./net/unbound, DNS resolver and recursive server

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.8.3, Package name: unbound-1.8.3, Maintainer: pettai

Unbound is an implementation of a DNS resolver. It provides a library
similiar to libresolv that can be used for synchronous and asynchronous
DNS look ups. It also provides a caching-only (recursive) DNS server.

Unbound has full support for IPv6 and DNSSEC validation.

Update unbound to version 1.8.2

Pkgsrc changes:
 * Re-position configure diff.

Upstream changes:

Features
- Add fast-server-permil and fast-server-num options.
- Deprecate low-rtt and low-rtt-permil options.
- Change fast-server-num default to 3.
- Fix #4154: make ECS_MAX_TREESIZE configurable, with
  the max-ecs-tree-size-ipv4 and max-ecs-tree-size-ipv6 options.
- Fix #4190: Please create a "ANY" deny option, adds the option
  deny-any: yes in unbound.conf.  This responds with an empty message
  to queries of type ANY.
- Fix #4126: RTT_band too low on VSAT links with 600+ms latency,
  adds the option unknown-server-time-limit to unbound.conf that
  can be increased to avoid the problem.
- Add min-client-subnet-ipv6 and min-client-subnet-ipv4 options.
- Support SO_REUSEPORT_LB in FreeBSD 12 with the so-reuseport: yes
  option in unbound.conf.

Bug Fixes
- dnscrypt.c removed sizeof to get array bounds.
- Fix testlock code to set noreturn on error routine.
- Remove unused variable from contrib fastrpz/rpz.c and
  remove unused diagnostic pragmas that themselves generate warnings
- clang analyze test is used only when assertions are enabled.
- Squelch EADDRNOTAVAIL errors when the interface goes away,
  this omits 'can't assign requested address' errors unless
  verbosity is set to a high value.
- Set default for so-reuseport to no for FreeBSD.  It is enabled
  by default for Linux and DragonFlyBSD.  The setting can
  be configured in unbound.conf to override the default.
- iana port update.
- Squelch log of failed to tcp initiate after TCP Fastopen failure.
- Fix #4192: unbound-control-setup generates keys not readable by
  group.
- check that the dnstap socket file can be opened and exists, print
  error if not.

- remade makefile dependencies.
- Fix #4152: Logs shows wrong time when using log-time-ascii: yes.
- Scrub NS records from NXDOMAIN responses to stop fragmentation
  poisoning of the cache.
- Scrub NS records from NODATA responses as well.
- Add patch from Jan Vcelak for pythonmod,
  add sockaddr_storage getters, add support for query callbacks,
  allow raw address access via comm_reply and update API documentation.
- Removed compile warnings in pythonmod sockaddr routines.
- With ./configure --with-pyunbound --with-pythonmodule
  PYTHON_VERSION=3.6 or with 2.7 unbound can compile and unit tests
  succeed for the python module.
- pythonmod logs the python error and traceback on failure.
- ignore debug python module for test in doxygen output.
- review fixes for python module.
- Fix #4209: Crash in libunbound when called from getdns.
- auth zone zonefiles can be in a chroot, the chroot directory
  components are removed before use.
- Fix that empty zonefile means the zonefile is not set and not used.
- Fix to not set GLOB_NOSORT so the unbound.conf include: files are
  sorted and in a predictable order.
- Fix #4193: Fix that prefetch failure does not overwrite valid cache
  entry with SERVFAIL.
- Fix DNS64 to not store intermediate results in cache, this avoids
  other threads from picking up the wrong data.  The module restores
  the previous no_cache_store setting when the the module is finished.
- Fix #4208: 'stub-no-cache' and 'forward-no-cache' not work.
- New and better fix for Fix #4193: Fix that prefetch failure does
  not overwrite valid cache entry with SERVFAIL.
- auth-zone give SERVFAIL when expired, fallback activates when
  expired, and this is documented in the man page.
- stat count SERVFAIL downstream auth-zone queries for expired zones.
- Put new logos into windows installer.
- Fix windows compile for new rrset roundrobin fix.
- Update contrib fastrpz patch for latest release.
- Fix chroot auth-zone fix to remove chroot prefix.
- windows icon updated.

