Description Murray McAllister 2008-09-03 02:26:08 UTC 
Description of problem:

Running "semanage translation -a -T Secret s0:c2" causes denials and setrans.conf mode changes.

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

* Red Hat Enterprise Linux Server release 5.2 (Tikanga)

* policycoreutils-1.33.12-14.el5

* setroubleshoot-2.0.5-3.el5
* setroubleshoot-server-2.0.5-3.el5
* setroubleshoot-plugins-2.0.4-2.el5

* selinux-policy-targeted-2.4.6-137.1.el5_2
* selinux-policy-2.4.6-137.1.el5_2
* libselinux-devel-1.33.4-5.el5
* libselinux-python-1.33.4-5.el5
* libselinux-devel-1.33.4-5.el5
* libselinux-1.33.4-5.el5
* libselinux-1.33.4-5.el5

SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   permissive
Mode from config file:          permissive
Policy version:                 21
Policy from config file:        targeted


How reproducible:
Always

Steps to Reproduce:
1. ls -l /etc/selinux/targeted/setrans.conf 
-rw-r--r-- 1 root root 598 Jul  2 01:13 /etc/selinux/targeted/setrans.conf

2. semanage translation -a -T Secret s0:c2

3. ls -l /etc/selinux/targeted/setrans.conf 
-rw------- 1 root root 611 Sep  3 12:10 /etc/selinux/targeted/setrans.conf
  
Actual results:
No errors; translation added; lots of AVC denials; setrans.conf mode changed from 644 to 600.

Expected results:
No AVC denials and setrans.conf mode stays as 644.

Additional info:

See attached denials from /var/log/messages and /var/log/audit/audit.log

Woops wrong bug.  Some of this is fixed in 5.3 policy but needs to be completed in 5.4.

Following 2 commands are part of /CoreOS/policycoreutils/Regression/bz460970-semanage-translation-a-causes-denials test.

# semanage translation -a -T secret s0:c2
env: /etc/init.d/mcstrans: Permission denied
# echo $?
0
# semanage translation -d -T secret s0:c2
env: /etc/init.d/mcstrans: Permission denied
# echo $?
0

Each of them generated 1 AVC:
