selftests/bpf: Replace strncpy() with strscpy()

2026-02-24T16:19:33+00:00

strncpy() does not guarantee NULL-termination and is considered deprecated [1]. Replace strncpy() calls with strscpy().

selftests/bpf: Fix compiler warnings reported in -O2 mode

2023-10-06T18:17:28+00:00

Fix a bunch of potentially unitialized variable usage warnings that are reported by GCC in -O2 mode. Also silence overzealous stringop-truncation class of warnings.

selftests/bpf: Store BPF object files with .bpf.o extension

2022-09-02T13:55:37+00:00

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.

selftests/bpf: Migrate from bpf_prog_test_run

2022-02-03T06:31:18+00:00

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: Use explicit bpf_prog_test_load() calls everywhere

2021-11-07T16:34:23+00:00

-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: test_progs: remove global fail/success counts

2019-08-27T22:35:40+00:00

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.
