Instead, now it always register all "font path element" backends, and adds built-ins fonts at the end of the default font path. This should be a more reasonable solution, to "correct" the most common Xorg FAQ (could not open default font 'fixed'), and also don't break by default applications that use only the standard/historical X Font rendering.

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-5/+5
| | | | | | | | | | | | | | | | | | | | 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/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)

* NXAGENT_UPGRADE code cleanup:Mike Gabriel2015-04-161-177/+99
| | | | | | | | | | | 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).
