Description Alex Villacís Lasso 2015-01-05 00:01:12 UTC
Description of problem:
In my Fedora 21 setup, gogoc wants to open /proc/net/tun but is prevented from doing so since gogog.service has PrivateDevices=yes . Therefore, the ipv6 tunnel fails to start at all.

Version-Release number of selected component (if applicable):
gogoc-1.2-40.fc21.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Attempt to start gogoc with systemctl start gogoc.service
2.
3.

Actual results:
[root@karlalex ~]# systemctl status gogoc.service
● gogoc.service - Freenet6.net tunnel client to IPv6
   Loaded: loaded (/usr/lib/systemd/system/gogoc.service; disabled)
   Active: active (running) since dom 2015-01-04 18:22:36 ECT; 32s ago
     Docs: man:gogoc(8)
           man:gogoc.conf(5)
 Main PID: 5642 (gogoc)
   CGroup: /system.slice/gogoc.service

ene 04 18:22:43 karlalex.palosanto.com gogoc[5642]: Failed to initialize TUN device.


Expected results:
The service should either succeed in opening /dev/net/tun or use an alternate means of setting up the tunnel interface.

Additional info:
Removing the PrivateDevices=yes flag from gogoc.service allows the service to start correctly.
