From af14cca162ddcdea017b648c21b9b091e4bf1fa4 Mon Sep 17 00:00:00 2001 From: Jozsef Kadlecsik Date: Tue, 21 Feb 2012 14:53:57 +0100 Subject: [PATCH] netfilter: ctnetlink: fix soft lockup when netlink adds new entries Marcell Zambo and Janos Farago noticed and reported that when new conntrack entries are added via netlink and the conntrack table gets full, soft lockup happens. This is because the nf_conntrack_lock is held while nf_conntrack_alloc is called, which is in turn wants to lock nf_conntrack_lock while evicting entries from the full table. The patch fixes the soft lockup with limiting the holding of the nf_conntrack_lock to the minimum, where it's absolutely required.
