1 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
3 * initialize.c (ext2fs_initialize): Make sure that we allocate
4 enough inodes so that we can make a valid filesystem.
6 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
8 * rw_bitmaps.c: Fixed signed/unsigned warnings.
10 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
13 * dblist.c (make_dblist): Add safety check in case the dblist
14 pointer passed in is null (in which case, assign it to
15 fs->dblist). Fixed some signed/unsigned warnings.
17 * bmap.c: Make addr_per_block be of type blk_t to avoid
18 signed/unsigned warnings.
20 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
23 * get_pathname.c (get_pathname_proc): Use return value from
24 ext2fs_get_mem, instead of checking if &gp->name is
27 * dir_iterate.c (ext2fs_process_dir_block):
28 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
29 from the function declaration.
31 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
32 return the error directly instead of jumping to the
33 cleanup routine, since we don't need to do any cleanup.
35 * alloc_table.c (ext2fs_allocate_group_table): Make this
36 function take a dgrp_t for its group argument.
38 * ext2fs.h: Make dgrp_t an __u32 type, and make
39 fs->desc_group_count be of type dgrp_t.
41 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
43 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
44 than 10 blocks when we need to expand the size of the
47 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
49 * Release of E2fsprogs 1.12
51 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
53 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
54 appropriate for all of the block group copies, so that
55 it's clear where the beginning of the filesystem is on the
56 disk. (For when the partition table gets scrod.)
58 * ext2fs.h: Change the name of the feature from
59 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
60 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
62 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
64 * inode.c (get_next_blockgroup): Fix bug where if
65 get_next_blockgroup() is called early because of a missing
66 inode table in a block group, the current_inode counter
67 wasn't incremented correctly.
69 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
71 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
72 against a completely trashed bad block inode.
74 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
76 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
77 the stride length hits a bad value, we retry the block
78 allocation starting at the beginning of the block group.
80 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
81 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
82 e2_blkcnt_t to avoid collision with LFS API.
84 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
86 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
87 way that avoids overflows on disk sizes greater than 4GB.
89 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
91 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
92 return type for comparison functions for qsort.
94 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
97 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
99 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
102 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
103 evade a potential problem with glibc's header files trying
104 to spike out linux/types.h.
106 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
107 include the old size of the memory, which is needed for
108 some braindamaged memory allocation systems that don't
111 * badblocks.c (ext2fs_badblocks_list_add):
112 bb_inode.c (clear_bad_block_proc):

123 convention. Fix uninstall rules to take $(DESTDIR) into
126 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
128 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
129 with 32 bit longs, then we need to manually define __s64
130 and __u64, since the current kernel header files don't
131 define these if __STRICT_ANSI__ is defined. This is a
132 problem if we are compiling with full GCC warnings, since
133 we do need 64 bit support.
135 * Makefile.in (OBJS): Remove bmove.o from files to be built,
136 since we're not using ext2fs_move_blocks() and there
137 is some question as to its usefulness in its current
140 * bmap.c (block_bmap): Remove unused function.
142 * bmove.c (process_block): Fix -Wall warning.
144 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
146 * block.c (ext2fs_block_iterate3): Make the ref_offset field
147 contain the offset into the inode.i_blocks array when
148 ref_block is zero. Since we haven't done a formal
149 release of e2fsprogs since block_iterate2 was first
150 introduced, I removed block_iterate2, and renamed
151 block_iterate3 to be block_iterate2.
153 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
154 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
155 use of block_iterate and block_iterate2 to
156 block_iterate2 with the new prototype for the
157 interator function. (using blkcnt_t forr blockcount)
159 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
161 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
162 s_prealloc_blocks, s_prealloc_dir_blocks). Added
163 conditional defines of new features COMPAT_DIR_PREALLOC,
164 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
165 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
166 the library to declare that we support COMPAT_DIR_PREALLOC,
167 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
169 * fileio.c: Rename function ext2fs_file_llseek to be
170 ext2fs_file_lseek, which is more accurate.
172 * block.c: Add new function ext2fs_block_iterate3 which calls
173 the iterator function with the blockcount argument of
174 type blkcnt_t. This version of the function is
175 allowed to handle large files; the other fucntions are
178 * ext2fs.h: Add new type blkcnt_t
180 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
182 * block.c (ext2fs_block_iterate2): Fix bug where the block count
183 field wasn't getting correctly incremented for sparse
184 files when the indirect or doubly-indirect block
185 specified in the inode was zero.
187 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
189 * unlink.c (unlink_proc):
190 * lookup.c (lookup_proc):
191 * link.c (link_proc):
192 * get_pathname.c (get_pathname_proc):
193 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
194 from dirent->name_len, so it can be used for other
197 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
198 and indicate that we have support for this incompatible
201 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
203 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

