1 2006-04-09 Theodore Ts'o <tytso@mit.edu>
3 * ext2_types.h.in, Makefile.in, tst_types.c: Use the asm_types.h
4 file to define the __[us]{8,16,32,64} types. Add a
5 tst_types program to make sure the types are correct.
7 2006-04-04 Theodore Ts'o <tytso@mit.edu>
9 * mkjournal.c (ext2fs_add_journal_inode): If the filesystem is
10 opened in exclusive mode, then device will be busy by
11 definition, so don't return -EBUSY. This caused mke2fs -j
12 to fail on the 1.39-WIP (29-Mar-2006) release. (Addresses
15 2006-03-29 Theodore Ts'o <tytso@mit.edu>
17 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit): Fix the constraints
18 so that GCC knows that the ext2fs_set/clear_bit reads and
21 2006-03-25 Theodore Ts'o <tytso@mit.edu>
23 * Makefile.in: Check the bitfield operations much more carefully,
24 and arrange to have tst_bitops run from "make check"
26 * tst_bitops.c: Enahce tst_bitops program so that it is much more
27 thorough in testing bit optations.
29 * bitops.h: Add new functions ext2fs_fast_set_bit() and
30 ext2fs_fast_clear_bit() and make the x86 functions 32-bit
31 clear. Change the fast inode and block mark/unmark
32 functions to use ext2fs_fast_set/get_bit()
34 2006-03-18 Theodore Ts'o <tytso@mit.edu>
36 * ext2fs.h (EXT2_FLAG_EXCLUSIVE): Define new flag which requests
37 that the io_channel be opened in exclusive mode.
39 * openfs.c (ext2fs_open2), initialize.c (ext2fs_initialize): If
40 EXT2_FLAG_EXCLUSIVE is passed to ext2fs_open or
41 ext2fs_initialize, then pass IO_FLAG_EXCLUSIVE to the
42 io_channel open routine.
44 * ext2_io.h (IO_FLAG_EXCLUSIVE), unix_io.c (unix_open): Add new
45 io_channel open flag, IO_FLAG_EXCLUSIVE, which requests
46 that the device be opened in exclusive (O_EXCL) mode.
48 * ext2fs.h: Fix documentation so that BLOCK_FLAG_TRAVERSE is
49 BLOCK_FLAG_DEPTH_TRAVERSE. (Addresses Debian Bug #351268)
51 2006-03-17 Theodore Ts'o <tytso@mit.edu>
53 * initialize.c (calc_reserved_gdt_blocks): Fix a signed vs
54 unsigned problem which caused mke2fs -O resize_inode to
55 bomb out on large filesystems. (Addresses Debian Bug
58 * ext2_fs.h (EXT2_IOC_GETVERSION_NEW, EXT2_IOC_SETVERSION_NEW,
59 EXT2_IOC_GROUP_EXTEND, EXT2_IOC_GROUP_ADD): Add ioctl
62 2005-12-10 Theodore Ts'o <tytso@mit.edu>
64 * Makefile.in: Add a dependency to make sure that the
65 subdirectories are created before creating all of the
68 2005-12-10 Theodore Ts'o <tytso@mit.edu>
70 * res_gdt.c (ext2fs_create_resize_inode): Fix type-punning warning.
72 * read_bb_file.c (ext2fs_read_bb_FILE): Use a data structure
73 instead of stuffing a function pointer dirctly into a void
74 pointer, since that isn't portable.
76 * mkjournal.c (ext2fs_add_journal_inode): Fix possiblely
77 uninitialized use of variable warning.
79 * initialize.c (calc_reserved_gdt_blocks): Fix signed vs. unsigned
82 * ext2fs.h: Make the type of the 'now' field to be time_t to avoid
85 * bitops.h (ext2fs_find_first_bit_set): Fix signed vs unsigned
88 * tst_badblocks.c (file_test_invalid): Add test which confirms
89 proper detection of invalid block numbers in
90 ext2fs_read_bb_FILE().
92 2005-11-20 Theodore Ts'o <tytso@mit.edu>
94 * bitops.h: We no longer have the sparc assembly code in the
95 header file any more, so we shouldn't set
96 _EXT2_HAVE_AS_BITOPS_. This would break compiles on the
97 sparc architectures when using gcc.
99 2005-11-13 Theodore Ts'o <tytso@mit.edu>
101 * ext2fs.h: Add #include <string.h> since the inline functions use
102 memcpy(). (Addresses Sourceforge Bug #1251062)
104 2005-11-09 Theodore Ts'o <tytso@mit.edu>
106 * Fix a bug when writing an external journal device on an big
107 endian machine (such as a S/390), where when the number of
108 block groups is zero, we never end up writing out the
109 primary superblock at all.
111 2005-09-24 Theodore Ts'o <tytso@mit.edu>
113 * ext2fs.h, bb_inode.c, closefs.c, initialize.c, mkdir.c,
114 mkjournal.c, res_gdt.c: If fs->now is non-zero, use that
115 as the time instead of the system time when setting
116 various filesystem fields (last modified time, last write
119 2005-08-28 Matthias Andree <matthias.andree@gmx.de>
121 * Fix compiler warnings about missing memcpy prototypes.
123 2005-07-25 Theodore Ts'o <tytso@mit.edu>
125 * test_io.c (safe_getenv): Pass in zero to the unusued arguments
126 of prctl(PR_GET_DUMPABLE) to avoid false positives from
129 2005-07-19 Theodore Ts'o <tytso@mit.edu>
131 * mkjournal.c (ext2fs_add_journal_inode): Check for the case where
132 the filesystem is apparently not mounted, but the device
133 is still busy. This can happen when the luser doesn't
134 bother to mount /proc and has a bogus /etc/mtab, but still
135 wants to mount the filesystem before using tune2fs(?!?).
136 Add a safety check to save him from his own stupidity, at
137 least on 2.6 kernels. (Addresses Debian Bug #319002)
139 2005-07-09 Andreas Dilger <adilger@clusterfs.com>
141 * getsize.c (ext2fs_get_device_size): Use fstat/fstat64 to get
142 size of regular files. Fix file descriptor leaks in error
145 2006-06-30 Theodore Ts'o <tytso@mit.edu>
147 * Release of E2fsprogs 1.38
149 2005-06-30 Theodore Ts'o <tytso@mit.edu>
151 * bitops.h, bitops.c (ext2fs_set_bit, ext2fs_clear_bit,
152 ext2fs_test_bit): Change these function prototypes to be
153 unsigned int's. Negative bit numbers were never allowed
154 (and never made any sense), so this should be a safe
155 change. This is needed to allow safe use of block numbers
156 greater than or equal to 2**31.
158 2005-06-27 Stephen Tweedie <sct@redhat.com>
160 * ext2fs.h (ext2fs_resize_mem): Fix C99 strict type aliasing
161 problems. Addresses Red Hat Bugzilla #161183.
163 2005-06-19 Theodore Ts'o <tytso@mit.edu>
165 * getsectsize.c (BLKSSZGET): Clean up test for when to manually
166 define the BLKSSZGET ioctl.
168 2005-05-29 Theodore Ts'o <tytso@mit.edu>
170 * ismounted.c (ext2fs_check_mount_point): Add test to see if the
171 device appears to be busy; this only works on Linux 2.6+
172 systems, but provides some additional bullet-proofing in
175 2005-05-08 Theodore Ts'o <tytso@mit.edu>
177 * test_io.c (safe_getenv): Fix bug so it would fetch the right
178 environment variable.
180 2005-04-09 Theodore Ts'o <tytso@mit.edu>
182 * inode.c (ext2fs_write_new_inode),
183 ind_block.c (ext2fs_read_ind_block): Add missing return
184 value in error return case. (Otherwise we return garbage
185 instead of the error code.)
187 2005-03-31 Theodore Ts'o <tytso@mit.edu>
189 * test_io.c (test_open): If called by a setuid/setgid or an
190 otherwise privileged program, be paranoid and ignore the
191 TEST_IO_* environment variables.
193 2005-03-21 Theodore Ts'o <tytso@mit.edu>
195 * Release of E2fsprogs 1.37
197 2005-03-21 Theodore Ts'o <tytso@mit.edu>
199 * ext2_ext_attr.h (EXT2_XATTR_LEN, EXT2_XATTR_SIZE): Add new
200 convenience cpp macros.
202 2005-03-20 Theodore Ts'o <tytso@mit.edu>
204 * mkdir.c (ext2fs_mkdir): Call ext2fs_write_new_inode() instead of
205 ext2fs_write_inode().
207 * inode.c (ext2fs_write_new_inode): New function which should be
208 used when the caller is writing an inode for the first
209 time. It makes sure that the extra portion of the large
210 inode is initialized properly.
212 2005-03-18 Theodore Ts'o <tytso@mit.edu>
214 * Makefile.in: Fix clean target to remove tst_getsectsize.
216 * getsize.c (ext2fs_get_device_size): Check to see if the number
217 of blocks is greater than 2**32 when we are doing a binary
218 search to determine the device size. Thanks to Stephen
219 Tweedie for the patch.
221 2006-02-05 Theodore Ts'o <tytso@mit.edu>
223 * Release of E2fsprogs 1.36
225 2005-02-05 Theodore Ts'o <tytso@mit.edu>
227 * Makefile.in: Remove ext2fs.pc on a "make distclean"
229 2005-02-04 Theodore Ts'o <tytso@mit.edu>
231 * Makefile.in (clean): Remove tst_getsize when doing a make clean
233 2005-02-03 Theodore Ts'o <tytso@mit.edu>
235 * bitops.c: Make the generic functions more efficient.
237 * bitops.h: Drop SPARC assembly code. It's less efficient than GCC
238 3.4 compiled code and also triggers nasty compiler
239 warnings on sparc64. Thanks to Matthias Andree for his
240 analysis and suggestion.
242 2005-01-27 Theodore Ts'o <tytso@mit.edu>
244 * res_gdt.c (ext2fs_create_resize_inode): Create the resize inode
245 even if s_reserved_gdt_blocks is zero.
247 2005-01-26 Theodore Ts'o <tytso@mit.edu>
249 * ext2fs.pc.in: Add pkg-config files.
251 2005-01-25 Theodore Ts'o <tytso@mit.edu>
253 * ext2fs.h: Add definition of struct ext2_inode_large
255 * ext2_fs.h: Add new function prototypes
257 * ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr): The
258 ext2fs_swap_ext_attr() has been moved to swapfs.c, and
259 given a new argument, has_header.
261 * swapfs.c (ext2fs_swap_ext_attr): Moved from ext_attr.c, and
262 takes an argument which controls whether or not there is
263 an EA header which needs to be byteswaped.
264 (ext2fs_swap_inode_full): New function which byte-swaps
267 * inode.c (ext2fs_get_next_inode_full, ext2fs_read_inode_full,
268 ext2fs_write_inode_full): New functions, originally from
269 Alex Tomas, but which needed to be substantially fixed so
270 that the tests wouldn't cause major stack overwrite bugs
271 in byte-swapping is enabled.
273 2005-01-18 Theodore Ts'o <tytso@mit.edu>
275 * Makefile.in: Fix the kernel compile-time echo commands to be
276 consistent and portable
278 2005-01-07 Theodore Ts'o <tytso@mit.edu>
280 * unlink.c (ext2fs_unlink): If both the name and the inode number
281 are unspecified, then return an error, so that we don't do
282 something surprising such as unconditionally deleting the
283 first directory entry.
284 (unlink_proc): Delete directory entries by coalescing it
285 with the previous entry, to avoid directory fragmentation.
287 2005-01-06 Theodore Ts'o <tytso@mit.edu>
289 * version.c (ext2fs_parse_version_string): Change parsing
290 algorithm so that version strings such as 1.36-rc1 returns
291 a non-surprising result (i.e., 136, and not 1361).
293 2005-01-05 Theodore Ts'o <tytso@mit.edu>
295 * block.c (block_iterate_ind, block_iterate_dind,
296 block_iterate_tind): Move the code which byte swaps and
297 read/writes indirect blocks to ext2fs_{read,write}_ind_block.
298 This saves 400 bytes, and we need them for the
299 resize_inode handling.
301 * ind_block.c (ext2fs_read_ind_block, ext2fs_write_ind_block): New
304 * res_gdt.c (ext2fs_create_resize_inode): Use
305 ext2fs_{read,write}_ind_block so that byte swapping is
306 handled on big-endian systems.
308 * dupfs.c (ext2fs_dup_handle): Make sure the new filesystem handle
309 has its own copy of the orig_super data structure. (This
310 is a better way of fixing a double-free problem in
311 resize2fs which Fedora attempted to fix in
312 e2fsprogs-1.35-double_free.patch. Addresses Red Hat
315 2004-12-23 Theodore Ts'o <tytso@mit.edu>
317 * inode.c (ext2fs_flush_icache): When flushing the icache, clear
318 the last-read block information as well.
320 * ext2fs.h (BMAP_SET), bmap.c (ext2fs_bmap): Add support for new
321 flag, BMAP_SET, which allows the caller to set a
322 particular logical->physical block mapping.
324 * ext2_err.et.in (EXT2_ET_SET_BMAP_NO_IND): New error code
326 * initialize.c (calc_reserved_gdt_blocks): #ifdef out all
327 debugging printf statements.
329 * res_gdt.c (ext2fs_create_resize_inode): Return
330 EXT2_ET_RESIZE_INODE_CORRUPT if the resize inode is not
331 what we expect. #ifdef out all debugging printf
334 * ext2_err.et.in (EXT2_ET_RESIZE_INODE_CORRUPT): Add new error code.
336 2004-12-22 Theodore Ts'o <tytso@mit.edu>
338 * swapfs.c (ext2fs_swap_super): Byteswap the reserved_gdt_blocks
341 2004-12-15 Theodore Ts'o <tytso@mit.edu>
343 * sparse.c (ext2fs_list_backups, ext2fs_bg_has_super),
344 res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
345 ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
346 ext2fs_bg_has_super() back to closefs.c. There's no
347 reason for the new file, since list_backups() isn't being
348 used by any other functions, and can be made static, and
349 all users of the ext2fs filesystem will have to call
350 ext2fs_close() anyway.
352 2004-12-15 Theodore Ts'o <tytso@mit.edu>
354 * Applied resize inode patch from Andreas Dilger
356 * res_gdt.c (ext2fs_create_resize_inode): New function that
357 creates the resize inode.
359 * initialize.c (ext2fs_initialize): Reserve space for the resize
362 * ext2fs.h (EXT2_LIB_FEATURE_COMPAT_SUPP): Add
363 EXT2_FEATURE_COMPAT_RESIZE_INODE to the list of supported
365 Add function prototypes for res_gdt.c and sparse.c.
367 * closefs.c (ext2fs_super_and_bgd_loc): Take the reserved blocks
368 into account when calculating the number of overhead
371 * closefs.c (ext2fs_bg_has_super, test_root), sparse.c: Move these
372 functions to the new file sparse.c
374 * alloc_sb.c (ext2fs_reserve_super_and_bgd): Reserve the blocks
375 saved in the resize inode as being in use.
377 * ext2_err.et.in (EXT2_ET_RES_GDT_BLOCKS): Add new error code.
379 * Makefile.in (srcdir): Add res_gdt.c and sparse.c to the ext2fs
382 2004-12-14 Theodore Ts'o <tytso@mit.edu>
384 * Makefile.in: Use Linux-kernel-style makefile output for "make
387 * Makefile.in (installdirs): Use $(MKINSTALLDIRS) macro
390 2004-11-30 Theodore Ts'o <tytso@mit.edu>
392 * unix_io.c (unix_set_option): Add support for the offset option.
394 * test_io.c (test_set_option): Add support for the set_option method.
396 * ext2_io.h: Add new io_channel method, set_option(), and change
397 io_channel_write_byte() from a macro to a library function.
399 * ext2fs.h, openfs.c(ext2fs_open2): New version of ext2fs_open
400 which adds a new parameter, io_options.
401 (ext2fs_open): If there is a question mark in the
402 filename, and no io_options are specified, assumed that
403 the text following the question mark are io_options.
405 * io_manager.c, Makefile.in: New source file which contains
406 high-level functions for the io_channel layer.
408 * freefs.c (ext2fs_free): Make sure we don't free the io_channel
411 * Makefile.in: Use Linux-kernel-style makefile output to make it
412 easier to see errors/warnings.
414 2004-11-29 Theodore Ts'o <tytso@mit.edu>
416 * ext2_fs.h (EXT2_EXTENTS_FL, EXT3_FEATURE_INCOMPAT_EXTENTS,
417 EXT2_MAX_BLOCK_LOG_SIZE): Add definition for extent
418 feature and inode flag. Change maximum allowable block
421 2004-10-08 Theodore Ts'o <tytso@mit.edu>
423 * getsize.c (ext2fs_get_device_size): Add support for Windows
424 9x/NT under Cygwin. Thanks to Sam Robb
425 (samrobb@users.sourceforge.net) for pointing this and the
426 suggested code patch.
428 2004-09-17 Theodore Ts'o <tytso@mit.edu>
430 * getsize.c: Clean up header #include's.
432 * llseek.c (ext2fs_llseek): On non-linux systems, use lseek64() if
433 it is present. (Addresses Debian bug #269044)
435 2004-07-28 Theodore Ts'o <tytso@mit.edu>
437 * rw_bitmaps.c (read_bitmaps), block.c (block_iterate_ind,
438 block_iterate_dind, block_iterate_tind), inode.c
439 (ext2fs_read_inode): If EXT2_FLAG_IMAGE_FILE is set, so
440 read the metadata from fs->image_io instead of fs->io.
442 * initialize.c (ext2fs_initialize), openfs.c (ext2fs_open):
443 Initialize fs->image_io to be the same as fs->io.
445 * ext2_err.et.in (EXT2_ET_NOT_IMAGE_FILE): Add new error code.
447 * openfs.c (ext2fs_get_data_io, ext2fs_set_data_io,
448 ext2fs_rewrite_to_io): New functions that allow
449 applications to manipulate fs->image_io and fs->io safely.
451 * freefs.c (ext2fs_free): If fs->image_io is different fs->io,
452 then call io_channel_close on fs->image_io.
454 * ext2fs.h: Add image_io element to the ext2_filsys data
455 structure. Add ext2fs_get_data_io() ext2fs_set_data_io(),
456 and ext2fs_rewrite_to_io() prototypes.
458 2004-05-26 Theodore Ts'o <tytso@mit.edu>
460 * closefs.c (ext2fs_flush): Make sure the master superblock is
461 written last, and only after other I/O has been flushed to
462 disk. Thanks to Junfeng Yang from the Stanford
463 Metacompilation group for pointing a potential ordering
464 constraint problem if we don't write things out in the
467 * test_io.c: Implement the ability to abort after n reads or
468 writes to a particular block. The block is specified by
469 TEST_IO_BLOCK environment variable, and the read/write
470 count by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT
471 environment variables. The block data is now only dumped
472 if the 0x10 bit is set in TEST_IO_FLAGS.
474 2004-04-03 Theodore Ts'o <tytso@mit.edu>
476 * ext2_types.h.in: Remove check for _UUID_TYPES since uuid_types.h
479 2004-03-08 Theodore Ts'o <tytso@mit.edu>
481 * getsize.c (ext2fs_get_device_size): Only use the BLKGETSIZE64
482 ioctl on Linux 2.6 since it is unreliable in Linux 2.4.
483 (Addresses Debian Bug #236528). Fix typo in the ioctl
486 2004-03-02 Theodore Ts'o <tytso@mit.edu>
488 * getsize.c (ext2fs_get_device_size): Update getsize functions to
489 use Apple Darwin and Linux 64-bit ioctl's
491 2004-02-29 Brian Bergstrand <brian@bergstrand.org>
493 * Makefile.in: Use $(BSDLIB_PIC_FLAG) to determine whether to use
496 2004-02-28 Theodore Ts'o <tytso@mit.edu>
498 * Release of E2fsprogs 1.35
500 2004-02-21 Theodore Ts'o <tytso@mit.edu>
502 * ext2fs.h (ext2fs_resize_mem): Fix C++ problem. (Addresses Red
503 Hat Bugzilla #112448; thanks Thomas Woerner from Red Hat.)
505 2004-02-14 Theodore Ts'o <tytso@mit.edu>
507 * namei.c (follow_link): Correctly deal with symlinks that have
508 extended attribute information. (Addresses Debian Bug
511 2004-01-30 Theodore Ts'o <tytso@mit.edu>
513 * ext2_fs.h: Reserve an extra 4 bytes for the journal backup,
514 which we're using due to a typo in the e2fsck code. (Oops)
516 * swapfs.c (ext2fs_swap_inode): Fix byte swap bug which causes SE
517 Linux created symlinks with mandatory attributes to fail
518 to be properly handled on big endian systems. (Addresses
520 (ext2fs_swap_super): Byte swap some new fields in the
521 superblock, including the journal backup fields.
523 2003-12-02 Theodore Ts'o <tytso@mit.edu>
525 * alloc.c, bb_inode.c, bitops.c, block.c, check_desc.c, closefs.c,
526 dir_iterate.c, dirblock.c, expanddir.c, ext2fs.h,
527 get_pathname.c, icount.c, imager.c, initalize.c, inode.c,
528 lookup.c, openfs.c, read_bb.c, read_bb_file.c,
529 rw_bitmaps.c, unix_io.c, unlink.c, write_bb_file.c: Fix
530 gcc -Wall complaints. Mainly marking variables as being
531 unsued, and catching signed vs. unsigned comparisons.
533 2003-09-03 Theodore Ts'o <tytso@mit.edu>
535 * closefs.c (ext2fs_super_and_bgd_loc): New function which
536 centralizes the calculation of the superblock and block
538 (ext2fs_flush): Use ext2fs_super_and_bgd_lock to figure
539 out where to write the superblock and block group
542 * alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
543 reserves space in the block bitmap using
544 ext2fs_super_and_bgd_loc.
546 * initialize.c (ext2fs_initialize): Use
547 ext2fs_reserve_super_and_bgd to initialize the block bitmap.
549 2003-08-20 Theodore Ts'o <tytso@mit.edu>
551 * inode_io.c (ext2fs_inode_io_intern2), ext2fs.h: Add new function
552 allows the caller to pass in the inode data structure.
554 * fileio.c (ext2fs_file_open2), ext2fs.h: Add new function which
555 allows the caller to pass in the inode to be used in the

572 rw_bitmaps.c, test_io.c, unix_io.c: ext2fs_getmem(),
573 ext2fs_free_mem(), and ext2fs_resize_mem() all now take a
574 'void *' instead of a 'void **' in order to avoid pointer
575 aliasing problems with GCC 3.x.
577 2003-07-25 Theodore Ts'o <tytso@mit.edu>
579 * Release of E2fsprogs 1.34
581 2003-07-06 Theodore Ts'o <tytso@mit.edu>
583 * kernel-jbd.h, flushb.c: Fix gcc -Wall nitpicks (indented cpp
586 * ext2_types.h.in, initialize.c: Fix gcc -Wall nitpicks
589 * ismounted.c: Fix gcc -Wall nitpicks (Don't use exit as a goto label)
591 * llseek.c: Fix gcc -Wall nitpicks (don't use #elsif)
593 * lookup.c, read_bb.c: Fix gcc -Wall nitpicks (indent
594 non-traditional #pragma)
596 * test_io.c: Fix gcc -Wall nitpicks (const/unsigned type issues)
598 2003-06-24 <tytso@snap.thunk.org>
600 * badblocks.c, ext2fs.h (ext2fs_u32_list_find,
601 ext2fs_u32_list_test, ext2fs_u32_list_del,
602 ext2fs_badblocks_list_del): Add functions to delete a
603 block from the badblocks list.
604 * tst_badblocks.c: Add test cases for ext2fs_badblocks_list_del().
606 2003-05-21 Theodore Ts'o <tytso@mit.edu>
608 * getsectsize.c (ext2fs_get_device_sectsize): New function which
609 returns the hardware sector size (if it is available).
611 2003-05-13 Theodore Ts'o <tytso@mit.edu>
613 * unix_io.c: Add #ifdef NO_IO_CACHE which disables all userspace
614 caching by the unix_io layer. Not enabled, only for
617 2003-05-05 Theodore Ts'o <tytso@mit.edu>
619 * test_io.c: Pay attention to the environment variables
620 TEST_IO_LOGFILE, TEST_IO_FLAGS, and TEST_IO_BLOCK to
621 determine whether or not we should log io activity, and to
624 2003-05-03 Theodore Ts'o <tytso@mit.edu>
626 * tst_badblocks.c (file_test): Use tmpfile() instead of mktemp().
628 2003-04-29 Theodore Ts'o <tytso@mit.edu>
630 * getsize.c (ext2fs_get_device_size): Allow windows code to get
631 the resize for filesystems that are in regular files.
633 2003-04-21 Theodore Ts'o <tytso@mit.edu>
635 * Release of E2fsprogs 1.33
637 2003-04-21 Theodore Ts'o <tytso@mit.edu>
639 * Makefile.in: Use DYLD_LIBRAY_PATH so that "make check" works on
640 Darwin systems when building with shared libraries.
642 2003-04-18 Theodore Ts'o <tytso@mit.edu>
644 * unix_io.c: Use __CYGWIN__ instead of CYGWIN.
646 2003-04-17 Theodore Ts'o <tytso@mit.edu>
648 * getsize.c: Add Cygwin/Windows version of ext2fs_get_device_size()
650 2003-04-12 Theodore Ts'o <tytso@mit.edu>
652 * unix_io.c (raw_read_blk): Add Cygwin support (the Windows block
653 device only accepts sector aligned read requests.
655 * ismounted.c (check_mntent_file): Deal with OS's that don't
658 * imager.c: If the OS doesn't define ssize_t, typedef it to int.
660 2003-04-11 Theodore Ts'o <tytso@mit.edu>
662 * ext2_fs.h (EXT2_FEATURE_RO_COMPAT_BTREE_DIR): Comment out unused
665 2003-03-30 Theodore Ts'o <tytso@mit.edu>
667 * Makefile.in: Use the compile_et --build-tree option.
669 2003-03-14 Theodore Ts'o <tytso@mit.edu>
671 * getsize.c: Add support for Apple Darwin's ioctl to get the hard
674 * badblocks.c (ext2fs_u32_list_count), ext2fs.h: Add new function
675 which returns the number of entries in the list.
677 2003-03-10 Theodore Ts'o <tytso@mit.edu>
679 * fileio.c (ext2fs_file_lseek): Fix bug added when adding 64-bit
680 support; avoid null dereference when ret_pos is NULL.
682 2003-03-06 Theodore Tso <tytso@mit.edu>
684 * ext2_types.h.in: Don't redefine types if other e2fsprogs
685 *_types.h files have been included already.
687 * kernel-jbd.h: Use C99 variadic cpp macros if not using GCC.
688 (Older GCC's don't support the C99 variadic macros.)
690 * flushb.c (ext2fs_sync_device),
691 ismounted.c (ext2fs_check_mount_point): Avoid GCC extension:
692 #warning not supported by Solaris suncc
694 * ext2_ext_attr.h: Avoid GCC extension: 0 length arrays in
695 structure definition. Not needed for now in
698 2003-01-25 Theodore Ts'o <tytso@mit.edu>
700 * dirhash.c: Fix gcc -Wall nits.
702 2003-01-22 Theodore Ts'o <tytso@mit.edu>
704 * unix_io.c (unix_write_blk): Fix up GCC -Wall nits.
706 2003-01-21 Theodore Ts'o <tytso@mit.edu>
708 * fileio.c (ext2fs_file_read, ext2_file_lseek,
709 ext2_file_get_size): Add 64-bit support.
711 * ext2fs.h (EXT2_I_SIZE): Add macro which caluates a 64bit size
712 from i_size and i_size_high.
714 2003-01-19 Theodore Ts'o <tytso@mit.edu>
716 * initialize.c (ext2fs_initialize): If the user specifies a really
717 large number of inodes, then reduce the number of blocks
718 per group until we find a workable set of filesystem
721 * ext2_err.et.in (EXT2_ET_TOO_MANY_INODES): Add new error code.
723 2002-11-09 Theodore Ts'o <tytso@mit.edu>
725 * Release of E2fsprogs 1.32
727 2002-11-09 Theodore Ts'o <tytso@mit.edu>
729 * unix_io.c (find_cached_block, reuse_cache, unix_read_blk,
730 unix_write_blk): Optimize routines so that we don't end up
731 searching the cache twice when a block isn't in the
732 cache. If reads are larger than READ_DIRECT_SIZE, don't
733 let them go through the cache.
735 * unix_io.c (find_cached_block): Fixed bug which caused some clean
736 blocks to be erroneously marked as dirty, so they would
737 get written back to the disk before they are evicted from
738 the cache. Harmless, but it slows down e2fsck
741 2002-11-08 Theodore Ts'o <tytso@mit.edu>
743 * Release of E2fsprogs 1.31
745 2002-11-08 <tytso@snap.thunk.org>
747 * Makefile.in (check): Skip trying to compile test_byteswap
748 if --disable-byteswaap had been given to configure.
750 2002-11-07 <tytso@snap.thunk.org>
752 * closefs.c (write_bgdesc, ext2fs_flush): Fix bug in meta_bg
753 support when the MASTER_SB_ONLY flag is set. Some of
754 the descriptor blocks that should have been written out
755 were getting skipped.
757 2002-10-31 Theodore Ts'o <tytso@mit.edu>
759 * Release of E2fsprogs 1.30
761 2002-10-31 Theodore Ts'o <tytso@mit.edu>
763 * ext2_fs.h: Add support for a new inode flag, which is to be used
764 for indicating the top of directory hierarchies for the
765 Orlov block allocator.
767 * ismounted.c (check_mntent, check_mntent_file): Add better
768 support for loopback-mounted filesystems. Check /etc/mtab
769 if /proc/mounts doesn't turn up any mount flags, since
770 /etc/mtab has the loopback image filename, instead of
771 /dev/loop0. Also, check based on st_dev and st_ino, so
772 that if a relative pathname or a pathnames using symbolic
773 links are used, we can detect the the filesystem correctly
774 in those cases. (Addresses Sourceforge bug #619119)
776 * flushb.c (ext2fs_sync_device): If the BLKFLSBUF ioctl succeeds,
777 don't try the FDFLUSH ioctl that was required for floppies
778 with older kernels. This avoids needless whining from the
779 MD device driver. (Addresses Sourceforge bug #545832).
781 * openfs.c (ext2fs_open): Fix bug which caused us to pass the
782 wrong group_block to ext2fs_descriptor_block_loc if we're
783 using the backup superblock/block group descriptors.
784 (ext2fs_descriptor_block_loc): If we're using the backup
785 superblock descriptors, use the backup descriptor block in
786 the next block group.
788 2002-10-30 Theodore Ts'o <tytso@mit.edu>
790 * alloc_tables.c (ext2fs_allocate_group_table): Allocate the inode
791 table so that it buts up against the bitmap blocks, to
792 avoid block fragmentation.
794 * closefs.c (write_bgdesc), initalize.c (ext2fs_initialize): Fix
795 bug; only allocate group descriptor blocks up to
798 2002-10-25 Theodore Ts'o <tytso@mit.edu>
800 * ext2_fs.h: Add a new superblock field, s_mkfs_time, so that we
801 know when a filesystem was created. (Sometimes this can
804 * initialize.c (ext2fs_initialize): Set the s_mkfs_time field.
806 2002-10-20 Theodore Ts'o <tytso@valinux.com>
808 * ext2_fs.h (EXT3_DEFM_JMODE): Add new default mount options for
809 the journal data mode.
811 * closefs.c (ext2fs_flush, write_bgdesc), ext2_fs.h, ext2fs.h,
812 openfs.c (ext2fs_descriptor_block_loc, ext2fs_open), initialize.c
813 (ext2fs_initialize), swapfs.c (ext2fs_swap_super): Add support for
814 the meta_blockgroup filesystem format.
816 2002-10-15 <tytso@snap.thunk.org>
818 * ext2_fs.h: Add new field in superblock for default mount options.
820 2002-10-13 Theodore Ts'o <tytso@mit.edu>
822 * ext2fs.h: Add #include of header files necessary for ext2fs.h to
825 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
827 * rw_bitmaps.c (ext2fs_write_block_bitmap,
828 ext2fs_read_block_bitmap): Don't set the CHANGED bit just
829 because the bitmap is getting written to disk. Make
830 ext2fs_swap_bitmap be a static function, since it's not
831 intended to be exported.
833 * swapfs.c (ext2fs_swap_super): Byte-swap the hash seed
835 2001-09-24 Theodore Tso <tytso@mit.edu>
837 * Release of E2fsprogs 1.29
839 2001-08-31 Theodore Tso <tytso@thunk.org>
841 * Release of E2fsprogs 1.28
843 2002-08-31 Theodore Ts'o <tytso@valinux.com>
845 * dblist.c (ext2fs_dblist_sort): New function which allows the
846 caller to pass in a special sort comparison function.
848 2002-08-20 Theodore Ts'o <tytso@mit.edu>
850 * valid_blk.c (ext2fs_inode_has_valid_blocks): Fix bug which
851 failed to accurately characterize non-standard slow
852 symlinks. (Which don't appear in practice on real-life
853 systems, fortunately.)
855 2002-08-17 Theodore Ts'o <tytso@mit.edu>
857 * Makefile.in: Remove inode_io.o from the standard object files,
858 and only build it if debugfs is enabled (it requires
859 fileio.o, which is only built if --disable-debugfs isn't
860 specified to configure).
862 * dirhash.c (ext2fs_dirhash): Change the MD4 hash in a backwards
863 incompatible way so that it is no longer
864 endian-dependent. Add the TEA hash. Allow the seed
865 parameter to be optional.
867 * ext2_fs.h: Remove the HALF_MD4_SEED and HALF_MD4_64 hashes.
868 These features are all now in the HALF_MD4 hash. Add
869 definition for EXT2_HASH_TEA.
871 * ext2fs.h (ext2fs_dirhash): Change function prototype so it takes
872 a pointer instead of an array.
874 2002-08-16 Theodore Ts'o <tytso@mit.edu>
876 * ext2_err.et.in (EXT2_ET_BAD_EA_BLOCK_NUM): New error code
878 * ext2fs.h (ext2fs_inode_data_blocks): New function which returns
879 the number of data blocks used by an inode exclusive of
882 * ext_attr.c (ext2fs_adjust_ea_refcount): New function which
883 adjusts the reference count in an extended attribute block.
885 * valid_blk.c (ext2fs_inode_has_valid_blocks): Add code to
886 correctly deal with extended attribute blocks in symbolic
889 2002-08-13 <tytso@snap.thunk.org>
891 * Makefile.in: Move dupfs.o and test_io.o from the
892 needed-by-debugfs object list to the needed-by-resizer
893 object list. Fixes compile problem if the system is built
894 with only --disable-debugfs.
896 2002-07-29 Theodore Ts'o <tytso@mit.edu>
898 * link.c (ext2fs_link): When adding a new link to a directory,
901 2002-07-23 Theodore Ts'o <tytso@mit.edu>
903 * dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
904 calculations for names > 32 characters to be completely
905 bogus. Changed MD4 calculation to match what is currently
906 being used in the CVS gkernel tree.
908 2002-07-19 Theodore Ts'o <tytso@mit.edu>
910 * ext2_fs.h: Add s_hash_seed and s_def_hash_version to the
911 superblock definition.
913 * badblocks.c, freefs.c, ext2fs.h: Use the badblocks functions to
914 create a set of u32_list functions.
916 * dirhash.c (halfMD4Transform): Shift the hash by one bit,
917 since that's required by the directory indexing code.
919 2002-07-14 Theodore Ts'o <tytso@mit.edu>
921 * ext2fs.h, read_bb_file.c: Change private to priv_data, to avoid
922 using a C++ reserved word.
924 * unix_io.c (unix_open): Only attempt the setrlimit workaround if
925 the kernel version is 2.4.10 -- 2.4.17, since otherwise an
926 old version of glibc (built against 2.2 headers) will
927 interact badly with the workaround to actually cause more
928 problems. I hate it when the glibc folks think they're
929 being smarter than the kernel....
931 2002-06-28 Andreas Dilger <adilger@clusterfs.com>
933 * ext2_fs.h: Add superblock field for reserved group descriptors.
935 2002-06-28 Theodore Ts'o <tytso@mit.edu>
937 * bitops.h: Add #define's for ext2fs_{l,b}e{32,16}_to_cpu and
938 ext2fs_cpu_to_{l,b}e{32,16}
940 2002-06-27 Theodore Ts'o <tytso@mit.edu>
942 * ismounted.c (check_mntent): In AIX 4.3, MOUNTED isn't defined.
943 Add appropriate fallbacks in this case.
945 2002-06-26 Theodore Ts'o <tytso@mit.edu>
947 * dirhash.c (ext2fs_dirhash): Change function signature to support
948 a hash seed, and to return the minor hash (for 64-bit hash
949 support). Add support for the half MD4, half MD4 with
950 seed, and half MD4 with seed and 64 bits.
952 2002-06-15 Theodore Ts'o <tytso@mit.edu>
954 * ext2_fs.h (EXT2_DIRSYNC_FL): Add new file.
956 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
958 * ext2_fs.h: Add macros for maximum block/inode counts:
959 EXT2_INODES_PER_BLOCK, EXT2_MAX_BLOCKS_PER_GROUP,
960 and EXT2_MAX_INODES_PER_GROUP.
962 * openfs.c (ext2fs_open): Check that the number of blocks in a group
963 is less than 2^16, otherwise we need an INCOMPAT flag (not
964 in existence yet, if ever) to open such a filesystem.
966 * initialize.c (ext2fs_initialize): Limit the number of blocks and
967 inodes in a group to less than 2^16.
969 2002-06-09 Andreas Dilger <adilger@clusterfs.com>
971 * ext2_fs.h: Further minor cleanups of the header. Consolidate
972 some checks for __KERNEL__ into one place.
974 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
976 * ext2_fs.h: Remove macros accessing u.ext2_sb field and use
977 the EXT2_SB() macro instead. Remove kernel function
978 prototypes also. This matches the 2.5 kernel, and
979 is also cleaner for other reasons. Whitespace cleanup.
981 2002-05-21 Theodore Ts'o <tytso@mit.edu>
983 * ext2_ext_attr.h: Update to V2 version of the Bestbits format.
985 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
987 * ext2_fs.h: Change limits to support filesystems with 8k blocks.
989 * initialize.c (ext2fs_initialize): Remove assumption that
990 blocksizes are always <= 4k.
992 2002-05-11 Theodore Ts'o <tytso@mit.edu>
994 * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail
995 silently if inode pointer is NULL (and ext2fs_bmap is
996 expected to read the inode itself).
998 2002-04-27 Theodore Ts'o <tytso@mit.edu>
1000 * ismounted.c (check_mntent_file, is_swap_device): Verify that the
1001 file we are checking is a block device file before looking
1002 at st_rdev, since it's not valid for normal files.
1003 (is_swap_device): Move so that it is outside the
1004 HAVE_MNTENT_H, so that it is always built.
1006 2002-03-11 Theodore Tso <tytso@mit.edu>
1008 * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New
1009 functions which take an extra flags argument. The flag
1010 EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len
1011 field is byte swampped on big-endian machines, since in
1012 the V2 structure, name_len is a char field which is
1013 doesn't need to be byte swapped --- except if an
1014 old-style kernel had byte-swapped the name_len field
1015 as part of the V1 structure.
1017 * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code
1019 * dirhash.c (ext2fs_dirhash): New function which calculates the
1020 hash for a filename in an indexed directory.
1022 2002-03-08 Theodore Tso <tytso@mit.edu>
1024 * Release of E2fsprogs 1.27
1026 2002-03-07 Theodore Tso <tytso@mit.edu>
1028 * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype.
