hello all , actually i am writing the custom table at forward hook in netfilter framework. so , as we know that if we want to pass argument at insertion time we can pass it by using module_param(), so i did it successfully. but problem occurs , when i want to pass array of structure to my module , i will explain it in brief struct Queue{ int src_ip; int dst_ip; int tcp_port_src; int tcp_port_dst; int protocol; char *action; /*NF_ACCEPT,NF_DROP,NF_QUEUE*/ }node[5]; so , now i want that i should be able to set the 5 diff. rules at the time of insertion. but i tried it alot , but no result. so , plz anybody will suggest me how to do it, or any other idea to set various rule by command line. thanks .....
