libext2fs: report bad magic over bad sb checksum
We don't want ext2fs_open2() to report bad sb checksum on something
that's not even an ext* superblock. This apparently happens pretty
easily if we try to open an XFS filesystem. Thus, make it so that a
bad magic number code always trumps the sb checksum error code.

libext2fs: avoid buffer overflow if s_first_meta_bg is too big
If s_first_meta_bg is greater than the of number block group
descriptor blocks, then reading or writing the block group descriptors
will end up overruning the memory buffer allocated for the
descriptors. Fix this by limiting first_meta_bg to no more than
fs->desc_blocks. This doesn't correct the bad s_first_meta_bg value,
but it avoids causing the e2fsprogs userspace programs from
potentially crashing.

libext2fs: don't always read backup group descriptors on a 1k-block meta_bg fs
On a filesystem with 1K blocks and meta_bg enabled, opening a
filesystem with automatic superblock detection tries to compensate for
the fact that the superblock lives in block 1. However, the method by
which this is done is later misinterpreted to mean "read the backup
group descriptors", which is not what we want in this case.
Therefore, in ext2fs_open3() separate the 'group zero' adjustment into
its own variable so that we don't get fed backup group descriptors
when we try to load meta_bg group descriptors.
Furthermore, enhance ext2fs_descriptor_block_loc2() to perform its own
group zero correction. The other caller of this function neglects to
do any group-zero correction of their own, so this fixes them too.

libext2fs: detect correct superblock adjustments when loading backup groups
If ext2fs_descriptor_block_loc2() is called with a meta_bg filesystem
and group_block is not the normal value, the function will return the
location of the backup group descriptor block in the next block group.
Unfortunately, it fails to account for the possibility that the backup
group contains a backup superblock but the regular superblock does
not. This is the case with block groups 48-49 on a meta_bg fs with 1k
blocks; in this case, libext2fs will fail to open the filesystem.
Therefore, teach the function to adjust for superblocks in the backup
group, if necessary.

Currently, only the new 64-bit bitmap implementation supports the
block<->cluster conversions that bigalloc requires. Therefore, if we
have a bigalloc filesystem, require EXT2_FLAGS_64BITS be passed in to
ext2fs_open(). This does not mean that bigalloc file systems have to
be 64-bits; just that the userspace utilities have to be able to use
the new 64-bit capable library functions.

libext2fs: don't mark the superblock as dirty if the fs was opened r/o
If the file system is read/only opened with a backup superblock, and
the file system has uninit_bg enabled, the super block must not be
marked as dirty; otherwise, ext2fs_close() will call ext2fs_flush(),
which will fail, since the file descriptor for the block device was
opened read/only, and then the file descriptor won't actually be
closed.
This is normally not a problem since most of the time the program will
exit shortly after calling ext2fs_close(), and many programs don't
bother checking the error return from ext2fs_close(), especially if
the file system was opened read/only.
A big exception to this is e2fsck, since it opens and close the file
systems during its startup, and to make matters worse, registers an
error handler which will noisly complain about the failed writes
caused by ext2fs_flush().
Fix this by not marking the superblock as dirty if the file system was
opened read/only. The changes to the block group descriptors to clear
the uninit bits will still happen, so that e2fsck -n will properly
scan the whole file system. However, those changes will get dropped
when the file system handle is closed.

flags are cleared to ensure that all of the inodes in the filesystem

reset the group checksum, and this produced many spurious error

Group descriptor 0 checksum is invalid. FIXED.
Group descriptor 1 checksum is invalid. FIXED.

ext2fs: add multi-mount protection (INCOMPAT_MMP)
Multi-mount protection is feature that allows mke2fs, e2fsck, and
others to detect if the filesystem is mounted on a remote node (on
SAN disks) and avoid corrupting the filesystem. For e2fsprogs this
means that it checks the MMP block to see if the filesystem is in use,
and marks the filesystem busy while e2fsck is running on the system.
This is useful on SAN disks that are shared between high-availability
servers, or accessible by multiple nodes that aren't in HA pairs. MMP
isn't intended to serve as a primary HA exclusion mechanism, but as a
failsafe to protect against user, software, or hardware errors.
There is no requirement that e2fsck updates the MMP block at regular
intervals, but e2fsck does this occasionally to provide useful
information to the sysadmin in case of a detected conflict.
For the kernel (since Linux 3.0) MMP adds a "heartbeat" mechanism to
periodically write to disk (every few seconds by default) to notify
other nodes that the filesystem is still in use and unsafe to modify.