1030 * bmap.c, fileio.c, inode_io.c, tst_badblocks.c,
1031 tst_byteswap.c: Fix gcc -Wall complaints
1033 * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs.
1034 (From Philipp Thomas <pthomas@suse.de>)
1036 2002-02-25 Theodore Tso <tytso@mit.edu>
1038 * ext2_fs.h: Add structure definitions for the directory indexing
1041 2002-02-23 Theodore Tso <tytso@mit.edu>
1043 * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that
1044 it doesn't break things on mis32, sparc32, and alpha
1047 2002-02-21 Theodore Tso <tytso@mit.edu>
1049 * ismounted.c (is_swap_device): Fix file descriptor/memory leak;
1050 we were missing an fclose().
1052 2002-02-20 Theodore Tso <tytso@mit.edu>
1054 * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io
1055 abstraction interface which exports an ext2 inode.
1057 * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush
1058 as a public interface. Change void * to const void * in
1059 ext2fs_file_write's interface.
1061 * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded
1062 conditional; save a few bytes.
1064 2002-02-12 Theodore Tso <tytso@mit.edu>
1066 * Makefile.in (tst_badblocks): Add some extra .o files when
1067 linking the debugging program tst_badblocks which are
1068 needed if we aren't compiling with inline functions enable.
1070 * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers,
1071 define away __inline__ since it may not be supported.
1073 * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a
1074 stripped down jbd_debug that doesn't use variadic
1075 arguments. This will cause warnings under AIX, but things
1078 2002-02-03 Theodore Tso <tytso@thunk.org>
1080 * Release of E2fsprogs 1.26
1082 2002-02-03 Theodore Tso <tytso@mit.edu>
1084 * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2
1085 so that the number of directories in use is adjusted
1088 * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function
1089 which optionally will modify the number of directories
1092 2002-01-03 Theodore Tso <tytso@mit.edu>
1094 * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block):
1095 Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
1096 which will return deleted directory entries.
1097 ext2fs_dir_iterate2 takes a new callback function which
1098 is identical with the one used by
1099 ext2fs_dblist_dir_iterate(). If the directory entry is
1100 deleted, the callback function will be called with the
1101 entry paraemter set to DIRENT_DELETED_FILE.
1103 * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
1104 ext2fs_block_alloc_stats): New functions which update
1105 block/inode allocation statistics in the bitmaps, block
1106 group descriptors, and superblock.
1108 * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
1109 expanddir.c (expand_dir_proc), bb_inode.c
1110 (clear_bad_block_proc, set_bad_block_proc,
1111 ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
1112 Update to use new block/inode allocation statistics.
1114 2001-12-24 Theodore Tso <tytso@mit.edu>
1116 * ismounted.c (is_swap_device): New function used by
1117 ext2fs_check_if_mounted and ext2fs_check_mount_point which
1118 determines whether or not the specified device is a swap
1119 device by using /proc/swaps. More bulletproofing for
1120 idiotic/careless system administrators!
1122 * ext2fs.h, openfs.c (ext2fs_open), initialize.c
1123 (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new
1124 field to struct_ext2_filsys, umask. This field is
1125 initialize to 022, and affects ext2fs_mkdir in the obvious
1126 way. (In the future umask should also affect new file
1127 creation routines, but the fileio functions don't
1128 currently support this yes.)
1130 * ismounted.c (check_mntent_file): Stat all of the entries in
1131 /etc/mtab and/or /proc/mounts in order to catch dim-witted
1132 system administrators who might have created alias
1135 2001-12-23 Theodore Tso <tytso@mit.edu>
1137 * Makefile.in, jfs_user.h: Move linux/jbd.h to
1138 ext2fs/kernel-jbd.h, to avoid using the system header
1139 file version of hbd.h when using diet glibc (since it
1140 forcibly adds /usr/include to the beginning of the
1141 include search path.)
1143 * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from
1144 include/linux directory.
1146 2001-12-16 Theodore Tso <tytso@mit.edu>
1148 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap),
1149 ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr),
1150 fileio.c (ext2fs_file_write): Fix gcc -Wall nits
1152 * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to
1155 2001-12-03 Theodore Tso <tytso@mit.edu>
1157 * unix_io.c (unix_open): Make sure the ulimit workaround works
1158 regardless of the version of glibc which is used to
1161 2001-11-26 Theodore Tso <tytso@mit.edu>
1163 * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by
1164 trying to unset the filesize limit if at all possible,
1165 if a block device is getting opened. (The filesize limit
1166 shouldn't be applied against writes to a block device, but
1167 starting in 2.4.10, the kernel is doing this.)
1169 2001-11-05 Theodore Tso <tytso@mit.edu>
1171 * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal
1172 file on adding a journal to an already-mounted filesystem,
1173 try to clear the ext2 file attributes on an already
1174 existing .journal file so that we don't fail if on a
1175 partially added journal to the filesystem.
1177 * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL,
1178 which signals that a particular inode should not have the
1179 last bits of data (the "tail") be merged with another
1180 file. This is necessary to keep LILO happy.
1182 2001-09-20 Theodore Tso <tytso@thunk.org>
1184 * Release of E2fsprogs 1.25
1186 2001-09-16 Theodore Tso <tytso@mit.edu>
1188 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
1189 which was breaking the build on the Hurd. (Addresses
1190 Debian bug #112414).
1192 2001-09-13 Theodore Ts'o <tytso@mit.edu>
1194 * ismounted.c (check_mntent_file): We now validate the entry in
1195 /etc/mtab to make sure the filesystem is really mounted,
1196 since some broken distributions (read: Slackware) have
1197 buggy boot scripts that don't initialize /etc/mtab before
1198 checking non-root filesystems. (Slackware also doesn't
1199 check the root filesystem separately, and reboot if the
1200 root filesystem had changes applied to it, which is
1201 dangerous and broken.)
1203 2001-09-02 Theodore Tso <tytso@thunk.org>
1205 * Release of E2fsprogs 1.24a
1207 2001-08-30 Theodore Tso <tytso@thunk.org>
1209 * Release of E2fsprogs 1.24
1211 2001-08-30 Theodore Tso <tytso@valinux.com>
1213 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
1214 changes, since the ioctl number has been reused by another
1217 2001-08-15 Theodore Tso <tytso@valinux.com>
1219 * Release of E2fsprogs 1.23
1221 2001-08-05 Theodore Tso <tytso@valinux.com>
1223 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
1224 version of the bitmap test routines to speed up these
1225 routines. (At some point I may want to make these
1226 routines use the find_first_bit functions, but that will
1227 add a lot of complexity since it means that these
1228 functions will have to break the bitmap abstraction
1229 boundary. It's not clear it's worth it.)
1231 * mkjournal.c (mkjournal_proc): Remember the last block allocated
1232 to speed up ext2fs_new_block().
1234 2001-07-29 Theodore Tso <tytso@valinux.com>
1236 * finddev.c (scan_dir): Fix memory leak; we weren't calling
1237 closedir() when exiting the function in all cases.
1239 2001-07-27 Theodore Tso <tytso@valinux.com>
1241 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
1242 block usable in the journal for external journals to be 2
1243 or 3, depending on the blocksize, so that the existing
1244 kernel code does the right thing.
1246 * getsize.c (ext2fs_get_device_size): Add support for the
1247 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
1248 from Ben LaHaise, but it's likely this interface won't
1251 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1252 when writing the journal superblock, too. (Oops! Needed
1253 to make 1k filesystems with external journal to work.)
1255 2001-07-26 Theodore Tso <tytso@valinux.com>
1257 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
1258 to find the journal superblock if the blocksize is 1024.
1260 2001-07-21 Theodore Tso <tytso@valinux.com>
1262 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
1264 2001-07-20 Theodore Tso <tytso@valinux.com>
1266 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
1267 attribute block, set the filesystem changed bit.
1269 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1270 Comment out these functions since we're not using them.
1272 2001-07-10 Theodore Tso <tytso@valinux.com>
1274 * closefs.c (write_primary_superblock): After writing changes to
1275 the primary superblock, update the original superblock
1276 copy so we don't have to re-write those changes in the
1278 (ext2fs_flush): Clear the superblock dirty flag after
1279 we've flushed out changes to disk.
1281 2001-07-07 Theodore Tso <tytso@valinux.com>
1283 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
1284 to avoid register conflicts when compiling in PIC mode.
1286 2001-07-04 Theodore Tso <tytso@valinux.com>
1288 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
1289 Add new functions (C and in i386 assembler) which quickly
1290 find bits set in a bitmask.
1292 2001-06-23 Theodore Tso <tytso@valinux.com>
1294 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
1295 ext2_ext_attr.h and ext_attr.c for extended attributes
1298 * Release of E2fsprogs 1.22
1300 2001-06-22 Theodore Tso <tytso@valinux.com>
1302 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
1303 descriptor so that adding a journal to a mounted
1304 filesystem doesn't die. (Fixes a bug accidentally
1305 introduced in e2fsprogs 1.21.)
1307 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
1308 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
1309 fchflags without defining UF_NODUMP. (Addresses Debian
1312 * flushb.c: Use platform independent method of defining the
1313 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
1314 since on newer glibc's BLKFLSBUF is defined there.
1316 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
1317 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
1318 to support byte swapping even if we don't support the
1319 conversion functions. (Fixes Debian bug #101686).
1321 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
1322 since the byte-swapping code all assumes the
1323 ext2_dir_entry structure. (It's a question of whether or
1324 not name_len should be byte-swapped or not, and whether
1325 it's a 16 bit or 8 bit field.)
1327 2001-06-15 Theodore Tso <tytso@valinux.com>
1329 * Release of E2fsprogs 1.21
1331 2001-06-15 Theodore Tso <tytso@valinux.com>
1333 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
1334 file which is generated and is therefore found in the
1335 build directory, not source directory.
1337 * ismounted.c (check_mntent_file): Use a test file in / to check
1338 to see if the root filesystem is mounted read-only. This
1339 protects against the case where /etc might not be on /, as
1340 well as the case where /etc/mtab doesn't exist. (Both are
1341 should-never happen scenarios, but you never know...)
1343 2001-06-14 Theodore Tso <tytso@valinux.com>
1345 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
1346 Remove unneeded #pragma argsused, since the arguments are
1349 2001-06-13 Theodore Tso <tytso@valinux.com>
1351 * ext2_types.h.in: If linux/types.h has been defined, then don't
1352 try to redefine the typedefs.
1354 * Makefile.in (HFILES): Add ext2_types.h to the list of files
1355 which should be installed.
1357 * ismounted.c (check_mntent_file): Work around GNU hurd brain
1358 damage. Addresses Debian bug #100304.
1360 * Makefile.in: Limit some .o files from being included into the
1361 library if --disable-debugfs, --disable-swapfs,
1362 --disable-imager, or --disable-resizer are used.
1364 2001-06-12 Theodore Tso <tytso@valinux.com>
1366 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
1367 function, and use the ext2fs_badblocks_* functions
1370 2001-06-11 Theodore Tso <tytso@valinux.com>
1372 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
1373 ext2fs_mark_generic_bitmap and
1374 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
1375 functions. (This saves space and doesn't significantly
1376 change the speed of e2fsck on a P-III.)
1378 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
1379 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
1380 include the byte-swapping logic if ENABLE_SWAPFS is turned
1381 on or if we're on a big-endian machine.
1383 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
1384 set EXT2_FLAG_SWAP_BYTES, instead of using
1387 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
1388 autoconf to determine whether or not return
1389 EXT2_FLAG_SWAP_BYTES.
1391 2001-06-10 Theodore Tso <tytso@valinux.com>
1393 * Makefile.in: Remove the dependence on the libe2p library.
1395 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
1396 with direct usage of the ioctl/fchflags so that we don't
1397 have to depend on the libe2p library.
1399 2001-06-08 Theodore Tso <tytso@valinux.com>
1401 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
1402 when trying to find a 32-bit wide type.
1404 * icount.c (insert_icount_el): Fix the code used to estimate the
1405 size of the new icount array to be more intelligent, to
1406 avoid reallocating the array too many times. Thanks to
1407 Enrique Perez-Terron for pointing this out.
1409 2001-06-02 Theodore Tso <tytso@valinux.com>
1411 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
1412 for a symlink to determine whether it is a fast symlink.
1414 2001-06-01 Theodore Tso <tytso@valinux.com>
1416 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
1417 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
1419 2001-05-25 Theodore Tso <tytso@valinux.com>
1421 * Release of E2fsprogs 1.20
1423 2001-05-25 Theodore Tso <tytso@valinux.com>
1425 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
1426 some to clean up Andreas's patches. Use strncpy instead
1427 of strcpy to save the root's mountpoint. Clean up #ifdef
1428 structure. Remove uneeded variable in testing/debug driver.
1430 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
1432 * ismounted.c: Add check for root device which doesn't depend on
1433 /etc/fstab or /proc/mounts to be correct. Don't call
1434 endmntent() before we are done with mnt struct.
1436 2001-05-23 Theodore Tso <tytso@valinux.com>
1438 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
1441 2001-05-21 Theodore Tso <tytso@valinux.com>
1443 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
1444 make room for pre-existing usage of
1445 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
1446 the same codepoint as EXT2_BTREE_FL.
1448 2001-05-20 Theodore Tso <tytso@valinux.com>
1450 * ext2fs.h: #include <> instead of "" for ext2fs and et header
1451 files, since they will be installed in /usr/include
1453 2001-05-14 Theodore Tso <tytso@valinux.com>
1455 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
1456 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
1457 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,

