Author	SHA1	Message	Date
Ricardo Catalinas Jiménez	436fc8d76a	all: Rename crypto.Sha3{,Hash}() to crypto.Keccak256{,Hash}() ... As we aren't really using the standarized SHA-3	9 years ago
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.	9 years ago
Felix Lange	d1f507b7f1	p2p/discover: support incomplete node URLs, add Resolve	9 years ago
Gustav Simonsson	c8ad64f33c	crypto, crypto/ecies, crypto/secp256k1: libsecp256k1 scalar mult ... thanks to Felix Lange (fjl) for help with design & impl	9 years ago
Felix Lange	dd54fef898	p2p/discover: don't attempt to replace nodes that are being replaced ... PR #1621 changed Table locking so the mutex is not held while a contested node is being pinged. If multiple nodes ping the local node during this time window, multiple ping packets will be sent to the contested node. The changes in this commit prevent multiple packets by tracking whether the node is being replaced.	9 years ago
Felix Lange	bfbcfbe4a9	all: fix license headers one more time ... I forgot to update one instance of "go-ethereum" in commit 3f047be5a.	9 years ago
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".	9 years ago
Felix Lange	ea54283b30	all: update license information	10 years ago
Felix Lange	2adcc31bb4	p2p/discover: new distance metric based on sha3(id) ... The previous metric was pubkey1^pubkey2, as specified in the Kademlia paper. We missed that EC public keys are not uniformly distributed. Using the hash of the public keys addresses that. It also makes it a bit harder to generate node IDs that are close to a particular node.	10 years ago
Felix Lange	72ab6d3255	p2p/discover: track sha3(ID) in Node	10 years ago
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
Péter Szilágyi	6def110c37	cmd/bootnode, eth, p2p, p2p/discover: clean up the seeder and mesh into eth.	10 years ago
Péter Szilágyi	af923c965f	p2p/discovery: use the seed table for finding nodes, auto drop stale ones	10 years ago
Péter Szilágyi	5f735d6fce	cmd, eth, p2p, p2p/discover: init and clean up the seed cache	10 years ago
Felix Lange	936c8e19ff	p2p/discover: store nodes in leveldb	10 years ago
Felix Lange	b8aeb04f6f	p2p/discover: remove unused field Node.activeStamp	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	82f0bd9009	p2p/discover: code review fixes	10 years ago
Felix Lange	8564eb9f7e	p2p/discover: add node URL functions, distinguish TCP/UDP ports ... The discovery RPC protocol does not yet distinguish TCP and UDP ports. But it can't hurt to do so in our internal model.	10 years ago
