* all: new p2p node representation (#17643)Felix Lange2018-09-252-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Package p2p/enode provides a generalized representation of p2p nodes which can contain arbitrary information in key/value pairs. It is also the new home for the node database. The "v4" identity scheme is also moved here from p2p/enr to remove the dependency on Ethereum crypto from that package. Record signature handling is changed significantly. The identity scheme registry is removed and acceptable schemes must be passed to any method that needs identity. This means records must now be validated explicitly after decoding. The enode API is designed to make signature handling easy and safe: most APIs around the codebase work with enode.Node, which is a wrapper around a valid record. Going from enr.Record to enode.Node requires a valid signature. * p2p/discover: port to p2p/enode This ports the discovery code to the new node representation in p2p/enode. The wire protocol is unchanged, this can be considered a refactoring change. The Kademlia table can now deal with nodes using an arbitrary identity scheme. This requires a few incompatible API changes: - Table.Lookup is not available anymore. It used to take a public key as argument because v4 protocol requires one. Its replacement is LookupRandom. - Table.Resolve takes *enode.Node instead of NodeID. This is also for v4 protocol compatibility because nodes cannot be looked up by ID alone. - Types Node and NodeID are gone. Further commits in the series will be fixes all over the the codebase to deal with those removals. * p2p: port to p2p/enode and discovery changes This adapts package p2p to the changes in p2p/discover. All uses of discover.Node and discover.NodeID are replaced by their equivalents from p2p/enode. New API is added to retrieve the enode.Node instance of a peer. The behavior of Server.Self with discovery disabled is improved. It now tries much harder to report a working IP address, falling back to 127.0.0.1 if no suitable address can be determined through other means. These changes were needed for tests of other packages later in the series. * p2p/simulations, p2p/testing: port to p2p/enode No surprises here, mostly replacements of discover.Node, discover.NodeID with their new equivalents. The 'interesting' API changes are: - testing.ProtocolSession tracks complete nodes, not just their IDs. - adapters.NodeConfig has a new method to create a complete node. These changes were needed to make swarm tests work. Note that the NodeID change makes the code incompatible with old simulation snapshots. * whisper/whisperv5, whisper/whisperv6: port to p2p/enode This port was easy because whisper uses []byte for node IDs and URL strings in the API. * eth: port to p2p/enode Again, easy to port because eth uses strings for node IDs and doesn't care about node information in any way. * les: port to p2p/enode Apart from replacing discover.NodeID with enode.ID, most changes are in the server pool code. It now deals with complete nodes instead of (Pubkey, IP, Port) triples. The database format is unchanged for now, but we should probably change it to use the node database later. * node: port to p2p/enode This change simply replaces discover.Node and discover.NodeID with their new equivalents. * swarm/network: port to p2p/enode Swarm has its own node address representation, BzzAddr, containing both an overlay address (the hash of a secp256k1 public key) and an underlay address (enode:// URL). There are no changes to the BzzAddr format in this commit, but certain operations such as creating a BzzAddr from a node ID are now impossible because node IDs aren't public keys anymore. Most swarm-related changes in the series remove uses of NewAddrFromNodeID, replacing it with NewAddr which takes a complete node as argument. ToOverlayAddr is removed because we can just use the node ID directly.

* p2p, p2p/discover, p2p/discv5: implement UDP port sharing (#15200)Felföldi Zsolt2018-01-221-4/+3
| | | | | | | | | | | | | | | This commit affects p2p/discv5 "topic discovery" by running it on the same UDP port where the old discovery works. This is realized by giving an "unhandled" packet channel to the old v4 discovery packet handler where all invalid packets are sent. These packets are then processed by v5. v5 packets are always invalid when interpreted by v4 and vice versa. This is ensured by adding one to the first byte of the packet hash in v5 packets. DiscoveryV5Bootnodes is also changed to point to new bootnodes that are implementing the changed packet format with modified hash. Existing and new v5 bootnodes are both running on different ports ATM.
* p2p/simulations: various stability fixes (#15198)Lewis Marshall2017-12-012-13/+23
| | | | | | | | | | | | | | | | | | | | | | | | p2p/simulations: introduce dialBan - Refactor simulations/network connection getters to support avoiding simultaneous dials between two peers If two peers dial simultaneously, the connection will be dropped to help avoid that, we essentially lock the connection object with a timestamp which serves as a ban on dialing for a period of time (dialBanTimeout). - The connection getter InitConn can be wrapped and passed to the nodes via adapters.NodeConfig#Reachable field and then used by the respective services when they initiate connections. This massively stablise the emerging connectivity when running with hundreds of nodes bootstrapping a network. p2p: add Inbound public method to p2p.Peer p2p/simulations: Add server id to logs to support debugging in-memory network simulations when multiple peers are logging. p2p: SetupConn now returns error. The dialer checks the error and only calls resolve if the actual TCP dial fails.

* cmd/utils, node: create account manager in package nodeFelix Lange2016-08-173-11/+89
| | | | | | | | | | | | | | | The account manager was previously created by packge cmd/utils as part of flag processing and then passed down into eth.Ethereum through its config struct. Since we are starting to create nodes which do not have eth.Ethereum as a registered service, the code was rearranged to register the account manager as its own service. Making it a service is ugly though and it doesn't really fix the root cause: creating nodes without eth.Ethereum requires duplicating lots of code. This commit splits utils.MakeSystemNode into three functions, making creation of other node/service configurations easier. It also moves the account manager into Node so it can be used by those configurations without requiring package eth.
