Having a value higher than signatures-validity does not make sense
and should be treated as a configuration error.
(cherry picked from commit c3d8932f79)
This commit improves the documentation on the ephemeral TLS
configuration and describes in more detail what is happening with TLS
configurations on reconfiguration in general.
(cherry picked from commit 1ab0f6d918)
"A parental agent is the entity that is allowed to change a zone's
delegation information" is untrue, because it is possible to use some
hidden server or a validating resolver.
Also the new text makes it more clear that named sends DS queries to
these servers.
(cherry picked from commit 604f8e7797)
these options control default timing of retries in the resolver
for experimental purposes; they are not known to useful in production
environments. they will be removed in the future; for now, we
only log a warning if they are used.
(cherry picked from commit 4aaa4f7dca)
The new :cve: Sphinx role takes a CVE number as an argument and creates
a hyperlink to the relevant ISC Knowledgebase document that might have
more up-to-date or verbose information than the relevant release note.
This makes reaching ISC Knowledgebase pages directly from the release
notes easier.
Make all CVE references in the release notes use the new Sphinx role.
(cherry picked from commit 41b857e567)
The dnssec-must-be-secure feature was added in the early days of BIND 9
and DNSSEC and it makes sense only as a debugging feature.
Remove the feature to simplify the code.
(cherry picked from commit 9e0b348a2b)
Add the text "TTL-style unit suffixes or ISO 8601 duration formats",
just like we do at other places that are duration option types.
Also, in the dnssec-policy "keys" example, use a TTL-style unit too.
(cherry picked from commit b5a757c452)
There's a statement that says: "Here is an example (for illustration
purposes only) of some possible entries in a [keys] list:", and that
links to the wrong "keys" statement (it links to the TSIG keys section).
Remove the reference, as we are already in the right section.
(cherry picked from commit 07c70ea2bd)
these options concentrate zone maintenance actions into
bursts for the benefit of servers with intermittent connections.
that's no longer something we really need to optimize.
(cherry picked from commit eeeccec67c)
The reference manual doesn't document all the available resolver
statistics counters. Add information about the missing counters.
(cherry picked from commit 08ebf39d1e)
After the dns_xfrin was changed to use network manager, the maximum
global (max-transfer-time-in) and idle (max-transfer-idle-in) times for
incoming transfers were turned inoperational because of missing
implementation.
Restore this functionality by implementing the timers for the incoming
transfers.
(cherry picked from commit d2377f8e04)
Remove the reference to setting the DF-flag as we don't do that right
now. Rephrase the paragraph that the default value should not be
causing fragmentation.
(cherry picked from commit 61f276d5a4)
With a newline before the :suppress_grammar: directive, it wasn't
actually interpreted as a directive, but rather as node content.
Therefore, the directive was ignored and the grammar was incorrectly
printed out.
(cherry picked from commit 36a5c098bd)
These options and zone type were created to address the
SiteFinder controversy, in which certain TLD's redirected queries
rather than returning NXDOMAIN. since TLD's are now DNSSEC-signed,
this is no longer likely to be a problem.
The deprecation message for 'type delegation-only' is issued from
the configuration checker rather than the parser. therefore,
isccfg_check_namedconf() has been modified to take a 'nodeprecate'
parameter to suppress the warning when named-checkconf is used with
the command-line option to ignore warnings on deprecated options (-i).
(cherry picked from commit 2399556bee)
Deprecate the use of "port" when configuring query-source(-v6),
transfer-source(-v6), notify-source(-v6), parental-source(-v6),
etc. Also deprecate use-{v4,v6}-udp-ports and avoid-{v4,v6}udp-ports.
(cherry picked from commit 470ccbc8ed)
limit the number of simultaneous DNS UPDATE events that can be
processed by adding a quota for update and update forwarding.
this quota currently, arbitrarily, defaults to 100.
also add a statistics counter to record when the update quota
has been exceeded.
(cherry picked from commit 7c47254a14)
DSCP has not been fully working since the network manager was
introduced in 9.16, and has been completely broken since 9.18.
This seems to have caused very few difficulties for anyone,
so we have now marked it as obsolete and removed the
implementation.
To ensure that old config files don't fail, the code to parse
dscp key-value pairs is still present, but a warning is logged
that the feature is obsolete and should not be used. Nothing is
done with configured values, and there is no longer any
range checking.
(cherry picked from commit 916ea26ead)
This option was deprecated in commit 19352dd187 but at that time
we didn't mark it deprecated in the ARM reference.
(cherry picked from commit 13a16c1f4d)
It was possible to set operating system limits (RLIMIT_DATA,
RLIMIT_STACK, RLIMIT_CORE and RLIMIT_NOFILE) from named.conf. It's
better to leave these untouched as setting these is responsibility of
the operating system and/or supervisor.
Deprecate the configuration options and remove them in future BIND 9
release.
(cherry picked from commit 379929e052)
For the prefetch "trigger" parameter ARM states that when a cache
record with a lower TTL value is encountered during query processing,
it is refreshed. But in reality, the record is refreshed when the TTL
value is lower or equal to the configured "trigger" value.
Fix the documentation to make it match with with the code.
(cherry picked from commit ef344b1f52)
This is hopefully end of duplication. This batch did not cause clashes
in Sphinx but it was pointless nonetheless as we have auto-generated
anchors for all statements.
(cherry picked from commit 137e0f4e0e)
Adapted for v9_18 branch by doing cleanup also in
notes/notes-9.18.0.rst.
Some statement names like "allow-query" had manually defined link anchor
_allow-query and also implicit anchor created by
.. namedconf:statement:: syntax. This causes warnings if a ambiguous
reference is made using :any:`allow-query` syntax.
Remove (hopefully all) manually defined anchors which pointed to
identical place as the implicit anchor. This allows :any: to work.
In rare cases where manual anchor points to descriptive text separated
from statement definition the reference was disamguated by replacing
:any:`notify` with :ref:`notify` (for manual anchor)
vs. :namedconf:ref:`notify` (for statement definition).
Please note that `options` statement is a trap: It is ambiguous even
without manual anchor because rndc.conf has its own `options`. Use
:namedconf:ref:`options` vs. :rndcconf:ref:`options` to select
appropriate target.
(cherry picked from commit 9a7c2b370e)
Make documentation building successful even on RHEL9 sphinx 3.4.3. It
does not like case-insensitive matching of terms, so provide lowercase
text description with Uppercase word reference.
(cherry picked from commit bc6c6b1184)
Add more text about the importance of properly securing the statistics
channel and what is and what is not considered a security vulnerability.
(cherry picked from commit 6869c98d36)
the "random-device" option was made non-functional in 9.13, but was
not marked as obsolete at that time. this is now fixed; configuring
"random-device" will trigger a warning.
