[PATCH net-next 0/3] bpf improvements

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
