Subject: [PATCH net-next 0/2] bpf: performance improvements
Date: Tue, 15 Sep 2015 18:51:33 -0700	[thread overview]
Message-ID: <1442368295-5204-1-git-send-email-ast@plumgrid.com> (raw)

At plumbers we discussed different options on how to get rid of skb_clone
from bpf_clone_redirect(), the patch 2 implements the best option.
Patch 1 adds 'integrated exts' to cls_bpf to improve performance by
combining simple actions into bpf classifier.

Alexei Starovoitov (1):
  bpf: add bpf_redirect() helper

Daniel Borkmann (1):
  cls_bpf: introduce integrated actions
