Right now, filtering and packet injection in wgengine depend on a patch to wireguard-go that probably isn't suitable for upstreaming. This need not be the case: wireguard-go/tun.Device is an interface. For example, faketun.go implements it to mock a TUN device for testing. This patch implements the same interface to provide filtering and packet injection at the tunnel device level, at which point the wireguard-go patch should no longer be necessary. This patch has the following performance impact on i7-7500U @ 2.70GHz, tested in the following namespace configuration: ┌────────────────┐ ┌─────────────────────────────────┐ ┌────────────────┐ │ $ns1 │ │ $ns0 │ │ $ns2 │ │ client0 │ │ tailcontrol, logcatcher │ │ client1 │ │ ┌─────┐ │ │ ┌──────┐ ┌──────┐ │ │ ┌─────┐ │ │ │vethc│───────┼────┼──│vethrc│ │vethrs│──────┼─────┼──│veths│ │ │ ├─────┴─────┐ │ │ ├──────┴────┐ ├──────┴────┐ │ │ ├─────┴─────┐ │ │ │10.0.0.2/24│ │ │ │10.0.0.1/24│ │10.0.1.1/24│ │ │ │10.0.1.2/24│ │ │ └───────────┘ │ │ └───────────┘ └───────────┘ │ │ └───────────┘ │ └────────────────┘ └─────────────────────────────────┘ └────────────────┘ Before: --------------------------------------------------- | TCP send | UDP send | |------------------------|------------------------| | 557.0 (±8.5) Mbits/sec | 3.03 (±0.02) Gbits/sec | --------------------------------------------------- After: --------------------------------------------------- | TCP send | UDP send | |------------------------|------------------------| | 544.8 (±1.6) Mbits/sec | 3.13 (±0.02) Gbits/sec | --------------------------------------------------- The impact on receive performance is similar.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains all the open source Tailscale code. It currently includes the Linux client.
The Linux client is currently cmd/relaynode, but will
soon be replaced by cmd/tailscaled.
Using
We serve packages for a variety of distros at https://pkgs.tailscale.com .
Building
go install tailscale.com/cmd/tailscale{,d}
We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.14) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
