[NETFILTER]: ctnetlink: make sure event order is correct
The following sequence is displayed during events dumping of an ICMP connection: [NEW] [DESTROY] [UPDATE] This happens because the event IPCT_DESTROY is delivered in death_by_timeout(), that is called from the icmp protocol helper (ct->timeout.function) once we see the reply. To fix this, we move this event to destroy_conntrack(). Signed-off-by: Pablo Neira Ayuso <pablo@eurodev.net> Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
