i have checked first ticket - 51593 and it is modified in below commit 60dd5188871eb2589ba000368e5cb0c05d27f89b. In this function icmp_send_response , iphdr->src is should be the destination address for response and iphdr->dest will be the source. ip4_route_src parameter may go wrong in this case because in ip4_route_src the destination will become source and source will become destination. please check once.
