1 2002-08-13 <tytso@snap.thunk.org>
3 * Makefile.in: Move dupfs.o and test_io.o from the
4 needed-by-debugfs object list to the needed-by-resizer
5 object list. Fixes compile problem if the system is built
6 with only --disable-debugfs.
8 2002-07-29 Theodore Ts'o <tytso@mit.edu>
10 * link.c (ext2fs_link): When adding a new link to a directory,
13 2002-07-23 Theodore Ts'o <tytso@mit.edu>
15 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
16 calculations for names > 32 characters to be completely
17 bogus. Changed MD4 calculation to match what is currently
18 being used in the CVS gkernel tree.
20 2002-07-19 Theodore Ts'o <tytso@mit.edu>
22 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
23 superblock definition.
25 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
26 create a set of u32_list functions.
28 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
29 since that's required by the directory indexing code.
31 2002-07-14 Theodore Ts'o <tytso@mit.edu>
33 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
34 using a C++ reserved word.
36 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
37 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
38 old version of glibc (built against 2.2 headers) will
39 interact badly with the workaround to actually cause more
40 problems. I hate it when the glibc folks think they're
41 being smarter than the kernel....
43 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
45 * ext2_fs.h: Add superblock field for reserved group descriptors.
47 2002-06-28 Theodore Ts'o <tytso@mit.edu>
49 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
50 ext2fs_cpu_to_{l,b}e{32,16}
52 2002-06-27 Theodore Ts'o <tytso@mit.edu>
54 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
55 Add appropriate fallbacks in this case.
57 2002-06-26 Theodore Ts'o <tytso@mit.edu>
59 * dirhash.c (ext2fs_dirhash): Change function signature to support
60 a hash seed, and to return the minor hash (for 64-bit hash
61 support). Add support for the half MD4, half MD4 with
62 seed, and half MD4 with seed and 64 bits.
64 2002-06-15 Theodore Ts'o <tytso@mit.edu>
66 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
68 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
70 * ext2_fs.h: Add macros for maximum block/inode counts:
71 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
72 and EXT2_MAX_INODES_PER_GROUP.
74 * openfs.c (ext2fs_open): Check that the number of blocks in a group
75 is less than 2^16, otherwise we need an INCOMPAT flag (not
76 in existence yet, if ever) to open such a filesystem.
78 * initialize.c (ext2fs_initialize): Limit the number of blocks and
79 inodes in a group to less than 2^16.
81 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
83 * ext2_fs.h: Further minor cleanups of the header. Consolidate
84 some checks for __KERNEL__ into one place.
86 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
88 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
89 the EXT2_SB() macro instead. Remove kernel function
90 prototypes also. This matches the 2.5 kernel, and
91 is also cleaner for other reasons. Whitespace cleanup.
93 2002-05-21 Theodore Ts'o <tytso@mit.edu>
95 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
97 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
99 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
101 * initialize.c (ext2fs_initialize): Remove assumption that
102 blocksizes are always <= 4k.
104 2002-05-11 Theodore Ts'o <tytso@mit.edu>
106 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
107 silently if inode pointer is NULL (and ext2fs_bmap is
108 expected to read the inode itself).
110 2002-04-27 Theodore Ts'o <tytso@mit.edu>
112 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
113 file we are checking is a block device file before looking
114 at st_rdev, since it's not valid for normal files.
115 (is_swap_device): Move so that it is outside the
116 HAVE_MNTENT_H, so that it is always built.
118 2002-03-11 Theodore Tso <tytso@mit.edu>
120 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
121 functions which take an extra flags argument. The flag
122 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
123 field is byte swampped on big-endian machines, since in
124 the V2 structure, name_len is a char field which is
125 doesn't need to be byte swapped --- except if an
126 old-style kernel had byte-swapped the name_len field
127 as part of the V1 structure.
129 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
131 * dirhash.c (ext2fs_dirhash): New function which calculates the
132 hash for a filename in an indexed directory.
134 2002-03-08 Theodore Tso <tytso@mit.edu>
136 * Release of E2fsprogs 1.27
138 2002-03-07 Theodore Tso <tytso@mit.edu>
140 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
142 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
143 tst_byteswap.c: Fix gcc -Wall complaints
145 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
146 (From Philipp Thomas <pthomas@suse.de>)
148 2002-02-25 Theodore Tso <tytso@mit.edu>
150 * ext2_fs.h: Add structure definitions for the directory indexing
153 2002-02-23 Theodore Tso <tytso@mit.edu>
155 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
156 it doesn't break things on mis32, sparc32, and alpha
159 2002-02-21 Theodore Tso <tytso@mit.edu>
161 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
162 we were missing an fclose().
164 2002-02-20 Theodore Tso <tytso@mit.edu>
166 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
167 abstraction interface which exports an ext2 inode.
169 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
170 as a public interface. Change void * to const void * in
171 ext2fs_file_write's interface.
173 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
174 conditional; save a few bytes.
176 2002-02-12 Theodore Tso <tytso@mit.edu>
178 * Makefile.in (tst_badblocks): Add some extra .o files when
179 linking the debugging program tst_badblocks which are
180 needed if we aren't compiling with inline functions enable.
182 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
183 define away __inline__ since it may not be supported.
185 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
186 stripped down jbd_debug that doesn't use variadic
187 arguments. This will cause warnings under AIX, but things
190 2002-02-03 Theodore Tso <tytso@thunk.org>
192 * Release of E2fsprogs 1.26
194 2002-02-03 Theodore Tso <tytso@mit.edu>
196 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
197 so that the number of directories in use is adjusted
200 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
201 which optionally will modify the number of directories
204 2002-01-03 Theodore Tso <tytso@mit.edu>
206 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
207 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
208 which will return deleted directory entries.
209 ext2fs_dir_iterate2 takes a new callback function which
210 is identical with the one used by
211 ext2fs_dblist_dir_iterate(). If the directory entry is
212 deleted, the callback function will be called with the
213 entry paraemter set to DIRENT_DELETED_FILE.
215 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
216 ext2fs_block_alloc_stats): New functions which update
217 block/inode allocation statistics in the bitmaps, block
218 group descriptors, and superblock.
220 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
221 expanddir.c (expand_dir_proc), bb_inode.c
222 (clear_bad_block_proc, set_bad_block_proc,
223 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
224 Update to use new block/inode allocation statistics.
226 2001-12-24 Theodore Tso <tytso@mit.edu>
228 * ismounted.c (is_swap_device): New function used by
229 ext2fs_check_if_mounted and ext2fs_check_mount_point which
230 determines whether or not the specified device is a swap
231 device by using /proc/swaps. More bulletproofing for
232 idiotic/careless system administrators!
234 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
235 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
236 field to struct_ext2_filsys, umask. This field is
237 initialize to 022, and affects ext2fs_mkdir in the obvious
238 way. (In the future umask should also affect new file
239 creation routines, but the fileio functions don't
240 currently support this yes.)
242 * ismounted.c (check_mntent_file): Stat all of the entries in
243 /etc/mtab and/or /proc/mounts in order to catch dim-witted
244 system administrators who might have created alias
247 2001-12-23 Theodore Tso <tytso@mit.edu>
249 * Makefile.in, jfs_user.h: Move linux/jbd.h to
250 ext2fs/kernel-jbd.h, to avoid using the system header
251 file version of hbd.h when using diet glibc (since it
252 forcibly adds /usr/include to the beginning of the
253 include search path.)
255 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
256 include/linux directory.
258 2001-12-16 Theodore Tso <tytso@mit.edu>
260 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
261 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
262 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
264 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
267 2001-12-03 Theodore Tso <tytso@mit.edu>
269 * unix_io.c (unix_open): Make sure the ulimit workaround works
270 regardless of the version of glibc which is used to
273 2001-11-26 Theodore Tso <tytso@mit.edu>
275 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
276 trying to unset the filesize limit if at all possible,
277 if a block device is getting opened. (The filesize limit
278 shouldn't be applied against writes to a block device, but
279 starting in 2.4.10, the kernel is doing this.)
281 2001-11-05 Theodore Tso <tytso@mit.edu>
283 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
284 file on adding a journal to an already-mounted filesystem,
285 try to clear the ext2 file attributes on an already
286 existing .journal file so that we don't fail if on a
287 partially added journal to the filesystem.
289 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
290 which signals that a particular inode should not have the
291 last bits of data (the "tail") be merged with another
292 file. This is necessary to keep LILO happy.
294 2001-09-20 Theodore Tso <tytso@thunk.org>
296 * Release of E2fsprogs 1.25
298 2001-09-16 Theodore Tso <tytso@mit.edu>
300 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
301 which was breaking the build on the Hurd. (Addresses
304 2001-09-13 Theodore Ts'o <tytso@mit.edu>
306 * ismounted.c (check_mntent_file): We now validate the entry in
307 /etc/mtab to make sure the filesystem is really mounted,
308 since some broken distributions (read: Slackware) have
309 buggy boot scripts that don't initialize /etc/mtab before
310 checking non-root filesystems. (Slackware also doesn't
311 check the root filesystem separately, and reboot if the
312 root filesystem had changes applied to it, which is
313 dangerous and broken.)
315 2001-09-02 Theodore Tso <tytso@thunk.org>
317 * Release of E2fsprogs 1.24a
319 2001-08-30 Theodore Tso <tytso@thunk.org>
321 * Release of E2fsprogs 1.24
323 2001-08-30 Theodore Tso <tytso@valinux.com>
325 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
326 changes, since the ioctl number has been reused by another
329 2001-08-15 Theodore Tso <tytso@valinux.com>
331 * Release of E2fsprogs 1.23
333 2001-08-05 Theodore Tso <tytso@valinux.com>
335 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
336 version of the bitmap test routines to speed up these
337 routines. (At some point I may want to make these
338 routines use the find_first_bit functions, but that will
339 add a lot of complexity since it means that these
340 functions will have to break the bitmap abstraction
341 boundary. It's not clear it's worth it.)
343 * mkjournal.c (mkjournal_proc): Remember the last block allocated
344 to speed up ext2fs_new_block().
346 2001-07-29 Theodore Tso <tytso@valinux.com>
348 * finddev.c (scan_dir): Fix memory leak; we weren't calling
349 closedir() when exiting the function in all cases.
351 2001-07-27 Theodore Tso <tytso@valinux.com>
353 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
354 block usable in the journal for external journals to be 2
355 or 3, depending on the blocksize, so that the existing
356 kernel code does the right thing.
358 * getsize.c (ext2fs_get_device_size): Add support for the
359 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
360 from Ben LaHaise, but it's likely this interface won't
363 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
364 when writing the journal superblock, too. (Oops! Needed
365 to make 1k filesystems with external journal to work.)
367 2001-07-26 Theodore Tso <tytso@valinux.com>
369 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
370 to find the journal superblock if the blocksize is 1024.
372 2001-07-21 Theodore Tso <tytso@valinux.com>
374 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
376 2001-07-20 Theodore Tso <tytso@valinux.com>
378 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
379 attribute block, set the filesystem changed bit.
381 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
382 Comment out these functions since we're not using them.
384 2001-07-10 Theodore Tso <tytso@valinux.com>
386 * closefs.c (write_primary_superblock): After writing changes to
387 the primary superblock, update the original superblock
388 copy so we don't have to re-write those changes in the
390 (ext2fs_flush): Clear the superblock dirty flag after
391 we've flushed out changes to disk.
393 2001-07-07 Theodore Tso <tytso@valinux.com>
395 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
396 to avoid register conflicts when compiling in PIC mode.
398 2001-07-04 Theodore Tso <tytso@valinux.com>
400 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
401 Add new functions (C and in i386 assembler) which quickly
402 find bits set in a bitmask.
404 2001-06-23 Theodore Tso <tytso@valinux.com>
406 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
407 ext2_ext_attr.h and ext_attr.c for extended attributes
410 * Release of E2fsprogs 1.22
412 2001-06-22 Theodore Tso <tytso@valinux.com>
414 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
415 descriptor so that adding a journal to a mounted
416 filesystem doesn't die. (Fixes a bug accidentally
417 introduced in e2fsprogs 1.21.)
419 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
420 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
421 fchflags without defining UF_NODUMP. (Addresses Debian
424 * flushb.c: Use platform independent method of defining the
425 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
426 since on newer glibc's BLKFLSBUF is defined there.
428 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
429 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
430 to support byte swapping even if we don't support the
431 conversion functions. (Fixes Debian bug #101686).
433 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
434 since the byte-swapping code all assumes the
435 ext2_dir_entry structure. (It's a question of whether or
436 not name_len should be byte-swapped or not, and whether
437 it's a 16 bit or 8 bit field.)
439 2001-06-15 Theodore Tso <tytso@valinux.com>
441 * Release of E2fsprogs 1.21
443 2001-06-15 Theodore Tso <tytso@valinux.com>
445 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
446 file which is generated and is therefore found in the
447 build directory, not source directory.
449 * ismounted.c (check_mntent_file): Use a test file in / to check
450 to see if the root filesystem is mounted read-only. This
451 protects against the case where /etc might not be on /, as
452 well as the case where /etc/mtab doesn't exist. (Both are
453 should-never happen scenarios, but you never know...)
455 2001-06-14 Theodore Tso <tytso@valinux.com>
457 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
458 Remove unneeded #pragma argsused, since the arguments are
461 2001-06-13 Theodore Tso <tytso@valinux.com>
463 * ext2_types.h.in: If linux/types.h has been defined, then don't
464 try to redefine the typedefs.
466 * Makefile.in (HFILES): Add ext2_types.h to the list of files
467 which should be installed.
469 * ismounted.c (check_mntent_file): Work around GNU hurd brain
470 damage. Addresses Debian bug #100304.
472 * Makefile.in: Limit some .o files from being included into the
473 library if --disable-debugfs, --disable-swapfs,
474 --disable-imager, or --disable-resizer are used.
476 2001-06-12 Theodore Tso <tytso@valinux.com>
478 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
479 function, and use the ext2fs_badblocks_* functions
482 2001-06-11 Theodore Tso <tytso@valinux.com>
484 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
485 ext2fs_mark_generic_bitmap and
486 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
487 functions. (This saves space and doesn't significantly
488 change the speed of e2fsck on a P-III.)
490 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
491 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
492 include the byte-swapping logic if ENABLE_SWAPFS is turned
493 on or if we're on a big-endian machine.
495 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
496 set EXT2_FLAG_SWAP_BYTES, instead of using
499 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
500 autoconf to determine whether or not return
501 EXT2_FLAG_SWAP_BYTES.
503 2001-06-10 Theodore Tso <tytso@valinux.com>
505 * Makefile.in: Remove the dependence on the libe2p library.
507 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
508 with direct usage of the ioctl/fchflags so that we don't
509 have to depend on the libe2p library.
511 2001-06-08 Theodore Tso <tytso@valinux.com>
513 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
514 when trying to find a 32-bit wide type.
516 * icount.c (insert_icount_el): Fix the code used to estimate the
517 size of the new icount array to be more intelligent, to
518 avoid reallocating the array too many times. Thanks to
519 Enrique Perez-Terron for pointing this out.
521 2001-06-02 Theodore Tso <tytso@valinux.com>
523 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
524 for a symlink to determine whether it is a fast symlink.
526 2001-06-01 Theodore Tso <tytso@valinux.com>
528 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
529 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
531 2001-05-25 Theodore Tso <tytso@valinux.com>
533 * Release of E2fsprogs 1.20
535 2001-05-25 Theodore Tso <tytso@valinux.com>
537 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
538 some to clean up Andreas's patches. Use strncpy instead
539 of strcpy to save the root's mountpoint. Clean up #ifdef
540 structure. Remove uneeded variable in testing/debug driver.
542 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
544 * ismounted.c: Add check for root device which doesn't depend on
545 /etc/fstab or /proc/mounts to be correct. Don't call
546 endmntent() before we are done with mnt struct.
548 2001-05-23 Theodore Tso <tytso@valinux.com>
550 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
553 2001-05-21 Theodore Tso <tytso@valinux.com>
555 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
556 make room for pre-existing usage of
557 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
558 the same codepoint as EXT2_BTREE_FL.
560 2001-05-20 Theodore Tso <tytso@valinux.com>
562 * ext2fs.h: #include <> instead of "" for ext2fs and et header
563 files, since they will be installed in /usr/include
565 2001-05-14 Theodore Tso <tytso@valinux.com>
567 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,

