* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-2829-70/+435
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.
* Replace 'pointer' type with 'void *'Keith Packard2015-12-2843-305/+305
| | | | | | | | | | This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer' is used throughout the X server for other things, and having duplicate names generates compiler warnings.

|/ | | | | | | | | | | | | | | xorg-server does not follow the convention of using 2 dashes. Note that --help does produce the help output. However, it produces this additional output after it: Error: Aborting session with 'Unrecognized option: --help'. Session: Aborting session at 'Sun Jun 28 01:35:35 2015'. Session: Session aborted at 'Sun Jun 28 01:35:35 2015'. It also causes a return code of 1 rather than 0. Therefore, we should instruct users to call -help instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ProcPutImage() calculates a length field from a width, left pad and depth specified by the client (if the specified format is XYPixmap). The calculations for the total amount of memory the server needs for the pixmap can overflow a 32-bit number, causing out-of-bounds memory writes on 32-bit systems (since the length is stored in a long int variable). v2: backport to nx-libs 3.6.x (Mike DePaulo) v3: port to NXdispatch.c rather than dispatch.c (Mike DePaulo) Reported-by: Ilja Van Sprundel <ivansprundel@ioactive.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Conflicts: dix/dispatch.c

|/ | | | | | | | | | | | | | | | | | | | | | | xorg/Xserver http://lists.x.org/archives/xorg-announce/2013-October/002332.html Save a pointer to the passed in closure structure before copying it and overwriting the *c pointer to point to our copy instead of the original. If we hit an error, once we free(c), reset c to point to the original structure before jumping to the cleanup code that references *c. Since one of the errors being checked for is whether the server was able to malloc(c->nChars * itemSize), the client can potentially pass a number of characters chosen to cause the malloc to fail and the error path to be taken, resulting in the read from freed memory. Since the memory is accessed almost immediately afterwards, and the X server is mostly single threaded, the odds of the free memory having invalid contents are low with most malloc implementations when not using memory debugging features, but some allocators will definitely overwrite the memory there, leading to a likely crash. v2: Apply to NXdixfonts.c rather than dixfonts.c (Mike DePaulo)

| | | | | | | | | | | NX agent contains/ed two build trees. An old one (probably pre-3.x.y) and a "newer" one. The "newer" code tree used to become enabled by setting NXUpgradeAgentServer in nx-X11/config/cf/host.def to YES. As building the NXUpgradeAgentServer has been the default for years now, we drop all code that does not get used at build time for NXUpgradeAgentServer == YES (i.e., the code that belongs to the pre-3.x.y phase of NX agent).

(2) In nx-X11/programs/Xserver/hw/nxagent/Render.c: Check for pSrc->pDrawable to exist instead of having nxagent segfault when it does not. This enables the possibility of compiling all nxagent modules in TEST mode.

| | | | | | | | | | | | | | (320_nxagent_configurable-keystrokes.full.patch). Replaces the hardcoded nxagent keybindings by a configurable table of keybindings. The default configuration is the same as the original one, to maintain compatibility. A user/administrator can either specify a command line parameter, environment variable or place a file in ~/.nx/config/keystrokes.cfg or /etc/nxagent/keystrokes.cfg to reconfigure these keybindings. The configuration file format is XML, a dependency on libxml2 is added to allow parsing the configuration.

* Avoid large pixmaps (110_nxagent_createpixmap-bounds-check.full.patch).Mike Gabriel2015-02-101-0/+17
| | | | | | | | | | | | | | | | | It is allowed to try and allocate a pixmap which is larger than 32767 in either dimension. However, all of the framebuffer code is buggy and does not reliably draw to such big pixmaps, basically because the Region data structure operates with signed shorts for the rectangles in it. Furthermore, several places in the X server computes the size in bytes of the pixmap and tries to store it in an integer. This integer can overflow and cause the allocated size to be much smaller. So, such big pixmaps are rejected here with a BadAlloc Originally contributed by FreeNX Team

* Create Windows and fix drawing issues on Big Endian 64bit systems ↵Mihai Moldovan2015-02-102-4/+16
| | | | | | | | | | | | | | | | | | | (057_nx-X11_sanitize-eventmasks.full.patch). Multiple endiannes issues were setting incorrect event masks when creating and drawing X11 windows. This time, a smaller integer has been casted to a bigger one and passed to some function actually setting its value. This meant, that garbage from stack was attached to the smaller integer value, putting unknown memory into the lower bytes of the bigger integer. Fix this by creating a big, initialized temporary variable, let the function do its magic on that one and pass the value back to the smaller variable--and cross your fingers the smaller variable can hold it without overrunning. (The last bit is a design issue we can't really fix and has been around even before this patch.)
