| |
I fixed a bug in pktgen so it won't cause oops when used with balance-tlb or balance-alb bonding driver:
--- linux-2.6.17.4/net/core/pktgen.c.orig 2006-07-06 16:02:28.000000000 -0 400 +++ linux-2.6.17.4/net/core/pktgen.c 2006-07-10 16:40:47.000000000 -0400 @@ -2149,6 +2149,9 @@ skb->mac.raw = ((u8 *) iph) - 14 - pkt_dev->nr_labels*sizeof(u32); skb->dev = odev; skb->pkt_type = PACKET_HOST; + skb->mac.raw = eth; + skb->nh.iph = iph; + skb->h.uh = udph;
if (pkt_dev->nfrags <= 0) pgh = (struct pktgen_hdr *)skb_put(skb, datalen); The root cause is that the bond_alb_xmit in bonding will peek the destination address in packet via the skb->nh.iph pointer, generally this will be filled by upper layer network driver, but the packet generated by pktgen will be sent to device driver so it will need to set this pointer correctly. The other two pointers are not necessary for now, they are set to avoid similar problem.
