1 2002-03-08 Theodore Tso <tytso@mit.edu>
3 * Release of E2fsprogs 1.27
5 2002-03-07 Theodore Tso <tytso@mit.edu>
7 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
9 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
10 tst_byteswap.c: Fix gcc -Wall complaints
12 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
13 (From Philipp Thomas <pthomas@suse.de>)
15 2002-02-25 Theodore Tso <tytso@mit.edu>
17 * ext2_fs.h: Add structure definitions for the directory indexing
20 2002-02-23 Theodore Tso <tytso@mit.edu>
22 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
23 it doesn't break things on mis32, sparc32, and alpha
26 2002-02-21 Theodore Tso <tytso@mit.edu>
28 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
29 we were missing an fclose().
31 2002-02-20 Theodore Tso <tytso@mit.edu>
33 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
34 abstraction interface which exports an ext2 inode.
36 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
37 as a public interface. Change void * to const void * in
38 ext2fs_file_write's interface.
40 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
41 conditional; save a few bytes.
43 2002-02-12 Theodore Tso <tytso@mit.edu>
45 * Makefile.in (tst_badblocks): Add some extra .o files when
46 linking the debugging program tst_badblocks which are
47 needed if we aren't compiling with inline functions enable.
49 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
50 define away __inline__ since it may not be supported.
52 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
53 stripped down jbd_debug that doesn't use variadic
54 arguments. This will cause warnings under AIX, but things
57 2002-02-03 Theodore Tso <tytso@thunk.org>
59 * Release of E2fsprogs 1.26
61 2002-02-03 Theodore Tso <tytso@mit.edu>
63 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
64 so that the number of directories in use is adjusted
67 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
68 which optionally will modify the number of directories
71 2002-01-03 Theodore Tso <tytso@mit.edu>
73 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
74 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
75 which will return deleted directory entries.
76 ext2fs_dir_iterate2 takes a new callback function which
77 is identical with the one used by
78 ext2fs_dblist_dir_iterate(). If the directory entry is
79 deleted, the callback function will be called with the
80 entry paraemter set to DIRENT_DELETED_FILE.
82 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
83 ext2fs_block_alloc_stats): New functions which update
84 block/inode allocation statistics in the bitmaps, block
85 group descriptors, and superblock.
87 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
88 expanddir.c (expand_dir_proc), bb_inode.c
89 (clear_bad_block_proc, set_bad_block_proc,
90 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
91 Update to use new block/inode allocation statistics.
93 2001-12-24 Theodore Tso <tytso@mit.edu>
95 * ismounted.c (is_swap_device): New function used by
96 ext2fs_check_if_mounted and ext2fs_check_mount_point which
97 determines whether or not the specified device is a swap
98 device by using /proc/swaps. More bulletproofing for
99 idiotic/careless system administrators!
101 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
102 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
103 field to struct_ext2_filsys, umask. This field is
104 initialize to 022, and affects ext2fs_mkdir in the obvious
105 way. (In the future umask should also affect new file
106 creation routines, but the fileio functions don't
107 currently support this yes.)
109 * ismounted.c (check_mntent_file): Stat all of the entries in
110 /etc/mtab and/or /proc/mounts in order to catch dim-witted
111 system administrators who might have created alias
114 2001-12-23 Theodore Tso <tytso@mit.edu>
116 * Makefile.in, jfs_user.h: Move linux/jbd.h to
117 ext2fs/kernel-jbd.h, to avoid using the system header
118 file version of hbd.h when using diet glibc (since it
119 forcibly adds /usr/include to the beginning of the
120 include search path.)
122 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
123 include/linux directory.
125 2001-12-16 Theodore Tso <tytso@mit.edu>
127 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
128 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
129 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
131 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
134 2001-12-03 Theodore Tso <tytso@mit.edu>
136 * unix_io.c (unix_open): Make sure the ulimit workaround works
137 regardless of the version of glibc which is used to
140 2001-11-26 Theodore Tso <tytso@mit.edu>
142 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
143 trying to unset the filesize limit if at all possible,
144 if a block device is getting opened. (The filesize limit
145 shouldn't be applied against writes to a block device, but
146 starting in 2.4.10, the kernel is doing this.)
148 2001-11-05 Theodore Tso <tytso@mit.edu>
150 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
151 file on adding a journal to an already-mounted filesystem,
152 try to clear the ext2 file attributes on an already
153 existing .journal file so that we don't fail if on a
154 partially added journal to the filesystem.
156 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
157 which signals that a particular inode should not have the
158 last bits of data (the "tail") be merged with another
159 file. This is necessary to keep LILO happy.
161 2001-09-20 Theodore Tso <tytso@thunk.org>
163 * Release of E2fsprogs 1.25
165 2001-09-16 Theodore Tso <tytso@mit.edu>
167 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
168 which was breaking the build on the Hurd. (Addresses
171 2001-09-13 Theodore Ts'o <tytso@mit.edu>
173 * ismounted.c (check_mntent_file): We now validate the entry in
174 /etc/mtab to make sure the filesystem is really mounted,
175 since some broken distributions (read: Slackware) have
176 buggy boot scripts that don't initialize /etc/mtab before
177 checking non-root filesystems. (Slackware also doesn't
178 check the root filesystem separately, and reboot if the
179 root filesystem had changes applied to it, which is
180 dangerous and broken.)
182 2001-09-02 Theodore Tso <tytso@thunk.org>
184 * Release of E2fsprogs 1.24a
186 2001-08-30 Theodore Tso <tytso@thunk.org>
188 * Release of E2fsprogs 1.24
190 2001-08-30 Theodore Tso <tytso@valinux.com>
192 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
193 changes, since the ioctl number has been reused by another
196 2001-08-15 Theodore Tso <tytso@valinux.com>
198 * Release of E2fsprogs 1.23
200 2001-08-05 Theodore Tso <tytso@valinux.com>
202 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
203 version of the bitmap test routines to speed up these
204 routines. (At some point I may want to make these
205 routines use the find_first_bit functions, but that will
206 add a lot of complexity since it means that these
207 functions will have to break the bitmap abstraction
208 boundary. It's not clear it's worth it.)
210 * mkjournal.c (mkjournal_proc): Remember the last block allocated
211 to speed up ext2fs_new_block().
213 2001-07-29 Theodore Tso <tytso@valinux.com>
215 * finddev.c (scan_dir): Fix memory leak; we weren't calling
216 closedir() when exiting the function in all cases.
218 2001-07-27 Theodore Tso <tytso@valinux.com>
220 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
221 block usable in the journal for external journals to be 2
