22 * openfs.c (ext2fs_open2): We now set EXT2_FLAG_MASTER_SB_ONLY
23 when we open a filesystem. Applications that want to
24 write changes to the backup superblocks need to explicitly
27 2007-05-31 Theodore Tso <tytso@mit.edu>
29 * tst_super_size.c (main): Add sanity check to make sure the
30 supersize structure is 1024 bytes.

61 * ext2_fs.h, swapfs.c (ext2fs_swap_inode_full): Rename the
62 l_i_reserved1 field to be l_i_version (to be used for the
63 high 32 bits of the 64-bit inode version number).
65 2007-04-18 Theodore Tso <tytso@mit.edu>
67 * getsize.c (ext2fs_get_device_size): Make sure we don't leak a

107 * imager.c (ext2fs_image_inode_write), inode.c
108 (ext2fs_write_inode_full): Fix memory leak on error return
109 (when the inode table is missing).
111 2006-11-30 Theodore Tso <tytso@mit.edu>
113 * ext2_fs.h (struct ext4_group_desc): Fix missing bg_pad which
114 made the structure too small.
116 2006-11-14 Theodore Tso <tytso@mit.edu>
118 * namei.c (open_namei): Rename internal variable basename to
119 base_name to prevent gcc -Wall complaints.

124 * ext2_ext_attr.h (EXT2_EXT_ATTR_PAD): Make unsigned to fix gcc
127 * bitops.h (ext2fs_test_bit): Add missing const to fix gcc -Wall
130 * ext2fs.h (ext2fs_get_mem, ext2fs_free_mem): Avoid type punning
131 which causes problems on the ARM processor. (Addresses
134 2006-11-12 Theodore Tso <tytso@mit.edu>
136 * ext2_fs.h (EXT2_FLAG_SOFTSUPP_FEATURES), openfs.c
137 (ext2fs_open2): Add flag which indicates that it's OK to
138 open a filesystem which has features which are only
139 partially supported by e2fsprogs.
141 * ext3_extents.h, ext2fs.h: Check in ext4 extent headers into the
142 source tree, in preparation for adding full extent support.
144 * unix_io.c (unix_flush): Allow offsets greater than 2G.
145 (Addresses SourceForge Bug #1547922)
147 2006-11-11 Theodore Tso <tytso@mit.edu>
149 * dirhash.c (str2hashbuf, ext2fs_dirhash): Add support for
150 calculating the unsigned version of the directory hash.
152 * initialize.c (ext2fs_initialize): Set the dirhash
153 signed/unsigned hint in s_flags.
155 * swapfs.c (ext2fs_swap_super): Byte swap the s_flags superblock
158 * ext2_fs.h: Define a new superblock field, s_flags, which is used
159 to store a signed vs. unsigned dirhash hint. Define new
160 HTREE hash algorithm numbers to pass to userspace if the
161 unsigned algorithm are required.
163 * swapfs.c (ext2fs_swap_super):
164 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE,
165 which adds s_min_extra_isize and s_want_extra_isize fields
166 to superblock, which allow specifying the minimum and
167 desired i_extra_isize fields in large inodes
168 (for nsec+epoch timestamps, potential other uses).
169 Needs RO_COMPAT flag handling, needs e2fsck support,
170 patch complete, little testing.
172 * swapfs.c (ext2fs_swap_super):
173 ext2_fs.h: Add definition of EXT4_FEATURE_INCOMPAT_64BIT,
174 which adds supports for 64-bit block count fields in the
175 superblock (s_blocks_count_hi, s_free_blocks_count_hi),
176 large group descriptors (s_desc_size), extents with high
177 16 bits (ee_start_hi, ei_leaf_hi), inode ACL (i_file_acl_hi)
179 * ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_DIR_NLINK,
180 which allow directories to have > 65000 subdirectories
181 (i_nlinks) by setting i_nlinks = 1 for such directories.
182 RO_COMPAT protects old filesystems from unlinking such
183 directories incorrectly and losing all files therein.
185 * swapfs.c (ext2fs_swap_group_desc):
186 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
187 which adds a crc16 checksum in the group descriptor,
188 (s_uuid[16] | __u32 group | ext3_group_desc
189 (excluding gd_checksum itself)). This allows the kernel
190 to more safely manage UNINIT groups. Also adds an
191 bg_itable_unsued which indicates how many inodes are
192 uninitialized in the block group.
194 * swapfs.c (ext2fs_swap_inode_full):
195 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_HUGE_FILE,
196 which changes i_blocks to be in units of s_blocksize units
197 instead of 512-byte sectors, use l_i_frag and l_i_fsize as
200 2006-10-02 Eric Sandeen <esandeen@sandeen.net>
202 * getsize.c (ext2fs_get_device_size): Check to make sure that the
203 number of blocks doesn't overflow the retblocks return
204 parameter for regular files using stat64().
206 2006-10-01 Theodore Tso <tytso@mit.edu>
208 * bitops.h (ext2fs_swab32): Only include ext2fs_swab32() if
209 EXT2FS_ENABLE_SWAPFS is defined.
211 2006-08-30 Eric Sandeen <esandeen@redhat.com>
213 * initialize.c (ext2fs_initialize): Make sure inode count does
214 not overflow 32 bits.
216 2006-08-30 Eric Sandeen <esandeen@redhat.com>
218 * alloc_tables.c (ext2fs_allocate_group_table):
219 * check_desc.c (ext2fs_check_desc):
220 Use new inlines to calculate group first & last blocks.
222 Create new inlines to calculate first/last group blocks.
224 2006-08-30 Eric Sandeen <esandeen@redhat.com>
226 * bmove.c (process_block):
228 * icount.c (ext2fs_create_icount2, insert_icount_el):
229 * tst_badblocks.c (print_list, validate_test_seq, do_test_seq):
230 * tst_badblocks.c (invalid_proc):
231 * tst_getsize.c (main):
232 * tst_iscan.c (check_map):
233 * unix_io.c (raw_read_blk, unix_read_blk):

