Since RIOT is an operating system the native binary will never terminate [0]. The termination condition for fuzzing GNRC is that the packet was handled by the network stack and therefore freed. If it is never freed we will deadlock meaning a memory leak was found, afl should be able to detect this through timeouts. This is currently only supported for gnrc_pktbuf_malloc since this is the pktbuf implementation I used for fuzzing. Implementing this in pktbuf.h is not possible. [0]: Except NATIVE_AUTO_EXIT is defined, however, even with that define set RIOT will only terminate when all threads terminated. Unfortunately, gnrc_udp and other network threads will never terminate.