207 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
208 number of directories when the block group information is
211 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
213 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
214 inode table is missing so that we catch the case where the
215 first block group is missing.
217 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
220 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
222 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
224 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
226 * test_io.c (test_flush): Add a debugging printf when the flush
229 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
230 read in, return right away.
232 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
234 * bitops.h: Don't try to do i386 inline asm functions if the
237 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
238 instead of linux/types.h, and e2_bitops.h instead of
241 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
244 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
246 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
247 so that we don't need to call get_next_blockgroup() the
248 first time around. Saves a bit of time, and prevents us
249 from needing to assign -1 to current_group (which is an
252 * icount.c (insert_icount_el): Cast the estimated number of inodes
253 from a float to an ino_t.

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

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

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

408 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
410 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
411 added a new field to the io_channel (app_data).
413 * io.h: Add a new element to the io_channel structure, app_data.

420 * io.h: Change the prototype of ext2fs_llseek() to use int's
421 instead of unsigned int's.
423 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
424 to make life easer for GNU Libc 2.
426 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
427 filesystem has its bitmaps stored as 32-bit words with bit
428 0 as the LSB of each word. Thus a bitmap with only bit 0
429 set would be, as a string of bytes, 00 00 00 01 00 ... To
430 cope with this, we byte-reverse each word of a bitmap if
431 we have a big-endian filesystem, that is, if we are *not*
432 byte-swapping other word-sized numbers.

