Replace pnet_packet parsing and mutation across gateway packet paths with the existing smoltcp wire APIs. Preserve length validation, fragmentation classification, TCP flags, and checksum behavior while removing the core pnet_packet feature dependency.
Reject stale non-initiator OSPF sync sessions: only initiator requests may create missing sessions, and a rejection clears the old initiator role only when the remote session generation is unchanged. This fixes an unbounded RPC storm caused by a delayed route sync recreating a session after both peers relinquished the initiator role, with regression tests for session creation and response reordering.
Overhaul the WASI guest data plane for throughput and add the host
capabilities it relies on. The externally driven Tokio runtime now
runs its timer pre-turn only when a tracked deadline has expired,
and all WASI-reachable timers (STUN, port mapping, WebClient, UDP
flow cleanup) go through the portable time facade so conditional
timer driving cannot starve them.
Data plane:
- Move read/write deadlines onto TCP and UDP resources with one ABI
setter per direction, reuse a single expiration timer per
resource, and drop timeout arguments from the four hot data-plane
submissions (ABI v3). Checked absolute instants treat
unrepresentable finite timeouts as unbounded instead of panicking.
- Batch host traffic: vectored TCP frame writes combine queued
slices into one host operation, and reads request a bounded 64
KiB while retaining excess bytes in the stream buffer.
- Complete TCP writes inside the guest with cancellation-safe
writes, reporting the completed prefix before honoring
cancellation or timeout so hosts never replay bytes.
- Repoll smoltcp egress immediately on zero poll delay, enlarge
virtual UDP receive queues to 128 KiB payload with 128 metadata
slots, and bound UDP session receive buffers to 8 KiB plus one
byte while keeping oversized-datagram detection.
Host integration:
- Add optional algorithm-neutral AEAD seal/open imports with the
ring backend as fallback, and pin the ring AES-128-GCM wire vector
so the Go host stays interoperable.
- Forward instance events to hosts through one best-effort,
synchronous, non-blocking import.
- Add a repository-owned build entry point for the Go host artifact:
Binaryen 131 at -O4 with cached, SHA-256-verified official
archives.
Create easytier-core as the portable owner of configuration,
connectivity, tunnels, peer and routing state, gateways, management,
the data plane, and instance lifecycle. Keep operating-system
integration, native protocol engines, process startup, and presentation
in easytier behind explicit Host capability adapters.
Create easytier-proto to own schemas, generated RPC types, descriptors,
and feature-scoped protocol slices. Remove runtime protobuf reflection
from core while preserving unknown route-peer fields across forwarding.
Normalize instance construction through CoreInstance, CoreHostAdapters,
CoreProcessRuntime, and InstanceManager. Make the runtime config store
the only authoritative mutable configuration after startup.
Move the portable TCP/UDP data plane into core and extract a generic
OperationBroker for completion, cancellation, disposal, and capacity
accounting. Expose the session-based FFI v2 completion API and keep the
WASI guest ABI, wire schemas, and adapters with core.
Migrate CLI, GUI, web, FFI, Android JNI, OHOS, uptime, and mobile
consumers to the shared manager and core state. Add explicit user/web
config ownership and revision-aware web reconciliation.
Preserve configuration, wire, and management behavior while fixing
regressions discovered by the full platform and integration matrix:
- inherit advertised relay capabilities in foreign networks;
- refresh OSPF peer state immediately after runtime config changes;
- restore CLI GlobalCtx event output without forcing GUI logging;
- retain legacy encryption names and standalone RPC tunnel metadata;
- restore ICMP host composition and fragmented UDP handling;
- use portable 64-bit atomics on 32-bit MIPS targets; and
- retain discarded operations until late cancellation completes.
Validate the refactor across 45 GitHub checks, including Linux, macOS,
Windows, FreeBSD, web, GUI, Android, OHOS, feature profiles, and
three-node and subnet-proxy integration tests.
BREAKING CHANGE: internal Rust module paths are not preserved. Legacy
native data-plane APIs are replaced by the session-based FFI v2 API.
The dedicated Android data-plane wrapper is removed.
* feat(ffi): add async data plane API
* feat(ffi): add async data plane examples

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.
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.
Fix the issue where the Magisk module incorrectly matches the lookup main rule in Android 15's cellular network rules, causing data plane connectivity failure
Addresses security vulnerabilities in axios <1.13.5. Updates the
declared specifier to ^1.13.5 in all three frontend package.json
files and regenerates both npm and pnpm lock files (resolved: 1.13.6).

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.
