ftracetest: Clear trace buffer after running kprobe testcases

2014-11-06T13:39:39+00:00

The kprobe testcases create, use and delete dynamic events during the test but didn't clear the trace buffer so it'll leave the result after it finishes. # ./ftracetest ... # cat trace # tracer: nop # # entries-in-buffer/entries-written: 2/2 #P:12 # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / delay # TASK-PID CPU# |||| TIMESTAMP FUNCTION # | | | |||| | | ftracetest-26474 [009] d..1 79417.143782: Unknown type 1099 ftracetest-26498 [009] d..1 79417.208034: Unknown type 1101 Link: http://lkml.kernel.org/r/1415239470-28705-2-git-send-email-namhyung@kernel.org Acked-by: Masami Hiramatsu Signed-off-by: Namhyung Kim Signed-off-by: Steven Rostedt

ftracetest: Add kprobes on ftrace testcase

2014-11-03T19:15:46+00:00

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 Signed-off-by: Heiko Carstens Signed-off-by: Steven Rostedt

tracing/kprobes: Add selftest scripts testing kprobe-tracer as startup test

2014-10-08T15:21:46+00:00

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.

ftracetest: Add POSIX.3 standard and XFAIL result codes

2014-10-03T20:44:02+00:00

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 Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt

ftracetest: Add kprobe basic testcases

2014-09-23T13:32:27+00:00

Add basic testcases for kprobe dynamic events. This also shows that the ftracetest accepts sub-directory for new testcases. Link: http://lkml.kernel.org/p/20140922234254.23415.46964.stgit@kbuild-f20.novalocal Acked-by: Namhyung Kim Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt
