add database API methods needed for loading rdatasets into memory
(currentversion, beginload, endload), plus the methods used by
zone_postload() for zone consistency checks (getoriginnode, find,
findnode, findrdataset, attachnode, detachnode, deletedata).
the QP trie doesn't support the find callback mechanism available
in dns_rbt_findnode() which allows examination of intermediate nodes
while searching, so the detection of wildcard and delegation nodes
is now done by scanning QP chains after calling dns_qp_lookup().
Note that the lookup in previous_closest_nsec() cannot return
ISC_R_NOTFOUND. In RBTDB, we checked for this return value and
ovewrote the result with ISC_R_NOMORE if it occurred. In the
qpzone implementation, we insist that this return value cannot happen.
dns_qp_lookup() would only return ISC_R_NOTFOUND if we asked for a
name outside the zone's authoritative domain, and we never do that
when looking up a predecessor NSEC record.
named-checkzone is now able to load a zone and check it for errors,
but cannot dump it.
dohpath is specfied in draft-ietf-add-svcb-dns and has a value
of 7. It must be a relative path (start with a /), be encoded
as UTF8 and contain the variable dns ({?dns}).
The original sscanf processing allowed for a number of syntax errors
to be accepted. This included missing the closing brace in
${modifiers}
Look for both comma and right brace as intermediate seperators as
well as consuming the final right brace in the sscanf processing
for ${modifiers}. Check when we got right brace to determine if
the sscanf consumed more input than expected and if so behave as
if it had stopped at the first right brace.
$GENERATE uses 'int' for its computations and some constructions
can overflow values that can be represented by an 'int' resulting
in undefined behaviour. Detect these conditions and return a
range error.
the line "$GENERATE 19-28/2147483645 $ CNAME x" should generate
a single CNAME with the owner "19.example.com", but prior to the
overflow bug it generated several CNAMEs, half of them with large
negative values.
we now test for the bugfix by using "named-checkzone -D" and
grepping for a single CNAME in the output.
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.
Add tests to the nsupdate system test to make sure that CDS and/or
CDNSKEY that match an algorithm in the DNSKEY RRset are allowed. Also
add tests that updates are rejected if the algorithm does not match.
Remove the now redundant test cases from the dnssec system test.
Update the checkzone system test: Change the algorithm of the CDS and
CDNSKEY records so that the zone is still rejected.
DS records only belong at delegation points and if present
at the zone apex are invariably the result of administrative
errors. Additionally they can't be queried for with modern
resolvers as the parent servers will be queried.
