Changelog for the c-ares project. Generated with git2changes.pl
+Version 1.17.1 (19 Nov 2020)
+
+GitHub (19 Nov 2020)
+- [Brad House brought this change]
+
+ 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 By: Brad House (@bradh352)
+
+bradh352 (18 Nov 2020)
+- fix build
+
+GitHub (18 Nov 2020)
+- [Fabrice Fontaine brought this change]
+
+ 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.
+
+ Fix By: Fabrice Fontaine (@ffontaine)
+
+bradh352 (17 Nov 2020)
+- note that so versioning has moved to configure.ac
+
+- note about 1.17.1
+
+- fix sed gone wrong
+
+GitHub (17 Nov 2020)
+- [Daniel Stenberg brought this change]
+
+ autotools cleanup (#372)
+
+ * remove: install-sh mkinstalldirs
+
+ They're generated when needed, no need to store in it.
+
+ * buildconf: remove custom logic with autoreconf
+
+ Fix By: Daniel Stenberg (@bagder)
+
+bradh352 (17 Nov 2020)

+- 1.17.0 release prep
+
+- ares_getaddrinfo(): duplicate hints ai_socktype and ai_protocol into output
+
+ ai_socktype and ai_protocol were ignored from the hints input. They are now
+ duplicated into the output as expected. Currently no sanity checks on
+ proper values are taking place.
+
+ Fixes: #317
+ Fix By: Brad House (@bradh352)
+
+- ares_parse_{a,aaaa}_reply could return larger *naddrttls than passed in
+
+ If there are more ttls returned than the maximum provided by the requestor, then
+ the *naddrttls response would be larger than the actual number of elements in
+ the addrttls array.
+
+ This bug could lead to invalid memory accesses in applications using c-ares.
+
+ This behavior appeared to break with PR #257
+
+ Fixes: #371
+ Reported By: Momtchil Momtchev (@mmomtchev)
+ Fix By: Brad House (@bradh352)
+
+GitHub (5 Nov 2020)
+- [Dustin Lundquist brought this change]
+
+ docs: ares_set_local_ip4() uses host byte order (#368)
+

+ Tests should use dynamic system-assigned ports rather than static port (#346)

+ The c-ares test suite was hardcoded to use port 5300 (and possibly 5301, 5302) for the test suite. Especially in containers, there may be no guarantee these ports are available and cause tests to fail when they could otherwise succeed. Instead, request the system to assign a port to use dynamically. This is now the default. To override, the test suite still takes the "-p <port>" option as it always has and will honor that.

+
+ The basic idea of sticking to RFC that a ns_t_any too should return an SOA record is something open for discussion but I have kept the functionality intact as it was previously i.e the function returns ARES_EBADRESP if it doesn't find a SOA record regardless of which response it is parsing i.e. T_SOA or T_ANY.

+ Apply the IPv6 server blacklist to all nameserver sources, not just Windows (#193)
+
+ For #164, I mentioned that it seemed like the IPv6 nameserver blacklist should apply to all OSes. In a mailing list post, @bradh352 agreed and suggested that I file a PR to make it so.
+
+ This moves the blacklist check from being Windows-specific to being a general feature of config_nameservers(), no matter the nameserver source. It also simplifies the ares_ipv6_server_blacklisted() implementation to not parse and re-parse the blacklisted IPv6 addresses from strings on every check. I think they're almost as easy to read as a sequence of hex bytes in an array initializer, and it's definitely less work on each trip through the code.

+
+ The allocation function change is probably the only one that needs explanation. MSVC gives warnings about the function pointers not being stable across DLL boundaries or something to that effect, so for Windows, I've made them be called indirectly, which at least made the compiler happy. I can't say I've tested every linking combination on Windows with them before or after the change, but it seems harmless.

+
+ Harden and rationalize c-ares timeout computation (#187)
+
+ * Harden and rationalize c-ares timeout computation
+ * Remove the rand() part of the timeout calculation completely.
+
+ When c-ares sends a DNS query, it computes the timeout for that request as follows:
+
+ timeplus = channel->timeout << (query->try_count / channel->nservers);
+ timeplus = (timeplus * (9 + (rand () & 7))) / 16;
+ I see two issues with this code. Firstly, when either try_count or channel->timeout are large enough, this can end up as an illegal shift.
+
+ Secondly, the algorithm for adding the random timeout (added in 2009) is surprising. The original commit that introduced this algorithm says it was done to avoid a "packet storm". But, the algorithm appears to only reduce the timeout by an amount proportional to the scaled timeout's magnitude. It isn't clear to me that, for example, cutting a 30 second timeout almost in half to roughly 17 seconds is appropriate. Even with the default timeout of 5000 ms, this algorithm computes values between 2812 ms and 5000 ms, which is enough to cause a slightly latent DNS response to get spuriously dropped.
+
+ If preventing the timers from all expiring at the same time really is desirable, then it seems better to extend the timeout by a small factor so that the application gets at least the timeout it asked for, and maybe a little more. In my experience, this is common practice for timeouts: applications expect that a timeout will happen at or after the designated time (but not before), allowing for delay in detecting and reporting the timeout. Furthermore, it seems like the timeout shouldn't be extended by very much (we don't want a 30 second timeout changing into a 45 second timeout, either).
+
+ Consider also the documentation of channel->timeout in ares_init_options():
+
+ The number of milliseconds each name server is given to respond to a query on the first try. (After the first try, the timeout algorithm becomes more complicated, but scales linearly with the value of timeout.) The default is five seconds.
+
+ In the current implementation, even the first try does not use the value that the user supplies; it will use anywhere between 56% and 100% of that value.
+
+ The attached patch attempts to address all of these concerns without trying to make the algorithm much more sophisticated. After performing a safe shift, this patch simply adds a small random timeout to the computed value of between 0 ms and 511 ms. I could see limiting the random amount to be no greater than a proportion of the configured magnitude, but I can't see scaling the random with the overall computed timeout. As far as I understand, the goal is just to schedule retries "not at the same exact time", so a small difference seems sufficient.
+
+ UPDATE: randomization removed.

