Change subject: dco: fix crash when --multihome is used with --proto tcp ...................................................................... dco: fix crash when --multihome is used with --proto tcp Although it's a combination of options that is not really useful, when specifying --multihome along with --proto tcp and DCO is enabled, OpenVPN will crash while attempting to access c2.link_socket_actual (NULL for the TCP case) in order to retrieve the local address (in function dco_multi_get_localaddr()) Prevent crash by running this code only if proto is UDP. The same check is already performed in socket.c/h for the non-DCO case.