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

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

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

608 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
610 (unix_close, test_close): Decrement the refcount and only
611 close the io_channel if the refcount goes to 0.
613 * io.h: Add refcount to the io_channel structure. Add new macro
614 interface io_channel_bumpcount() to bump the refcount.
616 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
618 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
619 cache in the filesystem handle, instead of the inode cache
620 in a static variable.
622 * freefs.c: Added static function to free the inode cache (called by
625 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
627 * ext2fs.h: Added pointer to the inode_cache structure.
629 * block.c (block_iterate_ind, block_iterate_dind,
630 block_iterate_tind): If there are holes in the indirect,
631 doubly indirect, or triply indirect blocks, increment the
632 block count field automatically.
634 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
636 * Release of E2fsprogs version 1.09
638 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
640 * version.c (ext2fs_parse_version_string): Check the passed in
641 version string (instead of the hard-coded one).
643 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
644 greater filesystem size, clamp it to prevent allocating a
645 block or inode bitmap beyond the filesystem.
647 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
648 overhead calculation was accidentally removed.
650 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
652 * Release of E2fsprogs version 1.08
654 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
656 * dblist.c (ext2fs_set_dir_block): New function which sets the
657 block of a dblist entry, given the directory inode and
660 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
662 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
663 inode bitmaps at staggered locations across the block
664 groups, to avoid concentrating the bitmaps on a small
665 number of disks when using striped RAID arrays.
667 * initialize.c (ext2fs_initialize): By default, choose the maximum
668 possible number of blocks per group (based on the size of
669 the bitmaps in the blocksize).
671 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
673 * initialize.c (ext2fs_initialize): Add support for
674 EXT2_COMPAT_SPARSE_SUPER feature.
676 * closefs.c (ext2fs_bg_has_super): New function to determine
677 whether or a particular block group should have a
678 superblock and block group descriptor. Used for the
679 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
680 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
681 or not the superblock should be written out for the block
684 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
685 for sparse duplicate superblocks.
687 * version.c (ext2fs_get_library_version): New function which
688 returns the library version.
690 * version.c (ext2fs_parse_version_string): New function which
691 parses a version string and returns a version number,
692 so application programs can compare version numbers as
695 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
697 * icount.c (ext2fs_create_icount): Change function so that it also
698 takes a new argument which contains a "hint" icount
699 structure. This "hint" icount allows the create function
700 to set up the sorted list in advance. This reduces
701 significantly the amount of data moving needed to insert
702 these inodes into the list later.
704 * icount.c (ext2fs_icount_validate): New function which validates
705 that the icount structure's rep invariant.
707 * icount.c (get_icount_el): Completely revamped implementation
708 to subsume put_icount_el(). Put_icount_el() used to
709 use an O(N) implementation to insert in the middle
710 of the icount list. It now uses a O(ln N) to search
711 for where the icount should be inserted, and then uses
712 a memcpy to move the list down (instead of a for loop).
714 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
715 ext2fs_icount_increment, ext2fs_icount_decrement): Check
716 to see if the inode is within bounds; if it isn't, return
719 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
720 when a bad inode number is passed to test_generic_bitmap
721 to be EXT2FS_TEST_ERROR instead of the wrong
724 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
726 * Release of E2fsprogs version 1.07
728 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
730 * Makefile.in (ELF_VERSION): Change version to be 2.2
732 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
734 * alloc.c (ext2fs_get_free_blocks): Change routine to use
735 ext2fs_fast_test_block_bitmap_range().
737 * bitops.h (ext2fs_fast_test_block_bitmap_range,
738 ext2fs_test_block_bitmap_range: New inline functions which
739 test to see whether a contiguous range of blocks is
742 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
744 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
745 use ext2fs_badblocks_* instead of badblocks_*
747 * bb_compat.c: New file which translates between old badblocks_*()
748 names to ext2fs_badblocks_*()
750 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
751 link.c (since e2fsck doesn't use ext2fs_unlink()).
753 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
754 bitmap resizing routine moved from bitmaps.c, since e2fsck
755 doesn't need to use this function.
757 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
758 since e2fsck only needs ext2fs_lookup.
760 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
762 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
763 already set; this is needed so that programs like dump
764 which use the inode scan functions will deal with
765 filesystems that have bad blocks in the inode table.
767 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
769 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
770 Moved to ext2fsP.h, since it doesn't need to be part of
771 the public interface.
773 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
775 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
777 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
778 directory block list abstraction. (Code moved from
781 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
782 to inode.c (since no one else should be peeking inside it!)
784 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
786 * openfs.c (ext2fs_open): Check the feature set in the ext2
787 superblock, and refuse to open filesystems if they contain
788 incompatible features. (Can be overriden with the
791 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
793 * block.c (ext2fs_block_iterate2): Added new function
794 ext2fs_block_iterate2 which changes the function
795 signature of the callback function to include the
796 referencing block and offset.
798 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
799 ext2fs_inode_scan_goto_blockgroup which allows an
800 application to jump to a particular block group while
803 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
805 * dirblock.c: Include string.h, since we use memcpy().
807 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
809 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
810 a long not an int; this doesn't matter on i386 machines,
811 but it does on Alpha's.
813 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
815 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
816 table pointer is NULL, then return an error indicating
817 that the inode table is missing.
818 (get_next_blockgroup, get_next_blocks,
819 ext2fs_get_next_inode): Don't treat a missing inode table
820 as permanent error. Return MISSING_INODE_TABLE, but as an
821 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
823 * rw_bitmaps.c (ext2fs_write_block_bitmap,
824 ext2fs_write_inode_bitmap): If the inode or block bitmap
825 block is zero, then don't write out the inode or block
826 bitmap. The idea here is to avoid stomping on the
828 (read_bitmaps): If the inode or block bitmap block is
829 zero, then fill in that portion of the inode or block
830 bitmap with all zeros.
832 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
833 blocks in inode table when the inode table size is
834 non-standard (and can therefore span blocks).
836 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
838 * alloc.c (ext2fs_new_block): Fix fencepost error in
839 ext2fs_new_block; make sure we don't try to allocate the
840 first block beyond the end of the filesystem.
842 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
844 * inode.c (check_for_inode_bad_blocks): New function called by
845 get_next_blocks() to avoid reading in bad blocks marked in
846 fs->badblocks. Inodes located in bad blocks are returned
847 by ext2fs_get_next_inode() returns the error code
848 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
850 * alloc_tables.c (ext2fs_allocate_tables): New function which
851 performs the part of mke2fs's job of allocating the
854 * test_io.c (test_close): IO manager which is used for testing
857 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
859 * inode.c (ext2fs_get_next_inode): Separate out the function of
860 setting up for a new block group to get_next_blockgroup().
861 Separate out the function of reading in blocks of the
862 inode table to get_next_blocks().
864 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
866 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
867 blocks to the badblock list in sorted order. This allows
868 badblocks_list_test to be coded using a binary search for
871 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
873 * Release of E2fsprogs version 1.06
875 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
877 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
878 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
881 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
882 set, then only write out the master superblock.
884 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
886 * block.c (ext2fs_block_iterate): Fixed bug which caused
887 block_iterate to fail to handle HURD created filesystems;
888 it tested the inode translator field before the inode was
891 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
893 * initialize.c (ext2fs_initialize): Make sure the description for
894 the inode bitmap is set correctly.
896 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

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

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

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

997 Change the m68k bit numbering for bitmasks to match with
998 the bit numbering used by all other ext2 implementations.
1000 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
1002 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

