* libvncclient/ultra.c: Fix heap overflow in the ultra.c decoder The Ultra type tile decoder does not use the _safe variant of the
LZO decompress function, which allows a maliciuous server to
overwrite parts of the heap by sending a larger-than-specified LZO
data stream.
2016-11-14 Josef Gajdusek <atx@atx.name>
* libvncclient/rfbproto.c: Fix heap overflows in the various
rectangle fill functions Altough rfbproto.c does check whether the overall FramebufferUpdate
rectangle is too large, some of the individual encoding decoders do
not, which allows a malicious server to overwrite parts of the heap.
2016-09-24 Christian Beier <dontmind@freeshell.org>
* : Merge pull request #129 from bkylerussell/systemd Support systemd socket activation
2016-08-14 Zac Medico <zmedico@gmail.com>
* libvncserver/sockets.c: Support autoPort with ipv4 or ipv6
disabled Make it possible to get autoPort behavior with either ipv4 or ipv6
disabled, by setting rfbScreen->ipv6port or rfbScreen->port to a
negative number. This will make it possible for x11vnc to enforce
its -noipv6 option, as discussed in the following bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=672449

platforms.
2016-05-13 George Fleury <gfleury@gmail.com>
* libvncserver/sockets.c: Avoid calling SSL_pending when connection
is already closed Avoid calling SSL_pending when connection is already closed, calling
SSL_pending with connection already closed is crashing. To
reproduce, open a secure websocket binay protocol connection with
libvncserver compiled with OpenSSL, and when libvncserver is waiting
for rfbProcessClientProtocolVersion send any invalid char, it will
fail and call rfbCloseClient whith destroy all SSL context, calling
SSL_pending after that will generate a invalid access.

* libvncserver/scale.c: Fix Use-After-Free vulnerability in
LibVNCServer wrt scaling. Reported by Ken Johnson <Ken.Johnson1@telus.com>. The vulnerability would occur in both the rfbPalmVNCSetScaleFactor
and rfbSetScale cases in the rfbProcessClientNormalMessage function
of rfbserver.c. Sending a valid scaling factor is required
(non-zero) if (msg.ssc.scale == 0) { rfbLogPerror("rfbProcessClientNormalMessage: will not
accept a scale factor of zero"); rfbCloseClient(cl); return; } rfbStatRecordMessageRcvd(cl, msg.type, sz_rfbSetScaleMsg,
sz_rfbSetScaleMsg); rfbLog("rfbSetScale(%d)\n",
msg.ssc.scale); rfbScalingSetup(cl,cl->screen->width/msg.ssc.scale,
cl->screen->height/msg.ssc.scale); rfbSendNewScaleSize(cl); << This is the call that can trigger
a free. return; at the end, both cases there is a call the rfbSendNewScaleSize
function, where if the connection is subsequently disconnected after
sending the VNC scaling message can lead to a free occurring. else { rfbResizeFrameBufferMsg rmsg; rmsg.type = rfbResizeFrameBuffer; rmsg.pad1=0; rmsg.framebufferWidth =
Swap16IfLE(cl->scaledScreen->width); rmsg.framebufferHeigth
= Swap16IfLE(cl->scaledScreen->height); rfbLog("Sending a response
to a UltraVNC style frameuffer resize event (%dx%d)\n",
cl->scaledScreen->width, cl->scaledScreen->height); if
(rfbWriteExact(cl, (char *)&rmsg, sz_rfbResizeFrameBufferMsg) < 0) {
rfbLogPerror("rfbNewClient: write"); rfbCloseClient(cl); rfbClientConnectionGone(cl); << Call which may can lead
to a free. return FALSE; } } return TRUE; Once this function returns, eventually rfbClientConnectionGone is
called again on the return from rfbProcessClientNormalMessage. In
KRFB server this leads to an attempt to access client->data.

