1 2001-07-04 Theodore Tso <tytso@valinux.com>
3 * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set):
4 Add new functions (C and in i386 assembler) which quickly
5 find bits set in a bitmask.
7 2001-06-23 Theodore Tso <tytso@valinux.com>
9 * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files
10 ext2_ext_attr.h and ext_attr.c for extended attributes
13 * Release of E2fsprogs 1.22
15 2001-06-22 Theodore Tso <tytso@valinux.com>
17 * mkjournal.c (ext2fs_add_journal_inode): Move close of file
18 descriptor so that adding a journal to a mounted
19 filesystem doesn't die. (Fixes a bug accidentally
20 introduced in e2fsprogs 1.21.)
22 * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if
23 HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has
24 fchflags without defining UF_NODUMP. (Addresses Debian
27 * flushb.c: Use platform independent method of defining the
28 BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h
29 since on newer glibc's BLKFLSBUF is defined there.
31 * bitops.h: The C language versions of ext2fs_swab16/32 need to be
32 included if EXT2FS_ENABLE_SWAPFS is defined, since we need
33 to support byte swapping even if we don't support the
34 conversion functions. (Fixes Debian bug #101686).
36 * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2
37 since the byte-swapping code all assumes the
38 ext2_dir_entry structure. (It's a question of whether or
39 not name_len should be byte-swapped or not, and whether
40 it's a 16 bit or 8 bit field.)
42 2001-06-15 Theodore Tso <tytso@valinux.com>
44 * Release of E2fsprogs 1.21
46 2001-06-15 Theodore Tso <tytso@valinux.com>
48 * Makefile.in: Fix bug in installation of ext2_types.h. It is a
49 file which is generated and is therefore found in the
50 build directory, not source directory.
52 * ismounted.c (check_mntent_file): Use a test file in / to check
53 to see if the root filesystem is mounted read-only. This
54 protects against the case where /etc might not be on /, as
55 well as the case where /etc/mtab doesn't exist. (Both are
56 should-never happen scenarios, but you never know...)
58 2001-06-14 Theodore Tso <tytso@valinux.com>
60 * ismounted.c (ext2fs_check_if_mounted): Fix grammer in comment.
61 Remove unneeded #pragma argsused, since the arguments are
64 2001-06-13 Theodore Tso <tytso@valinux.com>
66 * ext2_types.h.in: If linux/types.h has been defined, then don't
67 try to redefine the typedefs.
69 * Makefile.in (HFILES): Add ext2_types.h to the list of files
70 which should be installed.
72 * ismounted.c (check_mntent_file): Work around GNU hurd brain
73 damage. Addresses Debian bug #100304.
75 * Makefile.in: Limit some .o files from being included into the
76 library if --disable-debugfs, --disable-swapfs,
77 --disable-imager, or --disable-resizer are used.
79 2001-06-12 Theodore Tso <tytso@valinux.com>
81 * inode.c, tst_iscan.c: Stop using the compatibility badblocks
82 function, and use the ext2fs_badblocks_* functions
85 2001-06-11 Theodore Tso <tytso@valinux.com>
87 * Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
88 ext2fs_mark_generic_bitmap and
89 ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
90 functions. (This saves space and doesn't significantly
91 change the speed of e2fsck on a P-III.)
93 * ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
94 inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
95 include the byte-swapping logic if ENABLE_SWAPFS is turned
96 on or if we're on a big-endian machine.
98 * initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
99 set EXT2_FLAG_SWAP_BYTES, instead of using
102 * native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
103 autoconf to determine whether or not return
104 EXT2_FLAG_SWAP_BYTES.
106 2001-06-10 Theodore Tso <tytso@valinux.com>
108 * Makefile.in: Remove the dependence on the libe2p library.
110 * mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
111 with direct usage of the ioctl/fchflags so that we don't
112 have to depend on the libe2p library.
114 2001-06-08 Theodore Tso <tytso@valinux.com>
116 * ext2_types.h.in: Use unsigned ints in favor of unsigned longs
117 when trying to find a 32-bit wide type.
119 * icount.c (insert_icount_el): Fix the code used to estimate the
120 size of the new icount array to be more intelligent, to
121 avoid reallocating the array too many times. Thanks to
122 Enrique Perez-Terron for pointing this out.
124 2001-06-02 Theodore Tso <tytso@valinux.com>
126 * valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
127 for a symlink to determine whether it is a fast symlink.
129 2001-06-01 Theodore Tso <tytso@valinux.com>
131 * Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
132 Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
134 2001-05-25 Theodore Tso <tytso@valinux.com>
136 * Release of E2fsprogs 1.20
138 2001-05-25 Theodore Tso <tytso@valinux.com>
140 * ismounted.c: More cleanups for ismounted.c, some from Andreas,
141 some to clean up Andreas's patches. Use strncpy instead
142 of strcpy to save the root's mountpoint. Clean up #ifdef
143 structure. Remove uneeded variable in testing/debug driver.
145 2001-05-24 Andreas Dilger <adilger@turbolinux.com>
147 * ismounted.c: Add check for root device which doesn't depend on
148 /etc/fstab or /proc/mounts to be correct. Don't call
149 endmntent() before we are done with mnt struct.
151 2001-05-23 Theodore Tso <tytso@valinux.com>
153 * ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
156 2001-05-21 Theodore Tso <tytso@valinux.com>
158 * ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
159 make room for pre-existing usage of
160 EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
161 the same codepoint as EXT2_BTREE_FL.
163 2001-05-20 Theodore Tso <tytso@valinux.com>
165 * ext2fs.h: #include <> instead of "" for ext2fs and et header
166 files, since they will be installed in /usr/include
168 2001-05-14 Theodore Tso <tytso@valinux.com>
170 * alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
171 bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
172 check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
173 dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,
174 expanddir.c, ext2_fs.h, fileio.c, finddev.c, flushb.c,
175 freefs.c, get_pathname.c, getsize.c, icount.c, imager.c,
176 initialize.c, inline.c, inode.c, irel_ma.c, ismounted.c,
177 link.c, lookup.c, mkdir.c, mkjournal.c, namei.c, native.c,
178 newdir.c, nt_io.c, openfs.c, read_bb.c, read_bb_file.c,
179 rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c,
180 tst_badblocks.c, tst_byteswap.c, tst_getsize.c,
181 tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
182 write_bb_file.c, ext2_fs.h: Moved file from include/linux.
183 Adjust all files in this directroy to include this file.
185 * mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
188 2001-05-05 Theodore Tso <tytso@valinux.com>
190 * fileio.c (ext2fs_file_read): Factored out common code and
191 cleaned up function. Fixed a bug where if there was an
192 error reading from the disk, the number of bytes read
193 wasn't reliably set. (Fixes Debian bug #79163)
194 (ext2fs_file_write): Factored out common code and made
195 function more efficient; if writing a full block, don't
196 bother to do a read-modify-write cycle.
198 2001-05-04 Theodore Tso <tytso@valinux.com>
200 * dirblock.c (ext2fs_read_dir_block): Check for an directory
201 record length which isn't a multiple four, and treat that
202 as an invalid. Scan the directory and return an error
203 (EXT2_ET_DIR_CORRUPTED) if the directory records are
205 (ext2fs_write_dir_block): If while byte-swapping the
206 directory block, if there's an error, abort and return
207 EXT2_ET_DIR_CORRUPTED.
209 2001-05-02 Theodore Tso <tytso@valinux.com>
211 * ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
212 image_header field in the ext2_filsys structure
214 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
215 * inode.c (ext2fs_read_inode):
216 * rw_bitmaps.c (read_bitmaps):
217 * openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
219 * imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
220 sure the full bitmap is saved.
222 2001-05-01 Theodore Tso <tytso@valinux.com>
224 * e2image.h (struct ext2_image_hdr): Add space for the device name
227 * dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
228 make sure the rec_len is a multiple of 4, to prevent
229 bus-errors on architectures which care about mis-aligned
232 2001-04-25 Theodore Tso <tytso@valinux.com>
234 * getsize.c (ext2fs_get_device_size): Use an unsigned long to
235 query the device sizes using the BLKGETSIZE ioctl.
237 2001-04-16 Theodore Tso <tytso@valinux.com>
239 * ismounted.c (check_mntent): Check /proc/mounts on Linux systems
240 before checking /etc/mtab. The EXT2_MF_READONLY flag is
241 now set from the /etc/mtab options field for all
242 filesystems, not just the root filesystem. Add debugging
243 code to make it easier to test ext2fs_check_if_mounted().
245 * mkjournal.c (ext2fs_create_journal_superblock): Add safety
246 check; return an error if there's an attempt to create a
247 journal less than 1024 filesystem blocks.
249 * ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
250 EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
252 2001-02-20 Theodore Tso <tytso@valinux.com>
254 * bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
257 * tst_byteswap.c: New function to test the byteswap functions.
258 Add to regression test suite.
260 2001-02-08 Theodore Tso <tytso@valinux.com>
262 * e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
264 2001-02-07 Theodore Tso <tytso@valinux.com>
266 * mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
267 of s_first for external devices to always be 1, since
268 jsb->s_first is always relative to the start of the
269 journal superblock. Use htonl(1) when setting s_nr_users.
271 2001-01-17 Theodore Ts'o <tytso@valinux.com>
273 * mkjournal.c (ext2fs_add_journal_device): Fix bug where the
274 device number of the filesystem (instead of the journal)
275 was being dropped into s_journal_dev.
277 2001-01-15 Theodore Ts'o <tytso@valinux.com>
279 * initialize.c (ext2fs_initialize): Add support for initializing
280 the ext2 superblock for external journal devices. This
281 basically means we don't bother to allocate any block
284 * openfs.c (ext2fs_open): Only open external journal devices if
285 the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
286 ext2fs_open. When opening such devices, don't try to read
287 the block group descriptors, since they're not there.
289 * ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
291 * mkjournal.c: Export a new function,
292 ext2fs_create_journal_superblock(), which allocates and
293 returns a buffer containing a journal superblock. This is
294 needed by mke2fs to create an external journal. Rewrote
295 ext2fs_add_journal_device() so that it no longer creates
296 the external journal, but rather adds a filesystem to an
297 existing external journal. It handles all of the UUID
300 * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
301 by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
302 Changed function prototype for ext2fs_add_journal_device().
304 2001-01-14 Theodore Ts'o <tytso@valinux.com>
306 * closefs.c (ext2fs_flush): Don't write out anything beyond the
307 primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
310 2001-01-12 Theodore Ts'o <tytso@valinux.com>
312 * imager.c: Fix gcc -Wall complaints and a series of bugs where
313 retval wasn't set correctly. (Thanks to Andreas Dilger
314 for pointing this out.)
316 2001-01-11 <tytso@snap.thunk.org>
318 * flushb.c (ext2fs_sync_device): New function which centralizes
319 all of the places which might try to use the BLKFLSBUF
320 or FDFLUSH ioctls (and usually failing to define them
321 since the system header files don't usually do this for
322 us, and we're trying to avoid usage of kernel include
325 2001-01-10 <tytso@snap.thunk.org>
327 * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
328 bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
329 dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
330 finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
331 irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
332 mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
333 tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
334 ext2_ino_t, to protect applications that attempt to
335 compile -D_FILE_OFFSET_BITS=64, since this inexplicably
336 changes ino_t(!?). So we use ext2_ino_t to avoid an
337 unexpected ABI change.
339 2001-01-05 <tytso@snap.thunk.org>
341 * dirblock.c (ext2fs_read_dir_block): Fix a potential case where
342 we may overrun allocated memory in case of a corrupted
343 filesystem (or an e2fsck test case :-) when byte-swapping
346 * ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
348 * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
349 complaints including a missing return 0 at the end of
350 ext2fs_add_journal_device.
352 2001-01-03 <tytso@snap.thunk.org>
354 * Makefile.in: Link in libe2p when creating libext2fs as a shared
355 library, since mkjournal.c now references fsetflags().
357 * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
358 Dilger's changes (with fixups) to allow on-line creation
361 * ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
362 EXT2_FLAG_SUPER_ONLY, which the close routines to only
363 update the superblock, and not the group descriptors.
365 2000-12-30 Andreas Dilger <adilger@turbolinux.com>
367 * ismounted.c: add ext2fs_check_mount_point() function, which will
368 optionally return the mount point of a device if mounted
370 2000-12-14 Andreas Dilger <adilger@turbolinux.com>
372 * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
373 ext2fs_add_journal_inode()
375 2001-01-01 <tytso@snap.thunk.org>
377 * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
378 source (but not binary) compatibility of some users of the
379 ext2 library. They should just simply do a global search
380 and replace of struct ext2fs_sb with struct
381 ext2_super_block, and use their own private copy of
382 ext2_fs.h if they aren't already.
384 * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
385 Replace use of ext2fs_sb with ext2_super_block.
387 2000-12-31 <tytso@snap.thunk.org>
389 * ext2fs.h: Cleaned up header file by removing definitions of
390 feature flags that might not have been defined in older
391 ext2 header files. Now that we're using our own
392 include/linux/ext2fs.h header file, this can never happen.
394 * jfs_dat.h: Removed old header file which is no longer needed.
396 2000-12-13 Theodore Ts'o <tytso@valinux.com>
398 * closefs.c (ext2fs_update_dynamic_rev): New function suggested
399 by Andreas Dilger to update the filesystem revision to
402 * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
405 2000-12-09 <tytso@snap.thunk.org>
407 * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
408 ext2fs_add_journal_device): Add a new argument to the APIs
409 of these function, which is a flags word. This is used to
410 allow the creation of a V1 superblock for those folks who
411 are using ext3 0.3b in production. Note, the user-land
412 interface for getting at this flag won't be documented, as
413 the V1 superblock is deprecated.
415 * mkjournal.c (init_journal_superblock): Sync Stephen's changes
416 which creates a V2 superblock instead of a V1 superblock.
418 2000-11-21 <tytso@snap.thunk.org>
420 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed
421 out by Andreas Dilger.
423 2000-11-05 <tytso@snap.thunk.org>
425 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
426 ext2_fs.h, Makefile.in: New file that has routines that
427 save ext2fs metadata to a file.
429 * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
431 * e2image.h: New file which defines the file format for the ext2
432 image file. (Saved copy of ext2 metadata to a file as a
433 saving throw against worst-case damage.)
435 2000-11-01 <tytso@snap.thunk.org>
437 * inode.c (ext2fs_flush_icache): Add new function
438 ext2fs_flush_icache() which flushes the internal inode
439 cache. Applications which modify the inode table blocks
440 directly must call this function.
442 2000-10-26 <tytso@snap.thunk.org>
444 * mkjournal.c: Add #include of netinet/in.h, since Solaris
445 requires it for ntohl().
447 * ext2_io.h (io_channel_write_byte): Add new interface to allow
448 callers to write specific byte ranges. This is an
449 optional interface, which not all IO channels may
452 * unix_io.c (unix_write_byte):
453 * test_io.c (test_write_byte): Add implementation of the
456 * closefs.c (write_primary_superblock, ext2fs_flush): Add a new
457 function which writes the primary superblock. If the IO
458 channel supports writing raw bytes directly, only fields
459 which were modified are written to the disk. This makes
460 it safe(r) to use utilities like tune2fs on a mounted
463 * freefs.c (ext2fs_free): Free the original superblock if it is
466 * openfs.c (ext2fs_open): Store a copy of the original superblock
469 * ext2fs.h: Add a field to store the original superblock in the
470 ext2 context structure.
472 2000-10-24 <tytso@snap.thunk.org>
474 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
475 don't need to use llseek).
477 2000-10-24 <tytso@valinux.com>
479 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
480 creating an ext3 journal on a filesystem.
482 2000-08-21 <tytso@valinux.com>
484 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
486 2000-08-22 <tytso@valinux.com>
488 * unix_io.c: Make massive changes to support a multiple block
489 writethrough cacheing.
491 * ext2_io.h: Added flags field to the io_channel structure.
493 2000-08-19 <tytso@valinux.com>
495 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
496 provides the function ext2fs_find_block_device(). This
497 function returns the pathname to a block device, given its
500 2000-07-13 <tytso@valinux.com>
502 * Release of E2fsprogs 1.19
504 2000-07-07 Theodore Ts'o <tytso@valinux.com>
506 * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
507 EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
508 list of filesystem flags supported by the library.
510 2000-07-04 Theodore Ts'o <tytso@valinux.com>
512 * ext2fs.h: Update to include latest journalling additions to the
515 * dll/jump.funcs: Add new jumptable entries for
516 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
517 ext2fs_badblocks_equal.
519 * tst_badblocks.c: Update test program to test
520 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
522 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
523 writes out bad blocks list to a file.
525 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
526 changes the callback function to take two additional
527 arguments; a private blind pointer supplied by the caller,
528 and pointer to a char * containing a pointer to the
531 * badblocks.c (ext2fs_badblocks_equal): Add new function which
532 returns true if two badblocks list are equal.
534 * Makefile.in: Remove explicit link of -lc in the shared library.
535 (It shouldn't be necessary, and is harmful in some cases).
537 2000-06-10 Theodore Ts'o <tytso@valinux.com>
539 * getsize.c (main): Add debugging code under #ifdef DEBUG
541 2000-05-27 Theodore Ts'o <tytso@valinux.com>
543 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
544 earlier, so that if there's an error reading it, we can
545 more cleanly back out of the operation.
547 2000-05-25 <tytso@snap.thunk.org>
549 * getsize.c (ext2fs_get_device_size): Use open64() instead of
550 open() if it exists. Under linux, manually define the
551 ioctl for BLKGETSIZE if it isn't already defined and it's
554 * unix_io.c (unix_open): Use open64() instead of open() if it
557 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
558 available (and prototypes are defined) use it in
559 preference to llseek.
561 * Makefile: Add hack dependency rule so that parallel makes work
564 2000-05-18 Theodore Ts'o <tytso@valinux.com>
566 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
568 2000-04-03 Theodore Ts'o <tytso@valinux.com>
570 * block.c: Readibility tweak in conditionals involving
573 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
574 how to define __s64 and __u64. Turn off "compression is
575 experimental" warning if the cpp macro
576 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
578 2000-02-11 <tytso@snap.thunk.org>
580 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
581 Conditionally include Compression as a supported type if
582 ENABLE_COMPRESSION (via --enable-compression) is turned on.
584 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
586 2000-02-08 <tytso@snap.thunk.org>
588 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
589 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
590 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
591 Change to return the previous state of the bit that is
592 being marked or unmarked. For speed optimization.
594 2000-02-02 Theodore Ts'o <tytso@valinux.com>
596 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
598 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
599 needed any more; we know it will always be i_generation.
600 Add support for swapping the high bits of the uid and gid.
602 1999-11-19 <tytso@valinux.com>
604 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link

