Subject: [bpf-next PATCH 6/7] bpf: sockmap put client sockets in blocking mode
Date: Mon, 08 Jan 2018 10:06:31 -0800 [thread overview]
Message-ID: <20180108180631.13647.7114.stgit@john-Precision-Tower-5810> (raw)
In-Reply-To: <20180108180302.13647.13866.stgit@john-Precision-Tower-5810>
Put client sockets in blocking mode otherwise with sendmsg tests
its easy to overrun the socket buffers which results in the test
being aborted.
The original non-blocking was added to handle listen/accept with
a single thread the client/accepted sockets do not need to be
non-blocking.
