rustdesk	ac96ccac85	review: keep the 30s watchdog hard, and let Android's picker hold the reconnect ... Timing the watchdog off receive progress gave away its upper bound. A fragment bumps the counter as it arrives, ahead of the framing checks that would reject it, so a peer sending one `FRAG_MORE` every twenty seconds and never a `FRAG_END` refreshed the deadline forever while the reassembly buffer grew toward `MAX_FRAME_LENGTH`, a gigabyte away. What it bought - a clipboard image that takes longer than thirty seconds to arrive is not a dead peer - is a pre-existing problem that predates this branch and can be fixed on its own. Receive progress goes back to the one job it was added for, which needs no deadline of its own: telling a transport that has gone quiet from one that is still delivering, so ICE's disconnected hint is not acted on mid-transfer. The Android document picker suppresses a `Connection Error` while it is open and remembers to reconnect once it closes. The peer-gone break reconnects under `restarting-show` with a `Connecting...` title, which matched neither half of that test, so an eight-second stall behind an open picker - Doze and background throttling produce them - threw a dialog up behind the picker and lost the deferred reconnect. It is now named there by its own title rather than by its type: an explicitly restarted remote device sends the same type from a path this leaves alone, on every transport, and deferring that one too would be a change to sessions this has no business touching. The two limits are still not hard upper bounds, and the comment saying so was wrong about why. A send is awaited inline in this loop, so one in progress delays the tick that checks them - bounded on WebRTC by the timeout the stream was built with, not bounded at all on KCP, whose framed stream is constructed with none. The 30s watchdog beside it shares the loop and the same delay. Left alone deliberately. `restarting-show` reconnects without the backoff its `restarting` sibling uses, which can loop while each round gets far enough to establish a session and then loses the transport within eight seconds; a cooldown there would also delay the recovery this exists for when a peer really does come back, and the loading it shows can be cancelled. And the KCP limit reads an accumulated silence rather than a transient hint, so unlike the WebRTC grace it needs no second sample to confirm - one would only move eight seconds to nine.

rustdesk	e6d318488b	review: keep the legacy UI's retrying error when the peer goes silent ... `restarting-show` is a Flutter control event; Sciter has no case for it and falls through to a plain dialog, which `check_if_retry` marks non-retryable because its type is not `error`. So on that build the new detector would have replaced a timeout that reconnects on its own after 30s with a dialog waiting for a click at 8s - a regression for the one path this was meant to shorten. Send it the message the timeout already sends, so its behaviour is unchanged apart from arriving sooner.

rustdesk	fdc83171c9	review: reject a disconnected cached session, tidy the detector ... hbb_common: `is_reusable_for` now also rejects a session ICE reports Disconnected, so a caller is not handed one that already carries the hint; and the receive-progress test no longer races `next()` against a sleeping sibling. Here: the `is_some()` guard on the progress comparison was dead, since a transport answers `None` for its whole life and `None != None` is already false. The parting-send deadline is a `Duration` like every other constant around it rather than bare milliseconds. And the comments are cut back to what is not already evident from the code they sit on.

rustdesk	1a40189e21	review: time the inactivity window off receive progress, bound the parting send ... Two things the review found, both on the controlling side. The 30s inactivity window still ran off completed messages alone, so the probe added for the fast path did not fix what it was added for: a message larger than the transport's fragment size yields nothing until its last fragment, and a peer sending one steadily was still timed out mid-transfer. It is now timed off whichever is later, a completed message or receive progress. Transports that report no progress leave that at its starting value, so nothing else moves. The parting close-reason send for KCP waited on send capacity with no deadline of its own, and a queue a dead peer will never drain held the finished session's thread until the endpoint reaped the connection a minute later. Bounded once the peer has been declared gone. Still attempted rather than skipped: if the loss was one-way the peer does receive it, and drops its side immediately instead of waiting out its own timeout - which is also the one case where the note below resolves itself. Recorded from the same review, for the case none of this targets - a peer that is alive behind a path that broke for five to ten seconds and then healed. Giving up cannot deliver a close there, because the path is still down at that moment, so the controlled side keeps the old connection until its own 30s expires. For up to twenty of those seconds it holds two authorised connections: its connection manager lists both, and the stale one reports a growing delay that pins the shared frame rate low for the new one. Input is unaffected throughout and both recover once the stale connection goes, so this trades twenty-two seconds of a frozen, uncontrollable session for a controllable one that looks wrong for a while. Closing the displaced connection is controlled-side work and belongs with the rest of it, not here.

rustdesk	860ffe77a8	kcp: recover from a silent peer on the endpoint's own clock ... KCP is the other transport with nothing to receive when the peer dies, and it was the slower of the two: its endpoint reaps a connection only after 60s without a packet, which is past the 30s inactivity timeout above it, so in practice nothing but that timeout ever noticed. The endpoint already tracks when each connection last heard from its peer and now exposes it, so this reads that rather than anything derived from the session loop - it keeps answering while that loop is busy sending. Its liveness ping now goes out about every 2s rather than every 10s, so silence means the peer rather than an idle link, and eight seconds of it is several missed pings. Same threshold and the same recovery as the WebRTC half, so a user sees the same thing on either transport.