609 the source directory.
611 1999-11-10 <tytso@valinux.com>
613 * Release of E2fsprogs 1.18
615 1999-11-08 <tytso@valinux.com>
617 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
618 since ext2fs_badblocks_list_free was moved to freefs.c.
620 * tst_badblocks.c: Use the newer badblocks API names. Add
621 duplicate blocks to the test inputs to test dealing with
622 adding blocks which are already in the badblocks list.
624 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
625 of the list, use a shortcut O(1) operations instead of an
626 O(n) operation. (Idea suggested by David Beattie.)
628 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
629 of badblocks_list_free(), to save a procedure call.
631 1999-10-26 <tytso@valinux.com>
633 * Release of E2fsprogs 1.17
635 1999-10-26 <tytso@valinux.com>
637 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
638 seem to handle ~0UL the same way as they used to.
640 1999-10-25 <tytso@valinux.com>
642 * nt_io.c (_OpenNtName): Open the device using
643 FILE_SYNCHRONOUS_IO_NONALERT instead of
644 FILE_SYNCHRONOUS_IO_ALERT
645 (nt_open): At the end of the device open routine, unlock
646 the drive but do not dismount it.
648 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
651 1999-10-22 <tytso@valinux.com>
653 * Release of E2fsprogs 1.16
655 1999-10-22 <tytso@valinux.com>
657 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
659 * link.c (ext2fs_link): This call now uses the low three bits of
660 the flags parameter to pass the directory filetype
661 information; it will set the directory entry FILETYPE
662 information if the filesystem supports it.
664 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
665 option is set, then create the '.' and '..' entries with
666 the filetype set to EXT2_FT_DIR.
668 1999-09-24 <tytso@valinux.com>
670 * nt_io.c: New file which supports I/O under Windows NT.
672 1999-09-07 <tytso@valinux.com>
674 * ext2fs.h: Add new fields for journalling and define new
675 feature bits used by newer filesystems: IMAGIC_INODES,
676 HAS_JOURNAL, RECOVER.
678 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
679 we update the inode block count and size files so that the
680 block count field is updated correctly when we create an
683 1999-07-18 Theodore Ts'o <tytso@valinux.com>
685 * Release of E2fsprogs 1.15
687 1999-06-23 <tytso@valinux.com>
689 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
690 kernels that use i_generation instead of i_version. Patch
691 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
693 1999-06-21 <tytso@valinux.com>
695 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
696 directory entry before calling the callback function.
697 This should prevent some core dumps of insufficiently
698 paranoid callback functions.
700 1999-05-29 <tytso@rsts-11.mit.edu>
702 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
704 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
705 that we don't handle writing yet (we do). Fixed bug where
706 we weren't allocating a big enough buffer for ext2_bmap.
708 1999-05-03 <tytso@rsts-11.mit.edu>
710 * openfs.c (ext2fs_open): Check to make sure that the number of
711 blocks per group is not zero --- if so, it must be a bad
714 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
716 * Release of E2fsprogs 1.14
718 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
720 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
721 the inode number is zero; if it's zero, return
722 EXT2_ET_BAD_INODE_NUM.
724 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
726 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
727 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
730 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
732 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
733 non-Linux case to use EINVAL by default, unless it isn't
734 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
737 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
739 * Release of E2fsprogs 1.13
741 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
743 * Makefile.in: Updated dependencies.
745 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
747 * initialize.c (ext2fs_initialize): Make sure that we allocate
748 enough inodes so that we can make a valid filesystem.
750 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
752 * rw_bitmaps.c: Fixed signed/unsigned warnings.
754 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
755 function declaration.
757 * dblist.c (make_dblist): Add safety check in case the dblist
758 pointer passed in is null (in which case, assign it to
759 fs->dblist). Fixed some signed/unsigned warnings.
761 * bmap.c: Make addr_per_block be of type blk_t to avoid
762 signed/unsigned warnings.
764 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
765 function declaration.
767 * get_pathname.c (get_pathname_proc): Use return value from
768 ext2fs_get_mem, instead of checking if &gp->name is

