the parser could crash when "include" specified an empty string in place
of the filename. this has been fixed by returning ISC_R_FILENOTFOUND
when the string length is 0.
A 'tls' statement can be specified both for individual addresses
and for the whole list (as a default value when an individual
address doesn't have its own 'tls' set), just as it was done
before for the 'port' value.
Create a new function 'print_rawqstring()' to print a string residing
in a 'isc_textregion_t' type parameter.
Create a new function 'copy_string()' to copy a string from a
'cfg_obj_t' object into a 'isc_textregion_t'.
Add 'port' token to deprecated.conf. Also add options
'use-v4-udp-ports', 'use-v6-udp-ports', 'avoid-v4-udp-ports',
and 'avoid-v6-udp-ports'.
All of these should trigger warnings (except when deprecation warnings
are being ignored).
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.
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that the feature is obsolete and should not be used.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.
Add a new way to configure the preferred source address when talking to
remote servers such as primaries and parental-agents. This will
eventually deprecate options such as 'parental-source',
'parental-source-v6', 'transfer-source', etc.
Example of the new configuration:
parental-agents "parents" port 5353 \
source 10.10.10.10 port 5354 dscp 54 \
source-v6 2001:db8::10 port 5355 dscp 55 {
10.10.10.11;
2001:db8::11;
};
checkbashisms reports Bash-style ("==") string comparisons inside test/[
command:
possible bashism in bin/tests/system/checkconf/tests.sh line 105 (should be 'b = a'):
if [ $? == 0 ]; then echo_i "failed"; ret=1; fi
possible bashism in bin/tests/system/keyfromlabel/tests.sh line 62 (should be 'b = a'):
test $ret == 0 || continue
possible bashism in bin/tests/system/keyfromlabel/tests.sh line 79 (should be 'b = a'):
test $ret == 0 || continue
The checkbashisms script reports errors like this one:
script util/check-line-length.sh does not appear to have a #! interpreter line;
you may get strange results
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.
Check the new configuration option's syntax using the 'checkconf' system
test.
Check if the new option works by parsing DiG's output in the 'rpz'
system test.
The "max-zone-ttl" option should now be configured as part of
"dnssec-policy". The option with the same name in "zone" and
"options" is hereby flagged as deprecated, and its functionality
will be removed in a future release.
The "glue-cache" option was marked as deprecated by commit
5ae33351f2 (first released in BIND 9.17.6,
back in October 2020), so now obsolete that option, removing all code
and documentation related to it.
Note: this causes the glue cache feature to be permanently enabled, not
disabled.
The key lifetime should not be shorter than the time it costs to
introduce the successor key, otherwise keys will be created faster than
they are removed, resulting in a large key set.
The time it takes to replace a key is determined by the publication
interval (Ipub) of the successor key and the retire interval of the
predecessor key (Iret).
For the ZSK, Ipub is the sum of the DNSKEY TTL and zone propagation
delay (and publish safety). Iret is the sum of Dsgn, the maximum zone
TTL and zone propagation delay (and retire safety). The sign delay is
the signature validity period minus the refresh interval: The time to
ensure that all existing RRsets have been re-signed with the new key.
The ZSK lifetime should be larger than both values.
For the KSK, Ipub is the sum of the DNSKEY TTL and zone propagation
delay (and publish safety). Iret is the sum of the DS TTL and parent
zone propagation delay (and retire safety). The KSK lifetime should be
larger than both values.
The signatures-refresh should not near the signatures-validity value,
to prevent operational instability. Same is true when checking against
signatures-validity-dnskey.
bad-ksk-without-zsk.conf only has a ksk defined without a
matching zsk for the same algorithm.
bad-zsk-without-ksk.conf only has a zsk defined without a
matching ksk for the same algorithm.
bad-unpaired-keys.conf has two keys of different algorithms
one ksk only and the other zsk only
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.
This sets as many server options as possible at once to detect
cut-and-paste bugs when implementing new server options in peer.c.
Most of the accessor functions are similar and it is easy to miss
updating a macro name or structure element name when adding new
accessor functions.
checkconf/setup.sh is there to minimise the difference to branches
with optional server options where the list is updated at runtime.
This commit ensure that the 'tls' name specified in the 'primaries'
clause of a 'zone' statement is a valid one.
Prior to that such a name would be silently accepted, leading to
silent XFRs-via-TLS failures.
This commit extends the 'doth' system test to verify that the new
extended 'allow-transfer' option syntax featuring 'port' and
'transport' parameters is supported and works as expected. That is, it
restricts the primary server to allow zone transfers only via XoT.
Additionally to that, it extends the 'checkonf' test with more
configuration file examples featuring the new syntax.
This commit disables the unused 'tls' clause options. For these some
backing code exists, but their values are not really used anywhere,
nor there are sufficient syntax tests for them.
These options are only disabled temporarily, until TLS certificate
verification gets implemented.
In the 9.17.19 release "tls" statements verification code was
added. The code was too strict and assumed that every such a statement
should have both "cert-file" and "key-file" specified. This turned out
to be a regression, as in some cases we plan to use the "tls"
statement to specify TLS connection parameters.
This commit fixes this behaviour; now a "tls" statement should either
have both "cert-file" and "key-file" specified, or both should be
omitted.
Duplicate catalog zone entries caused an assertion failure
in named during configuration. This is now a soft error
that is detected earlier by named and also by named-checkconf.
Replace most "master/slave" terminology in tests with the preferred
"primary/secondary", with the following exceptions:
- When testing the old syntax
- When master is used in master file and master file format terms
- When master is used in hostmaster or postmaster terms
- When master used in legacy domain names (for example in dig.batch)
- When there is no replacement (for example default-masters)