222 or 3, depending on the blocksize, so that the existing
223 kernel code does the right thing.
225 * getsize.c (ext2fs_get_device_size): Add support for the
226 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
227 from Ben LaHaise, but it's likely this interface won't
230 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
231 when writing the journal superblock, too. (Oops! Needed
232 to make 1k filesystems with external journal to work.)
234 2001-07-26 Theodore Tso <tytso@valinux.com>
236 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
237 to find the journal superblock if the blocksize is 1024.
239 2001-07-21 Theodore Tso <tytso@valinux.com>
241 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
243 2001-07-20 Theodore Tso <tytso@valinux.com>
245 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
246 attribute block, set the filesystem changed bit.
248 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
249 Comment out these functions since we're not using them.
251 2001-07-10 Theodore Tso <tytso@valinux.com>
253 * closefs.c (write_primary_superblock): After writing changes to
254 the primary superblock, update the original superblock
255 copy so we don't have to re-write those changes in the
257 (ext2fs_flush): Clear the superblock dirty flag after
258 we've flushed out changes to disk.
260 2001-07-07 Theodore Tso <tytso@valinux.com>
262 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
263 to avoid register conflicts when compiling in PIC mode.
265 2001-07-04 Theodore Tso <tytso@valinux.com>
267 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
268 Add new functions (C and in i386 assembler) which quickly
269 find bits set in a bitmask.
271 2001-06-23 Theodore Tso <tytso@valinux.com>
273 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
274 ext2_ext_attr.h and ext_attr.c for extended attributes
277 * Release of E2fsprogs 1.22
279 2001-06-22 Theodore Tso <tytso@valinux.com>
281 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
282 descriptor so that adding a journal to a mounted
283 filesystem doesn't die. (Fixes a bug accidentally
284 introduced in e2fsprogs 1.21.)
286 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
287 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
288 fchflags without defining UF_NODUMP. (Addresses Debian
291 * flushb.c: Use platform independent method of defining the
292 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
293 since on newer glibc's BLKFLSBUF is defined there.
295 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
296 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
297 to support byte swapping even if we don't support the
298 conversion functions. (Fixes Debian bug #101686).
300 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
301 since the byte-swapping code all assumes the
302 ext2_dir_entry structure. (It's a question of whether or
303 not name_len should be byte-swapped or not, and whether
304 it's a 16 bit or 8 bit field.)
306 2001-06-15 Theodore Tso <tytso@valinux.com>
308 * Release of E2fsprogs 1.21
310 2001-06-15 Theodore Tso <tytso@valinux.com>
312 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
313 file which is generated and is therefore found in the
314 build directory, not source directory.
316 * ismounted.c (check_mntent_file): Use a test file in / to check
317 to see if the root filesystem is mounted read-only. This
318 protects against the case where /etc might not be on /, as
319 well as the case where /etc/mtab doesn't exist. (Both are
320 should-never happen scenarios, but you never know...)
322 2001-06-14 Theodore Tso <tytso@valinux.com>
324 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
325 Remove unneeded #pragma argsused, since the arguments are
328 2001-06-13 Theodore Tso <tytso@valinux.com>
330 * ext2_types.h.in: If linux/types.h has been defined, then don't
331 try to redefine the typedefs.
333 * Makefile.in (HFILES): Add ext2_types.h to the list of files
334 which should be installed.
336 * ismounted.c (check_mntent_file): Work around GNU hurd brain
337 damage. Addresses Debian bug #100304.
339 * Makefile.in: Limit some .o files from being included into the
340 library if --disable-debugfs, --disable-swapfs,
341 --disable-imager, or --disable-resizer are used.
343 2001-06-12 Theodore Tso <tytso@valinux.com>
345 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
346 function, and use the ext2fs_badblocks_* functions
349 2001-06-11 Theodore Tso <tytso@valinux.com>
351 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
352 ext2fs_mark_generic_bitmap and
353 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
354 functions. (This saves space and doesn't significantly
355 change the speed of e2fsck on a P-III.)
357 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
358 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
359 include the byte-swapping logic if ENABLE_SWAPFS is turned
360 on or if we're on a big-endian machine.
362 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
363 set EXT2_FLAG_SWAP_BYTES, instead of using
366 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
367 autoconf to determine whether or not return
368 EXT2_FLAG_SWAP_BYTES.
370 2001-06-10 Theodore Tso <tytso@valinux.com>
372 * Makefile.in: Remove the dependence on the libe2p library.
374 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
375 with direct usage of the ioctl/fchflags so that we don't
376 have to depend on the libe2p library.
378 2001-06-08 Theodore Tso <tytso@valinux.com>
380 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
381 when trying to find a 32-bit wide type.
383 * icount.c (insert_icount_el): Fix the code used to estimate the
384 size of the new icount array to be more intelligent, to
385 avoid reallocating the array too many times. Thanks to
386 Enrique Perez-Terron for pointing this out.
388 2001-06-02 Theodore Tso <tytso@valinux.com>
390 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
391 for a symlink to determine whether it is a fast symlink.
393 2001-06-01 Theodore Tso <tytso@valinux.com>
395 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
396 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
398 2001-05-25 Theodore Tso <tytso@valinux.com>
400 * Release of E2fsprogs 1.20
402 2001-05-25 Theodore Tso <tytso@valinux.com>
404 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
405 some to clean up Andreas's patches. Use strncpy instead
406 of strcpy to save the root's mountpoint. Clean up #ifdef
407 structure. Remove uneeded variable in testing/debug driver.
409 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
411 * ismounted.c: Add check for root device which doesn't depend on
412 /etc/fstab or /proc/mounts to be correct. Don't call
413 endmntent() before we are done with mnt struct.
415 2001-05-23 Theodore Tso <tytso@valinux.com>
417 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
420 2001-05-21 Theodore Tso <tytso@valinux.com>
422 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
423 make room for pre-existing usage of
424 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
425 the same codepoint as EXT2_BTREE_FL.
427 2001-05-20 Theodore Tso <tytso@valinux.com>
429 * ext2fs.h: #include <> instead of "" for ext2fs and et header
430 files, since they will be installed in /usr/include
432 2001-05-14 Theodore Tso <tytso@valinux.com>
434 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
435 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
436 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

