1 2001-07-29 Theodore Tso <tytso@valinux.com>
3 * finddev.c (scan_dir): Fix memory leak; we weren't calling
4 closedir() when exiting the function in all cases.
6 2001-07-27 Theodore Tso <tytso@valinux.com>
8 * mkjournal.c (ext2fs_create_journal_superblock): Set the first
9 block usable in the journal for external journals to be 2
10 or 3, depending on the blocksize, so that the existing
11 kernel code does the right thing.
13 * getsize.c (ext2fs_get_device_size): Add support for the
14 BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches
15 from Ben LaHaise, but it's likely this interface won't
18 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
19 when writing the journal superblock, too. (Oops! Needed
20 to make 1k filesystems with external journal to work.)
22 2001-07-26 Theodore Tso <tytso@valinux.com>
24 * mkjournal.c (ext2fs_add_journal_device): Use the correct block
25 to find the journal superblock if the blocksize is 1024.
27 2001-07-21 Theodore Tso <tytso@valinux.com>
29 * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code
31 2001-07-20 Theodore Tso <tytso@valinux.com>
33 * ext_attr.c (ext2fs_write_ext_attr): When writing the extended
34 attribute block, set the filesystem changed bit.
36 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
37 Comment out these functions since we're not using them.
39 2001-07-10 Theodore Tso <tytso@valinux.com>
41 * closefs.c (write_primary_superblock): After writing changes to
42 the primary superblock, update the original superblock
43 copy so we don't have to re-write those changes in the
45 (ext2fs_flush): Clear the superblock dirty flag after
46 we've flushed out changes to disk.
48 2001-07-07 Theodore Tso <tytso@valinux.com>
50 * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx
51 to avoid register conflicts when compiling in PIC mode.
53 2001-07-04 Theodore Tso <tytso@valinux.com>
55 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
56 Add new functions (C and in i386 assembler) which quickly
57 find bits set in a bitmask.
59 2001-06-23 Theodore Tso <tytso@valinux.com>
61 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
62 ext2_ext_attr.h and ext_attr.c for extended attributes
65 * Release of E2fsprogs 1.22
67 2001-06-22 Theodore Tso <tytso@valinux.com>
69 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
70 descriptor so that adding a journal to a mounted
71 filesystem doesn't die. (Fixes a bug accidentally
72 introduced in e2fsprogs 1.21.)
74 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
75 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
76 fchflags without defining UF_NODUMP. (Addresses Debian
79 * flushb.c: Use platform independent method of defining the
80 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
81 since on newer glibc's BLKFLSBUF is defined there.
83 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
84 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
85 to support byte swapping even if we don't support the
86 conversion functions. (Fixes Debian bug #101686).
88 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
89 since the byte-swapping code all assumes the
90 ext2_dir_entry structure. (It's a question of whether or
91 not name_len should be byte-swapped or not, and whether
92 it's a 16 bit or 8 bit field.)
94 2001-06-15 Theodore Tso <tytso@valinux.com>
96 * Release of E2fsprogs 1.21
98 2001-06-15 Theodore Tso <tytso@valinux.com>
100 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
101 file which is generated and is therefore found in the
102 build directory, not source directory.
104 * ismounted.c (check_mntent_file): Use a test file in / to check
105 to see if the root filesystem is mounted read-only. This
106 protects against the case where /etc might not be on /, as
107 well as the case where /etc/mtab doesn't exist. (Both are
108 should-never happen scenarios, but you never know...)
110 2001-06-14 Theodore Tso <tytso@valinux.com>
112 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
113 Remove unneeded #pragma argsused, since the arguments are
116 2001-06-13 Theodore Tso <tytso@valinux.com>
118 * ext2_types.h.in: If linux/types.h has been defined, then don't
119 try to redefine the typedefs.
121 * Makefile.in (HFILES): Add ext2_types.h to the list of files
122 which should be installed.
124 * ismounted.c (check_mntent_file): Work around GNU hurd brain
125 damage. Addresses Debian bug #100304.
127 * Makefile.in: Limit some .o files from being included into the
128 library if --disable-debugfs, --disable-swapfs,
129 --disable-imager, or --disable-resizer are used.
131 2001-06-12 Theodore Tso <tytso@valinux.com>
133 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
134 function, and use the ext2fs_badblocks_* functions
137 2001-06-11 Theodore Tso <tytso@valinux.com>
139 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
140 ext2fs_mark_generic_bitmap and
141 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
142 functions. (This saves space and doesn't significantly
143 change the speed of e2fsck on a P-III.)
145 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
146 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
147 include the byte-swapping logic if ENABLE_SWAPFS is turned
148 on or if we're on a big-endian machine.
150 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
151 set EXT2_FLAG_SWAP_BYTES, instead of using
154 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
155 autoconf to determine whether or not return
156 EXT2_FLAG_SWAP_BYTES.
158 2001-06-10 Theodore Tso <tytso@valinux.com>
160 * Makefile.in: Remove the dependence on the libe2p library.
162 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
163 with direct usage of the ioctl/fchflags so that we don't
164 have to depend on the libe2p library.
166 2001-06-08 Theodore Tso <tytso@valinux.com>
168 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
169 when trying to find a 32-bit wide type.
171 * icount.c (insert_icount_el): Fix the code used to estimate the
172 size of the new icount array to be more intelligent, to
173 avoid reallocating the array too many times. Thanks to
174 Enrique Perez-Terron for pointing this out.
176 2001-06-02 Theodore Tso <tytso@valinux.com>
178 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
179 for a symlink to determine whether it is a fast symlink.
181 2001-06-01 Theodore Tso <tytso@valinux.com>
183 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
184 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
186 2001-05-25 Theodore Tso <tytso@valinux.com>
188 * Release of E2fsprogs 1.20
190 2001-05-25 Theodore Tso <tytso@valinux.com>
192 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
193 some to clean up Andreas's patches. Use strncpy instead
194 of strcpy to save the root's mountpoint. Clean up #ifdef
195 structure. Remove uneeded variable in testing/debug driver.
197 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
199 * ismounted.c: Add check for root device which doesn't depend on
200 /etc/fstab or /proc/mounts to be correct. Don't call
201 endmntent() before we are done with mnt struct.
203 2001-05-23 Theodore Tso <tytso@valinux.com>
205 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
208 2001-05-21 Theodore Tso <tytso@valinux.com>
210 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
211 make room for pre-existing usage of
212 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
213 the same codepoint as EXT2_BTREE_FL.
215 2001-05-20 Theodore Tso <tytso@valinux.com>
217 * ext2fs.h: #include <> instead of "" for ext2fs and et header
218 files, since they will be installed in /usr/include
220 2001-05-14 Theodore Tso <tytso@valinux.com>
222 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
223 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
224 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
225 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,

