Raw Blame History

Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
* Release of E2fsprogs version 1.07
Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Makefile.in (ELF_VERSION): Change version to be 2.2
Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* alloc.c (ext2fs_get_free_blocks): Change routine to use
ext2fs_fast_test_block_bitmap_range().
* bitops.h (ext2fs_fast_test_block_bitmap_range,
ext2fs_test_block_bitmap_range: New inline functions which
test to see whether a contiguous range of blocks is
available.
Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
use ext2fs_badblocks_* instead of badblocks_*
* bb_compat.c: New file which translates between old badblocks_*()
names to ext2fs_badblocks_*()
* unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
link.c (since e2fsck doesn't use ext2fs_unlink()).
* rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
bitmap resizing routine moved from bitmaps.c, since e2fsck
doesn't need to use this function.
* lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
since e2fsck only needs ext2fs_lookup.
Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
already set; this is needed so that programs like dump
which use the inode scan functions will deal with
filesystems that have bad blocks in the inode table.
Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
Moved to ext2fsP.h, since it doesn't need to be part of
the public interface.
* dir_iterate.c: Move ext2_dir_iterate out of namei.c.
Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* dblist.c (ext2fs_get_num_dirs): New file, which implements a
directory block list abstraction. (Code moved from
e2fsck).
* ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
to inode.c (since no one else should be peeking inside it!)
* valid_blk.c (ext2_inode_has_valid_blocks): New function.
* openfs.c (ext2fs_open): Check the feature set in the ext2
superblock, and refuse to open filesystems if they contain
incompatible features. (Can be overriden with the
EXT2_FLAG_FORCE
Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* block.c (ext2fs_block_iterate2): Added new function
ext2fs_block_iterate2 which changes the function
signature of the callback function to include the
referencing block and offset.
* inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
ext2fs_inode_scan_goto_blockgroup which allows an
application to jump to a particular block group while
doing an inode scan.
Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* dirblock.c: Include string.h, since we use memcpy().
Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
a long not an int; this doesn't matter on i386 machines,
but it does on Alpha's.
Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
table pointer is NULL, then return an error indicating
that the inode table is missing.
(get_next_blockgroup, get_next_blocks,
ext2fs_get_next_inode): Don't treat a missing inode table
as permanent error. Return MISSING_INODE_TABLE, but as an
advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
* rw_bitmaps.c (ext2fs_write_block_bitmap,
ext2fs_write_inode_bitmap): If the inode or block bitmap
block is zero, then don't write out the inode or block
bitmap. The idea here is to avoid stomping on the
superblock.
(read_bitmaps): If the inode or block bitmap block is
zero, then fill in that portion of the inode or block
bitmap with all zeros.
* inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
blocks in inode table when the inode table size is
non-standard (and can therefore span blocks).
Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* alloc.c (ext2fs_new_block): Fix fencepost error in
ext2fs_new_block; make sure we don't try to allocate the
first block beyond the end of the filesystem.
Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (check_for_inode_bad_blocks): New function called by
get_next_blocks() to avoid reading in bad blocks marked in
fs->badblocks. Inodes located in bad blocks are returned
by ext2fs_get_next_inode() returns the error code
EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
* alloc_tables.c (ext2fs_allocate_tables): New function which
performs the part of mke2fs's job of allocating the
filesystem tables.
* test_io.c (test_close): IO manager which is used for testing
purposes.
Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (ext2fs_get_next_inode): Separate out the function of
setting up for a new block group to get_next_blockgroup().
Separate out the function of reading in blocks of the
inode table to get_next_blocks().
* ext2fs.h: Add the badblocks list to the ext2_filsys entry
* badblocks.c (badblocks_list_add, badblocks_list_test): Add
blocks to the badblock list in sorted order. This allows
badblocks_list_test to be coded using a binary search for
speed.
Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs version 1.06
Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
consistency's sake.
* closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
set, then only write out the master superblock.
Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* block.c (ext2fs_block_iterate): Fixed bug which caused
block_iterate to fail to handle HURD created filesystems;
it tested the inode translator field before the inode was
loaded.
Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* initialize.c (ext2fs_initialize): Make sure the description for
the inode bitmap is set correctly.
* bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs version 1.05
Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* initialize.c: Override the kernel's idea of default
checkinterval from 0 (never) to 180 days.
Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* namei.c (ext2fs_namei_follow): New function which follows
symbolic link (if any) at the target.
Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
for shortcut function fs->read_inode() and fs->write_inode().
Added inode_cache to reduce CPU time spent in doing
byte swapping.
* swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
superblock.
* namei.c (ext2fs_follow_link): New function.
(ext2fs_namei): Extended to have support for chasing
symbolic links. ext2fs_namei() still returns an inode
which is a symbolic link. Symbolic links are only chased
while resolving the containing directory. To chase
symbolic links of the final result, use
ext2fs_follow_link().
Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
* bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* initialize.c (ext2fs_initialize): On systems where the byte
order is not i386 compatible, set the swap_byte flag.
* inode.c (inocpy_with_swap): Check to see if inode contains a
fast symlink before swapping the inode block fields. This
required adding a new argument to inocpy_with_swap to
determine whether the mode field is in host order or not.
Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
the sparc, if EXT2_STD_BITOPS set, use the standard
i386-compatible bitmask operations, instead on the
non-standard native bitmask operators.
Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* block.c (ext2fs_block_iterate): Cause block iterator to return
the HURD translator block (along with everything else).
If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
iterator, then don't return any meta data blocks
(including the HURD translator).
Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* gen_uuid.c: New file, which generates DCE-compatible UUIDs.
* uuid.c: New file, containing UUID utility functions.
Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2fs.h: Add a definition of the "real" ext2 superblock.
Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

