* docs(security): add private reporting policy
Document supported versions and route vulnerability reports through GitHub's private advisory workflow.
Add English and Chinese responsible-use notices to the READMEs.
Closes#2544
* ci: skip unrelated pull request builds
Use pull-request-aware path filtering for required Core, GUI, Mobile, and Test workflows so they still publish required check contexts without launching expensive jobs for documentation changes.
Limit the optional OHOS pull request workflow to relevant paths.
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.
Fixes SOCKS5/port-forward handling for peer data packets
whose source endpoint was rewritten by the KCP or QUIC proxy path.
Keep SOCKS5 entry accounting consistent by centralizing insert/remove
operations, decrementing only for actual removals, avoiding underflow,
and resetting counts when entries are retained or cleared after IPv4 changes.