238 * closefs.c (write_backup_super):
239 * initialize.c (ext2fs_initialize): Remove unused variables.
241 2006-08-30 Eric Sandeen <esandeen@redhat.com>
243 * check_desc.c (ext2fs_check_desc): avoid overflows when iterating
244 over group descriptors on very large filesystems.
246 2006-08-30 Theodore Tso <tytso@mit.edu>
248 * bitmaps.c (ext2fs_set_bitmap_padding): Fix potential overflow
249 problems when the number of blocks is close to 2**31.
251 * ext2fs.h (ext2fs_div_ceil): Add new function which safely
252 calculates an integer division where the result is always
253 rounded up while avoiding overflow errors.
255 * initialize.c (calc_reserved_gdt_blocks, ext2fs_initialize):
256 * openfs.c (ext2fs_open2): Use ext2fs_div_ceil() instead of a
257 using an open-coded expression which was subject to
260 2006-08-06 Andreas Dilger <adilger@clusterfs.com>
262 * bitops.h (ext2fs_cpu_to_le32, ext2fs_le64_to_cpu,
263 ext2fs_swab64): Add 64-bit byte swapping functions
265 2006-08-05 Theodore Tso <tytso@mit.edu>
267 * ext2_fs.h (EXT4_EXTENTS_FL): Rename EXT3_EXTENTS_FL to
268 EXT4_EXTENTS_FL, and add EXT4_EXTENTS_FL to user visible
271 2006-07-15 Theodore Tso <tytso@mit.edu>
273 * ext2fs.h: Remove unneeded #ifdef since EXT2_DYNAMIC_REV is
274 always defined in the e2fsprogs-provided ext2_fs.h
276 2006-05-21 Theodore Tso <tytso@mit.edu>
278 * openfs.c (ext2fs_open2): Fix type warning problem with sizeof()
280 2006-05-12 Theodore Tso <tytso@mit.edu>
282 * alloc_tables.c (ext2fs_allocate_group_table): When allocating
283 space for the RAID filesystems with the stride parameter,
284 place each portion of the group's inode table right up
285 after the superblock (if present) in order to minimize
286 fragmentation of the freespace.
288 2006-05-08 Theodore Tso <tytso@mit.edu>
290 * rw_bitmaps.c (write_bitmaps, read_bitmaps): Added support for
291 lazy blockgroups. If a block group has flags indicating
292 that its block or inode data structures have not been
293 initialized, skip reading or writing that portion of the
296 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode_full): When
297 scanning a filesystem with lazy blockgroups, skip
298 uninitialized portions of the inode table when iterating
299 over the block group.
301 * swapfs.c (ext2fs_swap_group_desc): Byte swap the bg_flags field.
303 * ext2fs.h: Define the a new internal flag, EXT2_SF_DO_LAZY, so
304 that the inode interator knows compat_lazy_bg feature is
305 enabled. Declare that this version of e2fsprogs supports
306 the EXT2_FEATURE_COMPAY_LAZY_BG feature.
308 * ext2_fs.h (struct ext2_group_desc): Use the bg_pad field for
309 bg_flags, and define the flags EXT2_BG_INODE_UNINIT and
310 EXT2_BG_BLOCK_UNINIT. These flags are only honored if
311 EXT2_FEATURE_COMPAT_LAZY_BG feature is enabled (also
314 2006-04-23 Theodore Ts'o <tytso@mit.edu>
316 * rw_bitmaps.c (write_bitmaps, ext2fs_write_inode_bitmap,
317 ext2fs_write_block_bitmap, ext2fs_write_bitmaps): Reduce
318 disk seeks by writing the inode and block bitmaps in an
321 2006-04-09 Theodore Ts'o <tytso@mit.edu>
323 * ext2_types.h.in, Makefile.in, tst_types.c: Use the asm_types.h
324 file to define the __[us]{8,16,32,64} types. Add a
325 tst_types program to make sure the types are correct.
327 2006-04-04 Theodore Ts'o <tytso@mit.edu>
329 * mkjournal.c (ext2fs_add_journal_inode): If the filesystem is
330 opened in exclusive mode, then device will be busy by
331 definition, so don't return -EBUSY. This caused mke2fs -j
332 to fail on the 1.39-WIP (29-Mar-2006) release. (Addresses
335 2006-03-29 Theodore Ts'o <tytso@mit.edu>
337 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit): Fix the constraints
338 so that GCC knows that the ext2fs_set/clear_bit reads and
341 2006-03-25 Theodore Ts'o <tytso@mit.edu>
343 * Makefile.in: Check the bitfield operations much more carefully,
344 and arrange to have tst_bitops run from "make check"
346 * tst_bitops.c: Enahce tst_bitops program so that it is much more
347 thorough in testing bit optations.
349 * bitops.h: Add new functions ext2fs_fast_set_bit() and
350 ext2fs_fast_clear_bit() and make the x86 functions 32-bit
351 clear. Change the fast inode and block mark/unmark
352 functions to use ext2fs_fast_set/get_bit()
354 2006-03-18 Theodore Ts'o <tytso@mit.edu>
356 * ext2fs.h (EXT2_FLAG_EXCLUSIVE): Define new flag which requests
357 that the io_channel be opened in exclusive mode.
359 * openfs.c (ext2fs_open2), initialize.c (ext2fs_initialize): If
360 EXT2_FLAG_EXCLUSIVE is passed to ext2fs_open or
361 ext2fs_initialize, then pass IO_FLAG_EXCLUSIVE to the
362 io_channel open routine.
364 * ext2_io.h (IO_FLAG_EXCLUSIVE), unix_io.c (unix_open): Add new
365 io_channel open flag, IO_FLAG_EXCLUSIVE, which requests
366 that the device be opened in exclusive (O_EXCL) mode.
368 * ext2fs.h: Fix documentation so that BLOCK_FLAG_TRAVERSE is
369 BLOCK_FLAG_DEPTH_TRAVERSE. (Addresses Debian Bug #351268)
371 2006-03-17 Theodore Ts'o <tytso@mit.edu>
373 * initialize.c (calc_reserved_gdt_blocks): Fix a signed vs
374 unsigned problem which caused mke2fs -O resize_inode to
375 bomb out on large filesystems. (Addresses Debian Bug
378 * ext2_fs.h (EXT2_IOC_GETVERSION_NEW, EXT2_IOC_SETVERSION_NEW,
379 EXT2_IOC_GROUP_EXTEND, EXT2_IOC_GROUP_ADD): Add ioctl
382 2005-12-10 Theodore Ts'o <tytso@mit.edu>
384 * Makefile.in: Add a dependency to make sure that the
385 subdirectories are created before creating all of the
388 2005-12-10 Theodore Ts'o <tytso@mit.edu>
390 * res_gdt.c (ext2fs_create_resize_inode): Fix type-punning warning.
392 * read_bb_file.c (ext2fs_read_bb_FILE): Use a data structure
393 instead of stuffing a function pointer dirctly into a void
394 pointer, since that isn't portable.
396 * mkjournal.c (ext2fs_add_journal_inode): Fix possiblely
397 uninitialized use of variable warning.
399 * initialize.c (calc_reserved_gdt_blocks): Fix signed vs. unsigned
402 * ext2fs.h: Make the type of the 'now' field to be time_t to avoid
403 gcc -Wall complaints.
405 * bitops.h (ext2fs_find_first_bit_set): Fix signed vs unsigned
408 * tst_badblocks.c (file_test_invalid): Add test which confirms
409 proper detection of invalid block numbers in
410 ext2fs_read_bb_FILE().
412 2005-11-20 Theodore Ts'o <tytso@mit.edu>
414 * bitops.h: We no longer have the sparc assembly code in the
415 header file any more, so we shouldn't set
416 _EXT2_HAVE_AS_BITOPS_. This would break compiles on the
417 sparc architectures when using gcc.
419 2005-11-13 Theodore Ts'o <tytso@mit.edu>
421 * ext2fs.h: Add #include <string.h> since the inline functions use
422 memcpy(). (Addresses Sourceforge Bug #1251062)
424 2005-11-09 Theodore Ts'o <tytso@mit.edu>
426 * Fix a bug when writing an external journal device on an big
427 endian machine (such as a S/390), where when the number of
428 block groups is zero, we never end up writing out the
429 primary superblock at all.
431 2005-09-24 Theodore Ts'o <tytso@mit.edu>
433 * ext2fs.h, bb_inode.c, closefs.c, initialize.c, mkdir.c,
434 mkjournal.c, res_gdt.c: If fs->now is non-zero, use that
435 as the time instead of the system time when setting
436 various filesystem fields (last modified time, last write
439 2005-08-28 Matthias Andree <matthias.andree@gmx.de>
441 * Fix compiler warnings about missing memcpy prototypes.
443 2005-07-25 Theodore Ts'o <tytso@mit.edu>
445 * test_io.c (safe_getenv): Pass in zero to the unusued arguments
446 of prctl(PR_GET_DUMPABLE) to avoid false positives from
449 2005-07-19 Theodore Ts'o <tytso@mit.edu>
451 * mkjournal.c (ext2fs_add_journal_inode): Check for the case where
452 the filesystem is apparently not mounted, but the device
453 is still busy. This can happen when the luser doesn't
454 bother to mount /proc and has a bogus /etc/mtab, but still
455 wants to mount the filesystem before using tune2fs(?!?).
456 Add a safety check to save him from his own stupidity, at
457 least on 2.6 kernels. (Addresses Debian Bug #319002)
459 2005-07-09 Andreas Dilger <adilger@clusterfs.com>
461 * getsize.c (ext2fs_get_device_size): Use fstat/fstat64 to get
462 size of regular files. Fix file descriptor leaks in error
465 2006-06-30 Theodore Ts'o <tytso@mit.edu>
467 * Release of E2fsprogs 1.38
469 2005-06-30 Theodore Ts'o <tytso@mit.edu>
471 * bitops.h, bitops.c (ext2fs_set_bit, ext2fs_clear_bit,
472 ext2fs_test_bit): Change these function prototypes to be
473 unsigned int's. Negative bit numbers were never allowed
474 (and never made any sense), so this should be a safe
475 change. This is needed to allow safe use of block numbers
476 greater than or equal to 2**31.
478 2005-06-27 Stephen Tweedie <sct@redhat.com>
480 * ext2fs.h (ext2fs_resize_mem): Fix C99 strict type aliasing
481 problems. Addresses Red Hat Bugzilla #161183.
483 2005-06-19 Theodore Ts'o <tytso@mit.edu>
485 * getsectsize.c (BLKSSZGET): Clean up test for when to manually
486 define the BLKSSZGET ioctl.
488 2005-05-29 Theodore Ts'o <tytso@mit.edu>
490 * ismounted.c (ext2fs_check_mount_point): Add test to see if the
491 device appears to be busy; this only works on Linux 2.6+
492 systems, but provides some additional bullet-proofing in
495 2005-05-08 Theodore Ts'o <tytso@mit.edu>
497 * test_io.c (safe_getenv): Fix bug so it would fetch the right
498 environment variable.
500 2005-04-09 Theodore Ts'o <tytso@mit.edu>
502 * inode.c (ext2fs_write_new_inode),
503 ind_block.c (ext2fs_read_ind_block): Add missing return
504 value in error return case. (Otherwise we return garbage
505 instead of the error code.)
507 2005-03-31 Theodore Ts'o <tytso@mit.edu>
509 * test_io.c (test_open): If called by a setuid/setgid or an
510 otherwise privileged program, be paranoid and ignore the
511 TEST_IO_* environment variables.
513 2005-03-21 Theodore Ts'o <tytso@mit.edu>
515 * Release of E2fsprogs 1.37
517 2005-03-21 Theodore Ts'o <tytso@mit.edu>
519 * ext2_ext_attr.h (EXT2_XATTR_LEN, EXT2_XATTR_SIZE): Add new
520 convenience cpp macros.
522 2005-03-20 Theodore Ts'o <tytso@mit.edu>
524 * mkdir.c (ext2fs_mkdir): Call ext2fs_write_new_inode() instead of
525 ext2fs_write_inode().
527 * inode.c (ext2fs_write_new_inode): New function which should be
528 used when the caller is writing an inode for the first
529 time. It makes sure that the extra portion of the large
530 inode is initialized properly.
532 2005-03-18 Theodore Ts'o <tytso@mit.edu>
534 * Makefile.in: Fix clean target to remove tst_getsectsize.
536 * getsize.c (ext2fs_get_device_size): Check to see if the number
537 of blocks is greater than 2**32 when we are doing a binary
538 search to determine the device size. Thanks to Stephen
539 Tweedie for the patch.
541 2006-02-05 Theodore Ts'o <tytso@mit.edu>
543 * Release of E2fsprogs 1.36
545 2005-02-05 Theodore Ts'o <tytso@mit.edu>
547 * Makefile.in: Remove ext2fs.pc on a "make distclean"
549 2005-02-04 Theodore Ts'o <tytso@mit.edu>
551 * Makefile.in (clean): Remove tst_getsize when doing a make clean
553 2005-02-03 Theodore Ts'o <tytso@mit.edu>
555 * bitops.c: Make the generic functions more efficient.
557 * bitops.h: Drop SPARC assembly code. It's less efficient than GCC
558 3.4 compiled code and also triggers nasty compiler
559 warnings on sparc64. Thanks to Matthias Andree for his
560 analysis and suggestion.
562 2005-01-27 Theodore Ts'o <tytso@mit.edu>
564 * res_gdt.c (ext2fs_create_resize_inode): Create the resize inode
565 even if s_reserved_gdt_blocks is zero.
567 2005-01-26 Theodore Ts'o <tytso@mit.edu>
569 * ext2fs.pc.in: Add pkg-config files.
571 2005-01-25 Theodore Ts'o <tytso@mit.edu>
573 * ext2fs.h: Add definition of struct ext2_inode_large
575 * ext2_fs.h: Add new function prototypes
577 * ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr): The
578 ext2fs_swap_ext_attr() has been moved to swapfs.c, and
579 given a new argument, has_header.
581 * swapfs.c (ext2fs_swap_ext_attr): Moved from ext_attr.c, and
582 takes an argument which controls whether or not there is
583 an EA header which needs to be byteswaped.
584 (ext2fs_swap_inode_full): New function which byte-swaps
587 * inode.c (ext2fs_get_next_inode_full, ext2fs_read_inode_full,
588 ext2fs_write_inode_full): New functions, originally from
589 Alex Tomas, but which needed to be substantially fixed so
590 that the tests wouldn't cause major stack overwrite bugs
591 in byte-swapping is enabled.

595 * Makefile.in: Fix the kernel compile-time echo commands to be
596 consistent and portable
598 2005-01-07 Theodore Ts'o <tytso@mit.edu>
600 * unlink.c (ext2fs_unlink): If both the name and the inode number
601 are unspecified, then return an error, so that we don't do
602 something surprising such as unconditionally deleting the
603 first directory entry.
604 (unlink_proc): Delete directory entries by coalescing it
605 with the previous entry, to avoid directory fragmentation.
607 2005-01-06 Theodore Ts'o <tytso@mit.edu>
609 * version.c (ext2fs_parse_version_string): Change parsing
610 algorithm so that version strings such as 1.36-rc1 returns
611 a non-surprising result (i.e., 136, and not 1361).
613 2005-01-05 Theodore Ts'o <tytso@mit.edu>
615 * block.c (block_iterate_ind, block_iterate_dind,
616 block_iterate_tind): Move the code which byte swaps and
617 read/writes indirect blocks to ext2fs_{read,write}_ind_block.
618 This saves 400 bytes, and we need them for the
619 resize_inode handling.
621 * ind_block.c (ext2fs_read_ind_block, ext2fs_write_ind_block): New
624 * res_gdt.c (ext2fs_create_resize_inode): Use
625 ext2fs_{read,write}_ind_block so that byte swapping is
626 handled on big-endian systems.
628 * dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handle
629 has its own copy of the orig_super data structure. (This
630 is a better way of fixing a double-free problem in
631 resize2fs which Fedora attempted to fix in
632 e2fsprogs-1.35-double_free.patch. Addresses Red Hat
635 2004-12-23 Theodore Ts'o <tytso@mit.edu>
637 * inode.c (ext2fs_flush_icache): When flushing the icache, clear
638 the last-read block information as well.
640 * ext2fs.h (BMAP_SET), bmap.c (ext2fs_bmap): Add support for new
641 flag, BMAP_SET, which allows the caller to set a
642 particular logical->physical block mapping.
644 * ext2_err.et.in (EXT2_ET_SET_BMAP_NO_IND): New error code
646 * initialize.c (calc_reserved_gdt_blocks): #ifdef out all
647 debugging printf statements.
649 * res_gdt.c (ext2fs_create_resize_inode): Return
650 EXT2_ET_RESIZE_INODE_CORRUPT if the resize inode is not
651 what we expect. #ifdef out all debugging printf
654 * ext2_err.et.in (EXT2_ET_RESIZE_INODE_CORRUPT): Add new error code.
656 2004-12-22 Theodore Ts'o <tytso@mit.edu>

664 res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
665 ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
666 ext2fs_bg_has_super() back to closefs.c. There's no
667 reason for the new file, since list_backups() isn't being
668 used by any other functions, and can be made static, and
669 all users of the ext2fs filesystem will have to call
670 ext2fs_close() anyway.
672 2004-12-15 Theodore Ts'o <tytso@mit.edu>
674 * Applied resize inode patch from Andreas Dilger
676 * res_gdt.c (ext2fs_create_resize_inode): New function that
677 creates the resize inode.
679 * initialize.c (ext2fs_initialize): Reserve space for the resize
682 * ext2fs.h (EXT2_LIB_FEATURE_COMPAT_SUPP): Add
683 EXT2_FEATURE_COMPAT_RESIZE_INODE to the list of supported
685 Add function prototypes for res_gdt.c and sparse.c.
687 * closefs.c (ext2fs_super_and_bgd_loc): Take the reserved blocks
688 into account when calculating the number of overhead
691 * closefs.c (ext2fs_bg_has_super, test_root), sparse.c: Move these
692 functions to the new file sparse.c
694 * alloc_sb.c (ext2fs_reserve_super_and_bgd): Reserve the blocks
695 saved in the resize inode as being in use.
697 * ext2_err.et.in (EXT2_ET_RES_GDT_BLOCKS): Add new error code.
699 * Makefile.in (srcdir): Add res_gdt.c and sparse.c to the ext2fs

717 io_channel_write_byte() from a macro to a library function.
719 * ext2fs.h, openfs.c(ext2fs_open2): New version of ext2fs_open
720 which adds a new parameter, io_options.
721 (ext2fs_open): If there is a question mark in the
722 filename, and no io_options are specified, assumed that
723 the text following the question mark are io_options.
725 * io_manager.c, Makefile.in: New source file which contains
726 high-level functions for the io_channel layer.
728 * freefs.c (ext2fs_free): Make sure we don't free the io_channel
731 * Makefile.in: Use Linux-kernel-style makefile output to make it
732 easier to see errors/warnings.
734 2004-11-29 Theodore Ts'o <tytso@mit.edu>
736 * ext2_fs.h (EXT2_EXTENTS_FL, EXT3_FEATURE_INCOMPAT_EXTENTS,
737 EXT2_MAX_BLOCK_LOG_SIZE): Add definition for extent
738 feature and inode flag. Change maximum allowable block
741 2004-10-08 Theodore Ts'o <tytso@mit.edu>
743 * getsize.c (ext2fs_get_device_size): Add support for Windows
744 9x/NT under Cygwin. Thanks to Sam Robb
745 (samrobb@users.sourceforge.net) for pointing this and the
746 suggested code patch.
748 2004-09-17 Theodore Ts'o <tytso@mit.edu>
750 * getsize.c: Clean up header #include's.
752 * llseek.c (ext2fs_llseek): On non-linux systems, use lseek64() if
753 it is present. (Addresses Debian bug #269044)

757 * rw_bitmaps.c (read_bitmaps), block.c (block_iterate_ind,
758 block_iterate_dind, block_iterate_tind), inode.c
759 (ext2fs_read_inode): If EXT2_FLAG_IMAGE_FILE is set, so
760 read the metadata from fs->image_io instead of fs->io.
762 * initialize.c (ext2fs_initialize), openfs.c (ext2fs_open):
763 Initialize fs->image_io to be the same as fs->io.
765 * ext2_err.et.in (EXT2_ET_NOT_IMAGE_FILE): Add new error code.
767 * openfs.c (ext2fs_get_data_io, ext2fs_set_data_io,
768 ext2fs_rewrite_to_io): New functions that allow
769 applications to manipulate fs->image_io and fs->io safely.
771 * freefs.c (ext2fs_free): If fs->image_io is different fs->io,
772 then call io_channel_close on fs->image_io.
774 * ext2fs.h: Add image_io element to the ext2_filsys data
775 structure. Add ext2fs_get_data_io() ext2fs_set_data_io(),
776 and ext2fs_rewrite_to_io() prototypes.

