12 when reading uid/gid, on platforms that support it.
14 2007-04-19 Theodore Tso <tytso@mit.edu>
16 * ext2_fs.h, swapfs.c (ext2fs_swap_inode_full): Rename the
17 l_i_reserved1 field to be l_i_version (to be used for the
18 high 32 bits of the 64-bit inode version number).
20 2007-04-18 Theodore Tso <tytso@mit.edu>
22 * getsize.c (ext2fs_get_device_size): Make sure we don't leak a
23 file descriptor in some error cases.

35 when checking really large filesystems.
37 * ext2_err.et.in: Add new TDB error codes.
39 * icount.c, Makefile.in: Add a regression test suite for the
42 2007-04-04 Jim Garlick <garlick@llnl.gov>

53 2007-04-02 Theodore Tso <tytso@mit.edu>
55 * icount.c (get_icount_el): Prevent floating point precision
56 errors on really big filesystems from causing the search
57 interpolation algorithm loop forever. (Addresses Debian
60 2007-03-21 Theodore Tso <tytso@mit.edu>
62 * imager.c (ext2fs_image_inode_write), inode.c
63 (ext2fs_write_inode_full): Fix memory leak on error return
64 (when the inode table is missing).
66 2006-11-30 Theodore Tso <tytso@mit.edu>
68 * ext2_fs.h (struct ext4_group_desc): Fix missing bg_pad which
69 made the structure too small.
71 2006-11-14 Theodore Tso <tytso@mit.edu>
73 * namei.c (open_namei): Rename internal variable basename to
74 base_name to prevent gcc -Wall complaints.
76 * kernel-jbd.h (tid_gt, tid_geq): Add function declaration to
77 avoid gcc -Wall complaints.
79 * ext2_ext_attr.h (EXT2_EXT_ATTR_PAD): Make unsigned to fix gcc
82 * bitops.h (ext2fs_test_bit): Add missing const to fix gcc -Wall
85 * ext2fs.h (ext2fs_get_mem, ext2fs_free_mem): Avoid type punning
86 which causes problems on the ARM processor. (Addresses
89 2006-11-12 Theodore Tso <tytso@mit.edu>
91 * ext2_fs.h (EXT2_FLAG_SOFTSUPP_FEATURES), openfs.c
92 (ext2fs_open2): Add flag which indicates that it's OK to
93 open a filesystem which has features which are only
94 partially supported by e2fsprogs.
96 * ext3_extents.h, ext2fs.h: Check in ext4 extent headers into the
97 source tree, in preparation for adding full extent support.
99 * unix_io.c (unix_flush): Allow offsets greater than 2G.
100 (Addresses SourceForge Bug #1547922)
102 2006-11-11 Theodore Tso <tytso@mit.edu>
104 * dirhash.c (str2hashbuf, ext2fs_dirhash): Add support for
105 calculating the unsigned version of the directory hash.
107 * initialize.c (ext2fs_initialize): Set the dirhash
108 signed/unsigned hint in s_flags.
110 * swapfs.c (ext2fs_swap_super): Byte swap the s_flags superblock
113 * ext2_fs.h: Define a new superblock field, s_flags, which is used
114 to store a signed vs. unsigned dirhash hint. Define new
115 HTREE hash algorithm numbers to pass to userspace if the
116 unsigned algorithm are required.
118 * swapfs.c (ext2fs_swap_super):
119 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE,
120 which adds s_min_extra_isize and s_want_extra_isize fields
121 to superblock, which allow specifying the minimum and
122 desired i_extra_isize fields in large inodes
123 (for nsec+epoch timestamps, potential other uses).
124 Needs RO_COMPAT flag handling, needs e2fsck support,
125 patch complete, little testing.
127 * swapfs.c (ext2fs_swap_super):
128 ext2_fs.h: Add definition of EXT4_FEATURE_INCOMPAT_64BIT,
129 which adds supports for 64-bit block count fields in the
130 superblock (s_blocks_count_hi, s_free_blocks_count_hi),
131 large group descriptors (s_desc_size), extents with high
132 16 bits (ee_start_hi, ei_leaf_hi), inode ACL (i_file_acl_hi)
134 * ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_DIR_NLINK,
135 which allow directories to have > 65000 subdirectories
136 (i_nlinks) by setting i_nlinks = 1 for such directories.
137 RO_COMPAT protects old filesystems from unlinking such
138 directories incorrectly and losing all files therein.
140 * swapfs.c (ext2fs_swap_group_desc):
141 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
142 which adds a crc16 checksum in the group descriptor,
143 (s_uuid[16] | __u32 group | ext3_group_desc
144 (excluding gd_checksum itself)). This allows the kernel
145 to more safely manage UNINIT groups. Also adds an
146 bg_itable_unsued which indicates how many inodes are
147 uninitialized in the block group.
149 * swapfs.c (ext2fs_swap_inode_full):
150 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_HUGE_FILE,
151 which changes i_blocks to be in units of s_blocksize units
152 instead of 512-byte sectors, use l_i_frag and l_i_fsize as
155 2006-10-02 Eric Sandeen <esandeen@sandeen.net>
157 * getsize.c (ext2fs_get_device_size): Check to make sure that the
158 number of blocks doesn't overflow the retblocks return
159 parameter for regular files using stat64().
161 2006-10-01 Theodore Tso <tytso@mit.edu>
163 * bitops.h (ext2fs_swab32): Only include ext2fs_swab32() if
164 EXT2FS_ENABLE_SWAPFS is defined.
166 2006-08-30 Eric Sandeen <esandeen@redhat.com>
168 * initialize.c (ext2fs_initialize): Make sure inode count does
169 not overflow 32 bits.
171 2006-08-30 Eric Sandeen <esandeen@redhat.com>
173 * alloc_tables.c (ext2fs_allocate_group_table):
174 * check_desc.c (ext2fs_check_desc):
175 Use new inlines to calculate group first & last blocks.
177 Create new inlines to calculate first/last group blocks.
179 2006-08-30 Eric Sandeen <esandeen@redhat.com>

196 2006-08-30 Eric Sandeen <esandeen@redhat.com>
198 * check_desc.c (ext2fs_check_desc): avoid overflows when iterating
199 over group descriptors on very large filesystems.
201 2006-08-30 Theodore Tso <tytso@mit.edu>
203 * bitmaps.c (ext2fs_set_bitmap_padding): Fix potential overflow
204 problems when the number of blocks is close to 2**31.
206 * ext2fs.h (ext2fs_div_ceil): Add new function which safely
207 calculates an integer division where the result is always
208 rounded up while avoiding overflow errors.
210 * initialize.c (calc_reserved_gdt_blocks, ext2fs_initialize):
211 * openfs.c (ext2fs_open2): Use ext2fs_div_ceil() instead of a
212 using an open-coded expression which was subject to
215 2006-08-06 Andreas Dilger <adilger@clusterfs.com>
217 * bitops.h (ext2fs_cpu_to_le32, ext2fs_le64_to_cpu,
218 ext2fs_swab64): Add 64-bit byte swapping functions
220 2006-08-05 Theodore Tso <tytso@mit.edu>
222 * ext2_fs.h (EXT4_EXTENTS_FL): Rename EXT3_EXTENTS_FL to
223 EXT4_EXTENTS_FL, and add EXT4_EXTENTS_FL to user visible
226 2006-07-15 Theodore Tso <tytso@mit.edu>
228 * ext2fs.h: Remove unneeded #ifdef since EXT2_DYNAMIC_REV is
229 always defined in the e2fsprogs-provided ext2_fs.h
231 2006-05-21 Theodore Tso <tytso@mit.edu>
233 * openfs.c (ext2fs_open2): Fix type warning problem with sizeof()
235 2006-05-12 Theodore Tso <tytso@mit.edu>
237 * alloc_tables.c (ext2fs_allocate_group_table): When allocating
238 space for the RAID filesystems with the stride parameter,
239 place each portion of the group's inode table right up
240 after the superblock (if present) in order to minimize
241 fragmentation of the freespace.
243 2006-05-08 Theodore Tso <tytso@mit.edu>
245 * rw_bitmaps.c (write_bitmaps, read_bitmaps): Added support for
246 lazy blockgroups. If a block group has flags indicating
247 that its block or inode data structures have not been
248 initialized, skip reading or writing that portion of the
251 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode_full): When
252 scanning a filesystem with lazy blockgroups, skip
253 uninitialized portions of the inode table when iterating
254 over the block group.
256 * swapfs.c (ext2fs_swap_group_desc): Byte swap the bg_flags field.
258 * ext2fs.h: Define the a new internal flag, EXT2_SF_DO_LAZY, so
259 that the inode interator knows compat_lazy_bg feature is
260 enabled. Declare that this version of e2fsprogs supports
261 the EXT2_FEATURE_COMPAY_LAZY_BG feature.
263 * ext2_fs.h (struct ext2_group_desc): Use the bg_pad field for
264 bg_flags, and define the flags EXT2_BG_INODE_UNINIT and
265 EXT2_BG_BLOCK_UNINIT. These flags are only honored if
266 EXT2_FEATURE_COMPAT_LAZY_BG feature is enabled (also
269 2006-04-23 Theodore Ts'o <tytso@mit.edu>
271 * rw_bitmaps.c (write_bitmaps, ext2fs_write_inode_bitmap,
272 ext2fs_write_block_bitmap, ext2fs_write_bitmaps): Reduce
273 disk seeks by writing the inode and block bitmaps in an
276 2006-04-09 Theodore Ts'o <tytso@mit.edu>
278 * ext2_types.h.in, Makefile.in, tst_types.c: Use the asm_types.h
279 file to define the __[us]{8,16,32,64} types. Add a
280 tst_types program to make sure the types are correct.
282 2006-04-04 Theodore Ts'o <tytso@mit.edu>
284 * mkjournal.c (ext2fs_add_journal_inode): If the filesystem is
285 opened in exclusive mode, then device will be busy by
286 definition, so don't return -EBUSY. This caused mke2fs -j
287 to fail on the 1.39-WIP (29-Mar-2006) release. (Addresses
290 2006-03-29 Theodore Ts'o <tytso@mit.edu>
292 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit): Fix the constraints
293 so that GCC knows that the ext2fs_set/clear_bit reads and
296 2006-03-25 Theodore Ts'o <tytso@mit.edu>
298 * Makefile.in: Check the bitfield operations much more carefully,
299 and arrange to have tst_bitops run from "make check"
301 * tst_bitops.c: Enahce tst_bitops program so that it is much more
302 thorough in testing bit optations.
304 * bitops.h: Add new functions ext2fs_fast_set_bit() and
305 ext2fs_fast_clear_bit() and make the x86 functions 32-bit
306 clear. Change the fast inode and block mark/unmark
307 functions to use ext2fs_fast_set/get_bit()
309 2006-03-18 Theodore Ts'o <tytso@mit.edu>
311 * ext2fs.h (EXT2_FLAG_EXCLUSIVE): Define new flag which requests
312 that the io_channel be opened in exclusive mode.
314 * openfs.c (ext2fs_open2), initialize.c (ext2fs_initialize): If
315 EXT2_FLAG_EXCLUSIVE is passed to ext2fs_open or
316 ext2fs_initialize, then pass IO_FLAG_EXCLUSIVE to the
317 io_channel open routine.
319 * ext2_io.h (IO_FLAG_EXCLUSIVE), unix_io.c (unix_open): Add new
320 io_channel open flag, IO_FLAG_EXCLUSIVE, which requests
321 that the device be opened in exclusive (O_EXCL) mode.
323 * ext2fs.h: Fix documentation so that BLOCK_FLAG_TRAVERSE is
324 BLOCK_FLAG_DEPTH_TRAVERSE. (Addresses Debian Bug #351268)
326 2006-03-17 Theodore Ts'o <tytso@mit.edu>
328 * initialize.c (calc_reserved_gdt_blocks): Fix a signed vs
329 unsigned problem which caused mke2fs -O resize_inode to
330 bomb out on large filesystems. (Addresses Debian Bug
333 * ext2_fs.h (EXT2_IOC_GETVERSION_NEW, EXT2_IOC_SETVERSION_NEW,
334 EXT2_IOC_GROUP_EXTEND, EXT2_IOC_GROUP_ADD): Add ioctl

