The new resize tests create 2TB test files, but tmpfs in kernels
before 3.1 have a max file size of 256GB. Ext3 may also have
a size limit for smaller blocksize filesystems.
Fix the resize_test script to verify that $TMPFILE can be resized
to the final test size, and if that fails try creating the file on
the local filesystem instead of in $TMPDIR. If that cannot hold
the large filesystem, skip the test.

Eric Sandeen reported that Fedora's mke2fs when compiled for ppc was
creating a file system which caused problems with resize2fs -M.
Closer examination showed that the problem was file system which
looked like this:
Filesystem features: ext_attr dir_index filetype sparse_super
Inode count: 512
Block count: 1247
...
Group 0: (Blocks 1-1024)
Primary superblock at 1, Group descriptors at 2-2
Block bitmap at 66 (+65), Inode bitmap at 67 (+66)
Inode table at 68-99 (+67)
Group 1: (Blocks 1025-1246)
Backup superblock at 1025, Group descriptors at 1026-1026
Block bitmap at 1090 (+65), Inode bitmap at 1091 (+66)
Inode table at 1092-1123 (+67)
It's not obvious to me why Fedora's ppc mke2fs is creating file
systems like this (I can't reproduce this on debian ppc systems), but
resize2fs -M should be able to deal with such file systems, which is
what this test is designed to check.

Commit d3f32c2db8 was intended to detect extents found outside their
proper location in the extent tree, including invalid extents at the
end of an extent block. However, it incorrectly reported legal
uninitialized extents created by fallocate() at the end of file with
the FALLOC_FL_KEEP_SIZE flag as false positives. xfstests
generic/263 (among others) caught this problem, while the e2fsprogs
test f_uninit_ext_past_eof did not. The latter test failed to
detect the problem in part because it uses a test file whose i_size
is 0.
Add a test derived from the fsx-based test case in xfstests
generic/263 consisting of a file with non-zero length, more than
four extents total, and two uninitialized extents past EOF to
reliably reproduce commit d3f32c2db8's false positive behavior.

The function deallocate_inode() in e2fsck/pass2.c was buggy in that it
would clear out the inode's mode and flags fields before trying to
deallocate any blocks which might belong to the inode.
The good news is that deallocate_inode() is mostly used to free inodes
which do not have blocks: device inodes, FIFO's, Unix-domain sockets.
The bad news is that if deallocate_inode() tried to free an invalid
extent-mapped inode, it would try to interpret the root of the extent
node as block numbers, and would therefore mark various file system
metadata blocks (the superblock, block group descriptors, the root
directory, etc.) as free and available for allocation. This was
unfortunate.
(Try running an older e2fsck against the test file system image in the
new test f_invalid_extent_symlink, and then run e2fsck a second time
on the fs image, and weep.)
Fortunately, this kind of file system image corruption appears to be
fairly rare in actual practice, since it would require a very unlucky
set of bits to be flipped, or a buggy file system implementation.

The environment variable EXT2FS_NO_MTAB_OK will suppress the error
code EXT2_NO_MTAB_FILE when the /etc/mtab file can not be found. This
allows the e2fsprogs regression test suite to be run in chroots which
might not have an /etc/mtab file.
By default will still want to complain if the /etc/mtab file is
missing, since we really don't want to discourage distributions and
purveyors of embedded systems from running without an /etc/mtab file.
But if it's missing it only results in a missing sanity check that
might cause file system corruption if the file system is mounted when
programs such as e2fsck, tune2fs, or resize2fs is running, so there is
no potential security problems that might result if this environment
variable is set inappropriately.

Don't change the root directory's UID/GID automatically just because
mke2fs was run as a non-root user. This can be confusing for users,
and is not flexible for non-root installation tools that need to
create a filesystem with different ownership from the current user.
Add the "-E root_owner[=uid:gid]" option to mke2fs so that the user
and group can be explicitly specified for the root directory. If
the "=uid:gid" argument is not specified, the current UID and GID
are extracted from the running process, as was done in the past.

The sed filters for test outputs that are used to remove build and
test specific information (such as version strings, dates, times,
UUIDs) were unconditionally deleting the first line of output. This
would normally contain the tool version string, but in some cases
contained other information that was being lost. This can lead to
difficulty debugging test failures.
The sed filtering has been changed to only remove the actual version
strings. As well, similar filter strings were duplicated throughout
many scripts, and "sed" and "tr" were often called multiple times in
a pipeline. These have been consolidated into a single filter.sed
file to avoid having to maintain these filters in multiple places.
In a few cases, accidentally deleted messages have been restored to
the expect output for the tests. In other cases, trivial whitespace
has been changed in the expect files.

If all of the extents in the last extent tree block (ETB) in a
non-trivial extent tree contain uninitialized extents which are after
the end of the file as defined by i_size, the hueristics will
incorrectly estimate the last entry (and hence the node's e_len field)
in the last entry of each level of the extent tree.
As Tao Ma has noted, since e2fsck was requiring that the length
(e_len) field of interior nodes be non-zero, this was causing false
failures where e2fsck would declare that the extent tree was
corrupted.
This was fixed in commit 9c40d14841: "e2fsck: only check for

Change the e2fsck/mke2fs/tune2fs/e2image/debugfs regression tests to
be driven by Makefile rules instead of by a script loop. This allows
the tests to be run in parallel like a build and reduces testing time
significantly.
One major change to the tests themselves is to printing the test name,
description, and status together after the test has passed or failed,
to avoid mixing lines from the tests. The other major change is to
use unique temporary filenames for each test, which was mostly handled
already via b4db1e4c74, but in some
cases temporary files are changed to use $test_name.tmp to avoid any
collision between running tests.
On my old 2-CPU system it reduced the testing time from 160s to 40s.
Much of the savings is from the MMP test delays running in parallel.
It still takes the time of the slowest test, f_mmp_garbage, though
there will be ongoing benefit in the future as more tests are added
since the wallclock time will not increase linearly for each test.
Tests were run with various combinations of "make -j", and "make -j2"
through "make -j44" repeatedly without any test failures.

simply search for initialized extents past the i_size as this should not
happen. Uninitialized extents can be past the i_size as we can do
fallocate with KEEP_SIZE flag.
