I need to be able to encrypt skb->data as contiguous blocks of memory. So, skb_linearize(skb...); but, I need to be able to change any value within skb->data. According to various comments in kernel source, only data that is 'private' can be written to (i.e. use memcpy or skb_copy). That is, get_random_bytes(skb->data, skb->len) by itself will not change all parts of skb->data. So, is this what I'm expected to do?: skb_linearize(skb...); new_skb = skb_copy(skb...); <encrypt> skb_push(skb->len...); skb->data = new_skb->data; <minus obvious errors> This is really tacky and I want to be able to avoid the expensive skb_copy() func. -Mazhar Memon - : 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
