12 2007-04-04 Theodore Tso <tytso@mit.edu>
14 * tdb.c, tdb.h, Makefile.in: Add the tdb library from Samba into
17 * tst_types.c: Add #include's to avoid compiler warnings.
19 2007-04-02 Theodore Tso <tytso@mit.edu>
21 * icount.c (get_icount_el): Prevent floating point precision
22 errors on really big filesystems from causing the search
23 interpolation algorithm loop forever. (Addresses Debian
26 2007-03-21 Theodore Tso <tytso@mit.edu>
28 * imager.c (ext2fs_image_inode_write), inode.c
29 (ext2fs_write_inode_full): Fix memory leak on error return
30 (when the inode table is missing).
32 2006-11-30 Theodore Tso <tytso@mit.edu>
34 * ext2_fs.h (struct ext4_group_desc): Fix missing bg_pad which
35 made the structure too small.
37 2006-11-14 Theodore Tso <tytso@mit.edu>
39 * namei.c (open_namei): Rename internal variable basename to
40 base_name to prevent gcc -Wall complaints.
42 * kernel-jbd.h (tid_gt, tid_geq): Add function declaration to
43 avoid gcc -Wall complaints.
45 * ext2_ext_attr.h (EXT2_EXT_ATTR_PAD): Make unsigned to fix gcc
48 * bitops.h (ext2fs_test_bit): Add missing const to fix gcc -Wall
51 * ext2fs.h (ext2fs_get_mem, ext2fs_free_mem): Avoid type punning
52 which causes problems on the ARM processor. (Addresses
55 2006-11-12 Theodore Tso <tytso@mit.edu>
57 * ext2_fs.h (EXT2_FLAG_SOFTSUPP_FEATURES), openfs.c
58 (ext2fs_open2): Add flag which indicates that it's OK to
59 open a filesystem which has features which are only
60 partially supported by e2fsprogs.
62 * ext3_extents.h, ext2fs.h: Check in ext4 extent headers into the
63 source tree, in preparation for adding full extent support.
65 * unix_io.c (unix_flush): Allow offsets greater than 2G.
66 (Addresses SourceForge Bug #1547922)
68 2006-11-11 Theodore Tso <tytso@mit.edu>
70 * dirhash.c (str2hashbuf, ext2fs_dirhash): Add support for
71 calculating the unsigned version of the directory hash.
73 * initialize.c (ext2fs_initialize): Set the dirhash
74 signed/unsigned hint in s_flags.
76 * swapfs.c (ext2fs_swap_super): Byte swap the s_flags superblock
79 * ext2_fs.h: Define a new superblock field, s_flags, which is used
80 to store a signed vs. unsigned dirhash hint. Define new
81 HTREE hash algorithm numbers to pass to userspace if the
82 unsigned algorithm are required.
84 * swapfs.c (ext2fs_swap_super):
85 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE,
86 which adds s_min_extra_isize and s_want_extra_isize fields
87 to superblock, which allow specifying the minimum and
88 desired i_extra_isize fields in large inodes
89 (for nsec+epoch timestamps, potential other uses).
90 Needs RO_COMPAT flag handling, needs e2fsck support,
91 patch complete, little testing.
93 * swapfs.c (ext2fs_swap_super):
94 ext2_fs.h: Add definition of EXT4_FEATURE_INCOMPAT_64BIT,
95 which adds supports for 64-bit block count fields in the
96 superblock (s_blocks_count_hi, s_free_blocks_count_hi),
97 large group descriptors (s_desc_size), extents with high
98 16 bits (ee_start_hi, ei_leaf_hi), inode ACL (i_file_acl_hi)
100 * ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_DIR_NLINK,
101 which allow directories to have > 65000 subdirectories
102 (i_nlinks) by setting i_nlinks = 1 for such directories.
103 RO_COMPAT protects old filesystems from unlinking such
104 directories incorrectly and losing all files therein.
106 * swapfs.c (ext2fs_swap_group_desc):
107 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
108 which adds a crc16 checksum in the group descriptor,
109 (s_uuid[16] | __u32 group | ext3_group_desc
110 (excluding gd_checksum itself)). This allows the kernel
111 to more safely manage UNINIT groups. Also adds an
112 bg_itable_unsued which indicates how many inodes are
113 uninitialized in the block group.
115 * swapfs.c (ext2fs_swap_inode_full):
116 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_HUGE_FILE,
117 which changes i_blocks to be in units of s_blocksize units
118 instead of 512-byte sectors, use l_i_frag and l_i_fsize as
121 2006-10-02 Eric Sandeen <esandeen@sandeen.net>
123 * getsize.c (ext2fs_get_device_size): Check to make sure that the
124 number of blocks doesn't overflow the retblocks return
125 parameter for regular files using stat64().
127 2006-10-01 Theodore Tso <tytso@mit.edu>
129 * bitops.h (ext2fs_swab32): Only include ext2fs_swab32() if
130 EXT2FS_ENABLE_SWAPFS is defined.
132 2006-08-30 Eric Sandeen <esandeen@redhat.com>
134 * initialize.c (ext2fs_initialize): Make sure inode count does
135 not overflow 32 bits.
137 2006-08-30 Eric Sandeen <esandeen@redhat.com>
139 * alloc_tables.c (ext2fs_allocate_group_table):
140 * check_desc.c (ext2fs_check_desc):
141 Use new inlines to calculate group first & last blocks.
143 Create new inlines to calculate first/last group blocks.
145 2006-08-30 Eric Sandeen <esandeen@redhat.com>
147 * bmove.c (process_block):
149 * icount.c (ext2fs_create_icount2, insert_icount_el):
150 * tst_badblocks.c (print_list, validate_test_seq, do_test_seq):
151 * tst_badblocks.c (invalid_proc):
152 * tst_getsize.c (main):
153 * tst_iscan.c (check_map):
154 * unix_io.c (raw_read_blk, unix_read_blk):
155 * write_bb_file.c (ext2fs_write_bb_FILE): Fix printf formats.
157 2006-08-30 Eric Sandeen <esandeen@redhat.com>
159 * closefs.c (write_backup_super):
160 * initialize.c (ext2fs_initialize): Remove unused variables.
162 2006-08-30 Eric Sandeen <esandeen@redhat.com>
164 * check_desc.c (ext2fs_check_desc): avoid overflows when iterating
165 over group descriptors on very large filesystems.
167 2006-08-30 Theodore Tso <tytso@mit.edu>
169 * bitmaps.c (ext2fs_set_bitmap_padding): Fix potential overflow
170 problems when the number of blocks is close to 2**31.
172 * ext2fs.h (ext2fs_div_ceil): Add new function which safely
173 calculates an integer division where the result is always
174 rounded up while avoiding overflow errors.
176 * initialize.c (calc_reserved_gdt_blocks, ext2fs_initialize):
177 * openfs.c (ext2fs_open2): Use ext2fs_div_ceil() instead of a
178 using an open-coded expression which was subject to
181 2006-08-06 Andreas Dilger <adilger@clusterfs.com>
183 * bitops.h (ext2fs_cpu_to_le32, ext2fs_le64_to_cpu,
184 ext2fs_swab64): Add 64-bit byte swapping functions
186 2006-08-05 Theodore Tso <tytso@mit.edu>
188 * ext2_fs.h (EXT4_EXTENTS_FL): Rename EXT3_EXTENTS_FL to
189 EXT4_EXTENTS_FL, and add EXT4_EXTENTS_FL to user visible
192 2006-07-15 Theodore Tso <tytso@mit.edu>
194 * ext2fs.h: Remove unneeded #ifdef since EXT2_DYNAMIC_REV is
195 always defined in the e2fsprogs-provided ext2_fs.h
197 2006-05-21 Theodore Tso <tytso@mit.edu>
199 * openfs.c (ext2fs_open2): Fix type warning problem with sizeof()
201 2006-05-12 Theodore Tso <tytso@mit.edu>
203 * alloc_tables.c (ext2fs_allocate_group_table): When allocating
204 space for the RAID filesystems with the stride parameter,
205 place each portion of the group's inode table right up
206 after the superblock (if present) in order to minimize
207 fragmentation of the freespace.
209 2006-05-08 Theodore Tso <tytso@mit.edu>
211 * rw_bitmaps.c (write_bitmaps, read_bitmaps): Added support for
212 lazy blockgroups. If a block group has flags indicating
213 that its block or inode data structures have not been
214 initialized, skip reading or writing that portion of the
217 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode_full): When
218 scanning a filesystem with lazy blockgroups, skip
219 uninitialized portions of the inode table when iterating
220 over the block group.
222 * swapfs.c (ext2fs_swap_group_desc): Byte swap the bg_flags field.
224 * ext2fs.h: Define the a new internal flag, EXT2_SF_DO_LAZY, so
225 that the inode interator knows compat_lazy_bg feature is
226 enabled. Declare that this version of e2fsprogs supports
227 the EXT2_FEATURE_COMPAY_LAZY_BG feature.
229 * ext2_fs.h (struct ext2_group_desc): Use the bg_pad field for
230 bg_flags, and define the flags EXT2_BG_INODE_UNINIT and
231 EXT2_BG_BLOCK_UNINIT. These flags are only honored if
232 EXT2_FEATURE_COMPAT_LAZY_BG feature is enabled (also
235 2006-04-23 Theodore Ts'o <tytso@mit.edu>
237 * rw_bitmaps.c (write_bitmaps, ext2fs_write_inode_bitmap,
238 ext2fs_write_block_bitmap, ext2fs_write_bitmaps): Reduce
239 disk seeks by writing the inode and block bitmaps in an
242 2006-04-09 Theodore Ts'o <tytso@mit.edu>
244 * ext2_types.h.in, Makefile.in, tst_types.c: Use the asm_types.h
245 file to define the __[us]{8,16,32,64} types. Add a
246 tst_types program to make sure the types are correct.
248 2006-04-04 Theodore Ts'o <tytso@mit.edu>
250 * mkjournal.c (ext2fs_add_journal_inode): If the filesystem is
251 opened in exclusive mode, then device will be busy by
252 definition, so don't return -EBUSY. This caused mke2fs -j
253 to fail on the 1.39-WIP (29-Mar-2006) release. (Addresses
256 2006-03-29 Theodore Ts'o <tytso@mit.edu>
258 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit): Fix the constraints
259 so that GCC knows that the ext2fs_set/clear_bit reads and
262 2006-03-25 Theodore Ts'o <tytso@mit.edu>
264 * Makefile.in: Check the bitfield operations much more carefully,
265 and arrange to have tst_bitops run from "make check"
267 * tst_bitops.c: Enahce tst_bitops program so that it is much more
268 thorough in testing bit optations.
270 * bitops.h: Add new functions ext2fs_fast_set_bit() and
271 ext2fs_fast_clear_bit() and make the x86 functions 32-bit
272 clear. Change the fast inode and block mark/unmark
273 functions to use ext2fs_fast_set/get_bit()
275 2006-03-18 Theodore Ts'o <tytso@mit.edu>
277 * ext2fs.h (EXT2_FLAG_EXCLUSIVE): Define new flag which requests
278 that the io_channel be opened in exclusive mode.
280 * openfs.c (ext2fs_open2), initialize.c (ext2fs_initialize): If
281 EXT2_FLAG_EXCLUSIVE is passed to ext2fs_open or
282 ext2fs_initialize, then pass IO_FLAG_EXCLUSIVE to the
283 io_channel open routine.
285 * ext2_io.h (IO_FLAG_EXCLUSIVE), unix_io.c (unix_open): Add new
