1 2001-09-16 Theodore Tso <tytso@valinux.com>
3 * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h>
4 which was breaking the build on the Hurd. (Addresses
7 2001-09-02 Theodore Tso <tytso@thunk.org>
9 * Release of E2fsprogs 1.24a
11 2001-08-30 Theodore Tso <tytso@thunk.org>
13 * Release of E2fsprogs 1.24
15 2001-08-30 Theodore Tso <tytso@valinux.com>
17 * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64
18 changes, since the ioctl number has been reused by another
21 2001-08-15 Theodore Tso <tytso@valinux.com>
23 * Release of E2fsprogs 1.23
25 2001-08-05 Theodore Tso <tytso@valinux.com>
27 * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast
28 version of the bitmap test routines to speed up these
29 routines. (At some point I may want to make these
30 routines use the find_first_bit functions, but that will
31 add a lot of complexity since it means that these
32 functions will have to break the bitmap abstraction
33 boundary. It's not clear it's worth it.)
35 * mkjournal.c (mkjournal_proc): Remember the last block allocated
36 to speed up ext2fs_new_block().
38 2001-07-29 Theodore Tso <tytso@valinux.com>
40 * finddev.c (scan_dir): Fix memory leak; we weren't calling
41 closedir() when exiting the function in all cases.
43 2001-07-27 Theodore Tso <tytso@valinux.com>
45 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
46 block usable in the journal for external journals to be 2
47 or 3, depending on the blocksize, so that the existing
48 kernel code does the right thing.
50 * getsize.c (ext2fs_get_device_size): Add support for the
51 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
52 from Ben LaHaise, but it's likely this interface won't
55 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
56 when writing the journal superblock, too. (Oops! Needed
57 to make 1k filesystems with external journal to work.)
59 2001-07-26 Theodore Tso <tytso@valinux.com>
61 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
62 to find the journal superblock if the blocksize is 1024.
64 2001-07-21 Theodore Tso <tytso@valinux.com>
66 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
68 2001-07-20 Theodore Tso <tytso@valinux.com>
70 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
71 attribute block, set the filesystem changed bit.
73 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
74 Comment out these functions since we're not using them.
76 2001-07-10 Theodore Tso <tytso@valinux.com>
78 * closefs.c (write_primary_superblock): After writing changes to
79 the primary superblock, update the original superblock
80 copy so we don't have to re-write those changes in the
82 (ext2fs_flush): Clear the superblock dirty flag after
83 we've flushed out changes to disk.
85 2001-07-07 Theodore Tso <tytso@valinux.com>
87 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
88 to avoid register conflicts when compiling in PIC mode.
90 2001-07-04 Theodore Tso <tytso@valinux.com>
92 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
93 Add new functions (C and in i386 assembler) which quickly
94 find bits set in a bitmask.
96 2001-06-23 Theodore Tso <tytso@valinux.com>
98 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
99 ext2_ext_attr.h and ext_attr.c for extended attributes
102 * Release of E2fsprogs 1.22
104 2001-06-22 Theodore Tso <tytso@valinux.com>
106 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
107 descriptor so that adding a journal to a mounted
108 filesystem doesn't die. (Fixes a bug accidentally
109 introduced in e2fsprogs 1.21.)
111 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
112 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
113 fchflags without defining UF_NODUMP. (Addresses Debian
116 * flushb.c: Use platform independent method of defining the
117 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
118 since on newer glibc's BLKFLSBUF is defined there.
120 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
121 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
122 to support byte swapping even if we don't support the
123 conversion functions. (Fixes Debian bug #101686).
125 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
126 since the byte-swapping code all assumes the
127 ext2_dir_entry structure. (It's a question of whether or
128 not name_len should be byte-swapped or not, and whether
129 it's a 16 bit or 8 bit field.)
131 2001-06-15 Theodore Tso <tytso@valinux.com>
133 * Release of E2fsprogs 1.21
135 2001-06-15 Theodore Tso <tytso@valinux.com>
137 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
138 file which is generated and is therefore found in the
139 build directory, not source directory.
141 * ismounted.c (check_mntent_file): Use a test file in / to check
142 to see if the root filesystem is mounted read-only. This
143 protects against the case where /etc might not be on /, as
144 well as the case where /etc/mtab doesn't exist. (Both are
145 should-never happen scenarios, but you never know...)
147 2001-06-14 Theodore Tso <tytso@valinux.com>
149 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
150 Remove unneeded #pragma argsused, since the arguments are
153 2001-06-13 Theodore Tso <tytso@valinux.com>
155 * ext2_types.h.in: If linux/types.h has been defined, then don't
156 try to redefine the typedefs.
158 * Makefile.in (HFILES): Add ext2_types.h to the list of files
159 which should be installed.
161 * ismounted.c (check_mntent_file): Work around GNU hurd brain
162 damage. Addresses Debian bug #100304.
164 * Makefile.in: Limit some .o files from being included into the
165 library if --disable-debugfs, --disable-swapfs,
166 --disable-imager, or --disable-resizer are used.
168 2001-06-12 Theodore Tso <tytso@valinux.com>
170 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
171 function, and use the ext2fs_badblocks_* functions
174 2001-06-11 Theodore Tso <tytso@valinux.com>
176 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
177 ext2fs_mark_generic_bitmap and
178 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
179 functions. (This saves space and doesn't significantly
180 change the speed of e2fsck on a P-III.)
182 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
183 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
184 include the byte-swapping logic if ENABLE_SWAPFS is turned
185 on or if we're on a big-endian machine.
187 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
188 set EXT2_FLAG_SWAP_BYTES, instead of using
191 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
192 autoconf to determine whether or not return
193 EXT2_FLAG_SWAP_BYTES.
195 2001-06-10 Theodore Tso <tytso@valinux.com>
197 * Makefile.in: Remove the dependence on the libe2p library.
199 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
200 with direct usage of the ioctl/fchflags so that we don't
201 have to depend on the libe2p library.
203 2001-06-08 Theodore Tso <tytso@valinux.com>
205 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
206 when trying to find a 32-bit wide type.
208 * icount.c (insert_icount_el): Fix the code used to estimate the
209 size of the new icount array to be more intelligent, to
210 avoid reallocating the array too many times. Thanks to
211 Enrique Perez-Terron for pointing this out.
213 2001-06-02 Theodore Tso <tytso@valinux.com>
215 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
216 for a symlink to determine whether it is a fast symlink.
218 2001-06-01 Theodore Tso <tytso@valinux.com>
220 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
221 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
223 2001-05-25 Theodore Tso <tytso@valinux.com>
225 * Release of E2fsprogs 1.20
227 2001-05-25 Theodore Tso <tytso@valinux.com>
229 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
230 some to clean up Andreas's patches. Use strncpy instead
231 of strcpy to save the root's mountpoint. Clean up #ifdef
232 structure. Remove uneeded variable in testing/debug driver.
234 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
236 * ismounted.c: Add check for root device which doesn't depend on
237 /etc/fstab or /proc/mounts to be correct. Don't call
238 endmntent() before we are done with mnt struct.
240 2001-05-23 Theodore Tso <tytso@valinux.com>
242 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
245 2001-05-21 Theodore Tso <tytso@valinux.com>
247 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
248 make room for pre-existing usage of
249 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
250 the same codepoint as EXT2_BTREE_FL.
252 2001-05-20 Theodore Tso <tytso@valinux.com>
254 * ext2fs.h: #include <> instead of "" for ext2fs and et header
255 files, since they will be installed in /usr/include
257 2001-05-14 Theodore Tso <tytso@valinux.com>
259 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
260 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
261 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
262 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,

