[strongSwan-dev] MIB for IKE

HI Martin,

I have a requirement where I need to update the status of IKE to the ESP
packet processing in a HA scenario. IKE and ESP processing runs on
different cores. The only means to syncronize IKE and ESP Processing is via
tables where tables updation is done by IKE and tables look ups by ESP
processing. The tables are shared between IKE and ESP.

I could see the ha_message.h in strongswan sending messages to nodes in HA
scenarios but in my case I need to update the tables so the ESP would
timely update this. I don't have any IPC mechnisms to use apart from tables.

So was the reason I posted in my previous message on the chances of an IKE
MIB so I could use the structures to update ESP Processing. But as Andreas
confirmed of no MIB.

Please help me on the list of IKE structures
for ike_keys(),ike_updown(),ike_**rekey(),message(),child_keys()**,child_state_change()
