- Merge PR #164: Framestreams, this branch implements dnstap
unidirectional connectivity in unbound. This has a number of
new features.

The dependency on libfstrm is removed. The fstrm protocol code
resides in dnstap/dnstap_fstrm.h and dnstap/dnstap_fstrm.c. This
contains a brief definition of what unbound needs.

The make unbound-dnstap-socket builds a debug tool,
unbound-dnstap-socket. It can listen, accept multiple DNSTAP
streams and print information. Commandline options control it.

Unbound can reconnect if the unix domain socket file socket is
closed. This uses exponential backoff after which it uses a
one second timer to throttle cpu down. There is also support
to use TCP and TLS for connecting to the log server. There
are new config options to turn them on, in the dnstap section
in the man page and example config file. dnstap-ip with IP
address of server for TCP or TLS use. dnstap-tls to turn
on TLS. And dnstap-tls-server-name, dnstap-tls-cert-bundle,
dnstap-tls-client-key-file and dnstap-tls-client-cert-file
to configure the certificates for server authentication and
client authentication, or leave at "" to not use that.

17 September 2018: Wouter
- Fix compile on Mac for unbound, provide explicit_bzero when libc

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.

- nicer bio free code in unbound-anchor.
- annotate exit functions with noreturn in unbound-control.

11 September 2018: Wouter

local-zones defined outside of views.

28 August 2018: Ralph
- Disable minimal-responses in ipsecmod unit tests.
- Added serve-expired-ttl and serve-expired-ttl-reset options.

27 August 2018: Wouter
- 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.
- next release is called 1.8.0.
- Fix lintflags for lint on FreeBSD.

22 August 2018: George
- #4140: Expose repinfo (comm_reply) to the inplace_callbacks. This

point when the callback is called before the mesh state (modules).
Changes to C and Python's inplace_callback signatures were also
necessary.

21 August 2018: Wouter

enabled.

17 August 2018: Ralph
- Fix classification for QTYPE=CNAME queries when QNAME minimisation is
enabled.

17 August 2018: Wouter
- 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.
- print servfail info to log as error.
- added more servfail printout statements, to the iterator.
- log-servfail: yes prints log lines that say why queries are
returning SERVFAIL to clients.

not compiled in the name of the wrong module.

caching for the contents of that stub or forward, for when you
want immediate changes visible, from Bjoern A. Zeeb.

7 August 2018: Ralph
- Make capsforid fallback QNAME minimisation aware.

7 August 2018: Wouter

about missing privileges during startup). Add 'AF_INET6' to
'RestrictAddressFamilies' (without it IPV6 can't work). From
Guido Shanahan.
- Patch to implement tcp-connection-limit from Jim Hague (Sinodun).
This limits the number of simultaneous TCP client connections
from a nominated netblock.
- make depend, yacc, lex, doc, headers. And log the limit exceeded
message only on high verbosity, so as to not spam the logs when
it is busy.

6 August 2018: Wouter
- Fix for #4136: Fix to unconditionally call destroy in daemon.c.

3 August 2018: George
- 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.
- Tidy pylib tests.

3 August 2018: Wouter
- Revert previous change for #4136: because it introduces build
problems.
- New fix for #4136: This one ignores lex without without
yylex_destroy.

- 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.
- From Wouter: make depend, the dependencies in the patches did not
apply cleanly. Also remade yacc and lex.
- Fix mesh.c incompatible pointer pass.
- Please doxygen so it passes.
- Fix #4139: Fix unbound-host leaks memory on ANY.

Date: 15 Dec, 2016
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, 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).

Fix failure to build on arm64 with no sbrk.
Set OpenSSL security level to 0 when using aNULL ciphers.

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().

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.