+ Fix DNS server lookup breaking with Android O due to Android removing access to net.dns# system properties. (#148)
+
+ As of Android 8 (Oreo) access to net.dns# has been removed (https://developer.android.com/about/versions/oreo/android-8.0-changes.html). The reasoning given is that it, "improves privacy on the platform". Currently c-ares uses this to get the list of DNS servers.
+
+ Now the only way to access the DNS server list is by using the Connectivity Manager though Java. This adds the necessary JNI code to use the Connectivity Manager and pull the DNS server list. The old way using __system_property_get with net.dns# remains for compatibilty.
+
+ Using the Connectivity Manager requires the ACCESS_NETWORK_STATE permission to be set on the app. Existing applications most likely are not setting this and keeping the previous method as a fallback will at the very least ensure those apps don't break on older versions of Android. They will need to add this permission for Android 8 compatibility.
+
+ Included in the patch are two initalization functions which are required. The JVM must be registered as well as the Connectivity Manager itself. There is no way to get the Connectivity Manager except though Java. Either being passed down to C directly or by passing in an Android Context which can be used to get the Connectivity Manager. Examples are provided in the documentation.

+ Support for suffix search lists was already built in for Linux. The search list could be set via set_search. With this change the suffix search list from Windows is read from the registry and then set into the ares configuration via set_search. There are two sources for the search list:

+ The global DNS suffix search list.
+ The primary and connection specific DNS suffixes if the global is not available.

+ Windows DNS server sorting (#81)
+
+ Original Patch From Brad Spencer:
+ https://c-ares.haxx.se/mail/c-ares-archive-2016-04/0000.shtml
+
+ My modifications include:
+ * Dynamically find GetBestRoute2 since it is a Windows Vista+ symbol, and will fall back to prior behavior when not available.
+ * Prefer get_DNS_AdaptersAddresses as the modifications should alleviate the concerns which caused us to prefer get_DNS_NetworkParams
+ * Update AppVeyor to use MinGW-w64 instead of the legacy MinGW
+ * Fix compile error in test suite for Windows.
+
+ Original message from patch below:
+
+ From: Brad Spencer <bspencer@blackberry.com>
+ Date: Fri, 29 Apr 2016 14:26:23 -0300
+
+ On Windows, the c-ares DNS resolver tries first to get a full list of
+ DNS server addresses by enumerating the system's IPv4/v6 interfaces and
+ then getting the per-interface DNS server lists from those interfaces
+ and joining them together. The OS, at least in the way the c-ares
+ prefers to query them (which also may be the only or best way in some
+ environments), does not provide a unified list of DNS servers ordered
+ according to "current network conditions". Currently, c-ares will then
+ try to use them in whatever order the nested enumeration produces, which
+ may result in DNS requests being sent to servers on one interface
+ (hosting the current default route, for example) that are only intended
+ to be used via another interface (intended to be used when the first
+ interface is not available, for example). This, in turn, can lead to
+ spurious failures and timeouts simply because of the server address
+ order that resulted because of the enumeration process.
+
+ This patch makes the (safe?) assumption that there is no other better
+ rule to chose which interface's DNS server list should be prioritized.
+ After all, a DNS lookup isn't something "per network"; applications
+ don't look up "these DNS names on this interface and those DNS names on
+ that interface". There is a single resource pool of DNS servers and the
+ application should presume that any server will give it the "right"
+ answer. However, even if all DNS servers are assumed to give equally
+ useful responses, it is reasonable to expect that some DNS servers will
+ not accept requests on all interfaces. This patch avoids the problem by
+ sorting the DNS server addresses using the Windows IPv4/v6 routing tables.
+
+ For example, a request to DNS server C on interface 2 that is actually
+ sent over interface 1 (which may happen to have the default route) may
+ be rejected by or not delivered to DNS server C. So, better to use DNS
+ servers A and B associated with interface 1, at least as a first try.
+
+ By using the metric of the route to the DNS server itself as a proxy for
+ priority of the DNS server in the list, this patch is able to adapt
+ dynamically to changes in the interface list, the DNS server lists per
+ interface, which interfaces are active, the routing table, and so on,
+ while always picking a good "best" DNS server first.
+
+ In cases where any DNS server on any interface will do, this patch still
+ seems useful because it will prioritize a lower-metric route's (and thus
+ interface's) servers.