445 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
446 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
447 Adjust all files in this directroy to include this file.
449 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
452 2001-05-05 Theodore Tso <tytso@valinux.com>
454 * fileio.c (ext2fs_file_read): Factored out common code and
455 cleaned up function. Fixed a bug where if there was an
456 error reading from the disk, the number of bytes read
457 wasn't reliably set. (Fixes Debian bug #79163)
458 (ext2fs_file_write): Factored out common code and made
459 function more efficient; if writing a full block, don't
460 bother to do a read-modify-write cycle.
462 2001-05-04 Theodore Tso <tytso@valinux.com>
464 * dirblock.c (ext2fs_read_dir_block): Check for an directory
465 record length which isn't a multiple four, and treat that
466 as an invalid. Scan the directory and return an error
467 (EXT2_ET_DIR_CORRUPTED) if the directory records are
469 (ext2fs_write_dir_block): If while byte-swapping the
470 directory block, if there's an error, abort and return
471 EXT2_ET_DIR_CORRUPTED.
473 2001-05-02 Theodore Tso <tytso@valinux.com>
475 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
476 image_header field in the ext2_filsys structure
478 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
479 * inode.c (ext2fs_read_inode):
480 * rw_bitmaps.c (read_bitmaps):
481 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
483 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
484 sure the full bitmap is saved.
486 2001-05-01 Theodore Tso <tytso@valinux.com>
488 * e2image.h (struct ext2_image_hdr): Add space for the device name
491 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
492 make sure the rec_len is a multiple of 4, to prevent
493 bus-errors on architectures which care about mis-aligned
496 2001-04-25 Theodore Tso <tytso@valinux.com>
498 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
499 query the device sizes using the BLKGETSIZE ioctl.
501 2001-04-16 Theodore Tso <tytso@valinux.com>
503 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
504 before checking /etc/mtab. The EXT2_MF_READONLY flag is
505 now set from the /etc/mtab options field for all
506 filesystems, not just the root filesystem. Add debugging
507 code to make it easier to test ext2fs_check_if_mounted().
509 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
510 check; return an error if there's an attempt to create a
511 journal less than 1024 filesystem blocks.
513 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
514 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
516 2001-02-20 Theodore Tso <tytso@valinux.com>
518 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
521 * tst_byteswap.c: New function to test the byteswap functions.
522 Add to regression test suite.
524 2001-02-08 Theodore Tso <tytso@valinux.com>
526 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
528 2001-02-07 Theodore Tso <tytso@valinux.com>
530 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
531 of s_first for external devices to always be 1, since
532 jsb->s_first is always relative to the start of the
533 journal superblock. Use htonl(1) when setting s_nr_users.
535 2001-01-17 Theodore Ts'o <tytso@valinux.com>
537 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
538 device number of the filesystem (instead of the journal)
539 was being dropped into s_journal_dev.
541 2001-01-15 Theodore Ts'o <tytso@valinux.com>
543 * initialize.c (ext2fs_initialize): Add support for initializing
544 the ext2 superblock for external journal devices. This
545 basically means we don't bother to allocate any block
548 * openfs.c (ext2fs_open): Only open external journal devices if
549 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
550 ext2fs_open. When opening such devices, don't try to read
551 the block group descriptors, since they're not there.
553 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
555 * mkjournal.c: Export a new function,
556 ext2fs_create_journal_superblock(), which allocates and
557 returns a buffer containing a journal superblock. This is
558 needed by mke2fs to create an external journal. Rewrote
559 ext2fs_add_journal_device() so that it no longer creates
560 the external journal, but rather adds a filesystem to an
561 existing external journal. It handles all of the UUID
564 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
565 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
566 Changed function prototype for ext2fs_add_journal_device().
568 2001-01-14 Theodore Ts'o <tytso@valinux.com>
570 * closefs.c (ext2fs_flush): Don't write out anything beyond the
571 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
574 2001-01-12 Theodore Ts'o <tytso@valinux.com>
576 * imager.c: Fix gcc -Wall complaints and a series of bugs where
577 retval wasn't set correctly. (Thanks to Andreas Dilger
578 for pointing this out.)
580 2001-01-11 <tytso@snap.thunk.org>
582 * flushb.c (ext2fs_sync_device): New function which centralizes
583 all of the places which might try to use the BLKFLSBUF
584 or FDFLUSH ioctls (and usually failing to define them
585 since the system header files don't usually do this for
586 us, and we're trying to avoid usage of kernel include
589 2001-01-10 <tytso@snap.thunk.org>
591 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
592 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
593 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
594 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
595 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
596 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
597 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
598 ext2_ino_t, to protect applications that attempt to
599 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
600 changes ino_t(!?). So we use ext2_ino_t to avoid an
601 unexpected ABI change.
603 2001-01-05 <tytso@snap.thunk.org>
605 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
606 we may overrun allocated memory in case of a corrupted
607 filesystem (or an e2fsck test case :-) when byte-swapping
610 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
612 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
613 complaints including a missing return 0 at the end of
614 ext2fs_add_journal_device.
616 2001-01-03 <tytso@snap.thunk.org>
618 * Makefile.in: Link in libe2p when creating libext2fs as a shared
619 library, since mkjournal.c now references fsetflags().
621 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
622 Dilger's changes (with fixups) to allow on-line creation
625 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
626 EXT2_FLAG_SUPER_ONLY, which the close routines to only
627 update the superblock, and not the group descriptors.
629 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
631 * ismounted.c: add ext2fs_check_mount_point() function, which will
632 optionally return the mount point of a device if mounted
634 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
636 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
637 ext2fs_add_journal_inode()
639 2001-01-01 <tytso@snap.thunk.org>
641 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
642 source (but not binary) compatibility of some users of the
643 ext2 library. They should just simply do a global search
644 and replace of struct ext2fs_sb with struct
645 ext2_super_block, and use their own private copy of
646 ext2_fs.h if they aren't already.
648 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
649 Replace use of ext2fs_sb with ext2_super_block.
651 2000-12-31 <tytso@snap.thunk.org>
653 * ext2fs.h: Cleaned up header file by removing definitions of
654 feature flags that might not have been defined in older
655 ext2 header files. Now that we're using our own
656 include/linux/ext2fs.h header file, this can never happen.
658 * jfs_dat.h: Removed old header file which is no longer needed.
660 2000-12-13 Theodore Ts'o <tytso@valinux.com>
662 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
663 by Andreas Dilger to update the filesystem revision to
666 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
669 2000-12-09 <tytso@snap.thunk.org>
671 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
672 ext2fs_add_journal_device): Add a new argument to the APIs
673 of these function, which is a flags word. This is used to
674 allow the creation of a V1 superblock for those folks who
675 are using ext3 0.3b in production. Note, the user-land
676 interface for getting at this flag won't be documented, as
677 the V1 superblock is deprecated.
679 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
680 which creates a V2 superblock instead of a V1 superblock.
682 2000-11-21 <tytso@snap.thunk.org>
684 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
685 out by Andreas Dilger.
687 2000-11-05 <tytso@snap.thunk.org>
689 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
690 ext2_fs.h, Makefile.in: New file that has routines that
691 save ext2fs metadata to a file.
693 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
695 * e2image.h: New file which defines the file format for the ext2
696 image file. (Saved copy of ext2 metadata to a file as a
697 saving throw against worst-case damage.)
699 2000-11-01 <tytso@snap.thunk.org>
701 * inode.c (ext2fs_flush_icache): Add new function
702 ext2fs_flush_icache() which flushes the internal inode
703 cache. Applications which modify the inode table blocks
704 directly must call this function.
706 2000-10-26 <tytso@snap.thunk.org>
708 * mkjournal.c: Add #include of netinet/in.h, since Solaris
709 requires it for ntohl().
711 * ext2_io.h (io_channel_write_byte): Add new interface to allow
712 callers to write specific byte ranges. This is an
713 optional interface, which not all IO channels may
716 * unix_io.c (unix_write_byte):
717 * test_io.c (test_write_byte): Add implementation of the
720 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
721 function which writes the primary superblock. If the IO
722 channel supports writing raw bytes directly, only fields
723 which were modified are written to the disk. This makes
724 it safe(r) to use utilities like tune2fs on a mounted
727 * freefs.c (ext2fs_free): Free the original superblock if it is
730 * openfs.c (ext2fs_open): Store a copy of the original superblock
733 * ext2fs.h: Add a field to store the original superblock in the
734 ext2 context structure.
736 2000-10-24 <tytso@snap.thunk.org>
738 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
739 don't need to use llseek).
741 2000-10-24 <tytso@valinux.com>
743 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
744 creating an ext3 journal on a filesystem.
746 2000-08-21 <tytso@valinux.com>
748 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
750 2000-08-22 <tytso@valinux.com>
752 * unix_io.c: Make massive changes to support a multiple block
753 writethrough cacheing.
755 * ext2_io.h: Added flags field to the io_channel structure.
757 2000-08-19 <tytso@valinux.com>
759 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
760 provides the function ext2fs_find_block_device(). This
761 function returns the pathname to a block device, given its
764 2000-07-13 <tytso@valinux.com>
766 * Release of E2fsprogs 1.19
768 2000-07-07 Theodore Ts'o <tytso@valinux.com>
770 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
771 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
