Hacking the Linux kernel with Coccinelle Himangi Saraogi, Linux kernel intern, FOSS Outreach Program for Women Round 8 LinuxCon Europe 2014

Introduction ● Computer Science studentm from IIIT- Hyderabad, India currently in my pre-final year. ● Summer Intern for the May-August 2014 round. ● Worked on cleaning up code in the Linux kernel using Coccinelle with Julia Lawall.

How I got Involved ● Linux had been my primary operating system at the university. ● While learning operating systems, I found some exercises to be practiced on the kernel. ● Motivation - Contributing with a great community to impact thousands of users and developers worldwide.

My project Develop/harden coccinelle semantic patches to integrate into the kernel. What Coccinelle can do? ● Static analysis to find patterns in C source code. ● Automatic transformation to fix bugs. ● Generate different information of bugs based on patch notation.

What I did? ● Identify bugs that are prevalent across the kernel. (coccinellery) ● Send patches solving the bug to discuss whether it is an issue of concern. ● Develop coccinelle scripts to fix those bugs. ● Analyze results of the scripts. ● Send patches for the scripts to be accepted into the kernel.
