We don't have PROG_TEST_RUN support for sk_lookup programs at the moment. So far this hasn't been a problem, since we can run our tests in a separate network namespace. For benchmarking it's nice to have PROG_TEST_RUN, so I've gone and implemented it. Based on discussion on the v1 I've dropped support for testing multiple programs at once. Changes since v3: - Use bpf_test_timer prefix (Andrii) Changes since v2: - Fix test_verifier failure (Alexei) Changes since v1: - Add sparse annotations to the t_* functions - Add appropriate type casts in bpf_prog_test_run_sk_lookup - Drop running multiple programs Lorenz Bauer (5): bpf: consolidate shared test timing code bpf: add PROG_TEST_RUN support for sk_lookup programs selftests: bpf: convert sk_lookup ctx access tests to PROG_TEST_RUN selftests: bpf: check that PROG_TEST_RUN repeats as requested selftests: bpf: don't run sk_lookup in verifier tests include/linux/bpf.h | 10 + include/uapi/linux/bpf.h | 5 +- net/bpf/test_run.c | 246 +++++++++++++----- net/core/filter.c | 1 + tools/include/uapi/linux/bpf.h | 5 +- .../selftests/bpf/prog_tests/prog_run_xattr.c | 51 +++- .../selftests/bpf/prog_tests/sk_lookup.c | 83 ++++-- .../selftests/bpf/progs/test_sk_lookup.c | 62 +++-- tools/testing/selftests/bpf/test_verifier.c | 4 +- .../selftests/bpf/verifier/ctx_sk_lookup.c | 1 + 10 files changed, 356 insertions(+), 112 deletions(-) -- 2.27.0
