[strongSwan-dev] [PATCH] starter: cleanup SAs when deleting a connection

Thanks for your patch: I think it is definitely a good idea to flush connections that are no longer up to date with the configuration files.
Did you manage to make an updated patch?
I have another related problem:
I have two CA certificates in ipsec.d/cacerts. I can see them using "ipsec listcacerts"
If I remove one of them and perform a "ipsec rereadcacerts", I can see in charon's log that the only remaining CA certificate is reloaded.
However, I still see the two CA certs using the "ipsec listcacerts" command. "ipsec purgecerts" does not seem to help.
Remote peers successfully manage to authenticate using the removed CA cert, that is quite annoying.

You're right, this makes sense. I'll provide an update that makes it optional.
