selftests/bpf: Stop using bpf_object__find_program_by_title API.

2021-12-14T22:38:05Z

bpf_object__find_program_by_title is going to be deprecated. Replace all use cases in tools/testing/selftests/bpf with bpf_object__find_program_by_name or bpf_object__for_each_program.

selftests/bpf: Use explicit bpf_prog_test_load() calls everywhere

2021-11-07T16:34:23Z

-Dbpf_prog_load_deprecated=bpf_prog_test_load trick is both ugly and breaks when deprecation goes into effect due to macro magic. Convert all the uses to explicit bpf_prog_test_load() calls which avoid deprecation errors and makes everything less magical.

selftests/bpf: Turn on libbpf 1.0 mode and fix all IS_ERR checks

2021-05-26T00:32:35Z

Turn ony libbpf 1.0 mode. Fix all the explicit IS_ERR checks that now will be broken because libbpf returns NULL on error (and sets errno). Fix ASSERT_OK_PTR and ASSERT_ERR_PTR to work for both old mode and new modes and use them throughout selftests. This is trivial to do by using libbpf_get_error() API that all libbpf users are supposed to use, instead of IS_ERR checks. A bunch of checks also did explicit -1 comparison for various fd-returning APIs. Such checks are replaced with >= 0 or < 0 cases. There were also few misuses of bpf_object__find_map_by_name() in test_maps. Those are fixed in this patch as well.

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.
