2024-10-10drop obsolete HAVE_DIX_CONFIG_HEnrico Weigelt, metux IT consult2-4/+0
The symbol controls whether to include dix-config.h, and it's always set, thus we don't need it (and dozens of ifdef's) anymore. This commit only removes them from our own source files, where we can guarantee that dix-config.h is present - leaving the (potentially exported) headers untouched.

2017-04-26Add a Meson build system alongside autotools.Eric Anholt1-0/+10
This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest, and Xdmx so far. The outline of Xquartz/Xwin support is in tree, but hasn't been built yet. The unit tests are also not done. The intent is to build this as a complete replacement for the autotools system, then eventually replace autotools. meson is faster to generate the build, faster to run the bulid, shorter to write the build files in, and less error-prone than autotools. v2: Fix indentation nits, move version declaration to project(), use existing meson_options for version-config.h's vendor name/web.

2014-12-09dbe: Call to DDX SwapBuffers requires address of int, not unsigned int ↵Keith Packard1-2/+4
[CVE-2014-8097 pt. 2] When the local types used to walk the DBE request were changed, this changed the type of the parameter passed to the DDX SwapBuffers API, but there wasn't a matching change in the API definition. At this point, with the API frozen, I just stuck a new variable in with the correct type. Because we've already bounds-checked nStuff to be smaller than UINT32_MAX / sizeof(DbeSwapInfoRec), we know it will fit in a signed int without overflow.

2014-12-08dbe: unvalidated lengths in DbeSwapBuffers calls [CVE-2014-8097]Alan Coopersmith1-3/+8
ProcDbeSwapBuffers() has a 32bit (n) length value that it uses to read from a buffer. The length is never validated, which can lead to out of bound reads, and possibly returning the data read from out of bounds to the misbehaving client via an X Error packet. SProcDbeSwapBuffers() swaps data (for correct endianness) before handing it off to the real proc. While doing the swapping, the length field is not validated, which can cause memory corruption. v2: reorder checks to avoid compilers optimizing out checks for overflow that happen after we'd already have done the overflowing multiplications.

Compared to the patch that Daniel posted in January, I've added a few indent flags: -bap -psl -T PrivatePtr -T pmWait -T _XFUNCPROTOBEGIN -T _XFUNCPROTOEND -T _X_EXPORT The typedefs were needed to make the output of sdksyms.sh match the previous output, otherwise, the code is formatted badly enough that sdksyms.sh generates incorrect output. The generated code was compared with the previous version and found to be essentially identical -- "assert" line numbers and BUILD_TIME were the only differences found.

2010-06-02Fix pixmap validation in miDbePositionWindow.Aaron Plattner1-6/+14
miDbePositionWindow allocates two pixmaps: a front buffer, and a back buffer. If the buffers are supposed to be initialized, it validates a GC against the front buffer, then uses it to fill and/or copy both the front buffer *and* the back buffer, without revalidating. If the acceleration architecture needs different GC funcs for the two pixmaps -- for example if allocation of the front buffer exhausted video memory -- then this can cause crashes because the GC is not validated for the back buffer pixmap. Fix this by performing the rendering for the front buffer first, then revalidating against the back buffer before performing the back buffer rendering.
