XFree86 18.104.22.168 (XX Xxxxxxxx 200X) XFree86 22.214.171.124 (29 February 2004) 723. Some more font path checks. 722. Fix font alias overrun. 721. Fix problems with earlier fix (713 below) to intermittent XDarwin crash when changing cursors with dual processors (Torrey T. Lyons). XFree86 126.96.36.199 (18 October 2002) 720. Fix black cursor images on Mac OS X 10.2.2 (Joseph Maurer). 719. Fix XDarwin rootless crash when window resizing with complex bit gravity (Greg Parker). 718. Xdm patches: realloc usage, zero malloc()ated memory, enable /dev/urandom on NetBSD 1.4 and later (#5345, Mike A. Harris, #5401, Matthias Scheler) 717. [SECURITY] Implement LocalClientCred() to return the credentials of local clients connected through Unix domain sockets on systems that have the required support (for now recent Linux, FreeBSD >= 4.6, OpenBSD >= 3.0 are implemented), and use that in ShmAttach() to grant access to the client. When client credentials are not available, require world accessibility. (Matthieu Herrb). 716. BIOSDisplay was always getting forced to R128_BIOS_DISPLAY_FP on cards that might have a FP attached. This was wrong if a CRT is being used instead, and caused both sets of DPMS routines to get used, which resulted in a SEGV on CloseDisplay(), as well as making DPMS not work for a CRT (Stuart Anderson). XFree86 4.2.1 (03 September 2002) 715. [SECURITY] Fix an Xlib problem that made it possible to load arbitrary code into privileged clients. 714. Fix i810_free_page() and i830_free_page() for DRI kernel modules so that later 2.4.x kernels are supported. XFree86 188.8.131.52 (21 August 2002) 713. Fix intermittent XDarwin crash when changing cursors on dual processor machines (Torrey T. Lyons). 712. Fix Finder warnings about XDarwin plist format on Jaguar (Torrey T. Lyons). 711. Fix XDarwin build issues on Jaguar (Sean Fagan). 710. When using the vesa driver and the DisplaySize option the server would crash with a floating point exception due to a divide by zero in miscreeninit() (#5298, Mike A. Harris). 709. Updated patch from head to fix problem described in #5244 (freed memory being deref'd in xaw) (email@example.com) 708. The function MoveLine in lib/Xaw/TextAction.c sometimes attempts to read uninitialized memory when hit ctrl-N in a Text widget to move to the next line (#5245, Johnathan Kamens). 707. Close XDarwin rootless windows properly for Jaguar compatibility (Greg Parker). 706. Build libXt as a flat namespace image on Darwin (Torrey T. Lyons). 705.

Fix a problem related to reserving the overlay key in the default colormap in 24+8 mode. This caused some clients using the 8-bit visuals to fail (David Dawes). 701.

Fix an unresolved symbol in libGLU.so that shows up when building it with gcc-3 (David Dawes). 693. Fix incorrect symbol prefixing with Xlib's i18n modules on Solaris, and fix invalid code caused by a memcpy() macro being split by a directive (Keith Packard, David Dawes, #5150, Sami Farin). 692. Don't try to print mode names when NULL (David Dawes). 691. Revert the ATI driver's composite sync default to off (Marc La France). XFree86 4.2.0 (18 January 2002) 690. Workaround for hardware bug that prevents older ATI 3D Rage adapters from being assigned to XF86Config device sections (Marc La France). XFree86 184.108.40.206 (17 January 2002) 689. Fix bug introduced in snapshot 220.127.116.11 causing XDarwin's PseudoramiX extension to always be disabled (Torrey T. Lyons). 688.
