* feat: support allocating public IPv6 addresses from a provider
Add a provider/leaser architecture for public IPv6 address allocation
between nodes in the same network:
- A node with `--ipv6-public-addr-provider` advertises a delegable
public IPv6 prefix (auto-detected from kernel routes or manually
configured via `--ipv6-public-addr-prefix`).
- Other nodes with `--ipv6-public-addr-auto` request a /128 lease from
the selected provider via a new RPC service (PublicIpv6AddrRpc).
- Leases have a 30s TTL, renewed every 10s by the client routine.
- The provider allocates addresses deterministically from its prefix
using instance-UUID-based hashing to prefer stable assignments.
- Routes to peer leases are installed on the TUN device, and each
client's own /128 is assigned as its IPv6 address.
Also includes netlink IPv6 route table inspection, integration tests,
and event-driven route/address reconciliation.

Fixes a CLI listener parsing regression where url crate special-casing for ws/wss could misinterpret inputs like ws:11011, and adds coverage to prevent future regressions.
Changes:
Refactors listener parsing to avoid url::Url parsing for proto:port forms and to support additional shorthand inputs (port-only / IP-only / SocketAddr).
Centralizes “expand to all IpScheme variants” logic in a helper (gen_listeners) while preserving the “port=0 is dynamic” behavior.
Adds unit tests covering valid/invalid listener inputs and expansion behavior.
- 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
Implement end-to-end encryption for core-web connections using the
Noise protocol framework with the following changes:
Client-side (easytier/src/web_client/):
- Add security.rs module with Noise handshake implementation
- Add upgrade_client_tunnel() for client-side handshake
- Add Noise frame encryption/decryption via TunnelFilter
- Integrate GetFeature RPC for capability negotiation
- Support secure_mode option to enforce encrypted connections
- Handle graceful fallback for backward compatibility
Server-side (easytier-web/):
- Accept Noise handshake in client_manager
- Expose encryption support via GetFeature RPC
The implementation uses Noise_NN_25519_ChaChaPoly_SHA256 pattern for
encryption without authentication. Provides backward compatibility
with automatic fallback to plaintext connections.
- add credential manager and RPC/CLI for generate/list/revoke
- support credential-based Noise authentication and revocation handling
- propagate trusted credential metadata through OSPF route sync
- classify direct peers by auth level in session maintenance
- normalize sender credential flag for legacy non-secure compatibility
- add unit/integration tests for credential join, relay and revocation
Use noise protocol on handshake. Check peer's public key if needed. Also support rekey and replay attack prevention.
E2EE and temporary password will be implemented based on this.
This PR fundamentally restructures the EasyTier GUI, introducing support for service mode and remote mode, transforming it from a simple desktop application into a powerful network management terminal. This change allows users to persistently run the EasyTier core as a background service or remotely manage multiple EasyTier instances, greatly improving deployment flexibility and manageability.
