bind restart needed to reflect changes to dynamic zone in multiple views

[Brian J. Murrell]

I am using BIND 9.7.2-P2.

I have two views, one "internal" and one for "external" queries.  In
both of those views I have some zones which are common so I put them
into their own file "zones.common" and include that file in both of the
views.

The problem I am having is that when I make a dynamic update to a common
zone, only the internal view sees that change.  External queries still
return the data prior to the update.  If I restart the server, then
external queries get the updated data.

To provide an (excerpted, for brevity) example...

---- zones.common ----
zone "rbl.interlinx.bc.ca" {
        type master;
        file "/etc/bind/master/rbl.interlinx.bc.ca.zone";
        allow-update { ... };
        allow-transfer { ... };
        allow-query { any; };
};
---- zones.common ----

---- named.conf ----
view "trusted" {
        match-clients { trusted_networks; }; // our internal networks
...
        include "/etc/bind/zones.common";
...
        zone "interlinx.bc.ca" {
                type master;
                file "/etc/bind/master/interlinx.bc.ca.zone";
                allow-update { ... };
                allow-query { ... };
                allow-transfer { ... };
        };
...
};

view "greatunwashed" {
        match-clients { any; }; // all others hosts
...
        include "/etc/bind/zones.common";
        allow-query { great_unwashed_allowed_query; };
        zone "interlinx.bc.ca" {
                type slave;
                file "/etc/bind/slave/interlinx.bc.ca.zone";
                masters { ... };
                allow-query { any; };
        };
};
---- named.conf ----

To demonstrate, given the above configuration:

greatunwashed_host $ host 1.2.3.4.rbl.interlinx.bc.ca.
Host 1.2.3.4.rbl.interlinx.bc.ca not found: 3(NXDOMAIN)

trusted_host $ host 1.2.3.4.rbl.interlinx.bc.ca.
Host 1.2.3.4.rbl.interlinx.bc.ca. not found: 3(NXDOMAIN)

dns_server $ nsupdate
> server localhost
> zone rbl.interlinx.bc.ca.
> update add 1.2.3.4.rbl.interlinx.bc.ca 60 A 127.0.0.2
> send
>

trusted_host $ host 1.2.3.4.rbl.interlinx.bc.ca.
1.2.3.4.rbl.interlinx.bc.ca has address 127.0.0.2

greatunwashed_host $ host 1.2.3.4.rbl.interlinx.bc.ca.
Host 1.2.3.4.rbl.interlinx.bc.ca not found: 3(NXDOMAIN)

dns_server # /usr/sbin/rndc reload
server reload successful

trusted_host $ host 1.2.3.4.rbl.interlinx.bc.ca.
1.2.3.4.rbl.interlinx.bc.ca has address 127.0.0.2

greatunwashed_host $ host 1.2.3.4.rbl.interlinx.bc.ca.
Host 1.2.3.4.rbl.interlinx.bc.ca not found: 3(NXDOMAIN)

dns_server # service bind9 restart
 * Stopping domain name service... bind9
   ...done.
 * Starting domain name service... bind9
   ...done.

trusted_host $ host 1.2.3.4.rbl.interlinx.bc.ca.
1.2.3.4.rbl.interlinx.bc.ca has address 127.0.0.2

greatunwashed_host $ host 1.2.3.4.rbl.interlinx.bc.ca.
1.2.3.4.rbl.interlinx.bc.ca has address 127.0.0.2

As you can see, it took a complete server restart for the greatunwashed
view to get the zone update.

Is this expected behavior or a (known?) bug?

Cheers,
b.
