Hi, This builds on the proposal[1] from Mark and lets me convert the existing usercopy selftest to KUnit. Besides adding this basic test to the KUnit collection, it also opens the door for execve testing (which depends on having a functional current->mm), and should provide the basic infrastructure for adding Mark's much more complete usercopy tests. -Kees [1] https://lore.kernel.org/lkml/20230321122514.1743889-2-mark.rutland@xxxxxxx/ Kees Cook (2): kunit: test: Add vm_mmap() allocation resource manager usercopy: Convert test_user_copy to KUnit test MAINTAINERS | 1 + include/kunit/test.h | 17 ++ lib/Kconfig.debug | 21 +- lib/Makefile | 2 +- lib/kunit/test.c | 139 +++++++++++- lib/{test_user_copy.c => usercopy_kunit.c} | 252 ++++++++++----------- 6 files changed, 288 insertions(+), 144 deletions(-) rename lib/{test_user_copy.c => usercopy_kunit.c} (52%) -- 2.34.1
