lib/prime_numbers: KUnit test should not select PRIME_NUMBERS

2025-04-15T20:50:43+00:00

Enabling a (modular) test should not silently enable additional kernel functionality, as that may increase the attack vector of a product. Fix this by making PRIME_NUMBERS_KUNIT_TEST depend on PRIME_NUMBERS instead of selecting it. After this, one can safely enable CONFIG_KUNIT_ALL_TESTS=m to build modules for all appropriate tests for ones system, without pulling in extra unwanted functionality, while still allowing a tester to manually enable PRIME_NUMBERS and this test suite on a system where PRIME_NUMBERS is not enabled by default. Resurrect CONFIG_PRIME_NUMBERS=m in tools/testing/selftests/lib/config for the latter use case.

scanf: convert self-test to KUnit

2025-03-14T20:55:37+00:00

Convert the scanf() self-test to a KUnit test. In the interest of keeping the patch reasonably-sized this doesn't refactor the tests into proper parameterized tests - it's all one big test case.

lib/prime_numbers: convert self-test to KUnit

2025-02-12T22:00:11+00:00

Extract a private header and convert the prime_numbers self-test to a KUnit test. I considered parameterizing the test using `KUNIT_CASE_PARAM` but didn't see how it was possible since the test logic is entangled with the test parameter generation logic.

The strscpy test loads test_strscpy module for testing. But test_strscpy was converted to Kunit (see fixes). Hence remove strscpy. Fixes: 41eefc46a3a4 ("string: Convert strscpy() self-test to KUnit") Signed-off-by: Muhammad Usama Anjum Signed-off-by: Shuah Khan

lib: make a test module with set/clear bit

2020-06-05T02:06:25+00:00

Test some bit clears/sets to make sure assembly doesn't change, and that the set_bit and clear_bit functions work and don't cause sparse warnings. Instruct Kbuild to build this file with extra warning level -Wextra, to catch 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 a natural boundary, like 7, or 31, was being tested, as this causes sign extension (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 no error messages in log.
