Pkgsrc changes:
* none, other than checksums.
Upstream changes:
This release has bug fixes for crashes that happened on heavy network
usage. The default for the aggressive-nsec option has changed, it is now
enabled.
The ratelimit logic had to be reworked for the crash fixes. As a result,
there are new options to control the behaviour of ratelimiting.
The ratelimit-backoff and ip-ratelimit-backoff options can be used to
control how severe the backoff is when the ratelimit is exceeded.
The rpz-signal-nxdomain-ra option can be used to unset the RA flag, for
NXDOMAIN answers from RPZ. That is used by some clients to detect that
the domain is externally blocked. The RPZ option for-downstream can be
used like for auth zones, this allows the RPZ zone information to be
queried. That can be useful for monitoring scripts.
Features
- Fix#596: unset the RA bit when a query is blocked by an unbound
RPZ nxdomain reply. The option rpz-signal-nxdomain-ra allows to
signal that a domain is externally blocked to clients when it
is blocked with NXDOMAIN by unsetting RA.
- Add rpz: for-downstream: yesno option, where the RPZ zone is
authoritatively answered for, so the RPZ zone contents can be
checked with DNS queries directed at the RPZ zone.
- Merge PR #616: Update ratelimit logic. It also introduces
ratelimit-backoff and ip-ratelimit-backoff configuration options.
- Change aggressive-nsec default to yes.

Pkgsrc changes:
* none, other than checksums.
Upstream changes:
This release contains a number of bug fixes. There is added support
for the EDNS Padding option (RFC7830 and RFC8467), and the EDNS NSID
option (RFC 5001). Unbound control has added commands to enable and
disable rpz processing. Reply callbacks have a start time passed to
them that can be used to calculate time, these are callbacks for
response processing. With the option serve-original-ttl the TTL served
in responses is the original, not counted down, value, for when in
front of authority service.
Features
- Merge PR #375 by fhriley: Add rpz_enable and rpz_disable commands
to unbound-control.
- Merge PR #391 from fhriley: Add start_time to reply callbacks so
modules can compute the response time.

Pkgsrc changes:
* none, other than checksums.
Upstream changes:
This version has fixes to connect for UDP sockets, slowing down
potential ICMP side channel leakage. The fix can be controlled with the
option udp-connect: yes, it is enabled by default.
Additionally CVE-2020-28935 is fixed, this solves a problem where the
pidfile is altered by a symlink, and fails if a symlink is encountered.
See https://nlnetlabs.nl/downloads/unbound/CVE-2020-28935.txt for more
information.
New features are upstream TCP and TLS query reuse, where a channel is
reused for several queries. And http-notls-downstream: yesno for
unencrypted DoH, useful for back end support servers. The option
infra-keep-probing can be used to probe hosts that are down more
frequently.
The options edns-client-string and edns-client-string-opcode can be used
to add an EDNS option with the specified string in queries towards
servers, with the servers specified by IP address. It replaces the
edns-client-tag option.
The released version equals the 1.13.0rc4 with an added fix for stream
reuse and tcp fast open.
Features
- Pass the comm_reply information to the inplace_cb_reply* functions
during the mesh state and update the documentation on that.
- Fix#330: [Feature request] Add unencrypted DNS over HTTPS support.
This adds the option http-notls-downstream: yesno to change that,
and the dohclient test code has the -n option.
- Merge PR #228 : infra-keep-probing option to probe hosts that are
down. Add infra-keep-probing: yes option. Hosts that are down are
probed more frequently.
With the option turned on, it probes about every 120 seconds,
eventually after exponential backoff, and that keeps that way. If
traffic keeps up for the domain. It probes with one at a time, eg.
one query is allowed to probe, other queries within that 120 second
interval are turned away.
- Merge PR #313 from Ralph Dolmans: Replace edns-client-tag with
edns-client-string option.
- Merge PR #283 : Stream reuse. This implements upstream stream