780 * closefs.c (ext2fs_flush): Make sure the master superblock is
781 written last, and only after other I/O has been flushed to
782 disk. Thanks to Junfeng Yang from the Stanford
783 Metacompilation group for pointing a potential ordering
784 constraint problem if we don't write things out in the
787 * test_io.c: Implement the ability to abort after n reads or
788 writes to a particular block. The block is specified by
789 TEST_IO_BLOCK environment variable, and the read/write
790 count by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT
791 environment variables. The block data is now only dumped
792 if the 0x10 bit is set in TEST_IO_FLAGS.
794 2004-04-03 Theodore Ts'o <tytso@mit.edu>
796 * ext2_types.h.in: Remove check for _UUID_TYPES since uuid_types.h
799 2004-03-08 Theodore Ts'o <tytso@mit.edu>
801 * getsize.c (ext2fs_get_device_size): Only use the BLKGETSIZE64
802 ioctl on Linux 2.6 since it is unreliable in Linux 2.4.
803 (Addresses Debian Bug #236528). Fix typo in the ioctl
806 2004-03-02 Theodore Ts'o <tytso@mit.edu>
808 * getsize.c (ext2fs_get_device_size): Update getsize functions to
809 use Apple Darwin and Linux 64-bit ioctl's
811 2004-02-29 Brian Bergstrand <brian@bergstrand.org>
813 * Makefile.in: Use $(BSDLIB_PIC_FLAG) to determine whether to use
816 2004-02-28 Theodore Ts'o <tytso@mit.edu>
818 * Release of E2fsprogs 1.35
820 2004-02-21 Theodore Ts'o <tytso@mit.edu>

827 * namei.c (follow_link): Correctly deal with symlinks that have
828 extended attribute information. (Addresses Debian Bug
831 2004-01-30 Theodore Ts'o <tytso@mit.edu>
833 * ext2_fs.h: Reserve an extra 4 bytes for the journal backup,
834 which we're using due to a typo in the e2fsck code. (Oops)
836 * swapfs.c (ext2fs_swap_inode): Fix byte swap bug which causes SE
837 Linux created symlinks with mandatory attributes to fail
838 to be properly handled on big endian systems. (Addresses
840 (ext2fs_swap_super): Byte swap some new fields in the
841 superblock, including the journal backup fields.
843 2003-12-02 Theodore Ts'o <tytso@mit.edu>

847 get_pathname.c, icount.c, imager.c, initalize.c, inode.c,
848 lookup.c, openfs.c, read_bb.c, read_bb_file.c,
849 rw_bitmaps.c, unix_io.c, unlink.c, write_bb_file.c: Fix
850 gcc -Wall complaints. Mainly marking variables as being
851 unsued, and catching signed vs. unsigned comparisons.
853 2003-09-03 Theodore Ts'o <tytso@mit.edu>
855 * closefs.c (ext2fs_super_and_bgd_loc): New function which
856 centralizes the calculation of the superblock and block
858 (ext2fs_flush): Use ext2fs_super_and_bgd_lock to figure
859 out where to write the superblock and block group
862 * alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
863 reserves space in the block bitmap using
864 ext2fs_super_and_bgd_loc.
866 * initialize.c (ext2fs_initialize): Use
867 ext2fs_reserve_super_and_bgd to initialize the block bitmap.
869 2003-08-20 Theodore Ts'o <tytso@mit.edu>
871 * inode_io.c (ext2fs_inode_io_intern2), ext2fs.h: Add new function
872 allows the caller to pass in the inode data structure.
874 * fileio.c (ext2fs_file_open2), ext2fs.h: Add new function which
875 allows the caller to pass in the inode to be used in the
878 * ext2_fs.h: Add a backup of the location of the journal inode
879 blocks to the superblock.
881 * mkjournal.c (write_journal_inode): Save the location of the
882 journal inode to the backup location in the superblock.
884 2003-08-01 Philipp Thomas <pthomas@suse.de>
886 * alloc.c, badblocks.c, bb_inode.c, bitmaps.c, block.c, bmap.c,

891 mkjournal.c, namei.c, newdir.c, openfs.c, rs_bitmap.c,
892 rw_bitmaps.c, test_io.c, unix_io.c: ext2fs_getmem(),
893 ext2fs_free_mem(), and ext2fs_resize_mem() all now take a
894 'void *' instead of a 'void **' in order to avoid pointer
895 aliasing problems with GCC 3.x.
897 2003-07-25 Theodore Ts'o <tytso@mit.edu>
899 * Release of E2fsprogs 1.34
901 2003-07-06 Theodore Ts'o <tytso@mit.edu>
903 * kernel-jbd.h, flushb.c: Fix gcc -Wall nitpicks (indented cpp
906 * ext2_types.h.in, initialize.c: Fix gcc -Wall nitpicks
909 * ismounted.c: Fix gcc -Wall nitpicks (Don't use exit as a goto label)
911 * llseek.c: Fix gcc -Wall nitpicks (don't use #elsif)
913 * lookup.c, read_bb.c: Fix gcc -Wall nitpicks (indent
914 non-traditional #pragma)
916 * test_io.c: Fix gcc -Wall nitpicks (const/unsigned type issues)
918 2003-06-24 <tytso@snap.thunk.org>
920 * badblocks.c, ext2fs.h (ext2fs_u32_list_find,
921 ext2fs_u32_list_test, ext2fs_u32_list_del,
922 ext2fs_badblocks_list_del): Add functions to delete a
923 block from the badblocks list.
924 * tst_badblocks.c: Add test cases for ext2fs_badblocks_list_del().

934 caching by the unix_io layer. Not enabled, only for
937 2003-05-05 Theodore Ts'o <tytso@mit.edu>
939 * test_io.c: Pay attention to the environment variables
940 TEST_IO_LOGFILE, TEST_IO_FLAGS, and TEST_IO_BLOCK to
941 determine whether or not we should log io activity, and to
944 2003-05-03 Theodore Ts'o <tytso@mit.edu>
946 * tst_badblocks.c (file_test): Use tmpfile() instead of mktemp().
948 2003-04-29 Theodore Ts'o <tytso@mit.edu>
950 * getsize.c (ext2fs_get_device_size): Allow windows code to get
951 the resize for filesystems that are in regular files.
953 2003-04-21 Theodore Ts'o <tytso@mit.edu>
955 * Release of E2fsprogs 1.33
957 2003-04-21 Theodore Ts'o <tytso@mit.edu>
959 * Makefile.in: Use DYLD_LIBRAY_PATH so that "make check" works on
960 Darwin systems when building with shared libraries.
962 2003-04-18 Theodore Ts'o <tytso@mit.edu>
964 * unix_io.c: Use __CYGWIN__ instead of CYGWIN.
966 2003-04-17 Theodore Ts'o <tytso@mit.edu>
968 * getsize.c: Add Cygwin/Windows version of ext2fs_get_device_size()

980 2003-04-11 Theodore Ts'o <tytso@mit.edu>
982 * ext2_fs.h (EXT2_FEATURE_RO_COMPAT_BTREE_DIR): Comment out unused
985 2003-03-30 Theodore Ts'o <tytso@mit.edu>
987 * Makefile.in: Use the compile_et --build-tree option.
989 2003-03-14 Theodore Ts'o <tytso@mit.edu>
991 * getsize.c: Add support for Apple Darwin's ioctl to get the hard

995 which returns the number of entries in the list.
997 2003-03-10 Theodore Ts'o <tytso@mit.edu>
999 * fileio.c (ext2fs_file_lseek): Fix bug added when adding 64-bit
1000 support; avoid null dereference when ret_pos is NULL.
1002 2003-03-06 Theodore Tso <tytso@mit.edu>
1004 * ext2_types.h.in: Don't redefine types if other e2fsprogs
1005 *_types.h files have been included already.
1007 * kernel-jbd.h: Use C99 variadic cpp macros if not using GCC.
1008 (Older GCC's don't support the C99 variadic macros.)
1010 * flushb.c (ext2fs_sync_device),
1011 ismounted.c (ext2fs_check_mount_point): Avoid GCC extension:
1012 #warning not supported by Solaris suncc
1014 * ext2_ext_attr.h: Avoid GCC extension: 0 length arrays in
1015 structure definition. Not needed for now in
1016 ext2_ext_attr_entry.

