7 * Makefile.in: Updated dependencies.
9 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
11 * initialize.c (ext2fs_initialize): Make sure that we allocate
12 enough inodes so that we can make a valid filesystem.
14 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
16 * rw_bitmaps.c: Fixed signed/unsigned warnings.
18 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
21 * dblist.c (make_dblist): Add safety check in case the dblist
22 pointer passed in is null (in which case, assign it to
23 fs->dblist). Fixed some signed/unsigned warnings.
25 * bmap.c: Make addr_per_block be of type blk_t to avoid
26 signed/unsigned warnings.
28 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
31 * get_pathname.c (get_pathname_proc): Use return value from
32 ext2fs_get_mem, instead of checking if &gp->name is
35 * dir_iterate.c (ext2fs_process_dir_block):
36 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
37 from the function declaration.
39 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
40 return the error directly instead of jumping to the
41 cleanup routine, since we don't need to do any cleanup.
43 * alloc_table.c (ext2fs_allocate_group_table): Make this
44 function take a dgrp_t for its group argument.
46 * ext2fs.h: Make dgrp_t an __u32 type, and make
47 fs->desc_group_count be of type dgrp_t.
49 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
51 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
52 than 10 blocks when we need to expand the size of the
55 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
57 * Release of E2fsprogs 1.12
59 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
61 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
62 appropriate for all of the block group copies, so that
63 it's clear where the beginning of the filesystem is on the
64 disk. (For when the partition table gets scrod.)
66 * ext2fs.h: Change the name of the feature from
67 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
68 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
70 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
72 * inode.c (get_next_blockgroup): Fix bug where if
73 get_next_blockgroup() is called early because of a missing
74 inode table in a block group, the current_inode counter
75 wasn't incremented correctly.
77 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
79 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
80 against a completely trashed bad block inode.
82 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
84 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
85 the stride length hits a bad value, we retry the block
86 allocation starting at the beginning of the block group.
88 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
89 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
90 e2_blkcnt_t to avoid collision with LFS API.
92 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
94 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
95 way that avoids overflows on disk sizes greater than 4GB.
97 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
99 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
100 return type for comparison functions for qsort.
102 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
105 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
107 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
110 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
111 evade a potential problem with glibc's header files trying
112 to spike out linux/types.h.
114 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
115 include the old size of the memory, which is needed for
116 some braindamaged memory allocation systems that don't
119 * badblocks.c (ext2fs_badblocks_list_add):
120 bb_inode.c (clear_bad_block_proc):
121 dblist.c (ext2fs_add_dir_block):

124 rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to
125 pass the old size of the memory to be resized to
128 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
130 * Makefile.in: Change to use new installation directory variables
131 convention. Fix uninstall rules to take $(DESTDIR) into
134 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
136 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
137 with 32 bit longs, then we need to manually define __s64
138 and __u64, since the current kernel header files don't
139 define these if __STRICT_ANSI__ is defined. This is a
140 problem if we are compiling with full GCC warnings, since
141 we do need 64 bit support.
143 * Makefile.in (OBJS): Remove bmove.o from files to be built,
144 since we're not using ext2fs_move_blocks() and there
145 is some question as to its usefulness in its current
148 * bmap.c (block_bmap): Remove unused function.
150 * bmove.c (process_block): Fix -Wall warning.
152 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
154 * block.c (ext2fs_block_iterate3): Make the ref_offset field
155 contain the offset into the inode.i_blocks array when
156 ref_block is zero. Since we haven't done a formal
157 release of e2fsprogs since block_iterate2 was first
158 introduced, I removed block_iterate2, and renamed
159 block_iterate3 to be block_iterate2.
161 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
162 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
163 use of block_iterate and block_iterate2 to
164 block_iterate2 with the new prototype for the
165 interator function. (using blkcnt_t forr blockcount)
167 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
169 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
170 s_prealloc_blocks, s_prealloc_dir_blocks). Added
171 conditional defines of new features COMPAT_DIR_PREALLOC,
172 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
173 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
174 the library to declare that we support COMPAT_DIR_PREALLOC,
175 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
177 * fileio.c: Rename function ext2fs_file_llseek to be
178 ext2fs_file_lseek, which is more accurate.
180 * block.c: Add new function ext2fs_block_iterate3 which calls
181 the iterator function with the blockcount argument of
182 type blkcnt_t. This version of the function is
183 allowed to handle large files; the other fucntions are
186 * ext2fs.h: Add new type blkcnt_t
188 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
190 * block.c (ext2fs_block_iterate2): Fix bug where the block count
191 field wasn't getting correctly incremented for sparse
192 files when the indirect or doubly-indirect block
193 specified in the inode was zero.
195 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
197 * unlink.c (unlink_proc):
198 * lookup.c (lookup_proc):
199 * link.c (link_proc):
200 * get_pathname.c (get_pathname_proc):
201 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
202 from dirent->name_len, so it can be used for other
205 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
206 and indicate that we have support for this incompatible
209 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
211 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
213 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
215 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
216 number of directories when the block group information is
219 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
221 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
222 inode table is missing so that we catch the case where the
223 first block group is missing.
225 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
228 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
230 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
232 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
234 * test_io.c (test_flush): Add a debugging printf when the flush
237 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
238 read in, return right away.
240 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
242 * bitops.h: Don't try to do i386 inline asm functions if the
245 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
246 instead of linux/types.h, and e2_bitops.h instead of
249 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
252 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
254 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
255 so that we don't need to call get_next_blockgroup() the
256 first time around. Saves a bit of time, and prevents us
257 from needing to assign -1 to current_group (which is an
260 * icount.c (insert_icount_el): Cast the estimated number of inodes
261 from a float to an ino_t.
263 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

