| Summary | 0008815: ReceiverAddress.d_mq isn't destroyed if it hasn't yet been registered in udp communicator | ||||
| Description | Both d_mq and kx_mq are created when the ReceiverAddress is, and kx_mq is immediately registered with the transport api, while d_mq is only registered after the key exchange has completed. Once registered, the transport api takes over the lifetime of the mq, and it is indirectly destroyed via GNUNET_TRANSPORT_communicator_mq_del. If receiver_destroy is called before then, though, d_mq is leaked. | ||||
| Steps To Reproduce | 1. Build gnunet with --enable-sanitizer 2. Start the node with gnunet-arm -s 3. Stop the node after a bit with gnunet-arm -e 4. Observe reported memory leak wherever you've configured communicator-udp to log to | ||||
