enricobuehler 134fba1424 fix(inject): heap the SwDeviceCreate callback context; stop latching a pad slot on a failed create
Two medium findings from the round-1 sweep, each applied to both siblings.

- create_swdevice stack-allocated the SwCreateCtx that the async PnP completion
  callback writes through (result + up to 127 u16 of instance id) and then
  SetEvents. The wait is bounded at 10s, so on a wedged-PnP timeout the callback
  can still be PENDING: the frame is popped, the input thread reuses that stack,
  and a late callback corrupts it and SetEvents an already-closed (possibly
  recycled) handle. The context is now heap-allocated and reclaimed only where
  the callback provably ran; on the timeout path the box is deliberately leaked
  and the event left open, so a late write always targets live memory. Costs a
  one-off ~264 B + one HANDLE on that rare path. Applied to the DualSense path
  and its XUSB sibling in gamepad_windows.rs.

- Ds4WinPad::open swallowed a create_swdevice failure into a WARN and returned
  Ok with no devnode. PadSlots::ensure then stored Some(pad) AND called
  gate.on_success(), so the slot short-circuited on is_some() forever and the
  capped-backoff retry that exists precisely to self-heal a transient PnP failure
  never ran — the game saw no controller for the rest of the session unless the
  client unplugged the pad. Now propagates, matching the XUSB sibling. Same fix
  applied to steam_deck_windows.rs.

Windows .173: pf-inject 53/0. Linux .21: pf-inject 74/0 (8 ignored).

enricobuehler 986402f731 fix(inject,zerocopy,capture): teardown deadlock, GL→CUDA copy race, cursor-meta OOB read
The three high-severity defects from the round-1 sweep of pf-inject /
pf-zerocopy / pf-capture (adjudicated against source — all 7 reported criticals
in these crates downgraded; these were the real highs).

- pf-inject steam_gadget: `SteamDeckGadget::drop` set `running=false` then joined
  the control thread, which spends steady state parked in a blocking, no-timeout
  `EVENT_FETCH` ioctl that only tests `running` at its loop top. The flag never
  reaches it, closing the fd can't wake an in-flight ioctl (the syscall holds a
  file reference, and the fd is shared via Arc by the very threads being joined),
  so the join hung — and it runs on the session input thread via
  `PadSlots::sweep`, driven by the client's `active_mask`, so a remote peer
  clearing its pad bit could freeze all session input. Now wakes the parked
  threads with SIGUSR1 (no-op, non-SA_RESTART handler → the ioctl returns EINTR
  and the loop exits), retried until each reports done and bounded (~1s).

- pf-zerocopy cuda: the GL→CUDA "sync point" was never established for the copy.
  `cuGraphicsMapResources`/`UnmapResources` were issued on the NULL stream, but
  the D2D copy runs on `copy_stream()`, a `CU_STREAM_NON_BLOCKING` stream exempt
  from implicit NULL-stream ordering — and the GL de-tile/CSC that produced the
  texture ends with only `glFlush` (no fence). So the copy could race ahead of
  the not-yet-retired GL draw: intermittent stale/torn frames under GPU load, on
  the default NVIDIA capture→encode path. Map, copy, and unmap now share
  `copy_stream()`, so map's device-side guarantee orders the GL work before the
  copy. Zero-copy preserved (no GPU→CPU→GPU roundtrip).

- pf-capture cursor meta: `update_cursor_meta` trusted three producer-written
  fields (bitmap_offset, pixel offset, stride) with no bound against the metadata
  region, driving OOB pointer arithmetic and an oversized `from_raw_parts` — an
  OOB read that SIGSEGVs inside the PipeWire `.process` callback (uncatchable by
  the surrounding `catch_unwind`). Switched to `spa_buffer_find_meta` to obtain
  the region's real `size` and validate every offset with checked arithmetic
  before each deref/slice, mirroring the fd-length guard the main frame path
  already applies.

Compile + existing tests green on Linux .21 (real RTX 5070 Ti): pf-inject 74/0,
pf-zerocopy 17/0, pf-capture 1/0. The gadget deadlock path only executes on a
SteamOS host with raw_gadget/dummy_hcd (not reproducible on the CachyOS box), so
that fix is reasoned + compile-verified, not runtime-exercised.

