- Use absolute paths when invoking the convert-trs-to-junit.py script
so that it also works correctly for out-of-tree and tarball-based
test jobs.
- Quote the variables used in convert-trs-to-junit.py invocations to
future-proof the code.
- Use "&&" instead of ";" in shell pipelines invoking the
convert-trs-to-junit.py script in order to prevent "source" errors
from being silently ignored.
- Ensure convert-trs-to-junit.py is invoked from the correct directory
for out-of-tree and tarball-based unit test jobs by adding
appropriate "cd" invocations.
- Ensure the convert-trs-to-junit.py invocations are always the last
step in each 'after_script', in order to run that script from the
correct directory for out-of-tree and tarball-based system test jobs
and to ensure that any potential errors in that script do not
prevent more important steps in the 'after_script' from being
executed.
Out-of-tree build & test jobs currently defined in GitLab CI use
/tmp/out_of_tree_workspace as the working directory. This requires
juggling that directory around as it gets passed from the build job to
the test jobs and then again after the test jobs are finished, so that
artifacts can be collected for the purpose of investigating test
failures. The original intention of doing this was to ensure that
bin/tests/system/run.sh does not rely on being executed from within a
Git working copy (which happens e.g. if the out-of-tree workspace is a
subdirectory of $CI_PROJECT_DIR, i.e. the path into which GitLab
Runner clones the project in each job).
However, even with these complications in place, not all possible
scenarios that should be handled properly by the system test framework
(e.g. invoking a given test one time after another from the same
out-of-tree build directory) are tested in GitLab CI anyway. Meanwhile,
the requirement for moving the out-of-tree workspace into
$CI_PROJECT_DIR in the 'after_script' for each out-of-tree job makes
these jobs less robust than they could be; for example, if any step in
the 'after_script' returns a non-zero exit code, the job's artifacts
will not include the out-of-tree workspace, hindering troubleshooting.
Simplify job definitions in .gitlab-ci.yml by moving the workspace used
by out-of-tree build & test jobs back to a subdirectory of
$CI_PROJECT_DIR. Whether the out-of-tree workspace exists within a Git
working copy or not does not matter for Autotools, so this is considered
to be a reasonable trade-off in terms of test coverage.
With the addition of Ubuntu 22.04 three more CI jobs were added. To
compensate for that, move Ubuntu 18.04 jobs out of MR-triggered
pipelines to schedule-triggered ones.
Also, move --disable-geoip ./configure options from Ubuntu 18.04 to
Ubuntu 20.04 jobs to keep these options in the more frequent
MR-triggered pipelines.
Have system tests use required Python (dnspython) and PERL modules
(Digest::HMAC and Net::DNS) from user directories, avoid using
privileges.
Note: The pythonenv must be setup to use the same version of python as
the test uses, for example /usr/bin/python.
Thanks to Stacey Marshall.
Make clear that inline-signing stores DNSSEC records in a signed
version of the zone, using the zone's filename plus ".signed" extension.
Tell that dynamic zones store updates in the zone's filename.
DNSSEC records for dynamic zones also go in the zone's filename, unless
inline-signing is enabled.
Then, dnssec-policy assumes inline-signing, but only if the zone is
not dynamic.

If skip/xfail is used in pytest, it can have a reason string associated
with it. When evaluating these tests, it can be useful to be able to
differentiate the reason why the test was skipped/xfailed/xpassed,
because there might be multiple possible reasons for that.
The extra options passed to pytest ensure that the string with the
reason appears in the test summary and thus we're able to find the
string with the reason in the log output.

Before the changes from this commit were introduced, the accept
callback function will get called twice when accepting connection
during two of these stages:
* when accepting the TCP connection;
* when handshake has completed.
That is clearly an error, as it should have been called only once. As
far as I understand it the mistake is a result of TLS DNS transport
being essentially a fork of TCP transport, where calling the accept
callback immediately after accepting TCP connection makes sense.
This commit fixes this mistake. It did not have any very serious
consequences because in BIND the accept callback only checks an ACL
and updates stats.
Based on measurements done on BIND v9_19_2 using bank. TLD and a
synthetitc fullly signed zone, using RSASHA256 and ECDSAP256SHA256
algorithms with NSEC and NSEC3 without opt-out.
This section was completely out of date. Current measurements on dataset
Telco EU 2022-02 and BIND 9.19.1 indicate absolutely different results
than described in the old version of the text.
Guide in this repo is tied to latest version anyway, so let's not even
mention ancient versions of BIND.
This also solves the OpenSSL question because it is now mandatory for
build, which subsequently removes the entropy problem - so let's not
mention it either.
When shutting down, the interface manager can be destroyed
before the `route_connected()` callback is called, which is
unexpected for the latter and can cause a crash.
Move the interface manager attachment code from the callback
to the place before the callback is registered using
`isc_nm_routeconnect()` function, which will make sure that
the interface manager will live at least until the callback
is called.
Make sure to detach the interface manager if the
`isc_nm_routeconnect()` function is not implemented, or when
the callback is called with a result value which differs from
`ISC_R_SUCCESS`.
The `ns_interfacemgr_create()` function, when calling
`isc_nm_routeconnect()`, uses the newly created `ns_interfacemgr_t`
instance before initializing its reference count and the magic value.
Defer the `isc_nm_routeconnect()` call until the initializations
are complete.
In special NS search mode, after the initial lookup, dig starts the
followup lookup with discovered NS servers in the queries list. If one
of those queries then fail, dig, as usual, tries to start the next query
in the list, which results in a crash, because the NS search mode is
special in a way that the queries are running in parallel, so the next
query is usually already started.
Apply some special logic in `recv_done()` function to deal with the
described situation when handling the query result for the NS search
mode. Particularly, print a warning message for the failed query,
and do not try to start the next query in the list. Also, set a non-zero
exit code if all the queries in the followup lookup fail.
With the recent Coverity Scan 2021.12 version, Python 3 scripts are
being analyzed in addition to C files. The --fs-capture-search option
scripts for Coverity Scan analysis should be added to leverage this
feature.
Downloading and unpacking Coverity Scan analysis tool tarball
(cov-analysis-linux64.tgz) to $CI_PROJECT_DIR interferes with the
execution of the analysis tool when the --fs-capture-search option is
used because the tool starts to analyze some of its Javascript files.
(There's the --fs-capture-search-exclude-regex <path> option, but I
failed to find a way to make it work.)
The coverity CI job cache feature is used to ensure that the 1 GB
cov-analysis-linux64.tgz file is being cached on GitLab CI runner, where
it was downloaded in the past. This feature does not seem to work
anymore; given that the proper solution to creating distributed cache is
complicated, better to drop the feature altogether.
The only values that the isc_quota_attach() function (called from
check_recursionquota() via recursionquotatype_attach_soft()) can
currently return are: ISC_R_SUCCESS, ISC_R_SOFTQUOTA, and ISC_R_QUOTA.
Instead of just propagating any other (unexpected) error up the call
stack, assert immediately, so that if the isc_quota_* API gets updated
in the future to return values currently matching the "default"
statement, check_recursionquota() can be promptly updated to handle such
new return values as desired.
Previously, multiple code paths reused client->query.fetch, so it was
enough for ns_query_cancel() to issue a single call to
dns_resolver_cancelfetch() with that fetch as an argument. Now, since
each slot in the 'recursions' array can hold a reference to a separate
resolver fetch, ns_query_cancel() needs to handle all of them, so that
all recursion callbacks get a chance to clean up the associated
resources when a query is canceled.
