Daniel, do you know what you were doing when this happened (and also AVC msgs which you reported)? /* Allow raising priority and setting priority on other (different UID) processes */ /* Allow use of FIFO and round-robin (realtime) scheduling on own processes and setting the scheduling algorithm used by another process. */ /* Allow setting cpu affinity on other processes */ Must be a plugin trying to do one of these ^^ It is the first one. The call was: sched_setscheduler(10976, 0, 7fff443ec370) 10976 was this process pid. 0 == SCHED_NORMAL We don't know what the sched_param structure at that address had for the sched_priority. This process must have attempted to up its priority. This does not seem like something we want to allow. Dontaudited in the current release. |
