Subject: [for-next][PATCH 06/16] rtla/tests: Extend action tests to 5s
Date: Thu, 20 Nov 2025 18:23:29 -0500 [thread overview]
Message-ID: <20251120232708.273880490@kernel.org> (raw)
In-Reply-To: 20251120232323.271532418@kernel.org
From: Tomas Glozar <tglozar@redhat.com>
In non-BPF mode, it takes up to 1 second for RTLA to notice that tracing
has been stopped. That means that action tests cannot have a 1 second
duration, as the SIGALRM will be racing with the threshold overflow.
Previously, non-BPF mode actions were buggy and always executed
the action, even when stopping on duration or SIGINT, preventing
this issue from manifesting. Now that this has been fixed, the tests
have become flaky, and this has to be adjusted.
Fixes: 4e26f84abfb ("rtla/tests: Add tests for actions")
Fixes: 05b7e10687c ("tools/rtla: Add remaining support for osnoise actions")
