From e7ac05f3407a3fb5a1b2ff5d5554899eaa0a10a3 Mon Sep 17 00:00:00 2001 From: Yasuyuki Kozakai Date: Wed, 14 Mar 2007 16:44:01 -0700 Subject: [NETFILTER]: nf_conntrack: add nf_copy() to safely copy members in skb This unifies the codes to copy netfilter related datas. Before copying, nf_copy() puts original members in destination skb. Signed-off-by: Yasuyuki Kozakai Signed-off-by: Patrick McHardy Signed-off-by: David S.
