Date: Tue, 18 Oct 2011 20:49:46 +0530 From: raviraj joshi <raviraj.j1991@...il.com> To: linux-kernel@...r.kernel.org Subject: kenel level packet capturing 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. How ever 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. regards, Raviraj Joshi PICT,Pune. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
