5 2000-04-03 Theodore Ts'o <tytso@valinux.com>
7 * block.c: Readibility tweak in conditionals involving
10 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
11 how to define __s64 and __u64. Turn off "compression is
12 experimental" warning if the cpp macro
13 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
15 2000-02-11 <tytso@snap.thunk.org>
17 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.

26 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
27 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
28 Change to return the previous state of the bit that is
29 being marked or unmarked. For speed optimization.
31 2000-02-02 Theodore Ts'o <tytso@valinux.com>
33 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
35 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
36 needed any more; we know it will always be i_generation.
37 Add support for swapping the high bits of the uid and gid.
39 1999-11-19 <tytso@valinux.com>
41 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
42 counts if the link was successful. Patch suggested by

52 1999-11-08 <tytso@valinux.com>
54 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
55 since ext2fs_badblocks_list_free was moved to freefs.c.
57 * tst_badblocks.c: Use the newer badblocks API names. Add
58 duplicate blocks to the test inputs to test dealing with
59 adding blocks which are already in the badblocks list.
61 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
62 of the list, use a shortcut O(1) operations instead of an
63 O(n) operation. (Idea suggested by David Beattie.)
65 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
66 of badblocks_list_free(), to save a procedure call.
68 1999-10-26 <tytso@valinux.com>
70 * Release of E2fsprogs 1.17
72 1999-10-26 <tytso@valinux.com>
74 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
75 seem to handle ~0UL the same way as they used to.
77 1999-10-25 <tytso@valinux.com>
79 * nt_io.c (_OpenNtName): Open the device using
80 FILE_SYNCHRONOUS_IO_NONALERT instead of
81 FILE_SYNCHRONOUS_IO_ALERT
82 (nt_open): At the end of the device open routine, unlock
83 the drive but do not dismount it.
85 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
88 1999-10-22 <tytso@valinux.com>
90 * Release of E2fsprogs 1.16
92 1999-10-22 <tytso@valinux.com>
94 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
96 * link.c (ext2fs_link): This call now uses the low three bits of
97 the flags parameter to pass the directory filetype
98 information; it will set the directory entry FILETYPE
99 information if the filesystem supports it.
101 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
102 option is set, then create the '.' and '..' entries with
103 the filetype set to EXT2_FT_DIR.
105 1999-09-24 <tytso@valinux.com>
107 * nt_io.c: New file which supports I/O under Windows NT.
109 1999-09-07 <tytso@valinux.com>
111 * ext2fs.h: Add new fields for journalling and define new
112 feature bits used by newer filesystems: IMAGIC_INODES,
113 HAS_JOURNAL, RECOVER.
115 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
116 we update the inode block count and size files so that the
117 block count field is updated correctly when we create an
120 1999-07-18 Theodore Ts'o <tytso@valinux.com>
122 * Release of E2fsprogs 1.15
124 1999-06-23 <tytso@valinux.com>
126 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
127 kernels that use i_generation instead of i_version. Patch
128 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
130 1999-06-21 <tytso@valinux.com>
132 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
133 directory entry before calling the callback function.
134 This should prevent some core dumps of insufficiently
135 paranoid callback functions.
137 1999-05-29 <tytso@rsts-11.mit.edu>
139 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
141 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
142 that we don't handle writing yet (we do). Fixed bug where
143 we weren't allocating a big enough buffer for ext2_bmap.
145 1999-05-03 <tytso@rsts-11.mit.edu>
147 * openfs.c (ext2fs_open): Check to make sure that the number of
148 blocks per group is not zero --- if so, it must be a bad
151 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
153 * Release of E2fsprogs 1.14
155 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
157 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
158 the inode number is zero; if it's zero, return
159 EXT2_ET_BAD_INODE_NUM.
161 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
163 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
164 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
167 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
169 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
170 non-Linux case to use EINVAL by default, unless it isn't
171 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
174 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
176 * Release of E2fsprogs 1.13
178 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
180 * Makefile.in: Updated dependencies.
182 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
184 * initialize.c (ext2fs_initialize): Make sure that we allocate
185 enough inodes so that we can make a valid filesystem.
187 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
189 * rw_bitmaps.c: Fixed signed/unsigned warnings.
191 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
192 function declaration.
194 * dblist.c (make_dblist): Add safety check in case the dblist
195 pointer passed in is null (in which case, assign it to
196 fs->dblist). Fixed some signed/unsigned warnings.
198 * bmap.c: Make addr_per_block be of type blk_t to avoid
199 signed/unsigned warnings.
201 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
202 function declaration.
204 * get_pathname.c (get_pathname_proc): Use return value from
205 ext2fs_get_mem, instead of checking if &gp->name is

209 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
210 from the function declaration.
212 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
213 return the error directly instead of jumping to the
214 cleanup routine, since we don't need to do any cleanup.
216 * alloc_table.c (ext2fs_allocate_group_table): Make this
217 function take a dgrp_t for its group argument.
219 * ext2fs.h: Make dgrp_t an __u32 type, and make
220 fs->desc_group_count be of type dgrp_t.
222 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
224 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
225 than 10 blocks when we need to expand the size of the
228 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
230 * Release of E2fsprogs 1.12
232 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
234 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
235 appropriate for all of the block group copies, so that
236 it's clear where the beginning of the filesystem is on the
237 disk. (For when the partition table gets scrod.)
239 * ext2fs.h: Change the name of the feature from
240 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
241 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
243 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
245 * inode.c (get_next_blockgroup): Fix bug where if
246 get_next_blockgroup() is called early because of a missing
247 inode table in a block group, the current_inode counter
248 wasn't incremented correctly.
250 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
252 * read_bb.c (ext2fs_read_bb_inode): Make function more robust

255 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
257 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
258 the stride length hits a bad value, we retry the block
259 allocation starting at the beginning of the block group.
261 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
262 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
263 e2_blkcnt_t to avoid collision with LFS API.
265 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
267 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
268 way that avoids overflows on disk sizes greater than 4GB.
270 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
272 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
273 return type for comparison functions for qsort.
275 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
278 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
280 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
283 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
284 evade a potential problem with glibc's header files trying
285 to spike out linux/types.h.
287 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
288 include the old size of the memory, which is needed for
289 some braindamaged memory allocation systems that don't
292 * badblocks.c (ext2fs_badblocks_list_add):
293 bb_inode.c (clear_bad_block_proc):
294 dblist.c (ext2fs_add_dir_block):

298 pass the old size of the memory to be resized to
301 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
303 * Makefile.in: Change to use new installation directory variables
304 convention. Fix uninstall rules to take $(DESTDIR) into
307 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
309 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
310 with 32 bit longs, then we need to manually define __s64
311 and __u64, since the current kernel header files don't
312 define these if __STRICT_ANSI__ is defined. This is a
313 problem if we are compiling with full GCC warnings, since
314 we do need 64 bit support.
316 * Makefile.in (OBJS): Remove bmove.o from files to be built,
317 since we're not using ext2fs_move_blocks() and there
318 is some question as to its usefulness in its current
321 * bmap.c (block_bmap): Remove unused function.
323 * bmove.c (process_block): Fix -Wall warning.
325 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
327 * block.c (ext2fs_block_iterate3): Make the ref_offset field
328 contain the offset into the inode.i_blocks array when
329 ref_block is zero. Since we haven't done a formal
330 release of e2fsprogs since block_iterate2 was first
331 introduced, I removed block_iterate2, and renamed
332 block_iterate3 to be block_iterate2.
334 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
335 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
336 use of block_iterate and block_iterate2 to
337 block_iterate2 with the new prototype for the
338 interator function. (using blkcnt_t forr blockcount)
340 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
342 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
343 s_prealloc_blocks, s_prealloc_dir_blocks). Added
344 conditional defines of new features COMPAT_DIR_PREALLOC,
345 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
346 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
347 the library to declare that we support COMPAT_DIR_PREALLOC,
348 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
350 * fileio.c: Rename function ext2fs_file_llseek to be
351 ext2fs_file_lseek, which is more accurate.
353 * block.c: Add new function ext2fs_block_iterate3 which calls
354 the iterator function with the blockcount argument of
355 type blkcnt_t. This version of the function is
356 allowed to handle large files; the other fucntions are
359 * ext2fs.h: Add new type blkcnt_t
361 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
363 * block.c (ext2fs_block_iterate2): Fix bug where the block count
364 field wasn't getting correctly incremented for sparse
365 files when the indirect or doubly-indirect block
366 specified in the inode was zero.
368 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
370 * unlink.c (unlink_proc):
371 * lookup.c (lookup_proc):
372 * link.c (link_proc):
373 * get_pathname.c (get_pathname_proc):
374 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
375 from dirent->name_len, so it can be used for other
378 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
379 and indicate that we have support for this incompatible
382 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
384 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