772 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
773 from the function declaration.
775 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
776 return the error directly instead of jumping to the
777 cleanup routine, since we don't need to do any cleanup.
779 * alloc_table.c (ext2fs_allocate_group_table): Make this
780 function take a dgrp_t for its group argument.
782 * ext2fs.h: Make dgrp_t an __u32 type, and make
783 fs->desc_group_count be of type dgrp_t.
785 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
787 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
788 than 10 blocks when we need to expand the size of the
791 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
793 * Release of E2fsprogs 1.12
795 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
797 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
798 appropriate for all of the block group copies, so that
799 it's clear where the beginning of the filesystem is on the
800 disk. (For when the partition table gets scrod.)
802 * ext2fs.h: Change the name of the feature from
803 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
804 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
806 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
808 * inode.c (get_next_blockgroup): Fix bug where if
809 get_next_blockgroup() is called early because of a missing
810 inode table in a block group, the current_inode counter
811 wasn't incremented correctly.
813 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
815 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
816 against a completely trashed bad block inode.
818 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
820 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
821 the stride length hits a bad value, we retry the block
822 allocation starting at the beginning of the block group.
824 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
825 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
826 e2_blkcnt_t to avoid collision with LFS API.
828 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
830 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
831 way that avoids overflows on disk sizes greater than 4GB.
833 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
835 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
836 return type for comparison functions for qsort.
838 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
841 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
843 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
846 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
847 evade a potential problem with glibc's header files trying
848 to spike out linux/types.h.
850 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
851 include the old size of the memory, which is needed for
852 some braindamaged memory allocation systems that don't
855 * badblocks.c (ext2fs_badblocks_list_add):
856 bb_inode.c (clear_bad_block_proc):
857 dblist.c (ext2fs_add_dir_block):
858 icount.c (insert_icount_el):
860 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
861 pass the old size of the memory to be resized to
864 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>

