everything presented here will work with recent kernels, and this tutorial functions as a self-contained introduction that anyone can go through to learn the XDP basics. Input and contributions to advance towards this goal are very welcome; just open issues or pull requests in theGithub repository...
The ‘test01’ interface visible in the root namespace is the one we will be installing XDP programs on in the tutorial lessons. The XDP program will see packets beingreceivedon this interface; as you can see from the diagram, this means all packets being transmitted from inside the new na...

请根据该网站安装(https://github.com/xdp-project/xdp-tutorial) 注意事项:安装后的libbpf库只存在于xdp-tutorial这个文件夹中,而不存在于系统的/usr/lib或者/usr/include中,如果你想在clion或者vscode中运行或者调试xdp程序是会报错的,因为编译器无法找到libbpf库的位置。个人想到了两种解决办法: ...

$ git clone --recurse-submodules https://github.com/xdp-project/xdp-tutorial.git Finally, we will need a network interface with XDP support to actually load the XDP program onto. XDP support is driver-dependent. As of this writing, it is supported in the Broadcombnxt driver, the Cavium ...
