Wireguard problem on Xavier

Hi there,

I’m currently experiencing some issues with the Wireguard protocol on my Jetson device. Even though I’ve installed it successfully, it doesn’t seem to be working as expected. Whenever I try to run it, an error message pops up.

$ sudo wg-quick up wg0
[#] ip link add wg0 type wireguard
Error: Unknown device type.
Unable to access interface: Protocol not supported
[#] ip link delete dev wg0
Cannot find device "wg0"

When I try to load Wirguard module by hand:

$ sudo modprobe wireguard && lsmod | grep -i wireguard
modprobe: FATAL: Module wireguard not found in directory /lib/modules/5.10.104-tegra

and When I try to build Wireguard module from the source:

$ make -C wireguard-linux-compat/src -j$(nproc)
make: Entering directory '/home/imperiumdrive/javad/wireguard-linux-compat/src'

I believe the issue is tied to the Kernel header since Tegra utilizes a personalized kernel. Is there a solution available to resolve this problem?

Hi!

I had the same issue with Wireguard, but on the Orin NX plattform. I guess it’s the same procedure for the AGX, like for the Orin NX. The issue is, that Wireguard moved from 5.6 Linux Kernel to a official kernel module. This kernel module isn’t activated by the JetPack on default, but you can active it on the Jetson device. I’ve wrote a Wiki-Entry for that: Build new Kernel on EdgeKit · PCB-Arts/edgekit Wiki · GitHub

After that it’s possible to add the wg0 interface:

root@edgekit-desktop:/boot# ip a | grep wg
12: wg0-client-OSl: <POINTOPOINT,NOARP> mtu 1420 qdisc noop state DOWN group default qlen 1000

Hope this helps!

Hi,
We don’t have much experience on this. Thank saber.kaygusuz for sharing suggestion.

Thanks a lot,
On 18.04 I installed it by following Wireguard instructions on building from the source (Compilation from Source Code - WireGuard)
I will test your method on 20.04

Make sense, that it worked on 18.04, since it is the 4.9 kernel (without the build-in Wireguard-module).