1026 2003-01-21 Theodore Ts'o <tytso@mit.edu>
1028 * fileio.c (ext2fs_file_read, ext2_file_lseek,
1029 ext2_file_get_size): Add 64-bit support.
1031 * ext2fs.h (EXT2_I_SIZE): Add macro which caluates a 64bit size
1032 from i_size and i_size_high.
1034 2003-01-19 Theodore Ts'o <tytso@mit.edu>
1036 * initialize.c (ext2fs_initialize): If the user specifies a really
1037 large number of inodes, then reduce the number of blocks
1038 per group until we find a workable set of filesystem
1041 * ext2_err.et.in (EXT2_ET_TOO_MANY_INODES): Add new error code.
1043 2002-11-09 Theodore Ts'o <tytso@mit.edu>
1045 * Release of E2fsprogs 1.32
1047 2002-11-09 Theodore Ts'o <tytso@mit.edu>
1049 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
1050 unix_write_blk): Optimize routines so that we don't end up
1051 searching the cache twice when a block isn't in the
1052 cache. If reads are larger than READ_DIRECT_SIZE, don't
1053 let them go through the cache.
1055 * unix_io.c (find_cached_block): Fixed bug which caused some clean
1056 blocks to be erroneously marked as dirty, so they would
1057 get written back to the disk before they are evicted from
1058 the cache. Harmless, but it slows down e2fsck
1061 2002-11-08 Theodore Ts'o <tytso@mit.edu>
1063 * Release of E2fsprogs 1.31
1065 2002-11-08 <tytso@snap.thunk.org>
1067 * Makefile.in (check): Skip trying to compile test_byteswap
1068 if --disable-byteswaap had been given to configure.
1070 2002-11-07 <tytso@snap.thunk.org>
1072 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
1073 support when the MASTER_SB_ONLY flag is set. Some of
1074 the descriptor blocks that should have been written out
1075 were getting skipped.
1077 2002-10-31 Theodore Ts'o <tytso@mit.edu>
1079 * Release of E2fsprogs 1.30
1081 2002-10-31 Theodore Ts'o <tytso@mit.edu>
1083 * ext2_fs.h: Add support for a new inode flag, which is to be used
1084 for indicating the top of directory hierarchies for the
1085 Orlov block allocator.
1087 * ismounted.c (check_mntent, check_mntent_file): Add better
1088 support for loopback-mounted filesystems. Check /etc/mtab
1089 if /proc/mounts doesn't turn up any mount flags, since
1090 /etc/mtab has the loopback image filename, instead of
1091 /dev/loop0. Also, check based on st_dev and st_ino, so
1092 that if a relative pathname or a pathnames using symbolic
1093 links are used, we can detect the the filesystem correctly
1094 in those cases. (Addresses Sourceforge bug #619119)
1096 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
1097 don't try the FDFLUSH ioctl that was required for floppies
1098 with older kernels. This avoids needless whining from the
1099 MD device driver. (Addresses Sourceforge bug #545832).
1101 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
1102 wrong group_block to ext2fs_descriptor_block_loc if we're
1103 using the backup superblock/block group descriptors.
1104 (ext2fs_descriptor_block_loc): If we're using the backup
1105 superblock descriptors, use the backup descriptor block in
1106 the next block group.
1108 2002-10-30 Theodore Ts'o <tytso@mit.edu>
1110 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
1111 table so that it buts up against the bitmap blocks, to
1112 avoid block fragmentation.
1114 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
1115 bug; only allocate group descriptor blocks up to
1118 2002-10-25 Theodore Ts'o <tytso@mit.edu>
1120 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
1121 know when a filesystem was created. (Sometimes this can
1124 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
1126 2002-10-20 Theodore Ts'o <tytso@valinux.com>
1128 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
1129 the journal data mode.
1131 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
1132 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
1133 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
1134 the meta_blockgroup filesystem format.
1136 2002-10-15 <tytso@snap.thunk.org>
1138 * ext2_fs.h: Add new field in superblock for default mount options.
1140 2002-10-13 Theodore Ts'o <tytso@mit.edu>
1142 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
1145 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
1147 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1148 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
1149 because the bitmap is getting written to disk. Make
1150 ext2fs_swap_bitmap be a static function, since it's not
1151 intended to be exported.
1153 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
1155 2001-09-24 Theodore Tso <tytso@mit.edu>
1157 * Release of E2fsprogs 1.29
1159 2001-08-31 Theodore Tso <tytso@thunk.org>
1161 * Release of E2fsprogs 1.28
1163 2002-08-31 Theodore Ts'o <tytso@valinux.com>
1165 * dblist.c (ext2fs_dblist_sort): New function which allows the
1166 caller to pass in a special sort comparison function.
1168 2002-08-20 Theodore Ts'o <tytso@mit.edu>
1170 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
1171 failed to accurately characterize non-standard slow
1172 symlinks. (Which don't appear in practice on real-life
1173 systems, fortunately.)
1175 2002-08-17 Theodore Ts'o <tytso@mit.edu>
1177 * Makefile.in: Remove inode_io.o from the standard object files,
1178 and only build it if debugfs is enabled (it requires
1179 fileio.o, which is only built if --disable-debugfs isn't
1180 specified to configure).
1182 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
1183 incompatible way so that it is no longer
1184 endian-dependent. Add the TEA hash. Allow the seed
1185 parameter to be optional.
1187 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
1188 These features are all now in the HALF_MD4 hash. Add
1189 definition for EXT2_HASH_TEA.
1191 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
1192 a pointer instead of an array.
1194 2002-08-16 Theodore Ts'o <tytso@mit.edu>
1196 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
1198 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
1199 the number of data blocks used by an inode exclusive of
1202 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
1203 adjusts the reference count in an extended attribute block.
1205 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
1206 correctly deal with extended attribute blocks in symbolic
1209 2002-08-13 <tytso@snap.thunk.org>
1211 * Makefile.in: Move dupfs.o and test_io.o from the
1212 needed-by-debugfs object list to the needed-by-resizer
1213 object list. Fixes compile problem if the system is built
1214 with only --disable-debugfs.
1216 2002-07-29 Theodore Ts'o <tytso@mit.edu>
1218 * link.c (ext2fs_link): When adding a new link to a directory,
1219 clear the HTREE bit.
1221 2002-07-23 Theodore Ts'o <tytso@mit.edu>
1223 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
1224 calculations for names > 32 characters to be completely
1225 bogus. Changed MD4 calculation to match what is currently
1226 being used in the CVS gkernel tree.
1228 2002-07-19 Theodore Ts'o <tytso@mit.edu>
1230 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
1231 superblock definition.
1233 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
1234 create a set of u32_list functions.
1236 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
1237 since that's required by the directory indexing code.
1239 2002-07-14 Theodore Ts'o <tytso@mit.edu>
1241 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
1242 using a C++ reserved word.
1244 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
1245 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
1246 old version of glibc (built against 2.2 headers) will
1247 interact badly with the workaround to actually cause more
1248 problems. I hate it when the glibc folks think they're
1249 being smarter than the kernel....
1251 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
1253 * ext2_fs.h: Add superblock field for reserved group descriptors.
1255 2002-06-28 Theodore Ts'o <tytso@mit.edu>
1257 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
1258 ext2fs_cpu_to_{l,b}e{32,16}
1260 2002-06-27 Theodore Ts'o <tytso@mit.edu>
1262 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
1263 Add appropriate fallbacks in this case.
1265 2002-06-26 Theodore Ts'o <tytso@mit.edu>
1267 * dirhash.c (ext2fs_dirhash): Change function signature to support
1268 a hash seed, and to return the minor hash (for 64-bit hash
1269 support). Add support for the half MD4, half MD4 with
1270 seed, and half MD4 with seed and 64 bits.
1272 2002-06-15 Theodore Ts'o <tytso@mit.edu>
1274 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
1276 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
1278 * ext2_fs.h: Add macros for maximum block/inode counts:
1279 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
1280 and EXT2_MAX_INODES_PER_GROUP.
1282 * openfs.c (ext2fs_open): Check that the number of blocks in a group
1283 is less than 2^16, otherwise we need an INCOMPAT flag (not
1284 in existence yet, if ever) to open such a filesystem.
1286 * initialize.c (ext2fs_initialize): Limit the number of blocks and
1287 inodes in a group to less than 2^16.
1289 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
1291 * ext2_fs.h: Further minor cleanups of the header. Consolidate
1292 some checks for __KERNEL__ into one place.
1294 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
1296 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
1297 the EXT2_SB() macro instead. Remove kernel function
1298 prototypes also. This matches the 2.5 kernel, and
1299 is also cleaner for other reasons. Whitespace cleanup.
1301 2002-05-21 Theodore Ts'o <tytso@mit.edu>
1303 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
1305 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
1307 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
1309 * initialize.c (ext2fs_initialize): Remove assumption that
1310 blocksizes are always <= 4k.
1312 2002-05-11 Theodore Ts'o <tytso@mit.edu>
1314 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
1315 silently if inode pointer is NULL (and ext2fs_bmap is
1316 expected to read the inode itself).
1318 2002-04-27 Theodore Ts'o <tytso@mit.edu>
1320 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
1321 file we are checking is a block device file before looking
1322 at st_rdev, since it's not valid for normal files.
1323 (is_swap_device): Move so that it is outside the
1324 HAVE_MNTENT_H, so that it is always built.
1326 2002-03-11 Theodore Tso <tytso@mit.edu>
1328 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
1329 functions which take an extra flags argument. The flag
1330 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
1331 field is byte swampped on big-endian machines, since in
1332 the V2 structure, name_len is a char field which is
1333 doesn't need to be byte swapped --- except if an
1334 old-style kernel had byte-swapped the name_len field
1335 as part of the V1 structure.
1337 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
1339 * dirhash.c (ext2fs_dirhash): New function which calculates the
1340 hash for a filename in an indexed directory.
1342 2002-03-08 Theodore Tso <tytso@mit.edu>
1344 * Release of E2fsprogs 1.27
1346 2002-03-07 Theodore Tso <tytso@mit.edu>
1348 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
1350 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
1351 tst_byteswap.c: Fix gcc -Wall complaints
1353 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
1354 (From Philipp Thomas <pthomas@suse.de>)
1356 2002-02-25 Theodore Tso <tytso@mit.edu>
1358 * ext2_fs.h: Add structure definitions for the directory indexing
1361 2002-02-23 Theodore Tso <tytso@mit.edu>
1363 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
1364 it doesn't break things on mis32, sparc32, and alpha
1367 2002-02-21 Theodore Tso <tytso@mit.edu>
1369 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
1370 we were missing an fclose().
1372 2002-02-20 Theodore Tso <tytso@mit.edu>
1374 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
1375 abstraction interface which exports an ext2 inode.
1377 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
1378 as a public interface. Change void * to const void * in
1379 ext2fs_file_write's interface.
1381 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
1382 conditional; save a few bytes.
1384 2002-02-12 Theodore Tso <tytso@mit.edu>
1386 * Makefile.in (tst_badblocks): Add some extra .o files when
1387 linking the debugging program tst_badblocks which are
1388 needed if we aren't compiling with inline functions enable.
1390 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
1391 define away __inline__ since it may not be supported.
1393 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
1394 stripped down jbd_debug that doesn't use variadic
1395 arguments. This will cause warnings under AIX, but things
1398 2002-02-03 Theodore Tso <tytso@thunk.org>
1400 * Release of E2fsprogs 1.26
1402 2002-02-03 Theodore Tso <tytso@mit.edu>
1404 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
1405 so that the number of directories in use is adjusted
1408 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
1409 which optionally will modify the number of directories
1412 2002-01-03 Theodore Tso <tytso@mit.edu>
1414 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
1415 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
1416 which will return deleted directory entries.
1417 ext2fs_dir_iterate2 takes a new callback function which
1418 is identical with the one used by
1419 ext2fs_dblist_dir_iterate(). If the directory entry is
1420 deleted, the callback function will be called with the
1421 entry paraemter set to DIRENT_DELETED_FILE.
1423 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
1424 ext2fs_block_alloc_stats): New functions which update
1425 block/inode allocation statistics in the bitmaps, block
1426 group descriptors, and superblock.
1428 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
1429 expanddir.c (expand_dir_proc), bb_inode.c
1430 (clear_bad_block_proc, set_bad_block_proc,
1431 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
1432 Update to use new block/inode allocation statistics.
1434 2001-12-24 Theodore Tso <tytso@mit.edu>
1436 * ismounted.c (is_swap_device): New function used by
1437 ext2fs_check_if_mounted and ext2fs_check_mount_point which
1438 determines whether or not the specified device is a swap
1439 device by using /proc/swaps. More bulletproofing for
1440 idiotic/careless system administrators!
1442 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
1443 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
1444 field to struct_ext2_filsys, umask. This field is
1445 initialize to 022, and affects ext2fs_mkdir in the obvious
1446 way. (In the future umask should also affect new file
1447 creation routines, but the fileio functions don't
1448 currently support this yes.)
1450 * ismounted.c (check_mntent_file): Stat all of the entries in
1451 /etc/mtab and/or /proc/mounts in order to catch dim-witted
1452 system administrators who might have created alias
1455 2001-12-23 Theodore Tso <tytso@mit.edu>
1457 * Makefile.in, jfs_user.h: Move linux/jbd.h to
1458 ext2fs/kernel-jbd.h, to avoid using the system header
1459 file version of hbd.h when using diet glibc (since it
1460 forcibly adds /usr/include to the beginning of the
1461 include search path.)
1463 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
1464 include/linux directory.
1466 2001-12-16 Theodore Tso <tytso@mit.edu>
1468 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
1469 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
1470 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
1472 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
1475 2001-12-03 Theodore Tso <tytso@mit.edu>
1477 * unix_io.c (unix_open): Make sure the ulimit workaround works
1478 regardless of the version of glibc which is used to
1481 2001-11-26 Theodore Tso <tytso@mit.edu>
1483 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
1484 trying to unset the filesize limit if at all possible,
1485 if a block device is getting opened. (The filesize limit
1486 shouldn't be applied against writes to a block device, but
1487 starting in 2.4.10, the kernel is doing this.)
1489 2001-11-05 Theodore Tso <tytso@mit.edu>
1491 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
1492 file on adding a journal to an already-mounted filesystem,
1493 try to clear the ext2 file attributes on an already
1494 existing .journal file so that we don't fail if on a
1495 partially added journal to the filesystem.
1497 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
1498 which signals that a particular inode should not have the
1499 last bits of data (the "tail") be merged with another
1500 file. This is necessary to keep LILO happy.
1502 2001-09-20 Theodore Tso <tytso@thunk.org>
1504 * Release of E2fsprogs 1.25
1506 2001-09-16 Theodore Tso <tytso@mit.edu>
1508 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
1509 which was breaking the build on the Hurd. (Addresses
1510 Debian bug #112414).
1512 2001-09-13 Theodore Ts'o <tytso@mit.edu>
1514 * ismounted.c (check_mntent_file): We now validate the entry in
1515 /etc/mtab to make sure the filesystem is really mounted,
1516 since some broken distributions (read: Slackware) have
1517 buggy boot scripts that don't initialize /etc/mtab before
1518 checking non-root filesystems. (Slackware also doesn't
1519 check the root filesystem separately, and reboot if the
1520 root filesystem had changes applied to it, which is
1521 dangerous and broken.)
1523 2001-09-02 Theodore Tso <tytso@thunk.org>
1525 * Release of E2fsprogs 1.24a
1527 2001-08-30 Theodore Tso <tytso@thunk.org>
1529 * Release of E2fsprogs 1.24
1531 2001-08-30 Theodore Tso <tytso@valinux.com>
1533 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
1534 changes, since the ioctl number has been reused by another
1537 2001-08-15 Theodore Tso <tytso@valinux.com>
1539 * Release of E2fsprogs 1.23
1541 2001-08-05 Theodore Tso <tytso@valinux.com>
1543 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
1544 version of the bitmap test routines to speed up these
1545 routines. (At some point I may want to make these
1546 routines use the find_first_bit functions, but that will
1547 add a lot of complexity since it means that these
1548 functions will have to break the bitmap abstraction
1549 boundary. It's not clear it's worth it.)
1551 * mkjournal.c (mkjournal_proc): Remember the last block allocated
1552 to speed up ext2fs_new_block().
1554 2001-07-29 Theodore Tso <tytso@valinux.com>
1556 * finddev.c (scan_dir): Fix memory leak; we weren't calling
1557 closedir() when exiting the function in all cases.
1559 2001-07-27 Theodore Tso <tytso@valinux.com>
1561 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
1562 block usable in the journal for external journals to be 2
1563 or 3, depending on the blocksize, so that the existing
1564 kernel code does the right thing.
1566 * getsize.c (ext2fs_get_device_size): Add support for the
1567 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
1568 from Ben LaHaise, but it's likely this interface won't
1571 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1572 when writing the journal superblock, too. (Oops! Needed
1573 to make 1k filesystems with external journal to work.)
1575 2001-07-26 Theodore Tso <tytso@valinux.com>
1577 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1578 to find the journal superblock if the blocksize is 1024.
1580 2001-07-21 Theodore Tso <tytso@valinux.com>
1582 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
1584 2001-07-20 Theodore Tso <tytso@valinux.com>
1586 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
1587 attribute block, set the filesystem changed bit.
1589 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1590 Comment out these functions since we're not using them.
1592 2001-07-10 Theodore Tso <tytso@valinux.com>
1594 * closefs.c (write_primary_superblock): After writing changes to
1595 the primary superblock, update the original superblock
1596 copy so we don't have to re-write those changes in the
1598 (ext2fs_flush): Clear the superblock dirty flag after
1599 we've flushed out changes to disk.
1601 2001-07-07 Theodore Tso <tytso@valinux.com>
1603 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
1604 to avoid register conflicts when compiling in PIC mode.
1606 2001-07-04 Theodore Tso <tytso@valinux.com>
1608 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1609 Add new functions (C and in i386 assembler) which quickly
1610 find bits set in a bitmask.
1612 2001-06-23 Theodore Tso <tytso@valinux.com>
1614 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
1615 ext2_ext_attr.h and ext_attr.c for extended attributes
1618 * Release of E2fsprogs 1.22
1620 2001-06-22 Theodore Tso <tytso@valinux.com>
1622 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
1623 descriptor so that adding a journal to a mounted
1624 filesystem doesn't die. (Fixes a bug accidentally
1625 introduced in e2fsprogs 1.21.)
1627 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
1628 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
1629 fchflags without defining UF_NODUMP. (Addresses Debian
1632 * flushb.c: Use platform independent method of defining the
1633 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
1634 since on newer glibc's BLKFLSBUF is defined there.
1636 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
1637 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
1638 to support byte swapping even if we don't support the
1639 conversion functions. (Fixes Debian bug #101686).
1641 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
1642 since the byte-swapping code all assumes the
1643 ext2_dir_entry structure. (It's a question of whether or
1644 not name_len should be byte-swapped or not, and whether
1645 it's a 16 bit or 8 bit field.)
1647 2001-06-15 Theodore Tso <tytso@valinux.com>
1649 * Release of E2fsprogs 1.21
1651 2001-06-15 Theodore Tso <tytso@valinux.com>
1653 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
1654 file which is generated and is therefore found in the
1655 build directory, not source directory.
1657 * ismounted.c (check_mntent_file): Use a test file in / to check
1658 to see if the root filesystem is mounted read-only. This
1659 protects against the case where /etc might not be on /, as
1660 well as the case where /etc/mtab doesn't exist. (Both are
1661 should-never happen scenarios, but you never know...)
1663 2001-06-14 Theodore Tso <tytso@valinux.com>
1665 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
1666 Remove unneeded #pragma argsused, since the arguments are
1669 2001-06-13 Theodore Tso <tytso@valinux.com>
1671 * ext2_types.h.in: If linux/types.h has been defined, then don't
1672 try to redefine the typedefs.
1674 * Makefile.in (HFILES): Add ext2_types.h to the list of files
1675 which should be installed.
1677 * ismounted.c (check_mntent_file): Work around GNU hurd brain
1678 damage. Addresses Debian bug #100304.
1680 * Makefile.in: Limit some .o files from being included into the
1681 library if --disable-debugfs, --disable-swapfs,
1682 --disable-imager, or --disable-resizer are used.
1684 2001-06-12 Theodore Tso <tytso@valinux.com>
1686 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
1687 function, and use the ext2fs_badblocks_* functions
1690 2001-06-11 Theodore Tso <tytso@valinux.com>
1692 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
1693 ext2fs_mark_generic_bitmap and
1694 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
1695 functions. (This saves space and doesn't significantly
1696 change the speed of e2fsck on a P-III.)
1698 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
1699 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
1700 include the byte-swapping logic if ENABLE_SWAPFS is turned
1701 on or if we're on a big-endian machine.
1703 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
1704 set EXT2_FLAG_SWAP_BYTES, instead of using
1707 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
1708 autoconf to determine whether or not return
1709 EXT2_FLAG_SWAP_BYTES.
1711 2001-06-10 Theodore Tso <tytso@valinux.com>
1713 * Makefile.in: Remove the dependence on the libe2p library.
1715 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
1716 with direct usage of the ioctl/fchflags so that we don't
1717 have to depend on the libe2p library.
1719 2001-06-08 Theodore Tso <tytso@valinux.com>
1721 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
1722 when trying to find a 32-bit wide type.
1724 * icount.c (insert_icount_el): Fix the code used to estimate the
1725 size of the new icount array to be more intelligent, to
1726 avoid reallocating the array too many times. Thanks to
1727 Enrique Perez-Terron for pointing this out.
1729 2001-06-02 Theodore Tso <tytso@valinux.com>
1731 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
1732 for a symlink to determine whether it is a fast symlink.
1734 2001-06-01 Theodore Tso <tytso@valinux.com>
1736 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
1737 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
1739 2001-05-25 Theodore Tso <tytso@valinux.com>
1741 * Release of E2fsprogs 1.20
1743 2001-05-25 Theodore Tso <tytso@valinux.com>
1745 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
1746 some to clean up Andreas's patches. Use strncpy instead
1747 of strcpy to save the root's mountpoint. Clean up #ifdef
1748 structure. Remove uneeded variable in testing/debug driver.
1750 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
1752 * ismounted.c: Add check for root device which doesn't depend on
1753 /etc/fstab or /proc/mounts to be correct. Don't call
1754 endmntent() before we are done with mnt struct.
1756 2001-05-23 Theodore Tso <tytso@valinux.com>
1758 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
1761 2001-05-21 Theodore Tso <tytso@valinux.com>
1763 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
1764 make room for pre-existing usage of
1765 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
1766 the same codepoint as EXT2_BTREE_FL.
1768 2001-05-20 Theodore Tso <tytso@valinux.com>
1770 * ext2fs.h: #include <> instead of "" for ext2fs and et header
1771 files, since they will be installed in /usr/include
1773 2001-05-14 Theodore Tso <tytso@valinux.com>
1775 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
1776 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1777 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
1778 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,
1779 expanddir.c, ext2_fs.h, fileio.c, finddev.c, flushb.c,
1780 freefs.c, get_pathname.c, getsize.c, icount.c, imager.c,

1786 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
1787 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
1788 Adjust all files in this directroy to include this file.
1790 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
1793 2001-05-05 Theodore Tso <tytso@valinux.com>
1795 * fileio.c (ext2fs_file_read): Factored out common code and
1796 cleaned up function. Fixed a bug where if there was an
1797 error reading from the disk, the number of bytes read
1798 wasn't reliably set. (Fixes Debian bug #79163)
1799 (ext2fs_file_write): Factored out common code and made
1800 function more efficient; if writing a full block, don't
1801 bother to do a read-modify-write cycle.
1803 2001-05-04 Theodore Tso <tytso@valinux.com>
1805 * dirblock.c (ext2fs_read_dir_block): Check for an directory
1806 record length which isn't a multiple four, and treat that
1807 as an invalid. Scan the directory and return an error
1808 (EXT2_ET_DIR_CORRUPTED) if the directory records are
1810 (ext2fs_write_dir_block): If while byte-swapping the
1811 directory block, if there's an error, abort and return
1812 EXT2_ET_DIR_CORRUPTED.
1814 2001-05-02 Theodore Tso <tytso@valinux.com>
1816 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
1817 image_header field in the ext2_filsys structure
1819 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
1820 * inode.c (ext2fs_read_inode):
1821 * rw_bitmaps.c (read_bitmaps):
1822 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
1824 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
1825 sure the full bitmap is saved.
1827 2001-05-01 Theodore Tso <tytso@valinux.com>
1829 * e2image.h (struct ext2_image_hdr): Add space for the device name
1830 in the image header.
1832 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
1833 make sure the rec_len is a multiple of 4, to prevent
1834 bus-errors on architectures which care about mis-aligned
1837 2001-04-25 Theodore Tso <tytso@valinux.com>
1839 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
1840 query the device sizes using the BLKGETSIZE ioctl.
1842 2001-04-16 Theodore Tso <tytso@valinux.com>
1844 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
1845 before checking /etc/mtab. The EXT2_MF_READONLY flag is
1846 now set from the /etc/mtab options field for all
1847 filesystems, not just the root filesystem. Add debugging
1848 code to make it easier to test ext2fs_check_if_mounted().
1850 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
1851 check; return an error if there's an attempt to create a
1852 journal less than 1024 filesystem blocks.
1854 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
1855 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
1857 2001-02-20 Theodore Tso <tytso@valinux.com>
1859 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
1862 * tst_byteswap.c: New function to test the byteswap functions.
1863 Add to regression test suite.
1865 2001-02-08 Theodore Tso <tytso@valinux.com>
1867 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
1869 2001-02-07 Theodore Tso <tytso@valinux.com>
1871 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
1872 of s_first for external devices to always be 1, since
1873 jsb->s_first is always relative to the start of the
1874 journal superblock. Use htonl(1) when setting s_nr_users.
1876 2001-01-17 Theodore Ts'o <tytso@valinux.com>
1878 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
1879 device number of the filesystem (instead of the journal)
1880 was being dropped into s_journal_dev.
1882 2001-01-15 Theodore Ts'o <tytso@valinux.com>
1884 * initialize.c (ext2fs_initialize): Add support for initializing
1885 the ext2 superblock for external journal devices. This
1886 basically means we don't bother to allocate any block
1889 * openfs.c (ext2fs_open): Only open external journal devices if
1890 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
1891 ext2fs_open. When opening such devices, don't try to read
1892 the block group descriptors, since they're not there.
1894 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
1896 * mkjournal.c: Export a new function,
1897 ext2fs_create_journal_superblock(), which allocates and
1898 returns a buffer containing a journal superblock. This is
1899 needed by mke2fs to create an external journal. Rewrote
1900 ext2fs_add_journal_device() so that it no longer creates
1901 the external journal, but rather adds a filesystem to an
1902 existing external journal. It handles all of the UUID
1905 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
1906 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
1907 Changed function prototype for ext2fs_add_journal_device().
1909 2001-01-14 Theodore Ts'o <tytso@valinux.com>
1911 * closefs.c (ext2fs_flush): Don't write out anything beyond the
1912 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
1915 2001-01-12 Theodore Ts'o <tytso@valinux.com>
1917 * imager.c: Fix gcc -Wall complaints and a series of bugs where
1918 retval wasn't set correctly. (Thanks to Andreas Dilger
1919 for pointing this out.)
1921 2001-01-11 <tytso@snap.thunk.org>
1923 * flushb.c (ext2fs_sync_device): New function which centralizes
1924 all of the places which might try to use the BLKFLSBUF
1925 or FDFLUSH ioctls (and usually failing to define them
1926 since the system header files don't usually do this for
1927 us, and we're trying to avoid usage of kernel include
1930 2001-01-10 <tytso@snap.thunk.org>
1932 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
1933 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
1934 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
1935 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
1936 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
1937 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
1938 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
1939 ext2_ino_t, to protect applications that attempt to
1940 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
1941 changes ino_t(!?). So we use ext2_ino_t to avoid an
1942 unexpected ABI change.
1944 2001-01-05 <tytso@snap.thunk.org>
1946 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
1947 we may overrun allocated memory in case of a corrupted
1948 filesystem (or an e2fsck test case :-) when byte-swapping
1949 the directory block.
1951 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
1953 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
1954 complaints including a missing return 0 at the end of
1955 ext2fs_add_journal_device.
1957 2001-01-03 <tytso@snap.thunk.org>
1959 * Makefile.in: Link in libe2p when creating libext2fs as a shared
1960 library, since mkjournal.c now references fsetflags().
1962 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
1963 Dilger's changes (with fixups) to allow on-line creation
1966 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
1967 EXT2_FLAG_SUPER_ONLY, which the close routines to only
1968 update the superblock, and not the group descriptors.
1970 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
1972 * ismounted.c: add ext2fs_check_mount_point() function, which will
1973 optionally return the mount point of a device if mounted
1975 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
1977 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
1978 ext2fs_add_journal_inode()
1980 2001-01-01 <tytso@snap.thunk.org>
1982 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
1983 source (but not binary) compatibility of some users of the
1984 ext2 library. They should just simply do a global search
1985 and replace of struct ext2fs_sb with struct
1986 ext2_super_block, and use their own private copy of
1987 ext2_fs.h if they aren't already.
1989 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
1990 Replace use of ext2fs_sb with ext2_super_block.
1992 2000-12-31 <tytso@snap.thunk.org>
1994 * ext2fs.h: Cleaned up header file by removing definitions of
1995 feature flags that might not have been defined in older
1996 ext2 header files. Now that we're using our own
1997 include/linux/ext2fs.h header file, this can never happen.
1999 * jfs_dat.h: Removed old header file which is no longer needed.
2001 2000-12-13 Theodore Ts'o <tytso@valinux.com>
2003 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
2004 by Andreas Dilger to update the filesystem revision to
2007 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
2010 2000-12-09 <tytso@snap.thunk.org>
2012 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
2013 ext2fs_add_journal_device): Add a new argument to the APIs
2014 of these function, which is a flags word. This is used to
2015 allow the creation of a V1 superblock for those folks who
2016 are using ext3 0.3b in production. Note, the user-land
2017 interface for getting at this flag won't be documented, as
2018 the V1 superblock is deprecated.
2020 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
2021 which creates a V2 superblock instead of a V1 superblock.
2023 2000-11-21 <tytso@snap.thunk.org>
2025 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
2026 out by Andreas Dilger.
2028 2000-11-05 <tytso@snap.thunk.org>
2030 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
2031 ext2_fs.h, Makefile.in: New file that has routines that
2032 save ext2fs metadata to a file.
2034 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
2036 * e2image.h: New file which defines the file format for the ext2
2037 image file. (Saved copy of ext2 metadata to a file as a
2038 saving throw against worst-case damage.)
2040 2000-11-01 <tytso@snap.thunk.org>
2042 * inode.c (ext2fs_flush_icache): Add new function
2043 ext2fs_flush_icache() which flushes the internal inode
2044 cache. Applications which modify the inode table blocks
2045 directly must call this function.
2047 2000-10-26 <tytso@snap.thunk.org>
2049 * mkjournal.c: Add #include of netinet/in.h, since Solaris
2050 requires it for ntohl().
2052 * ext2_io.h (io_channel_write_byte): Add new interface to allow
2053 callers to write specific byte ranges. This is an
2054 optional interface, which not all IO channels may
2057 * unix_io.c (unix_write_byte):
2058 * test_io.c (test_write_byte): Add implementation of the
2059 write_byte function.
2061 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
2062 function which writes the primary superblock. If the IO
2063 channel supports writing raw bytes directly, only fields
2064 which were modified are written to the disk. This makes
2065 it safe(r) to use utilities like tune2fs on a mounted
2068 * freefs.c (ext2fs_free): Free the original superblock if it is
2071 * openfs.c (ext2fs_open): Store a copy of the original superblock
2074 * ext2fs.h: Add a field to store the original superblock in the
2075 ext2 context structure.
2077 2000-10-24 <tytso@snap.thunk.org>
2079 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
2080 don't need to use llseek).
2082 2000-10-24 <tytso@valinux.com>
2084 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
2085 creating an ext3 journal on a filesystem.
2087 2000-08-21 <tytso@valinux.com>
2089 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
2091 2000-08-22 <tytso@valinux.com>
2093 * unix_io.c: Make massive changes to support a multiple block
2094 writethrough cacheing.
2096 * ext2_io.h: Added flags field to the io_channel structure.
2098 2000-08-19 <tytso@valinux.com>
2100 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
2101 provides the function ext2fs_find_block_device(). This
2102 function returns the pathname to a block device, given its
2105 2000-07-13 <tytso@valinux.com>
2107 * Release of E2fsprogs 1.19
2109 2000-07-07 Theodore Ts'o <tytso@valinux.com>
2111 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
2112 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
2113 list of filesystem flags supported by the library.
2115 2000-07-04 Theodore Ts'o <tytso@valinux.com>
2117 * ext2fs.h: Update to include latest journalling additions to the
2120 * dll/jump.funcs: Add new jumptable entries for
2121 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
2122 ext2fs_badblocks_equal.
2124 * tst_badblocks.c: Update test program to test
2125 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
2127 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
2128 writes out bad blocks list to a file.
2130 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
2131 changes the callback function to take two additional
2132 arguments; a private blind pointer supplied by the caller,
2133 and pointer to a char * containing a pointer to the
2136 * badblocks.c (ext2fs_badblocks_equal): Add new function which
2137 returns true if two badblocks list are equal.
2139 * Makefile.in: Remove explicit link of -lc in the shared library.
2140 (It shouldn't be necessary, and is harmful in some cases).
2142 2000-06-10 Theodore Ts'o <tytso@valinux.com>
2144 * getsize.c (main): Add debugging code under #ifdef DEBUG
2146 2000-05-27 Theodore Ts'o <tytso@valinux.com>
2148 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
2149 earlier, so that if there's an error reading it, we can
2150 more cleanly back out of the operation.
2152 2000-05-25 <tytso@snap.thunk.org>
2154 * getsize.c (ext2fs_get_device_size): Use open64() instead of
2155 open() if it exists. Under linux, manually define the
2156 ioctl for BLKGETSIZE if it isn't already defined and it's
2159 * unix_io.c (unix_open): Use open64() instead of open() if it
2162 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
2163 available (and prototypes are defined) use it in
2164 preference to llseek.
2166 * Makefile: Add hack dependency rule so that parallel makes work
2169 2000-05-18 Theodore Ts'o <tytso@valinux.com>
2171 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
2173 2000-04-03 Theodore Ts'o <tytso@valinux.com>
2175 * block.c: Readibility tweak in conditionals involving
2178 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
2179 how to define __s64 and __u64. Turn off "compression is
2180 experimental" warning if the cpp macro
2181 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
2183 2000-02-11 <tytso@snap.thunk.org>
2185 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
2186 Conditionally include Compression as a supported type if
2187 ENABLE_COMPRESSION (via --enable-compression) is turned on.
2189 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
2191 2000-02-08 <tytso@snap.thunk.org>
2193 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
2194 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2195 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
2196 Change to return the previous state of the bit that is
2197 being marked or unmarked. For speed optimization.
2199 2000-02-02 Theodore Ts'o <tytso@valinux.com>
2201 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
2203 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
2204 needed any more; we know it will always be i_generation.
2205 Add support for swapping the high bits of the uid and gid.
2207 1999-11-19 <tytso@valinux.com>
2209 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
2210 counts if the link was successful. Patch suggested by
2213 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
2214 the source directory.
2216 1999-11-10 <tytso@valinux.com>
2218 * Release of E2fsprogs 1.18
2220 1999-11-08 <tytso@valinux.com>
2222 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
2223 since ext2fs_badblocks_list_free was moved to freefs.c.
2225 * tst_badblocks.c: Use the newer badblocks API names. Add
2226 duplicate blocks to the test inputs to test dealing with
2227 adding blocks which are already in the badblocks list.
2229 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
2230 of the list, use a shortcut O(1) operations instead of an
2231 O(n) operation. (Idea suggested by David Beattie.)
2233 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
2234 of badblocks_list_free(), to save a procedure call.
2236 1999-10-26 <tytso@valinux.com>
2238 * Release of E2fsprogs 1.17
2240 1999-10-26 <tytso@valinux.com>
2242 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
2243 seem to handle ~0UL the same way as they used to.
2245 1999-10-25 <tytso@valinux.com>
2247 * nt_io.c (_OpenNtName): Open the device using
2248 FILE_SYNCHRONOUS_IO_NONALERT instead of
2249 FILE_SYNCHRONOUS_IO_ALERT
2250 (nt_open): At the end of the device open routine, unlock
2251 the drive but do not dismount it.
2253 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
2256 1999-10-22 <tytso@valinux.com>

