unbound: updated to 1.13.2

1.13.2

Features

Merge 317: ZONEMD Zone Verification, with RFC 8976 support. ZONEMD records are checked for zones loaded as auth-zone, with DNSSEC if available. There is an added option zonemd-permissive-mode that makes it log but not fail wrong zones. With zonemd-reject-absence for an auth-zone the presence of a zonemd can be mandated for specific zones.
Fix: Resolve interface names on control-interface too.
Merge 470 from edevil: Allow configuration of persistent TCP connections.
Fix 474: always_null and others inside view.
Add that log-servfail prints an IP address and more information about one of the last failures for that query.
Merge 478: Allow configuration of TCP timeout while waiting for response.
Add ./configure --with-deprecate-rsa-1024 that turns off RSA 1024.
Move the NSEC3 max iterations count in line with the 150 value used by BIND, Knot and PowerDNS. This sets the default value for it in the configuration to 150 for all key sizes.
zonemd-check: yesno option, default no, enables the processing of ZONEMD records for that zone.
Merge 486 by fobster: Make VAL_MAX_RESTART_COUNT configurable.
Merge 491: Add SVCB and HTTPS types and handling according to draft-ietf-dnsop-svcb-https.
Introduce 'http-user-agent:' and 'hide-http-user-agent:' options.

fixes PR pkg/54126

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.
- Fix that unbound-checkconf -f flag works with auto-trust-anchor-file
  for startup scripts to get the full pathname(s) of anchor file(s).
- Print fatal errors about remote control setup before log init,
  so that it is printed to console.
- Use NSEC with longest ce to prove wildcard absence.
- Only use *.ce to prove wildcard absence, no longer names.
- Fix unfreed locks in log and arc4random at exit of unbound.
- Fix lock race condition in dns cache dname synthesis.
- Fix #3451: dnstap not building when you have a separate build dir.
  And removed protoc warning, set dnstap.proto syntax to proto2.
- Added tests with wildcard expanded NSEC records (CVE-2017-15105 test)
- Unit test for auth zone https url download.
- tls-cert-bundle option in unbound.conf enables TLS authentication.
- Fixes for clang static analyzer, the missing ; in
  edns-subnet/addrtree.c after the assert made clang analyzer
  produce a failure to analyze it.
- Fix #3505: Documentation for default local zones references
  wrong RFC.
- Fix #3494: local-zone noview can be used to break out of the view
  to the global local zone contents, for queries for that zone.
- Fix for more maintainable code in localzone.
- more robust cachedump rrset routine.
- Save wildcard RRset from answer with original owner for use in
  aggressive NSEC.

- iana port update.
- Fix #3582: Squelch address already in use log when reuseaddr option
  causes same port to be used twice for tcp connections.
- Reverted fix for #3512, this may not be the best way forward;
  although it could be changed at a later time, to stay similar to
  other implementations.
- Fix for windows compile.
- Fixed contrib/fastrpz.patch, even though this already applied
  cleanly for me, now also for others.
- patch to log creates keytag queries, from A. Schulze.
- patch suggested by Debian lintian: allow to -> allow one to, from
  A. Schulze.
- Attempt to remove warning about trailing whitespace.
- Added documentation for aggressive-nsec: yes.

Remove example rc.d scripts from PLISTs.

These are now handled dynamically if INIT_SYSTEM is set to "rc.d", or
ignored otherwise.

Unbound 1.4.21

Features:

* Implement max-udp-size config option, default 4096 with fix#524 for
  nonEDNS0 queries.
* add unbound-control insecure_add and insecure_remove for the administration
  of negative trust anchors.
* install copy of unbound-control.8 man page for unbound-control-setup.
* code improve for minimal responses, small speed increase.
* max include of 100.000 files (depth and globbed at one time).
  This is to preserve system memory in bug cases, or endless cases.
* unbound.h header file has UNBOUND_VERSION_MAJOR define.
* get_option, set_option, unbound-checkconf -o and libunbound getoption() and
  setoption() support cache-min-ttl and cache-max-ttl. Also log-time-ascii,
  python-script, val-sig-skew-min and val-sig-skew-max. log-time-ascii takes
  effect immediately. The others are mostly useful for libunbound users.
* configure --disable-flto option.
* streamtcp man page.
* Make reverse zones easier by documenting the nodefault statements
  commented-out in the example config file.

