selftests/ftrace: fix dynamic_events dependency check

2022-10-18T20:27:23+00:00

commit 95c104c378dc ("tracing: Auto generate event name when creating a group of events") changed the syntax in the ftrace README file which is used by the selftests to check what features are support. Adjust the string to make test_duplicates.tc and trigger-synthetic-eprobe.tc work again.

selftests/ftrace: Add selftest for testing eprobe events on synthetic events

2021-08-21T14:25:34+00:00

Add a test to test event probes, by creating a synthetic event across sys_enter_openat and sys_exit_openat that passes the filename pointer from the enter of the system call to the exit, and then add an event probe to the synthetic event to make sure that the file name is seen.

tracing/selftests: Add tests to test histogram sym and sym-offset modifiers

2021-07-08T17:01:51+00:00

Add a test to the tracing selftests that will catch if the .sym or .sym-offset modifiers break in the future. Link: https://lkml.kernel.org/r/20210707121451.101a1002@oasis.local.home Acked-by: Tom Zanussi Acked-by: Masami Hiramatsu Signed-off-by: Steven Rostedt (VMware)

selftests/ftrace: Add '!event' synthetic event syntax check

2021-02-11T21:22:32+00:00

Add a check confirming that '!event' alone will remove a synthetic event. Link: https://lkml.kernel.org/r/1dff3f03d18542cece08c10d6323d8a8dba11e42.1612208610.git.zanussi@kernel.org Signed-off-by: Tom Zanussi Signed-off-by: Steven Rostedt (VMware)

selftests/ftrace: Update synthetic event syntax errors

2021-02-11T21:22:20+00:00

Some of the synthetic event errors and positions have changed in the code - update those and add several more tests. Also add a runtime check to ensure that the kernel supports dynamic strings in synthetic events, which these tests require.

selftests/ftrace: Add test case for synthetic event syntax errors

2020-10-15T16:01:13+00:00

Add a selftest that verifies that the syntax error messages and caret positions are correct for most of the possible synthetic event syntax error cases.

selftests/ftrace: Change synthetic event name for inter-event-combined test

2020-10-15T16:01:13+00:00

This test uses waking+wakeup_latency as an event name, which doesn't make sense since it includes an operator. Illegal names are now detected by the synthetic event command parsing, which causes this test to fail. Change the name to 'waking_plus_wakeup_latency' to prevent this.

selftests/ftrace: Add test case for synthetic event dynamic strings

2020-10-08T19:28:41+00:00

Add a selftest that defines and traces a synthetic event that uses a dynamic string event field. Link: https://lkml.kernel.org/r/74445afb005046d76d59fb06696a2ceaa164dec9.1601848695.git.zanussi@kernel.org Acked-by: Masami Hiramatsu Signed-off-by: Tom Zanussi Signed-off-by: Steven Rostedt (VMware)

selftests/ftrace: Support ":README" suffix for requires

2020-06-16T16:42:47+00:00

Add ":README" suffix support for the requires list, so that the testcase can list up the required string for README file to the requires list. Note that the required string is treated as a fixed string, instead of regular expression. Also, the testcase can specify a string containing spaces with quotes.
