It seems like WaitFor[Single|Multiple]Object calls aren't reliable on pipes, especially
on the pipe opened for childSession access. The object can be marked as signaled even if
no data is available, making the connection laggy and unresponsive (nearly unusable in some
cases).
This patch works around that by using ReadFileEx() with overlapped instead of simple
ReadFile() and use asynchronous reads.
freerdp_peer->Disconnect calls BIO_free which then calls close on the
underlying file descriptor.
Then when freerdp_peer_free is called, the file descriptor is closed
again.
This is problematic if the file descriptor is recycled in between:
thread 1: freerdp_peer_new(42);
thread 1: freerdp_peer->Disconnect() closes 42
thread 2: opens a file with fd 42
thread 1: freerdp_peer_free closes 42
thread 2: uses closed file descriptor 42
The ArrayList, HashTable, ... New functions require
void* (*fkt)(const void* ptr) type functions. Provide a generic wrapper
for CHAR and WCHAR strdup to eliminate warnings. Also export a
corresponding free function to avoid issues with runtime
differences.
Sometimes the RPC PDUs have unprocessed data (padding bytes) at their
end. In that case do not fail but just log a warning with the correct
amount of remaining bytes.
The RDS AAD Auth PDUs have no packet headers to indicate length.
Instead, these packets are zero-terminated strings. Somehow, Windows
accepts Authentication Request PDUs without a terminating null byte
during regular connections, but not through WVD websocket gateways.
If the peer state machine is in state
CONNECTION_STATE_CAPABILITIES_EXCHANGE_MONITOR_LAYOUT properly check for
available data. If a PDU was received in this state it is an out of
sequence PDU (that might happen during deactivation/reactivation) and
must be parsed.
* FreeRDP_WTSVirtualChannelWrite might be called from different threads,
so lock the function execution to keep split packets in order
* unify DVC and SVC channel creation/deletion to avoid duplicate code
The client must handle graphics updates in EndPaint.
If we already reached BeginPaint again reset the invalidated regions
as they are already processed and start anew. Fixes#9672
The previous code was assuming that the host name used for doing AAD was
ServerHostname parameter. But when you connect directly to Azure hosts you most
likely connect by IP and use short name for the AAD host, so you need to be able
to give ServerHostname=<IP of host> and AadServerHostname=<shortname>.
