kasp-max-types-per-name (named2.conf.in):
An unsigned zone with RR type count on a name right below the
configured limit. Then sign the zone using KASP. Adding a RRSIG would
push it over the RR type limit per name. Signing should fail, but
the server should not crash, nor end up in infinite resign-attempt loop.
kasp-max-records-per-type-dnskey (named1.conf.in):
Test with low max-record-per-rrset limit and a DNSSEC policy requiring
more than the limit. Signing should fail.
kasp-max-types-per-name (named1.conf.in):
Each RRSIG(covered type) is counted as an individual RR type. Test the
corner case where a signed zone, which is just below the limit-1,
adds a new type - doing so would trigger signing for the new type and
thus increase the number of "types" by 2, pushing it over the limit
again.
Add two new masterformat tests that use signing. In the case of
'under-limit-kasp', the signing will keep the number of records in the
RRset under the limit. In the case of 'on-limit-kasp', the signing
will push the number of records in the RRset over the limit, because
of the added RRSIG record.
Send a recursive query for a large number of RRsets, which should
fail when using the default max-types-per-name setting of 100, but
succeed when the cap is disabled.
Previously, the number of RR types for a single owner name was limited
only by the maximum number of the types (64k). As the data structure
that holds the RR types for the database node is just a linked list, and
there are places where we just walk through the whole list (again and
again), adding a large number of RR types for a single owner named with
would slow down processing of such name (database node).
Add a configurable limit to cap the number of the RR types for a single
owner. This is enforced at the database (rbtdb, qpzone, qpcache) level
and configured with new max-types-per-name configuration option that
can be configured globally, per-view and per-zone.
Send a recursive query for a large (2500 record) RRset, which should
fail when using the default max-records-per-type setting of 100, but
succeed when the cap is disabled.
Add two new masterformat tests - the 'huge' zone fits within the ns1
limit and loads on the primary ns1 server, but must not transfer to the
ns2 secondary, and the 'uber' zone should not even load on the primary
ns1 server.
Previously, the number of RRs in the RRSets were internally unlimited.
As the data structure that holds the RRs is just a linked list, and
there are places where we just walk through all of the RRs, adding an
RRSet with huge number of RRs inside would slow down processing of said
RRSets.
Add a configurable limit to cap the number of the RRs in a single RRSet.
This is enforced at the database (rbtdb, qpzone, qpcache) level and
configured with new max-records-per-type configuration option that can
be configured globally, per-view and per-zone.
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'.
When in -4 mode check that "IPv6 disabled and no IPv4 primaries"
is logged and when in -6 mode check that "IPv4 disabled and no IPv6
primaries" is logged.
The times it takes to run tests CI vary significantly enough
that it makes hypothesis test reach their deadlines and fail randomly
marking the tests as flaky.
This commit disables the deadlines when running in CI.
The most important being `dns_names` that generates dns.name.Name
objects based on given paramaters.
No guarantees are given when it comes the uniformity of generated
samples, however it plays nicely with the hypothesis' shrinking
algorithm.
Once we use hypothesis more widely (in at least one more test) this file
should be moved for it to be reused easily.
Check for more rcodes and various properties needed in the wildcard
test. Add a `name` module for various dns.name.Name operations (with
`prepend_label` function only now).
Expose `timeout` as a parameter of `query.tcp`/`query.udp`.

An obscured DNSKEY RRset at a delegation was incorrectly added to
the NSEC/NSEC3 type bit map leading to zone verification failures.
This adds such a RRset to the test zone.
DNSSEC only works when DNSKEYs are self signed. This only occurs
when the DNSKEY RRset is at the apex. Cause dnssec-signzone to
fail if it attempts to sign an non-apex DNSKEY RRset.
The list isn't exactly maintained but it helped with some BIND history
tracking and is basically harmless so it might be worth holding onto it.
I have adapted the name to ASCII so IDN support won't be necessary.
The high-water allows administrators to better tune the recursive
clients limit without having to to poll the statistics channel in high
rates to get this number.
To avoid any escaping issues or messing with a language-specific format
when the variable has to be parsed, create a dedicated file for each
variable that is obtained from autoconf.
Make sure all initialization takes place in isctest.vars.__init__ and
export the initial env vars there. Remove the no longer needed env
fixture and use os.environ instead.
If OPENSSL_CONF is exported as an empty string, it will cause issues on
rhel9fips. Allow the environment variables to be set and exported, but
make sure to only export them if they have been set by the user.
The openssl config needs to be parsed for some tests that use SoftHSM2.
Rewrite the parsing to python and ensure the required variables are
properly set test-wide.
Provide a single point of access to all the variables used by tests. Use
a custom dict-like structure to access the underlying data without
making a copy. This allows the individual modules to update the contents
at runtime, which is used for some variables.
While this isn't required for pytest operation and execution of the
system test suite, it can be handy to allow test script development and
debugging. Especially setup scripts often source conf.sh and expect
environment variables to be loaded. If these scripts are executed
stand-alone, the environment variables need to be loaded from the python
package.
Remove conf.sh.in and move the environment variables into isctest/vars
python package. This enabled the removal of an ugly pytest hack which
loaded and parsed these variables from the environment.
qp and rbtdb produce stylistically different backup files. This
was causing the xferquota system test to fail. This has been
addressed by making the test independent of the stylistic differences.
