TPKT header length and consumption of data was not consistently
checked. This adds checks after each packet processed and fixes
any inconsistencies found.
Dropped some warning that were caused by the DEBUG_CAPABILTIES define.
Also adjusted some lines that were quite ugly after the automatic truncation
to 80 characters.
FreeRDP calculates default request size in server mode based upon
the desktop resolution. In practice, however, I've found clients (namely
MS Lync 2013) which would show only a black screen when the value is
greater than 0x3EFFFF.
This change allows to override the default in such special cases by
assigning a different value to server->settings->MultifragMaxRequestSize
after the shadow server structure is initialized in shadow_server_new().
- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments
- use inttypes defines where appropriate
Most of the capabilities are sent by both the client and the server. But for some
the specs specify that they are only supposed to be only send by the server or the client.
This patch ensures this. Without this patch a malicious client can change server settings
and a malicious server can modify client settings.
Horizontal mouse wheel input capabilities are now checked
and if available mouse buttons 6 and 7 are mapped to the
horizontal wheel for the X11 client.
refreshRectSupport and suppressOutputSupport of the General
Capability Set (MS-RDPBCGR 2.2.7.1.1) are server-only flags
that indicate whether the Refresh Rect or Suppress Output
PDUs are supported by the server.
Therefore in rdp_read_general_capability_set() we must only
change the respective settings if we are not in server mode.
Commit 0357a38e31 has added some code
without any effect.
That commit added code to rdp_read_capability_sets() to check if
CAPSET_TYPE_MULTI_FRAGMENT_UPDATE was not received which caused
settings->MultifragMaxRequestSize to be set to 0.
- this was done in the wrong place because we do these kind
of checks in rdp_recv_confirm_active() by consulting the
variable settings->ReceivedCapabilities[]
- the code had no effect at all because MultifragMaxRequestSize gets
set to FASTPATH_FRAGMENT_SAFE_SIZE in rdp_recv_confirm_active()
if the CAPSET_TYPE_MULTI_FRAGMENT_UPDATE was not received.
