            Bug ID: 254212
           Summary: can't initialize an if_wg interface with IPv6 disabled
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: markj at FreeBSD.org

if_wg creates IPv4 and IPv6 listening sockets.  sobind() will fail for the IPv6
socket when the vnet has no IPv6 addresses assigned to any interface, see the
first check in in6_pcbbind().  So if one creates a fresh vnet and instantiates
a wg interface there, the link won't come up.  As a workaround one can do
something like "ifconfig lo0 up", since that automatically assigns ::1.  I'm
not sure why that check in in6_pcbbind() is needed in the first place.
