Replace all UnsafeCell-based counters with safe alternatives:
- New ShardedCounter: per-thread TLS accumulation (thread_local crate)
with periodic publish to static AtomicU64. Zero atomic RMW on hot path.
- ACL RuleStatsTracker: remove unsafe Arc<RuleStats> raw pointer
mutation, use two ShardedCounter fields.
- ZCPacket: replace set_len on uninitialized BytesMut with
write_bytes + copy_nonoverlapping before set_len.
- StatsManager UnsafeCounter/MetricData: remove UnsafeCell and
unsafe impl Send/Sync, wrap ShardedCounter. last_updated uses
AtomicU64 epoch millis.
- Throughput: replace UnsafeCell with AtomicU64.
- secure_datagram: fix grace-window test timestamp.
Replace std::time::Instant with quanta::Instant on per-packet, per-RPC,
and per-session paths. TSC-based, ~5ns vs ~25ns per now() call.
Reuses the existing `extern crate self as hotpath` alias so
`use hotpath::instant::Instant;` resolves to the same quanta type with
or without the hotpath feature. Leaves tokio::time::Instant and
smoltcp::time::Instant untouched.
* refactor(web): use generated proto network types
* fix(core): preserve dumped config flags
* test(web): cover config flag save paths
* fix(ci): use system protoc before frontend codegen
* fix(ci): serialize frontend-lib builds
Use pbjson to support string deserialization for enum fields
This allows TOML configs like:
chainType = "Inbound"
instead of:
chainType = 1
- Maintain backward compatibility with integer values
- Default serialization format is now string
TomlConfigLoader::new_from_str() always calls NetworkIdentity::new()
with unwrap_or_default() on network_secret, converting None to ''.
This creates a non-zero SHA256 digest, causing credential nodes loaded
from TOML to be misidentified as regular nodes (with network_secret),
which breaks Noise handshake authentication.
Fix: check if secure_mode is enabled AND network_secret is absent/empty,
and call NetworkIdentity::new_credential() in that case.
The same detection already exists in:
- core.rs (CLI path, via --credential flag)
- launcher.rs (GUI/web path, via gen_config)
This makes TOML config loading consistent with the other two entry points.
Adds a Linux-only socket_mark u32 config flag (CLI: --socket-mark, env:
ET_SOCKET_MARK, TOML/proto: flags.socket_mark, 0 = disabled) that is
applied as SO_MARK to every outbound underlay socket EasyTier creates:
TCP, UDP, QUIC, WebSocket, WireGuard connectors and listeners, plus the
FakeTCP decoy socket. Lets the host policy-route or filter EasyTier
underlay traffic with 'ip rule fwmark ...' or iptables -m mark.
Plumbing mirrors the existing bind_device pattern:
- FlagsInConfig.socket_mark (proto) + default 0 in gen_default_flags
- bind() builder gets a socket_mark arg; setup_socket2_ext calls
apply_socket_mark which is a no-op for mark=0 and on non-Linux
- TunnelConnector trait gets set_socket_mark(u32) default-no-op method
- IP-based connectors override; create_listener_by_url and the connector
factory pass mark from global_ctx flags
- QUIC threads mark through QuicEndpointManager::{server,connect}
- WebSocket/FakeTCP/TCP default-bind bypass paths apply mark via
socket2::SockRef::from(&tokio_socket)
- ForeignNetworkEntry propagates parent socket_mark into its derived ctx
Includes a Linux smoke test plus a CAP_NET_ADMIN-gated test that does a
getsockopt(SO_MARK) round-trip to confirm the kernel applied the value.
SO_MARK requires CAP_NET_ADMIN; ignored silently on non-Linux. FakeTCP's
TUN-written segments are not covered (kernel doesn't tag raw TUN
writes); operators relying on fwmark for FakeTCP must apply an iptables
rule on the FakeTCP TUN device separately.

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
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

* 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.
