From: Alexei Starovoitov <[email-masked]>
Date: Mon, 3 Dec 2018 22:46:03 -0800

Three patches to improve verifier ability to handle pathological bpf programs
with a lot of branches:
- make sure prog_load syscall can be aborted
- improve branch taken analysis
- introduce per-insn complexity limit for unprivileged programs

Alexei Starovoitov (3):
  bpf: check pending signals while verifying programs
  bpf: improve verifier branch analysis
  bpf: add per-insn complexity limit
