XDP应用最后通常是将执行的动作保存在 r0 寄存器,然后再退出。 例如 r0=1;exit; 这可以优化成一条 exit_drop 测试结果 作者选取了几个在 Linux 代码库中的XDPexample ,一个简单的XDP防火墙和 Facebook 开源的 36420 eBPF文章翻译(3)——XDP原始设计介绍...

A race condition in the virtual ethernet driver of the Linux kernel led to occasional packet content corruptions, which resulted in unwanted packet drops by one of our DDoS mitigation systems. This blogpost describes the thought process and technique we
