Changes v1 -> v2:
1. Updated the list of read-only fields, and read-write fields.
2. Added dummy sk to bpf_prog_test_run_skb().

This set enables BPF program of type BPF_PROG_TYPE_CGROUP_SKB to access
some __skb_buff data directly.

Song Liu (2):
  bpf: add cg_skb_is_valid_access for BPF_PROG_TYPE_CGROUP_SKB
  bpf: add tests for direct packet access from CGROUP_SKB
