Re: reading the tcp headers within the write queue
From: Gavin McCullagh [EMAIL PROTECTED] Date: Thu, 13 Dec 2007 18:56:26 + I'm trying to hack together something which will run through the retransmit queue looking at the tcp headers. The packets in the retransmit queue are headerless, the header only gets added to clones of the retransmit queue frames during the actual transmit. And this question belongs on netdev not linux-net. -- To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Hi, thanks for the swift reply. On Thu, 13 Dec 2007, David Miller wrote: I'm trying to hack together something which will run through the retransmit queue looking at the tcp headers.

I presume there isn't any other residue of the tcp options elsewhere, that one could look at when the packet gets acknowledged? I'm particularly interested in the timestamp. And this question belongs on netdev not linux-net. Oops, sorry.

Every time we transmit, the timestamp will be different. We store the jiffies at transmit time in TCP_SKB_CB(skb)-when, so you can use that. This is the value we use to compute the timestamp. -- To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
