When a node has public IPv6 addresses allocated by EasyTier, those addresses
are installed on the host's network interfaces. The system would then pick
them up as candidate source/destination addresses for underlay connections
(direct peer, UDP hole punch, bind addresses), causing overlay traffic to
loop back into the overlay itself.
Add a central predicate is_ip_easytier_managed_ipv6() and apply it at every
point where IPv6 addresses are selected for underlay use:
- Filter managed IPv6 from DNS-resolved connector addresses, including a
UDP socket getsockname check to detect whether the OS would route through
the overlay to reach a destination
- Skip managed IPv6 in bind address selection and STUN candidate filtering
- Strip managed IPv6 from GetIpListResponse RPC so peers never learn them
- Pass pre-resolved addresses to tunnel connectors to avoid re-resolution

- add lazy_p2p so nodes only start background P2P for peers that actually have recent business traffic
- add need_p2p so specific peers can still request eager background P2P even when other nodes enable lazy mode
- cover the new behavior with focused connector/peer-manager tests plus three-node integration tests that verify relay-to-direct route transition
* feat: separate faketcp into a feature
* fix: no need to initialize out_len
* feat: separate zstd into a feature
* clippy: remove unnecessary cast, because for unix size_t always equals usize
support faketcp to avoid tcp-over-tcp problem.
linux/macos/windows are supported.
better to be used in internet env, the maximum
performance is majorly limited by windivert/raw socket.
1. dns resolver should be global unique so dns cache can work. avoid dns query influence hole punching.
2. when system dns failed, fallback to hickory dns.
This patch removes Tarpc & Tonic GRPC and implements a customized rpc framework, which can be used by peer rpc and cli interface.
web config server can also use this rpc framework.
moreover, rewrite the public server logic, use ospf route to implement public server based networking. this make public server mesh possible.
