[PATCH v4 0/5] Rework KUnit test execution in modules

by David Gow

This patch series makes two changes to how KUnit test suites are stored and executed: - The .kunit_test_suites section is now used for tests in modules (in lieu of a module_init funciton), as well as for built-in tests. The module loader will now trigger test execution. This frees up the module_init function for other uses. - Instead of storing an array of arrays of suites, have the kunit_test_suite() and kunit_test_suites() macros append to one global (or per-module) list of test suites. This removes a needless layer of indirection, and removes the need to NULL-terminate suite_sets. The upshot of this is that it should now be possible to use the kunit_test_suite() and kunit_test_suites() macros to register test suites even from within modules which otherwise had module_init functions. This was proving to be quite a common issue, resulting in several modules calling into KUnit's private suite execution functions to run their tests (often introducing incompatibilities with the KUnit tooling). This series also fixes the thunderbolt, nitro_enclaves, and sdhci-of-aspeed tests to use kunit_test_suite() now that it works. This is required, as otherwise the first two patches may break these tests entirely. Huge thanks to Jeremy Kerr, who designed and implemented the module loader changes, and to Daniel Latypov for pushing the simplification of the nested arrays in .kunit_test_suites. I've tested this series both with builtin tests on a number of architectures, and with modules on x86_64, and it seems good-to-go to me. More testing (particularly of modules) with more interesting setups never hurts, though! Cheers, -- David Changes since v3: https://lore.kernel.org/linux-kselftest/20220625050838.1618469-1-davidgow@g… - Rebase on top of the TAINT_TEST patch series.

[PATCH] module: kunit: Load .kunit_test_suites section when CONFIG_KUNIT=m

by David Gow

The new KUnit module handling has KUnit test suites listed in a .kunit_test_suites section of each module. This should be loaded when the module is, but at the moment this only happens if KUnit is built-in. Also load this when KUnit is enabled as a module: it'll not be usable unless KUnit is loaded, but such modules are likely to depend on KUnit anyway, so it's unlikely to ever be loaded needlessly.

[PATCH AUTOSEL 5.10 15/46] selftests: mlxsw: resource_scale: Allow skipping a test

by Sasha Levin

From: Petr Machata <petrm(a)nvidia.com> [ Upstream commit 8cad339db339a39cb82b1188e4be4070a433abac ] The scale tests are currently testing two things: that some number of instances of a given resource can actually be created; and that when an attempt is made to create more than the supported amount, the failures are noted and handled gracefully. Sometimes the scale test depends on more than one resource. In particular, a following patch will add a RIF counter scale test, which depends on the number of RIF counters that can be bound, and also on the number of RIFs that can be created. When the test is limited by the auxiliary resource and not by the primary one, there's no point trying to run the overflow test, because it would be testing exhaustion of the wrong resource. To support this use case, when the $test_get_target yields 0, skip the test instead.
