Exposing lzcnt in crt.h might causes compiler errors (redefinition) with
recent versions of gcc (>=4.9) when winpr is included in other projects.
As lzcnt isn't part of crt according to MSDN and also shouldn't be
exported by default it was moved to intrin.h.
The related test was also moved to the top level directory of winpr.
The grid is composed of 64x64 blocks and should not be smaller
than the surface. If width or height were not a multiple of 64
the previous rounding resulted in a grid smaller than the surface.
- handle WAIT_TIMEOUT result as error in async transport thread
if an INFINITE timeout was specified in WaitForMultipleObjects
- fix mfreerdp's async transport handling to not use
freerdp_get_event_handles/freerdp_check_event_handles if async
transport is activated
It's unclear why this option would be necessary, and it causes problems
when people do not match it to their toolchain and CFLAGS.
To set the float abi, either use a toolchain with an appropriate default
or set the float-abi option in the CFLAGS environment variable.
This should resolve#2586.
1)
Added missing checks for CreateEvent which also required the
following related changes:
- changed freerdp_context_new API to BOOL
- changed freerdp_peer_context_new API to BOOL
- changed pRdpClientNew callback to BOOL
- changed pContextNew callback to BOOL
- changed psPeerAccepted callback to BOOL
- changed psPeerContextNew callback to BOOL
2)
Fixed lots of missing alloc and error checks in the
changed code's neighbourhood.
3)
Check freerdp_client_codecs_prepare result to avoid segfaults
caused by using non-initialized codecs.
4)
Fixed deadlocks in x11 caused by missing xf_unlock_x11() calls
in some error handlers
5)
Some fixes in thread pool:
- DEFAULT_POOL assignment did not match TP_POOL definition
- don't free the pool pointer if it points to the static DEFAULT_POOL
- added error handling and cleanup in InitializeThreadpool
When a hdc is created no initial or default objects are created
therefore can the first call of gdi_SelectObject return NULL.
Because of this checking the return value of gdi_SelectObject failed
for newly create hdc causing errors (disconnects).
Since all types of HGDIOBJECT are handled and the return value of
gdi_SelectObject isn't used the recently added checks were removed
again.

* top level GDI functions return 0 on error and != 0 otherwise but the
low level functions (16bpp.c, 8bpp.c 32bpp.c) which are called did it
exactly the other way around. Those were adapted.
* change gdi_InvalidateRegion to BOOL and check calls where appropriate
* integrate comments from pull request
Now using nCount as in and out argument.
When called, set nCount to the number of available handles.
This value is checked and an error returned, if not enough
handles are available.
* Though not frequent, it's possible to get TsProxySetupReceivePipe
data of stublength 4 that is actual data. This happens when
header->common.call_id == rpc->PipeCallId &&
!(header->common.pfc_flags & PFC_LAST_FRAG).
This should address GW disconnects that manifest as SSL read errors.
This is a fix for #2399: when there's no variants we should not try to scan them.
I have set the RDP US keyboard for the South African layout, if someone has a better
layout...
Note: we should probably set something that is not zero for other layouts
Change the return type of Stream_Ensure*Capacity from void to BOOL to be
able to detect realloc problems easily. Otherwise the only way to detect
this was to check if the capacity after the call was >= the required
size.
In case Stream_Ensure*Capacity fails the old memory is still available
and need to freed outside.
This commit also adds checks to most calls of Stream_Ensure*Capacity to
check if the call was successful.
Microsoft iOS Remote Desktop Clients eventually send NULL-terminated
hostnames in SNI which is not allowed in the OpenSSL implementation.
Since we're not using SNI this commit adds an OpenSSL TLS extension
debug callback which modifies the SSL context in a way preventing it
from parsing this extension
The X.224 Connection Request PDU might contain an optional cookie or
routing token before the optional RDP Negotiation Request (rdpNegReq).
If present, both of these fields must be terminated by a 0x0D0A
two-byte sequence. It seems that until now FreeRDP has incorrectly
assumed that a token or cookie must always be present.
If that was not the case, FreeRDP was searching for 0x0D0A until it
arrived at the end of the stream which prevented the remaining data
(RDP Negotiation Request, RDP Correlation Info) from being parsed.
tls_disconnect shut down the ssl stream but didn't inform
the BIO(s) about this therefore could happen that a second shut down
was initiated (e.g. in bio_rdp_tls_free) causing rather long delays.
After removing the shut down from tls_disconnect the only thing the
function does is to prepare/send an alert therefore it was renamed to
tls_send_alert.
See Issue #2443.
When there's more than 2 rectangles in the region structure, region16_intersect_rect would calculate extents by all 'intersected' sub rectangles.
