About Renice demanding monotonical increases
Hi
I was wondering why exactly renice doesn't allow normal users to undo decreases in priority to their own processes.
I know the man's talk about this but I didn't understand exactly why this constitutes a problem.
What exactly does it mean "administrative fiats"?
I suppose this security measure is to allow some sort of sophisticated attack.
From renice's man:
"Users other than the super-user may only alter the priority of processes
they own, and can only monotonically increase their ``nice value'' within
the range 0 to PRIO_MAX (20). (This prevents overriding administrative
fiats.)"
Thanks
