* 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.
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.
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.
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.
