1 2006-03-25 Theodore Ts'o <tytso@mit.edu>
3 * Makefile.in: Check the bitfield operations much more carefully,
4 and arrange to have tst_bitops run from "make check"
6 * tst_bitops.c: Enahce tst_bitops program so that it is much more
7 thorough in testing bit optations.
9 * bitops.h: Add new functions ext2fs_fast_set_bit() and
10 ext2fs_fast_clear_bit() and make the x86 functions 32-bit
11 clear. Change the fast inode and block mark/unmark
12 functions to use ext2fs_fast_set/get_bit()
14 2006-03-18 Theodore Ts'o <tytso@mit.edu>
16 * ext2fs.h (EXT2_FLAG_EXCLUSIVE): Define new flag which requests
17 that the io_channel be opened in exclusive mode.
19 * openfs.c (ext2fs_open2), initialize.c (ext2fs_initialize): If
20 EXT2_FLAG_EXCLUSIVE is passed to ext2fs_open or
21 ext2fs_initialize, then pass IO_FLAG_EXCLUSIVE to the
22 io_channel open routine.
24 * ext2_io.h (IO_FLAG_EXCLUSIVE), unix_io.c (unix_open): Add new
25 io_channel open flag, IO_FLAG_EXCLUSIVE, which requests
26 that the device be opened in exclusive (O_EXCL) mode.
28 * ext2fs.h: Fix documentation so that BLOCK_FLAG_TRAVERSE is
29 BLOCK_FLAG_DEPTH_TRAVERSE. (Addresses Debian Bug #351268)
31 2006-03-17 Theodore Ts'o <tytso@mit.edu>
33 * initialize.c (calc_reserved_gdt_blocks): Fix a signed vs
34 unsigned problem which caused mke2fs -O resize_inode to
35 bomb out on large filesystems. (Addresses Debian Bug
38 * ext2_fs.h (EXT2_IOC_GETVERSION_NEW, EXT2_IOC_SETVERSION_NEW,
39 EXT2_IOC_GROUP_EXTEND, EXT2_IOC_GROUP_ADD): Add ioctl
42 2005-12-10 Theodore Ts'o <tytso@mit.edu>
44 * Makefile.in: Add a dependency to make sure that the
45 subdirectories are created before creating all of the
48 2005-12-10 Theodore Ts'o <tytso@mit.edu>
50 * res_gdt.c (ext2fs_create_resize_inode): Fix type-punning warning.
52 * read_bb_file.c (ext2fs_read_bb_FILE): Use a data structure
53 instead of stuffing a function pointer dirctly into a void
54 pointer, since that isn't portable.
56 * mkjournal.c (ext2fs_add_journal_inode): Fix possiblely
57 uninitialized use of variable warning.
59 * initialize.c (calc_reserved_gdt_blocks): Fix signed vs. unsigned
62 * ext2fs.h: Make the type of the 'now' field to be time_t to avoid
65 * bitops.h (ext2fs_find_first_bit_set): Fix signed vs unsigned
68 * tst_badblocks.c (file_test_invalid): Add test which confirms
69 proper detection of invalid block numbers in
70 ext2fs_read_bb_FILE().
72 2005-11-20 Theodore Ts'o <tytso@mit.edu>
74 * bitops.h: We no longer have the sparc assembly code in the
75 header file any more, so we shouldn't set
76 _EXT2_HAVE_AS_BITOPS_. This would break compiles on the
77 sparc architectures when using gcc.
79 2005-11-13 Theodore Ts'o <tytso@mit.edu>
81 * ext2fs.h: Add #include <string.h> since the inline functions use
82 memcpy(). (Addresses Sourceforge Bug #1251062)
84 2005-11-09 Theodore Ts'o <tytso@mit.edu>
86 * Fix a bug when writing an external journal device on an big
87 endian machine (such as a S/390), where when the number of
88 block groups is zero, we never end up writing out the
89 primary superblock at all.
91 2005-09-24 Theodore Ts'o <tytso@mit.edu>
93 * ext2fs.h, bb_inode.c, closefs.c, initialize.c, mkdir.c,
94 mkjournal.c, res_gdt.c: If fs->now is non-zero, use that
95 as the time instead of the system time when setting
96 various filesystem fields (last modified time, last write
99 2005-08-28 Matthias Andree <matthias.andree@gmx.de>
101 * Fix compiler warnings about missing memcpy prototypes.
103 2005-07-25 Theodore Ts'o <tytso@mit.edu>
105 * test_io.c (safe_getenv): Pass in zero to the unusued arguments
106 of prctl(PR_GET_DUMPABLE) to avoid false positives from
109 2005-07-19 Theodore Ts'o <tytso@mit.edu>
111 * mkjournal.c (ext2fs_add_journal_inode): Check for the case where
112 the filesystem is apparently not mounted, but the device
113 is still busy. This can happen when the luser doesn't
114 bother to mount /proc and has a bogus /etc/mtab, but still
115 wants to mount the filesystem before using tune2fs(?!?).
116 Add a safety check to save him from his own stupidity, at
117 least on 2.6 kernels. (Addresses Debian Bug #319002)
119 2005-07-09 Andreas Dilger <adilger@clusterfs.com>
121 * getsize.c (ext2fs_get_device_size): Use fstat/fstat64 to get
122 size of regular files. Fix file descriptor leaks in error
125 2006-06-30 Theodore Ts'o <tytso@mit.edu>
127 * Release of E2fsprogs 1.38
129 2005-06-30 Theodore Ts'o <tytso@mit.edu>
131 * bitops.h, bitops.c (ext2fs_set_bit, ext2fs_clear_bit,
132 ext2fs_test_bit): Change these function prototypes to be
133 unsigned int's. Negative bit numbers were never allowed
134 (and never made any sense), so this should be a safe
135 change. This is needed to allow safe use of block numbers
136 greater than or equal to 2**31.
138 2005-06-27 Stephen Tweedie <sct@redhat.com>
140 * ext2fs.h (ext2fs_resize_mem): Fix C99 strict type aliasing
141 problems. Addresses Red Hat Bugzilla #161183.
143 2005-06-19 Theodore Ts'o <tytso@mit.edu>
145 * getsectsize.c (BLKSSZGET): Clean up test for when to manually
146 define the BLKSSZGET ioctl.
148 2005-05-29 Theodore Ts'o <tytso@mit.edu>
150 * ismounted.c (ext2fs_check_mount_point): Add test to see if the
151 device appears to be busy; this only works on Linux 2.6+
152 systems, but provides some additional bullet-proofing in
155 2005-05-08 Theodore Ts'o <tytso@mit.edu>
157 * test_io.c (safe_getenv): Fix bug so it would fetch the right
158 environment variable.
160 2005-04-09 Theodore Ts'o <tytso@mit.edu>
162 * inode.c (ext2fs_write_new_inode),
163 ind_block.c (ext2fs_read_ind_block): Add missing return
164 value in error return case. (Otherwise we return garbage
165 instead of the error code.)
167 2005-03-31 Theodore Ts'o <tytso@mit.edu>
169 * test_io.c (test_open): If called by a setuid/setgid or an
170 otherwise privileged program, be paranoid and ignore the
171 TEST_IO_* environment variables.
173 2005-03-21 Theodore Ts'o <tytso@mit.edu>
175 * Release of E2fsprogs 1.37
177 2005-03-21 Theodore Ts'o <tytso@mit.edu>
179 * ext2_ext_attr.h (EXT2_XATTR_LEN, EXT2_XATTR_SIZE): Add new
180 convenience cpp macros.
182 2005-03-20 Theodore Ts'o <tytso@mit.edu>
184 * mkdir.c (ext2fs_mkdir): Call ext2fs_write_new_inode() instead of
185 ext2fs_write_inode().
187 * inode.c (ext2fs_write_new_inode): New function which should be
188 used when the caller is writing an inode for the first
189 time. It makes sure that the extra portion of the large
190 inode is initialized properly.
192 2005-03-18 Theodore Ts'o <tytso@mit.edu>
194 * Makefile.in: Fix clean target to remove tst_getsectsize.
196 * getsize.c (ext2fs_get_device_size): Check to see if the number
197 of blocks is greater than 2**32 when we are doing a binary
198 search to determine the device size. Thanks to Stephen
199 Tweedie for the patch.
201 2006-02-05 Theodore Ts'o <tytso@mit.edu>
203 * Release of E2fsprogs 1.36
205 2005-02-05 Theodore Ts'o <tytso@mit.edu>
207 * Makefile.in: Remove ext2fs.pc on a "make distclean"
209 2005-02-04 Theodore Ts'o <tytso@mit.edu>
211 * Makefile.in (clean): Remove tst_getsize when doing a make clean
213 2005-02-03 Theodore Ts'o <tytso@mit.edu>
215 * bitops.c: Make the generic functions more efficient.
217 * bitops.h: Drop SPARC assembly code. It's less efficient than GCC
218 3.4 compiled code and also triggers nasty compiler
219 warnings on sparc64. Thanks to Matthias Andree for his
220 analysis and suggestion.
222 2005-01-27 Theodore Ts'o <tytso@mit.edu>
224 * res_gdt.c (ext2fs_create_resize_inode): Create the resize inode
225 even if s_reserved_gdt_blocks is zero.
227 2005-01-26 Theodore Ts'o <tytso@mit.edu>
229 * ext2fs.pc.in: Add pkg-config files.
231 2005-01-25 Theodore Ts'o <tytso@mit.edu>
233 * ext2fs.h: Add definition of struct ext2_inode_large
235 * ext2_fs.h: Add new function prototypes
237 * ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr): The
238 ext2fs_swap_ext_attr() has been moved to swapfs.c, and
239 given a new argument, has_header.
241 * swapfs.c (ext2fs_swap_ext_attr): Moved from ext_attr.c, and
242 takes an argument which controls whether or not there is
243 an EA header which needs to be byteswaped.
244 (ext2fs_swap_inode_full): New function which byte-swaps
247 * inode.c (ext2fs_get_next_inode_full, ext2fs_read_inode_full,
248 ext2fs_write_inode_full): New functions, originally from
249 Alex Tomas, but which needed to be substantially fixed so
250 that the tests wouldn't cause major stack overwrite bugs
251 in byte-swapping is enabled.
253 2005-01-18 Theodore Ts'o <tytso@mit.edu>
255 * Makefile.in: Fix the kernel compile-time echo commands to be
256 consistent and portable
258 2005-01-07 Theodore Ts'o <tytso@mit.edu>
260 * unlink.c (ext2fs_unlink): If both the name and the inode number
261 are unspecified, then return an error, so that we don't do
262 something surprising such as unconditionally deleting the
263 first directory entry.
264 (unlink_proc): Delete directory entries by coalescing it
265 with the previous entry, to avoid directory fragmentation.
267 2005-01-06 Theodore Ts'o <tytso@mit.edu>
269 * version.c (ext2fs_parse_version_string): Change parsing
270 algorithm so that version strings such as 1.36-rc1 returns
271 a non-surprising result (i.e., 136, and not 1361).
273 2005-01-05 Theodore Ts'o <tytso@mit.edu>
275 * block.c (block_iterate_ind, block_iterate_dind,
276 block_iterate_tind): Move the code which byte swaps and
277 read/writes indirect blocks to ext2fs_{read,write}_ind_block.
278 This saves 400 bytes, and we need them for the
279 resize_inode handling.
281 * ind_block.c (ext2fs_read_ind_block, ext2fs_write_ind_block): New
284 * res_gdt.c (ext2fs_create_resize_inode): Use
285 ext2fs_{read,write}_ind_block so that byte swapping is
286 handled on big-endian systems.
288 * dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handle
289 has its own copy of the orig_super data structure. (This
290 is a better way of fixing a double-free problem in
291 resize2fs which Fedora attempted to fix in
292 e2fsprogs-1.35-double_free.patch. Addresses Red Hat
295 2004-12-23 Theodore Ts'o <tytso@mit.edu>
297 * inode.c (ext2fs_flush_icache): When flushing the icache, clear
298 the last-read block information as well.
300 * ext2fs.h (BMAP_SET), bmap.c (ext2fs_bmap): Add support for new
301 flag, BMAP_SET, which allows the caller to set a
302 particular logical->physical block mapping.
304 * ext2_err.et.in (EXT2_ET_SET_BMAP_NO_IND): New error code
306 * initialize.c (calc_reserved_gdt_blocks): #ifdef out all
307 debugging printf statements.
309 * res_gdt.c (ext2fs_create_resize_inode): Return
310 EXT2_ET_RESIZE_INODE_CORRUPT if the resize inode is not
311 what we expect. #ifdef out all debugging printf
314 * ext2_err.et.in (EXT2_ET_RESIZE_INODE_CORRUPT): Add new error code.
316 2004-12-22 Theodore Ts'o <tytso@mit.edu>
318 * swapfs.c (ext2fs_swap_super): Byteswap the reserved_gdt_blocks
321 2004-12-15 Theodore Ts'o <tytso@mit.edu>
323 * sparse.c (ext2fs_list_backups, ext2fs_bg_has_super),
324 res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
325 ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
326 ext2fs_bg_has_super() back to closefs.c. There's no
327 reason for the new file, since list_backups() isn't being
328 used by any other functions, and can be made static, and
329 all users of the ext2fs filesystem will have to call
330 ext2fs_close() anyway.
332 2004-12-15 Theodore Ts'o <tytso@mit.edu>
334 * Applied resize inode patch from Andreas Dilger
336 * res_gdt.c (ext2fs_create_resize_inode): New function that
337 creates the resize inode.
339 * initialize.c (ext2fs_initialize): Reserve space for the resize
342 * ext2fs.h (EXT2_LIB_FEATURE_COMPAT_SUPP): Add
343 EXT2_FEATURE_COMPAT_RESIZE_INODE to the list of supported
345 Add function prototypes for res_gdt.c and sparse.c.
347 * closefs.c (ext2fs_super_and_bgd_loc): Take the reserved blocks
348 into account when calculating the number of overhead
351 * closefs.c (ext2fs_bg_has_super, test_root), sparse.c: Move these
352 functions to the new file sparse.c
354 * alloc_sb.c (ext2fs_reserve_super_and_bgd): Reserve the blocks
355 saved in the resize inode as being in use.
357 * ext2_err.et.in (EXT2_ET_RES_GDT_BLOCKS): Add new error code.
359 * Makefile.in (srcdir): Add res_gdt.c and sparse.c to the ext2fs