772 list of filesystem flags supported by the library.
774 2000-07-04 Theodore Ts'o <tytso@valinux.com>
776 * ext2fs.h: Update to include latest journalling additions to the
779 * dll/jump.funcs: Add new jumptable entries for
780 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
781 ext2fs_badblocks_equal.
783 * tst_badblocks.c: Update test program to test
784 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
786 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
787 writes out bad blocks list to a file.
789 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
790 changes the callback function to take two additional
791 arguments; a private blind pointer supplied by the caller,
792 and pointer to a char * containing a pointer to the
795 * badblocks.c (ext2fs_badblocks_equal): Add new function which
796 returns true if two badblocks list are equal.
798 * Makefile.in: Remove explicit link of -lc in the shared library.
799 (It shouldn't be necessary, and is harmful in some cases).
801 2000-06-10 Theodore Ts'o <tytso@valinux.com>
803 * getsize.c (main): Add debugging code under #ifdef DEBUG
805 2000-05-27 Theodore Ts'o <tytso@valinux.com>
807 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
808 earlier, so that if there's an error reading it, we can
809 more cleanly back out of the operation.
811 2000-05-25 <tytso@snap.thunk.org>
813 * getsize.c (ext2fs_get_device_size): Use open64() instead of
814 open() if it exists. Under linux, manually define the
815 ioctl for BLKGETSIZE if it isn't already defined and it's
818 * unix_io.c (unix_open): Use open64() instead of open() if it
821 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
822 available (and prototypes are defined) use it in
823 preference to llseek.
825 * Makefile: Add hack dependency rule so that parallel makes work
828 2000-05-18 Theodore Ts'o <tytso@valinux.com>
830 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
832 2000-04-03 Theodore Ts'o <tytso@valinux.com>
834 * block.c: Readibility tweak in conditionals involving
837 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
838 how to define __s64 and __u64. Turn off "compression is
839 experimental" warning if the cpp macro
840 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
842 2000-02-11 <tytso@snap.thunk.org>
844 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
845 Conditionally include Compression as a supported type if
846 ENABLE_COMPRESSION (via --enable-compression) is turned on.
848 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
850 2000-02-08 <tytso@snap.thunk.org>
852 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
853 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
854 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
855 Change to return the previous state of the bit that is
856 being marked or unmarked. For speed optimization.
858 2000-02-02 Theodore Ts'o <tytso@valinux.com>
860 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
862 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
863 needed any more; we know it will always be i_generation.
864 Add support for swapping the high bits of the uid and gid.
866 1999-11-19 <tytso@valinux.com>
868 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
869 counts if the link was successful. Patch suggested by
872 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
873 the source directory.
875 1999-11-10 <tytso@valinux.com>
877 * Release of E2fsprogs 1.18
879 1999-11-08 <tytso@valinux.com>
881 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
882 since ext2fs_badblocks_list_free was moved to freefs.c.
884 * tst_badblocks.c: Use the newer badblocks API names. Add
885 duplicate blocks to the test inputs to test dealing with
886 adding blocks which are already in the badblocks list.
888 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
889 of the list, use a shortcut O(1) operations instead of an
890 O(n) operation. (Idea suggested by David Beattie.)
892 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
893 of badblocks_list_free(), to save a procedure call.
895 1999-10-26 <tytso@valinux.com>
897 * Release of E2fsprogs 1.17
899 1999-10-26 <tytso@valinux.com>
901 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
902 seem to handle ~0UL the same way as they used to.
904 1999-10-25 <tytso@valinux.com>
906 * nt_io.c (_OpenNtName): Open the device using
907 FILE_SYNCHRONOUS_IO_NONALERT instead of
908 FILE_SYNCHRONOUS_IO_ALERT
909 (nt_open): At the end of the device open routine, unlock
910 the drive but do not dismount it.
912 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
915 1999-10-22 <tytso@valinux.com>
917 * Release of E2fsprogs 1.16
919 1999-10-22 <tytso@valinux.com>
921 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
923 * link.c (ext2fs_link): This call now uses the low three bits of
924 the flags parameter to pass the directory filetype
925 information; it will set the directory entry FILETYPE
926 information if the filesystem supports it.
928 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
929 option is set, then create the '.' and '..' entries with
930 the filetype set to EXT2_FT_DIR.
932 1999-09-24 <tytso@valinux.com>
934 * nt_io.c: New file which supports I/O under Windows NT.
936 1999-09-07 <tytso@valinux.com>
938 * ext2fs.h: Add new fields for journalling and define new
939 feature bits used by newer filesystems: IMAGIC_INODES,
940 HAS_JOURNAL, RECOVER.
942 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
943 we update the inode block count and size files so that the
944 block count field is updated correctly when we create an
947 1999-07-18 Theodore Ts'o <tytso@valinux.com>
949 * Release of E2fsprogs 1.15
951 1999-06-23 <tytso@valinux.com>
953 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
954 kernels that use i_generation instead of i_version. Patch
955 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
957 1999-06-21 <tytso@valinux.com>
959 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
960 directory entry before calling the callback function.
961 This should prevent some core dumps of insufficiently
962 paranoid callback functions.
964 1999-05-29 <tytso@rsts-11.mit.edu>
966 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
968 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
969 that we don't handle writing yet (we do). Fixed bug where
970 we weren't allocating a big enough buffer for ext2_bmap.
972 1999-05-03 <tytso@rsts-11.mit.edu>
974 * openfs.c (ext2fs_open): Check to make sure that the number of
975 blocks per group is not zero --- if so, it must be a bad
978 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
980 * Release of E2fsprogs 1.14
982 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
984 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
985 the inode number is zero; if it's zero, return
986 EXT2_ET_BAD_INODE_NUM.
988 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
990 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
991 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
994 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
996 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
997 non-Linux case to use EINVAL by default, unless it isn't
998 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
1001 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
1003 * Release of E2fsprogs 1.13
1005 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
1007 * Makefile.in: Updated dependencies.
1009 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
1011 * initialize.c (ext2fs_initialize): Make sure that we allocate
1012 enough inodes so that we can make a valid filesystem.
1014 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
1016 * rw_bitmaps.c: Fixed signed/unsigned warnings.
1018 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
1019 function declaration.
1021 * dblist.c (make_dblist): Add safety check in case the dblist
1022 pointer passed in is null (in which case, assign it to
1023 fs->dblist). Fixed some signed/unsigned warnings.
1025 * bmap.c: Make addr_per_block be of type blk_t to avoid
1026 signed/unsigned warnings.
1028 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
1029 function declaration.
1031 * get_pathname.c (get_pathname_proc): Use return value from
1032 ext2fs_get_mem, instead of checking if &gp->name is
1035 * dir_iterate.c (ext2fs_process_dir_block):
1036 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
1037 from the function declaration.
1039 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
1040 return the error directly instead of jumping to the
1041 cleanup routine, since we don't need to do any cleanup.
1043 * alloc_table.c (ext2fs_allocate_group_table): Make this
1044 function take a dgrp_t for its group argument.
1046 * ext2fs.h: Make dgrp_t an __u32 type, and make
1047 fs->desc_group_count be of type dgrp_t.
1049 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
1051 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
1052 than 10 blocks when we need to expand the size of the
1055 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1057 * Release of E2fsprogs 1.12
1059 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1061 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
1062 appropriate for all of the block group copies, so that
1063 it's clear where the beginning of the filesystem is on the
1064 disk. (For when the partition table gets scrod.)
1066 * ext2fs.h: Change the name of the feature from
1067 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
1068 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1070 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
1072 * inode.c (get_next_blockgroup): Fix bug where if
1073 get_next_blockgroup() is called early because of a missing
1074 inode table in a block group, the current_inode counter
1075 wasn't incremented correctly.
1077 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
1079 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
1080 against a completely trashed bad block inode.
1082 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
1084 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
1085 the stride length hits a bad value, we retry the block
1086 allocation starting at the beginning of the block group.
1088 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
1089 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
1090 e2_blkcnt_t to avoid collision with LFS API.
1092 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
1094 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
1095 way that avoids overflows on disk sizes greater than 4GB.
1097 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
1099 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
1100 return type for comparison functions for qsort.
1102 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
1105 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
1107 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
1110 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
1111 evade a potential problem with glibc's header files trying
1112 to spike out linux/types.h.
1114 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
1115 include the old size of the memory, which is needed for
1116 some braindamaged memory allocation systems that don't
1119 * badblocks.c (ext2fs_badblocks_list_add):
1120 bb_inode.c (clear_bad_block_proc):
1121 dblist.c (ext2fs_add_dir_block):

