This line is added in the beginning of the file ip_output.c int (*test_function)(struct sk_buff *)=0; The following lines are added in function ip_finish_output2 // original definitions if((*test_function)(skb)) { kfree_skb(skb); return 0;} else { // original code The kernel compiles, but it is having problems as on restarting, there is some stack problem in rpc.statd and the comp hangs. Could anyone guide me as what maybe causing trouble. As the module is not loaded on startup, I guess that won't be a problem.