580 Adjust all files in this directroy to include this file.
582 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
585 2001-05-05 Theodore Tso <tytso@valinux.com>
587 * fileio.c (ext2fs_file_read): Factored out common code and
588 cleaned up function. Fixed a bug where if there was an
589 error reading from the disk, the number of bytes read
590 wasn't reliably set. (Fixes Debian bug #79163)
591 (ext2fs_file_write): Factored out common code and made
592 function more efficient; if writing a full block, don't
593 bother to do a read-modify-write cycle.
595 2001-05-04 Theodore Tso <tytso@valinux.com>
597 * dirblock.c (ext2fs_read_dir_block): Check for an directory
598 record length which isn't a multiple four, and treat that
599 as an invalid. Scan the directory and return an error
600 (EXT2_ET_DIR_CORRUPTED) if the directory records are
602 (ext2fs_write_dir_block): If while byte-swapping the
603 directory block, if there's an error, abort and return
604 EXT2_ET_DIR_CORRUPTED.
606 2001-05-02 Theodore Tso <tytso@valinux.com>
608 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
609 image_header field in the ext2_filsys structure
611 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
612 * inode.c (ext2fs_read_inode):
613 * rw_bitmaps.c (read_bitmaps):
614 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
616 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
617 sure the full bitmap is saved.
619 2001-05-01 Theodore Tso <tytso@valinux.com>
621 * e2image.h (struct ext2_image_hdr): Add space for the device name
624 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
625 make sure the rec_len is a multiple of 4, to prevent
626 bus-errors on architectures which care about mis-aligned
629 2001-04-25 Theodore Tso <tytso@valinux.com>
631 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
632 query the device sizes using the BLKGETSIZE ioctl.
634 2001-04-16 Theodore Tso <tytso@valinux.com>
636 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
637 before checking /etc/mtab. The EXT2_MF_READONLY flag is
638 now set from the /etc/mtab options field for all
639 filesystems, not just the root filesystem. Add debugging
640 code to make it easier to test ext2fs_check_if_mounted().
642 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
643 check; return an error if there's an attempt to create a
644 journal less than 1024 filesystem blocks.
646 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
647 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
649 2001-02-20 Theodore Tso <tytso@valinux.com>
651 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
654 * tst_byteswap.c: New function to test the byteswap functions.
655 Add to regression test suite.
657 2001-02-08 Theodore Tso <tytso@valinux.com>
659 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
661 2001-02-07 Theodore Tso <tytso@valinux.com>
663 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
664 of s_first for external devices to always be 1, since
665 jsb->s_first is always relative to the start of the
666 journal superblock. Use htonl(1) when setting s_nr_users.
668 2001-01-17 Theodore Ts'o <tytso@valinux.com>
670 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
671 device number of the filesystem (instead of the journal)
672 was being dropped into s_journal_dev.
674 2001-01-15 Theodore Ts'o <tytso@valinux.com>
676 * initialize.c (ext2fs_initialize): Add support for initializing
677 the ext2 superblock for external journal devices. This
678 basically means we don't bother to allocate any block
681 * openfs.c (ext2fs_open): Only open external journal devices if
682 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
683 ext2fs_open. When opening such devices, don't try to read
684 the block group descriptors, since they're not there.
686 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
688 * mkjournal.c: Export a new function,
689 ext2fs_create_journal_superblock(), which allocates and
690 returns a buffer containing a journal superblock. This is
691 needed by mke2fs to create an external journal. Rewrote
692 ext2fs_add_journal_device() so that it no longer creates
693 the external journal, but rather adds a filesystem to an
694 existing external journal. It handles all of the UUID
697 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
698 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
699 Changed function prototype for ext2fs_add_journal_device().
701 2001-01-14 Theodore Ts'o <tytso@valinux.com>
703 * closefs.c (ext2fs_flush): Don't write out anything beyond the
704 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
707 2001-01-12 Theodore Ts'o <tytso@valinux.com>
709 * imager.c: Fix gcc -Wall complaints and a series of bugs where
710 retval wasn't set correctly. (Thanks to Andreas Dilger
711 for pointing this out.)
713 2001-01-11 <tytso@snap.thunk.org>
715 * flushb.c (ext2fs_sync_device): New function which centralizes
716 all of the places which might try to use the BLKFLSBUF
717 or FDFLUSH ioctls (and usually failing to define them
718 since the system header files don't usually do this for
719 us, and we're trying to avoid usage of kernel include
722 2001-01-10 <tytso@snap.thunk.org>
724 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
725 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
726 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,

