[LTP] [PATCH 0/9] shell: nfs: $TST_ALL_FILESYSTEMS (.all_filesystems)

[LTP] [PATCH 0/9] shell: nfs: $TST_ALL_FILESYSTEMS (.all_filesystems)

[Petr Vorel]

Hi,

this is quite ready $TST_ALL_FILESYSTEMS (i.e. support for LTP shell API
to run test on all available filesystems, equivalent of .all_filesystems
in C API). It's used in NFS tests, where I have questions (RFC).

As it uses testcases/lib/tst_supported_fs.c binary it supports the same
features as C API:
* detect supported filesystems
* run only on single filesystem with $LTP_SINGLE_FS_TYPE (debugging)

825e10a91 ("Skip tmpfs in all-filesystem shell tests")


TODO API:
* filtering filesystems when test does not run on certain filesystem
* (i.e. nfs01.sh on vfat) with $TST_SKIP_FILESYSTEMS (equivalent of
  skip_filesystems variable in C API)
* testcases/lib/tst_supported_fs.c skips tmpfs by default since
  825e10a91 ("Skip tmpfs in all-filesystem shell tests"). After
  implementing $TST_SKIP_FILESYSTEMS it could be removed.

TODO NFS tests:
* Do not require restart NFS server (otherwise legacy testcases/lib/daemonlib.sh
  would have to be used)

Comments are welcome.

Code is also at: https://github.com/pevik/ltp/tree/shell/all_filesystems.v2

Kind regards,
Petr

[LTP] [PATCH v2 3/9] tst_test.sh: allow ' in pattern for allowed variables

[Petr Vorel]

to allow using '... $TST_FOO'

i.e. without filtering '
EXPECT_PASS "grep '$TST_MNTPOINT $TST_FS_TYPE' /proc/mounts"
would produce warning:
tst_mount_device 1 TWARN: Reserved variable TST_FS_TYPE' used!
because sed filters it as: FS_TYPE'

Will be needed for next commit.

FYI merged up to this patch, the rest (the actual $TST_ALL_FILESYSTEMS)
will go in v3.

Generally the code looks good, there is still a minor difference between
C API and this changes though. As we do call the _tst_cleanup_timer at
the end of this function the script runs without a timeout for a short
while (which includes tst_mkfs call).

I guess that instead of stopping the timer at the end of the
_tst_run_iterations() we can simply reset it (on the top of this patch):

Re: [LTP] [PATCH v2 5/9] tst_test.sh: Add $TST_ALL_FILESYSTEMS

[Petr Vorel]

Hi Cyril,

Good catch, thanks for providing a patch.
LGTM, I'll have a deeper look later.

Kind regards,

Re: [LTP] [PATCH v2 5/9] tst_test.sh: Add $TST_ALL_FILESYSTEMS

[Petr Vorel]

Hi all,

I wonder if we want to sort filesystems:

-for _tst_fs in $(tst_supported_fs); do
+for _tst_fs in $(tst_supported_fs | sort); do

or even -u (as uniq).

Martin used it in testcases/misc/lvm/prepare_lvm.sh, but IMHO it should not be
needed: looping over fs_type_whitelist() should be always the same.

FS_LIST=`tst_supported_fs | sort -u`

Therefore I'd remove it (don't use unnecessary dependencies - be nice for people
with minimal environment):

Kind regards,
Petr

[LTP] [PATCH v2 7/9] tst_device: Add clear command

[Petr Vorel]

clearing block device will be needed for TST_ALL_FILESYSTEMS
implementation in shell API. Now we clear device during acquire,
but we will reuse this device for each tested filesystem, thus we need a
separate command for it.

[LTP] [RFC][PATCH v2 9/9] nfs: Use TST_ALL_FILESYSTEMS=1

[Petr Vorel]

Signed-off-by: Petr Vorel <pvorel@suse.cz>
---
Hi NFS developers,

your comments are welcome. This is an effort how to support NFS tests on
all filesystems available on SUT. Using $TST_MNTPOINT means test run in
loop, each time different filesystem is used. It's implemented via
formatted loop device (the same way as in LTP C API).

Code is also at: https://github.com/pevik/ltp/tree/shell/all_filesystems.v2

But this requires restarting NFS server (otherwise legacy testcases/lib/daemonlib.sh
would have to be used), which is IMHO not optimal.

Without that (or only run 'systemctl reload nfs-server' or exportfs -r
on remote side) it cannot be umounted after testing - debugging with
fuser, code at:
https://github.com/pevik/ltp/commit/3656d035d43445a107154ef397ef1db2fad2c4f0

The problem is that loop device is still referenced by nfs server and
thus cannot be unmounted. Can this be somehow fixed? Is it even wanted
to have tests on loop device (the only reasonable way to support more
filesystems)? Also tests will run much longer (we could filter out some
filesystems not supported, if there are any).

Maybe try with `umount -fl`?

unmount manual says:
   -f, --force    force unmount (in case of an unreachable NFS system)
   -l, --lazy      detach the filesystem now, clean up things later

> Maybe try with `umount -fl`?

Thank you! Unfortunately it does not work (I tried this before ending up with
restarting server because even -fl did not help).

I also consider the need of 'umount -fl' as kind of error just less aggressive
then restarting server. But if this is considered ok, why not.

Kind regards,
Petr

Hi!

I wonder do we stil have to care for systems without systemd?

We do have daemonlib.sh in LTP that has restart_daemon() function that
branches to systemctl|service|/etc/init.d/ that is used by a few tests.

Hi all,

> I wonder do we stil have to care for systems without systemd?
That'd be a question for embedded people. I myself wonder if they all moved to
systemd. But at least Alpine and Buildroot distros allow to use Busybox as init,
thus I'd still care.

That's exactly what I'm planning to use.

Kind regards,
Petr
