Eric Paris 5d53626100 nlmsg_ok comparison between signed and unsigned 
The nlmsg_ok macro has a comparison between an int and a size_t
(unsigned int).  The C spec says the int is cast to unsigned int before
the comparison.  This is a problem as the audit system will send skb's
with skb->len == nlhhdr->nlmsg_len which are NOT aligned.  Thus you can
end up with remaining being negative.  So the comparison becomes

(unsigned int)(-1) >= (unsigned int)16

Which turns out to be true!  It should clearly be false.  So if we cast
the size_t to an int we get a signed comparison and it works.  (This is
what linux/netlink.h and all of the kernel netlink headers do)