273 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
274 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
275 defined, then assume all of the
276 ext2-specific header files are in a flat directory.
278 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
279 all assignments from void * to be compatible with C++.

288 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
289 avoid C++ namespace clash.
291 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to

300 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
302 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
303 paranoid about validating the directory counts from the
304 block group information.
306 * all files: Don't include stdlib.h anymore; include it in
307 ext2_fs.h, since that file requires stdlib.h
309 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
311 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
312 bitmap is loaded, and return an error if it is not.
313 (expand_dir_proc): Only use ext2fs_write_dir_block when
314 writing a directory block, not when writing out a fresh
317 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
319 * Makefile.in, tst_getsize.c: Added new file which is used to test

365 * fileio.c: New file which implements simple file reading and
368 * alloc.c (ext2fs_alloc_block): New function which allocates a
369 block, zeros it, and updates the filesystem accounting
370 records appropriately.

401 * inode.c (ext2fs_check_directory): Add support for the callback
402 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
404 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
406 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
407 padding of the bitmap to be all one's.
409 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
411 * llseek.c: Added missing semicolon to glibc fixup declaration of
414 * bmove.c: Add #include of errno.h
416 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
418 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
419 added a new field to the io_channel (app_data).
421 * io.h: Add a new element to the io_channel structure, app_data.
423 * initialize.c, openfs.c: Set io->app_data to point at the
426 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
428 * io.h: Change the prototype of ext2fs_llseek() to use int's
429 instead of unsigned int's.
431 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
432 to make life easer for GNU Libc 2.
434 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
435 filesystem has its bitmaps stored as 32-bit words with bit
436 0 as the LSB of each word. Thus a bitmap with only bit 0
437 set would be, as a string of bytes, 00 00 00 01 00 ... To
438 cope with this, we byte-reverse each word of a bitmap if
439 we have a big-endian filesystem, that is, if we are *not*
440 byte-swapping other word-sized numbers.
442 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

516 * Release of E2fsprogs 1.11
518 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
520 * dblist.c (ext2fs_dblist_count): Added new function which returns
521 the number of directory blocks in dblist.
523 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
525 * unix_io.c (unix_flush): Make the io_channel flush function do a
526 fsync to flush the kernel buffers to disk.
528 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
530 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
531 current inode number wasn't being set by the
532 goto_blockgroup function.
534 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
536 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
537 of blocks which need to be moved, and moves those blocks
538 to another location in the filesystem.
540 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
541 bitmap, make sure all of the new parts of the bitmap are
544 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
546 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
547 wasn't being returned to the caller.
549 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
550 ext2fs_allocate_group_table() which sets the group tables
551 for a particular block group. The relevant code was
552 factored out of ext2fs_allocate_tables().
554 * dblist.c (make_dblist): Adjust the initial size of the directory
555 block list to be a bit more realistic (ten plus twice the
556 number of directories in the filesystem).
558 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
560 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
561 ext2fs_badblocks_list_test would test the list (and exceed
562 array boundaries) if there were no bad blocks on the bad
563 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
565 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
567 * Release of E2fsprogs version 1.10
569 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
571 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
572 inode and block bitmaps based on the RAID 0 stride
573 parameter (which is passed by mke2fs).
575 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
576 mke2fs to communicate the stride length to
577 ext2fs_allocate_tables()
579 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
581 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
582 systems. (We can't assume that the new filesystem types

593 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
594 filesystem has no free blocks, ext2fs_new_block would loop
597 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
599 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
600 free if refcount goes to zero.

