63 * io.h: Change the prototype of ext2fs_llseek() to use int's
64 instead of unsigned int's.
66 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
67 to make life easer for GNU Libc 2.
69 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
70 filesystem has its bitmaps stored as 32-bit words with bit
71 0 as the LSB of each word. Thus a bitmap with only bit 0
72 set would be, as a string of bytes, 00 00 00 01 00 ... To
73 cope with this, we byte-reverse each word of a bitmap if
74 we have a big-endian filesystem, that is, if we are *not*
75 byte-swapping other word-sized numbers.
77 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

139 llseek.c lookup.c mkdir.c namei.c newdir.c read_bb.c
140 read_bb_file.c rs_bitmap.c rw_bitmaps.c swapfs.c
141 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
142 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
144 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
146 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
147 is zero, then return EXT2_IO_LLSEEK_FAILED.
149 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
151 * Release of E2fsprogs 1.11
153 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
155 * dblist.c (ext2fs_dblist_count): Added new function which returns
156 the number of directory blocks in dblist.
158 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
160 * unix_io.c (unix_flush): Make the io_channel flush function do a
161 fsync to flush the kernel buffers to disk.
163 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
165 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
166 current inode number wasn't being set by the
167 goto_blockgroup function.
169 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
171 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
172 of blocks which need to be moved, and moves those blocks
173 to another location in the filesystem.
175 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
176 bitmap, make sure all of the new parts of the bitmap are
179 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
181 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
182 wasn't being returned to the caller.
184 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
185 ext2fs_allocate_group_table() which sets the group tables
186 for a particular block group. The relevant code was
187 factored out of ext2fs_allocate_tables().
189 * dblist.c (make_dblist): Adjust the initial size of the directory
190 block list to be a bit more realistic (ten plus twice the
191 number of directories in the filesystem).
193 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
195 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
196 ext2fs_badblocks_list_test would test the list (and exceed
197 array boundaries) if there were no bad blocks on the bad
198 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
200 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
202 * Release of E2fsprogs version 1.10
204 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
206 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
207 inode and block bitmaps based on the RAID 0 stride
208 parameter (which is passed by mke2fs).
210 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
211 mke2fs to communicate the stride length to
212 ext2fs_allocate_tables()
214 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
216 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2

232 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
234 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
235 free if refcount goes to zero.

