[SOLVED] OpenVPN service causes Kodi to stop

[snarf]

Hi, hopefully someone has seen this before and I'm just missing something obvious...

Software
XBian version: 20150919-1 (updated 2015-10-3)
XBMC/Kodi version: 15.2-RC2 Git:2015-09-13-2d0c3cf
Overclock settings: Default (off?)

Hardware
Device type and model: Raspberry Pi Model B 512 MB
Power supply rating: 1.2A
SD card size and make/type: Sandisk 16GB class 6
Network: Ethernet
Connected devices (TV, USB, network storage, ...): None / headless

Log files
Link to logfile(s): kodi.log

Problem description:
Installing and running OpenVPN package causes Kodi to be non-functioning. Stopping the VPN service allows Kodi to be restarted but it fails again as soon as OpenVPN is started again.

I'm struggling to find anything in the logfile that highlights a conflict and the upstart log isn't helpful either.

How to reproduce:
Vanilla build of Xbian.
Add "tun" to /etc/modules (or modules.xbian)
apt-get install openvpn (tested with 2.3.4-5 from Jessie and 2.3.7-2 from Stretch)
Copy appropriate .conf, .crt and .pem files to /etc/openvpn
Either service openvpn start or openvpn path/to/profile.conf to start vpn.
Kodi stops. Will not restart until vpn is taken down.

Reboot - same thing - Kodi down until openvpn service stopped.

Edit: forgot to include that I mounted an NFS share from my Synology NAS to copy the files from. xxx.xxx.xxx.xxx:/volume1/downloads /mnt/downloads nfs rw,defaults,intr,vers=3 0 0 added to /etc/fstab

Same issue here. Eth-0 is down, wifi is ok.

I goth similar results with RC2. However I had some apt-get commands manually running in the past, so my results may or may not be authentic.

A segmentation fault is happening, as soon, as I start the service.

I could not get any traces from the system, neither via GUI, nor via the advanced settings XML file.
I planned to re-install a clean system, and re-try, but did not get to it yet.

Did anyone get it working with TUN + ETH + OpenVPN?

Same for me here.
I just freshly installed Xbian because I had a few issues with kodi under raspbian.
Right out of the box, I installed openvpn from repo, flashed my usual conf, and boom: kodi disappeared from the TV.

any help would be highly appreciated

Did system update today (20151011-1) and the problem persists.

Funny thing, I have the exact same issue with setting up an IPv6 tunnel using Aiccu to Sixxs using: https://www.sixxs.net/tools/aiccu/

Looks like this may be a Kodi issue being fixed in latest builds.

I just updated to kodi 15 rc3 and with am still experiencing the issue with aiccu. Is the OpenVPN issue fixed? Maybe I am looking in the wrong place.

I also updated and the issue persists for me.

I also updated and the issue persists for me.
With latest packages installed, I've ran a gdb session on the source, and got following result:

Terminal

Unfortunatelly I could not match the right source from git (even, if I got the 15.2RC3 src).
I suspect, the TUN interface is not digestable for the source, ifconfig brings this for tun0:

Terminal

root@xbian /usr/lib/debug # ifconfig tun0
tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

I can confirm that this issue has been resolved with my most recent update (xbian-package-xbmc_15.2-1446621231).
