Subject: [PATCH] Ensure check of nlmsg length is performed before actual
 access

During a brief code review we noticed that the length field expected 
inside the payload of the message is accessed before it is ensured that 
the payload is large enough to actually hold this field.

The people mentioned in the commit message helped in the overall code 
review.

Kind regards,
Max
