blob: f8dff7fff2f7ab2379c3fea4b64dd2ca20cc0acb [file] [log] [blame]
2001-06-13 Theodore Tso <tytso@valinux.com>
* ismounted.c (check_mntent_file): Work around GNU hurd brain
damage. Addresses Debian bug #100304.
* Makefile.in: Limit some .o files from being included into the
library if --disable-debugfs, --disable-swapfs,
--disable-imager, or --disable-resizer are used.
2001-06-12 Theodore Tso <tytso@valinux.com>
* inode.c, tst_iscan.c: Stop using the compatibility badblocks
function, and use the ext2fs_badblocks_* functions
instead.
2001-06-11 Theodore Tso <tytso@valinux.com>
* Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
ext2fs_mark_generic_bitmap and
ext2fs_unmark_generic_bitmap to gen_bitmap.c as normal
functions. (This saves space and doesn't significantly
change the speed of e2fsck on a P-III.)
* ext2fs.h, bitops.h, block.c, bmap.c, closefs.c, dirblock.c,
inode.c, native.c, openfs.c, rw_bitmaps.c, swapfs.c: Only
include the byte-swapping logic if ENABLE_SWAPFS is turned
on or if we're on a big-endian machine.
* initialize.c (ext2fs_initialize):Use WORDS_BIGENDIAN directly to
set EXT2_FLAG_SWAP_BYTES, instead of using
ext2fs_native_flag.
* native.c (ext2fs_native_flag): Use WORDS_BIGENDIAN provided by
autoconf to determine whether or not return
EXT2_FLAG_SWAP_BYTES.
2001-06-10 Theodore Tso <tytso@valinux.com>
* Makefile.in: Remove the dependence on the libe2p library.
* mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags
with direct usage of the ioctl/fchflags so that we don't
have to depend on the libe2p library.
2001-06-08 Theodore Tso <tytso@valinux.com>
* ext2_types.h.in: Use unsigned ints in favor of unsigned longs
when trying to find a 32-bit wide type.
* icount.c (insert_icount_el): Fix the code used to estimate the
size of the new icount array to be more intelligent, to
avoid reallocating the array too many times. Thanks to
Enrique Perez-Terron for pointing this out.
2001-06-02 Theodore Tso <tytso@valinux.com>
* valid_blk.c (ext2fs_inode_has_valid_blocks): Only check i_blocks
for a symlink to determine whether it is a fast symlink.
2001-06-01 Theodore Tso <tytso@valinux.com>
* Makefile.in, dosio.c, ext2_fs.h, ext2_types.h.in, ext2fs.h:
Move include/asm/types.h.in to lib/ext2fs/ext2_types.h.in.
2001-05-25 Theodore Tso <tytso@valinux.com>
* Release of E2fsprogs 1.20
2001-05-25 Theodore Tso <tytso@valinux.com>
* ismounted.c: More cleanups for ismounted.c, some from Andreas,
some to clean up Andreas's patches. Use strncpy instead
of strcpy to save the root's mountpoint. Clean up #ifdef
structure. Remove uneeded variable in testing/debug driver.
2001-05-24 Andreas Dilger <adilger@turbolinux.com>
* ismounted.c: Add check for root device which doesn't depend on
/etc/fstab or /proc/mounts to be correct. Don't call
endmntent() before we are done with mnt struct.
2001-05-23 Theodore Tso <tytso@valinux.com>
* ext2_err.et.in (EXT2_ET_JOURNAL_UNSUPP_VERSION): Added new error
code.
2001-05-21 Theodore Tso <tytso@valinux.com>
* ext2_fs.h: Change assignment of EXT2_FEATURE_COMPAT_DIR_INDEX to
make room for pre-existing usage of
EXT2_FEATURE_COMPAT_EXT_ATTR. Add flag EXT2_INDEX_FL with
the same codepoint as EXT2_BTREE_FL.
2001-05-20 Theodore Tso <tytso@valinux.com>
* ext2fs.h: #include <> instead of "" for ext2fs and et header
files, since they will be installed in /usr/include
2001-05-14 Theodore Tso <tytso@valinux.com>
* alloc.c, alloc_tables.c, badblocks.c, bb_compat.c, bb_inode.c,
bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,
check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c,
dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c,
expanddir.c, ext2_fs.h, fileio.c, finddev.c, flushb.c,
freefs.c, get_pathname.c, getsize.c, icount.c, imager.c,
initialize.c, inline.c, inode.c, irel_ma.c, ismounted.c,
link.c, lookup.c, mkdir.c, mkjournal.c, namei.c, native.c,
newdir.c, nt_io.c, openfs.c, read_bb.c, read_bb_file.c,
rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c,
tst_badblocks.c, tst_byteswap.c, tst_getsize.c,
tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c,
write_bb_file.c, ext2_fs.h: Moved file from include/linux.
Adjust all files in this directroy to include this file.
* mkjournal.c (ext2fs_create_journal_superblock): Remove redundant
code.
2001-05-05 Theodore Tso <tytso@valinux.com>
