libcares: updated to 1.34.3

c-ares version 1.34.3 - November 9 2024

This is a bugfix release.

Changes:

  provenance as per [SLSA3](https://slsa.dev/).

Bugfixes:
* Some upstream servers are non-compliant with EDNS options, resend queries
  without EDNS.
* Android: <=7 needs sys/system_properties.h
* Android: CMake needs `-D_GNU_SOURCE` and others.
* TSAN warns on missing lock, but lock isn't actually necessary.
* `ares_getaddrinfo()` for `AF_UNSPEC` should retry IPv4 if only IPv6 is
  received.
* `ares_send()` shouldn't return `ARES_EBADRESP`, its `ARES_EBADQUERY`.
* Fix typos in man pages.

c-ares version 1.28.1 - Mar 30 2024

This release contains a fix for a single significant regression introduced in \ 
c-ares 1.28.0.

    ares_search() and ares_getaddrinfo() resolution fails if no search domains \ 
are specified. Issue #737

c-ares version 1.28.0 - Mar 29 2024

This is a feature and bugfix release.

Features:

    Emit warnings when deprecated c-ares functions are used. This can be \ 
disabled by passing a compiler definition of CARES_NO_DEPRECATED. PR #732
    Add function ares_search_dnsrec() to search for records using the new DNS \ 
record data structures. PR #719
    Rework internals to pass around ares_dns_record_t instead of binary data, \ 
this introduces new public functions of ares_query_dnsrec() and \ 
ares_send_dnsrec(). PR #730

Changes:

    tests: when performing simulated queries, reduce timeouts to make tests run \ 
faster
    Replace configuration file parsers with memory-safe parser. PR #725
    Remove acountry completely, the manpage might still get installed otherwise. \ 
Issue #718

Bugfixes:

    CMake: don't overwrite global required libraries/definitions/includes which \ 
could cause build errors for projects chain building c-ares. Issue #729
    On some platforms, netinet6/in6.h is not included by netinet/in.h and needs \ 
to be included separately. PR #728
    Fix a potential memory leak in ares_init(). Issue #724
    Some platforms don't have the isascii() function. Implement as a macro. PR #721

Log message:
libcares: update to 1.27.0.

This is a security, feature, and bugfix release.

Security:

    Moderate. CVE-2024-25629. Reading malformatted /etc/resolv.conf,

    crash. GHSA-mg26-v6qh-x48q

Features:

    New function ares_queue_active_queries() to retrieve number of
    in-flight queries. PR #712

    in-flight queries to reach zero. PR #710
    New ARES_FLAG_NO_DEFLT_SVR for ares_init_options() to return
    a failure if no DNS servers can be found rather than attempting
    to use 127.0.0.1. This also introduces a new ares status code
    of ARES_ENOSERVER. PR #713

- tests: replace google DNS with CloudFlare for reverse lookups as google's \ 
servers stopped responding properly

- OSSFuzz: it assumes autotools builds a static library by default, which means \ 
the old autotools must have done that even though there were comments saying it \ 
wasn't.  Disable static by default on Windows however since it can't build both \ 
simultaneously.

- autotools: update logic for building tests to provide more feedback

- set winver consistently across build systems

  Autotools: rework to simplify and fix recent issues (#674)

  Completely rework the autotools build system, issues have cropped up due to \ 
the complexity and could cause issues on even semi-modern Linux systems (Ubuntu \ 
20.04 for example).

  Changes include:

  Remove all curl/xc/cares m4 helper files, they go overboard on detections of \ 
functions and datatypes. Go back to more plain autoconf macros as they've come a \ 
long way over the years.
  Use known systems and heuristics to determine datatypes for functions like \ 
send() and recv(), rather than the error prone detection which required \ 
thousands of permutations and might still get it wrong.
  Remove unneeded configure arguments like --enable-debug or --enable-optimize, \ 
its more common for people to simply pass their own CFLAGS on the command line.
  Only require CARES_STATICLIB definition on Windows static builds, its not \ 
necessary ever for other systems, even when hiding non-public symbols.
  Remove some function and definition detections that were never used in c-ares
  The test framework is now embedded into the toplevel configure system, there \ 
was no need to chain build the test system as it is never built externally to \ 
c-ares.
  As a side-effect of the changes, a configure run completes in about 25% of the \ 
original time.

  This has been tested on various Linux distributions (of varying age), FreeBSD, \ 
MacOS, Windows (via MSYS2 with Mingw), and Solaris10/11 (by @dfandrich), AIX 7.3 \ 
(by @dfandrich). It is not unlikely that this may have broken more esoteric or \ 
legacy systems, and we'll likely need to be ready to accept bug reports and \ 
patches, but it has removed over 10k lines of build system code. It is very \ 
likely any issues that crop up will add far fewer lines of code to fix such \ 
systems.

  Old MacOS SDKs require you include sys/socket.h before net/if.h (#673)

  Old MacOS SDKs (like 10.8) require you include `sys/socket.h` before you \ 
include `net/if.h` as reported by MacPorts.  Using a new SDK but with setting \ 
the macos target version does not have the same issue.

- clang-format

- ares_strsplit() rewrite as wrapper around ares__buf_split()

  We want to limit as much as possible any hand written parsers.
  ares__buf_split() uses the new memory-safe parsing routines.  This
  adds a couple of additional flags to remove duplicates which the
  existing split code did.

- clang-format

- Connection failure should increment server failure count first

  In order to be sure a different server is chosen on the next query,
  a read error should result in the failure count being updated
  first before requeing the request to a different server.

  CI: Add Alpine Linux and old Ubuntu (#667)

  Alpine linux doesn't use glibc but instead musl c, so provides a good \ 
alternative test bed. We are also adding the oldest non-EOL ubuntu version so we \ 
can test against older linux variants to prevent surprises.

  This patch also migrates more tests to use cmake and ninja in order to reduce \ 
overall build times as we seem to run out of credits on Cirrus-CI pretty \ 
quickly.

  Use SOCK_DNS extension on socket on OpenBSD (#659)

  This patch added the `SOCK_DNS` flag when running on OpenBSD. Allowing a \ 
reduced set of `pledge(2)` promises. Before this patch. The "stdio rpath \ 
inet" promises must be used in order to resolve any records. After the \ 
patch inet can be replaced with dns which only allows communication on \ 
destination port 53, instead of on all ports.

  Side note: I checked the OpenBSD kernel source code. Even though the socket \ 
document says the DNS port (typically 53)., The OpenBSD 7.4 kernel only allows \ 
53.