232 tst_badblocks.c, tst_byteswap.c, tst_getsize.c,
233 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
234 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
235 Adjust all files in this directroy to include this file.
237 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
240 2001-05-05 Theodore Tso <tytso@valinux.com>
242 * fileio.c (ext2fs_file_read): Factored out common code and
243 cleaned up function. Fixed a bug where if there was an
244 error reading from the disk, the number of bytes read
245 wasn't reliably set. (Fixes Debian bug #79163)
246 (ext2fs_file_write): Factored out common code and made
247 function more efficient; if writing a full block, don't
248 bother to do a read-modify-write cycle.
250 2001-05-04 Theodore Tso <tytso@valinux.com>
252 * dirblock.c (ext2fs_read_dir_block): Check for an directory
253 record length which isn't a multiple four, and treat that
254 as an invalid. Scan the directory and return an error
255 (EXT2_ET_DIR_CORRUPTED) if the directory records are
257 (ext2fs_write_dir_block): If while byte-swapping the
258 directory block, if there's an error, abort and return
259 EXT2_ET_DIR_CORRUPTED.
261 2001-05-02 Theodore Tso <tytso@valinux.com>
263 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
264 image_header field in the ext2_filsys structure
266 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
267 * inode.c (ext2fs_read_inode):
268 * rw_bitmaps.c (read_bitmaps):
269 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
271 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
272 sure the full bitmap is saved.
274 2001-05-01 Theodore Tso <tytso@valinux.com>
276 * e2image.h (struct ext2_image_hdr): Add space for the device name
279 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
280 make sure the rec_len is a multiple of 4, to prevent
281 bus-errors on architectures which care about mis-aligned
284 2001-04-25 Theodore Tso <tytso@valinux.com>
286 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
287 query the device sizes using the BLKGETSIZE ioctl.
289 2001-04-16 Theodore Tso <tytso@valinux.com>
291 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
292 before checking /etc/mtab. The EXT2_MF_READONLY flag is
293 now set from the /etc/mtab options field for all
294 filesystems, not just the root filesystem. Add debugging
295 code to make it easier to test ext2fs_check_if_mounted().
297 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
298 check; return an error if there's an attempt to create a
299 journal less than 1024 filesystem blocks.
301 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
302 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
304 2001-02-20 Theodore Tso <tytso@valinux.com>
306 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
309 * tst_byteswap.c: New function to test the byteswap functions.
310 Add to regression test suite.
312 2001-02-08 Theodore Tso <tytso@valinux.com>
314 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
316 2001-02-07 Theodore Tso <tytso@valinux.com>
318 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
319 of s_first for external devices to always be 1, since
320 jsb->s_first is always relative to the start of the
321 journal superblock. Use htonl(1) when setting s_nr_users.
323 2001-01-17 Theodore Ts'o <tytso@valinux.com>
325 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
326 device number of the filesystem (instead of the journal)
327 was being dropped into s_journal_dev.
329 2001-01-15 Theodore Ts'o <tytso@valinux.com>
331 * initialize.c (ext2fs_initialize): Add support for initializing
332 the ext2 superblock for external journal devices. This
333 basically means we don't bother to allocate any block
336 * openfs.c (ext2fs_open): Only open external journal devices if
337 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
338 ext2fs_open. When opening such devices, don't try to read
339 the block group descriptors, since they're not there.
341 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
343 * mkjournal.c: Export a new function,
344 ext2fs_create_journal_superblock(), which allocates and
345 returns a buffer containing a journal superblock. This is
346 needed by mke2fs to create an external journal. Rewrote
347 ext2fs_add_journal_device() so that it no longer creates
348 the external journal, but rather adds a filesystem to an
349 existing external journal. It handles all of the UUID
352 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
353 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
354 Changed function prototype for ext2fs_add_journal_device().
356 2001-01-14 Theodore Ts'o <tytso@valinux.com>
358 * closefs.c (ext2fs_flush): Don't write out anything beyond the
359 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
362 2001-01-12 Theodore Ts'o <tytso@valinux.com>
364 * imager.c: Fix gcc -Wall complaints and a series of bugs where
365 retval wasn't set correctly. (Thanks to Andreas Dilger
366 for pointing this out.)
368 2001-01-11 <tytso@snap.thunk.org>
370 * flushb.c (ext2fs_sync_device): New function which centralizes
371 all of the places which might try to use the BLKFLSBUF
372 or FDFLUSH ioctls (and usually failing to define them
373 since the system header files don't usually do this for
374 us, and we're trying to avoid usage of kernel include
377 2001-01-10 <tytso@snap.thunk.org>
379 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
380 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
381 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
382 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
383 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
384 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
385 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
386 ext2_ino_t, to protect applications that attempt to
387 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
388 changes ino_t(!?). So we use ext2_ino_t to avoid an
389 unexpected ABI change.
391 2001-01-05 <tytso@snap.thunk.org>
393 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
394 we may overrun allocated memory in case of a corrupted
395 filesystem (or an e2fsck test case :-) when byte-swapping
398 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
400 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
401 complaints including a missing return 0 at the end of
402 ext2fs_add_journal_device.
404 2001-01-03 <tytso@snap.thunk.org>
406 * Makefile.in: Link in libe2p when creating libext2fs as a shared
407 library, since mkjournal.c now references fsetflags().
409 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
410 Dilger's changes (with fixups) to allow on-line creation
413 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
414 EXT2_FLAG_SUPER_ONLY, which the close routines to only
415 update the superblock, and not the group descriptors.
417 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
419 * ismounted.c: add ext2fs_check_mount_point() function, which will
420 optionally return the mount point of a device if mounted
422 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
424 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
425 ext2fs_add_journal_inode()
427 2001-01-01 <tytso@snap.thunk.org>
429 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
430 source (but not binary) compatibility of some users of the
431 ext2 library. They should just simply do a global search
432 and replace of struct ext2fs_sb with struct
433 ext2_super_block, and use their own private copy of
434 ext2_fs.h if they aren't already.
436 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
437 Replace use of ext2fs_sb with ext2_super_block.
439 2000-12-31 <tytso@snap.thunk.org>
441 * ext2fs.h: Cleaned up header file by removing definitions of
442 feature flags that might not have been defined in older
443 ext2 header files. Now that we're using our own
444 include/linux/ext2fs.h header file, this can never happen.
446 * jfs_dat.h: Removed old header file which is no longer needed.
448 2000-12-13 Theodore Ts'o <tytso@valinux.com>
450 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
451 by Andreas Dilger to update the filesystem revision to
454 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
457 2000-12-09 <tytso@snap.thunk.org>
459 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
460 ext2fs_add_journal_device): Add a new argument to the APIs
461 of these function, which is a flags word. This is used to
462 allow the creation of a V1 superblock for those folks who
463 are using ext3 0.3b in production. Note, the user-land
464 interface for getting at this flag won't be documented, as
465 the V1 superblock is deprecated.
467 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
468 which creates a V2 superblock instead of a V1 superblock.
470 2000-11-21 <tytso@snap.thunk.org>
472 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
473 out by Andreas Dilger.
475 2000-11-05 <tytso@snap.thunk.org>
477 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
478 ext2_fs.h, Makefile.in: New file that has routines that
479 save ext2fs metadata to a file.
481 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
483 * e2image.h: New file which defines the file format for the ext2
484 image file. (Saved copy of ext2 metadata to a file as a
485 saving throw against worst-case damage.)
487 2000-11-01 <tytso@snap.thunk.org>
489 * inode.c (ext2fs_flush_icache): Add new function
490 ext2fs_flush_icache() which flushes the internal inode
491 cache. Applications which modify the inode table blocks
492 directly must call this function.
494 2000-10-26 <tytso@snap.thunk.org>
496 * mkjournal.c: Add #include of netinet/in.h, since Solaris
497 requires it for ntohl().
499 * ext2_io.h (io_channel_write_byte): Add new interface to allow
500 callers to write specific byte ranges. This is an
501 optional interface, which not all IO channels may
504 * unix_io.c (unix_write_byte):
505 * test_io.c (test_write_byte): Add implementation of the
508 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
509 function which writes the primary superblock. If the IO
510 channel supports writing raw bytes directly, only fields
511 which were modified are written to the disk. This makes
512 it safe(r) to use utilities like tune2fs on a mounted
515 * freefs.c (ext2fs_free): Free the original superblock if it is
518 * openfs.c (ext2fs_open): Store a copy of the original superblock
521 * ext2fs.h: Add a field to store the original superblock in the
522 ext2 context structure.
524 2000-10-24 <tytso@snap.thunk.org>
526 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
527 don't need to use llseek).
529 2000-10-24 <tytso@valinux.com>

