-+ empty.
-+
-+nx-X11-3.3.0-1
-+
-+- Opened the 3.3.0 branch based on nx-X11-3.2.0-2.

-+
-+- Fix the NX_TRANS_WAKEUP stuff in WaitForSomething() to not over-
-+ ride a valid timeout.
-+
-+- Check if the requesting client is gone in the XFixes functions
-+ sending the cursor events.
-+
-+nx-X11-3.0.0-32
-+
-+- Define DDXOSVERRORF and DDXOSFATALERROR symbols on Sun.
-+
-+- Changed the copyright attribution from Medialogic to NoMachine.
-+
-+nx-X11-3.0.0-31
-+
-+- Make SmartScheduleStopTimer() visible outside Xserver/os/utils.c
-+ so that it can be called by the agent. Export the declaration in
-+ dixstruct.h.
-+
-+nx-X11-3.0.0-30
-+
-+- The OsVendorVErrorFFatal flag is set to 1 if the function pointed
-+ by OsVendorVErrorFProc is called due to a fatal error.
-+
-+- Give the possibility to the agent to redirect the standard error
-+ during a Popen() or a System() by setting the OsVendorStartRedir-
-+ ectErrorFProc and OsVendorEndRedirectErrorFProc function pointers.
-+
-+nx-X11-3.0.0-29
-+
-+- Changed the default message printed on a fatal server error. The
-+ new message is:
-+
-+ Error: Aborting session with 'Error text...'.
-+
-+- Hacked LogVWrite() to force all fatal error messages to have an
-+ uppercase initial. Also remove the trailing newline and the full-
-+ stop, if present.
-+
-+nx-X11-3.0.0-28
-+
-+- Corrected the typos in the ChangeLog.
-+
-+nx-X11-3.0.0-27
-+
-+- Fixed the cleanup of the X_RenderCompositeText16 padding bytes.
-+
-+- More code cleanup in the NX changes to the Xrender library.
-+
-+- Changed host.def to build the freetype and fontconfig libraries
-+ if the agent server is also built. Freetype is built as a shared
-+ library: this avoids the link error on 64 bit platforms.
-+
-+nx-X11-3.0.0-26
-+
-+- Applied the following security patches, from the X.Org security
-+ advisory, April 3rd, 2007 "Multiple vulnerability in X server,
-+ libXfont and libX11":
-+
-+ xorg-xserver-1.2.0-xcmisc.diff
-+ xorg-libXfont-1.2.7-bdf-fontdir.diff
-+ xorg-libX11-1.1.1-xinitimage.diff
-+
-+nx-X11-3.0.0-25
-+
-+- Added the missing *.X.original file for ChkIfEv.c and Xlib.h.
-+
-+nx-X11-3.0.0-24
-+
-+- Changed Xrender to clean up the padding bytes in XRenderComposite-
-+ Text functions.
-+
-+- Added function XRenderCleanGlyphs() cleaning the padding bytes in
-+ the data section of RenderAddGlyphs requests.
-+
-+nx-X11-3.0.0-23
-+
-+- Removed the additional parameter from the call to NXTransFlush()
-+ in _XReply().
-+
-+- Call NXTransExit() on AbortServer() (called by FatalError()) to
-+ give the proxy a chance to shut down the NX transport.
-+
-+nx-X11-3.0.0-22
-+
-+- Moved the replacement of XCheckIfEvent() ChkIfEv.c with the name
-+ XCheckIfEventNoFlush().
-+
-+nx-X11-3.0.0-21
-+
-+- Set BUFSIZE to 8192 bytes. While the output buffer size can be
-+ configured by setting the XLIBBUFFERSIZE in the environment (see
-+ OpenDis.c), this constant is still used when reading from the
-+ socket.
-+
-+nx-X11-3.0.0-20
-+
-+- If set, the handler pointed by _NXDisplayWriteFunction is called
-+ after that more data is written to the display connection.
-+
-+nx-X11-3.0.0-19
-+
-+- Added a RejectWellKnownSockets() stub to make possible to compile
-+ the agent when the NX transport is disabled.
-+
-+- Added more useful logs to _XWaitForWritable().
-+
-+nx-X11-3.0.0-18
-+
-+- Changed Imakefile of X11 and Xserver in order to build nxcompshad
-+ just before the NX agent server.
-+
-+- Changed Imakefile in Xserver to add NXdamage.o to NXAGENTOBJS.
-+
-+nx-X11-3.0.0-17
-+
-+- Changed host.def in order to build Xdamage and Xrandr libraries.
-+
-+- Changed host.def in order not to build NXWin.
-+
-+nx-X11-3.0.0-16
-+
-+- Changed host.def in order to build Xtst as a shared library.
-+
-+nx-X11-3.0.0-15
-+
-+- Changes to comply with nxcompshad library.