616 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
618 (unix_close, test_close): Decrement the refcount and only
619 close the io_channel if the refcount goes to 0.
621 * io.h: Add refcount to the io_channel structure. Add new macro
622 interface io_channel_bumpcount() to bump the refcount.
624 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
626 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
627 cache in the filesystem handle, instead of the inode cache
628 in a static variable.
630 * freefs.c: Added static function to free the inode cache (called by
633 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
635 * ext2fs.h: Added pointer to the inode_cache structure.
637 * block.c (block_iterate_ind, block_iterate_dind,
638 block_iterate_tind): If there are holes in the indirect,
639 doubly indirect, or triply indirect blocks, increment the
640 block count field automatically.
642 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
644 * Release of E2fsprogs version 1.09
646 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
648 * version.c (ext2fs_parse_version_string): Check the passed in
649 version string (instead of the hard-coded one).
651 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
652 greater filesystem size, clamp it to prevent allocating a
653 block or inode bitmap beyond the filesystem.
655 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
656 overhead calculation was accidentally removed.
658 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
660 * Release of E2fsprogs version 1.08
662 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
664 * dblist.c (ext2fs_set_dir_block): New function which sets the
665 block of a dblist entry, given the directory inode and
668 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
670 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
671 inode bitmaps at staggered locations across the block
672 groups, to avoid concentrating the bitmaps on a small
673 number of disks when using striped RAID arrays.
675 * initialize.c (ext2fs_initialize): By default, choose the maximum
676 possible number of blocks per group (based on the size of
677 the bitmaps in the blocksize).
679 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
681 * initialize.c (ext2fs_initialize): Add support for
682 EXT2_COMPAT_SPARSE_SUPER feature.
684 * closefs.c (ext2fs_bg_has_super): New function to determine
685 whether or a particular block group should have a
686 superblock and block group descriptor. Used for the
687 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
688 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
689 or not the superblock should be written out for the block
692 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
693 for sparse duplicate superblocks.
695 * version.c (ext2fs_get_library_version): New function which
696 returns the library version.
698 * version.c (ext2fs_parse_version_string): New function which
699 parses a version string and returns a version number,
700 so application programs can compare version numbers as
703 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
705 * icount.c (ext2fs_create_icount): Change function so that it also
706 takes a new argument which contains a "hint" icount
707 structure. This "hint" icount allows the create function
708 to set up the sorted list in advance. This reduces
709 significantly the amount of data moving needed to insert
710 these inodes into the list later.
712 * icount.c (ext2fs_icount_validate): New function which validates
713 that the icount structure's rep invariant.
715 * icount.c (get_icount_el): Completely revamped implementation
716 to subsume put_icount_el(). Put_icount_el() used to
717 use an O(N) implementation to insert in the middle
718 of the icount list. It now uses a O(ln N) to search
719 for where the icount should be inserted, and then uses
720 a memcpy to move the list down (instead of a for loop).
722 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
723 ext2fs_icount_increment, ext2fs_icount_decrement): Check
724 to see if the inode is within bounds; if it isn't, return
727 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
728 when a bad inode number is passed to test_generic_bitmap
729 to be EXT2FS_TEST_ERROR instead of the wrong
732 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
734 * Release of E2fsprogs version 1.07
736 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
738 * Makefile.in (ELF_VERSION): Change version to be 2.2
740 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
742 * alloc.c (ext2fs_get_free_blocks): Change routine to use
743 ext2fs_fast_test_block_bitmap_range().
745 * bitops.h (ext2fs_fast_test_block_bitmap_range,
746 ext2fs_test_block_bitmap_range: New inline functions which
747 test to see whether a contiguous range of blocks is
750 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
752 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
753 use ext2fs_badblocks_* instead of badblocks_*
755 * bb_compat.c: New file which translates between old badblocks_*()
756 names to ext2fs_badblocks_*()
758 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
759 link.c (since e2fsck doesn't use ext2fs_unlink()).
761 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
762 bitmap resizing routine moved from bitmaps.c, since e2fsck
763 doesn't need to use this function.
765 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
766 since e2fsck only needs ext2fs_lookup.
768 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
770 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
771 already set; this is needed so that programs like dump
772 which use the inode scan functions will deal with
773 filesystems that have bad blocks in the inode table.
775 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
777 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
778 Moved to ext2fsP.h, since it doesn't need to be part of
779 the public interface.
781 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
783 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
785 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
786 directory block list abstraction. (Code moved from
789 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
790 to inode.c (since no one else should be peeking inside it!)
792 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
794 * openfs.c (ext2fs_open): Check the feature set in the ext2
795 superblock, and refuse to open filesystems if they contain
796 incompatible features. (Can be overriden with the
799 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
801 * block.c (ext2fs_block_iterate2): Added new function
802 ext2fs_block_iterate2 which changes the function
803 signature of the callback function to include the
804 referencing block and offset.
806 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
807 ext2fs_inode_scan_goto_blockgroup which allows an
808 application to jump to a particular block group while
811 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
813 * dirblock.c: Include string.h, since we use memcpy().
815 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
817 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
818 a long not an int; this doesn't matter on i386 machines,
819 but it does on Alpha's.
821 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
823 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
824 table pointer is NULL, then return an error indicating
825 that the inode table is missing.
826 (get_next_blockgroup, get_next_blocks,
827 ext2fs_get_next_inode): Don't treat a missing inode table
828 as permanent error. Return MISSING_INODE_TABLE, but as an
829 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
831 * rw_bitmaps.c (ext2fs_write_block_bitmap,
832 ext2fs_write_inode_bitmap): If the inode or block bitmap
833 block is zero, then don't write out the inode or block
834 bitmap. The idea here is to avoid stomping on the
836 (read_bitmaps): If the inode or block bitmap block is
837 zero, then fill in that portion of the inode or block
838 bitmap with all zeros.
840 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
841 blocks in inode table when the inode table size is
842 non-standard (and can therefore span blocks).
844 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
846 * alloc.c (ext2fs_new_block): Fix fencepost error in
847 ext2fs_new_block; make sure we don't try to allocate the
848 first block beyond the end of the filesystem.
850 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
852 * inode.c (check_for_inode_bad_blocks): New function called by
853 get_next_blocks() to avoid reading in bad blocks marked in
854 fs->badblocks. Inodes located in bad blocks are returned
855 by ext2fs_get_next_inode() returns the error code
856 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
858 * alloc_tables.c (ext2fs_allocate_tables): New function which
859 performs the part of mke2fs's job of allocating the
862 * test_io.c (test_close): IO manager which is used for testing

