Hi all,
Loosely related to the discussion about /dev/mem and system security compromisation of about a week ago on kernel-newbies, there was this discussion today on lkml for the curious:

http://lkml.org/lkml/2010/11/4/94

which discusses a 'make /proc/kallsyms mode 400 to reduce ease of attacking' patch.

Thanks
Julie
