The 'nsupdate' tool, when sending SOA queries, uses a hard-coded value
3 UDP retries and of 5 seconds of timeout for UDP queries, and 100
seconds of timeout for TCP queries.
Use the timeout and retry values which can be configured using the
-t, -u, -r command line options, and which are already used for
sending the update query.
The manual page of nsupdate's '-u udptimeout' option states that, quote:
> If zero, the interval is computed from the timeout interval and number
> of UDP retries.
However, nsupdate sets the UDP timeout value to UINT_MAX when it is 0,
thus, not behaving as documented.
Let dns_request_create() calculate the UDP timeout, if it was set to 0.
* nsupdate should take 12 seconds (one try and three retries with
3 second timeout for each), UDP mode
* nsupdate -u 4 -r 1 should take 8 seconds (one try and one retry with
4 second timeout for each), UDP mode
* nsupdate -u 0 -t 8 -r 1 should also take 8 seconds, UDP mode
* nsupdate -u 4 -t 30 -r 1 should also take 8 seconds, as -u takes
precedence over -t, UDP mode
* nsupdate -t 8 -v should also take 8 seconds, TCP mode
The checkds system test could fail if some parent secondary servers did
not yet loaded all the zones before ns9 started sending DS queries. This
leads to SERVFAIL responses, while the test case expects good DS
responses. In order to mitigate against this issue, call 'rndc loadkeys'
to quickly restart the checkds procedure again.
Also refactor the checkds system test, to get rid of the many zone
name duplications. Update the functions 'zone_check' and
'keystate_check' to make the zone name an FQDN so we can just pass
the 'zone' variable into the function.
If the 'checkds' option is not explicitly set, check if there are
'parental-agents' for the zone configured. If so, default to "explicit",
otherwise default to "yes".
Add two new checkds test servers, that are hidden secondaries (hidden
as in not published in the NS RRset), that can be used specifically
for testing explicitly configured parental-agents.
Implement the new feature, automatic parental-agents. This is enabled
with 'checkds yes'.
When set to 'yes', instead of querying the explicit configured
parental agents, look up the parental agents by resolving the parent
NS records. The found parent NS RRset is considered to be the list
of parental agents that should be queried during a KSK rollover,
looking up the DS RRset corresponding to the key signing keys.
For each NS record, look up the addresses in the ADB. These addresses
will be used to send the DS requests. Count the number of servers and
keep track of how many good DS responses were seen.
The previous test cases already test the more complex case where there
are empty non-terminals between the child apex and the parent domain.
Add a test case where this is not the case, to execute the other code
path.
Add test cases for when checkds is disabled. Copy the test cases that
would have resulted in a DSPublish or DSRemoved and make sure that
with 'checkds no' the metadata is not set.
Add the test cases for automatic parental-agents, i.e. when 'checkds'
is set to 'yes'. Split out the special cases that use a reference
or a resolver as parental-agent so that the common use cases can be
tested with the same function.
Make the checkds system test more structured with the many more test
cases to come. Add a README for clarity.
Update the 'has_signed_apex_nsec' helper function so it can take any
domain name regardless of the number of labels.
Change the DNS tree structure such that we have different TLD names
for the various test scenarios, because we need servers that respond
differently to DS queries. Note that this isn't applicable to the
existing "checkds explicit" test cases, but is preparation work for
testing "checkds yes" (automatic parental agents).
Add a trust-anchor to the server that will be querying for parent
NS records.
Add a new configuration option to set how the checkds method should
work. Acceptable values are 'yes', 'no', and 'explicit'.
When set to 'yes', the checkds method is to lookup the parental agents
by querying the NS records of the parent zone.
When set to 'no', no checkds method is enabled. Users should run
the 'rndc checkds' command to signal that DS records are published and
withdrawn.
When set to 'explicit', the parental agents are explicitly configured
with the 'parental-agents' configuration option.
This should have no functional effects.
The message size stats are specified by RSSAC002 so it's best not
to mess around with how they appear in the statschannel. But it's
worth changing the implementation to use general-purpose histograms,
to reduce code size and benefit from sharded counters.
Cleanup the remnants of MS Compiler bits from <isc/refcount.h>, printing
the information in named/main.c, and cleanup some comments about Windows
that no longer apply.
The bits in picohttpparser.{h,c} were left out, because it's not our
code.
When fatal is called we may be holding memory allocated by OpenSSL.
This may result in the reference count for the FIPS provider not
going to zero and the shared library not being unloaded during
OPENSSL_cleanup. When the shared library is ultimately unloaded,
when all remaining dynamically loaded libraries are freed, we have
already destroyed the memory context we where using to track memory
leaks / late frees resulting in INSIST being called.
Disable triggering the INSIST when fatal has being called.
hypothesis prior to 4.41.2 uses hashlib.md5 which is not FIPS
compliant causing the wildcard system test to fail. Check if
we are running if FIPS mode and if so make the minimum version
of hypothesis we will accept to be 4.41.2.
The existing set of kerberos credential used deprecated algorithms
which are not supported by some implementations in FIPS mode.
Regenerate the saved credentials using more modern algorithms.
Added tsiggss/krb/setup.sh which sets up a test KDC with the required
principals for the system test to work. The tsiggss system test
needs to be run once with this active and KRB5_CONFIG appropriately.
set. See tsiggss/tests.sh for an example of how to do this.
OPENSSL_CONF="" is treated differently to no OPENSSL_CONF in
the environment by OpenSSL. OPENSSL_CONF="" lead to crypto
failure being reported in FIPS mode.
There are times where you want named-checkconf to check whether the
dnssec-policies should be constrained by the cryptographic algorithms
supported by the operation system or to just accept all possible
algorithms. This provides a mechanism to make that selection.
