1 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
3 * Makefile.in: Updated dependencies.
5 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
7 * initialize.c (ext2fs_initialize): Make sure that we allocate
8 enough inodes so that we can make a valid filesystem.
10 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
12 * rw_bitmaps.c: Fixed signed/unsigned warnings.
14 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
17 * dblist.c (make_dblist): Add safety check in case the dblist
18 pointer passed in is null (in which case, assign it to
19 fs->dblist). Fixed some signed/unsigned warnings.
21 * bmap.c: Make addr_per_block be of type blk_t to avoid
22 signed/unsigned warnings.
24 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
27 * get_pathname.c (get_pathname_proc): Use return value from
28 ext2fs_get_mem, instead of checking if &gp->name is
31 * dir_iterate.c (ext2fs_process_dir_block):
32 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
33 from the function declaration.
35 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
36 return the error directly instead of jumping to the
37 cleanup routine, since we don't need to do any cleanup.
39 * alloc_table.c (ext2fs_allocate_group_table): Make this
40 function take a dgrp_t for its group argument.
42 * ext2fs.h: Make dgrp_t an __u32 type, and make
43 fs->desc_group_count be of type dgrp_t.
45 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
47 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
48 than 10 blocks when we need to expand the size of the
51 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
53 * Release of E2fsprogs 1.12
55 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
57 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
58 appropriate for all of the block group copies, so that
59 it's clear where the beginning of the filesystem is on the
60 disk. (For when the partition table gets scrod.)
62 * ext2fs.h: Change the name of the feature from
63 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
64 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
66 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
68 * inode.c (get_next_blockgroup): Fix bug where if
69 get_next_blockgroup() is called early because of a missing
70 inode table in a block group, the current_inode counter
71 wasn't incremented correctly.
73 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
75 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
76 against a completely trashed bad block inode.
78 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
80 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
81 the stride length hits a bad value, we retry the block
82 allocation starting at the beginning of the block group.
84 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
85 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
86 e2_blkcnt_t to avoid collision with LFS API.
88 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
90 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
91 way that avoids overflows on disk sizes greater than 4GB.
93 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
95 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
96 return type for comparison functions for qsort.
98 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
101 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
103 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
106 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
107 evade a potential problem with glibc's header files trying
108 to spike out linux/types.h.
110 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
111 include the old size of the memory, which is needed for
112 some braindamaged memory allocation systems that don't
115 * badblocks.c (ext2fs_badblocks_list_add):
116 bb_inode.c (clear_bad_block_proc):

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

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

284 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
285 avoid C++ namespace clash.

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

405 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
407 * llseek.c: Added missing semicolon to glibc fixup declaration of

412 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
414 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
415 added a new field to the io_channel (app_data).
417 * io.h: Add a new element to the io_channel structure, app_data.
419 * initialize.c, openfs.c: Set io->app_data to point at the
422 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
424 * io.h: Change the prototype of ext2fs_llseek() to use int's
425 instead of unsigned int's.
427 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
428 to make life easer for GNU Libc 2.
430 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
431 filesystem has its bitmaps stored as 32-bit words with bit
432 0 as the LSB of each word. Thus a bitmap with only bit 0
433 set would be, as a string of bytes, 00 00 00 01 00 ... To
434 cope with this, we byte-reverse each word of a bitmap if
435 we have a big-endian filesystem, that is, if we are *not*
436 byte-swapping other word-sized numbers.

517 the number of directory blocks in dblist.
519 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
521 * unix_io.c (unix_flush): Make the io_channel flush function do a
522 fsync to flush the kernel buffers to disk.

530 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
532 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap

534 to another location in the filesystem.
536 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
537 bitmap, make sure all of the new parts of the bitmap are
540 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
542 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
543 wasn't being returned to the caller.
545 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
546 ext2fs_allocate_group_table() which sets the group tables
547 for a particular block group. The relevant code was
548 factored out of ext2fs_allocate_tables().
550 * dblist.c (make_dblist): Adjust the initial size of the directory
551 block list to be a bit more realistic (ten plus twice the
552 number of directories in the filesystem).
554 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
556 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
557 ext2fs_badblocks_list_test would test the list (and exceed
558 array boundaries) if there were no bad blocks on the bad
559 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
561 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
563 * Release of E2fsprogs version 1.10
565 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
567 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
568 inode and block bitmaps based on the RAID 0 stride
569 parameter (which is passed by mke2fs).
571 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
572 mke2fs to communicate the stride length to
573 ext2fs_allocate_tables()
575 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
577 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
578 systems. (We can't assume that the new filesystem types

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

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

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

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

943 * initialize.c (ext2fs_initialize): On systems where the byte
944 order is not i386 compatible, set the swap_byte flag.
946 * inode.c (inocpy_with_swap): Check to see if inode contains a
947 fast symlink before swapping the inode block fields. This
948 required adding a new argument to inocpy_with_swap to
949 determine whether the mode field is in host order or not.
951 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
953 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
954 the sparc, if EXT2_STD_BITOPS set, use the standard
955 i386-compatible bitmask operations, instead on the
956 non-standard native bitmask operators.
958 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
960 * block.c (ext2fs_block_iterate): Cause block iterator to return
961 the HURD translator block (along with everything else).