364 * Makefile.in: Use Linux-kernel-style makefile output for "make
367 * Makefile.in (installdirs): Use $(MKINSTALLDIRS) macro
370 2004-11-30 Theodore Ts'o <tytso@mit.edu>
372 * unix_io.c (unix_set_option): Add support for the offset option.
374 * test_io.c (test_set_option): Add support for the set_option method.
376 * ext2_io.h: Add new io_channel method, set_option(), and change
377 io_channel_write_byte() from a macro to a library function.
379 * ext2fs.h, openfs.c(ext2fs_open2): New version of ext2fs_open
380 which adds a new parameter, io_options.
381 (ext2fs_open): If there is a question mark in the
382 filename, and no io_options are specified, assumed that
383 the text following the question mark are io_options.
385 * io_manager.c, Makefile.in: New source file which contains
386 high-level functions for the io_channel layer.
388 * freefs.c (ext2fs_free): Make sure we don't free the io_channel
391 * Makefile.in: Use Linux-kernel-style makefile output to make it
392 easier to see errors/warnings.
394 2004-11-29 Theodore Ts'o <tytso@mit.edu>
396 * ext2_fs.h (EXT2_EXTENTS_FL, EXT3_FEATURE_INCOMPAT_EXTENTS,
397 EXT2_MAX_BLOCK_LOG_SIZE): Add definition for extent
398 feature and inode flag. Change maximum allowable block
401 2004-10-08 Theodore Ts'o <tytso@mit.edu>
403 * getsize.c (ext2fs_get_device_size): Add support for Windows
404 9x/NT under Cygwin. Thanks to Sam Robb
405 (samrobb@users.sourceforge.net) for pointing this and the
406 suggested code patch.
408 2004-09-17 Theodore Ts'o <tytso@mit.edu>
410 * getsize.c: Clean up header #include's.
412 * llseek.c (ext2fs_llseek): On non-linux systems, use lseek64() if
413 it is present. (Addresses Debian bug #269044)
415 2004-07-28 Theodore Ts'o <tytso@mit.edu>
417 * rw_bitmaps.c (read_bitmaps), block.c (block_iterate_ind,
418 block_iterate_dind, block_iterate_tind), inode.c
419 (ext2fs_read_inode): If EXT2_FLAG_IMAGE_FILE is set, so
420 read the metadata from fs->image_io instead of fs->io.
422 * initialize.c (ext2fs_initialize), openfs.c (ext2fs_open):
423 Initialize fs->image_io to be the same as fs->io.
425 * ext2_err.et.in (EXT2_ET_NOT_IMAGE_FILE): Add new error code.
427 * openfs.c (ext2fs_get_data_io, ext2fs_set_data_io,
428 ext2fs_rewrite_to_io): New functions that allow
429 applications to manipulate fs->image_io and fs->io safely.
431 * freefs.c (ext2fs_free): If fs->image_io is different fs->io,
432 then call io_channel_close on fs->image_io.
434 * ext2fs.h: Add image_io element to the ext2_filsys data
435 structure. Add ext2fs_get_data_io() ext2fs_set_data_io(),
436 and ext2fs_rewrite_to_io() prototypes.
438 2004-05-26 Theodore Ts'o <tytso@mit.edu>
440 * closefs.c (ext2fs_flush): Make sure the master superblock is
441 written last, and only after other I/O has been flushed to
442 disk. Thanks to Junfeng Yang from the Stanford
443 Metacompilation group for pointing a potential ordering
444 constraint problem if we don't write things out in the
447 * test_io.c: Implement the ability to abort after n reads or
448 writes to a particular block. The block is specified by
449 TEST_IO_BLOCK environment variable, and the read/write
450 count by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT
451 environment variables. The block data is now only dumped
452 if the 0x10 bit is set in TEST_IO_FLAGS.
454 2004-04-03 Theodore Ts'o <tytso@mit.edu>
456 * ext2_types.h.in: Remove check for _UUID_TYPES since uuid_types.h
459 2004-03-08 Theodore Ts'o <tytso@mit.edu>
461 * getsize.c (ext2fs_get_device_size): Only use the BLKGETSIZE64
462 ioctl on Linux 2.6 since it is unreliable in Linux 2.4.
463 (Addresses Debian Bug #236528). Fix typo in the ioctl
466 2004-03-02 Theodore Ts'o <tytso@mit.edu>
468 * getsize.c (ext2fs_get_device_size): Update getsize functions to
469 use Apple Darwin and Linux 64-bit ioctl's
471 2004-02-29 Brian Bergstrand <brian@bergstrand.org>
473 * Makefile.in: Use $(BSDLIB_PIC_FLAG) to determine whether to use
476 2004-02-28 Theodore Ts'o <tytso@mit.edu>
478 * Release of E2fsprogs 1.35
480 2004-02-21 Theodore Ts'o <tytso@mit.edu>
482 * ext2fs.h (ext2fs_resize_mem): Fix C++ problem. (Addresses Red
483 Hat Bugzilla #112448; thanks Thomas Woerner from Red Hat.)
485 2004-02-14 Theodore Ts'o <tytso@mit.edu>
487 * namei.c (follow_link): Correctly deal with symlinks that have
488 extended attribute information. (Addresses Debian Bug
491 2004-01-30 Theodore Ts'o <tytso@mit.edu>
493 * ext2_fs.h: Reserve an extra 4 bytes for the journal backup,
494 which we're using due to a typo in the e2fsck code. (Oops)
496 * swapfs.c (ext2fs_swap_inode): Fix byte swap bug which causes SE
497 Linux created symlinks with mandatory attributes to fail
498 to be properly handled on big endian systems. (Addresses
500 (ext2fs_swap_super): Byte swap some new fields in the
501 superblock, including the journal backup fields.

508 lookup.c, openfs.c, read_bb.c, read_bb_file.c,
509 rw_bitmaps.c, unix_io.c, unlink.c, write_bb_file.c: Fix
510 gcc -Wall complaints. Mainly marking variables as being
511 unsued, and catching signed vs. unsigned comparisons.
513 2003-09-03 Theodore Ts'o <tytso@mit.edu>
515 * closefs.c (ext2fs_super_and_bgd_loc): New function which
516 centralizes the calculation of the superblock and block
518 (ext2fs_flush): Use ext2fs_super_and_bgd_lock to figure
519 out where to write the superblock and block group
522 * alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
523 reserves space in the block bitmap using
524 ext2fs_super_and_bgd_loc.
526 * initialize.c (ext2fs_initialize): Use
527 ext2fs_reserve_super_and_bgd to initialize the block bitmap.
529 2003-08-20 Theodore Ts'o <tytso@mit.edu>
531 * inode_io.c (ext2fs_inode_io_intern2), ext2fs.h: Add new function
532 allows the caller to pass in the inode data structure.
534 * fileio.c (ext2fs_file_open2), ext2fs.h: Add new function which
535 allows the caller to pass in the inode to be used in the

