Felföldi Zsolt	d96870428f	les: UDP pre-negotiation of available server capacity (#22183) ... This PR implements the first one of the "lespay" UDP queries which is already useful in itself: the capacity query. The server pool is making use of this query by doing a cheap UDP query to determine whether it is worth starting the more expensive TCP connection process.	4 years ago
Nishant Das	429e7141f2	p2p/discover: fix deadlock in discv5 message dispatch (#21858) ... This fixes a deadlock that could occur when a response packet arrived after a call had already received enough responses and was about to signal completion to the dispatch loop.

Felix Lange	524aaf5ec6	p2p/discover: implement v5.1 wire protocol (#21647) ... This change implements the Discovery v5.1 wire protocol and also adds an interactive test suite for this protocol.	4 years ago
Nishant Das	7a63faf734	p2p/discover: add helper methods to UDPv5 (#20918) ... This adds two new methods to UDPv5, AllNodes and LocalNode. AllNodes returns all the nodes stored in the local table; this is useful for the purposes of metrics collection and also debugging any potential issues with other discovery v5 implementations. LocalNode returns the local node object. The reason for exposing this is so that users can modify and set/delete new key-value entries in the local record.	4 years ago
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
