Which kernel version did you test this on?

Thanks,
Hannes

I think it is all version

I wonder very much because in tests I definitely hit the

static void __ip6_rt_update_pmtu(struct dst_entry *dst, const struct
sock *sk,
				 const struct ipv6hdr *iph, u32 mtu)
{
	struct rt6_info *rt6 = (struct rt6_info *)dst;

	if (rt6->rt6i_flags & RTF_LOCAL)
		return;

RTF_LOCAL check all the times. Which kernel version did you on
specifically?

Thanks,
Hannes