729 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
730 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
731 ext2_ino_t, to protect applications that attempt to
732 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
733 changes ino_t(!?). So we use ext2_ino_t to avoid an
734 unexpected ABI change.
736 2001-01-05 <tytso@snap.thunk.org>
738 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
739 we may overrun allocated memory in case of a corrupted
740 filesystem (or an e2fsck test case :-) when byte-swapping
743 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
745 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
746 complaints including a missing return 0 at the end of
747 ext2fs_add_journal_device.
749 2001-01-03 <tytso@snap.thunk.org>
751 * Makefile.in: Link in libe2p when creating libext2fs as a shared
752 library, since mkjournal.c now references fsetflags().
754 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
755 Dilger's changes (with fixups) to allow on-line creation
758 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
759 EXT2_FLAG_SUPER_ONLY, which the close routines to only
760 update the superblock, and not the group descriptors.
762 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
764 * ismounted.c: add ext2fs_check_mount_point() function, which will
765 optionally return the mount point of a device if mounted
767 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
769 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
770 ext2fs_add_journal_inode()
772 2001-01-01 <tytso@snap.thunk.org>
774 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
775 source (but not binary) compatibility of some users of the
776 ext2 library. They should just simply do a global search
777 and replace of struct ext2fs_sb with struct
778 ext2_super_block, and use their own private copy of
779 ext2_fs.h if they aren't already.
781 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
782 Replace use of ext2fs_sb with ext2_super_block.
784 2000-12-31 <tytso@snap.thunk.org>
786 * ext2fs.h: Cleaned up header file by removing definitions of
787 feature flags that might not have been defined in older
788 ext2 header files. Now that we're using our own
789 include/linux/ext2fs.h header file, this can never happen.
791 * jfs_dat.h: Removed old header file which is no longer needed.
793 2000-12-13 Theodore Ts'o <tytso@valinux.com>
795 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
796 by Andreas Dilger to update the filesystem revision to
799 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
802 2000-12-09 <tytso@snap.thunk.org>
804 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
805 ext2fs_add_journal_device): Add a new argument to the APIs
806 of these function, which is a flags word. This is used to
807 allow the creation of a V1 superblock for those folks who
808 are using ext3 0.3b in production. Note, the user-land
809 interface for getting at this flag won't be documented, as
810 the V1 superblock is deprecated.
812 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
813 which creates a V2 superblock instead of a V1 superblock.
815 2000-11-21 <tytso@snap.thunk.org>
817 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
818 out by Andreas Dilger.
820 2000-11-05 <tytso@snap.thunk.org>
822 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
823 ext2_fs.h, Makefile.in: New file that has routines that
824 save ext2fs metadata to a file.
826 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
828 * e2image.h: New file which defines the file format for the ext2
829 image file. (Saved copy of ext2 metadata to a file as a
830 saving throw against worst-case damage.)
832 2000-11-01 <tytso@snap.thunk.org>
834 * inode.c (ext2fs_flush_icache): Add new function
835 ext2fs_flush_icache() which flushes the internal inode
836 cache. Applications which modify the inode table blocks
837 directly must call this function.
839 2000-10-26 <tytso@snap.thunk.org>
841 * mkjournal.c: Add #include of netinet/in.h, since Solaris
842 requires it for ntohl().
844 * ext2_io.h (io_channel_write_byte): Add new interface to allow
845 callers to write specific byte ranges. This is an
846 optional interface, which not all IO channels may
849 * unix_io.c (unix_write_byte):
850 * test_io.c (test_write_byte): Add implementation of the
853 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
854 function which writes the primary superblock. If the IO
855 channel supports writing raw bytes directly, only fields
856 which were modified are written to the disk. This makes
857 it safe(r) to use utilities like tune2fs on a mounted
860 * freefs.c (ext2fs_free): Free the original superblock if it is
863 * openfs.c (ext2fs_open): Store a copy of the original superblock
866 * ext2fs.h: Add a field to store the original superblock in the
867 ext2 context structure.
869 2000-10-24 <tytso@snap.thunk.org>
871 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
872 don't need to use llseek).
874 2000-10-24 <tytso@valinux.com>
876 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
877 creating an ext3 journal on a filesystem.
879 2000-08-21 <tytso@valinux.com>
881 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
883 2000-08-22 <tytso@valinux.com>
885 * unix_io.c: Make massive changes to support a multiple block
886 writethrough cacheing.
888 * ext2_io.h: Added flags field to the io_channel structure.
890 2000-08-19 <tytso@valinux.com>
892 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
893 provides the function ext2fs_find_block_device(). This
894 function returns the pathname to a block device, given its
897 2000-07-13 <tytso@valinux.com>
899 * Release of E2fsprogs 1.19
901 2000-07-07 Theodore Ts'o <tytso@valinux.com>
903 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
904 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
905 list of filesystem flags supported by the library.
907 2000-07-04 Theodore Ts'o <tytso@valinux.com>
909 * ext2fs.h: Update to include latest journalling additions to the
912 * dll/jump.funcs: Add new jumptable entries for
913 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
914 ext2fs_badblocks_equal.
916 * tst_badblocks.c: Update test program to test
917 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
919 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
920 writes out bad blocks list to a file.
922 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
923 changes the callback function to take two additional
924 arguments; a private blind pointer supplied by the caller,
925 and pointer to a char * containing a pointer to the
928 * badblocks.c (ext2fs_badblocks_equal): Add new function which
929 returns true if two badblocks list are equal.
931 * Makefile.in: Remove explicit link of -lc in the shared library.
932 (It shouldn't be necessary, and is harmful in some cases).
934 2000-06-10 Theodore Ts'o <tytso@valinux.com>
936 * getsize.c (main): Add debugging code under #ifdef DEBUG
938 2000-05-27 Theodore Ts'o <tytso@valinux.com>
940 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
941 earlier, so that if there's an error reading it, we can
942 more cleanly back out of the operation.
944 2000-05-25 <tytso@snap.thunk.org>
946 * getsize.c (ext2fs_get_device_size): Use open64() instead of
947 open() if it exists. Under linux, manually define the
948 ioctl for BLKGETSIZE if it isn't already defined and it's
951 * unix_io.c (unix_open): Use open64() instead of open() if it
954 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
955 available (and prototypes are defined) use it in
956 preference to llseek.
958 * Makefile: Add hack dependency rule so that parallel makes work
961 2000-05-18 Theodore Ts'o <tytso@valinux.com>
963 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
965 2000-04-03 Theodore Ts'o <tytso@valinux.com>
967 * block.c: Readibility tweak in conditionals involving
970 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
971 how to define __s64 and __u64. Turn off "compression is
972 experimental" warning if the cpp macro
973 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
975 2000-02-11 <tytso@snap.thunk.org>
977 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
978 Conditionally include Compression as a supported type if
979 ENABLE_COMPRESSION (via --enable-compression) is turned on.
981 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
983 2000-02-08 <tytso@snap.thunk.org>
985 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
986 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
987 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
988 Change to return the previous state of the bit that is
989 being marked or unmarked. For speed optimization.
991 2000-02-02 Theodore Ts'o <tytso@valinux.com>
993 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
995 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
996 needed any more; we know it will always be i_generation.
997 Add support for swapping the high bits of the uid and gid.
999 1999-11-19 <tytso@valinux.com>
1001 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1002 counts if the link was successful. Patch suggested by
1005 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
1006 the source directory.
1008 1999-11-10 <tytso@valinux.com>
1010 * Release of E2fsprogs 1.18
1012 1999-11-08 <tytso@valinux.com>
1014 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1015 since ext2fs_badblocks_list_free was moved to freefs.c.
1017 * tst_badblocks.c: Use the newer badblocks API names. Add
1018 duplicate blocks to the test inputs to test dealing with
1019 adding blocks which are already in the badblocks list.
1021 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1022 of the list, use a shortcut O(1) operations instead of an
1023 O(n) operation. (Idea suggested by David Beattie.)
1025 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1026 of badblocks_list_free(), to save a procedure call.
1028 1999-10-26 <tytso@valinux.com>
1030 * Release of E2fsprogs 1.17
1032 1999-10-26 <tytso@valinux.com>
1034 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1035 seem to handle ~0UL the same way as they used to.
1037 1999-10-25 <tytso@valinux.com>
1039 * nt_io.c (_OpenNtName): Open the device using
1040 FILE_SYNCHRONOUS_IO_NONALERT instead of
1041 FILE_SYNCHRONOUS_IO_ALERT
1042 (nt_open): At the end of the device open routine, unlock
1043 the drive but do not dismount it.
1045 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
1048 1999-10-22 <tytso@valinux.com>
1050 * Release of E2fsprogs 1.16
1052 1999-10-22 <tytso@valinux.com>
1054 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1056 * link.c (ext2fs_link): This call now uses the low three bits of
1057 the flags parameter to pass the directory filetype
1058 information; it will set the directory entry FILETYPE
1059 information if the filesystem supports it.
1061 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1062 option is set, then create the '.' and '..' entries with
1063 the filetype set to EXT2_FT_DIR.
1065 1999-09-24 <tytso@valinux.com>
1067 * nt_io.c: New file which supports I/O under Windows NT.
1069 1999-09-07 <tytso@valinux.com>
1071 * ext2fs.h: Add new fields for journalling and define new
1072 feature bits used by newer filesystems: IMAGIC_INODES,
1073 HAS_JOURNAL, RECOVER.
1075 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1076 we update the inode block count and size files so that the
1077 block count field is updated correctly when we create an
1080 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1082 * Release of E2fsprogs 1.15
1084 1999-06-23 <tytso@valinux.com>
1086 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1087 kernels that use i_generation instead of i_version. Patch
1088 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1090 1999-06-21 <tytso@valinux.com>
1092 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1093 directory entry before calling the callback function.
1094 This should prevent some core dumps of insufficiently
1095 paranoid callback functions.
1097 1999-05-29 <tytso@rsts-11.mit.edu>
1099 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1101 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1102 that we don't handle writing yet (we do). Fixed bug where
1103 we weren't allocating a big enough buffer for ext2_bmap.
1105 1999-05-03 <tytso@rsts-11.mit.edu>
1107 * openfs.c (ext2fs_open): Check to make sure that the number of
1108 blocks per group is not zero --- if so, it must be a bad
1111 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1113 * Release of E2fsprogs 1.14