rustdesk	70e2893e57	webrtc: recover from a silent peer in about 8s instead of 30s ... A controlled peer that is killed, switched away by a user switch, or rebooted leaves no trace on a UDP transport: there is no reset to receive, so the session sees silence, and only the 30s inactivity timeout ends it. By then the remote machine may have finished rebooting and be reachable again, while the user has been watching a frozen frame the whole time and is then told the peer reset the connection. ICE already knows sooner. It reports Disconnected about 5s after it stops hearing from the peer, from its own task, so it stays accurate even while this loop is busy sending. That state is transient by design - a Wi-Fi roam or a sleep/wake recovers from it - so it is treated as suspicion, not as death: three more seconds with the transport receiving nothing, and the session reconnects. Receive progress cancels the suspicion, so a peer that is merely slow, or one ICE was late to clear, is not dropped. This only reaches the existing recovery sooner; it does not replace it. The first reconnect goes out immediately and, if it fails, falls into the same retry the UI already applies to any unexpected disconnect. The restart reconnect event is reused deliberately: it is what asks for exactly that, with no error dialog in front of it, and the UI shows "Connecting..." for it rather than anything about restarting. Its five-minute grace stays reserved for a restart the user actually asked for - silence is no evidence of a reboot. The 30s timeout is unchanged and still backs every transport. TCP and WebSocket are untouched. The controlled side is untouched: it detects a dead controller on the same 30s, which wastes some capture but nothing a user sees.

cui fliter	5228f91982	fix(screenshot): keep cached image when saving fails (#16120) ... Signed-off-by: cuishuang <imcusg@gmail.com>	2026-09-09 07:46:19 +08:00
RustDesk	b50fde6910	add the base crate and repoint the moved modules at it (#16107) ... * add the base crate and repoint the moved modules at it `libs/base` (crate `base`) takes the parts of hbb_common that only this app uses: `fs`, `platform`, `keyboard`, `message.proto`, and 145 of the 177 `config::keys` constants. hbb_common keeps what the server names, and the 32 keys it reads itself are re-exported from `base::config::keys` so call sites still see the full set through one path. Sources move verbatim. The only edits inside them are `crate::` prefixes that now have to say `hbb_common::`; `keyboard.rs` and `platform/windows.rs` are byte-identical. The crate stays on edition 2018, the edition the moved code was written under. `log`, `lazy_static` and `anyhow` become direct dependencies so the bare paths in that code resolve exactly as before, and its winapi features are spelled out rather than left to feature unification. Two call sites outside Rust and Cargo had to follow the move: the Android protobuf source dir, which still pointed at hbb_common/protos for message.proto, and the three AGENTS.md entries that named hbb_common for options, protos and file transfer. `scrap`'s `drm` feature now forwards to `base/wayland_probe`. Left pointing at hbb_common it would still have compiled, silently dropping the Wayland socket-probe fallback, so that forward is verified by a build with and without the feature. `config::keys` carries a test asserting its names stay disjoint from the ones hbb_common kept: the glob re-export and the local constants share a namespace, and Rust prefers the local item silently, so a name added to both sides would otherwise let client and server disagree with no diagnostic. Verified: macOS and Linux, debug and release, `--all-targets`; the 177 key constants diffed name-for-name and value-for-value; the generated protobuf types compared before and after; every `#[cfg]` gate on a moved import checked against its original; and every file that was `rustfmt`-clean before this change still is, compared against master file by file. Windows is checked by inspection only -- it cannot be compiled here. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EZ49AbZJYfm8NTp5yDPMab * one `use` per crate, and write the rule down `fs.rs` came out of the move with two ungated `use hbb_common::` statements, because the original single `use crate::{...}` had to give up `message_proto` to the new crate and the rest was left in a second block. Fold it back into one. A scan of the whole tree for the same shape finds nothing else: every other file with more than one top-level `use base::` or `use hbb_common::` is split by a `#[cfg]` that does not cover the whole block, or by `pub use` next to `use`. Those are the cases that cannot merge, so AGENTS.md now states both the rule and the exemption.

