对Linux协议栈多次perf的结果,我无法忍受conntrack的性能,然而它的功能是如此强大,以至于我无法 对其割舍,我想自己实现一个快速流表,但是我不得不抛弃依赖于conntrack的诸多功能,比如state match,Linux NAT等,诚然,我虽然对NAT也是抱怨太多,但不管怎样,不是还有很多人在用它吗。

kernel: nf_conntrack: table full, dropping packet 【说明】 nf_conntrack 模块在 kernel 2.6.15(2006-01-03 发布) 被引入,工作在 3 层,支持 IPv4 和 IPv6,取代只支持 IPv4 的 ip_connktrack,用于跟踪连接的状态,供其他模块使用,它会使用一个哈希表来记录 established 的记录。需要 NAT 的服务都会用到它...
Introduce changes to add ESP connection tracking helper to netfilter conntrack. The connection tracking of ESP is based on IPsec SPIs. The underlying motivation for this patch was to allow multiple VPN ESP clients to be distinguished when using NAT. Added config flag CONFIG_NF_CT_PROTO_ESP to ...
