Subject: [bpf-next PATCH 0/3] sockmap support for msg_peek flag

This adds support for the MSG_PEEK flag when redirecting into an
ingress psock sk_msg queue.

The first patch adds some base support to the helpers, then the
feature, and finally we add an option for the test suite to do
a duplicate MSG_PEEK call on every recv to test the feature.

With duplicate MSG_PEEK call all tests continue to PASS.

John Fastabend (3):
      bpf: skmsg, improve sk_msg_used_element to work in cork context
      bpf: sockmap, support for msg_peek in sk_msg with redirect ingress
      bpf: sockmap, add msg_peek tests to test_sockmap