270 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
271 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
272 Adjust all files in this directroy to include this file.
274 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
277 2001-05-05 Theodore Tso <tytso@valinux.com>
279 * fileio.c (ext2fs_file_read): Factored out common code and
280 cleaned up function. Fixed a bug where if there was an
281 error reading from the disk, the number of bytes read
282 wasn't reliably set. (Fixes Debian bug #79163)
283 (ext2fs_file_write): Factored out common code and made
284 function more efficient; if writing a full block, don't
285 bother to do a read-modify-write cycle.
287 2001-05-04 Theodore Tso <tytso@valinux.com>
289 * dirblock.c (ext2fs_read_dir_block): Check for an directory
290 record length which isn't a multiple four, and treat that
291 as an invalid. Scan the directory and return an error
292 (EXT2_ET_DIR_CORRUPTED) if the directory records are
294 (ext2fs_write_dir_block): If while byte-swapping the
295 directory block, if there's an error, abort and return
296 EXT2_ET_DIR_CORRUPTED.
298 2001-05-02 Theodore Tso <tytso@valinux.com>
300 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
301 image_header field in the ext2_filsys structure
303 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
304 * inode.c (ext2fs_read_inode):
305 * rw_bitmaps.c (read_bitmaps):
306 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
308 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
309 sure the full bitmap is saved.
311 2001-05-01 Theodore Tso <tytso@valinux.com>
313 * e2image.h (struct ext2_image_hdr): Add space for the device name
316 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
317 make sure the rec_len is a multiple of 4, to prevent
318 bus-errors on architectures which care about mis-aligned
321 2001-04-25 Theodore Tso <tytso@valinux.com>
323 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
324 query the device sizes using the BLKGETSIZE ioctl.
326 2001-04-16 Theodore Tso <tytso@valinux.com>
328 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
329 before checking /etc/mtab. The EXT2_MF_READONLY flag is
330 now set from the /etc/mtab options field for all
331 filesystems, not just the root filesystem. Add debugging
332 code to make it easier to test ext2fs_check_if_mounted().
334 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
335 check; return an error if there's an attempt to create a
336 journal less than 1024 filesystem blocks.
338 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
339 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
341 2001-02-20 Theodore Tso <tytso@valinux.com>
343 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
346 * tst_byteswap.c: New function to test the byteswap functions.
347 Add to regression test suite.
349 2001-02-08 Theodore Tso <tytso@valinux.com>
351 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
353 2001-02-07 Theodore Tso <tytso@valinux.com>
355 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
356 of s_first for external devices to always be 1, since
357 jsb->s_first is always relative to the start of the
358 journal superblock. Use htonl(1) when setting s_nr_users.
360 2001-01-17 Theodore Ts'o <tytso@valinux.com>
362 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
363 device number of the filesystem (instead of the journal)
364 was being dropped into s_journal_dev.
366 2001-01-15 Theodore Ts'o <tytso@valinux.com>
368 * initialize.c (ext2fs_initialize): Add support for initializing
369 the ext2 superblock for external journal devices. This
370 basically means we don't bother to allocate any block
373 * openfs.c (ext2fs_open): Only open external journal devices if
374 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
375 ext2fs_open. When opening such devices, don't try to read
376 the block group descriptors, since they're not there.
378 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
380 * mkjournal.c: Export a new function,
381 ext2fs_create_journal_superblock(), which allocates and
382 returns a buffer containing a journal superblock. This is
383 needed by mke2fs to create an external journal. Rewrote
384 ext2fs_add_journal_device() so that it no longer creates
385 the external journal, but rather adds a filesystem to an
386 existing external journal. It handles all of the UUID
389 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
390 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
391 Changed function prototype for ext2fs_add_journal_device().
393 2001-01-14 Theodore Ts'o <tytso@valinux.com>
395 * closefs.c (ext2fs_flush): Don't write out anything beyond the
396 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
399 2001-01-12 Theodore Ts'o <tytso@valinux.com>
401 * imager.c: Fix gcc -Wall complaints and a series of bugs where
402 retval wasn't set correctly. (Thanks to Andreas Dilger
403 for pointing this out.)
405 2001-01-11 <tytso@snap.thunk.org>
407 * flushb.c (ext2fs_sync_device): New function which centralizes
408 all of the places which might try to use the BLKFLSBUF
409 or FDFLUSH ioctls (and usually failing to define them
410 since the system header files don't usually do this for
411 us, and we're trying to avoid usage of kernel include
414 2001-01-10 <tytso@snap.thunk.org>
416 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
417 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
418 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
419 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
420 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
421 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
422 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
423 ext2_ino_t, to protect applications that attempt to
424 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
425 changes ino_t(!?). So we use ext2_ino_t to avoid an
426 unexpected ABI change.
428 2001-01-05 <tytso@snap.thunk.org>
430 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
431 we may overrun allocated memory in case of a corrupted
432 filesystem (or an e2fsck test case :-) when byte-swapping
435 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
437 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
438 complaints including a missing return 0 at the end of
439 ext2fs_add_journal_device.
441 2001-01-03 <tytso@snap.thunk.org>
443 * Makefile.in: Link in libe2p when creating libext2fs as a shared
444 library, since mkjournal.c now references fsetflags().
446 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
447 Dilger's changes (with fixups) to allow on-line creation
450 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
451 EXT2_FLAG_SUPER_ONLY, which the close routines to only
452 update the superblock, and not the group descriptors.
454 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
456 * ismounted.c: add ext2fs_check_mount_point() function, which will
457 optionally return the mount point of a device if mounted
459 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
461 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
462 ext2fs_add_journal_inode()
464 2001-01-01 <tytso@snap.thunk.org>
466 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
467 source (but not binary) compatibility of some users of the
468 ext2 library. They should just simply do a global search
469 and replace of struct ext2fs_sb with struct
470 ext2_super_block, and use their own private copy of
471 ext2_fs.h if they aren't already.
473 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
474 Replace use of ext2fs_sb with ext2_super_block.
476 2000-12-31 <tytso@snap.thunk.org>
478 * ext2fs.h: Cleaned up header file by removing definitions of
479 feature flags that might not have been defined in older
480 ext2 header files. Now that we're using our own
481 include/linux/ext2fs.h header file, this can never happen.
483 * jfs_dat.h: Removed old header file which is no longer needed.
485 2000-12-13 Theodore Ts'o <tytso@valinux.com>
487 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
488 by Andreas Dilger to update the filesystem revision to
491 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
494 2000-12-09 <tytso@snap.thunk.org>
496 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
497 ext2fs_add_journal_device): Add a new argument to the APIs
498 of these function, which is a flags word. This is used to
499 allow the creation of a V1 superblock for those folks who
500 are using ext3 0.3b in production. Note, the user-land
501 interface for getting at this flag won't be documented, as
502 the V1 superblock is deprecated.
504 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
505 which creates a V2 superblock instead of a V1 superblock.
507 2000-11-21 <tytso@snap.thunk.org>
509 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
510 out by Andreas Dilger.
512 2000-11-05 <tytso@snap.thunk.org>
514 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
515 ext2_fs.h, Makefile.in: New file that has routines that
516 save ext2fs metadata to a file.
518 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
520 * e2image.h: New file which defines the file format for the ext2
521 image file. (Saved copy of ext2 metadata to a file as a
522 saving throw against worst-case damage.)
524 2000-11-01 <tytso@snap.thunk.org>
526 * inode.c (ext2fs_flush_icache): Add new function
527 ext2fs_flush_icache() which flushes the internal inode
528 cache. Applications which modify the inode table blocks
529 directly must call this function.
531 2000-10-26 <tytso@snap.thunk.org>
533 * mkjournal.c: Add #include of netinet/in.h, since Solaris
534 requires it for ntohl().
536 * ext2_io.h (io_channel_write_byte): Add new interface to allow
537 callers to write specific byte ranges. This is an
538 optional interface, which not all IO channels may
541 * unix_io.c (unix_write_byte):
