ha and updown...
Currently updown script isn't called on passive node, which makes left|rightfirewall option incompatible with the ha usage scenarios.
As the fix is quite simple (patch attached) and seems to be working just fine, I am wondering if this was left out on purpose or just an oversight...

It looks I was a bit over optimistic. With the above/first patch the
updown script is not called when passive IKE SA is destroyed (during reauthentication and/or maybe otherwise), so in the modified patch the
child_updown() is called (for each CHILD SA) in the
ike_state_change() function when a passive IKE SA is being destroyed. I am not sure if this is the right place for the
child_updown() call or if there is a more appropriate mechanism for this.
I have also noticed that, as the CHILD_SA rekeying on the passive node is made of creating new CHILD SA and dropping old one, there is an extra
updown/child_down call for each CHILD SA rekeying.
By the way, I also had to modify
updown script for
iptables to insert rules after the general
-j CLUSTERIP rule -
iptables -I INPUT 3 ...
