Hey list, Various networking people have been poking and prodding about supporting IPv6 Link Local addresses and about supporting special multicast addresses. *I MAY VERY WELL NEVER CHOOSE TO IMPLEMENT THIS* but in case I do, I wanted to start spec'ing out what this might look like in order to think about it better. There are a lot of odd concerns to take into account, so I doubt that the below will wind up as a final solution.
For these two options below, I introduce them with corresponding configuration nobs. Since I don't really like adding nobs, it's entirely likely that on the small chance I do wind up implementing this, it would be without the nobs and just always on. == Multicast == # wg set wg0 multicast on When multicast mode is turned on, packets sent to the special address ranges 224.0.0.0/24 or fe02::/16 are sent to every peer on that interface. == IPv6 Link Local Addresses == # wg set wg0 llv6 on This command fails and returns -ENOTUNIQ if two existing peers have the same value of hash(pubkey). When this command succeeds:, the wg0 interface receives an automatically assigned IP address of fe80::hash(interfacepubkey)/64. Every peer has fe80::hash(peerpubkey)/128 implicitly added to their allowed-ips. When adding a new peer, if hash(pubkey) is the same value of an existing peer, the command fails and returns -ENOTUNIQ. I'm open to thoughts and suggestions about the above ideas.
