Eric Biggers 9000551d9b fstests: skip AIO-related tests when CONFIG_AIO=n
When running xfstests on a kernel configured with CONFIG_AIO=n, all
AIO-related tests fail, often due to an error similar to the
following:

    error Function not implemented during io_setup

This affected at least the following tests: generic/036,
generic/112, generic/113, generic/198, generic/207, generic/208,
generic/210, generic/211, generic/239, generic/323, generic/427,
xfs/240, xfs/241.

Fix this by enhancing the 'feature' program to allow testing for
asynchronous I/O support, then skipping all AIO-related tests when
AIO is unsupported.

This change is useful because CONFIG_AIO is sometimes disabled to
reduce the kernel's attack surface (e.g. see
https://android-review.googlesource.com/#/c/292158/).

Xiao Yang 704c27f69f common: cleanup _require_xfs_io_command
We don't need to check specific flags at the end of this function
if we have checked them before. e.g, generic/071 and generic/422
are marked as notrun unexpectedly because xfs_io doesn't support
long-format help for falloc before xfsprogs v4.9.  Actually, xfs_io
has supported falloc, so these case should not be marked as notrun.

[eguan: declare local vars as local, rename param_check to
param_checked]

Xiao Yang eaa2d30dba common: use _require_xfs_io_command() directly to check fiemap
1) _require_fiemap and _require_xfs_io_command "fiemap" do the
   same thing, but some test cases use the former and some use
   the latter, so i feel they should be unified.

2) The number of helpers like this is slowly growing, but it's
   easy to simply use _require_xfs_io_command directly and just
   specify the command we want to check.

This is just a cleanup for keeping it simple.

Amir Goldstein 5210726732 src/open_by_handle: flexible usage options
More usage options for testing open_by_handle, which are needed
for testing stable handles across copy up in overlayfs.

usage: open_by_handle [-c|-l|-u|-d] <test_dir> [num_files]

Examples:

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):

   open_by_handle -l <test_dir> [N]
   open_by_handle -u <test_dir> [N]

   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.

David Howells d1ba8b79a6 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).

For example:

	./src/stat_test /dev/null \
	       stx_type=char \
	       stx_rdev_major=3 \
	       stx_rdev_minor=8 \
	       stx_nlink=1 \
	       ref=/dev/zero \
	       ts=B,b

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.

Martin Brandenburg 85c95c7f24 fstests: add orangefs (pvfs2) support
The filesystem was renamed OrangeFS from PVFS2 recently.  The mount

the kernel module being named orangefs.

We've been maintaining this as a patch for quite some time.

The easiest way to use is to setup a single server installation with
multiple filesystems orangefs and scratch, put the following in
/etc/xfsqa.config, and run ./check -pvfs2 -g quick.

 Already mounted result:

Fix it by using findmnt command and specifying the $dev as mount
source, print the result in "$dev $mnt" format. This works for local
filesystems, network filesystems and overlayfs, avoids all kinds of
tricky and error-prone grep pattern/regex.

Also fixed the if-then-fi format in _check_mounted_on() while we're

Amir Goldstein 2ab614524d overlay: mount/unmount base fs before/after running tests
When TEST/SCRATCH_DEV are configured to the base fs block device,
use this information to mount base fs before running tests,
unmount it after running tests and cycle on _test_cycle_mount
along with the overlay mounts.

This helps catching overlayfs bugs related to leaking objects in
underlying (base) fs.

To preserve expected tests behavior, the semantics are:
- _scratch_mkfs mounts the base fs, cleans all files, creates
  lower/upper dirs and keeps base fs mounted
- _scratch_mount mounts base fs (if needed) and mounts overlay
- _scratch_unmount unmounts overlay and base fs

Tests that use _scratch_unmount to unmount a custom overlay mount
and expect to have access to overlay base dir, were fixed to use
explicit umount $SCRATCH_MNT instead.

The overlay test itself, does not support formatting the base fs,
so config options like MKFS_OPTIONS and FSCK_OPTIONS are ignored
on 'check -overlay'.
The config option MOUNT_OPTIONS is used to mount the base scratch fs.
The config option TEST_FS_MOUNT_OPTS is used to mount the base test fs.
The config option OVERLAY_MOUNT_OPTIONS is used to mount both test and
scratch overlay mounts.