251 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
253 (unix_close, test_close): Decrement the refcount and only
254 close the io_channel if the refcount goes to 0.
256 * io.h: Add refcount to the io_channel structure. Add new macro
257 interface io_channel_bumpcount() to bump the refcount.
259 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
261 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
262 cache in the filesystem handle, instead of the inode cache
263 in a static variable.
265 * freefs.c: Added static function to free the inode cache (called by
268 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
270 * ext2fs.h: Added pointer to the inode_cache structure.
272 * block.c (block_iterate_ind, block_iterate_dind,
273 block_iterate_tind): If there are holes in the indirect,
274 doubly indirect, or triply indirect blocks, increment the
275 block count field automatically.
277 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
279 * Release of E2fsprogs version 1.09
281 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
283 * version.c (ext2fs_parse_version_string): Check the passed in
284 version string (instead of the hard-coded one).
286 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
287 greater filesystem size, clamp it to prevent allocating a
288 block or inode bitmap beyond the filesystem.
290 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
291 overhead calculation was accidentally removed.
293 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
295 * Release of E2fsprogs version 1.08
297 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
299 * dblist.c (ext2fs_set_dir_block): New function which sets the
300 block of a dblist entry, given the directory inode and
303 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
305 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
306 inode bitmaps at staggered locations across the block
307 groups, to avoid concentrating the bitmaps on a small
308 number of disks when using striped RAID arrays.
310 * initialize.c (ext2fs_initialize): By default, choose the maximum
311 possible number of blocks per group (based on the size of
312 the bitmaps in the blocksize).
314 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
316 * initialize.c (ext2fs_initialize): Add support for
317 EXT2_COMPAT_SPARSE_SUPER feature.
319 * closefs.c (ext2fs_bg_has_super): New function to determine
320 whether or a particular block group should have a
321 superblock and block group descriptor. Used for the
322 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
323 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
324 or not the superblock should be written out for the block
327 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
328 for sparse duplicate superblocks.
330 * version.c (ext2fs_get_library_version): New function which
331 returns the library version.
333 * version.c (ext2fs_parse_version_string): New function which
334 parses a version string and returns a version number,
335 so application programs can compare version numbers as
338 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
340 * icount.c (ext2fs_create_icount): Change function so that it also
341 takes a new argument which contains a "hint" icount
342 structure. This "hint" icount allows the create function
343 to set up the sorted list in advance. This reduces
344 significantly the amount of data moving needed to insert
345 these inodes into the list later.
347 * icount.c (ext2fs_icount_validate): New function which validates
348 that the icount structure's rep invariant.
350 * icount.c (get_icount_el): Completely revamped implementation
351 to subsume put_icount_el(). Put_icount_el() used to
352 use an O(N) implementation to insert in the middle
353 of the icount list. It now uses a O(ln N) to search
354 for where the icount should be inserted, and then uses
355 a memcpy to move the list down (instead of a for loop).
357 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
358 ext2fs_icount_increment, ext2fs_icount_decrement): Check
359 to see if the inode is within bounds; if it isn't, return
362 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
363 when a bad inode number is passed to test_generic_bitmap
364 to be EXT2FS_TEST_ERROR instead of the wrong
367 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
369 * Release of E2fsprogs version 1.07
371 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
373 * Makefile.in (ELF_VERSION): Change version to be 2.2
375 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
377 * alloc.c (ext2fs_get_free_blocks): Change routine to use
378 ext2fs_fast_test_block_bitmap_range().
380 * bitops.h (ext2fs_fast_test_block_bitmap_range,
381 ext2fs_test_block_bitmap_range: New inline functions which
382 test to see whether a contiguous range of blocks is
385 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
387 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
388 use ext2fs_badblocks_* instead of badblocks_*
390 * bb_compat.c: New file which translates between old badblocks_*()
391 names to ext2fs_badblocks_*()
393 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
394 link.c (since e2fsck doesn't use ext2fs_unlink()).
396 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
397 bitmap resizing routine moved from bitmaps.c, since e2fsck
398 doesn't need to use this function.
400 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
401 since e2fsck only needs ext2fs_lookup.
403 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
405 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
406 already set; this is needed so that programs like dump
407 which use the inode scan functions will deal with
408 filesystems that have bad blocks in the inode table.
410 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
412 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
413 Moved to ext2fsP.h, since it doesn't need to be part of
414 the public interface.
416 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
418 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
420 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
421 directory block list abstraction. (Code moved from
424 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
425 to inode.c (since no one else should be peeking inside it!)
427 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
429 * openfs.c (ext2fs_open): Check the feature set in the ext2
430 superblock, and refuse to open filesystems if they contain
431 incompatible features. (Can be overriden with the
434 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
436 * block.c (ext2fs_block_iterate2): Added new function
437 ext2fs_block_iterate2 which changes the function
438 signature of the callback function to include the
439 referencing block and offset.
441 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
442 ext2fs_inode_scan_goto_blockgroup which allows an
443 application to jump to a particular block group while
446 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
448 * dirblock.c: Include string.h, since we use memcpy().
450 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
452 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
453 a long not an int; this doesn't matter on i386 machines,
454 but it does on Alpha's.
456 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
458 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
459 table pointer is NULL, then return an error indicating
460 that the inode table is missing.
461 (get_next_blockgroup, get_next_blocks,
462 ext2fs_get_next_inode): Don't treat a missing inode table
463 as permanent error. Return MISSING_INODE_TABLE, but as an
464 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
466 * rw_bitmaps.c (ext2fs_write_block_bitmap,
467 ext2fs_write_inode_bitmap): If the inode or block bitmap
468 block is zero, then don't write out the inode or block
469 bitmap. The idea here is to avoid stomping on the
471 (read_bitmaps): If the inode or block bitmap block is
472 zero, then fill in that portion of the inode or block
473 bitmap with all zeros.
475 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
476 blocks in inode table when the inode table size is
477 non-standard (and can therefore span blocks).
479 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
481 * alloc.c (ext2fs_new_block): Fix fencepost error in
482 ext2fs_new_block; make sure we don't try to allocate the
483 first block beyond the end of the filesystem.
485 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
487 * inode.c (check_for_inode_bad_blocks): New function called by
488 get_next_blocks() to avoid reading in bad blocks marked in
489 fs->badblocks. Inodes located in bad blocks are returned
490 by ext2fs_get_next_inode() returns the error code
491 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
493 * alloc_tables.c (ext2fs_allocate_tables): New function which
494 performs the part of mke2fs's job of allocating the
497 * test_io.c (test_close): IO manager which is used for testing
500 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
502 * inode.c (ext2fs_get_next_inode): Separate out the function of
503 setting up for a new block group to get_next_blockgroup().
504 Separate out the function of reading in blocks of the
505 inode table to get_next_blocks().
507 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
509 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
510 blocks to the badblock list in sorted order. This allows
511 badblocks_list_test to be coded using a binary search for
514 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
516 * Release of E2fsprogs version 1.06
518 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
520 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
521 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
524 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
525 set, then only write out the master superblock.
527 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
529 * block.c (ext2fs_block_iterate): Fixed bug which caused
530 block_iterate to fail to handle HURD created filesystems;
531 it tested the inode translator field before the inode was
534 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