1118 the inode number is zero; if it's zero, return
1119 EXT2_ET_BAD_INODE_NUM.
1121 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1123 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1124 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1127 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1129 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1130 non-Linux case to use EINVAL by default, unless it isn't
1131 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1134 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1136 * Release of E2fsprogs 1.13
1138 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1140 * Makefile.in: Updated dependencies.
1142 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1144 * initialize.c (ext2fs_initialize): Make sure that we allocate
1145 enough inodes so that we can make a valid filesystem.
1147 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1149 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1151 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1152 function declaration.
1154 * dblist.c (make_dblist): Add safety check in case the dblist
1155 pointer passed in is null (in which case, assign it to
1156 fs->dblist). Fixed some signed/unsigned warnings.
1158 * bmap.c: Make addr_per_block be of type blk_t to avoid
1159 signed/unsigned warnings.
1161 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1162 function declaration.
1164 * get_pathname.c (get_pathname_proc): Use return value from
1165 ext2fs_get_mem, instead of checking if &gp->name is
1168 * dir_iterate.c (ext2fs_process_dir_block):
1169 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1170 from the function declaration.
1172 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1173 return the error directly instead of jumping to the
1174 cleanup routine, since we don't need to do any cleanup.
1176 * alloc_table.c (ext2fs_allocate_group_table): Make this
1177 function take a dgrp_t for its group argument.
1179 * ext2fs.h: Make dgrp_t an __u32 type, and make
1180 fs->desc_group_count be of type dgrp_t.
1182 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1184 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment

1190 * Release of E2fsprogs 1.12
1192 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1194 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1195 appropriate for all of the block group copies, so that
1196 it's clear where the beginning of the filesystem is on the
1197 disk. (For when the partition table gets scrod.)
1199 * ext2fs.h: Change the name of the feature from
1200 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1201 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1203 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1205 * inode.c (get_next_blockgroup): Fix bug where if
1206 get_next_blockgroup() is called early because of a missing
1207 inode table in a block group, the current_inode counter
1208 wasn't incremented correctly.
1210 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1212 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1213 against a completely trashed bad block inode.
1215 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1217 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1218 the stride length hits a bad value, we retry the block
1219 allocation starting at the beginning of the block group.
1221 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1222 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1223 e2_blkcnt_t to avoid collision with LFS API.
1225 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1227 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1228 way that avoids overflows on disk sizes greater than 4GB.
1230 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1232 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1233 return type for comparison functions for qsort.
1235 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1238 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1240 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1243 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1244 evade a potential problem with glibc's header files trying
1245 to spike out linux/types.h.
1247 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1248 include the old size of the memory, which is needed for
1249 some braindamaged memory allocation systems that don't
1252 * badblocks.c (ext2fs_badblocks_list_add):
1253 bb_inode.c (clear_bad_block_proc):

1257 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1258 pass the old size of the memory to be resized to
1259 ext2fs_resize_mem().
1261 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1263 * Makefile.in: Change to use new installation directory variables
1264 convention. Fix uninstall rules to take $(DESTDIR) into
1267 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1269 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1270 with 32 bit longs, then we need to manually define __s64
1271 and __u64, since the current kernel header files don't
1272 define these if __STRICT_ANSI__ is defined. This is a
1273 problem if we are compiling with full GCC warnings, since
1274 we do need 64 bit support.
1276 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1277 since we're not using ext2fs_move_blocks() and there
1278 is some question as to its usefulness in its current
1281 * bmap.c (block_bmap): Remove unused function.
1283 * bmove.c (process_block): Fix -Wall warning.
1285 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1287 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1288 contain the offset into the inode.i_blocks array when
1289 ref_block is zero. Since we haven't done a formal
1290 release of e2fsprogs since block_iterate2 was first
1291 introduced, I removed block_iterate2, and renamed
1292 block_iterate3 to be block_iterate2.
1294 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1295 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1296 use of block_iterate and block_iterate2 to
1297 block_iterate2 with the new prototype for the
1298 interator function. (using blkcnt_t forr blockcount)
1300 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1302 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1303 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1304 conditional defines of new features COMPAT_DIR_PREALLOC,
1305 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1306 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1307 the library to declare that we support COMPAT_DIR_PREALLOC,
1308 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1310 * fileio.c: Rename function ext2fs_file_llseek to be
1311 ext2fs_file_lseek, which is more accurate.
1313 * block.c: Add new function ext2fs_block_iterate3 which calls
1314 the iterator function with the blockcount argument of
1315 type blkcnt_t. This version of the function is
1316 allowed to handle large files; the other fucntions are
1319 * ext2fs.h: Add new type blkcnt_t
1321 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1323 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1324 field wasn't getting correctly incremented for sparse
1325 files when the indirect or doubly-indirect block
1326 specified in the inode was zero.
1328 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1330 * unlink.c (unlink_proc):
1331 * lookup.c (lookup_proc):
1332 * link.c (link_proc):
1333 * get_pathname.c (get_pathname_proc):
1334 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1335 from dirent->name_len, so it can be used for other
1338 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1339 and indicate that we have support for this incompatible
1342 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1344 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
1346 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1348 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
1349 number of directories when the block group information is
1352 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1354 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1355 inode table is missing so that we catch the case where the
1356 first block group is missing.
1358 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1361 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1363 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1365 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1367 * test_io.c (test_flush): Add a debugging printf when the flush
1370 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1371 read in, return right away.
1373 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1375 * bitops.h: Don't try to do i386 inline asm functions if the
1378 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1379 instead of linux/types.h, and e2_bitops.h instead of
1382 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1385 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1387 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1388 so that we don't need to call get_next_blockgroup() the
1389 first time around. Saves a bit of time, and prevents us
1390 from needing to assign -1 to current_group (which is an
1393 * icount.c (insert_icount_el): Cast the estimated number of inodes
1394 from a float to an ino_t.
1396 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
1397 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1398 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

