If sender() fails again, deliver_err_response() is called with\n   the same recv_msg that was already queued for delivery\n\nThis causes list_add corruption (\"list_add double add\") because the\nrecv_msg is added to the user_msgs list twice. Subsequently, the\ncorrupted list leads to use-after-free when the memory is freed and\nreused, and eventually a NULL pointer dereference when accessing\nrecv_msg-\u003edone.\n\nThe buggy sequence:\n\n  sender() fails\n    -\u003e deliver_err_response(recv_msg)  // recv_msg queued for delivery\n    -\u003e goto restart                    // curr_msg not cleared!\n  sender() fails again (same message!)\n    -\u003e deliver_err_response(recv_msg)  // tries to queue same recv_msg\n    -\u003e LIST CORRUPTION\n\nFix this by freeing the message and setting it to NULL on a send error.\nAlso, always free the newmsg on a send error, otherwise it will leak."
