Hi,
I went through in doing testing around couple of machines and here are
my observations. First of all i would like it to get it integrated with
LTP-build, which your patch presently does not provide. In next
iteration you can include this patch:
ProcessEventConnectorBuildDefault.patch
Process Event Connector was added from 2.6.15 onwards(Correct me if i am
wrong). So, i can see that the tests did not build for kernels below
2.6.15 (for all architectures i tested, it failed when kernel is below
2.6.15). Even for kernels above 2.6.15, it failed for ia64
(kernel=2.6.16.21-0.8-default). Even though the test built successfully
for ppc64 and ia64(kernel > 2.6.15), the test-run failed for both.
Please see the following table for the summary and later for detailed
output:
===========================================================
||Architecture||Kernel||Build||Run||
===========================================================
||i386||2.6.18-53.1.13.el5||PASSED||PASS(root),FAIL(non-root)||
||x86_64||2.6.9-67.ELsmp||FAILED||
||x86_64||2.6.18-92.el5||PASSED||PASSED as root-user||
||ppc64||2.6.9-67.ELsmp||FAILED||
||ppc64||2.6.20-CBE||PASSED||FAILED||
||ia64||2.6.16.21-0.8-default||FAILED||
||ia64||2.6.23.13||PASSED||FAILED||
===========================================================
Also it seems that the tests should be executed as root. Please document
them in your README file.
So, we have 2 potential problem to solve:
1) Prevent building in machines where it is not supported (Criteria can
be i)kernel 2.6.15 below, ii) Some #define criteria). Please see how
this is handled in containers test cases:
http://ltp.cvs.sourceforge.net/ltp/ltp/testcases/kernel/containers/,
http://ltp.cvs.sourceforge.net/ltp/ltp/testcases/kernel/containers/Makefile,
http://ltp.cvs.sourceforge.net/ltp/ltp/testcases/kernel/containers/check_for_unshare.c,
2) Even if you go ahead and build successfully from the Makefile, you
can prevent execution through the usage of tst_kvercmp(int r1, int r2,
int r3) function defined here:
http://ltp.cvs.sourceforge.net/ltp/ltp/lib/tst_kvercmp.c
and used here:
http://ltp.cvs.sourceforge.net/ltp/ltp/testcases/kernel/syscalls/remap_file_pages/remap_file_pages01.c,
I hope this will help you in re-writing this patch and send it across.
When everything goes fine, i will include it and also will generate a
code coverage for the same. Thanks for contributing to LTP. I also found
a test program written by Matt:
