- Pin trivial bpf programs to bpf filesystem, compose BPFProgram= option
string and pass it to a unit. Programs store `0` in r0 BPF register for
denying action, e.g. drop a packet.
- Load trivial BPF programs
- Test is skipped if not run under root or if can not lock enough
memory.
- For egress and ingress hooks, test BPFProgram= option along with
with IP{Egress|Ingress}FilterPath=, expected result should not depend on
which rule is executed first.
Expected results for BPF_CGROUP_INET_INGRESS:
5 packets transmitted, 0 received, 100% packet loss, time 89ms
For BPF_CGROUP_INET_SOCK_CREATE:
ping: socket: Operation not permitted
