Hi, Michal, Could you help to test my updated patches? You can find them (the most top 4 patches) in my github tree: https://github.com/congwang/linux/commits/ipv6 which is based on net-next. I tried to setup the environment to reproduce it, but failed. I also tried scapy, but I still can't trigger "Fragment Reassembly Timeout". Thanks a lot! -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