1466 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
1467 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
1468 Adjust all files in this directroy to include this file.
1470 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
1473 2001-05-05 Theodore Tso <tytso@valinux.com>
1475 * fileio.c (ext2fs_file_read): Factored out common code and
1476 cleaned up function. Fixed a bug where if there was an
1477 error reading from the disk, the number of bytes read
1478 wasn't reliably set. (Fixes Debian bug #79163)
1479 (ext2fs_file_write): Factored out common code and made
1480 function more efficient; if writing a full block, don't
1481 bother to do a read-modify-write cycle.
1483 2001-05-04 Theodore Tso <tytso@valinux.com>
1485 * dirblock.c (ext2fs_read_dir_block): Check for an directory
1486 record length which isn't a multiple four, and treat that
1487 as an invalid. Scan the directory and return an error
1488 (EXT2_ET_DIR_CORRUPTED) if the directory records are
1490 (ext2fs_write_dir_block): If while byte-swapping the
1491 directory block, if there's an error, abort and return
1492 EXT2_ET_DIR_CORRUPTED.
1494 2001-05-02 Theodore Tso <tytso@valinux.com>
1496 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
1497 image_header field in the ext2_filsys structure
1499 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
1500 * inode.c (ext2fs_read_inode):
1501 * rw_bitmaps.c (read_bitmaps):
1502 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
1504 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
1505 sure the full bitmap is saved.
1507 2001-05-01 Theodore Tso <tytso@valinux.com>
1509 * e2image.h (struct ext2_image_hdr): Add space for the device name
1510 in the image header.
1512 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
1513 make sure the rec_len is a multiple of 4, to prevent
1514 bus-errors on architectures which care about mis-aligned
1517 2001-04-25 Theodore Tso <tytso@valinux.com>
1519 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
1520 query the device sizes using the BLKGETSIZE ioctl.
1522 2001-04-16 Theodore Tso <tytso@valinux.com>
1524 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
1525 before checking /etc/mtab. The EXT2_MF_READONLY flag is
1526 now set from the /etc/mtab options field for all
1527 filesystems, not just the root filesystem. Add debugging
1528 code to make it easier to test ext2fs_check_if_mounted().
1530 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
1531 check; return an error if there's an attempt to create a
1532 journal less than 1024 filesystem blocks.
1534 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
1535 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
1537 2001-02-20 Theodore Tso <tytso@valinux.com>
1539 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
1542 * tst_byteswap.c: New function to test the byteswap functions.
1543 Add to regression test suite.
1545 2001-02-08 Theodore Tso <tytso@valinux.com>
1547 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
1549 2001-02-07 Theodore Tso <tytso@valinux.com>
1551 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
1552 of s_first for external devices to always be 1, since
1553 jsb->s_first is always relative to the start of the
1554 journal superblock. Use htonl(1) when setting s_nr_users.
1556 2001-01-17 Theodore Ts'o <tytso@valinux.com>
1558 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
1559 device number of the filesystem (instead of the journal)
1560 was being dropped into s_journal_dev.
1562 2001-01-15 Theodore Ts'o <tytso@valinux.com>
1564 * initialize.c (ext2fs_initialize): Add support for initializing
1565 the ext2 superblock for external journal devices. This
1566 basically means we don't bother to allocate any block
1569 * openfs.c (ext2fs_open): Only open external journal devices if
1570 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
1571 ext2fs_open. When opening such devices, don't try to read
1572 the block group descriptors, since they're not there.
1574 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
1576 * mkjournal.c: Export a new function,
1577 ext2fs_create_journal_superblock(), which allocates and
1578 returns a buffer containing a journal superblock. This is
1579 needed by mke2fs to create an external journal. Rewrote
1580 ext2fs_add_journal_device() so that it no longer creates
1581 the external journal, but rather adds a filesystem to an
1582 existing external journal. It handles all of the UUID
1585 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
1586 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
1587 Changed function prototype for ext2fs_add_journal_device().
1589 2001-01-14 Theodore Ts'o <tytso@valinux.com>
1591 * closefs.c (ext2fs_flush): Don't write out anything beyond the
1592 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
1595 2001-01-12 Theodore Ts'o <tytso@valinux.com>
1597 * imager.c: Fix gcc -Wall complaints and a series of bugs where
1598 retval wasn't set correctly. (Thanks to Andreas Dilger
1599 for pointing this out.)
1601 2001-01-11 <tytso@snap.thunk.org>
1603 * flushb.c (ext2fs_sync_device): New function which centralizes
1604 all of the places which might try to use the BLKFLSBUF
1605 or FDFLUSH ioctls (and usually failing to define them
1606 since the system header files don't usually do this for
1607 us, and we're trying to avoid usage of kernel include
1610 2001-01-10 <tytso@snap.thunk.org>
1612 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
1613 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
1614 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
1615 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
1616 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
1617 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
1618 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
1619 ext2_ino_t, to protect applications that attempt to
1620 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
1621 changes ino_t(!?). So we use ext2_ino_t to avoid an
1622 unexpected ABI change.
1624 2001-01-05 <tytso@snap.thunk.org>
1626 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
1627 we may overrun allocated memory in case of a corrupted
1628 filesystem (or an e2fsck test case :-) when byte-swapping
1629 the directory block.
1631 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
1633 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
1634 complaints including a missing return 0 at the end of
1635 ext2fs_add_journal_device.
1637 2001-01-03 <tytso@snap.thunk.org>
1639 * Makefile.in: Link in libe2p when creating libext2fs as a shared
1640 library, since mkjournal.c now references fsetflags().
1642 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
1643 Dilger's changes (with fixups) to allow on-line creation
1646 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
1647 EXT2_FLAG_SUPER_ONLY, which the close routines to only
1648 update the superblock, and not the group descriptors.
1650 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
1652 * ismounted.c: add ext2fs_check_mount_point() function, which will
1653 optionally return the mount point of a device if mounted
1655 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
1657 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
1658 ext2fs_add_journal_inode()
1660 2001-01-01 <tytso@snap.thunk.org>
1662 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
1663 source (but not binary) compatibility of some users of the
1664 ext2 library. They should just simply do a global search
1665 and replace of struct ext2fs_sb with struct
1666 ext2_super_block, and use their own private copy of
1667 ext2_fs.h if they aren't already.
1669 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
1670 Replace use of ext2fs_sb with ext2_super_block.
1672 2000-12-31 <tytso@snap.thunk.org>
1674 * ext2fs.h: Cleaned up header file by removing definitions of
1675 feature flags that might not have been defined in older
1676 ext2 header files. Now that we're using our own
1677 include/linux/ext2fs.h header file, this can never happen.
1679 * jfs_dat.h: Removed old header file which is no longer needed.
1681 2000-12-13 Theodore Ts'o <tytso@valinux.com>
1683 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
1684 by Andreas Dilger to update the filesystem revision to
1687 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
1690 2000-12-09 <tytso@snap.thunk.org>
1692 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
1693 ext2fs_add_journal_device): Add a new argument to the APIs
1694 of these function, which is a flags word. This is used to
1695 allow the creation of a V1 superblock for those folks who
1696 are using ext3 0.3b in production. Note, the user-land
1697 interface for getting at this flag won't be documented, as
1698 the V1 superblock is deprecated.
1700 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
1701 which creates a V2 superblock instead of a V1 superblock.
1703 2000-11-21 <tytso@snap.thunk.org>
1705 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
1706 out by Andreas Dilger.
1708 2000-11-05 <tytso@snap.thunk.org>
1710 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
1711 ext2_fs.h, Makefile.in: New file that has routines that
1712 save ext2fs metadata to a file.
1714 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
1716 * e2image.h: New file which defines the file format for the ext2
1717 image file. (Saved copy of ext2 metadata to a file as a
1718 saving throw against worst-case damage.)
1720 2000-11-01 <tytso@snap.thunk.org>
1722 * inode.c (ext2fs_flush_icache): Add new function
1723 ext2fs_flush_icache() which flushes the internal inode
1724 cache. Applications which modify the inode table blocks
1725 directly must call this function.
1727 2000-10-26 <tytso@snap.thunk.org>
1729 * mkjournal.c: Add #include of netinet/in.h, since Solaris
1730 requires it for ntohl().
1732 * ext2_io.h (io_channel_write_byte): Add new interface to allow
1733 callers to write specific byte ranges. This is an
1734 optional interface, which not all IO channels may
1737 * unix_io.c (unix_write_byte):
1738 * test_io.c (test_write_byte): Add implementation of the
1739 write_byte function.
1741 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
1742 function which writes the primary superblock. If the IO
1743 channel supports writing raw bytes directly, only fields
1744 which were modified are written to the disk. This makes
1745 it safe(r) to use utilities like tune2fs on a mounted
1748 * freefs.c (ext2fs_free): Free the original superblock if it is
1751 * openfs.c (ext2fs_open): Store a copy of the original superblock
1754 * ext2fs.h: Add a field to store the original superblock in the
1755 ext2 context structure.
1757 2000-10-24 <tytso@snap.thunk.org>
1759 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
1760 don't need to use llseek).
1762 2000-10-24 <tytso@valinux.com>
1764 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
1765 creating an ext3 journal on a filesystem.
1767 2000-08-21 <tytso@valinux.com>
1769 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
1771 2000-08-22 <tytso@valinux.com>
1773 * unix_io.c: Make massive changes to support a multiple block
1774 writethrough cacheing.
1776 * ext2_io.h: Added flags field to the io_channel structure.
1778 2000-08-19 <tytso@valinux.com>
1780 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
1781 provides the function ext2fs_find_block_device(). This
1782 function returns the pathname to a block device, given its
1785 2000-07-13 <tytso@valinux.com>
1787 * Release of E2fsprogs 1.19
1789 2000-07-07 Theodore Ts'o <tytso@valinux.com>
1791 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
1792 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
1793 list of filesystem flags supported by the library.
1795 2000-07-04 Theodore Ts'o <tytso@valinux.com>
1797 * ext2fs.h: Update to include latest journalling additions to the
1800 * dll/jump.funcs: Add new jumptable entries for
1801 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1802 ext2fs_badblocks_equal.
1804 * tst_badblocks.c: Update test program to test
1805 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
1807 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
1808 writes out bad blocks list to a file.
1810 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
1811 changes the callback function to take two additional
1812 arguments; a private blind pointer supplied by the caller,
1813 and pointer to a char * containing a pointer to the
1816 * badblocks.c (ext2fs_badblocks_equal): Add new function which
1817 returns true if two badblocks list are equal.
1819 * Makefile.in: Remove explicit link of -lc in the shared library.
1820 (It shouldn't be necessary, and is harmful in some cases).
1822 2000-06-10 Theodore Ts'o <tytso@valinux.com>
1824 * getsize.c (main): Add debugging code under #ifdef DEBUG
1826 2000-05-27 Theodore Ts'o <tytso@valinux.com>
1828 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
1829 earlier, so that if there's an error reading it, we can
1830 more cleanly back out of the operation.
1832 2000-05-25 <tytso@snap.thunk.org>
1834 * getsize.c (ext2fs_get_device_size): Use open64() instead of
1835 open() if it exists. Under linux, manually define the
1836 ioctl for BLKGETSIZE if it isn't already defined and it's
1839 * unix_io.c (unix_open): Use open64() instead of open() if it
1842 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
1843 available (and prototypes are defined) use it in
1844 preference to llseek.
1846 * Makefile: Add hack dependency rule so that parallel makes work
1849 2000-05-18 Theodore Ts'o <tytso@valinux.com>
1851 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
1853 2000-04-03 Theodore Ts'o <tytso@valinux.com>
1855 * block.c: Readibility tweak in conditionals involving
1858 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
1859 how to define __s64 and __u64. Turn off "compression is
1860 experimental" warning if the cpp macro
1861 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
1863 2000-02-11 <tytso@snap.thunk.org>
1865 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
1866 Conditionally include Compression as a supported type if
1867 ENABLE_COMPRESSION (via --enable-compression) is turned on.
1869 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
1871 2000-02-08 <tytso@snap.thunk.org>
1873 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
1874 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1875 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
1876 Change to return the previous state of the bit that is
1877 being marked or unmarked. For speed optimization.
1879 2000-02-02 Theodore Ts'o <tytso@valinux.com>
1881 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
1883 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
1884 needed any more; we know it will always be i_generation.
1885 Add support for swapping the high bits of the uid and gid.
1887 1999-11-19 <tytso@valinux.com>
1889 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
1890 counts if the link was successful. Patch suggested by
1893 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
1894 the source directory.
1896 1999-11-10 <tytso@valinux.com>
1898 * Release of E2fsprogs 1.18
1900 1999-11-08 <tytso@valinux.com>
1902 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
1903 since ext2fs_badblocks_list_free was moved to freefs.c.
1905 * tst_badblocks.c: Use the newer badblocks API names. Add
1906 duplicate blocks to the test inputs to test dealing with
1907 adding blocks which are already in the badblocks list.
1909 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
1910 of the list, use a shortcut O(1) operations instead of an
1911 O(n) operation. (Idea suggested by David Beattie.)
1913 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
1914 of badblocks_list_free(), to save a procedure call.
1916 1999-10-26 <tytso@valinux.com>
1918 * Release of E2fsprogs 1.17
1920 1999-10-26 <tytso@valinux.com>
1922 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
1923 seem to handle ~0UL the same way as they used to.
1925 1999-10-25 <tytso@valinux.com>
1927 * nt_io.c (_OpenNtName): Open the device using
1928 FILE_SYNCHRONOUS_IO_NONALERT instead of
1929 FILE_SYNCHRONOUS_IO_ALERT