-+
-+- Changed configuration to statically build Xtst library.
-+
-+- Restored parser directory under Xserver/hw/xfree86.
-+
-+nx-X11-3.0.0-14
-+
-+- Changed the LICENSE file to state that the software is only made
-+ available under the version 2 of the GPL.
-+
-+- Added file COPYING.
-+
-+- In nx-X11/programs and nx-X11/programs/Xserver/hw/xfree86, removed
-+ files and directories not needed to build servers.
-+
-+nx-X11-3.0.0-13
-+
-+- Changes aimed to link servers with static versions of Xdmcp and Xau
-+ libraries.
-+
-+nx-X11-3.0.0-12
-+
-+- Added references to implented FR in the ChangeLog.
-+
-+- Removed nx-X11/fonts and nx-X11/doc directories. They are not needed
-+ for building the NX components.
-+
-+nx-X11-3.0.0-11
-+
-+- Updated the copyright notices to year 2007.
-+
-+nx-X11-3.0.0-10
-+
-+- Applied the following security patches:
-+
-+ x11r6.9.0-cidfonts.diff
-+ x11r6.9.0-dbe-render.diff
-+ x11r6.9.0-geteuid.diff
-+ x11r6.9.0-mitri.diff
-+ x11r6.9.0-setuid.diff
-+
-+nx-X11-3.0.0-9
-+
-+- Merged the NX changes to X11 with the X11R6.9.0 version of X.org.
-+
-+nx-X11-3.0.0-8
-+
-+- Changes to build Xshadow library when building X11.
-+
-+- Changes to Xserver Imakefile to link Xshadow library.
-+
-+- Changes to host.def in order to build on old distributions.
-+
-+nx-X11-3.0.0-7
-+
-+- Imported changes up to nx-X11-2.1.0-2
-+
-+- Fixed TR08D01485. Updated rgb file paths validation in order to
-+ support Ubuntu distribution.
-+
-+- Added Xtst to libraries to be linked by nxagent.
-+
-+- Changed Xpm Imakefile to build a shared library on Solaris.
-+
-+- Fixed build error on Solaris in xtrans.
-+
-+- Changed host.def not to build Xnest server.
-+
-+- Changed Xserver Imakefile to link nxaccess library.
-+
-+nx-X11-3.0.0-6
-+
-+- Added the path of nxaccess library to the server link command.
-+
-+nx-X11-3.0.0-5
-+
-+- Implemented FR10C01079 and FR10C01080. The merge of NX changes to
-+ the X.org code is complete.
-+
-+- Merged changes in config/cf. The NX-*.def files have been dismissed.
-+ Main platform dependent configurations have been moved to host.def.
-+
-+- Removed *.reference files from config/cf.
-+
-+- Fixed compilation for Cygwin platform.
-+
-+nx-X11-3.0.0-4
-+
-+- Imported all changes up to nx-X11-2.0.0-32.
-+
-+- Cleaned up lib/zlib directory.
-+
-+- Added missing file programs/Xserver/os/utils.c.NX.original.
-+
-+- Updated the copyright notice to year 2006.
-+
-+- The pointer to the display buffer is reset after an I/O error.
-+ This prevents leaving the buffer in an inconsistent state if the
-+ error occurs inside _XFlush().
-+
-+- Removed the modifications to the Xrender library. The cleanup of
-+ the padding bytes is now performed by the NX transport.
-+
-+- NX uses the updated ZLIB from its build tree, so Imake.tmpl will
-+ now assume that the platform as ZLIB unless otherwise stated.
-+
-+- The path of the SecurityPolicy file is searched and validated at
-+ runtime.
-+
-+- Added the _X11TransSocketProxyConnInfo() function to Xtranssock.c
-+ It returns the pointer to the XtransConnInfo private, if it is a
-+ valid _NXProxyConnInfo structure.
-+
-+- The above function is used by OpenDis.c to detect if the NX trans-
-+ port was requested on the display and avoid spurious error messa-
-+ ges in the case of a connection failure.
-+
-+- Added NXmiwindow.o to the NXAGENTOBJS in the Xserver's Imakefile
-+ and imported NXmiwindow.c in nxagent. This allows us to check the
-+ pointer to the pOldClip region in miSetShape() before going on
-+ freeing it.
-+
-+- The path of the XKB base directory and of the xkbcomp comand is
-+ validated at runtime.
-+
-+- Also added a check to verify the validity of the rgb file path.
-+
-+- Added NXresource.o to NXAGENTOBJS in the Imakefile of nxagent. We
-+ need this to a assign a resource to the pixmaps and other server
-+ objects which need to be enumerated at reconnection. Some objects,
-+ being created by the X server and not by the clients, don't pass
-+ through the resource assignment process operated by the dix. To
-+ ensure that all objects get a resource, we add a resource at the
-+ time the object is created and temporarily assign the resource to
-+ the server client. If the dix later assigns the resource to a va-
-+ lid client, the resource is removed from the server client's list.
