This patch make it possible to limit the time that is passed when we call
XXX_check_fds functions. This should smooth the treatment between handling inputs
and handling incoming bitmap updates.
The default maximum time is set to 100 ms.
CMake 2.8 does not support default visibility on windows.
To allow building tests add the FREERDP_LOCAL define for each
function that is internal to FreeRDP.
When build with testing these functions are exported and available
for use by tests.
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.
Not use sizeof on packet memory structure for stream length check/estimating and use number directly.
Most of the packet size could be obviously calculated/verified from code and comments in same function.
Macro is defined for those were referenced multiple times.
1. Fix style for channels/rdpgfx/server/rdpgfx_main.c according to scripts/format_code.sh
2. Refactor and introduce APIs to allow rdpgfx server channel running in existing thread (similar to rdpsnd)
1. Fix stream leak in rdpgfx
2. Make src data const in zgfx. Harden zgfx to be independent to byte order
3. Fix written bytes return value in channel write
4. Add check for return value in shadow_client.c
5. Add gfx callback to send surface command with frame marker pdu.
6. Check remain length for recv subroutine
7. Fix compile errors
This patch adds some callbacks so that the client can have access to the informations
stored in this packet. Server-side implementation is also there, so that a server
can send these informations to the client.
Certificates can now be accepted temporarily.
The callbacks for certificate validation have been
modified to extend the information presented to the user.
Sometime it's possible that your server application doesn't have access to files
(when running in a very restricted environment for example). This patch allows
to ship the private key and certificate as a string.

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.
It will be completely possible to implement subsystem with only include/freerdp/server/shadow.h and libfreerdp-shadow.
Details as following:
1. Exported surface structure as subsystem implementations deeply depend on it to send image update
2. Export capture APIs. They are actually indepent APIs to help compare and calculate image difference.
3. Introduce API to trigger client frame update. Conceal details in subsystem->updateEvent
4. Pass client to client callbacks. Subsystem implementation may need to know 'which client' send the interaction event as well as the authentication request.
Add this support in callback definition before anyone really use shadow framework APIs to implement a custom subsystem.
Also added callback for client capability exchange
5. Remove X11_ShadowSubsystem Mac_ShadowSubsystem Win_ShadowSubsystem from libfreerdp-shadow.
Discard FREERDP_API mark on ShadowSubsystemEntry functions and make them be compiled together with shadow.c in CMakeLists.txt.
This is required from PR #2751.
Now subsystem implementations and shadow.c could be regarded as an example for shadow framework.
The Miscellaneous section is chosen because choosing not to map the
buttons is not a property of the input system, but rather an ad-hoc
setting to be applied to this session.
In case the old behaviour of not reverse-mapping the mouse buttons is
desirable, a command-line option is added to disable the mapping. This
option is made experimental for the time being.
The default is to do the reverse mapping, as this is the intuitive
behaviour (the mouse then works as it would on the console).
Horizontal mouse wheel input capabilities are now checked
and if available mouse buttons 6 and 7 are mapped to the
horizontal wheel for the X11 client.
build-config.h should contain configure/compile time settings that are
relevant for projects that use FreeRDP.
For example the compiled in plugin search paths.
The rdpContext gets an event which will
get set if an error occoured in a channel.
If a thread or a void callback has to report an
error it will get signaled by this system.
Detail fixes:
1. Add resize support in shadow framework layer
2. Enhance X11 implementation to detect desktop resolution change
3. Fix the subRect feature.
It seems not completely finished and it looks incompatible in different source code.
Fix it to be consistent in all source code as following:
a. The subRect is only awared in framework layer, subsystem implementation should not be aware of it. It only take effect at shadow_client and corresponding shadow_input.
b. The screen and surface should only represent a monitor screen. They don't need to consider subRect feature.
4. A lobby should be alternative image shown to client when the client is not 'mayView'.
We don't need to have seperate lobby for each client, move it into server structure as 'another surface'
5. Fix display handle leak in enum monitor of X11
6. Suppress BadMatch Error while capturing the image
Original pointer alpha update message is too specific for x11 implementation.
It doesn't allow pointer alpha mask with both 'xor' color and 'and' mask, e.g.: the 'edit' pointer in windows text box.
1. Move shadow_client_convert_alpha_pointer_data to x11 implementation as it is specific for x11.
2. Update message definition to be more generic: to accept 'xor/and' mask directly.
Implementation of subsystem can implement its own way to convert pointer mask data.
3. Fixed fault handling to free the resource allocated.
This patch adds checks for the sound channel and plugins:
* checks for protocol bytes;
* checks for malloc/calloc;
* be more strict when interacting with sound plugin
1. Export fps related API so that subsystem implementation no longer need to know about details in encoder structure.
2. Discard frameList dictionary.
The 'value' in this dictionary is never used and not properly free'ed when client is disconnected.
The dictionary was used to calculate 'inflight' frame count. Once an ACK is received from client, an item in the dictionary is removed.
We then calculate 'inflight' frame by the count of the items in the dictionary.
However, some rdp clients (win7 mstsc) skips frame ACK if it is inactive, ACK of some frame would actually never arrive.
We actually don't need the dictionary. We only need to record the latest acknowledged frame id, and the difference between last sent frame id is the inflight frame count.
3. Minor fix in default fps calculation. encoder->frameAck is wrongly used as integer while it's actually bool flag.
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
1. Introduce message queue in shadow client. No longer use subsytem->MsgPipe->out to deliver message to clients.
We used to use subsytem->MsgPipe->out for messages which need to be sent to client. But it's not correct. Only one client would get the message if multiple client exists
This problem make the fix in PR #2643 incomplete.
Introduced reference count based solution to release resource taken by the message.
Also added APIs for client message delivery.
Also fixed msg pipe in subsystem to clean resource when destroyed.
2. Discard unused StopEvent in client. We actually use quit message instead.
3. Enhance disposal of channels.
Free context for remdesk and encomsp channels. The original fix only stop the threads, but doesn't release resource.
Dispose channels earlier. The channels are built on client->vcm. Disposing channels after client->vcm is closed cause unknown behavior.
Original fix is #2644
4. Start to add audio support.
If no entry for the <host> <port> combination
was found in the v2 file and there is a legacy file
check if a matching <host> entry can be found.
In case there is a matching entry and the <fingerprint>
also matches, create a new entry in the v2 file using the
current port.
