Péter Szilágyi 04fcae207d p2p: if no nodes are connected, attempt dialing bootnodes (#13874) 2017-04-10 18:33:41 +02:00
Felix Lange a47341cf96 p2p, p2p/discover, p2p/discv5: add IP network restriction feature
The p2p packages can now be configured to restrict all communication to
a certain subset of IP networks. This feature is meant to be used for
private networks.

Felix Lange 542b839ec7 node, p2p: move network config out of Server
This silences a go vet message about copying p2p.Server in package node.

Felix Lange 6c41e675ec p2p: resolve incomplete dial targets
This change makes it possible to add peers without providing their IP
address. The endpoint of the target node is resolved using the discovery
protocol.

Felix Lange 04c6369a09 p2p, p2p/discover: track bootstrap state in p2p/discover
This change simplifies the dial scheduling logic because it
no longer needs to track whether the discovery table has been
bootstrapped.

Felix Lange bfbcfbe4a9 all: fix license headers one more time
I forgot to update one instance of "go-ethereum" in commit 3f047be5a.

Felix Lange 3f047be5aa all: update license headers to distiguish GPL/LGPL
All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".

Felix Lange 1440f9a37a p2p: new dialer, peer management without locks
The most visible change is event-based dialing, which should be an
improvement over the timer-based system that we have at the moment.
The dialer gets a chance to compute new tasks whenever peers change or
dials complete. This is better than checking peers on a timer because
dials happen faster. The dialer can now make more precise decisions
about whom to dial based on the peer set and we can test those
decisions without actually opening any sockets.

Peer management is easier to test because the tests can inject
connections at checkpoints (after enc handshake, after protocol
handshake).

Most of the handshake stuff is now part of the RLPx code. It could be
exported or move to its own package because it is no longer entangled
with Server logic.
