This patch attaches a classifier prog to the ingress filter.
It exercises the following helpers with different socket pointer
types in different logical branches:
1. bpf_sk_release()
2. bpf_sk_assign()
3. bpf_skc_to_tcp_request_sock(), bpf_skc_to_tcp_sock()
4. bpf_tcp_gen_syncookie, bpf_tcp_check_s
