* p2p/discover: implement node bondingFelix Lange2015-04-011-50/+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 portsFelix Lange2015-02-071-193/+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.
