====================
rxrpc: Fixes
Here are a couple of bugfixes plus a patch that makes one of the bugfixes
easier:
(1) Move the ping and mutex unlock on a new call from rxrpc_input_packet()
into rxrpc_new_incoming_call(), which it calls. This means the
lock-unlock section is entirely within the latter function. This
simplifies patch (2).
(2) Don't take the call->user_mutex at all in the softirq path. Mutexes
aren't allowed to be taken or released there and a patch was merged
that caused a warning to be emitted every time this happened. Looking
at the code again, it looks like that taking the mutex isn't actually
necessary, as the value of call->state will block access to the call.
(3) Fix the incoming call path to check incoming calls earlier to reject
calls to RPC services for which we don't have a security key of the
appropriate class. This avoids an assertion failure if YFS tries
making a secure call to the kafs cache manager RPC service.