867 convention. Fix uninstall rules to take $(DESTDIR) into
870 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
872 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
873 with 32 bit longs, then we need to manually define __s64
874 and __u64, since the current kernel header files don't
875 define these if __STRICT_ANSI__ is defined. This is a
876 problem if we are compiling with full GCC warnings, since
877 we do need 64 bit support.
879 * Makefile.in (OBJS): Remove bmove.o from files to be built,
880 since we're not using ext2fs_move_blocks() and there
881 is some question as to its usefulness in its current
884 * bmap.c (block_bmap): Remove unused function.
886 * bmove.c (process_block): Fix -Wall warning.
888 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
890 * block.c (ext2fs_block_iterate3): Make the ref_offset field
891 contain the offset into the inode.i_blocks array when
892 ref_block is zero. Since we haven't done a formal
893 release of e2fsprogs since block_iterate2 was first
894 introduced, I removed block_iterate2, and renamed
895 block_iterate3 to be block_iterate2.
897 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
898 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
899 use of block_iterate and block_iterate2 to
900 block_iterate2 with the new prototype for the
901 interator function. (using blkcnt_t forr blockcount)
903 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
905 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
906 s_prealloc_blocks, s_prealloc_dir_blocks). Added
907 conditional defines of new features COMPAT_DIR_PREALLOC,
908 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
909 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
910 the library to declare that we support COMPAT_DIR_PREALLOC,
911 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
913 * fileio.c: Rename function ext2fs_file_llseek to be
914 ext2fs_file_lseek, which is more accurate.
916 * block.c: Add new function ext2fs_block_iterate3 which calls
917 the iterator function with the blockcount argument of
918 type blkcnt_t. This version of the function is
919 allowed to handle large files; the other fucntions are
922 * ext2fs.h: Add new type blkcnt_t
924 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
926 * block.c (ext2fs_block_iterate2): Fix bug where the block count
927 field wasn't getting correctly incremented for sparse
928 files when the indirect or doubly-indirect block
929 specified in the inode was zero.
931 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
933 * unlink.c (unlink_proc):
934 * lookup.c (lookup_proc):
935 * link.c (link_proc):
936 * get_pathname.c (get_pathname_proc):
937 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
938 from dirent->name_len, so it can be used for other
941 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
942 and indicate that we have support for this incompatible
945 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
947 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

