Stephen, please indulge my curiousities and explain what this mediates? As I understand the process affinities, these hooks would mediate how tightly a process is bound to a specific group of processors to help prevent cache thrashing; I don't see a point to mediating cpu affinity in an access control module. (Well, aside from covert timing channels, but I thought we more or less came to an agreement that covert channels were out of scope for a 2.6 LSM?) Why? :) Thanks Stephen -- "There's an old saying in Tennessee, i know it's in Texas, probably in Tennessee, that says, 'Fool me once... shame on ... shame on .. you; but fool--you can't get fooled again.'" -- Commander in Chief of the US Military
