econet: fix CVE-2010-3848
Don't declare variable sized array of iovecs on the stack since this could cause stack overflow if msg->msgiovlen is large. Instead, coalesce the user-supplied data into a new buffer and use a single iovec for it. Signed-off-by: Phil Blundell <philb@gnu.org> Signed-off-by: David S. Miller <davem@davemloft.net>
