On Windows, the iocompletionport_createthreads() didn't use
isc_thread_create() to create new threads for processing IO, but just a
simple CreateThread() function that completely circumvent the
isc_trampoline mechanism to initialize global isc_tid_v. This lead to
segmentation fault in isc_hp API because '-1' isn't valid index to the
hazard pointer array.
This commit changes the iocompletionport_createthreads() to use
isc_thread_create() instead of CreateThread() to properly initialize
isc_tid_v.
The nsupdate system test did not record failures from the
'update_test.pl' Perl script. This was because the 'ret' value was
not being saved outside the '{ $PERL ... || ret=1 } cat_i' scope.
Change this piece to store the output in a separate file and then
cat its contents. Now the 'ret' value is being saved.
Also record failures in 'update_test.pl' if sending the update
failed.
Add missing 'n' incrementals to 'nsupdate/test.sh' to keep track of
test numbers.
By default readthedocs.org uses Sphinx 1.8.5, but MR !4563 has
introduced depedency on ReferenceRole class which is available only in
Sphinx 2.0.0.
Path to doc/arm/requirements.txt needs to be configured in
readthedocs.org.
Add a test case when a dnssec-policy is reconfigured to "none",
without setting it to "insecure" first. This is unsupported behavior,
but we want to make sure the behavior is somewhat expected. The
zone should remain signed (but will go bogus once the signatures
expire).
Update the ARM to mention the new built-in "insecure" policy. Update
the DNSSEC guide recipe "Revert to unsigned" to add the additional
step of reconfiguring the zone to "insecure" (instead of immediately
set it to "none").
While it is meant to be used for transitioning a zone to insecure,
add a test case where a zone uses the "insecure" policy immediately.
The zone will go through DNSSEC maintenance, but the outcome should
be the same as 'dnssec-policy none;', that is the zone should be
unsigned.
The tests for going insecure should be changed to use the built-in
"insecure" policy.
The function that checks dnssec status output should again check
for the special case "none".
Add a new built-in policy "insecure", to be used to gracefully unsign
a zone. Previously you could just remove the 'dnssec-policy'
configuration from your zone statement, or remove it.
The built-in policy "none" (or not configured) now actually means
no DNSSEC maintenance for the corresponding zone. So if you
immediately reconfigure your zone from whatever policy to "none",
your zone will temporarily be seen as bogus by validating resolvers.
This means we can remove the functions 'dns_zone_use_kasp()' and
'dns_zone_secure_to_insecure()' again. We also no longer have to
check for the existence of key state files to figure out if a zone
is transitioning to insecure.
* The location of the digest type field has changed to where the
reserved field was.
* The reserved field is now called scheme and is where the digest
type field was.
* Digest type 2 has been defined (SHA256).
dnstap_test produces TSAN errors which originate in libfstrm.so. Unless
libfstrm is TSAN clean or a workaround is placed in libfstrm sources,
suppressing TSAN coming from libfstrm is necessary to test DNSTAP under
TSAN.
All platforms but OpenBSD have dnstap dependencies readily in their
respective repositories, and dnstap thus can be tested there. Given that
majority of images have dnstap dependencies available, it seems fitting
to make dnstap enabled by default.
The pytest "cacheprovider" plugin produces a .cache/v/cache/lastfailed
file, which holds a Python dictionary structure with failed tests.
However, on Ubuntu 16.04 (Xenial) the file is created even though the
test passed and the file contains just an empty dictionary ("{}").
Given that we are not interested in this feature, disabling the
"cacheprovider" plugin globally and removing per-test removals of the
.cache directory seems like the best course of action.
Define a :gl: Sphinx role that takes a GitLab issue/MR number as an
argument and creates a hyperlink to the relevant ISC GitLab URL. This
makes it easy to reach ISC GitLab pages directly from the release notes.
Make all GitLab references in the release notes use the new Sphinx role.
When the `named` would hang on startup it would be killed with SIGKILL
leaving us with no information about the state the process was in.
This commit changes the start.pl script to send SIGABRT instead, so we
can properly collect and process the coredump from the hung named
process.
When reducing the number of NSEC3 iterations to 150, commit
aa26cde2ae added tests for dnssec-policy
to check that a too high iteration count is a configuration failure.
The test is not sufficient because 151 was always too high for
ECDSAP256SHA256. The test should check for a different algorithm.
There was an existing test case that checks for NSEC3 iterations.
Update the test with the new maximum values.
Update the code in 'kaspconf.c' to allow at most 150 iterations.
