eBPF Networking Deep Dive: From XDP Packet Processing to TCP Tracing and Production Deployment

Comprehensive deep-dive into eBPF networking internals: XDP packet processing at driver level, Traffic Control subsystem, socket-level tracing with kprobes, TCP state machine and retransmission analysis, DNS query monitoring, network latency distribution and throughput measurement, production deployment guide with kernel configuration, containerized environments, and performance optimization strategies.

Linux 内核网络栈深度实战:从 Socket 系统调用到 NIC 驱动的数据包旅程

Linux 内核网络栈完全实战指南:从一次 write() 系统调用开始,沿着数据的完整旅程——Socket 层、TCP 协议引擎(三次握手、拥塞控制 CUBIC/BBR、延迟确认/Nagle、接收队列)、IP 层路由 FIB Trie 与邻居 ARP 子系统、Qdisc 流量调度 fq_codel/HTB、NIC 驱动与 NAPI 高性能接收、RSS/RPS/RFS 多队列分发,到零拷贝 sendfile/splice/MSG_ZEROCOPY、XDP eBPF 数据面加速、io_uring 异步网络、epoll 高并发与 SO_REUSEPORT 多进程监听。涵盖容器网络调优、TIME_WAIT 优化与生产级抓包分析方法。