Pkgsrc changes:
* Add option for doh (DNS-over-HTTPS), default enabled.
Upstream changes:
This release contains the DNS Flag Day 2020 changes. This sets the
default EDNS buffer size to 1232, that should reduce fragmentation.
https://dnsflagday.net/2020/
There is inclusive language in the configuration. There is caps-exempt,
ipsecmod-allow and primary server options for auth-zones. The older
terms are accepted to keep configuration working.
DNS-over-HTTPS is supported in this release. The DoH is enabled when
Unbound is compiled with the nghttp2 library, with configure
--with-libnghttp2. Then have an interface on the https port, that can
be configured with the https-port option. Also have a cert and key
available with the tls-service-key and tls-service-pem options. Further
settings can be configured for the http-endpoint, http-max-streams,
http-query-buffer-size, http-response-buffer-size and http-nodelay
options. The max streams sets the maximum concurrent streams, the
buffer size options the number of bytes in buffers, and the nodelay
option can turn on TCP_NODELAY for DNS-over-HTTPS service. In the
statistics the memory used is reported in mem.http.query_buffer and
mem.http.response_buffer. The number of queries is reported in
num.query.https, they are also included in the tcp and tls counts
because https uses TLS and TCP.
The DLV options and code to handle DLV lookups have been removed from
the code base. The DLV repository is empty nowadays, it has been
decommissioned.
There is a new feature where it is possible to use interface names to
bind to the IP addresses on that interface. It pulls in the addresses
at the start of the server, if the addresses change, use the existing
freebind and other socket options to register for addresses before they
appear, or the interface-automatic option that copies them from queries
to answers with ancillary data.
There is a new option for the edns-tag draft specification. It can be
enabled if you need the tentative implementation to add those tags to
outgoing messages.
Features
- DNS Flag Day 2020: change edns-buffer-size default to 1232.
- Merge PR #255: DNS-over-HTTPS support.
- Use inclusive language in configuration
- Merge PR #284 and Fix#246: Remove DLV entirely from Unbound.
The DLV has been decommisioned and in unbound 1.5.4, in 2015, there
was advise to stop using it. The current code base does not contain
DLV code any more. The use of dlv options displays a warning.
- Similar to NSD PR#113, implement that interface names can be used,
eg. something like interface: eth0 is resolved at server start and
uses the IP addresses for that named interface.
- Merge PR #272: Add EDNS client tag functionality.
- Add edns-client-tag-opcode option

Upstream changes:
This release fixes CVE-2020-12662 and CVE-2020-12663.
Bug Fixes:
- CVE-2020-12662 Unbound can be tricked into amplifying an incoming
query into a large number of queries directed to a target.
- CVE-2020-12663 Malformed answers from upstream name servers can be
used to make Unbound unresponsive.
Pkgsrc changes:
* Adjust line numbers in patch.
Upstream changes:
The 1.10.0 release has RPZ support and serve stale functionality
according to draft draft-ietf-dnsop-serve-stale-10. And a number of
other, smaller, features, and bug fixes.
The DNS Response Policy Zones (RPZ) functionality makes it possible
to express DNS response policies in a DNS zone. These zones can
be loaded from file or transferred over DNS zone transfers or
HTTP. The RPZ functionality in Unbound is implemented as specified in
draft-vixie-dnsop-dns-rpz-00. Only the QNAME and Response IP Address
triggers are supported. The supported RPZ actions are: NXDOMAIN, NODATA,
PASSTHRU, DROP and Local Data.
Enabling the respip module using `module-config` is required to use
RPZ. Each RPZ zone can be configured using the `rpz` clause. RPZ clauses
are applied in order of configuration. Unbound can get the data from
zone transfer, a zonefile or https url, and more options are documented
in the man page. A minimal RPZ configuration that will transfer the
RPZ zone using AXFR and IXFR can look like:
server:
module-config: "respip validator iterator"
rpz:
name: "rpz.example.com" # name of the policy zone
master: 192.0.2.0 # address of the name server to transfer from
The serve-stale functionality as described in
draft-ietf-dnsop-serve-stale-10 is now supported in unbound.
This allows unbound to first try and resolve a domain name before
replying with expired data from cache. This differs from unbound's
initial serve-expired behavior which attempts to reply with expired
entries from cache without waiting for the actual resolution to finish.
Both behaviors are available and can be configured with the various
serve-expired-* configuration options. serve-expired-client-timeout is
the option that enables one or the other.
The DSA algorithms have been disabled by default, this is because of
RFC 8624.
There is a crash fix in the parse of text of type WKS, reported by
X41 D-Sec.
In addition, neg and key caches can be shared with multiple
libunbound contexts, a change that assists unwind. The
contrib/unbound_portable.service provides a systemd start file for a
portable setup. The configure --with-libbsd option allows the use
of the bsd compatibility library so that it can use the arc4random
from it. The stats in contrib/unbound_munin_ have num.query.tls and
num.query.tls.resume added to them. For unbound-control the command
view_local_datas_remove is added that removes data from a view.
Features:
- Merge RPZ support into master. Only QNAME and Response IP triggers are
supported.
- Added serve-stale functionality as described in
draft-ietf-dnsop-serve-stale-10. `serve-expired-*` options can be used
to configure the behavior.
- Updated cachedb to honor `serve-expired-ttl`; Fixes#107.
- Renamed statistic `num.zero_ttl` to `num.expired` as expired replies
come with a configurable TTL value (`serve-expired-reply-ttl`).
- Merge #135 from Florian Obser: Use passed in neg and key cache
if non-NULL.
- Fix#153: Disable validation for DSA algorithms. RFC 8624 compliance.