551 mkjournal.c, namei.c, newdir.c, openfs.c, rs_bitmap.c,
552 rw_bitmaps.c, test_io.c, unix_io.c: ext2fs_getmem(),
553 ext2fs_free_mem(), and ext2fs_resize_mem() all now take a
554 'void *' instead of a 'void **' in order to avoid pointer
555 aliasing problems with GCC 3.x.
557 2003-07-25 Theodore Ts'o <tytso@mit.edu>
559 * Release of E2fsprogs 1.34
561 2003-07-06 Theodore Ts'o <tytso@mit.edu>
563 * kernel-jbd.h, flushb.c: Fix gcc -Wall nitpicks (indented cpp
566 * ext2_types.h.in, initialize.c: Fix gcc -Wall nitpicks
569 * ismounted.c: Fix gcc -Wall nitpicks (Don't use exit as a goto label)
571 * llseek.c: Fix gcc -Wall nitpicks (don't use #elsif)
573 * lookup.c, read_bb.c: Fix gcc -Wall nitpicks (indent
574 non-traditional #pragma)
576 * test_io.c: Fix gcc -Wall nitpicks (const/unsigned type issues)
578 2003-06-24 <tytso@snap.thunk.org>
580 * badblocks.c, ext2fs.h (ext2fs_u32_list_find,
581 ext2fs_u32_list_test, ext2fs_u32_list_del,
582 ext2fs_badblocks_list_del): Add functions to delete a
583 block from the badblocks list.
584 * tst_badblocks.c: Add test cases for ext2fs_badblocks_list_del().
586 2003-05-21 Theodore Ts'o <tytso@mit.edu>
588 * getsectsize.c (ext2fs_get_device_sectsize): New function which
589 returns the hardware sector size (if it is available).
591 2003-05-13 Theodore Ts'o <tytso@mit.edu>
593 * unix_io.c: Add #ifdef NO_IO_CACHE which disables all userspace
594 caching by the unix_io layer. Not enabled, only for
597 2003-05-05 Theodore Ts'o <tytso@mit.edu>
599 * test_io.c: Pay attention to the environment variables
600 TEST_IO_LOGFILE, TEST_IO_FLAGS, and TEST_IO_BLOCK to
601 determine whether or not we should log io activity, and to
604 2003-05-03 Theodore Ts'o <tytso@mit.edu>
606 * tst_badblocks.c (file_test): Use tmpfile() instead of mktemp().
608 2003-04-29 Theodore Ts'o <tytso@mit.edu>
610 * getsize.c (ext2fs_get_device_size): Allow windows code to get
611 the resize for filesystems that are in regular files.
613 2003-04-21 Theodore Ts'o <tytso@mit.edu>
615 * Release of E2fsprogs 1.33
617 2003-04-21 Theodore Ts'o <tytso@mit.edu>
619 * Makefile.in: Use DYLD_LIBRAY_PATH so that "make check" works on
620 Darwin systems when building with shared libraries.
622 2003-04-18 Theodore Ts'o <tytso@mit.edu>
624 * unix_io.c: Use __CYGWIN__ instead of CYGWIN.
626 2003-04-17 Theodore Ts'o <tytso@mit.edu>
628 * getsize.c: Add Cygwin/Windows version of ext2fs_get_device_size()
630 2003-04-12 Theodore Ts'o <tytso@mit.edu>
632 * unix_io.c (raw_read_blk): Add Cygwin support (the Windows block
633 device only accepts sector aligned read requests.
635 * ismounted.c (check_mntent_file): Deal with OS's that don't
638 * imager.c: If the OS doesn't define ssize_t, typedef it to int.
640 2003-04-11 Theodore Ts'o <tytso@mit.edu>
642 * ext2_fs.h (EXT2_FEATURE_RO_COMPAT_BTREE_DIR): Comment out unused
645 2003-03-30 Theodore Ts'o <tytso@mit.edu>
647 * Makefile.in: Use the compile_et --build-tree option.
649 2003-03-14 Theodore Ts'o <tytso@mit.edu>
651 * getsize.c: Add support for Apple Darwin's ioctl to get the hard
654 * badblocks.c (ext2fs_u32_list_count), ext2fs.h: Add new function
655 which returns the number of entries in the list.
657 2003-03-10 Theodore Ts'o <tytso@mit.edu>
659 * fileio.c (ext2fs_file_lseek): Fix bug added when adding 64-bit
660 support; avoid null dereference when ret_pos is NULL.
662 2003-03-06 Theodore Tso <tytso@mit.edu>
664 * ext2_types.h.in: Don't redefine types if other e2fsprogs
665 *_types.h files have been included already.
667 * kernel-jbd.h: Use C99 variadic cpp macros if not using GCC.
668 (Older GCC's don't support the C99 variadic macros.)
670 * flushb.c (ext2fs_sync_device),
671 ismounted.c (ext2fs_check_mount_point): Avoid GCC extension:
672 #warning not supported by Solaris suncc
674 * ext2_ext_attr.h: Avoid GCC extension: 0 length arrays in
675 structure definition. Not needed for now in
678 2003-01-25 Theodore Ts'o <tytso@mit.edu>
680 * dirhash.c: Fix gcc -Wall nits.
682 2003-01-22 Theodore Ts'o <tytso@mit.edu>
684 * unix_io.c (unix_write_blk): Fix up GCC -Wall nits.
686 2003-01-21 Theodore Ts'o <tytso@mit.edu>
688 * fileio.c (ext2fs_file_read, ext2_file_lseek,
689 ext2_file_get_size): Add 64-bit support.
691 * ext2fs.h (EXT2_I_SIZE): Add macro which caluates a 64bit size
692 from i_size and i_size_high.
694 2003-01-19 Theodore Ts'o <tytso@mit.edu>
696 * initialize.c (ext2fs_initialize): If the user specifies a really
697 large number of inodes, then reduce the number of blocks
698 per group until we find a workable set of filesystem
701 * ext2_err.et.in (EXT2_ET_TOO_MANY_INODES): Add new error code.
703 2002-11-09 Theodore Ts'o <tytso@mit.edu>
705 * Release of E2fsprogs 1.32
707 2002-11-09 Theodore Ts'o <tytso@mit.edu>
709 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
710 unix_write_blk): Optimize routines so that we don't end up
711 searching the cache twice when a block isn't in the
712 cache. If reads are larger than READ_DIRECT_SIZE, don't
713 let them go through the cache.
715 * unix_io.c (find_cached_block): Fixed bug which caused some clean
716 blocks to be erroneously marked as dirty, so they would
717 get written back to the disk before they are evicted from
718 the cache. Harmless, but it slows down e2fsck
721 2002-11-08 Theodore Ts'o <tytso@mit.edu>
723 * Release of E2fsprogs 1.31
725 2002-11-08 <tytso@snap.thunk.org>
727 * Makefile.in (check): Skip trying to compile test_byteswap
728 if --disable-byteswaap had been given to configure.
730 2002-11-07 <tytso@snap.thunk.org>
732 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
733 support when the MASTER_SB_ONLY flag is set. Some of
734 the descriptor blocks that should have been written out
735 were getting skipped.
737 2002-10-31 Theodore Ts'o <tytso@mit.edu>
739 * Release of E2fsprogs 1.30
741 2002-10-31 Theodore Ts'o <tytso@mit.edu>
743 * ext2_fs.h: Add support for a new inode flag, which is to be used
744 for indicating the top of directory hierarchies for the
745 Orlov block allocator.
747 * ismounted.c (check_mntent, check_mntent_file): Add better
748 support for loopback-mounted filesystems. Check /etc/mtab
749 if /proc/mounts doesn't turn up any mount flags, since
750 /etc/mtab has the loopback image filename, instead of
751 /dev/loop0. Also, check based on st_dev and st_ino, so
752 that if a relative pathname or a pathnames using symbolic
753 links are used, we can detect the the filesystem correctly
754 in those cases. (Addresses Sourceforge bug #619119)
756 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
757 don't try the FDFLUSH ioctl that was required for floppies
758 with older kernels. This avoids needless whining from the
759 MD device driver. (Addresses Sourceforge bug #545832).
761 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
762 wrong group_block to ext2fs_descriptor_block_loc if we're
763 using the backup superblock/block group descriptors.
764 (ext2fs_descriptor_block_loc): If we're using the backup
765 superblock descriptors, use the backup descriptor block in
766 the next block group.
768 2002-10-30 Theodore Ts'o <tytso@mit.edu>
770 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
771 table so that it buts up against the bitmap blocks, to
772 avoid block fragmentation.
774 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
775 bug; only allocate group descriptor blocks up to
778 2002-10-25 Theodore Ts'o <tytso@mit.edu>
780 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
781 know when a filesystem was created. (Sometimes this can
784 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
786 2002-10-20 Theodore Ts'o <tytso@valinux.com>
788 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
789 the journal data mode.
791 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
792 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
793 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
794 the meta_blockgroup filesystem format.
796 2002-10-15 <tytso@snap.thunk.org>
798 * ext2_fs.h: Add new field in superblock for default mount options.
800 2002-10-13 Theodore Ts'o <tytso@mit.edu>
802 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
805 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
807 * rw_bitmaps.c (ext2fs_write_block_bitmap,
808 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
809 because the bitmap is getting written to disk. Make
810 ext2fs_swap_bitmap be a static function, since it's not
811 intended to be exported.
813 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
815 2001-09-24 Theodore Tso <tytso@mit.edu>
817 * Release of E2fsprogs 1.29
819 2001-08-31 Theodore Tso <tytso@thunk.org>
821 * Release of E2fsprogs 1.28
823 2002-08-31 Theodore Ts'o <tytso@valinux.com>
825 * dblist.c (ext2fs_dblist_sort): New function which allows the
826 caller to pass in a special sort comparison function.
828 2002-08-20 Theodore Ts'o <tytso@mit.edu>
830 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
831 failed to accurately characterize non-standard slow
832 symlinks. (Which don't appear in practice on real-life
833 systems, fortunately.)
835 2002-08-17 Theodore Ts'o <tytso@mit.edu>
837 * Makefile.in: Remove inode_io.o from the standard object files,
838 and only build it if debugfs is enabled (it requires
839 fileio.o, which is only built if --disable-debugfs isn't
840 specified to configure).
842 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
843 incompatible way so that it is no longer
844 endian-dependent. Add the TEA hash. Allow the seed
845 parameter to be optional.
847 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
848 These features are all now in the HALF_MD4 hash. Add
849 definition for EXT2_HASH_TEA.
851 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
852 a pointer instead of an array.
854 2002-08-16 Theodore Ts'o <tytso@mit.edu>
856 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
858 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
859 the number of data blocks used by an inode exclusive of
862 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
863 adjusts the reference count in an extended attribute block.
865 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
866 correctly deal with extended attribute blocks in symbolic
869 2002-08-13 <tytso@snap.thunk.org>
871 * Makefile.in: Move dupfs.o and test_io.o from the
872 needed-by-debugfs object list to the needed-by-resizer
873 object list. Fixes compile problem if the system is built
874 with only --disable-debugfs.
876 2002-07-29 Theodore Ts'o <tytso@mit.edu>
878 * link.c (ext2fs_link): When adding a new link to a directory,
881 2002-07-23 Theodore Ts'o <tytso@mit.edu>
883 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
884 calculations for names > 32 characters to be completely
885 bogus. Changed MD4 calculation to match what is currently
886 being used in the CVS gkernel tree.
888 2002-07-19 Theodore Ts'o <tytso@mit.edu>
890 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
891 superblock definition.
893 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
894 create a set of u32_list functions.
896 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
897 since that's required by the directory indexing code.
899 2002-07-14 Theodore Ts'o <tytso@mit.edu>
901 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
902 using a C++ reserved word.
904 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
905 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
906 old version of glibc (built against 2.2 headers) will
907 interact badly with the workaround to actually cause more
908 problems. I hate it when the glibc folks think they're
909 being smarter than the kernel....
911 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
913 * ext2_fs.h: Add superblock field for reserved group descriptors.
915 2002-06-28 Theodore Ts'o <tytso@mit.edu>
917 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
918 ext2fs_cpu_to_{l,b}e{32,16}
920 2002-06-27 Theodore Ts'o <tytso@mit.edu>
922 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
923 Add appropriate fallbacks in this case.
925 2002-06-26 Theodore Ts'o <tytso@mit.edu>
927 * dirhash.c (ext2fs_dirhash): Change function signature to support
928 a hash seed, and to return the minor hash (for 64-bit hash
929 support). Add support for the half MD4, half MD4 with
930 seed, and half MD4 with seed and 64 bits.
932 2002-06-15 Theodore Ts'o <tytso@mit.edu>
934 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
936 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
938 * ext2_fs.h: Add macros for maximum block/inode counts:
939 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
940 and EXT2_MAX_INODES_PER_GROUP.
942 * openfs.c (ext2fs_open): Check that the number of blocks in a group
943 is less than 2^16, otherwise we need an INCOMPAT flag (not
944 in existence yet, if ever) to open such a filesystem.
946 * initialize.c (ext2fs_initialize): Limit the number of blocks and
947 inodes in a group to less than 2^16.
949 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
951 * ext2_fs.h: Further minor cleanups of the header. Consolidate
952 some checks for __KERNEL__ into one place.
954 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
956 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
957 the EXT2_SB() macro instead. Remove kernel function
958 prototypes also. This matches the 2.5 kernel, and
959 is also cleaner for other reasons. Whitespace cleanup.
961 2002-05-21 Theodore Ts'o <tytso@mit.edu>
963 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
965 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
967 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
969 * initialize.c (ext2fs_initialize): Remove assumption that
970 blocksizes are always <= 4k.
972 2002-05-11 Theodore Ts'o <tytso@mit.edu>
974 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
