[Uber low priority] Linux 4.17.0 on aarch64

2018-06-07 Thread Riccardo Berto
Just want to report that I can't add a wg interface of type wireguard 
with linux 4.17.0 on aarch64 (Raspberry Pi 3).


Error message: `RTNETLINK answers: Operation not supported`.

I'm using ArchLinuxARM. Downgrading to 4.16.x makes the issue dissapear. 
This is not high-priority so please Jason, if you're reading this 
message, move this issue further down in your debugging queue as I 
believe almost nobody is using 4.17.0 on aarch64 right now. Maybe 
they'll fix the error by themselves in the coming 4.17.x releases.

Did you actually compile the wireguard kernel module? Or rely on mysterious
"them" to do so?

I compiled it through a dkms hook of pacman, the ArchLinuxARM pkg 
manager. It runs everytime there is a new kernel installation, being it 
an upgrade or a downgrade.


Those mysterious and shady "them" are the mainline patch submitters LOL

I had the same problem on a different Archlinux ARM kernel that I fixed
by adding '-fno-pic' to the ccflags-y line in Kbuild before compiling
wireguard. Try that out?
