Adds a new option to named-checkconf, -i. If set, named-checkconf
will not warn you about deprecated options. This allows people
to use named-checkconf in automated deployment precoesses where an
operator only cares if their conf is valid, even if it is not optimal.
This was added as a request as part of introducing a policy on
removing named.conf options.
- revise mapping of search terms to database types to match the
GeoIP2 schemas.
- open GeoIP2 databases when starting up; close when shutting down.
- clarify the logged error message when an unknown database type
is configured.
- add new geoip ACL subtypes to support searching for continent in
country databases.
- map geoip ACL subtypes to specific MMDB database queries.
- perform MMDB lookups based on subtype, saving state between
queries so repeated lookups for the same address aren't necessary.
- "--with-geoip" is used to enable the legacy GeoIP library.
- "--with-geoip2" is used to enable the new GeoIP2 library
(libmaxminddb), and is on by default if the library is found.
- using both "--with-geoip" and "--with-geoip2" at the same time
is an error.
- an attempt is made to determine the default GeoIP2 database path at
compile time if pkg-config is able to report the module prefix. if
this fails, it will be necessary to set the path in named.conf with
geoip-directory
- Makefiles have been updated, and a stub lib/dns/geoip2.c has been
added for the eventual GeoIP2 search implementation.
The ax_check_openssl m4 macro used OPENSSL_INCLUDES. Rename the
subst variable to OPENSSL_CFLAGS and wrap AX_CHECK_OPENSSL() in
action-if-not-found part of PKG_CHECK_MODULE check for libcrypto.
The json-c have previously leaked into the global namespace leading
to forced -I<include_path> for every compilation unit using isc/xml.h
header. This MR fixes the usage making the caller object opaque.

- managed-keys is now deprecated as well as trusted-keys, though
it continues to work as a synonym for dnssec-keys
- references to managed-keys have been updated throughout the code.
- tests have been updated to use dnssec-keys format
- also the trusted-keys entries have been removed from the generated
bind.keys.h file and are no longer generated by bindkeys.pl.
- trusted-keys is now flagged as deprecated, but still works
- managed-keys can be used to configure permanent trust anchors by
using the "static-key" keyword in place of "initial-key"
- parser now uses an enum for static-key and initial-key keywords
Since 2008, the cleaning-interval timer has been documented as
"effectively obsolete" and disabled in the default configuration with
a comment saying "now meaningless".
This change deletes all the code that implements the cleaning-interval
timer, except for the config parser in whcih it is now explicitly
marked as obsolete.
I have verified (using the deletelru and deletettl cache stats) that
named still cleans the cache after this change.
- options that were flagged as obsolete or not implemented in 9.0.0
are now flagged as "ancient", and are a fatal error
- the ARM has been updated to remove these, along with other
obsolete descriptions of BIND 8 behavior
- the log message for obsolete options explicitly recommends removal
Add a new libisccfg function, cfg_pluginlist_foreach(), which allows an
arbitrary callback to be invoked for every "plugin" stanza present in a
configuration object. Use this function for both loading plugins and
checking their configuration in order to reduce duplication of
configuration processing code present in bin/named/server.c and
lib/bind9/check.c.
- "hook" is now used only for hook points and hook actions
- the "hook" statement in named.conf is now "plugin"
- ns_module and ns_modlist are now ns_plugin and ns_plugins
- ns_module_load is renamed ns_plugin_register
- the mandatory functions in plugin modules (hook_register,
hook_check, hook_version, hook_destroy) have been renamed
- make some cfg-parsing functions global so they can be run
from filter-aaaa.so
- add filter-aaaa options to the hook module's parser
- mark filter-aaaa options in named.conf as obsolete, remove
from named and checkconf, and update the filter-aaaa test not to
use checkconf anymore
- remove filter-aaaa-related struct members from dns_view
- allow multiple "hook" statements at global or view level
- add "optional bracketed text" type for optional parameter list
- load hook module from specified path rather than hardcoded path
- add a hooktable pointer (and a callback for freeing it) to the
view structure
- change the hooktable functions so they no longer update ns__hook_table
by default, and modify PROCESS_HOOK so it uses the view hooktable, if
set, rather than ns__hook_table. (ns__hook_table is retained for
use by unit tests.)
- update the filter-aaaa system test to load filter-aaaa.so
- add a prereq script to check for dlopen support before running
the filter-aaaa system test
not yet done:
- configuration parameters are not being passed to the filter-aaaa
module; the filter-aaaa ACL and filter-aaaa-on-{v4,v6} settings are
still stored in dns_view
Sometimes it is useful to set a 'floor' on the TTL for records
to be cached. Some sites like to use ridiculously low TTLs for
some reason, and that often is not compatible with slow links.

Use a zone's 'type' field instead of the value of its DNS_ZONEOPT_MIRROR
option for checking whether it is a mirror zone. This makes said zone
option and its associated helper function, dns_zone_mirror(), redundant,
so remove them. Remove a check specific to mirror zones from
named_zone_reusable() since another check in that function ensures that
changing a zone's type prevents it from being reused during
reconfiguration.
Add a new zone type, CFG_ZONE_MIRROR, to libisccfg, in order to limit
the list of options which are considered valid for mirror zones. Update
the relevant configuration checks.
Contrary to what the documentation states, the "server-addresses"
static-stub zone option does not accept custom port numbers. Fix the
configuration type used by the "server-addresses" option to ensure
documentation matches source code. Remove a check_zoneconf() test which
is unnecessary with this fix in place.
This properly orders clearing the freed pointer and calling isc_refcount_destroy
as early as possible to have ability to put proper memory barrier when cleaning
up reference counting.
