Woah, that describes the userspace side of AA just fine, it means

nothing when it comes to the in-kernel implementation.  There is no

reason that you can't implement the same functionality using some

totally different in-kernel solution if possible.

I am still not completely certian that we can not properly implement AA

functionality using a SELinux backend solution.  Yes, the current tools

that try to implement this are still lacking, and maybe the kernel needs

to change, but that is possible.
I still want to see a definition of the AA "model" that we can then use

to try to implement using whatever solution works best.  As that seems

to be missing the current argument of if AA can or can not be

implemented using SELinux or something totally different should be

stopped.
So, AA developers, do you have such a document anywhere?  I know there

are some old research papers, do they properly describe the current

model you are trying to implement here?
thanks,
