2022-09-02selftests/bpf: Store BPF object files with .bpf.o extensionDaniel Müller1-1/+1
BPF object files are, in a way, the final artifact produced as part of the ahead-of-time compilation process. That makes them somewhat special compared to "regular" object files, which are a intermediate build artifacts that can typically be removed safely. As such, it can make sense to name them differently to make it easier to spot this difference at a glance. Among others, libbpf-bootstrap [0] has established the extension .bpf.o for BPF object files. It seems reasonable to follow this example and establish the same denomination for selftest build artifacts. To that end, this change adjusts the corresponding part of the build system and the test programs loading BPF object files to work with .bpf.o files.

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()`.
