[PATCH bpf-next v2 0/5] PROG_TEST_RUN support for sk_lookup programs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
