I'm excited by this, but I'd really love a userspace C or C++ implementation. I know that context switching syscalls take time, but I've enjoyed the trend of the last 10 years towards more userspace services, not less. (I'm particularly thinking of filesystems in userspace and block devices in userspace)

Still, cool. cool, cool cool. I wonder how long until it's in debian.

I use BoringTun, it is written in Rust and runs entirely in user space.

Cool, thanks, I'll have to check that out!! I've sorta been itching for an excuse to learn rust. Go left me underwhelmed, but that's probably due to me having misplaced expectations. (it's not a better C or C++, it's a better Perl/Python/Shell)

There is also https://github.com/cloudflare/boringtun

Edit: Someone running wg in userspace and can share some experiences with either implementation?

The userspace wireguard-go implementation is slower than the kernel one. Some (I don't know how much) of that is the userspace <-> kernel barrier, but they're also totally different implementations (Go vs C).

I know you mean in stable, but it's been in unstable for 3+ years now!

I think he/she means "when will Debian ship with kernel 5.6 or greater".

Bingo. :)
