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.

2022-02-02selftests/bpf: Migrate from bpf_prog_test_runDelyan Kratunov1-8/+11
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.

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.

2019-12-13selftests: bpf: Add xdp_perf testBjörn Töpel1-0/+25
The xdp_perf is a dummy XDP test, only used to measure the the cost of jumping into a naive XDP program one million times. To build and run the program: $ cd tools/testing/selftests/bpf $ make $ ./test_progs -v -t xdp_perf Signed-off-by: Björn Töpel <[email protected]> Signed-off-by: Alexei Starovoitov <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
