[PATCH V3 0/4] selftests: Remove duplicate CPUID wrappers

by Reinette Chatre

Changes since V2: - V2: https://lore.kernel.org/lkml/cover.1647360971.git.reinette.chatre@intel.com/ - Rebased against v5.18-rc4, no functional changes. - Add text in cover letter and first patch to highlight that the __cpuid_count() macro provided is not a new implementation but copied from gcc. Changes since V1: - V1: https://lore.kernel.org/lkml/cover.1644000145.git.reinette.chatre@intel.com/ - Change solution to not use __cpuid_count() from compiler's cpuid.h but instead use a local define of __cpuid_count() provided in kselftest.h to ensure tests continue working in all supported environments. (Shuah) - Rewrite cover letter and changelogs to reflect new solution. A few tests that require running CPUID do so with a private implementation of a wrapper for CPUID. This duplication of the CPUID wrapper should be avoided. Both gcc and clang/LLVM provide wrappers for CPUID but the wrappers are not available in the minimal required version of gcc, v3.2, that the selftests need to be used in. __cpuid_count() was added to gcc in v4.4, which is ok for kernels after v4.19 when the gcc minimal required version was changed to v4.6. Copy gcc's __cpuid_count() to provide a local define of __cpuid_count() to kselftest.h to ensure that selftests can still work in environments with older stable kernels (v4.9 and v4.14 that have the minimal required version of gcc of v3.2). Update tests with private CPUID wrappers to use the new macro.

[PATCH 0/5] Firmware loader support for ZSTD-compressed files

by Takashi Iwai

Hi, this is a revised patch set for RFC I posted some time ago (*). Since the ZSTD usage became much more popular now, it makes sense to have the consistent (de)compression support in the kernel, also for the firmware files. This patch set adds the support for ZSTD- compressed firmware files as well as the extension of selftests, in addition to a couple of relevant fixes in selftests.

[PATCH] selftests/resctrl: Fix null pointer dereference on open failed

by Colin Ian King

Currently if opening /dev/null fails to open then file pointer fp is null and further access to fp via fprintf will cause a null pointer dereference. Fix this by returning a negative error value when a null fp is detected.

[PATCH v4 0/4] memcg: introduce per-memcg proactive reclaim

by Yosry Ahmed

This patch series adds a memory.reclaim proactive reclaim interface. The rationale behind the interface and how it works are in the first patch. --- Changes in V4: mm/memcontrol.c: - Return -EINTR on signal_pending(). - On the final retry, drain percpu lru caches hoping that it might introduce some evictable pages for reclaim. - Simplified the retry loop as suggested by Dan Schatzberg. selftests: - Always return -errno on failure from cg_write() (whether open() or write() fail), also update cg_read() and read_text() to return -errno as well for consistency. Also make sure to correctly check that the whole buffer was written in cg_write(). - Added a maximum number of retries for the reclaim selftest. Changes in V3: - Fix cg_write() (in patch 2) to properly return -1 if open() fails and not fail if len == errno. - Remove debug printf() in patch 3. Changes in V2: - Add the interface to root as well. - Added a selftest. - Documented the interface as a nested-keyed interface, which makes adding optional arguments in the future easier (see doc updates in the first patch). - Modified the commit message to reflect changes and added a timeout argument as a suggested possible extension - Return -EAGAIN if the kernel fails to reclaim the full requested amount. --- Shakeel Butt (1): memcg: introduce per-memcg reclaim interface Yosry Ahmed (3): selftests: cgroup: return -errno from cg_read()/cg_write() on failure selftests: cgroup: fix alloc_anon_noexit() instantly freeing memory selftests: cgroup: add a selftest for memory.reclaim Documentation/admin-guide/cgroup-v2.rst | 21 +++++ mm/memcontrol.c | 44 +++++++++ tools/testing/selftests/cgroup/cgroup_util.c | 44 ++++----- .../selftests/cgroup/test_memcontrol.c | 94 ++++++++++++++++++- 4 files changed, 176 insertions(+), 27 deletions(-) -- 2.36.0.rc2.479.g8af0fa9b8e-goog

[PATCH 1/2] selftests: vm: refactor run_vmtests.sh to reduce boilerplate

by Axel Rasmussen

Previously, each test printed out its own header, dealt with its own return code, etc. By just putting this standard stuff in a function, we can delete > 300 lines from the script. This also makes adding future tests easier. And, it gets rid of various inconsistencies that already exist: - Some tests correctly deal with ksft_skip, but others don't. - Some tests just print the executable name, others print arguments, and yet others print some comment in the header. - Most tests print out a header with two separator lines, but not the HMM smoke test or the memfd_secret test, which only print one. - We had a redundant "exit" at the end, with all the boilerplate it's an easy oversight.

[PATCH v2 0/4] kselftest/arm64: Miscelaneous MTE test updates

by Mark Brown

This series is just a set of minor tweaks and improvements for the MTE tests that I did while working on the asymmetric mode support for userspace which seemed like they might be worth keeping even though the prctl() for asymmetric mode got removed. v2: - Rebase onto v5.18-rc3 Mark Brown (4): kselftest/arm64: Handle more kselftest result codes in MTE helpers kselftest/arm64: Log unexpected asynchronous MTE faults kselftest/arm64: Refactor parameter checking in mte_switch_mode() kselftest/arm64: Add simple test for MTE prctl tools/testing/selftests/arm64/mte/.gitignore | 1 + .../testing/selftests/arm64/mte/check_prctl.c | 119 ++++++++++++++++++ .../selftests/arm64/mte/mte_common_util.c | 19 ++- .../selftests/arm64/mte/mte_common_util.h | 15 ++- 4 files changed, 149 insertions(+), 5 deletions(-) create mode 100644 tools/testing/selftests/arm64/mte/check_prctl.c base-commit: b2d229d4ddb17db541098b83524d901257e93845 -- 2.30.2

[PATCH v2 0/3] kselftest/arm64: Test ptrace writing via FPSIMD and reading via SVE

by Mark Brown

This series has a couple of minor fixes and cleanups for sve-ptrace plus the addition of a new test which validates that we can write using the FPSIMD regset and then read matching data back using the SVE regset - previously we only validated writing SVE and reading FPSIMD data. v2 - Rebase onto v5.18-rc1 Mark Brown (3): kselftest/arm64: Fix comment for ptrace_sve_get_fpsimd_data() kselftest/arm64: Remove assumption that tasks start FPSIMD only kselftest/arm64: Validate setting via FPSIMD and read via SVE regsets tools/testing/selftests/arm64/fp/sve-ptrace.c | 164 +++++++++++++++--- 1 file changed, 139 insertions(+), 25 deletions(-) base-commit: 3123109284176b1532874591f7c81f3837bbdc17 -- 2.30.2