Log message:
Update unbound to version 1.8.1

Upstream changes:

Features:
- Perform TLS SNI indication of the host that is being contacted
  for DNS over TLS service.  It sets the configured tls auth name.
  This is useful for hosts that apart from the DNS over TLS services
  also provide other (web) services.

Bug Fixes:
- More explicitly mention the type of ratelimit when applying
  ip-ratelimit.
- Fix spelling error in header, from getdns commit by Andreas Gelmini.
- iana port update.
- Fixed unused return value warnings in contrib/fastrpz.patch for
  asprintf.
- Fix to squelch respip warning in unit test, it is printed at
  higher verbosity settings.
- Fix spelling errors.
- Fix initialisation in remote.c
- Fix seed for random backup code to use explicit zero when wiped.
- exit log routine is annotated as noreturn function.
- free memory leaks in config strlist and str2list insert functions.
- do not move unused argv variable after getopt.
- Remove unused if clause in testcode.
- in testcode, free async ids, initialise array, and check for null
  pointer during test of the test.  And use exit for return to note
  irregular program stop.
- Free memory leak in config strlist append.
- make sure nsec3 comparison salt is initialized.
- unit test has clang analysis.
- remove unused variable assignment from iterator scrub routine.
- check for null in delegation point during iterator refetch
  in forward zone.
- neater pointer cast in libunbound context quit routine.
- initialize statistics totals for printout.
- in authzone check that node exists before adding rrset.
- in unbound-anchor, use readwrite memory BIO.
- assertion in autotrust that packed rrset is formed correctly.
- Fix memory leak when message parse fails partway through copy.
- remove unused udpsize assignment in message encode.
- nicer bio free code in unbound-anchor.
- annotate exit functions with noreturn in unbound-control.
- Fix compile on Mac for unbound, provide explicit_bzero when libc
  does not have it.
- Fix unbound for openssl in FIPS mode, it uses the digests with
  the EVP call contexts.
- Fix that with harden-below-nxdomain and qname minisation enabled
  some iterator states for nonresponsive domains can get into a
  state where they waited for an empty list.
- Stop UDP to TCP failover after timeouts that causes the ping count
  to be reset by the TCP time measurement (that exists for TLS),
  because that causes the UDP part to not be measured as timeout.
- Fix #4156: Fix systemd service manager state change notification.
- Fix #4149: Add SSL cleanup for tcp timeout.
- Fix #4188: IPv6 forwarders without ipv6 result in SERVFAIL, fixes
  qname minimisation with a forwarder when connectivity has issues
  from rejecting responses.

Log message:
Update unbound to version 1.8.0

Upstream changes:

Features
- unbound-control auth_zone_reload _zone_ option rereads the zonefile.
- unbound-control auth_zone_transfer _zone_ option starts the probe
  sequence for a master to transfer the zone from and transfers when
  a new zone version is available.
- num.queries.tls counter for queries over TLS.
- log port number with err_addr logs.
- dns64-ignore-aaaa: config option to list domain names for which the
  existing AAAA is ignored and dns64 processing is used on the A
  record.
- Fix #4112: Fix that unbound-anchor -f /etc/resolv.conf will not pass
  if DNSSEC is not enabled.  New option -R allows fallback from
  resolv.conf to direct queries.
- Note RFC8162 support.  SMIMEA record type can be read in by the
  zone record parser.
- Patches from Jim Hague (Sinodun) for EDNS KeepAlive.
- Add config tcp-idle-timeout (default 30s). This applies to
  client connections only; the timeout on TCP connections upstream
  is unaffected.
- Add edns-tcp-keepalive and edns-tcp-keepalive timeout options
  and implement option in client responses.
- Add delay parameter to streamtcp, -d secs.
  To be used when testing idle timeout.
- Expose if a query (or a subquery) was ratelimited (not src IP
  ratelimiting) to libunbound under 'ub_result.was_ratelimited'.
  This also introduces a change to 'ub_event_callback_type' in
  libunbound/unbound-event.h.
- Patch to implement tcp-connection-limit from Jim Hague (Sinodun).
  This limits the number of simultaneous TCP client connections
  from a nominated netblock.
- Fix #4142: unbound.service.in: improvements and fixes.
  Add unit dependency ordering (based on systemd-resolved).
  Add 'CAP_SYS_RESOURCE' to 'CapabilityBoundingSet' (fixes warnings
  about missing privileges during startup). Add 'AF_INET6' to
  'RestrictAddressFamilies' (without it IPV6 can't work). From
  Guido Shanahan.
- unbound-checkconf checks if modules exist and prints if they are
  not compiled in the name of the wrong module.
- Patch for stub-no-cache and forward-no-cache options that disable
  caching for the contents of that stub or forward, for when you
  want immediate changes visible, from Bjoern A. Zeeb.
- Upgraded crosscompile script to include libunbound DLL in the
  zipfile.
- Set libunbound to increase current, because the libunbound change
  to the event callback function signature.  That needs programs,
  that use it, to recompile against the new header definition.
- log-servfail: yes prints log lines that say why queries are
  returning SERVFAIL to clients.
- log-local-actions: yes option for unbound.conf that logs all the
  local zone actions, a patch from Saksham Manchanda (Secure64).
- #4146: num.query.subnet and num.query.subnet_cache counters.
- #4140: Expose repinfo (comm_reply) to the inplace_callbacks. This
  gives access to reply information for the client's communication
  point when the callback is called before the mesh state (modules).
  Changes to C and Python's inplace_callback signatures were also
  necessary.
- Set defaults to yes for a number of options to increase speed and
  resilience of the server.  The so-reuseport, harden-below-nxdomain,
  and minimal-responses options are enabled by default.  They used
  to be disabled by default, waiting to make sure they worked.  They
  are enabled by default now, and can be disabled explicitly by
  setting them to "no" in the unbound.conf config file.  The reuseport
  and minimal options increases speed of the server, and should be
  otherwise harmless.  The harden-below-nxdomain option works well
  together with the recently default enabled qname minimisation, this
  causes more fetches to use information from the cache.
- Added serve-expired-ttl and serve-expired-ttl-reset options.

Bug Fixes
- Windows example service.conf edited with more windows specific
  configuration.
- #4108: systemd reload hang fix.
- Fix usage printout for unbound-host, hostname has to be last
  argument on BSDs and Windows.
- Partial fix for permission denied on IPv6 address on FreeBSD.
- Fix that auth-zone master reply with current SOA serial does not
  stop scan of masters for an updated zone.
- Fix that auth-zone does not start the wait timer without checking

  in the ssl library.
- Fix that ratelimit and ip-ratelimit are applied after reload of
  changed config file.
- Resize ratelimit and ip-ratelimit caches if changed on reload.
- Fix #4129 unbound-control error message with wrong cert permissions
  is too cryptic.
- Fix #4130: print text describing -dd and unbound-checkconf on
  config file read error at startup, the errors may have been moved
  away by the startup process.
- Fix #4131: for solaris, error YY_CURRENT_BUFFER undeclared.

- Implement progressive backoff of TCP idle/keepalive timeout.
- Fix 'make depend' to work when build dir is not project root.
- Fix #4139: Fix unbound-host leaks memory on ANY.
- Fix to remove systemd sockaddr function check, that is not
  always present.  Make socket activation more lenient.  But not
  different when socket activation is not used.

  released tarball and build host.  Fix to unconditionally call
  destroy in daemon.c.
- Make capsforid fallback QNAME minimisation aware.
- document --enable-subnet in doc/README.

  enabled.
- Fix lintflags for lint on FreeBSD.
- Fix that a local-zone with a local-zone-type that is transparent
  in a view with view-first, makes queries check for answers from the
  local-zones defined outside of views.

Log message:
Update unbound to version 1.7.3

Upstream changes:

Features
- #4102 for NSD, but for Unbound.  Named unix pipes do not use
  certificate and key files, access can be restricted with file and
  directory permissions.  The option control-use-cert is no longer
  used, and ignored if found in unbound.conf.
- Rename tls-additional-ports to tls-additional-port, because every
  line adds one port.

