Description Murray McAllister 2008-08-12 02:35:58 EDT

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

* Fedora release 9 (Sulphur)
* Linux 2.6.25.11-97.fc9.i686 i686

* shadow-utils-4.1.1-2.fc9.i386

* policycoreutils-2.0.52-5.fc9.i386
* selinux-policy-targeted-3.3.1-82.fc9.noarch
* libselinux-python-2.0.67-4.fc9.i386
* selinux-policy-3.3.1-82.fc9.noarch
* selinux-policy-devel-3.3.1-82.fc9.noarch
* libselinux-2.0.67-4.fc9.i386

* xguest-1.0.6-7.fc9.noarch

How reproducible:

Always.

Steps to Reproduce:

1. yum install xguest
2. useradd -Z guest_u selinuxtest
3. semanage login -l
selinuxtest               guest_u                   s0

4. usermod -Z user_u selinuxtest
usermod: no changes

5. semanage login -l
selinuxtest               guest_u                   s0 
  
Actual results:

The Linux "selinuxtest" user stays mapped to "guest_u".

Expected results:

The Linux "selinuxtest" user mapped to "user_u".

Additional info:

There are no AVC denials. The same results occur when not using xguest, for example, using "root" and "user_u" instead.

SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   enforcing
Mode from config file:          enforcing
Policy version:                 22
Policy from config file:        targeted

Works as expected on:

* Red Hat Enterprise Linux Client release 5.2 (Tikanga)
* Linux 2.6.18-92.1.1.el5 i686

shadow-utils-4.0.17-13.el5

* policycoreutils-1.33.12-14.el5

* libselinux-python-1.33.4-5.el5
* selinux-policy-2.4.6-137.el5
* libselinux-1.33.4-5.el5

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