* libvncclient/rfbproto.c: Fix possible libvncclient ServerInit
memory corruption. This fixes the following oCERT report (oCERT-2014-008 pt.2): There is a similar vulnerability to the previous one I sent. This is
related to the ServerInit message where the width, the height of the
server's framebuffer, its pixel format, and the name are sent to the
client. The name can be used in a malicious manner to trigger a
memory corruption in the client. Field Size --------------------------------- name-length
[4] name-string [name-length] Below you will find a PoC script to show the vulnerability. This was
tested on Fedora 20 with the latest version of krdc. I have noticed something, where the memory corruption causes the
program to hang but allows you to try to disconnect. After this it
hangs. Occasionally there will be segmentation fault in memcpy. This
can become more reliable if you connect to a different VNC server
first (Or the wrong port on the malicious server) then connecting to

* libvncclient/sockets.c: Fix potential memory corruption in
libvncclient. Fixes (maybe amongst others) the following oCERT report
([oCERT-2014-008]): LibVNCServer HandleRFBServerMessage rfbServerCutText malicious
msg.sct.length It looks like there may be a chance for potential memory corruption
when a LibVNCServer client attempts to process a Server Cut Text
message. case rfbServerCutText: { char *buffer; if (!ReadFromRFBServer(client, ((char *)&msg) + 1, sz_rfbServerCutTextMsg - 1)) return FALSE; msg.sct.length = rfbClientSwap32IfLE(msg.sct.length); <<
Retrieve malicious length buffer = malloc(msg.sct.length+1); << Allocate buffer. Can
return 0x0 if (!ReadFromRFBServer(client, buffer, msg.sct.length)) <<
Attempt to write to buffer return FALSE; buffer[msg.sct.length] = 0; << Attempt to write to buffer if (client->GotXCutText) client->GotXCutText(client, buffer, msg.sct.length); <<
Attempt to write to buffer free(buffer); break; } If a message is provided with an extremely large size it is possible
to cause the malloc to fail, further leading to an attempt to write
0x0.

2014-10-07 dscho <johannes.schindelin@gmx.de>
* : Merge pull request #42 from LibVNC/autotools-fix-revisited Add autoconf macros that might not be installed with a usual
autotools setup
2014-10-07 Johannes Schindelin <johannes.schindelin@gmx.de>
* autogen.sh: Add back a working autogen.sh There was no reason to get rid of the convenient script. Most
developers who are not in love with autoconf fail to remember that
autoreconf invocation, therefore it is better to have something
working in place. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2014-09-01 Nicolas Ruff <nruff@google.com>

* : Merge pull request #36 from danielgindi/master A forgotten `#ifdef WIN32` broke UNIX build.
2014-09-30 dscho <johannes.schindelin@gmx.de>
* : Merge pull request #33 from danielgindi/master More MSVC adjustments, now focuses on the libvncserver
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/tightvnc-filetransfer/handlefiletransferrequest.c:
These are UNIX headers, and are not available on MSVC
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* rfb/rfb.h: Those are generally the windows headers, not just MinGW
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/rfbserver.c: On windows, use the Win32 calls for
directory enumerations. We also do not need the conversion between UNIX values to Windows
values in the RTF_FIND_DATA struct, as we already are on windows.
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/httpd.c, libvncserver/rfbserver.c,
libvncserver/sockets.c, rfb/rfbclient.h: Generally adjusting headers
for compiling on windows without the mixing of Winsock 1 and 2.
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/rfbserver.c: Just use a macro to bridge to the Win32
version of `mkdir` The additional compat_mkdir function was not necessary at all.
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* compat/msvc/sys/time.h: Use correct `winsock2.h` version header
instead of winsock.h. `windows.h` is referring to `winsock.h` (unless the
`WIN32_LEAN_AND_MEAN` is defined). The structs used in this header
are defined in `winsock2.h` or in `winsock.h`, but we are using
Winsock2 of course! So we have to include winsock2.h and refrain
from including windows.h here
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/httpd.c, libvncserver/rfbserver.c,
libvncserver/sockets.c: Fixed a violation of the C89 standard
("declarations must come before instructions")
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/tightvnc-filetransfer/filetransfermsg.c: A windows
version for directory enumerations Basically taken from https://github.com/danielgindi/FileDir with
some adjustments
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/tightvnc-filetransfer/filetransfermsg.c: MSVC also
has the __FUNCTION__ predefined
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/tightvnc-filetransfer/filetransfermsg.c,
libvncserver/tightvnc-filetransfer/filetransfermsg.h:
`CreateDirectory` might clash with the
`CreateDirectoryA`/`CreateDirectoryW` macros on MSVC
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncserver/tightvnc-filetransfer/filetransfermsg.c: Fail when
NULL is passed to CreateFileListInfo() Passing NULL to sprintf() would most likely crash the program.
2014-09-20 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncclient/rfbproto.c, libvncclient/vncviewer.c,
libvncserver/rfbserver.c, libvncserver/sockets.c,
libvncserver/stats.c, libvncserver/websockets.c: `strings.h` and
`resolv.h` are not available on MSVC, and some POSIX functions are
renamed or deprecated For all of those missing/deprecated POSIX functions, we just add a
macro mapping to the _underscored version of MSVC.
2014-09-09 Christian Beier <dontmind@freeshell.org>

