The discussion among developers about kernel hardening is getting more concrete. Kees Cook has founded the Kernel Self Protection Project. On the recent Kernel Summit in Seoul he had invited other developers to join his initiative in order to implement pro-active measures to make the kernel more secure. He specifically mentions self-protection technologies found in PaX and Grsecurity. In a newly created wiki he has already presented several work areas (bug classes, exploitation methods) as a starting point for the project. Let's hope that this project will get a lot of support. I think chances are good as Kees is not someone or other.
The Washington Post article, mentioned by Kees Cook on the LWN.net page, is a really interesting food-for-thought piece. Interviews with Linus Torvalds, Kees Cook and Brad Spengler on the (level of) importance of adding security features to the kernel. hxxp://www.washingtonpost.com/sf/business/2015/11/05/net-of-insecurity-the-kernel-of-the-argument/
