the memory, which is needed for
1198 some braindamaged memory allocation systems that don't
1201 * badblocks.c (ext2fs_badblocks_list_add):
1202 bb_inode.c (clear_bad_block_proc):
1203 dblist.c (ext2fs_add_dir_block):
1204 icount.c (insert_icount_el):
1205 irel_ma.c (ima_put):
1206 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1207 pass the old size of the memory to be resized to
1208 ext2fs_resize_mem().
1210 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1212 * Makefile.in: Change to use new installation directory variables
1213 convention. Fix uninstall rules to take $(DESTDIR) into
1216 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1218 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1219 with 32 bit longs, then we need to manually define __s64
1220 and __u64, since the current kernel header files don't
1221 define these if __STRICT_ANSI__ is defined. This is a
1222 problem if we are compiling with full GCC warnings, since
1223 we do need 64 bit support.
1225 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1226 since we're not using ext2fs_move_blocks() and there
1227 is some question as to its usefulness in its current
1230 * bmap.c (block_bmap): Remove unused function.
1232 * bmove.c (process_block): Fix -Wall warning.
1234 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1236 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1237 contain the offset into the inode.i_blocks array when
1238 ref_block is zero. Since we haven't done a formal
1239 release of e2fsprogs since block_iterate2 was first
1240 introduced, I removed block_iterate2, and renamed
1241 block_iterate3 to be block_iterate2.
1243 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1244 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1245 use of block_iterate and block_iterate2 to
1246 block_iterate2 with the new prototype for the
1247 interator function. (using blkcnt_t forr blockcount)
1249 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1251 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1252 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1253 conditional defines of new features COMPAT_DIR_PREALLOC,
1254 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1255 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1256 the library to declare that we support COMPAT_DIR_PREALLOC,
1257 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1259 * fileio.c: Rename function ext2fs_file_llseek to be
1260 ext2fs_file_lseek, which is more accurate.
1262 * block.c: Add new function ext2fs_block_iterate3 which calls
1263 the iterator function with the blockcount argument of
1264 type blkcnt_t. This version of the function is
1265 allowed to handle large files; the other fucntions are
1268 * ext2fs.h: Add new type blkcnt_t
1270 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1272 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1273 field wasn't getting correctly incremented for sparse
1274 files when the indirect or doubly-indirect block
1275 specified in the inode was zero.
1277 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1279 * unlink.c (unlink_proc):
1280 * lookup.c (lookup_proc):
1281 * link.c (link_proc):
1282 * get_pathname.c (get_pathname_proc):
1283 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1284 from dirent->name_len, so it can be used for other
1287 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1288 and indicate that we have support for this incompatible
1291 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1293 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
1295 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1297 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
1298 number of directories when the block group information is
1301 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1303 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1304 inode table is missing so that we catch the case where the
1305 first block group is missing.
1307 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1310 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1312 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1314 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1316 * test_io.c (test_flush): Add a debugging printf when the flush
1319 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1320 read in, return right away.
1322 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1324 * bitops.h: Don't try to do i386 inline asm functions if the
1327 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1328 instead of linux/types.h, and e2_bitops.h instead of
1331 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1334 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1336 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1337 so that we don't need to call get_next_blockgroup() the
1338 first time around. Saves a bit of time, and prevents us
1339 from needing to assign -1 to current_group (which is an
1342 * icount.c (insert_icount_el): Cast the estimated number of inodes
1343 from a float to an ino_t.
1345 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
1346 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1347 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

1355 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1356 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
1357 defined, then assume all of the
1358 ext2-specific header files are in a flat directory.
1360 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1361 all assignments from void * to be compatible with C++.
1363 Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1365 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
1366 make sure the contents of the disk are flushed to disk.
1368 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1371 avoid C++ namespace clash.
1373 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
1374 avoid C++ namespace clash.
1376 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,

1379 unlink.c: Change private to be priv_data (to avoid C++
1382 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1384 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1385 paranoid about validating the directory counts from the
1386 block group information.
1388 * all files: Don't include stdlib.h anymore; include it in
1389 ext2_fs.h, since that file requires stdlib.h
1391 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1393 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1394 bitmap is loaded, and return an error if it is not.
1395 (expand_dir_proc): Only use ext2fs_write_dir_block when
1396 writing a directory block, not when writing out a fresh