* fileio.c (ext2fs_file_read): Factored out common code and
cleaned up function. Fixed a bug where if there was an
error reading from the disk, the number of bytes read
wasn't reliably set. (Fixes Debian bug #79163)
(ext2fs_file_write): Factored out common code and made
function more efficient; if writing a full block, don't
bother to do a read-modify-write cycle.
2001-05-04 Theodore Tso <tytso@valinux.com>
* dirblock.c (ext2fs_read_dir_block): Check for an directory
record length which isn't a multiple four, and treat that
as an invalid. Scan the directory and return an error
(EXT2_ET_DIR_CORRUPTED) if the directory records are
corrupted.
(ext2fs_write_dir_block): If while byte-swapping the
directory block, if there's an error, abort and return
EXT2_ET_DIR_CORRUPTED.
2001-05-02 Theodore Tso <tytso@valinux.com>
* ext2fs.h (EXT2_FLAG_IMAGE_FILE): Add new flag, and add
image_header field in the ext2_filsys structure
* block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind):
* inode.c (ext2fs_read_inode):
* rw_bitmaps.c (read_bitmaps):
* openfs.c (ext2fs_open): Add support for EXT2_FLAG_IMAGE_FILE
* imager.c (ext2fs_image_bitmap_read): Fix bug in imager to make
sure the full bitmap is saved.
2001-05-01 Theodore Tso <tytso@valinux.com>
* e2image.h (struct ext2_image_hdr): Add space for the device name
in the image header.
* dir_iterate.c (ext2fs_process_dir_block): Add a double-check to
make sure the rec_len is a multiple of 4, to prevent
bus-errors on architectures which care about mis-aligned
pointer references.
2001-04-25 Theodore Tso <tytso@valinux.com>
* getsize.c (ext2fs_get_device_size): Use an unsigned long to
query the device sizes using the BLKGETSIZE ioctl.
2001-04-16 Theodore Tso <tytso@valinux.com>
* ismounted.c (check_mntent): Check /proc/mounts on Linux systems
before checking /etc/mtab. The EXT2_MF_READONLY flag is
now set from the /etc/mtab options field for all
filesystems, not just the root filesystem. Add debugging
code to make it easier to test ext2fs_check_if_mounted().
* mkjournal.c (ext2fs_create_journal_superblock): Add safety
check; return an error if there's an attempt to create a
journal less than 1024 filesystem blocks.
* ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
2001-02-20 Theodore Tso <tytso@valinux.com>
* bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly
inline functions.
* tst_byteswap.c: New function to test the byteswap functions.
Add to regression test suite.
2001-02-08 Theodore Tso <tytso@valinux.com>
* e2image.h (struct ext2_image_hdr): Fix type for fs_hostname
2001-02-07 Theodore Tso <tytso@valinux.com>
* mkjournal.c (ext2fs_create_journal_superblock): Fix the setting
of s_first for external devices to always be 1, since
jsb->s_first is always relative to the start of the
journal superblock. Use htonl(1) when setting s_nr_users.
2001-01-17 Theodore Ts'o <tytso@valinux.com>
* mkjournal.c (ext2fs_add_journal_device): Fix bug where the
device number of the filesystem (instead of the journal)
was being dropped into s_journal_dev.
2001-01-15 Theodore Ts'o <tytso@valinux.com>
* initialize.c (ext2fs_initialize): Add support for initializing
the ext2 superblock for external journal devices. This
basically means we don't bother to allocate any block
group descriptors.
* openfs.c (ext2fs_open): Only open external journal devices if
the new flag EXT2_FLAG_JOURNAL_DEV_OK is passed to
ext2fs_open. When opening such devices, don't try to read
the block group descriptors, since they're not there.
* ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
* mkjournal.c: Export a new function,
ext2fs_create_journal_superblock(), which allocates and
returns a buffer containing a journal superblock. This is
needed by mke2fs to create an external journal. Rewrote
ext2fs_add_journal_device() so that it no longer creates
the external journal, but rather adds a filesystem to an
existing external journal. It handles all of the UUID
manipulation.
* ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported
by the library. Define the EXT2_FLAG_JOURNAL_DEV_OK.
Changed function prototype for ext2fs_add_journal_device().
2001-01-14 Theodore Ts'o <tytso@valinux.com>
* closefs.c (ext2fs_flush): Don't write out anything beyond the
primary superblock if EXT2_INCOMPAT_JOURNAL_DEV is
listed.
2001-01-12 Theodore Ts'o <tytso@valinux.com>