542 * test_io.c (test_write_byte): Add implementation of the
545 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
546 function which writes the primary superblock. If the IO
547 channel supports writing raw bytes directly, only fields
548 which were modified are written to the disk. This makes
549 it safe(r) to use utilities like tune2fs on a mounted
552 * freefs.c (ext2fs_free): Free the original superblock if it is
555 * openfs.c (ext2fs_open): Store a copy of the original superblock
558 * ext2fs.h: Add a field to store the original superblock in the
559 ext2 context structure.
561 2000-10-24 <tytso@snap.thunk.org>
563 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
564 don't need to use llseek).
566 2000-10-24 <tytso@valinux.com>
568 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
569 creating an ext3 journal on a filesystem.
571 2000-08-21 <tytso@valinux.com>
573 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
575 2000-08-22 <tytso@valinux.com>
577 * unix_io.c: Make massive changes to support a multiple block
578 writethrough cacheing.
580 * ext2_io.h: Added flags field to the io_channel structure.
582 2000-08-19 <tytso@valinux.com>
584 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
585 provides the function ext2fs_find_block_device(). This
586 function returns the pathname to a block device, given its
589 2000-07-13 <tytso@valinux.com>
591 * Release of E2fsprogs 1.19
593 2000-07-07 Theodore Ts'o <tytso@valinux.com>
595 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
596 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
597 list of filesystem flags supported by the library.
599 2000-07-04 Theodore Ts'o <tytso@valinux.com>
601 * ext2fs.h: Update to include latest journalling additions to the
604 * dll/jump.funcs: Add new jumptable entries for
605 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
606 ext2fs_badblocks_equal.
608 * tst_badblocks.c: Update test program to test
609 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
611 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
612 writes out bad blocks list to a file.
614 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
615 changes the callback function to take two additional
616 arguments; a private blind pointer supplied by the caller,
617 and pointer to a char * containing a pointer to the
620 * badblocks.c (ext2fs_badblocks_equal): Add new function which
621 returns true if two badblocks list are equal.
623 * Makefile.in: Remove explicit link of -lc in the shared library.
624 (It shouldn't be necessary, and is harmful in some cases).
626 2000-06-10 Theodore Ts'o <tytso@valinux.com>
628 * getsize.c (main): Add debugging code under #ifdef DEBUG
630 2000-05-27 Theodore Ts'o <tytso@valinux.com>
632 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
633 earlier, so that if there's an error reading it, we can
634 more cleanly back out of the operation.
636 2000-05-25 <tytso@snap.thunk.org>
638 * getsize.c (ext2fs_get_device_size): Use open64() instead of
639 open() if it exists. Under linux, manually define the
640 ioctl for BLKGETSIZE if it isn't already defined and it's
643 * unix_io.c (unix_open): Use open64() instead of open() if it
646 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
647 available (and prototypes are defined) use it in
648 preference to llseek.
650 * Makefile: Add hack dependency rule so that parallel makes work
653 2000-05-18 Theodore Ts'o <tytso@valinux.com>
655 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
657 2000-04-03 Theodore Ts'o <tytso@valinux.com>
659 * block.c: Readibility tweak in conditionals involving
662 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
663 how to define __s64 and __u64. Turn off "compression is
664 experimental" warning if the cpp macro
665 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
667 2000-02-11 <tytso@snap.thunk.org>
669 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
670 Conditionally include Compression as a supported type if
671 ENABLE_COMPRESSION (via --enable-compression) is turned on.
673 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
675 2000-02-08 <tytso@snap.thunk.org>
677 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
678 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
679 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
680 Change to return the previous state of the bit that is
681 being marked or unmarked. For speed optimization.
683 2000-02-02 Theodore Ts'o <tytso@valinux.com>
685 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
687 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
688 needed any more; we know it will always be i_generation.
689 Add support for swapping the high bits of the uid and gid.
691 1999-11-19 <tytso@valinux.com>
693 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
694 counts if the link was successful. Patch suggested by
697 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
698 the source directory.
700 1999-11-10 <tytso@valinux.com>
702 * Release of E2fsprogs 1.18
704 1999-11-08 <tytso@valinux.com>
706 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
707 since ext2fs_badblocks_list_free was moved to freefs.c.
709 * tst_badblocks.c: Use the newer badblocks API names. Add
710 duplicate blocks to the test inputs to test dealing with
711 adding blocks which are already in the badblocks list.
713 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
714 of the list, use a shortcut O(1) operations instead of an
715 O(n) operation. (Idea suggested by David Beattie.)
717 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
718 of badblocks_list_free(), to save a procedure call.
720 1999-10-26 <tytso@valinux.com>
722 * Release of E2fsprogs 1.17
724 1999-10-26 <tytso@valinux.com>
726 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
727 seem to handle ~0UL the same way as they used to.
729 1999-10-25 <tytso@valinux.com>
731 * nt_io.c (_OpenNtName): Open the device using
732 FILE_SYNCHRONOUS_IO_NONALERT instead of
733 FILE_SYNCHRONOUS_IO_ALERT
734 (nt_open): At the end of the device open routine, unlock
735 the drive but do not dismount it.
737 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
740 1999-10-22 <tytso@valinux.com>
742 * Release of E2fsprogs 1.16
744 1999-10-22 <tytso@valinux.com>
746 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
748 * link.c (ext2fs_link): This call now uses the low three bits of
749 the flags parameter to pass the directory filetype
750 information; it will set the directory entry FILETYPE
751 information if the filesystem supports it.
753 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
754 option is set, then create the '.' and '..' entries with
755 the filetype set to EXT2_FT_DIR.
757 1999-09-24 <tytso@valinux.com>
759 * nt_io.c: New file which supports I/O under Windows NT.
761 1999-09-07 <tytso@valinux.com>
763 * ext2fs.h: Add new fields for journalling and define new
764 feature bits used by newer filesystems: IMAGIC_INODES,
765 HAS_JOURNAL, RECOVER.
767 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
768 we update the inode block count and size files so that the
769 block count field is updated correctly when we create an
772 1999-07-18 Theodore Ts'o <tytso@valinux.com>
774 * Release of E2fsprogs 1.15
776 1999-06-23 <tytso@valinux.com>
778 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
779 kernels that use i_generation instead of i_version. Patch
780 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
782 1999-06-21 <tytso@valinux.com>
784 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
785 directory entry before calling the callback function.
786 This should prevent some core dumps of insufficiently
787 paranoid callback functions.
789 1999-05-29 <tytso@rsts-11.mit.edu>
791 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
793 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
794 that we don't handle writing yet (we do). Fixed bug where
795 we weren't allocating a big enough buffer for ext2_bmap.
797 1999-05-03 <tytso@rsts-11.mit.edu>
799 * openfs.c (ext2fs_open): Check to make sure that the number of
800 blocks per group is not zero --- if so, it must be a bad
803 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
805 * Release of E2fsprogs 1.14
807 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
809 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
810 the inode number is zero; if it's zero, return
811 EXT2_ET_BAD_INODE_NUM.
813 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
815 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
816 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
819 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
821 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
822 non-Linux case to use EINVAL by default, unless it isn't
823 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
826 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
828 * Release of E2fsprogs 1.13
830 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
832 * Makefile.in: Updated dependencies.
834 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
836 * initialize.c (ext2fs_initialize): Make sure that we allocate
837 enough inodes so that we can make a valid filesystem.
839 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
841 * rw_bitmaps.c: Fixed signed/unsigned warnings.
843 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
844 function declaration.
846 * dblist.c (make_dblist): Add safety check in case the dblist
847 pointer passed in is null (in which case, assign it to
848 fs->dblist). Fixed some signed/unsigned warnings.
850 * bmap.c: Make addr_per_block be of type blk_t to avoid
851 signed/unsigned warnings.
853 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
854 function declaration.
856 * get_pathname.c (get_pathname_proc): Use return value from
857 ext2fs_get_mem, instead of checking if &gp->name is

