Description of problem:
Backport fix for bz1415800 to Openshift Container Platform 3.4
Version-Release number of selected component (if applicable):
Requesting backport of the change to 3.4 in the installer so the installer waits to obtain a lock when updating iptables rules ensuring that rules are properly created
I have not found any existing bugzilla to get this change backported into 3.4
Verified with version openshift-ansible-3.4.80-1.git.0.4eee9b7.el7.noarch. During installation, run a while loop of iptables command on hosts, installer will be slow down at "TASK [os_firewall : Add iptables allow rules]" step, once stop the while loop, installer continue with normal speed.
[root@master ~]# while true; do iptables -nL; done
[root@ansible ~]# ansible-playbook -i hosts -v /usr/share/ansible/openshift-ansible/playbooks/byo/config.yml
TASK [os_firewall : Add iptables allow rules] **********************************
(slow down here during the "while loop" alive)
