enricobuehler	b168790e0a	refactor(host/W6.2): extract the shared frame/format vocabulary into the pf-frame leaf crate ... The captured-frame types both capture (producer) and encode (consumer) speak — PixelFormat, OutputFormat, CursorOverlay, CapturedFrame, FramePayload, DmabufFrame, drm_fourcc — move into crates/pf-frame, alongside the small pure helpers that ride the same seam: hdr (HDR static metadata / in-band SEI), metronome (the metronomic-stall detector), thread_qos (per-thread scheduling QoS), session_tuning (Windows process tuning), and the Windows DXGI capture IDENTITY (WinCaptureTarget, D3d11Frame, pack_luid, make_device + the GPU scheduling-priority hardening it applies) (plan §W6). This is the crate that breaks the capture<->encode cycle: FramePayload's GPU variants own their backends from BELOW (Cuda -> pf_zerocopy::DeviceBuffer, D3d11 -> dxgi::D3d11Frame), so encode can speak the vocabulary without a path to capture, and vice versa. The Windows DXGI identity moving here lets capture, encode, and pf-vdisplay share ONE WinCaptureTarget/device factory instead of the old capture<->encode<->vdisplay reach-in. The host keeps thin facades: capture.rs re-exports the vocabulary (crate::capture::{PixelFormat,…} unchanged); capture/windows/dxgi.rs keeps the win32u GPU-preference hook + HDR/video-engine converters + self-test and re-exports the identity; native.rs re-exports boost_thread_priority from pf_frame. crate::hdr/metronome/session_tuning callers rewired to pf_frame::*. metronome's Metronome::new gained a Default impl (new_without_default fires once the type is public across the crate boundary). Verified: Linux clippy -D warnings (pf-frame --all-targets + host nvenc,vulkan-encode,pyrowave --all-targets) + 9/9 pf-frame tests; Windows clippy nvenc,amf-qsv --all-targets Finished exit 0.

enricobuehler	3495d189e1	refactor(host/W6.1): extract the config() global into the pf-host-config leaf crate ... Third de-coupling for the host crate carve (plan §W6.1 leaf). HostConfig + the config() OnceLock (config.rs, pure std, zero deps) move to a new pf-host-config leaf so every subsystem crate (pf-encode/pf-capture/pf-vdisplay/pf-gpu) can read process config WITHOUT depending on the orchestrator. 34 crate::config::config() call sites across 19 files repoint to pf_host_config::config(). thread_qos stays in the host for now (it calls session_tuning::on_hot_thread — its own leaf-ification rides the encode carve). Granular-crate decision (supersedes the plan's single pf-media): split capture/encode/ vdisplay into separate crates rather than one broad crate — the capture↔encode cycle is broken by a shared frame-types leaf, and vdisplay→encode (can_open_another_session) is a legal one-way edge since encode never references vdisplay. Verified: Linux (home-worker-5) clippy -p pf-host-config -p punktfunk-host --all-targets -D warnings; Windows (192.168.1.158) clippy --features nvenc,amf-qsv --all-targets green.

enricobuehler	c42ce88921	refactor(host/W6.1): extract secret/config-dir helpers into the pf-paths leaf crate ... Second de-coupling for the host crate carve (plan §W6.1 leaf). config_dir / create_private_dir / write_secret_file (+ the Windows DACL helpers) were pub(crate) in the gamestream junk drawer, yet consumed by vdisplay, stats, gpu, library, mgmt_token, native_pairing and the Windows service — many of which become pf-media / pf-vdisplay, for which crate::gamestream would be an illegal upward edge. New leaf crate pf-paths (pure std + tracing) owns them; ~40 call sites across 14 files repoint to pf_paths::. gamestream keeps only its own concerns. Verified: Linux (home-worker-5) clippy -p pf-paths -p punktfunk-host --all-targets -D warnings + tests (347 pass, incl. secrets_are_written_owner_only); Windows (192.168.1.158) clippy --features nvenc,amf-qsv --all-targets green.

enricobuehler	2e3208f75e	refactor(host/W6.0): drop gamestream BTN_* aliases; injectors read core directly ... Finishes the gamepad-vocabulary un-coupling (plan §W6.0): the Linux uinput button map now names BTN_* straight from punktfunk_core::input::gamepad instead of the crate::gamestream re-export aliases, so pf-inject will carry no edge into the gamestream junk drawer for gamepad constants. Removes the now-dead alias block; the wire-bit pinning test (gamepad_wire_bits_are_pinned) pins core directly (equally strong — core is the single source). gamestream keeps only the decode path, which imports the types from core. Verified: Linux (home-worker-5) clippy --all-targets -D warnings + gamepad tests green; Windows (192.168.1.158) clippy -p punktfunk-host --features nvenc,amf-qsv --all-targets green.

enricobuehler	47587827ec	refactor(host/W6.0): hoist GamepadEvent/GamepadFrame to punktfunk_core::input ... First de-coupling for the host crate carve (plan §W6.0 / §2.4): the GameStream (Moonlight-plane) decoded controller types were defined in gamestream/gamepad.rs — the "junk drawer" — yet consumed 18× by the platform-neutral input injectors AND by the Moonlight decode path. Once inject becomes pf-inject, reaching them via crate::gamestream would be an illegal upward edge. Move the two types to core::input (below both planes; inject already depends on core) and repoint every consumer. Also consolidate the duplicated MAX_PADS onto the existing core::input::MAX_PADS. The gamestream BTN_* const aliases stay for now (separate follow-up); decode()/rumble/tests remain in the Moonlight plane, now importing the types from core. Verified: Linux (home-worker-5) clippy -p punktfunk-core -p punktfunk-host --all-targets -D warnings + gamepad tests green; Windows (192.168.1.158) clippy -p punktfunk-host --features nvenc,amf-qsv --all-targets green (the inject/windows/* consumers compile).

enricobuehler	aaa3dcec32	refactor(host/W4): make the capture→encode edge one-way (OutputFormat back-ref) ... The capture.rs facade no longer re-derives the encode backend. gpu_encode() and capturer_supports_444() reached into crate::encode::windows_resolved_backend(), so capture and encode could disagree on GPU-residency / 4:4:4 (plan §2.4). Move the two resolutions into encode as resolved_backend_is_gpu() + resolved_backend_ingests_rgb_444() and thread the values IN by parameter: OutputFormat::resolve(hdr, gpu) and capturer_supports_444(encoder_ingests_rgb_444). Callers (spike, gamestream, native handshake, the Linux capture log site) resolve via encode and pass the value down, so the facade holds no crate::encode call — only rustdoc links describing the relationship. Completes task #8 of W4. Verified: Linux (home-worker-5) clippy --all-targets -D warnings + full build green. Windows (.173) verify owed — box was offline this session.

enricobuehler	63efe0ecd5	feat(host/hooks): per-app prep/undo commands (M2b — Sunshine prep-cmd parity) ... `prep: [{"do": …, "undo": …}]` arrays on GameStream apps.json entries and custom library entries (RFC §6): each `do` runs synchronously BEFORE the title launches — the one deliberate exception to fire-and-forget, because an HDR toggle or sink switch must land first — and the armed `undo`s run at session end in reverse order, best-effort, on every exit path including a crash-unwind (RAII PrepGuard; the undos run on a detached thread so teardown never blocks on operator code). - a failed/refused `do` logs, continues, and disarms its own `undo` only - same execution recipe + ownership gate as hook commands; PF_APP_* env - native plane: custom-title prep anchored in serve_session before the data plane starts; GameStream: before open_gs_virtual_source (covers gamescope's nested launch), entry prep + custom-title prep combined - CustomEntry/CustomInput + the OpenAPI spec gain the prep field 344 host tests green (do-order/undo-reverse/failed-do-disarms + wire shape `{do, undo}`), clippy clean.