547 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
548 provides the function ext2fs_find_block_device(). This
549 function returns the pathname to a block device, given its
552 2000-07-13 <tytso@valinux.com>
554 * Release of E2fsprogs 1.19

589 2000-06-10 Theodore Ts'o <tytso@valinux.com>
591 * getsize.c (main): Add debugging code under #ifdef DEBUG
593 2000-05-27 Theodore Ts'o <tytso@valinux.com>
595 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode

599 2000-05-25 <tytso@snap.thunk.org>
601 * getsize.c (ext2fs_get_device_size): Use open64() instead of
602 open() if it exists. Under linux, manually define the
603 ioctl for BLKGETSIZE if it isn't already defined and it's
606 * unix_io.c (unix_open): Use open64() instead of open() if it
609 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
610 available (and prototypes are defined) use it in
611 preference to llseek.
613 * Makefile: Add hack dependency rule so that parallel makes work
616 2000-05-18 Theodore Ts'o <tytso@valinux.com>

626 how to define __s64 and __u64. Turn off "compression is
627 experimental" warning if the cpp macro
628 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
630 2000-02-11 <tytso@snap.thunk.org>
632 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
633 Conditionally include Compression as a supported type if
634 ENABLE_COMPRESSION (via --enable-compression) is turned on.

643 Change to return the previous state of the bit that is
644 being marked or unmarked. For speed optimization.
646 2000-02-02 Theodore Ts'o <tytso@valinux.com>
648 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
650 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
651 needed any more; we know it will always be i_generation.
652 Add support for swapping the high bits of the uid and gid.
654 1999-11-19 <tytso@valinux.com>
656 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link

667 1999-11-08 <tytso@valinux.com>
669 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
670 since ext2fs_badblocks_list_free was moved to freefs.c.
672 * tst_badblocks.c: Use the newer badblocks API names. Add
673 duplicate blocks to the test inputs to test dealing with
674 adding blocks which are already in the badblocks list.
676 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
677 of the list, use a shortcut O(1) operations instead of an
678 O(n) operation. (Idea suggested by David Beattie.)
680 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
681 of badblocks_list_free(), to save a procedure call.
683 1999-10-26 <tytso@valinux.com>
685 * Release of E2fsprogs 1.17
687 1999-10-26 <tytso@valinux.com>
689 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't