-- Adjust WIN32 freeaddrinfo, getaddrinfo and getnameinfo availability
-
-- WIN32 availability of freeaddrinfo, getaddrinfo and getnameinfo functions is quite
- convoluted, compiler dependant and in some cases even build target dependat.
-
-- check for freeaddrinfo() at configuration phase
-
-- update aclocal file serial number
-
-- remove verification of the freeability of the addrinfo struct pointer members
-
-- fix comment
-
-- make CHECK_FUNC_GETADDRINFO_UNFREEABLE_AI_ADDR
- and CHECK_FUNC_GETADDRINFO_UNFREEABLE_AI_CANONNAME
- internal to CHECK_FUNC_GETADDRINFO
-
-- fix leftover
-
-- Initial attempt to detect at configuration time if the getaddrinfo()
- function returns an addrinfo with an unfreeable ai_canonname member ptr.
-
-- Initial attempt to detect at configuration time if the getaddrinfo()
- function returns an addrinfo with an unfreeable ai_addr member ptr.
-
-- icc adjustments:
-
- Select ANSI C89 dialect plus GNU extensions, again.
-
-- some more temporary magic for the icc seg-fault issue
-
-- icc permanent adjustment:
-
- Select precise floating-point model, otherwise doubles are less than 64-bit wide
-
- icc test adjustment:
-
- Select c89 dialect
-
-- icc adjustments:
-
- Enable more icc warnings.
-
- Optimization disabling options used only for icc 9.1
-
-- #include <stdlib.h> for exit() prototype
-
-- some more temporary magic for the icc seg-fault issue
-
-- remove from configure.ac temporary magic for the icc seg-fault issue
-
-- some more temporary magic for the icc seg-fault issue
-
-- Charles Hardin patch:
-
- - handles the EINPROGRESS for UDP connects
- - uses closesocket instead of close on some paths that were noticed
-
-- some more temporary magic for the icc seg-fault issue
-
-- messages initially intended only for debug purposes, now become permanent
- since these are extremely useful when compiler rejects a set of options.
-
-- fix compiler warning
-
-- fix missing double-quotes
-
-Daniel Stenberg (17 Oct 2008)
-- Charles Hardin made adig support a regular numerical dotted IP address for the
- -s option as well.
-
-Yang Tse (16 Oct 2008)
-- some more temporary magic for the icc seg-fault issue
-
-- Ensure that shell variable contents which have active meaning
- to the shell echo command are not interpreted when trying to
- remove extra whitespace from shell variable content.
-
-- Adjust Watcom C warnings:
-
- Disable warnings on structure members padding.
-
-- With this change Solaris target builds will now be done with _REENTRANT defined.
-
-- Adjust Tiny C basic options:
-
- Remove -b from debug-enabled configuration, as Tiny C might have
- been built without the memory and bounds checker support.
-
-- Adjust GCC warnings:
-
- Better disable following warnings when cross-compiling with a gcc older
- than 3.0, to avoid warnings from third party system headers:
-
- -Wmissing-declarations
- -Wmissing-prototypes
- -Wunused
- -Wshadow
-
-- fix syntax error
-
-- Initial attempt to detect Watcom C compiler
-
-- make naming scheme more consistent across whole file
-
-- Adjust GCC warnings:
-
- Disable following warnings when cross-compiling with a gcc older
- than 3.0, to avoid warnings from third party system headers:
-
- -Wmissing-prototypes
- -Wunused
- -Wshadow
-
-- Adjust GCC --enable-warnings:
-
- Do not enable -pedantic when cross-compiling with a gcc older
- than 3.0, to avoid warnings from third party system headers.
-
-- adjust SGI MIPSpro C detection
-
-- LCC compiler adjustments:
-
- Highest warning level is double -A, next is single -A.
- Due to the big number of warnings these trigger on third
- party header files it is impratical for us to use any of
- them here. If you want them simply define it in CPPFLAGS.
-
-- remove extra space
-
-- split SGI compiler check. One for MIPS C and another for MIPSpro C
-
-- LCC compiler adjustments:
-
- Warning level reduced from double -A to single -A
-
-- Initial attempt to detect Tiny C compiler
-
-- Initial attempt to detect LCC compiler
-
-- 1) fix bug in CONVERT_INCLUDE_TO_ISYSTEM
-
- 2) Disable SGI remark: controlling expression is constant
-
-- simplify SGI C compiler check
-
-- HP C adjustments:
-
- Due to the HP-UX socklen_t issue it is insane to use the +w1 warning level.
- It generates more than 1100 warnings on socklen_t related statements.
-
- Until the issue is somehow fixed we will just use the +w2 warning level.
-
-- Add debug tracing for COMPILER_WORKS_IFELSE
-
-- configure will also warn on 'strict compiler warning' rejected options
-
-- convert rejected compiler options messages into a warnings
-
-- remove extra whitespace from string in SGI C check
-
-- oops
-
-- Initial attempt to detect SGI C compiler
-
-- HP C adjustments:
-
- Disallow run-time dereferencing of null pointers.
-
- Disable some remarks:
-
- #4227: padding struct with n bytes to align member.
-
- #4255: padding size of struct with n bytes to alignment boundary.
-
-- improve presentation of accepted/rejected debug/optimizer options
-
-- refactoring of COMPILER_BASIC_OPTS

