RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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 Robert Scheck 2016-03-11 13:38:56 UTC 
Description of problem:
Enabling mod_proxy65 of Prosody according to

  http://prosody.im/doc/modules/mod_proxy65

on the default port 5000 leads to the following errors:

Mar 11 14:08:38 socket  warn    server.lua, [::]:5000: permission denied
Mar 11 14:08:38 portmanager     error   Failed to open server port 5000 on ::, Prosody does not have sufficient privileges to use this port
Mar 11 14:08:38 socket  warn    server.lua, [*]:5000: permission denied
Mar 11 14:08:38 portmanager     error   Failed to open server port 5000 on *, Prosody does not have sufficient privileges to use this port

This issue does not occur with SELinux permissive, however there are also
no AVC denials logged in enforced mode. Given this port is configurable, a
prosody_port_t should be likely introduced to allow binding Prosody to any
port labelled with prosody_port_t (because even standard 5222/5223/5269
ports can be changed, see e.g. http://xmpp.org/rfcs/rfc3920.html).

And given TCP port 5000 is a default port by Prosody, this should be allowed
IMHO by default by the SELinux policy as well.

Version-Release number of selected component (if applicable):
prosody-0.9.10-1.el7.x86_64
selinux-policy-3.13.1-60.el7_2.3.noarch

How reproducible:
Everytime, see above and below.

Actual results:
SELinux does not allow Prosody to listen on port 5000 for mod_proxy65.

Expected results:
SELinux allows Prosody to listen on port 5000 for mod_proxy65.
Comment 1 Robert Scheck 2016-03-11 13:42:49 UTC 
Ah, now that I opened this bug, I noticed that jabber_interserver_port_t
and jabber_client_port_t exist - but that still leaves the port 5000 thing.
Comment 3 Miroslav Grepl 2016-03-14 08:31:51 UTC 
Just to be sure, could you attach AVCs?

Thank you.
Comment 4 Robert Scheck 2016-03-24 23:32:57 UTC 
Getting these AVCs required "semodule -DB":
