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.

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.

While working on the serve-stale backports, I noticed the following
oddities:
1. In the serve-stale system test, in one case we keep track of the
time how long it took for dig to complete. In commit
aaed7f9d8c, the code removed the
exception to check for result == ISC_R_SUCCESS on stale found
answers, and adjusted the test accordingly. This failed to update
the time tracking accordingly. Move the t1/t2 time track variables
back around the two dig commands to ensure the lookups resolved
faster than the resolver-query-timeout.
2. We can remove the setting of NS_QUERYATTR_STALEOK and
DNS_RDATASETATTR_STALE_ADDED on the "else if (stale_timeout)"
code path, because they are added later when we know we have
actually found a stale answer on a stale timeout lookup.
3. We should clear the NS_QUERYATTR_STALEOK flag from the client
query attributes instead of DNS_RDATASETATTR_STALE_ADDED (that
flag is set on the rdataset attributes).
4. In 'bin/named/config.c' we should set the configuration options
in alpabetical order.
5. In the ARM, in the backports we have added "(stale)" between
"cached" and "RRset" to make more clear a stale RRset may be
returned in this scenario.

Exerting excessive I/O load on the host running system tests should be
avoided in order to limit the number of false positives reported by the
system test suite. In some cases, running named with "-d 99" (which is
the default for system tests) results in a massive amount of logs being
generated, most of which are useless. Implement a log file size check
to draw developers' attention to overly verbose named instances used in
system tests. The warning threshold of 200,000 lines was chosen
arbitrarily.
(cherry picked from commit 241e85ef0c)
The regression test for CVE-2020-8620 causes a lot of useless messages
to be logged. However, globally decreasing the log level for the
affected named instance would be a step too far as debugging information
may be useful for troubleshooting other checks in the "tcp" system test.
Starting a separate named instance for a single check should be avoided
when possible and thus is also not a good solution. As a compromise,
run "rndc trace 1" for the affected named instance before starting the
regression test for CVE-2020-8620.
(cherry picked from commit 17e5c2a50e)
The system test framework starts all named instances with the "-d 99"
command line option (unless it is overridden by a named.args file in a
given instance's working directory). This causes a lot of log messages
to be written to named.run files - currently over 5 million lines for a
single test suite run. While debugging information preserved in the log
files is essential for troubleshooting intermittent test failures, some
system tests involve sending hundreds or even thousands of queries,
which causes the relevant log files to explode in size. When multiple
tests (or even multiple test suites) are run in parallel, excessive
logging contributes considerably to the I/O load on the test host,
increasing the odds of intermittent test failures getting triggered.
Decrease the debug level for the seven most verbose named instances:
- use "-d 3" for ns2 in the "cacheclean" system test (it is the lowest
logging level at which the test still passes without the need to
apply any changes to tests.sh),
- use "-d 1" for the other six named instances.
This roughly halves the number of lines logged by each test suite run
while still leaving enough information in the logs to allow at least
basic troubleshooting in case of test failures.
This approach was chosen as it results in a greater decrease in the
number of lines logged than running all named instances with "-d 3",
without causing any test failures.

The test spawns 4 parallel workers that keep adding, modifying and

While environment and timing issues may affect the test, in most

If "tkey-gssapi-credential" is set in the configuration and GSSAPI

named.conf if GSSAPI support is available.

If we don't wait for named to finish starting, 'rndc stop' may
fail due to the listen limit being reached in named leading
to a false negative test
(cherry picked from commit 8d5870f9df)
Four named instances in the "nsupdate" system test have GSS-TSIG support
enabled. All of them currently use "tkey-gssapi-keytab". Configure two
of them with "tkey-gssapi-credential" to test that option.
As "tkey-gssapi-keytab" and "tkey-gssapi-credential" both provide the
same functionality, no test modifications are required. The difference
between the two options is that the value of "tkey-gssapi-keytab" is an
explicit path to the keytab file to acquire credentials from, while the
value of "tkey-gssapi-credential" is the name of the principal whose
credentials should be used; those credentials are looked up in the
keytab file expected by the Kerberos library, i.e. /etc/krb5.keytab by
default. The path to the default keytab file can be overridden using by
setting the KRB5_KTNAME environment variable. Utilize that variable to
use existing keytab files with the "tkey-gssapi-credential" option.
The KRB5_KTNAME environment variable should not interfere with the
"tkey-gssapi-keytab" option. Nevertheless, rename one of the keytab
files used with "tkey-gssapi-keytab" to something else than the contents
of the KRB5_KTNAME environment variable in order to make sure that both
"tkey-gssapi-keytab" and "tkey-gssapi-credential" are actually tested.

