UDP TX\nreads the field without that lock. In particular, a concurrent IPv6\nupdate can therefore result in a torn address read.\n\nUse ovpn_peer_reset_sockaddr to publish a replacement bind when learning\na new local endpoint, just as a remote endpoint change does. Preserve\nthe current remote address and reset the dst cache only after the new\nbind has been published successfully.\n\nTrack remote endpoint changes separately so that float notification and\ntransport-address rehashing remain limited to actual peer floats."
