描述

https://twitter.com/dstaley/status/1539773980692733952 has tips about SELinux.

As somebody who knows ~nothing about SELinux, I'm not sure what it's saying. (That's some sort of exception policy you put somewhere?)

EDIT 2023-01-23: see https://github.com/tailscale/tailscale/issues/4908#issuecomment-1400254802 below for an SELinux policy. This isn't yet built in to Tailscale.

研究方向
Review the SELinux policy shared in comment #1400254802 and the linked Twitter thread for context. Investigate how Tailscale's SSH feature currently interacts with system services and where SELinux policies should be applied. Then integrate the policy into the Tailscale build/packaging system, likely in the `cmd/tailscale/` or `cmd/tailscaled/` directories. Consider adding a script to install the policy or reference it in documentation.
