From 689f4c646d6a8f0730eec11e06e5909de0b5d5d2 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 30 Jun 2016 11:34:30 +0100 Subject: [PATCH] rxrpc: Check the source of a packet to a client conn When looking up a client connection to which to route a packet, we need to check that the packet came from the correct source so that a peer can't try to muck around with another peer's connection.
