The mkeys system test started to fail after introducing support for
zones transitioning to unsigned without going bogus. This is because
there was actually a bug in the code: if you reconfigure a zone and
remove the "auto-dnssec" option, the zone is actually still DNSSEC
maintained. This is because in zoneconf.c there is no call
to 'dns_zone_setkeyopt()' if the configuration option is not used
(cfg_map_get(zoptions, "auto-dnssec", &obj) will return an error).
The mkeys system test implicitly relied on this bug: initially the
root zone is being DNSSEC maintained, then at some point it needs to
reset the root zone in order to prepare for some tests with bad
signatures. Because it needs to inject a bad signature, 'auto-dnssec'
is removed from the configuration.
The test pass but for the wrong reasons:
I:mkeys:reset the root server
I:mkeys:reinitialize trust anchors
I:mkeys:check positive validation (18)
The 'check positive validation' test works because the zone is still
DNSSEC maintained: The DNSSEC records in the signed root zone file on
disk are being ignored.
After fixing the bug/introducing graceful transition to insecure,
the root zone is no longer DNSSEC maintained after the reconfig.
The zone now explicitly needs to be reloaded because otherwise the
'check positive validation' test works against an old version of the
zone (the one with all the revoked keys), and the test will obviously
fail.
(cherry picked from commit 2fc42b598b)
this adds functions in conf.sh.common to create DS-style trust anchor
files. those functions are then used to create nearly all of the trust
anchors in the system tests.
there are a few exceptions:
- some tests in dnssec and mkeys rely on detection of unsupported
algorithms, which only works with key-style trust anchors, so those
are used for those tests in particular.
- the mirror test had a problem with the use of a CSK without a
SEP bit, which still needs addressing
in the future, some of these tests should be changed back to using
traditional trust anchors, so that both types will be exercised going
forward.
When trying to extract the key ID from a key file name, some test code
incorrectly attempts to strip all leading zeros. This breaks tests when
keys with ID 0 are generated. Add a new helper shell function,
keyfile_to_key_id(), which properly handles keys with ID 0 and use it in
test code whenever a key ID needs to be extracted from a key file name.
- trusted-keys is now flagged as deprecated, but still works
- managed-keys can be used to configure permanent trust anchors by
using the "static-key" keyword in place of "initial-key"
- parser now uses an enum for static-key and initial-key keywords
Some values returned by dstkey_fromconfig() indicate that key loading
should be interrupted, others do not. There are also certain subsequent
checks to be made after parsing a key from configuration and the results
of these checks also affect the key loading process. All of this
complicates the key loading logic.
In order to make the relevant parts of the code easier to follow, reduce
the body of the inner for loop in load_view_keys() to a single call to a
new function, process_key(). Move dstkey_fromconfig() error handling to
process_key() as well and add comments to clearly describe the effects
of various key loading errors.
These tests check if a key with an unsupported algorithm in
managed-keys is ignored and when seeing an algorithm rollover to
an unsupported algorithm, the new key will be ignored too.
The keyfile and key ID for the original managed key do not change
throughout the mkeys system test. Keep them in helper variables to
prevent calling "cat" multiple times and improve code readability.
Reduce code duplication by replacing a code snippet repeated throughout
system tests using "trusted-keys" and/or "managed-keys" configuration
sections with calls to keyfile_to_{managed,trusted}_keys() helper
functions.
Calling nextpart() after reconfiguring ns1 is not safe, because the
expected log message may appear in ns5/named.run before nextpart() is
run. With the TTL for ./DNSKEY set to 20 seconds, ns5 will refresh it
after 10 seconds, by which time wait_for_log() will already have failed.
This results in a false negative.
However, just calling nextpart() before reconfiguring ns1 would
introduce a different problem: if ns5 refreshed ./DNSKEY between these
two steps, the subsequent wait_for_log() call would return immediately
as it would come across the log message about a failure while refreshing
./DNSKEY instead of the expected success. This in turn would result in
a different false negative as the root key would still be uninitialized
by the time "rndc secroots" is called.
Prevent both kinds of false negatives by:
- calling nextpart() before reconfiguring ns1, in order to prevent the
first case described above,
- looking for a more specific log message, in order to prevent the
second case described above.
Also look for a more specific log message in the first part of the
relevant check, not to fix any problem, but just to emphasize that a
different fetch result is expected in that case.
With these tweaks in place, if a (failed) ./DNSKEY refresh is scheduled
between nextpart() and reconfiguring ns1, wait_for_log() will just wait
for two more seconds (one "hour"), at which point another refresh
attempt will be made that will succeed.

4798. [func] Keys specified in "managed-keys" statements
are tagged as "initializing" until they have been
updated by a key refresh query. If initialization
fails it will be visible from "rndc secroots".
[RT #46267]
This reverts commit 560d8b833e.
This change created a potential race between key refresh queries and
root zone priming queries which could leave the root name servers in
the bad-server cache.
4773. [bug] Keys specified in "managed-keys" statements
can now only be used when validating key refresh
queries during initialization of RFC 5011 key
maintenance. If initialization fails, DNSSEC
validation of normal queries will also fail.
Previously, validation of normal queries could
succeed using the initializing key, potentially
masking problems with managed-keys. [RT #46077]
4750. [func] "rndc managed-keys destroy" shuts down RFC 5011 key
maintenance and deletes the managed-keys database.
If followed by "rndc reconfig" or a server restart,
key maintenance is reinitialized from scratch.
This is primarily intended for testing. [RT #32456]
4594. [func] dnssec-keygen no longer uses RSASHA1 by default;
the signing algorithm must be specified on
the command line with the "-a" option. Signing
scripts that rely on the existing default behavior
will break; use "dnssec-keygen -a RSASHA1" to
repair them. (The goal of this change is to make
it easier to find scripts using RSASHA1 so they
can be changed in the event of that algorithm
being deprecated in the future.) [RT #44755]
4642. [cleanup] Add more logging of RFC 5011 events affecting the
status of managed keys: newly observed keys,
deletion of revoked keys, etc. [RT #45354]
to provide feedback to the trust-anchor administrators
about how key rollovers are progressing as per
draft-ietf-dnsop-edns-key-tag-02. This can be
disabled using 'trust-anchor-telemetry no;'.
[RT #40583]
