With the location channel, an RDP server can redirect the location of
the user from the client side to the server side.
The PDUs are almost the same as in the documentation, except for the
encoded types, these ones are here already parsed.
Optional values are accessed via pointers. If the pointer of a value is
NULL, then that value was not supplied by the client side.
Some virtual channels, like the location channel use encoded types to
lower the bandwidth usage.
Add common helper functions, so that each virtual channel doesn't have
to reimplement the parser functions again and again.
Under windows you can connect to a child session by requesting a named pipe to
the local server, and then do some RDP on this named pipe.
The protocol is like for /vmconnect with CredSSP, then Nego and then the "normal"
workflow for a connection. For CredSSP we force the usage of NTLM for the Negociate
SSPI, and the credentials are empty.
This patch moves the ARM configuration before starting the connection process, so
that we can do some provisioning of the FreeRDP settings with the items retrieved
from Azure.
Most notably that allows us to connect directly using RDSTLS security.
Some windows APIs do put \r\n every 64 characters of the output of a
base64 encoded blob. The extended version of crypto_base64_encode allows
to do the same.
C requires prototypes or compilers will complain about them missing. Our
library entry points do not have such, therefore add the macro
FREERDP_ENTRY_POINT which declares the function prototype automatically
before the function.
All clients can implement their own callbacks for
certificate/credential/smartcard/... but there is a common (default)
implementation for all clients.
with the new setting FreeRDP_UseCommonStdioCallbacks it is now possible
to force these over the client implementation provided ones
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.
This PR creates a new /gateway:type:arm transport.
It depends on CJSON
The arm transport is not a transport by itself but is responsible
for getting the websocket endpoint from a configuration url derived from
the configured gateway host in the rdpw file or cmdline