* imager.c: Fix gcc -Wall complaints and a series of bugs where
retval wasn't set correctly. (Thanks to Andreas Dilger
for pointing this out.)
2001-01-11 <tytso@snap.thunk.org>
* flushb.c (ext2fs_sync_device): New function which centralizes
all of the places which might try to use the BLKFLSBUF
or FDFLUSH ioctls (and usually failing to define them
since the system header files don't usually do this for
us, and we're trying to avoid usage of kernel include
files now).
2001-01-10 <tytso@snap.thunk.org>
* alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c,
bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c,
dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c,
finddev.c, get_pathname.c, icount.c, inode.c, irel.h,
irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c,
mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c,
tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to
ext2_ino_t, to protect applications that attempt to
compile -D_FILE_OFFSET_BITS=64, since this inexplicably
changes ino_t(!?). So we use ext2_ino_t to avoid an
unexpected ABI change.
2001-01-05 <tytso@snap.thunk.org>
* dirblock.c (ext2fs_read_dir_block): Fix a potential case where
we may overrun allocated memory in case of a corrupted
filesystem (or an e2fsck test case :-) when byte-swapping
the directory block.
* ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
* mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
complaints including a missing return 0 at the end of
ext2fs_add_journal_device.
2001-01-03 <tytso@snap.thunk.org>
* Makefile.in: Link in libe2p when creating libext2fs as a shared
library, since mkjournal.c now references fsetflags().
* mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas
Dilger's changes (with fixups) to allow on-line creation
of a journal file.
* ext2fs.h, closefs.c (ext2fs_flush): Add new flag,
EXT2_FLAG_SUPER_ONLY, which the close routines to only
update the superblock, and not the group descriptors.
2000-12-30 Andreas Dilger <adilger@turbolinux.com>
* ismounted.c: add ext2fs_check_mount_point() function, which will
optionally return the mount point of a device if mounted
2000-12-14 Andreas Dilger <adilger@turbolinux.com>
* mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
ext2fs_add_journal_inode()
2001-01-01 <tytso@snap.thunk.org>
* ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
source (but not binary) compatibility of some users of the
ext2 library. They should just simply do a global search
and replace of struct ext2fs_sb with struct
ext2_super_block, and use their own private copy of
ext2_fs.h if they aren't already.
* closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
Replace use of ext2fs_sb with ext2_super_block.
2000-12-31 <tytso@snap.thunk.org>
* ext2fs.h: Cleaned up header file by removing definitions of
feature flags that might not have been defined in older
ext2 header files. Now that we're using our own
include/linux/ext2fs.h header file, this can never happen.
* jfs_dat.h: Removed old header file which is no longer needed.
2000-12-13 Theodore Ts'o <tytso@valinux.com>
* closefs.c (ext2fs_update_dynamic_rev): New function suggested
by Andreas Dilger to update the filesystem revision to
EXT2_DYNAMIC_REV.
* swapfs.c (ext2fs_swap_super): Add byte swapping for the journal
fields.
2000-12-09 <tytso@snap.thunk.org>
* ext2fs.h, mkjournal.c (ext2fs_add_journal_inode,
ext2fs_add_journal_device): Add a new argument to the APIs
of these function, which is a flags word. This is used to
allow the creation of a V1 superblock for those folks who
are using ext3 0.3b in production. Note, the user-land
interface for getting at this flag won't be documented, as
the V1 superblock is deprecated.
* mkjournal.c (init_journal_superblock): Sync Stephen's changes
which creates a V2 superblock instead of a V1 superblock.
2000-11-21 <tytso@snap.thunk.org>
* test_io.c (test_write_blk, test_write_byte): Fix typos pointed
out by Andreas Dilger.
2000-11-05 <tytso@snap.thunk.org>
* imager.c (ext2fs_image_{inode,super,bitmap}_{read,write},
ext2_fs.h, Makefile.in: New file that has routines that
save ext2fs metadata to a file.
* ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned.
* e2image.h: New file which defines the file format for the ext2
image file. (Saved copy of ext2 metadata to a file as a
saving throw against worst-case damage.)