388 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
389 number of directories when the block group information is
392 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
394 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
395 inode table is missing so that we catch the case where the
396 first block group is missing.
398 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
401 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
403 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
405 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
407 * test_io.c (test_flush): Add a debugging printf when the flush
410 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
411 read in, return right away.
413 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
415 * bitops.h: Don't try to do i386 inline asm functions if the
418 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
419 instead of linux/types.h, and e2_bitops.h instead of
422 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
425 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
427 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
428 so that we don't need to call get_next_blockgroup() the
429 first time around. Saves a bit of time, and prevents us
430 from needing to assign -1 to current_group (which is an
433 * icount.c (insert_icount_el): Cast the estimated number of inodes
434 from a float to an ino_t.
436 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

473 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
475 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
476 paranoid about validating the directory counts from the
477 block group information.
479 * all files: Don't include stdlib.h anymore; include it in
480 ext2_fs.h, since that file requires stdlib.h
482 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
484 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
485 bitmap is loaded, and return an error if it is not.
486 (expand_dir_proc): Only use ext2fs_write_dir_block when
487 writing a directory block, not when writing out a fresh
490 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
492 * Makefile.in, tst_getsize.c: Added new file which is used to test

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

579 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
580 padding of the bitmap to be all one's.
582 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
584 * llseek.c: Added missing semicolon to glibc fixup declaration of

599 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
601 * io.h: Change the prototype of ext2fs_llseek() to use int's
602 instead of unsigned int's.
604 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
605 to make life easer for GNU Libc 2.
607 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
608 filesystem has its bitmaps stored as 32-bit words with bit
609 0 as the LSB of each word. Thus a bitmap with only bit 0
610 set would be, as a string of bytes, 00 00 00 01 00 ... To
611 cope with this, we byte-reverse each word of a bitmap if
612 we have a big-endian filesystem, that is, if we are *not*
613 byte-swapping other word-sized numbers.
615 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

679 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
680 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
682 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
684 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
685 is zero, then return EXT2_IO_LLSEEK_FAILED.
687 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
689 * Release of E2fsprogs 1.11
691 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
693 * dblist.c (ext2fs_dblist_count): Added new function which returns
694 the number of directory blocks in dblist.
696 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
698 * unix_io.c (unix_flush): Make the io_channel flush function do a
699 fsync to flush the kernel buffers to disk.
701 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
703 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
704 current inode number wasn't being set by the
705 goto_blockgroup function.
707 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
709 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
710 of blocks which need to be moved, and moves those blocks
711 to another location in the filesystem.
713 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
714 bitmap, make sure all of the new parts of the bitmap are
717 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
719 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
720 wasn't being returned to the caller.
722 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
723 ext2fs_allocate_group_table() which sets the group tables
724 for a particular block group. The relevant code was
725 factored out of ext2fs_allocate_tables().
727 * dblist.c (make_dblist): Adjust the initial size of the directory
728 block list to be a bit more realistic (ten plus twice the
729 number of directories in the filesystem).
731 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
733 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
734 ext2fs_badblocks_list_test would test the list (and exceed
735 array boundaries) if there were no bad blocks on the bad
736 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
738 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
740 * Release of E2fsprogs version 1.10
742 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
744 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
745 inode and block bitmaps based on the RAID 0 stride
746 parameter (which is passed by mke2fs).
748 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
749 mke2fs to communicate the stride length to
750 ext2fs_allocate_tables()
752 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
754 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
755 systems. (We can't assume that the new filesystem types
758 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
760 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
761 allocate the inode and block bitmaps inside block group at
764 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
766 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
767 filesystem has no free blocks, ext2fs_new_block would loop
770 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
772 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
773 free if refcount goes to zero.
775 * inode.c (create_icache): Initialize refcount to 1.
777 * ext2fsP.h: Added refcount to ext2_inode_cache
779 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
782 * badblocks.c (ext2fs_badblocks_copy): New function to copy a

