1 1999-10-26 <tytso@valinux.com>
3 * Release of E2fsprogs 1.17
5 1999-10-26 <tytso@valinux.com>
7 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
8 seem to handle ~0UL the same way as they used to.
10 1999-10-25 <tytso@valinux.com>
12 * nt_io.c (_OpenNtName): Open the device using
13 FILE_SYNCHRONOUS_IO_NONALERT instead of
14 FILE_SYNCHRONOUS_IO_ALERT
15 (nt_open): At the end of the device open routine, unlock
16 the drive but do not dismount it.
18 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
21 1999-10-22 <tytso@valinux.com>
23 * Release of E2fsprogs 1.16
25 1999-10-22 <tytso@valinux.com>
27 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
29 * link.c (ext2fs_link): This call now uses the low three bits of
30 the flags parameter to pass the directory filetype
31 information; it will set the directory entry FILETYPE
32 information if the filesystem supports it.
34 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
35 option is set, then create the '.' and '..' entries with
36 the filetype set to EXT2_FT_DIR.
38 1999-09-24 <tytso@valinux.com>
40 * nt_io.c: New file which supports I/O under Windows NT.
42 1999-09-07 <tytso@valinux.com>
44 * ext2fs.h: Add new fields for journalling and define new
45 feature bits used by newer filesystems: IMAGIC_INODES,
48 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
49 we update the inode block count and size files so that the
50 block count field is updated correctly when we create an
53 1999-07-18 Theodore Ts'o <tytso@valinux.com>
55 * Release of E2fsprogs 1.15
57 1999-06-23 <tytso@valinux.com>
59 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
60 kernels that use i_generation instead of i_version. Patch
61 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
63 1999-06-21 <tytso@valinux.com>
65 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
66 directory entry before calling the callback function.
67 This should prevent some core dumps of insufficiently
68 paranoid callback functions.
70 1999-05-29 <tytso@rsts-11.mit.edu>
72 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
74 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
75 that we don't handle writing yet (we do). Fixed bug where
76 we weren't allocating a big enough buffer for ext2_bmap.
78 1999-05-03 <tytso@rsts-11.mit.edu>
80 * openfs.c (ext2fs_open): Check to make sure that the number of
81 blocks per group is not zero --- if so, it must be a bad
84 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
86 * Release of E2fsprogs 1.14
88 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
90 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
91 the inode number is zero; if it's zero, return
92 EXT2_ET_BAD_INODE_NUM.
94 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
96 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
97 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
100 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
102 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
103 non-Linux case to use EINVAL by default, unless it isn't
104 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
107 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
109 * Release of E2fsprogs 1.13
111 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
113 * Makefile.in: Updated dependencies.
115 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
117 * initialize.c (ext2fs_initialize): Make sure that we allocate
118 enough inodes so that we can make a valid filesystem.
120 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
122 * rw_bitmaps.c: Fixed signed/unsigned warnings.
124 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
125 function declaration.
127 * dblist.c (make_dblist): Add safety check in case the dblist
128 pointer passed in is null (in which case, assign it to
129 fs->dblist). Fixed some signed/unsigned warnings.
131 * bmap.c: Make addr_per_block be of type blk_t to avoid
132 signed/unsigned warnings.
134 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
135 function declaration.
137 * get_pathname.c (get_pathname_proc): Use return value from
138 ext2fs_get_mem, instead of checking if &gp->name is

142 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
143 from the function declaration.
145 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
146 return the error directly instead of jumping to the
147 cleanup routine, since we don't need to do any cleanup.
149 * alloc_table.c (ext2fs_allocate_group_table): Make this
150 function take a dgrp_t for its group argument.
152 * ext2fs.h: Make dgrp_t an __u32 type, and make
153 fs->desc_group_count be of type dgrp_t.
155 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
157 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
158 than 10 blocks when we need to expand the size of the
161 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
163 * Release of E2fsprogs 1.12
165 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
167 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
168 appropriate for all of the block group copies, so that
169 it's clear where the beginning of the filesystem is on the
170 disk. (For when the partition table gets scrod.)
172 * ext2fs.h: Change the name of the feature from
173 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
174 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
176 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
178 * inode.c (get_next_blockgroup): Fix bug where if
179 get_next_blockgroup() is called early because of a missing
180 inode table in a block group, the current_inode counter
181 wasn't incremented correctly.
183 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
185 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
186 against a completely trashed bad block inode.
188 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
190 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
191 the stride length hits a bad value, we retry the block
192 allocation starting at the beginning of the block group.
194 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
195 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
196 e2_blkcnt_t to avoid collision with LFS API.
198 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
200 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
201 way that avoids overflows on disk sizes greater than 4GB.
203 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
205 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
206 return type for comparison functions for qsort.
208 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
211 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
213 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
216 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
217 evade a potential problem with glibc's header files trying
218 to spike out linux/types.h.
220 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
221 include the old size of the memory, which is needed for
222 some braindamaged memory allocation systems that don't
225 * badblocks.c (ext2fs_badblocks_list_add):
226 bb_inode.c (clear_bad_block_proc):

237 convention. Fix uninstall rules to take $(DESTDIR) into
240 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
242 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
243 with 32 bit longs, then we need to manually define __s64
244 and __u64, since the current kernel header files don't
245 define these if __STRICT_ANSI__ is defined. This is a
246 problem if we are compiling with full GCC warnings, since
247 we do need 64 bit support.
249 * Makefile.in (OBJS): Remove bmove.o from files to be built,
250 since we're not using ext2fs_move_blocks() and there
251 is some question as to its usefulness in its current
254 * bmap.c (block_bmap): Remove unused function.
256 * bmove.c (process_block): Fix -Wall warning.
258 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
260 * block.c (ext2fs_block_iterate3): Make the ref_offset field
261 contain the offset into the inode.i_blocks array when
262 ref_block is zero. Since we haven't done a formal
263 release of e2fsprogs since block_iterate2 was first
264 introduced, I removed block_iterate2, and renamed
265 block_iterate3 to be block_iterate2.
267 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
268 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
269 use of block_iterate and block_iterate2 to
270 block_iterate2 with the new prototype for the
271 interator function. (using blkcnt_t forr blockcount)
273 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
275 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
276 s_prealloc_blocks, s_prealloc_dir_blocks). Added
277 conditional defines of new features COMPAT_DIR_PREALLOC,
278 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
279 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
280 the library to declare that we support COMPAT_DIR_PREALLOC,
281 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
283 * fileio.c: Rename function ext2fs_file_llseek to be
284 ext2fs_file_lseek, which is more accurate.
286 * block.c: Add new function ext2fs_block_iterate3 which calls
287 the iterator function with the blockcount argument of
288 type blkcnt_t. This version of the function is
289 allowed to handle large files; the other fucntions are
292 * ext2fs.h: Add new type blkcnt_t
294 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
296 * block.c (ext2fs_block_iterate2): Fix bug where the block count
297 field wasn't getting correctly incremented for sparse
298 files when the indirect or doubly-indirect block
299 specified in the inode was zero.
301 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
303 * unlink.c (unlink_proc):
304 * lookup.c (lookup_proc):
305 * link.c (link_proc):
306 * get_pathname.c (get_pathname_proc):
307 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
308 from dirent->name_len, so it can be used for other
311 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
312 and indicate that we have support for this incompatible
315 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
317 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

321 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
322 number of directories when the block group information is
325 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
327 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
328 inode table is missing so that we catch the case where the
329 first block group is missing.
331 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
334 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
336 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
338 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
340 * test_io.c (test_flush): Add a debugging printf when the flush
343 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
344 read in, return right away.
346 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
348 * bitops.h: Don't try to do i386 inline asm functions if the
351 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
352 instead of linux/types.h, and e2_bitops.h instead of
355 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
358 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
360 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
361 so that we don't need to call get_next_blockgroup() the
362 first time around. Saves a bit of time, and prevents us
363 from needing to assign -1 to current_group (which is an
366 * icount.c (insert_icount_el): Cast the estimated number of inodes
367 from a float to an ino_t.
369 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

379 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
380 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
381 defined, then assume all of the
382 ext2-specific header files are in a flat directory.
384 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
385 all assignments from void * to be compatible with C++.