Previously, the taskmgr, timermgr and socketmgr had a constructor
variant, that would create the mgr on top of existing appctx. This was
no longer true and isc_<*>mgr was just calling isc_<*>mgr_create()

This commit just cleans up the extra function.

Too much logic was cramped inside the dns_journal_rollforward() that
made it harder to follow. The dns_journal_rollforward() was refactored
to work over already opened journal and some of the previous logic was
moved to new static zone_journal_rollforward() that separates the
journal "rollforward" logic from the "zone" logic.
(cherry picked from commit 55b942b4a0)
when dns_journal_rollforward returned ISC_R_RECOVERABLE the distintion
between 'up to date' and 'success' was lost, as a consequence
zone_needdump() was called writing out the zone file when it shouldn't
have been. This change restores that distintion. Adjust system
test to reflect visible changes.

Due to the lack of "match-clients" clauses in ns4/named2.conf.in, the
same view is incorrectly chosen for all queries received by ns4 in the
"keymgr2kasp" system test. This causes only one version of the
"view-rsasha256.kasp" zone to actually be checked. Add "match-clients"
clauses to ns4/named2.conf.in to ensure the test really checks what it
claims to.
Use identical view names ("ext", "int") in ns4/named.conf.in and
ns4/named2.conf.in so that it is easier to quickly identify the
differences between these two files.
Update tests.sh to account for the above changes. Also fix a copy-paste
error in a comment to prevent confusion.
(cherry picked from commit 0de5a576c5)
The test case for a zone with a missing include file was wrong for two
reasons:
1. It was loading the wrong file (master5 instead of master6)
2. It did actually not set the $ret variable to 1 if the test failed
(it should default to ret=1 and clear the variable if the
appropriate log is found).
(cherry picked from commit 96583e7c40)
Add a test case for inline-signing for a zone with an $INCLUDE
statement. There is already a test for a missing include file, this
one adds a test for a zone with an include file that does exist.
Test if the record in the included file is loaded.
(cherry picked from commit 6463ee0f40)
The draft says that the NSEC(3) TTL must have the same TTL value
as the minimum of the SOA MINIMUM field and the SOA TTL. This was
always the intended behaviour.
Update the zone structure to also track the SOA TTL. Whenever we
use the MINIMUM value to determine the NSEC(3) TTL, use the minimum
of MINIMUM and SOA TTL instead.
There is no specific test for this, however two tests need adjusting
because otherwise they failed: They were testing for NSEC3 records
including the TTL. Update these checks to use 600 (the SOA TTL),
rather than 3600 (the SOA MINIMUM).
(cherry picked from commit 9af8caa733)
It is more intuitive to have the countdown 'max-stale-ttl' as the
RRset TTL, instead of 0 TTL. This information was already available
in a comment "; stale (will be retained for x more seconds", but
Support suggested to put it in the TTL field instead.
(cherry picked from commit a83c8cb0af)
Before binding an RRset, check the time and see if this record is
stale (or perhaps even ancient). Marking a header stale or ancient
happens only when looking up an RRset in cache, but binding an RRset
can also happen on other occasions (for example when dumping the
database).
Check the time and compare it to the header. If according to the
time the entry is stale, but not ancient, set the STALE attribute.
If according to the time is ancient, set the ANCIENT attribute.
We could mark the header stale or ancient here, but that requires
locking, so that's why we only compare the current time against
the rdh_ttl.
Adjust the test to check the dump-db before querying for data. In the
dumped file the entry should be marked as stale, despite no cache
lookup happened since the initial query.
(cherry picked from commit debee6157b)
When introducing change 5149, "rndc dumpdb" started to print a line
above a stale RRset, indicating how long the data will be retained.
At that time, I thought it should also be possible to load
a cache from file. But if a TTL has a value of 0 (because it is stale),
stale entries wouldn't be loaded from file. So, I added the
'max-stale-ttl' to TTL values, and adjusted the $DATE accordingly.
Since we actually don't have a "load cache from file" feature, this
is premature and is causing confusion at operators. This commit
changes the 'max-stale-ttl' adjustments.
A check in the serve-stale system test is added for a non-stale
RRset (longttl.example) to make sure the TTL in cache is sensible.
Also, the comment above stale RRsets could have nonsensical
values. A possible reason why this may happen is when the RRset was
marked a stale but the 'max-stale-ttl' has passed (and is actually an
RRset awaiting cleanup). This would lead to the "will be retained"
value to be negative (but since it is stored in an uint32_t, you would
get a nonsensical value (e.g. 4294362497).
To mitigate against this, we now also check if the header is not
ancient. In addition we check if the stale_ttl would be negative, and
if so we set it to 0. Most likely this will not happen because the
header would already have been marked ancient, but there is a possible
race condition where the 'rdh_ttl + serve_stale_ttl' has passed,
but the header has not been checked for staleness.

