selftests/ftrace: Fix dependencies for some of the synthetic event tests

2023-09-09T03:13:03+00:00

Commit b81a3a100cca1b ("tracing/histogram: Add simple tests for stacktrace usage of synthetic events") changed the output text in tracefs README, but missed updating some of the dependencies specified in selftests. This causes some of the tests to exit as unsupported. Fix this by changing the grep pattern. Since we want these tests to work on older kernels, match only against the common last part of the pattern.

tracing/selftests: Update synthetic event selftest to use common_stacktrace

2023-05-24T03:47:49+00:00

With the rename of the stacktrace field to common_stacktrace, update the selftests to reflect this change. Copy the current selftest to test the backward compatibility "stacktrace" keyword. Also the "requires" of that test was incorrect, so it would never actually ran before. That is fixed now.

tracing/histogram: Add simple tests for stacktrace usage of synthetic events

2023-01-25T15:31:24+00:00

Update the selftests to include a test of passing a stacktrace between the events of a synthetic event.

selftests/ftrace: Use long for synthetic event probe test

2022-12-02T17:53:03+00:00

On 32bit the trigger-synthetic-eprobe.tc selftest fails with the error: hist:syscalls:sys_exit_openat: error: Param type doesn't match synthetic event field type Command: hist:keys=common_pid:filename=$__arg__1,ret=ret:onmatch(syscalls.sys_enter_openat).trace(synth_open,$filename,$ret) ^ This is because the synth_open synthetic event is created with: echo "$SYNTH u64 filename; s64 ret;" > synthetic_events Which works fine on 64 bit, as filename is a pointer and the return is also a long. But for 32 bit architectures, it doesn't work. Use "unsigned long" and "long" instead so that it works for both 64 bit and 32 bit architectures.

selftests/ftrace: Add check for ping command for trigger tests

2022-10-28T08:01:11+00:00

All these tests depend on the ping command and will fail if it is not found. Allow tests to specify dependencies on programs through the 'requires' field. Add dependency on 'ping' for some of the trigger tests.

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.
