Go Implementation of WireGuard
This is an implementation of WireGuard in Go.
WARNING: This is a work in progress and not ready for prime time, with no official "releases" yet. It is extremely rough around the edges and leaves much to be desired. There are bugs and we are not yet in a position to make claims about its security. Beware.
Usage
Most Linux kernel WireGuard users are used to adding an interface with ip link add wg0 type wireguard. With wireguard-go, instead simply run:
$ wireguard-go wg0
This will create an interface and fork into the background. To remove the interface, use the usual ip link del wg0, or if your system does not support removing interfaces directly, you may instead remove the control socket via rm -f /var/run/wireguard/wg0.sock, which will result in wireguard-go shutting down.
To run wireguard-go without forking to the background, pass -f or --foreground:
$ wireguard-go -f wg0
When an interface is running, you may use wg(8) to configure it, as well as the usual ip(8) and ifconfig(8) commands.
To run with more logging you may set the environment variable LOG_LEVEL=debug.
Platforms
Linux
This will run on Linux; however YOU SHOULD NOT RUN THIS ON LINUX. Instead use the kernel module; see the installation page for instructions.
macOS
This runs on macOS using the utun driver. It does not yet support sticky sockets, and won't support fwmarks because of Darwin limitations. Since the utun driver cannot have arbitrary interface names, you must either use utun[0-9]+ for an explicit interface name or utun to have the kernel select one for you. If you choose utun as the interface name, and the environment variable WG_TUN_NAME_FILE is defined, then the actual name of the interface chosen by the kernel is written to the file specified by that variable.
Windows
It is currently a work in progress to strip out the beginnings of an experiment done with the OpenVPN tuntap driver and instead port to the new UWP APIs for tunnels. In other words, this does not yet work on Windows.
FreeBSD
This will run on FreeBSD. It does not yet support sticky sockets. Fwmark is mapped to SO_USER_COOKIE.
OpenBSD
This will run on OpenBSD. It does not yet support sticky sockets. Fwmark is mapped to SO_RTABLE. Since the tun driver cannot have arbitrary interface names, you must either use tun[0-9]+ for an explicit interface name or tun to have the program select one for you. If you choose tun as the interface name, and the environment variable WG_TUN_NAME_FILE is defined, then the actual name of the interface chosen by the kernel is written to the file specified by that variable.
Building
This requires an installation of go and of dep. If dep is not installed, it will be downloaded and built as part of the build process.
$ git clone https://git.zx2c4.com/wireguard-go
$ cd wireguard-go
$ make
