Since ec027bf dynamic resolution is broken when used with egfx. Before that commit
we were tracking a server sent resize by setting a DesktopResize callback. This callback
is called when the desktop is resized by the server. Anyway the problem was that when this
callback is called, the activation sequence is not always completed, which were leading to
some freeze with 2012r2 servers (sending packets before the sequence is finished).
So with the faulty commit, we are tracking server resizes by subscribing to the Actived
event, that is called at the end of a reactivation sequence, so we're sure to not send packets
when not fully activated.
Anyway the issue that shows on (#4330) is that when you use egfx, no reactivation sequence happens,
the server only sends a ResetGraphics message with the new size, and so we miss the resized event.
This fix introduces a new GraphicsReset event, makes the display channel subscribe to that event,
and react accordingly.
Added some checks so that when setting a cache entry fails, we close connection (or
we fail later when trying to use that empty entry).
The small cache egfx capability has also been fixed.
- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments
- use inttypes defines where appropriate
Not use sizeof on packet memory structure for stream length check/estimating and use number directly.
Most of the packet size could be obviously calculated/verified from code and comments in same function.
Macro is defined for those were referenced multiple times.
1. Fix style for channels/rdpgfx/server/rdpgfx_main.c according to scripts/format_code.sh
2. Refactor and introduce APIs to allow rdpgfx server channel running in existing thread (similar to rdpsnd)
1. Fix stream leak in rdpgfx
2. Make src data const in zgfx. Harden zgfx to be independent to byte order
3. Fix written bytes return value in channel write
4. Add check for return value in shadow_client.c
5. Add gfx callback to send surface command with frame marker pdu.
6. Check remain length for recv subroutine
7. Fix compile errors
