From cd5892c756f51ed6ff18ff49c837d219bfd9bb5d Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 13 Sep 2016 08:49:05 +0100 Subject: rxrpc: Create an address for sendmsg() to bind unbound socket with Create an address for sendmsg() to bind unbound socket with rather than using a completely blank address otherwise the transport socket creation will fail because it will try to use address family 0. We use the address family specified in the protocol argument when the AF_RXRPC socket was created and SOCK_DGRAM as the default. For anything else, bind() must be used.

With this, AF_RXRPC sockets can be created: service = socket(AF_RXRPC, SOCK_DGRAM, PF_INET6); instead of: service = socket(AF_RXRPC, SOCK_DGRAM, PF_INET); The AFS filesystem doesn't support IPv6 at the moment, though, since that requires upgrades to some of the RPC calls. Note that a good portion of this patch is replacing "%pI4:%u" in print statements with "%pISpc" which is able to handle both protocols and print the port.
