Dear All,
The Linux Test Project test suite has been released for the month of
APRIL 2008. The latest version of the test-suite contains 3000+ tests
for the Linux OS and can be found at
http://ltp.sourceforge.net/.
Latest happenings in LTP can also be found at:
http://ltp.sourceforge.net/wiki/,
http://ltp.sourceforge.net/wikiArchives.php, and,
IRC: irc.freenode.org #ltp.
APRIL 2008 Highlights:
* Release of LTP Development RPMs enabling Kernel developers to create
standalone LTP unit test case(s),
* Addition of Initial set of MEMORY CONTROLLER test cases,
* Cleanups for existing CPU CONTROLLER test cases,
* Continuing work for Concurrency fixes,
* Cleanup/Updates to LTP Real Time test cases,
* Cleanup/Updates to LTP SELinux test cases,
* SGI Common Criteria CAPP/LSPP EAL4+ certification test suite Release,
* Release of gcov-kernel patches for Linux 2.6.25,
* A Paper on LTP´s progress has been submitted to OLS 2008 committee.
Note(s) from the Maintainer:
Kerlabs kept the wheel rolling for fixing the concurrency issues. RT
tree cleanup and updates has become very common. Hope this brings good
news to the RT Linux community and users. The SELinux community has kept
their LTP test cases up-to-date. SGI has chosen LTP to release their
common criteria certification testsuite. And as promised earlier, we
brought in the initial set of MEMORY controller tests to LTP with
cleanups for the existing CPU controller test cases. But equally
disappointing to see that new test cases from others in the community
are not flowing into LTP. The maintainer has worked to put forward a
Paper on LTP´s progress in OLS 2008. Hope this will generate enthusiasm
among other members of the community.
I would reiterate my request to engineers across Linux Distros to kindly
consider integrating the enhancements/fixes they might have done to
their local LTP suit to the Global LTP Project.
Our web site also contains other information such as:
- A Linux test tools matrix
- Technical papers
- How To's on Linux testing
- Code coverage analysis tool.
We would encourage the community to post results to
[EMAIL PROTECTED],
patches, new tests, bugs or comments/questions to [EMAIL PROTECTED],

This patch should solve the problem of RT Linux Compilation Failure on various

the x86 and ppc. Signed-Off-By: Chirag <[EMAIL PROTECTED]>

Previously I was under the impression that selinux test was not cleaning up
properly. I don't believe that to be the case. I must have been mistaken. Here
is a patch for the allow_domain_fd_use boolean issue in 5.2, by, Jeff Burke
<[EMAIL PROTECTED]>
Modified File(s):
ltp/testscripts/test_selinux.sh
4) Log Message:
This patch, which is independent of Jeff's patch, updates the selinux testsuite
to run under Fedora 9, and does no harm on Fedora 8. While creating this, I
noticed two other things that ultimately need fixing:
1) The sbin_deprecated.patch adds domain_dyntrans_type() to all the test
domains. If that was truly desired, we should just put it into
unconfined_runs_test(). But it shouldn't be necessary - only the
test_dyntrans.te and test_dyntrace.te domains should require permissions for
dynamic transitions. I'll let Serge confirm that.
2) The test scripts are presently relabeling /tmp to test_file_t for the
duration of the test. That's insane - it could break any other running process
that tries to access /tmp during the test. That was not part of our original
selinux testsuite and seems to have been introduced when IBM ported it to LTP.
If you are worried about lacking search permission to /tmp in the test domains,
then create your own private /test directory or something. Or just give all
test domains permission to search tmp either via unconfined_runs_test() or in
test_global.te using the testdomain attribute. Those don't need to be fixed
though for this patch to be merged. Also, I noticed some new failures in the
tests due to latest Fedora policies giving all domains search permission to all
directories. Not sure if that was intentional - sent a separate note to Dan
about that.

5) Log Message:
Ok here is a first small patch to stop relabeling /tmp as Stephen suggested. It
should be no more complicated to get rid of the unneeded dyntrans_types, but I
messed up somewhere generating the patch and subsequent test bombed. So I'll
just do that next week or whenever this patch hits cvs (for simplicity).
Subject: selinux testsuite: don't relabel /tmp. There's no need for the selinux
testsuite to relabel /tmp for the duration of the test. It uses /tmp/selinux
anyway. Just need to be sure to have search perms to tmp_t. Signed-off-by:

RETURN VALUE
If name is invalid, -1 is returned, and errno is set to EINVAL.
Otherwise, the value returned is the value of the system resource and errno is
not changed. In the case of options, a positive value is returned if a
queried option is available, and -1 if it is not. In the case of limits, -1
means that there is no definite limit
***********
Return value of sysconf needs to be checked as well and not only depend on
errno value. Have made the changes by looking at the code from

This turned out to be a test case problem, where it fails to identify the

'IFNAME=eth1 ./tcpdump01' it will pass. But it relies on DNS lookup and

where Jeff Burke raise this problem with f00f failing on systems that have the
NX bit. But, according to the flags reported in /proc/cpuinfo, the machines
where i'm running this testcase seems not to have this NX bit enabled. On
/proc/cpuinfo, we also have this line "f00f_bug: no". Would it be useful to
select if this testcase should be executed or not? These machines are running a
kernel compiled with processor family "Pentium-Pro" (CONFIG_M686=y), which, in

Attached is a patch to ltp/lib/Makefile that fixes Solaris cross-building. For
some reason the variable CC was overridden with gcc -Wall which caused it to

56) Log Message:
The float_bessel testcases, as a matter of fact, all float_* testcases seem to
fail when multiple instances are run concurrently. The failures occur because
file sizes don't match or because the number of bytes read don't match the file
size. This can be attributed to the parallel instance reading a file before the
write to it (by another instance) has completed. In such situations, either the
file size has not been updated in the inode header or the file size has been
updated but the file's write operation has not been updated completely. To fix
this concurrency problem, my suggestion is to check for an existing instance
and wait for it to finish before beginning the current instance. Any other
concurrency resolution technique may complicate matters. A message to the
console indicating such a decision might be added. By Sridhar Vinay <[EMAIL
PROTECTED]> & Renaud Lottiaux <[EMAIL PROTECTED]>.
