timcooijmans	7b5107b73f	p2p/discover: avoid dropping unverified nodes when table is almost empty (#21396) ... This change improves discovery behavior in small networks. Very small networks would often fail to bootstrap because all member nodes were dropping table content due to findnode failure. The check is now changed to avoid dropping nodes on findnode failure when their bucket is almost empty. It also relaxes the liveness check requirement for FINDNODE/v4 response nodes, returning unverified nodes as results when there aren't any verified nodes yet. The "findnode failed" log now reports whether the node was dropped instead of the number of results. The value of the "results" was always zero by definition.

Felix Lange	b7394d7942	p2p/discover: add initial discovery v5 implementation (#20750) ... This adds an implementation of the current discovery v5 spec. There is full integration with cmd/devp2p and enode.Iterator in this version. In theory we could enable the new protocol as a replacement of discovery v4 at any time. In practice, there will likely be a few more changes to the spec and implementation before this can happen.	5 years ago