340 subdirectories are created before creating all of the
343 2005-12-10 Theodore Ts'o <tytso@mit.edu>
345 * res_gdt.c (ext2fs_create_resize_inode): Fix type-punning warning.
347 * read_bb_file.c (ext2fs_read_bb_FILE): Use a data structure
348 instead of stuffing a function pointer dirctly into a void
349 pointer, since that isn't portable.
351 * mkjournal.c (ext2fs_add_journal_inode): Fix possiblely
352 uninitialized use of variable warning.
354 * initialize.c (calc_reserved_gdt_blocks): Fix signed vs. unsigned
357 * ext2fs.h: Make the type of the 'now' field to be time_t to avoid
358 gcc -Wall complaints.
360 * bitops.h (ext2fs_find_first_bit_set): Fix signed vs unsigned
363 * tst_badblocks.c (file_test_invalid): Add test which confirms
364 proper detection of invalid block numbers in
365 ext2fs_read_bb_FILE().
367 2005-11-20 Theodore Ts'o <tytso@mit.edu>
369 * bitops.h: We no longer have the sparc assembly code in the
370 header file any more, so we shouldn't set
371 _EXT2_HAVE_AS_BITOPS_. This would break compiles on the
372 sparc architectures when using gcc.
374 2005-11-13 Theodore Ts'o <tytso@mit.edu>
376 * ext2fs.h: Add #include <string.h> since the inline functions use
377 memcpy(). (Addresses Sourceforge Bug #1251062)
379 2005-11-09 Theodore Ts'o <tytso@mit.edu>
381 * Fix a bug when writing an external journal device on an big
382 endian machine (such as a S/390), where when the number of
383 block groups is zero, we never end up writing out the
384 primary superblock at all.
386 2005-09-24 Theodore Ts'o <tytso@mit.edu>
388 * ext2fs.h, bb_inode.c, closefs.c, initialize.c, mkdir.c,
389 mkjournal.c, res_gdt.c: If fs->now is non-zero, use that
390 as the time instead of the system time when setting
391 various filesystem fields (last modified time, last write
394 2005-08-28 Matthias Andree <matthias.andree@gmx.de>
396 * Fix compiler warnings about missing memcpy prototypes.
398 2005-07-25 Theodore Ts'o <tytso@mit.edu>
400 * test_io.c (safe_getenv): Pass in zero to the unusued arguments
401 of prctl(PR_GET_DUMPABLE) to avoid false positives from
404 2005-07-19 Theodore Ts'o <tytso@mit.edu>
406 * mkjournal.c (ext2fs_add_journal_inode): Check for the case where
407 the filesystem is apparently not mounted, but the device
408 is still busy. This can happen when the luser doesn't
409 bother to mount /proc and has a bogus /etc/mtab, but still
410 wants to mount the filesystem before using tune2fs(?!?).
411 Add a safety check to save him from his own stupidity, at
412 least on 2.6 kernels. (Addresses Debian Bug #319002)
414 2005-07-09 Andreas Dilger <adilger@clusterfs.com>
416 * getsize.c (ext2fs_get_device_size): Use fstat/fstat64 to get
417 size of regular files. Fix file descriptor leaks in error

422 * Release of E2fsprogs 1.38
424 2005-06-30 Theodore Ts'o <tytso@mit.edu>
426 * bitops.h, bitops.c (ext2fs_set_bit, ext2fs_clear_bit,
427 ext2fs_test_bit): Change these function prototypes to be
428 unsigned int's. Negative bit numbers were never allowed
429 (and never made any sense), so this should be a safe
430 change. This is needed to allow safe use of block numbers
431 greater than or equal to 2**31.
433 2005-06-27 Stephen Tweedie <sct@redhat.com>
435 * ext2fs.h (ext2fs_resize_mem): Fix C99 strict type aliasing
436 problems. Addresses Red Hat Bugzilla #161183.
438 2005-06-19 Theodore Ts'o <tytso@mit.edu>
440 * getsectsize.c (BLKSSZGET): Clean up test for when to manually
441 define the BLKSSZGET ioctl.

445 * ismounted.c (ext2fs_check_mount_point): Add test to see if the
446 device appears to be busy; this only works on Linux 2.6+
447 systems, but provides some additional bullet-proofing in
450 2005-05-08 Theodore Ts'o <tytso@mit.edu>
452 * test_io.c (safe_getenv): Fix bug so it would fetch the right
453 environment variable.
455 2005-04-09 Theodore Ts'o <tytso@mit.edu>
457 * inode.c (ext2fs_write_new_inode),
458 ind_block.c (ext2fs_read_ind_block): Add missing return
459 value in error return case. (Otherwise we return garbage
460 instead of the error code.)
462 2005-03-31 Theodore Ts'o <tytso@mit.edu>
464 * test_io.c (test_open): If called by a setuid/setgid or an
465 otherwise privileged program, be paranoid and ignore the
466 TEST_IO_* environment variables.
468 2005-03-21 Theodore Ts'o <tytso@mit.edu>
470 * Release of E2fsprogs 1.37
472 2005-03-21 Theodore Ts'o <tytso@mit.edu>
474 * ext2_ext_attr.h (EXT2_XATTR_LEN, EXT2_XATTR_SIZE): Add new
475 convenience cpp macros.
477 2005-03-20 Theodore Ts'o <tytso@mit.edu>
479 * mkdir.c (ext2fs_mkdir): Call ext2fs_write_new_inode() instead of
480 ext2fs_write_inode().
482 * inode.c (ext2fs_write_new_inode): New function which should be
483 used when the caller is writing an inode for the first
484 time. It makes sure that the extra portion of the large
485 inode is initialized properly.
487 2005-03-18 Theodore Ts'o <tytso@mit.edu>
489 * Makefile.in: Fix clean target to remove tst_getsectsize.
491 * getsize.c (ext2fs_get_device_size): Check to see if the number
492 of blocks is greater than 2**32 when we are doing a binary
493 search to determine the device size. Thanks to Stephen
494 Tweedie for the patch.
496 2006-02-05 Theodore Ts'o <tytso@mit.edu>
498 * Release of E2fsprogs 1.36
500 2005-02-05 Theodore Ts'o <tytso@mit.edu>
502 * Makefile.in: Remove ext2fs.pc on a "make distclean"
504 2005-02-04 Theodore Ts'o <tytso@mit.edu>
506 * Makefile.in (clean): Remove tst_getsize when doing a make clean
508 2005-02-03 Theodore Ts'o <tytso@mit.edu>
510 * bitops.c: Make the generic functions more efficient.
512 * bitops.h: Drop SPARC assembly code. It's less efficient than GCC
513 3.4 compiled code and also triggers nasty compiler
514 warnings on sparc64. Thanks to Matthias Andree for his
515 analysis and suggestion.
517 2005-01-27 Theodore Ts'o <tytso@mit.edu>
519 * res_gdt.c (ext2fs_create_resize_inode): Create the resize inode
520 even if s_reserved_gdt_blocks is zero.
522 2005-01-26 Theodore Ts'o <tytso@mit.edu>

526 2005-01-25 Theodore Ts'o <tytso@mit.edu>
528 * ext2fs.h: Add definition of struct ext2_inode_large
530 * ext2_fs.h: Add new function prototypes
532 * ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr): The
533 ext2fs_swap_ext_attr() has been moved to swapfs.c, and
534 given a new argument, has_header.
536 * swapfs.c (ext2fs_swap_ext_attr): Moved from ext_attr.c, and
537 takes an argument which controls whether or not there is
538 an EA header which needs to be byteswaped.
539 (ext2fs_swap_inode_full): New function which byte-swaps
542 * inode.c (ext2fs_get_next_inode_full, ext2fs_read_inode_full,
543 ext2fs_write_inode_full): New functions, originally from
544 Alex Tomas, but which needed to be substantially fixed so
545 that the tests wouldn't cause major stack overwrite bugs
546 in byte-swapping is enabled.
548 2005-01-18 Theodore Ts'o <tytso@mit.edu>
550 * Makefile.in: Fix the kernel compile-time echo commands to be
551 consistent and portable
553 2005-01-07 Theodore Ts'o <tytso@mit.edu>
555 * unlink.c (ext2fs_unlink): If both the name and the inode number
556 are unspecified, then return an error, so that we don't do
557 something surprising such as unconditionally deleting the
558 first directory entry.
559 (unlink_proc): Delete directory entries by coalescing it
560 with the previous entry, to avoid directory fragmentation.
562 2005-01-06 Theodore Ts'o <tytso@mit.edu>
564 * version.c (ext2fs_parse_version_string): Change parsing
565 algorithm so that version strings such as 1.36-rc1 returns
566 a non-surprising result (i.e., 136, and not 1361).
568 2005-01-05 Theodore Ts'o <tytso@mit.edu>
570 * block.c (block_iterate_ind, block_iterate_dind,
571 block_iterate_tind): Move the code which byte swaps and
572 read/writes indirect blocks to ext2fs_{read,write}_ind_block.
573 This saves 400 bytes, and we need them for the
574 resize_inode handling.
576 * ind_block.c (ext2fs_read_ind_block, ext2fs_write_ind_block): New
579 * res_gdt.c (ext2fs_create_resize_inode): Use
580 ext2fs_{read,write}_ind_block so that byte swapping is
581 handled on big-endian systems.
583 * dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handle
584 has its own copy of the orig_super data structure. (This
585 is a better way of fixing a double-free problem in
586 resize2fs which Fedora attempted to fix in
587 e2fsprogs-1.35-double_free.patch. Addresses Red Hat
590 2004-12-23 Theodore Ts'o <tytso@mit.edu>
592 * inode.c (ext2fs_flush_icache): When flushing the icache, clear
593 the last-read block information as well.
595 * ext2fs.h (BMAP_SET), bmap.c (ext2fs_bmap): Add support for new
596 flag, BMAP_SET, which allows the caller to set a
597 particular logical->physical block mapping.
599 * ext2_err.et.in (EXT2_ET_SET_BMAP_NO_IND): New error code
601 * initialize.c (calc_reserved_gdt_blocks): #ifdef out all
602 debugging printf statements.

605 EXT2_ET_RESIZE_INODE_CORRUPT if the resize inode is not
606 what we expect. #ifdef out all debugging printf
609 * ext2_err.et.in (EXT2_ET_RESIZE_INODE_CORRUPT): Add new error code.
611 2004-12-22 Theodore Ts'o <tytso@mit.edu>

619 res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
620 ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
621 ext2fs_bg_has_super() back to closefs.c. There's no
622 reason for the new file, since list_backups() isn't being
623 used by any other functions, and can be made static, and
624 all users of the ext2fs filesystem will have to call
625 ext2fs_close() anyway.
627 2004-12-15 Theodore Ts'o <tytso@mit.edu>
629 * Applied resize inode patch from Andreas Dilger
631 * res_gdt.c (ext2fs_create_resize_inode): New function that
632 creates the resize inode.
634 * initialize.c (ext2fs_initialize): Reserve space for the resize
637 * ext2fs.h (EXT2_LIB_FEATURE_COMPAT_SUPP): Add
638 EXT2_FEATURE_COMPAT_RESIZE_INODE to the list of supported
640 Add function prototypes for res_gdt.c and sparse.c.
642 * closefs.c (ext2fs_super_and_bgd_loc): Take the reserved blocks
643 into account when calculating the number of overhead
646 * closefs.c (ext2fs_bg_has_super, test_root), sparse.c: Move these
647 functions to the new file sparse.c
649 * alloc_sb.c (ext2fs_reserve_super_and_bgd): Reserve the blocks
650 saved in the resize inode as being in use.
652 * ext2_err.et.in (EXT2_ET_RES_GDT_BLOCKS): Add new error code.
654 * Makefile.in (srcdir): Add res_gdt.c and sparse.c to the ext2fs

669 * test_io.c (test_set_option): Add support for the set_option method.
671 * ext2_io.h: Add new io_channel method, set_option(), and change
672 io_channel_write_byte() from a macro to a library function.
674 * ext2fs.h, openfs.c(ext2fs_open2): New version of ext2fs_open
675 which adds a new parameter, io_options.
676 (ext2fs_open): If there is a question mark in the
677 filename, and no io_options are specified, assumed that
678 the text following the question mark are io_options.
680 * io_manager.c, Makefile.in: New source file which contains
681 high-level functions for the io_channel layer.
683 * freefs.c (ext2fs_free): Make sure we don't free the io_channel
686 * Makefile.in: Use Linux-kernel-style makefile output to make it
687 easier to see errors/warnings.
689 2004-11-29 Theodore Ts'o <tytso@mit.edu>
691 * ext2_fs.h (EXT2_EXTENTS_FL, EXT3_FEATURE_INCOMPAT_EXTENTS,
692 EXT2_MAX_BLOCK_LOG_SIZE): Add definition for extent
693 feature and inode flag. Change maximum allowable block
696 2004-10-08 Theodore Ts'o <tytso@mit.edu>
698 * getsize.c (ext2fs_get_device_size): Add support for Windows
699 9x/NT under Cygwin. Thanks to Sam Robb
700 (samrobb@users.sourceforge.net) for pointing this and the
701 suggested code patch.

