Undo rm: Hacking the filesystem - Jessica Yu, Red Hat

Sign up or log in to save this to your schedule and see who's attending!

You're probably familiar with this dreaded scenario when you first started out using Linux: accidentally removing an important file with the rm command. And of course, there's no recycling bin! In this talk I'll share with you one of my first kernel hacks - implementing an undo rm "unrm" operation in the Linux kernel. This talk aims to be a gentle introduction to kernel development, in the form of a project show-and-tell. We'll start our trace of a typical unrm call from userspace and make our way down to Linux's VFS layer. In the process, I'll show you what a typical kernel debugging session might look like, and how you might make changes and run your kernel. In the end we'll put these concepts together and demo unrm's functionality.
