2021-12-14selftests/bpf: Stop using bpf_object__find_program_by_title API.Kui-Feng Lee1-2/+2
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.

2021-11-07selftests/bpf: Use explicit bpf_prog_test_load() calls everywhereAndrii Nakryiko1-1/+1
-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.

2019-08-28selftests/bpf: test_progs: remove global fail/success countsStanislav Fomichev1-2/+1
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.

2019-07-27selftests/bpf: abstract away test log outputAndrii Nakryiko1-3/+3
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()`.
