Issue

  • A wildcard policy is an IPsec policy that applies to multiple IP endpoints
  • When a wildcard IPsec policy is modified, ONTAP needs to delete the extant IKE SAs associated with the policy
  • The bug caused ONTAP to not delete all the old IKE SAs.
  • Since IKE SAs still existed for the client IPs, ONTAP expects traffic from those clients to be encrypted.
  • When the clients sent unencrypted traffic, ONTAP dropped the unencrypted traffic without responding.
