I just sent a v1 of this patch: https://lore.kernel.org/lkml/20220217162848.303601-1-Jason@z... We'll see if that elicits any real objections. Hopefully not, and this will be part of 5.18!

The general idea is to clean things up piecemeal and gradually, until we've got a coherent design that's easy to reason about and enables us to then start working on proofs and formal verification, discussions with the academic cr

Worth noting that BIOS updates frequently ship with ucode updates that are applied at boot before UEFI executes the operating system. So if GP is diligent about keeping the BIOS up to date, it's conceivable that Linux's ucode upda

Wintun -- https://www.wintun.net -- actually uses this technique via shared memory ring buffers. And Winsock RIO has something similar for packets. We were using both of these already prior to WireGuardNT. They're fast but

Routing is actually a layer before packets make it to the WireGuardNT miniport driver. Usually the routing table controls this, but WFP callout drivers can also steer traffic to specific adapters based on things like process image path or s

I would love to work on this, but indeed it won't happen without Apple's blessing. It would be terrific to work with them on this, though!

Security is the top priority. But being useful is also important; if nobody can use it, nobody benefits from that security. Acceptable performance is very important for being useful, especially when tunneling layer 3 packets, where latency
