Description Jean-Luc Duprat 2007-05-04 20:09:43 UTC
Description of problem:
using Fedora 7 Test 4.  I am using OpenVPN and my client.conf script has the
following command in it:
up /etc/openvpn/clientup.sh

SELinux disallows running the script, generating the info atteched below. 
Should this be allowed through a boolean in the SELinux management tool?

---------

Summary
    SELinux is preventing sh (openvpn_t) "execute" to clientup.sh
    (openvpn_etc_t).

Detailed Description
    SELinux denied access requested by sh. It is not expected that this access
    is required by sh 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 clientup.sh, restorecon -v
    clientup.sh 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 http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385
    Or you can disable SELinux protection altogether. Disabling SELinux
    protection is not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

Same problem on CENTOS5/RHEL5 with openvpn from epel.

Comment 2 Bug Zapper 2008-04-04 00:30:41 UTC
Based on the date this bug was created, it appears to have been reported
against rawhide during the development of a Fedora release that is no
longer maintained. In order to refocus our efforts as a project we are
flagging all of the open bugs for releases which are no longer
maintained. If this bug remains in NEEDINFO thirty (30) days from now,
we will automatically close it.

If you can reproduce this bug in a maintained Fedora version (7, 8, or
rawhide), please change this bug to the respective version and change
the status to ASSIGNED. (If you're unable to change the bug's version
or status, add a comment to the bug and someone will change it for you.)

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

The process we're following is outlined here:
http://fedoraproject.org/wiki/BugZappers/F9CleanUp

We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.

Comment 3 Bug Zapper 2008-05-07 01:39:40 UTC
This bug has been in NEEDINFO for more than 30 days since feedback was
first requested. As a result we are closing it.

If you can reproduce this bug in the future against a maintained Fedora
version please feel free to reopen it against that version.
