Subject: [PATCH bpf-next v3 0/5] PROG_TEST_RUN support for sk_lookup programs
Date: Mon, 1 Mar 2021 10:18:54 +0000 [thread overview]
Message-ID: <20210301101859.46045-1-lmb@cloudflare.com> (raw)
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 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
