kunit/usercopy: Disable testing on !CONFIG_MMU

2024-07-02T16:11:40Z

Since arch_pick_mmap_layout() is an inline for non-MMU systems, disable this test there. Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202406160505.uBge6TMY-lkp@intel.com/ Signed-off-by: Kees Cook Reviewed-by: Rae Moar Reviewed-by: David Gow Signed-off-by: Shuah Khan

usercopy: Convert test_user_copy to KUnit test

2024-06-15T01:31:39Z

Convert the runtime tests of hardened usercopy to standard KUnit tests. Additionally disable usercopy_test_invalid() for systems with separate address spaces (or no MMU) since it's not sensible to test for address confusion there (e.g. m68k).
