That&rsquo;s eBPF.</p> <p>This post is a practical intro. I&rsquo;ll cover how eBPF programs actually work, walk through a real example, explain the two ways to get data out of the kernel, and show how the userspace side ties it all together. At the end I&rsquo;ll touch on the network security toolkit I&rsquo;ve been building on top of this.</p>
