2
3 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
4 to avoid register conflicts when compiling in PIC mode.
5
Theodore Ts'oac493822001-07-04 14:04:58 -040062001-07-04 Theodore Tso <tytso@valinux.com>
7
8 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
9 Add new functions (C and in i386 assembler) which quickly
10 find bits set in a bitmask.
11
Theodore Ts'o67960132001-06-23 00:16:37 -0400122001-06-23 Theodore Tso <tytso@valinux.com>
13
Theodore Ts'o342d8472001-07-02 11:54:09 -040014 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
15 ext2_ext_attr.h and ext_attr.c for extended attributes
16 support.
17
Theodore Ts'o67960132001-06-23 00:16:37 -040018 * Release of E2fsprogs 1.22
19
Theodore Ts'o89a1fa82001-06-22 20:40:51 -0400202001-06-22 Theodore Tso <tytso@valinux.com>
21
Theodore Ts'ob23520d2001-06-22 21:52:14 -040022 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
23 descriptor so that adding a journal to a mounted
24 filesystem doesn't die. (Fixes a bug accidentally
25 introduced in e2fsprogs 1.21.)
26
Theodore Ts'o78332622001-06-22 21:20:47 -040027 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
28 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
29 fchflags without defining UF_NODUMP. (Addresses Debian
30 bug #101361)
31
Theodore Ts'od90f3492001-06-22 21:01:17 -040032 * flushb.c: Use platform independent method of defining the
33 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
34 since on newer glibc's BLKFLSBUF is defined there.
35
Theodore Ts'o16645f82001-06-22 20:54:11 -040036 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
37 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
38 to support byte swapping even if we don't support the
39 conversion functions. (Fixes Debian bug #101686).
40
Theodore Ts'o89a1fa82001-06-22 20:40:51 -040041 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
42 since the byte-swapping code all assumes the
43 ext2_dir_entry structure. (It's a question of whether or
44 not name_len should be byte-swapped or not, and whether
45 it's a 16 bit or 8 bit field.)

48
Theodore Ts'of4f75ba2001-06-16 01:14:28 +000049 * Release of E2fsprogs 1.21
50
512001-06-15 Theodore Tso <tytso@valinux.com>
52
Theodore Ts'od1e66b72001-06-15 22:44:32 +000053 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
54 file which is generated and is therefore found in the
55 build directory, not source directory.
56
Theodore Ts'o997b8202001-06-15 18:33:43 +000057 * ismounted.c (check_mntent_file): Use a test file in / to check
58 to see if the root filesystem is mounted read-only. This
59 protects against the case where /etc might not be on /, as
60 well as the case where /etc/mtab doesn't exist. (Both are
61 should-never happen scenarios, but you never know...)
62
Theodore Ts'o6bd13482001-06-14 07:00:55 +0000632001-06-14 Theodore Tso <tytso@valinux.com>
64
65 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
66 Remove unneeded #pragma argsused, since the arguments are
67 always used.
68
Theodore Ts'o30ae14c2001-06-13 22:38:56 +0000692001-06-13 Theodore Tso <tytso@valinux.com>
70
Theodore Ts'o65794882001-06-14 00:24:42 +000071 * ext2_types.h.in: If linux/types.h has been defined, then don't
72 try to redefine the typedefs.
73
Theodore Ts'o364a3732001-06-13 23:46:39 +000074 * Makefile.in (HFILES): Add ext2_types.h to the list of files
75 which should be installed.
76
Theodore Ts'o66a46142001-06-13 23:26:19 +000077 * ismounted.c (check_mntent_file): Work around GNU hurd brain
Theodore Ts'o83d5abf2001-06-13 23:31:27 +000078 damage. Addresses Debian bug #100304.
Theodore Ts'o66a46142001-06-13 23:26:19 +000079
Theodore Ts'o30ae14c2001-06-13 22:38:56 +000080 * Makefile.in: Limit some .o files from being included into the
81 library if --disable-debugfs, --disable-swapfs,
82 --disable-imager, or --disable-resizer are used.
83
Theodore Ts'ocbbf0312001-06-13 00:12:04 +0000842001-06-12 Theodore Tso <tytso@valinux.com>
85
86 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
87 function, and use the ext2fs_badblocks_* functions
88 instead.
89
Theodore Ts'o5df55d72001-06-11 07:00:04 +0000902001-06-11 Theodore Tso <tytso@valinux.com>
91
Theodore Ts'o3034f622001-06-11 15:17:45 +000092 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
93 ext2fs_mark_generic_bitmap and
94 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
95 functions. (This saves space and doesn't significantly
96 change the speed of e2fsck on a P-III.)
97
Theodore Ts'o5df55d72001-06-11 07:00:04 +000098 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
99 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
100 include the byte-swapping logic if ENABLE_SWAPFS is turned
101 on or if we're on a big-endian machine.
102
103 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
104 set EXT2_FLAG_SWAP_BYTES, instead of using
105 ext2fs_native_flag.
106
107 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
108 autoconf to determine whether or not return
109 EXT2_FLAG_SWAP_BYTES.
110
Theodore Ts'o349a4842001-06-11 00:49:29 +00001112001-06-10 Theodore Tso <tytso@valinux.com>
112
113 * Makefile.in: Remove the dependence on the libe2p library.
114
115 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
116 with direct usage of the ioctl/fchflags so that we don't
117 have to depend on the libe2p library.
118
Theodore Ts'o30e50b72001-06-08 09:43:40 +00001192001-06-08 Theodore Tso <tytso@valinux.com>
120
121 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
122 when trying to find a 32-bit wide type.
123
124 * icount.c (insert_icount_el): Fix the code used to estimate the
125 size of the new icount array to be more intelligent, to
126 avoid reallocating the array too many times. Thanks to
127 Enrique Perez-Terron for pointing this out.
128
Theodore Ts'of36d14f2001-06-02 04:13:16 +00001292001-06-02 Theodore Tso <tytso@valinux.com>
130
131 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
132 for a symlink to determine whether it is a fast symlink.
133
Theodore Ts'o797f5ef2001-06-01 23:49:46 +00001342001-06-01 Theodore Tso <tytso@valinux.com>
135
136 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
Theodore Ts'o36a23e12001-06-02 00:54:10 +0000137 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.

