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)
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)
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)
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that the feature is obsolete and should not be used.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)
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)
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.
It would be too easy if we could just call sorted(). Thanks to zone
grammar the most important key "type" gets sorted near end, so we pull
it up to the top using a hack.
(cherry picked from commit 5c04e3c524)
It turns out the tree of dictionaries is not the best structure to
represent our grammar, unfortunatelly. The problem is that "zone" has
several context-dependent variants which change meaning of "zone" based
on inner field "type".
Redesigning the whole structure does not seem to be worth, so I settled
on this terrible hack.
(cherry picked from commit 0392144e99)
It produces the same format as cfg_test --grammar. The advantage is that
it allows to print any node in configuration the tree, not just whole
blocks.
(cherry picked from commit 190004e46c)
The utility detects statements which use the same name (e.g.
max-zone-ttl) but use different grammar in different contexts. These
typically need special case in docs.
(cherry picked from commit 8960d51aa3)
It transforms named.conf/rndc.conf grammar from text format into Python
dictionary. This allows granular access to grammar elements.
Beware: It heavity depens on cfg_test output format!
(cherry picked from commit df08982930)
It uses the same mechanism as all other grammars, but the file is named
differently to distinguish it from named.conf grammars.
(cherry picked from commit fb474de3ab)
The next commit is going to add parser for ISC configuration format.
To simplify the parser the grammar files in doc/misc are no longer
line-wrapped as handling it would make the grammar parser unnecessairly
complicated.
This affects visible output in the ARM, but in the end we are going to
replace the auto-generated .rst files with grammar pretty printed, so
formatting of these files does not matter in practical terms.
(cherry picked from commit 699570cdec)
After some back and forth, it was decidede to match the configuration
option with unbound ("so-reuseport"), PowerDNS ("reuseport") and/or
nginx ("reuseport").
(cherry picked from commit 7e71c4d0cc)
Previously, the option to enable kernel load balancing of the sockets
was always enabled when supported by the operating system (SO_REUSEPORT
on Linux and SO_REUSEPORT_LB on FreeBSD).
It was reported that in scenarios where the networking threads are also
responsible for processing long-running tasks (like RPZ processing, CATZ
processing or large zone transfers), this could lead to intermitten
brownouts for some clients, because the thread assigned by the operating
system might be busy. In such scenarious, the overall performance would
be better served by threads competing over the sockets because the idle
threads can pick up the incoming traffic.
Add new configuration option (`load-balance-sockets`) to allow enabling
or disabling the load balancing of the sockets.
(cherry picked from commit 85c6e797aa)
Commit 4ca74eee49 update the zone grammar
such that the zone statement is printed with the valid options per
zone type.
This commit is a follow-up, putting back the ZONE heading and adding
a note that these zone statements may also be put inside the view
statement.
It is tricky to actually print the zone statements inside
the view statement, and so we decided that we would add a note to say
that this is possible.
(cherry picked from commit 01b125ff05)
The named.conf grammar is exported to the manual via
doc/misc/rst-options.pl which is the ultimate source
for the non-grammar parts of the man page.
(cherry picked from commit ad5b0402c9)
Building BIND 9 with older version of BIND 9 installed would result in
build failure. Fix the last two remaining cases where <prog>_CFLAGS was
being used leading to wrong order of the build flags on the command line.
(cherry picked from commit 41a60a0e21)
the "zone" clause can be documented using, for instance,
`cfg_test --zonegrammar primary", which prints only
options that are valid in primary zones. this was not
the method being used when generating the named.conf
man page; instead, "zone" was documented with all possible
options, and no zone types at all.
this commit removes "zone" from the generic documentation
and adds include statements in named.conf.rst so that
correct zone grammars will be included in the man page.
(cherry picked from commit 4ca74eee49)
we now document zone type as either "primary" or "secondary",
omitting the old terms (though they are still accepted).
(cherry picked from commit 0bde07261b)
"masters" and "default-masters" are now flagged so they will
not be included in the named.conf man page, despite being
accepted as valid options by the parser for backward
compatibiility.
(cherry picked from commit 0e57fc160e)
There is little point of listing all of the obsolete RFCs. I think it is
more likely confuse people than to do anything useful.
(cherry picked from commit 9437ea08e1)
Replace the hard-coded paths for various BIND 9 files (configuration,
pid, etc.) in the man pages and ARM with compile-time values using the
sphinx-build replace system.
This is more complicated, because the restructured text specification
doesn't allow |substitions| inside ``code-blocks``, so for each specific
file we had to create own substition which is sub-optimal, but it is
only way how to do this without adding Sphinx extension.
(cherry picked from commit b42681c4e9)
Formerly parental-agents grammar was an exception and it did not
auto-generate itself from source code. From now on it is generated using
the same mechanism as other grammars.
For consistency with rest of the system, I've also renamed the grammar
file and the link anchors from "parentals" to "parental-agents".
Technically this is fixup for commit
0311705d4b.

(cherry picked from commit 34a3b35b08)
The missing `::` in the .rst files caused grammar section in docs to
render empty.
The `::` was accidentally removed in an unrelated commit
58bd26b6cf which was supposed to update
only copyright headers.
Fixes: #3120
(cherry picked from commit d975e6630f)
As far as I can tell, it is some leftover from the times when Sphinx
docs were introduced (commit 9fb6d11abb).
It seems like it is not referenced from anywhere.
This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.
