- update to 4.5.4:
* Make sure that we pass the SOA along the NSEC(3) proof for
DS queries.
- no longer supports 32-bit arches -- requiers 64-bit time_t
- specfile cleanup - drop initrd cases
- build-require gcc7 on SLE-12 variant
- 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
- 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.
- update to 4.4.3:
Improvements
Use a short-lived NSEC3 hashes cache for denial validation.

- 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

- Remove escaping in case there was nothing to escape
83b746fd1d94c8742d8bd87a44beb44c154230c7
- Our logging infrastructure had a lot of locking
d1449e4d073595e1e1581804f121fc90e37158bf
- Reduce logging level of certain common messages, which locked
up synchronously logging systems

- 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

- Fixed broken _localstatedir
- 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 to
rec-channel.hh (this fixes building on OS X).
- sync permissions/ownership of home and config dir with the pdns
package
- added systemd support for 12.3 and newer
- update to 3.6.1
PowerDNS Recursor 3.6.0 could crash with a specific sequence of
packets. For more details, see Section 13, “PowerDNS Security
Advisory 2014-01: PowerDNS Recursor 3.6.0 can be crashed
remotely”. PowerDNS Recursor 3.6.1 was very well tested, and is
in full production already, so it should be a safe upgrade.

as ghost.
- update to version 3.2
The 3.2 release is the first major release of the PowerDNS
Recursor in a long time. Partly this is because 3.1.7.*
functioned very well, and delivered satisfying performance,
partly this is because in order to really move forward, some
heavy lifting had to be done.
This version of the PowerDNS Recursor contains a rather novel
form of lock-free multithreading, a situation that comes close to
the old '--fork' trick, but allows the Recursor to fully utilize
multiple CPUs, while delivering unified statistics and
operational control.
In effect, this delivers the best of both worlds: near linear
scaling, with almost no administrative overhead.

CVE-2009-4009
- update to version 3.1.7.1
This release consists entirely of fixes for tiny bugs that have
been reported over the past year. In addition, compatibility has
been restored with the latest versions of the gcc compiler and
the 'boost' libraries.
No features have been added, but some debugging code that very
slightly impacted performance (and polluted the console when
operating in the foreground) has been removed.
- Improved error messages when parsing zones for authoritative
serving (commit 1235).
- Better resilience against whitespace in configuration
(changesets 1237, 1240, 1242)
- Slight performance increase (commit 1378)
- Fix rare case where timeouts were not being reported to the
right query-thread (commit 1260)
- Fix compilation against newer versions of the Boost C++
libraries (commit 1381)
- Close very rare issue with TCP/IP close reporting ECONNRESET on
FreeBSD. Reported by Andrei Poelov in ticket 192.
- Silence debugging output (commit 1286).
- Fix compilation against newer versions of gcc (commit 1384)
- No longer set export-etc-hosts to 'on' on reload-zones.
Discovered by Paul Cairney, closes ticket 225.
- Sane default for the maximum cache size in the Recursor,
suggested by Roel van der Made (commit 1354).
- No longer exit because of the changed behaviour of the Solaris
'completion ports' in more recent versions of Solaris. Fix in
commit 1372, reported by Jan Gyselinck
- update to version 3.1.7
This version contains powerful scripting abilities, allowing
operators to modify DNS responses in many interesting ways. Among
other things, these abilities can be used to filter out malware
domains, to perform load balancing, to comply with legal and
other requirements and finally, to implement 'NXDOMAIN'
redirection.
It is hoped that the addition of Lua scripting will enable
responsible DNS modification for those that need it.
For more details about the Lua scripting, which can be modified,
loaded and unloaded at runtime, see Section 12.6. Many thanks are
due to the #lua irc channel, for excellent near-realtime Lua
support. In addition, a number of PowerDNS users have been
enthousiastically testing prereleases of the scripting support,
and have found and solved many issues.
- In 3.1.5 and 3.1.6, an authoritative server could continue to
renew its authority, even though a domain had been delegated to
other servers in the meantime.
- In the rare cases where this happened, and the old servers were
not shut down, the observed effect is that users were fed
outdated data.
- Bug spotted and analysed by Darren Gamble, fix in commit 1182
and commit 1183.
- Thanks to long time PowerDNS contributor Stefan Arentz, for the
first time, Mac OS X 10.5 users can compile and run the
PowerDNS Recursor! Patch in commit 1185.
- Sten Spans spotted that for outgoing TCP/IP queries, the
query-local-address setting was not honored. Fixed in commit
1190.
- rec_control wipe-cache now also wipes domains from the negative
cache, hurrying up the expiry of negatively cached records.
Suggested by Simon Kirby, implemented in commit 1204.
- When a forwarder server is configured for a domain, using the
forward-zones setting, this server IP address was filtered
using the dont-query setting, which is generally not what is
desired: the server to which queries are forwarded will often
live in private IP space, and the operator should be trusted to
know what he is doing. Reported and argued by Simon Kirby, fix
in commit 1211.
- Marcus Rueckert of OpenSUSE reported that very recent gcc
versions emitted a (correct) warning on an overly complicated
line in syncres.cc, fixed in commit 1189.
- Stefan Schmidt discovered that the netmask matching code, used
by the new Lua scripts, but also by all other parts of
PowerDNS, had problems with explicit '/32' matches. Fixed in
commit 1205.

* this version contains powerful scripting abilities, allowing
operators to modify DNS responses in many interesting ways.
Among other things, these abilities can be used to filter out
malware domains, to perform load balancing, to comply with legal
and other requirements and finally, to implement 'NXDOMAIN'
redirection.
* number of bugfixes
- dropped obsoleted patches:
(svn_fixes.patch) (make_it_compile.patch)
- backport the fixes from 3.1.6
- The new high-quality random generator was not used for all
random numbers, especially in source port selection.
(bnc#375400)
- fix issue resolving popular domains where one of the
nameservers is suffering from a timeout.
- added pdns-recursor-3.1.6_make_it_compile.patch:
missing include broke build
- added pdns-recursor-3.1.6_parentheses_warning.patch:
fix small warning about missing parentheses (disabled for now)
- updated to version 3.1.5
New features:
* Implemented rec_control command get uptime
* The Recursor Authorative component, meant for having
the Recursor serve some zones authoritatively, now supports
$INCLUDE and $GENERATE.

larger amounts of zones which should be forwarded
to another nameserver.
* Both forward-zones and forward-zones-file can now specify
multiple forwarders per domain.
* Sten Spans contributed allow-from-file. This feature allows
the Recursor to read access rules from a (large) file.
