selftests/tracing: Allow some more tests to run in instances

2025-02-20T20:15:14+00:00

The tests: trigger-action-hist-xfail.tc trigger-onchange-action-hist.tc trigger-snapshot-action-hist.tc trigger-hist-expressions.tc can all run in an instance. Test them in an instance as well.

selftests/ftrace: Clean up triggers after setting them

2025-02-20T20:15:07+00:00

The triggers set in trigger-onchange-action-hist.tc and trigger-snapshot-action-hist.tc are not cleaned up at the end. These tests can also be done in instances and without cleaning up the triggers, the instances can not be removed as they are still "busy".

selftests/tracing: Add hist poll() support test

2025-01-07T16:48:07+00:00

Add a testcase for poll() on hist file. This introduces a helper binary to the ftracetest, because there is no good way to reliably execute poll() on hist file.

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.

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.
