[PATCH] selftests/ftrace: Fix dependencies for some of the synthetic event tests

by Naveen N Rao

Commit b81a3a100cca1b ("tracing/histogram: Add simple tests for stacktrace usage of synthetic events") changed the output text in tracefs README, but missed updating some of the dependencies specified in selftests. This causes some of the tests to exit as unsupported. Fix this by changing the grep pattern. Since we want these tests to work on older kernels, match only against the common last part of the pattern.

[PATCH v3] KVM: selftests: Add new CFLAGS to generate dependency files

by Yu Zhang

Add "-MD" in CFLAGS to generate dependency files. Currently, each time a header file is updated in KVM selftest, we will have to run "make clean && make" to rebuild the whole test suite. By adding new compiling flags and dependent rules in Makefile, we do not need to make clean && make each time a header file is updated.

[PATCH bpf v5 0/2] bpf: fix NULL dereference during extable search

by Krister Johansen

Hi, Enclosed are a pair of patches for an oops that can occur if an exception is generated while a bpf subprogram is running. One of the bpf_prog_aux entries for the subprograms are missing an extable. This can lead to an exception that would otherwise be handled turning into a NULL pointer bug. These changes were tested via the verifier and progs selftests and no regressions were observed. Changes from v4: - Ensure that num_exentries is copied to prog->aux from func[0] (Feedback from Ilya Leoshkevich) Changes from v3: - Selftest style fixups (Feedback from Yonghong Song) - Selftest needs to assert that test bpf program executed (Feedback from Yonghong Song) - Selftest should combine open and load using open_and_load (Feedback from Yonghong Song) Changes from v2: - Insert only the main program's kallsyms (Feedback from Yonghong Song and Alexei Starovoitov) - Selftest should use ASSERT instead of CHECK (Feedback from Yonghong Song) - Selftest needs some cleanup (Feedback from Yonghong Song) - Switch patch order (Feedback from Alexei Starovoitov) Changes from v1: - Add a selftest (Feedback From Alexei Starovoitov) - Move to a 1-line verifier change instead of searching multiple extables Krister Johansen (2): bpf: ensure main program has an extable selftests/bpf: add a test for subprogram extables kernel/bpf/verifier.c | 7 ++- .../bpf/prog_tests/subprogs_extable.c | 29 +++++++++++ .../bpf/progs/test_subprogs_extable.c | 51 +++++++++++++++++++ 3 files changed, 85 insertions(+), 2 deletions(-) create mode 100644 tools/testing/selftests/bpf/prog_tests/subprogs_extable.c create mode 100644 tools/testing/selftests/bpf/progs/test_subprogs_extable.c -- 2.25.1

[RFC v1 0/6] kunit: Add test attributes API

by Rae Moar

Hello everyone, This is an RFC patch series to propose the addition of a test attributes framework to KUnit. There has been interest in filtering out "slow" KUnit tests. Most notably, a new config, CONFIG_MEMCPY_SLOW_KUNIT_TEST, has been added to exclude particularly slow memcpy tests (https://lore.kernel.org/all/20230118200653.give.574-kees@kernel.org/). This proposed attributes framework would be used to save and access test associated data, including whether a test is slow. These attributes would be reportable (via KTAP and command line output) and some will be filterable. This framework is designed to allow for the addition of other attributes in the future. These attributes could include whether the test is flaky, associated test files, etc. Note that this could intersect with the discussions on how to format test-associated data in KTAP v2 that I am also involved in (https://lore.kernel.org/all/20230420205734.1288498-1-rmoar@google.com/). If the overall idea seems good, I'll make sure to add tests/documentation, and more patches marking existing tests as slow to the patch series. Thanks!