705 * getsize.c: Clean up header #include's.
707 * llseek.c (ext2fs_llseek): On non-linux systems, use lseek64() if

712 * rw_bitmaps.c (read_bitmaps), block.c (block_iterate_ind,
713 block_iterate_dind, block_iterate_tind), inode.c
714 (ext2fs_read_inode): If EXT2_FLAG_IMAGE_FILE is set, so
715 read the metadata from fs->image_io instead of fs->io.
717 * initialize.c (ext2fs_initialize), openfs.c (ext2fs_open):
718 Initialize fs->image_io to be the same as fs->io.
720 * ext2_err.et.in (EXT2_ET_NOT_IMAGE_FILE): Add new error code.
722 * openfs.c (ext2fs_get_data_io, ext2fs_set_data_io,
723 ext2fs_rewrite_to_io): New functions that allow
724 applications to manipulate fs->image_io and fs->io safely.
726 * freefs.c (ext2fs_free): If fs->image_io is different fs->io,
727 then call io_channel_close on fs->image_io.
729 * ext2fs.h: Add image_io element to the ext2_filsys data
730 structure. Add ext2fs_get_data_io() ext2fs_set_data_io(),
731 and ext2fs_rewrite_to_io() prototypes.

735 * closefs.c (ext2fs_flush): Make sure the master superblock is
736 written last, and only after other I/O has been flushed to
737 disk. Thanks to Junfeng Yang from the Stanford
738 Metacompilation group for pointing a potential ordering
739 constraint problem if we don't write things out in the
742 * test_io.c: Implement the ability to abort after n reads or
743 writes to a particular block. The block is specified by
744 TEST_IO_BLOCK environment variable, and the read/write
745 count by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT
746 environment variables. The block data is now only dumped
747 if the 0x10 bit is set in TEST_IO_FLAGS.
749 2004-04-03 Theodore Ts'o <tytso@mit.edu>
751 * ext2_types.h.in: Remove check for _UUID_TYPES since uuid_types.h
754 2004-03-08 Theodore Ts'o <tytso@mit.edu>
756 * getsize.c (ext2fs_get_device_size): Only use the BLKGETSIZE64
757 ioctl on Linux 2.6 since it is unreliable in Linux 2.4.
758 (Addresses Debian Bug #236528). Fix typo in the ioctl
761 2004-03-02 Theodore Ts'o <tytso@mit.edu>
763 * getsize.c (ext2fs_get_device_size): Update getsize functions to
764 use Apple Darwin and Linux 64-bit ioctl's
766 2004-02-29 Brian Bergstrand <brian@bergstrand.org>
768 * Makefile.in: Use $(BSDLIB_PIC_FLAG) to determine whether to use
771 2004-02-28 Theodore Ts'o <tytso@mit.edu>
773 * Release of E2fsprogs 1.35
775 2004-02-21 Theodore Ts'o <tytso@mit.edu>

789 which we're using due to a typo in the e2fsck code. (Oops)
791 * swapfs.c (ext2fs_swap_inode): Fix byte swap bug which causes SE
792 Linux created symlinks with mandatory attributes to fail
793 to be properly handled on big endian systems. (Addresses
795 (ext2fs_swap_super): Byte swap some new fields in the
796 superblock, including the journal backup fields.
798 2003-12-02 Theodore Ts'o <tytso@mit.edu>
800 * alloc.c, bb_inode.c, bitops.c, block.c, check_desc.c, closefs.c,

814 out where to write the superblock and block group
817 * alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
818 reserves space in the block bitmap using
819 ext2fs_super_and_bgd_loc.
821 * initialize.c (ext2fs_initialize): Use
822 ext2fs_reserve_super_and_bgd to initialize the block bitmap.
824 2003-08-20 Theodore Ts'o <tytso@mit.edu>
826 * inode_io.c (ext2fs_inode_io_intern2), ext2fs.h: Add new function
827 allows the caller to pass in the inode data structure.
829 * fileio.c (ext2fs_file_open2), ext2fs.h: Add new function which
830 allows the caller to pass in the inode to be used in the
833 * ext2_fs.h: Add a backup of the location of the journal inode
834 blocks to the superblock.
836 * mkjournal.c (write_journal_inode): Save the location of the
837 journal inode to the backup location in the superblock.
839 2003-08-01 Philipp Thomas <pthomas@suse.de>

846 mkjournal.c, namei.c, newdir.c, openfs.c, rs_bitmap.c,
847 rw_bitmaps.c, test_io.c, unix_io.c: ext2fs_getmem(),
848 ext2fs_free_mem(), and ext2fs_resize_mem() all now take a
849 'void *' instead of a 'void **' in order to avoid pointer
850 aliasing problems with GCC 3.x.
852 2003-07-25 Theodore Ts'o <tytso@mit.edu>
854 * Release of E2fsprogs 1.34
856 2003-07-06 Theodore Ts'o <tytso@mit.edu>
858 * kernel-jbd.h, flushb.c: Fix gcc -Wall nitpicks (indented cpp
861 * ext2_types.h.in, initialize.c: Fix gcc -Wall nitpicks
864 * ismounted.c: Fix gcc -Wall nitpicks (Don't use exit as a goto label)
866 * llseek.c: Fix gcc -Wall nitpicks (don't use #elsif)
868 * lookup.c, read_bb.c: Fix gcc -Wall nitpicks (indent
869 non-traditional #pragma)
871 * test_io.c: Fix gcc -Wall nitpicks (const/unsigned type issues)
873 2003-06-24 <tytso@snap.thunk.org>
875 * badblocks.c, ext2fs.h (ext2fs_u32_list_find,

889 caching by the unix_io layer. Not enabled, only for
892 2003-05-05 Theodore Ts'o <tytso@mit.edu>
894 * test_io.c: Pay attention to the environment variables
895 TEST_IO_LOGFILE, TEST_IO_FLAGS, and TEST_IO_BLOCK to
896 determine whether or not we should log io activity, and to
899 2003-05-03 Theodore Ts'o <tytso@mit.edu>
901 * tst_badblocks.c (file_test): Use tmpfile() instead of mktemp().
903 2003-04-29 Theodore Ts'o <tytso@mit.edu>
905 * getsize.c (ext2fs_get_device_size): Allow windows code to get
906 the resize for filesystems that are in regular files.
908 2003-04-21 Theodore Ts'o <tytso@mit.edu>
910 * Release of E2fsprogs 1.33
912 2003-04-21 Theodore Ts'o <tytso@mit.edu>
914 * Makefile.in: Use DYLD_LIBRAY_PATH so that "make check" works on
915 Darwin systems when building with shared libraries.
917 2003-04-18 Theodore Ts'o <tytso@mit.edu>
919 * unix_io.c: Use __CYGWIN__ instead of CYGWIN.
921 2003-04-17 Theodore Ts'o <tytso@mit.edu>

935 2003-04-11 Theodore Ts'o <tytso@mit.edu>
937 * ext2_fs.h (EXT2_FEATURE_RO_COMPAT_BTREE_DIR): Comment out unused
940 2003-03-30 Theodore Ts'o <tytso@mit.edu>
942 * Makefile.in: Use the compile_et --build-tree option.

954 * fileio.c (ext2fs_file_lseek): Fix bug added when adding 64-bit
955 support; avoid null dereference when ret_pos is NULL.
957 2003-03-06 Theodore Tso <tytso@mit.edu>
959 * ext2_types.h.in: Don't redefine types if other e2fsprogs
960 *_types.h files have been included already.
962 * kernel-jbd.h: Use C99 variadic cpp macros if not using GCC.
963 (Older GCC's don't support the C99 variadic macros.)
965 * flushb.c (ext2fs_sync_device),
966 ismounted.c (ext2fs_check_mount_point): Avoid GCC extension:
967 #warning not supported by Solaris suncc
969 * ext2_ext_attr.h: Avoid GCC extension: 0 length arrays in

