The keyword 'unlimited' can be used instead of PT0S which means the
same but is more comprehensible for users.
Also fix some redundant "none" parameters in the kasp test.
Clarify in the ARM that TTL-style options can also now take ISO
8601 durations.
Mention the built-in dnssec policies "default" and "none". Mention
that "none" is the default.
Add a file documenting the default dnssec-policy configuration options.
Fix dnssec-policy syntax in ARM (dnssec-policy.grammar.xml).
When doing rollover in a timely manner we need to have access to the
relevant kasp configured durations.
Most of these are simple get functions, but 'dns_kasp_signdelay'
will calculate the maximum time that is needed with this policy to
resign the complete zone (taking into account the refresh interval
and signature validity).
Introduce parent-propagation-delay, parent-registration-delay,
parent-ds-ttl, zone-max-ttl, zone-propagation-delay.
This commit introduces the initial `dnssec-policy` configuration
statement. It has an initial set of options to deal with signature
and key maintenance.
Add some checks to ensure that dnssec-policy is configured at the
right locations, and that policies referenced to in zone statements
actually exist.
Add some checks that when a user adds the new `dnssec-policy`
configuration, it will no longer contain existing DNSSEC
configuration options. Specifically: `inline-signing`,
`auto-dnssec`, `dnssec-dnskey-kskonly`, `dnssec-secure-to-insecure`,
`update-check-ksk`, `dnssec-update-mode`, `dnskey-sig-validity`,
and `sig-validity-interval`.
Test a good kasp configuration, and some bad configurations.
It was found that NSEC Aggressive Caching has a significant performance impact
on BIND 9 when used as recursor. This commit disables the synth-from-dnssec
configuration option by default to provide immediate remedy for people running
BIND 9.12+. The NSEC Aggressive Cache will be enabled again after a proper fix
will be prepared.
The stale RR types are now printed with '#'. This used to be the
prefix for RR types that were marked ancient, but commit
df50751585 changed the meaning. It is
probably better to keep '#' for stale RR types and introduce a new
prefix for reintroducing ancient type stat counters.
In the ARM section about RPZ, add text explicitly stating that ACLs take
precedence over RPZ to prevent users from expecting RPZ actions to be
applied to queries coming from clients which are not permitted access to
the resolver by ACLs.
The 'managed-keys' (and 'trusted-keys') options have been deprecated
by 'dnssec-keys'. Some documentation references to 'managed-keys'
had not yet been marked or noted as such.
Using atomic_int_fast64_t variables with atomic functions on x86 does
not cause Visual Studio to report build errors, but such operations
yield useless results. Since the isc_stat_t type is unconditionally
typedef'd to atomic_int_fast64_t, any code performing atomic operations
on isc_stat_t variables is broken in x86 Windows builds. Fix by using
the atomic_int_fast32_t type for isc_stat_t in x86 Windows builds.
- change references to trusted-keys to dnssec-keys with static-key
- rebuild doc/misc/options and other generated grammar doc
- add a "see MANAGED-KEYS" note when building named.conf.docbook
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.
in the "refactor tcpquota and pipeline refs" commit, the counting
of active interfaces was tightened in such a way that named could
fail to listen on an interface if there were more interfaces than
tcp-clients. when checking the quota to start accepting on an
interface, if the number of active clients was above zero, then
it was presumed that some other client was able to handle accepting
new connections. this, however, ignored the fact that the current client
could be included in that count, so if the quota was already exceeded
before all the interfaces were listening, some interfaces would never
listen.
we now check whether the current client has been marked active; if so,
then the number of active clients on the interface must be greater
than 1, not 0.

(cherry picked from commit cae79e1bab)
More specifically: ignore configured trusted and managed keys that
match a disabled algorithm. The behavioral change is that
associated responses no longer SERVFAIL, but return insecure.