140
Theodore Ts'obb185862001-05-25 17:35:00 +0000141 * Release of E2fsprogs 1.20
142
1432001-05-25 Theodore Tso <tytso@valinux.com>
144
Theodore Ts'od5f858d2001-05-25 17:14:23 +0000145 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
146 some to clean up Andreas's patches. Use strncpy instead
147 of strcpy to save the root's mountpoint. Clean up #ifdef
148 structure. Remove uneeded variable in testing/debug driver.
149
Theodore Ts'occ860172001-05-25 16:32:53 +00001502001-05-24 Andreas Dilger <adilger@turbolinux.com>
151
152 * ismounted.c: Add check for root device which doesn't depend on
153 /etc/fstab or /proc/mounts to be correct. Don't call
154 endmntent() before we are done with mnt struct.
155
Theodore Ts'o4ed8ebe2001-05-23 18:30:10 +00001562001-05-23 Theodore Tso <tytso@valinux.com>
157
158 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
159 code.
160
Theodore Ts'ob10820c2001-05-21 05:23:31 +00001612001-05-21 Theodore Tso <tytso@valinux.com>
162
163 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
164 make room for pre-existing usage of
165 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
166 the same codepoint as EXT2_BTREE_FL.
167
Theodore Ts'o7c2d2562001-05-21 02:54:21 +00001682001-05-20 Theodore Tso <tytso@valinux.com>
169
170 * ext2fs.h: #include <> instead of "" for ext2fs and et header
171 files, since they will be installed in /usr/include
172
Theodore Ts'o7a34cb02001-05-14 04:28:35 +00001732001-05-14 Theodore Tso <tytso@valinux.com>
174
Theodore Ts'o9f8046f2001-05-14 11:35:52 +0000175 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
176 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

187 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
188 Adjust all files in this directroy to include this file.
189
Theodore Ts'o7a34cb02001-05-14 04:28:35 +0000190 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
191 code.
192
Theodore Ts'o0f679452001-05-05 16:42:24 +00001932001-05-05 Theodore Tso <tytso@valinux.com>
194
195 * fileio.c (ext2fs_file_read): Factored out common code and
196 cleaned up function. Fixed a bug where if there was an
197 error reading from the disk, the number of bytes read
198 wasn't reliably set. (Fixes Debian bug #79163)
199 (ext2fs_file_write): Factored out common code and made
200 function more efficient; if writing a full block, don't
201 bother to do a read-modify-write cycle.
202
Theodore Ts'o1cca4d62001-05-05 05:12:14 +00002032001-05-04 Theodore Tso <tytso@valinux.com>
204
205 * dirblock.c (ext2fs_read_dir_block): Check for an directory
206 record length which isn't a multiple four, and treat that
207 as an invalid. Scan the directory and return an error
208 (EXT2_ET_DIR_CORRUPTED) if the directory records are
209 corrupted.
210 (ext2fs_write_dir_block): If while byte-swapping the
211 directory block, if there's an error, abort and return
212 EXT2_ET_DIR_CORRUPTED.
213
Theodore Ts'oa78926e2001-05-03 04:02:29 +00002142001-05-02 Theodore Tso <tytso@valinux.com>
215
216 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
217 image_header field in the ext2_filsys structure
218
219 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
220 * inode.c (ext2fs_read_inode):
221 * rw_bitmaps.c (read_bitmaps):
222 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
223
224 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
225 sure the full bitmap is saved.
226
Theodore Ts'of955cc12001-05-01 19:04:28 +00002272001-05-01 Theodore Tso <tytso@valinux.com>
228
Theodore Ts'oa78926e2001-05-03 04:02:29 +0000229 * e2image.h (struct ext2_image_hdr): Add space for the device name
230 in the image header.
231
Theodore Ts'of955cc12001-05-01 19:04:28 +0000232 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
233 make sure the rec_len is a multiple of 4, to prevent
234 bus-errors on architectures which care about mis-aligned
235 pointer references.
236
Theodore Ts'o954a6832001-04-26 01:42:37 +00002372001-04-25 Theodore Tso <tytso@valinux.com>
238
239 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
240 query the device sizes using the BLKGETSIZE ioctl.
241
Theodore Ts'o03603942001-04-17 00:53:25 +00002422001-04-16 Theodore Tso <tytso@valinux.com>
243
Theodore Ts'o52db0b42001-04-17 02:22:05 +0000244 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
245 before checking /etc/mtab. The EXT2_MF_READONLY flag is
246 now set from the /etc/mtab options field for all
247 filesystems, not just the root filesystem. Add debugging
248 code to make it easier to test ext2fs_check_if_mounted().
249
Theodore Ts'o03603942001-04-17 00:53:25 +0000250 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
251 check; return an error if there's an attempt to create a
252 journal less than 1024 filesystem blocks.
253
254 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
255 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
256
Theodore Ts'o9ec53cf2001-02-20 16:28:40 +00002572001-02-20 Theodore Tso <tytso@valinux.com>
258
259 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
260 inline functions.
261
262 * tst_byteswap.c: New function to test the byteswap functions.
263 Add to regression test suite.
264
Theodore Ts'oc5423c52001-02-08 05:45:17 +00002652001-02-08 Theodore Tso <tytso@valinux.com>
266
267 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
268
Theodore Ts'od23042a2001-02-08 03:37:16 +00002692001-02-07 Theodore Tso <tytso@valinux.com>
270
271 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
272 of s_first for external devices to always be 1, since
273 jsb->s_first is always relative to the start of the
274 journal superblock. Use htonl(1) when setting s_nr_users.
275
Theodore Ts'o02088862001-01-18 01:44:19 +00002762001-01-17 Theodore Ts'o <tytso@valinux.com>
277
278 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
279 device number of the filesystem (instead of the journal)
280 was being dropped into s_journal_dev.
281
Theodore Ts'oa1128472001-01-16 06:56:14 +00002822001-01-15 Theodore Ts'o <tytso@valinux.com>
283
284 * initialize.c (ext2fs_initialize): Add support for initializing
285 the ext2 superblock for external journal devices. This
286 basically means we don't bother to allocate any block
287 group descriptors.
288
289 * openfs.c (ext2fs_open): Only open external journal devices if
290 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
291 ext2fs_open. When opening such devices, don't try to read
292 the block group descriptors, since they're not there.
293
294 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
295
296 * mkjournal.c: Export a new function,
297 ext2fs_create_journal_superblock(), which allocates and
298 returns a buffer containing a journal superblock. This is
299 needed by mke2fs to create an external journal. Rewrote
300 ext2fs_add_journal_device() so that it no longer creates
301 the external journal, but rather adds a filesystem to an
302 existing external journal. It handles all of the UUID
303 manipulation.
304
305 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
306 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
307 Changed function prototype for ext2fs_add_journal_device().
308
Theodore Ts'o80779942001-01-14 18:03:43 +00003092001-01-14 Theodore Ts'o <tytso@valinux.com>
310
311 * closefs.c (ext2fs_flush): Don't write out anything beyond the
312 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
313 listed.
314
Theodore Ts'ob94bd812001-01-12 17:26:05 +00003152001-01-12 Theodore Ts'o <tytso@valinux.com>
316
317 * imager.c: Fix gcc -Wall complaints and a series of bugs where
318 retval wasn't set correctly. (Thanks to Andreas Dilger
319 for pointing this out.)
320
Theodore Ts'o4d0f3e12001-01-11 15:48:50 +00003212001-01-11 <tytso@snap.thunk.org>
322
323 * flushb.c (ext2fs_sync_device): New function which centralizes
324 all of the places which might try to use the BLKFLSBUF
325 or FDFLUSH ioctls (and usually failing to define them
326 since the system header files don't usually do this for
327 us, and we're trying to avoid usage of kernel include
328 files now).
329
Theodore Ts'o31dbecd2001-01-11 04:54:39 +00003302001-01-10 <tytso@snap.thunk.org>
331
332 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
333 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
334 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
335 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
336 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
337 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
338 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
339 ext2_ino_t, to protect applications that attempt to
340 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
341 changes ino_t(!?). So we use ext2_ino_t to avoid an
342 unexpected ABI change.