867 * inode.c (ext2fs_get_next_inode): Separate out the function of
868 setting up for a new block group to get_next_blockgroup().
869 Separate out the function of reading in blocks of the
870 inode table to get_next_blocks().
872 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
874 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
875 blocks to the badblock list in sorted order. This allows
876 badblocks_list_test to be coded using a binary search for
879 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
881 * Release of E2fsprogs version 1.06
883 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
885 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
886 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
889 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
890 set, then only write out the master superblock.
892 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
894 * block.c (ext2fs_block_iterate): Fixed bug which caused
895 block_iterate to fail to handle HURD created filesystems;
896 it tested the inode translator field before the inode was
899 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
901 * initialize.c (ext2fs_initialize): Make sure the description for
902 the inode bitmap is set correctly.
904 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

930 * namei.c (ext2fs_follow_link): New function.
931 (ext2fs_namei): Extended to have support for chasing
932 symbolic links. ext2fs_namei() still returns an inode
933 which is a symbolic link. Symbolic links are only chased
934 while resolving the containing directory. To chase
935 symbolic links of the final result, use
936 ext2fs_follow_link().
938 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
940 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
942 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
943 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

947 * initialize.c (ext2fs_initialize): On systems where the byte
948 order is not i386 compatible, set the swap_byte flag.
950 * inode.c (inocpy_with_swap): Check to see if inode contains a
951 fast symlink before swapping the inode block fields. This
952 required adding a new argument to inocpy_with_swap to
953 determine whether the mode field is in host order or not.
955 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
957 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
958 the sparc, if EXT2_STD_BITOPS set, use the standard
959 i386-compatible bitmask operations, instead on the
960 non-standard native bitmask operators.
962 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
964 * block.c (ext2fs_block_iterate): Cause block iterator to return
965 the HURD translator block (along with everything else).
966 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
967 iterator, then don't return any meta data blocks
968 (including the HURD translator).
970 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
972 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.

