I am getting error
network.c:32: dereferencing pointer to incomplete type
If this is what I think it is, it's a C issue and not a kernel issue. I think this is the error you get when the compiler needs to know the definition of a struct but the struct isn't defined in the current translation unit.
Cannot figure out why. Since struct sk_buff **pskb points to sock struct and sock struct has a field ny the name of family.
Please help

#include <linux/errno.h> #include <linux/types.h>
#include <linux/socket.h>
Try including linux/sock.h if you want to use the sk member of the struct sk_buff. Otherwise struct sock isn't defined.

struct sk_buff **pskb,
...
printk("sk->family = %x\n", (*pskb)->sk->family);
