Bug 609000

Description of problem:

openconnect succeeds the first time I setup the vpn but triggers a selinux access error on later attempts

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

libselinux-2.0.90-5.fc12
selinux-policy-targeted-3.6.32-118
selinux-policy-3.6.32-118
libselinux-utils-2.0.90-5
openconnect-2.22-1
NetworkManager-openconnect-0.8.0-1.git20100411

How reproducible:

The error appears reproducible only after I setup and shutdown the vpn once. I need to reboot to be able to get it to work again later

Steps to Reproduce:
1. connect to vpn (success)
2. disconnect from vpn
3. connect to vpn
  
Actual results:

network manager reports a vpn connection failure, I get a selinux error popup (copied below). Sometimes, despite the vpn connection failure message, the network manager icon in the toolbar shows a successful connection icon (but the connection really does not work).

Expected results:

Hopefully, the vpn would work all the time.

Additional info:

Summary:

SELinux is preventing /usr/bin/openconnect "relabelfrom" access .

Detailed Description:

[openconnect has a permissive type (vpnc_t). This access was not denied.]

SELinux denied access requested by openconnect. It is not expected that this
access is required by openconnect 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:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.