984 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
986 * openfs.c (ext2fs_open): If the blocksize in the superblock is
987 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
988 that's a basic value that must be correct for the rest of
991 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
994 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
996 * Release of E2fsprogs version 1.04

1005 Change the m68k bit numbering for bitmasks to match with
1006 the bit numbering used by all other ext2 implementations.
1008 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1010 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

1044 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1045 to avoid conflicts with with kernel include files. Also
1046 rename ADDR and CONST_ADDR to EXT2FS_ADDR and

1053 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1054 s_def_resuid and s_def_resgid for backwards compatibility.
1056 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
1058 * bitops.h: Added #ifdef's for Sparc.
1060 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
1062 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
1065 * closefs.c: #include <string.h> to pick up memset() declaration
1067 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1069 * Makefile.in: Added support for BSD shared libraries.
1071 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1074 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1076 * unix_io.c (unix_open): Add a double check; if the passed in name
1077 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1079 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1081 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
1083 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
1086 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
1088 * getsize.c (ext2fs_get_device_size): Add support for reading the
1089 partition size from a BSD disk label.
1091 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1093 * getsize.c (ext2fs_get_device_size): New function that determins
1094 the size of a device. Used by mke2fs and e2fsck.
1096 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1098 * Makefile.in (install): Install static libraries in $(ulibdir)

1103 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1104 Move these functions to freefs.c.
1106 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1107 descriptors shadow memory to keep purify quiet. (This
1108 also has the nice benefit that the unused portion of the
1109 shadow descriptors are zeroed out.)
1111 * dirblock.c (ext2fs_write_dir_block): We need to use
1112 dirent->rec_len *before* it's byteswapped to find the
1113 location of the next directory structure!
1115 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1116 cause ext2fs_new_inode to loop infinitely if we're trying
1117 to allocate an inode in group #0 and there are no free
1118 inodes at all in the system.
1120 * closefs.c: #include <errno.h> if it exists.
1122 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1124 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1130 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1131 installation directories correctly.
1133 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1135 * namei.c (process_dir_block):
1136 * mkdir.c (ext2fs_mkdir):
1137 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1138 to read/write the directory block.
1140 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1141 file containing functions for reading and writing
1142 directory blocks (byte swapping if necesssary)
1144 * block.c (block_iterate_ind, block_iterate_dind,
1145 block_iterate_tind): Byte swap the block addresses if
1146 EXT2_SWAP_BYTES is set (and swap them back before writing
1149 * inode.c (inocpy_with_swap): New function.
1150 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1151 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1153 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1154 the superblock and group descriptors before writing it out.
1156 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1157 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1158 and group descriptors.
1160 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1161 to desp ext2 filesystem structures.
1163 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1164 supplied by Pete A. Zaitcev so that the C language
1165 versions of these functions are more portable. They will
1166 now work on both little and big endian systems, and the
1167 assumption that 32-bit integers are used is gone.
1169 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1170 doing byte swapping.
1172 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1173 byte swapping should take place.
1175 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1177 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
1178 ext2fs_compare_inode_bitmap_end): Added new file
1179 containing routines to compare bitmaps.
1181 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1182 Added new error codes.
1184 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1186 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1187 if the magic number is correct, it will be allocated.
1189 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1191 * block.c (block_iterate_ind, block_iterate_dind,
1192 block_iterate_tind): Don't recompute block_nr each loop;
1193 just increment it! Factor check of BLOCK_FLAG_APPEND out
1194 of the loop. Factor mask of BLOCK_CHANGED into changed
1195 variable out of the loop. (block_iterate_ind, in
1196 particular, gets called a lot, so every little
1197 optimization helps.)
1199 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1201 * block.c (block_iterate_ind, block_iterate_dind,
1202 block_iterate_tind): Precompute limit of loop to speed up
1203 block_iterate_ind and company.
1205 * bitops.h (ext2fs_fast_mark_block_bitmap,
1206 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1207 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1208 ext2fs_fast_test_inode_bitmap): Add fast version of these
1209 functions, which don't do range checking.
1211 * bitops.h (ext2fs_get_block_bitmap_start,
1212 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1213 ext2fs_get_inode_bitmap_end): Add new accessor functions
1214 which return the start and end points of the bitmaps.
1216 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1218 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1219 instead of llseek. The errno if the offset is too large
1220 and lseek is not supported should be EINVAL, not -EINVAL.
1222 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1224 * Makefile.in: Added support for ELF shared libraries.
1225 Fixed typos in the compilation rules.
1226 (distclean): Added Makefile.
1228 * llseek.c (llseek): New function, if llseek() does not exist in the
1230 (ext2_llseek): Changed to call llseek().
1232 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1234 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1236 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1238 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1240 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1241 the S_*, which are normally defined in <sys/stat.h>. This
1242 allows us to compile e2fsprogs on a non-Linux system,
1243 which may have a different value for S_IFDIR.
1245 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1247 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1248 this is a user-mode application!
1250 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1252 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1253 __linux__ so that non-linux systems won't see it.
1255 * alloc.c: Include <errno.h> if possible.
1256 * badblocks.c: Ditto.
1257 * bb_inode.c: Ditto.
1260 * expanddir.c: Ditto.
1261 * get_pathname.c: Ditto.
1262 * initialize.c: Ditto.
1269 * rw_bitmaps.c: Ditto.
1272 * Makefile.in: Rewritten to conform to GNU coding standards and
1273 support separate compilation directories.
1275 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1277 * initialize.c (ext2fs_initialize): Don't allow more than one
1278 bitmaps's worth of inodes in a group.
1280 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1282 * llseek.c (ext2_llseek): Added error checking to the llseek()
1283 compat code to protect against overflow. This only
1284 applies to 1.0 and early 1.1 kernels, which don't support
1285 the llseek() system call.
1287 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1289 * unix_io.c (unix_open): Initialize the read_error and write_error
1290 io_channel pointers to be null.
1292 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1293 found, clear it but don't try to update the filesystem
1294 accounting information, since that's hopeless anyway.
1296 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1297 bloblock_iterate_tind): Check to see if the indirect blocks are
1298 valid before trying to read them.
1300 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1301 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1303 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1304 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1305 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1306 illegal block or inode number is passed in, return instead
1307 of trying to test, set, or clear the bit.
1309 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1311 * Makefile: Added a dummy install target in case shared libraries
1314 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1316 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1317 the real last block of the bitmap should be calculated.
1319 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
1321 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1322 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1323 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1324 ext2fs_free_block_bitmap): Add magic number checking for
1325 the inode and block bitmaps.
1327 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1328 magic number for a block bitmap instead of an inode bitmap.
1330 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1331 magic number checking for the inode_scan structure.
1333 * badblocks.c (badblocks_list_free, badblocks_list_add,
1334 badblocks_list_test, badblocks_list_iterate_begin,
1335 badblocks_list_iterate, badblocks_list_iterate_end): Add
1336 magic number checking for the badblocks_list and
1337 badblocks_iterate structures.
1339 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1340 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1341 unix_write_blk, unix_flush): Add magic number checking
1342 both for io_channel structure and unix_private_data
1345 * openfs.c (ext2fs_open): Add check for io_manager structure's
1348 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1349 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1350 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1351 * read_bb.c (ext2fs_read_bb_inode):
1352 * read_bb_file.c (ext2fs_read_bb_FILE):
1353 * newdir.c (ext2fs_new_dir_block):
1354 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
1355 * link.c (ext2fs_link, ext2fs_unlink):
1356 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