1423 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1425 * [all files, basically]: Added definition of ext2fs_get_mem,
1426 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and

1470 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1472 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H

1481 Mon Sep 15 11:45:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1483 * inode.c (ext2fs_check_directory): Add support for the callback
1484 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
1486 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1488 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
1489 padding of the bitmap to be all one's.
1491 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
1493 * llseek.c: Added missing semicolon to glibc fixup declaration of

1510 * io.h: Change the prototype of ext2fs_llseek() to use int's
1511 instead of unsigned int's.
1513 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1514 to make life easer for GNU Libc 2.
1516 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1517 filesystem has its bitmaps stored as 32-bit words with bit
1518 0 as the LSB of each word. Thus a bitmap with only bit 0
1519 set would be, as a string of bytes, 00 00 00 01 00 ... To
1520 cope with this, we byte-reverse each word of a bitmap if
1521 we have a big-endian filesystem, that is, if we are *not*
1522 byte-swapping other word-sized numbers.

1591 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1593 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1594 is zero, then return EXT2_IO_LLSEEK_FAILED.
1596 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1598 * Release of E2fsprogs 1.11
1600 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1602 * dblist.c (ext2fs_dblist_count): Added new function which returns
1603 the number of directory blocks in dblist.
1605 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1607 * unix_io.c (unix_flush): Make the io_channel flush function do a
1608 fsync to flush the kernel buffers to disk.
1610 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1612 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1613 current inode number wasn't being set by the
1614 goto_blockgroup function.
1616 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1618 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1619 of blocks which need to be moved, and moves those blocks
1620 to another location in the filesystem.
1622 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1623 bitmap, make sure all of the new parts of the bitmap are
1626 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1628 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1629 wasn't being returned to the caller.
1631 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1632 ext2fs_allocate_group_table() which sets the group tables
1633 for a particular block group. The relevant code was
1634 factored out of ext2fs_allocate_tables().
1636 * dblist.c (make_dblist): Adjust the initial size of the directory
1637 block list to be a bit more realistic (ten plus twice the
1638 number of directories in the filesystem).
1640 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1642 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1643 ext2fs_badblocks_list_test would test the list (and exceed
1644 array boundaries) if there were no bad blocks on the bad
1645 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1647 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1649 * Release of E2fsprogs version 1.10
1651 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1653 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1654 inode and block bitmaps based on the RAID 0 stride
1655 parameter (which is passed by mke2fs).
1657 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1658 mke2fs to communicate the stride length to
1659 ext2fs_allocate_tables()
1661 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1663 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1664 systems. (We can't assume that the new filesystem types
1667 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1669 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1670 allocate the inode and block bitmaps inside block group at
1673 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1675 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1676 filesystem has no free blocks, ext2fs_new_block would loop

