SUNRPC: Replace svc_addr_u by sockaddr_storage
For IPv6 local address, lockd can not callback to client for missing scope id when binding address at inet6_bind: 324 if (addr_type & IPV6_ADDR_LINKLOCAL) { 325 if (addr_len >= sizeof(struct sockaddr_in6) && 326 addr->sin6_scope_id) { 327 /* Override any existing binding, if another one 328 * is supplied by user. 329 */ 330 sk->sk_bound_dev_if = addr->sin6_scope_id; 331 } 332 333 /* Binding to link-local address requires an interface */ 334 if (!sk->sk_bound_dev_if) { 335 err = -EINVAL; 336 goto out_unlock; 337 } Replacing svc_addr_u by sockaddr_storage, let rqstp->rq_daddr contains more info besides address.