406 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
408 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
409 paranoid about validating the directory counts from the
410 block group information.
412 * all files: Don't include stdlib.h anymore; include it in
413 ext2_fs.h, since that file requires stdlib.h
415 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
417 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
418 bitmap is loaded, and return an error if it is not.
419 (expand_dir_proc): Only use ext2fs_write_dir_block when
420 writing a directory block, not when writing out a fresh
423 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
425 * Makefile.in, tst_getsize.c: Added new file which is used to test

471 * fileio.c: New file which implements simple file reading and
474 * alloc.c (ext2fs_alloc_block): New function which allocates a
475 block, zeros it, and updates the filesystem accounting
476 records appropriately.

512 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
513 padding of the bitmap to be all one's.
515 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
517 * llseek.c: Added missing semicolon to glibc fixup declaration of
520 * bmove.c: Add #include of errno.h
522 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
524 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
525 added a new field to the io_channel (app_data).
527 * io.h: Add a new element to the io_channel structure, app_data.
529 * initialize.c, openfs.c: Set io->app_data to point at the
532 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
534 * io.h: Change the prototype of ext2fs_llseek() to use int's
535 instead of unsigned int's.
537 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
538 to make life easer for GNU Libc 2.
540 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
541 filesystem has its bitmaps stored as 32-bit words with bit
542 0 as the LSB of each word. Thus a bitmap with only bit 0
543 set would be, as a string of bytes, 00 00 00 01 00 ... To
544 cope with this, we byte-reverse each word of a bitmap if
545 we have a big-endian filesystem, that is, if we are *not*
546 byte-swapping other word-sized numbers.

615 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
617 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
618 is zero, then return EXT2_IO_LLSEEK_FAILED.
620 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
622 * Release of E2fsprogs 1.11
624 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

627 the number of directory blocks in dblist.
629 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
631 * unix_io.c (unix_flush): Make the io_channel flush function do a
632 fsync to flush the kernel buffers to disk.
634 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
636 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
637 current inode number wasn't being set by the
638 goto_blockgroup function.
640 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
642 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
643 of blocks which need to be moved, and moves those blocks
644 to another location in the filesystem.
646 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
647 bitmap, make sure all of the new parts of the bitmap are
650 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
652 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
653 wasn't being returned to the caller.
655 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
656 ext2fs_allocate_group_table() which sets the group tables
657 for a particular block group. The relevant code was
658 factored out of ext2fs_allocate_tables().
660 * dblist.c (make_dblist): Adjust the initial size of the directory
661 block list to be a bit more realistic (ten plus twice the
662 number of directories in the filesystem).
664 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
666 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
667 ext2fs_badblocks_list_test would test the list (and exceed
668 array boundaries) if there were no bad blocks on the bad
669 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
671 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
673 * Release of E2fsprogs version 1.10
675 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
677 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
678 inode and block bitmaps based on the RAID 0 stride
679 parameter (which is passed by mke2fs).
681 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
682 mke2fs to communicate the stride length to
683 ext2fs_allocate_tables()
685 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
687 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
688 systems. (We can't assume that the new filesystem types

722 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
724 (unix_close, test_close): Decrement the refcount and only
725 close the io_channel if the refcount goes to 0.
727 * io.h: Add refcount to the io_channel structure. Add new macro
728 interface io_channel_bumpcount() to bump the refcount.
730 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
732 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
733 cache in the filesystem handle, instead of the inode cache
734 in a static variable.
736 * freefs.c: Added static function to free the inode cache (called by
739 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
741 * ext2fs.h: Added pointer to the inode_cache structure.
743 * block.c (block_iterate_ind, block_iterate_dind,
744 block_iterate_tind): If there are holes in the indirect,
745 doubly indirect, or triply indirect blocks, increment the
746 block count field automatically.
748 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
750 * Release of E2fsprogs version 1.09
752 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
754 * version.c (ext2fs_parse_version_string): Check the passed in
755 version string (instead of the hard-coded one).
757 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
758 greater filesystem size, clamp it to prevent allocating a
759 block or inode bitmap beyond the filesystem.
761 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
762 overhead calculation was accidentally removed.
764 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
766 * Release of E2fsprogs version 1.08
768 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
770 * dblist.c (ext2fs_set_dir_block): New function which sets the
771 block of a dblist entry, given the directory inode and
774 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
776 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
777 inode bitmaps at staggered locations across the block
778 groups, to avoid concentrating the bitmaps on a small
779 number of disks when using striped RAID arrays.
781 * initialize.c (ext2fs_initialize): By default, choose the maximum
782 possible number of blocks per group (based on the size of
783 the bitmaps in the blocksize).
785 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
787 * initialize.c (ext2fs_initialize): Add support for
788 EXT2_COMPAT_SPARSE_SUPER feature.
790 * closefs.c (ext2fs_bg_has_super): New function to determine
791 whether or a particular block group should have a
792 superblock and block group descriptor. Used for the
793 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
794 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
795 or not the superblock should be written out for the block
798 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
799 for sparse duplicate superblocks.
801 * version.c (ext2fs_get_library_version): New function which
802 returns the library version.
804 * version.c (ext2fs_parse_version_string): New function which
805 parses a version string and returns a version number,
806 so application programs can compare version numbers as
809 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
811 * icount.c (ext2fs_create_icount): Change function so that it also
812 takes a new argument which contains a "hint" icount
813 structure. This "hint" icount allows the create function
814 to set up the sorted list in advance. This reduces
815 significantly the amount of data moving needed to insert
816 these inodes into the list later.
818 * icount.c (ext2fs_icount_validate): New function which validates
819 that the icount structure's rep invariant.
821 * icount.c (get_icount_el): Completely revamped implementation
822 to subsume put_icount_el(). Put_icount_el() used to
823 use an O(N) implementation to insert in the middle
824 of the icount list. It now uses a O(ln N) to search
825 for where the icount should be inserted, and then uses
826 a memcpy to move the list down (instead of a for loop).
828 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
829 ext2fs_icount_increment, ext2fs_icount_decrement): Check
830 to see if the inode is within bounds; if it isn't, return
833 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
834 when a bad inode number is passed to test_generic_bitmap
835 to be EXT2FS_TEST_ERROR instead of the wrong
838 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
840 * Release of E2fsprogs version 1.07
842 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
844 * Makefile.in (ELF_VERSION): Change version to be 2.2
846 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
848 * alloc.c (ext2fs_get_free_blocks): Change routine to use
849 ext2fs_fast_test_block_bitmap_range().
851 * bitops.h (ext2fs_fast_test_block_bitmap_range,
852 ext2fs_test_block_bitmap_range: New inline functions which
853 test to see whether a contiguous range of blocks is
856 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
858 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
859 use ext2fs_badblocks_* instead of badblocks_*
861 * bb_compat.c: New file which translates between old badblocks_*()
862 names to ext2fs_badblocks_*()
864 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
865 link.c (since e2fsck doesn't use ext2fs_unlink()).
867 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
868 bitmap resizing routine moved from bitmaps.c, since e2fsck
869 doesn't need to use this function.
871 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
872 since e2fsck only needs ext2fs_lookup.
874 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
876 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
877 already set; this is needed so that programs like dump
878 which use the inode scan functions will deal with
879 filesystems that have bad blocks in the inode table.
881 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
883 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
884 Moved to ext2fsP.h, since it doesn't need to be part of
885 the public interface.
887 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
889 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
891 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
892 directory block list abstraction. (Code moved from
895 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
896 to inode.c (since no one else should be peeking inside it!)
898 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
900 * openfs.c (ext2fs_open): Check the feature set in the ext2
901 superblock, and refuse to open filesystems if they contain
902 incompatible features. (Can be overriden with the
905 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
907 * block.c (ext2fs_block_iterate2): Added new function
908 ext2fs_block_iterate2 which changes the function
909 signature of the callback function to include the
910 referencing block and offset.
912 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
913 ext2fs_inode_scan_goto_blockgroup which allows an
914 application to jump to a particular block group while
917 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
919 * dirblock.c: Include string.h, since we use memcpy().
921 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
923 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
924 a long not an int; this doesn't matter on i386 machines,
925 but it does on Alpha's.
927 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
929 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
930 table pointer is NULL, then return an error indicating
931 that the inode table is missing.
932 (get_next_blockgroup, get_next_blocks,
933 ext2fs_get_next_inode): Don't treat a missing inode table
934 as permanent error. Return MISSING_INODE_TABLE, but as an
935 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
937 * rw_bitmaps.c (ext2fs_write_block_bitmap,
938 ext2fs_write_inode_bitmap): If the inode or block bitmap
939 block is zero, then don't write out the inode or block
940 bitmap. The idea here is to avoid stomping on the
942 (read_bitmaps): If the inode or block bitmap block is
943 zero, then fill in that portion of the inode or block
944 bitmap with all zeros.
946 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
947 blocks in inode table when the inode table size is
948 non-standard (and can therefore span blocks).
950 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
952 * alloc.c (ext2fs_new_block): Fix fencepost error in
953 ext2fs_new_block; make sure we don't try to allocate the
954 first block beyond the end of the filesystem.
956 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
958 * inode.c (check_for_inode_bad_blocks): New function called by
959 get_next_blocks() to avoid reading in bad blocks marked in
960 fs->badblocks. Inodes located in bad blocks are returned
961 by ext2fs_get_next_inode() returns the error code
962 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
964 * alloc_tables.c (ext2fs_allocate_tables): New function which
965 performs the part of mke2fs's job of allocating the
968 * test_io.c (test_close): IO manager which is used for testing
971 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
973 * inode.c (ext2fs_get_next_inode): Separate out the function of
974 setting up for a new block group to get_next_blockgroup().
975 Separate out the function of reading in blocks of the
976 inode table to get_next_blocks().
978 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
980 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
981 blocks to the badblock list in sorted order. This allows
982 badblocks_list_test to be coded using a binary search for
985 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
987 * Release of E2fsprogs version 1.06
989 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
991 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
992 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
995 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
996 set, then only write out the master superblock.
998 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1000 * block.c (ext2fs_block_iterate): Fixed bug which caused
1001 block_iterate to fail to handle HURD created filesystems;
1002 it tested the inode translator field before the inode was
1005 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1007 * initialize.c (ext2fs_initialize): Make sure the description for
1008 the inode bitmap is set correctly.
1010 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

