apple removed postscript support, so switch to PDF printer if running on
mac os sonoma (14) or newer. Requires windows 10 or newer or a custom
PDF printer driver
Since complete sound frame is already available, just write it out to
pulseaudio stream using more efficient pa_stream_begin_write API.
This removes a few milliseconds of pure wait time from each play call and
makes audio playback a bit smoother.
PAKID_CORE_USER_LOGGEDON might happen in quite a lot of combinations not
obvious from the spec at first glance. Relax state checks so that all
valid combinations are allowed.
It seems like some windows servers don't like to receive ack frame messages
with a totalDecodedFrame number that is bigger than the frameId.
That can happen if the connection starts, some frames are decoded, we receive a
renegotiate message, then egfx channel is reopened and the frame ids we receive
go back to 1. In the previous situation, we ended up with sending an ack
with frameId=1 and totalDecodedFrames=38, with the patch totalDecodedFrames is
reset when receiving caps, so it's always lower than frameId.
The mouse cursor channel enables remoting of the mouse cursor (bitmap)
over a DVC. The main use case is UDP, as only virtual channels can be
transported via UDP in RDP.
With the location channel, an RDP server can redirect the location of
the user from the client side to the server side.
The PDUs are almost the same as in the documentation, except for the
encoded types, these ones are here already parsed.
Optional values are accessed via pointers. If the pointer of a value is
NULL, then that value was not supplied by the client side.
C requires prototypes or compilers will complain about them missing. Our
library entry points do not have such, therefore add the macro
FREERDP_ENTRY_POINT which declares the function prototype automatically
before the function.
changed the signature of the backend loader function. the previous
version casted the allocated pointer to UINT which might not be able to
hold a pointer.
This PR fixes an issue caused by clipboard format filtering which
discarded all formats but `FileGroupDescriptorW` to enable clipboard
file transfer. However at least on windows we also need `FileContents`
to be placed in the clipboard to make file transfer work correctly.
The PR also unifies list filtering into a single functions instead of
having two different functions.

The current server side channel handling of AUDIO_INPUT is currently
very constrained:
- Server implementations cannot measure the clients uplink, since the
Incoming Data PDU is currently unhandled and FreeRDPs DSP handling
delays the callback call of ReceiveSamples
- Servers currently cannot prefer a different protocol version
- Servers currently cannot change the used format
To solve these issues without running into the risk that some
simplifications constraint certain API usage, rework the current channel
handling to be very close to the documentation.
This means, that all documented API calls can be made by server
implementations and all documented PDUs, that the server side is
expected to receive are just parsed inside FreeRDP and then forwarded to
the API implementation.
Some PDUs, like the Activate Device Request only contain the header.
As a result, the size of the rest of the PDU is 0.
The assertion for the PDU size in device_server_packet_new only
considers the size of the body of the PDU.
When that value is 0, the assertion is hit and the server implementation
crashes.
To fix this issue, simply remove this assertion. Since the allocation
size is always at least the header size, there won't ever be an attempt
to create a stream with a size of 0.
The old implementation used `Stream_GetLength` to obtain the amount of
data to send. However some PDUs (i.e. CLIPRDR_FILECONTENTS_REQUEST) are
overallocated as they contain optional data (clipDataId in this case).
We now use the position to determine the actual data written to the PDU
instead of the amount of bytes allocated, avoid sending garbage data to
the client.
* Add callbacks for all messages exchanged between client and server
to allow server implementations to intercept them.
* Unify logging
* Add device tracking
due to the nature of the sound channel there are multiple listeners
waiting for the server to open the channel and most of them are called
by the server. Only open the channel once.
* Ensure DeleteSurface is called before CreateSurface: Under certain
conditions it is possible that there already exists a surface with the
same id as the new CreateSurface PDU. Delete the already existing
instance in that case before creating a new one.
* Simplify surface cleanup on shutdown: Use HashTable_Foreach
* Use new ConvertUtf8ToWChar, ConvertUtf8NToWChar,
ConvertUtf8ToWCharAlloc and ConvertUtf8NToWCharAlloc
* Use new ConvertWCharToUtf8, ConvertWCharNToUtf8,
ConvertWCharToUtf8Alloc and ConvertWCharNToUtf8Alloc
* Use new Stream UTF16 to/from UTF8 read/write functions
* Use new settings UTF16 to/from UTF8 read/write functions
CreateFile/GetFileInformationByHandle will fail if used with just a
drive letter i.e. C:/.
This PR fixes that case by using GetFileAttributesExW as a fallback in
case CreateFileW fails.
* Fix length checks in parallel driver
The length requested was not checked against the length read from
the port.
* Fixed missing length check in video channel
Data received in video redirection channel was not checked for
proper length.
* Fixed video presentation reference counter
Video channel presentation reference counter was not updated with
Video_Frame_new. A failing H264 decoding step could trigger a reference
decrement and the presentation was freed by accident.
Also clean up the increment and decrement of presentation

