rxrpc: Provide a way for AFS to ask for the peer address of a call
Provide a function so that kernel users, such as AFS, can ask for the peer address of a call: void rxrpc_kernel_get_peer(struct rxrpc_call *call, struct sockaddr_rxrpc *_srx); In the future the kernel service won't get sk_buffs to look inside. Further, this allows us to hide any canonicalisation inside AF_RXRPC for when IPv6 support is added. Also propagate this through to afs_find_server() and issue a warning if we can't handle the address family yet. Signed-off-by: David Howells <dhowells@redhat.com>