2014-08-29 Daniel Cohen Gindi <danielgindi@gmail.com>
* libvncclient/tls_openssl.c: Use Windows' critical sections to
emulate pthread's mutexes With Microsoft Visual C++, we cannot use pthreads (MinGW sports an
emulation library which is the reason we did not need
Windows-specific hacks earlier). Happily, it is very easy to provide
Windows-specific emulations for the pthread calls we use. [JES: fixed commit message] Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

* x11vnc/xrandr.c: x11vnc: fix double X_UNLOCK on xrandr events check_xrandr_event() assumes X_LOCK is taken before it is called,
and currently calls X_UNLOCK on behalf of the caller. But in
practice, all callers assume that the lock is still held after
check_xrandr_event() returns. In particular, this leads to a
double-unlock and crash in check_xevents() on any xrandr event.

* CMakeLists.txt: Use CMAKE_CURRENT_*_DIR instead of CMAKE_*_DIR. This makes the library friendly to use as a git submodule within
another project, and should change nothing when compiled alone. For example when having a directory structure like
"my_project/external/libvnc", where in libvnc resides a checkout of
libvncserver, one can just reference that directory from the
CMakeLists.txt in my_project with > add_directory ( external/libvnc ) and add vncclient / vncserver in my_project's taret_link_libraries,
one can just hack away without having to manually make / install
LibVNCServer whenever something is changed there.

rfb/rfbproto.h: LibVNCClient: Add H.264 encoding for framebuffer
updates This patch implements support in LibVNCClient for framebuffer
updates encoded as H.264 frames. Hardware accelerated decoding is
performed using VA API. This is experimental support to let the community explore the
possibilities offered by the potential bandwidth and latency
reductions that H.264 encoding allows. This may be particularly
useful for use cases such as online gaming, hosted desktops, hosted
set top boxes... This patch only provides the client side support and is meant to be
used with corresponding server-side support, as provided by an
upcoming patch for qemu ui/vnc module (to view the display of a
virtual machine executing under QEMU). With this H.264-based encoding, if multiple framebuffer update
messages are generated for a single server framebuffer modification,
the H.264 frame data is sent only with the first update message.
Subsequent update framebuffer messages will contain only the
coordinates and size of the additional updated regions. Instructions/Requirements: * The patch should be applied on top of the previous patch I
submitted with minor enhancements to the gtkvncviewer application:
http://sourceforge.net/mailarchive/message.php?msg_id=30323804 * Currently only works with libva 1.0: use branch "v1.0-branch" for