565 * namei.c (ext2fs_follow_link): New function.
566 (ext2fs_namei): Extended to have support for chasing
567 symbolic links. ext2fs_namei() still returns an inode
568 which is a symbolic link. Symbolic links are only chased
569 while resolving the containing directory. To chase
570 symbolic links of the final result, use
571 ext2fs_follow_link().

583 order is not i386 compatible, set the swap_byte flag.
585 * inode.c (inocpy_with_swap): Check to see if inode contains a
586 fast symlink before swapping the inode block fields. This
587 required adding a new argument to inocpy_with_swap to
588 determine whether the mode field is in host order or not.

599 * block.c (ext2fs_block_iterate): Cause block iterator to return
600 the HURD translator block (along with everything else).
601 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
602 iterator, then don't return any meta data blocks
603 (including the HURD translator).
605 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

619 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
621 * openfs.c (ext2fs_open): If the blocksize in the superblock is
622 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
623 that's a basic value that must be correct for the rest of
626 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error

739 Move these functions to freefs.c.
741 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
742 descriptors shadow memory to keep purify quiet. (This
743 also has the nice benefit that the unused portion of the
744 shadow descriptors are zeroed out.)
746 * dirblock.c (ext2fs_write_dir_block): We need to use
747 dirent->rec_len *before* it's byteswapped to find the
748 location of the next directory structure!
750 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
751 cause ext2fs_new_inode to loop infinitely if we're trying
752 to allocate an inode in group #0 and there are no free
753 inodes at all in the system.

796 to desp ext2 filesystem structures.
798 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
799 supplied by Pete A. Zaitcev so that the C language
800 versions of these functions are more portable. They will
801 now work on both little and big endian systems, and the
802 assumption that 32-bit integers are used is gone.
804 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
807 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

877 allows us to compile e2fsprogs on a non-Linux system,
878 which may have a different value for S_IFDIR.

918 compat code to protect against overflow. This only
919 applies to 1.0 and early 1.1 kernels, which don't support
920 the llseek() system call.
922 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)

925 io_channel pointers to be null.
927 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
928 found, clear it but don't try to update the filesystem
929 accounting information, since that's hopeless anyway.
931 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
932 bloblock_iterate_tind): Check to see if the indirect blocks are
933 valid before trying to read them.

941 illegal block or inode number is passed in, return instead
942 of trying to test, set, or clear the bit.

1032 * initialize.c: Completely revamped the inode and block bitmap
1033 structures, so that they can be better chance of being extensible
1034 in a shared library. They are now their own type, instead of
1035 being a char *. Also, the function signatures of
1036 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1037 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