975 silently if inode pointer is NULL (and ext2fs_bmap is
976 expected to read the inode itself).
978 2002-04-27 Theodore Ts'o <tytso@mit.edu>
980 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
981 file we are checking is a block device file before looking
982 at st_rdev, since it's not valid for normal files.
983 (is_swap_device): Move so that it is outside the
984 HAVE_MNTENT_H, so that it is always built.
986 2002-03-11 Theodore Tso <tytso@mit.edu>
988 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
989 functions which take an extra flags argument. The flag
990 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
991 field is byte swampped on big-endian machines, since in
992 the V2 structure, name_len is a char field which is
993 doesn't need to be byte swapped --- except if an
994 old-style kernel had byte-swapped the name_len field
995 as part of the V1 structure.
997 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
999 * dirhash.c (ext2fs_dirhash): New function which calculates the
1000 hash for a filename in an indexed directory.
1002 2002-03-08 Theodore Tso <tytso@mit.edu>
1004 * Release of E2fsprogs 1.27
1006 2002-03-07 Theodore Tso <tytso@mit.edu>
1008 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
1010 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
1011 tst_byteswap.c: Fix gcc -Wall complaints
1013 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
1014 (From Philipp Thomas <pthomas@suse.de>)
1016 2002-02-25 Theodore Tso <tytso@mit.edu>
1018 * ext2_fs.h: Add structure definitions for the directory indexing
1021 2002-02-23 Theodore Tso <tytso@mit.edu>
1023 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
1024 it doesn't break things on mis32, sparc32, and alpha
1027 2002-02-21 Theodore Tso <tytso@mit.edu>
1029 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
1030 we were missing an fclose().
1032 2002-02-20 Theodore Tso <tytso@mit.edu>
1034 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
1035 abstraction interface which exports an ext2 inode.
1037 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
1038 as a public interface. Change void * to const void * in
1039 ext2fs_file_write's interface.
1041 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
1042 conditional; save a few bytes.
1044 2002-02-12 Theodore Tso <tytso@mit.edu>
1046 * Makefile.in (tst_badblocks): Add some extra .o files when
1047 linking the debugging program tst_badblocks which are
1048 needed if we aren't compiling with inline functions enable.
1050 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
1051 define away __inline__ since it may not be supported.
1053 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
1054 stripped down jbd_debug that doesn't use variadic
1055 arguments. This will cause warnings under AIX, but things
1058 2002-02-03 Theodore Tso <tytso@thunk.org>
1060 * Release of E2fsprogs 1.26
1062 2002-02-03 Theodore Tso <tytso@mit.edu>
1064 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
1065 so that the number of directories in use is adjusted
1068 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
1069 which optionally will modify the number of directories
1072 2002-01-03 Theodore Tso <tytso@mit.edu>
1074 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
1075 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
1076 which will return deleted directory entries.
1077 ext2fs_dir_iterate2 takes a new callback function which
1078 is identical with the one used by
1079 ext2fs_dblist_dir_iterate(). If the directory entry is
1080 deleted, the callback function will be called with the
1081 entry paraemter set to DIRENT_DELETED_FILE.
1083 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
1084 ext2fs_block_alloc_stats): New functions which update
1085 block/inode allocation statistics in the bitmaps, block
1086 group descriptors, and superblock.
1088 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
1089 expanddir.c (expand_dir_proc), bb_inode.c
1090 (clear_bad_block_proc, set_bad_block_proc,
1091 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
1092 Update to use new block/inode allocation statistics.
1094 2001-12-24 Theodore Tso <tytso@mit.edu>
1096 * ismounted.c (is_swap_device): New function used by
1097 ext2fs_check_if_mounted and ext2fs_check_mount_point which
1098 determines whether or not the specified device is a swap
1099 device by using /proc/swaps. More bulletproofing for
1100 idiotic/careless system administrators!
1102 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
1103 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
1104 field to struct_ext2_filsys, umask. This field is
1105 initialize to 022, and affects ext2fs_mkdir in the obvious
1106 way. (In the future umask should also affect new file
1107 creation routines, but the fileio functions don't
1108 currently support this yes.)
1110 * ismounted.c (check_mntent_file): Stat all of the entries in
1111 /etc/mtab and/or /proc/mounts in order to catch dim-witted
1112 system administrators who might have created alias
1115 2001-12-23 Theodore Tso <tytso@mit.edu>
1117 * Makefile.in, jfs_user.h: Move linux/jbd.h to
1118 ext2fs/kernel-jbd.h, to avoid using the system header
1119 file version of hbd.h when using diet glibc (since it
1120 forcibly adds /usr/include to the beginning of the
1121 include search path.)
1123 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
1124 include/linux directory.
1126 2001-12-16 Theodore Tso <tytso@mit.edu>
1128 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
1129 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
1130 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
1132 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
1135 2001-12-03 Theodore Tso <tytso@mit.edu>
1137 * unix_io.c (unix_open): Make sure the ulimit workaround works
1138 regardless of the version of glibc which is used to
1141 2001-11-26 Theodore Tso <tytso@mit.edu>
1143 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
1144 trying to unset the filesize limit if at all possible,
1145 if a block device is getting opened. (The filesize limit
1146 shouldn't be applied against writes to a block device, but
1147 starting in 2.4.10, the kernel is doing this.)
1149 2001-11-05 Theodore Tso <tytso@mit.edu>
1151 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
1152 file on adding a journal to an already-mounted filesystem,
1153 try to clear the ext2 file attributes on an already
1154 existing .journal file so that we don't fail if on a
1155 partially added journal to the filesystem.
1157 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
1158 which signals that a particular inode should not have the
1159 last bits of data (the "tail") be merged with another
1160 file. This is necessary to keep LILO happy.
1162 2001-09-20 Theodore Tso <tytso@thunk.org>
1164 * Release of E2fsprogs 1.25
1166 2001-09-16 Theodore Tso <tytso@mit.edu>
1168 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
1169 which was breaking the build on the Hurd. (Addresses
1170 Debian bug #112414).
1172 2001-09-13 Theodore Ts'o <tytso@mit.edu>
1174 * ismounted.c (check_mntent_file): We now validate the entry in
1175 /etc/mtab to make sure the filesystem is really mounted,
1176 since some broken distributions (read: Slackware) have
1177 buggy boot scripts that don't initialize /etc/mtab before
1178 checking non-root filesystems. (Slackware also doesn't
1179 check the root filesystem separately, and reboot if the
1180 root filesystem had changes applied to it, which is
1181 dangerous and broken.)
1183 2001-09-02 Theodore Tso <tytso@thunk.org>
1185 * Release of E2fsprogs 1.24a
1187 2001-08-30 Theodore Tso <tytso@thunk.org>
1189 * Release of E2fsprogs 1.24
1191 2001-08-30 Theodore Tso <tytso@valinux.com>
1193 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
1194 changes, since the ioctl number has been reused by another
1197 2001-08-15 Theodore Tso <tytso@valinux.com>
1199 * Release of E2fsprogs 1.23
1201 2001-08-05 Theodore Tso <tytso@valinux.com>
1203 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
1204 version of the bitmap test routines to speed up these
1205 routines. (At some point I may want to make these
1206 routines use the find_first_bit functions, but that will
1207 add a lot of complexity since it means that these
1208 functions will have to break the bitmap abstraction
1209 boundary. It's not clear it's worth it.)
1211 * mkjournal.c (mkjournal_proc): Remember the last block allocated
1212 to speed up ext2fs_new_block().
1214 2001-07-29 Theodore Tso <tytso@valinux.com>
1216 * finddev.c (scan_dir): Fix memory leak; we weren't calling
1217 closedir() when exiting the function in all cases.
1219 2001-07-27 Theodore Tso <tytso@valinux.com>
1221 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
1222 block usable in the journal for external journals to be 2
1223 or 3, depending on the blocksize, so that the existing
1224 kernel code does the right thing.
1226 * getsize.c (ext2fs_get_device_size): Add support for the
1227 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
1228 from Ben LaHaise, but it's likely this interface won't
1231 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1232 when writing the journal superblock, too. (Oops! Needed
1233 to make 1k filesystems with external journal to work.)
1235 2001-07-26 Theodore Tso <tytso@valinux.com>
1237 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1238 to find the journal superblock if the blocksize is 1024.
1240 2001-07-21 Theodore Tso <tytso@valinux.com>
1242 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
1244 2001-07-20 Theodore Tso <tytso@valinux.com>
1246 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
1247 attribute block, set the filesystem changed bit.
1249 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1250 Comment out these functions since we're not using them.
1252 2001-07-10 Theodore Tso <tytso@valinux.com>
1254 * closefs.c (write_primary_superblock): After writing changes to
1255 the primary superblock, update the original superblock
1256 copy so we don't have to re-write those changes in the
1258 (ext2fs_flush): Clear the superblock dirty flag after
1259 we've flushed out changes to disk.
1261 2001-07-07 Theodore Tso <tytso@valinux.com>
1263 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
1264 to avoid register conflicts when compiling in PIC mode.
1266 2001-07-04 Theodore Tso <tytso@valinux.com>
1268 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1269 Add new functions (C and in i386 assembler) which quickly
1270 find bits set in a bitmask.
1272 2001-06-23 Theodore Tso <tytso@valinux.com>
1274 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
1275 ext2_ext_attr.h and ext_attr.c for extended attributes
1278 * Release of E2fsprogs 1.22
1280 2001-06-22 Theodore Tso <tytso@valinux.com>
1282 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
1283 descriptor so that adding a journal to a mounted
1284 filesystem doesn't die. (Fixes a bug accidentally
1285 introduced in e2fsprogs 1.21.)
1287 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
1288 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
1289 fchflags without defining UF_NODUMP. (Addresses Debian
1292 * flushb.c: Use platform independent method of defining the
1293 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
1294 since on newer glibc's BLKFLSBUF is defined there.
1296 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
1297 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
1298 to support byte swapping even if we don't support the
1299 conversion functions. (Fixes Debian bug #101686).
1301 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
1302 since the byte-swapping code all assumes the
1303 ext2_dir_entry structure. (It's a question of whether or
1304 not name_len should be byte-swapped or not, and whether
1305 it's a 16 bit or 8 bit field.)
1307 2001-06-15 Theodore Tso <tytso@valinux.com>
1309 * Release of E2fsprogs 1.21
1311 2001-06-15 Theodore Tso <tytso@valinux.com>
1313 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
1314 file which is generated and is therefore found in the
1315 build directory, not source directory.
1317 * ismounted.c (check_mntent_file): Use a test file in / to check
1318 to see if the root filesystem is mounted read-only. This
1319 protects against the case where /etc might not be on /, as
1320 well as the case where /etc/mtab doesn't exist. (Both are
1321 should-never happen scenarios, but you never know...)
1323 2001-06-14 Theodore Tso <tytso@valinux.com>
1325 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
1326 Remove unneeded #pragma argsused, since the arguments are
1329 2001-06-13 Theodore Tso <tytso@valinux.com>
1331 * ext2_types.h.in: If linux/types.h has been defined, then don't
1332 try to redefine the typedefs.
1334 * Makefile.in (HFILES): Add ext2_types.h to the list of files
1335 which should be installed.
1337 * ismounted.c (check_mntent_file): Work around GNU hurd brain
1338 damage. Addresses Debian bug #100304.
1340 * Makefile.in: Limit some .o files from being included into the
1341 library if --disable-debugfs, --disable-swapfs,
1342 --disable-imager, or --disable-resizer are used.
1344 2001-06-12 Theodore Tso <tytso@valinux.com>
1346 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
1347 function, and use the ext2fs_badblocks_* functions
1350 2001-06-11 Theodore Tso <tytso@valinux.com>
1352 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
1353 ext2fs_mark_generic_bitmap and
1354 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
1355 functions. (This saves space and doesn't significantly
1356 change the speed of e2fsck on a P-III.)
1358 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
1359 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
1360 include the byte-swapping logic if ENABLE_SWAPFS is turned
