[$] WireGuard bounces off FreeBSD—for now

The WireGuard VPN tunnel is afast and easy-to-use solution for those who need or want a secure tunnelfor their traffic. The project has been around since 2016, but it has had asomewhat circuitous route into Linux; it was merged for the 5.6kernel, which was released in March 2020. Getting into Linux requiredWireGuard developer Jason A. Donenfeld to acquiesce to having WireGuard use some of theexisting kernel crypto primitives, rather than merging his Zinc crypto library. Some of the sametensions that were seen in that process seem to be cropping up again in the morerecent efforts to add WireGuard support to several BSD kernels.