2260 1999-10-22 <tytso@valinux.com>
2262 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
2264 * link.c (ext2fs_link): This call now uses the low three bits of
2265 the flags parameter to pass the directory filetype
2266 information; it will set the directory entry FILETYPE
2267 information if the filesystem supports it.
2269 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
2270 option is set, then create the '.' and '..' entries with
2271 the filetype set to EXT2_FT_DIR.
2273 1999-09-24 <tytso@valinux.com>
2275 * nt_io.c: New file which supports I/O under Windows NT.
2277 1999-09-07 <tytso@valinux.com>
2279 * ext2fs.h: Add new fields for journalling and define new
2280 feature bits used by newer filesystems: IMAGIC_INODES,
2281 HAS_JOURNAL, RECOVER.
2283 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
2284 we update the inode block count and size files so that the
2285 block count field is updated correctly when we create an
2288 1999-07-18 Theodore Ts'o <tytso@valinux.com>
2290 * Release of E2fsprogs 1.15
2292 1999-06-23 <tytso@valinux.com>
2294 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
2295 kernels that use i_generation instead of i_version. Patch
2296 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
2298 1999-06-21 <tytso@valinux.com>
2300 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
2301 directory entry before calling the callback function.
2302 This should prevent some core dumps of insufficiently
2303 paranoid callback functions.
2305 1999-05-29 <tytso@rsts-11.mit.edu>
2307 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
2309 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
2310 that we don't handle writing yet (we do). Fixed bug where
2311 we weren't allocating a big enough buffer for ext2_bmap.
2313 1999-05-03 <tytso@rsts-11.mit.edu>
2315 * openfs.c (ext2fs_open): Check to make sure that the number of
2316 blocks per group is not zero --- if so, it must be a bad
2319 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2321 * Release of E2fsprogs 1.14
2323 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
2325 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
2326 the inode number is zero; if it's zero, return
2327 EXT2_ET_BAD_INODE_NUM.
2329 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2331 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
2332 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
2335 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
2337 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
2338 non-Linux case to use EINVAL by default, unless it isn't
2339 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
2342 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
2344 * Release of E2fsprogs 1.13
2346 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
2348 * Makefile.in: Updated dependencies.
2350 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
2352 * initialize.c (ext2fs_initialize): Make sure that we allocate
2353 enough inodes so that we can make a valid filesystem.
2355 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
2357 * rw_bitmaps.c: Fixed signed/unsigned warnings.
2359 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
2360 function declaration.
2362 * dblist.c (make_dblist): Add safety check in case the dblist
2363 pointer passed in is null (in which case, assign it to
2364 fs->dblist). Fixed some signed/unsigned warnings.
2366 * bmap.c: Make addr_per_block be of type blk_t to avoid
2367 signed/unsigned warnings.
2369 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
2370 function declaration.
2372 * get_pathname.c (get_pathname_proc): Use return value from
2373 ext2fs_get_mem, instead of checking if &gp->name is
2376 * dir_iterate.c (ext2fs_process_dir_block):
2377 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
2378 from the function declaration.
2380 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
2381 return the error directly instead of jumping to the
2382 cleanup routine, since we don't need to do any cleanup.
2384 * alloc_table.c (ext2fs_allocate_group_table): Make this
2385 function take a dgrp_t for its group argument.
2387 * ext2fs.h: Make dgrp_t an __u32 type, and make
2388 fs->desc_group_count be of type dgrp_t.
2390 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
2392 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
2393 than 10 blocks when we need to expand the size of the
2396 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2398 * Release of E2fsprogs 1.12
2400 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2402 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
2403 appropriate for all of the block group copies, so that
2404 it's clear where the beginning of the filesystem is on the
2405 disk. (For when the partition table gets scrod.)
2407 * ext2fs.h: Change the name of the feature from
2408 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
2409 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
2411 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
2413 * inode.c (get_next_blockgroup): Fix bug where if
2414 get_next_blockgroup() is called early because of a missing
2415 inode table in a block group, the current_inode counter
2416 wasn't incremented correctly.
2418 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
2420 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
2421 against a completely trashed bad block inode.
2423 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
2425 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
2426 the stride length hits a bad value, we retry the block
2427 allocation starting at the beginning of the block group.
2429 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
2430 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
2431 e2_blkcnt_t to avoid collision with LFS API.
2433 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
2435 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
2436 way that avoids overflows on disk sizes greater than 4GB.
2438 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
2440 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
2441 return type for comparison functions for qsort.
2443 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
2446 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
2448 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
2451 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
2452 evade a potential problem with glibc's header files trying
2453 to spike out linux/types.h.
2455 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
2456 include the old size of the memory, which is needed for
2457 some braindamaged memory allocation systems that don't
2460 * badblocks.c (ext2fs_badblocks_list_add):
2461 bb_inode.c (clear_bad_block_proc):
2462 dblist.c (ext2fs_add_dir_block):
2463 icount.c (insert_icount_el):
2464 irel_ma.c (ima_put):
2465 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
2466 pass the old size of the memory to be resized to
2467 ext2fs_resize_mem().
2469 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2471 * Makefile.in: Change to use new installation directory variables
2472 convention. Fix uninstall rules to take $(DESTDIR) into
2475 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
2477 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
2478 with 32 bit longs, then we need to manually define __s64
2479 and __u64, since the current kernel header files don't
2480 define these if __STRICT_ANSI__ is defined. This is a
2481 problem if we are compiling with full GCC warnings, since
2482 we do need 64 bit support.
2484 * Makefile.in (OBJS): Remove bmove.o from files to be built,
2485 since we're not using ext2fs_move_blocks() and there
2486 is some question as to its usefulness in its current
2489 * bmap.c (block_bmap): Remove unused function.
2491 * bmove.c (process_block): Fix -Wall warning.
2493 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
2495 * block.c (ext2fs_block_iterate3): Make the ref_offset field
2496 contain the offset into the inode.i_blocks array when
2497 ref_block is zero. Since we haven't done a formal
2498 release of e2fsprogs since block_iterate2 was first
2499 introduced, I removed block_iterate2, and renamed
2500 block_iterate3 to be block_iterate2.
2502 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
2503 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
2504 use of block_iterate and block_iterate2 to
2505 block_iterate2 with the new prototype for the
2506 interator function. (using blkcnt_t forr blockcount)
2508 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
2510 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
2511 s_prealloc_blocks, s_prealloc_dir_blocks). Added
2512 conditional defines of new features COMPAT_DIR_PREALLOC,
2513 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
2514 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
2515 the library to declare that we support COMPAT_DIR_PREALLOC,
2516 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
2518 * fileio.c: Rename function ext2fs_file_llseek to be
2519 ext2fs_file_lseek, which is more accurate.
2521 * block.c: Add new function ext2fs_block_iterate3 which calls
2522 the iterator function with the blockcount argument of
2523 type blkcnt_t. This version of the function is
2524 allowed to handle large files; the other fucntions are
2527 * ext2fs.h: Add new type blkcnt_t
2529 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
2531 * block.c (ext2fs_block_iterate2): Fix bug where the block count
2532 field wasn't getting correctly incremented for sparse
2533 files when the indirect or doubly-indirect block
2534 specified in the inode was zero.
2536 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2538 * unlink.c (unlink_proc):
2539 * lookup.c (lookup_proc):
2540 * link.c (link_proc):
2541 * get_pathname.c (get_pathname_proc):
2542 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
2543 from dirent->name_len, so it can be used for other
2546 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
2547 and indicate that we have support for this incompatible
2550 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2552 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
2554 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2556 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
2557 number of directories when the block group information is
2560 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
2562 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
2563 inode table is missing so that we catch the case where the
2564 first block group is missing.
2566 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
2569 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2571 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
2573 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
2575 * test_io.c (test_flush): Add a debugging printf when the flush
2578 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
2579 read in, return right away.
2581 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2583 * bitops.h: Don't try to do i386 inline asm functions if the
2586 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
2587 instead of linux/types.h, and e2_bitops.h instead of
2590 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
2593 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2595 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
2596 so that we don't need to call get_next_blockgroup() the
2597 first time around. Saves a bit of time, and prevents us
2598 from needing to assign -1 to current_group (which is an
2601 * icount.c (insert_icount_el): Cast the estimated number of inodes
2602 from a float to an ino_t.
2604 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
2605 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