861 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
862 from the function declaration.
864 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
865 return the error directly instead of jumping to the
866 cleanup routine, since we don't need to do any cleanup.
868 * alloc_table.c (ext2fs_allocate_group_table): Make this
869 function take a dgrp_t for its group argument.
871 * ext2fs.h: Make dgrp_t an __u32 type, and make
872 fs->desc_group_count be of type dgrp_t.
874 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
876 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
877 than 10 blocks when we need to expand the size of the
880 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
882 * Release of E2fsprogs 1.12
884 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
886 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
887 appropriate for all of the block group copies, so that
888 it's clear where the beginning of the filesystem is on the
889 disk. (For when the partition table gets scrod.)
891 * ext2fs.h: Change the name of the feature from
892 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
893 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
895 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
897 * inode.c (get_next_blockgroup): Fix bug where if
898 get_next_blockgroup() is called early because of a missing
899 inode table in a block group, the current_inode counter
900 wasn't incremented correctly.
902 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
904 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
905 against a completely trashed bad block inode.
907 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
909 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
910 the stride length hits a bad value, we retry the block
911 allocation starting at the beginning of the block group.
913 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
914 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
915 e2_blkcnt_t to avoid collision with LFS API.
917 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
919 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
920 way that avoids overflows on disk sizes greater than 4GB.
922 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
924 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
925 return type for comparison functions for qsort.
927 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
930 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
932 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
935 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
936 evade a potential problem with glibc's header files trying
937 to spike out linux/types.h.
939 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
940 include the old size of the memory, which is needed for
941 some braindamaged memory allocation systems that don't
944 * badblocks.c (ext2fs_badblocks_list_add):
945 bb_inode.c (clear_bad_block_proc):
946 dblist.c (ext2fs_add_dir_block):
947 icount.c (insert_icount_el):
949 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
950 pass the old size of the memory to be resized to
953 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
955 * Makefile.in: Change to use new installation directory variables
956 convention. Fix uninstall rules to take $(DESTDIR) into
959 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
961 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
962 with 32 bit longs, then we need to manually define __s64
963 and __u64, since the current kernel header files don't
964 define these if __STRICT_ANSI__ is defined. This is a
965 problem if we are compiling with full GCC warnings, since
966 we do need 64 bit support.
968 * Makefile.in (OBJS): Remove bmove.o from files to be built,
969 since we're not using ext2fs_move_blocks() and there
970 is some question as to its usefulness in its current
973 * bmap.c (block_bmap): Remove unused function.
975 * bmove.c (process_block): Fix -Wall warning.
977 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
979 * block.c (ext2fs_block_iterate3): Make the ref_offset field
980 contain the offset into the inode.i_blocks array when
981 ref_block is zero. Since we haven't done a formal
982 release of e2fsprogs since block_iterate2 was first
983 introduced, I removed block_iterate2, and renamed
984 block_iterate3 to be block_iterate2.
986 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
987 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
988 use of block_iterate and block_iterate2 to
989 block_iterate2 with the new prototype for the
990 interator function. (using blkcnt_t forr blockcount)
992 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
994 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
995 s_prealloc_blocks, s_prealloc_dir_blocks). Added
996 conditional defines of new features COMPAT_DIR_PREALLOC,
997 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
998 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
999 the library to declare that we support COMPAT_DIR_PREALLOC,
1000 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
1002 * fileio.c: Rename function ext2fs_file_llseek to be
1003 ext2fs_file_lseek, which is more accurate.
1005 * block.c: Add new function ext2fs_block_iterate3 which calls
1006 the iterator function with the blockcount argument of
1007 type blkcnt_t. This version of the function is
1008 allowed to handle large files; the other fucntions are
1011 * ext2fs.h: Add new type blkcnt_t
1013 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
1015 * block.c (ext2fs_block_iterate2): Fix bug where the block count
1016 field wasn't getting correctly incremented for sparse
1017 files when the indirect or doubly-indirect block
1018 specified in the inode was zero.
1020 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1022 * unlink.c (unlink_proc):
1023 * lookup.c (lookup_proc):
1024 * link.c (link_proc):
1025 * get_pathname.c (get_pathname_proc):
1026 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
1027 from dirent->name_len, so it can be used for other
1030 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
1031 and indicate that we have support for this incompatible
1034 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1036 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
1038 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1040 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
1041 number of directories when the block group information is
1044 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1046 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1047 inode table is missing so that we catch the case where the
1048 first block group is missing.
1050 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1053 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1055 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1057 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1059 * test_io.c (test_flush): Add a debugging printf when the flush
1062 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1063 read in, return right away.
1065 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1067 * bitops.h: Don't try to do i386 inline asm functions if the
1070 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1071 instead of linux/types.h, and e2_bitops.h instead of
1074 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1077 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1079 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1080 so that we don't need to call get_next_blockgroup() the
1081 first time around. Saves a bit of time, and prevents us
1082 from needing to assign -1 to current_group (which is an
1085 * icount.c (insert_icount_el): Cast the estimated number of inodes
1086 from a float to an ino_t.
1088 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
1089 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

