Changed the default value for 'allow-transfer' to 'none'; zone
transfers now require explicit authorization.
Updated all system tests to specify an allow-transfer ACL when needed.
Revised the ARM to specify that the default is 'none'.
We were missing a test where a single owner name would have multiple
types with a different case. The generated RRSIGs and NSEC records will
then have different case than the signed records and message parser have
to cope with that and treat everything as the same owner.
All changes in this commit were automated using the command:
shfmt -w -i 2 -ci -bn . $(find . -name "*.sh.in")
By default, only *.sh and files without extension are checked, so
*.sh.in files have to be added additionally. (See mvdan/sh#944)
The old name "common" clashes with the convention of system test
directory naming. It appears as a system test directory, but it only
contains helper files.
To reduce confusion and to allow automatic detection of issues with
possibly missing test files, rename the helper directory to "_common".
The leading underscore indicates the directory is different and the its
name can no longer be confused with regular system test directories.
The dnssec system test has some tests that use auto-dnssec. Update
these tests to make use of dnssec-policy.
Remove any 'rndc signing -nsec3param' commands because with
dnssec-policy you set the NSEC3 parameters in the configuration.
Remove now duplicate tests that checked if CDS and CDNSKEY RRsets
are signed with KSK only (the dnssec-dnskey-kskonly option worked
in combination with auto-dnssec).
Also remove the publish-inactive.example test case because such
use cases are no longer supported (only with manual signing).
The auto-nsec and auto-nsec3 zones need to use an alternative
algorithm because duplicate lines in dnssec-policy/keys are ignored.
The 'update-nsec3.example' requires to be DNSSEC maintained via
dynamic update. Commit 03b22983cd20cec51ad8b9f25f2e7d0e472dc79c adds
checks to make sure the raw zone is not signed. So the test case neesd
to be updated to allow for DNSSEC maintenance.
Completely remove the TKEY Mode 2 (Diffie-Hellman Exchanged Keying) from
BIND 9 (from named, named.conf and all the tools). The TKEY usage is
fringe at best and in all known cases, GSSAPI is being used as it should.
The draft-eastlake-dnsop-rfc2930bis-tkey specifies that:
4.2 Diffie-Hellman Exchanged Keying (Deprecated)
The use of this mode (#2) is NOT RECOMMENDED for the following two
reasons but the specification is still included in Appendix A in case
an implementation is needed for compatibility with old TKEY
implementations. See Section 4.6 on ECDH Exchanged Keying.
The mixing function used does not meet current cryptographic
standards because it uses MD5 [RFC6151].
RSA keys must be excessively long to achieve levels of security
required by current standards.
We might optionally implement Elliptic Curve Diffie-Hellman (ECDH) key
exchange mode 6 if the draft ever reaches the RFC status. Meanwhile the
insecure DH mode needs to be removed.
The perl modifation code for keyless.example was not deterministic
(/NXT/ matched part of signature) resulting in different error
strings being returned. Replaced /NXT/ with /A RRSIG NSEC/ and
updated expected error string,
Prime the cache with a negative cache DS entry then make a query for
name beneath that entry. This will cause the DS entry to be retieved
as part of the validation process. Each RRset in the ncache entry
will be validated and the trust level for each will be updated.
- Removed all code that only runs under CYGWIN, and made all
code that doesn't run under CYGWIN non-optional.
- Removed the $TP variable which was used to add optional
trailing dots to filenames; they're no longer optional.
- Removed references to pssuspend and dos2unix.
- No need to use environment variables for diff and kill.
- Removed uses of "tr -d '\r'"; this was a workaround for
a cygwin regex bug that is no longer needed.
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.
Most of the test zones in the dnssec system test can be verified.
Use -z when only a single key is being used so that the verifier
knows that only a single key is in use.
The method used to generate a test zone with multiple NSEC and
NSEC3 chains was incorrect. Multiple calls to dnssec-signzone
with multiple parameters is not additive. Extract the chain on
each run then add them to the final signed zone instance.
The $SYSTEMTESTTOP shell variable if often set to .. in various shell
scripts inside bin/tests/system/, but most of the time it is only
used one line later, while sourcing conf.sh. This hardly improves
code readability.
$SYSTEMTESTTOP is also used for the purpose of referencing
scripts/files living in bin/tests/system/, but given that the
variable is always set to a short, relative path, we can drop it and
replace all of its occurrences with the relative path without adversely
affecting code readability.
this changes most visble uses of master/slave terminology in tests.sh
and most uses of 'type master' or 'type slave' in named.conf files.
files in the checkconf test were not updated in order to confirm that
the old syntax still works. rpzrecurse was also left mostly unchanged
to avoid interference with DNSRPS.
as "type primary" is preferred over "type master" now, it makes
sense to make "primaries" available as a synonym too.
added a correctness check to ensure "primaries" and "masters"
cannot both be used in the same zone.
Windows systems do not allow a trailing period in file names while Unix
systems do. When BIND system tests are run, the $TP environment
variable is set to an empty string on Windows systems and to "." on Unix
systems. This environment variable is then used by system test scripts
for handling this discrepancy properly.
In multiple system test scripts, a variable holding a zone name is set
to a string with a trailing period while the names of the zone's
corresponding dlvset-* and/or dsset-* files are determined using
numerous sed invocations like the following one:
dlvsets="$dlvsets dlvset-`echo $zone |sed -e "s/.$//g"`$TP"
In order to improve code readability, use zone names without trailing
periods and replace sed invocations with variable substitutions.
To retain local consistency, also remove the trailing period from
certain other zone names used in system tests that are not subsequently
processed using sed.
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.
the occluded-key test creates both a KEY and a DNSKEY. the second
call to dnssec-keygen calls dns_dnssec_findmatchingkeys(), which causes
a spurious warning to be printed when it sees the type KEY record.
this should be fixed in dnssec.c, but the meantime this change silences
the warning by reversing the order in which the keys are created.
- add CHANGES note
- update copyrights and license headers
- add -j to the make commands in .gitlab-ci.yml to take
advantage of parallelization in the gitlab CI process
