Race condition in TcpStreamFactory could result in CreateStream returning a NetworkStream with a closed Socket

    • Type: Icon: Bug Bug
    • Resolution: Fixed
    • Priority: Icon: Major - P3 Major - P3
    • 2.10.1
    • Affects Version/s: 2.10.0
    • Component/s: Connectivity
    • None

      If a timeout or cancellation request happens AFTER `socket.Connect` returns but BEFORE the `connected` variable is set to true the socket could be Closed before the Connect helper method returns:

      The window for the race condition is VERY small and therefore low probability.