-+
-+- The display block handler registered by the client is called in
-+ WaitForReadable() and WaitForWritable() before every select(),
-+ not only upon entering the function. The reason is that more
-+ data can be possibly produced for the NX link by the proxy it-
-+ self and, when setting the flush policy to deferred, the client
-+ may not have the chance of flushing the NX link.
-+
-+- Fixed a bug in XkbUseExtension() that caused Xlib to query the
-+ presence of the XKEYBOARD extension multiple times. This partial-
-+ ly implents the FR01D01275. The complete implementation required
-+ modifications to the X11 agent, implemented in nxagent-2.0.0-33.
-+
-+- Updated to comply with the new NXTransFlush() interface.
-+
-+- Both nxwin and nxagent now read the X authority file by using an
-+ fopen() instead of the system command 'cat'.
-+
-+- Removed NXmiwindow.o from the NXAGENTOBJ list. The agent will now
-+ use the original miwindow.c.
-+
-+- Added some additional logs in Xtranssock.c to follow the creation
-+ and removal of the X server's Unix listener.
-+
-+- Avoided the sleep of 5 seconds forced by Xtransutil.c if the dir-
-+ ectory where the Unix listener is created is not owned by root.
-+ This sleep is not executed on Cygwin (where the X socket can be
-+ hardly owned by root) but may delay the startup of the agent if
-+ the user chose a different NX_TEMP directory. Furthermore, it is
-+ unclear what real benefits such sleeps are intended to bring to
-+ the security of the X server. This can be controlled by defining
-+ the NX_TRANS_SLEEP directive in Xserver/os/Imakefile.
-+
-+- Added NXmiexpose.o to the NXAGENTOBJ.
-+
-+- Ensured that _X11TransSocketCloseConnInfo() now initiates the NX
-+ shutdown by calling NXTransClose().
-+
-+- Corrected a misplaced #else that made SocketUNIXConnect() skip a
-+ block if the connection was not to the NX transport.
-+
-+- Updated to comply with the new NX function prototypes introduced
-+ in nxcomp-2.0.0-31.
-+
-+- Moved the most important Xtranssock.c modifications into separate
-+ functions.
-+
-+- Ensured that the modifications enabling the internal connections
-+ to the proxy are compiled only when the TRANS_CLIENT directive is
-+ defined.
-+
-+- Solved a bug that prevented the X11 socket to be deleted at the X
-+ server shutdown. This needs further tests.
-+
-+- Added nxcompext to the link of nxagent, now that the dependency
-+ of libX11 from nxcompext is removed.
-+
-+- Improved the Xtranssock routines to never loop through the array
-+ of connection info.
-+
-+- Added a congestion flag to the connection info structure and a
-+ function querying the transport and reporting if a change in the
-+ congestion state has occurred. The code is currently not enabled,
-+ because instead of polling the transport, we let the proxy notify
-+ the changes in congestion state by using the callback. The code
-+ can be used in future to extend the library, for example, by add-
-+ ing some counters tracking the bandwidth usage of the socket con-
-+ nection, so that we can make the congestion notifications work
-+ even with a plain X11 connection.
-+
-+- Profiled the routines in XlibInt.c to reduce the number of calls
-+ to the error predicate function provided by the client.
-+
-+- Fixed the nxcompext build problem that caused make World to fail.
-+
-+- Added a 'CONF' target to the X11 and Xext Imakefiles so that the
-+ configure script is not run if the config.status exists.
-+
-+- Added the _NXDisplayBlockHandler hook. The function is called by
-+ Xlib before blocking. The parameter says if Xlib is going to wait
-+ for more input or because it needs to write to the display socket.
-+ The client can use the hook to perform any internal operation that
-+ may require some time to complete. The user, though, should not
-+ try to read or write to the display inside the callback routine.
-+
-+- Removed the outdated NX_TRANS_PROCESS, NX_TRANS_THREAD and NX_TR-
-+ ANS_INCLUDE defines.
-+
-+- Reverted the lib/Xext Imakefile to the original XF86 version and
-+ moved the build of the nxcompext library among the libX11 depend-
-+ encies.
-+
-+- Corrected the lib/X11 Imakefile so that a new build of nxcomp and
-+ nxcompext is not attempted if the libraries are up-to-date.
-+
-+- Removed the unused display buffer and image cleanup functions.
-+
-+- Reverted the PutImage.c file to the original XF86 version.
