selftests/bpf: Migrate from bpf_prog_test_run

2022-02-03T06:31:18Z

bpf_prog_test_run is being deprecated in favor of the OPTS-based bpf_prog_test_run_opts. We end up unable to use CHECK in most cases, so replace usages with ASSERT_* calls.

selftests/bpf: Initialize duration in xdp_noinline.c

2020-10-02T14:46:20Z

Fixes clang error: tools/testing/selftests/bpf/prog_tests/xdp_noinline.c:35:6: error: variable 'duration' is uninitialized when used here [-Werror,-Wuninitialized] if (CHECK(!skel, "skel_open_and_load", "failed\n")) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Stanislav Fomichev Signed-off-by: Daniel Borkmann Acked-by: Martin KaFai Lau Link: https://lore.kernel.org/bpf/20201001225440.1373233-1-sdf@google.com

selftests/bpf: Modernize xdp_noinline test w/ skeleton and __noinline

2020-09-04T00:14:40Z

Update xdp_noinline to use BPF skeleton and force __noinline on helper sub-programs. Also, split existing logic into v4- and v6-only to complicate sub-program calling patterns (partially overlapped sets of functions for entry-level BPF programs).

selftests/bpf: Move existing common networking parts into network_helpers

2020-05-08T22:48:20Z

1. Move pkt_v4 and pkt_v6 into network_helpers and adjust the users. 2. Copy-paste spin_lock_thread into two tests that use it.

selftests/bpf: test_progs: remove global fail/success counts

2019-08-27T22:35:40Z

Now that we have a global per-test/per-environment state, there is no longer need to have global fail/success counters (and there is no need to save/get the diff before/after the test). Introduce CHECK_FAIL macro (suggested by Andrii) and covert existing tests to it. CHECK_FAIL uses new test__fail() to record the failure.

selftests/bpf: test_progs: test__printf -> printf

2019-08-07T00:17:52Z

Now that test__printf is a simple wraper around printf, let's drop it (and test__vprintf as well). Cc: Andrii Nakryiko Acked-by: Andrii Nakryiko Signed-off-by: Stanislav Fomichev Signed-off-by: Alexei Starovoitov

selftests/bpf: abstract away test log output

2019-07-28T05:36:19Z

This patch changes how test output is printed out. By default, if test had no errors, the only output will be a single line with test number, name, and verdict at the end, e.g.: #31 xdp:OK If test had any errors, all log output captured during test execution will be output after test completes. It's possible to force output of log with `-v` (`--verbose`) option, in which case output won't be buffered and will be output immediately. To support this, individual tests are required to use helper methods for logging: `test__printf()` and `test__vprintf()`. Signed-off-by: Andrii Nakryiko Signed-off-by: Alexei Starovoitov