286 io_channel open flag, IO_FLAG_EXCLUSIVE, which requests
287 that the device be opened in exclusive (O_EXCL) mode.
289 * ext2fs.h: Fix documentation so that BLOCK_FLAG_TRAVERSE is
290 BLOCK_FLAG_DEPTH_TRAVERSE. (Addresses Debian Bug #351268)
292 2006-03-17 Theodore Ts'o <tytso@mit.edu>
294 * initialize.c (calc_reserved_gdt_blocks): Fix a signed vs
295 unsigned problem which caused mke2fs -O resize_inode to
296 bomb out on large filesystems. (Addresses Debian Bug
299 * ext2_fs.h (EXT2_IOC_GETVERSION_NEW, EXT2_IOC_SETVERSION_NEW,
300 EXT2_IOC_GROUP_EXTEND, EXT2_IOC_GROUP_ADD): Add ioctl
303 2005-12-10 Theodore Ts'o <tytso@mit.edu>
305 * Makefile.in: Add a dependency to make sure that the
306 subdirectories are created before creating all of the
309 2005-12-10 Theodore Ts'o <tytso@mit.edu>
311 * res_gdt.c (ext2fs_create_resize_inode): Fix type-punning warning.
313 * read_bb_file.c (ext2fs_read_bb_FILE): Use a data structure
314 instead of stuffing a function pointer dirctly into a void
315 pointer, since that isn't portable.
317 * mkjournal.c (ext2fs_add_journal_inode): Fix possiblely
318 uninitialized use of variable warning.
320 * initialize.c (calc_reserved_gdt_blocks): Fix signed vs. unsigned
323 * ext2fs.h: Make the type of the 'now' field to be time_t to avoid
324 gcc -Wall complaints.
326 * bitops.h (ext2fs_find_first_bit_set): Fix signed vs unsigned
329 * tst_badblocks.c (file_test_invalid): Add test which confirms
330 proper detection of invalid block numbers in
331 ext2fs_read_bb_FILE().
333 2005-11-20 Theodore Ts'o <tytso@mit.edu>
335 * bitops.h: We no longer have the sparc assembly code in the
336 header file any more, so we shouldn't set
337 _EXT2_HAVE_AS_BITOPS_. This would break compiles on the
338 sparc architectures when using gcc.
340 2005-11-13 Theodore Ts'o <tytso@mit.edu>
342 * ext2fs.h: Add #include <string.h> since the inline functions use
343 memcpy(). (Addresses Sourceforge Bug #1251062)
345 2005-11-09 Theodore Ts'o <tytso@mit.edu>
347 * Fix a bug when writing an external journal device on an big
348 endian machine (such as a S/390), where when the number of
349 block groups is zero, we never end up writing out the
350 primary superblock at all.
352 2005-09-24 Theodore Ts'o <tytso@mit.edu>
354 * ext2fs.h, bb_inode.c, closefs.c, initialize.c, mkdir.c,
355 mkjournal.c, res_gdt.c: If fs->now is non-zero, use that
356 as the time instead of the system time when setting
357 various filesystem fields (last modified time, last write
360 2005-08-28 Matthias Andree <matthias.andree@gmx.de>
362 * Fix compiler warnings about missing memcpy prototypes.
364 2005-07-25 Theodore Ts'o <tytso@mit.edu>
366 * test_io.c (safe_getenv): Pass in zero to the unusued arguments
367 of prctl(PR_GET_DUMPABLE) to avoid false positives from
370 2005-07-19 Theodore Ts'o <tytso@mit.edu>
372 * mkjournal.c (ext2fs_add_journal_inode): Check for the case where
373 the filesystem is apparently not mounted, but the device
374 is still busy. This can happen when the luser doesn't
375 bother to mount /proc and has a bogus /etc/mtab, but still
376 wants to mount the filesystem before using tune2fs(?!?).
377 Add a safety check to save him from his own stupidity, at
378 least on 2.6 kernels. (Addresses Debian Bug #319002)
380 2005-07-09 Andreas Dilger <adilger@clusterfs.com>
382 * getsize.c (ext2fs_get_device_size): Use fstat/fstat64 to get
383 size of regular files. Fix file descriptor leaks in error
386 2006-06-30 Theodore Ts'o <tytso@mit.edu>
388 * Release of E2fsprogs 1.38
390 2005-06-30 Theodore Ts'o <tytso@mit.edu>
392 * bitops.h, bitops.c (ext2fs_set_bit, ext2fs_clear_bit,
393 ext2fs_test_bit): Change these function prototypes to be
394 unsigned int's. Negative bit numbers were never allowed
395 (and never made any sense), so this should be a safe
396 change. This is needed to allow safe use of block numbers
397 greater than or equal to 2**31.
399 2005-06-27 Stephen Tweedie <sct@redhat.com>
401 * ext2fs.h (ext2fs_resize_mem): Fix C99 strict type aliasing
402 problems. Addresses Red Hat Bugzilla #161183.
404 2005-06-19 Theodore Ts'o <tytso@mit.edu>
406 * getsectsize.c (BLKSSZGET): Clean up test for when to manually
407 define the BLKSSZGET ioctl.
409 2005-05-29 Theodore Ts'o <tytso@mit.edu>
411 * ismounted.c (ext2fs_check_mount_point): Add test to see if the
412 device appears to be busy; this only works on Linux 2.6+
413 systems, but provides some additional bullet-proofing in
416 2005-05-08 Theodore Ts'o <tytso@mit.edu>
418 * test_io.c (safe_getenv): Fix bug so it would fetch the right
419 environment variable.
421 2005-04-09 Theodore Ts'o <tytso@mit.edu>
423 * inode.c (ext2fs_write_new_inode),
424 ind_block.c (ext2fs_read_ind_block): Add missing return
425 value in error return case. (Otherwise we return garbage
426 instead of the error code.)
428 2005-03-31 Theodore Ts'o <tytso@mit.edu>
430 * test_io.c (test_open): If called by a setuid/setgid or an
431 otherwise privileged program, be paranoid and ignore the
432 TEST_IO_* environment variables.
434 2005-03-21 Theodore Ts'o <tytso@mit.edu>
436 * Release of E2fsprogs 1.37
438 2005-03-21 Theodore Ts'o <tytso@mit.edu>
440 * ext2_ext_attr.h (EXT2_XATTR_LEN, EXT2_XATTR_SIZE): Add new
441 convenience cpp macros.
443 2005-03-20 Theodore Ts'o <tytso@mit.edu>
445 * mkdir.c (ext2fs_mkdir): Call ext2fs_write_new_inode() instead of
446 ext2fs_write_inode().
448 * inode.c (ext2fs_write_new_inode): New function which should be
449 used when the caller is writing an inode for the first
450 time. It makes sure that the extra portion of the large
451 inode is initialized properly.
453 2005-03-18 Theodore Ts'o <tytso@mit.edu>
455 * Makefile.in: Fix clean target to remove tst_getsectsize.
457 * getsize.c (ext2fs_get_device_size): Check to see if the number
458 of blocks is greater than 2**32 when we are doing a binary
459 search to determine the device size. Thanks to Stephen
460 Tweedie for the patch.
462 2006-02-05 Theodore Ts'o <tytso@mit.edu>
464 * Release of E2fsprogs 1.36
466 2005-02-05 Theodore Ts'o <tytso@mit.edu>
468 * Makefile.in: Remove ext2fs.pc on a "make distclean"
470 2005-02-04 Theodore Ts'o <tytso@mit.edu>
472 * Makefile.in (clean): Remove tst_getsize when doing a make clean
474 2005-02-03 Theodore Ts'o <tytso@mit.edu>
476 * bitops.c: Make the generic functions more efficient.
478 * bitops.h: Drop SPARC assembly code. It's less efficient than GCC
479 3.4 compiled code and also triggers nasty compiler
480 warnings on sparc64. Thanks to Matthias Andree for his
481 analysis and suggestion.
483 2005-01-27 Theodore Ts'o <tytso@mit.edu>
485 * res_gdt.c (ext2fs_create_resize_inode): Create the resize inode
486 even if s_reserved_gdt_blocks is zero.
488 2005-01-26 Theodore Ts'o <tytso@mit.edu>
490 * ext2fs.pc.in: Add pkg-config files.
492 2005-01-25 Theodore Ts'o <tytso@mit.edu>
494 * ext2fs.h: Add definition of struct ext2_inode_large
496 * ext2_fs.h: Add new function prototypes
498 * ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr): The
499 ext2fs_swap_ext_attr() has been moved to swapfs.c, and
500 given a new argument, has_header.
502 * swapfs.c (ext2fs_swap_ext_attr): Moved from ext_attr.c, and
503 takes an argument which controls whether or not there is
504 an EA header which needs to be byteswaped.
505 (ext2fs_swap_inode_full): New function which byte-swaps
508 * inode.c (ext2fs_get_next_inode_full, ext2fs_read_inode_full,
509 ext2fs_write_inode_full): New functions, originally from
510 Alex Tomas, but which needed to be substantially fixed so
511 that the tests wouldn't cause major stack overwrite bugs
512 in byte-swapping is enabled.
514 2005-01-18 Theodore Ts'o <tytso@mit.edu>
516 * Makefile.in: Fix the kernel compile-time echo commands to be
517 consistent and portable
519 2005-01-07 Theodore Ts'o <tytso@mit.edu>
521 * unlink.c (ext2fs_unlink): If both the name and the inode number
522 are unspecified, then return an error, so that we don't do
523 something surprising such as unconditionally deleting the
524 first directory entry.
525 (unlink_proc): Delete directory entries by coalescing it
526 with the previous entry, to avoid directory fragmentation.
528 2005-01-06 Theodore Ts'o <tytso@mit.edu>
530 * version.c (ext2fs_parse_version_string): Change parsing
531 algorithm so that version strings such as 1.36-rc1 returns
532 a non-surprising result (i.e., 136, and not 1361).
534 2005-01-05 Theodore Ts'o <tytso@mit.edu>
536 * block.c (block_iterate_ind, block_iterate_dind,
537 block_iterate_tind): Move the code which byte swaps and
538 read/writes indirect blocks to ext2fs_{read,write}_ind_block.
539 This saves 400 bytes, and we need them for the
540 resize_inode handling.
542 * ind_block.c (ext2fs_read_ind_block, ext2fs_write_ind_block): New
545 * res_gdt.c (ext2fs_create_resize_inode): Use
546 ext2fs_{read,write}_ind_block so that byte swapping is
547 handled on big-endian systems.
549 * dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handle
550 has its own copy of the orig_super data structure. (This
551 is a better way of fixing a double-free problem in
552 resize2fs which Fedora attempted to fix in
553 e2fsprogs-1.35-double_free.patch. Addresses Red Hat
556 2004-12-23 Theodore Ts'o <tytso@mit.edu>
558 * inode.c (ext2fs_flush_icache): When flushing the icache, clear
559 the last-read block information as well.
561 * ext2fs.h (BMAP_SET), bmap.c (ext2fs_bmap): Add support for new
562 flag, BMAP_SET, which allows the caller to set a
563 particular logical->physical block mapping.
565 * ext2_err.et.in (EXT2_ET_SET_BMAP_NO_IND): New error code
567 * initialize.c (calc_reserved_gdt_blocks): #ifdef out all
568 debugging printf statements.
570 * res_gdt.c (ext2fs_create_resize_inode): Return
571 EXT2_ET_RESIZE_INODE_CORRUPT if the resize inode is not
572 what we expect. #ifdef out all debugging printf
575 * ext2_err.et.in (EXT2_ET_RESIZE_INODE_CORRUPT): Add new error code.
577 2004-12-22 Theodore Ts'o <tytso@mit.edu>

