generic: test eofblocks race with file extending aio dio writes
It's possible for post-eof blocks to end up being used for direct
I/O writes. dio write performs an upfront unwritten extent
allocation, sends the dio and then updates the inode size (if
necessary) on write completion. If a file release occurs while a
file extending dio write is in flight, it is possible to mistake the
post-eof blocks for speculative preallocation and incorrectly
truncate them from the inode. This means that the resulting dio
write completion can discover a hole and allocate new blocks rather
than perform unwritten extent conversion.

XFS: Assertion failed: tp->t_blk_res_used <= tp->t_blk_res, \
file: fs/xfs//xfs_trans.c, line: 309
The root cause is that xfs_free_eofblocks() uses i_size to truncate
post-eof blocks from the inode, but async, file extending direct
writes do not update i_size until write completion, long after inode
locks are dropped. Therefore, xfs_free_eofblocks() effectively
truncates the inode to the incorrect size.
Besides reproduce above kernel warning, the verification of written
data is an important distinction between this test and generic/299.
For cover this filesystem corruption testing, write this new case to
check data integrality manually, not only depend on a kernel
warning.

I don't know if anybody uses bz2 or xz, but hey.
1. Create test set of N files and try to get their NFS handles:
open_by_handle -c <test_dir> [N]
This is used by new helper _require_exportfs() to check
if filesystem supports exportfs
2. Get file handles for existing test set, drop caches and try to
open all files by handle:
open_by_handle <test_dir> [N]
3. Get file handles for existing test set, unlink all test files,
drop caches, try to open all files by handle and expect ESTALE:
open_by_handle -d <test_dir> [N]
4. Get file handles for existing test set, hardlink all test files,
then unlink the original files, drop caches and try to open all
files by handle (should work):
This test is done with 2 invocations of the program, first to
hardlink (-l) and then to unlink the originals (-u), because
we would like to be able to perform the hardlinks on overlay
lower layer and unlink on upper layer.
NOTE that open_by_handle -u doesn't check if the files are
hardlinked, it just assumes that they are. If they are not
then the test will fail, because file handles would be stale.

xfs/348: update error message when transmogrifying symlink into directory
We introduced the inline directory verifier in 4.11 to prevent the
system from trying to use corrupt inline directories. This has the
effect of changing the error message in one step of the i_mode fuzz
tester, so update the test accordingly.
Note that prior to the existence of the verifier, this test would
occasionally result in memory corruption that did not become evident
until later.

generic: Add first statx test
Add a statx test script that does the following:
(1) Creates one each of the various types of file object and creates a
hard link to the regular file.
Note that the creation of an AF_UNIX socket is done with netcat in a
bash coprocessing thread. This might be best done with another
in-house helper to avoid a dependency on nc.
(2) Invokes the C test program included in this patch after the creation
and hands it a list of things to check appropriate to each object.
(3) Asks the test program to check the creation time of each object
against that of the preceding object.
(4) Makes various tests on the timestamps of the hardlinked file.
The patch also creates a C[*] test program to do the actual stat checking.
The test program then does the following:
(1) Compares the output of statx() to that of fstatat().
(2) Optionally compares the timestamps to see that they're sensibly
ordered with respect to each other.
(3) Optionally compares the timestamps to those of a reference file.
(4) Optionally compares the timestamps to a specified time.
(5) Optionally compares selected stats to values specified on the command
line.
(6) Optionally compares all the stats to those of a reference file,
requiring them to be the same (hard link checking).
The test program can also be given a --check-statx parameter to give a
quick exit code-based answer on whether statx() exists within the kernel.
[*] Note that it proved much easier to do this in C than trying to do it in
shell script and trying parsing the output of xfs_io. Using xfs_io has
other pitfalls also: it wants to *open* the file, even if the file is
not an appropriate type for this or does not grant permission to do so.
I can get around this by opening O_PATH, but then xfs_io fails to
handle XFS files because it wants to issue ioctls on every fd it opens.

The filesystem was renamed OrangeFS from PVFS2 recently. The mount

the kernel module being named orangefs.

common/config: don't hard-code SELinux context
If SELinux is enabled, by default xfstests mounts its filesystems
with "-o context=system_u:object_r:nfs_t:s0" so that no SELinux
xattrs get created and interfere with tests. However, this
particular context is not guaranteed to be available because the
context names are a detail of the SELinux policy. The SELinux
policy on Android systems, for example, does not have a context with
this name.
To fix this without having to manually override
SELINUX_MOUNT_OPTIONS, just grab the SELinux context of the root
directory. This is arbitrary, but it should always provide a valid
context. And if for some reason someone is actually running
xfstests in a specific SELinux context that needs files labeled with
a particular context, then they may still override
SELINUX_MOUNT_OPTIONS.
SELINUX_MOUNT_OPTIONS is already set in common/config. Setting it again
in common/quota is not necessary. Nor is SELINUX_MOUNT_OPTIONS specific
to quota tests, so common/quota is not the right place for it.