1014 * Release of E2fsprogs version 1.05
1016 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1018 * initialize.c: Override the kernel's idea of default
1019 checkinterval from 0 (never) to 180 days.
1021 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1023 * namei.c (ext2fs_namei_follow): New function which follows

1028 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
1029 for shortcut function fs->read_inode() and fs->write_inode().
1030 Added inode_cache to reduce CPU time spent in doing
1033 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
1036 * namei.c (ext2fs_follow_link): New function.
1037 (ext2fs_namei): Extended to have support for chasing
1038 symbolic links. ext2fs_namei() still returns an inode
1039 which is a symbolic link. Symbolic links are only chased
1040 while resolving the containing directory. To chase
1041 symbolic links of the final result, use
1042 ext2fs_follow_link().
1044 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1046 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1048 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1049 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
1051 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1053 * initialize.c (ext2fs_initialize): On systems where the byte
1054 order is not i386 compatible, set the swap_byte flag.
1056 * inode.c (inocpy_with_swap): Check to see if inode contains a
1057 fast symlink before swapping the inode block fields. This
1058 required adding a new argument to inocpy_with_swap to
1059 determine whether the mode field is in host order or not.
1061 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1063 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1064 the sparc, if EXT2_STD_BITOPS set, use the standard
1065 i386-compatible bitmask operations, instead on the

