19 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
20 provides the function ext2fs_find_block_device(). This
21 function returns the pathname to a block device, given its
24 2000-07-13 <tytso@valinux.com>
26 * Release of E2fsprogs 1.19

56 returns true if two badblocks list are equal.
58 * Makefile.in: Remove explicit link of -lc in the shared library.

65 2000-05-27 Theodore Ts'o <tytso@valinux.com>
67 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode

71 2000-05-25 <tytso@snap.thunk.org>
73 * getsize.c (ext2fs_get_device_size): Use open64() instead of
74 open() if it exists. Under linux, manually define the
75 ioctl for BLKGETSIZE if it isn't already defined and it's
78 * unix_io.c (unix_open): Use open64() instead of open() if it
81 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
82 available (and prototypes are defined) use it in
85 * Makefile: Add hack dependency rule so that parallel makes work

98 how to define __s64 and __u64. Turn off "compression is
99 experimental" warning if the cpp macro
100 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
102 2000-02-11 <tytso@snap.thunk.org>
104 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
105 Conditionally include Compression as a supported type if
106 ENABLE_COMPRESSION (via --enable-compression) is turned on.
108 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
110 2000-02-08 <tytso@snap.thunk.org>

116 being marked or unmarked. For speed optimization.
118 2000-02-02 Theodore Ts'o <tytso@valinux.com>
120 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
122 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
123 needed any more; we know it will always be i_generation.
124 Add support for swapping the high bits of the uid and gid.
126 1999-11-19 <tytso@valinux.com>
128 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link

139 1999-11-08 <tytso@valinux.com>
141 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
142 since ext2fs_badblocks_list_free was moved to freefs.c.
144 * tst_badblocks.c: Use the newer badblocks API names. Add
145 duplicate blocks to the test inputs to test dealing with
146 adding blocks which are already in the badblocks list.
148 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
149 of the list, use a shortcut O(1) operations instead of an
150 O(n) operation. (Idea suggested by David Beattie.)
152 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
153 of badblocks_list_free(), to save a procedure call.
155 1999-10-26 <tytso@valinux.com>
157 * Release of E2fsprogs 1.17
159 1999-10-26 <tytso@valinux.com>

162 seem to handle ~0UL the same way as they used to.
164 1999-10-25 <tytso@valinux.com>
166 * nt_io.c (_OpenNtName): Open the device using
167 FILE_SYNCHRONOUS_IO_NONALERT instead of
168 FILE_SYNCHRONOUS_IO_ALERT
169 (nt_open): At the end of the device open routine, unlock
170 the drive but do not dismount it.
172 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
175 1999-10-22 <tytso@valinux.com>
177 * Release of E2fsprogs 1.16
179 1999-10-22 <tytso@valinux.com>
181 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
183 * link.c (ext2fs_link): This call now uses the low three bits of
184 the flags parameter to pass the directory filetype
185 information; it will set the directory entry FILETYPE
186 information if the filesystem supports it.
188 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
189 option is set, then create the '.' and '..' entries with
190 the filetype set to EXT2_FT_DIR.
192 1999-09-24 <tytso@valinux.com>
194 * nt_io.c: New file which supports I/O under Windows NT.
196 1999-09-07 <tytso@valinux.com>
198 * ext2fs.h: Add new fields for journalling and define new
199 feature bits used by newer filesystems: IMAGIC_INODES,
200 HAS_JOURNAL, RECOVER.
202 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
203 we update the inode block count and size files so that the
204 block count field is updated correctly when we create an
207 1999-07-18 Theodore Ts'o <tytso@valinux.com>
209 * Release of E2fsprogs 1.15
211 1999-06-23 <tytso@valinux.com>
213 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
214 kernels that use i_generation instead of i_version. Patch
215 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
217 1999-06-21 <tytso@valinux.com>
219 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
220 directory entry before calling the callback function.
221 This should prevent some core dumps of insufficiently
222 paranoid callback functions.
224 1999-05-29 <tytso@rsts-11.mit.edu>
226 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
228 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
229 that we don't handle writing yet (we do). Fixed bug where
230 we weren't allocating a big enough buffer for ext2_bmap.
232 1999-05-03 <tytso@rsts-11.mit.edu>
234 * openfs.c (ext2fs_open): Check to make sure that the number of
235 blocks per group is not zero --- if so, it must be a bad
238 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
240 * Release of E2fsprogs 1.14
242 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
244 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
245 the inode number is zero; if it's zero, return
246 EXT2_ET_BAD_INODE_NUM.
248 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
250 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
251 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
254 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
256 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
257 non-Linux case to use EINVAL by default, unless it isn't
258 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
261 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
263 * Release of E2fsprogs 1.13
265 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
267 * Makefile.in: Updated dependencies.
269 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
271 * initialize.c (ext2fs_initialize): Make sure that we allocate
272 enough inodes so that we can make a valid filesystem.
274 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
276 * rw_bitmaps.c: Fixed signed/unsigned warnings.
278 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
279 function declaration.
281 * dblist.c (make_dblist): Add safety check in case the dblist
282 pointer passed in is null (in which case, assign it to
283 fs->dblist). Fixed some signed/unsigned warnings.
285 * bmap.c: Make addr_per_block be of type blk_t to avoid
286 signed/unsigned warnings.
288 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
289 function declaration.
291 * get_pathname.c (get_pathname_proc): Use return value from

