selftests: ftrace: Add a testcase for probepoint

2018-05-30T05:49:06+00:00

[ Upstream commit dfa453bc90eca0febff33c8d292a656e53702158 ] Add a testcase for probe point definition. This tests symbol, address and symbol+offset syntax. The offset must be positive and smaller than UINT_MAX.

selftests: ftrace: Add a testcase for string type with kprobe_event

2018-05-30T05:49:06+00:00

[ Upstream commit 5fbdbed797b6d12d043a5121fdbc8d8b49d10e80 ] Add a testcase for string type with kprobe event. This tests good/bad syntax combinations and also the traced data is correct in several way.

selftests: ftrace: Add probe event argument syntax testcase

2018-05-30T05:49:05+00:00

[ Upstream commit 871bef2000968c312a4000b2f56d370dcedbc93c ] Add a testcase for probe event argument syntax which ensures the kprobe_events interface correctly parses given event arguments.

selftests: kprobe: Choose an always-defined function to probe

2015-11-03T23:54:51+00:00

do_fork() is no longer defined on x86, so probe _do_fork() instead. Fixes: 3033f14ab78c ("clone: support passing tls argument via C ...") Signed-off-by: Ben Hutchings Signed-off-by: Shuah Khan

selftests: change install command to rsync

2015-09-14T22:43:51+00:00

The command of install could not handle the special files in exec testcases, change the default rule to rsync to fix this. The installation is unchanged after this commit. Suggested-by: Michael Ellerman Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

selftests/ftrace: install test.d

2015-05-26T21:58:06+00:00

The ftrace test requires the directory test.d and all of it's contents to be present during execution. Use TEST_DIRS to ensure this is copied to the INSTALL_PATH. Acked-by: Michael Ellerman Signed-off-by: Tyler Baker Signed-off-by: Shuah Khan

ftracetest: Do not use usleep directly

2015-04-03T15:16:32+00:00

The usleep is only provided on distros from Redhat so running ftracetest on other distro resulted in failures due to the missing usleep. The reason of using [u]sleep in the test was to generate (scheduler) events. It can be done various ways like this: yield() { ping localhost -c 1 || sleep .001 || usleep 1 || sleep 1; } For more information to the history of this patch, please refer to: Link: http://lkml.kernel.org/r/1427329943-16896-1-git-send-email-namhyung@kernel.org Reported-by: Michael Ellerman Reported-by: Dave Jones Reported-by: Luis Henriques Suggested-by: Pádraig Brady Acked-by: Steven Rostedt Acked-by: Masami Hiramatsu Signed-off-by: Namhyung Kim Signed-off-by: Shuah Khan

ftracetest: Convert exit -1 to exit $FAIL

2015-03-31T16:15:46+00:00

POSIX says that exit takes an unsigned integer between 0 and 255, so using -1 doesn't work on POSIX shells. There is already a well-defined failure code, $FAIL (1), so use that. Signed-off-by: Michael Ellerman Acked-by: Steven Rostedt Signed-off-by: Shuah Khan

ftracetest: Cope properly with stack tracer not being enabled

2015-03-31T16:15:36+00:00

If the stack tracer (CONFIG_STACK_TRACER) is disabled, the fgraph-filter-stack test blows chunks: [8] ftrace - function graph filters with stack tracer [FAIL] + reset_tracer + echo nop ./ftracetest: 19: /home/michael/selftests/ftrace/test.d/ftrace/fgraph-filter-stack.tc: cannot create /proc/sys/kernel/stack_tracer_enabled: Directory nonexistent Fix it by checking if the proc file exists before echoing to it. With the patch applied it fails correctly with: [8] ftrace - function graph filters with stack tracer [UNSUPPORTED] Signed-off-by: Michael Ellerman Acked-by: Steven Rostedt Signed-off-by: Shuah Khan

selftests: Introduce minimal shared logic for running tests

2015-03-13T21:13:40+00:00

This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.
