Two small cleanups for selftests, drop duplicate max/min definitions. v3: - move '#include <sys/param.h>' into test_progs.h. v2: - do more cleanups as Daniel suggested. v1: - "selftests: bpf: use MIN for TCP CC tests" Geliang Tang (2): selftests: bpf: drop duplicate max/min definitions selftests: mqueue: drop duplicate min definition tools/testing/selftests/bpf/prog_tests/bpf_iter.c | 4 +--- tools/testing/selftests/bpf/prog_tests/bpf_tcp_ca.c | 6 ++---- tools/testing/selftests/bpf/prog_tests/snprintf.c | 4 +--- tools/testing/selftests/bpf/prog_tests/tc_redirect.c | 1 - tools/testing/selftests/bpf/test_progs.h | 1 + tools/testing/selftests/mqueue/mq_perf_tests.c | 4 ++-- 6 files changed, 7 insertions(+), 13 deletions(-) -- 2.34.1

[PATCH v1 0/4] selftests/arm64: Fix O= builds for the FP selftests

by Mark Brown

Currently the arm64 selftests don't support building with O=, this series fixes that, bringing them more into line with how the kselftest Makefiles want to work.

[PATCH bpf-next v4 0/4] bpf: RLIMIT_MEMLOCK cleanups

by Yafang Shao

We have switched to memcg-based memory accouting and thus the rlimit is not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in libbpf for backward compatibility, so we can use it instead now. This patchset cleanups the usage of RLIMIT_MEMLOCK in tools/bpf/, tools/testing/selftests/bpf and samples/bpf. The file tools/testing/selftests/bpf/bpf_rlimit.h is removed. The included header sys/resource.h is removed from many files as it is useless in these files. - v4: Squash patches and use customary subject prefixes. (Andrii) - v3: Get rid of bpf_rlimit.h and fix some typos (Andrii) - v2: Use libbpf_set_strict_mode instead. (Andrii) - v1: https://lore.kernel.org/bpf/20220320060815.7716-2-laoar.shao@gmail.com/ Yafang Shao (4): samples/bpf: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK selftests/bpf: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK bpftool: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK tools/runqslower: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK samples/bpf/cpustat_user.c | 1 - samples/bpf/hbm.c | 5 ++-- samples/bpf/ibumad_user.c | 1 - samples/bpf/map_perf_test_user.c | 1 - samples/bpf/offwaketime_user.c | 1 - samples/bpf/sockex2_user.c | 1 - samples/bpf/sockex3_user.c | 1 - samples/bpf/spintest_user.c | 1 - samples/bpf/syscall_tp_user.c | 1 - samples/bpf/task_fd_query_user.c | 1 - samples/bpf/test_lru_dist.c | 1 - samples/bpf/test_map_in_map_user.c | 1 - samples/bpf/test_overhead_user.c | 1 - samples/bpf/tracex2_user.c | 1 - samples/bpf/tracex3_user.c | 1 - samples/bpf/tracex4_user.c | 1 - samples/bpf/tracex5_user.c | 1 - samples/bpf/tracex6_user.c | 1 - samples/bpf/xdp1_user.c | 1 - samples/bpf/xdp_adjust_tail_user.c | 1 - samples/bpf/xdp_monitor_user.c | 1 - samples/bpf/xdp_redirect_cpu_user.c | 1 - samples/bpf/xdp_redirect_map_multi_user.c | 1 - samples/bpf/xdp_redirect_user.c | 1 - samples/bpf/xdp_router_ipv4_user.c | 1 - samples/bpf/xdp_rxq_info_user.c | 1 - samples/bpf/xdp_sample_pkts_user.c | 1 - samples/bpf/xdp_sample_user.c | 1 - samples/bpf/xdp_tx_iptunnel_user.c | 1 - samples/bpf/xdpsock_user.c | 9 ++---- samples/bpf/xsk_fwd.c | 7 ++--- tools/bpf/bpftool/common.c | 8 ------ tools/bpf/bpftool/feature.c | 2 -- tools/bpf/bpftool/main.c | 6 ++-- tools/bpf/bpftool/main.h | 2 -- tools/bpf/bpftool/map.c | 2 -- tools/bpf/bpftool/pids.c | 1 - tools/bpf/bpftool/prog.c | 3 -- tools/bpf/bpftool/struct_ops.c | 2 -- tools/bpf/runqslower/runqslower.c | 18 ++---------- tools/testing/selftests/bpf/bench.c | 1 - tools/testing/selftests/bpf/bpf_rlimit.h | 28 ------------------- .../selftests/bpf/flow_dissector_load.c | 6 ++-- .../selftests/bpf/get_cgroup_id_user.c | 4 ++- tools/testing/selftests/bpf/prog_tests/btf.c | 1 - .../selftests/bpf/test_cgroup_storage.c | 4 ++- tools/testing/selftests/bpf/test_dev_cgroup.c | 4 ++- tools/testing/selftests/bpf/test_lpm_map.c | 4 ++- tools/testing/selftests/bpf/test_lru_map.c | 4 ++- .../selftests/bpf/test_skb_cgroup_id_user.c | 4 ++- tools/testing/selftests/bpf/test_sock.c | 4 ++- tools/testing/selftests/bpf/test_sock_addr.c | 4 ++- tools/testing/selftests/bpf/test_sockmap.c | 5 ++-- tools/testing/selftests/bpf/test_sysctl.c | 4 ++- tools/testing/selftests/bpf/test_tag.c | 4 ++- .../bpf/test_tcp_check_syncookie_user.c | 4 ++- .../selftests/bpf/test_tcpnotify_user.c | 1 - .../testing/selftests/bpf/test_verifier_log.c | 5 ++-- .../selftests/bpf/xdp_redirect_multi.c | 1 - tools/testing/selftests/bpf/xdping.c | 8 ++---- tools/testing/selftests/bpf/xdpxceiver.c | 6 ++-- 61 files changed, 57 insertions(+), 142 deletions(-) delete mode 100644 tools/testing/selftests/bpf/bpf_rlimit.h -- 2.17.1

[PATCH V3] testing/selftests/mqueue: Fix mq_perf_tests to free the allocated cpu set

by Athira Rajeev

The selftest "mqueue/mq_perf_tests.c" use CPU_ALLOC to allocate CPU set. This cpu set is used further in pthread_attr_setaffinity_np and by pthread_create in the code. But in current code, allocated cpu set is not freed. Fix this issue by adding CPU_FREE in the "shutdown" function which is called in most of the error/exit path for the cleanup. There are few error paths which exit without using shutdown. Add a common goto error path with CPU_FREE for these cases.

[PATCH] kunit: tool: don't print out test statuses w/ 0s in summary

by Daniel Latypov

Before: > Testing complete. Passed: 137, Failed: 0, Crashed: 0, Skipped: 36, Errors: 0 After: > Testing complete. Passed: 137, Skipped: 36 Even with our current set of statuses, the output is a bit verbose. It could get worse in the future if we add more (e.g. timeout, kasan). Let's only print the relevant ones. I had previously been sympathetic to the argument that always printing out all the statuses would make it easier to parse results. But now we have commit acd8e8407b8f ("kunit: Print test statistics on failure"), there are test counts printed out in the raw output. We don't currently print out an overall total across all suites, but it would be easy to add, if we see a need for that.
