Bug 1400597

Description of problem:

Port 53 udp & tcp are opened in firewalld, able to connect to master through port 53.

But getting following failure message when firewalld is turned on

info: zone xxxxxxx/xxxx: refresh: failure trying master x.x.x.x#53 (source 0.0.0.0#0): operation cancelled

Version-Release number of selected component (if applicable):

bind-chroot-9.9.4-38.el7_3.x86_64

How reproducible:

Always when firewalld is turned on

Steps to Reproduce:

1: Setup Master Slave DNS (Chroot)

2: Configure logging on Slave

logging {
        channel chrooted_logfile {
                file "/var/log/named";
                severity info;
                print-time yes;
                print-category yes;
                print-severity yes;
        };
        channel debug_chrooted_logfile {
                file "/var/log/debug_named";
                severity debug;
                print-time yes;
                print-category yes;
                print-severity yes;
        };
        category default { chrooted_logfile; };
        category notify { chrooted_logfile; };
        category config { chrooted_logfile; };
        category update { chrooted_logfile; };
        category lame-servers { null; };
        category resolver { null; };
        category database { null; };
        category security { chrooted_logfile; };
        category xfer-in { chrooted_logfile; };
        category xfer-out { chrooted_logfile; };
};


3: Turn on firewalld on Slave

4: Check debug log

Actual results:

failure trying master operation cancelled

Expected results:

The error should not appear.