2012-09-11 Raphael Kubo da Costa <rakuco@FreeBSD.org>
* CMakeLists.txt, configure.ac, libvncserver/websockets.c,
rfb/rfbconfig.h.cmake: Use htobeNN(3) to convert numbers in
websocket.c. byteswap.h exists only on glibc, so building libvncserver with
websockets support was not possible in other systems. Replace the inclusion of byteswap.h and the WS_* definitions with
calls to htobeNN, which should perform the same conversions, be more
portable and avoid the need to check for the platform's endianness.
2012-09-11 Raphael Kubo da Costa <rakuco@FreeBSD.org>
* CMakeLists.txt, configure.ac: Do not hardcode the need for
libresolv. libresolv is only present on systems which use glibc; platforms such
as FreeBSD have __b64_ntop as part of libc itself. Improve the detection process and only link against libresolv if it
exists on the system, and remember to reset CMAKE_REQUIRED_LIBRARIES
after performing the necessary tests, since we do not always want to
link against libresolv.

libvncclient/sockets.c, libvncserver/httpd.c,
libvncserver/rfbserver.c, libvncserver/sockets.c,
libvncserver/websockets.c: Tune the definitions needed when building
with -ansi. The current definitions were mostly useful to glibc and followed its
feature_test_macros(3) documentation. However, this means other platforms still had problems when building
with strict compilation flags. _BSD_SOURCE, for example, is only
recognized by glibc, and other platforms sometimes need
_XOPEN_SOURCE instead, or even the removal of some definitions (such
as the outdate _POSIX_SOURCE one). _POSIX_SOURCE also had to be conditionally defined in some places,
as what it enables or disables during compilation varies across
systems.
2012-09-11 Raphael Kubo da Costa <rakuco@FreeBSD.org>
* libvncserver/sockets.c, libvncserver/websockets.c: Add some
missing feature macro definitions. Building with -ansi failed due to some code (as well as system
headers) using non-C89 features. Fix that by adding the usual
_POSIX_SOURCE and _BSD_SOURCE definitions already present in some
other files.
2012-09-11 Raphael Kubo da Costa <rakuco@FreeBSD.org>
* common/turbojpeg.c, libvncserver/tight.c,
libvncserver/websockets.c, rfb/rfb.h, rfb/rfbconfig.h.cmake,
test/bmp.h: Use C-style comments in rfbconfig.h.cmake and C source
code. Using C++-style comments when building the code with -ansi does not
work, so be more conservative with the comment style.
2012-09-11 Raphael Kubo da Costa <rakuco@FreeBSD.org>
* libvncserver/websockets.c: Correctly include rfbconfig.h. build_dir/rfb is not passed as an include directory automatically to
the compiler, so including that file fails.
2012-09-11 Raphael Kubo da Costa <rakuco@FreeBSD.org>
* CMakeLists.txt: CMake: Link against libgcrypt when it is found. So far, libgcrypt was looked for but no targets linked against it
directly; this caused linking problems for the client and server
examples, as the symbols they needed were not passed to the linker. The issue that the GnuTLS websockets code uses libgcrypt regardless
of whether it has been found or not has not been touched by this
commit, though.