enricobuehler	46c0e0e483	feat(host/hooks): operator hooks — exec + webhooks on lifecycle events (M2a) ... hooks.json (RFC §6): commands and webhooks fired on host lifecycle events, managed over GET|PUT /api/v1/hooks (validated, applied immediately) and dispatched fire-and-forget by a bus-subscriber runner — hooks observe, never veto, and no operator code sits in any streaming path. - exec: detached sh -c with the event JSON on stdin + flat PF_EVENT_* env (the PF_STREAM_* vocabulary's sibling), per-hook timeout (default 30 s) with process-group kill, off-thread reap, per-hook debounce, bounded concurrency (8 in flight, excess dropped loudly). Windows runs hooks in the interactive user session (temp-file JSON argument; console-mode dev hosts get env + stdin like Unix). - webhook: POST the event JSON, TLS-verified, redirects never followed, no punktfunk credentials outbound; optional per-hook secret file yields X-Punktfunk-Signature: sha256=<hex HMAC> (fails closed if unreadable). - filters: exact-match client/fingerprint/plane/app + the same kind patterns as the SSE ?kinds= filter (shared crate::events::kind_matches). - hardening (RFC §9.1): hooks.json via the private-dir/secret-file helpers; a hook script path must be operator/root-owned and not group/world-writable or it is refused loudly (the sshd rule). - env mirrors PUNKTFUNK_ON_CONNECT_CMD / PUNKTFUNK_ON_DISCONNECT_CMD for the zero-config cases, beside PUNKTFUNK_RECOVER_SESSION_CMD. Live-verified on Linux: PUT config via API → library.changed fired a real script (env + stdin observed) and an HMAC webhook (receiver-verified signature); a chmod-777 script was refused. 342 host tests green (store/validation/filter/env-flatten/exec-timeout/ownership + routes), clippy clean.

enricobuehler	ecfa71212d	chore: consolidate all in-progress parallel-session WIP ... Wholesale commit of every uncommitted change across the tree, at the user's explicit request — host refactor-campaign W1 (native.rs facade + native/ dir, library/ + mgmt/ splits), Android, core. These streams were mid-flight and not individually built/tested together; this supersedes the per-session HOLD markers. Consolidating so everything lands on main in one pass.

enricobuehler	11045a0f70	chore: consolidate parallel-session WIP (HOLD — do not push) ... Local snapshot of intermingled in-flight work, committed to unblock the encode refactor (a clean ffmpeg_win.rs for the vbv-dedup follow-on). These hunks span the same files and can't be cleanly split here; the commit bundles three distinct workstreams that each belong in their own PR: - logging rework (~43 files: level re-tiering, structured fields, `?e`, hot-path flood latches) - conflicting-host detection (detect.rs + detect/{linux,windows}.rs + wiring in main.rs/mgmt.rs/Cargo.toml/docs/packaging) - standby-sink DWM-stall attribution (windows/display_events.rs + capture/ vdisplay wiring) NOT verified as a combination. NOT to be pushed until the refactor is done and these are re-verified and reorganized into their proper per-workstream PRs.

enricobuehler	6b9f261dff	style(host): rustfmt sweep for the console-sweep push ... b8da32e8 landed with two call sites and a log line rustfmt rewraps; CI's cargo fmt --all --check gate was failing on every run since.

enricobuehler	b8da32e8b6	fix(host): native sessions on the console + GPU-aware codecs + gamestream capability ... The web console Dashboard read AppState.{streaming,launch,stream}, which only the GameStream path writes, so a native punktfunk/1 session (the DEFAULT plane) showed "Idle / no session" while actively streaming — only the Stats page (shared recorder) reflected it. Add a plane-neutral per-session registry (session_status.rs) the native video loop publishes to; /status now merges both planes, reports active_sessions, and the Stop / Request-IDR buttons reach native sessions too (so surfacing them doesn't leave dead buttons). LocalSummary (tray) gets the same fix. Also on the management API: - /host codecs derive from Codec::host_wire_caps() instead of a hardcoded [H264,H265,AV1], so codecs the GPU can't encode no longer appear. - ApiCodec serializes HEVC as "hevc" (matching the wire/SDP/stats label) so the same codec reads identically across console pages. - HostInfo.gamestream reports whether the GameStream planes run (--gamestream), so the console can hide the Moonlight-only pairing UI on the native-only default host. - StatsStatus.elapsed_ms (host-monotonic) so the capture timer doesn't mix host/browser clocks.

enricobuehler	f4f6c5556f	perf(core): FEC encoder reuse — cached codecs + pooled parity, no per-block setup ... Phase 1.4 (throughput-beyond-1gbps.md): the send path built a fresh erasure codec and allocated fresh parity Vecs for every FEC block. New trait method ErasureCoder::encode_into generates parity into caller-pooled buffers; the packetizer keeps one parity pool that grows once to the session's high-water recovery count. - gf16: one cached reed_solomon_simd::ReedSolomonEncoder per coder, re-shaped per block via reset() (reuses its working space) — the old encode() convenience call paid engine CPU-feature detection, FFT planning, and work-buffer allocation per block. - gf8: last-used (k, m) Cauchy codec cached, so the generator-matrix build drops out of steady-state frames; parity buffers shaped without re-zeroing (encode_sep's first-input pass overwrites every row). The GameStream VideoPacketizer now owns a persistent coder so the cache survives frames. - encode() delegates to encode_into — one code path, and the nanors byte-exact parity vector keeps pinning Moonlight wire compatibility. Validated: 145 core + 308 host tests + clippy -D warnings on .21, loss-harness recovery curve identical, pipeline bench +0.6-2.4% thrpt (all configs, p<0.05; the loopback bench is encoder-dominated so the alloc savings mostly land outside it).

enricobuehler	17457cf4ba	refactor(gamestream/host): source gamepad BTN_* from punktfunk_core + pin the wire bits (G13/G15) ... `gamestream/gamepad.rs` hand-declared its own copy of the GameStream buttonFlags/buttonFlags2 layout, which had drifted from the single source of truth in `punktfunk_core::input::gamepad`: the click bits were named `BTN_LS_CLK`/`BTN_RS_CLK` (vs core's `…_CLICK`). The two layouts are bit-identical — GameStream/Limelight and the punktfunk/1 native wire are one contract — so define the gamestream names as `pub const` aliases of the core constants. Values now come solely from core (can't drift); kept as `pub const` (not a `pub use` re-export) because on Windows the only consumer — the Linux uinput button map — is cfg'd out, where an unused re-export lints as an error but an unused pub const does not. Rename the two injector call-sites (`inject/linux/gamepad.rs`) to the canonical `BTN_LS_CLICK`/`BTN_RS_CLICK`. G15 host half: replace the 3-bit gamestream-vs-core spot-check with an exhaustive golden-value test (`gamepad_wire_bits_are_pinned`) that freezes every button bit + axis id to its exact wire value, so renumbering a bit in core — which would silently break every shipped client — fails a test first. The host counterpart to the client-side C-ABI cross-checks. Verified on Linux .21: clippy -D warnings clean, pin test + gamepad suite green. (Windows verified together with the rest of Phase 3.)

