mke2fs: Issue a warning if the mke2fs.conf file wasn't updated
Many people are forgetting to update their mke2fs.conf file, and this
means that filesystems aren't getting created with the proper features
enabled. So detect this case and issue a warning.

configure.in: Respect LDFLAGS environment variable if passed into configure
If the --with-ldopts option is not passed on the command line, respect
the LDFLAGS environment variable instead of forcing LDFLAGS to be
unset. "configure --help" documents LDFLAGS as part of the standard
configure script calling convention.

libext2fs: Replace use of sprintf with strcpy/strcat to help SILO
Some bootloaders, like SILO, don't provide sprintf in their limited
bootloader environment. Since the uses in rw_bitmaps.c is only doing
sprintf("foo %s"), it's easy to replace that usage with strcpy/strcat.

resize2fs: supply block allocator for extents function
In the rare case where new blocks are needed while mutating an extent
tree, supply a specialized block allocator so that extent_node_split()
allocates valid blocks for the interior nodes of the extent tree.

resize2fs: Fix support for filesystems with the uninit_bg feature
If the filesystem has the uninit_bg feature, then parts of the block
and inode bitmap may not be initialized. Teach resize2fs how to deal
with these case appropriately. (Most of these fixes were fortunately
not necessary for the common case where the resize_inode is present to
reserve space, and where the filesystem is being expanded instead of
being shrunk.)

libext2fs: Add support for uninit_bg feature to allocation functions

initialize them so ext2fs_new_block() and ext2fs_new_inode() work
correctly.

Fix ext2fs_extent_set_bmap() when setting a block before the first extent
When setting a logical block which is before the first extent in the
extent tree, make sure the new extent goes in front, at the very
beginning of the extent tree. This fixes a bug where previously the
new extent would be inserted out of order in this case.

resize2fs: Fix double bumping of directory in-use counts
When moving directories into new block groups (which would only happen
when shrinking a filesystem), resize2fs would increase the directory
in-use count by 2 times the necessary value, due to a change in
ext2fs_inode_alloc_stats() made in e2fsprogs 1.26. This is largely
harmless, but it does result in a filesystem corruption for e2fsck to
fix.

e2fsck: Fix max size calculation for extent files
A misunderstanding C's precedence rules and the meaning of

filesystems with 4k block sizes.

blkid: Fix probing logic so we find renamed devices
This fixes a bug where if there is an entry in the /etc/blkid.tab file
for a particular device (major, minor) number but the filename does
not exist, blkid wouldn't try to find the correct filename.
tune2fs: Improve the error messages for tune2fs -I
If the current inode size is less than or equal to the requested inode
size, either explain that shrinking the inode size is not supported,
or that the inode is already the requested size. Also, open the
filesystem provisionally first to do the inode size check and don't
setup up the undo log until we know that we're actually going to
perform the inode resizing operation.
Disordered inode tables may appear when inode_blocks_per_group is lesser
or equal to the number of groups in a flex group.
This bug can be reproduced with:
mkfs.ext4 -t ext4dev -G512 70G
In that case, you can see with dump2fs that inode tables for groups 510
and 511 are placed just after group 51's inode table instead of being
placed after group 509's inode table.
Add more intelligent handling of the mke2fs.conf installation process
For people who are compiling mke2fs for their own use outside of a
package manager, we need to make sure the system /etc/mke2fs.conf is
sufficiently up-to-date that it won't cause problems, but at the same
time we don't want to blow away any user-specific customizations.
So if /etc/mk2fs.conf exists, but does not mention ext4dev, we will
move it aside to /etc/mke2fs.conf.e2fsprogs-old and then install the
new mke2fs.conf. If the /etc/mke2fs.conf file exists but does mention
ext4dev, we install the new mke2fs.conf file as
/etc/mke2fs.conf.e2fsprogs-new. In both cases we print a warning
mesage to the user so they can manually update /etc/mke2fs.conf with
any changes if they so desire.
ext2fs_read_inode: Check the validity of the inode number earlier
It looks like the right place to check for ino=0 in
ext2fs_read_inode_full() is before creating the inode cache, otherwise
since we set icache[i].ino = 0 in create_icache(), it will match the
loop below and thus we return a wrong value.
Disable %.sh -> % GNU make rule in the top-level Makefile
It's not needed for e2fsprogs, but one niche distribution likes to use
configure.sh files which can cause GNU make to inappropriately fire an
implicit rule to overwrite the configure file resulting in a fork bomb
leading to the OOM crash.
libext2fs: Don't check the group checksum when !GDT_CSUM
ext2fs_group_desc_csum_verify() is always checking the bg_checksum (to
make sure it is zero) even when the GDT_CSUM feature is not present.
This is normally OK, but apparently there are filesystems in the wild
where this field has not be initialized to zero.
e2fsck: Set LD_LIBRARY_PATH before running "make check" programs
This is needed so that "make check" works in the e2fsck library even
if the shared libraries are not yet installed, and so that we run
those programs against the version of the libraries built in the build
tree.
Define _XOPEN_SOURCE to 600 consistently for Solaris C99 support
Solaris's header files are very picky about which C compiler can be
used for SUSv3 conformance. Use of C99 is not compatible with SUSv2
(_XOPEN_SOURCE=500), and C89 is not compatible with SUSv3
(_XOPEN_SOURCE=600). Since we need some SUSv3 functions, consistently
use SUSv3 so that e2fsprogs will build on Solaris using c99.
Gcc only supports __builtin_expect for gcc versions 2.96 and up.
Since it's tricky to check for gcc 2.95 vs 2.96 (and either are only
used on really ancient systems anyway), we only use this optimization
on 3.x and newer versions of gcc.
Make ext2fs_check_desc() more stringent to force use of backup superbocks
E2fsck could to do more damage to a filesystem by trying to relocate
inode tables due to corrupted block group descriptors, and the
relocation could seriously damage the filesystem.
This patch enhances ext2fs_check_desk() so it detects more
self-inconsistent block group descriptors, including the cases where
e2sck might be tempted to relocate the inode table, and reports the
block group descriptors as invalid; this will cause e2fsck to attempt
to use the backup superblocks, which hopefully have not been trashed.
mke2fs,tune2fs: Enable huge_file, dir_nlink, and extra_isize features
Also change mke2fs.conf to enable huge_file,dir_nlink,extra_isize, and

the library as well.

Use consistent and standard terminology for the starting and ending

The Hurd only supports filesystems with a blocksize of 4096 bytes, and
128 byte inodes. It also doesn't understand the journal. So force
the defaults to be something which the Hurd can handle if "-o hurd" is

blkid: Make regression test tolerate older versions of mkswap
The blkid/tests contains new tests for swap, but the type-1 swapfile
test depends on mkswap supporting the "-U" option to specify the UUID.
This is not available even on relatively recent versions of mkswap
(2.13.1 16-Jan-2008) so the test needs to be changed to handle this.
If the "-U" option is not supported, don't verify the UUID in the blkid
