There was a set of LSM hooks proposed for kdbus posted by Karol
Lewandowsk last October, and it also included SELinux and Smack patches.
They were going to be refreshed based on the latest code changes, but I
haven't seen them posted, or I can't seem to find them in my limited
email archive.

Karol, what's the status of them?