345
Theodore Ts'oe446d712001-01-05 22:27:06 +0000346 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
347 we may overrun allocated memory in case of a corrupted
348 filesystem (or an e2fsck test case :-) when byte-swapping
349 the directory block.
350
Theodore Ts'ocdaf1fa2001-01-05 22:23:22 +0000351 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
352
353 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
354 complaints including a missing return 0 at the end of
355 ext2fs_add_journal_device.
356
Theodore Ts'o43ec8732001-01-03 14:56:46 +00003572001-01-03 <tytso@snap.thunk.org>
358
Theodore Ts'o4becab62001-01-03 19:22:42 +0000359 * Makefile.in: Link in libe2p when creating libext2fs as a shared
360 library, since mkjournal.c now references fsetflags().
361
362 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
363 Dilger's changes (with fixups) to allow on-line creation
364 of a journal file.
365
Theodore Ts'o43ec8732001-01-03 14:56:46 +0000366 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
367 EXT2_FLAG_SUPER_ONLY, which the close routines to only
368 update the superblock, and not the group descriptors.
369
3702000-12-30 Andreas Dilger <adilger@turbolinux.com>
371
372 * ismounted.c: add ext2fs_check_mount_point() function, which will
373 optionally return the mount point of a device if mounted
374
Theodore Ts'o31a17b32001-01-03 13:04:12 +00003752000-12-14 Andreas Dilger <adilger@turbolinux.com>
376
377 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
378 ext2fs_add_journal_inode()
379
Theodore Ts'oe5b38a52001-01-01 16:17:12 +00003802001-01-01 <tytso@snap.thunk.org>
381
382 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
383 source (but not binary) compatibility of some users of the
384 ext2 library. They should just simply do a global search
385 and replace of struct ext2fs_sb with struct
386 ext2_super_block, and use their own private copy of
387 ext2_fs.h if they aren't already.
388
389 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
390 Replace use of ext2fs_sb with ext2_super_block.
391
Theodore Ts'o2fe1efe2000-12-31 13:39:17 +00003922000-12-31 <tytso@snap.thunk.org>
393
394 * ext2fs.h: Cleaned up header file by removing definitions of
395 feature flags that might not have been defined in older
396 ext2 header files. Now that we're using our own
397 include/linux/ext2fs.h header file, this can never happen.
398
399 * jfs_dat.h: Removed old header file which is no longer needed.
400
Theodore Ts'o7dcfa6e2000-12-13 17:50:14 +00004012000-12-13 Theodore Ts'o <tytso@valinux.com>
402
Theodore Ts'oa917d1c2000-12-13 18:36:23 +0000403 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
Theodore Ts'o3fe973b2000-12-13 17:55:49 +0000404 by Andreas Dilger to update the filesystem revision to
405 EXT2_DYNAMIC_REV.
406
Theodore Ts'o7dcfa6e2000-12-13 17:50:14 +0000407 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
408 fields.
409
Theodore Ts'o58618732000-12-09 05:47:45 +00004102000-12-09 <tytso@snap.thunk.org>
411
Theodore Ts'o31a17b32001-01-03 13:04:12 +0000412 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
Theodore Ts'o4e246702000-12-09 14:39:16 +0000413 ext2fs_add_journal_device): Add a new argument to the APIs
414 of these function, which is a flags word. This is used to
415 allow the creation of a V1 superblock for those folks who
416 are using ext3 0.3b in production. Note, the user-land
417 interface for getting at this flag won't be documented, as
418 the V1 superblock is deprecated.
419
Theodore Ts'o58618732000-12-09 05:47:45 +0000420 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
421 which creates a V2 superblock instead of a V1 superblock.
422
Theodore Ts'of20d0d52000-12-05 03:53:41 +00004232000-11-21 <tytso@snap.thunk.org>
424
425 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
426 out by Andreas Dilger.
427
Theodore Ts'o72ed1262000-11-12 19:32:20 +00004282000-11-05 <tytso@snap.thunk.org>
429
430 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
431 ext2_fs.h, Makefile.in: New file that has routines that
432 save ext2fs metadata to a file.
433
434 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
435
436 * e2image.h: New file which defines the file format for the ext2
437 image file. (Saved copy of ext2 metadata to a file as a
438 saving throw against worst-case damage.)
439
Theodore Ts'o6a7f4552000-11-12 19:07:06 +00004402000-11-01 <tytso@snap.thunk.org>
441
442 * inode.c (ext2fs_flush_icache): Add new function
443 ext2fs_flush_icache() which flushes the internal inode
444 cache. Applications which modify the inode table blocks
445 directly must call this function.
446
Theodore Ts'oc180ac82000-10-26 20:24:43 +00004472000-10-26 <tytso@snap.thunk.org>
448
Theodore Ts'o17ee8b12000-10-26 20:45:58 +0000449 * mkjournal.c: Add #include of netinet/in.h, since Solaris
450 requires it for ntohl().
451
Theodore Ts'oc180ac82000-10-26 20:24:43 +0000452 * ext2_io.h (io_channel_write_byte): Add new interface to allow
453 callers to write specific byte ranges. This is an
454 optional interface, which not all IO channels may
455 implement.
456
457 * unix_io.c (unix_write_byte):
458 * test_io.c (test_write_byte): Add implementation of the
459 write_byte function.
460
461 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
462 function which writes the primary superblock. If the IO
463 channel supports writing raw bytes directly, only fields
464 which were modified are written to the disk. This makes
465 it safe(r) to use utilities like tune2fs on a mounted
466 filesystem.
467
468 * freefs.c (ext2fs_free): Free the original superblock if it is
469 available.
470
471 * openfs.c (ext2fs_open): Store a copy of the original superblock
472 when opening it.
473
474 * ext2fs.h: Add a field to store the original superblock in the
475 ext2 context structure.
476
Theodore Ts'o43819662000-10-25 02:06:09 +00004772000-10-24 <tytso@snap.thunk.org>
478
479 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
480 don't need to use llseek).
481
Theodore Ts'od3cd93c2000-10-24 18:33:16 +00004822000-10-24 <tytso@valinux.com>
483
484 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
485 creating an ext3 journal on a filesystem.
486
4872000-08-21 <tytso@valinux.com>
488
489 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
490
Theodore Ts'oadfc8c62000-10-18 19:22:24 +00004912000-08-22 <tytso@valinux.com>
492
493 * unix_io.c: Make massive changes to support a multiple block
494 writethrough cacheing.
495
496 * ext2_io.h: Added flags field to the io_channel structure.
497
Theodore Ts'ode23aa12000-08-19 17:00:47 +00004982000-08-19 <tytso@valinux.com>
499
500 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
501 provides the function ext2fs_find_block_device(). This
502 function returns the pathname to a block device, given its
503 device number.
504
Theodore Ts'of9e67062000-07-13 23:25:54 +00005052000-07-13 <tytso@valinux.com>
506
507 * Release of E2fsprogs 1.19
508
Theodore Ts'oab146762000-07-07 04:37:35 +00005092000-07-07 Theodore Ts'o <tytso@valinux.com>
510
511 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
512 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
513 list of filesystem flags supported by the library.
514
Theodore Ts'o57dca852000-07-04 19:20:25 +00005152000-07-04 Theodore Ts'o <tytso@valinux.com>
516
Theodore Ts'o8f13d8c2000-07-04 19:41:29 +0000517 * ext2fs.h: Update to include latest journalling additions to the
518 superblock.
519
Theodore Ts'o57dca852000-07-04 19:20:25 +0000520 * dll/jump.funcs: Add new jumptable entries for
521 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
522 ext2fs_badblocks_equal.
523
524 * tst_badblocks.c: Update test program to test
525 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
526
527 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
528 writes out bad blocks list to a file.
529
530 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
531 changes the callback function to take two additional
532 arguments; a private blind pointer supplied by the caller,
533 and pointer to a char * containing a pointer to the
534 invalid string.
535
536 * badblocks.c (ext2fs_badblocks_equal): Add new function which
537 returns true if two badblocks list are equal.
538
539 * Makefile.in: Remove explicit link of -lc in the shared library.
540 (It shouldn't be necessary, and is harmful in some cases).
541
Theodore Ts'oabf7d382000-06-10 19:27:17 +00005422000-06-10 Theodore Ts'o <tytso@valinux.com>
543
544 * getsize.c (main): Add debugging code under #ifdef DEBUG
545
Theodore Ts'o2e8d40d2000-05-27 15:15:40 +00005462000-05-27 Theodore Ts'o <tytso@valinux.com>
547
548 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
549 earlier, so that if there's an error reading it, we can
550 more cleanly back out of the operation.
551
Theodore Ts'of0f4acb2000-05-25 23:22:11 +00005522000-05-25 <tytso@snap.thunk.org>
553
Theodore Ts'odc5f68c2000-05-25 23:31:54 +0000554 * getsize.c (ext2fs_get_device_size): Use open64() instead of
Theodore Ts'o7fd86d32000-05-25 23:42:22 +0000555 open() if it exists. Under linux, manually define the
556 ioctl for BLKGETSIZE if it isn't already defined and it's
557 safe to do so.
Theodore Ts'odc5f68c2000-05-25 23:31:54 +0000558
559 * unix_io.c (unix_open): Use open64() instead of open() if it
560 exists.
561
562 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
563 available (and prototypes are defined) use it in
564 preference to llseek.
565
Theodore Ts'of0f4acb2000-05-25 23:22:11 +0000566 * Makefile: Add hack dependency rule so that parallel makes work
567 correctly.
568