585 res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
586 ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
587 ext2fs_bg_has_super() back to closefs.c. There's no
588 reason for the new file, since list_backups() isn't being
589 used by any other functions, and can be made static, and
590 all users of the ext2fs filesystem will have to call
591 ext2fs_close() anyway.
593 2004-12-15 Theodore Ts'o <tytso@mit.edu>
595 * Applied resize inode patch from Andreas Dilger
597 * res_gdt.c (ext2fs_create_resize_inode): New function that

604 EXT2_FEATURE_COMPAT_RESIZE_INODE to the list of supported
606 Add function prototypes for res_gdt.c and sparse.c.
608 * closefs.c (ext2fs_super_and_bgd_loc): Take the reserved blocks
609 into account when calculating the number of overhead
612 * closefs.c (ext2fs_bg_has_super, test_root), sparse.c: Move these
613 functions to the new file sparse.c
615 * alloc_sb.c (ext2fs_reserve_super_and_bgd): Reserve the blocks
616 saved in the resize inode as being in use.
618 * ext2_err.et.in (EXT2_ET_RES_GDT_BLOCKS): Add new error code.

635 * test_io.c (test_set_option): Add support for the set_option method.
637 * ext2_io.h: Add new io_channel method, set_option(), and change
638 io_channel_write_byte() from a macro to a library function.
640 * ext2fs.h, openfs.c(ext2fs_open2): New version of ext2fs_open
641 which adds a new parameter, io_options.
642 (ext2fs_open): If there is a question mark in the
643 filename, and no io_options are specified, assumed that
644 the text following the question mark are io_options.
646 * io_manager.c, Makefile.in: New source file which contains
647 high-level functions for the io_channel layer.
649 * freefs.c (ext2fs_free): Make sure we don't free the io_channel
652 * Makefile.in: Use Linux-kernel-style makefile output to make it
653 easier to see errors/warnings.
655 2004-11-29 Theodore Ts'o <tytso@mit.edu>
657 * ext2_fs.h (EXT2_EXTENTS_FL, EXT3_FEATURE_INCOMPAT_EXTENTS,
658 EXT2_MAX_BLOCK_LOG_SIZE): Add definition for extent
659 feature and inode flag. Change maximum allowable block
662 2004-10-08 Theodore Ts'o <tytso@mit.edu>
664 * getsize.c (ext2fs_get_device_size): Add support for Windows
665 9x/NT under Cygwin. Thanks to Sam Robb
666 (samrobb@users.sourceforge.net) for pointing this and the
667 suggested code patch.

678 * rw_bitmaps.c (read_bitmaps), block.c (block_iterate_ind,
679 block_iterate_dind, block_iterate_tind), inode.c
680 (ext2fs_read_inode): If EXT2_FLAG_IMAGE_FILE is set, so
681 read the metadata from fs->image_io instead of fs->io.
683 * initialize.c (ext2fs_initialize), openfs.c (ext2fs_open):
684 Initialize fs->image_io to be the same as fs->io.
686 * ext2_err.et.in (EXT2_ET_NOT_IMAGE_FILE): Add new error code.
688 * openfs.c (ext2fs_get_data_io, ext2fs_set_data_io,
689 ext2fs_rewrite_to_io): New functions that allow
690 applications to manipulate fs->image_io and fs->io safely.
692 * freefs.c (ext2fs_free): If fs->image_io is different fs->io,
693 then call io_channel_close on fs->image_io.
695 * ext2fs.h: Add image_io element to the ext2_filsys data
696 structure. Add ext2fs_get_data_io() ext2fs_set_data_io(),
697 and ext2fs_rewrite_to_io() prototypes.
699 2004-05-26 Theodore Ts'o <tytso@mit.edu>
701 * closefs.c (ext2fs_flush): Make sure the master superblock is
702 written last, and only after other I/O has been flushed to
703 disk. Thanks to Junfeng Yang from the Stanford
704 Metacompilation group for pointing a potential ordering
705 constraint problem if we don't write things out in the
708 * test_io.c: Implement the ability to abort after n reads or
709 writes to a particular block. The block is specified by
710 TEST_IO_BLOCK environment variable, and the read/write
711 count by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT
712 environment variables. The block data is now only dumped
713 if the 0x10 bit is set in TEST_IO_FLAGS.
715 2004-04-03 Theodore Ts'o <tytso@mit.edu>
717 * ext2_types.h.in: Remove check for _UUID_TYPES since uuid_types.h
720 2004-03-08 Theodore Ts'o <tytso@mit.edu>
722 * getsize.c (ext2fs_get_device_size): Only use the BLKGETSIZE64
723 ioctl on Linux 2.6 since it is unreliable in Linux 2.4.
724 (Addresses Debian Bug #236528). Fix typo in the ioctl
727 2004-03-02 Theodore Ts'o <tytso@mit.edu>
729 * getsize.c (ext2fs_get_device_size): Update getsize functions to
730 use Apple Darwin and Linux 64-bit ioctl's
732 2004-02-29 Brian Bergstrand <brian@bergstrand.org>
734 * Makefile.in: Use $(BSDLIB_PIC_FLAG) to determine whether to use

755 which we're using due to a typo in the e2fsck code. (Oops)
757 * swapfs.c (ext2fs_swap_inode): Fix byte swap bug which causes SE
758 Linux created symlinks with mandatory attributes to fail
759 to be properly handled on big endian systems. (Addresses
761 (ext2fs_swap_super): Byte swap some new fields in the
762 superblock, including the journal backup fields.
764 2003-12-02 Theodore Ts'o <tytso@mit.edu>
766 * alloc.c, bb_inode.c, bitops.c, block.c, check_desc.c, closefs.c,

770 rw_bitmaps.c, unix_io.c, unlink.c, write_bb_file.c: Fix
771 gcc -Wall complaints. Mainly marking variables as being
772 unsued, and catching signed vs. unsigned comparisons.

776 * closefs.c (ext2fs_super_and_bgd_loc): New function which
777 centralizes the calculation of the superblock and block
779 (ext2fs_flush): Use ext2fs_super_and_bgd_lock to figure
780 out where to write the superblock and block group
783 * alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
784 reserves space in the block bitmap using
785 ext2fs_super_and_bgd_loc.
787 * initialize.c (ext2fs_initialize): Use
788 ext2fs_reserve_super_and_bgd to initialize the block bitmap.
790 2003-08-20 Theodore Ts'o <tytso@mit.edu>
792 * inode_io.c (ext2fs_inode_io_intern2), ext2fs.h: Add new function
793 allows the caller to pass in the inode data structure.
795 * fileio.c (ext2fs_file_open2), ext2fs.h: Add new function which
796 allows the caller to pass in the inode to be used in the
799 * ext2_fs.h: Add a backup of the location of the journal inode
800 blocks to the superblock.
802 * mkjournal.c (write_journal_inode): Save the location of the
803 journal inode to the backup location in the superblock.
805 2003-08-01 Philipp Thomas <pthomas@suse.de>

812 mkjournal.c, namei.c, newdir.c, openfs.c, rs_bitmap.c,
813 rw_bitmaps.c, test_io.c, unix_io.c: ext2fs_getmem(),
814 ext2fs_free_mem(), and ext2fs_resize_mem() all now take a
815 'void *' instead of a 'void **' in order to avoid pointer
816 aliasing problems with GCC 3.x.
818 2003-07-25 Theodore Ts'o <tytso@mit.edu>
820 * Release of E2fsprogs 1.34
822 2003-07-06 Theodore Ts'o <tytso@mit.edu>
824 * kernel-jbd.h, flushb.c: Fix gcc -Wall nitpicks (indented cpp
827 * ext2_types.h.in, initialize.c: Fix gcc -Wall nitpicks
830 * ismounted.c: Fix gcc -Wall nitpicks (Don't use exit as a goto label)

834 * lookup.c, read_bb.c: Fix gcc -Wall nitpicks (indent
835 non-traditional #pragma)
837 * test_io.c: Fix gcc -Wall nitpicks (const/unsigned type issues)
839 2003-06-24 <tytso@snap.thunk.org>
841 * badblocks.c, ext2fs.h (ext2fs_u32_list_find,

852 2003-05-13 Theodore Ts'o <tytso@mit.edu>
854 * unix_io.c: Add #ifdef NO_IO_CACHE which disables all userspace
855 caching by the unix_io layer. Not enabled, only for
858 2003-05-05 Theodore Ts'o <tytso@mit.edu>
860 * test_io.c: Pay attention to the environment variables
861 TEST_IO_LOGFILE, TEST_IO_FLAGS, and TEST_IO_BLOCK to
862 determine whether or not we should log io activity, and to
865 2003-05-03 Theodore Ts'o <tytso@mit.edu>
867 * tst_badblocks.c (file_test): Use tmpfile() instead of mktemp().
869 2003-04-29 Theodore Ts'o <tytso@mit.edu>
871 * getsize.c (ext2fs_get_device_size): Allow windows code to get
872 the resize for filesystems that are in regular files.
874 2003-04-21 Theodore Ts'o <tytso@mit.edu>
876 * Release of E2fsprogs 1.33
878 2003-04-21 Theodore Ts'o <tytso@mit.edu>
880 * Makefile.in: Use DYLD_LIBRAY_PATH so that "make check" works on
881 Darwin systems when building with shared libraries.
883 2003-04-18 Theodore Ts'o <tytso@mit.edu>
885 * unix_io.c: Use __CYGWIN__ instead of CYGWIN.

891 2003-04-12 Theodore Ts'o <tytso@mit.edu>
893 * unix_io.c (raw_read_blk): Add Cygwin support (the Windows block
894 device only accepts sector aligned read requests.
896 * ismounted.c (check_mntent_file): Deal with OS's that don't
899 * imager.c: If the OS doesn't define ssize_t, typedef it to int.
901 2003-04-11 Theodore Ts'o <tytso@mit.edu>
903 * ext2_fs.h (EXT2_FEATURE_RO_COMPAT_BTREE_DIR): Comment out unused
906 2003-03-30 Theodore Ts'o <tytso@mit.edu>
908 * Makefile.in: Use the compile_et --build-tree option.

916 which returns the number of entries in the list.
918 2003-03-10 Theodore Ts'o <tytso@mit.edu>
920 * fileio.c (ext2fs_file_lseek): Fix bug added when adding 64-bit
921 support; avoid null dereference when ret_pos is NULL.
923 2003-03-06 Theodore Tso <tytso@mit.edu>
925 * ext2_types.h.in: Don't redefine types if other e2fsprogs
926 *_types.h files have been included already.
928 * kernel-jbd.h: Use C99 variadic cpp macros if not using GCC.
929 (Older GCC's don't support the C99 variadic macros.)
931 * flushb.c (ext2fs_sync_device),
932 ismounted.c (ext2fs_check_mount_point): Avoid GCC extension:
933 #warning not supported by Solaris suncc
935 * ext2_ext_attr.h: Avoid GCC extension: 0 length arrays in
936 structure definition. Not needed for now in
939 2003-01-25 Theodore Ts'o <tytso@mit.edu>
941 * dirhash.c: Fix gcc -Wall nits.
943 2003-01-22 Theodore Ts'o <tytso@mit.edu>

947 2003-01-21 Theodore Ts'o <tytso@mit.edu>
949 * fileio.c (ext2fs_file_read, ext2_file_lseek,
950 ext2_file_get_size): Add 64-bit support.
952 * ext2fs.h (EXT2_I_SIZE): Add macro which caluates a 64bit size
953 from i_size and i_size_high.
955 2003-01-19 Theodore Ts'o <tytso@mit.edu>
957 * initialize.c (ext2fs_initialize): If the user specifies a really
958 large number of inodes, then reduce the number of blocks
959 per group until we find a workable set of filesystem
962 * ext2_err.et.in (EXT2_ET_TOO_MANY_INODES): Add new error code.
964 2002-11-09 Theodore Ts'o <tytso@mit.edu>
966 * Release of E2fsprogs 1.32
968 2002-11-09 Theodore Ts'o <tytso@mit.edu>
970 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
971 unix_write_blk): Optimize routines so that we don't end up
972 searching the cache twice when a block isn't in the
973 cache. If reads are larger than READ_DIRECT_SIZE, don't
974 let them go through the cache.
976 * unix_io.c (find_cached_block): Fixed bug which caused some clean
977 blocks to be erroneously marked as dirty, so they would
978 get written back to the disk before they are evicted from
979 the cache. Harmless, but it slows down e2fsck
982 2002-11-08 Theodore Ts'o <tytso@mit.edu>
984 * Release of E2fsprogs 1.31
986 2002-11-08 <tytso@snap.thunk.org>
988 * Makefile.in (check): Skip trying to compile test_byteswap

