1 2006-11-11 Theodore Tso <tytso@mit.edu>
3 * swapfs.c (ext2fs_swap_super):
4 ext2_fs.h: Add definition of EXT4_FEATURE_INCOMPAT_64BIT,
5 which adds supports for 64-bit block count fields in the
6 superblock (s_blocks_count_hi, s_free_blocks_count_hi),
7 large group descriptors (s_desc_size), extents with high
8 16 bits (ee_start_hi, ei_leaf_hi), inode ACL (i_file_acl_hi)
10 * ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_DIR_NLINK,
11 which allow directories to have > 65000 subdirectories
12 (i_nlinks) by setting i_nlinks = 1 for such directories.
13 RO_COMPAT protects old filesystems from unlinking such
14 directories incorrectly and losing all files therein.
16 * swapfs.c (ext2fs_swap_group_desc):
17 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
18 which adds a crc16 checksum in the group descriptor,
19 (s_uuid[16] | __u32 group | ext3_group_desc
20 (excluding gd_checksum itself)). This allows the kernel
21 to more safely manage UNINIT groups. Also adds an
22 bg_itable_unsued which indicates how many inodes are
23 uninitialized in the block group.
25 * swapfs.c (ext2fs_swap_inode_full):
26 ext2_fs.h: Add definition of EXT4_FEATURE_RO_COMPAT_HUGE_FILE,
27 which changes i_blocks to be in units of s_blocksize units
28 instead of 512-byte sectors, use l_i_frag and l_i_fsize as
31 2006-10-02 Eric Sandeen <esandeen@sandeen.net>
33 * getsize.c (ext2fs_get_device_size): Check to make sure that the
34 number of blocks doesn't overflow the retblocks return
35 parameter for regular files using stat64().
37 2006-10-01 Theodore Tso <tytso@mit.edu>
39 * bitops.h (ext2fs_swab32): Only include ext2fs_swab32() if
40 EXT2FS_ENABLE_SWAPFS is defined.
42 2006-08-30 Eric Sandeen <esandeen@redhat.com>
44 * initialize.c (ext2fs_initialize): Make sure inode count does
47 2006-08-30 Eric Sandeen <esandeen@redhat.com>
49 * alloc_tables.c (ext2fs_allocate_group_table):
50 * check_desc.c (ext2fs_check_desc):
51 Use new inlines to calculate group first & last blocks.
53 Create new inlines to calculate first/last group blocks.
55 2006-08-30 Eric Sandeen <esandeen@redhat.com>
57 * bmove.c (process_block):
59 * icount.c (ext2fs_create_icount2, insert_icount_el):
60 * tst_badblocks.c (print_list, validate_test_seq, do_test_seq):
61 * tst_badblocks.c (invalid_proc):
62 * tst_getsize.c (main):
63 * tst_iscan.c (check_map):
64 * unix_io.c (raw_read_blk, unix_read_blk):
65 * write_bb_file.c (ext2fs_write_bb_FILE): Fix printf formats.
67 2006-08-30 Eric Sandeen <esandeen@redhat.com>
69 * closefs.c (write_backup_super):
70 * initialize.c (ext2fs_initialize): Remove unused variables.
72 2006-08-30 Eric Sandeen <esandeen@redhat.com>
74 * check_desc.c (ext2fs_check_desc): avoid overflows when iterating
75 over group descriptors on very large filesystems.
77 2006-08-30 Theodore Tso <tytso@mit.edu>
79 * bitmaps.c (ext2fs_set_bitmap_padding): Fix potential overflow
80 problems when the number of blocks is close to 2**31.
82 * ext2fs.h (ext2fs_div_ceil): Add new function which safely
83 calculates an integer division where the result is always
84 rounded up while avoiding overflow errors.
86 * initialize.c (calc_reserved_gdt_blocks, ext2fs_initialize):
87 * openfs.c (ext2fs_open2): Use ext2fs_div_ceil() instead of a
88 using an open-coded expression which was subject to
91 2006-08-06 Andreas Dilger <adilger@clusterfs.com>
93 * bitops.h (ext2fs_cpu_to_le32, ext2fs_le64_to_cpu,
94 ext2fs_swab64): Add 64-bit byte swapping functions
96 2006-08-05 Theodore Tso <tytso@mit.edu>
98 * ext2_fs.h (EXT4_EXTENTS_FL): Rename EXT3_EXTENTS_FL to
99 EXT4_EXTENTS_FL, and add EXT4_EXTENTS_FL to user visible
102 2006-07-15 Theodore Tso <tytso@mit.edu>
104 * ext2fs.h: Remove unneeded #ifdef since EXT2_DYNAMIC_REV is
105 always defined in the e2fsprogs-provided ext2_fs.h
107 2006-05-21 Theodore Tso <tytso@mit.edu>
109 * openfs.c (ext2fs_open2): Fix type warning problem with sizeof()
111 2006-05-12 Theodore Tso <tytso@mit.edu>
113 * alloc_tables.c (ext2fs_allocate_group_table): When allocating
114 space for the RAID filesystems with the stride parameter,
115 place each portion of the group's inode table right up
116 after the superblock (if present) in order to minimize
117 fragmentation of the freespace.
119 2006-05-08 Theodore Tso <tytso@mit.edu>
121 * rw_bitmaps.c (write_bitmaps, read_bitmaps): Added support for
122 lazy blockgroups. If a block group has flags indicating
123 that its block or inode data structures have not been
124 initialized, skip reading or writing that portion of the
127 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode_full): When
128 scanning a filesystem with lazy blockgroups, skip
129 uninitialized portions of the inode table when iterating
130 over the block group.
132 * swapfs.c (ext2fs_swap_group_desc): Byte swap the bg_flags field.
134 * ext2fs.h: Define the a new internal flag, EXT2_SF_DO_LAZY, so
135 that the inode interator knows compat_lazy_bg feature is
136 enabled. Declare that this version of e2fsprogs supports
137 the EXT2_FEATURE_COMPAY_LAZY_BG feature.
139 * ext2_fs.h (struct ext2_group_desc): Use the bg_pad field for
140 bg_flags, and define the flags EXT2_BG_INODE_UNINIT and
141 EXT2_BG_BLOCK_UNINIT. These flags are only honored if
142 EXT2_FEATURE_COMPAT_LAZY_BG feature is enabled (also
145 2006-04-23 Theodore Ts'o <tytso@mit.edu>
147 * rw_bitmaps.c (write_bitmaps, ext2fs_write_inode_bitmap,
148 ext2fs_write_block_bitmap, ext2fs_write_bitmaps): Reduce
149 disk seeks by writing the inode and block bitmaps in an
152 2006-04-09 Theodore Ts'o <tytso@mit.edu>
154 * ext2_types.h.in, Makefile.in, tst_types.c: Use the asm_types.h
155 file to define the __[us]{8,16,32,64} types. Add a
156 tst_types program to make sure the types are correct.
158 2006-04-04 Theodore Ts'o <tytso@mit.edu>
160 * mkjournal.c (ext2fs_add_journal_inode): If the filesystem is
161 opened in exclusive mode, then device will be busy by
162 definition, so don't return -EBUSY. This caused mke2fs -j
163 to fail on the 1.39-WIP (29-Mar-2006) release. (Addresses
166 2006-03-29 Theodore Ts'o <tytso@mit.edu>
168 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit): Fix the constraints
169 so that GCC knows that the ext2fs_set/clear_bit reads and
172 2006-03-25 Theodore Ts'o <tytso@mit.edu>
174 * Makefile.in: Check the bitfield operations much more carefully,
175 and arrange to have tst_bitops run from "make check"
177 * tst_bitops.c: Enahce tst_bitops program so that it is much more
178 thorough in testing bit optations.
180 * bitops.h: Add new functions ext2fs_fast_set_bit() and
181 ext2fs_fast_clear_bit() and make the x86 functions 32-bit
182 clear. Change the fast inode and block mark/unmark
183 functions to use ext2fs_fast_set/get_bit()
185 2006-03-18 Theodore Ts'o <tytso@mit.edu>
187 * ext2fs.h (EXT2_FLAG_EXCLUSIVE): Define new flag which requests
188 that the io_channel be opened in exclusive mode.
190 * openfs.c (ext2fs_open2), initialize.c (ext2fs_initialize): If
191 EXT2_FLAG_EXCLUSIVE is passed to ext2fs_open or
192 ext2fs_initialize, then pass IO_FLAG_EXCLUSIVE to the
193 io_channel open routine.
195 * ext2_io.h (IO_FLAG_EXCLUSIVE), unix_io.c (unix_open): Add new
196 io_channel open flag, IO_FLAG_EXCLUSIVE, which requests
197 that the device be opened in exclusive (O_EXCL) mode.
199 * ext2fs.h: Fix documentation so that BLOCK_FLAG_TRAVERSE is
200 BLOCK_FLAG_DEPTH_TRAVERSE. (Addresses Debian Bug #351268)
202 2006-03-17 Theodore Ts'o <tytso@mit.edu>
204 * initialize.c (calc_reserved_gdt_blocks): Fix a signed vs
205 unsigned problem which caused mke2fs -O resize_inode to
206 bomb out on large filesystems. (Addresses Debian Bug
209 * ext2_fs.h (EXT2_IOC_GETVERSION_NEW, EXT2_IOC_SETVERSION_NEW,
210 EXT2_IOC_GROUP_EXTEND, EXT2_IOC_GROUP_ADD): Add ioctl
213 2005-12-10 Theodore Ts'o <tytso@mit.edu>
215 * Makefile.in: Add a dependency to make sure that the
216 subdirectories are created before creating all of the
219 2005-12-10 Theodore Ts'o <tytso@mit.edu>
221 * res_gdt.c (ext2fs_create_resize_inode): Fix type-punning warning.
223 * read_bb_file.c (ext2fs_read_bb_FILE): Use a data structure
224 instead of stuffing a function pointer dirctly into a void
225 pointer, since that isn't portable.
227 * mkjournal.c (ext2fs_add_journal_inode): Fix possiblely
228 uninitialized use of variable warning.
230 * initialize.c (calc_reserved_gdt_blocks): Fix signed vs. unsigned
233 * ext2fs.h: Make the type of the 'now' field to be time_t to avoid
234 gcc -Wall complaints.
236 * bitops.h (ext2fs_find_first_bit_set): Fix signed vs unsigned
239 * tst_badblocks.c (file_test_invalid): Add test which confirms
240 proper detection of invalid block numbers in
241 ext2fs_read_bb_FILE().
243 2005-11-20 Theodore Ts'o <tytso@mit.edu>
245 * bitops.h: We no longer have the sparc assembly code in the
246 header file any more, so we shouldn't set
247 _EXT2_HAVE_AS_BITOPS_. This would break compiles on the
248 sparc architectures when using gcc.
250 2005-11-13 Theodore Ts'o <tytso@mit.edu>
252 * ext2fs.h: Add #include <string.h> since the inline functions use
253 memcpy(). (Addresses Sourceforge Bug #1251062)
255 2005-11-09 Theodore Ts'o <tytso@mit.edu>
257 * Fix a bug when writing an external journal device on an big
258 endian machine (such as a S/390), where when the number of
259 block groups is zero, we never end up writing out the
260 primary superblock at all.
262 2005-09-24 Theodore Ts'o <tytso@mit.edu>
264 * ext2fs.h, bb_inode.c, closefs.c, initialize.c, mkdir.c,
265 mkjournal.c, res_gdt.c: If fs->now is non-zero, use that
266 as the time instead of the system time when setting
267 various filesystem fields (last modified time, last write
270 2005-08-28 Matthias Andree <matthias.andree@gmx.de>
272 * Fix compiler warnings about missing memcpy prototypes.
274 2005-07-25 Theodore Ts'o <tytso@mit.edu>
276 * test_io.c (safe_getenv): Pass in zero to the unusued arguments
277 of prctl(PR_GET_DUMPABLE) to avoid false positives from
280 2005-07-19 Theodore Ts'o <tytso@mit.edu>
282 * mkjournal.c (ext2fs_add_journal_inode): Check for the case where
283 the filesystem is apparently not mounted, but the device
284 is still busy. This can happen when the luser doesn't
285 bother to mount /proc and has a bogus /etc/mtab, but still
286 wants to mount the filesystem before using tune2fs(?!?).
287 Add a safety check to save him from his own stupidity, at
288 least on 2.6 kernels. (Addresses Debian Bug #319002)
290 2005-07-09 Andreas Dilger <adilger@clusterfs.com>
292 * getsize.c (ext2fs_get_device_size): Use fstat/fstat64 to get
293 size of regular files. Fix file descriptor leaks in error
296 2006-06-30 Theodore Ts'o <tytso@mit.edu>
298 * Release of E2fsprogs 1.38
300 2005-06-30 Theodore Ts'o <tytso@mit.edu>
302 * bitops.h, bitops.c (ext2fs_set_bit, ext2fs_clear_bit,
303 ext2fs_test_bit): Change these function prototypes to be
304 unsigned int's. Negative bit numbers were never allowed
305 (and never made any sense), so this should be a safe
306 change. This is needed to allow safe use of block numbers
307 greater than or equal to 2**31.
309 2005-06-27 Stephen Tweedie <sct@redhat.com>
311 * ext2fs.h (ext2fs_resize_mem): Fix C99 strict type aliasing
312 problems. Addresses Red Hat Bugzilla #161183.
314 2005-06-19 Theodore Ts'o <tytso@mit.edu>
316 * getsectsize.c (BLKSSZGET): Clean up test for when to manually
317 define the BLKSSZGET ioctl.
319 2005-05-29 Theodore Ts'o <tytso@mit.edu>
321 * ismounted.c (ext2fs_check_mount_point): Add test to see if the
322 device appears to be busy; this only works on Linux 2.6+
323 systems, but provides some additional bullet-proofing in
326 2005-05-08 Theodore Ts'o <tytso@mit.edu>
328 * test_io.c (safe_getenv): Fix bug so it would fetch the right
329 environment variable.
331 2005-04-09 Theodore Ts'o <tytso@mit.edu>
333 * inode.c (ext2fs_write_new_inode),
334 ind_block.c (ext2fs_read_ind_block): Add missing return
335 value in error return case. (Otherwise we return garbage
336 instead of the error code.)
338 2005-03-31 Theodore Ts'o <tytso@mit.edu>
340 * test_io.c (test_open): If called by a setuid/setgid or an
341 otherwise privileged program, be paranoid and ignore the
342 TEST_IO_* environment variables.
344 2005-03-21 Theodore Ts'o <tytso@mit.edu>
346 * Release of E2fsprogs 1.37
348 2005-03-21 Theodore Ts'o <tytso@mit.edu>
350 * ext2_ext_attr.h (EXT2_XATTR_LEN, EXT2_XATTR_SIZE): Add new
351 convenience cpp macros.
353 2005-03-20 Theodore Ts'o <tytso@mit.edu>
355 * mkdir.c (ext2fs_mkdir): Call ext2fs_write_new_inode() instead of
356 ext2fs_write_inode().
358 * inode.c (ext2fs_write_new_inode): New function which should be
359 used when the caller is writing an inode for the first
360 time. It makes sure that the extra portion of the large
361 inode is initialized properly.
363 2005-03-18 Theodore Ts'o <tytso@mit.edu>
365 * Makefile.in: Fix clean target to remove tst_getsectsize.
367 * getsize.c (ext2fs_get_device_size): Check to see if the number
368 of blocks is greater than 2**32 when we are doing a binary
369 search to determine the device size. Thanks to Stephen
370 Tweedie for the patch.
372 2006-02-05 Theodore Ts'o <tytso@mit.edu>
374 * Release of E2fsprogs 1.36
376 2005-02-05 Theodore Ts'o <tytso@mit.edu>
378 * Makefile.in: Remove ext2fs.pc on a "make distclean"
380 2005-02-04 Theodore Ts'o <tytso@mit.edu>
382 * Makefile.in (clean): Remove tst_getsize when doing a make clean
384 2005-02-03 Theodore Ts'o <tytso@mit.edu>
386 * bitops.c: Make the generic functions more efficient.
388 * bitops.h: Drop SPARC assembly code. It's less efficient than GCC
389 3.4 compiled code and also triggers nasty compiler
390 warnings on sparc64. Thanks to Matthias Andree for his
391 analysis and suggestion.
393 2005-01-27 Theodore Ts'o <tytso@mit.edu>
395 * res_gdt.c (ext2fs_create_resize_inode): Create the resize inode
396 even if s_reserved_gdt_blocks is zero.
398 2005-01-26 Theodore Ts'o <tytso@mit.edu>
400 * ext2fs.pc.in: Add pkg-config files.
402 2005-01-25 Theodore Ts'o <tytso@mit.edu>
404 * ext2fs.h: Add definition of struct ext2_inode_large
406 * ext2_fs.h: Add new function prototypes
408 * ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr): The
409 ext2fs_swap_ext_attr() has been moved to swapfs.c, and
410 given a new argument, has_header.
412 * swapfs.c (ext2fs_swap_ext_attr): Moved from ext_attr.c, and
413 takes an argument which controls whether or not there is
414 an EA header which needs to be byteswaped.
415 (ext2fs_swap_inode_full): New function which byte-swaps
418 * inode.c (ext2fs_get_next_inode_full, ext2fs_read_inode_full,
419 ext2fs_write_inode_full): New functions, originally from
420 Alex Tomas, but which needed to be substantially fixed so
421 that the tests wouldn't cause major stack overwrite bugs
422 in byte-swapping is enabled.
424 2005-01-18 Theodore Ts'o <tytso@mit.edu>
426 * Makefile.in: Fix the kernel compile-time echo commands to be
427 consistent and portable
429 2005-01-07 Theodore Ts'o <tytso@mit.edu>
431 * unlink.c (ext2fs_unlink): If both the name and the inode number
432 are unspecified, then return an error, so that we don't do
433 something surprising such as unconditionally deleting the
434 first directory entry.
435 (unlink_proc): Delete directory entries by coalescing it
436 with the previous entry, to avoid directory fragmentation.
438 2005-01-06 Theodore Ts'o <tytso@mit.edu>
440 * version.c (ext2fs_parse_version_string): Change parsing
441 algorithm so that version strings such as 1.36-rc1 returns
442 a non-surprising result (i.e., 136, and not 1361).
444 2005-01-05 Theodore Ts'o <tytso@mit.edu>
446 * block.c (block_iterate_ind, block_iterate_dind,
447 block_iterate_tind): Move the code which byte swaps and
448 read/writes indirect blocks to ext2fs_{read,write}_ind_block.
449 This saves 400 bytes, and we need them for the
450 resize_inode handling.
452 * ind_block.c (ext2fs_read_ind_block, ext2fs_write_ind_block): New
455 * res_gdt.c (ext2fs_create_resize_inode): Use
456 ext2fs_{read,write}_ind_block so that byte swapping is
457 handled on big-endian systems.
459 * dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handle
460 has its own copy of the orig_super data structure. (This
461 is a better way of fixing a double-free problem in
462 resize2fs which Fedora attempted to fix in
463 e2fsprogs-1.35-double_free.patch. Addresses Red Hat
466 2004-12-23 Theodore Ts'o <tytso@mit.edu>
468 * inode.c (ext2fs_flush_icache): When flushing the icache, clear
469 the last-read block information as well.
471 * ext2fs.h (BMAP_SET), bmap.c (ext2fs_bmap): Add support for new
472 flag, BMAP_SET, which allows the caller to set a
473 particular logical->physical block mapping.
475 * ext2_err.et.in (EXT2_ET_SET_BMAP_NO_IND): New error code
477 * initialize.c (calc_reserved_gdt_blocks): #ifdef out all
478 debugging printf statements.
480 * res_gdt.c (ext2fs_create_resize_inode): Return
481 EXT2_ET_RESIZE_INODE_CORRUPT if the resize inode is not
482 what we expect. #ifdef out all debugging printf
485 * ext2_err.et.in (EXT2_ET_RESIZE_INODE_CORRUPT): Add new error code.
487 2004-12-22 Theodore Ts'o <tytso@mit.edu>
489 * swapfs.c (ext2fs_swap_super): Byteswap the reserved_gdt_blocks
492 2004-12-15 Theodore Ts'o <tytso@mit.edu>
494 * sparse.c (ext2fs_list_backups, ext2fs_bg_has_super),
495 res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
496 ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
497 ext2fs_bg_has_super() back to closefs.c. There's no
498 reason for the new file, since list_backups() isn't being
499 used by any other functions, and can be made static, and
500 all users of the ext2fs filesystem will have to call
501 ext2fs_close() anyway.
503 2004-12-15 Theodore Ts'o <tytso@mit.edu>
505 * Applied resize inode patch from Andreas Dilger
507 * res_gdt.c (ext2fs_create_resize_inode): New function that
508 creates the resize inode.
510 * initialize.c (ext2fs_initialize): Reserve space for the resize
513 * ext2fs.h (EXT2_LIB_FEATURE_COMPAT_SUPP): Add
514 EXT2_FEATURE_COMPAT_RESIZE_INODE to the list of supported
516 Add function prototypes for res_gdt.c and sparse.c.
518 * closefs.c (ext2fs_super_and_bgd_loc): Take the reserved blocks
519 into account when calculating the number of overhead
522 * closefs.c (ext2fs_bg_has_super, test_root), sparse.c: Move these
523 functions to the new file sparse.c
525 * alloc_sb.c (ext2fs_reserve_super_and_bgd): Reserve the blocks
526 saved in the resize inode as being in use.
528 * ext2_err.et.in (EXT2_ET_RES_GDT_BLOCKS): Add new error code.
530 * Makefile.in (srcdir): Add res_gdt.c and sparse.c to the ext2fs
533 2004-12-14 Theodore Ts'o <tytso@mit.edu>
535 * Makefile.in: Use Linux-kernel-style makefile output for "make
538 * Makefile.in (installdirs): Use $(MKINSTALLDIRS) macro
541 2004-11-30 Theodore Ts'o <tytso@mit.edu>
543 * unix_io.c (unix_set_option): Add support for the offset option.
545 * test_io.c (test_set_option): Add support for the set_option method.
547 * ext2_io.h: Add new io_channel method, set_option(), and change
548 io_channel_write_byte() from a macro to a library function.
550 * ext2fs.h, openfs.c(ext2fs_open2): New version of ext2fs_open
551 which adds a new parameter, io_options.
552 (ext2fs_open): If there is a question mark in the
553 filename, and no io_options are specified, assumed that
554 the text following the question mark are io_options.
556 * io_manager.c, Makefile.in: New source file which contains
557 high-level functions for the io_channel layer.
559 * freefs.c (ext2fs_free): Make sure we don't free the io_channel

