某种意义上说，eBPF正朝着一个完备的内核态可编程接口快速进化。

I found it very confusing that a program named xdpdump will use the tcpdump hook to dump packets, when there isn't any other XDP-prog already attached on the interfaces. I do like that the xdpdump program warns the end-user about this be...
trace_xdp_exception(rq->netdev, prog, act); fallthrough; caseXDP_DROP: rq->stats->xdp_drop++; returntrue; } } bpf_prog_run_xdp 就是真实运行 XDP 程序的函数。 XDP_PASS on Mellanox 如果XDP 程序里 XDP_PASS 该网络包到内核,Mellanox 网卡驱动还做了哪些处理呢?
