[PATCH] kunit: cleanup assertion macro internal variables

by Daniel Latypov

All the operands should be tagged `const`. We're only assigning them to variables so that we can compare them (e.g. check if left == right, etc.) and avoid evaluating expressions multiple times. There's no need for them to be mutable. Also rename the helper variable `loc` to `__loc` like we do with `__assertion` and `__strs` to avoid potential name collisions with user code.

[RFC PATCH] kunit: flatten kunit_suite*** to kunit_suite** in executor

by Daniel Latypov

Per [1], we might not need the array-of-array of kunit_suite's. This RFC patch previews the changes we'd make to the executor to accommodate that by making the executor automatically flatten the kunit_suite*** into a kunit_suite**. The test filtering support [2] added the largest dependency on the current kunit_suite*** layout, so this patch is based on that. It actually drastically simplifies the code, so it might be useful to keep the auto-flattening step until we actually make the change.

[PATCH v2] kselftest: Fix vdso_test_abi return status

by Vincenzo Frascino

vdso_test_abi contains a batch of tests that verify the validity of the vDSO ABI. When a vDSO symbol is not found the relevant test is skipped reporting KSFT_SKIP. All the tests return values are then added in a single variable which is checked to verify failures. This approach can have side effects which result in reporting the wrong kselftest exit status. Fix vdso_test_abi verifying the return code of each test separately.

[PATCH 0/5] Miscellaneous trivial fixes

by Cristian Marussi

Hi Shuah, a small series collecting a few trivial fixes that I have already sent previously (~Dec2021) as distinct patches. They are mostly trivial patches addressing failures that seemed more sensible to be marked as skips instead. (at least to me ...). Original developers are in Cc. (but not heard back from anyone :D) Thanks, Cristian Cristian Marussi (5): selftests: skip mincore.check_file_mmap when fs lacks needed support kselftest: Fix vdso_test_time to pass on skips selftests: openat2: Print also errno in failure messages selftests: openat2: Add missing dependency in Makefile selftests: openat2: Skip testcases that fail with EOPNOTSUPP .../selftests/mincore/mincore_selftest.c | 20 +++++++++++++------ tools/testing/selftests/openat2/Makefile | 2 +- tools/testing/selftests/openat2/helpers.h | 12 ++++++----- .../testing/selftests/openat2/openat2_test.c | 12 ++++++++++- tools/testing/selftests/vDSO/vdso_test_abi.c | 3 ++- 5 files changed, 35 insertions(+), 14 deletions(-) -- 2.17.1

[RFC PATCH 00/15] rseq uapi and selftest updates

by Mathieu Desnoyers

Update the rseq selftests to adapt to the userspace ABI chosen by glibc (will be released in February 2022). Provide a fallback implementation to work with older glibc as well. Remove broken 32-bit little/big endian accessor fields in rseq uapi. Integrate various fixes gathered from librseq, including work-around for known gcc and clang compiler bugs with asm goto. The uplift to glibc's userspace ABI means we can now use %fs/%gs segment selectors directly in the inline assembler for accesses to the rseq thread area on x86. Feedback is welcome, Thanks, Mathieu Mathieu Desnoyers (15): selftests/rseq: introduce own copy of rseq uapi header rseq: Remove broken uapi field layout on 32-bit little endian selftests/rseq: Remove useless assignment to cpu variable selftests/rseq: Remove volatile from __rseq_abi selftests/rseq: Introduce rseq_get_abi() helper selftests/rseq: Introduce thread pointer getters selftests/rseq: Uplift rseq selftests for compatibility with glibc-2.35 selftests/rseq: Fix ppc32: wrong rseq_cs 32-bit field pointer on big endian selftests/rseq: Fix ppc32 missing instruction selection "u" and "x" for load/store selftests/rseq: Fix ppc32 offsets by using long rather than off_t selftests/rseq: Fix warnings about #if checks of undefined tokens selftests/rseq: Remove arm/mips asm goto compiler work-around selftests/rseq: Fix: work-around asm goto compiler bugs selftests/rseq: x86-64: use %fs segment selector for accessing rseq thread area selftests/rseq: x86-32: use %gs segment selector for accessing rseq thread area include/uapi/linux/rseq.h | 17 +- tools/testing/selftests/rseq/Makefile | 2 +- .../selftests/rseq/basic_percpu_ops_test.c | 2 +- tools/testing/selftests/rseq/compiler.h | 30 +++ tools/testing/selftests/rseq/param_test.c | 8 +- tools/testing/selftests/rseq/rseq-abi.h | 151 +++++++++++++ tools/testing/selftests/rseq/rseq-arm.h | 110 +++++----- tools/testing/selftests/rseq/rseq-arm64.h | 79 +++++-- .../rseq/rseq-generic-thread-pointer.h | 25 +++ tools/testing/selftests/rseq/rseq-mips.h | 71 ++----- .../selftests/rseq/rseq-ppc-thread-pointer.h | 30 +++ tools/testing/selftests/rseq/rseq-ppc.h | 128 +++++++---- tools/testing/selftests/rseq/rseq-s390.h | 55 +++-- tools/testing/selftests/rseq/rseq-skip.h | 2 +- .../selftests/rseq/rseq-thread-pointer.h | 19 ++ .../selftests/rseq/rseq-x86-thread-pointer.h | 40 ++++ tools/testing/selftests/rseq/rseq-x86.h | 200 ++++++++++++------ tools/testing/selftests/rseq/rseq.c | 163 +++++++------- tools/testing/selftests/rseq/rseq.h | 29 ++- 19 files changed, 793 insertions(+), 368 deletions(-) create mode 100644 tools/testing/selftests/rseq/compiler.h create mode 100644 tools/testing/selftests/rseq/rseq-abi.h create mode 100644 tools/testing/selftests/rseq/rseq-generic-thread-pointer.h create mode 100644 tools/testing/selftests/rseq/rseq-ppc-thread-pointer.h create mode 100644 tools/testing/selftests/rseq/rseq-thread-pointer.h create mode 100644 tools/testing/selftests/rseq/rseq-x86-thread-pointer.h -- 2.17.1

[PATCH net-next 1/2] mctp: test: disallow MCTP_TEST when building as a module

by Jeremy Kerr

The current kunit infrastructure defines its own module_init() when built as a module, which conflicts with the mctp core's own. So, only allow MCTP_TEST when both MCTP and KUNIT are built-in.

[PATCH 1/3] selftests/zram: Remove obsolete max_comp_streams interface

by Yang Xu

Since kernel commit 43209ea2d17a ("zram: remove max_comp_streams internals"), zram has switched to per-cpu streams. Even kernel still keep this interface for some reasons, but writing to max_comp_stream doesn't take any effect. So remove it.