574
Theodore Ts'o06af47f2000-04-03 13:51:00 +0000575 * block.c: Readibility tweak in conditionals involving
576 ctx->fs->flags.
577
Theodore Ts'oe589f672000-04-03 13:45:40 +0000578 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
579 how to define __s64 and __u64. Turn off "compression is
580 experimental" warning if the cpp macro
581 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
582
Theodore Ts'o2c1a0ce2000-02-11 15:39:19 +00005832000-02-11 <tytso@snap.thunk.org>
584
Theodore Ts'o5a63dd22000-02-11 15:44:08 +0000585 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
586 Conditionally include Compression as a supported type if
587 ENABLE_COMPRESSION (via --enable-compression) is turned on.
588
Theodore Ts'o2c1a0ce2000-02-11 15:39:19 +0000589 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
590
Theodore Ts'o28ffafb2000-02-08 19:14:02 +00005912000-02-08 <tytso@snap.thunk.org>
592
593 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
594 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
595 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
596 Change to return the previous state of the bit that is
597 being marked or unmarked. For speed optimization.
598
Theodore Ts'o80e808f2000-02-02 16:19:59 +00005992000-02-02 Theodore Ts'o <tytso@valinux.com>
600
601 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
602
603 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
604 needed any more; we know it will always be i_generation.
605 Add support for swapping the high bits of the uid and gid.
606

621
622 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
623 since ext2fs_badblocks_list_free was moved to freefs.c.
624
625 * tst_badblocks.c: Use the newer badblocks API names. Add
626 duplicate blocks to the test inputs to test dealing with
627 adding blocks which are already in the badblocks list.
628
629 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
630 of the list, use a shortcut O(1) operations instead of an
631 O(n) operation. (Idea suggested by David Beattie.)
632
633 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
634 of badblocks_list_free(), to save a procedure call.
635

641
Theodore Ts'o416c93d1999-10-26 04:49:54 +0000642 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
643 seem to handle ~0UL the same way as they used to.
644
Theodore Ts'o601002b1999-10-26 02:06:39 +00006451999-10-25 <tytso@valinux.com>
646
Theodore Ts'ofe70fd31999-10-26 02:34:47 +0000647 * nt_io.c (_OpenNtName): Open the device using
648 FILE_SYNCHRONOUS_IO_NONALERT instead of
649 FILE_SYNCHRONOUS_IO_ALERT
650 (nt_open): At the end of the device open routine, unlock
651 the drive but do not dismount it.
652
Theodore Ts'o601002b1999-10-26 02:06:39 +0000653 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
654 detect the Hurd OS.
655

661
Theodore Ts'oe6198e51999-10-23 00:58:54 +0000662 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
663
664 * link.c (ext2fs_link): This call now uses the low three bits of
665 the flags parameter to pass the directory filetype
666 information; it will set the directory entry FILETYPE
667 information if the filesystem supports it.
668
669 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
670 option is set, then create the '.' and '..' entries with
671 the filetype set to EXT2_FT_DIR.
672
Theodore Ts'oaa4115a1999-10-21 19:33:18 +00006731999-09-24 <tytso@valinux.com>

678
679 * ext2fs.h: Add new fields for journalling and define new
680 feature bits used by newer filesystems: IMAGIC_INODES,
681 HAS_JOURNAL, RECOVER.
682
683 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
684 we update the inode block count and size files so that the
685 block count field is updated correctly when we create an
686 indirect block.
687
6881999-07-18 Theodore Ts'o <tytso@valinux.com>

693
694 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
695 kernels that use i_generation instead of i_version. Patch
696 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
697
6981999-06-21 <tytso@valinux.com>
Theodore Ts'o813bbb21999-06-22 03:17:45 +0000699
700 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
701 directory entry before calling the callback function.
702 This should prevent some core dumps of insufficiently

706
707 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
708
709 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
710 that we don't handle writing yet (we do). Fixed bug where
711 we weren't allocating a big enough buffer for ext2_bmap.
712
Theodore Ts'of0687a51999-05-29 21:48:03 +00007131999-05-03 <tytso@rsts-11.mit.edu>
714
715 * openfs.c (ext2fs_open): Check to make sure that the number of
716 blocks per group is not zero --- if so, it must be a bad
717 superblock!
718
Theodore Ts'o9e51eca1999-01-09 16:32:31 +00007191999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>

724
725 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
726 the inode number is zero; if it's zero, return
727 EXT2_ET_BAD_INODE_NUM.
728
Theodore Ts'o7a469521999-01-04 08:50:59 +00007291998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
730
731 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
732 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
733 header files.
734
Theodore Ts'o73f17cf1999-01-04 07:35:45 +0000735Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
736
737 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
738 non-Linux case to use EINVAL by default, unless it isn't
739 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
740 instead.
741

