Add two test zones that will be reconfigured to go insecure, by
setting the 'dnssec-policy' option to 'none'.
One zone was using inline-signing (implicitly through dnssec-policy),
the other is a dynamic zone.
Two tweaks to the kasp system test are required: we need to set
when to except the CDS/CDS Delete Records, and we need to know
when we are dealing with a dynamic zone (because the logs to look for
are slightly different, inline-signing prints "(signed)" after the
zone name, dynamic zones do not).
Some setup scripts uses DEFAULT_ALGORITHM in their dnssec-policy
and/or initial signing. The tests still used the literal values
13, ECDSAP256SHA256, and 256. Replace those occurrences where
appropriate.
The double equal sign ('==') is a Bash-specific string comparison
operator. Ensure the single equal sign ('=') is used in all POSIX shell
scripts in the system test suite in order to retain their portability.
While working on 'rndc dnssec -rollover' I noticed the following
(small) issues:
- The key files where updated with hints set to "-when" and that
should always be "now.
- The kasp system test did not properly update the test number when
calling 'rndc dnssec -checkds' (and ensuring that works).
- There was a missing ']' in the rndc.c help output.
This command is similar in arguments as -checkds so refactor the
'named_server_dnssec' function accordingly. The only difference
are that:
- It does not take a "publish" or "withdrawn" argument.
- It requires the key id to be set (add a check to make sure).
Add tests that will trigger rollover immediately and one that
schedules a test in the future.
Sometimes, not all keys have been created in time before 'check_keys'
is called. Run a 'retry_quiet' on checking the number of keys before
continuing checking the key data.
Use the testcrypto script to see if these algorithms are supported by
openssl. If so, add the specific configuration to the named.conf file
and touch a file to indicate support. If the file exists, the
corresponding setup and tests are performed.
The CDS/CDNSKEY record will be published when the DS is in the
rumoured state. However, with the introduction of the rndc '-checkds'
command, the logic in the keymgr was changed to prevent the DS
state to go in RUMOURED unless the specific command was given. Hence,
the CDS was never published before it was seen in the parent.
Initially I thought this was a policy approval rule, however it is
actually a DNSSEC timing rule. Remove the restriction from
'keymgr_policy_approval' and update the 'keymgr_transition_time'
function. When looking to move the DS state to OMNIPRESENT it will
no longer calculate the state from its last change, but from when
the DS was seen in the parent, "DS Publish". If the time was not set,
default to next key event of an hour.
Similarly for moving the DS state to HIDDEN, the time to wait will
be derived from the "DS Delete" time, not from when the DS state
last changed.
The 'rndc_checkds' utility now allows "now" as the time when the DS
has been seen in/seen removed from the parent.
Also it uses "KEYX" as the key argument, rather than key id.
The 'rndc_checkds' will retrieve the key from the "KEYX" string. This
makes the call a bit more readable.
This commit has a lot of updates on comments, mainly to make the
system test more readable.
Also remove some redundant signing policy checks (check_keys,
check_dnssecstatus, check_keytimes).
Finally, move key time checks and expected key time settings above
'rndc_checkds' calls (with the new way of testing next key event
times there is no need to do them after 'rndc_checkds', and moving
them above 'rndc_checkds' makes the flow of testing easier to follow.
Prevent intermittent false positives on slow platforms by subtracting
the number of seconds which passed between key creation and invoking
'rndc dnssec -checkds'.
This particularly fails for the step3.csk-roll2.autosign zone because
the closest next key event is when the zone signatures become
omnipresent. Running 'rndc dnssec -checkds' some time later means
that the next key event is in fact closer than the calculated time
and thus we need to adjust the expected time by the time already
passed.
Make sure the 'checkds' command correctly sets the right key timing
metadata and also make sure that it rejects setting the key timing
metadata if there are multiple keys with the KSK role and no key
identifier is provided.
With 'checkds' replacing 'parent-registration-delay', the kasp
test needs the expected times to be adjusted. Also the system test
needs to call 'rndc dnssec -checkds' to progress the rollovers.
Since we pretend that the KSK is active as soon as the DS is
submitted (and parent registration delay is no longer applicable)
we can simplify the 'csk_rollover_predecessor_keytimes' function
to take only one "addtime" parameter.
This commit also slightly changes the 'check_dnssecstatus' function,
passing the zone as a parameter.
The $SYSTEMTESTTOP shell variable if often set to .. in various shell
scripts inside bin/tests/system/, but most of the time it is only
used one line later, while sourcing conf.sh. This hardly improves
code readability.
$SYSTEMTESTTOP is also used for the purpose of referencing
scripts/files living in bin/tests/system/, but given that the
variable is always set to a short, relative path, we can drop it and
replace all of its occurrences with the relative path without adversely
affecting code readability.
While the creation and publication times of the various keys
in this policy are nearly at the same time there is a chance that
one key is created a second later than the other.
The `set_keytimes_algorithm_policy` mistakenly set the keytimes
for KEY3 based of the "published" time from KEY2.
this changes most visble uses of master/slave terminology in tests.sh
and most uses of 'type master' or 'type slave' in named.conf files.
files in the checkconf test were not updated in order to confirm that
the old syntax still works. rpzrecurse was also left mostly unchanged
to avoid interference with DNSRPS.
as "type primary" is preferred over "type master" now, it makes
sense to make "primaries" available as a synonym too.
added a correctness check to ensure "primaries" and "masters"
cannot both be used in the same zone.