692 1999-10-25 <tytso@valinux.com>
694 * nt_io.c (_OpenNtName): Open the device using
695 FILE_SYNCHRONOUS_IO_NONALERT instead of
696 FILE_SYNCHRONOUS_IO_ALERT
697 (nt_open): At the end of the device open routine, unlock
698 the drive but do not dismount it.
700 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
703 1999-10-22 <tytso@valinux.com>
705 * Release of E2fsprogs 1.16
707 1999-10-22 <tytso@valinux.com>
709 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
711 * link.c (ext2fs_link): This call now uses the low three bits of
712 the flags parameter to pass the directory filetype
713 information; it will set the directory entry FILETYPE
714 information if the filesystem supports it.
716 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
717 option is set, then create the '.' and '..' entries with
718 the filetype set to EXT2_FT_DIR.
720 1999-09-24 <tytso@valinux.com>
722 * nt_io.c: New file which supports I/O under Windows NT.
724 1999-09-07 <tytso@valinux.com>
726 * ext2fs.h: Add new fields for journalling and define new
727 feature bits used by newer filesystems: IMAGIC_INODES,
728 HAS_JOURNAL, RECOVER.
730 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
731 we update the inode block count and size files so that the
732 block count field is updated correctly when we create an
735 1999-07-18 Theodore Ts'o <tytso@valinux.com>
737 * Release of E2fsprogs 1.15
739 1999-06-23 <tytso@valinux.com>
741 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
742 kernels that use i_generation instead of i_version. Patch
743 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
745 1999-06-21 <tytso@valinux.com>
747 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
748 directory entry before calling the callback function.
749 This should prevent some core dumps of insufficiently
750 paranoid callback functions.
752 1999-05-29 <tytso@rsts-11.mit.edu>
754 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
756 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
757 that we don't handle writing yet (we do). Fixed bug where
758 we weren't allocating a big enough buffer for ext2_bmap.
760 1999-05-03 <tytso@rsts-11.mit.edu>
762 * openfs.c (ext2fs_open): Check to make sure that the number of
763 blocks per group is not zero --- if so, it must be a bad
766 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
768 * Release of E2fsprogs 1.14
770 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
772 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
773 the inode number is zero; if it's zero, return
774 EXT2_ET_BAD_INODE_NUM.
776 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
778 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
779 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
782 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
784 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
785 non-Linux case to use EINVAL by default, unless it isn't
786 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
789 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
791 * Release of E2fsprogs 1.13
793 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
795 * Makefile.in: Updated dependencies.
797 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
799 * initialize.c (ext2fs_initialize): Make sure that we allocate
800 enough inodes so that we can make a valid filesystem.
802 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
804 * rw_bitmaps.c: Fixed signed/unsigned warnings.
806 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
807 function declaration.
809 * dblist.c (make_dblist): Add safety check in case the dblist
810 pointer passed in is null (in which case, assign it to
811 fs->dblist). Fixed some signed/unsigned warnings.
813 * bmap.c: Make addr_per_block be of type blk_t to avoid
814 signed/unsigned warnings.
816 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
817 function declaration.
819 * get_pathname.c (get_pathname_proc): Use return value from

824 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
825 from the function declaration.
827 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
828 return the error directly instead of jumping to the
829 cleanup routine, since we don't need to do any cleanup.
831 * alloc_table.c (ext2fs_allocate_group_table): Make this
832 function take a dgrp_t for its group argument.
834 * ext2fs.h: Make dgrp_t an __u32 type, and make
835 fs->desc_group_count be of type dgrp_t.
837 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
839 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
840 than 10 blocks when we need to expand the size of the
843 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
845 * Release of E2fsprogs 1.12
847 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
849 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
850 appropriate for all of the block group copies, so that
851 it's clear where the beginning of the filesystem is on the
852 disk. (For when the partition table gets scrod.)
854 * ext2fs.h: Change the name of the feature from
855 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
856 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
858 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
860 * inode.c (get_next_blockgroup): Fix bug where if
861 get_next_blockgroup() is called early because of a missing
862 inode table in a block group, the current_inode counter
863 wasn't incremented correctly.
865 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
867 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
868 against a completely trashed bad block inode.
870 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
872 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
873 the stride length hits a bad value, we retry the block
874 allocation starting at the beginning of the block group.
876 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
877 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
878 e2_blkcnt_t to avoid collision with LFS API.
880 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
882 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
883 way that avoids overflows on disk sizes greater than 4GB.
885 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
887 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
888 return type for comparison functions for qsort.
890 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
893 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
895 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
898 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
899 evade a potential problem with glibc's header files trying
900 to spike out linux/types.h.
902 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
903 include the old size of the memory, which is needed for
904 some braindamaged memory allocation systems that don't
907 * badblocks.c (ext2fs_badblocks_list_add):
908 bb_inode.c (clear_bad_block_proc):
909 dblist.c (ext2fs_add_dir_block):

