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 Milos Malik 2017-04-06 19:46:50 UTC 
+++ This bug was initially created as a clone of Bug #1439875 +++

Description of problem:

I've noticed a strange interaction with custom ports and booleans. After setting a boolean, the list of ports for a particular type (which has been customized) shows duplicate entries.

Example:

  $ semanage port -a -t http_port_t -p tcp 12345
  $ semanage port -l | grep http_port_t
  http_port_t                    tcp      12345, 80, 81, ...
  $ setsebool -P zebra_write_config false
  $ semanage port -l | grep http_port_t
  http_port_t                    tcp      12345, 12345, 80, 81, ...
  $ setsebool -P zebra_write_config false
  $ semanage port -l | grep http_port_t
  http_port_t                    tcp      12345, 12345, 12345, 80, 81, ...

As can be seen, each time a boolean is set persistently (it doesn't matter which boolean or which state), the custom port 12345 is duplicated. Running "semodule -B" clears the duplicates.

However, if only the local customizations are listed, the port is always listed only once:

  $ semanage port -l -C
  SELinux Port Type              Proto    Port Number
  http_port_t                    tcp      12345

Version-Release number of selected component (if applicable):
libselinux-ruby-2.5-11.el7.x86_64
libselinux-devel-2.5-11.el7.x86_64
libselinux-2.5-11.el7.x86_64
libselinux-python-2.5-11.el7.x86_64
libselinux-utils-2.5-11.el7.x86_64

How reproducible:
Always
