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.
- this required modification to the code that generates grammar text for
the documentation, because the "dnssec-lookaside" option spanned more
than one line in doc/misc/options, so grepping out only the lines
marked "// obsolete" didn't remove the whole option. this commit adds
an option to cfg_test to print named.conf clauses only if they don't
have the obsolete, ancient, test-only, or not-yet-implemented flags
set.
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.
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.
Previously the autoconf script set sysconfdir to /etc and localstatedir to /var
if they were not explicitly set in the ./configure invocation. This MR reverts
the override and make it more in line with default and generally expected
autoconf behavior.
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.
