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.

Fixed In Version: policycoreutils-2.0.83-21.el6
Doc Type: Bug Fix
Doc Text:
The semanage utility previously listed only changes made to the currently used SELinux policy. For example, when the targeted policy was loaded and changes were made to the Multi-Level Security (MLS) policy, the "semanage -S mls -o" command did not list all the changes, even when the changes were applied correctly. This bug has been fixed, and semanage now lists all changes as expected.

Description Michal Trunecka 2014-07-24 08:30:29 UTC 
Description of problem:
semanage -S mls -o -    seems to show always the changes for the currently loaded policy. Changes made to e.g. mls policy seems to be applied correctly, but are not shown in this listing.

For example, when targeted policy is used:

##### Both listings for targeted and mls are empty (showing just fcontext part):
# semanage -o -
....
fcontext -D
# semanage -S mls -o -
....
fcontext -D

##### I add fcontext rule to mls storage
# semanage fcontext -S mls -a -N -t httpd_sys_content_t /test1

##### ..and it is not shown in niether:
# semanage -o -
....
fcontext -D
# semanage -S mls -o -
....
fcontext -D

##### But it is in the correct config file:
# cat /etc/selinux/mls/modules/active/file_contexts.local 
  # This file is auto-generated by libsemanage
  # Do not edit directly.

  /test1    system_u:object_r:httpd_sys_content_t:s0
##### And not in the targeted:
# cat /etc/selinux/targeted/modules/active/file_contexts.local 

  # This file is auto-generated by libsemanage
  # Do not edit directly.

Are you getting AVCs?  Does it work in permissive mode?

I has not been fixed yet.

The proposed patch wouldn't work when semanage is called without -S. This one should fix it:
