A drmtap context is bound to a single DRM device, so the service enumerated one
auto-detected card and advertised only its monitors. On a multi-GPU host every
display driven by another card was invisible to the client, and its card-local
CRTC id could not have been opened through the wrong device anyway.
The service now enumerates every card (drmtap_list_devices, libdrmtap 0.4.15),
opens one reader per device, and merges their displays into the one list, each
tagged with its own card node and render node. DrmStart resolves the chosen
index to that display's device + CRTC and the worker reopens the right card;
the converter already binds the display's render node. Both new fields are
serde(default) and empty means the single auto-detected device, so a pre-0.4.15
.so and a mismatched-build peer keep the previous behaviour exactly.
Enumeration replaces the single-reader open in the pre-warm, the udev hotplug
refresh, and the per-connection handshake, so a hotplug on any card is picked up
and an all-monitors-off state now correctly publishes an empty list. The
per-connection cache refresh re-enumerates all cards rather than only the
connection's device, so serving one display never drops the others from the
next handshake.
Verified on a Jetson Orin (its two DRM devices, only card2 driving a display):
list_devices reports card2/renderD129 with one display, enumeration produces
exactly that display tagged to card2, and card1 (no active CRTC) is skipped -
no phantom, no regression on the single-display case.
The unprivileged converter opened its render context with
drmtap_open_render(NULL), letting libdrmtap auto-select. On a multi-GPU host
that can land on a different GPU than the one driving the display, and importing
a scanout across vendors can fail permanently on an incompatible tiling
modifier.
The service already knows the exporting device, so it now names its render node
(drmtap_render_node, libdrmtap 0.4.15) in each DrmDisplayInfo, and the consumer
opens the converter on that node. The field is serde(default) and empty means
auto-select, so a service and a server from mismatched builds still interoperate
and a pre-0.4.15 .so degrades to exactly the previous behaviour. The path is
realpath-gated to /dev/dri before it is opened, the same gate the capture device
gets, since it arrives over IPC. When the named node cannot be opened the
converter returns None and the existing need_cpu fallback runs the convert on the
exporting GPU service-side, which is the most correct place for it anyway.
Added a wire-compat test that a pre-render_node DrmDisplayInfo payload still
decodes (empty node) and a current one round-trips the node.
Point the DRM capture build at the libdrmtap v0.4.14 release commit
(816766dedaba3140c613712ce97aa2614e8899e7) instead of v0.4.13, in build.py and
the flutter-build workflow, and correct the scrap Cargo.toml note to describe
the actual DRMTAP_SHA anchor. 0.4.14 keeps the same public API, so the dlopen
consumer needs no change.
5e: the deb dropped /usr/lib/rustdesk into /etc/ld.so.conf.d so the private libdrmtap
could be found by soname -- a system-wide search-path entry that lets it shadow a
system library for every binary on the host, which Debian Policy 10.2 forbids. Resolve
it by absolute path (/usr/lib/rustdesk/libdrmtap.so.0) at the dlopen site instead, with
the bare sonames kept only as a dev fallback, and drop the ld.so.conf.d file and the
ldconfig/try-restart postinst entirely (the .so is present at its absolute path right
after unpack, so the pre-warm resolves with no linker-cache step). The dlopen site is
this PR's own code, so this is in scope, not a follow-up.
6a: extract the _drm admission bound and the per-frame re-auth decision into pure
helpers (drm_conn_admitted, drm_peer_authorized) and unit-test them: admission admits
strictly below MAX_DRM_CONNS and rejects at/above it; re-auth passes root always,
passes a non-root peer only while it equals the active-session uid, and fails closed on
a switched-away, unknown-session, or unknown-peer case. (The /proc/exe-mismatch
rejection is exercised by the accept-time authorize call; unit-testing it in isolation
would need a second process with a different exe, so it stays an integration concern.)
3.1: snapshot the stock flutter bundle before the CI drm relink and restore it
before makepkg, so the official Arch package ships the stock cdylib, not the
drm-enabled one. 4.2: wrap the drm block in a failure-tolerant subshell so a
drm-only failure no longer aborts the stock deb/rpm/arch publish. 4.3: narrow the
publish glob to rustdesk-[0-9]*.deb so the consent-bypass unattended-wayland deb
stays an artifact, not on the public release. 4.4: rewrite the three stale
DRM_CAPTURE_SECURITY.md statements to the split (default path passes a read-only
scanout dma-buf fd over SCM_RIGHTS with an import-once cache; export validation is
metadata-only; BGRA-over-the-wire is the fallback) and document that grab_desc's
fd is O_RDONLY (DRM_RDWR dropped upstream, dup preserves it). 4.7: only
short-circuit to the DRM cursor when it is authoritative (visible, or hidden in a
pure-DRM session); fall through to the normal cursor path in a mixed
DRM+PipeWire session. minors: thread the deb variant by feature not glob; TODO
for the ld.so.conf.d system path; drop a stray blank line. All gated or
whitespace so the drm-off build stays byte-identical.
grab_desc exports the raw scanout dma-buf; the unprivileged converter handles
every format libdrmtap supports (10-bit XR30/AR30 with tone mapping, HDR, CCS)
down to RGBA. The fourcc gate copied from the CPU-mapped grab() wrongly closed
the _drm stream for a 10-bit XR30 primary (0x30335258) that convert_dmabuf
converts fine -- observed live on an i915 seat scanning out XRGB2101010. Keep
the gate only on grab(), whose frame.format is already the converted BGRA.
1- do not depend on the libdrmtap-sys crate for the pin: its build.rs statically
compiles the whole libdrmtap C tree and a CAP_SYS_ADMIN helper and links
-ldrm/-lseccomp/-lcap, which defeats the runtime-dlopen model. keep drm a pure
dlopen backend and pin the .so by the build.py DRMTAP_REF release tag, guarded by
a strict vX.Y.Z regex. drops the now-moot Cargo.lock freshness CI checks.
2- render-node-less consumers no longer lose the stream: the --server signals
need_cpu on DrmStart when it cannot open a convert context, and the --service
streams the CPU-converted frame path for that connection instead of a dma-buf fd
the consumer cannot detile (which used to fall through to a PipeWire path nobody
can approve on an unattended seat).
3- mark PipeWire initialized only after every per-display capturer is created, so
a partial failure retries instead of the flag falsely reporting a complete init.
4- reject a degenerate (zero width/height) or short CPU frame before it reaches
PixelBuffer::new (which derives stride as data.len()/height, dividing by zero).
5- keep the export-ledger epoch at DRM_DISPLAY_GENERATION so a hotplug invalidates
cached buffers (elision stays off until the recycled-fb_id inode case is handled).
6- validate the udev uevent source (kernel nl_pid, multicast) with recvmsg so a
local process cannot unicast a spoofed drm-change event to the root listener.
move the egl detile and rgba pack out of the root --service and into the
unprivileged --server. the root now calls only drmtap_open + drmtap_grab_desc
and exports a raw dma-buf fd; the fd rides the _drm channel over SCM_RIGHTS with
a small descriptor (geometry, per-plane offsets/pitches, modifier, hdr) instead
of the full rgba frame, dropping the per-frame copy. the --server imports the fd
with drmtap_open_render + drmtap_convert_dmabuf, keyed by the import-once egl
cache, and the render context is created and dropped on the recv thread.
the _drm transport moves off Framed<BytesCodec> (which cannot carry a fd) to a
bespoke sendmsg/recvmsg framing (DrmConn) that attaches one SCM_RIGHTS cmsg only
when a fd is present and rejects a truncated ancillary message. the split
symbols are bound optionally so an older libdrmtap still loads the cpu path, and
the whole thing degrades to the cpu BGRA path or PipeWire when no render node is
available. pins libdrmtap-sys to =0.4.13 with the Cargo.lock checksum. folds in
the DP-MST, ldconfig-restart and per-display PipeWire-fallback review fixes and a
udev hotplug refresh.
adds an opt-in `drm` feature for unattended remote access on Wayland: it
captures below the compositor via libdrmtap, so there is no
xdg-desktop-portal consent dialog and it works at the login screen.
off by default. when the feature is off the build is byte-identical.
everything is gated behind feature = "drm" or lives only in the separate
rustdesk-unattended-wayland deb, whose package name is the informed consent.
architecture (agreed with the maintainer): the capture runs inside the root
--service, which already holds the privilege it needs, and streams frames to
the user --server over a service-scoped _drm ipc channel. libdrmtap is loaded
with dlopen at runtime (no link-time dependency, so the base build is
unchanged and it still runs on ubuntu 18), and the .so is built in ci from the
rustdesk-org/libdrmtap fork and shipped only in the drm deb. no setcap helper.
- service: DrmReader reads scanout directly via the dlopen loader; an
IpcDrmCapturer serves _drm consumers with a per-connection capture worker;
durable availability cache + pre-warm to avoid enumerate/re-probe restarts
- capture: multi-display (targets the selected crtc), hardware cursor over
_drm, transient-errno retry with a bounded stall, rejects non-32bpp scanouts
before the frame copy
- robustness: only active, crtc-bound outputs are offered (an unbound
crtc_id=0 connector is filtered and a client-selected 0 is refused, both
fall back to pipewire); a per-display rapid-rebuild guard demotes a flapping
display to pipewire; per-display (not global) zero-frame failure tracking
- root-service hardening: bounded frame allocation and a concurrent-connection
cap so a malformed scanout or a buggy consumer cannot OOM or thread-exhaust
the service; a negative availability verdict expires so displays that appear
after startup recover without a --server restart; exactly-one .so selection
in the packaging so a stale object is never silently shipped
- build: libdrmtap.so cloned at build time from rustdesk-org/libdrmtap main
and bundled only for the --drm deb; ci builds a separate
rustdesk-unattended-wayland deb (incl. an ubuntu 18.04 container)
- DRM_CAPTURE_SECURITY.md: threat model and hardening notes
* fix: refresh wayland uinput range on compositor layout change
The uinput absolute range is computed once at session init. If the
compositor layout changes mid-session (monitor scale or position
change, or a portal virtual output appearing once capture starts),
injected coordinates are rescaled by the stale range and land offset.
Poll the live desktop bounding box from the display service loop while
subscribed (one wayland roundtrip, throttled to 1.5s, no subprocesses)
and re-apply the uinput resolution when it changes. Also read a fresh
layout when computing the initial range in check_init, since the cache
is not cleared when a session closes through the restore-token path.
This is the X component of #15601. The stale advertised origins (the Y
component) are not touched here: re-advertising DisplayInfo mid-session
trips the portal re-negotiation and can drop displays.

