Bernhard Rosenkränzer <Bernhard.Rosenkranzer@linaro.org> |
Add files that would normally be generated by the e2fsprogs build system
Android doesn't run ./configure and friends, so it has to rely on
pre-populated versions of the autogenerated files.
This is somewhat bogus (e.g. hardcoded little-endian reference in
lib/ext2fs/ext2_types.h) and should at some point be fixed, but it's
what Android has always done, not a regression from the 1.41.14 branch.
Also, don't #include config.h which we don't generate (we pass what it
usually contains as -D parameters from Android.mk) anywhere.
Add a new Android.mk file for the quota library.

Clean up sparse warnings
Mostly by adding static and removing excess extern qualifiers. Also
convert a few remaining non-ANSI function declarations to ANSI.

mmp: fix 64-bit handling of s_mmp_block
Fix the checking of s_mmp_block in e2fsck_pass1() and
ext2fs_mmp_read() to handle the high 32 bits of s_blocks_count.
Remove redundant check of s_mmp_block in do_dump_mmp() right before
ext2fs_mmp_read() is called.
Also fix s_blocks_count_hi in check_backup_super_block(), since it
cannot use the ext2fs_blocks_count() helper easily.

libext2fs: refactor Direct I/O alignment requirement calculations
Create a new function, ext2fs_get_dio_alignment(), which returns the
alignment requirements for direct I/O. This way we can factor out the
code from MMP and the Unix I/O manager. The two modules weren't
consistently calculating the alignment factors, and in particular MMP
would sometimes use a larger alignment factor than was strictly
necessary.

libext2fs: Always swab the MMP block on big-endian systems machines
The MMP code in libext2fs tries to gate MMP block swab'ing with this
test:
if (fs->super->s_magic == ext2fs_swab16(EXT2_SUPER_MAGIC))
However, EXT2FS_ENABLE_SWAPFS never seems to be defined anywhere (all
possible existed, the field fs->super->s_magic is always in host
byteorder, so the test always fails. So, we can change the #ifdef to
WORDS_BIGENDIAN (which is conditionally defined on BE platforms) and
get rid of the broken if test.

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.