1124 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
1125 pass the old size of the memory to be resized to
1126 ext2fs_resize_mem().
1128 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>

1131 convention. Fix uninstall rules to take $(DESTDIR) into
1134 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
1136 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
1137 with 32 bit longs, then we need to manually define __s64
1138 and __u64, since the current kernel header files don't
1139 define these if __STRICT_ANSI__ is defined. This is a
1140 problem if we are compiling with full GCC warnings, since
1141 we do need 64 bit support.
1143 * Makefile.in (OBJS): Remove bmove.o from files to be built,
1144 since we're not using ext2fs_move_blocks() and there
1145 is some question as to its usefulness in its current
1148 * bmap.c (block_bmap): Remove unused function.
1150 * bmove.c (process_block): Fix -Wall warning.
1152 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
1154 * block.c (ext2fs_block_iterate3): Make the ref_offset field
1155 contain the offset into the inode.i_blocks array when
1156 ref_block is zero. Since we haven't done a formal
1157 release of e2fsprogs since block_iterate2 was first
1158 introduced, I removed block_iterate2, and renamed
1159 block_iterate3 to be block_iterate2.
1161 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
1162 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
1163 use of block_iterate and block_iterate2 to
1164 block_iterate2 with the new prototype for the
1165 interator function. (using blkcnt_t forr blockcount)
1167 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
1169 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
1170 s_prealloc_blocks, s_prealloc_dir_blocks). Added
1171 conditional defines of new features COMPAT_DIR_PREALLOC,
1172 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
1173 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
1174 the library to declare that we support COMPAT_DIR_PREALLOC,
1175 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1177 * fileio.c: Rename function ext2fs_file_llseek to be
1178 ext2fs_file_lseek, which is more accurate.
1180 * block.c: Add new function ext2fs_block_iterate3 which calls
1181 the iterator function with the blockcount argument of
1182 type blkcnt_t. This version of the function is
1183 allowed to handle large files; the other fucntions are
1186 * ext2fs.h: Add new type blkcnt_t
1188 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1190 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1191 field wasn't getting correctly incremented for sparse
1192 files when the indirect or doubly-indirect block
1193 specified in the inode was zero.
1195 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1197 * unlink.c (unlink_proc):
1198 * lookup.c (lookup_proc):
1199 * link.c (link_proc):
1200 * get_pathname.c (get_pathname_proc):
1201 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1202 from dirent->name_len, so it can be used for other
1205 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1206 and indicate that we have support for this incompatible