919 convention. Fix uninstall rules to take $(DESTDIR) into
922 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
924 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
925 with 32 bit longs, then we need to manually define __s64
926 and __u64, since the current kernel header files don't
927 define these if __STRICT_ANSI__ is defined. This is a
928 problem if we are compiling with full GCC warnings, since
929 we do need 64 bit support.
931 * Makefile.in (OBJS): Remove bmove.o from files to be built,
932 since we're not using ext2fs_move_blocks() and there
933 is some question as to its usefulness in its current
936 * bmap.c (block_bmap): Remove unused function.
938 * bmove.c (process_block): Fix -Wall warning.
940 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
942 * block.c (ext2fs_block_iterate3): Make the ref_offset field
943 contain the offset into the inode.i_blocks array when
944 ref_block is zero. Since we haven't done a formal
945 release of e2fsprogs since block_iterate2 was first
946 introduced, I removed block_iterate2, and renamed
947 block_iterate3 to be block_iterate2.
949 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
950 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
951 use of block_iterate and block_iterate2 to
952 block_iterate2 with the new prototype for the
953 interator function. (using blkcnt_t forr blockcount)
955 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
957 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
958 s_prealloc_blocks, s_prealloc_dir_blocks). Added
959 conditional defines of new features COMPAT_DIR_PREALLOC,
960 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
961 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
962 the library to declare that we support COMPAT_DIR_PREALLOC,
963 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
965 * fileio.c: Rename function ext2fs_file_llseek to be
966 ext2fs_file_lseek, which is more accurate.
968 * block.c: Add new function ext2fs_block_iterate3 which calls
969 the iterator function with the blockcount argument of
970 type blkcnt_t. This version of the function is
971 allowed to handle large files; the other fucntions are
974 * ext2fs.h: Add new type blkcnt_t
976 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
978 * block.c (ext2fs_block_iterate2): Fix bug where the block count
979 field wasn't getting correctly incremented for sparse
980 files when the indirect or doubly-indirect block
981 specified in the inode was zero.
983 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
985 * unlink.c (unlink_proc):
986 * lookup.c (lookup_proc):
987 * link.c (link_proc):
988 * get_pathname.c (get_pathname_proc):
989 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
990 from dirent->name_len, so it can be used for other
993 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
994 and indicate that we have support for this incompatible
997 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
999 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

1004 number of directories when the block group information is
1007 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
1009 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
1010 inode table is missing so that we catch the case where the
1011 first block group is missing.
1013 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
1016 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1018 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
1020 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
1022 * test_io.c (test_flush): Add a debugging printf when the flush
1025 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
1026 read in, return right away.
1028 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1030 * bitops.h: Don't try to do i386 inline asm functions if the
1033 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
1034 instead of linux/types.h, and e2_bitops.h instead of
1037 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
1040 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
1042 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
1043 so that we don't need to call get_next_blockgroup() the
1044 first time around. Saves a bit of time, and prevents us
1045 from needing to assign -1 to current_group (which is an
1048 * icount.c (insert_icount_el): Cast the estimated number of inodes
1049 from a float to an ino_t.
1051 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

1061 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
1062 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is

1080 avoid C++ namespace clash.
1082 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
1083 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
1084 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
1085 unlink.c: Change private to be priv_data (to avoid C++
1088 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1090 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1091 paranoid about validating the directory counts from the
1092 block group information.
1094 * all files: Don't include stdlib.h anymore; include it in
1095 ext2_fs.h, since that file requires stdlib.h
1097 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1099 * expanddir.c (ext2fs_expand_dir): Check to make sure the block

1131 * [all files, basically]: Added definition of ext2fs_get_mem,
1132 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1133 changed all library routines to use these wrapper functions.

1136 instead of the system error messages.
1138 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
1141 * ext2fs.h: Added function declarations and constants for bmap.c

1151 physical block number.
1153 * fileio.c: New file which implements simple file reading and
1156 * alloc.c (ext2fs_alloc_block): New function which allocates a
1157 block, zeros it, and updates the filesystem accounting
1158 records appropriately.

1162 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
1163 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
1164 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
1166 * Change various library files to use these functions instead of
1167 EINVAL, ENOENT, etc.
1169 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1171 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we

1176 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1178 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H

1216 * io.h: Change the prototype of ext2fs_llseek() to use int's
1217 instead of unsigned int's.
1219 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1220 to make life easer for GNU Libc 2.
1222 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1223 filesystem has its bitmaps stored as 32-bit words with bit
1224 0 as the LSB of each word. Thus a bitmap with only bit 0
1225 set would be, as a string of bytes, 00 00 00 01 00 ... To
1226 cope with this, we byte-reverse each word of a bitmap if
1227 we have a big-endian filesystem, that is, if we are *not*
1228 byte-swapping other word-sized numbers.

1288 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
1289 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c

1294 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
1295 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
1297 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1299 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1300 is zero, then return EXT2_IO_LLSEEK_FAILED.
1302 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1304 * Release of E2fsprogs 1.11
1306 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1308 * dblist.c (ext2fs_dblist_count): Added new function which returns
1309 the number of directory blocks in dblist.
1311 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1313 * unix_io.c (unix_flush): Make the io_channel flush function do a
1314 fsync to flush the kernel buffers to disk.
1316 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1318 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1319 current inode number wasn't being set by the
1320 goto_blockgroup function.
1322 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1324 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1325 of blocks which need to be moved, and moves those blocks
1326 to another location in the filesystem.
1328 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1329 bitmap, make sure all of the new parts of the bitmap are
1332 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1334 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1335 wasn't being returned to the caller.
1337 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1338 ext2fs_allocate_group_table() which sets the group tables
1339 for a particular block group. The relevant code was
1340 factored out of ext2fs_allocate_tables().
1342 * dblist.c (make_dblist): Adjust the initial size of the directory
1343 block list to be a bit more realistic (ten plus twice the
1344 number of directories in the filesystem).
1346 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1348 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1349 ext2fs_badblocks_list_test would test the list (and exceed
1350 array boundaries) if there were no bad blocks on the bad
1351 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1353 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1355 * Release of E2fsprogs version 1.10
1357 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1359 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1360 inode and block bitmaps based on the RAID 0 stride
1361 parameter (which is passed by mke2fs).
1363 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1364 mke2fs to communicate the stride length to
1365 ext2fs_allocate_tables()
1367 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1369 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1370 systems. (We can't assume that the new filesystem types
1373 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1375 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1376 allocate the inode and block bitmaps inside block group at
1379 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1381 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1382 filesystem has no free blocks, ext2fs_new_block would loop
1385 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1387 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1388 free if refcount goes to zero.

