Fix web/frontend compat bugs in managed config & runtime status
- Preserve [[peer]].peer_public_key when TOML configs round-trip
through the web/managed NetworkConfig path
- Keep old peer_urls clients working while adding structured peer
metadata for new clients
- Make frontend protobuf JSON normalization preserve omitted-field
semantics instead of turning missing data into misleading defaults
- Harden runtime status rendering against omitted or string-encoded
backend fields
- Expose peer-route feature flags in the web status UI
Fixes SOCKS5/port-forward handling for peer data packets
whose source endpoint was rewritten by the KCP or QUIC proxy path.
Keep SOCKS5 entry accounting consistent by centralizing insert/remove
operations, decrementing only for actual removals, avoiding underflow,
and resetting counts when entries are retained or cleared after IPv4 changes.
This PR fixes IPv6 UDP hole punching for peers with multiple public IPv6
addresses by adding two RPC signals:
- connector_addrs: connector-side candidate public IPv6 socket addresses
that the remote peer should punch back to.
- preferred_src_ipv6: remote listener IPv6 address that the remote peer
should use as the UDP source when sending hole-punch packets back.
Together, these let the connector try all usable local IPv6 candidates
while keeping the remote punch-back
packet sourced from the same IPv6 address that the connector is dialing.
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
Handle TUN receive errors by marking the fake TCP stack closed and
clearing registered sockets instead of panicking.
Refuse new sockets on closed stacks and let listeners recreate stacks
when the reader task exits.
Remove quinn-plaintext to fix connection errors caused
by different hash values across platforms.
On x64, maintain compatibility with quinn-plaintext.
Add config server client support for the C FFI and Android JNI bindings.
Reuse the existing easytier::web_client::run_web_client path and
NetworkInstanceManager; OHOS is unchanged.
Report successful remote config apply/delete operations through a
callback, with one JSON event per affected instance.
Keep the config server client and FFI data plane mutually exclusive: once
either side is in use, the other side returns an error instead of sharing
lifecycle state.
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.
1. Overview
This PR adds data plane APIs to easytier-ffi:
TCP Outbound:
- data_plane_tcp_connect
- data_plane_tcp_read
- data_plane_tcp_write
- data_plane_tcp_close
TCP Listener:
- data_plane_tcp_bind
- data_plane_tcp_accept
- data_plane_tcp_listener_close
UDP:
- data_plane_udp_bind
- data_plane_udp_send_to
- data_plane_udp_recv_from
- data_plane_udp_close
2. Key Changes
The main changes are focused on:
- easytier-contrib/easytier-ffi/src/lib.rs: Added FFI interfaces;
made ERROR_MSG thread-safe.
- easytier/src/gateway/socks5.rs: Bridges the data plane to the
existing Socks5 server logic.
- Added EasyTierUdpSocket, mainly wrapping ref-counting and
critical object (e.g., Socks5EntrySet) hold & drop logic,
and exposing common fields (e.g., local_addr).
- Extended Socks5Server functionality to expose TCP and UDP
socket creation interfaces for FFI calls.
- Other files: Mostly pass-through logic.
- Added a relatively large Go usage example.
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
Stop sharing PeerCenterServer state through a process-global map so local and foreign-network services cannot mix peer-center data when peer ids overlap.
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

Avoid resolving Url::as_ref() to the full URL string before TunnelScheme
conversion. Add regression coverage for owned/borrowed URLs and the UDP
IPv6 hole-punch branch condition.
