I’m really happy to share that I will be traveling to Paris to speak at Kernel Recipes in the week after the Open Source Summit Europe. ✈️🇨🇵🗣️🎙️ This will be my 6th consecutive edition speaking at one of the most unique Linux kernel conferences. I’m really excited about this opportunity, and as always, feel free to say hi if you see me around. 🙂👋🏽
My talk will cover the work I’ve been doing in the Kernel Self-Protection Project over the last few months to fix thousands of -Wflex-array-member-not-at-end warnings. It can also be considered a sequel to my presentation last year, where I introduced this GCC compiler option to the audience:

Enhancing spatial safety: Fixing thousands of -Wflex-array-member-not-at-end warnings
https://kernel-recipes.org/en/2024/enhancing-spatial-safety-fixing-thousands-of-wflex-array-member-not-at-end-warnings/
The introduction of the new -Wflex-array-member-not-at-end compiler option, released in GCC-14, has revealed approximately 60,000 warnings in the Linux kernel. Among them, some legitimate bugs have been uncovered.
In this presentation, we will explore in detail the different strategies we are employing to resolve all these warnings. These methods have already helped us resolve about 30% of them. Our ultimate goal in the Kernel Self-Protection Project is to globally enable this option in mainline, further enhancing the security of the kernel in the spatial safety domain.
By the way, I’m currently writing a detailed blog post about this work. Stay tuned! 📝
