This would protect against a non-privileged QP trying to change multicast or event subscription, for example. Though it could help with DoS, by avoiding the processing associated with requests. Jason's original question was why would you want to leave qp1 open, and I think the answer to that depends on what restrictions could be enforced for qpX: X > 1. Restricting both seem desirable, IMO. _______________________________________________ Selinux mailing list [email protected] To unsubscribe, send email to [email protected].
