[PATCH v2 0/3] CIFS support for XFS test suite

[Pavel Shilovsky]

These are patches that adds CIFS support to XFS tests.

The first patch changes generic/013 test to use mount options provided for $TEST_DEV for remount. The second patch adds "-cifs" command line argument and CIFS specific variables. The third patch disables tests that need POSIX behavior from filesystem for unix cifs mounts.

With these patches applied, most of generic/shared $TEST_DEV tests pass for the recent kernel cifs module.

Pavel Shilovsky (3):
  generic/013: encapsulate remount during cleanup
  common: add cifs support
  cifs: skip tests that need POSIX support for nounix mounts

[PATCH v2 1/3] generic/013: encapsulate remount during cleanup

[Pavel Shilovsky]

The existing code calls remount for $TEST_DEV with constantly defined
mount options. This can fail if a user specifies different mount options.
Fix this by using new _test_remount() call that remounts $TEST_DEV.

Looks technically correct, but I still wonder why it's needed at all,
I can't see anything in the test that would remount the filesystem
read-only.  git history isn't a help here as the remount goes back to
the first public revision.

Anyway I think it won't hurt to apply this patch at first and then probably remove this part at all.

Can you take care of mentioning tmpfs as well, looks like it didn't get
added here when support was added.

Will we ever find a way to sanity check a cifs fs? :)

Otherwise looks fine to me.

Probably some day we will be able to run fsck checks on the remote server through a specific rpc.

[PATCH v2 3/3] cifs: skip tests that need POSIX support for nounix mounts

[Pavel Shilovsky]

CIFS/SMB protocol without POSIX extensions doesn't support operations
with symbolic links and advisory byte-range locks from the same process.
Add a check for nounix mounts and use it in generic tests that
require such operations.

+_require_test_posix_ext seems very cifs specific.  Can you take
a look at the tests and see what posix feature they require and
add features based on that?  Let's have a quick discussion here on the
requirements of the tests before even writing the code.

this suggest 005 needs symlinks and plain cifs doesn't support them.
We should also fold this test for IRIX udf into the _requires_symlink
tests.

023-025 just require a working renameat2, and nothing in Posix.  What's
the problem for cifs here?

131 tests fcntl style file locking, so we should test for that.

Do you know a more standardized way to test if symlink support is available?
We don't really have the same thing as the FS and Device capability ioctls
that Microsoft offers, but even for them, they don't export whether symlink
support is enabled as a volume or export property.
Presumably we could try to create one and look for the rc EOPNOTSUPP), but
it seems simple enough for now to check on mount looking for
fs-specific features
as Pavel has done, or to always enable the symlink tests for cifs (and
smb3 after
we have added it).

Plain cifs does support emulated symlinks two ways but they aren't enabled by
default in mount.  At least one of these also needs to be added to SMB3, and
when I looked at this in the past it looked fairly easy. When support for
"mfsymlinks" (apple-style emulated symlinks) or for creating "NFS-reparse point
symlinks" (Windows style NFS server symlinks)  is added
for SMB3 we could change the way the cifs check is done.  In the long run I
would prefer that we run the cifs and smb3 xfstest runs with symlink
dependent tests enabled.

Agree.

These tests try to create symlinks and then rename them.

So for these tests we need two check functions: _require_symlink for 005, 023, 024, 025 and _require_fcntl for 131. Right?

More or less. I'd call the second one _require_fcntl_locks as fcntl
is a multiplexer for tons of unrelated functionality.

Ok, let's name it this way.

What's about the 1st and 2nd patches? I am going to repost the series
with a new version of the 3rd patch (according to our discussion) and
it'll be better to incorporate their possible changes as well.