Replace TightVNC encoder with TurboVNC encoder. This patch is the
result of further research and discussion that revealed the
following: -- TightPng encoding and the rfbTightNoZlib extension need not
conflict. Since TightPng is a separate encoding type, not supported
by TurboVNC-compatible viewers, then the rfbTightNoZlib extension
can be used solely whenever the encoding type is Tight and disabled
with the encoding type is TightPng. -- In the TightVNC encoder, compression levels above 5 are basically
useless. On the set of 20 low-level datasets that were used to
design the TurboVNC encoder (these include the eight 2D application
captures that were also used when designing the TightVNC encoder, as
well as 12 3D application captures provided by the VirtualGL
Project-- see
http://www.virtualgl.org/pmwiki/uploads/About/tighttoturbo.pdf),
moving from Compression Level (CL) 5 to CL 9 in the TightVNC
encoder did not increase the compression ratio of any datasets more
than 10%, and the compression ratio only increased by more than 5%
on four of them. The compression ratio actually decreased a few
percent on five of them. In exchange for this paltry increase in
compression ratio, the CPU usage, on average, went up by a factor of
5. Thus, for all intents and purposes, TightVNC CL 5 provides the
"best useful compression" for that encoder. -- TurboVNC's best compression level (CL 2) compresses 3D and video
workloads significantly more "tightly" than TightVNC CL 5 (~70%
better, in the aggregate) but does not quite achieve the same level
of compression with 2D workloads (~20% worse, in the aggregate.)
This decrease in compression ratio may or may not be noticeable,
since many of the datasets it affects are not performance-critical
(such as the console output of a compilation, etc.) However, for
peace of mind, it was still desirable to have a mode that compressed
with equal "tightness" to TightVNC CL 5, since we proposed to
replace that encoder entirely. -- A new mode was discovered in the TurboVNC encoder that produces,
in the aggregate, similar compression ratios on 2D datasets as
TightVNC CL 5. That new mode involves using Zlib level 7 (the same
level used by TightVNC CL 5) but setting the "palette threshold" to
256, so that indexed color encoding is used whenever possible. This
mode reduces bandwidth only marginally (typically 10-20%) relative
to TurboVNC CL 2 on low-color workloads, in exchange for nearly
doubling CPU usage, and it does not benefit high-color workloads at
all (since those are usually encoded with JPEG.) However, it
provides a means of reproducing the same "tightness" as the TightVNC encoder on 2D workloads without sacrificing any compression for
3D/video workloads, and without using any more CPU time than
necessary. -- The TurboVNC encoder still performs as well or better than the
TightVNC encoder when plain libjpeg is used instead of
libjpeg-turbo. Specific notes follow: common/turbojpeg.c common/turbojpeg.h: Added code to emulate the
libjpeg-turbo colorspace extensions, so that the TurboJPEG wrapper
can be used with plain libjpeg as well. This required updating the
TurboJPEG wrapper to the latest code from libjpeg-turbo 1.2.0,
mainly because the TurboJPEG 1.2 API handles pixel formats in a much
cleaner way, which made the conversion code easier to write. It
also eases the maintenance to have the wrapper synced as much as
possible with the upstream code base (so I can merge any relevant
bug fixes that are discovered upstream.) The libvncserver version of
the TurboJPEG wrapper is a "lite" version, containing only the JPEG
compression/decompression code and not the lossless transform, YUV
encoding/decoding, and dynamic buffer allocation features from
TurboJPEG 1.2. configure.ac: Removed the --with-turbovnc option. configure still
checks for the presence of libjpeg-turbo, but only for the purposes
of printing a performance warning if it isn't available. rfb/rfb.h: Fix a bug introduced with the initial TurboVNC encoder
patch. We cannot use tightQualityLevel for the TurboVNC 1-100
quality level, because tightQualityLevel is also used by ZRLE.
Thus, a new parameter (turboQualityLevel) was created. rfb/rfbproto.h: Remove TurboVNC-specific #ifdefs and language libvncserver/rfbserver.c: Remove TurboVNC-specific #ifdefs. Fix
afore-mentioned tightQualityLevel bug. libvncserver/tight.c: Replaced the TightVNC encoder with the
TurboVNC encoder. Relative to the initial TurboVNC encoder patch,
this patch also: -- Adds TightPng support to the TurboVNC encoder --
Adds the afore-mentioned low-bandwidth mode, which is mapped
externally to Compression Level 9 test/*: Included TJUnitTest (a regression test for the TurboJPEG
wrapper) as well as TJBench (a benchmark for same.) These are
useful for ensuring that the wrapper still functions correctly and
performantly if it needs to be modified for whatever reason. Both
of these programs are derived from libjpeg-turbo 1.2.0. As with the
TurboJPEG wrapper, they do not contain the more advanced features of
TurboJPEG 1.2, such as YUV encoding/decoding and lossless
transforms.