787 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
789 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
791 (unix_close, test_close): Decrement the refcount and only
792 close the io_channel if the refcount goes to 0.
794 * io.h: Add refcount to the io_channel structure. Add new macro
795 interface io_channel_bumpcount() to bump the refcount.
797 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
799 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
800 cache in the filesystem handle, instead of the inode cache
801 in a static variable.
803 * freefs.c: Added static function to free the inode cache (called by
806 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
808 * ext2fs.h: Added pointer to the inode_cache structure.
810 * block.c (block_iterate_ind, block_iterate_dind,
811 block_iterate_tind): If there are holes in the indirect,
812 doubly indirect, or triply indirect blocks, increment the
813 block count field automatically.
815 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
817 * Release of E2fsprogs version 1.09
819 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
821 * version.c (ext2fs_parse_version_string): Check the passed in
822 version string (instead of the hard-coded one).
824 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
825 greater filesystem size, clamp it to prevent allocating a
826 block or inode bitmap beyond the filesystem.
828 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
829 overhead calculation was accidentally removed.
831 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
833 * Release of E2fsprogs version 1.08
835 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
837 * dblist.c (ext2fs_set_dir_block): New function which sets the
838 block of a dblist entry, given the directory inode and
841 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
843 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
844 inode bitmaps at staggered locations across the block
845 groups, to avoid concentrating the bitmaps on a small
846 number of disks when using striped RAID arrays.
848 * initialize.c (ext2fs_initialize): By default, choose the maximum
849 possible number of blocks per group (based on the size of
850 the bitmaps in the blocksize).
852 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
854 * initialize.c (ext2fs_initialize): Add support for
855 EXT2_COMPAT_SPARSE_SUPER feature.
857 * closefs.c (ext2fs_bg_has_super): New function to determine
858 whether or a particular block group should have a
859 superblock and block group descriptor. Used for the
860 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
861 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
862 or not the superblock should be written out for the block
865 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
866 for sparse duplicate superblocks.
868 * version.c (ext2fs_get_library_version): New function which
869 returns the library version.
871 * version.c (ext2fs_parse_version_string): New function which
872 parses a version string and returns a version number,
873 so application programs can compare version numbers as
876 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
878 * icount.c (ext2fs_create_icount): Change function so that it also
879 takes a new argument which contains a "hint" icount
880 structure. This "hint" icount allows the create function
881 to set up the sorted list in advance. This reduces
882 significantly the amount of data moving needed to insert
883 these inodes into the list later.
885 * icount.c (ext2fs_icount_validate): New function which validates
886 that the icount structure's rep invariant.
888 * icount.c (get_icount_el): Completely revamped implementation
889 to subsume put_icount_el(). Put_icount_el() used to
890 use an O(N) implementation to insert in the middle
891 of the icount list. It now uses a O(ln N) to search
892 for where the icount should be inserted, and then uses
893 a memcpy to move the list down (instead of a for loop).
895 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
896 ext2fs_icount_increment, ext2fs_icount_decrement): Check
897 to see if the inode is within bounds; if it isn't, return
900 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
901 when a bad inode number is passed to test_generic_bitmap
902 to be EXT2FS_TEST_ERROR instead of the wrong
905 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
907 * Release of E2fsprogs version 1.07
909 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
911 * Makefile.in (ELF_VERSION): Change version to be 2.2
913 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
915 * alloc.c (ext2fs_get_free_blocks): Change routine to use
916 ext2fs_fast_test_block_bitmap_range().
918 * bitops.h (ext2fs_fast_test_block_bitmap_range,
919 ext2fs_test_block_bitmap_range: New inline functions which
920 test to see whether a contiguous range of blocks is
923 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
925 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
926 use ext2fs_badblocks_* instead of badblocks_*
928 * bb_compat.c: New file which translates between old badblocks_*()
929 names to ext2fs_badblocks_*()
931 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
932 link.c (since e2fsck doesn't use ext2fs_unlink()).
934 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
935 bitmap resizing routine moved from bitmaps.c, since e2fsck
936 doesn't need to use this function.
938 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
939 since e2fsck only needs ext2fs_lookup.
941 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
943 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
944 already set; this is needed so that programs like dump
945 which use the inode scan functions will deal with
946 filesystems that have bad blocks in the inode table.
948 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
950 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
951 Moved to ext2fsP.h, since it doesn't need to be part of
952 the public interface.
954 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
956 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
958 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
959 directory block list abstraction. (Code moved from
962 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
963 to inode.c (since no one else should be peeking inside it!)
965 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
967 * openfs.c (ext2fs_open): Check the feature set in the ext2
968 superblock, and refuse to open filesystems if they contain
969 incompatible features. (Can be overriden with the
972 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
974 * block.c (ext2fs_block_iterate2): Added new function
975 ext2fs_block_iterate2 which changes the function
976 signature of the callback function to include the
977 referencing block and offset.
979 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
980 ext2fs_inode_scan_goto_blockgroup which allows an
981 application to jump to a particular block group while
984 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
986 * dirblock.c: Include string.h, since we use memcpy().
988 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
990 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
991 a long not an int; this doesn't matter on i386 machines,
992 but it does on Alpha's.
994 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
996 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
997 table pointer is NULL, then return an error indicating
998 that the inode table is missing.
999 (get_next_blockgroup, get_next_blocks,
1000 ext2fs_get_next_inode): Don't treat a missing inode table
1001 as permanent error. Return MISSING_INODE_TABLE, but as an
1002 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1004 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1005 ext2fs_write_inode_bitmap): If the inode or block bitmap
1006 block is zero, then don't write out the inode or block
1007 bitmap. The idea here is to avoid stomping on the
1009 (read_bitmaps): If the inode or block bitmap block is
1010 zero, then fill in that portion of the inode or block
1011 bitmap with all zeros.
1013 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1014 blocks in inode table when the inode table size is
1015 non-standard (and can therefore span blocks).
1017 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1019 * alloc.c (ext2fs_new_block): Fix fencepost error in
1020 ext2fs_new_block; make sure we don't try to allocate the
1021 first block beyond the end of the filesystem.
1023 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1025 * inode.c (check_for_inode_bad_blocks): New function called by
1026 get_next_blocks() to avoid reading in bad blocks marked in
1027 fs->badblocks. Inodes located in bad blocks are returned
1028 by ext2fs_get_next_inode() returns the error code
1029 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
1031 * alloc_tables.c (ext2fs_allocate_tables): New function which
1032 performs the part of mke2fs's job of allocating the
1035 * test_io.c (test_close): IO manager which is used for testing
1038 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1040 * inode.c (ext2fs_get_next_inode): Separate out the function of
1041 setting up for a new block group to get_next_blockgroup().
1042 Separate out the function of reading in blocks of the
1043 inode table to get_next_blocks().
1045 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
1047 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1048 blocks to the badblock list in sorted order. This allows
1049 badblocks_list_test to be coded using a binary search for
1052 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1054 * Release of E2fsprogs version 1.06
1056 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1058 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1059 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1062 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1063 set, then only write out the master superblock.
1065 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1067 * block.c (ext2fs_block_iterate): Fixed bug which caused
1068 block_iterate to fail to handle HURD created filesystems;
1069 it tested the inode translator field before the inode was
1072 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1074 * initialize.c (ext2fs_initialize): Make sure the description for
1075 the inode bitmap is set correctly.
1077 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

