3f292517 - lib/prime_numbers: KUnit test should not select PRIME_NUMBERS

Mon, 14 Apr 2025 14:35:00 +0000

lib/prime_numbers: KUnit test should not select PRIME_NUMBERSEnabling a (modular) test should not silently enable additional kernelfunctionality, as that may increase the attack vector of a product.Fix this by making PRIME_NUMBERS_KUNIT_TEST depend on PRIME_NUMBERSinstead of selecting it.After this, one can safely enable CONFIG_KUNIT_ALL_TESTS=m to buildmodules for all appropriate tests for ones system, without pulling inextra unwanted functionality, while still allowing a tester to manuallyenable PRIME_NUMBERS and this test suite on a system where PRIME_NUMBERSis not enabled by default. Resurrect CONFIG_PRIME_NUMBERS=m intools/testing/selftests/lib/config for the latter use case.Fixes: 313b38a6ecb46db4 ("lib/prime_numbers: convert self-test to KUnit")Signed-off-by: Geert Uytterhoeven Acked-by: Tamir Duberstein Link: https://lore.kernel.org/r/40f8a40eef4930d3ac9febd205bc171eb04e171c.1744641237.git.geert@linux-m68k.orgSigned-off-by: Kees Cook List of files: /linux-6.15/tools/testing/selftests/lib/config

313b38a6 - lib/prime_numbers: convert self-test to KUnit

Sun, 09 Feb 2025 02:44:39 +0000

lib/prime_numbers: convert self-test to KUnitExtract a private header and convert the prime_numbers self-test to aKUnit test. I considered parameterizing the test using`KUNIT_CASE_PARAM` but didn't see how it was possible since the testlogic is entangled with the test parameter generation logic.Signed-off-by: Tamir Duberstein Link: https://lore.kernel.org/r/20250208-prime_numbers-kunit-convert-v5-2-b0cb82ae7c7d@gmail.comSigned-off-by: Kees Cook List of files: /linux-6.15/tools/testing/selftests/lib/config

c348c163 - lib: make a test module with set/clear bit

lib: make a test module with set/clear bitTest some bit clears/sets to make sure assembly doesn't change, and thatthe set_bit and clear_bit functions work and don't cause sparse warnings.Instruct Kbuild to build this file with extra warning level -Wextra, tocatch new issues, and also doesn't hurt to build with C=1.This was used to test changes to arch/x86/include/asm/bitops.h.In particular, sparse (C=1) was very concerned when the last bit before anatural boundary, like 7, or 31, was being tested, as this causes signextension (0xffffff7f) for instance when clearing bit 7.Recommended usage: make defconfig scripts/config -m CONFIG_TEST_BITOPS make modules_prepare make C=1 W=1 lib/test_bitops.ko objdump -S -d lib/test_bitops.ko insmod lib/test_bitops.ko rmmod lib/test_bitops.ko, there should be no compiler/sparse warnings and noerror messages in log.Link: http://lkml.kernel.org/r/20200310221747.2848474-2-jesse.brandeburg@intel.comSigned-off-by: Jesse Brandeburg Reviewed-by: Andy Shevchenko Cc: Thomas Gleixner CcL Ingo Molnar Signed-off-by: Andrew Morton Cc: Borislav Petkov Cc: Rasmus Villemoes Cc: Dan Williams Cc: Peter Zijlstra Cc: Wei Yang Cc: Christian Brauner Signed-off-by: Linus Torvalds List of files: /linux-6.15/tools/testing/selftests/lib/config