* libvncserver/rfbserver.c: Fix an issue that affects the existing
Tight encoder as well as the newly-implemented Turbo encoder. The issue is that, when using the current libvncserver source, it is
impossible to disable Tight JPEG encoding. The way Tight/Turbo
viewers disable JPEG encoding is by simply not sending the Tight
quality value, causing the server to use the default value of -1.
Thus, cl->tightQualityLevel has to be set to -1 prior to processing
the encodings message for this mechanism to work. Similarly, it is
not guaranteed that the compress level will be set in the encodings
message, so it is set to a default value prior to processing the
message.

libvncserver/Makefile.am, libvncserver/rfbserver.c,
libvncserver/turbo.c, rfb/rfb.h, rfb/rfbproto.h: Add TurboVNC
encoding support. TurboVNC is a variant of TightVNC that uses the same client/server
protocol (RFB version 3.8t), and thus it is fully cross-compatible
with TightVNC and TigerVNC (with one exception, which is noted
below.) Both the TightVNC and TurboVNC encoders analyze each
rectangle, pick out regions of solid color to send separately, and
send the remaining subrectangles using mono, indexed color, JPEG, or
raw encoding, depending on the number of colors in the subrectangle.
However, TurboVNC uses a fundamentally different selection algorithm
to determine the appropriate subencoding to use for each
subrectangle. Thus, while it sends a protocol stream that can be
decoded by any TightVNC-compatible viewer, the mix of subencoding
types in this protocol stream will be different from those generated
by a TightVNC server. The research that led to TurboVNC is described in the following
report:
http://www.virtualgl.org/pmwiki/uploads/About/tighttoturbo.pdf. In
summary: 20 RFB captures, representing "common" 2D and 3D
application workloads (the 3D workloads were run using VirtualGL),
were studied using the TightVNC encoder in isolation. Some of the
analysis features in the TightVNC encoder, such as smoothness
detection, were found to generate a lot of CPU usage with little or
no benefit in compression, so those features were disabled. JPEG
encoding was accelerated using libjpeg-turbo (which achieves a 2-4x
speedup over plain libjpeg on modern x86 or ARM processors.)
Finally, the "palette threshold" (minimum number of colors that the
subrectangle must have before it is compressed using JPEG or raw)
was adjusted to account for the fact that JPEG encoding is now quite
a bit faster (meaning that we can now use it more without a CPU
penalty.) TurboVNC has additional optimizations, such as the
ability to count colors and encode JPEG images directly from the
framebuffer without first translating the pixels into RGB. The
TurboVNC encoder compares quite favorably in terms of compression
ratio with TightVNC and generally encodes a great deal faster (often
an order of magnitude or more.) The version of the TurboVNC encoder included in this patch is
roughly equivalent to the one found in version 0.6 of the Unix
TurboVNC Server, with a few minor patches integrated from TurboVNC
1.1. TurboVNC 1.0 added multi-threading capabilities, which can be
added in later if desired (at the expense of making libvncserver
depend on libpthread.) Because TurboVNC uses a fundamentally different mix of subencodings
than TightVNC, because it uses the identical protocol (and thus a
viewer really has no idea whether it's talking to a TightVNC or
TurboVNC server), and because it doesn't support rfbTightPng (and in
fact conflicts with it-- see below), the TurboVNC and TightVNC
encoders cannot be enabled simultaneously. Compatibility: In *most* cases, a TurboVNC-enabled viewer is fully compatible with
a TightVNC server, and vice versa. TurboVNC supports
pseudo-encodings for specifying a fine-grained (1-100) quality scale
and specifying chrominance subsampling. If a TurboVNC viewer sends
those to a TightVNC server, then the TightVNC server ignores them,
so the TurboVNC viewer also sends the quality on a 0-9 scale that
the TightVNC server can understand. Similarly, the TurboVNC server
checks first for fine-grained quality and subsampling
pseudo-encodings from the viewer, and failing to receive those, it
then checks for the TightVNC 0-9 quality pseudo-encoding. There is one case in which the two systems are not compatible, and
that is when a TightVNC or TigerVNC viewer requests compression
level 0 without JPEG from a TurboVNC server. For performance
reasons, this causes the TurboVNC server to send images directly to
the viewer, bypassing Zlib. When the TurboVNC server does this, it
also sets bits 7-4 in the compression control byte to rfbTightNoZlib
(0x0A), which is unfortunately the same value as rfbTightPng. Older
TightVNC viewers that don't handle PNG will assume that the stream
is uncompressed but still encapsulated in a Zlib structure, whereas
newer PNG-supporting TightVNC viewers will assume that the stream is
PNG. In either case, the viewer will probably crash. Since most
VNC viewers don't expose compression level 0 in the GUI, this is a
relatively rare situation. Description of changes: configure.ac -- Added support for libjpeg-turbo. If passed an
argument of --with-turbovnc, configure will now run (or, if cross-compiling, just link) a test program that determines
whether the libjpeg library being used is libjpeg-turbo.
libjpeg-turbo must be used when building the TurboVNC encoder,
because the TurboVNC encoder relies on the libjpeg-turbo
colorspace extensions in order to compress images directly out of
the framebuffer (which may be, for instance, BGRA rather than RGB.)
libjpeg-turbo can optionally be used with the TightVNC encoder as
well, but the speedup will only be marginal (the report linked above
explains why in more detail, but basically it's because of Amdahl's
Law. The TightVNC encoder was designed with the assumption that
JPEG had a very high CPU cost, and thus JPEG is used only
sparingly.) -- Added a new configure variable, JPEG_LDFLAGS. This
is necessitated by the fact that libjpeg-turbo often distributes
libjpeg.a and libjpeg.so in /opt/libjpeg-turbo/lib32 or
/opt/libjpeg-turbo/lib64, and many people prefer to statically
link with it. Thus, more flexibility is needed than is provided by
--with-jpeg. If JPEG_LDFLAGS is specified, then it overrides the
changes to LDFLAGS enacted by --with-jpeg (but --with-jpeg is
still used to set the include path.) The addition of JPEG_LDFLAGS
necessitated replacing AC_CHECK_LIB with AC_LINK_IFELSE (because
AC_CHECK_LIB automatically sets LIBS to -ljpeg, which is not what we
want if we're, for instance, linking statically with libjpeg-turbo.)
-- configure does not check for PNG support if TurboVNC encoding is
enabled. This prevents the rfbSendRectEncodingTightPng() function
from being compiled in, since the TurboVNC encoder doesn't (and
can't) support it. common/turbojpeg.c, common/turbojpeg.h -- TurboJPEG is a simple API
used to compress and decompress JPEG images in memory. It was
originally implemented because it was desirable to use different
types of underlying technologies to compress JPEG on different
platforms (mediaLib on SPARC, Quicktime on PPC Macs, Intel
Performance Primitives, etc.) These days, however, libjpeg-turbo
is the only underlying technology used by TurboVNC, so TurboJPEG's
purpose is largely just code simplicity and flexibility. Thus,
since there is no real need for libvncserver to use any technology
other than libjpeg-turbo for compressing JPEG, the TurboJPEG wrapper
for libjpeg-turbo has been included in-tree so that libvncserver can
be directly linked with libjpeg-turbo. This is convenient because
many modern Linux distros (Fedora, Ubuntu, etc.) now ship
libjpeg-turbo as their default libjpeg library. libvncserver/rfbserver.c -- Added logic to check for the TurboVNC
fine-grained quality level and subsampling encodings and to map
Tight (0-9) quality levels to appropriate fine-grained quality level
and subsampling values if communicating with a TightVNC/TigerVNC
viewer. libvncserver/turbo.c -- TurboVNC encoder (compiled instead of
libvncserver/tight.c) rfb/rfb.h -- Added support for the TurboVNC subsampling level rfb/rfbproto.h -- Added constants for the TurboVNC fine quality
level and subsampling encodings as well as the rfbTightNoZlib
constant and notes on its usage.

