Jim,
I've checked a set of changes where we pass the correct address length
to all calls to sendto now. Rather than change function signatures all
over the place to add address lengths, I just use the family member to
determine what the correct length should be and pass this value. A
better solution would be to rework the code so that sizeof
sockaddr_storage is used whenever a buffer is expected to receive an
address, and to pass around the length of previously stored addresses
with the address itself.
This change was a bit less intrusive - you don't need a lot of churn
right now, I'm presuming. :)
