Hi, We are making a kernel level packet capture module as a part of our BE project . We are finding it difficult to understand kenel networking code. We studied structures and functions like sk_buff, netif_rx(),dev_alloc_skb. However we were not able to trace the actual path a simple packet follows. Moreover we tried to count the no of times netif_rx function was called it was much much lower than amount of packets actually being received. Can anyone please let us know the reason for this and how to approach the problem of writing a kernel level packet capture module ,resoruces we need to refer to (we are currently constrained to documents on kernel-networking available online). And even from where to get information about how forwarding(or packet flow) occours when we have virtual bridges (in terms of networking code). regards, Raviraj Joshi PICT,Pune. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
