Description of problem:


Version-Release number of selected component (if applicable):
selinux-policy-targeted-2.4.6-35.fc6

How reproducible:
Open LVM management application. sealert comes up with a denial alert.

Steps to Reproduce:
1. Make sure setroubleshootd and sealert are running.
2. Open LVM management application.
3.
  
Actual results:
sealert comes up with a denial alert. Nothing noticeable goes wrong in the LVM
manager (tested in enforcing mode and permissive mode to compare).

Expected results:
No alert.

Additional info:

From sealert:

"Detailed Description
SELinux denied access requested by /usr/sbin/lvm. It is not expected that this
access is required by /usr/sbin/lvm and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access
Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for /usr/share/system-config-lvm/lvm_model.py,
restorecon -v /usr/share/system-config-lvm/lvm_model.py If this does not work,
there is currently no automatic way to allow this access. Instead, you can
generate a local policy module to allow this access - see FAQ Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report against this package.
