| fix-incorrect-icmpv6-checksum | Dear Guus, I have been using tinc since 2009 and it is great! When PMTUDiscovery=yes and Mode=switch, and if ipv6 is used inside tinc, the ICMPv6 "Packet Too Big" packets have incorrect checksums. It can be reproduced by `ping6 <host in tinc> -s 1800` and `tcpdump -i <tinc interface>`. Consequently, the host ignores the tinc-generated ICMPv6 packets, PMTUDiscovery does not work and the connections freeze when data flows are big. I find the bug is gone if the function "inet_checksum" in route.c is not inlined, either by compiling tinc with "-O2 -fno-inline-functions", or apply a patch such as, diff --git a/src/route.c b/src/route.c index ff82c06e..cd55383a 100644 |
