netfilter: nf_conntrack: properly account terminating packets
Currently the last packet of a connection isn't accounted when its causing abnormal termination. Introduces nf_ct_kill_acct() which increments the accounting counters on conntrack kill. The new function was necessary, because there are calls to nf_ct_kill() which don't need accounting: nf_conntrack_proto_tcp.c line ~847: Kills ct and returns NF_REPEAT. We don't want to count twice. nf_conntrack_proto_tcp.c line ~880: Kills ct and returns NF_DROP. I think we don't want to count dropped packets. nf_conntrack_netlink.c line ~824: As far as I can see ctnetlink_del_conntrack() is used to destroy a conntrack on behalf of the user. There is an sk_buff, but I don't think this is an actual packet. Incrementing counters here is therefore not desired.