1940 1999-10-22 <tytso@valinux.com>
1942 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
1944 * link.c (ext2fs_link): This call now uses the low three bits of
1945 the flags parameter to pass the directory filetype
1946 information; it will set the directory entry FILETYPE
1947 information if the filesystem supports it.
1949 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
1950 option is set, then create the '.' and '..' entries with
1951 the filetype set to EXT2_FT_DIR.
1953 1999-09-24 <tytso@valinux.com>
1955 * nt_io.c: New file which supports I/O under Windows NT.
1957 1999-09-07 <tytso@valinux.com>
1959 * ext2fs.h: Add new fields for journalling and define new
1960 feature bits used by newer filesystems: IMAGIC_INODES,
1961 HAS_JOURNAL, RECOVER.
1963 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
1964 we update the inode block count and size files so that the
1965 block count field is updated correctly when we create an
1968 1999-07-18 Theodore Ts'o <tytso@valinux.com>
1970 * Release of E2fsprogs 1.15
1972 1999-06-23 <tytso@valinux.com>
1974 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
1975 kernels that use i_generation instead of i_version. Patch
1976 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1978 1999-06-21 <tytso@valinux.com>
1980 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
1981 directory entry before calling the callback function.
1982 This should prevent some core dumps of insufficiently
1983 paranoid callback functions.
1985 1999-05-29 <tytso@rsts-11.mit.edu>
1987 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
1989 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
1990 that we don't handle writing yet (we do). Fixed bug where
1991 we weren't allocating a big enough buffer for ext2_bmap.
1993 1999-05-03 <tytso@rsts-11.mit.edu>
1995 * openfs.c (ext2fs_open): Check to make sure that the number of
1996 blocks per group is not zero --- if so, it must be a bad
1999 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2001 * Release of E2fsprogs 1.14
2003 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
2005 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
2006 the inode number is zero; if it's zero, return
2007 EXT2_ET_BAD_INODE_NUM.
2009 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2011 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
2012 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2

2017 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
2018 non-Linux case to use EINVAL by default, unless it isn't
2019 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
2022 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
2024 * Release of E2fsprogs 1.13
2026 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
2028 * Makefile.in: Updated dependencies.
2030 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
2032 * initialize.c (ext2fs_initialize): Make sure that we allocate
2033 enough inodes so that we can make a valid filesystem.
2035 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
2037 * rw_bitmaps.c: Fixed signed/unsigned warnings.
2039 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
2040 function declaration.
2042 * dblist.c (make_dblist): Add safety check in case the dblist
2043 pointer passed in is null (in which case, assign it to
2044 fs->dblist). Fixed some signed/unsigned warnings.
2046 * bmap.c: Make addr_per_block be of type blk_t to avoid
2047 signed/unsigned warnings.
2049 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
2050 function declaration.
2052 * get_pathname.c (get_pathname_proc): Use return value from
2053 ext2fs_get_mem, instead of checking if &gp->name is
2056 * dir_iterate.c (ext2fs_process_dir_block):
2057 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
2058 from the function declaration.
2060 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
2061 return the error directly instead of jumping to the
2062 cleanup routine, since we don't need to do any cleanup.
2064 * alloc_table.c (ext2fs_allocate_group_table): Make this
2065 function take a dgrp_t for its group argument.
2067 * ext2fs.h: Make dgrp_t an __u32 type, and make
2068 fs->desc_group_count be of type dgrp_t.
2070 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
2072 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
2073 than 10 blocks when we need to expand the size of the
2076 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
2078 * Release of E2fsprogs 1.12
2080 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2082 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
2083 appropriate for all of the block group copies, so that
2084 it's clear where the beginning of the filesystem is on the
2085 disk. (For when the partition table gets scrod.)
2087 * ext2fs.h: Change the name of the feature from
2088 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
2089 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
2091 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
2093 * inode.c (get_next_blockgroup): Fix bug where if
2094 get_next_blockgroup() is called early because of a missing
2095 inode table in a block group, the current_inode counter
2096 wasn't incremented correctly.
2098 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
2100 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
2101 against a completely trashed bad block inode.
2103 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
2105 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
2106 the stride length hits a bad value, we retry the block
2107 allocation starting at the beginning of the block group.
2109 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
2110 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
2111 e2_blkcnt_t to avoid collision with LFS API.
2113 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
2115 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
2116 way that avoids overflows on disk sizes greater than 4GB.
2118 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
2120 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
2121 return type for comparison functions for qsort.
2123 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
2126 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
2128 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
2131 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
2132 evade a potential problem with glibc's header files trying
2133 to spike out linux/types.h.
2135 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
2136 include the old size of the memory, which is needed for
2137 some braindamaged memory allocation systems that don't
2140 * badblocks.c (ext2fs_badblocks_list_add):
2141 bb_inode.c (clear_bad_block_proc):
2142 dblist.c (ext2fs_add_dir_block):
2143 icount.c (insert_icount_el):
2144 irel_ma.c (ima_put):
2145 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
2146 pass the old size of the memory to be resized to
2147 ext2fs_resize_mem().
2149 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
2151 * Makefile.in: Change to use new installation directory variables
2152 convention. Fix uninstall rules to take $(DESTDIR) into
2155 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
2157 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
2158 with 32 bit longs, then we need to manually define __s64
2159 and __u64, since the current kernel header files don't
2160 define these if __STRICT_ANSI__ is defined. This is a
2161 problem if we are compiling with full GCC warnings, since
2162 we do need 64 bit support.
2164 * Makefile.in (OBJS): Remove bmove.o from files to be built,
2165 since we're not using ext2fs_move_blocks() and there
2166 is some question as to its usefulness in its current
2169 * bmap.c (block_bmap): Remove unused function.
2171 * bmove.c (process_block): Fix -Wall warning.
2173 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
2175 * block.c (ext2fs_block_iterate3): Make the ref_offset field
2176 contain the offset into the inode.i_blocks array when
2177 ref_block is zero. Since we haven't done a formal
2178 release of e2fsprogs since block_iterate2 was first
2179 introduced, I removed block_iterate2, and renamed
2180 block_iterate3 to be block_iterate2.
2182 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
2183 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
2184 use of block_iterate and block_iterate2 to
2185 block_iterate2 with the new prototype for the
2186 interator function. (using blkcnt_t forr blockcount)
2188 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
2190 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
2191 s_prealloc_blocks, s_prealloc_dir_blocks). Added
2192 conditional defines of new features COMPAT_DIR_PREALLOC,
2193 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
2194 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
2195 the library to declare that we support COMPAT_DIR_PREALLOC,
2196 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
2198 * fileio.c: Rename function ext2fs_file_llseek to be
2199 ext2fs_file_lseek, which is more accurate.
2201 * block.c: Add new function ext2fs_block_iterate3 which calls
2202 the iterator function with the blockcount argument of
2203 type blkcnt_t. This version of the function is
2204 allowed to handle large files; the other fucntions are
2207 * ext2fs.h: Add new type blkcnt_t
2209 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
2211 * block.c (ext2fs_block_iterate2): Fix bug where the block count
2212 field wasn't getting correctly incremented for sparse
2213 files when the indirect or doubly-indirect block
2214 specified in the inode was zero.
2216 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2218 * unlink.c (unlink_proc):
2219 * lookup.c (lookup_proc):
2220 * link.c (link_proc):
2221 * get_pathname.c (get_pathname_proc):
2222 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
2223 from dirent->name_len, so it can be used for other
2226 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
2227 and indicate that we have support for this incompatible
2230 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2232 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

