c-ares version 1.24.0 |
||||
c-ares version 1.25.0 |
||||
|
||||
This is a feature and bugfix release. |
||||
|
||||
Features: |
||||
o Add support for IPv6 link-local DNS servers. Nameserver formats can now |
||||
accept the %iface suffix, and a new ares_get_servers_csv() function was |
||||
added to return servers that can contain the link-local interface name. [3] |
||||
This is a maintenance release. |
||||
|
||||
Changes: |
||||
o Unbundle GoogleTest for test cases. Package maintainers will now need to |
||||
require GoogleTest (GMock) as a build dependency if building tests. New |
||||
GoogleTest versions require C++14 or later. [6] |
||||
o Replace nameserver parsing code to use new memory-safe functions. [1] |
||||
o Replace the sortlist parser with new memory-safe functions. [5] |
||||
o Various warning fixes and dead code removal. |
||||
o AutoTools: rewrite build system to be lighter weight and fix issues in some |
||||
semi-modern systems. It is likely this has broken building on some less |
||||
common and legacy OSs, please report issues. [1] |
||||
o Rewrite ares_strsplit() as a wrapper for ares__buf_split() for memory |
||||
safety reasons. [4] |
||||
o The ahost utility now uses ares_getaddrinfo() and returns both IPv4 and |
||||
IPv6 addresses by default. [6] |
||||
o OpenBSD: Add SOCK_DNS flag when creating socket. [12] |
||||
|
||||
Bug Fixes: |
||||
o Old Linux versions require POSIX_C_SOURCE or _GNU_SOURCE to compile with |
||||
thread safety support. [2] |
||||
o A non-responsive DNS server that caused timeouts wouldn't increment the |
||||
failure count, this would lead to other servers not being tried. |
||||
Regression introduced in 1.22.0. [4] |
||||
o Some projects that depend on c-ares expect invalid parameter option values |
||||
passed into ares_init_options() to simply be ignored. This behavior has |
||||
been restored. [7] |
||||
o On linux getrandom() can fail if the kernel doesn't support the syscall, |
||||
fall back to another random source. [8] |
||||
o 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. [9] |
||||
|
||||
o Tests: Live reverse lookups for Google's public DNS servers no longer |
||||
return results, replace with CloudFlare pubic DNS servers. [2] |
||||
o MacOS legacy SDKs require sys/socket.h before net/if.h [3] |
||||
o Connection failures should increment the server failure count first or a |
||||
retry might be enqueued to the same server. [5] |
||||
o On systems that don't implement the ability to enumerate network interfaces |
||||
the stubs used the wrong prototype. [7] |
||||
o Fix minor warnings and documentation typos. [8] |
||||
o Fix support for older GoogleTest versions. [9] |
||||
o getrandom() may require sys/random.h on some systems. [10] |
||||
o Fix building tests with symbol hiding enabled. [11] |
