This is an automated email from the git hooks/post-receive script. x2go pushed a commit to branch 3.6.x in repository nx-libs. commit 1e5ee575d4912665dd2356681f0827d5229fa1f5 Author: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> Date: Fri Feb 13 14:14:26 2015 +0100 nx-X11 vs. X.Org 6.9 patches for further studying / documentation NoMachine kept all original X.Org 6.9 files in the nx-X11 source tree. These files have been removed in Feb 2015 during a major code cleanup. For later studying we provide all diffs of the changes that NoMachine employed on the original X.Org X11 code tree in the doc/nx-X11_vs_XOrg69_patches folder. ---

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. diff --git a/doc/nx-X11_vs_XOrg69_patches/ChkIfEv.c.NX.patch b/doc/nx-X11_vs_XOrg69_patches/ChkIfEv.c.NX.patch new file mode 100644 index 0000000..333838d --- /dev/null +++ b/doc/nx-X11_vs_XOrg69_patches/ChkIfEv.c.NX.patch @@ -0,0 +1,59 @@ +--- ./nx-X11/lib/X11/ChkIfEv.c.X.original 2015-02-13 14:03:44.620443950 +0100 ++++ ./nx-X11/lib/X11/ChkIfEv.c 2015-02-10 19:13:13.120711494 +0100 +@@ -83,3 +83,56 @@ + UnlockDisplay(dpy); + return False; + } ++ ++#ifdef NX_TRANS_SOCKET ++ ++/* ++ * This is just like XCheckIfEvent() but doesn't ++ * flush the output buffer if it can't read new ++ * events. ++ */ ++ ++Bool XCheckIfEventNoFlush (dpy, event, predicate, arg) ++ register Display *dpy; ++ Bool (*predicate)( ++ Display* /* display */, ++ XEvent* /* event */, ++ char* /* arg */ ++ ); /* function to call */ ++ register XEvent *event; /* XEvent to be filled in. */ ++ char *arg; ++{ ++ register _XQEvent *prev, *qelt; ++ unsigned long qe_serial = 0; ++ int n; /* time through count */ ++ ++ LockDisplay(dpy); ++ prev = NULL; ++ for (n = 2; --n >= 0;) { ++ for (qelt = prev ? prev->next : dpy->head; ++ qelt; ++ prev = qelt, qelt = qelt->next) { ++ if(qelt->qserial_num > qe_serial ++ && (*predicate)(dpy, &qelt->event, arg)) { ++ *event = qelt->event; ++ _XDeq(dpy, prev, qelt); ++ UnlockDisplay(dpy); ++ return True; ++ } ++ } ++ if (prev) ++ qe_serial = prev->qserial_num; ++ switch (n) { ++ case 1: ++ _XEventsQueued(dpy, QueuedAfterReading); ++ break; ++ } ++ if (prev && prev->qserial_num != qe_serial) ++ /* another thread has snatched this event */ ++ prev = NULL; ++ } ++ UnlockDisplay(dpy); ++ return False; ++} ++ ++#endif diff --git a/doc/nx-X11_vs_XOrg69_patches/ConnDis.c.NX.patch b/doc/nx-X11_vs_XOrg69_patches/ConnDis.c.NX.patch new file mode 100644 index 0000000..17f0549 --- /dev/null +++ b/doc/nx-X11_vs_XOrg69_patches/ConnDis.c.NX.patch @@ -0,0 +1,319 @@ +--- ./nx-X11/lib/X11/ConnDis.c.X.original 2015-02-13 14:03:44.620443950 +0100 ++++ ./nx-X11/lib/X11/ConnDis.c 2015-02-10 19:13:13.008715687 +0100 +@@ -25,6 +25,24 @@ + in this Software without prior written authorization from The Open Group. + + */ ++ ++/**************************************************************************/ ++/* */ ++/* Copyright (c) 2001, 2011 NoMachine, http://www.nomachine.com/. */ ++/* */ ++/* NX-X11, NX protocol compression and NX extensions to this software */ ++/* are copyright of NoMachine.

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.

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 server will match -any- of ++ * the cookies, even cookies that are not for its own display. This ++ * means that you have be careful when passing an authority file to ++ * nxagent or Xnest 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.

It does this by starting with a 64 byte buffer. If that size limit is hit, it does a realloc of the buffer size << 1, basically doubling the needed length every time the length limit is hit. Eventually, this will shift out to 0 (for a length of ~4gig), and that length will be passed on to realloc(). A length of 0 (with a valid pointer) causes realloc to free the buffer on most POSIX platforms, but the caller will still have a pointer to it, leading to use after free issues. --- nx-X11/lib/font/fontfile/dirfile.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/nx-X11/lib/font/fontfile/dirfile.c b/nx-X11/lib/font/fontfile/dirfile.c index f390391..3a2fead 100644 --- a/nx-X11/lib/font/fontfile/dirfile.c +++ b/nx-X11/lib/font/fontfile/dirfile.c @@ -45,6 +45,7 @@ in this Software without prior written authorization from The Open Group. #include <sys/types.h> #include <sys/stat.h> #include <errno.h> +#include <limits.h> static Bool AddFileNameAliases ( FontDirectoryPtr dir ); static int ReadFontAlias ( char *directory, Bool isFile, @@ -373,6 +374,9 @@ lexAlias(FILE *file, char **lexToken) int nsize; char *nbuf; + if (tokenSize >= (INT_MAX >> 2)) + /* Stop before we overflow */ + return EALLOC; nsize = tokenSize ?

If that size was bigger than the current reply buffer size, _fs_start_read would add it to the existing buffer size plus the buffer size increment constant and realloc the buffer to that result. This math could overflow, causing the code to allocate a smaller buffer than the amount it was about to read into that buffer from the network. It could also succeed, allowing the remote font server to cause massive allocations in the X server, possibly using up all the address space in a 32-bit X server, allowing the triggering of other bugs in code that fails to handle malloc failure properly.