751
752 * initialize.c (ext2fs_initialize): Make sure that we allocate
753 enough inodes so that we can make a valid filesystem.
754
Theodore Ts'o2eb374c1998-09-03 01:22:57 +00007551998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
756
757 * rw_bitmaps.c: Fixed signed/unsigned warnings.
758
759 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
760 function declaration.
761
762 * dblist.c (make_dblist): Add safety check in case the dblist
763 pointer passed in is null (in which case, assign it to
764 fs->dblist). Fixed some signed/unsigned warnings.
765
766 * bmap.c: Make addr_per_block be of type blk_t to avoid
767 signed/unsigned warnings.
768
769 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
770 function declaration.
771
772 * get_pathname.c (get_pathname_proc): Use return value from
773 ext2fs_get_mem, instead of checking if &gp->name is
774 NULL.
775
776 * dir_iterate.c (ext2fs_process_dir_block):
777 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
778 from the function declaration.
779
780 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
781 return the error directly instead of jumping to the
782 cleanup routine, since we don't need to do any cleanup.
783
784 * alloc_table.c (ext2fs_allocate_group_table): Make this
785 function take a dgrp_t for its group argument.
786
787 * ext2fs.h: Make dgrp_t an __u32 type, and make
788 fs->desc_group_count be of type dgrp_t.
789
Theodore Ts'of75c28d1998-08-01 04:18:06 +00007901998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
791
792 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
793 than 10 blocks when we need to expand the size of the
794 badblocks list.
795
Theodore Ts'o4a5fa191998-07-09 05:42:45 +00007961998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>

801
802 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
803 appropriate for all of the block group copies, so that
804 it's clear where the beginning of the filesystem is on the
805 disk. (For when the partition table gets scrod.)
806
807 * ext2fs.h: Change the name of the feature from
808 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
809 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
810
Theodore Ts'o818180c1998-06-27 05:11:14 +00008111998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
812
813 * inode.c (get_next_blockgroup): Fix bug where if
814 get_next_blockgroup() is called early because of a missing
815 inode table in a block group, the current_inode counter
816 wasn't incremented correctly.
817
Theodore Ts'o4faba5b1998-06-16 05:23:41 +00008181998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
819
820 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
821 against a completely trashed bad block inode.
822
Theodore Ts'o03673db1998-06-10 20:39:43 +00008231998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
824
825 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
826 the stride length hits a bad value, we retry the block
827 allocation starting at the beginning of the block group.
828
829 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
830 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
831 e2_blkcnt_t to avoid collision with LFS API.
832
Theodore Ts'o353952d1998-05-01 05:32:18 +00008331998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
834
835 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
836 way that avoids overflows on disk sizes greater than 4GB.
837
Theodore Ts'o4c77fe51998-04-30 17:35:59 +00008381998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
839
840 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
841 return type for comparison functions for qsort.
842
843 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
844 declaration.
845
Theodore Ts'o76f875d1998-04-27 01:41:13 +00008461998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
847
848 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
849 inline functions.
850
851 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
852 evade a potential problem with glibc's header files trying
853 to spike out linux/types.h.
854
855 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
856 include the old size of the memory, which is needed for
857 some braindamaged memory allocation systems that don't
858 support realloc().
859
860 * badblocks.c (ext2fs_badblocks_list_add):
861 bb_inode.c (clear_bad_block_proc):
862 dblist.c (ext2fs_add_dir_block):
863 icount.c (insert_icount_el):
864 irel_ma.c (ima_put):
865 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
866 pass the old size of the memory to be resized to
867 ext2fs_resize_mem().
868
Theodore Ts'o469bec81998-04-01 02:46:43 +00008691998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
870
871 * Makefile.in: Change to use new installation directory variables
872 convention. Fix uninstall rules to take $(DESTDIR) into
873 account.
874
Theodore Ts'o4a31c481998-03-30 01:27:25 +00008751998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
876
877 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
878 with 32 bit longs, then we need to manually define __s64
879 and __u64, since the current kernel header files don't
880 define these if __STRICT_ANSI__ is defined. This is a
881 problem if we are compiling with full GCC warnings, since
882 we do need 64 bit support.
883
884 * Makefile.in (OBJS): Remove bmove.o from files to be built,
885 since we're not using ext2fs_move_blocks() and there
886 is some question as to its usefulness in its current
887 form.
888
889 * bmap.c (block_bmap): Remove unused function.
890
891 * bmove.c (process_block): Fix -Wall warning.
892
Theodore Ts'o36a43d61998-03-24 16:17:51 +00008931998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
894
895 * block.c (ext2fs_block_iterate3): Make the ref_offset field
896 contain the offset into the inode.i_blocks array when
897 ref_block is zero. Since we haven't done a formal
898 release of e2fsprogs since block_iterate2 was first
899 introduced, I removed block_iterate2, and renamed
900 block_iterate3 to be block_iterate2.
901
902 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
903 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
904 use of block_iterate and block_iterate2 to
905 block_iterate2 with the new prototype for the
906 interator function. (using blkcnt_t forr blockcount)
907
Theodore Ts'o674a4ee1998-03-23 02:06:52 +00009081998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
909
910 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
911 s_prealloc_blocks, s_prealloc_dir_blocks). Added
912 conditional defines of new features COMPAT_DIR_PREALLOC,
913 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
914 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
915 the library to declare that we support COMPAT_DIR_PREALLOC,
916 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
917
918 * fileio.c: Rename function ext2fs_file_llseek to be
919 ext2fs_file_lseek, which is more accurate.
920
921 * block.c: Add new function ext2fs_block_iterate3 which calls
922 the iterator function with the blockcount argument of
923 type blkcnt_t. This version of the function is
924 allowed to handle large files; the other fucntions are
925 not.
926
927 * ext2fs.h: Add new type blkcnt_t
928
929 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
930
931 * block.c (ext2fs_block_iterate2): Fix bug where the block count
932 field wasn't getting correctly incremented for sparse
933 files when the indirect or doubly-indirect block
934 specified in the inode was zero.
935
936Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
937
938 * unlink.c (unlink_proc):
939 * lookup.c (lookup_proc):
940 * link.c (link_proc):
941 * get_pathname.c (get_pathname_proc):
942 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
943 from dirent->name_len, so it can be used for other
944 purposes.
945
946 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
947 and indicate that we have support for this incompatible
948 option.
949
Theodore Ts'oc7752561998-02-24 04:25:52 +0000950Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
951
952 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
953

955
956 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
957 number of directories when the block group information is
958 unreliable.
959
Theodore Ts'oc4e749a1998-02-20 05:33:14 +00009601998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
961
Theodore Ts'o218a4861998-02-21 01:41:39 +0000962 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
963 inode table is missing so that we catch the case where the
964 first block group is missing.
965
Theodore Ts'oc4e749a1998-02-20 05:33:14 +0000966 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
967 needed.
968
Theodore Ts'o9abd2ce1998-02-16 22:00:37 +0000969Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
970
971 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
972
973 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
974
975 * test_io.c (test_flush): Add a debugging printf when the flush
976 method is called.
977
978 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
979 read in, return right away.
980
Theodore Ts'o5953b9d1998-02-01 13:23:02 +0000981Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
982
983 * bitops.h: Don't try to do i386 inline asm functions if the
984 compiler isn't GCC.
985
986 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
987 instead of linux/types.h, and e2_bitops.h instead of
988 ext2fs/bitops.h.
989
990 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
991 necessary.
992
Theodore Ts'ob5abe6f1998-01-19 14:47:53 +0000993Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
994
995 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
996 so that we don't need to call get_next_blockgroup() the
997 first time around. Saves a bit of time, and prevents us
998 from needing to assign -1 to current_group (which is an
999 unsigned value).
1000
1001 * icount.c (insert_icount_el): Cast the estimated number of inodes
1002 from a float to an ino_t.
1003
1004 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

