You can add these rules now using # grep avc /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Fixed in selinux-policy-3.6.12-57.fc11 I added the rules and now the VPN client works, but I'm getting a new SELinux alert:
SELinux is preventing openvpn (openvpn_t) "open" security_t.

Same problem. You can run the command above again. But as soon as selinux-policy-3.6.12-57.fc11 becomes available, these will be fixed. You can safely ignore these. Thanks you Daniel. Similar issue.

I place my config/cert files in /etc/openvpn and can't connect.
Summary:
SELinux is preventing openvpn (openvpn_t) "read" security_t.
Detailed Description:
SELinux denied access requested by openvpn. It is not expected that this access
is required by openvpn 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.

You need to upgrade policy, yum -y upgrade selinux-policy-targeted If this does not pull a new one down, execute yum -y upgrade selinux-policy-targeted --enablerepo=updatestesting Using selinux-policy-targeted 3.6.12-62.fc11 and it's fixed. |
I've configured the OpenVPN client from NM using the keys/certs at $HOME/openvpn. When I try to connect, SELinux blocked the operation with two menssages: 1) SELinux is preventing openvpn (openvpn_t) "read" to user.crt (user_home_t). 2) SELinux is preventing openvpn (openvpn_t) "read" security_t. 1) Gets fixed easily with (although IMHO this should be enabled by default when NetworkManager-openvpn is installed): setsebool -P openvpn_enable_homedirs=1 2) I can't get rid of this one. The suggested solution is: 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.