-+
-+- Added the _NXDisplayErrorPredicate function in XlibInt.c. It is
-+ actually a pointer to a function called whenever Xlib is going to
-+ perform a network operation. If the function returns true, the
-+ call will be aborted and Xlib will return the control to the ap-
-+ plication. It is up to the application to set the XlibDisplayIO-
-+ Error flag after the _NXDisplayErrorPredicate returns true. The
-+ function can be used to activate additional checks, besides the
-+ normal failures detected by Xlib on the display socket. For exam-
-+ ple, the application can set the funciton to verify if an inter-
-+ rupt was received or if any other event occurred mandating the
-+ end of the session.
-+
-+- Modified XIfEvent(), XMaskEvent() and XPeekIfEvent() to check the
-+ _NXDisplayErrorPredicate function and return immediately if the
-+ function returns true.
-+
-+- Modified _XWaitForReadable() to never enter the loop if the dis-
-+ play is broken.
-+
-+- Corrected a make problem on Windows that caused the nxcomp and
-+ nxcompext libraries to be referred with the wrong name, with the
-+ result that a new configure and make was attempted at each build
-+ attempt.
-+
-+- Merged all the changes to os, Xext, xkb, dix.
-+
-+- Changed host.def to build only the agent server.
-+
-+- Merged the changes to Xtranssock.c
-+
-+nx-X11-3.0.0-3
-+
-+- Merged the changes to lib/X11. Restored original PutImage.c and
-+ ClDisplay.c files.
-+
-+nx-X11-3.0.0-2
-+
-+- Created a directory named 'reference' to keep files that are chan-
-+ ged during the development of nx-X11 since the 1.5.0-16 to 2.0.0-32
-+ version. These files will be removed as long as the differences are
-+ merged to the 3.0.0 version. When all differences are merged, this
-+ directory will be removed.
-+
-+nx-X11-3.0.0-1
-+
-+- Opened the 3.0.0 branch based on the nx-X11-2.0.0-9. The 3.0.0
-+ branch will now support the migration toward the X.org tree. Due
-+ to time concerns, the 2.0.0 branch is going to be based on the
-+ same nx-X11 as the 1.5.0.
-+
-+nx-X11-2.0.0-9
-+
-+- Modified the agent link arguments to explicitly include the NX
-+ libraries.
-+
-+- Disabled the Xinerama extension to avoid further clashes with
-+ the redefinition of GC in Xlib.
-+
-+- Added os/libos.a at the end of the agent link.
-+
-+nx-X11-2.0.0-8
-+
-+- Moved the declarations of _NXEnable* and related structures from
-+ Xlibint.h to NXlibint.h.
-+
-+- Added provision for building the agent. This can be controlled by
-+ setting NXAgentServer to YES in host.def.
-+
-+- Setting the NXUpgradeAgentServer variable to YES in the host.def
-+ file will make the agent assume that it is being built in the new
-+ environment. This variable is normally unset when building in the
-+ 1.5.0 tree.
-+
-+nx-X11-2.0.0-7
-+
-+- Fixed a problem on AMD64 due to the size of the area pointed by
-+ the argument of _X11TransBytesReadable(). BytesReadable_t is long,
-+ at least on Linux, while the ioctl() requires a pointer to an int.
-+ The original _X11TransBytesReadable() function simply calls the
-+ ioctl() by passing the pointer that is provided. NXTransReadable(),
-+ instead, was correctly returning the value assuming a pointer to
-+ a long, but this crashes some applications, among them xterm. Now
-+ NXTransReadable() follows the same schema of the ioctl() call and
-+ stores the result assuming a pointer to an int.
-+
-+- Removed the outdated NX_TRANS_PROCESS and NX_TRANS_THREAD code.
-+
-+nx-X11-2.0.0-6
-+
-+- Made xterm work with the NX transport. This required small changes
-+ to the Xt toolkit's and the xterm's files to let them use the NX
-+ aware select(). This is useful to test the NX transport until the
-+ nxagent server is integrated.
-+
-+- When the transport is gone _X11TransSocketBytesReadable() returns
-+ EPIPE. This makes the client become aware of the closure of the
-+ connection.
-+
-+- Added a call to NXTransDestroy() in XCloseDisplay().
-+
-+- The exit() function in XlibInt.c causes a call to NXTransExit().
-+
-+- Merged changes to dix/pixmap.c, xkb/xkbDflts.h, mi/Imakefile.
-+
-+- Removed unneeded changes and files containing patches already in
-+ the latest X.org distribution: dix/dispatch.c, fb/fbcompose.c, fb/
-+ fbgc.c, xkb/ddxList.c, font/fontfile/dirfile.c, font/fontfile/
-+ encparse.c, font/fontfile/fontfile.c, font/FreeType/fttools.c,
-+ Xrender/FillRect.c, Xrender/Picture.c.
