Date: Tue, 13 Sep 2011 12:21:37 +0300 From: Christoph Paasch <christoph.paasch@...ouvain.be> To: netdev@...r.kernel.org Subject: pskb_copy() in tcp_transmit_skb() Hi, I'm trying to understand the reason for the possible call to pskb_copy() in tcp_transmit_skb(). I don't find, where we may have a cloned skb entering tcp_transmit_skb(). The original pskb_copy() came from tcp_retransmit_skb() (commit dfb4b9dceb35c567a595ae5e9d035cfda044a103). But from that point, the git-history does not show where the pskb_copy() is coming from. Does somebody has an idea, how a cloned skb can be passed to tcp_transmit_skb() and thus trigger this call to pskb_copy().