1397 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1398 badblocks structure.
1400 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1402 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
1404 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1406 (unix_close, test_close): Decrement the refcount and only
1407 close the io_channel if the refcount goes to 0.
1409 * io.h: Add refcount to the io_channel structure. Add new macro
1410 interface io_channel_bumpcount() to bump the refcount.
1412 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1414 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1415 cache in the filesystem handle, instead of the inode cache
1416 in a static variable.
1418 * freefs.c: Added static function to free the inode cache (called by
1421 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1423 * ext2fs.h: Added pointer to the inode_cache structure.

1428 block count field automatically.
1430 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1432 * Release of E2fsprogs version 1.09
1434 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1436 * version.c (ext2fs_parse_version_string): Check the passed in
1437 version string (instead of the hard-coded one).
1439 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1440 greater filesystem size, clamp it to prevent allocating a
1441 block or inode bitmap beyond the filesystem.
1443 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1444 overhead calculation was accidentally removed.
1446 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1448 * Release of E2fsprogs version 1.08
1450 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1453 block of a dblist entry, given the directory inode and
1456 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1458 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1459 inode bitmaps at staggered locations across the block
1460 groups, to avoid concentrating the bitmaps on a small
1461 number of disks when using striped RAID arrays.
1463 * initialize.c (ext2fs_initialize): By default, choose the maximum
1464 possible number of blocks per group (based on the size of
1465 the bitmaps in the blocksize).
1467 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1469 * initialize.c (ext2fs_initialize): Add support for
1470 EXT2_COMPAT_SPARSE_SUPER feature.
1472 * closefs.c (ext2fs_bg_has_super): New function to determine
1473 whether or a particular block group should have a
1474 superblock and block group descriptor. Used for the
1475 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1476 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1477 or not the superblock should be written out for the block
1480 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1481 for sparse duplicate superblocks.
1483 * version.c (ext2fs_get_library_version): New function which
1484 returns the library version.
1486 * version.c (ext2fs_parse_version_string): New function which
1487 parses a version string and returns a version number,
1488 so application programs can compare version numbers as
1491 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1493 * icount.c (ext2fs_create_icount): Change function so that it also
1494 takes a new argument which contains a "hint" icount
1495 structure. This "hint" icount allows the create function
1496 to set up the sorted list in advance. This reduces
1497 significantly the amount of data moving needed to insert
1498 these inodes into the list later.
1500 * icount.c (ext2fs_icount_validate): New function which validates
1501 that the icount structure's rep invariant.
1503 * icount.c (get_icount_el): Completely revamped implementation
1504 to subsume put_icount_el(). Put_icount_el() used to
1505 use an O(N) implementation to insert in the middle
1506 of the icount list. It now uses a O(ln N) to search
1507 for where the icount should be inserted, and then uses
1508 a memcpy to move the list down (instead of a for loop).
1510 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1511 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1512 to see if the inode is within bounds; if it isn't, return
1515 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1516 when a bad inode number is passed to test_generic_bitmap
1517 to be EXT2FS_TEST_ERROR instead of the wrong
1518 EXT2FS_UNMARK_ERROR.
1520 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1522 * Release of E2fsprogs version 1.07
1524 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1526 * Makefile.in (ELF_VERSION): Change version to be 2.2
1528 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1530 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1531 ext2fs_fast_test_block_bitmap_range().
1533 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1534 ext2fs_test_block_bitmap_range: New inline functions which
1535 test to see whether a contiguous range of blocks is
1538 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1540 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1541 use ext2fs_badblocks_* instead of badblocks_*
1543 * bb_compat.c: New file which translates between old badblocks_*()
1544 names to ext2fs_badblocks_*()
1546 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1547 link.c (since e2fsck doesn't use ext2fs_unlink()).
1549 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1550 bitmap resizing routine moved from bitmaps.c, since e2fsck
1551 doesn't need to use this function.
1553 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1554 since e2fsck only needs ext2fs_lookup.
1556 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1558 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1559 already set; this is needed so that programs like dump
1560 which use the inode scan functions will deal with
1561 filesystems that have bad blocks in the inode table.
1563 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1565 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1566 Moved to ext2fsP.h, since it doesn't need to be part of
1567 the public interface.
1569 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1571 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1573 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1574 directory block list abstraction. (Code moved from
1577 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1578 to inode.c (since no one else should be peeking inside it!)
1580 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1582 * openfs.c (ext2fs_open): Check the feature set in the ext2
1583 superblock, and refuse to open filesystems if they contain
1584 incompatible features. (Can be overriden with the
1587 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1589 * block.c (ext2fs_block_iterate2): Added new function
1590 ext2fs_block_iterate2 which changes the function
1591 signature of the callback function to include the
1592 referencing block and offset.
1594 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1595 ext2fs_inode_scan_goto_blockgroup which allows an
1596 application to jump to a particular block group while
1597 doing an inode scan.
1599 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1601 * dirblock.c: Include string.h, since we use memcpy().
1603 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1605 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1606 a long not an int; this doesn't matter on i386 machines,
1607 but it does on Alpha's.
1609 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1611 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1612 table pointer is NULL, then return an error indicating
1613 that the inode table is missing.
1614 (get_next_blockgroup, get_next_blocks,
1615 ext2fs_get_next_inode): Don't treat a missing inode table
1616 as permanent error. Return MISSING_INODE_TABLE, but as an
1617 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1619 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1620 ext2fs_write_inode_bitmap): If the inode or block bitmap
1621 block is zero, then don't write out the inode or block
1622 bitmap. The idea here is to avoid stomping on the
1624 (read_bitmaps): If the inode or block bitmap block is
1625 zero, then fill in that portion of the inode or block
1626 bitmap with all zeros.
1628 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1629 blocks in inode table when the inode table size is
1630 non-standard (and can therefore span blocks).
1632 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1634 * alloc.c (ext2fs_new_block): Fix fencepost error in
1635 ext2fs_new_block; make sure we don't try to allocate the
1636 first block beyond the end of the filesystem.
1638 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1640 * inode.c (check_for_inode_bad_blocks): New function called by
1641 get_next_blocks() to avoid reading in bad blocks marked in
1642 fs->badblocks. Inodes located in bad blocks are returned
1643 by ext2fs_get_next_inode() returns the error code
1644 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1646 * alloc_tables.c (ext2fs_allocate_tables): New function which
1647 performs the part of mke2fs's job of allocating the
1650 * test_io.c (test_close): IO manager which is used for testing
1653 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1655 * inode.c (ext2fs_get_next_inode): Separate out the function of
1656 setting up for a new block group to get_next_blockgroup().
1657 Separate out the function of reading in blocks of the
1658 inode table to get_next_blocks().
1660 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1662 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1663 blocks to the badblock list in sorted order. This allows
1664 badblocks_list_test to be coded using a binary search for
1667 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1669 * Release of E2fsprogs version 1.06
1671 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1673 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1674 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1677 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1678 set, then only write out the master superblock.
1680 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1682 * block.c (ext2fs_block_iterate): Fixed bug which caused
1683 block_iterate to fail to handle HURD created filesystems;
1684 it tested the inode translator field before the inode was
1687 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1689 * initialize.c (ext2fs_initialize): Make sure the description for
1690 the inode bitmap is set correctly.
1692 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

