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.
Certificates can now be accepted temporarily.
The callbacks for certificate validation have been
modified to extend the information presented to the user.
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).
If XInput extension is available, then find the (first) pointer device
and use the button mapping of that one. If there are more than one
pointer devices, they could have different button mappings, but it is
not clear how this should be communicated to the RDP server.
If XInput is not available, attempt to fallback to the old global
mapping. (This mapping exists, but is not correct if there actually
is an XInput extension loaded, as it is then not used).
RDP expects to receive an indicator of the physical mouse button that
was pressed on the client, whereas X11 deliver a value for which
logical mouse button that was pressed.
This patch introduces a (reverse) mapping from logical mouse buttons to
physical mouse buttons, so that the RDP server can do correct mapping
for the event on its end.
However, no actual mapping is done here; this patch just introduces the
framework to do so. Thus, there should be no behavioural change from
this patch alone.
There is an implicit assumption that only the first three buttons are
mapped to eachother. Enabling more a general mapping would require
extensive changes to the event handling as fourth logical button and
up is used for special functionality such as wheel.
- xf_cliprdr_is_self_owned() lied if multiple xfreerdp instances were
running.
- fixed a few unchecked callocs
- added/modified and handled some return values in compliance with
the new hardened channel api
1. Remove all uses of "localWindowOffsetCorr" variables, they added an extra layer of complexity and they are not actually needed to handle coordination of window position/size between
the local coordinate system and the remote one. This logic was causing issues in the case where the window was moved off the left side of the screen.
2. Update the xf_setWindowVisibilityRects function to offset the visibility rects as necessary when the window is hanging off the left side of the screen.
3. Stop sending mouse events when doing keyboard moves/sizes(as desired), and stop sending two mouse events for non-keyboard moves/sizes
4. Move location of new UTF8_STRING variable from previous commit
5. Refresh window and window shape for any window position/size updates, this helps keep the local and server windows in sync and works around some race conditions
The regions used to store and calculate the invalidRegion are exclusive
of the bottom and right edges, not inclusive.
Fixes "mouse droppings" in mspaint.exe when moving the mouse leftwards
across the canvas.
1. Make use of freerdp_set_last_error to set authentication failure without the helper functions
2. Rename ssl callback function
3. Break out AuthenticationOnly exit handling from bad connect handling
Channels like EGFX need resources like the main window in order to
work correctly. Before the window, GDI,.. is freed it needs to be
ensured that all channels are stopped properly to prevent them to access
already freed resources. Disconnecting the channels first fixed a
possible race condition/SEGFAULT that could occur with remote initiated
disconnects.
winsock.h pulls in a lot of defines and dependencies that are not
required and partially unwanted in winpr's core (for parts that are not
related to network). In order to get rid of this dependency and have an
independent defines for extended winpr functions the WINPR_FD_* defines
are used internally (and for exposed functions). Where required, like in
WSAEventSelect, the FD_* is mapped to WINPR_FD_*.
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