296 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
297 from the function declaration.
299 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
300 return the error directly instead of jumping to the
301 cleanup routine, since we don't need to do any cleanup.
303 * alloc_table.c (ext2fs_allocate_group_table): Make this
304 function take a dgrp_t for its group argument.
306 * ext2fs.h: Make dgrp_t an __u32 type, and make
307 fs->desc_group_count be of type dgrp_t.
309 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
311 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
312 than 10 blocks when we need to expand the size of the
315 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
317 * Release of E2fsprogs 1.12
319 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
321 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
322 appropriate for all of the block group copies, so that
323 it's clear where the beginning of the filesystem is on the
324 disk. (For when the partition table gets scrod.)
326 * ext2fs.h: Change the name of the feature from
327 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
328 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
330 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
332 * inode.c (get_next_blockgroup): Fix bug where if
333 get_next_blockgroup() is called early because of a missing
334 inode table in a block group, the current_inode counter
335 wasn't incremented correctly.
337 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
339 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
340 against a completely trashed bad block inode.
342 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
344 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
345 the stride length hits a bad value, we retry the block
346 allocation starting at the beginning of the block group.
348 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
349 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
350 e2_blkcnt_t to avoid collision with LFS API.
352 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
354 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
355 way that avoids overflows on disk sizes greater than 4GB.
357 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
359 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
360 return type for comparison functions for qsort.
362 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
365 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
367 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
370 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
371 evade a potential problem with glibc's header files trying
372 to spike out linux/types.h.
374 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
375 include the old size of the memory, which is needed for
376 some braindamaged memory allocation systems that don't
379 * badblocks.c (ext2fs_badblocks_list_add):
380 bb_inode.c (clear_bad_block_proc):
381 dblist.c (ext2fs_add_dir_block):

