This is neat. So just confirming that I understand (thanks for re-cc'ing
me btw <3):

Because of the UDP glitch, it can cause either the kernel panic in the UDP
code, but also elsewhere in the TCP stack based on if it's fiddling with
the same DST being hosed by a UDP packet?

Unfortunately we're observing a pretty severe sintr cpu increase under
3.14, so I'm going to try this on 3.10.latest. Any potential issues there?

Thankfully it seems like our udpkill utility will reproduce it quickly.
Lets see how it goes!

This is a start, because we have other bugs of the same kind.

I was working on follow up