-- adjust ICC_windows settings
-
-- fix VAR_STRIP
-
-- Sync up with reality
-
-- Initial attempt to support configure's --(dis|en)able-optimize
- option to specify dis(activation) of compiler optimizations.
-
- If option is specified, it will be honored independant of the
- --(dis|en)able-debug option.
-
-- fix comment
-
-- Initial attempt to support configure's --(dis|en)able-warnings
- option to specify dis(activation) of picky compiler warnings.
-
- If option is specified, it will be honored independant of the
- --(dis|en)able-debug option.
-
- If option is not specified, it will follow --(dis|en)able-debug
- setting, whose default is disabled if not specified.
-
-- fix compiler warning: dereferencing type-punned pointer will break strict-aliasing rules
-
-- now compiler warnings are activated for all gcc builds, not only debug ones.
-
-- Use CFLAGS for icc linker options instead of LDFLAGS,
- otherwise gethostbyname() is not detected.
-
-- use ac_cv_compiler and ac_cv_compiler_num to keep compiler ID and version number
-
-- Temporary icc adjustment:
-
- Disable floating point optimizations
-
-- HAVE_INET_PTON will only be defined when an IPv6 capable working
- inet_pton function is available.
-
-- HAVE_INET_NTOP will only be defined when an IPv6 capable working
- inet_ntop function is available.
-
-- ntoa() and inet_ntoa_r() no longer used
-
-- icc adjustments for icc 9.0 and prior versions:
-
- Disable remark #279: controlling expression is constant
-
- Remark triggered mostly on va_arg() and FD_ZERO() macros.
-
-- attempt to make work the gethostname function
- check for winsock build target configurations
-
-Gisle Vanem (21 Sep 2008)
-- Added HAVE_NETDB_H, HAVE_ARPA_INET_H, HAVE_STRCASECMP
- and HAVE_STRNCASECMP.
-
-Yang Tse (19 Sep 2008)
-- icc adjustments:
-
- Disable remark #981: operands are evaluated in unspecified order
-
- Function calls which are triggering this remark, today, do not depend
- on the order of evaluation of its arguments.
-
- Disable remark #1469: "cc" clobber ignored
-
- Remark triggered on htons() and ntohs() due to glibc header files.
-
-- icc adjustments
-
-- fix netdb.h prerequisite inclusion
-
-- improve detection of getservbyport_r()
-
-- On Linux Intel's icc uses gcc's header files, so
- we select ANSI C89 dialect plus GNU extensions.
-
-- improve detection of gethostname()
-
-- NetWare builds include "nameser.h" from the c-ares subdir
-
-- include <strings.h>
-
-- Sync up with reality
-
-- adjust inclusion of "nameser.h"
-
-- reorder some lines in file
-
-- code cleanup
-
-- NetWare seems to have writev()
-
-- rearrange to allow internal/private use of ares_writev to any system
- that lacks the writev function.
-
-- NetWare CLIB target has stricmp() and strnicmp()
-
-- include header file only when available
-
-- rearrange to allow internal/private use of ares_strcasecmp to any system that
- lacks the strcasecmp function.
-
-- improve detection of:
- strcasecmp()
- strcmpi()
- stricmp()
- strncasecmp()
- strncmpi()
- strnicmp()
-
-- *** empty log message ***
-
-Gisle Vanem (12 Sep 2008)
-- djgpp does have strdup().
-
-Yang Tse (12 Sep 2008)
-- change CRLF into LF line endings
-
-- strdup() clone for systems/configurations which lack it
-
-- move inclusion of ares_private.h last
-
-- icc adjustments
-
-- icc adjustments
-
-- Select strict ANSI C89 conformance for icc
-
-- remove unnecessary typecasting of malloc()
-
-- remove unnecessary typecasting of realloc()
-
-Daniel Stenberg (29 Aug 2008)

-
-Version 1.5.3 (29 Aug 2008)
-
-Daniel Stenberg (29 Aug 2008)

