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.

Comment 1 Lukas Pramuk 2016-03-08 12:33:13 UTC 
More convenient report:

# sudo audit2allow -a


#============= streamer_t ==============
allow streamer_t locale_t:dir { read search open getattr };
allow streamer_t locale_t:file { read getattr open };
#!!!! The source type 'streamer_t' can write to a 'dir' of the following types:
# mnt_t, root_t, cluster_conf_t, cluster_var_lib_t, cluster_var_run_t

allow streamer_t pulp_var_run_t:dir { write remove_name search add_name };
#!!!! The source type 'streamer_t' can write to a 'file' of the following types:
# mnt_t, root_t, cluster_conf_t, cluster_var_lib_t, cluster_var_run_t

allow streamer_t pulp_var_run_t:file { write create unlink open getattr };

The Pulp upstream bug status is at NEW. Updating the external tracker on this bug.
Comment 3 pulp-infra@redhat.com 2016-03-09 16:06:20 UTC 
The Pulp upstream bug priority is at Normal. Updating the external tracker on this bug.
Comment 4 Brian Bouterse 2016-03-09 17:13:08 UTC 
As rbarlow suggested, I highly suspect this is a duplicate of https://pulp.plan.io/issues/1711. Have you tried with our most recent beta (0.8 I think)? Please try it since the upstream bug will very likely be closed on Friday at triage as a duplicate.
Comment 5 Lukas Pramuk 2016-03-10 11:19:35 UTC 
I agree that issue #1756 is a duplicate of #1711.
Comment 6 Lukas Pramuk 2016-03-10 12:21:13 UTC 
Tested upstream pulp-selinux-2.8.0-0.8.beta.el6.noarch.rpm without any selinux denials.
Comment 7 pulp-infra@redhat.com 2016-03-10 18:24:45 UTC 
The Pulp upstream bug status is at ON_QA. Updating the external tracker on this bug.
Comment 8 pulp-infra@redhat.com 2016-03-10 18:24:47 UTC 
The Pulp upstream bug priority is at Normal. Updating the external tracker on this bug.
Comment 9 Brad Buckingham 2016-03-22 14:51:42 UTC 
Moving to POST, since fix is available upstream.
Comment 11 pulp-infra@redhat.com 2016-03-23 18:30:25 UTC 
The Pulp upstream bug status is at CLOSED - CURRENTRELEASE. Updating the external tracker on this bug.