1014 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1015 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
1016 defined, then assume all of the
1017 ext2-specific header files are in a flat directory.
1018
1019 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1020 all assignments from void * to be compatible with C++.
1021
1022Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1023
1024 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
1025 make sure the contents of the disk are flushed to disk.
1026
1027Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1028
1029 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
1030 avoid C++ namespace clash.
1031
1032 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
1033 avoid C++ namespace clash.
1034
1035 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
1036 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
1037 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
1038 unlink.c: Change private to be priv_data (to avoid C++
1039 namespace clash)
1040
Theodore Ts'o5be8dc21997-12-01 18:24:10 +00001041Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1042
1043 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1044 paranoid about validating the directory counts from the
1045 block group information.
1046
1047 * all files: Don't include stdlib.h anymore; include it in
1048 ext2_fs.h, since that file requires stdlib.h
1049
Theodore Ts'o89270b51997-11-24 11:44:25 +00001050Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1051
1052 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1053 bitmap is loaded, and return an error if it is not.
1054 (expand_dir_proc): Only use ext2fs_write_dir_block when
1055 writing a directory block, not when writing out a fresh
1056 indirect block.
1057

1061 the ext2fs_get_device_size function.
1062
1063 * ext2_err.et.in (EXT2_ET_UNIMPLEMENTED): Added new error code.
1064

1072
1073Fri Oct 31 12:16:52 1997 <tytso@EDT.MIT.EDU>
1074
1075 * bitops.c (ext2fs_warn_bitmap, ext2fs_warn_bitmap2): Don't call
1076 com_err if OMIT_COM_ERR is defined.
1077

1079
1080 * Rename new error codes to _ET_ in them for consistency.

Theodore Ts'o7b4e4531997-10-26 03:41:24 +00001084 * [all files, basically]: Added definition of ext2fs_get_mem,
1085 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1086 changed all library routines to use these wrapper functions.
1087
Theodore Ts'o78d8f901997-10-26 01:53:39 +00001088 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
1089 instead of the system error messages.
1090
1091 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
1092 EXT2_DB_NOT_FOUND
1093
Theodore Ts'o30fab291997-10-25 22:37:42 +00001094 * ext2fs.h: Added function declarations and constants for bmap.c
1095 and fileio.c.

1146
1147 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the

1173 to make life easer for GNU Libc 2.
1174
1175 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1176 filesystem has its bitmaps stored as 32-bit words with bit
1177 0 as the LSB of each word. Thus a bitmap with only bit 0
1178 set would be, as a string of bytes, 00 00 00 01 00 ... To
1179 cope with this, we byte-reverse each word of a bitmap if
1180 we have a big-endian filesystem, that is, if we are *not*
1181 byte-swapping other word-sized numbers.
1182
Theodore Ts'o3cb6c501997-08-11 20:29:22 +00001183Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1286
1287 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1288 wasn't being returned to the caller.
1289
1290 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1291 ext2fs_allocate_group_table() which sets the group tables
1292 for a particular block group. The relevant code was
1293 factored out of ext2fs_allocate_tables().
1294
1295 * dblist.c (make_dblist): Adjust the initial size of the directory
Theodore Ts'o024996c1997-06-17 05:38:35 +00001296 block list to be a bit more realistic (ten plus twice the
Theodore Ts'o1e1da291997-06-09 14:51:29 +00001297 number of directories in the filesystem).
1298
Theodore Ts'of635d7f1997-05-09 02:50:16 +00001299Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1300
1301 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1302 ext2fs_badblocks_list_test would test the list (and exceed
1303 array boundaries) if there were no bad blocks on the bad
1304 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1305
Theodore Ts'oa29f4d31997-04-29 21:26:48 +00001306Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1307
1308 * Release of E2fsprogs version 1.10
1309
1310Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1311
1312 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1313 inode and block bitmaps based on the RAID 0 stride
1314 parameter (which is passed by mke2fs).
1315
1316 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1317 mke2fs to communicate the stride length to
1318 ext2fs_allocate_tables()
1319
1320Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1321
1322 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1323 systems. (We can't assume that the new filesystem types

1326Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1327
1328 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we

1330 all times.
1331
1332Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1333
1334 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1335 filesystem has no free blocks, ext2fs_new_block would loop
1336 forever.
1337
1338 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1339
1340 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1341 free if refcount goes to zero.
1342
1343 * inode.c (create_icache): Initialize refcount to 1.
1344
1345 * ext2fsP.h: Added refcount to ext2_inode_cache

1351 badblocks structure.
1352
1353Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1354
1355 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
1356

1364
1365Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1366
1367 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1368 cache in the filesystem handle, instead of the inode cache
1369 in a static variable.
1370
1371 * freefs.c: Added static function to free the inode cache (called by
1372 ext2fs_free).
1373
1374 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1375
1376 * ext2fs.h: Added pointer to the inode_cache structure.

1388
1389 * version.c (ext2fs_parse_version_string): Check the passed in
1390 version string (instead of the hard-coded one).
1391
1392 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1393 greater filesystem size, clamp it to prevent allocating a
1394 block or inode bitmap beyond the filesystem.
1395
1396 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1397 overhead calculation was accidentally removed.
1398
1399Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1400
1401 * Release of E2fsprogs version 1.08
1402

1404
1405 * dblist.c (ext2fs_set_dir_block): New function which sets the
1406 block of a dblist entry, given the directory inode and
1407 blockcnt.
1408
1409Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1410
1411 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1412 inode bitmaps at staggered locations across the block
1413 groups, to avoid concentrating the bitmaps on a small
1414 number of disks when using striped RAID arrays.
1415
1416 * initialize.c (ext2fs_initialize): By default, choose the maximum
1417 possible number of blocks per group (based on the size of
1418 the bitmaps in the blocksize).
1419
1420Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1421
1422 * initialize.c (ext2fs_initialize): Add support for
1423 EXT2_COMPAT_SPARSE_SUPER feature.
1424
1425 * closefs.c (ext2fs_bg_has_super): New function to determine
1426 whether or a particular block group should have a
1427 superblock and block group descriptor. Used for the
1428 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1429 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1430 or not the superblock should be written out for the block
1431 group.
1432

1434 for sparse duplicate superblocks.
1435
1436 * version.c (ext2fs_get_library_version): New function which
1437 returns the library version.
1438
1439 * version.c (ext2fs_parse_version_string): New function which
1440 parses a version string and returns a version number,
1441 so application programs can compare version numbers as
1442 integers.
1443
1444Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1445
1446 * icount.c (ext2fs_create_icount): Change function so that it also
1447 takes a new argument which contains a "hint" icount
1448 structure. This "hint" icount allows the create function
1449 to set up the sorted list in advance. This reduces
1450 significantly the amount of data moving needed to insert
1451 these inodes into the list later.
1452
1453 * icount.c (ext2fs_icount_validate): New function which validates
1454 that the icount structure's rep invariant.
1455
1456 * icount.c (get_icount_el): Completely revamped implementation
1457 to subsume put_icount_el(). Put_icount_el() used to
1458 use an O(N) implementation to insert in the middle
1459 of the icount list. It now uses a O(ln N) to search
1460 for where the icount should be inserted, and then uses
1461 a memcpy to move the list down (instead of a for loop).
1462
1463 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1464 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1465 to see if the inode is within bounds; if it isn't, return
1466 EINVAL.
1467
1468 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1469 when a bad inode number is passed to test_generic_bitmap
1470 to be EXT2FS_TEST_ERROR instead of the wrong
1471 EXT2FS_UNMARK_ERROR.