1036 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1037 to avoid conflicts with with kernel include files. Also
1038 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1041 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1043 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1045 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around

1059 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1061 * Makefile.in: Added support for BSD shared libraries.
1063 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1066 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1068 * unix_io.c (unix_open): Add a double check; if the passed in name
1069 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1071 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1073 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>
1075 * inode.c (ext2fs_check_directory): Use LINUX_S_ISDIR instead of
1078 Tue Aug 15 13:08:36 1995 <tytso@rsts-11.mit.edu>
1080 * getsize.c (ext2fs_get_device_size): Add support for reading the
1081 partition size from a BSD disk label.
1083 Thu Aug 10 09:33:26 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1085 * getsize.c (ext2fs_get_device_size): New function that determins
1086 the size of a device. Used by mke2fs and e2fsck.
1088 Sat Aug 12 03:09:54 1995 Remy Card <card@bbj>
1090 * Makefile.in (install): Install static libraries in $(ulibdir)

1095 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1096 Move these functions to freefs.c.
1098 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1099 descriptors shadow memory to keep purify quiet. (This
1100 also has the nice benefit that the unused portion of the
1101 shadow descriptors are zeroed out.)
1103 * dirblock.c (ext2fs_write_dir_block): We need to use
1104 dirent->rec_len *before* it's byteswapped to find the
1105 location of the next directory structure!
1107 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1108 cause ext2fs_new_inode to loop infinitely if we're trying
1109 to allocate an inode in group #0 and there are no free
1110 inodes at all in the system.
1112 * closefs.c: #include <errno.h> if it exists.
1114 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1116 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1122 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1123 installation directories correctly.
1125 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>
1127 * namei.c (process_dir_block):
1128 * mkdir.c (ext2fs_mkdir):
1129 * expanddir.c (expand_dir_proc): Use ext2fs_{read,write}_dir_block
1130 to read/write the directory block.
1132 * dirblock.c (ext2fs_read_dir_block), ext2fs_write_dir_block): New
1133 file containing functions for reading and writing
1134 directory blocks (byte swapping if necesssary)
1136 * block.c (block_iterate_ind, block_iterate_dind,
1137 block_iterate_tind): Byte swap the block addresses if
1138 EXT2_SWAP_BYTES is set (and swap them back before writing
1141 * inode.c (inocpy_with_swap): New function.
1142 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1143 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1145 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1146 the superblock and group descriptors before writing it out.
1148 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1149 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1150 and group descriptors.
1152 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1153 to desp ext2 filesystem structures.
1155 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1156 supplied by Pete A. Zaitcev so that the C language
1157 versions of these functions are more portable. They will
1158 now work on both little and big endian systems, and the
1159 assumption that 32-bit integers are used is gone.
1161 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1162 doing byte swapping.
1164 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1165 byte swapping should take place.
1167 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>
1169 * Makefile.in, cmp_bitmaps.c (ext2fs_compare_block_bitmap_end,
1170 ext2fs_compare_inode_bitmap_end): Added new file
1171 containing routines to compare bitmaps.
1173 * ext2_err.et (EXT2_ET_NEQ_BLOCK_BITMAP, EXT2_ET_NEQ_INODE_BITMAP):
1174 Added new error codes.
1176 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1178 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1179 if the magic number is correct, it will be allocated.
1181 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1183 * block.c (block_iterate_ind, block_iterate_dind,
1184 block_iterate_tind): Don't recompute block_nr each loop;
1185 just increment it! Factor check of BLOCK_FLAG_APPEND out
1186 of the loop. Factor mask of BLOCK_CHANGED into changed
1187 variable out of the loop. (block_iterate_ind, in
1188 particular, gets called a lot, so every little
1189 optimization helps.)
1191 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1193 * block.c (block_iterate_ind, block_iterate_dind,
1194 block_iterate_tind): Precompute limit of loop to speed up
1195 block_iterate_ind and company.
1197 * bitops.h (ext2fs_fast_mark_block_bitmap,
1198 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1199 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1200 ext2fs_fast_test_inode_bitmap): Add fast version of these
1201 functions, which don't do range checking.
1203 * bitops.h (ext2fs_get_block_bitmap_start,
1204 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1205 ext2fs_get_inode_bitmap_end): Add new accessor functions
1206 which return the start and end points of the bitmaps.
1208 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1210 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1211 instead of llseek. The errno if the offset is too large
1212 and lseek is not supported should be EINVAL, not -EINVAL.
1214 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1216 * Makefile.in: Added support for ELF shared libraries.
1217 Fixed typos in the compilation rules.
1218 (distclean): Added Makefile.
1220 * llseek.c (llseek): New function, if llseek() does not exist in the
1222 (ext2_llseek): Changed to call llseek().
1224 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1226 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1228 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1230 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1232 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1233 the S_*, which are normally defined in <sys/stat.h>. This
1234 allows us to compile e2fsprogs on a non-Linux system,
1235 which may have a different value for S_IFDIR.
1237 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1239 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1240 this is a user-mode application!
1242 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1244 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1245 __linux__ so that non-linux systems won't see it.
1247 * alloc.c: Include <errno.h> if possible.
1248 * badblocks.c: Ditto.
1249 * bb_inode.c: Ditto.
1252 * expanddir.c: Ditto.
1253 * get_pathname.c: Ditto.
1254 * initialize.c: Ditto.
1261 * rw_bitmaps.c: Ditto.
1264 * Makefile.in: Rewritten to conform to GNU coding standards and
1265 support separate compilation directories.
1267 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1269 * initialize.c (ext2fs_initialize): Don't allow more than one
1270 bitmaps's worth of inodes in a group.
1272 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1274 * llseek.c (ext2_llseek): Added error checking to the llseek()
1275 compat code to protect against overflow. This only
1276 applies to 1.0 and early 1.1 kernels, which don't support
1277 the llseek() system call.
1279 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1281 * unix_io.c (unix_open): Initialize the read_error and write_error
1282 io_channel pointers to be null.
1284 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1285 found, clear it but don't try to update the filesystem
1286 accounting information, since that's hopeless anyway.
1288 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1289 bloblock_iterate_tind): Check to see if the indirect blocks are
1290 valid before trying to read them.
1292 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1293 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1295 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1296 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1297 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1298 illegal block or inode number is passed in, return instead
1299 of trying to test, set, or clear the bit.
1301 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1303 * Makefile: Added a dummy install target in case shared libraries
1306 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1308 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1309 the real last block of the bitmap should be calculated.
1311 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
1313 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1314 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1315 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1316 ext2fs_free_block_bitmap): Add magic number checking for
1317 the inode and block bitmaps.
1319 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1320 magic number for a block bitmap instead of an inode bitmap.
1322 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1323 magic number checking for the inode_scan structure.
1325 * badblocks.c (badblocks_list_free, badblocks_list_add,
1326 badblocks_list_test, badblocks_list_iterate_begin,
1327 badblocks_list_iterate, badblocks_list_iterate_end): Add
1328 magic number checking for the badblocks_list and
1329 badblocks_iterate structures.
1331 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1332 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1333 unix_write_blk, unix_flush): Add magic number checking
1334 both for io_channel structure and unix_private_data
1337 * openfs.c (ext2fs_open): Add check for io_manager structure's
1340 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1341 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1342 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1343 * read_bb.c (ext2fs_read_bb_inode):
1344 * read_bb_file.c (ext2fs_read_bb_FILE):
1345 * newdir.c (ext2fs_new_dir_block):
1346 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
1347 * link.c (ext2fs_link, ext2fs_unlink):
1348 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,

