I`m having trouble running some games (JadeDynasty,War Of The Immortals) after I have installed them and I need to determine if this is the problem. Is anyone famaliar with the following msg: SELinux is preventing wine-preloader from mmap_zero access on the memprotect . ***** Plugin mmap_zero (53.1 confidence) suggests ************************** If you do not think wine-preloader should need to mmap low memory in the kernel. Then you may be under attack by a hacker, this is a very dangerous access. Do contact your security administrator and report this issue...

...orking last night - no hardware alarm lights, but keyboard/monitor/network unresponsive. After a reboot I see a large stack of messages like this in /var/log/messages: ---- Aug 20 14:02:34 opennms-h-03 python: SELinux is preventing /usr/sbin/monitor-get-edid-using-vbe from mmap _zero access on the memprotect . ***** Plugin mmap_zero (53.1 confidence) suggests ************************* If you do not think /usr/sbin/monitor-get-edid-using-vbe should need to mmap low memory in the kernel.

...utput. This other log line may be relevant (or not): Apr 13 08:35:30 localhost kernel: type=1400 audit(1271144119.830:4): avc: denied { mmap_zero } for pid=462 comm="vbetool" scontext=system_u:system_r:vbetool_t:s0-s0:c0.c1023 tcontext=system_u:system_r:vbetool_t:s0-s0:c0.c1023 tclass=memprotect On the other hand, both CRTC's are using output B. I'm not that familiar with the hardware, and this may be completely wrong, but I assume an output can only be used by a single CRTC. Cheers, Renato

...I'm not just looking to implement garbage collection that may have been done already in a better way, I will be conducting research into stack handling routines for multi-threaded programs. As such, I will need to have complete control over the stack, including the ability to * Add memprotected regions before and after stack pages, with the intention to catch the interrupt/signal and modify the stack * Hook before functions place data on stack, possibly moving the stack pointer before data is placed * Hook before functions return with explicit control over where the new stack...

Hello, I have been thinking about efficient implementation of dynamically typed languages in my spare time. Specifically, I'm working on a toy implementation of a tiny piece of Python using LLVM as a native code generating JIT. I've run into a bit of an issue, involving how Python deals with method calls. I'm not sure how/if I can implement this in LLVM. In Python, the following
