Subject: [PATCH bpf 0/4] Various fixes for sockmap and reuseport tests
Date: Thu, 23 Jan 2020 16:59:29 +0000	[thread overview]
Message-ID: <20200123165934.9584-1-lmb@cloudflare.com> (raw)

I noticed some rough edges while running the sockmap and reuseport tests in
a virtme environment. It only has a single CPU, and the root filesystem is
mounted read-only.

The cause for patch #2 is either the VM being slow because it only has a
single CPU. Patches #3-4 helped me narrow down the problem, so they are
probably useful for others as well.

Lorenz Bauer (4):
  selftests: bpf: use a temporary file in test_sockmap
  selftests: bpf: ignore RST packets for reuseport tests
  selftests: bpf: make reuseport test output more legible
  selftests: bpf: reset global state between reuseport test runs