enricobuehler	fdda7144ed	fix(encode): harden loss-recovery correctness across host encoders (F1–F7) ... Phases 1–4 of design/encoder-recovery-hardening.md — make the shipped RFI/ freeze-until-reanchor recovery honest and rebuild-safe across every backend. F1 — frame-index domain desync: the encode loop now owns a session-lifetime `au_seq`; `Encoder::submit_indexed(au_seq + inflight)` pins NVENC inputTimeStamp and AMF LTR slots to the WIRE frame index, so `invalidate_ref_frames` compares client frame numbers in the same domain and survives adaptive-bitrate rebuilds (an internal counter desynced on the first rebuild → RFI silently dead / an AMF force-ref onto a never-decoded frame). `FrameMsg.frame_index` → `Session::seal_frame_at`; GameStream gets the same via `VideoPacketizer:: packetize(.., Some(idx))`. F2 — Windows NVENC left the client frozen ~1s per loss: NVENC RFI was transparent (no anchor tag) while the session glue armed the 750ms IDR cooldown, so the freeze only lifted on the ~1s keyframe re-ask. NVENC now mirrors AMF — `pending_anchor` tags the first post-invalidate AU (the clean re-anchor P-frame) `recovery_anchor`, incl. the covering-range dedupe re-arm; the client lifts at ~RTT. F3 — speed-test probe filler burned video frame indexes: moved to its own index space (`Packetizer::alloc_probe_index` + `Session::submit_probe_frame`) with a second client reassembly window routed on FLAG_PROBE, gated on the new VIDEO_CAP_PROBE_SEQ Hello bit (mid-session probes declined for older clients). F4 — RFI range sanity cap: forward gaps wider than `packet::RFI_MAX_RANGE` (256) resync via keyframe instead of an out-of-range RFI, host- and client-side (client huge-gap → keyframe in `RfiRecovery::observe` + the pf-client-core pump). F5 — reset() parity: Windows NVENC (teardown + lazy re-init), Linux VAAPI (drop-inner), Linux NVENC (reopen from stored OpenArgs) now give the stall watchdog a heal lever instead of ending the session. F6 — sw.rs `pending: VecDeque` (was `Option`), killing the silent AU drop at capturer pipeline depth > 1. F7 — doc sweep on the RFI/anchor comments. Verified: punktfunk-core lib tests (macOS + Linux), full punktfunk-host suite on Linux (RTX 5070 Ti), Windows compile. Owed: the on-glass client matrix (F2 freeze A/B, AMF LTR spike across a bitrate rebuild). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-12 11:17:19 +02:00
enricobuehler	35d97ae6ac	feat(windows): parallel virtual displays — proto v3 ring binding, manager slot map, group topology (W0–W3) ... design/windows-parallel-virtual-displays.md (display-management Stage 7 / §6.6): N simultaneously-live pf-vdisplay monitors, one sealed ring each, every idd-push-security invariant preserved per-ring. - proto v3: SharedHeader._pad → target_id — the ring NAMES its monitor, host-stamped before the magic; the driver publisher refuses a cross-bound ring via the shared, unit-tested frame::check_attach (new DRV_STATUS_BIND_FAIL — the gamepad pad_index validation applied to frames, invariant #10); the host's wait_for_attach surfaces the refusal loudly and self-checks its own stamp. - manager: the one-monitor MgrState becomes a slot map keyed by the client's identity slot (0 = anonymous/GameStream); per-slot reconnect + dead-WUDFHost preempts, slot-scoped begin_idd_setup (a different identity is an admission question, never a preempt), ONE device-level watchdog pinger, per-slot /display/state + /display/release. - group topology: isolate_displays_ccd takes the managed target SET (a sibling slot is never deactivated); SavedConfig + the DDC/PnP axes move to the group record (first-in captures, last-out restores); desktop layout via CCD source origins from the pure layout::arrange (auto-row default, manual pins win), re-applied on create + reconfigure. - admission: the Windows separate→reject override now sits behind the PUNKTFUNK_WIN_SEPARATE=1 validation hatch (the wedge it guarded is structurally gone — a second identity gets its own monitor + ring; default flips in W5 after soak); max_displays and NVENC session-unit budgets decline an unaffordable display AT admission; kick_dwm_compose is process-globally throttled and per-display — cursor jump + 35 ms dwell (a sub-tick jump composes nothing; DWM reads dirties from current state at the next vsync tick). On-glass on the RTX box: V1/V2/V4/V5/V6/V9 green — two paired clients on two monitors streaming ~60 fps each with zero mismatches and zero bind failures, churn-hammer clean (no 0x80070490), per-ring mode-change recreate leaves the sibling untouched, typed budget rejection, fault-injected cross-bind refused loudly with the sibling undisturbed. V7: WUDFHost-kill shared fate is clean; in-process device recovery is a known follow-up (the retired-never-closed control handles block the adapter cycle — reset-pf-vdisplay.ps1 recovers). DWM composes two IDD monitors concurrently at 60 fps — the plan's load-bearing unknown, answered yes. Also carries the client-HDR EDID forwarding that shared this working tree (Hello::display_hdr → AddRequest luminance tail → the monitor's CTA-861.3 HDR block, PUNKTFUNK_CLIENT_PEAK_NITS hatch) and the Deck client fixes (40 ms rumble keep-alive with 1-LSB jitter, HDR self-diagnosing presenter warn, flatpak HDR env).

Clients derive Y'CbCr->RGB from the stream's SIGNALED matrix x range x depth via shared csc rows (Rust csc_rows + Swift CscRows) instead of hardcoded 709/2020 - a BT.601-signaled stream (a Linux host's RGB-input NVENC) no longer renders with a constant hue error. Host-side signaling made honest across NVENC/VAAPI/openh264/GameStream and the session plan's chroma/bit-depth. Decoded color-bar fixtures (601/709 x limited/full) pin the math in tests on both cores. Same presenter, tvOS HDR: tvOS has no Metal EDR API and a bare PQ colorspace tag composites UNTONE-MAPPED (the "overblown" Apple TV report), so HDR now splits on the display's live EDR headroom - PQ passthrough when the per-session AVDisplayManager mode switch landed (a real HDR10 output tone-maps itself), else an in-shader PQ->SDR tone-map (203-nit reference white, extended-Reinhard 1000-nit knee, 2020->709) into the proven SDR layer config.

enricobuehler	d1770c3476	refactor(host): shared send-pacing policy for the native and GameStream video planes ... Networking-audit deferred plan §5. Both planes spread a frame's wire packets across a time budget in chunked bursts; the schedule logic, PUNKTFUNK_VIDEO_DROP loss injection, and percentile helper were duplicated between punktfunk1::paced_submit and gamestream::stream::spawn_sender. Now one host-local send_pacing::pace_frame carries the policy; each plane keeps its exact historical parameterization and its own syscall layer (GSO Session vs sendmmsg over the RTP socket — policy shared, plumbing not): native burst_bytes = PUNKTFUNK_PACE_BURST_KB (microburst stage), fixed 16-packet chunks, budget = 0.9 × time-to-deadline gamestream no burst stage, bounded steps (≤ 12, chunk ≥ 16, the old pace_layout), fixed budget = 0.75 × frame interval Deterministic-schedule unit tests pin both parameterizations against verbatim transcriptions of the legacy math (burst split, chunk layout, step counts — including pace_layout's historical test anchors) and the sleep-target formula (GameStream's legacy per_step form agrees to ≤ steps/2 ns; the unified fraction form is used for both). Deliberate sub-observable normalizations, all on test-knob or ns-scale paths: PUNKTFUNK_VIDEO_DROP is now parsed once per process and clamped to 1..=90 on the GameStream plane too (was per-stream, unclamped), and the native sleep floor comparison is now >= (was >, differs only at exactly 500 µs). Validation: - 263 host tests green, incl. the end-to-end sender_delivers_batches (spawn_sender → pace_frame → sendmmsg, byte-identical delivery) - PUNKTFUNK_VIDEO_DROP FEC sweep at 5 % and 8 % injected wire loss: all 11 punktfunk1 integration tests (full host↔client roundtrips through send_loop → paced_submit) recover and pass - pending: one real Moonlight smoke session against this build (the legacy-plane timing gate) — recipe handed to the operator Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 16:26:41 +02:00