But it always extend the extents to (0,0) because it initialize the new extents as (0,0,0,0) and union later rectangles with this empty point by simple MIN/MAX calculation.
Also fixed rectangle_is_empty although it has not been used yet. The function does not work as its name.
Reuse norbert case. That case is enough for the intersect fix, but the expected result is not correct. The test case is also fixed.
Added test case to check empty rectangle.
Currently the certificate format expected in FreeRDPs certificate store
is DER (ASN1). On most linux/unix systems the system certificate store
default format is PEM. Which is also the more common format used by CAs
to distribute their certificates.
Changing the default format to PEM allows the usage of system
certificates or published CA certificates without the need to convert them.
This fixes a part of issue #2446.
To do this I've swapped _strnicmp with memcmp. Seemless, but does lock it to the restrictions of that function.

Command line detection is run with dummy settings where not everything
is allocated. Collections (device, dynamic channel and static
channel) didn't handle this case properly.
Small cleanup of passing around decorations flag.
Limit PercentScreen to single monitor vs. entire desktop. IMO - this is better behavior in a multimonitor environment.
Handle fullscreen windows better:
1. Ensure that size hints are set to allow resizing before setting a window to fullscreen as some window managers do not behave properly.
2. Handle fullscreen toggles without destroying and recreating window.
3. Use NET_WM_STATE_FULLSCREEN Extended Window Manager Hint for fullscreen functionality
4. Use the NET_WM_FULLSCREEN_MONITORS Extended Window Manager Hint when appropriate
5. When a single monitor fullscreen is requested - use the current monitor(as determined from mouse location)
6. Handle cases where there is no local monitor at coordinate 0,0. The Windows server expect there to be a monitor at this location, so we maintain offset if necessary between our local primary monitor and the server side primary monitor located at 0,0.
Situation: we have fragmented TPKT PDU without two last bytes
(or one last byte - for fast-path) in network stack.
First call to transport_read_pdu() works normally, read
available bytes and exit with status 0 - no whole PDU readed.
Before second call this missed bytes arrive.
Optionally with next PDU.
In second call header parsing code unconditionally read this
two bytes(one byte) despite this is not header bytes.
And increase stream position, so stream now contains whole PDU.
This cause (pduLength - Stream_GetPosition(s)) calculation to be 0.
So transport_read_layer_bytes()-->transport_read_layer() return 0
and transport_read_pdu() exits with "not enough data is available"
status.
If next PDU isn't available next calls to transport_read_pdu()
give same result.
If next PDU arrive - (pduLength - Stream_GetPosition(s)) will be
less than 0. Stream position will grow, grow and grow on each call.
And transport_read_pdu() never signals that PDU is readed.
Caught on Android FreeRDP client with high RDP traffic (several MBytes/s).
Keepalive settings are usually (depending on the implementation) only
used if the TCP connection is idle.
If the network is interrupted/disconnected/... click or keyboard input
generates outgoing traffic therefore the connection isn't idle
anymore and keepalives might not be used causing the connection to
stay open and the client to stall.
Linux 2.6.36 added a TCP_USER_TIMEOUT TCP socket option that lets a
program specify the maximum time transmitted data may remain
unacknowledged before TCP will close the corresponding connection with
ETIMEDOUT.
Setting TCP_USER_TIMEOUT allows us to detect a network problem (like
cable disconnect) even if the connection isn't idle.
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.
WTSStartRemoteControlSession doesn't allow to specify additional flags
therefore add a new extended version WTSStartRemoteControlSessionEx
with an additional "flags" parameter.
The following flags are defined:
REMOTECONTROL_FLAG_DISABLE_KEYBOARD - disable keyboard input
REMOTECONTROL_FLAG_DISABLE_MOUSE - disable mouse input
REMOTECONTROL_FLAG_DISABLE_INPUT - disable input (keyboard and mouse)
This patch fixes a bug with mstsc connecting to a RDP security only FreeRDP server.
It seems like the mstsc shipped with Windows Seven considers packets after the nego_failure
packet as an error. So after trying to do TLS, depending on the timing, mstsc can print an
error message instead of retrying to connect with RDP security. With this patch, we
don't send the MCS disconnect message when the negociation has failed.
Before this patch, RDP security was (wrongly) the fallback when negociating a
security protocol between the client and the server. For example when a client
was claiming TLS-only when connecting to a FreeRDP based-server with RDP security only,
the result of the negociation was that the server started to do RDP security.
The expected behaviour is to send a nego failure packet with error code
SSL_NOT_ALLOWED_BY_SERVER. This patch fixes this.
We also try to handle all cases of failed negociation and return the corresponding
error code.
