Currently the proxy's TLS fallback if an NLA connection attempt failed
is broken. There are two issues with the current code that this PR
fixes:
- freerdp_reconnect is used which requires an already established
connection to work correctly. This is not the case since the NLA
connectin attempt failed. This resulted in a seemingly working TLS
connection but i.e. channels where missing/not working.
- The fallback connection attempt just altered the NLA security setting
in the instance's settings. However these settings have been already
modified by the NLA connection attempt so we need to create a copy of
the original connection settings before doing the first connect.
The PR also introduces freerdp_reset_context which restores the initial
connection settings for the given instance.
__LINE__ is not particularily well defined (most fall back to int).
We want to ensure that all the uses in a format string match the format
specifier, so do an explicit cast
The shadow server tries to resize the client to use a compatible
resolution. If that fails, e.g. if there is another resize request after
the disconnect/reconnect sequence, abort the connection.
This patch introduce the basic architecture to intercept content of dynamic
channel. When a dynamic channel is in intercept mode, we accumulate and reassemble
the current packet so that it can be passed for inspection.
When some channels are filtered, some misalignement of channel ids could happen.
This patch keeps track of the back and front channel ids to correctly identify a
channel and send packets with the correct channel id.
* 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
Previously smartcard authentication was only supported with TLS
connections so the proxy forced that security mode.
Since we now have a working NLA smartcard auth implementation we can
remove that code and leave the correct configuration to the proxy user.
