5bea29b01c - For #1110: Test for fallthrough attribute in configure and add 
fallthrough attribute annotations.
 2024-07-23 09:47:42 +02:00
Richard Barnes

Make fallthrough explicit for libworker.c 
The code currently doesn't compile with LLVM's `-Wimplicit-fallthrough` flag, but the attribute works for both GCC (>=7) and LLVM.

75f3fbdd65 Downstream DNS Cookies a la RFC7873 and RFC9018 
Create server cookies for clients that send client cookies.
Needs to be turned on in the config file with:

	answer-cookie: yes

A cookie-secret can be configured for anycast setups.
Also adds an access control list that will allow queries with
either a valid cookie or over a stateful transport.

Allow configuration of TCP timeout while waiting for response 
This allows us to configure how long Unbound will wait for a response
on a TCP connection.

75875d4d1c
Allow configuration of persistent TCP connections 
Added 2 new options to configure previously hardcoded
values: max-reuse-tcp-queries and tcp-reuse-timeout. These
allow fine-grained control over how unbound uses persistent
TCP connections to authority servers.

Serve stale (#159) 
- 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.

0171d06aa2 - #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.

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.
