for downstream users. Default is no. The option
is disable-edns-do: no

17 August 2023: Wouter
- Merge PR #762: Downstream DNS Server Cookies a la RFC7873 and
RFC9018. Create server cookies for clients that send client cookies.
This needs to be explicitly turned on in the config file with:
`answer-cookie: yes`. A `cookie-secret:` can be configured for
anycast setups. Without one, a random cookie secret is generated.
The acl option `allow_cookie` allows queries with either a valid
cookie or over a stateful transport. The statistics output has
`queries_cookie_valid` and `queries_cookie_client` and
`queries_cookie_invalid` information. The `ip\-ratelimit\-cookie:`
value determines a rate limit for queries with cookies, if desired.
- Fix regional_alloc_init for potential unaligned source of the copy.

- 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.

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).
Bug Fixes

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().
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.

- 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.

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 #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.

patch from Dag-Erling Smorgrav that removes code that relies on sbrk().

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 #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.
