3.8.13.4 -stable review patch.  If anyone has any objections, please let me 
know.

------------------

From: Wei Yongjun <yongjun_...@trendmicro.com.cn>

commit c802d759623acbd6e1ee9fbdabae89159a513913 upstream.

sizeof() when applied to a pointer typed expression gives the size of the
pointer, not that of the pointed data.
Introduced by commit 3ce5ef(netrom: fix info leak via msg_name in nr_recvmsg)
