xdp-tutorial VS bpf-developer-tutorial

You're probably interested in https://github.com/xdp-project/xdp-tools and https://github.com/xdp-project/xdp-tutorial. BPF programs are (usually) written in a restricted subset of C, it's not really as simple as nft add rule inet filter input tcp dport 80 accept.

xdp-tutorial is heavily outdated, and doesn't use the current headers and neither the current libbpf.

Through this article, readers can gain a deep understanding of how to use eBPF technology for tracing seven-layer protocols, particularly HTTP traffic. This knowledge will help enhance the monitoring and analysis of network traffic, thereby improving application performance and security. If you're interested in learning more about eBPF and its practical applications, you can visit our tutorial code repository at https://github.com/eunomia-bpf/bpf-developer-tutorial or our website at https://eunomia.dev/tutorials/ for more examples and complete tutorials.