-+
-+nx-X11-2.0.0-5
-+
-+- Changes to the lib/X11/Imakefile to cleanly build the tree. This
-+ is obtained by creating a link to the Xcomp library in exports/lib
-+ without having to modify the programs' Imakefiles.
-+
-+- Finished merging the NX changes in the lib/X11 files.
-+
-+- Merged the CHANGELOG with the one from the 1.5.0 tree.
-+
-+nx-X11-2.0.0-4
-+
-+- Merged the NX changes in most Xtrans and lib/X11 files.
-+
-+nx-X11-2.0.0-3
-+
-+- Temporarily disabled the use of the MMX extensions in the Xserver's
-+ fb code to successfully compile with GCC 4.
-+
-+nx-X11-2.0.0-2
-+
-+- Imported the *.NX.reference and *.XF86.reference files that will
-+ be needed for the merge. These files are the *.original from the
-+ 1.5.0 tree. They will be removed as long as the merge advances.
-+
-+nx-X11-2.0.0-1
-+
-+- Created the 2.0.0 branch based on X.org the 6.8.99.16 snapshot.
-+
-+nx-X11-1.5.0-16
-+
-+- Added the missing *.XF86.original and *.NX.original files.
-+
-+nx-X11-1.5.0-15
-+
-+- Made the nxagent server use select() instead of poll() on Solaris
-+ so that it can leverage the new NX transport.
-+
-+- Moved the NXTransFlush() call to _XReply().
-+
-+nx-X11-1.5.0-14
-+
-+- Added the 'synchronous' parameter in the _XWaitForReadable() call
-+ to NXTransFlush().
-+
-+nx-X11-1.5.0-13
-+
-+- Removed the log entry in XlibInt.c on calling the NXTransFlush().
-+
-+nx-X11-1.5.0-12
-+
-+- Changed XlibInt.c and utils.c to call NXTransExit().
-+
-+nx-X11-1.5.0-11
-+
-+- Changed XlibInt.c to comply with the new NXTransFlush() interfa-
-+ ce introduced in nxcomp-1.5.0-42.
-+
-+- Cosmetic changes to messages printed for debug.
-+
-+nx-X11-1.5.0-10
-+
-+- Ensured that all calls to _XIOError() are followed by a return.
-+
-+- Put exiting the client program in the case of an I/O error under
-+ the control of the _NXContinueOnDisplayError flag. If set, the
-+ I/O error routine will simply return, leaving to the application
-+ the responsibility of checking the state of the XlibDisplayIOEr-
-+ ror flag.
-+
-+- Added some checks whenever a read or write is performed on the X
-+ connection, so that we can exit the I/O loop if the X channel is
-+ gone. It is likely that more work will be needed when trying to
-+ support XTHREADS enabled connections. This should not be a pro-
-+ blem for now, as the default is still to quit the application un-
-+ less the _NXContinueOnDisplayError flag is explicitly set.
-+
-+nx-X11-1.5.0-9
-+
-+- Removed the references to the cygipc library in NXWin. Now use the
-+ cygserver daemon to provide the MIT-SHM extension.
-+
-+- Fixed an error in the UseCygIPC definition.
-+
-+- Changed the cygwin.cf file to avoid redefinition of the BuildGlxExt,
-+ XWinServer and BuildGlxExt symbols.
-+
-+nx-X11-1.5.0-8
-+
-+- Added provision for deferred writes in the NX transport. When en-
-+ tering _XWaitForReadable() we must ensure that data is flushed to
-+ the proxy link.
-+
-+- Added the UseCygIPC define to NX-Cygwin.def.
-+
-+- Updated the NoMachine copyright notice on the modified files.
-+
-+nx-X11-1.5.0-7
-+
-+- Added the GLX extension in NX-Sun.def.
-+
-+- Added some more logs in WaitFor.c.
-+
-+nx-X11-1.5.0-6
-+
-+- Modified Xlibint.h and XlibInt.c to remove the _NXFlushSize para-
-+ meter. New agents run the NX transport in-process, so we don't get
-+ any benefit from increasing the display buffer size.
-+
-+- Modified NX-Darwin.def to not build the NXDarwin server. Since the
-+ 1.4.0 version the NXDarwin server is unsupported and the NX client
-+ for the Mac requires that the Apple X server is installed.
-+
-+- Changed NX-Linux.def to avoid the warning due to "SharedLibGLw"
-+ being not defined.
-+
-+nx-X11-1.5.0-5
-+
-+- Modified the Xserver Imakefile to link nxagent with FbPostFbLibs
-+ and avoid including mfb/libmfb.a.
-+
-+- Added the GLX extension in NX-Linux.def. This provides unaccelera-
-+ ted support in nxagent, with GLX operations translated into core X
-+ protocol primitives.