964 (including the HURD translator).
966 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
968 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.

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

1001 Change the m68k bit numbering for bitmasks to match with
1002 the bit numbering used by all other ext2 implementations.
1004 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1006 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

1040 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1041 to avoid conflicts with with kernel include files. Also
1042 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1045 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1047 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1049 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around

1061 * closefs.c: #include <string.h> to pick up memset() declaration
1063 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1065 * Makefile.in: Added support for BSD shared libraries.
1067 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1070 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1072 * unix_io.c (unix_open): Add a double check; if the passed in name
1073 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1075 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1077 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
1079 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
1082 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
1084 * getsize.c (ext2fs_get_device_size): Add support for reading the
1085 partition size from a BSD disk label.
1087 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1089 * getsize.c (ext2fs_get_device_size): New function that determins
1090 the size of a device. Used by mke2fs and e2fsck.
1092 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1094 * Makefile.in (install): Install static libraries in $(ulibdir)
1095 (/usr/lib on Linux) instead of $(libdir) (/lib on Linux).
1097 Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o <tytso@dcl>
1099 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1100 Move these functions to freefs.c.
1102 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1103 descriptors shadow memory to keep purify quiet. (This
1104 also has the nice benefit that the unused portion of the
1105 shadow descriptors are zeroed out.)
1107 * dirblock.c (ext2fs_write_dir_block): We need to use
1108 dirent->rec_len *before* it's byteswapped to find the
1109 location of the next directory structure!
1111 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1112 cause ext2fs_new_inode to loop infinitely if we're trying
1113 to allocate an inode in group #0 and there are no free
1114 inodes at all in the system.
1116 * closefs.c: #include <errno.h> if it exists.
1118 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1120 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1126 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1127 installation directories correctly.
1129 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1131 * namei.c (process_dir_block):
1132 * mkdir.c (ext2fs_mkdir):
1133 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1134 to read/write the directory block.
1136 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1137 file containing functions for reading and writing
1138 directory blocks (byte swapping if necesssary)
1140 * block.c (block_iterate_ind, block_iterate_dind,
1141 block_iterate_tind): Byte swap the block addresses if
1142 EXT2_SWAP_BYTES is set (and swap them back before writing
1145 * inode.c (inocpy_with_swap): New function.
1146 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1147 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1149 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1150 the superblock and group descriptors before writing it out.
1152 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1153 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1154 and group descriptors.
1156 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1157 to desp ext2 filesystem structures.
1159 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1160 supplied by Pete A. Zaitcev so that the C language
1161 versions of these functions are more portable. They will
1162 now work on both little and big endian systems, and the
1163 assumption that 32-bit integers are used is gone.
1165 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1166 doing byte swapping.
1168 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1169 byte swapping should take place.
1171 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1173 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
1174 ext2fs_compare_inode_bitmap_end): Added new file
1175 containing routines to compare bitmaps.
1177 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1178 Added new error codes.
1180 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1182 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1183 if the magic number is correct, it will be allocated.
1185 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1187 * block.c (block_iterate_ind, block_iterate_dind,
1188 block_iterate_tind): Don't recompute block_nr each loop;
1189 just increment it! Factor check of BLOCK_FLAG_APPEND out
1190 of the loop. Factor mask of BLOCK_CHANGED into changed
1191 variable out of the loop. (block_iterate_ind, in
1192 particular, gets called a lot, so every little
1193 optimization helps.)
1195 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1197 * block.c (block_iterate_ind, block_iterate_dind,
1198 block_iterate_tind): Precompute limit of loop to speed up
1199 block_iterate_ind and company.
1201 * bitops.h (ext2fs_fast_mark_block_bitmap,
1202 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1203 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1204 ext2fs_fast_test_inode_bitmap): Add fast version of these
1205 functions, which don't do range checking.
1207 * bitops.h (ext2fs_get_block_bitmap_start,
1208 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1209 ext2fs_get_inode_bitmap_end): Add new accessor functions
1210 which return the start and end points of the bitmaps.
1212 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1214 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1215 instead of llseek. The errno if the offset is too large
1216 and lseek is not supported should be EINVAL, not -EINVAL.
1218 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1220 * Makefile.in: Added support for ELF shared libraries.
1221 Fixed typos in the compilation rules.
1222 (distclean): Added Makefile.
1224 * llseek.c (llseek): New function, if llseek() does not exist in the
1226 (ext2_llseek): Changed to call llseek().
1228 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1230 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1232 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1234 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1236 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1237 the S_*, which are normally defined in <sys/stat.h>. This
1238 allows us to compile e2fsprogs on a non-Linux system,
1239 which may have a different value for S_IFDIR.
1241 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1243 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1244 this is a user-mode application!
1246 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1248 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1249 __linux__ so that non-linux systems won't see it.
1251 * alloc.c: Include <errno.h> if possible.
1252 * badblocks.c: Ditto.
1253 * bb_inode.c: Ditto.
1256 * expanddir.c: Ditto.
1257 * get_pathname.c: Ditto.
1258 * initialize.c: Ditto.
1265 * rw_bitmaps.c: Ditto.
1268 * Makefile.in: Rewritten to conform to GNU coding standards and
1269 support separate compilation directories.
1271 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1273 * initialize.c (ext2fs_initialize): Don't allow more than one
1274 bitmaps's worth of inodes in a group.
1276 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1278 * llseek.c (ext2_llseek): Added error checking to the llseek()
1279 compat code to protect against overflow. This only
1280 applies to 1.0 and early 1.1 kernels, which don't support
1281 the llseek() system call.
1283 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1285 * unix_io.c (unix_open): Initialize the read_error and write_error
1286 io_channel pointers to be null.
1288 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1289 found, clear it but don't try to update the filesystem
1290 accounting information, since that's hopeless anyway.
1292 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1293 bloblock_iterate_tind): Check to see if the indirect blocks are
1294 valid before trying to read them.
1296 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1297 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1299 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1300 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1301 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1302 illegal block or inode number is passed in, return instead
1303 of trying to test, set, or clear the bit.
1305 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1307 * Makefile: Added a dummy install target in case shared libraries
1310 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1312 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1313 the real last block of the bitmap should be calculated.
1315 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
1317 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1318 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1319 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1320 ext2fs_free_block_bitmap): Add magic number checking for
1321 the inode and block bitmaps.
1323 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1324 magic number for a block bitmap instead of an inode bitmap.
1326 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1327 magic number checking for the inode_scan structure.
1329 * badblocks.c (badblocks_list_free, badblocks_list_add,
1330 badblocks_list_test, badblocks_list_iterate_begin,
1331 badblocks_list_iterate, badblocks_list_iterate_end): Add
1332 magic number checking for the badblocks_list and
1333 badblocks_iterate structures.
1335 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1336 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1337 unix_write_blk, unix_flush): Add magic number checking
1338 both for io_channel structure and unix_private_data
1341 * openfs.c (ext2fs_open): Add check for io_manager structure's
1344 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1345 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1346 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1347 * read_bb.c (ext2fs_read_bb_inode):
1348 * read_bb_file.c (ext2fs_read_bb_FILE):
1349 * newdir.c (ext2fs_new_dir_block):
1350 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
1351 * link.c (ext2fs_link, ext2fs_unlink):
1352 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