385 pass the old size of the memory to be resized to
388 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
390 * Makefile.in: Change to use new installation directory variables
391 convention. Fix uninstall rules to take $(DESTDIR) into
394 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
396 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
397 with 32 bit longs, then we need to manually define __s64
398 and __u64, since the current kernel header files don't
399 define these if __STRICT_ANSI__ is defined. This is a
400 problem if we are compiling with full GCC warnings, since
401 we do need 64 bit support.
403 * Makefile.in (OBJS): Remove bmove.o from files to be built,
404 since we're not using ext2fs_move_blocks() and there
405 is some question as to its usefulness in its current
408 * bmap.c (block_bmap): Remove unused function.
410 * bmove.c (process_block): Fix -Wall warning.
412 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
414 * block.c (ext2fs_block_iterate3): Make the ref_offset field
415 contain the offset into the inode.i_blocks array when
416 ref_block is zero. Since we haven't done a formal
417 release of e2fsprogs since block_iterate2 was first
418 introduced, I removed block_iterate2, and renamed
419 block_iterate3 to be block_iterate2.
421 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
422 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
423 use of block_iterate and block_iterate2 to
424 block_iterate2 with the new prototype for the
425 interator function. (using blkcnt_t forr blockcount)
427 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
429 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
430 s_prealloc_blocks, s_prealloc_dir_blocks). Added
431 conditional defines of new features COMPAT_DIR_PREALLOC,
432 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
433 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
434 the library to declare that we support COMPAT_DIR_PREALLOC,
435 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
437 * fileio.c: Rename function ext2fs_file_llseek to be
438 ext2fs_file_lseek, which is more accurate.
440 * block.c: Add new function ext2fs_block_iterate3 which calls
441 the iterator function with the blockcount argument of
442 type blkcnt_t. This version of the function is
443 allowed to handle large files; the other fucntions are
446 * ext2fs.h: Add new type blkcnt_t
448 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
450 * block.c (ext2fs_block_iterate2): Fix bug where the block count
451 field wasn't getting correctly incremented for sparse
452 files when the indirect or doubly-indirect block
453 specified in the inode was zero.
455 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
457 * unlink.c (unlink_proc):
458 * lookup.c (lookup_proc):
459 * link.c (link_proc):
460 * get_pathname.c (get_pathname_proc):
461 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
462 from dirent->name_len, so it can be used for other
465 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
466 and indicate that we have support for this incompatible
469 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
471 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

475 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
476 number of directories when the block group information is
479 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
481 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
482 inode table is missing so that we catch the case where the
483 first block group is missing.
485 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
488 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
490 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
492 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
494 * test_io.c (test_flush): Add a debugging printf when the flush
497 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
498 read in, return right away.
500 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
502 * bitops.h: Don't try to do i386 inline asm functions if the
505 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
506 instead of linux/types.h, and e2_bitops.h instead of
509 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
512 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
514 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
515 so that we don't need to call get_next_blockgroup() the
516 first time around. Saves a bit of time, and prevents us
517 from needing to assign -1 to current_group (which is an
520 * icount.c (insert_icount_el): Cast the estimated number of inodes
521 from a float to an ino_t.

536 ext2-specific header files are in a flat directory.
538 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
539 all assignments from void * to be compatible with C++.

557 unlink.c: Change private to be priv_data (to avoid C++
560 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
562 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
563 paranoid about validating the directory counts from the
564 block group information.
566 * all files: Don't include stdlib.h anymore; include it in
567 ext2_fs.h, since that file requires stdlib.h
569 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
571 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
572 bitmap is loaded, and return an error if it is not.
573 (expand_dir_proc): Only use ext2fs_write_dir_block when

599 * Rename new error codes to _ET_ in them for consistency.
601 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
603 * [all files, basically]: Added definition of ext2fs_get_mem,
604 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
605 changed all library routines to use these wrapper functions.
607 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
608 instead of the system error messages.

625 * fileio.c: New file which implements simple file reading and
628 * alloc.c (ext2fs_alloc_block): New function which allocates a
629 block, zeros it, and updates the filesystem accounting
630 records appropriately.
632 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
634 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
635 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
636 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY

643 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
644 need to declare llseek().
646 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
648 * Rename io.h to be ext2_io.h (avoid namespace collisions)
650 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H

688 * io.h: Change the prototype of ext2fs_llseek() to use int's
689 instead of unsigned int's.
691 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
692 to make life easer for GNU Libc 2.
694 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
695 filesystem has its bitmaps stored as 32-bit words with bit
696 0 as the LSB of each word. Thus a bitmap with only bit 0
697 set would be, as a string of bytes, 00 00 00 01 00 ... To
698 cope with this, we byte-reverse each word of a bitmap if
699 we have a big-endian filesystem, that is, if we are *not*
700 byte-swapping other word-sized numbers.

