* svc: Avoid garbage replies when pc_func() returns rpc_drop_replyChuck Lever2017-04-111-1/+2
| | | | | | | | | | | | | | | commit 0533b13072f4bf35738290d2cf9e299c7bc6c42a upstream. If an RPC program does not set vs_dispatch and pc_func() returns rpc_drop_reply, the server sends a reply anyway containing a single word containing the value RPC_DROP_REPLY (in network byte-order, of course). This is a nonsense RPC message.

* NFS: Don't drop CB requests with invalid principalsChuck Lever2017-04-111-0/+5
| | | | | | | | | | | | | | | | | commit a4e187d83d88eeaba6252aac0a2ffe5eaa73a818 upstream. Before commit 778be232a207 ("NFS do not find client in NFSv4 pg_authenticate"), the Linux callback server replied with RPC_AUTH_ERROR / RPC_AUTH_BADCRED, instead of dropping the CB request. Let's restore that behavior so the server has a chance to do something useful about it, and provide a warning that helps admins correct the problem.
