2019-03-07lib/test_ubsan.c: VLA no longer used in kernelOlof Johansson1-10/+1
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] Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Olof Johansson <[email protected]> Acked-by: Dmitry Vyukov <[email protected]> Cc: Colin Ian King <[email protected]> Cc: Jinbum Park <[email protected]> Cc: Andrey Ryabinin <[email protected]> Cc: Kees Cook <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2018-04-11lib/test_ubsan.c: make test_ubsan_misaligned_access() staticColin Ian King1-1/+1
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?

2018-04-11lib: add testing module for UBSANJinbum Park1-0/+144
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.
