mke2fs: prevent creation of unmountable ext4 with large flex_bg count
In mke2fs command, if flex_bg count is too large to filesystem blocks
count, unmountable ext4 which has the out of filesystem block offset
is created (Case1). Moreover this large flex_bg count causes an
unintentional metadata layout (bmap-imap-itable-bmap-imap-itable .. in

mke2fs: handle flex_bg collision with backup descriptors
If a large flex_bg factor is specified and the block allocator was
laying out block or inode bitmaps or inode tables, and collides with
previously allocated metadata (for example the backup superblock or
group descriptors) it would reset the allocator back to the beginning
of the flex_bg instead of continuing past the obstruction.
For example, with "-G 131072" the inode table will hit the backup
descriptors in groups 1, 3, 5, 7, 9 and start interleaving with the
block and inode bitmaps. That results in poorly allocated bitmaps
and inode tables that are interleaved and not contiguous as was
intended for flex_bg:

Instead, skip the intervening blocks if there aren't too many of them.
That mostly keeps the flex_bg allocations from colliding, though still

e2fsprogs: introduce ext2fs_close_free() helper
Currently there are many uses of ext2fs_close() which might be wrong.
First of all ext2fs_close() does not set the ext2_filsys pointer to NULL
so the caller is responsible for clearing it, however there are some
cases there we do not do it.
Second of all very small number of users of ext2fs_close() actually
check the return value. If there is a problem in ext2fs_close() it will
not even free the ext2_filsys structure, but majority of users expect it
to do so.
To fix both problems this commit introduces a new helper
ext2fs_close_free() which will not only check for the return value and
free the ext2_filsys structure if the call to ext2fs_close2() failed,
but it will also set the ext2_filsys pointer to NULL.
Replace every use of ext2fs_close() in e2fsprogs tools with

fix cross-compilation support
Commit
2500ebfc89 (util: fix make dependencies for subst) broke cross
compilation because it unconditionally used config.h without setting a
includes path so that the config.h file could be found.
The proposed fix of adding the include path (such as was proposed at
http://patchwork.ozlabs.org/patch/355662/ or in Debian Bug #753375)
isn't really the right way to go, since the information in config.h is
for the target environment, and not the build environment. So using
config.h when building helper programs used as part of the build can
potentially cause more problems than it solves.
In general, build helpers must be written to be as portable as
possible, and to not require any autoconf defined #ifdef's whenever
possible. The subst program broke this rule to (1) address a Coverity
security complaint by using futimes(2) instad of utimes(2) if present,
and (2) to preserve the nanosecond portion of the file timestamp.
Oh, well. We won't be able to do the latter when cross compiling, and
as to the former, if an attacker has write access to your build tree
while you are building programs that will be run as root, you've got
bigger problems. :-)
Fix the problem that commit
2500ebfc89 was trying to address by
explicitly adding @DEFS@ to CFLAGS, so that -DHAVE_CONFIG_H is passed
to make depend. This fixes up the make depend without forcing the use
of config.h when cross-compiling.

quota: fix e2fsck so we update the quota file correctly
In scan_dquota_callback() we were copying dqb_off from the on-disk
dquot structure to the dqot structure that we have constructed in
memory. This is a bad idea, because if we detect that the quota inode
is corrupted and needs to be replaced, when we later write out the
inode, the fact that we have a non-zero dqb_off value means that quota
routines will not bother updating the quota tree index, since
presumably the quota tree index already has an entry for this dqot.
The problem is that e2fsck, the only user of these functions, has
zapped the quota inode so it can be written from scratch. So this
means the index for the quota records are not written out, so the
kernel can not find any of the records in the quota inodes. Oops.
The fix is simple; there is no reason to copy the dqb_off field into
the quota_dict copy of struct dquot.

resize2fs: refine minimum required blocks for flex_bg file systems
The previous commit exposed bugs in the calculation for flex_bg file
systems. The problem is that since (by default) we keep the metadata
blocks for the flex_bg in the first block group of the flex_bg, and
because we don't want to overwrite metadata blocks used by the
original file system with data blocks make life easier in case the
resize is aborted for some reason, we need to treat all of the
metadata blocks in the existing flex_bg has in use for the purposes of
calculate_minimum_resize_size().
Even though this means we need to reserve more data blocks to avoid
running out of space, the net result of these two commits is a net
savings in how much we can shrink a file system.

tests: fix resize test tmpfs max-file-size checking
Old distros may not have the "truncate" tool, so use "dd" instead.
If tmpfs cannot handle a 2GB temp file (e.g. old RHEL5 and SLES 11
kernels) then skip the test instead of failing it. If this fails,
try to report better error messages instead of failing silently.

mke2fs: disable resize_inode feature if 64bit feature is enabled
Since auto_64-bit_support is on by default, resize_inode feature will
be disabled when creating a >16T ext4 according to mke2fs.conf(5).
This should also be done when making ext4 with "-O 64bit" to enable
64bit feature explicitly. Otherwise online resize to enlarge a
over-16T fs to larger would fail.

The e2fsck_global_ctx varible was only being set if HAVE_SIGNAL_H is

This was causing e2fsck_set_bitmap_type() to seg fault since
e2fsck_global_ctx was not NULL.