983 * fileio.c (ext2fs_file_read, ext2_file_lseek,
984 ext2_file_get_size): Add 64-bit support.
986 * ext2fs.h (EXT2_I_SIZE): Add macro which caluates a 64bit size
987 from i_size and i_size_high.
989 2003-01-19 Theodore Ts'o <tytso@mit.edu>
991 * initialize.c (ext2fs_initialize): If the user specifies a really
992 large number of inodes, then reduce the number of blocks
993 per group until we find a workable set of filesystem
996 * ext2_err.et.in (EXT2_ET_TOO_MANY_INODES): Add new error code.
998 2002-11-09 Theodore Ts'o <tytso@mit.edu>
1000 * Release of E2fsprogs 1.32
1002 2002-11-09 Theodore Ts'o <tytso@mit.edu>
1004 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
1005 unix_write_blk): Optimize routines so that we don't end up
1006 searching the cache twice when a block isn't in the
1007 cache. If reads are larger than READ_DIRECT_SIZE, don't
1008 let them go through the cache.
1010 * unix_io.c (find_cached_block): Fixed bug which caused some clean
1011 blocks to be erroneously marked as dirty, so they would
1012 get written back to the disk before they are evicted from
1013 the cache. Harmless, but it slows down e2fsck
1016 2002-11-08 Theodore Ts'o <tytso@mit.edu>
1018 * Release of E2fsprogs 1.31
1020 2002-11-08 <tytso@snap.thunk.org>
1022 * Makefile.in (check): Skip trying to compile test_byteswap
1023 if --disable-byteswaap had been given to configure.
1025 2002-11-07 <tytso@snap.thunk.org>
1027 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
1028 support when the MASTER_SB_ONLY flag is set. Some of
1029 the descriptor blocks that should have been written out
1030 were getting skipped.
1032 2002-10-31 Theodore Ts'o <tytso@mit.edu>
1034 * Release of E2fsprogs 1.30
1036 2002-10-31 Theodore Ts'o <tytso@mit.edu>
1038 * ext2_fs.h: Add support for a new inode flag, which is to be used
1039 for indicating the top of directory hierarchies for the
1040 Orlov block allocator.
1042 * ismounted.c (check_mntent, check_mntent_file): Add better
1043 support for loopback-mounted filesystems. Check /etc/mtab
1044 if /proc/mounts doesn't turn up any mount flags, since
1045 /etc/mtab has the loopback image filename, instead of
1046 /dev/loop0. Also, check based on st_dev and st_ino, so
1047 that if a relative pathname or a pathnames using symbolic
1048 links are used, we can detect the the filesystem correctly
1049 in those cases. (Addresses Sourceforge bug #619119)
1051 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
1052 don't try the FDFLUSH ioctl that was required for floppies
1053 with older kernels. This avoids needless whining from the
1054 MD device driver. (Addresses Sourceforge bug #545832).
1056 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
1057 wrong group_block to ext2fs_descriptor_block_loc if we're
1058 using the backup superblock/block group descriptors.
1059 (ext2fs_descriptor_block_loc): If we're using the backup
1060 superblock descriptors, use the backup descriptor block in
1061 the next block group.
1063 2002-10-30 Theodore Ts'o <tytso@mit.edu>
1065 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
1066 table so that it buts up against the bitmap blocks, to
1067 avoid block fragmentation.
1069 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
1070 bug; only allocate group descriptor blocks up to
1073 2002-10-25 Theodore Ts'o <tytso@mit.edu>
1075 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
1076 know when a filesystem was created. (Sometimes this can
1079 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
1081 2002-10-20 Theodore Ts'o <tytso@valinux.com>
1083 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
1084 the journal data mode.
1086 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
1087 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
1088 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
1089 the meta_blockgroup filesystem format.
1091 2002-10-15 <tytso@snap.thunk.org>
1093 * ext2_fs.h: Add new field in superblock for default mount options.
1095 2002-10-13 Theodore Ts'o <tytso@mit.edu>
1097 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
1100 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
1102 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1103 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
1104 because the bitmap is getting written to disk. Make
1105 ext2fs_swap_bitmap be a static function, since it's not
1106 intended to be exported.
1108 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
1110 2001-09-24 Theodore Tso <tytso@mit.edu>
1112 * Release of E2fsprogs 1.29
1114 2001-08-31 Theodore Tso <tytso@thunk.org>
1116 * Release of E2fsprogs 1.28
1118 2002-08-31 Theodore Ts'o <tytso@valinux.com>
1120 * dblist.c (ext2fs_dblist_sort): New function which allows the
1121 caller to pass in a special sort comparison function.
1123 2002-08-20 Theodore Ts'o <tytso@mit.edu>
1125 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
1126 failed to accurately characterize non-standard slow
1127 symlinks. (Which don't appear in practice on real-life
1128 systems, fortunately.)
1130 2002-08-17 Theodore Ts'o <tytso@mit.edu>
1132 * Makefile.in: Remove inode_io.o from the standard object files,
1133 and only build it if debugfs is enabled (it requires
1134 fileio.o, which is only built if --disable-debugfs isn't
1135 specified to configure).
1137 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
1138 incompatible way so that it is no longer
1139 endian-dependent. Add the TEA hash. Allow the seed
1140 parameter to be optional.
1142 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
1143 These features are all now in the HALF_MD4 hash. Add
1144 definition for EXT2_HASH_TEA.
1146 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
1147 a pointer instead of an array.
1149 2002-08-16 Theodore Ts'o <tytso@mit.edu>
1151 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
1153 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
1154 the number of data blocks used by an inode exclusive of
1157 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
1158 adjusts the reference count in an extended attribute block.
1160 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
1161 correctly deal with extended attribute blocks in symbolic
1164 2002-08-13 <tytso@snap.thunk.org>
1166 * Makefile.in: Move dupfs.o and test_io.o from the
1167 needed-by-debugfs object list to the needed-by-resizer
1168 object list. Fixes compile problem if the system is built
1169 with only --disable-debugfs.
1171 2002-07-29 Theodore Ts'o <tytso@mit.edu>
1173 * link.c (ext2fs_link): When adding a new link to a directory,
1174 clear the HTREE bit.
1176 2002-07-23 Theodore Ts'o <tytso@mit.edu>
1178 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
1179 calculations for names > 32 characters to be completely
1180 bogus. Changed MD4 calculation to match what is currently
1181 being used in the CVS gkernel tree.
1183 2002-07-19 Theodore Ts'o <tytso@mit.edu>
1185 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
1186 superblock definition.
1188 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
1189 create a set of u32_list functions.
1191 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
1192 since that's required by the directory indexing code.
1194 2002-07-14 Theodore Ts'o <tytso@mit.edu>
1196 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
1197 using a C++ reserved word.
1199 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
1200 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
1201 old version of glibc (built against 2.2 headers) will
1202 interact badly with the workaround to actually cause more
1203 problems. I hate it when the glibc folks think they're
1204 being smarter than the kernel....
1206 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
1208 * ext2_fs.h: Add superblock field for reserved group descriptors.
1210 2002-06-28 Theodore Ts'o <tytso@mit.edu>
1212 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
1213 ext2fs_cpu_to_{l,b}e{32,16}
1215 2002-06-27 Theodore Ts'o <tytso@mit.edu>
1217 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
1218 Add appropriate fallbacks in this case.
1220 2002-06-26 Theodore Ts'o <tytso@mit.edu>
1222 * dirhash.c (ext2fs_dirhash): Change function signature to support
1223 a hash seed, and to return the minor hash (for 64-bit hash
1224 support). Add support for the half MD4, half MD4 with
1225 seed, and half MD4 with seed and 64 bits.
1227 2002-06-15 Theodore Ts'o <tytso@mit.edu>
1229 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
1231 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
1233 * ext2_fs.h: Add macros for maximum block/inode counts:
1234 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
1235 and EXT2_MAX_INODES_PER_GROUP.
1237 * openfs.c (ext2fs_open): Check that the number of blocks in a group
1238 is less than 2^16, otherwise we need an INCOMPAT flag (not
1239 in existence yet, if ever) to open such a filesystem.
1241 * initialize.c (ext2fs_initialize): Limit the number of blocks and
1242 inodes in a group to less than 2^16.
1244 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
1246 * ext2_fs.h: Further minor cleanups of the header. Consolidate
1247 some checks for __KERNEL__ into one place.
1249 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
1251 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
1252 the EXT2_SB() macro instead. Remove kernel function
1253 prototypes also. This matches the 2.5 kernel, and
1254 is also cleaner for other reasons. Whitespace cleanup.
1256 2002-05-21 Theodore Ts'o <tytso@mit.edu>
1258 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
1260 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
1262 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
1264 * initialize.c (ext2fs_initialize): Remove assumption that
1265 blocksizes are always <= 4k.
1267 2002-05-11 Theodore Ts'o <tytso@mit.edu>
1269 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
1270 silently if inode pointer is NULL (and ext2fs_bmap is
1271 expected to read the inode itself).
1273 2002-04-27 Theodore Ts'o <tytso@mit.edu>
1275 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
1276 file we are checking is a block device file before looking
1277 at st_rdev, since it's not valid for normal files.
1278 (is_swap_device): Move so that it is outside the
1279 HAVE_MNTENT_H, so that it is always built.
1281 2002-03-11 Theodore Tso <tytso@mit.edu>
1283 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
1284 functions which take an extra flags argument. The flag
1285 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
1286 field is byte swampped on big-endian machines, since in
1287 the V2 structure, name_len is a char field which is
1288 doesn't need to be byte swapped --- except if an
1289 old-style kernel had byte-swapped the name_len field
1290 as part of the V1 structure.
1292 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
1294 * dirhash.c (ext2fs_dirhash): New function which calculates the
1295 hash for a filename in an indexed directory.
1297 2002-03-08 Theodore Tso <tytso@mit.edu>
1299 * Release of E2fsprogs 1.27
1301 2002-03-07 Theodore Tso <tytso@mit.edu>
1303 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
1305 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
1306 tst_byteswap.c: Fix gcc -Wall complaints
1308 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
1309 (From Philipp Thomas <pthomas@suse.de>)
1311 2002-02-25 Theodore Tso <tytso@mit.edu>
1313 * ext2_fs.h: Add structure definitions for the directory indexing
1316 2002-02-23 Theodore Tso <tytso@mit.edu>
1318 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
1319 it doesn't break things on mis32, sparc32, and alpha
1322 2002-02-21 Theodore Tso <tytso@mit.edu>
1324 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
1325 we were missing an fclose().
1327 2002-02-20 Theodore Tso <tytso@mit.edu>
1329 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
1330 abstraction interface which exports an ext2 inode.
1332 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
1333 as a public interface. Change void * to const void * in
1334 ext2fs_file_write's interface.
1336 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
1337 conditional; save a few bytes.
1339 2002-02-12 Theodore Tso <tytso@mit.edu>
1341 * Makefile.in (tst_badblocks): Add some extra .o files when
1342 linking the debugging program tst_badblocks which are
1343 needed if we aren't compiling with inline functions enable.
1345 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
1346 define away __inline__ since it may not be supported.
1348 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
1349 stripped down jbd_debug that doesn't use variadic
1350 arguments. This will cause warnings under AIX, but things
1353 2002-02-03 Theodore Tso <tytso@thunk.org>
1355 * Release of E2fsprogs 1.26
1357 2002-02-03 Theodore Tso <tytso@mit.edu>
1359 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
1360 so that the number of directories in use is adjusted
1363 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
1364 which optionally will modify the number of directories
1367 2002-01-03 Theodore Tso <tytso@mit.edu>
1369 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
