1032670 - FxOS UDP sockets closed on WiFi status change

Status: RESOLVED INVALID

(Core :: Networking, defect)

On Firefox OS devices, if I open a UDP socket:

let UDPSocket = CC("@mozilla.org/network/udp-socket;1",
                   "nsIUDPSocket",
                   "init");
let socket = new UDPSocket(-1, false);
socket.asyncListen({
  onStopListening: function(socket, status) {
    console.log(status);
  }
});

and then I toggle the WiFi connectivity state (change from WiFi enabled to disabled), then the socket is closed with the status NS_ERROR_ABORT.  To regain communication after WiFi is enabled again, currently you have to recreate a new socket.

On desktop platforms (or at least on OS X), the socket remains working and can be reused after you toggle the OS's WiFi connectivity.

Also, FxOS TCP sockets *do* remain listening between WiFi state changes, so this is somehow specific to UDP.

Sorry, looks like this is as intended.  I was comparing to the debugger's TCP socket, which has set KeepWhenOffline.
