Where do I get the AppArmor 2.4 compatibility patch?

Question

I just compiled the 2.6.39-rc1 kernel and AppArmor complains about a missing /sys interface (plus, it slows down the boot). Where do I get the AppArmor 2.4 compatibility patch AppArmor asks for?

Solution

There are two ways:

1. You can find the patches for various kernel versions in the kernel-patches directory in the sources of the package apparmor:

    apt-get source apparmor
   

2. You can grab the patches directly from the web (replace precise with whatever version you are running).

The kernel.org link is still down as of now. Ubuntu hosts the patches at bazaar.launchpad.net/~ubuntu-branches/ubuntu/oneiric/apparmo‌​r/…
