Hi Eryu,
I rebased my branch to your master and made some minor adaptations
to Xiong's new tests. Also reordered the patches:
- patches 1-6 are generic fixes and re-factoring - if you wish,
you can merge them before the overlay config changes.
- patches 7-10 implement the new overlay config. patches 7 and 10
include adaptations of Xiong's new tests to new config.
This is the 5th revision of new overlayfs config.
The main motivation of this work is to help catch overlayfs bugs
related to leaking objects in underlying (base) fs.
With this change, all you have to do to run overlay tests if you
already have a local.config setup to test a local file system is:
./check -overlay
See README.overlay for some examples of config files to use with -overlay.
The legacy overlayfs configuration, where TEST_DEV is a directory
still works, but it should be deprecated.
Tested ./check -overlay -g quick with both legacy overlay configuration
and the new base fs configuration.
Eryu wished to keep these changes soaking on the list for while,
so for those who can help with testing, you can get pull the branch
for testing from my github tree [1].
Thanks,
Amir.

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.

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.

Create helper _canonicalize_mountpoint() to check and canonicalize
a mount point path.
Use helper to canonicalize TEST_DIR and SCRATCH_MNT after parse
of every config section.
This is needed for overlay base fs mount.

When configuring overlay base fs, TEST_DEV/DIR and SCRATCH_DEV/MNT
are derived from the base fs mount points, where *_DEV are the
path of the base fs mount point and TEST_DIR/SCRATCH_MNT are
a directory under the base fs mount point.
This means that the overlay DEV paths are prefixes of the overlay
mount points.
Fix the test and sctach filters to check if TEST_DEV/SCRATCH_DEV is
a substring of TEST_DIR/SCRATCH_MNT and try and match the longer
string first.

When configure SCRATCH_DEV to a mount point (and not to a directory therein)
then user will get a false positive error in scratch tests:
$SCRATCH_DEV=/mnt/base/scratch is mounted but not on $SCRATCH_MNT=/mnt/scratch
Already mounted result:
/dev/sda6 on /mnt/base/scratch type xfs (rw,relatime,attr2,inode64,noquota)
This is due to the wrong `grep -F $SCRATCH_DEV` which matches the mount
point instead of the device in that mount.
Fix _check_mounted_on() to grep the pattern "$dev on " and "$dev on $mnt"
instead of just grepping for "$dev" and "$mnt" without the " on " anchor.

Test is calling _get_block_size $SCRATCH_MNT before
_scratch_mount. This results in block size of the
wrong fs and a failure with overlay base fs setup.

As preparation step for configuring test/scratch base fs
for overlay tests:
- Rename OVERLAY_LOWER/UPPER/WORK_DIR => OVL_LOWER/UPPER/WORK
because we want to use OVL_ prefix for all base fs vars
- 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"

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.

+
+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

+/mnt/test/ovl-mnt and /mnt/scratch/ovl-mnt, for the context of
+individual tests.

To: Eryu Guan; +Cc: Miklos Szeredi, Xiong Zhou, linux-unionfs, fstests
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.

+'./check -overlay' does not support mkfs and fsck on the base fs, so

+An easy way to accomplish this is by running './check <some test>' once,

+
+Because of the lack of mkfs support, multi-section config files are only
+partly supported with './check -overlay'. Only multi-section files that

Use the new var OVL_BASE_SCRATCH_MNT to refer to overlay
base dir instead of the legacy SCRATCH_DEV var.
In overlay/011, when using MOUNT_PROG directly, provide
OVL_BASE_SCRATCH_MNT as device argument instead of 'none'.
This fix is required to support mount of base fs.