Implement the 'rndc dnssec -status' command that will output
some information about the key states, such as which policy is
used for the zone, what keys are in use, and when rollover is
scheduled.
Add loose testing in the kasp system test, the actual times are
already tested via key file inspection.
The wait until zones are signed after rndc reconfig is broken
because the zones are already signed before the reconfig. Fix
by having a different way to ensure the signing of the zone is
complete. This does require a call to the "wait_for_done_signing"
function after each "check_keys" call after the ns6 reconfig.
The "wait_for_done_signing" looks for a (newly added) debug log
message that named will output if it is done signing with a certain
key.
The logic in `keymgr_key_has_successor(key, keyring)` is flawed, it
returns true if there is any key in the keyring that has a successor,
while what we really want here is to make sure that the given key
has a successor in the given keyring.
Rather than relying on `keymgr_key_exists_with_state`, walk the
list of keys in the keyring and check if the key is a successor of
the given predecessor key.
This improves keytime testing on CSK rollover. It now
tests for specific times, and also tests for SyncPublish and
Removed keytimes.
Since an "active key" for ZSK and KSK means something
different, this makes it tricky to decide when a CSK is
active. An "active key" intuitively means the key is signing
so we say a CSK is active when it is creating zone signatures.
This change means a lot of timings for the CSK rollover tests
need to be adjusted.
The keymgr code needs a slight change on calculating the
prepublication time: For a KSK we need to include the parent
registration delay, but for CSK we look at the zone signing
property and stick with the ZSK prepublication calculation.
Registration delay is not part of the Iret retire interval, thus
removed from the calculation when setting the Delete time metadata.
Include the registration delay in prepublication time, because
we need to prepublish the key sooner than just the Ipub
publication interval.
This commit adds testing keytiming metadata. In order to facilitate
this, the kasp system test undergoes a few changes:
1. When finding a key file, rather than only saving the key ID,
also save the base filename and creation date with `key_save`.
These can be used later to set expected key times.
2. Add a test function `set_addkeytime` that takes a key, which
keytiming to update, a datetime in keytiming format, and a number
(seconds) to add, and sets the new time in the given keytime
parameter of the given key. This is used to set the expected key
times.
3. Split `check_keys` in `check_keys` and `check_keytimes`. First we
need to find the keyfile before we can check the keytimes.
We need to retrieve the creation date (and sometimes other
keytimes) to determine the other expected key times.
4. Add helper functions to set the expected key times per policy.
This avoids lots of duplication.
Check for keytimes for the first test cases (all that do not cover
rollovers).
After removing dnssec-settime calls that set key rollover
relationship, we can adjust the counts in test output filenames.
Also fix a couple of more wrong counts in output filenames.
Using dnssec-setttime after dnssec-keygen in the kasp system test
can lead to off by one second failures, so reduce the usage of
dnssec-settime in the setup scripts. This commit deals with
setting the key rollover relationship (predecessor/successor).
In the kasp system test, we are going to set the keytimes on
dnssec-keygen so we can test them against the key creation time.
This prevents off by one second in the test, something that can
happen if you set those times with dnssec-settime after
dnssec-keygen.
Also fix some test output filenames.
For testing purposes mainly, we want to allow set keytimings on
generated keys, such that we don't have to "keygen/settime" which
can result in one second off times.
The rewrite of BIND 9 build system is a large work and cannot be reasonable
split into separate merge requests. Addition of the automake has a positive
effect on the readability and maintainability of the build system as it is more
declarative, it allows conditional and we are able to drop all of the custom
make code that BIND 9 developed over the years to overcome the deficiencies of
autoconf + custom Makefile.in files.
This squashed commit contains following changes:
- conversion (or rather fresh rewrite) of all Makefile.in files to Makefile.am
by using automake
- the libtool is now properly integrated with automake (the way we used it
was rather hackish as the only official way how to use libtool is via
automake
- the dynamic module loading was rewritten from a custom patchwork to libtool's
libltdl (which includes the patchwork to support module loading on different
systems internally)
- conversion of the unit test executor from kyua to automake parallel driver
- conversion of the system test executor from custom make/shell to automake
parallel driver
- The GSSAPI has been refactored, the custom SPNEGO on the basis that
all major KRB5/GSSAPI (mit-krb5, heimdal and Windows) implementations
support SPNEGO mechanism.
- The various defunct tests from bin/tests have been removed:
bin/tests/optional and bin/tests/pkcs11
- The text files generated from the MD files have been removed, the
MarkDown has been designed to be readable by both humans and computers
- The xsl header is now generated by a simple sed command instead of
perl helper
- The <irs/platform.h> header has been removed
- cleanups of configure.ac script to make it more simpler, addition of multiple
macros (there's still work to be done though)
- the tarball can now be prepared with `make dist`
- the system tests are partially able to run in oot build
Here's a list of unfinished work that needs to be completed in subsequent merge
requests:
- `make distcheck` doesn't yet work (because of system tests oot run is not yet
finished)
- documentation is not yet built, there's a different merge request with docbook
to sphinx-build rst conversion that needs to be rebased and adapted on top of
the automake
- msvc build is non functional yet and we need to decide whether we will just
cross-compile bind9 using mingw-w64 or fix the msvc build
- contributed dlz modules are not included neither in the autoconf nor automake
Add two tests that checks that dynamic zones
can be updated and will be signed appropriately.
One zone covers an update with freeze/thaw, the
other covers an update through nsupdate.
