====================
fix skb length accounting after XDP frag adjustment

This series fixes skb length accounting after an XDP program adjusts its
fragment area, in both the generic XDP path (net/core/dev.c) and the veth
native path (drivers/net/veth.c). When the fragment area is resized,
skb->len and skb->data_len can go out of sync, and in the reproduced UDP
receive path this leaked skb_shared_info contents (including a kernel
pointer) to userspace while truncating real payload.