569 feature and inode flag. Change maximum allowable block
572 2004-10-08 Theodore Ts'o <tytso@mit.edu>
574 * getsize.c (ext2fs_get_device_size): Add support for Windows
575 9x/NT under Cygwin. Thanks to Sam Robb

591 read the metadata from fs->image_io instead of fs->io.
593 * initialize.c (ext2fs_initialize), openfs.c (ext2fs_open):
594 Initialize fs->image_io to be the same as fs->io.
596 * ext2_err.et.in (EXT2_ET_NOT_IMAGE_FILE): Add new error code.
598 * openfs.c (ext2fs_get_data_io, ext2fs_set_data_io,

614 Metacompilation group for pointing a potential ordering
615 constraint problem if we don't write things out in the
618 * test_io.c: Implement the ability to abort after n reads or
619 writes to a particular block. The block is specified by
620 TEST_IO_BLOCK environment variable, and the read/write
621 count by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT
622 environment variables. The block data is now only dumped
623 if the 0x10 bit is set in TEST_IO_FLAGS.
625 2004-04-03 Theodore Ts'o <tytso@mit.edu>
627 * ext2_types.h.in: Remove check for _UUID_TYPES since uuid_types.h

632 * getsize.c (ext2fs_get_device_size): Only use the BLKGETSIZE64
633 ioctl on Linux 2.6 since it is unreliable in Linux 2.4.
634 (Addresses Debian Bug #236528). Fix typo in the ioctl
637 2004-03-02 Theodore Ts'o <tytso@mit.edu>
639 * getsize.c (ext2fs_get_device_size): Update getsize functions to
640 use Apple Darwin and Linux 64-bit ioctl's
642 2004-02-29 Brian Bergstrand <brian@bergstrand.org>
644 * Makefile.in: Use $(BSDLIB_PIC_FLAG) to determine whether to use

