congestion")

sockaddr.

Jon/Ying, i have a very limited test setup, i hope you can review
and ensure that the proposed change is safe.
I have tested it (on net-next) that it at least solves the problem
i had.
Once the fix is mainline, i will submit patches to bash for
shell network redirection.
This should be in net, because it's a bug that breaks connectionless
messaging in many ways.
Feel free to forward it there after your review/signoff.
