selftests/livepatch: Don't clear dmesg when running tests

2020-06-19T08:46:42+00:00

Inspired by commit f131d9edc29d ("selftests/lkdtm: Don't clear dmesg when running tests"), keep a reference dmesg copy when beginning each test. This way check_result() can compare against the initial copy rather than relying upon an empty log.

selftests/livepatch: simplify test-klp-callbacks busy target tests

2020-06-08T08:36:10+00:00

The test-klp-callbacks script includes a few tests which rely on kernel task timings that may not always execute as expected under system load. These may generate out of sequence kernel log messages that result in test failure. Instead of using sleep timing windows to orchestrate these tests, add a block_transition module parameter to communicate the test purpose and utilize flush_queue() to serialize the test module's task output.

selftests/livepatch: Make dynamic debug setup and restore generic

2019-11-04T14:33:15+00:00

Livepatch selftests currently save the current dynamic debug config and tweak it for the selftests. The config is restored at the end. Make the infrastructure generic, so that more variables can be saved and restored.

selftests/livepatch: introduce tests

2019-01-11T19:51:24+00:00

Add a few livepatch modules and simple target modules that the included regression suite can run tests against: - basic livepatching (multiple patches, atomic replace) - pre/post (un)patch callbacks - shadow variable API Signed-off-by: Joe Lawrence Signed-off-by: Petr Mladek Tested-by: Miroslav Benes Tested-by: Alice Ferrazzi Acked-by: Joe Lawrence Acked-by: Josh Poimboeuf Signed-off-by: Jiri Kosina