1103 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1104 all assignments from void * to be compatible with C++.

1125 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1127 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1128 paranoid about validating the directory counts from the
1129 block group information.
1131 * all files: Don't include stdlib.h anymore; include it in
1132 ext2_fs.h, since that file requires stdlib.h
1134 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1136 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1137 bitmap is loaded, and return an error if it is not.
1138 (expand_dir_proc): Only use ext2fs_write_dir_block when

1168 * [all files, basically]: Added definition of ext2fs_get_mem,
1169 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1170 changed all library routines to use these wrapper functions.

1188 physical block number.
1190 * fileio.c: New file which implements simple file reading and
1193 * alloc.c (ext2fs_alloc_block): New function which allocates a
1194 block, zeros it, and updates the filesystem accounting

1199 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
1200 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
1201 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY

1204 EINVAL, ENOENT, etc.
1206 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1208 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we

1213 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1215 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H

1253 * io.h: Change the prototype of ext2fs_llseek() to use int's
1254 instead of unsigned int's.
1256 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1257 to make life easer for GNU Libc 2.
1259 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1260 filesystem has its bitmaps stored as 32-bit words with bit
1261 0 as the LSB of each word. Thus a bitmap with only bit 0
1262 set would be, as a string of bytes, 00 00 00 01 00 ... To
1263 cope with this, we byte-reverse each word of a bitmap if
1264 we have a big-endian filesystem, that is, if we are *not*
1265 byte-swapping other word-sized numbers.

1334 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1336 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1337 is zero, then return EXT2_IO_LLSEEK_FAILED.
1339 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1341 * Release of E2fsprogs 1.11
1343 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1345 * dblist.c (ext2fs_dblist_count): Added new function which returns
1346 the number of directory blocks in dblist.
1348 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1350 * unix_io.c (unix_flush): Make the io_channel flush function do a
1351 fsync to flush the kernel buffers to disk.
1353 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1355 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1356 current inode number wasn't being set by the
1357 goto_blockgroup function.
1359 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1361 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1362 of blocks which need to be moved, and moves those blocks
1363 to another location in the filesystem.
1365 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1366 bitmap, make sure all of the new parts of the bitmap are
1369 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1371 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1372 wasn't being returned to the caller.
1374 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1375 ext2fs_allocate_group_table() which sets the group tables
1376 for a particular block group. The relevant code was
1377 factored out of ext2fs_allocate_tables().
1379 * dblist.c (make_dblist): Adjust the initial size of the directory
1380 block list to be a bit more realistic (ten plus twice the
1381 number of directories in the filesystem).
1383 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1385 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1386 ext2fs_badblocks_list_test would test the list (and exceed
1387 array boundaries) if there were no bad blocks on the bad
1388 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1390 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1392 * Release of E2fsprogs version 1.10
1394 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1396 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1397 inode and block bitmaps based on the RAID 0 stride
1398 parameter (which is passed by mke2fs).
1400 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1401 mke2fs to communicate the stride length to
1402 ext2fs_allocate_tables()
1404 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1406 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1407 systems. (We can't assume that the new filesystem types
1410 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1412 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1413 allocate the inode and block bitmaps inside block group at
1416 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1418 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1419 filesystem has no free blocks, ext2fs_new_block would loop
1422 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1424 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1425 free if refcount goes to zero.