1357 * block.c (ext2fs_block_iterate):
1358 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1359 ext2fs_allocate_block_bitmap):
1360 * bb_inode.c (ext2fs_update_bb_inode):
1361 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1362 * check_desc.c (ext2fs_check_desc):
1363 * closefs.c (ext2fs_close, ext2fs_flush):
1364 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1369 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1370 openfs.c into its own file.
1372 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1373 structure magic numbers.
1375 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1376 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1377 someone uses the -b option to specify the use of the backup
1378 superblock --- this usually means that the main superblock is
1382 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1383 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1384 revision level to the superblock.
1386 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1393 * initialize.c: Completely revamped the inode and block bitmap
1394 structures, so that they can be better chance of being extensible
1395 in a shared library. They are now their own type, instead of
1396 being a char *. Also, the function signatures of
1397 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1398 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1399 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1400 changed to eliminate the ext2_filsys argument, since it is no
1403 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1405 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1406 system call if available.
1408 * llseek.c: new file. This is the stub calling the llseek system
1409 call which allows supports for 2GB+ file systems.
1411 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1412 the creator operating system.
1414 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1416 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1417 the group descriptor statistics in addition to everything else.
1418 This relieves mke2fs of the responsibility of doing it.
1420 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1421 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1422 not the generic C function equivalents should be included or not.
1424 * openfs.c (ext2fs_open): If a superblock is specified, then use
1425 the backup group descriptors that go along with this superblock,
1426 instead of using the primary group descriptors. This allows
1427 e2fsck to recover filesystems where the primary group descriptors