* fix: bound the mouse resolution IPC wait during session init
Wrap update_mouse_resolution in the same 3s timeout the periodic
refresh uses, so a hung IPC response can't stall check_init.

* fix: build timeout future inside runtime, split linux lazy_static
Constructing the timeout future eagerly as the block_on argument panics
with 'there is no reactor running'; move it into the async block so it is
built inside the runtime context. Also move WAYLAND_UINPUT_RECT into its
own cfg-gated lazy_static block, an attribute on a single item inside the
shared block does not compile.
* fix: confirm uinput mouse device adopted new range before caching rect
send_refresh() now waits for the mouse service to ack that it recreated the
device with the new range instead of firing and forgetting, and
update_mouse_resolution() propagates that result. The layout poller only
caches the rect after the device actually adopts the range, so a failed
refresh errors and retries on the next check. The ack read is bounded by
IPC_REQUEST_TIMEOUT, matching the keyboard get-key-state path.
* fix: propagate refresh failures instead of caching a stale range
- input_service: error when the custom-mouse downcast fails so the poller
retries instead of caching an unconfirmed refresh
- uinput: on device recreation failure, keep the current device and the
IPC connection and withhold the ack so the client retries, instead of
killing the mouse handler
* fix: remap injected wayland coords onto the live layout after a monitor moves
The range refresh corrects the uinput ABS bounds, but a single-display client
sends whole-desktop coordinates offset by the origin of the display it follows,
taken from the layout advertised at session init. When another monitor is
rescaled or moved that origin shifts, so the coordinate lands offset before it
reaches uinput and the range refresh cannot recover it.
Snapshot the per-display layout at init, poll the live layout on the existing
1.5s throttle, and when they differ remap each injected move into the followed
display's current rectangle (matched by connector name, index fallback when the
compositor reports none). No-op and lock-free while the layout is unchanged.

* address copilot review findings in wf_cliprdr.c
- Reject a negative FILECONTENTS_SIZE result: m_lSize is unsigned, so a
negative value became a huge bogus stream size that keeps reads going.
- Use a unique per-stream counter as the CLIPRDR streamId instead of a
truncated IStream pointer, which could collide or be reused after free
(and leaked heap addresses to the peer).
- Add req_f_request_mutex to serialize whole file-contents request/response
cycles, enforcing the previously assumed one-outstanding-request
invariant when multiple streams are read concurrently. Bounded acquire
so a wedged request fails the read instead of hanging a consumer.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* serialize file-contents request state and poison streams after timeout
- Extract lock_mutex() for the WAIT_OBJECT_0/WAIT_ABANDONED idiom shared by
take_req_fdata, the request-serialization acquire, and the response handler.
- Collapse the acquire/send/take/release cycle into
cliprdr_request_filecontents_sync(), used by CliprdrStream_Read and the size
probe in CliprdrStream_New.
- Publish req_f_stream_id_expected/req_f_size_requested under req_f_mutex in the
sender and read them under the same lock in the response handler, removing the
cross-thread data race on those fields.
- Poison a stream (m_failed) after a request fails/times out, so a late response
carrying a previous offset's bytes cannot satisfy a later same-stream read.

* key the responder stream cache on connID as well as streamId
Per-stream ids restart from 1 in each peer process, so two connections can
emit the same streamId. The process-static pStreamStc cache keyed only on
streamId could then serve one peer the IStream cached for another peer (a
different file), silently returning wrong-file bytes. Add connID to the key.

