Replace NicCtx's direct VirtualNic field with NicBackend while keeping the constructor on the dedicated backend path.
Move existing device creation, ifcfg lookup, IP assignment, and public IPv6 updater calls through backend helpers so shared mode can be wired in a later commit without changing the dedicated flow.
Introduce SharedVirtualNicMember as the per-instance handle for a shared virtual NIC and add a registry helper to create members.
Add NicBackend so NicCtx can later choose between dedicated VirtualNic and shared member-backed tunnel creation without changing the existing dedicated path.
Move TUN-specific configuration into VirtualNicConfig so VirtualNic and SharedVirtualNic no longer depend on ArcGlobalCtx.
Keep global context side effects in NicCtx, including the Windows generated device-name writeback.
This may helps games to find rooms in virtual network.
- add opt-in Windows UDP broadcast relay config flag and CLI/env plumbing
- capture local UDP broadcasts with Windows raw sockets, normalize packets, and inject them via PeerManager
* 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.

Also rename stale interfaces from previous runs before creating new ones.
Works around rust-tun reusing existing tun0 instead of configured name.
Tested on FreeBSD 14.1
* refactor: update global context STUN server initialization
Modified global context initialization to use a single StunInfoCollector
instance with properly configured IPv4 and IPv6 servers instead of
creating separate instances.
feat: add IPv6 STUN server configuration support
Added interface methods and config struct fields to support both IPv4
and IPv6 STUN server configuration. Modified getter and setter methods
to handle Option<Vec<String>> type for both server types.
feat: enhance StunInfoCollector with IPv6 support
Updated StunInfoCollector to support both IPv4 and IPv6 STUN servers.
Added new constructor that accepts both server types and methods to set
them independently.
feat: add CLI argument for IPv6 STUN servers
Added command line argument support for configuring IPv6 STUN servers.
Updated configuration setup to handle both IPv4 and IPv6 STUN server
settings.
docs: add localization for STUN server configuration
Added English and Chinese localization strings for the new STUN server
configuration options, including both IPv4 and IPv6 variants.
sometimes route table may not be updated in time, so some dead nodes are still showing in the peer list.
when generating ipv4-peer table, we should avoid these dead devices overrides the entry of healthy nodes.
This patch implements:
1. A dns server that handles .et.net. zone in local and forward all other queries to system dns server.
2. A dns server instance which is a singleton in one machine, using one specific tcp port to be exclusive with each other. this instance is responsible for config system dns and run the dns server to handle dns queries.
3. A dns client instance that all easytier instance will run one, this instance will try to connect to dns server instance, and update the dns record in the dns server instance.
this pr only implements the system config for windows. linux & mac will do later.
* optimize memory issues
1. introduce jemalloc support, which can dump current memory usage
2. reduce the GlobalEvent broadcaster memory usage.
3. reduce tcp & udp tunnel memory usage
TODO: if peer conn tunnel hangs, the unbounded channel of peer rpc
may consume lots of memory, which should be improved.
* select a port from 15888+ when port is 0
icmp/udp proxy do not rely on kernel net stack, but currently not handle ip fragmentation correctly.
this patch add ip resembler to merge fragmented ip packet for udp/icmp proxy
* use correct i18n hook
* fix peer rpc panic
make sure server use correct transact id
* fix dhcp
recreate tun device after ip changed
* use upx correctly
* compile arm & armv7
* prepare to release v1.1.0