Pkgsrc changes:
* Remove now integrated patch.
Upstream changes:
This release contains a number of security related fixes, contributed by
X41 D-Sec. They have conducted a security audit of Unbound, funded by
OSTIF. The previous CVEs fixed in 1.9.4 and 1.9.5 were the most
important ones, less important fixes and side findings for more robust
code have been included in this release, alongside a normal number of
bug fixes.
The sort order for included config snippets is now ascending by name, it
previously was reversed due to an oversight. Most config snippets do
not depend on the order as they add a stub or forward zone or some
server: section config entries.
Features:
- The unbound.conf includes are sorted ascending, for include
statements with a '*' from glob.
- drop-tld.diff in contrib/ : adds option drop-tld: yesno that drops 2 label
queries, to stop random floods. Apply with
patch -p1 < contrib/drop-tld.diff and compile.
From Saksham Manchanda (Secure64). Please note that we think this
will drop DNSKEY and DS lookups for tlds and hence break DNSSEC
lookups for downstream clients.
- Add new configure option `--enable-fully-static` to enable full static
build if requested; in relation to #91.
- Add make distclean that removes everything configure produced,
and make maintainer-clean that removes bison and flex output.
- unbound-fuzzers.tar.bz2 in contrib/ : three programs for fuzzing, that
are 1:1 replacements for unbound-fuzzme.c that gets created after applying
the contrib/unbound-fuzzme.patch. They are contributed by
Eric Sesterhenn from X41 D-Sec.
Bug Fixes:
- Fix that pkg-config is setup before --enable-systemd needs it.
- Fix contrib/fastrpz.patch asprintf return value checks.
- ipset module #28: log that an address is added, when verbosity high.
- ipset: refactor long routine into three smaller ones.
- updated Makefile dependencies.
- squelch DNS over TLS errors 'ssl handshake failed crypto error'
on low verbosity, they show on verbosity 3 (query details), because
there is a high volume and the operator cannot do anything for the
remote failure. Specifically filters the high volume errors.
- Fix#71: fix openssl error squelch commit compilation error.
- Fix#72: configure --with-syslog-facility=LOCAL0-7 with default
LOG_DAEMON (as before) can set the syslog facility that the server