* harden the format-data path against late/duplicate responses
The format-data rendezvous had the same single-slot race the file-contents
path just fixed: the channel thread rewrote clipboard->hmem with no lock while
explorer-thread consumers read/freed it, nothing serialized concurrent
requests, and no flag told an expected response from a stray one.
- Add format_request_mutex (serializes the whole request/response cycle) and
hmem_mutex (guards the hmem hand-off and formatDataRespExpected).
- cliprdr_send_data_request now takes ownership of the response buffer under
hmem_mutex and returns it to the caller, so a later response cannot touch a
buffer a consumer is using. All three consumers (GetData, WM_RENDERFORMAT,
DELAYED_RENDERING) and the WM_CLIPBOARDUPDATE cleanup use the returned/taken
handle instead of the shared slot.
- The response handler drops any response arriving while formatDataRespExpected
is clear (late/duplicate/unsolicited), consumes the flag on the first
response, and no longer dereferences a NULL clipboard in the SetEvent path.
Pre-existing issue, not introduced by this branch; generalizes the
file-contents hardening to the format-data path.

* fix(clipboard): make CLIPRDR format-map growth checked
The Windows CLIPRDR format-list handler relies on map_ensure_capacity()
while processing peer-provided formats. The previous helper only attempted
growth: if realloc() failed, it returned silently and the caller continued
processing. A later iteration could then index past the allocated
format_mappings array.
Make format-map growth a checked operation. The handler now validates the
peer-provided format count, ensures the mapping array is large enough before
writing entries, and aborts processing if growth fails. Newly allocated slots
are zeroed so existing cleanup can safely run after partial processing.
Also bound remote format names before measuring/converting them. The chosen
limits follow Windows clipboard/atom constraints:
- registered clipboard format IDs use 0xC000..0xFFFF
- string atom names are limited to 255 bytes

* Support controller user attribution in audit logs
This PR supports associating audit logs with the controller user.
## Implementation:
- Add `ControlledContext { conn_audit_token }` to `PunchHole`, `RequestRelay`, and `FetchLocalAddr`.
- The server sends a controller-user identity snapshot to the controlled client through rendezvous messages.
- The controlled client sends the token back to the server when posting the `on_open` conn audit or IP whitelist alarm audit.
- This lets the server attach the controller user to audit logs.
## How the controlled client helps identify the controller user:
- Conn audit: sends the token to the server in `on_open`; the server creates the audit log and caches the user snapshot.
- File audit: sends `id` and `conn_id`; the server uses them to find the cached user snapshot.
- Alarm audit: IP whitelist sends the token directly; other alarm logs send `id` and `conn_id`, and the server uses them to find the cached user
snapshot.
## Compatibility:
- Supported only for logs created with a new server and a new controlled client.
- Does not require upgrading the controller client.
## Test
- [x] New/old clients connected to new/old servers, and conn/file/alarm audit logs worked normally.
- [x] New client connected to new server generated searchable conn/file/alarm audit logs.
- [x] Punch hole, local addr, and relay paths worked with audit logs and control role on new/old servers.
- [x] Direct IP connections produced audit logs, but do not support user audit.

On Wayland compositors whose xdg-desktop-portal backend exposes screencast
frames as DMA-BUF buffers — notably xdg-desktop-portal-cosmic 0.1.0 on
Pop!_OS 24.04 / COSMIC — inbound screen capture fails. PipeWireRecorder
links pipewiresrc directly to an appsink whose caps only accept
video/x-raw BGRx/RGBx in system memory. That format set is too narrow for
the portal's buffer-type / modifier negotiation, which collapses with:
pw.link: negotiating -> error no more output formats (-22)
gstpipewiresrc: stream error: no more output formats
gstbasesrc: streaming stopped, reason not-negotiated (-4)
ERROR src/server/wayland.rs: Failed scrap Element failed to change its state
Inserting a videoconvert element between pipewiresrc and appsink widens
the negotiable format set to any system-memory video/x-raw format, giving
the portal room to settle on a format it can deliver via its SHM path.
videoconvert then converts to the BGRx/RGBx the appsink expects.
Verified on Pop!_OS 24.04 / COSMIC with gst-launch, before and after:
# fails (current behaviour):
gst-launch-1.0 pipewiresrc path=N ! video/x-raw,format=BGRx ! fakesink
# works (with this change):
gst-launch-1.0 pipewiresrc path=N ! videoconvert ! video/x-raw,format=BGRx ! fakesink
After the change, inbound connections capture and stream the desktop
normally and the "Failed scrap" error no longer occurs.
