Subject: [bpf-next PATCH 0/3] sockmap support for msg_peek flag
Date: Tue, 16 Oct 2018 11:07:54 -0700 [thread overview]
Message-ID: <20181016180424.13607.7932.stgit@john-Precision-Tower-5810> (raw)
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.
