Dev Communityvia NewsData.io
eBPF (Extended Berkeley Packet Filter) is a powerful network and performance analysis tool on the Linux kernel. It allows developers to dynamically load, update, and run user-defined code at runtime. This article is the second part of the eBPF Tutorial by Example, focusing on using kprobe to capture the unlink system call in eBPF. The article will first explain the basic concepts and technical background of kprobes, and then introduce how to use kprobe to capture the unlink system call in eBPF. Background of kprobes Technology During the debugging process of the kernel or modules, developers o
