Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Pavel Moravec 2015-04-08 08:41:26 UTC 
Description of problem:
foreman-debug checking for SELinux denials wrongly reports also USER_AVC records like below example. Those are logs of policy load and not real denials. foreman-debug then wrongly reports "DENIALS: 12" to stdout.


Version-Release number of selected component (if applicable):
foreman-debug-1.7.2.15-1.el7sat.noarch


How reproducible:
100%


Steps to Reproduce:
1. e.g. on freshly installed RHEL7.1 and Sat6.1 (most probably reproducible anywhere), run foreman-debug
2. Check it's output and selinux_denials.log it generates


Actual results:
foreman-debug output having:


 HOSTNAME: pmoravec-sat61.gsslab.brq.redhat.com
       OS: redhat
  RELEASE: Red Hat Enterprise Linux Server release 7.1 (Maipo)
  FOREMAN: 1.7.2
     RUBY: ruby 2.0.0p598 (2014-11-13) [x86_64-linux]
   PUPPET: 3.6.2
  DENIALS: 12


selinux_denials.log having 12 records like:
time->Wed Apr  8 09:31:02 2015
type=USER_AVC msg=audit(1428478262.651:1213): pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='avc:  received policyload notice (seqno=11)  exe="/usr/lib/systemd/systemd" sauid=0 hostname=? addr=? terminal=?'


Expected results:
foreman-debug output to have "DENIALS: 0"
selinux_denials.log without the USER_AVC logs


Additional info:
/me not sure what all audit logs could be of USER_AVC type, or if there could be also real denials. But definitely the above logs are not SELinux denials and should not be reported as such by foreman-debug.
