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
* Fixed tsmf ffmpeg context extra data size checks
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.
* Fixed TSMF tsmf_ffmpeg_set_format length checks
ExtraDataSize of format was not checked for expected minimum length
* Fixed TSMF tsmf_read_format_type length checks
ExtraDataSize of format was not checked for expected minimum
length

ExtraDataSize of format was not checked for expected minimum
length

* Added WINPR_LOCAL for test builds
This macro exports internal functions in case of a unit test build
This way unit tests can access these without other workarounds.
* Fixed typo in function name is_dos_driver
* Cleaned up FindFirstFileW call
Use a wrapper function to convert to unicode and call the function
* Cleaned up BUILD_TESTING and EXPORT_ALL_SYMBOLS
* EXPORT_ALL_SYMBOLS now does as the name implies and exports all
non static functions/variables from the library.
* BUILD_TESTING now only sets the defines for test code and
activates EXPORT_ALL_SYMBOLS to allow tests to access internal
code
* Fixed windows client warnings
* disable CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS
* printer_win: Retrieve default printer name
* printer_win: Declare the local default printer as default
* printer_cups: Retrieve default printer name
* printer_cups: Declare the local default printer as default
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

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.

Building client channels out of tree does not work reliable as the
dependencies can not be easily split. (exceptions may be simple ones
as echo channel)
It does complicate the build system and code though, so remove this
for maintainability reasons.
The server sided handling of the display control channel currently
treats the physical monitor size values as obligatory values.
When the physical monitor size is invalid according to the
documentation, it is supposed to be ignored.
However, this is currently not done, leading to an abort of the display
control channel handling, when using Remmina, as Remmina does not submit
physical-monitor- widths and -heights.
Fix this issue by sanitizing the physical monitor size values, instead
of handling them as obligatory values, where both the physical with and
the physical height must be constrained to the values in the
documentation.
{channels/tsmf/client/ffmpeg/tsmf,libfreerdp/codec/dsp}_ffmpeg.c:
Guard calls to `avcodec_register_all()` against use beyond
`AV_VERSION_INT(58, 10, 100)`, where upstream ffmpeg made it obsolete.

(Stream_SetBuffer, Stream_SetPointer, Stream_SetCapacity)
* Ensure length/capacity functions never return a value larger
than the actual length/capacity
When the server supports the protocol version RDPINPUT_PROTOCOL_V300,
the additional supportedFeatures field will be present.
The pduLength in the RDPINPUT_HEADER should, however, reflect this.
So, fix this error by writing the correct PDU length when the
supportedFeatures field is present.
* Split out proxy headers and moved to public API to allow external
modules to be built.

channels work.
* Extended module API to hook more events, improved module samples
* Cleaned up proxy code, removed global static variables used,
added WINPR_ASSERT
RDPSND channel is special, as it has many names.
(e.g. static channel, dynamic channel and UDP one.
Use RDPSND_CHANNEL_NAME to identify the module name instad of
RDPSND_DVC_CHANNEL_NAME
If -DBUILTIN_CHANNELS=OFF is supplied to cmake, auxiliary channel modules
are built as plugins, that are loaded from $LIBDIR/freerdp as shared libs.
This patch fixes the linkage of these plugins by taking inter-channel dependencies
of this separation into account. If BUILTIN_CHANNELS=ON, these channel modules
are linked directly into the main modules. Therefore, the linking of the plugins
is conditioned accordingly.
