I tried "hugemmap", "hugeshmat", "hugeshmctl", "hugeshmdt" and
"hugeshmget" tests.
And I found several fails in them:
------------<at "${LTPROOT}/testcases/kernel/mem/hugetlb/" directory>
- ./hugemmap/
1) hugemmap04 : return code = 2
- ./hugeshmat/
2) hugeshmat01 : return code = 6
3) hugeshmat02 : return code = 6
4) hugeshmat03 : return code = 2
- ./hugeshmctl/
5) hugeshmctl01 : return code = 6
6) hugeshmctl02 : return code = 6
7) hugeshmctl03 : return code = 2
- ./hugeshmdt/
8) hugeshmdt01 : return code = 6
- ./hugeshmget/
9) hugeshmget01 : return code = 2
10) hugeshmget02 : return code = 6
11) hugeshmget03 : return code = 6
12) hugeshmget05 : return code = 2
------------
These tests output following messages:
------------
a) All tests:
"TBROK : Test cannot be continued owning to sufficient availability of
Hugepages on the system"
b) 2), 3), 5), 6), 8), 10), 11) tests:
"TWARN : tst_rmdir(): TESTDIR was NULL; no removal attempted"
------------
Both case a) and case b) are caused by the same reason.
All of case a) failures occured at the following points (for example
hugemmap04):
------------<hugemmap04.c - main()>
/* Check number of hugepages */
if (get_no_of_hugepages() <= 0 || hugepages_size() <= 0)
tst_brkm(TBROK, cleanup, "Test cannot be continued owning to
\
sufficient availability of Hugepages on the
system");
------------
I found out that "HugePages_Total" parameter of "/proc/meminfo" file
is set to "0". This caused above TBROK failure. It is environment problem.
But, in this case, tests must not return with TBROK, but with TCONF,
I think.
And, in case b), these tests try to delete "TESTDIR" directory by
calling "tst_rmdir()" function in "cleanup()" function.
But, "TESTDIR" never set if "tst_tmpdir()" function isn't called.
I think that case b)'s tests must not call cleanup() function.
I want to suggest following patch.
