[PATCH v2 0/2] kunit: fail tests on UBSAN errors

by Daniel Latypov

v1 by Uriel is here: [1]. Since it's been a while, I've dropped the Reviewed-By's. It depended on commit 83c4e7a0363b ("KUnit: KASAN Integration") which hadn't been merged yet, so that caused some kerfuffle with applying them previously and the series was reverted. This revives the series but makes the kunit_fail_current_test() function take a format string and logs the file and line number of the failing code, addressing Alan Maguire's comments on the previous version. As a result, the patch that makes UBSAN errors was tweaked slightly to include an error message.

Correct .gitignore in several places for kselftest outputs

by Erik Hollensbe

Sincerely hope I did this right; first time contributor, learning the patch workflow. I took the opportunity to fix two .gitignore files that were leaving stale worktree/index outputs after running `make kselftest` against recent mainline (76c057c84d286140c6c416c3b4ba832cd1d8984e). Thanks for your time!

[PATCH] selftests/core: fix close_range_test build after XFAIL removal

by Tobias Klauser

XFAIL was removed in commit 9847d24af95c ("selftests/harness: Refactor XFAIL into SKIP") and its use in close_range_test was already replaced by commit 1d44d0dd61b6 ("selftests: core: use SKIP instead of XFAIL in close_range_test.c"). However, commit 23afeaeff3d9 ("selftests: core: add tests for CLOSE_RANGE_CLOEXEC") introduced usage of XFAIL in TEST(close_range_cloexec). Use SKIP there as well.

[PATCH 1/5] kselftests: dmabuf-heaps: Fix Makefile's inclusion of the kernel's usr/include dir

by John Stultz

Copied in from somewhere else, the makefile was including the kerne's usr/include dir, which caused the asm/ioctl.h file to be used. Unfortunately, that file has different values for _IOC_SIZEBITS and _IOC_WRITE than include/uapi/asm-generic/ioctl.h which then causes the _IOCW macros to give the wrong ioctl numbers, specifically for DMA_BUF_IOCTL_SYNC. This patch simply removes the extra include from the Makefile Cc: Shuah Khan <shuah(a)kernel.org> Cc: Brian Starkey <brian.starkey(a)arm.com> Cc: Sumit Semwal <sumit.semwal(a)linaro.org> Cc: Laura Abbott <labbott(a)kernel.org> Cc: Hridya Valsaraju <hridya(a)google.com> Cc: Suren Baghdasaryan <surenb(a)google.com> Cc: Sandeep Patil <sspatil(a)google.com> Cc: Daniel Mentz <danielmentz(a)google.com> Cc: linux-media(a)vger.kernel.org Cc: dri-devel(a)lists.freedesktop.org Cc: linux-kselftest(a)vger.kernel.org Fixes: a8779927fd86c ("kselftests: Add dma-heap test") Signed-off-by: John Stultz <john.stultz(a)linaro.org> --- tools/testing/selftests/dmabuf-heaps/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/dmabuf-heaps/Makefile b/tools/testing/selftests/dmabuf-heaps/Makefile index 607c2acd2082..604b43ece15f 100644 --- a/tools/testing/selftests/dmabuf-heaps/Makefile +++ b/tools/testing/selftests/dmabuf-heaps/Makefile @@ -1,5 +1,5 @@ # SPDX-License-Identifier: GPL-2.0 -CFLAGS += -static -O3 -Wl,-no-as-needed -Wall -I../../../../usr/include +CFLAGS += -static -O3 -Wl,-no-as-needed -Wall TEST_GEN_PROGS = dmabuf-heap -- 2.25.1