766 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
767 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
769 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
771 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
772 is zero, then return EXT2_IO_LLSEEK_FAILED.
774 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
776 * Release of E2fsprogs 1.11
778 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
780 * dblist.c (ext2fs_dblist_count): Added new function which returns
781 the number of directory blocks in dblist.
783 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
785 * unix_io.c (unix_flush): Make the io_channel flush function do a
786 fsync to flush the kernel buffers to disk.
788 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
790 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
791 current inode number wasn't being set by the
792 goto_blockgroup function.
794 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
796 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
797 of blocks which need to be moved, and moves those blocks
798 to another location in the filesystem.
800 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
801 bitmap, make sure all of the new parts of the bitmap are
804 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
806 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
807 wasn't being returned to the caller.
809 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
810 ext2fs_allocate_group_table() which sets the group tables
811 for a particular block group. The relevant code was
812 factored out of ext2fs_allocate_tables().
814 * dblist.c (make_dblist): Adjust the initial size of the directory
815 block list to be a bit more realistic (ten plus twice the
816 number of directories in the filesystem).
818 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
820 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
821 ext2fs_badblocks_list_test would test the list (and exceed
822 array boundaries) if there were no bad blocks on the bad
823 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
825 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
827 * Release of E2fsprogs version 1.10
829 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
831 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
832 inode and block bitmaps based on the RAID 0 stride
833 parameter (which is passed by mke2fs).
835 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
836 mke2fs to communicate the stride length to
837 ext2fs_allocate_tables()
839 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
841 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2

857 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
859 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
860 free if refcount goes to zero.
862 * inode.c (create_icache): Initialize refcount to 1.
864 * ext2fsP.h: Added refcount to ext2_inode_cache
866 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
869 * badblocks.c (ext2fs_badblocks_copy): New function to copy a

876 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
878 (unix_close, test_close): Decrement the refcount and only
879 close the io_channel if the refcount goes to 0.
881 * io.h: Add refcount to the io_channel structure. Add new macro
882 interface io_channel_bumpcount() to bump the refcount.
884 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
886 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
887 cache in the filesystem handle, instead of the inode cache
888 in a static variable.
890 * freefs.c: Added static function to free the inode cache (called by
893 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
895 * ext2fs.h: Added pointer to the inode_cache structure.
897 * block.c (block_iterate_ind, block_iterate_dind,
898 block_iterate_tind): If there are holes in the indirect,
899 doubly indirect, or triply indirect blocks, increment the
900 block count field automatically.
902 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
904 * Release of E2fsprogs version 1.09
906 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
908 * version.c (ext2fs_parse_version_string): Check the passed in
909 version string (instead of the hard-coded one).
911 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
912 greater filesystem size, clamp it to prevent allocating a
913 block or inode bitmap beyond the filesystem.
915 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
916 overhead calculation was accidentally removed.
918 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
920 * Release of E2fsprogs version 1.08
922 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

925 block of a dblist entry, given the directory inode and
928 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
930 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
931 inode bitmaps at staggered locations across the block
932 groups, to avoid concentrating the bitmaps on a small
933 number of disks when using striped RAID arrays.
935 * initialize.c (ext2fs_initialize): By default, choose the maximum
936 possible number of blocks per group (based on the size of
937 the bitmaps in the blocksize).
939 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
941 * initialize.c (ext2fs_initialize): Add support for
942 EXT2_COMPAT_SPARSE_SUPER feature.
944 * closefs.c (ext2fs_bg_has_super): New function to determine
945 whether or a particular block group should have a
946 superblock and block group descriptor. Used for the
947 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
948 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
949 or not the superblock should be written out for the block
952 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
953 for sparse duplicate superblocks.
955 * version.c (ext2fs_get_library_version): New function which
956 returns the library version.
958 * version.c (ext2fs_parse_version_string): New function which