enricobuehler	9afcbcd307	feat(transport): Windows DSCP via qWAVE flows — PUNKTFUNK_DSCP now real on the wire there ... Networking-audit deferred plan §4 (the qos.rs follow-up). On Windows set_tos_v4 succeeds but the stack strips the mark without a qWAVE flow, so PUNKTFUNK_DSCP=1 was a silent wire no-op there. Now (Apollo/Sunshine's approach): QOSCreateHandle once per process; QOSAddSocketToFlow per connected media socket — video → QOSTrafficTypeAudioVideo, audio → QOSTrafficTypeVoice (QOS_NON_ADAPTIVE_FLOW) — then best-effort QOSSetFlow(QOSSetOutgoingDSCPValue, 40/48) to pin the exact CS5/CS6 the other platforms mark. The pin lands for elevated processes (the host runs as the SYSTEM service — exactly where the video egress is) or under the "allow non-admin DSCP" policy; otherwise the traffic-type default marking stands (still WMM-useful). Gating + contract unchanged: opt-in via dscp_enabled(), every step debug-logs and continues. set_media_qos now returns an RAII QosFlow guard (QOSRemoveSocketFromFlow on drop) that must outlive the socket's traffic: stored in UdpTransport (declared before the socket, so drop order removes the flow first) and held for the stream's scope by the GameStream video/audio senders — whose tagging moved after connect(), since qWAVE derives the flow's 5-tuple from the connected socket (behavior-neutral on Linux). Off-Windows the guard is inert and never constructed.

enricobuehler	cdbdc078d6	perf(core): ref-based FEC encode — packetize shards reference the frame in place ... Stage A of the zero-copy host packetize path (networking-audit deferred plan §1): ErasureCoder::encode now takes &[&[u8]], so Packetizer::packetize builds each block's data shards as slices straight into the frame buffer instead of allocating + copying a Vec per data shard. Only the frame's final (possibly partial) shard is staged in a reusable zero-padded scratch; blocks are consecutive shard ranges, so every other shard is a full payload-sized slice. - gf8: encode_sep() over the same Cauchy codec — parity byte-identical to nanors/Moonlight (nanors_exact_parity_vectors unchanged and green) - gf16: reed_solomon_simd::encode is already generic over AsRef<[u8]> - loss-harness sweep: recovery rates identical before/after - bench pipeline (end-to-end, host+client): gf8/64K -3.0%, gf16/64K -2.2%, gf16/1M -3.4%, gf8/1M -0.7% Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 15:16:07 +02:00
enricobuehler	5d9f1ccb6d	feat(host): --no-mdns/PUNKTFUNK_MDNS gate + punktfunk1-host --pairing-pin — docker-testing enablers ... mDNS advertisement (native _punktfunk._udp AND GameStream _nvstream) can now be disabled with --no-mdns on serve/punktfunk1-host or PUNKTFUNK_MDNS=0 (the PUNKTFUNK_ZEROCOPY off-grammar) — for multicast-dead environments (bridged Docker, CI netns) where the advert reaches nobody or fails outright and aborts the GameStream plane; clients dial a manually-added host instead (mDNS-blind host-add works since the 0.8.4 dial-first fix). Unit tests no longer advertise on the LAN (mdns: false). punktfunk1-host gains --pairing-pin <PIN> (the already-plumbed fixed-PIN test seam, now CLI-exposed; empty refused like --mgmt-token) so a CI harness runs a deterministic SPAKE2 ceremony instead of scraping the logged PIN. Verified live: --no-mdns + PUNKTFUNK_MDNS=0 skip the advert, --pairing-pin arms with the fixed PIN, and a punktfunk1-host --source synthetic + punktfunk-probe loopback run passes verification (60/60 frames, 0 mismatch).

enricobuehler	838a1239cf	feat(codec): make client codec selection real — GPU-aware native advertisement ... The clients' codec pickers sent a preference the host threw away: host_wire_caps() hardcoded HEVC for every GPU backend, so the native path never emitted H.264/AV1 regardless of what the user chose. Host: advertise what the backend actually encodes, mirroring the GameStream serverinfo logic — software openh264 emits H.264; probed backends (Linux VAAPI, Windows AMF/QSV) advertise their per-GPU CodecSupport via the new wire_mask(); NVENC keeps the Moonlight-validated H.264|HEVC|AV1 static superset; an empty probe falls back to the superset so auto clients still resolve HEVC. Gate 10-bit to HEVC (like the 4:4:4 gate) now that a client can steer the codec — Main10 is the only 10-bit encode path. Fix the web-console stats label hardcoded to "hevc" (new Codec::label(), shared with the GameStream register_session mapping). Android: replace the hardcoded H264|HEVC Hello advertisement with a videoCodecs param fed by VideoDecoders.decodableCodecBits() (AV1 bit only when a real hardware video/av01 decoder exists — the decode loop was already mime-driven); offer AV1 in the codec picker on capable devices. Decky: add the missing "Video codec" dropdown (auto/hevc/h264/av1) to the plugin settings, round-tripping the same codec key the flatpak client reads. Apple: unchanged by design (AnnexB.swift is NAL-only, AV1 is never advertised); refresh the stale "hosts don't emit AV1 on the native path yet" comments here and host-side.

enricobuehler	349d16382e	fix(stats): decode stage measures GPU completion; Alt+Enter fullscreen alias ... The Vulkan path's receive_frame returns at SUBMISSION (~0.1 ms) — the hardware decodes asynchronously, so the decode stat was truthful but measured the wrong boundary. The pump now ships the frame to the presenter FIRST, then waits the frame's timeline fence (vkWaitSemaphores resolved through the shared device's proc chain) and stamps received→decode-COMPLETE — true NVDEC time at zero pipeline cost, since the presenter's own GPU wait is what actually gates sampling. Software/ VAAPI keep their synchronous stamps. Also: Alt+Enter joins F11 as the fullscreen toggle (some keyboards' Fn layer sends a media key for plain F11 — observed on glass as 'F11 only works with shift'); the shell's shortcuts panel lists both.

