I am wondering if someone recently changed the behaviour of Ubuntu 12.04 (in 
12.04.3)
so that kernel.kptr_restrict is always 1 and cannot be changed.


Notice:

# ls -l /prov/sys/kernel/kptr_restrict
-rw-r--r-- 1 root root 0 Oct 15 15:18 /proc/sys/kernel/kptr_restrict

# cat /proc/sys/kernel/kptr_restrict
1


If the value is already "1", then the line trying to set it to "1" can safely 
be commented out in this file:

/etc/sysctl.d/10-kernel-hardening.conf


Does anyone have any additional insights?
