providing resilience against connectivity problems towards
authoritative servers.
* Optional Record Locking has been implemented, providing an extra
layer of protection against spoofing attempts at the price of

* Mon May 30 2022 Michael Ströder <michael@stroeder.com>
- update to 4.7.0
* A configurable way of adding Additional records to answers sent
to the client, so the client does not have to ask for these
records.
* The step sizes for Query Minimization are now computed following to
guidelines in [2]RFC 9156.
* The Recursor now schedules tasks to resolve IPv6 addresses of name
servers not learned by glue records. This has the consequence that,
if applicable, name servers will be contacted over IPv6 more often.
* An experimental implementation of unilateral [3]DoT probing. This
allows the Recursor to learn if a an authoritative servers supports
DoT.
* Recursor has gained a way to fall back to the parent NS set if
contacting servers in the child NS set does not lead to an answer.
This works around some broken authoritative servers configurations.
* ZONEMD validation of the zones retrieved by the [5]Zone to Cache,
providing integrity guarantees for the zone retrieved.

zones from a remote server if the network path to the server
is not trusted. (bsc#1197525, CVE-2022-27227)
* Fri Dec 17 2021 Michael Ströder <michael@stroeder.com>
- update to 4.6.0
Compared to the previous major (4.5) release of PowerDNS Recursor, this
release contains several sets of changes:
* The ability to flush records from the caches on a incoming
notify requests.
* A rewrite of the outgoing TCP code, adding both re-use of
connections and support for DoT to authoritative servers or
forwarders.
* Many improvements in the area of metrics: more metrics are
collected and more metrics are now exported in a Prometheus
friendly way.
* A new Zone to Cache function that will retrieve a zone (using
AXFR, HTTP, HTTPS or a local file) periodically and insert the
contents into the record cache, allowing the cache to be always hot
for a zone. This can be used for the root or any other zone.
* An experimental Event Tracing function, providing insight into
the time taken by the steps in the process of resolving a name.
* Fri Nov 05 2021 Michael Ströder <michael@stroeder.com>

- no longer supports 32-bit arches -- requiers 64-bit time_t
- specfile cleanup - drop initrd cases
- build-require gcc7 on SLE-12 variant
* Wed Jun 09 2021 Michael Ströder <michael@stroeder.com>
- update to 4.5.2:
* default value of nsec3-max-iterations[1] has been lowered to 150
* fixed issue affecting the "refresh almost expired" function
* Tue May 11 2021 Michael Ströder <michael@stroeder.com>
- update to 4.5.1:
- Main changes:
* Dropped support for 32-bit platforms!
* Rewrite of the way zone cuts are determined, reducing the number of
outgoing queries by up to 17% when doing DNSSEC validation while reducing
the CPU usage more than 20% .
* Added implementation of EDNS0 padding (RFC 7830) for answers sent to clients.
* Added implementation of RFC 8198[2]: Aggressive use of DNSSEC-Validated Cache.
* Added a cache of non-resolving nameservers.
* Re-worked negative cache that is shared between threads.
* Added support for Extended DNS Errors (RFC 8914[5]).
* A "refresh almost expired records" (also called "refetch") mechanism[8]
has been introduced to keep the record cache warm.
- Other new features and improvements:
* The complete protobuf and dnstap logging code has been rewritten to
have much smaller performance impact.
* We have introduced non-offensive synonyms for words used in
settings. See the upgrade[9] guide.
* The default minimum TTL[10] override has been changed from 0 to 1.
* The spoof-nearmiss-max setting[11]'s default has been changed to 1.
This has the consequence that the Recursor will switch to do TCP
queries to authoritative nameservers sooner as an effective measure
against many spoofing attacks.
* Incoming queries over TCP now also use the packet cache, providing
another performance increase.
* File written to by the rec_control command are new opened by the
command itself. It is also possible to write the content to the
standard output stream by using a hyphen as file name.
* TCP FastOpen (RFC 7413[12]) support for outgoing TCP connections to
authoritative servers and forwarders.
* Wed Mar 31 2021 Adam Majer <adam.majer@suse.de>
- update to 4.4.3:

Handle failure to start the web server more gracefully.
Test that we correctly cap the answer’s TTL in expanded wildcard cases.
Fix the gathering of denial proof for wildcard-expanded answers.
Make sure we take the right minimum for the packet cache TTL data in the SERVFAIL case.

* Names encountered while resolving CNAMEs are now subject to RPZ
processing.
* More detailed information about RPZ handling is now available while
tracing, in Lua and in the protobuf logging messages.
* To allow more efficient use, the record cache is now shared between
threads.
* A routing tag[3] can be added in Lua code, which will be used as an
additional record cache key instead of an EDNS subnet mask,
enabling for a simpler record cache structure which will enhance
query processing where the EDNS subnet mask is relevant.
* The Proxy Protocol version 2 has been implemented to allow for a
structured exchange of information between a client (typically
dnsdist) and the Recursor.

a903b39cfe7364c56324038264d3db50b8cece87
- Our nameserver-loop detection carried around a lot of baggage
for complex domain names, plus did not differentiate IPv4 and
IPv6 well enough 891fbf888ccac074e3edc38864641ca774f2f03c
- Prioritize new queries over nameserver responses, improving
latency under query bursts

173d790ead08f67733010ca4c6fc404a040fe699
Bugs fixed:
- IPv6 outgoing queries had a disproportionate effect on our
query load. Fixed in 76f190f2a0877cd79ede2994124c1a58dc69ae49
and beyond.
- rec_control gave incorrect output on a timeout
12997e9d800734da51b808767e1e2477244c30eb
- When using the webserver AND having an error in the Lua script,
recursor could crash during startup
62f0ae62984adadab687c23fe1b287c1f219b2cb
- Hugely long version strings would trip up security polling
18b7333828a1275ae5f5574a9c8330290d8557ff (Kees Monshouwer)
- The 'remotes' ringbuffer was sized incorrectly
f8f243b01215d6adcb59389f09ef494f1309041f
- Cache sizes had an off-by-one scaling problem, with the wrong
number of entries allocated per thread
f8f243b01215d6adcb59389f09ef494f1309041f
- Our automatic file descriptor limit raising was attempted
* after* setuid, which made it a lot less effective. Found and
fixed by Aki Tuomi a6414fdce9b0ec32c340d1f2eea2254f3fedc1c1
- Timestamps used for dropping packets were occasionaly wrong
183eb8774e4bc2569f06d5894fec65740f4b70b6 and
4c4765c104bacc146533217bcc843efb244a8086 (RC2) with thanks to
Winfried for debugging.
- In RC1, our new DoS protection measures would crash the
Recursor if too many root servers were unreachable.

- update to upstream release 3.6.2 (boo# 906583) CVE-2014-8601
This is a bugfix update to 3.6.1.
A list of changes since 3.6.1 follows.
* gab14b4f: expedite servfail generation for ezdns-like
failures (fully abort query resolving if we hit more than
50 outqueries)
* g42025be: PowerDNS now polls the security status of a
release at startup and periodically. More detail on this
feature, and how to turn it off, can be found in Section 2,
"Security polling".
* g5027429: We did not transmit the right 'local' socket
address to Lua for TCP/IP queries in the recursor. In
addition, we would attempt to lookup a filedescriptor that
wasn't there in an unlocked map which could conceivably
lead to crashes. Closes t1828, thanks Winfried for
reporting
* g752756c: Sync embedded yahttp copy. API: Replace HTTP
Basic auth with static key in custom header
* g6fdd40d: add missing #include <pthread.h> to
rec-channel.hh (this fixes building on OS X).
