how to send data using generic netlink?

[hong zhang]

List,

I want to send data from user space to kernel, generic netlink message does not have place to hold data see below,

struct nl_msg
{
	int			nm_protocol;
	int			nm_flags;
	struct sockaddr_nl	nm_src;
	struct sockaddr_nl	nm_dst;
	struct ucred		nm_creds;
	struct nlmsghdr *	nm_nlh;
	size_t			nm_size;
	int			nm_refcnt;
};

Should I use nl_data to do it or any other way?

Thanks.
