* LibVNCServer: fix starting of an onHold-client in threaded mode.Christian Beier2016-12-281-9/+6
| | | | | | | | Discovered by madscientist159 on 11 Jan 2015: "noted in testing with the threaded server build, whereby if newClientHook() returned RFB_CLIENT_ON_HOLD there was no way to release the hold when the server became ready"

* Fix handling of multiple VNC commands per websockets frameFloris Bos2015-01-171-0/+8
| | | | | | | | | | | | | - When processing input, check if there is any extra data pending in the internal websocket frame and SSL buffers. - Prevents input events lagging behind because they get stuck in one of the buffers. Data pending in our own buffers cannot be detected with select() so was not processed until more input arrives from the network. - Closes # 55 Signed-off-by: Floris Bos <bos@je-eigen-domein.nl>

| | | | | | too. As done with the RFB sockets, this uses a separate-socket approach as well.
* IPv6 support for LibVNCServer, part onepointsix: fix a small logic error.Christian Beier2012-02-271-1/+1
| | | | | Without this, we would have gotten a stale IPv4 socket in a race condition.
* IPv6 support for LibVNCServer, part one: accept IPv4 and IPv6 connections.Christian Beier2012-02-201-10/+28
| | | | | | | | | This uses a separate-socket approach since there are systems that do not support dual binding sockets under *any* circumstances, for instance OpenBSD. Using separate sockets for IPv4 and IPv6 is thus more portable than having a v6 socket handle v4 connections as well. Signed-off-by: Christian Beier <dontmind@freeshell.org>

* Split two event-loop related functions out of the rfbProcessEvents() mechanism.George Kiagiadakis2011-06-011-25/+37
| | | | | | | This is required to be able to do proper event loop integration with Qt. Idea was taken from vino's libvncserver fork. Signed-off-by: Christian Beier <dontmind@freeshell.org>
* libvncserver: Make RRE, CoRRE and Ultra encodings thread-safe.Christian Beier2011-02-071-3/+0
| | | | | | | This adds generic before/after encoding buffers to the rfbClient struct, so there is no need for thread local storage. Signed-off-by: Christian Beier <dontmind@freeshell.org>

* libvnc[server|client]: implement xvp VNC extension.Christian Beier2010-11-021-0/+1
| | | | | | | This implements the xvp VNC extension, which is described in the community version of the RFB protocol: http://tigervnc.sourceforge.net/cgi-bin/rfbproto It is also mentioned in the official RFB protocol.
* Added missing initialization of extension mutexTobias Doerffel2010-10-291-0/+5
| | | | | | | | | | When not calling rfbRegisterProtocolExtension() the extension mutex is uninitialized but used upon calling rfbGetExtensionIterator() and rfbReleaseExtensionIterator() in rfbNewTCPOrUDPClient(). This causes libvncserver to crash on Win32 when building with thread support. Signed-off-by: Tobias Doerffel <tobias.doerffel@gmail.com> Signed-off-by: Christian Beier <dontmind@freeshell.org>

* Fix a locking problem in libvncserverdscho2007-03-171-2/+1
| | | | | | | | | | | | | | | | | | | There seems to be a locking problem in libvncserver, with respect to how condition variables are used. On certain machines in our lab, when using a vncviewer to view a display that has a very high rate of updates, we will occasionally see the VNC server process crash. In one stack trace that was obtained, an assertion had tripped in glibc's pthread_cond_wait, which was called from clientOutput. Inspection of clientOutput suggests that WAIT is being called incorrectly. The mutex that protects a condition variable should always be locked when calling wait, and on return from the wait will still be locked. The attached patch fixes the locking around this condition variable, and one other that I found by grepping the source for similar occurrences. Signed-off-by: Charles Coffing <ccoffing@novell.com>