1429 * ext2fsP.h: Added refcount to ext2_inode_cache
1431 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
1434 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1435 badblocks structure.
1437 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1439 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
1441 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1443 (unix_close, test_close): Decrement the refcount and only
1444 close the io_channel if the refcount goes to 0.
1446 * io.h: Add refcount to the io_channel structure. Add new macro
1447 interface io_channel_bumpcount() to bump the refcount.
1449 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1451 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1452 cache in the filesystem handle, instead of the inode cache
1453 in a static variable.

1467 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1469 * Release of E2fsprogs version 1.09
1471 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1473 * version.c (ext2fs_parse_version_string): Check the passed in
1474 version string (instead of the hard-coded one).
1476 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1477 greater filesystem size, clamp it to prevent allocating a
1478 block or inode bitmap beyond the filesystem.
1480 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1481 overhead calculation was accidentally removed.
1483 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1485 * Release of E2fsprogs version 1.08
1487 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1490 block of a dblist entry, given the directory inode and
1493 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1495 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1496 inode bitmaps at staggered locations across the block
1497 groups, to avoid concentrating the bitmaps on a small
1498 number of disks when using striped RAID arrays.
1500 * initialize.c (ext2fs_initialize): By default, choose the maximum
1501 possible number of blocks per group (based on the size of
1502 the bitmaps in the blocksize).
1504 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1506 * initialize.c (ext2fs_initialize): Add support for
1507 EXT2_COMPAT_SPARSE_SUPER feature.
1509 * closefs.c (ext2fs_bg_has_super): New function to determine
1510 whether or a particular block group should have a
1511 superblock and block group descriptor. Used for the
1512 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1513 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1514 or not the superblock should be written out for the block
1517 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1518 for sparse duplicate superblocks.
1520 * version.c (ext2fs_get_library_version): New function which
1521 returns the library version.
1523 * version.c (ext2fs_parse_version_string): New function which
1524 parses a version string and returns a version number,
1525 so application programs can compare version numbers as
1528 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1530 * icount.c (ext2fs_create_icount): Change function so that it also
1531 takes a new argument which contains a "hint" icount
1532 structure. This "hint" icount allows the create function
1533 to set up the sorted list in advance. This reduces
1534 significantly the amount of data moving needed to insert
1535 these inodes into the list later.
1537 * icount.c (ext2fs_icount_validate): New function which validates
1538 that the icount structure's rep invariant.
1540 * icount.c (get_icount_el): Completely revamped implementation
1541 to subsume put_icount_el(). Put_icount_el() used to
1542 use an O(N) implementation to insert in the middle
1543 of the icount list. It now uses a O(ln N) to search
1544 for where the icount should be inserted, and then uses
1545 a memcpy to move the list down (instead of a for loop).
1547 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1548 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1549 to see if the inode is within bounds; if it isn't, return
1552 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1553 when a bad inode number is passed to test_generic_bitmap
1554 to be EXT2FS_TEST_ERROR instead of the wrong
1555 EXT2FS_UNMARK_ERROR.
1557 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1559 * Release of E2fsprogs version 1.07
1561 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1563 * Makefile.in (ELF_VERSION): Change version to be 2.2
1565 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1567 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1568 ext2fs_fast_test_block_bitmap_range().
1570 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1571 ext2fs_test_block_bitmap_range: New inline functions which
1572 test to see whether a contiguous range of blocks is
1575 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1577 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1578 use ext2fs_badblocks_* instead of badblocks_*
1580 * bb_compat.c: New file which translates between old badblocks_*()
1581 names to ext2fs_badblocks_*()
1583 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1584 link.c (since e2fsck doesn't use ext2fs_unlink()).
1586 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1587 bitmap resizing routine moved from bitmaps.c, since e2fsck
1588 doesn't need to use this function.
1590 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1591 since e2fsck only needs ext2fs_lookup.
1593 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1595 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1596 already set; this is needed so that programs like dump
1597 which use the inode scan functions will deal with
1598 filesystems that have bad blocks in the inode table.
1600 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1602 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1603 Moved to ext2fsP.h, since it doesn't need to be part of
1604 the public interface.
1606 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1608 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1610 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1611 directory block list abstraction. (Code moved from
1614 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1615 to inode.c (since no one else should be peeking inside it!)
1617 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1619 * openfs.c (ext2fs_open): Check the feature set in the ext2
1620 superblock, and refuse to open filesystems if they contain
1621 incompatible features. (Can be overriden with the
1624 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1626 * block.c (ext2fs_block_iterate2): Added new function
1627 ext2fs_block_iterate2 which changes the function
1628 signature of the callback function to include the
1629 referencing block and offset.
1631 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1632 ext2fs_inode_scan_goto_blockgroup which allows an
1633 application to jump to a particular block group while
1634 doing an inode scan.
1636 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1638 * dirblock.c: Include string.h, since we use memcpy().
1640 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1642 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1643 a long not an int; this doesn't matter on i386 machines,
1644 but it does on Alpha's.
1646 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1648 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1649 table pointer is NULL, then return an error indicating
1650 that the inode table is missing.
1651 (get_next_blockgroup, get_next_blocks,
1652 ext2fs_get_next_inode): Don't treat a missing inode table
1653 as permanent error. Return MISSING_INODE_TABLE, but as an
1654 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1656 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1657 ext2fs_write_inode_bitmap): If the inode or block bitmap
1658 block is zero, then don't write out the inode or block
1659 bitmap. The idea here is to avoid stomping on the
1661 (read_bitmaps): If the inode or block bitmap block is
1662 zero, then fill in that portion of the inode or block
1663 bitmap with all zeros.
1665 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1666 blocks in inode table when the inode table size is
1667 non-standard (and can therefore span blocks).
1669 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1671 * alloc.c (ext2fs_new_block): Fix fencepost error in
1672 ext2fs_new_block; make sure we don't try to allocate the
1673 first block beyond the end of the filesystem.
1675 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1677 * inode.c (check_for_inode_bad_blocks): New function called by
1678 get_next_blocks() to avoid reading in bad blocks marked in
1679 fs->badblocks. Inodes located in bad blocks are returned
1680 by ext2fs_get_next_inode() returns the error code
1681 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1683 * alloc_tables.c (ext2fs_allocate_tables): New function which
1684 performs the part of mke2fs's job of allocating the
1687 * test_io.c (test_close): IO manager which is used for testing
1690 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1692 * inode.c (ext2fs_get_next_inode): Separate out the function of
1693 setting up for a new block group to get_next_blockgroup().
1694 Separate out the function of reading in blocks of the
1695 inode table to get_next_blocks().
1697 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1699 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1700 blocks to the badblock list in sorted order. This allows
1701 badblocks_list_test to be coded using a binary search for
1704 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1706 * Release of E2fsprogs version 1.06
1708 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1710 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1711 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1714 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1715 set, then only write out the master superblock.
1717 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1719 * block.c (ext2fs_block_iterate): Fixed bug which caused
1720 block_iterate to fail to handle HURD created filesystems;
1721 it tested the inode translator field before the inode was
1724 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1726 * initialize.c (ext2fs_initialize): Make sure the description for
1727 the inode bitmap is set correctly.
1729 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
1731 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1733 * Release of E2fsprogs version 1.05
1735 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1737 * initialize.c: Override the kernel's idea of default
1738 checkinterval from 0 (never) to 180 days.
1740 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1742 * namei.c (ext2fs_namei_follow): New function which follows
1743 symbolic link (if any) at the target.
1745 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1747 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
1748 for shortcut function fs->read_inode() and fs->write_inode().
1749 Added inode_cache to reduce CPU time spent in doing
1752 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
1755 * namei.c (ext2fs_follow_link): New function.
1756 (ext2fs_namei): Extended to have support for chasing
1757 symbolic links. ext2fs_namei() still returns an inode
1758 which is a symbolic link. Symbolic links are only chased
1759 while resolving the containing directory. To chase
1760 symbolic links of the final result, use
1761 ext2fs_follow_link().
1763 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1765 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1767 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1768 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

1772 * initialize.c (ext2fs_initialize): On systems where the byte
1773 order is not i386 compatible, set the swap_byte flag.
1775 * inode.c (inocpy_with_swap): Check to see if inode contains a
1776 fast symlink before swapping the inode block fields. This
1777 required adding a new argument to inocpy_with_swap to
1778 determine whether the mode field is in host order or not.
1780 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1782 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1783 the sparc, if EXT2_STD_BITOPS set, use the standard
1784 i386-compatible bitmask operations, instead on the
1785 non-standard native bitmask operators.
1787 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1789 * block.c (ext2fs_block_iterate): Cause block iterator to return
1790 the HURD translator block (along with everything else).
1791 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1792 iterator, then don't return any meta data blocks
1793 (including the HURD translator).
1795 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1797 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1799 * uuid.c: New file, containing UUID utility functions.
1801 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1803 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1805 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1807 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1809 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1811 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1812 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1813 that's a basic value that must be correct for the rest of
1814 the library to work.
1816 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1819 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1821 * Release of E2fsprogs version 1.04

1827 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
1829 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
1830 Change the m68k bit numbering for bitmasks to match with
1831 the bit numbering used by all other ext2 implementations.
1833 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1835 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
1836 ext2fs_open_inode_scan): Support dynamically-sized inodes.
1838 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>

1849 the passed in size is *really* too small.
1851 * alloc.c (ext2fs_new_inode):
1852 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
1855 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
1857 * getsize.c (ext2fs_get_device_size): Open the device read-only
1858 when trying to determine its size.
1860 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1862 * Release of E2fsprogs version 1.02
1864 Sat Dec 9 09:57:50 1995 <tytso@rsts-11.mit.edu>

1867 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1868 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1869 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1870 to avoid conflicts with with kernel include files. Also
1871 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1874 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1876 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1878 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1879 s_def_resuid and s_def_resgid for backwards compatibility.
1881 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
1883 * bitops.h: Added #ifdef's for Sparc.
1885 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
1887 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
1890 * closefs.c: #include <string.h> to pick up memset() declaration
1892 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1894 * Makefile.in: Added support for BSD shared libraries.
1896 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1899 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1901 * unix_io.c (unix_open): Add a double check; if the passed in name
1902 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1904 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1906 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
1908 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
1911 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
1913 * getsize.c (ext2fs_get_device_size): Add support for reading the
1914 partition size from a BSD disk label.
1916 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1918 * getsize.c (ext2fs_get_device_size): New function that determins
1919 the size of a device. Used by mke2fs and e2fsck.
1921 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1923 * Makefile.in (install): Install static libraries in $(ulibdir)
1924 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
1926 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
1928 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1929 Move these functions to freefs.c.
1931 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1932 descriptors shadow memory to keep purify quiet. (This
1933 also has the nice benefit that the unused portion of the
1934 shadow descriptors are zeroed out.)
1936 * dirblock.c (ext2fs_write_dir_block): We need to use
1937 dirent->rec_len *before* it's byteswapped to find the
1938 location of the next directory structure!
1940 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1941 cause ext2fs_new_inode to loop infinitely if we're trying
1942 to allocate an inode in group #0 and there are no free
1943 inodes at all in the system.
1945 * closefs.c: #include <errno.h> if it exists.
1947 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1949 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1955 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1956 installation directories correctly.
1958 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1960 * namei.c (process_dir_block):
1961 * mkdir.c (ext2fs_mkdir):
1962 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1963 to read/write the directory block.
1965 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1966 file containing functions for reading and writing
1967 directory blocks (byte swapping if necesssary)
1969 * block.c (block_iterate_ind, block_iterate_dind,
1970 block_iterate_tind): Byte swap the block addresses if
1971 EXT2_SWAP_BYTES is set (and swap them back before writing
1974 * inode.c (inocpy_with_swap): New function.
1975 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1976 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1978 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1979 the superblock and group descriptors before writing it out.
1981 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1982 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1983 and group descriptors.
1985 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1986 to desp ext2 filesystem structures.
1988 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1989 supplied by Pete A. Zaitcev so that the C language
1990 versions of these functions are more portable. They will
1991 now work on both little and big endian systems, and the
1992 assumption that 32-bit integers are used is gone.
1994 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1995 doing byte swapping.
1997 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1998 byte swapping should take place.
2000 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

