[Linux-stable-mirror] Patch "ipip: only increase err_count for some certain type icmp in ipip_err" has been added to the 4.13-stable tree

This is a note to let you know that I've just added the patch titled ipip: only increase err_count for some certain type icmp in ipip_err to the 4.13-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: ipip-only-increase-err_count-for-some-certain-type-icmp-in-ipip_err.patch and it can be found in the queue-4.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Wed Nov 15 17:25:34 CET 2017 From: Xin Long <lucien.xin(a)gmail.com> Date: Thu, 26 Oct 2017 19:19:56 +0800 Subject: ipip: only increase err_count for some certain type icmp in ipip_err From: Xin Long <lucien.xin(a)gmail.com> [ Upstream commit f3594f0a7ea36661d7fd942facd7f31a64245f1a ] t->err_count is used to count the link failure on tunnel and an err will be reported to user socket in tx path if t->err_count is not 0. udp socket could even return EHOSTUNREACH to users. Since commit fd58156e456d ("IPIP: Use ip-tunneling code.") removed the 'switch check' for icmp type in ipip_err(), err_count would be increased by the icmp packet with ICMP_EXC_FRAGTIME code. an link failure would be reported out due to this. In Jianlin's case, when receiving ICMP_EXC_FRAGTIME a icmp packet, udp netperf failed with the err: send_data: data send error: No route to host (errno 113) We expect this error reported from tunnel to socket when receiving some certain type icmp, but not ICMP_EXC_FRAGTIME, ICMP_SR_FAILED or ICMP_PARAMETERPROB ones. This patch is to bring 'switch check' for icmp type back to ipip_err so that it only reports link failure for the right type icmp, just as in ipgre_err() and ipip6_err().

As a result we may now have a blackhole route cached at a socket on some IPsec scenarios. This makes the connection unusable.

[Linux-stable-mirror] Patch "ip6_gre: update dst pmtu if dev mtu has been updated by toobig in __gre6_xmit" has been added to the 4.13-stable tree

For skb_dst(skb)'s pmtu may still be using the old value, it has no chance to be updated with tunnel dev's mtu. Jianlin found this issue by reducing route's mtu while running netperf, the performance went to 0. ip6ip6 and ip4ip6 tunnel can work well with this, as they lookup the upper dst and update_pmtu it's pmtu or icmpv6_send a Toobig to upper socket after setting tunnel dev's mtu. We couldn't do that for ip6_gre, as gre's inner packet could be any protocol, it's difficult to handle them (like lookup upper dst) in a good way. So this patch is to fix it by updating skb_dst(skb)'s pmtu when dev->mtu < skb_dst(skb)'s pmtu in tx path. It's safe to do this update there, as usually dev->mtu <= skb_dst(skb)'s pmtu and no performance regression can be caused by this.
