v0.0.69: Initial WireGuard Modules

I've lost way too much sleep on this damn thing so tl'dr this is what I have:

1. Functional WireGuard kernel module.
2. Functional wg binary to control aforementioned tunnel interfaces.
3. UDP tunnel kmods for IPv4 and IPv6 if you want to compile a module that has dependencies on kernel UDP tunneling (e.g. WireGuard)

---

Prerequisites

• An MR1100. Can’t guarantee it’ll work on an MR2100 or an MR5000 if you’re so lucky to have one of those.
• Telnet. Or SSH. But wait you might say, I can already “Telnet” via port 5510! Well, my dear child, I’m exhausted af and so I really don’t want to delve into detail but what you think is “Telnet” is really nothing more than an illusion made by this lil tidbit: nc -l 192.168.1.1:5510 >/dev/smd7 </dev/smd7. Try again.
• A WireGuard “peer” to connect to. For practical purposes, this usually means a commercial VPN provider that supports WireGuard.

“Installation”

1. Throw dem mods into /usr/lib/modules/3.18.31/kernel/net/* ipv4 ipv6 and wireguard folders. Or not. I’m not your dad. Chuck em into /tmp or /dev/null for all I care.
2. depmod the UDP tunnel kernel mods.
3. depmod the wireguard mod.
4. Put wg wherever tf you want. If you don’t hate yourself, somewhere in your $PATH.

How to Use

1. Click here. Read everything.
2. depmod wireguard
3. Remember step 1 of this section? Good. Use all that info in your noggin to set it up. Or write a script to do it.