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

Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
to avoid conflicts with with kernel include files. Also
rename ADDR and CONST_ADDR to EXT2FS_ADDR and
EXT2FS_CONST_ADDR.
Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
* ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
* swapfs.c (ext2fs_swap_super): Put an #ifdef check around

Move these functions to freefs.c.
* closefs.c (ext2fs_flush): If swapping blocks, clear the group
descriptors shadow memory to keep purify quiet. (This
also has the nice benefit that the unused portion of the
shadow descriptors are zeroed out.)
* dirblock.c (ext2fs_write_dir_block): We need to use
dirent->rec_len *before* it's byteswapped to find the
location of the next directory structure!
* alloc.c (ext2fs_new_inode): Fix bug which could potentially
cause ext2fs_new_inode to loop infinitely if we're trying

block_iterate_tind): Byte swap the block addresses if
EXT2_SWAP_BYTES is set (and swap them back before writing
them out.)
* inode.c (inocpy_with_swap): New function.
(ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
* closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
the superblock and group descriptors before writing it out.
* openfs.c (ext2fs_open): If the magic number is byte-swapped,
then set the EXT2_SWAP_BYTES and byte-swap the superblock
and group descriptors.
* swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
to desp ext2 filesystem structures.
* bitops.c (set_bit, clear_bit, test_bit): Use modifications
supplied by Pete A. Zaitcev so that the C language
versions of these functions are more portable. They will
now work on both little and big endian systems, and the
assumption that 32-bit integers are used is gone.
* bitops.h (ext2_swab16, ext2_swab32): Added new functions for
doing byte swapping.
* ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
byte swapping should take place.

Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
* block.c (block_iterate_ind, block_iterate_dind,
block_iterate_tind): Don't recompute block_nr each loop;
just increment it! Factor check of BLOCK_FLAG_APPEND out
of the loop. Factor mask of BLOCK_CHANGED into changed
variable out of the loop. (block_iterate_ind, in
particular, gets called a lot, so every little
optimization helps.)
Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
* block.c (block_iterate_ind, block_iterate_dind,
block_iterate_tind): Precompute limit of loop to speed up

ext2fs_get_inode_bitmap_end): Add new accessor functions
which return the start and end points of the bitmaps.
Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
* llseek.c (ext2_llseek): If the offset is small enough, use lseek

and lseek is not supported should be EINVAL, not -EINVAL.
Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
* Makefile.in: Added support for ELF shared libraries.
Fixed typos in the compilation rules.
(distclean): Added Makefile.

