From: Jeff Xu <jeffxu@xxxxxxxxxxxx> This series increase the test coverage of mseal_test by: Add check for vma_size, prot, and error code for existing tests. Add more testcases for madvise, munmap, mmap and mremap to cover sealing in different scenarios. The increase test coverage hopefully help to prevent future regression. It doesn't change any existing mm api's semantics, i.e. it will pass on linux main and 6.10 branch. Note: in order to pass this test in mm-unstable, mm-unstable must have Liam's fix on mmap [1] [1] https://lore.kernel.org/linux-kselftest/vyllxuh5xbqmaoyl2mselebij5ox7cseekjcvl5gmzoxxwd2he@hxi4mpjanxzt/#t History: V2: - remove the mmap fix (Liam R. Howlett will fix it separately) - Add cover letter (Lorenzo Stoakes) - split the testcase for ease of review (Mark Brown) V1: - https://lore.kernel.org/linux-kselftest/20240828225522.684774-1-jeffxu@xxxxxxxxxxxx/ Jeff Xu (4): selftests/mm: mseal_test, add vma size check selftests/mm: mseal_test add sealed madvise type selftests/mm: mseal_test add more tests for mmap selftests/mm: mseal_test add more tests for mremap tools/testing/selftests/mm/mseal_test.c | 829 ++++++++++++++++++++++-- 1 file changed, 762 insertions(+), 67 deletions(-) -- 2.46.0.469.g59c65b2a67-goog