1480
1481Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1482
1483 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1484 ext2fs_fast_test_block_bitmap_range().
1485
1486 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1487 ext2fs_test_block_bitmap_range: New inline functions which
1488 test to see whether a contiguous range of blocks is
1489 available.
1490
1491Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1492
1493 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1494 use ext2fs_badblocks_* instead of badblocks_*
1495
1496 * bb_compat.c: New file which translates between old badblocks_*()
1497 names to ext2fs_badblocks_*()
1498
1499 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1500 link.c (since e2fsck doesn't use ext2fs_unlink()).
1501
1502 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1503 bitmap resizing routine moved from bitmaps.c, since e2fsck
1504 doesn't need to use this function.
1505
1506 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1507 since e2fsck only needs ext2fs_lookup.
1508
1509Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1510
1511 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1512 already set; this is needed so that programs like dump
1513 which use the inode scan functions will deal with
1514 filesystems that have bad blocks in the inode table.
1515
1516Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1517
1518 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1519 Moved to ext2fsP.h, since it doesn't need to be part of
1520 the public interface.
1521
1522 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1523
1524Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1525
1526 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1527 directory block list abstraction. (Code moved from
1528 e2fsck).
1529
1530 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1531 to inode.c (since no one else should be peeking inside it!)
1532
1533 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1534
1535 * openfs.c (ext2fs_open): Check the feature set in the ext2
1536 superblock, and refuse to open filesystems if they contain
1537 incompatible features. (Can be overriden with the
1538 EXT2_FLAG_FORCE
1539
1540Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1541
1542 * block.c (ext2fs_block_iterate2): Added new function
1543 ext2fs_block_iterate2 which changes the function
1544 signature of the callback function to include the
1545 referencing block and offset.
1546
1547 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1548 ext2fs_inode_scan_goto_blockgroup which allows an
1549 application to jump to a particular block group while
1550 doing an inode scan.
1551
1552Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1553
1554 * dirblock.c: Include string.h, since we use memcpy().
1555
1556Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1557
1558 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1559 a long not an int; this doesn't matter on i386 machines,
1560 but it does on Alpha's.
1561
1562Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1563
1564 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1565 table pointer is NULL, then return an error indicating
1566 that the inode table is missing.
1567 (get_next_blockgroup, get_next_blocks,
1568 ext2fs_get_next_inode): Don't treat a missing inode table
1569 as permanent error. Return MISSING_INODE_TABLE, but as an
1570 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1571
1572 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1573 ext2fs_write_inode_bitmap): If the inode or block bitmap
1574 block is zero, then don't write out the inode or block
1575 bitmap. The idea here is to avoid stomping on the
1576 superblock.
1577 (read_bitmaps): If the inode or block bitmap block is
1578 zero, then fill in that portion of the inode or block
1579 bitmap with all zeros.
1580
1581 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1582 blocks in inode table when the inode table size is
1583 non-standard (and can therefore span blocks).
1584
1585Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1586
1587 * alloc.c (ext2fs_new_block): Fix fencepost error in
1588 ext2fs_new_block; make sure we don't try to allocate the
1589 first block beyond the end of the filesystem.
1590
1591Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1592
1593 * inode.c (check_for_inode_bad_blocks): New function called by
1594 get_next_blocks() to avoid reading in bad blocks marked in
1595 fs->badblocks. Inodes located in bad blocks are returned
1596 by ext2fs_get_next_inode() returns the error code
1597 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1598
1599 * alloc_tables.c (ext2fs_allocate_tables): New function which
1600 performs the part of mke2fs's job of allocating the
1601 filesystem tables.
1602
1603 * test_io.c (test_close): IO manager which is used for testing
1604 purposes.
1605
1606Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1607
1608 * inode.c (ext2fs_get_next_inode): Separate out the function of
1609 setting up for a new block group to get_next_blockgroup().
1610 Separate out the function of reading in blocks of the
1611 inode table to get_next_blocks().
1612
1613 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1614
1615 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1616 blocks to the badblock list in sorted order. This allows
1617 badblocks_list_test to be coded using a binary search for
1618 speed.
1619
1620Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1621

1625
1626 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1627 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1628 consistency's sake.
1629
1630 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1631 set, then only write out the master superblock.
1632
1633Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1634
1635 * block.c (ext2fs_block_iterate): Fixed bug which caused
1636 block_iterate to fail to handle HURD created filesystems;
1637 it tested the inode translator field before the inode was
1638 loaded.
1639
1640Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1641
1642 * initialize.c (ext2fs_initialize): Make sure the description for
1643 the inode bitmap is set correctly.
1644
1645 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

1652
1653 * initialize.c: Override the kernel's idea of default
1654 checkinterval from 0 (never) to 180 days.
1655
1656Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1657
1658 * namei.c (ext2fs_namei_follow): New function which follows
1659 symbolic link (if any) at the target.
1660
1661Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1662
1663 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
1664 for shortcut function fs->read_inode() and fs->write_inode().

1669 superblock.
1670
1671 * namei.c (ext2fs_follow_link): New function.
1672 (ext2fs_namei): Extended to have support for chasing
1673 symbolic links. ext2fs_namei() still returns an inode
1674 which is a symbolic link. Symbolic links are only chased
1675 while resolving the containing directory. To chase
1676 symbolic links of the final result, use
1677 ext2fs_follow_link().
1678
1679Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1680
1681 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1682
1683 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1684 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

1687
1688 * initialize.c (ext2fs_initialize): On systems where the byte
1689 order is not i386 compatible, set the swap_byte flag.
1690
1691 * inode.c (inocpy_with_swap): Check to see if inode contains a
1692 fast symlink before swapping the inode block fields. This
1693 required adding a new argument to inocpy_with_swap to
1694 determine whether the mode field is in host order or not.
1695
1696Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1697
1698 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1699 the sparc, if EXT2_STD_BITOPS set, use the standard
1700 i386-compatible bitmask operations, instead on the
1701 non-standard native bitmask operators.
1702
1703Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1704
1705 * block.c (ext2fs_block_iterate): Cause block iterator to return
1706 the HURD translator block (along with everything else).
1707 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1708 iterator, then don't return any meta data blocks
1709 (including the HURD translator).
1710
1711Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1712

1715 * uuid.c: New file, containing UUID utility functions.
1716
1717Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1718
1719 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1720
1721Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1722
1723 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1724
1725Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1726
1727 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1728 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1729 that's a basic value that must be correct for the rest of
1730 the library to work.
1731
1732 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1733 code.
1734

1788 EXT2FS_CONST_ADDR.
1789
Theodore Ts'o50e1e101997-04-26 13:58:21 +00001790Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>

1845 Move these functions to freefs.c.
1846
1847 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1848 descriptors shadow memory to keep purify quiet. (This
1849 also has the nice benefit that the unused portion of the
1850 shadow descriptors are zeroed out.)
1851
1852 * dirblock.c (ext2fs_write_dir_block): We need to use
1853 dirent->rec_len *before* it's byteswapped to find the
1854 location of the next directory structure!
1855

