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.	2026-07-26 22:54:43 +08:00
KKRainbow	021f523431	refactor(core): separate portable core from native runtime (#2451) ... 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.	2026-07-26 15:41:55 +08:00