960 so application programs can compare version numbers as
963 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
965 * icount.c (ext2fs_create_icount): Change function so that it also
966 takes a new argument which contains a "hint" icount
967 structure. This "hint" icount allows the create function
968 to set up the sorted list in advance. This reduces
969 significantly the amount of data moving needed to insert
970 these inodes into the list later.
972 * icount.c (ext2fs_icount_validate): New function which validates
973 that the icount structure's rep invariant.
975 * icount.c (get_icount_el): Completely revamped implementation
976 to subsume put_icount_el(). Put_icount_el() used to
977 use an O(N) implementation to insert in the middle
978 of the icount list. It now uses a O(ln N) to search
979 for where the icount should be inserted, and then uses
980 a memcpy to move the list down (instead of a for loop).
982 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
983 ext2fs_icount_increment, ext2fs_icount_decrement): Check
984 to see if the inode is within bounds; if it isn't, return
987 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
988 when a bad inode number is passed to test_generic_bitmap
989 to be EXT2FS_TEST_ERROR instead of the wrong
992 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
994 * Release of E2fsprogs version 1.07
996 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
998 * Makefile.in (ELF_VERSION): Change version to be 2.2
1000 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1002 * alloc.c (ext2fs_get_free_blocks): Change routine to use
1003 ext2fs_fast_test_block_bitmap_range().
1005 * bitops.h (ext2fs_fast_test_block_bitmap_range,
1006 ext2fs_test_block_bitmap_range: New inline functions which
1007 test to see whether a contiguous range of blocks is
1010 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1012 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
1013 use ext2fs_badblocks_* instead of badblocks_*
1015 * bb_compat.c: New file which translates between old badblocks_*()
1016 names to ext2fs_badblocks_*()
1018 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
1019 link.c (since e2fsck doesn't use ext2fs_unlink()).
1021 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
1022 bitmap resizing routine moved from bitmaps.c, since e2fsck
1023 doesn't need to use this function.
1025 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
1026 since e2fsck only needs ext2fs_lookup.
1028 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1030 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
1031 already set; this is needed so that programs like dump
1032 which use the inode scan functions will deal with
1033 filesystems that have bad blocks in the inode table.
1035 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1037 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1038 Moved to ext2fsP.h, since it doesn't need to be part of
1039 the public interface.
1041 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1043 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1045 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1046 directory block list abstraction. (Code moved from
1049 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1050 to inode.c (since no one else should be peeking inside it!)
1052 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1054 * openfs.c (ext2fs_open): Check the feature set in the ext2
1055 superblock, and refuse to open filesystems if they contain
1056 incompatible features. (Can be overriden with the
1059 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1061 * block.c (ext2fs_block_iterate2): Added new function
1062 ext2fs_block_iterate2 which changes the function
1063 signature of the callback function to include the
1064 referencing block and offset.
1066 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1067 ext2fs_inode_scan_goto_blockgroup which allows an
1068 application to jump to a particular block group while
1069 doing an inode scan.
1071 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1073 * dirblock.c: Include string.h, since we use memcpy().
1075 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1077 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1078 a long not an int; this doesn't matter on i386 machines,
1079 but it does on Alpha's.
1081 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1083 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1084 table pointer is NULL, then return an error indicating
1085 that the inode table is missing.
1086 (get_next_blockgroup, get_next_blocks,
1087 ext2fs_get_next_inode): Don't treat a missing inode table
1088 as permanent error. Return MISSING_INODE_TABLE, but as an
1089 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1091 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1092 ext2fs_write_inode_bitmap): If the inode or block bitmap
1093 block is zero, then don't write out the inode or block
1094 bitmap. The idea here is to avoid stomping on the
1096 (read_bitmaps): If the inode or block bitmap block is
1097 zero, then fill in that portion of the inode or block
1098 bitmap with all zeros.
1100 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1101 blocks in inode table when the inode table size is
1102 non-standard (and can therefore span blocks).
1104 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1106 * alloc.c (ext2fs_new_block): Fix fencepost error in
1107 ext2fs_new_block; make sure we don't try to allocate the
1108 first block beyond the end of the filesystem.
1110 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1112 * inode.c (check_for_inode_bad_blocks): New function called by
1113 get_next_blocks() to avoid reading in bad blocks marked in
1114 fs->badblocks. Inodes located in bad blocks are returned
1115 by ext2fs_get_next_inode() returns the error code
1116 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1118 * alloc_tables.c (ext2fs_allocate_tables): New function which
1119 performs the part of mke2fs's job of allocating the
1122 * test_io.c (test_close): IO manager which is used for testing
1125 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1127 * inode.c (ext2fs_get_next_inode): Separate out the function of
1128 setting up for a new block group to get_next_blockgroup().
1129 Separate out the function of reading in blocks of the
1130 inode table to get_next_blocks().
1132 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1134 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1135 blocks to the badblock list in sorted order. This allows
1136 badblocks_list_test to be coded using a binary search for
1139 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1141 * Release of E2fsprogs version 1.06
1143 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1145 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1146 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1149 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1150 set, then only write out the master superblock.
1152 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1154 * block.c (ext2fs_block_iterate): Fixed bug which caused
1155 block_iterate to fail to handle HURD created filesystems;
1156 it tested the inode translator field before the inode was
1159 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1161 * initialize.c (ext2fs_initialize): Make sure the description for
1162 the inode bitmap is set correctly.
1164 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