2614 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
2615 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
2616 defined, then assume all of the
2617 ext2-specific header files are in a flat directory.
2619 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
2620 all assignments from void * to be compatible with C++.

2624 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
2625 make sure the contents of the disk are flushed to disk.
2627 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2629 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
2630 avoid C++ namespace clash.
2632 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to

2641 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2643 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
2644 paranoid about validating the directory counts from the
2645 block group information.
2647 * all files: Don't include stdlib.h anymore; include it in
2648 ext2_fs.h, since that file requires stdlib.h
2650 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2652 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
2653 bitmap is loaded, and return an error if it is not.
2654 (expand_dir_proc): Only use ext2fs_write_dir_block when
2655 writing a directory block, not when writing out a fresh
2658 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2660 * Makefile.in, tst_getsize.c: Added new file which is used to test

2673 Fri Oct 31 12:16:52 1997 <tytso@EDT.MIT.EDU>
2675 * bitops.c (ext2fs_warn_bitmap, ext2fs_warn_bitmap2): Don't call
2676 com_err if OMIT_COM_ERR is defined.
2678 Thu Oct 30 11:33:57 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2680 * Rename new error codes to _ET_ in them for consistency.
2682 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2684 * [all files, basically]: Added definition of ext2fs_get_mem,
2685 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
2686 changed all library routines to use these wrapper functions.
2688 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
2689 instead of the system error messages.
2691 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
2694 * ext2fs.h: Added function declarations and constants for bmap.c
2697 * ext2_err.et.in: Added new error messages EXT2_FILE_RO and
2698 EXT2_ET_MAGIC_EXT2_FILE
2700 * Makefile.in: Added files bmap.c and fileio.c, and temporarily
2701 commented out brel_ma.c and irel_ma.c
2703 * bmap.c: New file which maps a file's logical block number to its
2704 physical block number.
2706 * fileio.c: New file which implements simple file reading and
2709 * alloc.c (ext2fs_alloc_block): New function which allocates a
2710 block, zeros it, and updates the filesystem accounting
2711 records appropriately.
2713 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2715 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
2716 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
2717 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
2719 * Change various library files to use these functions instead of
2720 EINVAL, ENOENT, etc.
2722 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2724 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
2725 need to declare llseek().
2727 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2729 * Rename io.h to be ext2_io.h (avoid namespace collisions)
2731 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
2733 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

2767 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2769 * io.h: Change the prototype of ext2fs_llseek() to use int's
2770 instead of unsigned int's.
2772 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
2773 to make life easer for GNU Libc 2.
2775 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
2776 filesystem has its bitmaps stored as 32-bit words with bit
2777 0 as the LSB of each word. Thus a bitmap with only bit 0
2778 set would be, as a string of bytes, 00 00 00 01 00 ... To
2779 cope with this, we byte-reverse each word of a bitmap if
2780 we have a big-endian filesystem, that is, if we are *not*
2781 byte-swapping other word-sized numbers.
2783 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

2801 and size_t where appropriate.
2803 * closefs.c (ext2fs_flush): Use dgrp_t instead of int where
2806 * openfs.c (ext2fs_open):
2807 * check_desc.c (ext2fs_check_desc): Use blk_t instead of int where

2813 * initialize.c (ext2fs_initialize):
2814 * brel_ma.c: Fix to make be 16-bit safe.
2816 * link.c (ext2fs_link):

2830 * bb_inode.c (set_bad_block_proc): Add #pragma argsused for Turbo C.
2832 * alloc.c (ext2fs_new_inode): Use ino_t instead of int for the
2835 * get_pathname.c: Use ino_t instead of int where appropriate.
2837 * ext2fs.h: Make the magic structure element be errcode_t instead
2840 * alloc.c alloc_tables.c badblocks.c bb_compat.c bb_inode.c
2841 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
2842 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c
2843 dirblock.c dupfs.c expanddir.c freefs.c get_pathname.c
2844 icount.c initialize.c inline.c inode.c irel_ma.c link.c
2845 llseek.c lookup.c mkdir.c namei.c newdir.c read_bb.c
2846 read_bb_file.c rs_bitmap.c rw_bitmaps.c swapfs.c
2847 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
2848 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
2850 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2852 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
2853 is zero, then return EXT2_IO_LLSEEK_FAILED.
2855 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
2857 * Release of E2fsprogs 1.11
2859 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2861 * dblist.c (ext2fs_dblist_count): Added new function which returns
2862 the number of directory blocks in dblist.
2864 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2866 * unix_io.c (unix_flush): Make the io_channel flush function do a
2867 fsync to flush the kernel buffers to disk.
2869 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2871 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
2872 current inode number wasn't being set by the
2873 goto_blockgroup function.
2875 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2877 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
2878 of blocks which need to be moved, and moves those blocks
2879 to another location in the filesystem.
2881 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
2882 bitmap, make sure all of the new parts of the bitmap are
2885 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2887 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
2888 wasn't being returned to the caller.
2890 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
2891 ext2fs_allocate_group_table() which sets the group tables
2892 for a particular block group. The relevant code was
2893 factored out of ext2fs_allocate_tables().
2895 * dblist.c (make_dblist): Adjust the initial size of the directory
2896 block list to be a bit more realistic (ten plus twice the
2897 number of directories in the filesystem).
2899 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2901 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
2902 ext2fs_badblocks_list_test would test the list (and exceed
2903 array boundaries) if there were no bad blocks on the bad
2904 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
2906 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2908 * Release of E2fsprogs version 1.10
2910 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2912 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
2913 inode and block bitmaps based on the RAID 0 stride
2914 parameter (which is passed by mke2fs).
2916 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
2917 mke2fs to communicate the stride length to
2918 ext2fs_allocate_tables()
2920 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2922 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
2923 systems. (We can't assume that the new filesystem types
2926 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2928 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
2929 allocate the inode and block bitmaps inside block group at
2932 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2934 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
2935 filesystem has no free blocks, ext2fs_new_block would loop
2938 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
2940 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
2941 free if refcount goes to zero.
2943 * inode.c (create_icache): Initialize refcount to 1.
2945 * ext2fsP.h: Added refcount to ext2_inode_cache
2947 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
2950 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
2951 badblocks structure.
2953 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2955 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
2957 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
2959 (unix_close, test_close): Decrement the refcount and only
2960 close the io_channel if the refcount goes to 0.
2962 * io.h: Add refcount to the io_channel structure. Add new macro
2963 interface io_channel_bumpcount() to bump the refcount.
2965 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2967 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
2968 cache in the filesystem handle, instead of the inode cache
2969 in a static variable.
2971 * freefs.c: Added static function to free the inode cache (called by
2974 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
2976 * ext2fs.h: Added pointer to the inode_cache structure.
2978 * block.c (block_iterate_ind, block_iterate_dind,
2979 block_iterate_tind): If there are holes in the indirect,
2980 doubly indirect, or triply indirect blocks, increment the
2981 block count field automatically.
2983 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2985 * Release of E2fsprogs version 1.09
2987 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2989 * version.c (ext2fs_parse_version_string): Check the passed in
2990 version string (instead of the hard-coded one).
2992 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
2993 greater filesystem size, clamp it to prevent allocating a
2994 block or inode bitmap beyond the filesystem.
2996 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
2997 overhead calculation was accidentally removed.
2999 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3001 * Release of E2fsprogs version 1.08
3003 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3005 * dblist.c (ext2fs_set_dir_block): New function which sets the
3006 block of a dblist entry, given the directory inode and
3009 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3011 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
3012 inode bitmaps at staggered locations across the block
3013 groups, to avoid concentrating the bitmaps on a small
3014 number of disks when using striped RAID arrays.
3016 * initialize.c (ext2fs_initialize): By default, choose the maximum
3017 possible number of blocks per group (based on the size of
3018 the bitmaps in the blocksize).
3020 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3022 * initialize.c (ext2fs_initialize): Add support for
3023 EXT2_COMPAT_SPARSE_SUPER feature.
3025 * closefs.c (ext2fs_bg_has_super): New function to determine
3026 whether or a particular block group should have a
3027 superblock and block group descriptor. Used for the
3028 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
3029 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
3030 or not the superblock should be written out for the block
3033 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
3034 for sparse duplicate superblocks.
3036 * version.c (ext2fs_get_library_version): New function which
3037 returns the library version.
3039 * version.c (ext2fs_parse_version_string): New function which
3040 parses a version string and returns a version number,
3041 so application programs can compare version numbers as
3044 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3046 * icount.c (ext2fs_create_icount): Change function so that it also
3047 takes a new argument which contains a "hint" icount
3048 structure. This "hint" icount allows the create function
3049 to set up the sorted list in advance. This reduces
3050 significantly the amount of data moving needed to insert
3051 these inodes into the list later.
3053 * icount.c (ext2fs_icount_validate): New function which validates
3054 that the icount structure's rep invariant.
3056 * icount.c (get_icount_el): Completely revamped implementation
3057 to subsume put_icount_el(). Put_icount_el() used to
3058 use an O(N) implementation to insert in the middle
3059 of the icount list. It now uses a O(ln N) to search
3060 for where the icount should be inserted, and then uses
3061 a memcpy to move the list down (instead of a for loop).
3063 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
3064 ext2fs_icount_increment, ext2fs_icount_decrement): Check
3065 to see if the inode is within bounds; if it isn't, return
3068 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
3069 when a bad inode number is passed to test_generic_bitmap
3070 to be EXT2FS_TEST_ERROR instead of the wrong
3071 EXT2FS_UNMARK_ERROR.
3073 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
3075 * Release of E2fsprogs version 1.07
3077 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3079 * Makefile.in (ELF_VERSION): Change version to be 2.2
3081 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3083 * alloc.c (ext2fs_get_free_blocks): Change routine to use
3084 ext2fs_fast_test_block_bitmap_range().
3086 * bitops.h (ext2fs_fast_test_block_bitmap_range,
3087 ext2fs_test_block_bitmap_range: New inline functions which
3088 test to see whether a contiguous range of blocks is
3091 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3093 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
3094 use ext2fs_badblocks_* instead of badblocks_*
3096 * bb_compat.c: New file which translates between old badblocks_*()
3097 names to ext2fs_badblocks_*()
3099 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
3100 link.c (since e2fsck doesn't use ext2fs_unlink()).
3102 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
3103 bitmap resizing routine moved from bitmaps.c, since e2fsck
3104 doesn't need to use this function.
3106 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
3107 since e2fsck only needs ext2fs_lookup.
3109 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3111 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
3112 already set; this is needed so that programs like dump
3113 which use the inode scan functions will deal with
3114 filesystems that have bad blocks in the inode table.
3116 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3118 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
3119 Moved to ext2fsP.h, since it doesn't need to be part of
3120 the public interface.
3122 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
3124 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3126 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
3127 directory block list abstraction. (Code moved from
3130 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
3131 to inode.c (since no one else should be peeking inside it!)
3133 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
3135 * openfs.c (ext2fs_open): Check the feature set in the ext2
3136 superblock, and refuse to open filesystems if they contain
3137 incompatible features. (Can be overriden with the
3140 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3142 * block.c (ext2fs_block_iterate2): Added new function
3143 ext2fs_block_iterate2 which changes the function
3144 signature of the callback function to include the
3145 referencing block and offset.
3147 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
3148 ext2fs_inode_scan_goto_blockgroup which allows an
3149 application to jump to a particular block group while
3150 doing an inode scan.
3152 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3154 * dirblock.c: Include string.h, since we use memcpy().
3156 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3158 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
3159 a long not an int; this doesn't matter on i386 machines,
3160 but it does on Alpha's.
3162 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3164 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
3165 table pointer is NULL, then return an error indicating
3166 that the inode table is missing.
3167 (get_next_blockgroup, get_next_blocks,
3168 ext2fs_get_next_inode): Don't treat a missing inode table
3169 as permanent error. Return MISSING_INODE_TABLE, but as an
3170 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
3172 * rw_bitmaps.c (ext2fs_write_block_bitmap,
3173 ext2fs_write_inode_bitmap): If the inode or block bitmap
3174 block is zero, then don't write out the inode or block
3175 bitmap. The idea here is to avoid stomping on the
3177 (read_bitmaps): If the inode or block bitmap block is
3178 zero, then fill in that portion of the inode or block
3179 bitmap with all zeros.
3181 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
3182 blocks in inode table when the inode table size is
3183 non-standard (and can therefore span blocks).
3185 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3187 * alloc.c (ext2fs_new_block): Fix fencepost error in
3188 ext2fs_new_block; make sure we don't try to allocate the
3189 first block beyond the end of the filesystem.
3191 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3193 * inode.c (check_for_inode_bad_blocks): New function called by
3194 get_next_blocks() to avoid reading in bad blocks marked in
3195 fs->badblocks. Inodes located in bad blocks are returned
3196 by ext2fs_get_next_inode() returns the error code
3197 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
3199 * alloc_tables.c (ext2fs_allocate_tables): New function which
3200 performs the part of mke2fs's job of allocating the

