* pointer typedef in Xdefs.h: Define pointer type for building against older ↵Mike Gabriel2015-12-281-2/+8
| | | | Xlib versions that still expect the pointer type to exist (e.g. Ubuntu <= 14.04, Debian <= 7.0).
* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-28235-756/+1121
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | xorg-server does not follow the convention of using 2 dashes. Note that --help does produce the help output.

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.

| | | | | | | | | | | | The client-side library libNX_GL.{a,so} is not built when building nx-libs. However, nx-X11/lib/GL/** ships several imake include files (Imakefile.inc) that are also used in nx-X11/programs/Xserver/GL/**. These files have been moved from the nx-X11/lib/GL/ code subtree to the nx-X11/programs/Xserver/GL/. Furthermore, we don't provide module builds of the GL extension anymore, as that feature is neither used in nx-libs.

|/ | | | | | | | | | | | | | | | | | | | | | | 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)

It makes sure that for source pictures, which do not have a drawable surface, a filter is selected that is supported on the "main" and all other screens. Alternatively, if the requested filter is not available on all screens and the picture is a source picture, this function fails gracefully. Additionally, the ChangePictureFilter hook is now called for non-source pictures. This also needs an implementation in mipict.{c,h}. The default hook does nothing and returns a success value.