2236 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
2237 number of directories when the block group information is
2240 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
2242 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
2243 inode table is missing so that we catch the case where the
2244 first block group is missing.
2246 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
2249 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2251 * ext2_io.h, ext2fs.h: Protect against being included multiple times.

2255 * test_io.c (test_flush): Add a debugging printf when the flush
2258 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
2259 read in, return right away.

2263 * bitops.h: Don't try to do i386 inline asm functions if the
2266 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
2267 instead of linux/types.h, and e2_bitops.h instead of
2270 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
2273 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
2275 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
2276 so that we don't need to call get_next_blockgroup() the
2277 first time around. Saves a bit of time, and prevents us
2278 from needing to assign -1 to current_group (which is an
2281 * icount.c (insert_icount_el): Cast the estimated number of inodes
2282 from a float to an ino_t.
2284 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

2294 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
2295 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
2296 defined, then assume all of the
2297 ext2-specific header files are in a flat directory.
2299 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
2300 all assignments from void * to be compatible with C++.

2321 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2323 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
2324 paranoid about validating the directory counts from the
2325 block group information.
2327 * all files: Don't include stdlib.h anymore; include it in
2328 ext2_fs.h, since that file requires stdlib.h
2330 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2332 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
2333 bitmap is loaded, and return an error if it is not.
2334 (expand_dir_proc): Only use ext2fs_write_dir_block when

2449 * io.h: Change the prototype of ext2fs_llseek() to use int's
2450 instead of unsigned int's.
2452 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
2453 to make life easer for GNU Libc 2.
2455 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
2456 filesystem has its bitmaps stored as 32-bit words with bit
2457 0 as the LSB of each word. Thus a bitmap with only bit 0
2458 set would be, as a string of bytes, 00 00 00 01 00 ... To
2459 cope with this, we byte-reverse each word of a bitmap if
2460 we have a big-endian filesystem, that is, if we are *not*
2461 byte-swapping other word-sized numbers.

2581 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
2582 ext2fs_badblocks_list_test would test the list (and exceed
2583 array boundaries) if there were no bad blocks on the bad
2584 blocks list. (Showed up when user tried: mke2fs -c -b 4096).

2643 interface io_channel_bumpcount() to bump the refcount.
2645 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2647 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode

2658 * block.c (block_iterate_ind, block_iterate_dind,
2659 block_iterate_tind): If there are holes in the indirect,
2660 doubly indirect, or triply indirect blocks, increment the
2661 block count field automatically.
2663 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2665 * Release of E2fsprogs version 1.09
2667 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2669 * version.c (ext2fs_parse_version_string): Check the passed in
2670 version string (instead of the hard-coded one).
2672 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
2673 greater filesystem size, clamp it to prevent allocating a
2674 block or inode bitmap beyond the filesystem.
2676 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
2677 overhead calculation was accidentally removed.
2679 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2681 * Release of E2fsprogs version 1.08
2683 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2685 * dblist.c (ext2fs_set_dir_block): New function which sets the
2686 block of a dblist entry, given the directory inode and
2689 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2691 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
2692 inode bitmaps at staggered locations across the block
2693 groups, to avoid concentrating the bitmaps on a small
2694 number of disks when using striped RAID arrays.
2696 * initialize.c (ext2fs_initialize): By default, choose the maximum
2697 possible number of blocks per group (based on the size of
2698 the bitmaps in the blocksize).
2700 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2702 * initialize.c (ext2fs_initialize): Add support for
2703 EXT2_COMPAT_SPARSE_SUPER feature.
2705 * closefs.c (ext2fs_bg_has_super): New function to determine
2706 whether or a particular block group should have a
2707 superblock and block group descriptor. Used for the
2708 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
2709 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
2710 or not the superblock should be written out for the block
2713 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
2714 for sparse duplicate superblocks.
2716 * version.c (ext2fs_get_library_version): New function which
2717 returns the library version.
2719 * version.c (ext2fs_parse_version_string): New function which
2720 parses a version string and returns a version number,
2721 so application programs can compare version numbers as
2724 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2726 * icount.c (ext2fs_create_icount): Change function so that it also
2727 takes a new argument which contains a "hint" icount
2728 structure. This "hint" icount allows the create function
2729 to set up the sorted list in advance. This reduces
2730 significantly the amount of data moving needed to insert
2731 these inodes into the list later.
2733 * icount.c (ext2fs_icount_validate): New function which validates
2734 that the icount structure's rep invariant.
2736 * icount.c (get_icount_el): Completely revamped implementation
2737 to subsume put_icount_el(). Put_icount_el() used to
2738 use an O(N) implementation to insert in the middle
2739 of the icount list. It now uses a O(ln N) to search
2740 for where the icount should be inserted, and then uses
2741 a memcpy to move the list down (instead of a for loop).
2743 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
2744 ext2fs_icount_increment, ext2fs_icount_decrement): Check
2745 to see if the inode is within bounds; if it isn't, return
2748 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
2749 when a bad inode number is passed to test_generic_bitmap
2750 to be EXT2FS_TEST_ERROR instead of the wrong
2751 EXT2FS_UNMARK_ERROR.
2753 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
2755 * Release of E2fsprogs version 1.07
2757 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2759 * Makefile.in (ELF_VERSION): Change version to be 2.2
2761 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2763 * alloc.c (ext2fs_get_free_blocks): Change routine to use
2764 ext2fs_fast_test_block_bitmap_range().
2766 * bitops.h (ext2fs_fast_test_block_bitmap_range,
2767 ext2fs_test_block_bitmap_range: New inline functions which
2768 test to see whether a contiguous range of blocks is
2771 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2773 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
2774 use ext2fs_badblocks_* instead of badblocks_*
2776 * bb_compat.c: New file which translates between old badblocks_*()
2777 names to ext2fs_badblocks_*()
2779 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
2780 link.c (since e2fsck doesn't use ext2fs_unlink()).
2782 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
2783 bitmap resizing routine moved from bitmaps.c, since e2fsck
2784 doesn't need to use this function.
2786 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
2787 since e2fsck only needs ext2fs_lookup.
2789 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2791 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
2792 already set; this is needed so that programs like dump
2793 which use the inode scan functions will deal with
2794 filesystems that have bad blocks in the inode table.
2796 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2798 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
2799 Moved to ext2fsP.h, since it doesn't need to be part of
2800 the public interface.
2802 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
2804 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2806 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
2807 directory block list abstraction. (Code moved from
2810 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
2811 to inode.c (since no one else should be peeking inside it!)
2813 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
2815 * openfs.c (ext2fs_open): Check the feature set in the ext2
2816 superblock, and refuse to open filesystems if they contain
2817 incompatible features. (Can be overriden with the
2820 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2822 * block.c (ext2fs_block_iterate2): Added new function
2823 ext2fs_block_iterate2 which changes the function
2824 signature of the callback function to include the
2825 referencing block and offset.
2827 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
2828 ext2fs_inode_scan_goto_blockgroup which allows an
2829 application to jump to a particular block group while
2830 doing an inode scan.
2832 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
2834 * dirblock.c: Include string.h, since we use memcpy().
2836 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2838 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
2839 a long not an int; this doesn't matter on i386 machines,
2840 but it does on Alpha's.
2842 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2844 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
2845 table pointer is NULL, then return an error indicating
2846 that the inode table is missing.
2847 (get_next_blockgroup, get_next_blocks,
2848 ext2fs_get_next_inode): Don't treat a missing inode table
2849 as permanent error. Return MISSING_INODE_TABLE, but as an
2850 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
2852 * rw_bitmaps.c (ext2fs_write_block_bitmap,
2853 ext2fs_write_inode_bitmap): If the inode or block bitmap
2854 block is zero, then don't write out the inode or block
2855 bitmap. The idea here is to avoid stomping on the
2857 (read_bitmaps): If the inode or block bitmap block is
2858 zero, then fill in that portion of the inode or block
2859 bitmap with all zeros.
2861 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
2862 blocks in inode table when the inode table size is
2863 non-standard (and can therefore span blocks).
2865 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2867 * alloc.c (ext2fs_new_block): Fix fencepost error in
2868 ext2fs_new_block; make sure we don't try to allocate the
2869 first block beyond the end of the filesystem.
2871 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2873 * inode.c (check_for_inode_bad_blocks): New function called by
2874 get_next_blocks() to avoid reading in bad blocks marked in
2875 fs->badblocks. Inodes located in bad blocks are returned
2876 by ext2fs_get_next_inode() returns the error code
2877 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
2879 * alloc_tables.c (ext2fs_allocate_tables): New function which
2880 performs the part of mke2fs's job of allocating the
2883 * test_io.c (test_close): IO manager which is used for testing
2886 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2888 * inode.c (ext2fs_get_next_inode): Separate out the function of
2889 setting up for a new block group to get_next_blockgroup().
2890 Separate out the function of reading in blocks of the
2891 inode table to get_next_blocks().
2893 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
2895 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
2896 blocks to the badblock list in sorted order. This allows
2897 badblocks_list_test to be coded using a binary search for
2900 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2902 * Release of E2fsprogs version 1.06
2904 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2906 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
2907 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
2910 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
2911 set, then only write out the master superblock.
2913 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2915 * block.c (ext2fs_block_iterate): Fixed bug which caused
2916 block_iterate to fail to handle HURD created filesystems;
2917 it tested the inode translator field before the inode was
2920 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2922 * initialize.c (ext2fs_initialize): Make sure the description for
2923 the inode bitmap is set correctly.
2925 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
2927 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2929 * Release of E2fsprogs version 1.05
2931 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2933 * initialize.c: Override the kernel's idea of default
2934 checkinterval from 0 (never) to 180 days.

