    In this afternoon, i find this statement in alloc_skb function:
" memset(skb, 0, offsetof(struct sk_buff, truesize));"

After " security_skb_alloc "  function, the skb->lsm_security is set to
0.

Maybe i am wrong. But if it happen, it's NOT necessary to allocate
sk_buff security struct .

Can someone tell me what's the reason?
