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 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 for_each_bpf_prog helper 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 include/linux/bpf.h | 21 +- include/linux/filter.h | 4 +- include/uapi/linux/bpf.h | 5 +- net/bpf/test_run.c | 245 +++++++++++++----- 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 +++-- 9 files changed, 358 insertions(+), 119 deletions(-) -- 2.27.0