2007 Added new error codes.
2009 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
2011 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
2012 if the magic number is correct, it will be allocated.
2014 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
2016 * block.c (block_iterate_ind, block_iterate_dind,
2017 block_iterate_tind): Don't recompute block_nr each loop;
2018 just increment it! Factor check of BLOCK_FLAG_APPEND out
2019 of the loop. Factor mask of BLOCK_CHANGED into changed
2020 variable out of the loop. (block_iterate_ind, in
2021 particular, gets called a lot, so every little
2022 optimization helps.)
2024 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
2026 * block.c (block_iterate_ind, block_iterate_dind,
2027 block_iterate_tind): Precompute limit of loop to speed up
2028 block_iterate_ind and company.
2030 * bitops.h (ext2fs_fast_mark_block_bitmap,
2031 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
2032 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
2033 ext2fs_fast_test_inode_bitmap): Add fast version of these
2034 functions, which don't do range checking.
2036 * bitops.h (ext2fs_get_block_bitmap_start,
2037 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2038 ext2fs_get_inode_bitmap_end): Add new accessor functions
2039 which return the start and end points of the bitmaps.
2041 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2043 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2044 instead of llseek. The errno if the offset is too large
2045 and lseek is not supported should be EINVAL, not -EINVAL.
2047 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2049 * Makefile.in: Added support for ELF shared libraries.
2050 Fixed typos in the compilation rules.
2051 (distclean): Added Makefile.
2053 * llseek.c (llseek): New function, if llseek() does not exist in the
2055 (ext2_llseek): Changed to call llseek().
2057 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2059 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.

2063 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2065 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2066 the S_*, which are normally defined in <sys/stat.h>. This
2067 allows us to compile e2fsprogs on a non-Linux system,
2068 which may have a different value for S_IFDIR.
2070 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2072 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2073 this is a user-mode application!
2075 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2077 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2078 __linux__ so that non-linux systems won't see it.
2080 * alloc.c: Include <errno.h> if possible.
2081 * badblocks.c: Ditto.
2082 * bb_inode.c: Ditto.
2085 * expanddir.c: Ditto.
2086 * get_pathname.c: Ditto.
2087 * initialize.c: Ditto.
2094 * rw_bitmaps.c: Ditto.
2097 * Makefile.in: Rewritten to conform to GNU coding standards and
2098 support separate compilation directories.

2102 * initialize.c (ext2fs_initialize): Don't allow more than one
2103 bitmaps's worth of inodes in a group.
2105 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2107 * llseek.c (ext2_llseek): Added error checking to the llseek()
2108 compat code to protect against overflow. This only
2109 applies to 1.0 and early 1.1 kernels, which don't support
2110 the llseek() system call.
2112 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2114 * unix_io.c (unix_open): Initialize the read_error and write_error
2115 io_channel pointers to be null.
2117 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2118 found, clear it but don't try to update the filesystem
2119 accounting information, since that's hopeless anyway.
2121 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2122 bloblock_iterate_tind): Check to see if the indirect blocks are
2123 valid before trying to read them.
2125 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
2126 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2128 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2129 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2130 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2131 illegal block or inode number is passed in, return instead
2132 of trying to test, set, or clear the bit.
2134 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2136 * Makefile: Added a dummy install target in case shared libraries
2139 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2141 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
2142 the real last block of the bitmap should be calculated.
2144 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)

2147 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
2148 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
2149 ext2fs_free_block_bitmap): Add magic number checking for
2150 the inode and block bitmaps.
2152 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2153 magic number for a block bitmap instead of an inode bitmap.

2156 magic number checking for the inode_scan structure.
2158 * badblocks.c (badblocks_list_free, badblocks_list_add,
2159 badblocks_list_test, badblocks_list_iterate_begin,
2160 badblocks_list_iterate, badblocks_list_iterate_end): Add
2161 magic number checking for the badblocks_list and
2162 badblocks_iterate structures.
2164 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
2165 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,

2167 both for io_channel structure and unix_private_data
2170 * openfs.c (ext2fs_open): Add check for io_manager structure's
2173 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2174 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2175 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2176 * read_bb.c (ext2fs_read_bb_inode):
2177 * read_bb_file.c (ext2fs_read_bb_FILE):

2202 structure magic numbers.
2204 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2205 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2206 someone uses the -b option to specify the use of the backup
2207 superblock --- this usually means that the main superblock is
2211 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2212 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2213 revision level to the superblock.
2215 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2222 * initialize.c: Completely revamped the inode and block bitmap
2223 structures, so that they can be better chance of being extensible
2224 in a shared library. They are now their own type, instead of
2225 being a char *. Also, the function signatures of
2226 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2227 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2228 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2229 changed to eliminate the ext2_filsys argument, since it is no
2232 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2234 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2235 system call if available.
2237 * llseek.c: new file. This is the stub calling the llseek system
2238 call which allows supports for 2GB+ file systems.
2240 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2241 the creator operating system.
2243 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2245 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2246 the group descriptor statistics in addition to everything else.
2247 This relieves mke2fs of the responsibility of doing it.
2249 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2250 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2251 not the generic C function equivalents should be included or not.
2253 * openfs.c (ext2fs_open): If a superblock is specified, then use
2254 the backup group descriptors that go along with this superblock,
2255 instead of using the primary group descriptors. This allows
2256 e2fsck to recover filesystems where the primary group descriptors