When a core file was generated after named crashed during a system test

The fromhex.pl script needs to be copied from the source directory to

Using "stale-answer-client-timeout" turns out to have unforeseen
negative consequences, and thus it is better to disable the feature
by default for the time being.
(cherry picked from commit e443279bbf)
When implementing "stale-answer-client-timeout", we decided that
we should only return positive answers prematurely to clients. A
negative response is not useful, and in that case it is better to
wait for the recursion to complete.
To do so, we check the result and if it is not ISC_R_SUCCESS, we
decide that it is not good enough. However, there are more return
codes that could lead to a positive answer (e.g. CNAME chains).
This commit removes the exception and now uses the same logic that
other stale lookups use to determine if we found a useful stale
answer (stale_found == true).
This means we can simplify two test cases in the serve-stale system
test: nodata.example is no longer treated differently than data.example.

When the authsock.pl script would be terminated with a signal,
it would leave the pidfile around. This commit adds a signal
handler that cleanups the pidfile on signals that are expected.
Added tests to ensure that dig won't retry sending a query over tcp
(+tcp) when a TCP connection is closed prematurely (EOF is read) if
either +tries=1 or retry=0 is specified on the command line.
Now that premature EOF on tcp connections take +tries and +retry into
account, the dig system tests handling TCP EOF with +tries=1 were
expecting dig to do a second attempt in handling the tcp query, which
doesn't happen anymore.
To make the test work as expected +tries value was adjusted to 2, to
make it behave as before after the new update on dig.
When calling "rndc dnssec -checkds", it may take some milliseconds
before the appropriate changes have been written to the state file.
Add retry_quiet mechanisms to allow the write operation to finish.
Also retry_quiet the check for the next key event. A "rndc dnssec"
command may trigger a zone_rekey event and this will write out
a new "next key event" log line, but it may take a bit longer than
than expected in the tests.
(cherry picked from commit 82d667e1d5)
Call 'dns_zone_rekey' after a 'rndc dnssec -checkds' or 'rndc dnssec
-rollover' command is received, because such a command may influence
the next key event. Updating the keys immediately avoids unnecessary
rollover delays.
The kasp system test no longer needs to call 'rndc loadkeys' after
a 'rndc dnssec -checkds' or 'rndc dnssec -rollover' command.

CDS/CDNSKEY DELETE records are only useful if they are signed,
otherwise the parent cannot verify these RRsets anyway. So once the DS
has been removed (and signaled to BIND), we can remove the DNSKEY and
RRSIG records, and at this point we can also remove the CDS/CDNSKEY
records.
(cherry picked from commit 6f31f62d69)
While not useful, having a CDS/CDNSKEY DELETE record in an unsigned
zone is not an error and "named-checkzone" should not complain.

Change the 'check_keys' function to try three times. Some intermittent
kasp test failures are because we are inspecting the key files
before the actual change has happen. The 'retry_quiet' approach allows
for a bit more time to let the write operation finish.
(cherry picked from commit d5531df79a)
Add two test zones that migrate to dnssec-policy. Test if the key
states are set accordingly given the timing metadata.
The rumoured.kasp zone has its Publish/Active/SyncPublish times set
not too long ago so the key states should be set to RUMOURED. The
omnipresent.kasp zone has its Publish/Active/SyncPublish times set
long enough to set the key states to OMNIPRESENT.
Slightly change the init_migration_keys function to set the
key lifetime to "none" (legacy keys don't have lifetime). Then in the
test case set the expected key lifetime explicitly.
