Description scheibel1 2012-08-15 13:48:50 UTC

Created attachment 1435 [details]
patch

on the following lines:

                  Ptr<Channel> chBridged = ndBridged->GetChannel ();
                  if (channel == 0)
                    {
                      continue;
                    }

in nix-vector-routing.cc GetAdjacentNetDevices the 'if' statement should be checking 'chBridged' rather than 'channel'.  Else there is the potential for this function to be recursively called with a null 'channel' param.  Patch included.
