4.14-stable review patch. If anyone has any objections, please let me know. ------------------ This reverts commit 28c74ff85efd192aeca9005499ca50c24d795f61. >From Florian Westphal <fw@xxxxxxxxx>: It causes kernel crash for locally generated ipv6 fragments when netfilter ipv6 defragmentation is used. The faulty commit is not essential for -stable, it only delays netns teardown for longer than needed when that netns still has ipv6 frags queued. Much better than crash :-/ Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- net/ipv6/netfilter/nf_conntrack_reasm.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/net/ipv6/netfilter/nf_conntrack_reasm.c b/net/ipv6/netfilter/nf_conntrack_reasm.c index 2ed8536e10b6..611d406c4656 100644 --- a/net/ipv6/netfilter/nf_conntrack_reasm.c +++ b/net/ipv6/netfilter/nf_conntrack_reasm.c @@ -598,8 +598,6 @@ int nf_ct_frag6_gather(struct net *net, struct sk_buff *skb, u32 user) fq->q.meat == fq->q.len && nf_ct_frag6_reasm(fq, skb, dev)) ret = 0; - else - skb_dst_drop(skb); out_unlock: spin_unlock_bh(&fq->q.lock); -- 2.17.1
