We need to apply this bug fix:

    ipv6: Allow inet6_dump_addr() to handle more than 64 addresses
    
    Apparently, inet6_dump_addr() is not able to handle more than
    64 ipv6 addresses per device. We must break from inner loops
    in case skb is full, or else cursor is put at the end of list.

Tagging this as 'security' because the system may accept connection
attempts to an address which doesn't appear to be assigned to it.
