Hello, I am kind of new to kernel networking and I am trying to implement logical clocks at the kernel level. After trying to do it using ancillary messages (but failed) I decided to modify the struct sk_buff by adding it a new field called lclock. I added the init of the lclock field to dev_queue_xmit and I also take care of the field in skb_header_init, skb_clone and copy_skb_header. When I send a message from one machine to another though, it looks like the received sk_buff does not contain the updated lclock field. Can anyone please tell me if there is any place where the sk_buff is packed to be sent over the network and if I need to pack the lclock field sepparately. Also, the same question for unpacking the received sk_buff. Is there a function that takes care of that? I looked through the kernel in the last days and I could not figure it out. Could it be that each driver packs the sk_buff differently and independently of the others? Any help is deeply appreciated.
