Martin KaFai Lau edc2d66ad1 bpf: selftest: Use bpf_skc_to_tcp_sock() in the sock_fields test ... This test uses bpf_skc_to_tcp_sock() to get a kernel tcp_sock ptr "ktp". Access the ktp->lsndtime and also pass ktp to bpf_sk_storage_get(). It also exercises the bpf_sk_cgroup_id() and bpf_sk_ancestor_cgroup_id() with the "ktp". To do that, a parent cgroup and a child cgroup are created. The bpf prog is attached to the child cgroup.
