Subject: [PATCH] merge dyndb
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
4224. [func] Added support for "dyndb", a new interface for loading
zone data from an external database, developed by
Red Hat for the FreeIPA project.
DynDB drivers fully implement the BIND database
API, and are capable of significantly better
performance and functionality than DLZ drivers,
while taking advantage of advanced database
features not available in BIND such as multi-master
replication.
Thanks to Adam Tkac and Petr Spacek of Red Hat.

+To use the Dynamic DB sample driver, run named and check the log.
+
+ $ cd testing
+ $ named -gc named.conf
+
+You should be able to see something like:
+
+zone test/IN: loaded serial 0
+zone arpa/IN: loaded serial 0
+
+This means that the sample driver created empty zones "test." and
+"arpa." as defined by "arg" parameters in named.conf.
+
+$ dig @localhost test.
+
+should work as usual and you should be able to see the dummy zone with
+NS record pointing to the zone apex and A record with 127.0.0.1:
+
+;; ANSWER SECTION:
+test. 86400 IN A 127.0.0.1
+test. 86400 IN NS test.
+test. 86400 IN SOA test. test. 0 28800 7200 604800 86400
+
+This driver creates two empty zones and allows query/transfer/update to
+all IP addresses for demonstration purposes.
+
+The driver wraps the RBT database implementation used natively by BIND,
+and modifies the addrdataset() and substractrdataset() functions to do
+additional work during dynamic updates.
+
+A dynamic update modifies the target zone as usual. After that, the
+driver detects whether the modified RR was of type A or AAAA, and if so,
+attempts to appropriately generate or delete a matching PTR record in
+one of the two zones managed by the driver.
+
+E.g.:
+
+$ nsupdate
+> update add a.test. 300 IN A 192.0.2.1
+> send
+
+will add the A record
+a.test. 300 IN A 192.0.2.1
+
+and also automatically generate the PTR record
+1.2.0.192.in-addr.arpa. 300 IN PTR a.test.
+
+AXFR and RR deletion via dynamic updates should work as usual. Deletion
+of a type A or AAAA record should delete the corresponding PTR record
+too.
+
+The zone is stored only in memory, and all changes will be lost on
+reload/reconfig.
+
+Hints for code readers:
+- Driver initialization starts in driver.c: dyndb_init() function.
+- New database implementation is registered by calling dns_db_register()
+ and passing a function pointer to it. This sample uses the function
+ create_db() to initialize the database.
+- Zones are created later in instance.c: load_sample_instance_zones().
+- Database entry points are in structure db.c: dns_dbmethods_t
+ sampledb_methods
+- sampledb_methods points to an implementation of the database interface.
+ See the db.c: addrdataset() implementation and look at how the RBT
+ database instance is wrapped into an additional layer of logic.

+ <title>DynDB (Dynamic Database)</title>
+ <para>
+ DynDB is an extension to BIND 9 which, like DLZ
+ (see <xref linkend="dlz-info"/>), allows zone data to be
+ retrieved from an external database. Unlike DLZ, a DynDB module
+ provides a full-featured BIND zone database interface. Where
+ DLZ translates DNS queries into real-time database lookups,
+ resulting in relatively poor query performance, and is unable
+ to handle DNSSEC-signed data due to its limited API, a DynDB
+ module can pre-load an in-memory database from the external
+ data source, providing the same performance and functionality
+ as zones served natively by BIND.
+ </para>
+ <para>
+ A DynDB module supporting LDAP has been created by Red Hat
+ and is available from
+ <ulink url="https://fedorahosted.org/bind-dyndb-ldap/"

+ A DynDB database is configured with a <command>dyndb</command>
+ statement in <filename>named.conf</filename>:
+ </para>
+ <screen>
+ dyndb example "driver.so" {
+ <replaceable>parameters</replaceable>
+ };
+ </screen>
+ <para>
+ The file <filename>driver.so</filename> is a DynDB module which
+ implements the full DNS database API. Multiple
+ <command>dyndb</command> statements can be specified, to load
+ different drivers or multiple instances of the same driver.
+ Zones provided by a DynDB module are added to the view's zone
+ table, and are treated as normal authoritative zones when BIND
+ is responding to queries. Zone configuration is handled internally
+ by the DynDB module.
+ </para>
+ <para>
+ The <replaceable>parameters</replaceable> are passed as an opaque
+ string to the DynDB module's initialization routine. Configuration
+ syntax will differ depending on the driver.
+ </para>

+ <sect2>
+ <title>Sample DynDB Module</title>
+ <para>
+ For guidance in implementation of DynDB modules, the directory
+ <filename>bin/tests/system/dyndb/driver</filename>.
+ contains a basic DynDB module.
+ The example sets up two zones, whose names are passed
+ to the module as arguments in the <command>dyndb</command>
+ statement:
+ </para>
+ <screen>
+ dyndb sample "sample.so" { example.nil. arpa. };
+ </screen>
+ <para>
+ In the above example, the module is configured to create a zone
+ "example.nil", which can answer queries and AXFR requests, and
+ accept DDNS updates. At runtime, prior to any updates, the zone
+ contains an SOA, NS, and a single A record at the apex:
+ </para>
+ <screen>
+ example.nil. 86400 IN SOA example.nil. example.nil. (
+ 0 28800 7200 604800 86400
+ )
+ example.nil. 86400 IN NS example.nil.
+ example.nil. 86400 IN A 127.0.0.1
+ </screen>
+ <para>
+ When the zone is updated dynamically, the DynDB module will determine
+ whether the updated RR is an address (i.e., type A or AAAA) and if
+ so, it will automatically update the corresponding PTR record in a
+ reverse zone. (Updates are not stored permanently; all updates are
+ lost when the server is restarted.)
+ </para>
+ </sect2>
