record_login() copies addr by calling login_set_addr() but just
sizeof(struct sockaddr).  Since sizeof(struct sockaddr) is equal to
sizeof(struct sockaddr_in), IPv4 is not affected.  However,
sizeof(struct sockaddr) is too short against sizeof(struct
sockaddr_in6).  This breaks IPv6 address.

Sincrely,