1370 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
1371 which will return deleted directory entries.
1372 ext2fs_dir_iterate2 takes a new callback function which
1373 is identical with the one used by
1374 ext2fs_dblist_dir_iterate(). If the directory entry is
1375 deleted, the callback function will be called with the
1376 entry paraemter set to DIRENT_DELETED_FILE.
1378 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
1379 ext2fs_block_alloc_stats): New functions which update
1380 block/inode allocation statistics in the bitmaps, block
1381 group descriptors, and superblock.
1383 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
1384 expanddir.c (expand_dir_proc), bb_inode.c
1385 (clear_bad_block_proc, set_bad_block_proc,
1386 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
1387 Update to use new block/inode allocation statistics.
1389 2001-12-24 Theodore Tso <tytso@mit.edu>
1391 * ismounted.c (is_swap_device): New function used by
1392 ext2fs_check_if_mounted and ext2fs_check_mount_point which
1393 determines whether or not the specified device is a swap
1394 device by using /proc/swaps. More bulletproofing for
1395 idiotic/careless system administrators!
1397 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
1398 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
1399 field to struct_ext2_filsys, umask. This field is
1400 initialize to 022, and affects ext2fs_mkdir in the obvious
1401 way. (In the future umask should also affect new file
1402 creation routines, but the fileio functions don't
1403 currently support this yes.)
1405 * ismounted.c (check_mntent_file): Stat all of the entries in
1406 /etc/mtab and/or /proc/mounts in order to catch dim-witted
1407 system administrators who might have created alias
1410 2001-12-23 Theodore Tso <tytso@mit.edu>
1412 * Makefile.in, jfs_user.h: Move linux/jbd.h to
1413 ext2fs/kernel-jbd.h, to avoid using the system header
1414 file version of hbd.h when using diet glibc (since it
1415 forcibly adds /usr/include to the beginning of the
1416 include search path.)
1418 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
1419 include/linux directory.
1421 2001-12-16 Theodore Tso <tytso@mit.edu>
1423 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
1424 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
1425 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
1427 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
1430 2001-12-03 Theodore Tso <tytso@mit.edu>
1432 * unix_io.c (unix_open): Make sure the ulimit workaround works
1433 regardless of the version of glibc which is used to
1436 2001-11-26 Theodore Tso <tytso@mit.edu>
1438 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
1439 trying to unset the filesize limit if at all possible,
1440 if a block device is getting opened. (The filesize limit
1441 shouldn't be applied against writes to a block device, but
1442 starting in 2.4.10, the kernel is doing this.)
1444 2001-11-05 Theodore Tso <tytso@mit.edu>
1446 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
1447 file on adding a journal to an already-mounted filesystem,
1448 try to clear the ext2 file attributes on an already
1449 existing .journal file so that we don't fail if on a
1450 partially added journal to the filesystem.
1452 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
1453 which signals that a particular inode should not have the
1454 last bits of data (the "tail") be merged with another
1455 file. This is necessary to keep LILO happy.
1457 2001-09-20 Theodore Tso <tytso@thunk.org>
1459 * Release of E2fsprogs 1.25
1461 2001-09-16 Theodore Tso <tytso@mit.edu>
1463 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
1464 which was breaking the build on the Hurd. (Addresses
1465 Debian bug #112414).
1467 2001-09-13 Theodore Ts'o <tytso@mit.edu>
1469 * ismounted.c (check_mntent_file): We now validate the entry in
1470 /etc/mtab to make sure the filesystem is really mounted,
1471 since some broken distributions (read: Slackware) have
1472 buggy boot scripts that don't initialize /etc/mtab before
1473 checking non-root filesystems. (Slackware also doesn't
1474 check the root filesystem separately, and reboot if the
1475 root filesystem had changes applied to it, which is
1476 dangerous and broken.)
1478 2001-09-02 Theodore Tso <tytso@thunk.org>
1480 * Release of E2fsprogs 1.24a
1482 2001-08-30 Theodore Tso <tytso@thunk.org>
1484 * Release of E2fsprogs 1.24
1486 2001-08-30 Theodore Tso <tytso@valinux.com>
1488 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
1489 changes, since the ioctl number has been reused by another
1492 2001-08-15 Theodore Tso <tytso@valinux.com>
1494 * Release of E2fsprogs 1.23
1496 2001-08-05 Theodore Tso <tytso@valinux.com>
1498 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
1499 version of the bitmap test routines to speed up these
1500 routines. (At some point I may want to make these
1501 routines use the find_first_bit functions, but that will
1502 add a lot of complexity since it means that these
1503 functions will have to break the bitmap abstraction
1504 boundary. It's not clear it's worth it.)
1506 * mkjournal.c (mkjournal_proc): Remember the last block allocated
1507 to speed up ext2fs_new_block().
1509 2001-07-29 Theodore Tso <tytso@valinux.com>
1511 * finddev.c (scan_dir): Fix memory leak; we weren't calling
1512 closedir() when exiting the function in all cases.
1514 2001-07-27 Theodore Tso <tytso@valinux.com>
1516 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
1517 block usable in the journal for external journals to be 2
1518 or 3, depending on the blocksize, so that the existing
1519 kernel code does the right thing.
1521 * getsize.c (ext2fs_get_device_size): Add support for the
1522 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
1523 from Ben LaHaise, but it's likely this interface won't
1526 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1527 when writing the journal superblock, too. (Oops! Needed
1528 to make 1k filesystems with external journal to work.)
1530 2001-07-26 Theodore Tso <tytso@valinux.com>
1532 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1533 to find the journal superblock if the blocksize is 1024.
1535 2001-07-21 Theodore Tso <tytso@valinux.com>
1537 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
1539 2001-07-20 Theodore Tso <tytso@valinux.com>
1541 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
1542 attribute block, set the filesystem changed bit.
1544 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1545 Comment out these functions since we're not using them.
1547 2001-07-10 Theodore Tso <tytso@valinux.com>
1549 * closefs.c (write_primary_superblock): After writing changes to
1550 the primary superblock, update the original superblock
1551 copy so we don't have to re-write those changes in the
1553 (ext2fs_flush): Clear the superblock dirty flag after
1554 we've flushed out changes to disk.
1556 2001-07-07 Theodore Tso <tytso@valinux.com>
1558 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
1559 to avoid register conflicts when compiling in PIC mode.
1561 2001-07-04 Theodore Tso <tytso@valinux.com>
1563 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1564 Add new functions (C and in i386 assembler) which quickly
1565 find bits set in a bitmask.
1567 2001-06-23 Theodore Tso <tytso@valinux.com>
1569 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
1570 ext2_ext_attr.h and ext_attr.c for extended attributes
1573 * Release of E2fsprogs 1.22
1575 2001-06-22 Theodore Tso <tytso@valinux.com>
1577 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
1578 descriptor so that adding a journal to a mounted
1579 filesystem doesn't die. (Fixes a bug accidentally
1580 introduced in e2fsprogs 1.21.)
1582 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
1583 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
1584 fchflags without defining UF_NODUMP. (Addresses Debian
1587 * flushb.c: Use platform independent method of defining the
1588 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
1589 since on newer glibc's BLKFLSBUF is defined there.
1591 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
1592 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
1593 to support byte swapping even if we don't support the
1594 conversion functions. (Fixes Debian bug #101686).
1596 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
1597 since the byte-swapping code all assumes the
1598 ext2_dir_entry structure. (It's a question of whether or
1599 not name_len should be byte-swapped or not, and whether
1600 it's a 16 bit or 8 bit field.)
1602 2001-06-15 Theodore Tso <tytso@valinux.com>
1604 * Release of E2fsprogs 1.21
1606 2001-06-15 Theodore Tso <tytso@valinux.com>
1608 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
1609 file which is generated and is therefore found in the
1610 build directory, not source directory.
1612 * ismounted.c (check_mntent_file): Use a test file in / to check
1613 to see if the root filesystem is mounted read-only. This
1614 protects against the case where /etc might not be on /, as
1615 well as the case where /etc/mtab doesn't exist. (Both are
1616 should-never happen scenarios, but you never know...)
1618 2001-06-14 Theodore Tso <tytso@valinux.com>
1620 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
1621 Remove unneeded #pragma argsused, since the arguments are
1624 2001-06-13 Theodore Tso <tytso@valinux.com>
1626 * ext2_types.h.in: If linux/types.h has been defined, then don't
1627 try to redefine the typedefs.
1629 * Makefile.in (HFILES): Add ext2_types.h to the list of files
1630 which should be installed.
1632 * ismounted.c (check_mntent_file): Work around GNU hurd brain
1633 damage. Addresses Debian bug #100304.
1635 * Makefile.in: Limit some .o files from being included into the
1636 library if --disable-debugfs, --disable-swapfs,
1637 --disable-imager, or --disable-resizer are used.
1639 2001-06-12 Theodore Tso <tytso@valinux.com>
1641 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
1642 function, and use the ext2fs_badblocks_* functions
1645 2001-06-11 Theodore Tso <tytso@valinux.com>
1647 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
1648 ext2fs_mark_generic_bitmap and
1649 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
1650 functions. (This saves space and doesn't significantly
1651 change the speed of e2fsck on a P-III.)
1653 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
1654 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
1655 include the byte-swapping logic if ENABLE_SWAPFS is turned
1656 on or if we're on a big-endian machine.
1658 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
1659 set EXT2_FLAG_SWAP_BYTES, instead of using
1662 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
1663 autoconf to determine whether or not return
1664 EXT2_FLAG_SWAP_BYTES.
1666 2001-06-10 Theodore Tso <tytso@valinux.com>
1668 * Makefile.in: Remove the dependence on the libe2p library.
1670 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
1671 with direct usage of the ioctl/fchflags so that we don't
1672 have to depend on the libe2p library.
1674 2001-06-08 Theodore Tso <tytso@valinux.com>
1676 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
1677 when trying to find a 32-bit wide type.
1679 * icount.c (insert_icount_el): Fix the code used to estimate the
1680 size of the new icount array to be more intelligent, to
1681 avoid reallocating the array too many times. Thanks to
1682 Enrique Perez-Terron for pointing this out.
1684 2001-06-02 Theodore Tso <tytso@valinux.com>
1686 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
1687 for a symlink to determine whether it is a fast symlink.
1689 2001-06-01 Theodore Tso <tytso@valinux.com>
1691 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
1692 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
1694 2001-05-25 Theodore Tso <tytso@valinux.com>
1696 * Release of E2fsprogs 1.20
1698 2001-05-25 Theodore Tso <tytso@valinux.com>
1700 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
1701 some to clean up Andreas's patches. Use strncpy instead
1702 of strcpy to save the root's mountpoint. Clean up #ifdef
1703 structure. Remove uneeded variable in testing/debug driver.
1705 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
1707 * ismounted.c: Add check for root device which doesn't depend on
1708 /etc/fstab or /proc/mounts to be correct. Don't call
1709 endmntent() before we are done with mnt struct.
1711 2001-05-23 Theodore Tso <tytso@valinux.com>
1713 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
1716 2001-05-21 Theodore Tso <tytso@valinux.com>
1718 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
1719 make room for pre-existing usage of
1720 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
1721 the same codepoint as EXT2_BTREE_FL.
1723 2001-05-20 Theodore Tso <tytso@valinux.com>
1725 * ext2fs.h: #include <> instead of "" for ext2fs and et header
1726 files, since they will be installed in /usr/include
1728 2001-05-14 Theodore Tso <tytso@valinux.com>
1730 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
1731 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1732 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