951 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
952 number of directories when the block group information is
955 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
957 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
958 inode table is missing so that we catch the case where the
959 first block group is missing.
961 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
964 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
966 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
968 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
970 * test_io.c (test_flush): Add a debugging printf when the flush
973 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
974 read in, return right away.
976 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
978 * bitops.h: Don't try to do i386 inline asm functions if the
981 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
982 instead of linux/types.h, and e2_bitops.h instead of
985 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
988 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
990 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
991 so that we don't need to call get_next_blockgroup() the
992 first time around. Saves a bit of time, and prevents us
993 from needing to assign -1 to current_group (which is an
996 * icount.c (insert_icount_el): Cast the estimated number of inodes
997 from a float to an ino_t.
999 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

1010 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
1011 defined, then assume all of the
1012 ext2-specific header files are in a flat directory.
1014 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
1015 all assignments from void * to be compatible with C++.

1022 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1024 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
1025 avoid C++ namespace clash.

1036 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1038 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
1039 paranoid about validating the directory counts from the
1040 block group information.
1042 * all files: Don't include stdlib.h anymore; include it in
1043 ext2_fs.h, since that file requires stdlib.h
1045 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1047 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
1048 bitmap is loaded, and return an error if it is not.
1049 (expand_dir_proc): Only use ext2fs_write_dir_block when
1050 writing a directory block, not when writing out a fresh
1053 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1077 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1079 * [all files, basically]: Added definition of ext2fs_get_mem,
1080 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
1081 changed all library routines to use these wrapper functions.
1083 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
1084 instead of the system error messages.
1086 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
1089 * ext2fs.h: Added function declarations and constants for bmap.c
1092 * ext2_err.et.in: Added new error messages EXT2_FILE_RO and
1093 EXT2_ET_MAGIC_EXT2_FILE
1095 * Makefile.in: Added files bmap.c and fileio.c, and temporarily
1096 commented out brel_ma.c and irel_ma.c
1098 * bmap.c: New file which maps a file's logical block number to its
1099 physical block number.
1101 * fileio.c: New file which implements simple file reading and
1104 * alloc.c (ext2fs_alloc_block): New function which allocates a
1105 block, zeros it, and updates the filesystem accounting
1106 records appropriately.
1108 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1110 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
1111 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
1112 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
1114 * Change various library files to use these functions instead of
1115 EINVAL, ENOENT, etc.
1117 Mon Oct 20 19:32:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1119 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
1120 need to declare llseek().
1122 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1124 * Rename io.h to be ext2_io.h (avoid namespace collisions)
1126 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
1128 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1162 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1164 * io.h: Change the prototype of ext2fs_llseek() to use int's
1165 instead of unsigned int's.
1167 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
1168 to make life easer for GNU Libc 2.
1170 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
1171 filesystem has its bitmaps stored as 32-bit words with bit
1172 0 as the LSB of each word. Thus a bitmap with only bit 0
1173 set would be, as a string of bytes, 00 00 00 01 00 ... To
1174 cope with this, we byte-reverse each word of a bitmap if
1175 we have a big-endian filesystem, that is, if we are *not*
1176 byte-swapping other word-sized numbers.
1178 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

1196 and size_t where appropriate.
1198 * closefs.c (ext2fs_flush): Use dgrp_t instead of int where
1201 * openfs.c (ext2fs_open):
1202 * check_desc.c (ext2fs_check_desc): Use blk_t instead of int where

1208 * initialize.c (ext2fs_initialize):
1209 * brel_ma.c: Fix to make be 16-bit safe.
1211 * link.c (ext2fs_link):
1212 * unlink.c (ext2fs_unlink):

