    Problem solved

    Indeed, the pointer to pointer was the problem.
    However, who is implementing with netfilter.h needs to be careful about that. From kernel 2.6.20 (I guess) it is a pointer only to skb sk_buff structure. But, from 2.6.19 version and lesser ones it is a double pointer (**skb).

        Try someting like this:

        if (strcasecmp(lin e, "Importance : High") == 0) {
        }

          Actually, it seems to be an "light problem"...
          All you need to do is write an "while" or a "for" loop.
          The loop should go from 0 (zero) to the ALPH_PHONE_SIZE-1.
          Probably you will read the phone from the user and store the information in a array char (or string).
          Then, inside the loop you should access each position of this array/string and compute the information.
          If you use a "while"...

            invalid pointer initialization

            Hello all,

            I'm facing some problems to compile a new module for Linux Ubuntu 8.04, kernel version 2.6. Above are two pieces of code related to the problem.

            linux/netfilter.h
            Code:
            //begin netfilter
...
typedef unsigned int nf_hookfn(unsigned int hooknum, struct sk_buff *skb, const struct net_devide *in, const struct net_device *out, int (*okfn)(struct sk_buff *));
...
struct nf_hook_ops
            ...
