This test is outdated because it tested the 'sig-validity-interval'
option that has been replaced by dnssec-policy's 'signatures-validity',
'signatures-refresh', and 'signatures-jitter' options.
Nevertheless, it tests if the jitter is spread correctly.
Update the test to make use of 'signatures-jitter', set the value
to 1 day (meaning resign in 499 days since 'signatures-validity' is
set to 500 days).
Note that this previously changed erroneously the refresh value to
449 days (should have been 499 days, but that is not allowed by
checkconf, since it is above 90% of 'signatures-validity').
After we have changed the maximum allowed iterations to 51 for signing,
the NSEC3 chain has changed and requires one more NSEC to be returned
in the answer (plus corresponding RRSIG). So the expected number or
records in the authority section is now 8.
If the key is offline and the keymgr runs, it will treat it as a missing key,
and generate a new key (according to the policy). Fix the test by putting
back the KSK temporarily when we run 'rndc loadkeys'.
1. When generating keys, don't set timing metadata. Otherwise keys
are considered to be in use and won't be selected when dnssec-policy
starts a new key rollover.
2. Add an extra check to make sure the new ZSK (zsk2) is prepublished.
Also add a check to make sure it has become active.
3. When using dnssec-settime, add -s to also write to key state files.
The config was recently modified to ensure ns4 won't leak any queries to
root servers. However, the test wasn't executed and it turns out the way
this was handled actually broke the test case. Add our custom root hint
to both of the views to ensure the test can still pass without leaking
any queries.
An RPZ response's SOA record TTL is set to 1 instead of the SOA TTL,
a boolean value is passed on to query_addsoa, which is supposed to be
a TTL value. I don't see what value is appropriate to be used for
overriding, so we will pass UINT32_MAX.
Now that this function also creates the DNSKEY record for the KSKs,
as well as other associated records such as CDS and CDNSKEY, rename
the function to something slightly better.
Creating the KSR happens on the "ZSK side". The KSK is offline and while
the public key and state file may be present, draft-icann-dnssec-keymgmt-01.txt
suggest that the KSR only contains ZSKs.
This is also what knot dns does, so it would also be in the spirit of
interoperability.
The final line in a KSR ";; KeySigningRequest generated at ..." was
missing the version number, that has now been fixed.
Thanks Libor Peltan for reporting.
The expireheader() call in the expire_ttl_headers() function
is erroneous as it passes the 'nlocktypep' and 'tlocktypep'
arguments in a wrong order, which then causes an assertion
failure.
Fix the order of the arguments so it corresponds to the function's
prototype.
in QP keys, characters that are not common in DNS names are
encoded as two-octet sequences. this caused a glitch in iterator
positioning when some lookups failed.
consider the case where we're searching for "\009" (represented
in a QP key as {0x03, 0x0c}) and a branch exists for "\000"
(represented as {0x03, 0x03}). we match on the 0x03, and continue
to search down. at the point where we find we have no match,
we need to pop back up to the branch before the 0x03 - which may
be multiple levels up the stack - before we position the iterator.
there were some structure names used in qpcache.c and qpzone.c that
were too similar to each other and could be confusing when debugging.
they have been changed as follows:
in qcache.c:
- changed_t was unused, and has been removed
- search_t -> qpc_search_t
- qpdb_rdatasetiter_t -> qpc_rditer_t
- qpdb_dbiterator_t -> qpc_dbiter_t
in qpzone.c:
- qpdb_changed_t -> qpz_changed_t
- qpdb_changedlist_t -> qpz_changedlist_t
- qpdb_version_t -> qpz_version_t
- qpdb_versionlist_t -> qpz_versionlist_t
- qpdb_search_t -> qpz_search_t
- qpdb_load_t -> qpz_search_t
when calling dns_qp_lookup() from qpcache, instead of passing
'foundname' so that a name would be constructed from the QP key,
we now just use the name field in the node data. this makes
dns_qp_lookup() run faster.
the same optimization has also been added to qpzone.
the documentation for dns_qp_lookup() has been updated to
discuss this performance consideration.
when the cache is over memory, we purge from the LRU list until
we've freed the approximate amount of memory to be added. this
approximation could fail because the memory allocated for nodenames
wasn't being counted.
add a dns_name_size() function so we can look up the size of nodenames,
then add that to the purgesize calculation.
in a cache database, unlike zones, NSEC3 records are stored in
the main tree. it is not necessary to maintain a separate 'nsec3'
tree, nor to have code in the dbiterator implementation to traverse
from one tree to another.
(if we ever implement synth-from-dnssec using NSEC3 records, we'll
need to revert this change. in the meantime, simpler code is better.)
the QP database doesn't support relative names as the RBTDB did, so
there's no need for a 'new_origin' flag or to handle `DNS_R_NEWORIGIN`
result codes.
- remove unneeded struct members and misleading comments.
- remove unused parameters for static functions.
- rename 'find_callback' to 'delegating' for consistency with qpzone;
the find callback mechanism is not used in QP databases.