1741 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
1742 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
1743 Adjust all files in this directroy to include this file.
1745 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
1748 2001-05-05 Theodore Tso <tytso@valinux.com>
1750 * fileio.c (ext2fs_file_read): Factored out common code and
1751 cleaned up function. Fixed a bug where if there was an
1752 error reading from the disk, the number of bytes read
1753 wasn't reliably set. (Fixes Debian bug #79163)
1754 (ext2fs_file_write): Factored out common code and made
1755 function more efficient; if writing a full block, don't
1756 bother to do a read-modify-write cycle.
1758 2001-05-04 Theodore Tso <tytso@valinux.com>
1760 * dirblock.c (ext2fs_read_dir_block): Check for an directory
1761 record length which isn't a multiple four, and treat that
1762 as an invalid. Scan the directory and return an error
1763 (EXT2_ET_DIR_CORRUPTED) if the directory records are
1765 (ext2fs_write_dir_block): If while byte-swapping the
1766 directory block, if there's an error, abort and return
1767 EXT2_ET_DIR_CORRUPTED.
1769 2001-05-02 Theodore Tso <tytso@valinux.com>
1771 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
1772 image_header field in the ext2_filsys structure
1774 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
1775 * inode.c (ext2fs_read_inode):
1776 * rw_bitmaps.c (read_bitmaps):
1777 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
1779 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
1780 sure the full bitmap is saved.
1782 2001-05-01 Theodore Tso <tytso@valinux.com>
1784 * e2image.h (struct ext2_image_hdr): Add space for the device name
1785 in the image header.
1787 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
1788 make sure the rec_len is a multiple of 4, to prevent
1789 bus-errors on architectures which care about mis-aligned
1792 2001-04-25 Theodore Tso <tytso@valinux.com>
1794 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
1795 query the device sizes using the BLKGETSIZE ioctl.
1797 2001-04-16 Theodore Tso <tytso@valinux.com>
1799 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
1800 before checking /etc/mtab. The EXT2_MF_READONLY flag is
1801 now set from the /etc/mtab options field for all
1802 filesystems, not just the root filesystem. Add debugging
1803 code to make it easier to test ext2fs_check_if_mounted().
1805 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
1806 check; return an error if there's an attempt to create a
1807 journal less than 1024 filesystem blocks.
1809 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
1810 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
1812 2001-02-20 Theodore Tso <tytso@valinux.com>
1814 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
1817 * tst_byteswap.c: New function to test the byteswap functions.
1818 Add to regression test suite.
1820 2001-02-08 Theodore Tso <tytso@valinux.com>
1822 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
1824 2001-02-07 Theodore Tso <tytso@valinux.com>
1826 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
1827 of s_first for external devices to always be 1, since
1828 jsb->s_first is always relative to the start of the
1829 journal superblock. Use htonl(1) when setting s_nr_users.
1831 2001-01-17 Theodore Ts'o <tytso@valinux.com>
1833 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
1834 device number of the filesystem (instead of the journal)
1835 was being dropped into s_journal_dev.
1837 2001-01-15 Theodore Ts'o <tytso@valinux.com>
1839 * initialize.c (ext2fs_initialize): Add support for initializing
1840 the ext2 superblock for external journal devices. This
1841 basically means we don't bother to allocate any block
1844 * openfs.c (ext2fs_open): Only open external journal devices if
1845 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
1846 ext2fs_open. When opening such devices, don't try to read
1847 the block group descriptors, since they're not there.
1849 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
1851 * mkjournal.c: Export a new function,
1852 ext2fs_create_journal_superblock(), which allocates and
1853 returns a buffer containing a journal superblock. This is
1854 needed by mke2fs to create an external journal. Rewrote
1855 ext2fs_add_journal_device() so that it no longer creates
1856 the external journal, but rather adds a filesystem to an
1857 existing external journal. It handles all of the UUID
1860 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
1861 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
1862 Changed function prototype for ext2fs_add_journal_device().
1864 2001-01-14 Theodore Ts'o <tytso@valinux.com>
1866 * closefs.c (ext2fs_flush): Don't write out anything beyond the
1867 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
1870 2001-01-12 Theodore Ts'o <tytso@valinux.com>
1872 * imager.c: Fix gcc -Wall complaints and a series of bugs where
1873 retval wasn't set correctly. (Thanks to Andreas Dilger
1874 for pointing this out.)
1876 2001-01-11 <tytso@snap.thunk.org>
1878 * flushb.c (ext2fs_sync_device): New function which centralizes
1879 all of the places which might try to use the BLKFLSBUF
1880 or FDFLUSH ioctls (and usually failing to define them
1881 since the system header files don't usually do this for
1882 us, and we're trying to avoid usage of kernel include
1885 2001-01-10 <tytso@snap.thunk.org>
1887 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
1888 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
1889 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
1890 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
1891 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
1892 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
1893 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
1894 ext2_ino_t, to protect applications that attempt to
1895 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
1896 changes ino_t(!?). So we use ext2_ino_t to avoid an
1897 unexpected ABI change.
1899 2001-01-05 <tytso@snap.thunk.org>
1901 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
1902 we may overrun allocated memory in case of a corrupted
1903 filesystem (or an e2fsck test case :-) when byte-swapping
1904 the directory block.
1906 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
1908 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
1909 complaints including a missing return 0 at the end of
1910 ext2fs_add_journal_device.
1912 2001-01-03 <tytso@snap.thunk.org>
1914 * Makefile.in: Link in libe2p when creating libext2fs as a shared
1915 library, since mkjournal.c now references fsetflags().
1917 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
1918 Dilger's changes (with fixups) to allow on-line creation
1921 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
1922 EXT2_FLAG_SUPER_ONLY, which the close routines to only
1923 update the superblock, and not the group descriptors.
1925 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
1927 * ismounted.c: add ext2fs_check_mount_point() function, which will
1928 optionally return the mount point of a device if mounted
1930 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
1932 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
1933 ext2fs_add_journal_inode()
1935 2001-01-01 <tytso@snap.thunk.org>
1937 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
1938 source (but not binary) compatibility of some users of the
1939 ext2 library. They should just simply do a global search
1940 and replace of struct ext2fs_sb with struct
1941 ext2_super_block, and use their own private copy of
1942 ext2_fs.h if they aren't already.
1944 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
1945 Replace use of ext2fs_sb with ext2_super_block.
1947 2000-12-31 <tytso@snap.thunk.org>
1949 * ext2fs.h: Cleaned up header file by removing definitions of
1950 feature flags that might not have been defined in older
1951 ext2 header files. Now that we're using our own
1952 include/linux/ext2fs.h header file, this can never happen.
1954 * jfs_dat.h: Removed old header file which is no longer needed.
1956 2000-12-13 Theodore Ts'o <tytso@valinux.com>
1958 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
1959 by Andreas Dilger to update the filesystem revision to
1962 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
1965 2000-12-09 <tytso@snap.thunk.org>
1967 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
1968 ext2fs_add_journal_device): Add a new argument to the APIs
1969 of these function, which is a flags word. This is used to
1970 allow the creation of a V1 superblock for those folks who
1971 are using ext3 0.3b in production. Note, the user-land
1972 interface for getting at this flag won't be documented, as
1973 the V1 superblock is deprecated.
1975 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
1976 which creates a V2 superblock instead of a V1 superblock.
1978 2000-11-21 <tytso@snap.thunk.org>
1980 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
1981 out by Andreas Dilger.
1983 2000-11-05 <tytso@snap.thunk.org>
1985 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
1986 ext2_fs.h, Makefile.in: New file that has routines that
1987 save ext2fs metadata to a file.
1989 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
1991 * e2image.h: New file which defines the file format for the ext2
1992 image file. (Saved copy of ext2 metadata to a file as a
1993 saving throw against worst-case damage.)
1995 2000-11-01 <tytso@snap.thunk.org>
1997 * inode.c (ext2fs_flush_icache): Add new function
1998 ext2fs_flush_icache() which flushes the internal inode
1999 cache. Applications which modify the inode table blocks
2000 directly must call this function.
2002 2000-10-26 <tytso@snap.thunk.org>
2004 * mkjournal.c: Add #include of netinet/in.h, since Solaris
2005 requires it for ntohl().
2007 * ext2_io.h (io_channel_write_byte): Add new interface to allow
2008 callers to write specific byte ranges. This is an
2009 optional interface, which not all IO channels may
2012 * unix_io.c (unix_write_byte):
2013 * test_io.c (test_write_byte): Add implementation of the
2014 write_byte function.
2016 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
2017 function which writes the primary superblock. If the IO
2018 channel supports writing raw bytes directly, only fields
2019 which were modified are written to the disk. This makes
2020 it safe(r) to use utilities like tune2fs on a mounted
2023 * freefs.c (ext2fs_free): Free the original superblock if it is
2026 * openfs.c (ext2fs_open): Store a copy of the original superblock
2029 * ext2fs.h: Add a field to store the original superblock in the
2030 ext2 context structure.
2032 2000-10-24 <tytso@snap.thunk.org>
2034 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
2035 don't need to use llseek).
2037 2000-10-24 <tytso@valinux.com>
2039 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
2040 creating an ext3 journal on a filesystem.
2042 2000-08-21 <tytso@valinux.com>
2044 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
2046 2000-08-22 <tytso@valinux.com>
2048 * unix_io.c: Make massive changes to support a multiple block
2049 writethrough cacheing.
2051 * ext2_io.h: Added flags field to the io_channel structure.
2053 2000-08-19 <tytso@valinux.com>
2055 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
2056 provides the function ext2fs_find_block_device(). This
2057 function returns the pathname to a block device, given its
2060 2000-07-13 <tytso@valinux.com>
2062 * Release of E2fsprogs 1.19
2064 2000-07-07 Theodore Ts'o <tytso@valinux.com>
2066 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
2067 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
2068 list of filesystem flags supported by the library.
2070 2000-07-04 Theodore Ts'o <tytso@valinux.com>
2072 * ext2fs.h: Update to include latest journalling additions to the
2075 * dll/jump.funcs: Add new jumptable entries for
2076 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
2077 ext2fs_badblocks_equal.
2079 * tst_badblocks.c: Update test program to test
2080 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
2082 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
2083 writes out bad blocks list to a file.
2085 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
2086 changes the callback function to take two additional
2087 arguments; a private blind pointer supplied by the caller,
2088 and pointer to a char * containing a pointer to the
2091 * badblocks.c (ext2fs_badblocks_equal): Add new function which
2092 returns true if two badblocks list are equal.
2094 * Makefile.in: Remove explicit link of -lc in the shared library.
2095 (It shouldn't be necessary, and is harmful in some cases).
2097 2000-06-10 Theodore Ts'o <tytso@valinux.com>
2099 * getsize.c (main): Add debugging code under #ifdef DEBUG
2101 2000-05-27 Theodore Ts'o <tytso@valinux.com>
2103 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
2104 earlier, so that if there's an error reading it, we can
2105 more cleanly back out of the operation.
2107 2000-05-25 <tytso@snap.thunk.org>
2109 * getsize.c (ext2fs_get_device_size): Use open64() instead of
2110 open() if it exists. Under linux, manually define the
2111 ioctl for BLKGETSIZE if it isn't already defined and it's
2114 * unix_io.c (unix_open): Use open64() instead of open() if it
2117 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
2118 available (and prototypes are defined) use it in
2119 preference to llseek.
2121 * Makefile: Add hack dependency rule so that parallel makes work
2124 2000-05-18 Theodore Ts'o <tytso@valinux.com>
2126 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
2128 2000-04-03 Theodore Ts'o <tytso@valinux.com>
2130 * block.c: Readibility tweak in conditionals involving
2133 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
2134 how to define __s64 and __u64. Turn off "compression is
2135 experimental" warning if the cpp macro
2136 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
2138 2000-02-11 <tytso@snap.thunk.org>
2140 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
2141 Conditionally include Compression as a supported type if
2142 ENABLE_COMPRESSION (via --enable-compression) is turned on.
2144 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
2146 2000-02-08 <tytso@snap.thunk.org>
2148 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
2149 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2150 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
2151 Change to return the previous state of the bit that is
2152 being marked or unmarked. For speed optimization.
2154 2000-02-02 Theodore Ts'o <tytso@valinux.com>
2156 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
2158 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
2159 needed any more; we know it will always be i_generation.
2160 Add support for swapping the high bits of the uid and gid.
2162 1999-11-19 <tytso@valinux.com>
2164 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
2165 counts if the link was successful. Patch suggested by
2168 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
2169 the source directory.
2171 1999-11-10 <tytso@valinux.com>
2173 * Release of E2fsprogs 1.18
2175 1999-11-08 <tytso@valinux.com>
2177 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
2178 since ext2fs_badblocks_list_free was moved to freefs.c.
2180 * tst_badblocks.c: Use the newer badblocks API names. Add
2181 duplicate blocks to the test inputs to test dealing with
2182 adding blocks which are already in the badblocks list.
2184 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
2185 of the list, use a shortcut O(1) operations instead of an
2186 O(n) operation. (Idea suggested by David Beattie.)
2188 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
2189 of badblocks_list_free(), to save a procedure call.
2191 1999-10-26 <tytso@valinux.com>
2193 * Release of E2fsprogs 1.17
2195 1999-10-26 <tytso@valinux.com>
2197 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
2198 seem to handle ~0UL the same way as they used to.
2200 1999-10-25 <tytso@valinux.com>
2202 * nt_io.c (_OpenNtName): Open the device using
2203 FILE_SYNCHRONOUS_IO_NONALERT instead of