Bug Fixes:

* committed libunbound version 4:1:2 for binary API updated in 1.4.20
* Fix for 2038, with time_t instead of uint32_t.
* Fix resolve of names that use a mix of public and private addresses.
* [bugzilla: 492 ] Fix endianness detection, revert to older lookup3.c
  detection and put new detect lines after previous tests, to avoid
  regressions but allow new detections to succeed.
  And add detection for machine/endian.h to it.
* Fix queries leaking up for stubs and forwards, if the configured
  nameservers all fail to answer.
* unbound-anchor review: BIO_write can return 0 successfully if it has
  successfully appended a zero length string.
* Fix so that for a configuration line of include: "*.conf" it is not an
  error if there are no files matching the glob pattern.
* own implementation of compat/snprintf.c.
* [bugzilla: 491 ] pick program name (0th argument) as syslog identity.
* Fixup snprintf return value usage, fixed libunbound_get_option.
* Robust checks on dname validity from rdata for dname compare.
* iana portlist update.
* Fix round-robin doesn't work with some Windows clients.
* [bugzilla: 500 ] use on non-initialised values on socket bind failures.
* [bugzilla: 499 ] use-after-free in out-of-memory handling code.
* Explain bogus and secure flags in libunbound more.
* Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply patch to it
  to not fail when -Werror is also specified, from the autoconf-archives.
* Fixup manpage syntax.
* Fix for const string literals in C++ for libunbound.
* Squelch sendto-permission denied errors when the network is not connected,
  to avoid spamming syslog.
* libunbound documentation on how to avoid openssl race conditions.
* [bugzilla: 512 ] NSS returned arrays out of setup function to be statics.
* [bugzilla: 516 ] dnssec lameness detection for answers that are improper.
* [bugzilla: 519 ] ub_ctx_delete may hang in some scenarios (libunbound).
* [bugzilla: 520 ] Errors found by static analysis

Unbound 1.4.19

Features:

* RFC6725 deprecates RSAMD5: this DNSKEY algorithm is disabled.
  The contrib/patch_rsamd5_enable.diff patch enables RSAMD5 validation
  otherwise it is treated as insecure. The MD5 hash is considered weak for
  some purposes, if you want to sign your zone, then RSASHA256 is an
  uncontested hash.
* unbound-control -q option is quiet
* include: directive in config file accepts wildcards.
  Suggested use: include: "/etc/unbound.d/conf.d/*"

Bug Fixes:

* Fix openssl race condition, initializes openssl locks.
* Improved forward-first and stub-first documentation.
* Fix that enables modules to register twice for the same serviced_query,
  without race conditions or administration issues.
* Fix forward-first option where it sets the RD flag wrongly.
* added manpage links for libunbound calls.
* Add documentation to libunbound for default nonuse of resolv.conf.
* Fix timeouts so that when a server has been offline for a while and is
  probed to see it works, it becomes fully available for server selection again.
* Fallback to 1472 and 1232, one fragment size without headers.
* [bugzilla: 465 ] Nicer comments outgoing-port-avoid.
* chdir to / after chroot call (suggested by Camiel Dobbelaar).
* updated contrib/unbound.spec.
* ignore trusted-keys globs that have no files (from Paul Wouters).
* fix text in unbound-anchor man page.
* fix build of pythonmod in objdir.
* make clean and makerealclean remove generated python and docs.
* Fix validation for responses with both CNAME and wildcard expanded CNAME
  records in answer section.
* [bugzilla: 477 ] Fix unbound-anchor segfault if EDNS is blocked.
* Fix unbound-control forward disables configured stubs below it.
* [bugzilla: 481 ] Fix python example0.
* iana portlist updated.

unbound 1.48:

Features:
* harden-below-nxdomain config option, default off (because very old software
  may be incompatible). We could enable it by default in the future.
  From draft-vixie-dnsext-resimprove-00.
* typetransparent localzone: does not block other RR types.
* so-sndbuf option for very busy servers, a bit like so-rcvbuf.