1406 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1407 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
1408 defined, then assume all of the
1409 ext2-specific header files are in a flat directory.
1411 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1412 all assignments from void * to be compatible with C++.
1414 Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1416 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
1417 make sure the contents of the disk are flushed to disk.
1419 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1421 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
1422 avoid C++ namespace clash.
1424 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
1425 avoid C++ namespace clash.
1427 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
1428 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
1429 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
1430 unlink.c: Change private to be priv_data (to avoid C++
1433 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1435 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1436 paranoid about validating the directory counts from the
1437 block group information.
1439 * all files: Don't include stdlib.h anymore; include it in
1440 ext2_fs.h, since that file requires stdlib.h
1442 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1444 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1445 bitmap is loaded, and return an error if it is not.
1446 (expand_dir_proc): Only use ext2fs_write_dir_block when
1447 writing a directory block, not when writing out a fresh
1450 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1472 * Rename new error codes to _ET_ in them for consistency.
1474 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1476 * [all files, basically]: Added definition of ext2fs_get_mem,
1477 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1478 changed all library routines to use these wrapper functions.

1498 * fileio.c: New file which implements simple file reading and
1501 * alloc.c (ext2fs_alloc_block): New function which allocates a
1502 block, zeros it, and updates the filesystem accounting

1521 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1523 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
1525 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1529 * icount.c (ext2fs_icount_validate):
1530 * bmove.c (process_block): Fix lint error in type for fprintf().
1532 Mon Sep 15 11:45:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1534 * inode.c (ext2fs_check_directory): Add support for the callback
1535 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
1537 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1539 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
1540 padding of the bitmap to be all one's.
1542 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
1544 * llseek.c: Added missing semicolon to glibc fixup declaration of
1547 * bmove.c: Add #include of errno.h
1549 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1551 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
1552 added a new field to the io_channel (app_data).
1554 * io.h: Add a new element to the io_channel structure, app_data.
1556 * initialize.c, openfs.c: Set io->app_data to point at the
1559 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1561 * io.h: Change the prototype of ext2fs_llseek() to use int's
1562 instead of unsigned int's.
1564 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1565 to make life easer for GNU Libc 2.
1567 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1568 filesystem has its bitmaps stored as 32-bit words with bit
1569 0 as the LSB of each word. Thus a bitmap with only bit 0
1570 set would be, as a string of bytes, 00 00 00 01 00 ... To
1571 cope with this, we byte-reverse each word of a bitmap if
1572 we have a big-endian filesystem, that is, if we are *not*
1573 byte-swapping other word-sized numbers.
1575 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1591 * read_bb.c (ext2fs_read_bb_inode):
1592 * cmp_bitmaps.c (ext2fs_compare_inode_bitmap): Use blk_t, ino_t
1593 and size_t where appropriate.

1642 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1644 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1645 is zero, then return EXT2_IO_LLSEEK_FAILED.
1647 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1649 * Release of E2fsprogs 1.11
1651 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1653 * dblist.c (ext2fs_dblist_count): Added new function which returns
1654 the number of directory blocks in dblist.
1656 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1658 * unix_io.c (unix_flush): Make the io_channel flush function do a
1659 fsync to flush the kernel buffers to disk.
1661 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1663 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1664 current inode number wasn't being set by the
1665 goto_blockgroup function.
1667 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1669 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1670 of blocks which need to be moved, and moves those blocks
1671 to another location in the filesystem.
1673 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1674 bitmap, make sure all of the new parts of the bitmap are
1677 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1679 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1680 wasn't being returned to the caller.
1682 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1683 ext2fs_allocate_group_table() which sets the group tables
1684 for a particular block group. The relevant code was
1685 factored out of ext2fs_allocate_tables().
1687 * dblist.c (make_dblist): Adjust the initial size of the directory
1688 block list to be a bit more realistic (ten plus twice the
1689 number of directories in the filesystem).
1691 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1693 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1694 ext2fs_badblocks_list_test would test the list (and exceed
1695 array boundaries) if there were no bad blocks on the bad
1696 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1698 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1700 * Release of E2fsprogs version 1.10
1702 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1704 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1705 inode and block bitmaps based on the RAID 0 stride
1706 parameter (which is passed by mke2fs).
1708 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1709 mke2fs to communicate the stride length to
1710 ext2fs_allocate_tables()
1712 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1714 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1715 systems. (We can't assume that the new filesystem types
1718 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1720 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1721 allocate the inode and block bitmaps inside block group at
1724 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1726 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the

