IP-address from sk_buff

Question

I am writing a kernel module which registers a netfilter hook. I am trying to get the ip address of the caller by using the sk_buff->saddr member. Is there a way

Answer 1

/* Convinience union to __be32 to ip address  */
union ip_address {
    u8 a[4];
    __be32 saddr;
};

IP Address could be obtained a[0].a[1].a[2].a[3]
