  • Added generic EDNS code for registering known EDNS option codes, bypassing the cache response stage and uniquifying mesh states. Four EDNS option lists were added to module_qstate (module_qstate.edns_opts_*) to store EDNS options from/to front/back side.
  • Added two flags to module_qstate (no_cache_lookup, no_cache_store) that control the modules' cache interactions.
  • Added code for registering inplace callback functions. The registered functions can be called just before replying with local data or Chaos, replying from cache, replying with SERVFAIL, replying with a resolved query, sending a query to a nameserver. The functions can inspect the available data and maybe change response/query related data (i.e. append EDNS options).
  • Updated Python module for the above.
  • Updated Python documentation.
  • Added views functionality.
  • Added qname-minimisation-strict config option.
  • Patch that resolves CNAMEs entered in local-data conf statements that point to data on the internet, from Jinmei Tatuya (Infoblox).
  • serve-expired config option: serve expired responses with TTL 0.
  • .gitattributes line for githubs code language display.
  • log-identity: config option to set sys log identity, patch from "Robin H. Johnson" (robbat2@gentoo.org).
  • Added stub-ssl-upstream and forward-ssl-upstream options.
  • Added local-zones and local-data bulk addition and removal functionality in unbound-control (local_zones, local_zones_remove, local_datas and local_datas_remove).

  • Patch for server.num.zero_ttl stats for count of expired replies, from Pavel Odintsov.
  • Fix failure to build on arm64 with no sbrk.
  • Set OpenSSL security level to 0 when using aNULL ciphers.
  • configure detects ssl security level API function in the autoconf manner. Every function on its own, so that other libraries (eg. LibreSSL) can develop their API without hindrance.
  • Fix #1154: segfault when reading config with duplicate zones.
  • Note that for harden-below-nxdomain the nxdomain must be secure, this means nsec3 with optout is insufficient.
  • Fix #1155: test status code of unbound-control in 04-checkconf, not the status code from the tee command.
  • Fix #1158: reference RFC 8020 "NXDOMAIN: There Really Is Nothing Underneath" for the harden-below-nxdomain option.
  • patch from Dag-Erling Smorgrav that removes code that relies on sbrk().
  • Make access-control-tag-data RDATA absolute. This makes the RDATA origin consistent between local-data and access-control-tag-data.
  • Fix NSEC ENT wildcard check. Matching wildcard does not have to be a subdomain of the NSEC owner.

  • Default for ssl-port is port 853, the temporary port assignment for secure domain name system traffic. If you used to rely on the older default of port 443, you have to put a clause in unbound.conf for that. The new value is likely going to be the standardised port number for this traffic.
  • ANY responses include DNAME records if present, as per Evan Hunt's remark in dnsop.

  • [bugzilla: 644 ]

    harden-algo-downgrade option, if turned off, fixes the reported excessive validation failure when multiple algorithms are present. If set to 'no', it allows the weakest algorithm to validate the zone.
  • stats reports tcp usage, of incoming-num-tcp buffers.
  • contrib/unbound_smf22.tar.gz: Solaris SMF installation/removal scripts. Contributed by Yuri Voinov.
  • Add ip-transparent config option for bind to non-local addresses.
  • Synthesize ANY responses from cache. Does not search exhaustively, but MX,A,AAAA,SOA,NS also CNAME.
  • unbound-control list_insecure command shows the negative trust anchors currently configured, patch from Jelte Jansen.
  • ratelimit feature, ratelimit: 1000, can be used to turn it on. It ratelimits recursion effort per zone. For particular names you can configure exceptions in unbound.conf.
  • Ratelimit does not apply to prefetched queries, and ratelimit-factor is default 10. Repeated normal queries get resolved and with prefetch stay in the cache.
  • unbound-control ratelimit_list lists high rate domains.
  • caps-whitelist in unbound.conf allows whitelist of loadbalancers that cannot work with caps-for-id or its fallback.
  • RFC 7553 RR type URI support, is now enabled by default.
  • cache-max-negative-ttl config option, default 3600.
  • Add local-zone type inform_deny, that logs query and drops answer.

Bug Fixes

  • Unbound exits with a fatal error when the auto-trust-anchor-file fails to be writable. This is seconds after startup. You can load a readonly auto-trust-anchor-file with trust-anchor-file. The file has to be writable to notice the trust anchor change, without it, a trust anchor change will be unnoticed and the system will then become inoperable.
  • DLV is going to be decommissioned. Advice to stop using it, and put text in the example configuration and man page to that effect.
  • Patch from Brad Smith that syncs compat/getentropy_linux with OpenBSD's version (2015-03-04).
  • 0x20 fallback improved: servfail responses do not count as missing comparisons (except if all responses are errors), inability to find nameservers does not fail equality comparisons, many nameservers does not try to compare more than max-sent-count, parse failures start 0x20 fallback procedure.
  • store caps_response with best response in case downgrade response happens to be the last one.
  • Document that incoming-num-tcp increase is good for large servers.
  • Fix lintian warning in unbound-checkconf man page (from Andreas Schulze).
  • Updated default keylength in unbound-control-setup to 3k.