RustDesk	ae6af2de43	Webrtc (#15684) ... * feat: add rendezvous WebRTC signaling fields * feat: route WebRTC ICE on controlled side * feat: race WebRTC as a direct transport enhancement * fix: route WebRTC ICE through rendezvous paths * feat: WebRTC transport racing, DTLS identity binding, and pc-leak fixes - prefer-P2P racing (race_transports_prefer_webrtc) across punch and RelayResponse; ICE bridge with 400ms candidate resend - controlled-side answerer and ICE routing; sign local DTLS fingerprint into SignedId, controller verifies the binding fail-closed - fix pc leaks: close_webrtc() on insecure-decline paths (io_loop, port_forward); compute direct before disarming the offerer guard - point hbb_common to the WebRTC data-plane commit 9f5a296 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix: preserve WebRTC transport preference * feat: decouple WebRTC from UDP punch, route controlled signaling over TCP - the WebRTC offer now rides any punch request; only an offer-less request may close and reuse the rendezvous socket for TCP punching (request_allows_tcp_punch replaces the udp_port-based invariant), with a separate offer-less request racing as the TCP fallback - WebSocket mode no longer disables WebRTC — ws only tunnels the signaling/relay legs while ICE stays the only P2P path there; SOCKS proxy still disables it (ICE would bypass the proxy and leak the real IP) - controlled side: WebRTC-only punch replies and trickled ICE candidates go over dedicated TCP connections to the rendezvous server instead of the UDP mediator channel, for ws/TCP-only hbbs deployments; drop the now-redundant rz_sender plumbing and the 400ms candidate re-send on that leg - guard is_udp handling against responses to requests that advertised no udp_port; skip the IPv6 socket bind under force-relay - test_udp_uat: drop the STUN port race — the punch port must come from the rendezvous server's TestNatResponse observing this socket's mapping, a STUN probe from another socket can advertise an unreachable port - bump hbb_common (webrtc 0.13 MSRV pin rationale + upgrade checklist docs) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: KCP/UDP resilience to ICMP resets; optional KCP congestion control - treat ICMP-driven UDP socket errors (WSAECONNRESET 10054 on Windows, ECONNREFUSED on Linux) as packet loss in punch_udp and the KCP pump instead of tearing the session down; KCP retransmits through them and a truly dead link is still reaped by the pong/app-level timeouts - resolve STUN hostnames via tokio::net::lookup_host so DNS never blocks a runtime worker; fix the inverted non-IPv4 error message - add enable-kcp-congestion-control option (default on): switch the turbo profile to nc=0 so brief loss on constrained links no longer spirals into stalls; sender-side only, no wire negotiation - pin kcp-sys to the rustdesk-patches branch: upstream main lost the RustDesk patches on the EasyTier sync, and this branch also wires set_kcp_config_factory into connection setup, making the option effective Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: carry switch_code through WebRTC relay fallbacks after rebase The rebase onto master (switch-code feature) added an 8th request_relay parameter; pass the interface's switch code from both WebRTC->relay fallback paths so a role-swap session survives the fallback. Also drop a duplicate bindgen 0.72.1 entry the Cargo.lock merge produced. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01ExUfAkYbq8UC9pQCiLy8TQ * fix: don't let the preferred branch's own relay preempt a direct fallback race_transports_prefer_webrtc committed any success from its first argument outright, on the assumption that it is the WebRTC connect. It is not: the call site passes a whole punch attempt, which internally falls back to request_relay when its direct transports fail. That relay was therefore committed instantly while the offer-less fallback's TCP punch was still in flight — inverting the preference this function exists to enforce, since the is_p2p predicate the caller already supplies was applied only to the `others` branch. Apply it to both branches: a direct result from either side still commits immediately, and a relayed result from either side is held for the window so the other side can land something direct. Also commit a held connection when the surviving branch errors, which the previous code only did on the first branch's failure path. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01ExUfAkYbq8UC9pQCiLy8TQ * fix: evict the oldest pending ICE candidate, not the newest Candidates arrive in gathering order — host, then srflx, then relay — so a full buffer was discarding exactly the ones that traverse NAT while keeping host ones that only work on a shared LAN. Evict from the front instead. Also document why the controller's ICE bridge must not reconnect on error, in contrast to the controlled side's per-candidate retry: its socket address is the return route itself (mangled into PunchHole.socket_addr, echoed back in IceCandidate.socket_addr, resolved through tcp_punch), so a reconnect would arrive from an address no route points at, and the server drops the old entry when the connection closes. Once it dies both directions are dead, and abandoning WebRTC is the correct response rather than retrying. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01ExUfAkYbq8UC9pQCiLy8TQ * fix: bound log volume on sites whose rate a peer or retry loop controls Debug output goes to the log file, so a site that fires per received message or per retry lets someone else decide how much a machine writes to disk. The WebRTC work added the first such sites. - KCP io loop: absorbing ICMP errors as packet loss made a broken socket write ~100 lines a second for the 60s until the pong timeout reaps it. Log by run instead: one line when a run starts, one per ~5s while it persists so a stuck socket stays visible, and one on recovery with the total. - punch_udp: the recv error retries every 10ms for up to MAX_TIME, so one line per occurrence wrote thousands per punch. Log the first, report the count in the timeout message. - ICE candidate paths (client, mediator): the peer sets the candidate rate and the rendezvous route carrying them needs no prior punch, so throttle to one line a minute each with the suppressed count. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01ExUfAkYbq8UC9pQCiLy8TQ * fix: the KCP io throttle reset itself every cycle, so it never throttled The send and recv arms shared one counter, and an ICMP error on a connected socket is reported once and then cleared — so the steady state is an alternation: the send succeeds and clears the counter, the next recv reports the error and finds the counter at 1, and logs. Every error still wrote a line, at the ~100/s the previous commit set out to stop, while the persistent-failure and recovery branches were unreachable. Use one LogThrottle per direction instead of a hand-rolled counter. That removes the shared state the bug lived in, drops a third throttling mechanism in favour of the one already added, and leaves the surrounding `if let Err` untouched rather than reshaping it into a match. Also fix test_udp_uat's socket-error arm, the untreated twin of the punch_udp site: it had no backoff at all, so a persistent error re-armed recv immediately and spun the loop at CPU speed, one warn line per iteration.

Split the flag. LoginConfigHandler now tracks policy_relay (the force-always-relay option, an explicit relay request — /r ids and retry-via-relay included — and proxy) separately; force_relay stays policy_relay || use_ws() and keeps governing the classic paths, so non-ws behavior is unchanged everywhere: - the offerer's existence and ICE policy follow policy_relay: under pure ws the offer gathers every candidate type and may go direct; under relay-by-policy it stays Relay-only ICE, TURN-gated, exactly as before; - the RelayResponse race applies the prefer-P2P window under ws (a direct ICE path is worth delaying an already-ready relay for) while policy relay keeps first-success semantics; - the request carries webrtc_all_ice (hbb_common 64b54ab) so the controlled side knows the offer is full-ICE: it answers with full ICE and no TURN requirement, while offers without the bit keep today's relay-only answer path on every version-skew combination.

