From 351c1e648623b742fe1687636117306adc8b561c Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 4 Mar 2016 15:56:06 +0000 Subject: rxrpc: Be more selective about the types of received packets we accept Currently, received RxRPC packets outside the range 1-13 are rejected. There are, however, holes in the range that should also be rejected - plus at least one type we don't yet support - so reject these also.