665 which we're using due to a typo in the e2fsck code. (Oops)
667 * swapfs.c (ext2fs_swap_inode): Fix byte swap bug which causes SE
668 Linux created symlinks with mandatory attributes to fail
669 to be properly handled on big endian systems. (Addresses
671 (ext2fs_swap_super): Byte swap some new fields in the
672 superblock, including the journal backup fields.
674 2003-12-02 Theodore Ts'o <tytso@mit.edu>
676 * alloc.c, bb_inode.c, bitops.c, block.c, check_desc.c, closefs.c,

680 rw_bitmaps.c, unix_io.c, unlink.c, write_bb_file.c: Fix
681 gcc -Wall complaints. Mainly marking variables as being
682 unsued, and catching signed vs. unsigned comparisons.
684 2003-09-03 Theodore Ts'o <tytso@mit.edu>
686 * closefs.c (ext2fs_super_and_bgd_loc): New function which
687 centralizes the calculation of the superblock and block
689 (ext2fs_flush): Use ext2fs_super_and_bgd_lock to figure
690 out where to write the superblock and block group
693 * alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which

695 ext2fs_super_and_bgd_loc.
697 * initialize.c (ext2fs_initialize): Use
698 ext2fs_reserve_super_and_bgd to initialize the block bitmap.
700 2003-08-20 Theodore Ts'o <tytso@mit.edu>
702 * inode_io.c (ext2fs_inode_io_intern2), ext2fs.h: Add new function
703 allows the caller to pass in the inode data structure.
705 * fileio.c (ext2fs_file_open2), ext2fs.h: Add new function which
706 allows the caller to pass in the inode to be used in the
709 * ext2_fs.h: Add a backup of the location of the journal inode
710 blocks to the superblock.
712 * mkjournal.c (write_journal_inode): Save the location of the
713 journal inode to the backup location in the superblock.
715 2003-08-01 Philipp Thomas <pthomas@suse.de>

722 mkjournal.c, namei.c, newdir.c, openfs.c, rs_bitmap.c,
723 rw_bitmaps.c, test_io.c, unix_io.c: ext2fs_getmem(),
724 ext2fs_free_mem(), and ext2fs_resize_mem() all now take a
725 'void *' instead of a 'void **' in order to avoid pointer
726 aliasing problems with GCC 3.x.
728 2003-07-25 Theodore Ts'o <tytso@mit.edu>
730 * Release of E2fsprogs 1.34
732 2003-07-06 Theodore Ts'o <tytso@mit.edu>
734 * kernel-jbd.h, flushb.c: Fix gcc -Wall nitpicks (indented cpp
737 * ext2_types.h.in, initialize.c: Fix gcc -Wall nitpicks
740 * ismounted.c: Fix gcc -Wall nitpicks (Don't use exit as a goto label)
742 * llseek.c: Fix gcc -Wall nitpicks (don't use #elsif)
744 * lookup.c, read_bb.c: Fix gcc -Wall nitpicks (indent
745 non-traditional #pragma)
747 * test_io.c: Fix gcc -Wall nitpicks (const/unsigned type issues)
749 2003-06-24 <tytso@snap.thunk.org>

760 returns the hardware sector size (if it is available).
762 2003-05-13 Theodore Ts'o <tytso@mit.edu>
764 * unix_io.c: Add #ifdef NO_IO_CACHE which disables all userspace
765 caching by the unix_io layer. Not enabled, only for
768 2003-05-05 Theodore Ts'o <tytso@mit.edu>
770 * test_io.c: Pay attention to the environment variables
771 TEST_IO_LOGFILE, TEST_IO_FLAGS, and TEST_IO_BLOCK to
772 determine whether or not we should log io activity, and to
775 2003-05-03 Theodore Ts'o <tytso@mit.edu>
777 * tst_badblocks.c (file_test): Use tmpfile() instead of mktemp().
779 2003-04-29 Theodore Ts'o <tytso@mit.edu>
781 * getsize.c (ext2fs_get_device_size): Allow windows code to get
782 the resize for filesystems that are in regular files.
784 2003-04-21 Theodore Ts'o <tytso@mit.edu>
786 * Release of E2fsprogs 1.33
788 2003-04-21 Theodore Ts'o <tytso@mit.edu>
790 * Makefile.in: Use DYLD_LIBRAY_PATH so that "make check" works on
791 Darwin systems when building with shared libraries.
793 2003-04-18 Theodore Ts'o <tytso@mit.edu>
795 * unix_io.c: Use __CYGWIN__ instead of CYGWIN.

799 * getsize.c: Add Cygwin/Windows version of ext2fs_get_device_size()
801 2003-04-12 Theodore Ts'o <tytso@mit.edu>

