Hi, There are 2 kinds of approach discussed in this forum for the receiving of tcp packets without going through the tcp state machine.
1) introduction of tcp_encap hook , which means a change in the existing kernel, 2)Using tcp raw sockets and sk->sk_data_ready callback function for receiving the tcp packet. This would not involve a change in the kernel. Could you please let me know why was the first approach chosen, despite both the approaches does the same thing. Thanks & Regards, Satish
