Subject: [PATCH v9 8/9] selftests/livepatch: Add state test for provides/obsoletes
Date: Sun, 13 Sep 2026 10:42:27 +0800 [thread overview]
Message-ID: <20260913024228.72317-9-laoar.shao@gmail.com> (raw)
In-Reply-To: <20260913024228.72317-1-laoar.shao@gmail.com>
Livepatches with different provides ids must not share the same state
id, unless the second livepatch replaces the first one via obsoletes.
Add provides/obsoletes module parameters to test_klp_state and
test_klp_state2, and cover both cases: reusing a state id across
different provides ids is rejected, while it is allowed when the new
livepatch obsoletes the old one.
Suggested-by: Petr Mladek <pmladek@suse.com>
