From 652d068119052b0b3bc4a0808a4400a22380a30b Mon Sep 17 00:00:00 2001 From: Andrei Vagin Date: Fri, 28 Dec 2018 11:26:01 -0800 Subject: Implement SO_REUSEPORT for TCP and UDP sockets This option allows multiple sockets to be bound to the same port. Incoming packets are distributed to sockets using a hash based on source and destination addresses. This means that all packets from one sender will be received by the same server socket.
