After #3097, the java side pass command line argument to JNI for freerdp settings. However there's several issues need to be fixed:
1. The argument /sound should be appended if freerdp is required to play sound at local device
2. The option value for "audio-mode" is not correct.
It should match the definition in client/common/cmdline.c
/* Audio Mode */
define AUDIO_MODE_REDIRECT 0 /* Bring to this computer */
define AUDIO_MODE_PLAY_ON_SERVER 1 /* Leave at remote computer */
define AUDIO_MODE_NONE 2 /* Do not play */
3. Uncomment support for WAVE_FORMAT_PCM in audin. I tested on my android phone and Nokia N1 tablet. It works on both device
* Make sure that numFormats has reasonable value
This will help catching errors like writing -1 as an unsigned number
of formats into the serialized stream, or trying to read the property
after someone else erroneosly messed with it, or other similar mistakes
which would result into reading and then sending garbage to the server.
We read the list xf_cliprdr_get_raw_server_formats() from an X window
property. Properties generally cannot be larger than 4 KB and each
format requires at least 5 bytes (most of them are named, though),
which gives us 512-ish limit on the number of formats we can squeeze
into the property.
However, it's hard to find an application that provides more than
20 formats (I've seen like 15 for MS Office apps), thus I believe
we can safely assume than anything that does not fit into a byte
means that we are reading garbage rather than a good format list.
* Check for the end of stream when reading format names
This also prevents reading garbage and getting segmentation faults
and Valgrind warnings when somebody somewhere sometimes forgets to
put a terminating null character where it belongs.
strnlen() and strndup() functions are provided by POSIX.1-2008
which we can reasonably expect to be available in 2016.
Certificates can now be accepted temporarily.
The callbacks for certificate validation have been
modified to extend the information presented to the user.
Extend winpr and client/common to support a new option "/buildconfig".
When used build the following build specific information is print:
* cmake options
* cflags
* compiler
* target architecture
* cmake build type
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.
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.
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.
The second step of raw transfer is to transfer the format data itself.
This has been already implemented in XFreeRDP before, but several
tweaks are required for it to work correctly.
The idea of raw data transfer is to request for _FREERDP_RAW clipboard
format while putting the actual formatId into _FREERDP_CLIPRDR property
where the requested data is expected to arrive to. Then the clipboard
owner will check for the real formatId and deliver the expected data.
This stays true, but the check is performed in a more straightforward
way, and CF_RAW format (numerically equal to zero) is not considered
an unknown destination format when performing (identity) conversions
with wClipboard. This is not an issue because wClipboard will allow
only identity conversion for CF_RAW, it will fail if something else
is going to be converted into CF_RAW.
The first part of raw transfer sequence is to transfer the format
list of the session A into the session B. Then we will be able to
request/reply with raw data using proper format IDs.
xf_cliprdr_server_format_list() of the session A now exposes the
raw server format list. As soon as the list is received, it is
serialized and put into _FREERDP_CLIPRDR_FORMATS property.
xf_cliprdr_get_requested_targets() of the session B now checks
whether the clipboard owner is a FreeRDP session with enabled
raw transfer capability. If it is, the raw format list is simply
extracted from _FREERDP_CLIPRDR_FORMATS of the clipboard owner.
Otherwise, the format list is populated from the usual TARGETS
clipboard format.
Some time ago there was a property _FREERDP_CLIPRDR_ID which was indended
to indicate that an XFreeRDP window owns a clipboard. This was necessary
for raw transfers. This property was used by xf_cliprdr_is_self_owned()
function. However, raw transfer support was broken and the meaning of
xf_cliprdr_is_self_owned() gradually changed into checking whether
the *current* window owns the clipboard, not just any XFreeRDP window.
Thus _FREERDP_CLIPRDR_ID was removed in a4580923e7 (xfreerdp/clipr:
fix self owned test and hardening).
However, now we are going to fix raw transfers and we need that property.
This patch reintroduces a similar property "_FREERDP_CLIPRDR_RAW" which
indicates that a window is an XFreeRDP window with enabled raw transfer.
It is currently used by xf_cliprdr_server_format_data_request() to
correctly request format data from another XFreeRDP instance via raw
transfer protocol.
This property can be queried from the clipboard owner with the function
xf_cliprdr_is_raw_transfer_available() and can be enabled or disabled
on the current window by xf_cliprdr_set_raw_transfer_enabled().
Disabling raw transfers will be necesary to correctly implement file
transfers in the future. However, currently raw transfers are always
enabled.
xf_cliprdr_send_data_response() is consistently called with NULL
data pointer as a way to report errors, but it was not setting
the msgFlags field accordingly.
Sometimes Windows sends strings with excess null terminating bytes.
For example, when one copies digits from calc.exe. At the same time,
some local applications freak out when they encounter null bytes
(at least LibreOffice is known to be replacing them with '#').