2000-11-01 <tytso@snap.thunk.org>
* inode.c (ext2fs_flush_icache): Add new function
ext2fs_flush_icache() which flushes the internal inode
cache. Applications which modify the inode table blocks
directly must call this function.
2000-10-26 <tytso@snap.thunk.org>
* mkjournal.c: Add #include of netinet/in.h, since Solaris
requires it for ntohl().
* ext2_io.h (io_channel_write_byte): Add new interface to allow
callers to write specific byte ranges. This is an
optional interface, which not all IO channels may
implement.
* unix_io.c (unix_write_byte):
* test_io.c (test_write_byte): Add implementation of the
write_byte function.
* closefs.c (write_primary_superblock, ext2fs_flush): Add a new
function which writes the primary superblock. If the IO
channel supports writing raw bytes directly, only fields
which were modified are written to the disk. This makes
it safe(r) to use utilities like tune2fs on a mounted
filesystem.
* freefs.c (ext2fs_free): Free the original superblock if it is
available.
* openfs.c (ext2fs_open): Store a copy of the original superblock
when opening it.
* ext2fs.h: Add a field to store the original superblock in the
ext2 context structure.
2000-10-24 <tytso@snap.thunk.org>
* llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
don't need to use llseek).
2000-10-24 <tytso@valinux.com>
* Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
creating an ext3 journal on a filesystem.
2000-08-21 <tytso@valinux.com>
* ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.
2000-08-22 <tytso@valinux.com>
* unix_io.c: Make massive changes to support a multiple block
writethrough cacheing.
* ext2_io.h: Added flags field to the io_channel structure.
2000-08-19 <tytso@valinux.com>
* finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
provides the function ext2fs_find_block_device(). This
function returns the pathname to a block device, given its
device number.
2000-07-13 <tytso@valinux.com>
* Release of E2fsprogs 1.19
2000-07-07 Theodore Ts'o <tytso@valinux.com>
* ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
list of filesystem flags supported by the library.
2000-07-04 Theodore Ts'o <tytso@valinux.com>
* ext2fs.h: Update to include latest journalling additions to the
superblock.
* dll/jump.funcs: Add new jumptable entries for
ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
ext2fs_badblocks_equal.
* tst_badblocks.c: Update test program to test
ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
* write_bb_file.c (ext2fs_write_bb_FILE): New function which
writes out bad blocks list to a file.
* read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
changes the callback function to take two additional
arguments; a private blind pointer supplied by the caller,
and pointer to a char * containing a pointer to the
invalid string.
* badblocks.c (ext2fs_badblocks_equal): Add new function which
returns true if two badblocks list are equal.
* Makefile.in: Remove explicit link of -lc in the shared library.
(It shouldn't be necessary, and is harmful in some cases).
2000-06-10 Theodore Ts'o <tytso@valinux.com>
* getsize.c (main): Add debugging code under #ifdef DEBUG
2000-05-27 Theodore Ts'o <tytso@valinux.com>
* mkdir.c (ext2fs_mkdir): Read the parent directory's inode
earlier, so that if there's an error reading it, we can
more cleanly back out of the operation.
2000-05-25 <tytso@snap.thunk.org>
* getsize.c (ext2fs_get_device_size): Use open64() instead of
open() if it exists. Under linux, manually define the
ioctl for BLKGETSIZE if it isn't already defined and it's
safe to do so.
* unix_io.c (unix_open): Use open64() instead of open() if it
exists.
* llseek.c: Simplify header includes of unistd.h. If lseek64 is
available (and prototypes are defined) use it in
preference to llseek.
* Makefile: Add hack dependency rule so that parallel makes work
correctly.
2000-05-18 Theodore Ts'o <tytso@valinux.com>
* ext2fs.h: Add appropriate ifdef's to support C++ compilation.
2000-04-03 Theodore Ts'o <tytso@valinux.com>
* block.c: Readibility tweak in conditionals involving
ctx->fs->flags.
* ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
how to define __s64 and __u64. Turn off "compression is
experimental" warning if the cpp macro
I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
2000-02-11 <tytso@snap.thunk.org>
* ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
Conditionally include Compression as a supported type if
ENABLE_COMPRESSION (via --enable-compression) is turned on.
* swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
2000-02-08 <tytso@snap.thunk.org>
* bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
Change to return the previous state of the bit that is
being marked or unmarked. For speed optimization.
2000-02-02 Theodore Ts'o <tytso@valinux.com>
* getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
* swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
needed any more; we know it will always be i_generation.
Add support for swapping the high bits of the uid and gid.
1999-11-19 <tytso@valinux.com>
* mkdir.c (ext2fs_mkdir): Only update the parent's inode link
counts if the link was successful. Patch suggested by
jeremy@goop.org.
* Makefile.in (distclean): Remove TAGS and Makefile.in.old from
the source directory.
1999-11-10 <tytso@valinux.com>
* Release of E2fsprogs 1.18
1999-11-08 <tytso@valinux.com>
* Makefile.in (tst_badblocks): Add freefs.o to the object list,
since ext2fs_badblocks_list_free was moved to freefs.c.
* tst_badblocks.c: Use the newer badblocks API names. Add
duplicate blocks to the test inputs to test dealing with
adding blocks which are already in the badblocks list.
* badblocks.c (ext2fs_badblocks_list_add): If appending to the end
of the list, use a shortcut O(1) operations instead of an
O(n) operation. (Idea suggested by David Beattie.)
* freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
of badblocks_list_free(), to save a procedure call.
1999-10-26 <tytso@valinux.com>
* Release of E2fsprogs 1.17
1999-10-26 <tytso@valinux.com>
* ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
seem to handle ~0UL the same way as they used to.
1999-10-25 <tytso@valinux.com>
* nt_io.c (_OpenNtName): Open the device using
FILE_SYNCHRONOUS_IO_NONALERT instead of
FILE_SYNCHRONOUS_IO_ALERT
(nt_open): At the end of the device open routine, unlock
the drive but do not dismount it.
* initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
detect the Hurd OS.
1999-10-22 <tytso@valinux.com>
* Release of E2fsprogs 1.16
1999-10-22 <tytso@valinux.com>
* mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
* link.c (ext2fs_link): This call now uses the low three bits of
the flags parameter to pass the directory filetype
information; it will set the directory entry FILETYPE
information if the filesystem supports it.
* newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
option is set, then create the '.' and '..' entries with
the filetype set to EXT2_FT_DIR.
1999-09-24 <tytso@valinux.com>
* nt_io.c: New file which supports I/O under Windows NT.
1999-09-07 <tytso@valinux.com>
* ext2fs.h: Add new fields for journalling and define new
feature bits used by newer filesystems: IMAGIC_INODES,
HAS_JOURNAL, RECOVER.
* expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
we update the inode block count and size files so that the
block count field is updated correctly when we create an
indirect block.
1999-07-18 Theodore Ts'o <tytso@valinux.com>
* Release of E2fsprogs 1.15
1999-06-23 <tytso@valinux.com>
* swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
kernels that use i_generation instead of i_version. Patch
supplied by Jon Bright <sircus@sircus.demon.co.uk>.
1999-06-21 <tytso@valinux.com>
* dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
directory entry before calling the callback function.
This should prevent some core dumps of insufficiently
paranoid callback functions.
1999-05-29 <tytso@rsts-11.mit.edu>
* ext2fs.h: Add feature definition for AFS IMAGIC inodes.
* fileio.c (ext2fs_file_open): Remove obsolete comment stating
that we don't handle writing yet (we do). Fixed bug where
we weren't allocating a big enough buffer for ext2_bmap.
1999-05-03 <tytso@rsts-11.mit.edu>
* openfs.c (ext2fs_open): Check to make sure that the number of
blocks per group is not zero --- if so, it must be a bad
superblock!
1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs 1.14
1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
the inode number is zero; if it's zero, return
EXT2_ET_BAD_INODE_NUM.
1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
* initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead

header files.
Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
* llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
non-Linux case to use EINVAL by default, unless it isn't

enough inodes so that we can make a valid filesystem.
1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
* rw_bitmaps.c: Fixed signed/unsigned warnings.
* fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
function declaration.
* dblist.c (make_dblist): Add safety check in case the dblist
pointer passed in is null (in which case, assign it to
fs->dblist). Fixed some signed/unsigned warnings.
* bmap.c: Make addr_per_block be of type blk_t to avoid
signed/unsigned warnings.
* namei.c (ext2fs_follow_link): Remove uneeded extern from the
function declaration.
* get_pathname.c (get_pathname_proc): Use return value from
ext2fs_get_mem, instead of checking if &gp->name is
NULL.

* dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
from the function declaration.
* block.c (ext2fs_block_iterate2): If the read_inode call fails,
return the error directly instead of jumping to the
cleanup routine, since we don't need to do any cleanup.
* alloc_table.c (ext2fs_allocate_group_table): Make this
function take a dgrp_t for its group argument.
* ext2fs.h: Make dgrp_t an __u32 type, and make

* Release of E2fsprogs 1.12
1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
* closefs.c (ext2fs_flush): Update the s_block_group_nr field as
appropriate for all of the block group copies, so that
it's clear where the beginning of the filesystem is on the
disk. (For when the partition table gets scrod.)
* ext2fs.h: Change the name of the feature from
EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (get_next_blockgroup): Fix bug where if
get_next_blockgroup() is called early because of a missing
inode table in a block group, the current_inode counter
wasn't incremented correctly.
1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
* read_bb.c (ext2fs_read_bb_inode): Make function more robust
against a completely trashed bad block inode.
1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
* alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
the stride length hits a bad value, we retry the block
allocation starting at the beginning of the block group.
* ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
e2_blkcnt_t to avoid collision with LFS API.
1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
* initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
way that avoids overflows on disk sizes greater than 4GB.