1691 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1692 badblocks structure.
1694 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1698 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1700 (unix_close, test_close): Decrement the refcount and only
1701 close the io_channel if the refcount goes to 0.
1703 * io.h: Add refcount to the io_channel structure. Add new macro
1704 interface io_channel_bumpcount() to bump the refcount.
1706 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1708 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1709 cache in the filesystem handle, instead of the inode cache
1710 in a static variable.
1712 * freefs.c: Added static function to free the inode cache (called by
1715 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1717 * ext2fs.h: Added pointer to the inode_cache structure.
1719 * block.c (block_iterate_ind, block_iterate_dind,
1720 block_iterate_tind): If there are holes in the indirect,
1721 doubly indirect, or triply indirect blocks, increment the
1722 block count field automatically.
1724 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1726 * Release of E2fsprogs version 1.09
1728 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1730 * version.c (ext2fs_parse_version_string): Check the passed in
1731 version string (instead of the hard-coded one).
1733 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1734 greater filesystem size, clamp it to prevent allocating a
1735 block or inode bitmap beyond the filesystem.
1737 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1738 overhead calculation was accidentally removed.
1740 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1742 * Release of E2fsprogs version 1.08
1744 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1746 * dblist.c (ext2fs_set_dir_block): New function which sets the
1747 block of a dblist entry, given the directory inode and
1750 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1752 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1753 inode bitmaps at staggered locations across the block
1754 groups, to avoid concentrating the bitmaps on a small
1755 number of disks when using striped RAID arrays.
1757 * initialize.c (ext2fs_initialize): By default, choose the maximum
1758 possible number of blocks per group (based on the size of
1759 the bitmaps in the blocksize).
1761 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1763 * initialize.c (ext2fs_initialize): Add support for
1764 EXT2_COMPAT_SPARSE_SUPER feature.
1766 * closefs.c (ext2fs_bg_has_super): New function to determine
1767 whether or a particular block group should have a
1768 superblock and block group descriptor. Used for the
1769 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1770 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1771 or not the superblock should be written out for the block
1774 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1775 for sparse duplicate superblocks.
1777 * version.c (ext2fs_get_library_version): New function which
1778 returns the library version.
1780 * version.c (ext2fs_parse_version_string): New function which
1781 parses a version string and returns a version number,
1782 so application programs can compare version numbers as
1785 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1787 * icount.c (ext2fs_create_icount): Change function so that it also
1788 takes a new argument which contains a "hint" icount
1789 structure. This "hint" icount allows the create function
1790 to set up the sorted list in advance. This reduces
1791 significantly the amount of data moving needed to insert
1792 these inodes into the list later.
1794 * icount.c (ext2fs_icount_validate): New function which validates
1795 that the icount structure's rep invariant.
1797 * icount.c (get_icount_el): Completely revamped implementation
1798 to subsume put_icount_el(). Put_icount_el() used to
1799 use an O(N) implementation to insert in the middle
1800 of the icount list. It now uses a O(ln N) to search
1801 for where the icount should be inserted, and then uses
1802 a memcpy to move the list down (instead of a for loop).
1804 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1805 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1806 to see if the inode is within bounds; if it isn't, return
1809 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1810 when a bad inode number is passed to test_generic_bitmap
1811 to be EXT2FS_TEST_ERROR instead of the wrong
1812 EXT2FS_UNMARK_ERROR.
1814 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1816 * Release of E2fsprogs version 1.07
1818 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1820 * Makefile.in (ELF_VERSION): Change version to be 2.2
1822 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1824 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1825 ext2fs_fast_test_block_bitmap_range().
1827 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1828 ext2fs_test_block_bitmap_range: New inline functions which
1829 test to see whether a contiguous range of blocks is
1832 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1834 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1835 use ext2fs_badblocks_* instead of badblocks_*
1837 * bb_compat.c: New file which translates between old badblocks_*()
1838 names to ext2fs_badblocks_*()
1840 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1841 link.c (since e2fsck doesn't use ext2fs_unlink()).
1843 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1844 bitmap resizing routine moved from bitmaps.c, since e2fsck
1845 doesn't need to use this function.
1847 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1848 since e2fsck only needs ext2fs_lookup.
1850 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1852 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1853 already set; this is needed so that programs like dump
1854 which use the inode scan functions will deal with
1855 filesystems that have bad blocks in the inode table.
1857 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1859 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1860 Moved to ext2fsP.h, since it doesn't need to be part of
1861 the public interface.
1863 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1865 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1867 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1868 directory block list abstraction. (Code moved from
1871 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1872 to inode.c (since no one else should be peeking inside it!)
1874 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1876 * openfs.c (ext2fs_open): Check the feature set in the ext2
1877 superblock, and refuse to open filesystems if they contain
1878 incompatible features. (Can be overriden with the
1881 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1883 * block.c (ext2fs_block_iterate2): Added new function
1884 ext2fs_block_iterate2 which changes the function
1885 signature of the callback function to include the
1886 referencing block and offset.
1888 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1889 ext2fs_inode_scan_goto_blockgroup which allows an
1890 application to jump to a particular block group while
1891 doing an inode scan.
1893 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1895 * dirblock.c: Include string.h, since we use memcpy().
1897 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1899 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1900 a long not an int; this doesn't matter on i386 machines,
1901 but it does on Alpha's.
1903 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1905 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1906 table pointer is NULL, then return an error indicating
1907 that the inode table is missing.
1908 (get_next_blockgroup, get_next_blocks,
1909 ext2fs_get_next_inode): Don't treat a missing inode table
1910 as permanent error. Return MISSING_INODE_TABLE, but as an
1911 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1913 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1914 ext2fs_write_inode_bitmap): If the inode or block bitmap
1915 block is zero, then don't write out the inode or block
1916 bitmap. The idea here is to avoid stomping on the
1918 (read_bitmaps): If the inode or block bitmap block is
1919 zero, then fill in that portion of the inode or block
1920 bitmap with all zeros.
1922 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1923 blocks in inode table when the inode table size is
1924 non-standard (and can therefore span blocks).
1926 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1928 * alloc.c (ext2fs_new_block): Fix fencepost error in
1929 ext2fs_new_block; make sure we don't try to allocate the
1930 first block beyond the end of the filesystem.
1932 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1934 * inode.c (check_for_inode_bad_blocks): New function called by
1935 get_next_blocks() to avoid reading in bad blocks marked in
1936 fs->badblocks. Inodes located in bad blocks are returned
1937 by ext2fs_get_next_inode() returns the error code
1938 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1940 * alloc_tables.c (ext2fs_allocate_tables): New function which
1941 performs the part of mke2fs's job of allocating the
1944 * test_io.c (test_close): IO manager which is used for testing
1947 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1949 * inode.c (ext2fs_get_next_inode): Separate out the function of
1950 setting up for a new block group to get_next_blockgroup().
1951 Separate out the function of reading in blocks of the
1952 inode table to get_next_blocks().
1954 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1956 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1957 blocks to the badblock list in sorted order. This allows
1958 badblocks_list_test to be coded using a binary search for
1961 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1963 * Release of E2fsprogs version 1.06
1965 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1967 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1968 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1971 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1972 set, then only write out the master superblock.
1974 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1976 * block.c (ext2fs_block_iterate): Fixed bug which caused
1977 block_iterate to fail to handle HURD created filesystems;
1978 it tested the inode translator field before the inode was
1981 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1983 * initialize.c (ext2fs_initialize): Make sure the description for
1984 the inode bitmap is set correctly.
1986 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
1988 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1990 * Release of E2fsprogs version 1.05
1992 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1994 * initialize.c: Override the kernel's idea of default
1995 checkinterval from 0 (never) to 180 days.