1353 * block.c (ext2fs_block_iterate):
1354 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1355 ext2fs_allocate_block_bitmap):
1356 * bb_inode.c (ext2fs_update_bb_inode):
1357 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1358 * check_desc.c (ext2fs_check_desc):
1359 * closefs.c (ext2fs_close, ext2fs_flush):
1360 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1365 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1366 openfs.c into its own file.
1368 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1369 structure magic numbers.
1371 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1372 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1373 someone uses the -b option to specify the use of the backup
1374 superblock --- this usually means that the main superblock is
1378 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1379 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1380 revision level to the superblock.
1382 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1389 * initialize.c: Completely revamped the inode and block bitmap
1390 structures, so that they can be better chance of being extensible
1391 in a shared library. They are now their own type, instead of
1392 being a char *. Also, the function signatures of
1393 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1394 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1395 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1396 changed to eliminate the ext2_filsys argument, since it is no
1399 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1401 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1402 system call if available.
1404 * llseek.c: new file. This is the stub calling the llseek system
1405 call which allows supports for 2GB+ file systems.
1407 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1408 the creator operating system.
1410 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1412 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1413 the group descriptor statistics in addition to everything else.
1414 This relieves mke2fs of the responsibility of doing it.
1416 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1417 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1418 not the generic C function equivalents should be included or not.
1420 * openfs.c (ext2fs_open): If a superblock is specified, then use
1421 the backup group descriptors that go along with this superblock,
1422 instead of using the primary group descriptors. This allows
1423 e2fsck to recover filesystems where the primary group descriptors