1225 * bb_inode.c (set_bad_block_proc): Add #pragma argsused for Turbo C.
1227 * alloc.c (ext2fs_new_inode): Use ino_t instead of int for the
1230 * get_pathname.c: Use ino_t instead of int where appropriate.
1232 * ext2fs.h: Make the magic structure element be errcode_t instead
1235 * alloc.c alloc_tables.c badblocks.c bb_compat.c bb_inode.c
1236 bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c
1237 cmp_bitmaps.c dblist.c dblist_dir.c dir_iterate.c
1238 dirblock.c dupfs.c expanddir.c freefs.c get_pathname.c
1239 icount.c initialize.c inline.c inode.c irel_ma.c link.c
1240 llseek.c lookup.c mkdir.c namei.c newdir.c read_bb.c
1241 read_bb_file.c rs_bitmap.c rw_bitmaps.c swapfs.c
1242 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
1243 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
1245 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1247 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
1248 is zero, then return EXT2_IO_LLSEEK_FAILED.
1250 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
1252 * Release of E2fsprogs 1.11
1254 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1256 * dblist.c (ext2fs_dblist_count): Added new function which returns
1257 the number of directory blocks in dblist.
1259 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1261 * unix_io.c (unix_flush): Make the io_channel flush function do a
1262 fsync to flush the kernel buffers to disk.
1264 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1266 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
1267 current inode number wasn't being set by the
1268 goto_blockgroup function.
1270 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1272 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
1273 of blocks which need to be moved, and moves those blocks
1274 to another location in the filesystem.
1276 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
1277 bitmap, make sure all of the new parts of the bitmap are
1280 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1282 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
1283 wasn't being returned to the caller.
1285 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
1286 ext2fs_allocate_group_table() which sets the group tables
1287 for a particular block group. The relevant code was
1288 factored out of ext2fs_allocate_tables().
1290 * dblist.c (make_dblist): Adjust the initial size of the directory
1291 block list to be a bit more realistic (ten plus twice the
1292 number of directories in the filesystem).
1294 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1296 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
1297 ext2fs_badblocks_list_test would test the list (and exceed
1298 array boundaries) if there were no bad blocks on the bad
1299 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
1301 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1303 * Release of E2fsprogs version 1.10
1305 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1307 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
1308 inode and block bitmaps based on the RAID 0 stride
1309 parameter (which is passed by mke2fs).
1311 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
1312 mke2fs to communicate the stride length to
1313 ext2fs_allocate_tables()
1315 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1317 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
1318 systems. (We can't assume that the new filesystem types
1321 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1323 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
1324 allocate the inode and block bitmaps inside block group at
1327 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1329 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
1330 filesystem has no free blocks, ext2fs_new_block would loop
1333 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
1335 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
1336 free if refcount goes to zero.
1338 * inode.c (create_icache): Initialize refcount to 1.
1340 * ext2fsP.h: Added refcount to ext2_inode_cache
1342 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
1345 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
1346 badblocks structure.
1348 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1350 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
1352 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
1354 (unix_close, test_close): Decrement the refcount and only
1355 close the io_channel if the refcount goes to 0.
1357 * io.h: Add refcount to the io_channel structure. Add new macro
1358 interface io_channel_bumpcount() to bump the refcount.
1360 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1362 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
1363 cache in the filesystem handle, instead of the inode cache
1364 in a static variable.
1366 * freefs.c: Added static function to free the inode cache (called by
1369 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
1371 * ext2fs.h: Added pointer to the inode_cache structure.
1373 * block.c (block_iterate_ind, block_iterate_dind,
1374 block_iterate_tind): If there are holes in the indirect,
1375 doubly indirect, or triply indirect blocks, increment the
1376 block count field automatically.
1378 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1380 * Release of E2fsprogs version 1.09
1382 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1384 * version.c (ext2fs_parse_version_string): Check the passed in
1385 version string (instead of the hard-coded one).
1387 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
1388 greater filesystem size, clamp it to prevent allocating a
1389 block or inode bitmap beyond the filesystem.
1391 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
1392 overhead calculation was accidentally removed.
1394 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1396 * Release of E2fsprogs version 1.08
1398 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1400 * dblist.c (ext2fs_set_dir_block): New function which sets the
1401 block of a dblist entry, given the directory inode and
1404 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1406 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
1407 inode bitmaps at staggered locations across the block
1408 groups, to avoid concentrating the bitmaps on a small
1409 number of disks when using striped RAID arrays.
1411 * initialize.c (ext2fs_initialize): By default, choose the maximum
1412 possible number of blocks per group (based on the size of
1413 the bitmaps in the blocksize).
1415 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1417 * initialize.c (ext2fs_initialize): Add support for
1418 EXT2_COMPAT_SPARSE_SUPER feature.
1420 * closefs.c (ext2fs_bg_has_super): New function to determine
1421 whether or a particular block group should have a
1422 superblock and block group descriptor. Used for the
1423 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
1424 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
1425 or not the superblock should be written out for the block
1428 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
1429 for sparse duplicate superblocks.
1431 * version.c (ext2fs_get_library_version): New function which
1432 returns the library version.
1434 * version.c (ext2fs_parse_version_string): New function which
1435 parses a version string and returns a version number,
1436 so application programs can compare version numbers as
1439 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1441 * icount.c (ext2fs_create_icount): Change function so that it also
1442 takes a new argument which contains a "hint" icount
1443 structure. This "hint" icount allows the create function
1444 to set up the sorted list in advance. This reduces
1445 significantly the amount of data moving needed to insert
1446 these inodes into the list later.
1448 * icount.c (ext2fs_icount_validate): New function which validates
1449 that the icount structure's rep invariant.
1451 * icount.c (get_icount_el): Completely revamped implementation
1452 to subsume put_icount_el(). Put_icount_el() used to
1453 use an O(N) implementation to insert in the middle
1454 of the icount list. It now uses a O(ln N) to search
1455 for where the icount should be inserted, and then uses
1456 a memcpy to move the list down (instead of a for loop).
1458 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
1459 ext2fs_icount_increment, ext2fs_icount_decrement): Check
1460 to see if the inode is within bounds; if it isn't, return
1463 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
1464 when a bad inode number is passed to test_generic_bitmap
1465 to be EXT2FS_TEST_ERROR instead of the wrong
1466 EXT2FS_UNMARK_ERROR.
1468 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1470 * Release of E2fsprogs version 1.07
1472 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1474 * Makefile.in (ELF_VERSION): Change version to be 2.2
1476 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1478 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1479 ext2fs_fast_test_block_bitmap_range().
1481 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1482 ext2fs_test_block_bitmap_range: New inline functions which
1483 test to see whether a contiguous range of blocks is
1486 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1488 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1489 use ext2fs_badblocks_* instead of badblocks_*
1491 * bb_compat.c: New file which translates between old badblocks_*()
1492 names to ext2fs_badblocks_*()
1494 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1495 link.c (since e2fsck doesn't use ext2fs_unlink()).
1497 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1498 bitmap resizing routine moved from bitmaps.c, since e2fsck
1499 doesn't need to use this function.
1501 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1502 since e2fsck only needs ext2fs_lookup.
1504 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1506 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1507 already set; this is needed so that programs like dump
1508 which use the inode scan functions will deal with
1509 filesystems that have bad blocks in the inode table.
1511 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1513 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1514 Moved to ext2fsP.h, since it doesn't need to be part of
1515 the public interface.
1517 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1519 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1521 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1522 directory block list abstraction. (Code moved from
1525 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1526 to inode.c (since no one else should be peeking inside it!)
1528 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1530 * openfs.c (ext2fs_open): Check the feature set in the ext2
1531 superblock, and refuse to open filesystems if they contain
1532 incompatible features. (Can be overriden with the
1535 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1537 * block.c (ext2fs_block_iterate2): Added new function
1538 ext2fs_block_iterate2 which changes the function
1539 signature of the callback function to include the
1540 referencing block and offset.
1542 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1543 ext2fs_inode_scan_goto_blockgroup which allows an
1544 application to jump to a particular block group while
1545 doing an inode scan.
1547 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1549 * dirblock.c: Include string.h, since we use memcpy().
1551 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1553 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1554 a long not an int; this doesn't matter on i386 machines,
1555 but it does on Alpha's.
1557 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1559 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1560 table pointer is NULL, then return an error indicating
1561 that the inode table is missing.
1562 (get_next_blockgroup, get_next_blocks,
1563 ext2fs_get_next_inode): Don't treat a missing inode table
1564 as permanent error. Return MISSING_INODE_TABLE, but as an
1565 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1567 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1568 ext2fs_write_inode_bitmap): If the inode or block bitmap
1569 block is zero, then don't write out the inode or block
1570 bitmap. The idea here is to avoid stomping on the
1572 (read_bitmaps): If the inode or block bitmap block is
1573 zero, then fill in that portion of the inode or block
1574 bitmap with all zeros.
1576 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1577 blocks in inode table when the inode table size is
1578 non-standard (and can therefore span blocks).
1580 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1582 * alloc.c (ext2fs_new_block): Fix fencepost error in

1588 * inode.c (check_for_inode_bad_blocks): New function called by
1589 get_next_blocks() to avoid reading in bad blocks marked in
1590 fs->badblocks. Inodes located in bad blocks are returned
1591 by ext2fs_get_next_inode() returns the error code
1592 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1594 * alloc_tables.c (ext2fs_allocate_tables): New function which
1595 performs the part of mke2fs's job of allocating the

1610 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1611 blocks to the badblock list in sorted order. This allows
1612 badblocks_list_test to be coded using a binary search for

1666 * namei.c (ext2fs_follow_link): New function.
1667 (ext2fs_namei): Extended to have support for chasing
1668 symbolic links. ext2fs_namei() still returns an inode
1669 which is a symbolic link. Symbolic links are only chased
1670 while resolving the containing directory. To chase
1671 symbolic links of the final result, use
1672 ext2fs_follow_link().

