Description

If a node sends corrupted gossip, it could set the generation numbers for other nodes to arbitrarily large values. This is dangerous since one bad node (e.g. with bad memory) could in theory bring down the cluster. Nodes should refuse to accept generation numbers that are too far in the future.