2205 (nt_open): At the end of the device open routine, unlock
2206 the drive but do not dismount it.
2208 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to

2215 1999-10-22 <tytso@valinux.com>
2217 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
2219 * link.c (ext2fs_link): This call now uses the low three bits of
2220 the flags parameter to pass the directory filetype
2221 information; it will set the directory entry FILETYPE
2222 information if the filesystem supports it.
2224 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
2225 option is set, then create the '.' and '..' entries with
2226 the filetype set to EXT2_FT_DIR.
2228 1999-09-24 <tytso@valinux.com>
2230 * nt_io.c: New file which supports I/O under Windows NT.
2232 1999-09-07 <tytso@valinux.com>
2234 * ext2fs.h: Add new fields for journalling and define new
2235 feature bits used by newer filesystems: IMAGIC_INODES,
2236 HAS_JOURNAL, RECOVER.
2238 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
2239 we update the inode block count and size files so that the
2240 block count field is updated correctly when we create an
2243 1999-07-18 Theodore Ts'o <tytso@valinux.com>
2245 * Release of E2fsprogs 1.15
2247 1999-06-23 <tytso@valinux.com>
2249 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
2250 kernels that use i_generation instead of i_version. Patch
2251 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
2253 1999-06-21 <tytso@valinux.com>
2255 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
2256 directory entry before calling the callback function.
2257 This should prevent some core dumps of insufficiently
2258 paranoid callback functions.
2260 1999-05-29 <tytso@rsts-11.mit.edu>
2262 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
2264 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
2265 that we don't handle writing yet (we do). Fixed bug where
2266 we weren't allocating a big enough buffer for ext2_bmap.
2268 1999-05-03 <tytso@rsts-11.mit.edu>
2270 * openfs.c (ext2fs_open): Check to make sure that the number of
2271 blocks per group is not zero --- if so, it must be a bad
2274 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2276 * Release of E2fsprogs 1.14
2278 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
2280 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
2281 the inode number is zero; if it's zero, return
2282 EXT2_ET_BAD_INODE_NUM.
2284 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2286 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
2287 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
2290 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
2292 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
2293 non-Linux case to use EINVAL by default, unless it isn't
2294 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
2297 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
2299 * Release of E2fsprogs 1.13
2301 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
2303 * Makefile.in: Updated dependencies.
2305 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
2307 * initialize.c (ext2fs_initialize): Make sure that we allocate
2308 enough inodes so that we can make a valid filesystem.
2310 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
2312 * rw_bitmaps.c: Fixed signed/unsigned warnings.
2314 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
2315 function declaration.
2317 * dblist.c (make_dblist): Add safety check in case the dblist
2318 pointer passed in is null (in which case, assign it to
2319 fs->dblist). Fixed some signed/unsigned warnings.
2321 * bmap.c: Make addr_per_block be of type blk_t to avoid
2322 signed/unsigned warnings.
2324 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
2325 function declaration.
2327 * get_pathname.c (get_pathname_proc): Use return value from
2328 ext2fs_get_mem, instead of checking if &gp->name is
2331 * dir_iterate.c (ext2fs_process_dir_block):
2332 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
2333 from the function declaration.
2335 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
2336 return the error directly instead of jumping to the
2337 cleanup routine, since we don't need to do any cleanup.
2339 * alloc_table.c (ext2fs_allocate_group_table): Make this
2340 function take a dgrp_t for its group argument.
2342 * ext2fs.h: Make dgrp_t an __u32 type, and make
2343 fs->desc_group_count be of type dgrp_t.
2345 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
2347 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
2348 than 10 blocks when we need to expand the size of the
2351 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2353 * Release of E2fsprogs 1.12
2355 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2357 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
2358 appropriate for all of the block group copies, so that
2359 it's clear where the beginning of the filesystem is on the
2360 disk. (For when the partition table gets scrod.)
2362 * ext2fs.h: Change the name of the feature from
2363 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
2364 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
2366 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
2368 * inode.c (get_next_blockgroup): Fix bug where if
2369 get_next_blockgroup() is called early because of a missing
2370 inode table in a block group, the current_inode counter
2371 wasn't incremented correctly.
2373 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
2375 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
2376 against a completely trashed bad block inode.
2378 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
2380 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
2381 the stride length hits a bad value, we retry the block
2382 allocation starting at the beginning of the block group.
2384 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
2385 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
2386 e2_blkcnt_t to avoid collision with LFS API.
2388 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
2390 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
2391 way that avoids overflows on disk sizes greater than 4GB.
2393 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
2395 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
2396 return type for comparison functions for qsort.
2398 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
2401 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
2403 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
2406 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
2407 evade a potential problem with glibc's header files trying
2408 to spike out linux/types.h.
2410 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
2411 include the old size of the memory, which is needed for
2412 some braindamaged memory allocation systems that don't
2415 * badblocks.c (ext2fs_badblocks_list_add):
2416 bb_inode.c (clear_bad_block_proc):
2417 dblist.c (ext2fs_add_dir_block):
2418 icount.c (insert_icount_el):
2419 irel_ma.c (ima_put):
2420 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
2421 pass the old size of the memory to be resized to
2422 ext2fs_resize_mem().
2424 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2426 * Makefile.in: Change to use new installation directory variables
2427 convention. Fix uninstall rules to take $(DESTDIR) into
2430 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
2432 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
2433 with 32 bit longs, then we need to manually define __s64
2434 and __u64, since the current kernel header files don't
2435 define these if __STRICT_ANSI__ is defined. This is a
2436 problem if we are compiling with full GCC warnings, since
2437 we do need 64 bit support.
2439 * Makefile.in (OBJS): Remove bmove.o from files to be built,
2440 since we're not using ext2fs_move_blocks() and there
2441 is some question as to its usefulness in its current
2444 * bmap.c (block_bmap): Remove unused function.
2446 * bmove.c (process_block): Fix -Wall warning.
2448 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
2450 * block.c (ext2fs_block_iterate3): Make the ref_offset field
2451 contain the offset into the inode.i_blocks array when
2452 ref_block is zero. Since we haven't done a formal
2453 release of e2fsprogs since block_iterate2 was first
2454 introduced, I removed block_iterate2, and renamed
2455 block_iterate3 to be block_iterate2.
2457 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
2458 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
2459 use of block_iterate and block_iterate2 to
2460 block_iterate2 with the new prototype for the
2461 interator function. (using blkcnt_t forr blockcount)
2463 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
2465 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
2466 s_prealloc_blocks, s_prealloc_dir_blocks). Added
2467 conditional defines of new features COMPAT_DIR_PREALLOC,
2468 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
2469 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
2470 the library to declare that we support COMPAT_DIR_PREALLOC,
2471 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
2473 * fileio.c: Rename function ext2fs_file_llseek to be
2474 ext2fs_file_lseek, which is more accurate.
2476 * block.c: Add new function ext2fs_block_iterate3 which calls
2477 the iterator function with the blockcount argument of
2478 type blkcnt_t. This version of the function is
2479 allowed to handle large files; the other fucntions are
2482 * ext2fs.h: Add new type blkcnt_t
2484 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
2486 * block.c (ext2fs_block_iterate2): Fix bug where the block count
2487 field wasn't getting correctly incremented for sparse
2488 files when the indirect or doubly-indirect block
2489 specified in the inode was zero.
2491 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2493 * unlink.c (unlink_proc):
2494 * lookup.c (lookup_proc):
2495 * link.c (link_proc):
2496 * get_pathname.c (get_pathname_proc):
2497 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
2498 from dirent->name_len, so it can be used for other
2501 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
2502 and indicate that we have support for this incompatible
2505 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2507 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
2509 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2511 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
2512 number of directories when the block group information is
2515 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
2517 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
2518 inode table is missing so that we catch the case where the
2519 first block group is missing.
2521 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
2524 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2526 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
2528 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
2530 * test_io.c (test_flush): Add a debugging printf when the flush
2533 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
2534 read in, return right away.
2536 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2538 * bitops.h: Don't try to do i386 inline asm functions if the
2541 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
2542 instead of linux/types.h, and e2_bitops.h instead of
2545 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
2548 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2550 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
2551 so that we don't need to call get_next_blockgroup() the
2552 first time around. Saves a bit of time, and prevents us
2553 from needing to assign -1 to current_group (which is an
2556 * icount.c (insert_icount_el): Cast the estimated number of inodes
2557 from a float to an ino_t.
2559 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
2560 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

2596 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2598 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
2599 paranoid about validating the directory counts from the
2600 block group information.
2602 * all files: Don't include stdlib.h anymore; include it in
2603 ext2_fs.h, since that file requires stdlib.h
2605 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2607 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
2608 bitmap is loaded, and return an error if it is not.
2609 (expand_dir_proc): Only use ext2fs_write_dir_block when

2659 physical block number.
2661 * fileio.c: New file which implements simple file reading and
2664 * alloc.c (ext2fs_alloc_block): New function which allocates a
2665 block, zeros it, and updates the filesystem accounting
2666 records appropriately.

2670 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
2671 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
2672 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
2674 * Change various library files to use these functions instead of
2675 EINVAL, ENOENT, etc.
2677 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2679 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
2680 need to declare llseek().
2682 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2684 * Rename io.h to be ext2_io.h (avoid namespace collisions)
2686 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
2688 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

2722 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2724 * io.h: Change the prototype of ext2fs_llseek() to use int's
2725 instead of unsigned int's.
2727 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
2728 to make life easer for GNU Libc 2.
2730 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
2731 filesystem has its bitmaps stored as 32-bit words with bit
2732 0 as the LSB of each word. Thus a bitmap with only bit 0
2733 set would be, as a string of bytes, 00 00 00 01 00 ... To
2734 cope with this, we byte-reverse each word of a bitmap if
2735 we have a big-endian filesystem, that is, if we are *not*
2736 byte-swapping other word-sized numbers.
2738 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

2796 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
2797 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c
2798 dirblock.c dupfs.c expanddir.c freefs.c get_pathname.c

