Makefile.in: Limit some .o files from being included into the library
if --disable-debugfs, --disable-swapfs, --disable-imager, or
--disable-resizer are used.
dumpe2fs.c: Use WORDS_BIGENDIAN to determine whether or not we're
(not) using i386 byte order.
dumpe2fs.c, mke2fs.c: Stop using the compatibility badblocks function,
and use the ext2fs_badblocks_* functions instead.
ChangeLog, inode.c, tst_iscan.c:
inode.c, tst_iscan.c: Stop using the compatibility badblocks function,
and use the ext2fs_badblocks_* functions instead.
ChangeLog, badblocks.c:
badblocks.c: Stop using the compatibility badblocks function, and use
the ext2fs_badblocks_* functions instead.
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.)
ChangeLog:
Add missing log entry for unix.c.
Makefile.in: Add message.c and swapfs.c to the list of source files to
build the make depend.
swapfs.c, unix.c: Only support the -s and -S options to e2fsck if
ENABLE_SWAPFS is defined.
Many files:
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.
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.
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.
ChangeLog, ext2_types.h.in:
ext2_types.h.in: Use unsigned ints in favor of unsigned longs when
trying to find a 32-bit wide type.
Makefile.in: Move include/asm/types.h.in to lib/ext2fs/ext2_fs.h.in.
wordwrap.pl: Add some rules which help fix up the dependencies.
Many files:
Move include/asm/types.h.in to lib/ext2fs/ext2_fs.h.in.
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.
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.
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.
ext2fs.h: #include <> instead of "" for ext2fs and et header files,
since they will be installed in /usr/include
ChangeLog, e2p.h:
e2p.h: #include <> instead of "" for ext2fs and et header files, since
they will be installed in /usr/include
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.
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 orrupted.
(ext2fs_write_dir_block): If while byte-swapping the directory block,
if there's an error, abort and return EXT2_ET_DIR_CORRUPTED.
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.
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.
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_*.
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.
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.
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.
ChangeLog, dumpe2fs.c:
dumpe2fs.c (print_journal_information): Use s_first_data_block to find
the correct block to read the journal superblock.
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().
MCONFIG.in: Change --enable-gcc-wall handling so that it's no longer a
configure option, but something which is done when the developer uses
the command "make gcc-wall".
configure.in: Remove test for ino_t, since we don't use it any more
(we always use our own ext2_ino_t). Remove --enable-gcc-wall support.
Add test for sys/ioctl.h
.del-types.h.in~ca55114a:
Remove definition of ino_t
ChangeLog, Makefile.in, ext2fs.h, flushb.c, jump.funcs:
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.)
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.
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.
mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall
complaints including a missing return 0 at the end of
ext2fs_add_journal_device.
ChangeLog, ext2fs.h:
ext2fs.h: Indent the #warning to fix gcc -Wall complaint.
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.
.del-types.h.in~ca55114a:
Change what we use to protect the header file to be _ASM_TYPES_H
instead of _LINUX_TYPES_H. (Needed to make libc5 builds happy).
version.h:
Update for WIP release.
ismounted.c: add ext2fs_check_mount_point() function, which will
optionally return the mount point of a device if mounted
ChangeLog, closefs.c, ext2fs.h:
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.
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.
ChangeLog, main.c:
main.c (main): Replace use of struct ext2fs_sb with struct ext2_super_block.
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.
ChangeLog:
jfs_compat.h: Remove uneeded header file.
ext2fs.h, mkjournal.c (ext2fs_add_journal_fs,
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.
ChangeLog, jfs.h, jfs_compat.h, list.h:
jfs.h, jfs_compat.h, list.h: New files added to support ext3.
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.)
ChangeLog, Makefile.in, e2image.c:
e2image.c, Makefile.in: New program which saves ext2 metadata to a
file for people who need a last-ditch saving throw.
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.
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.
