- 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.
- added new 'validate-except' option, which configures an NTA with
expiry of 0xffffffff. NTAs with that value in the expiry field do not
expire, are are not written out when saving the NTA table and are not
dumped by rndc secroots
Add a new slave-only boolean configuration option, "mirror", along with
its corresponding dns_zoneopt_t enum and a helper function for checking
whether that option was set for a given zone. This commit does not
introduce any behavior changes yet.