804 device only accepts sector aligned read requests.
806 * ismounted.c (check_mntent_file): Deal with OS's that don't
809 * imager.c: If the OS doesn't define ssize_t, typedef it to int.
811 2003-04-11 Theodore Ts'o <tytso@mit.edu>
813 * ext2_fs.h (EXT2_FEATURE_RO_COMPAT_BTREE_DIR): Comment out unused
816 2003-03-30 Theodore Ts'o <tytso@mit.edu>
818 * Makefile.in: Use the compile_et --build-tree option.
820 2003-03-14 Theodore Ts'o <tytso@mit.edu>
822 * getsize.c: Add support for Apple Darwin's ioctl to get the hard
825 * badblocks.c (ext2fs_u32_list_count), ext2fs.h: Add new function
826 which returns the number of entries in the list.
828 2003-03-10 Theodore Ts'o <tytso@mit.edu>
830 * fileio.c (ext2fs_file_lseek): Fix bug added when adding 64-bit
831 support; avoid null dereference when ret_pos is NULL.
833 2003-03-06 Theodore Tso <tytso@mit.edu>
835 * ext2_types.h.in: Don't redefine types if other e2fsprogs
836 *_types.h files have been included already.
838 * kernel-jbd.h: Use C99 variadic cpp macros if not using GCC.
839 (Older GCC's don't support the C99 variadic macros.)
841 * flushb.c (ext2fs_sync_device),
842 ismounted.c (ext2fs_check_mount_point): Avoid GCC extension:
843 #warning not supported by Solaris suncc
845 * ext2_ext_attr.h: Avoid GCC extension: 0 length arrays in
846 structure definition. Not needed for now in
849 2003-01-25 Theodore Ts'o <tytso@mit.edu>
851 * dirhash.c: Fix gcc -Wall nits.
853 2003-01-22 Theodore Ts'o <tytso@mit.edu>
855 * unix_io.c (unix_write_blk): Fix up GCC -Wall nits.
857 2003-01-21 Theodore Ts'o <tytso@mit.edu>
859 * fileio.c (ext2fs_file_read, ext2_file_lseek,
860 ext2_file_get_size): Add 64-bit support.
862 * ext2fs.h (EXT2_I_SIZE): Add macro which caluates a 64bit size
863 from i_size and i_size_high.
865 2003-01-19 Theodore Ts'o <tytso@mit.edu>
867 * initialize.c (ext2fs_initialize): If the user specifies a really
868 large number of inodes, then reduce the number of blocks
869 per group until we find a workable set of filesystem
872 * ext2_err.et.in (EXT2_ET_TOO_MANY_INODES): Add new error code.
874 2002-11-09 Theodore Ts'o <tytso@mit.edu>
876 * Release of E2fsprogs 1.32
878 2002-11-09 Theodore Ts'o <tytso@mit.edu>
880 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
881 unix_write_blk): Optimize routines so that we don't end up
882 searching the cache twice when a block isn't in the
883 cache. If reads are larger than READ_DIRECT_SIZE, don't
884 let them go through the cache.
886 * unix_io.c (find_cached_block): Fixed bug which caused some clean
887 blocks to be erroneously marked as dirty, so they would
888 get written back to the disk before they are evicted from
889 the cache. Harmless, but it slows down e2fsck
892 2002-11-08 Theodore Ts'o <tytso@mit.edu>
894 * Release of E2fsprogs 1.31
896 2002-11-08 <tytso@snap.thunk.org>
898 * Makefile.in (check): Skip trying to compile test_byteswap
899 if --disable-byteswaap had been given to configure.
901 2002-11-07 <tytso@snap.thunk.org>
903 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
904 support when the MASTER_SB_ONLY flag is set. Some of
905 the descriptor blocks that should have been written out
906 were getting skipped.
908 2002-10-31 Theodore Ts'o <tytso@mit.edu>
910 * Release of E2fsprogs 1.30
912 2002-10-31 Theodore Ts'o <tytso@mit.edu>
914 * ext2_fs.h: Add support for a new inode flag, which is to be used
915 for indicating the top of directory hierarchies for the
916 Orlov block allocator.
918 * ismounted.c (check_mntent, check_mntent_file): Add better
919 support for loopback-mounted filesystems. Check /etc/mtab
920 if /proc/mounts doesn't turn up any mount flags, since
921 /etc/mtab has the loopback image filename, instead of
922 /dev/loop0. Also, check based on st_dev and st_ino, so
923 that if a relative pathname or a pathnames using symbolic
924 links are used, we can detect the the filesystem correctly
925 in those cases. (Addresses Sourceforge bug #619119)
927 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
928 don't try the FDFLUSH ioctl that was required for floppies
929 with older kernels. This avoids needless whining from the
930 MD device driver. (Addresses Sourceforge bug #545832).
932 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
933 wrong group_block to ext2fs_descriptor_block_loc if we're
934 using the backup superblock/block group descriptors.
935 (ext2fs_descriptor_block_loc): If we're using the backup
936 superblock descriptors, use the backup descriptor block in
937 the next block group.
939 2002-10-30 Theodore Ts'o <tytso@mit.edu>
941 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
942 table so that it buts up against the bitmap blocks, to
943 avoid block fragmentation.
945 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
946 bug; only allocate group descriptor blocks up to
949 2002-10-25 Theodore Ts'o <tytso@mit.edu>
951 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
952 know when a filesystem was created. (Sometimes this can
955 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
957 2002-10-20 Theodore Ts'o <tytso@valinux.com>
959 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
960 the journal data mode.
962 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
963 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
964 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
965 the meta_blockgroup filesystem format.
967 2002-10-15 <tytso@snap.thunk.org>
969 * ext2_fs.h: Add new field in superblock for default mount options.
971 2002-10-13 Theodore Ts'o <tytso@mit.edu>
973 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
976 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
978 * rw_bitmaps.c (ext2fs_write_block_bitmap,
979 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
980 because the bitmap is getting written to disk. Make
981 ext2fs_swap_bitmap be a static function, since it's not
982 intended to be exported.
984 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
986 2001-09-24 Theodore Tso <tytso@mit.edu>
988 * Release of E2fsprogs 1.29
990 2001-08-31 Theodore Tso <tytso@thunk.org>
992 * Release of E2fsprogs 1.28
994 2002-08-31 Theodore Ts'o <tytso@valinux.com>
996 * dblist.c (ext2fs_dblist_sort): New function which allows the
997 caller to pass in a special sort comparison function.
999 2002-08-20 Theodore Ts'o <tytso@mit.edu>
1001 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
1002 failed to accurately characterize non-standard slow
1003 symlinks. (Which don't appear in practice on real-life
1004 systems, fortunately.)
1006 2002-08-17 Theodore Ts'o <tytso@mit.edu>
1008 * Makefile.in: Remove inode_io.o from the standard object files,
1009 and only build it if debugfs is enabled (it requires
1010 fileio.o, which is only built if --disable-debugfs isn't
1011 specified to configure).
1013 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
1014 incompatible way so that it is no longer
1015 endian-dependent. Add the TEA hash. Allow the seed
1016 parameter to be optional.
1018 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
1019 These features are all now in the HALF_MD4 hash. Add
1020 definition for EXT2_HASH_TEA.
1022 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
1023 a pointer instead of an array.
1025 2002-08-16 Theodore Ts'o <tytso@mit.edu>
1027 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
1029 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
1030 the number of data blocks used by an inode exclusive of
1033 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
1034 adjusts the reference count in an extended attribute block.
1036 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
1037 correctly deal with extended attribute blocks in symbolic
1040 2002-08-13 <tytso@snap.thunk.org>
1042 * Makefile.in: Move dupfs.o and test_io.o from the
1043 needed-by-debugfs object list to the needed-by-resizer
1044 object list. Fixes compile problem if the system is built
1045 with only --disable-debugfs.
1047 2002-07-29 Theodore Ts'o <tytso@mit.edu>
1049 * link.c (ext2fs_link): When adding a new link to a directory,
1050 clear the HTREE bit.
1052 2002-07-23 Theodore Ts'o <tytso@mit.edu>
1054 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
1055 calculations for names > 32 characters to be completely
1056 bogus. Changed MD4 calculation to match what is currently
1057 being used in the CVS gkernel tree.
1059 2002-07-19 Theodore Ts'o <tytso@mit.edu>
1061 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
1062 superblock definition.
1064 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
1065 create a set of u32_list functions.
1067 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
1068 since that's required by the directory indexing code.
1070 2002-07-14 Theodore Ts'o <tytso@mit.edu>
1072 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
1073 using a C++ reserved word.
1075 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
1076 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
1077 old version of glibc (built against 2.2 headers) will
1078 interact badly with the workaround to actually cause more
1079 problems. I hate it when the glibc folks think they're
1080 being smarter than the kernel....
1082 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
1084 * ext2_fs.h: Add superblock field for reserved group descriptors.
1086 2002-06-28 Theodore Ts'o <tytso@mit.edu>
1088 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
1089 ext2fs_cpu_to_{l,b}e{32,16}
1091 2002-06-27 Theodore Ts'o <tytso@mit.edu>
1093 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
1094 Add appropriate fallbacks in this case.
1096 2002-06-26 Theodore Ts'o <tytso@mit.edu>
1098 * dirhash.c (ext2fs_dirhash): Change function signature to support
1099 a hash seed, and to return the minor hash (for 64-bit hash
1100 support). Add support for the half MD4, half MD4 with
1101 seed, and half MD4 with seed and 64 bits.
1103 2002-06-15 Theodore Ts'o <tytso@mit.edu>
1105 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
1107 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
1109 * ext2_fs.h: Add macros for maximum block/inode counts:
1110 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
1111 and EXT2_MAX_INODES_PER_GROUP.
1113 * openfs.c (ext2fs_open): Check that the number of blocks in a group
1114 is less than 2^16, otherwise we need an INCOMPAT flag (not
1115 in existence yet, if ever) to open such a filesystem.
1117 * initialize.c (ext2fs_initialize): Limit the number of blocks and
1118 inodes in a group to less than 2^16.
1120 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
1122 * ext2_fs.h: Further minor cleanups of the header. Consolidate
1123 some checks for __KERNEL__ into one place.
1125 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
1127 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
1128 the EXT2_SB() macro instead. Remove kernel function
1129 prototypes also. This matches the 2.5 kernel, and
1130 is also cleaner for other reasons. Whitespace cleanup.
1132 2002-05-21 Theodore Ts'o <tytso@mit.edu>
1134 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
1136 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
1138 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
1140 * initialize.c (ext2fs_initialize): Remove assumption that
1141 blocksizes are always <= 4k.
1143 2002-05-11 Theodore Ts'o <tytso@mit.edu>
1145 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
1146 silently if inode pointer is NULL (and ext2fs_bmap is
1147 expected to read the inode itself).
1149 2002-04-27 Theodore Ts'o <tytso@mit.edu>
1151 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
1152 file we are checking is a block device file before looking
1153 at st_rdev, since it's not valid for normal files.
1154 (is_swap_device): Move so that it is outside the
1155 HAVE_MNTENT_H, so that it is always built.
1157 2002-03-11 Theodore Tso <tytso@mit.edu>
1159 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
1160 functions which take an extra flags argument. The flag
1161 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
1162 field is byte swampped on big-endian machines, since in
1163 the V2 structure, name_len is a char field which is
1164 doesn't need to be byte swapped --- except if an
1165 old-style kernel had byte-swapped the name_len field
1166 as part of the V1 structure.
1168 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
1170 * dirhash.c (ext2fs_dirhash): New function which calculates the
1171 hash for a filename in an indexed directory.
1173 2002-03-08 Theodore Tso <tytso@mit.edu>
1175 * Release of E2fsprogs 1.27
1177 2002-03-07 Theodore Tso <tytso@mit.edu>
1179 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
1181 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
1182 tst_byteswap.c: Fix gcc -Wall complaints
1184 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
1185 (From Philipp Thomas <pthomas@suse.de>)
1187 2002-02-25 Theodore Tso <tytso@mit.edu>
1189 * ext2_fs.h: Add structure definitions for the directory indexing
1192 2002-02-23 Theodore Tso <tytso@mit.edu>
1194 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
1195 it doesn't break things on mis32, sparc32, and alpha
1198 2002-02-21 Theodore Tso <tytso@mit.edu>
1200 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
1201 we were missing an fclose().
1203 2002-02-20 Theodore Tso <tytso@mit.edu>
1205 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
1206 abstraction interface which exports an ext2 inode.
1208 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
1209 as a public interface. Change void * to const void * in
1210 ext2fs_file_write's interface.
1212 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
1213 conditional; save a few bytes.
1215 2002-02-12 Theodore Tso <tytso@mit.edu>
1217 * Makefile.in (tst_badblocks): Add some extra .o files when
1218 linking the debugging program tst_badblocks which are
1219 needed if we aren't compiling with inline functions enable.
1221 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
1222 define away __inline__ since it may not be supported.
1224 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
1225 stripped down jbd_debug that doesn't use variadic
1226 arguments. This will cause warnings under AIX, but things
1229 2002-02-03 Theodore Tso <tytso@thunk.org>
1231 * Release of E2fsprogs 1.26
1233 2002-02-03 Theodore Tso <tytso@mit.edu>
1235 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
1236 so that the number of directories in use is adjusted
1239 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
1240 which optionally will modify the number of directories
1243 2002-01-03 Theodore Tso <tytso@mit.edu>
1245 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
1246 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
1247 which will return deleted directory entries.
1248 ext2fs_dir_iterate2 takes a new callback function which
1249 is identical with the one used by
1250 ext2fs_dblist_dir_iterate(). If the directory entry is
1251 deleted, the callback function will be called with the
1252 entry paraemter set to DIRENT_DELETED_FILE.
1254 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
1255 ext2fs_block_alloc_stats): New functions which update
1256 block/inode allocation statistics in the bitmaps, block
1257 group descriptors, and superblock.
1259 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
1260 expanddir.c (expand_dir_proc), bb_inode.c
1261 (clear_bad_block_proc, set_bad_block_proc,
1262 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
1263 Update to use new block/inode allocation statistics.
1265 2001-12-24 Theodore Tso <tytso@mit.edu>
1267 * ismounted.c (is_swap_device): New function used by
1268 ext2fs_check_if_mounted and ext2fs_check_mount_point which
1269 determines whether or not the specified device is a swap
1270 device by using /proc/swaps. More bulletproofing for
1271 idiotic/careless system administrators!
1273 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
1274 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
1275 field to struct_ext2_filsys, umask. This field is
1276 initialize to 022, and affects ext2fs_mkdir in the obvious
1277 way. (In the future umask should also affect new file
1278 creation routines, but the fileio functions don't
1279 currently support this yes.)
1281 * ismounted.c (check_mntent_file): Stat all of the entries in
1282 /etc/mtab and/or /proc/mounts in order to catch dim-witted
1283 system administrators who might have created alias
1286 2001-12-23 Theodore Tso <tytso@mit.edu>
1288 * Makefile.in, jfs_user.h: Move linux/jbd.h to
1289 ext2fs/kernel-jbd.h, to avoid using the system header
1290 file version of hbd.h when using diet glibc (since it
1291 forcibly adds /usr/include to the beginning of the
1292 include search path.)
1294 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
1295 include/linux directory.
1297 2001-12-16 Theodore Tso <tytso@mit.edu>
1299 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
1300 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
1301 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
1303 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
1306 2001-12-03 Theodore Tso <tytso@mit.edu>
1308 * unix_io.c (unix_open): Make sure the ulimit workaround works
1309 regardless of the version of glibc which is used to
1312 2001-11-26 Theodore Tso <tytso@mit.edu>
1314 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
1315 trying to unset the filesize limit if at all possible,
1316 if a block device is getting opened. (The filesize limit
1317 shouldn't be applied against writes to a block device, but
1318 starting in 2.4.10, the kernel is doing this.)
1320 2001-11-05 Theodore Tso <tytso@mit.edu>
1322 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
1323 file on adding a journal to an already-mounted filesystem,
1324 try to clear the ext2 file attributes on an already
1325 existing .journal file so that we don't fail if on a
1326 partially added journal to the filesystem.
1328 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
1329 which signals that a particular inode should not have the
1330 last bits of data (the "tail") be merged with another
1331 file. This is necessary to keep LILO happy.
1333 2001-09-20 Theodore Tso <tytso@thunk.org>
1335 * Release of E2fsprogs 1.25
1337 2001-09-16 Theodore Tso <tytso@mit.edu>
1339 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
1340 which was breaking the build on the Hurd. (Addresses
1341 Debian bug #112414).
1343 2001-09-13 Theodore Ts'o <tytso@mit.edu>
1345 * ismounted.c (check_mntent_file): We now validate the entry in
1346 /etc/mtab to make sure the filesystem is really mounted,
1347 since some broken distributions (read: Slackware) have
1348 buggy boot scripts that don't initialize /etc/mtab before
1349 checking non-root filesystems. (Slackware also doesn't
1350 check the root filesystem separately, and reboot if the
1351 root filesystem had changes applied to it, which is
1352 dangerous and broken.)
1354 2001-09-02 Theodore Tso <tytso@thunk.org>
1356 * Release of E2fsprogs 1.24a
1358 2001-08-30 Theodore Tso <tytso@thunk.org>
1360 * Release of E2fsprogs 1.24
1362 2001-08-30 Theodore Tso <tytso@valinux.com>
1364 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
1365 changes, since the ioctl number has been reused by another
1368 2001-08-15 Theodore Tso <tytso@valinux.com>
1370 * Release of E2fsprogs 1.23
1372 2001-08-05 Theodore Tso <tytso@valinux.com>
1374 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
1375 version of the bitmap test routines to speed up these
1376 routines. (At some point I may want to make these
1377 routines use the find_first_bit functions, but that will
1378 add a lot of complexity since it means that these
1379 functions will have to break the bitmap abstraction
1380 boundary. It's not clear it's worth it.)
1382 * mkjournal.c (mkjournal_proc): Remember the last block allocated
1383 to speed up ext2fs_new_block().
1385 2001-07-29 Theodore Tso <tytso@valinux.com>
1387 * finddev.c (scan_dir): Fix memory leak; we weren't calling
1388 closedir() when exiting the function in all cases.
1390 2001-07-27 Theodore Tso <tytso@valinux.com>
1392 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
1393 block usable in the journal for external journals to be 2
1394 or 3, depending on the blocksize, so that the existing
1395 kernel code does the right thing.
1397 * getsize.c (ext2fs_get_device_size): Add support for the
1398 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
1399 from Ben LaHaise, but it's likely this interface won't
1402 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1403 when writing the journal superblock, too. (Oops! Needed
1404 to make 1k filesystems with external journal to work.)
1406 2001-07-26 Theodore Tso <tytso@valinux.com>
1408 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1409 to find the journal superblock if the blocksize is 1024.
1411 2001-07-21 Theodore Tso <tytso@valinux.com>
1413 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
1415 2001-07-20 Theodore Tso <tytso@valinux.com>
1417 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
1418 attribute block, set the filesystem changed bit.
1420 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1421 Comment out these functions since we're not using them.
1423 2001-07-10 Theodore Tso <tytso@valinux.com>
1425 * closefs.c (write_primary_superblock): After writing changes to
1426 the primary superblock, update the original superblock
1427 copy so we don't have to re-write those changes in the
1429 (ext2fs_flush): Clear the superblock dirty flag after
1430 we've flushed out changes to disk.
1432 2001-07-07 Theodore Tso <tytso@valinux.com>
1434 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
1435 to avoid register conflicts when compiling in PIC mode.
1437 2001-07-04 Theodore Tso <tytso@valinux.com>
1439 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1440 Add new functions (C and in i386 assembler) which quickly
1441 find bits set in a bitmask.
1443 2001-06-23 Theodore Tso <tytso@valinux.com>
1445 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
1446 ext2_ext_attr.h and ext_attr.c for extended attributes
1449 * Release of E2fsprogs 1.22
1451 2001-06-22 Theodore Tso <tytso@valinux.com>
1453 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
1454 descriptor so that adding a journal to a mounted
1455 filesystem doesn't die. (Fixes a bug accidentally
1456 introduced in e2fsprogs 1.21.)
1458 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
1459 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
1460 fchflags without defining UF_NODUMP. (Addresses Debian
1463 * flushb.c: Use platform independent method of defining the
1464 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
1465 since on newer glibc's BLKFLSBUF is defined there.
1467 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
1468 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
1469 to support byte swapping even if we don't support the
1470 conversion functions. (Fixes Debian bug #101686).
1472 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
1473 since the byte-swapping code all assumes the
1474 ext2_dir_entry structure. (It's a question of whether or
1475 not name_len should be byte-swapped or not, and whether
1476 it's a 16 bit or 8 bit field.)
1478 2001-06-15 Theodore Tso <tytso@valinux.com>
1480 * Release of E2fsprogs 1.21
1482 2001-06-15 Theodore Tso <tytso@valinux.com>
1484 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
1485 file which is generated and is therefore found in the
1486 build directory, not source directory.
1488 * ismounted.c (check_mntent_file): Use a test file in / to check
1489 to see if the root filesystem is mounted read-only. This
1490 protects against the case where /etc might not be on /, as
1491 well as the case where /etc/mtab doesn't exist. (Both are
1492 should-never happen scenarios, but you never know...)
1494 2001-06-14 Theodore Tso <tytso@valinux.com>
1496 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
1497 Remove unneeded #pragma argsused, since the arguments are
1500 2001-06-13 Theodore Tso <tytso@valinux.com>
1502 * ext2_types.h.in: If linux/types.h has been defined, then don't
1503 try to redefine the typedefs.
1505 * Makefile.in (HFILES): Add ext2_types.h to the list of files
1506 which should be installed.
1508 * ismounted.c (check_mntent_file): Work around GNU hurd brain
1509 damage. Addresses Debian bug #100304.
1511 * Makefile.in: Limit some .o files from being included into the
1512 library if --disable-debugfs, --disable-swapfs,
1513 --disable-imager, or --disable-resizer are used.
1515 2001-06-12 Theodore Tso <tytso@valinux.com>
1517 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
1518 function, and use the ext2fs_badblocks_* functions
1521 2001-06-11 Theodore Tso <tytso@valinux.com>
1523 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
1524 ext2fs_mark_generic_bitmap and
1525 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
1526 functions. (This saves space and doesn't significantly
1527 change the speed of e2fsck on a P-III.)
1529 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
1530 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
1531 include the byte-swapping logic if ENABLE_SWAPFS is turned
1532 on or if we're on a big-endian machine.
1534 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
1535 set EXT2_FLAG_SWAP_BYTES, instead of using
1538 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
1539 autoconf to determine whether or not return
1540 EXT2_FLAG_SWAP_BYTES.
1542 2001-06-10 Theodore Tso <tytso@valinux.com>
1544 * Makefile.in: Remove the dependence on the libe2p library.
1546 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
1547 with direct usage of the ioctl/fchflags so that we don't
1548 have to depend on the libe2p library.
1550 2001-06-08 Theodore Tso <tytso@valinux.com>
1552 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
1553 when trying to find a 32-bit wide type.
1555 * icount.c (insert_icount_el): Fix the code used to estimate the
1556 size of the new icount array to be more intelligent, to
1557 avoid reallocating the array too many times. Thanks to
1558 Enrique Perez-Terron for pointing this out.
1560 2001-06-02 Theodore Tso <tytso@valinux.com>
1562 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
1563 for a symlink to determine whether it is a fast symlink.
1565 2001-06-01 Theodore Tso <tytso@valinux.com>
1567 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
1568 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
1570 2001-05-25 Theodore Tso <tytso@valinux.com>
1572 * Release of E2fsprogs 1.20
1574 2001-05-25 Theodore Tso <tytso@valinux.com>
1576 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
1577 some to clean up Andreas's patches. Use strncpy instead
1578 of strcpy to save the root's mountpoint. Clean up #ifdef
1579 structure. Remove uneeded variable in testing/debug driver.
1581 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
1583 * ismounted.c: Add check for root device which doesn't depend on
1584 /etc/fstab or /proc/mounts to be correct. Don't call
1585 endmntent() before we are done with mnt struct.
1587 2001-05-23 Theodore Tso <tytso@valinux.com>
1589 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
1592 2001-05-21 Theodore Tso <tytso@valinux.com>
1594 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
1595 make room for pre-existing usage of
1596 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
1597 the same codepoint as EXT2_BTREE_FL.
1599 2001-05-20 Theodore Tso <tytso@valinux.com>
1601 * ext2fs.h: #include <> instead of "" for ext2fs and et header
1602 files, since they will be installed in /usr/include
1604 2001-05-14 Theodore Tso <tytso@valinux.com>
1606 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,