enricobuehler	6f47abab8c	feat(host): native AMF SDK encoder for Windows AMD — drop libavcodec ... Direct-SDK AMF encoder (encode/windows/amf.rs), the AMD analogue of the direct-NVENC path, replacing the libavcodec *_amf dispatch. C-vtable FFI pinned to AMF headers v1.4.36, runtime-loaded from the driver's amfrt64.dll (no build feature, no new dependency) exactly as NVENC loads its DLL. - AVC/HEVC (SDR NV12 + 10-bit HDR P010) and AV1 (RDNA3+, probed); a bounded poll retires the libavcodec ~2-frame output hold; native in-place reset(). - Intra-refresh wave (PUNKTFUNK_INTRA_REFRESH), in-band HDR mastering/CLL metadata (*InHDRMetadata -> HEVC SEI / AV1 OBU), and a native codec probe feeding the GameStream advertisement (windows_backend_is_ffmpeg -> windows_backend_is_probed). - AMD dispatch / advertisement / 4:4:4 are native-only; the libavcodec AMF fallback and the PUNKTFUNK_AMF_FFMPEG hatch are removed. FFmpeg serves QSV only (its AMF path retained solely as the latency A/B comparator). - Overload back-pressure: submit bounds in-flight surfaces below the input ring, draining finished AUs (buffered for poll, FIFO-preserved) to free a slot and retry on AMF_INPUT_FULL instead of tearing the encoder down and forcing an IDR; this also closes a latent ring-overwrite corruption seen under load on-glass. Validated on the lab Ryzen iGPU (AMF runtime 1.4.37): HEVC/AVC across a native reset, HEVC Main10 mastering+CLL SEIs byte-verified, intra-refresh accepted, a backpressure burst FIFO-clean, and end-to-end via the macOS client. Measured §5.2 latency A/B: native encode_us p50 ~5 ms (0.31 frame periods) vs libavcodec ~17 ms (1.01). 4:4:4 stays unsupported (VCN hardware limit). Live-gated tests skip cleanly on non-AMD boxes.

enricobuehler	1992eb1c52	feat(host): game-mode integration + dedicated game sessions ... Implements design/gamemode-and-dedicated-sessions.md (Parts A1-A5 + B0-B2): reconciles the merged display-management registry with session-mobile Bazzite/SteamOS hosts and adds a per-launch dedicated gamescope mode. - A1 DisplayOwnership {Owned,External,SessionManaged} + poolable_now(): the registry pools only what it owns, so gamescope managed/attach outputs are no longer double-owned by the registry AND the gamescope restore worker (fixes the game-mode-reconnect stale-node wedge). - A2 validated reuse: (backend,mode,launch,epoch) reuse key + kept_display_alive liveness probe + reused_gen/mark_failed on a reused-display first-frame failure. - A3 policy-driven managed restore (keep_alive replaces the hardcoded 5s debounce; forever = held = gaming-rig truthful) + crash-restore persist + SIGKILL teardown (kill_unit, applied to our transient unit AND the autologin stop -- validated live on .181 to avoid the F44 GPU-context leak). - A4 session epoch: observe_session_instance bumps the epoch + invalidate_backend on a desktop-compositor instance change; gamescope spawns are exempt. - A5 per-spawn log + PID-scoped gamescope node discovery. - B0 game_session {auto,dedicated} policy (top-level, preset-orthogonal) + pick_gamescope_mode dedicated_launch + steam -silent command shaping. - B1 free the autologin Steam before a dedicated Steam spawn (single-instance). - B2 game-exit -> APP_EXITED_CLOSE_CODE (0x52) clean session end. Adversarially reviewed (11 findings fixed). Validated on glass (.181 Bazzite F44, RTX 4090): dedicated spawn streams a real game smoothly; keep-alive reuse; the SIGKILL fix avoids the F44 vkCreateDevice leak. Workspace green (build / test --workspace / clippy -D warnings / fmt), OpenAPI + C header regenerated, web console tsc + vite build green. clients/probe: bump the no-video timeout 8s->45s for gamescope cold starts.

enricobuehler	e8531a9eac	feat(vdisplay): harden keep-alive reconnect — same-client preempt, quit-skips-linger, configurable idle ... On-glass testing (Test 2, KWin .116) surfaced that a reconnect within the QUIC idle-timeout window (~8s) lands on a fresh SECOND display instead of reusing the kept one: the old session was still Active (not yet Lingering), so the registry's keep-alive reuse (which only matches Lingering) skipped it and the old session kept streaming to nobody. Three fixes: #3 Same-client reconnect preempt (the real fix): admission::preempt_same_identity() lists a reconnecting client's OWN still-live session(s) (same cert fingerprint); serve_session signals their stop + waits the release grace BEFORE acquiring, so the zombie tears down → its display lingers → the reconnect REUSES it instead of making a second. Implements the "preempts downstream" the admission docs already promised. Independent of the mode_conflict policy; the pure core (same_identity_stops) is unit-tested. #2 Deliberate quit skips linger: a client that deliberately disconnects closes the QUIC connection with QUIT_CLOSE_CODE (0x51, shared in core::quic); the host reads the ApplicationClosed reason and tears the display down immediately (registry release() gained force_immediate → Linger::Immediate; multi-session-safe via the pure lifecycle machine), while a bare disconnect still lingers for reconnect. Threaded via a session quit flag → the DisplayLease. NativeClient::disconnect_quit() + punktfunk-probe --quit drive it; GameStream (Quit App / h_cancel) is a documented follow-up. #1 Configurable disconnect-detection latency: the QUIC control-connection idle timeout (stream_transport, 8s default) is host-tunable via --idle-timeout-ms / PUNKTFUNK_IDLE_TIMEOUT_MS, clamped >=1s with a keep-alive that scales to it so a live session never false-closes. Default unchanged (8s stays load-bearing for the Windows IDD-push reconnect flow). Workspace check + 63 core / 215 host / 47 vdisplay tests green; clippy clean.

enricobuehler	0c2808bb4c	perf(gamestream): move FEC packetization off the encode loop (3-stage pipeline) ... FEC/Reed-Solomon packetization ran inline on the encode loop (~3 ms/frame at 4K), serializing behind encode and capping the GameStream frame rate below what the encoder alone can sustain. Split it into a 3-stage pipeline, each stage on its own thread joined by a depth-2 bounded queue: encode loop → [raw AUs] → packetizer (FEC/RS) → [wire batch] → paced sender - `spawn_packetizer`: turns each `RawFrame`'s access units into wire datagrams via the stateful VideoPacketizer, off the encode loop. Above-normal priority (on the per-frame critical path). Tallies goodput (bytes to the wire) for the stats window. - Backpressure chains up: a slow sender blocks the packetizer, which fills the encode→packetizer queue, which makes the encode loop drop the NEWEST frame — encode itself never waits. - A dropped frame now consumes no client-visible frameIndex (packetization is downstream), so the host re-anchors the reference chain: a drop arms a keyframe on the next iteration (`recover_after_drop`), routed through the same coalesce gate as client IDR requests so a burst of drops (congestion) can't become an IDR storm. - Perf/stats relabeled: `pkt` = AU drain, `send` = enqueue to the pipeline (both should be near-zero now; nonzero = encode being stalled by pipeline backpressure). Goodput read from the packetizer's atomic at the 1 s stats boundary. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-05 13:53:43 +00:00
enricobuehler	43e035de41	feat(vdisplay/kwin): group-aware exclusive — never disable a sibling output (Stage 5 §6.1) ... The critical latent bug Stage 3 introduced: per-slot output names mean a 2nd exclusive session's other_enabled_outputs() (which disabled 'everything not named Virtual-punktfunk') would black out the 1st session's Virtual-punktfunk-<id> output. Fix: recognise the whole managed group by the shared Virtual-punktfunk prefix — exclusive now disables only NON-managed outputs (bootstrap/physical), never a group sibling. Plus first-slot-wins for the group primary (a_managed_output_is_primary): a later session joins as a secondary monitor of the shared desktop instead of stealing the shell off the first. Unit-tested. Start of Stage 5 (§6A many-clients-one-desktop). Remaining: Mutter/wlroots group-aware analogues, layout (auto-row/manual + /display/layout + console), per-group topology restore, gamescope groups.

