I would think the obvious way to mine data from IP packets would be to use a netfilter rule to queue them up for a user process to manipulate. --- Sandy, thx for your comment but... but i __do_not_need__ to store packets in user space - only some information from packet processing path (timing execution). After the analysis I want to be able to say: " in cycle number X packet number Y has its header processed, few cycles afterwards there was next hop LOOKUP that took Z cycles etc." So i dont need to queue packets in user-space (at least this is what i think). i only want to dump some informational data into buffer to prevent from performance hit that might happen when writing to some file. i would like to vmalloc some mem. and i would ask you to tell me how. regards, adam - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