1619 Adjust all files in this directroy to include this file.
1621 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
1624 2001-05-05 Theodore Tso <tytso@valinux.com>
1626 * fileio.c (ext2fs_file_read): Factored out common code and
1627 cleaned up function. Fixed a bug where if there was an
1628 error reading from the disk, the number of bytes read
1629 wasn't reliably set. (Fixes Debian bug #79163)
1630 (ext2fs_file_write): Factored out common code and made
1631 function more efficient; if writing a full block, don't
1632 bother to do a read-modify-write cycle.
1634 2001-05-04 Theodore Tso <tytso@valinux.com>
1636 * dirblock.c (ext2fs_read_dir_block): Check for an directory
1637 record length which isn't a multiple four, and treat that
1638 as an invalid. Scan the directory and return an error
1639 (EXT2_ET_DIR_CORRUPTED) if the directory records are
1641 (ext2fs_write_dir_block): If while byte-swapping the
1642 directory block, if there's an error, abort and return
1643 EXT2_ET_DIR_CORRUPTED.
1645 2001-05-02 Theodore Tso <tytso@valinux.com>
1647 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
1648 image_header field in the ext2_filsys structure
1650 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
1651 * inode.c (ext2fs_read_inode):
1652 * rw_bitmaps.c (read_bitmaps):
1653 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
1655 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
1656 sure the full bitmap is saved.
1658 2001-05-01 Theodore Tso <tytso@valinux.com>
1660 * e2image.h (struct ext2_image_hdr): Add space for the device name
1661 in the image header.
1663 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
1664 make sure the rec_len is a multiple of 4, to prevent
1665 bus-errors on architectures which care about mis-aligned
1668 2001-04-25 Theodore Tso <tytso@valinux.com>
1670 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
1671 query the device sizes using the BLKGETSIZE ioctl.
1673 2001-04-16 Theodore Tso <tytso@valinux.com>
1675 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
1676 before checking /etc/mtab. The EXT2_MF_READONLY flag is
1677 now set from the /etc/mtab options field for all
1678 filesystems, not just the root filesystem. Add debugging
1679 code to make it easier to test ext2fs_check_if_mounted().
1681 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
1682 check; return an error if there's an attempt to create a
1683 journal less than 1024 filesystem blocks.
1685 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
1686 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
1688 2001-02-20 Theodore Tso <tytso@valinux.com>
1690 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
1693 * tst_byteswap.c: New function to test the byteswap functions.
1694 Add to regression test suite.
1696 2001-02-08 Theodore Tso <tytso@valinux.com>
1698 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
1700 2001-02-07 Theodore Tso <tytso@valinux.com>
1702 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
1703 of s_first for external devices to always be 1, since
1704 jsb->s_first is always relative to the start of the
1705 journal superblock. Use htonl(1) when setting s_nr_users.
1707 2001-01-17 Theodore Ts'o <tytso@valinux.com>
1709 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
1710 device number of the filesystem (instead of the journal)
1711 was being dropped into s_journal_dev.
1713 2001-01-15 Theodore Ts'o <tytso@valinux.com>
1715 * initialize.c (ext2fs_initialize): Add support for initializing
1716 the ext2 superblock for external journal devices. This
1717 basically means we don't bother to allocate any block
1720 * openfs.c (ext2fs_open): Only open external journal devices if
1721 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
1722 ext2fs_open. When opening such devices, don't try to read
1723 the block group descriptors, since they're not there.
1725 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
1727 * mkjournal.c: Export a new function,
1728 ext2fs_create_journal_superblock(), which allocates and
1729 returns a buffer containing a journal superblock. This is
1730 needed by mke2fs to create an external journal. Rewrote
1731 ext2fs_add_journal_device() so that it no longer creates
1732 the external journal, but rather adds a filesystem to an
1733 existing external journal. It handles all of the UUID
1736 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
1737 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
1738 Changed function prototype for ext2fs_add_journal_device().
1740 2001-01-14 Theodore Ts'o <tytso@valinux.com>
1742 * closefs.c (ext2fs_flush): Don't write out anything beyond the
1743 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
1746 2001-01-12 Theodore Ts'o <tytso@valinux.com>
1748 * imager.c: Fix gcc -Wall complaints and a series of bugs where
1749 retval wasn't set correctly. (Thanks to Andreas Dilger
1750 for pointing this out.)
1752 2001-01-11 <tytso@snap.thunk.org>
1754 * flushb.c (ext2fs_sync_device): New function which centralizes
1755 all of the places which might try to use the BLKFLSBUF
1756 or FDFLUSH ioctls (and usually failing to define them
1757 since the system header files don't usually do this for
1758 us, and we're trying to avoid usage of kernel include
1761 2001-01-10 <tytso@snap.thunk.org>
1763 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
1764 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,