1696 * Release of E2fsprogs version 1.05
1698 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1700 * initialize.c: Override the kernel's idea of default
1701 checkinterval from 0 (never) to 180 days.
1703 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1705 * namei.c (ext2fs_namei_follow): New function which follows
1706 symbolic link (if any) at the target.
1708 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1710 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
1711 for shortcut function fs->read_inode() and fs->write_inode().
1712 Added inode_cache to reduce CPU time spent in doing
1715 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
1718 * namei.c (ext2fs_follow_link): New function.
1719 (ext2fs_namei): Extended to have support for chasing
1720 symbolic links. ext2fs_namei() still returns an inode
1721 which is a symbolic link. Symbolic links are only chased
1722 while resolving the containing directory. To chase
1723 symbolic links of the final result, use
1724 ext2fs_follow_link().
1726 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1728 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1730 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1731 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

1735 * initialize.c (ext2fs_initialize): On systems where the byte
1736 order is not i386 compatible, set the swap_byte flag.
1738 * inode.c (inocpy_with_swap): Check to see if inode contains a
1739 fast symlink before swapping the inode block fields. This
1740 required adding a new argument to inocpy_with_swap to
1741 determine whether the mode field is in host order or not.
1743 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1745 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1746 the sparc, if EXT2_STD_BITOPS set, use the standard
1747 i386-compatible bitmask operations, instead on the
1748 non-standard native bitmask operators.
1750 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1752 * block.c (ext2fs_block_iterate): Cause block iterator to return
1753 the HURD translator block (along with everything else).
1754 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1755 iterator, then don't return any meta data blocks
1756 (including the HURD translator).
1758 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1760 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1762 * uuid.c: New file, containing UUID utility functions.
1764 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1766 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1768 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1770 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1772 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1774 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1775 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1776 that's a basic value that must be correct for the rest of
1777 the library to work.
1779 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1782 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1784 * Release of E2fsprogs version 1.04

1790 Tue Mar 26 12:06:32 1996 <tytso@rsts-11.mit.edu>
1792 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
1793 Change the m68k bit numbering for bitmasks to match with
1794 the bit numbering used by all other ext2 implementations.
1796 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1798 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
1799 ext2fs_open_inode_scan): Support dynamically-sized inodes.
1801 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>

1812 the passed in size is *really* too small.
1814 * alloc.c (ext2fs_new_inode):
1815 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
1818 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
1820 * getsize.c (ext2fs_get_device_size): Open the device read-only
1821 when trying to determine its size.
1823 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1825 * Release of E2fsprogs version 1.02
1827 Sat Dec 9 09:57:50 1995 <tytso@rsts-11.mit.edu>

1830 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1831 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1832 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1833 to avoid conflicts with with kernel include files. Also
1834 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1837 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1839 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1841 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1842 s_def_resuid and s_def_resgid for backwards compatibility.
1844 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
1846 * bitops.h: Added #ifdef's for Sparc.
1848 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
1850 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
1853 * closefs.c: #include <string.h> to pick up memset() declaration
1855 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1857 * Makefile.in: Added support for BSD shared libraries.
1859 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1862 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1864 * unix_io.c (unix_open): Add a double check; if the passed in name
1865 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1867 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1869 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
1871 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
1874 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
1876 * getsize.c (ext2fs_get_device_size): Add support for reading the
1877 partition size from a BSD disk label.
1879 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1881 * getsize.c (ext2fs_get_device_size): New function that determins
1882 the size of a device. Used by mke2fs and e2fsck.
1884 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1886 * Makefile.in (install): Install static libraries in $(ulibdir)
1887 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
1889 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
1891 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1892 Move these functions to freefs.c.
1894 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1895 descriptors shadow memory to keep purify quiet. (This
1896 also has the nice benefit that the unused portion of the
1897 shadow descriptors are zeroed out.)
1899 * dirblock.c (ext2fs_write_dir_block): We need to use
1900 dirent->rec_len *before* it's byteswapped to find the
1901 location of the next directory structure!
1903 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1904 cause ext2fs_new_inode to loop infinitely if we're trying
1905 to allocate an inode in group #0 and there are no free
1906 inodes at all in the system.
1908 * closefs.c: #include <errno.h> if it exists.
1910 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1912 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1918 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1919 installation directories correctly.
1921 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1923 * namei.c (process_dir_block):
1924 * mkdir.c (ext2fs_mkdir):
1925 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1926 to read/write the directory block.

