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

When using software gdi (/gdi:sw) the rdp update PDU callback
gdi_palette_update() is used which writes the new colors to
the rdpContext's gdi->palette buffer.
The X11 functions however access xfc->palette which gets only
updated by xf_gdi_palette_update() which is the callback if
/gdi:hw is used.
This commit changes xfc->palette to a pointer which points to
xfc's private buffer with /gdi:hw or to the gdi->palette if
software gdi is used.
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
The window width/height variables and in turn SmartSizingWidth/Height
get automatically updated in th the configure notify event handler.
If the window is created initially the values don't differ from the
event values and therefore SmartSizing was not applied until the
window was resized.
- make smart-sizing work again which was killed in previous commits
- removed several unnecessary/ugly workarounds
- miscellaneous small fixes
- new feature: restore previous window position when toggling out of
fullscreen mode
- new feature: if /f is specified in combination with /smart-sizing:WxH
we run the session in the /smart-sizing dimensions scaled to full screen
Since several contributers in the past repeatedly made the error
to treat xfc->width and xfc->height as equal with the x11 window
width and heigth I've renamed these variables to sessionWidth and
sessionHeight.
Small cleanup of passing around decorations flag.
Limit PercentScreen to single monitor vs. entire desktop. IMO - this is better behavior in a multimonitor environment.
Handle fullscreen windows better:
1. Ensure that size hints are set to allow resizing before setting a window to fullscreen as some window managers do not behave properly.
2. Handle fullscreen toggles without destroying and recreating window.
3. Use NET_WM_STATE_FULLSCREEN Extended Window Manager Hint for fullscreen functionality
4. Use the NET_WM_FULLSCREEN_MONITORS Extended Window Manager Hint when appropriate
5. When a single monitor fullscreen is requested - use the current monitor(as determined from mouse location)
6. Handle cases where there is no local monitor at coordinate 0,0. The Windows server expect there to be a monitor at this location, so we maintain offset if necessary between our local primary monitor and the server side primary monitor located at 0,0.
Note: /gdi:sw was working fine, this commit fixes /gdi:hw
* calculate color channel shifts based on X11 visual color masks
* fast path to skip conversion if visual color masks equal rdp color masks
* successfully tested 8/15/16/24/32 bpp rdp sessions on 16/24/32 bpp visuals
In case of server side initiated desktop resize it could happen that the
client was "scaling" even if smart-sizing was disabled. The reason for
this was that the "scaled" width and height was set when the X Configure
event arrived but not in xf_desktop_resize.
* fixed crash on server-initiated desktop resize and fullscreen toggle with /gdi:sw
* implemented desktop resize for /gdi:sw
* check for availibility of XRender extension and show error messages if a setting would require it
* fixed compile error if xrender devel packages are missing
* fixed bug with server-initiated desktop resize in fullscreen mode
* client/X11/xf_client.c (xf_pre_connect): Set the field `colormap' of
`struct xfContext' to the default colormap.
* client/X11/xfreerdp.h (xf_gdi_get_color): Declare new external function.
* client/X11/xf_gdi.c (xf_gdi_get_color): Define new external function.
Use xf_gdi_get_color() to get the appropriate X color index from the GDI
color representation.
* client/X11/xf_graphics.c: Likewise.
