sk_data_ready callback not able to get fragment data

davidpreetham · 05-08-2018, 08:34 AM

sk_data_ready callback is given with function. processing skb by acquiring read_lock(&sk->sk_callback_lock). skb->data_len shows fragment size. but when we deference skb shared info structure shinfo = skb_shinfo(skb), shinfo->nr_frags show zero, nr_frags value is zero. Is there anyway we can get data from fragments.

How can we tell you, since you've given us absolutely ZERO details. You don't say what you're doing, in what language, with what hardware, on what version/distro of Linux, etc. No way of guessing.