declaration.
1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
inline functions.
* ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
evade a potential problem with glibc's header files trying
to spike out linux/types.h.
* ext2fs.h (ext2fs_resize_mem): Change the function prototype to
include the old size of the memory, which is needed for
some braindamaged memory allocation systems that don't
support realloc().

convention. Fix uninstall rules to take $(DESTDIR) into
account.
1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
with 32 bit longs, then we need to manually define __s64
and __u64, since the current kernel header files don't
define these if __STRICT_ANSI__ is defined. This is a
problem if we are compiling with full GCC warnings, since
we do need 64 bit support.
* Makefile.in (OBJS): Remove bmove.o from files to be built,
since we're not using ext2fs_move_blocks() and there
is some question as to its usefulness in its current
form.
* bmap.c (block_bmap): Remove unused function.
* bmove.c (process_block): Fix -Wall warning.
1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
* block.c (ext2fs_block_iterate3): Make the ref_offset field
contain the offset into the inode.i_blocks array when
ref_block is zero. Since we haven't done a formal
release of e2fsprogs since block_iterate2 was first
introduced, I removed block_iterate2, and renamed
block_iterate3 to be block_iterate2.
* bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
use of block_iterate and block_iterate2 to
block_iterate2 with the new prototype for the
interator function. (using blkcnt_t forr blockcount)
1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
s_prealloc_blocks, s_prealloc_dir_blocks). Added
conditional defines of new features COMPAT_DIR_PREALLOC,
RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
the library to declare that we support COMPAT_DIR_PREALLOC,
INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
* fileio.c: Rename function ext2fs_file_llseek to be
ext2fs_file_lseek, which is more accurate.
* block.c: Add new function ext2fs_block_iterate3 which calls
the iterator function with the blockcount argument of
type blkcnt_t. This version of the function is
allowed to handle large files; the other fucntions are
not.
* ext2fs.h: Add new type blkcnt_t
* ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
* block.c (ext2fs_block_iterate2): Fix bug where the block count
field wasn't getting correctly incremented for sparse
files when the indirect or doubly-indirect block
specified in the inode was zero.
Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unlink.c (unlink_proc):
* lookup.c (lookup_proc):
* link.c (link_proc):

from dirent->name_len, so it can be used for other
purposes.
* ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
and indicate that we have support for this incompatible
option.
Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
number of directories when the block group information is
unreliable.
1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
* inode.c (ext2fs_get_next_inode): Always do the check to see if the
inode table is missing so that we catch the case where the
first block group is missing.
* getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
needed.
Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* ext2_io.h, ext2fs.h: Protect against being included multiple times.
* bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
* test_io.c (test_flush): Add a debugging printf when the flush
method is called.
* rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
read in, return right away.
Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* bitops.h: Don't try to do i386 inline asm functions if the
compiler isn't GCC.
* ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
instead of linux/types.h, and e2_bitops.h instead of
ext2fs/bitops.h.
* icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
necessary.
Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* inode.c (ext2fs_open_inode_scan): Initialize the group variables
so that we don't need to call get_next_blockgroup() the
first time around. Saves a bit of time, and prevents us
from needing to assign -1 to current_group (which is an
unsigned value).
* icount.c (insert_icount_el): Cast the estimated number of inodes
from a float to an ino_t.
* alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
defined, then assume all of the
ext2-specific header files are in a flat directory.
* block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
all assignments from void * to be compatible with C++.
Tue Jan 6 11:28:15 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
make sure the contents of the disk are flushed to disk.
Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
avoid C++ namespace clash.

* dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
paranoid about validating the directory counts from the
block group information.
* all files: Don't include stdlib.h anymore; include it in
ext2_fs.h, since that file requires stdlib.h
Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* expanddir.c (ext2fs_expand_dir): Check to make sure the block
bitmap is loaded, and return an error if it is not.
(expand_dir_proc): Only use ext2fs_write_dir_block when
writing a directory block, not when writing out a fresh
indirect block.
Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Makefile.in, tst_getsize.c: Added new file which is used to test
the ext2fs_get_device_size function.

