Hello Ed L. Cashin,
The patch 6fde53abc51d: "aoe: print warning regarding a common reason
for dropped transmits" from Oct 23, 2012, leads to the following
warning:
drivers/block/aoe/aoenet.c:62 tx()
error: 'skb' was already used up by dev_queue_xmit()
61) if (dev_queue_xmit(skb) == NET_XMIT_DROP && net_ratelimit())
62) pr_warn("aoe: packet could not be sent on %s. %s\n",
63) skb->dev ? skb->dev->name : "netif",
64) "consider increasing tx_queue_len");
It's a use after free bug.
regards,
dan carpenter