1216 number of directories when the block group information is
1219 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1221 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1222 inode table is missing so that we catch the case where the
1223 first block group is missing.
1225 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1228 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1230 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1232 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1234 * test_io.c (test_flush): Add a debugging printf when the flush
1237 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1238 read in, return right away.
1240 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1242 * bitops.h: Don't try to do i386 inline asm functions if the
1245 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1246 instead of linux/types.h, and e2_bitops.h instead of
1249 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1252 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1254 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1255 so that we don't need to call get_next_blockgroup() the
1256 first time around. Saves a bit of time, and prevents us
1257 from needing to assign -1 to current_group (which is an
1260 * icount.c (insert_icount_el): Cast the estimated number of inodes
1261 from a float to an ino_t.

1273 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1274 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
1275 defined, then assume all of the
1276 ext2-specific header files are in a flat directory.
1278 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1279 all assignments from void * to be compatible with C++.

1300 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1302 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1303 paranoid about validating the directory counts from the
1304 block group information.
1306 * all files: Don't include stdlib.h anymore; include it in
1307 ext2_fs.h, since that file requires stdlib.h
1309 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1311 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1312 bitmap is loaded, and return an error if it is not.
1313 (expand_dir_proc): Only use ext2fs_write_dir_block when

1363 physical block number.
1365 * fileio.c: New file which implements simple file reading and
1368 * alloc.c (ext2fs_alloc_block): New function which allocates a
1369 block, zeros it, and updates the filesystem accounting

1428 * io.h: Change the prototype of ext2fs_llseek() to use int's
1429 instead of unsigned int's.
1431 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1432 to make life easer for GNU Libc 2.
1434 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1435 filesystem has its bitmaps stored as 32-bit words with bit
1436 0 as the LSB of each word. Thus a bitmap with only bit 0
1437 set would be, as a string of bytes, 00 00 00 01 00 ... To
1438 cope with this, we byte-reverse each word of a bitmap if
1439 we have a big-endian filesystem, that is, if we are *not*
1440 byte-swapping other word-sized numbers.

1525 * unix_io.c (unix_flush): Make the io_channel flush function do a
1526 fsync to flush the kernel buffers to disk.
1528 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1560 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1561 ext2fs_badblocks_list_test would test the list (and exceed
1562 array boundaries) if there were no bad blocks on the bad
1563 blocks list. (Showed up when user tried: mke2fs -c -b 4096).

1606 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
1609 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1610 badblocks structure.
1612 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1616 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1618 (unix_close, test_close): Decrement the refcount and only
1619 close the io_channel if the refcount goes to 0.
1621 * io.h: Add refcount to the io_channel structure. Add new macro
1622 interface io_channel_bumpcount() to bump the refcount.
1624 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1626 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1627 cache in the filesystem handle, instead of the inode cache
1628 in a static variable.
1630 * freefs.c: Added static function to free the inode cache (called by
1633 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1635 * ext2fs.h: Added pointer to the inode_cache structure.
1637 * block.c (block_iterate_ind, block_iterate_dind,
1638 block_iterate_tind): If there are holes in the indirect,
1639 doubly indirect, or triply indirect blocks, increment the
1640 block count field automatically.
1642 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1644 * Release of E2fsprogs version 1.09
1646 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1648 * version.c (ext2fs_parse_version_string): Check the passed in
1649 version string (instead of the hard-coded one).
1651 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1652 greater filesystem size, clamp it to prevent allocating a
1653 block or inode bitmap beyond the filesystem.
1655 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1656 overhead calculation was accidentally removed.
1658 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1660 * Release of E2fsprogs version 1.08
1662 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1664 * dblist.c (ext2fs_set_dir_block): New function which sets the
1665 block of a dblist entry, given the directory inode and
1668 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1670 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1671 inode bitmaps at staggered locations across the block
1672 groups, to avoid concentrating the bitmaps on a small
1673 number of disks when using striped RAID arrays.
1675 * initialize.c (ext2fs_initialize): By default, choose the maximum
1676 possible number of blocks per group (based on the size of
1677 the bitmaps in the blocksize).
1679 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1681 * initialize.c (ext2fs_initialize): Add support for
1682 EXT2_COMPAT_SPARSE_SUPER feature.
1684 * closefs.c (ext2fs_bg_has_super): New function to determine
1685 whether or a particular block group should have a
1686 superblock and block group descriptor. Used for the
1687 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1688 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1689 or not the superblock should be written out for the block
1692 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1693 for sparse duplicate superblocks.
1695 * version.c (ext2fs_get_library_version): New function which
1696 returns the library version.
1698 * version.c (ext2fs_parse_version_string): New function which
1699 parses a version string and returns a version number,
1700 so application programs can compare version numbers as
1703 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1705 * icount.c (ext2fs_create_icount): Change function so that it also
1706 takes a new argument which contains a "hint" icount
1707 structure. This "hint" icount allows the create function
1708 to set up the sorted list in advance. This reduces
1709 significantly the amount of data moving needed to insert
1710 these inodes into the list later.
1712 * icount.c (ext2fs_icount_validate): New function which validates
1713 that the icount structure's rep invariant.
1715 * icount.c (get_icount_el): Completely revamped implementation
1716 to subsume put_icount_el(). Put_icount_el() used to
1717 use an O(N) implementation to insert in the middle
1718 of the icount list. It now uses a O(ln N) to search
1719 for where the icount should be inserted, and then uses
1720 a memcpy to move the list down (instead of a for loop).
1722 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1723 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1724 to see if the inode is within bounds; if it isn't, return
1727 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1728 when a bad inode number is passed to test_generic_bitmap
1729 to be EXT2FS_TEST_ERROR instead of the wrong
1730 EXT2FS_UNMARK_ERROR.
1732 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1734 * Release of E2fsprogs version 1.07
1736 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1738 * Makefile.in (ELF_VERSION): Change version to be 2.2
1740 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1742 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1743 ext2fs_fast_test_block_bitmap_range().
1745 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1746 ext2fs_test_block_bitmap_range: New inline functions which
1747 test to see whether a contiguous range of blocks is
1750 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1752 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1753 use ext2fs_badblocks_* instead of badblocks_*
1755 * bb_compat.c: New file which translates between old badblocks_*()
1756 names to ext2fs_badblocks_*()
1758 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1759 link.c (since e2fsck doesn't use ext2fs_unlink()).
1761 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1762 bitmap resizing routine moved from bitmaps.c, since e2fsck
1763 doesn't need to use this function.
1765 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1766 since e2fsck only needs ext2fs_lookup.
1768 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1770 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1771 already set; this is needed so that programs like dump
1772 which use the inode scan functions will deal with
1773 filesystems that have bad blocks in the inode table.
1775 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1777 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1778 Moved to ext2fsP.h, since it doesn't need to be part of
1779 the public interface.
1781 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1783 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1785 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1786 directory block list abstraction. (Code moved from
1789 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1790 to inode.c (since no one else should be peeking inside it!)
1792 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1794 * openfs.c (ext2fs_open): Check the feature set in the ext2
1795 superblock, and refuse to open filesystems if they contain
1796 incompatible features. (Can be overriden with the
1799 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1801 * block.c (ext2fs_block_iterate2): Added new function
1802 ext2fs_block_iterate2 which changes the function
1803 signature of the callback function to include the
1804 referencing block and offset.
1806 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1807 ext2fs_inode_scan_goto_blockgroup which allows an
1808 application to jump to a particular block group while
1809 doing an inode scan.
1811 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1813 * dirblock.c: Include string.h, since we use memcpy().
1815 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1817 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1818 a long not an int; this doesn't matter on i386 machines,
1819 but it does on Alpha's.
1821 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1823 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1824 table pointer is NULL, then return an error indicating
1825 that the inode table is missing.
1826 (get_next_blockgroup, get_next_blocks,
1827 ext2fs_get_next_inode): Don't treat a missing inode table
1828 as permanent error. Return MISSING_INODE_TABLE, but as an
1829 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1831 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1832 ext2fs_write_inode_bitmap): If the inode or block bitmap
1833 block is zero, then don't write out the inode or block
1834 bitmap. The idea here is to avoid stomping on the
1836 (read_bitmaps): If the inode or block bitmap block is
1837 zero, then fill in that portion of the inode or block
1838 bitmap with all zeros.
1840 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1841 blocks in inode table when the inode table size is
1842 non-standard (and can therefore span blocks).
1844 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1846 * alloc.c (ext2fs_new_block): Fix fencepost error in
1847 ext2fs_new_block; make sure we don't try to allocate the
1848 first block beyond the end of the filesystem.
1850 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1852 * inode.c (check_for_inode_bad_blocks): New function called by
1853 get_next_blocks() to avoid reading in bad blocks marked in
1854 fs->badblocks. Inodes located in bad blocks are returned
1855 by ext2fs_get_next_inode() returns the error code
1856 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1858 * alloc_tables.c (ext2fs_allocate_tables): New function which
1859 performs the part of mke2fs's job of allocating the
1862 * test_io.c (test_close): IO manager which is used for testing
1865 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1867 * inode.c (ext2fs_get_next_inode): Separate out the function of
1868 setting up for a new block group to get_next_blockgroup().
1869 Separate out the function of reading in blocks of the
1870 inode table to get_next_blocks().
1872 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1874 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1875 blocks to the badblock list in sorted order. This allows
1876 badblocks_list_test to be coded using a binary search for
1879 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1881 * Release of E2fsprogs version 1.06
1883 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1885 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1886 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1889 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1890 set, then only write out the master superblock.
1892 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1894 * block.c (ext2fs_block_iterate): Fixed bug which caused
1895 block_iterate to fail to handle HURD created filesystems;
1896 it tested the inode translator field before the inode was
1899 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1901 * initialize.c (ext2fs_initialize): Make sure the description for
1902 the inode bitmap is set correctly.