1768 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
1769 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
1770 ext2_ino_t, to protect applications that attempt to
1771 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
1772 changes ino_t(!?). So we use ext2_ino_t to avoid an
1773 unexpected ABI change.
1775 2001-01-05 <tytso@snap.thunk.org>
1777 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
1778 we may overrun allocated memory in case of a corrupted
1779 filesystem (or an e2fsck test case :-) when byte-swapping
1780 the directory block.
1782 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
1784 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
1785 complaints including a missing return 0 at the end of
1786 ext2fs_add_journal_device.
1788 2001-01-03 <tytso@snap.thunk.org>
1790 * Makefile.in: Link in libe2p when creating libext2fs as a shared
1791 library, since mkjournal.c now references fsetflags().
1793 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
1794 Dilger's changes (with fixups) to allow on-line creation
1797 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
1798 EXT2_FLAG_SUPER_ONLY, which the close routines to only
1799 update the superblock, and not the group descriptors.
1801 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
1803 * ismounted.c: add ext2fs_check_mount_point() function, which will
1804 optionally return the mount point of a device if mounted
1806 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
1808 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
1809 ext2fs_add_journal_inode()
1811 2001-01-01 <tytso@snap.thunk.org>
1813 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
1814 source (but not binary) compatibility of some users of the
1815 ext2 library. They should just simply do a global search
1816 and replace of struct ext2fs_sb with struct
1817 ext2_super_block, and use their own private copy of
1818 ext2_fs.h if they aren't already.
1820 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
1821 Replace use of ext2fs_sb with ext2_super_block.
1823 2000-12-31 <tytso@snap.thunk.org>
1825 * ext2fs.h: Cleaned up header file by removing definitions of
1826 feature flags that might not have been defined in older
1827 ext2 header files. Now that we're using our own
1828 include/linux/ext2fs.h header file, this can never happen.
1830 * jfs_dat.h: Removed old header file which is no longer needed.
1832 2000-12-13 Theodore Ts'o <tytso@valinux.com>
1834 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
1835 by Andreas Dilger to update the filesystem revision to
1838 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
1841 2000-12-09 <tytso@snap.thunk.org>
1843 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
1844 ext2fs_add_journal_device): Add a new argument to the APIs
1845 of these function, which is a flags word. This is used to
1846 allow the creation of a V1 superblock for those folks who
1847 are using ext3 0.3b in production. Note, the user-land
1848 interface for getting at this flag won't be documented, as
1849 the V1 superblock is deprecated.
1851 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
1852 which creates a V2 superblock instead of a V1 superblock.
1854 2000-11-21 <tytso@snap.thunk.org>
1856 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
1857 out by Andreas Dilger.
1859 2000-11-05 <tytso@snap.thunk.org>
1861 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
1862 ext2_fs.h, Makefile.in: New file that has routines that
1863 save ext2fs metadata to a file.
1865 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
1867 * e2image.h: New file which defines the file format for the ext2
1868 image file. (Saved copy of ext2 metadata to a file as a
1869 saving throw against worst-case damage.)
1871 2000-11-01 <tytso@snap.thunk.org>
1873 * inode.c (ext2fs_flush_icache): Add new function
1874 ext2fs_flush_icache() which flushes the internal inode
1875 cache. Applications which modify the inode table blocks
1876 directly must call this function.
1878 2000-10-26 <tytso@snap.thunk.org>
1880 * mkjournal.c: Add #include of netinet/in.h, since Solaris
1881 requires it for ntohl().
1883 * ext2_io.h (io_channel_write_byte): Add new interface to allow
1884 callers to write specific byte ranges. This is an
1885 optional interface, which not all IO channels may
1888 * unix_io.c (unix_write_byte):
1889 * test_io.c (test_write_byte): Add implementation of the
1890 write_byte function.
1892 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
1893 function which writes the primary superblock. If the IO
1894 channel supports writing raw bytes directly, only fields
1895 which were modified are written to the disk. This makes
1896 it safe(r) to use utilities like tune2fs on a mounted
1899 * freefs.c (ext2fs_free): Free the original superblock if it is
1902 * openfs.c (ext2fs_open): Store a copy of the original superblock
1905 * ext2fs.h: Add a field to store the original superblock in the
1906 ext2 context structure.
1908 2000-10-24 <tytso@snap.thunk.org>
1910 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
1911 don't need to use llseek).
1913 2000-10-24 <tytso@valinux.com>
1915 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
1916 creating an ext3 journal on a filesystem.
1918 2000-08-21 <tytso@valinux.com>
1920 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
1922 2000-08-22 <tytso@valinux.com>
1924 * unix_io.c: Make massive changes to support a multiple block
1925 writethrough cacheing.
1927 * ext2_io.h: Added flags field to the io_channel structure.
1929 2000-08-19 <tytso@valinux.com>
1931 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
1932 provides the function ext2fs_find_block_device(). This
1933 function returns the pathname to a block device, given its
1936 2000-07-13 <tytso@valinux.com>
1938 * Release of E2fsprogs 1.19
1940 2000-07-07 Theodore Ts'o <tytso@valinux.com>
1942 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
1943 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
1944 list of filesystem flags supported by the library.
1946 2000-07-04 Theodore Ts'o <tytso@valinux.com>
1948 * ext2fs.h: Update to include latest journalling additions to the
1951 * dll/jump.funcs: Add new jumptable entries for
1952 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1953 ext2fs_badblocks_equal.
1955 * tst_badblocks.c: Update test program to test
1956 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
1958 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
1959 writes out bad blocks list to a file.
1961 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
1962 changes the callback function to take two additional
1963 arguments; a private blind pointer supplied by the caller,
1964 and pointer to a char * containing a pointer to the
1967 * badblocks.c (ext2fs_badblocks_equal): Add new function which
1968 returns true if two badblocks list are equal.
1970 * Makefile.in: Remove explicit link of -lc in the shared library.
1971 (It shouldn't be necessary, and is harmful in some cases).
1973 2000-06-10 Theodore Ts'o <tytso@valinux.com>
1975 * getsize.c (main): Add debugging code under #ifdef DEBUG
1977 2000-05-27 Theodore Ts'o <tytso@valinux.com>
1979 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
1980 earlier, so that if there's an error reading it, we can
1981 more cleanly back out of the operation.
1983 2000-05-25 <tytso@snap.thunk.org>
1985 * getsize.c (ext2fs_get_device_size): Use open64() instead of
1986 open() if it exists. Under linux, manually define the
1987 ioctl for BLKGETSIZE if it isn't already defined and it's
1990 * unix_io.c (unix_open): Use open64() instead of open() if it
1993 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1994 available (and prototypes are defined) use it in
1995 preference to llseek.
1997 * Makefile: Add hack dependency rule so that parallel makes work
2000 2000-05-18 Theodore Ts'o <tytso@valinux.com>
2002 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
2004 2000-04-03 Theodore Ts'o <tytso@valinux.com>
2006 * block.c: Readibility tweak in conditionals involving
2009 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
2010 how to define __s64 and __u64. Turn off "compression is
2011 experimental" warning if the cpp macro
2012 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
2014 2000-02-11 <tytso@snap.thunk.org>
2016 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
2017 Conditionally include Compression as a supported type if
2018 ENABLE_COMPRESSION (via --enable-compression) is turned on.
2020 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
2022 2000-02-08 <tytso@snap.thunk.org>
2024 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
2025 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2026 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
2027 Change to return the previous state of the bit that is
2028 being marked or unmarked. For speed optimization.
2030 2000-02-02 Theodore Ts'o <tytso@valinux.com>
2032 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
2034 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
2035 needed any more; we know it will always be i_generation.
2036 Add support for swapping the high bits of the uid and gid.
2038 1999-11-19 <tytso@valinux.com>
2040 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
2041 counts if the link was successful. Patch suggested by
2044 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
2045 the source directory.
2047 1999-11-10 <tytso@valinux.com>
2049 * Release of E2fsprogs 1.18
2051 1999-11-08 <tytso@valinux.com>
2053 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
2054 since ext2fs_badblocks_list_free was moved to freefs.c.
2056 * tst_badblocks.c: Use the newer badblocks API names. Add
2057 duplicate blocks to the test inputs to test dealing with
2058 adding blocks which are already in the badblocks list.
2060 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
2061 of the list, use a shortcut O(1) operations instead of an
2062 O(n) operation. (Idea suggested by David Beattie.)
2064 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
2065 of badblocks_list_free(), to save a procedure call.
2067 1999-10-26 <tytso@valinux.com>
2069 * Release of E2fsprogs 1.17
2071 1999-10-26 <tytso@valinux.com>
2073 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
2074 seem to handle ~0UL the same way as they used to.
2076 1999-10-25 <tytso@valinux.com>
2078 * nt_io.c (_OpenNtName): Open the device using
2079 FILE_SYNCHRONOUS_IO_NONALERT instead of
2080 FILE_SYNCHRONOUS_IO_ALERT
2081 (nt_open): At the end of the device open routine, unlock
2082 the drive but do not dismount it.
2084 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
2087 1999-10-22 <tytso@valinux.com>
2089 * Release of E2fsprogs 1.16
2091 1999-10-22 <tytso@valinux.com>
2093 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
2095 * link.c (ext2fs_link): This call now uses the low three bits of
2096 the flags parameter to pass the directory filetype
2097 information; it will set the directory entry FILETYPE
2098 information if the filesystem supports it.
2100 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
2101 option is set, then create the '.' and '..' entries with
2102 the filetype set to EXT2_FT_DIR.
2104 1999-09-24 <tytso@valinux.com>
2106 * nt_io.c: New file which supports I/O under Windows NT.
2108 1999-09-07 <tytso@valinux.com>
2110 * ext2fs.h: Add new fields for journalling and define new
2111 feature bits used by newer filesystems: IMAGIC_INODES,
2112 HAS_JOURNAL, RECOVER.
2114 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
2115 we update the inode block count and size files so that the
2116 block count field is updated correctly when we create an
2119 1999-07-18 Theodore Ts'o <tytso@valinux.com>
2121 * Release of E2fsprogs 1.15
2123 1999-06-23 <tytso@valinux.com>
2125 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
2126 kernels that use i_generation instead of i_version. Patch
2127 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
2129 1999-06-21 <tytso@valinux.com>
2131 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
2132 directory entry before calling the callback function.
2133 This should prevent some core dumps of insufficiently
2134 paranoid callback functions.
2136 1999-05-29 <tytso@rsts-11.mit.edu>
2138 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
2140 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
2141 that we don't handle writing yet (we do). Fixed bug where
2142 we weren't allocating a big enough buffer for ext2_bmap.
2144 1999-05-03 <tytso@rsts-11.mit.edu>
2146 * openfs.c (ext2fs_open): Check to make sure that the number of
2147 blocks per group is not zero --- if so, it must be a bad
2150 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2152 * Release of E2fsprogs 1.14

2156 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
2157 the inode number is zero; if it's zero, return
2158 EXT2_ET_BAD_INODE_NUM.
2160 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2162 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
2163 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
2166 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
2168 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
2169 non-Linux case to use EINVAL by default, unless it isn't
2170 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
2173 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
2175 * Release of E2fsprogs 1.13
2177 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
2179 * Makefile.in: Updated dependencies.
2181 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
2183 * initialize.c (ext2fs_initialize): Make sure that we allocate
2184 enough inodes so that we can make a valid filesystem.
2186 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
2188 * rw_bitmaps.c: Fixed signed/unsigned warnings.
2190 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
2191 function declaration.
2193 * dblist.c (make_dblist): Add safety check in case the dblist
2194 pointer passed in is null (in which case, assign it to
2195 fs->dblist). Fixed some signed/unsigned warnings.
2197 * bmap.c: Make addr_per_block be of type blk_t to avoid
2198 signed/unsigned warnings.
2200 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
2201 function declaration.
2203 * get_pathname.c (get_pathname_proc): Use return value from
2204 ext2fs_get_mem, instead of checking if &gp->name is
2207 * dir_iterate.c (ext2fs_process_dir_block):
2208 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
2209 from the function declaration.
2211 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
2212 return the error directly instead of jumping to the
2213 cleanup routine, since we don't need to do any cleanup.
2215 * alloc_table.c (ext2fs_allocate_group_table): Make this
2216 function take a dgrp_t for its group argument.
2218 * ext2fs.h: Make dgrp_t an __u32 type, and make
2219 fs->desc_group_count be of type dgrp_t.
2221 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
2223 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
2224 than 10 blocks when we need to expand the size of the
2227 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2229 * Release of E2fsprogs 1.12
2231 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2233 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
2234 appropriate for all of the block group copies, so that
2235 it's clear where the beginning of the filesystem is on the
2236 disk. (For when the partition table gets scrod.)
2238 * ext2fs.h: Change the name of the feature from
2239 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
2240 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
2242 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
2244 * inode.c (get_next_blockgroup): Fix bug where if
2245 get_next_blockgroup() is called early because of a missing
2246 inode table in a block group, the current_inode counter
2247 wasn't incremented correctly.
2249 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
2251 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
2252 against a completely trashed bad block inode.
2254 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
2256 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
2257 the stride length hits a bad value, we retry the block
2258 allocation starting at the beginning of the block group.
2260 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
2261 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
2262 e2_blkcnt_t to avoid collision with LFS API.
2264 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
2266 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
2267 way that avoids overflows on disk sizes greater than 4GB.
2269 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
2271 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
2272 return type for comparison functions for qsort.
2274 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
2277 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
2279 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
2282 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
2283 evade a potential problem with glibc's header files trying
2284 to spike out linux/types.h.
2286 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
2287 include the old size of the memory, which is needed for
2288 some braindamaged memory allocation systems that don't
2291 * badblocks.c (ext2fs_badblocks_list_add):
2292 bb_inode.c (clear_bad_block_proc):

