There's been a short series of patches (plus a short doc from James) to deal with code that's already doing uid/euid capable() checks w/out a corresponding LSM hook. IOW, it's already been recognized as security sensitive and has DAC check w/out corresponding MAC check. It's a small issue with relatively minor security impacts, but is completing mediation.
