[fabbione/kronosnet] 0d3ccb: [send/recv] Fix handling of HOSTINFO packets

by GitHub

Branch: refs/heads/master Home: https://github.com/fabbione/kronosnet Commit: 0d3ccb336b5b6445d6df8ba7b3afb628773a99a7 https://github.com/fabbione/kronosnet/commit/0d3ccb336b5b6445d6df8ba7b3afb6… Author: Fabio M. Di Nitto <fdinitto(a)redhat.com> Date: 2015-11-30 (Mon, 30 Nov 2015) Changed paths: M TODO M libknet/threads_send_recv.c Log Message: ----------- [send/recv] Fix handling of HOSTINFO packets HOSTINFO packets are nothing more than special cased DATA packets. The contents of HOSTINFO is stored inside DATA of DATA packets and up to the point where we need to use the HOSTINFO data, we need to treat the packets as DATA for defragmentation and deduplication. This also fixes a problem when using round-robin and active switching policy where the HOSTINFO exchange would loop forever in a storm because duplicate pckts were being handled at once.