-+
-+- Fixed x-X11/programs/Xserver/GL/dri/Imakefile to look in ../../hw/
-+ /xfree86/os-support/bus for includes.
-+
-+nx-X11-1.5.0-4
-+
-+- Avoid calling NXTransSelect() if the transport is gone, so that we
-+ don't have to wait until the timeout.
-+
-+- Added the "-fno-strict-aliasing" option to linux.cf when compiling
-+ with a GCC version >= 4. In the words of Stefan Dirsch: "The opt-
-+ ion, which is default since gcc 3.1, can result in wrong code when
-+ the gcc warnings related to it are ignored. And as there are seve-
-+ ral warnings in X11 related to it, it has been disabled for X11
-+ from the beginning. This didn't change for gcc4, so it still needs
-+ to be used."
-+
-+- Added more logs in XlibInt.c and utils.c. A warning is printed if
-+ the SmartScheduler is initialized.
-+
-+nx-X11-1.5.0-3
-+
-+- Started integration of nxcomp with the X libraries. The Xtrans
-+ code creates an internal connection to the nxcomp library instead
-+ of a child proxy process.
-+
-+- Changed Xpoll.h and XlibInt.c to replace the standard Select
-+ with a version giving NX a chance to check its own descriptors.
-+
-+- Implemented the NXTransReadVector() and the NXTransWriteVector()
-+ functions to replace READV() and WRITEV().
-+
-+- Implemented memory-to-memory communication with the NX proxy by
-+ making use of the NXTransAgent() interface.
-+
-+nx-X11-1.5.0-2
-+
-+- We think that the way LoadAuthorization() is working is wrong.
-+ It doesn't reset the list of stored authorizations before reading
-+ the new cookies. Our take is that if a new auth file is to be
-+ read, the only cookies that are to be accepted are those that are
-+ in the new file, not those in the file -plus- those that have
-+ been in the file in the past. Furthermore, if the list can't be
-+ read or it is empty, it should assume that it ignores which co-
-+ okies are valid and thus it should disable any access. Your mile-
-+ age can vary. A less draconian approach could be to leave the old
-+ cookies if the file can't be read and remove them only if the
-+ file is empty.
-+
-+ Adding the cookies without removing the old values for the same
-+ protocol has an important implication. If an user shares the co-
-+ okie with somebody and later wants to revoke the access to the
-+ display, changing the cookie will not work. This is especially
-+ important with NX. For security reasons, after reconnecting the
-+ session to a different display, it is advisable to generate a
-+ new set of cookies, but doing that it is useless with the current
-+ code, as the old cookies are going to be still accepted. On the
-+ same topic, consider that once an user has got access to the X
-+ server, he/she can freely enable host authentication from any
-+ host, so the safe behaviour should be to reset the host based
-+ authenthication at least at reconnection, and keep as valid only
-+ the cookies that are actually in the file. This behaviour would
-+ surely break many applications, among them a SSH connection run
-+ inside a NX session, as ssh -X reads the cookie for the display
-+ only at session startup and does not read the cookies again
-+ when the auth file is changed.
-+
-+ Another bug (or feature, depending on how you want to consider
-+ it) is that if the authority file contains entries for different
-+ displays (as it is the norm when the authority file is the default
-+ .Xauthority in the user's home), the X server will match -any- of
-+ the cookies, even cookies that are not for its own display. This
-+ means that you have to be careful when passing an authority file
-+ to nxagent and maybe keep separate files for letting nxagent find
-+ the cookie to be used to connect to the remote display and for
-+ letting it find what cookies to accept. If the file is the same,
-+ clients will be able to connect to nxagent with both the cookies.
-+ This bug obviously affects any X server, also the real X server
-+ running on the workstation, so it is common to see nxagent being
-+ able to connect to the X server even if no cookie matches the
-+ real display.
-+
-+- Added a check in lib/Xau/AuRead.c to prevent the fread() call to
-+ be interrupted by SIGCHLD while reading the auth file. Due to the
-+ way the old code worked, this could lead to the server enabling
-+ local host access to the display. This problem had been identified
-+ in the past. We just found that all the code dealing with reading
-+ the auth file was affected. The code calls sigprocmask() to block
-+ the signal (though it leaves some other calls unprotected) but the
-+ SIGCHLD was not included in the set.
-+
-+- Added SIGCHLD to the set of signals that are blocked when reading
-+ the authorization file.
-+
-+- As I was at it, I changed the path to the SecurityPolicy file. A
-+ few Linux ditributors ship the file in $LIBDIR/xserver, a few only
-+ in /etc/X11/xserver, most others in both places. It seems that
-+ those who ship in $LIBDIR/xserver do also in /etc/X11 but the op-
-+ posite is not true, so I switched to /etc/X11.
-+
-+nx-X11-1.5.0-1
-+
-+- Opened the 1.5.0 branch.
