One thing to examine is when WireGuard calls
`socket_clear_peer_endpoint_src'. This makes wireguard forget the
source address that it should be using and fall back to the default.
You could add a pr_info(...) call in this function. I have an inkling
that I make calls to this function too zealously and in potentially
unneeded places, such as on handshake transmission retries.
I'm headed out of town super soon, so likely debugging this will have
to wait until I'm back, but do let me know what you find, and we'll
get this fixed up upon return.