2004 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2005 for shortcut function fs->read_inode() and fs->write_inode().
2006 Added inode_cache to reduce CPU time spent in doing
2009 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
2012 * namei.c (ext2fs_follow_link): New function.
2013 (ext2fs_namei): Extended to have support for chasing
2014 symbolic links. ext2fs_namei() still returns an inode
2015 which is a symbolic link. Symbolic links are only chased
2016 while resolving the containing directory. To chase
2017 symbolic links of the final result, use
2018 ext2fs_follow_link().
2020 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2022 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2024 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2025 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

2029 * initialize.c (ext2fs_initialize): On systems where the byte
2030 order is not i386 compatible, set the swap_byte flag.
2032 * inode.c (inocpy_with_swap): Check to see if inode contains a
2033 fast symlink before swapping the inode block fields. This
2034 required adding a new argument to inocpy_with_swap to
2035 determine whether the mode field is in host order or not.
2037 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2039 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2040 the sparc, if EXT2_STD_BITOPS set, use the standard
2041 i386-compatible bitmask operations, instead on the
2042 non-standard native bitmask operators.
2044 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2046 * block.c (ext2fs_block_iterate): Cause block iterator to return
2047 the HURD translator block (along with everything else).
2048 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2049 iterator, then don't return any meta data blocks
2050 (including the HURD translator).
2052 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2054 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2056 * uuid.c: New file, containing UUID utility functions.
2058 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2060 * ext2fs.h: Add a definition of the "real" ext2 superblock.
2062 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2064 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
2066 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2068 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2069 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2070 that's a basic value that must be correct for the rest of
2071 the library to work.
2073 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2076 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2078 * Release of E2fsprogs version 1.04

2082 * Release of E2fsprogs version 1.03
2084 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
2086 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
2087 Change the m68k bit numbering for bitmasks to match with
2088 the bit numbering used by all other ext2 implementations.
2090 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
2092 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

2123 * rw_bitops.c (ext2fs_write_block_bitmap):
2124 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2125 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2126 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2127 to avoid conflicts with with kernel include files. Also
2128 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2131 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2133 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
2135 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
2136 s_def_resuid and s_def_resgid for backwards compatibility.
2138 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
2140 * bitops.h: Added #ifdef's for Sparc.
2142 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
2144 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
2147 * closefs.c: #include <string.h> to pick up memset() declaration
2149 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
2151 * Makefile.in: Added support for BSD shared libraries.
2153 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2156 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2158 * unix_io.c (unix_open): Add a double check; if the passed in name
2159 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2161 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2163 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

2170 * getsize.c (ext2fs_get_device_size): Add support for reading the
2171 partition size from a BSD disk label.
2173 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2175 * getsize.c (ext2fs_get_device_size): New function that determins
2176 the size of a device. Used by mke2fs and e2fsck.

