这是构建可移植的预编译 BPF 应用程序的一个关键方面,它不需要将整个 Clang/LLVM 工具链部署到目标系统。另一种方法是在运行时编译 BPF 代码的 BCC 方法,这种方法有很多缺点。 请记住,vmlinux.h不能与其他系统范围内的内核头结合,因为您将不可避免地遇到类型重定义和冲突。所以请坚持只使用vmlinux.h、 libbpf ...
需要在开启了BTF的对应内核版本环境下去运行。 对于4.x版本kernel内核的一些环境,不建议使用CO_RE的一些工具,还是使用bcc工具,安装llvm/clang/bcc来进行相关测试工作。 More:bcc库中libbpf-tools目录下面的libbpf依赖还没更新到支持USDT版本,该目录下面也还没有USDT相关使用的工具。libbpf-bootstrap下面是有USDT的简单示...

Get started with your own BPF application quickly and painlessly with libbpf-bootstrap scaffolding, which takes care of all the mundane setup steps and lets you dive right into BPF fun and minimize the necessary boilerplate. We'll take a look at what lib