1683 * initialize.c (ext2fs_initialize): On systems where the byte
1684 order is not i386 compatible, set the swap_byte flag.
1686 * inode.c (inocpy_with_swap): Check to see if inode contains a
1687 fast symlink before swapping the inode block fields. This
1688 required adding a new argument to inocpy_with_swap to
1689 determine whether the mode field is in host order or not.
1691 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1693 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On

1720 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1722 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1723 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1724 that's a basic value that must be correct for the rest of
1725 the library to work.
1727 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1730 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1780 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1781 to avoid conflicts with with kernel include files. Also
1782 rename ADDR and CONST_ADDR to EXT2FS_ADDR and

1839 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1840 Move these functions to freefs.c.
1842 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1843 descriptors shadow memory to keep purify quiet. (This
1844 also has the nice benefit that the unused portion of the
1845 shadow descriptors are zeroed out.)
1847 * dirblock.c (ext2fs_write_dir_block): We need to use
1848 dirent->rec_len *before* it's byteswapped to find the
1849 location of the next directory structure!
1851 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1852 cause ext2fs_new_inode to loop infinitely if we're trying
1853 to allocate an inode in group #0 and there are no free
1854 inodes at all in the system.
1856 * closefs.c: #include <errno.h> if it exists.
1858 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

1890 the superblock and group descriptors before writing it out.
1892 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1893 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1894 and group descriptors.
1896 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1897 to desp ext2 filesystem structures.
1899 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1900 supplied by Pete A. Zaitcev so that the C language
1901 versions of these functions are more portable. They will
1902 now work on both little and big endian systems, and the
1903 assumption that 32-bit integers are used is gone.
1905 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1906 doing byte swapping.
1908 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

1922 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1923 if the magic number is correct, it will be allocated.
1925 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1927 * block.c (block_iterate_ind, block_iterate_dind,
1928 block_iterate_tind): Don't recompute block_nr each loop;
1929 just increment it! Factor check of BLOCK_FLAG_APPEND out
1930 of the loop. Factor mask of BLOCK_CHANGED into changed
1931 variable out of the loop. (block_iterate_ind, in
1932 particular, gets called a lot, so every little
1933 optimization helps.)
1935 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1937 * block.c (block_iterate_ind, block_iterate_dind,

1949 ext2fs_get_inode_bitmap_end): Add new accessor functions
1950 which return the start and end points of the bitmaps.
1952 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1954 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1955 instead of llseek. The errno if the offset is too large
1956 and lseek is not supported should be EINVAL, not -EINVAL.
1958 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1960 * Makefile.in: Added support for ELF shared libraries.
1961 Fixed typos in the compilation rules.

1976 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1977 the S_*, which are normally defined in <sys/stat.h>. This
1978 allows us to compile e2fsprogs on a non-Linux system,
1979 which may have a different value for S_IFDIR.
1981 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1983 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1984 this is a user-mode application!
1986 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1988 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1989 __linux__ so that non-linux systems won't see it.
1991 * alloc.c: Include <errno.h> if possible.
1992 * badblocks.c: Ditto.
1993 * bb_inode.c: Ditto.

2013 * initialize.c (ext2fs_initialize): Don't allow more than one
2014 bitmaps's worth of inodes in a group.

2018 * llseek.c (ext2_llseek): Added error checking to the llseek()
2019 compat code to protect against overflow. This only
2020 applies to 1.0 and early 1.1 kernels, which don't support
2021 the llseek() system call.
2023 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
2025 * unix_io.c (unix_open): Initialize the read_error and write_error
2026 io_channel pointers to be null.
2028 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
2029 found, clear it but don't try to update the filesystem
2030 accounting information, since that's hopeless anyway.
2032 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
2033 bloblock_iterate_tind): Check to see if the indirect blocks are
2034 valid before trying to read them.

2040 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
2041 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
2042 illegal block or inode number is passed in, return instead
2043 of trying to test, set, or clear the bit.

2104 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
2109 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
2110 openfs.c into its own file.
2112 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
2113 structure magic numbers.
2115 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
2116 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
2117 someone uses the -b option to specify the use of the backup
2118 superblock --- this usually means that the main superblock is
2122 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
2123 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
2124 revision level to the superblock.

2133 * initialize.c: Completely revamped the inode and block bitmap
2134 structures, so that they can be better chance of being extensible
2135 in a shared library. They are now their own type, instead of
2136 being a char *. Also, the function signatures of
2137 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
2138 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
2139 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
2140 changed to eliminate the ext2_filsys argument, since it is no
2143 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
2145 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
2146 system call if available.
2148 * llseek.c: new file. This is the stub calling the llseek system
2149 call which allows supports for 2GB+ file systems.
2151 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
2152 the creator operating system.
2154 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
2156 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
2157 the group descriptor statistics in addition to everything else.
2158 This relieves mke2fs of the responsibility of doing it.
2160 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
2161 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
2162 not the generic C function equivalents should be included or not.
2164 * openfs.c (ext2fs_open): If a superblock is specified, then use
2165 the backup group descriptors that go along with this superblock,
2166 instead of using the primary group descriptors. This allows
2167 e2fsck to recover filesystems where the primary group descriptors