MINOR, not patch: 31 commits since v0.13.0 carry 10 features, including a new
/api/v1/plugins surface with a regenerated OpenAPI spec + SDK client. Since
sdk-publish pushes this version to consumers, a patch bump would understate a
new API surface for anyone pinning ~0.13.

Headline work: GNOME 50 HDR screencast capture + Linux Main10 encode, PyroWave
4:4:4 + HDR end to end (Linux/Windows/Apple), the console-hosted plugin UI
surface, and the pyrowave perf work that lifted the 2.5 Gbps wall. Notable
fixes: the RSA host-identity keygen that broke every fresh Windows install on
0.13.0, and SDR negotiation on the Windows IDD-push path.

pf-clipboard / pf-inject / pf-vdisplay were still hardcoding 0.12.0 — the three
the 22b352c1 sweep missed. Switched to version.workspace = true so the next
bump stays one line. (fec-rs, pf-driver-proto and usbip-sim are deliberately
versioned independently and stay put.)

enricobuehler 9e6fc6e071 fix(host/inject,drivers): rumble root fixes A-C — lossless report ring + rumble-keyed idle watchdogs
B: PadFeedback.game_drove -> rumble_drove, keyed on vibration-asserting reports — an
LED/adaptive-trigger stream can no longer feed the abandoned-rumble force-off while a
coalesced stop never re-asserts (the confirmed unbounded stuck-ON path). C: Linux parity —
every UHID backend now arms the shared watchdog (Steam Input drives these pads over hidraw
with Windows abandonment semantics) and the uinput mixer force-stops abandoned
infinite-replay FF effects (FfState, unit-tested). Shared PUNKTFUNK_RUMBLE_IDLE_MS hatch
(0 = off; non-zero floored above SDL's ~2 s rumble resend).

A: PadShm v2.1 — a 1024 B tail extension carrying an 8-slot lossless output-report ring,
feature-negotiated via zeroed reserved fields (out_ring_ver; deliberately NO
GAMEPAD_PROTO_VERSION bump — mixed generations degrade to the legacy latest-report slot
instead of failing closed). The pf-dualsense driver dual-writes both planes
(publish_output); the host's shared OutputDrain drains oldest->newest with a torn-read
recheck and an overflow->resync path (PadFeedback.resync force-stops + re-arms dedups).
pf-umdf-util grows a min_data_size map fallback. Ds*Feedback.fresh removed (dead).

design/rumble-root-fix.md par. A-C. Verified: pf-inject tests+clippy Linux+Windows (53/53
on winbox incl. the stop-coalesce repro); drivers ws check+clippy on the CI runner.

enricobuehler f6c6e4e594 refactor(host/W6.2): extract the input-injection backends into the pf-inject crate
inject.rs + inject/* (the per-OS injectors — wlroots virtual-input, KWin
fake_input, libei/reis, gamescope-EI on Linux; SendInput on Windows — plus the
virtual-gamepad HID stack: DualSense/DualShock4/Switch Pro/Steam Controller/Deck
over uhid/usbip and the Windows UMDF drivers, the proto codecs, the injector
service, and the uhid manager) move into crates/pf-inject behind the
InputInjector trait (plan §W6). It consumes punktfunk_core::input (the neutral
GamepadEvent/InputEvent vocabulary, moved to core in W5) + the pf-driver-proto
wire contract, and reaches pf-capture only for the Windows gamepad-channel
WUDFHost check + the resident-mouse compose-kick hook.

The one inject->vdisplay coupling (the libei gamescope-EI backend needs the EIS
relay socket path) is broken via a leaf: gamescope_ei_socket_file moves to
pf-paths as the shared contract — the gamescope producer (host vdisplay) keeps
its session-env-lock wrapper around it, the libei consumer (pf-inject) reads it
directly post-retarget. The host keeps a `mod inject { pub use pf_inject::* }`
shim so every crate::inject::* path (the native/gamestream input planes + devtest)
is unchanged; the heavy input deps (wayland/reis/xkbcommon/usbip + the KWin
fake-input protocol XML) moved with the crate.

Verified: Linux clippy -D warnings (pf-inject + host nvenc,vulkan-encode,pyrowave
--all-targets) + pf-inject 69/69 + host 230/230 tests; Windows clippy -D warnings
(pf-inject --all-targets + host nvenc,amf-qsv --all-targets) Finished exit 0.
