@sc07kvm thanks for this contribution. I just put this in my stash for later review. |

Run method is used to load and run the BPF program without attaching it to any hook. This is useful for testing the BPF program. It makes use of the bpf(BPF_PROG_TEST_RUN) via bpf_prog_test_run_opts(). The prog-run selftest is added to test the Run method. More examples can be found in the linux kernel source code: tools/testing/selftests/bpf/prog_tests. Original code aquasecurity#428 was authored by sc07kvm, and this commiter have only made cosmetics adjustments. Co-authored-by: Geyslan Gregório <[email protected]>

The written code passes a bpf_prog_test_run_opts from libbpf. This is a good feature for writing tests on eBPF code.