tsmf_ffmpeg_init_stream did not abort if the video format ExtraDataSize
was not sufficiently large to satisfy expectations.
* Fixed missing input data length check
tsmf_ifman_exchange_capability_request did not check if the input
data stream actually contained the amount of bytes requested to
copy.

This patch does various cleanups in the client dynamic channel. The main
goal of the cleanup was to add the sending of Close messages to the server
when a channel is locally closed. The refcounter is there to ensures that
the DVC_CHANNEL is not freed while some pieces of code are still holding a
reference on it.
I did some tests by using a custom server-side echo channel at
https://github.com/hardening/echoChannel, it allows to send a given amount of
packets and then close (to test server-side initiated closes). It compiles
with mingw (so under linux) and so it can be easily deployed (no deps).
* winpr: add lock operation on HashTables
* drdynvc: change the listeners array for a hashtable and other micro cleanups
* logonInfo: drop warning that is shown at every connection
Let's avoid this log, we can't do anything if at Microsoft they don't respect
their own specs.
* rdpei: fix terminate of rdpei
* drdynvc: implement the channel list with a hashtable by channelId
The same code is copied in all dynamic channels to create a plugin, have a listener,
and manage the channel lifecycle. This patch does a mutualization effort so that channels
only have to code things that are specific to them.
pulse/alsa/oss do not reliably work with ALAW/ULAW codecs with all
hardware available.
Since these formats are poor quality anyway, deactivate them for
audin channel.
Most dynamic channels share the same copied and pasted code for the XXX_CHANNEL_CALLBACK
and XXX_LISTENER_CALLBACK types. This patch introduce GENERIC_CHANNEL_CALLBACK and
GENERIC_LISTENER_CALLBACK that fits for most channels and discard custom type definitions.
The current server sided channel handling of RDPSND/AUDIO_PLAYBACK_DVC
is currently very constrained.
So, solve this. This means:
- Add the missing Training/Training Confirm PDUs
- Stop overriding the average bytes per second values, when submitting
the audio formats, as this currently makes the usage of codecs
impossible
- Add a way to send the server formats manually again, to be able to
restart the protocol after a Close PDU was sent
- Add a way to send already encoded audio data to let server
implementations to take care of the encoding process and to set
custom audio timestamps for the Video Optimized Remoting channel
- Add public attributes to let server implementations know the initial
volume and pitch values
- Add public attribute to let server implementations know the quality
mode setting
Currently, all FreeRDP-based clients don't send any WaveConfirm PDUs
for received samples, when using a dynamic channel for audio output
redirection.
[MS-RDPEA] 2.2.3.8 Wave Confirm PDU mentions, that a WaveConfirm PDU
MUST be sent, when a WaveInfo PDU + Wave PDU, or Wave2 PDU is received
and when the audio data sample is emitted to completion by the client.
The first WaveConfirm PDU is used by the server to determine the
network latency and the second WaveConfirm PDU is used by the server to
determine the render latency.
So, fix the current behaviour, where FreeRDP currently does not send
any WaveConfirm PDU, when using the dynamic channel, or only sends one
WaveConfirm PDU for the sample.
For the first WaveConfirm PDU, use the same timestamp, that was
included in the first WaveInfo/Wave2 PDU.
For the second WaveConfirm PDU, add the render latency on top of the
arrival timestamp.
_align_XXX functions aren't widely available depending on the C runtime. That causes
problems with mingw where we can easily have some runtime mixes (which lead to mysterious
segfaults most of the time). This patch introduce winpr_aligned_XXX functions that will
either use the function available, or use an emulation layer.