Bug Fixes:
- Fix CVE-2019-16866. An error in parsing NOTIFY queries may cause
unbound to continue processing malformed queries and may ultimately
result in a pointer de-reference in un-initialized memory, causing
a crash of unbound.
Upstream changes:
This release has a number of bug fixes. Added is the ipset module, that
helps add ip-addresses that are looked up in a domain to a firewall
ip-address filter. Also, the python module has restart next, per-query
data and multiple instance support. The unbound -V option has been
added and it prints the build config.
Features:
- PR #28: IPSet module, by Kevin Chou. Created a module to support
the ipset that could add the domain's ip to a list easily.
Needs libmnl, and --enable-ipset and config it, doc/README.ipset.md.
- Merge PR #6: Python module: support multiple instances
- Merge PR #5: Python module: define constant MODULE_RESTART_NEXT
- Merge PR #4: Python module: assign something useful to the
per-query data store 'qdata'
- Introduce `-V` option to print the version number and build options.
Previously reported build options like linked libs and linked modules
are now moved from `-h` to `-V` as well for consistency.
- PACKAGE_BUGREPORT now also includes link to GitHub issues.
Bug Fixes:
- Fix#39: In libunbound, leftover logfile is close()d unpredictably.
- Fix for #24: Fix abort due to scan of auth zone masters using old
address from previous scan.
- Fix to omit RRSIGs from addition to the ipset.
- Fix to make unbound-control with ipset, remove unused variable,
use unsigned type because of comparison, and assign null instead
of compare with it. Remade lex and yacc output.
- make depend
- Added documentation to the ipset files (for doxygen output).
- Fix python dict reference and double free in config.
- Fix memleak in unit test, reported from the clang 8.0 static analyzer.
- For #45, check that 127.0.0.1 and ::1 are not used in unbound.conf
when do-not-query-localhost is turned on, or at default on,
unbound-checkconf prints a warning if it is found in forward-addr or
stub-addr statements.
- Fix for possible assertion failure when answering respip CNAME from
cache.
- Fix in respip addrtree selection. Absence of addr_tree_init_parents()
call made it impossible to go up the tree when the matching netmask is
too specific.
- Fix#48: Unbound returns additional records on NODATA response,
if minimal-responses is enabled, also the additional for negative
responses is removed.
- Fix#49: Set no renegotiation on the SSL context to stop client
session renegotiation.
- Fix question section mismatch in local zone redirect.
- Add verbose log message when auth zone file is written, at level 4.
- Add hex print of trust anchor pointer to trust anchor file temp
name to make it unique, for libunbound created multiple contexts.
- For #52#53, second context does not close logfile override.
- Fix#52#53, fix for example fail program.
- Fix to return after failed auth zone http chunk write.
- Fix to remove unused test for task_probe existance.
- Fix to timeval_add for remaining second in microseconds.
- Check repinfo in worker_handle_request, if null, drop it.
- Generate configlexer with newer flex.
- Fix warning for unused variable for compilation without systemd.
- Fix#59, when compiled with systemd support check that we can properly
communicate with systemd through the `NOTIFY_SOCKET`.
- iana portlist updated.
- Fix autotrust temp file uniqueness windows compile.
- avoid warning about upcast on 32bit systems for autotrust.
- escape commandline contents for -V.
- Fix character buffer size in ub_ctx_hosts.
- Option -V prints if TCP fastopen is available.
- Fix unittest valgrind false positive uninitialised value report,
where if gcc 9.1.1 uses -O2 (but not -O1) then valgrind 3.15.0
issues an uninitialised value for the token buffer at the str2wire.c
rrinternal_get_owner() strcmp with the '@' value. Rewritten to use
straight character comparisons removes the false positive. Also
valgrinds --expensive-definedness-checks=yes can stop this false
positive.
- Please doxygen's parser for "@" occurrence in doxygen comment.
- Fixup contrib/fastrpz.patch
- Remove warning about unknown cast-function-type warning pragma.
- Document limitation of pidfile removal outside of chroot directory.
- Fix log_dns_msg to log irrespective of minimal responses config.

the file contains detailed documentation.
- travis build file.
- PR #16: XoT support, AXFR over TLS, turn it on with

* Sometimes qname-minimisation needs to be (temporarily) reverted.
* DNS-over-TLS would interact with qname-minimisation and would erroneously
echo back the query buffer instead of the answer.
Bump PKGREVISION.
Upstream changes:
This release contains the DNS Flag Day changes for Unbound. See the
reference here, https://dnsflagday.net/ . Or this presentation:
https://indico.dns-oarc.net/event/29/contributions/662/attachments/634/1063/EDNS_Flag_Day_-_OARC29.pdf
. The EDNS timeouts are not used to fallback to nonEDNS queries.
Features

- 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,

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

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.

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.

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

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).

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.

=============
Features:
---------
- 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.
- 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.
- 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).
- g.root-servers.net has AAAA address.

immediately to ignore datetime, or back to 0 to enable it again. The --
is to ignore the '-1' as an option flag.
- Patch for server.num.zero_ttl stats for count of expired replies.
- 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.
- QNAME minimisation uses QTYPE=A, therefore always check cache for this
type in harden-below-nxdomain functionality.
- Added unit test for QNAME minimisation + harden below nxdomain synergy.
- Fix that with openssl 1.1 control-use-cert: no uses less cpu, by using
no encryption over the unix socket.
- hyphen as minus fix.
- Fix#1170: document that 'inform' local-zone uses local-data.
- Fix#1173: differ local-zone type deny from unset tag_actions element.
- Add DSA support for OpenSSL 1.1.0
- Fix remote control without cert for LibreSSL
- Fix downcast warnings from visual studio in sldns code
- Create a pkg-config file for libunbound in contrib.
- TCP Fast open.
- Finegrained localzone control with define-tag, access-control-tag,
access-control-tag-action, access-control-tag-data, local-zone-tag, and
local-zone-override. And added types always_transparent, always_refuse,
always_nxdomain with that.
- If more than half of tcp connections are in use, a shorter timeout
is used (200 msec, vs 2 minutes) to pressure tcp for new connects.
- [bugzilla: 787 ] Fix#787: outgoing-interface netblock/64 ipv6
option to use linux freebind to use 64bits of entropy for every query
with random local part.
- For #787: prefer-ip6 option for unbound.conf prefers to send
upstream queries to ipv6 servers.
- Add default root hints for IPv6 E.ROOT-SERVERS.NET, 2001:500:a8::e.
- keep debug symbols in windows build.
