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.

- Set max-udp-size default to 1232. This is the same default value as
the default value for edns-buffer-size. It restricts client edns

resolvers. The new choice, down from 4096 means it is harder to get
large responses from Unbound. Thanks to Xiang Li, from NISL Lab,
Tsinghua University.

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).
Bug Fixes
Fix #836: unbound could echo back EDNS options in an error response.
Fix #838: 1.5.10 cannot be built on Solaris, undefined PATH_MAX.
Fix #839: Memory grows unexpectedly with large RPZ files.
Fix #840: infinite loop in unbound_munin_ plugin on unowned lockfile.
Fix #841: big local-zone's make it consume large amounts of memory.
Fix dnstap relaying "random" messages instead of resolver/forwarder responses, from Nikolay Edigaryev.
Fix Nits for 1.5.10 reported by Dag-Erling Smorgrav.
Fix #1117: spelling errors, from Robert Edmonds.

g.root-servers.net has AAAA address.
Fix #1134: unbound-control set_option -- val-override-date: -1 works 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, from Pavel Odintsov.
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, by Andreas Schulze

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).

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).

Ported tests for local_cname unit test to testbound framework.
g.root-servers.net has AAAA address.

Patch for server.num.zero_ttl stats for count of expired replies, from Pavel Odintsov.
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, by Andreas Schulze
Fix #1170: document that 'inform' local-zone uses local-data.
Fix #1173: differ local-zone type deny from unset tag_actions element.

TCP Fast open patch from Sara Dickinson.
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.