2185 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2186 Move these functions to freefs.c.
2188 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2189 descriptors shadow memory to keep purify quiet. (This
2190 also has the nice benefit that the unused portion of the
2191 shadow descriptors are zeroed out.)
2193 * dirblock.c (ext2fs_write_dir_block): We need to use
2194 dirent->rec_len *before* it's byteswapped to find the
2195 location of the next directory structure!
2197 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2198 cause ext2fs_new_inode to loop infinitely if we're trying
2199 to allocate an inode in group #0 and there are no free
2200 inodes at all in the system.
2202 * closefs.c: #include <errno.h> if it exists.
2204 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2206 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2212 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
2213 installation directories correctly.
2215 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
2217 * namei.c (process_dir_block):
2218 * mkdir.c (ext2fs_mkdir):
2219 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
2220 to read/write the directory block.
2222 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
2223 file containing functions for reading and writing
2224 directory blocks (byte swapping if necesssary)
2226 * block.c (block_iterate_ind, block_iterate_dind,
2227 block_iterate_tind): Byte swap the block addresses if
2228 EXT2_SWAP_BYTES is set (and swap them back before writing
2231 * inode.c (inocpy_with_swap): New function.
2232 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
2233 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2235 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2236 the superblock and group descriptors before writing it out.
2238 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2239 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2240 and group descriptors.
2242 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2243 to desp ext2 filesystem structures.
2245 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2246 supplied by Pete A. Zaitcev so that the C language
2247 versions of these functions are more portable. They will
2248 now work on both little and big endian systems, and the
2249 assumption that 32-bit integers are used is gone.
2251 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2252 doing byte swapping.
2254 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2255 byte swapping should take place.
2257 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
2259 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
2260 ext2fs_compare_inode_bitmap_end): Added new file
2261 containing routines to compare bitmaps.
2263 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
2264 Added new error codes.
2266 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
2268 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2269 if the magic number is correct, it will be allocated.
2271 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2273 * block.c (block_iterate_ind, block_iterate_dind,
2274 block_iterate_tind): Don't recompute block_nr each loop;
2275 just increment it! Factor check of BLOCK_FLAG_APPEND out
2276 of the loop. Factor mask of BLOCK_CHANGED into changed
2277 variable out of the loop. (block_iterate_ind, in
2278 particular, gets called a lot, so every little
2279 optimization helps.)
2281 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2283 * block.c (block_iterate_ind, block_iterate_dind,
2284 block_iterate_tind): Precompute limit of loop to speed up
2285 block_iterate_ind and company.
2287 * bitops.h (ext2fs_fast_mark_block_bitmap,
2288 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
2289 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2290 ext2fs_fast_test_inode_bitmap): Add fast version of these
2291 functions, which don't do range checking.
2293 * bitops.h (ext2fs_get_block_bitmap_start,
2294 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2295 ext2fs_get_inode_bitmap_end): Add new accessor functions
2296 which return the start and end points of the bitmaps.
2298 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2300 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2301 instead of llseek. The errno if the offset is too large
2302 and lseek is not supported should be EINVAL, not -EINVAL.
2304 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2306 * Makefile.in: Added support for ELF shared libraries.
2307 Fixed typos in the compilation rules.
2308 (distclean): Added Makefile.
2310 * llseek.c (llseek): New function, if llseek() does not exist in the
2312 (ext2_llseek): Changed to call llseek().
2314 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2316 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
2318 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2320 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2322 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2323 the S_*, which are normally defined in <sys/stat.h>. This
2324 allows us to compile e2fsprogs on a non-Linux system,
2325 which may have a different value for S_IFDIR.
2327 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2329 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2330 this is a user-mode application!
2332 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2334 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2335 __linux__ so that non-linux systems won't see it.
2337 * alloc.c: Include <errno.h> if possible.
2338 * badblocks.c: Ditto.
2339 * bb_inode.c: Ditto.
2342 * expanddir.c: Ditto.
2343 * get_pathname.c: Ditto.
2344 * initialize.c: Ditto.
2351 * rw_bitmaps.c: Ditto.
2354 * Makefile.in: Rewritten to conform to GNU coding standards and
2355 support separate compilation directories.
2357 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2359 * initialize.c (ext2fs_initialize): Don't allow more than one
2360 bitmaps's worth of inodes in a group.
2362 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2364 * llseek.c (ext2_llseek): Added error checking to the llseek()
2365 compat code to protect against overflow. This only
2366 applies to 1.0 and early 1.1 kernels, which don't support
2367 the llseek() system call.
2369 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2371 * unix_io.c (unix_open): Initialize the read_error and write_error
2372 io_channel pointers to be null.
2374 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2375 found, clear it but don't try to update the filesystem
2376 accounting information, since that's hopeless anyway.
2378 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2379 bloblock_iterate_tind): Check to see if the indirect blocks are
2380 valid before trying to read them.
2382 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
2383 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2385 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2386 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2387 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2388 illegal block or inode number is passed in, return instead
2389 of trying to test, set, or clear the bit.
2391 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2393 * Makefile: Added a dummy install target in case shared libraries
2396 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2398 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
2399 the real last block of the bitmap should be calculated.
2401 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
2403 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
2404 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
2405 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
2406 ext2fs_free_block_bitmap): Add magic number checking for
2407 the inode and block bitmaps.
2409 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2410 magic number for a block bitmap instead of an inode bitmap.
2412 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
2413 magic number checking for the inode_scan structure.
2415 * badblocks.c (badblocks_list_free, badblocks_list_add,
2416 badblocks_list_test, badblocks_list_iterate_begin,
2417 badblocks_list_iterate, badblocks_list_iterate_end): Add
2418 magic number checking for the badblocks_list and
2419 badblocks_iterate structures.
2421 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
2422 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
2423 unix_write_blk, unix_flush): Add magic number checking
2424 both for io_channel structure and unix_private_data
2427 * openfs.c (ext2fs_open): Add check for io_manager structure's
2430 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2431 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2432 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2433 * read_bb.c (ext2fs_read_bb_inode):
2434 * read_bb_file.c (ext2fs_read_bb_FILE):
2435 * newdir.c (ext2fs_new_dir_block):
2436 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
2437 * link.c (ext2fs_link, ext2fs_unlink):
2438 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