1168 * Release of E2fsprogs version 1.05
1170 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1172 * initialize.c: Override the kernel's idea of default
1173 checkinterval from 0 (never) to 180 days.

1177 * namei.c (ext2fs_namei_follow): New function which follows
1178 symbolic link (if any) at the target.
1180 Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1182 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
1183 for shortcut function fs->read_inode() and fs->write_inode().
1184 Added inode_cache to reduce CPU time spent in doing

1190 * namei.c (ext2fs_follow_link): New function.
1191 (ext2fs_namei): Extended to have support for chasing
1192 symbolic links. ext2fs_namei() still returns an inode
1193 which is a symbolic link. Symbolic links are only chased
1194 while resolving the containing directory. To chase
1195 symbolic links of the final result, use
1196 ext2fs_follow_link().
1198 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1200 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1202 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines

1207 * initialize.c (ext2fs_initialize): On systems where the byte
1208 order is not i386 compatible, set the swap_byte flag.
1210 * inode.c (inocpy_with_swap): Check to see if inode contains a
1211 fast symlink before swapping the inode block fields. This
1212 required adding a new argument to inocpy_with_swap to
1213 determine whether the mode field is in host order or not.
1215 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1217 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1218 the sparc, if EXT2_STD_BITOPS set, use the standard
1219 i386-compatible bitmask operations, instead on the
1220 non-standard native bitmask operators.
1222 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1224 * block.c (ext2fs_block_iterate): Cause block iterator to return
1225 the HURD translator block (along with everything else).
1226 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1227 iterator, then don't return any meta data blocks
1228 (including the HURD translator).
1230 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1232 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1234 * uuid.c: New file, containing UUID utility functions.
1236 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1238 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1240 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1242 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1244 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1246 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1247 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1248 that's a basic value that must be correct for the rest of
1249 the library to work.
1251 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1254 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1264 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit):
1265 Change the m68k bit numbering for bitmasks to match with
1266 the bit numbering used by all other ext2 implementations.
1268 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1270 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,
1271 ext2fs_open_inode_scan): Support dynamically-sized inodes.
1273 Wed Mar 6 12:26:29 1996 <tytso@rsts-11.mit.edu>

1284 the passed in size is *really* too small.
1286 * alloc.c (ext2fs_new_inode):
1287 * ext2fs.h (EXT2_FIRST_INODE): Add support for dynamic revision to
1290 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>

1293 when trying to determine its size.
1295 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1297 * Release of E2fsprogs version 1.02
1299 Sat Dec 9 09:57:50 1995 <tytso@rsts-11.mit.edu>

1302 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1303 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1304 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1305 to avoid conflicts with with kernel include files. Also
1306 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1309 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1311 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1313 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1314 s_def_resuid and s_def_resgid for backwards compatibility.
1316 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
1318 * bitops.h: Added #ifdef's for Sparc.
1320 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
1322 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
1325 * closefs.c: #include <string.h> to pick up memset() declaration
1327 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1329 * Makefile.in: Added support for BSD shared libraries.
1331 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1334 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1336 * unix_io.c (unix_open): Add a double check; if the passed in name
1337 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1339 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1341 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
1343 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of

1348 * getsize.c (ext2fs_get_device_size): Add support for reading the
1349 partition size from a BSD disk label.
1351 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1353 * getsize.c (ext2fs_get_device_size): New function that determins
1354 the size of a device. Used by mke2fs and e2fsck.
1356 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1358 * Makefile.in (install): Install static libraries in $(ulibdir)
1359 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).

