From d830f0fa1dd7ca447c38aec82cd44230e0b7ca75 Mon Sep 17 00:00:00 2001 From: Phil Oester Date: Thu, 12 Sep 2013 18:04:16 -0700 Subject: netfilter: nf_nat_proto_icmpv6:: fix wrong comparison in icmpv6_manip_pkt In commit 58a317f1 (netfilter: ipv6: add IPv6 NAT support), icmpv6_manip_pkt was added with an incorrect comparison of ICMP codes to types. This causes problems when using NAT rules with the --random option. Correct the comparison. This closes netfilter bugzilla #851, reported by Alexander Neumann.