Bug Fixes:
* Fix so a changed NS RRset does not get moved name stuck on old server,
  for type NS the TTL is not increased.
* Fix prefetch so it does not get stuck on old server for moved names.
* Fix insecure CNAME sequence marked as secure, reported by Bert Hubert.
* faster lruhash get_mem routine.
* [bugzilla: 346 ] remove ITAR scripts from contrib,
  the service is discontinued, use the root.
* Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
* algorithm compromise protection using the algorithms signalled in the DS
  record. Also, trust anchors, DLV, and RFC5011 receive this, and thus,
  if you have multiple algorithms in your trust-anchor-file then it will now
  behave different than before. Also, 5011 rollover for algorithms needs to be
  double-signature until the old algorithm is revoked.
* squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them)
* fix validation in this case: CNAME to nodata for co-hosted opt-in
  NSEC3 insecure delegation, was bogus, fixed to be insecure.
* Fix our 'BDS' license (typo reported by Xavier Belanger).
* [bugzilla: 338 ] print address when socket creation fails.
* Fix storage of EDNS failures in the infra cache.
* silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
* unbound-anchor compiles with openssl 0.9.7.
* Be lenient and accept imgw.pl malformed packet (like BIND).
* the included ldns tarball is updated (to 1.6.8)
* iana portlist updated.

unbound 1.47:

Features:
* unbound-anchor app, unbound requires libexpat (xml parser library).
  It creates or updates a root.key file. Use it before you start the validator
  (e.g. at system boot time).
* dump_infra and flush_infra commands for unbound-control.

Bug Fixes:
* GOST code enabled by default (RFC 5933).
* Configure detects libev-4.00.
* do not synthesize a CNAME message from cache for qtype DS.
* Use central entropy to seed threads.
* Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
* Fix validation failure for parent and child on same server with an insecure
  childzone and a CNAME from parent to child.
* Change of timeout code. No more lost and backoff in blockage. At 12sec timeout
  (and at least 2x lost before) one probe per IP is allowed only. At 120sec,
  the IP is blocked. After 15min, a 120sec entry has a single retry packet.
* no timeout backoff if meanwhile a query succeeded.
* Configure errors if ldns is not found.
* Windows 7 fix for the installer.
* Fix bug where fallback_tcp causes wrong roundtrip and edns observation to be
  noted in cache. Fix bug where EDNSprobe halted exponential backoff if EDNS
  status unknown.
* interface automatic works for some people with ip6 disabled. Therefore the
  error check is removed, so they can use the option.
* Fix TCP so it uses a random outgoing-interface.
* Fix bug when DLV below a trust-anchor that uses NSEC3 optout where the zone
  has a secure delegation hosted on the same server did not verify as secure
  (it was insecure by mistake).
* Fix alloc_reg_release for longer uptime in out of memory conditions.
* [bugzilla: 329 ] in example.conf show correct ipv4 link-local 169.254/16.
* compliance with draft-ietf-dnsop-default-local-zones-14,
  removed reverse ipv6 orchid prefix from builtin list.
* Algorithm rollover operational reality intrudes, for trust-anchor and
  5011-store, if one key matches it's good enough.
* Fix reported validation error in out of memory condition.
* Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
* increased mesh-max-activation from 1000 to 3000 for crazy domains like
  _tcp.slb.com with 262 servers.
* [bugzilla: 327 ] Fix for cannot access stub zones until the root is primed.
* openbsd-lint fixes
* [bugzilla: 321 ] Fix resolution of rs.ripe.net artifacts with 0x20.
  Delegpt structures checked for duplicates always.
  No more nameserver lookups generated when depth is full anyway.
* [bugzilla: 322 ] Fix, configure does not respect CFLAGS on Solaris.
  Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line if use
  sun-cc, but some systems need different flags.
* Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP changes,
  uses m4_bpatsubst now.
* make test (or make check) should be more portable and run the unit test and
  testbound scripts. (make longtest has special requirements).
* More pleasant remote control command parsing.
* Fix name of rrset printed that failed validation.
* Return NXDOMAIN after chain of CNAMEs ends at name-not-found.
* Fix validation in case a trust anchor enters into a zone with
  unsupported algorithms.
* iana portlist updated.
* updated ldns tarball.

Remove @dirrm entries from PLISTs

Update to unbound-1.1.1:
- improve chroot handling
- even stricter validation
- support for blocking DNS rebinding attacks
- DLV support
- bugfixes

The package now uses the normal net/ldns package instead of the local
copy.

Import unbound-1.0.0, a DNS recursor library and daemon from the guys
that brought us NSD.