-- Ops, remove 'use_vc'.
-
-- Support Watt-32 under Win32.
-
-Yang Tse (10 Aug 2008)
-- Fix: Remove now this SIZEOF_CURL_OFF_T symbol definition.
-
- This should have been done with the initial 64-bit curl_off_t patch.
-
-- Improve CURL_CHECK_DEF
-
-- Fix IBM C and DEC/Compaq C compiler detection
-
-- Initial support of curlbuild.h and curlrules.h which allows
- to have a curl_off_t data type no longer gated to off_t.
-
-- The minimum autoconf version required for this file is 2.50
-
- Avoid dot notation in aclocal serial file number, use a single number now.
-
-Daniel Stenberg (4 Aug 2008)
-- - Fix by Tofu Linden:
-
- The symptom:
- * Users (usually, but not always) on 2-Wire routers and the Comcast service
- and a wired connection to their router would find that the second and
- subsequent DNS lookups from fresh processes using c-ares to resolve the same
- address would cause the process to never see a reply (it keeps polling for
- around 1m15s before giving up).
-
- The repro:
- * On such a machine (and yeah, it took us a lot of QA to find the systems
- that reproduce such a specific problem!), do 'ahost www.secondlife.com',
- then do it again. The first process's lookup will work, subsequent lookups
- will time-out and fail.
-
- The cause:
- * init_id_key() was calling randomize_key() *before* it initialized
- key->state, meaning that the randomness generated by randomize_key() is
- immediately overwritten with deterministic values. (/dev/urandom was also
- being read incorrectly in the c-ares version we were using, but this was
- fixed in a later version.)
- * This makes the stream of generated query-IDs from any new c-ares process
- be an identical and predictable sequence of IDs.
- * This makes the 2-Wire's default built-in DNS server detect these queries
- as probable-duplicates and (erroneously) not respond at all.
-
-Yang Tse (4 Aug 2008)
-- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
- Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. But,
- autoconf 2.62 version of AC_AIX defines _ALL_SOURCE along with other four
- preprocessor symbols no matter if the system is AIX or not. To keep the
- traditional behaviour, as well as an uniform one, across autoconf versions
- AC_AIX is replaced with our own internal macro.
-
-- Adjust DEC/Compaq C compiler settings.
-
-- Another AC_TRY_LINK conversion to AC_LINK_IFELSE.
- Proper definition of HAVE_function if function is found deeper.
-
-- Sync up with reality
-
-- Rename reentrant.m4 to avoid filename clash.
-
-- Add file version serial number that might be used by 'aclocal' and others.
-
- Keep the '#' character as the first one on the line.
-
-- Update copyright year.
-
-- Sync comment with reality.
-
-- Reinstate the 'aclocal -I m4' in buildconf and 'ACLOCAL_AMFLAGS = -I m4' way of
- including our local m4/reentrant.m4 file. This even takes care of including the
- file in the distribution tarball.
-
-- Add quoting for the AC_DEFINE arguments.
-
-- Also remove the whitespace.
-
-- Also remove the extra quoting.
-
-- Replace some '@%:@' quadigraphs by its actual representation '#'.
-
- This quadigraph used before a C preprocessor 'define' directive could
- be fooling M4, when processing this file, and make it think that the
- line contains a pure M4 'define' macro.
-
-- Tests done using 'aclocal -I m4' in buildconf and 'ACLOCAL_AMFLAGS = -I m4
- in top Makefile.am triggered a problem that prevented aclocal from running
- successfully on SunOS 5.10 with GNU m4 1.4.5 and GNU Autoconf 2.61
-
- A tarball which reproduces mentioned problem is the one dated July-28-2008
- http://cool.haxx.se/curl-daily/curl-7.19.0-20080728.tar.gz
-
- We actually don't need all the bells and whistles that the above mechanism
- provides. We only need to include our m4/reentrant.m4 file in acinclude.m4
- so here we go with this simpler mechanism.
-
-- for debugging purposes show ACLOCAL_FLAGS
-
-- These lines were unintentionally removed in previous commit
-
-- Partially undo change that prevented SED, GREP, EGREP and AR from being changed by libtool or autoconf.
-
-- Assert that SED and GREP are set
-
-- Require autoconf 2.57 or newer
-
-- When calling aclocal, user defined ACLOCAL_FLAGS will now precede ours.
-
-- move ACLOCAL_AMFLAGS after AUTOMAKE_OPTIONS
-
-- setup.h handles definition of _REENTRANT based on NEED_REENTRANT
- definition which might be defined in config.h or config-*.h files
-
-- Remove explicit inclusion of our m4 files first. It was interesting as a test,
- but it breaks aclocal execution on some systems, with the following error:
-
- Can't locate object method "rel2abs" via package "File::Spec" at /usr/local/bin/aclocal line 256.
-
-- Another step towards detecting if _REENTRANT is already defined or actually
- needed, and being able to define it if appropriate for further configure tests
- as well as for the generated config file.
-
-- Explicitly include our m4 files first. This might minimize the impact
- that other package's underquoted m4 function definitions have on ours.
-
-- Add a 3 argument check for getprotobyname_r

