Felix Lange	c420dcb39c	p2p: enforce connection retry limit on server side (#19684) ... The dialer limits itself to one attempt every 30s. Apply the same limit in Server and reject peers which try to connect too eagerly. The check against the limit happens right after accepting the connection. Further changes in this commit ensure we pass the Server logger down to Peer instances, discovery and dialState. Unit test logging now works in all Server tests.	6 years ago
Felix Lange	6f607de5d5	p2p, p2p/discover: add signed ENR generation (#17753) ... This PR adds enode.LocalNode and integrates it into the p2p subsystem. This new object is the keeper of the local node record. For now, a new version of the record is produced every time the client restarts. We'll make it smarter to avoid that in the future. There are a couple of other changes in this commit: discovery now waits for all of its goroutines at shutdown and the p2p server now closes the node database after discovery has shut down. This fixes a leveldb crash in tests. p2p server startup is faster because it doesn't need to wait for the external IP query anymore.	6 years ago
Felix Lange	9123eceb0f	p2p, p2p/discover: misc connectivity improvements (#16069) ... * p2p: add DialRatio for configuration of inbound vs. dialed connections * p2p: add connection flags to PeerInfo * p2p/netutil: add SameNet, DistinctNetSet * p2p/discover: improve revalidation and seeding This changes node revalidation to be periodic instead of on-demand. This should prevent issues where dead nodes get stuck in closer buckets because no other node will ever come along to replace them. Every 5 seconds (on average), the last node in a random bucket is checked and moved to the front of the bucket if it is still responding. If revalidation fails, the last node is replaced by an entry of the 'replacement list' containing recently-seen nodes. Most close buckets are removed because it's very unlikely we'll ever encounter a node that would fall into any of those buckets. Table seeding is also improved: we now require a few minutes of table membership before considering a node as a potential seed node. This should make it less likely to store short-lived nodes as potential seeds. * p2p/discover: fix nits in UDP transport We would skip sending neighbors replies if there were fewer than maxNeighbors results and CheckRelayIP returned an error for the last one. While here, also resolve a TODO about pong reply tokens.	7 years ago
Felix Lange	30d706c35e	cmd/geth: add --config file flag (#13875) ... * p2p/discover, p2p/discv5: add marshaling methods to Node * p2p/netutil: make Netlist decodable from TOML * common/math: encode nil HexOrDecimal256 as 0x0 * cmd/geth: add --config file flag * cmd/geth: add missing license header * eth: prettify Config again, fix tests * eth: use gasprice.Config instead of duplicating its fields * eth/gasprice: hide nil default from dumpconfig output * cmd/geth: hide genesis block in dumpconfig output * node: make tests compile * console: fix tests * cmd/geth: make TOML keys look exactly like Go struct fields * p2p: use discovery by default This makes the zero Config slightly more useful. It also fixes package node tests because Node detects reuse of the datadir through the NodeDatabase. * cmd/geth: make ethstats URL settable through config file * cmd/faucet: fix configuration * cmd/geth: dedup attach tests * eth: add comment for DefaultConfig * eth: pass downloader.SyncMode in Config This removes the FastSync, LightSync flags in favour of a more general SyncMode flag. * cmd/utils: remove jitvm flags * cmd/utils: make mutually exclusive flag error prettier It now reads: Fatal: flags --dev, --testnet can't be used at the same time * p2p: fix typo * node: add DefaultConfig, use it for geth * mobile: add missing NoDiscovery option * cmd/utils: drop MakeNode This exposed a couple of places that needed to be updated to use node.DefaultConfig. * node: fix typo * eth: make fast sync the default mode * cmd/utils: remove IPCApiFlag (unused) * node: remove default IPC path Set it in the frontends instead. * cmd/geth: add --syncmode * cmd/utils: make --ipcdisable and --ipcpath mutually exclusive * cmd/utils: don't enable WS, HTTP when setting addr * cmd/utils: fix --identity	8 years ago
Felix Lange	1d80155d5e	p2p/netutil: new package for network utilities ... The new package contains three things for now: - IP network list parsing and matching - The WSAEMSGSIZE workaround, which is duplicated in p2p/discover and p2p/discv5.	8 years ago
