Hello, > I have written a usb device driver, which displays receives the data > exactly as am sending from the device, but as soon i call skb_pull(skb, 1) it > crashes the kernel. It doesn even call netif_rx(skb) to send the > > skb to next layer, can some one suggest what might be the problem. Can you please check the values of a : skb->len and b : skb->data_len because by the definition of the skb_pull () ..... there is BUG_ON(skb->len < skb->data_len); if you need to understand the relation between skb->len and skb->data_len then please refer " http://kerneltrap.org/node/16224 " because me too not clear on how skb fragments are handled in kernel Hope this helps :) -Smital Desai ______________________________________________________________________ The contents of this e-mail and any attachment(s) may contain confidential or privileged information for the intended recipient(s).
