* 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.
* bench: add packet bytes extraction Criterion benchmark
Adds a Criterion benchmark under easytier/benches/ covering
ZCPacket::payload_bytes and tunnel_payload_bytes at 1280/4096-byte payload
sizes, using iter_batched so ZCPacket construction stays in the setup phase
and is excluded from the timed region.
- Register the [[bench]] entry in easytier/Cargo.toml.
- Document the bench and PACKET_BYTES_* env vars in benches/README.md.
* perf: reduce packet buffer slicing churn
Replace BytesMut::split_off with Buf::advance in ZCPacket bytes
extraction paths (payload_bytes, tunnel_payload_bytes, convert_type,
drop_foreign_header) and in TunZCPacketToBytes, and simplify the
copy_from_slice in new_from_payload.
When the buffer is in its unique (VEC) representation, split_off promotes
it to the shared (ARC) representation, allocating a Shared control block
and bumping the refcount on every call, and pins the buffer in shared
mode. advance only mutates the in-place ptr/len/cap fields, avoiding that
allocation/refcount churn on the TX hot path. The byte data itself is not
copied by either path.
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
Remove quinn-plaintext to fix connection errors caused
by different hash values across platforms.
On x64, maintain compatibility with quinn-plaintext.
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
