Subject: [PATCH v2 bpf-next 0/2] bpf: add cg_skb_is_valid_access
Date: Wed, 17 Oct 2018 16:36:14 -0700 [thread overview]
Message-ID: <20181017233616.3130909-1-songliubraving@fb.com> (raw)
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