According to the specification of UTF8_STRING format [1], the string
data must not contain any trailing null bytes. So they all should be
trimmed, not only the last one.
Also, if the trailing null byte is not present, the length should not
be adjusted. For example, Firefox is actually sending "HTML Format"
without a null byte while Internet Explorer adds one. The spec for
text/html format [2] says nothing about the teminating null byte, so
we are free to remove it, but at least we should not mistakingly
delete '>' character of "</html>" tag when it is the last character.

Clipboard formats are identified by numerical IDs and literal names.
We can keep using arbitrary defined IDs for local clipboard formats
as we are sure that they have some fixed meaning, but the server can
and will be using its own IDs, which can be different from ours for
the named formats.
Therefore:
1) A correct way to compare a local format to a remote one is
to check the names first, and only then compare their IDs.
(Extra care should be taken to support short format names.)
2) Server IDs cannot be used with wClipboard directly when dealing
with named formats. Format name should be used to extract correct
local ID for the use with Clipboard{Set,Get}Data().
Also, I find the notion of 'alternate' format IDs to be confusing.
We either deal with a fixed ID format (declared in <winpr/user.h>),
or a format that was given an arbitrary fixed ID for local use
(defined in <freerdp/channels/cliprdr.h>), or a remote format
identified by a pair of an ID and a name. Format IDs can be local
and remote, but there are no 'alternates'.
So now:
1) A new function xf_cliprdr_formats_equal() is used to compare
formats correctly in xf_cliprdr_get_server_format_by_atom()
when searching for a server format corresponding to a local
one, and in xf_cliprdr_server_format_list() when constructing
a local TARGETS list from the server format list.
2) Correct local format IDs are used with wClipboard conversions
by xf_cliprdr_process_requested_data() and
xf_cliprdr_server_format_data_response().
3) We refer to formatId and formatName when doing requests,
and srcFormatId and dstFormatId when doing conversions,
instead of using formatId and altFormatId for both purposes.
4) Server format ID and name are used to identify cached clipboard
contents. The name is compared directly as a pointer because it
will be a pointer from the same clipboard->serverFormats array.
Also, the clipboard contents are invalidated when format list
arrives, so xf_cliprdr_server_format_list() now also clears
the format ID and name together with the data.
The functions now have appropriate names which tell what exactly
they are searching for:
xf_cliprdr_get_client_format_by_id()
Get a client-provided format by client-side ID.
xf_cliprdr_get_client_format_by_atom()
Get a client-provided format by client-side format name.
xf_cliprdr_get_server_format_by_atom()
Get a corresponding server format by client-side format name.
The return types of functions have been adjusted accordingly and
correct formats are now used everywhere without mixing them up:
client-side formats are used for client -> server data flow,
while server-side ones are used for server -> client tranfers.
This resolves the issue #1414 as, for some reason, xfreerdp required
server format list to be present to be able to provide its own client
formats. Actually, we need only client format list to provide these.
Also, CF_RAW special case is handled in a more elegant way: it is
assumed to be present in every server format list (which is true).
This patch is needed when wanting to install binaries/libraries to other
locations than data. The linux distro Exherbo installs binaries and
libraries to /usr/<chost>/bin, /usr/<chost>/lib respectively but
manpages should still go in /usr/share/man/ because they are
architecture independent, without this patch they go in
/usr/<chost>/share/man unconditionally.
cmake documentation states:
DATAROOTDIR - read-only architecture-independent data root (share)
So this patch makes it use that so that its configurable.
- fixed wrong calculation of xfc->fullscreenMonitors.[right|bottom]
- only use _NET_WM_FULLSCREEN_MONITORS if at least 2 monitors are involved
- call XMoveWindow before setting the _NET_WM_STATE_FULLSCREEN property
- 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
of existing after only looking at part of the information. For instance, window visibility
rects are part of the message with the new order and were being ignored.
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.
remove duplicate call to XStoreName when setting window title
expand WITH_XEXT #define for rail window rects as extra unecessary work was being done when WITH_XEXT was not defined
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
Don't abort the entire xf_rail_window_common function when the window is
already in the correct location.
To reproduce:
- move an application off the edge of the screen
- resize the window to cause a shape to be set
- move the application window fully on the screen
- resize the application window larger
- note lack of drawing in newly enlarged portion of window
Bug introduced in abf6d4f71e "xfreerdp:
prepare RAIL migration away from libfreerdp-rail" when
xf_rail_MoveWindow was copy-and-pasted into xf_rail_window_common
without noticing that the "return" would omit the rest of the combined
function, not just the portion that was pasted.
Since REGION16 uses unsigned values, when appWindow->x or appWindow->y
is negative, the region will have a very large left or top value.
Avoid this problem by clamping to 0 before casting to an unsigned value.
When connecting to windows 8.1 machines the remote RDP server
implementation sometimes sends invalid H264 data. To avoid client
disconnections ignore the broken updates.