1103 * namei.c (ext2fs_follow_link): New function.
1104 (ext2fs_namei): Extended to have support for chasing
1105 symbolic links. ext2fs_namei() still returns an inode
1106 which is a symbolic link. Symbolic links are only chased
1107 while resolving the containing directory. To chase
1108 symbolic links of the final result, use
1109 ext2fs_follow_link().
1111 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1120 * initialize.c (ext2fs_initialize): On systems where the byte
1121 order is not i386 compatible, set the swap_byte flag.
1123 * inode.c (inocpy_with_swap): Check to see if inode contains a
1124 fast symlink before swapping the inode block fields. This
1125 required adding a new argument to inocpy_with_swap to
1126 determine whether the mode field is in host order or not.
1128 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1130 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On

1137 * block.c (ext2fs_block_iterate): Cause block iterator to return
1138 the HURD translator block (along with everything else).

1141 (including the HURD translator).
1143 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1145 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1147 * uuid.c: New file, containing UUID utility functions.

1155 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1157 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1159 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1160 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1161 that's a basic value that must be correct for the rest of
1162 the library to work.
1164 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1167 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1178 Change the m68k bit numbering for bitmasks to match with
1179 the bit numbering used by all other ext2 implementations.
1181 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>

1206 when trying to determine its size.
1208 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1210 * Release of E2fsprogs version 1.02

1216 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1217 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1218 to avoid conflicts with with kernel include files. Also
1219 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1222 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1224 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c

1244 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1247 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1249 * unix_io.c (unix_open): Add a double check; if the passed in name
1250 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1252 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1254 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

