net: sock: validate data_len before allocating skb in sock_alloc_send_pskb() We need to validate the number of pages consumed by data_len, otherwise frags array could be overflowed by userspace. So this patch validate data_len and return -EMSGSIZE when data_len may occupies more frags than MAX_SKB_FRAGS. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: David S.
