      Wait until "rndc dumpdb" completes · 6e3f812a
      Michał Kępień authored
      "rndc dumpdb" works asynchronously, i.e. the requested dump may not yet
      be fully written to disk by the time "rndc" returns.  Prevent false
      positives for the "serve-stale" system test by only checking dump
      contents after the line indicating that it is complete is written.

      Silence a Perl warning output by stop.pl · 91e5a99b
      Michał Kępień authored
      On Unix systems, the CYGWIN environment variable is not set at all when
      BIND system tests are run.  If a named instance crashes on shutdown or
      otherwise fails to clean up its pidfile and the CYGWIN environment
      variable is not set, stop.pl will print an uninitialized value warning
      on standard error.  Prevent this by using defined().

      Allow ifconfig to be called from any directory · 38301052
      Petr Menšík authored and Mark Andrews's avatar Mark Andrews committed
      ifconfig.sh depends on config.guess for platform guessing. It uses it to
      choose between ifconfig or ip tools to configure interfaces. If
      system-wide automake script is installed and local was not found, use
      platform guess. It should work well on mostly any sane platform. Still
      prefers local guess, but passes when if cannot find it.

      Stabilize "delzsk.example" zone checks · e02de04e
      Michał Kępień authored
      When a zone is converted from NSEC to NSEC3, the private record at zone
      apex indicating that NSEC3 chain creation is in progress may be removed
      during a different (later) zone_nsec3chain() call than the one which
      adds the NSEC3PARAM record.  The "delzsk.example" zone check only waits
      for the NSEC3PARAM record to start appearing in dig output while private
      records at zone apex directly affect "rndc signing -list" output.  This
      may trigger false positives for the "autosign" system test as the output
      of the "rndc signing -list" command used for checking ZSK deletion
      progress may contain extra lines which are not accounted for.  Ensure
      the private record is removed from zone apex before triggering ZSK
      deletion in the aforementioned check.
      
      Also future-proof the ZSK deletion progress check by making it only look
      at lines it should care about.

      Make ANSWER TTL capping checks stricter · a85cc414
      Michał Kępień authored
      For checks querying a named instance with "dnssec-accept-expired yes;"
      set, authoritative responses have a TTL of 300 seconds.  Assuming empty
      resolver cache, TTLs of RRsets in the ANSWER section of the first
      response to a given query will always match their authoritative
      counterparts.  Also note that for a DNSSEC-validating named resolver,
      validated RRsets replace any existing non-validated RRsets with the same
      owner name and type, e.g. cached from responses received while resolving
      CD=1 queries.  Since TTL capping happens before a validated RRset is
      inserted into the cache and RRSIG expiry time does not impose an upper
      TTL bound when "dnssec-accept-expired yes;" is set and, as pointed out
      above, the original TTLs of the relevant RRsets equal 300 seconds, the
      RRsets in the ANSWER section of the responses to expiring.example/SOA
      and expired.example/SOA queries sent with CD=0 should always be exactly
      120 seconds, never a lower value.  Make the relevant TTL checks stricter
      to reflect that.

      Relax ADDITIONAL TTL capping checks · 8baf8590
      Michał Kępień authored
      Always expecting a TTL of exactly 300 seconds for RRsets found in the
      ADDITIONAL section of responses received for CD=1 queries sent during
      TTL capping checks is too strict since these responses will contain
      records cached from multiple DNS messages received during the resolution
      process.
      
      In responses to queries sent with CD=1, ns.expiring.example/A in the
      ADDITIONAL section will come from a delegation returned by ns2 while the
      ANSWER section will come from an authoritative answer returned by ns3.
      If the queries to ns2 and ns3 happen at different Unix timestamps,
      RRsets cached from the older response will have a different TTL by the
      time they are returned to dig, triggering a false positive.
      
      Allow a safety margin of 60 seconds for checks inspecting the ADDITIONAL
      section of responses to queries sent with CD=1 to fix the issue.  A
      safety margin this large is likely overkill, but it is used nevertheless
      for consistency with similar safety margins used in other TTL capping
      checks.

      Fix message section checked in a TTL capping test · a597bd52
      Michał Kępień authored
      Commit c032c54d inadvertently changed
      the DNS message section inspected by one of the TTL capping checks from
      ADDITIONAL to ANSWER, introducing a discrepancy between that check's
      description and its actual meaning.  Revert to inspecting the ADDITIONAL
      section in the aforementioned check.

      Fix NTA-related races · 9a36a1bb
      Michał Kępień authored
      Changes introduced by commit 6b8e4d6e
      were incomplete as not all time-sensitive checks were updated to match
      revised "nta-lifetime" and "nta-recheck" values.  Prevent rare false
      positives by updating all NTA-related checks so that they work reliably
      with "nta-lifetime 12s;" and "nta-recheck 9s;".  Update comments as well
      to prevent confusion.

      Disable SERVFAIL cache for ns5 in the "mkeys" system test · 7c6bff3c
      Michał Kępień authored and Evan Hunt's avatar Evan Hunt committed
      The "check key refreshes are resumed after root servers become
      available" check may trigger a false positive for the "mkeys" system
      test if the second example/TXT query sent by dig is received by ns5 less
      than a second after it receives a REFUSED response to the upstream query
      it sends to ns1 in order to resolve the first example/TXT query sent by
      dig.  Since that REFUSED response from ns1 causes ns5 to return a
      SERVFAIL answer to dig, example/TXT is added to the SERVFAIL cache,
      which is enabled by default with a TTL of 1 second.  This in turn may
      cause ns5 to return a cached SERVFAIL response to the second example/TXT
      query sent by dig, i.e. make ns5 not perform full query processing as
      expected by the check.
      
      Since the primary purpose of the check in question is to ensure that key
      refreshes are resumed once initially unavailable root servers become
      available, the optimal solution appears to be disabling SERVFAIL cache
      for ns5 as doing that still allows the check to fulfill its purpose and
      it is arguably more prudent than always sleeping for 1 second.