1908 * Release of E2fsprogs version 1.05
1910 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1912 * initialize.c: Override the kernel's idea of default
1913 checkinterval from 0 (never) to 180 days.

1927 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
1930 * namei.c (ext2fs_follow_link): New function.
1931 (ext2fs_namei): Extended to have support for chasing
1932 symbolic links. ext2fs_namei() still returns an inode
1933 which is a symbolic link. Symbolic links are only chased
1934 while resolving the containing directory. To chase
1935 symbolic links of the final result, use
1936 ext2fs_follow_link().
1938 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1940 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1942 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines

1947 * initialize.c (ext2fs_initialize): On systems where the byte
1948 order is not i386 compatible, set the swap_byte flag.
1950 * inode.c (inocpy_with_swap): Check to see if inode contains a
1951 fast symlink before swapping the inode block fields. This
1952 required adding a new argument to inocpy_with_swap to
1953 determine whether the mode field is in host order or not.
1955 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1957 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1958 the sparc, if EXT2_STD_BITOPS set, use the standard
1959 i386-compatible bitmask operations, instead on the
1960 non-standard native bitmask operators.
1962 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1964 * block.c (ext2fs_block_iterate): Cause block iterator to return
1965 the HURD translator block (along with everything else).
1966 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1967 iterator, then don't return any meta data blocks
1968 (including the HURD translator).
1970 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1972 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1974 * uuid.c: New file, containing UUID utility functions.
1976 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1978 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1980 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1982 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1984 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1986 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1987 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1988 that's a basic value that must be correct for the rest of
1989 the library to work.
1991 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1994 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2004 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
2005 Change the m68k bit numbering for bitmasks to match with
2006 the bit numbering used by all other ext2 implementations.
2008 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>

2043 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
2044 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
2045 to avoid conflicts with with kernel include files. Also
2046 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
2049 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
2051 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c

