[PATCH] selftests/mm: refactor common code and improve test skipping in guard_region

by wang lian

Move the generic `FORCE_READ` macro from `guard-regions.c` to the shared `vm_util.h` header to promote code reuse. In `guard-regions.c`, replace `ksft_exit_skip()` with the `SKIP()` macro to ensure only the current test is skipped on permission failure, instead of terminating the entire test binary.

[PATCH net 0/2] selftests: mptcp: connect: cover alt modes

by Matthieu Baerts (NGI0)

mptcp_connect.sh can be executed manually with "-m <MODE>" and "-C" to make sure everything works as expected when using "mmap" and "sendfile" modes instead of "poll", and with the MPTCP checksum support. These modes should be validated, but they are not when the selftests are executed via the kselftest helpers. It means that most CIs validating these selftests, like NIPA for the net development trees and LKFT for the stable ones, are not covering these modes. To fix that, new test programs have been added, simply calling mptcp_connect.sh with the right parameters. The first patch can be backported up to v5.6, and the second one up to v5.14.

[PATCH v4 0/7] Add support for FEAT_{LS64, LS64_V} and related tests

by Yicong Yang

From: Yicong Yang <yangyicong(a)hisilicon.com> Armv8.7 introduces single-copy atomic 64-byte loads and stores instructions and its variants named under FEAT_{LS64, LS64_V}. Add support for Armv8.7 FEAT_{LS64, LS64_V}: - Add identifying and enabling in the cpufeature list - Expose the support of these features to userspace through HWCAP3 and cpuinfo - Add related hwcap test - Handle the trap of unsupported memory (normal/uncacheable) access in a VM A real scenario for this feature is that the userspace driver can make use of this to implement direct WQE (workqueue entry) - a mechanism to fill WQE directly into the hardware.

[PATCH 00/15] selftests/futex: Refactor tests to use kselftest_harness.h

by André Almeida

This patch series refactors all futex selftests to use kselftest_harness.h instead of futex's logging.h, as discussed here [1]. This allows to remove a lot of boilerplate code and to simplify some parts of the test logic, mainly when the test needs to exit early. The result of this is more than 500 lines removed from tools/testing/selftests/futex/. Also, this enables new tests to use kselftest.h features like ASSERT_s and such. There are some caveats around this refactor: - logging.h had verbosity levels, while kselftest_harness.h doesn't. I created a new print function called ksft_print_dbg_msg() that prints the message if the user uses the -d flag, so now there's an equivalent of this feature. - futex_requeue_pi test accepted command line arguments to be used as test parameters (e.g. ./futex_requeue_pi -b -l -t 500000). This doesn't work with kselftest_harness.h because there's no straightforward way to send command line arguments to the test. I used FIXTURE_VARIANT() to achieve the same result, but now the parameters live inside of the test file, instead of on functional/run.sh. This increased a little bit the number of test cases for futex_requeue_pi, from 22 to 24. - test_harness_run() calls mmap(MAP_SHARED) before running the test and this has caused a side effect on test futex_numa_mpol.c. This test also calls mmap() and then try to access an address out of boundaries of this mapped memory for a "Memory out of range" subtest, where the kernel should return -EACCESS. After the refactor, the test address might be fall inside the first memory mapped region, thus being a valid address and succeeding the syscall, making the test fail. To fix that, I created a small "buffer zone" with mmap(PROT_NONE) between both mmaps. I have compared the results of run.sh before and after this patchset and didn't find any regression from the test results.

[ANNOUNCE/CFP] Kernel Testing & Dependability Micro-conference at LPC Japan 2025

by Arisu Tachibana

Hello everyone, I am reaching out to announce that we are once again planning to gather to discuss testing and dependability related topics at the Kernel Testing & Dependability Micro-conference (a.k.a. Testing MC) at Linux Plumbers Conference Japan 2025. - https://lpc.events/event/19/sessions/228/ The Linux Plumbers 2025 Kernel Testing & Dependability track focuses on advancing the current state of testing of the Linux Kernel and its related infrastructure. The main purpose is to improve software quality and dependability for applications that require predictability and trust. We aim to create connections between folks working on similar projects, and help individual projects make progress. This track is intended to promote collaboration between all the communities and people interested in the Kernel testing & dependability. This will help move the conversation forward from where we left off at the LPC 2024 Kernel Testing & Dependability MC. We ask that any topic discussions focus on issues/problems they are facing and possible alternatives to resolving them. The Micro-conference is open to all topics related to testing on Linux, not necessarily in the kernel space. Suggested topics: - KernelCI: Maestro, kci-dev, kci-deploy, kci-gitlab, new dashboard, KCIDB-ng - Improve sanitizers: KFENCE, KCSAN, KASAN, UBSAN - Using Clang for better testing coverage: Now that the kernel fully supports building with Clang, how can all that work be leveraged into using Clang's features? - Consolidating toolchains: reference collection for increased reproducibility and quality control. - How to spread KUnit throughout the kernel? - Building and testing in-kernel Rust code. - Identify missing features that will provide assurance in safety critical systems. - Which test coverage infrastructures are most effective to provide evidence for kernel quality assurance? How should it be measured? - Explore ways to improve testing framework and tests in the kernel with a specific goal to increase traceability and code coverage. - Regression Testing for safety: Prioritize configurations and tests critical and important for quality and dependability. - Transitioning to test-driven kernel release cycles for mainline and stable: How to start relying on passing tests before releasing a new tag? - Explore how do SBOMs figure into dependability? - Kernel benchmarking and kernel performance evaluation. We invite you to submit proposals for discussions. Proposals can be submitted here, by 11:59PM UTC on Wednesday, September 10, 2025: - https://lpc.events/event/19/abstracts/ Please send any inquiries to the MC leads: Arisu Tachibana <arisu.tachibana(a)miraclelinux.com> Shuah Khan <shuah(a)kernel.org> Sasha Levin <sashal(a)kernel.org> Guillaume Tucker <gtucker(a)gtucker.io> thank you, -- Arisu

[PATCH net] selftests: rtnetlink: try double sleep to give WQ a chance

by Jakub Kicinski

The rtnetlink test for preferred lifetime of an address is quite flaky. Problems started around the 6.16 merge window in May. The test fails with: FAIL: preferred_lft addresses remaining and unlike most of our flakes this one fails on the "normal" kernel builds, not the builds with kernel/configs/debug.config. I suspect the flakes may be related to power saving, since the expirations run from a "power efficient" workqueue. Adding a short sleep seems to decrease the flakes by 8x but they still happen. With this patch in place we get a flake every couple of weeks, not every couple of days. Better ideas welcome..