1074 (including the HURD translator).
1076 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1078 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1080 * uuid.c: New file, containing UUID utility functions.
1082 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1084 * ext2fs.h: Add a definition of the "real" ext2 superblock.

1090 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1092 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1093 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1094 that's a basic value that must be correct for the rest of
1095 the library to work.
1097 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1100 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1148 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1149 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1150 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1151 to avoid conflicts with with kernel include files. Also
1152 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1155 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1157 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1159 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1160 s_def_resuid and s_def_resgid for backwards compatibility.
1162 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

1175 * Makefile.in: Added support for BSD shared libraries.
1177 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1180 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1182 * unix_io.c (unix_open): Add a double check; if the passed in name
1183 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1185 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1187 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

1209 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1210 Move these functions to freefs.c.
1212 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1213 descriptors shadow memory to keep purify quiet. (This
1214 also has the nice benefit that the unused portion of the
1215 shadow descriptors are zeroed out.)
1217 * dirblock.c (ext2fs_write_dir_block): We need to use
1218 dirent->rec_len *before* it's byteswapped to find the
1219 location of the next directory structure!
1221 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1222 cause ext2fs_new_inode to loop infinitely if we're trying
1223 to allocate an inode in group #0 and there are no free
1224 inodes at all in the system.
1226 * closefs.c: #include <errno.h> if it exists.
1228 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1230 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1247 file containing functions for reading and writing
1248 directory blocks (byte swapping if necesssary)
1250 * block.c (block_iterate_ind, block_iterate_dind,
1251 block_iterate_tind): Byte swap the block addresses if
1252 EXT2_SWAP_BYTES is set (and swap them back before writing
1255 * inode.c (inocpy_with_swap): New function.
1256 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1257 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1259 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1260 the superblock and group descriptors before writing it out.
1262 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1263 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1264 and group descriptors.
1266 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1267 to desp ext2 filesystem structures.
1269 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1270 supplied by Pete A. Zaitcev so that the C language
1271 versions of these functions are more portable. They will
1272 now work on both little and big endian systems, and the
1273 assumption that 32-bit integers are used is gone.
1275 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1276 doing byte swapping.
1278 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1279 byte swapping should take place.
1281 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

1292 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1293 if the magic number is correct, it will be allocated.
1295 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1297 * block.c (block_iterate_ind, block_iterate_dind,
1298 block_iterate_tind): Don't recompute block_nr each loop;
1299 just increment it! Factor check of BLOCK_FLAG_APPEND out
1300 of the loop. Factor mask of BLOCK_CHANGED into changed
1301 variable out of the loop. (block_iterate_ind, in
1302 particular, gets called a lot, so every little
1303 optimization helps.)
1305 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1307 * block.c (block_iterate_ind, block_iterate_dind,

1309 block_iterate_ind and company.
1311 * bitops.h (ext2fs_fast_mark_block_bitmap,
1312 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1313 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1314 ext2fs_fast_test_inode_bitmap): Add fast version of these
1315 functions, which don't do range checking.
1317 * bitops.h (ext2fs_get_block_bitmap_start,
1318 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1319 ext2fs_get_inode_bitmap_end): Add new accessor functions
1320 which return the start and end points of the bitmaps.
1322 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1324 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1325 instead of llseek. The errno if the offset is too large
1326 and lseek is not supported should be EINVAL, not -EINVAL.
1328 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1330 * Makefile.in: Added support for ELF shared libraries.
1331 Fixed typos in the compilation rules.
1332 (distclean): Added Makefile.

