Features:
* Add support for IPv6 link-local DNS servers. Nameserver formats
can now accept the 0face suffix, and a new ares_get_servers_csv()
function was added to return servers that can contain the link-local
interface name.
Changes:
* Unbundle GoogleTest for test cases. Package maintainers will now
need torequire GoogleTest (GMock) as a build dependency if
building tests. New GoogleTest versions require C++14 or later.
* Replace nameserver parsing code to use new memory-safe functions.
* Replace the sortlist parser with new memory-safe functions.
* Various warning fixes and dead code removal.
Bugfixes:
* Old Linux versions require POSIX_C_SOURCE or _GNU_SOURCE to
compile with thread safety support
* A non-responsive DNS server that caused timeouts wouldn't
increment thefailure count, this would lead to other servers
not being tried. Regression introduced in 1.22.0
* Some projects that depend on c-ares expect invalid parameter
option valuespassed into ares_init_options() to simply be
ignored. This behavior has been restored
* getrandom() can fail if the kernel doesn't support
the syscall, fall back to another random source
* ares_cancel() when performing ares_gethostbyname() or
ares_getaddrinfo()with AF_UNSPEC, if called after one address
class was returned but before the other address class, it
would return ARES_SUCCESS rather than ARES_ECANCELLED

OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/c-ares?expand=0&rev=57
Features:
Introduce optional (but on by default) thread-safety for the c-ares library. This has no API nor ABI implications.
resolv.conf in modern systems uses attempts and timeouts options instead of the old retrans and retry options.
Query caching support based on TTL of responses. Can be enabled via ares_init_options() with ARES_OPT_QUERY_CACHE.
Bugfixes:
ares_init_options() for ARES_OPT_UDP_PORT and ARES_OPT_TCP_PORT accept theport in host byte order, but it was reading it as network byte order. Regression introduced in 1.20.0.
ares_init_options() for ARES_FLAG_NOSEARCH was not being honored forares_getaddrinfo() or ares_gethostbyname(). Regression introduced in 1.16.0.
Autotools MacOS and iOS version check was failing
Environment variables passed to c-ares are meant to be an override for system configuration. Regression introduced in 1.22.0.
Spelling fixes as detected by codespell.
The timeout returned by ares_timeout() was truncated to milliseconds butvalidated to microseconds which could cause a user to attempt to process timeouts prior to the timeout actually expiring.
CMake was not honoring CXXFLAGS passed in via the environment which couldcause compile and link errors with distribution hardening flags during packaging.
Fix Windows UWP and Cygwin compilation.
ares_set_servers_*() for legacy reasons needs to accept an empty server listand zero out all servers. This results in an inoperable channel and thus is only used in simulation testing, but we don't want to break users. Regression introduced in 1.21.0.
Changes in version 1.22.1
Bugfixes:
Fix /etc/hosts processing performance with all entries using same IPaddress. Large hosts files using the same IP address for all entries could use exponential time.
Fix typos in manpages
Fix OpenWatcom building
Changes in version 1.22.0
Features:
ares_reinit() is now implemented to re-read any system configuration and immediately apply to an existing ares channel
The adig command line program has been rewritten and its format now more closely matches that of BIND's dig utility
The new DNS message parser and writer functions have now been made public
RFC9460 HTTPS and SVCB records are now supported
RFC6698 TLSA records are now supported
The server list is now internally dynamic and can be changed without impacting existing queries
Hosts file processing is now cached until the file is detected to be changed to speed up repetitive lookups of large hosts files
Changes:
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/c-ares?expand=0&rev=56
* Remove bin/acountry from built tools as nerd.dk is gone
* Default per-query timeout has been reduced to 2s with a 3x retry count

destruction
* ares_getaddrinfo() should not retry other address classes if
one address class has already been returned
* Avoid production ill-formed result when qualifying a name
with the root domain
* Fix missing prefix for CMake generated libcares.pc
* DNS server ports can now be read from system configuration
instead of defaulting to port 53, aka openBSD resolv.conf format
* Replace usages of sprintf with snprintf

- Update to version 1.19.0
Security:
* Low. Stack overflow in ares_set_sortlist() which is used
during c-ares initialization and typically provided by an
administrator and not an end user.
Changes:
* Add ARES_OPT_HOSTS_FILE similar to ARES_OPT_RESOLVCONF for
specifying a custom hosts file location.
Bug fixes:
* Fix memory leak in reading /etc/hosts when using localhost
fallback.
* Fix chain building c-ares when libresolv is already included by
another project.
* File lookup should not immediately abort as there may be other
tries due to search criteria.
* Asterisks should be allowed in host validation as CNAMEs may
reference wildcard domains.
* AutoTools build system referenced bad STDC_HEADERS macro.
* Even if one address class returns a failure for
ares_getaddrinfo() we should still return the results we have.
* Fix ares_getaddrinfo() numerical address resolution with
AF_UNSPEC
* Fix tools and help information.
* Various documentation fixes and cleanups.
* Add include guards to ares_data.h
* c-ares could try to exceed maximum number of iovec entries
supported by system.

