ERK!
We changed the socklnd wire protocol so that we could do zero-copy sends
without requiring a kernel patch. This change should still
allow connection establishment with "old" peers, so I'm surprised that
you've seen "all manner of assertion failures". Could you
let me see some? Are they in the socklnd?
Here's a representative one. I got this kind of thing every time an older
client tried to connect, and the problem went away as soon as I shut down or
updated the older clients. I didn't do much further debugging than that.