Lock-only change: cargo update -p kcp-sys also re-picked libloading's windows-targets between two versions already present in the lock; that was reverted to keep this commit to the one line it is about. cargo metadata --locked passes on the result. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * ws: read the all-ICE declaration from the offer envelope, drop the proto field Companion to hbb_common 68d2729: the full-ICE declaration now lives as an `ice_policy: "all"` key inside the webrtc:// envelope, so the request assembly no longer sets webrtc_all_ice and the controlled side asks the envelope (endpoint_declares_all_ice) instead of a PunchHole field. The rendezvous server carries the offer opaquely — no forwarding to keep in sync. Skew behavior is unchanged: an unmarked or unparseable envelope reads as the old Relay-only semantics. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01ExUfAkYbq8UC9pQCiLy8TQ * add enable-webrtc option; gate test_ipv6 under forced relay OPTION_ENABLE_WEBRTC (hbb_common 48c2d4d) follows the udp/ipv6 punch options end to end: default on against the public server, off against private ones, same settings UI placement on desktop and mobile, and the same bool2option local-option handling. Gates: - controller: should_create_webrtc_offerer checks it first — no pc, no STUN/TURN gathering, no offer in the request; - controlled: unlike the udp/ipv6 legs, which deliberately follow the request, answering builds a pc that gathers ICE from this host, so the answerer honors this machine's own switch too. Translations for "Enable WebRTC P2P connection" added to all 50 lang files next to the IPv6 entry (IPv6 and WebRTC are invariant terms in the same grammatical slot in every one of them). Also stop probing v6 reachability (test_ipv6) under any forced relay: the v6 punch socket is never bound there, so the probe was wasted work on every ws/proxy/relay connection.

Four now do, each through real 127.0.0.1 UDP sockets and the BytesCodec framing sessions use: - handshake + bidirectional framed roundtrip + graceful close: the peer observes end-of-stream instead of hanging (guard outlives the framed stream so the FIN goes out); - a writer that queues 50 frames and closes immediately loses none of them - the client-side pin for the close-tail-drain semantics; - socket errors after the peer vanishes are treated as loss: writes keep succeeding, nothing tears down (ICMP is advisory on connected UDP); - the connect deadline holds when nothing answers. Mutation-checked: dropping inbound forwarding in kcp_io reddens exactly the three tests that need the pump, and the timeout test alone stays green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01ExUfAkYbq8UC9pQCiLy8TQ * ipc/auth: replace the local throttle with the shared throttled_log! auth.rs predated hbb_common's LogThrottle and grew its own equivalent: same shape (last_log_at + suppressed), same 5s interval, plus a helper and three OnceLock<Mutex<..>> statics. It also counted the other way - excluding the event being reported - so each of the three sites carried two near-identical log::warn! arms to avoid printing "suppressed 0". The shared macro covers all of it: one static per call site declared by the expansion, and the multiplicity suffix appears only when there is one, which is what those duplicated arms were for. 102 lines out, 27 in. Behavior difference, deliberate: a burst now reads "(x47)" - the total including this line - instead of "(suppressed 46 similar events)". One number, no arithmetic, and one convention across the codebase. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01ExUfAkYbq8UC9pQCiLy8TQ * kcp: make the congestion-control profile opt-in, not the default The branch had flipped KCP to nc=0 (built-in congestion window) for every session. That is a transport-behavior change for all users made on reasoning alone, and the reasoning does not decide it: which profile wins depends on why packets are being lost. nc=1 - what RustDesk has always shipped - never shrinks the send window, so on a genuinely congested uplink it deepens the loss it is reacting to. But nc=0's backoff is blunt: a fast retransmit halves the window while an RTO sets cwnd = 1 outright (ikcp.c) and recovery slow-starts from one packet, so on a link with random loss and no congestion - Wi-Fi interference, a long-haul path - it reads loss as congestion and can stall an interactive stream for seconds. That failure mode is also the more visible one to a remote-desktop user. No benchmark settles this either: a loopback A/B has no bottleneck queue, hence no congestion to control, and would flatter nc=1 by construction. Deciding it needs a shaped link or field data. So keep the profile users already run and let the other one be asked for ("enable-kcp-congestion-control" = "Y"). Flipping the default later is a one-line change once there is evidence. kcp-sys keeps its own test covering the nc=0 path.

Raising the platform to 24 would have to drag minSdkVersion 22 with it and turn the link error into a load-time one on Android 5.1/6.0, so define the two symbols instead, using the RTM_GETLINK + RTM_GETADDR netlink dump bionic itself uses. The definition also shadows bionic's on API >= 24 rather than delegating to it, so the path that ships is the path every test device runs. Checked against synthesised netlink dumps on the host -- link/address parsing, prefix masks, point-to-point, ipv6 scope ids, malformed and truncated messages -- under UBSan and byte-exact guard malloc, with a deliberately unsigned remainder as the negative control. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix three ways ws + WebRTC could not work in practice Review of #15684 and hbb_common#579. Each of these left the code reading correct while the feature did not function. - The RelayResponse race classified P2P with `result.2 == "IPv6"`, but that site's futures are only ever the relay ("Relay"/"WebSocket") and the WebRTC branch's own "WebRTC" — so the predicate was constantly false. When the relay landed first the result was still right (the webrtc arm's `others_fut.is_none()` fallback), but when WebRTC connected FIRST it was parked as if it were a relay and the relay was committed on arrival, discarding a live direct connection. That is the LAN case: the better the network, the worse the outcome. Classify by what the label means, via is_direct_transport, and test both orderings — only the relay-first one was covered. - handle_peer_info wrote "force-always-relay=Y" into the peer's saved config whenever force_relay was set, which now includes the WebSocket transport. One ws session therefore turned the peer into a permanent relay-by-policy peer, and relay-by-policy means Relay-only ICE, so WebRTC could never go direct to it again — the flagship path worked exactly once. Persist policy_relay, which is the user's choice; the transport is a property of this client, not of the peer. - The answerer gated on this machine's enable-webrtc option, but that is LocalConfig: the UI process writes it and never syncs it over IPC, while handle_punch_hole runs in the server process, which on Windows resolves LocalConfig under a different profile and reads the private-server default of "N". The gate refused to answer in exactly the self-hosted deployments the transport exists for. Drop it: the answerer follows the request, like the udp/ipv6 legs, and the option still gates the feature where it can — an offer only exists because some controller had it enabled.

