The AAD and AVD authentication mechanisms both need an OAuth2 token.
They only differ in the provided arguments, so unify the callbacks into
a single one with variable argument lists.
- Move responsibility for obtaining access tokens to clients
- Add function for getting access tokens for AVD
- Get correct server hostname during AVD setup
- Add utility function for doing http requests
The purpose of clipboard data locking is to make the other peer
retaining the current file list until a pending paste operation is done,
even though the clipboard selection changed.
As it may be difficult to determine, when a lock is needed, imitate the
same behaviour as mstsc:
When the server side supports clipboard data locking, always attempt to
lock the file list on the server regardless of what is advertised in a
FormatList PDU.
The Lock Clipboard Data PDU can even be already sent, before the
Format List Response PDU is sent.
This is also what mstsc, does: First, lock the new (potential) file
list, then unlock the file list, when the pending paste operation is
done.
So, rework the current clipboard implementation in that direction.
Since the implementation for timeouts for old file lists is a bit hard,
for now always force unlock pending locks, when the selection changes.
However, timeouts for old file lists can still be added in the future.
The reworked clipboard handling is done with the help of three hash
tables:
1. The inode table: This hash table manages all inodes for each file.
The keys in this table are the inodes themselves, while the values
the files and directories and their attributes (file size, last write
time, etc.).
2. The clipdata table: This table manages the locks for each file list.
The keys in this table represent the clip data id and the values the
clip data entries, which have a reference to the clip data dir, a
directory containing the whole selection, and some helper attributes,
like the clip data id itself.
3. The request table: Every file size or file range request is managed
here. When a FileContentsRequest is made, its stream id with the
respective details are added to this table. When a response is
received, these details can then be easily looked up here.
Reinitialize xinput input event masks to get events from newly plugged
devices after setup. We utilize XI_DeviceChanged and XI_HierarchyChanged
event types to handle device changes.
Optionally build the SDL client with Qt WebEngine to create a popup
browser for authentication to AAD. Also change the URL output on the
command line to use the "nativeclient" redirect for easier copy/pasting
of the authorization code.
When receiving a file list, xfreerdp3 rebuilds the content of the FUSE
filesystem.
Since fetching uri-lists can happen during a paste action too, xfreerdp3
caches the content of the last fetched mime type.
However, uri-lists exists in different variations, e.g. nautilus uses a
different mime type, than gnome-terminal does.
Furthermore, FormatLists can also contain other formats in addition to
file lists.
Fetching those contents during a paste operation leads to IO errors in
the paste operation.
In order to fix those errors, cache every mimetype in two hash tables:
One for the raw (unconverted) data, and one for the converted data.
When a content request is received, xfreerdp3 can with the already
cached converted data, directly serve the data.
If the content is not available as cached data, but its source data was
already fetched, use that source data to create the converted data.
Then serve the converted data.
Only if no cached converted data or cached raw data is available, issue
a new FormatDataRequest.
Format lists can contain multiple clipboard formats. When the data for
one is requested, xfreerdp caches it.
When the data for a different format in the same format lists is
requested, xfreerdp cannot use the already cached data, since that data
refers to a different format.
As a result, xfreerdp needs to ask for the data of the now requested
format.
However, this is currently not the case. xfreerdp will just provide the
data of the first request after receiving the last format list.
In order to fix this situation, also save the format id of the last
requested format.
If the format id of the cached data matches the one of the current
request, serve the data from the cached data.
Otherwise, issue a new FormatDataRequest.
Commit 6492a00959 introduced a way to
relieve the filename restriction, which ensured that file lists
containing files with names, that have characters, which are not allowed
on MS Windows.
This relief handling kicked in, when xfreerdp did not connect to MS
Windows RDS.
Commit d521c7fa74 got rid of any
wClipboardDelegate occurrence in xf_cliprdr.c, which also got rid of the
filename restriction relieve handling.
However, the relief handling was not added back, so do it now.
to debug bug reports occuring only with certain setups wrap the function
call with a logging edition so we have the arguments available in the
log for debugging.
most protocol internal caches do not need to be exposed. this reduces
the public API and allows us to more easily improve/change this during a
release cycle
To have more fine granied control add a new callback.
Now you have the following callback pairs:
* PreConnect <--> PostFinalDisconnect
* PostConnect <--> PostDisconnect
* Use new ConvertUtf8ToWChar, ConvertUtf8NToWChar,
ConvertUtf8ToWCharAlloc and ConvertUtf8NToWCharAlloc
* Use new ConvertWCharToUtf8, ConvertWCharNToUtf8,
ConvertWCharToUtf8Alloc and ConvertWCharNToUtf8Alloc
* Use new Stream UTF16 to/from UTF8 read/write functions
* Use new settings UTF16 to/from UTF8 read/write functions
* Adds a new callback and settings in gdiGfxSurface to allow updating
a window directly from surface bitmap data
* Adds new BOOL in gdiGfxSurface windowMapped and
handleInUpdateSurfaceArea to control where surface data update is
being handled
If the mouse enters/leaves the window or the window is unmapped in
desktop session mode we can reset the keyboard modifiers state
while in remote app mode these events have different meaning. Be
more strict in the latter case and only reset on focus out
* Fixed format strings to match arguments
Reviewed and replaced all %d specifiers to match proper type
* Added proxy dynamic channel command type to log messages.
* xfreerdp: fix typo in logs
* winpr: file appender, small code cleanup
* shadow-server: add an option for TLS secrets
This allows to dissect connections to the shadow server.
* fix moving a window shrinks it 14x7 when connect to server 2019

Microsoft Windows imposes strict filename restrictions on its platform.
As RDP is developed by Microsoft and the RDS in MS Windows is typically
used as remote desktop server for the RDP protocol, these filename
restrictions are also enforced in WinPR, when copy-pasting files over
the clipboard.
However, in some connections no peer on MS Windows is involved and in
these situations, these filename restrictions are just an annoyance.
With a recent API addition in WinPR, it is now possible to override the
callback, where the filename is checked, whether it is valid.
So, use this new API to relieve the filename restriction, when the
connected remote desktop server is not on MS Windows.
_align_XXX functions aren't widely available depending on the C runtime. That causes
problems with mingw where we can easily have some runtime mixes (which lead to mysterious
segfaults most of the time). This patch introduce winpr_aligned_XXX functions that will
either use the function available, or use an emulation layer.