    libunbound python3 related fixes (from Tomas Hozza); Use print_function also for Python2. libunbound examples: produce sorted output. libunbound-Python: libldns is not used anymore. Fix issue with Python 3 mapping of FILE* using file_py3.i from ldns.
  • Fix leaked dns64prefix configuration string.
  • Removed contrib/unbound_unixsock.diff, because it has been integrated, use control-interface: /path in unbound.conf.
  • Change syntax of particular validator error to be easier for machine parse, swap rrset and ip adres info so it looks like: validation failure <www.example.nl. TXT IN>: signature crypto failed from 2001:DB8:7:bba4::53 for <*.example.nl. NSEC IN>

  • This release has DNS64, DNSTAP, better random numbers and ub_ctx_add_ta_autr(), num.query.tcpout=value, flush_negative, unblock-lan-zones conf.
  • C.ROOT-SERVERS.NET has an IPv6 address, and we updated the root hints (patch from Anand Buddhdev).
  • Patch from Hannes Frederic Sowa for Linux 3.15 fragmentation option for DNS fragmentation defense.
  • unbound-control stats prints num.query.tcpout with number of TCP outgoing queries made in the previous statistics interval.
  • Patch from Jeremie Courreges-Anglas to use arc4random_uniform if available on the OS, it gets entropy from the OS.
  • Add unbound-control flush_negative that flushed nxdomains, nodata, and errors from the cache. For dnssec-trigger and NetworkManager, fixes cases where network changes have localdata that was already negatively cached from the previous network.
  • Contrib windows scripts from Yuri Voinov added to src/contrib: create_unbound_ad_servers.cmd: enters anti-ad server lists. unbound_cache.cmd: saves and loads the cache. Also warmup.cmd (and .sh): warm up the DNS cache with your MRU domains.
  • Added unbound-control-setup.cmd from Yuri Voinov to the windows unbound distribution set. It requires openssl installed in %PATH%.
  • Implement draft-ietf-dnsop-rfc6598-rfc6303-01.
  • Feature, unblock-lan-zones: yesno that you can use to make unbound perform and other reverse lookups normally, for use if unbound is running service for localhost on localhost.
  • unbound-host -D enabled dnssec and reads root trust anchor from the default root key file that was compiled in.
  • Add AAAA for B root server to default root hints.
  • unbound-control status reports if so-reuseport was successful.
  • so-reuseport is available on BSDs(such as FreeBSD 10) and OS/X.
  • arc4random in compat/ and getentropy, explicit_bzero, chacha for dependencies, from OpenBSD. arc4_lock and sha512 in compat. This makes arc4random available on all platforms, except when compiled with LIBNSS (it uses libNSS crypto random).
  • Patch from Dag-Erling Smorgrav that implements that: unbound -dd does not fork in the background and also logs to stderr.
  • DNS64 from Viagenie (BSD Licensed), written by Simon Perrault. Initial commit of the patch from the FreeBSD base (with its fixes). This adds a module (for module-config in unbound.conf) dns64 that performs DNS64 processing, see README.DNS64.
  • Patch add msg, rrset, infra and key cache sizes to stats command from Maciej Soltysiak.
  • DNSTAP support, with a patch from Farsight Security, written by Robert Edmonds. The --enable-dnstap needs libfstrm and protobuf-c. It is BSD licensed (see dnstap/dnstap.c). Also --with-libfstrm and --with-protobuf-c configure options.
  • type CDS and CDNSKEY types.
  • Updated the TCP_BACLOG from 5 to 256, so that the tcp accept queue is longer and more tcp connections can be handled.

  • Fixup out-of-directory compile with unbound-control-setup.sh.in.
  • Code cleanup patch from Dag-Erling Smorgrav, with compiler issue fixes from FreeBSD's copy of Unbound, he notes: Generate unbound-control-setup.sh at build time so it respects prefix and sysconfdir from the configure script. Also fix the umask to match the comment, and the comment to match the umask. Add const and static where needed. Use unions instead of playing pointer poker. Move declarations that are needed in multiple source files into a shared header. Move sldns_bgetc() from parse.c to buffer.c where it belongs. Introduce a new header file, worker.h, which declares the callbacks that all workers must define. Remove those declarations from libworker.h. Include the correct headers in the correct places. Fix a few dummy callbacks that don't match their prototype. Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK. Remove a useless printf which breaks reproducible builds. Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're no longer used. Add unbound-control-setup.sh to the list of generated files. The prototype for libworker_event_done_cb() needs to be moved from libunbound/libworker.h to libunbound/worker.h.