1361 * block.c (ext2fs_block_iterate):
1362 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1363 ext2fs_allocate_block_bitmap):
1364 * bb_inode.c (ext2fs_update_bb_inode):
1365 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1366 * check_desc.c (ext2fs_check_desc):
1367 * closefs.c (ext2fs_close, ext2fs_flush):
1368 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1373 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1374 openfs.c into its own file.
1376 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1377 structure magic numbers.
1379 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1380 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1381 someone uses the -b option to specify the use of the backup
1382 superblock --- this usually means that the main superblock is
1386 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1387 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1388 revision level to the superblock.
1390 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1397 * initialize.c: Completely revamped the inode and block bitmap
1398 structures, so that they can be better chance of being extensible
1399 in a shared library. They are now their own type, instead of
1400 being a char *. Also, the function signatures of
1401 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1402 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1403 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1404 changed to eliminate the ext2_filsys argument, since it is no
1407 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1409 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1410 system call if available.
1412 * llseek.c: new file. This is the stub calling the llseek system
1413 call which allows supports for 2GB+ file systems.
1415 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1416 the creator operating system.
1418 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1420 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1421 the group descriptor statistics in addition to everything else.
1422 This relieves mke2fs of the responsibility of doing it.
1424 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1425 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1426 not the generic C function equivalents should be included or not.
1428 * openfs.c (ext2fs_open): If a superblock is specified, then use
1429 the backup group descriptors that go along with this superblock,
1430 instead of using the primary group descriptors. This allows
1431 e2fsck to recover filesystems where the primary group descriptors
