Me five hours ago: "Get everything out of the kernel!"

Couldn't they use eBPF for that? At least for the decryption phase.

I see no upstreaming roadmap for the kernel driver. Upstreaming into the main Linux kernel does trigger a lot of peer review.

Funny how chrome made firefox much better and now wireguard made openvpn much better.

Would be interesting to compare it to classic userspace-only OpenVPN and WireGuard.

Sounds like there's an overlap with what ProtonVPN has been doing with OpenVPN to improve performance: https://protonvpn.com/blog/vpn-accelerator/
