Fixed In Version: openstack-neutron-7.2.0-23.el7ost Doc Type: Bug Fix
Doc Text:
Previously, iptables_hybrid and iptables firewall drivers were not compatible with the new iptables package shipped with RHEL. The new iptables package introduced file locking when calling the iptables-restore command. Consequently, attempts to configure firewall rules using iptables_hybrid or iptables firewall drivers would sometimes fail. With this update, the iptables file is correctly locked when calling iptables-restore inside the iptables_hybrid or iptables firewall drivers. As a result, no errors occur when applying firewall rules to neutron ports.
