Felix Lange	fc747ef4a6	p2p/discover: new endpoint format ... This commit changes the discovery protocol to use the new "v4" endpoint format, which allows for separate UDP and TCP ports and makes it possible to discover the UDP address after NAT.	10 years ago

Felix Lange	936c8e19ff	p2p/discover: store nodes in leveldb	10 years ago
Felix Lange	635b66acdc	p2p: return zero node from Self if the server is not running ... This helps with fixing the tests for cmd/geth to run without networking.	10 years ago
Felix Lange	9c7281c17e	p2p: make DiscReason bigger than byte ... We decode into [1]DiscReason in a few places. That doesn't work anymore because package rlp no longer accepts RLP lists for byte arrays.	10 years ago
Felix Lange	eedbb1ee9a	p2p/discover: use rlp.DecodeBytes	10 years ago
Felix Lange	56a48101dc	cmd/rlpdump, cmd/utils, eth, p2p, whisper: use rlp input limit	10 years ago
Felix Lange	5528abc795	p2p: fix the dial timer ... The dial timer was not reset properly when the peer count reached MaxPeers.	10 years ago
obscuren	474aa924ca	p2p: added limiter function to limit package broadcasting	10 years ago
Felix Lange	0217652d1b	p2p/discover: improve timer handling for reply timeouts	10 years ago
Felix Lange	b8aeb04f6f	p2p/discover: remove unused field Node.activeStamp	10 years ago
Felix Lange	b9929d289d	p2p: fix unsynchronized map access during Server shutdown ... removePeer can be called even after listenLoop and dialLoop have returned.	10 years ago
Felix Lange	995fab2ebc	p2p: fix yet another disconnect hang ... Peer.readLoop will only terminate if the connection is closed. Fix the hang by closing the connection before waiting for readLoop to terminate. This also removes the british disconnect procedure where we're waiting for the remote end to close the connection. I have confirmed with @subtly that cpp-ethereum doesn't adhere to it either.	10 years ago
Felix Lange	79a6782c1c	p2p: fix goroutine leak when handshake read fails ... This regression was introduced in b3c058a9e4.	10 years ago
Felix Lange	c5332537f5	p2p: limit number of lingering inbound pre-handshake connections ... This is supposed to apply some back pressure so Server is not accepting more connections than it can actually handle. The current limit is 50. This doesn't really need to be configurable, but we'll see how it behaves in our test nodes and adjust accordingly.	10 years ago
Felix Lange	56977c225e	p2p: use RLock instead of Lock for pre-dial checks	10 years ago
Felix Lange	b3c058a9e4	p2p: improve disconnect signaling at handshake time ... As of this commit, p2p will disconnect nodes directly after the encryption handshake if too many peer connections are active. Errors in the protocol handshake packet are now handled more politely by sending a disconnect packet before closing the connection.	10 years ago
Felix Lange	99a1db2d40	p2p: don't mess with the socket deadline in Peer.readLoop ... netWrapper already sets a read deadline in ReadMsg.	10 years ago
Felix Lange	145330fdf2	p2p: properly decrement peer wait group counter for setup errors	10 years ago
Felix Lange	f1d710af00	p2p: fix Peer shutdown deadlocks ... There were multiple synchronization issues in the disconnect handling, all caused by the odd special-casing of Peer.readLoop errors. Remove the special handling of read errors and make readLoop part of the Peer WaitGroup. Thanks to @Gustav-Simonsson for pointing at arrows in a diagram and playing rubber-duck.	10 years ago
Felix Lange	22d1f0faf1	p2p: improve peer selection logic ... This commit introduces a new (temporary) peer selection strategy based on random lookups. While we're here, also implement the TODOs in dialLoop.	10 years ago
Felix Lange	7be05b4b9d	p2p/discover: don't log packet content	10 years ago
Felix Lange	9cd8c96157	p2p/discover: make packet processing less concurrent	10 years ago
obscuren	688d118c7e	Updated logging	10 years ago
Felix Lange	a77c431e37	p2p/discover: fix off by one error causing buckets to contain duplicates	10 years ago
Felix Lange	de7af720d6	p2p/discover: implement node bonding ... This a fix for an attack vector where the discovery protocol could be used to amplify traffic in a DDOS attack. A malicious actor would send a findnode request with the IP address and UDP port of the target as the source address. The recipient of the findnode packet would then send a neighbors packet (which is 16x the size of findnode) to the victim. Our solution is to require a 'bond' with the sender of findnode. If no bond exists, the findnode packet is not processed. A bond between nodes α and β is created when α replies to a ping from β. This (initial) version of the bonding implementation might still be vulnerable against replay attacks during the expiration time window. We will add stricter source address validation later.	10 years ago
Felix Lange	92928309b2	p2p/discover: add version number to ping packet ... The primary motivation for doing this right now is that old PoC 8 nodes and newer PoC 9 nodes keep discovering each other, causing handshake failures.	10 years ago