1361 on or if we're on a big-endian machine.
1363 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
1364 set EXT2_FLAG_SWAP_BYTES, instead of using
1367 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
1368 autoconf to determine whether or not return
1369 EXT2_FLAG_SWAP_BYTES.
1371 2001-06-10 Theodore Tso <tytso@valinux.com>
1373 * Makefile.in: Remove the dependence on the libe2p library.
1375 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
1376 with direct usage of the ioctl/fchflags so that we don't
1377 have to depend on the libe2p library.
1379 2001-06-08 Theodore Tso <tytso@valinux.com>
1381 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
1382 when trying to find a 32-bit wide type.
1384 * icount.c (insert_icount_el): Fix the code used to estimate the
1385 size of the new icount array to be more intelligent, to
1386 avoid reallocating the array too many times. Thanks to
1387 Enrique Perez-Terron for pointing this out.
1389 2001-06-02 Theodore Tso <tytso@valinux.com>
1391 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
1392 for a symlink to determine whether it is a fast symlink.
1394 2001-06-01 Theodore Tso <tytso@valinux.com>
1396 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
1397 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
1399 2001-05-25 Theodore Tso <tytso@valinux.com>
1401 * Release of E2fsprogs 1.20
1403 2001-05-25 Theodore Tso <tytso@valinux.com>
1405 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
1406 some to clean up Andreas's patches. Use strncpy instead
1407 of strcpy to save the root's mountpoint. Clean up #ifdef
1408 structure. Remove uneeded variable in testing/debug driver.
1410 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
1412 * ismounted.c: Add check for root device which doesn't depend on
1413 /etc/fstab or /proc/mounts to be correct. Don't call
1414 endmntent() before we are done with mnt struct.
1416 2001-05-23 Theodore Tso <tytso@valinux.com>
1418 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
1421 2001-05-21 Theodore Tso <tytso@valinux.com>
1423 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
1424 make room for pre-existing usage of
1425 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
1426 the same codepoint as EXT2_BTREE_FL.
1428 2001-05-20 Theodore Tso <tytso@valinux.com>
1430 * ext2fs.h: #include <> instead of "" for ext2fs and et header
1431 files, since they will be installed in /usr/include
1433 2001-05-14 Theodore Tso <tytso@valinux.com>
1435 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
1436 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1437 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
1438 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,
1439 expanddir.c, ext2_fs.h, fileio.c, finddev.c, flushb.c,
1440 freefs.c, get_pathname.c, getsize.c, icount.c, imager.c,
1441 initialize.c, inline.c, inode.c, irel_ma.c, ismounted.c,
1442 link.c, lookup.c, mkdir.c, mkjournal.c, namei.c, native.c,
1443 newdir.c, nt_io.c, openfs.c, read_bb.c, read_bb_file.c,
1444 rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c,
1445 tst_badblocks.c, tst_byteswap.c, tst_getsize.c,
1446 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
1447 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
1448 Adjust all files in this directroy to include this file.
1450 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
1453 2001-05-05 Theodore Tso <tytso@valinux.com>
1455 * fileio.c (ext2fs_file_read): Factored out common code and
1456 cleaned up function. Fixed a bug where if there was an
1457 error reading from the disk, the number of bytes read
1458 wasn't reliably set. (Fixes Debian bug #79163)
1459 (ext2fs_file_write): Factored out common code and made
1460 function more efficient; if writing a full block, don't
1461 bother to do a read-modify-write cycle.
1463 2001-05-04 Theodore Tso <tytso@valinux.com>
1465 * dirblock.c (ext2fs_read_dir_block): Check for an directory
1466 record length which isn't a multiple four, and treat that
1467 as an invalid. Scan the directory and return an error
1468 (EXT2_ET_DIR_CORRUPTED) if the directory records are
1470 (ext2fs_write_dir_block): If while byte-swapping the
1471 directory block, if there's an error, abort and return
1472 EXT2_ET_DIR_CORRUPTED.
1474 2001-05-02 Theodore Tso <tytso@valinux.com>
1476 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
1477 image_header field in the ext2_filsys structure
1479 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
1480 * inode.c (ext2fs_read_inode):
1481 * rw_bitmaps.c (read_bitmaps):
1482 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
1484 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
1485 sure the full bitmap is saved.
1487 2001-05-01 Theodore Tso <tytso@valinux.com>
1489 * e2image.h (struct ext2_image_hdr): Add space for the device name
1490 in the image header.
1492 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
1493 make sure the rec_len is a multiple of 4, to prevent
1494 bus-errors on architectures which care about mis-aligned
1497 2001-04-25 Theodore Tso <tytso@valinux.com>
1499 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
1500 query the device sizes using the BLKGETSIZE ioctl.
1502 2001-04-16 Theodore Tso <tytso@valinux.com>
1504 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
1505 before checking /etc/mtab. The EXT2_MF_READONLY flag is
1506 now set from the /etc/mtab options field for all
1507 filesystems, not just the root filesystem. Add debugging
1508 code to make it easier to test ext2fs_check_if_mounted().
1510 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
1511 check; return an error if there's an attempt to create a
1512 journal less than 1024 filesystem blocks.
1514 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
1515 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
1517 2001-02-20 Theodore Tso <tytso@valinux.com>
1519 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
1522 * tst_byteswap.c: New function to test the byteswap functions.
1523 Add to regression test suite.
1525 2001-02-08 Theodore Tso <tytso@valinux.com>
1527 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
1529 2001-02-07 Theodore Tso <tytso@valinux.com>
1531 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
1532 of s_first for external devices to always be 1, since
1533 jsb->s_first is always relative to the start of the
1534 journal superblock. Use htonl(1) when setting s_nr_users.
1536 2001-01-17 Theodore Ts'o <tytso@valinux.com>
1538 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
1539 device number of the filesystem (instead of the journal)
1540 was being dropped into s_journal_dev.
1542 2001-01-15 Theodore Ts'o <tytso@valinux.com>
1544 * initialize.c (ext2fs_initialize): Add support for initializing
1545 the ext2 superblock for external journal devices. This
1546 basically means we don't bother to allocate any block
1549 * openfs.c (ext2fs_open): Only open external journal devices if
1550 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
1551 ext2fs_open. When opening such devices, don't try to read
1552 the block group descriptors, since they're not there.
1554 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
1556 * mkjournal.c: Export a new function,
1557 ext2fs_create_journal_superblock(), which allocates and
1558 returns a buffer containing a journal superblock. This is
1559 needed by mke2fs to create an external journal. Rewrote
1560 ext2fs_add_journal_device() so that it no longer creates
1561 the external journal, but rather adds a filesystem to an
1562 existing external journal. It handles all of the UUID
1565 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
1566 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
1567 Changed function prototype for ext2fs_add_journal_device().
1569 2001-01-14 Theodore Ts'o <tytso@valinux.com>
1571 * closefs.c (ext2fs_flush): Don't write out anything beyond the
1572 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
1575 2001-01-12 Theodore Ts'o <tytso@valinux.com>
1577 * imager.c: Fix gcc -Wall complaints and a series of bugs where
1578 retval wasn't set correctly. (Thanks to Andreas Dilger
1579 for pointing this out.)
1581 2001-01-11 <tytso@snap.thunk.org>
1583 * flushb.c (ext2fs_sync_device): New function which centralizes
1584 all of the places which might try to use the BLKFLSBUF
1585 or FDFLUSH ioctls (and usually failing to define them
1586 since the system header files don't usually do this for
1587 us, and we're trying to avoid usage of kernel include
1590 2001-01-10 <tytso@snap.thunk.org>
1592 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
1593 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
1594 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
1595 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
1596 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
1597 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
1598 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
1599 ext2_ino_t, to protect applications that attempt to
1600 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
1601 changes ino_t(!?). So we use ext2_ino_t to avoid an
1602 unexpected ABI change.
1604 2001-01-05 <tytso@snap.thunk.org>
1606 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
1607 we may overrun allocated memory in case of a corrupted
1608 filesystem (or an e2fsck test case :-) when byte-swapping
1609 the directory block.
1611 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
1613 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
1614 complaints including a missing return 0 at the end of
1615 ext2fs_add_journal_device.
1617 2001-01-03 <tytso@snap.thunk.org>
1619 * Makefile.in: Link in libe2p when creating libext2fs as a shared
1620 library, since mkjournal.c now references fsetflags().
1622 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
1623 Dilger's changes (with fixups) to allow on-line creation
1626 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
1627 EXT2_FLAG_SUPER_ONLY, which the close routines to only
1628 update the superblock, and not the group descriptors.
1630 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
1632 * ismounted.c: add ext2fs_check_mount_point() function, which will
1633 optionally return the mount point of a device if mounted
1635 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
1637 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
1638 ext2fs_add_journal_inode()
1640 2001-01-01 <tytso@snap.thunk.org>
1642 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
1643 source (but not binary) compatibility of some users of the
1644 ext2 library. They should just simply do a global search
1645 and replace of struct ext2fs_sb with struct
1646 ext2_super_block, and use their own private copy of
1647 ext2_fs.h if they aren't already.
1649 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
1650 Replace use of ext2fs_sb with ext2_super_block.
1652 2000-12-31 <tytso@snap.thunk.org>
1654 * ext2fs.h: Cleaned up header file by removing definitions of
1655 feature flags that might not have been defined in older
1656 ext2 header files. Now that we're using our own
1657 include/linux/ext2fs.h header file, this can never happen.
1659 * jfs_dat.h: Removed old header file which is no longer needed.
1661 2000-12-13 Theodore Ts'o <tytso@valinux.com>
1663 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
1664 by Andreas Dilger to update the filesystem revision to
1667 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
1670 2000-12-09 <tytso@snap.thunk.org>
1672 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
1673 ext2fs_add_journal_device): Add a new argument to the APIs
1674 of these function, which is a flags word. This is used to
1675 allow the creation of a V1 superblock for those folks who
1676 are using ext3 0.3b in production. Note, the user-land
1677 interface for getting at this flag won't be documented, as
1678 the V1 superblock is deprecated.
1680 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
1681 which creates a V2 superblock instead of a V1 superblock.
1683 2000-11-21 <tytso@snap.thunk.org>
1685 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
1686 out by Andreas Dilger.
1688 2000-11-05 <tytso@snap.thunk.org>
1690 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
1691 ext2_fs.h, Makefile.in: New file that has routines that
1692 save ext2fs metadata to a file.
1694 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
1696 * e2image.h: New file which defines the file format for the ext2
1697 image file. (Saved copy of ext2 metadata to a file as a
1698 saving throw against worst-case damage.)
1700 2000-11-01 <tytso@snap.thunk.org>
1702 * inode.c (ext2fs_flush_icache): Add new function
1703 ext2fs_flush_icache() which flushes the internal inode
1704 cache. Applications which modify the inode table blocks
1705 directly must call this function.
1707 2000-10-26 <tytso@snap.thunk.org>
1709 * mkjournal.c: Add #include of netinet/in.h, since Solaris
1710 requires it for ntohl().
1712 * ext2_io.h (io_channel_write_byte): Add new interface to allow
1713 callers to write specific byte ranges. This is an
1714 optional interface, which not all IO channels may
1717 * unix_io.c (unix_write_byte):
1718 * test_io.c (test_write_byte): Add implementation of the
1719 write_byte function.
1721 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
1722 function which writes the primary superblock. If the IO
1723 channel supports writing raw bytes directly, only fields
1724 which were modified are written to the disk. This makes
1725 it safe(r) to use utilities like tune2fs on a mounted
1728 * freefs.c (ext2fs_free): Free the original superblock if it is
1731 * openfs.c (ext2fs_open): Store a copy of the original superblock
1734 * ext2fs.h: Add a field to store the original superblock in the
1735 ext2 context structure.
1737 2000-10-24 <tytso@snap.thunk.org>
