Currently, on multihomed host, when chrony is not bound to a specific IP address, a query is sent to an interface and the default source IP hint for the back route differs, the reply will have a source IP different than where the query was destinied to. This will cause problems because connection tracking firewalls will drop the replies and most likely the client program will get confused too. This patch uses the IP_PKTINFO mechanism to get the IP address where received packets where targetted to and use that IP address as source hint when sending a reply.
