[client/Windows/wf_cliprdr.c:2556] -> [client/Windows/wf_cliprdr.c:2561]: (warning) Identical condition '!clipboard', second condition is always false
Added a library internal function freerdp_settings_set_default_order_support
which initializes the OrderSupport array of settings.
Now clients no longer need to set this up on their own, if they
do not implement their own hardware accelerated order processing.
With #4950 client side pointer implementation was made optional.
This addresses an issue that each client had to call
pointer_cache_register_callbacks on its own.
The async transport option is broken by design.
If used the main loop is called from the transport thread and the
main thread of the application.
Unless the transport layer is refactored to just work on queues
(input and output) this option will never work, therefore remove it.
the objective is that only the updated region(s) are refreshed instead of the whole screen
it's not much a problem for normal FreeRDP usage but becomes a serious issue if the display is processed, forwarded and rendered remotely, as done by web gateways such as Guacamole, FreeRDP-WebConnect and Myrtille (I'm the author of the latter)

- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments
- use inttypes defines where appropriate
Global static variables do not work, if more than one instance
of an RDP client is running in the same process space.
Removed the varaibles where possible and replaced them with
thread local storage where necessary.
libxfreerdp-client doesn't necessarily provide a stable interface
therefore it isn't built and installed anymore per default.
To archive the same behavior as before this change -
libxfreerdp-client.so built and a library version set - use
-DWITH_CLIENT_INTERFACE=ON -DCLIENT_INTERFACE_SHARED=ON
when running cmake.
This also fixes the build on windows without WITH_CLIENT_INTERFACE
enabled.
- Added missing ConvertFromUnicode checks
- If ConvertToUnicode allocates memory, guarantee the null termination
similar to ConvertFromUnicode's implementation
- Fixed some TestUnicodeConversion.c CTest return values
- Added some CTests for ConvertFromUnicode and ConvertToUnicode
- Misc code and protocol hardening fixes in the surrounding code regions
that have been touched
Certificates can now be accepted temporarily.
The callbacks for certificate validation have been
modified to extend the information presented to the user.
With this commit the "exported" components (usable with pkg-config and
cmake find module package)
* winpr - winpr library and headers
* freerdp - core library and headers
* freerdp-client - client specific library
* freerdp-server - server specific library
* rdtk - rdtk headers and library
To allow the installation of multiple different version (different major
number) the include files were moved into the respective sub folder:
freerdp -> freerdp{MAJOR}/freerdp (currently freerdp2/freerdp/)
winpr -> winpr{MAJOR}/winpr (currently winrp1/winpr/)
rdtk -> rdpk{MAJOR}/rdtk (currently rdtk0/rdtk/
The generated pkg-config and cmake find modules now also include the major
version number. Currently the following pkg-config are generated and
installed.
* winpr1
* freerdp2
* freerdp-server2
* freerdp-client2
* rdtk0
As cmake is able to handle multiple versions out of the box the
following can be used to find a specific module:
find_package(WinPR)
find_package(FreeRDP)
find_package(FreeRDP-Server)
find_package(FreeRDP-Client)
find_package(RdTk)
As cmake doesn't automatically resolve dependencies for packages it is
necessary to manually include the requirements. For example if
FreeRDP-Client is required WinPR and FreeRDP need to be included
(find_package) as well.
This commit also fixes the installation when STATIC_CHANNELS are built.
WITH STATIC_CHANNELS all channels are linked into libfreerdp-client, for
this all channels are generated as linker archive and linked together in
the final step. Before the intermediate linker archives were, although
not required and useful, installed. Same applies for server side
channels.