2296 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
2297 pass the old size of the memory to be resized to
2298 ext2fs_resize_mem().
2300 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2302 * Makefile.in: Change to use new installation directory variables
2303 convention. Fix uninstall rules to take $(DESTDIR) into
2306 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
2308 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
2309 with 32 bit longs, then we need to manually define __s64
2310 and __u64, since the current kernel header files don't
2311 define these if __STRICT_ANSI__ is defined. This is a
2312 problem if we are compiling with full GCC warnings, since
2313 we do need 64 bit support.
2315 * Makefile.in (OBJS): Remove bmove.o from files to be built,
2316 since we're not using ext2fs_move_blocks() and there
2317 is some question as to its usefulness in its current
2320 * bmap.c (block_bmap): Remove unused function.
2322 * bmove.c (process_block): Fix -Wall warning.
2324 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
2326 * block.c (ext2fs_block_iterate3): Make the ref_offset field
2327 contain the offset into the inode.i_blocks array when
2328 ref_block is zero. Since we haven't done a formal
2329 release of e2fsprogs since block_iterate2 was first
2330 introduced, I removed block_iterate2, and renamed
2331 block_iterate3 to be block_iterate2.
2333 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
2334 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
2335 use of block_iterate and block_iterate2 to
2336 block_iterate2 with the new prototype for the
2337 interator function. (using blkcnt_t forr blockcount)
2339 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
2341 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
2342 s_prealloc_blocks, s_prealloc_dir_blocks). Added
2343 conditional defines of new features COMPAT_DIR_PREALLOC,
2344 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
2345 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
2346 the library to declare that we support COMPAT_DIR_PREALLOC,
2347 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
2349 * fileio.c: Rename function ext2fs_file_llseek to be
2350 ext2fs_file_lseek, which is more accurate.
2352 * block.c: Add new function ext2fs_block_iterate3 which calls
2353 the iterator function with the blockcount argument of
2354 type blkcnt_t. This version of the function is
2355 allowed to handle large files; the other fucntions are
2358 * ext2fs.h: Add new type blkcnt_t
2360 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
2362 * block.c (ext2fs_block_iterate2): Fix bug where the block count
2363 field wasn't getting correctly incremented for sparse
2364 files when the indirect or doubly-indirect block
2365 specified in the inode was zero.
2367 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2369 * unlink.c (unlink_proc):
2370 * lookup.c (lookup_proc):
2371 * link.c (link_proc):
2372 * get_pathname.c (get_pathname_proc):
2373 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
2374 from dirent->name_len, so it can be used for other
2377 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
2378 and indicate that we have support for this incompatible
2381 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2383 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
2385 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2387 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
2388 number of directories when the block group information is
2391 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
2393 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
2394 inode table is missing so that we catch the case where the
2395 first block group is missing.
2397 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
2400 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2402 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
2404 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
2406 * test_io.c (test_flush): Add a debugging printf when the flush
2409 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
2410 read in, return right away.
2412 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2414 * bitops.h: Don't try to do i386 inline asm functions if the
2417 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
2418 instead of linux/types.h, and e2_bitops.h instead of
2421 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
2424 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2426 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
2427 so that we don't need to call get_next_blockgroup() the
2428 first time around. Saves a bit of time, and prevents us
2429 from needing to assign -1 to current_group (which is an
2432 * icount.c (insert_icount_el): Cast the estimated number of inodes
2433 from a float to an ino_t.
2435 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
2436 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

2445 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
2446 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
2447 defined, then assume all of the
2448 ext2-specific header files are in a flat directory.
2450 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
2451 all assignments from void * to be compatible with C++.
2453 Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2455 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
2456 make sure the contents of the disk are flushed to disk.
2458 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2460 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
2461 avoid C++ namespace clash.
2463 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
2464 avoid C++ namespace clash.
2466 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
2467 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
2468 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
2469 unlink.c: Change private to be priv_data (to avoid C++
2472 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2474 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
2475 paranoid about validating the directory counts from the
2476 block group information.
2478 * all files: Don't include stdlib.h anymore; include it in
2479 ext2_fs.h, since that file requires stdlib.h
2481 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2483 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
2484 bitmap is loaded, and return an error if it is not.
2485 (expand_dir_proc): Only use ext2fs_write_dir_block when
2486 writing a directory block, not when writing out a fresh

2513 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2515 * [all files, basically]: Added definition of ext2fs_get_mem,
2516 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
2517 changed all library routines to use these wrapper functions.

2560 * Rename io.h to be ext2_io.h (avoid namespace collisions)
2562 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H

2568 * icount.c (ext2fs_icount_validate):
2569 * bmove.c (process_block): Fix lint error in type for fprintf().
2571 Mon Sep 15 11:45:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2573 * inode.c (ext2fs_check_directory): Add support for the callback
2574 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
2576 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2578 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
2579 padding of the bitmap to be all one's.
2581 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
2583 * llseek.c: Added missing semicolon to glibc fixup declaration of

2600 * io.h: Change the prototype of ext2fs_llseek() to use int's
2601 instead of unsigned int's.
2603 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
2604 to make life easer for GNU Libc 2.
2606 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
2607 filesystem has its bitmaps stored as 32-bit words with bit
2608 0 as the LSB of each word. Thus a bitmap with only bit 0
2609 set would be, as a string of bytes, 00 00 00 01 00 ... To
2610 cope with this, we byte-reverse each word of a bitmap if
2611 we have a big-endian filesystem, that is, if we are *not*
2612 byte-swapping other word-sized numbers.
2614 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

2632 and size_t where appropriate.
2634 * closefs.c (ext2fs_flush): Use dgrp_t instead of int where
2637 * openfs.c (ext2fs_open):
2638 * check_desc.c (ext2fs_check_desc): Use blk_t instead of int where

2645 * brel_ma.c: Fix to make be 16-bit safe.
2647 * link.c (ext2fs_link):

2681 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2683 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
2684 is zero, then return EXT2_IO_LLSEEK_FAILED.
2686 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
2688 * Release of E2fsprogs 1.11
2690 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2692 * dblist.c (ext2fs_dblist_count): Added new function which returns
2693 the number of directory blocks in dblist.
2695 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2697 * unix_io.c (unix_flush): Make the io_channel flush function do a
2698 fsync to flush the kernel buffers to disk.
2700 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2702 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
2703 current inode number wasn't being set by the
2704 goto_blockgroup function.
2706 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2708 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
2709 of blocks which need to be moved, and moves those blocks
2710 to another location in the filesystem.
2712 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
2713 bitmap, make sure all of the new parts of the bitmap are
2716 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2718 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
2719 wasn't being returned to the caller.
2721 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
2722 ext2fs_allocate_group_table() which sets the group tables
2723 for a particular block group. The relevant code was
2724 factored out of ext2fs_allocate_tables().
2726 * dblist.c (make_dblist): Adjust the initial size of the directory
2727 block list to be a bit more realistic (ten plus twice the
2728 number of directories in the filesystem).
2730 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2732 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
2733 ext2fs_badblocks_list_test would test the list (and exceed
2734 array boundaries) if there were no bad blocks on the bad
2735 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
2737 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2739 * Release of E2fsprogs version 1.10
2741 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2743 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
2744 inode and block bitmaps based on the RAID 0 stride
2745 parameter (which is passed by mke2fs).
2747 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
2748 mke2fs to communicate the stride length to
2749 ext2fs_allocate_tables()
2751 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
2753 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
2754 systems. (We can't assume that the new filesystem types
2757 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2759 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
2760 allocate the inode and block bitmaps inside block group at
2763 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2765 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
2766 filesystem has no free blocks, ext2fs_new_block would loop
2769 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
2771 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
2772 free if refcount goes to zero.

2788 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
2790 (unix_close, test_close): Decrement the refcount and only
2791 close the io_channel if the refcount goes to 0.
2793 * io.h: Add refcount to the io_channel structure. Add new macro
2794 interface io_channel_bumpcount() to bump the refcount.
2796 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2798 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
2799 cache in the filesystem handle, instead of the inode cache
2800 in a static variable.
2802 * freefs.c: Added static function to free the inode cache (called by
2805 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
2807 * ext2fs.h: Added pointer to the inode_cache structure.
2809 * block.c (block_iterate_ind, block_iterate_dind,

2811 doubly indirect, or triply indirect blocks, increment the
2812 block count field automatically.
2814 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2816 * Release of E2fsprogs version 1.09
2818 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2820 * version.c (ext2fs_parse_version_string): Check the passed in
2821 version string (instead of the hard-coded one).
2823 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
2824 greater filesystem size, clamp it to prevent allocating a
2825 block or inode bitmap beyond the filesystem.
2827 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
2828 overhead calculation was accidentally removed.
2830 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2832 * Release of E2fsprogs version 1.08
2834 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2836 * dblist.c (ext2fs_set_dir_block): New function which sets the
2837 block of a dblist entry, given the directory inode and
2840 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2842 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
2843 inode bitmaps at staggered locations across the block
2844 groups, to avoid concentrating the bitmaps on a small
2845 number of disks when using striped RAID arrays.
2847 * initialize.c (ext2fs_initialize): By default, choose the maximum
2848 possible number of blocks per group (based on the size of
2849 the bitmaps in the blocksize).
2851 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2853 * initialize.c (ext2fs_initialize): Add support for
2854 EXT2_COMPAT_SPARSE_SUPER feature.
2856 * closefs.c (ext2fs_bg_has_super): New function to determine
2857 whether or a particular block group should have a
2858 superblock and block group descriptor. Used for the
2859 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
2860 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
2861 or not the superblock should be written out for the block
2864 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
2865 for sparse duplicate superblocks.
2867 * version.c (ext2fs_get_library_version): New function which
2868 returns the library version.
2870 * version.c (ext2fs_parse_version_string): New function which
2871 parses a version string and returns a version number,
2872 so application programs can compare version numbers as
2875 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2877 * icount.c (ext2fs_create_icount): Change function so that it also
2878 takes a new argument which contains a "hint" icount
2879 structure. This "hint" icount allows the create function
2880 to set up the sorted list in advance. This reduces
2881 significantly the amount of data moving needed to insert
2882 these inodes into the list later.
2884 * icount.c (ext2fs_icount_validate): New function which validates
2885 that the icount structure's rep invariant.
2887 * icount.c (get_icount_el): Completely revamped implementation
2888 to subsume put_icount_el(). Put_icount_el() used to
2889 use an O(N) implementation to insert in the middle
2890 of the icount list. It now uses a O(ln N) to search
2891 for where the icount should be inserted, and then uses
2892 a memcpy to move the list down (instead of a for loop).
2894 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
2895 ext2fs_icount_increment, ext2fs_icount_decrement): Check
2896 to see if the inode is within bounds; if it isn't, return
2899 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
2900 when a bad inode number is passed to test_generic_bitmap
2901 to be EXT2FS_TEST_ERROR instead of the wrong
2902 EXT2FS_UNMARK_ERROR.
2904 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
2906 * Release of E2fsprogs version 1.07
2908 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2910 * Makefile.in (ELF_VERSION): Change version to be 2.2
2912 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2914 * alloc.c (ext2fs_get_free_blocks): Change routine to use
2915 ext2fs_fast_test_block_bitmap_range().
2917 * bitops.h (ext2fs_fast_test_block_bitmap_range,
2918 ext2fs_test_block_bitmap_range: New inline functions which
2919 test to see whether a contiguous range of blocks is
2922 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2924 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
2925 use ext2fs_badblocks_* instead of badblocks_*
2927 * bb_compat.c: New file which translates between old badblocks_*()
2928 names to ext2fs_badblocks_*()
2930 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
2931 link.c (since e2fsck doesn't use ext2fs_unlink()).
2933 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
2934 bitmap resizing routine moved from bitmaps.c, since e2fsck
2935 doesn't need to use this function.
2937 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
2938 since e2fsck only needs ext2fs_lookup.
2940 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2942 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
2943 already set; this is needed so that programs like dump
2944 which use the inode scan functions will deal with
2945 filesystems that have bad blocks in the inode table.
2947 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2949 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
2950 Moved to ext2fsP.h, since it doesn't need to be part of
2951 the public interface.
2953 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
2955 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2957 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
2958 directory block list abstraction. (Code moved from
2961 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
2962 to inode.c (since no one else should be peeking inside it!)
2964 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
2966 * openfs.c (ext2fs_open): Check the feature set in the ext2
2967 superblock, and refuse to open filesystems if they contain
2968 incompatible features. (Can be overriden with the
2971 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2973 * block.c (ext2fs_block_iterate2): Added new function
2974 ext2fs_block_iterate2 which changes the function
2975 signature of the callback function to include the
2976 referencing block and offset.
2978 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
2979 ext2fs_inode_scan_goto_blockgroup which allows an
2980 application to jump to a particular block group while
2981 doing an inode scan.
2983 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2985 * dirblock.c: Include string.h, since we use memcpy().
2987 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2989 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2990 a long not an int; this doesn't matter on i386 machines,
2991 but it does on Alpha's.
2993 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2995 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2996 table pointer is NULL, then return an error indicating
2997 that the inode table is missing.
2998 (get_next_blockgroup, get_next_blocks,
2999 ext2fs_get_next_inode): Don't treat a missing inode table
3000 as permanent error. Return MISSING_INODE_TABLE, but as an
3001 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
3003 * rw_bitmaps.c (ext2fs_write_block_bitmap,
3004 ext2fs_write_inode_bitmap): If the inode or block bitmap
3005 block is zero, then don't write out the inode or block
3006 bitmap. The idea here is to avoid stomping on the
3008 (read_bitmaps): If the inode or block bitmap block is
3009 zero, then fill in that portion of the inode or block
3010 bitmap with all zeros.
3012 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
3013 blocks in inode table when the inode table size is
3014 non-standard (and can therefore span blocks).
3016 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3018 * alloc.c (ext2fs_new_block): Fix fencepost error in
3019 ext2fs_new_block; make sure we don't try to allocate the
3020 first block beyond the end of the filesystem.
3022 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3024 * inode.c (check_for_inode_bad_blocks): New function called by
3025 get_next_blocks() to avoid reading in bad blocks marked in
3026 fs->badblocks. Inodes located in bad blocks are returned
3027 by ext2fs_get_next_inode() returns the error code
3028 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
3030 * alloc_tables.c (ext2fs_allocate_tables): New function which
3031 performs the part of mke2fs's job of allocating the
3034 * test_io.c (test_close): IO manager which is used for testing
3037 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3039 * inode.c (ext2fs_get_next_inode): Separate out the function of
3040 setting up for a new block group to get_next_blockgroup().
3041 Separate out the function of reading in blocks of the
3042 inode table to get_next_blocks().
3044 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
3046 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
3047 blocks to the badblock list in sorted order. This allows
3048 badblocks_list_test to be coded using a binary search for
3051 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3053 * Release of E2fsprogs version 1.06
3055 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3057 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
3058 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
3061 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
3062 set, then only write out the master superblock.
3064 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3066 * block.c (ext2fs_block_iterate): Fixed bug which caused
3067 block_iterate to fail to handle HURD created filesystems;
3068 it tested the inode translator field before the inode was
3071 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3073 * initialize.c (ext2fs_initialize): Make sure the description for
3074 the inode bitmap is set correctly.
3076 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