1363 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1364 Move these functions to freefs.c.
1366 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1367 descriptors shadow memory to keep purify quiet. (This
1368 also has the nice benefit that the unused portion of the
1369 shadow descriptors are zeroed out.)
1371 * dirblock.c (ext2fs_write_dir_block): We need to use
1372 dirent->rec_len *before* it's byteswapped to find the
1373 location of the next directory structure!
1375 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1376 cause ext2fs_new_inode to loop infinitely if we're trying
1377 to allocate an inode in group #0 and there are no free
1378 inodes at all in the system.
1380 * closefs.c: #include <errno.h> if it exists.
1382 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1384 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1390 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1391 installation directories correctly.
1393 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1395 * namei.c (process_dir_block):
1396 * mkdir.c (ext2fs_mkdir):
1397 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1398 to read/write the directory block.
1400 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1401 file containing functions for reading and writing
1402 directory blocks (byte swapping if necesssary)
1404 * block.c (block_iterate_ind, block_iterate_dind,
1405 block_iterate_tind): Byte swap the block addresses if
1406 EXT2_SWAP_BYTES is set (and swap them back before writing
1409 * inode.c (inocpy_with_swap): New function.
1410 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1411 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1413 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1414 the superblock and group descriptors before writing it out.
1416 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1417 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1418 and group descriptors.
1420 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1421 to desp ext2 filesystem structures.
1423 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1424 supplied by Pete A. Zaitcev so that the C language
1425 versions of these functions are more portable. They will
1426 now work on both little and big endian systems, and the
1427 assumption that 32-bit integers are used is gone.
1429 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1430 doing byte swapping.
1432 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1433 byte swapping should take place.
1435 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

1446 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1447 if the magic number is correct, it will be allocated.
1449 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1451 * block.c (block_iterate_ind, block_iterate_dind,
1452 block_iterate_tind): Don't recompute block_nr each loop;
1453 just increment it! Factor check of BLOCK_FLAG_APPEND out
1454 of the loop. Factor mask of BLOCK_CHANGED into changed
1455 variable out of the loop. (block_iterate_ind, in
1456 particular, gets called a lot, so every little
1457 optimization helps.)
1459 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1461 * block.c (block_iterate_ind, block_iterate_dind,
1462 block_iterate_tind): Precompute limit of loop to speed up
1463 block_iterate_ind and company.

1467 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1468 ext2fs_fast_test_inode_bitmap): Add fast version of these
1469 functions, which don't do range checking.
1471 * bitops.h (ext2fs_get_block_bitmap_start,
1472 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1473 ext2fs_get_inode_bitmap_end): Add new accessor functions
1474 which return the start and end points of the bitmaps.
1476 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1478 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1479 instead of llseek. The errno if the offset is too large
1480 and lseek is not supported should be EINVAL, not -EINVAL.
1482 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1484 * Makefile.in: Added support for ELF shared libraries.
1485 Fixed typos in the compilation rules.
1486 (distclean): Added Makefile.
1488 * llseek.c (llseek): New function, if llseek() does not exist in the
1490 (ext2_llseek): Changed to call llseek().
1492 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1494 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.