993 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
994 support when the MASTER_SB_ONLY flag is set. Some of
995 the descriptor blocks that should have been written out
996 were getting skipped.
998 2002-10-31 Theodore Ts'o <tytso@mit.edu>
1000 * Release of E2fsprogs 1.30
1002 2002-10-31 Theodore Ts'o <tytso@mit.edu>
1004 * ext2_fs.h: Add support for a new inode flag, which is to be used
1005 for indicating the top of directory hierarchies for the
1006 Orlov block allocator.
1008 * ismounted.c (check_mntent, check_mntent_file): Add better
1009 support for loopback-mounted filesystems. Check /etc/mtab
1010 if /proc/mounts doesn't turn up any mount flags, since
1011 /etc/mtab has the loopback image filename, instead of
1012 /dev/loop0. Also, check based on st_dev and st_ino, so
1013 that if a relative pathname or a pathnames using symbolic
1014 links are used, we can detect the the filesystem correctly
1015 in those cases. (Addresses Sourceforge bug #619119)
1017 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
1018 don't try the FDFLUSH ioctl that was required for floppies
1019 with older kernels. This avoids needless whining from the
1020 MD device driver. (Addresses Sourceforge bug #545832).
1022 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
1023 wrong group_block to ext2fs_descriptor_block_loc if we're
1024 using the backup superblock/block group descriptors.
1025 (ext2fs_descriptor_block_loc): If we're using the backup
1026 superblock descriptors, use the backup descriptor block in
1027 the next block group.
1029 2002-10-30 Theodore Ts'o <tytso@mit.edu>
1031 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
1032 table so that it buts up against the bitmap blocks, to
1033 avoid block fragmentation.
1035 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
1036 bug; only allocate group descriptor blocks up to
1039 2002-10-25 Theodore Ts'o <tytso@mit.edu>
1041 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
1042 know when a filesystem was created. (Sometimes this can
1045 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
1047 2002-10-20 Theodore Ts'o <tytso@valinux.com>
1049 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
1050 the journal data mode.
1052 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
1053 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
1054 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
1055 the meta_blockgroup filesystem format.
1057 2002-10-15 <tytso@snap.thunk.org>
1059 * ext2_fs.h: Add new field in superblock for default mount options.
1061 2002-10-13 Theodore Ts'o <tytso@mit.edu>
1063 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
1066 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
1068 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1069 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
1070 because the bitmap is getting written to disk. Make
1071 ext2fs_swap_bitmap be a static function, since it's not
1072 intended to be exported.
1074 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
1076 2001-09-24 Theodore Tso <tytso@mit.edu>
1078 * Release of E2fsprogs 1.29
1080 2001-08-31 Theodore Tso <tytso@thunk.org>
1082 * Release of E2fsprogs 1.28
1084 2002-08-31 Theodore Ts'o <tytso@valinux.com>
1086 * dblist.c (ext2fs_dblist_sort): New function which allows the
1087 caller to pass in a special sort comparison function.
1089 2002-08-20 Theodore Ts'o <tytso@mit.edu>
1091 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
1092 failed to accurately characterize non-standard slow
1093 symlinks. (Which don't appear in practice on real-life
1094 systems, fortunately.)
1096 2002-08-17 Theodore Ts'o <tytso@mit.edu>
1098 * Makefile.in: Remove inode_io.o from the standard object files,
1099 and only build it if debugfs is enabled (it requires
1100 fileio.o, which is only built if --disable-debugfs isn't
1101 specified to configure).
1103 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
1104 incompatible way so that it is no longer
1105 endian-dependent. Add the TEA hash. Allow the seed
1106 parameter to be optional.
1108 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
1109 These features are all now in the HALF_MD4 hash. Add
1110 definition for EXT2_HASH_TEA.
1112 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
1113 a pointer instead of an array.
1115 2002-08-16 Theodore Ts'o <tytso@mit.edu>
1117 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
1119 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
1120 the number of data blocks used by an inode exclusive of
1123 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
1124 adjusts the reference count in an extended attribute block.
1126 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
1127 correctly deal with extended attribute blocks in symbolic
1130 2002-08-13 <tytso@snap.thunk.org>
1132 * Makefile.in: Move dupfs.o and test_io.o from the
1133 needed-by-debugfs object list to the needed-by-resizer
1134 object list. Fixes compile problem if the system is built
1135 with only --disable-debugfs.
1137 2002-07-29 Theodore Ts'o <tytso@mit.edu>
1139 * link.c (ext2fs_link): When adding a new link to a directory,
1140 clear the HTREE bit.
1142 2002-07-23 Theodore Ts'o <tytso@mit.edu>
1144 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
1145 calculations for names > 32 characters to be completely
1146 bogus. Changed MD4 calculation to match what is currently
1147 being used in the CVS gkernel tree.
1149 2002-07-19 Theodore Ts'o <tytso@mit.edu>
1151 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
1152 superblock definition.
1154 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
1155 create a set of u32_list functions.
1157 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
1158 since that's required by the directory indexing code.
1160 2002-07-14 Theodore Ts'o <tytso@mit.edu>
1162 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
1163 using a C++ reserved word.
1165 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
1166 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
1167 old version of glibc (built against 2.2 headers) will
1168 interact badly with the workaround to actually cause more
1169 problems. I hate it when the glibc folks think they're
1170 being smarter than the kernel....
1172 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
1174 * ext2_fs.h: Add superblock field for reserved group descriptors.
1176 2002-06-28 Theodore Ts'o <tytso@mit.edu>
1178 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
1179 ext2fs_cpu_to_{l,b}e{32,16}
1181 2002-06-27 Theodore Ts'o <tytso@mit.edu>
1183 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
1184 Add appropriate fallbacks in this case.
1186 2002-06-26 Theodore Ts'o <tytso@mit.edu>
1188 * dirhash.c (ext2fs_dirhash): Change function signature to support
1189 a hash seed, and to return the minor hash (for 64-bit hash
1190 support). Add support for the half MD4, half MD4 with
1191 seed, and half MD4 with seed and 64 bits.
1193 2002-06-15 Theodore Ts'o <tytso@mit.edu>
1195 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
1197 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
1199 * ext2_fs.h: Add macros for maximum block/inode counts:
1200 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
1201 and EXT2_MAX_INODES_PER_GROUP.
1203 * openfs.c (ext2fs_open): Check that the number of blocks in a group
1204 is less than 2^16, otherwise we need an INCOMPAT flag (not
1205 in existence yet, if ever) to open such a filesystem.
1207 * initialize.c (ext2fs_initialize): Limit the number of blocks and
1208 inodes in a group to less than 2^16.
1210 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
1212 * ext2_fs.h: Further minor cleanups of the header. Consolidate
1213 some checks for __KERNEL__ into one place.
1215 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
1217 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
1218 the EXT2_SB() macro instead. Remove kernel function
1219 prototypes also. This matches the 2.5 kernel, and
1220 is also cleaner for other reasons. Whitespace cleanup.
1222 2002-05-21 Theodore Ts'o <tytso@mit.edu>
1224 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
1226 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
1228 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
1230 * initialize.c (ext2fs_initialize): Remove assumption that
1231 blocksizes are always <= 4k.
1233 2002-05-11 Theodore Ts'o <tytso@mit.edu>
1235 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
1236 silently if inode pointer is NULL (and ext2fs_bmap is
1237 expected to read the inode itself).
1239 2002-04-27 Theodore Ts'o <tytso@mit.edu>
1241 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
1242 file we are checking is a block device file before looking
1243 at st_rdev, since it's not valid for normal files.
1244 (is_swap_device): Move so that it is outside the
1245 HAVE_MNTENT_H, so that it is always built.
1247 2002-03-11 Theodore Tso <tytso@mit.edu>
1249 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
1250 functions which take an extra flags argument. The flag
1251 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
1252 field is byte swampped on big-endian machines, since in
1253 the V2 structure, name_len is a char field which is
1254 doesn't need to be byte swapped --- except if an
1255 old-style kernel had byte-swapped the name_len field
1256 as part of the V1 structure.
1258 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
1260 * dirhash.c (ext2fs_dirhash): New function which calculates the
1261 hash for a filename in an indexed directory.
1263 2002-03-08 Theodore Tso <tytso@mit.edu>
1265 * Release of E2fsprogs 1.27
1267 2002-03-07 Theodore Tso <tytso@mit.edu>
1269 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
1271 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
1272 tst_byteswap.c: Fix gcc -Wall complaints
1274 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
1275 (From Philipp Thomas <pthomas@suse.de>)
1277 2002-02-25 Theodore Tso <tytso@mit.edu>
1279 * ext2_fs.h: Add structure definitions for the directory indexing
1282 2002-02-23 Theodore Tso <tytso@mit.edu>
1284 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
1285 it doesn't break things on mis32, sparc32, and alpha
1288 2002-02-21 Theodore Tso <tytso@mit.edu>
1290 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
1291 we were missing an fclose().
1293 2002-02-20 Theodore Tso <tytso@mit.edu>
1295 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
1296 abstraction interface which exports an ext2 inode.
1298 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
1299 as a public interface. Change void * to const void * in
1300 ext2fs_file_write's interface.
1302 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
1303 conditional; save a few bytes.
1305 2002-02-12 Theodore Tso <tytso@mit.edu>
1307 * Makefile.in (tst_badblocks): Add some extra .o files when
1308 linking the debugging program tst_badblocks which are
1309 needed if we aren't compiling with inline functions enable.
1311 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
1312 define away __inline__ since it may not be supported.
1314 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
1315 stripped down jbd_debug that doesn't use variadic
1316 arguments. This will cause warnings under AIX, but things
1319 2002-02-03 Theodore Tso <tytso@thunk.org>
1321 * Release of E2fsprogs 1.26
1323 2002-02-03 Theodore Tso <tytso@mit.edu>
1325 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
1326 so that the number of directories in use is adjusted
1329 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
1330 which optionally will modify the number of directories
1333 2002-01-03 Theodore Tso <tytso@mit.edu>
1335 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
1336 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
1337 which will return deleted directory entries.
1338 ext2fs_dir_iterate2 takes a new callback function which
1339 is identical with the one used by
1340 ext2fs_dblist_dir_iterate(). If the directory entry is
1341 deleted, the callback function will be called with the
1342 entry paraemter set to DIRENT_DELETED_FILE.
1344 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
1345 ext2fs_block_alloc_stats): New functions which update
1346 block/inode allocation statistics in the bitmaps, block
1347 group descriptors, and superblock.
1349 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
1350 expanddir.c (expand_dir_proc), bb_inode.c
1351 (clear_bad_block_proc, set_bad_block_proc,
1352 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
1353 Update to use new block/inode allocation statistics.
1355 2001-12-24 Theodore Tso <tytso@mit.edu>
1357 * ismounted.c (is_swap_device): New function used by
1358 ext2fs_check_if_mounted and ext2fs_check_mount_point which
1359 determines whether or not the specified device is a swap
1360 device by using /proc/swaps. More bulletproofing for
1361 idiotic/careless system administrators!
1363 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
1364 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
1365 field to struct_ext2_filsys, umask. This field is
1366 initialize to 022, and affects ext2fs_mkdir in the obvious
1367 way. (In the future umask should also affect new file
1368 creation routines, but the fileio functions don't
1369 currently support this yes.)
1371 * ismounted.c (check_mntent_file): Stat all of the entries in
1372 /etc/mtab and/or /proc/mounts in order to catch dim-witted
1373 system administrators who might have created alias
1376 2001-12-23 Theodore Tso <tytso@mit.edu>
1378 * Makefile.in, jfs_user.h: Move linux/jbd.h to
1379 ext2fs/kernel-jbd.h, to avoid using the system header
1380 file version of hbd.h when using diet glibc (since it
1381 forcibly adds /usr/include to the beginning of the
1382 include search path.)
1384 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
1385 include/linux directory.
1387 2001-12-16 Theodore Tso <tytso@mit.edu>
1389 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
1390 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
1391 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
1393 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
1396 2001-12-03 Theodore Tso <tytso@mit.edu>
1398 * unix_io.c (unix_open): Make sure the ulimit workaround works
1399 regardless of the version of glibc which is used to
1402 2001-11-26 Theodore Tso <tytso@mit.edu>
1404 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
1405 trying to unset the filesize limit if at all possible,
1406 if a block device is getting opened. (The filesize limit
1407 shouldn't be applied against writes to a block device, but
1408 starting in 2.4.10, the kernel is doing this.)
1410 2001-11-05 Theodore Tso <tytso@mit.edu>
1412 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
1413 file on adding a journal to an already-mounted filesystem,
1414 try to clear the ext2 file attributes on an already
1415 existing .journal file so that we don't fail if on a
1416 partially added journal to the filesystem.
1418 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
1419 which signals that a particular inode should not have the
1420 last bits of data (the "tail") be merged with another
1421 file. This is necessary to keep LILO happy.
1423 2001-09-20 Theodore Tso <tytso@thunk.org>
1425 * Release of E2fsprogs 1.25
1427 2001-09-16 Theodore Tso <tytso@mit.edu>
1429 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
1430 which was breaking the build on the Hurd. (Addresses
1431 Debian bug #112414).
1433 2001-09-13 Theodore Ts'o <tytso@mit.edu>
1435 * ismounted.c (check_mntent_file): We now validate the entry in
1436 /etc/mtab to make sure the filesystem is really mounted,
1437 since some broken distributions (read: Slackware) have
1438 buggy boot scripts that don't initialize /etc/mtab before
1439 checking non-root filesystems. (Slackware also doesn't
1440 check the root filesystem separately, and reboot if the
1441 root filesystem had changes applied to it, which is
1442 dangerous and broken.)
1444 2001-09-02 Theodore Tso <tytso@thunk.org>
1446 * Release of E2fsprogs 1.24a
1448 2001-08-30 Theodore Tso <tytso@thunk.org>
1450 * Release of E2fsprogs 1.24
1452 2001-08-30 Theodore Tso <tytso@valinux.com>
1454 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
1455 changes, since the ioctl number has been reused by another
1458 2001-08-15 Theodore Tso <tytso@valinux.com>
1460 * Release of E2fsprogs 1.23
1462 2001-08-05 Theodore Tso <tytso@valinux.com>
1464 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
1465 version of the bitmap test routines to speed up these
1466 routines. (At some point I may want to make these
1467 routines use the find_first_bit functions, but that will
1468 add a lot of complexity since it means that these
1469 functions will have to break the bitmap abstraction
1470 boundary. It's not clear it's worth it.)
1472 * mkjournal.c (mkjournal_proc): Remember the last block allocated
1473 to speed up ext2fs_new_block().
1475 2001-07-29 Theodore Tso <tytso@valinux.com>
1477 * finddev.c (scan_dir): Fix memory leak; we weren't calling
1478 closedir() when exiting the function in all cases.
1480 2001-07-27 Theodore Tso <tytso@valinux.com>
1482 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
1483 block usable in the journal for external journals to be 2
1484 or 3, depending on the blocksize, so that the existing
1485 kernel code does the right thing.
1487 * getsize.c (ext2fs_get_device_size): Add support for the
1488 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
1489 from Ben LaHaise, but it's likely this interface won't
1492 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1493 when writing the journal superblock, too. (Oops! Needed
1494 to make 1k filesystems with external journal to work.)
1496 2001-07-26 Theodore Tso <tytso@valinux.com>
1498 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1499 to find the journal superblock if the blocksize is 1024.
1501 2001-07-21 Theodore Tso <tytso@valinux.com>
1503 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
1505 2001-07-20 Theodore Tso <tytso@valinux.com>
1507 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
1508 attribute block, set the filesystem changed bit.
1510 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1511 Comment out these functions since we're not using them.
1513 2001-07-10 Theodore Tso <tytso@valinux.com>
1515 * closefs.c (write_primary_superblock): After writing changes to
1516 the primary superblock, update the original superblock
1517 copy so we don't have to re-write those changes in the
1519 (ext2fs_flush): Clear the superblock dirty flag after
1520 we've flushed out changes to disk.
1522 2001-07-07 Theodore Tso <tytso@valinux.com>
1524 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
1525 to avoid register conflicts when compiling in PIC mode.
1527 2001-07-04 Theodore Tso <tytso@valinux.com>
1529 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1530 Add new functions (C and in i386 assembler) which quickly
1531 find bits set in a bitmask.
1533 2001-06-23 Theodore Tso <tytso@valinux.com>
1535 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
1536 ext2_ext_attr.h and ext_attr.c for extended attributes
1539 * Release of E2fsprogs 1.22
1541 2001-06-22 Theodore Tso <tytso@valinux.com>
1543 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
1544 descriptor so that adding a journal to a mounted
1545 filesystem doesn't die. (Fixes a bug accidentally
1546 introduced in e2fsprogs 1.21.)
1548 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
1549 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
1550 fchflags without defining UF_NODUMP. (Addresses Debian
1553 * flushb.c: Use platform independent method of defining the
1554 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
1555 since on newer glibc's BLKFLSBUF is defined there.
1557 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
1558 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
1559 to support byte swapping even if we don't support the
1560 conversion functions. (Fixes Debian bug #101686).
1562 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
1563 since the byte-swapping code all assumes the
1564 ext2_dir_entry structure. (It's a question of whether or
1565 not name_len should be byte-swapped or not, and whether
1566 it's a 16 bit or 8 bit field.)
1568 2001-06-15 Theodore Tso <tytso@valinux.com>
1570 * Release of E2fsprogs 1.21
1572 2001-06-15 Theodore Tso <tytso@valinux.com>
1574 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
1575 file which is generated and is therefore found in the
1576 build directory, not source directory.
1578 * ismounted.c (check_mntent_file): Use a test file in / to check
1579 to see if the root filesystem is mounted read-only. This
1580 protects against the case where /etc might not be on /, as
1581 well as the case where /etc/mtab doesn't exist. (Both are
1582 should-never happen scenarios, but you never know...)
1584 2001-06-14 Theodore Tso <tytso@valinux.com>
1586 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
1587 Remove unneeded #pragma argsused, since the arguments are
1590 2001-06-13 Theodore Tso <tytso@valinux.com>
1592 * ext2_types.h.in: If linux/types.h has been defined, then don't
1593 try to redefine the typedefs.
1595 * Makefile.in (HFILES): Add ext2_types.h to the list of files
1596 which should be installed.
1598 * ismounted.c (check_mntent_file): Work around GNU hurd brain
1599 damage. Addresses Debian bug #100304.
1601 * Makefile.in: Limit some .o files from being included into the
1602 library if --disable-debugfs, --disable-swapfs,
1603 --disable-imager, or --disable-resizer are used.
1605 2001-06-12 Theodore Tso <tytso@valinux.com>
1607 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
1608 function, and use the ext2fs_badblocks_* functions
1611 2001-06-11 Theodore Tso <tytso@valinux.com>
1613 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
1614 ext2fs_mark_generic_bitmap and
1615 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
1616 functions. (This saves space and doesn't significantly
1617 change the speed of e2fsck on a P-III.)
1619 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
1620 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
1621 include the byte-swapping logic if ENABLE_SWAPFS is turned
1622 on or if we're on a big-endian machine.
1624 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
1625 set EXT2_FLAG_SWAP_BYTES, instead of using
1628 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
1629 autoconf to determine whether or not return
1630 EXT2_FLAG_SWAP_BYTES.
1632 2001-06-10 Theodore Tso <tytso@valinux.com>
1634 * Makefile.in: Remove the dependence on the libe2p library.
1636 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
1637 with direct usage of the ioctl/fchflags so that we don't
1638 have to depend on the libe2p library.
1640 2001-06-08 Theodore Tso <tytso@valinux.com>
1642 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
1643 when trying to find a 32-bit wide type.
1645 * icount.c (insert_icount_el): Fix the code used to estimate the
1646 size of the new icount array to be more intelligent, to
1647 avoid reallocating the array too many times. Thanks to
1648 Enrique Perez-Terron for pointing this out.
1650 2001-06-02 Theodore Tso <tytso@valinux.com>
1652 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
1653 for a symlink to determine whether it is a fast symlink.
1655 2001-06-01 Theodore Tso <tytso@valinux.com>
1657 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
1658 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
1660 2001-05-25 Theodore Tso <tytso@valinux.com>
1662 * Release of E2fsprogs 1.20
1664 2001-05-25 Theodore Tso <tytso@valinux.com>
1666 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
1667 some to clean up Andreas's patches. Use strncpy instead
1668 of strcpy to save the root's mountpoint. Clean up #ifdef
1669 structure. Remove uneeded variable in testing/debug driver.
1671 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
1673 * ismounted.c: Add check for root device which doesn't depend on
1674 /etc/fstab or /proc/mounts to be correct. Don't call
1675 endmntent() before we are done with mnt struct.
1677 2001-05-23 Theodore Tso <tytso@valinux.com>
1679 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
1682 2001-05-21 Theodore Tso <tytso@valinux.com>
1684 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
1685 make room for pre-existing usage of
1686 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
1687 the same codepoint as EXT2_BTREE_FL.
1689 2001-05-20 Theodore Tso <tytso@valinux.com>
1691 * ext2fs.h: #include <> instead of "" for ext2fs and et header
1692 files, since they will be installed in /usr/include
1694 2001-05-14 Theodore Tso <tytso@valinux.com>
1696 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
1697 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1698 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

