arif at khost:~/src/linux$ global -x ip_rcv_finish
ip_rcv_finish 319 net/ipv4/ip_input.c static int
ip_rcv_finish(struct sk_buff *skb)
Now if i want to use this function i need to initialize a pointer to
this function.
To be able to do that i need the address of the function.
I've seen that from user space i can read /proc/kallsyms to get an
address of a symbol. Is their any similar mechanism exist where i can
read the symbol table to extract a symbol's address from kernel space?

check http://lxr.linux.no/#linux+v3.6.8/include/linux/kallsyms.h
I have a good guess, what you need is kallsyms_on_each_symbol()

Thanks for the pointer. I'm testing what can be done.
