When the VPN is disconnected, stopSelf() triggers onDestroy(), which calls close(). onRevoke() also calls close(). Both these calls do serviceDisconnect on the service, sending the service to the onDisconnect channel twice. This fix: -only calls CloseTuns for the current VPN service (unconditional call was killing the newly established VPN) -calls setWantRunning(false) when a VPN revokes Tailscale to -check permissions and prepare VPN service before starting the VPN, since VPN permission is revoked in onRevoke Fixes tailscale/tailscale#17190 Signed-off-by: kari-ts <kari@tailscale.com>
