* | p2p/discover: bump maxBondingPingPongs to 16 | Felix Lange | 2015-05-14 | 1 | -1/+1 |
| | | | | | This should increase the speed a bit because all findnode results (up to 16) can be verified at the same time. | ||||
* | p2p/discover: new distance metric based on sha3(id) | Felix Lange | 2015-05-06 | 1 | -24/+30 |
| | | | | | | | 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. | ||||
* | p2p/discover: track sha3(ID) in Node | Felix Lange | 2015-04-30 | 1 | -5/+6 |

* | p2p/discover: new endpoint format | Felix Lange | 2015-04-30 | 1 | -7/+2 |
| | | | | | | 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. | ||||

* | p2p/discover: implement node bonding | Felix Lange | 2015-04-01 | 1 | -50/+133 |
| | | | | | | | | | | | | | | | | 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. | ||||

* | p2p/discover: add node URL functions, distinguish TCP/UDP ports | Felix Lange | 2015-02-07 | 1 | -193/+4 |
| | | | | | The discovery RPC protocol does not yet distinguish TCP and UDP ports. But it can't hurt to do so in our internal model. | ||||
