internal/windows: deadlock in function interfaceHandle() #134

Closed stenya closed 1 year ago

stenya commented 1 year ago

Deadlock (infinite loop) happens when interfaceHandle() is called after the device was closed.

Issue explanation in code:

func issueTest() {
 devName := "your-device-name"

 client, _ := wgctrl.New()
 defer client.Close()

 client.Device(devName) // ok

 // TODO: disable (disconnect) WireGuard connection

 client.Device(devName) // BUG: deadlock in interfaceHandle() method !!!
}