Amir Goldstein bcba40e3df overlay: configure TEST/SCRATCH vars to base fs
Instead of setting the vars TEST/SCRATCH_DEV to overlay base dirs,
allow setting them to block devices to configure the base fs partition,
where overlay dirs will be created.

For example, the following config file can be used to run tests on
xfs test/scratch partitions:

 TEST_DEV=/dev/sda5
 TEST_DIR=/mnt/test
 SCRATCH_DEV=/dev/sda6
 SCRATCH_MNT=/mnt/scratch
 FSTYP=xfs

Using the same config file, but executing './check -overlay' will
use the same partitions as base fs for overlayfs directories
and set TEST_DIR/SCRATCH_MNT values to overlay mount points, i.e.:
/mnt/test/ovl-mnt and /mnt/scratch/ovl-mnt.

The base fs should be pre-formatted and mounted when starting the test.
An upcoming change is going to support mount/umount of base fs.

The new vars OVL_BASE_SCRATCH_MNT/TEST_DIR are set to point at the
overlayfs base dirs in either legacy or new config method.
Tests should always use these vars and not the legacy SCRATCH/TEST_DEV
vars when referring to overlay base dir.

- Prepend "ovl-" prefix to lower/upper/work path values to
  isolate the overlay test dirs when running on a base fs
  that is also used to run non overlay tests

- Make those vars values non-configurable, because lower/upper/work
  directory names are an internal test detail which should
  not concern the user and because we wish to simplify
  and document the overlay tests setup

- Add helper _filter_ovl_dirs and use it to filter output
  of test overlay/023 which matches the constant string "work"

Amir Goldstein 5e33bfcf23 fstests: use _test_mount() consistently
On start of every test run and on every test, in init_rc() helper,
the test partition is verified to be mounted, or is mounted by
the helper _test_mount().

_test_mount() uses mount options $TEST_FS_MOUNT_OPTS and not
$MOUNT_OPTIONS like _scratch_mount() does.

_test_cycle_mount(), which is called by some tests uses the
_test_mount() helper as well.

Contrary to those cases, in _require_test() helper, if test
partition is not mounted, the helper _mount_or_remount_rw()
is called to mount the test partition with $MOUNT_OPTIONS.
Although this should never happen, because of the test in
init_rc(), this case is inconsistent with the rest of the code,
so it has been changed to use _test_mount() as it should.

When running tests with a multi section configuration, and
either FSTYP or MOUNT_OPTIONS change between sections, the
helper _test_unmount() is called to unmount the old test mount
and then _mount_or_remount_rw() is called to mount it again
with new FSTYP and/or MOUNT_OPTIONS.
This is again inconsistent with the rest of the code, so
was changed to use _test_mount() and instead of checking
if MOUNT_OPTIONS have changed between sections, we check if
TEST_FS_MOUNT_OPTS were changed between sections.
Otherwise, we can leave the test partition mounted.

This change is needed to support overlay base fs mount
and for multi section config files which include overlay FSTYP.

Amir Goldstein 64343ded7d fstests: sanity check that test partitions are not mounted elsewhere
When $TEST_DEV is mounted at a different location then $TEST_DIR,
_require_test() aborts the test with an error:
 TEST_DEV=/dev/sda5 is mounted but not on TEST_DIR=/mnt/test

There are several problems with current sanity check:
1. the output of the error is mixed into out.bad and hard to see
2. the test partition is unmounted at the end of the test regardless
   of the fact that it not pass the sanity that we have exclusivity
3. scratch partition has a similar sanity check in _require_scratch(),
   but we may not get to it, because $SCRATCH_DEV is unmounted prior
   to running the tests (which could unmount another mount point).

To solve all these problems, introduce a helper _check_mounted_on().
It checks if a device is mounted on a given mount point and optionally
checks the mounted fs type.

The sanity checks in _require_scratch() and _require_test() are
converted to use the helper and gain the check for correct fs type.

The helper is used in init_rc() to sanity check both test and scratch
partitions, before tests are run and before $SCRATCH_DEV is unmounted.
