Well, it *changed* it. Does the rcu_defererence_check() only fire on the first time it hits something, so we've fixed the first one and now we get to see the second one?

It appears that way, otherwise you should have seen a second warning in nf_conntrack_ecache the last time. > (For what it's worth, if this is going to be one-at-a-time whack-a-mole, I'm > OK on that, just want to know up front.) I went through the other files and I believe this should be it. We already removed most of these incorrect rcu_dereference() calls a while back. > [ 9.299425] ip_tables: (C) 2000-2006 Netfilter Core Team > [ 9.299486] > [ 9.299486] =================================================== > [ 9.300499] [ INFO: suspicious rcu_dereference_check() usage. ] > [ 9.301001] --------------------------------------------------- > [ 9.301523] net/netfilter/nf_log.c:55 invoked rcu_dereference_check() without protection! > [ 9.302066] |
