To handle Phase 2 exchanges on the other HA host we need to sync the last
block of the last Phase 1 message (or the last expected IV). If the
gateway is the initiator of a Main Mode SA the last message is an
inbound message. When handling such messages the expected IV is not
updated until it is successfully decrypted so we can't sync the IV
when processing the still encrypted (!plain) message. However, as responder,
i.e. if the last message is an outbound message, the reverse applies, that
is, we get the next IV after successfully encrypting the message, not
while handling the plain message.
Fixes#1267.
It is required for IKEv1 to determine the DH group of the CHILD SAs
during rekeying. It also fixes the status output for HA SAs, which so
far haven't shown the DH group on the passive side.
Fixes#1267.
When the IKE_SA is synced without the remote address, after a
reauthentication charon is not able to find it in its connected_peers
table since the destination host will be %any (it's missing in the
message, hence the default from the newly created ike_sa_t -- %any --
will be used).
By adding the value to the HA_IKE_ADD message, we should be able to
solve this problem.
