ipfw3: lockless in-kernel NAT
The libalias is used in kernel space for in-kernel NAT, and its alias_link
entries are stored with LIST. so all the packets which need to be NAT will scan
against the LIST and trying to find the matched alias_link. by seperating the
libalias into context of different CPUs, the lock can be removed. and due to the
nature of NAT, the outgoing and incoming packets are possible to be handled by
different CPUs, to ensure the returning packet can be translated properly, the
newly created alias_link is required to be duplicated and inserted into contexts
of both CPUs.
e.g.
ipfw3 nat 1 config if em0
ipfw3 nat 1 all via em0
ipfw3 nat 1 show state

ipfw3: new feature 'ipfwsync'
ipfwsync is a new feature to synchronize firewall states between machines
which is running ipfw3 firewall for high availability. ipfw3 can be configured
in centre or edge mode. the centre will automatically sync the states from
centre to the edge.
e.g.
ipfw3 sync edge 5000
ipfw3 sync start edge
ipfw3 sync centre 192.168.1.1:5000,192.168.1.2:5000
ipfw3 sync start centre
ipfw3 sync show config
ipfw3 sync show status
ipfw3 sync test centre 123