1878 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1879 to read/write the directory block.
1880
1881 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1882 file containing functions for reading and writing
1883 directory blocks (byte swapping if necesssary)
1884
1885 * block.c (block_iterate_ind, block_iterate_dind,
1886 block_iterate_tind): Byte swap the block addresses if
1887 EXT2_SWAP_BYTES is set (and swap them back before writing
1888 them out.)
1889
1890 * inode.c (inocpy_with_swap): New function.
1891 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1892 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1893
1894 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1895 the superblock and group descriptors before writing it out.
1896
1897 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1898 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1899 and group descriptors.
1900
1901 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1902 to desp ext2 filesystem structures.
1903
1904 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1905 supplied by Pete A. Zaitcev so that the C language
1906 versions of these functions are more portable. They will
1907 now work on both little and big endian systems, and the
1908 assumption that 32-bit integers are used is gone.
1909
1910 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1911 doing byte swapping.
1912
1913 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1914 byte swapping should take place.
1915
1916Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1917
1918 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
1919 ext2fs_compare_inode_bitmap_end): Added new file
1920 containing routines to compare bitmaps.
1921
1922 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1923 Added new error codes.
1924
1925Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1926
1927 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1928 if the magic number is correct, it will be allocated.
1929
1930Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1931
1932 * block.c (block_iterate_ind, block_iterate_dind,
1933 block_iterate_tind): Don't recompute block_nr each loop;
1934 just increment it! Factor check of BLOCK_FLAG_APPEND out
1935 of the loop. Factor mask of BLOCK_CHANGED into changed
1936 variable out of the loop. (block_iterate_ind, in
1937 particular, gets called a lot, so every little
1938 optimization helps.)
1939
1940Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1941
1942 * block.c (block_iterate_ind, block_iterate_dind,
1943 block_iterate_tind): Precompute limit of loop to speed up
1944 block_iterate_ind and company.
1945
1946 * bitops.h (ext2fs_fast_mark_block_bitmap,
1947 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1948 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1949 ext2fs_fast_test_inode_bitmap): Add fast version of these
1950 functions, which don't do range checking.
1951
1952 * bitops.h (ext2fs_get_block_bitmap_start,
1953 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1954 ext2fs_get_inode_bitmap_end): Add new accessor functions
1955 which return the start and end points of the bitmaps.
1956
1957Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1958
1959 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1960 instead of llseek. The errno if the offset is too large
1961 and lseek is not supported should be EINVAL, not -EINVAL.
1962
1963Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1964
1965 * Makefile.in: Added support for ELF shared libraries.

1972
1973Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1974
1975 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1976
1977Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1978
1979 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1980
1981 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1982 the S_*, which are normally defined in <sys/stat.h>. This
1983 allows us to compile e2fsprogs on a non-Linux system,
1984 which may have a different value for S_IFDIR.
1985
1986Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1987
1988 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1989 this is a user-mode application!
1990
1991Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1992
1993 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1994 __linux__ so that non-linux systems won't see it.
1995
1996 * alloc.c: Include <errno.h> if possible.
1997 * badblocks.c: Ditto.

2010 * rw_bitmaps.c: Ditto.
2011 * unix_io.c: Ditto.
2012
2013 * Makefile.in: Rewritten to conform to GNU coding standards and
2014 support separate compilation directories.
2015
2016Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2017
2018 * initialize.c (ext2fs_initialize): Don't allow more than one
2019 bitmaps's worth of inodes in a group.
2020
Theodore Ts'of3db3561997-04-26 13:34:30 +00002021Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2022
2023 * llseek.c (ext2_llseek): Added error checking to the llseek()
2024 compat code to protect against overflow. This only
2025 applies to 1.0 and early 1.1 kernels, which don't support
2026 the llseek() system call.
2027
2028Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2029
2030 * unix_io.c (unix_open): Initialize the read_error and write_error
2031 io_channel pointers to be null.
2032
2033 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2034 found, clear it but don't try to update the filesystem
2035 accounting information, since that's hopeless anyway.
2036
2037 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2038 bloblock_iterate_tind): Check to see if the indirect blocks are
2039 valid before trying to read them.
2040
2041 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
2042 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2043
2044 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2045 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2046 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2047 illegal block or inode number is passed in, return instead
2048 of trying to test, set, or clear the bit.
2049
2050Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2051
2052 * Makefile: Added a dummy install target in case shared libraries
2053 are not built.
2054
2055Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2056
2057 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
2058 the real last block of the bitmap should be calculated.
2059
2060Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
2061
2062 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
2063 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
2064 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
2065 ext2fs_free_block_bitmap): Add magic number checking for
2066 the inode and block bitmaps.
2067
2068 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2069 magic number for a block bitmap instead of an inode bitmap.
2070
2071 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
2072 magic number checking for the inode_scan structure.
2073
2074 * badblocks.c (badblocks_list_free, badblocks_list_add,

2083 both for io_channel structure and unix_private_data
2084 structure.
2085

2087 magic number.
2088
2089 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2090 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2091 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2092 * read_bb.c (ext2fs_read_bb_inode):
2093 * read_bb_file.c (ext2fs_read_bb_FILE):
2094 * newdir.c (ext2fs_new_dir_block):
2095 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
2096 * link.c (ext2fs_link, ext2fs_unlink):
2097 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
2098 ext2fs_write_inode, ext2fs_get_blocks,
2099 ext2fs_check_directory):
2100 * get_pathname.c (ext2fs_get_pathname):
2101 * expanddir.c (ext2fs_expand_dir):
2102 * block.c (ext2fs_block_iterate):

2114 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2115 openfs.c into its own file.
2116
2117 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2118 structure magic numbers.
2119
2120 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2121 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2122 someone uses the -b option to specify the use of the backup
2123 superblock --- this usually means that the main superblock is
2124 toast. :-)
2125
2126 * ext2fs.h:
2127 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2128 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2129 revision level to the superblock.
2130
2131Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2132
2133 * ext2fs.h:
2134 * bitmaps.c:
2135 * bitops.c
2136 * bitops.h:
2137 * openfs.c:
2138 * initialize.c: Completely revamped the inode and block bitmap
2139 structures, so that they can be better chance of being extensible
2140 in a shared library. They are now their own type, instead of
2141 being a char *. Also, the function signatures of
2142 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2143 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2144 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2145 changed to eliminate the ext2_filsys argument, since it is no
2146 longer necessary.
2147
2148Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2149
2150 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2151 system call if available.
2152
2153 * llseek.c: new file. This is the stub calling the llseek system
2154 call which allows supports for 2GB+ file systems.
2155
2156 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2157 the creator operating system.
2158
2159Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2160
2161 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2162 the group descriptor statistics in addition to everything else.
2163 This relieves mke2fs of the responsibility of doing it.
2164
2165 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2166 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2167 not the generic C function equivalents should be included or not.
2168
2169 * openfs.c (ext2fs_open): If a superblock is specified, then use
2170 the backup group descriptors that go along with this superblock,
2171 instead of using the primary group descriptors. This allows
2172 e2fsck to recover filesystems where the primary group descriptors
2173 have been trashed.
2174
2175
