netlink: netlink_recvmsg() fix commit 1dacc76d0014 (net/compat/wext: send different messages to compat tasks) introduced a race condition on netlink, in case MSG_PEEK is used. An skb given by skb_recv_datagram() might be shared, we must copy it before any modification, or risk fatal corruption. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
