- 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`).
- Fixed stats when replying with cached, cname-aliased records.
- Added missing default values for redis cachedb backend.
This adds the possibility to properly register inplace callbacks in the
dynamic library module. It works by creating a wrapper procedure that
is available to the dynamic library and will call the given callback
through a whitelisted callback function.
The dynamic library example has already been improved to include
comments and some simple examples on allocating and deallocating memory
and registering callbacks.
add sockaddr_storage getters, add support for query callbacks,
allow raw address access via comm_reply and update API documentation.

- Limit ECS scope returned to client to the scope used for caching.
- Make lint like previous #4154 fix.

- (de)register inplace callbacks for module id
- No unbound-control set_option for ECS options
- Deprecated client-subnet-opcode config option
- Introduced client-subnet-always-forward config option
- Changed max-client-subnet-ipv6 default to 56 (as in RFC)
- Removed extern ECS config options
- module_restart_next now calls clear on all following modules
- Also create ECS module qstate on module_event_pass event

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.

after parse use edns_opt_find(edns.opt_list, LDNS_EDNS_NSID),
to insert use edns_opt_append(edns, region, code, len, bindata) on
the opt_list passed to send_query, or in edns_opt_inplace_reply.

Initial commit of the patch from the FreeBSD base (with its fixes).
This adds a module (for module-config in unbound.conf) dns64 that
performs DNS64 processing, see README.DNS64.

fixes from FreeBSD's copy of Unbound, he notes:
Generate unbound-control-setup.sh at build time so it respects
prefix and sysconfdir from the configure script. Also fix the
umask to match the comment, and the comment to match the umask.
Add const and static where needed. Use unions instead of
playing pointer poker. Move declarations that are needed in
multiple source files into a shared header. Move sldns_bgetc()
from parse.c to buffer.c where it belongs. Introduce a new
header file, worker.h, which declares the callbacks that
all workers must define. Remove those declarations from
libworker.h. Include the correct headers in the correct places.
Fix a few dummy callbacks that don't match their prototype.
Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK.
Remove a useless printf which breaks reproducible builds.
Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
no longer used. Add unbound-control-setup.sh to the list of
generated files.

the UDP reply has timed out. Keeps the port open, only accepts
the correct reply. This correct reply is not used, but the port
is open so that no port-denied ICMPs are generated.

contains low-level library calls, that use libevent's event_base
and an ldns_buffer for the wire return packet to perform async
resolution in the client's eventloop.