- How To Compile
-
-Installing Binary Packages
-==========================
-
- Lots of people download binary distributions of c-ares. This document
- does not describe how to install c-ares using such a binary package.
- This document describes how to compile, build and install c-ares from
- source code.
-
-Building from git
-=================
-
- If you get your code off a git repository, see the GIT-INFO file in the
- root directory for specific instructions on how to proceed.
-
-UNIX
-====
- A normal unix installation is made in three or four steps (after you've
- unpacked the source archive):
-
- ./configure
- make
- make ahost adig acountry (optional)
- make install
-
- You probably need to be root when doing the last command.
-
- If you have checked out the sources from the git repository, read the
- GIT-INFO on how to proceed.
-
- Get a full listing of all available configure options by invoking it like:
-
- ./configure --help
-
- If you want to install c-ares in a different file hierarchy than /usr/local,
- you need to specify that already when running configure:
-
- ./configure --prefix=/path/to/c-ares/tree
-
- If you happen to have write permission in that directory, you can do 'make
- install' without being root. An example of this would be to make a local
- install in your own home directory:
-
- ./configure --prefix=$HOME
- make
- make install
-
- MORE OPTIONS
- ------------
-
- To force configure to use the standard cc compiler if both cc and gcc are
- present, run configure like
-
- CC=cc ./configure
- or
- env CC=cc ./configure
-
- To force a static library compile, disable the shared library creation
- by running configure like:
-
- ./configure --disable-shared
-
- If you're a c-ares developer and use gcc, you might want to enable more
- debug options with the --enable-debug option.
-
- SPECIAL CASES
- -------------
- Some versions of uClibc require configuring with CPPFLAGS=-D_GNU_SOURCE=1
- to get correct large file support.
-
- The Open Watcom C compiler on Linux requires configuring with the variables:
-
- ./configure CC=owcc AR="$WATCOM/binl/wlib" AR_FLAGS=-q \
- RANLIB=/bin/true STRIP="$WATCOM/binl/wstrip" CFLAGS=-Wextra
-
-
-Win32
-=====
-
- Building Windows DLLs and C run-time (CRT) linkage issues
- ---------------------------------------------------------
-
- As a general rule, building a DLL with static CRT linkage is highly
- discouraged, and intermixing CRTs in the same app is something to
- avoid at any cost.
-
- Reading and comprehension of Microsoft Knowledge Base articles
- KB94248 and KB140584 is a must for any Windows developer. Especially
- important is full understanding if you are not going to follow the
- advice given above.
-
- KB94248 - How To Use the C Run-Time
- http://support.microsoft.com/kb/94248/en-us
-
- KB140584 - How to link with the correct C Run-Time (CRT) library
- http://support.microsoft.com/kb/140584/en-us
-
- KB190799 - Potential Errors Passing CRT Objects Across DLL Boundaries
- http://msdn.microsoft.com/en-us/library/ms235460
-
- If your app is misbehaving in some strange way, or it is suffering
- from memory corruption, before asking for further help, please try
- first to rebuild every single library your app uses as well as your
- app using the debug multithreaded dynamic C runtime.
-
- MingW32
- -------
-
- Make sure that MinGW32's bin dir is in the search path, for example:
-
- set PATH=c:\mingw32\bin;%PATH%
-
- then run 'make -f Makefile.m32' in the root dir.
-
- Cygwin
- ------
-
- Almost identical to the unix installation. Run the configure script in the
- c-ares root with 'sh configure'. Make sure you have the sh executable in
- /bin/ or you'll see the configure fail toward the end.
-
- Run 'make'
-
- Dev-Cpp
- -------
-
- See the separate INSTALL.devcpp file for details.
-
- MSVC 6 caveats
- --------------
-
- If you use MSVC 6 it is required that you use the February 2003 edition PSDK:
- http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm
-
- MSVC from command line
- ----------------------
-
- Run the 'vcvars32.bat' file to get a proper environment. The
- vcvars32.bat file is part of the Microsoft development environment and
- you may find it in 'C:\Program Files\Microsoft Visual Studio\vc98\bin'
- provided that you installed Visual C/C++ 6 in the default directory.
-
- Further details in README.msvc
-
- MSVC IDES
- ---------
-
- Details in README.msvc
-
- Important static c-ares usage note
- ----------------------------------
-
- When building an application that uses the static c-ares library, you must
- add '-DCARES_STATICLIB' to your CFLAGS. Otherwise the linker will look for
- dynamic import symbols.
-
-
-IBM OS/2
-========
- Building under OS/2 is not much different from building under unix.
- You need:
-
- - emx 0.9d
- - GNU make
- - GNU patch
- - ksh
- - GNU bison
- - GNU file utilities
- - GNU sed
- - autoconf 2.13
-
- If during the linking you get an error about _errno being an undefined
- symbol referenced from the text segment, you need to add -D__ST_MT_ERRNO__
- in your definitions.
-
- If you're getting huge binaries, probably your makefiles have the -g in
- CFLAGS.
-
-
-QNX
-===
- (This section was graciously brought to us by David Bentham)
-
- As QNX is targeted for resource constrained environments, the QNX headers
- set conservative limits. This includes the FD_SETSIZE macro, set by default
- to 32. Socket descriptors returned within the c-ares library may exceed this,
- resulting in memory faults/SIGSEGV crashes when passed into select(..)
- calls using fd_set macros.
-
- A good all-round solution to this is to override the default when building
- c-ares, by overriding CFLAGS during configure, example
- # configure CFLAGS='-DFD_SETSIZE=64 -g -O2'
-
-
-RISC OS
-=======
- The library can be cross-compiled using gccsdk as follows:
-
- CC=riscos-gcc AR=riscos-ar RANLIB='riscos-ar -s' ./configure \
- --host=arm-riscos-aof --without-random --disable-shared
- make
-
- where riscos-gcc and riscos-ar are links to the gccsdk tools.
- You can then link your program with c-ares/lib/.libs/libcares.a
-
-
-NetWare
-=======
- To compile libcares.a / libcares.lib you need:
- - either any gcc / nlmconv, or CodeWarrior 7 PDK 4 or later.
- - gnu make and awk running on the platform you compile on;
- native Win32 versions can be downloaded from:
- http://www.gknw.net/development/prgtools/
- - recent Novell LibC SDK available from:
- http://developer.novell.com/ndk/libc.htm
- - or recent Novell CLib SDK available from:
- http://developer.novell.com/ndk/clib.htm
-
- Set a search path to your compiler, linker and tools; on Linux make
- sure that the var OSTYPE contains the string 'linux'; set the var
- NDKBASE to point to the base of your Novell NDK; and then type
- 'make -f Makefile.netware' from the top source directory;
-
-
-Android
-=======
- Method using a configure cross-compile (tested with Android NDK r7b):
- - prepare the toolchain of the Android NDK for standalone use; this can
- be done by invoking the script:
- ./tools/make-standalone-toolchain.sh
- which creates a usual cross-compile toolchain. Lets assume that you put
- this toolchain below /opt then invoke configure with something like:
- export PATH=/opt/arm-linux-androideabi-4.4.3/bin:$PATH
- ./configure --host=arm-linux-androideabi [more configure options]
- make
- - if you want to compile directly from our GIT repo you might run into
- this issue with older automake stuff:
- checking host system type...
- Invalid configuration `arm-linux-androideabi':
- system `androideabi' not recognized
- configure: error: /bin/sh ./config.sub arm-linux-androideabi failed
- this issue can be fixed with using more recent versions of config.sub
- and config.guess which can be obtained here:
- http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree
- you need to replace your system-own versions which usually can be
- found in your automake folder:
- find /usr -name config.sub
-
-
-CROSS COMPILE
-=============
- (This section was graciously brought to us by Jim Duey, with additions by
- Dan Fandrich)
-
- Download and unpack the c-ares package.
-
- 'cd' to the new directory. (e.g. cd c-ares-1.7.6)
-
- Set environment variables to point to the cross-compile toolchain and call
- configure with any options you need. Be sure and specify the '--host' and
- '--build' parameters at configuration time. The following script is an
- example of cross-compiling for the IBM 405GP PowerPC processor using the
- toolchain from MonteVista for Hardhat Linux.
-
- (begin script)
-
- #! /bin/sh
-
- export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin
- export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include"
- export AR=ppc_405-ar
- export AS=ppc_405-as
- export LD=ppc_405-ld
- export RANLIB=ppc_405-ranlib
- export CC=ppc_405-gcc
- export NM=ppc_405-nm
-
- ./configure --target=powerpc-hardhat-linux \
- --host=powerpc-hardhat-linux \
- --build=i586-pc-linux-gnu \
- --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local \
- --exec-prefix=/usr/local
-
- (end script)
-
- You may also need to provide a parameter like '--with-random=/dev/urandom'
- to configure as it cannot detect the presence of a random number
- generating device for a target system. The '--prefix' parameter
- specifies where c-ares will be installed. If 'configure' completes
- successfully, do 'make' and 'make install' as usual.
-
- In some cases, you may be able to simplify the above commands to as
- little as:
-
- ./configure --host=ARCH-OS
-
-
-PORTS
-=====
- This is a probably incomplete list of known hardware and operating systems
- that c-ares has been compiled for. If you know a system c-ares compiles and
- runs on, that isn't listed, please let us know!

