Description Milos Malik 2011-06-08 09:27:03 UTC 
Description of problem:
iprinit, iprdump and iprupdate services work well with targeted policy, but
they struggle with MLS policy.

iprinit - IBM Power RAID adapter/device initialization utility
iprupdate - IBM Power RAID adapter/device microcode update utility
iprdump - IBM Power RAID adapter dump utility

Version-Release number of selected component (if applicable):
selinux-policy-2.4.6-311.el5
selinux-policy-devel-2.4.6-311.el5
selinux-policy-minimum-2.4.6-311.el5
selinux-policy-mls-2.4.6-311.el5
selinux-policy-strict-2.4.6-311.el5
selinux-policy-targeted-2.4.6-311.el5
iprutils-2.3.4-1.el5

How reproducible:
always

Steps to Reproduce:
(have a ppc64 machine with MLS policy installed, runlevel 3, logged in as root via console)
# setenforce 1
# run_init service iprinit start
Authenticating root.
Password: 
Starting ipr initialization daemon
/bin/bash: line 1:  3361 Segmentation fault      /sbin/iprinit --daemon