1276 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1277 Move these functions to freefs.c.
1279 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1280 descriptors shadow memory to keep purify quiet. (This
1281 also has the nice benefit that the unused portion of the
1282 shadow descriptors are zeroed out.)
1284 * dirblock.c (ext2fs_write_dir_block): We need to use
1285 dirent->rec_len *before* it's byteswapped to find the
1286 location of the next directory structure!
1288 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1289 cause ext2fs_new_inode to loop infinitely if we're trying
1290 to allocate an inode in group #0 and there are no free
1291 inodes at all in the system.
1293 * closefs.c: #include <errno.h> if it exists.
1295 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

1314 file containing functions for reading and writing
1315 directory blocks (byte swapping if necesssary)
1317 * block.c (block_iterate_ind, block_iterate_dind,

1327 the superblock and group descriptors before writing it out.
1329 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1330 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1331 and group descriptors.
1333 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1334 to desp ext2 filesystem structures.
1336 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1337 supplied by Pete A. Zaitcev so that the C language
1338 versions of these functions are more portable. They will
1339 now work on both little and big endian systems, and the
1340 assumption that 32-bit integers are used is gone.
1342 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1343 doing byte swapping.
1345 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

1359 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1360 if the magic number is correct, it will be allocated.
1362 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1364 * block.c (block_iterate_ind, block_iterate_dind,
1365 block_iterate_tind): Don't recompute block_nr each loop;
1366 just increment it! Factor check of BLOCK_FLAG_APPEND out
1367 of the loop. Factor mask of BLOCK_CHANGED into changed
1368 variable out of the loop. (block_iterate_ind, in
1369 particular, gets called a lot, so every little
1370 optimization helps.)
1372 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1374 * block.c (block_iterate_ind, block_iterate_dind,

1380 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1381 ext2fs_fast_test_inode_bitmap): Add fast version of these
1382 functions, which don't do range checking.

1386 ext2fs_get_inode_bitmap_end): Add new accessor functions
1387 which return the start and end points of the bitmaps.
1389 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1391 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1392 instead of llseek. The errno if the offset is too large
1393 and lseek is not supported should be EINVAL, not -EINVAL.
1395 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1397 * Makefile.in: Added support for ELF shared libraries.
1398 Fixed typos in the compilation rules.
1399 (distclean): Added Makefile.
1401 * llseek.c (llseek): New function, if llseek() does not exist in the

1413 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1414 the S_*, which are normally defined in <sys/stat.h>. This
1415 allows us to compile e2fsprogs on a non-Linux system,
1416 which may have a different value for S_IFDIR.
1418 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1420 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1421 this is a user-mode application!
1423 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1425 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1426 __linux__ so that non-linux systems won't see it.
1428 * alloc.c: Include <errno.h> if possible.
1429 * badblocks.c: Ditto.
1430 * bb_inode.c: Ditto.
1433 * expanddir.c: Ditto.

1446 support separate compilation directories.
1448 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1450 * initialize.c (ext2fs_initialize): Don't allow more than one
1451 bitmaps's worth of inodes in a group.
1453 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1455 * llseek.c (ext2_llseek): Added error checking to the llseek()
1456 compat code to protect against overflow. This only
1457 applies to 1.0 and early 1.1 kernels, which don't support
1458 the llseek() system call.
1460 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1462 * unix_io.c (unix_open): Initialize the read_error and write_error
1463 io_channel pointers to be null.
1465 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1466 found, clear it but don't try to update the filesystem
1467 accounting information, since that's hopeless anyway.
1469 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1470 bloblock_iterate_tind): Check to see if the indirect blocks are
1471 valid before trying to read them.

1477 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1478 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1479 illegal block or inode number is passed in, return instead
1480 of trying to test, set, or clear the bit.
1482 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1484 * Makefile: Added a dummy install target in case shared libraries

1570 * initialize.c: Completely revamped the inode and block bitmap
1571 structures, so that they can be better chance of being extensible
1572 in a shared library. They are now their own type, instead of
1573 being a char *. Also, the function signatures of

1575 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1576 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were

1582 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1583 system call if available.
1585 * llseek.c: new file. This is the stub calling the llseek system
1586 call which allows supports for 2GB+ file systems.
1588 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1589 the creator operating system.

1593 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1594 the group descriptor statistics in addition to everything else.
1595 This relieves mke2fs of the responsibility of doing it.
1597 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1598 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1599 not the generic C function equivalents should be included or not.
1601 * openfs.c (ext2fs_open): If a superblock is specified, then use
1602 the backup group descriptors that go along with this superblock,
1603 instead of using the primary group descriptors. This allows
1604 e2fsck to recover filesystems where the primary group descriptors