1739 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
1740 don't need to use llseek).
1742 2000-10-24 <tytso@valinux.com>
1744 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
1745 creating an ext3 journal on a filesystem.
1747 2000-08-21 <tytso@valinux.com>
1749 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
1751 2000-08-22 <tytso@valinux.com>
1753 * unix_io.c: Make massive changes to support a multiple block
1754 writethrough cacheing.
1756 * ext2_io.h: Added flags field to the io_channel structure.
1758 2000-08-19 <tytso@valinux.com>
1760 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
1761 provides the function ext2fs_find_block_device(). This
1762 function returns the pathname to a block device, given its
1765 2000-07-13 <tytso@valinux.com>
1767 * Release of E2fsprogs 1.19
1769 2000-07-07 Theodore Ts'o <tytso@valinux.com>
1771 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
1772 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
1773 list of filesystem flags supported by the library.
1775 2000-07-04 Theodore Ts'o <tytso@valinux.com>
1777 * ext2fs.h: Update to include latest journalling additions to the
1780 * dll/jump.funcs: Add new jumptable entries for
1781 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1782 ext2fs_badblocks_equal.
1784 * tst_badblocks.c: Update test program to test
1785 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
1787 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
1788 writes out bad blocks list to a file.
1790 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
1791 changes the callback function to take two additional
1792 arguments; a private blind pointer supplied by the caller,
1793 and pointer to a char * containing a pointer to the
1796 * badblocks.c (ext2fs_badblocks_equal): Add new function which
1797 returns true if two badblocks list are equal.
1799 * Makefile.in: Remove explicit link of -lc in the shared library.
1800 (It shouldn't be necessary, and is harmful in some cases).
1802 2000-06-10 Theodore Ts'o <tytso@valinux.com>
1804 * getsize.c (main): Add debugging code under #ifdef DEBUG
1806 2000-05-27 Theodore Ts'o <tytso@valinux.com>
1808 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
1809 earlier, so that if there's an error reading it, we can
1810 more cleanly back out of the operation.
1812 2000-05-25 <tytso@snap.thunk.org>
1814 * getsize.c (ext2fs_get_device_size): Use open64() instead of
1815 open() if it exists. Under linux, manually define the
1816 ioctl for BLKGETSIZE if it isn't already defined and it's
1819 * unix_io.c (unix_open): Use open64() instead of open() if it
1822 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1823 available (and prototypes are defined) use it in
1824 preference to llseek.
1826 * Makefile: Add hack dependency rule so that parallel makes work
1829 2000-05-18 Theodore Ts'o <tytso@valinux.com>
1831 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
1833 2000-04-03 Theodore Ts'o <tytso@valinux.com>
1835 * block.c: Readibility tweak in conditionals involving
1838 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
1839 how to define __s64 and __u64. Turn off "compression is
1840 experimental" warning if the cpp macro
1841 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
1843 2000-02-11 <tytso@snap.thunk.org>
1845 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
1846 Conditionally include Compression as a supported type if
1847 ENABLE_COMPRESSION (via --enable-compression) is turned on.
1849 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
1851 2000-02-08 <tytso@snap.thunk.org>
1853 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
1854 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1855 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
1856 Change to return the previous state of the bit that is
1857 being marked or unmarked. For speed optimization.
1859 2000-02-02 Theodore Ts'o <tytso@valinux.com>
1861 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
1863 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
1864 needed any more; we know it will always be i_generation.
1865 Add support for swapping the high bits of the uid and gid.
1867 1999-11-19 <tytso@valinux.com>
1869 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1870 counts if the link was successful. Patch suggested by
1873 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
1874 the source directory.
1876 1999-11-10 <tytso@valinux.com>
1878 * Release of E2fsprogs 1.18
1880 1999-11-08 <tytso@valinux.com>
1882 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1883 since ext2fs_badblocks_list_free was moved to freefs.c.
1885 * tst_badblocks.c: Use the newer badblocks API names. Add
1886 duplicate blocks to the test inputs to test dealing with
1887 adding blocks which are already in the badblocks list.
1889 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1890 of the list, use a shortcut O(1) operations instead of an
1891 O(n) operation. (Idea suggested by David Beattie.)
1893 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1894 of badblocks_list_free(), to save a procedure call.
1896 1999-10-26 <tytso@valinux.com>
1898 * Release of E2fsprogs 1.17
1900 1999-10-26 <tytso@valinux.com>
1902 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1903 seem to handle ~0UL the same way as they used to.
1905 1999-10-25 <tytso@valinux.com>
1907 * nt_io.c (_OpenNtName): Open the device using
1908 FILE_SYNCHRONOUS_IO_NONALERT instead of
1909 FILE_SYNCHRONOUS_IO_ALERT
1910 (nt_open): At the end of the device open routine, unlock
1911 the drive but do not dismount it.
1913 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
1916 1999-10-22 <tytso@valinux.com>
1918 * Release of E2fsprogs 1.16
1920 1999-10-22 <tytso@valinux.com>
1922 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1924 * link.c (ext2fs_link): This call now uses the low three bits of
1925 the flags parameter to pass the directory filetype
1926 information; it will set the directory entry FILETYPE
1927 information if the filesystem supports it.
1929 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1930 option is set, then create the '.' and '..' entries with
1931 the filetype set to EXT2_FT_DIR.
1933 1999-09-24 <tytso@valinux.com>
1935 * nt_io.c: New file which supports I/O under Windows NT.
1937 1999-09-07 <tytso@valinux.com>
1939 * ext2fs.h: Add new fields for journalling and define new
1940 feature bits used by newer filesystems: IMAGIC_INODES,
1941 HAS_JOURNAL, RECOVER.
1943 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1944 we update the inode block count and size files so that the
1945 block count field is updated correctly when we create an
1948 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1950 * Release of E2fsprogs 1.15
1952 1999-06-23 <tytso@valinux.com>
1954 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1955 kernels that use i_generation instead of i_version. Patch
1956 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1958 1999-06-21 <tytso@valinux.com>
1960 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1961 directory entry before calling the callback function.
1962 This should prevent some core dumps of insufficiently
1963 paranoid callback functions.
1965 1999-05-29 <tytso@rsts-11.mit.edu>
1967 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1969 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1970 that we don't handle writing yet (we do). Fixed bug where
1971 we weren't allocating a big enough buffer for ext2_bmap.
1973 1999-05-03 <tytso@rsts-11.mit.edu>
1975 * openfs.c (ext2fs_open): Check to make sure that the number of
1976 blocks per group is not zero --- if so, it must be a bad
1979 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
1981 * Release of E2fsprogs 1.14
1983 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
1985 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
1986 the inode number is zero; if it's zero, return
1987 EXT2_ET_BAD_INODE_NUM.
1989 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
1991 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
1992 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
1995 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
1997 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
1998 non-Linux case to use EINVAL by default, unless it isn't
1999 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
2002 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
2004 * Release of E2fsprogs 1.13
2006 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
2008 * Makefile.in: Updated dependencies.
2010 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
2012 * initialize.c (ext2fs_initialize): Make sure that we allocate
2013 enough inodes so that we can make a valid filesystem.
2015 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
2017 * rw_bitmaps.c: Fixed signed/unsigned warnings.
2019 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
2020 function declaration.
2022 * dblist.c (make_dblist): Add safety check in case the dblist
2023 pointer passed in is null (in which case, assign it to
2024 fs->dblist). Fixed some signed/unsigned warnings.
2026 * bmap.c: Make addr_per_block be of type blk_t to avoid
2027 signed/unsigned warnings.
2029 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
2030 function declaration.
2032 * get_pathname.c (get_pathname_proc): Use return value from
2033 ext2fs_get_mem, instead of checking if &gp->name is
2036 * dir_iterate.c (ext2fs_process_dir_block):
2037 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
2038 from the function declaration.
2040 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
2041 return the error directly instead of jumping to the
2042 cleanup routine, since we don't need to do any cleanup.
2044 * alloc_table.c (ext2fs_allocate_group_table): Make this
2045 function take a dgrp_t for its group argument.
2047 * ext2fs.h: Make dgrp_t an __u32 type, and make
2048 fs->desc_group_count be of type dgrp_t.
2050 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
2052 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
2053 than 10 blocks when we need to expand the size of the
2056 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2058 * Release of E2fsprogs 1.12
2060 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2062 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
2063 appropriate for all of the block group copies, so that
2064 it's clear where the beginning of the filesystem is on the
2065 disk. (For when the partition table gets scrod.)
2067 * ext2fs.h: Change the name of the feature from
2068 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
2069 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
2071 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
2073 * inode.c (get_next_blockgroup): Fix bug where if
2074 get_next_blockgroup() is called early because of a missing
2075 inode table in a block group, the current_inode counter
2076 wasn't incremented correctly.
2078 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
2080 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
2081 against a completely trashed bad block inode.
2083 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
2085 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
2086 the stride length hits a bad value, we retry the block
2087 allocation starting at the beginning of the block group.
2089 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
2090 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
2091 e2_blkcnt_t to avoid collision with LFS API.
2093 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
2095 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
2096 way that avoids overflows on disk sizes greater than 4GB.
2098 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
2100 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
2101 return type for comparison functions for qsort.
2103 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
2106 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
2108 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
2111 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
2112 evade a potential problem with glibc's header files trying
2113 to spike out linux/types.h.
2115 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
2116 include the old size of the memory, which is needed for
2117 some braindamaged memory allocation systems that don't
2120 * badblocks.c (ext2fs_badblocks_list_add):
2121 bb_inode.c (clear_bad_block_proc):
2122 dblist.c (ext2fs_add_dir_block):
2123 icount.c (insert_icount_el):
2124 irel_ma.c (ima_put):
2125 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
2126 pass the old size of the memory to be resized to
2127 ext2fs_resize_mem().
2129 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2131 * Makefile.in: Change to use new installation directory variables
2132 convention. Fix uninstall rules to take $(DESTDIR) into
2135 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
2137 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
2138 with 32 bit longs, then we need to manually define __s64
2139 and __u64, since the current kernel header files don't
2140 define these if __STRICT_ANSI__ is defined. This is a
2141 problem if we are compiling with full GCC warnings, since
2142 we do need 64 bit support.
2144 * Makefile.in (OBJS): Remove bmove.o from files to be built,
2145 since we're not using ext2fs_move_blocks() and there
2146 is some question as to its usefulness in its current
2149 * bmap.c (block_bmap): Remove unused function.
2151 * bmove.c (process_block): Fix -Wall warning.
2153 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
2155 * block.c (ext2fs_block_iterate3): Make the ref_offset field
2156 contain the offset into the inode.i_blocks array when
2157 ref_block is zero. Since we haven't done a formal