enricobuehler	a613f16b7d	fix(vdisplay): Windows admission default is reject, not join (single-capturer limit) ... Two concurrent Windows sessions both drive the same pf-vdisplay monitor's single-capturer IDD-push channel (newest-delivery-wins), which freezes the live client and can wedge the driver (observed live: a concurrent-session test wedged .173 → Moonlight 'no video'; needed a reboot). True multi-session capture is §6.6/ Stage 7. So on Windows 'separate' (incl. the unconfigured default) now resolves to REJECT — a 2nd client gets a clean 503 and the live session is protected — instead of join (which would freeze it). join/steal stay explicit opt-ins; Linux keeps separate (real multi-view).

enricobuehler	6ddce1049b	feat(vdisplay): finish Stage 4 — typed reject, Windows join-default, GameStream 503 ... Completes the mode-conflict admission surface deferred from the initial Stage 4: - REJECT now delivers the reason to the client: punktfunk/1 closes the QUIC connection with a distinct BUSY code (0x42) + the 'host busy: streaming WxH@Hz to <client>' string, which the client reads from ApplicationClosed (validated on loopback: the probe logs 'closed by peer: host busy … (code 66)'). - Windows default: separate (incl. the unconfigured default) resolves to JOIN — the Windows native host admits a second client at the live mode instead of the old silent last-wins reconfigure of the shared monitor (release-note behavior fix; the reconfigure is now opt-in as steal). separate stays multi-view on Linux. - GameStream 503: h_launch tracks the session owner fp (LaunchSession.owner_fp, kept [u8;32] for Copy) and applies the policy when a DIFFERENT paired client launches — reject → 503 (Moonlight 'host busy'), join → serve the live mode, steal/separate → take over. Same-client re-launch is never a conflict. Native reject-reason loopback-validated; Windows join-default pending .173 rebuild; GameStream 503 pending a Moonlight client (can't drive /launch autonomously).

enricobuehler	ed0881a9b9	feat(vdisplay): Linux keep-alive pool — registry-owned display lifecycle (Stage 1b) ... The ownership split (design/display-management.md §3): the registry owns the per-session virtual-display lifecycle on Linux, so a display can outlive its session (keep-alive) and be reused on reconnect. - registry.rs: a Linux pool driven by the pure lifecycle machine. acquire() reuses a kept (lingering/pinned) display of the same backend+mode, else creates one and keeps the backend's keepalive so the compositor output (and its PipeWire node_id) survives the session. The session's capturer holds a gen-stamped DisplayLease instead of the real keepalive; its drop drives linger/teardown. Enabling fact: KWin/Mutter/gamescope put their node on the DEFAULT PipeWire daemon (remote_fd=None) — reconnect re-attaches by node_id, no fd re-open. wlroots (remote_fd=Some, xdpw portal) passes through unchanged (teardown-on-drop) pending the fresh-portal-capture re-attach. - Default (unconfigured) linger = Immediate → today's teardown-on-disconnect, so no behavior change without a keep-alive policy; concurrent sessions still each create their own output (reuse only matches LINGERING entries). - Wired build_pipeline (punktfunk1) + gamestream through registry::acquire; capture_virtual_output signature unchanged. Windows delegates to vd.create (the manager already leases) — unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-04 23:37:21 +00:00
enricobuehler	c33bdeab15	fix(windows-host): cross-plane IDD serialization, linger-expiry race, second-host guard ... Batch C of the audit's medium tier (M7+M8+M9): - M7: GameStream sessions now run the same begin_idd_setup dance as punktfunk/1 before creating the shared monitor. A GS connect could previously ADD/reconfigure the monitor while a native session was mid-build (and vice versa), and its sealed-channel delivery replaced the native ring (newest-wins) — each plane could freeze the other. GS has no cooperative stop plumbing, so it registers a flag nobody reads: a later session signals it, waits the 3 s grace, then force-preempts — the intended handover. - M8: the linger-expiry teardown now runs UNDER the state lock. Running it outside let a concurrent acquire see Idle and ADD+isolate while the old monitor's pinger-join / CCD-restore / REMOVE were still in flight — a failed or de-isolated session exactly at the expiry boundary. A racing acquire now waits the few teardown seconds instead. Lock order stays state → device everywhere; the pinger takes only the device lock. - M9: a named mutex (Global\punktfunk-vdisplay-manager) makes a SECOND host process fail its vdisplay open loudly instead of firing a startup CLEAR_ALL that razes the live host's monitors mid-stream (the admin footgun the shared watchdog then masked).

enricobuehler	03ad2406b6	fix(host/windows): layout-correct keyboard injection - semantic vs positional VKs ... First-party punktfunk clients send US-positional VKs (the physical key's US-layout VK), GameStream/Moonlight clients send layout-semantic VKs (Sunshine's model). The SendInput injector previously resolved everything through the SYSTEM service's layout - on a German host that is the y/z swap and u-umlaut-on-o-umlaut scramble. GameStream ingest now tags its key events KEY_FLAG_SEMANTIC_VK (stripped from punktfunk/1 wire events so a network client can't flip the convention); the injector maps semantic VKs under the foreground app's layout and positional VKs through a fixed scancode table.

enricobuehler	138a6ed57d	fix(host): make client game launches work on every Linux compositor ... Client-initiated launches (Hello.launch / GameStream applist) were only wired to gamescope's bare-spawn path via the process-global PUNKTFUNK_GAMESCOPE_APP env — which leaked across sessions, was never read by kwin/mutter/wlroots (launch was a silent no-op there), and was unreachable on gamescope anyway because apply_input_env unconditionally defaulted to the managed session (which bails on non-Bazzite/SteamOS boxes and ignores the launch command in all its modes). - Thread the launch per-session: resolve the library id at handshake, carry it on SessionContext (Windows: id; else: resolved command), and hand it to the backend instance via set_launch_command — the global env write is gone (the env stays as an operator fallback in spawn). - Gamescope sub-mode ladder (pick_gamescope_mode, pure + unit-tested): managed only when session-plus/SteamOS infra exists, attach for an explicit request or a foreign (non-host-descendant) gamescope, else bare spawn — which nests the launch and is now reachable on plain distros instead of the guaranteed managed-mode bail. - launch_session_command: one launch entry point for both planes once capture is live — desktop compositors plain-spawn into the retargeted session (the virtual output is primary); managed/attached gamescope spawns with the live session's DISPLAY/GAMESCOPE_WAYLAND_DISPLAY discovered from /proc (steam:// URIs also forward over Steam's own pipe). launch_is_nested gates bare spawn against double-launching. - GameStream unified onto the same dispatch; also nests library-id picks into gamescope (previously only apps.json cmd was nested). Validated live on the dev box up to the missing-GPU wall: handshake resolution, Spawn sub-mode on plain Ubuntu, gamescope spawned with the command nested. On-glass validation (kwin spawn on the streamed output, Bazzite/Deck managed forward) pending GPU reattach. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-01 22:02:52 +00:00

Docs - "Console login password" section on every host page (apt/RPM/Bazzite/SteamOS/Windows) plus a new "Forgot your Password?" troubleshooting page, linked from the login screen. - Console served as HTTP/1.1 over TLS (drop the unusable HTTP/3 advertising) across the Bun entry, launchers, systemd units, and packaging.

