Hi all, I've identified you as people who have at some point in the past emailed one of the Linux lists with problems with e1000 and sk_forward_alloc. It seems to be fairly widespread, but only seems to have appeared with recent kernel changes (after 2.6.12...) What I need from you is a reproducible test, and some information. I have never been able to reproduce this, and I'm trying to isolate the problem a bit. What motherboards are you using? What seems to cause this problem? Are you all using iptables? Are you all routing? From the reports I assume none of you are using an 82571/2/3 (pci express) As far as I know e1000 has the same requirement as tg3 and some others where we have to modify the header of the skb in the case of transmits using TSO. I don't see anywhere else that the driver modifies the skb. Tomorrow I'll generate a patch to try a more paranoid copying of the skb, I hope some of you can test. To do this we have code like so in e1000_tso: 2529 if (skb_shinfo(skb)->tso_size) { 2530 if (skb_header_cloned(skb)) { 2531 err = pskb_expand_head(skb, 0, 0, GFP_ATOMIC); 2532 if (err) 2533 return err; 2534 } 2535 2536 hdr_len = ((skb->h.raw - skb->data) + (skb->h.th->doff << 2)); 2537 mss = skb_shinfo(skb)->tso_size; 2538 if (skb->protocol == ntohs(ETH_P_IP)) { 2539 skb->nh.iph->tot_len = 0; 2540 skb->nh.iph->check = 0; Thanks for your assistance Jesse ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