+In particular, if not using CMake you will need to run `./buildconf` (Unix) or
+`buildconf.bat` (Windows) to generate build files, and for the former
+you will need a local installation of Autotools. If using CMake the steps are

+
+AutoTools Build
+===============
+
+### General Information, works on most Unix Platforms (Linux, FreeBSD, etc)

+
+
+CMake builds
+============
+
+Current releases of c-ares introduce a CMake v3+ build system that has been
+tested on most platforms including Windows, Linux, FreeBSD, MacOS, AIX and
+Solaris.
+
+In the most basic form, building with CMake might look like:
+
+```sh
+cd /path/to/cmake/source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/cares ..
+make
+sudo make install
+```
+
+Options
+-------
+
+Options to CMake are passed on the command line using "-D${OPTION}=${VALUE}".
+The values defined are all boolean and take values like On, Off, True, False.
+
+* CARES_STATIC - Build the static library (off by default)
+* CARES_SHARED - Build the shared library (on by default)
+* CARES_INSTALL - Hook in installation, useful to disable if chain building
+* CARES_STATIC_PIC - Build the static library as position-independent (off by
+ default)
+
+
+Ninja
+-----
+
+Ninja is the next-generation build system meant for generators like CMake that
+heavily parallize builds. Its use is very similar to the normal build:
+
+```sh
+cd /path/to/cmake/source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/cares -G "Ninja" ..
+ninja
+sudo ninja install
+```
+
+Windows MSVC Command Line
+-------------------------
+
+```
+cd \path\to\cmake\source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=C:\cares -G "NMake Makefiles" ..
+nmake
+nmake install
+```
+
+Windows MinGW-w64 Command Line via MSYS
+---------------------------------------
+```
+cd \path\to\cmake\source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=C:\cares -G "MSYS Makefiles" ..
+make