2802 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
2803 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
2805 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2807 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
2808 is zero, then return EXT2_IO_LLSEEK_FAILED.
2810 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
2812 * Release of E2fsprogs 1.11
2814 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2816 * dblist.c (ext2fs_dblist_count): Added new function which returns
2817 the number of directory blocks in dblist.
2819 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2821 * unix_io.c (unix_flush): Make the io_channel flush function do a
2822 fsync to flush the kernel buffers to disk.
2824 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2826 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
2827 current inode number wasn't being set by the
2828 goto_blockgroup function.
2830 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2832 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
2833 of blocks which need to be moved, and moves those blocks
2834 to another location in the filesystem.
2836 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
2837 bitmap, make sure all of the new parts of the bitmap are
2840 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2842 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
2843 wasn't being returned to the caller.
2845 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
2846 ext2fs_allocate_group_table() which sets the group tables
2847 for a particular block group. The relevant code was
2848 factored out of ext2fs_allocate_tables().
2850 * dblist.c (make_dblist): Adjust the initial size of the directory
2851 block list to be a bit more realistic (ten plus twice the
2852 number of directories in the filesystem).
2854 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2856 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
2857 ext2fs_badblocks_list_test would test the list (and exceed
2858 array boundaries) if there were no bad blocks on the bad
2859 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
2861 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2863 * Release of E2fsprogs version 1.10
2865 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2867 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
2868 inode and block bitmaps based on the RAID 0 stride
2869 parameter (which is passed by mke2fs).
2871 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
2872 mke2fs to communicate the stride length to
2873 ext2fs_allocate_tables()
2875 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2877 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
2878 systems. (We can't assume that the new filesystem types
2881 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2883 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
2884 allocate the inode and block bitmaps inside block group at
2887 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2889 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
2890 filesystem has no free blocks, ext2fs_new_block would loop
2893 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
2895 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
2896 free if refcount goes to zero.
2898 * inode.c (create_icache): Initialize refcount to 1.
2900 * ext2fsP.h: Added refcount to ext2_inode_cache
2902 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
2905 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
2906 badblocks structure.
2908 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2910 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
2912 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
2914 (unix_close, test_close): Decrement the refcount and only
2915 close the io_channel if the refcount goes to 0.
2917 * io.h: Add refcount to the io_channel structure. Add new macro
2918 interface io_channel_bumpcount() to bump the refcount.
2920 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2922 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
2923 cache in the filesystem handle, instead of the inode cache
2924 in a static variable.
2926 * freefs.c: Added static function to free the inode cache (called by
2929 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
2931 * ext2fs.h: Added pointer to the inode_cache structure.
2933 * block.c (block_iterate_ind, block_iterate_dind,
2934 block_iterate_tind): If there are holes in the indirect,
2935 doubly indirect, or triply indirect blocks, increment the
2936 block count field automatically.
2938 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2940 * Release of E2fsprogs version 1.09
2942 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2944 * version.c (ext2fs_parse_version_string): Check the passed in
2945 version string (instead of the hard-coded one).
2947 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
2948 greater filesystem size, clamp it to prevent allocating a
2949 block or inode bitmap beyond the filesystem.
2951 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
2952 overhead calculation was accidentally removed.
2954 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2956 * Release of E2fsprogs version 1.08
2958 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2960 * dblist.c (ext2fs_set_dir_block): New function which sets the
2961 block of a dblist entry, given the directory inode and
2964 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2966 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
2967 inode bitmaps at staggered locations across the block
2968 groups, to avoid concentrating the bitmaps on a small
2969 number of disks when using striped RAID arrays.
2971 * initialize.c (ext2fs_initialize): By default, choose the maximum
2972 possible number of blocks per group (based on the size of
2973 the bitmaps in the blocksize).
2975 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2977 * initialize.c (ext2fs_initialize): Add support for
2978 EXT2_COMPAT_SPARSE_SUPER feature.
2980 * closefs.c (ext2fs_bg_has_super): New function to determine
2981 whether or a particular block group should have a
2982 superblock and block group descriptor. Used for the
2983 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
2984 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
2985 or not the superblock should be written out for the block
2988 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
2989 for sparse duplicate superblocks.
2991 * version.c (ext2fs_get_library_version): New function which
2992 returns the library version.
2994 * version.c (ext2fs_parse_version_string): New function which
2995 parses a version string and returns a version number,
2996 so application programs can compare version numbers as
2999 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3001 * icount.c (ext2fs_create_icount): Change function so that it also
3002 takes a new argument which contains a "hint" icount
3003 structure. This "hint" icount allows the create function
3004 to set up the sorted list in advance. This reduces
3005 significantly the amount of data moving needed to insert
3006 these inodes into the list later.
3008 * icount.c (ext2fs_icount_validate): New function which validates
3009 that the icount structure's rep invariant.
3011 * icount.c (get_icount_el): Completely revamped implementation
3012 to subsume put_icount_el(). Put_icount_el() used to
3013 use an O(N) implementation to insert in the middle
3014 of the icount list. It now uses a O(ln N) to search
3015 for where the icount should be inserted, and then uses
3016 a memcpy to move the list down (instead of a for loop).
3018 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
3019 ext2fs_icount_increment, ext2fs_icount_decrement): Check
3020 to see if the inode is within bounds; if it isn't, return
3023 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
3024 when a bad inode number is passed to test_generic_bitmap
3025 to be EXT2FS_TEST_ERROR instead of the wrong
3026 EXT2FS_UNMARK_ERROR.
3028 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
3030 * Release of E2fsprogs version 1.07
3032 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3034 * Makefile.in (ELF_VERSION): Change version to be 2.2
3036 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3038 * alloc.c (ext2fs_get_free_blocks): Change routine to use
3039 ext2fs_fast_test_block_bitmap_range().
3041 * bitops.h (ext2fs_fast_test_block_bitmap_range,
3042 ext2fs_test_block_bitmap_range: New inline functions which
3043 test to see whether a contiguous range of blocks is
3046 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3048 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
3049 use ext2fs_badblocks_* instead of badblocks_*
3051 * bb_compat.c: New file which translates between old badblocks_*()
3052 names to ext2fs_badblocks_*()
3054 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
3055 link.c (since e2fsck doesn't use ext2fs_unlink()).
3057 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
3058 bitmap resizing routine moved from bitmaps.c, since e2fsck
3059 doesn't need to use this function.
3061 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
3062 since e2fsck only needs ext2fs_lookup.
3064 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3066 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
3067 already set; this is needed so that programs like dump
3068 which use the inode scan functions will deal with
3069 filesystems that have bad blocks in the inode table.
3071 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3073 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
3074 Moved to ext2fsP.h, since it doesn't need to be part of
3075 the public interface.
3077 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
3079 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3081 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
3082 directory block list abstraction. (Code moved from
3085 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
3086 to inode.c (since no one else should be peeking inside it!)
3088 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
3090 * openfs.c (ext2fs_open): Check the feature set in the ext2
3091 superblock, and refuse to open filesystems if they contain
3092 incompatible features. (Can be overriden with the
3095 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3097 * block.c (ext2fs_block_iterate2): Added new function
3098 ext2fs_block_iterate2 which changes the function
3099 signature of the callback function to include the
3100 referencing block and offset.
3102 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
3103 ext2fs_inode_scan_goto_blockgroup which allows an
3104 application to jump to a particular block group while
3105 doing an inode scan.
3107 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3109 * dirblock.c: Include string.h, since we use memcpy().
3111 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3113 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
3114 a long not an int; this doesn't matter on i386 machines,
3115 but it does on Alpha's.
3117 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3119 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
3120 table pointer is NULL, then return an error indicating
3121 that the inode table is missing.
3122 (get_next_blockgroup, get_next_blocks,
3123 ext2fs_get_next_inode): Don't treat a missing inode table
3124 as permanent error. Return MISSING_INODE_TABLE, but as an
3125 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
3127 * rw_bitmaps.c (ext2fs_write_block_bitmap,
3128 ext2fs_write_inode_bitmap): If the inode or block bitmap
3129 block is zero, then don't write out the inode or block
3130 bitmap. The idea here is to avoid stomping on the
3132 (read_bitmaps): If the inode or block bitmap block is
3133 zero, then fill in that portion of the inode or block
3134 bitmap with all zeros.
3136 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
3137 blocks in inode table when the inode table size is
3138 non-standard (and can therefore span blocks).
3140 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3142 * alloc.c (ext2fs_new_block): Fix fencepost error in
3143 ext2fs_new_block; make sure we don't try to allocate the
3144 first block beyond the end of the filesystem.
3146 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3148 * inode.c (check_for_inode_bad_blocks): New function called by
3149 get_next_blocks() to avoid reading in bad blocks marked in
3150 fs->badblocks. Inodes located in bad blocks are returned
3151 by ext2fs_get_next_inode() returns the error code
3152 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
3154 * alloc_tables.c (ext2fs_allocate_tables): New function which
3155 performs the part of mke2fs's job of allocating the
3158 * test_io.c (test_close): IO manager which is used for testing
3161 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3163 * inode.c (ext2fs_get_next_inode): Separate out the function of
3164 setting up for a new block group to get_next_blockgroup().
3165 Separate out the function of reading in blocks of the
3166 inode table to get_next_blocks().
3168 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
3170 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
3171 blocks to the badblock list in sorted order. This allows
3172 badblocks_list_test to be coded using a binary search for

3182 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
3185 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
3186 set, then only write out the master superblock.
3188 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3190 * block.c (ext2fs_block_iterate): Fixed bug which caused

3226 * namei.c (ext2fs_follow_link): New function.
3227 (ext2fs_namei): Extended to have support for chasing
3228 symbolic links. ext2fs_namei() still returns an inode
3229 which is a symbolic link. Symbolic links are only chased
3230 while resolving the containing directory. To chase
3231 symbolic links of the final result, use
3232 ext2fs_follow_link().
3234 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

3243 * initialize.c (ext2fs_initialize): On systems where the byte
3244 order is not i386 compatible, set the swap_byte flag.
3246 * inode.c (inocpy_with_swap): Check to see if inode contains a
3247 fast symlink before swapping the inode block fields. This
3248 required adding a new argument to inocpy_with_swap to
3249 determine whether the mode field is in host order or not.
3251 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3253 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
3254 the sparc, if EXT2_STD_BITOPS set, use the standard
3255 i386-compatible bitmask operations, instead on the
3256 non-standard native bitmask operators.

3260 * block.c (ext2fs_block_iterate): Cause block iterator to return
3261 the HURD translator block (along with everything else).

3263 iterator, then don't return any meta data blocks
3264 (including the HURD translator).
3266 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3268 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
3270 * uuid.c: New file, containing UUID utility functions.
3272 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

3278 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
3280 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3282 * openfs.c (ext2fs_open): If the blocksize in the superblock is
3283 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
3284 that's a basic value that must be correct for the rest of
3285 the library to work.
3287 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
3290 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

3301 Change the m68k bit numbering for bitmasks to match with
3302 the bit numbering used by all other ext2 implementations.
3304 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
3306 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

3339 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3340 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
3341 to avoid conflicts with with kernel include files. Also
3342 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
3345 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
3347 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c

3367 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
3370 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
3372 * unix_io.c (unix_open): Add a double check; if the passed in name
3373 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
3375 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
3377 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

3385 partition size from a BSD disk label.
3387 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3389 * getsize.c (ext2fs_get_device_size): New function that determins

3399 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
3400 Move these functions to freefs.c.
3402 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
3403 descriptors shadow memory to keep purify quiet. (This
3404 also has the nice benefit that the unused portion of the
3405 shadow descriptors are zeroed out.)
3407 * dirblock.c (ext2fs_write_dir_block): We need to use
3408 dirent->rec_len *before* it's byteswapped to find the
3409 location of the next directory structure!
3411 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
3412 cause ext2fs_new_inode to loop infinitely if we're trying
3413 to allocate an inode in group #0 and there are no free
3414 inodes at all in the system.
3416 * closefs.c: #include <errno.h> if it exists.
3418 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

3437 file containing functions for reading and writing
3438 directory blocks (byte swapping if necesssary)
3440 * block.c (block_iterate_ind, block_iterate_dind,
3441 block_iterate_tind): Byte swap the block addresses if

3447 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
3449 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
3450 the superblock and group descriptors before writing it out.
3452 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
3453 then set the EXT2_SWAP_BYTES and byte-swap the superblock
3454 and group descriptors.
3456 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
3457 to desp ext2 filesystem structures.
3459 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
3460 supplied by Pete A. Zaitcev so that the C language
3461 versions of these functions are more portable. They will
3462 now work on both little and big endian systems, and the
3463 assumption that 32-bit integers are used is gone.
3465 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
3466 doing byte swapping.
3468 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
3469 byte swapping should take place.
3471 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

3482 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
3483 if the magic number is correct, it will be allocated.
3485 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
3487 * block.c (block_iterate_ind, block_iterate_dind,
3488 block_iterate_tind): Don't recompute block_nr each loop;
3489 just increment it! Factor check of BLOCK_FLAG_APPEND out
3490 of the loop. Factor mask of BLOCK_CHANGED into changed
3491 variable out of the loop. (block_iterate_ind, in
3492 particular, gets called a lot, so every little
3493 optimization helps.)
3495 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
3497 * block.c (block_iterate_ind, block_iterate_dind,

3504 ext2fs_fast_test_inode_bitmap): Add fast version of these
3505 functions, which don't do range checking.

3509 ext2fs_get_inode_bitmap_end): Add new accessor functions
3510 which return the start and end points of the bitmaps.
3512 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
3514 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
3515 instead of llseek. The errno if the offset is too large
3516 and lseek is not supported should be EINVAL, not -EINVAL.
3518 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
3520 * Makefile.in: Added support for ELF shared libraries.
3521 Fixed typos in the compilation rules.
3522 (distclean): Added Makefile.
3524 * llseek.c (llseek): New function, if llseek() does not exist in the

3536 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
3537 the S_*, which are normally defined in <sys/stat.h>. This
3538 allows us to compile e2fsprogs on a non-Linux system,
3539 which may have a different value for S_IFDIR.
3541 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3543 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
3544 this is a user-mode application!
3546 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
3548 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
3549 __linux__ so that non-linux systems won't see it.
3551 * alloc.c: Include <errno.h> if possible.
3552 * badblocks.c: Ditto.
3553 * bb_inode.c: Ditto.
3556 * expanddir.c: Ditto.

3573 * initialize.c (ext2fs_initialize): Don't allow more than one
3574 bitmaps's worth of inodes in a group.
3576 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
3578 * llseek.c (ext2_llseek): Added error checking to the llseek()
3579 compat code to protect against overflow. This only
3580 applies to 1.0 and early 1.1 kernels, which don't support
3581 the llseek() system call.
3583 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
3585 * unix_io.c (unix_open): Initialize the read_error and write_error
3586 io_channel pointers to be null.
3588 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
3589 found, clear it but don't try to update the filesystem
3590 accounting information, since that's hopeless anyway.
3592 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
3593 bloblock_iterate_tind): Check to see if the indirect blocks are
3594 valid before trying to read them.

3600 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
3601 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
3602 illegal block or inode number is passed in, return instead
3603 of trying to test, set, or clear the bit.
3605 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
3607 * Makefile: Added a dummy install target in case shared libraries

3664 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
3669 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
3670 openfs.c into its own file.
3672 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
3673 structure magic numbers.
3675 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
3676 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
3677 someone uses the -b option to specify the use of the backup
3678 superblock --- this usually means that the main superblock is
3682 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
3683 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
3684 revision level to the superblock.

3693 * initialize.c: Completely revamped the inode and block bitmap
3694 structures, so that they can be better chance of being extensible
3695 in a shared library. They are now their own type, instead of
3696 being a char *. Also, the function signatures of
3697 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
3698 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
3699 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
3700 changed to eliminate the ext2_filsys argument, since it is no
3703 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
3705 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
3706 system call if available.
3708 * llseek.c: new file. This is the stub calling the llseek system
3709 call which allows supports for 2GB+ file systems.
3711 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
3712 the creator operating system.
3714 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
3716 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
3717 the group descriptor statistics in addition to everything else.
3718 This relieves mke2fs of the responsibility of doing it.
3720 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
3721 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
3722 not the generic C function equivalents should be included or not.
3724 * openfs.c (ext2fs_open): If a superblock is specified, then use
3725 the backup group descriptors that go along with this superblock,
3726 instead of using the primary group descriptors. This allows
3727 e2fsck to recover filesystems where the primary group descriptors