* Allow '/' as a valid character for a returned name for
CNAME in-addr.arpa delegation
* no longer forwards requests for localhost resolution per RFC6761
* During a domain search, treat ARES_ENODATA as ARES_NXDOMAIN so
that the search process will continue to the next domain
in the search.
* Provide ares_nameser.h as a public interface as needed by NodeJS
* Add support for URI(Uniform Resource Identifier) records via
ares_parse_uri_reply()

OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/c-ares?expand=0&rev=44
Security:
* When building c-ares with CMake, the RANDOM_FILE would not be set
and therefore downgrade to the less secure random number generator
* If ares_getaddrinfo() was terminated by an ares_destroy(),
it would cause a crash
* Crash in sortaddrinfo() if the list size equals 0 due to
an unexpected DNS response
* Expand number of escaped characters in DNS replies as per
RFC1035 5.1 to prevent spoofing follow-up
(bsc#1188881, CVE-2021-3672)
* Perform validation on hostnames to prevent possible XSS
due to applications not performing valiation themselves
Changes:
* ares_malloc(0) is now defined behavior (returns NULL) rather than system-specific to catch edge cases
Bug fixes:
* Building tests should not force building of static libraries except on Windows
* Relative headers must use double quotes to prevent pulling in a system library

- update to 1.17.1:
Travis: add iOS target built with CMake (#378)
Issue #377 suggested that CMake builds for iOS with c-ares were broken. This PR adds an automatic Travis build for iOS CMake.
- fix build
External projects were using non-public header ares_dns.h, make public again (#376)
It appears some outside projects were relying on macros in ares_dns.h, even
though it doesn't appear that header was ever meant to be public. That said,
we don't want to break external integrators so we should distribute this header
again.
- note that so versioning has moved to configure.ac
- note about 1.17.1

Security:
* avoid read-heap-buffer-overflow in ares_parse_soa_reply found during
fuzzing
* Avoid theoretical buffer overflow in RC4 loop comparison
* Empty hquery->name could lead to invalid memory access
* ares_parse_{a,aaaa}_reply() could return a larger *naddrttls than was
passed in (bsc#1178882, CVE-2020-8277)

ports to prevent failures in containers
* Detect remote DNS server does not support EDNS using rules from RFC 6891
* Source tree has been reorganized to use a more modern layout
* Allow parsing of CAA Resource Record
Bug fixes:
* readaddrinfo bad sizeof()
* Test cases should honor HAVE_WRITEV flag, not depend on WIN32
* FQDN with trailing period should be queried first
* ares_getaddrinfo() was returning members of the struct as garbage values if
unset, and was not honoring ai_socktype and ai_protocol hints.
* ares_gethostbyname() with AF_UNSPEC and an ip address would fail
* Properly document ares_set_local_ip4() uses host byte order

- Version update to 1.16.1
Security:
* Prevent possible use-after-free and double-free in ares_getaddrinfo() if
ares_destroy() is called prior to ares_getaddrinfo() completing.
Reported by Jann Horn at Google Project Zero.
Changes:
* Allow TXT records on CHAOS qclass. Used for retriving things like
version.bind, version.server, authoris.bind, hostname.bind, and id.server. [3]
Bug fixes:
* Fix Windows Unicode incompatibilities with ares_getaddrinfo() [1]
* Silence false cast-align compiler warnings due to valid casts of struct
sockaddr to struct sockaddr_in and struct sockaddr_in6.
* MacOS should use libresolv for retrieving DNS servers, like iOS
* CMake build system should populate the INCLUDE_DIRECTORIES property of
installed targets [2]
* Correct macros in use for the ares_getaddrinfo.3 man page
- Changes in version 1.16.0
Changes:
* Introduction of ares_getaddrinfo() API which provides similar output
(including proper sorting as per RFC 6724) to the system native API, but
utilizes different data structures in order to provide additional
information such as TTLs and all aliases. Please reference the respective
man pages for usage details.
* Parse SOA records from ns_t_any response
* CMake: Provide c-ares version in package export file
* CMake: Add CPACK functionality for DEB and RPM
* CMake: Generate PDB files during build
* CMake: Support manpage installation
Bug fixes:
* Fix bad expectation in IPv6 localhost test.
* AutoTools: use XC_CHECK_BUILD_FLAGS instead of XC_CHECK_USER_FLAGS to
prevent complaints about CPPFLAGS in CFLAGS.
* Fix .onion handling
* Command line usage was out of date for adig and ahost.
* Typos in manpages
* If ares_getenv is defined, it must return a value on all platforms
* If /etc/resolv.conf has invalid lookup values, use the defaults.
* Tests: Separate live tests from SetServers* tests as only live tests
should require internet access.
* ares_gethostbyname() should return ENODATA if no valid A or AAAA record
is found, but a CNAME was found.
* CMake: Rework library function checking to prevent unintended linking
with system libraries that aren't needed.
* Due to use of inet_addr() it was not possible to return 255.255.255.255
from ares_gethostbyname().
* CMake: Fix building of tests on Windows

- disable-live-tests.patch: refreshed
- regression.patch: fix a regression in DNS results that contain
both A and AAAA answers.
- Add netcfg as the build requirement and runtime requirement.
ares_getaddrinfo function uses the getservbyport_r function which
requires the /etc/services file to function properly. That config
file is provided by the netcfg package. Unit tests rely on it
too, hence it has to be a build dependency as well.