1707 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
1708 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
1709 Adjust all files in this directroy to include this file.
1711 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
1714 2001-05-05 Theodore Tso <tytso@valinux.com>
1716 * fileio.c (ext2fs_file_read): Factored out common code and
1717 cleaned up function. Fixed a bug where if there was an
1718 error reading from the disk, the number of bytes read
1719 wasn't reliably set. (Fixes Debian bug #79163)
1720 (ext2fs_file_write): Factored out common code and made
1721 function more efficient; if writing a full block, don't
1722 bother to do a read-modify-write cycle.
1724 2001-05-04 Theodore Tso <tytso@valinux.com>
1726 * dirblock.c (ext2fs_read_dir_block): Check for an directory
1727 record length which isn't a multiple four, and treat that
1728 as an invalid. Scan the directory and return an error
1729 (EXT2_ET_DIR_CORRUPTED) if the directory records are
1731 (ext2fs_write_dir_block): If while byte-swapping the
1732 directory block, if there's an error, abort and return
1733 EXT2_ET_DIR_CORRUPTED.
1735 2001-05-02 Theodore Tso <tytso@valinux.com>
1737 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
1738 image_header field in the ext2_filsys structure
1740 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
1741 * inode.c (ext2fs_read_inode):
1742 * rw_bitmaps.c (read_bitmaps):
1743 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
1745 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
1746 sure the full bitmap is saved.
1748 2001-05-01 Theodore Tso <tytso@valinux.com>
1750 * e2image.h (struct ext2_image_hdr): Add space for the device name
1751 in the image header.
1753 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
1754 make sure the rec_len is a multiple of 4, to prevent
1755 bus-errors on architectures which care about mis-aligned
1758 2001-04-25 Theodore Tso <tytso@valinux.com>
1760 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
1761 query the device sizes using the BLKGETSIZE ioctl.
1763 2001-04-16 Theodore Tso <tytso@valinux.com>
1765 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
1766 before checking /etc/mtab. The EXT2_MF_READONLY flag is
1767 now set from the /etc/mtab options field for all
1768 filesystems, not just the root filesystem. Add debugging
1769 code to make it easier to test ext2fs_check_if_mounted().
1771 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
1772 check; return an error if there's an attempt to create a
1773 journal less than 1024 filesystem blocks.
1775 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
1776 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
1778 2001-02-20 Theodore Tso <tytso@valinux.com>
1780 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
1783 * tst_byteswap.c: New function to test the byteswap functions.
1784 Add to regression test suite.
1786 2001-02-08 Theodore Tso <tytso@valinux.com>
1788 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
1790 2001-02-07 Theodore Tso <tytso@valinux.com>
1792 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
1793 of s_first for external devices to always be 1, since
1794 jsb->s_first is always relative to the start of the
1795 journal superblock. Use htonl(1) when setting s_nr_users.
1797 2001-01-17 Theodore Ts'o <tytso@valinux.com>
1799 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
1800 device number of the filesystem (instead of the journal)
1801 was being dropped into s_journal_dev.
1803 2001-01-15 Theodore Ts'o <tytso@valinux.com>
1805 * initialize.c (ext2fs_initialize): Add support for initializing
1806 the ext2 superblock for external journal devices. This
1807 basically means we don't bother to allocate any block
1810 * openfs.c (ext2fs_open): Only open external journal devices if
1811 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
1812 ext2fs_open. When opening such devices, don't try to read
1813 the block group descriptors, since they're not there.
1815 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
1817 * mkjournal.c: Export a new function,
1818 ext2fs_create_journal_superblock(), which allocates and
1819 returns a buffer containing a journal superblock. This is
1820 needed by mke2fs to create an external journal. Rewrote
1821 ext2fs_add_journal_device() so that it no longer creates
1822 the external journal, but rather adds a filesystem to an
1823 existing external journal. It handles all of the UUID
1826 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
1827 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
1828 Changed function prototype for ext2fs_add_journal_device().
1830 2001-01-14 Theodore Ts'o <tytso@valinux.com>
1832 * closefs.c (ext2fs_flush): Don't write out anything beyond the
1833 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
1836 2001-01-12 Theodore Ts'o <tytso@valinux.com>
1838 * imager.c: Fix gcc -Wall complaints and a series of bugs where
1839 retval wasn't set correctly. (Thanks to Andreas Dilger
1840 for pointing this out.)
1842 2001-01-11 <tytso@snap.thunk.org>
1844 * flushb.c (ext2fs_sync_device): New function which centralizes
1845 all of the places which might try to use the BLKFLSBUF
1846 or FDFLUSH ioctls (and usually failing to define them
1847 since the system header files don't usually do this for
1848 us, and we're trying to avoid usage of kernel include
1851 2001-01-10 <tytso@snap.thunk.org>
1853 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
1854 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
1855 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
1856 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
1857 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
1858 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
1859 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
1860 ext2_ino_t, to protect applications that attempt to
1861 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
1862 changes ino_t(!?). So we use ext2_ino_t to avoid an
1863 unexpected ABI change.
1865 2001-01-05 <tytso@snap.thunk.org>
1867 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
1868 we may overrun allocated memory in case of a corrupted
1869 filesystem (or an e2fsck test case :-) when byte-swapping
1870 the directory block.
1872 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
1874 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
1875 complaints including a missing return 0 at the end of
1876 ext2fs_add_journal_device.
1878 2001-01-03 <tytso@snap.thunk.org>
1880 * Makefile.in: Link in libe2p when creating libext2fs as a shared
1881 library, since mkjournal.c now references fsetflags().
1883 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
1884 Dilger's changes (with fixups) to allow on-line creation
1887 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
1888 EXT2_FLAG_SUPER_ONLY, which the close routines to only
1889 update the superblock, and not the group descriptors.
1891 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
1893 * ismounted.c: add ext2fs_check_mount_point() function, which will
1894 optionally return the mount point of a device if mounted
1896 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
1898 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
1899 ext2fs_add_journal_inode()
1901 2001-01-01 <tytso@snap.thunk.org>
1903 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
1904 source (but not binary) compatibility of some users of the
1905 ext2 library. They should just simply do a global search
1906 and replace of struct ext2fs_sb with struct
1907 ext2_super_block, and use their own private copy of
1908 ext2_fs.h if they aren't already.
1910 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
1911 Replace use of ext2fs_sb with ext2_super_block.
1913 2000-12-31 <tytso@snap.thunk.org>
1915 * ext2fs.h: Cleaned up header file by removing definitions of
1916 feature flags that might not have been defined in older
1917 ext2 header files. Now that we're using our own
1918 include/linux/ext2fs.h header file, this can never happen.
1920 * jfs_dat.h: Removed old header file which is no longer needed.
1922 2000-12-13 Theodore Ts'o <tytso@valinux.com>
1924 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
1925 by Andreas Dilger to update the filesystem revision to
1928 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
1931 2000-12-09 <tytso@snap.thunk.org>
1933 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
1934 ext2fs_add_journal_device): Add a new argument to the APIs
1935 of these function, which is a flags word. This is used to
1936 allow the creation of a V1 superblock for those folks who
1937 are using ext3 0.3b in production. Note, the user-land
1938 interface for getting at this flag won't be documented, as
1939 the V1 superblock is deprecated.
1941 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
1942 which creates a V2 superblock instead of a V1 superblock.
1944 2000-11-21 <tytso@snap.thunk.org>
1946 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
1947 out by Andreas Dilger.
1949 2000-11-05 <tytso@snap.thunk.org>
1951 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
1952 ext2_fs.h, Makefile.in: New file that has routines that
1953 save ext2fs metadata to a file.
1955 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
1957 * e2image.h: New file which defines the file format for the ext2
1958 image file. (Saved copy of ext2 metadata to a file as a
1959 saving throw against worst-case damage.)
1961 2000-11-01 <tytso@snap.thunk.org>
1963 * inode.c (ext2fs_flush_icache): Add new function
1964 ext2fs_flush_icache() which flushes the internal inode
1965 cache. Applications which modify the inode table blocks
1966 directly must call this function.
1968 2000-10-26 <tytso@snap.thunk.org>
1970 * mkjournal.c: Add #include of netinet/in.h, since Solaris
1971 requires it for ntohl().
1973 * ext2_io.h (io_channel_write_byte): Add new interface to allow
1974 callers to write specific byte ranges. This is an
1975 optional interface, which not all IO channels may
1978 * unix_io.c (unix_write_byte):
1979 * test_io.c (test_write_byte): Add implementation of the
1980 write_byte function.
1982 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
1983 function which writes the primary superblock. If the IO
1984 channel supports writing raw bytes directly, only fields
1985 which were modified are written to the disk. This makes
1986 it safe(r) to use utilities like tune2fs on a mounted
1989 * freefs.c (ext2fs_free): Free the original superblock if it is
1992 * openfs.c (ext2fs_open): Store a copy of the original superblock
1995 * ext2fs.h: Add a field to store the original superblock in the
1996 ext2 context structure.
1998 2000-10-24 <tytso@snap.thunk.org>
2000 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
2001 don't need to use llseek).
2003 2000-10-24 <tytso@valinux.com>
2005 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
2006 creating an ext3 journal on a filesystem.
2008 2000-08-21 <tytso@valinux.com>
2010 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
2012 2000-08-22 <tytso@valinux.com>
2014 * unix_io.c: Make massive changes to support a multiple block
2015 writethrough cacheing.
2017 * ext2_io.h: Added flags field to the io_channel structure.
2019 2000-08-19 <tytso@valinux.com>
2021 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
2022 provides the function ext2fs_find_block_device(). This
2023 function returns the pathname to a block device, given its
2026 2000-07-13 <tytso@valinux.com>
2028 * Release of E2fsprogs 1.19
2030 2000-07-07 Theodore Ts'o <tytso@valinux.com>
2032 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
2033 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
2034 list of filesystem flags supported by the library.
2036 2000-07-04 Theodore Ts'o <tytso@valinux.com>
2038 * ext2fs.h: Update to include latest journalling additions to the
2041 * dll/jump.funcs: Add new jumptable entries for
2042 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
2043 ext2fs_badblocks_equal.
2045 * tst_badblocks.c: Update test program to test
2046 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
2048 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
2049 writes out bad blocks list to a file.
2051 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
2052 changes the callback function to take two additional
2053 arguments; a private blind pointer supplied by the caller,
2054 and pointer to a char * containing a pointer to the
2057 * badblocks.c (ext2fs_badblocks_equal): Add new function which
2058 returns true if two badblocks list are equal.
2060 * Makefile.in: Remove explicit link of -lc in the shared library.
2061 (It shouldn't be necessary, and is harmful in some cases).
2063 2000-06-10 Theodore Ts'o <tytso@valinux.com>
2065 * getsize.c (main): Add debugging code under #ifdef DEBUG
2067 2000-05-27 Theodore Ts'o <tytso@valinux.com>
2069 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
2070 earlier, so that if there's an error reading it, we can
2071 more cleanly back out of the operation.
2073 2000-05-25 <tytso@snap.thunk.org>
2075 * getsize.c (ext2fs_get_device_size): Use open64() instead of
2076 open() if it exists. Under linux, manually define the
2077 ioctl for BLKGETSIZE if it isn't already defined and it's
2080 * unix_io.c (unix_open): Use open64() instead of open() if it
2083 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
2084 available (and prototypes are defined) use it in
2085 preference to llseek.
2087 * Makefile: Add hack dependency rule so that parallel makes work
2090 2000-05-18 Theodore Ts'o <tytso@valinux.com>
2092 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
2094 2000-04-03 Theodore Ts'o <tytso@valinux.com>
2096 * block.c: Readibility tweak in conditionals involving
2099 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
2100 how to define __s64 and __u64. Turn off "compression is
2101 experimental" warning if the cpp macro
2102 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
2104 2000-02-11 <tytso@snap.thunk.org>
2106 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
2107 Conditionally include Compression as a supported type if
2108 ENABLE_COMPRESSION (via --enable-compression) is turned on.
2110 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
2112 2000-02-08 <tytso@snap.thunk.org>
2114 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
2115 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2116 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
2117 Change to return the previous state of the bit that is
2118 being marked or unmarked. For speed optimization.
2120 2000-02-02 Theodore Ts'o <tytso@valinux.com>
2122 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
2124 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
2125 needed any more; we know it will always be i_generation.
2126 Add support for swapping the high bits of the uid and gid.
2128 1999-11-19 <tytso@valinux.com>
2130 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
2131 counts if the link was successful. Patch suggested by
2134 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
2135 the source directory.
2137 1999-11-10 <tytso@valinux.com>
2139 * Release of E2fsprogs 1.18
2141 1999-11-08 <tytso@valinux.com>
2143 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
2144 since ext2fs_badblocks_list_free was moved to freefs.c.
2146 * tst_badblocks.c: Use the newer badblocks API names. Add
2147 duplicate blocks to the test inputs to test dealing with
2148 adding blocks which are already in the badblocks list.
2150 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
2151 of the list, use a shortcut O(1) operations instead of an
2152 O(n) operation. (Idea suggested by David Beattie.)
2154 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
2155 of badblocks_list_free(), to save a procedure call.
2157 1999-10-26 <tytso@valinux.com>
2159 * Release of E2fsprogs 1.17
2161 1999-10-26 <tytso@valinux.com>
2163 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
2164 seem to handle ~0UL the same way as they used to.
2166 1999-10-25 <tytso@valinux.com>
2168 * nt_io.c (_OpenNtName): Open the device using
2169 FILE_SYNCHRONOUS_IO_NONALERT instead of

