[PATCH] selftests/rseq: fix kselftest Clang build warnings

by Justin Stitt

When building with Clang, I am getting many warnings from the selftests/rseq tree. Here's one such example from rseq tree: | param_test.c:1234:10: error: address argument to atomic operation must be a pointer to _Atomic type ('intptr_t *' (aka 'long *') invalid) | 1234 | while (!atomic_load(&args->percpu_list_ptr)) {} | | ^ ~~~~~~~~~~~~~~~~~~~~~~ | /usr/local/google/home/justinstitt/repos/tc-build/build/llvm/final/lib/clang/18/include/stdatomic.h:140:29: note: expanded from macro 'atomic_load' | 140 | #define atomic_load(object) __c11_atomic_load(object, __ATOMIC_SEQ_CST) | | ^ ~~~~~~ Use compiler builtins `__atomic_load_n()` and `__atomic_store_n()` with accompanying __ATOMIC_ACQUIRE and __ATOMIC_RELEASE, respectively. This will fix the warnings because the compiler builtins do not expect their arguments to have _Atomic type. This should also make TSAN happier.

[PATCH v3 0/4] kunit: Fix some bugs in kunit

by Jinjie Ruan

The test_cases is not freed in kunit_free_suite_set(). And the copy pointer may be moved in kunit_filter_suites(). The filtered_suite and filtered_suite->test_cases allocated in the last kunit_filter_attr_tests() in last inner for loop may be leaked if kunit_filter_suites() fails. If kunit_filter_suites() succeeds, not only copy but also filtered_suite and filtered_suite->test_cases should be freed. Changes in v3: - Update the kfree_at_end() to use kunit_free_suite_set() for 4th patch. - Update the commit message for the 4th patch. Changes in v2: - Add Reviewed-by. - Add the memory leak backtrace for the 4th patch. - Remove the unused func kernel test robot noticed for the 4th patch. - Update the commit message for the 4th patch. Jinjie Ruan (4): kunit: Fix missed memory release in kunit_free_suite_set() kunit: Fix the wrong kfree of copy for kunit_filter_suites() kunit: Fix possible memory leak in kunit_filter_suites() kunit: test: Fix the possible memory leak in executor_test lib/kunit/executor.c | 23 +++++++++++++++++------ lib/kunit/executor_test.c | 35 ++++++++++++++++++++++------------- 2 files changed, 39 insertions(+), 19 deletions(-) -- 2.34.1

[PATCH v5 0/8] selftests/resctrl: Rework benchmark command handling

by Ilpo Järvinen

The benchmark command handling (-b) in resctrl selftests is overly complicated code. This series turns the benchmark command immutable to preserve it for all selftests and improves benchmark command related error handling. This series also ends up removing the strcpy() calls which were pointed out earlier. v5: - Fix another off-by-one error - Reorder local var declarations in main() to follow rev. xmas tree v4: - Correct off-by-one error in -b processing - Reordered code in main() to make freeing span_str simpler (in new patch) - Use consistent style for const char * const * v3: - Removed DEFAULT_SPAN_STR for real and the duplicated copy of defines that made to v2 likely due to my incorrect conflict resolutions v2: - Added argument length check into patch 1/7 - Updated also -b line in help message. - Document -b argument related "algorithm" - Use asprintf() to convert defined constant int to string - Improved changelog texts - Added \n to ksft_exit_fail_msg() call messages. - Print DEFAULT_SPAN with %u instead of %zu to avoid need to cast it Ilpo Järvinen (8): selftests/resctrl: Ensure the benchmark commands fits to its array selftests/resctrl: Correct benchmark command help selftests/resctrl: Remove bw_report and bm_type from main() selftests/resctrl: Simplify span lifetime selftests/resctrl: Reorder resctrl FS prep code and benchmark_cmd init selftests/resctrl: Make benchmark command const and build it with pointers selftests/resctrl: Remove ben_count variable selftests/resctrl: Cleanup benchmark argument parsing tools/testing/selftests/resctrl/cache.c | 5 +- tools/testing/selftests/resctrl/cat_test.c | 13 +-- tools/testing/selftests/resctrl/cmt_test.c | 34 ++++-- tools/testing/selftests/resctrl/mba_test.c | 4 +- tools/testing/selftests/resctrl/mbm_test.c | 7 +- tools/testing/selftests/resctrl/resctrl.h | 16 +-- .../testing/selftests/resctrl/resctrl_tests.c | 100 ++++++++---------- tools/testing/selftests/resctrl/resctrl_val.c | 10 +- 8 files changed, 104 insertions(+), 85 deletions(-) -- 2.30.2

[PATCH] selftests/mm: Fix awk usage in charge_reserved_hugetlb.sh and hugetlb_reparenting_test.sh that may cause error

by Juntong Deng

According to the awk manual, the -e option does not need to be specified in front of 'program' (unless you need to mix program-file). The redundant -e option can cause error when users use awk tools other than gawk (for example, mawk does not support the -e option).