3082 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3084 * initialize.c: Override the kernel's idea of default
3085 checkinterval from 0 (never) to 180 days.

3094 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
3095 for shortcut function fs->read_inode() and fs->write_inode().
3096 Added inode_cache to reduce CPU time spent in doing
3099 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
3102 * namei.c (ext2fs_follow_link): New function.
3103 (ext2fs_namei): Extended to have support for chasing
3104 symbolic links. ext2fs_namei() still returns an inode
3105 which is a symbolic link. Symbolic links are only chased
3106 while resolving the containing directory. To chase
3107 symbolic links of the final result, use
3108 ext2fs_follow_link().
3110 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3112 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
3114 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
3115 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

3119 * initialize.c (ext2fs_initialize): On systems where the byte
3120 order is not i386 compatible, set the swap_byte flag.
3122 * inode.c (inocpy_with_swap): Check to see if inode contains a
3123 fast symlink before swapping the inode block fields. This
3124 required adding a new argument to inocpy_with_swap to
3125 determine whether the mode field is in host order or not.
3127 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3129 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
3130 the sparc, if EXT2_STD_BITOPS set, use the standard
3131 i386-compatible bitmask operations, instead on the
3132 non-standard native bitmask operators.
3134 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3136 * block.c (ext2fs_block_iterate): Cause block iterator to return
3137 the HURD translator block (along with everything else).
3138 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
3139 iterator, then don't return any meta data blocks
3140 (including the HURD translator).
3142 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3144 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
3146 * uuid.c: New file, containing UUID utility functions.
3148 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

3156 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3158 * openfs.c (ext2fs_open): If the blocksize in the superblock is
3159 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
3160 that's a basic value that must be correct for the rest of
3161 the library to work.
3163 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
3166 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

3202 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
3204 * getsize.c (ext2fs_get_device_size): Open the device read-only
3205 when trying to determine its size.
3207 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
3209 * Release of E2fsprogs version 1.02

3214 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3215 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3216 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
3217 to avoid conflicts with with kernel include files. Also
3218 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
3221 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
3223 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
3225 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
3226 s_def_resuid and s_def_resgid for backwards compatibility.
3228 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

3237 * closefs.c: #include <string.h> to pick up memset() declaration
3239 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
3241 * Makefile.in: Added support for BSD shared libraries.
3243 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
3246 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
3248 * unix_io.c (unix_open): Add a double check; if the passed in name
3249 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
3251 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
3253 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

3275 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
3276 Move these functions to freefs.c.
3278 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
3279 descriptors shadow memory to keep purify quiet. (This
3280 also has the nice benefit that the unused portion of the
3281 shadow descriptors are zeroed out.)
3283 * dirblock.c (ext2fs_write_dir_block): We need to use
3284 dirent->rec_len *before* it's byteswapped to find the
3285 location of the next directory structure!
3287 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
3288 cause ext2fs_new_inode to loop infinitely if we're trying
3289 to allocate an inode in group #0 and there are no free
3290 inodes at all in the system.
3292 * closefs.c: #include <errno.h> if it exists.
3294 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3296 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

3302 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
3303 installation directories correctly.
3305 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
3307 * namei.c (process_dir_block):
3308 * mkdir.c (ext2fs_mkdir):

3310 to read/write the directory block.
3312 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
3313 file containing functions for reading and writing
3314 directory blocks (byte swapping if necesssary)
3316 * block.c (block_iterate_ind, block_iterate_dind,
3317 block_iterate_tind): Byte swap the block addresses if
3318 EXT2_SWAP_BYTES is set (and swap them back before writing
3321 * inode.c (inocpy_with_swap): New function.
3322 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
3323 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
3325 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
3326 the superblock and group descriptors before writing it out.
3328 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
3329 then set the EXT2_SWAP_BYTES and byte-swap the superblock
3330 and group descriptors.
3332 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
3333 to desp ext2 filesystem structures.
3335 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
3336 supplied by Pete A. Zaitcev so that the C language
3337 versions of these functions are more portable. They will
3338 now work on both little and big endian systems, and the
3339 assumption that 32-bit integers are used is gone.
3341 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
3342 doing byte swapping.
3344 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
3345 byte swapping should take place.
3347 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
3349 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
3350 ext2fs_compare_inode_bitmap_end): Added new file
3351 containing routines to compare bitmaps.

3354 Added new error codes.
3356 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
3358 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
3359 if the magic number is correct, it will be allocated.
3361 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
3363 * block.c (block_iterate_ind, block_iterate_dind,
3364 block_iterate_tind): Don't recompute block_nr each loop;
3365 just increment it! Factor check of BLOCK_FLAG_APPEND out
3366 of the loop. Factor mask of BLOCK_CHANGED into changed
3367 variable out of the loop. (block_iterate_ind, in
3368 particular, gets called a lot, so every little
3369 optimization helps.)
3371 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
3373 * block.c (block_iterate_ind, block_iterate_dind,

3375 block_iterate_ind and company.
3377 * bitops.h (ext2fs_fast_mark_block_bitmap,
3378 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
3379 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
3380 ext2fs_fast_test_inode_bitmap): Add fast version of these
3381 functions, which don't do range checking.
3383 * bitops.h (ext2fs_get_block_bitmap_start,
3384 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
3385 ext2fs_get_inode_bitmap_end): Add new accessor functions
3386 which return the start and end points of the bitmaps.
3388 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
3390 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
3391 instead of llseek. The errno if the offset is too large
3392 and lseek is not supported should be EINVAL, not -EINVAL.
3394 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
3396 * Makefile.in: Added support for ELF shared libraries.
3397 Fixed typos in the compilation rules.
3398 (distclean): Added Makefile.
3400 * llseek.c (llseek): New function, if llseek() does not exist in the
3402 (ext2_llseek): Changed to call llseek().
3404 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3406 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
3408 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3410 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
3412 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
3413 the S_*, which are normally defined in <sys/stat.h>. This
3414 allows us to compile e2fsprogs on a non-Linux system,
3415 which may have a different value for S_IFDIR.
3417 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3419 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
3420 this is a user-mode application!
3422 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
3424 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
3425 __linux__ so that non-linux systems won't see it.
3427 * alloc.c: Include <errno.h> if possible.
3428 * badblocks.c: Ditto.
3429 * bb_inode.c: Ditto.
3432 * expanddir.c: Ditto.
3433 * get_pathname.c: Ditto.
3434 * initialize.c: Ditto.
3441 * rw_bitmaps.c: Ditto.
3444 * Makefile.in: Rewritten to conform to GNU coding standards and
3445 support separate compilation directories.
3447 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
3449 * initialize.c (ext2fs_initialize): Don't allow more than one
3450 bitmaps's worth of inodes in a group.
3452 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
3454 * llseek.c (ext2_llseek): Added error checking to the llseek()
3455 compat code to protect against overflow. This only
3456 applies to 1.0 and early 1.1 kernels, which don't support
3457 the llseek() system call.
3459 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
3461 * unix_io.c (unix_open): Initialize the read_error and write_error
3462 io_channel pointers to be null.
3464 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
3465 found, clear it but don't try to update the filesystem
3466 accounting information, since that's hopeless anyway.
3468 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
3469 bloblock_iterate_tind): Check to see if the indirect blocks are
3470 valid before trying to read them.

3473 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
3475 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
3476 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
3477 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
3478 illegal block or inode number is passed in, return instead
3479 of trying to test, set, or clear the bit.
3481 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
3483 * Makefile: Added a dummy install target in case shared libraries
3486 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
3488 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

3493 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
3494 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
3495 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
3496 ext2fs_free_block_bitmap): Add magic number checking for
3497 the inode and block bitmaps.
3499 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
3500 magic number for a block bitmap instead of an inode bitmap.
3502 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
3503 magic number checking for the inode_scan structure.
3505 * badblocks.c (badblocks_list_free, badblocks_list_add,
3506 badblocks_list_test, badblocks_list_iterate_begin,
3507 badblocks_list_iterate, badblocks_list_iterate_end): Add
3508 magic number checking for the badblocks_list and
3509 badblocks_iterate structures.
3511 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
3512 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
3513 unix_write_blk, unix_flush): Add magic number checking
3514 both for io_channel structure and unix_private_data
3517 * openfs.c (ext2fs_open): Add check for io_manager structure's
3520 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
3521 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
3522 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
3523 * read_bb.c (ext2fs_read_bb_inode):
3524 * read_bb_file.c (ext2fs_read_bb_FILE):
3525 * newdir.c (ext2fs_new_dir_block):
3526 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
3527 * link.c (ext2fs_link, ext2fs_unlink):
3528 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

3535 ext2fs_allocate_block_bitmap):
3536 * bb_inode.c (ext2fs_update_bb_inode):
3537 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
3538 * check_desc.c (ext2fs_check_desc):
3539 * closefs.c (ext2fs_close, ext2fs_flush):
3540 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
3545 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
3546 openfs.c into its own file.
3548 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
3549 structure magic numbers.
3551 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
3552 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
3553 someone uses the -b option to specify the use of the backup
3554 superblock --- this usually means that the main superblock is
3558 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
3559 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
3560 revision level to the superblock.
3562 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
3569 * initialize.c: Completely revamped the inode and block bitmap
3570 structures, so that they can be better chance of being extensible
3571 in a shared library. They are now their own type, instead of
3572 being a char *. Also, the function signatures of
3573 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
3574 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
3575 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
3576 changed to eliminate the ext2_filsys argument, since it is no
3579 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
3581 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
3582 system call if available.
3584 * llseek.c: new file. This is the stub calling the llseek system
3585 call which allows supports for 2GB+ file systems.
3587 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
3588 the creator operating system.
3590 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
3592 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
3593 the group descriptor statistics in addition to everything else.
3594 This relieves mke2fs of the responsibility of doing it.
3596 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
3597 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
3598 not the generic C function equivalents should be included or not.
3600 * openfs.c (ext2fs_open): If a superblock is specified, then use
3601 the backup group descriptors that go along with this superblock,
3602 instead of using the primary group descriptors. This allows
3603 e2fsck to recover filesystems where the primary group descriptors
