Minima IPv6 quick and dirty POC #622

Open towelbyte opened 1 day ago

towelbyte commented 1 day ago

This is a quick and dirty hack, but working prototype, for Minima partial IPv6 support as a proof of concept; for demonstration purposes.

This allows for peers IP:PORT to be defined for IPv6 addresses as well, by simple notation: e.g.: fda9:e0aa:589f::2:9001. For proper implementation we may want to only allow the unambiguous square brackets notation, e.g.: [fda9:e0aa:589f::2]:9001 ?

For proper implementation we may want to filter-out "local" addresses: link local (fe80::/10) and unique local (fc00::/7), and loopback (::1/128). Analogous as the code currently does with IPv4 (and then an -allip option override).

Testing: Running on testnet in docker containers w/ unique local IPv6 addresses.

Can send messages over Maxima; Maxima contact addresses w/ IPv6:

"contact":"MxG18HGG6FJ038614Y8CW46US6G20810K0070CD00Z83282G60G13P2JWVKB65Y6C9H4SCM03RY9DRFSBYDAVTRZ3286DRC6426MHAEZZ3GB8G23VCR5EWN82R22843R34056M06Z6BQEY6SJKYGEWZZ3J9T9WHFHSVNFBS222YA0QDAVYGGGNR4HSBNZ87JNHFAJ08ZQQVMP64M1GHHDSEHCEUZ110303NJBW1TUGD5D3CTK0Z5UD3QBSDVFZUUK10608006QWVV1A@fda9:e0aa:589f:0:0:0:0:4:9001"

This does mean that such a node may not be able to communicate over Maxima with a node that may only be connectable via IPv4 (as this node's maxima contact address has only an IPv6 relay address).

The current assumption is there is 1 relay IPv4 address in the Maxima contact address. If adding IPv6 support, maybe Maxima addresses could be extended to be able to have 1 or more IPv4 and/or IPv6 addresses of relay nodes? Maybe simply separated by a comma? e.g.:

"contact":"MxG18HGG6FJ038614Y8CW46US6G20810K0070CD00Z83282G60G13P2JWVKB65Y6C9H4SCM03RY9DRFSBYDAVTRZ3286DRC6426MHAEZZ3GB8G23VCR5EWN82R22843R34056M06Z6BQEY6SJKYGEWZZ3J9T9WHFHSVNFBS222YA0QDAVYGGGNR4HSBNZ87JNHFAJ08ZQQVMP64M1GHHDSEHCEUZ110303NJBW1TUGD5D3CTK0Z5UD3QBSDVFZUUK10608006QWVV1A@fda9:e0aa:589f:0:0:0:0:4:9001,172.20.0.4"

There may be additional backwards compatibility considerations to think of.

node 2: Add initial peer as an IPv6 address:port 

peers action:addpeers peerslist:fda9:e0aa:589f::2:9001
{
  "command":"peers",
  "params":{
    "action":"addpeers",
    "peerslist":"fda9:e0aa:589f::2:9001"
  },
  "status":true,
  "pending":false,
  "response":{
    "valid":"[fda9:e0aa:589f::2:9001]",
    "invalid":"[]",
    "message":"Valid peers added to checking queue.."
  }
}

node 1: after node 2 has added it as its initial peer:

Netstat shows connections via IPv4 and IPv6. I don't know why multiple connections to the same IP:PORT occur, though.