2938 * namei.c (ext2fs_namei_follow): New function which follows
2939 symbolic link (if any) at the target.
2941 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2943 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
2944 for shortcut function fs->read_inode() and fs->write_inode().
2945 Added inode_cache to reduce CPU time spent in doing
2948 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
2951 * namei.c (ext2fs_follow_link): New function.
2952 (ext2fs_namei): Extended to have support for chasing
2953 symbolic links. ext2fs_namei() still returns an inode
2954 which is a symbolic link. Symbolic links are only chased
2955 while resolving the containing directory. To chase
2956 symbolic links of the final result, use
2957 ext2fs_follow_link().
2959 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2961 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
2963 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
2964 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
2966 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2968 * initialize.c (ext2fs_initialize): On systems where the byte
2969 order is not i386 compatible, set the swap_byte flag.
2971 * inode.c (inocpy_with_swap): Check to see if inode contains a
2972 fast symlink before swapping the inode block fields. This
2973 required adding a new argument to inocpy_with_swap to
2974 determine whether the mode field is in host order or not.
2976 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2978 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
2979 the sparc, if EXT2_STD_BITOPS set, use the standard
2980 i386-compatible bitmask operations, instead on the
2981 non-standard native bitmask operators.
2983 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2985 * block.c (ext2fs_block_iterate): Cause block iterator to return
2986 the HURD translator block (along with everything else).
2987 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
2988 iterator, then don't return any meta data blocks
2989 (including the HURD translator).
2991 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2993 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
2995 * uuid.c: New file, containing UUID utility functions.
2997 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
2999 * ext2fs.h: Add a definition of the "real" ext2 superblock.
3001 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3003 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
3005 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3007 * openfs.c (ext2fs_open): If the blocksize in the superblock is
3008 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
3009 that's a basic value that must be correct for the rest of
3010 the library to work.
3012 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
3015 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3017 * Release of E2fsprogs version 1.04

3021 * Release of E2fsprogs version 1.03
3023 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
3025 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
3026 Change the m68k bit numbering for bitmasks to match with
3027 the bit numbering used by all other ext2 implementations.
3029 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
3031 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
3032 ext2fs_open_inode_scan): Support dynamically-sized inodes.
3034 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>

3045 the passed in size is *really* too small.
3047 * alloc.c (ext2fs_new_inode):
3048 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
3051 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
3053 * getsize.c (ext2fs_get_device_size): Open the device read-only
3054 when trying to determine its size.
3056 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
3058 * Release of E2fsprogs version 1.02
3060 Sat Dec 9 09:57:50 1995 <tytso@rsts-11.mit.edu>

3063 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3064 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
3065 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
3066 to avoid conflicts with with kernel include files. Also
3067 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
3070 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
3072 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
3074 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around

3081 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
3083 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
3086 * closefs.c: #include <string.h> to pick up memset() declaration
3088 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
3090 * Makefile.in: Added support for BSD shared libraries.
3092 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
3095 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
3097 * unix_io.c (unix_open): Add a double check; if the passed in name
3098 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
3100 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
3102 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
3104 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
3107 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
3109 * getsize.c (ext2fs_get_device_size): Add support for reading the
3110 partition size from a BSD disk label.
3112 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3114 * getsize.c (ext2fs_get_device_size): New function that determins
3115 the size of a device. Used by mke2fs and e2fsck.
3117 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
3119 * Makefile.in (install): Install static libraries in $(ulibdir)
3120 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
3122 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
3124 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
3125 Move these functions to freefs.c.
3127 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
3128 descriptors shadow memory to keep purify quiet. (This
3129 also has the nice benefit that the unused portion of the
3130 shadow descriptors are zeroed out.)
3132 * dirblock.c (ext2fs_write_dir_block): We need to use
3133 dirent->rec_len *before* it's byteswapped to find the
3134 location of the next directory structure!
3136 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
3137 cause ext2fs_new_inode to loop infinitely if we're trying
3138 to allocate an inode in group #0 and there are no free
3139 inodes at all in the system.
3141 * closefs.c: #include <errno.h> if it exists.
3143 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3145 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

3151 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
3152 installation directories correctly.
3154 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>

3157 * mkdir.c (ext2fs_mkdir):
3158 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
3159 to read/write the directory block.
3161 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
3162 file containing functions for reading and writing
3163 directory blocks (byte swapping if necesssary)
3165 * block.c (block_iterate_ind, block_iterate_dind,
3166 block_iterate_tind): Byte swap the block addresses if
3167 EXT2_SWAP_BYTES is set (and swap them back before writing
3170 * inode.c (inocpy_with_swap): New function.
3171 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
3172 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
3174 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
3175 the superblock and group descriptors before writing it out.
3177 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
3178 then set the EXT2_SWAP_BYTES and byte-swap the superblock
3179 and group descriptors.
3181 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
3182 to desp ext2 filesystem structures.
3184 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
3185 supplied by Pete A. Zaitcev so that the C language
3186 versions of these functions are more portable. They will
3187 now work on both little and big endian systems, and the
3188 assumption that 32-bit integers are used is gone.
3190 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
3191 doing byte swapping.
3193 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
3194 byte swapping should take place.
3196 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
3198 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,

3205 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
3207 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
3208 if the magic number is correct, it will be allocated.
3210 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
3212 * block.c (block_iterate_ind, block_iterate_dind,
3213 block_iterate_tind): Don't recompute block_nr each loop;
3214 just increment it! Factor check of BLOCK_FLAG_APPEND out
3215 of the loop. Factor mask of BLOCK_CHANGED into changed
3216 variable out of the loop. (block_iterate_ind, in
3217 particular, gets called a lot, so every little
3218 optimization helps.)
3220 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
3222 * block.c (block_iterate_ind, block_iterate_dind,
3223 block_iterate_tind): Precompute limit of loop to speed up
3224 block_iterate_ind and company.
3226 * bitops.h (ext2fs_fast_mark_block_bitmap,
3227 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
3228 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
3229 ext2fs_fast_test_inode_bitmap): Add fast version of these
3230 functions, which don't do range checking.
3232 * bitops.h (ext2fs_get_block_bitmap_start,
3233 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
3234 ext2fs_get_inode_bitmap_end): Add new accessor functions
3235 which return the start and end points of the bitmaps.
3237 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
3239 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
3240 instead of llseek. The errno if the offset is too large
3241 and lseek is not supported should be EINVAL, not -EINVAL.
3243 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
3245 * Makefile.in: Added support for ELF shared libraries.
3246 Fixed typos in the compilation rules.
3247 (distclean): Added Makefile.
3249 * llseek.c (llseek): New function, if llseek() does not exist in the
3251 (ext2_llseek): Changed to call llseek().
3253 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3255 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
3257 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3259 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
3261 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
3262 the S_*, which are normally defined in <sys/stat.h>. This
3263 allows us to compile e2fsprogs on a non-Linux system,
3264 which may have a different value for S_IFDIR.
3266 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3268 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
3269 this is a user-mode application!
3271 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
3273 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
3274 __linux__ so that non-linux systems won't see it.
3276 * alloc.c: Include <errno.h> if possible.
3277 * badblocks.c: Ditto.
3278 * bb_inode.c: Ditto.
3281 * expanddir.c: Ditto.
3282 * get_pathname.c: Ditto.
3283 * initialize.c: Ditto.
3290 * rw_bitmaps.c: Ditto.
3293 * Makefile.in: Rewritten to conform to GNU coding standards and
3294 support separate compilation directories.
3296 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
3298 * initialize.c (ext2fs_initialize): Don't allow more than one
3299 bitmaps's worth of inodes in a group.
3301 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
3303 * llseek.c (ext2_llseek): Added error checking to the llseek()
3304 compat code to protect against overflow. This only
3305 applies to 1.0 and early 1.1 kernels, which don't support
3306 the llseek() system call.
3308 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
3310 * unix_io.c (unix_open): Initialize the read_error and write_error
3311 io_channel pointers to be null.
3313 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
3314 found, clear it but don't try to update the filesystem
3315 accounting information, since that's hopeless anyway.
3317 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
3318 bloblock_iterate_tind): Check to see if the indirect blocks are
3319 valid before trying to read them.

3322 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
3324 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
3325 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
3326 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
3327 illegal block or inode number is passed in, return instead
3328 of trying to test, set, or clear the bit.
3330 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
3332 * Makefile: Added a dummy install target in case shared libraries
3335 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
3337 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
3338 the real last block of the bitmap should be calculated.

3342 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
3343 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
3344 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
3345 ext2fs_free_block_bitmap): Add magic number checking for
3346 the inode and block bitmaps.
3348 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
3349 magic number for a block bitmap instead of an inode bitmap.

3357 magic number checking for the badblocks_list and
3358 badblocks_iterate structures.
3360 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):

3363 both for io_channel structure and unix_private_data
3366 * openfs.c (ext2fs_open): Add check for io_manager structure's
3369 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,

3389 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
3394 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
3395 openfs.c into its own file.

3398 structure magic numbers.
3400 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
3401 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
3402 someone uses the -b option to specify the use of the backup
3403 superblock --- this usually means that the main superblock is
3407 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
3408 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
3409 revision level to the superblock.
3411 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
3418 * initialize.c: Completely revamped the inode and block bitmap
3419 structures, so that they can be better chance of being extensible
3420 in a shared library. They are now their own type, instead of
3421 being a char *. Also, the function signatures of
3422 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
3423 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
3424 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
3425 changed to eliminate the ext2_filsys argument, since it is no
3428 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
3430 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
3431 system call if available.
3433 * llseek.c: new file. This is the stub calling the llseek system
3434 call which allows supports for 2GB+ file systems.
3436 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
3437 the creator operating system.
3439 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
3441 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
3442 the group descriptor statistics in addition to everything else.
3443 This relieves mke2fs of the responsibility of doing it.
3445 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
3446 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
3447 not the generic C function equivalents should be included or not.
3449 * openfs.c (ext2fs_open): If a superblock is specified, then use
3450 the backup group descriptors that go along with this superblock,
3451 instead of using the primary group descriptors. This allows
3452 e2fsck to recover filesystems where the primary group descriptors
