the "random-device" option was made non-functional in 9.13, but was
not marked as obsolete at that time. this is now fixed; configuring
"random-device" will trigger a warning.
Reduce the number of places that know about the number of IP addresses
required by the system tests, by changing `testsock.pl` to read the
`max` from `ifconfig.sh.in`. This should make the test runner fail
early with a clear message when the interfaces have been set up by an
obsolete script.
Add comments to cross-reference `ifconfig.sh.in`, `testsock.pl`, and
`org.isc.bind.system` to make it easier to remember what needs
updating when an IP address is added.

It is possible to bypass Response Rate Limiting (RRL)
`responses-per-second` limitation using specially crafted wildcard
names, because the current implementation, when encountering a found
DNS name generated from a wildcard record, just strips the leftmost
label of the name before making a key for the bucket.
While that technique helps with limiting random requests like
<random>.example.com (because all those requests will be accounted
as belonging to a bucket constructed from "example.com" name), it does
not help with random names like subdomain.<random>.example.com.
The best solution would have been to strip not just the leftmost
label, but as many labels as necessary until reaching the suffix part
of the wildcard record from which the found name is generated, however,
we do not have that information readily available in the context of RRL
processing code.
Fix the issue by interpreting all valid wildcard domain names as
the zone's origin name concatenated to the "*" name, so they all will
be put into the same bucket.

The zone 'retransfer3.' tests whether zones that 'rndc signing
-nsec3param' requests are queued even if the zone is not loaded.
The test assumes that if 'rndc signing -list' shows that the zone is
done signing with two keys, and there are no NSEC3 chains pending, the
zone is done handling the '-nsec3param' queued requests. However, it
is possible that the 'rndc signing -list' command is received before
the corresponding privatetype records are added to the zone (the records
that are used to retrieve the signing status with 'rndc signing').
This is what happens in test failure
https://gitlab.isc.org/isc-projects/bind9/-/jobs/2722752.
The 'rndc signing -list retransfer3' is thus an unreliable check.
It is simpler to just remove the check and wait for a certain amount
of time and check whether ns3 has re-signed the zone using NSEC3.
(cherry picked from commit 8b71cbd09c)
The wait_for_zone_is_signed function was never called, which could lead
to test failures due to timing issues (where a zone was not fully signed
yet, but the test was trying to verify the zone).
Also add two missing set_nsec3param calls to ensure the ITERATIONS
value is set for these test cases.

Add two scenarios where we change the dnssec-policy from using RSASHA1
to something with NSEC3.
The first case should work, as the DS is still in hidden state and we
can basically do anything with DNSSEC.
The second case should fail, because the DS of the predecessor is
published and we can't immediately remove the predecessor DNSKEY. So
in this case we should keep the NSEC chain for a bit longer.
Add two more scenarios where we change the dnssec-policy from using
NSEC3 to something NSEC only. Both should work because there are no
restrictions on using NSEC when it comes to algorithms, but in the
cases where the DS is published we can't bluntly remove the predecessor.
Extend the nsec3 system test by also checking the DNSKEY RRset for the
expected DNSKEY records. This requires some "kasp system"-style setup
for each test (setting key properties and key states). Also move the
dnssec-verify check inside the check_nsec/check_nsec3 functions because
we will have to do that every time.

Use `nc` to check that multiple POST requests with non-empty HTTP
body are serviced normally by the statistics channel.
(cherry picked from commit bc32885ba981cab6308981936f49ab625af84bf2)
Update the "statschannel" system test to use the $((expression))
shell constucts instead of executing the `expr` program.
(cherry picked from commit 8034819b53789b52dd1c80b0256880b506a3f31b)
Before the commit some checks in the system test would try to verify
that different HTTP methods can be used and are functional. However,
until recently, it was not possible to tell from the output which
method was in fact used, so it turned out that +http-plain-get option
is broken.
This commit add the additional checks to prevent that from happening
in the future.

Stop using a RSASHA1 fixed key in ns3's named.conf as the
trusted key and instead compute a broken digest from the
real digest to use in trusted-keys.

Moves tests from being RSASHA1 based to RSASHA256 based where possible
and split out the remaining RSASHA1 based tests so that they are not
run on OS's that don't support RSASHA1.

migrate-nomatch-alglen: switched to RSASHA256 instead of RSASHA1
and the key size now changes from 2048 bits to 3072 bits instead
of 1024 bits to 2048 bits.
migrate-nomatch-algnum: switched to RSASHA256 instead of RSASHA1
as initial algorithm and adjusted mininum key size to 2048 bits.
rsasha256: adjusted minimum key size to 2048 bits.
