Patch for 2.6.20?

[dweekly]

grsecurity-2.1.10-2.6.20.4-200703261947.patch is working just grand for me so far.

[nopjunkie]

with grsecurity-2.1.10-2.6.20.4-200703271911.patch, it dies compiling here:

arch/i386/lib/mmx.c: In function ‘_mmx_memcpy’:
arch/i386/lib/mmx.c:75: error: ‘cr0’ undeclared (first use in this function)

make[1]: *** [arch/i386/lib/mmx.o] Error 1

unless you have CONFIG_PAX_KERNEXEC enabled

lines 34-36 of arch/i386/lib/mmx.c:

Code: Select all

#ifdef CONFIG_PAX_KERNEXEC
   unsigned long cr0;
#endif


but then line 75 does:

Code: Select all

      ...
      : "=&r" (cr0) : "r" (from) : "ax");


the easy fix is obviously just to enable CONFIG_PAX_KERNEXEC, which is probably what everyone wants anyways.

Anyone tried 2.6.20.6 yet?

I am running 2.6.20.6 at the moment without any problems. Waiting for 2.6.20.7