2443 * block.c (ext2fs_block_iterate):
2444 * bitmaps.c (ext2fs_allocate_inode_bitmap,
2445 ext2fs_allocate_block_bitmap):
2446 * bb_inode.c (ext2fs_update_bb_inode):
2447 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
2448 * check_desc.c (ext2fs_check_desc):
2449 * closefs.c (ext2fs_close, ext2fs_flush):
2450 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2455 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2456 openfs.c into its own file.
2458 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2459 structure magic numbers.
2461 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2462 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2463 someone uses the -b option to specify the use of the backup
2464 superblock --- this usually means that the main superblock is
2468 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2469 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2470 revision level to the superblock.
2472 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2479 * initialize.c: Completely revamped the inode and block bitmap
2480 structures, so that they can be better chance of being extensible
2481 in a shared library. They are now their own type, instead of
2482 being a char *. Also, the function signatures of
2483 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2484 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2485 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2486 changed to eliminate the ext2_filsys argument, since it is no
2489 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2491 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2492 system call if available.
2494 * llseek.c: new file. This is the stub calling the llseek system
2495 call which allows supports for 2GB+ file systems.
2497 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2498 the creator operating system.
2500 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2502 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2503 the group descriptor statistics in addition to everything else.
2504 This relieves mke2fs of the responsibility of doing it.
2506 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2507 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2508 not the generic C function equivalents should be included or not.
2510 * openfs.c (ext2fs_open): If a superblock is specified, then use
2511 the backup group descriptors that go along with this superblock,
2512 instead of using the primary group descriptors. This allows
2513 e2fsck to recover filesystems where the primary group descriptors