1498 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1500 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1501 the S_*, which are normally defined in <sys/stat.h>. This
1502 allows us to compile e2fsprogs on a non-Linux system,
1503 which may have a different value for S_IFDIR.
1505 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1507 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1508 this is a user-mode application!
1510 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1512 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1513 __linux__ so that non-linux systems won't see it.
1515 * alloc.c: Include <errno.h> if possible.
1516 * badblocks.c: Ditto.
1517 * bb_inode.c: Ditto.
1520 * expanddir.c: Ditto.
1521 * get_pathname.c: Ditto.
1522 * initialize.c: Ditto.
1529 * rw_bitmaps.c: Ditto.
1532 * Makefile.in: Rewritten to conform to GNU coding standards and
1533 support separate compilation directories.
1535 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1537 * initialize.c (ext2fs_initialize): Don't allow more than one
1538 bitmaps's worth of inodes in a group.
1540 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1542 * llseek.c (ext2_llseek): Added error checking to the llseek()
1543 compat code to protect against overflow. This only
1544 applies to 1.0 and early 1.1 kernels, which don't support
1545 the llseek() system call.
1547 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1549 * unix_io.c (unix_open): Initialize the read_error and write_error
1550 io_channel pointers to be null.
1552 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1553 found, clear it but don't try to update the filesystem
1554 accounting information, since that's hopeless anyway.
1556 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1557 bloblock_iterate_tind): Check to see if the indirect blocks are
1558 valid before trying to read them.
1560 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1561 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1563 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1564 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1565 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1566 illegal block or inode number is passed in, return instead
1567 of trying to test, set, or clear the bit.
1569 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1571 * Makefile: Added a dummy install target in case shared libraries
1574 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1576 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1577 the real last block of the bitmap should be calculated.
1579 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
1581 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1582 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1583 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1584 ext2fs_free_block_bitmap): Add magic number checking for
1585 the inode and block bitmaps.
1587 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1588 magic number for a block bitmap instead of an inode bitmap.
1590 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1591 magic number checking for the inode_scan structure.
1593 * badblocks.c (badblocks_list_free, badblocks_list_add,
1594 badblocks_list_test, badblocks_list_iterate_begin,
1595 badblocks_list_iterate, badblocks_list_iterate_end): Add
1596 magic number checking for the badblocks_list and
1597 badblocks_iterate structures.
1599 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1600 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1601 unix_write_blk, unix_flush): Add magic number checking
1602 both for io_channel structure and unix_private_data
1605 * openfs.c (ext2fs_open): Add check for io_manager structure's
1608 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1609 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1610 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1611 * read_bb.c (ext2fs_read_bb_inode):
1612 * read_bb_file.c (ext2fs_read_bb_FILE):
1613 * newdir.c (ext2fs_new_dir_block):
1614 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
1615 * link.c (ext2fs_link, ext2fs_unlink):
1616 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
1617 ext2fs_write_inode, ext2fs_get_blocks,
1618 ext2fs_check_directory):
1619 * get_pathname.c (ext2fs_get_pathname):
1620 * expanddir.c (ext2fs_expand_dir):
1621 * block.c (ext2fs_block_iterate):
1622 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1623 ext2fs_allocate_block_bitmap):
1624 * bb_inode.c (ext2fs_update_bb_inode):
1625 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1626 * check_desc.c (ext2fs_check_desc):
1627 * closefs.c (ext2fs_close, ext2fs_flush):
1628 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1633 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1634 openfs.c into its own file.
1636 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1637 structure magic numbers.
1639 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1640 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1641 someone uses the -b option to specify the use of the backup
1642 superblock --- this usually means that the main superblock is
1646 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1647 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1648 revision level to the superblock.
1650 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1657 * initialize.c: Completely revamped the inode and block bitmap
1658 structures, so that they can be better chance of being extensible
1659 in a shared library. They are now their own type, instead of
1660 being a char *. Also, the function signatures of
1661 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1662 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1663 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1664 changed to eliminate the ext2_filsys argument, since it is no
1667 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1669 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1670 system call if available.
1672 * llseek.c: new file. This is the stub calling the llseek system
1673 call which allows supports for 2GB+ file systems.
1675 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1676 the creator operating system.
1678 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1680 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1681 the group descriptor statistics in addition to everything else.
1682 This relieves mke2fs of the responsibility of doing it.
1684 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1685 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1686 not the generic C function equivalents should be included or not.
1688 * openfs.c (ext2fs_open): If a superblock is specified, then use
1689 the backup group descriptors that go along with this superblock,
1690 instead of using the primary group descriptors. This allows
1691 e2fsck to recover filesystems where the primary group descriptors
