2014-11-03ftracetest: Sort testcasesHeiko Carstens1-1/+1
Make sure the order of the executed testcases is always the same.

2014-11-03ftracetest: Add kprobes on ftrace testcaseHeiko Carstens1-0/+55
Add a kprobes on ftrace testcase. The testcase verifies that - enabling and disabling function tracing works on a function which already contains a dynamic kprobe - adding and removing a dynamic kprobe works on a function which is already enabled for function tracing Link: http://lkml.kernel.org/p/1413802323-5297-2-git-send-email-heiko.carstens@de.ibm.com Acked-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2014-11-03ftracetest: Take the first debugfs mount foundSteven Rostedt (Red Hat)1-1/+1
Running ftracetests on a box that mounted debugfs in two locations made the ftracetests fail. This is because the tests uses a grep of debugfs from the /proc/mounts file to find the debugfs mount point, and then appends "/tracing" to that string to get the tracing directory. If the debugfs directory is mounted twice, then that grep will return two answers and appending "/tracing" to a string with two lines will not work. Use "head -1" to only take the first mount point found. Acked-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2014-10-08tracing/kprobes: Add selftest scripts testing kprobe-tracer as startup testMasami Hiramatsu2-0/+31
Add two selftest scripts which tests kprobe-tracer as the startup selftest does. These test cases are testing that the kprobe_event can accept a kprobe event with $stack related arguments and a kretprobe event with $retval argument.

2014-10-03ftracetest: Add POSIX.3 standard and XFAIL result codesMasami Hiramatsu13-33/+189
Add XFAIL and POSIX 1003.3 standard codes (UNRESOLVED/ UNTESTED/UNSUPPORTED) as result codes. These are used for the results that test case is expected to fail or unsupported feature (by config). To return these result code, this introduces exit_unresolved, exit_untested, exit_unsupported and exit_xfail functions, which use real-time signals to notify the result code to ftracetest. This also set "errexit" option for the testcases, so that the tests don't need to exit explicitly. Note that if the test returns UNRESOLVED/UNSUPPORTED/FAIL, its test log including executed commands is shown on console and main logfile as below. ------ # ./ftracetest samples/ === Ftrace unit tests === [1] failure-case example [FAIL] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/fail.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/fail.tc ++ cat non-exist-file cat: non-exist-file: No such file or directory [2] pass-case example [PASS] [3] unresolved-case example [UNRESOLVED] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unresolved.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unresolved.tc ++ trap exit_unresolved INT ++ kill -INT 29324 +++ exit_unresolved +++ kill -s 38 29265 +++ exit 0 [4] unsupported-case example [UNSUPPORTED] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unsupported.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unsupported.tc ++ exit_unsupported ++ kill -s 40 29265 ++ exit 0 [5] untested-case example [UNTESTED] [6] xfail-case example [XFAIL] # of passed: 1 # of failed: 1 # of unresolved: 1 # of untested: 1 # of unsupported: 1 # of xfailed: 1 # of undefined(test bug): 0 ------ Link: http://lkml.kernel.org/p/20140929120211.30203.99510.stgit@kbuild-f20.novalocal Acked-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2014-09-23ftracetest: Add kprobe basic testcasesMasami Hiramatsu2-0/+25
Add basic testcases for kprobe dynamic events. This also shows that the ftracetest accepts sub-directory for new testcases.

Add ftrace basic testcases. This just checks ftrace debugfs interface works as it is designed.

2014-09-23ftracetest: Initial commit for ftracetestMasami Hiramatsu4-0/+215
ftracetest is a collection of testcase shell-scripts for ftrace. To avoid regressions of ftrace, these testcases check correct ftrace behaviors. If someone would like to add any features on ftrace, the patch series should have at least one testcase for checking the new behavior.