* Rename new error codes to _ET_ in them for consistency.
Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* [all files, basically]: Added definition of ext2fs_get_mem,
ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
changed all library routines to use these wrapper functions.
* dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
instead of the system error messages.

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

current inode number wasn't being set by the
goto_blockgroup function.
Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* bmove.c (ext2fs_move_blocks): New function which takes a bitmap
of blocks which need to be moved, and moves those blocks
to another location in the filesystem.
* rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
bitmap, make sure all of the new parts of the bitmap are
zero.
Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

wasn't being returned to the caller.
* alloc_tables.c (ext2fs_allocate_group_table): Add new function

* alloc_tables.c (ext2fs_allocate_tables): Make sure that we
allocate the inode and block bitmaps inside block group at
all times.
Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
filesystem has no free blocks, ext2fs_new_block would loop
forever.
* dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
* freefs.c (ext2fs_free_inode_cache): Decrement refcount and only

* ext2fs.h: Added pointer to the inode_cache structure.
* block.c (block_iterate_ind, block_iterate_dind,
block_iterate_tind): If there are holes in the indirect,
doubly indirect, or triply indirect blocks, increment the

block of a dblist entry, given the directory inode and
blockcnt.
Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
inode bitmaps at staggered locations across the block
groups, to avoid concentrating the bitmaps on a small
number of disks when using striped RAID arrays.
* initialize.c (ext2fs_initialize): By default, choose the maximum
possible number of blocks per group (based on the size of
the bitmaps in the blocksize).
Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* initialize.c (ext2fs_initialize): Add support for
EXT2_COMPAT_SPARSE_SUPER feature.

whether or a particular block group should have a
superblock and block group descriptor. Used for the
EXT2_COMPAT_SPARSE_SUPER feature is turned on.

parses a version string and returns a version number,
so application programs can compare version numbers as
integers.
Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* icount.c (ext2fs_create_icount): Change function so that it also
takes a new argument which contains a "hint" icount
structure. This "hint" icount allows the create function
to set up the sorted list in advance. This reduces
significantly the amount of data moving needed to insert
these inodes into the list later.
* icount.c (ext2fs_icount_validate): New function which validates
that the icount structure's rep invariant.
* icount.c (get_icount_el): Completely revamped implementation
to subsume put_icount_el(). Put_icount_el() used to
use an O(N) implementation to insert in the middle
of the icount list. It now uses a O(ln N) to search
for where the icount should be inserted, and then uses
a memcpy to move the list down (instead of a for loop).
* icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
ext2fs_icount_increment, ext2fs_icount_decrement): Check
to see if the inode is within bounds; if it isn't, return
EINVAL.
* bitops.h (ext2fs_test_generic_bitmap): Fix error message given
when a bad inode number is passed to test_generic_bitmap
to be EXT2FS_TEST_ERROR instead of the wrong
EXT2FS_UNMARK_ERROR.

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.

* bb_compat.c: New file which translates between old badblocks_*()
names to ext2fs_badblocks_*()

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

* 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.

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).

* 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.

* 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.

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_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.

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
to allocate an inode in group #0 and there are no free
inodes at all in the system.

(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

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
block_iterate_ind and company.
* bitops.h (ext2fs_fast_mark_block_bitmap,
ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
ext2fs_fast_test_inode_bitmap): Add fast version of these
functions, which don't do range checking.
* bitops.h (ext2fs_get_block_bitmap_start,
ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
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
instead of llseek. The errno if the offset is too large
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.
* llseek.c (llseek): New function, if llseek() does not exist in the
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>
* mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
* 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.
* alloc.c: Include <errno.h> if possible.
* badblocks.c: Ditto.
* bb_inode.c: Ditto.
* bitmaps.c: Ditto.
* block.c: Ditto.
* expanddir.c: Ditto.

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

ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,

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):

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.
Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
* 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.
