Some ipv6 protocols cannot handle ipv4 addresses, so we must not allow connecting and binding to them. sendmsg logic does already check msg->name for this but must trust already connected sockets which could be set up for connection to ipv4 address family. Per-socket flag ipv6only is of no use here, as it is under users control by setsockopt. Signed-off-by: Hannes Frederic Sowa <[email protected]> Signed-off-by: David S. Miller <[email protected]>