2011-10-26 Christian Beier <dontmind@freeshell.org>
* libvncserver/rfbserver.c: Fix deadlock in threaded mode when using
nested rfbClientIteratorNext() calls. Lengthy explanation follows... First, the scenario before this patch: We have three clients 1,2,3 connected. The main thread loops through
them using rfbClientIteratorNext() (loop L1) and is currently at
client 2 i.e. client 2's cl_2->refCount is 1. At this point we need
to loop again through the clients, with cl_2->refCount == 1, i.e. do
a loop L2 nested within loop L1. BUT: Now client 2 disconnects, it's clientInput thread terminates
its clientOutput thread and calls rfbClientConnectionGone(). This
LOCKs clientListMutex and WAITs for cl_2->refCount to become 0. This
means this thread waits for the main thread to release cl_2.
Waiting, with clientListMutex LOCKed! Meanwhile, the main thread is about to begin the inner
rfbClientIteratorNext() loop L2. The first call to
rfbClientIteratorNext() LOCKs clientListMutex. BAAM. This mutex is
locked by cl2's clientInput thread and is only released when
cl_2->refCount becomes 0. The main thread would decrement
cl_2->refCount when it would continue with loop L1. But it's waiting
for cl2's clientInput thread to release clientListMutex. Which never
happens since this one's waiting for the main thread to decrement
cl_2->refCount. DEADLOCK. Now, situation with this patch: Same as above, but when client 2 disconnects it's clientInput thread
rfbClientConnectionGone(). This again LOCKs clientListMutex, removes
cl_2 from the linked list and UNLOCKS clientListMutex. The WAIT for
cl_2->refCount to become 0 is _after_ that. Waiting, with
clientListMutex UNLOCKed! Therefore, the main thread can continue, do the inner loop L2 (now
only looping through 1,3 - 2 was removed from the linked list) and
continue with loop L1, finally decrementing cl_2->refCount, allowing
cl2's clientInput thread to continue and terminate. The resources
held by cl2 are not free()'d by rfbClientConnectionGone until
cl2->refCount becomes 0, i.e. loop L1 has released cl2.

