Oh, I see. This is fall-out from https://bugzilla.redhat.com/show_bug.cgi?id=1139646 , I think, which gave /dev/net/tun the svirt_image_t type. I've confirmed this locally as well. Workaround is the following: # grep openvpn /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp This is also preventing /usr/sbin/vpnc from doing similarly:
***** Plugin catchall (100. confidence) suggests **************************
If you believe that vpnc should be allowed read access on the tun chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep vpnc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