1749 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1751 (unix_close, test_close): Decrement the refcount and only
1752 close the io_channel if the refcount goes to 0.
1754 * io.h: Add refcount to the io_channel structure. Add new macro
1755 interface io_channel_bumpcount() to bump the refcount.
1757 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1759 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1760 cache in the filesystem handle, instead of the inode cache
1761 in a static variable.
1763 * freefs.c: Added static function to free the inode cache (called by
1766 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1768 * ext2fs.h: Added pointer to the inode_cache structure.
1770 * block.c (block_iterate_ind, block_iterate_dind,
1771 block_iterate_tind): If there are holes in the indirect,
1772 doubly indirect, or triply indirect blocks, increment the
1773 block count field automatically.
1775 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1777 * Release of E2fsprogs version 1.09
1779 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1781 * version.c (ext2fs_parse_version_string): Check the passed in
1782 version string (instead of the hard-coded one).
1784 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1785 greater filesystem size, clamp it to prevent allocating a
1786 block or inode bitmap beyond the filesystem.
1788 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1789 overhead calculation was accidentally removed.
1791 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1793 * Release of E2fsprogs version 1.08
1795 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1797 * dblist.c (ext2fs_set_dir_block): New function which sets the
1798 block of a dblist entry, given the directory inode and
1801 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1803 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1804 inode bitmaps at staggered locations across the block
1805 groups, to avoid concentrating the bitmaps on a small
1806 number of disks when using striped RAID arrays.
1808 * initialize.c (ext2fs_initialize): By default, choose the maximum
1809 possible number of blocks per group (based on the size of
1810 the bitmaps in the blocksize).
1812 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1814 * initialize.c (ext2fs_initialize): Add support for
1815 EXT2_COMPAT_SPARSE_SUPER feature.
1817 * closefs.c (ext2fs_bg_has_super): New function to determine
1818 whether or a particular block group should have a
1819 superblock and block group descriptor. Used for the
1820 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1821 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1822 or not the superblock should be written out for the block
1825 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1826 for sparse duplicate superblocks.
1828 * version.c (ext2fs_get_library_version): New function which
1829 returns the library version.
1831 * version.c (ext2fs_parse_version_string): New function which
1832 parses a version string and returns a version number,
1833 so application programs can compare version numbers as
1836 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1838 * icount.c (ext2fs_create_icount): Change function so that it also
1839 takes a new argument which contains a "hint" icount
1840 structure. This "hint" icount allows the create function
1841 to set up the sorted list in advance. This reduces
1842 significantly the amount of data moving needed to insert
1843 these inodes into the list later.
1845 * icount.c (ext2fs_icount_validate): New function which validates
1846 that the icount structure's rep invariant.
1848 * icount.c (get_icount_el): Completely revamped implementation
1849 to subsume put_icount_el(). Put_icount_el() used to
1850 use an O(N) implementation to insert in the middle
1851 of the icount list. It now uses a O(ln N) to search
1852 for where the icount should be inserted, and then uses
1853 a memcpy to move the list down (instead of a for loop).
1855 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1856 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1857 to see if the inode is within bounds; if it isn't, return
1860 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1861 when a bad inode number is passed to test_generic_bitmap
1862 to be EXT2FS_TEST_ERROR instead of the wrong
1863 EXT2FS_UNMARK_ERROR.
1865 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1867 * Release of E2fsprogs version 1.07
1869 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1871 * Makefile.in (ELF_VERSION): Change version to be 2.2
1873 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1875 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1876 ext2fs_fast_test_block_bitmap_range().
1878 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1879 ext2fs_test_block_bitmap_range: New inline functions which
1880 test to see whether a contiguous range of blocks is
1883 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1885 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1886 use ext2fs_badblocks_* instead of badblocks_*
1888 * bb_compat.c: New file which translates between old badblocks_*()
1889 names to ext2fs_badblocks_*()
1891 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1892 link.c (since e2fsck doesn't use ext2fs_unlink()).
1894 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1895 bitmap resizing routine moved from bitmaps.c, since e2fsck
1896 doesn't need to use this function.
1898 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1899 since e2fsck only needs ext2fs_lookup.
1901 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1903 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1904 already set; this is needed so that programs like dump
1905 which use the inode scan functions will deal with
1906 filesystems that have bad blocks in the inode table.
1908 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1910 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1911 Moved to ext2fsP.h, since it doesn't need to be part of
1912 the public interface.
1914 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1916 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1918 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1919 directory block list abstraction. (Code moved from
1922 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1923 to inode.c (since no one else should be peeking inside it!)
1925 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1927 * openfs.c (ext2fs_open): Check the feature set in the ext2
1928 superblock, and refuse to open filesystems if they contain
1929 incompatible features. (Can be overriden with the
1932 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1934 * block.c (ext2fs_block_iterate2): Added new function
1935 ext2fs_block_iterate2 which changes the function
1936 signature of the callback function to include the
1937 referencing block and offset.
1939 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1940 ext2fs_inode_scan_goto_blockgroup which allows an
1941 application to jump to a particular block group while
1942 doing an inode scan.
1944 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1946 * dirblock.c: Include string.h, since we use memcpy().
1948 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1950 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1951 a long not an int; this doesn't matter on i386 machines,
1952 but it does on Alpha's.
1954 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1956 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1957 table pointer is NULL, then return an error indicating
1958 that the inode table is missing.
1959 (get_next_blockgroup, get_next_blocks,
1960 ext2fs_get_next_inode): Don't treat a missing inode table
1961 as permanent error. Return MISSING_INODE_TABLE, but as an
1962 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1964 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1965 ext2fs_write_inode_bitmap): If the inode or block bitmap
1966 block is zero, then don't write out the inode or block
1967 bitmap. The idea here is to avoid stomping on the
1969 (read_bitmaps): If the inode or block bitmap block is
1970 zero, then fill in that portion of the inode or block
1971 bitmap with all zeros.
1973 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1974 blocks in inode table when the inode table size is
1975 non-standard (and can therefore span blocks).
1977 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1979 * alloc.c (ext2fs_new_block): Fix fencepost error in
1980 ext2fs_new_block; make sure we don't try to allocate the
1981 first block beyond the end of the filesystem.
1983 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1985 * inode.c (check_for_inode_bad_blocks): New function called by
1986 get_next_blocks() to avoid reading in bad blocks marked in
1987 fs->badblocks. Inodes located in bad blocks are returned
1988 by ext2fs_get_next_inode() returns the error code
1989 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1991 * alloc_tables.c (ext2fs_allocate_tables): New function which
1992 performs the part of mke2fs's job of allocating the
1995 * test_io.c (test_close): IO manager which is used for testing
1998 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2000 * inode.c (ext2fs_get_next_inode): Separate out the function of
2001 setting up for a new block group to get_next_blockgroup().
2002 Separate out the function of reading in blocks of the
2003 inode table to get_next_blocks().
2005 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
2007 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2008 blocks to the badblock list in sorted order. This allows
2009 badblocks_list_test to be coded using a binary search for
2012 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2014 * Release of E2fsprogs version 1.06
2016 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2018 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2019 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2022 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2023 set, then only write out the master superblock.
2025 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2027 * block.c (ext2fs_block_iterate): Fixed bug which caused
2028 block_iterate to fail to handle HURD created filesystems;
2029 it tested the inode translator field before the inode was
2032 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2034 * initialize.c (ext2fs_initialize): Make sure the description for
2035 the inode bitmap is set correctly.
2037 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

2041 * Release of E2fsprogs version 1.05
2043 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2045 * initialize.c: Override the kernel's idea of default
2046 checkinterval from 0 (never) to 180 days.

2053 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2055 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2056 for shortcut function fs->read_inode() and fs->write_inode().
2057 Added inode_cache to reduce CPU time spent in doing
2060 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
2063 * namei.c (ext2fs_follow_link): New function.
2064 (ext2fs_namei): Extended to have support for chasing
2065 symbolic links. ext2fs_namei() still returns an inode
2066 which is a symbolic link. Symbolic links are only chased
2067 while resolving the containing directory. To chase
2068 symbolic links of the final result, use
2069 ext2fs_follow_link().
2071 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2073 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2075 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2076 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
2078 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2080 * initialize.c (ext2fs_initialize): On systems where the byte
2081 order is not i386 compatible, set the swap_byte flag.
2083 * inode.c (inocpy_with_swap): Check to see if inode contains a
2084 fast symlink before swapping the inode block fields. This
2085 required adding a new argument to inocpy_with_swap to
2086 determine whether the mode field is in host order or not.
2088 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2090 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2091 the sparc, if EXT2_STD_BITOPS set, use the standard
2092 i386-compatible bitmask operations, instead on the
2093 non-standard native bitmask operators.
2095 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2097 * block.c (ext2fs_block_iterate): Cause block iterator to return
2098 the HURD translator block (along with everything else).
2099 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2100 iterator, then don't return any meta data blocks
2101 (including the HURD translator).
2103 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2105 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2107 * uuid.c: New file, containing UUID utility functions.
2109 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2111 * ext2fs.h: Add a definition of the "real" ext2 superblock.

2117 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2119 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2120 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2121 that's a basic value that must be correct for the rest of
2122 the library to work.
2124 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2127 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2163 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
2165 * getsize.c (ext2fs_get_device_size): Open the device read-only
2166 when trying to determine its size.
2168 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
2170 * Release of E2fsprogs version 1.02

2174 * rw_bitops.c (ext2fs_write_block_bitmap):
2175 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2176 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2177 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2178 to avoid conflicts with with kernel include files. Also
2179 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2182 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2184 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
2186 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
2187 s_def_resuid and s_def_resgid for backwards compatibility.
2189 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

2198 * closefs.c: #include <string.h> to pick up memset() declaration
2200 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
2202 * Makefile.in: Added support for BSD shared libraries.
2204 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
2207 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
2209 * unix_io.c (unix_open): Add a double check; if the passed in name
2210 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
2212 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
2214 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

2236 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2237 Move these functions to freefs.c.
2239 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2240 descriptors shadow memory to keep purify quiet. (This
2241 also has the nice benefit that the unused portion of the
2242 shadow descriptors are zeroed out.)
2244 * dirblock.c (ext2fs_write_dir_block): We need to use
2245 dirent->rec_len *before* it's byteswapped to find the
2246 location of the next directory structure!
2248 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2249 cause ext2fs_new_inode to loop infinitely if we're trying
2250 to allocate an inode in group #0 and there are no free
2251 inodes at all in the system.
2253 * closefs.c: #include <errno.h> if it exists.
2255 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2257 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

2263 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
2264 installation directories correctly.
2266 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>

2271 to read/write the directory block.
2273 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
2274 file containing functions for reading and writing
2275 directory blocks (byte swapping if necesssary)
2277 * block.c (block_iterate_ind, block_iterate_dind,
2278 block_iterate_tind): Byte swap the block addresses if
2279 EXT2_SWAP_BYTES is set (and swap them back before writing
2282 * inode.c (inocpy_with_swap): New function.
2283 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
2284 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2286 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2287 the superblock and group descriptors before writing it out.
2289 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2290 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2291 and group descriptors.
2293 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2294 to desp ext2 filesystem structures.
2296 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2297 supplied by Pete A. Zaitcev so that the C language
2298 versions of these functions are more portable. They will
2299 now work on both little and big endian systems, and the
2300 assumption that 32-bit integers are used is gone.
2302 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2303 doing byte swapping.
2305 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2306 byte swapping should take place.
2308 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
2310 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,

2319 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2320 if the magic number is correct, it will be allocated.
2322 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2324 * block.c (block_iterate_ind, block_iterate_dind,
2325 block_iterate_tind): Don't recompute block_nr each loop;
2326 just increment it! Factor check of BLOCK_FLAG_APPEND out
2327 of the loop. Factor mask of BLOCK_CHANGED into changed
2328 variable out of the loop. (block_iterate_ind, in
2329 particular, gets called a lot, so every little
2330 optimization helps.)
2332 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2334 * block.c (block_iterate_ind, block_iterate_dind,

2336 block_iterate_ind and company.
2338 * bitops.h (ext2fs_fast_mark_block_bitmap,
2339 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
2340 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2341 ext2fs_fast_test_inode_bitmap): Add fast version of these
2342 functions, which don't do range checking.
2344 * bitops.h (ext2fs_get_block_bitmap_start,
2345 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2346 ext2fs_get_inode_bitmap_end): Add new accessor functions
2347 which return the start and end points of the bitmaps.
2349 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2351 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2352 instead of llseek. The errno if the offset is too large
2353 and lseek is not supported should be EINVAL, not -EINVAL.
2355 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2357 * Makefile.in: Added support for ELF shared libraries.
2358 Fixed typos in the compilation rules.
2359 (distclean): Added Makefile.
2361 * llseek.c (llseek): New function, if llseek() does not exist in the
2363 (ext2_llseek): Changed to call llseek().
2365 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2367 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
2369 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2371 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2373 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2374 the S_*, which are normally defined in <sys/stat.h>. This
2375 allows us to compile e2fsprogs on a non-Linux system,
2376 which may have a different value for S_IFDIR.
2378 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2380 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2381 this is a user-mode application!
2383 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2385 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2386 __linux__ so that non-linux systems won't see it.
2388 * alloc.c: Include <errno.h> if possible.
2389 * badblocks.c: Ditto.
2390 * bb_inode.c: Ditto.
2393 * expanddir.c: Ditto.
2394 * get_pathname.c: Ditto.
2395 * initialize.c: Ditto.
2402 * rw_bitmaps.c: Ditto.
2405 * Makefile.in: Rewritten to conform to GNU coding standards and
2406 support separate compilation directories.
2408 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2410 * initialize.c (ext2fs_initialize): Don't allow more than one
2411 bitmaps's worth of inodes in a group.
2413 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2415 * llseek.c (ext2_llseek): Added error checking to the llseek()
2416 compat code to protect against overflow. This only
2417 applies to 1.0 and early 1.1 kernels, which don't support
2418 the llseek() system call.
2420 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2422 * unix_io.c (unix_open): Initialize the read_error and write_error
2423 io_channel pointers to be null.
2425 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2426 found, clear it but don't try to update the filesystem
2427 accounting information, since that's hopeless anyway.
2429 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2430 bloblock_iterate_tind): Check to see if the indirect blocks are
2431 valid before trying to read them.

2434 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2436 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2437 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2438 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2439 illegal block or inode number is passed in, return instead
2440 of trying to test, set, or clear the bit.
2442 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2444 * Makefile: Added a dummy install target in case shared libraries
2447 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2449 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

2455 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
2456 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,

2458 the inode and block bitmaps.
2460 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2461 magic number for a block bitmap instead of an inode bitmap.

2467 badblocks_list_test, badblocks_list_iterate_begin,
2468 badblocks_list_iterate, badblocks_list_iterate_end): Add
2469 magic number checking for the badblocks_list and
2470 badblocks_iterate structures.
2472 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
2473 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
2474 unix_write_blk, unix_flush): Add magic number checking
2475 both for io_channel structure and unix_private_data
2478 * openfs.c (ext2fs_open): Add check for io_manager structure's
2481 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2482 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2483 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2484 * read_bb.c (ext2fs_read_bb_inode):
2485 * read_bb_file.c (ext2fs_read_bb_FILE):
2486 * newdir.c (ext2fs_new_dir_block):
2487 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
2488 * link.c (ext2fs_link, ext2fs_unlink):
2489 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

2496 ext2fs_allocate_block_bitmap):
2497 * bb_inode.c (ext2fs_update_bb_inode):
2498 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
2499 * check_desc.c (ext2fs_check_desc):
2500 * closefs.c (ext2fs_close, ext2fs_flush):
2501 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2506 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2507 openfs.c into its own file.
2509 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2510 structure magic numbers.
2512 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2513 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2514 someone uses the -b option to specify the use of the backup
2515 superblock --- this usually means that the main superblock is
2519 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2520 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2521 revision level to the superblock.
2523 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2530 * initialize.c: Completely revamped the inode and block bitmap
2531 structures, so that they can be better chance of being extensible
2532 in a shared library. They are now their own type, instead of
2533 being a char *. Also, the function signatures of
2534 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2535 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2536 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2537 changed to eliminate the ext2_filsys argument, since it is no
2540 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2542 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2543 system call if available.
2545 * llseek.c: new file. This is the stub calling the llseek system
2546 call which allows supports for 2GB+ file systems.
2548 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2549 the creator operating system.
2551 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2553 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2554 the group descriptor statistics in addition to everything else.
2555 This relieves mke2fs of the responsibility of doing it.
2557 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2558 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2559 not the generic C function equivalents should be included or not.
2561 * openfs.c (ext2fs_open): If a superblock is specified, then use
2562 the backup group descriptors that go along with this superblock,
2563 instead of using the primary group descriptors. This allows
2564 e2fsck to recover filesystems where the primary group descriptors
