[LTP] "cgroup_fj" and "cgroup" have problems?

[LTP] "cgroup_fj" and "cgroup" have problems?

[Mitani]

Hi,

Sorry for my many many mails today.


I ran tests with "ltp-2009-12-10" cvs.

In my system (kernel 2.6.18-164.el5), kernel does not support 
control groups.
So, when I ran test of "cgroup_fj", I got following message and the
test faild by "FAIL 253".

------------
***error***:you must enable cgroup config in kernel
------------

In the investigation for above error message, I found that there may be
two problems,.

  (a) "cgroup_fj" test failed in the system not support "control groups".
  (b) "cgroup" test may passed by user-ID which isn't "root".


(a) "cgroup_fj" test
  Above message is correct message, but exiting by "FAIL" is not
  correct, I think.
  Referring to the example of other tests, I think that the tests
  for non-supported functions must be finished in "PASS 0" basically.
  (For example, "move_pages{01...11}" tests exit in "PASS 0" and with 
  "NUMA support not provided" messages.)

  I suggest following patch to resolve this problem.

(b) "cgroup" test
  I watched "cgroup" test source for hints for (a), and found another
  problem.
  If this test run by user-ID non-"root", it will exit in "PASS", I think.
  But I think that it must exit in "FAIL".
  Because this test cannot be tested only by "root" user.

1. Case 1 should be tst_brkm TCONF and should have exit 0 (like you suggested).
2. Case 2 should have the equivalent exit code for TBROK (it's in include/test.h). $? -> -1 is undefined via POSIX and while it passes on bash, it doesn't pass on ash, and thus would fail with busybox.
Thanks,

Re: [LTP] "cgroup_fj" and "cgroup" have problems?

[Mitani]

I took your indication and changed the patch as follows.

Case 1:
I revised "[ -f /proc/cgroups ]" case to use "tst_resm TCONF"
instead of "echo".
But this revision is unbalanced with the other exit messages,
so I revised other cases too.
I don't know how to use exit code, so I use 0 or 1.
I might mistake those code.

Re: [LTP] "cgroup_fj" and "cgroup" have problems?

[Mitani]

Hi,

Thank you for fixing "cgroup" and "cgroup_fj".
However, I found a new problem in revised "cgroup" testcases.

It's in "cgroup_regression_test.sh".

In my original patch, I didn't revise about "tst_kvercmp 2 6 29" 
judgment.
But in fixed version, the error route of above judgment revised 
from "TBROK" to "TCONF".
If "TCONF" is used, the shell should end by exit 0, I think.
But "cgroup_regression_test.sh" does not end by exit 0.

Please consider about the following patch:

Re: [LTP] "cgroup_fj" and "cgroup" have problems?

[Mitani]

Hi,

I revised "cgroup_fi" testset and wrote it to mailing-list in 2009.12.14.
  http://www.mail-archive.com/ltp-list@lists.sourceforge.net/msg09000.html

But I received no reply and there is no update in 
"SCM Repositories - ltp".

Please give me some opinion about the patch if you would.
I'm looking forward to your reply.


Regards--

-Tomonori Mitani