Bug Fixes
- Don't count CNAME response types received during qname minimisation
  as query restart.
- #4100: Fix stub reprime when it becomes useless.
- Fix crash if ratelimit taken into use with unbound-control
  instead of with unbound.conf.
- Patch to fix openwrt for mac os build darwin detection in configure.
- #4103: Fix that auth-zone does not insist on SOA record first in
  file for url downloads.
- Fix that first control-interface determines if TLS is used.  Warn
  when IP address interfaces are used without TLS.

- Fix unbound-checkconf for control-use-cert.
- Fix for unbound-control on Windows and set TCP socket parameters
  more closely.
- Fix windows unbound-control no cert bad file descriptor error.

Log message:
Upgrade unbound to version 1.7.1.

Upstream changes:

Features
- Add --with-libhiredis, unbound support for a new cachedb
  backend that uses a Redis server as the storage.  This
  implementation depends on the hiredis client library
  (https://redislabs.com/lp/hiredis/).
  And unbound should be built with both --enable-cachedb and
  --with-libhiredis[=PATH] (where $PATH/include/hiredis/hiredis.h
  should exist).  Patch from Jinmei Tatuya (Infoblox).
- Create additional tls service interfaces by opening them on other
  portnumbers and listing the portnumbers as additional-tls-port: nr.
- ED448 support.
- num.query.authzone.up and num.query.authzone.down statistics counters.
- Accept both option names with and without colon for get_option
  and set_option.
- low-rtt and low-rtt-pct in unbound.conf enable the server selection
  of fast servers for some percentage of the time.
- num.query.aggressive.NOERROR and num.query.aggressive.NXDOMAIN
  statistics counters.
- allow-notify: config statement for auth-zones.
- Can set tls authentication with forward-addr: IP#tls.auth.name
  And put the public cert bundle in tls-cert-bundle: "ca-bundle.pem".
  such as forward-addr: 9.9.9.9@853#dns.quad9.net or
  1.1.1.1@853#cloudflare-dns.com
- list_auth_zones unbound-control command.
- Added root-key-sentinel support

Bug Fixes
- Fix #3727: Protocol name is TLS, options have been renamed but
  documentation is not consistent.
- Check IXFR start serial.
- Fix typo in documentation.
- Fix #3736: Fix 0 TTL domains stuck on SERVFAIL unless manually
  flushed with serve-expired on.
- Fix #3817: core dump happens in libunbound delete, when queued
  servfail hits deleted message queue.
- corrected a minor typo in the changelog.
- move htobe64/be64toh portability code to cachedb.c.
- iana port update.
- Do not use cached NSEC records to generate negative answers for
  domains under DNSSEC Negative Trust Anchors.
- Fix unbound-control get_option aggressive-nsec
- Check "result" in dup_all(), by Florian Obser.
- Fix #4043: make test fails due to v6 presentation issue in macOS.
- Fix unable to resolve after new WLAN connection, due to auth-zone
  failing with a forwarder set.  Now, auth-zone is only used for
  answers (not referrals) when a forwarder is set.
- Combine write of tcp length and tcp query for dns over tls.
- nitpick fixes in example.conf.
- Fix above stub queries for type NS and useless delegation point.
- Fix unbound-control over pipe with openssl 1.1.1, the TLSv1.3
  tls_choose_sigalg routine does not allow the ciphers for the pipe,
  so use TLSv1.2.
- Fix that flush_zone sets prefetch ttl expired, so that with
  serve-expired enabled it'll start prefetching those entries.
- Fix downstream auth zone, only fallback when auth zone fails to
  answer and fallback is enabled.
- Fix for max include depth for authzones.
- Fix memory free on fail for $INCLUDE in authzone.
- Fix that an internal error to look up the wrong rr type for
  auth zone gets stopped, before trying to send there.
- Fix auth zone target lookup iterator.
- Fix auth-zone retry timer to be on schedule with retry timeout,
  with backoff.  Also time a refresh at the zone expiry.
- Fix #658: unbound using TLS in a forwarding configuration does not
  verify the server's certificate (RFC 8310 support).
- For addr with #authname and no @port notation, the default is 853.
- man page documentation for dns-over-tls forward-addr '#' notation.
- removed free from failed parse case.
- Fix #4091: Fix that reload of auth-zone does not merge the zonefile
  with the previous contents.
- Delete auth zone when removed from config.
- makedist uses bz2 for expat code, instead of tar.gz.

