[PATCH] selftests/nolibc: only run constructor tests on nolibc

by Thomas Weißschuh

The nolibc testsuite can be run against other libcs to test for interoperability. Some aspects of the constructor execution are not standardized and musl does not provide all tested feature, for one it does not provide arguments to the constructors, anymore? Skip the constructor tests on non-nolibc configurations.

[PATCH] kunit: constify return of string literals

by Christian Göttsche

From: Christian Göttsche <cgzones(a)googlemail.com> The function kunit_status_to_ok_not_ok() returns string literals, thus declare the return value as such.

[PATCH V3 0/3] selftests: add ublk selftests

by Ming Lei

Hello Jens, This patchset adds ublk kernel selftests, which is very handy for developer for verifying kernel change, especially ublk heavily depends on io_uring subsystem. Also it provides template for target implementation. Please consider it for v6.15. The 1st patch adds one ublk utility and one entry test. The 2nd patch adds test over file backed ublk. The 3rd patch adds test for ublk zero copy. How to run: - make install - make headers_install INSTALL_HDR_PATH=/usr # in case UAPI is changed - reboot - make -C tools/testing/selftests TARGETS=ublk run_test Thanks, V3: - re-organize code, and move target code into standalone source file - fix one error handling bug - add licence tag - add dma limit for zero copy file backed target - kill checkpatch ERROR V2: - fix one sqe allocation bug, so ublk zero copy with io_link can pass - dump log in case of error - add one more test for mkfs/mount on zero copy Ming Lei (3): selftests: ublk: add kernel selftests for ublk selftests: ublk: add file backed ublk selftests: ublk: add ublk zero copy test MAINTAINERS | 1 + tools/testing/selftests/Makefile | 1 + tools/testing/selftests/ublk/.gitignore | 3 + tools/testing/selftests/ublk/Makefile | 16 + tools/testing/selftests/ublk/config | 1 + tools/testing/selftests/ublk/file_backed.c | 220 ++++ tools/testing/selftests/ublk/kublk.c | 1110 ++++++++++++++++++ tools/testing/selftests/ublk/kublk.h | 326 +++++ tools/testing/selftests/ublk/null.c | 38 + tools/testing/selftests/ublk/test_common.sh | 113 ++ tools/testing/selftests/ublk/test_loop_01.sh | 31 + tools/testing/selftests/ublk/test_loop_02.sh | 22 + tools/testing/selftests/ublk/test_loop_03.sh | 33 + tools/testing/selftests/ublk/test_loop_04.sh | 22 + tools/testing/selftests/ublk/test_null_01.sh | 19 + 15 files changed, 1956 insertions(+) create mode 100644 tools/testing/selftests/ublk/.gitignore create mode 100644 tools/testing/selftests/ublk/Makefile create mode 100644 tools/testing/selftests/ublk/config create mode 100644 tools/testing/selftests/ublk/file_backed.c create mode 100644 tools/testing/selftests/ublk/kublk.c create mode 100644 tools/testing/selftests/ublk/kublk.h create mode 100644 tools/testing/selftests/ublk/null.c create mode 100755 tools/testing/selftests/ublk/test_common.sh create mode 100755 tools/testing/selftests/ublk/test_loop_01.sh create mode 100755 tools/testing/selftests/ublk/test_loop_02.sh create mode 100755 tools/testing/selftests/ublk/test_loop_03.sh create mode 100755 tools/testing/selftests/ublk/test_loop_04.sh create mode 100755 tools/testing/selftests/ublk/test_null_01.sh -- 2.47.0

[PATCH bpf-next v1 0/3] Optimize bpf selftest to increase CI success rate

by Jiayuan Chen

1. Optimized some static bound port selftests to avoid port occupation when running test_progs -j. 2. Optimized the retry logic for test_maps.