1338 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1340 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1342 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1344 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1346 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1347 the S_*, which are normally defined in <sys/stat.h>. This
1348 allows us to compile e2fsprogs on a non-Linux system,
1349 which may have a different value for S_IFDIR.
1351 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1353 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1354 this is a user-mode application!
1356 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1358 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1359 __linux__ so that non-linux systems won't see it.
1361 * alloc.c: Include <errno.h> if possible.
1362 * badblocks.c: Ditto.
1363 * bb_inode.c: Ditto.
1366 * expanddir.c: Ditto.
1367 * get_pathname.c: Ditto.
1368 * initialize.c: Ditto.
1375 * rw_bitmaps.c: Ditto.
1378 * Makefile.in: Rewritten to conform to GNU coding standards and
1379 support separate compilation directories.
1381 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1383 * initialize.c (ext2fs_initialize): Don't allow more than one
1384 bitmaps's worth of inodes in a group.
1386 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1388 * llseek.c (ext2_llseek): Added error checking to the llseek()
1389 compat code to protect against overflow. This only
1390 applies to 1.0 and early 1.1 kernels, which don't support
1391 the llseek() system call.
1393 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1395 * unix_io.c (unix_open): Initialize the read_error and write_error
1396 io_channel pointers to be null.
1398 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1399 found, clear it but don't try to update the filesystem
1400 accounting information, since that's hopeless anyway.
1402 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1403 bloblock_iterate_tind): Check to see if the indirect blocks are
1404 valid before trying to read them.

1407 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1409 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1410 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1411 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1412 illegal block or inode number is passed in, return instead
1413 of trying to test, set, or clear the bit.
1415 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1417 * Makefile: Added a dummy install target in case shared libraries

1428 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1429 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,

1431 the inode and block bitmaps.
1433 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1434 magic number for a block bitmap instead of an inode bitmap.

1441 badblocks_list_iterate, badblocks_list_iterate_end): Add
1442 magic number checking for the badblocks_list and
1443 badblocks_iterate structures.
1445 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1446 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1447 unix_write_blk, unix_flush): Add magic number checking
1448 both for io_channel structure and unix_private_data
1451 * openfs.c (ext2fs_open): Add check for io_manager structure's
1454 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1455 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1456 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1457 * read_bb.c (ext2fs_read_bb_inode):
1458 * read_bb_file.c (ext2fs_read_bb_FILE):

1469 ext2fs_allocate_block_bitmap):
1470 * bb_inode.c (ext2fs_update_bb_inode):
1471 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1472 * check_desc.c (ext2fs_check_desc):
1473 * closefs.c (ext2fs_close, ext2fs_flush):
1474 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1479 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1480 openfs.c into its own file.
1482 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1483 structure magic numbers.
1485 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1486 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1487 someone uses the -b option to specify the use of the backup
1488 superblock --- this usually means that the main superblock is
1492 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1493 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1494 revision level to the superblock.
1496 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1503 * initialize.c: Completely revamped the inode and block bitmap
1504 structures, so that they can be better chance of being extensible
1505 in a shared library. They are now their own type, instead of
1506 being a char *. Also, the function signatures of
1507 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1508 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1509 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1510 changed to eliminate the ext2_filsys argument, since it is no
1513 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1515 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1516 system call if available.
1518 * llseek.c: new file. This is the stub calling the llseek system
1519 call which allows supports for 2GB+ file systems.

1522 the creator operating system.
1524 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1526 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1527 the group descriptor statistics in addition to everything else.
1528 This relieves mke2fs of the responsibility of doing it.
1530 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1531 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1532 not the generic C function equivalents should be included or not.
1534 * openfs.c (ext2fs_open): If a superblock is specified, then use
1535 the backup group descriptors that go along with this superblock,
1536 instead of using the primary group descriptors. This allows
1537 e2fsck to recover filesystems where the primary group descriptors
