Hello,
I'm unable to load the wireguard kernel module on Debian Sid or Debian Buster. (4.19.0-5-amd64 kernel)
(Debian buster is scheduled to be promoted to stable in a couple of weeks)
root@buster:~# modprobe wireguard
modprobe: ERROR: could not insert 'wireguard': Invalid argument
root@buster:~# modinfo wireguard

alias: rtnl-link-wireguard

srcversion: 69000E9D4B2B253E97C189A
depends: udp_tunnel,ip6_udp_tunnel
retpoline: Y
name: wireguard
vermagic: 4.19.0-5-amd64 SMP mod_unload modversions
The same version seems to work fine on Debian Stretch (4.9.0-9) or Fedora Core 30 (5.1.11-300)
The kernel ring throws a number of symbol version errors:
[...]
[ 97.450944] wireguard: loading out-of-tree module taints kernel.
[ 97.453335] wireguard: module verification failed: signature and/or required key missing - tainting kernel

[...]
I have tried both the apt package from debian unstable, as well as compile from source.
Any idea what could be going wrong? Is this a Debian kernel bug?
Thanks in advance,
Nils

Hi Nils,
I've been unable to reproduce this on a vanilla VM built using `vagrant init debian/buster64; vagrant up`:
root@buster:/home/vagrant# modprobe wireguard
root@buster:/home/vagrant# modinfo wireguard

root@buster:/home/vagrant# uname -a
Linux buster 4.19.0-5-amd64 #1 SMP Debian 4.19.37-3 (2019-05-15) x86_64 GNU/Linux
The above output was from the WireGuard package from testing, I got similar results compiling WireGuard 0.0.20190601 from source too.
Can you check which version of the linux-image-4.19.0-5-amd64 package you have installed? I'm running 4.19.37-3 for reference.
Cheers,
Steven

I have this kernel on Debian Stretch (from backports) and wireguard works
just fine with it.
