* feat(mobile): add embedded iOS runtime API
Add a thin panic-safe C ABI crate for embedding no-TUN instances
on iOS. Expose lifecycle, status, JSON-RPC, string ownership, and
error handling.
Build device and simulator XCFramework static libraries on macOS.
Add exact named-instance deletion to the iOS and Android wrappers.
Cover wrapper lifecycle and the port-forward patch flow on host
targets.
* fix(gateway): recover TCP port-forward listeners
Release an unusable TCP port-forward listener after an accept
failure. Retry binding until the forward is cancelled. Keep the old
listener released while rebinding so mobile sockets can recover.
Expose opt-in iOS diagnostics for listener and connection events.
Trace configuration removal and adapter shutdown. Add tests for
recovery, release-before-rebind, and cancellation.
* feat(web): persist incremental managed config patches
Add a revision-CAS PATCH contract for managed configs while keeping
the existing Full PUT path for compatibility and recovery.
Apply Full and Patch mutations with their revision in one SQLite
transaction. Reject ownership conflicts and invalidate revisions on
alternate web-owned writes.
Document limits, failure semantics, rollout order, and verification.
Cover delta updates, conflicts, idempotency, and transaction rollback.
* feat(web): apply managed config patches to live sessions
Carry Patch fences and touched instance IDs into live sessions.
Reconcile only those instances when the applied revision matches the
Patch base. Fall back to Full reconciliation for gaps and restarts.
Invalidate the applied revision around every direct runtime mutation.
Fence revision advancement with the runtime cache epoch so stale
reconcile rounds cannot overwrite a newer invalidation.
Require deletion responses to confirm each requested instance before
advancing the revision. Raise the managed PUT and PATCH body limit to
32 MiB and return typed conflicts for publisher recovery.
* fix(core): retry transient accepted TCP errors
Keep TCP tunnel listeners alive when an accepted socket fails during
upgrade with a retryable connection-state error.
Share the retryable I/O classifier with the socket listener. Cover a
rejected connection followed by success and propagation of permanent
errors.
* feat(core): add internal Peer Relay edge projection
Derive the local advertised OSPF row from physical adjacency and transport-authenticated credential relay coverage. Keep full local adjacency only in the temporary SPF snapshot so direct destinations retain a fallback route.
Leave Peer Relay disabled at the public configuration seam. A follow-up change can expose the preference without coupling route projection to credential reauthorization.
feat(config): expose Peer Relay routing preference
Add prefer_peer_relay to public protobuf, TOML, management patch, and
hosted runtime surfaces.
Read the preference from live peer context so runtime config updates take
effect. Refresh authenticated peer metadata when the option is enabled.
Cover dynamic enable and disable in a five-node, dual-admin credential
topology, including forwarded relay coverage and local fallback.
A half-open handshake consumed the only smoltcp listener socket, so
other clients were rejected until its timeout. Closed listener sockets
could also remain unusable after a network interruption.
Register logical TCP listeners with the reactor without preallocating
socket slots. Allocate one temporary smoltcp socket for each new SYN;
repeated SYNs reuse the existing connection. Limit each listener to
sixteen pending handshakes or completed connections.
Batch ordinary ingress packets through smoltcp and scan listener state
once per batch. Before admitting a SYN, advance timers, reclaim stale
pending sockets, and flush queued packets. Process only a newly
allocated socket's SYN separately to preserve packet order.
Keep the global tuple lookup off unmatched and full-listener rejection
paths. Promote established connections to the normal timeout, reclaim
closed connections, and transfer accepted sockets to streams.
Keep one long-lived logical listener in SmolTcpStack and cover
concurrency, retransmission, timeout recovery, capacity, and cleanup in
tests.
* refactor(credentials): centralize grant policy
Represent ACL groups, relay permission, proxy CIDRs, and reuse as one
internal credential grant shared by generated, imported, managed, and
attached credentials. Normalize proxy CIDRs at construction while
preserving the flat credential storage schema.
Reuse one managed credential adapter for protobuf/TOML projection and
patching so defaults and future fields have a single mapping authority.
* fix(credentials): normalize grants loaded from storage
Run persisted grants through the same CIDR normalization used by new and
managed credentials. Reject invalid stored CIDRs through the existing
storage-unavailable path and include the credential ID in the error.
Cover whitespace migration and invalid legacy data with regression tests.
* feat(credentials): manage declarative credentials through TOML
Make managed credentials part of the canonical TOML configuration and
load them before peers can authenticate.
Reuse ConfigRpc hot patches to durably replace the configured credential
set without restarting the instance. Serialize credential mutations so
base, managed, and ephemeral keys cannot race into conflicts.
Remove the managed overlay file format, digest protocol, capability
negotiation, force reconciliation, and database CAS machinery. Redact
credential secrets from debug output and management events. Write
credential-bearing files atomically with private permissions.
* fix(core): release JoinSet reapers with their owners
Pass weak task-set references into background reapers so they cannot
retain the JoinSet they are meant to collect. This lets stale smoltcp
bridge tasks terminate when an IPv4 generation is replaced.
Add ownership and TCP generation-replacement regressions covering the
production port-forward failure.
* feat(vpn): hot add/remove WireGuard portal clients without restart
WireGuard portal clients were frozen at instance construction: the
engine slot maps, host key table, and PortalModule state were all
immutable after startup, so any client change required recreating the
whole instance and dropping every established session.
Wire dynamic client management through the existing config-patch
channel (ConfigRpc.patch_config -> apply_config_patch), following the
same pattern as connectors, port forwards, and proxy networks:
- proto: InstanceConfigPatch gains repeated VpnPortalClientPatch
(Add/Remove/Clear by client name)
- engine: slot maps move under an RwLock with a free-index allocator;
add_client/remove_client recycle indices, mark removed slots retired,
and expire active sessions so Core tears down the attached peer via
the regular channel-close path (credential revocation and disconnect
events included); untouched clients keep their sessions intact. The
retired flag is re-checked under the session lock so a datagram that
races with removal cannot resurrect a session
- host: WireGuardPortalHost derives keys deterministically per name
(HKDF), keeps a mutable client table for render_client_config, and
forwards updates to the live engine; changed clients are re-added so
they re-handshake into a fresh generation with the new virtual IP or
groups
- PortalModule: client set, statuses, and session locks become shared
mutable state; run_session resolves clients from the shared map at
accept time; update_clients() validates against a caller-supplied
runtime snapshot. An empty client set is legal in every lifecycle
stage, so clearing all clients never produces a configuration that
fails instance recreation
- config_patch: apply_vpn_portal_client_patches mutates the candidate
TOML; the sub-patch runs last and is deep-validated and hot-applied
before the candidate commits, so a rejected client set leaves neither
the shared model nor the live portal changed, and validation sees the
fully patched state including routes and node IPv4 from the same
request. Rejects patches when no portal is configured or a removed
client does not exist
- cli: vpn-portal add-client/remove-client/clear-clients subcommands
Tests: engine index recycling, module update validation/state/host
notification, TOML patch application, and a three-node integration test
that adds a second WireGuard client live, removes the first while the
second stays online, and asserts rejected patches leave the shared
model unchanged.
* feat(web): reconcile WireGuard portal client edits as hot patches
The web console reconciles desired network config against the running
instance and patches it in place when possible. VPN portal changes were
not part of that: any client edit made the base configs differ, so every
save recreated the instance and dropped all established sessions.
Exclude vpn_portal_config from the base comparison and diff its clients
by name instead. Client add/remove/change now produces
VpnPortalClientPatch entries (removals first, changed clients as
remove+add) applied through the existing PatchConfig channel. Listener
identity changes (address or private key) and enabling or disabling the
portal still fall back to a full instance recreate, since those change
the listener lifecycle.
* feat(web/gui): map portal client patches to frontend RPC backends
Extend the RemoteClient seam with add/remove/clear VPN portal client
operations so frontend hosts can drive the same PatchConfig channel as
the CLI. There is deliberately no dedicated editing UI: the config form
stays the single editing surface (aligned with port forwards), and
these methods exist for programmatic and future use.
- web console: JSON proxy-rpc to ConfigRpcService.patch_config with
VpnPortalClientPatch entries (pbjson string enum actions)
- desktop GUI: patch_vpn_portal_clients tauri command forwarding the
same patch through the typed ConfigRpc client
* feat(peer): support protocol-agnostic attached peers
Add locally attached peers backed by independent, peer-level portable
managers and authenticated in-process ring connections. Carry trusted
connection provenance through packet admission so attached relay
privileges cannot be forged through packet headers.
Let every peer manager own ACL loading, sanitized policy updates, route
refresh, and runtime cleanup. In Secure Mode, grant attached identities
ephemeral credentials instead of sharing administrator and group secrets.
* feat(vpn): add reusable attached-peer portal runtime
Add a protocol-neutral portal runtime that converts authenticated client
sessions into attached EasyTier peers. Own per-client generations,
status, packet forwarding, address translation, and peer cleanup without
knowing the transport protocol.
Add transactional IPv4 source and destination rewriting with correct
IPv4, TCP, UDP, ICMP, and quoted-packet checksum updates. Keep the old
production portal path temporarily active until the WireGuard adapter is
migrated in the next change.
* feat(wireguard): attach named clients through peer portal
Replace the monolithic WireGuard portal with a native adapter that owns
key derivation, UDP demultiplexing, reauthentication, roaming, and
bounded per-client packet queues. Hand authenticated sessions to the
generic portal runtime for peer lifecycle and IPv4 translation.
Move portal configuration into the core instance model, require a
dedicated server key, and preserve existing listener, CLI, and runtime
configuration behavior. Reject runtime address conflicts before
publishing shared configuration.
* feat(vpn): expose per-client portal status
Project configured clients and their runtime state through the portal
RPC, including generated client configuration, listener, peer identity,
endpoint, tunnel address, ACL groups, and errors. Keep private client
configuration out of the broad instance-info response and expose the
explicit RPC through the CLI and Tauri bridge.
* feat(vpn): add portal configuration to web clients
Expose WireGuard portal listener, key, client, ACL group, and runtime
status fields in the shared frontend library, Web dashboard, and Tauri
client. Preserve UUID and uint64 values across protobuf JSON
boundaries, keep dynamic client editor rows stable, and document the
portal workflow.
* test(vpn): cover multi-client and roaming WireGuard portals
Add two three-node integration tests for the WireGuard VPN portal.
The multi-client test connects two kernel WireGuard clients from
separate network namespaces, verifies per-client connectivity to mesh
nodes, and exercises cross-client traffic that runs the IPv4 source
and destination translation in both directions. A TCP echo exchange
through the portal additionally covers the TCP pseudo-header checksum
rewrite path that ICMP-only ping tests miss, and portal status
snapshots must report both clients online with distinct peer ids and
correctly learned tunnel addresses.
The roaming test swaps the client namespace address (delete the old
address, then add the new one) so the kernel WireGuard source cache is
invalidated and the client keeps sending under the same session from
the new source, exactly like a real network change. The portal must
update the client endpoint on the same peer id via the data path
(same generation, no re-handshake, no detach/reconnect) while
connectivity to mesh nodes is preserved.
Supporting changes: run_wireguard_client now takes an interface name,
and the shared namespace topology gains net_f (10.1.2.5) on the portal
bridge for the second client.
Add a try_recv() fast path to recv_packet_from_chan(): if a packet is
immediately available, return it without parking the task. Only when
the channel is empty do we fall back to recv().await.
This benefits all callers of recv_packet_from_chan() including
start_peer_recv, virtual_nic, foreign_network_manager, and instance.
* feat(peer): echo liveness probes on data traffic
Advertise a liveness-echo capability during classic and Noise
handshakes. After a ping failure, tag outgoing peer packets with a
short probe token and accept only the matching echoed token as
round-trip proof.
Keep one ping request outstanding and coalesce scheduler triggers so
high traffic cannot reorder timeout results. Preserve one-way failure
detection because unrelated ingress never clears the loss counter.
* test(three_node): relax disconnect wait for sequential pingpong
proxy_three_node_disconnect_test assumed the old pingpong timing,
where overlapping pings failed fast and the connection closed well
inside the 11s wait (see the old [4, 9)s comment).
The liveness-echo change keeps one ping outstanding: each failure
now takes a full 2s timeout, so the fifth consecutive failure and
the connection close land at ~11s. Both proto variants timed out at
the 11s bound in CI. Widen the wait to 15s and update the timing
comment.
tcp_stun_servers explicitly controls TCP STUN servers.
If tcp_stun_servers is not configured, TCP STUN falls back to configured stun_servers.
If neither is configured, TCP STUN uses the built-in default TCP STUN list.
Empty lists explicitly disable the corresponding STUN server list.
Empty CLI/env overrides now clear existing configured STUN servers instead of appending nothing.
* feat(credentials): support managed credential synchronization
Allow managed callers to upsert credentials with an exact ID, secret,
permissions, reuse policy, and expiry.
Return non-secret attributes plus a public-key fingerprint so callers can
verify relay credential consistency.
Persist imported credentials atomically and preserve identity and expiry
across restarts.
* fix(credentials): make managed upserts durable
Write the candidate credential snapshot before committing it to memory.
Propagate storage failures so controllers can retry instead of observing
false convergence.
Cover a transient storage failure to verify that memory stays unchanged
and the retry persists the credential.
* fix(credentials): atomically replace stored snapshots
Define CredentialStorage::store as an atomic replacement boundary and
use atomic-write-file in the management adapter. This keeps the last
committed credential JSON readable when a replacement fails.
Cover replacement of an existing credential snapshot and keep the
dependency scoped to the management feature.
* feat(ohos): complete nearby console integration
Use the core management RPC surface for ephemeral nearby deployments, harden session lifecycle and packet validation, support tunnel-to-NIC packet conversion, and timestamp HarmonyOS traffic samples.
* fix(core): prefer verified UDP hole-punch paths
Treat zero latency as unmeasured so a newly admitted UDP path cannot replace a working relay before liveness is confirmed.

Co-authored-by: FrankHan <frankhan@FrankHans-Mac-mini.local>
Add a native EasyTier proof-of-concept binary with TCP and UDP
transports, TUN, UDP hole punching, AES-GCM, and a read-only RPC
portal.
Introduce a release-derived mini profile and musl linker policy so
x86_64, big-endian MIPS, and little-endian MIPS stay below the strict
5,000,000-byte target without UPX.
* feat(wasi): expose protobuf RPC request ABI
Add an instance-scoped asynchronous RPC session backed by the shared
operation broker. Reuse the existing dispatcher and management handlers.
WASI hosts can call PeerManageRpc and ConnectorManageRpc with the same
protobuf payloads as easytier-cli.
Export ABI version, submit, take, and free functions. Bind selectors to
the WASM instance handle and keep method errors in RpcResponse. Enable
management RPC explicitly in the Go-host WASM build.
* fix(gateway): serialize UDP client eviction
Serialize UDP client admission across forwarding rules so only one
eviction can claim and wait for a released semaphore permit. Retry
when cleanup concurrently removes the selected client.
Add a multithreaded regression test for the permit handoff while the
evicted client is still referenced.
* fix(gateway): publish UDP client admission atomically
Hold the admission guard through client and response-task publication
so a concurrent eviction cannot leave an orphan task holding the slot
permit.
Open the data-plane flow before entering the critical section and extend
the multithreaded regression test across the publication window.
Add a small Vite workspace that builds and publishes independently
of the dashboard. Reuse frontend-lib for the form and expose the
existing NetworkConfig conversions through wasm-bindgen.
Initialize the Aura theme in the standalone entry, detect the browser
language, and provide a persistent selector in the form header. Present
Generate Config and Copy Config as the page actions.
Keep the shared network secret field fluid so both form columns align.
Bundle the generator under dist/config-generator in the dashboard
artifact while preserving its standalone build output.
Build the optimized WASM module with the project and remove the
API-backed generator route from the dashboard.
Require matching pong responses before resetting consecutive liveness
failures so half-open direct connections leave the peer map.
Carry latency-first policy on relay handshakes and route replies around
stale direct peers, including handshakes started during decryption.
Store peer-center reports as atomic per-peer snapshots and include
topology costs in the digest so removals and latency updates propagate.
Drop data packets at a saturated host egress boundary instead of
blocking the shared peer packet router and shutdown path.
Add regressions for asymmetric traffic, relay ACK routing, peer-center
invalidation, and bounded host egress.
Replace periodic refill tasks with on-demand accounting to avoid waking
idle token buckets.
Keep balance, refill time, and fractional credit in one locked state so
concurrent consumers cannot observe partially published refills or
exceed the configured burst capacity. Track credit in nanoseconds and
discard excess credit at capacity to preserve precise limiter behavior.
Use a one-second default burst capacity to preserve the existing
limiter behavior while supporting explicit capacity configuration. Keep
limiter capacity and fill rate in a local config instead of an unused
protobuf message.
Charge only logical EasyTier data payload, unwrap foreign network
packets before accounting, and leave control traffic outside the
limiter. Reject forged payload lengths by accounting from actual packet
boundaries.
Split oversized blocking consumes into capacity-sized chunks and cover
concurrency, refill precision, burst caps, payload accounting, and
bandwidth integration behavior.
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.
* perf(stats): avoid per-update clock reads
Perf profiles show quanta::get_now consuming 2.9-4.3% of data-plane
CPU because every counter update refreshes a high-resolution timestamp.
Track metric activity with the existing 60-second cleanup cadence instead.
Relaxed 32-bit epochs preserve the three-minute retention window, support
32-bit targets, and remove repeated clock reads from packet processing.
* perf(data-plane): reduce per-packet synchronization
Perf profiles showed per-packet config Arc cloning, bounded-channel
permit futures, duplicate peer lookups, and default connection UUID
lookups consuming CPU in both TCP and UDP data paths.
Borrow stable config snapshots, use nonblocking channel fast paths with
the existing backpressure fallback, reuse direct peer lookups, and cache
the selected connection while preserving close and reselection behavior.
Add focused tests for channel backpressure and cached connection
invalidation.
* fix(peer): serialize default connection cache updates
The profile-guided default connection cache could republish a connection
after the close task removed it, leaving a stale cache while another
connection remained live.
Serialize only cache-miss selection/publication and connection removal.
The per-packet cache-hit path remains lock-free, while close and selection
can no longer race to resurrect a removed connection.
* perf(core): make data-plane idle check constant time
Avoid scanning every DashMap shard for each peer packet when no data-plane flows are active.
Publish the flow count before insertion and release it after removal so an Acquire load is a safe O(1) idle signal. Reject count overflow and underflow instead of silently saturating.
* test(perf): add repeatable two-node netns benchmark
Create isolated underlay namespaces, pin both EasyTier cores and iperf3 endpoints, and measure a single TCP flow in both directions over either UDP or TCP peer transport.
Keep every iperf3 JSON result and emit directional medians while cleaning up processes and namespaces on every exit path.
* perf(tcp): preserve native owned stream halves
Let each VirtualTcpSocket adapter consume itself into independent read and write halves. Portable adapters retain the generic shared split as a default.
Use lock-free Tokio owned halves for native TCP and Unix streams so tunnel I/O no longer takes the generic split mutex on every poll. Cover full-duplex traffic and write-half shutdown.
* perf(packet): preserve ownership across the Host seam
Introduce an opaque, move-only HostPacket that retains core packet storage while exposing only the raw IP payload. Clear private headers before handing storage back to a native TUN adapter.
Use an ownership-preserving bounded channel for native ingress and egress. Keep explicit copy adapters for Vec and WASI boundaries, and verify allocation identity, backpressure, shutdown, and end-to-end delivery.
* perf(udp): preserve packet ownership through sessions
Carry EasyTier tunnel packets through UDP session queues as owned values. Reuse the existing tunnel header for session framing instead of copying payloads into a second packet and rebuilding them on receive.
Keep completion delivery for the public datagram socket API while removing the unused completion channel from streaming tunnel sends. Avoid the unconditional receive-side clone before QUIC routing is known.
* perf(peer): publish packet filters as immutable snapshots
Replace per-packet async and synchronous registry locks with ArcSwap snapshots. Permanent filters now need no activity checks, while managed registrations retain explicit acquire/release visibility.
Closing a managed registration marks it inactive before atomically removing it. Existing snapshots keep in-flight filters alive, and registration mutations prune inactive entries while preserving newest-first order.
* perf(instance): give native hosts direct packet egress
Let the core create one bounded HostPacket channel and transfer its receiver directly to a PacketEgressHost during startup. Native TUN runtimes now consume that receiver without the intermediate PacketSink channel and forwarding task.
Keep PacketSinkEgress as the compatibility adapter for callback and test hosts, and make receiver installation one-shot across desktop, mobile, and disabled runtimes.
* perf(crypto): restore accelerated native AEAD backends
Move Ring and OpenSSL implementations behind the core Encryptor seam.
Portable builds continue selecting only supported backends.
Restore historical precedence: OpenSSL, Ring, then RustCrypto. Keep
backend availability consistent across secure transports and cover
fixed-nonce wire compatibility between implementations.
* perf(udp): receive native datagrams into owned buffers
Extend the portable UDP socket seam with an owned-datagram receive path.
Keep a compatible default for portable hosts. Native Unix sockets write
recvmsg output directly into the final BytesMut allocation.
This removes the per-packet stack-to-heap copy introduced by the portable
socket boundary without exposing native socket resources to core.
* perf(data-plane): remove portable hot-path overhead
Restore native throughput lost while generalizing the host and UDP
session layers.
Read packet policy once per send, update traffic counters through
registry guards, and preserve packet ownership while UDP dispatch
borrows stable session state.
Move UDP shutdown monitoring into a control task so forwarding avoids
a select future per packet. Bound native datagram storage to 8 KiB,
reject oversized sends, and drop truncated Unix receives.
Keep accelerated AEAD selection warning-free when portable crypto
features are also built. Cover session bounds, truncation, and idle
shutdown with regression tests.
* fix(udp): preserve portable datagram receive semantics
Keep the public portable receive capacity at the theoretical UDP
maximum instead of silently shrinking it to the native fast-path limit.
Apply the 8 KiB session boundary after a complete portable receive,
so Windows cannot turn an oversized datagram into a fatal listener
error and other adapters cannot dispatch a truncated prefix.
Cover dropping an oversized packet while the same portable socket
continues to deliver the following valid datagram.
* fix(ci): align feature gating with backend selection
Compile the Ring implementation in production only when OpenSSL is not
selected, while retaining it for cross-backend unit tests.
Remove stale test imports and assert UDP dispatch results so the strict
workspace Clippy job passes without suppressing diagnostics.
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.
* support network identity for instance
* introduce foreign network
foreign network allow a node serving as one public node. other nodes can
connect to this node to discover peers and exchange route info.
