WireGuard In The Kernel – WireGuard sadly didn’t make it into the mainline Linux kernel in 2018 as they hoped to, but it’s looking like it will for sure make it in this year… WireGuard is the very promising open-source secure VPN tunnel that is already available for other operating systems / platforms and has the out-of-tree DKMS kernel module working quite well for upping network security. WireGuard is already offered by some VPN providers and I am quite excited to see how far its adoption will go this year.