Client's own spawn_close_webrtc went with it: the runtime-teardown guard it existed for now lives in close_detached, so both Drop paths share one implementation. - webrtc_relayed() returns None when no candidate pair is selected or the pc closed under a concurrent teardown, and both call sites read that as "not relayed", i.e. direct. A TURN-relayed session could therefore be shown to the user as peer-to-peer. Claiming a direct path needs evidence of one, so an unknown answer now counts as relayed.

Orphan rules allow it because the RHS is its own type, and trait impls are visible across the whole dependency graph without a use, so std::time::Duration now has two Div candidates. `yuv_count as _` casts to a plain inference variable, which both candidates fit, so it stops resolving: error[E0282]: type annotations needed --> libs/scrap/examples/benchmark.rs:146:33 Only two of the four sites are reported - rustc emits one E0282 per function body - so all four are annotated. The already-explicit `as u32` at the hwcodec site and `start.elapsed() / cnt` are unaffected, the latter because an integer literal's variable can only unify with an integral type and rules the time impl out on its own. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * webrtc: judge the race by the resolved path, not the label; bound the ICE queue Third review round. Two of these are regressions from the previous one. - The RelayResponse race predicate was `is_direct_transport(result.2)`, which answers true for the label "WebRTC" - but WebRTC is only a direct path when ICE nominated a non-TURN pair. A TURN-relayed WebRTC result therefore committed instantly and cancelled the IPv6 attempt racing beside it, which is the same inversion the previous fix removed in the other direction. (That fix was also argued from a wrong premise: the site does carry an IPv6 future, pushed ~50 lines earlier than the relay one.) Each future now resolves whether its path is direct and the predicate reads that bool, matching the outer race, and the downstream recomputation goes away. - policy_relay still folded in Config::is_proxy(), and that is what gets persisted into the peer's config as force-always-relay - so one session through a proxy pinned the peer to relay forever and disabled WebRTC for it, exactly the latch the previous round fixed for WebSocket. Split out peer_relay: the saved option or an explicit request for THIS peer, and the only part written back. - The controlled side buffered remote ICE candidates in an unbounded channel while the controller caps the same buffer at 64, and draining one costs a JSON parse plus the ICE agent's lock. Whoever can reach a session's route could grow it without limit inside the long-lived service process. Bounded, with the overflow logged through the existing throttle. - That route was also removed by key alone when an answerer finished, so a punch retry that built a fresh answerer under the same fingerprint had its live sender deleted by the previous one's cleanup - after which it received no candidates at all. Evict only our own sender, the way the session cache already guards the analogous case.

A relay is now committed only when nothing direct can still arrive (or the window expires); a parked relay is also preferred over composing an error when both sides fail. Three regression tests, mutation-checked. - connect()'s plain select_ok let a TURN-relayed WebRTC win as "first success", dropping still-racing UDP/IPv6 direct attempts and reporting the relayed pair as direct. It now runs through the same prefer-P2P race with each attempt carrying whether its path is direct, and the WebRTC future resolves is_relayed() so a TURN win is held behind direct attempts, not committed as one. - The RelayResponse path kept direct == true when a WebRTC win's DTLS handshake failed and it fell back to relay, so the relay was reported P2P. Clear the flag with the transport switch. - Trim the OffererGuard doc to the three-line max; move the new enable-webrtc localization key to the end of every lang list; the KCP option constant moved to hbb_common config::keys (0f663aa).

The session end closed the pc by spawning onto io_loop's own `#[tokio::main(flavor = "current_thread")]` runtime, which is dropped the moment io_loop returns, and nothing after that call yields: the task was never polled even once, so no DTLS close_notify ever left. Every attempt to fix that on the caller's side failed the same way, because the mismatch was never about where the close ran: a pc's UDP sockets register with the reactor, and its ICE/DTLS/SCTP pumps spawn on the runtime, that is current while it is built — so a pc created by a session outlives the only runtime that can drive its I/O, and a close driven anywhere else completes without reaching the wire. The bump homes them where they can outlive any caller: WebRTCStream builds on a process-lifetime runtime and every detached close runs there as its own never-cancelled task. io_loop keeps its plain close_webrtc() calls and only documents why nothing here may spawn or await the teardown on the dying session runtime.

A transparent TCP proxy breaks that assumption: a TUN-mode VPN on the host, or a redirect-mode proxy on the LAN gateway serving every device behind it, completes the handshake locally in ~3ms while the real UDP round trip is hundreds of ms. Log-confirmed against 5.161.65.208: ping 341ms, TCP connect 3.7ms, connect to a dead port there "succeeds" just as fast. The window collapsed to ~1.5ms, udp_port stayed 0 on every attempt, and UDP punch was never even requested — although UDP itself passes such gateways untouched. So use the TCP clock only when it is believable: below a plausible WAN round trip it says nothing about the UDP path, and a flat ceiling applies instead. The loop still exits the moment the port arrives, so a genuinely nearby server pays nothing and only a UDP-dead network waits out the ceiling — on the udp-carrying round alone, while the parallel pure-TCP round is unaffected.