2172 the drive but do not dismount it.
2174 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
2177 1999-10-22 <tytso@valinux.com>

2181 1999-10-22 <tytso@valinux.com>
2183 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
2185 * link.c (ext2fs_link): This call now uses the low three bits of
2186 the flags parameter to pass the directory filetype
2187 information; it will set the directory entry FILETYPE
2188 information if the filesystem supports it.
2190 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
2191 option is set, then create the '.' and '..' entries with
2192 the filetype set to EXT2_FT_DIR.
2194 1999-09-24 <tytso@valinux.com>
2196 * nt_io.c: New file which supports I/O under Windows NT.
2198 1999-09-07 <tytso@valinux.com>
2200 * ext2fs.h: Add new fields for journalling and define new
2201 feature bits used by newer filesystems: IMAGIC_INODES,
2202 HAS_JOURNAL, RECOVER.
2204 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
2205 we update the inode block count and size files so that the
2206 block count field is updated correctly when we create an
2209 1999-07-18 Theodore Ts'o <tytso@valinux.com>
2211 * Release of E2fsprogs 1.15
2213 1999-06-23 <tytso@valinux.com>
2215 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
2216 kernels that use i_generation instead of i_version. Patch
2217 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
2219 1999-06-21 <tytso@valinux.com>
2221 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
2222 directory entry before calling the callback function.
2223 This should prevent some core dumps of insufficiently
2224 paranoid callback functions.
2226 1999-05-29 <tytso@rsts-11.mit.edu>
2228 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
2230 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
2231 that we don't handle writing yet (we do). Fixed bug where
2232 we weren't allocating a big enough buffer for ext2_bmap.
2234 1999-05-03 <tytso@rsts-11.mit.edu>
2236 * openfs.c (ext2fs_open): Check to make sure that the number of
2237 blocks per group is not zero --- if so, it must be a bad
2240 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2242 * Release of E2fsprogs 1.14
2244 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
2246 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
2247 the inode number is zero; if it's zero, return
2248 EXT2_ET_BAD_INODE_NUM.
2250 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2252 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
2253 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
2256 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
2258 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
2259 non-Linux case to use EINVAL by default, unless it isn't
2260 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
2263 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
2265 * Release of E2fsprogs 1.13
2267 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
2269 * Makefile.in: Updated dependencies.
2271 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
2273 * initialize.c (ext2fs_initialize): Make sure that we allocate
2274 enough inodes so that we can make a valid filesystem.
2276 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
2278 * rw_bitmaps.c: Fixed signed/unsigned warnings.
2280 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
2281 function declaration.
2283 * dblist.c (make_dblist): Add safety check in case the dblist
2284 pointer passed in is null (in which case, assign it to
2285 fs->dblist). Fixed some signed/unsigned warnings.
2287 * bmap.c: Make addr_per_block be of type blk_t to avoid
2288 signed/unsigned warnings.
2290 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
2291 function declaration.
2293 * get_pathname.c (get_pathname_proc): Use return value from
2294 ext2fs_get_mem, instead of checking if &gp->name is
2297 * dir_iterate.c (ext2fs_process_dir_block):
2298 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
2299 from the function declaration.
2301 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
2302 return the error directly instead of jumping to the
2303 cleanup routine, since we don't need to do any cleanup.
2305 * alloc_table.c (ext2fs_allocate_group_table): Make this
2306 function take a dgrp_t for its group argument.
2308 * ext2fs.h: Make dgrp_t an __u32 type, and make
2309 fs->desc_group_count be of type dgrp_t.
2311 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
2313 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
2314 than 10 blocks when we need to expand the size of the
2317 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2319 * Release of E2fsprogs 1.12
2321 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2323 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
2324 appropriate for all of the block group copies, so that
2325 it's clear where the beginning of the filesystem is on the
2326 disk. (For when the partition table gets scrod.)
2328 * ext2fs.h: Change the name of the feature from
2329 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
2330 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
2332 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
2334 * inode.c (get_next_blockgroup): Fix bug where if
2335 get_next_blockgroup() is called early because of a missing
2336 inode table in a block group, the current_inode counter
2337 wasn't incremented correctly.
2339 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
2341 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
2342 against a completely trashed bad block inode.
2344 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
2346 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
2347 the stride length hits a bad value, we retry the block
2348 allocation starting at the beginning of the block group.
2350 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
2351 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
2352 e2_blkcnt_t to avoid collision with LFS API.
2354 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
2356 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
2357 way that avoids overflows on disk sizes greater than 4GB.
2359 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
2361 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
2362 return type for comparison functions for qsort.
2364 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
2367 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
2369 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
2372 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
2373 evade a potential problem with glibc's header files trying
2374 to spike out linux/types.h.
2376 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
2377 include the old size of the memory, which is needed for
2378 some braindamaged memory allocation systems that don't
2381 * badblocks.c (ext2fs_badblocks_list_add):
2382 bb_inode.c (clear_bad_block_proc):