2255 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
2256 so that we don't need to call get_next_blockgroup() the
2257 first time around. Saves a bit of time, and prevents us
2258 from needing to assign -1 to current_group (which is an
2261 * icount.c (insert_icount_el): Cast the estimated number of inodes
2262 from a float to an ino_t.

2304 paranoid about validating the directory counts from the
2305 block group information.
2307 * all files: Don't include stdlib.h anymore; include it in
2308 ext2_fs.h, since that file requires stdlib.h
2310 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2312 * expanddir.c (ext2fs_expand_dir): Check to make sure the block

2438 set would be, as a string of bytes, 00 00 00 01 00 ... To
2439 cope with this, we byte-reverse each word of a bitmap if
2440 we have a big-endian filesystem, that is, if we are *not*

2663 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2665 * dblist.c (ext2fs_set_dir_block): New function which sets the
2666 block of a dblist entry, given the directory inode and
2669 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2671 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
2672 inode bitmaps at staggered locations across the block
2673 groups, to avoid concentrating the bitmaps on a small
2674 number of disks when using striped RAID arrays.
2676 * initialize.c (ext2fs_initialize): By default, choose the maximum
2677 possible number of blocks per group (based on the size of
2678 the bitmaps in the blocksize).
2680 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2682 * initialize.c (ext2fs_initialize): Add support for
2683 EXT2_COMPAT_SPARSE_SUPER feature.
2685 * closefs.c (ext2fs_bg_has_super): New function to determine
2686 whether or a particular block group should have a
2687 superblock and block group descriptor. Used for the
2688 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
2689 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
2690 or not the superblock should be written out for the block
2693 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
2694 for sparse duplicate superblocks.
2696 * version.c (ext2fs_get_library_version): New function which
2697 returns the library version.
2699 * version.c (ext2fs_parse_version_string): New function which
2700 parses a version string and returns a version number,
2701 so application programs can compare version numbers as
2704 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2706 * icount.c (ext2fs_create_icount): Change function so that it also
2707 takes a new argument which contains a "hint" icount
2708 structure. This "hint" icount allows the create function
2709 to set up the sorted list in advance. This reduces
2710 significantly the amount of data moving needed to insert
2711 these inodes into the list later.
2713 * icount.c (ext2fs_icount_validate): New function which validates
2714 that the icount structure's rep invariant.
2716 * icount.c (get_icount_el): Completely revamped implementation
2717 to subsume put_icount_el(). Put_icount_el() used to
2718 use an O(N) implementation to insert in the middle
2719 of the icount list. It now uses a O(ln N) to search
2720 for where the icount should be inserted, and then uses
2721 a memcpy to move the list down (instead of a for loop).
2723 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
2724 ext2fs_icount_increment, ext2fs_icount_decrement): Check
2725 to see if the inode is within bounds; if it isn't, return
2728 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
2729 when a bad inode number is passed to test_generic_bitmap
2730 to be EXT2FS_TEST_ERROR instead of the wrong
2731 EXT2FS_UNMARK_ERROR.
2733 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
2735 * Release of E2fsprogs version 1.07
2737 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2739 * Makefile.in (ELF_VERSION): Change version to be 2.2
2741 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2743 * alloc.c (ext2fs_get_free_blocks): Change routine to use
2744 ext2fs_fast_test_block_bitmap_range().
2746 * bitops.h (ext2fs_fast_test_block_bitmap_range,
2747 ext2fs_test_block_bitmap_range: New inline functions which
2748 test to see whether a contiguous range of blocks is
2751 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2753 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
2754 use ext2fs_badblocks_* instead of badblocks_*
2756 * bb_compat.c: New file which translates between old badblocks_*()
2757 names to ext2fs_badblocks_*()
2759 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
2760 link.c (since e2fsck doesn't use ext2fs_unlink()).
2762 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
2763 bitmap resizing routine moved from bitmaps.c, since e2fsck
2764 doesn't need to use this function.
2766 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
2767 since e2fsck only needs ext2fs_lookup.
2769 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2771 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
2772 already set; this is needed so that programs like dump
2773 which use the inode scan functions will deal with
2774 filesystems that have bad blocks in the inode table.
2776 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2778 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
2779 Moved to ext2fsP.h, since it doesn't need to be part of
2780 the public interface.
2782 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
2784 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2786 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
2787 directory block list abstraction. (Code moved from
2790 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
2791 to inode.c (since no one else should be peeking inside it!)
2793 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
2795 * openfs.c (ext2fs_open): Check the feature set in the ext2
2796 superblock, and refuse to open filesystems if they contain
2797 incompatible features. (Can be overriden with the
2800 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2802 * block.c (ext2fs_block_iterate2): Added new function
2803 ext2fs_block_iterate2 which changes the function
2804 signature of the callback function to include the
2805 referencing block and offset.
2807 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
2808 ext2fs_inode_scan_goto_blockgroup which allows an
2809 application to jump to a particular block group while
2810 doing an inode scan.
2812 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2814 * dirblock.c: Include string.h, since we use memcpy().
2816 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2818 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2819 a long not an int; this doesn't matter on i386 machines,
2820 but it does on Alpha's.
2822 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2824 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2825 table pointer is NULL, then return an error indicating
2826 that the inode table is missing.
2827 (get_next_blockgroup, get_next_blocks,
2828 ext2fs_get_next_inode): Don't treat a missing inode table
2829 as permanent error. Return MISSING_INODE_TABLE, but as an
2830 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
2832 * rw_bitmaps.c (ext2fs_write_block_bitmap,
2833 ext2fs_write_inode_bitmap): If the inode or block bitmap
2834 block is zero, then don't write out the inode or block
2835 bitmap. The idea here is to avoid stomping on the
2837 (read_bitmaps): If the inode or block bitmap block is
2838 zero, then fill in that portion of the inode or block
2839 bitmap with all zeros.
2841 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
2842 blocks in inode table when the inode table size is
2843 non-standard (and can therefore span blocks).
2845 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2847 * alloc.c (ext2fs_new_block): Fix fencepost error in
2848 ext2fs_new_block; make sure we don't try to allocate the
2849 first block beyond the end of the filesystem.
2851 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2853 * inode.c (check_for_inode_bad_blocks): New function called by
2854 get_next_blocks() to avoid reading in bad blocks marked in
2855 fs->badblocks. Inodes located in bad blocks are returned
2856 by ext2fs_get_next_inode() returns the error code
2857 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
2859 * alloc_tables.c (ext2fs_allocate_tables): New function which
2860 performs the part of mke2fs's job of allocating the
2863 * test_io.c (test_close): IO manager which is used for testing
2866 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2868 * inode.c (ext2fs_get_next_inode): Separate out the function of
2869 setting up for a new block group to get_next_blockgroup().
2870 Separate out the function of reading in blocks of the
2871 inode table to get_next_blocks().
2873 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
2875 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2876 blocks to the badblock list in sorted order. This allows
2877 badblocks_list_test to be coded using a binary search for
2880 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2882 * Release of E2fsprogs version 1.06
2884 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2886 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2887 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2890 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2891 set, then only write out the master superblock.
2893 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2895 * block.c (ext2fs_block_iterate): Fixed bug which caused
2896 block_iterate to fail to handle HURD created filesystems;
2897 it tested the inode translator field before the inode was
2900 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2902 * initialize.c (ext2fs_initialize): Make sure the description for
2903 the inode bitmap is set correctly.
2905 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

