Subject: [PATCH] This code has been broken for ~ 20 years! Initialise the
 'fromlen' parameter for recvfrom() prior to the call, instead of passing in a
 'random' value off the stack. This should fix the problems with ypbind on
 current. I suspect the old kernel was not objecting to -ve buffer lengths.
