'addr', 'ckresult' and 'drop' should return 0 rather than 1 after
calling 'setret' as the error has been logged and these functions
are not expect to fail.
pytest should not schedule dupsigs and keymgr2kasp system tests removed
in BIND 9 mainline but still present in BIND 9 baseline version
(v9.19.15). (Can be dropped once the v9.19.16 tag is present.)
In #3381 (and #3385), we committed a backward-incompatible change to
BIND 9.19.5, 9.18.7, and 9.16.33, explicitly requiring "inline-signing"
for every "dnssec-policy".
We did this backward-incompatible change deliberately, knowing the
consequences for users and their configurations. But if we didn't, say,
we were unaware this is a backward-incompatible change and fixed failing
systems test by "tweaking a knob to make the CI pass", we would not have
a second look before the change hits user configurations.
"cross-version-config-tests" CI job is such a second look. It will run
system tests from the latest release tag specific to the particular
branch (e.g., v9.19.12 for the "main" branch) with BIND 9 binaries from
the current "HEAD" (the future v9.19.13). This Frankenstein build gets
conceived by altering the "TOP_BUILDDIR" variable in
"bin/tests/system/conf.sh".
Caveats:
- Only system test configurations are tested; no actual test code is
run.
- Problems with namedN.conf configurations are not identified.
When backward-incompatible change is introduced, the CI job is expected
to fail. If the change is deliberate, the job will keep failing until
the version with the backward-incompatible change is tagged, and the
minor version in configure.ac is bumped.
- Rework key checks to not require 'engine' tag, private key
is valid with 'label' tag alone
- Fix _fromlabel() functions to work with engine == NULL
- Update dst__openssl_fromlabel_engine() to do provider lookup
only when engine is not set
The OpenSSL man page examples used the NIST curve names which
are supported. But when querying the name, the native OpenSSL
name is returned. Use these names to pass curve type checks for
engine/provider objects.
The setup.pl script has been replaced with static BIND configurations,
and in the course of this change, the unused ns1 server was removed.
This enhancement has greatly improved the overall test's readability.
The shell version of the test was completed only after all DNS zone
updates were sent, even if the BIND server crashed while processing
them, leading to prolonged execution and potential hang in the CI
environment. The Python rewrite of the test ensures that DNS update
tasks finish within five minutes of starting, irrespective of a BIND
crash possibility or DNS zone updates not finishing in time.
Lower the size requirement for the dnstap output file produced during
the "dnstap" system test from 454 to 450 bytes; while files of that size
are not generated in any GitLab CI job, they are in other environments
where the test passes.
The fstrm_capture utility is started in the background during the
"dnstap" system test. Consequently, "rndc dnstap-reopen" and similar
commands may be executed before fstrm_capture starts listening on the
Unix domain socket it is configured to receive dnstap data on. This
results in the dnstap data sent to that socket in the meantime to be
lost; while the fstrm writer thread is able to recover from such a
scenario within a couple of seconds (by reopening the configured dnstap
destination itself), only one write attempt is made for data
successfully queued to the writer thread, so dnstap frames can still be
lost in the process. This may happen during the "dnstap" system test,
leading to the dnstap output file being empty, which in turn causes the
test to fail.
Fix by waiting until fstrm_capture starts listening on the Unix domain
socket it is configured to use before asking named to reopen the
configured dnstap destination. Since various fstrm_capture versions log
different messages when the listening socket is set up, wait for a
common string that works for all fstrm_capture versions released to
date. Add a few extra debug messages indicating test progress and make
the test fail if the expected fstrm_capture log message is not generated
within 10 seconds.
The fstrm_capture.out file is overwritten when the fstrm_capture utility
is restarted during the "dnstap" system test. Use a separate output
file for each fstrm_capture instance to ensure all output produced by
that tool during the "dnstap" system test is preserved for forensic
purposes.
Errors getting transfer statistics from named.run where not detected
as ret was not set to one if there hadn't been a success after looping
for a while.
Commit dc6dafdad1 allows larger TTL values
in zones that go insecure, and ignores the maximum zone TTL.
This means that if you use TTL values larger than 1 day in your zone,
your zone runs the risk of going bogus before it moves safely to
insecure.
Most resolvers by default cap the maximum TTL that they cache RRsets,
at one day (Unbound, Knot, PowerDNS) so that is fine. However, BIND 9's
default is one week.
Change the default TTLsig to one week, so that also for BIND 9
resolvers in the default cases responses for zones that are going
insecure will not be evaluated as bogus.
This change does mean that when unsigning your zone, it will take six
days longer to safely go insecure, regardless of what TTL values you
use in the zone.
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.
'HOME=value command' should only change HOME for command but on
some platforms this occasionally sets HOME for the rest of the
test. Explicitly isolate the enviroment change using a sub shell.
Allow larger TTL values in zones that go insecure. This is necessary
because otherwise the zone will not be loaded due to the max-zone-ttl
of P1D that is part of the current insecure policy.
In the keymgr.c code, default back to P1D if the max-zone-ttl is set
to zero.
