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 Ivan Necas 2014-11-14 08:53:07 UTC
Description of problem:
when setting up satellite to use proxy for communication, it
fails to use the proxy due to selinux issues


    type=AVC msg=audit(1412854812.878:760): avc:  denied  { name_connect } for  pid=12176 comm="ruby" dest=3128 scontext=system_u:system_r:passenger_t:

It does so for 3128 as well as 8080 port

Version-Release number of selected component (if applicable):

satellite-6.0.5
RHEL 7.0

How reproducible:
Always

Steps to Reproduce:
1. set up local squid (yum install -y squid; service squid start)
2. katello-installer --katello-proxy-url=http://localhost --katello-proxy-port=3128
3. katello-service restart
4. import manifest
5. try to enable some Red Hat repository

Actual results:
Fails on permission denied, AVC messages in audit.log

Expected results:
Everything works, the connection to the proxy is allowed.

Comment 2 Lukas Zapletal 2014-11-14 09:26:10 UTC
The workaround is to allow connects to the 8080 port.

Solution: Introduce new boolean for this.

Comment 4 Lukas Zapletal 2015-02-04 14:32:34 UTC
Correcting status, sorry about that :-)

Comment 10 Elyézer Rezende 2015-04-06 14:40:49 UTC
Verified on: Satellite-6.1.0-RHEL-7-20150331.1

Steps to verify:

1. Installed Satellite pointing to an external squid proxy on port 3128.
2. Imported a manifest
3. Enabled "Red Hat Enterprise Virtualization Agents for RHEL 6 Server RPMs x86_64 6Server" Red Hat repository and synced it.
4. Watched audit.log for AVC and no AVC was emitted during the process:

# tail -f /var/log/audit/audit.log | grep AVC
^C
#

Comment 11 Bryan Kearney 2015-08-11 13:31:02 UTC
This bug is slated to be released with Satellite 6.1.
