- c-ares 1.28.1
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]
  * CMake: Fix Chain building if CMAKE runtime paths not set
  * NDots configuration should allow a value of zero. [PR #735]

- c-ares 1.27.0
  Security:
  * Moderate. CVE-2024-25629. Reading malformatted /etc/resolv.conf,
    /etc/nsswitch.conf or the HOSTALIASES file could result in a crash.
    GHSA-mg26-v6qh-x48q (CVE-2024-25629, bsc#1220279)
  Features:
  * New function ares_queue_active_queries() to retrieve number of in-flight
    queries. PR #712
  * New function ares_queue_wait_empty() to wait for the number of 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
  Changes:
  * EDNS Packet size should be 1232 as per DNS Flag Day. PR #705
  Bugfixes:
  * Fix warning due to ignoring return code of write(). PR #709
  * CMake: don't override target output locations if not top-level. Issue #708
  * Fix building c-ares without thread support. PR #700

- Ensure multibuild flavors result in different src names.

- c-ares 1.26.0:
  * Event Thread support. Integrators are no longer required to
    monitor the file descriptors registered by c-ares for events
    and call ares_process() when enabling the event thread feature
    via ARES_OPT_EVENT_THREAD passed to ares_init_options().
  * Added flags to are_dns_parse() to force RAW packet parsing
  * Mark ares_fds() as deprecated
  * Bug fixes
- move tests into a build flavor to avoid gtest/gmock build loop

- Update to version 1.25
Changes:
 o Rewrite ares_strsplit() as a wrapper for ares__buf_split() for memory
   safety reasons.
 o The ahost utility now uses ares_getaddrinfo() and returns both IPv4 and
   IPv6 addresses by default.
Bug Fixes:
 o Tests: Live reverse lookups for Google's public DNS servers no longer
   return results, replace with CloudFlare pubic DNS servers.
 o Connection failures should increment the server failure count first or a
   retry might be enqueued to the same server
 o On systems that don't implement the ability to enumerate network interfaces
   the stubs used the wrong prototype.
 o Fix minor warnings and documentation typos
 o Fix support for older GoogleTest versions
 o getrandom() may require sys/random.h on some systems.
 o Fix building tests with symbol hiding enabled.
- 0001-Use-RPM-compiler-options.patch: dropped, obsolete

- update to 1.18.1. Changes since 1.17.2:
  * 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()
- disable unit tests for SLE12 since GCC compiler too old to build
  unit tests
- 5c995d5.patch: upstreamed
- disable-live-tests.patch: refreshed

- new upstream website
- drop multibuild - tests do not require static library anymore
- spec file cleanup
- drop sources that were re-added to upstream distibution
  (c-ares-config.cmake.in ares_dns.h libcares.pc.cmake) 

- 5c995d5.patch: augment input validation on hostnames to allow _
  as part of DNS response (bsc#1190225)

• Files Changed
• Browse Source

- update to 1.17.2:
  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

  Changes:
  * Update help information for adig, acountry, and ahost
  * Test Suite now uses dynamic system-assigned ports rather than hardcoded

  * 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

- simplify conditions bit to make it tad more readable

- Implement multibuild specfile to split out tests into its own
  flavor; this way we can build and run tests, which require
  static lib, as well as avoid packaging the latter without issues
  with the installed cmake file..

- Upgrade to latest snapshot from 2020-01-17
- 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.

- Switch to cmake-based build.
  Some packages need the cmake build files.
