-------------------------------------
Assignee: Murali Reddy
> Egress rules functionalty broken when protocol=all specificed from 4.6
> ----------------------------------------------------------------------
>
> Key: CLOUDSTACK-9495
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9495
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Affects Versions: 4.6.2, 4.7.1, 4.8.0, 4.9.0
> Reporter: Murali Reddy
> Assignee: Murali Reddy
> Fix For: 4.10.0.0, 4.9.1.0
>
>
> Egress rules handling in
> systemvm/patches/debian/config/opt/cloud/bin/configure.py, class CsAcl,
> add_rule() has below logic for handling protocol
> {code}
> if rule['protocol'] != "all":
> fwr += " -s %s " % cidr + \
> " -p %s " % rule['protocol'] + \
> " -m %s " % rule['protocol'] + \
> " --dport %s" % rnge
> {code}
> There is no else block to handle case when protocol in 'all' in which case
> CIDR never gets passed to the iptables command, hence resulting in accept all
> rule FW_EGRESS_RULES chain.
> To reproduce the issue just give any cidr in the guest subnet, for e.g.
> 10.1.1.27/31 and protocol all and see the result in FW_EGRESS_RULES of the
> filter table, you will see accept all rule.