C library.
(ext2_llseek): Changed to call llseek().
Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

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

support separate compilation directories.
Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
* initialize.c (ext2fs_initialize): Don't allow more than one
bitmaps's worth of inodes in a group.
Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
* llseek.c (ext2_llseek): Added error checking to the llseek()
compat code to protect against overflow. This only
applies to 1.0 and early 1.1 kernels, which don't support
the llseek() system call.
Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
* unix_io.c (unix_open): Initialize the read_error and write_error
io_channel pointers to be null.
* bb_inode.c (clear_bad_block_proc): If an illegal block number is
found, clear it but don't try to update the filesystem
accounting information, since that's hopeless anyway.
* block.c (bloblock_iterate_ind, bloblock_iterate_dind,
bloblock_iterate_tind): Check to see if the indirect blocks are
valid before trying to read them.
* ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
EXT2_ET_BAD_TIND_BLOCK): Add new error codes.

ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
illegal block or inode number is passed in, return instead
of trying to test, set, or clear the bit.
Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
* Makefile: Added a dummy install target in case shared libraries
are not built.
Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
* bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
the real last block of the bitmap should be calculated.

ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
ext2fs_free_block_bitmap): Add magic number checking for
the inode and block bitmaps.
* bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
magic number for a block bitmap instead of an inode bitmap.
* inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
magic number checking for the inode_scan structure.
* badblocks.c (badblocks_list_free, badblocks_list_add,
badblocks_list_test, badblocks_list_iterate_begin,
badblocks_list_iterate, badblocks_list_iterate_end): Add
magic number checking for the badblocks_list and
badblocks_iterate structures.
* ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
* unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
unix_write_blk, unix_flush): Add magic number checking
both for io_channel structure and unix_private_data
structure.
* openfs.c (ext2fs_open): Add check for io_manager structure's
magic number.
* rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
ext2fs_read_bitmaps, ext2fs_write_bitmaps):
* read_bb.c (ext2fs_read_bb_inode):
* read_bb_file.c (ext2fs_read_bb_FILE):
* newdir.c (ext2fs_new_dir_block):
* namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
* link.c (ext2fs_link, ext2fs_unlink):
* inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
ext2fs_write_inode, ext2fs_get_blocks,
ext2fs_check_directory):
* get_pathname.c (ext2fs_get_pathname):
* expanddir.c (ext2fs_expand_dir):
* block.c (ext2fs_block_iterate):
* bitmaps.c (ext2fs_allocate_inode_bitmap,
ext2fs_allocate_block_bitmap):
* bb_inode.c (ext2fs_update_bb_inode):
* alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
* check_desc.c (ext2fs_check_desc):
* closefs.c (ext2fs_close, ext2fs_flush):
* freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
* Makefile:
* ext2fs.h:
* openfs.c:
* check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
openfs.c into its own file.
* ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
structure magic numbers.
* closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
the EXT2_VALID_FS flag in the backup superblock blocks, so that if
someone uses the -b option to specify the use of the backup
superblock --- this usually means that the main superblock is
toast. :-)
* ext2fs.h:
* ext2_err.et (EXT2_ET_REV_TOO_HIGH):
* openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
revision level to the superblock.

* ext2fs.h:
* bitmaps.c:
* bitops.c
* bitops.h:
* openfs.c:
* initialize.c: Completely revamped the inode and block bitmap
structures, so that they can be better chance of being extensible
in a shared library. They are now their own type, instead of
being a char *. Also, the function signatures of
ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
changed to eliminate the ext2_filsys argument, since it is no
longer necessary.
Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
* unix_io.c (unix_read_blk and unix_write_blk): use the llseek
system call if available.
* llseek.c: new file. This is the stub calling the llseek system
call which allows supports for 2GB+ file systems.
* initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
the creator operating system.
Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
* initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
the group descriptor statistics in addition to everything else.
This relieves mke2fs of the responsibility of doing it.
* bitops.c, bitops.h: Add assembly inline functions for the 68000.
Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
not the generic C function equivalents should be included or not.
* openfs.c (ext2fs_open): If a superblock is specified, then use
the backup group descriptors that go along with this superblock,
instead of using the primary group descriptors. This allows
e2fsck to recover filesystems where the primary group descriptors
have been trashed.
