Date: Mon, 17 Oct 2005 20:09:03 -0400 From: Mark Schreiber <mark7@alumni.cmu.edu> To: ryan@clutteredmind.org Subject: [PATCH]SDL mprotect() crash fix (I'm going to throw this patch your way at the suggestion of #SDL -- for some reason, I had some difficulty sending it to the main list last time, and I go bonkers subscribing to send each email or patch...) Currently, when I run SDL applications as non-root using SDL_VIDEODRIVER=dga, the fbdev fallback mprotect()s read/write the proper size of mmapped /dev/fb0 (7.5MB), but on framebuffer release mprotect()s read-only the range by the entire size of my video memory (128MB), which causes a segfault: #0 0x002a9a27 in ??

I've attached a one-line patch against SDL CVS that updates the size of the framebuffer at framebuffer map time so that the mprotect() on unmap will be the same size. I'm not sure if this is the best approach (i.e. one might want to retain the original value), but it does make my SDL applications work without segfaulting. -- Best of luck, Mark Schreiber

Ryan C. Gordon <icculus@icculus.org> [Thu, 17 Nov 2005 03:04:47 +0000] rev 1172
Don't crash if a NULL is passed for a "%s" parameter to SDL_SetError(), instead replace it with the string "(null)", like glibc's printf() would do.

Ryan C. Gordon <icculus@icculus.org> [Sat, 05 Nov 2005 19:53:37 +0000] rev 1168
Dynamically load X11 libraries like we currently do for alsa, esd, etc. This allows you to run an SDL program on a system without Xlib, since it'll just report the x11 target unavailable at runtime.