-+
-+nx-X11-1.4.1-2
-+
-+- Set parameter UseCygIPC on cygwin conf file in order to force the
-+ build of MIT-SHM estension.
-+
-+- Removed some spurius object file.
-+
-+nx-X11-1.4.1-1
-+
-+- Opened the 1.4.1 branch.
-+
-+nx-X11-1.4.0-8
-+
-+- Changed DefaultFontPath and DefaultRGBDatabase in
-+ NX-Cygwin.def.
-+
-+nx-X11-1.4.0-7
-+
-+- Imported dispatch in nxdarwin package, in order to let
-+ nxdarwin being able to detect new client connection.
-+
-+- Changed the Xpm Imakefile to make also .a static library
-+ on Solaris. To link nxviewer and nxdestkop staticaly.
-+
-+nx-X11-1.4.0-6
-+
-+- XInput extension enabled on MacOSX.
-+
-+- Added some missing backup files of the original XFree86
-+ package.
-+
-+nx-X11-1.4.0-5
-+
-+- Changed the mi Imakefile in order to let xfree86 servers use
-+ the normal mi extension initialization for the XInput exten-
-+ sion.
-+
-+- XInput extension enabled on Solaris.
-+
-+nx-X11-1.4.0-4
-+
-+- Removed the RejectWellKnownSocket for the cygwin and
-+ MacOSX environments that doesn't use the Xtransport library.
-+
-+nx-X11-1.4.0-3
-+
-+- Changed the implementation of the reject method in the
-+ Xtransport library, now close any new incoming connection
-+ immediately without reading or writing to it.
-+
-+nx-X11-1.4.0-2
-+
-+- Implemented a reject method in the Xtransport library,
-+ this function accept and close every connection attempt,
-+ on the specified listening socket.
-+
-+- Added the new function RejectWellKnownSocket to the os
-+ connection code.
-+ This function use the new transport reject function on
-+ all listening socket.
-+
-+nx-X11-1.4.0-1
-+
-+- Opened the 1.4.0 branch.
-+
-+- Removed forgotten nxagent-1.3.2-20 directory.
-+
-+nx-X11-1.3.2-9
-+
-+- Prevents NX Darwin server going through the reset. On Darwin
-+ we found that the it is not possible to get the correct key-
-+ board layout unless it is set on the local machine, before
-+ the NX session is started, by using xmodmap. As we set the
-+ keyboard locally, we must prevent the X server to reset, or
-+ we would loose any local configuration.
-+
-+nx-X11-1.3.2-8
-+
-+- Removed action associated to keysym XK_Terminate_Server. This
-+ could cause agent to be terminated when pressing shift + back-
-+ space if using the default US keyboard mapping.
-+
-+- Disabled the remaining debug logs in lib/X11/PutImage.c
-+
-+nx-X11-1.3.2-7
-+
-+- Fixed the wrong programs/Xserver/Imakefile in 1.3.2-6 package.
-+
-+nx-X11-1.3.2-6
-+
-+- Changed the define from NX_CLEAN_IN_PLACE to NX_CLEAN_INPLACE.
-+ Definition of symbol is now placed in the Imakefile.
-+
-+- The new _NXEnableCleanInplace Xlib variable does control which
-+ algorithm is used to clean the images. Setting NX_IMAGEINPLACE
-+ in the environment will activate the in-place cleanup.
-+
-+- The default value of _NXEnableCleanInplace is -1. Leaving it to
-+ a value <= 0 disables use of CleanInplace.
-+
-+nx-X11-1.3.2-5
-+
-+- Patch in config/cf/sun.cf. Fix for libfontconfig compilation
-+ during gmake Everything on Solaris.
-+
-+- Patch in lib/X11/Imakefile. Fix for nxcomp compilation during
-+ gmake World on Solaris.
-+
-+nx-X11-1.3.2-4
-+
-+- Image cleanup is now performed by using NXCleanInPlaceImage from
-+ nxcompext. This function saves a buffer copy by cleaning the
-+ padding bytes in the same buffer provided by the caller. Note that
-+ to prevent memory violations in the case the image was allocated
-+ in a static buffer, the function will temporarily redefine the
-+ SIGSEGV handler. The former handler is restored before returning
-+ to the caller. This can potentially affect some multithreaded
-+ clients. Is to be decided if the function is safe enough to be
-+ included in the production release.
-+
-+nx-X11-1.3.2-3
-+
-+- More debug logs in programs/Xserver/xkb/ddxLoad.c.
-+
-+nx-X11-1.3.2-2
-+
-+- Added NXmiwindow.o to NXAGENTOBJS in programs/Xserver/Imakefile.
-+ File was not linked into the resulting nxagent. This solves the
-+ problem of missing repaints in CDE and other Xt applications.