Shorten compile commands run by the build system
The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

libext2fs: fix binary and source compatibility with the dump program
The dump program relies on fs->frag_size and the
EXT2_FRAGS_PER_BLOCK() macro. Kind of silly for it to do so, but it's
part of the kludgy way the dump program (which was originally written
for the BSD FFS was ported over to support ext2/3.) Given how it
makes assumptions about the ext2/3/4 file system being similar to the
BSD FFS, it's a bit of a miracle it works for ext4 --- or at least
appears to work...

libext2fs: change fs->clustersize to fs->cluster_ratio_bits
The log2 of the ratio of cluster size to block size is far more useful
than just storing the cluster size. So make this change, and then
define basic utility macros: EXT2FS_CLUSTER_RATIO(),
EXT2FS_CLUSTER_MASK(), EXT2FS_B2C(), EXT2FS_C2B(), and
EXT2FS_NUM_B2C().

libext2fs: require cluster size == block_size when opening a !bigalloc fs
In ext2fs_open() check to make sure the cluster size superblock field
is the same as the block size field when the bigalloc feature is not
set. This is necessary since we will start introducing calculations
based on the cluster size field.

ext2fs_open2() to request Direct I/O support.
Note that device mapper devices in Linux don't support Direct I/O, and
in some circumstances using Direct I/O can actually make performance
*worse*!

libext2fs: clean up ext2fs_bg_flags_ interfaces
The ext2fs_bg_flag* functions were confusing.
Currently we have this:
void ext2fs_bg_flags_set(ext2_filsys fs, dgrp_t group, __u16 bg_flags);
void ext2fs_bg_flags_clear(ext2_filsys fs, dgrp_t group,__u16 bg_flags);
(_set (unused) sets exactly bg_flags; _clear clears all and ignores bg_flags)
and these, which can twiddle individual bits in bg_flags:
void ext2fs_bg_flag_set(ext2_filsys fs, dgrp_t group, __u16 bg_flag);
void ext2fs_bg_flag_clear(ext2_filsys fs, dgrp_t group, __u16 bg_flag);
A better interface, after the patch below, is just:
ext2fs_bg_flags_zap(fs, group) /* zeros bg_flags */
ext2fs_bg_flags_set(fs, group, flags) /* adds flags to bg_flags */
ext2fs_bg_flags_clear(fs, group, flags) /* clears flags in bg_flags */
and remove the original ext2fs_bg_flags_set / ext2fs_bg_flags_clear.

libext2fs: Add checks to prevent integer overflows passed to malloc()
This addresses a potential security vulnerability where an untrusted
filesystem can be corrupted in such a way that a program using
libext2fs will allocate a buffer which is far too small. This can
lead to either a crash or potentially a heap-based buffer overflow
crash. No known exploits exist, but main concern is where an
untrusted user who possesses privileged access in a guest Xen
environment could corrupt a filesystem which is then accessed by the
pygrub program, running as root in the dom0 host environment, thus
allowing the untrusted user to gain privileged access in the host OS.
Thanks to the McAfee AVERT Research group for reporting this issue.

Don't write changes to the backup superblocks by default
This patch changes ext2fs_open() to set EXT2_FLAG_MASTER_SB_ONLY by
default. This avoids some problems in e2fsck (reported by Jim Garlick)
where a corrupt journal can end up writing the bad superblock to the
backups. In general, only e2fsck (after the filesystem is clean),
tune2fs, and resize2fs should change the backup superblocks by default.
Most callers of ext2fs_open() should not be touching anything where the
backups should be touched. So let's change the defaults to avoid
potential problems.

wrong group_block to ext2fs_descriptor_block_loc if we're
using the backup superblock/block group descriptors.
(ext2fs_descriptor_block_loc): If we're using the backup
superblock descriptors, use the backup descriptor block in
the next block group.

Do sanity checking of the number of blocks and inodes in a group for
8192-byte and 16384-byte blocksize filesystems.
Change the default bytes-per-inode ratio of a new filesystem to be at most
one inode per block for large blocksizes.

Mke2fs now creates the lost+found directory with 0700 permissions,
since files which get dropped into that directory may have come
from a protected directory, and the system administrator may not
deal with immediately. (Addresses Debian bug #118443)

ChangeLog, Makefile.in, swapfs.c, 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.

ChangeLog, ext2_err.et.in, ext2fs.h, initialize.c, mkjournal.c, openfs.c:
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().

Many files:
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.

Many files:
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.

Many files:
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).

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++.
closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
make sure the contents of the disk are flushed to disk.
dblist.c (ext2fs_add_dir_block): Change new to be new_entry to

information.
all files: Don't include stdlib.h anymore; include it in ext2_fs.h,
since that file requires stdlib.h
ChangeLog, Makefile.in, dirinfo.c:
dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead of
e2fsck_get_num_dirs, which has been removed.
Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want to
compile and install flushb.
ChangeLog, configure.in:
Remove @EXTRA_PROGS@, since we aren't using it in 2fsck/Makefile.in anymore
ChangeLog, Makefile.in:
Install debugfs in /sbin, instead of /usr/sbin.
libext2fs.texinfo:
Update version string to be 1.12
