[PATCH v3 0/9] drm: selftest: Convert to KUnit

by Maíra Canal

Hi everyone, Here is the v3 of the conversion of selftests to KUnit. Since the v2, there have been minor fixes. drm_format_test received the biggest change: the KUNIT_EXPECT_FALSE and KUNIT_EXPECT_TRUE macros were changed to KUNIT_EXPECT_EQ, as suggested by Daniel. Most of all, the patches were rebased on top of the recently applied patches for drm_format_helper tests (8f456104915f), in order to avoid conflicts when applying the tests. Thanks for your attention and any feedback is welcomed! Best Regards, - Maíra Canal v1 -> v2: https://lore.kernel.org/dri-devel/20220615135824.15522-1-maira.canal@usp.br… - The suites not longer end in _tests (David Gow). - Remove the TODO entry involving the conversion of selftests to KUnit (Javier Martinez Canillas). - Change the filenames to match the documentation: use *_test.c (Javier Martinez Canillas). - Add MODULE_LICENSE to all tests (kernel test robot). - Make use of a generic symbol to group all tests - DRM_KUNIT_TEST (Javier Martinez Canillas). - Add .kunitconfig on the first patch (it was on the second patch of the series). - Straightforward conversion of the drm_cmdline_parser tests without functional changes (Shuah Khan). - Add David's Tested-by tags. v2 -> v3: https://lore.kernel.org/dri-devel/20220621200926.257002-1-maira.canal@usp.b… - Rebase it on top of the drm-misc-next with drm_format_helper KUnit tests. - Change KUNIT_EXPECT_FALSE to KUNIT_EXPECT_EQ on drm_format_test (Daniel Latypov). - Add Daniel's Acked-by tag.

[PATCH v4 1/4] panic: Taint kernel if tests are run

by David Gow

Most in-kernel tests (such as KUnit tests) are not supposed to run on production systems: they may do deliberately illegal things to trigger errors, and have security implications (for example, KUnit assertions will often deliberately leak kernel addresses). Add a new taint type, TAINT_TEST to signal that a test has been run. This will be printed as 'N' (originally for kuNit, as every other sensible letter was taken.) This should discourage people from running these tests on production systems, and to make it easier to tell if tests have been run accidentally (by loading the wrong configuration, etc.) Acked-by: Luis Chamberlain <mcgrof(a)kernel.org> Reviewed-by: Brendan Higgins <brendanhiggins(a)google.com> Signed-off-by: David Gow <davidgow(a)google.com> --- Finally getting back to this, with the addition of a MODULE_INFO() to mark a module as a test module. This is automatically set for modules in the "tools/testing" directory by modpost (see patch #2). The 'N' character for the taint is even less useful now that it's no longer short for kuNit, but all the letters in TEST are taken. :-( Changes since v3: https://lore.kernel.org/lkml/20220513083212.3537869-1-davidgow@google.com/ - Remove the mention of KUnit from the documentation. - Add Luis and Brendan's Acked/Reviewed-by tags. Changes since v2: https://lore.kernel.org/linux-kselftest/20220430030019.803481-1-davidgow@go… - Rename TAINT_KUNIT -> TAINT_TEST. - Split into separate patches for adding the taint, and triggering it. - Taint on a kselftest_module being loaded (patch 3/3) Changes since v1: https://lore.kernel.org/linux-kselftest/20220429043913.626647-1-davidgow@go… - Make the taint per-module, to handle the case when tests are in (longer lasting) modules.

remove CONFIG_ANDROID

by Christoph Hellwig

Hi Greg, this series removes the CONFIG_ANDROID. It just guards the Kconfig option for binder and then changes a bunch of random defaults and settings, which makes no sense whatsoever and none of those changes had any good justifcation in their commit logs either.