Add "Enable TCP hole punching" above the UDP toggle on both desktop and mobile, default on — including on self-hosted servers, since unlike the other three (whose default-off there guards against an hbbs that cannot forward their fields) TCP punching has always been supported by every server. Turning all four off would leave no way to punch at all, so TCP runs regardless in that case. That backstop keys off the switches alone: a transport that is enabled but fails to materialize — no public v6 address, no NAT port, a failed offerer — is already covered by the relay fallback for a round that ends up with no usable direct transport. With the TCP punch off, the fallback request is skipped too: it exists only to carry that punch, and would otherwise reach connect() with nothing to try and merely open a second relay. Known cost, unchanged behavior for the peer: the request carries no field for this choice, so a peer that receives one with no udp_port and no offer still punches a TCP hole and listens for a connection the controller will not make. Representing the transport choice on the wire needs a proto field and the server forwarding it.

A round carries several at once — a NAT port and a v6 address and an offer — and since the TCP punch became a switch it can carry none, so one name had to misreport both: the logs of the round that broke WebRTC read "#1 UDP punch attempt" while the request also carried the v6 address and the offer that was actually failing, and a round with nothing to punch with was labelled "WebRTC". List them instead — "UDP+IPv6+WebRTC" — and call the empty round "Relay", which is what it can still end as and what `typ` prints for it. The offer is moved into the request rather than cloned into it; that was its last use.

Each fails to bind with WSAEADDRNOTAVAIL, so ICE gathers no IPv6 host candidate at all on Windows - where a globally routable address is the one NAT-free path a CGNAT'd peer has. Never reported upstream; the unix twin of the same bug was fixed in webrtc-rs#475 (2023). Fork: rustdesk-org/webrtc, branch rustdesk-patches, tag webrtc-util-0.11.0-win-ipv6.

WebRTC does not: one label covers both families, and it is the one path whose real remote address can differ from the rendezvous-observed one the session is identified by. Refine it at the hand-off to the UI rather than at the source: five sites in client.rs compare `typ == "WebRTC"`, so widening the label there would silently move control flow.

