  • 9d7ca61b1   lib/test_ubsan.c: VLA no longer used in kernel ... Browse Code »

    Since we now build with -Wvla, any use of VLA throws a warning.
    Including this test, so... maybe we should just remove the test?

    lib/test_ubsan.c: In function 'test_ubsan_vla_bound_not_positive':
    lib/test_ubsan.c:48:2: warning: ISO C90 forbids variable length array 'buf' [-Wvla]

    For the out-of-bounds test, switch to non-VLA setup.

    lib/test_ubsan.c: In function 'test_ubsan_out_of_bounds':
    lib/test_ubsan.c:64:2: warning: ISO C90 forbids variable length array 'arr' [-Wvla]

    test_ubsan_misaligned_access() is local to the source and does not need
    to be in global scope, so make it static.

    Cleans up sparse warning:

    lib/test_ubsan.c:91:6: warning: symbol 'test_ubsan_misaligned_access' was not declared. Should it be static?

  • 854686f4e   lib: add testing module for UBSAN ... Browse Code »

    This is a test module for UBSAN. It triggers all undefined behaviors
    that linux supports now, and detect them.

    All test-cases have passed by compiling with gcc-5.5.0.

    If use gcc-4.9.x, misaligned, out-of-bounds, object-size-mismatch will not
    be detected. Because gcc-4.9.x doesn't support them.
