net: sock: validate data_len before allocating skb in sock_alloc_send_pskb()
[ Upstream commit cc9b17ad29ecaa20bfe426a8d4dbfb94b13ff1cc ]
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.