2093 * getsize.c (ext2fs_get_device_size): New function that determins
2094 the size of a device. Used by mke2fs and e2fsck.
2096 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
2098 * Makefile.in (install): Install static libraries in $(ulibdir)
2099 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
2101 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
2103 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
2104 Move these functions to freefs.c.
2106 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
2107 descriptors shadow memory to keep purify quiet. (This
2108 also has the nice benefit that the unused portion of the
2109 shadow descriptors are zeroed out.)
2111 * dirblock.c (ext2fs_write_dir_block): We need to use
2112 dirent->rec_len *before* it's byteswapped to find the
2113 location of the next directory structure!
2115 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
2116 cause ext2fs_new_inode to loop infinitely if we're trying
2117 to allocate an inode in group #0 and there are no free
2118 inodes at all in the system.
2120 * closefs.c: #include <errno.h> if it exists.
2122 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2124 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for
2125 BLOCK_FLAG_APPEND. Added documentation for the block
2128 Sat Aug 5 11:44:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2130 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
2131 installation directories correctly.
2133 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
2135 * namei.c (process_dir_block):
2136 * mkdir.c (ext2fs_mkdir):
2137 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
2138 to read/write the directory block.
2140 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
2141 file containing functions for reading and writing
2142 directory blocks (byte swapping if necesssary)
2144 * block.c (block_iterate_ind, block_iterate_dind,
2145 block_iterate_tind): Byte swap the block addresses if
2146 EXT2_SWAP_BYTES is set (and swap them back before writing
2149 * inode.c (inocpy_with_swap): New function.
2150 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
2151 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
2153 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
2154 the superblock and group descriptors before writing it out.
2156 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
2157 then set the EXT2_SWAP_BYTES and byte-swap the superblock
2158 and group descriptors.
2160 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
2161 to desp ext2 filesystem structures.
2163 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
2164 supplied by Pete A. Zaitcev so that the C language
2165 versions of these functions are more portable. They will
2166 now work on both little and big endian systems, and the
2167 assumption that 32-bit integers are used is gone.
2169 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
2170 doing byte swapping.
2172 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
2173 byte swapping should take place.
2175 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
2177 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
2178 ext2fs_compare_inode_bitmap_end): Added new file
2179 containing routines to compare bitmaps.
2181 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
2182 Added new error codes.
2184 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
2186 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2187 if the magic number is correct, it will be allocated.
2189 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2191 * block.c (block_iterate_ind, block_iterate_dind,
2192 block_iterate_tind): Don't recompute block_nr each loop;
2193 just increment it! Factor check of BLOCK_FLAG_APPEND out
2194 of the loop. Factor mask of BLOCK_CHANGED into changed
2195 variable out of the loop. (block_iterate_ind, in
2196 particular, gets called a lot, so every little
2197 optimization helps.)
2199 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2201 * block.c (block_iterate_ind, block_iterate_dind,
2202 block_iterate_tind): Precompute limit of loop to speed up
2203 block_iterate_ind and company.
2205 * bitops.h (ext2fs_fast_mark_block_bitmap,
2206 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
2207 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2208 ext2fs_fast_test_inode_bitmap): Add fast version of these
2209 functions, which don't do range checking.
2211 * bitops.h (ext2fs_get_block_bitmap_start,
2212 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2213 ext2fs_get_inode_bitmap_end): Add new accessor functions
2214 which return the start and end points of the bitmaps.
2216 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2218 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2219 instead of llseek. The errno if the offset is too large
2220 and lseek is not supported should be EINVAL, not -EINVAL.
2222 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2224 * Makefile.in: Added support for ELF shared libraries.
2225 Fixed typos in the compilation rules.
2226 (distclean): Added Makefile.
2228 * llseek.c (llseek): New function, if llseek() does not exist in the
2230 (ext2_llseek): Changed to call llseek().
2232 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2234 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
2236 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2238 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2240 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2241 the S_*, which are normally defined in <sys/stat.h>. This
2242 allows us to compile e2fsprogs on a non-Linux system,
2243 which may have a different value for S_IFDIR.
2245 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2247 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2248 this is a user-mode application!
2250 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2252 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2253 __linux__ so that non-linux systems won't see it.
2255 * alloc.c: Include <errno.h> if possible.
2256 * badblocks.c: Ditto.
2257 * bb_inode.c: Ditto.
2260 * expanddir.c: Ditto.
2261 * get_pathname.c: Ditto.
2262 * initialize.c: Ditto.
2269 * rw_bitmaps.c: Ditto.
2272 * Makefile.in: Rewritten to conform to GNU coding standards and
2273 support separate compilation directories.
2275 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2277 * initialize.c (ext2fs_initialize): Don't allow more than one
2278 bitmaps's worth of inodes in a group.
2280 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2282 * llseek.c (ext2_llseek): Added error checking to the llseek()
2283 compat code to protect against overflow. This only
2284 applies to 1.0 and early 1.1 kernels, which don't support
2285 the llseek() system call.
2287 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2289 * unix_io.c (unix_open): Initialize the read_error and write_error
2290 io_channel pointers to be null.
2292 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2293 found, clear it but don't try to update the filesystem
2294 accounting information, since that's hopeless anyway.
2296 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2297 bloblock_iterate_tind): Check to see if the indirect blocks are
2298 valid before trying to read them.
2300 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
2301 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2303 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2304 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2305 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2306 illegal block or inode number is passed in, return instead
2307 of trying to test, set, or clear the bit.
2309 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2311 * Makefile: Added a dummy install target in case shared libraries
2314 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2316 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
2317 the real last block of the bitmap should be calculated.
2319 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
2321 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
2322 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
2323 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
2324 ext2fs_free_block_bitmap): Add magic number checking for
2325 the inode and block bitmaps.
2327 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2328 magic number for a block bitmap instead of an inode bitmap.
2330 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
2331 magic number checking for the inode_scan structure.
2333 * badblocks.c (badblocks_list_free, badblocks_list_add,
2334 badblocks_list_test, badblocks_list_iterate_begin,
2335 badblocks_list_iterate, badblocks_list_iterate_end): Add
2336 magic number checking for the badblocks_list and
2337 badblocks_iterate structures.
2339 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
2340 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
2341 unix_write_blk, unix_flush): Add magic number checking
2342 both for io_channel structure and unix_private_data
2345 * openfs.c (ext2fs_open): Add check for io_manager structure's
2348 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2349 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2350 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2351 * read_bb.c (ext2fs_read_bb_inode):
2352 * read_bb_file.c (ext2fs_read_bb_FILE):
2353 * newdir.c (ext2fs_new_dir_block):
2354 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
2355 * link.c (ext2fs_link, ext2fs_unlink):
2356 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

2361 * block.c (ext2fs_block_iterate):
2362 * bitmaps.c (ext2fs_allocate_inode_bitmap,
2363 ext2fs_allocate_block_bitmap):
2364 * bb_inode.c (ext2fs_update_bb_inode):
2365 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
2366 * check_desc.c (ext2fs_check_desc):
2367 * closefs.c (ext2fs_close, ext2fs_flush):
2368 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2373 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2374 openfs.c into its own file.
2376 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2377 structure magic numbers.
2379 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2380 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2381 someone uses the -b option to specify the use of the backup
2382 superblock --- this usually means that the main superblock is
2386 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2387 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2388 revision level to the superblock.
2390 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2397 * initialize.c: Completely revamped the inode and block bitmap
2398 structures, so that they can be better chance of being extensible
2399 in a shared library. They are now their own type, instead of
2400 being a char *. Also, the function signatures of
2401 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2402 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2403 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2404 changed to eliminate the ext2_filsys argument, since it is no
2407 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2409 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2410 system call if available.
2412 * llseek.c: new file. This is the stub calling the llseek system
2413 call which allows supports for 2GB+ file systems.
2415 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2416 the creator operating system.
2418 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2420 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2421 the group descriptor statistics in addition to everything else.
2422 This relieves mke2fs of the responsibility of doing it.
2424 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2425 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2426 not the generic C function equivalents should be included or not.
2428 * openfs.c (ext2fs_open): If a superblock is specified, then use
2429 the backup group descriptors that go along with this superblock,
2430 instead of using the primary group descriptors. This allows
2431 e2fsck to recover filesystems where the primary group descriptors
