This project starts with the premise that [https://lwn.net/Articles/410606/ kernel bugs have a very long lifetime], and that the kernel must be designed in ways to protect against these flaws. We must think of [http://lwn.net/Articles/662219/ security beyond fixing bugs]. As a community, we already find and fix individual bugs via static checkers (compiler flags, [http://smatch.sourceforge.net/ smatch], [http://coccinelle.lip6.fr/ coccinelle], [https://scan.coverity.com/projects/linux?tab=overview coverity]) and dynamic checkers (kernel configs, [http://codemonkey.org.uk/projects/trinity/ trinity], [https://www.kernel.org/doc/Documentation/kasan.txt KASan]). Those efforts are important and on-going, but if we want to protect our [http://www.techspot.com/news/57228-google-shows-off-new-version-of-android-announces-1-billion-active-monthly-users.html billion Android phones], our [http://www.zdnet.com/article/2014-the-year-of-the-linux-car/ cars], the [https://training.linuxfoundation.org/why-our-linux-training/training-reviews/linux-foundation-training-prepares-the-international-space-station-for-linux-migration International Space Station], and everything else running Linux, we must get proactive defensive technologies built into the upstream Linux kernel. We need the kernel to [http://kernsec.org/files/lss2015/giant-bags-of-mostly-water.pdf fail safely, instead of just running safely].
 
These kinds of protections have existed for years in [https://pax.grsecurity.net/ PaX], [https://grsecurity.net/features.php grsecurity], and piles of academic papers. For various social, cultural, and technical reasons, they have not made their way into the upstream kernel, and this project seeks to change that. Our focus is on kernel self-protection, rather than kernel-supported userspace protections. The goal is to eliminate both classes of bugs and methods of exploitation.
 
= Get Involved =
 
Want to get involved? [http://www.openwall.com/lists/#subscribe Join] the [http://www.openwall.com/lists/kernel-hardening/ kernel hardening mailing list] and introduce yourself. Then pick an area of work from below (or add a new one), coordinate on the mailing list, and get started. If your employer is brave enough to understand how critical this work is, they'll pay you to work on it. If not, the [http://www.linuxfoundation.org/ Linux Foundation]'s [https://www.coreinfrastructure.org/faq Core Infrastructure Initiative] is in a great position to fund specific work proposals. We need kernel developers, compiler developers, testers, backporters, a documentation writers.