3211 inode table to get_next_blocks().
3213 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
3215 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
3216 blocks to the badblock list in sorted order. This allows
3217 badblocks_list_test to be coded using a binary search for
3220 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3222 * Release of E2fsprogs version 1.06

3226 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
3227 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
3230 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
3231 set, then only write out the master superblock.
3233 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3235 * block.c (ext2fs_block_iterate): Fixed bug which caused
3236 block_iterate to fail to handle HURD created filesystems;
3237 it tested the inode translator field before the inode was
3240 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3242 * initialize.c (ext2fs_initialize): Make sure the description for
3243 the inode bitmap is set correctly.

3258 * namei.c (ext2fs_namei_follow): New function which follows
3259 symbolic link (if any) at the target.
3261 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3263 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
3264 for shortcut function fs->read_inode() and fs->write_inode().

3271 * namei.c (ext2fs_follow_link): New function.
3272 (ext2fs_namei): Extended to have support for chasing
3273 symbolic links. ext2fs_namei() still returns an inode
3274 which is a symbolic link. Symbolic links are only chased
3275 while resolving the containing directory. To chase
3276 symbolic links of the final result, use
3277 ext2fs_follow_link().
3279 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3281 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.

3288 * initialize.c (ext2fs_initialize): On systems where the byte
3289 order is not i386 compatible, set the swap_byte flag.
3291 * inode.c (inocpy_with_swap): Check to see if inode contains a
3292 fast symlink before swapping the inode block fields. This
3293 required adding a new argument to inocpy_with_swap to
3294 determine whether the mode field is in host order or not.
3296 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3298 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
3299 the sparc, if EXT2_STD_BITOPS set, use the standard
3300 i386-compatible bitmask operations, instead on the
3301 non-standard native bitmask operators.
3303 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3305 * block.c (ext2fs_block_iterate): Cause block iterator to return
3306 the HURD translator block (along with everything else).
3307 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
3308 iterator, then don't return any meta data blocks
3309 (including the HURD translator).
3311 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3313 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
3315 * uuid.c: New file, containing UUID utility functions.
3317 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3319 * ext2fs.h: Add a definition of the "real" ext2 superblock.
3321 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3323 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
3325 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3327 * openfs.c (ext2fs_open): If the blocksize in the superblock is
3328 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
3329 that's a basic value that must be correct for the rest of
3330 the library to work.
3332 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
3335 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

3346 Change the m68k bit numbering for bitmasks to match with
3347 the bit numbering used by all other ext2 implementations.
3349 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
3351 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
3352 ext2fs_open_inode_scan): Support dynamically-sized inodes.
3354 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>

3374 when trying to determine its size.
3376 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
3378 * Release of E2fsprogs version 1.02

3384 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3385 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
3386 to avoid conflicts with with kernel include files. Also
3387 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
3390 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
3392 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
3394 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
3395 s_def_resuid and s_def_resgid for backwards compatibility.
3397 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

3410 * Makefile.in: Added support for BSD shared libraries.
3412 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
3415 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
3417 * unix_io.c (unix_open): Add a double check; if the passed in name
3418 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
3420 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
3422 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

3429 * getsize.c (ext2fs_get_device_size): Add support for reading the
3430 partition size from a BSD disk label.
3432 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3434 * getsize.c (ext2fs_get_device_size): New function that determins
3435 the size of a device. Used by mke2fs and e2fsck.

3444 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
3445 Move these functions to freefs.c.
3447 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
3448 descriptors shadow memory to keep purify quiet. (This
3449 also has the nice benefit that the unused portion of the
3450 shadow descriptors are zeroed out.)
3452 * dirblock.c (ext2fs_write_dir_block): We need to use
3453 dirent->rec_len *before* it's byteswapped to find the
3454 location of the next directory structure!
3456 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
3457 cause ext2fs_new_inode to loop infinitely if we're trying
3458 to allocate an inode in group #0 and there are no free
3459 inodes at all in the system.
3461 * closefs.c: #include <errno.h> if it exists.
3463 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3465 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

3482 file containing functions for reading and writing
3483 directory blocks (byte swapping if necesssary)
3485 * block.c (block_iterate_ind, block_iterate_dind,
3486 block_iterate_tind): Byte swap the block addresses if
3487 EXT2_SWAP_BYTES is set (and swap them back before writing
3490 * inode.c (inocpy_with_swap): New function.
3491 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
3492 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
3494 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
3495 the superblock and group descriptors before writing it out.
3497 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
3498 then set the EXT2_SWAP_BYTES and byte-swap the superblock
3499 and group descriptors.
3501 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
3502 to desp ext2 filesystem structures.
3504 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
3505 supplied by Pete A. Zaitcev so that the C language
3506 versions of these functions are more portable. They will
3507 now work on both little and big endian systems, and the
3508 assumption that 32-bit integers are used is gone.
3510 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
3511 doing byte swapping.
3513 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
3514 byte swapping should take place.
3516 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

3527 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
3528 if the magic number is correct, it will be allocated.
3530 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
3532 * block.c (block_iterate_ind, block_iterate_dind,
3533 block_iterate_tind): Don't recompute block_nr each loop;
3534 just increment it! Factor check of BLOCK_FLAG_APPEND out
3535 of the loop. Factor mask of BLOCK_CHANGED into changed
3536 variable out of the loop. (block_iterate_ind, in
3537 particular, gets called a lot, so every little
3538 optimization helps.)
3540 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
3542 * block.c (block_iterate_ind, block_iterate_dind,

3549 ext2fs_fast_test_inode_bitmap): Add fast version of these
3550 functions, which don't do range checking.

3554 ext2fs_get_inode_bitmap_end): Add new accessor functions
3555 which return the start and end points of the bitmaps.
3557 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
3559 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
3560 instead of llseek. The errno if the offset is too large
3561 and lseek is not supported should be EINVAL, not -EINVAL.
3563 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
3565 * Makefile.in: Added support for ELF shared libraries.
3566 Fixed typos in the compilation rules.
3567 (distclean): Added Makefile.
3569 * llseek.c (llseek): New function, if llseek() does not exist in the
3571 (ext2_llseek): Changed to call llseek().
3573 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3575 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.

3581 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
3582 the S_*, which are normally defined in <sys/stat.h>. This
3583 allows us to compile e2fsprogs on a non-Linux system,
3584 which may have a different value for S_IFDIR.
3586 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3588 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
3589 this is a user-mode application!
3591 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
3593 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
3594 __linux__ so that non-linux systems won't see it.
3596 * alloc.c: Include <errno.h> if possible.
3597 * badblocks.c: Ditto.
3598 * bb_inode.c: Ditto.
3601 * expanddir.c: Ditto.
3602 * get_pathname.c: Ditto.
3603 * initialize.c: Ditto.
3610 * rw_bitmaps.c: Ditto.
3613 * Makefile.in: Rewritten to conform to GNU coding standards and
3614 support separate compilation directories.
3616 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
3618 * initialize.c (ext2fs_initialize): Don't allow more than one
3619 bitmaps's worth of inodes in a group.
3621 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
3623 * llseek.c (ext2_llseek): Added error checking to the llseek()
3624 compat code to protect against overflow. This only
3625 applies to 1.0 and early 1.1 kernels, which don't support
3626 the llseek() system call.
3628 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
3630 * unix_io.c (unix_open): Initialize the read_error and write_error
3631 io_channel pointers to be null.
3633 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
3634 found, clear it but don't try to update the filesystem
3635 accounting information, since that's hopeless anyway.
3637 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
3638 bloblock_iterate_tind): Check to see if the indirect blocks are
3639 valid before trying to read them.

3645 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
3646 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
3647 illegal block or inode number is passed in, return instead
3648 of trying to test, set, or clear the bit.
3650 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
3652 * Makefile: Added a dummy install target in case shared libraries

3662 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
3663 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
3664 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
3665 ext2fs_free_block_bitmap): Add magic number checking for
3666 the inode and block bitmaps.
3668 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
3669 magic number for a block bitmap instead of an inode bitmap.
3671 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
3672 magic number checking for the inode_scan structure.
3674 * badblocks.c (badblocks_list_free, badblocks_list_add,
3675 badblocks_list_test, badblocks_list_iterate_begin,
3676 badblocks_list_iterate, badblocks_list_iterate_end): Add
3677 magic number checking for the badblocks_list and
3678 badblocks_iterate structures.
3680 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
3681 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
3682 unix_write_blk, unix_flush): Add magic number checking
3683 both for io_channel structure and unix_private_data
3686 * openfs.c (ext2fs_open): Add check for io_manager structure's
3689 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
3690 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
3691 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
3692 * read_bb.c (ext2fs_read_bb_inode):
3693 * read_bb_file.c (ext2fs_read_bb_FILE):
3694 * newdir.c (ext2fs_new_dir_block):
3695 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
3696 * link.c (ext2fs_link, ext2fs_unlink):
3697 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
3698 ext2fs_write_inode, ext2fs_get_blocks,
3699 ext2fs_check_directory):
3700 * get_pathname.c (ext2fs_get_pathname):
3701 * expanddir.c (ext2fs_expand_dir):
3702 * block.c (ext2fs_block_iterate):
3703 * bitmaps.c (ext2fs_allocate_inode_bitmap,
3704 ext2fs_allocate_block_bitmap):
3705 * bb_inode.c (ext2fs_update_bb_inode):
3706 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
3707 * check_desc.c (ext2fs_check_desc):
3708 * closefs.c (ext2fs_close, ext2fs_flush):
3709 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
3714 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
3715 openfs.c into its own file.
3717 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
3718 structure magic numbers.
3720 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
3721 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
3722 someone uses the -b option to specify the use of the backup
3723 superblock --- this usually means that the main superblock is
3727 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
3728 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
3729 revision level to the superblock.
3731 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
3738 * initialize.c: Completely revamped the inode and block bitmap
3739 structures, so that they can be better chance of being extensible
3740 in a shared library. They are now their own type, instead of
3741 being a char *. Also, the function signatures of
3742 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
3743 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
3744 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
3745 changed to eliminate the ext2_filsys argument, since it is no
3748 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
3750 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
3751 system call if available.
3753 * llseek.c: new file. This is the stub calling the llseek system
3754 call which allows supports for 2GB+ file systems.
3756 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
3757 the creator operating system.
3759 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
3761 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
3762 the group descriptor statistics in addition to everything else.
3763 This relieves mke2fs of the responsibility of doing it.
3765 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
3766 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
3767 not the generic C function equivalents should be included or not.
3769 * openfs.c (ext2fs_open): If a superblock is specified, then use
3770 the backup group descriptors that go along with this superblock,
3771 instead of using the primary group descriptors. This allows
3772 e2fsck to recover filesystems where the primary group descriptors