It now reads `WebRTCStream::stun_servers()`, so an operator who points OPTION_ICE_SERVERS at their own server gets it on both paths instead of one. `test_bind_ipv6` sends nothing - `connect` only makes the kernel pick a route and a source address - so the whole cost is DNS. It races the lookups rather than betting this host's IPv6 support on whether the first entry happens to publish a AAAA where the user resolves from; google's does not, from a Chinese resolver, and it was the entry being bet on. `stun_ipv4_test`, `STUNS_V4` and `test_nat_ipv4` have had no callers since the punch stopped taking its port from a second socket, and go. `get_kcp_cc_enabled` reads the renamed option through `option2bool`, like every other one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019UzcMTdYTEv2QbMHcTSUy3 * webrtc: take dcsctp's retransmission timings and IPv6-safe MTU webrtc-sctp ships RFC 4960's RTO.Initial/RTO.Min (3000/1000), TCP's values for arbitrary public paths. On this workload they set the recovery time outright: a request/response exchange keeps one chunk in flight, so no later SACK ever raises miss_indicator to the 3 that arms fast retransmit, and the T3 floor is the only way back. A single loss during a handshake or a first keyframe therefore costs whole seconds. The fork now carries dcsctp's numbers instead - the SCTP implementation Google wrote to replace usrsctp for Chrome's WebRTC data channels, the same realtime workload: rto_initial 500, rto_min 400, a 220ms floor under the RTT variance, and mtu 1191. INITIAL_MTU 1228 plus DTLS/UDP/IPv6 overhead is 1313, past the 1280 minimum, so every full-size chunk fragmented on an IPv6 path. Both patch entries move to the new branch, which also carries the Windows IPv6 byte-swap fix, so one rev matches the whole webrtc 0.13 stack. * udp: make the punch prove itself, and keep the listener answering punch_udp sent a zero-length datagram and called the hole open on whatever arrived next. The rendezvous NAT test's own leftover replies satisfy that immediately - connect() does not flush the receive queue - so the retry loop never ran and success meant nothing. The dead socket then cost KCP its full timeout to rediscover, which is how a failed punch came to take 18 seconds. Probes now carry a magic and a 64-bit transaction id, and both ends answer each other's probes, so returning is a fact: a reply echoing our own id is the one thing that proves the pair carries traffic both ways. With failure now distinguishable from 'not yet', the window drops from 20s to 3s. Two asymmetries fall out of that: Only the connector stops on its own acknowledgement, because only it has something to send next. An acknowledgement proves our probe came back, not that the peer's probe was answered - and after punch_udp returns nothing answers probes any more, since KCP's io loop drops anything shorter than its header. A listener that stopped there would go mute while a peer whose own probe or answer was lost - the normal state of a hole still opening - kept probing an endpoint that works, until it timed out. So the listener stops on the peer's first real packet instead, and hands that packet to KcpStream::accept as its init_packet: its arrival proves the pair as well as an acknowledgement would, and KCP never retransmits its SYN. * webrtc: correct the RTT variance floor to dcsctp's scaling The earlier commit took dcsctp's min_rtt_variance = 220 as a raw floor under rttvar. dcsctp divides the option by kHeuristicVarianceAdjustment = 8.0 first, a historical accident it kept because downstream users had measured good values with it, so the intended floor is 27.5ms of variance contributing 110ms to RTO. Flooring at 220 contributed 880ms instead, which on a 50ms path left RTO within 7% of the 1000ms default this change exists to escape. The fork also now records why T1/T2 share T3's RTO manager here, unlike dcsctp's separate control timers: RTO_INITIAL is the T3 value for the first DATA chunk, since no RTT sample exists before the first SACK. * webrtc: skip the controller's ICE re-send instead of queueing it twice The controller sends every candidate twice, because the server's hop to a peer registered over UDP can lose one. The ICE agent that dedups repeats sits downstream of the answerer's queue, so the answerer paid for both copies: a slot, a JSON parse, and the ICE agent's lock, once per repeat. Remember a digest of what was queued and skip the repeat. Recorded only once queued, so a candidate a full queue refused stays repairable by the re-send. The queue's depth is unchanged. A real peer gathers well under it - four STUN servers, link-local IPv6 filtered, one component - and the drain empties it as candidates trickle in, so what this removes is the redundant work, not an overflow. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019aokqJuhjvB3kijXtAg5Ns * tcp: repeat the punch across the controller's dial window The single punch leaves before hbbs has told the controller where to dial, so it is never in flight at the same time as the controller's SYN: it opens our NAT, meets nothing, and a gateway that answers it with RST takes the mapping down with it, leaving the listener waiting on a hole that no longer exists. Punch again while the controller may still be dialing, and race those punches against the accept. That is two ways in where there was one: the mapping is rebuilt if a RST took it, and once the controller sits in SYN_SENT one of the punches meets its SYN and completes as a simultaneous open - which a punch sent before the controller had been told anything never could. The crossing reaches the punch rather than the listener because the two sockets share the address but only the punch matches the four-tuple, which the tests now pin down. There is no instant to aim at, and no window either. `Client::connect` sizes the controller's dial only after our PunchHoleSent, from its own rendezvous time and the direct failures it has recorded for us: CONNECT_TIMEOUT between two known-asymmetric NATs that never failed, punch_time_used times three or six otherwise, floored at a second - so a peer that failed once dials for a second or two from then on, and none of that reaches this side. The repeats therefore cover our own ceiling instead, CONNECT_TIMEOUT, which is exactly as long as the accept has always been willing to take a connection through the hole, and back off across it: dense at the start, where every window begins and the short ones end, sparse afterwards, which is `punch_udp`'s shape for the same reason. A window past that ceiling was lost before this change too, and mostly to the controller's own kernel - Windows gives a SYN up at 21s, Linux's next re-send after 15s is at 31s; a window short of it costs a few SYNs to a port already closed. No punch is cut on a per-attempt timeout; one in flight is bounded only by the shared deadline plus PUNCH_GRACE. A punch is cancel-safe only while it is still in SYN_SENT; once the controller's SYN has crossed it the socket is half way through a handshake, and cutting it there cuts the connection the controller is opening - whose `connect` has already returned, so that attempt fails outright, there being no relay fallback after a failed TCP handshake. A timer cannot tell the two states apart, and none is needed: a gateway that answers with RST fails the connect at once and the loop punches again, while one that drops the SYN in silence leaves the socket in SYN_SENT, holding the mapping open while the kernel re-sends, which any SYN of the controller's then crosses - a second punch has nothing to add. The deadline decides whether another punch starts; one in flight runs a grace past it, enough for a crossing begun just before it to complete. The last sleep is cut at the deadline rather than run out past it, so the window ends on a punch given that grace and not on a gap of up to the backoff ceiling: the controller's window opened after ours, on the PunchHoleSent hbbs relayed, so one as long as ours is still open through our tail. Only the accept races the punch, never `accept_connection`: that one does not return until the session it goes on to run has ended, so racing it would tear a live session down. Whichever arrives first is the one connection the request produces. `meta` carries the control permissions hbbs granted for this one controller, so serving the loser as well would hand them to a second peer - and nothing about a connection tells the two apart before `create_tcp_connection` has spoken to it, least of all its address: a carrier NAT shares one between subscribers, and a NAT that pools its external addresses may dial us from a different one than hbbs saw the controller through. So the address is not checked, as `accept_connection` never checked it; the handshake says who arrived, and what holds the invariant is that there is no second serve. Those permissions are a ceiling and not a grant either way: `Connection` gates every message on `authorized`, and latches the login scope of the first request it accepts, so a peer that reached the hole still arrives with nothing. The accept loops rather than taking a single connection, so that a transient accept error does not spend the window the controller still has to arrive in. libp2p's DCUtR reaches the same place by having both peers dial at one instant agreed over the relay. Nothing we send reaches the controller directly, so we cover its dial window rather than name an instant inside it.

Where the loss is random rather than congestion - a lossy long-haul link - the rate settles at the Mathis ceiling MSS/(RTT*sqrt(p)) however idle the link is: about 1.3 Mbps at 70ms RTT and 1% loss, 0.6 Mbps at 5%, while 1080p wants 2-5 Mbps. KCP's turbo profile (nc=1) has no congestion window at all. The fork now carries a switch that bypasses the two places gating sends on cwnd, and hbb_common turns it on for every peer connection unless `allow-webrtc-congestion-control` is set - the same opt-in KCP has in `allow-kcp-congestion-control`, for the reason at `get_kcp_cc_enabled`. Sender-side only; a browser or an older build on the other end interoperates. Measured over a simulated link (35ms one-way, random loss both ways, 12 KB frames at 30fps, 300 frames): at 1% loss the window stretches 9.9s of video to 20.7s with a mean latency of 5.5s; without it the stream stays realtime at a mean of 113ms. At 3%: 47s and 15s against 10.2s and 290ms.

Also fixes the delayed SACK timer never re-arming, the switch applying to established associations, T3-rtx resending one chunk when the peer's window is full, and bounds new data to 1 MiB / 1024 chunks in flight like KCP's snd_wnd.

