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. |
