Description Klaus Heinrich Kiwi 2007-04-02 19:00:56 UTC
Description of problem:
When querying jobs with sysadm_r role using lpq or lpstat, cups is not
overriding mls (sysadm_t has mlsfileread attribute)

Version-Release number of selected component (if applicable):
cups-1.2.4-11.8.el5

How reproducible:
every time

Steps to Reproduce:
1. Log-in as any SystemHigh-SystemHigh user
2. Print/enqueue a job
3. Log in as sysadm_r/SystemLow(-SystemHigh) user
4. query jobs using lpq -al $job# or lpstat -W all $InstanceName
  
Actual results:
even root/sysadm_r/sysadm_t can't see jobs above it's clearance

Expected results:
sysadm_r should be able to see jobs above it's clearance, because of mlsfileread
 policy attribute

Additional info:
Is this actually stricter than LSPP? I'm ok with it given that LSPP/RBAC also
are. Either way this needs to be fixed or documented.