-+
-+nx-X11-1.3.2-1
-+
-+- Added some debug logs in programs/Xserver/xkb/ddxLoad.c. Function
-+ XkbDDXCompileKeymapByNames is called by OpenOffice to read the
-+ keyboard configuration whenever a drop-down menu is accessed. It
-+ seem to always fail with the following error:
-+
-+ The XKEYBOARD keymap compiler (xkbcomp) reports:
-+ > Error: Can't find file "unknown" for geometry include
-+ > Exiting
-+ > Abandoning geometry file "default"
-+
-+- Opened the 1.3.2 development branch.
-+
-+nx-X11-1.3.1-12
-+
-+- Fixed a problem in xkb/ddxLoad.c on Solaris where Pclose was
-+ always returning an error code despite the fact that command
-+ was executed properly.
-+
-+nx-X11-1.3.1-11
-+
-+- Changed default GCC flags from '-O2 -fno-strength-reduce' to
-+ -O3. No platform where NX is targeted is currently using a
-+ GCC 2.x affected by the -fno-strength-reduce bug. Note also
-+ that nxcomp is already compiled with -O3 since 1.1.1, so it
-+ can be considered safe.
-+
-+nx-X11-1.3.1-10
-+
-+- Imported an updated fbcompose.c file from XFree86-4.3.99.902.
-+ This fixes "uninitialized value" problems reported by Valgrind.
-+
-+- Fixed further buffer overflows by updating the following file
-+ with recent versions coming from the XFree86-4.3.99.902 tree.
-+
-+ nx-X11/lib/font/fontfile/dirfile.c
-+ nx-X11/lib/font/fontfile/encparse.c
-+ nx-X11/lib/font/fontfile/fontfile.c
-+
-+- Fixed a possible buffer overflow in lib/font/FreeType/fttools.c.
-+ Verified that the change is already in the XFree86 4.4.0 CVS.
-+
-+nx-X11-1.3.1-9
-+
-+- Fixed Xserver/Imakefile which was still referencing NXpixmap.o.
-+
-+nx-X11-1.3.1-8
-+
-+- Imported an updated fbgc.c from XFree86-4.3.99.902. This fixes
-+ some minor problems reported by Valgrind.
-+
-+- A major problem was reported by Valgrind about reading after
-+ the block allocated in fbCreatePixmap from AllocatePixmap. The
-+ file pixmap.c has been modified so that 4 bytes are added to
-+ the pixmap buffer at any new allocation. This quick hack should
-+ solve the problem for both nxagent and the NXWin server. Further
-+ investigation is planned for the next release.
-+
-+- Fixed Xtranssock.c to compile on Solaris where struct sigaction
-+ doesn't have the sa_restorer member.
-+
-+nx-X11-1.3.1-5
-+
-+- Renamed the NX-sun.def configuration file to NX-Sun.def.
-+
-+- Renamed the non-standard NX_iPAQ_XServer and NX_Zaurus_XServer
-+ symbols to NXiPAQXServer and NXZaurusXServer.
-+
-+- Added the missing sun.cf.XF86.original file in config/cf.
-+
-+- Added the missing empty file host.def.XF86.original in the
-+ same directory.
-+
-+- Added initialization of sa.sa_mask when setting sigaction()
-+ for SIGCHLD. The problem was reported by Valgrind running
-+ nxagent.
-+
-+- Removed an unused block of code from WaitFor.c. The code had
-+ been commented out in previous versions.
-+
-+- Removed the non-standard colon at the end of version in this
-+ CHANGELOG.
-+
-+- Removed the spurious spaces in this CHANGELOG.
-+
-+nx-X11-1.3.1-4
-+
-+- Added a little workaround to the top Imakefile intended to
-+ hide the makedepend warnings about non portable whitespaces
-+ in sources.
-+
-+nx-X11-1.3.1-3
-+
-+- Fixed compilation problem with nxagent-1.3.1-13.
-+
-+nx-X11-1.3.1-2
-+
-+- Changes in NX-sun.def configuration file for Solaris to allow
-+ compilation of the XKB extension.
-+
-+nx-X11-1.3.1-1
-+
-+- Opened the 1.3.1 development branch.
-+
-+nx-X11-1.3.0-6
-+
-+- Original output buffer size in stock XFree86 is 2048. We try
-+ to reduce context switches and help stream compression by
-+ increasing the maximum size of the buffer 8192. _NXFlushSize
-+ determines when the display buffer is actually flushed. It is
-+ set by default to 4096 but agents should set it to 0 if they
-+ want to disable early flush.
-+
-+- Added the _NXLostSequenceFunction function pointer to let NX
-+ agents suppress the error message and modify the default Xlib
-+ behaviour when out-of-order sequence numbers are received.