2909 * Release of E2fsprogs version 1.05
2911 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

2918 * namei.c (ext2fs_namei_follow): New function which follows
2919 symbolic link (if any) at the target.
2921 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2923 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2924 for shortcut function fs->read_inode() and fs->write_inode().
2925 Added inode_cache to reduce CPU time spent in doing
2928 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
2931 * namei.c (ext2fs_follow_link): New function.
2932 (ext2fs_namei): Extended to have support for chasing
2933 symbolic links. ext2fs_namei() still returns an inode
2934 which is a symbolic link. Symbolic links are only chased
2935 while resolving the containing directory. To chase
2936 symbolic links of the final result, use
2937 ext2fs_follow_link().
2939 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2941 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2943 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2944 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

2948 * initialize.c (ext2fs_initialize): On systems where the byte
2949 order is not i386 compatible, set the swap_byte flag.
2951 * inode.c (inocpy_with_swap): Check to see if inode contains a
2952 fast symlink before swapping the inode block fields. This
2953 required adding a new argument to inocpy_with_swap to
2954 determine whether the mode field is in host order or not.
2956 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2958 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2959 the sparc, if EXT2_STD_BITOPS set, use the standard
2960 i386-compatible bitmask operations, instead on the
2961 non-standard native bitmask operators.
2963 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2965 * block.c (ext2fs_block_iterate): Cause block iterator to return
2966 the HURD translator block (along with everything else).
2967 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2968 iterator, then don't return any meta data blocks
2969 (including the HURD translator).
2971 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2973 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2975 * uuid.c: New file, containing UUID utility functions.
2977 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2979 * ext2fs.h: Add a definition of the "real" ext2 superblock.
2981 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2983 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
2985 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2987 * openfs.c (ext2fs_open): If the blocksize in the superblock is
2988 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
2989 that's a basic value that must be correct for the rest of
2990 the library to work.
2992 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
2995 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2997 * Release of E2fsprogs version 1.04

3003 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
3005 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
3006 Change the m68k bit numbering for bitmasks to match with
3007 the bit numbering used by all other ext2 implementations.

3028 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
3031 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
3033 * getsize.c (ext2fs_get_device_size): Open the device read-only
3034 when trying to determine its size.
3036 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
3038 * Release of E2fsprogs version 1.02

3044 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3045 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
3046 to avoid conflicts with with kernel include files. Also
3047 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
3050 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
3052 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c

3072 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
3075 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>

3078 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
3080 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
3082 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
3084 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
3087 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
3089 * getsize.c (ext2fs_get_device_size): Add support for reading the

3092 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3094 * getsize.c (ext2fs_get_device_size): New function that determins
3095 the size of a device. Used by mke2fs and e2fsck.
3097 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
3099 * Makefile.in (install): Install static libraries in $(ulibdir)
3100 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
3102 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
3104 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
3105 Move these functions to freefs.c.
3107 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
3108 descriptors shadow memory to keep purify quiet. (This
3109 also has the nice benefit that the unused portion of the
3110 shadow descriptors are zeroed out.)
3112 * dirblock.c (ext2fs_write_dir_block): We need to use
3113 dirent->rec_len *before* it's byteswapped to find the
3114 location of the next directory structure!
3116 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
3117 cause ext2fs_new_inode to loop infinitely if we're trying
3118 to allocate an inode in group #0 and there are no free
3119 inodes at all in the system.
3121 * closefs.c: #include <errno.h> if it exists.
3123 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

3142 file containing functions for reading and writing
3143 directory blocks (byte swapping if necesssary)
3145 * block.c (block_iterate_ind, block_iterate_dind,
3146 block_iterate_tind): Byte swap the block addresses if
3147 EXT2_SWAP_BYTES is set (and swap them back before writing
3150 * inode.c (inocpy_with_swap): New function.
3151 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
3152 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
3154 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
3155 the superblock and group descriptors before writing it out.
3157 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
3158 then set the EXT2_SWAP_BYTES and byte-swap the superblock
3159 and group descriptors.
3161 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
3162 to desp ext2 filesystem structures.
3164 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
3165 supplied by Pete A. Zaitcev so that the C language
3166 versions of these functions are more portable. They will
3167 now work on both little and big endian systems, and the
3168 assumption that 32-bit integers are used is gone.
3170 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
3171 doing byte swapping.
3173 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
3174 byte swapping should take place.
3176 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
3178 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
3179 ext2fs_compare_inode_bitmap_end): Added new file
3180 containing routines to compare bitmaps.
3182 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
3183 Added new error codes.
3185 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
3187 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
3188 if the magic number is correct, it will be allocated.
3190 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
3192 * block.c (block_iterate_ind, block_iterate_dind,
3193 block_iterate_tind): Don't recompute block_nr each loop;
3194 just increment it! Factor check of BLOCK_FLAG_APPEND out
3195 of the loop. Factor mask of BLOCK_CHANGED into changed
3196 variable out of the loop. (block_iterate_ind, in
3197 particular, gets called a lot, so every little
3198 optimization helps.)
3200 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
3202 * block.c (block_iterate_ind, block_iterate_dind,
3203 block_iterate_tind): Precompute limit of loop to speed up
3204 block_iterate_ind and company.
3206 * bitops.h (ext2fs_fast_mark_block_bitmap,
3207 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
3208 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
3209 ext2fs_fast_test_inode_bitmap): Add fast version of these
3210 functions, which don't do range checking.
3212 * bitops.h (ext2fs_get_block_bitmap_start,
3213 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
3214 ext2fs_get_inode_bitmap_end): Add new accessor functions
3215 which return the start and end points of the bitmaps.
3217 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
3219 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
3220 instead of llseek. The errno if the offset is too large
3221 and lseek is not supported should be EINVAL, not -EINVAL.
3223 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
3225 * Makefile.in: Added support for ELF shared libraries.
3226 Fixed typos in the compilation rules.
3227 (distclean): Added Makefile.
3229 * llseek.c (llseek): New function, if llseek() does not exist in the
3231 (ext2_llseek): Changed to call llseek().
3233 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3235 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
3237 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3239 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
3241 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
3242 the S_*, which are normally defined in <sys/stat.h>. This
3243 allows us to compile e2fsprogs on a non-Linux system,
3244 which may have a different value for S_IFDIR.
3246 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3248 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
3249 this is a user-mode application!
3251 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
3253 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
3254 __linux__ so that non-linux systems won't see it.
3256 * alloc.c: Include <errno.h> if possible.
3257 * badblocks.c: Ditto.
3258 * bb_inode.c: Ditto.
3261 * expanddir.c: Ditto.
3262 * get_pathname.c: Ditto.
3263 * initialize.c: Ditto.
3270 * rw_bitmaps.c: Ditto.
3273 * Makefile.in: Rewritten to conform to GNU coding standards and
3274 support separate compilation directories.
3276 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
3278 * initialize.c (ext2fs_initialize): Don't allow more than one
3279 bitmaps's worth of inodes in a group.
3281 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
3283 * llseek.c (ext2_llseek): Added error checking to the llseek()
3284 compat code to protect against overflow. This only
3285 applies to 1.0 and early 1.1 kernels, which don't support
3286 the llseek() system call.
3288 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
3290 * unix_io.c (unix_open): Initialize the read_error and write_error
3291 io_channel pointers to be null.
3293 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
3294 found, clear it but don't try to update the filesystem
3295 accounting information, since that's hopeless anyway.
3297 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
3298 bloblock_iterate_tind): Check to see if the indirect blocks are
3299 valid before trying to read them.
3301 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
3302 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
3304 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
3305 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
3306 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
3307 illegal block or inode number is passed in, return instead
3308 of trying to test, set, or clear the bit.
3310 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
3312 * Makefile: Added a dummy install target in case shared libraries
3315 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
3317 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
3318 the real last block of the bitmap should be calculated.
3320 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
3322 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
3323 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
3324 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
3325 ext2fs_free_block_bitmap): Add magic number checking for
3326 the inode and block bitmaps.
3328 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
3329 magic number for a block bitmap instead of an inode bitmap.
3331 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
3332 magic number checking for the inode_scan structure.
3334 * badblocks.c (badblocks_list_free, badblocks_list_add,
3335 badblocks_list_test, badblocks_list_iterate_begin,
3336 badblocks_list_iterate, badblocks_list_iterate_end): Add
3337 magic number checking for the badblocks_list and
3338 badblocks_iterate structures.
3340 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
3341 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
3342 unix_write_blk, unix_flush): Add magic number checking
3343 both for io_channel structure and unix_private_data
3346 * openfs.c (ext2fs_open): Add check for io_manager structure's
3349 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
3350 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
3351 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
3352 * read_bb.c (ext2fs_read_bb_inode):
3353 * read_bb_file.c (ext2fs_read_bb_FILE):
3354 * newdir.c (ext2fs_new_dir_block):
3355 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
3356 * link.c (ext2fs_link, ext2fs_unlink):
3357 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

3362 * block.c (ext2fs_block_iterate):
3363 * bitmaps.c (ext2fs_allocate_inode_bitmap,
3364 ext2fs_allocate_block_bitmap):
3365 * bb_inode.c (ext2fs_update_bb_inode):
3366 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
3367 * check_desc.c (ext2fs_check_desc):
3368 * closefs.c (ext2fs_close, ext2fs_flush):
3369 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
3374 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
3375 openfs.c into its own file.
3377 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
3378 structure magic numbers.
3380 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
3381 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
3382 someone uses the -b option to specify the use of the backup
3383 superblock --- this usually means that the main superblock is
3387 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
3388 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
3389 revision level to the superblock.
3391 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
3398 * initialize.c: Completely revamped the inode and block bitmap
3399 structures, so that they can be better chance of being extensible
3400 in a shared library. They are now their own type, instead of
3401 being a char *. Also, the function signatures of
3402 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
3403 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
3404 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
3405 changed to eliminate the ext2_filsys argument, since it is no
3408 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
3410 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
3411 system call if available.
3413 * llseek.c: new file. This is the stub calling the llseek system
3414 call which allows supports for 2GB+ file systems.
3416 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
3417 the creator operating system.
3419 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
3421 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
3422 the group descriptor statistics in addition to everything else.
3423 This relieves mke2fs of the responsibility of doing it.
3425 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
3426 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
3427 not the generic C function equivalents should be included or not.
3429 * openfs.c (ext2fs_open): If a superblock is specified, then use
3430 the backup group descriptors that go along with this superblock,
3431 instead of using the primary group descriptors. This allows
3432 e2fsck to recover filesystems where the primary group descriptors
