-stable review patch. If anyone has any objections, please let us know. ------------------ From: Thomas Chenault [ Upstream commit 995b337952cdf7e05d288eede580257b632a8343 ] When called with a consumed value that is less than skb_headlen(skb) bytes into a page frag, skb_seq_read() incorrectly returns an offset/length relative to skb->data. Ensure that data which should come from a page frag does. Signed-off-by: Thomas Chenault Tested-by: Shyam Iyer Signed-off-by: David S.
