but this maps schemes directly (and to use the other function we'd

It is mandated by the RFCs and it is expected by the task managers.

Initial messages with invalid MID will be treated like regular messages,
so no IKE_SA will be created for them.  Instead, if the responder SPI is 0
no SA will be found and the message is rejected with ALERT_INVALID_IKE_SPI.
If an SPI is set and we do find an SA, then we either ignore the message
because the MID is unexpected, or because we don't allow initial messages
on established connections.

There is one exception, though, if an attacker can slip in an IKE_SA_INIT
with both SPIs set before the client's IKE_AUTH is handled by the server,
it does get processed (see next commit).

ikev2: Schedule a timeout for the delete message following passive IKE rekeying

Under some conditions it can happen that the CREATE_CHILD_SA exchange for
rekeying the IKE_SA initiated by the peer is successful, but the delete message
does not follow. For example if processing takes just too long locally, the
peer might consider us dead, but we won't notice that.

As this leaves the old IKE_SA in IKE_REKEYING state, we currently avoid actively
initiating any tasks, such as rekeying or scheduled DPD. This leaves the IKE_SA
in a dead and unusable state. To avoid that situation, we schedule a timeout
to wait for the DELETE message to follow the CREATE_CHILD_SA, before we
actively start to delete the IKE_SA.

Alternatively we could start a liveness check on the SA after a timeout to see
if the peer still has that state and we can expect the delete to follow. But
it is unclear if all peers can handle such messages in this very special state,
so we currently don't go for that approach.

While we could calculate the timeout based on the local retransmission timeout,
the peer might use a different scheme, so a fixed timeout works as well.
