This incorporates the following changes, plus a new configure
option "--enable-rrl" to turn them on:
3575. [func] Changed the logging category for RRL events from
'queries' to 'query-errors'. [RT #33540]
3554. [bug] RRL failed to correctly rate-limit upward
referrals and failed to count dropped error
responses in the statistics. [RT #33225]
3545. [bug] RRL slip behavior was incorrect when set to 1.
[RT #33111]
3518. [bug] Increase the size of dns_rrl_key.s.rtype by one bit
so that all dns_rrl_rtype_t enum values fit regardless
of whether it is teated as signed or unsigned by
the compiler. [RT #32792]
3494. [func] DNS RRL: Blunt the impact of DNS reflection and
amplification attacks by rate-limiting substantially-
identical responses. To enable, use "configure
--enable-rrl". [RT #28130]
3505. [bug] When setting "max-cache-size" and "max-acache-size",
larger values than 4 gigabytes could not be set
explicitly, though larger sizes were available
when setting cache size to 0. This has been
corrected; the full range is now available.
[RT #32358]
(cherry picked from commit 2a184ff865)
3501. [func] zone-statistics now takes three options: full,
terse, and none. "yes" and "no" are retained as
synonyms for full and terse, respectively. [RT #29165]
(cherry picked from commit 40a7e85f3e)
3496. [func] Improvements to RPZ performance. The "response-policy"
syntax now includes a "min-ns-dots" clause, with
default 1, to exclude top-level domains from
NSIP and NSDNAME checking. --enable-rpz-nsip and
--enable-rpz-nsdname are now the default. [RT #32251]
Response policy (rpz) changes to
- add zone statistics
- speed up by adding min-ns-dots to the response-policy syntax
with a default of 1
- detect and reject policy zones with a database other than rbt
only rbtdb has rpz hooks
- allow empty response-policy{} statement
- make --enable-rpz-nsip and --enable-rpz-nsdname the default
range of possible values. Address portability issues.
[RT #31938]
Squashed commit of the following:

address hpux sscanf issues, iterations is a 16 bit field, use %hu rather than %hhd as the values are unsigned

3316. [tuning] Improved locking performance when recursing.
[RT #28836]
3315. [tuning] Use multiple dispatch objects for sending upstream
queries; this can improve performance on busy
multiprocessor systems by reducing lock contention.
[RT #28605]
Add
- optional "recursive-only yes|no" to the response-policy statement
- optional max-policy-ttl to limit the lies that "recursive-only no"
can introduce into resolvers' caches
- test that queries with RD=0 are not rewritten by default
- performance smoke test
Change encoding of PASSTHRU action to "rpz-passthru".
(The old encoding is still accepted.)
Fix rt26180 assert botch in zone_findrdataset() in this branch
as well.
Fix missing signatures on NOERROR results despite RPZ hits
when there are signatures and the client asks for DNSSEC,
inline-signing zone could stall when the server
was restarted. [RT #27344]
3263. [bug] "rndc sync" did not affect the unsigned side of an
inline-signing zone. [RT #27337]
3255. [func] No longer require that a empty zones be explicitly
enabled or that a empty zone is disabled for
RFC 1918 empty zones to be configured. [RT #27139]
