selftests/bpf: Convert some selftests to high-level BPF map APIs Convert a bunch of selftests to using newly added high-level BPF map APIs. This change exposed that map_kptr selftests allocated too big buffer, which is fixed in this patch as well.

selftests/bpf: Fix spurious test failures in core_retro selftest core_retro selftest uses BPF program that's triggered on sys_enter system-wide, but has no protection from some unrelated process doing syscall while selftest is running. This leads to occasional test failures with unexpected PIDs being returned. Fix that by filtering out all processes that are not test_progs process.

selftests/bpf: Add test relying only on CO-RE and no recent kernel features Add a test that relies on CO-RE, but doesn't expect any of the recent features, not available on old kernels. This is useful for Travis CI tests running against very old kernels (e.g., libbpf has 4.9 kernel testing now), to verify that CO-RE still works, even if kernel itself doesn't support BTF yet, as long as there is .BTF embedded into vmlinux image by pahole. Given most of CO-RE doesn't require any kernel awareness of BTF, it is a useful test to validate that libbpf's BTF sanitization is working well even with ancient kernels.