2385 irel_ma.c (ima_put):
2386 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
2387 pass the old size of the memory to be resized to
2388 ext2fs_resize_mem().
2390 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2392 * Makefile.in: Change to use new installation directory variables
2393 convention. Fix uninstall rules to take $(DESTDIR) into
2396 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
2398 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
2399 with 32 bit longs, then we need to manually define __s64
2400 and __u64, since the current kernel header files don't
2401 define these if __STRICT_ANSI__ is defined. This is a
2402 problem if we are compiling with full GCC warnings, since
2403 we do need 64 bit support.
2405 * Makefile.in (OBJS): Remove bmove.o from files to be built,
2406 since we're not using ext2fs_move_blocks() and there
2407 is some question as to its usefulness in its current
2410 * bmap.c (block_bmap): Remove unused function.
2412 * bmove.c (process_block): Fix -Wall warning.
2414 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
2416 * block.c (ext2fs_block_iterate3): Make the ref_offset field
2417 contain the offset into the inode.i_blocks array when
2418 ref_block is zero. Since we haven't done a formal
2419 release of e2fsprogs since block_iterate2 was first
2420 introduced, I removed block_iterate2, and renamed
2421 block_iterate3 to be block_iterate2.
2423 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
2424 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
2425 use of block_iterate and block_iterate2 to
2426 block_iterate2 with the new prototype for the
2427 interator function. (using blkcnt_t forr blockcount)
2429 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
2431 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
2432 s_prealloc_blocks, s_prealloc_dir_blocks). Added
2433 conditional defines of new features COMPAT_DIR_PREALLOC,
2434 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
2435 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
2436 the library to declare that we support COMPAT_DIR_PREALLOC,
2437 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
2439 * fileio.c: Rename function ext2fs_file_llseek to be
2440 ext2fs_file_lseek, which is more accurate.
2442 * block.c: Add new function ext2fs_block_iterate3 which calls
2443 the iterator function with the blockcount argument of
2444 type blkcnt_t. This version of the function is
2445 allowed to handle large files; the other fucntions are
2448 * ext2fs.h: Add new type blkcnt_t
2450 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
2452 * block.c (ext2fs_block_iterate2): Fix bug where the block count
2453 field wasn't getting correctly incremented for sparse
2454 files when the indirect or doubly-indirect block
2455 specified in the inode was zero.
2457 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2459 * unlink.c (unlink_proc):
2460 * lookup.c (lookup_proc):
2461 * link.c (link_proc):
2462 * get_pathname.c (get_pathname_proc):
2463 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
2464 from dirent->name_len, so it can be used for other
2467 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
2468 and indicate that we have support for this incompatible

2473 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
2475 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>

2478 number of directories when the block group information is
2481 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
2483 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
2484 inode table is missing so that we catch the case where the
2485 first block group is missing.
2487 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
2490 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2492 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
2494 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
2496 * test_io.c (test_flush): Add a debugging printf when the flush
2499 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
2500 read in, return right away.
2502 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2504 * bitops.h: Don't try to do i386 inline asm functions if the
2507 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
2508 instead of linux/types.h, and e2_bitops.h instead of
2511 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
2514 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2516 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
2517 so that we don't need to call get_next_blockgroup() the
2518 first time around. Saves a bit of time, and prevents us
2519 from needing to assign -1 to current_group (which is an
2522 * icount.c (insert_icount_el): Cast the estimated number of inodes
2523 from a float to an ino_t.
2525 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

2562 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2564 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
2565 paranoid about validating the directory counts from the
2566 block group information.
2568 * all files: Don't include stdlib.h anymore; include it in
2569 ext2_fs.h, since that file requires stdlib.h
2571 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2573 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
2574 bitmap is loaded, and return an error if it is not.
2575 (expand_dir_proc): Only use ext2fs_write_dir_block when

2673 * llseek.c: Added missing semicolon to glibc fixup declaration of
2676 * bmove.c: Add #include of errno.h

2688 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2690 * io.h: Change the prototype of ext2fs_llseek() to use int's
2691 instead of unsigned int's.
2693 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
2694 to make life easer for GNU Libc 2.
2696 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
2697 filesystem has its bitmaps stored as 32-bit words with bit
2698 0 as the LSB of each word. Thus a bitmap with only bit 0
2699 set would be, as a string of bytes, 00 00 00 01 00 ... To
2700 cope with this, we byte-reverse each word of a bitmap if
2701 we have a big-endian filesystem, that is, if we are *not*
2702 byte-swapping other word-sized numbers.
2704 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

2768 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
2769 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
2771 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2773 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
2774 is zero, then return EXT2_IO_LLSEEK_FAILED.
2776 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
2778 * Release of E2fsprogs 1.11
2780 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2782 * dblist.c (ext2fs_dblist_count): Added new function which returns
2783 the number of directory blocks in dblist.
2785 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2787 * unix_io.c (unix_flush): Make the io_channel flush function do a
2788 fsync to flush the kernel buffers to disk.
2790 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2792 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
2793 current inode number wasn't being set by the
2794 goto_blockgroup function.
2796 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2798 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
2799 of blocks which need to be moved, and moves those blocks
2800 to another location in the filesystem.
2802 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
2803 bitmap, make sure all of the new parts of the bitmap are
2806 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2808 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
2809 wasn't being returned to the caller.
2811 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
2812 ext2fs_allocate_group_table() which sets the group tables
2813 for a particular block group. The relevant code was
2814 factored out of ext2fs_allocate_tables().
2816 * dblist.c (make_dblist): Adjust the initial size of the directory
2817 block list to be a bit more realistic (ten plus twice the
2818 number of directories in the filesystem).
2820 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2822 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
2823 ext2fs_badblocks_list_test would test the list (and exceed
2824 array boundaries) if there were no bad blocks on the bad
2825 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
2827 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2829 * Release of E2fsprogs version 1.10
2831 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2833 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
2834 inode and block bitmaps based on the RAID 0 stride
2835 parameter (which is passed by mke2fs).
2837 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
2838 mke2fs to communicate the stride length to
2839 ext2fs_allocate_tables()
2841 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2843 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
2844 systems. (We can't assume that the new filesystem types
2847 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2849 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
2850 allocate the inode and block bitmaps inside block group at
2853 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2855 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
2856 filesystem has no free blocks, ext2fs_new_block would loop
2859 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
2861 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
2862 free if refcount goes to zero.

