Q: ip_build_and_send_pkt

Hello. I have a couple of questions about 2.4.5 IP layer and will be very grateful if someone will answer :) In net/ipv4/ip_output.c there is the function ip_build_and_send_pkt(). This function adds an IP header to given skbuff and sends it out. But it seems that the only place where this funct

Q about ip_local_deliver_finish

Hello. I have a question (maybe stupid but I spent a lot of time trying to find an answer)about ip_local_deliver_finish() in 2.4.4. kernel. I'll be very grateful if someone explains me what's happening. There is the following piece of code in ip_local_deliver_finish() (in net/ipv4/ip_input.c):

Question about ipip implementation

Hello! I read net/ipv4/ipip.c. It seems to me that ipip_rcv() function after "unwrapping" tunelled IP packet creates "virtual Ethernet header" and submit corresponding sk_buff to netif_rx(). Is there a some reason to do things this way instead of calling ip_rcv() for "unwrapped" IP packet? --