The peer sets that rate, and an old-build peer's empty datagrams match no arm and loop without even the recv-error pause, so MAX_TIME went unchecked and the retransmit was starved with it. `udp_nat_connect` awaits the punch ahead of the KCP timeout and nothing above it bounds the phase, so the punch held the direct race open and the relay fallback out of reach for as long as the peer kept sending. Absolute instants for both clocks. The new test floods empty datagrams for four times the deadline: the punch now ends at 3s where it ran the full 12s. Also note at the symmetric-NAT branch that WebRTC not following the legacy relay decision there is deliberate, so it is not later "fixed" into agreement.

A chunk is fast retransmitted at most five times, KCP's IKCP_FASTACK_LIMIT. A frame's chunks go out within microseconds of each other, so on a path that jitters the send-order rule resent every chunk that landed behind three of its siblings: 2.7x the payload on the wire at 10ms of jitter, and on a link without the room for that, a queue that fed on itself. A reordering window, RACK's, makes evidence count only from what was sent a quarter of an srtt after the chunk once the path is seen to reorder, widening on the duplicate TSNs the receiver reports. 5 Mbps, 1% loss, 20ms jitter: 600 of 600 frames at a 98ms mean where 290 arrived at 6.2s. A chunk lost at the tail of a burst has only T3-rtx, which ran from floors sized for a 200ms delayed ack and restarted only on the tail's predecessor's ack: 600ms and more. Every DATA chunk now carries the I bit, the floors are KCP's shape, and a fast retransmission restarts the timer. One 200-byte message per frame at 5% loss: 9 of 600 later than 200ms, from 42. Random loss without jitter is unchanged at every rate and frame size.

Sending without a congestion window, a fast retransmission of any chunk restarted T3-rtx, so a chunk past the fast retransmission cap - left to that timer - never reached it while later chunks kept being resent, which a lossy stream does every couple of frames. The timer is the earliest in-flight chunk's, and only its resend restarts it now. Nothing else changes; the benchmark is unchanged.

The restart for the earliest chunk's fast retransmission reached only the Established branch of the write loop; the shutdown states still carry data in flight and recover it the same way, so a closing association could still resend everything on a loss its fast retransmit had already recovered. Both branches share one helper now.

palmoni5	f28ac38ccf	feat: optionally sync clipboard between connected sessions (#15934) ... * feat(clipboard): optionally sync clipboard between connected sessions Clipboard content received from a remote session is written to the local clipboard with an owner marker, so the client clipboard loop deliberately skips re-broadcasting it to avoid echo loops. As a result, text copied in one remote window could not be pasted in another connected remote window. Add an opt-in local option (allow-sync-clipboard-between-sessions) that relays Clipboard/MultiClipboards messages received from one session to all other connected sessions, excluding the source session. Per-session clipboard permissions and view-only mode are still respected via the existing send path, and the owner marker on the receiving peers prevents any echo back. Desktop (flutter) only; file clipboard is not affected. * fix(lang): propagate sync-clipboard-between-sessions-tip to all locale files Add the new key to template.rs and every locale file per the localization convention, move the en.rs entry to the end of the list, and drop comments that only restated the names next to them. * fix(lang): add the 'Sync clipboard between sessions' label to the localization catalog The checkbox label goes through translate(), so add it to template.rs and every locale file so non-English locales can translate it. en.rs is skipped since the English display text is identical to the key. * fix(clipboard): check the source session's full clipboard permission before relaying The relay was gated only by the incoming clipboard_allowed check (!disable_clipboard && !view_only). Gate it with is_text_clipboard_required() instead, which additionally respects the source session's server_clipboard_enabled and server_keyboard_enabled state, matching the predicate already applied to destination sessions. A message arriving after the source permission was revoked (or from a non-conforming peer) is no longer propagated to other sessions. The existing local update_clipboard behavior is unchanged. * fix(lang): translate the new clipboard sync entries in all locale files Fill the 'Sync clipboard between sessions' label and its tooltip in every locale file instead of leaving them blank, following each file's existing terminology. template.rs keeps the empty master entries.	2026-09-01 10:47:26 +08:00
RustDesk	7aa98d43cf	Refact/plugin removal leftovers (#15864) ... * fix(flutter): dispose the settings PageController and order dispose() correctly `dispose()` began with `super.dispose()`, so the mixin chain marked the State defunct before the WidgetsBindingObserver registration and the periodic timer were released. The `PageController` was never disposed at all: `Get.delete` only runs `onDelete()` for a `GetLifeCycleBase`, and a plain `ChangeNotifier` is not one, so every open/close of the Settings tab leaked one controller with its listener still attached. Also guard `switch2page` on the `Rx<SettingsTabKey>` registration it actually reads rather than only the `PageController` — now that both are really deleted, a partial teardown would throw into the catch and silently open the wrong tab — and re-check `mounted` after the await in the `_videoConnTimer` tick, which `Timer::cancel` cannot stop once the body has started. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refact: finish the plugin-framework removal sweep #15854 removed the feature but stopped short of its leftovers: - `Uninstall`, `Enable`, `Disable`, `Options` and `Please install plugins` were consumed only by the deleted `flutter/lib/plugin/**`; drop them from template.rs and the 50 locale files (250 dead entries). `Update` and `Install` stay, still used by desktop_home_page.dart. - The server no longer sends `PrvOnFailedPlugin`, and the client no longer offers to install plugins when privacy mode fails to turn on. - Drop the MSI `F_Client_Plugins` / `F_Server_Plugins` localization strings; no `.wxs` references them. - `_DisplayMenu`'s constructor became a pure pass-through once `pluginItem` was removed, and the cfg inside `handle_input` repeats the one on the function itself. - Normalize `src/lang/sl.rs` to 0644, the only executable file under src/.