2866 * ext2fsP.h: Added refcount to ext2_inode_cache
2868 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
2871 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
2872 badblocks structure.
2874 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2876 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
2878 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
2880 (unix_close, test_close): Decrement the refcount and only
2881 close the io_channel if the refcount goes to 0.
2883 * io.h: Add refcount to the io_channel structure. Add new macro
2884 interface io_channel_bumpcount() to bump the refcount.
2886 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2888 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
2889 cache in the filesystem handle, instead of the inode cache
2890 in a static variable.
2892 * freefs.c: Added static function to free the inode cache (called by
2895 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
2897 * ext2fs.h: Added pointer to the inode_cache structure.
2899 * block.c (block_iterate_ind, block_iterate_dind,
2900 block_iterate_tind): If there are holes in the indirect,
2901 doubly indirect, or triply indirect blocks, increment the
2902 block count field automatically.
2904 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2906 * Release of E2fsprogs version 1.09
2908 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2910 * version.c (ext2fs_parse_version_string): Check the passed in
2911 version string (instead of the hard-coded one).
2913 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
2914 greater filesystem size, clamp it to prevent allocating a
2915 block or inode bitmap beyond the filesystem.
2917 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
2918 overhead calculation was accidentally removed.
2920 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2922 * Release of E2fsprogs version 1.08
2924 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2926 * dblist.c (ext2fs_set_dir_block): New function which sets the
2927 block of a dblist entry, given the directory inode and
2930 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2932 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
2933 inode bitmaps at staggered locations across the block
2934 groups, to avoid concentrating the bitmaps on a small
2935 number of disks when using striped RAID arrays.
2937 * initialize.c (ext2fs_initialize): By default, choose the maximum
2938 possible number of blocks per group (based on the size of
2939 the bitmaps in the blocksize).
2941 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2943 * initialize.c (ext2fs_initialize): Add support for
2944 EXT2_COMPAT_SPARSE_SUPER feature.
2946 * closefs.c (ext2fs_bg_has_super): New function to determine
2947 whether or a particular block group should have a
2948 superblock and block group descriptor. Used for the
2949 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
2950 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
2951 or not the superblock should be written out for the block
2954 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
2955 for sparse duplicate superblocks.
2957 * version.c (ext2fs_get_library_version): New function which
2958 returns the library version.
2960 * version.c (ext2fs_parse_version_string): New function which
2961 parses a version string and returns a version number,
2962 so application programs can compare version numbers as
2965 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2967 * icount.c (ext2fs_create_icount): Change function so that it also
2968 takes a new argument which contains a "hint" icount
2969 structure. This "hint" icount allows the create function
2970 to set up the sorted list in advance. This reduces
2971 significantly the amount of data moving needed to insert
2972 these inodes into the list later.
2974 * icount.c (ext2fs_icount_validate): New function which validates
2975 that the icount structure's rep invariant.
2977 * icount.c (get_icount_el): Completely revamped implementation
2978 to subsume put_icount_el(). Put_icount_el() used to
2979 use an O(N) implementation to insert in the middle
2980 of the icount list. It now uses a O(ln N) to search
2981 for where the icount should be inserted, and then uses
2982 a memcpy to move the list down (instead of a for loop).
2984 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
2985 ext2fs_icount_increment, ext2fs_icount_decrement): Check
2986 to see if the inode is within bounds; if it isn't, return
2989 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
2990 when a bad inode number is passed to test_generic_bitmap
2991 to be EXT2FS_TEST_ERROR instead of the wrong
2992 EXT2FS_UNMARK_ERROR.
2994 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
2996 * Release of E2fsprogs version 1.07
2998 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3000 * Makefile.in (ELF_VERSION): Change version to be 2.2
3002 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3004 * alloc.c (ext2fs_get_free_blocks): Change routine to use
3005 ext2fs_fast_test_block_bitmap_range().
3007 * bitops.h (ext2fs_fast_test_block_bitmap_range,
3008 ext2fs_test_block_bitmap_range: New inline functions which
3009 test to see whether a contiguous range of blocks is
3012 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3014 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
3015 use ext2fs_badblocks_* instead of badblocks_*
3017 * bb_compat.c: New file which translates between old badblocks_*()
3018 names to ext2fs_badblocks_*()
3020 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
3021 link.c (since e2fsck doesn't use ext2fs_unlink()).
3023 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
3024 bitmap resizing routine moved from bitmaps.c, since e2fsck
3025 doesn't need to use this function.
3027 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
3028 since e2fsck only needs ext2fs_lookup.
3030 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3032 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
3033 already set; this is needed so that programs like dump
3034 which use the inode scan functions will deal with
3035 filesystems that have bad blocks in the inode table.
3037 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3039 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
3040 Moved to ext2fsP.h, since it doesn't need to be part of
3041 the public interface.
3043 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
3045 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3047 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
3048 directory block list abstraction. (Code moved from
3051 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
3052 to inode.c (since no one else should be peeking inside it!)
3054 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
3056 * openfs.c (ext2fs_open): Check the feature set in the ext2
3057 superblock, and refuse to open filesystems if they contain
3058 incompatible features. (Can be overriden with the
3061 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3063 * block.c (ext2fs_block_iterate2): Added new function
3064 ext2fs_block_iterate2 which changes the function
3065 signature of the callback function to include the
3066 referencing block and offset.
3068 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
3069 ext2fs_inode_scan_goto_blockgroup which allows an
3070 application to jump to a particular block group while
3071 doing an inode scan.
3073 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3075 * dirblock.c: Include string.h, since we use memcpy().
3077 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3079 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
3080 a long not an int; this doesn't matter on i386 machines,
3081 but it does on Alpha's.
3083 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3085 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
3086 table pointer is NULL, then return an error indicating
3087 that the inode table is missing.
3088 (get_next_blockgroup, get_next_blocks,
3089 ext2fs_get_next_inode): Don't treat a missing inode table
3090 as permanent error. Return MISSING_INODE_TABLE, but as an
3091 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
3093 * rw_bitmaps.c (ext2fs_write_block_bitmap,
3094 ext2fs_write_inode_bitmap): If the inode or block bitmap
3095 block is zero, then don't write out the inode or block
3096 bitmap. The idea here is to avoid stomping on the
3098 (read_bitmaps): If the inode or block bitmap block is
3099 zero, then fill in that portion of the inode or block
3100 bitmap with all zeros.
3102 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
3103 blocks in inode table when the inode table size is
3104 non-standard (and can therefore span blocks).
3106 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3108 * alloc.c (ext2fs_new_block): Fix fencepost error in
3109 ext2fs_new_block; make sure we don't try to allocate the
3110 first block beyond the end of the filesystem.
3112 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3114 * inode.c (check_for_inode_bad_blocks): New function called by
3115 get_next_blocks() to avoid reading in bad blocks marked in
3116 fs->badblocks. Inodes located in bad blocks are returned
3117 by ext2fs_get_next_inode() returns the error code
3118 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
3120 * alloc_tables.c (ext2fs_allocate_tables): New function which
3121 performs the part of mke2fs's job of allocating the
3124 * test_io.c (test_close): IO manager which is used for testing
3127 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3129 * inode.c (ext2fs_get_next_inode): Separate out the function of
3130 setting up for a new block group to get_next_blockgroup().
3131 Separate out the function of reading in blocks of the
3132 inode table to get_next_blocks().
3134 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
3136 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
3137 blocks to the badblock list in sorted order. This allows
3138 badblocks_list_test to be coded using a binary search for
3141 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3143 * Release of E2fsprogs version 1.06
3145 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3147 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
3148 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
3151 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
3152 set, then only write out the master superblock.
3154 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3156 * block.c (ext2fs_block_iterate): Fixed bug which caused
3157 block_iterate to fail to handle HURD created filesystems;
3158 it tested the inode translator field before the inode was
3161 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3163 * initialize.c (ext2fs_initialize): Make sure the description for
3164 the inode bitmap is set correctly.
3166 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

3172 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3174 * initialize.c: Override the kernel's idea of default
3175 checkinterval from 0 (never) to 180 days.
3177 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3179 * namei.c (ext2fs_namei_follow): New function which follows
3180 symbolic link (if any) at the target.
3182 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3184 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
3185 for shortcut function fs->read_inode() and fs->write_inode().

3189 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
3192 * namei.c (ext2fs_follow_link): New function.
3193 (ext2fs_namei): Extended to have support for chasing
3194 symbolic links. ext2fs_namei() still returns an inode
3195 which is a symbolic link. Symbolic links are only chased
3196 while resolving the containing directory. To chase
3197 symbolic links of the final result, use
3198 ext2fs_follow_link().
3200 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3202 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.

3209 * initialize.c (ext2fs_initialize): On systems where the byte
3210 order is not i386 compatible, set the swap_byte flag.
3212 * inode.c (inocpy_with_swap): Check to see if inode contains a
3213 fast symlink before swapping the inode block fields. This
3214 required adding a new argument to inocpy_with_swap to
3215 determine whether the mode field is in host order or not.
3217 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3219 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
3220 the sparc, if EXT2_STD_BITOPS set, use the standard
3221 i386-compatible bitmask operations, instead on the
3222 non-standard native bitmask operators.

3226 * block.c (ext2fs_block_iterate): Cause block iterator to return
3227 the HURD translator block (along with everything else).
3228 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
3229 iterator, then don't return any meta data blocks
3230 (including the HURD translator).
3232 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3234 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
3236 * uuid.c: New file, containing UUID utility functions.
3238 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

3242 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3244 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
3246 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3248 * openfs.c (ext2fs_open): If the blocksize in the superblock is
3249 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
3250 that's a basic value that must be correct for the rest of
3251 the library to work.
3253 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
3256 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

3267 Change the m68k bit numbering for bitmasks to match with
3268 the bit numbering used by all other ext2 implementations.
3270 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
3272 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

3305 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3306 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
3307 to avoid conflicts with with kernel include files. Also
3308 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
3311 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
3313 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c

3333 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
3336 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
3338 * unix_io.c (unix_open): Add a double check; if the passed in name
3339 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
3341 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
3343 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

3365 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
3366 Move these functions to freefs.c.
3368 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
3369 descriptors shadow memory to keep purify quiet. (This
3370 also has the nice benefit that the unused portion of the
3371 shadow descriptors are zeroed out.)
3373 * dirblock.c (ext2fs_write_dir_block): We need to use
3374 dirent->rec_len *before* it's byteswapped to find the
3375 location of the next directory structure!
3377 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
3378 cause ext2fs_new_inode to loop infinitely if we're trying
3379 to allocate an inode in group #0 and there are no free
3380 inodes at all in the system.
3382 * closefs.c: #include <errno.h> if it exists.
3384 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

3392 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
3393 installation directories correctly.

3403 file containing functions for reading and writing
3404 directory blocks (byte swapping if necesssary)
3406 * block.c (block_iterate_ind, block_iterate_dind,
3407 block_iterate_tind): Byte swap the block addresses if
3408 EXT2_SWAP_BYTES is set (and swap them back before writing
3411 * inode.c (inocpy_with_swap): New function.

3413 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
3415 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
3416 the superblock and group descriptors before writing it out.
3418 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
3419 then set the EXT2_SWAP_BYTES and byte-swap the superblock
3420 and group descriptors.
3422 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
3423 to desp ext2 filesystem structures.
3425 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
3426 supplied by Pete A. Zaitcev so that the C language
3427 versions of these functions are more portable. They will
3428 now work on both little and big endian systems, and the
3429 assumption that 32-bit integers are used is gone.
3431 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
3432 doing byte swapping.
3434 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

3448 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
3449 if the magic number is correct, it will be allocated.
3451 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
3453 * block.c (block_iterate_ind, block_iterate_dind,
3454 block_iterate_tind): Don't recompute block_nr each loop;
3455 just increment it! Factor check of BLOCK_FLAG_APPEND out
3456 of the loop. Factor mask of BLOCK_CHANGED into changed
3457 variable out of the loop. (block_iterate_ind, in
3458 particular, gets called a lot, so every little
3459 optimization helps.)
3461 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
3463 * block.c (block_iterate_ind, block_iterate_dind,

3468 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
3469 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
3470 ext2fs_fast_test_inode_bitmap): Add fast version of these
3471 functions, which don't do range checking.

3474 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
3475 ext2fs_get_inode_bitmap_end): Add new accessor functions
3476 which return the start and end points of the bitmaps.
3478 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
3480 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
3481 instead of llseek. The errno if the offset is too large
3482 and lseek is not supported should be EINVAL, not -EINVAL.
3484 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
3486 * Makefile.in: Added support for ELF shared libraries.
3487 Fixed typos in the compilation rules.
3488 (distclean): Added Makefile.
3490 * llseek.c (llseek): New function, if llseek() does not exist in the

3494 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3496 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
3498 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

3502 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
3503 the S_*, which are normally defined in <sys/stat.h>. This
3504 allows us to compile e2fsprogs on a non-Linux system,
3505 which may have a different value for S_IFDIR.
3507 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3509 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
3510 this is a user-mode application!
3512 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
3514 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
3515 __linux__ so that non-linux systems won't see it.
3517 * alloc.c: Include <errno.h> if possible.
3518 * badblocks.c: Ditto.
3519 * bb_inode.c: Ditto.
3522 * expanddir.c: Ditto.
3523 * get_pathname.c: Ditto.
3524 * initialize.c: Ditto.
3531 * rw_bitmaps.c: Ditto.
3534 * Makefile.in: Rewritten to conform to GNU coding standards and
3535 support separate compilation directories.
3537 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
3539 * initialize.c (ext2fs_initialize): Don't allow more than one
3540 bitmaps's worth of inodes in a group.
3542 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
3544 * llseek.c (ext2_llseek): Added error checking to the llseek()
3545 compat code to protect against overflow. This only
3546 applies to 1.0 and early 1.1 kernels, which don't support
3547 the llseek() system call.
3549 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
3551 * unix_io.c (unix_open): Initialize the read_error and write_error
3552 io_channel pointers to be null.
3554 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
3555 found, clear it but don't try to update the filesystem
3556 accounting information, since that's hopeless anyway.
3558 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
3559 bloblock_iterate_tind): Check to see if the indirect blocks are
3560 valid before trying to read them.

3566 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
3567 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
3568 illegal block or inode number is passed in, return instead
3569 of trying to test, set, or clear the bit.
3571 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
3573 * Makefile: Added a dummy install target in case shared libraries

3584 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
3585 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
3586 ext2fs_free_block_bitmap): Add magic number checking for
3587 the inode and block bitmaps.
3589 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
3590 magic number for a block bitmap instead of an inode bitmap.

3612 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
3613 * read_bb.c (ext2fs_read_bb_inode):
3614 * read_bb_file.c (ext2fs_read_bb_FILE):

3639 structure magic numbers.
3641 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
3642 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
3643 someone uses the -b option to specify the use of the backup
3644 superblock --- this usually means that the main superblock is

3659 * initialize.c: Completely revamped the inode and block bitmap
3660 structures, so that they can be better chance of being extensible
3661 in a shared library. They are now their own type, instead of
3662 being a char *. Also, the function signatures of
3663 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
3664 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
3665 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
3666 changed to eliminate the ext2_filsys argument, since it is no

3671 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
3672 system call if available.
3674 * llseek.c: new file. This is the stub calling the llseek system
3675 call which allows supports for 2GB+ file systems.
3677 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
3678 the creator operating system.

3682 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
3683 the group descriptor statistics in addition to everything else.
3684 This relieves mke2fs of the responsibility of doing it.
3686 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
3687 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
3688 not the generic C function equivalents should be included or not.
3690 * openfs.c (ext2fs_open): If a superblock is specified, then use
3691 the backup group descriptors that go along with this superblock,
3692 instead of using the primary group descriptors. This allows
3693 e2fsck to recover filesystems where the primary group descriptors