1929 file containing functions for reading and writing
1930 directory blocks (byte swapping if necesssary)
1932 * block.c (block_iterate_ind, block_iterate_dind,
1933 block_iterate_tind): Byte swap the block addresses if
1934 EXT2_SWAP_BYTES is set (and swap them back before writing
1937 * inode.c (inocpy_with_swap): New function.
1938 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1939 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1941 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1942 the superblock and group descriptors before writing it out.
1944 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1945 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1946 and group descriptors.
1948 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1949 to desp ext2 filesystem structures.
1951 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1952 supplied by Pete A. Zaitcev so that the C language
1953 versions of these functions are more portable. They will
1954 now work on both little and big endian systems, and the
1955 assumption that 32-bit integers are used is gone.
1957 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1958 doing byte swapping.
1960 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1961 byte swapping should take place.
1963 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

1974 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1975 if the magic number is correct, it will be allocated.
1977 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1979 * block.c (block_iterate_ind, block_iterate_dind,
1980 block_iterate_tind): Don't recompute block_nr each loop;
1981 just increment it! Factor check of BLOCK_FLAG_APPEND out
1982 of the loop. Factor mask of BLOCK_CHANGED into changed
1983 variable out of the loop. (block_iterate_ind, in
1984 particular, gets called a lot, so every little
1985 optimization helps.)
1987 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1989 * block.c (block_iterate_ind, block_iterate_dind,
1990 block_iterate_tind): Precompute limit of loop to speed up
1991 block_iterate_ind and company.
1993 * bitops.h (ext2fs_fast_mark_block_bitmap,

1995 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1996 ext2fs_fast_test_inode_bitmap): Add fast version of these
1997 functions, which don't do range checking.
1999 * bitops.h (ext2fs_get_block_bitmap_start,
2000 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
2001 ext2fs_get_inode_bitmap_end): Add new accessor functions
2002 which return the start and end points of the bitmaps.
2004 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
2006 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
2007 instead of llseek. The errno if the offset is too large
2008 and lseek is not supported should be EINVAL, not -EINVAL.
2010 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
2012 * Makefile.in: Added support for ELF shared libraries.
2013 Fixed typos in the compilation rules.
2014 (distclean): Added Makefile.
2016 * llseek.c (llseek): New function, if llseek() does not exist in the
2018 (ext2_llseek): Changed to call llseek().
2020 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2022 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.

2026 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
2028 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
2029 the S_*, which are normally defined in <sys/stat.h>. This
2030 allows us to compile e2fsprogs on a non-Linux system,
2031 which may have a different value for S_IFDIR.
2033 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
2035 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
2036 this is a user-mode application!
2038 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
2040 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
2041 __linux__ so that non-linux systems won't see it.
2043 * alloc.c: Include <errno.h> if possible.
2044 * badblocks.c: Ditto.
2045 * bb_inode.c: Ditto.
2048 * expanddir.c: Ditto.
2049 * get_pathname.c: Ditto.
2050 * initialize.c: Ditto.
2057 * rw_bitmaps.c: Ditto.
2060 * Makefile.in: Rewritten to conform to GNU coding standards and
2061 support separate compilation directories.
2063 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
2065 * initialize.c (ext2fs_initialize): Don't allow more than one
2066 bitmaps's worth of inodes in a group.
2068 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
2070 * llseek.c (ext2_llseek): Added error checking to the llseek()
2071 compat code to protect against overflow. This only
2072 applies to 1.0 and early 1.1 kernels, which don't support
2073 the llseek() system call.
2075 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2077 * unix_io.c (unix_open): Initialize the read_error and write_error
2078 io_channel pointers to be null.
2080 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2081 found, clear it but don't try to update the filesystem
2082 accounting information, since that's hopeless anyway.
2084 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2085 bloblock_iterate_tind): Check to see if the indirect blocks are
2086 valid before trying to read them.
2088 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
2089 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
2091 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
2092 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2093 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2094 illegal block or inode number is passed in, return instead
2095 of trying to test, set, or clear the bit.
2097 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
2099 * Makefile: Added a dummy install target in case shared libraries
2102 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
2104 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

2111 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
2112 ext2fs_free_block_bitmap): Add magic number checking for
2113 the inode and block bitmaps.
2115 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
2116 magic number for a block bitmap instead of an inode bitmap.

2124 magic number checking for the badblocks_list and
2125 badblocks_iterate structures.
2127 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
2128 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
2129 unix_write_blk, unix_flush): Add magic number checking
2130 both for io_channel structure and unix_private_data
2133 * openfs.c (ext2fs_open): Add check for io_manager structure's
2136 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
2137 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
2138 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
2139 * read_bb.c (ext2fs_read_bb_inode):
2140 * read_bb_file.c (ext2fs_read_bb_FILE):
2141 * newdir.c (ext2fs_new_dir_block):
2142 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):

2144 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
2145 ext2fs_write_inode, ext2fs_get_blocks,
2146 ext2fs_check_directory):

2164 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2165 structure magic numbers.
2167 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2168 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2169 someone uses the -b option to specify the use of the backup
2170 superblock --- this usually means that the main superblock is
2174 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2175 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2176 revision level to the superblock.
2178 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
2185 * initialize.c: Completely revamped the inode and block bitmap
2186 structures, so that they can be better chance of being extensible
2187 in a shared library. They are now their own type, instead of
2188 being a char *. Also, the function signatures of
2189 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2190 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2191 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2192 changed to eliminate the ext2_filsys argument, since it is no
2195 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2197 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2198 system call if available.
2200 * llseek.c: new file. This is the stub calling the llseek system
2201 call which allows supports for 2GB+ file systems.
2203 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2204 the creator operating system.
2206 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2208 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2209 the group descriptor statistics in addition to everything else.
2210 This relieves mke2fs of the responsibility of doing it.
2212 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2213 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2214 not the generic C function equivalents should be included or not.
2216 * openfs.c (ext2fs_open): If a superblock is specified, then use
2217 the backup group descriptors that go along with this superblock,
2218 instead of using the primary group descriptors. This allows
2219 e2fsck to recover filesystems where the primary group descriptors
