ipv6: unshare inetpeers
We currently cow metrics a bit too soon in IPv6 case : All routes are tied to a single inetpeer entry. Change ip6_rt_copy() to get destination address as second argument, so that we fill rt6i_dst before the dst_copy_metrics() call. icmp6_dst_alloc() must set rt6i_dst before calling dst_metric_set(), or else the cow is done while rt6i_dst is still NULL. If orig route points to readonly metrics, we can share the pointer instead of performing the memory allocation and copy. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