enricobuehler	ce060d5c49	feat(gamestream): advertise HDR + surface the game library (with covers) to Moonlight ... Bring the GameStream/Moonlight plane up to the native plane's capability parity. HDR (Windows only): - New host_hdr_capable() gate (Windows + PUNKTFUNK_10BIT, matching the native policy). serverinfo layers SCM_HEVC_MAIN10 onto the probed/static codec mask, so Moonlight finally offers its HDR toggle (live: mask 0x10101 -> 0x10301). - Parse the client's dynamicRangeMode into StreamConfig.hdr and pass it through to OutputFormat::resolve, so a client HDR request proactively enables advanced color on the per-session virtual display (PQ flows even from an SDR desktop). The encoder bit depth now derives from the captured frame format (gs_bit_depth) rather than a hard-coded 8 that mislabeled the already-Main10 HDR stream. Game library in /applist: - The catalog now layers library::all_games() (Steam/Epic/GOG/Xbox/custom) on top of Desktop/apps.json, each with a STABLE GameStream id (FNV-1a, dedup-probed) and the store-qualified library id. Launch routes through the existing security-reviewed launch_title/launch_command via library::launch_gamestream_library — a client can only pick an existing title, never inject a command. - /appasset cover proxy: Moonlight fetches per-app covers from the host, so resolve appid -> library cover URL and proxy the bytes (portrait -> header -> hero -> logo; data: + bounded http(s) fetch), on a blocking thread. IsHdrSupported reflects the host HDR capability. 4:4:4 stays off on GameStream by design: stock Moonlight is 4:2:0 and the Windows IDD-push capturer can't deliver full chroma yet (capturer_supports_444() == false); the gate is documented so it lights up once IDD-push full-chroma capture lands. Validated live (Moonlight -> Windows NVENC host): HDR advertised, the Epic library shows with covers, launch works. clippy clean; apps/serverinfo/library unit tests cover the HDR mask, stable-id, dedup, and data-URL paths.

enricobuehler	0ff4373abd	fix(windows/gamestream): create the virtual display on Windows (Moonlight black screen) ... The GameStream video path (open_gs_virtual_source) ran the Linux compositor- detection state machine on every platform. On Windows detect_active_session() returns None and vdisplay::detect() bails ("could not detect compositor ... XDG_CURRENT_DESKTOP=''"), killing the video thread right after RTSP PLAY — so a Moonlight client paired, negotiated, then black-screened and dropped. The native punktfunk/1 path already guards this (resolve_compositor returns a placeholder Compositor on Windows, since vdisplay::open ignores the compositor arg there and always uses the pf-vdisplay IddCx backend). Mirror that guard in the GameStream path: short-circuit to a placeholder on Windows, keep the Linux session detection (apply_session_env/apply_input_env) under cfg(not(windows)). Validated live: Moonlight -> this box now creates the pf-vdisplay virtual monitor, attaches the IDD-push ring, and NVENC streams 5120x1440@240.

enricobuehler	7cc2ed85cb	feat(proto/steam): M3 — rich Steam wire (back buttons + 2nd trackpad) ... Carry the rich Steam Controller / Steam Deck inputs end-to-end on the wire — strictly additive + forward-compatible (unknown kinds/bits drop on old peers). Core (punktfunk-core): - input.rs: BTN_PADDLE1..4 + BTN_MISC1 in Moonlight's buttonFlags2<<16 namespace (so the GameStream paddle path and native grips share one host injector map; Steam L4/L5/R4/R5 reuse the four Xbox-Elite paddle slots). - quic.rs: RichInput::TouchpadEx (kind 0x03 — surface 0/1/2, touch+click, signed coords, pressure; the second trackpad the single Touchpad can't express) and HidOutput::TrackpadHaptic (kind 0x04 — the SC voice-coil pulse). Round-tripped. - abi.rs: PUNKTFUNK_GAMEPAD_STEAMDECK=6 / _STEAMCONTROLLER=5, the paddle bits, RICH_TOUCHPAD_EX / HIDOUT_TRACKPAD_HAPTIC constants. from_hid packs TrackpadHaptic into the existing which + effect[0..6] — the legacy structs do NOT grow (guarded by new size_of==20/19 asserts); GamepadPref lockstep + paddle-bit lockstep asserts extended. include/punktfunk_core.h regenerated. Host (punktfunk-host): - steam_proto::from_gamepad maps the wire paddles -> the four Deck grips + QAM; apply_rich routes TouchpadEx left/right -> the matching pad. - every DualSense/DS4 manager (Linux + Windows) gained a TouchpadEx arm (surface 0/2 -> its one touchpad; surface 1 ignored) so the variant compiles everywhere and a Steam client streaming to a DS host keeps its right pad. - the xpad BUTTON_MAP finally consumes the GameStream paddle bits (BTN_TRIGGER_HAPPY5-8) — Sunshine/Moonlight paddle clients were silently no-op'd before (design §5.6). - Android feedback: drop TrackpadHaptic (no coils; rumble rides 0xCA). Validated on-box: the ignored backend test now drives the full wire path — from_gamepad (BTN_A + the L4 grip) + apply_rich (a left-pad TouchpadEx) reach the evdev as BTN_A + ABS_HAT0X=-8000. Wire round-trips + paddle/TouchpadEx mapping unit-tested. Workspace clippy/fmt/test green. Not pushed. Deferred to M4: the C-ABI PunktfunkRichInputEx + send_rich_input2 (only the Apple/embedder *send* path needs it; the host decodes TouchpadEx today).

enricobuehler	c0e4a6e690	fix(host/gamestream): correct the rsa-Marvin (S7) rationale + cap pairing signatures ... Red-team found the .cargo/audit.toml justification for RUSTSEC-2023-0071 was materially wrong: it claimed "Marvin targets decryption, so the vulnerable path isn't exercised" — but the advisory is a variable-time modexp of the secret exponent, which RSA *signing* (signing_key.sign) also runs. The accept is still correct, for the RIGHT reasons (no decryption/padding oracle; the signed serversecret is host-random not attacker-chosen; signing is operator-PIN-gated; GameStream is off by default and the native QUIC plane uses rustls, not rsa; Moonlight mandates RSA-2048 so the GameStream key can't move off it). Rewrite the rationale accordingly. Also shut the timing-sample amplifier the review surfaced: the pairing session was never marked after phase 3, so a peer past phase 1 could loop phase2/phase3 to harvest many RSA signing-time samples. Sign exactly once per ceremony (reject a repeated serverchallengeresp). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-29 19:17:37 +00:00
enricobuehler	59e04aec99	chore(deps): drop unmaintained rustls-pemfile; axum-server 0.7 -> 0.8 ... axum-server was used only for the plain-HTTP nvhttp listener, but we enabled its tls-rustls feature (HTTPS is hand-rolled over tokio-rustls) — and that feature was what pulled the unmaintained rustls-pemfile (RUSTSEC-2025-0134). Drop the feature, bump axum-server to 0.8 (0.8 also no longer pulls it), and move our own PEM parsing in gamestream/tls.rs to rustls-pki-types' PemObject (the same path punktfunk-core/quic.rs already uses), removing our direct rustls-pemfile dep too. Net: rustls-pemfile fully gone; dependency graph trimmed 547 -> 529 crates (the tls-rustls feature also dragged in prettyplease + a wasm-tooling chain). cargo audit now reports only audiopus_sys + paste (transitive, latest, no successor). 108 host tests + clippy + fmt green.

