It's been a long time since I updated my repository with a recent kernel version, sorry for that. This is now done, the kernel (sources, i386 and amd64) is based on the (yet unreleased) 3.2.68-1 Debian kernel, patched with grsecurity 3.1-3.2.68-201503251805, and has the version 3.2.68-1~grsec1.

It works fine here, but as always, no warranty. If any problem occurs, try to reproduce using vanilla 3.2.68 + grsec patch before reporting here.

And now that Jessie release approaches, the question of what to do with those Debian/grsec kernel still arrise: the Jessie kernel is based on the 3.16 branch, which is not a (kernel.org) long term branch. Actually, the support already ended some times ago, and the (long term) maintainance is now assured by the Canonical Kernel Team (thus the -ckt suffix) with some help from the Debian kernel maintainers. So there's no Grsecurity patch following 3.16, and there's no easy way to forward-port the 3.14 patches.

At that point, and considering the support I got the last few years on this initiative, I don't think it's really worth it to continue providing those kernels.

One initiative which might be interesting, though, is the Mempo kernels. The Mempo team works on kernel reproducible builds, but they also include the grsecurity patch. Unfortunately, it seems that building the kernel their way involves calling a bash script which calls another one, and another one. A quick look at the various repositories is only enough to confuse me about how actually they build the kernel, in the end, so I'm unsure it's the perfect fit for a supposedly secure kernel. Not that the Debian way of building the kernel doesn't involves calling a lot of scripts (either bash or python), but still. After digging a bit, it seems that they're using make-kpkg (from the kernel-package package), which is not the recommended way anymore. Also, they're currently targeting Wheezy, so the 3.2 kernel, and I have no idea what they'll chose for Jessie.

In the end, for myself, I might just do a quick script which takes a git repository at the right version, pick the latest grsec patch for that branch, applies it, then run make deb-pkg and be done with it. That still leaves the problem of which branch to follow:

• run a 3.14 kernel instead of the 3.16 (I'm unsure how much I'd lose / not gain from going to 3.2 to 3.14 instead of 3.16);
• run a 3.19 kernel, then upgrade when it's time, until a new LTS branch appears.

There's also the config file question, but if I'm just using the kernels for myself and not sharing them, it's also easier, although if some people are actually interested it's not hard to publish them.
