# \[bpf-next PATCH 6/7\] bpf: sockmap put client sockets in blocking mode - From: John Fastabend \ - Date: 2018-01-08 18:06:42 - List: netdev - Page: https://ratatoskr.run/netdev/2018/01/11079458 - Thread: https://ratatoskr.run/netdev/2018/01/11079452/t.md ```text 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.