- How to build using Visual Studio 6 IDE
- --------------------------------------
-
- A VC++ 6.0 reference workspace (vc6aws.dsw) is available within the 'vc'
- folder to allow proper building of the library and sample programs.
-
- 1) Open the vc6aws.dsw workspace with MSVC6's IDE.
- 2) Select 'Build' from top menu.
- 3) Select 'Batch Build' from dropdown menu.
- 4) Make sure that the sixteen project configurations are 'checked'.
- 5) Click on the 'Build' button.
- 6) Once the sixteen project configurations are built you are done.
-
- Dynamic and static c-ares libraries are built in debug and release flavours,
- and can be located each one in its own subdirectory, dll-debug, dll-release,
- lib-debug and lib-release, all of them below the 'vc\cares' subdirectory.
-
- In the same way four executable versions of each sample program are built,
- each using its respective library. The resulting sample executables are
- located in its own subdirectory, dll-debug, dll-release, lib-debug and
- lib-release, below the 'vc\acountry', 'vc\adig' and 'vc\ahost'folders.
-
- These reference VC++ 6.0 configurations are generated using the dynamic CRT.
-
-
- How to build using Visual Studio 2003 or newer IDE
- --------------------------------------------------
-
- First you have to convert the VC++ 6.0 reference workspace and project files
- to the Visual Studio IDE version you are using, following next steps:
-
- 1) Open vc\vc6aws.dsw with VS20XX.
- 2) Allow VS20XX to update all projects and workspaces.
- 3) Save ALL and close VS20XX.
- 4) Open vc\vc6aws.sln with VS20XX.
- 5) Select batch build, check 'all' projects and click 'build' button.

+c-ares security
+===============
+
+This document is intended to provide guidance on how security vulnerabilities
+should be handled in the c-ares project.
+
+Publishing Information
+----------------------
+
+All known and public c-ares vulnerabilities will be listed on [the c-ares web
+site](https://c-ares.haxx.se/vulns.html).
+
+Security vulnerabilities should not be entered in the project's public bug
+tracker unless the necessary configuration is in place to limit access to the
+issue to only the reporter and the project's security team.
+
+Vulnerability Handling
+----------------------
+
+The typical process for handling a new security vulnerability is as follows.
+
+No information should be made public about a vulnerability until it is
+formally announced at the end of this process. That means, for example that a
+bug tracker entry must NOT be created to track the issue since that will make
+the issue public and it should not be discussed on the project's public
+mailing list. Also messages associated with any commits should not make any
+reference to the security nature of the commit if done prior to the public
+announcement.
+
+- The person discovering the issue, the reporter, reports the vulnerability
+ privately to `c-ares-security@haxx.se`. That's an email alias that reaches a
+ handful of selected and trusted people.
+
+- Messages that do not relate to the reporting or managing of an undisclosed
+ security vulnerability in c-ares are ignored and no further action is
+ required.
+
+- A person in the security team sends an e-mail to the original reporter to
+ acknowledge the report.
+
+- The security team investigates the report and either rejects it or accepts
+ it.
+
+- If the report is rejected, the team writes to the reporter to explain why.
+
+- If the report is accepted, the team writes to the reporter to let him/her
+ know it is accepted and that they are working on a fix.
+
+- The security team discusses the problem, works out a fix, considers the
+ impact of the problem and suggests a release schedule. This discussion
+ should involve the reporter as much as possible.
+
+- The release of the information should be "as soon as possible" and is most
+ often synced with an upcoming release that contains the fix. If the
+ reporter, or anyone else, thinks the next planned release is too far away
+ then a separate earlier release for security reasons should be considered.
+
+- Write a security advisory draft about the problem that explains what the
+ problem is, its impact, which versions it affects, solutions or
+ workarounds, when the release is out and make sure to credit all
+ contributors properly.
+
+- Request a CVE number from
+ [distros@openwall](http://oss-security.openwall.org/wiki/mailing-lists/distros)
+ when also informing and preparing them for the upcoming public security
+ vulnerability announcement - attach the advisory draft for information. Note
+ that 'distros' won't accept an embargo longer than 19 days.
+
+- Update the "security advisory" with the CVE number.
+
+- The security team commits the fix in a private branch. The commit message
+ should ideally contain the CVE number. This fix is usually also distributed
+ to the 'distros' mailing list to allow them to use the fix prior to the
+ public announcement.
+
+- At the day of the next release, the private branch is merged into the master
+ branch and pushed. Once pushed, the information is accessible to the public
+ and the actual release should follow suit immediately afterwards.
+
+- The project team creates a release that includes the fix.
+
+- The project team announces the release and the vulnerability to the world in
+ the same manner we always announce releases. It gets sent to the c-ares
+ mailing list and the oss-security mailing list.
+
+- The security web page on the web site should get the new vulnerability
+ mentioned.
+
+C-ARES-SECURITY (at haxx dot se)
+--------------------------------
+
+Who is on this list? There are a couple of criteria you must meet, and then we
+might ask you to join the list or you can ask to join it. It really isn't very
+formal. We basically only require that you have a long-term presence in the
+c-ares project and you have shown an understanding for the project and its way
+of working. You must've been around for a good while and you should have no
+plans in vanishing in the near future.
+
+We do not make the list of partipants public mostly because it tends to vary
+somewhat over time and a list somewhere will only risk getting outdated.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

+\`configure' configures c-ares 1.17.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+ --with-random=FILE read randomness from FILE (default=/dev/urandom)
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ LT_SYS_LIBRARY_PATH
+ User-defined run-time library search path.
+ CXXCPP C++ preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
