Public bug reported: Neutron has already been able to make the agentless driver receive the security group BEFORE/AFTER event by neutron callback logic[1]. But this logic still lacks the precommit function, like in Ml2 mechanism driver, which guarantees that the mechanism driver DB and neutron DB operation are in the same transaction. Because the MD may want to have the event callback function and hope its own DB operation in the same transaction with neutron securitygroup db.
Another problem is that there is no guarantee that at least one MDs will handle a security group event. May other extension like QOS have the similar problem. more info could be find here https://review.openstack.org/#/c/240356/5/ ** Affects: neutron Importance: Undecided Status: New ** Tags: rfe -- You received this bug notification because you are a member of Yahoo!
