Subject: [PATCH net-next 0/3] bpf improvements
Date: Thu, 11 Aug 2016 18:17:15 -0700 [thread overview]
Message-ID: <1470964638-1313057-1-git-send-email-ast@fb.com> (raw)
Two bpf improvements:
1. allow bpf helpers like bpf_map_lookup_elem() access packet data directly
for XDP programs
2. enable bpf_get_prandom_u32() for tracing programs
Aaron Yue (1):
samples/bpf: add verifier tests for the helper access to the packet
Alexei Starovoitov (2):
bpf: allow helpers access the packet directly
bpf: allow bpf_get_prandom_u32() to be used in tracing
kernel/bpf/verifier.c | 61 +++++++++++++++++-------
kernel/trace/bpf_trace.c | 2 +
samples/bpf/test_verifier.c | 114 ++++++++++++++++++++++++++++++++++++++++++--
