Package: selinux-policy-default
Version: 2:2.20110726-12
Severity: normal


on a freshly upgraded wheey, on boot, ircbalance produce a avc :

May  5 14:22:32 venser kernel: [   11.593105] type=1400 audit(1367756552.598:9): avc:  denied  { getsched } for  pid=549 comm="irqbalance" scontext=system_u:system_r:irqbalance_t:s0 tcontext=system_u:system_r:irqbalance_t:s0 tclass=process

Indeed getsched is missing from the set of permission :

/home/misc# sesearch -s irqbalance_t -t irqbalance_t -A -c process  
Found 1 semantic av rules:
   allow irqbalance_t irqbalance_t : process { fork sigchld sigkill sigstop signull signal getcap setcap } ;
