[Bug 1523835] [NEW] Call fun _ip_prefix_arg twice but only one play a role

 

Public bug reported:

In file neutron/agent/linux/iptables_firewall.py, when exec fun
_generate_plain_rule_args(self, sg_rule) for sg_rule using remote_ip,
the fun _ip_prefix_arg was called twice for 'source_ip_prefix' and
'source_ip_prefix'.

But for a sg_rule with direction, the ingress sg_rule only need:
                                                _ip_prefix_arg('s', sg_rule.get('source_ip_prefix'))
The egress_rule only need:
                                               _ip_prefix_arg('d', sg_rule.get('dest_ip_prefix'))
