Move the 'zsk-prepub' zones to the rollover test dir and convert ZSK
rollover test to pytest.
We need a way to signal a smooth rollover is going on. Signatures are
being replaced gradually during a ZSK rollover, so the existing
signatures of the predecessor ZSK are still being used. Add a smooth
operator to set the right expectations on what signatures are being
used.
Setting expected key relationships is a bit crude: a list of two
elements where the first element is the index of the expected keys that
is the predecessor, and the second element is the index of the expected
keys that is the successor.
We are changing the KSK lifetime to unlimited in this test case as it
is of no importance.
Move the 'enable-dnssec' to the rollover test dir and convert to pytest.
This requires new test functionality to check that "CDS is published"
messages are logged (or prohibited).
The setup part is slightly adapted such that it no longer needs to
set the '-P sync' value in most cases (this is then set by 'named'),
and to adjust for the inappropriate safety intervals fix.
Move the multi-signer test scenarios to the rollover directory and
convert tests to pytest.
- If the KeyProperties set the "legacy" to True, don't set expected
key times, nor check them. Also, when a matching key is found, set
key.external to True.
- External keys don't show up in the 'rndc dnssec -status' output so
skip them in the 'check_dnssecstatus' function. External keys never
sign RRsets, so also skip those keys in the '_check_signatures'
function.
- Key properties strings now can set expected key tag ranges, and if
KeyProperties have tag ranges set, they are checked.
In order to keep the kasp system test somewhat approachable, let's
move all rollover scenarios to its own test directory. Starting with
the manual rollover test cases.
A new test function is added to 'isctest.kasp', to verify that the
relationship metadata (Predecessor, Successor) is set correctly.
The configuration and setup for the zone 'manual-rollover.kasp' are
almost copied verbatim, the only exception is the keytimes. Similar
to the test kasp cases, we no longer set "SyncPublish/PublishCDS" in
the setup script. In addition to that, the offset is changed from one
day ago to one week ago, so that the key states match the timing
metadata (one day is too short to move a key from "hidden" to
"omnipresent").
