Uriel Guajardo 359a376081 kunit: support failure from dynamic analysis tools ... Add a kunit_fail_current_test() function to fail the currently running test, if any, with an error message. This is largely intended for dynamic analysis tools like UBSAN and for fakes. E.g. say I had a fake ops struct for testing and I wanted my `free` function to complain if it was called with an invalid argument, or caught a double-free. Most return void and have no normal means of signalling failure (e.g. super_operations, iommu_ops, etc.). Key points: * Always update current->kunit_test so anyone can use it. * commit 83c4e7a036 ("KUnit: KASAN Integration") only updated it for CONFIG_KASAN=y * Create a new header <kunit/test-bug.h> so non-test code doesn't have to include all of <kunit/test.h> (e.g. lib/ubsan.c) * Forward the file and line number to make it easier to track down failures * Declare the helper function for nice __printf() warnings about mismatched format strings even when KUnit is not enabled. Example output from kunit_fail_current_test("message"): [15:19:34] [FAILED] example_simple_test [15:19:34] # example_simple_test: initializing [15:19:34] # example_simple_test: lib/kunit/kunit-example-test.c:24: message [15:19:34] not ok 1 - example_simple_test Fixed minor check patch with checkpatch --fix option: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: Daniel Latypov <dlatypov@google.com> Signed-off-by: Uriel Guajardo <urielguajardo@google.com> Reviewed-by: Alan Maguire <alan.maguire@oracle.com> Reviewed-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>		2021-04-02 14:19:58 -06:00
