Authoritative Server 3.3 released!

Jul 5, 2013

This a stability, bugfix and conformity update to 3.2. It improves interoperability with various validators, either through bugfixes or by catering to their needs beyond the specifications.

Changes between RC2 and final:


Changes between RC1 and RC2:

  • Added dnstcpbench tool, by popular demand.
  • We always shipped a static tools RPM; we now have a similar Debian package. All packages have been cleaned up a bit, and the binary collections are now consistent between RPM and Deb. New: pass –enable-tools to configure to have the tools included in ‘make all’ and ‘make install’.
  • commit 4d2e3f5: add selinux policy files
  • We would sometimes send a single NULL byte, or nothing at all, instead of an OPT record. Fixed in commit bf7f822commit 063076bcommit 90d361d.
  • commit 2ee9ba2: expand any-to-tcp to direct RRSIG queries
  • commit 5fff084commit e38ef51: drop no-op flag strict-rfc-axfrs, thanks Jelte Jansen.
  • commit f3d8902commit 7c0b859commit 5eea730: Implement MINFO qtype for better interaction when slaving zones from NSD (that contain MINFO). Thanks to Jelte Jansen.
  • commit 8655a42commit bf79c6acommit 38c941b: SRV record can have a ‘.’ as final field, from which we would dutifully strip the trailing ., leaving void, confusing everything. We now remove the trailing . in the right place, and not if we are trying to server ‘.’. Again thanks to Jelte & SIDN for catching this.
  • commit 70d5a66: improve error message in ill formed unknown record type, thanks Jelte Jansen for reporting.
  • commit 3640473: Built in webserver can now listen on IPv6, fixes ticket 843. Also silences some useless messages about timeouts.
  • commit 7db735ccommit d72166c: CHANGES BEHAVIOUR: before we launch, check if we can connect to the controlsocket we are about to obliterate. If it works, abort. Fixes ticket 841 and changes standing behaviour. There might be circumstances where PowerDNS now refuses to start, where it previously would. However, starting and making our previous instance mute wasn’t good.
  • commit 9130f9e: correctly refuse out-of-zone data in bindbackend, closes ticket 845
  • commit 3363ef7: initialise server-id after all parsing is done, instead of half way through. Fixes situations where server-id was emptied explicitly. Reported by Wouter de Jong
  • commit cd4f253: bump boost requirement, thanks Wouter de Jong
  • commit 58cad74: Update pdns auth init script so it works on wheezy
  • commit 8714c9c: clang fixes by Aki Tuomi, thanks!
  • commit 146601d: stretch supermasters.ip for IPv6, thanks Dennis Krul
  • commit 1a5c5f9: various remotebackend improvements by Aki Tuomi
  • commit 6ab1a11: make sure systemd starts PowerDNS after relevant databases have been started, thanks Morten Stevens.
  • commit 606018fcommit ee5e175commit c76f6f4: check scopeMask of answer packet, not of query packet!
  • commit 2b18bcf: Added warning if trailing dot is used, thanks Aki Tuomi.
  • commit 16cf913: make superfluous ‘bind’ NSEC3 record optional


New features and important changes since 3.2 (these changes are in RC1 and up):

  • commit 04576eecommit b0e15c8: Implement pdnssec increase-serial, thanks Ruben d’Arco.
  • commit cee857b: PowerDNS now sets additional groups while dropping privileges.
  • commit 7796a3b: Merge support for include-dir directive, thanks Aki Tuomi!
  • commit d725755: make pdns-static Conflict with pdns-server, closes ticket 640
  • commit c0d5504: pdnssec now emits ‘INSERT INTO domain ..’ queries when running without named.conf, thanks Ruben d’Arco.
  • commit a1d6b0c: Older versions of the BIND 9 validating recursor need a superfluous NSEC3 record on positive wildcard responses. We now send this extra NSEC3. Closes ticket 814.
  • commit 07bf35d: catch a lot more errors in pdnssec and report them. Fixes ticket 588.
  • commit 032e390: make pdnssec exit with 1 on some error conditions, closes ticket 677
  • commit 4af49b8commit 4cec6ac: add ability to create an ‘active’ or inactive key using add-zone-key and import-zone-key, plus silenced some debugging. Fixes ticket 707.
  • commit fae4167: Compiling against Lua 5.2 (–with-lua=lua5.2) now disables some code used for regression testing, instead of breaking during compile. This means that Lua 5.2 can be used in production.
  • commit abc8f3f357f6a7: Implement the new any-to-tcp option that, when set, always replies with a truncated response (TC=1) to ANY queries, forcing them to use TCP.
  • commit 496073b: Since 3.0, pdnssec secure-zone has always generated 3 keys: one KSK and two ZSK, with one ZSK active. For most, if not almost all, users, this inactive ZSK is never used. We now no longer generate this useless ZSK. The resulting smaller DNSKEY RRset improves interoperability with certain validators. Closes ticket 824.
  • commit df55450: Non-DNSSEC ANY queries no longer get sent DNSSEC records. This improves interoperability with some old resolvers. Patch by Kees Monshouwer.
  • commit 04b4bf6: Merge support for not using opt-out with NSEC3. Many thanks to Kees Monshouwer.
  • commit 8db49a6: We now try not to NOTIFY ourselves. In convoluted cases involving REUSE_PORT and binding to and ::, it might be possible that we guess wrong, in which case you can set prevent-self-notification to off.


Important bug fixes:

  • commit 63e365d: don’t mess up encoding when copying qname from question to answer in packetcache. Based on reports&debugging by Jimmy Bergman (sigint), Daniel Norman (Loopia) and the fine people at ISC. This avoids most issues related to BIND 9 erroneously blacklisting PowerDNS for lack of EDNS support.
  • commit 3526186: fix backslash handling in TXT parser, includes test. Thanks Jan-Piet Mens.
  • commit 830281faef7330: Accept chars >127 (‘high ASCII’) in TXT records, closing ticket 541 and 723.
  • commit feef1ec: fix missing NSEC3 for secure delegation, thanks Kees Monshouwer, closes ticket 682
  • commit b61e407: around Thursday midnight, during signature rollovers, we would update the SOA serial too early. Fixed by reverting commit d90efbf, adding 7 days margin to inception. Fix by Kees Monshouwer.
  • commit ff64750: make sure mixed-case queries get a correct apex NSEC3 type bitmap
  • commit 4b153d8: always lowercase next name in NSEC to avoid interop troubles with validators, thanks Marco Davids&Matthijs Mekking.

  • commit 49977c6: fix bug in boost.m4 where it insists on setting -L, causing useless RPATH in our binaries. Closes ticket 728
  • commit 62ac758: use PolarSSL for MD5 hashing instead of shipping our own copy of md5 hashing code, thanks Aki Tuomi.
