Date: Wed, 26 Apr 2017 23:24:47 -0700 From: Martin KaFai Lau <kafai@...com> To: <netdev@...r.kernel.org> CC: Daniel Borkmann <daniel@...earbox.net>, Hannes Frederic Sowa <hannes@...essinduktion.org>, Alexei Starovoitov <ast@...com>, <kernel-team@...com> Subject: [RFC net-next 0/2] Introduce bpf_prog ID and iteration This patchset introduces the bpf_prog ID and a new bpf cmd to iterate all bpf_prog in the system. It is still incomplete. The idea can be extended to bpf_map.
