Cover letter [PATCHv2 net-next 0/3] sctp: add support for sk_reuseport
sctp sk_reuseport allows multiple socks to listen on the same port and addresses, as long as these socks have the same uid. This works pretty much as TCP/UDP does, the only difference is that sctp is multi-homing and all the bind_addrs in these socks will have to completely matched, otherwise listen() will return err.
The below is when 5 sockets are listening on 172.16.254.254:6400 on a server, 26 sockets on a client connect to 172.16.254.254:6400 and each may be processed by a different socket on the server which is selected by hash(lport, pport, paddr) in reuseport_select_sock():