enricobuehler	c1ce231dbf	fix(host/security): Windows DACL hardening — close audit #2, #3, #8, #11 ... Windows local-privilege findings from design/security-review-2026-06-28.md. These are #[cfg(windows)] paths (verify in CI / on the box; this Linux dev VM can't compile MSVC). They follow the existing write_secret_file/icacls patterns; the cross-platform parts are cargo check/clippy/test green. - #2 [HIGH]: route the mgmt bearer token write through the shared write_secret_file so it gets the SAME Windows DACL (SYSTEM/Administrators) as the host key — it was cfg(unix)-only and left Users-readable, leaking full mgmt admin authority to any local user. - #3 [HIGH]: create_private_dir now applies a restrictive DACL to the %ProgramData%\punktfunk config directory (re-owns to Administrators to defeat a pre-creation, strips inheritance, SYSTEM/Admins/OWNER full + Users read-only) so a local user can't plant host.env/apps.json that the SYSTEM service trusts (env/arg-injection LPE). host.env is now written DACL-locked via write_secret_file; the config + logs dirs go through create_private_dir. - #8 [LOW]: write the web-console password file empty, icacls-lock it, THEN write the secret — closes the brief write-then-icacls TOCTOU window. - #11 [LOW]: the SYSTEM logs dir is DACL-locked (Users read-only, no create), so a local user can't pre-plant host.log as a reparse/hardlink to redirect SYSTEM's writes (subsumed by the #3 dir lockdown). Deferred: #5 (host<->UMDF gamepad/IDD shared-section Everyone:GENERIC_ALL). The section SDDL is intentionally permissive because the UMDF driver opens it under a restricted token of unknown SID/integrity; scoping it blind would likely break the live-validated gamepad/IDD pipeline, so it needs on-box validation first. Tracked in the report. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-28 22:14:19 +00:00
enricobuehler	46b82d4eee	fix(host/security): close audit findings S1,#1,#4,#10,#12,#7,#6,S2-S6 (Linux/cross-platform) ... Remediations from design/security-review-2026-06-28.md verified on Linux (cargo check/clippy/test green; Windows-gated paths verify in CI): - S1 [HIGH]: bump quinn-proto 0.11.14 -> 0.11.15 (RUSTSEC-2026-0185, pre-auth out-of-order STREAM reassembly memory exhaustion on the always-on default QUIC listener). - #1 [HIGH]: remove the unauthenticated nvhttp `GET /pin` endpoint; the GameStream PIN is delivered ONLY via the bearer-gated mgmt API, so a network client can no longer submit its own displayed PIN and self-pair. - #4 [HIGH->MED]: gate the unauthenticated RTSP/UDP media plane on a paired `/launch` and bind it to the launching client's source IP (threaded through the HTTPS handler), so an unpaired peer can neither start capture on an idle host nor ride a paired client's active launch. - #12: bound concurrent parked pairing waiters (MAX_PARKED_WAITERS) so a pre-auth peer can't pin unbounded 300s handshakes. +regression test. - #10: throttle the per-packet ENet control GCM-decrypt-failed warn (exponential backoff) so a junk flood can't spam the log. - #7 [MED->LOW]: serialize all process-global env mutation on the session-setup path under a new vdisplay::ENV_LOCK (apply_session_env / apply_input_env / the launch-cmd set_var / the gamescope env read), so concurrent native sessions can't race set_var/getenv (data-race UB -> host-wide DoS). Full per-session SessionContext threading remains a follow-up for cross-session value confusion. - #6 [MED]: move the gamescope EIS socket relay from world-writable /tmp to $XDG_RUNTIME_DIR (per-user 0700) and reject a symlinked relay file, so a local user can't intercept (keylog) or deny the remote session's input. - S2: a malformed client Opus mic frame now drops that frame instead of tearing down the shared host-lifetime virtual mic (cross-session DoS). - S3: track held buttons/keys in capped HashSets (was unbounded Vec with O(n) scans) so a paired client can't grow per-session input state. - S5: reject fps==0/absurd at the open_video chokepoint (covers Hello, ANNOUNCE, Reconfigure) so the encoder time_base/pts math can't div-by-0. - S6: bound the shared mic mpsc (drop-newest when full). - S4: cap Epic launcher-cache reads (catcache.bin/.item) so a planted giant can't OOM the host during library enumeration.

enricobuehler	7612238a59	feat(audio): end-to-end 5.1/7.1 surround across the native path + all clients ... Adds negotiated 5.1/7.1 surround to the punktfunk/1 protocol and every client (previously stereo-only): - core: new shared `audio` layout table (LAYOUT_51/71 + identity multistream mapping, canonical wire order FL FR FC LFE RL RR SL SR); Hello/Welcome `audio_channels` negotiation via the trailing-byte back-compat pattern (old peers fall back to stereo); C-ABI `punktfunk_connect_ex6`, `punktfunk_connection_audio_channels`, and in-core multistream decode `punktfunk_connection_next_audio_pcm` for embedders without a multistream Opus decoder. Real-libopus channel-identity round-trip test. - host: native audio thread captures + Opus-(multi)stream-encodes at the negotiated count (with a cross-session cached-capturer channel-mismatch fix); GameStream surround unified onto the safe `opus::MSEncoder`, dropping `audiopus_sys` (~4 unsafe blocks) and un-gating Windows GameStream surround; WASAPI loopback capture relaxed to 2/6/8 with the correct dwChannelMask. - clients: Linux (PipeWire), Windows (WASAPI), Android (AAudio) decode via `opus::MSDecoder` + render multichannel; Apple decodes in-core to PCM → AVAudioEngine with an explicit wire-order channel layout; each gains a Stereo/5.1/7.1 setting. `punktfunk-probe --audio-channels N` is the headless validator. Verified on Linux: core/host/linux/probe test suites + the Android Rust (cargo-ndk) build, clippy -D warnings, and rustfmt all green. Windows/Apple builds, all on-glass checks, and the live native loopback are pending (CI / a free box). Also lands the concurrent in-tree HEVC 4:4:4 host work (PUNKTFUNK_444): it shares the same touched files (quic.rs, punktfunk1.rs, encode/*, ...) and so cannot be committed separately from the surround changes.

enricobuehler	6409bdb062	feat(host/gamestream): follow Desktop<->Game session switches ... The GameStream/Moonlight video plane is a separate encode loop that lacked the session-following the native punktfunk/1 plane has, so a mid-stream Desktop<->Game switch killed the stream ("video stream failed") instead of following it. * Normalize the session env like the native plane: extract open_gs_virtual_source, which detects the LIVE compositor + apply_session_env/apply_input_env (gamescope ATTACH default -> resize-on-attach to the box's own game-mode session at the client mode; KWin/Mutter retargeting). GameStream previously ran a bare detect() against raw process env, so in game mode it bare-spawned a COMPETING gamescope instead of attaching to the box's session. * In-place capture-loss rebuild: replace the `?` that ended the stream with a bounded rebuild (re-detect the live compositor via the same factory, build the new source BEFORE dropping the old, reopen the encoder, force an IDR) — keeping the send thread + packetizer + socket + RTP clock. A same-resolution Desktop<->Game toggle is now FOLLOWED with no Moonlight reconnect. Protocol limit (unchanged): a mid-stream RESOLUTION change is impossible on GameStream (WxH locked at ANNOUNCE; no Reconfigure) — a session toggle keeps the negotiated mode, so this isn't hit. The portal/synthetic source passes no rebuild closure (propagates as before). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-28 12:22:12 +00:00
