Every TUN Read went through several multi-case selects. We know from past experience with wireguard-go that these are slow and cause scheduler churn. The selects served two purposes: they separated errors from data and gracefully handled shutdown. The first is fairly easy to replace by sending errors and data over a single channel. The second, less so. We considered a few approaches: Intricate webs of channels, global condition variables. They all get ugly fast. Instead, let's embrace the ugly and handle shutdown ungracefully. It's horrible, but the horror is simple and localized. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com> |
