Subject: Re: Kernel Self Protection Project

Excellent initiative!

FYI, you can find the grsecurity patches automatically integrated in a consistent Git repository: . I took all patches I could find (with their signatures and changelogs!), starting from the beginning of the Linux Git history (2005: v2.6.14.2), and applying them following branches and merges. The result is quite interesting and help to dive into the Linux/grsecurity internals (with log, blame and bisect). Moreover, it show the work of Brad Spengler backporting fixes.
I did the same with PaX but it needs some more work before going public.
