Exploit fix for kernel 2.6.22.9 and earlier

If you are like me and use CSF then 2.6.22.9 is the latest kernel version to work with it. So I usually use this version plus grsecurity. This is the same fix as in my tarball I posted earlier.

cd into your kernel source directory

 nano -w fs/splice.c

look for this set of lines

(ctrl+w)

if (unlikely(!len))

you should see

                 if (unlikely(!len))
break;
error = -EFAULT;
if (unlikely(!base))

replace

               if (unlikely(!base))

with

                if (!access_ok(VERIFY_READ, base, len))

save the file and then compile your kernel as you normally do
