hi!
Should this fix work against the nullpointer linux kernel vulnerability?
Should it break any services on a usual LAMP machine?
thx,

________________________________________
On the servers where I really care about security, I disable most
networking protocols by installing the attached file as:
/etc/modprobe.d/disabled-protocols
[Note that this file disables IPv6.]
It's safest to reboot after installing this file, in case any of
the networking-protocol modules have already been inserted into
the kernel.