  config_set_option.
- auth zone http download stores exact copy of downloaded file,
  including comments in the file.
- Fix sldns parse failure for CDS alternate delete syntax empty hex.
- Attempt for auth zone fix; add of callback in mesh gets from
  callback does not skip callback of result.
- Fix cname classification with qname minimisation enabled.
- Fix contrib/fastrpz.patch for this release.
- Fix auth https for libev.
- Fix memory leak when caching wildcard records for aggressive NSEC use
- Fix for crash in daemon_cleanup with dnstap during reload,
  from Saksham Manchanda.
- Also that for dnscrypt.

Log message:
Upgrade unbound to version 1.7.0.

Pkgsrc changes:
 * Add libunbound.pc to PLIST.

Upstream changes:

Features
- auth-zone provides a way to configure RFC7706 from unbound.conf,
  eg. with auth-zone: name: "." for-downstream: no for-upstream: yes
  fallback-enabled: yes and masters or a zonefile with data.
- Aggressive use of NSEC implementation. Use cached NSEC records to
  generate NXDOMAIN, NODATA and positive wildcard answers.
- Accept tls-upstream in unbound.conf, the ssl-upstream keyword is
  also recognized and means the same.  Also for tls-port,
  tls-service-key, tls-service-pem, stub-tls-upstream and
  forward-tls-upstream.
- [dnscrypt] introduce dnscrypt-provider-cert-rotated option,
  from Manu Bretelle.
  This option allows handling multiple cert/key pairs while only
  distributing some of them.
  In order to reliably match a client magic with a given key without
  strong assumption as to how those were generated, we need both key and
  cert. Likewise, in order to know which ES version should be used.
  On the other hand, when rotating a cert, it can be desirable to only
  serve the new cert but still be able to handle clients that are still
  using the old certs's public key.
  The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not
  publish the cert as part of the DNS's provider_name's TXT answer.
- Update B root ipv4 address.
- make ip-transparent option work on OpenBSD.
- Fix #2801: Install libunbound.pc.
- ltrace.conf file for libunbound in contrib.
- Fix #3598: Fix swig build issue on rhel6 based system.
  configure --disable-swig-version-check stops the swig version check.

Bug Fixes
- Fix #1749: With harden-referral-path: performance drops, due to
  circular dependency in NS and DS lookups.
- [dnscrypt] prevent dnscrypt-secret-key, dnscrypt-provider-cert
  duplicates
- Better documentation for cache-max-negative-ttl.
- Fixed libunbound manual typo.
- Fix #1949: [dnscrypt] make provider name mismatch more obvious.
- Fix #2031: Double included headers
- Document that errno is left informative on libunbound config read
  fail.
- iana port update.
- Fix #1913: ub_ctx_config is under circumstances thread-safe.
- Fix #2362: TLS1.3/openssl-1.1.1 not working.
- Fix #2034 - Autoconf and -flto.
- Fix #2141 - for libsodium detect lack of entropy in chroot, print
  a message and exit.
- Fix #2492: Documentation libunbound.
- Fix #2882: Unbound behaviour changes (wrong) when domain-insecure is
  set for stub zone.  It no longer searches for DNSSEC information.
- Fix #3299 - forward CNAME daisy chain is not working
- Fix link failure on OmniOS.
- Check whether --with-libunbound-only is set when using --with-nettle
  or --with-nss.
- Fix qname-minimisation documentation (A QTYPE, not NS)
- Fix that DS queries with referral replies are answered straight
  away, without a repeat query picking the DS from cache.
  The correct reply should have been an answer, the reply is fixed
  by the scrubber to have the answer in the answer section.
- Fix that expiration date checks don't fail with clang -O2.
- Fix queries being leaked above stub when refetching glue.
- Copy query and correctly set flags on REFUSED answers when cache
  snooping is not allowed.
- make depend: code dependencies updated in Makefile.
- Fix #3397: Fix that cachedb could return a partial CNAME chain.
- Fix #3397: Fix that when the cache contains an unsigned DNAME in
  the middle of a cname chain, a result without the DNAME could
  be returned.