* libvncserver/rfbserver.c: Fix memory leak I was debbuging some code tonight and i found a pointer that is not
been freed, so i think there is maybe a memory leak, so it is... there is the malloc caller reverse order: ( malloc cl->statEncList ) <- rfbStatLookupEncoding <- rfbStatRecordEncodingSent <- rfbSendCursorPos <- rfbSendFramebufferUpdate <- rfbProcessEvents I didnt look the whole libvncserver api, but i am using
rfbReverseConnection with rfbProcessEvents, and then when the client
connection dies, i am calling a rfbShutdownServer and
rfbScreenCleanup, but the malloc at rfbStatLookupEncoding isnt been
freed. So to free the stats i added a rfbResetStats(cl) after
rfbPrintStats(cl) at rfbClientConnectionGone in rfbserver.c before
free the cl pointer. (at rfbserver.c line 555). And this, obviously,
is correcting the memory leak. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

* rfb/rfbclient.h: Hopefully fix the crash when updating from 0.9.7
or earlier For backwards-compatibility reasons, we can only add struct members
to the end. That way, existing callers still can use newer
libraries, as the structs are always allocated by the library (and
therefore guaranteed to have the correct size) and still rely on the
same position of the parts the callers know about. Reported by Luca Falavigna. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

fail to detect it's html when it's ending in '.vnc' Also, remove superfluous #defines. We close the connection always.

code. Remove the UTF-8 encoding hack. This was really just an experiment. If the protocol passed in the handshake has "binary" then don't
base64 encode for the HyBi protocol. This will allow noVNC to
request the binary data be passed raw and not base64 encoded.
Unfortunately, the client doesn't speak first in VNC protocol (bad
original design). If it did then we could determine whether to
base64 encode or not based on the first HyBi frame from the client
and whether the binary bit is set or not. Oh well. Misc Cleanup: - Always free response and buf in handshake routine. - Remove some unused variables.

* libvncserver/rfbserver.c, libvncserver/websockets.c: websockets:
Add UTF-8 encoding support. This is not completely standard UTF-8 encoding. Only code points
0-255 are encoded and never encoded to more than two octets. Since
'\x00' is a WebSockets framing character, it's easier for all
parties to encode zero as '\xc4\x80', i.e. 194+128, i.e. UTF-8 256. This means that a random stream will be slightly more than 50%
larger using this encoding scheme. But it's easy CPU-wise for client
and server to decode/encode. This is especially important for
clients written in languages that have weak bitops, like Javascript
(i.e. the noVNC client). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