This patch contains:
* checks for malloc return value + treat callers;
* modified malloc() + ZeroMemory() to calloc();
* misc fixes of micro errors seen during the code audit:
** some invalid checks in gcc.c, also there were some possible
integer overflow. This is interesting because at the end the data are parsed
and freed directly, so it's a vulnerability in some kind of dead code (at least
useless);
** fixed usage of GetComputerNameExA with just one call, when 2 were used
in misc places. According to MSDN GetComputerNameA() is supposed to return
an error when called with NULL;
** there were a bug in the command line parsing of shadow;
** in freerdp_dynamic_channel_collection_add() the size of array was multiplied
by 4 instead of 2 on resize
- HRESULT was unsigned which means that until now all usages of the
SUCCEDED(hr) and FAILED(hr) macros never detected any errors
- Also fixed the (unused) SCODE typedef
- Added new ctest TestTypes
1)
Added missing checks for CreateEvent which also required the
following related changes:
- changed freerdp_context_new API to BOOL
- changed freerdp_peer_context_new API to BOOL
- changed pRdpClientNew callback to BOOL
- changed pContextNew callback to BOOL
- changed psPeerAccepted callback to BOOL
- changed psPeerContextNew callback to BOOL
2)
Fixed lots of missing alloc and error checks in the
changed code's neighbourhood.
3)
Check freerdp_client_codecs_prepare result to avoid segfaults
caused by using non-initialized codecs.
4)
Fixed deadlocks in x11 caused by missing xf_unlock_x11() calls
in some error handlers
5)
Some fixes in thread pool:
- DEFAULT_POOL assignment did not match TP_POOL definition
- don't free the pool pointer if it points to the static DEFAULT_POOL
- added error handling and cleanup in InitializeThreadpool
- removed some unneeded null checks for free()
- fixed a memory leak in shadow_client
- removed rfx_compose_message_header from API
Changed the following functions to BOOL, check the result
where they are called and handle failures:
- rfx_compose_message
- rfx_compose_message_header
- rfx_write_tile
- rfx_write_message_tileset
- rfx_write_message_frame_begin
- rfx_write_message_region
- rfx_write_message_frame_end
- rfx_write_message
rfx_process_message:
- check memory allocation failures
- verify protocol-conform order of data messages to prevents memory
leaks caused by repeated allocations
- verify that header messages were parsed/received before the
data messages
- treat unknown rlgr mode as error
- fixed/added error handling
- fixed all callers to check/handle result
rfx_encode_message:
- fixed incorrect usage of realloc
- missing malloc check
- missing check of CreateThreadpoolWork
- correct cleanup on failure (threadpool, memory)
- check rfx_encode_message result
rfx_encode_messages:
- check rfx_split_message result
- correct cleanup on failure
- prevent memory leak on failure
rfx_write_message_context:
- fixed invalid channelId value (must be 0xFF for WBT_CONTEXT)
rfx_process_message_codec_versions:
- fixed invalid read size of codec_version (it is 16bit)
rfx_process_message_channels:
- verify protocol conform channelId value
rfx_process_message_region:
- replaced invalid reallocs with malloc
- read and verify regionType and numTileSets from stream
rfx_process_message_tileset:
- check allocation results
- fixed incorrect usages of realloc
setupWorkers:
- fixed incorrect usages of realloc
rfx_split_message:
- removed dead code
- missing malloc check
rfx_compose_message:
- fixed a memory leak
- check/handle rfx_encode_message result
The input->FocusInEvent callback implementations (normal and fast-path) have
always sent the mouse position even if the pointer was outside of the freerdp
client area. In addition xfreerdp used the wrong pointer coordinates which
were relative to the root window instead of its own.
On focus-in the pointer position must only be sent if the pointer is
currently within the program's client area. However, the clients had no way
to pass that information to input->FocusInEvent which required an API change.
- removed mouse pointer x, y parameters from input interface's FocusInEvent
- clients are responsible to call input->MouseEvent on focus-in if necessary
- fixed xfreerdp and wfreerdp accordingly
"libfreerdp" consisted of multiple (small) single libraries. If the cmake
option MONOLITHIC was used only one library was build combining all of
the libfreerdp-* libraries.
The only exceptions to this are libfreerdp-server and libfreerdp-client these
are build as separate libraries.
This commit obsoltes non-monolithic builds and makes monolithic builds
the default. The cmake option MONOLITHIC is also removed.
